Lancet Gastroenterol Hepatol 2024; 9:957-964. [PMID: 39096914 DOI: 10.1016/s2468-1253(24)00188-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/12/2024] [Revised: 05/28/2024] [Accepted: 05/29/2024] [Indexed: 08/05/2024]
Abstract
The availability of glucagon-like peptide-1 (GLP-1) receptor agonists (RAs) such as liraglutide and semaglutide, and a GLP-1 and glucose dependent insulinotropic polypeptide coagonist (tirzepatide) represents a paradigm shift in the management of both type 2 diabetes and obesity. There is now considerable attention, including in the public media, on the effect of both long-acting and short-acting GLP-1RAs to delay gastric emptying. Although slowed gastric emptying is integral to reducing post-prandial blood glucose responses in type 2 diabetes, marked slowing of gastric emptying might also increase the propensity for longer intragastric retention of food, with a consequent increased risk of aspiration at the time of surgery or upper gastrointestinal endoscopy. This Personal View summarises current knowledge of the effects of GLP-1 and GLP-1RAs on gastrointestinal physiology, particularly gastric emptying, and discusses the implications for the development of sound pre-operative or pre-procedural guidelines. The development of pre-procedural guidelines is currently compromised by the poor evidence base, particularly in relation to the effect of long-acting GLP-1RAs on gastric emptying. We suggest pre-procedural management pathways for individuals on GLP-1RA-based therapy and discuss priorities for future research.

Effect of oral semaglutide on energy intake, appetite, control of eating and gastric emptying in adults living with obesity: A randomized controlled trial. Diabetes Obes Metab 2024; 26:4480-4489. [PMID: 39082206 DOI: 10.1111/dom.15802] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2024] [Revised: 06/21/2024] [Accepted: 06/30/2024] [Indexed: 09/19/2024]
Abstract
AIM To investigate the effects of once-daily oral semaglutide 50 mg on energy intake, appetite, control of eating and gastric emptying. METHODS A clinical pharmacology, double-blind study was conducted in 61 adults with obesity randomized to once-daily oral semaglutide (dose-escalated to 50 mg) or placebo for 20 weeks. Energy intake was measured during an ad libitum lunch, and participant-reported appetite ratings and Control of Eating Questionnaire responses were assessed. Gastric emptying was measured using paracetamol absorption following a standardized breakfast. RESULTS The relative change from baseline in ad libitum energy intake at week 20 (primary endpoint) was -39.2% points (95% confidence interval -59.0%, -19.4%) with semaglutide compared with placebo. Body weight was reduced by 9.8% with semaglutide and by 1.5% with placebo. Semaglutide reduced hunger, increased fullness and satiety, and was associated with fewer food cravings and better control of eating versus placebo. No statistically significant difference in gastric emptying was observed at week 20. CONCLUSIONS In participants with obesity, once-daily oral semaglutide 50 mg reduced energy intake, body weight and appetite, and improved control of eating. There was no evidence of delayed gastric emptying at week 20, as measured through paracetamol absorption.

Abstract
Excess adiposity is at the root of type 2 diabetes (T2D). Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have emerged as first-line treatments for T2D based on significant weight loss results. The composition of weight loss using most diets consists of <25% fat-free mass (FFM) loss, with the remainder from fat stores. Higher amounts of weight loss (achieved with metabolic bariatric surgery) result in greater reductions in FFM. Our aim was to assess the impact that GLP-1RA-based treatments have on FFM. We analysed studies that reported changes in FFM with the following agents: exenatide, liraglutide, semaglutide, and the dual incretin receptor agonist tirzepatide. We performed an analysis of various weight loss interventions to provide a reference for expected changes in FFM. We evaluated studies using dual-energy X-ray absorptiometry (DXA) for measuring FFM (a crude surrogate for skeletal muscle). In evaluating the composition of weight loss, the percentage lost as fat-free mass (%FFML) was equal to ΔFFM/total weight change. The %FFML using GLP-1RA-based agents was between 20% and 40%. In the 28 clinical trials evaluated, the proportion of FFM loss was highly variable, but the majority reported %FFML exceeding 25%. Our review was limited to small substudies and the use of DXA, which does not measure skeletal muscle mass directly. Since FFM contains a variable amount of muscle (approximately 55%), this indirect measure may explain the heterogeneity in the data. Assessing quantity and quality of skeletal muscle using advanced imaging (magnetic resonance imaging) with functional testing will help fill the gaps in our current understanding.

Abstract
Obesity, a pervasive global health challenge affecting more than two billion people, requires comprehensive interventions. Traditional approaches, including lifestyle modification, and diverse drugs targeting a gastrointestinal hormone, including glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) (Liraglutide, Semaglutide, Exenatide, Albiglutide, Dulaglutide, Lixisenatide, Orlistat, Phentermine/Topiramate, Lorcaserin, Sibutramine, Rimonabant) offer tailored strategies; yet their effectiveness is limited and some drugs were taken off the market. Moreover, various surgical modalities, such as Roux-en-Y Bypass surgery, sleeve gastrectomy, intragastric balloons, biliopancreatic diversion with duodenal switch (BPD/DS), laparoscopic adjustable gastric band (LAGB), and vagal nerve blockade can be considered but are associated with numerous side effects and require careful monitoring. Consequently, there is a pressing need for novel anti-obesity treatments. In this landscape, tirzepatide, initially designed for type 2 diabetes (T2D) management, emerges as a potential game-changer. Functioning as a dual GIP/GLP-1 receptor agonist, it not only addresses control but also introduces a fresh perspective on weight reduction. This review intricately explores tirzepatide's mechanism, dissecting insights from clinical studies and positioning it as a major force in obesity treatment. In the middle of significant shifts in obesity management, tirzepatide presents itself as a promising and cost-effective intervention. Its Food and Drug Administration (FDA) approval marks a milestone in the realm of obesity therapeutics. Going beyond a recapitulation of findings, the conclusion emphasizes the imperative for ongoing exploration and vigilant safety monitoring in tirzepatide's application.

Real-World Impact of GLP-1 Receptor Agonists on Endoscopic Patient Outcomes in an Ambulatory Setting: A Retrospective Study at a Large Tertiary Center. J Clin Med 2024; 13:5403. [PMID: 39336890 PMCID: PMC11432687 DOI: 10.3390/jcm13185403] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2024] [Revised: 09/02/2024] [Accepted: 09/10/2024] [Indexed: 09/30/2024] Open
Abstract
Background: Glucagon-like peptide receptor agonists (GLP-1 RAs) are associated with delayed gastric emptying and may increase the risk of aspiration due to retained gastric contents. There are no guidelines on peri-endoscopic use of GLP-1 RAs, and real-world outcomes in an ambulatory setting remain unknown. This study reports real-world data from an ambulatory center associated with a large tertiary hospital. Methods: A retrospective review of electronic medical records was conducted for patients who underwent esophagogastroduodenoscopy (EGD) at a hospital-based outpatient center from January to June 2023. Exclusions included non-elective procedures, current opioid use, altered foregut anatomy, and known gastroparesis. All patients were on GLP-1 RAs before endoscopy and followed standard fasting protocols. Adverse event rates were recorded, and patients were divided into cohorts based on GLP-1 RA use. Univariate and multivariate regression analyses identified risk factors for food retention and complications. Results: A total of 1438 patients underwent elective EGD during the study period. Among the 1046 patients included, 73 (7%) were on GLP-1 RAs. The procedure was aborted in four patients (0.4%) due to gastric food retention, with two (50%) on GLP-1 RAs. Independent risk factors for food retention included GLP-1 RA use (OR: 9.19; 95% CI: 2.73-30.8; p = 0.0003) and diabetes (OR 5.6; 95% CI: 1.72-18.2; p = 0.004). Tirzepatide showed the strongest association (p = 0.0056). Factors that did not impact food retention included A1c, BMI, and gender. Protective factors were age (OR 0.96; 95% CI: 0.93-0.99; p = 0.02) and same-day colonoscopy (OR 0.18; 95% CI: 0.06-0.58; p = 0.003). Conclusions: GLP-1 RA use in diabetics increases the risk of retained gastric contents during elective EGD, particularly with tirzepatide, without increasing aspiration risk. Patients undergoing simultaneous colonoscopy had a lower risk of retained gastric contents. Further studies are needed to evaluate the impact of GLP-1 RAs on gastric food retention and procedural risk.

