Abstract
OBJECTIVE The impact of weight loss surgery on oral health is not clear. The aim of the present study was to investigate its impact on the risk for dental interventions. MATERIALS AND METHODS All adults who underwent metabolic surgery in Sweden between January 1, 2009 and December 31, 2018 were identified in the Scandinavian Obesity Surgery Registry (SOReg; n = 53,643). A control cohort from the general population was created, matched 10:1 on sex, age and place of residence (n = 536,430). All individuals were followed in the Swedish Dental Register regarding event rates for four types of dental intervention: restorative, endodontic and periodontal interventions, and tooth extractions. RESULTS The surgical cohort had increased interventional rates postoperatively regarding all studied outcomes except periodontal interventions. Dental interventions were more common in the surgical cohort both pre- and postoperatively. The difference between the groups increased markedly in the postoperative period. The between-group comparison postoperatively showed increased event rates for restorations (IRR 1.8; 95% CI 1.7-1.8), extractions (1.9; 95% CI 1.9-2.0) and endodontics (2.1; 95% CI 2.0-2.1). CONCLUSION The surgical intervention might cause a substantial negative impact on oral health. These results imply an important role for counselling metabolic surgery patients regarding preventive oral health measures.

Abstract
The prevalence of obesity has increased significantly over the last several decades, and with its increase comes a wide variety of comorbidities, such as diabetes and cardiovascular disease. Traditionally, diet and exercise have been prescribed for individuals to try and regain control of their weight and health status. Despite this successful method, the compliance rate is significantly below the desired amount. Over the last few decades, a new treatment has been offered to significantly decrease an individual's weight to an optimal BMI between 18 and 25 kg/m2. Bariatric surgery has been proposed to be the most appropriate treatment for obesity, and there are several different types of bariatric surgery: Roux-en-Y gastric bypass (RYGB), biliopancreatic diversion with duodenal switch (BPD-DS), adjustable gastric band (AGB), and sleeve gastrectomy (SG). Hormones may be significantly involved in losing and maintaining weight loss. This paper aims to evaluate hormone changes in appetite suppression, appetite activation, glycemic control, and lipid metabolism and how these impact overall weight loss concerning the most prominent surgeries. The hormones assessed were ghrelin, insulin, leptin, GLP-1, PYY, and adiponectin, and their levels before and after each surgery were compared. RYGB is one of the most successful types of bariatric surgeries, and this correlates with it having the most suppressed levels of ghrelin, insulin, and leptin following surgery with a slow return to normal. RYGB has also led to the most significant increased levels of PYY, pre- and post-prandial GLP-1, and adiponectin. Hormones following SG followed the hormone trend after RYGB but were not as prominent. BDP-DS has the highest success rate. However, numerous adverse effects have limited the amount of studies assessing the surgery. What was present was not as significant as RYGB, possibly due to manipulation.

Abstract
Diabetes mellitus is one of the major epidemics in the United States. It is heavily associated with obesity and multiple metabolic derangements that lead to long term morbidity, mortality as well as financial burden. Although medical therapy has been the mainstay in the management of diabetes mellitus, there remains a large portion of this patient population which struggles to obtain adequate glycemic control and long-term weight control with medical management alone. Bariatric surgery is a powerful tool in combating diabetes mellitus and affects glucose homeostasis through a variety of pathways. While it does provide a durable pathway for weight loss, improvement in glucose homeostasis is not only affected by the weight loss seen after bariatric surgery. Changes in gut hormone secretion, insulin regulation, and gut microbial composition also affect how these operations improve glucose homeostasis. Through improvement in the management of diabetes mellitus, comorbidities including cardiovascular disease, in turn demonstrate improvement. In this article, we will discuss the role of bariatric (metabolic) surgery as it relates to long term weight loss and the impact that weight loss has on improvement in diabetes mellitus.

