[PMID: 38911638 PMCID: PMC11192007 DOI: 10.1097/as9.0000000000000414] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2024] [Accepted: 03/11/2024] [Indexed: 06/25/2024] Open
Abstract
Objective To assess the external validity of randomized controlled trials (RCTs) of bariatric surgical treatment on diabetes control. Background Multisite RCTs provide the strongest evidence supporting clinical treatments and have the greatest internal validity. However, characteristics of trial participants may not be representative of patients receiving treatment in the real world. There is a need to assess how the results of RCTs generalize to all contemporary patient populations undergoing treatments. Methods All patients undergoing sleeve gastrectomy at University of California Los Angeles (UCLA) between January 8, 2018 and May 19, 2023 had their baseline characteristics, weight change, and diabetes control compared with those enrolled in the surgical treatment and medications potentially eradicate diabetes efficiently (STAMPEDE) and diabetes surgery study (DSS) RCTs of bariatric surgery's effect on diabetes control. Weight loss and diabetes control were compared between UCLA patients who did and did not fit the entry criteria for these RCTs. Results Only 65 (17%) of 387 patients with diabetes fulfilled the eligibility criteria for STAMPEDE, and 29 (7.5%) fulfilled the criteria for DSS due to being older, having higher body mass index, and lower HbA1c. UCLA patients experienced slightly less weight loss than patients in the RCTs but had similar diabetes control. The 313 (81%) patients not eligible for study entry into either RCT had similar long-term diabetes control as those who were eligible for the RCTs. Conclusions Even though only a very small proportion of patients undergoing bariatric surgery met the eligibility criteria for the 2 major RCTs, most patients in this contemporary cohort had similar outcomes. Diabetes outcomes from STAMPEDE and DSS generalize to most patients undergoing bariatric surgery for diabetes control.

Surgery 2024:S0039-6060(24)00181-8. [PMID: 38769035 DOI: 10.1016/j.surg.2024.02.035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Revised: 01/23/2024] [Accepted: 02/25/2024] [Indexed: 05/22/2024]
Abstract
BACKGROUND Laparoscopic Roux-en-Y gastric bypass has a well-established safety and efficacy profile in the short and mid-term. Long-term outcomes remain limited in the literature, especially for follow-up periods of >10 years. The purpose of the study is to evaluate the long-term durability and safety of laparoscopic Roux-en-Y gastric bypass over a near-complete 15-year follow-up. METHODS This is a single-center retrospective cohort study of patients who underwent primary laparoscopic Roux-en-Y gastric bypass between 2008 and 2009 with ≥14-year follow-up. Data collected and analyzed were weight loss, obesity-related medical condition resolution and recurrence, weight recurrence, complication rate, and mortality rate. RESULTS A total of 264 patients were included. Patients were predominantly female (81.8%), and the mean age and preoperative body mass index were 48.5 ± 12.2 years and 44.9 ± 7.3 kg/m2, respectively. The maximum mean percentage total weight loss achieved at 1 year was 31.5% ± 5.7% and was consistently >20% throughout follow-up. Sustained resolution of obesity-related medical conditions was achieved with a remission rate of 60.8% for type 2 diabetes mellitus, 46.7% for denoted dyslipidemia, and 40% for hypertension. Obesity-related medical condition recurrence was observed with a recurrence rate of 24.1% for type 2 diabetes mellitus, 17.9% for hypertension, and 14.8% for denoted dyslipidemia. Significant factors associated with weight loss were maximum percentage total weight loss and preoperative type 2 diabetes mellitus. Over 15 years, the weight recurrence rate was 51.1%, with predictors of higher preoperative body mass index and preoperative type 2 diabetes mellitus. CONCLUSION Laparoscopic Roux-en-Y gastric bypass provides sustainable weight loss over a 15-year period, with consistent long-term weight-loss outcomes and resolution of obesity-related medical conditions sustained for ≥10 years after surgery.

Insurance payor status and risk of major adverse cardiovascular and cerebrovascular events after metabolic and bariatric surgery. Surg Obes Relat Dis 2024:S1550-7289(24)00174-6. [PMID: 38849260 DOI: 10.1016/j.soard.2024.04.017] [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: 01/05/2024] [Revised: 03/13/2024] [Accepted: 04/26/2024] [Indexed: 06/09/2024]
Abstract
BACKGROUND Patients with Medicare/Medicaid insurance receive metabolic and bariatric surgery (MBS) at lower rates than privately insured (PI) patients. Although studies on some surgical procedures report that Medicare/Medicaid insurance confers increased postoperative complication rates and a longer length of stay, less is known about these outcomes after MBS. Among often-feared postoperative complications are major adverse cardiovascular and cerebrovascular events (MACEs). Although these events are rare after MBS, they have a significant impact on morbidity and mortality. OBJECTIVES This study aimed to examine the effect of insurance payor status on MACEs after MBS. SETTING The Healthcare Cost and Utilization Project National Inpatient Sample (HCUP-NIS). METHODS HCUP-NIS was queried for cases including sleeve gastrectomy or Roux-en-Y gastric bypass between 2012 and 2019. Bivariate associations between patient-level factors and MACEs were assessed via Rao-Scott χ2 tests. Adjusted and unadjusted risks of insurance payor status for MACEs were evaluated using logistic regression. RESULTS Incidence of MACEs was higher in both Medicare (.75% versus .11%; P < .001) and Medicaid (.15% versus .11%; P < .001) groups than in the PI group. After adjustment for high-risk demographics, high-risk co-morbidities, socioeconomic variables, and hospital factors, insurance status of Medicare (odds ratio [OR]: 1.60, 95% confidence interval [CI]: 1.23, 2.07; P = .0026) or Medicaid (OR: 1.55, 95% CI: 1.12, 2.16; P = .0026) remained an independent risk factor for MACEs. CONCLUSIONS Our findings underscore the significance of Medicaid/Medicare payor status as an independent predictor of postoperative MACEs in MBS. The results of this study can have a significant impact on deepening our understanding of socioeconomic and health system-related issues that can be targeted to improve outcomes in both MBS and other surgical specialties.

Abstract
BACKGROUND Roux-en-Y gastric bypass (RYGB) demonstrates high rates of type 2 diabetes mellitus (T2DM) remission, a phenomenon hypothesized to be mediated mainly by weight loss. Compared with procedures that do not bypass the proximal small intestines, such as sleeve gastrectomy (SG), RYGB exhibits weight loss-independent intestinal mechanisms conducive to T2DM remission. We investigated continued diabetes remission (CDR) rates despite weight recurrence (WR) after RYGB compared with an SG cohort. STUDY DESIGN A retrospective review of patients who underwent successful primary RYGB or SG with a BMI value of 35 kg/m 2 or more and a preoperative diagnosis of T2DM was performed. Patients with less than 5 years of follow-up, absence of WR, or lack of T2DM remission at nadir weight were excluded. After selecting the optimal procedure for glycemic control, rates of CDR were then stratified into WR quartiles and compared. RESULTS A total of 224 RYGB and 46 SG patients were analyzed. The overall rate of CDR was significantly higher in the RYGB group (75%) compared with the SG group (34.8%; p < 0.001). The odds of T2DM recurrence were 5.5 times higher after SG compared with RYGB. Rates of CDR were stratified into WR quartiles (85.5%, <25%; 81.7%, 25% to 44.9%; 63.2%, 45% to 74.9%; and 60%, >75%). Baseline insulin use, higher preoperative glycosylated hemoglobin, and longer preoperative duration of T2DM were associated with T2DM recurrence, whereas WR was not. CONCLUSIONS T2DM remission rates after RYGB are maintained despite WR, arguing for a concurrent weight loss-independent metabolic benefit likely facilitated by bypassing the proximal small intestine.

Abstract
Obesity and type 2 diabetes (T2D) are growing global health concerns. Evidence suggests that Indigenous peoples are at higher lifetime risk of obesity and its associated conditions. Obesity increases the risk of T2D, cardiovascular disease, and all-cause mortality. Bariatric surgery is the most sustained and effective intervention for treating obesity-associated medical problems. This review aims to explore the experiences and outcomes of Indigenous peoples undergoing bariatric surgery in Canada, the USA, Australia, and New Zealand (CANZUS). Analysis of quantitative data revealed that Indigenous patients had fewer bariatric procedures, poorer clinic attendance, similar weight loss outcomes and slightly higher post-operative complication rates. Qualitative data analysis revealed that Indigenous patients living with obesity have a desire to improve their health and quality of life.

