How firearm legislation impacts firearm mortality internationally: A scoping review.

Background: The literature on gun violence is broad and variable, describing multiple legislation types and outcomes in observational studies. Our objective was to document the extent and nature of evidence on the impact of firearm legislation on mortality from firearm violence.

Methods: A scoping review was conducted under PRISMA-ScR guidance.

Postoperative protocols for older adults undergoing emergency surgery: a scoping review.

Background: As the population of older adults expands, it is becoming increasingly crucial to develop perioperative protocols to meet their physiologic, functional, and cognitive demands after emergency surgery. We sought to identify protocols that improve the disposition, length of stay, and overall health outcomes of older adults undergoing emergency intracavitary, noncardiac surgery.

Methods: Embase, Cochrane, and MEDLINE databases were searched, and results were deduplicated and uploaded to Covidence.

Retention of hemostatic and immunological properties of frozen plasma and COVID-19 convalescent apheresis fresh-frozen plasma produced and freeze-dried in Canada.

Background: Randomized clinical trial data show that early plasma transfusion may save lives among trauma patients. Supplying plasma in remote environments is logistically challenging. Freeze-dried plasma (FDP) offers a possible solution.