Abstract
Background Obesity and type 2 diabetes mellitus (T2DM) are increasingly common in the United States and worldwide. Because both conditions are associated with serious health consequences, weight reduction is recommended by professional medical and nutrition societies to improve outcomes. Due to the striking efficacy of glucagon-like peptide receptor agonists (GLP-1RAs) and dual mechanism glucose-dependent insulinotropic polypeptide/glucagon-like peptide receptor agonists (GIP/GLP-1RAs) for weight reduction and glycemic control, there is increased utilization for patients with obesity and/or T2DM. Yet, the impact of these medications on dietary intake is less understood. Methods This narrative literature review summarizes clinical studies quantifying and characterizing dietary intake in people with obesity and/or T2DM using GLP-1 or GIP/GLP-1 RAs. Results Though data from these studies reveal that total caloric intake was reduced by 16-39 %, few studies evaluated the actual composition of the diet. Conclusions Further research is needed to understand the unique nutritional needs of adults on GLP-1 or dual GIP/GLP-1RAs and to support the development of nutritional guidelines for these individuals.

Abstract
The improved efficacy and generally favorable safety profile of recently approved and emerging antiobesity medications (AOMs), which result in an average weight reduction of ≥15%, represent significant advancement in the treatment of obesity. This narrative review aims to provide practical evidence-based recommendations for nutritional assessment, management, and monitoring of patients treated with AOMs. Prior to treatment, clinicians can identify preexisting nutritional risk factors and counsel their patients on recommended intakes of protein, dietary fiber, micronutrients, and fluids. During treatment with AOMs, ongoing monitoring can facilitate early recognition and management of gastrointestinal symptoms or inadequate nutrient or fluid intake. Attention should also be paid to other factors that can impact response to treatment and quality of life, such as physical activity and social and emotional health. In the context of treatment with AOMs, clinicians can play an active role in supporting their patients with obesity to improve their health and well-being and promote optimal nutritional and medical outcomes.

Abstract
This consensus statement is a comprehensive update of the 2010 Society for Ambulatory Anesthesia (SAMBA) Consensus Statement on perioperative blood glucose management in patients with diabetes mellitus (DM) undergoing ambulatory surgery. Since the original consensus guidelines in 2010, several novel therapeutic interventions have been introduced to treat DM, including new hypoglycemic agents and increasing prevalence of insulin pumps and continuous glucose monitors. The updated recommendations were developed by an expert task force under the provision of SAMBA and are based on a comprehensive review of the literature from 1980 to 2022. The task force included SAMBA members with expertise on this topic and those contributing to the primary literature regarding the management of DM in the perioperative period. The recommendations encompass preoperative evaluation of patients with DM presenting for ambulatory surgery, management of preoperative oral hypoglycemic agents and home insulins, intraoperative testing and treatment modalities, and blood glucose management in the postanesthesia care unit and transition to home after surgery. High-quality evidence pertaining to perioperative blood glucose management in patients with DM undergoing ambulatory surgery remains sparse. Recommendations are therefore based on recent guidelines and available literature, including general glucose management in patients with DM, data from inpatient surgical populations, drug pharmacology, and emerging treatment data. Areas in need of further research are also identified. Importantly, the benefits and risks of interventions and clinical practice information were considered to ensure that the recommendations maintain patient safety and are clinically valid and useful in the ambulatory setting. What Other Guidelines Are Available on This Topic? Since the publication of the SAMBA Consensus Statement for perioperative blood glucose management in the ambulatory setting in 2010, several recent guidelines have been issued by the American Diabetes Association (ADA), the American Association of Clinical Endocrinologists (AACE), the Endocrine Society, the Centre for Perioperative Care (CPOC), and the Association of Anaesthetists of Great Britain and Ireland (AAGBI) on DM care in hospitalized patients; however, none are specific to ambulatory surgery. How Does This Guideline Differ From the Previous Guidelines? Previously posed clinical questions that were outdated were revised to reflect current clinical practice. Additional questions were developed relating to the perioperative management of patients with DM to include the newer therapeutic interventions.

Abstract
Semaglutide is found to be efficient for weight loss in patients with overweight or obesity with diabetes mellitus (DM). With a wide range of adverse events reported, the efficacy and safety of once-weekly subcutaneous semaglutide in individuals without DM, with overweight or obesity, is unclear. We conducted a comprehensive meta-analysis of randomized studies on once-weekly semaglutide in this patient population. We identified nine studies with 11,641 patients in the semaglutide group and 10,479 in the placebo group. We observed that semaglutide resulted in significant benefits, including change in body weight (%): mean difference (MD) of -11.49% (p < 0.0001), change in absolute body weight: MD of -11.74 kg (p < 0.0001), and change in waist circumference: MD of -9.06 cm (p < 0.0001). Gastrointestinal side effects are predominant including nausea: odds ratio (OR) of 4.06 (p < 0.0001), vomiting: OR of 4.43 (p < 0.0001), diarrhea: OR of 2.10 (p < 0.0001), constipation: OR of 2.43 (p < 0.0001), gallbladder disorders: OR of 1.26 (p = 0.010), and cholelithiasis: OR of 2.06 (p = 0.04). Serious adverse events were not statistically significant: OR of 1.06 (p = 0.82). However, the percentage of participants discontinuing due to adverse events and gastrointestinal side effects was statistically significant: ORs of 2.22 (p < 0.0001) and 3.77 (p < 0.0001), respectively. This study shows that in patients with overweight or obesity without DM, once-weekly subcutaneous semaglutide can significantly decrease body weight without risk of serious adverse events when compared with a placebo. However, gastrointestinal side effects are predominant with semaglutide, which can result in medication discontinuation.

Abstract
INTRODUCTION Glucagon-like peptide-1 receptor agonist (GLP-1A) medications are gaining widespread popularity for the treatment of obesity. The optimal use of these drugs in pediatric bariatric populations, and especially in those considering metabolic and bariatric surgery (MBS), is yet to be established. We sought to characterize current practice patterns of GLP-1A use at major pediatric bariatric centers across the United States. MATERIALS AND METHODS We administered an online survey to a purposive sample of 46 surgeons who perform MBS on children and adolescents. Survey questions explored practices prescribing GLP-1As in patients considering MBS, holding them prior to elective operations, and restarting them postoperatively following MBS. Responses were summarized with descriptive statistics and inductive content analysis. RESULTS There were 22 responses (48% response rate) representing 19 institutions. Most (86%) respondents do sometimes prescribe GLP-1As for patients considering MBS, but the specific indications vary. Practices for holding GLP-1As preoperatively also vary, from not at all to holding for 2 wk. Over half (55%) of respondents sometimes restart GLP-1As after MBS. Free-response themes included still-evolving preoperative utilization patterns, difficulty with access and insurance coverage, and a lack of data informing GLP-1A use in the pre and postoperative periods. CONCLUSIONS Given the increasing use of these medications for weight loss purposes, this substantial variation in practice highlights a need for further research to examine the safest and most effective use of GLP-1As in the pre and postoperative periods and for practice guidelines to standardize care pathways in pediatric bariatric contexts.