Abstract
The preservation of pancreatic islet β-cells is crucial in diabetes mellitus, encompassing both type 1 and type 2 diabetes. β-cell dysfunction, reduced mass, and apoptosis are central to insufficient insulin secretion in both types. Research is focused on understanding β-cell characteristics and the factors regulating their function to develop novel therapeutic approaches. In type 1 diabetes (T1D), β-cell destruction by the immune system calls for exploring immunosuppressive therapies, non-steroidal anti-inflammatory drugs, and leukotriene antagonists. Islet transplantation, stem cell therapy, and xenogeneic transplantation offer promising strategies for type 1 diabetes treatment. For type 2 diabetes (T2D), lifestyle changes like weight loss and exercise enhance insulin sensitivity and maintain β-cell function. Additionally, various pharmacological approaches, such as cytokine inhibitors and protein kinase inhibitors, are being investigated to protect β-cells from inflammation and glucotoxicity. Bariatric surgery emerges as an effective treatment for obesity and T2D by promoting β-cell survival and function. It improves insulin sensitivity, modulates gut hormones, and expands β-cell mass, leading to diabetes remission and better glycemic control. In conclusion, preserving β-cells offers a promising approach to managing both types of diabetes. By combining lifestyle modifications, targeted pharmacological interventions, and advanced therapies like stem cell transplantation and bariatric surgery, we have a significant chance to preserve β-cell function and enhance glucose regulation in diabetic patients.

Abstract
INTRODUCTION 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. PATIENTS AND METHODS 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 1st-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 5th year. RESULTS In the 1st 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. CONCLUSIONS 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.

Abstract
BACKGROUND AND GOAL The pandemic of the twenty-first century is diabetes. Both type 2 diabetes mellitus and obesity pose severe problems for public health. Despite significant improvements in diagnosing and managing both conditions, diabetes mellitus remains poorly controlled, and diabetic complications are more common than ever. Internists have discovered over the past 20 years that obese people with type 2 diabetes who have gastric bypass surgery to shed weight have improved glycemic control. Thus, interventional diabetology has a growing significance in patients' ability to reverse type 2 diabetes mellitus. We want to evaluate the impact of gastric bypass on blood sugar regulation and look for potential causes. PATIENTS AND METHODS Between 2018 and 2020, a prospective interventional study was carried out. Ninety patients in total were enrolled in the trial. The two patient groups (A and B) contained 45 obese T2DM patients with a body mass index (BMI) of over 35 kg/m2. Group B received its antidiabetic medications, either oral hypoglycemic or insulin, while Group A underwent gastric bypass surgery. Each patient underwent a comprehensive history review and clinical assessment. Both groups had their HA1c and blood sugar levels measured; group A had their insulin, GLP-1, and HOMA-IR (Homeostasis Model Assessment for Insulin Resistance) levels calculated at time O and one year later. RESULTS The demographic differences between the two study groups were negligible. After a one-year follow-up, group A had significantly lower anthropometric measurement data for BMI and waist circumference (cm), lipid profile data for triglycerides, total cholesterol, and LDL levels, and systolic and diastolic blood pressure. Fasting plasma glucose and HbA1c, two metrics of glucose metabolism, significantly decreased in group A. Regarding indicators of glucose metabolism, there was a drop in fasting insulin level and HOMA-IR and an increase in GLP1 level in the gastric bypass group. CONCLUSION As a result of improving all indicators, gastric bypass is an effective treatment for patients with uncontrolled T2DM. Future research that is confirmed is needed.

Abstract
Objective Bariatric procedures have become safer in recent years, warranting new data on long-term costs. This study examined the impact of bariatric procedures on a person's long-term healthcare costs up to 10 years and if it differed by socio-economic status (SES). Methods This retrospective observational study compared the downstream health care cost of patients with obesity who had undergone bariatric surgery (BS) between 2009 and 2018 to a 1:1 matched group of members with obesity but no surgery. Results 167,764 individuals from administrative claims data with an obesity diagnosis were included; 83,882 in the BS group and 83,882 in the non-surgical group. In follow-up years 2-10, the BS group was associated with lower total medical healthcare cost compared to the non-surgical group (cost ratios ranged 0.85-0.93, p values < 0.05). When stratifying the BS group by SES quartiles, there were no significant cost differences by SES (cost ratios ranged from 0.96 to 1.05, most p values > 0.05). Conclusions BS was associated with lower long-term follow-up medical cost and cost savings appeared similar among the SES quartiles in the BS group. The study results may help policy makers and employers in designing benefits and extending coverage for bariatric surgical procedures.

Abstract
INTRODUCTION We still lack studies providing analysis of changes in glucose and lipid metabolism after laparoscopic sleeve gastrectomy (LSG) in patients with type 2 diabetes mellitus (DM2). We aimed to investigate postoperative changes in glucose and lipid metabolism after LSG in patients with DM2. MATERIAL AND METHODS Prospective, observational study included patients with BMI ≥ 35 kg/m2 and ≤ 50 kg/m2, DM2 < 10 years of duration, who were qualified for LSG. Perioperative 14-day continuous glucose monitoring (CGM) began after preoperative clinical assessment and OGTT, then reassessment 1 and 12 months after LSG. Thirty-three patients in mean age of 45 ± 10 years were included in study (23 females). RESULTS EBMIL before LSG was 17 ± 11.7%, after 1 month-36.3 ± 12.8%, while after 12 months-66.1 ± 21.7%. Fifty-two percent of the patients had DM2 remission after 12 months. None required then insulin therapy. 16/33 patients initially on oral antidiabetics still required them after 12 months. Significant decrease in HbA1C was observed: 5.96 ± 0.73%; 5.71 ± 0.80; 5.54 ± 0.52%. Same with HOMA-IR: 5.34 ± 2.84; 4.62 ± 3.78; 3.20 ± 1.99. In OGTT, lower increase in blood glucose with lesser insulin concentrations needed to recover glucose homeostasis was observed during follow-ups. Overtime perioperative average glucose concentration in CGM of 5.03 ± 1.09 mmol/L significantly differed after 12 months, 4.60 ± 0.53 (p = 0.042). Significantly higher percentage of glucose concentrations above targeted compartment (3.9-6.7 mmol/L) was observed in perioperative period (7% ± 4%), than in follow-up (4 ± 6% and 2 ± 1%). HDL significantly rose, while triglyceride levels significantly decreased. CONCLUSIONS Significant improvement in glucose and lipid metabolism was observed 12 months after LSG and changes began 1 month after procedure.

Cao Y, Luo P, Tang H, Li P, Wang G, Li W, Song Z, Su Z, Sun X, Yi X, Fu Z, Cui B, Zhu S, Zhu L. Insulin resistance levels predicted metabolic improvement and weight loss after metabolic surgery in Chinese patients with type 2 diabetes. Surg Obes Relat Dis 2024; 20:80-90. [PMID: 37739868 DOI: 10.1016/j.soard.2023.08.004] [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: 06/04/2023] [Revised: 07/12/2023] [Accepted: 08/05/2023] [Indexed: 09/24/2023]
Abstract
BACKGROUND The causes for failure of metabolic improvement and inadequate weight loss after metabolic surgery (MS) in Chinese patients with type 2 diabetes (T2D) have not been fully elucidated. The effect of insulin resistance (IR) on the outcome of T2D, hypertension, hyperlipidemia, and obesity after MS in Chinese patients with T2D and a body mass index (BMI) of 25-32.5 kg/m2 warrants further study. OBJECTIVES Patients with T2D and a BMI of 25-32.5 kg/m2 who underwent MS between July 2019 and June 2021 were included. SETTING University hospital, China. METHODS IR levels were evaluated with the glucose disposal rate (GDR). Improvement of T2D, hypertension, and hyperlipidemia was assessed with the composite triple endpoint (CTEP), and weight loss was assessed with the percent of total weight loss (%TWL). Partial correlation analysis, binary logistic regression analysis, multiple linear regression analysis, receiver operating characteristic curve (ROC) analysis, and subgroup analysis were used to analyze the relationship between the CTEP, %TWL at 1 year postoperative, and GDR preoperative. RESULTS This study analyzed the data of 51 patients with T2D and a BMI of 25-32.5 kg/m2 (30 men and 21 women) with a mean preoperative GDR of 3.72 ± 1.48 mg/kg/min. Partial correlation coefficients between CTEP, %TWL, and GDR were .303 (P = .041) and .449 (P = .001), respectively. The preoperative GDR was significantly positively correlated with CTEP (OR = 1.610, P = .024) and %TWL (β = 1.38, P = .003). The preoperative GDR predicted cutoff values of 4.36 and 5.35 mg/kg/min for CTEP attainment and %TWL ≥ 20%, respectively. CONCLUSION IR levels predicted metabolic improvement and weight loss 1 year after MS in Chinese patients with T2D and a BMI of 25-32.5 kg/m2.

