DATA COLLECTION PROJECT FOR WEIGHT LOSS SURGERY PROTOCOL# 1103-029, PI Michel Gagner, Co-investigator Data collection is performed on all consenting bariatric patients. In addition to basic demographics, past surgical history, medical and social history, current medications and basic information from physical examination, consultation data, body composition, and quality of life information are collected. Surgery data will include: surgeon’s name, date of operation, operation performed, other procedures performed during the operation, complications that might occur during the operation, operative time, type of bowel reattachment, intestinal limb length, estimated blood loss, amount of blood transfused, specialized instruments used, wound closure, and reason for conversion. After surgery information on length of hospital stay, post-operative complications, weight loss, physical exam, status of previous medical illnesses, symptom assessment, additional medications, additional procedures, re-admissions, re-operations, tissue obtained at operation, and any deaths. THE EFFECTS OF WEIGHT LOSS PRIOR TO SURGERY ON THE COMPLICATIONS OF BARIATRIC PROCEDURES PROTOCOL #1103-030, PI Gladys Strain, Co-investigator Enrollment for this protocol is closed. Data on complications for the final 2 patients will be available when they reach a time point of 6 months after surgery. Patients had participated in a program of nutritional intervention and the encouragement of healthy lifestyle behaviors to prevent weight gain and promote weight loss prior to bariatric surgery. A similar group of patients were followed who did not participate in the program but had weight loss surgery. A statistical analysis of the possible effect on length of hospital stay and complications for six months after surgery will be completed. BARIATRIC SURGERY AND ITS EFFECTS ON ONE METABOLISM -- PROTOCOL #0804-463, PI Sinha and Gladys Strain Recruitment for this protocol is beginning in clinic on Oct 18th. Few studies looking at the effects of bariatric surgery on bone metabolism are available and none have been conducted to compare procedures. Patients eligible for bariatric procedures may participate in studies of bone turnover and density with the support of the General Clinical Research Center at Cornell. Participating subjects will have an assessment of their calcium intake prior to surgery and be followed in regard to their prescribed supplement use after surgery. Markers of vitamin D status and bone metabolism will be studied in the blood and urine and measures of bone density will be followed for a year after surgery. NIH/NIDDK DK66667-01 10/01/03-08/31/08 PI Dr . Paul Berk Co-Investigator Bariatric Surgery Clinical Research Consortium (BSCRC) Longtitudinal Assessment of Bariatric Surgery (LABS) National Institute of Diabetes and Digestive and Kidney (NIDDK) This grant supports the infrastructure and certain patient-related research costs for a Bariatric Surgery Clinical Research Center, one ofsix participating Centers within NIDDKs Longitudal Assessment of Bariatric Surgery consortium (LABS). PATIENTS FOLLOWING GASTRIC BYPASS SURGERY # JFN-0385-0404, Rockefeller University, PI Friedman Co-investigator We are recruiting patients to be followed at Rockefeller University during the weight loss process. Metabolic evaluations and genetic studies will be done in hospital and ambulatory as out patients prior to and following gastric bypass surgery for a 15 month duration after surgery. These studies include fat biopsy, metyrapone testing, hunger evaluations, immunology testing, and studies at St. Lukes’ Obesity Research Center for body composition and resting energy expenditure.
