Pre-Surgery Cortisol Levels as Biomarker of Evolution after Bariatric Surgery: Weight Loss and Weight Regain. J Clin Med 2024; 13:5146. [PMID: 39274358 PMCID: PMC11396150 DOI: 10.3390/jcm13175146] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2024] [Revised: 08/09/2024] [Accepted: 08/10/2024] [Indexed: 09/16/2024] Open
Abstract
Background: Bariatric surgery (BS) is effective for achieving significant weight loss. However, weight regain (WR) is an emerging problem. Objective: To assess the prognostic value of morning serum cortisol, a 1 mg dexamethasone suppression test (DST), 24 h urinary free cortisol (UFC) and late-night salivary cortisol (LNSC) in a cohort of patients with severe obesity (pwSO) undergoing BS in terms of weight loss and WR. Methods: Patients scheduled for BS underwent the following procedures at baseline, 12 months and 24 months after BS: medical history, anthropometric data, blood analysis and cortisol tests. We evaluated total weight loss (TWL) ≥ 30% at 1 year and WR after 2 years as an increase of ≥10% of the maximum weight lost. Results: In total, 142 subjects were included; 101 (71.1%) were females and the mean age was 45.9 ± 9.2 years. Up to 76.8% of subjects achieved ≥30% TWL, without statistically significant differences in DST results or morning serum cortisol, UFC or LNSC levels. However, a higher pre-surgery morning serum cortisol level was a significant predictor of a WR ≥ 10% (cortisol 17.8 [IQR 13.1-18.5] vs. 12.0 [IQR 8.8-15.8] μg/dL; p < 0.01); OR of 1.216 (95% CI 1.069-1.384); AUC [0.761, CI: (0.616-0.906); p < 0.01]. A cut-off value of cortisol > 13.0 μg/dL was predictive of a WR ≥ 10% (sensitivity 0.71; specificity 0.63). Conclusions: No cortisol test was useful in predicting weight loss; however, the pre-surgery morning serum cortisol level was able to predict a WR ≥ 10% in a cohort of pwSO 2 years after BS. A cut-off value of cortisol > 13 μg/dL might be an easy tool to identify patients at higher risk of WR, enabling healthcare providers to implement tailored, long-term strategies to minimize this outcome.

Associations of change in body fat percentage with baseline body composition and diabetes remission after bariatric surgery. Obesity (Silver Spring) 2024; 32:871-887. [PMID: 38515375 DOI: 10.1002/oby.24003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/02/2023] [Revised: 12/08/2023] [Accepted: 01/11/2024] [Indexed: 03/23/2024]
Abstract
OBJECTIVE The objective of this study was to determine the role of body fat percentage (BFP) changes in diabetes remission (DR) and the association between baseline body composition and its changes after bariatric surgery. METHODS We analyzed 203 patients with type 2 diabetes who underwent Roux-en-Y gastric bypass. Body composition was measured using a gold-standard-derived predictive equation and magnetic resonance imaging. Body composition changes were calculated as 100 × (baseline value - follow-up value)/baseline value. We verified the results in a laparoscopic sleeve gastrectomy cohort with 311 patients. RESULTS Compared with non-remission patients in the Roux-en-Y gastric bypass cohort, those who achieved DR showed a higher baseline fat-free mass index (FFMI) and experienced the most significant changes in BFP (p < 0.001). In comparative analyses, BFP changes were significantly better than BMI changes in identifying short- and long-term DR. Linear regression analysis identified FFMI as the most significant baseline variable correlated with BFP changes (p < 0.001). Baseline BMI was positively correlated with changes in BFP but negatively correlated with changes in FFMI. These findings were replicated in the laparoscopic sleeve gastrectomy cohort. CONCLUSIONS BFP changes determine DR after bariatric surgery, and baseline FFMI is crucial for BFP changes. A low initial BMI is associated with a smaller BFP reduction and greater FFMI loss after bariatric surgery.

The Effects of Post-Surgical Pregnancy on Weight Loss Trajectories after Bariatric Surgery: Are Initial Weight and Age Prognostic Factors? J Clin Med 2024; 13:1264. [PMID: 38592078 PMCID: PMC10931694 DOI: 10.3390/jcm13051264] [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: 12/14/2023] [Revised: 02/13/2024] [Accepted: 02/19/2024] [Indexed: 04/10/2024] Open
Abstract
Introduction: A substantial percentage of patients undergoing bariatric surgery are of childbearing age. Pregnancy outcomes after bariatric surgery are known. However, there are limited data on the impact of pregnancy on weight loss after surgery. Objectives: This study aims to evaluate the effects of pregnancy on post-bariatric surgery weight loss trajectories (WLTs) and to determine the association with age and initial weight. Methods: All who had primary bariatric surgeries (Roux-en-Y gastric bypass or sleeve) between September 2015 and July 2020 were classified into two groups: post-surgery gravid (GG) and post-surgery non-gravid (NG). WLTs were examined using a random intercept mixed-effects model with repeated measures nested within patients. The post-surgery/pre-gravid time phase (PoPG) was modelled using a third-degree polynomial. For GG, two third-degree spline functions modelled the post-surgery while gravid (PoWG) and post-partum (PoPP) time phases. Age and initial weight were used to control for pre-existing differences during PoPG. Weight differences at 6 months PoPP were examined by applying general linear hypothesis testing to the mixed-model results. Results: A total of 508 patients were included, 20 in GG and 488 in NG. The mean age at surgery was 33 years in GG and 37 years in NG. The mean initial BMI was 47 kg/m2 and 43 kg/m2, respectively. During PoPG, adjusted average weight in both groups follows the path across time. For GG, weight decreases and then increases during PoWG. For GG during PoPP, weight immediately decreases after delivery and then increases over time to levels similar to NG. Weight differences at 6 months PoPP for GG and NG were not statistically different. Older age was associated with reduced weight loss during PoPG by Baseline Age, while higher initial weight was associated with increased weight loss during PoPG by Baseline Weight. In both instances, these effects attenuate over time. Conclusions: This model indicates that pregnancy following bariatric surgery affects WLT during PoWG and PoPP, and no difference in weight is expected after 6 months post-gravid. Age and initial weight could be considered prognostic factors during PoPG. Patients wishing to conceive should undergo preconception counselling and be advised to avoid pregnancy during the period of rapid weight loss. They also should be informed that WLT may vary during pregnancy and early post-partum.

Weight management treatment modalities in patients with overweight or obesity: A retrospective cohort study of administrative claims data. OBESITY PILLARS 2023; 7:100072. [PMID: 37990675 PMCID: PMC10661997 DOI: 10.1016/j.obpill.2023.100072] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Revised: 05/22/2023] [Accepted: 05/22/2023] [Indexed: 11/23/2023]
Abstract
Background The purpose of this study was to describe demographic and clinical characteristics among patients who have medical encounters for weight management treatments and to investigate the association of those characteristics with treatment modality. Methods This was a retrospective database study using medical claims, pharmacy claims, and enrollment information from commercial and Medicare Advantage with Part D members in the Optum Research Database from 01/01/2011-2/29/2020. Adult patients with a claim for a weight management treatment from 01/01/2012-2/28/2019 were categorized into cohorts according to the highest intensity intervention received. To examine the association between patient characteristics and treatment modality received, a multinomial logit model was performed. Results Cohorts by increasing intensity included lifestyle intervention (LSI, n = 67,679), weight reduction pharmacotherapy (WRRx) with an anti-obesity medication (AOM, n = 6,905), weight reduction procedure (WRP, n = 1,172), and weight reduction surgery (WRS, n = 18,036). Approximately 32.1% and 16.6% of patients who received WRS or WRP had an LSI during the 12-month baseline, and only 0.6% and 0.4% had treatment with long-term AOMs. In a multinomial logit model, patients with type 2 diabetes (not including WRRx cohort), respiratory disorders, cardiovascular risk factors, pain disorders, and mental health conditions had increased odds of treatment with higher intensity intervention versus LSI. Patients who were male, received an intervention more recently (2016-2019), or had a Charlson comorbidity score of 1 (compared to 0) had decreased odds of treatment with higher intensity interventions. Conclusion In this study, age, sex, body mass index, obesity-related complications, and Charlson comorbidity score appeared to influence the type of weight management treatment modality received. This study improves understanding of weight management treatment utilization and identifies gaps and opportunities to improve obesity care with the appropriate use of different treatment modalities.

Abstract
PURPOSE Bariatric surgery is the most effective treatment for severe obesity in adults and has shown promising results in young adults. Lack of insight regarding efficacy and safety outcomes might result in delayed bariatric surgery utilization in young adults. Therefore, this study aimed to assess the efficacy and safety of bariatric surgery in young adults compared to adults. METHODS This is a nationwide population-based cohort study utilizing data from the Dutch Audit Treatment of Obesity (DATO). Young adults (aged 18-25 years) and adults (aged 35-55 years) who underwent primary Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) were included. Primary outcome was percentage total weight loss (%TWL) until five years postoperatively. RESULTS A total of 2,822 (10.3%) young adults and 24,497 (89.7%) adults were included. The follow-up rates of the young adults were lower up to five years postoperatively (46.2% versus 56.7% three years postoperatively; p < 0.001). Young adults who underwent RYGB showed superior %TWL compared to adults until four years postoperatively (33.0 ± 9.4 versus 31.2 ± 8.7 three years after surgery; p < 0.001). Young adults who underwent SG showed superior %TWL until five years postoperatively (29.9 ± 10.9 versus 26.2 ± 9.7 three years after surgery; p < 0.001). Postoperative complications ≤ 30 days were more prevalent among adults, 5.3% versus 3.5% (p < 0.001). No differences were found in the long term complications. Young adults revealed more improvement of hypertension (93.6% versus 78.9%), dyslipidemia (84.7% versus 69.2%) and musculoskeletal pain (84.6% versus 72.3%). CONCLUSION Bariatric surgery appears to be at least as safe and effective in young adults as in adults. Based on these findings the reluctance towards bariatric surgery in the younger age group seems unfounded.