Abstract
BACKGROUND Obesity is related to cardiovascular risk factors (CVRF) such as dyslipidemia, diabetes, and hypertension, which increase mortality. Basic lipid determinations could underestimate the true atherogenic risk of patients and the impact of bariatric surgery. The objective of the study is to demonstrate the change in the advanced molecular profile of lipoproteins determined by nuclear magnetic resonance spectroscopy in plasma after bariatric surgery, thus reducing the risk of cardiovascular disease. MATERIAL AND METHODS Descriptive, observational, and prospective study in obese patients undergoing bariatric surgery. Advanced lipid profile was analyzed in plasma from the immediate preoperative period and at the 18th postoperative month by sending samples and performing plasma magnetic resonance spectroscopy in the BiosferTreslab® laboratory. RESULTS Fifty-two patients were included. Average age of 46.3 years; 63.46% were women, 36.54% men. The average BMI was 43.57; the abdominal perimeter 133.50 cm; 32.6% were diabetics under medical treatment, 44.23% hypertensive, and 19.23% smokers; 86.53% of the patients presented alterations in at least one of the analytical parameters in the lipid study. Twenty-nine (55.7%) underwent banded gastric bypass (PGB), 19.23% underwent GBP, and 17.31% vertical gastrectomy. The rest were revision surgeries, two BPG-A and two biliopancreatic diversions after GV. All patients presented some improvement in advanced molecular profile of lipoproteins. Twenty percent of the patients normalized all the parameters. CONCLUSIONS Bariatric surgery improves advanced molecular profile of lipoproteins, decreasing CVRF. Analysis of the characteristics of lipoprotein particles by NMR spectrometry is optimal for studying lipoprotein metabolism in patients undergoing bariatric surgery.

Abstract
Metabolic surgery (MS) is a surgery that focuses on improving obesity-related comorbidities. It is often referred to as "diabetic surgery" because of its focus on treating type 2 diabetes. MS is distinguished from bariatric surgery (BS), in which weight loss is the primary goal. However, from a broader perspective, all surgeries for obese patients with diabetes can be considered MS. In Korea, metabolic and bariatric surgery (MBS) has been covered by the national health insurance since 2019. Patients with a body mass index (BMI) ≥35 or those with a BMI ≥30 and obesity-related comorbidities were eligible for MBS. Simultaneously, MS for patients with BMI values between 27.5 and 30 was partly reimbursed. The two major metabolic surgeries are Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). According to the registry of the Korean Society of Metabolic and Bariatric Surgery, 1,560 metabolic surgeries for obese patients with diabetes were performed between 2019 and 2021 in Korea, which was approximately 35.6% of all bariatric surgeries. SG was the most common, followed by RYGB and duodenal switch surgery. When dividing the patients with diabetes who underwent MBS into two groups, specifically those with BMI <35 and ≥35, we found that SG was performed most common procedure in both groups. However, there was a higher proportion of RYGB and duodenal switch operation in the former, indicating a difference in surgical methods between the two groups. MS is a promising tool for the management of poorly controlled diabetes. More data are needed to establish proper patient selection and choice of surgical type.

Abstract
Inputs and Outputs The Strike-a-Match Function, written in JavaScript version ES6+, accepts the input of two datasets (one dataset defining eligibility criteria for research studies or clinical decision support, and one dataset defining characteristics for an individual patient). It returns an output signaling whether the patient characteristics are a match for the eligibility criteria. Purpose Ultimately, such a system will play a "matchmaker" role in facilitating point-of-care recognition of patient-specific clinical decision support. Specifications The eligibility criteria are defined in HL7 FHIR (version R5) EvidenceVariable Resource JSON structure. The patient characteristics are provided in an FHIR Bundle Resource JSON including one Patient Resource and one or more Observation and Condition Resources which could be obtained from the patient's electronic health record. Application The Strike-a-Match Function determines whether or not the patient is a match to the eligibility criteria and an Eligibility Criteria Matching Software Demonstration interface provides a human-readable display of matching results by criteria for the clinician or patient to consider. This is the first software application, serving as proof of principle, that compares patient characteristics and eligibility criteria with all data exchanged using HL7 FHIR JSON. An Eligibility Criteria Matching Software Library at https://fevir.net/110192 provides a method for sharing functions using the same information model.

Abstract
Obesity has emerged as a critical and urgent health burden during the current global pandemic. Among multiple genetic causes, melanocortin receptor-4 (MC4R), involved in food intake and energy metabolism regulation through various signaling pathways, has been reported to be the lead genetic factor in severe and early onset obesity and hyperphagia disorders. Most previous studies have illustrated the roles of MC4R signaling in energy intake versus expenditure in the central system, while some evidence indicates that MC4R is also expressed in peripheral systems, such as the gut and endocrine organs. However, its physiopathological function remains poorly defined. This review aims to depict the central and peripheral roles of MC4R in energy metabolism and endocrine hormone homeostasis, the diversity of phenotypes, biased downstream signaling caused by distinct MC4R mutations, and current drug development targeting the receptor.

Obes Surg 2023; 33:2269-2275.

Abstract
INTRODUCTION The type 2 diabetes (T2D) improvement rate in the elderly is high after bariatric and metabolic surgery, but not all patients achieve complete remission of disease. There are some predictors for T2D remission after bariatric surgery in patients of different ages, but there are few studies describing these factors in elderly patients. The study aimed to determine predictors for diabetes remission after bariatric surgery among patients over 65 years of age. MATERIAL AND METHODS A retrospective study analyzed patients over 65 years with T2D who underwent laparoscopic bariatric procedures in European country from 2008 to 2022. Multivariate logistic regression analysis was performed to obtain significant, independent risk factors. RESULTS The group consisted of 146 patients divided into two groups: responders (R) and nonresponders (NR). The complete remission of T2D was achieved in 51 (34.9%) patients. There were 95 (65.1%) patients in the NR group with partial remission, improvement, or no changes in T2D. The mean follow-up was 50.0 months. In a multivariate logistic regression analysis, a T2D duration of less than 5 years was found to be a predictor to T2D remission (OR = 5.5, p = 0.002), %EWL significantly corresponded to T2D remission (OR = 1.090, p = 0009). CONCLUSION Bariatric and metabolic surgery appears to be a good option for T2D treatment in elderly patients. A shorter duration of T2D before surgery and higher %EWL after surgery were independent predictors of T2D remission in patients over 65 years of age.

Abstract
Obesity is a growing public health epidemic worldwide and is implicated in slowing improved life expectancy and increasing cardiovascular (CV) risk; indeed, several obesity-related mechanisms drive structural, functional, humoral, and hemodynamic heart alterations. On the other hand, obesity may indirectly cause CV disease, mediated through different obesity-associated comorbidities. Diet and physical activity are key points in preventing CV disease and reducing CV risk; however, these strategies alone are not always sufficient, so other approaches, such as pharmacological treatments and bariatric surgery, must support them. Moreover, these strategies are associated with improved CV risk factors and effectively reduce the incidence of death and CV events such as myocardial infarction and stroke; consequently, an individualized care plan with a multidisciplinary approach is recommended. More precisely, this review explores several interventions (diet, physical activity, pharmacological and surgical treatments) to address CV risk in obese patients and emphasizes the importance of adherence to treatments.

Abstract
INTRODUCTION Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) are common bariatric procedures that are effective in treating type 2 diabetes (T2D) in patients with obesity. Limited data from randomized trials are available comparing longevity of diabetes remission directly between the two procedures beyond 5 years. METHODS A prospective, randomized, parallel, two-arm, clinical trial comparing the outcomes of silastic ring (SR)-LRYGB versus LSG was conducted at a single (Auckland, New Zealand) center. Patients and researchers were blinded until the 5-year mark and follow-up after this was unblinded. Eligible patients had T2D of > 6 months duration with a BMI 35--65 kg/m2 and were aged 20-55 years. Randomization was 1:1 to SR-LRYGB and LSG following induction of anesthesia and was stratified by age group, BMI group, ethnicity, diabetes duration, and insulin therapy. The primary outcome was T2D remission, defined as HbA1c < 6% (42 mmol/mol), without the use of glucose-lowering medications. RESULTS A total of 114 patients were randomized of whom 6 died before the 7-year follow-up (2 SR-LRYGB, 4 LSG). Diabetes remission, assessed in 89 (82.4%) of the remaining patients, was seen in 23/50 (46.0%) after SR-LRYGB and 12/39 (30.8%) after LSG (adjusted OR 4.64, 95% CI 1.39, 15.52, p = 0.013). Percentage total body weight loss was greater after SR-LRYGB than LSG (26.2% vs 13.4%; absolute difference 12.8%; 95% CI 7.2%, 18.2%; p < 0.001). Complication rates were similar between groups. CONCLUSION SR-LRYGB was superior to LSG for diabetes remission and weight loss at 7 years following surgery, with acceptable complication rates.

Abstract
Objective Metabolic and morphological adaptations of the intestine have been suggested to play a role in the various therapeutic benefits of Roux-en-Y Gastric Bypass (RYGB) surgery. However, the precise underlying mechanisms remain unclear. In this study, the effects of physical properties of ingested food and redirection of biliopancreatic secretions on intestinal remodeling were investigated in RYGB operated rats. Methods RYGB employing two different Roux Limb (RL) lengths was performed on high fat diet induced obese rats. Post-operatively, rats were fed either Solid or isocaloric Liquid diets. Metabolic and morphological remodeling of intestine was compared across both diet forms (Solid and Liquid diets) and surgical models (Short RL and Long RL). Results RYGB surgery in rats induced weight loss and improved glucose tolerance which was independent of physical properties of ingested food and biliopancreatic secretions. Intestinal glucose utilization after RYGB was not determined by either food form or biliopancreatic secretions. The GLUT-1 expression in RL was not influenced by physical properties of food. Furthermore, both physical properties of food and biliopancreatic secretions showed no effects on intestinal morphological adaptations after RYGB. Conclusion Results of this study demonstrate that physical properties of food and bile redirection are not major determinants of intestinal remodeling after RYGB in rats.