Impact of Simulated Caloric Reduction on Nutrient Adequacy Among U.S. Adults with Overweight or Obesity (National Health and Nutrition Examination Survey [NHANES] 2015-2018). J Nutr 2024; 154:2732-2742. [PMID: 39025331 DOI: 10.1016/j.tjnut.2024.07.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2024] [Revised: 07/08/2024] [Accepted: 07/15/2024] [Indexed: 07/20/2024] Open
Abstract
BACKGROUND Current guidelines for the treatment of obesity recommend dietary restriction to create a caloric deficit, and caloric reductions of 16% to 68% have been achieved in adults with overweight or obesity engaging in intentional weight loss programs. OBJECTIVES This study models the impact of simulated caloric reduction on nutrient adequacy among U.S. adults ≥19 y with overweight or obesity using National Health and Nutrition Examination Survey data (2015-2018). METHODS Four levels of caloric reduction (20%, 30%, 40%, and 50%) were modeled by prorating daily calorie intake such that usual intakes of 14 nutrients were reduced proportional to caloric reduction. The percentages below the estimated average requirement (EAR) or above the adequate intake (AI) were estimated at each level of caloric reduction, with and without dietary supplement use. Differences across percentages of simulated caloric reductions were determined using nonoverlapping confidence intervals of the means (97.5th percentile confidence intervals were used to approximate P < 0.05). RESULTS There were significant differences (P < 0.05) in percentages below the EAR (above the AI) between sequential levels of simulated caloric reduction for most of the nutrients analyzed (protein, vitamins A, B-6, folate, and C, calcium, iron, magnesium, potassium, and zinc). For example, after a simulated 30% caloric reduction, 25%-40% of the population had intakes below the EAR for protein, vitamin B-6, and zinc, and 75%-91% of the population had intakes below the EAR for vitamin A, calcium, and magnesium (vs. 4%-18% and 45%-56%, respectively, without caloric reduction). With the inclusion of dietary supplements, percentages below the EAR for all nutrients (except protein) were lower than those for food alone. CONCLUSIONS Caloric reduction may exacerbate nutrient inadequacies among adults with overweight or obesity. Inclusion of nutrient-dense foods, fortified foods, specially formulated products, and/or dietary supplements should be considered for those on calorie-restricted diets for long-term weight loss.

Abstract
Obesity is a chronic and complex disease associated with increased morbidity, mortality, and financial burden. It is expected that by 2030 one of two people in the United States will have obesity. The backbone for obesity management continues to be lifestyle interventions, consisting of calorie deficit diets and increased physical activity levels, however, these interventions are often insufficient to achieve sufficient and maintained weight loss. As a result, multiple patients require additional interventions such as antiobesity medications or bariatric interventions in order to achieve clinically significant weight loss and improvement or resolution of obesity-associated comorbidities. Despite the recent advances in the field of obesity pharmacotherapy that have resulted in never-before-seen weight loss outcomes, comorbidity improvement, and even reduction in cardiovascular mortality, there is still a significant interindividual variability in terms of response to antiobesity medications, with a subset of patients not achieving a clinically significant weight loss. Currently, the trial-and-error paradigm for the selection of antiobesity medications results in increased costs and risks for developing side effects, while also reduces engagement in weight management programs for patients with obesity. The implementation of a precision medicine framework to the selection of antiobesity medications might help reduce heterogeneity and optimize weight loss outcomes by identifying unique subsets of patients, or phenotypes, that have a better response to a specific intervention. The detailed study of energy balance regulation holds promise, as actionable behavioral and physiologic traits could help guide antiobesity medication selection based on previous mechanistic studies. Moreover, the rapid advances in genotyping, multi-omics, and big data analysis might hold the key to discover additional signatures or phenotypes that might respond better to a certain intervention and might permit the widespread adoption of a precision medicine approach for obesity management.

Abstract
AIM To assess whether adults with diabetes on oral hypoglycaemic agents undergoing general endotracheal anaesthesia during nine common surgical procedures who are glucagon-like peptide-1 receptor agonist (GLP1-RA) users, compared with non-users, are at increased risk of six peri- and post-procedure complications. MATERIALS AND METHODS A retrospective observational cohort analysis of over 130 million deidentified US adults with diabetes (defined as being on oral hypoglycaemic agents) from a nationally representative electronic health dataset between 1 January 2015 and 1 April 2023 was analysed. Cohorts were matched by high-dimensionality propensity scoring. We compared the odds of six peri- and postoperative complications in GLP1-RA users and non-users. A sensitivity analysis compared these odds in GLP1-RA users to non-users with diabetes and obesity. We measured the odds of (a) a composite outcome of postoperative decelerated gastric emptying, including antiemetic use, ileus within 7 days post-procedure, gastroparesis diagnosis, gastric emptying study; (b) postoperative aspiration or pneumonitis; (c) severe respiratory failure; (d) postoperative hypoglycaemia; (e) inpatient mortality; and (f) 30-day mortality. RESULTS Among 13 361 adults with diabetes, 16.5% were treated with a GLP1-RA. In the high-dimensionality propensity score-matched cohort, GLP1-RA users had a lower risk of peri- and postoperative complications for decelerated gastric emptying and antiemetic use compared with non-users. The risk of ileus within 7 days, aspiration/pneumonitis, hypoglycaemia and 30-day mortality were not different. A sensitivity analysis showed similar findings in patients with diabetes and obesity. CONCLUSION No increased risk of peri- and postoperative complications in GLP1-RA users undergoing surgery with general endotracheal anaesthesia was identified.

Abstract
This systematic review evaluates the efficacy and safety of semaglutide in individuals with obesity or overweight without diabetes. Obesity is a significant public health concern, associated with various comorbidities and reduced quality of life. Semaglutide, a glucagon-like peptide-1 receptor agonist, has emerged as a promising pharmacological intervention for weight management. This review synthesizes findings from multiple clinical trials, highlighting the impact of semaglutide on weight loss, metabolic parameters, and overall health outcomes in non-diabetic populations. The review also addresses methodological considerations, including study design, participant selection, and outcome measures, to assess the robustness of the evidence. Ethical considerations and potential conflicts of interest are discussed to ensure transparency in the research process. The findings indicate that semaglutide is associated with significant weight reduction and improvement in obesity-related health markers, suggesting its potential as a valuable treatment option for individuals struggling with obesity. Limitations of the current literature and recommendations for future research directions are also presented, emphasizing the need for further studies to explore the long-term effects and generalizability of semaglutide treatment in diverse populations.

Abstract
Binge eating is a central component of two clinical eating disorders: binge eating disorder and bulimia nervosa. However, the large treatment gap highlights the need to identify other strategies to decrease binge eating. Novel pharmacotherapies may be one such approach. Glucagon-like peptide-1 (GLP-1) is an intestinal and brain-derived neuroendocrine signal with a critical role in promoting glycemic control through its incretin effect. Additionally, the energy balance effects of GLP-1 are well-established; activation of the GLP-1 receptor (GLP-1R) reduces food intake and body weight. Aligned with these beneficial metabolic effects, there are GLP-1R agonists that are currently used for the treatment of diabetes and obesity. A growing body of literature suggests that GLP-1 may also play an important role in binge eating. Dysregulation of the endogenous GLP-1 system is associated with binge eating in non-human animal models, and GLP-1R agonists may be a promising approach to suppress the overconsumption that occurs during binge eating. Here, we briefly discuss the role of GLP-1 in normal energy intake and reward and then review the emerging evidence suggesting that disruptions to GLP-1 signaling are associated with binge eating. We also consider the potential utility of GLP-1-based pharmacotherapies for reducing binge eating behavior.

Abstract
PURPOSE We aimed to estimate the association of glucagon-like peptide 1 (GLP-1) receptor agonist therapy with the incidence of endoscopically visible gastric contents after preprocedural fasting. METHODS We reviewed the records of esophagogastroduodenoscopy (EGD) performed at our institution between 2019 and 2023 and determined the presence of residual gastric contents from the procedure notes and saved images. We compared patients taking GLP-1 agonists at the time of the procedure (GLP group, 90 procedures) with patients who started GLP-1 agonist therapy within 1,000 days after undergoing EGD (control, 102 procedures). We excluded emergent procedures without fasting, combined EGD/colonoscopy procedures, and patients with known gastroparesis or previous gastric surgery. We estimated the association between GLP-1 agonist therapy and residual gastric contents with a confounder-adjusted generalized linear mixed effect model. RESULTS Compared with controls, the GLP cohort had a higher age, American Society of Anesthesiologists' Physical Status, and incidence of nausea and diabetes mellitus. Body mass index and fasting duration were comparable between groups. Visible gastric content was documented in 17 procedures in the GLP group (19%) and in five procedures in the control group (5%), with an associated confounder adjusted odds ratio of 5.8 (95% confidence interval, 1.7 to 19.3; P = 0.004). There were five instances of emergent endotracheal intubation in the GLP group vs one case in control and one case of pulmonary aspiration vs none in control. CONCLUSIONS In fasting patients, GLP-1 agonist therapy was associated with an increased incidence of residual gastric contents, potentially posing an additional risk of periprocedural pulmonary aspiration.

