Quality matters: Artificial intelligence-based assessment of feedback quality predicts technical skill improvement.

Introduction: Consistently delivering high-quality feedback is critical, yet challenging, in surgical education. We hypothesized that feedback quality, as assessed by artificial intelligence (AI, Teach1) based-tools, would correlate with improvements in technical skill acquisition during simulated paracentesis training.

Methods: Seventy-five fourth-year medical students meeting inclusion criteria (baseline Objective Structured Assessment of Technical Skills scores ≤20) performed paracentesis on simulators, received instructor feedback via a digital platform, and completed a second attempt.

A new angle on RGS protein modulation.

In most drug discovery efforts targeting regulator of G-protein signaling (RGS) proteins, inhibiting their activity is the end-goal. A recent article by Aryal et al. presents a novel strategy to stabilize RGS2 by blocking its degradation via the ubiquitin-proteasomal system rather than inhibiting its function, a shift from developing small-molecule inhibitors targeting RGS proteins to modulate G-protein-coupled receptor (GPCR) signaling.

Age and Sex Differences in Anterior Cruciate Ligament-Return to Sport after Injury Subscale Scores of Emotion, Risk Appraisal, and Confidence After ACL Reconstruction.

Background: The Anterior Cruciate Ligament-Return to Sport after Injury (ACL-RSI) scale is widely used after anterior cruciate ligament reconstruction (ACLR), but its 3 subscale domains of emotion, risk appraisal, and confidence are rarely considered when assessing readiness to return to sport (RTS). Current guidelines for ACL-RSI scores at time of RTS are derived from adult-only studies, and there is a need for age- and sex-specific data to guide RTS decision-making.

Purpose/hypothesis: The purpose of this study was to investigate differences in ACL-RSI subscale scores by age and sex.