Reduction of Plasma BCAAs following Roux-en-Y Gastric Bypass Surgery Is Primarily Mediated by FGF21. Nutrients 2023; 15:1713. [PMID: 37049555 PMCID: PMC10096671 DOI: 10.3390/nu15071713] [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: 02/24/2023] [Revised: 03/26/2023] [Accepted: 03/30/2023] [Indexed: 04/03/2023] Open
Abstract
Type 2 diabetes (T2D) is a challenging health concern worldwide. A lifestyle intervention to treat T2D is difficult to adhere, and the effectiveness of approved medications such as metformin, thiazolidinediones (TZDs), and sulfonylureas are suboptimal. On the other hand, bariatric procedures such as Roux-en-Y gastric bypass (RYGB) are being recognized for their remarkable ability to achieve diabetes remission, although the underlying mechanism is not clear. Recent evidence points to branched-chain amino acids (BCAAs) as a potential contributor to glucose impairment and insulin resistance. RYGB has been shown to effectively lower plasma BCAAs in insulin-resistant or T2D patients that may help improve glycemic control, but the underlying mechanism for BCAA reduction is not understood. Hence, we attempted to explore the mechanism by which RYGB reduces BCAAs. To this end, we randomized diet-induced obese (DIO) mice into three groups that underwent either sham or RYGB surgery or food restriction to match the weight of RYGB mice. We also included regular chow-diet-fed healthy mice as an additional control group. Here, we show that compared to sham surgery, RYGB in DIO mice markedly lowered serum BCAAs most likely by rescuing BCAA breakdown in both liver and white adipose tissues. Importantly, the restored BCAA metabolism following RYGB was independent of caloric intake. Fasting insulin and HOMA-IR were decreased as expected, and serum valine was strongly associated with insulin resistance. While gut hormones such as glucagon-like peptide-1 (GLP-1) and peptide YY (PYY) are postulated to mediate various surgery-induced metabolic benefits, mice lacking these hormonal signals (GLP-1R/Y2R double KO) were still able to effectively lower plasma BCAAs and improve glucose tolerance, similar to mice with intact GLP-1 and PYY signaling. On the other hand, mice deficient in fibroblast growth factor 21 (FGF21), another candidate hormone implicated in enhanced glucoregulatory action following RYGB, failed to decrease plasma BCAAs and normalize hepatic BCAA degradation following surgery. This is the first study using an animal model to successfully recapitulate the RYGB-led reduction of circulating BCAAs observed in humans. Our findings unmasked a critical role of FGF21 in mediating the rescue of BCAA metabolism following surgery. It would be interesting to explore the possibility of whether RYGB-induced improvement in glucose homeostasis is partly through decreased BCAAs.

Does ASA classification effectively risk stratify patients undergoing bariatric surgery: a MBSAQIP retrospective cohort of 138,612 of patients. Surg Endosc 2023:10.1007/s00464-023-10017-w.

Abstract
INTRODUCTION It is important to appropriately risk stratify bariatric surgery patients, as these patients often have obesity-related comorbidities which can increase postoperative complication risk but also benefit the most from bariatric surgery. We aimed to evaluate the utility of risk stratification using ASA class for bariatric surgery patients and assessed predictive factors of postoperative complications. METHODS The 2020 MBSAQIP database was analyzed, and an ASA-deemed high-risk cohort (class IV) and normal-risk (ASA class II and III) cohort were compared. Univariate analysis was performed to characterize differences between cohorts and to compare complication rates. Multivariate logistic regression analysis was performed to determine factors associated with increased odds of postoperative complications. RESULTS We evaluated 138 612 patients with 5380 (3.9%) considered high-risk and 133 232 (96.1%) normal-risk. High-risk patients were more likely to be older (46.2 ± 12.0vs.43.4 ± 11.9, p < 0.001), male (30.9%vs.18.4%, p < 0.001), have higher BMI (51.4 ± 10.2vs.44.9 ± 7.4, p < 0.001), and have more comorbidities. High-risk patients were more likely to have increased 30-day serious complications (4.5%vs.2.8%, p < 0.001) and death (0.2%vs.0.1%, p = 0.001) but not anastomotic leak (0.2%vs.0.2%, p = 0.983). Multivariate models showed ASA class IV patients were at higher odds for any serious complication by 30 days (aOR 1.36, 95%CI 1.18-1.56, p < 0.001) but not for death (aOR 1.04, 95%CI 0.49-2.21, p = 0.921). The factor independently associated with the highest odds of complication in both models was functional status preoperatively (partially dependent aOR 2.06, 95%CI 1.56-2.72, p < 0.001; fully dependent aOR 3.19, 95%CI 1.10-9.28, p = 0.033 for any serious complication; partially dependent aOR 5.08, 95%CI 2.16-12.00, p < 0.001 for death). CONCLUSIONS While elevated ASA class correlates with increased serious complications, pre-operative functional status appears to have a much greater contribution to odds of serious complications and mortality. These findings question the utility of using ASA to risk stratify patients peri-operatively and provides evidence for using a simpler and more practical functional status approach.

Abstract
Bariatric surgery improves glucose homeostasis and glycemic control in patients with type 2 diabetes. Over the past 20 years, a breadth of studies has been conducted in humans and rodents aimed to identify the regulatory nodes responsible for surgical remission of type 2 diabetes. The review herein discusses central mechanisms of type 2 diabetes remission associated with weight loss and surgical modification of the gastrointestinal tract.

Abstract
Long-term remission of type 2 diabetes following lifestyle intervention or pharmacotherapy, even in patients with mild disease, is rare. Long-term remission following metabolic surgery however, is common and occurs in 23% to 98% depending on disease severity and type of surgery. Remission after surgery is associated with excellent glycemic control without reliance on pharmacotherapy, improvements in quality of life, and major reductions in microvascular and macrovascular complications. For patients with type 2 diabetes, early intervention with metabolic surgery, when beta cell function still remains intact, provides the greatest probability of long-term remission as high as 90% or more.

Abstract
OBJECTIVE This retrospective study incorporated long-term mortality results after different bariatric surgery procedures and for multiple age at surgery groups. METHODS Participants with bariatric surgery (surgery) and without (non-surgery) were matched (1:1) for age, sex, BMI, and surgery date with a driver license application/renewal date. Mortality rates were compared by Cox regression, stratified by sex, surgery type, and age at surgery. RESULTS Participants included 21,837 matched surgery and non-surgery pairs. Follow-up was up to 40 years (mean [SD], 13.2 [9.5] years). All-cause mortality was 16% lower in surgery compared with non-surgery groups (hazard ratio, 0.84; 95% CI: 0.79-0.90; p < 0.001). Significantly lower mortality after bariatric surgery was observed for both females and males. Mortality after surgery versus non-surgery decreased significantly by 29%, 43%, and 72% for cardiovascular disease, cancer, and diabetes, respectively. The hazard ratio for suicide was 2.4 times higher in surgery compared with non-surgery participants (95% CI: 1.57-3.68; p < 0.001), primarily in participants with ages at surgery between 18 and 34 years. CONCLUSIONS Reduced all-cause mortality was durable for multiple decades, for multiple bariatric surgical procedures, for females and males, and for greater than age 34 years at surgery. Rate of death from suicide was significantly higher in surgery versus non-surgery participants only in the youngest age at surgery participants.

Abstract
BACKGROUND This study evaluated temporal association of changes in BMI over time with major adverse cardiovascular event (MACE) in Korean middle-aged adults. METHODS Between 2001 and 2002, 6855 individuals from the Korean Genome and Epidemiology Study were included and followed up until 2014. The main predictor was the change in BMI determined using group-based trajectory modelling (decreasing, stable, and increasing) from the baseline to 4-, 6-, and 8-years of follow-up. The primary outcome was the occurrence of MACE. RESULTS During the mean 10.2 years follow-up, MACEs occurred in 350 (5.1 %) individuals. The median (interquartile rage) age of study population was 50 (44-59) years. In primary analysis with 4-year trajectory model, decreasing BMI trajectory was associated with a 1.41-fold higher risk of the MACEs (hazard ratio [HR], 1.41; 95 % confidence interval [CI], 1.06-1.91) compared with stable BMI trajectory. In secondary analyses with 6- and 8-year trajectory models, this association disappeared, and the corresponding HRs (95 % CIs) were 1.14 (0.81-1.61) and 0.98 (0.65-1.49), respectively. There were concomitant improvements in cardiometabolic risk factors in decreasing BMI group, but unfavorable risk burden remained up to 4 to 6 years. CONCLUSIONS The initial 4-year weight loss was paradoxically associated with a higher risk of MACEs, probably due to residual cardiovascular burden. However, this association became null in participants with sustained weight loss ≥ 6 years, suggesting a possible lag effect of weight loss on MACEs.

