As Stress Mounts, Self-Control Goes Out the Window

As Stress Mounts, Self-Control Goes Out the Window - Yahoo! News

By Alison McCook Thu Apr 21, 2:34 PM ET

During times of stress, we’re less able to hold ourselves back from unhealthy temptations, new study findings indicate.

Australian researchers found that during exam periods, students smoked more cigarettes, drank more high-caffeine drinks, ate less healthy foods, kept up with fewer household chores, neglected commitments, and monitored spending less.

“The results tell us that during periods of high stress - such as examination periods for students - we may see a relapse in behaviors that we had successfully controlled in the past, such as smoking,” lead author Megan Oaten of Macquarie University in Sydney told Reuters Health.

“These findings have practical importance because they illustrate that at times of stress we are particularly vulnerable to breakdowns in self-control,” she added. “Therefore, we should not ask too much of ourselves during such a period.”

Oaten pointed out that handling stress itself takes self-control. “So, the work required to cope with stress consumes a lot of our self-control strength, and leaves us less able to control our behavior,” Oaten said.

During the study, Oaten and her co-author, Ken Cheng, asked 57 students about their typical self-control, then re-interviewed them 4 weeks later, when half were coping with a high-stress exam period.

The researchers found that, during exams, students were less likely to control their behaviors, reporting that they ate more junk food, exercised less, and left more dishes in the sink. They also neglected to shave, brush and floss their teeth, wash their hair, change their clothes and do laundry.

Stressed out students also smoked an average of 7 additional cigarettes each day, and drank 7 extra cups of caffeinated drinks each week.

In contrast, students not coping with exams had no increase in self-indulgent behaviors, suggesting their self-control was as strong as ever, the authors report in the Journal of Social and Clinical Psychology.

These findings suggest that people should be extra careful during times of stress, Oaten noted. “It appears that people can only control so many behaviors at any one time, and should therefore avoid taking on too much at once, particularly during periods of stress.”

Developing stress management skills may also ward off lapses, by leaving more self-control reserves available to fend off the urge to overeat and smoke, she said.

Statins Lower Prostate Cancer Risk

Studies Also Tout Vitamin D for Lung Cancer, Calcium for Colon Cancer

April 18, 2005 (Anaheim, Calif.) — Certain cholesterol-lowering drugs may help prevent prostate cancer, according to evidence presented at a meeting of cancer experts, while other studies showed the benefits of nutrients to fight lung and colon cancers.

Statins Cut Prostate Cancer Risk

In the latest research to show that the popular cholesterol-lowering drugs known as statins are good for more than the heart,statins are good for more than the heart, a 10-year study of more than 30,000 men shows that statins may slash the risk of advanced prostate cancer in half.

“The results are promising,” says Elizabeth Platz, ScD, MPH, a cancer epidemiologist at Johns Hopkins Bloomberg School of Public Health in Baltimore. “The longer the men took the statins, the lower the risk of advanced prostate cancer.”

Statin use did not appear to lower the chance a man would develop early cancer that was still confined to the prostate itself, she tells WebMD.

Statins used to treat high cholesterol include Crestor, Lipitor, Pravachol, and Zocor.

Advanced Prostate Cancer Falls 50%

The new study, presented at the annual meeting of the American Association for Cancer Research, included more than 34,000 men who were free of prostate cancer in 1990.

Every two years, the men were asked whether they took cholesterol-lowering drugs — statins or other drugs — and if they had been diagnosed with prostate cancer. “If they said they had cancer, we confirmed the diagnosis,” Platz says.

By 2000, 2,074 men had developed prostate cancer. Of these, 283 cases were advanced prostate cancer, with many of them having already spread outside the prostate.

Compared with men who didn’t take cholesterol-lowering drugs, those who did take them had nearly one-half the risk of developing advanced prostate cancer. Risk decreased with increasing duration of use, Platz notes.

So how did she know that statins — not other cholesterol-lowering drugs — were responsible for the protective effects?

“We can’t rule anything out,” Platz says. “But on the 2000 questionnaire, we specifically asked about statins and found that 90% of men on a cholesterol-lowering drug were on a statin.”

Plus, some laboratory and animal studies hint of a biological rationale for using the drugs, she says. For example, statins may promote cancer cell death.

Statins Ready for Prime Time?

Smaller studies have shown that statin use is associated with a reduced risk of a variety of cancers, including that of the prostate, but this is the first time the researchers tracked medication use before the study participants developed cancer, Platz says.

The better design of the study is what makes the observation so exciting, says Andrew J. Dannenberg, MD, director of cancer prevention at New York Presbyterian Hospital-Cornell in New York City.

“This study stands apart from previous work that suggested a protective effect,” he tells WebMD. “It was really well done. It appears that statin use is associated with a better prognosis.”

But until the findings are confirmed in other large, well-designed studies, both Platz and Dannenberg caution that it’s too soon to recommend that men at high risk for prostate cancerhigh risk for prostate cancer start taking statins for their antitumor properties.

Vitamin D for Lung Cancer

Another study revealed that patients diagnosed with early lung cancer may want to reach for vitamin D supplements and get out in the sun. The body produces vitamin D when the skin is exposed to the sun.

The preliminary study looked at 450 men and women with early stage non-small-cell lung cancer. Researchers were looking at the potential effects of vitamin D in the diet and supplements, as well as from sun exposure. They compared people with high vitamin D intake who had surgery in the summer months to those with low vitamin D intake who had wintertime operations.

The high-vitamin D group was more than twice as likely to be alive five years later.

While milk and fish are rich in vitamin D, it’s nearly impossible to get the high amounts needed for the protective effects just from food — the equivalent of about 600 IU a day, says researcher Wei Zhou, PhD, of the Harvard School of Public Health.

Calcium for Colon Cancer

Calcium supplements have been linked to a lower risk of colon cancer.lower risk of colon cancer. Now researchers have found that long-term use of calcium supplements protects against the development of potentially precancerous colon polyps for years after you stop taking them.

Dartmouth researchers followed people at high risk for colon polyps who had been randomly assigned to take either 1,200 milligrams of calcium supplements for four years or a placebo.

During the first five years after they stopped taking the supplements, those who had taken calcium during the study were still about one-third less likely to develop colon polyps than those on a placebo.

But after five years, the beneficial effects started to taper off and nearly disappeared by 10 years later, says John Baron, MD.

Green tea shown to prevent prostate cancer

Green tea shown to prevent prostate cancer

21 Apr 2005

After a year’s oral administration of green tea catechins (GTCs), only one man in a group of 32 at high risk for prostate cancer developed the disease, compared to nine out of 30 in a control, according to a team of Italian researchers from the University of Parma and University of Modena and Reggio Emilia led by Saverio Bettuzzi, Ph.D.

Their results were reported here today at the 96th Annual Meeting of the American Association for Cancer Research.

“Numerous earlier studies, including ours, have demonstrated that green tea catechins, or pure EGCG (a major component of GTCs), inhibited cancer cell growth in laboratory models,” Bettuzzi explained. “We wanted to conduct a clinical trial to find out whether catechins could prevent cancer in men. The answer clearly is yes.”

Earlier research demonstrated primarily that green tea catechins were safe for use in humans. Bettuzzi and his colleagues had found that EGCG targets prostate cancer cells specifically for death, without damaging the benign controls. They identified Clusterin, the most important gene involved in apoptosis, or programmed cell death in the prostate, as a possible mediator of catechins action. “EGCG induced death in cancer cells, not normal cells, inducing Clusterin expression” said Bettuzzi.

To gauge susceptibility for prostate cancer among their research subjects, the team of Italian scientists recruited men with high-grade prostatic intraepithelial neoplasia - premalignant lesions that presage invasive prostate cancer within one year in nearly a third of cases and for which no treatment was given.

Eligible men were between 45 and 75 years of age. Vegetarians and men consuming green tea or derived products, or those taking anti-oxidants or following anti-androgenic therapy were excluded.

Of the 62 volunteers, 32 received three tablets per day of 200 mg each GTCs; the remainder were given a placebo. Follow-up biopsies were administered after six months and again at one year. Only one case of prostate cancer was diagnosed among those receiving 600 mg daily of GTCs, while nine cases were found in the untreated group. The 30 percent incidence rate among controls is consistent with previous findings, as was the absence of significant side effects or adverse reactions.

The interest in green tea catechins and other polyphenols - antioxidants found in many plants that give some flowers, fruits and vegetables their coloring - derives from traditional Chinese medicine, and the observation of lower cancer rates among Asian populations.

Bettuzzi observed that the Mediterranean diet is rich in vegetables, and lower rates of prostate cancer are found in that region, as well.

The 600 mg-per-day dosage of caffeine-free, total catechins (50 percent of which is EGCG) given to participants in the Italian study is one or two times the amount of green tea consumed daily in China, where ten to 20 cups a day is normal.

“We still don’t know enough about the biological processes leading to prostate cancer,” Bettuzzi noted. “The only thing we know for sure is that prostate cancer is diffuse, related to age and more prevalent in the West. Thus, prevention could be the best way to fight it. Although our follow-up will continue for up to five years, a larger, confirmatory study is needed.”

Even so, Bettuzzi hints at the exciting prospect of using green tea catechins as a prophylactic against prostate cancer in men believed to be at higher risk, such as the elderly, African-Americans, and those with a family history of prostate cancer.

Chili, Broccoli Help Prevent Cancer - Studies

Chili, Broccoli Help Prevent Cancer - Studies - Yahoo! News

Broccoli and red chili peppers may help fight cancer by slowing the growth of cancerous tumor cells, U.S. researchers reported on Tuesday.

They may be especially helpful in hard-to-treat cancers such as pancreatic and ovarian cancer, the team at the University of Pittsburgh said.

“In our studies, we decided to look at two particular cancers — ovarian and pancreatic — with low survival rates, to ascertain the contribution of diet and nutrition to the development of these cancers,” said Sanjay Srivastava, who led the study.

“We discovered that red chili pepper and broccoli appear to be effective inhibitors of the cancer process.”

Speaking to a meeting of the American Association for Cancer Research in Anaheim, California, Srivastava said he and colleagues tested capsaicin, which makes peppers hot, against pancreatic cancer cells in a lab dish.

The compound caused the cancer cells to self-destruct in a process called apoptosis, while not affecting normal pancreatic cells.

“Our results demonstrate that capsaicin is a potent anticancer agent, induces apoptosis in cancer cells and produces no significant damage to normal pancreatic cells, indicating its potential use as a novel chemotherapeutic agent for pancreatic cancer,” Srivastava said.

His team also examined phenethyl isothiocyanate (PEITC), a constituent of cruciferous vegetables such as broccoli, on ovarian cancer cells.

PEITC interfered with a protein called epidermal growth factor receptor, which is involved in the growth of ovarian and other cancerous tumors.

The studies may help explain why people who eat large amounts of fruits and vegetables have a lower risk of cancer, Srivastava said.

Friendly bacteria in humans may protect against HIV

Friendly bacteria in humans may protect against HIV

19 Apr 2005

Scientists have identified good bacteria already living in some humans that target and trap HIV and may protect against infection. They report their findings today at the 2005 American Society for Microbiology Beneficial Microbes Conference.

“I believe every life form has its natural enemy, and HIV should not be the exception,” says Dr. Lin Tao, Associate Professor of the Department of Oral Biology, College of Dentistry, University of Illinois at Chicago. “If we can find its natural enemy, we can control the spread of HIV naturally and cost-effectively, just as we use cats to control mice.”

The bacteria are strains of lactobacillus, commonly found colonizing the oral and vaginal cavities of humans. They do not cause disease. They target HIV because the virus is coated with the sugar mannose, which they use as a food source.

“Different bacteria have different sugar preferences,” says Tao. “To block HIV, however, we needed to find bacteria that prefer the unusual sugar mannose and thus can capture it.”

To identify bacteria that target mannose, Tao and his colleagues isolated oral and vaginal lactobacilli from healthy humans and tested the ability of different strains to bind to baker’s yeast, another microorganism coated with mannose-rich sugars. They found a small group of lactobacilli that bound to mannose and further testing against HIV revealed two strains that specifically trapped the virus and blocked infection.

Due to high rates of mutation, repeated attempts at developing a vaccine to protect against HIV have failed. Inoculating the major mucosal surfaces where HIV transmission occurs with the HIV-capturing lactobacilli may provide a safe and cost-efficient method for preventing the spread of HIV, says Tao.

“This method can protect infants against HIV in breast milk and women against HIV upon sexual contact unobtrusively and inconspicuously via fermented foods or feminine products,” says Tao. “If the method can be successfully developed and applied, the global spread of HIV can be controlled rapidly, effectively and safely.”

“The major roadblock in the development of this technology is the lack of financial support. Drug companies and venture capitalists are not interested because the beneficiary populations are infants and women in poor countries,” says Tao. He is currently seeking sponsorship from charities or philanthropists to develop this technology.

Tao’s colleagues include Sylvia Pavlova, Sarah Carlson, Michael Caffrey, and Amy Jacobs at UIC as well as Gregory Spear and Joshua Anzinger at Rush University, Chicago. The research was supported in part by AmFAR/Concerned Parents for AIDS Research, the National Institutes of Health (NIAID, NIDCR), and the International Association for Dental Research/GlaxoSmithKline Innovation in Oral Care Award.

The American Society for Microbiology, headquartered in Washington, D.C., is the largest single life science association, with 42,000 members worldwide. Its members work in educational, research, industrial, and government settings on issues such as the environment, the prevention and treatment of infectious diseases, laboratory and diagnostic medicine, and food and water safety. The ASM’s mission is to gain a better understanding of basic life processes and to promote the application of this knowledge for improved health and economic and environmental well-being.

Tea may help prevent diabetes and cataracts

Tea may help prevent diabetes and cataracts

19 Apr 2005

Add another line to the list of benefits from drinking tea: New research in animals suggests that tea may be a simple, inexpensive means of preventing diabetes and its ensuing complications, including cataracts. The report, scheduled to appear in the May 4 print issue of the American Chemical Society’s Journal of Agricultural and Food Chemistry, was published March 31 on the journal’s Web site. ACS is the world’s largest scientific society.

Researchers fed green and black tea to diabetic rats for three months and then monitored the chemical composition of the rats’ blood and eye lenses. At levels that would be equivalent to less than five cups of tea per day for a human, both teas significantly inhibited cataract formation relative to a control group which did not get tea, they say. The researchers found that both teas decreased glucose levels, which in turn affects other biochemical pathways that accelerate diabetic complications such as cataracts.

“Most people, scientists included, believe that green tea has more health benefits than black tea,” says Joe Vinson, Ph.D., a chemist at the University of Scranton (Penn.) and lead author of the paper. In combination with Vinson’s earlier research showing that green tea and black tea equally inhibit atherosclerosis - a major risk factor for heart disease - the findings suggest that both drinks could play a part in curbing two of the most widespread maladies in the United States today.

The American Chemical Society is a nonprofit organization, chartered by the U.S. Congress, with a multidisciplinary membership of more than 158,000 chemists and chemical engineers. It publishes numerous scientific journals and databases, convenes major research conferences and provides educational, science policy and career programs in chemistry. Its main offices are in Washington, D.C., and Columbus, Ohio.

Nutrition Notes: Is Chocolate Good for You?

Kansas City infoZine - Nutrition Notes: Is Chocolate Good for You? - USA

By Karen Collins, MS, RD, CDN - Recent research shows that chocolate can provide natural health-promoting substances called flavonoids.

HealthAmerican Institute for Cancer Research - infoZine - Since flavonoids seem to help prevent heart disease and cancer, the idea of eating chocolate sounds like a tempting and delicious way to better your health. The complete message is, however, that although chocolate might be preferable to other treats, it is no substitute for vegetables and fruits, which also contain flavonoids.

The flavonoids in chocolate that laboratory studies demonstrate to have powerful antioxidant effects are called flavanols and procyanidins. These two compounds come from the flavonoid “family” that includes resveratrol, found in grape juice, and EGCG, found in green tea. When people consume these substances in chocolate and cocoa, the antioxidant status of their blood increases. This rise in antioxidant levels helps protect us from damage to the heart and blood vessels, while it also guards our DNA from damage that can lead to cancer. In addition, the flavanols and procyanidins in chocolate improve the function and flow of blood vessels and help control inflammation.

