RESUMEN

The field of endoscopic bariatric and metabolic therapy has rapidly evolved from offering endoscopic treatment of weight regain following bariatric surgery to providing primary weight loss options as alternatives to pharmacologic and surgical interventions. Gastric devices and remodeling procedures were initially designed to work through a mechanism of volume restriction, leading to earlier satiety and reduced caloric intake. As the field continues to grow, small bowel interventions are evolving that may have some effect on weight loss but focus on the treatment of obesity-related comorbidities. Future implementation of combination therapy that utilizes both gastric and small bowel interventions offers an exciting option to further augment weight loss and alleviate metabolic disease. This review considers gastric devices and techniques including space-occupying intragastric balloons, aspiration therapy, endoscopic tissue suturing, and plication interventions, followed by a review of small bowel interventions including endoluminal bypass liners, duodenal mucosal resurfacing, and endoscopically delivered devices to create incisionless anastomoses.

RESUMEN

Overweight and obesity have emerged as global health issues among children and adolescents. Restrictions related to the COVID-19 pandemic have aggravated the threat of paediatric obesity due to the prevalent reduction in physical activity (PA) in children and adolescents. However, this has also created an opportunity for healthcare professionals to explore new strategies to address this persistent problem. A systematically conducted scoping review was performed on 15 online databases to summarise and analyse the design, efficacy, and feasibility of PA-based weight management interventions for children and adolescents during the pandemic. Finally, we reviewed 23 eligible studies that were published between 2021 and 2023. The included interventions were presented to 1938 children and adolescents and 355 parents using a virtual or virtually blended face-to-face approach during the pandemic. The intervention design included a basic PA programme with three optional components (nutritional education, sociopsychological counselling, and medication consultations). Implementation generally resulted in favourable changes in body mass index (BMI) and/or body size or composition (primary outcomes), as well as health behaviours, physical health or fitness, and individual well-being (secondary outcomes). A longer duration of exposure to the intervention, female sex, and older age were associated with a higher efficacy of the included interventions. Moreover, the interventions showed high feasibility, with medium-high participant attendance, high acceptance/satisfaction in both children and adolescents and their parents and teachers, and strong participant engagement. This may be related to the high accessibility of health information, timely social support, and enhanced self-efficacy. In conclusion, both the virtual and blended delivery of well-planned weight management interventions during the pandemic show promise for the treatment and control of paediatric obesity. The lessons learned from the pandemic may help improve the design of future interventions and inform the proper integration of new technologies that have emerged in the post-pandemic world.

RESUMEN

BACKGROUND: The challenge of addressing obesity persists in healthcare, necessitating nuanced approaches and personalized strategies. This study aims to evaluate the effects of diverse therapeutic interventions on anthropometric and biochemical parameters in individuals with overweight and obesity within a real-world clinical context. METHODS: A retrospective analysis was conducted on 192 patients (141 females, 51 males) aged 18 to 75, with a BMI ranging from 25 to 30 (14.1%) and BMI ≥ 30 (85.9%), observed over a 12-month period at our Endocrinology Unit. Treatment cohorts comprised individuals following different regimens: Mediterranean Diet (MD), with an approximate daily intake of 1500 kcal for women and 1800 kcal for men (71% patients); Ketogenic Diet (KD), utilizing the VLCKD protocol characterized by a highly hypocaloric dietary regimen < 800 kcal/day (14% patients); metformin, administered using the oral formulation (5% patients); pharmacological intervention with GLP1-RA administered via subcutaneous injection with incremental dosage (10% patients). Supply constraints limited the efficacy of Liraglutide, whereas Semaglutide was excluded from comparisons due to its unavailability for obesity without diabetes. Blood tests were conducted to assess lipid profile, glycemic profile, and anthropometric parameters, including BMI, waist circumference, and waist-to-height ratio. RESULTS: Significant BMI changes were observed from baseline to 6 months across MD, KD, and Liraglutide groups (p < 0.05). KD exhibited notable reductions in waist circumference and waist-to-height ratio within the initial quarter (p < 0.05), with a significant triglyceride decrease after 6 months (p < 0.05), indicating its efficacy over MD. Liraglutide demonstrated a substantial reduction in HbA1c levels in the first quarter (p < 0.05). During the first three months, the ANOVA test on fasting blood glucose showed a statistically significant impact of the time variable (p < 0.05) rather than the specific treatments themselves (Liraglutide and KD), suggesting that adherence during the early stages of therapy may be more critical than treatment choice. CONCLUSIONS: Positive outcomes from targeted interventions, whether pharmacological or dietary should encourage the exploration of innovative, long-term strategies that include personalized treatment alternation. The absence of standardized protocols underscores the importance of careful and tailored planning in managing obesity as a chronic condition.

