Harnessing Big Heterogeneous Data to Evaluate the Potential Impact of HIV Responses Among Key Populations in Sub-Saharan Africa: Protocol for the Boloka Data Repository Initiative.

Background: In South Africa, there is no centralized HIV surveillance system where key populations (KPs) data, including gay men and other men who have sex with men, female sex workers, transgender persons, people who use drugs, and incarcerated persons, are stored in South Africa despite being on higher risk of HIV acquisition and transmission than the general population. Data on KPs are being collected on a smaller scale by numerous stakeholders and managed in silos. There exists an opportunity to harness a variety of data, such as empirical, contextual, observational, and programmatic data, for evaluating the potential impact of HIV responses among KPs in South Africa.

Use of patient portals to disclose STI test histories to sex partners among U.S. men who have sex with men: A call for research and guidance.

Background: This study investigates the use of patient portals for disclosing sexually transmitted infection (STI) test result histories to sexual partners among men who have sex with men (MSM) in the United States.

Methods: Using data from the 2022-2023 American Men's Internet Survey, this cross-sectional analysis examined demographic, behavioral, and healthcare-related factors associated with MSM's utilization of patient portals for sharing STI test results. Participants ( = 2601) were surveyed on portal use, STI testing frequency, and partner disclosure practices.

Suspected Mpox Symptoms and Testing in Men Who Have Sex With Men in the United States: Cross-Sectional Study.

Background: The 2022 mpox outbreak in the United States disproportionately affected gay, bisexual, and other men who have sex with men (GBMSM). Uptake of mpox testing may be related to symptomology, sociodemographic characteristics, and behavioral characteristics.

Objective: This study aimed to describe suspected mpox symptoms and testing uptake among a sample of GBMSM recruited via the internet in the United States in August 2022.

Association between homelessness and PrEP uptake among men who have sex with men: Results from the American Men's Internet Survey, 2017-2021.

Background: Gay, bisexual, and other men who have sex with men (GBMSM) are disproportionately affected by housing insecurity across the US. This study examined the association between homelessness and uptake of pre-exposure prophylaxis (PrEP) for HIV prevention among GBMSM in the United States and investigated the modifying effect of injection drug use.

Methods: 47,750 cisgender GBMSM who participated in the American Men's Internet Survey from 2017 to 2021 and who self-reported not living with HIV were included in this secondary, cross-sectional analysis.

Evidence for intrinsic DNA dynamics and deformability in damage sensing by the Rad4/XPC nucleotide excision repair complex.

Altered DNA dynamics at lesion sites are implicated in how DNA repair proteins sense damage within genomic DNA. Using laser temperature-jump (T-jump) spectroscopy combined with cytosine-analog Förster Resonance Energy Transfer (FRET) probes that sense local DNA conformations, we measured the intrinsic dynamics of DNA containing 3 base-pair mismatches recognized in vitro by Rad4 (yeast ortholog of XPC). Rad4/XPC recognizes diverse lesions from environmental mutagens and initiates nucleotide excision repair.
