Musculoskeletal Pain, Physical Function, and Quality of Life After Bariatric Surgery

Sleeve Gastrectomy: Literature Results

Sleeve gastrectomy (SG) is the most frequently performed bariatric procedure globally. However, data regarding short- and long-term results remain insufficient. This study aimed to evaluate the short- and longterm effects of SG. We performed a thorough PubMed search for references that mentioned sleeve gastrectomy was carried out. In terms of weight loss and resolution of comorbid disorders, the immediate results have been encouraging. Although long-term results are still being obtained, a large number of individuals have experienced persistent weight loss. Eight short-term studies were extracted for the present review. Each study clarified that SG was utilized as a management technique for a high-risk patient population or as a component of a stepwise therapeutic procedure. The laparoscopic SG method was examined in all studies. The percentage of patients who were followed up for 30 days or longer after LSG was reported. Significant weight loss has been observed in studies that evaluated short-term results. An excess weight loss of 67.3% and a significant decrease in body mass index (BMI) were observed in a systematic evaluation of 5,218 patients. In long-term studies, SG was administered to 2713 patients, of whom 1626 completed the five-year follow-up period. Among all patients, 71.3% were women and 28.7% men. The mean BMI before surgery was 46.9 kg/m². The follow-up durations ranged from 5 to 11 years. The mean five-year follow-up rate was 66% (range 57-100%). At 5, 6, 7, 8 and 11 years, the mean percentage excess weight decreases were 58.4%, 59.5%, 56.6% and 62.5%, respectively. Five years after SG, resolution of type 2 diabetes resolved in 77.8% of patients, and arterial hypertension, dyslipidemia, obstructive sleep apnea, gastroesophageal reflux disease and degenerative joint diseases improved or resolved in 68.0%, 65.9%, 75.8%, 30.6% and 55.7% of patients, respectively. Laparoscopic SG is more technically straightforward and has fewer surgical complications than other more complex surgical techniques. Laparoscopic SG is an effective treatment option for bariatric surgery. It is relatively easy to perform, well tolerated by patients and effective for longterm excessive weight loss and resolution of comorbidities.

Changes in Branched-Chain Amino Acids One Year after Sleeve Gastrectomy in Youth with Obesity and Their Association with Changes in Insulin Resistance

Adults with obesity have a reduction in branched-chain amino acid (BCAA) levels following metabolic and bariatric surgery (MBS), which is hypothesized to contribute to the metabolic advantages of MBS. We examined this relationship in 62 youth 13-24 years old with severe obesity (47 female) over 12 months. Thirty had sleeve gastrectomy (SG) and 32 were non-surgical controls (NS). We measured fasting insulin, glucose, glycated hemoglobin (HbA1c), isoleucine, leucine, and valine concentrations, and post-prandial insulin and glucose, following a mixed meal tolerance test. Twenty-four-hour food recalls were collected. At baseline, groups did not differ in the intake or the serum levels of BCAAs, HbA1C, HOMA-IR, Matsuda index, insulinogenic index, or oral Disposition index (oDI). Over 12 months, SG vs. NS had greater reductions in serum BCAAs, and SG had significant reductions in BCAA intake. SG vs. NS had greater reductions in HbA1c and HOMA-IR, with increases in the Matsuda index and oDI. In SG, baseline leucine and total BCAA concentrations were negatively correlated with the baseline Matsuda index. Reductions in serum leucine were positively associated with the reductions in HOMA-IR over 12 months. These associations suggest a potential role of BCAA in regulating metabolic health. Reducing dietary intake and serum BCAA concentrations may reduce insulin resistance.