RESUMEN

AIMS: To identify and better understand themes related to why people living with obesity (PwO) in Canada may not use professional support and to explore potential strategies to address the challenges. METHODS: One-on-one interviews and online surveys, informed by the Theoretical Domains Framework, were conducted. A total of 20 PwO were interviewed and a separate group of 200 PwO were surveyed. Results from the interviews guided the development of the survey. Spearman's correlation analysis was performed to investigate the association between the theme domain scores of the PwO and their prior experience with obesity management strategies. RESULTS: The 200 PwO surveyed provided representation across Canada and were diverse in age, background and gender. The most prominent domains associated with use of professional support by PwO were: Intention (rs = -0.25; p < 0.01); Social/Professional Role and Identity (rs = -0.15; p < 0.05); and Optimism (rs = -0.15; p < 0.05). For example, PwO without professional support less often reported being transparent in obesity discussions, perceived obesity to be part of their identity, and expected to manage the illness long term. Many PwO hesitated to use various adjunctive therapies due to concerns about affordability, long-term effectiveness, and side effects. CONCLUSION: This study identified contextual, perception and resource considerations that contribute to healthcare decision-making and the use by PwO of professional support to manage obesity, and highlighted key areas to target with interventions to facilitate obesity management. Strategies such as consistent access to healthcare support and educational resources, as well as improved financial support may help PwO to feel more comfortable with exploring new strategies and take control of their healthcare.

RESUMEN

Over the past few decades, there has been a global surge in the prevalence of obesity, rendering it a globally recognized epidemic. Contrary to simply being a medical condition, obesity is an intricate disease with a multifactorial aetiology. Understanding the precise cause of obesity remains a challenge; nevertheless, there seems to be a complex interplay among biological, psychosocial and behavioural factors. Studies on the genetic factors of obesity have revealed several pathways in the brain that play a crucial role in food intake regulation. The best characterized pathway, thus far, is the leptin-melanocortin pathway, from which disruptions are responsible for the majority of monogenic obesity disorders. The effectiveness of conservative lifestyle interventions in addressing monogenic obesity has been limited. Therefore, it is crucial to complement the management strategy with pharmacological and surgical options. Emphasis has been placed on developing drugs aimed at replacing the absent signals, with the goal of restoring the pathway. In both monogenic and polygenic forms of obesity, outcomes differ across various interventions, likely due to the multifaceted nature of the disease. This underscores the need to explore alternative therapeutic strategies that can mitigate this heterogeneity. Precision medicine can be regarded as a powerful tool that can address this concern, as it values the understanding of the underlying abnormality triggering the disease and provides a tailored treatment accordingly. This would assist in optimizing outcomes of the current therapeutic approaches and even aid in the development of novel treatments capable of more effectively managing the global obesity epidemic.