Abstract
CONTEXT/OBJECTIVE To describe the effect of semaglutide, a glucagon-like peptide-1 (GLP-1) agonist, to reduce body weight and improve glycemic control in overweight or obese individuals with spinal cord injury (SCI). DESIGN Open-label, randomized drug intervention case series. SETTING This study was performed at James J. Peters VA Medical Center (JJP VAMC) and Kessler Institute for Rehabilitation (KIR). PARTICIPANTS Five individuals with chronic SCI meeting criteria for obesity and abnormal carbohydrate metabolism. INTERVENTION Administration of semaglutide (subcutaneously once per week) versus no treatment (control) for 26 weeks. OUTCOME MEASURES Change in total body weight (TBW), fat tissue mass (FTM), total body fat percent (TBF%), and visceral adipose tissue volume (VATvol) was determined at baseline and after 26 weeks using Dual energy X-ray absorptiometry; fasting plasma glucose (FPG) concentration and serum glycated hemoglobin (HbA1C) values were obtained at the same two time points. RESULTS In 3 participants, after 26 weeks of semaglutide administration, TBW, FTM, TBF%, and VATvol decreased, on average, by 6, 4.4 kg, 1.7%, and 674 cm3, respectively. In addition, values for FPG and HbA1c decreased by 17 mg/dl and 0.2%, respectively. After 26 weeks of observation in the 2 control participants, TBW, FTM, TBF% and VATvol increased on average by 3.3 , 4.5 kg, 2.5%, and 991 cm3, respectively. The average values for FPG and HbA1c also increased by 11 mg/dl and 0.3%, respectively. CONCLUSIONS Administration of semaglutide for 26 weeks resulted in favorable changes in body composition and glycemic control, suggesting a reduced risk for the development of cardiometabolic disease in obese individuals with SCI.Trial registration: ClinicalTrials.gov identifier: NCT03292315.

Abstract
The rising prevalence of obesity has led to a poor quality of life affecting millions worldwide. The lack of a healthy diet and exercise intervention are the major risk factors leading to obesity, as well as genetics. Obesity can lead to type 2 diabetes mellitus. However, there are many people who are obese and do not have an established diagnosis of diabetes but want to reduce their body weight to improve their quality of life. This review aims to discuss the efficacy of the diabetic pharmacologic agents, glucagon-like peptide-1 (GLP-1) receptor agonists, on body weight. The review follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines 2020 and includes a comprehensive search strategy. The articles gathered are from the last five to 10 years. The articles are collected from distinguished databases such as PubMed, Google Scholar, ResearchGate, and Science Direct. Of the 698 studies identified based on the screening methods, 22 were assessed for eligibility and 10 studies were included in the final review. The findings of this systematic review provide a bigger picture of the efficacy and safety of glucagon-like peptide receptor agonist agents. The review thoroughly discusses the risk factors for obesity and provides a treatment strategy that can be utilized in clinical practice in the future. The review concludes that glucagon-like peptide agents act as pharmacologic treatments for reduction in body weight and also serve as cardioprotective agents.

Abstract
BACKGROUND Glucagon-like peptide-1 receptor agonists are used increasingly in the management of patients living with type 2 diabetes mellitus and obesity. In patients using glucagon-like peptide-1 receptor agonists, a key concern in the peri-operative period is the increased risk of pulmonary aspiration due to delayed gastric emptying. This review provides an overview of the pharmacodynamic and pharmacokinetic properties of glucagon-like peptide-1 receptor agonists and the risk of delayed gastric emptying and aspiration. METHODS We conducted searches of MEDLINE and EMBASE databases of articles published before January 2024 using the keywords and medical subject headings: incretins; glucagon-like peptide-1; GLP-1; glucagon-like peptide-1 receptor agonists; GLP-1 RA; peri-operative period; perioperative; peri-operative; stomach emptying; gastric emptying; pulmonary aspiration; aspiration; food regurgitation; and regurgitation. The evidence was analysed, synthesised and reported narratively. RESULTS A total of 1213 articles were located after duplicates were removed. Two authors screened the titles and abstracts to identify those studies which assessed specifically the risk of delayed gastric emptying and pulmonary aspiration or regurgitation in the peri-operative period. We searched manually the reference lists of relevant studies to identify any additional case reports. Ten studies were identified. Available evidence was limited to case reports, case series and observational work. CONCLUSIONS There is insufficient evidence to put forward definitive guidance regarding the ideal cessation period for glucagon-like peptide-1 receptor agonists before elective surgery. Precautionary practice is required until more evidence becomes available. We suggest an individualised, evidence-based approach. In patients living with type 2 diabetes mellitus, there is concern that prolonged cessation before surgery will have a detrimental effect on peri-operative glycaemic control and discussion with an endocrinologist is advised. For patients taking glucagon-like peptide-1 receptor agonists for weight management, these drugs should be withheld for at least three half-lives before an elective surgical procedure.

[PMID: 38753265 DOI: 10.1007/s11695-024-07278-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2024] [Revised: 05/07/2024] [Accepted: 05/09/2024] [Indexed: 07/03/2024]
Abstract
PURPOSE Glucagon-like receptor agonists (GLP1-RAs) have raised peri-procedural concerns due to their potential to delay gastric emptying. The American Association of Anesthesiologists has advised pausing a single dose before elective endoscopy. However, a subsequent directive from multiple gastroenterology societies underscored the need for further assessment to substantiate this practice. We aimed to evaluate the frequency of serious adverse events and retained gastric products during endoscopic sleeve gastroplasty (ESG) with uninterrupted GLP1-RA use. MATERIALS AND METHODS We conducted a retrospective evaluation of all patients undergoing ESG while on GLP1-RAs at three centers from August 2022 to February 2024. Per standard protocol, all patients had refrained from solid foods for at least 24 h and maintained nil per os for 12 h preceding their ESG. Records were reviewed for patient characteristics and medication type and doses. Primary outcomes included serious adverse events and retained gastric products based on patient records, procedure reports, and procedural videos. RESULTS Fifty-seven consecutive adults (89.5% women, mean age of 44 ± 9 years, mean BMI of 40.1 ± 8.1 kg/m2, 35.1% with T2DM, and 26.3% with pre-T2DM) underwent ESG without stopping GLP1-RAs, which included semaglutide (45.6%), liraglutide (19.3%), dulaglutide (22.8%), and tirzepatide (12.3%). During intubation, endoscopy, and recovery, there were no instances of retained gastric solids, pulmonary aspiration, gastroesophageal regurgitation, or hypoxia. CONCLUSION A ≥ 24-h pre-endoscopy liquid-only diet with ≥ 12-h pre-endoscopy fast may negate the need for GLP1-RA interruption for routine upper endoscopy in adults with native gastric anatomy.

Abstract
Obesity has become a major public health concern worldwide. Pharmacological interventions with the glucagon-like peptide-1 receptor agonists (GLP-1RAs) have shown promising results in facilitating weight loss and improving metabolic outcomes in individuals with obesity. Quantifying drug effects of GLP-1RAs on energy intake (EI) and body weight (BW) using a QSP modeling approach can further increase the mechanistic understanding of these effects, and support obesity drug development. An extensive literature-based dataset was created, including data from several diet, liraglutide and semaglutide studies and their effects on BW and related parameters. The Hall body composition model was used to quantify and predict effects on EI. The model was extended with (1) a lifestyle change/placebo effect on EI, (2) a weight loss effect on activity for the studies that included weight management support, and (3) a GLP-1R agonistic effect using in vitro potency efficacy information. The estimated reduction in EI of clinically relevant dosages of semaglutide (2.4 mg) and liraglutide (3.0 mg) was 34.5% and 13.0%, respectively. The model adequately described the resulting change in BW over time. At 20 weeks the change in BW was estimated to be -17% for 2.4 mg semaglutide and -8% for 3 mg liraglutide, respectively. External validation showed the model was able to predict the effect of semaglutide on BW in the STEP 1 study. The GLP-1RA body composition model can be used to quantify and predict the effect of novel GLP-1R agonists on BW and changes in underlying processes using early in vitro efficacy information.

