Sex-specific associations between cerebrospinal fluid inflammatory biomarkers and cognition in antiretroviral-naïve people with HIV in rural Uganda.

Globally, people with HIV (PWH) experience a broad spectrum of cognitive impairment that can be noted both before and after initiation of antiretroviral therapy (ART). Sex differences in immune function have been implicated in differential cognitive outcomes. Here, we report sex differences in cerebrospinal fluid (CSF) markers in relation to cognitive performance in a subset of ART-naïve PWH participating in the Rakai Neurology Cohort Study.

Community client-led anti-retroviral therapy delivery for people newly diagnosed with HIV: a pilot study in Nakivale Refugee Settlement in Uganda.

Engaging in HIV care services can be challenging for refugees as they navigate new care systems while meeting daily needs. This pilot study assessed Early Community Client-led ART Delivery (Early CCLAD) as a differentiated care strategy for those newly diagnosed with HIV in Nakivale Refugee Settlement, Uganda. Early CCLAD was a community antiretroviral therapy delivery option where group members take turns coming to the health center.

Advancing poliovirus eradication: lessons learned from piloting direct molecular detection of polioviruses in high-risk and priority geographies.

Unlabelled: In the Global Polio Laboratory Network (GPLN), poliovirus (PV) screening results from acute flaccid paralysis (AFP) surveillance is based on virus isolation (VI) through cell culture, entailing long turnaround times and the amplification of live poliovirus. An alternative Direct Detection strategy (DD-ITD) for screening viral nucleic acid from stools, bypassing the need for virus culture, has been developed and extensively validated by GPLN partners. A multi-laboratory demonstration project was conceived to field-test the DD-ITD method by GPLN laboratories from the WHO African, Western Pacific, and Eastern Mediterranean regions, where wild serotype 1 or vaccine-derived polioviruses still circulate.