RESUMEN

Metformin is a medication that is commonly prescribed to manage type 2 diabetes. It has been used for more than 60 years and is highly effective in lowering blood glucose levels. Recent studies indicate that metformin may have additional medical benefits beyond treating diabetes, revealing its potential therapeutic uses. Oral medication is commonly used to administer metformin because of its convenience and cost-effectiveness. However, there are challenges in optimizing its effectiveness. Gastrointestinal side effects and limitations in bioavailability have led to the underutilization of metformin. Innovative drug-delivery systems such as fast-dissolving tablets, micro/nanoparticle formulations, hydrogel and microneedles have been explored to optimize metformin therapy. These strategies enhance metformin dosage, targeting, bioavailability and stability, and provide personalized treatment options for improved glucose homeostasis, antiobesity and metabolic health benefits. Developing new delivery systems for metformin shows potential for improving therapeutic outcomes, broadening its applications beyond diabetes management and addressing unmet medical needs in various clinical settings. However, it is important to improve drug-delivery systems, addressing issues such as complexity, cost, biocompatibility, stability during storage and transportation, loading capacity, required technologies and biomaterials, targeting precision and regulatory approval. Addressing these limitations is crucial for effective, safe and accessible drug delivery in clinical practice. In this review, recent advances in the development and application of metformin-delivery systems for diabetes and obesity are discussed.

RESUMEN

PURPOSE OF REVIEW: Summarize the evolution of the trauma-informed care (TIC) approach in pediatrics, highlight the importance of using this lens in pediatric obesity management and treating the whole patient and family, and suggest recommendations for providers to incorporate TIC into their practice. RECENT FINDINGS: Implementing TIC in pediatric obesity management is recommended and offers an approach to address trauma-related symptoms associated with obesity. The TIC framework creates a safe, nurturing space to have open conversations with patients and families to promote resilience and reduce stigma related to obesity without re-traumatization. Screening tools may expose symptoms related to trauma, but are limited. Provider training is available and development of TIC related skills may be improved through using the arts and humanities. Success of TIC requires a tailored, integrated healthcare system approach with commitment from all levels. SUMMARY: The TIC approach offers providers skills to uncover trauma-related symptoms and address obesity-related health disparities while reducing stigma. Collaboration across all levels of the healthcare system and community partners is essential. Further research is warranted on the effectives of this approach in pediatric obesity prevention and management.

RESUMEN

Excess adiposity can contribute to metabolic complications, such as type 2 diabetes mellitus (T2DM), which poses a significant global health burden. Traditionally viewed as a chronic and irreversible condition, T2DM management has evolved and new approaches emphasizing reversal and remission are emerging. Bariatric surgery demonstrates significant improvements in body weight and glucose homeostasis. However, its complexity limits widespread implementation as a population-wide intervention. The identification of glucagon-like peptide 1 (GLP-1) and the development of GLP-1 receptor agonists (GLP-1RAs) have improved T2DM management and offer promising outcomes in terms of weight loss. Innovative treatment approaches combining GLP-1RA with other gut and pancreatic-derived hormone receptor agonists, such as glucose-dependant insulinotropic peptide (GIP) and glucagon (GCG) receptor agonists, or coadministered with amylin analogues, are demonstrating enhanced efficacy in both weight loss and glycemic control. This review aims to explore the benefits of bariatric surgery and emerging pharmacological therapies such as GLP-1RAs, and dual and triple agonists in managing obesity and T2DM while highlighting the caveats and evolving landscape of treatment options.

