Self-Harm Before and Six Months After Obesity Surgery.

Purpose: Previous research on obesity surgery (OS) showed that patients do not only experience weight loss but also improvements in certain mental health outcomes (e.g., depression) after OS.

Postoperative Dumping Syndrome, Health-Related Quality of Life, Anxiety, Depression, and Eating Disturbances: Results of a Longitudinal Obesity Surgery Study.

Introduction: Given the lack of research on the relationship of post-surgery dumping syndrome and eating disturbances, the purpose of the present longitudinal study was to investigate whether dumping after obesity surgery is associated with pre-/postoperative eating disorder symptoms or addiction-like eating beyond the type of surgery, gender, health-realted quality of life (HRQoL) and anxiety/depressive symptoms.

Methods: The study included 220 patients (76% women) before (t0) and 6 months after (t1) obesity surgery (sleeve gastrectomy [n = 152], Roux-en-Y gastric bypass [n = 53], omega loop gastric bypass [n = 15]). The Sigstad Dumping Score was used to assess post-surgery dumping syndrome.

A Randomized Study of Food Pictures-Influenced Decision-Making Under Ambiguity in Individuals With Morbid Obesity.

Background And Aims: In addition to craving responses to salient food cues, the anticipation of short-term rewarding consumption of palatable food may overrun the anticipation of long-term negative consequences of obesity. The present investigation addressed the potential interplay of food cravings and decision-making abilities in individuals with obesity.

Method: Study 1 included 107 bariatric surgery candidates with class 2/3 obesity (OB-group) and study 2 included 54 individuals with normal weight/pre-obesity (nonOB-group).

Regulation of G0/G1 switch gene 2 (G0S2) expression in human adipose tissue.

The G0/G1 switch gene 2 (G0S2) protein attenuated adipose triglyceride lipase (ATGL) activity and decreased lipolysis in rodent and human adipocytes. We hypothesized that G0S2 mRNA expression in human adipose tissue is influenced by depot, adipocyte size, body weight and caloric intake. Adipose tissue samples were obtained during abdominal surgery and by needle biopsy before and 3 h after an extended glucose load in lean subjects.
