RESUMO
BACKGROUND: Sex disparity between metabolic-obesity (defined by body mass index, BMI) phenotypes and obesity-related cancer (ORC) remains unknown. Considering BMI reflecting overall obesity but not fat distribution, we aimed to systematically assess the association of our newly proposed metabolic-anthropometric phenotypes with risk of overall and site-specific ORC by sex. METHODS: A total of 141,579 men (mean age: 56.37 years, mean follow-up time: 12.04 years) and 131,047 women (mean age: 56.22 years, mean follow up time: 11.82 years) from the UK Biobank was included, and designated as metabolic-anthropometric phenotypes based on metabolic status (metabolically healthy/unhealthy), BMI (non-obesity/obesity) and body shape (pear/slim/apple/wide). The sex-specific association of different phenotypes with overall and site-specific ORC was assessed by hazard ratios (HRs) and 95% confidence intervals (CIs) using Cox proportional hazards regression models. RESULTS: We found metabolically unhealthy and/or obesity phenotypes conveyed a higher risk in men than in women for overall ORC and colorectal cancer compared with metabolically healthy non-obesity phenotype (Pinteraction < 0.05). Of note, metabolically healthy obesity phenotype contributed to increased risks of most ORC in men (HRs: 1.58 ~ 2.91), but only correlated with higher risks of endometrial (HR = 1.89, 95% CI: 1.54-2.32) and postmenopausal breast cancers (HR = 1.17, 95% CI: 1.05-1.31) in women. Similarly, even under metabolically healthy, men carrying apple and wide shapes phenotypes (metabolically healthy apple/wide and metabolically healthy non-obesity apple/wide) suffered an increased risk of ORC (mainly colorectal, liver, gastric cardia, and renal cancers, HRs: 1.20 ~ 3.81) in comparison with pear shape or non-obesity pear shape. CONCLUSIONS: There was a significant sex disparity between metabolic-anthropometric phenotypes and ORC risk. We advised future ORC prevention and control worth taking body shape and sex disparity into account.

OBJECTIVE: To examine the relationship between C-reactive protein (CRP) and knee pain, and further explore whether this association is mediated by obesity. METHODS: The population was derived from 1999 to 2004 National Health and Nutrition Examination Survey. Logistic regression was used to analyze the relationship between CRP and knee pain in three different models, and the linear trend was analyzed. A restricted cubic spline model to assess the nonlinear dose-response relationship between CRP and knee pain. Mediation analyses were used to assess the potential mediating role of obesity. Subgroup analyses and sensitivity analyses were performed to ensure robustness. RESULTS: Compared with adults with lower CRP (first quartile), those with higher CRP had higher risks of knee pain (odds ratio 1.39, 95% confidence interval 1.12-1.72 in third quartile; 1.56, 1.25-1.95 in fourth quartile) after adjusting for covariates (except body mass index [BMI]), and the proportion mediated by BMI was 76.10% (p < .001). BMI and CRP were linear dose-response correlated with knee pain. The odds ratio for those with obesity compared with normal to knee pain was 2.27 (1.42-3.65) in the first quartile of CRP, 1.99 (1.38-2.86) in the second, 2.15 (1.38-3.33) in the third, and 2.92 (1.72-4.97) in the fourth. CONCLUSION: Obesity mediated the systemic inflammation results in knee pain in US adults. Moreover, higher BMI was associated with higher knee pain risk in different degree CRP subgroups, supporting an important role of weight loss in reducing knee pain caused by systemic inflammation.