Abstract
Diabetes mellitus is a prevalent, life-threatening, and costly medical illness. Type 2 diabetes is defined by insulin resistance caused by persistent hyperglycemia, and it is frequently diagnosed by tests such as fasting blood glucose levels of more than 7.0 mmol/L or HbA1c values of more than 6.5%. Pathogenesis and development of type 2 diabetes mellitus are clearly varied, with genetic and environmental factors both leading to it. The attainment of glycated hemoglobin (HbA1c) levels below the diagnostic level and maintaining it for a minimum of six months without pharmacotherapy, is described as diabetes remission. Diagnosis is a two-part procedure. To begin, the diagnosis of diabetes must be confirmed, and then the type of diabetes must be determined. Even in patients who succeeded to maintain remission, follow-up with the physician and regular tests should be done to prevent any expected diabetes complications.

Abstract
PURPOSE To compare the efficacy of OADS and SG in treating obese T2D in China. MATERIALS AND METHODS We included 99 obese Chinese patients with T2D undergoing OADS or SG with a 1-year postoperative follow-up from January 2014 to October 2021. Using the propensity score matching (PSM) method, patients from both groups were matched 1:1. Outcomes for losing weight, controlling diabetes, and nutrition were then determined. RESULTS There were 32 patients in each group after using the PSM method, and there was no statistically significant difference between the two groups in terms of all the baseline indicators (P > 0.05). When comparing weight loss outcomes, the OADS group outperformed the SG group in terms of change in BMI and %TWL, with statistically significant differences [15.0 (8.1-26.6) kg/m2, 10.0 (4.10-23.5) kg/m2 P = 0.001; 38.5% ± 6.7%, 29.5% ± 9.4%, P = 0.000]. When comparing the efficacy of diabetes, the OADS group outperformed the SG group in terms of HbA1C and complete remission of diabetes, with statistically significant differences [5.1 (3.8-5.6)%, 5.4 (4.3-7.9)%, P = 0.001; 100%, 75%, P = 0.005]. Besides, the incidence of postoperative zinc deficiency in the OADS group was significantly higher than in the SG group (P = 0.019) and there was no significant difference in other postoperative nutritional outcomes between the two groups. CONCLUSION Although OADS and SG are both effective in the treatment of obese T2D, OADS performs better. Besides, the long-term efficacy of both needs to be recorded at subsequent follow-up.

Effect of high-risk factors on postoperative major adverse cardiovascular and cerebrovascular events trends following bariatric surgery in the United States from 2012 to 2019. Surg Obes Relat Dis 2023; 19:59-67. [PMID: 36209030 DOI: 10.1016/j.soard.2022.08.014] [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: 06/30/2022] [Revised: 08/26/2022] [Accepted: 08/30/2022] [Indexed: 01/12/2023]
Abstract
BACKGROUND Recent examination of trends in postoperative major adverse cardiovascular and cerebrovascular events (MACE) following bariatric surgery, including accredited and nonaccredited centers, and the factors affecting those trends, is lacking. OBJECTIVES The objective of this study was to evaluate current trends for postoperative MACE after bariatric surgery in both accredited and nonaccredited centers and the factors affecting these trends. SETTING This retrospective study was conducted using National Inpatient Sample database from 2012 to 2019. METHODS All patients who underwent inpatient laparoscopic sleeve gastrectomy (LSG), open sleeve gastrectomy (SG), laparoscopic Roux-en-Y gastric bypass (LRYGB), and open Roux-en-Y gastric bypass (RYGB) were examined. Composite MACE (acute myocardial infarction, cardiac arrest, acute stroke, and in-hospital death during bariatric surgery hospitalization) was calculated and analyzed over time along with patient demographic and co-morbid diseases using survey-weighted logistic regression. RESULTS MACE incidence was lowest for LSG (0.07%), followed by LRYGB (0.16%), SG (3.47%), and RYBG (3.51%). Open procedure, increasing age, male sex, body mass index ≥50, coronary artery disease, congestive heart failure, and chronic kidney disease were independent predictors for increased MACE risk. MACE incidence increased over time for SG (odds ratio [OR] 1.25 [1.16, 1.34]; P < .0001) and RYGB (OR 1.14 [1.06, 1.22]; P = .0004) but decreased for LRYGB (OR 0.93 [0.87, 1] P = .06). After adjustment for high-risk covariates, increased MACE trend seen over time was attenuated in SG (OR 1.13 [1.04-1.22]; P = .005) and RYGB (OR 1.04 [0.96-1.12]; P = .36), while there was minimal effect of these high-risk covariates on MACE trend over time in LSG and LRYGB. CONCLUSIONS MACE following LSG and LRYGB is rare, occurring in 0.1% of patients. Persistently increasing high-risk conditions and demographics has had minimal effect on MACE over time for LSG and LRYGB but has had significant effect on MACE trend over time in SG and RYGB.

Gastric bypass versus best medical treatment for diabetic kidney disease: 5 years follow up of a single-centre open label randomised controlled trial. EClinicalMedicine 2022; 53:101725. [PMID: 36467457 PMCID: PMC9716325 DOI: 10.1016/j.eclinm.2022.101725] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/10/2022] [Revised: 10/10/2022] [Accepted: 10/12/2022] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND We compared the albuminuria-lowering effects of Roux-en-Y gastric bypass (RYGB) to best medical treatment in patients with diabetic kidney disease and obesity to determine which treatment is better. METHODS A 5 year, open-label, single-centre, randomised trial studied patients with diabetic kidney disease and class I obesity after 1:1 randomization to best medical treatment (n = 49) or RYGB (n = 51). The primary outcome was the proportion of patients achieving remission of microalbuminuria after 5 years. Secondary outcomes included improvements in diabetic kidney disease, glycemic control, quality of life, and safety. For efficacy outcomes, we performed an intention-to-treat (ITT) analysis. This study was registered with ClinicalTrials.gov, NCT01821508. FINDINGS 88% of patients (44 per arm) completed 5-year follow-up. Remission of albuminuria occurred in 59.6% (95% CI = 45.5-73.8) after best medical treatment and 69.7% (95% CI = 59.6-79.8) after RYGB (risk difference: 10%, 95% CI, -7 to 27, P = 0.25). Patients after RYGB were twice as likely to achieve an HbA1c ≤ 6.5% (60.2% versus 25.4%, risk difference, 34.9%; 95% CI = 15.8-53.9, P < 0.001). Quality of life after five years measured by the 36-Item Short Form Survey questionnaire (standardized to a 0-to-100 scale) was higher in the RYGB group than in the best medical treatment group for several domains. The mean differences were 13.5 (95% CI, 5.5-21.6, P = 0.001) for general health, 19.7 (95% CI, 9.1-30.3, P < 0.001) for pain, 6.1 (95% CI, -4.8 to 17.0, P = 0.27) for social functioning, 8.3 (95% CI, 0.23 to 16.3, P = 0.04) for emotional well-being, 12.2 (95% CI, 3.9-20.4, P = 0.004) for vitality, 16.8 (95% CI, -0.75 to 34.4, P = 0.06) for mental health, 21.8 (95% CI, 4.8-38.7, P = 0.01) for physical health and 11.1 (95% CI, 2.24-19.9, P = 0.01) for physical functioning. Serious adverse events were experienced in 7/46 (15.2%) after best medical treatment and 11/46 patients (24%) after RYGB (P = 0.80). INTERPRETATION Albuminuria remission was not statistically different between best medical treatment and RYGB after 5 years in participants with diabetic kidney disease and class 1 obesity, with 6-7 in ten patients achieving remission of microalbuminuria (uACR <30 mg/g) in both groups. RYGB was superior in improving glycemia, diastolic blood pressure, lipids, body weight, and quality of life. FUNDING The study was supported by research grants from Johnson & Johnson Brasil, Oswaldo Cruz German Hospital, and by grant 12/YI/B2480 from Science Foundation Ireland (Dr le Roux) and grant 2015-02733 from the Swedish Medical Research Council (Dr le Roux).

