Weight Loss Following Bariatric Surgery in People with or without Metabolic Syndrome: A 5-Year Observational Comparative Study. J Clin Med 2024; 13:256. [PMID: 38202263 PMCID: PMC10779877 DOI: 10.3390/jcm13010256] [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: 10/14/2023] [Revised: 12/28/2023] [Accepted: 12/29/2023] [Indexed: 01/12/2024] Open
Abstract
AIM Whilst bariatric surgery is the most effective treatment for severe obesity, the aim of this study was to evaluate whether postoperative weight loss is similar in patients with or without metabolic syndrome. METHODS We performed a 5-year observational retrospective comparative cohort analysis of bariatric surgery in 333 patients (72% women) without (Group A, n = 133) or with (Group B, n = 200) metabolic syndrome at baseline. RESULTS Overall mean (SD) baseline body mass index was 51.7 (7.5) with no significant difference between groups. Overall mean percent total weight loss (%TWL) was 31.9% by 24 months after surgery. Although %TWL was greater in Group A (34.9%) than in Group B (30.2%, p = 0.006) at 24 months, there were no significant differences between groups subsequently up to 60 months of follow-up. Systolic and diastolic blood pressures and lipid profiles improved in both groups. In patients with metabolic syndrome at baseline, mean HbA1c reduced by 36.4% at 12 months and was sustained over the study period. CONCLUSIONS We report that bariatric surgery results in comparable long-term weight loss in patients with or without metabolic syndrome alongside expected improvements in metabolic comorbidities.

Abstract
BACKGROUND Bariatric surgery is a proven effective method of reducing obesity and reversing or preventing obesity-related comorbidities. The aim of this study is to describe the development of a tool to assist with the prioritization of patients with obesity for bariatric surgery. The tool would meet the criteria for being evidence-based, fair, implementable and transparent. METHODS The development of the tool involved a validated step-by-step process based on the consensus of clinical judgement of the New Zealand Ministry of Health working party. The process involved elicitation of criteria, clinical ranking of vignettes and creation of weightings using the 1000Minds® tool. The concurrent validity was tested by comparing tool rankings of vignettes to clinical judgement rankings. RESULTS Four major criteria (impact on life, likelihood of achieving maximum benefit with respect to control of diabetes, duration of benefit and surgical risk) are used to characterize the need and potential to benefit. The impact on life criterion has the largest weighting (up to 44.3%). There was good concurrent validity with a correlation coefficient r = 0.67. CONCLUSION The tool as presented is evidence-based, transparent and internally valid. The next step is to assess the predictive validity of the tool using real patient data to evaluate the effectiveness of the tool and determine what modifications may be required.

Abstract
BACKGROUND Prior literature has demonstrated that bariatric surgery is a safe approach for patients with morbid obesity. However, the relationship between body mass index (BMI) and risk of mortality in these patients has not been fully elucidated. Primary objective of this study was to evaluate the relationship between BMI and risk of mortality using data obtained from a national database, with a special focus on patients with BMI ≥ 70.0 kg/m2. METHODS A retrospective cohort study of patients with morbid obesity (BMI ≥ 40 kg/m2) undergoing first-time bariatric surgery between 2015 and 2018 was performed using data from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program. Primary outcome was intra-operative death or death within 30 days post-operatively. Patients were categorized into quartiles according to BMI. Multivariable analysis was performed to evaluate the association of BMI with risk of mortality. Relative risk (RR) and 95% confidence interval (CI) are provided as measures of strength of association and precision, respectively. RESULTS A total of 463, 436 patients were included with a 30-day mortality rate of 0.11%. Mean BMI (SD) was 48.2 (7.3) kg/m2; 1.5% of patients had BMI ≥ 70.0 kg/m2. On multivariable analysis, highest quartile patients had a significantly higher risk of mortality than lowest quartile patients. For patients with BMI ≥ 70.0 kg/m2, the risk of mortality was more pronounced with an eightfold increase compared to the lowest quartile. In patients with BMI ≥ 70.0 kg/m2, although sleeve gastrectomy (SG) was the most common procedure, the risk of mortality was significantly higher in patients undergoing Roux-en-Y gastric bypass (RYGB). CONCLUSIONS BMI is associated with increased risk of 30-day mortality. The effect of BMI is more pronounced in patients with BMI ≥ 70.0 kg/m2. In these patients, RYGB is associated with increased risk of mortality compared to SG.

