BACKGROUND: Our aim was to determine if a surgeon's behaviors can encourage or discourage trainees from speaking up when they witness a surgical mistake. STUDY DESIGN: A randomized clinical trial in which medical students (n = 55) were randomly assigned to an "encouraged" (n = 28) or "discouraged" (n = 27) group. Participants underwent personality tests to assess decision-making styles, and were then trained on basic tasks ("burn" then "cut") on a laparoscopic surgery simulator. After randomization, students assisted at a simulated laparoscopic salpingectomy. The senior surgeon used either an "encourage" script (eg, "Your opinion is important.") or a "discourage" script (eg, "Do what I say. Save questions for next time."). Otherwise, the surgery was conducted identically. Subsequently, a surgical mistake was made by the senior surgeon when he instructed students to cut without burning. Students were considered to have spoken up if they questioned the instruction and did not cut. Potential personality bias was assessed with two validated personality tests before simulation. Data were processed with Mann-Whitney and Fisher exact tests. RESULTS: The students in the encouraged group were significantly more likely to speak up (23 of 28 [82%] vs 8 of 27 [30%]; p < 0.001). There was no statistically significant difference between the two groups in personality traits, student training level (p = 1.0), or sex (p = 0.53). CONCLUSIONS: A discouraging environment decreases the frequency with which trainees speak up when witnessing a surgical error. The senior surgeon plays an important role in improving intraoperative communication between junior and senior clinicians and can enhance patient safety.

Objective: To examine whether peri-adolescent children demonstrate the significant racial/ethnic differences in body fatness relative to BMI and in the prevalence and relationship of body composition to risk factors for type 2 diabetes (T2DM) as in adults. Design and Methods: We examined family history of obesity and T2DM, anthropometry, insulin sensitivity and secretory capacity, lipids, and cytokines (IL-6, CRP, TNF-alpha, and adiponectin) in a cohort of 994 middle school students (47% male, 53%, female; 12% African American, 14% East Asian, 13% South Asian, 9% Caucasian, 44% Hispanic, and 8% other). Results: Fractional body fat content was significantly greater at any BMI among South Asians. There were racial/ethnic specific differences in lipid profiles, insulin secretory capacity, insulin sensitivity, and inflammatory markers corrected for body fatness that are similar to those seen in adults. Family history of T2DM was associated with lower insulin secretory capacity while family history of obesity was more associated with insulin resistance. Conclusion: Children show some of the same racial/ethnic differences in risk factors for adiposity-related co-morbidities as adults. BMI and waist circumference cutoffs to identify children at-risk for adiposity-related co-morbidities should be adjusted by racial/ethnic group as well as other variables such as birthweight and family history.

BACKGROUND: The prevalence of obesity in U.S. has been rising at an alarming rate, particularly among Hispanic, African, and Asian minority groups. This trend is due in part to excessive calorie consumption and sedentary lifestyle. We sought to investigate whether parental origins influence eating behaviors in healthy urban middle school students. METHODS: A multiethnic/racial population of students (N = 182) enrolled in the ROAD (Reduce Obesity and Diabetes) Study, a school-based trial to assess clinical, behavioral, and biochemical risk factors for adiposity and its co-morbidities completed questionnaires regarding parental origins, length of US residency, and food behaviors and preferences. The primary behavioral questionnaire outcome variables were nutrition knowledge, attitude, intention and behavior, which were then related to anthropometric measures of waist circumference, BMI z-scores, and percent body fat. Two-way analysis of variance was used to evaluate the joint effects of number of parents born in the U.S. and ethnicity on food preference and knowledge score. The Tukey-Kramer method was used to compute pairwise comparisons to determine where differences lie. Analysis of covariance (ANCOVA) was used to analyze the joint effects of number of parents born in the US and student ethnicity, along with the interaction term, on each adiposity measure outcome. Pearson correlation coefficients were used to examine the relationships between maternal and paternal length of residency in the US with measures of adiposity, food preference and food knowledge. RESULTS: African Americans had significantly higher BMI, waist circumference and body fat percentage compared to other racial and ethnic groups. Neither ethnicity/race nor parental origins had an impact on nutrition behavior. Mothers' length of US residency positively correlated with students' nutrition knowledge, but not food attitude, intention or behavior. CONCLUSIONS: Adiposity measures in children differ according to ethnicity and race. In contrast, food behaviors in this middle school sample were not influenced by parental origins. Longer maternal US residency benefited offspring in terms of nutrition knowledge only. We suggest that interventions to prevent obesity begin in early childhood.

In 2003, the Maimonides Infants & Children's Hospital received a Title VII Residency Training in Primary Care grant to integrate genetic-specific competencies into postgraduate pediatrics education. As part of that endeavor, mandatory yearly genetics objective structured clinical exams (OSCEs) were instituted for third-year residents. This article reports on the first three years of experience with this innovative educational tool.After an overview of genetic concepts, dysmorphology, and communication styles, residents complete a five-station OSCE and receive feedback from standardized patients and from the faculty who observe them. After this clinical exercise, the residents participate in a small-group debriefing session to share strategies for effective communication and clinical case management and to discuss the ethical issues that arise with these genetic cases.In three years, 60 residents have completed the genetics OSCE program. Evaluation data demonstrate that the program has been effective in both introducing genetic-specific challenges and assessing residents' clinical skills. It has helped trainees self-identify both strengths and further training needs. Pre- and postsurveys among the trainees show increased comfort levels in performing 5 of 12 genetic-related clinical tasks.We conclude that genetics OSCEs are an enriching educational tool. Merely providing trainees and practicing physicians with the latest scientific information is unlikely to prepare them for counseling patients about complex genetic issues. Developing proficiency requires focused practice and effective feedback.This article is part of a theme issue of Academic Medicine on the Title VII health professions training programs.

Pediatric overweight challenges us as health care providers to utilize the best strategies we have available to help prevent and treat this nationwide epidemic. Comprehensive behavioral treatment is an effective approach for promoting weight loss and health benefits in children and is a promising approach for adolescents. Pediatricians can play an important role in curbing the rise of overweight through early detection and monitoring, and by using a variety of comprehensive behavioral treatment strategies to help manage overweight in their patients.