Serum Oxytocin Levels Decrease 12 Months Following Sleeve Gastrectomy and Are Associated with Decreases in Lean Mass

Oxytocin (OXT), an anorexigenic hormone, is also bone anabolic. Further, OXT administration results in increases in lean mass (LM) in adults with sarcopenic obesity. We examine, for the first time, associations of OXT with body composition and bone endpoints in 25 youth 13-25 years old with severe obesity who underwent sleeve gastrectomy (SG) and 27 non-surgical controls (NS). Forty participants were female. Subjects underwent fasting blood tests for serum OXT and DXA for areal bone mineral density (aBMD) and body composition. At baseline, SG vs. NS had higher median body mass index (BMI) but did not differ for age or OXT levels. Over 12 months, SG vs. NS had greater reductions in BMI, LM, and fat mass (FM). OXT decreased in SG vs. NS 12 months post-SG. While baseline OXT predicted a 12-month BMI change in SG, decreases in OXT levels 12 months post-SG were not associated with decreases in weight or BMI. In SG, decreases in OXT were positively associated with decreases in LM but not with decreases in FM or aBMD. Loss of LM, a strong predictor of BMD, after bariatric surgery may reduce functional and muscular capacity. OXT pathways may be targeted to prevent LM loss following SG.

Skeletal Effects of Sleeve Gastrectomy in Adolescents and Young Adults: A 2-Year Longitudinal Study

CONTEXT

Vertical sleeve gastrectomy (VSG) is an increasingly common tool to achieve weight loss and improve metabolic health in adolescents and young adults with obesity, although it may adversely affect bone health.

OBJECTIVE

This work aimed to evaluate the effect of VSG on bone health in youth.

METHODS

An observational 2-year study was conducted at a tertiary care center of 66 patients aged 13 to 24 years with moderate-to-severe obesity meeting criteria for VSG. The patients underwent VSG (n = 30) or nonsurgical (n = 36) management per the decision of patient and clinical team. Main outcome measures included dual-energy x-ray absorptiometry (DXA) and high-resolution peripheral quantitative computed tomography (HRpQCT) measures of bone mineral density (BMD), geometry, and microarchitecture.

RESULTS

VSG patients achieved 25.3 ± 2.0% weight loss at 2 years (P < .001) while control subjects gained 4.0 ± 2.0% (P = .026). Total hip BMD declined 8.5 ± 1.0% following VSG compared with 0.1 ± 1.0% gain in controls (P < .001), with similar results at the femoral neck (P < .001). Total volumetric BMD (vBMD) decreased both at the distal radius and tibia following VSG (P < .001) driven primarily by trabecular vBMD loss (P < .001). Two-year changes in cortical vBMD did not differ between groups, though cortical porosity decreased following VSG both at the radius and tibia (P = .048 and P < .001). Cortical thickness increased in controls but not in VSG (P = .022 and P = .002 for between-group comparisons at the radius and tibia, respectively). Following VSG, estimated failure load decreased at the radius and did not demonstrate the physiologic increases at the tibia observed in controls.

CONCLUSION

VSG leads to progressive changes in bone health over 2 years, and may lead to increased skeletal fragility in adolescents and young adults.

The Prevalence of Depression and Anxiety in Post-bariatric Surgery Patients at King Khalid University Hospital, Riyadh

Background Obesity negatively impacts mental and physical health and is a leading cause of disease worldwide. Obesity affects 33% of Saudi adults, with 10% being morbidly obese (body mass index, BMI >40 kg/m²). This study explored the association between bariatric surgery (BS) and a predisposition or exacerbation of depressive and anxiety symptoms. Material and methods A cross-sectional study of patients who underwent bariatric surgery at the King Khalid University Hospital in Riyadh, Saudi Arabia, was conducted between February 2016 and December 2021. The patients were contacted by phone to complete a self-administered questionnaire on demographic information, chronic medical diseases, psychiatric diseases, body mass index, and type of bariatric surgery. In addition, they completed the patient health questionnaire-9 (PHQ-9) and general anxiety disorder-7 (GAD-7) questionnaire to screen for patients' depression and anxiety symptoms. Results The findings of the 367 BS patients showed that 20.7% of the patients were considered to have mild anxiety, 11.2% had moderate anxiety, and 8.7% had high anxiety levels. However, regarding depression, 46.9% had extremely low levels of depression, followed by mild depression in 29.4% and moderate depression in 11.2%. Furthermore, another 8.2% of BS patients had moderately high depression levels, and 4.4% had severe depression. The anxiety and depression levels of the patients in this study did not show any statistically significant changes postoperatively in the short, medium, or long term. On the other hand, almost all of the patients 97% who underwent bariatric surgery were satisfied with the outcome of their surgery. Conclusion Few BS patients had high symptoms of depression and anxiety. We recommend pre- and postoperative psychiatric assessment for all bariatric surgery patients as surgical protocol.