The antioxidants in chocolate have generated a lot of interest because studies show that these compounds are more powerful antioxidants than EGCG in tea, which is a strong antioxidant. One study that compared the total antioxidant activity in single servings of cocoa, green tea, black tea and red wine scored cocoa markedly higher than the rest.

Yet the flavonoid content of cocoa and chocolate is highly variable. The more cocoa in a chocolate product, the higher the antioxidant flavonoid content is. Because dark chocolate is more concentrated in cocoa content, it is higher in flavonoids than milk chocolate. For this reason, dark chocolate is used in research studies. White chocolate has no cocoa content.

A cup of hot or cold cocoa may sound like a health drink loaded with antioxidants, but almost all cocoa drink mixes contain cocoa treated with alkali (also called Dutch cocoa) to produce a darker, richer taste. Unfortunately, this process drastically reduces flavonoid content. Unless you find a chocolate mix made with untreated cocoa, start with plain cocoa (not Dutch) and add your own sweetener and milk to make a flavonoid-rich cup.

Surprisingly, the fat content of chocolate is not a reason to avoid it. Technically, chocolate contains saturated fat, but the particular type of saturated fat - stearic acid - is unique because it does not raise blood cholesterol. Studies show that neither dark or milk chocolate is a cholesterol concern in moderate amounts. But keep in mind that other ingredients added to some chocolate candies can change their nutrition impact.

But one of the reasons you shouldn’t rely on chocolate for antioxidants, in the place of vegetables and fruits, is the calorie load. A small piece of dark chocolate has only 50 calories, but most candy bars contain at least 200. In comparison, a serving of vegetables and fruits contains a generous amount of health-promoting phytochemicals and only 25 to 80 calories. An antioxidant-rich serving of green tea has no calories at all.

Besides, vegetables and fruits have more than flavonoids. They provide vitamins, minerals like magnesium and potassium, and phytochemicals that protect our health in other ways. Some, for example, block the activation of carcinogens, while others interfere with the life cycle of cancer cells and promote their destruction.

Recent research on the flavonoids in chocolate implies that we can enjoy limited amounts of this sweet treat without guilt. But this news shouldn’t discourage us from eating a mostly plant-based diet loaded with vegetables and fruits.

Government Issues 12 New Food Pyramids

Government Issues 12 New Food Pyramids - Yahoo! News

By LIBBY QUAID, Associated Press Writer 58 minutes ago

Concerned about steadily expanding waistlines, the government flipped the food pyramid on its side, adding a staircase for exercise and giving consumers 12 individually-tailored models for improving their eating habits.

Inside the pyramid released Tuesday, rainbow-colored bands representing different food groups run vertically from the tip to the base. The old single, triangle-shaped pyramid had a horizontal presentation of food categories that many found confusing.

Exercise is key to the new system. Fitness expert Denise Austin delivered a pep talk about the recommended 30 minutes of physical activity, represented on the new pyramids by the figure of a person climbing steps toward the tip. Also in store are new Internet tools to help follow the guidelines.

The new guide, dubbed “MyPyramid,” encourages Americans to customize their diet and exercise regime along 12 models geared to specific calorie needs and levels of physical activity.

Food groups are represented by six different colors: Orange for grains, green for vegetables, red for fruits, yellow for oils, blue for milk products and purple for meats and beans. The bands are wider for grains, vegetables, milk products and fruits, because people should eat more of them.

Agriculture Secretary Mike Johanns called the new guide “a system of information to help consumers understand how to put nutrition recommendations into action.”

People have steadily grown fatter since the food pyramid debuted in 1992. A report last month in The
New England Journal of Medicine contended that obesity, particularly in children, was shaving four to nine months off the average life expectancy.

Johanns said the 1992 pyramid had “become quite familiar, but few Americans follow the recommendations.” He said that knowledge about nutrition and food consumption patterns has grown significantly in the past dozen years and is reflected in the new food guidance symbols.

“If we don’t change these trends, our children may be the first generation that cannot look forward to a longer life span than their parents,” said Eric Bost, the Agriculture Department’s under secretary for food, nutrition and consumer services.

Food companies announced Tuesday they will distribute posters and guides for teachers and parents next fall aimed at reaching 4 million students. Materials for students to take home will be in both English and Spanish and will include math, nutrition and science activities.

One big change is intended to help people control their portion sizes. The old pyramid explained its advice in “serving” sizes, but now, to make its advice more understandable, the government will switch to cups, ounces and other household measures.

The switch was recommended in a 70-page booklet, “Dietary Guidelines for Americans 2005,” that was developed by a panel of scientists and doctors and released in January. As the basis for revising the pyramid, the guidelines emphasize choosing good carbohydrates over bad ones; for example, choosing bread made from whole-grain flour instead of white flour.

They also recommend eating 3 ounces of whole-grain foods a day; eating 2 cups of fruit and 2 1/2 cups of vegetables a day; and drinking 3 cups of fat-free or lowfat milk a day.

Besides the suggested 30 minutes of daily exercise to reduce the risk of chronic disease, the government also advises even more exercise to prevent weight gain or maintain weight loss.

In all, there were 23 general recommendations and 18 suggestions for older people, children and other special populations.

That’s too much to cram into a symbol that is supposed to be clipped out and stuck to the refrigerator, said Eric Hentges, director of the Agriculture Department’s Center for Nutrition Policy and Promotion.

The Agriculture Department will offer Web pages that let people appraise their diet and exercise habits. Such a tool has already been available through the agency’s Web site; the Interactive Healthy Eating Index has a notice on its home page that it will soon be updated.

Even if the symbol and online tools don’t motivate people to change their habits, they’ll still have some healthier choices. Food companies have been removing trans fats from their products and adding whole grains because of the government guidance.

“If you get the industry involved and make them feel that they’re doing a good thing and that they’re getting credit for doing a good thing, they’ll do it. They’ll change their product,” said K. Dun Gifford, president of Oldways Preservation Trust, a Boston-based think tank that specializes in food issues.

Critics have raised questions about the public relations agency hired to help create the new version of the pyramid. The firm, Porter Novelli, has food companies as clients, but both Agriculture Department and Porter Novelli officials have said the firm’s industry work is handled separately and there would be no conflict of interest.

Hentges said his staff of scientists, economists and nutritionists isn’t equipped to promote its new approach. If it’s not marketed effectively, he said, “then we’re not going to be able to get this behavior change or improve anything for Americans.”

There’s Nothing Deep About Depression

Category: Depression

The New York Times > Magazine > There’s Nothing Deep About Depression

By PETER D. KRAMER

Shortly after the publication of my book ‘’Listening to Prozac,'’ 12 years ago, I became immersed in depression. Not my own. I was contented enough in the slog through midlife. But mood disorder surrounded me, in my contacts with patients and readers. To my mind, my book was never really about depression. Taking the new antidepressants, some of my patients said they found themselves more confident and decisive. I used these claims as a jumping-off point for speculation: what if future medications had the potential to modify personality traits in people who had never experienced mood disorder? If doctors were given access to such drugs, how should they prescribe them? The inquiry moved from medical ethics to social criticism: what does our culture demand of us, in the way of assertiveness?

It was the medications’ extra effects — on personality, not on the symptoms of depression — that provoked this line of thought. For centuries, doctors have treated depressed patients, using medication and psychological strategies. Those efforts seemed uncontroversial. But authors do not determine the fate of their work. ‘’Listening to Prozac'’ became a ‘’best-selling book about depression.'’ I found myself speaking — sometimes about ethics, more often about mood disorders — with many audiences, in bookstores, at gatherings of the mentally ill and their families and at professional meetings. Invariably, as soon as I had finished my remarks, a hand would shoot up. A hearty, jovial man would rise and ask — always the same question — ‘’What if Prozac had been available in van Gogh’s time?'’

I understood what was intended, a joke about a pill that makes people blandly chipper. The New Yorker had run cartoons along these lines — Edgar Allan Poe, on Prozac, making nice to a raven. Below the surface humor were issues I had raised in my own writing. Might a widened use of medication deprive us of insight about our condition? But with repetition, the van Gogh question came to sound strange. Facing a man in great pain, headed for self-mutilation and death, who would withhold a potentially helpful treatment?

It may be that my response was grounded less in the intent of the question than in my own experience. For 20 years, I’d spent my afternoons working with psychiatric outpatients in Providence, R.I. As I wrote more, I let my clinical hours dwindle. One result was that more of my time was filled with especially challenging cases, with patients who were not yet better. The popularity of ‘’Listening to Prozac'’ meant that the most insistent new inquiries were from families with depressed members who had done poorly elsewhere. In my life as a doctor, unremitting depression became an intimate. It is poor company. Depression destroys families. It ruins careers. It ages patients prematurely.

Recent research has made the fight against depression especially compelling. Depression is associated with brain disorganization and nerve-cell atrophy. Depression appears to be progressive — the longer the episode, the greater the anatomical disorder. To work with depression is to combat a disease that harms patients’ nerve pathways day by day.

Nor is the damage merely to mind and brain. Depression has been linked with harm to the heart, to endocrine glands, to bones. Depressives die young — not only of suicide, but also of heart attacks and strokes. Depression is a multisystem disease, one we would consider dangerous to health even if we lacked the concept ‘’mental illness.'’

As a clinician, I found the what if challenge ever less amusing. And so I began to ask audience members what they had in mind. Most understood van Gogh to have suffered severe depression. His illness, they thought, conferred special vision. In a short story, Poe likens ‘’an utter depression of soul'’ to ‘’the hideous dropping off of the veil.'’ The questioners maintained this 19th-century belief, that depression reveals essence to those brave enough to face it. By this account, depression is more than a disease — it has a sacred aspect.

Other questioners set aside that van Gogh was actually ill. They took mood disorder to be a heavy dose of the artistic temperament, so that any application of antidepressants is finally cosmetic, remolding personality into a more socially acceptable form. For them, depression was less than a disease.

These attributions stood in contrast to my own belief, that depression is neither more nor less than a disease, but disease simply and altogether.

Audiences seemed to be aware of the medical perspective, even to endorse it — but not to have adopted it as a habit of mind. To underscore this inconsistency, I began to pose a test question: We say that depression is a disease. Does that mean that we want to eradicate it as we have eradicated smallpox, so that no human being need ever suffer depression again? I made it clear that mere sadness was not at issue. Take major depression, however you define it. Are you content to be rid of that condition?

Always, the response was hedged: aren’t we meant to be depressed? Are we talking about changing human nature?

I took those protective worries as expressions of what depression is to us. Asked whether we are content to eradicate arthritis, no one says, ‘’Well, the end-stage deformation, yes, but let’s hang on to tennis elbow, housemaid’s knee and the early stages of rheumatoid disease.'’ Multiple sclerosis, acne, schizophrenia, psoriasis, bulimia, malaria — there is no other disease we consider preserving. But eradicating depression calls out the caveats.

To this way of thinking, to oppose depression too completely is to be coarse and reductionist — to miss the inherent tragedy of the human condition. To be depressed, even gravely, is to be in touch with what matters most in life, its finitude and brevity, its absurdity and arbitrariness. To be depressed is to occupy the role of rebel and social critic. Depression, in our culture, is what tuberculosis was 100 years ago: illness that signifies refinement.

Having raised the thought experiment, I should emphasize that in reality, the possibility of eradicating depression is not at hand. If clinicians are better at ameliorating depression than we were 10 years ago — and I think we may be — that is because we are more persistent in our efforts, combining treatments and (when they succeed) sticking with them until they have a marked effect. But in terms of the tools available, progress in the campaign against depression has been plodding.

Still, it is possible to envisage general medical progress that lowers the rate of depression substantially — and then to think of a society that enjoys that result. What is lost, what gained? Which is also to ask: What stands in the way of our embracing the notion that depression is disease, nothing more?

This question has any number of answers. We idealize depression, associating it with perceptiveness, interpersonal sensitivity and other virtues. Like tuberculosis in its day, depression is a form of vulnerability that even contains a measure of erotic appeal. But the aspect of the romanticization of depression that seems to me to call for special attention is the notion that depression spawns creativity.

Objective evidence for that effect is weak. Older inquiries, the first attempts to examine the overlap of madness and genius, made positive claims for schizophrenia. Recent research has looked at mood disorders. These studies suggest that bipolar disorder may be overrepresented in the arts. (Bipolarity, or manic-depression, is another diagnosis proposed for van Gogh.) But then mania and its lesser cousin hypomania may drive productivity in many fields. One classic study hints at a link between alcoholism and literary work. But the benefits of major depression, taken as a single disease, have been hard to demonstrate. If anything, traits eroded by depression — like energy and mental flexibility — show up in contemporary studies of creativity.

How, then, did this link between creativity and depression arise? The belief that mental illness is a form of inspiration extends back beyond written history. Hippocrates was answering some such claim, when, around 400 B.C., he tried to define melancholy — an excess of ‘’black bile'’ — as a disease. To Hippocrates, melancholy was a disorder of the humors that caused epileptic seizures when it affected the body and caused dejection when it affected the mind. Melancholy was blamed for hemorrhoids, ulcers, dysentery, skin rashes and diseases of the lungs.

The most influential expression of the contrasting position — that melancholy confers special virtues — appears in the ‘’Problemata Physica,'’ or ‘’Problems,'’ a discussion, in question-and-answer form, of scientific conundrums. It was long attributed to Aristotle, but the surviving version, from the second century B.C., is now believed to have been written by his followers. In the 30th book of the ‘’Problems,'’ the author asks why it is that outstanding men — philosophers, statesmen, poets, artists, educators and heroes — are so often melancholic. Among the ancients, the strongmen Herakles and Ajax were melancholic; more contemporaneous examples cited in the ‘’Problems'’ include Socrates, Plato and the Spartan general Lysander. The answer given is that too much black bile leads to insanity, while a moderate amount creates men ‘’superior to the rest of the world in many ways. ‘’

The Greeks, and the cultures that succeeded them, faced depression poorly armed. Treatment has always been difficult. Depression is common and spans the life cycle. When you add in (as the Greeks did) mania, schizophrenia and epilepsy, not to mention hemorrhoids, you encompass a good deal of what humankind suffers altogether. Such an impasse calls for the elaboration of myth. Over time, ‘’melancholy ‘’ became a universal metaphor, standing in for sin and innocent suffering, self-indulgence and sacrifice, inferiority and perspicacity.

The great flowering of melancholy occurred during the Renaissance, as humanists rediscovered the ‘’Problems.'’ In the late 15th century, a cult of melancholy flourished in Florence and then was taken back to England by foppish aristocratic travelers who styled themselves artists and scholars and affected the melancholic attitude and dress. Most fashionable of all were ‘’melancholic malcontents,'’ irritable depressives given to political intrigue. One historian, Lawrence Babb, describes them as ‘’black-suited and disheveled . . . morosely meditative, taciturn yet prone to occasional railing.'’

In dozens of stage dramas from the period, the principal character is a discontented melancholic. ‘’Hamlet'’ is the great example. As soon as Hamlet takes the stage, an Elizabethan audience would understand that it is watching a tragedy whose hero’s characteristic flaw will be a melancholic trait, in this case, paralysis of action. By the same token, the audience would quickly accept Hamlet’s spiritual superiority, his suicidal impulses, his hostility to the established order, his protracted grief, solitary wanderings, erudition, impaired reason, murderousness, role-playing, passivity, rashness, antic disposition, ‘’dejected haviour of the visage'’ and truck with graveyards and visions.

‘’Hamlet'’ is arguably the seminal text of our culture, one that cements our admiration for doubt, paralysis and alienation. But seeing ‘’Hamlet'’ in its social setting, in an era rife with melancholy as an affected posture, might make us wonder how much of the historical association between melancholy and its attractive attributes is artistic conceit.

