Objectives: Worldwide, adult men experience an excess burden of tuberculosis (TB) disease compared with women, but few studies have examined sex differences in TB among people with HIV. In this study, we aimed to investigate sex differences in TB infection and disease among people with HIV in Rio de Janeiro, Brazil.
Design: Analysis of data from a randomized controlled trial and retrospective cohort study.
Methods: We analyzed data from two studies conducted between 2005 and 2017. The THRio Study (2005-2012) evaluated increasing tuberculin skin testing (TST) and TB preventive therapy (TPT), and Universal ART in Rio study (UnivART; 2010-2017) was a virtual cohort study of people with HIV and TB with data from four national electronic registries.
Results: Among 4606 people with HIV in THRio, 2992 (65.0%) had a TST placed and read, of whom 312 of 1865 (17%) males and 203 of 1127 (18%) females ( P = 0.37) had prevalent TB infection. TB disease incidence was higher among males compared with females overall [IRR 1.33, 95% confidence interval (95% CI) 1.04-1.69], among males compared with females who did not receive TPT [incidence rate ratios (IRR) 1.30, 95% CI 1.01-1.67], and among males compared with females on ART (IRR 1.64, 95% CI 1.17-2.29). Among 54 957 people with HIV in UnivART, TB disease incidence rates were higher among males than females overall (IRR 1.28, 95% CI 1.18-1.39), among males compared with females on ART (IRR 1.58, 95% CI 1.40-1.77), and among males compared with females not on ART (IRR 1.11, 95% CI 0.99-1.25).
Conclusion: In this medium TB and HIV burden setting, TB disease incidence was higher among males than females with HIV, despite similar prevalence of TB infection.

The first evidence that Orthopoxvirus induced the expansion and the recall of effector innate Vδ2T-cells was described in a macaque model. Although, an engagement of αβ T-cells specific response in patients infected with human monkeypox (Mpox) was demonstrated, little is known about the role of γδ T-cells during Mpox infection. IFN-γ-producing γδ T-cells in the resistance to poxviruses may a key role in inducing a protective type 1 memory immunity.

Introduction: Schistosomiasis, a tropical parasitic disease, affects 779 million people globally, with 85% of cases in Africa. The interplay between schistosomiasis and other sexually transmitted infections (STIs) can exacerbate health burdens, but most attention has focused on interactions with HIV, neglecting coinfections with other STIs. This systematic review and meta-analysis aims to understand the role infections play in STIs within schistosomiasis-endemic populations.

Background: People living with HIV (PLWH) have a higher prevalence of diastolic dysfunction and left ventricular hypertrophy (LVH) in cross-sectional studies. Longitudinal data are lacking, especially from Africa.
Objectives: The aim was to examine: 1) the incidence of diastolic dysfunction in PLWH compared to community controls in Tanzania; 2) the progression of diastolic function and LVH in PLWH after antiretroviral therapy initiation; and 3) traditional, endemic, and HIV-specific risk factors for diastolic function and LVH.

Background: Tuberculosis (TB) is a leading cause of death worldwide with over 90% of reported cases occurring in low- and middle-income countries (LMICs). Pre-treatment loss to follow-up (PTLFU) is a key contributor to TB mortality and infection transmission.
Objectives: We performed a scoping review to map available evidence on interventions to reduce PTLFU in adults with pulmonary TB, identify gaps in existing knowledge, and develop a conceptual framework to guide intervention implementation.