Disparity Between United States Adolescent Class II and III Obesity Trends and Bariatric Surgery Utilization, 2015-2018

OBJECTIVES

Class II (120% > body mass index [BMI] < 140% of the 95th percentile for age and sex) and Class III (BMI >140% of the 95th percentile for age and sex) obesity are the fastest growing subcategories of obesity in the United States pediatric population. Metabolic and bariatric surgery (MBS) is a safe and effective treatment option for with class II/III obesity. The primary objectives of this analysis were to determine the (1) current US MBS utilization rates in those with class II/III obesity and (2) utilization rates and 30-day postoperative outcomes.

BACKGROUND

The 2015 to 2018 National Health and Nutrition Examination Survey cross-sectional data (N = 19,225) generated US with class II/III obesity prevalence estimates. The 2015 to 2018 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) longitudinal (30 days) cohort data were used to compare adolescent and adult (N = 748,622) postoperative outcomes and to calculate utilization rates.

METHODS

The 2015 to 2018 youth and adult MBS utilization rates were calculated using MBSAQIP data (numerator) and National Health and Nutrition Examination Survey data (denominator). Two-sample tests of proportions were performed to compare the MBS utilization rates by age, ethnicity, and sex and expressed per 1000.

RESULTS

Mean age of the analytical MBSAQIP sample was 17.9 (1.15) years in youth (n = 3846) and 45.1 (11.5) in adults (N = 744,776), majority female (77.4%, 80.7%, respectively) and non-Hispanic White (68.5%, 59.4%, respectively). The overall 2015 to 2018 MBS utilization rate for youth was 1.81 per 1000 and 5.56 per 1000 for adults ( P < 0.001). Adult patients had slightly higher percentage (4.2%) of hospital readmissions compared to youth (3.4%, P = 0.01) but there were no other post-MBS complication differences. From 2015 to 2018 the US prevalence of youth with class II/III obesity increased in Hispanics and non-Hispanic Blacks (P trend < 0.001), but among youth who did complete MBS non-Hispanic Whites had higher rates of utilization (45.8%) compared to Hispanics (22.7%) and non-Hispanic blacks 14.2% (P = 0.006).

CONCLUSIONS

MBS is an underutilized obesity treatment tool for both youth and adults, and among ethnic minority groups in particular.

Short-Term Changes in Mental, Physical, and Social Factors After Metabolic Bariatric Surgery in Adolescents: A Nationwide Prospective Cohort Study

Background

Metabolic bariatric surgery (MBS) is an effective treatment for adolescents with severe obesity. However, changes in mental, physical, and social factors, as well as their association with the extent of excess weight loss (%EWL) after MBS, remain controversial.

Methods

We followed 97 adolescents (64% females, aged 17 ± 0.9 years, BMI 46.1 ± 5.9 kg/m2) before and 9 months following MBS in a multi-center, prospective cohort study. Changes in mental, physical, and social factors were assessed by self-reported questionnaires, and associations with %EWL were evaluated after adjustment for potential confounders.

