Article Abstract
Background: Obesity affects individuals worldwide and is currently the 5 leading cause of death according to the WHO. Bariatric surgery is an effective strategy that produces durable long-term weight loss. There is a bidirectional interplay between mental health and obesity; with higher depression and anxiety in the obese population as well as significant effects on weight loss for people with mental health disorders.
Objective: Our cross-sectional study aimed to examine psychosocial predictors of cognition for the pre-operative bariatric surgery population and its effect on work productivity.
Methods: Demographic data, perceived cognitive deficits (PDQ-5), depression scale (PHQ-9), anxiety (GAD-7), Quality of life (SF36) and work impairment (LEAPS) was collected from 302 pre-operative bariatric surgery candidates at their initial assessment. Multiple regression was conducted with perceived cognitive deficits as the dependent variable. A secondary analysis was done controlling for anxiety and depression.
Results: Variables that were significantly associated with perceived cognition were anxiety, depression, work productivity and overall mental health quality of life. Perceived cognition was also significantly associated with work impairment independent of mood symptoms.
Discussion: Anxiety and depression are prevalent in the pre-operative bariatric surgery population, significantly affecting cognition, and should be routinely screened. Work performance was also affected by cognition in our population but the link between obesity and cognition needs to be further explored.
Conclusions: We identified a significant association between perceived cognition and psychosocial factors in pre-operative bariatric surgery candidates. Further studies will be needed to better explore obesity and its impact on cognition.
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 %.