Obesity was mainly regarded as a disease of developed countries, but currently there is a growing rise in the population of patients with obesity in developing countries of Africa. A body mass index of 30 kg/m2 or higher is regarded as obesity, and this may be associated with comorbidities such as metabolic and cardiovascular diseases, orthopaedic and psychiatric conditions, and cancer. There is conclusive scientific evidence that shows that obesity is caused by complex psychosocial, genetic and environmental factors. Diet and exercise are not effective as sole management of severe obesity. Bariatric surgery is the most cost-effective definitive treatment for all classes of obesity, and the associated weight reduction causes improvement or complete resolution of obesity-associated comorbidity, improves the quality of life and reduces all-cause mortality. It is estimated that about 15% of adults in Nigeria are obese, and in the year 2023, it was reported that only 214 bariatric procedures were done locally, with 134 (62.6%) being gastric balloon insertions, 75 (35.1%) primary weight loss surgeries and 5 revisional surgeries (2.3%). In this article, we discussed the existing weight loss options in Nigeria, the current state of bariatric surgery and the need to improve the practice of bariatric surgery for obese Nigerians and complications of obesity.

Background: Obesity of companion animals in Canada is becoming a problem in veterinary practice. Cats and dogs, in particular, are increasingly overweight. However, prevention and treatment present challenges. Challenges in treating pet obesity, such as client nonadherence and animal welfare issues arising from obesity, also affect the well-being of veterinarians - especially given the coincident high rates of burnout and compassion fatigue experienced in the profession. Objective: This study investigated how practicing veterinarians perceive the treatment of overweight companion animals and how treating obese pets affects well-being of veterinarians. Animals and procedure: We recruited veterinarians who routinely treat companion animals in private practice to participate in focus group interviews. We also interviewed veterinarians who could not attend the focus group sessions, yet still wished to contribute. Through thematic data analysis, we generated key themes that illustrated how treating obese pets negatively affects veterinarian well-being. Results: Eighteen companion animal veterinarians contributed to this study. We generated 3 themes from the analysis that illustrate negative effects of treating obese pets on veterinarian well-being: i) negative feelings such as frustration and sadness associated with treating obese pets; ii) owners' lack of comprehension of the effects of obesity on pets, including early euthanasia; and iii) client nonadherence regarding treatment. Conclusion and clinical relevance: This study contributes to the veterinary literature on companion animal obesity by focusing on how treating pet obesity affects veterinarian well-being, especially given high rates of burnout and compassion fatigue in the profession. As pet obesity increases in society, obesity prevention and treatment is becoming central to companion animal veterinary practice. Our findings suggest that veterinarian well-being is negatively affected in connection with companion animal obesity. We recommend relationship-centered communication, increased nutritional expertise, and a focus on wellness in the workplace to improve veterinarian well-being while treating pet obesity.
Quand les vétérinaires traitent des animaux en surpoids : perspectives pour la pratique vétérinaire. Contexte: L'obésité des animaux de compagnie au Canada devient un problème dans la pratique vétérinaire. Les chats et les chiens, en particulier, sont de plus en plus en surpoids. Cependant, la prévention et le traitement présentent des défis. Les défis liés au traitement de l'obésité des animaux de compagnie, tels que la non-observance des traitements par les clients et les problèmes de bien-être animal liés à l'obésité, affectent également le bien-être des vétérinaires en particulier compte tenu des taux élevés d'épuisement professionnel et de fatigue de compassion que connaît la profession. Objectif: Cette étude a examiné comment les vétérinaires en exercice perçoivent le traitement des animaux de compagnie en surpoids et comment le traitement des animaux obèses affecte le bien-être des vétérinaires. Animaux et procédure: Nous avons recruté des vétérinaires qui traitent régulièrement des animaux de compagnie en cabinet privé pour participer à des entretiens de groupe. Nous avons également interrogé des vétérinaires qui n'avaient pas pu assister aux séances de groupe de discussion, mais qui souhaitaient néanmoins contribuer. Grâce à l'analyse thématique des données, nous avons généré des thèmes clés illustrant comment le traitement des animaux obèses affecte négativement le bien-être des vétérinaires. Résultats: Dix-huit vétérinaires d'animaux de compagnie ont contribué à cette étude. Nous avons généré 3 thèmes à partir de l'analyse qui illustrent les effets négatifs du traitement des animaux obèses sur le bien-être du vétérinaire : i) les sentiments négatifs tels que la frustration et la tristesse associés au traitement des animaux obèses; ii) le manque de compréhension des propriétaires des effets de l'obésité sur les animaux de compagnie, y compris l'euthanasie précoce; et iii) la non-observance du traitement par les clients. Conclusion et pertinence clinique: Cette étude contribue à la littérature vétérinaire sur l'obésité des animaux de compagnie en se concentrant sur la façon dont le traitement de l'obésité des animaux de compagnie affecte le bien-être des vétérinaires, en particulier compte tenu des taux élevés d'épuisement professionnel et de fatigue de compassion dans la profession. À mesure que l'obésité des animaux de compagnie augmente dans la société, la prévention et le traitement de l'obésité deviennent essentiels à la pratique vétérinaire des animaux de compagnie. Nos résultats suggèrent que le bien-être des vétérinaires est affecté négativement par l'obésité des animaux de compagnie. Nous recommandons une communication centrée sur les relations, une expertise nutritionnelle accrue et une concentration sur le bien-être au travail pour améliorer le bien-être des vétérinaires tout en traitant l'obésité des animaux de compagnie.(Traduit par Dr Serge Messier).

