To promote use of lifestyle, pharmacologic, and surgical weight management options for adults with body mass index (BMI) ≥35 kg/m2 and type 2 diabetes (T2D), this project implements and evaluates a weight loss clinical decision support (WL-CDS) intervention that provides patient-specific estimates of the risks and benefits of evidence-based obesity management options to primary care clinicians (PCCs) and patients at primary care clinical encounters.

We randomize 38 primary care clinics to either (a) usual care (UC), or (b) the WL- CDS intervention that provides patients and PCCs recommendations for lifestyle changes and patient-specific obesity management options and estimates of benefits and risks of weight loss medications, or metabolic bariatric surgery (MBS) when indicated.

Outcomes assessed at 18-months after a patient-specific index date are (a) referral of eligible patients for MBS evaluation; (b) initiation or active management of FDA-approved medications for weight loss; and (c) weight trajectory. Outcomes measured within 1 month of index date are patient-reported (d) shared decision making about weight loss options, and (e) intention to engage in weight loss.

This study will deepen our understanding of how patients and PCCs use WL-CDS generated information to inform selection of obesity care options for adults with T2D and BMI ≥35 kg/m2.

This meta-analysis aimed to evaluate the effectiveness of Roux-en-Y gastric bypass (RYGB) in people living with type 2 diabetes mellitus (T2DM). A comprehensive search was conducted in the PubMed database up to January 2024. A random-effects model was used to calculate the pooled standard mean differences (SMDs) and odds ratios (ORs). Ten studies were included in our review. The RYGB group demonstrated significantly better outcomes compared to the non-surgical group in multiple measures. These included higher triple criteria compliance rates (OR 9.04, 95% CI 3.22-25.36), complete T2DM remission (OR 15.37, 95% CI 4.42-53.41), and partial T2DM remission (OR 11.49, 95% CI 3.57-37.03). Additionally, improvements were observed in glycated hemoglobin A1c (HbA1c) levels (SMD - 1.41, 95% CI - 2.22 to - 0.61), with HbA1c < 6.0% (OR 8.54, 95% CI 3.38-21.62) and HbA1c < 7.0% (OR 5.62, 95% CI 3.20-9.86). Fasting blood glucose (FBG) levels also showed improvement (SMD - 0.43, 95% CI - 0.71 to - 0.14), with a higher proportion achieving FBG < 100 mg/dl (OR 11.83, 95% CI 4.75-29.43). Other notable outcomes included significant percentage of total weight loss (%TWL: SMD 1.88, 95% CI 1.39-2.37), reductions in body mass index (BMI: SMD - 2.28, 95% CI - 3.52 to - 1.04), and improvements in lipid profiles, including low-density lipoprotein (LDL) levels (SMD - 1.01, 95% CI - 1.91 to - 0.11) and LDL < 2.59 mmol/L (OR 3.65, 95% CI 1.94-6.87). In addition, high-density lipoprotein (HDL) levels increased (SMD 1.30, 95% CI 0.55-2.05), while triglycerides (SMD - 1.11, 95% CI - 1.70 to - 0.52), systolic blood pressure (SBP: SMD - 0.38, 95% CI - 0.70 to - 0.06), and diastolic blood pressure (DBP: SMD - 0.41, 95% CI - 0.63 to - 0.18) decreased. A greater proportion of patients in the RYGB group achieved SBP < 130 mmHg (OR 3.15, 95% CI 1.61-6.13). Moreover, reductions were noted in insulin use (OR 0.25, 95% CI 0.14-0.46), diabetes medication use (SMD - 1.95, 95% CI - 3.32 to - 0.57), and peripheral neuropathy (OR 0.13, 95% CI 0.02-0.79). However, no significant differences were observed in hypertension medication use or retinopathy between the two groups. RYGB was found to be effective in improving glycemic control, promoting weight loss, enhancing lipid profiles, and managing blood pressure. It also significantly reduced the need for postoperative diabetes medications and the incidence of diabetic peripheral neuropathy in people living with T2DM.

Obesity is increasingly prevalent and associated with higher morbidity and mortality. Bariatric surgery, particularly sleeve gastrectomy, provides durable weight loss and improves obesity-related conditions like type 2 diabetes and cardiovascular disease. Despite its benefits, significant concerns regarding inequities in access to bariatric surgery persist. This study aims to evaluate recent trends in bariatric surgery rates and to investigate patterns of access to bariatric surgery.

A population-based study of age-adjusted bariatric procedure rates in adults in NSW, Australia, was conducted over the financial years 2013/14 to 2021/22. Trends in age-adjusted procedure rates were assessed by demographics and healthcare settings.

In 2021/22, 179.6 bariatric procedures per 100,000 population were performed, an 89.7% increase since 2013/14 (p < 0.001). Laparoscopic sleeve gastrectomy, the most common procedure, increased by 94.1% to 112.6/100,000/year (p < 0.001). Females had 3.6 times higher rates than males (232.3/100,000/year vs 64.9/100,000/year). The greatest increases occurred in younger patients (125.9% in the 18-24 age group; 142.4% in the 25-34 age group, p < 0.001). Private hospital rates were 15.6 times higher than public (132.2/100,000/year vs 8.5/100,000/year) and rose 92.3% (p < 0.001), whilst public hospital rates declined by 17.9% (p = NS). Patients from regional areas had the highest rates (175.7/100,000/year) and largest increase (169.8%; 89.4/100,000/year to 241.8/100,000/year, p < 0.001).

Bariatric surgery rates continue to increase, particularly among females, despite similar obesity prevalence between sexes. Most surgery is conducted in the private sector, suggesting differential access based on financial circumstances. Rates are highest in younger people, although obesity-related comorbidities increase with age. Regional patients undergo surgery at higher rates than rural patients despite greater obesity prevalence with increasing rurality. Efforts to address these disparities are essential to improve equitable access to obesity treatments.

The preoperative glycated hemoglobin (HbA1c) cutoff point for elective surgery in patients with type 2 diabetes mellitus (T2DM) remains unclear, as does its association with postoperative outcomes, especially in patients undergoing bariatric surgery.