ANZ J Surg 2022; 92:2896-2900. [PMID: 36128948 DOI: 10.1111/ans.17988] [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: 01/31/2022] [Revised: 07/30/2022] [Accepted: 08/04/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND In the laparoscopic Roux-en-Y gastric bypass procedure, the gastrojejunal stoma is constructed with either a circular (CSD) or a linear stapling device (LSD). The diameter of the stoma following stapling with the 21 mm CSD is expected to be approximately 12 mm (diameter of the anvil). Measuring the stoma diameter after linear stapling is a little more complex since the remaining opening in the linear anastomosis is closed by hand. The aim of this prospective randomized study was to follow up on changes in the diameter of gastrojejunal stomata after laparoscopic Roux-en-Y gastric bypass using either a CSD or an LSD between that at construction and at a long-term follow-up of 12-72 months later. METHODS Twenty patients were randomly assigned to gastrojejunostomy with either a 21 mm CSD or a 45 mm LSD. Directly after completion of the surgery, the diameter of the gastrojejunal stoma was measured using a Fogarty occlusion catheter and again at follow-up 12-72 months later. RESULTS Five patients were lost for follow-up, and 15 patients remained. The mean diameter of the CSD stomata at construction was 19.3 ± 5.3 mm (mean ± SD) and increased to 26.4 ± 6.6 mm at follow-up after a mean of 46 months (P = 0.02). The corresponding figures for the LSD stomata were 26.2 ± 4.1 mm, increasing to 32.7 ± 3.0 mm also after a mean follow-up of 46 months (P = 0.03). CONCLUSIONS The mean diameter of the circular stapled gastrojejunostomy stomata at construction was 20 mm, that is, considerably larger than the 12 mm expected. After a mean of 5 years, the mean diameter had increased by 37%. The mean diameter of the linear stapled stomata increased by 25%.

Abstract
INTRODUCTION Over the last two decades, a progressive increase in failure rate of bariatric surgery (BS) has occurred in conjunction with an exponential increase in BS worldwide. Bariatric surgeons are confronted with challenging situations in patients with a complex bariatric history. In this study, we aim to evaluate the feasibility and outcomes of revisional BS in patients with at least two or more previous bariatric procedures. METHODS Data were retrospectively retrieved from a prospectively held database of bariatric procedures performed at our tertiary referral bariatric center and included procedures done from February 2013 up to April 2019 by a single center. RESULTS Thirty patients underwent a third bariatric procedure. The median age was 40 (18-57) and 54 (27-69) years at the time of the first and the last procedures, respectively. Laparoscopic adjustable gastric banding was the first procedure in 26 patients. The complication rate was 33%; no patient required additional surgery because of postoperative complications. A total weight loss of 29.6% and an excess loss of 53.4% were obtained at a mean follow-up of 61 months after the last redo bariatric procedure. CONCLUSION This study indicates that redo BS either conversional or revisional is feasible and effective in patients with a complex bariatric history including two or more previous procedures. Careful patients' selection is mandatory and extensive information should be given on the increased risk of postoperative complications.

[PMID: 35949856 PMCID: PMC9254200 DOI: 10.12998/wjcc.v10.i18.6227] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2021] [Revised: 01/24/2022] [Accepted: 04/28/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) has been proposed as an effective and durable treatment for severe obesity and glucose metabolism disorders, and its prevalence has increased from 5% to 37% since 2008. One common complication after bariatric surgery is a postprandial hyperinsulinemic hypoglycemic state. While rare, insulinomas can cause this state, where symptoms are more common in the fasting state; thus, evaluation of insulin secretion is needed. Until now, there have been no reports of insulinoma after LSG.
CASE SUMMARY We describe the case of a 43-year-old woman who was referred to the obesity clinic 2 years after LSG was performed. She had symptoms of hypoglycemia predominantly in the fasting state and documented hypoglycemia of less than 30 mg/dL, which are compatible with Whipple’s triad. Initially, dumping syndrome was suspected, but after a second low fasting plasma glucose was documented, a 72-h fasting test was performed that tested positive. Computed tomography and endoscopic ultrasound were performed, identifying the presence of a homogeneous hypoechoic semioval tumoral lesion in the pancreas. The diagnosis was compatible with insulinoma. After laparoscopic enucleation of the insulinoma, the symptoms and hypoglycemia disappeared. The histopathological report described a well-differentiated grade 2 neuroendocrine tumor with positive chromogranin and synaptophysin and Ki67 immunopositivity in 4% of the neoplastic cells.
CONCLUSION Insulinoma after LSG is a rare condition, and clinicians must be aware of it, especially if the patient has hypoglycemic symptoms during the fasting state.

