In health care reform discussions, talk inevitably turns to making hospitals and physicians accountable for patient outcomes. But in a commentary being published in the July 14 issue of the Journal of the American Medical Association, Johns Hopkins patient safety expert Peter Pronovost, M.D., Ph.D., argues that the health care industry doesn’t yet have measurable, achievable and routine ways to prevent patient harm — and that, in many cases, there are too many barriers in the way to attain them.
GeoVax is developing a vaccine that presents the natural form of HIV envelope proteins to the immune system on virus-like particles with the envelope proteins present in clusters of three, a confirmation known as trimers.
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.

A team of researchers from the University of California San Diego and Mexico has found that even a modest behavioral intervention program averaging just 35 minutes can measurably reduce the incidence of HIV and sexually transmitted infections (STIs) among female sex workers in the U.S.-Mexico border region – and that the program succeeds at comparatively little expense.
Using an experimental mouse model for malaria, an international group of scientists has discovered that adding antioxidant therapy to traditional antimalarial treatment may prevent long-lasting cognitive impairment in cerebral malaria.
Scientists have shown that a specific virus can interact with a mutation in the host's genes to trigger disease. The observation may help explain why many people with disease risk genes do not actually develop disease.
Children exposed to polychlorinated biphenyls (PCBs) early in life later had a diminished immune response to diphtheria and tetanus vaccinations, according to a study published online June 20 ahead of print in the peer-reviewed journal Environmental Health Perspectives (EHP).
Routine use of HPV vaccine in males provides direct benefits to men and their sexual partners, will increase overall immunization rates among both males and females, and may be cost-effective; SAHM strongly recommends routine use of HPV vaccination in males as well as in females. We urge clinicians and insurance organizations to consider the benefit of routine vaccination for all age-appropriate patients, regardless of gender, in an effort to support the primary prevention of disease among adolescents and adults.
The largest study to date to examine methods to prevent HIV infection among breastfeeding infants concludes that giving antiretroviral drugs to HIV-infected breastfeeding mothers in sub-Saharan Africa or giving an HIV-fighting syrup to their babies are both effective.
Establishing a firm link between environmental change and human disease has always been an iffy proposition.

Currently, disinfecting formulations can take more than 10 minutes after application to eradicate a microorganism, and they are often toxic formulations. The amount of time required for effectiveness and the harm the products inflict on the environment make this an unrealistic and unviable solution to the problem. One scientist may have found an effective alternative.
According to Melanie Thompson, Principal Investigator at The AIDS Research Consortium of Atlanta (ARCA). "A vaccine that enhanced the body's ability to control HIV and delayed or decreased the dependence on anti-HIV drugs would be a major breakthrough for HIV treatment."

Every autumn, as predictably as falling leaves, flu season descends upon us. Every spring, just as predictably, the season comes to a close. This cyclical pattern, common in temperate regions, is well known, but the driving forces behind it have been in question.
The bacterium Helicobacter pylori, which lives in the human stomach and is associated with ulcers and gastric cancer, is shaped like a corkscrew, or helix. For years researchers have hypothesized that the bacterium’s twisty shape is what enables it to survive – and thrive – within the stomach’s acid-drenched environment, but until now they have had no proof.
