Quality of dictated feedback associated with SIMPL operative assessments of pediatric surgical trainees.

Background: SIMPL is a workplace-based operative performance assessment tool which allows for dictated feedback (DF). To better understand the value of DF, we sought to characterize the type and quality of DF generated during SIMPL evaluations.

Methods: Thematic analysis of DF from SIMPL assessments between June 2017 and December 2018 at a single pediatric surgery fellowship program was performed.

Surgery Tutor for Computational Assessment of Technical Proficiency in Soft-Tissue Tumor Resection in a Simulated Setting.

Background: In competency-based medical education, progression between milestones requires reliable and valid methods of assessment. Surgery Tutor is an open-source motion tracking platform developed to objectively assess technical proficiency during open soft-tissue tumor resections in a simulated setting. The objective of our study was to provide evidence in support of construct validity of the scores obtained by Surgery Tutor.

The elevation of intraocular pressure is associated with apoptosis and increased immunoreactivity for nitric oxide synthase in rat retina whereas the effectiveness of retina derived relaxing factor is unaffected.

Glaucoma is a progressive ocular disease that stands in the upper rank for the cause of blindness in worldwide. In the present study, we aimed to elucidate the possible disturbances occurred in the layers of retina due to an increase in intraocular pressure (IOP) and to verify the effectiveness of retina derived relaxing factor, i.e.

Validation of a novel intraoperative assessment tool: The Surgical Procedure Feedback Rubric.

Background: The Surgical Procedure Feedback Rubric (SPR) is a tool to document resident intraoperative performance and provide targeted feedback to support learning in a competency-based model of surgical education. It differs from other assessment tools because it defines performance criteria by increasing complexity through the use of behavioral anchors, thus embedding standards of performance within the tool. This study explores aspects of validity of the SPR as an assessment tool.

Binding of acellular, native and cross-linked human hemoglobins to haptoglobin: enhanced distribution and clearance in the rat.

It is well established that hemoglobin resulting from red cell lysis binds to haptoglobin in plasma to form a complex. The increased molecular size precludes its filtration by the kidneys, redirecting it toward hepatocellular entry. Chemically cross-linked hemoglobins are designed to be resistant to renal excretion, even in the absence of haptoglobin.
