Objectives: Human immunodeficiency virus (HIV) preexposure prophylaxis (PrEP) is an effective HIV prevention tool. Expanding PrEP access and utilization is made possible by incorporating it into primary care practice. This study explored the barriers in and attitudes toward prescribing PrEP to adults among primary care providers (PCPs) in Alabama, a priority HIV jurisdiction with low PrEP uptake.

Background: Twice-yearly subcutaneous lenacapavir has been shown to be efficacious for prevention of HIV infection in cisgender women. The efficacy of lenacapavir for preexposure prophylaxis (PrEP) in cisgender men, transgender women, transgender men, and gender-nonbinary persons is unclear.

Methods: In this phase 3, double-blind, randomized, active-controlled trial, we randomly assigned participants in a 2:1 ratio to receive subcutaneous lenacapavir every 26 weeks or daily oral emtricitabine-tenofovir disoproxil fumarate (F/TDF).

Objectives: We aimed to investigate the early natural history of in men recently testing positive for this infection by a nucleic acid amplification test (NAAT). We hypothesised that 50% of men would spontaneously resolve their infection (in the absence of treatment) on repeat NAAT.

Methods: Men ages ≥18 years at the Jefferson County Health Department Sexual Health Clinic testing positive for by NAAT during standard-of-care (SOC) within the past 30 days and presenting to the clinic for treatment were approached.

Introduction: The aetiology of bacterial vaginosis (BV), a biofilm-associated vaginal infection, remains unknown. Epidemiologic data suggest that it is sexually transmitted. BV is characterised by loss of lactic acid-producing lactobacilli and an increase in facultative and strict anaerobic bacteria.

We present a case of recurrent, cutaneous mpox with coinfection of disseminated varicella zoster in an immunocompromised patient with poorly controlled HIV. This case demonstrates the importance of maintaining a high index of suspicion for mpox despite prior infection and vaccination, as suboptimal immune response is possible in immunocompromised patients, and also noting the potential for coinfection necessitating timely diagnosis and appropriate testing.

Purpose Of Review: Bacterial vaginosis (BV) is the most common vaginal infection worldwide, but most research has been conducted in premenopausal women. After menopause, endogenous estrogen production decreases, often leading to the genitourinary syndrome of menopause (GSM), characterized by vulvovaginal dryness and irritation. The estrogen-deficient postmenopausal state results in an elevated vaginal pH and depletion of vaginal lactobacilli.

Objectives: Bacterial vaginosis (BV) and trichomoniasis are the most common causes of vaginitis. Both infections are associated with increased risk of acquisition and transmission of HIV and other sexually transmitted infections as well as adverse reproductive health outcomes. Co-infection is common, with rates ranging from 60% to 80%.

Background: HIV and sexually transmitted infections (STIs) disproportionally affect transgender women in the United States, particularly in the Southeast where rates of HIV and bacterial STIs are especially high. Despite the high HIV/STI burden among transgender women, their engagement in sexual healthcare services, including HIV/STI testing, is low. Understanding reasons for this disconnect is essential in developing HIV/STI prevention efforts for this population, especially in the Southeastern US, where access to affirming sexual healthcare providers and resources is limited.

Counseling patients on their HIV test results is an important part of undergraduate and graduate medical education. However, many trainees and physicians feel ill prepared to counsel patients on potentially distressing results. We present a case involving early disclosure of a false-positive HIV screening test result to a patient and the downstream effects of this premature disclosure.

Transgender and gender-diverse populations have unique medical and psychosocial needs. It is important that clinicians address these needs with a gender-affirming approach in all aspects of health care for these populations. Given the significant burden of HIV experienced by transgender people, such approaches in providing HIV care and prevention are essential both to engage this population in care and to work toward ending the HIV epidemic.

Introduction: The effect of testosterone (T) therapy on the vaginal microbiota of transgender men (TGM) is not well characterised, although one cross-sectional study comparing the vaginal microbiota of cisgender women to TGM on T≥1 year found that, in 71% of the TGM, the vaginal microbiota was less likely to be -dominated and more likely to be enriched with >30 other bacterial species, many associated with bacterial vaginosis (BV). This prospective study aims to investigate changes in the composition of the vaginal microbiota over time in TGM who retain their natal genitalia (ie, vagina) and initiate T. In addition, we will identify changes in the vaginal microbiota preceding incident BV (iBV) in this cohort while investigating behavioural factors, along with hormonal shifts, which may be associated with iBV.

Article Synopsis
  • Despite being effective for HIV prevention, Pre-exposure Prophylaxis (PrEP) is not widely used in the US, particularly among high-risk groups, potentially due to stigma associated with PrEP use.
  • Researchers created a survey to explore different types of PrEP-related stigma and their impact on adherence to the medication, focusing on current users from two clinics in Birmingham, Alabama.
  • Findings showed that only internalized stigma was linked to lower self-reported adherence, suggesting that stigma may hinder PrEP use by affecting users' confidence in their adherence to the treatment.

Women are disproportionately affected by sexually transmitted infections (STIs) throughout life. In addition to their high prevalence in women, STIs have debilitating effects on female reproductive health due to female urogenital anatomy, socio-cultural and economic factors. In this Review, we discuss the prevalence and impact of non-HIV bacterial, viral and parasitic STIs on the reproductive and sexual health of cisgender women worldwide.

As acceptance of transgender and gender diverse individuals continues to increase, gender-affirming surgery, a cornerstone in the management of gender dysphoria, is becoming more readily available. HIV and sexually transmitted infections (STIs) disproportionately affect these populations, but there are limited epidemiologic and management data on STIs in people who have undergone gender-affirming genital surgery such as vaginoplasty. This review will provide clinicians with anatomical details about the various vaginoplasty procedures currently being performed, complications associated with these procedures, and an overview of the current literature describing HIV/STI epidemiology among transfeminine individuals who have undergone vaginoplasty.

Background: Little is known regarding human immunodeficiency virus (HIV)/sexually transmitted infection (STI) testing preferences for location, staffing, and hours of operation among Young Black men who have sex with men (YBMSM) in the Southeastern United States, a population at high risk for HIV/STIs. We used a discrete choice experiment to explore these preferences.

Methods: Young Black men who have sex with men ages 16 to 35 years in Birmingham, AL and Jackson, MS completed online surveys evaluating their preferences (best/worst) for HIV/STI testing locations, staffing, hours, method of results notification, and cost.
