Micronutrient status 2 years after bariatric surgery: a prospective nutritional assessment.

Background: Among commonly performed bariatric surgeries, biliopancreatic diversion with duodenal switch (BPD-DS) provides greater weight loss than Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG), with sustained metabolic improvements. However, the risk of long-term nutritional deficiencies due to the hypoabsorptive component of BPD-DS hinders its widespread use.

Objective: The aim of the study was to examine nutritional status over 2 years after BPD-DS, RYGB or SG.

Prevalence of Helicobacter pylori Infection in Bariatric Surgery Patients.

Objective: To determine the rate of histology-proven Helicobacter pylori (HP) infection in patients undergoing bariatric surgery and to identify risk factors for HP infection.

Methods: In a retrospective analysis, patients who underwent bariatric surgery with gastric resection in a single hospital between January 2004 and January 2019 were analyzed. For each patient, a surgical specimen was submitted for anatomopathological examination and analyzed for gastritis or other anomalies.

Impact of weight loss on brain age: Improved brain health following bariatric surgery.

Individuals living with obesity tend to have increased brain age, reflecting poorer brain health likely due to grey and white matter atrophy related to obesity. However, it is unclear if older brain age associated with obesity can be reversed following weight loss and cardiometabolic health improvement. The aim of this study was to assess the impact of weight loss and cardiometabolic improvement following bariatric surgery on brain health, as measured by change in brain age estimated based on voxel-based morphometry (VBM) measurements.

Long Alimentary Limb Duodenal Switch (LADS): an Exploratory Randomized Trial, Results at 2 Years.

Purpose: The effectiveness of the standard biliopancreatic diversion with duodenal switch (BPD/DS) in terms of weight loss has been demonstrated. Increasing the strict alimentary limb length while maintaining the length of the common channel could lead to similar weight loss while reducing side effects.

Materials And Methods: The objective was to evaluate the effect of increasing the strict alimentary limb length on weight loss, comorbidities, nutritional deficiencies, and quality of life 2 years after surgery, compared with standard BPD/DS.

Interleukin-1β and prostaglandin-synthesizing enzymes as modulators of human omental and subcutaneous adipose tissue function.

IL-1β stimulates expression of prostaglandin (PG)-synthesizing enzymes cyclooxygenase (COX)-2 and aldo-keto reductase (AKR)1B1 in human preadipocytes. We aimed to examine the impact of IL-1β, COX-2 and AKR1B1 on markers of human visceral and subcutaneous adipose tissue function, and to assess whether PG synthesis by these enzymes mediates IL-1β effects. Omental and subcutaneous fat samples were obtained from bariatric surgery patients.