In literature, the cultural effects of depression may be particularly marked. Writing, more than most callings, can coexist with a relapsing and recurring illness. Composition does not require fixed hours; poems or essays can be set aside and returned to on better days. And depression is an attractive subject. Superficially, mental pain resembles passion, strong emotion that stands in opposition to the corrupt world. Depression can have a picaresque quality — think of the journey through the Slough of Despond in John Bunyan’s ‘’Pilgrim’s Progress.'’ Over the centuries, narrative structures were built around the descent into depression and the recovery from it. Lyric poetry, religious memoir, the novel of youthful self-development — depression is an affliction that inspires not just art but art forms. And art colors values. Where the unacknowledged legislators of mankind are depressives, dark views of the human condition will be accorded special worth.

Through the ‘’anxiety of influence,'’ heroic melancholy cast its shadow far forward, onto romanticism and existentialism. At a certain point, the transformation begun in the Renaissance reaches completion. It is no longer that melancholy leads to heroism. Melancholy is heroism. The challenge is not battle but inner strife. The rumination of the depressive, however solipsistic, is deemed admirable. Repeatedly, melancholy returns to fashion.

As I spoke with audiences about mood disorders, I came to believe that part of what stood between depression and its full status as disease was the tradition of heroic melancholy. Surely, I would be asked when I spoke with college students, surely I saw the value in alienation. One medical philosopher asked what it would mean to prescribe Prozac to Sisyphus, condemned to roll his boulder up the hill.

That variant of the what if question sent me to Albert Camus’s essay on Sisyphus, where I confirmed what I thought I had remembered — that in Camus’s reading, Sisyphus, the existential hero, remains upbeat despite the futility of his task. The gods intend for Sisyphus to suffer. His rebellion, his fidelity to self, rests on the refusal to be worn down. Sisyphus exemplifies resilience, in the face of full knowledge of his predicament. Camus says that joy opens our eyes to the absurd — and to our freedom. It is not only in the downhill steps that Sisyphus triumphs over his punishment: ‘’The struggle itself toward the heights is enough to fill a man’s heart. One must imagine Sisyphus happy.'’

I came to suspect that it was the automatic pairing of depth and depression that made the medical philosopher propose Sisyphus as a candidate for mood enhancement. We forget that alienation can be paired with elation, that optimism is a form of awareness. I wanted to reclaim Sisyphus, to set his image on the poster for the campaign against depression.

Once we take seriously the notion that depression is a disease like any other, we will want to begin our discussion of alienation by asking diagnostic questions. Perhaps this sense of dislocation signals an apt response to circumstance, but that one points to an episode of an illness. Aware of the extent and effects of mood disorder, we may still value alienation — and ambivalence and anomie and the other uncomfortable traits that sometimes express perspective and sometimes attach to mental illness. But we are likely to assess them warily, concerned that they may be precursors or residual symptoms of major depression.

How far does our jaundiced view reach? Surely the label ‘’disease'’ does not apply to the melancholic or depressive temperament? And of course, it does not. People can be pessimistic and lethargic, brooding and cautious, without ever falling ill in any way. But still, it seemed to me in my years of immersion that depression casts a long shadow. Though I had never viewed it as pathology, even Woody Allen-style neurosis had now been stripped of some of its charm — of any implicit claim, say, of superiority. The cachet attaching to tuberculosis diminished as science clarified the cause of the illness, and as treatment became first possible and then routine. Depression may follow the same path. As it does, we may find that heroic melancholy is no more.

In time, I came to think of the van Gogh question in a different light, merging it with the eradication question. What sort of art would be meaningful or moving in a society free of depression? Boldness and humor — broad or sly — might gain in status. Or not. A society that could guarantee the resilience of mind and brain might favor operatic art and literature. Freedom from depression would make the world safe for high neurotics, virtuosi of empathy, emotional bungee-jumpers. It would make the world safe for van Gogh.

Depression is not a perspective. It is a disease. Resisting that claim, we may ask: Seeing cruelty, suffering and death — shouldn’t a person be depressed? There are circumstances, like the Holocaust, in which depression might seem justified for every victim or observer. Awareness of the ubiquity of horror is the modern condition, our condition.

But then, depression is not universal, even in terrible times. Though prone to mood disorder, the great Italian writer Primo Levi was not depressed in his months at Auschwitz. I have treated a handful of patients who survived horrors arising from war or political repression. They came to depression years after enduring extreme privation. Typically, such a person will say: ‘’I don’t understand it. I went through — ‘’ and here he will name one of the shameful events of our time. ‘’I lived through that, and in all those months, I never felt this.'’ This refers to the relentless bleakness of depression, the self as hollow shell. To see the worst things a person can see is one experience; to suffer mood disorder is another. It is depression — and not resistance to it or recovery from it — that diminishes the self.

Beset by great evil, a person can be wise, observant and disillusioned and yet not depressed. Resilience confers its own measure of insight. We should have no trouble admiring what we do admire — depth, complexity, aesthetic brilliance — and standing foursquare against depression.

Peter D. Kramer is a clinical professor of psychiatry at Brown University and the author of ‘’Listening to Prozac.'’ This essay is adapted from his book ‘’Against Depression,'’ which Viking will publish next month.

Man Catches Fire During Surgery

Man Catches Fire During Surgery - Yahoo! News

Seattle police launched an investigation on Friday to determine how a patient undergoing emergency heart surgery caught on fire at a local hospital in 2003.

The male patient, who was not identified, went up in flames after alcohol poured on his skin was ignited by a surgical instrument.

The patient died after the surgery but that was due to heart failure and not the fire, said Dr. Robert Caplan, medical quality director of Virginia Mason.

Caplan said fires are known to occur in operating rooms although they were extremely rare.

The two-year-old incident became publicly known after an anonymous letter sent to the media mentioned it as a sign of unsafe health care at the hospital, and said the patient burned to death.

Caplan strongly disputed its contents. “That letter is factually incorrect,” he said.

Pessimism Raises Dementia Risk, Study Finds

Category: Dementia, Depression

Pessimism Raises Dementia Risk, Study Finds - Yahoo! News

Pessimistic, anxious and depressed people may have a higher risk of dementia, U.S. researchers reported on Thursday.

A study of a group of 3,500 people showed that those who scored high for pessimism on a standardized personality test had a 30 percent increased risk of developing dementia 30 to 40 years later.

Those scoring very high on both anxiety and pessimism scales had a 40 percent higher risk, the study showed.

“There appears to be a dose-response pattern, i.e., the higher the scores, the higher the risk of dementia,” Dr. Yonas Geda, a neuropsychiatrist at the Mayo Clinic in Rochester, Minnesota who led the study, said in a statement.

Geda and colleagues looked at the medical records of 3,500 men and women who lived near the clinic between 1962 and 1965.

They all took the Minnesota Multiphasic Personality Inventory, a standard personality and life experience test, Geda’s team told a meeting of the
American Academy of Neurology in Miami.

In 2004 the team interviewed the participants or family members.

Those who scored higher for anxiety and pessimism on the test were more likely, as a group, to have developed dementia by 2004, including
Alzheimer’s disease and vascular dementia.

This did not mean a person who is pessimistic could assume he or she has a higher risk of developing dementia.

“One has to be cautious in interpreting a study like this,” Geda said.

“One cannot make a leap from group level data to the individual. Certainly the last thing you want to do is to say, ‘Well, I am a pessimist; thus, I am doomed to develop dementia 20 or 30 years later,’ because this may end up becoming a self-fulfilling prophecy.”

And there is not any specific way to prevent dementia, although many studies have shown that a healthy diet, exercise, keeping active in other ways, doing puzzles and other activities lower the risk.

Yahoo! News - On April 15, headaches and unpleasant surprises

In 1986, President Ronald Reagan signed into law the last significant simplification of the tax code. Since then, succeeding presidents and Congresses have messed it up again with layers of complexity.

Anyone who saw this coming could have made killing. A $5,000 investment in the stock of tax-return preparer H&R Block in the fall of 1986 would (with dividends reinvested) be worth more than $170,000 today.

But for those not inclined to put their money where their cynicism is, the increasing complexity of the tax code has made for nothing but misery. The code has become so complicated that it is best seen as a tax in itself. Call it the complexity tax.

On top of the tax paid on income and capital gains, we pay a cost - in dollars or in hours - because lawmakers like to accommodate lobbyists seeking deductions, exemptions and credits. Some of the ways the public pays:

• Help! Help! Sixty-one percent of taxpayers have been driven into the clutches of tax-preparation services, according to the National Taxpayers Union. That’s up from 38% in 1980 and 46% in 1986.

•Are we done yet? Taxpayers and their accountants will spend an average of 13 hours on their Form 1040s this year, up from nine hours 15 years ago. They will spend almost four hours on 1040EZs, up from one hour in 1990.

• The cost of compliance. Individuals and companies spend about 6.5 billion hours filing their taxes, according to the Government Accountability Office. Estimates of the cost to the economy run from $125 billion to $140 billion.

What makes all of this anguish and expense more remarkable is that it comes despite the arrival of user-friendly tax preparation software such as Turbo Tax. Even these tools are no match for a monster code.

Now comes a new reform plan. President Bush has appointed former senators Connie Mack, R-Fla., and John Breaux, D-La., to chair a commission on simplifying the tax code. It’s set to hold its seventh hearing on Monday.

Taxpayers would be well served if the commission could persuade Congress to fix the code. But given the track record of tax reform, they might want to hedge their enthusiasm. In fact, perhaps they should go out and buy shares of H&R Block.

Americans Spend 6.6 Billion Hours on Taxes

Category: Politics, Stress

Yahoo! News - Americans Spend 6.6 Billion Hours on Taxes
By MARY DALRYMPLE, AP Tax Writer

WASHINGTON - People scurrying to meet tonight’s tax deadline might consider this: It’s taking you and your fellow Americans 6.6 billion hours to do all that paperwork. The basic tax return — the Form 1040 filed by most people every year — accounts for 1.6 billion hours.

The Internal Revenue Service furnished those statistics to the White House budget office, which keeps tabs on the government’s bureaucratic demands. The budget office notes that tax work “towers over the entire paperwork burden for the rest of the federal government” and accounts for some 80 percent.

“If anything, those numbers are probably understated,” said David Keating, president of the National Taxpayers Union, which reports annually on the increasing complexity and demands of tax returns.

“A lot more of the cost is just planning to do the tax-smart thing. That can actually take a lot more time than reporting what you’ve done,” he said.

Tax returns must be postmarked by midnight tonight.

Sensitive to the demands that tax laws put on weary taxpayers, the IRS has seven people working full time to reduce the anguish for filers. The IRS Office of Taxpayer Burden Reduction looks for requirements that can be streamlined, reduced or eliminated under the law.

“We’re trying to reduce unnecessary burden,” said Michael Chesman, the office director.

Some of the burden cannot be avoided because it is a requirement of the tax laws. By attacking unnecessary burden, the office has shaved more than 200 million hours from tax paperwork since the office was created in 2001.

Chesman said the office plans next year to simplify the process for requesting an extension. The idea is to replace the current four-month, and subsequent two-month, deadline extensions with one simpler and automatic six-month extension.

Small changes can make a big difference. Letting more people use the simpler 1040 forms trimmed 5 million hours off the paperwork, for example. But the improvements are often swamped by the burdens associated with new tax laws. President Bush has enacted tax changes every year he has been in office.

For individuals wondering how long they will spend on tax forms, the taxpayers’ group said it takes an estimated 26 hours and 48 minutes to prepare the Form 1040 and its most common supporting schedules. That includes keeping records, learning the law, preparing forms, copying and mailing.

That actually is less than last year, when taxpayers could have expected to spend 28 hours and 30 minutes on the same forms.

Tax preparation software has made the task more manageable for many. Where the IRS estimates it takes 13 hours to fill out the Form 1040 by hand, Julie Miller, spokeswoman for Intuit, said its TurboTax software can do the same work in two hours to four hours.

Kathy Burlison, director of tax implementation at H&R Block, said software makes individuals and paid preparers more confident they have not missed something. It also makes mistakes much easier to fix.

Nevertheless, the forms are not just a drain on people’s free time, but on the productivity of the country, Keating said.

“That’s a huge, dead weight burden, trying to discern the tax code, what it rewards most,” he said. “If we turn the nation into a paper-shuffling, law-figuring-out country, no one actually gets anything done.”

Variety of Activities May Lower Dementia Risk - Study

Category: Dementia

ABC News: Variety of Activities May Lower Dementia Risk - Study

Apr 14, 2005 — WASHINGTON (Reuters) - A variety of activities like exercise, household chores and even dancing, can help people avoid Alzheimer’s and other forms of dementia, U.S. researchers said on Thursday.

They found that variety was more important for preventing dementia than total calories burned in exercise and other physical activities.

“We don’t yet know why this association exists or what causes it,” said Dr. Constantine Lyketsos, a professor of psychiatry and behavioral sciences at Johns Hopkins University.

“It could well be that maintaining a variety of activities keeps more parts of the brain active, or that this variety reflects better engagement in both physical and social activities,” he added in a statement.

The study included 3,375 men and women over the age of 64 who did not have dementia when the program began.

Writing in the American Journal of Epidemiology, Lyketsos and colleagues said each volunteer answered questions about the frequency and duration of physical activities such as walking, household chores, gardening, dancing, bowling or swimming.

Researchers then created an activity index, and considered other factors such as age, gender, education level, ethnicity, smoking and alcohol use.

Over the next 5 years, 480 people developed dementia. Of those, only 84 who listed four or more activities developed dementia, as opposed to 130 who listed one activity or none.

The association held true for all types of dementia, including Alzheimer’s disease and vascular dementia.

The study also took into consideration what type of APOE gene people had. APOE, or apolipoprotein-E, is related to cholesterol metabolism and people with one particular variant of this gene called APOE-4 have a higher risk of Alzheimer’s.

And in the study, exercise and other activities did not protect people with APOE-4.

An estimated 4.5 million Americans have Alzheimer’s disease, the most common form of dementia, and this number is projected to reach 16 million by 2050, as the population ages, unless ways are found to prevent it.

Wild Blueberry Compounds May Work Against All Stages of Cancer

Wild Blueberry Compounds May Work Against All Stages of Cancer

Thursday April 14, 9:52 am ET

PORTLAND, Maine, April 14 /PRNewswire/ — New research findings concluded that Wild Blueberry compounds have the potential to attack all stages of cancer — initiation, promotion and proliferation. (Source: Journal of Food Science, 70(3):S159-S166, 2005.) According to the study, different types of Wild Blueberry phenolic compounds are active during different stages of cancer, resulting in a broad spectrum of potential cancer-fighting benefits.

“Wild Blueberry compounds offer a multi-pronged attack against cancer,” said Dr. Mary Ann Lila, Ph.D., lead researcher from the Department of Natural Resources and Environmental Sciences, University of Illinois at Urbana- Champaign. Other collaborators include John Pezzuto, Ph.D., from the School of Pharmacy, Purdue University, and Muriel Cuendet and Young-Hwa Kang from the Department of Medicinal Chemistry and Pharmacognosy, University of Illinois at Chicago.

According to Dr. Lila, cancer begins as a result of an assault on cells by free radicals leading to oxidative stress or inflammation. “We’re investigating the potential of natural antioxidants like those found in Wild Blueberries to combat the free radical attack in the body,” said Dr. Lila. “What makes it so intriguing is that in addition to free radical scavenging, Wild Blueberries contain other natural components that are simultaneously inhibiting cancer-promoting enzymes and blocking the growth of tumor cells. How these compounds get into the body and the mechanics of how they work is the next frontier.”

According to Dr. Lila, these results build on previous work done at the University of Illinois at Urbana-Champaign, which demonstrated the positive effect of Wild Blueberry proanthocyanidins or condensed tannins on the promotion stage of cancer. (Journal of Agricultural and Food Chemistry, 52:6433-6442, 2004.)

Nature’s #1 Antioxidant Fruit(TM)

According to Susan Davis, MS, RD, Nutrition Advisor to the Wild Blueberry Association of North America, Dr. Lila’s work expands on the importance of Wild Blueberries in helping fend off diseases of aging, like cancer. “Dr. Lila’s investigation of specific phytochemicals indicates that different compounds are attacking cancer cells at different stages,” said Davis. “This underscores the complexity of whole foods and the importance of eating fruits like Wild Blueberries more regularly.”

