Risk of wrist fracture, estimated by the load-to-strength ratio, declines following sleeve gastrectomy in adolescents and young adults. Osteoporos Int 2024; 35:285-291. [PMID: 37864596 DOI: 10.1007/s00198-023-06941-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Accepted: 10/04/2023] [Indexed: 10/23/2023]
Abstract
To understand whether the bone loss which occurs after vertical sleeve gastrectomy increases the risk of fracture, we used an engineering model to estimate risk in participants before and after surgery. We found that estimated risk decreased 1 year after surgery and remained lower, though had rebounded, at year 2. PURPOSE Vertical sleeve gastrectomy (VSG) improves metabolic health in young people with obesity but is accompanied by substantial loss of bone mass and estimated bone strength. We thus estimated fracture risk following VSG using the load-to-strength ratio (LSR), which integrates bone strength estimates with the predicted force of a fall. METHODS Prospective 2-year study of youth ages 13-24 years with obesity undergoing VSG (n = 24) or lifestyle therapy (n = 34). We performed high-resolution peripheral quantitative computed tomography of the distal radius and microfinite element analysis to estimate bone strength and calculated LSR. RESULTS VSG participants lost 26.4 ± 8.1% weight at year 1 (p < 0.001), which was sustained at year 2, while control participants gained weight at year 2 (4.5 ± 8.3%, p = 0.009). The predicted impact force decreased at years 1 and 2 following VSG (p < 0.001) but increased at year 2 among controls (p = 0.011). Estimated bone strength was unchanged at year 1 but decreased (p < 0.001) at year 2 following VSG, while bone strength did not change in controls. At year 1, the LSR decreased among VSG participants (p < 0.001), implying a lower risk of fracture. At year 2, the LSR was lower than baseline (p < 0.001), but higher compared to year 1 (p = 0.001). LSR did not change in the control group. CONCLUSIONS Short-term estimated fracture risk at the radius following VSG decreases. However, ongoing bone loss despite stable weight between years 1 and 2 leads to a concerning rise in estimated fracture risk. Longer follow-up will be critical to evaluate the trajectory of fracture risk. (ClinicalTrials.gov NCT02557438, registered 9/23/2015).

[PMID: 35927921 DOI: 10.2174/1573396318666220801093225] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/04/2022] [Revised: 04/05/2022] [Accepted: 05/19/2022] [Indexed: 11/22/2022]
Abstract
BACKGROUND Childhood obesity is an important and serious public health problem worldwide. OBJECTIVE This article aims to familiarize physicians with the evaluation, management, and prevention of childhood. METHODS A PubMed search was conducted in May, 2021, in Clinical Queries using the key terms "obesity" OR "obese". The search included clinical trials, randomized controlled trials, case-control studies, cohort studies, meta-analyses, observational studies, clinical guidelines, case reports, case series, and reviews. The search was restricted to English literature and children. The information retrieved from the above search was used in the compilation of the present article. RESULTS Most obese children have exogenous obesity characterized by a growth rate for height above the 50th percentile, normal intelligence, normal genitalia, and lack of historical or physical evidence of an endocrine abnormality or a congenital syndrome. Obese children are at risk for dyslipidemia, hypertension, diabetes mellitus, non-alcoholic fatty liver disease, obstructive sleep apnea, psychosocial disturbances, impaired quality of life, and shorter life expectancy. The multitude of serious comorbidities necessitates effective treatment modalities. Dietary modification, therapeutic exercise, and behavioral modification are the fundamentals of treatment. Pharmacotherapy and/or bariatric surgery should be considered for obese individuals who do not respond to the above measures and suffer from a serious comorbid condition. CONCLUSION Childhood obesity, once established, is often refractory to treatment. Most treatment programs lead to a brief period of weight loss, followed by rapid re-accumulation of the lost weight after the termination of therapy. As such, preventive activity is the key to solving the problem of childhood obesity. Childhood obesity can be prevented by promoting a healthy diet, regular physical activity, and lifestyle modification. Parents should be encouraged to get involved in school and community programs that improve their children's nutritional status and physical activity.

The Effect of Yoga on Early Clinical Outcomes and Pulmonary Functions in Patients Scheduled for Bariatric Surgery: a Randomized Controlled Study. Obes Surg 2024; 34:163-169. [PMID: 37897640 DOI: 10.1007/s11695-023-06925-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Revised: 10/19/2023] [Accepted: 10/20/2023] [Indexed: 10/30/2023]
Abstract
PURPOSE The present research was undertaken to investigate the effect of yoga on pulmonary function and early clinical outcomes in patients scheduled for bariatric surgery. MATERIALS AND METHODS This research with a randomized control group was performed on patients scheduled for bariatric surgery between October 2021 and June 2022 in the General Surgery Clinic of a University Hospital in Eastern Turkey. The sample consists of 100 randomized patients who received yoga breathing exercises and routine care. Pulmonary function test (PFT), posteroanterior chest X-rays (CXR), 6-min walk test, and oxygen saturation (SpO2) were applied as a pretest. The researcher practiced yoga for 40 min every day of the week. Post-test measurements were performed at the end of the yoga practice. Control group patients underwent the tests at the same intervals without any modifications to the standard clinical protocol. RESULTS The difference between the control and experimental groups was significant in terms of post-test PFT measurements (p < 0.001). In the CXR of the patients, a statistically significant improvement was determined in 61.5% of the patients with yoga breathing practice (p < 0.001). Also, there was a significant increase in the 6-min walk test and SpO2 values in the experimental group (p < 0.05). CONCLUSION Yoga practice positively affected the pulmonary function values of the patients.