RESUMEN

OBJECTIVE: Obesity is the most prevalent chronic disease in the United States with over 70% of the American population suffering from overweight/obesity. Recently, the popularity of plant-based diets (PBDs) has grown, with individuals adopting these diets for ethical, health and environmental reasons. Our aim is to evaluate the effect of a PBD on weight loss among patients who are overweight or obese. METHODS: A literature review of PBDs for the treatment of obesity was conducted using PubMed and Scopus. Our search yielded 27 intervention trials (3361 participants) and 6 metanalyses (9168 participants, 61 trials). RESULTS: Among the intervention trials evaluated, 75% showed a significant increase in weight loss or decrease in weight in the intervention group, on average -5.0 kg (range -1.8 to -12.1 kg). Other outcomes included energy intake (-420 Kcal/d), systolic blood pressure (-3.78 mmHg), fasting plasma glucose (-2.0 mmol/L), hemoglobin A1c (-0.5%, -3.4 mmol/L), total cholesterol (-0.40 mmol/L), low-density lipoprotein (-0.38 mmol/L), triglyceride levels (+0.13 mmol/L), and fiber intake (+10.8 g/d). The 6 meta-analyses showed weight loss (average -2.9 kg, range -2.02 kg to -4.1 kg), body mass index reduction, and improvements in hemoglobin A1c, low-density lipoprotein, and total cholesterol. CONCLUSION: PBDs result in significant weight loss and improve metabolic outcomes. PBDs offer a sustainable approach to long-term weight loss maintenance. Health care providers should encourage open discussions with their patients regarding their dietary habits to assist them in setting feasible lifestyle goals and consider shared medical appointments to support patients in transitioning to PBDs.

RESUMEN

OBJECTIVE: To review clinical trial data for incretin therapies that are approved or in late-stage development for overweight or obesity management, along with clinical implications of these therapies and future directions. METHODS: We searched for clinical trials involving incretin therapies studied specifically for overweight or obesity management in ClinicalTrials.gov and PubMed from registry inception through December 2023. RESULTS: Glucagon-like peptide-1 (GLP-1) receptor agonism, alone and in combination with glucose-dependent insulinotropic polypeptide (GIP) receptor agonism or glucagon agonism, leads to significant weight reduction in people with overweight or obesity. Newer incretin therapies have demonstrated weight reduction between 15% to 25%, far outpacing non-incretin therapies for weight management and achieving levels of weight loss that may prevent weight-related complications. However, the discontinuation of incretin therapies is associated with weight regain. The main side effects of incretin therapies are transient, mild-to-moderate gastrointestinal side effects - nausea, diarrhea, constipation, and vomiting - that commonly occur in the first 4 to 8 weeks of treatment. There is a rich late-stage pipeline of incretin therapies for weight management, consisting of oral GLP-1 receptor agonists, dual GLP-1/GIP receptor agonists, dual GLP-1/glucagon receptor agonists, triple GLP-1/GIP/glucagon receptor agonists, and combination therapies with nonincretin drugs. CONCLUSION: Newer incretin therapies for weight management have the potential to improve the treatment for overweight and obesity, the treatment and prevention of weight-related complications, and the individualization of weight management. Ensuring that these therapies are accessible - and that treatment with them is consistent and sustainable - is necessary to translate findings from trials into the real world.

RESUMEN

Maternal obesity rates are increasing significantly, posing substantial risks to both mothers and their children. This study aims to introduce health policies addressing maternal obesity, identify preventive interventions, and highlight scientific gaps necessitating further research.We identified documents through electronic searches in PubMed, CINAHL Plus, EMBASE, and grey literature sources (ministry of health websites, national gynecology and obstetrics associations) from January 2013 to August 2023, updated in June 2024. The inclusion criteria focused on English-language documents discussing interventions or health policies that promote weight loss through lifestyle changes during pregnancy.A total of 22 documents (10 studies and 12 guidelines) were included. 12 studies (N=1244) identified via databases; included two Clinical Practice Guidelines (CPGs) from Canada and Singapore. Other 10 CPGs sourced from governmental websites and national associations: England (1), Australia (1), New Zealand (1), combined Australia and New Zealand (1), Canada (3), USA (1), Ireland (1), Germany (1). 10 guidelines focused on obesity in pregnancy, two on weight management during pregnancy. Covered interventions across pre-pregnancy, pregnancy, and postpartum periods (9 guidelines); pre-pregnancy and pregnancy (2); exclusively postpartum (1). Seven guidelines offered evidence-based recommendations on maintaining healthy weight in mothers, largely based on expert opinions.Maternal obesity poses significant risks to both mothers and children, underscoring the need for effective health policies and systems. However, few countries have integrated adequate responses into their healthcare policies and guidelines for professionals. Limited evidence exists on optimal practices to improve reproductive health outcomes in obese women. Hence, the crucial need to developing comprehensive guidelines and proactive strategies to manage maternal obesity. These measures can improve outcomes and reduce healthcare costs. Increased focus on research and policymaking is essential to protect the health of mothers and their children.

