Metabolic Health Immersion for Medical Education: A Pilot Program with Continuous Glucose Monitors in Medical and Dental Students.

Diet-related chronic diseases are increasing in prevalence and poised to dominate the future careers of current medical students. While the value of nutritionally-informed care and nutrition-based health interventions is increasingly recognized, nutrition education is inconsistently and often inadequately included in medical school curricula. One obstacle to incorporating nutrition into medical and dental school curricula is the density of existing coursework, with incorporation of new material necessitating removal of other material. One solution is to engage students outside the classroom in immersive education in nutrition and metabolism using health-wearables. We report the Metabolic Health Immersion for Medical Education pilot program, spearheaded and designed by Harvard Medical students centering on use of continuous glucose monitors (CGM). Students reported enjoyment with the study, felt encouraged to improve health behaviors, and shared that the experience enhanced their understanding of nutrition and metabolism, was valuable to their medical education, and would influence their future patient care. This study demonstrates proof-of-principle that metabolic health immersion opportunities for health care trainees provide a means of helping to address the current deficit in medical school nutrition education.

Effect of adjustable gastric banding on changes in gastroesophageal reflux disease (GERD) and quality of life.

OBJECTIVE: Bariatric surgery is an effective treatment for the reduction of weight in obese patients (BMI ≥ 40 kg/m(2) or 30 kg/m(2) with ≥1 comorbidities), who are refractory to behavioral and medical therapies. This study examined the effect of the adjustable gastric band (AGB) system on changes in gastroesophageal reflux disease (GERD) and patient-reported outcomes, including measures of quality of life. METHODS: Two-year interim analysis of patients (N = 171) in the 5 year, prospective APEX study who reported GERD prior to the AGB procedure. An unrecorded number of hiatal hernia repairs were conducted during the APEX study. RESULTS: At baseline, 171 of 395 patients (43%) reported GERD requiring daily medical therapy. After 2 years, 122 patients had sufficient data to assess outcome (71%). Complete resolution of GERD was reported in 98 patients (80%), improvement in 13 (11%), no change in 9 (7%), and worsening in 2 (2%). Overall, 91% of GERD patients experienced resolution and/or improvement of GERD. Baseline BMI was not significantly different among the GERD response categories (resolved, improved, and stable/worse), p = 0.4581. Mean ΔBMI and percentage excess weight loss (%EWL) were: -8.8 kg/m(2)/-0.9%, -11.4 kg/m(2)/-53.9%, -6.4 kg/m(2)/-36.1%, and -7.1 kg/m(2)/-31.2%, respectively. There were no significant differences in reductions in BMI or %EWL between responder groups (resolved versus stable/worse ΔBMI p = 0.1031, %EWL p = 0.0667 OR resolved/improved versus stable/worse ΔBMI p = 0.0918, %EWL p = 0.0552). After 2 years, resolution or improvement occurred in pre-existing comorbidities: type 2 diabetes (96%), hypertension (91%), hyperlipidemia (77%), obstructive sleep apnea (86%), osteoarthritis (93%), and depression (75%). Patient satisfaction with AGB was assessed as: very satisfied/satisfied (87%), very satisfied (50%), dissatisfied (5.0%). Quality of life measured by the Obesity and Weight-Loss Quality of Life Instrument (GERD patients) significantly improved from baseline. CONCLUSION: Obese patients with GERD had meaningful improvement in patient-reported outcomes with the AGB system. In addition, other obesity-related comorbidities and measures of quality of life improved.

Interim results at 48 weeks of LAP-BAND AP experience (APEX) study: prospective, multicenter, open-label longitudinal patient observational study.

