INTRODUCTION While teaching patient safety and quality improvement (QI) skills to medical students is endorsed as being important, best practice for achieving learner outcomes in QI is particularly unclear. We systematically reviewed QI curricula for medical students to identify approaches to QI training that are associated with positive learner…[Read more]

The classic Braak neuropathologic staging model in Parkinson disease (PD) suggests that brain lesions progress from the medulla oblongata to the cortex. An alternative model in which neurodegeneration first occurs in the cortex has also been proposed. These 2 models may correspond to different patient phenotypes. To test these 2 models and to…[Read more]

PURPOSE Structure-guided total variation is a recently introduced prior that allows reconstruction of images using knowledge of the location and orientation of edges in a reference image. In this work, we demonstrate the advantages of a variant of structure-guided total variation known as directional total variation (DTV), over traditional total…[Read more]
