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

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 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
