GAINESVILLE, Fla. — Rates of HIV have increased in Pakistan’s general population, as the virus has spread beyond at-risk groups to women and their children, according to an international team of researchers, including a University of Florida scientist.

The researchers raise concern that the transmission across subgroups into Pakistan’s general population may serve as indication that the virus may be spreading into populations within neighboring Afghanistan. The team’s epidemiological findings were published in July in the journal PLoS One. (more…)

COLLEGE PARK, Md. — Poultry farms that have adopted organic practices and ceased using antibiotics have significantly lower levels of drug-resistant enterococci bacteria that can potentially spread to humans, according to a groundbreaking new study led by a researcher in the University of Maryland’s School of Public Health.

The study, published in Environmental Health Perspectives (online August 10, 2011), is the first to demonstrate lower levels of drug-resistant bacteria on newly organic farms in the United States and suggests that removing antibiotic use from large-scale U.S. poultry farms can result in immediate and significant reductions in antibiotic resistance for some bacteria.

ANN ARBOR, Mich.— A study links low vitamin D in young girls with early menstruation, which is a risk factor for a host of health problems for teen girls as well as women later in life.

Researchers from the University of Michigan School of Public Health measured the blood vitamin D levels in 242 girls ages 5-12 from Bogota, Colombia, and followed them for 30 months. Girls low on vitamin D were twice as likely to start menstruation during the study than those with sufficient vitamin D, said epidemiologist Eduardo Villamor, associate professor in the U-M SPH.

About 50 to 60 percent of patients with melanoma have a mutation in the BRAF gene that drives the growth of their cancer. In clinical trials, most of these patients have responded remarkably well to two novel agents that inhibit the gene, but unfortunately, the response is almost always limited in duration, as the cancer develops a resistance to the drugs.

Even with Regular Exercise, People with Inactive Lifestyles More at Risk for Chronic Diseases, MU Researchers Say

COLUMBIA, Mo. – According to the Centers for Disease Control and Prevention, 25 percent of Americans have inactive lifestyles (they take fewer than 5,000 steps a day) and 75 percent do not meet the weekly exercise recommendations (150 minutes of moderate activity each week and muscle-strengthening activity twice a week) to maintain good health. After reviewing recent literature, University of Missouri researchers contend that physical inactivity is the primary cause of chronic diseases such as diabetes, obesity and fatty liver disease and that even people who set aside time for exercise regularly but are otherwise sedentary, may not be active enough to combat these diseases. Inactivity, in addition to the availability of high-caloric food has led to an increased rate of metabolic dysfunction in Americans. (more…)
