Time Since First Acting on Same-Sex Attraction and Recreational Drug Use among Men Who Have Sex With Men (MSM): Is There an Effect of "Gay Age"?

Background: Men who have sex with men (MSM) have higher rates of substance use compared to men who have sex with women. Among MSM, drug use is linked to higher-risk sexual behavior and acquisition of HIV and other sexually transmitted infections.

Objectives: We hypothesize that time since first acting on one's same sex attraction, or one's "gay age", could be predictive of drug using behavior.

Large Cluster of Neisseria meningitidis Urethritis in Columbus, Ohio, 2015.

Background: Neisseria meningitidis (Nm) is a Gram-negative diplococcus that normally colonizes the nasopharynx and rarely infects the urogenital tract. On Gram stain of urethral exudates, Nm can be misidentified as the more common sexually transmitted pathogen Neisseria gonorrhoeae.

Methods: In response to a large increase in cases of Nm urethritis identified among men presenting for screening at a sexually transmitted disease clinic in Columbus, Ohio, we investigated the epidemiologic characteristics of men with Nm urethritis and the molecular and phylogenetic characteristics of their Nm isolates.

Group Sex and Prevalent Sexually Transmitted Infections Among Men Who Have Sex with Men.

We evaluated the direct relation between group sex and prevalent sexually transmitted infections (STI) in a cross-sectional study of men who have sex with men (MSM) presenting at an urban STI clinic in the Midwestern US. Among 231 men who enrolled and reported that they have sex with men, we collected behavioral data using a combination of interviewer and self-administered surveys and extracted STI data from electronic health records. We used modified Poisson regression to examine the unadjusted and adjusted associations between group sex participation and prevalent STI.

Body image and sexually transmissible infection prevalence among men who have sex with men.

Compared with men who have sex with women, some evidence suggests that men who have sex with men (MSM) have increased prevalence of body image dissatisfaction. MSM also have a higher prevalence of sexually transmissible infections (STIs) than other population groups. As part of a cross-sectional study, body image among 104 MSM using the standardised, validated Male Body Attitudes Scale was assessed.

A blinded, randomized controlled trial of high-dose vitamin D supplementation to reduce recurrence of bacterial vaginosis.

Objective: Low serum vitamin D levels have been associated with increased prevalence of the reproductive tract condition bacterial vaginosis (BV). The objective of this trial was to evaluate the effect of high-dose vitamin D supplementation on BV recurrence.

Study Design: This randomized, placebo-controlled, double-blinded trial enrolled 118 women with symptomatic BV from an urban sexually transmitted disease clinic (clinicaltrials.