We conducted a retrospective cohort study including patients with T2DM and an electronic record of HbA1c within the four months prior to surgery who underwent Roux-en-Y gastric bypass (RYGB) from August 2010 to May 2019. The primary outcome was postoperative hospital length of stay (LOS), and secondary outcomes included need for intensive care, clinical outcomes (pulmonary, cardiovascular, septic), and surgical wound complications. These outcomes were assessed using an HbA1c cutoff value of 7 %. Comparisons were made using the Mann-Whitney U test and a general linear model adjusting the primary outcome for confounders and for differences in baseline characteristics between groups.

A total of 114 individuals were divided into two groups according to HbA1c: ≤7 % (N = 63) or > 7 % (N = 51). No differences were observed between the groups in terms of LOS (4 vs 5 days, p = 0.28) and clinical or operative wound complication rates. Alternative HbA1c cutoff points (7.5 %, 8 %, and 8.5 %) were also evaluated for LOS, with no change in results.

Bariatric surgery should not be postponed in patients with T2DM based on an HbA1c greater than 7 %, as LOS, clinical outcomes and operative wound complication rates are not worse in patients with poorer glucose control based on this criterion.

Metabolic and bariatric surgery (MBS) is an effective intervention to manage diabetes and obesity. The population-based incidence of MBS is unknown.

To estimate the incidence of MBS among US adults with obesity by diabetes status and selected sociodemographic characteristics.

This cross-sectional study used data from the 2016-2020 Nationwide Inpatient Sample and Nationwide Ambulatory Surgery Sample to capture MBS procedures. The National Health Interview Survey was used to establish the denominator for incidence calculations. Participants included US non-pregnant adults aged ≥18 years with obesity. The main outcome was incident MBS without previous MBS, defined by International Classification of Diseases, Tenth Revision Procedure Codes, Diagnosis Related Group system codes, and Current Procedural Terminology codes. Adjusted incidence and annual percentage change (2016-2019) were estimated using logistic regression.

Among US adults with obesity, over 900 000 MBS procedures were performed in inpatient and hospital-owned ambulatory surgical centers in the USA during 2016-2020. The age- and sex-adjusted incidence of MBS per 1000 adults was 5.9 (95% CI 5.4 to 6.4) for adults with diabetes and 2.0 (95% CI 1.9 to 2.1) for adults without diabetes. MBS incidence was significantly higher for women and adults with class III obesity regardless of diabetes status. The highest incidence of MBS occurred in the Northeast region. Sleeve gastrectomy was the most common MBS surgical approach.

Incident MBS procedures were nearly threefold higher among adults with obesity and diabetes than those with obesity but without diabetes. Continued monitoring of the trends of MBS and other treatment modalities can inform our understanding of treatment accessibility to guide prevention efforts aimed at reducing obesity and diabetes.

There is a paucity of literature on the impact for bariatric surgery on the progression from prediabetes (PDM) to type II diabetes mellitus (T2DM).

To evaluate the progression from PDM to T2DM in bariatric surgery compared with a nonsurgical cohort.

Single academic institution, Center of Bariatric Excellence.

This retrospective study of patients with morbid obesity with patients with PDM who underwent Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) between 2001 and 2022. Nonsurgical controls from a primary care cohort were directly matched by hemoglobin A1c, age, sex, and body mass index. DM was defined as a clinical diagnosis of type II diabetes or hemoglobin A1c ≥6.5%. Kaplan-Meier analysis was used to estimate time until T2DM. Cox regression was used to compare time until T2DM in RYGB versus sleeve gastrectomy and in bariatric surgery versus nonsurgical controls.

A total of 1326 bariatric cases with PDM (n = 1154 RYGB, n = 172 SG) were identified. The cohort was 83% female, mean age = 45.3 years, mean body mass index 46.9 kg/m2, and follow-up was 65% over 15 years. In bariatric cases, PDM progression to T2DM at 5, 10, and 15 years after surgery was 1.8%, 3.3%, and 6.7%, respectively. PDM progression to T2DM was almost 20 times greater in matched nonsurgical controls at 5, 10, and 15 years 31.1%, 51.4%, and 68.7%, respectively (hazard ratio 19.8, 95% confidence interval 13.9-28.4, P < .0001). When stratifying by bariatric surgery type, those with SG were 4 times more likely to progress to T2DM versus RYGB (hazard ratio 4.01, 95% confidence interval 1.71-9.39, P = .0014).

Bariatric surgery significantly decreases the conversion from PDM to T2DM. The impact was significantly greater for RYGB compared with SG.

Opioids are commonly used in general anesthesia for pain management. However, they are linked to significant side effects. Patients undergoing laparoscopic sleeve gastrectomy, particularly those with obesity, are at higher risk of experiencing adverse effects associated with opioids. Therefore, there is a need to explore alternative anesthesia options that do not rely on opioids. This study aims to investigate the efficacy of opioid-free anesthesia (OFA) compared to traditional opioid-based anesthesia (OBA) in patients undergoing laparoscopic sleeve gastrectomy.

This single-center randomized controlled trial included eighty-three patients undergoing laparoscopic sleeve gastrectomy in a tertiary hospital. Patients were randomly assigned to dexmedetomidine and lidocaine infusion (OFA) or remifentanil (OBA). All patients received intra-operative propofol, sevoflurane, a neuromuscular blocking agent, and ketamine. The primary outcome included opioid consumption during the post-anesthesia care unit (PACU). Secondary measures included intraoperative hemodynamic stability, time to extubation, PACU stay duration, opioid consumption during the first 48 h, and anti-emetic requirements. Independent samples t-test or Mann-Whitney U test was used to assess for differences across the two groups.

PACU morphine consumption, total postoperative morphine consumption, anti-emetic requirements up to 48 h after surgery, and pain levels after surgery were not statistically significantly different between OFA and OBA groups. Other variables were not statistically different between the two groups, except for intraoperative anti-hypertensives where more patients in the OFA groups required it.

Opioid-free anesthesia hasn't shown an opioid-sparing effect in patients with obesity undergoing laparoscopic sleeve gastrectomy. Larger multi-center studies are required to fully establish its effectiveness.