A Multi-center Study and Narrative Review. Obes Surg 2023; 33:1431-1448. [PMID: 36905504 PMCID: PMC10156787 DOI: 10.1007/s11695-023-06532-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2022] [Revised: 02/24/2023] [Accepted: 02/24/2023] [Indexed: 03/12/2023]
Abstract
INTRODUCTIONS Revision surgery because of weight recurrence is performed in 2.5-33% of primary vertical banded gastroplasty (VBG), laparoscopic sleeve gastrectomy (LSG), and gastric band (GB) cases. These cases qualify for revisional Roux-en-Y gastric bypass (RRYGB). METHODS This retrospective cohort study analyzed data from 2008 to 2019. A stratification analysis and multivariate logistic regression for prediction modeling compared the possibility of sufficient % excess weight loss (%EWL) ≥ 50 or insufficient %EWL < 50 between three different RRYGB procedures, with primary Roux-en-Y gastric bypass (PRYGB) as the control during 2 years of follow-up. A narrative review was conducted to test the presence of prediction models in the literature and their internal and external validity. RESULTS A total of 558 patients underwent PRYGB, and 338 underwent RRYGB after VBG, LSG, and GB, and completed 2 years of follow-up. Overall, 32.2% of patients after RRYGB had a sufficient %EWL ≥ 50 after 2 years, compared to 71.3% after PRYGB (p ≤ 0.001). The total %EWL after the revision surgeries for VBG, LSG, and GB was 68.5%, 74.2%, and 64.1%, respectively (p ≤ 0.001). After correcting for confounding factors, the baseline odds ratio (OR) or sufficient %EWL ≥ 50 after PRYGB, LSG, VBG, and GB was 2.4, 1.45, 0.29, and 0.32, respectively (p ≤ 0.001). Age was the only significant variable in the prediction model (p = 0.0016). It was impossible to develop a validated model after revision surgery because of the differences between stratification and the prediction model. The narrative review showed only 10.2% presence of validation in the prediction models, and 52.5% had external validation. CONCLUSION Overall, 32.2% of all patients after revisional surgery had a sufficient %EWL ≥ 50 after 2 years, compared to PRYGB. LSG had the best outcome in the revisional surgery group in the sufficient %EWL group and the best outcome in the insufficient %EWL group. The skewness between the prediction model and stratification resulted in a partially non-functional prediction model.

Abstract
The outcomes of bariatric surgery, while often impressive, are not universally satisfactory; they vary from patient to patient and from operation to operation. Between 20-30% of patients experience suboptimal weight loss or substantial weight regain early in their postoperative course. Confronted with this chronic disease, and given that failures are difficult to manage, it is essential to better characterize obesity preoperatively, considering other metrics beyond just the body mass index (BMI), to select the best candidates for surgery and optimize the benefit/risk ratio. Based on the data of the most recent studies on bariatric surgery, our objective is to identify the predictive factors of weight loss as well as the risk factors of failure. Our analysis indicates that the choice of the surgical technique, age, initial BMI, ethnic origin, the presence of eating disorders and metabolic factors all have an impact on weight-loss outcomes after bariatric surgery. Thus, it is of major importance to carefully select patients during a preoperative multidisciplinary discussion in order to optimize weight loss and metabolic outcomes.

Abstract
The fastest-growing age group undergoing cosmetic procedures are those over age 60, i.e. the aging patient group. While advanced age is a known predictor for increased surgical complications, the effects of age on complications in specific plastic procedures have yet to be thoroughly investigated. To determine the relationship between increased age and risk of surgical complications following body contouring procedures, specifically: abdominoplasty, brachioplasty, mastopexy, bilateral reduction, and thigh lift. A retrospective analysis of all patients undergoing body contouring procedures of the categories mentioned above between 2000-2018 at a tertiary university medical center. Patients were divided into two age groups: those below and those above, age 60. Data analysis included: demographics, underlying medical conditions, procedure type, and occurrence of postoperative complications (according to the Clavien-Dindo classification system). 803 body contouring procedures were identified, with 12% performed on the aging population. Aging patients had more underlying medical conditions than the younger ones. While the distribution of procedure type was similar in both groups, mastopexy was more common in aging patients. Of the 107 procedures identified as having complications, 37 were classified as grade I, 38 as grade II, and 32 as grade III. As a categorical variable, no relationship was found between the age of the patients and an increased risk of postoperative complications (age cut-off as 60). However, as a continuous variable, increased age did increase the overall risk of postoperative complications, although no optimal age as a cut-off point was identified. In multivariant analysis, diabetes mellitus with abdominoplasty was identified as a risk factor for postoperative complications. Conclusions: When undergoing body contouring procedures, we found that patients over the age of 60 are not at increased risk for postoperative complications than those under that age. Although age as a continuous variable was found to increase the overall postoperative complications, no optimal age could be defined as a cut-off point.

Adherence of Obese Patients from Poland and Germany and Its Impact on the Effectiveness of Morbid Obesity Treatment. Nutrients 2022; 14:nu14183880. [PMID: 36145256 PMCID: PMC9505872 DOI: 10.3390/nu14183880] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2022] [Revised: 09/13/2022] [Accepted: 09/15/2022] [Indexed: 11/17/2022] Open
Abstract
This study aimed to investigate and compare the adherence of patients treated for morbid obesity living in Poland and Germany. Methods: A cross-sectional international multicenter survey design was adopted. The study involved 564 adult subjects treated for morbid obesity at selected healthcare facilities in Germany (210 participants) and Poland (354 participants). A validated, custom-made questionnaire based on the literature related to this issue was used. Results: The degree of adherence was higher, but not statistically significant, among Polish patients (83.82% vs. 78.33%, p = 0.26140). Patient adherence was associated with gender, age, level of education, duration of obesity, number of health professionals involved in obesity treatment, and type of obesity treatment (p < 0.05). A positive correlation was observed in the case of age, level of education, and a growing number of health professionals involved in obesity treatment, whereas a negative correlation was observed in the case of the duration of obesity. Patients who underwent bariatric surgery significantly more often followed medical recommendations regarding lifestyle changes, compared to obese participants treated only conservatively. Adherence in the field of obesity treatment significantly increases the percentage of total weight loss and excess weight loss due to applied obesity treatment among both Polish and German groups (p < 0.001). Both the percentage of total weight loss and that of excess weight loss were significantly higher in the group of adherent patients compared to the nonadherent patients (p < 0.00001). The levels of perceived anxiety, stress, and depression were significantly higher in nonadherent patients in both countries. Conclusions: These findings confirm the role of adherence in the effective and satisfactory treatment of morbid obesity. There is a great need to improve patient adherence to overcome the consequences of the obesity pandemic.

Abstract
Bariatric surgery (BS) is the most effective treatment strategy for obesity. Nevertheless, a subset of patients does not reach a successful weight loss or experience long-term weight regain. Conflicting evidence exists regarding predictors of BS outcomes. We aimed to define the early factors linked to 3 year unsuccessful weight loss in order to promote a tailored close follow-up. We enrolled 443 patients who underwent BS from January 2014 to December 2018 with a 3 year follow-up. An unsuccessful BS outcome was defined as a percentage of total weight loss (%TWL) < 20. We compared the characteristics between successful and unsuccessful patients in order to identify predictor factors of unsuccess after surgery. We found that the proportion of patients with unsuccessful weight loss progressively increased from one to three years after BS. In a multiple regression model, only 1 month %TWL and sleeve gastrectomy (SG) were significantly associated with 3 year unsuccessful weight loss. We stratified our cohort in four groups according to the risk of BS unsuccess, in terms of 1 month %TWL and type of surgery (SG vs gastric bypass). Interestingly, groups showed a significant difference in terms of %TWL at each follow-up point. Patients submitted to SG with lower 1 month %TWL must be considered at higher risk of future weight regain; consequently, they require a tailored and closer follow-up.

Sex-specific differences in metabolic outcomes after sleeve gastrectomy and intermittent fasting in obese middle-aged mice. Am J Physiol Endocrinol Metab 2022; 323:E107-E121.

Abstract
Despite the high prevalence of obesity among middle-aged subjects, it is unclear if sex differences in middle age affect the metabolic outcomes of obesity therapies. Accordingly, in this study, middle-aged obese female and male mice were randomized to one of three groups: sleeve gastrectomy (SG), sham surgery ad libitum (SH-AL), or sham surgery with weight matching to SG through intermittent fasting with calorie restriction (SH-IF). Comprehensive measures of energy and glucose homeostasis, including energy intake, body weight, energy expenditure, glucose and insulin tolerance, and interscapular brown adipose tissue (iBAT) sympathetic innervation density were obtained. At the end of 8 wk, SG and SH-IF females had better metabolic outcomes than their male counterparts. SG females had improved weight loss maintenance, preservation of fat-free mass (FFM), higher total energy expenditure (TEE), normal locomotor activity, and reduced plasma insulin and white adipose tissue (WAT) inflammatory markers. SH-IF females also had lower plasma insulin and WAT inflammatory markers, and higher TEE than SH-IF males, despite their lower FFM. In addition, SH-IF females had higher iBAT sympathetic nerve density than SG and SH-AL females, whereas there were no differences among males. Notably, SH-IF mice of both sexes had the most improved glucose tolerance, highlighting the benefits of fasting, irrespective of weight loss. Results from this study demonstrate that in middle-aged obese mice, female sex is associated with better metabolic outcomes after SG or IF with calorie restriction. Clinical studies are needed to determine if sex differences should guide the choice of obesity therapies.NEW & NOTEWORTHY SG or IF with calorie restriction produces better metabolic outcomes in females than in males. IF with calorie restriction prevents metabolic adaptation, even in the face of fat-free mass loss. IF with calorie restriction in females only, is associated with increased iBAT sympathetic innervation, which possibly mitigates reductions in energy expenditure secondary to fat-free mass loss. Lastly, IF leads to better glucose homeostasis than SG, irrespective of sex.