Adipose tissue (AT) serves as an energy-capacitive organ and performs functions involving paracrine- and endocrine-mediated regulation via extracellular vesicles (EVs) secretion. Exosomes, a subtype of EVs, contain various bioactive molecules with regulatory effects, such as nucleic acids, proteins, and lipids. AT-derived exosomes (AT-exos) include exosomes derived from various cells in AT, including adipocytes, adipose-derived stem cells (ADSCs), macrophages, and endothelial cells. This review aimed to comprehensively evaluate the impacts of different AT-exos on the regulation of physiological and pathological processes. The contents and functions of adipocyte-derived exosomes and ADSC-derived exosomes are compared simultaneously, highlighting their similarities and differences. The contents of AT-exos have been shown to exert complex regulatory effects on local inflammation, tumor dynamics, and insulin resistance. Significantly, differences in the cargoes of AT-exos have been observed among diabetes patients, obese individuals, and healthy individuals. These differences could be used to predict the development of diabetes mellitus and as therapeutic targets for improving insulin sensitivity and glucose tolerance. However, further research is needed to elucidate the underlying mechanisms and potential applications of AT-exos.

BACKGROUND: The number of individuals using digital health devices has grown in recent years. A higher rate of use in patients suggests that primary care providers (PCPs) may be able to leverage these tools to effectively guide and monitor physical activity (PA) for their patients. Despite evidence that remote patient monitoring (RPM) may enhance obesity interventions, few primary care practices have implemented programs that use commercial digital health tools to promote health or reduce complications of the disease. OBJECTIVE: This formative study aimed to assess the perceptions, needs, and challenges of implementation of an electronic health record (EHR)-integrated RPM program using wearable devices to promote patient PA at a large urban primary care practice to prepare for future intervention. METHODS: Our team identified existing workflows to upload wearable data to the EHR (Epic Systems), which included direct Fitbit (Google) integration that allowed for patient PA data to be uploaded to the EHR. We identified pictorial job aids describing the clinical workflow to PCPs. We then performed semistructured interviews with PCPs (n=10) and patients with obesity (n=8) at a large urban primary care clinic regarding their preferences and barriers to the program. We presented previously developed pictorial aids with instructions for (1) providers to complete an order set, set step-count goals, and receive feedback and (2) patients to set up their wearable devices and connect them to their patient portal account. We used rapid qualitative analysis during and after the interviews to code and develop key themes for both patients and providers that addressed our research objective. RESULTS: In total, 3 themes were identified from provider interviews: (1) providers' knowledge of PA prescription is focused on general guidelines with limited knowledge on how to tailor guidance to patients, (2) providers were open to receiving PA data but were worried about being overburdened by additional patient data, and (3) providers were concerned about patients being able to equitably access and participate in digital health interventions. In addition, 3 themes were also identified from patient interviews: (1) patients received limited or nonspecific guidance regarding PA from providers and other resources, (2) patients want to share exercise metrics with the health care team and receive tailored PA guidance at regular intervals, and (3) patients need written resources to support setting up an RPM program with access to live assistance on an as-needed basis. CONCLUSIONS: Implementation of an EHR-based RPM program and associated workflow is acceptable to PCPs and patients but will require attention to provider concerns of added burdensome patient data and patient concerns of receiving tailored PA guidance. Our ongoing work will pilot the RPM program and evaluate feasibility and acceptability within a primary care setting.