Eating behavior encompasses the psychological, physiological, and environmental factors influencing food intake. Dysregulation in eating behavior, such as emotional eating, binge eating, or loss of satiety signals, contributes to excessive caloric intake and weight gain. These behaviors are often linked to hormonal imbalances, stress, or genetic predisposition. Obesity is a chronic, multifactorial disease characterized by excessive body fat accumulation, with a body mass index (BMI) ≥ 30 kg/m2 often used for diagnosis. It is associated with significant morbidity, including type 2 diabetes, cardiovascular disease, and obstructive sleep apnea. Pathophysiological mechanisms underlying obesity include insulin resistance, leptin dysregulation, and altered gut microbiota, which perpetuate metabolic derangements. Lifestyle interventions remain first-line treatment, but sustained weight loss is challenging for many patients. Bariatric surgery is a therapeutic option for individuals with severe obesity (BMI ≥ 40 kg/m2 or ≥35 kg/m2 with comorbidities) who have failed conservative management. Procedures such as Roux-en-Y gastric bypass and sleeve gastrectomy alter gastrointestinal anatomy, promoting weight loss through restriction, malabsorption, and hormonal modulation (e.g., increased GLP-1 secretion). Bariatric surgery improves obesity-related comorbidities and enhances quality of life. However, it requires lifelong medical follow-up to address potential nutritional deficiencies and ensure sustainable outcomes.

The global prevalence of obesity and type 2 diabetes mellitus (T2D) has risen in parallel over recent decades. Most individuals diagnosed with T2D exhibit adiposopathy-related diabetes (ARD), a condition characterized by hyperglycemia accompanied by three core features: increased ectopic and visceral fat deposition, dysregulated adipokine secretion favoring a pro-inflammatory state, and insulin resistance. Despite advancements in precision medicine, international guidelines for T2D continue to prioritize individualized therapeutic approaches focused on glycemic control and complications, and many healthcare providers predominantly maintain a glucocentric strategy. This review advocates for an adipocentric treatment paradigm for most individuals with T2D, emphasizing the importance of prioritizing weight loss and visceral fat reduction as key drivers of therapeutic intensification. By combining lifestyle modifications with pharmacological agents that promote weight loss-including SGLT-2 inhibitors, GLP-1 receptor agonists, or dual GLP-1/GIP receptor agonists-and, when appropriate, metabolic surgery, this approach offers the potential for disease remission in patients with shorter disease duration. For others, it enables superior metabolic control compared to traditional glucose-centered strategies while simultaneously delivering cardiovascular and renal benefits. In conclusion, an adipocentric treatment framework for ARD, which represents the majority of T2D cases, effectively integrates glucocentric and cardio-nephrocentric goals. This approach constitutes the optimal strategy for ARD due to its efficacy in achieving disease remission, improving metabolic control, addressing obesity-related comorbidities, and reducing cardiovascular and renal morbidity and mortality.

Treatment of type 2 diabetes (T2DM) in patients with obesity can be challenging. Metabolic and bariatric surgery (MBS) has shown promising results in improving glycemic control and even achieving remission in T2DM patients with obesity. However, the durability of glycemic improvements in T2DM patients following MBS remains insufficiently studied.

Determine the incidence of durable remission and relapse of T2DM rates 10 years after MBS, characterize the glycemic profile after surgery, and identify factors predicting persistent remission of T2DM.

Retrospective observational study of T2DM patients undergoing MBS between 2010 and 2013. Clinical and analytical assessments were performed preoperatively, at 2- and at 10-years postoperatively. Paired t-tests, Wilcoxon-signed-rank and McNemar tests were used to assess the differences in the metabolic status during the follow-up. Logistic regression models were used to identify predictors of T2DM remission.

Ninety-five patients were included (mean age 48.8 ± 9.1 years, mean HbA1c 7.0 ± 1.5%). Ten years after surgery, the rate of complete T2DM remission was 31%, partial remission was 15%, and late recurrence after initial remission was 24%. Patients with lower HbA1c (OR = 0.50; p = 0.05) and taking fewer antidiabetic drugs (OR = 0.31; p = 0.01) preoperatively were more likely to maintain long-term remission. Ten years post-MBS, patients maintained lower fasting plasma glucose (p < 0.001), HbA1c (p < 0.001), number of antidiabetic drugs (p < 0.001), and insulin use (p < 0.001).

MBS can induce a significant improvement and sustainable remission of T2DM. Early intervention, while patients still have a good glycemic control with a lower number of anti-diabetic drugs, is crucial to achieve long-lasting benefits and a potential "surgical cure" for T2DM.

Bariatric surgery (BS) is an effective intervention for obesity and related metabolic disorders, significantly improving metabolic health and alleviating hormonal imbalances. However, it induces complex endocrine changes that can lead to dysfunctions, impacting the somatotropic, gonadal, thyroid, pancreatic, and adrenal axes. This review highlights the dual effects of BS on the endocrine system. A comprehensive review of peer-reviewed studies using PRISMA guidelines was conducted, focusing on human research evaluating pre and postoperative endocrine parameters. Studies were selected for their relevance and quality in elucidating the endocrine consequences of BS. BS restores growth hormone secretion and improves fertility but may disrupt insulin-like growth factor-1 recovery and sex hormone balance, leading to bone loss and catabolic states. Postprandial insulin hypersecretion can result in hyperinsulinemic hypoglycemia, with impaired counter-regulatory hormone responses. Secondary hyperparathyroidism and reduced bone density highlight additional risks. Changes in thyroid hormone levels have implications for both hypothyroid and euthyroid patients. These findings underscore the interplay between improved metabolic control and potential endocrine dysfunctions. The current evidence predominantly comprises association studies that may not be of quality for safe clinical decision-making, highlighting the need for high-quality research to establish causality and refine therapeutic strategies. Bridging knowledge gaps in the mechanisms underlying these changes is crucial to optimizing BS outcomes. A holistic approach integrating preoperative screening, individualized postoperative care, and targeted therapies is essential to mitigate complications while maximizing benefits.

Obesity is a prevalent metabolic disorder that significantly contributes to insulin resistance (IR), type 2 diabetes (T2DM), and metabolic syndrome. Sleeve gastrectomy has emerged as an effective surgical intervention for obesity, with potential benefits on metabolic health. This study investigates the impact of sleeve gastrectomy on serum insulin levels, IR (HOMA-IR), inflammatory markers, C-peptide, kidney function, and various biochemical parameters in diabetic and non-diabetic patients.

