Who Serves Where: A Geospatial Analysis of Access to Endocrine Surgeons in the United States and Puerto Rico.

BACKGROUND: The association between surgical volume and patient outcome is well established, with higher case volume associated with a lower risk of complications. We hypothesized that the geographic distribution of endocrine/head and neck surgeons with an endocrine focus in the United States and Puerto Rico may limit access to many potential patients, particularly in rural areas. METHODS: We used web-based directories from the American Association of Endocrine Surgeons, American Head and Neck Society, and the American Academy of Otolaryngology-Head and Neck Surgery to identify endocrine surgery specialists in the United States and Puerto Rico. Using geographic coordinates and OpenStreetMap and Valhalla software, we calculated the areas within a 60-, 90-, or 120-minute driving distance from specialist offices. We used 2020 U.S. Census Data to calculate census tract populations inside or outside the accessible areas. RESULTS: Excluding duplicate providers across organizations, we geocoded 603 specialist addresses in the United States and Puerto. We found that 23.76% (78.3 million) of Americans do not have access to a society-affiliated endocrine/head and neck surgeon with an endocrine focus within a 60-minute drive, 14.37% (47.4 million) within a 90-minute drive, and 8.38% (27.6 million) within a 120-minute drive. We observed that the areas of coverage are primarily focused on metropolitan areas. CONCLUSION: Nearly one-third of Americans do not have access to a society-affiliated endocrine/head and neck surgeon with an endocrine focus within a 1-hour drive, highlighting a concerning geographic barrier to care. Further work is needed to facilitate patient access and mitigate disparities in quality care.

Magnetic Compression Anastomosis (Magnamosis) for Functional Undiversion of Ileostomy in Pediatric Patients.

INTRODUCTION: Magnamosis forms a compression anastomosis using self-aligning magnetic Harrison rings. The device has been approved by the Food and Drug Administration for first-in-human testing and has been applied in adults for intestinal anastomosis during urologic reconstructions. We now report the first cases of magnamosis to functionally undivert the fecal stream from a previously created loop ileostomy in pediatric patients. MATERIALS AND METHODS: Case 1: A 4-year-old male underwent a diverting loop ileostomy for malignant bowel obstruction. The obstruction gradually resolved with chemotherapy, and persistently high stomal output and malnutrition prompted undiversion. Case 2: A 16-year-old female with iloecolonic polyposis underwent ileoproctectomy with J pouch and diverting ileostomy. The magnamosis functional undiversion (FUN) technique involves introducing a Harrison ring through each stomal limb under general anesthesia with X-ray guidance. Magnets are each tied with sutures that exit the stoma and are then tied to each other externally. The device is removed when patency is detected. RESULTS: The introduction procedure took less than 20 minutes and there were no complications. Enteral feeding was initiated 24 and 6 hours postoperatively, and distal passage of stool occurred by the fourth and fifth days, respectively. Magnets were removed 14 and 15 days postoperatively, without evidence of leak. CONCLUSION: We conclude that the magnamosis undiversion procedure is a safe, minimally invasive way to gradually refunctionalize the excluded distal bowel after previous diverting ostomy.

Cardiovascular risk surveillance to develop a nationwide health promotion strategy: the grenada heart project.

OBJECTIVE: The Grenada Heart Project aims to study the clinical, biological, and psychosocial determinants of the cardiovascular health in Grenada in order to develop and implement a nationwide cardiovascular health promotion program. METHODS: We recruited 2,827 adults randomly selected from the national electronic voter list. The main outcome measures were self-reported cardiovascular disease and behavioral risk factors, anthropometric measures, blood pressure, point-of-care testing for glucose and lipids, and ankle-brachial index. Risk factors were also compared with the U.S. National Health and Nutritional Survey data. RESULTS: Prevalence of cardiovascular disease risk factors were: overweight and obesity-57.7% of the population, physical inactivity-23.4%, diabetes-13.3%, hypertension-29.7%, hypercholesterolemia-8.6%, and smoking-7%. Subjects who were physically active had a significantly lower 10-year Framingham risk score (p<0.001). Compared with the U.S. National Health and Nutrition Survey data, Grenadian women had higher rates of adiposity, diabetes, hypertension, and elevated low-density lipoprotein cholesterol, whereas Grenadian men had a higher rate of diabetes, a similar rate of hypertension, and lower rates of the other risk factors. Prevalence of peripheral arterial disease was 7.6%; stroke and coronary heart disease were equally prevalent at ∼2%. CONCLUSIONS: This randomly selected adult sample in Grenada reveals prevalence rates of obesity, hypertension, and diabetes significantly exceeding those seen in the United States. The contrasting, paradoxically low levels of prevalent cardiovascular disease support the concept that Grenada is experiencing an obesity-related "risk transition." These data form the basis for the implementation of a pilot intervention program based on the Institute of Medicine recommendations and may serve as a model for other low- and middle-income countries.
