Time trends and disparities of obesity and related national policies and programs in Nepal:a systematic review

Objective Overweight and obesity prevalence has increased in low-income countries.This study systematically reviewed the obesity trend,disparities,and prevention and control efforts in Nepal.Methods We searched PubMed and Google Scholar for articles and reports published between January 1,2004 and December 31,2022.Additional information on National policies and programs related to obesity prevention was retrieved from governmental websites and consultation with relevant experts.Overweight and obesity were defined using the World Health Organization body mass index cut points.Thirty-two studies and reports were included.Results Overall,overweight and obesity rates increased in all groups in Nepal although nationally representative data remained limited.The combined overweight and obesity(OW/OB)and obesity rates in women aged 15-49 years increased from 8.5%to 22.2%and from 0.9%to 5.1%between 2006 and 2016,respectively.OW/OB and obesity rates in men were 17.1%and 2.5%based on data from the 2016 Demographic and Health Survey.OW/OB rate in under-five children increased from 0.6%to 2.8%between 2006 and 2016.Obesity rates for school-age(5-9 years)boys and girls in 2016 were 2.4%and 2.8%,respectively,and were 1.1%and 1.4%for male and female adolescents aged 10-19 years,respectively.OW/OB prevalence was much higher among women,residents in urban areas and central provinces,and in higher socioeconomic status groups.Projected prevalence of OW/OB and obesity for 2030 in adults aged 15-49 was 44.7%and 8.3%,respectively,while it was 2.2%for OW/OB in preschool children.Policies and direct interventions that specifically focused on obesity prevention and control are limited.Conclusions OW/OB prevalence in Nepal has increased during the past 1.8 decades,disproportionately affecting population groups.Existing interventions mostly focused on undernutrition with some indirect implications for obesity prevention.In the future,Nepal needs to develop population-based programs for obesity prevention.

Combating obesity in Southeast Asia countries:current status and the way forward

Obesity is gaining prominence as a serious public health challenge in the Southeast Asia(SEA)region,with an alarming rate of increase in its prevalence.Countries in the region have shown commitment to curbing the rise of obesity by establishing policies,strategies,and action plans.This paper summarises the current situation and strategies undertaken to combat obesity and related chronic diseases.Although a range of policies and strate-gies have been developed,including national nutrition action plans,community intervention programmes,fiscal measures,nutrition labelling to promote healthier choices,countries in the region are struggling to make signifi-cant progress toward halting the scourge of obesity.It is imperative to strengthen existing health systems with a paradigm shift from a focus on"sick care"to and enhancing nutrition initiatives to support obesity prevention.A comprehensive and coordinated approach is essential,one that emphasises high-level coordination across all lev-els of government and multiple sectors,and a unified plan rather than fragmented initiatives.For strategies to be effective and sustainable,they must address the fundamental environmental determinants of poor dietary choices and nutritional inequalities.A more holistic approach is clearly needed to improve the entire food environment,which in SEA countries must include the multitude of eating places where large segments of the population"eat out"everyday to meet their energy and nutrient needs.There is a recognised need for more comprehensive measures to promote healthy eating among school children and ensure a supportive environment for lifelong healthy habits.This paper calls for a whole-of-government,whole-of-society approach that combines changes to the fundamental food environment and accompanied by systematic monitoring and surveillance systems to achieve long-lasting health outcomes.

Clinical characteristics and treatment compounds of obesity-related kidney injury

Disorders in energy homeostasis can lead to various metabolic diseases,particularly obesity.The obesity epidemic has led to an increased incidence of obesityrelated nephropathy(ORN),a distinct entity characterized by proteinuria,glomerulomegaly,progressive glomerulosclerosis,and renal function decline.Obesity and its associated renal damage are common in clinical practice,and their incidence is increasing and attracting great attention.There is a great need to identify safe and effective therapeutic modalities,and therapeutics using chemical compounds and natural products are receiving increasing attention.However,the summary is lacking about the specific effects and mechanisms of action of compounds in the treatment of ORN.In this review,we summarize the important clinical features and compound treatment strategies for obesity and obesityinduced kidney injury.We also summarize the pathologic and clinical features of ORN as well as its pathogenesis and potential therapeutics targeting renal inflammation,oxidative stress,insulin resistance,fibrosis,kidney lipid accumulation,and dysregulated autophagy.In addition,detailed information on natural and synthetic compounds used for the treatment of obesity-related kidney disease is summarized.The synthesis of detailed information aims to contribute to a deeper understanding of the clinical treatment modalities for obesity-related kidney diseases,fostering the anticipation of novel insights in this domain.