A prospective cohort study was conducted, involving 199 patients over 18 years old who were candidates for sleeve gastrectomy at Luqman Hakim Hospital from 2021 to 2022. Data were collected using standardized questionnaires and anthropometric measurements, and biochemical assessments were performed before surgery and 6 months postoperatively. Statistical analyses included descriptive statistics, t-tests, Mann-Whitney tests, and repeated measures analysis of variances (ANOVA).

The study included 199 patients (84.4% female) with a mean (± standard deviation (SD)) age of 39.79 ± 11.30 years. Significant reductions were observed in weight, BMI, and abdominal circumference across all patient groups. Diabetic patients showed marked improvements in fasting blood sugar, 2-h postprandial blood sugar, and glycosylated hemoglobin levels. Insulin resistance decreased significantly, as did serum insulin and C-peptide levels. Improvements in lipid profiles and inflammatory markers were also noted. Insulin use post-surgery showed a significant inverse relationship with glycemic control improvement.

Sleeve gastrectomy is a safe and effective procedure for obese patients, significantly improving insulin resistance and various obesity-associated diseases within 6 months post-surgery.

To develop Mexico's first methodologically rigorous clinical practice guideline for the management of adult overweight and obesity. The target audiences are interdisciplinary healthcare professionals across healthcare systems who are the first point of contact for patients with obesity in Mexico, patients, and health system decision makers.

A review of recent international obesity clinical practice guidelines and an expert consensus process identified: i) common recommendations appropriate for implementation in Mexico and ii) knowledge gaps requiring the formulation of new recommendations. In all, 20 new recommendations and 20 good practice statements were developed using the GRADE Evidence-to-Decision Framework and expert consensus. Overweight and obesity negatively impact the health and well-being of individuals and populations in Mexico. This guideline aims to establish a new evidence-based, patient-centered, non-stigmatizing, and practical treatment and management framework, based on the fundamental principles of chronic disease prevention and management.

The worldwide prevalence of type 2 diabetes mellitus (T2DM) is increasing in parallel with obesity. One anastomosis gastric bypass (OAGB) is considered effective to treat both T2DM and obesity. The aim of this study was to evaluate the efficacy of OAGB versus sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) for treatment of T2DM, analyzing data exclusively from randomized control trials (RCTs). Α systematic review of published RCTs comparing OAGB versus RYGB or SG (control groups) in T2DM patients regarding diabetes remission and weight loss was performed. Primary endpoints were T2DM remission rate and 1-year and 5-year % weight loss postoperatively. Initial search identified 39 references, of which 8 RCTs were considered eligible for meta-analysis inclusion, comprising 636 patients (311 OAGB, 122 RYGB, 203 SG patients). Main meta-analysis findings were: i) higher 1-year %EWL for OAGB than control group (p = 0.04); ii) higher 5-year %EWL for OAGB than control group (p < 0.01); iii) no difference in 1-year remission rate of T2DM between OAGB and control group (p = 0.14); iv) 28% higher 5-year remission rate of T2DM for OAGB than control group (p < 0.01). OAGB had statistically significant better outcomes compared to RYGB and SG regarding T2DM remission and %EWL at 5 years. Further pathophysiologic studies are needed to indicate the most potent bariatric procedure in patients with T2DM and obesity.

New in this edition are new sections such as obesity, chronic kidney disease and metabolic hepatic steatosis, as well as a 'Don't Do' section in the different pathologies treated. The sections have been updated: epidemiological review, where the current morbidity and mortality of CVD in Spain and its evolution as well as the main risk factors are described; vascular risk (VR) and recommendations for the calculation of CV risk; main risk factors such as arterial hypertension, dyslipidemia and diabetes mellitus, describing the method for their diagnosis, therapeutic objectives and recommendations for lifestyle measures and pharmacological treatment; indications for antiplatelet therapy, and recommendations for screening of atrial fibrillation, and recommendations for management of chronic conditions. The quality of testing and the strength of the recommendation are included in the main recommendations.

Our study aimed to compare the short- and particularly long-term type 2 diabetes mellitus (T2DM) remission prediction abilities of ABCD, individualised metabolic surgery (IMS), DiaRem2, Ad-DiaRem and DiaBetter scoring systems in Turkish adult type 2 diabetic morbidly obese patients who underwent bariatric surgery.

Our study was planned as a retrospective cohort study. A total of 137 patients with T2DM, including 78 sleeve gastrectomy (SG) and 59 Roux-en-Y gastric bypass (RYGB) patients, were included in the 1 st -year evaluation after bariatric surgery, and a total of 115 patients with T2DM, including 64 SG and 51 RYGB patients, were included in the evaluation at the end of the 5 th year.

In the 1 st year after bariatric surgery, area under the ROC curve (AUC) values for diabetes remission scores were 0.863 for Ad-DiaRem, 0.896 for DiaBetter, 0.840 for DiaRem2, 0.727 for ABCD and 0.836 for IMS. At 5 years after bariatric surgery, the AUC values for diabetes remission were 0.834 for Ad-DiaRem, 0.888 for DiaBetter, 0.794 for DiaRem2, 0.730 for ABCD and 0.878 for IMS.

According to our study, the DiaBetter score provided a better AUC value than the other scores both in the short and long term but showed similar predictive performance to Ad-DiaRem in the short term and IMS in the long term. We believe that DiaBetter and Ad-DiaRem scores might be more appropriate for short-term assessment and DiaBetter and IMS scores for long-term remission assessment.

