Physicians frequently prescribe antibiotics for common viral respiratory illnesses that typically do not benefit from antibiotic therapy, according to an article in tomorrow's issue of The Journal of the American Medical Association. The study, co-authored by Ralph Gonzales, MD, MSPH, assistant professor of medicine, University of Colorado Health Sciences Center, could offer insight into the rapidly rising prevalence of antibiotic-resistant bacteria.
Albany Medical College researchers have for the first time provided data that shows that the major predictor of resistance to AIDS drugs is whether the amount of virus in a patient's body has been reduced to nondetectable limits. The analysis showed that among the patients who received just Indinavir, those who were able to reduce the amount of virus in them to less than detectable levels had "significantly lower risks of emergence of resistance" to the drug. When combination therapy was used, such as a combined treatment of Indinavir, AZT, and 3TC, patients had significantly longer times to resistance compared to monotherapy patients even after adjusting statistically for the increased antiviral effect of the additional drugs.
A research team at Boston University School of Medicine has discovered that a synthetic compound significantly limits brain damage when administered after a stroke. Their finding, published September 16 in the Proceedings of the National Academy of Sciences, could lead to the development of drugs to treat stroke and traumatic brain or spinal cord injury. These new drugs could also slow the progression of ParkinsonÃs disease and ALS, more commonly known as ìLou GehrigÃs disease.î

A new study has uncovered the genetic wiring diagram underlying the infectiousness of Candida albicans, a fungus that causes thrush in babies, vaginal infections in women, and life-threatening infections in chemotherapy and AIDS patients. The study, led by Dr. Gerald R. Fink, Director of the Whitehead Institute for Biomedical Research, reveals that one key to CandidaÃs infectiousness lies in its ability to switch from a rounded form to filamentous forms. When the wiring diagram underlying this switch is inactivated, Candida infections are no longer deadly in mice.
