Metabolic and bariatric surgery for adolescents with severe obesity: Benefits, risks, and specific considerations

International and national guidelines recommend metabolic and bariatric surgery (MBS) as a treatment option for adolescents with severe obesity, but few countries offer MBS to adolescents in routine clinical care. This narrative review summarizes existing adolescent MBS guidelines and the available underpinning evidence. Two randomized trials and additional prospective studies have demonstrated efficacy and safety in adolescent MBS, and the health benefits appear to be similar or superior to outcomes in adults. However, there are specific challenges regarding the intervention during adolescence related to decision-making capacity and a peak in risk-taking behavior. Adolescents with severe obesity have—as a group—a mental health vulnerability, and specific nutritional concerns need to be addressed in relation to MBS. This review also describes how study findings can be translated into clinical care. We use Sweden as an example, where the National Board of Health and Welfare recommends MBS for selected adolescents with severe obesity aged 15 years or older. We present practical advice for implementing and integrating MBS in adolescents in the framework of multidisciplinary pediatric and adolescent care for obesity.

Obesity, Metabolic Syndrome, and Obesity Paradox in Heart Failure: A Critical Evaluation.

Since the turn of the millennium, obesity has been on the rise worldwide, and particularly so throughout the United States. Even more concerning is the rate at which persons with severe obesity continue to trend upwards. Given the detrimental effects of obesity on cardiac structure and function, it is not surprising that obesity stands as one of the leading risk factors for developing heart failure (HF). This state-of-the-art article aims to review the updated literature on the obesity paradox to help further understand its relationship to body composition, weight loss, fitness, and exercise. An intriguing phenomenon appears to exist in which obesity is associated with a better prognosis in those with HF, compared to patients with lesser body mass. Recent studies suggest, however, that weight loss induced by pharmacologic strategies might be beneficial in patients with HF with preserved ejection fraction. Despite the presence of an obesity paradox, recent data suggest that obesity could be targeted in HF, however, long-term data are currently lacking. Consequently, definitive guidelines for managing obesity, and specifically the body composition of these patients, remain amiss.

High Rates of Obesity and Chronic Diseases Among North Carolina United Methodist Clergy: An Updated Analysis

Background Varied demands and stressors experienced by clergy can contribute adversely to their overall well-being. Data from United Methodist Church (UMC) clergy in North Carolina in 2008 revealed that clergy had significantly higher non-communicable disease (NCD) rates than their fellow North Carolinians. Methods Using data from the Clergy Health Initiative and Behavioral Risk Factor Surveillance Survey, the present study provided an updated analysis of obesity and 6 other NCDs among North Carolina UMC clergy compared to the general North Carolina population. First, we described the prevalence of each health condition among North Carolina UMC clergy and the general North Carolina population across multiple waves from 2008 to 2021. Then, we compared the predicted probabilities of each health condition in 2021 using logistic regressions to adjust for age, sex, and race. Results Comparing the unadjusted prevalence of health conditions between 2008 and 2021, we found that North Carolina UMC clergy have higher rates of obesity, hypertension, hypercholesterolemia, diabetes, angina, arthritis, and asthma than North Carolinians overall. Adjusting for age, sex, and race, we found that significantly higher rates of obesity, severe obesity, hypercholesterolemia, and asthma persisted among UMC clergy in 2021 compared to all North Carolinians, with the higher rates of severe obesity being particularly concerning. Limitations While the current study is limited to an update of health prevalence among UMC clergy, pastors across denominations are influential leaders in their communities, shaping the physical and social health environments of their congregations. Conclusions Further research is needed to investigate risk factors, such as relocation and adverse childhood experiences, which may influence the higher prevalence of NCDs within and potentially beyond the UMC.

BS SO04 - Intragastric Balloons - are they for the long term?