Davis noted that recent USDA research findings using the Oxygen Radical Absorbance Capacity (ORAC) measure ranked Wild Blueberries highest in antioxidant capacity per serving, compared with more than 20 other fruits. The study showed that a one-cup serving of Wild Blueberries had more antioxidant capacity than a serving of cranberries, strawberries, raspberries, apples, and even cultivated blueberries. (Journal of Agricultural and Food Chemistry, 52:4026-4037, 2004.)

Antioxidants are important in terms of their ability to protect against oxidative cell damage that can lead to conditions like Alzheimer’s disease, cancer and heart disease — conditions also linked with chronic inflammation. The antioxidant and anti-inflammatory effects of blue-purple foods like Wild Blueberries may have the potential to help prevent these diseases.

Electromagnets provide rays of hope for people with depression

Category: Depression

The Seattle Times: Electromagnets provide rays of hope for people with depression

By Nick Perry
Seattle Times staff reporter

Robert Miskimon’s list of treatments for depression reads like a clinician’s almanac.

During his first descent into darkness at age 17, doctors repeatedly injected him with enough insulin to induce a coma, then revived him with glucose, a once-popular treatment called insulin shock therapy. Later came psychotherapy. In the 1990s he tried new wonder drugs such as Prozac and Zoloft.

Each new treatment helped for a while, but then the benefits waned, said Miskimon, 61. The Vashon Island writer remains most enthusiastic about an experimental treatment he first tried two years ago: transcranial magnetic stimulation, or TMS. He said it immediately helped him sleep, eat and feel better.

“It’s the difference between feeling life is hopeless, pointless and futile to, for example, experiencing joy at the sight of an eagle outside my home or the thrill of my daughter doing very well at nursing school,” he said. “To be free from the pervasive gloom and darkness is a wonderful thing. It’s the freedom to have gradations of feelings.”

Transcranial magnetic stimulation uses powerful electromagnets to stimulate electricity inside the brain. What may sound like science fiction has gained respect in the scientific community, with several small studies showing beneficial results.
Now the National Institute of Mental Health has launched the most extensive study yet: a $7 million, four-year federally funded program to track 240 patients. The University of Washington is one of four sites tracking the patients, with the first of 60 due to begin treatment at Harborview Medical Center this month.

Although TMS has not been approved for use in the United States, it is being used in Canada. Should it eventually get the nod of the federal Food and Drug Administration, it would offer hope for thousands of patients who can’t tolerate antidepressant drugs or who don’t respond to them.

The roots of TMS can be traced to the 1930s, when a Hungarian psychiatrist first used electricity to jolt a patient’s brain into a seizure, a controversial procedure that became known as electric shock treatment. Now called electroconvulsive therapy, it remains an effective last resort for many severely depressed patients.

But the problem with inducing a seizure is that it often causes short-term memory loss and confusion. Proponents of TMS believe many patients could benefit from a gentler approach.

TMS typically involves a patient sitting in a chair for 30 to 40 minutes. A doctor rests a coil on the patient’s head, then turns on a powerful electromagnet.

The machinery sends 10 strong, short magnetic pulses every second to a particular point in the brain, stimulating electrical currents. Regular magnets, like those on your fridge, create a constant magnetic pull and won’t stimulate electricity in the same way.

One potential advantage of magnetism is that it effortlessly penetrates the skull, unlike the electrical approach which forces a current through skin and bone. During TMS treatments, patients typically feel little.

“You sit in a nice easy chair with a pad on your scalp and there is a little click and a little buzz and that’s it,” said Jim Kjeldsen, a 56-year-old journalist from near La Conner, Skagit County, who has tried experimental TMS. “It’s a bit of a problem sitting there for half an hour and staying awake.”

The magnet is usually focused on the left prefrontal cortex — a part of the brain thought to play a key role in controlling mood, and which studies show is often less active in people suffering depression.

What happens next is less clear.

According to Dr. Mark George, a pioneer of the treatment, the magnet stimulates or “tickles” the cortex, which in turn sends electric signals to the central limbic system, a more ancient part of the brain also associated with mood control.

George believes this increased electrical activity changes the brain’s chemistry, probably by increasing levels of neurotransmitters such as serotonin and dopamine. That helps elevate mood.

Other people theorize that the mental discord of depression may manifest in a physical way that is comparable to arrhythmia. That theory has TMS acting as a kind of pacemaker to better balance electrical activity, especially between the left and right sides of the brain.

But nobody really knows how TMS may work because scientists have yet to figure out all the intricacies of the brain.

A TMS patient typically gets one treatment per day, five days a week, for three to six weeks. Many proponents believe that an initial course of treatment can lift patients from a depressive episode and that later “maintenance” treatments can keep them from slipping back. That theory will be put to the test in the new study.

George, a psychiatry and neurology professor at the Medical University of South Carolina, began experimenting with TMS in the mid-1990s after finding inspiration while riding an elevator in a London research building. A bubbly man told him that a scientist just made his thumb jerk by putting a magnet against his head.

Noting the man’s animation, George wondered if magnets could be used to directly influence mood control. But the idea wasn’t embraced by the medical community, which had long accepted seizures as a vital part of any direct physical intervention in depression.

“When I began this a decade ago, these ideas were heretical,” George said. “Heretical and anathema.”

Years of failed therapies
Miskimon said he was at boarding school in 1961 when his first bout of depression struck. A good student, he became increasingly agitated and felt he was losing touch with his own body and the world around him. He all but stopped eating, losing 30 pounds and becoming emaciated. He was hospitalized for three months, regularly receiving the insulin-shock treatments.

In the years since, Miskimon tried different therapies and also turned to alcohol, which he hasn’t touched now for 20 years. Nothing worked long term. Miskimon learned to struggle through life with recurring bouts of depression, which seemed, he said, to arrive without warning and in no particular pattern.

Kjeldsen has also lived with depression since he was a teen. Particularly bad bouts seem to strike once every eight or nine years, he said.

“Not knowing if you will ever come out of this black hole is the worst thing about it,” Kjeldsen said. “It’s like a huge weight pressing down on you. You don’t get joy out of anything, and you have to map out every move all day long, because the automatic reflexes that keep you motivated are not there.”

Both Kjeldsen and Miskimon became patients in early TMS clinical trials overseen by Dr. David Avery, a UW professor and the director of inpatient psychiatry at Harborview Medical Center. Avery, another of the treatment’s pioneers, is overseeing the UW part of the new trial.

Kjeldsen said he was skeptical about TMS before the early trials but soon became a believer.

“At the end of the second treatment, I walked out of the building and everything looked a lot brighter, even the sky looked brighter,” he said.

He added that he’s not interested in trying electroconvulsive therapy (ECT), which he believes may cause some brain damage.

“It’s nothing I would like to do. I really like my brain cells, even though they play up,” he joked.

The new TMS trial is not only bigger, it is more nuanced than previous trials, which have administered a single, standard treatment. This time, patients will have their brain structure mapped so doctors can more accurately focus the magnetic pulses in the correct location. And the number of sessions a subject receives will depend on the response to each treatment.

Half the participants will be part of a control group receiving sham treatments — though later they will have the option of getting the real treatment.

Offered in Vancouver, B.C.
While transcranial magnetic stimulation is not approved in the U.S., one TMS device has been approved in Canada since 2002. A group called Mindcare Centres offers the treatment at clinics in Vancouver, B.C., and Toronto.

Iain Glass, Mindcare president and CEO, said the clinics have treated about 170 people. That includes about 60 from the Seattle area who make up a large slice of the Vancouver business.

A course at Mindcare typically involves 20 treatments spread over two weeks at a cost of $4,000 (U.S.). The treatment is not covered by most U.S. health insurers.

“We tend to treat really, really tough cases,” Glass said.

He said the average patient age is 48, and most have lived with depression since they were teenagers. Many have tried medication for years without much success, he said. People who try TMS tend to either respond “profoundly” or not at all, he added.

“It’s wildly exciting,” Glass said. “There are a lot of people for whom the system has failed, and we are giving them their lives back.”

Glass has big ambitions for the U.S. He said he wants to open 50 to 55 clinics here — if and when the FDA gives approval.

Until then, sufferers here will need to find other options. Miskimon said he will continue trying antidepressant drugs along with prayer and meditation.

“I think it would be a tremendous thing to be available,” Miskimon said of TMS. “I think of it as having the benefits of ECT without any of the drawbacks.”

“It’s a kinder, gentler approach to sanity.”

Antioxidant-rich diets reduce brain damage from stroke, new preclinical study suggests

Antioxidant-rich diets reduce brain damage from stroke, new preclinical study suggests

Tampa, FL (April 12, 2005) — Your mother was right. Eat your fruits and veggies — they’re good for you!

And if that’s not reason enough, a new study suggests antioxidant-rich fruits and vegetables may limit brain damage from stroke and other neurological disorders. The study, conducted by researchers at the University of South Florida College of Medicine, James A. Haley Veterans’ Hospital and the National Institute on Drug Abuse, is posted online in the May 2005 issue of the journal Experimental Neurology.

USF/VA neuroscientist Paula Bickford, PhD, and colleagues found that rats fed diets preventatively enriched with blueberries, spinach or an algae known as spirulina experienced less brain cell loss and improved recovery of movement following a stroke.

“This study is how USF is advancing the field of brain health at the national level,” said Stephen Klasko, MD, MBA, dean of the USF College of Medicine and vice president for Health Sciences.

The study builds upon previous USF/VA research showing that diets enriched with blueberries, spinach or spirulina reversed normal age-related declines in memory and learning in old rats.

“I was amazed at the extent of neuroprotection these antioxidant-rich diets provided,” said Dr. Bickford, a researcher at the USF Center for Aging and Brain Repair and James A. Haley Veterans’ Hospital. “The size of the stroke was 50 to 75 percent less in rats treated with diets supplemented with blueberries, spinach or spirulina before the stroke.”

Antioxidant and anti-inflammatory substances in these fruits and vegetables may somehow reduce the nerve cell injury and death triggered by a stroke, the researchers suggest. “The clinical implication is that increasing fruit and vegetable consumption may make a difference in the severity of a stroke,” Dr. Bickford said. “It could be a readily available, inexpensive and relatively safe way to benefit stroke patients.”

The researchers studied four groups of rats, all fed equal amounts of food for one month. One group was fed rat chow supplemented with blueberries, a second group chow with spinach, and the third chow with spirulina. The control (untreated) group ate chow only.

After four weeks, an ischemic stroke with reperfusion was induced in the rats. An ischemic stroke occurs when a blood clot cuts off the oxygen supply to the brain like the kink in a hose cuts off water flow. Then, later, the clot is released and blood flow returns, which is known as reperfusion.

The size of the stroke in the rats fed blueberry or spinach supplements was half that seen in the brains of untreated rats. Rats fed spirulina-enriched diets had stroke lesions 75 percent smaller than their untreated counterparts. In addition, rats pretreated with the blueberry, spinach or spirulina diets showed greater increases in poststroke movement than the control group.

All the supplemented diets were rich in antioxidants, which scientists say may counteract the burst of free radicals involved in the cascade of brain cell death triggered by an ischemic stroke. An excess of free radicals can damage cellular lipids, proteins and DNA.

The supplemented diets also contained anti-inflammatory substances that may help reduce inflammation-induced injury following a stroke, Dr. Bickford said. When a stroke occurs, immune cells in the brain mount an inflammatory response – rushing to the site of injury to clear away the dead and dying cells. As a result, nearby healthy nerve cells may suffer collateral damage much the same way firefighters breaking into an apartment to put out a fire in one room may inadvertently cause damage to other rooms.

Teasing out just which beneficial chemicals contained in the blueberries and leafy greens might be reproduced therapeutically in pill form is difficult, Dr. Bickford said. “Whole foods contain multiple nutrients, so there are many different ways these diets could be protecting the brain. From a scientific perspective, it’s a package deal.”

Dr. Bickford’s team is investigating whether rats treated with antioxidant-rich diets following strokes will experience improved recovery. The researchers also plan to study whether combinations of the diets might provide even greater protection against stroke damage than one diet alone.

The study was supported by grants from the National Institute on Drug Abuse and the Veterans Administration.

Older Hearts Benefit from Fish, Soy Oil

MedlinePlus: Older Hearts Benefit from Fish, Soy Oil

NEW YORK (Reuters Health) - In elderly people, omega-3 fatty acids contained in fish and soy oil increase a measure of heart-healthiness called heart rate variability, a small study indicates.

Taking a daily fish or soy oil supplement may therefore reduce the risk of developing irregular heart rhythm or succumbing to sudden cardiac death.

Lead investigator Dr. Fernando Holguin, at Emory University School of Medicine in Atlanta, and colleagues followed 52 people aged 60 or older who were randomly assigned to take one of the oil supplements, given as 1-gram capsules twice daily for 6 months.

The heart rate variability of the participants was measured every other day.

As the team reports in the medical journal Chest, fish oil supplementation increased average total variability from 3.26 units prior to supplementation to 3.54 afterwards. Soy oil increased the measure from 3.16 to 3.28.

“Our study group showed improvements in heart function in as little as 2 weeks,” Holguin comments in a press release.

Some participants reported discomfort with the supplements. Belching was reported by 41 percent in the fish oil group and 16 percent in the soy oil group. Corresponding rates for nausea were 12.5 percent and 8 percent.

Holguin’s group recommends omega-3 fatty acids supplements derived from either soy oil or fish oil “in conjunction with other factors known to increase heart rate variability such as exercise, weight loss, stress reduction, and restoration of normal sleep” to improve heart health.

Potassium, in Any Form, Lowers Blood Pressure

MedlinePlus: Potassium, in Any Form, Lowers Blood Pressure

NEW YORK (Reuters Health) - Potassium citrate has similar blood pressure-lowering effects as the best-studied potassium compound, potassium chloride, according to a UK study

In comments to Reuters Health, Dr. Graham A. MacGregor said the important role of potassium in regulating blood pressure has been demonstrated in carefully controlled studies using potassium chloride and inactive “placebo” tablets. But it has not been clear, until now, how far other potassium salts lowered blood pressure.

“These results support other evidence for an increase in potassium intake and indicate that potassium does not need to be given in the form of chloride to lower blood pressure,” MacGregor and colleagues from St. George’s Hospital Medical School in London write in the American Heart Association’s journal Hypertension.

“Increasing the consumption of foods high in potassium is likely to have the same effect on blood pressure as potassium chloride,” the researches say.

They compared the effects on blood pressure of potassium chloride or potassium citrate in 14 adults with hypertension — that is, with blood pressure readings above 140/90. The participants took one compound for 1 week, waited a week, and then took the other for a week.

Average blood pressure at the start of the study was 151/93. It fell significantly to 140/88 with potassium chloride and to 138/88 mm Hg with potassium citrate.

“Our short-term study shows that potassium citrate is as effective as potassium chloride, and this supports the evidence that the main effect of increasing fruit and vegetable intake on blood pressure is due to the increase in potassium intake,” MacGregor said.

VOA News - Stress Management as Effective as Exercise In Reducing Heart Problems

By Brian Purchiav

We all feel stressed out now and then, but for people with heart problems, stress can be deadly. Researchers found that providing training in stress management was just as effective as exercise in reducing the risk of more heart problems.

Joseph Mazzetta, participated in the study
Eighty-year-old Joseph Mazzetta is having his heart function checked, because seven years ago he had angina — oxygen wasn’t getting to his heart. “I started getting shortness of breath and a little tightness in my chest,” he said.

Today he feels much better. He was one of 134 heart patients who took part in a Duke University Medical Center study. Researchers divided the patients into three groups. One got exercise training, which was Joseph’s group. Another received stress management training, and the third group got usual medical care. The training programs lasted four months, to see if exercise or training reduced stress.

Research findings are published in the Journal of the American Medical Association (JAMA)
The findings appear in JAMA, the Journal of the American Medical Association. The author of the study is Dr. James Blumenthal. “Those patients who underwent the stress management or the exercise training experienced significant improvements in levels of depression and overall psychological distress, and not only did they experience those psychological benefits, but they experienced physical benefits as well.”

When patients experienced mental stress, exercise and stress management training were equally effective at reducing ischemia, which is when narrowed blood vessels prevent blood from flowing to the heart. But people who got stress management training saw added benefits improved blood vessel health and the way the body handles surges in blood pressure.

