Predicting Mortality in Trauma Research: Evaluating the Performance of Trauma Scoring Tools in a South African Population.

Background Trauma is a leading cause of death and disability in low-resource settings, yet trauma severity scores are seldom validated in these contexts. There is a pressing need to better characterize and compare trauma scoring tools, especially within research frameworks. This study aimed to evaluate the performance of various trauma scoring tools in predicting in-hospital mortality among trauma patients in South Africa.

A Multicomponent Intervention (POSSIBLE) to Improve Perceived Risk for HIV Among Black Sexual Minority Men: Feasibility and Preliminary Effectiveness Pilot Study.

Background: Increased pre-exposure prophylaxis (PrEP) use is urgently needed to substantially decrease HIV incidence among Black sexual minority men. Low perceived risk for HIV (PRH) is a key unaddressed PrEP barrier for Black sexual minority men. Peers and smartphone apps are popular intervention tools to promote community health behaviors, but few studies have used these together in a multicomponent strategy.

Transportation and equipment needs for emergency medical services development in low- and middle-income countries.

Prehospital emergency medical services play a vital role in reducing mortality and disease burden in low- and middle-income countries. However, the availability of adequate prehospital emergency care remains a significant challenge in many resource-limited communities, with over 91% of the African population lacking access to sufficient emergency medical services. This commentary aims to highlight the critical components of transportation infrastructure and medical supply chain challenges for emergency medical service development and propose potential solutions for future study.

Association of freeze-dried plasma with 24-h mortality among trauma patients at risk for hemorrhage.

Background: Blood products form the cornerstone of contemporary hemorrhage control but are limited resources. Freeze-dried plasma (FDP), which contains coagulation factors, is a promising adjunct in hemostatic resuscitation. We explore the association between FDP alone or in combination with other blood products on 24-h mortality.
