Antioxidants
Don't Cut Heart Disease Risk: Study NEW YORK (Reuters Health) - Antioxidants such as beta carotene and vitamin E don't cut the risk of dying from heart disease, and beta carotene may even slightly increase the risk, according to a new analysis of studies conducted in the past. As a result, researchers at the Cleveland Clinic Foundation said the use of supplements containing beta carotene and vitamin A (a beta carotene metabolite) should be actively discouraged and that clinical studies using the antioxidant be discontinued. FDA mulls growth hormone for healthy kidsTues June 10, 2003 It's a highly charged issue: Is it appropriate to give years of drug injections to children not diagnosed with an actual height-harming disease? Or would it open the floodgates to normal kids just yearning for an extra few inches?
The device, which looks a little like the metal detectors used in airports, works because different types of body tissue resonated in different ways when exposed to a fluctuating frequency of microwaves given off by the device. This resonance can be detected because it interferes with the signal. Promise in Strangling Tumors Theory: A drug that helps block blood supply to cancerous cells shows success in new trial. By Julie Bell The Baltimore Sun Originally published June 9, 2003
Dr. Judah Folkman felt a building excitement
as he sat in the third row of a cavernous Chicago exhibit hall, where
more than 5,000 scientists waited to learn if his decades-old theory was
right: Can you really fight cancer by blocking tumors' blood supply?
Several anti-tumor drugs based on that premise seemingly hadn't worked. Avastin, the Genentech drug Folkman was waiting to hear about, had once been among them - failing to help terminal breast cancer patients. But as the Harvard University researcher listened to the latest results last week, it seemed clear that Avastin was responsible for modest but striking results: It had extended the lives of colon cancer patients on chemotherapy by about five months.
Statin Drugs Touted for Many Diabetics
By EMMA ROSS, AP Medical Writer LONDON - Most adult diabetics (news - web sites) should be taking cholesterol-lowering drugs even if they have healthy cholesterol levels and no evidence of heart disease, a major new study has concluded. The results, which found that statin drugs cut the risk of heart attacks, strokes and the need for angioplasty or bypass surgery in diabetics by one-third, emerge from the largest study ever to test the power of statins.
Obesity Epidemic Sweeping U.S., Harvard
Forum Told
By Greg Frost BOSTON (Reuters) - Most Americans are too fat, are getting fatter faster, and aren't likely to get lean unless drastic changes are made in diet and lifestyle, participants at a Harvard University forum on obesity say. A day after U.S. Surgeon General Richard Carmona called America's obesity epidemic "the terror within," the forum heard staggering data on the size and cost of America's weight problem. "No part of the country has escaped it," Walter Willett, chair of the Harvard School of Public Health's nutrition department, said Wednesday as he showed how obesity had spread across the United States over the last two decades. Eating Fish may Fight Depression in Pregnant Women San Francisco, CA (Associated Press) Eating salmon, sardines or other fish might help pregnant women avoid depression before and after childbirth, a study suggests. Seafood -- especially tuna, herring, salmon and sardines -- contains omega-3 fatty acids, which prior studies have found counter depression and protect against heart disease. The federal government has warned pregnant
women about eating fish because of mercury contamination, but its
recommendations still allow eating up to 12 ounces a week of a variety of
species.
Vindication for the Atkins Diet? Research: Low-Carb Diet Trumps Low-Fat Plan But Not for Long
(Associated Press) A
month after Dr. Robert C. Atkins death, his much-ridiculed diet has
received its most powerful scientific support yet: Two studies in one of
medicine's most distinguished journals show it really does help people
lose weigh faster without raising their cholesterol. U.S. Urged to Put Warning Labels on Teflon Pans(Reuters) An Environmental group Thursday asked the Consumer Product Safety Commission to require that cookware coated with teflon and similar chemicals carry a label describing the health risks of the non-stick coating. The Environmental Working Group said in a study released on Thursday that cookware coated with Teflon-like coatings could reach 700 degrees Fahrenheit in 3 to 5 minutes, releasing 15 toxic gases and chemicals, including two carcinogens.
Women Benefit More Than Men from Quitting
Smoking
By Linda Carroll NEW YORK (Reuters Health) - While men and women both benefit from quitting smoking, women see bigger improvements in lung function, a new study shows. Researchers found that women's breathing improved more than twice as much as men's after kicking the habit, according to the study published in the American Journal of Epidemiology. Women may benefit from quitting more than men because they seem to be more susceptible to damage from cigarette smoking in the first place, according to Gail Weinmann, director of the Airway Biology and Disease Program in the Division of Lung Diseases at the National Heart, Lung, and Blood Institute, which sponsored the study.
Surprising Results for Colon Cancer DrugSan Francisco, CA (Associated Press) An experimental drug that has been essentially written off as a failure dramatically extended the lives of some of the sickest colon cancer patients, it's manufacturer, Genentech, said Monday. The news surprised Wall Street, sent the biotechnology
company's stock soaring and boosted the spirits of researchers working
with similar drugs in a field plagued by recent setbacks.
