Global Use, Adaptation, and Sharing of Massive Open Online Courses for Emergency Health on the OpenWHO Platform: Survey Study.

Background: The COVID-19 pandemic demonstrated the global need for accessible content to rapidly train health care workers during health emergencies. The massive open access online course (MOOC) format is a broadly embraced strategy for widespread dissemination of trainings. Yet, barriers associated with technology access, language, and cultural context limit the use of MOOCs, particularly in lower-resource communities.

Safety of Triple-Dose Rifampin in Tuberculosis Treatment: A Systematic Review and Meta-Analysis.

Background: There is growing interest in using high-dose rifampin for tuberculosis treatment. Recent studies suggest that triple-dose rifampin (TDR; ≥30 mg/kg/day) may be unsafe. We updated a systematic review to investigate the safety and efficacy of TDR.

Tissue histology and depuration of per- and polyfluoroalkyl substances (PFAS) from dairy cattle with lifetime exposures to PFAS-contaminated drinking water and feed.

Plasma, milk and tissue samples were collected from 30 dairy cattle (0.4 to 8.9 years of age) with lifetime exposures to perfluoroalkyl substances (PFAS) removed from a PFAS-contaminated farm and provided PFAS-free feed and water.

Drug Development.

Background: We have previously reported the neuroprotective effects of fosgonimeton in amyloid-β (Aβ)-driven preclinical models of Alzheimer's disease (AD). Fosgonimeton is an investigational small-molecule positive modulator of the neurotrophic hepatocyte growth factor (HGF) system, currently under investigation for mild-to-moderate AD (LIFT-AD; NCT04488419). Given the recent approvals of Aβ-targeting monoclonal antibodies (Aβ-mAbs) for the treatment of AD, and growing recognition that combination therapies may improve treatment outcomes, we sought to investigate the preclinical activity of fosgonimeton in the presence of Aβ-mAbs.

Drug Development.

Background: Accumulating evidence highlights impairment of autophagy as a key pathological feature of neurodegenerative diseases including Alzheimer's disease (AD). Autophagy is a highly dynamic, lysosome-based degradation process that promotes the clearance of degenerative factors to maintain cellular functions, preserve metabolic integrity, and ensure survival. Impaired autophagic function leads to the abnormal accumulation of autophagic vesicles (i.
