Diet-Induced Alteration of Microbiota and Development of Obesity, Nonalcoholic Fatty Liver Disease, and Diabetes: Study Protocol of a Prospective Study.

Background: Development of obesity and obesity-related diseases, such as type 2 diabetes mellitus and nonalcoholic fatty liver disease (NAFLD), is associated with altered gut microbiota composition. The aim of this study is to investigate associations among dietary compounds, intestinal cell function, and gut microbiota composition. We hypothesize that dietary lipid intake is associated with Paneth cell and goblet cell properties that affect gut microbiota composition.

Laparoscopic Adjustable Gastric Banding After Failed Roux-En-Y Gastric Bypass.

Background: Roux-en-Y gastric bypass (RYGB) is associated with approximately 25 % weight loss failure, resulting in insufficient weight loss or weight regain. Strategies of revisional surgery focus on alteration of limb length, pouch or stoma size. Altering pouch size and outlet by adding laparoscopic adjustable gastric band (LAGB) might initiate further weight loss.