Front Endocrinol (Lausanne) 2022; 13:921353.

Abstract
Obesity is a global health challenge that warrants effective treatments to avoid its multiple comorbidities. Bariatric surgery, a cornerstone treatment to control bodyweight excess and relieve the health-related burdens of obesity, can promote accelerated bone loss and affect skeletal strength, particularly after malabsorptive and mixed surgical procedures, and probably after restrictive surgeries. The increase in bone resorption markers occurs early and persist for up to 12 months or longer after bariatric surgery, while bone formation markers increase but to a lesser extent, suggesting a potential uncoupling process between resorption and formation. The skeletal response to bariatric surgery, as investigated by dual-energy X-ray absorptiometry (DXA), has shown significant loss in bone mineral density (BMD) at the hip with less consistent results for the lumbar spine. Supporting DXA studies, analyses by high-resolution peripheral quantitative computed tomography (HR-pQCT) showed lower cortical density and thickness, higher cortical porosity, and lower trabecular density and number for up to 5 years after bariatric surgery. These alterations translate into an increased risk of fall injury, which contributes to increase the fracture risk in patients who have been subjected to bariatric surgery procedures. As bone deterioration continues for years following bariatric surgery, the fracture risk does not seem to be dependent on acute weight loss but, rather, is a chronic condition with an increasing impact over time. Among the post-bariatric surgery mechanisms that have been claimed to act globally on bone health, there is evidence that micro- and macro-nutrient malabsorptive factors, mechanical unloading and changes in molecules partaking in the crosstalk between adipose tissue, bone and muscle may play a determining role. Given these circumstances, it is conceivable that bone health should be adequately investigated in candidates to bariatric surgery through bone-specific work-up and dedicated postsurgical follow-up. Specific protocols of nutrients supplementation, motor activity, structured rehabilitative programs and, when needed, targeted therapeutic strategies should be deemed as an integral part of post-bariatric surgery clinical support.

Abstract
BACKGROUND Patients with obesity show evidence of increased levels of inflammation, oxidative stress and premature ageing. Telomere length (TL) is a key marker of cellular ageing, and patients with obesity often present shorter TL. Bariatric surgery (BS) is currently the most effective treatment for severe obesity. The aim of this systematic review was to explore whether the beneficial health effects observed after surgery in obese patients correspond to a restoration in TL or slower rates of shortening. As a secondary aim, we evaluated, at baseline and post-surgery, the relationship between TL and different factors that could play a role in TL changes along time. METHODS Searches for relevant articles were performed in MEDLINE, Web of Knowledge and SCOPUS. Prospective longitudinal studies that evaluated leukocyte TL in adult patients who had undergone BS were included. Data were extracted and evaluated by two independent researchers. The protocol was registered in PROSPERO with the number CRD42020197711. RESULTS Seven studies based on independent samples that fulfilled our inclusion criteria were included. Obese patients showed shorter telomeres compared to healthy individuals. Long-term studies (>2 years) seem to suggest an improvement in TL after surgery presumably due to the improvement of the inflammatory and oxidative levels of the patients induced by weight loss. CONCLUSION Studies seem to point towards a beneficial long-term effect of BS on TL recovery. However, the scarce number of studies and the heterogeneity in the variables analysed in the different cohorts make it difficult to draw a firm conclusion. More studies are needed to evaluate long-term changes to TL following BS.

Abstract
Until recently, weight loss in older obese people was feared because of ensuing muscle loss and frailty. Facing overall increasing longevity, high rates of obesity in older individuals (age ≥ 65 years) and a growing recognition of the health and functional cost of the number of obesity years, abetted by evidence that intentional weight loss in older obese people is safe, this approach is gradually, but not unanimously, being replaced by more active principles. Lifestyle interventions that include reduced but sufficient energy intake, age-adequate protein and micronutrient intake, coupled with aerobic and resistance exercise tailored to personal limitations, can induce weight loss with improvement in frailty indices. Sustained weight loss at this age can prevent or ameliorate diabetes. More active steps are controversial. The use of weight loss medications, particularly glucagon-like peptide-1 analogs (liraglutide as the first example), provides an additional treatment tier. Its safety and cardiovascular health benefits have been convincingly shown in older obese patients with type 2 diabetes mellitus. In our opinion, this option should not be denied to obese individuals with prediabetes or other obesity-related comorbidities based on age. Finally, many reports now provide evidence that bariatric surgery can be safely performed in older people as the last treatment tier. Risk-benefit issues should be considered with extreme care and disclosed to candidates. The selection process requires good presurgical functional status, individualized consideration of the sequels of obesity, and reliance on centers that are highly experienced in the surgical procedure as well as short-term and long-term subsequent comprehensive care and support.

Abstract
OBJECTIVE To evaluate the proportion of eligible individuals, within one health region in Ontario, who were referred for publicly funded medical and surgical weight-loss interventions (MSWLI). DESIGN A retrospective cohort study that used primary care data from the Canadian Primary Care Sentinel Surveillance Network (CPCSSN) and referral data from the Ontario Bariatric Network (OBN). SETTING Primary care practices within southeastern Ontario that contribute data to CPCSSN. PARTICIPANTS Patients with class II (body mass index [BMI] 35.0 to 39.9 kg/m2) or III (BMI ≥ 40 kg/m2) obesity who were eligible for referral to the OBN for MSWLI. MAIN OUTCOME MEASURES Primary care data about patients within the CPCSSN database were linked to referral records within the OBN database using 3 indirect identifiers to determine the proportion of patients with class II and III obesity who were referred to the OBN for MSWLI. An adjusted multivariate logistic regression model was used to determine the most significant predictors of referral. RESULTS Of the 87 276 patients within one health region in Ontario, 15 526 (17.8%) patients had class II or III obesity and were eligible for referral for MSWLI. Only 966 out of those 15 526 (6.2%) patients were actually referred for MSWLI. In the multivariate regression analysis, BMI had the strongest association with referral in terms of adjusted odds ratio (AOR), varying from 2.50 (95% CI 2.04 to 3.06) for a BMI of 40.0 to 44.9 kg/m2, to 5.15 (95% CI 4.21 to 6.30) for a BMI of 50.0 kg/m2 or greater. Referral was more likely for female than male patients (AOR = 2.18; 95% CI 1.86 to 2.57), those living rurally than for urban dwellers (AOR = 1.39; 95% CI 1.20 to 1.60), and those aged 30 to 39 (AOR = 1.61; 95% CI 1.24 to 2.09) and 40 to 49 (AOR = 1.53; 95% CI 1.18 to 1.98) compared with other age groups. CONCLUSION Within one health region in Ontario, the referral rate of patients with class II and III obesity for MSWLI was low. Our findings highlight the need for further research to understand and address the barriers to referral of patients with class II and III obesity for MSWLI.

Abstract
BACKGROUND Conflicting data have been published for bariatric surgery in older patients, with no long-term large-scale studies available. Our aim was to provide long-term (> 10 years) results on weight loss, metabolic outcomes, and quality of life in a large homogenous series of Roux-en-Y gastric bypass (RYGB) patients, according to age at baseline. PATIENTS AND METHODS All consecutive patients who underwent primary RYGB between 1999 and 2007, and therefore eligible for 10-year follow-up, were retrospectively analyzed. According to their age at baseline, they were divided into three groups: A (< 40 years), B (40-54 years), and C (≥ 55 years). Categorical variables were compared with the χ2 test and continuous variables with ANOVA. RESULTS Our series consisted of 820 patients, with a 10-year follow-up of 80.6%. Although group C (11% of all patients) had significantly more comorbidities at baseline, there was no difference in postoperative morbidity and mortality between groups. Weight loss was significantly less for group C patients up to the 7th postoperative year, but no difference remained thereafter. 10-year %total weight loss was 32.2, 32.9, and 32.3 respectively in groups A, B, and C. After 10 years, glycemic control and lipid profile improved similarly, rates of partial or complete remission of diabetes and hypertension were identical, and quality of life presented a significant improvement for all patients with no inter-group difference. CONCLUSION Our results suggest similar short- and long-term outcomes after RYGB for patients ≥ 55 years compared to younger ones; the relative benefit might even be higher for older patients, given their increased comorbidity at baseline.

Abstract
INTRODUCTION Severe obesity can lead to progressive kidney injury and chronic kidney disease (CKD). The current study aimed at determining whether preoperative kidney function level in patients with estimated glomerular filtration rate (eGFR) ≥30 mL/min affects weight loss after bariatric surgery. METHODS A total of 1958 bariatric patients underwent laparoscopic sleeve gastrectomy and gastric bypass from March 2013 to March 2017. The patients were categorized according to preoperative eGFR (30-59, 60-89, 90-124, and ≥ 125 mL/min). Changes in body mass index (BMI), percentage of total weight loss (TWL%), and percentage of excess weight loss (EWL%) were compared across the eGFR categories. Moreover, multivariable logistic regression analysis was used to evaluate the relationship between eGFR and insufficient weight loss (defined as not achieving 50% EWL at 12 months after surgery). RESULTS Preoperative eGFR was positively associated with unadjusted ΔBMI (P trend < 0.001), TWL% (P trend < 0.001), and EWL% (P trend = 0.007) after 12 months of surgery. However, these associations were no longer significant after multivariable adjustment. Further, univariate analysis demonstrated a positive relationship between preoperative eGFR and insufficient weight loss (odds ratio [OR] 1.38; 95% confidence interval [CI] 1.11-1.71; P = 0.004). By contrast, preoperative eGFR was not a predictor of insufficient weight loss in multivariable logistic regression analysis (OR 0.98; 95% CI 0.46-1.24; P = 0.886). CONCLUSION Although patients with lower preoperative eGFR experience less weight loss after bariatric surgery, preoperative kidney function does not appear to have an independent impact on postoperative weight loss in patients with eGFR ≥ 30 mL/min.