RESUMEN

BACKGROUND: Obesity is a chronic disease characterized by excess body fat and is a risk factor for other chronic non-communicable diseases. Its multifactorial and complex nature makes its management a challenge for health services. This manuscript presents an investigation protocol that aims to analyze the effectiveness of collective nutritional interventions for obesity management applicable to primary health care. METHODS: Randomized Controlled Community Trial (RCCT) in a representative sample of users of the Programa Academia de Saúde (PAS), in Belo Horizonte, Minas Gerais, Brazil, with obesity. The research consists of four phases: (1) Screening to identify the participants eligible for the nutritional interventions (individuals with obesity, readiness for change to lose body weight, and willingness and interest to participate in a group activity for six months or more); (2) Baseline to characterize the participants; (3) Implementation of collective nutritional interventions; (4) Reassessment of the participants. Participants in the control group (CG) will receive the usual health service care, and participants in the intervention group (IG) will participate in collective nutritional interventions based on Therapeutic Group 1 (TG1) or Therapeutic Group 2 (TG2) of the "Instructive of Collective Approach for the obesity management in SUS". DISCUSSION: The strengths of the study include its robust RCCT design, which allows for longitudinal analyses and is suitable for investigating causal hypotheses and applying strategies to improve adherence to interventions. Furthermore, the study included a representative sample of a public health service and aims to evaluate therapeutic proposals from the Brazilian Ministry of Health, which can contribute to implementation and extension in the national territory. TRIAL REGISTRATION: RBR-3vzsyqq and RBR-6pg682m.

RESUMEN

BACKGROUND: In light of the exponential rise in global population, there is a critical requirement to reduce food waste on a global scale. According to studies, agricultural wastes such as oil-seed cakes offer great nutritional value. Acid precipitation (A) and alkaline extraction methods (traditional methods) were used to extract protein from oil-seed cakes; however, both procedures are linked to decreased protein quality and quantity, which prompted the development of a novel strategy known as the biological/microbial/probiotic (B) method. Therefore, the present study aimed to highlight the optimal way of protein extraction from oil-seed cakes and the effect of extraction methods on protein efficacy against obesity. The outcomes were also compared with milk proteins. RESULTS: In vitro study provided evidence that proteins from both sources (plant and milk) suppressed adipogenesis and stimulated adipolysis in 3T3L-1 cells. For the in vivo study, mice were fed with different protein extracts: soya protein preparation (SPP), ground protein preparation (GPP), whey protein (WP) and casein protein (CP) containing 40% of their calories as fat. Body weight decreased significantly in all the rats except CP-fed rats. Body mass index, atherogenic index, plasma triglyceride and very-low-density lipoprotein cholesterol level decreased significantly in all the groups in comparison to the model group (high-fat-diet group), but the decrease was more pronounced in plant proteins than milk proteins. In hepatocytes, the expression of fasting-induced adipose factor, carnitine palmitoyltransferase I and peroxisome proliferator-activated receptor α genes was increased significantly in SPP-fed groups. Adiponectin gene expression was upregulated significantly in visceral fat tissue in groups fed SPP-B, GPP-A and CP, whereas leptin gene was downregulated significantly in all groups except SPP-A. CONCLUSION: This study demonstrates that SPP-B showed the most effective anti-obesity property, followed by WP. Additionally, we found that the biological precipitation approach produced better outcomes for plant proteins isolated from oil-seed cakes than the acid precipitation method. © 2023 Society of Chemical Industry.