Dr. James Blumenthal, Duke University Medical Center
Dr. Blumenthal says, “We taught them what stress was, how to recognize it, and then we taught them strategies as to how to reduce their stress levels.” He adds that more physicians should recommend exercise or stress management training for their heart patients. “I think they feel that medication may be sufficient. I think data from this study would indicate that exercise and stress management really add to the benefits of medical management of patients.”

Joseph Mazzetta takes three heart medications a day, and continues the exercise he started during the study. “I do it also because I want to live another day (laughs), it’s as simple as that.”

Mr. Mazzetta didn’t receive stress management training, but he says regular workouts have helped reduce his stress.

BMAA: Algae Found to Produce Potential Neurotoxin

Here’s another article on BMAA and algae. Health food and Vitamin stores usually carry a lot of algae products, I wonder if any connection to BMAA neurotoxins will be found?

Scientific American: Algae Found to Produce Potential Neurotoxin

Algae Found to Produce Potential Neurotoxin

A variety of types of blue-green algae all produce the same molecule, a potential neurotoxin, a new report suggests. The results, published online this week by the Proceedings of the National Academy of Sciences, represent the first time that unrelated species of cyanobacteria have been found to produce the same potentially hazardous substance.

Cyanobacteria can produce a wide range of molecules that are harmful to humans, but which species generate which compounds has so far been quite unpredictable. Paul Alan Cox of the National Tropical Botanical Garden in Hawaii and his colleagues studied five different morphological sections of cyanobacteria, as well as cyanobacterial symbionts taken from lichen and other plant species. They discovered that 95 percent of all genera of cyanobacteria produce a molecule identified as BMAA, a suspected neurotoxin that has been recently detected in the brains of some Alzheimer’s sufferers. The amount of BMAA manufactured by the algal samples varied widely. The scientists thus posit that BMAA production and storage is a function of either growth conditions or life cycle stages of the bacteria.

Because of the widespread nature of cyanobacteria, the researchers suggest that it might be wise to monitor levels of BMAA in drinking water sources that contain cyanobacterial blooms. They note: “The ubiquity of cyanobacteria in terrestrial, as well as freshwater, brackish and marine environments, suggests a potential for widespread human exposure.” –Sarah Graham

MedlinePlus: Poor Blood Pressure Control Ups Stroke Risk

NEW YORK (Reuters Health) - About half of all first-time strokes in patients being treated for high blood pressure result from the pressure not being adequately controlled, Swedish researchers report. Older age, diabetes, and smoking also raise the risk of stroke in these patients.

The study, published in the medical journal Stroke, included nearly 28,000 men and women aged 45 to 73 living in Malmo.

Sixty percent of patients had high blood pressure, but only 23 percent of them were being treated. Moreover, among those receiving treatment, nearly 90 percent had pressures above recommended limits, according to Dr. Cairu Li of Malmo University Hospital and colleagues.

Two-thirds of patients with inadequately controlled blood pressure were on single-drug regimens, the researchers note, with beta-blocker type drugs being the most commonly used overall.

During follow-up, which averaged six years, 137 strokes occurred among the patients with high blood pressure. The researchers found that 45 percent of the stroke risk could be attributed to inadequately controlled blood pressure.

While there were only minor initial differences in survival between patients with controlled or poorly controlled blood pressure, these differences increased over time.

“Adequate (blood pressure) control may prevent a substantial proportion of first-ever stroke among” patients treated for high blood pressure, the researchers conclude.

NT-proBNP: Testing Elders’ Blood for Heart Disease

Testing Elders’ Blood for Heart Disease
High Levels of a Protein Could Predict Death, Heart Trouble

on Tuesday, April 05, 2005

April 5, 2005 — A blood test could help predict heart disease in older adults even after taking into account more traditional risk factors.

The key blood chemical may change with age, according to a new study in The Journal of the American Medical Association.

Could the findings lead to a new heart disease blood test for senior citizens? Perhaps, but more work is needed first, write the researchers, who included Caroline Kistorp, MD, of Denmark’s Frederiksburg University Hospital.

Heart disease is a leading cause of death for U.S. men and women. It hits older adults especially hard.

About 84% of heart disease deaths occur in people aged 65 and older, according to the American Heart Association (AHA). Similarly, about 88% of stroke deaths strike people aged 65 or older, says the AHA.

Probing the Blood to Predict Heart Trouble

In middle-aged people, high blood levels of the inflammatory marker known as C-reactive protein have been linked to heart problems. But a few decades from now, another blood marker may be more important, say Kistorp and colleagues.

For adults aged 50-89, another protein was a better predictor of heart disease than C-reactive protein, says Kistorp’s study.

The protein studied was called NT-proBNP. Besides beating C-reactive protein as a heart disease predictor, it also surpassed another marker of heart disease — urine protein levels.

Tracking Heart Disease

Results came from 626 people in Copenhagen. Virtually all were white, which is one reason why Kistorp’s team says further, more diverse tests are needed.

At the study’s start, none had heart or kidney failure, and 537 had no history of heart disease. The participants gave blood and urine samples for screening and were followed for five years.

During the study, 94 people died of any cause and 65 had a first major cardiovascular “event.” Those included a nonfatal heart attack, stroke, heart failure, chest pain (unstable angina), coronary heart disease, and transient ischemic attacks (ministroke).

Participants with the highest blood levels of NT-proBNP were at higher risk of heart disease deaths and heart problems, including heart attack and stroke, than those with the lowest levels.

The increased risk of heart disease continued to exist even after the researchers took into account traditional risk factors for heart disease, such as smoking and being overweight.

Earlier Findings

In 2003, other researchers reported that another inflammatory marker, interleukin-6, was a better predictor of heart disease, stroke, and heart failure in a three-year study of 2,225 people in their 70s.

That study didn’t cover the type of protein studied here, but the researchers said they thought C-reactive protein might not be as closely tied to cardiovascular events in older people. That study appeared in the November 2003 edition of the journal Circulation.

Vigorous Activity Cuts Arthritis Disabilities

Inactivity Nearly Doubles Loss of Physical Function Among Seniors With Arthritis

April 7, 2005 — Older adults with arthritis who do their best to get regular, vigorous physical activityarthritis who do their best to get regular, vigorous physical activity have an advantage over those who are sedentary.

“Lack of regular, vigorous physical activity … almost doubled the odds of functional decline after controlling for all risk factors,” says a study in April’s issue of Arthritis & Rheumatism.

If everyone in the study had gotten enough activity, decline in physical function could have been as much as 32% lower, the researchers estimate.

“Older persons with chronic conditions need to be encouraged to participate in physical activities, regardless of their current capabilities,” they write.

Arthritis and other rheumatic conditions are the leading causes of disability in the U.S., says the study. Nearly 60% of U.S. adults aged 65 and older have arthritis, and 10% of them say their daily activities are limited, the researchers note.

Trouble With Daily Life

Arthritis can be painful, and that may understandably make some patients want to avoid physical activity.patients want to avoid physical activity. But the new study says that’s not always a great idea.

More than 5,700 people with arthritis participated. All were at least 65 years old.

At the study’s start, nearly one in five said their physical function was limited, and some 13% had trouble with activities of daily life. Almost 6% said they had trouble with two or more activities, while twice as many reported problems with three or more daily tasks.

Men, Whites More Active

Many participants said they weren’t very active, but women and minorities were more likely to fall into that category.

Women were more likely than men to say they had a hard time with daily activities.

About 68% of women said they didn’t get regular, vigorous activity, compared to 57% of men. Among minorities of either sex, the rates were 73% for blacks, 70% for Hispanics, and 63% for whites or people of other races.

After two years, 14% of at-risk participants reported declines in physical function. That included 15% of all women in the study, 18% of Hispanics, and nearly 19% of black participants.

After evaluating various potentially unhealthy behaviors, the researchers found that lack of regular, vigorous physical activity nearly doubled the risk of functional decline. Almost two-thirds of the participants did not get regular physical activity.

More Problems 2 Years Later

The biggest predictor of limitations in daily activities was lack of regular vigorous physical activity. A decline in mental skills also predicted physical limitations in daily activity.

“Function declined less frequently in persons who engaged in regular, vigorous physical activity, regardless of their baseline ability,” write the researchers, who included Dorothy Dunlop, PhD, of Northwestern University’s medical school.

In other words, being as active as possible was beneficial. Health care providers can help design a plan to do that safely.

Lack of regular physical activity is a potentially modifiable risk factor which could substantially reduce functional decline and health care cost, they conclude.

Mediterranean Diet Linked to Longer Life

Researchers Recommend Diet Low in Meat and Dairy, High in Fruits and Veggies

By Salynn Boyles

on Thursday, April 07, 2005

April 7, 2005 — There is more evidence that eating like a villager on the Isle of Crete can help you live longer.

A study examining eating patterns in nine European countries found that people who ate a traditional Mediterranean diet lived longerpeople who ate a traditional Mediterranean diet lived longer than those who didn’t.

Researchers say a healthy man of 60 who follows the diet, which is rich in fruits and vegetables and low in meat and dairy, can expect to live a year longer than a man of the same age who doesn’t follow the diet.

“A year may not sound like much to some people,” study researcher Dimitrios Trichopoulos, MD, PhD, tells WebMD. “But I’m in my mid 60s, and it sounds pretty good to me.”

Living to 100

Physiologist Ancel Keys was both the world’s best-known champion of the Mediterranean diet and its best advertisement.

Keys was the first to notice, more than half a century ago, that heart disease was rare in Mediterranean areas like Greece and southern Italy, where olive oilolive oil and red winered wine were dietary staples and people ate plenty of fruits and vegetables.

Keys died late last year at the age of 100, still active and doing nutrition research until the last few years of his life.

In an interview with WebMD in 2000, he lamented the fact that the typical meat, cheese, and pasta-heavy dishes Americans encounter in Italian restaurants have little in common with traditional Mediterranean fare.

“The Mediterranean diet was nearly vegetarian, with fish and very little meat, and was rich in green vegetables,” he said, adding that something got lost in the translation from Italy to the U.S. “They may call it Italian, but it’s very different from the food we studied.”

Eating Mediterranean

The newly published study involved more than 74,000 healthy men and women aged 60 and older living in Denmark, France, Germany, Greece, Italy, the Netherlands, Spain, Sweden, and the United Kingdom.

Study participants were asked about their diets, medical and smoking histories, exercise patterns, and other relevant health information. Researchers measured how closely they stuck to a Mediterranean-style diet using a special scale developed by the researchers. The findings are reported in the April 8 issue of the British Medical Journal.

Eating a Mediterranean diet was linked to a longer life. The largest association was seen in Greece and southern Italy, where people stuck more closely to the diet.

Mediterranean Diet: More Than Olive Oil

Trichopoulos says there is no single component of the Mediterranean diet that holds the key to longer life. Though the mantra of Mediterranean eating could be “olive oil good, saturated fats bad,” there is more to it than that.there is more to it than that.

“In this case, the total is better than the sum of the parts,” he says. “You can’t point to one thing and say that is what does it.”

People who follow traditional Mediterranean diets:

* Eat mostly plant foods, including fruits, vegetables, beans, whole grains, and nuts.
* Eat fish often but eat other animal-based foods such as red meat, poultry, and dairy sparingly.
* Drink alcohol in moderation — no more than one drink a day for women and no more than two drinks a day for men. While many believe that red wine offers health advantages over other forms of alcohol, Trichopoulos says that is still not clear. One drink equals 1.5 ounces of liquor (whiskey, gin, vodka, etc.), 5 ounces of wine, or 12 ounces of beer.
* Don’t limit fat consumption, as long as fats are derived from plants, not animals, and are not overly refined. Trichopoulos says olive oil is the best fat, but canola and soybean oils are also good.

Going to Extremes

Trichopoulos says the current mania for low-carbohydrate eating in the U.S. incorporates some elements of Mediterranean eating but not others.

“Americans tend to go to extremes when it comes to eating, and right now they hate carbohydrates and love protein,” he says. “Lowering carbohydrates is probably a good thing, but too much meat-based protein is not.”

Nutrition researcher Alice Lichtenstein, DSc, is a strong proponent of Mediterranean eating. But she worries that people will lose sight of the fact that there is more to good health than what you eat.

“Two-thirds of Americans are overweight or obese,” she says. “If everyone adopted this diet but did not change anything else, it is unlikely that they would reap the benefits.”

In other words, getting regular exercise and limiting calories, no matter what form they come in, is just as important as following a particular diet.

“There is no simple fix,” she says. “You really have to think about the whole package. Not just what you are eating, but how much you are eating and whether you are moving. There are no shortcuts to good health.”

High Blood Pressure Common in the Overweight

High Blood Pressure Common in the Overweight

Obese patients often have increased blood pressure, researchers report. Also, many do not experience a nighttime dip in blood pressure as occurs in normal-weight individuals, and this could lead to heart damage.

Dr. Vasilios Kotsis from the University of Mississippi Medical Center in Jackson and colleagues studied the relationship between body mass index

Only 35 patients were underweight, whereas 1,057 were normal weight, 1,299 were overweight, and 825 were obese. The subjects wore a monitor to record their blood pressure over a 24-hour period.

Blood pressure increased significantly with increasing BMI, the team reports in the American Heart Association‘s journal Hypertension.

“Obese individuals had increased 24-hour, daytime and nighttime blood pressure levels compared to non-obese individuals,” Kotsis commented to Reuters Health. Moreover, blood pressures during the night were more likely to be as high as during the day in overweight and obese individuals.

Obesity-induced hypertension is “one of the most significant” conditions related obesity, Kotsis noted.

“Primary care doctors must focus on obesity-induced hypertension in order to prevent future cardiovascular complications such as heart failure in their obese patients,” he said. “Body weight reduction, lifestyle modifications and antihypertensive treatment could reduce obese patients‘ cardiovascular risk.”

Exercise, Stress Management Show Physiological Benefits for Heart Patients

|| DukeMedNews || Exercise, Stress Management Show Physiological Benefits for Heart Patients

DURHAM, N.C. — Behavior modification techniques such as exercise and stress management can not only reduce the levels of depression and distress in heart patients, but can also improve physiological markers of cardiovascular health, according to the results of a randomized controlled trial conducted by Duke University Medical Center researchers.

According to the research team, this may be the first randomized trial to demonstrate that a non-pharmaceutical approach can have positive effects on such physiological determinants of cardiovascular health as blood flow to heart, the responsiveness of the lining of blood vessels and the ability of the cardiovascular system to regulate surges in blood pressure.

“While studies have shown that psychosocial factors such as depression, stress and anxiety place heart patients at a much greater risk of suffering future cardiac events or dying, few have looked at the effects of modifying psychosocial factors,” said Duke medical psychologist James Blumenthal, Ph.D., lead author of a study appearing in the April 6, 2005 issue of the Journal of the American Medical Association. The trial was supported by a $4.3 million grant from the National Institutes of Health.

“Our results suggest that exercise and stress management training offer considerable promise for patients with heart disease by not only improving psychosocial functioning and reactions to mental and physical stressors, but also by modifying important bio-markers of risk that may translate into improved clinical outcomes,” he said.

The Duke trial enrolled 134 patients with stable heart disease and randomized them to one of three groups – exercise, stress management or standard medical therapy. Patients randomized to the exercise group participated in 35 minutes of supervised aerobic exercise training three times a week for 16 weeks. Those in the stress management arm received 16 weekly 1.5-hour classes designed to help patients recognize the sources of stress in their everyday lives and to teach them strategies to respond more adaptively to those stresses.

Patients enrolled had stable heart disease, meaning they did not experience chest pain while at rest, and exhibited evidence of myocardial ischemia, or reduced blood flow to the heart, during exercise. All participants underwent a battery of psychological and physiological testing before randomization, which was repeated four months later.

One of the physiological markers studied was the endothelium, which forms the inner lining of the blood vessels and controls how the vessels reacted to changes in blood flow and pressure. The researchers took ultrasound images of the brachial artery of the arm before and after a tourniquet was applied and released to determine how the vessels responded. Healthy arteries will dilate to accommodate the increased blood flow, while diseased arteries are less responsive, the researchers said.