Abstract
IMPORTANCE There are high-quality randomized clinical trial data demonstrating the effect of bariatric surgery on type 2 diabetes remission, but these studies are not powered to study mortality in this patient group. Large observational studies are warranted to study the association of bariatric surgery with mortality in patients with type 2 diabetes. OBJECTIVE To determine the association between bariatric surgery and all-cause mortality among patients with type 2 diabetes and severe obesity. DESIGN, SETTING, AND PARTICIPANTS This retrospective, population-based matched cohort study included patients with type 2 diabetes and body mass index (BMI; calculated as weight in kilograms divided by height in meters squared) 35 or greater who underwent bariatric surgery from January 2010 to December 2016 in Ontario, Canada. Multiple linked administrative databases were used to define confounders, including age, baseline BMI, sex, comorbidities, duration of diabetes diagnosis, health care utilization, socioeconomic status, smoking status, substance abuse, cancer screening, and psychiatric history. Potential controls were identified from a primary care electronic medical record database. Data were analyzed in 2020. EXPOSURE Bariatric surgery (gastric bypass and sleeve gastrectomy) and nonsurgical management of obesity provided by the primary care physician. MAIN OUTCOMES AND MEASURES The primary outcome was all-cause mortality. Secondary outcomes were cause-specific mortality and nonfatal morbidities. Groups were compared through a multivariable Cox proportional Hazards model. RESULTS A total of 6910 patients (mean [SD] age at baseline, 52.04 [9.45] years; 4950 [71.6%] women) were included, with 3455 patients who underwent bariatric surgery and 3455 match controls and a median (interquartile range) follow-up time of 4.6 (3.22-6.35) years. In the surgery group, 83 patients (2.4%) died, compared with 178 individuals (5.2%) in the control group (hazard ratio [HR] 0.53 [95% CI, 0.41-0.69]; P < .001). Bariatric surgery was associated with a 68% lower cardiovascular mortality (HR, 0.32 [95% CI, 0.15-0.66]; P = .002) and a 34% lower rate of composite cardiac events (HR, 0.68 [95% CI, 0.55-0.85]; P < .001). Risk of nonfatal renal events was also 42% lower in the surgical group compared with the control group (HR, 0.58 [95% CI, 0.35-0.95], P = .03). Of the groups that had the highest absolute benefit associated with bariatric surgery, men had an absolute risk reduction (ARR) of 3.7% (95% CI, 1.7%-5.7%), individuals with more than 15 years of diabetes had an ARR of 4.3% (95% CI, 0.8%-7.8%), and individuals aged 55 years or older had an ARR of 4.7% (95% CI, 3.0%-6.4%). CONCLUSIONS AND RELEVANCE These findings suggest that bariatric surgery was associated with reduced all-cause mortality and diabetes-specific cardiac and renal outcomes in patients with type 2 diabetes and severe obesity.

Abstract
Purpose To analyze the effectiveness of vertical gastrectomy in the treatment of
obese patients, adherence to clinical follow-up and the influence of factors
such as gender and age. Methods This is a retrospective, observational and descriptive study, conducted with
patients undergoing vertical gastrectomy, operated at Hospital São Domingos,
between January 2016 and July 2018. Results Most patients undergoing vertical gastrectomy were female (n = 193, 72.28%)
and had a mean age of37.11 ± 8.96 years old. The loss of follow-up was
56.18%. Among adherent patients (n = 117; 43.82%), most patients were female
(n = 89; 76.07%) and had a mean age of 37.92 ± 9.85 years old. The mean body
mass index (BMI) of the adherents in the preoperative was 37.85 ± 3.72
kg/m2. Both BMI and excess weight (EW) showed a statistically
significant difference between pre- and postoperative period. Percentage of
excess weight loss (% EWL) was satisfactory for 96.6% of adherent patients.
Older patients had a statistically significant lower % EWL compared to the
other groups. Conclusions Vertical gastrectomy was effective in the treatment of obese patients, with
significant weight loss.

Abstract
INTRODUCTION Despite the abundance of data addressing the influence of patient's age on surgery-related complications, its impact on cardiometabolic outcomes following bariatric surgery has been overlooked. METHODS Retrospective unicentric study of 1,728 obese patients who underwent bariatric surgery between January 2010 and June 2015. Patients were divided in 3 age groups, according to their age at surgery: ˂40 (n = 751), 40-59 (n = 879), and ≥60 years (n = 98). Parameters with cardiometabolic impact, such as body anthropometric measures, lipid profile, and glycemic status, before and 24 months after surgery, were compared between these groups. A multiple linear regression was performed, adjusting differences between groups for sex, surgery type, and body mass index variation. RESULTS The group ˂40 years presented more weight loss (-35.4 ± 9.0 kg, p ˂ 0.001), greater BMI reduction (-15.8 ± 6.1 kg/m2, p ˂ 0.001), and larger changes in waist (-34 ± 13.8 cm, p ˂ 0.001) and hip circumferences (-28.7 ± 11.9 cm, p ˂ 0.05). The group of ≥60 years presented the heaviest reduction in fasting glucose (-17.7 ± 32.8 mg/dL, p ˂ 0.001) and HbA1c (0.7 ± 1.0, p ˂ 0.001), and also had a tendency to have the biggest changes in systolic blood pressure (-14.7 ± 18.7 mm Hg, p = 0.071). CONCLUSION Patients with ≥60 years benefit the most from bariatric surgery regarding cardiometabolic parameters, presenting heavier reductions in fasting glucose, as well as HbA1c and a tendency towards a higher decrease in systolic blood pressure. No clinically significant differences in lipid profile were observed between groups.

Abstract
BACKGROUND The incidence of obesity has been constantly growing and bariatric procedures are considered to be the most effective treatment solution for morbidly obese patients. The results of laparoscopic sleeve gastrectomy (LSG) may differ depending on patient's age, gender, preoperative body mass index (BMI) and physical activity. METHODS The aim of this study was to evaluate age-related differences in the outcome of LSG in terms of weight loss parameters, lipid and carbohydrate profile. The retrospective analysis of 555 patients who had undergone LSG was performed to compare the metabolic outcomes of surgery in individuals < 45 and ≥ 45 years old. Evaluation of weight loss parameters along with selected laboratory data was performed to demonstrate the results of LSG in 2 years follow-up. RESULTS Overall, 238 males and 317 females (43%/57%) with median age of 43 years and median preoperative BMI of 46.41 (42.06-51.02) kg/m2 were analyzed. Patients in both groups presented significant weight loss at 24 months after the surgery with comparable percentage of total weight loss (40.95% in < 45 years old group and 40.44% in ≥ 45 years old group). The percentage of excess weight loss (78.52% vs. 74.53%) and percentage of excess BMI loss (91.95% vs. 88.01%) were higher in patients < 45 years old. However, the differences were not statistically significant (p = 0.662, p = 0.788 respectively). Patients under 45 years old experienced faster decrease in fasting glucose level that was observed after only 3 months (109 mg/dl to 95 mg/dl in < 45 years old group vs. 103.5 mg/dl to 99.5 mg/dl in ≥ 45 years old group, p < 0.001). Both groups presented improvement of lipid parameters during the observation. However, patients < 45 years old achieved lower values of LDL at 3 and 12 months follow-up (115 mg/dl vs. 126 mg/dl, p = 0.010; 114.8 mg/dl vs. 122 mg/dl, p = 0.002). Younger group of patients also showed superior improvement of triglycerides level. CONCLUSIONS LSG results in significant weight loss in all patients regardless age. In turn, superior and faster improvement in lipid and carbohydrate profile is achieved in patients under 45 years old.

Abstract
BACKGROUND Mortality after bariatric surgery has been previously studied, but cohort selection bias, completeness of follow-up, and collection of confounders have limited the inference of results. OBJECTIVE To determine the association between bariatric surgery and all-cause mortality. DESIGN Population-based matched cohort study. SETTING Ontario, Canada. PARTICIPANTS 13 679 patients who underwent bariatric surgery from January 2010 to December 2016 and 13 679 matched nonsurgical patients. INTERVENTION Bariatric surgery. MEASUREMENTS The primary outcome was all-cause mortality, with cause-specific mortality as the secondary outcome. Patients were matched according to age, sex, body mass index, and diabetes duration. RESULTS 13 679 patients who underwent bariatric surgery were matched to 13 679 nonsurgical patients. After a median follow-up of 4.9 years, the overall mortality rate was 1.4% (n = 197) in the surgery group and 2.5% (n = 340) in the nonsurgery group, with a lower adjusted hazard ratio (HR) of overall all-cause mortality (HR, 0.68 [95% CI, 0.57 to 0.81]). Patients aged 55 years or older had an absolute risk reduction of 3.3% (CI, 2.3% to 4.3%), with a lower HR of mortality in the surgery group (HR, 0.53 [CI, 0.41 to 0.69]). Observed relative effects were similar across sex; however, the observed association in absolute terms was greater in men. Surgery also was associated with lower cardiovascular mortality (HR, 0.53 [CI, 0.34 to 0.84]) and lower cancer mortality (HR, 0.54 [CI, 0.36 to 0.80]). LIMITATION The observational design limits causal inference. CONCLUSION Bariatric surgery was associated with substantially lower all-cause, cardiovascular, and cancer mortality. The lowered observed mortality of surgery was significant across most subgroups. The largest absolute effects were for men and patients aged 55 years or older.

