Background: Reducing perinatal HIV transmission and optimizing maternal and child health (MCH) outcomes in high HIV prevalence settings is an urgent, but complex, priority. Extant interventions over-emphasize individual-level provider and patient behaviors, and neglect critical health systems-level changes. The 'Integrated Management Team to Improve Maternal-Child Outcomes (IMPROVE)' study implemented a three-part, patient-centered, health-systems-level intervention to improve MCH and HIV outcomes in Lesotho.

Body size is key to many life-history processes, including reproduction. Across species, climate change and other stressors have caused reductions in the body size to which animals can grow, called asymptotic size, with consequences for demography. A reduction in mean asymptotic length was documented for critically endangered North Atlantic right whales, in parallel with declines in health and vital rates resulting from human activities and environmental changes.

Chronic pain is prevalent and often under-addressed among people with HIV and people who use drugs, likely compounding the stress of discrimination in healthcare, and self-medicating along with its associated overdose risk or other problematic coping. Due to challenges in treating pain and HIV in the context of substance use, collaborative, patient-centered patient-provider engagement (PCE) may be particularly important for mitigating the impact of pain on illicit drug use and promoting sustained recovery. We examined whether PCE with primary care provider (PCE-PCP) mediated the effects of pain, discrimination, and denial of prescription pain medication on later substance use for pain among a sample of 331 predominately African Americans with HIV and a drug use history in Baltimore, Maryland, USA.

Vulnerable persons living with HIV (PLWH) are at high risk of cognitive impairment and challenges accessing quality social support in later life. Impaired verbal fluency (VF), a cognitive domain linked to HIV, could impede social support associated with health and well-being for already vulnerable PLWH. We examined the structure of social support, using latent class analysis, and the associations among quantity, specific forms and quality of social support and VF among PLWH.