Abstract
PURPOSE Roux-en-Y gastric bypass (RYGB) surgery produces significant weight loss. However, a number of patients experience weight regain years after surgery. Factors driving weight regain after surgical interventions are currently being explored. Our objective was to investigate appetite-related measures associated with weight regain after RYGB surgery. MATERIALS AND METHODS Using a cross-sectional design, 29 participants (49.6 ± 9.1 years of age; current BMI 32.4 ± 4.7 kg/m2, 43.6 ± 8.9 months post-RYGB) were stratified into tertiles according to weight regain per month after nadir (weight maintenance (WM), n = 9; low weight regain (LWR), n = 10; and high weight regain (HWR), n = 10). The average weight regain was, by design, significantly different between the groups (WM = 2.2 ± 2.5 kg; LWR = 10.0 ± 3.4 kg; HWR = 14.9 ± 6.3 kg regained, p < 0.05). Appetite (visual analog scales), olfactory performance ("sniffin sticks"), eating behaviors (Three Factor Eating Questionnaire), food reward (Leeds Food Preference Questionnaire), and appetite-related hormones (ghrelin, PYY, GLP-1 and leptin) were measured fasting and in response to a standardized test meal. RESULTS Dietary restraint was significantly higher than clinical cutoffs in WM and LWR (p < 0.05). As expected, significant time effects were noted for ghrelin, PYY, and GLP-1, but there were no group differences. CONCLUSION The results suggest that appetite-related outcomes are similar across individuals who have maintained weight loss and experienced regain following RYGB.

Effect of sleeve gastrectomy, Roux-en-Y gastric bypass, and ileal transposition on myocardial ischaemia-reperfusion injury in non-obese non-diabetic rats. Sci Rep 2021; 11:23888.

Abstract
Bariatric surgery (BS) improves outcomes in patients with myocardial infarction (MI). Here we tested the hypothesis that BS-mediated reduction in fatal MI could be attributed to its infarct-limiting effect. Wistar rats were randomized into five groups: control (CON), sham (SHAM), Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), and ileotransposition (IT). Ten weeks later, animals were subjected to 30-min myocardial ischemia plus 120-min reperfusion. Infarct size (IS) and no-reflow area were determined histochemically. Fasting plasma levels of glucagon-like peptide-1 (GLP-1), leptin, ghrelin, and insulin were measured using ELISA. Compared with SHAM, RYGB and SG reduced IS by 22% (p = 0.011) and 10% (p = 0.027), and no-reflow by 38% (p = 0.01) and 32% (p = 0.004), respectively. IT failed to reduce IS and no-reflow. GLP-1 level was increased in the SG and RYGB groups compared with CON. In both the SG and RYGB, leptin level was decreased compared with CON and SHAM. In the SG group, ghrelin level was lower than that in the CON and SHAM. Insulin levels were not different between groups. In conclusion, RYGB and SG increased myocardial tolerance to ischemia-reperfusion injury of non-obese, non-diabetic rats, and their infarct-limiting effect is associated with decreased leptin and ghrelin levels and increased GLP-1 level.

