Effects of Teaching Evidence-Based Medicine on Physician Assistant Students' Critical Appraisal, Self-Efficacy, and Clinical Application: A Randomized Controlled Trial.

Purpose: To use a randomized controlled design to explore the effects of evidence-based medicine (EBM) education on physician assistant (PA) students' EBM knowledge, self-efficacy, and evidence-seeking behavior in a simulated clinical situation and to present a model of EBM competence.

Methods: Sixty-one didactic-year PA students from one Midwestern University (2 sequential cohorts) were randomized to receive the standard PA curriculum plus EBM training (intervention) or the standard PA curriculum only (control). Evidence-based medicine knowledge was measured with a validated Fresno test.

Impact of primary tumor location on outcome of liposarcoma patients, a retrospective cohort study.

Background: Tumor location as a prognostic factor for patients with liposarcoma (LPS) has been studied modestly with varying outcomes. The aim was to establish the impact of tumor location on recurrence and survival of LPS patients.

Methods: A retrospective database of patients treated for LPS until December 2017 was used to assess 5-year local recurrence-free survival (LRFS), distant metastasis-free survival (DMFS) and disease-specific survival (DSS) per tumor location using the Kaplan-Meier method and log-rank test.

Myocardial scar characteristics based on cardiac magnetic resonance imaging is associated with ventricular tachyarrhythmia in patients with ischemic cardiomyopathy.

Objectives: We hypothesized that myocardial scar characterization using cardiac magnetic resonance imaging (CMR) may be associated with the occurrence of ventricular tachyarrhythmia (VT), appropriate implantable cardioverter-defibrillator (ICD) therapy and mortality.

Background: Since a minority of patients with prophylactic ICD implantation receive appropriate ICD therapy, there is a need for more effective risk stratification for primary prevention in patients with ischemic cardiomyopathy.

Methods And Results: In 99 patients with ischemic cardiomyopathy, CMR was performed prior to ICD implantation.

Reliability of radiographic findings and the relation to etiologic agents in community-acquired pneumonia.

In a clinical setting the chest radiograph is the reference standard in establishing the diagnosis of community-acquired pneumonia (CAP). This study aimed to assess interobserver reliability (IR) of radiographic findings and the relationship to different causative pathogens in CAP. Chest radiographs of 192 patients with pneumonia, obtained from a database, were reviewed by 2 radiologists and 1 respiratory physician without specific clinical information.

[Gastrointestinal surgery and gastroenterology. XIV. Mesenteric abnormalities in generalised vascular disease].

Various forms of vasculitis may result in mesenteric ischaemia, ischaemic colitis or aneurysm formation in the aorta or intestinal blood vessels. Vasculitides may involve large- and/or medium-sized vessels, medium- and/or small-sized vessels, or small-sized vessels only. It is essential to differentiate between the different forms of vasculitis since diagnostic tests and therapies differ greatly.
