Peña E, León-Mengíbar J, Powell TR, Caixàs A, Cardoner N, Rosa A. Telomere length in patients with obesity submitted to bariatric surgery: A systematic review. EUROPEAN EATING DISORDERS REVIEW 2021; 29:842-853. [PMID: 34545641 DOI: 10.1002/erv.2865] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2021] [Revised: 09/02/2021] [Accepted: 09/03/2021] [Indexed: 12/23/2022]
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.

[PMID: 32665112 DOI: 10.1016/j.soard.2020.05.015] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2020] [Revised: 04/16/2020] [Accepted: 05/12/2020] [Indexed: 12/31/2022]
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.

Role of the FKBP5 polymorphism rs1360780, age, sex, and type of surgery in weight loss after bariatric surgery: a follow-up study. Surg Obes Relat Dis 2019; 16:581-589. [PMID: 32005614 DOI: 10.1016/j.soard.2019.12.002] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2019] [Revised: 11/12/2019] [Accepted: 12/09/2019] [Indexed: 02/06/2023]
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 Age is often related to the increase of perioperative complications and reoperation rates. The authors aimed to determine the influence of age on outcomes of most commonly performed bariatric procedures. METHODS The retrospective study included patients qualified for primary Laparoscopic Sleeve Gastrectomy (LSG) or Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) in two academic hospitals. Patients were divided into two groups: ≥50 (21.2-26.9%) and <50 (57.6-73.1%) years old. Endpoints assessed the influence of patients' age on the perioperative and the one-year postoperative period. RESULTS Operative time was longer in the ≥50-year-old group, but only for LRYGB. There were no differences in the intraoperative adverse events, postoperative morbidity, reoperation and readmission rates between the groups. The risk of port site hernia was increased (OR: 4.23, CI: 1.49-12.06) in the ≥50-year-old group. The mean % of total weight loss 12 months after the bariatric procedure was comparable, but % of excess weight loss and % of excess body mass index loss were lower in the ≥50-year-old group (p = .033 and .032). CONCLUSIONS Bariatric surgery is safe and feasible in patients over 50 years old. The weight loss effect can be worse among patients over 50 years old; nevertheless, the treatment should be considered as effective.

Abstract
Background Laparoscopic adjustable gastric band (LAGB) has been an established bariatric procedure for the last three decades and was, for many years, the first-choice procedure for the treatment of chronic obesity. However, more recently, the popularity of the LAGB has been in sharp decline and has been replaced by other procedures such as the Roux-En-Y gastric bypass and sleeve gastrectomy. A key driver in this decline has been the high revision and early explanation rates reported in some studies. Methods This was a retrospective study of 2246 patients who underwent LAGB at a large private clinic in the UK between June 2004 and October 2014. Results 2246 patients were included in the study; 1945 (84.6%) were women. All patients were followed up for 2 years following their procedure and subsequent follow up was at the discretion of patients. Mean follow up duration was 43.7 +/− 29.3 months. Operative mortality was zero and there were no in-hospital returns to theatre. Mean preoperative weight and body mass index (BMI) were 111.2 ± 22.1 kg and 39.9 ± 6.7 kg/m2 respectively. Mean excess % BMI loss at 1-, 2-, 5- and 8-years of follow-up was 43.1 ± 25.4, 47.9 ± 31.9, 52.4 ± 41.7 and 57.1% ± 28.6 respectively. There was no significant difference in mean excess % BMI loss between those < 50 or ≥ 50 years old (p value = 0.23) or between patients with an initial BMI of < or ≥ 50 kg/m2 (p value = 0.65). Complications over nine years occurred in 130 (5.8%) patients and included: 39 (1.7%) slippage or pouch dilatation, 2 (0.04%) erosions and 76 (3.4%) problems related to the access port or LAGB tubing. The overall re-operation rate for LAGB complications was 4.2% over 9 years with a LAGB explantation rate of 1.5%. 39 LAGBs were converted to a sleeve or gastric bypass procedure, 11 of these due to complications. Conclusion This is the first study to report on LAGB outcomes from a private clinic in the UK. LAGB is a safe procedure, which delivers significant and durable weight loss with acceptable complications rates and low re-operation rate.

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
BACKGROUND Conflicting evidence exists regarding age as a predictive factor in excess weight loss after bariatric surgery. The objective of this cross-sectional study is to evaluate differences in excess BMI loss (%EBMIL) 1 year after surgery in patients older and younger than 45 years. METHODS Adult obese patients fulfilling selection criteria underwent either Roux-en-Y gastric bypass or sleeve gastrectomy and were grouped according to age < and ≥45 years with follow-up at least 1 year. Both groups were compared in terms of excess BMI loss (%EBMIL) and other clinical outcomes. Possible relationship between %EBMIL, age, surgical technique, and presence of comorbidities such as diabetes mellitus, hypertension (HT), and dyslipidemia (DL) was searched. RESULTS Three hundred thirty-seven patients (72.5 % female), 196 (50.1 %) younger than 45 years and 141 (49.9 %) with age ≥45 years. There was significant difference between age group and %EBMIL 12 months after surgery (p < 0.001), showing better results in younger patients. No differences were found in terms of gender, preoperative body mass index (BMI), surgical technique, nor presence of DL. Using multiple regression, we found significant interaction effect between age group (p < 0.001), presence of HT (p = 0.001), and %EBMIL at follow-up. CONCLUSIONS Patients younger than 45 years lose greater amount of excess BMI than older patients after bariatric surgery. This tendency might be useful as a preoperative weight loss predictor in bariatric patients.

Abstract
BACKGROUND Obesity is unanimously regarded as a global epidemic and a major contributing factor to the development of many common illnesses. Laparoscopic Adjustable Gastric Banding (LAGB) is one of the most popular surgical approaches worldwide. Yet, substantial variability in the results and significant rate of failure can be expected, and it is still debated which categories of patients are better suited to this type of bariatric procedure. The aim of this study was to build a statistical model based on both psychological and physical data to predict weight loss in obese patients treated by LAGB, and to provide a valuable instrument for the selection of patients that may benefit from this procedure. METHODOLOGY/PRINCIPAL FINDINGS The study population consisted of 172 obese women, with a mean ± SD presurgical and postsurgical Body Mass Index (BMI) of 42.5 ± 5.1 and 32.4 ± 4.8 kg/m(2), respectively. Subjects were administered the comprehensive test of psychopathology Minnesota Multiphasic Personality Inventory-2 (MMPI-2). Main goal of the study was to use presurgical data to predict individual therapeutical outcome in terms of Excess Weight Loss (EWL) after 2 years. Multiple linear regression analysis using the MMPI-2 scores, BMI and age was performed to determine the variables that best predicted the EWL. Based on the selected variables including age, and 3 psychometric scales, Artificial Neural Networks (ANNs) were employed to improve the goodness of prediction. Linear and non linear models were compared in their classification and prediction tasks: non linear model resulted to be better at data fitting (36% vs. 10% variance explained, respectively) and provided more reliable parameters for accuracy and mis-classification rates (70% and 30% vs. 66% and 34%, respectively). CONCLUSIONS/SIGNIFICANCE ANN models can be successfully applied for prediction of weight loss in obese women treated by LAGB. This approach may constitute a valuable tool for selection of the best candidates for surgery, taking advantage of an integrated multidisciplinary approach.