Background/Objectives: Metabolic syndrome, defined by the coexistence of central obesity, dyslipidemia, hypertension, and insulin resistance, is a significant contributor to increased cardiovascular morbidity and mortality in the aging population. We aimed to determine whether age influences the efficacy of LSG in treating obesity-related comorbidities. Methods: A retrospective analysis of lipid profiles, glycemic and clinical parameters was conducted in a group of 786 patients in two age groups (under 50 years old and over 50 years old) who underwent laparoscopic sleeve gastrectomy with follow-ups 1, 3, 6, 12 and 24 months after surgery. Results: There was a significant improvement in lipid metabolism with no significant differences between the two age groups in these parameters throughout the observation period. Furthermore, there was significant weight loss (54.82 kg vs. 54.56 kg) and BMI reductions (47.71 kg/m2 vs. 47.01 kg/m2 to 29.03 kg/m2 vs. 30.73 kg/m2). Total cholesterol decreased from 198 mg/dL to 184.9 mg/dL (<50 years old) and from 206.4 mg/dL to 193 mg/dL (>50 years old). LDL dropped from 136.2 mg/dL to 116.7 mg/dL and from 141.0 mg/dL to 121.0 mg/dL. Mean HbA1c decreased to comparable levels (5.66% vs. 5.53%). Both groups showed similar rates of remission for type 2 diabetes and hypertension. Conclusions: Our findings suggest that LSG is an effective method for treating components of metabolic syndrome regardless of age, supporting its use as a therapeutic tool for older patients.

Type 2 diabetes mellitus is one of the most prevalent health conditions worldwide, affecting millions of individuals and posing significant public health challenges. Understanding the nature of type 2 diabetes, its causes, symptoms and treatments is crucial for managing and preventing its complications. Many different dietary strategies are used by individuals to treat and manage diabetes. This review provides an overview of popular dietary strategies that have evidence for improving long-term glycaemic control or achieving diabetes remission, as well as strategies that may be useful to reduce postprandial hyperglycaemia, which may be of use in the prevention of diabetes, but also as strategies for those already diagnosed but trying to manage their condition better. Recent clinical trials have provided evidence that in people living with type 2 diabetes who also live with overweight or obesity, using a total diet replacement weight loss programme results in significant and substantial weight loss, and as a result, many people can achieve remission from their diabetes. There has been considerable interest in whether similar effects can be achieved without reliance on formula foods, using real diet approaches. Reduced or low-carbohydrate diet approaches hold some promise, with observational or preliminary findings suggesting beneficial effects, but evidence from robust trials or systematic reviews of randomized controlled trials is still lacking. The Mediterranean dietary pattern, low in saturated fat and high in monounsaturated fat, also has some potential, with evidence to suggest some people can lose weight and achieve remission using this approach, which may be easier to adhere to longer term than more intensive total diet replacement and low-carbohydrate strategies. Plant-based diets that advocate for the elimination of animal-based and/or animal-derived foods have increased in popularity. There is evidence from epidemiological studies that people who follow these diets have a lower risk of developing type 2 diabetes, and evidence from trials and systematic reviews of trials that changing to a dietary pattern lower in animal-based and animal-derived foods has benefits on glycaemic control and other markers of cardiovascular disease. While these approaches all provide food or nutrient prescriptions, approaches that incorporate periods of fasting do not provide rules on the types of foods that can or cannot be consumed, but rather provide time windows of when to eat. Evidence suggests that these approaches can be as effective in achieving energy restriction and weight loss as approaches that advocate continuous energy restriction, and there is evidence for benefits on glycaemic control independent of weight loss. Finally, popular dietary strategies that may be useful to use or combine to help prevent postprandial hyperglycaemia include reducing the glycaemic index or glycaemic load of the diet, high-fibre diets, eating foods in a meal in the order vegetables > protein > carbohydrates, preloading or combining acids such as vinegar or lemon juice with meals and engaging in low-intensity aerobic exercise immediately after meals.

The global prevalence of obesity has risen sharply during the past half-century, reaching pandemic proportions and creating a public health crisis. Obesity is a recognized risk factor for the development of diabetes, atherosclerosis, hypertension, hepatic steatosis, and many other cardiometabolic disorders with significant resultant morbidity and mortality. Though treatment of obesity can prevent or slow the progression of the aforementioned illnesses, efforts to help patients achieve reliable and sustainable weight loss have had limited success. Improving nutrition and increasing physical activity results in a host of health benefits; however, the weight loss achieved with lifestyle interventions alone is modest and difficult to sustain. Early attempts at medical and surgical treatment of obesity were plagued with adverse effects and complications. Moreover, these approaches failed to demonstrate long-term health benefits, even when weight loss was achieved. Recently, novel incretin-based therapies targeting glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptors have gained popularity because of their effectiveness in achieving substantial weight loss in patients both with and without diabetes. Following many successful clinical trials, there are now multiple GLP-1 receptor agonists and one dual GLP-1-GIP receptor agonist approved by the Food and Drug Administration for chronic weight management. Advancements in laparoscopic surgical technique and refinements in procedure selection have similarly improved the safety and efficacy of bariatric metabolic surgery for patients with obesity. In this review, we discuss the advantages and disadvantages of contemporary pharmacologic and surgical weight management strategies. We review the data regarding expected weight loss, glycemic control, cardiometabolic benefits, and potential adverse effects of various treatment approaches. As obesity rates continue to rise worldwide, it is imperative that clinicians keep these considerations in mind in order to better care for patients.

Type 2 diabetes mellitus (T2DM) in youth is invading the communities because, if not controlled on time, the long-term complications include cardiovascular diseases, nephropathy, neuropathy, and retinopathy that cause immense mortality and morbidity. Lifestyle changes and antidiabetic drugs are considered the foundation of T2DM therapy. However, these adjustments usually do not effectively produce long-term glycemic regulation, especially in patients with obesity of the third and fourth degrees. Bariatric surgery has also been identified as an efficacious intervention for obesity and obesity-related complications such as T2DM. Roux-en-Y gastric bypass (RYGB) has proven to be one of the most effective procedures in causing considerable weight loss and enhancing glycemic changes. This review provides a comprehensive analysis of RYGB in patients with young-onset T2DM regarding the improvement of glycemic control, weight loss, and diabetes comorbidities. RYGB has been established as a practice in the treatment of T2DM and severe obesity. This narrative review underscores the various effects of RYGB, such as enhanced glycemic control, considerable and long-term weight loss, and reduced cardiovascular disease risks. However, the review also points toward the directions and the adverse effects of RYGB regarding metabolic and skeletal health. There are risks of nutritional deficiencies, increased fracture rates, and even relapse to diabetes, which make patient selection, proper pre and postoperative investigation, and critical monitoring.