In these tests of flow-mediated dilation, patients who received the behavioral treatments displayed nearly a 25 percent improvement when compared to those patients who only received usual medical care.

“To our knowledge, this is the first study to show that stress management might reduce cardiovascular risk in part through beneficial effects on vascular endothelial function,” Blumenthal said. “This is a level of improvement is comparable to that achieved in drug trials. For that reason, these findings add additional support for the use of non-pharmaceutical approaches to treating patients with heart disease.”

The researchers also found that patients who received exercise training or stress management had improved baroreflex sensitivity, a phenomenon by which receptors located along the walls of blood vessels respond to changes in blood pressure. These receptors are connected to the heart by nerves, which carry the message to pump faster or slower in response to pressure changes.

“This finding is important because past studies have demonstrated that abnormally low baroreflex sensitivity has been shown to be associated with worse outcomes for patients with heart disease–improvement may produce clinical benefits,” Blumenthal said.

Additionally, the researchers measured changes in the left ventricle — the pumping chamber of the heart — during periods of both mental and physical stress. The research team used radionuclide imaging tests to identify wall motion abnormalities (WMAs). These WMAs, or areas of abnormal contractions of the left ventricle, are known indicators of ischemia.

“While there was no difference in WMA scores between the three groups during mental stress testing, among the subgroup of patients who had mental stress-induced WMAs before treatment, those in the exercise and stress management groups had lower WMA scores after treatment compared to patients in usual care.”

Other findings, which were expected, showed that patients in the exercise group had the largest improvements in such measures as exercise duration and aerobic capacity. For the psychosocial tests, the researchers found that exercise and stress management had reduced general distress and depression compared to usual care controls.

Future studies are planned to determine if stress management and exercise together have an even greater positive effect on these markers of cardiovascular health. The researchers also said further investigation is needed to reveal the biological mechanisms behind the improvements seen.

Valdoxan®: A New Approach to The Treatment of Depression

Valdoxan®: A New Approach to The Treatment of Depression

First Melatonergic Agonist Antidepressant Shows Efficacy and Tolerability Benefits Over Existing Therapies -

Valdoxan® (agomelatine), the first melatonergic (MT1 and MT2 receptor) agonist antidepressant, is an innovation in the treatment of depression with several advantages over existing treatments according to data presented during the 13th Congress of the Association of European Psychiatrists. Besides being an effective antidepressant, Valdoxan has shown particular advantages in improving the often disrupted sleep patterns of depressed patients, without affecting daytime vigilance.

“Agomelatine is an interesting and potentially very valuable antidepressant that is effective in both moderate and severe depression”, says Professor Stuart Montgomery from the Imperial College School of Medicine in London. “The new agent has a unique mode of action, improves sleep without affecting daytime alertness and its efficacy is not compromised by sexual side effects, tolerability problems or discontinuation symptoms.”

Antidepressant efficacy

The antidepressant efficacy of Valdoxan has been shown at a standard dose of 25 mg, once daily in the evening, in a dose-ranging study performed in major depressive disorder (MDD)1. In this multicentre, placebo-controlled, dose-ranging study over eight weeks, Valdoxan was shown to be an effective antidepressant at a dose of 25 mg once daily, by reducing the initial HAMD score to a similar extent to that of the SSRI paroxetine. Further studies versus placebo and comparators have confirmed the efficacy of Valdoxan in adults of all ages, including the severely depressed and elderly depressed. Results from another clinical trial presented here in Munich show that Valdoxan has a similar efficacy to the SNRI venlafaxine.

Improvements of disturbed wake-sleep cycles

“The ability to relieve sleep problems without being sedative is a key advantage for depressed patients who frequently suffer from sleep disturbances associated with their depression”, points out Christian Guilleminault, MD, from Stanford University Sleep Disorders Clinic, California.

Due to its unique pharmacological profile, Valdoxan is the only antidepressant to have a specific action on circadian rhythms, which are often imbalanced in depressed patients. By improving disturbed wake-sleep patterns, according to Dr Guilleminault, Valdoxan is able to relieve sleep complaints of depressed patients with a favourable impact on daytime vigilance.

Tolerability profile

Data presented by Professor Montgomery shows that Valdoxan provides antidepressant efficacy, but lacks typical antidepressant side effects. The new agent does not appear to impair sexual function. A study comparing Valdoxan with venlafaxine showed comparable antidepressant efficacy of both treatments, but significantly less sexual dysfunction of Valdoxan compared to the SNRI. In addition, a placebo-controlled, double-blind study comparing Valdoxan with paroxetine showed that, after one week of treatment discontinuation, no signs of discontinuation symptoms* were seen in the agomelatine group compared to significant discontinuation symptoms in the paroxetine group.2

Valdoxan was discovered and developed by Servier. The drug is currently in Phase III and a registration dossier for an indication in MDD was recently submitted to the European Regulatory Agency (EMEA).

Discontinuation symptoms occur when treatment with certain antidepressants (mainly SSRIs and SNRIs) is stopped. They can include nausea, headache, dizziness, sleep disturbances, anxiety and irritability.

Cranberry juice modulates atherosclerotic vascular dysfunction

Cranberry juice modulates atherosclerotic vascular dysfunction

Six months on cranberry juice normalizes blood vessel function-relaxation and may protect against heart disease -

San Diego (April 3, 2005) - Protection against a wide variety of diseases is among the many benefits of a diet high in whole fruits and vegetables. Cranberries over the years have been identified with preventing or ameliorating urinary tract infections and playing a positive role gum disease, ulcers and even cancer.

Recent work shows that cranberries contain naturally derived compounds (antioxidants, flavonoids, and polyphenols) that may help protect against heart disease. Researchers at the University of Wisconsin-Madison School of Veterinary Medicine studied the effects of taking cranberry juice powder regularly over six months and found a pronounced improvement in the vascular function — the ability of blood vessels to relax - in subjects with high blood cholesterol and atherosclerosis.

“Since the abnormal functioning of blood vessels is an important component of heart disease, finding ways to improve vascular function in patients with high cholesterol and atherosclerosis is critical to helping protect these patients from consequences such as heart attack or stroke,” according to lead researcher Kris Kruse-Elliott.

Taking the whole-food approach

“The value of fruits and vegetables in our diet has recently been an area of intense research and studies like this help us to understand the specific mechanisms by which the nutrients we consume can protect against heart disease,” Kruse-Elliott said. She said that the next steps are “to determine what specific components of cranberries are most important to the improvements in vascular function that we observed, exactly how they modify blood vessel relaxation, and how they can be most easily consumed as part of the diet.”

Kruse-Elliott’s collaborator, Jess Reed has been working with other foods such as pomegranates and grape seed extract, as well as whole cranberries. According to Reed, “the equivalent consumption of dried cranberries would be 4-8 servings, or 10-20 servings of cranberry juice, in order to achieve the levels in the current study. However, the point to be emphasized is that total polyphenol intake is very low in western diets and a diet rich in polyphenols would in fact give a daily intake that is equivalent to the levels in our cranberry feeding experiments.”

Kruse-Elliott added: “We’re lucky to have a unique animal model for atherosclerosis - familial hypercholesterolemic (FH) swine, whose genetic defect causes them to spontaneously develop high blood cholesterol leading to atherosclerosis and vascular dysfunction by eight months of age, very similar to the way human beings do.” She noted that the FH pigs’ blood vessels don’t function normally, such as not relaxing well, compared with normal pigs.

“However when the FH pigs were fed cranberry juice powder, made from whole cranberries, for six months their vessels acted more like normal pigs, Kruse-Elliott said. FH pigs who didn’t get cranberry juice powder had “significantly less vascular relaxation” than either normal or cranberry-fed pigs. The pigs on the CJP diet received 150g/kg per day.

Next steps. A series of experiments are planned to dig deeper into the cranberry-vessel function link in several cases applying tests used on humans to the pigs. For instance people with atherosclerosis take flow-mediated vasodilation tests using ultrasound to measure the change in size of the blood vessels and in flow rate. “We also will be measure CRP (C-reactive protein), which some people think is a predictor of cardiovascular disease,” Kruse-Elliott said. “Furthermore, we want to correlate all those findings with LDL (levels), which should yield important physiological results as well as further validating the FH model,” she said.

And what will be the diet of choice in the next stage? It turns out pigs like whole cranberries. Tart and yummy.

Sex hormones linked to artery weaknesses

MedlinePlus: Sex hormones linked to artery weaknesses

SAN DIEGO, Apr 05, 2005 (United Press International via COMTEX) — U.S. researchers have found that hormones may be the reason men are four times more likely to develop aneurysms.

Researchers at the University of Kentucky found when they removed circulating hormones, including testosterone and dihydrotestosterone, from male mice, they lowered their risk of developing aneurysms — dangerous weaknesses in arterial walls. When the researchers gave female mice the same male sex hormones, their aneurysm risk increased to the level of males.

The female mice given the male sex hormones also developed more severe aneurysms compared to female mice given placebos.

The goal now is to find out why the hormones affect the walls of the arteries in this way. If scientists can determine a link, they might be able to develop a drug treatment to prevent aneurysms.

Swedish “health drink” could cause Alzheimers

Never heard this before, always thought spirulina was supposed to be good for you.

The Local - Swedish “health drink” could cause Alzheimers

A Swedish juice manufacturer has withdrawn one of its products after scientists in Stockholm discovered that its key ingredient could cause Alzheimers and Parkinsons. The drink, made by Brämhults, contains spirulina algae, which scientists have now discovered produces the poisonous substance BMAA.

The scientists who made the discovery are as yet unsure whether the health drink actually contains BMAA, or whether the substance disappears during the production process. Birgitta Bergman of Stockholm University, who discovered the link between the algae and BMAA, told Aftonbladet that she would conduct tests on the drink in the coming months.

On hearing of the discovery, Brämhults made an immediate decision to withdraw the drink from the market. The spirulinna drink has been on sale for six years.

Managing director Thomas Gustafsson said that the company would not sell the product if there was the slightest doubt about its safety. Other juice drinks in the company’s range, which do not contain spirulin, will not be taken off the shelves.

The research which led to the discovery of the effects of BMAA started after islanders on the Pacific island of Guam were hit by neurological illnesses. It was discovered that the substance could be found in a type of nut popular among islanders.

It was later discovered that Alzheimer patients in a study had BMAA in their brains, while healthy people did not. The latest research has linked the substance to the type of blue-green algae that blossoms every summer in the Baltic Sea, Svenska Dagbladet reported.

Electroacupuncture can lower blood pressure

temporarily, in rats

Electroacupuncture can lower blood pressure

Dr. John C. Longhurst, director of the Susan Samueli Centre for Integrative Medicine at UC Irvine ,and researchers, have found that acupuncture using low levels of electrical stimulation can lower elevations in blood pressure by as much as 50 percent.

Acupuncture, an ancient form of Chinese medicine, involves inserting needles at specific points on the body to help cure disease or relieve pain.

The study, which appears in the March issue of the Journal of Applied Physiology, found that electroacupuncture treatments on rats provided temporary relief from the conditions that raise blood pressure during hypertensive states and they believe the treatment has the potential to become part of a therapeutic regimen for long-term care of hypertension and other cardiovascular ailments in people.

Longhurst says the study suggests that acupuncture can be an excellent complement to other medical treatments, especially for those treating the cardiac system and the Western World is waiting for a clear scientific basis for using acupuncture. He hopes the research will lead to the integration of ancient healing practices into modern medical treatment.

Longhurst and his UCI colleagues had already identified in previous studies, at the cellular and molecular level, how acupuncture excites brain cells to release neurotransmitters that either inhibit or heighten cardiovascular activity.

In this later study they found that when an acupuncture needle was inserted at specific sites on the wrist, inside of the forearm or leg, it triggered the release of opioid chemicals in the brain that reduce excitatory responses in the cardiovascular system. This decreases the heart’s activity and its need for oxygen, which in turn can lower blood pressure, and promotes healing for a number of cardiac ailments, such as myocardial ischemia ( insufficient blood flow to the heart ) and hypertension.

The team first applied acupuncture to specific points on the forelimb of test rats with artificially elevated blood pressure rates; these same sites on humans are on the inside of the forearm slightly above the wrist. The acupuncture alone had no effect on blood pressure.

But when they added electrical stimulation to the acupuncture treatment by running an electrical current through the needles, low frequencies lowered increased blood pressure by as much as 40 to 50 percent. Overall, the researchers found that a 30-minute treatment reduced blood pressure rates in the test rats by 25 mmHg - with the effect lasting almost two hours.

Longhurst, a cardiologist who is also the Lawrence K. Dodge Professor in Integrative Biology says this treatment is only effective on elevated blood pressure levels, such as those present in hypertension, and the treatment has no impact on standing blood pressure rates. Their goal is to help establish a standard of acupuncture treatment that can benefit everyone who has hypertension and other cardiac ailments.

Longhurst and his colleagues are currently testing this electroacupuncture treatment method in an ongoing human study.

Drs. Wei Zhou, Liang-Wu Fu, Stephanie C. Tjen-A-Looi and Peng Li of the UCI Department of Medicine participated in the study, which was funded by the National Heart, Lung and Blood Institute, and the Larry K. Dodge Endowed Chair.

Cognitive Therapy Successful Against Depression

Category: Depression

Yahoo! News - Cognitive Therapy Successful Against Depression

TUESDAY, April 4 (HealthDay News) — When provided by experienced psychotherapists, cognitive therapy may be as effective as antidepressant drugs in initial treatment of moderate to severe depression, a new study suggests.

The study, published in the April issue of the journal Archives of General Psychiatry, included 240 people with moderate to severe depression. One group of 60 people received cognitive therapy, another group of 120 received antidepressant medication (usually Paxil), and a third group of 60 received a placebo pill.

According to University of Pennsylvania researchers, patients in the cognitive therapy group attended two 50-minute sessions a week for the first four weeks of the study. They went to one or two sessions a week for the middle eight weeks and to one session a week for the final four weeks of the study.

After eight weeks of treatment, response rates were 50 percent in the medication group, 43 percent in the cognitive therapy group and 25 percent in the placebo group. After 16 weeks of treatment, response rates were 58 percent for patients receiving either medication or cognitive therapy. Remission rates were 46 percent for patients receiving medication and 40 percent for those in the cognitive therapy groups.

“On the whole, these findings do not support the current American Psychiatric Association guideline, based on the TDCRP (the Treatment of Depression Collaborative Research Program) that ‘most (moderately and severely depressed) patients will require medication,’ ” the study authors wrote.

“It appears that cognitive therapy can be as effective as medications, even among more severely depressed outpatients, at least when provided by experienced cognitive therapists,” they wrote.

Study Reveals Differing Amounts of Naturally Occurring Flavanols in Chocolate and Cocoa Powder

- Natural Cocoa Powders, Unsweetened Baking Chocolates Rank Highest in Findings

SAN DIEGO, April 4 /PRNewswire/ — A new Agricultural Research Service (ARS) study evaluating total amounts of flavanols and antioxidant capacity in cocoa and chocolate shows that antioxidants are found in a range of chocolate products — but more so in those with a higher cocoa content.

Scientists from ARS, the chief scientific research agency of the U.S. Department of Agriculture, presented the findings today at Experimental Biology 2005, an international scientific conference held in San Diego. The study was funded in part by the American Cocoa Research Institute (ACRI), the research arm of the Chocolate Manufacturers Association (CMA).

In this study, the scientists found that the chocolates ranked in antioxidant capacity from highest amount to lowest were natural cocoa powder, unsweetened baking chocolate, alkalinized or “Dutch” cocoa powder, dark chocolates, semi sweet chocolate baking chips, and milk chocolates.

The results were based on chocolate samples from commercially available products under nine brands, as well as reference standards provided by the United States National Institute of Standards and Technology (NIST). ARS scientists, located at the Beltsville Human Nutrition Center, Brunswick Labs, and the Arkansas Children’s Nutrition Center analyzed these samples in a blind test for flavanol content and antioxidant capacity.

Flavanols are the main flavonoids found in cocoa and chocolate. Research over the past decade has identified flavonoids as showing diverse beneficial physiological and antioxidant effects. Flavonoids are compounds also found in fruits, vegetables, and certain beverages such as tea, red wine, and grape juice.

