Objective: Grit is a person's ability to establish long-term goals and work to achieve those goals irrespective of any barriers. We examined the relationship between the personality trait grit, obesity, and metabolic and bariatric surgery (MBS)-induced weight loss.
Methods: In an ongoing prospective cohort, 104 adult patients who underwent laparoscopic sleeve gastrectomy (LSG) had preoperative grit questionnaires administered.
Background: To determine the clinical importance of pneumatosis intestinalis (PI) on surgical decision-making and patient outcomes.
Methods: A matched cohort observational study was conducted including all clinical encounters for both ambulatory and inpatient care at UCLA Health between February 15, 2006 and January 31, 2023. Patients were initially identified using encounter diagnostic codes for "other specified diseases of intestine.
Objective: To assess the external validity of randomized controlled trials (RCTs) of bariatric surgical treatment on diabetes control.
Background: Multisite RCTs provide the strongest evidence supporting clinical treatments and have the greatest internal validity. However, characteristics of trial participants may not be representative of patients receiving treatment in the real world.
Background: Previous clinical studies showing that cinnamon spice lowers blood glucose concentrations had inconsistent results.
Objectives: To determine the effect of daily cinnamon spice supplementation in an amount commonly used for seasoning on glucose concentrations in adults with obesity and prediabetes.
Methods: Following a 2-wk run-in period of maintaining a low polyphenol/fiber diet, 18 participants with obesity and prediabetes underwent a 10-wk randomized, controlled, double-blind, crossover trial (mean age 51.
Objectives: To correlate preoperative imaging of fecaliths with what is seen in surgical specimens.
Background: Early studies considered radiological findings of appendicoliths as a contraindication for nonoperative treatment of appendicitis. There is no standard definition for what is labeled as an appendicolith radiologically and little is known about the pathological correlates of these lesions.
Background: Small bowel obstruction (SBO) is common and its management has evolved in recent years.
Study Design: The literature describing adhesive small bowel obstruction (aSBO) treatment was reviewed, and a formal systematic review was performed to identify publications reporting results of aSBO treatment without NGTs.
Results: The annual rate of hospital admission for SBO in the US has increased, with 340,100 admissions in 2019 alone.
Objective: In a large multisite cohort of Veterans who underwent Roux-en-Y gastric bypass (RYGB) or laparoscopic sleeve gastrectomy (LSG), initiation of (ie, incident) and persistence of (ie, continuation of preoperative) depression treatment are compared with matched nonsurgical controls.
Background: Bariatric surgery has been associated with short-term improvements in depression but less is known about longer term outcomes.
Methods: In a retrospective cohort study, we matched 1713 Veterans with depression treatment who underwent bariatric surgery in Veterans Administration bariatric centers from fiscal year 2001 to 2016 to 15,056 nonsurgical controls using sequential stratification and examined the persistence of depression treatment via generalized estimating equations.
Objective: To better understand the efficacy of water-soluble contrast (WSC) in the treatment of adhesive small bowel obstruction (SBO).
Background: Guidelines recommend using WSC to treat adhesive SBO nonoperatively by acting as a cathartic agent. The evidence supporting this practice is mixed.
Objective: To evaluate survival outcomes associated with perioperative allogeneic red blood cell transfusion (RBCT) in patients with pancreatic ductal adenocarcinoma undergoing surgery.
Methods: PubMed, Embase, Cochrane, and Web of Science Core Collection were queried for English-language articles until May 28, 2020. Studies evaluating long-term outcomes of RBCT compared with no transfusion in adults with pancreatic ductal adenocarcinoma undergoing pancreatectomy were included.
Importance: Bariatric surgical procedures have been associated with increased risk of unhealthy alcohol use, but no previous research has evaluated the long-term alcohol-related risks after laparoscopic sleeve gastrectomy (LSG), currently the most used bariatric procedure. No US-based study has compared long-term alcohol-related outcomes between patients who have undergone Roux-en-Y gastric bypass (RYGB) and those who have not.
Objective: To evaluate the changes over time in alcohol use and unhealthy alcohol use from 2 years before to 8 years after a bariatric surgical procedure among individuals with or without preoperative unhealthy alcohol use.
Background: Opioid analgesics are often prescribed to manage pain after bariatric surgery, which may develop into chronic prescription opioid use (CPOU) in opioid-naïve patients. Bariatric surgery may affect opioid use in those with or without presurgical CPOU.
Objective: To compare CPOU persistence and incidence in a large multisite cohort of veterans undergoing bariatric surgery (open Roux-en-Y gastric bypass, laparoscopic RYGB, or laparoscopic sleeve gastrectomy) and matched nonsurgical controls.
This cohort study uses gap decomposition analysis to ascertain the factors associated with postoperative mortality in patients with heart failure.