Assessing Moroccan physician knowledge and practices regarding maternal obesity's impact on childhood obesity:Implications for prevention and intervention

BACKGROUND Childhood obesity is a growing global concern with far-reaching health implications.This study focuses on evaluating the knowledge and practices of physicians in Morocco regarding the link between maternal obesity and childhood obesity.Despite the increasing prevalence of childhood obesity worldwide,this issue remains inadequately addressed in the Moroccan context.AIM To assess the awareness and practices of physicians in Morocco concerning the connection between maternal obesity and childhood obesity.METHODS The research encompasses a comprehensive survey of practicing physicians,revealing significant gaps in awareness and practices related to maternal obesity.RESULTS Notably,a significant portion of doctors do not provide adequate guidance to overweight pregnant women,highlighting the urgency for targeted educational programs.CONCLUSION In conclusion,this research illuminates critical areas for improvement in tackling childhood obesity in Morocco.By addressing these gaps,fostering awareness,and enhancing medical practices,the healthcare system can contribute significantly to preventing childhood obesity and improving the overall health of future generations.

Selenoprotein-p and insulin resistance in children and adolescents with obesity

BACKGROUND Insulin resistance and obesity present significant challenges in pediatric populations.Selenoprotein P1(SEPP1)serves as a biomarker for assessing selenium levels in the body.While its association with metabolic syndrome is established in adults,its relevance in children remains underexplored.AIM To ascertain SEPP1 blood levels in children and adolescents diagnosed with obesity and to assess its correlation with insulin resistance and adiposity indices.METHODS 170 children participated in this study,including 85 diagnosed with obesity and an equal number of healthy counterparts matched for age and sex.Each participant underwent a comprehensive medical evaluation,encompassing a detailed medical history,clinical examination,and anthropometric measurements like waist circumference and waist-to-height ratio.Furthermore,routine blood tests were conducted,including serum SEPP1,visceral adiposity index(VAI),and Homeostatic Model Assessment of Insulin Resistance(HOMA-IR)level.RESULTS Our findings revealed significantly lower serum SEPP1 levels in children with obesity compared to their healthy peers.Moreover,notable negative correlations were observed between serum SEPP1 levels and body mass index,VAI,and HOMA-IR.CONCLUSION The study suggests that SEPP1 could serve as a valuable predictor for insulin resistance among children and adolescents diagnosed with obesity.This highlights the potential utility of SEPP1 in pediatric metabolic health assessment and warrants further investigation.

Management of male obesity-related secondary hypogonadism:A clinical update

The global obesity pandemic has resulted in a rise in the prevalence of male obesity-related secondary hypogonadism(MOSH)with emerging evidence on the role of testosterone therapy.We aim to provide an updated and practical approach towards its management.We did a comprehensive literature search across MEDLINE(via PubMed),Scopus,and Google Scholar databases using the keywords“MOSH”OR“Obesity-related hypogonadism”OR“Testosterone replacement therapy”OR“Selective estrogen receptor modulator”OR“SERM”OR“Guidelines on male hypogonadism”as well as a manual search of references within the articles.A narrative review based on available evidence,recommendations and their practical implications was done.Although weight loss is the ideal therapeutic strategy for patients with MOSH,achievement of significant weight reduction is usually difficult with lifestyle changes alone in real-world practice.Therefore,androgen administration is often necessary in the management of hypogonadism in patients with MOSH which also improves many other comorbidities related to obesity.However,there is conflicting evidence for the appropriate use of testosterone replacement therapy(TRT),and it can also be associated with complications.This evidence-based review updates the available evidence including the very recently published results of the TRAVERSE trial and provides comprehensive clinical practice pearls for the management of patients with MOSH.Before starting testosterone replacement in functional hypogonadism of obesity,it would be desirable to initiate lifestyle modification to ensure weight reduction.TRT should be coupled with the management of other comorbidities related to obesity in MOSH patients.Balancing the risks and benefits of TRT should be considered in every patient before and during longterm management.

