A positive result would not mean automatic exclusion from Canada, Caplan said Tuesday.

HRT Use Helps Prevent Fractures Due To Osteoporosis When Initiated Before Age 60
The recently published JAMA article "Hormone Replacement Therapy and Prevention of Nonvertebral Fractures: A Meta-analysis of Randomized Trials," by David J. Torgerson, PhD. and Sally E. M. Bell-Syer, MSc., reaffirms that hormone replacement therapy (HRT) helps prevent nonvertebral fractures when therapy is started early in menopause. The most common nonvertebral fractures are those of the hip and wrist. "We found that HRT prevents nonvertebral fractures, especially in younger postmenopausal women. For women to obtain the most protective benefit, therapy should be started soon after the menopause," said Torgerson, the study author. more

Two studies Point To Benefits Of Purple Grape Juice
Two separate studies recently published in leading cardiovascular research journals -- one looking at mechanism of action, the other looking at clinical outcomes -- point to the "heart healthy" benefits of drinking purple grape juice. In the June 12th issue of Circulation researchers showed that drinking grape juice not only has a direct effect on important biological functions like blood clotting but it also appears to increase the body's levels of valuable antioxidants while reducing free radical production. In the May, 2001 issue of Atherosclerosis, researchers compared the effects of drinking purple grape juice, red wine, and dealcoholized red wine in hamsters. They found that purple grape juice, when compared to red wine and dealcoholized red wine, was at least as effective at: lowering total cholesterol; decreasing LDL; reducing atherosclerosis (vs. wine only) and increasing LDL lag times. more

AUA: Urologists Not Using Simple Blood Test For Prostate Cancer; Relying Instead On Expensive, Unnecessary Biopsies
Many men aren't benefiting from a simple blood test for prostate cancer, because their urologists aren't using the test to eliminate unnecessary and expensive prostate biopsies. That's the conclusion based on results from a survey of American urologists attending the American Urological Association's annual conference, held last week in Anaheim, Calif. more
