Low-Volume and Early-Career Surgeons Have Higher Risk for Reoperation and Complications Following Anterior Cruciate Ligament Reconstruction.

Purpose: To characterize the population of surgeons performing anterior cruciate ligament reconstructions (ACLRs) in the United States and investigate the relationships between surgeon volume, career duration, and practice setting on surgical outcomes.

Methods: A large nationwide insurance database was queried for patients undergoing primary ACLR. Provider gender, degree type (allopathic vs osteopathic), practice setting (academic vs private as defined by ACGME affiliation), surgeon volume per year, and career duration were obtained.

Exploring the Potential of a Smart Ring to Predict Postoperative Pain Outcomes in Orthopedic Surgery Patients.

Poor pain alleviation remains a problem following orthopedic surgery, leading to prolonged recovery time, increased morbidity, and prolonged opioid use after hospitalization. Wearable device data, collected during postsurgical recovery, may help ameliorate poor pain alleviation because a patient's physiological state during the recovery process may be inferred from sensor data. In this study, we collected smart ring data from 37 inpatients following orthopedic surgery and developed machine learning models to predict if a patient had postsurgical poor pain alleviation.

Adolescent female rats recovered from the activity-based anorexia display blunted hedonic responding.

Objective: As patients with anorexia nervosa tend to "like" palatable tastants less than controls, we set out to model this preclinically by using the taste reactivity test (TRT) to assess hedonic state in rats following weight restoration from a bout of activity-based anorexia (ABA).

Method: Female rats (n = 31) were surgically implanted with an intraoral catheter, which allowed experimenters to assess baseline TRT to six tastants. Following baseline TRT, animals were either exposed to the activity-based anorexia condition (ABA; 1.