[PMID: 32106362 PMCID: PMC7719414 DOI: 10.5946/ce.2019.181] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/11/2019] [Revised: 10/31/2019] [Accepted: 11/05/2019] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND/AIMS Aspiration therapy (AT) involves endoscopic placement of a gastrostomy tube with an external device that allows patients to drain 30% of ingested calories after meals. Its efficacy for inducing weight loss has been shown. This study aimed to assess the effect of AT on obesity-related comorbidities. METHODS A meta-analysis of studies that assessed AT outcomes was conducted through December 2018. Primary outcomes were changes in comorbidities at 1 year following AT. Secondary outcomes were the amount of weight loss at up to 4 years and pooled serious adverse events (SAEs). RESULTS Five studies with 590 patients were included. At 1 year, there were improvements in metabolic conditions: mean difference (MD) in systolic blood pressure: -7.8 (-10.7 - -4.9) mm Hg; MD in diastolic blood pressure: -5.1 (-7.0 - 3.2) mm Hg; MD in triglycerides: -15.8 (-24.0 - -7.6) mg/dL; MD in high-density lipoprotein: 3.6 (0.7-6.6) mg/dL; MD in hemoglobin A1c (HbA1c): -1.3 (-1.8 - -0.8) %; MD in aspartate transaminase: -2.7 (-4.1 - -1.3) U/L; MD in alanine transaminase: -7.5 (-9.8 - -5.2) U/L. At 1 (n=218), 2 (n=125), 3 (n=46), and 4 (n=27) years, the patients experienced 17.8%, 18.3%, 19.1%, and 18.6% total weight loss (TWL), corresponding to 46.3%, 46.2%, 48.0%, and 48.7% excess weight loss (EWL) (p<0.0001 for all). Subgroup analysis of 2 randomized controlled trials (n=225) showed that AT patients lost more weight than did controls by 11.6 (6.5-16.7) %TWL and 25.6 (16.0-35.3) %EWL and experienced greater improvement in HbA1c and alanine transaminase by 1.3 (0.8-1.8) % and 9.0 (3.9-14.0) U/L. The pooled SAE rate was 4.1%. CONCLUSION Obesity-related comorbidities significantly improved at 1 year following AT. Additionally, a subgroup of patients who continued to use AT appeared to experience significant weight loss that persisted up to at least 4 years.

Surg Obes Relat Dis 2020; 16:1954-1960. [PMID: 32958371 DOI: 10.1016/j.soard.2020.07.037] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2020] [Revised: 07/05/2020] [Accepted: 07/27/2020] [Indexed: 11/25/2022]
Abstract
BACKGROUND Long-term (>5 yr) studies assessing outcomes after laparoscopic Roux-en-Y gastric bypass (LRYGB) using the Bariatric Analysis and Reporting Outcome System (BAROS) are limited. Evidence of predictors of failure long-term after LRYGB is also lacking. OBJECTIVES To compare BAROS scores at 5 and 10 years post LRYGB and to establish whether individual obesity-related co-morbidities are associated with suboptimal outcomes at these time points. SETTING Single bariatric unit. METHODS BAROS scores were analyzed in patients who were 5 years (group A) and 10 years (group B) post LRYGB. Obesity-related co-morbidities as predictors of failure of surgery (defined by % excess weight loss [%EWL] <50% or BAROS total score ≤1) were examined. Intergroup comparative analysis of outcomes and logistic regression modeling to determine predictors of weight loss failure were conducted. RESULTS A total of 88 patients were 5 years post LRYGB (group A), and 91 patients were 10 years post LRYGB (group B). A total of 52.3% (46/88) in group A and 54.9% (50/91) in group B had failure of weight loss defined by %EWL <50%. There were no significant differences in percentage of total weight loss, %EWL, or BAROS scores between the 2 groups (21.8% versus 22.0%, P = .897; 48.5% versus 47.1%, P = .993; and 3.7 versus 3.3, P = .332, respectively). No individual obesity-related co-morbidity at time of surgery was associated with suboptimal outcomes (%EWL <50% or BAROS total score ≤1) at 5 years or 10 years after LRYGB. CONCLUSIONS Long-term outcomes assessed by the BAROS score appear sustainable between 5 and 10 years after LRYGB surgery, and weight loss achieved at 5 years is maintained at 10 years. Preoperative presence of specific obesity-related co-morbidities was not associated with failure of surgery long-term.

Abstract
BACKGROUND While patients are becoming older and the prevalence of obesity increases worldwide, literature on the impact of age on outcomes after laparoscopic Roux-en-Y gastric bypass (LRYGB) is scarce. The balance between surgical risks and clinical benefits of LRYGB are unclear in relation to age. OBJECTIVES To evaluate the impact of age on the risk of postoperative complications, postoperative weight loss, and remission of co-morbidities for patients who underwent LRYGB. SETTING A high-volume center for bariatric surgery. METHODS A retrospective analysis of 582 patients who underwent LRYGB was performed. Linear logistic regression analyses were performed to evaluate the potential impact of age on the postoperative percentage of total weight loss (%TWL). Multivariable binary logistic regression analyses were performed to evaluate whether age was independently associated with the risk of postoperative complications and likelihood of remission of co-morbidities (hypertension, diabetes, and dyslipidemia). In addition, these outcomes were descriptively analyzed for the following 3 age groups: the young (18-39 yr), the middle aged (40-59 yr), and the elderly (≥60 yr). RESULTS Patients with hypertension were more prone to developing postoperative complications (odds ratio 2.435, 95% confidence interval: 1.241-4.777) and no other factors were found to be associated with the risk of postoperative complications. Older age was significantly associated with lower %TWL at a postoperative follow-up of 6 (ß = -.117, P = .004), 12 (ß = -.177, P < .001), and 36 months (ß = -.169, P = .001), but not at 60 months (ß = -.097, P = .161). Nonetheless, a %TWL of 30% was observed in patients who were >60 years at the time of surgery. Age was not associated with the likelihood of co-morbidity resolution after LRYGB. The remission of hypertension was less likely in patients with co-existence of diabetes (odds ratio .334, 95% confidence interval: .136-.821) and in patients with a longer length of postoperative follow-up (odds ratio .982, 95% confidence interval: .966-.998). CONCLUSIONS Although older age seems to be associated with lower postoperative %TWL, elderly patients can still achieve a %TWL of 30% after LRYGB. In this study, age was not found to be an independent predictor of postoperative complications nor the likelihood of co-morbidity resolution. Therefore, older age alone should not be an absolute contraindication for LRYGB.

Abstract
PURPOSE to assess the long-term benefits of bariatric surgery in super-obese (body mass index [BMI] ≥ 50) and in elderly obese (age > 60 years) populations. METHODS one hundred and twenty one patients who underwent laparoscopic Roux-en-Y gastric bypass or laparoscopic sleeve gastrectomy in a university hospital were retrospectively subdivided into the following groups: BMI < 50 vs ≥ 50 and age < 60 vs ≥ 60 years. Weight loss, body composition and comorbidity outcomes were registered after one and six months and one, two, three and five years with 100%, 93%, 89%, 80%, 75% and 60% successful follow-up. RESULTS the percentage of excess BMI loss (%EBMIL) was comparable between BMI groups and age groups and the difference in the long-term follow up was not statistically significant (p > 0.05). Complication rates, comorbidity resolution, reduction in body fat and increase in fat-free mass were comparable between BMI groups and age groups. Gastric bypass resulted in a greater weight loss compared to sleeve gastrectomy. The % EBMIL was 65.2% vs 46.7% (p = 0.002), 65.8% vs 44.9% (p = 0.004), 64.4% vs 30.5% (p = 0.001), 55.6% vs 17.6% (p = 0.016) at one, two, three and five years postoperative, respectively. Similarly, in the super-obese group, weight loss was more pronounced after gastric bypass versus sleeve gastrectomy. CONCLUSIONS bariatric surgery in super-obese and elderly populations is an effective and safe weight loss measure with a good comorbidity resolution in the long-term. Gastric bypass is superior to sleeve gastrectomy in terms of long-term weight loss and comorbidity resolution in all the groups investigated.

Abstract
BACKGROUND Currently, bariatric surgery is the most effective treatment for severe obesity and its metabolic complications; however, 15-35% of the patients that undergo bariatric surgery do not reach their goal for weight loss. The aim of this study was to determine the proportion of patients that didn't reach the goal of an excess weight loss of 50% or more during the first 12 months and determine the factors associated to this failure. METHODS We obtained the demographic, anthropometric and biochemical information from 130 patients with severe obesity who underwent bariatric surgery in our institution between 2012 and 2017. We used self-reports of physical activity, caloric intake and diet composition. An unsuccessful weight loss was considered when the patient lost < 50% or more of the excess weight 12 months after surgery. We compared the characteristics between the successful and unsuccessful groups in order to find the factors associated with success. RESULTS We included 130 patients (mean age 48 ± 9 years, 81.5% were women). One year after surgery, 26 (20%) had loss < 50% EBW. Unsuccessful surgery was associated with an older age, previous history of hypertension, abdominal surgery or depression/anxiety, also the number of comorbidities and unemployment affected the results. These patients loss enough weight to improve some of their comorbidities, but they are more prone to regain weight 2 years after surgery. CONCLUSIONS A fifth of the patients undergoing bariatric surgery may not lose enough weight to be considered successful by current standards. Some patients may benefit from the surgery in the short term, but they are more likely to regain weight after 2 years. The factors influencing this result are still controversial but may be population-specific. Early detection of the patients that are more likely to fail is imperative to establish additional therapeutic strategies, without denying them the opportunity of surgery or waiting for weight re-gain to occur.