Type 2 diabetes mellitus (T2DM) is increasing at an alarming rate, and only 50% of patients with T2DM achieve or maintain adequate glycemic control with pharmacological therapies. Metabolic surgery demonstrated superior efficacy compared to medical therapy but is unfeasible for most patients with T2DM. Duodenal mucosal resurfacing (DMR) by hydrothermal mucosal ablation, recellularization via electroporation therapy (ReCET), and photodynamic therapy are novel endoscopic procedures that use thermal, electrical, and photochemical energy, respectively, to ablate and reset dysfunctional duodenal mucosa. We assessed the data on the effects of these techniques on glycemic control and nonalcoholic fatty liver disease (NAFLD).

We systematically searched independently and in duplicate English and non-English language publications through January 31st, 2024. Outcomes assessed were an improvement in different metabolic health parameters and the safety of duodenal mucosal ablation (DMA) procedures. Outcomes were presented descriptively.

We selected 12 reports reporting results from 3 randomized and 6 uncontrolled trials (seven evaluating DMR, two evaluating ReCET, all with a low risk of bias) for a total of 317 patients enrolled. DMA reduced HbA1c, fasting plasma glucose, and liver fat. When combined with newer antidiabetic drugs, it allowed insulin discontinuation in up to 86% patients. No major safety signal emerged.

All DMA techniques improve glucose homeostasis; DMR and ReCET appear to be safe in patients with T2DM. If confirmed by future randomized trials and by trials with histological endpoints in NAFLD, then DMA appears to be a promising alternative or complement option to medications for T2DM and NAFLD treatment.

Lipodystrophy syndromes are a heterogeneous group of rare, life-limiting diseases characterized by a selective loss of adipose tissue and severe metabolic complications. There is a paucity of information describing the experiences and challenges faced by physicians who have seen and treated patients with lipodystrophy. This study aimed to provide a better understanding of the physician's perspective regarding the patient journey in lipodystrophy, including diagnosis, the burden of disease, and treatment approaches.

Thirty-three physicians from six countries who had seen or treated patients with lipodystrophy were interviewed using a semi-structured questionnaire. Interviews were transcribed, anonymized, and analyzed for themes and trends. Four main themes were developed: (1) the diagnostic journey in lipodystrophy including the disease features or 'triggers' that result in the onward referral of patients to specialist medical centers with experience in managing lipodystrophy; (2) the impact of lipodystrophy on patient quality of life (QoL); (3) the use of standard therapies and leptin replacement therapy (metreleptin) in lipodystrophy, and (4) barriers to metreleptin use.

Participants reported that, due to their rarity and phenotypic heterogeneity, lipodystrophy cases are frequently unrecognized, leading to delays in diagnosis and medical intervention. Early consultation with multidisciplinary specialist medical teams was recommended for suspected lipodystrophy cases. The development and progression of metabolic complications were identified as key triggers for the referral of patients to specialist centers for follow-up care. Participants emphasized the impact of lipodystrophy on patient QoL, including effects on mental health and self-image. Although participants routinely used standard medical therapies to treat specific metabolic complications associated with lipodystrophy, it was acknowledged that metreleptin was typically required in patients with congenital generalized lipodystrophy and in some acquired generalized and partial lipodystrophy cases. A lack of experience among some participants and restrictions to access remained as barriers to metreleptin use.

To our knowledge, this is one of the first studies describing the qualitative experiences of physicians regarding the diagnosis and management of lipodystrophy. Other physician-centered studies may help increase the awareness of lipodystrophy among the wider medical community and support clinical approaches to this rare disease.

Metabolic Dysfunction-Associated Fatty Liver Disease and Diabetes Mellitus are two prevalent metabolic disorders that often coexist and synergistically contribute to the progression of each other. Several pathophysiological pathways are involved in the association, including insulin resistance, inflammation, and lipotoxicity, providing a foundation for understanding the complex interrelationships between these conditions. The presence of MASLD has a significant impact on diabetes risk and the development of microvascular and macrovascular complications, and diabetes significantly contributes to an increased risk of liver fibrosis progression in MASLD and the development of hepatocellular carcinoma. Moreover, both pathologies have a synergistic effect on cardiovascular events and mortality. Therapeutic interventions targeting MASLD and diabetes are discussed, considering lifestyle modifications, pharmacological agents, and emerging treatment modalities. The review also addresses the challenges in managing these comorbidities, such as the need for personalized approaches and the potential impact on cardiovascular health. The insights gleaned from this analysis can inform clinicians, researchers, and policymakers in developing integrated strategies for preventing, diagnosing, and managing these metabolic disorders.

Laparoscopic sleeve gastrectomy combined with fundoplication (LSGFD) can significantly control body weight and achieve effective anti-reflux effects. The aim of this study is to investigate the correlation between the alteration in Ghrelin levels and weight loss following SGFD, and to compare Ghrelin levels, weight loss and metabolic improvements between SG and SGFD, with the objective of contributing to the existing body of knowledge on SGFD technique in the management of patients with obesity and gastroesophageal reflux disease (GERD).

A retrospective analysis was conducted on the clinical data of 115 obese patients who underwent bariatric surgery between March 2023 and June 2023 at the Department of Minimally Invasivew Surgery, Hernia and Abdominal Wall Surgery, People's Hospital of Xinjiang Uygur Autonomous Region. The subjects were divided into two groups based on surgical methods: sleeve gastrectomy group (SG group, 93 cases) and sleeve gastrectomy combined with fundoplication group (SGFD group, 22 cases). Clinical data, such as ghrelin levels before and after the operation, were compared between the two groups, and the correlation between changes in ghrelin levels and weight loss effectiveness after the operation was analyzed.

Three months after the operation, there was no significant difference in body mass, BMI, EWL%, fasting blood glucose, triglyceride, cholesterol, and uric acid levels between the SG and SGFD groups (P > 0.05). However, the SGFD group exhibited a significant decrease in body weight, BMI, and uric acid levels compared to preoperative levels (P < 0.05), while the decrease in ghrelin levels was not statistically significant (P > 0.05). Logistic regression analysis indicated that ghrelin levels three months after the operation were influential in postoperative weight loss.

The reduction of plasma Ghrelin level in patients after SGFD is not as obvious as that in patients after SG, but it can make obese patients get the same good weight loss and metabolic improvement as patients after SG. Ghrelin level at the third month after operation is the influencing factor of postoperative weight loss.