Abstract
Obesity is a highly prevalent public health concern, attributed to multifactorial causes and limited in treatment options. Several comorbidities are closely associated with obesity such as the development of type 2 diabetes mellitus (T2DM), cardiovascular and cerebrovascular diseases, and nonalcoholic fatty liver disease (NAFLD). Bariatric surgery, which can be delivered in multiple forms, has been remarked as an effective treatment to decrease the prevalence of obesity and its associated comorbidities. The different types of bariatric surgery create a variety of new pathways for food to metabolize in the body and truncate the stomach's caliber. As a result, only a small quantity of food is tolerated, and the body mass index noticeably decreases. This review describes the improvements of obesity and its comorbidities following bariatric surgery and their mechanism of improvement. Additionally, endocrine function improvements after bariatric surgery, which contributes to the patients' health improvement, are described, including the role of glucagon-like peptide-1 (GLP-1), fibroblast growth factors 19 and 21 (FGF-19, FGF-21), and pancreatic peptide YY (PYY). Lastly, some of the complications of bariatric surgery, including osteoporosis, iron deficiency/anemia, and diarrhea, as well as their potential mechanisms, are described.

Abstract
AIMS Bariatric surgery (BS) is recommended for subjects with a Body Mass Index (BMI) over of 40 kg/m2 or with a BMI between 35 and 40 kg/m2 with obesity-related comorbidities. Aim of the study was to compare different types of BS with medical therapy (MT) for the treatment of obesity. DATA SYNTHESIS We conducted a network-meta-analysis (NMA) including randomized clinical trials comparing different BS techniques versus MT in people with obesity, with a duration ≥24 weeks (PROSPERO, #CRD42020160359). Primary endpoint was BMI. Indirect comparisons of different types of surgery were performed by NMA. Types of BS included: laparoscopic adjustable gastric banding (LAGB), Roux-en-Y gastric bypass, sleeve gastrectomy (SG), bilio-pancreatic diversion (BPD); greater curvature plication (GCP); one-anastomosis gastric bypass (OAGB); Laparoscopic Vertical Banded Gastroplasty (LVBG) and duodenal switch (DS). 43 trials were retrieved in this metanalysis. BS was associated with a significant reduction in BMI, systolic blood pressure, triglyceride and fasting glucose, and with a significant increase of HDL cholesterol when compared to MT. In direct comparisons, RYGB was more effective than LAGB, LVBG, and GCP, but less effective than DS, whereas LAGB was less effective than LVBG and SG. In the NMA, DS and BPD appeared to be more effective than other procedures. CONCLUSIONS BS produces a greater weight loss than MT in morbidly obese patients, inducing a greater improvement of obesity-associated metabolic parameters. Available data are insufficient to assess the effect of BS on mortality. Different surgical procedures are heterogeneous for efficacy and safety.

Abstract
BACKGROUND Metabolic/bariatric surgery is a highly effective treatment for obesity and metabolic diseases. Serum glucagon, bile acids, and FGF-19 are key effectors of various metabolic processes and may play central roles in bariatric surgical outcomes. It is unclear whether these factors behave similarly after Roux-en-Y gastric bypass (RYGB) vs vertical sleeve gastrectomy (VSG). METHODS Serum glucagon, bile acids (cholic acid [CA], chenodeoxycholic acid [CDCA], deoxycholic acid [DCA]), and FGF-19 were analyzed in samples of fasting blood collected before bariatric surgery, on postoperative days 2 and 10, and at 3- and 6-month follow-up. RESULTS From September 2016 to July 2017, patients with obesity underwent RYGB or VSG; 42 patients (RYGB n = 21; VSG n = 21) were included in the analysis. In the RYGB group, glucagon, CA, and CDCA increased continuously after surgery (p = 0.0003, p = 0.0009, p = 0.0001, respectively); after an initial decrease (p = 0.04), DCA increased significantly (p = 0.0386). Serum FGF-19 was unchanged. In the VSG group, glucagon increased on day 2 (p = 0.0080), but decreased over the 6-month study course (p = 0.0025). Primary BAs (CA and CDCA) decreased immediately after surgery (p = 0.0016, p = 0.0091) and then rose (p = 0.0350, p = 0.0350); DCA followed the curve of the primary BAs until it fell off at 6 months (p = 0.0005). VSG group serum FGF-19 trended upward. CONCLUSION RYGB and VSG involve different surgical techniques and final anatomical configurations. Between postoperative day 2 and 6-month follow-up, RYGB and VSG resulted in divergent patterns of change in serum glucagon, bile acids, and FGF-19.

