Teaching for adaptive expertise in biomedical engineering ethics.

This paper considers an approach to teaching ethics in bioengineering based on the How People Learn (HPL) framework. Curricula based on this framework have been effective in mathematics and science instruction from the kindergarten to the college levels. This framework is well suited to teaching bioengineering ethics because it helps learners develop "adaptive expertise". Adaptive expertise refers to the ability to use knowledge and experience in a domain to learn in unanticipated situations. It differs from routine expertise, which requires using knowledge appropriately to solve routine problems. Adaptive expertise is an important educational objective for bioengineers because the regulations and knowledge base in the discipline are likely to change significantly over the course of their careers. This study compares the performance of undergraduate bioengineering students who learned about ethics for stem cell research using the HPL method of instruction to the performance of students who learned following a standard lecture sequence. Both groups learned the factual material equally well, but the HPL group was more prepared to act adaptively when presented with a novel situation.

Outcomes of bariatric surgery in patients > or =65 years.

BACKGROUND: Although the Medicare Coverage Advisory Committee found that significant evidence supports the safety and effectiveness of bariatric surgery, few data are available on the outcomes of bariatric procedures in patients > or =65 years. The aim of this study was to report on contemporary outcomes of Roux-en-Y gastric bypass (RYGB) in patients > or =65 years. METHODS: We reviewed prospectively collected data from all patients > or =65 years who underwent RYGB at two Florida university-based programs from 1999 to 2005. Similarly, the Florida Discharge Database was queried for patients> or =65 years who had undergone RYGB from 1999 to 2005. The data are presented as the mean +/- SEM. RESULTS: A total of 25 patients > or =65 years had undergone RYGB at our institutions (age 68 +/- 1 years, body mass index 50 +/- 3 kg/m(2)). The overall complication rate was 20%, and the length of stay was 7 +/- 3 days. One patient (4%) died 5 weeks postoperatively of septic complications. For the 13 patients with a median follow-up of 21 months (range 9-61), the percentage of excess body weight loss was 51% +/- 7%; medication use for co-morbidities decreased from 9 +/- 1 to 4 +/- 1 medications/day (P <.01). The Florida Discharge Database reported 231 patients > or =65 years who had undergone RYGB. In that group of patients, the mean age was 67 +/- 0.2 years, the length of stay was 6 +/- 1 days, in-hospital mortality rate was 1.3%, and the overall complication rate was 15%. CONCLUSION: In a small cohort of patients > or =65 years, RYGB resulted in significant weight loss and resolution of obesity-related co-morbidities. The findings from the mandatory reported Florida Discharge Database strongly confirmed the safety of RYGB in patients > or =65 years.