Abstract
Obesity affects approximately 1 in 5 youth globally and increases the risk of complications during adolescence and young adulthood, including type 2 diabetes, dyslipidemia, hypertension, non-alcoholic fatty liver disease, obstructive sleep apnea, and polycystic ovary syndrome. Children and adolescents with obesity frequently experience weight stigma and have an impaired quality of life, which may exacerbate weight gain. Pediatric obesity is typically defined using sex-, age-, and population-specific body mass index percentiles. Once identified, pediatric obesity should always be managed with lifestyle modification. However, adolescents with obesity may also benefit from anti-obesity medications (AOM), several of which have been approved for use in adolescents by the US Food and Drug Administration, including liraglutide, phentermine/topiramate, and semaglutide. For children with specific, rare monogenic obesity disorders, setmelanotide is available and may lead to significant weight loss. Metabolic and bariatric surgery may be used for the management of severe obesity in youth; though highly effective, it is limited to specialized centers and has had relatively low pediatric uptake. In this narrative review using pediatric-focused data from original research, reviews, clinical practice guidelines, governmental agencies, and pharmaceutical companies, we review obesity-related metabolic complications in youth and management strategies, including AOM and bariatric surgery.

Abstract
Transplantation of brown adipose tissue (BAT), engineered thermogenic progenitor cells, and adipocytes have received much attention for the improvement of obesity and metabolic disorders. However, even though the thermogenic and metabolic potential exists early after transplantation, the whitening of the brown fat graft occurs with metabolic function significantly impaired. In this review, specific experiment designs, graft outcomes, and metabolic benefits for the transplantation of BAT or engineered cells will be discussed. The current advancements will offer guidance to further investigation, and the obstacles appearing in previous studies will require innovation of BAT transplantation methods.

Abstract
CONTEXT Sleeve gastrectomy (SG) improves metabolic endpoints but is associated with impaired bone outcomes. OBJECTIVE To determine mechanisms contributing to impaired bone health in youth following SG. METHODS 12-month longitudinal observational study in a multidisciplinary tertiary-care hospital, including 64 youth 13-25 years old with moderate-to-severe obesity (51 females); 30 underwent SG and 34 were nonsurgical (NS) controls. SG was undertaken after a combined decision-making process between treatment team and patient. The main outcome measures were fasting blood for enteric peptides, sex steroids, sclerostin, and bone turnover markers (N-terminal propeptide of type 1 procollagen [P1NP] and C-terminal cross-linking telopeptide [CTX]); dual-energy X-ray absorptiometry measures of areal bone mineral density (aBMD) and body composition; high resolution peripheral quantitative computed tomography; measures of volumetric BMD (vBMD); microfinite element analysis of strength estimates (distal radius and tibia). RESULTS SG had greater reductions in body mass index (BMI) z-scores, serum estrone, and the free androgen index (FAI) (P ≤ .046), and greater increases in sclerostin, P1NP, and CTX (P ≤ .010) than NS controls. Fasting ghrelin decreased in SG vs NS (P < .0001); fasting peptide YY did not change. Most changes were driven by female SG participants. Among females (the majority of study participants), after controlling for baseline age and race, reductions in total hip aBMD Z-scores were positively associated with changes in BMI, lean mass, estrone, FAI, and ghrelin, and inversely with changes in sclerostin.. Decreases in total vBMD of the radius and tibia were associated positively with decreases in BMI. Increases in CTX were associated with decreases in BMI, lean mass, and ghrelin, and increases in sclerostin. CONCLUSION Bone loss after SG in youth is associated with changes in body composition, sex steroids, sclerostin, and enteric peptides. These are potential targets for future preventative or therapeutic strategies.

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.

Ramadan Fasting Increases Socialization in Patients Who Underwent Sleeve Gastrectomy: An Observational Study. Obes Surg 2021; 31:2576-2582. [PMID: 33555450 DOI: 10.1007/s11695-021-05270-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2020] [Revised: 01/28/2021] [Accepted: 02/03/2021] [Indexed: 02/07/2023]
Abstract
PURPOSE The prevalence of obesity is increasing along with the number of sleeve gastrectomies. Patients' mental health and social life, along with their physical health, should be considered. Their cultural and religious values are an important part of treatment. Fasting is an important act of worship in all religions. Ramadan fasting is one of the five pillars of Islam. In this study, we aimed to investigate the effect of Ramadan fasting on quality of life in patients who underwent sleeve gastrectomy. MATERIALS AND METHODS Data regarding the demographic characteristics, weight, the time elapsed after surgery, and the amount of liquid and solid food consumed during fasting were collected with two surveys, one of which was carried out at the beginning and the other at the end of Ramadan. In addition, the SF-36 health survey questionnaire was administered to evaluate the impact of Ramadan fasting on patients' quality of life. RESULTS Fifty-one people participated in the first survey, but the second survey included 19 of them. While the median weight of the patients was 86.52 ± 17.78 kg before fasting, the median weight after 25 days of fasting was 83.31 ± 17.06 kg. A significant decrease was observed in weight after 25 days of fasting (p < 0.001). A comparison of the SF-36 scores for quality of life revealed a significant increase in the social functioning (p = 0.032). CONCLUSION Ramadan fasting caused significant weight loss in patients who underwent sleeve gastrectomy. Besides, it did not adversely affect the quality of life, but rather increased social functioning.