Abstract
Despite its considerable and growing burden, there are currently no Food and Drug Administration-approved treatments for metabolic dysfunction-associated steatotic liver disease or its progressive form, metabolic dysfunction-associated steatohepatitis (MASH). Several glucagon-like peptide-1 receptor agonists (GLP-1RAs) and other agents are in various phases of clinical development for use in MASH; an ideal therapy should reduce liver fat content, improve chronic liver disease, help mitigate metabolic comorbidities and decrease all-cause mortality. Because of interconnected disease mechanisms, metabolic dysfunction-associated steatotic liver disease/MASH often coexists with type 2 diabetes (T2D), obesity and cardiovascular disease. Various GLP-1RAs are Food and Drug Administration-approved for use in T2D, and two, liraglutide and semaglutide, are approved for overweight and obesity. GLP-1RAs decrease glucose levels and body weight and improve cardiovascular outcomes in people with T2D who are at high risk of cardiovascular disease. In addition, GLP-1RAs have been reported to reduce liver fat content and liver enzymes, reduce oxidative stress and improve hepatic de novo lipogenesis and the histopathology of MASH. Weight loss may contribute to these effects; however, the exact mechanisms are unknown. Adverse events that are commonly associated with GLP-1RAs include vomiting, nausea and diarrhoea. There is a lack of evidence from meta-analyses regarding the increased risk of acute pancreatitis and various forms of cancer with GLP-1RAs. Large-scale, phase 3 trials, which will provide definitive data on GLP-1RAs and other potential therapies in MASH, are ongoing. Given the spectrum of modalities under investigation, it is hoped that these trials will support the identification of pharmacotherapies that provide clinical benefit for patients with MASH.

Abstract
INTRODUCTION Glucagon-like peptide-1 receptor agonists (GLP-1RAs) prescribed for weight loss and type 2 diabetes mellitus (T2DM) can delay gastric emptying, but risk factors and impact on procedure outcomes remain unclear. METHODS We compared frequency of gastric residue on upper endoscopy in patients on a GLP-1RA and propensity score-matched controls in this retrospective case-control study of consecutive patients undergoing endoscopic procedures over a 3.5-year period. GLP-1RAs were not held before endoscopy. The gastric residue presence was assessed by reviewing endoscopy reports and images. Predictors and consequences of gastric residue with GLP-1RA were determined. RESULTS In 306 GLP-1RA users compared with matched controls, rates of gastric residue were significantly higher with GLP-1RA use (14% vs 4%, P < 0.01), especially in patients with T2DM (14% vs 4%, P < 0.01), with insulin dependence (17% vs 5%, P < 0.01) and T2DM complications (15% vs 2%, P < 0.01). Lower gastric residue rates were noted after prolonged fasting and clear liquids for concurrent colonoscopy (2% vs 11%, P < 0.01) and in patients with afternoon procedures (4% vs 11%, P < 0.01). While 22% with gastric residue required intubation and 25% had early procedure termination, no procedural complications or aspiration were recorded. DISCUSSION GLP-1RA use is associated with increased gastric residue on upper endoscopy, particularly in patients with T2DM, surpassing the impact of opiates alone. Risk is highest in the presence of T2DM complications while prolonged fasting and a clear-liquid diet are protective. This increased risk of gastric residue does not appear to translate to an increased risk of procedural complications.

Abstract
Semaglutide is the second marketed glucagon-like peptide 1 receptor agonist that can be used safely and efficiently in non-diabetic people with excess weight, providing a new milestone in the pharmacological treatment of obesity. This narrative review aims to describe the clinical actions of this new drug in weight management in non-diabetic patients along with possible side-effects and dropout reasons. To accomplish this, the PubMed database was searched to retrieve the most relevant clinical studies published to date on this topic, using the following keywords "semaglutide and obesity". Currently, semaglutide is on the market in two formulations, the once-weekly subcutaneous (s.c.) semaglutide and once-daily oral semaglutide. Data in the literature on the anti-obesity action of semaglutide are available for both routes of administration of the drug, with a prevalence of studies using the s.c. one. However, given its dosage, oral semaglutide may provide greater attractiveness and better treatment adherence, but further research is needed in this field.

Abstract
PURPOSE OF REVIEW To summarize the mechanism of action, clinical outcomes, and perioperative implications of glucagon-like peptide-1 receptor agonists (GLP-1-RAs). Specifically, this review focuses on the available literature surrounding complications (primarily, bronchoaspiration) and current recommendations, as well as knowledge gaps and future research directions on the perioperative management of GLP-1-RAs. RECENT FINDINGS GLP-1-RAs are known to delay gastric emptying. Accordingly, recent case reports and retrospective observational studies, while anecdotal, suggest that the perioperative use of GLP-1-RAs may increase the risk of bronchoaspiration despite fasting intervals that comply with (and often exceed) current guidelines. As a result, guidelines and safety bulletins have been published by several Anesthesiology Societies. SUMMARY While rapidly emerging evidence suggests that perioperative GLP-1-RAs use is associated with delayed gastric emptying and increased risk of bronchoaspiration (particularly in patients undergoing general anesthesia and/or deep sedation), high-quality studies are needed to provide definitive answers with respect to the safety and duration of preoperative drug cessation, and optimal fasting intervals according to the specific GLP-1-RA agent, the dose/duration of administration, and patient-specific factors. Meanwhile, clinicians must be aware of the potential risks associated with the perioperative use of GLP-1-RAs and follow the recommendations put forth by their respective Anesthesiology Societies.

Abstract
BACKGROUND To evaluate the efficacy and safety of once-weekly subcutaneous semaglutide treatment in overweight or obese patients without type 2 diabetes. METHODS Randomized clinical trials that assessed the impact of once-weekly semaglutide on body weight and safety outcomes in overweight or obese patients were retrieved from PubMed, EMBASE, and Lilacs up to November 2023. Risk of bias was assessed with RoB 2.0, and certainty of evidence (CoE) with GRADE. A random-effects meta-analysis was conducted. RESULTS Ten publications, with 22.155 patients, were included. Semaglutide decreased relative body weight (MD: -11.80; 95%CI: -13.53 to -10.07; CoE: High), absolute body weight (MD: -11.58; 95%CI: -13.25 to -9.90; CoE: High) and BMI (MD: -4.15; 95%CI: -4.85 to -3.45; CoE: High). Semaglutide also increased the proportion of patients who achieved 5%, 10%, and 15% of weight loss ([weight loss≥5%: RR 2.29, 95% CI: 1.88 to 2.80; CoE: High]; [weight loss≥10%: RR 4.54, 95% CI: 3.45 to 5.98; CoE: High]; [weight loss≥15%: RR 8.29, 95%CI: 5.54 to 12.39; CoE: High]). Semaglutide leads to small risk to adverse events (RR: 1.03; 95%CI: 1 to 1.06; CoE: High), no difference in the serious adverse events (RR: 1.07; 95%CI: 0.70 to 1.62; CoE: Low), but increases in the risk to discontinued treatment (RR: 2.03; 95%CI: 1.87 to 2.20; CoE: High) and gastrointestinal adverse events (RR: 3.26; 95%CI: 1.99 to 5.34; CoE: Moderate). CONCLUSION This up-to-date systematic review highlights that once-weekly semaglutide treatment resulted in clinically important weight loss, becoming a promising adjuvant therapy for obesity.

Abstract
INTRODUCTION Divergent recommendations for periprocedural management of glucagon-like peptide-1 (GLP-1) receptor agonist (GLP-1 RA) medications rely on limited evidence. We performed a systematic review and meta-analysis to provide quantitative measures of gastric emptying relevant to mechanisms of weight loss and to periprocedural management of GLP-1 RA. We hypothesized that the magnitude of gastric emptying delay would be low and of limited clinical significance to procedural sedation risks. METHODS A protocolized search identified studies on GLP-1 RA that quantified gastric emptying measures. Pooled estimates using random effects were presented as a weighted mean difference with 95% confidence intervals (CIs). Univariate meta-regression was performed to assess the influence of GLP-1 RA type, short-acting vs long-acting mechanism of action, and duration of treatment on gastric emptying. RESULTS Fifteen studies met the inclusion criteria. Five studies (n = 247) utilized gastric emptying scintigraphy. Mean T 1/2 was 138.4 minutes (95% CI 74.5-202.3) for GLP-1 RA vs 95.0 minutes (95% CI 54.9-135.0) for placebo, with a pooled mean difference of 36.0 minutes (95% CI 17.0-55.0, P < 0.01, I2 = 79.4%). Ten studies (n = 411) utilized the acetaminophen absorption test, with no significant delay in gastric emptying measured by T max , area under the curve (AUC) 4hr , and AUC 5hr with GLP-1 RA ( P > 0.05). On meta-regression, the type of GLP-1 RA, mechanism of action, and treatment duration did not impact gastric emptying ( P > 0.05). DISCUSSION While a gastric emptying delay of ∼36 minutes is quantifiable on GLP-1 RA medications, it is of limited magnitude relative to standard periprocedural fasting periods. There were no substantial differences in gastric emptying on modalities reflective of liquid emptying (acetaminophen absorption test), particularly at time points relevant to periprocedural care.

