Syringe type affects HIV transmission among intravenous drug users, according to a study by researchers at RTI International.
A JAMA study finds programmatic failures and common problems that occur along the path to mother-to-child transmission prevention, including HIV testing inadequacies and patients not taking their medications, authors say. Nevirapine's usefulness is limited by how many infected and at-risk persons receive the drug, says Elizabeth Stringer, M.D., UAB associate professor of obstetrics and gynecology and the lead author of the study in the JAMA HIV/AIDS theme issue.

A risk reduction program focused on African American heterosexual couples appears to diminish risky sexual behaviors among couples in which one partner is HIV-positive and the other is not, according to a report posted online today that will appear in the September 27 print issue of Archives of Internal Medicine, one of the JAMA/Archives journals. The study was published online today in advance of its upcoming presentation at the International AIDS Conference in Vienna, Austria.
The analysis of insurance records of more than 1.4 million U.S. men over 40 found that those who used ED drugs were more likely to have sexually transmitted diseases than were non-users. Physicians who prescribe erectile dysfunction drugs for their male patients should be sure to discuss the importance of safer sex practices, even with older patients.

Community-based HIV testing programs generally use only HIV antibody testing, but nucleic acid testing (NAT) can detect the presence of HIV earlier. Researchers at the UCSD School of Medicine studied more than 3,000 patients who sought HIV testing in community-based clinics in or near San Diego to examine the yield of testing with a rapid test plus NAT and to see whether patients would be willing to access their results by phone or computer.

In his Global Health Grand Rounds lecture, President Kikwete discussed the most significant challenges facing Tanzania, with a particular focus on health care and the advances made during his first term.
Despite national guidelines aimed at improving sexual health services for teenagers, most sexually active boys — even those who report high-risk sexual behaviors — still get too little counseling about HIV and other sexually transmitted infections (STIs) during their visits to the doctor, according to a study led by researchers at Johns Hopkins Children’s Center.
An approach designed to reduce HIV/STDs previously used exclusively by academic researchers has successfully been implemented by community-based organizations (CBOs), an important component in national strategies to curtail the spread of HIV, meaning far more “at risk” youths can be reached.

Important new research by University of Michigan Health System scientists has discovered that bone marrow, previously thought to be resistant to the HIV virus, can contain latent forms of the infection. The finding helps explain why it’s hard to cure the disease.
Researchers successfully removed CCR5 — a cell receptor to which HIV-1 binds for infection but which the human body does not need — from human cells. Individuals who naturally lack the CCR5 receptor have been found to be essentially resistant to HIV.
A new study finds that while nevirapine works well to prevent mother-to-child HIV transmission, a single dose of nevirapine in infected pregnant women can trigger resistance to some forms of the AIDS-drug cocktail known as combination antiretroviral treatment (ART). This nevirapine-induced resistance fades after about 12 months and no longer hinders ART, say UAB researchers working in Zambia.
