Initial report on special operations clinical training at a civilian academic medical center.

Background: Military-civilian partnerships for combat casualty care skills training have mostly focused on traditional, combat surgical team training. We sought to better understand US Special Forces (SF) Medics' training at West Virginia University in Morgantown, West Virginia, a Level 1 trauma center, via assessments of medical knowledge, clinical skills confidence, and technical performance.

Methods: Special Forces Medics were evaluated using posttraining medical knowledge tests, procedural skills confidence surveys (using a 5-point Likert scale), and technical skills assessments using fresh perfused cadavers in a simulated combat casualty care environment.

Variations in mortality in Medicare recipients on extracorporeal membrane oxygenation.

Background: Extracorporeal membrane oxygenation (ECMO) is a rescue modality against severe cardiac and pulmonary compromise. We sought to assess variation in mortality and associated environmental and infrastructural predictors among Medicare beneficiaries on ECMO.

Methods: We used Medicare claims data to evaluate hospitalizations between 2017 and 2019 during which beneficiaries required ECMO.

Common Tenets in Repair of Primary Paraesophageal Hernias: Reducing Tension and Maximizing Length.

Tension-free repair remains the most important principle of surgical management of giant paraesophageal hernias. The axial tension is relieved by generous circumferential mobilization of the esophagus in the mediastinum to the level of subcarina. An esophageal lengthening procedure may be necessary for a true short esophagus.