Abstract
BACKGROUND & AIMS Glucagon-like peptide-1-receptor agonists (GLP1-RAs) have been associated with greater retention of gastric contents, however, there is minimal controlled, population-based data evaluating the potential adverse effects of GLP1-RA in the periprocedural setting. We aimed to determine if there is increased risk of aspiration and aspiration-related complications after upper endoscopy in patients using GLP1-RAs. METHODS We used a nationwide commercial administrative claims database to conduct a retrospective cohort study of patients aged 18 to 64 with type 2 diabetes who underwent outpatient upper endoscopy from 2005 to 2021. We identified 6,806,046 unique upper endoscopy procedures. We compared claims for aspiration and associated pulmonary adverse events in the 14 days after upper endoscopy between users of GLP1-RAs, dipeptidyl peptidase 4 inhibitors (DPP4is), and chronic opioids. We adjusted for age, sex, Charlson Comorbidity score, underlying respiratory disease, and gastroparesis. RESULTS We found that pulmonary adverse events after upper endoscopy are rare, ranging from 6 to 25 events per 10,000 procedures. When comparing GLP1-RAs with DPP4i, crude relative risks of aspiration (0.67; 95% CI, 0.25-1.75), aspiration pneumonia (0.95; 95% CI, 0.40-2.29), pneumonia (1.07; 95% CI, 0.62-1.86), or respiratory failure (0.75; 95% CI, 0.38-1.48) were not higher in patients prescribed a GLP1-RA. When comparing GLP1-RAs with opioids, crude relative risks were 0.42 (95% CI, 0.15-1.16) for aspiration, 0.60 (95% CI, 0.24-1.52) for aspiration pneumonia, 0.30 (95% CI, 0.19-0.49) for pneumonia, and 0.24 (95% CI, 0.13-0.45) for respiratory failure. These results were consistent across several sensitivity analyses. CONCLUSIONS GLP1-RA use is not associated with an increased risk of pulmonary complications after upper endoscopy compared with DPP4i use in patients with type 2 diabetes.

Abstract
BACKGROUND Obesity is one of the critical public health problems in our society. It leads to various health conditions, such as type 2 diabetes mellitus, cardiovascular disease, hypertension, dyslipidaemia, and non-alcoholic fatty liver disease. With the rising incidence of obesity, there is a growing demand for new therapies which can effectively manage body weight and improve health. CURRENT EVIDENCE Currently under development, multi-receptor agonist drugs may offer a promising solution to meet this unmet medical need. Retatrutide is a novel triple receptor agonist peptide that targets the glucagon receptor (GCGR), glucose-dependent insulinotropic polypeptide receptor (GIPR), and glucagon-like peptide-1 receptor (GLP-1R). This novel drug has the potential to treat metabolic abnormalities associated with obesity as well as diseases resulting from it due to its distinct mechanism of action. The Phase III trial of this pipeline drug for treating type 2 diabetes mellitus, non-alcoholic fatty liver disease, and obesity started on August 28, 2023. The results of a Phase II clinical trial have demonstrated significant weight reduction in overweight and obese adults. Specifically, the trial reported an average weight loss of 17.5% and 24.4% at 24 and 48 weeks, respectively. CONCLUSIONS These findings hold promise for the development of effective weight loss interventions in this population group. There is a need for more phase III studies to provide sufficient clinical evidence for the effectiveness of retatrutide, as current evidence is limited to phase II studies and has yet to prove its worth in a larger population. Here, we aimed to provide an overview of retatrutide's safety and effectiveness in treating obesity.

Obes Surg 2024; 34:1618-1629. [PMID: 38502520 DOI: 10.1007/s11695-024-07158-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Revised: 03/05/2024] [Accepted: 03/06/2024] [Indexed: 03/21/2024]
Abstract
PURPOSE Sleeve gastrectomy (SG) is a commonly performed metabolic-bariatric surgery, but its effectiveness is variable and difficult to predict. Our study aimed to compare control of eating (CoE) attributes pre- and post-SG depending on the achievement of optimal weight loss target at 1 year post-SG. MATERIALS AND METHODS A prospective longitudinal cohort study using the CoE Questionnaire, pre-SG, and postoperatively at 3, 6, and 12 months was conducted. Total weight loss (TWL) ≥ 25% at 12 months post-SG was set as an optimal weight loss target. RESULTS Forty-one patients (80.5% females, mean age 41.7 ± 10.6) were included. Sex, age, baseline weight, BMI, and smoking status were all comparable. At 3 months post-SG, "difficulty to control eating" score became significantly different between ≥ 25%TWL and < 25%TWL groups (7 [0-50] vs. 17 [5-63], p = 0.042). At 6 months, it was followed by "feeling of fullness," "frequency of food cravings," and "difficulty to resist cravings" demonstrating significant differences between ≥ 25%TWL and < 25%TWL groups. At 12 months, significant differences between groups were observed in "feeling hungry," "difficulty to resist cravings," "eating in response to cravings," and difficulty to control eating scores. CONCLUSION Individuals with obesity who achieved a target of ≥ 25%TWL at 1 year post-SG have an early improvement in overall eating control at 3 months that steadily persists at 6 and 12 months. Improvements in other aspects tend to follow later, at 6 and 12 months. These findings may assist in identifying individuals with inadequate response to help attain optimal weight loss targets and developing a prognostic model to identify predictors of successful weight loss.

Abstract
DESCRIPTION The purpose of this Clinical Practice Update (CPU) Expert Review is to provide clinicians with guidance on best practices for performing a high-quality upper endoscopic exam. METHODS The best practice advice statements presented herein were developed from a combination of available evidence from published literature, guidelines, and consensus-based expert opinion. No formal rating of the strength or quality of the evidence was carried out, which aligns with standard processes for American Gastroenterological Association (AGA) Institute CPUs. These statements are meant to provide practical, timely advice to clinicians practicing in the United States. This Expert Review was commissioned and approved by the American Gastroenterological Association (AGA) Institute Clinical Practice Updates (CPU) Committee and the AGA Governing Board to provide timely guidance on a topic of high clinical importance to the AGA membership, and underwent internal peer review by the CPU Committee and external peer review through standard procedures of Clinical Gastroenterology & Hepatology. BEST PRACTICE ADVICE 1: Endoscopists should ensure that upper endoscopy is being performed for an appropriate indication and that informed consent clearly explaining the risks, benefits, alternatives, sedation plan, and potential diagnostic and therapeutic interventions is obtained. These elements should be documented by the endoscopist before the procedure. BEST PRACTICE ADVICE 2: Endoscopists should ensure that adequate visualization of the upper gastrointestinal mucosa, using mucosal cleansing and insufflation as necessary, is achieved and documented. BEST PRACTICE ADVICE 3: A high-definition white-light endoscopy system should be used for upper endoscopy instead of a standard-definition white-light endoscopy system whenever possible. The endoscope used for the procedure should be documented in the procedure note. BEST PRACTICE ADVICE 4: Image enhancement technologies should be used during the upper endoscopic examination to improve the diagnostic yield for preneoplasia and neoplasia. Suspicious areas should be clearly described, photodocumented, and biopsied separately. BEST PRACTICE ADVICE 5: Endoscopists should spend sufficient time carefully inspecting the foregut mucosa in an anterograde and retroflexed view to improve the detection and characterization of abnormalities. BEST PRACTICE ADVICE 6: Endoscopists should document any abnormalities noted on upper endoscopy using established classifications and standard terminology whenever possible. BEST PRACTICE ADVICE 7: Endoscopists should perform biopsies for the evaluation and management of foregut conditions using standardized biopsy protocols. BEST PRACTICE ADVICE 8: Endoscopists should provide patients with management recommendations based on the specific endoscopic findings (eg, peptic ulcer disease, erosive esophagitis), and this should be documented in the medical record. If recommendations are contingent upon histopathology results (eg, H pylori infection, Barrett's esophagus), then endoscopists should document that appropriate guidance will be provided after results are available. BEST PRACTICE ADVICE 9: Endoscopists should document whether subsequent surveillance endoscopy is indicated and, if so, provide appropriate surveillance intervals. If the determination of surveillance is contingent on histopathology results, then endoscopists should document that surveillance intervals will be suggested after results are available.