BACKGROUND: One anastomosis gastric bypass (OAGB) has gained prominence in the search for better results in bariatric surgery. However, its efficacy and safety compared to Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) remain ill-defined. AIMS: To compare the efficacy and safety of OAGB relative to RYGB and SG in the treatment of obesity. METHODS: We systematically searched PubMed, EMBASE, Cochrane Library, Lilacs, and Google Scholar databases for randomized controlled trials comparing OAGB with RYGB or SG in the surgical approach to obesity. We pooled outcomes for body mass index, percentage of excess weight loss, type-2 diabetes mellitus remission, complications, and gastroesophageal reflux disease. Statistical analyses were performed with R software (version 4.2.3). RESULTS: Data on 854 patients were extracted from 11 randomized controlled trials, of which 422 (49.4%) were submitted to OAGB with mean follow-up ranging from six months to five years. The meta-analysis revealed a significantly higher percentage of excess weight loss at 1-year follow-up and a significantly lower body mass index at 5-year follow-up in OAGB patients. Conversely, rates of type-2 diabetes mellitus remission, complications, and gastroesophageal reflux disease were not significantly different between groups. The overall quality of evidence was considered very low. CONCLUSIONS: Our results corroborate the comparable efficacy of OAGB in relation to RYGB and SG in the treatment of obesity, maintaining no significant differences in type-2 diabetes mellitus remission, complications, and gastroesophageal reflux disease rates.

Understanding the brain's mechanisms in individuals with obesity is important for managing body weight. Prior neuroimaging studies extensively investigated alterations in brain structure and function related to body mass index (BMI). However, how the network communication among the large-scale brain networks differs across BMI is underinvestigated. This study used diffusion magnetic resonance imaging of 290 young adults to identify links between BMI and brain network mechanisms. Navigation efficiency, a measure of network routing, was calculated from the structural connectivity computed using diffusion tractography. The sensory and frontoparietal networks indicated positive associations between navigation efficiency and BMI. The neurotransmitter association analysis identified that serotonergic and dopaminergic receptors, as well as opioid and norepinephrine systems, were related to BMI-related alterations in navigation efficiency. The transcriptomic analysis found that genes associated with network routing across BMI overlapped with genes enriched in excitatory and inhibitory neurons, specifically, gene enrichments related to synaptic transmission and neuron projection. Our findings suggest a valuable insight into understanding BMI-related alterations in brain network routing mechanisms and the potential underlying cellular biology, which might be used as a foundation for BMI-based weight management.

A healthy, balanced diet of a pregnant woman is an integral part for the full development of the fetus, mainly pregnant women receive the mentioned recommendations from gynecologists, because consulting a nutritionist is less mandatory at this stage still in our country. Since obesity is highly prevalent paralleling the globe, especially among the European population but nevertheless it's a preventable risk factor which is associated with negative outcomes for both mother and fetus. That's where bariatric surgery plays an important role, that has increased among women for an achievable pregnancy but being overweight prevents it. I have created a general medical booklet that would be useful to them as well, easy to understand and will bring positive results. This book shows the amount of calories to be consumed by pregnant mothers each trimester, kind of food to go for or should be avoided and type and duration of physical activity. That's where bariatric surgery plays an important role, that has increased among women for an achievable pregnancy, but being overweight prevents it. The crucial part to focus is how many months later the pregnancy occurred and how her nutrition was going. Being a pediatrician and nutritionist it's foremost important to observe mother and baby after the mentioned operation. Because monitoring the diet properly leads to better health in both mother and newborn since this topic is still lagging in research areas especially in European countries and data about obesity among pregnant women is lacking, so future studies would be beneficial among obese pregnant women for the betterment of their health.