RESUMEN

Obesity is now recognised as a disease that is associated with serious morbidity and increased mortality. One of its main metabolic complications is type 2 diabetes, as the two conditions share key pathophysiological mechanisms. Weight loss is known to reverse the underlying metabolic abnormalities of type 2 diabetes and, as such, improve glucose control; loss of 15% or more of bodyweight can have a disease-modifying effect in people with type 2 diabetes, an outcome that is not attainable by any other glucose-lowering intervention. Furthermore, weight loss in this population exerts benefits that extend beyond glycaemic control to improve risk factors for cardiometabolic disease and quality of life. We review the evidence supporting the role of weight loss in the management of type 2 diabetes and propose that many patients with type 2 diabetes would benefit from having a primary weight-centric approach to diabetes treatment. We discuss the logistical challenges to implementing a new weight-centric primary treatment goal in people with type 2 diabetes.

RESUMEN

BACKGROUND: Multicomponent lifestyle interventions are fundamental in pediatric obesity management. However, whether household food insecurity influences the efficacy of such interventions remains undocumented. OBJECTIVES: The objective was to compare changes in BMI z-score (BMIz) among children whose family received lifestyle counseling at a pediatric obesity management clinic in Montréal (Canada) according to their household food security status. METHODS: This is a retrospective, longitudinal analysis of medical records of children (2-17 y) with overweight or obesity who received lifestyle counseling at a pediatric obesity management clinic. The number of visits at the clinic and the duration of the follow-up were individualized. Household food security status was assessed using the Health Canada's Household Food Security Survey Module at the first visit at the clinic. BMIz was calculated and updated at each visit. A reduction of ≥0.25 in BMIz between the last and the first visit at the clinic was considered clinically meaningful. Statistical significance was considered at P < 0.05. RESULTS: Among the 214 children included in the study, 83 (38.8%) lived in a food insecure household. In multivariable-adjusted analyses, differences in BMIz between the last and the first appointment tended to be smaller among children who lived in a food insecure household than those in children living in a food secure household [ΔBMIzfood insecurity = -0.432 (95% CI: -0.672, -0.193) compared with ΔBMIzfood security = -0.556 (95% CI: -0.792, -0.319; P = 0.14)]. Differences were most notable in the first 6 mo of follow-up. The OR of achieving a clinically significant reduction in BMIz over follow-up associated with household food insecurity, compared with household food security, was 0.57 (95% CI: 0.31, 1.05; P = 0.07). CONCLUSIONS: In this sample of children followed up at a pediatric obesity clinic, those who lived in a food insecure household experienced smaller BMIz reductions than those who lived in a food secure household.

RESUMEN

Human genome research has reached new heights in the recent decade thanks to a major advance in genome editing. Genome editing enables scientists to understand better the functions of a single gene and its impact on a wide range of diseases. In brief, genome editing is a technique for introducing alterations into specific DNA sequences, such as insertions, deletions, or base substitutions. Several methods are adopted to perform genome editing and clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated nuclease 9 (Cas9) systems. Unfortunately, despite substantial progress in understanding the molecular pathways behind obesity, anti-obesity medications are now ineffective. If you are obese, a 10% weight decrease would be preferable to healthy body weight for most people. CRISPR-Cas9, on the other hand, has been shown to reduce body weight by an astonishing 20%. Hence, this updated review elaborates on the molecular basis of obesity, risk factors, types of gene therapy, possible mechanisms, and advantages of the CRISPR-Cas9 system over other methods.

