Spaced education improves the feedback that surgical residents give to medical students: a randomized trial.

Background: Surgery residents teach medical students; feedback is one critical teaching skill. We investigated whether feedback given by surgery residents to students could be improved through an online spaced education program.

Methods: Surgery residents were randomized to receive either a weekly spaced education e-mail during a 9-month period containing teaching bullets on how to provide effective feedback, or no intervention.

Gene expression profiling of malignant mesothelioma.

Purpose: Malignant mesothelioma is a uniformly fatal cancer of the pleural and peritoneal spaces. Several challenging clinical problems include poor understanding of the pathophysiology, inaccurate diagnosis from tissue samples, and unsuccessful treatment strategies. The purpose of this study was to use microarray analysis to identify specific gene expression changes in mesothelioma compared with normal mesothelium.
