Insufficient evidence to support routine vitamin supplementation to prevent cancer and cardiovascular disease
The USPSTF found poor evidence to determine whether supplementation with these vitamins reduces the risk for cardiovascular disease or cancer. The available evidence from randomized trials is either inadequate or conflicting, and the influence of confounding variables on observed outcomes in observational studies cannot be determined. As a result, the USPSTF could not determine the balance of benefits and harms of routine use of supplements of vitamins A, C or E; multivitamins with folic acid; or antioxidant combinations for the prevention of cancer or cardiovascular disease. more

Depression doubles risk of death after bypass surgery
In the largest and longest study of its kind, researchers at Duke University Medical Center have definitively shown what previous studies have hinted at depression is a strong independent risk factor for death in patients who have undergone coronary artery bypass surgery to restore blood flow to the heart.  more


The doc tops the Internet as the preferred choice for women trying to find out about HRT

The case: Check the wristband
The patient was a 28-year-old female awaiting ambulatory surgery. She was very anxious about the impending surgery. The patient spoke English and appeared to be of average intelligence. The case was reported to AHRQ WebM&M by this circulating nurse, who noted, "I went to the surgical day care unit to meet my next patient. I picked up the chart that was next to this patient. The chart was correct for my next patient. I verbally stated the patient's name and this woman confirmed her name."  more

Topical microbicides: The future of preventing sexually transmitted diseases?
Even a partially effective microbicide, say experts, could avert more than 2 million HIV infections over a 3-year span. Besides protecting women from initial infection by disease-causing organisms, microbicides could play a critical role in reducing STD transmission from mother to infant during childbirth. Moreover, because female-to-male transmission of HIV is relatively inefficient, men would lessen their risk of infection if their HIV-positive female partners used a microbicide prior to intercourse.  more
