Setting: Academic and private practice bariatric surgery programs participating in a statewide quality improvement collaborative.

The impact of social determinants of health (SDOH) on completing bariatric surgery at a single academic institution.

Background: Underutilization of bariatric surgery is multifactorial. This study aimed to understand the association of SDOH on not achieving surgery.

Methods: 1081 applications for primary MBS from January-December 2021 were stratified into those that completed surgery (COM; n = 415), in progress > 1-year (IP; n = 107), dropped out (DO; n = 379), and never started (NS; n = 180).

American Society for Metabolic and Bariatric Surgery literature review on risk factors, screening recommendations, and prophylaxis for marginal ulcers after metabolic and bariatric surgery.

Background: Marginal ulcers (MU) are a significant postoperative complication following anastomotic metabolic and bariatric surgeries including Roux-en-Y gastric bypass (RYGB), one-anastomosis gastric bypass (OAGB), and biliopancreatic diversion with duodenal switch (BPD/DS). This review summarizes current knowledge on MU risk factors, screening, and prophylactic strategies.

Objectives: The goal of this review is to examine technical and patient-related risk factors for MU, assess screening strategies, and recommend prophylactic approaches to reduce MU incidence after anastomotic metabolic and bariatric surgery (MBS).

ASMBS literature review on the treatment of marginal ulcers after metabolic and bariatric surgery.

Marginal ulcers (MUs) encompass a group of mucosal disruptions and subsequent inflammatory changes and their sequala found after Roux-en-Y gastric bypass (RYGB) oneanastomosis gastric bypass (OAGB), and, less commonly, after biliopancreatic diversion with duodenal switch (BPD/DS) or single anastomosis duodeno-ileostomy with sleeve gastrectomy (SADI-S). Prevalence of MU after RYGB ranges from .6%-16%.

Changes in anthropometry, adiposity, and inflammation in Black and White women engaged in intentional weight loss.

Objective: We examined associations among changes in anthropometry, regional adiposity, and inflammatory markers in Black and White women participating in intentional weight loss.

Methods: A total of 104 women with BMI ≥ 25 kg/m self-selected bariatric surgery (n = 66) or a diet and exercise program (n = 38). Anthropometric, dual-energy x-ray absorptiometry-quantified regional adiposity, and inflammatory markers (C-reactive protein [CRP], tumor necrosis factor α [TNF-α], soluble TNF receptor I [sTNFRI], sTNFRII, interleukin [IL]-6, and soluble IL-1 receptor antagonist) were measured at baseline and 6 months.

Obesity-associated microbiomes instigate visceral adipose tissue inflammation by recruitment of distinct neutrophils.

Neutrophils are increasingly implicated in chronic inflammation and metabolic disorders. Here, we show that visceral adipose tissue (VAT) from individuals with obesity contains more neutrophils than in those without obesity and is associated with a distinct bacterial community. Exploring the mechanism, we gavaged microbiome-depleted mice with stool from patients with and without obesity during high-fat or normal diet administration.

Novel multiparametric bulk and single EV pipeline for adipose cell-specific biomarker discovery in paired human biospecimens.

Obesity is a global health crisis that contributes to morbidity and mortality worldwide. Obesity's comorbid association with a variety of diseases, from metabolic syndrome to neurodegenerative disease, underscores the critical need to better understand the pathobiology of obesity. Adipose tissue, once seen as an inert storage depot, is now recognized as an active endocrine organ, regulating metabolic and systemic homeostasis.

Transportation Factors and Postoperative Attendance and Weight Loss Through 24 Months.

Purpose: Transportation, access to follow-up care, and association with weight loss are understudied in the bariatric population. The objective of this study was to determine how transportation variables associate with postoperative attendance and weight loss through 24 months.

Materials And Methods: Seven hundred eighty-seven patients (81.

Breastfeeding following bariatric surgery among obese women with and without diabetes mellitus.

Background: Information on exclusive breastfeeding (BF) and BF initiation following bariatric surgery (BS) among obese women with diabetes mellitus (DM) and without DM (non-DM) is limited.

Methods: Retrospective cohort study. Obesity was defined by BMI (kg/m2) as grade 1 (30-34.

Distinctive patterns of sulfide- and butyrate-metabolizing bacteria after bariatric surgery: potential implications for colorectal cancer risk.

Despite improved cardiometabolic outcomes following bariatric surgery, its long-term impact on colorectal cancer (CRC) risk remains uncertain. In parallel, the influence of bariatric surgery on the host microbiome and relationships with disease outcomes is beginning to be appreciated. Therefore, we investigated the impact of Roux-en-Y gastric bypass (RYGB) and vertical sleeve gastrectomy (VSG) on the patterns of sulfide-reducing and butyrate-producing bacteria, which are hypothesized to modulate CRC risk after bariatric surgery.

Mid-term Outcomes of Nissen Fundoplication Versus Roux-en-y Gastric Bypass for Primary Management of Gastroesophageal Reflux Disease in Patients With Obesity.

Introduction: The efficacy and outcomes of laparoscopic Nissen fundoplication (LNF) in patients with obesity is controversial. Specifically, concerns regarding long-term outcomes and recurrence in the setting of obesity has led to interest in laparoscopic Roux-en-Y gastric bypass (RYGB).

Methods: In this retrospective cohort study, we studied patients with obesity who underwent either LNF or RYGB for gastroesophageal reflux disease.