Abstract Background Intragastric balloons are a bridging therapy to bariatric metabolic surgery. When sufficient weight loss to facilitate surgery is not achieved, a second balloon may be considered. Traditionally, balloons were used for 6 months prior to removal. The COVID-19 pandemic limited patient interactions and treatment duration was doubled. We assessed outcomes (weight loss trends and safety) in patients with severe obesity undergoing sequential balloon treatment. The study period accounts for changes in balloon protocol instigated during the pandemic, addressing a current literature gap. Method Consecutive patients who underwent balloon treatment between May 2014 and February 2023 were identified. Only patients deemed fit enough for potential adjuvant bariatric surgery at presentation were included in the study. Outcomes recorded included: weight and BMI at 3-monthly intervals until balloon removal, progression to surgery and morbidity. Results 45 patients were identified. Median BMI on balloon insertion was 62kg/m2. Median weight loss with the first balloon was 15.2kg (8.8% weight loss). 11 patients (24.4%) had a second balloon, with median weight loss of 3.3kg (1.9%). 22 patients (48.8%) met criteria for surgery, only one had multiple balloons. Weight loss was observed during the first three quartiles of balloon treatment, however median 2kg was gained during months 9-12. 16 (35.6%) first balloon patients had complications. 2 (18.2%) second balloon patients had complications. Median time from insertion to complication was 14 days. Conclusion The present study concludes that, although not associated with increased complication risk, sequential IGB use as a bridging treatment to definitive bariatric surgery does not significantly contribute to weight loss in super obese patients. Optimal treatment is achieved with a single IGB, although weight loss is not uniform across a 12 month treatment period and weight gain can result after 9 months.

Abstract 4115846: Early Right and Left Ventricular Echocardiographic Parameters Improvement in Obese Patients After Bariatric Surgery.

Background: Severe obesity causes hemodynamic changes in the circulatory system, which leads to the development of heart failure with either preserved or reduced ejection fraction. Weight loss achieved through bariatric surgery is likely to possibly reverse many of hemodynamic and structural abnormalities caused by obesity. Hypothesis: Right and left ventricular parameters of heart failure and function improve as soon as 3 months after surgery. Methods: Detailed echocardiographic parameters assessing left and right ventricular function in severely obese patients undergoing bariatric surgery were analyzed. The following parameters of left and right ventricular function were compared in the examinations performed before, 3 and 6 months after surgery: left ventricular ejection fraction (LVEF), LV and RV global longitudinal strain (GLS), peak early (e’) and late (a’) diastolic annular velocities (lateral and septal) with calculation of E/e’ ratios, left atrium volume index ( LAVI), TRV (tricuspid regurgitation velocity), tricuspid annular plane systolic excursion (TAPSE), maximum systolic velocity of the lateral part of the tricuspid annulus-s’ and accelerated pulmonary time (AcT). Results: Forty obese patients (76% women) with mean BMI 40.3 (SD 5.6) and mean age of 42.4 (SD 11.9) years were enrolled. BMI as 6 months was 31.2 (SD 5.1). Baseline and follow-up results of echocardiography are presented for both left and right ventricular parameters in Table 1 and Table 2. Conclusions: Only GLS for right and left ventricle, FWS and TRV improve siginicantly within 6 months from bariatric surgery. On the other hand, these changes are significant as early as 3 months after bariatric surgery.

Abstract 4137570: Atherosclerotic Cardiovascular Disease Risks in Children: An electronic health record data analytics approach

