Background: Transgender women (TGW) and men who have sex with men (MSM) in sub-Saharan Africa have high HIV acquisition risks and can benefit from daily pre-exposure prophylaxis (PrEP). We assessed PrEP adherence by measuring tenofovir-diphosphate (TFV-DP) levels and explore motives for PrEP persistence in TGW and MSM.
Methods: Participants were enrolled in a one-year PrEP programme and made quarterly visits irrespective of whether they were still using PrEP. At their month 6 visit, participants provided a dried blood spot to test for TFV-DP levels; protective levels were defined as those compatible with ≥4 pills per week (700-1249 fmol/punch). Before TFV-DP levels were available, a sub-set of these participants were invited for an in-depth interview (IDI). Semi-structured IDI topic guides were used to explore motives to uptake, adhere to, and discontinue PrEP. IDI data were analyzed thematically.
Results: Fifty-three participants (42 MSM and 11 TGW) were enrolled. At month 6, 11 (20.7%) participants (8 MSM and 3 TGW) were lost to follow up or stopped taking PrEP. Any TFV-DP was detected in 62.5% (5/8) of TGW vs. 14.7% of MSM (5/34, p = 0.01). Protective levels were detected in 37.5% of TGW (3/8), but not in any MSM. Nineteen IDI were conducted with 7 TGW and 9 MSM on PrEP, and 1 TGW and 2 MSM off PrEP. Unplanned or frequent risky sexual risk behaviour were the main motives for PrEP uptake. Among participants on PrEP, TGW had a more complete understanding of the benefits of PrEP. Inconsistent PrEP use was attributed to situational factors. Motives to discontinue PrEP included negative reactions from partners and stigmatizing healthcare services.
Conclusion: While MSM evinced greater adherence challenges in this PrEP programme, almost 40% of TGW were protected by PrEP. Given high HIV incidences in TGW these findings hold promise for TGW PrEP programming in the region.

Transgender women and sex workers in Brazil underutilise HIV prevention services. Understanding preferences and decision-making regarding HIV prevention can help develop new programmes to meet their needs. We conducted semi-structured interviews with 26 transgender women and travesti sex workers in São Paulo, Brazil.

Accurate point-of-care tools are needed to detect early nonadherence to daily HIV regimens and support timely transitions to long-acting options. Emerging evidence suggests that females may require higher adherence than males to achieve equivalent protection. Our next-generation urine tenofovir assay showed high accuracy across sexes but lower urine drug levels among female participants.

Objective: Antimicrobial resistant infections are expected to increase the rate of antibiotic treatment failure in patients during a mass casualty incident. We aim to examine the potential impact of rising antimicrobial resistance (AMR) on medical preparedness and response to a nuclear detonation in the United States (U.S.

Despite growing recognition of the interdependencies of resilience across systems, sectors, and levels (SSLs), translating this understanding into coordinated action remains a challenge. This study identifies seven systemic gaps that reinforce a persistent know–do gap, creating an unhealthy that reinforces fragmentation across SSLs. In response, seven prerequisites for synergizing resilience are proposed, along with a working definition of Synergistic Resilience.

Objectives: Computer-aided detection (CADe) systems improve adenoma detection during colonoscopy, but the influence of bowel preparation quality on CADe performance is unclear. This study assessed whether different levels of adequate bowel preparation affect CADe effectiveness.
Methods: A post-hoc pooled analysis was conducted using individual patient data from three randomized controlled trials comparing CADe-assisted colonoscopy to standard colonoscopy (SC).