Social History of Bariatric Surgery: Relationship to Patient and Associations with Postoperative Outcomes.

Purpose: There is limited research about the prevalence of patients initiating metabolic and bariatric surgery (MBS) who also know someone who had MBS, referred to as having a social history of MBS. Evidence about the specific relationship of these individuals to the patient, how having a social history of MBS is associated with patients' choice of surgical procedure, and how having a social history of MBS is associated with patients' postoperative outcomes can be used to inform future preoperative assessments. The objective was to (a) define the number of people patients knew who had MBS and relationship to patient, (b) assess congruence between those who had MBS with patients' procedure selection, and (c) explore associations between social history of MBS and postoperative outcomes.

Bariatric Patient Engagement in a Pre-surgery Virtual Patient Navigation Platform (VPNP).

Background: This study analyzed patient engagement with a virtual patient navigation platform (VPNP) designed to help guide bariatric surgery candidates through the complex pre-operative workup for surgery.

Methods: Data on baseline sociodemographic and medical history was collected on patients enrolled in the bariatric program at a single academic institution between March and May 2021. The System Usability Scale (SUS) survey was administered to assess VPNP usability.

Proximity to High/Moderate vs Low Diversity Selection Food Stores and Patient Weight loss through 24 Months.

Purpose: Explorations into the neighborhood food environment have not adequately extended to adults with obesity who undergo bariatric surgery. The objective of this study is to determine how diversity of food selection at food retail stores within proximities of 5- and 10-min walks associate with patient postoperative weight loss over 24 months.

Materials And Methods: Eight hundred eleven patients (82.

Weight Regain After Bariatric Surgery: Scope of the Problem, Causes, Prevention, and Treatment.

Purpose Of Review: Although bariatric surgery is the most effective treatment of severe obesity, a proportion of patients experience clinically significant weight regain (WR) with further out from surgery. The purpose of this review is to summarize the prevalence, predictors, and causes of weight regain.

Recent Findings: Estimating the prevalence of WR is limited by a lack of consensus on its definition.

The BARI-hoods Project: neighborhood social determinants of health and postoperative weight loss using integrated electronic health record, census, and county data.

Background: While social determinants of health (SDoH) have gained attention for their role in weight loss following bariatric surgery, electronic health record (EHR) data provide limited information beyond demographics associated with disparities in weight loss.

Objective: To integrate EHR, census, and county data to explore disparities in SDoH and weight loss among patients in the largest populous county of Ohio.

Setting: Seven hundred seventy-two patients (82.

Associations between psychological evaluation outcomes, psychiatric diagnoses, and outcomes through 12 months after bariatric surgery.

Background: There is limited evidence about how patients' initial preoperative psychological evaluation outcomes (require follow-up [RFU], no required follow-up [NFU], and place on hold [POH]) and current psychiatric diagnoses associate with postoperative outcomes.

Objectives: To test the hypotheses that patients who receive a clinical decision of RFU versus NFU from their initial psychological evaluation will be (1) more likely to experience postoperative complications, readmissions, and emergency room visits and (2) experience less weight loss over 12-months. Specific diagnoses (any psychiatric diagnosis, depression, and anxiety) are also examined for their association with weight loss over 12 months.

Preoperative Psychological Evaluation Outcomes, Reasoning, and Demographic and Diagnostic Correlates.

Purpose: Little is known about associations between preoperative psychiatric, disordered eating, and substance use diagnoses with the clinical decision to require follow-up after the preoperative psychological evaluation. To determine the proportion of patients who require follow-up (no required follow-up (NFU), required follow-up (RFU), placed on hold (POH)) from the preoperative psychological evaluation, associations with diagnoses, and noted reasons for follow-up.

Materials And Methods: The sample included 508 patients (77.

Impact of post-discharge phone calls on non-urgent hospital returns < 90 days following primary bariatric surgery.

Introduction: Quality of care delivery may improve patient outcomes post-bariatric surgery. We examined the quality of post-discharge phone calls (Ph) to determine the impact on early (< 90 day) non-urgent hospital returns (NUHR) following primary bariatric surgery.

Methods: A retrospective review was performed on patients who underwent Roux-en-Y-gastric bypass (RYGB) or sleeve gastrectomy (SG) in 2019.

Interferon gamma mediates the reduction of adipose tissue regulatory T cells in human obesity.

Decreased adipose tissue regulatory T cells contribute to insulin resistance in obese mice, however, little is known about the mechanisms regulating adipose tissue regulatory T cells numbers in humans. Here we obtain adipose tissue from obese and lean volunteers. Regulatory T cell abundance is lower in obese vs.

Changes in Child Weight, Behaviors, and Family Dynamics during Parental Participation in a Medical Weight Management Program: A Longitudinal Uncontrolled Pilot Study.

There is limited evidence of the effects of parental participation in outpatient medical weight management (MWM) programs on children. The aims of the project were to (1) identify time effects from parental participation in the MWM program on changes in child weight trajectories, healthy and unhealthy weight control practices, physical and sedentary activity, parental restrictive feeding and pressure to eat, and family functioning and communication and (2) determine differences based on child factors. A longitudinal uncontrolled pilot study was conducted, in which parent-child (ages 7-19) dyads completed assessments at parents' MWM program initiation, 3 months (mid-program), 6 months (end of program), and 12 months to determine sustained effects.
