Article Synopsis
- Black women in the U.S. face higher rates of HIV diagnosis and poorer health outcomes compared to non-Black women, largely due to structural and psychosocial factors affecting their mental health.
- A study with 151 Black women living with HIV assessed the impact of microaggressions, macro discrimination, resilience factors, and mental health outcomes using structural equation modeling.
- Findings revealed that microaggressions and resilience have direct effects on mental health outcomes, while resilience also moderates the relationship between discrimination and PTSD symptoms, indicating that mental health support for Black women with HIV is crucial.
People with HIV on combination antiretroviral therapy (ART) have longer life expectancy and are increasingly experiencing age-related comorbidities. Thus, aging with HIV has become a central issue in clinical care and research, which has been particularly challenging with the intersection of the ongoing coronavirus (COVID)-19 pandemic. Since 2009, the International Workshop on HIV and Aging has served as a multidisciplinary platform to share research findings from cross-disciplinary fields along with community advocates to address critical issues in HIV and aging.

Previous efforts to catalyse this reaction with molecular complexes required the addition of exogenous oxidizing reagents or application of potentials greater than the thermodynamic potential for the oxygen reduction reaction-the cathodic process of a DAFC. We report a stable metal-metal bonded diruthenium complex that spontaneously produces dinitrogen from ammonia under ambient conditions.

Methods: Data from medical records were retrospectively collected for patients who had aortic root replacement using Freestyle bioprostheses between 1999 and 2018 at 6 North-Atlantic centers. Survival status was extracted from national registries and results stratified according to indication for surgery.
