Objective: Men who have sex with men (MSM) are disproportionately affected by HIV in Greece. However, research on HIV incidence in this group is lacking. This study aimed at estimating HIV incidence among MSM in Athens, Greece.
Methods: The analysis included routinely collected data between January 2013-June 2015 from adult MSM who visited a community-based facility (Ath Checkpoint) at least twice and were non-reactive to the rapid INSTI HIV-1/HIV-2 assay at baseline. HIV conversion rates were calculated by dividing the number of clients who became reactive by the person-years of observation. All statistical analyses including Poisson regression models were conducted in STATA 14.
Results: A total of 1,243 MSM contributed 1,102.50 person-years (py). The overall (per 100 py) conversion rate was 3.99 (95% CI: 2.97-5.36). In multivariable analyses, age less than 30 years was associated with an increased risk of HIV conversion (rate ratio: 2.01; 95% CI: 1.08-3.76).
Conclusions: This analysis shows high rates of HIV conversion among MSM who repeatedly visit a community-based testing site. Ath Checkpoint could contribute to HIV surveillance and identify a high-risk group that could benefit from essential health interventions.

Background: For decades, poor treatment options and low-quality evidence plagued care for patients with rifampin-resistant tuberculosis. The advent of new drugs to treat tuberculosis and enhanced funding now permit randomized, controlled trials of shortened-duration, all-oral treatments for rifampin-resistant tuberculosis.
Methods: We conducted a phase 3, multinational, open-label, randomized, controlled noninferiority trial to compare standard therapy for treatment of fluoroquinolone-susceptible, rifampin-resistant tuberculosis with five 9-month oral regimens that included various combinations of bedaquiline (B), delamanid (D), linezolid (L), levofloxacin (Lfx) or moxifloxacin (M), clofazimine (C), and pyrazinamide (Z).
Exploring the relationship between established HIV risk factors and depressive symptoms amongst young women without HIV in two sites in South Africa.

Purpose: Adolescent girls are at high risk for depression and human immunodeficiency virus (HIV) acquisition. Poor mental health can increase vulnerability to risky sexual behaviours. Therefore, this study aims to determine the prevalence of depressive symptomology and explore the convergence of HIV risk factors with depressive symptoms amongst cis-gender adolescent girls and young women (AGYW) in rural KwaZulu-Natal (KZN) and peri-urban Western Cape (WC) communities in South Africa.

Many HIV clinics with poor IT-infrastructure are unable to report data on individuals in care with HIV, on antiretroviral treatment (ART) and virologically suppressed (VS), with the aim of monitoring the HIV Continuum of Care to estimate efficacy of HIV treatment programmes. We developed an estimation-tool, ESTIHIV, and determined the minimal data required for a random sample, to produce representative estimates, with a specified level of precision, of people with HIV on ART and VS. For proof of concept, 8852 HIV positive persons from seven clinics in seven different countries, with a follow-up visit during 2017, were included.

Background: Malaria and HIV are leading causes of death in Africa, including Cameroon. Antiretroviral therapy (ART) is expected to boost immunity and reduce vulnerability to opportunistic infections. Reports on comorbidities including malaria are common in Cameroon.

Anaemia and thrombocytopenia are blood-related irregularities linked to an increased likelihood of disease progression, leading to death in people living with human immunodeficiency virus 1 (PLHIV). Severe clinical conditions associated with human immunodeficiency 1 (HIV-1) infection may be related to blood irregularities among PLHIV. The study aimed to examine the factors correlated with blood irregularities among PLHIV receiving antiretroviral treatment in West Papua.