Background and Aims: There is little data on atherosclerotic cardiovascular disease (ASCVD) risk conditions, factors, and tiers in the pediatric population. This study aimed to develop and validate electronic health record (EHR) data analytic algorithms to attain the prevalence of 24 risk conditions, 7 factors, and 4 tiers in children in a rural community. Methods: This study included all the 495,902 subjects from 0 to 18 years at the Geisinger Medical Center from 2004 to 2022. The demographic and clinical data were collected using ICD-10 codes, clinical and laboratory data, and a dual-coded computational algorithm was developed based on the AHA guideline to derive the ASCVD risk conditions, factors, and tiers. To validate the EHR algorithms, the algorithm (rater 1) and a clinician (rater 2) extracted and analyzed the data from 40 randomly selected subjects from this cohort. Kendall’s coefficient of concordance (W) and Gwet’s agreement coefficient were used to evaluate algorithm and clinician agreement within the ASCVD tiers, conditions and factors, respectively. Results: High concordance was observed between algorithmic and clinician raters for risk tiers (W=80%), conditions (80-97%), and factors (49% for blood pressure, and 92% to 97% for the rest of the risk factors). In this cohort, the median age was 3.9 years, 51.0% were male, 80.6% were Non-Hispanic/Latino, and 88.1% were White. Overall, 15.5% (N = 76,945) were at-risk, 7.0% (N = 34,530) at moderate risk, and 4.2% (N = 20,761) at high risk for ASCVD, respectively. The most prevalent risk conditions were obesity (9.1%, N = 45,074), chronic inflammatory conditions (6.8%, N = 33,685), severe obesity (2.7%, N = 13,442), insulin resistance with comorbidities (2.7%, N = 13,397), and hypertension (2.1%, N = 10,436). The most prevalent risk factors were elevated BMI (27.4%, N = 135,904), blood pressure (12.5%, N = 62,015), and fasting lipid profile (8.7%, N = 43,100). Conclusion: Our EHR data analytics algorithm is in high agreement with the clinician rater. The high, moderate, and at-risk ASCVD risk tiers are prevalent in a large contemporary pediatric cohort at Geisinger. Both ASCVD risk conditions and factors are also prevalent, especially obesity, diabetes, hypertension, and hyperlipidemia. These findings suggest the further application and refinement of these algorithms to design innovative approaches for ASCVD risk reduction and prevention in children.

MECHANISMS OF ACTION OF PROTEIN SHAKES IN NORMALIZING METABOLIC PROCESSES, THEIR ROLE IN IMPROVING GLYCEMIC CONTROL IN PATIENTS WITH TYPE 2 DIABETES, AND IN PREVENTING CARDIOVASCULAR DISEASES

This review article delves into the significance of protein shakes, particularly whey protein, in various health and fitness contexts. The primary focus is on their biochemical properties, metabolic benefits, and their role in supporting muscle mass, weight loss, and metabolic health. The article synthesizes findings from multiple studies to highlight the potential of protein shakes in improving glycemic control, reducing inflammation, and enhancing overall health, particularly for individuals with type 2 diabetes, obesity, and sarcopenia. The review also explores the effectiveness of protein shakes in athletic performance and recovery, as well as their impact on glucose metabolism and homeostasis. It underscores the necessity for further research to optimize the use and dosage of protein shakes for diverse populations to fully harness their benefits. Whey proteins are rich in essential amino acids, particularly leucine, which stimulates muscle protein synthesis via the mTOR pathway. This makes them highly effective in muscle building and recovery. Whey protein consumption enhances glycemic control by increasing insulin secretion and improving insulin sensitivity. Studies have shown significant reductions in fasting glucose levels and HbA1c in patients with type 2 diabetes. Protein shakes aid in weight loss by promoting satiety and increasing thermogenesis. They help maintain muscle mass during weight loss, which is crucial for sustaining metabolic rate. Clinical trials have demonstrated their efficacy in reducing body fat and improving metabolic markers. Whey protein, combined with resistance training, significantly improves muscle mass and strength in older adults, helping to prevent sarcopenia. This is essential for maintaining physical functionality and reducing the risk of falls and fractures. In the rehabilitation of patients with severe obesity, protein shakes are effective in reducing body weight, improving metabolic health, and maintaining muscle mass. They play a crucial role in comprehensive rehabilitation programs that include diet and physical exercise. Protein shakes support metabolic adaptations by preserving muscle mass and enhancing thermogenesis, which helps maintain a high metabolic rate and prevent weight regain. Whey proteins enhance muscle mass and strength, speed up recovery after training, and boost endurance. They also support the immune system and reduce oxidative stress, contributing to better overall athletic performance . Proteins shakes aid in regulating blood glucose levels and improving insulin sensitivity, which is crucial for preventing and managing diabetes. Their antioxidant and anti-inflammatory properties further enhance metabolic health.