Obes Surg 2021; 31:4005-4014. [PMID: 34240316 DOI: 10.1007/s11695-021-05534-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Revised: 06/14/2021] [Accepted: 06/17/2021] [Indexed: 02/06/2023]
Abstract
PURPOSE This study aims to examine the changes of glucose metabolism, glucose variability (GV), and ghrelin secretion within 1 week following SG in Chinese patients with obesity. MATERIALS AND METHODS Forty-nine patients with obesity (15 with type 2 diabetes) were enrolled to undergo SG. Within 1 week before and after surgery, liquid meal tests were performed in all subjects, and continuous glucose monitoring (CGM) was performed in diabetic patients. Blood samples were collected at 0, 15, 30, 45, 60, 120, and 180 min for glucose, C-peptide, insulin, and ghrelin analysis in liquid meal test. Mean amplitude of glucose excursions (MAGE), standard deviations (SD), and percent time-in-range (%TIR) determined by CGM were analyzed. RESULTS Both in diabetic and non-diabetic groups, significant decrease was observed in glucose, insulin, C-peptide, and ghrelin. Homeostasis model assessment-insulin resistance and liver fat content was decreased. In diabetic group, MAGE and SD were decreased significantly, and the percent time-in-range was higher. The decrease in blood glucose was positively correlated with the decrease in ghrelin concentration in non-diabetic group. CONCLUSION Within 1 week after SG, both glucose metabolism and glucose variability were improved significantly. Suppression of ghrelin secretion postoperatively might be a driver of this early improved glycemia homeostasis.

Abstract
Obesity and its related complications comprise a serious public health problem worldwide, and obesity is increasing in China. Metabolic surgery is a new type of treatment with unique advantages in weight loss and obesity-related metabolic complications. The pathogenesis of obesity is complex and not yet fully understood. Here, we review the current efficacy and safety of metabolic surgery, as well as recent progress in mechanistic studies and surgical procedures in China. The exciting and rapid advances in this field provide new opportunities for patients with obesity and strike a balance between long-term effectiveness and safety.

Abstract
IMPORTANCE Obesity is associated with a number of noncommunicable chronic diseases and is purported to cause premature death. OBJECTIVE To summarize evidence on the temporality of the association between higher body mass index (BMI) and 2 potential mediators: chronic inflammation and hyperinsulinemia. DATA SOURCES MEDLINE (1946 to August 20, 2019) and Embase (from 1974 to August 19, 2019) were searched, although only studies published in 2018 were included because of a high volume of results. The data analysis was conducted between January 2020 and October 2020. STUDY SELECTION AND MEASURES Longitudinal studies and randomized clinical trials that measured fasting insulin level and/or an inflammation marker and BMI with at least 3 commensurate time points were selected. DATA EXTRACTION AND SYNTHESIS Slopes of these markers were calculated between time points and standardized. Standardized slopes were meta-regressed in later periods (period 2) with standardized slopes in earlier periods (period 1). Evidence-based items potentially indicating risk of bias were assessed. RESULTS Of 1865 records, 60 eligible studies with 112 cohorts of 5603 participants were identified. Most standardized slopes were negative, meaning that participants in most studies experienced decreases in BMI, fasting insulin level, and C-reactive protein level. The association between period 1 fasting insulin level and period 2 BMI was positive and significant (β = 0.26; 95% CI, 0.13-0.38; I2 = 79%): for every unit of SD change in period 1 insulin level, there was an ensuing associated change in 0.26 units of SD in period 2 BMI. The association of period 1 fasting insulin level with period 2 BMI remained significant when period 1 C-reactive protein level was added to the model (β = 0.57; 95% CI, 0.27-0.86). In this bivariable model, period 1 C-reactive protein level was not significantly associated with period 2 BMI (β = -0.07; 95% CI, -0.42 to 0.29; I2 = 81%). CONCLUSIONS AND RELEVANCE In this meta-analysis, the finding of temporal sequencing (in which changes in fasting insulin level precede changes in weight) is not consistent with the assertion that obesity causes noncommunicable chronic diseases and premature death by increasing levels of fasting insulin.

