Observational Study
Predictors of noninvasive mechanical ventilation weaning failure in the emergency department.
To analyze factors related to the failure of noninvasive mechanical ventilation (NIV) weaning in a hospital emergency department (ED). ⋯ Weaning failure occurs in 17% of ED patients on NIV. Time on NIV, HCO3 concentration, and a pH less than 7.35 before weaning are independently associated with failure to wean from the respirator.

Observational Study
Characteristics of human immunodeficiency virus exposure and predictors of time until access to postexposure prophylaxis: a prospective observational study.
The efficacy of postexposure prophylaxis (PEP) after human immunodeficiency virus (HIV) contact relies on administering the treatment within 4 hours of contact with the virus. This study aimed to evaluate predictors of the time that elapses between HIV exposure and emergency department arrival. ⋯ Delay in seeking PEP after HIV exposure is greater among individuals exposed during sexual intercourse. Knowledge of the PEP program and prior use of it are associated with less delay. Exposure during sexual intercourse, alcohol and drug use, and chemsex are associated with longer delays, especially in men who have sex with men.