Microbial phenolic metabolites 3-(3',4'-dihydroxyphenyl)propanoic acid and 3',4'-dihydroxyphenylacetic acid prevent obesity in mice fed high-fat diet

Obesity is associated with numerous metabolic disorders,and dietary polyphenols have been confirmed to have beneficial effects on the metabolism in obesity.However,the effect of 3-(3’,4’-dihydroxyphenyl)propanoic acid(DHPA)and 3’,4’-dihydroxyphenylacetic acid(DHAA),two main metabolites of dietary polyphenols,on obesity remains poorly understood.In this study,DHPA and DHAA were found to alleviate obesity,as well as regulate insulin resistance,lipid metabolism,and oxidative stress response in high-fat diet(HFD)mice.Surprisingly,the 16S rRNA sequencing and UHPLC-Q-TOF/MS demonstrated that DHPA and DHAA only slightly disturbed the intestinal microbiome,but significantly altered the urine metabolome of HFD mice mainly by regulating pentose and glucuronate interconversion,tyrosine metabolism,pentose phosphate and tricarboxylic acid(TCA)cycle as indicated by metabolic pathway analysis based on Kyoto Encyclopedia of Genes and Genomes(KEGG)database.Correlation analysis revealed that the differential metabolites are strongly associated with body weight,blood glucose,insulin level,and superoxide dismutase(SOD)enzyme activity.Our results revealed that DHPA and DHAA exert their anti-obesity effect by regulating important metabolites in the glucose,lipid and tyrosine metabolism pathways.

Association between childhood obesity and gut microbiota:16S rRNA gene sequencing-based cohort study

BACKGROUND This study aimed to identify characteristic gut genera in obese and normal-weight children(8-12 years old)using 16S rDNA sequencing.The research aimed to provide insights for mechanistic studies and prevention strategies for childhood obesity.Thirty normal-weight and thirty age-and sex-matched obese children were included.Questionnaires and body measurements were collected,and fecal samples underwent 16S rDNA sequencing.Significant differences in body mass index(BMI)and body-fat percentage were observed between the groups.Analysis of gut microbiota diversity revealed lowerα-diversity in obese children.Differences in gut microbiota composition were found between the two groups.Prevotella and Firmicutes were more abundant in the obese group,while Bacteroides and Sanguibacteroides were more prevalent in the control group.AIM To identify the characteristic gut genera in obese and normal-weight children(8-12-year-old)using 16S rDNA sequencing,and provide a basis for subsequent mechanistic studies and prevention strategies for childhood obesity.METHODS Thirty each normal-weight,1:1 matched for age and sex,and obese children,with an obese status from 2020 to 2022,were included in the control and obese groups,respectively.Basic information was collected through questionnaires and body measurements were obtained from both obese and normal-weight children.Fecal samples were collected from both groups and subjected to 16S rDNA sequencing using an Illumina MiSeq sequencing platform for gut microbiota diversity analysis.RESULTS Significant differences in BMI and body-fat percentage were observed between the two groups.The Ace and Chao1 indices were significantly lower in the obese group than those in the control group,whereas differences were not significant in the Shannon and Simpson indices.Kruskal-Wallis tests indicated significant differences in unweighted and weighted UniFrac distances between the gut microbiota of normal-weight and obese children(P<0.01),suggesting substantial disparities in both the species and quantity of gut microbiota between the two groups.Prevotella,Firmicutes,Bacteroides,and Sanguibacteroides were more abundant in the obese and control groups,respectively.Heatmap results demonstrated significant differences in the gut microbiota composition between obese and normal-weight children.CONCLUSION Obese children exhibited lowerα-diversity in their gut microbiota than did the normal-weight children.Significant differences were observed in the composition of gut microbiota between obese and normal-weight children.

