Eating expectancies before bariatric surgery: assessment and associations with weight loss trajectories
While presurgical eating behaviors have demonstrated limited prognostic value, cognitions regarding the effects of eating may serve as important predictors of weight loss outcomes after bariatric surgery. The Eating Expectancies Inventory (EEI) is a commonly used, self-report measure of expected consequences of eating; however, its psychometric and predictive properties have not yet been evaluated among bariatric surgery patients.PNPLA3 p.I148M variant is associated with greater reduction of liver fat content after bariatric surgery
Obesity is the major trigger of nonalcoholic fatty liver disease (NAFLD). NAFLD is further favored by the patatin-like phospholipase domain-containing 3 (PNPLA3) p.I148M, transmembrane 6 superfamily member 2 (TM6SF2) p.E167K, and membrane-bound O-acyltransferase domain containing 7 (MBOAT7) rs641738 variants.Gastric bypass for severe obesity: Approaches and outcomes
Bariatric surgery has experienced unprecedented growth in the United States during the last 10 years [1]. Compared with the late 1980s and early 1990s, when approximately 15,000 bariatric operations were performed each year, in 2003 more than 100,000 bariatric operations were performed in the United States. This growth in bariatric surgery, the fastest-growing major operation in the United States, can be explained by 3 factors: (1) the 4-decades-old epidemic of obesity, (2) steadily improving outcomes for several bariatric operations, and (3) the introduction of laparoscopic bariatric surgery with improved perioperative outcomes.
