Characteristics of Prader-Willi Syndrome and Early-onset Morbid Obesity
Prader-Willi SyndromeObesityPrader-Willi syndrome (PWS) is a rare genetic disorder that affects about 1 in 14,000 people in the United States. As the most commonly identified genetic cause of obesity, PWS is often confused with Early-onset Morbid Obesity (EMO). Individuals with EMO show some signs of PWS, but clinically do not have PWS. The purpose of this study is to evaluate the clinical features and genetic basis of PWS and EMO, and to determine how these conditions affect a person throughout a lifetime.
Impact of Decision Aids on Bariatric Surgery Choice
ObesityMorbidSleeve gastrectomy, Roux-en-Y gastric bypass, laparoscopic gastric banding, and bioenteric intragastric balloon insertion are common types of bariatric surgeries. These treatment strategies have diverted outcomes in body weight loss, metabolic diseases control, surgical complications, and life quality improvement. Thus, shared decision making (SDM) is necessary to aid patients to choose an appropriate treatment that suits thier needs. Investigators have developed a decision aids (DAs) and plan to conduct a randomized controlled trial (RCT) to evaluate its impact on obese patients. The measurements include a battery of interview-based questionnaires and evaluations of decision regret and knowledge improvement. Investigators expect the DAs would benefit the intervention group in the aspects of knowledge, communication and anxiety status during and after their treatment sessions.
Depressive State After Sleeve Gastrectomy
ObesityMorbid1 moreObesity is an epidemic disease that continues to increase causing morbidity and mortality to those who suffer. Obese patients suffer, frequently, from a depressive state, anger, and emotional disturbances. It cannot be recognized and depression causes obesity affecting eating habits or obesity causes depression based on physical, social and occupational limitations. Many times we see that obese patients are discriminated in every sense of daily life increasing their depressive state. The best treatment for obesity is bariatric surgery that causes a sufficient weight loss to correct sleep apnea, diabetes, hypertension, and many other co-morbidity. The study is based on elucidating the effect of sleeve gastrectomy in obese patients suffering from depression
The Effects of Metreleptin in Congenital Leptin Deficiency
Congenital Leptin Deficiency (Disorder)This study has been designed to 1) provide access to metreleptin to the only two individuals in the US known to have congenital leptin deficiency (CLD) and 2) explore a variety of unanswered questions about leptin physiology in general and metreleptin therapy in CLD specifically. The primary study endpoints include the following measures: body composition, measures of hepatic steatosis, measures of insulin sensitivity, and measures of sleep architecture. Secondary study endpoints include assessment of clock gene expression, body temperature, thyroid function, gonadal function, cognitive function, eating behavior, physical activity, mood, quality of life, and body image.
De Novo Lipogenesis in Severity of NAFLD
Nonalcoholic Fatty Liver DiseaseNonalcoholic Steatohepatitis3 moreNAFLD is the most prevalent liver disease in the U.S., and there is a serious need to understand its progression to the advanced state, nonalcoholic steatohepatitis (NASH). Previous studies has shown that elevated de novo lipogenesis (DNL) is the unique, early event distinguishing patients with NAFLD from equally-obese subjects with low IHTG. The purpose of this study is to directly by measure DNL in human liver tissue and comparing it to liver histological scores from patient biopsies.
CiNPT for Abdominoplasties in Post-bariatric Patients Study
ObesityMorbid25 moreThe overarching goal of this research is to assess whether the post-operative use of closed-incision Negative Pressure Therapy (ciNPT) accelerates healing of surgical wounds, improves surgical outcomes, and reduces the rate of local complications in high-risk, obese, post-bariatric patients undergoing abdominal body-contouring procedures (abdominal panniculectomy or "abdominoplasty") compared to standard wound care. The investigators postulate that ciNPT can cost-effectively improve outcomes and standard of post-surgical care in this specific category of patients. This hypothesis will be tested through a prospective, interventional, case-control, randomized clinical trial.
Transit Bipartition After Sleeve Gastrectomy
ObesityMorbid2 moreRetrospective analysis of 100 morbidly obese patients who underwent a transit bipartition (TB) procedure ("Single Anastomosis Sleeve Ileal bypass") for inadequate weight loss or weight recidivism after a previous sleeve gastrectomy. Data were collected prospectively in strictly pseudonymous form. The primary endpoint of the study is weight loss at 1, 3, 6 and 12 months after TB. A subgroup analysis evaluates the effect of the length of the common channel. Secondary endpoints include impact on obesity related comorbidities (type 2 diabetes, hypertension, sleep apnea, gastroesophageal reflux) as well as safety.
Effectiveness of the Mediterranean Diet on Weight Loss After Endoscopic Bariatric Treatmen
ObesityObesity1 moreAll participants were weighed every week for 24 weeks, wearing light clothes to the nearest 0.1 kg, using a body composition analyzer. Height was determined during the first clinic evaluation using a fixed wall stadiometer to the nearest 0.1 cm, in standing position. Intervention: Participants followed a liquid diet plan during the first week after the endoscopic bariatric procedure (Bioenterics Intragastric Balloon - BIB - or Primary Obesity Surgery Endoluminal - POSE -). Subsequently, subjects were randomly assigned either a Mediterranean-style or a protein diet plan. Energy intake was calculated according to the Spanish Consensus on Bariatric Endoscopy. The hypothesis of this project is to analyze whether the Mediterranean-style diet is more effective compared with the open protein diet plans in weight loss and weight relapse in subjects with obesity who underwent endoscopic bariatric therapies.
Evaluation of Protein Intake and Micronutrient Supplementation After Bariatric Surgery
Protein MalnutritionVitamin Deficiency5 moreObesity is a chronic disease in which accumulation of excess body fat can result in impaired health. In cases of severe obesity, weight loss surgery can be necessary as a treatment. There are different forms of surgery but the common basic principle is to restrict food intake and decrease the absorption of food in the stomach and intestines. As a consequence, there is a higher risk of developing nutrient deficiency after surgery and supplementation of protein, vitamins, and minerals can be necessary. This study evaluates intakes of protein, vitamins, and minerals in patients with weight loss surgery and compares them to recommended intakes. Further, this study looks at the role of age, sex, and socioeconomic status in this context.
Patient Reported Outcomes of a "Tailored" Bilio-Pancreatic Limb Length on Daily Food Choices in...
ObesityMorbid Obesity3 moreBariatric surgery (BS) has a history of new procedures and techniques arising and then disappearing due to problems and complications. The present is no different with new and old procedures changing with the regularity of night following day. One of the important questions today in BS is the length and or need/value of the Biliopancreatic limb bypass (BPLL.) The Sleeve and the Band have "0" bypass, the RNY has a "short" bypass and the Biliopancreatic Diversion type procedures have a "long" (distal) bypass. The Mini-Gastric Bypass Original Technique (MGB-OT) version of the One Anastomosis Bypass (OAGB) includes a "medium" length of bypass, longer than the BPLL of the RNY and shorter than the the "Long" BPL of the BPD procedures. In addition, uniquely, the MGB-OT includes a "Tailored" BPLL. Not all OAGB surgeons use this approach and several have argued in favor of a "Fixed" BPLL of 150 cm. This paper is part of a series of studies of the "Tailored" BPLL specifically in MGB-OT patients. Notably it demonstrates in an online survey that patient reported weight loss and food choices change after MGB-OT and in addition the changes are related to the "Tailored" BPLL