Abstract
Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) reduce blood pressure (BP) in obese patients with hypertension (HTN). We compared the effect of RYGB and SG on BP in obese patients with HTN at a large-volume, private bariatric surgery center using a propensity score analysis. The measurement and management of BP were exclusively left to the patient's provider without any involvement of Tulane investigators. At month 1, RYGB and SG equally decreased: (1) mean body weight: 12.7 vs 13.2 kg (p=not significant (NS)) (2) systolic/diastolic BP: 8.5/5.3 vs 8.0/4.2 mm Hg (p=NS) and (3) average number of antihypertensive medications from 1.5 to 0.8 and from 1.6 to 0.6 per patient (p=NS). From month 1 to 12, BP remained unchanged after RYGB but tended to increase from month 6 to 12 after SG. Remission of HTN occurred in 52% and 44% of patients after RYGB and SG. In contrast to the full effect of RYGB and SG on BP at 1 month, body weight decreases steadily over 12 months after RYGB and SG. In conclusion, early after surgery, RYGB and SG equally reduce BP in obese patients with HTN. Thereafter, RYGB has a more sustained effect on BP than SG.

Abstract
Metabolic syndrome (MS) is defined as the constellation of obesity, insulin resistance, high serum triglycerides, low high-density lipoprotein cholesterol, and high blood pressure. It increasingly affects more and more people and progressively evolves into a serious issue with widespread healthcare, cost, and quality of life associated consequences. MS is associated with increased morbidity and mortality due to cardiovascular or chronic liver disease. Conservative treatment, which includes diet, exercise, and antidiabetic agents, is the mainstay of treatment, but depends on patient compliance to medical treatment and adherence to lifestyle modification recommendations. Bariatric surgery has recently emerged as an appropriate alternative treatment with promising long-term results. Sleeve gastrectomy and Roux-en-Y gastric bypass constitute the most commonly performed procedures and have been proven both cost-effective and safe with low complication rates. Liver transplantation is the only definitive treatment for end-stage liver disease and its utilization in patients with non-alcoholic steatohepatitis has increased more than fivefold over the past 15 years. In this review, we summarize current state of evidence on the surgical treatment of MS.

