Oxidative Stress in Postbariatric Patients: A Systematic Literature Review Exploring the Long-term Effects of Bariatric Surgery. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2024; 12:e5646. [PMID: 38515558 PMCID: PMC10956951 DOI: 10.1097/gox.0000000000005646] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Accepted: 01/16/2024] [Indexed: 03/23/2024]
Abstract
Background The present study investigates the impact of oxidative stress after bariatric surgery in patients with obesity. This field of study has gained great interest in recent years due to the role that oxidative stress plays in metabolic diseases. Obesity, by itself, can generate an increase in reactive oxygen and nitrogen species, intensifying cellular damage and promoting the progression of adverse metabolic conditions. In this context, bariatric surgery emerges as a candidate capable of modifying oxidative stress biomarkers, facilitating the patient's metabolic recovery. Methods A systematic review was carried out, identifying 30 studies found in databases such as PubMed, Scopus, Web of Science, and Google Scholar. It looked at the link between oxidative stress and recovery after bariatric surgery in patients. The selection of studies was based on the measurement of oxidative stress biomarkers before and after surgical intervention. Results The results reveal a significant decrease in oxidative stress biomarkers after bariatric surgery. However, a notable variability in antioxidant activity is observed between different patients, as well as a significant influence of comorbidities. Conclusions Bariatric surgery is postulated as an effective intervention in reducing oxidative stress in patients with obesity, enhancing antioxidant activity and improving patient recovery. This finding highlights the importance of considering oxidative stress management as an integral part of postoperative care, suggesting the need to implement complementary treatment strategies to optimize health outcomes.

Abstract
Children and adolescents with obesity who present for weight loss surgery are a unique subset of patients. A thorough understanding of the perioperative needs of these individuals is essential to avoid deleterious complications. This review illustrates the necessity for specialized care, including the continued need of specified drug dosing and a systematic approach in the management of the pediatric bariatric patient.

Abstract
The rise of childhood obesity is a growing concern due to its negative impact on health. Metabolic bariatric surgery (MBS) has gained popularity as an effective and adequate intervention for children and adolescent patients living with severe obesity. Nonetheless, access to MBS for this population is still limited. The objective of this paper is to conduct a comprehensive review of the latest national and international practice guidelines and improve access to MBS for children and adolescents. The paper focuses on the recommendations from the 2023 American Academy of Pediatrics (AAP) and 2022 guidelines from the American Society for Metabolic and Bariatric Surgery (ASMBS) and the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO). Recently updated guidelines from the ASMBS and IFSO aim to improve access to MBS for children and adolescents and recommend patient selection, preoperative evaluation, and postoperative care. While lifestyle changes, medication, and behavioral therapy are commonly prescribed, they often fail to achieve permanent weight loss and its maintenance. Weight-loss surgeries like sleeve gastrectomy (SG) and gastric bypass (RYGB) show promising results in managing severe obesity in adolescents. SG has become the preferred method for treating severe obesity in adolescents, surpassing RYGB. Weight stigma is also explored in this review, revealing its negative effects on individuals who are overweight and underweight. Furthermore, telehealth is identified as an increasingly valuable tool for managing pediatric obesity, as it can improve access to care, particularly for those in remote areas where physicians trained to treat childhood obesity and the shortage of bariatric surgeons experienced in treating younger adolescents and pediatricians with advanced training are major obstacles.

Abstract
BACKGROUND There are multiple preoperative risk scores for pediatric mortality. The aim of this study was to systematically describe and compare the existing studies of patient-specific multispecialty risk prediction scores for perioperative mortality in pediatric populations, with the goal of guiding clinicians on which may be most appropriate for use in the preoperative setting. METHODS We conducted a systematic literature review of published journal articles that presented the development, extension/updating, and/or validation of a risk score which predicted all-cause mortality (up to 30 days postoperatively) in pediatric patients undergoing a procedure in which anesthesia was used. Scores needed to be applicable to surgeries in more than one non-cardiac surgical specialty and had to be able to be calculated by the anesthesiologist at the time of the pre-anesthetic assessment. Two investigators independently screened studies for inclusion and assessed study quality in the domains of clinical applicability, feasibility/ease of use in the clinical setting, and risk of bias. RESULTS A total of 1,681 titles were retrieved. Of these, 10 studies met inclusion criteria: nine reported the development and validation of scores, and one was an external validation of an existing score. Seven studies used varying years of multicenter data from the National Surgical Quality Improvement Program - Pediatric Participant Use File for development and/or validation. The unadjusted rate of mortality in the studies ranged from 0.3% to 3.6%. The preoperative predictors of mortality used in score development included patient demographics, preoperative therapies, and chronic conditions, among others. All models showed good discrimination upon validation (AUC > 0.8). Most risk scores had high or unclear risks of bias. CONCLUSION There are numerous scores available for the prediction of mortality in pediatric populations, all of which exhibited good performance. However, many have high or unclear risks of bias, and most have not undergone external validation.