Distal gastric bypass revision for weight recurrence or nonresponse to primary procedure: initial experience and outcomes in an academic practice. Surg Endosc 2022:10.1007/s00464-022-09719-4. [PMID: 36261645 DOI: 10.1007/s00464-022-09719-4] [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: 05/12/2022] [Accepted: 10/11/2022] [Indexed: 10/24/2022]
Abstract
BACKGROUND Considerable weight recurrence (WR) after Roux-en-Y gastric bypass (RYGB) may occur in nearly 20% of patients. While several nonoperative, endoscopic, and surgical interventions exist for this population, the optimal approach is unknown. This study reports our initial experience with distal bypass revision (DGB) and provides a comparison with patients after primary RYGB. METHODS Single-institution, retrospective review was conducted for patients who underwent DGB from 2018 to 2020. A Roux and common channel of 150 cm each were constructed (total alimentary limb 300 cm). A group of primary RYGB patients with similar demographics were selected as controls. Demographics, comorbidity resolution, surgical technique, complications, excess weight loss (EWL), total weight loss (TWL), BMI, and weight change data were compared. Patient postoperative weight loss (WL) was also compared after their primary and DGB operations. RESULTS Sixteen DGB patients, all female, were compared with 29 controls. DGB was performed on average 12.3 years after primary RYGB. In the DGB group, mean BMI was 53.7 before primary RYGB, 31.9 at nadir, and 44.1 prior to DGB. Post-DGB, mean BMI was 40.5, 37.4, 34.8, and 34.4, at 3-, 6-, 12-, and 24-months, respectively. Five patients (31.3%) experienced complications and were readmitted within 30 days, with two of them (12.5%) requiring reintervention and one (6.3%) undergoing reoperation. Mean EWL and TWL up to 2 years after DGB were lower than that after the patient's original RYGB (52.3 ± 18.6 vs. 67.2 ± 33.2; p = 0.126 and 19.6 ± 13.3 vs. 29.6 ± 11.8; p = 0.027, respectively). CONCLUSIONS DGB resulted in excellent WL up to 2 years after surgery but was associated with considerable postoperative complication rates. The magnitude of TWL was lower compared with the primary operation. Only a few patients experienced nutritional complications. Results of this study can help counsel patients pursuing DGB for WR or nonresponse to primary RYGB. The comparative effectiveness of this approach to other available options remains to be determined.

Abstract
Background Cardiovascular risk due to obesity can be improved greatly by bariatric surgery. However, there is no research involving appropriate model for evaluating cardiovascular disease risk reduction in bariatric surgery for obesity in China. We selected the ischemic cardiovascular disease (ICVD) risk score that accurately predict cardiovascular risk in Chinese adults to evaluate the 10-year risk of ICVD and estimated early cardiovascular benefits of bariatric surgery in obese Chinese patients through its reduction. Methods From 2017 to 2019 we followed up 107 patients 6 months after surgery and measured the ICVD 10-year risk and other cardiovascular factors before and after surgery. Results There were significant reductions in the ICVD total score (p < 0.001) and ICVD 10-year risk (%) (p < 0.001) 6 months post-operation compared with baseline. Furthermore, we found significant reductions in body mass index (BMI), body adiposity index (BAI), low-density lipoprotein (LDL), small dense-low-density lipoprotein (sd-LDL) and triglycerides (TG) 6 months after surgery compared with pre-operation (all p < 0.05). The decrease in ICVD total score was correlated with excess BMI loss (%EBMIL), reduced BAI, reduced LDL, reduced sd-LDL and reduced TG respectively (all p < 0.05) at 6 months post-operation. Moreover, there were significant reductions in the ICVD total score in the male subgroup [3 (3, 5) vs. 2.5 (2, 4), p < 0.001] and female subgroup [3 (2, 4) vs. 2 (1, 3), p < 0.001] 6 months post-operation compared with baseline. At last there were also significant reductions in the ICVD total score in the diabetic subgroup [5 (4, 6) vs. 4 (3, 5), p < 0.001] and non-diabetic subgroup [2 (2,3) vs. 2 (1, 2), p < 0.001] 6 months post-operation compared with baseline. Conclusions Bariatric surgery could provide early cardiovascular benefits for patients with obesity in China by reducing the 10-year risk of ICVD. Both men and women with obesity achieved cardiovascular benefits according to bariatric surgery, so did diabetic and non-diabetic patients.

Abstract
Abstract
Introduction: This study aims to compare the predictive capacity of ABCD, DiaRem2, Ad-DiaRem, and DiaBetter scoring systems for type 2 diabetes mellitus (T2DM) remission in Turkish adult morbidly obese patients who underwent SG.
Methods: This retrospective cohort study included 80 patients who underwent sleeve gastrectomy (SG) operation, were diagnosed with T2DM preoperatively, and had at least one-year follow-up after surgery. Because bariatric surgery is performed on patients with class III obesity (BMI ≥ 40 kg/m2) or class II obesity (BMI ≥ 35 kg/m2) with obesity releated comorbid conditions in our hospital, our study cohort consisted of these patients.
Results: The diagnostic performance of the DiaBetter, DiaRem2, Ad-DiaRem and ABCD for identifying diabetes remission, assessed by the AUC was 0.882 (95% CI, 0.807-0.958, p < 0.001), 0.862 (95% CI, 0.779-0.945, p < 0.001), 0.849 (95% CI, 0.766-0.932, p < 0.001) and 0.726 (95% CI, 0.601-0.851, p = 0.002), respectively. The AUCs of the Ad-Diarem, DiaBetter and DiaRem2 were statistically higher than AUC of the ABCD (all p-value < 0.001). Besides, there was no statistically significant difference in AUCs of the Ad-Diarem, DiaBetter and DiaRem scores (all p-value > 0.05).
Conclusion: Ad-Dairem, DiaBetter and DaiRem scoring systems were found to provide a successful prediction for diabetes remission in sleeve gastrectomy patients. It was observed that the predictive power of the ABCD scoring system was lower than the other systems. We think that the use of scoring systems for diabetes remission, which have a simple use, will become widespread.

Abstract
BACKGROUND Roux-en-Y gastric bypass (RYGB) is a gold-standard procedure for treatment of obesity and associated comorbidities. No consensus on the optimal design of this operation has been achieved, with various lengths of bypassed small bowel limb lengths being used by bariatric surgeons. This aim of this systematic review and meta-analysis was to determine whether biliopancreatic limb (BPL) length in RYGB affects postoperative outcomes including superior reduction in weight, body mass index (BMI), and resolution of metabolic comorbidities associated with obesity. METHODS A systematic search of the literature was conducted up until 1st June 2021. Meta-analysis of primary outcomes was performed utilising a random-effects model. Statistical significance was determined by p value < 0.05. RESULTS Ten randomised controlled trials were included in the final quantitative analysis. No difference in outcomes following short versus long BLP in RYGB was identified at 12-72 months post-operatively, namely in BMI reduction, remission or improvement of type 2 diabetes mellitus, hypertension, dyslipidaemia, and complications (p > 0.05). Even though results of four studies showed superior total body weight loss in the long BPL cohorts at 24 months post-operatively (pooled mean difference -6.92, 95% CI -12.37, -1.48, p = 0.01), this outcome was not observed at any other timepoint. CONCLUSION Based on the outcomes of the present study, there is no definitive evidence to suggest that alteration of the BPL affects the quantity of weight loss or resolution of co-existent metabolic comorbidities associated with obesity.

Abstract
INTRODUCTION Bariatric surgery is an effective method of controlling glycaemia in patients with type 2 diabetes mellitus (T2DM) and obesity. Long-term studies suggest that although glycaemic control remains good, only 20%-40% of patients will maintain remission according to the American Diabetes Association criteria. PURPOSE This trial aims to examine the safety and efficacy of combining Roux-en-Y gastric bypass or sleeve gastrectomy with goal-directed medical therapy to improve long-term glycaemic control of T2DM. METHODS AND ANALYSIS This prospective, open-label multicentre randomised controlled trial (RCT) will recruit 150 patients with obesity and T2DM from tertiary care obesity centres. Patients will be randomised 1:1 to receive either bariatric surgery and standard medical care or bariatric surgery and intensive goal-directed medical therapy, titrated to specific targets for glycated haemoglobin (HbA1c), blood pressure (BP) and low-density lipoproteins (LDL) cholesterol. The primary endpoints are the proportion of patients in each arm with an HbA1c<6.5% (48 mmol/mol) at 1 year and the proportion of patients in each arm achieving the composite endpoint of HbA1c<6.5% (48 mmol/mol), BP<130/80 mm Hg and LDL<2.6 mmol/L at 5 years. ETHICS AND DISSEMINATION The local institutional review board approved this study. This study represents the first RCT to examine the safety and efficacy of combining bariatric surgery with intensive medical therapy compared with bariatric surgery and usual care for long-term diabetes control. TRIAL REGISTRATION NUMBER NCT04432025.

Abstract
Background: The liver has the capacity to regulate glucose metabolism by altering the insulin clearance rate (ICR). The decreased fasting insulin concentrations and enhanced prandial hyperinsulinemia after Roux-en-Y gastric-bypass (GB) surgery and sleeve gastrectomy (SG) are well documented. Here, we investigated the effect of GB or SG on insulin kinetics in the fasting and fed states. Method: ICR was measured (i) during a mixed-meal test (MMT) in obese non-diabetic GB (n = 9) and SG (n = 7) subjects and (ii) during a MMT combined with a hyperinsulinemic hypoglycemic clamp in the same GB and SG subjects. Five BMI-matched and non-diabetic subjects served as age-matched non-operated controls (CN). Results: The enhanced ICR during the fasting state after GB and SC compared with CN (p < 0.05) was mainly attributed to augmented hepatic insulin clearance rather than non-liver organs. The dose-response slope of the total insulin extraction rate (InsExt) of exogenous insulin per circulatory insulin value was greater in the GB and SG subjects than in the CN subjects, despite the similar peripheral insulin sensitivity among the three groups. Compared to the SG or the CN subjects, the GB subjects had greater prandial insulin secretion (ISR), independent of glycemic levels. The larger post-meal ISR following GB compared with SG was associated with a greater InsExt until it reached a plateau, leading to a similar reduction in meal-induced ICR among the GB and SG subjects. Conclusions: GB and SG alter ICR in the presence or absence of meal stimulus. Further, altered ICR after bariatric surgery results from changes in hepatic insulin clearance and not from a change in peripheral insulin sensitivity.

