Passivos, ativos and versáteis: men who have sex with men, sexual positions and vulnerability to HIV infection in the northeast of Brazil

Coming to Voice as Total Top or Total Bottom: Autobiographical Acts and the Sexual Politics of Versatility on Reddit

For gay, bisexual, and men who have sex with men (GBMSM), sexual versatility encompasses both insertive (top) and receptive (bottom) sexual practices. By contrast, "total top" and "total bottom" roles are often marginalized by those who advocate versatile roles for GBMSM. This article explores how GBMSM "come to voice" as total tops and total bottoms on the social media platform, Reddit. Reading posts and comments as autobiographical acts, the article analyses how total tops and bottoms assert the validity of their claim to sexual knowledge as total top or total bottom while negotiating the sexual politics of versatility on Reddit and beyond.

Sexual Practices and Predisposition to PrEP Use Among Men Ages 50 Years and Older Who Have Sex With Men: A Cross-Sectional Study

ABSTRACT

This study aimed to evaluate the sexual practices of men ages 50 years or older who have sex with men (MSM) and factors influencing their predisposition to use preexposure prophylaxis (PrEP). An analytical cross-sectional study was conducted in Brazil and Portugal with 718 MSM. Of these, 278 (38.7%) were categorized as being at high risk for HIV based on the HIV Incidence Risk Index (HIRI), and 418 (58.2%) expressed a predisposition to use PrEP. Overall, sociodemographic factors and specific sexual practices increased the likelihood of being classified as high risk for HIV, particularly sexual position and sexual activity. However, factors that influenced the predisposition to use PrEP included age group, receptive anal sex, knowledge of postexposure prophylaxis, high HIRI score, and a history of syphilis. These findings underscore the urgent need for health services to provide comprehensive and adequate attention to the realities of this population, considering its complexities and specificities.

Sobre descrições, retificações e objetividade científica: reflexões metodológicas a partir de uma pesquisa sobre condutas sexuais e HIV/aids entre homens com práticas homossexuais

Resumo Este ensaio reflete sobre a positividade de conhecimentos produzidos por abordagens etnográficas, a partir da discussão dos meandros de uma pesquisa sobre homens que se relacionam sexualmente com outros homens e vulnerabilidade ao HIV/aids. Propõe como falsa a oposição entre metodologias explicativas e compreensivas, uma vez que ambos os princípios estão presentes, em maior ou menor grau, em todas as investigações em ciências humanas e sociais. Nessa linha, põe em xeque critérios de cientificidade do “senso comum científico” que fazem o uso da matemática como o demarcador. Exemplifica como a descrição crítica do próprio ato de pesquisar e das retificações sobre os obstáculos ao conhecimento, identificados no próprio caminho, conferem objetividade aos conhecimentos produzidos. O diferencial etnográfico em relação a outras abordagens de ênfase compreensiva é a explicitação da própria experiência dos pesquisadores no campo como recurso crítico e analítico.

Epidemiological risk factors associated with primary infection by Epstein-Barr virus in HIV-1-positive subjects in the Brazilian Amazon region

To identify the prevalence and risk factors for primary Epstein–Barr virus (EBV) infection in human immunodeficiency virus (HIV)-1-positive adult treatment-naïve patients between January 2018 and December 2019 in a state of the Brazilian Amazon region. A total of 268 HIV-1 positive patients and 65 blood donors participated in the study. Epidemiological data were obtained from medical records and through a designed questionnaire. EBV infection was screened by the semiquantitative detection of anti-viral capsid antigen (VCA) EBV IgM and IgG, followed by molecular detection of the EBNA-3C gene. The plasma viral loads of HIV-1 and EBV were quantified using a commercial kit. The prevalence of primary coinfection was 7.12%. The associated risk factors were education level, family income, history of illicit drug use and sexually transmitted infections, homosexual contact and condom nonuse. Approximately 58.5% had late initiation of highly active antiretroviral therapy, which influenced the risk of HIV-EBV 1/2 multiple infection (odds ratio (OR): 4.76; 95% CI 1.51–15.04) and symptom development (p = 0.004). HIV viral load was associated with patient age (OR: 2.04; 95% CI 2.01–2.07; p = 0.026) and duration of illicit drug use (OR: 1.57; 95% CI 1.12–2.22; p = 0.0548). EBV viral load was associated with younger age (OR: 0.82; 95% CI 0.79–1.03; p = 0.0579). The replication of both viruses was associated with symptom development (HIV = OR: 2.06; 95% CI 1.22–3.50; p = 0.0073; EBV = OR: 8.81; 95% CI 1–10; p = 0.0447). The prevalence of HIV/EBV coinfection was lower than that observed in other studies, and social vulnerability and promiscuous sexual behavior were associated risk factors. A long time of HIV-1 infection, without therapy, influenced the risk of coinfection and disease progression. The viral loads of both viruses may be associated with some epidemiological aspects of the population.