Abstract
BACKGROUND With the growing prevalence of severe obesity in adolescents, sleeve gastrectomy (SG), a type of metabolic bariatric surgery (MBS), is increasingly being performed at a younger age. Data regarding changes in homeostatic and hedonic appetite following SG are conflicting in adults, with some studies showing no change and others showing a decrease in appetite. Data evaluating the effect of SG on appetite during adolescence, when appetite is more plastic, are currently lacking. OBJECTIVE To evaluate appetite changes one year after SG in adolescents with obesity vs. in non-surgical controls (NS). METHODS Thirty-nine subjects 13-21 years old with severe obesity were followed for a year; 19 underwent SG, and 20 were followed without surgery. Subjects had fasting blood tests for appetite-regulating hormones and completed a visual analog scale for appetite assessment (VAS). RESULTS The SG group had a decrease in body mass index (BMI) at one-year (baseline: 48.2 ± 1.7 kg/m2; one-year follow-up: 42.6 ± 1.0 kg/m2 (p ≤ 0.0001)). No within- or between-group differences were noted in the one-year change in appetite in the SG and NS groups. After SG, fasting ghrelin decreased (p ≤ 0.0001); however, no changes were noted in peptide YY (PYY) levels. Changes in one homeostatic appetite measure following SG were inversely associated with changes in fasting PYY (r = -0.583, p = 0.011). Appetite changes were not associated with weight loss or final BMI. CONCLUSIONS There were no changes in appetite measures one-year after SG from pre-surgery levels in adolescents with obesity, and appetite changes were not associated with changes in BMI. It is important to evaluate the impact of long-term appetite changes, if any, on weight loss after SG.

Abstract
BACKGROUND Craniopharyngioma (CP), despite being a malformational tumor of low histological grade, causes considerable morbidity and mortality mostly due to hypothalamo-pituitary dysfunction that is created by tumor itself or its treatment. SUMMARY Fluid-electrolyte disturbances which range from dehydration to fluid overload and from hypernatremia to hyponatremia are frequently encountered during the acute postoperative period and should be carefully managed to avoid permanent neurological sequelae. Hypopituitarism, increased cardiovascular risk, hypothalamic damage, hypothalamic obesity, visual and neurological deficits, and impaired bone health and cognitive function are the morbidities affecting the well-being of these patients in the long term. Key Messages: Timely and optimal treatment of early postoperative and long-term complications of CP is crucial for preserving quality of life of these patients.

Update on Metabolic Bariatric Surgery for Morbidly Obese Adolescents. CHILDREN-BASEL 2021; 8:children8050372.

Abstract
Despite worldwide public attention and intense medical efforts, the prevalence of severe morbid obesity in children and adolescents is still rising. Similar to adults, excess adipose tissue triggers multiple immunological and metabolic pathways leading to serious co-morbidities such as impaired glucose tolerance or even type 2 diabetes (T2D), dyslipidemia, arterial hypertension, non-alcoholic fatty liver disease, and hyperuricemia. The management of severe childhood obesity requires a life-long multidisciplinary approach with a combination of lifestyle changes, nutrition, and medications. Standardized life-style intervention programs remain the first-line treatment for morbid obese children and adolescents, but unfortunately reveal limited long-term success. In such cases, metabolic bariatric surgery (MBS) has evolved from being a controversial issue to being included in distinct recommendations. According to the American Society for Metabolic and Bariatric Surgery (ASMBS) Pediatric Committee, indications for bariatric surgery in adolescence must follow very strict criteria. Adolescents with class II obesity (BMI > 120% of the 95th percentile) and a diagnosed co-morbidity or with class III obesity (BMI ≥ 140% of the 95th percentile) should be considered for MBS. These interventions represent high-risk operations, and adolescents should be treated in specialized, multidisciplinary high-volume obesity centers with long-term follow-up programs. The Roux-en-Y gastric bypass (RYGB) remains the gold standard of all malabsorptive procedures. Laparoscopic sleeve gastrectomy (LSG), which the authors pioneered as a stand-alone procedure in morbidly obese adolescents in 2008, has become the most commonly performed operation in morbidly obese adolescents at present. Recent literature proves that MBS is safe and effective in morbidly obese adolescents. Mid-term data have revealed significant improvement or even resolution of major co-morbidities. Thus, MBS for the treatment of morbidly obese adolescents has evolved from being a controversial issue to being included in distinct recommendations by several medical societies as a therapeutic strategy to reduce severe co-morbidities potentially causing end-organ damage in adulthood.

Abstract
Childhood obesity can lead to comorbidities that cause significant decrease in health-related quality of life and early mortality. Recognition of obesity as a disease of polygenic etiology can help deter implicit bias. Current guidelines for treating severe obesity in children recommend referral to a multidisciplinary treatment center that offers metabolic and bariatric surgery at any age when a child develops a body mass index that is greater than 120% of the 95th percentile. Obesity medications and lifestyle counseling about diet and exercise are not adequate treatment for severe childhood obesity. Early referral can significantly improve quality and quantity of life.