Overweight and obesity affect 71.2% of adults in the United States, with cancer survivors not far behind at 70.3%. Subgroups such as those diagnosed with acute lymphoblastic leukemia (ALL) face even greater challenges. The Exercise and Quality Diet after Leukemia (EQUAL) trial sought to address weight management issues among ALL survivors by implementing a remotely delivered weight loss intervention, leveraging the previously proven Practice-based Opportunities for Weight Reduction (POWER) program. Despite a strong foundation and design, the EQUAL trial yielded null results. Key differences in study populations and intervention contexts between the EQUAL and POWER trials, such as the lack of primary care physician involvement in EQUAL, contributed to these outcomes. EQUAL's failure to meet its accrual target and poor adherence among participants highlighted challenges in engaging this unique population. Contrary to EQUAL's conclusions, evidence from other studies supports the efficacy of remote interventions for weight loss among cancer survivors. The lack of qualitative assessment among ALL survivors and key integration to inform intervention adaptations undermined EQUAL's impact. However, EQUAL's impressive retention rate offers valuable insights. Lessons from EQUAL underscore the need for well-fitted, remotely delivered interventions and the importance of thoughtfully adapted and tailored approaches to specific survivor populations.

Chronic inflammation in adipose tissue is thought to contribute to insulin resistance, which involves the gut microbiota. Our previous studies have demonstrated that ingestion of 1-kestose can alter the gut microbiota composition, increase cecal butyrate levels, and improve insulin resistance in Otsuka Long-Evans Tokushima Fatty (OLETF) rats. Additionally, we found that 1-kestose supplementation ameliorated insulin resistance in obese rat models fed a high-fat diet (HFD), although the effects of 1-kestose on the abundance of inflammation-related gene in adipose tissue and gut microbiota composition in these rats were not explored. This study aimed to investigate the impact of 1-kestose on these parameters in HFD-fed rats, compared to OLETF rats. Male Sprague-Dawley rats were divided into two dietary groups, control or HFD, for 19 wk. Each group was further subdivided to receive either tap water or tap water supplemented with 2% (w/v) 1-kestose throughout the study. We evaluated gene expression in adipose tissue, as well as short-chain fatty acids (SCFAs) levels and microbial composition in the cecum contents. 1-Kestose intake restored the increased relative abundance of tumor necrosis factor (Tnf) mRNA in adipose tissue and the reduced level of butyrate in the cecum contents of HFD-fed rats to those observed in control diet-fed rats. Additionally, 1-kestose consumption changed the composition of the gut microbiota, increasing Butyricicoccus spp., decreasing UGC-005 and Streptococcus spp., in the cecum contents of HFD-fed rats. Our findings suggest that 1-kestose supplementation reduces adipose tissue inflammation and increases butyrate levels in the gut of HFD-fed rats, associated with changes in the gut microbiota composition, distinct from those seen in OLETF rats.