BACKGROUND: The development of laparoscopic adjustable gastric banding marked a breakthrough in minimally invasive bariatric surgery. The unique features of gastric banding, including device adjustability, lack of malabsorption, and easy reversibility, have contributed to its widespread use. Since Food and Drug Administration approval of the first laparoscopic adjustable gastric band, the device design has undergone engineering improvements. The LAP-BAND AP (LBAP) system received Food and Drug Administration approval in 2006. Little is known about the safety and efficacy of this new system. Our objective was to prospectively assess the efficacy and safety of the LBAP system in real-world clinical settings at 50 clinical centers throughout the United States. METHODS: In an open-label 5-year evaluation, 508 severely or morbidly obese patients from 50 centers in the United States underwent surgery using the LBAP system. The present interim report describes the results from 323 patients after ≥ 48 weeks of follow-up. RESULTS: By week 48, the patients had experienced a mean percentage of excess weight loss of 46% and a mean ± standard deviation reduction in the body mass index of 8.4 ± 3.69 kg/m(2). Sixteen patients (3.1%) experienced a severe device- or procedure-related adverse event. There were no deaths. CONCLUSION: These 48-week interim data demonstrate that the LBAP system offers a safe and effective therapy to reduce weight in severely obese patients.

Safety and effectiveness of bariatric surgery: Roux-en-y gastric bypass is superior to gastric banding in the management of morbidly obese patients: a response.

BACKGROUND: The recent article by Guller, Klein, Hagen was reviewed and discussed by the authors of this response to critically analyze the validity of the conclusions, at a time when patients and providers depend on peer reviewed data to guide their health care choices. The authors of this response all have high volume bariatric surgery practices encompassing experience with both gastric bypass and gastric banding, and have made significant contributions to the peer reviewed literature. We examined the assumptions of the paper, reviewed the main articles cited, provided more evidence from articles that were included in the materials and methods of the paper, but not cited, and challenge the conclusion that Roux-en-Y gastric bypass is superior to gastric banding. RESULTS AND DISCUSSION: The paper by Guller et al was subject to significant bias. The authors did not demonstrate an understanding of gastric banding, selectively included data with unfavorable results towards gastric banding, did not provide equal critique to the literature on gastric bypass, and deliberately excluded much of the favorable data on gastric banding. CONCLUSION: The paper's conclusion that gastric bypass is the procedure of choice is biased, unsubstantiated, not supported by the current literature and represents a disservice to the scientific and health care community.

Sporadic aplasia cutis congenita.

Aplasia cutis congenita (ACC) is a rare group of disorders characterized by the focal absence of skin at birth. The majority of cases affect the scalp, but involvement of the trunk and extremities has been described. Proposed etiologies for ACC include infection, vascular malformations, amniogenesis, and teratogens, but no unifying theory has been identified. We present the case of a 1-day-old female with large, bilateral posterolateral trunk skin defects noted at birth. The prenatal history was significant for maternal diabetes, fetal papyraceus at 12 weeks' gestation, and a family history of limb defects. The infant was treated non-surgically with local wound care and antibiotics, as well as frequent dressing changes. The areas of absent skin developed a granulation-tissue layer followed by re-epithelialization and mild wound contracture. With early identification of the etiology of the lesions and appropriate investigation and treatment, including conservative wound management, aplastic lesions can heal successfully without affecting growth, but may require cosmetic repair at a later stage.

Robot-assisted endoscopic intrauterine myelomeningocele repair: a feasibility study.

BACKGROUND: Animal experiments have suggested that the intrauterine environment causes secondary injury to the congenitally dysplastic spinal cord. This in turn suggests that early closure of the myelomeningocele sac might prevent secondary injury and therefore improve neurologic outcome. This study was designed to examine the technical feasibility of performing intrauterine myelomeningocele repair using a robot-assisted endoscopic system in an animal model. METHODS: Six fetal sheep underwent creation and repair of a full-thickness skin lesion using the da Vinci system. RESULTS: With the device's advanced articulated instruments and three-dimensional optics, it was possible to endoscopically repair the induced skin defects. CONCLUSION: We conclude that, with the recent evolution in robotics and minimally invasive techniques, intrauterine endoscopic surgery has become a realistic goal that promises to reduce the associated risks of fetal surgery and extend the indications for its use.