“These results indicate that products derived from cocoa beans, which come from the cacao tree, also contain flavanols, with the highest amount in natural cocoa powders,” explains Dr. Leah Porter, vice president of scientific affairs for the CMA. “This study also demonstrates that chocolate products containing higher amounts of cocoa have higher antioxidant capacity.”

“The findings provide further scientific evidence that cocoa is a rich source of antioxidant activity, such as other antioxidant-rich foods including red wine, cranberries and blueberries,” said CMA President Lynn Bragg. “This research increases knowledge of a wonderfully familiar food, and comes at a time when we are finding new ways to use cocoa and chocolate (e.g., as an ingredient and flavor) in a variety of foods. There is a chocolate for everyone and it can be enjoyed — in moderate portions — as part of a balanced diet.”

According to Chef Carole Bloom, a chocolate expert and award-winning author of Chocolate Lover’s Cookbook for Dummies, All About Chocolate, and Truffles, Candies, and Confections, there are many ways to incorporate cocoa and chocolate into a diet in a way that enhances the flavor of healthy foods. Some suggestions include:

— Sprinkle cocoa powder on popcorn, warm and cold coffee drinks, low fat
or non fat plain yogurt mixed with fresh fruit, and baked pears, apples
or other fruit

— Mix small bite-size pieces of dark chocolate in with a homemade trail
mix of nuts and dried fruits

— Add chocolate shavings or cocoa nibs to fresh fruit cups, salad greens,
or cold cereals such as granola or warm cereals such as oatmeal or
cream of wheat

— Dip fresh or dried fruits such as strawberries, bananas or dried
apricots into chocolate

— Add chocolate chips into easy to bake vegetable breads or cakes such as
banana bread, pumpkin bread, or carrot cake

— Incorporate into sauces such as Mexican mole and use with chicken,
fish, turkey or pork

Bragg summarized, “Chocolate has been and will continue to be an important research area, and we are constantly learning more about its many unique properties. The CMA is supportive of industry research that increases the understanding of the dietary contribution and role of flavanols in a healthy lifestyle.”

About the Chocolate Manufacturers Association

The Chocolate Manufacturers Association (CMA) has served as the premiere trade group for manufacturers and distributors of cocoa and chocolate products in the United States since 1923. The association was founded to fund and administer research, promote chocolate to the general public and serve as an advocate of the industry before Congress and government agencies. CMA’s mission is to serve as the voice of the American chocolate industry and through research, education and public information, works to ensure a continued supply of cocoa and consumption of high value and quality chocolate products for the American people. CMA members represent over 90% of the chocolate processed in the United States. For more information on CMA visit http://www.chocolateusa.org .

Concord Grape Juice Lowered Blood Pressure in Preliminary Clinical Study; Also Lowered BP, Cholesterol and Inhibited Atherosclerosis in Lab Study

Concord Grape Juice Lowered Blood Pressure in Preliminary Clinical Study; Also Lowered BP, Cholesterol and Inhibited Atherosclerosis in Lab Study

SAN DIEGO, Calif.–(BUSINESS WIRE)–April 4, 2005–

Concurrent Studies Point to Positive Effect on Blood Pressure, Other Cardiovascular Risk Factors

Three current studies point to a positive effect of Concord grape juice consumption on blood pressure, adding to the growing body of scientific evidence that drinking Concord grape juice assists with healthy cardiovascular function. In a preliminary study published in the current issue of Biofactors, drinking Concord grape juice lowered the blood pressure of mildly hypertensive men by almost seven points.

In addition, two laboratory studies presented today at the Experimental Biology meeting in San Diego complement the Biofactors study; one offers a possible mechanism of action for the blood pressure effect, the other shows similar effects in a laboratory model that closely mimics human cardiovascular behavior.

The Biofactors study tested 40 Korean men with mild hypertension (blood pressure averaging 146/94 mm Hg). In a double-blinded study, half drank Concord grape juice for eight weeks while the other half drank a calorie-matched placebo drink. At the end of the study, the grape juice group had a significant decline of 7.2 mm systolic and 6.2 diastolic compared to baseline. The placebo group saw a lesser decrease in both measurements.

“It is exciting to see complementary research presented at the same time on a topic as important as blood pressure,” explains John D. Folts, Ph.D., Professor of Medicine at the University of Wisconsin School of Medicine and an author of one of the laboratory studies. “Nonetheless, we need to be cautious when interpreting preliminary data such as from the Korean study. For example, the placebo group also saw a small drop in blood pressure, although not a significant one, and while the Concord grape juice group’s numbers were significant compared to baseline, they did not reach significance when compared group to group. A larger trial will be necessary to confirm the blood pressure lowering effect.

“On the other hand, our study also saw the lowering of blood pressure in a laboratory model, as well as the lowering of cholesterol and the inhibition of atherosclerosis–all significant versus a placebo group and all of which adds credence to the Korean study, suggesting that the Concord grape juice is functioning on a number of levels in the cardiovascular system.”

In the second laboratory study presented at Experimental Biology, researchers from the Louis Pasteur University in Strasbourg, France, led by Valerie Schini-Kerth, Ph.D., found that Concord grape juice produced arterial relaxation by increasing the activity of a nitric oxide synthase in cells lining the arterial wall.

“Dr. Schini-Kerth’s data certainly suggest a mechanism whereby Concord grape juice-based polyphenols may reduce blood pressure by encouraging the relaxation of the artery wall,” notes Dr. Folts. “Previous studies by my group have shown that Concord grape juice enables the brachial arteries to expand to accommodate increased blood flow. Likewise, other researchers have shown that nitric oxide production from platelets may well be the mechanism behind Concord grape juice’s ability to reduce the tendency for the blood to clot. So there are a lot of supporting data in this area.”

The U.S. National High Blood Pressure Education Program estimates that lowering systolic blood pressure by five points would results in a 14% drop in deaths from stroke, a 9% drop in heart disease deaths, and a 7% drop in overall mortality.

Experts also note that all foods should be consumed in moderation, and that a healthy diet should include a wide range of colorful fruits and vegetables, and complemented by regular physical exercise.

The Concord grape juice for these studies was provided by Welch Foods Inc. The laboratory studies were partially supported by grants from Welch Foods Inc.

Abstract:

Many of the flavonoids found in grapes and grape products such as juice or wine have been known to exert antioxidant, anti-inflammatory, platelet inhibitory and arterial relaxing effects either in vitro, in animal studies and in human trials. This study was designed to test the effect of Concord grape juice consumption on altering blood pressure in hypertensive patients. Forty subjects were given 5.5 ml/kg body weight/day of either Concord grape juice (CGJ) or a calorie-matched placebo drink every day for 8 weeks. Blood pressure (BP) was measured on weeks 0, 4 and 8. Compared to baseline, in the CGJ group systolic BP was reduced on average by 7.2 mm Hg (p = 0.005) and diastolic BP was reduced on average by 6.2 mm Hg (p = 0.001) at the end of 8 weeks. Comparable changes in the group getting the placebo product were -3.5 mm Hg (NS) and -3.2 mm Hg (p = 0.05) Consuming Concord grape juice, which is high in polyphenolic compounds, may favorably affect BP in hypertensive individuals.

Health Benefits Help Peanuts Shed Stigma

Yahoo! News - Health Benefits Help Peanuts Shed Stigma

By ELLIOTT MINOR, Associated Press Writer

ALBANY, Ga. - Peanuts, a dietary outcast during the fat-phobic 1990s, have made a comeback, with consumption soaring to its highest level in nearly two decades and more doctors recommending nuts as part of a heart-healthy diet.

When peanut butter and snack peanuts plummeted as Americans switched to lowfat diets, the peanut industry responded with studies showing the health benefits of peanuts. Total consumption of peanuts jumped last year to nearly 1.7 billion pounds, compared to 1.5 billion pounds the year before.

The amount of snack peanuts eaten climbed to 415 million pounds in the 2003-2004 crop year, the highest since the mid-1990s. And peanut butter consumption soared to 900 million pounds, from a low of about 700 million in the ’90s.

“Mothers gave us peanuts and peanut butter. Now, we’ve figured out that Mom was right. But it took a lot of researchers and universities to figure that out,” said Don Koehler, executive director of Georgia’s Peanut Commission.

The federal government’s latest dietary guidelines say peanuts, which contain unsaturated fats, can be eaten in moderation.

“Now we know that the type of fat found in peanuts is actually good for us,” said Lona Sandon with the American Dietetic Association. “It doesn’t clog our arteries like saturated fat. It helps keep the arteries clean.”

But that’s only if you don’t overdo it, and that’s the part that often trips up peanut lovers. There are 14 grams of fat in one serving of peanuts, which is only one ounce. A handful can have up to 200 calories.

“The problem is that the portions need to be low so you don’t overconsume the calories — that’s where the public has a disconnect,” said Madelyn Fernstrom, director of the Weight Management Center at the University of Pittsburgh Medical Center. “It’s a well-spent 200 calories if you can limit it to that. The problem is volume. It’s very hard to have a small serving of peanuts, meaning a small handful.”

When peanuts were out of favor in the last decade, American consumers seemed to overlook the respectable list of nutrients — vitamin E, niacin, thiamin, riboflavin, vitamin B6, and minerals such as copper, phosphorous, potassium, zinc and magnesium. They also are a good source of fiber and protein.

Peanuts also have a small amount of resveratrol, the antioxidant in red wine that has been linked to the “French Paradox” — a low incidence of heart disease among the French, despite their love of cheese and other high-fat foods.

Research at several universities suggests peanuts may help prevent heart disease, that they can lower bad cholesterol and that they can help with weight loss, possibly by making people feel satisfied so they eat less overall. One Harvard study showed an association between peanut butter consumption and a reduced risk of diabetes.

Even the U.S. Food and Drug Administration has authorized a qualified health claim for peanuts and some tree nuts. Producers can say they may reduce their risk of heart disease by eating 1 1/2 ounces daily.

Anna Resurreccion, a University of Georgia food scientist, has focused her research on the resveratrol found in peanuts. By subjecting the nuts to stress — slicing the kernels, or subjecting them to ultrasound — the resveratrol level greatly surpassed that found in red wine, she said.

This development opens the door for new products, such as enhanced peanut butter that could offer even more health benefits and serve as a way to get resveratrol into children’s diets, she said.

“Young children can’t very well drink wine,” Resurreccion said. “But most of them love peanut butter and peanut snack foods.”

Web site lets patients shop around for hospitals

Category: Health

Yahoo! News - Web site lets patients shop around for hospitals
By Tony Pugh Knight Ridder/Tribune

People now can compare the quality of care at more than 4,200 hospitals nationwide through a new government Web site.

HospitalCompare.hhs.gov provides side-by-side, hospital-versus-hospital comparisons on 17 measures: eight related to heart-attack care, four to care for heart failure and five related to pneumonia care.

For instance, the Web site, which launched Friday, shows the percentage of a hospital’s heart-attack patients who, among other treatments, receive aspirin or beta-blockers on arrival and discharge. It also gives the percentage of heart-attack patients who get a thrombolytic agent–a drug to treat blood clots–within 30 minutes of arrival.

For heart-failure patients, the site details, among other things, the percentage who receive an ACE inhibitor–a medicine frequently used to treat heart failure–and the percentage of those who get instructions to help manage their conditions when they’re discharged.

Hospital accrediting agencies use such indicators to determine whether a hospital is delivering good basic practice. They add up to an impression that’s easily compared with those of other hospitals.

Similar comparisons for patient satisfaction and rates of infection will be added later this year, Medicare administrator Mark McClellan said in a teleconference Friday. Hospital mortality rates are being considered for the site, he said.

The data, taken from patient records from the previous year, will be updated quarterly. People who don’t have computers can get the same information by calling 1-800-Medicare and asking for an agent at the end of the recorded options.

The Web site lets people compare hospitals in their areas. All but 60 U.S. hospitals are participating in the voluntary service, which was established by the Hospital Quality Alliance, a public-private partnership that includes hospitals, government agencies, consumer groups and health-care organizations such as the American Hospital Association.

Officials hope that listing the percentages of hospital patients who receive proven, effective medical treatments will help people make more informed choices about their hospital care. They stressed that the choice of hospitals should be made in collaboration with patients’ primary physicians.

The reporting system builds on provisions of the Medicare Modernization Act, which offers financial incentives for hospitals to report their quality measures publicly.

“We strongly believe that payment incentives work to get quality reporting and quality improvement, when we use measures that are clinically valid and feasible to produce,” McClellan said.

Half of All Cancer Deaths Preventable: Report

Yahoo! News - Half of All Cancer Deaths Preventable: Report

By Maggie Fox

WASHINGTON (Reuters) - More than 60 percent of all cancer deaths could be prevented if Americans stopped smoking, exercised more, ate healthier food and underwent recommended cancer screenings, the American Cancer Society reported on Thursday.

Americans could realistically cut the death rate in half, the report says. This year 1.368 million Americans will learn they have cancer and 563,700 will die of it.

“The American Cancer Society estimates that in 2005, more than 168,140 cancer deaths will be caused by tobacco use alone,” the organization said in a statement.

“In addition, scientists estimate that approximately one third (190,090) of the 570,280 cancer deaths expected to occur in 2005 will be related to poor nutrition, physical inactivity, overweight, obesity and other lifestyle factors.”

That totals 358,230, or 62 percent, of all cancer deaths.

“The issue is how many could you actually pull off in reality and half doesn’t seem like a big stretch,” Dr. Michael Thun, head of epidemiology for the non-profit group, said in an interview.

“If one could eliminate tobacco use, you would eliminate about half of cancer deaths. If you could help people maintain a healthy body weight and get more physical activity, that would be another 10 percent,” he added.

“Increasing colorectal screening and high quality mammography and Pap (tests for cervical cancer) would contribute another fraction. It is very plausible that one could get a 50-percent reduction.”

For instance, breast cancer, which kills 40,000 women and men in the United States every year, can usually be easily treated if caught before it spreads. In February a team at Harvard Medical School calculated that if every woman aged between 50 and 79 got a mammogram every year, it would reduce deaths from breast cancer by 37 percent.

Colon cancer and prostate cancer, two other top cancer killers, are also easily detected early with proper screening.

KILLER TOBACCO

But the single easiest way to prevent cancer would be to stop all tobacco use, the report says.

“What we have learned from tobacco is that in addition to education, measures that make a huge difference are things like increasing excise taxes on cigarettes and the clean air laws that have been enacted to protect nonsmokers from secondhand smoke,” Thun said.

Encouraging smokers to quit and changing social norms about smoking have also helped drive the nation’s smoking rate below 25 percent, he said.

Tackling obesity will be more difficult, Thun said.

“Just from a common-sense point of view, anything which increases physical activity, makes healthy food more available, limits access (to) and marketing of unhealthy foods is likely to be a step in the right direction,” Thun said.

He also said schools need to examine ways to get sugary sodas out of vending machines and find other sources of revenue that do not threaten the health of youngsters.

Thun said the report was not meant to make cancer patients feel they caused their own disease.

“This says just the opposite. The reality is things like smoking and obesity and physical inactivity are often described as voluntary but the choices we make are made in a social context,” he said.

“In designing our communities and our lives, we inadvertently have made a lot of choices that work against health.”

Fruit, Veggies Tied to Lower Pancreatic Cancer Risk

Yahoo! News - Fruit, Veggies Tied to Lower Pancreatic Cancer Risk

By Amy Norton

NEW YORK (Reuters Health) - New research from Canada suggests that a diet rich in fruits and vegetables may help prevent pancreatic cancer, a particularly deadly type of tumor.

The findings, based on a comparison of 585 pancreatic cancer patients and about 4,779 adults without the disease, suggest that the risk of the cancer declines as fruit and vegetable intake increases.

Among cancers, pancreatic tumors have one of the most dismal survival rates, with less than 5 percent of patients still alive 5 years after diagnosis. The poor prognosis is in large part due to the fact that the disease is rarely caught early.

Because of this, uncovering the modifiable risk factors for the disease is vital, according to Dr. Parviz Ghadirian of the University of Montreal, one of the authors of the new study.