Use of Magnetic Resonance Imaging to Quantify Fat and Steatosis in the Pancreas in Patients after Bariatric Surgery: a Retrospective Study. Obes Surg 2022; 32:3666-3674. [PMID: 36121606 DOI: 10.1007/s11695-022-06278-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2022] [Revised: 09/08/2022] [Accepted: 09/12/2022] [Indexed: 11/26/2022]
Abstract
INTRODUCTION Pancreatic steatosis (PS) has both metabolic consequences and local effects on the pancreas itself. Magnetic resonance imaging (MRI) is the most reliable non-invasive method for diagnosing PS. We investigated the impact of metabolic syndrome (MS) on the presence of PS, differences in individuals with and without PS, and the metabolic effects of bariatric procedures. METHODS Changes in anthropometric and basic biochemistry values and MS occurrence were evaluated in 34 patients with obesity who underwent a bariatric procedure. After the procedure, patients underwent MRI with manual 3D segmentation mask creation to determine the pancreatic fat content (PFC). We compared the differences in the PFC and the presence of PS in individuals with and without MS and compared patients with and without PS. RESULTS We found no significant difference in the PFC between the groups with and without MS or in the occurrence of PS. There were significant differences in patients with and without PS, especially in body mass index (BMI), fat mass, visceral adipose tissue (VAT), select adipocytokines, and lipid spectrum with no difference in glycemia levels. Significant metabolic effects of bariatric procedures were observed. CONCLUSIONS Bariatric procedures can be considered effective in the treatment of obesity, MS, and some of its components. Measuring PFC using MRI did not show any difference in relation to MS, but patients who lost weight to BMI < 30 did not suffer from PS and had lower overall fat mass and VAT. Glycemia levels did not have an impact on the presence of PS.

Concordance between Different Criteria for Metabolic Syndrome in Peruvian Adults Undergoing Bariatric Surgery. J Clin Med 2022; 11:jcm11164692. [PMID: 36012930 PMCID: PMC9410096 DOI: 10.3390/jcm11164692] [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: 06/15/2022] [Revised: 07/21/2022] [Accepted: 07/28/2022] [Indexed: 11/16/2022] Open
Abstract
Background: Metabolic Syndrome (MetS) is a clinical entity that has been linked to several non-communicable diseases. There are various consensuses to determine its presence, such as the IDF, ALAD, Harmonized, AHA/NHLBI, NCEP-ATP III or AACE criteria. However, there is currently no standardization to properly identify it. Objective: To assess the diagnostic concordance between different criteria for MetS in Peruvian adults undergoing bariatric surgery. Methods: We conducted a secondary analysis of the institutional database of a bariatric clinic located in Lima, Peru. We obtained data from adults between 18–59 years who underwent bariatric surgery (Roux-en-Y Gastric Bypass or Sleeve Gastrectomy). According to the Kappa coefficient, a heatplot was designed to analyze the concordance of the criteria. Results: An almost perfect concordance was found between all criteria except AACE. The highest kappa coefficient (κ = 0.980) was recorded between the IDF and ALAD criteria using all the sample. Similar results were obtained when we stratified by sex. Conclusions: This study shows that, excluding the AACE, different criteria for metabolic syndrome could be used in Latino adults undergoing bariatric surgery with similar results. Given the postoperative implications, we believe that IDF and ALAD would be the best options in our population.

Abstract
This systematic review and meta-analysis intend to evaluate the efficacy of metabolic/bariatric surgeries (MBS) in patients with type-1 diabetes mellitus. A systematic literature search and meta-analysis were performed in electronic databases up to July 2021. In total, 27 primary studies comprising 648 subjects were included in this systematic review and meta-analysis. Patients had a mean age of 38.0 ± 7.3 years. Preoperative mean BMI was 42.6 ± 4.7 kg/m2 and 29.4 ± 4.7 kg/m2 after surgery, respectively. Following bariatric surgeries in patients with type 1 diabetes mellitus, insulin (unit/day) decreased by a weighted mean difference (WMD) of - 10.59. Also, insulin (unit/kg/day) decreased by a WMD of - 0.2, and HbA1C decreased by a WMD of - 0.71, showing MBS acceptable and durable effects of bariatric surgical procedures.

Abstract
PURPOSE The prevalence of metabolic syndrome (MetS) increases in parallel with the increasing incidence of obesity. Hence, bariatric surgery is potentially curative in obese patients with MetS. We aim to measure the effect of bariatric surgery as well as the potential factors leading to MetS resolution in the Saudi population. METHODS A retrospective review of three tertiary care centers in Saudi Arabia was done. We identified 386 patients who have MetS and underwent bariatric surgery during the period between January 2016 and December 2018. After exclusion of patients with insufficient follow-up, data from 275 patients was analyzed. MetS diagnosis, persistence, and resolution were determined using the International Diabetes Federation consensus worldwide definition. RESULTS MetS resolution was achieved in 78%, 79%, 73%, and 82% at 1, 2, 3, and 4 years after bariatric surgery, respectively. Accumulatively, 80% achieved MetS resolution with an average follow-up period of two and a half years. Patients who experienced resolution had younger age, lower BMI, lower systolic blood pressure, lower triglycerides, lower fasting plasma glucose, and lower HbA1c preoperatively in addition to a higher percentage of excess weight loss after bariatric surgery when compared to those who had persistence of MetS. CONCLUSION More than three fourths of patients with MetS achieved resolution after bariatric surgery. Certain patient characteristics, such as young age and higher excess weight loss postoperatively, were associated with a higher chance of MetS resolution.