Abstract
BACKGROUND Emerging evidence suggests that the FK506 binding protein 51 (FKBP5/FKBP51), encoded by the FKBP5 gene, influences weight and metabolic regulation. The T allele of a functional polymorphism in FKBP5 (rs1360780), has been associated with the expression of FKBP51 and weight loss after bariatric surgery. OBJECTIVE To examine the role of the FKBP5 rs1360780 polymorphism in relation to age, sex, and type of surgery in weight loss after bariatric surgery in patients with severe obesity. SETTING University Hospital in Spain METHODS: A cohort of 151 obese patients submitted to Roux-en-Y gastric bypass (62.3%) and sleeve gastrectomy (37.7%) were followed-up during 24-months (t24m; loss to follow-up: 0%). During the postoperative period body mass index (BMI) and percentage of excess and total weight loss were evaluated. RESULTS The BMI analysis showed an effect of the interaction FKBP5 genotype by sex (P = .0004) and a tendency to the interaction genotype by surgery (P = .048), so that men carrying the T allele had higher BMI at t24m than those without the T allele, and T-allele carriers that underwent sleeve gastrectomy had higher BMI at t24m than the noncarriers. Additionally, we found an interaction between FKBP5 and age for the percentage of excess weight loss and BMI (P = .0005 and P = 1.5e-7, respectively), whereby individuals >48 years with the T allele displayed significant differences for the analyzed variables at t24m compared with the homozygotes for the alternate C allele showing lower weight loss. CONCLUSION FKBP5 rs1360780 genotype has specific effects on weight loss outcomes after bariatric surgery depending on sex, age, and type of surgery, suggesting worse results in older males carrying the T allele who have undergone sleeve gastrectomy.

Abstract
Background: The impact of age on complications following bariatric surgery remains unclear. Research is therefore warranted among previously unstudied populations of bariatric surgery patients. The aim of the current study was to assess the impact of age on postoperative complications following bariatric surgery in Saudi Arabia. Methods: This retrospective study included 301 patients who underwent bariatric surgery between January 2011 and July 2016. Patients were classified into three groups according to age: < 25 years; 25–36 years; and >36 years. Primary outcomes were determined by identifying the number of complications reported during a period of 180 days. The negative binomial model was used to assess the relationship between age and the high rate of postoperative complications following adjustment for confounding variables. Results: The incidence of overall complications was 10.1% in the < 25-year age group, 15% in the 25–36-year age group, and 24.2% in the >36-year age group. After adjusting for confounding variables, it was discovered that the risk of postoperative complications increases with age. The risk was higher in the >36-year age group than in the >25-year age group [adjusted relative rate (aRR) = 2.35; 95% confidence interval (CI) = 1.046–5.290; p = 0.039]. Diabetes (aRR = 3.27), adjustable gastric bands (aRR = 3.40), and a more lengthy hospital stay (aRR = 1.23) were associated with increased rates of postoperative complications. Conclusion: Age is independently associated with a high rate of postoperative complications following bariatric surgery. The results showed that patients with diabetes, those using adjustable gastric bands, and those with longer length of hospital stay had significantly higher incidence of postoperative complications. These findings indicate the need for risk stratification tools to evaluate patients as candidates for bariatric surgery and to use as a guide for identifying optimal preoperative factors.

Abstract
BACKGROUND Bariatric surgery is the most effective modality to treat obesity and obesity-related comorbidities. This study sought to utilize the MBASQIP® Data Registry to analyze the impact of age at time of surgery on outcomes following sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) procedures. METHODS The MBSAQIP® Data Registry for patients undergoing SG or RYGB procedures between 2015 and 2016 was reviewed. Patients were divided into 4 age groups [18-44; 45-54; 55-64; > 65 years]. Minimal exclusions for revisional and/or emergency surgery were selected and combination variables created to classify complications as major or minor. A comorbidity index was constructed to include diabetes, gastroesophageal reflux disease (GERD), obstructive sleep apnea (OSA), and prior cardiac surgery. Univariate and multivariate logistic regression analyses were performed to compare age stratifications to the young adult (18-45 years) cohort. RESULTS Of 301,605 cases, 279,419 cases (71.2% SG) remained after applying exclusion criteria (79.2% female, mean BMI 45.5 ± 8.1 kg/m2, 8.9% insulin-dependent diabetics). Mean age was 44.7 ± 12.0 years (51.3% 18-44 years; 26.9% 45-54 years; 16.3% 55-64 years; 5.5% > 65 years). A univariate analysis demonstrated preoperative differences of lower BMI with increasing age concomitant with increasing frequency of RYGB and a higher comorbidity index (p < 0.0001 vs. 18-45 years). At age > 45 years, major complications and 30-day mortality increased independent of procedure type (p < 0.0001). A multivariate analysis controlling for comorbidity indices demonstrated increasing age (> 45 years) increased risk for major complications and mortality. CONCLUSION Overall, bariatric surgery (SG or RYGB) remains a low mortality risk procedure for all age groups. However, all age group classifications > 45 years had higher incidence of major complications and mortality compared to patients 18-45 years (despite older individuals having lower preoperative BMI) indicating delaying surgery is detrimental.

Preoperative liking and wanting for sweet beverages as predictors of body weight loss after Roux-en-Y gastric bypass and sleeve gastrectomy. Int J Obes (Lond) 2019; 44:1350-1359. [PMID: 31641214 PMCID: PMC7174088 DOI: 10.1038/s41366-019-0474-1] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2019] [Revised: 09/18/2019] [Accepted: 09/27/2019] [Indexed: 12/16/2022]
Abstract
Background/objectives: Patients who receive Roux-en-Y gastric bypass (RYGB) lose more weight than those who receive vertical sleeve gastrectomy (VSG). RYGB and VSG alter hedonic responses to sweet flavor, but whether baseline differences in hedonic responses modulate weight loss after RYGB or VSG remains untested. Participants/methods: Male and female candidates (n=66) for RYGB or VSG were recruited and tested for their subjective liking and wanting ratings of sucrose solutions and flavored beverages sweetened with aspartame. Participants were classified by unsupervised hierarchical clustering for their liking and wanting ratings of sucrose and aspartame. Participant liking ratings were also used in a supervised classification using pre-established categories of liking ratings (liker, disliker, and inverted u-shape). Effects of categories obtained from unsupervised or supervised classification on body weight loss and their interaction with surgery type were analyzed separately at 3 and 12 months after surgery using linear models corrected for sex and age. Results: RYGB participants lost more body weight compared to VSG participants at 3 and 12 months after surgery (P < 0.001 for both time points). Unsupervised clustering analysis identified clusters corresponding to high and low wanting or liking ratings for sucrose or aspartame. RYGB participants in high-wanting clusters based on sucrose, but not aspartame, lost more weight than VSG at both 3 (P = 0.01) and 12 months (P = 0.03), yielding a significant cluster by surgery interaction. Categories based on supervised classification using liking ratings for sucrose or aspartame showed no significant effects on body weight loss between RYGB and VSG participants. Conclusions: Classification of patients into high/low wanting ratings for sucrose before surgery can predict differential body weight loss after RYGB or VSG in adults and could be used to advise on surgery type.

Abstract
BACKGROUND Even though risks are higher and long-term results may be less favorable, the elderly obese can still benefit from bariatric surgery. Whether the higher surgical risk is worth the benefits is yet to be determined. MATERIALS AND METHODS We reviewed our database and identified all patients aged 65 or older who underwent sleeve gastrectomy between May 2010 and November 2015. We documented patient demographics, obesity-related comorbidities, body mass index (BMI) before and after the procedure, percent excess weight loss, comorbidity improvement or resolution, length of follow-up, postoperative complications, re-operations, and length of hospital stay. We compared our study group to a control group of sleeve gastrectomy patients under the age of 65. RESULTS Sixty-six patients (mean age 67.6 ± 2.6 years) underwent laparoscopic sleeve gastrectomy. Patients achieved an average of 53.5% excess BMI loss (EBMIL) after 21 months of follow-up. EBMIL was inferior to that achieved by the control group (EBMIL 77.3%, p < 0.0001). Elderly patients showed significant improvement or resolution in all obesity-related comorbidities. Complication and re-operation rates were similar between the 2 groups. CONCLUSION In an elderly population, laparoscopic sleeve gastrectomy is safe and effective, yet weight loss outcomes are more modest when compared to a younger surgical population. Carefully selected elderly patients can benefit from bariatric surgery.

Abstract
INTRODUCTION There is a paucity of literature describing the association of age with the risk of adverse events following bariatric surgery. The purpose of this study is to investigate the association of age with 30-day morbidity and mortality following laparoscopic bariatric surgery using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database. METHODS All adult patients undergoing laparoscopic Roux-en-Y gastric bypass (RNGYB) or sleeve gastrectomy (SG) were identified within the MBSAQIP database. Patients were divided into five equal age quintiles. Binary outcomes of interest, including cardiac, pulmonary, wound, septic, clotting, and renal events, in addition to the incidence of related 30-day unplanned reintervention, related 30-day mortality, and a composite morbidity and mortality outcome were compared across the age quintiles and procedures. RESULTS A total of 266,544 patients met inclusion criteria. Older age was associated with an increased risk of all morbidity outcomes except venous thromboembolism events, 30-day mortality, and the composite morbidity and mortality outcome. Patients who underwent Roux-en-Y gastric bypass had worse outcomes per quintile for almost every outcome of interest when compared to patients who underwent sleeve gastrectomy. CONCLUSION Older patients and patients who undergo Roux-en-Y gastric bypass are at an increased risk of perioperative morbidity and mortality following laparoscopic bariatric surgery. Additional studies are needed to determine the association of age with long-term weight loss and cardiometabolic comorbidity resolution following bariatric surgery in order to determine if the increased perioperative risk is offset by improved long-term outcomes in older patients undergoing bariatric surgery.