Using data from a large study of Canadians diagnosed with cancer between 1994 and 1997, Ghadirian and his colleagues found that higher intakes of fresh fruit and cruciferous vegetables, such as broccoli and cauliflower, were associated with a lower risk of pancreatic cancer.

For reasons that are unclear, the relationship was confined to men; those with the highest fruit and vegetable intakes were about half as likely to develop pancreatic cancer as those with the lowest intakes. There was no clear association between diet and pancreatic cancer risk among women.

The findings, published in the International Journal of Cancer, add to a growing body of evidence on the role of diet in pancreatic cancer risk. Some research has tied higher consumption of fruits, vegetables and fiber to a lower risk of the disease, while other studies have suggested that diets heavy in saturated fat, salted meats or dairy products may raise the risk.

In the current study all of the subjects filled out questionnaires on their lifestyle habits, which included reporting how often they’d eaten various foods over the previous two years.

In a separate newly published study of the same group, Ghadirian and his colleagues found that the antioxidant lycopene, specifically, appeared protective against pancreatic cancer — again, only men.

Lycopene, obtained mainly through tomatoes and tomato products, belongs to a family of plant compounds called carotenoids, some of which are converted in the body to the antioxidant vitamin A.

In the current study, adults with high intakes of fruits and vegetables tended to favor fresh fruits like apples, oranges and cantaloupe, and cruciferous vegetables like broccoli and cauliflower. These foods, Ghadirian and his colleagues note, are key sources of carotenoids and vitamin C. another antioxidant that has been tied to lower pancreatic cancer risk.

It’s thought that antioxidants may help ward off cancer by mopping up oxygen free radicals — molecules that, though a natural byproduct of metabolism, can result in potentially disease-causing damage to cells over time.

With its often rapidly fatal course, the only way to address pancreatic cancer right now is through prevention, Ghadirian and his colleagues note in their report.

Not smoking is one way to do that, Ghadirian said, and following a diet rich in fiber, fruits and vegetables may be another.

Cranberries May Help Keep Arteries Clear

Yahoo! News - Cranberries May Help Keep Arteries Clear

SUNDAY, April 3 (HealthDay News) — In a study in pigs, cranberry juice helped relax blood vessels clogged with high blood cholesterol and narrowed by atherosclerosis, according to a study by researchers at the University of Wisconsin School of Veterinary Medicine.

The pigs used in the study had a genetic defect — familial hypercholesterolemia (FH) — that causes them to develop high blood cholesterol, which in turn causes atherosclerosis and vascular dysfunction. However, some of these pigs were fed cranberry juice powder, made from whole cranberries, for six months and their blood vessels started to function like those in normal pigs.

FH pigs that weren’t fed the cranberry powder had much less vascular relaxation than either normal pigs or the FH pigs that ate the cranberry powder.

The study was to be presented Sunday at the Congress of the International Union of Physiological Sciences, in San Diego.

“Since the abnormal functioning of blood vessels is an important component of heart disease, finding ways to improve vascular function in patients with high cholesterol and atherosclerosis is critical to helping protect these patients from consequence such as heart attack or stroke,” study lead researcher Kris Kruse-Elliott said in a prepared statement.

“The value of fruits and vegetables in our diet has recently been an area of intense research, and studies like this help us to understand the specific mechanisms by which the nutrients we consume can protect against heart disease,” she said.

The research team now plans to determine which components of cranberries are most important in improving vascular relaxation.

The Glycemic Index

What is the Glycemic Index?

The glycemic index is a ranking of carbohydrates based on their immediate effect on blood glucose (blood sugar) levels. It compares foods gram for gram of carbohydrate. Carbohydrates that breakdown quickly during digestion have the highest glycemic indexes. The blood glucose response is fast and high. Carbohydrates that break down slowly, releasing glucose gradually into the blood stream, have low glycemic indexes.

What is the Significance of Glycemic Index?

• Low GI means a smaller rise in blood glucose levels after meals

• Low GI diets can help people lose weight

• Low GI diets can improve the body’s sensitivity to insulin

• High GI foods help re-fuel carbohydrate stores after exercise

• Low GI can improve diabetes control

• Low GI foods keep you fuller for longer

• Low GI can prolong physical endurance

What is Glycemic Load?

• Glycemic load builds on the GI to provide a measure of total glycemic response to a food or meal

• Glycemic load = GI (%) x grams of carbohydrate per serving

• One unit of GL ~ glycemic effect of 1 gram glucose

• You can sum the GL of all the foods in a meal, for the whole day or even longer

• A typical diet has ~ 100 GL units per day (range 60 - 180)

• The GI database gives both GI & GL values

How to Switch to a Low GI Diet

• Use breakfast cereals based on oats, barley and bran

• Use “grainy” breads made with whole seeds

• Reduce the amount of potatoes you eat

• Enjoy all types of fruit and vegetables (except potatoes)

• Eat plenty of salad vegetables with vinaigrette dressing

Girls Follow Mom’s Lead When Eating Fruits, Veggies

Yahoo! News - Girls Follow Mom’s Lead When Eating Fruits, Veggies

By Alison McCook

NEW YORK (Reuters Health) - When mothers add more fruits and vegetables to their plates, their daughters do as well, new research reports.

Furthermore, moms who ate diets heavy in fruits and veggies were less likely to pressure their daughters to eat more, and their daughters were less likely to become so-called “picky” eaters.

Many parents worry about picky eating in their children. In this study, girls who were picky eaters typically ate less fruits and vegetables than healthy eaters.

However, all girls — whether they picked at their food or not — lacked important nutrients such as calcium and magnesium, study author Dr. Amy T. Galloway told Reuters Health.

Furthermore, picky eaters also ate less fat and sugar, and were less likely to be overweight than girls who were not picky eaters.

“Picky eating has both costs and potential benefits,” said Galloway, who is based at Appalachian State University in Boone, North Carolina. “Our findings show that all girls would benefit from consuming more fruits and vegetables, so it may not be worth it for parents to single out picky eaters.”

During the study, Galloway and her colleagues interviewed 173 mothers and their 7-year-old white, non-Hispanic daughters about eating habits, and whether mothers pressured their girls to eat more. When girls turned 9, the researchers contacted them again and determined if they were picky eaters, meaning they only ate a few foods, often refused to eat family meals, and were picky or fussy about what they ate.

Overall, mothers who ate more fruits and vegetables had daughters who ate more fruits and vegetables, Galloway and her team report in the Journal of the American Dietetic Association.

Girls whose mothers put pressure on them to eat at age 7 were more likely to be picky eaters at age 9. Picky eaters ate less fruits and vegetables, and were at greater risk of not getting enough vitamins E and C than were non-picky eaters. Picky eaters also ate less fiber.

However, picky eaters were less likely to be overweight and were not underweight. All girls in the study lacked vitamin E, calcium and magnesium, Galloway said.

“Most of the girls in our study, regardless of whether they were picky eaters, did not consume recommended quantities of fruits and vegetables,” she said. “Our findings indicate that (picky eating) might not be as big of a problem as we have assumed.”

Galloway added that the same trends may not be present in young boys, because parents often have different weight expectations for their sons, which may affect parental pressure to eat and boys’ eating habits.

Arthritis Inflammation Increases Cardiac Death Risk

Yahoo! News - Arthritis Inflammation Increases Cardiac Death Risk

NEW YORK (Reuters Health) - Systemic inflammation increases the risk of dying from cardiovascular disease in patients with rheumatoid arthritis, a new study shows, even after factoring in the effects of traditional cardiovascular risk factors and other illnesses.”

The rate of illness and death from cardiovascular disease is higher among rheumatoid arthritis patients, and there is increasing evidence that inflammation plays a key role in the development of atherosclerosis, also known as hardening of the arteries, Dr. Sherine E. Gabriel of the Mayo Clinic in Rochester, Minnesota, and colleagues report in the medical journal Arthritis and Rheumatism.

They therefore conducted a study to investigate if evidence of more severe inflammation in rheumatoid arthritis patients might be associated with an increased risk of death from cardiovascular disease.

Gabriel and colleagues looked at 603 patients with rheumatoid arthritis, representing all residents of Rochester 18 years or older who were diagnosed with rheumatoid arthritis between 1955 and 1995. Study subjects were followed for an average of 15 years.

The researchers found a number of factors and other illnesses increased the risk of cardiovascular death, including personal history of cardiovascular disease, high blood pressure, diabetes mellitus, cancer and history of alcoholism.

After accounting for these factors, the researchers found that three markers of inflammation were independently associated with a greater risk of cardiovascular death.

These included having at least three high erythrocyte sedimentation rate tests; rheumatoid arthritis vasculitis; and rheumatoid lung disease. Swelling of large joints also was associated with a greater risk of cardiovascular death.

In addition, the researchers found that corticosteroid drug use increased the risk of cardiovascular death among rheumatoid arthritis patients who had no history of heart disease, but reduced cardiovascular death risk among those who did have a history of heart disease.

While these drugs can promote high blood pressure and high cholesterol, the researchers note, their anti-inflammatory effects may benefit patients with existing heart disease.

The researchers suggest that new studies should investigate whether aggressive treatment to tightly control systemic inflammation in rheumatoid arthritis patients can reduce the risk of cardiovascular death — similar to the benefits of tightly controlling blood sugar levels in diabetics.

Belly Fat Good Predictor of Diabetes in Men

Yahoo! News - Belly Fat Good Predictor of Diabetes in Men

NEW YORK (Reuters Health) - Overall obesity, measured by high body mass index (BMI) — the height-to-weight ratio, and abdominal obesity, measured by a large waist circumference, each strongly and independently predict the risk of type 2 diabetes in men, but abdominal obesity appears to be the better predictor, new research shows.

“Both BMI and waist circumference are useful for assessing health risk and should be measured in clinical settings…whenever possible,” the investigators say. But abdominal fat measured by waist circumference “can indicate a strong risk for diabetes whether or not a man is considered overweight or obese according to his BMI,” lead author Dr. Youfa Wang added in a statement.

In the study, investigators compared the predictive power of BMI, waist circumference, and waist-to-hip ratio for the development of type 2 diabetes in 27,270 men participating in the Health Professionals Follow-up Study.

During 13 years of follow-up, a total of 884 men developed type 2 diabetes, Wang, from Johns Hopkins Bloomberg School of Public Health in Baltimore, and colleagues report in the American Journal of Clinical Nutrition.

According to the team, as waist circumference increased, so did the risk of developing diabetes, with the risk in men with the highest waist circumference increasing by 12-fold, they report.

A similar graduated risk was seen for waist-to-hip ratio and BMI, with the largest values associated with a 7-fold and 8-fold increased risk, respectively.

“Our findings support the contention that the measurement of waist circumference should be used in clinical practice instead of waist-to-hip ratio,” the investigators write.

The study findings also suggest that the currently recommended cutoff for high waist circumference of 102 cm (40 inches) for men may need to be lowered to 95 cm.

“Many of the men who developed type 2 diabetes had measurements lower than the cutoff, Wang said, “and the risk associated with the waist circumference increased at a much lower level.”

Insurers start paying doctors for online “visits”

Category: Health

Clark Howard Show Notes Wednesday, March 23

Have you ever come down with a little sickness and you’re not sure whether to take a day off work or charge through it? Right now, it’s an either-or situation. You either have to go see a doctor and take a time off or you suck it up for a day or two. The trouble is that all you really need is advice. The idea of e-mailing with your doctor was proposed several years ago, but some doctors were not happy with this because they weren’t getting any compensation from the insurance companies. But now, several medical insurers are experimenting with paying doctors for online consultations. Patients pay a much smaller visit fee such as $5 and the doctor receives a much smaller consultation fee. But it frees up your time and the doctor’s time and is much more efficient. The first company to adopt this model is Kaiser Permanente and it’s been hugely successful for them. So, more and more insurers are getting involved with online treatment. Check with your health care provider next time you have a health issue.

Low-Cost Measures Could Prevent 72 Percent Of Newborn Deaths Worldwide

For some reason the article didn’t just list the “16 simple, cost-effective interventions” that could save so many babies, maybe they want you to buy the Lancet. Anyway, they do hint at a few, so maybe we can still save a baby or two.

Low-Cost Measures Could Prevent 72 Percent Of Newborn Deaths Worldwide

Nearly 72 percent of the 4 million newborn babies that die each year worldwide could be saved by implementing 16 simple, cost-effective interventions, according to a study published in the March 11, 2005, print edition of The Lancet. The study is the second in a four-part series of articles on newborn survival produced by a team of international health and development agencies and made available online March 3. Some of the cost-effective measures identified by the researchers include providing tetanus vaccinations for pregnant women, delivering babies in a clean environment, exclusively breastfeeding infants, providing extra care for low-birth-weight babies and antibiotics for neonatal infection.

“Nearly 40 percent of all child deaths worldwide occur in the neonatal period, or the first month of life, and three quarters of those deaths occur within the first week of life,” said Gary Darmstadt, MD, lead author of the study and associate professor in the Department of International Health at the Johns Hopkins Bloomberg School of Public Health and senior research advisor for the Saving Newborn Lives Initiative of Save the Children/USA. “Early success in preventing neonatal deaths is possible, even in settings with high mortality and weak health systems. Outreach services and family-community care, aimed to improve home care practices, raise demand for skilled care and increase care-seeking for illness can have a dramatic impact.” According to Dr. Darmstadt and his co-authors, outreach services and family care alone could prevent 35 percent of neonatal deaths.

While effective interventions are available, coverage is particularly lacking during the early days of life in many countries. The study estimates that effective interventions provided during the period immediately following birth may avert as many deaths as proven interventions implemented during childbirth, but at half the cost.

“Community-based initiatives that engage and empower communities, and promote the adoption of evidence-based maternal and newborn care practices could go a long way towards reducing neonatal mortality worldwide. In order to achieve the kinds of reductions that are needed to meet the United Nations Millennium Development Goal for child survival by 2015, however, we must simultaneously strengthen and expand clinical care for both mothers and babies,” said Dr. Darmstadt.

“Evidence-based, cost-effective interventions: how many newborn babies can we save?” was written by Gary L. Darmstadt, Zulfiquar A. Bhutta, Simon Cousens, Taghreed Adam, Neff Walker and Luc de Bernis for the Lancet Neonatal Survival Steering Team.

Funding was provided by Save the Children/USA, the Bill and Melinda Gates Foundation through grants from the World Health Organization, and by the Office of Health, Infectious Diseases and Nutrition, Global Health Bureau of the United States Agency for International Development through grants to the Johns Hopkins Bloomberg School of Public Health.

Red Wine Protects the Heart - polyphenols

At first the article says glasses, but later ounces. Unless they’re using really tiny glasses, I assume it’s one or the other, but not sure which. I vote for glasses.

Red Wine Protects the Heart

New Haven, Conn. — A review article of the latest studies looking at red wine and cardiovascular health shows drinking two to three glasses of red wine daily is good for the heart, according to a Yale School of Medicine researcher in the Journal of American College of Surgeons.

“The current consensus is that it is not just the alcohol, but something else,” said Bauer Sumpio, M.D., professor and section chief of vascular surgery in the Department of Surgery. “There are probably several mechanisms of protection from a cardiovascular viewpoint.”

He said researchers have been trying to pinpoint why red wine has a cardiovascular protective effect ever since the discovery of the so–called “French Paradox” in 1992 when researchers found a 40 percent lower mortality rate from ischemic heart disease among people in France despite the high amount of saturated fats in their diet.

Sumpio said there are several studies showing drinking two to three ounces of alcohol each day has a beneficial effect, but any more than that and the alcohol begins to have a negative health effect. Studies comparing spirits, beer and wine show some benefit from spirits and beer, but an overwhelming benefit from drinking red wine.

His laboratory found polyphenols, minus the alcohol, are powerful anti–oxidants. Polyphenols also are found in fruit, particularly berries, as well as green tea and chocolate. Anti–oxidants slow cell deterioration. The polyphenols also help prevent the build up of plaque on the smooth muscle cells, as well as inhibit platelet formation, which can lead to blood clotting.

“A better understanding of the health benefits of red wine and perhaps the specific polyphenolic extracts with the described properties would be a great contribution to society,” Sumpio said.
