Background: This systematic review evaluated the reliability of ChatGPT as a supportive tool in anatomy education and its performance across various anatomical topics. Following PRISMA guidelines, English-language studies published between 2023 and 2025 were included. Searches were conducted in Google Scholar, PubMed, Springer, and Scopus using the keywords "ChatGPT," "anatomy," and "education."

Results: After removing duplicates and screening titles and abstracts, 26 full-text articles were reviewed. Quality assessment using Joanna Briggs Institute criteria rated 22 articles as moderate quality, 1 as high quality, and 3 as low quality; low-quality studies were excluded, leaving 23 articles for analysis. Accuracy rates ranged from 75.2% to 98.6% for ChatGPT-4o, 4.0% to 97.3% for ChatGPT-4, 28.0% to 72.0% for ChatGPT-3.5, and 34.2% to 67.2% for unspecified models. ChatGPT-3.5 Turbo showed 38.4% accuracy in one study, and ChatGPT-4o Mini, 89.2%. Gross anatomy was the most addressed topic (29.0%), followed by thoracic (9.7%), abdominal, upper extremity, and musculoskeletal anatomy (6.5%). ChatGPT-3.5 was the most used model (46.4%), followed by ChatGPT-4 (29.6%), ChatGPT-4o (7.1%), and ChatGPT-4o Mini (7.1%).

Conclusion: ChatGPT has potential as a complementary tool in anatomy education, yet careful evaluation and further evidence-based research are needed to improve its reliability and effectiveness.

Background: Physician residency imposes substantial physical and emotional demands, with the second postgraduate year (PGY-2) being particularly challenging due to increased responsibilities and overnight call. This prospective pilot study examined changes in cardiorespiratory fitness (CRF), body composition, and depressive symptoms across PGY-2 in orthopedic surgery and physical medicine and rehabilitation residents.

Methods: PGY-2 residents at a single academic medical center were assessed pre-, mid-, and post-PGY-2. CRF was measured using treadmill cardiopulmonary exercise testing, body composition via seven-site skinfold measurements, depressive symptoms using the Patient Health Questionnaire-9 (PHQ-9), and self-reported physical activity via the International Physical Activity Questionnaire.

Results: Six residents enrolled (67% male, median age 31 years); four completed all assessments. Physical activity declined from high pre-PGY-2 to moderate mid-PGY-2. Median body fat increased mid-PGY-2 (16.5% to 17.6%) and returned toward baseline post-PGY-2 (16.5%). PHQ-9 scores remained low overall, with a transient mid-year increase driven by fatigue/low energy. Peak CRF showed modest, transient mid-year reductions.

Conclusion: PGY-2 was associated with reduced physical activity and transient changes in physical and mental health. These exploratory findings suggest that PGY-2 may represent a window for targeted wellness interventions and support future larger, adequately powered, longitudinal studies.

Introduction: This study aimed to identify patient and clinical characteristics associated with an operative time of >2 hours for patients undergoing laparoscopic hysterectomy for benign indications.

Methods: A retrospective cohort study design was employed to examine which patient and clinical characteristics were associated with longer operative times. A bivariate analysis was conducted comparing patients who underwent laparoscopic hysterectomy with operative times of ≤2 hours versus those with times >2 hours, followed by multivariate logistic regression to identify characteristics independently associated with an operative time of >2 hours.

Results: A total of 82 and 37 patients who underwent laparoscopic hysterectomy had operative times of ≤2 or >2 hours, respectively. Multivariate logistic regression revealed that a one-unit increase in American Society of Anesthesiologists (ASA) physical status classification (adjusted odds ratio [aOR] 2.95; 95% confidence interval [CI] 0.46-5.65; P = 0.02) and history of hypertension (aOR 2.98; 95% CI 1.10-8.02; P = 0.03) were independently associated with an operative time >120 minutes.

Conclusion: ASA physical status classification and history of hypertension were independently associated with increased operative time for laparoscopic hysterectomy.

Both positive and negative feedback play important roles in the personal and professional development of medical trainees. While positive feedback is often considered easier to provide, limited information exists on how to best administer and receive constructive (or "negative") feedback to foster clinical growth. Self-determination theory is a psychological framework that describes how various factors (e.g., relatedness, autonomy, and competency) affect one's intrinsic and extrinsic motivation. We posit that approaching feedback through the lens of self-determination theory, with a particular focus on balancing trainee autonomy with maintaining professional relationships, can provide valuable guidance for enhancing both the delivery and reception of negative feedback in graduate medical education.
