Young men who have sex with men (YMSM) have high rates of recreational drug use and binge drinking that are related to increases in unprotected sex and HIV risk. We describe the development of a community-level intervention focused on MSM ages 15 to 29 who identify as Black or White and who reported episodic use of alcohol and/or drugs. Intervention content included culturally-relevant role model stories and peer outreach. Outcome measures, including number of partners and a risk score indicating risk for HIV from protected or unprotected insertive or receptive anal sex, were examined over 36 months in a sample of YMSM in Philadelphia, the intervention site, and Baltimore, the comparison site...

We examined whether beliefs about antiretroviral (ART) efficacy and reinfection prospectively predicted subsequent condomless anal intercourse (CAI). Men who have sex with men in San Francisco (N = 773) were recruited for a longitudinal study using time-location sampling. HIV-negative men were more likely to have sero-discordant receptive CAI and HIV-positive men were more likely to have sero-discordant insertive CAI if they previously reported these behaviors at baseline and reported less concern about HIV transmission due to ART...

Given the rising HIV incidence in men who have sex with men (MSM) despite repeatedly proven effectiveness of oral HIV pre-exposure prophylaxis, behaviorally-congruent periodic dosing strategies, such as dosing microbicides as lubricants, are now in demand. Rectal microbicide gel studies largely administer gels using vaginal applicators, which have not been well-received and do not mimic lubricant use. We compared rectal gel manually dosed as lubricant to applicator dosing in five healthy, HIV-negative MSM who received 10 or 3...

OBJECTIVE: To analyze the construct validity and the internal consistency of the 12-item Bem Sex Role Inventory (BSRI-12) questionnaire and to study the association between gender stereotypes and sexual risk practices in men who have sex with men (MSM). METHODS: Cross-sectional study of 601 MSM who voluntarily and anonymously responded to an online survey on risk practices and gender stereotypes. The BSRI-12 was used to obtain gender stereotypes (masculine, feminine, undifferentiated and androgynous)...

Objective: This present study was to examine the prevalence and determinants of one-night-stand behavior among young men who have sex with men (YMSM). Methods: A total of 403 YMSM aged 16 to 25 were recruited through internet promotion, extending activity and HIV VCT in Wuhan. Data was gathered through anonymous questionnaire. Binary logistic regression was used to examine factors associated with one-night-stand behavior. Results: Of the 398 YMSM, 48.99% (195/398) reported having had casual sex in the last 6 months...

This study aimed to assess the level of condomless sex advertised online by private sex workers (PSW) in Sydney. In 2015, 750 online profiles of PSW, including 339 female, 53 male and 39 transgender PSWs, were reviewed. It was found that PSWs advertise protected anal and vaginal sex. However, 50% of female PSW advertised condomless oral sex. Age less than 25 years was associated with advertised condomless oral sex (odds ratio 1.56; 95% confidence interval 1.03-2.37; P=0.037). Online platforms are widely used for advertising, especially by female PSWs...

Background: Regular sexual partnerships among gay and bisexual men (GBM) who practice condomless anal intercourse (CLAI) have not been well characterised in terms of partnership type, HIV seroconcordance and risk of HIV transmission. Primarily sexual regular partnerships, although commonly reported by gay men, have largely been ignored in research and HIV prevention. Among regular partners reporting CLAI with each other, we determined factors differentiating romantic or committed relationships from partnerships organised primarily around sex ('fuckbuddies') and estimated the proportion of CLAI presenting risk for HIV transmission...

Current evidence suggests that anal intercourse (AI) during sex work is common in sub-Saharan Africa, but few studies investigated the contribution of heterosexual AI to HIV epidemics. Using a respondent-driven sampling survey of female sex workers (FSW) in Abidjan (2014), we estimated AI prevalence and frequency. Poisson regressions were used to identify AI determinants. About 20% of FSW (N = 466) engaged in AI during a normal week (95% confidence intervals: 15-26%). Women who performed AI were generally younger, had been selling sex for longer, were born in Côte d'Ivoire, reported higher sex-work income, more frequent sex in public places, and violence from clients than women not reporting AI...

The Medaka Extended One-Generation Test (MEOGRT) was developed as a multi-generational toxicity test for chemicals, particularly endocrine disrupting chemicals. Briefly, 3 generations of Japanese medaka (Oryzias latipes) are exposed to a chemical over a 20-week period: 3-week in the parental generation (F0), 15-week in the first generation (F1), and 2-week in the second generation (F2). The present study reports the first MEOGRT results concerning branched isomer mixtures of 4-nonylphenol (NP). Adult F0 medaka exposed to NP at 5 actual concentrations (1...

