Associations of weather and air pollution with objective physical activity and sedentary time before and after bariatric surgery: a secondary analysis of a prospective cohort study.

Purpose: Identifying factors that influence moderate-to-vigorous intensity physical activity (MVPA) and sedentary time in metabolic and bariatric surgery (MBS) patients is necessary to inform the development of interventions. Weather/environmental factors may be especially important considering rapid climate change and the vulnerability of people with obesity to heat and pollution. Our study aimed to examine the associations of weather (maximal, average and Wet Bulb Globe Temperatures), and air pollution indices (air quality index [AQI]) with daily physical activity (PA) of both light (LPA) and MVPA and sedentary time before and after MBS.

Scientific evidence for the updated guidelines on indications for metabolic and bariatric surgery (IFSO/ASMBS).

The 2022 American Society for Metabolic and Bariatric Surgery (ASMBS) and International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) updated the indications for metabolic and bariatric surgery (MBS), replacing the previous guidelines established by the National Institutes of Health (NIH) over 30 years ago. The evidence supporting these updated guidelines has been strengthened to assist metabolic and bariatric surgeons, nutritionists, and other members of multidisciplinary teams (MDTs), as well as patients. This study aims to assess the level of evidence and the strength of recommendations compared to the previously published criteria.

Transcranial Magnetic Stimulation for Reducing the Relative Reinforcing Value of Food in Adult Patients With Obesity Pursuing Metabolic and Bariatric Surgery: Protocol for a Pilot, Within-Participants, Sham-Controlled Trial.

Background: Metabolic and bariatric surgery (MBS) is the most effective and durable obesity treatment. However, there is heterogeneity in weight outcomes, which is partially attributed to variability in appetite and eating regulation. Patients with a strong desire to eat in response to the reward of palatable foods are more likely to overeat and experience suboptimal outcomes.

Associations of weather and air pollution with objective physical activity and sedentary time before and after bariatric surgery: a secondary analysis of a prospective cohort study.

Background--: Most metabolic and bariatric surgery (MBS) patients perform too little moderate-to-vigorous intensity physical activity (MVPA) and too much sedentary time (ST). Identifying factors that influence MVPA and ST in MBS patients is necessary to inform the development of interventions to target these behaviors. Research has focused on individual-level factors and neglected those related to the physical environment (e.

Incidence of Hiatal Hernia Repair During Primary Bariatric Surgery Conversion: an Analysis of the 2020 MBSAQIP Database.

The rate of hiatal hernia (HH) repair during conversion bariatric surgery is largely unknown. We sought to determine this rate in 12,788 patients undergoing conversion surgery using the 2020 participant use file of the MBSAQIP database. Concurrent HH repair was performed in 24.

Ecological momentary assessment of changes in eating behaviors, appetite, and other aspects of eating regulation in Roux-en-Y gastric bypass and sleeve gastrectomy patients.

Bariatric surgery can have profound impacts on eating behaviors and experiences, yet most prior research studying these changes has relied on retrospective self-report measures with limited precision and susceptibility to bias. This study used smartphone-based ecological momentary assessment (EMA) to evaluate the trajectory of change in eating behaviors, appetite, and other aspects of eating regulation in 71 Roux-en-Y gastric bypass and sleeve gastrectomy patients assessed preoperatively and at 3, 6, and 12-months postoperative. For some outcomes, results showed a consistent and similar pattern for SG and RYGB where consumption of sweet and high-fat foods and hunger, desire to eat, ability to eat right now, and satisfaction with amount eaten all improved from pre-to 6-months post-surgery with some degree of deterioration at 12-months post-surgery.

Exercise for counteracting weight recurrence after bariatric surgery: a systematic review and meta-analysis of randomized controlled trials.

Exercise is recommended to prevent post-surgical weight recurrence. Yet, whether exercise interventions are efficacious in this regard has not been systematically evaluated. Moreover, clinicians lack evidence-based information to advise patients on appropriate exercise frequency, intensity, time, and type (FITT) for preventing weight recurrence.

Food cue reactivity in successful laparoscopic gastric banding: A sham-deflation-controlled pilot study.

Laparoscopic adjustable gastric banding (LAGB) offers a unique opportunity to examine the underlying neuronal mechanisms of surgically assisted weight loss due to its instant, non-invasive, adjustable nature. Six participants with stable excess weight loss (%EWL ≥ 45) completed 2 days of fMRI scanning 1.5-5 years after LAGB surgery.

Experienced weight stigma, internalized weight bias, and clinical attrition in a medical weight loss patient sample.

Background: Limited research has explored the relationship between weight bias and clinical attrition, despite weight bias being associated with negative health outcomes.