Weight loss in patients with severe obesity after bariatric surgery-the potential role of the chrono-nutrition, chronotype and the circadian misalignment: A study protocol of the ChronoWise prospective cohort.

Despite the potential effectiveness of bariatric surgery in promoting weight loss, a considerable proportion of patients still face the challenge of achieving optimal post-surgery outcomes. The timing of eating, in addition to the content of what is eaten, as well as chronotype and social jetlag (a marker of circadian misalignment), have been implicated in weight regulation. However, the current understanding of these chrono-related behaviours in individuals undergoing bariatric surgery is still scarce. Thus, this study aims to evaluate the role of chrono-nutrition, chronotype, and circadian misalignment in the weight-loss trajectory among individuals living with severe obesity who underwent bariatric surgery. The ChronoWise project is a prospective single-centre cohort study designed to follow patients experiencing bariatric surgery at the Santo António Local Health Unit (ULSSA), Porto, Portugal. Participants will be recruited and evaluated at pre-surgery and followed-up over 3 and 6 months after surgery. The baseline evaluation will be conducted face-to-face during the hospital stay and by telephone or video call on the subsequent evaluations, following standard procedures. Data collection includes sociodemographics, food intake, chrono-nutrition behaviours, sleep time behaviour, sleep quality, screen time, physical activity and exercise behaviours, anthropometric measurements, and biochemical parameters. The 'Munich Chronotype Questionnaire' will be used to assess chronotype and social jet lag. Chrono-nutrition dimensions will be measured by the 'Chrononutrition Profile-Questionnaire' in all evaluations. Weight and height will be self-reported and retrieved from medical registries. trajectories of weight-loss will be obtained. This study will add important evidence on the role of chrono-nutrition, chronotype and social jetlag profile in weight-loss outcomes after bariatric surgery. Identifying novel approaches to change the paradigm of post-surgical weight management towards a tailored treatment aligned with circadian rhythm may be useful to strengthen the existing treatments and improve patients' response to bariatric surgery.

Higher BMI Is Associated With Wound Breakdown Following Resection of Haglund Deformity.

Haglund deformity is characterized by an enlarged posterosuperior calcaneus, often with inflammation of the retrocalcaneal bursa and Achilles tendon. This study aims to determine if obesity is associated with an increased rate of complications after Haglund resection. A retrospective review was conducted on patients who underwent surgical resection for Haglund deformity from January 2015 to December 2023 at a single academic center. The patient cohort was initially stratified by body mass index (BMI) into normal (BMI < 25), overweight (25 ≤ BMI < 30), and obese (BMI ≥ 30). For those classified as obese, further subclassification was performed using the standard system: obesity class I (mild obesity) = BMI 30.0-34.9; obesity class II (moderate obesity) = BMI 35.0-39.9; and obesity class III (severe obesity) = BMI ≥40.0. Data on demographics, surgical techniques, and weightbearing were collected and analyzed. Postoperative complications were compared between groups. Of the 370 patients included in this study, 20 (5.4%) were classified as normal, 77 (20.8%) were overweight, and 273 (73.8%) were obese. Within the cohort of patients with obesity, 96 (35.2%) were classified as obesity class I, 96 (35.2%) as obesity class II, and 81 (29.7%) as obesity class III.The obese group had a higher proportion of females (70.0%) and Black/African American race (24.5%), and a higher prevalence of diabetes mellitus (22.0%) and American Society of Anesthesiologists scores compared with other groups. Additionally, analysis within the obesity subclassifications revealed significant differences in smoking status, with a higher proportion of nonsmokers as obesity class increased (58.3% in class I, 76.0% in class II, and 79.0% in class III; P = .01). Follow-up duration averaged 10.5 months, with wound breakdown rates significantly higher in the obese group vs the overweight or normal groups (11.0% vs 2.6% vs 0.0%, P = .02). No significant differences in wound complications or outcomes were observed between patients based on different obesity subclassifications. Our findings demonstrate that after Haglund resection, obese patients have a higher risk of complications, particularly wound breakdown. This underscores the necessity of careful patient selection and perioperative optimization.