Black gay, bisexual, and other men who have sex with men (BMSM) experience a disparate rate of HIV infections among MSM. Previous analyses have determined that STI coinfection and undiagnosed HIV infection partly explain the disparity. However, few studies have analyzed the impact of partner-level variables on HIV incidence among BMSM. Data were analyzed for BMSM who attended the Los Angeles LGBT Center from August 2011 to July 2015 (n = 1974) to identify risk factors for HIV infection. A multivariable logistic regression was used to analyze predictors for HIV prevalence among all individuals at first test (n = 1974; entire sample)...

BACKGROUND: Early treatment of acute HIV-1 infection (AHI) is beneficial for patients and could reduce onward transmission. However, guidelines on whom to test for AHI with HIV-1 RNA testing are lacking. METHODS: A risk score for possible AHI based on literature and expert opinion - including symptoms associated with AHI and early HIV-1 - was evaluated using data from the Amsterdam Cohort Studies among men who have sex with men (MSM). Subsequently, we optimized the risk score by constructing two multivariable logistic regression models: one including only symptoms and one combining symptoms with known risk factors for HIV-1 seroconversion, using generalized estimating equations...

Hepatitis A virus (HAV) is one of the most common infectious etiologies of acute hepatitis worldwide. The virus is known to be transmitted fecal-orally, resulting in symptoms ranging from asymptomatic infection to fulminant hepatitis. HAV can also be transmitted through oral-anal sex. Residents from regions of low endemicity for HAV infection often remain susceptible in their adulthood. Therefore, clustered HAV infections or outbreaks of acute hepatitis A among men who have sex with men and injecting drug users have been reported in countries of low endemicity for HAV infection...

BACKGROUND: Our next generation sequencing (NGS)-based human papillomavirus (HPV) genotyping assay showed a high degree of concordance with the Roche Linear Array (LA) with as little as 1.25 ng formalin-fixed paraffin-embedded-derived genomic DNA in head and neck and cervical cancer samples. This sensitive genotyping assay uses barcoded HPV PCR broad-spectrum general primers 5+/6+ (BSGP)5+/6+ applicable to population studies, but it's diagnostic performance has not been tested in cases with multiple concurrent HPV infections...

BACKGROUND: Over the last decade, the causal link between human papillomavirus (HPV) infection and squamous cell carcinoma of the anus (SCCA) has been well described. Because HPV infection in one site is often associated with other sites of infection, it then follows that patients with SCCA may have an increased risk of additional HPV-related cancers. Identifying and targeting at-risk sites through cancer screening and surveillance may help to guide best practices. The current study sought to ascertain sites and risk of HPV-related second primary malignancies (SPMs) in survivors of SCCA...

Among 485 young black men who have sex with men recruited in Jackson, MS, 90-day anal sexual exposure significantly predicted rectal infection, but 19.4% of rectal infections would have been missed among men denying receptive anal sex. Reports of consistent condom use were associated with lower infection rates only in men reporting insertive anal sex.

BACKGROUND: Rectal sexually transmitted infections (STI) have been associated with human immunodeficiency virus (HIV) diagnosis, but inferring a causal association requires disentangling them from receptive anal intercourse (RAI). METHODS: We conducted a stratified case-control study by frequency matching 4 controls to each case within year using clinical data from men who have sex with men (MSM) attending the Seattle STD Clinic 2001 to 2014. Cases were MSM with a new HIV diagnosis and negative HIV test at 12 months or less...

The fermentation hypothesis for animal signalling posits that bacteria dwelling in an animal's scent glands metabolize the glands' primary products into odorous compounds used by the host to communicate with conspecifics. There is, however, little evidence of the predicted covariation between an animal's olfactory cues and its glandular bacterial communities. Using gas chromatography-mass spectrometry, we first identified the volatile compounds present in 'pure' versus 'mixed' anal-gland secretions ('paste') of adult meerkats (Suricata suricatta) living in the wild...

BACKGROUND: Women who inject drugs and who also exchange sex are at increased risk for HIV infection, but data on this population in the United States remain sparse. METHODS: This study assessed the prevalence of exchanging sex for money or drugs among women who inject drugs using data from the 2009 US National HIV Behavioral Surveillance (NHBS) system. Prevalence of being HIV-positive (testing positive in NHBS), HIV-positive-unaware (reporting being HIV-negative or unknown status but testing positive in NHBS), and risk behaviors and use of services were compared between women who did and did not exchange sex...