RESUMEN

BACKGROUND: Practitioners' perceptions of patients with obesity and obesity management shape their engagement in obesity care delivery. This study aims to describe practitioners' perceptions, experiences and needs in managing patients with obesity, determine the extent of weight stigma among health practitioners, and identify the factors associated with negative judgment towards patients with obesity. METHODS: A cross-sectional online survey was conducted from May to August 2022 with health practitioners commonly involved in obesity management in Peninsular Malaysia, including doctors in primary care, internal medicine and bariatric surgery, and allied health practitioners. The survey explored practitioners' perceptions, barriers and needs in managing obesity, and evaluated weight stigma using the Universal Measures of Bias - Fat (UMB Fat) questionnaire. Multiple linear regression analysis was used to identify demographic and clinical-related factors associated with higher negative judgment towards patients with obesity. RESULTS: A total of 209 participants completed the survey (completion rate of 55.4%). The majority (n = 196, 94.3%) agreed that obesity is a chronic disease, perceived a responsibility to provide care (n = 176, 84.2%) and were motivated to help patients to lose weight (n = 160, 76.6%). However, only 22% (n = 46) thought their patients were motivated to lose weight. The most frequently reported barriers to obesity discussions were short consultation time, patients' lack of motivation, and having other, more important, concerns to discuss. Practitioners needed support with access to multi-disciplinary care, advanced obesity training, financing, comprehensive obesity management guidelines and access to obesity medications. The mean (SD) of the UMB Fat summary score was 2.99 (0.87), with the mean (SD) domain scores ranging between 2.21 and 4.36 (1.06 to 1.45). No demographic and clinical-related factors were significantly associated with negative judgment from the multiple linear regression analyses. CONCLUSION: Practitioners in this study considered obesity a chronic disease. While they had the motivation and capacity to engage in obesity management, physical and social opportunities were the reasons for not discussing obesity with their patients. Practitioners needed more support to enhance their capability and opportunity to engage with obesity management. Weight stigma in healthcare settings in Malaysia should be addressed, given the possibility of hindering weight discussions with patients.

RESUMEN

Importance: Obesity affects approximately 42% of US adults and is associated with increased rates of type 2 diabetes, hypertension, cardiovascular disease, sleep disorders, osteoarthritis, and premature death. Observations: A body mass index (BMI) of 25 or greater is commonly used to define overweight, and a BMI of 30 or greater to define obesity, with lower thresholds for Asian populations (BMI ≥25-27.5), although use of BMI alone is not recommended to determine individual risk. Individuals with obesity have higher rates of incident cardiovascular disease. In men with a BMI of 30 to 39, cardiovascular event rates are 20.21 per 1000 person-years compared with 13.72 per 1000 person-years in men with a normal BMI. In women with a BMI of 30 to 39.9, cardiovascular event rates are 9.97 per 1000 person-years compared with 6.37 per 1000 person-years in women with a normal BMI. Among people with obesity, 5% to 10% weight loss improves systolic blood pressure by about 3 mm Hg for those with hypertension, and may decrease hemoglobin A1c by 0.6% to 1% for those with type 2 diabetes. Evidence-based obesity treatment includes interventions addressing 5 major categories: behavioral interventions, nutrition, physical activity, pharmacotherapy, and metabolic/bariatric procedures. Comprehensive obesity care plans combine appropriate interventions for individual patients. Multicomponent behavioral interventions, ideally consisting of at least 14 sessions in 6 months to promote lifestyle changes, including components such as weight self-monitoring, dietary and physical activity counseling, and problem solving, often produce 5% to 10% weight loss, although weight regain occurs in 25% or more of participants at 2-year follow-up. Effective nutritional approaches focus on reducing total caloric intake and dietary strategies based on patient preferences. Physical activity without calorie reduction typically causes less weight loss (2-3 kg) but is important for weight-loss maintenance. Commonly prescribed medications such as antidepressants (eg, mirtazapine, amitriptyline) and antihyperglycemics such as glyburide or insulin cause weight gain, and clinicians should review and consider alternatives. Antiobesity medications are recommended for nonpregnant patients with obesity or overweight and weight-related comorbidities in conjunction with lifestyle modifications. Six medications are currently approved by the US Food and Drug Administration for long-term use: glucagon-like peptide receptor 1 (GLP-1) agonists (semaglutide and liraglutide only), tirzepatide (a glucose-dependent insulinotropic polypeptide/GLP-1 agonist), phentermine-topiramate, naltrexone-bupropion, and orlistat. Of these, tirzepatide has the greatest effect, with mean weight loss of 21% at 72 weeks. Endoscopic procedures (ie, intragastric balloon and endoscopic sleeve gastroplasty) can attain 10% to 13% weight loss at 6 months. Weight loss from metabolic and bariatric surgeries (ie, laparoscopic sleeve gastrectomy and Roux-en-Y gastric bypass) ranges from 25% to 30% at 12 months. Maintaining long-term weight loss is difficult, and clinical guidelines support the use of long-term antiobesity medications when weight maintenance is inadequate with lifestyle interventions alone. Conclusion and Relevance: Obesity affects approximately 42% of adults in the US. Behavioral interventions can attain approximately 5% to 10% weight loss, GLP-1 agonists and glucose-dependent insulinotropic polypeptide/GLP-1 receptor agonists can attain approximately 8% to 21% weight loss, and bariatric surgery can attain approximately 25% to 30% weight loss. Comprehensive, evidence-based obesity treatment combines behavioral interventions, nutrition, physical activity, pharmacotherapy, and metabolic/bariatric procedures as appropriate for individual patients.