Insights into the interplay between gut microbiota and lipid metabolism in the obesity management of canines and felines

Obesity is a prevalent chronic disease that has significant negative impacts on humans and our companion animals,including dogs and cats.Obesity occurs with multiple comorbidities,such as diabetes,hypertension,heart disease and osteoarthritis in dogs and cats.A direct link between lipid metabolism dysregulation and obesity-associated diseases has been implicated.However,the understanding of such pathophysiology in companion animals is lim-ited.This review aims to address the role of lipid metabolism in various metabolic disorders associated with obesity,emphasizing the involvement of the gut microbiota.Furthermore,we also discuss the management of obesity,including approaches like nutritional interventions,thus providing novel insights into obesity prevention and treatment for canines and felines.

New advances of adiponectin in regulating obesity and related metabolic syndromes

Obesity and related metabolic syndromes have been recognized as important disease risks,in which the role of adipokines cannot be ignored.Adiponectin(ADP)is one of the key adipokines with various beneficial effects,including improving glucose and lipid metabolism,enhancing insulin sensitivity,reducing oxidative stress and inflammation,promoting ceramides degradation,and stimulating adipose tissue vascularity.Based on those,it can serve as a positive regulator in many metabolic syndromes,such as type 2 diabetes(T2D),cardiovascular diseases,non-alcoholic fatty liver disease(NAFLD),sarcopenia,neurodegenerative diseases,and certain cancers.Therefore,a promising therapeutic approach for treating various metabolic diseases may involve elevating ADP levels or activating ADP receptors.The modulation of ADP genes,multimerization,and secretion covers the main processes of ADP generation,providing a comprehensive orientation for the development of more appropriate therapeutic strategies.In order to have a deeper understanding of ADP,this paper will provide an all-encompassing review of ADP.

Carbonic anhydrase 2 mediates anti-obesity effects of black tea as thermogenic activator

Obesity is a metabolic disorder due to over-accumulation of adipose tissue and ultimately becomes a“disease”.Brown adipose tissue(BAT)thermogenesis and white adipose tissue(WAT)browning emerge as a potential strategy of anti-obesity by dissipating energy as heat.However,drugs based on adipose tissue thermogenesis have not been successfully approved yet.In current study,we found that black tea extract(BTE)obtained by patentauthorized manufacturing process prevented body weight gain as novel thermogenic activator with reduction of adiposity,improvement of adipose distribution,and glucose metabolism improvement in diet-induced obesity mice.Mechanismly,anti-obesity effect of BTE depends on promoting BAT thermogenesis and WAT browning with upregulation of uncoupling protein 1(UCP1),especially visceral adipose tissue(VAT)with browning resistance.Specifically,utilizing in silico approach of network pharmacology and molecular docking,we identified carbonic anhydrase 2(CA2)in nitrogen metabolism as anti-obesity target of BTE and further elucidated that protein kinase B(AKT)signaling pathway linked CA2 and UCP1.Meanwhile gut microbiota regulation may prompt the CA2-dependent thermogenesis activation.Our findings demonstrated anti-obesity effect of BTE as thermogenic activator through CA2-mediated BAT thermogenesis and WAT browning via CA2-AKT-UCP1 signaling pathway,which could be developed as promising anti-obesity agent with good safety and efficacy.

Association of Serum Folate and Vitamin B_(12) Concentrations with Obesity in Chinese Children and Adolescents

Objective This study aimed to evaluate the associations of serum folate and/or vitamin B12 concentrations with obesity among Chinese children and adolescents.Methods A cross-sectional study was conducted including 3,079 Chinese children and adolescents,aged 6 to 17 years,from Jiangsu,China.Anthropometric indices,such as,children's body mass index(BMI),BMI z-scores,waist circumference,and waist-to-height ratio were utilized.Multivariable linear regression and generalized additive models were used to investigate the associations of serum folate and vitamin B12 levels with anthropometric indices and odds of obesity.Results We observed that serum vitamin B12 concentrations were inversely associated with all anthropometric indices and the odds of general obesity[odds ratio(OR)=0.68;95%confidence interval(CI)=0.59,0.78]and abdominal obesity(OR=0.68;95%CI=0.60,0.77).When compared to participants with both serum vitamin levels in the two middle quartiles,those with both serum folate and vitamin B12 levels in the highest quartile were less prone to general(OR=0.31,95%CI=0.19,0.50)or abdominal obesity(OR=0.46,95%CI=0.31,0.67).Conversely,participants with vitamin B12 levels in the lowest quartile alongside folate levels in the highest quartile had higher odds of abdominal obesity(OR=2.06,95%CI=1.09,3.91).Conclusion Higher serum vitamin B12 concentrations,but not serum folate concentrations,were associated with lower odds of childhood obesity.Children and adolescents with high levels of vitamin B12 and folate were less likely to be obese.