Abstract
OBJECTIVE To perform a structured systematic review and meta-analysis to evaluate changes in ghrelin, glucagon-like peptide-1 (GLP-1), peptide YY (PYY), and gastric inhibitory peptide (GIP) gut hormone levels in patients after sleeve gastrectomy. BACKGROUND Despite sleeve gastrectomy becoming the most common surgical weight loss procedure, weight loss mechanisms remain less clear. METHODS Searches of PubMed, EMBASE, Web of Science, and Cochrane Library databases were performed through April 1, 2019, in accordance with PRISMA and MOOSE guidelines. Randomized controlled trials and prospective observational studies evaluating pre and post-procedure hormones fasting ghrelin, postprandial GLP-1, postprandial PYY, and fasting GIP levels were included. Hedge g with random-effects models were used to determine pooled effect size and corresponding 95% confidence intervals (CIs). RESULTS A total of 28 studies (n = 653; 29.56% male) were included. Mean age was 42.00 ± 5.48 years, with average follow-up of 11.70 ± 11.38 months. Pre-procedure body mass index (BMI) was 46.01 ± 4.07 kg/m with a postsleeve gastrectomy BMI of 34.07 ± 3.73 kg/m, representing total body weight loss of 25.13 ± 4.44% and excess weight loss of 57.48 ± 9.64% (P < 0.001). Ghrelin decreased (Hedge g -1.486, 95% CI -1.884 to -1.089, I = 91.95%), whereas GLP-1 and PYY increased post-procedure (Hedge g 1.095, 95% CI 0.509 to 1.642, I = 84.38%; and Hedge g 1.396, 95% CI 0.781 to 2.011, I = 84.02%, respectively). GIP did not significantly change (Hedge g -0.213, 95% CI -1.019 to 0.592, I = 79.65%). CONCLUSIONS Fasting ghrelin levels decreased, whereas postprandial GLP-1 and PYY increased after sleeve gastrectomy. Fasting GIP levels remained unchanged. Future studies are needed to assess the role of these gut hormones and relationship to weight loss and metabolic outcomes.

Abstract
Background Ghrelin and obestatin are two gastric hormones encoded by the same preproghrelin gene that convey information concerning nutritional status to the central nervous system. Ghrelin has been considered as an appetite stimulating peptide that has a role in the regulation of energy homeostasis. Obestatin has been described for its appetite suppressing effects opposing ghrelin's effect on food intake. The study aimed to evaluate ghrelin, obestatin and the ghrelin/obestatin ratio in obese children compared to non-obese and correlate them to food macronutrients intake. Methods This study is a cross-sectional case control study comprising 60 obese children, in addition to 31 age- and sex-matched controls. All children were subjected to clinical examination, anthropometric assessment, and a 3-day 24-h dietary recall. Fasting serum ghrelin and obestatin levels were evaluated, the ghrelin/obestatin ratio was calculated and they were correlated to macronutrients intake. Results Obese children had significantly lower serum fasting levels of ghrelin, obestatin and the ghrelin/obestatin ratio than the control group. The mean intake of total energy and macronutrients was significantly higher in obese children. Ghrelin showed positive correlation with total energy and fat intake in the obese group. Obestatin had positive correlations with total energy and fat intake while the ghrelin/obestatin ratio had a negative correlation with the total energy intake in the control group. Conclusions Ghrelin, obestatin and the ghrelin/obestatin ratio were significantly lower in obese children and significantly associated with their total energy intake. Disturbed ghrelin to obestatin balance may have a role in the etiology and pathophysiology of obesity.

Abstract
BACKGROUND Sleeve gastrectomy (SG) is one of the most effective treatments for severe obesity, but weight regain after surgery is a challenging issue. The mechanism of postoperative weight relapse is barely understood because of the lack of long-term data. OBJECTIVES To review and synthesize current evidence related to factors that contribute to weight regain after SG. METHODS Whittemore and Knafl's integrative method guided the research. The databases PubMed, EMBASE, and CINAHL, as well as 2 selected journals, were searched through October 2018 to gather English-language journal articles on the potential predictors of post-SG weight regain among adult populations. Only articles with sample size ≥10 were included. A narrative synthesis was used to analyze the 17 studies included in the review. RESULTS In recent years there has been an upward trend in the published reports of SG on longer-term outcomes. After a review of 6863 records, 17 eligible studies were identified, reporting various definitions of weight regain and 3 main categories of predictors: surgical/anatomic factors, hormonal/metabolic imbalance, and behavioral/mood factors. The 17 studies used quantitative (n = 16) and qualitative methods (n = 1). CONCLUSION There is a dearth of available literature addressing predictors of weight regain after SG, and the inconsistency in the definition of regain limited the comparability between studies. Besides the surgical/anatomic factors that have been reported as significant predictors, other modifiable factors such as behavioral and psychosocial determinants need to be further investigated.