Results

The body mass index (BMI) decreased by 30%, and all physical parameters significantly improved (p ≤ 0.001). Energy level increased by 24%, mood level by 14%, and mental health by 9.5% (p ≤ 0.002). Social parameters were also improved, with a significant decrease in social rejection (p = 0.02), and an increase in participation in after-school social activities (p = 0.008). Mental health improvement was associated with baseline social rejection (r = 0.514, p < 0.001). The improvement in all factors was not related to the extent of %EWL.

Conclusion

Metabolic bariatric surgery MBS in adolescents led to a meaningful decrease in BMI and to an improvement in short-term physical, mental, and social factors that were not related to %EWL. Patients experiencing social rejection may improve their mental health following BS.

Investigation of Body Awareness and Affecting Factors in Patients with Bariatric Surgery

BACKGROUND

Major weight loss after bariatric surgery (BS) makes the body sensitive to the environment. The factors associated with body awareness are unknown in patients with BS. In this study, we aimed to investigate the body awareness and the affecting factors in patients with BS.

METHODS

Our study included 81 patients who had BS at least 6 months ago and 40 people of the same age and gender who had not. Participants' body awareness was evaluated with the Body Awareness Questionnaire, body compositions with bioelectric impedance device, joint position sensation (JPS) with photography method, physical activity level with International Physical Activity Questionnaire, quality of life with the Short Form-36, depression status with the Beck Depression Inventory, and cognition with the Montreal Cognitive Assessment Scale. Mann-Whitney U and Chi-square tests were used for the comparison of the groups, and Spearman correlation analysis was used for in-group correlation analysis.

RESULTS

Body awareness was found to be higher in patients with BS compared to the control group (p = 0.002). Body awareness had a positive correlation with cognition (r = 0.277, p = 0.012), quality of life sub-scales (r = 0.245-0.374, p < 0.05), the amount of change in total body weight (r = 0.241, p = 0.027), and body mass index (BMI) (r = 0.269, p = 0.032); negative correlation with depression (r =  - 0.409, p = 0.016) and deviation in the JPS (r =  - 0.223, p = 0.046).

CONCLUSION

Body awareness of patients with BS was found to be high after surgery. Body awareness in patients with BS is associated with the amount of weight loss and BMI, depression, cognition, JPS, and health-related quality of life.

Pain, disability, and lifestyle: Patients with complex regional pain syndrome compared to chronic musculoskeletal pain - a retrospective analysis

BACKGROUND

Complex regional pain syndrome (CRPS) is an orphan disease occurring as a complication after trauma. Due to its acute onset and the typical clinical presentation of the inflammatory and autonomous signs, it is an eye-catching chronic pain disease affecting also young and working people. In social media and the internet, high pain severity and unfavorable prognosis is often empathized.

METHODS

Here, we compared epidemiological, pain and lifestyle factors of 223 CPRS patients from the "ncRNAPain" cohort with 255 patients with chronic musculoskeletal pain (MSK). MSK patients were recruited at the beginning of a multimodal pain therapy program. We searched for factors predicting pain intensity.

RESULTS

Both chronic pain diseases affected women in middle age. Patients with MSK were more obese, drank more alcohol and were less educated (Pearson Chi-square Test or Mann-Whitney/U-Test). Both groups smoked more than healthy people in the OECD (Organization for Economic Cooperation and Development). Mann-Whitney/U-Test confirmed that CRPS patients did not have more severe pain and did not suffer more from pain-related disability than patients with MSK. CRPS patients also had less psychiatric comorbidities. Multiple linear regression analysis revealed that group assignment, depressive characteristics, body mass index, average alcohol consumption and smoking predicted higher pain ratings, while disease duration, anxiety symptoms or gender had no influence on pain intensity.

CONCLUSION

In summary our study supports a more optimistic view on pain in CRPS patients in comparison to MSK and identifies lifestyle factors which might contribute to the pathophysiology like smoking and drinking. Important next steps are the identification of CRPS patients at risk for chronification or - vice versa - with protective factors for pain resolution.