Participants/method: Experienced weight stigma (EWS), internalized weight bias (IWB), and clinical attrition were studied in a Medical Weight Loss clinic, which combines pharmacological and behavioral weight loss. Patient sociodemographic, medical, and psychological (depression) variables were measured at consultation, and clinic follow-ups were monitored for 6 months.

Brain responses to anticipatory cues and milkshake taste in obesity, and their relationship to bariatric surgery outcome.

There is substantial variability in percent total weight loss (%TWL) following bariatric surgery. Functional brain imaging may explain more variance in post-surgical weight loss than psychological or metabolic information. Here we examined the neuronal responses during anticipatory cues and receipt of drops of milkshake in 52 pre-bariatric surgery men and women with severe obesity (OW, BMI = 35-60 kg/m) (23 sleeve gastrectomy (SG), 24 Roux-en-Y gastric bypass (RYGB), 3 laparoscopic adjustable gastric banding (LAGB), 2 did not undergo surgery) and 21 healthy-weight (HW) controls (BMI = 19-27 kg/m).

C Peptide Fails to Improve the Utility of the DiaRem Algorithm in Predicting Remission of Type II Diabetes After Bariatric Surgery.

We evaluated the utility of C peptide as an addition to the DiaRem score for predicting type 2 diabetes (T2D) remission 1 year after bariatric surgery in 175 patients. DiaRem score was significantly correlated with C peptide (r = - .43; p < .

Use of an Endoscopic Suturing Platform for the Management of Staple Line Dehiscence After Laparoscopic Sleeve Gastrectomy.

Background: Management of staple line dehiscence following laparoscopic sleeve gastrectomy (LSG) varies based on local expertise and timing of presentation. We present our experience with an endoscopic suturing platform to treat patients with staple line dehiscence following LSG.

Methods: We included all patients who presented to our institution with a staple line dehiscence following LSG from 2005 through November 2017.

Effects of statin therapy on weight loss and diabetes in bariatric patients.

Background: Bariatric surgeries are considered effective treatments for weight loss and improved diabetes control. Statins increase diabetes onset in prospective clinical trials and many bariatric patients with metabolic disease are concurrently on statins.

Objectives: We retrospectively examined the relationship of statin therapy to weight loss, diabetes mellitus onset and remission, and metabolic outcomes after bariatric surgery.

Gastric bypass surgery as treatment of recalcitrant gastroparesis.

Background: Few treatments for idiopathic and diabetic gastroparesis exist beyond symptom management, and no study has described gastric surgery for gastroparesis in obese and morbidly obese patients. The objective of this study was to describe treatment of recalcitrant gastroparesis in obese adults with Roux-en-Y gastric bypass (RYGB) surgery.

Methods: A retrospective review was conducted of adult patients who underwent laparoscopic RYGB.

Retained needles in laparoscopic surgery: open or observe?

Background: Currently, there is no standard of care on how to manage a retained needle or foreign body (RFB) during laparoscopic surgery.

Methods: A survey presented a relevant case and 18 multiple-choice and open-response questions about personal experience with and attitudes toward RFBs, clinical practices, and management.

Results: From 10/2009-2/2010 we received 255 survey responses.

Laparoscopic placement of adjustable gastric band in patients with autoimmune disease or chronic steroid use.

Background: Past medical or family history of autoimmune diseases and patient chronic steroid use are label contraindications for laparoscopic placement of adjustable gastric band (LAGB). We reviewed our experience with placement of LAGB in patients with autoimmune disease or chronic steroid use.

Methods: This was a retrospective review of our prospective bariatric database.

Pharmacokinetics of intravenous linezolid in moderately to morbidly obese adults.

The pharmacokinetics of linezolid was assessed in 20 adult volunteers with body mass indices (BMI) of 30 to 54.9 kg/m(2) receiving 5 intravenous doses of 600 mg every 12 h. Pharmacokinetic analyses were conducted using compartmental and noncompartmental methods.

Effect of immunosuppression on patients undergoing bariatric surgery.

Background: Immunocompromised patients are at high risk of medical complications. Immunosuppression might be a relative contraindication to bariatric surgery. We describe our experience with immunosuppressed patients undergoing bariatric surgery and review the safety, efficacy, results, and outcomes.

Obesity surgery and malignancy: our experience after 1500 cases.

Background: Obesity is a risk factor for cancer and is associated with increased mortality from a number of malignancies. We describe our experience with bariatric surgery patients with a history of malignancy and review the safety and outcomes of bariatric surgery in patients with a history of cancer.

Methods: We performed a retrospective review of prospectively collected data from all patients diagnosed with a malignancy before, during, or after bariatric surgery.