Food Cravings and Obesity in Women with Polycystic Ovary Syndrome: Pathophysiological and Therapeutic Considerations. Nutrients 2024; 16:1049.

Abstract
Polycystic ovary syndrome (PCOS), the most common endocrine disorder in women of reproductive age, constitutes a metabolic disorder frequently associated with obesity and insulin resistance (IR). Furthermore, women with PCOS often suffer from excessive anxiety and depression, elicited by low self-esteem due to obesity, acne, and hirsutism. These mood disorders are commonly associated with food cravings and binge eating. Hypothalamic signaling regulates appetite and satiety, deteriorating excessive food consumption. However, the hypothalamic function is incapable of compensating for surplus food in women with PCOS, leading to the aggravation of obesity and a vicious circle. Hyperandrogenism, IR, the reduced secretion of cholecystokinin postprandially, and leptin resistance defined by leptin receptors' knockout in the hypothalamus have been implicated in the pathogenesis of hypothalamic dysfunction and appetite dysregulation. Diet modifications, exercise, and psychological and medical interventions have been applied to alleviate food disorders, interrupting the vicious circle. Cognitive-behavioral intervention seems to be the mainstay of treatment, while the role of medical agents, such as GLP-1 analogs and naltrexone/bupropion, has emerged.

Abstract
The objective is to review the newer pharmacological interventions for obesity, specifically single, dual and triple incretin receptor agonists that are either available or in the pipeline for treatment of obesity. The three incretin receptor targets are glucagon like peptide-1 (GLP-1), glucose-dependent insulinotropic peptide (GIP) and glucagon. There are several approved single or dual incretin agonists which can be administered subcutaneously daily (e.g., liraglutide) or weekly (e.g., semaglutide, dulaglutide, and exenatide QW), and other experimental dual or triple incretin agonists. Analogues of amylin, peptide YY and oxyntomodulin, as well as the combination of a GLP1R agonist and GIPR antagonist also are in development. Oral semaglutide (administered daily) is approved for type 2 diabetes mellitus and is on track for regulatory review for obesity. The review includes specifically perspectives on the effects of these mechanisms and pharmacological agents on gastric emptying, which contribute to satiation and weight loss, in addition to the established evidence on effects on central mechanisms controlling appetite. In the future, it is anticipated that small molecule GLP-1 receptor agonists (e.g., oral danuglipron) will be developed for treating obesity. These pharmacological agents are having significant impact on glycaemic control and obesity and on their co-morbidities.

Abstract
Prescriptions and use of glucagon-like peptide-1 (GLP-1) receptor agonists are increasing dramatically, as indications are expanding from the treatment of diabetes mellitus to weight loss for people with obesity. As GLP-1 receptor agonists delay gastric emptying, perioperative healthcare practitioners could be concerned about an increased risk for pulmonary aspiration during general anaesthesia. We summarise relevant medical literature and provide evidence-based recommendations for perioperative care for people taking GLP-1 receptor agonists. GLP-1 receptor agonists delay gastric emptying; however, ongoing treatment attenuates this effect. The risk of aspiration during general anaesthesia is unknown. However, we advise caution in patients who recently commenced on GLP-1 receptor agonists. After over 12 weeks of treatment, standard fasting times likely suffice to manage the risk of pulmonary aspiration for most otherwise low-risk patients.

Abstract
Glucagon-like peptide receptor (GLP-1R) agonists (e.g., semaglutide, liraglutide, etc.) are efficient treatment options for people with type 2 diabetes and obesity. The manufacturing method to produce semaglutide, a blockbuster GLP-1 drug on the market, involves multistep synthesis. The large peptide has a hydrophobic fatty acid side chain that makes it sparingly soluble, and its handling, purification, and large-scale production difficult. The growing demand for semaglutide that the manufacturer is not capable of addressing immediately triggered a worldwide shortage. Thus, we have developed a potential alternative analogue to semaglutide by replacing the hydrophobic fatty acid with a hydrophilic human complex-type biantennary oligosaccharide. Our novel glycoGLP-1 analogue was isolated in an ∼10-fold higher yield compared with semaglutide. Importantly, our glycoGLP-1 analogue possessed a similar GLP-1R activation potency to semaglutide and was biologically active in vivo in reducing glucose levels to a similar degree as semaglutide.

Abstract
BACKGROUND Glucagon-like peptide-1 (GLP-1) analogs are approved for the treatment of obesity in adults and adolescents. Reports have emerged that the weight loss effect of these medications may be related to changes in food preferences and ingestive behaviors following the treatment. Understanding the mechanisms which impact ingestive behavior could expand opportunities to develop more refined and personalized treatment options for obesity. METHODS Recent studies investigating the relationship between GLP-1 analogs and ingestive behaviors were retrieved from PubMed using the search terms: "obesity," "food preference," "taste," "ingestive behavior," "weight loss medication," "anti-obesity medication," "GLP-1 analog," "tirzepatide," "liraglutide," "semaglutide." Measurement tools were studied to compare variables used to assess food intake behavior. The main outcomes from each study were analyzed to evaluate the current standing and future directions of appetitive, ingestive, and consummatory behaviors and their association with GLP-1 analogs. RESULTS Thus far, studies have primarily explored the weight loss phase and report decreased short-term appetite and food intake upon treatment. However, research during the weight maintenance phase and objective measurements of food intake are notably sparse. Additionally, verbal reports have been primarily used to examine food intake, which can be susceptible to subjectivity. CONCLUSIONS Elucidating the relationship between GLP-1 analogs and ingestive behavior could reveal additional parameters which contribute to their anti-obesity effects. To better understand these mechanisms, it is imperative to consider objective measurements of food intake in future studies. Several measurement tools have been adapted to measure variables of food behavior in humans, and each must be carefully considered with their strengths and limitations to develop optimal investigations.

Abstract
The hypothalamic neuropeptides linked to appetite and satiety were investigated in obese mice treated with cotadutide (a dual receptor agonist of glucagon-like peptide 1 (GLP-1R)/Glucagon (GCGR)). Twelve-week-old male C57BL/6 mice were fed a control diet (C group, n = 20) or a high-fat diet (HF group, n = 20) for ten weeks. Each group was further divided, adding cotadutide treatment and forming groups C, CC, HF, and HFC for four additional weeks. The hypothalamic arcuate neurons were labeled by immunofluorescence, and protein expressions (Western blotting) for neuropeptide Y (NPY), proopiomelanocortin (POMC), agouti-related protein (AgRP), and cocaine- and amphetamine-regulated transcript (CART). Cotadutide enhanced POMC and CART neuropeptides and depressed NPY and AGRP neuropeptides. In addition, gene expressions (RT-qPCR) determined that Lepr (leptin receptor) and Calcr (calcitonin receptor) were diminished in HF compared to C but enhanced in CC compared to C and HFC compared to HF. Besides, Socs3 (suppressor of cytokine signaling 3) was decreased in HFC compared to HF, while Sst (somatostatin) was higher in HFC compared to HF; Tac1 (tachykinin 1) and Mc4r (melanocortin-4-receptor) were lower in HF compared to C but increased in HFC compared to HF. Also, Glp1r and Gcgr were higher in HFC compared to HF. In conclusion, the findings are compelling, demonstrating the effects of cotadutide on hypothalamic neuropeptides and hormone receptors of obese mice. Cotadutide modulates energy balance through the gut-brain axis and its associated signaling pathways. The study provides insights into the mechanisms underlying cotadutide's anti-obesity effects and its possible implications for obesity treatment.