Transcriptome analysis suggests broad jejunal alterations in Linghu’s obesity-diarrhea syndrome:A pilot study

BACKGROUND Obesity is associated with a significantly increased risk for chronic diarrhea,which has been proposed as Linghu’s obesity-diarrhea syndrome(ODS);however,its molecular mechanisms are largely unknown.AIM To reveal the transcriptomic changes in the jejunum involved in ODS.METHODS In a cohort of 6 ODS patients(JOD group),6 obese people without diarrhea(JO group),and 6 healthy controls(JC group),high-throughput sequencing and bioinformatics analyses were performed to identify jejunal mucosal mRNA expression alterations and dysfunctional biological processes.In another cohort of 16 ODS patients(SOD group),16 obese people without diarrhea(SO group),and 16 healthy controls(SC group),serum diamine oxidase(DAO)and D-lactate(DLA)concentrations were detected to assess changes in intestinal barrier function.RESULTS The gene expression profiles of jejunal mucosa in the JO and JC groups were similar,with only 1 differentially expressed gene(DEG).The gene expression profile of the JOD group was significantly changed,with 411 DEGs compared with the JO group and 211 DEGs compared with the JC group,129 of which overlapped.The enrichment analysis of these DEGs showed that the biological processes such as digestion,absorption,and transport of nutrients(especially lipids)tended to be up-regulated in the JOD group,while the biological processes such as rRNA processing,mitochondrial translation,antimicrobial humoral response,DNA replication,and DNA repair tended to be down-regulated in the JOD group.Eight DEGs(CDT1,NHP2,EXOSC5,EPN3,NME1,REG3A,PLA2G2A,and PRSS2)may play a key regulatory role in the pathological process of ODS,and their expression levels were significantly decreased in ODS patients(P<0.001).In the second cohort,compared with healthy controls,the levels of serum intestinal barrier function markers(DAO and D-LA)were significantly increased in all obese individuals(P<0.01),but were higher in the SOD group than in the SO group(P<0.001).CONCLUSION Compared with healthy controls and obese individuals without diarrhea,patients with Linghu’s ODS had extensive transcriptomic changes in the jejunal mucosa,likely affecting intestinal barrier function and thus contributing to the obesity and chronic diarrhea phenotypes.

The Association between GLP-1 Receptor-Based Agonists and the Incidence of Asthma in Patients with Type 2 Diabetes and/or Obesity:A Meta-Analysis

Objective Recent studies have indicated potential anti-inflammatory effects of glucagon-like peptide-1 receptor agonists(GLP-1RAs)on asthma,which is often comorbid with type 2 diabetes mellitus(T2DM)and obesity.Therefore,we conducted a meta-analysis to assess the association between the administration of glucagon-like peptide-1(GLP-1)receptor-based agonists and the incidence of asthma in patients with T2DM and/or obesity.Methods PubMed,Web of Science,Embase,the Cochrane Central Register of Controlled Trials,and Clinicaltrial.gov were systematically searched from inception to July 2023.Randomized controlled trials(RCTs)of GLP-1 receptor-based agonists(GLP-1RA,GLP-1 based dual and triple receptor agonist)with reports of asthma events were included.Outcomes were computed as risk ratios(RR)using a fixedeffects model.Results Overall,39 RCTs with a total of 85,755 participants were included.Compared to non-GLP-1 receptor-based agonist users,a trend of reduced risk of asthma was observed in patients with T2DM or obesity using GLP-1 receptor-based agonist treatments,although the difference was not statistically significant[RR=0.91,95%confidence interval(CI):0.68 to 1.24].Further Subgroup analyses indicated that the use of light-molecular-weight GLP-1RAs might be associated with a reduced the risk of asthma when compared with non-users(RR=0.65,95%CI:0.43 to 0.99,P=0.043).We also performed sensitivity analyses for participant characteristics,study design,drug structure,duration of action,and drug subtypes.However,no significant associations were observed.Conclusion Compared with non-users,a modest reduction in the incidence of asthma was observed in patients with T2DM or obesity using GLP-1 receptor-based agonist treatments.Further investigations are warranted to assess the association between GLP-1 receptor-based agonists and the risk of asthma.

