Article Abstract
A single nucleotide polymorphism in the Type 2 deiodinase (DIO2) gene (p.Thr92Ala) was found to be associated with hypertension, type 2 diabetes mellitus (T2DM), insulin resistance, and body mass index (BMI). We retrospectively evaluated 182 patients to assess whether the DIO2 p.Thr92Ala was associated with severe obesity and response to bariatric surgery. Genomic DNA was extracted from peripheral blood leukocytes before surgery. Glycemic control parameters, cardiometabolic risk biomarkers (waist circumference, lipid assessment and blood pressure) and hormonal parameters were assessed at baseline and after surgery. Based on genotype evaluation, 78/182 (42.9%) patients were homozygous wild-type (Thr/Thr), 83/182 (45.6%) heterozygous (Thr/Ala), and 21/182 (11.5%) rare homozygous (Ala/Ala). Age at the time of the first evaluation in our Unit was significantly lower in patients with DIO2 p.Thr92Ala. No significant association was observed between DIO2 p.Thr92Ala and BMI, excess weight, waist circumference, Homa Index. The prevalence of comorbidities was not associated with allele distribution except for hypertension that was more frequent in wild-type patients (p = 0.03). After bariatric surgery, excess weight loss (EWL) % and remission from comorbidities occurred without differences according to genotypes. DIO2 p.Thr92Ala does not affect the severity of obesity and its complications, but it seems to determine an earlier onset of morbid obesity. The presence of polymorphism seems not to impact on the response to bariatric surgery, both in terms of weight loss and remission of comorbidities.
Background: To evaluate the influence of sodium bicarbonate Ringer's solution (BRS) combined with positive end-expiratory pressure (PEEP) on the internal environment in patients who have undergone laparoscopic bariatric surgery.
Methods: A total of 128 patients undergoing laparoscopic bariatric surgery were randomly divided into the control group (group C), the PEEP group (group P), the BRS group (group B), and the BRS combined with the PEEP group (group BP). The results of arterial blood gas analysis, including pH value, base excess (BE), concentrations of electrolyte, and lactate (Lac) were documented before intravenous infusion (T0) and 5 min after the surgery (T1).
Background: The clinical impact of bariatric surgery (BS) prior to pancreas transplantation (PTx) is unclear.
Setting: University of Minnesota Hospital, Minneapolis, MN.
Methods: This was a single center retrospective case-controlled study of all patients January 1, 1998 and May 1, 2024 with a history of BS prior to PTx.
Purpose: Pre-operative eating disorders are well documented within the metabolic and bariatric surgery (MBS) population, yet subthreshold dieting attempts are less understood. The objectives of this study were to define and categorize patients' preoperative dieting attempts, and to determine how attempts are associated with postoperative outcomes, eating disorders, and demographics.
Materials And Methods: Three hundred twenty-one patients (81.
Background: Bariatric surgery is a cornerstone intervention for individuals with severe obesity, offering substantial and sustainable weight loss.
Methods: This retrospective cohort study included 186 patients with obesity and Type2 diabetes who underwent sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) between 2009 and 2020 at University Hospital Ayr. Optimal clinical response weight loss was defined as excess weight loss (%EWL) ≥50 % or total weight loss (%TWL) ≥20 %.