Abstract
In the presence of stress, the hypothalamic-pituitary-adrenal (HPA) axis activity can be enhanced to promote the secretion of a large amount of glucocorticoids (GCs), which play an important role in the anabolism and catabolism of skeletal muscle. When the endogenous and exogenous glucocorticoids are deficient or excessive, the body will produce stress-related resistance and change the protein metabolism. In this study, we investigated the effect of GC receptor GRα on protein breakdown and synthesis in porcine skeletal muscle cells (PSCs). Overexpression of GRα was shown to increase the expression of protein degradation-related genes, while knockdown of GRα decreased the expression of these genes. Additionally, we found a relationship between GRα and solute carrier family 2 member 4 (SLC2A4), SLC2A4 expression level increases when stress occurs, suggesting that increasing SLC2A4 expression can partially alleviate stress-induced damage, and we found that there is a combination between them via luciferase reporter assays, which still needs to be confirmed in further studies.

Abstract
INTRODUCTION Polycystic ovary syndrome (PCOS) is the most common endocrine disorder of reproductive-aged women. Overweight and obesity commonly accompany the syndrome at the clinic and are significant concerns for women with PCOS. AREAS COVERED Herein, we provide an overview of the relevant literature on weight management strategies in women with PCOS. We performed an electronic-based search using PubMed until February 2021. We aimed to summarize available evidence of different weight-reducing interventions in PCOS and outline the gaps in our current knowledge and recommend areas for further research. EXPERT OPINION PCOS is closely linked to obesity and increased adiposity enhances severity and expression of PCOS phenotype. Current data suggest that weight loss is associated with improved metabolic, endocrine, reproductive, cardiovascular and psychological features in overweight and obese women with PCOS. Lifestyle interventions including diet and exercise, anti-obesity medications and bariatric surgery have been used as therapeutic approaches for short-term management of obesity in PCOS with varying success rates. Large and sufficiently powered studies are required in order to determine long-term effects of weight management strategies and potential benefits beyond weight loss in the syndrome. This would allow informing the guidelines to make PCOS specific evidence-based recommendations.

Abstract
Background: Rapid weight loss after bariatric surgery is a known risk factor for cholelithiasis development. This study aimed to estimate the incidence of cholelithiasis following bariatric surgery among morbidly obese patients who underwent bariatric surgery. Methods: This is a retrospective cohort study of all morbidly obese patients who underwent bariatric surgery in King Abdulaziz Medical City (Riyadh, Saudi Arabia) or King Abdulaziz Hospital (Al Ahsa, Saudi Arabia) between January 2015 and December 2018. Patients with a history of cholecystectomy or previous bariatric surgery were excluded. We estimated the incidence rate of cholelithiasis among the cohort. We also examined the associated risk factors of cholelithiasis development. Results: The study cohort contained 490 patients (38.7% males; 61.43% females) with a mean age of 36.87 ± 11.44 years. Most patients (58.54%) were followed up for 12 months. The incidence of cholelithiasis post-operation was 6.53% (n = 32). The average period of cholelithiasis formation was 12-24 months. The percentage of total weight loss (TWL%) was significantly associated with the development of cholelithiasis post-operatively. Conclusion: A significant association was found between weight loss following bariatric surgery and the incidence of cholelithiasis. Gender, age, and comorbidities were not associated with the formation of cholelithiasis. We recommend regular follow-up appointments with thorough patient education about gradual weight loss to reduce the risk of developing cholelithiasis.

