Risk factors for postoperative bleeding in bariatric surgery.

Background: Postoperative bleeding remains a relatively common complication following bariatric surgery and may lead to morbidity and even mortality.

Objective: To develop a prediction model to identify patients at risk for postoperative bleeding.

Setting: Rode Kruis Ziekenhuis, Beverwijk, the Netherlands.

Transvenous vagus nerve stimulation does not modulate the innate immune response during experimental human endotoxemia: a randomized controlled study.

Introduction: Vagus nerve stimulation (VNS) exerts beneficial anti-inflammatory effects in various animal models of inflammation, including collagen-induced arthritis, and is implicated in representing a novel therapy for rheumatoid arthritis. However, evidence of anti-inflammatory effects of VNS in humans is very scarce. Transvenous VNS (tVNS) is a newly developed and less invasive method to stimulate the vagus nerve.

Evaluation of the ICDP-UEMS Dermatopathology Examination.

A detailed analysis of the results of the international annual International Committee for Dermatopathology-Union Européene des Médecins Specialistes dermatopathology examination was undertaken to identify clues for further improvement. The analysis covered 5 consecutive years (2006-2010) and involved a total of 860 questions (591 common questions and 269 uncommon questions) and 181 participants. It focused on the overall performance of the participants, the performance per part of the examination (theoretical or practical), the performance per format of question (multiple choice or open), the performance per dermatopathological topic, and the performance per professional background (dermatologist or pathologist).
