Resident Physician Duty-hour Requirements: What Does the Public Think?

Introduction: To date, no study has reported on the public's opinion of orthopaedic resident duty-hour requirements (DHR).

Methods: A survey was administered to people in orthopaedic waiting rooms and at three senior centers. Responses were analyzed to evaluate seven domains: knowledge of duty hours; opinions about duty hours; attitudes regarding shift work; patient safety concerns; and the effects of DHRs on continuity of care, on resident training, and on resident professionalism.

CT of suspected thoracic acute aortic injury in the emergency department: is routine abdominopelvic imaging worth the additional collective radiation dose?

This study aimed to determine the incidence of non-traumatic acute aortic injury (AAI) extending from the chest into the abdomen or pelvis in emergency department (ED) patients with acute aortic syndrome (AAS), to estimate the effective dose of the abdominopelvic portion of these CT exams, and to compare the number needed to screen (NNS) with the collective population radiation dose of imaging those stations. All patients (n = 238) presenting to the ED with AAS between March 2014 and June 2015 who were imaged per CT AAI protocol (noncontrast and contrast-enhanced CT angiography of the chest, abdomen, and pelvis) were retrospectively identified in this IRB-approved HIPAA-compliant study. The Stanford classification for positive cases of AAI was further subclassified based on chest, abdominal, or pelvic involvement.

Cerebrospinal fluid sodium rhythms.

Background: Cerebrospinal fluid (CSF) sodium levels have been reported to rise during episodic migraine. Since migraine frequently starts in early morning or late afternoon, we hypothesized that natural sodium chronobiology may predispose susceptible persons when extracellular CSF sodium increases. Since no mammalian brain sodium rhythms are known, we designed a study of healthy humans to test if cation rhythms exist in CSF.