Nutritional status of Saudi obese patients undergoing laparoscopic sleeve gastrectomy, one-year follow-up study.

Bariatric surgery has significantly increased globally as an effective treatment for severe obesity. Nutritional deficits are common among candidates for bariatric surgery, and follow-up of nutritional status is critically needed for post-surgery healthcare management. This observational prospective study was conducted at King Khalid University Hospital in Riyadh. Samples were collected pre- and post-laparoscopic sleeve gastrectomy (LSG), with the visit intervals divided into four visits: pre-surgery (0M), 3 months (3M), 6 months (6M) and 12 months (12M). Food intake and eating patterns significantly changed during the first year (P < 0·001). The mean energy intake at 3M post-surgery was 738·3 kcal, significantly lower than the pre-surgery energy intake of 2059 kcal. Then, it increased gradually at 6M and 12M to reach 1069 kcal (P < 0·00). The intake of Fe, vitamin B12 and vitamin D was below the dietary reference intake recommendations, as indicated by the 24-hour dietary recall. The prevalence of 25 (OH) vitamin D deficiency improved significantly from pre- to post-surgery (P < 0·001). Vitamin B12 deficiency was less reported pre-LSG and improved steadily towards a sufficient post-surgery status. However, 35·7 % of participants were deficient in Fe status, with 28·6% being female at higher levels than males. While protein supplementation decreased significantly over the 12M follow-up, the use of vitamin supplements dramatically increased at 3 and 6M before declining at 12M. Fe and vitamin B12 were the most popular supplements after vitamin D. This study confirms the necessity for individualised dietary plans and close monitoring of candidates' nutritional status before and after bariatric surgery.

Genetic and functional analyses of CTBP2 in anorexia nervosa and body weight regulation.

The C-terminal binding protein 2 (CTBP2) gene (translational isoforms: CTBP2-L/S, RIBEYE) had been identified by a cross-trait analysis of genome-wide association studies for anorexia nervosa (AN) and body mass index (BMI). Here, we did a mutation analysis in CTBP2 by performing polymerase chain reactions with subsequent Sanger-sequencing to identify variants relevant for AN and body weight regulation and ensued functional studies. Analysis of the coding regions of CTBP2 in 462 female patients with AN(acute or recovered), 490 children and adolescents with severe obesity, 445 healthy-lean adult individuals and 168 healthy adult individuals with normal body weight detected 24 variants located in the specific exon of RIBEYE.In the initial analysis, three of these were rare non-synonymous variants (NSVs) detected heterozygously in patients with AN (p.Arg72Trp - rs146900874; p.Val289Met -rs375685611 and p.Gly362Arg - rs202010294). Four NSVs and one heterozygousframeshift variant were exclusively detected in children and adolescents with severe obesity (p.Pro53Ser - rs150867595; p.Gln175ArgfsTer45 - rs141864737; p.Leu310Val - rs769811964; p.Pro397Ala - rs76134089 and p.Pro402Ser - rs113477585). Ribeye mRNA was detected in mouse hypothalamus. No effect of fasting or overfeeding on murine hypothalamic Ribeye expression was determined. Yet, increased Ribeye expression was detected in hypothalami of leptin-treated Lepob/ob mice. This increase was not related to reduced food intake and leptin-induced weight loss. We detected rare and frequent variants in the RIBEYE specific exon in both patients with AN and in children and adolescents with severe obesity. Our data suggest RIBEYE as a relevant gene for weight regulation.

