Two Studies Find Daily Pill Can Prevent HIV Infection

Photo Courtesy - ABC News Radio(NEW YORK) -- AIDS drugs can help prevent heterosexuals from acquiring HIV, according to two studies released Wednesday.

Researchers at University of Washington International Clinical Research Center and dubbed Partners PrEP, have found a daily dose of antiretroviral drugs reduce the risk of HIV infection among heterosexuals by at least 62 percent.

The study, funded by the Bill & Melinda Gates Foundation examined 4,758 couples in Kenya and Uganda in which one partner had HIV while the other didn't.

Although the study wasn't due for release until 2012, the findings were found to be so strong, that the trial was stopped early.

Another study, conducted in Botswana by the Centers for Disease Control and Prevention found that participants taking a daily dose of Truvada instead of placebo were 63% less likely to become infected by HIV.

“These are exciting results for global HIV prevention. We now have findings from two studies showing that PrEP can work for heterosexuals, the population hardest hit by HIV worldwide,” said Kevin Fenton, M.D., director of CDC’s National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention. “Taken together, these studies provide strong evidence of the power of this prevention strategy.”

Group Doctor Visits Beneficial to Well Being?

Comstock Images/Thinkstock(BALTIMORE) -- Group patient visits – a medical appointment during which five to 10 patients with the same condition, usually a chronic one, meet with a physician for a longer period of time than an individual session would last – “may be a feasible means of providing care to individuals with PD [Parkinson's disease],” according to researchers, because of their cost-effectiveness.

Researchers at the Johns Hopkins University School of Medicine tested the group visits model to see whether it would improve patient satisfaction and quality of life. In a study of 30 Parkinson’s patients, the authors of this latest research – published in Neurology – found that the quality of life measurements were no different in the group receiving group care compared to the one receiving standard, individualized care.

The group visits model has been used in diabetes patients, as well as with those who have heart disease and other illnesses, and has previously demonstrated improvements in patients' satisfaction and quality of life.