Beige fat activation involves a fuel switch to fatty acid oxidation following chronic cold adaptation. Mitochondrial acyl-CoA synthetase long-chain family member 1 (ACSL1) localizes in the mitochondria and plays a key role in fatty acid oxidation; however, the regulatory mechanism of the subcellular localization remains poorly understood. Here, we identify an endosomal trafficking component sortilin (encoded by Sort1) in adipose tissues that shows dynamic expression during beige fat activation and facilitates the translocation of ACSL1 from the mitochondria to the endolysosomal pathway for degradation. Depletion of sortilin in adipocytes results in an increase of mitochondrial ACSL1 and the activation of AMPK/PGC1α signaling, thereby activating beige fat and preventing high-fat diet (HFD)-induced obesity and insulin resistance. Collectively, our findings indicate that sortilin controls adipose tissue fatty acid oxidation by substrate fuel selection during beige fat activation and provides a potential targeted approach for the treatment of metabolic diseases.

Improving access to kidney transplants remains a priority for the transplant community. However, many medical, psychosocial, geographic, and socioeconomic barriers exist that prevent or delay transplantation for candidates with certain conditions. There is a lack of consensus regarding how to best approach many of these issues and barriers, leading to heterogeneity in transplant centers' management and acceptance practices for a variety of pretransplant candidate issues. In this review, we address several of the more common contemporary patient medical and psychosocial barriers frequently encountered by transplant programs. The barriers discussed here include kidney transplant candidates with obesity, older age, prior malignancy, cardiovascular disease, history of nonadherence, and cannabis use. Improving understanding of how to best address these specific issues can empower referring providers, transplant programs, and patients to address these issues as necessary to progress toward eventual successful transplantation.

PURPOSE: The weight-adjusted waist index (WWI) is a recently developed index for measuring obesity. The aim of this study was to investigate the association between WWI levels and overactive bladder (OAB) in a nationally representative population. METHODS: This cross-sectional study used data from the National Health and Nutrition Examination Survey (NHANES) database between 2007 and 2016. OAB was defined as the Overactive Bladder Syndrome Symptom Score (OABSS, score ≥ 3). The WWI index was calculated as the square root of waist circumference (WC, cm) divided by body weight (kg). We used weighted logistic regression models to assess the relationship between the WWI index and OAB in adult women. The reliability of the findings was assessed using restricted cubic spline, subgroup analysis. RESULTS: A total of 10,563 individuals were included in the study, and the prevalence of OAB was 18.6%. Higher WWI was associated with an increased risk of overactive bladder syndrome. In model 1 with unadjusted variables (OR = 1.148; 95% CI = 1.148-1.149, p < 0.001), model 2 (OR = 1.253; 95% CI = 1.253-1.254, p < 0.001) and model 3 with fully adjusted variables (OR = 1.215; 95% CI = 1.214-1.215, p < 0.001) in which the association was significant. The results of the subgroup analyses showed that age stratification and stroke status could modify this association between WWI and OAB. Restricted cubic spline showed a nonlinear relationship between WWI and OAB (p for nonlinear < 0.05). CONCLUSION: Weight-adjusted waist circumference index (WWI) values are positively associated with the risk of developing OAB in adult women in the United States, but further studies are needed to elucidate the causal relationship between WWI and OAB.

BACKGROUND: Much remains unknown about how complex community-based programmes can successfully achieve long-term impact. More insight is needed to understand the key mechanisms through which these programmes work. Therefore, we conducted an in-depth study in five communities that implemented the Healthy Youth, Healthy Future (JOGG) approach, a Dutch community-based obesity prevention programme. We aimed to identify perceived outcomes and long-term impacts among local stakeholders and explore potential causal pathways and working mechanisms. METHODS: We used ripple effects mapping (REM), a qualitative participatory method to map outcomes and identify causal pathways, in five communities. We involved 26 stakeholders, professionals and policy-makers affiliated with the local JOGG approach, spread over eight REM sessions and conducted individual interviews with 24 additional stakeholders. To uncover working mechanisms, we compared outcomes and causal pathways across communities. RESULTS: Over 5-9 years of implementation, participants perceived that JOGG had improved ownership of local stakeholders, health policies, intersectoral collaboration and social norms towards promoting healthy lifestyles. Causal pathways comprised small initial outcomes that created the preconditions to enable the achievement of long-term impact. Although exact JOGG actions varied widely between communities, we identified five common working mechanisms through which the JOGG approach contributed to causal pathways: (1) creating a positive connotation with JOGG, (2) mobilizing stakeholders to participate in the JOGG approach, (3) facilitating projects to promote knowledge and awareness among stakeholders while creating successful experiences with promoting healthy lifestyles, (4) connecting stakeholders, thereby stimulating intersectoral collaboration and (5) sharing stakeholder successes that promote healthy lifestyles, which gradually created a social norm of participation. CONCLUSIONS: The JOGG approach seems to work through activating initial stakeholder participation and bolstering the process towards ownership, policy change, and intersectoral collaboration to promote healthy lifestyles. Key working mechanisms can inform further development of JOGG as well as other complex community-based prevention programmes.