Association of High-Sensitivity C-Reactive Protein (hs-CRP) with Weight Loss After Sleeve Gastrectomy and Roux-en-Y Gastric Bypass at 10 Years: A Secondary Analysis of the SLEEVEPASS Randomized Clinical Trial.

Severe obesity is associated with a low-grade chronic inflammation, and high-sensitivity C-reactive protein (hs-CRP) is a marker that can be used to evaluate chronic inflammation status. Metabolic bariatric surgery (MBS) is shown to decrease hs-CRP level, but long-term results are scarce, and association with weight loss outcomes is undetermined. This study aims to evaluate chronic inflammation in patients with obesity using hs-CRP, and its association with long-term weight loss outcomes after laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB). The long-term follow-up data of SLEEVEPASS (ClinicalTrials.gov NCT00793143) randomized clinical trial (RCT) was used. Hs-CRP was measured at baseline, and at 6months, 1, 3, 5, 7, and 10years after surgery, and the association with weight and weight loss outcomes were analyzed. Hs-CRP at baseline was available for 59 out of 240 (24.6%) patients. In the whole study population, the nadir hs-CRP (mean estimate 1.14mg/ml, 95% CI 0.87-1.49) was achieved at 3years after surgery with a statistically significant difference to baseline (p = 0.003). No statistically significant difference was seen between LSG and LRYGB in hs-CRP change over time (operation*time interaction p = 0.540). Higher hs-CRP correlated with higher BMI at baseline (Spearman correlation 0.282, p = 0.030) and at 10years (Spearman correlation 0.490, p = 0.001). At 10years, a greater percentage total weight loss (%TWL) correlated with lower hs-CRP level (Spearman correlation - 0.558, p < 0.001). Baseline hs-CRP (Spearman correlation - 0.152, p = 0.299) and hs-CRP change in first 6months postoperatively (Spearman correlation 0.167, p = 0.254) did not correlate statistically significantly with %TWL at 10years. MBS decreases hs-CRP also at long-term follow-up with weight loss as the driving force. Neither baseline hs-CRP nor hs-CRP change at 6months were feasible as a predictive marker for long-term outcomes.

Bariatric Surgery in Adolescent Age Group

Obesity in children is a problematic condition which interfere with physical and mental health. It is a complicated disorder with interwoven environmental, genetic, biological components, developmental, and behavioral. A combination of medical treatment and behavioral and lifestyle modifications was typically what causes poor short-term weight loss and long-term failure. For this reason, adolescents who suffer from moderate to severe obesity and have attempted lifestyle interventions in the past but had no success should think about having bariatric surgery. Specifically, laparoscopic sleeve gastrectomy is thought to be the most often carried out bariatric procedure globally. The technique is safe and doable. It has been demonstrated that this surgical weight loss procedure is effective in young patients. However, there are obstacles that need to be removed at the levels of patients, providers, and the healthcare system. Above all, for ensuring successful long-term treatment and permit healthy growth, more should be done to stop the nutritional status decline that frequently follows bariatric surgery, as well as to prevent insufficient weight loss and weight regain. With a focus on LSG, nutritional management, and the resolution of metabolic comorbidities, we examined the clinical indications, surgical treatment options, and outcomes in adolescents with severe obesity in this narrative review.

Who Gets a Code for Obesity? Reliability, Use, and Implications of Combining International Classification of Diseases-Based Obesity Codes, 2014-2021.

