Antiviral drugs help prevent HIV infection in IV drug users

Treating intravenous drug users with antiviral drugs may reduce their chances of HIV infection, according to a new study published Wednesday in the British medical journal The Lancet.

The Bangkok Tenofovir Study was done in Bangkok, Thailand, from 2005-2013. It was run by the Centers for Disease Control and Prevention in collaboration with the Thailand Ministry of Public Health.

Researchers recruited more than 24,000 people at 17 sites. Half took the pill tenofovir - an antiretroviral drug - daily, while the other half got a placebo. Participants were followed for about four years. Researchers found those taking the drug cut their chances of infection by 49% almost in half - approximately 49%.

BPA linked to obesity in young girls

Poor diet and lack of exercise might not be the only factors contributing to the obesity epidemic. A new study suggests the environment may also play a role.

“Eating too much and exercising too little are important factors,” said Dr. De-Kun Li, a reproductive and perinatal epidemiologist at Kaiser Permanente in Oakland, California. “But they cannot explain the steep increase in the obesity rate the last three decades. We haven’t really changed our eating habits and exercise that much.”

The environmental culprit, according to the study published Wednesday in the journal PLOS ONE, may be bisphenol-a, a chemical commonly found in plastic and cans.

Li and colleagues studied 1,326 school-age children in Shanghai, China, and measured BPA levels in their urine. In girls ages 9 to 12, higher BPA urine levels were associated with a doubled risk of obesity. And as BPA urine levels increased, so did the girls’ obesity risk - measured using their weight in reference to weight distribution in the population. FULL POST