BACKGROUND AND AIMS: Alcoholic beverages can be highly calorific yet remain largely absent from obesity policy debates. This article seeks to identify how Scottish and English obesity policies have engaged with the issue of alcohol consumption since devolution. METHODS: Obesity policy documents for England and Scotland from 1999 to 2023 were thematically analysed to identify their engagement with alcohol consumption. A stakeholder analysis was undertaken to identify key public health actors and commercial sector policy actors in the debate regarding the inclusion of alcohol in obesity policy. Their engagement with the issue of alcohol as an obesity policy issue was assessed through thematic analysis of consultation responses, along with documents, press releases, reports and other statements on policy (e.g. blog posts) available on stakeholder websites. RESULTS: While alcohol was recognised as a risk factor for obesity within obesity policy documents, no specific measures to address this issue were identified until a consultation on mandatory calorie labelling on alcoholic beverages was proposed in 2020. Engagement with alcohol in the policy documents was mainly limited to voluntary and self-regulatory measures favoured by industry actors who portrayed themselves as a key part of the policy solution. They used the policy focus on childhood obesity as a pretext to exclude alcoholic drink from fiscal and labelling measures. Public health NGOs, by contrast, argued that obesity measures such as mandatory calorie labelling and other obesity policies should be extended to alcoholic beverages. CONCLUSION: There is an insufficient engagement with alcohol as an obesity policy issue within policy documents and an over-reliance on voluntary and industry-partnership approaches. Alcoholic beverages and reduced alcohol products are excluded from beverage taxes and labelling requirements in ways which are hard to justify. As with other areas of public health policy, this represents an industry-favoured policy agenda, opposed by health NGOs. Further research is needed to understand the influence of these actors on the engagement of obesity policy with alcohol.

BACKGROUND: Elevated body mass index (BMI) is a known perioperative risk factor for complications such as delayed wound healing and infection. However, there is a gap in understanding how elevated BMI impacts outcomes after posttraumatic lower extremity (LE) microvascular reconstruction. METHODS: A retrospective review was performed at a level 1 trauma center between 2007 and 2022 of patients who underwent posttraumatic microvascular LE reconstruction. Demographics, flap/wound details, complications, and outcomes were recorded. Patients were stratified into BMI Center for Disease Control categories. RESULTS: A total of 398 patients were included with an average BMI of 28.2 ± 5.8. Nearly half (45%) of LE defects were located in the distal third of the leg, 27.5% in the middle third, and 34.4% in the proximal third. Most reconstructions utilized muscle-containing flaps (74.4%) compared with fasciocutaneous flaps (16.8%). Surgical approaches included free flaps (47.6%) and local flaps (52.5%). Class III obese patients were significantly more likely to be nonambulatory than nonobese patients (OR: 4.10, 95% CI 1.10-15.2, p = 0.035). At final follow-up, 30.1% of patients with Class III obesity were ambulatory, requiring either wheelchairs (42.3%) or assistance devices (26.9%). There were no significant differences in complication rates based on obesity status (0.704). The average follow-up time for the entire cohort was 5.8 years. CONCLUSIONS: BMI is critical for patient care and surgical decision-making in LE reconstruction. Further research is warranted to optimize outcomes for higher BMI patients, thereby potentially reducing the burden of postoperative complications and enhancing overall patient recovery.