Abstract
Semaglutide, a glucagon-like peptide-1 (GLP-1) analog, has various effects on the gastrointestinal tract. In patients undergoing anesthesia delayed gastric emptying time can have sequelae if not identified preoperatively. Modalities include thorough history regarding the last dose administration of a GLP-1 analog and ultrasound of gastric contents before induction of anesthesia. We present a case in which gastric ultrasound identified a patient at increased risk for aspiration on induction and allowed for appropriate alterations in the anesthetic plan.

Abstract
Humans are becoming less active in the current age of technological advancement, which leads to poor health. Many factors, including unregulated diet, lack of exercise, environmental pollution and genetic factors are contributing to an increase in overweight. Obesity is a chronic condition that disturbs the physical health of a person, resulting in various other complications including cardiac, respiratory, and psychosocial issues. According to WHO, the current trend of obesity has shown a sharp increase in recent years. Methods ranging from as simple as regulating the diet to as complex as surgery are available. There are many approved drugs to treat the obesity majority of them works as suppressing the appetite and making the patient satisfy. Some of other agents works by insulinotropic activity. However, these agents need to be taken for longer period of time thus are associated with significant adverse drug reactions. Thus, the motive of this study is to understand obesity and the various methods available to manage it using the recent pharmacological and non-pharmacological approaches.

Efficacy and safety of semaglutide 2.4 mg for weight loss in overweight or obese adults without diabetes: An updated systematic review and meta-analysis including the 2-year STEP 5 trial. Diabetes Obes Metab 2024; 26:911-923. [PMID: 38016699 DOI: 10.1111/dom.15386] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 10/23/2023] [Accepted: 11/12/2023] [Indexed: 11/30/2023]
Abstract
AIM To explore the safety and efficacy of subcutaneous semaglutide 2.4 mg, administered once a week in non-diabetic overweight or obese individuals. METHODS A thorough search was performed of various databases including PubMed, Embase, the Cochrane Library, Web of Science, clinicaltrials.gov, CNKI and Wanfang from their inception up to April 11, 2023. Our aim was to identify randomized controlled trials (RCTs) that compared the efficacy of semaglutide administered once weekly with placebo in overweight or obese adults. Through a review of the literature, data were extracted from relevant studies and assessed for quality, and a meta-analysis was conducted using RevMan 5.4.1 software. RESULTS Six RCTs comprising 3962 overweight or obese individuals were identified. The findings indicated that, in comparison to the placebo group, semaglutide caused a significant and sustainable reduction in the percentage of body weight (BW; mean difference [MD]: -11.80% [95% confidence interval {CI} -12.93, -10.68]; P < 0.00001) as well as a decrease in absolute BW (MD: -12.2 kg [95% CI -13.3, -11.1]; P < 0.00001), body mass index (MD: -4.5 kg/m2 [95% CI -4.9, -4.1]; P < 0.00001) and waist circumference (MD:-9.4 cm [95% CI -10.1, -8.8]; P < 0.00001). Moreover, it achieved a higher proportion of patients who experienced weight loss exceeding 5%, 10%, 15% and 20%. Furthermore, semaglutide showed significant efficacy in controlling blood pressure, blood sugar levels, C-reactive protein levels, and lipid profiles. In terms of safety, the most common adverse effects following semaglutide treatment were gastrointestinal adverse reactions (risk ratio: 1.49 [95% CI 1.38, 1.60]; P < 0.00001), which were generally mild to moderate in severity and temporary. CONCLUSION In overweight or obese non-diabetic individuals, semaglutide had a remarkable and sustained weight loss effect that was well tolerated and safe.

Abstract
AIM To evaluate the effect of noiiglutide as an adjunct to lifestyle intervention on the reduction in body weight and tolerability in obese Chinese adults without diabetes. MATERIALS AND METHODS In this 24-week, randomized, double-blind, placebo-controlled phase 2 trial, 254 obese adults with a body mass index of 28.0-40.0 kg/m2 and without diabetes were enrolled. Participants were initially randomized in a 1:1:1 ratio to one of three dose levels: 0.12, 0.24, or 0.36 mg of the study treatment. Within each dose level, participants were further randomized in a 3:1 ratio to receive either subcutaneous injection of noiiglutide or a matching placebo. The primary endpoint was the change in body weight from baseline to week 24. RESULTS Across all noiiglutide dosage levels, least squares mean reductions in body weight from baseline to week 24 ranged from 8.03 to 8.50 kg, compared with 3.65 kg in the placebo group (all p-values <.0001). In the noiiglutide groups (0.12, 0.24, 0.36 mg/day), a significantly higher proportion of participants achieved a weight loss ≥5% (68.8%, 60.0%, 73.0%) and ≥10% (37.5%, 36.9%, 39.7%), compared with the pooled placebo group (≥5%: 29.0%; ≥10%: 8.1%). Gastrointestinal adverse events, such as nausea, diarrhoea and vomiting, were more common in all noiiglutide groups (15.4%-30.2%, 18.8%-22.2%, 15.6%-18.5%) than in the pooled placebo group (8.1%, 6.5%, 0%). CONCLUSIONS In obese Chinese adults without diabetes, once-daily subcutaneous noiiglutide significantly reduced body week at week 24 compared with placebo, and had a manageable safety profile, primarily involving gastrointestinal disorders.

Abstract
Non alcoholic fatty disease (NAFLD) is the most common chronic liver disease that is managed in the liver departments. It seems that the prevalence of the disease is rising worldwide and as it has the same pathogenetic pathways with metabolic syndrome, treatments that target components of the metabolic syndrome seem promising for the therapy of NAFLD as well. In this review we discuss the evolving role of semaglutide, which is a glucagon-like peptide-1 receptor agonist (GLP-1 RA) that has been already approved for the treatment of type II diabetes mellitus (T2DM) and obesity.

Abstract
INTRODUCTION Food addiction (FA) is highly prevalent among people with obesity (PwO) and may constitute a key factor in weight loss failure or weight regain. GLP-1 analogues have been shown to act on the mesolimbic system, which is related to hedonic overeating and substance abuse. We aimed to study the effects of low doses of semaglutide on FA symptomatology and to evaluate whether the presence of FA have a negative impact on weight loss despite treatment with semaglutide. METHODS One hundred and thirteen PwO (45.5 ± 10.2 years) were evaluated anthropometrically baseline and after four months of treatment with semaglutide. PwO were evaluated for the presence of FA by completing The Spanish version of the Yale Food Addiction Scale 2.0 questionnaire (YFAS 2.0). RESULTS Baseline BMI and fat mass (%) were greater among PwO with FA (35.8 ± 4.5 vs 33 ± 3.9 kg/m2and 44.2 ± 6.5 vs 40.1 ± 7.9%; p = .01). After four months of treatment with semaglutide, the prevalence of FA diminished from 57.5% to 4.2% (p < .001). The percentage of weight loss (6.9 ± 12.7 vs 5.3 ± 4.6%; p = .4) and the proportion of fat mass loss (2 ± 9 vs 1.6 ± 3.1%; p = .7) were comparable between PwO with and without FA. No differences regarding side effects and treatment discontinuations were seen between the two groups. CONCLUSION Semaglutide is an effective tool for the amelioration of FA symptomatology among PwO. Despite PwO with FA had greater basal BMI and fat mass, semaglutide showed similar results compared to PwO without FA in terms of weight and fat mass loss at short term.

Abstract
Obesity is a chronic disease associated with serious complications and increased mortality. Weight loss (WL) through lifestyle changes results in modest WL long-term possibly due to compensatory biological adaptations (increased appetite and reduced energy expenditure) promoting weight gain. Bariatric surgery was until recently the only intervention that consistently resulted in ≥ 15% WL and maintenance. Our better understanding of the endocrine regulation of appetite has led to the development of new medications over the last decade for the treatment of obesity with main target the reduction of appetite. The efficacy of semaglutide 2.4 mg/week-the latest glucagon-like peptide-1 (GLP-1) receptor analogue-on WL for people with obesity suggests that we are entering a new era in obesity pharmacotherapy where ≥15% WL is feasible. Moreover, the WL achieved with the dual agonist tirzepatide (GLP-1/glucose-dependent insulinotropic polypeptide) for people with type 2 diabetes and most recently also obesity, indicate that combining the GLP-1 with other gut hormones may lead to additional WL compared with GLP-1 receptor analogues alone and in the future, multi-agonist molecules may offer the potential to bridge further the efficacy gap between bariatric surgery and the currently available pharmacotherapies.