Experience of the First 100 OAGB in China: OAGB In Situ Technique. Obes Surg 2022; 32:2945-2951. [PMID: 35790674 PMCID: PMC9256529 DOI: 10.1007/s11695-022-05966-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/25/2021] [Revised: 02/04/2022] [Accepted: 02/07/2022] [Indexed: 11/21/2022]
Abstract
Background One anastomosis gastric bypass (OAGB) is gradually accepted worldwide but still new in China. Materials and Methods Retrospective review of the patients who received OAGB in a new bariatric/metabolic surgical center in China and compared the data with a center of excellence in Taiwan. All in-patient and outpatient follow-up data were analyzed. The main outcome measures were (1) operation risk (2) weight loss (3) diabetes remission. Results Between August 2019 and October 2021, 100 consecutive patients who received OAGB in situ in China and 225 patients who received OAGB with the same technique were recruited from Taiwan. Taiwan patients were older (39.2 ± 10.6 vs. 33.3 ± 8.8 years old, p < 0.001), and to have more diabetes (32.4% vs. 20.0%, p = 0.022) comparing to the patients of China. Operation time was significantly longer for Taiwan patients (172.4 ± 36.9 vs. 128.5 ± 29.8, p < 0.001). Taiwan patients lost more blood during the operation (35.5 ± 25.2 vs. 22.4 ± 15.6, p < 0.001) but patients in China need more time to postoperative flatus passage (1.3 ± 0.5 vs. 2.0 ± 0.5, p < 0.001). There was no major surgical complication in this study, minor complication rates were similar low for both groups (1.0% vs. 1.8%, p = 0.891). At 1 year after surgery, %TWL and %EWL of both centers were similar (33.9 ± 7.43% vs. 32.6 ± 11.2%, p = 0.91; 81.9 vs. 19.8 vs. 85.4 ± 13.2, p = 0.798). T2DM remission (HbA1c < 6.5%) was 100% for patients of China and 95.9% for patients of Taiwan (p = 0.836). Conclusions OAGB in situ is a safe and effective bariatric/metabolic surgery. With proper training and proctorship, these results are reproduceable in a new bariatric/metabolic surgical center in China. Graphical abstract ![]()

Abstract
Obesity is a critical risk factor of several life-threatening diseases and the prevalence in adults has dramatically increased over the past ten years. In the USA the age-adjusted prevalence of obesity in adults was 42.4%, i.e., with a body mass index (BMI, weight (kg)/height (m)2) that exceeds 30 kg/m2. Obese individuals are at the higher risk of obesity-related diseases, co-morbid conditions, lower quality of life, and increased mortality more than those in the normal BMI range i.e., 18.5–24.9 kg/m2. Surgical treatment continues to be the most efficient and scientifically successful treatment for obese patients. Sleeve gastrectomy or vertical sleeve gastrectomy (VSG) is a relatively new gastric procedure to reduce body weight but is now the most popular bariatric operation. To date there have been few studies examining the changes in the cellular components and pacemaker activity that occur in the gastric wall following VSG and whether normal gastric activity recovers following VSG. In the present study we used a murine model to investigate the chronological changes of gastric excitability including electrophysiological, molecular and morphological changes in the gastric musculature following VSG. There is a significant disruption in specialized interstitial cells of Cajal in the gastric antrum following sleeve gastrectomy. This is associated with a loss of gastric pacemaker activity and post-junctional neuroeffector responses. Over a 4-month recovery period there was a gradual return in interstitial cells of Cajal networks, pacemaker activity and neural responses. These data describe for the first time the changes in gastric interstitial cells of Cajal networks, pacemaker activity and neuroeffector responses and the time-dependent recovery of ICC networks and normalization of motor activity and neural responses following VSG.

Abstract
The obesity epidemic has caused a surge in the use of bariatric surgery. Although surgery-induced weight loss is an effective treatment of nonalcoholic fatty liver disease, it may precipitate severe hepatic complications under certain circumstances. Acute liver injury (ALI) and acute liver failure (ALF) following bariatric surgery have been reported in several case series. Although rare, ALI and ALF tend to emerge several months after bariatric surgery. If so, it can result in prolonged hospitalization, may necessitate liver transplantation, and in some cases prove fatal. However, little is known about the risk factors for developing ALI or ALF after bariatric surgery and the mechanisms of liver damage in this context are poorly defined. This review provides an account of the available data on ALI and ALF caused by bariatric surgery, with emphasis on potential injury mechanisms and the outcomes of liver transplantation for ALF after bariatric surgery.

Abstract
We aimed to determine the effects of different exercise types, duration, and onset after bariatric surgery (BS) on cardiometabolic risk factors (CMRFs). A systematic search was conducted up to July 2021. Eleven studies were identified (n = 618 participants). Overall, exercise induced reductions in systolic blood pressure (SBP; - 5.33 mmHg; 95%CI - 8.99, -1.66; p < 0.01). Combined exercises elicited reductions on SBP (- 7.18 mmHg; 95%CI - 12.42, - 1.94; p < 0.01) and triglycerides (- 17.56 mg/dL; 95%CI - 34.15, - 0.96; p = 0.04). SBP reductions were also observed on interventions starting > 6 months post-BS (- 7.71 mmHg; 95%CI - 13.12, - 2.31; p < 0.01), and on > 12-week protocols (- 5.78 mmHg; 95%CI - 9.91, - 1.66; p < 0.01). Overall exercise and particularly aerobic plus resistance protocols were an effective therapy to reduce CMRFs post-BS. Benefits were also observed with interventions starting > 6 months post-BS and with > 12-week duration. Trial registration: CRD42020161175 .

Abstract
Obesity is a chronic disease with increasing prevalence. It affects quality of life and renders those affected at increased risk of mortality. For people living with obesity, weight loss is one of the most important strategies to improve health outcomes and prevent or reverse obesity-related complications. In line with newly released clinical practice guidelines, weight loss targets for people living with obesity should be defined individually based on their clinical profile, and progress measured in the context of improvements in health outcomes, rather than weight loss alone. We outline current treatment options for clinically meaningful weight loss and briefly discuss pharmacological agents and devices under development. Numerous studies have shown that weight loss of ≥5% results in significant improvements in cardiometabolic risk factors associated with obesity; this degree of weight loss is also required for the approval of novel anti-obesity medications by the US Food and Drug Administration. However, some obesity-related comorbidities and complications, such as non-alcoholic steatohepatitis, obstructive sleep apnea, gastroesophageal reflux disease and remission of type 2 diabetes, require a greater magnitude of weight loss to achieve clinically meaningful improvements. In this review, we assessed the available literature describing the effect of categorical weight losses of ≥5%, ≥10%, and ≥15% on obesity-related comorbidities and complications, and challenge the concept of clinically meaningful weight loss to go beyond percentage change in total body weight. We discuss weight-loss interventions including lifestyle interventions and therapeutic options including devices, and pharmacological and surgical approaches as assessed from the available literature.

Abstract
A durable normoglycemic state was observed in several studies that treated type 2 diabetes mellitus (T2DM) patients through metabolic surgery, intensive therapeutic intervention, or significant lifestyle modification, and it was confirmed that the functional β-cell mass was also restored to a normal level. Therefore, expert consensus introduced the concept of remission as a common term to express this phenomenon in 2009. Throughout this article, we introduce the recently updated consensus statement on the remission of T2DM in 2021 and share our perspective on the remission of diabetes. There is a need for more research on remission in Korea as well as in Western countries. Remission appears to be prompted by proactive treatment for hyperglycemia and significant weight loss prior to irreversible β-cell changes. T2DM is not a diagnosis for vulnerable individuals to helplessly accept. We attempt to explain how remission of T2DM can be achieved through a personalized approach. It may be necessary to change the concept of T2DM towards that of an urgent condition that requires rapid intervention rather than a chronic, progressive disease. We must grasp this paradigm shift in our understanding of T2DM for the benefit of our patients as endocrine experts.

The early reduction of left ventricular mass after sleeve gastrectomy depends on the fall of branched-chain amino acid circulating levels. EBioMedicine 2022; 76:103864.