Background: Many studies rely on the International Classification of Diseases, 9th or 10th Revision, Clinical Modification codes to define obesity in electronic health records data. While prior studies found misclassification and low sensitivity of codes for pediatric obesity, it remains unclear whether this misclassification is random and what are the implications of combining different code types to define obesity. Methods: We assessed prevalence, sensitivity, and specificity of obesity codes among 7.4 million children aged 2-19 years over 2014-2021. Among those with obesity in 2021, we estimated the probability of receiving any code or a specific code type by patient characteristics. Results: Obesity code utilization increased in prevalence from 3.9% in 2014 to 9.8% in 2021; prevalence of obesity based on BMI increased from 17.4% to 20.5%. Code sensitivity increased from 19.8% to 40.8%. Among children with obesity in 2021, those with severe obesity (reference: no severe obesity) and chronic disease (reference: no chronic disease) were more likely to get a code, and the highest likelihood was associated with obesity diagnosis codes (vs. status codes). Conclusions: Despite increases, obesity code utilization remained low. Obesity code misclassification is not random and certain child characteristics (e.g., severe obesity or chronic disease) are associated with a higher probability of getting a code. There are also significant differences by code type; thus, caution should be taken before combining obesity codes as a proxy for obesity status, especially in longitudinal analyses. More universal documentation of obesity may improve the quality of care and the use of these data for evaluation and research purposes.

Long-Term Outcomes of Sleeve Gastrectomy Versus Gastric Bypass.

Extremely obese patients can benefit greatly from bariatric surgery, a common and successful therapeutic procedure for treating obesity and accompanying medical issues. Although sleeve gastrectomy and gastric bypass have already demonstrated their effectiveness in this demographic, long-term results were not stated in the literature. The purpose of this research is to examine the long-term outcomes of sleeve gastrointestinal surgery and gastric bypass. This retrospective, single-center study compares 100 patients aged 25 years and older who visited the gastrointestinal tract surgical unit at Dar El-Fouad Hospital in Cairo, Egypt, between January 1 and August 31, 2019, according to the inclusion and exclusion criteria. The patients underwent either a Roux-en-Y gastric bypass (RYGB-50%) or sleeve gastrectomy (SG-50%) for severe obesity. Follow-up occurred at one year and up to four years following surgery to collect information from the study subjects. Two tools were used to assess BMI, weight loss, complications after surgery, and incidence outcome of comorbidities after the two surgeries. Qualitative data were presented as number and percentage and frequency distribution tables, and every analysis was done at a significance value < 0.05. The average age of patients within the SG group was 43.02 ± 9.19 years, whereas the average age of patients within the RYGB group was 41.02 ± 11.06 years. In addition, 74% of patients were women in both procedures. The BMI mean of the SG group was 43.90 ± 5.78, the BMI mean of the RYGB group was 42.73 ± 5.12, and the main comorbidity in both techniques was joint pain. The mean BMI at one year was 29.70 kg/m2 after SG compared with 28.64 kg/m2 after RYGB. After four years, BMI was regained within the obese range in both techniques - 30.67 kg/m2 and 30.32, respectively. Fewer postoperative complications occurred in SG than in RYGB. RYGB was superior to SG in managing dyslipidemia (DL), hypertension (HT), type 2 diabetes (T2DM), joint pain, and gastroesophageal reflux disease (GERD). There are no significant differences between the SG and RYGB in long-term outcomes regarding BMI before surgery and at follow-up, after four years, while there were statistically significant differences between them after four years than one year after surgery, and both groups showed a significant decrease in weight. However, RYGB shows improvement to some extent in comorbidities within follow-up period, including BMI, T2DM, HT, DL, HT, DL, GERD, and joint pain than SG, but with a higher rate of minor complications, while greater resolution of OSAS occurred in SG. Finally, at four years, there were no discernible variations in BMI between SG and RYGB because the patients' mean BMI was within the obese range once more.