A prospective longitudinal study of chronic abdominal pain and symptoms after sleeve gastrectomy

BACKGROUND

Sleeve gastrectomy (SG) is widely applied. Few studies have evaluated patient-reported abdominal symptoms after SG.

OBJECTIVE

To evaluate the prevalence of chronic abdominal pain (CAP) and symptom characteristics after SG.

SETTING

Oslo University Hospital and Voss Hospital.

METHODS

We performed a longitudinal prospective cohort study of patients operated on with SG at two tertiary referral centers. For broad assessments of abdominal pain and symptoms, consultations were performed and questionnaires retrieved before and 2 years after SG. The definition of CAP or recurrent abdominal pain lasting for more than 3 months was sustained. Preoperative predictors of CAP were explored.

RESULTS

Of 249 patients at baseline, 207 (83.1%) had follow-up consultations. Mean preoperative body mass index was 43.9 (6.0) kg/m², and 181 patients (72.7%) were female. Total weight loss was 31.9% (10.4%). CAP was reported in 32 of 223 patients (14.3%) before and in 50 of 186 patients (26.9%) after SG (P =.002). All mean gastrointestinal symptoms rating scale questionnaire scores increased after SG, and they were higher in patients with CAP. Symptoms of depression decreased but were more prevalent in patients with CAP at follow-up. Most quality-of-life scores increased after SG. However, patients with CAP had lower scores (except for physical functioning). Preoperative bothersome Gastrointestinal Symptom Rating Scale reflux symptoms, study center, and younger age seemed to predict CAP after SG.

CONCLUSION

The prevalence of patient-reported CAP increased after SG. Patients reporting CAP had reduced quality-of-life scores.

Patient-reported Outcomes After Metabolic Surgery Versus Medical Therapy for Diabetes: Insights From the STAMPEDE Randomized Trial

OBJECTIVE

The aim of this study was to investigate the long-term effects of medical and surgical treatments of type 2 diabetes mellitus (T2DM) on patient-reported outcomes (PROs).

BACKGROUND

Robust data on PROs from randomized trials comparing medical and surgical treatments for T2DM are lacking.

METHODS

The Surgical Treatment And Medications Potentially Eradicate Diabetes Efficiently (STAMPEDE) trial showed that 5 years after randomization, Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) were superior to intensive medical therapy (IMT) alone in achieving glycemic control in patients with T2DM and obesity. A subset of 104 patients participating in the STAMPEDE trial were administered two generic health-related quality of life (QoL) questionnaires (RAND-36 and EQ-5D-3L) and a diabetes-specific instrument at baseline, and then on an annual basis up to 5 years after randomization.

RESULTS

On longitudinal analysis, RYGB and SG significantly improved the domains of physical functioning, general health perception, energy/fatigue, and diabetes-related QoL compared with IMT group. In the IMT group, none of the QoL components in the generic questionnaires improved significantly from baseline. No significant long-term differences were observed among the study groups in measures of psychological and social aspects of QoL. On multivariable analysis, independent factors associated with improved general health perception at long-term included baseline general health (P < 0.001), insulin independence at 5 years (P = 0.005), RYGB versus IMT (P = 0.005), and SG versus IMT (P = 0.034). Favorable changes following RYGB and SG were comparable.

CONCLUSIONS

In patients with T2DM, metabolic surgery is associated with long-term favorable changes in certain PROs compared with IMT, mainly on physical health and diabetes-related domains. Psychosocial well-being warrants greater attention after metabolic surgery.

Caring for US Children: Barriers to Effective Treatment in Children with the Disease of Obesity

In 2020, impediments to pediatric obesity (PO) treatment remain pervasive, even though these barriers are clearly documented in medical literature. Providers must invest considerable resources to overcome these barriers to care. Notable barriers include gaps in medical education, misperceptions of the disease, weight bias and stigma, exclusion of coverage in health plans, and thus an unsustainable financial framework. Hence, this review offers an updated social-ecological framework of accessibility to care, wherein each barrier to care or variable is interdependent on the other and each is critical to creating forward momentum. The sum of all these variables is instrumental to overall smooth function, configured as a wheel. To treat PO effectively, all variables must be adequately addressed by stakeholders throughout the health care system in order to holistically comprehend and appreciate undertakings to advance the burgeoning field of PO medicine.

