Is staple line oversewing in patients on chronic anticoagulation during laparoscopic sleeve gastrectomy necessary? Propensity score matching analysis using the 2015-2018 MBSAQIP.

Background: There is an increased incidence of post-operative bleeding in patients on chronic anticoagulation (CAC). This incited some surgeons to oversew the sleeve staple line as a potentially preventive measure for post-operative bleeding. However, there is no clear evidence to assess the effectiveness of staple line oversewing during laparoscopic sleeve gastrectomy (LSG) in patients with CAC.

Mitochondrial dysfunction in peripheral blood mononuclear cells in pediatric septic shock.

Objectives: Mitochondrial dysfunction in peripheral blood mononuclear cells has been linked to immune dysregulation and organ failure in adult sepsis, but pediatric data are limited. We hypothesized that pediatric septic shock patients exhibit mitochondrial dysfunction within peripheral blood mononuclear cells which in turn correlates with global organ injury.

Design: Prospective observational study.

Increased platelet storage time is associated with mitochondrial dysfunction and impaired platelet function.

Background: Hemorrhagic shock is a leading cause of death following severe trauma, and platelet transfusions are frequently necessary to achieve hemostasis. Platelets, however, require special storage conditions, and storage time has been associated with loss of platelet quality. We hypothesized that standard storage conditions have a deleterious effect on platelet mitochondrial function and platelet activation.
