Researchers report promising results for a new chemoprevention gene therapy for preventing and treating pancreatic cancer, one of the most lethal and treatment-resistant forms of cancer.

Researchers have found that approximately one in ten US children uses one or more cough and cold medications during a given week. Pediatric cough and cold medications are widely marketed in the U.S. but surprisingly little is known about just how often they are used in children.

A new study in the Journal of the Science of Food and Agriculture shows that konjac gum and sesame seed extract may offer protection against different strains of E. coli and Salmonella bacteria.

Patients receiving rifampicin-based anti-tuberculosis therapy are more likely to experience virological failure when starting nevirapine-based antiretroviral therapy, an HIV treatment that is widely used in developing countries because of lower cost, than when starting efavirenz-based antiretroviral therapy, according to a study in the Aug. 6 issue of JAMA, a theme issue on HIV/AIDS.

Low-dose growth hormone treatment reduced abdominal fat deposits and improved blood pressure and triglyceride levels in a group of patients with HIV lipodystrophy -- a condition involving the redistribution of fat and other metabolic changes in patients receiving combination drug therapy for HIV infection -- but growth hormone treatment also appeared to increase blood glucose levels, particularly in those already exhibiting glucose intolerance.
