BACKGROUND: With increasing use of non-condom-based HIV risk reduction strategies by gay and bisexual men (GBM), we compared occasions of condomless anal intercourse with casual partners (CLAIC) that resulted in HIV transmission and similar occasions when HIV transmission did not occur. METHODS: We compared two demographically similar samples of Australian GBM. The HIV Seroconversion Study (SCS) was an online cross-sectional survey of GBM recently diagnosed with HIV...

Ninety-five percent of precursor lesions -high-grade squamous intraepithelial lesions (HSIL) and anal intraepithelial neoplasms (AIN)- and their progression to squamous anal cancer (AC) are induced by high-risk HPV (HR-HPV) serotypes 16 and 18. Their incidence is higher particularly in HIV-infected male patients who have sex with other males (HIV-MSM) (144/100,000/patients/year).

BACKGROUND: Human immunodeficiency virus self-testing (HIVST) holds great promise for reaching high-risk key populations who do not access facility-based services. We sought to characterize unsupervised HIVST implementation among men who have sex with men in China. METHODS: We conducted a nationwide online survey in China. Eligible men were at least 16 years, had anal sex with a man, and had recent condomless sex. We assessed benefits (first-time testing, increased testing frequency, confirmatory testing) and potential harms (coercion, violence, suicidality) of HIVST...

This study explored labeling of penile-anal intercourse (PAI), manual-anal (MA), and oral-anal (OA) behaviors as having "had sex" among heterosexual men and women with such experience residing in the United States (n = 3,218). Adult men and women completed an online questionnaire assessing sexual behaviors and whether each counted as having had sex. With the exception of anal intercourse, there was high variation in whether a behavior was labeled having had sex. There was not consensus on which anal sexual behaviors constituted having had sex, with attitudes varying across age, gender, and behavioral experience...

Latino men who have sex with transgender women make up an overlooked sector of the population that requires more attention than is currently given in sexuality and gender studies, particularly in regard to their non-commercial, long-term sexual and romantic relationships with transgender women. Sixty-one sexual histories were selected for this qualitative analysis from a larger study on Latino male bisexuality in the New York City metropolitan area. Findings suggest that participants' sexual and gender scripts with transgender women are strongly regulated by heteronormativity...

BACKGROUND: Sri Lanka has recently completed an HIV prevention project for most-at-risk populations (MARP) under the Global Fund. The intervention includes delivery of a HIV prevention package (HPP) to men who have sex with men (MSM) that includes provision of: (1) knowledge about sexually transmitted infections (STI); (2) HIV knowledge; (3) MSM-tailored leaflets; (4) condom/dildo demonstration; (5) provision of condoms; and (6) clinic escorts. MSM who received services 1-5 in the HPP are defined as 'reached'...

Background: Definitive chemoradiotherapy (CRT) is recommended by the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Anal Carcinoma for all patients with stage I anal canal cancer. Because these patients were not well represented in clinical trials establishing CRT as standard therapy, it is unclear whether NCCN recommendations are being closely followed for stage I disease. This study identified factors that predict for NCCN Guideline-concordant versus NCCN Guideline-discordant care. Methods: Using the National Cancer Data Base, we identified patients diagnosed with anal canal carcinoma from 2004 to 2012 who received concurrent CRT (radiotherapy [RT] 45...

Men who have sex with men (MSM) are a large high-risk population for HIV infection in recent years in China. A cross-sectional survey was conducted in Hangzhou, China, to determine rates of condomless anal intercourse (CAI), recent HIV testing (in the recent year) and associated factors using respondent-driven sampling. Questionnaires using face-to-face interviews were employed to collect data on sexual risk behaviors and HIV testing. Five hundred eleven MSM were recruited, of which 459 (89.8%) had anal intercourse in the past 6 months...

BACKGROUND: Gay, bisexual, and other men who have sex with men (GBMSM) in the United States remain disproportionately affected by human immunodeficiency virus (HIV). Yet their testing frequency is suboptimal and condomless anal sex (CAS) is increasing. Behavioral theories posit that information about HIV is a pivotal construct in individual risk reduction. However, measurements of knowledge have traditionally focused on ever hearing about HIV and being aware of the most common routes of spread...

Two new species of the genus Melanorivulus are herein described from the middle Rio Verde drainage, upper Rio Paraná basin, Mato Grosso do Sul, Brazil. Both new species are members of the Melanorivulus pictus clade, diagnosed by having ventral process of angulo-articular vestigial and flanks intense greenish blue or greenish golden to purplish blue above anal fin base in males. Melanorivulus nigropunctatus, new species, from wetlands of a small drainage tributary of right side of the Rio Verde, differs from all other congeners by possessing black dots over the head and body in both sexes and pectoral fin orange with a dark grey margin in males...

Pseudocrenilabrus pyrrhocaudalis sp. nov. is described from Lake Mweru in the upper Congo River drainage, on the border of the Democratic Republic of Congo and Zambia. This species, which appears to be endemic to the lake, lives in sympatry with P. philander. Pseudocrenilabrus pyrrhocaudalis sp. nov. is distinguished from P. philander in nuptial males by the presence of an orange colour on the ventral part of the body and the proximal parts of the anal and caudal fins, a broad band of bright white on the distal edge of anal and caudal fins, a uniform grey head and dorsum, and a subtruncate caudal fin...

A 19-year-old woman, who had been receiving hormone replacement therapy for 13 months before the diagnosis of mosaic Turner syndrome (46XXp-/45X), developed Crohn's colitis and erythema nodosum of the lower legs. Colonoscopy revealed an anal fistula and the presence of deep longitudinal ulcers with cobblestoning in the colorectum. Therapy with prednisolone and adalimumab was effective for the intestinal and skin lesions. To date, all seven case reports of Turner syndrome in Japan have also developed Crohn's disease after hormone therapy, suggesting a possible association of sex hormones in the pathogenesis...

We examined correlates of sexual risk among gay and bisexual men, who recently migrated from western and eastern African countries to the USA and lived in New York City and who are HIV negative or of unknown status. These men migrate from countries where same-sex sexuality is socially rejected and mostly illegal contributing to the motivation to migrate. Their background might predispose these men to engagement in sexual risk practices, while they are not specifically addressed in HIV prevention programming...

CONTEXT: The typical understanding of sexual debut as first vaginal intercourse is often irrelevant to sexual minority youth. Better understanding of sexual initiation patterns among these youth is necessary to inform efforts to safeguard their sexual and reproductive health. METHODS: Early sexual experiences were examined among 1,628 female and 526 male sexual minority participants in Waves 1 (1994-1995) and 4 (2008) of the National Longitudinal Study of Adolescent to Adult Health...

BACKGROUND: 3D-high definition anorectal manometry (3DARM) may aid the diagnosis of functional anorectal disorders, but data comparing asymptomatic and symptomatic subjects are scarce. We aimed to describe 3DARM values in asymptomatic volunteers and those with fecal incontinence (FI) or chronic constipation (CC), and identify which variables differentiate best these groups. METHODS: Asymptomatic subjects were stratified by sex, age, and parity. Those with FI or CC were included according to anorectal symptom questionnaires...

Young men who have sex with men (YMSM) are at increased risk for HIV and problematic alcohol use. Drinking motives are associated with alcohol use in cross-sectional studies, but their associations with alcohol use and condomless anal sex (CAS) at the event-level remain unclear. The current study examined these event-level associations in a sample of 189 YMSM who completed self-report measures on a daily or weekly basis for two months. Participants were recruited between August 2014 and April 2015 for a randomized trial designed to study behavioral reactivity in diary studies...