BACKGROUND: With the increasing prevalence of obesity and type 2 diabetes, the availability of different treatment options remains essential. Studies comparing the outcomes of glucagon-like peptide 1 receptor agonists with those of metabolic bariatric surgery in patients with type 2 diabetes and obesity are lacking. METHODS: Using propensity score matching, based on data from several nationwide clinical registries, patients who underwent primary metabolic bariatric surgery (Roux-en-Y gastric bypass or sleeve gastrectomy) were matched with patients who received glucagon-like peptide 1 receptor agonists. Outcome measures included the occurrence of major cardiovascular events, microvascular complications, and potential side effects (alcohol/substance abuse, self-harm, and fractures). RESULTS: Over a mean follow-up of 7 years, major cardiovascular events occurred in 191 of 2039 patients (cumulative incidence 14.5%) in the surgery group compared with 247 of 2039 patients (19.6%) in the glucagon-like peptide 1 receptor agonist group (HR 0.75 (95% c.i. 0.62 to 0.91), P = 0.003). Patients in the surgery group had lower haemoglobin A1c values 5 years after treatment (mean difference 9.82 (95% c.i. 8.51 to 11.14)â mmol/mol, P < 0.001) and fewer microvascular complications (retinopathy HR 0.88 (95% c.i. 0.79 to 0.99), P = 0.039; nephropathy HR 0.72 (95% c.i. 0.66 to 0.80), P < 0.001; and neuropathy or leg ulcers HR 0.82 (95% c.i. 0.74 to 0.92), P < 0.001), but a higher risk of alcohol/substance abuse (HR 2.56 (95% c.i. 1.87 to 3.50), P < 0.001), self-harm (HR 1.41 (95% c.i. 1.17 to 1.71), P < 0.001), and fractures (HR 1.86 (95% c.i. 1.11 to 3.12), P = 0.019). CONCLUSION: Compared with glucagon-like peptide 1 receptor agonist treatment, metabolic bariatric surgery is associated with superior metabolic outcomes and a lower risk of major cardiovascular events in patients with type 2 diabetes and obesity, but a higher risk of alcohol/substance abuse, self-harm, and fractures.

Obesity is an important health concern that poses many public health challenges. Evidence-based treatment modalities, capable of cost-effectively reaching large patient groups are needed. In this paper, we present the design and methods of the updated national, 12-month, digital weight management program, the Healthy Weight Coaching (HWC). The major updates, as compared to the previous version, are related to the theoretical background of the obesity management and updated BMI cut-offs. The HWC is available, based on physicians' referrals, to adult Finnish citizens with BMI ≥30 kg/m2 or ≥27 kg/m2 with a comorbidity, who have a health-based need to lose weight. Rooted in the principles of behavioural therapy, the HWC focuses on teaching coping skills, guides to healthy self-reflection, and supports concrete lifestyle changes as part of healthy weight loss. The automated weekly training sessions, supplemented by 3-8 exercises, form the basis of the program. These sessions address topics such as diet, physical activity, stress management, and rest and recovery. Additionally, a personal coach is allocated to each patient to provide tailored support. At baseline, patients record their weight, height, and waist circumference, online, and complete questionnaires on lifestyle, diet, physical activity, sleep, psychological factors, and health. Thereafter weight recording is conducted at least every 4 weeks, while the questionnaires and measuring the weight circumference are repeated at 3, 6, 9, and 12 months. In addition, patients can make use of diaries and peer group chats for additional support. Data collected from the consenting patients will be used for research purposes with the weight change from baseline to 12 months as the main outcome in the real-life observational study. The study will provide invaluable insights into the application of digital modalities in the treatment of obesity.
