Until relatively recently, HIV was recruited almost exclusively the impact of men who have sex with men in Mexico. But this is not the case. The proportion of female cases has increased steadily over the years from 3 % in 1987 to over 27 % in 2008.The first research results were presented in abstract form by June 10 UCSF NanoEngineer Shuvo Roy, Ph.D., during the annual conference of the American Society for Artificial Internal Organs in Washington, DC. Roy has also presented the first test results show that silicon-based membranes are compatible with human blood and therefore provide viable options in the filters implanted devices as a model for the team’s implantable artificial kidney

Previous research had shown that Mujer Segura was effective in a study of 600 sex workers in Tijuana and Ciudad Juarez, but questions lingered about the comparative accessibility. The cost of the HIV epidemic worldwide is huge: more than $ 10 billion. In Mexico, HIV-related costs exceed $ 270 million a year, 88 % of what is happening to antiretroviral drugs for patients with active disease. Could a program like Mujer Segura reduce the overall costs of prevention of HIV infections in the first place?

‘The cost for each procedure is less than $ 200, making it very beneficial, especially when you consider the costs of treating HIV in reality,’ said Jose L. Burgos, MD, a project scientist in the Division of global public health, the department of medicine at UC San Diego, a member of the faculty of the School of Medicine of the Universidad Autonoma de Baja California and the University of Xochiacalco in Tijuana, Mexico. Burgos was also the leader of the study.

The increasing prevalence of HIV and sexually transmitted diseases is particularly relevant among sex workers. For example, a 1997 study estimated the prevalence of HIV among sex workers in Mexico to 0.6 %.

The researchers modeled the effect of a thousand prostitutes are trained Mujer Segura Intervention times a year and not at all.7 months life expectancy adjusted or added QALE as compared to sex workers who received no intervention . For sex workers who received annual interventions, there have been 29 other cases of HIV averted and 4.5 months QALE.

‘These results are important,’ said Thomas Patterson, PhD, professor of psychiatry at the Faculty of Medicine, UC San Diego. ‘Too often, good research is sitting on a shelf, not implemented, because it is thought not to be profitable. This study shows that a relatively inexpensive intervention program can significantly affect the incidence of HIV and sexually transmitted diseases in a population at high risk. ‘

The results will be published online by the journal PLoS One on June 30.

Programs to reduce HIV and sexually transmitted diseases among sex workers is critical, said Rodriguez CENSIDA because they help to reduce transmission of the disease among high-risk groups and general population in areas where concentrated epidemics. Tijuana and Ciudad Juarez, where researchers from UC San Diego have long focused their studies, are obvious target areas, because sex is a quasi-judicial and prosperous.

The value of the program is strengthened by its target audience, said Carlos Magis Rodriguez, director of research for the Center Prevenci ny para el control HIV / AIDS , the arm of the Mexican Ministry of Health that focuses on HIV-AIDS.

Using a sophisticated modeling system, researchers have studied how a hypothetical group of 1,000 sex workers in the United States and Mexico border region would respond to a behavioral intervention program called Mujer Segura and tested previously healthy woman.

About 35 minutes in length, Mujer Segura uses motivational techniques to encourage sex workers to use safer sex practices, and teaches an improved ability to negotiate condom use with clients seeking unprotected sex.