Investigating the Prevalence of Malnutrition and Its Relationship with the Educational Status of Elementary School Students in Zahedan, Iran

Background: Malnutrition and improper nutrition may lead to physical and mental growth disorder and cognitive function. This study aims to determine the prevalence of malnutrition and its relationship with educational status among primary school children in Zahedan, Iran. Methods: During a cross-sectional study with a multi-stage random sampling method of 780 boy and girl students, first, second, and third grades of elementary school were included to study. Demographic and anthropometric of students were collected based on the sample size. Malnutrition was assessed according to World Health Organization indicators for the relevant age group. This assessment was based on body mass index (BMI) for age, height for age, and weight for age. Results: The prevalence of malnutrition was severe wasting, wasting, overweight, and obesity which were 0.8, 4.6, 6.4, and 5%, and severe underweight and underweight which were 0.9 and 4.7%, respectively. Severe stunting and stunting were observed in 0.3 and 2.8%, respectively. A statistically significant relationship was found between BMI for age, height for age and weight for age and educational status (P&lt;0.05). Moreover, the educational status of students showed a statistically significant relationship with first and second-grade gender, birth rank, and Parent’s job and education (P&lt;0.0001). Conclusion: Different forms of malnutrition among the students can negatively affect their performance, especially their educational status. Therefore, proper nutrition and increasing nutritional knowledge of primary school children and parents may help to prevent the problem.

Dental team barriers and enablers for the dental management of adults with severe obesity: a qualitative analysis

BackgroundBroad challenges regarding the dental management of people with severe obesity experienced by general dentists have been minimally explored. The perspectives of the dental team regarding these multifaceted issues are currently unknown and they potentially impede the delivery of optimal dental care to this population and contribute to poor oral and general health.AimsOur qualitative study aimed to identify and explore barriers and enablers in the dental management of adults with severe obesity among dental professionals and support staff in Australia.MethodsFocus groups and semi-structured interviews (n = 34 participants) were conducted with dental professionals (n = 23) and support staff (n = 11). Recordings were transcribed verbatim and synthesised using thematic, inductive analysis.ResultsMultiple barriers to adequate provision of dental care for people living with severe obesity in both general and specialist dental settings were identified. Key themes emerged related to the clinical challenges reported by participants in providing dental management for people living with severe obesity, appropriateness of existing bariatric dental service provision and safety of care. Enablers to access were identified, including increased availability of bariatric dental chairs, environmental modifications, education of both patients and the entire dental team and for guideline development.ConclusionThe current study explored multiple barriers to optimal dental management of people living with severe obesity in both general and specialist dental settings. Enablers should be used to inform future practice. The optimisation of existing bariatric dental service provision requires urgent review with solutions guided by systemic change. Study findings suggest a review of current health systems, economics, access barriers, policies and procedures and education and training beyond the individual level are needed. Future directions to improve the dental management of people living with severe obesity are proposed.

Blood-based MASH diagnostic in candidates for bariatric surgery using mid-infrared spectroscopy: a European multicenter prospective study

Metabolic dysfunction-associated steatotic liver disease (MASLD) is common in individuals with obesity. Sexual dimorphism is present in MASLD. A noninvasive test to diagnose the severity of the disease, in particular the presence of Metabolic dysfunction-associated steatohepatitis (MASH), is lacking. This European multicenter prospective study uses a blood test based on mid-infrared (MIR) metabolic fingerprinting of individuals with severe or morbid obesity to diagnose MASH. Three hundred eighty-two individuals with severe or morbid obesity undergoing bariatric surgery were enrolled prospectively. Liver biopsies were obtained during surgery and assessed centrally. An algorithm was defined to calculate a score from the recorded MIR spectrum and to establish a diagnostic threshold to classify patients with MASH. Among the women (n = 217), MASH was diagnosed in 14.3% of cases. For women, the performance in terms of AUC were 0.83 and 0.82 in the calibration and validation groups, respectively. For a threshold of 0.1817, sensitivities were 86% and 70%, specificities were 81% and 75%, PPV were 43% and 32%, NPV were 97% and 94% and ACC were 82% and 74% for the calibration and validation groups, respectively. For men (n = 78; MASH: 33.3%), the performance of the spectral model was poor. The metabolic fingerprint obtained by MIR spectroscopy can rule out MASH in women with severe or morbid obesity. Its value in men needs new studies.Trial registration: ClinicalTrials.gov identifier: ClinicalTrials.gov identifier: NCT03978247 (04/06/2019)