RESUMEN

Metabolic disorders present a significant public health challenge globally. The intricate relationship between the gut microbiome, particularly Bacteroides spp. (BAC), and obesity, including their specific metabolic functions, remains partly unresolved. This review consolidates current research on BAC's role in obesity and lipid metabolism, with three objectives: (1) To summarize the gut microbiota's impact on obesity; (2) To assess BAC's efficacy in obesity intervention; (3) To explore BAC's mechanisms in obesity and lipid metabolism management. This review critically examines the role of BAC in obesity, integrating findings from clinical and preclinical studies. We highlight the changes in BAC diversity and concentration following successful obesity treatment and discuss the notable differences in BAC characteristics among individuals with varying obesity levels. Furthermore, we review recent preclinical studies demonstrating the potential of BAC in ameliorating obesity and related inflammatory conditions, providing detailed insights into the methodologies of these in vivo experiments. Additionally, certain BAC-derived metabolites have been shown to be involved in the regulation of host lipid metabolism-related pathways. The enhanced TNF production by dendritic cells following BAC administration, in response to LPS, also positions BAC as a potential adjunctive therapy in obesity management.

RESUMEN

OBJECTIVES: To examine characteristics of children referred for obesity management based on referral frequency, child- and referrer-related variables associated with re-referral, and determine whether re-referral increased treatment initiation. STUDY DESIGN: This population-level, retrospective analysis included all 2- to 17-year-olds referred for obesity management to 1 of 3 multidisciplinary clinics in Alberta, Canada between April 2013 and December 2017. Children were dichotomized based on referral frequency, specifically once only or more than once (re-referred). Data were retrieved from standardized referral forms and patient registries. Analyses included logistic regression and generalized estimating equations models. RESULT: We analyzed data from 2745 children (47.2% female; mean age: 11.4 years; mean body mass index z score: 3.03) and 2705 physicians (60.2% female; 65.6% pediatricians). Overall, 300 (10.2%) children were re-referred with most (n = 276; 92.0%) being referred twice. Children were less likely to be re-referred if they were referred by a family physician (vs pediatrician) (aOR 0.62; 95% CI 0.46-0.84; P = .0018) or scheduled a clinic appointment following their index referral (aOR: 0.29; 95% CI 0.21-0.4; P < .001). Treatment initiation was higher in children who were referred once only (42.1%) vs their re-referred peers (18.0%; P < .0001); however, for children who were re-referred, they were more likely to initiate treatment following their second referral (aOR 2.3; 95% CI 1.22-4.31; P = .01). This improvement was not sustained on subsequent referrals (aOR 0.44; 95% CI 0.17-1.12; P = .08). CONCLUSIONS: Few children were re-referred for pediatric obesity management; however, for those children who were re-referred, being re-referred once only increased the likelihood of treatment initiation.