Abstract
PURPOSE Older age (> 60) has been considered a relative contraindication for bariatric surgery due to increased complication risk. This study examined the risks and benefits of bariatric surgery for patients older than 60 years in Canadian population. METHODS This was a retrospective cohort study of the Ontario Bariatric Registry: a database recording peri-operative and post-operative outcomes of publicly funded bariatric surgeries across the province. Patients who completed 1 year follow-up, who underwent laparoscopic gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG) between January 2010 and May 2013, were divided into older (> 60) and younger (> 60) cohorts, and outcomes were compared. RESULTS Between January 2010 and May 2013, 3166 registry patients underwent LRYGB or LSG and completed 1-year follow-up. Of these, 204 (6.5%) were older than 60 years, with 175 (85.8%) undergoing LRYGB and 29 (14.2%) LSG. Demographics were similar, except for a higher number of males in the older group (59 (28.9%) versus 452 (15.3%) (p < 0.001)). No significant difference in complication rate was noted (15% for younger cohort versus 13.8% (p = 0.889)). The average percentage of excess weight loss was significantly higher in the younger population (60.72% versus 56.25% (p < 0.05)) overall, however not significantly in the LSG group. Reduction in medication use post-surgery for management of co-morbidities was significantly higher in the older patients (- 0.91 versus - 2.03 (p < 0.001)). CONCLUSION The older cohort who underwent LRYGB or LSG was at no greater risk for intra-operative and post-operative complications and showed greater reduction in medication use post-surgery when compared to the younger cohort.

Abstract
BACKGROUND Although bariatric surgery is an effective treatment for obesity, utilization of bariatric procedures in older adults remains low. Previous work reported higher morbidity in older patients undergoing bariatric surgery. However, the generalizability of these data to contemporary septuagenarians is unclear. OBJECTIVES We sought to evaluate differences in 30-day outcomes, 1-year weight loss, and co-morbidity remission after bariatric surgery among 3 age groups as follows: <45 years, 45-69 years, and ≥70 years. SETTING Statewide quality improvement collaborative. METHODS Using a large quality improvement collaborative, we identified patients undergoing sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) between 2006 and 2018. We used multivariable logistic regression models to evaluate the association between age cohorts and 30-day outcomes, 1-year weight loss, and co-morbidity remission. RESULTS We identified 641 septuagenarians who underwent SG (68.5%) or RYGB (31.5%). Compared with 45-69 year olds, septuagenarians had higher rates of hemorrhage (5.1% versus 3.1%; P = .045) after RYGB and higher rates of leak/perforation (.9% versus .3%; P = .044) after SG. Compared with younger patients, septuagenarians lost less of their excess weight, losing 64.8% after RYGB and 53.8% after SG. Remission rates for diabetes and obstructive sleep were similar for patients aged ≥70 years and 45-69 years. CONCLUSIONS Bariatric surgery in septuagenarians results in substantial weight loss and co-morbidity remission with an acceptable safety profile. Surgeons with self-imposed age limits should consider broadening their selection criteria to include patients ≥70 years old.

Abstract
BACKGROUND The increase in life expectancy along with the obesity epidemic has led to an increase in the number of older patients undergoing bariatric surgery. There is conflicting evidence regarding the safety of performing bariatric procedures on older patients. OBJECTIVE The purpose of this study was to compare the safety of laparoscopic sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) for older patients (>65 yr). SETTING Nationwide analysis of accredited centers. METHODS The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program 2015 to 2017 database was used to identify nonrevisional laparoscopic RYGB and SG procedures. Comparisons were made based on patient age. Clinical outcomes included postoperative events and mortality. RESULTS There was a total 13,422 and 5395 matched pairs for SG and RYGB in comparing patients aged 18 years to those aged 65 and >65 years, respectively, and 5395 matched RYGB and SG procedures performed in patients >65 years. The complication rate was higher in older patients undergoing RYGB compared with SG (risk difference = 2.39%, 95% confidence interval: 1.57%-3.21%, P < .0001). When comparing older to younger patients, the older group had a higher complication rate for SG but not for RYGB (SG: risk difference = 1.01%, 95% confidence interval: .59%-1.43%, P < .0001, RYGB: risk difference = .59%, 95% confidence interval: -.29% to 1.47%, P = .2003). CONCLUSIONS Overall complication rates of bariatric surgery are low in patients >65 years. SG appears to have a favorable safety profile in this patient population compared with RYGB. The overall complication rate for RYGB is not significantly different between the older and younger groups.

Abstract
In an era of rising obesity and an aging population, there are conflicting data regarding outcomes of laparoscopic weight loss surgery in older Americans. The aim of this study was to characterize the short-term outcomes of laparoscopic weight loss surgery in the elderly. The ACS NSQIP database was queried for obese patients aged ≥40 years undergoing laparoscopic Roux-en-Y gastric bypass or sleeve gastrectomy. Patients were subdivided into age groups: 40 to 49, 50 to 59, 60 to 64, 65 to 69, and ≥70 years, and compared with univariate and multivariate analyses. Fifty-three thousand five hundred thirty-three patients were identified. Roux-en-Y gastric bypass was performed in 57.5 per cent of cases and was more common than sleeve gastrectomy in all age groups ( P < 0.05). Comorbidities increased significantly with increasing age. There was an increase in minor (4.6% vs 9.1%; P < 0.0001) and major complications (2.2% vs 6.3%; P < 0.0001), and 30-day mortality (0.1% vs 0.5%; P = 0.0001) between the 40 to 49 and ≥70 years age groups. Increased age was independently associated with major complications. Mortality also increased with age. Older patients undergoing laparoscopic weight loss surgery have increased morbidity and mortality. When controlling for comorbidities, increases in age continued to impact major and minor complications and mortality.

Abstract
BACKGROUND Carotid intima-media thickness (CIMT) is increasingly used as a prognostic indicator for early atherosclerosis and the development of cardiovascular disease. The objective of this study is to assess the exact effects of bariatric surgery on CIMT reduction in different age groups. METHODS CIMT was measured just proximal to the bifurcation of the carotid artery in 166 patients with mean body mass index of 43.4 kg/m2 before and at 6 and 12 months after bariatric surgery. Preoperative CIMT and Framingham Risk Score (FRS) were compared to measurements at 6 and 12 months, postoperatively. Impact of age on CIMT change and cardiovascular risk reduction was analyzed. RESULTS Median follow-up was 12 months; 12% were lost to follow-up. Mean CIMT values at 12 months after bariatric surgery were significantly lower compared to baseline (0.619 vs. 0.587 mm, p = 0.005 in women and 0.675 vs. 0.622 mm, p = 0.037 in men, respectively), and these effects were statistically significant in all age groups. The mean reduction of CIMT for patients < 50 years at 12 months was 0.043 mm (- 7.0%), while CIMT was reduced with 0.013 mm for patients ≥ 50 years (- 1.9%, p = 0.022). At 12 months after bariatric surgery, FRS had decreased with 52% in patients < 50 years as compared with 35% in patients ≥ 50 years (p = 0.025). CONCLUSIONS Bariatric surgery resulted in a significant CIMT decrease in patients with morbid obesity in all evaluated age categories. These beneficial effects of bariatric surgery were more pronounced in younger patients, while cardiovascular risk reduction by bariatric surgery appeared inferior in patients of 50 years and older.

Abstract
BACKGROUND People are living longer than they were expected to 2 decades ago. Increased life expectancy and reduced mortality encompasses a simultaneous increase in the number of older adults with obesity that entails an increase of co-morbidities, such as diabetes, hypertension, cancer, and many other diseases. The aim of our study was to compare the outcomes of bariatric surgery in patients age ≥65 in comparison with younger patients. METHODS This retrospective study compares bariatric surgeries performed in a private institution between the years 2013 and 2015. The study included 9044 patients divided into an older group (451 patients) and the younger group (8593 patients). RESULTS In the younger group, bariatric surgery is distributed as follows: 77.68% sleeve gastrectomy, 12.72% gastric banding, 9.27% gastric bypass, and .33% duodenal switch or biliopancreatic diversion; in the older group: 70.51% sleeve gastrectomy, 15.08% gastric bypass, 13.97% gastric band, and .44% biliopancreatic diversion. In the control group 550 cases (6.4%) underwent revisional surgery; 64 cases (14.10%) underwent revision in the older group. Older patients lost less excess weight than younger patients (72.44% versus 86.11%, respectively). Older patients presented higher rates of complications (8.42% versus 5.59%), co-morbidities (77.60% versus 55.45%), and revisions (1.33% versus .77%). There was no statistical difference in hospital stay between older group and control group (2.27 versus 2.23, respectively). When performing a Clavien-Dindo classification, we demonstrated significant differences in class 3B and 4A and no differences in other classes. Two deaths occurred in the control group. Diabetes, fatty liver, and sleep apnea have been improved or remitted in >90% of patients in both groups, hypertension and hyperlipidemia by >80%, and hyperuricemia and ischemic heart disease were improved or resolved in >70% of the patients CONCLUSIONS: Bariatric surgery in the elderly has more complications, but it can still be considered safe.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) represents the most performed bariatric surgical procedure worldwide. Morbid Overweight in elderly patients is becoming a significant health problem even in Italy. As well as in younger age groups, bariatric surgery could be indicated even in this subset of patients. However the advantages and results of LSG in patients over 60 years old have received minimal attention. METHODS The records of 375 patients underwent LSG between 2008 and 2016 were reviewed. In the entire series 18 patients were aged 60 years or older at the time of surgery. Since a 3 years follow-up was available for 12 patients out of the 18 aged over 60 we included in the study only these. General epidemiologic data, clinical findings, BMI and comorbidities surgical treatment and follow-up data were collected; postoperative measurements such as operative time, intraoperative complications, mortality rate, length of stay, incidence of early and late complications, Body mass Index (BMI), excess weight loss rate (EWL%) and comorbidities resolution were also recorded. RESULTS LSG was successfully performed for all geriatric patients. Global complications rate was 16.6% At 3 years mean BMI was 34.4±3.8 with a mean EWL% 66.1±31.9. Postoperative resolution of obesity comorbidities was observed; Hypertension (71.4%), type 2 Diabetes Mellitus (T2DM) (50.0%), obstructive sleep apnea syndrome (OSAS) (66.6%) respectively. No intraoperative complications or mortality were recorded. CONCLUSIONS LSG offered cure in geriatric patients affected by morbid obesity for weight loss and comorbidities resolution. Larger studies are necessary to analyze and minimize the incidence of postoperative complications associated to this surgical procedure in elderly patients.