Evidence regarding the relative effectiveness of bariatric metabolic surgery (BMS) and glucagon-like peptide-1 receptor agonists (GLP-1RAs) in reducing mortality and major adverse cardiovascular events (MACEs) is limited.

To compare all-cause mortality and nonfatal MACEs associated with BMS vs GLP-1RAs for adults with obesity and diabetes and without known cardiovascular disease.

This observational, retrospective cohort study was based on data obtained from the electronic medical records of Clalit Health Services (Clalit), the largest health care organization in Israel. The study included 6070 members aged 24 years or older, who had diabetes and obesity and no prior history of ischemic heart disease, ischemic stroke, or congestive heart failure. Patients who underwent BMS and patients who received GLP-1RAs from January 1, 2008, through December 31, 2021, were matched 1:1 by age, sex, and clinical characteristics. Follow-up ended December 31, 2022.

Initiation of BMS or GLP-1RAs.

The primary outcome was all-cause mortality, assessed by multivariate Cox proportional hazards regression models. The secondary outcome was nonfatal MACEs, assessed by multivariate competing risk models.

The study included 3035 matched pairs of patients (total, 6070; mean [SD] age, 51.0 [9.5] years; 3938 women [64.9%]), who were followed up for a median of 6.8 years (IQR, 4.1-9.4 years). Among those with a diabetes duration of 10 years or less (2371 pairs), mortality was lower for those who underwent BMS than for those treated with GLP-1RAs (hazard ratio [HR], 0.38; 95% CI, 0.25-0.58). This association became nonsignificant when weight loss during the follow-up period was also included in the model (HR, 0.79; 95% CI, 0.43-1.48). Among patients with a duration of diabetes longer than 10 years (664 pairs), no survival advantage was demonstrated for BMS over GLP-1RA (HR, 0.65; 95% CI, 0.39-1.08). The risk for nonfatal MACEs did not differ between the treatment groups (HR, 0.74; 95% CI, 0.49-1.10 among patients with a diabetes duration of ≤10 years; HR, 1.21; 95% CI, 0.80-1.85 among patients with a diabetes duration of >10 years).

In this cohort study, BMS was associated with greater reduced mortality compared with first-generation GLP-1RAs among individuals with a diabetes duration of 10 years or less, mediated via greater weight loss. No differences in the risk for mortality were observed between the treatment modalities among individuals with a longer duration of diabetes, nor in the occurrence of nonfatal MACEs among all patients.

Bariatric metabolic surgery's global research interest is growing, particularly in Asia due to its high obesity rates. This study focuses on Asia, especially China, analyzing 3904 publications (1221 from China) from 1980 to 2022. Research output accelerated until the COVID-19 pandemic, driven by economic growth and rising obesity rates. China led contributions from 2010, but Western Asia led when adjusted for population. An intra-regional research collaboration network emerged, driven by geographic proximity and similar economic environments. Keyword analysis highlighted emerging topics like "laparoscopic sleeve gastrectomy" and "non-alcoholic fatty liver disease," indicating a shift in focus. The study recommends disseminating research in top-tier journals to enhance visibility and impact.

Post-bariatric hypoglycaemia (PBH) is a rare yet disabling clinical condition, mostly reported after Roux-en-Y gastric bypass (RYGB) surgery. RYGB is one of the most widely used and effective bariatric procedures. The pathophysiology of PBH remains unclear, and treatment options are limited in effectiveness and/or carry significant side effects. Acarbose slows carbohydrates digestion and absorption and is generally considered first-line pharmacological treatment for PBH but its gastrointestinal side effects limit patient compliance. Canagliflozin inhibits intestinal and renal sodium-dependent glucose absorption and reduces postprandial excursions of glucose, insulin and incretins after RYGB - effects that could be beneficial in ameliorating PBH.

The trial aims to investigate how blood glucose levels are affected during daily living in subjects with PBH during treatment with canagliflozin or acarbose compared with placebo, and to study the meal-induced entero-endocrine mechanisms implied in the treatment responses.

In a double-blinded, randomized, crossover clinical trial, HypoBar I will investigate the effectiveness in reducing the risk of PBH, safety, ambulatory glucose profile and entero-endocrine responses when PBH is treated with canagliflozin 300 mg twice daily during a 4-week intervention period, compared with acarbose 50 mg thrice daily or placebo.

HypoBar I is approved by the Local regulatory entities. Results will be published in peer-reviewed journals.

If effective, well-tolerated and safe, canagliflozin could be a novel treatment for people with PBH. HypoBar I might also unravel new mechanisms underlying PBH, potentially identifying new treatment targets.

Knowing how metabolic and bariatric surgery (MBS) is indicated in different countries is essential information for the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO).

To analyze the indications for MBS recommended by each of the national societies that comprise the IFSO and how MBS is financed in their countries.

All IFSO societies were asked to fill out a survey asking whether they have, and which are their national guidelines, and if MBS is covered by their public health service.

Sixty-three out of the 72 IFSO national societies answered the form (87.5%). Among them, 74.6% have some kind of guidelines regarding indications for MBS. Twenty-two percent are still based on the US National Institute of Health (NIH) 1991 recommendations, 43.5% possess guidelines midway the 1991s and ASMBS/IFSO 2022 ones, and 34% have already adopted the latest ASMBS/IFSO 2022 guidelines. MBS was financially covered in 65% of the countries.

Most of the IFSO member societies have MBS guidelines. While more than a third of them have already shifted to the most updated ASMBS/IFSO 2022 ones, another significant number of countries are still following the NIH 1991 guidelines or even do not have any at all. Besides, there is a significant number of countries in which surgical treatment is not yet financially covered. More effort is needed to standardize indications worldwide and to influence insurers and health policymakers to increase the coverage of MBS.

Chronic weight management and treatments for type 2 diabetes (T2D) involve a combination of lifestyle-based (diet, exercise) and pharmaceutical interventions. In people with obesity or T2D, understanding the impact of drivers/triggers on appetite and eating behaviors can be crucial to successful medical management. This study aimed to characterize perceptions and experiences regarding appetite and eating behaviors among people with obesity or T2D and identify drivers/triggers of food choices.

