Objective: To compare neuropsychological scores in women infected with HIV, women infected with both HIV and hepatitis C, and uninfected subjects.
Background: Some, but not all, studies have demonstrated that dual infection with Hepatitis C virus (HCV) and HIV has worse effects on cognition than infection with HIV alone.
Design/methods: The Women's Interagency HIV Study is an ongoing prospective study of the natural history of HIV in women where participants are reevaluated every 6 months. In a cross-sectional analysis, we evaluated the effects of active HIV and HCV infections on scores on symbol-digit modalities test, the Stroop interference test, and trails A and B after controlling for age, ethnicity, education, depression, liver disease, and current or past substance abuse.
Results: Data were available for 1338 women-17.8 % had detectable hepatitis C virus and 67% were HIV seropositive. In fully adjusted general linear models, HCV viremia was not associated with scores on any of the cognitive tests.
Conclusions: In this large sample of women, active HCV infection was not associated with scores on a small battery of neuropsychological tests.

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.

Eight years after WHO adopted a resolution to eliminate hepatitis B by the year 2030, the disease remains a global public health concern, with vertical transmission of HBV being a major obstacle to this goal. Our study aimed to determine the HBV infection status of pregnant women in South Africa at a national level to evaluate the risk of vertical transmission and provide evidence for public health decision-making. We conducted HBsAg testing on 1,942 HIV-uninfected and 2,312 HIV-infected pregnant women from South Africa's public health sector in 2017, followed by HBeAg testing on HBsAg-positive samples.

Background: Update, the link between HIV infection and abnormal glucose metabolism (AGM) is still unclear. This study aims to investigate the impact of HIV infection on AGM, including insulin resistance (IR), impaired fasting glucose (IFG), and diabetes mellitus (DM).
Methods: A multicenter case-control study was conducted in Zhejiang province, China.

Bacterial sexually transmitted diseases (STDs) remain prominent in the United States among gay, bisexual, and other men who have sex with men (GBMSM). Doxycycline for post-exposure prophylaxis (DoxyPEP) is a regimen by which the antibiotic doxycycline is taken after sex to prevent bacterial STDs, such as, chlamydia, gonorrhea, and syphilis. Despite this, this study was conducted because there are a limited number of publications that describe GBMSM's knowledge of, and interest in, taking DoxyPEP and preferences regarding its implementation.

Natural amino acid polymorphisms in Tat may affect its functional properties and the course of HIV infection. The aim of this work is to analyze the marks of Tat consensus sequences in non-A6 HIV-1 variants characteristic of the Russian Federation, as well as study natural polymorphisms in Tat CRF63_02A6 and subtype B variants circulating in Russia.
