viernes, octubre 21st, 2011

A new study uses a mathematical model to predict the potential impact of expanding treatment to discordant couples on controlling the global HIV epidemic– in these couples one partner has HIV infection and the other does not. The research conducted at ICAP at Columbia University’s Mailman School of Public Health and the Semel Institute of Neuroscience and Human Behavior at University of California in Los Angeles (UCLA) is the first to predict the effect of the expansion of such treatment in couples on the HIV epidemic in certain African countries.

Contraceptive Used in Africa May Double Risk of H.I.V.

martes, octubre 11th, 2011

The most popular contraceptive for women in eastern and southern Africa, a hormone shot given every three months, appears to double the risk the women will become infected with H.I.V., according to a large study published in The Lancet Infectious Diseases on 4 October 2011.

miércoles, junio 8th, 2011

Combination antiretroviral therapy has led to a major reduction in HIV-related mortality and morbidity. However, HIV still cannot be cured. With the absence of an effective prophylactic or therapeutic vaccine, increasing numbers of infected people, emerging new toxicities secondary to combination antiretroviral therapy and the need for life-long treatment, there is now a real urgency to find a cure for HIV.