This non-interventional, cross-sectional, qualitative study utilized semi-structured concept elicitation interviews to explore the perceptions of people with obesity and/or T2D around appetite, eating behaviors and drivers/triggers of food choices. Adult US residents (≥ 18 years) with stable body weight (± 5 kg) in the 3 months preceding participation were included in the study.

Forty-five participants (obesity: n = 15; overweight: n = 10; T2D: n = 20) were interviewed. Interviews were audio-recorded and transcribed verbatim for analysis. A subset of participants described eating behaviors on smartphone-based app tasks over 5 days. Most (> 96%) discussed the influence of hunger, cravings and satiety on food choices. Participants identified 22 drivers/triggers (including health, 95.6%; culture/heritage, 93.3%; location, 91.1%; stress, 88.8%). Participants also discussed associations between drivers/triggers and eating behavior concepts (appetite, hunger, cravings, satiety, motivation/determination). A conceptual model illustrating eating behavior concepts and related drivers/triggers was developed. The concept elicitation interviews identified a multitude of drivers and triggers and characterized the association of such drivers/triggers with seven core patient-reported concepts encompassing eating behaviors.

The findings build upon existing models of factors influencing food choices. Findings confirm prior research regarding impact of drivers/triggers on food choice in people with obesity and T2D and indicate underlying disease state does not appear to influence eating behaviors in people with stable body weight.

Although bariatric surgery is an effective treatment for type 2 diabetes by inducing weight loss and augmenting gut hormone secretion, the immediate effect on beta-cell function itself remains to be elucidated in type 2 diabetes. Therefore, a prospective, randomized trial was performed in 30 patients with insulin-treated type 2 diabetes and a body mass index ≥ 35 kg/m2. Patients were randomly assigned (1:1:1) to Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) in combination with protein-sparing modified fast (PSMF), or to PSMF alone. Eu- and hyperglycemic clamps were performed before and 3 weeks after surgery and/or PSMF initiation. The primary outcome was the evolution of insulin sensitivity and beta-cell function after surgery, calculated using the composite measures of glucose disposal rate, insulin secretion rate, and disposition index (DI). Results revealed that markers of insulin sensitivity increased similarly in all arms (p = 0.43). A higher marker for maximal beta-cell function was observed when comparing SG to PSMF (p = 0.007). The DI showed a clear positive evolution after RYGB and SG, but not after PSMF alone. Altogether, these findings indicate that bariatric surgery results in an immediate beta-cell function recovery in insulin-treated type 2 diabetes.

An elevated triglyceride-glucose (TyG) level is associated with increased risk of mortality in patients with CAD. Trimethylamine N-oxide (TMAO) has mechanistic links to atherosclerotic coronary artery disease (CAD) pathogenesis and is correlated with adverse outcomes. However, the incremental prognostic value of TMAO and TyG in the cohort of optical coherence tomography (OCT)-defined high-risk ST-segment elevation myocardial infarction (STEMI) patients is unknown.

We studied 274 consecutive aged ≥18 years patients with evidence of STEMI and detected on pre-intervention OCT imaging of culprit lesions between March 2017 and March 2019.

There were 22 (22.68%), 27 (27.84%), 26 (26.80%), and 22 (22.68%) patients in groups A-D, respectively. The baseline characteristics according to the level of TMAO and TyG showed that patients with higher level in both indicators were more likely to have higher triglycerides (p < 0.001), fasting glucose (p < 0.001) and higher incidence of diabetes (p = 0.008). The group with TMAO > median and TyG ≤ median was associated with higher rates of MACEs significantly (p = 0.009) in fully adjusted analyses. During a median follow-up of 2.027 years, 20 (20.6%) patients experienced MACEs. To evaluate the diagnostic value of the TyG index combined with TMAO, the area under the receiver operating characteristic curve for predicting MACEs after full adjustment was 0.815 (95% confidence interval, 0.723-0.887; sensitivity, 85.00%; specificity, 72.73%; cut-off level, 0.577). Among the group of patients with TMAO > median and TyG ≤ median, there was a significantly higher incidence of MACEs (p=0.033). A similar tendency was found in the cohort with hyperlipidemia (p=0.016) and diabetes mellitus (p=0.036).

This study demonstrated the usefulness of combined measures of the TyG index and TMAO in enhancing risk stratification in STEMI patients with OCT-defined high-risk plaque characteristics.

This study was registered at ClinicalTrials.gov as NCT03593928.

Changes in healthcare utilisation and expenditures after bariatric-metabolic surgery (BMS) for people with type 2 diabetes mellitus (T2DM) are unclear. We used the Dutch national all-payer claims database (APCD) to evaluate utilisation and expenditures in people with T2DM who underwent BMS.

In this cohort study, patients with T2DM who had BMS in 2016 were identified in the APCD. This group was matched 1:2 to a control group with T2DM who did not undergo BMS based on age, gender and healthcare expenditures. Data on healthcare expenditures and utilisation were collected for 2013-2019.

In total, 1751 patients were included in the surgery group and 3502 in the control group. After BMS, total median expenditures in the surgery group stabilised (€ 3156 to € 3120) and increased in the control group (€ 3174 to € 3434). Total pharmaceutical expenditures decreased 28% in the surgery group (€957 to €494) and increased 55% in the control group (€605 to €936). In the surgery group, 67.1% did not use medication for T2DM in 2019 compared to 13.3% in the control group. Healthcare use for microvascular complications increased in the control group, but not in the surgery group.

BMS in people with T2DM stabilises healthcare expenditures and decreases medication use and care use for microvascular complications. In contrast, healthcare use and expenditures in T2DM patients who do not undergo surgery gradually increase over time. Due to the progressive nature of T2DM, it is expected that these differences will become larger in the long-term.

Randomized clinical trials of bariatric surgery have been limited in size, type of surgical procedure, and follow-up duration.

To determine long-term glycemic control and safety of bariatric surgery compared with medical/lifestyle management of type 2 diabetes.

ARMMS-T2D (Alliance of Randomized Trials of Medicine vs Metabolic Surgery in Type 2 Diabetes) is a pooled analysis from 4 US single-center randomized trials conducted between May 2007 and August 2013, with observational follow-up through July 2022.