[PMID: 30056048 DOI: 10.1016/j.soard.2018.06.012] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2018] [Revised: 05/16/2018] [Accepted: 06/05/2018] [Indexed: 11/24/2022]
Abstract
BACKGROUND Young adults display particularly poor weight loss in behavioral obesity treatment; nonetheless, they have seldom been included in bariatric research. OBJECTIVES To compare weight loss, adverse events, and loss to follow-up in young (18-25 yr) versus older (≥26 yr) adults up to 5 years after Roux-en-Y gastric bypass. SETTING Nationwide, register-based study, Sweden. METHODS Prospective registry data (Scandinavian Obesity Surgery Register) were analyzed in young (22.2 yr [standard deviation (SD): 2.1], 81.6% women, mean body mass index 43.7 kg/m2 [SD: 5.4]) and older (42.6 years [SD: 9.6], 82.0% women, mean body mass index 43.4 kg/m2 [SD: 5.0]) adults undergoing Roux-en-Y gastric bypass. Groups were matched for body mass index, sex, and year of surgery. Regression analyses and mixed models were used to compare outcomes between groups. RESULTS A total of 369 young (37.0% of eligible) and 2210 older (46.1%) adults attended the 5-year follow-up. At this time, weight loss was 31.8% in young and 28.2% in older adults (P < .001), with a serious adverse event (Clavien-Dindo ≥3b) being reported in 52 (14.1%) young and 153 (6.9%) older adults (odds ratio = 2.06, 95% confidence interval: 1.45-2.92, P < .001). Loss to follow-up was higher in young versus older adults throughout the study period (range of relative risk = 1.16-1.89, P < .001). CONCLUSIONS While young adults displayed at least equal weight loss as older adults, rates of adverse events were approximately doubled, and loss to follow-up rates were higher. Future studies on the significance of and the etiology behind the higher incidence of serious adverse events are needed. Intensified clinical contact post Roux-en-Y gastric bypass should have the potential to further improve outcomes in young adults.

Surg Obes Relat Dis 2018; 14:1276-1282. [PMID: 29807868 DOI: 10.1016/j.soard.2018.04.008] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2017] [Revised: 03/07/2018] [Accepted: 04/16/2018] [Indexed: 11/17/2022]
Abstract
BACKGROUND An increase in the prevalence of obesity and longer life expectancy has resulted in an increased number of candidates over the age of 60 who are pursuing a bariatric procedure. OBJECTIVE The aim of this study was to assess the safety of laparoscopic Roux-Y gastric bypass (LRYGB) compared to laparoscopic sleeve gastrectomy (LSG) in patients aged 60 years or older. SETTING University Hospital, United States METHODS: Preoperative characteristics and 30-day outcomes from the MBSAQIP 2015 were selected for all patients aged 60 years or older who underwent a LSG or LRYGB. LRYGB cases were closely matched (1:1) with LSG patients by age (±1 year), BMI (±1 kg/m2), gender, preoperative steroid or immunosuppressant use, preoperative functional health status and comorbidities including: diabetes, gastroesophageal reflux disease, hypertension, hyperlipidemia, venous stasis, sleep apnea and history of severe chronic obstructive pulmonary disease. RESULTS A 3371 matched pairs were included in the study. The mean operative time in LRYGB was significantly longer in comparison to LSG patients (122 vs 84 min., P<0.001). Patients after LRYGB had a significantly increased anastomotic leakage rate (1.01% vs 0.47 %, p = 0.011), 30-day readmission rate (6.08% vs 3.74%, p < 0.001) and 30-day reoperation rate (2.49% vs 0.89%, p < 0.001) The length of hospital stay was longer in LRYGB. Mortality and bleed rate was comparable. CONCLUSIONS LRYGB and LSG in patients aged 60 years or older are relatively safe in the short term with an acceptable complication rate and low mortality. However, LRYGB is more challenging and is associated with significantly increased rates of leakage events, 30-day reoperation, 30-day readmission, longer operative time and longer hospital stay.

Abstract
BACKGROUND Numerous studies have established the effectiveness of Roux-en-Y gastric bypass (RYGB) for weight loss and co-morbidity amelioration. However, its safety and efficacy in elderly patients remains controversial. OBJECTIVES To evaluate outcomes in patients aged ≥60 years who underwent RYGB compared with nonsurgical controls with the hypothesis that RYGB provides weight loss benefits without differences in survival. SETTING University-affiliated tertiary center. METHODS All patients who underwent RYGB from 1985 to 2015 were identified and divided into elderly (age ≥60) and nonelderly (age <60) groups. A nonsurgical elderly control population was identified using a clinical data repository of outpatient visits to propensity match elderly patients 4:1 on demographic characteristics, co-morbidities, and relevant preoperative substance/medication use. Unpaired appropriate univariate analyses compared each stratified group. Kaplan-Meier survival curves were fitted based on social security death data. RESULTS A total of 2306 patients underwent RYGB. The 107 elderly patients had lower median body mass index (47.0 versus 49.9; P = .007) and higher rates of co-morbidities. Rates of complications did not differ between elderly and nonelderly patients. Elderly surgical patients were propensity matched 4:1 (10,044 controls) yielding 428 well-matched nonsurgical controls. The elderly group demonstrated significant percent reduction in excess body mass index compared with the control group (81.8% versus 10.3%; P < .001). Kaplan-Meier survival analysis with log-rank test demonstrated no difference in midterm survival (P = .63). CONCLUSIONS A significant weight reduction benefit was identified after RYGB in elderly patients without a difference in midterm survival compared with propensity-matched controls, suggesting RYGB is a safe and efficacious weight loss strategy in the elderly.

Abstract
An expert committee was appointed by the German Society for General and Visceral Surgery to develop a panel of appropriate quality indicators to collate the quality of results, indications and structure in metabolic and bariatric surgery. This entailed assimilating the available evidence (systematic literature search), results from the national registry of the society (StuDoQ|MBE) and specific socioeconomic aspects (e. g. severely limited access to metabolic and bariatric surgery in Germany). These quality parameters were to be incorporated into the national guidelines and the rules of procedure for certification in the future. The committee concluded that mortality, MTL30 and severe complications needing intervention (Clavien-Dindo ≥ 3b) are suitable indicators to measure surgical outcome quality due to their relevance, scientific soundness and practicability. As a systematic follow-up is mandatory after bariatric surgery, a minimum follow-up quota is now required using reported quality of life data as an indicator of process quality. As intestinal bypass procedures have been shown to be superior in the treatment of type 2 diabetes, these procedures should be offered to eligible patients and also be performed. The proposed threshold values based on the results of the available literature and StuDoQ registry are to be considered as preliminary and need to be validated and adjusted if necessary in the future. The StuDoQ|MBE is considered a valuable tool to gather this information and also represents the appropriate infrastructure for the collation of relevant risk adjustors.

Abstract
BACKGROUND The objective of this study was to analyze the factors associated with change in body mass index (BMI) and with percentage of excess weight loss (%EWL) in patients undergoing Roux-en-Y gastric bypass (RYGB). The following factors were analyzed: sex, age, surgical access (laparotomy vs. laparoscopy), preoperative BMI, waist circumference (WC), type 2 diabetes mellitus (T2DM), high blood pressure, and dyslipidemia. METHODS Retrospective cohort study using a convenience sample of 2070 patients of both sexes, aged 18 to 65 years, undergoing RYGB between 2000 and 2013. The outcomes of interest were BMI and %EWL at 0, 6, 12, 18, 24, 30, 36, 42, 48, 54, and 60 months after RYGB. RESULTS After 36, 48, and 60 months, approximately 50 % of patients had BMI >30 kg/m(2). As for %EWL, 60-month results were poor for 17 % of patients (%EWL <50 %), good for 40 % of patients (%EWL 50-75 %), very good for 24 % of patients (%EWL from >75-90 %), and excellent for 19 % of patients (%EWL >90 %). The four most significant predictors of BMI change 60 months after RYGB (in descending order of magnitude) were preoperative BMI, preoperative WC, surgical access, and age; and of %EWL, surgical access, preoperative BMI, preoperative WC, and age. CONCLUSIONS After 60 months of follow-up, the most relevant predictors of weight loss after RYGB were lower preoperative BMI and WC, videolaparoscopy as surgical access, and younger age. Further studies must be carried out to elucidate the impact of these factors on RYGB outcomes.

Abstract
Aging is associated with progressive white adipose tissue (WAT) enlargement initiated early in life, but the molecular mechanisms involved remain unknown. Here we show that mitochondrial complex IV (CIV) activity and assembly are already repressed in white adipocytes of middle-aged mice and involve a HIF1A-dependent decline of essential CIV components such as COX5B. At the molecular level, HIF1A binds to the Cox5b proximal promoter and represses its expression. Silencing of Cox5b decreased fatty acid oxidation and promoted intracellular lipid accumulation. Moreover, local in vivo Cox5b silencing in WAT of young mice increased the size of adipocytes, whereas restoration of COX5B expression in aging mice counteracted adipocyte enlargement. An age-dependent reduction in COX5B gene expression was also found in human visceral adipose tissue. Collectively, our findings establish a pivotal role for CIV dysfunction in progressive white adipocyte enlargement during aging, which can be restored to alleviate age-dependent WAT expansion.
