En este artículo se reconstruye una escena social que permite vincular las relaciones homoeróticas con un contexto cultural y una situación histórico-política particulares: las comunidades de migrantes mexicanos en Estados Unidos. Utilizamos los discursos de diversos actores sociales para recalcar que el sexo entre hombres se vincula con configuraciones socioculturales específicas. Se analizan estos discursos para mostrar cómo se construye y cómo se contrapone un modelo de comprensión de la sexualidad fundamentado en la identidad, utilizado por las organizaciones dedicadas a la prevención del SIDA, con otro estratégico y no identitario construido por los hombres migrantes. A partir de esta contraposición se elabora una crítica tanto al sustrato epistemológico de la categoría de hombres que tienen sexo con hombres como la lógica que impera en los discursos preventivos, que son leídos como formulaciones del dispositivo de la sexualidad occidental, que pide verdad y coherencia a la sexualidad de los sujetos.

Between 1981 and 1999, more than 110,00 cases of the acquired immunodeficiency syndrome (AIDS) have been reported in California, of whom nearly 70,000 patients have died. Since 1983, the University of California has funded basic, clinical, social, and behavioral research on the human immunodeficiency virus (HIV)/AIDS through the University wide AIDS ResearchProgram (UARP). Major accomplishments of UARP-supported research include the isolation and characterization of HIV, the detection and elimination of HIV in blood clotting factor VIII, and in early studies, the demonstration of the rapid production and turnover of HIV in the blood of infected persons. Together with its advisory group, the University wide Task Force on AIDS, UARP convenes an annual meeting that provides an opportunity for the exchange of new information on HIV/AIDS in California. Participants include bench scientists, clinicians, policymakers, outreach workers, community-based organizations, and members of affected communities. Most of the studies presented at the UARP conference are in their early stages and modestly funded. While some go on to receive larger federal grants, others are quickly integrated into new interventions or investigations. In this issue of wjm, we share highlights of the 3rd AnnualConference on AIDS Research inCalifornia.† The plenarytheme for the year 2000 was “Early Events and Intervention in HIVInfection.” Although the recent and ongoing advances in highly active antiretroviral therapy are well known, the meeting provided a fertile venue for presenting other innovative areas for treatment and prevention.

We describe the anatomic and histologic presentation and prognosis of non-Hodgkin's lymphoma (NHL) among people with AIDS (PWA) and determine their contribution to the NHL burden. We linked AIDS and cancer registries in selected areas of the United States and compared NHL sites and histologies in PWA and non-PWA, after adjusting for age, sex and ethnicity. Among 51,033 PWA, we found 2,156 cases of NHL (4.3%). Half of NHL cases occurring post-AIDS were not reported to AIDS registries. NHL was part of an AIDS-defining condition for 3.2% of all PWA; the relative risk of NHL with 3.5 years of another AIDS diagnosis was 165-fold compared to non-PWA within the cancer surveillance system. Of NHLs, 39% were high grade (vs. 12% among non-PWA), 60% were nodal (vs. 74% among non-PWA) and 15% had brain primaries (vs. 1% among non-PWA). Excluding brain sites, extranodal sites were still 20% more common than expected. Relative risk was elevated for all histologic types, with the risk ranging from 652-fold for high-grade diffuse immunoblastic tumors and 261-fold for Burkitt's lymphomas to 113 for intermediate-grade lymphoma to 14-fold for low-grade lymphoma. Survival among PWA with NHL was poor, and tumor grade had little impact. In high-risk AIDS areas, AIDS-related NHLs constitute a major share of the NHL burden. We conclude that NHL risk is considerably under-estimated in AIDS registry data. The major differences between PWA and non-PWA were the high frequency of brain lymphoma and the increase in high-grade lymphomas in PWA. However, the grade of NHL did not influence the prognosis among PWA with lymphoma. The increasing risk of NHL in PWA has contributed substantially to the general increase in NHL rates in the United States since 1981.

To evaluate the vulnerability for STI/HIV among Mexican indigenous women in common law marriage with men who practice sex without condom.Ethnography study undertaken in indigenous villages of Michoacán and Oaxaca, Mexico, in February 2004 and December 2005. These rural communities are characterized by high migration rates, extreme poverty and HIV/AIDS cases. An in-depth interview was applied to transient migrants (24), indigenous women (33), local authorities (20) and health providers (14).Rural propagation of STI/HIV is associated to sexual female initiation and mostly to migrants' fear their concubines will have extramarital sex during their absence. Impregnating their wives and the resulting childcare is one of the men's resources for controlling their concubines.Return migration implies vulnerability for indigenous women in the rural communities studied whose sexuality has a strong reproductive profile. It is necessary to develop prevention campaigns against STI/HIV taking into account male sexual identities to improve women rights to sexual and reproductive health.