Abstract
Introduction Body-mass index is a major determinant of left-ventricular-mass (LVM). Bariatric-metabolic surgery (BMS) reduces cardiovascular mortality. Its mechanism of action, however, often encompasses a weight-dependent effect. In this translational study, we aimed at investigating the mechanisms by which BMS leads to LVM reduction and functional improvement. Methods Twenty patients (45.2 ± 8.5years) were studied with echocardiography at baseline and at 1,6,12 and 48 months after sleeve-gastrectomy (SG). Ten Wistar rats aged 10-weeks received high-fat diet ad libitum for 10 weeks before and 4 weeks after SG or sham-operation. An oral-glucose-tolerance-test was performed to measure whole-body insulin-sensitivity. Plasma metabolomics was analysed in both human and rodent samples. RNA quantitative Real-Time PCR and western blots were performed in rodent heart biopsies. The best-fitted partial-least-square discriminant-analysis model was used to explore the variable importance in the projection score of all metabolites. Findings Echocardiographic LVM (-12%,-23%,-28% and -43% at 1,6,12 and 48 months, respectively) and epicardial fat decreased overtime after SG in humans while insulin-sensitivity improved. In rats, SG significantly reduced LVM and epicardial fat, enhanced ejection-fraction and improved insulin-sensitivity compared to sham-operation. Metabolomics showed a progressive decline of plasma branched-chain amino-acids (BCAA), alanine, lactate, 3-OH-butyrate, acetoacetate, creatine and creatinine levels in both humans and rodents. Hearts of SG rats had a more efficient BCAA, glucose and fatty-acid metabolism and insulin signaling than sham-operation. BCAAs in cardiomyocyte culture-medium stimulated lipogenic gene transcription and reduced mRNA levels of key mitochondrial β-oxidation enzymes promoting lipid droplet accumulation and glycolysis. Interpretation After SG a prompt and sustained decrease of the LVM, epicardial fat and insulin resistance was found. Animal and in vitro studies showed that SG improves cardiac BCAA metabolism with consequent amelioration of fat oxidation and insulin signaling translating into decreased intra-myocytic fat accumulation and reduced lipotoxicity.

Abstract
Background: The increased prevalence of obesity has led to a significant increase in the occurrence of metabolic syndrome, a recognized risk factor for increased morbidity and mortality from cardiovascular diseases. Hyperglycemia or type 2 diabetes mellitus, dyslipidemia and arterial hypertension are its main components. Since 2015, international guidelines have recognized the benefits of bariatric surgery in each isolated factor of this syndrome.
Aim: To evaluate the impact of Roux-en-Y gastric bypass in this syndrome comparing pre- and postoperative periods with laboratory analysis and to compare waist/height ratio and BMI in relation to the determination of the cardiometabolic risk profile.
Methods: A retrospective study was carried out, selecting 80 patients undergoing Roux-en-Y gastric bypass. Total cholesterol, HDL, LDL, triglycerides, fasting glucose, glycated hemoglobin, insulin, body mass index (BMI), vitamin D, vitamin B12, waist circumference and waist/height ratio in three periods were analyzed: the preoperative period from 1 to 6 months, postoperative from 1 to 6 months and postoperative from 1 to 2 years.
Results: There was an improvement in all parameters of the clinical analyses. The preoperative BMI had a mean value of 39.8, in the preoperative period from 1 to 6 months, the values dropped to 33.2 and in the postoperative period of 1 year, the mean was 26. The perimeter mean values of 118.5 preoperatively, 105.2 postoperatively from 1 to 6 months and 90.3 postoperatively from 1 to 2 years. Waist/height ratio was 0.73, 0.65 and 0.56 in pre, post 1 to 6 months and 1 to 2 years respectively.
Conclusion: Roux-en-Y gastric bypass improves metabolic syndrome and waist-to-height ratio is superior to BMI in the assessment of the cardiometabolic risk profile.

Abstract
Pancreatic β cells secrete insulin in response to glucose, a process that is regulated at multiple levels, including a network of input signals from other organ systems. Impaired islet function contributes to the pathogenesis of type 2 diabetes mellitus (T2DM), and targeting inter-organ communications, such as GLP-1 signalling, to enhance β-cell function has been proven to be a successful therapeutic strategy in the last decade. In this review, we will discuss recent advances in inter-organ communication from the metabolic, immune and neural system to pancreatic islets, their biological implication in normal pancreas endocrine function and their role in the (mal)adaptive responses of islet to nutrition-induced stress.

Abstract
INTRODUCTION The prevalence of obesity has increased exponentially in recent decades, being one of the diseases that most affects global health. It is a chronic disease associated with multiple comorbidities, which lead to a decrease in life expectancy and quality of life. It requires a multidisciplinary approach by a specialized medical team. Obesity can be treated with conservative or with surgical treatments that will depend on the characteristics of the patient. OBJECTIVE/METHODOLOGY The referenced surgery can be performed using different surgical techniques that are analyzed in the present work through an exhaustive narrative bibliographic review in the PubMed and Cochrane databases, as well as in UpToDate. RESULTS Currently, those most used are restrictive techniques, specifically vertical gastrectomy and mixed techniques, with gastric bypass being the "gold standard". CONCLUSIONS In order to choose one technique or another, the characteristics of each patient and the experience of the surgical team must be taken into account.

Abstract
AIMS/INTRODUCTION To compare glycemic control 1 year after treatment in patients with mildly obese (body mass index 27.5-34.9 kg/m2 ) type 2 diabetes mellitus who underwent bariatric surgery (BS) to those who received medical treatment (MT) in Japan. MATERIALS AND METHODS A retrospective study using real-world data was carried out in electronic medical records from a tertiary care hospital and in the Japanese Medical Data Center Inc. claim database from 2008 to 2019. Each patient was propensity score-matched between the BS and the MT group by age, sex, body mass index, glycated hemoglobin and type 2 diabetes mellitus duration, and compared from the index date to the 1 year post-index. RESULTS The study included 78 patients in the BS group and 238 patients in the MT group. The mean body mass index in the BS and the MT group was 32.1 and 32.0 kg/m2 , respectively. In the BS group, the patients underwent either laparoscopic sleeve gastrectomy with or without duodenojejunal bypass. The diabetes remission rate (glycated hemoglobin <6.5% without diabetes medication) at 1 year was 59.0% in the BS group and 0.4% in the MT group (P < 0.0001). Optimal glycemic control of glycated hemoglobin <7.0% was achieved in 75.6% in the BS group and in 29.0% in the MT group (P < 0.0001). The median monthly drug costs for metabolic syndrome decreased from $US126.5 (at baseline) to $US0.0 (at 1 year) in the BS group, whereas it increased from $US52.4 to $US58.3 in the MT group. CONCLUSIONS BS for mildly obese patients with type 2 diabetes mellitus is more clinically- and cost-effective than MT in Japan.

Ann Surg 2022; 275:e181-e188.

Abstract
OBJECTIVE To characterize system-level barriers to bariatric surgery from the perspectives of Veterans with severe obesity and obesity care providers. SUMMARY OF BACKGROUND DATA Bariatric surgery is the most effective weight loss option for Veterans with severe obesity, but fewer than 0.1% of Veterans with severe obesity undergo it. Addressing low utilization of bariatric surgery and weight management services is a priority for the veterans health administration. METHODS We conducted semi-structured interviews with Veterans with severe obesity who were referred for or underwent bariatric surgery, and providers who delivered care to veterans with severe obesity, including bariatric surgeons, primary care providers, registered dietitians, and health psychologists. We asked study participants to describe their experiences with the bariatric surgery delivery process in the VA system. All interviews were audio-recorded and transcribed. Four coders iteratively developed a codebook and used conventional content analysis to identify relevant systems or "contextual" barriers within Andersen Behavioral Model of Health Services Use. RESULTS Seventy-three semi-structured interviews with veterans (n = 33) and providers (n = 40) throughout the veterans health administration system were completed. More than three-fourths of Veterans were male, whereas nearly three-fourths of the providers were female. Eight themes were mapped onto Andersen model as barriers to bariatric surgery: poor care coordination, lack of bariatric surgery guidelines, limited primary care providers and referring provider knowledge about bariatric surgery, long travel distances, delayed referrals, limited access to healthy foods, difficulties meetings preoperative requirements, and lack of provider availability and/or time. CONCLUSIONS Addressing system-level barriers by improving coordination of care and standardizing some aspects of bariatric surgery care may improve access to evidence-based severe obesity care within VA.

A nonhuman primate model of vertical sleeve gastrectomy facilitates mechanistic and translational research in human obesity. iScience 2021; 24:103421.

Abstract
The obesity epidemic significantly contributes to overall morbidity and mortality. Bariatric surgery is the gold standard treatment for obesity and metabolic dysfunction, yet the mechanisms by which it exerts metabolic benefit remain unclear. Here, we demonstrate a model of vertical sleeve gastrectomy (VSG) in nonhuman primates (NHP) that mimics the complexity and outcomes in humans. We also show that VSG confers weight loss and durable metabolic benefit, where equivalent caloric intake in shams resulted in significant weight gain following surgery. Furthermore, we show that VSG is associated with early, weight-independent increases in bile acids, short-chain fatty acids, and reduced visceral adipose tissue (VAT) inflammation with a polarization of VAT-resident immunocytes toward highly regulatory myeloid cells and Tregs. These data demonstrate that this strongly translational NHP model can be used to interrogate factors driving successful intervention to unravel the interplay between physiologic systems and improve therapies for obesity and metabolic syndrome.