Abstract
BACKGROUND Bariatric surgery has been widely used for the treatment of obesity and its related metabolic diseases, such as type 2 diabetes (T2D), hypertension, and sleep apnea syndrome. Polycystic ovary syndrome (PCOS) is a common reproductive endocrine metabolic disease; however, little attention has been paid to the efficacy of bariatric surgery on PCOS. OBJECTIVE To evaluate the efficacy of bariatric surgery on obese PCOS patients. SETTING A systematic review and meta-analysis at a university hospital. METHODS Online databases were searched for all studies reporting the efficacy of bariatric surgery for obese patients with PCOS up to October 2018. RESULTS A total of 9 studies with 234 obese PCOS patients were included in this article. The results of meta-analysis showed that after bariatric surgery, there was a significant reduction of the incidence of abnormal menstruation (relative risk [RR] .23; 95% confidence interval [CI] .13-.43; P < .00001) and hirsutism (RR .47; 95% CI .28-.79; P = .004). Bariatric surgery can also cause a decrease in the serum total testosterone level (mean difference [MD] = -25.82; 95% CI -30.06 to -21.58; P < .00001), serum free testosterone level (MD = -4.10; 95% CI -6.97 to -1.23; P = .005), and body mass index (MD = -14.51; 95% CI -17.88 to -11.14; P < .00001). It also showed a significant effect on T2D (RR .09; 95% CI .03-.32; P = .0002) and hypertension (RR .21; 95% CI .05-.98; P = .05) in obese patients with PCOS. CONCLUSIONS Bariatric surgery can reduce the incidence of abnormal menstruation, improve hyperandrogenism and its clinical manifestations, and decrease the body mass index, prevalence of T2D, and hypertension in obese patients with PCOS.

Abstract
Metabolic syndrome (MetS) is the constellation of metabolic risk factors that might foster development of type 2 diabetes and cardiovascular disease. Abdominal obesity and insulin resistance play a prominent role among all metabolic traits of MetS. Because intervention including weight loss can reduce these morbidity and mortality in MetS, early detection of the severity and complications of MetS could be useful. Recent advances in imaging modalities have provided significant insight into the development and progression of abdominal obesity and insulin resistance, as well as target organ injuries. The purpose of this review is to summarize advances in diagnostic imaging modalities in MetS that can be applied for evaluating each components and target organs. This may help in early detection, monitoring target organ injury, and in turn developing novel therapeutic target to alleviate and avert them.

Abstract
Background: Studies related to obesity have shown association with metabolic syndrome. Data showing that obesity is capable to cause low grade chronic inflammation, without its classic signs and symptoms, call attention to researches to study different cells types and the mechanism of the inflammatory process. Aim: To evaluate the variation of glycated hemoglobin (HbA1c) and the pro-inflammatory cytokine interleukin-6 (IL6) in diabetic patients with BMI <35 kg/m2 in the pre and postoperative of partial duodenal switch. Method: Nine patients were studied before and one year after the operation and the variation of the serum IL6 was measured by Elisa. The changes of HbA1c were also registered. Results: The pre-operative IL6 levels reached 65,50436±2,911993 pg/ml and one year after de operation 39,47739±3,410057 and the HbA1c average of 10,67 and 5.8 in the same period. Conclusion: The partial duodenal switch was efficient to control one year after the procedure the chronic inflammatory process caused by the diabetes mellitus type 2 with BMI <35 by dropping the IL6 levels and bringing the HbA1c to normal.

Abstract
Background: Roux-en-Y gastric bypass (RYGB) is considered the gold standard for gastric bypass, displaying better results for metabolic disorders than other surgical procedures over the long term. The aim of this study was to determine the effects of bariatric surgery, in particular the RYGB technique, on metabolic syndrome (MS) and other biochemical parameters implicit in the comorbid conditions associated with obesity, as well as to explore the influence of this surgical procedure on psychiatric comorbidity in the study population. Method: An observational retrospective cohort study based on 146 clinical records of patients having undergone RYGB between January 1, 2011, and January 1, 2014, was performed. Data related to metabolic and psychiatric comorbidity were gathered at three stages: prior to surgery and at 3 and 9 months following surgery. Results: There was a progressive and statistically significant reduction of all biochemical parameters analyzed at 3 and 9 months following surgery except high-density lipoprotein cholesterol, which significantly increased (beneficial) in value. These changes imply a remission of >90% for all metabolic disorders and the consequent tendency toward a reduction in prescribed pharmacological treatments, with MS found in only one subject at 9 months. There was, however, no significant reduction in pharmacological treatments for psychiatric comorbidities. Conclusion: Findings suggest that RYGB is an effective treatment for MS and other metabolic disorders but not for psychiatric comorbidities accompanying MS.

Abstract
Bariatric surgery is recognised as an effective treatment strategy for obese patients with type 2 diabetes mellitus. An increasing number of patients with type 1 diabetes mellitus also suffer with obesity and obesity-associated comorbidities but the role of bariatric and metabolic surgery in this group of patients is unclear. This systematic review investigates published English language scientific literature to understand the results of bariatric surgery in obese patients with type 1 diabetes mellitus. We found that these patients can experience significant weight loss and comorbidity resolution with bariatric surgery. Though most patients also see a decline in total insulin requirement, glycaemic control remains difficult. Most of the patients reported in literature have undergone gastric bypass but data is insufficient to recommend any particular procedure.
