Importance  Ventilator-induced lung injury may arise from heterogeneous lung microanatomy, whereby some alveoli remain collapsed throughout the breath cycle while their more compliant or surfactant-replete neighbors become overdistended, and this is called dynamic alveolar heterogeneity.

Objective  To determine how dynamic alveolar heterogeneity is influenced by ...

Bariatric surgery is the most effective treatment of morbid obesity with a proven survival benefit.1,2 To view bariatric surgery as simply a weight loss procedure is misguided and can lead to inappropriate expectations and potentially dangerous consequences.

Steven M. Frank, MD; Aslam Ejaz, MD, MPH; Timothy M. Pawlik, MD, MPH, PhD

Among patients with known coronary artery disease (CAD), the ideal transfusion trigger based on nadir hemoglobin is still unclear. Three of the largest randomized clinical trials on transfusion triggers and perioperative outcomes were performed among cardiac patients undergoing cardiac surgery,13 a clinical scenario that is ...

This study hypothesizes that surgery cancellations are more frequent in the first 6 months following the placement of a drug-eluting stent and that a higher proportion of early cancellations are associated with acute myocardial infarction or death.

To the Editor Whereas classic teaching highlights reduced infection risk, fewer hospitalizations, and lower total costs associated with hemodialysis (HD) that is initiated via arteriovenous fistula (AVF) vs hemodialysis catheter (HC), and whereas the National Kidney Foundation–Kidney Disease Outcomes Quality Initiative1 first published practice guidelines regarding permanent ...

Importance  Although rare, the incidence of venous thromboembolism (VTE) in pediatric trauma patients is increasing, and the consequences of VTE in children are significant. Studies have demonstrated increasing VTE risk in older pediatric trauma patients and improved VTE rates with institutional interventions. While national evidence-based guidelines for ...

Invited Commentary 
Matthew J. Martin, MD

To say that we are “operating in the dark” when it comes to venous thromboembolism (VTE) screening and prophylaxis in children is an understatement. In this issue of JAMA Surgery, Connelly and colleagues1 have published a technically well-done statistical analysis of the National Trauma Data Bank ...

In characterizing the effect of a 2009 mandate to reduce medical evacuation times in Afghanistan, in this issue of JAMA Surgery, Kotwal and colleages1 demonstrate the effectiveness of combining advanced trauma care capability with informed policy. Unlike any report before it, this study demonstrates that one ...

Invited Commentary

To the Editor Despite the statistics systematically summarized by Hempel and collegues1 in a recent issue of JAMA Surgery, never events (ie, serious, preventable surgical events) have enormously emotional aspects that touch everyone involved. Out of an unlimited number of possible surgical complications, never events carry ...