Development and application of an ethical framework for pediatric metabolic and bariatric surgery evaluation

BACKGROUND

As severe obesity continues to rise among youth, metabolic and bariatric surgery (MBS) will increasingly be used as a treatment of choice for durable weight loss and improvement of obesity-related complications. MBS for youth with intellectual and developmental disabilities (IDD) and for preadolescents has raised ethical questions.

OBJECTIVES

The purpose of this article is to present the creation and application of an ethical framework that supports why MBS should be considered in pediatrics based on the principle of justice without automatic exclusions. This framework also provides a guide for how to conduct a robust, ethically grounded evaluation of pediatric patients presenting for MBS in general, and among subpopulations including youth with IDD and preadolescents.

SETTING

Academic medical center, United States.

METHODS

An ethical framework was developed and applied through a collaboration between an MBS center at a children's hospital and the institution's ethics consult service.

RESULTS

Application of the ethical framework to address 4 core ethical questions is illustrated using 2 hypothetical cases: 1 that highlights an adolescent with IDD and 1 that highlights a preadolescent.

CONCLUSIONS

We have demonstrated the application of a novel, overarching framework to conduct the ethical evaluation of youth presenting for MBS. This framework resulted from a collaboration between MBS and ethics consult teams and has the potential to be used as a prototype for other youth-focused MBS programs. Next steps include prospective data collection to test the framework and determine its validity in the target population.

A Novel Fabrication of Dose-Dependent Injectable Curcumin Biocomposite Hydrogel System Anesthetic Delivery Method for Care and Management of Musculoskeletal Pain

Chronic musculoskeletal pain has biological, psychological, and social components. In this article, we have demonstrated the easily injectable nanocomposite carrier for the treatment of chronic musculoskeletal pain. Briefly, the curcumin (Cur) loaded with lipid nanocapsules (LNCs; Cur@LNCs) using the phase invasion method. The synthesized Cur@LNCs were characterized by using scanning electron microscopy, transmittance electron microscopy, and the size of the fabricated nanoparticles confirmed by dynamic light scattering analysis. The synthesized Cur@LNC injectable hydrogel shows excellent results in vivo in the rat model. We have examined the efficiency of the chronic constriction injury in the rat model and induced the pain using thermal paw withdrawal latency. The injectable hydrogels Cur@LNCs display a remarkable reduction in pain 7 days post administrations compared to the untreated group animals. This work could establish the preclinical candidate of the neuropathic pain response in the future.

The advantages and disadvantages of sleeve gastrectomy; clinical laboratory to bedside review

Sleeve gastrectomy is a surgical technique and a leading method in metabolic surgery. Sleeve gastrectomy gained ever-increasing popularity among laparoscopic surgeons involved in bariatric surgery and has proved to be a successful method in achieving considerable weight loss in a short time. There are some disparate effects that patients may experience after sleeve gastrectomy including a reduction in BMI, weight, blood pressure, stroke, and cancer and also a significant remission in obesity-related diseases including type 2 diabetes (T2D), Non-alcoholic fatty liver (NAFLD), cardiovascular disease, obstructive sleep apnea, and craniopharyngioma-related hypothalamic obesity as well as non-obesity-related diseases such as gout, musculoskeletal problems, ovarian disorders and urinary incontinence. The most common complications of sleeve gastrectomy are bleeding, nutrient deficiencies, and leakage. There are several studies on the impact of gender and ethnic disparities on post-operative complications. This study collects state of the art of reports on sleeve gastrectomy. The aim of this study was to analyze recent studies and review the advantages and disadvantages of sleeve gastrectomy.