Polysaccharides of Aspergillus cristatus attenuate obesity by regulating gut microbiota and gut microbiota-related metabolites

Golden-flower fungus,the only dominant microorganism determining the Fu-brick tea quality through fermentation and the important microbe in Liupao tea,is considered a potential probiotic fungus based on its anti-obesity effect.However,the classification of golden-flower fungi is still controversial;the anti-obesity effect of golden-flower fungus polysaccharides remains unknown.In this study,we identify a golden-flower strain as Aspergillus cristatus based on morphological characteristics and multigene phylogeny analysis,which resolves the controversy of classification.Moreover,we find A.cristatus polysaccharides(ACPS)attenuate obesity in rats.ACPS modulate gut bacterial composition.in which Akkermansia,Akkermansia muciniphila,Bacteroides,Romboutsia,Blautia,and Desulfovibrio are considered the core microbes regulated by ACPS.ACPS increase fecal total short-chain fatty acid content and serum,hepatic,and fecal total bile acid content.Furthermore,ACPS-induced gut microbiota alteration plays a causal role in the protection from obesity,according to a fecal transplantation experiment.Thus,ACPS ameliorate obesity by regulating gut microbiota and gut microbiota-related metabolites.

Junshanyinzhen tea extract prevents obesity by regulating gut microbiota and metabolic endotoxemia in high-fat diet fed rats

Obesity is associated with gut dysbiosis and metabolic endotoxin.Junshanyinzhen tea extract(JSTE)reduced fat accumulation and body weight in obese mice.However,the effects and mechanism of JSTE in preventing obesity were unclear.Therefore,we used different doses of JSTE(75,150 and 300 mg/(kg·day))to evaluate the effect on high-fat diet(HFD)-induced rats under 8 weeks of intervention.Here,our results showed that JSTE could significantly reduce body weight gain,blood lipid levels and fat accumulation,improve fatty damage in liver tissue(P<0.05).In addition,JSTE increased the expression of intestinal tight junction proteins(P<0.05),relieved metabolic endotoxemia(P<0.05)and chronic low-grade inflammation in HFD rats.Sequencing of fecal samples showed that JSTE could effectively reverse the microbial diversity and the ratio of Firmicutes to Bacteroidetes to normal levels in HFD-fed rats.Desulfovibrioceae and Erysipelotrichaceae,which are positively related to obesity,were decreased by JSTE intervention(P<0.05).while Bifidobacteriaceae,Bacteroidaceae,Akkermansia,and Clostridium,which are negatively related to obesity,were increased.Together,these results suggested that JSTE might effectively prevent obesity by modulating gut microbiota dysbiosis,intestinal barrier dysfunction,metabolic endotoxemia and chronic low-grade infl ammation in HFD-induced rats.

The 10th China Obesity Science Conference Held in Beijing

The 10th China Obesity Science Conference was held in Beijing from May 10th to 11th, 2024. Experts from authoritative institutions such as the National Health Commission, the Chinese Center for Disease Control and Prevention, and the China Institute of Sports Science gathered to discuss on the topics including obesity prevalence trends.

Novel subtype of obesity influencing the outcomes of sleeve gastrectomy:Familial aggregation of obesity

BACKGROUND Differences in the preoperative characteristics and weight loss outcomes after sleeve gastrectomy(SG)between patients with familial aggregation of obesity(FAO)and patients with sporadic obesity(SO)have not been elucidated.AIM To explore the impact of SG on weight loss and the alleviation of obesity-related comorbidities in individuals with FAO.METHODS A total of 193 patients with obesity who underwent SG were selected.Patients with FAO/SO were matched 1:1 by propensity score matching and were categorized into 4 groups based on the number of first-degree relatives with obesity(1 SO vs 1FAO,2SO vs 2FAO).The baseline characteristics,weight loss outcomes,prevalence of obesity-related comorbidities and incidence of major surgeryrelated complications were compared between groups.RESULTS We defined FAO as the presence of two or more first-degree relatives with obesity.Patients with FAO did not initially show significant differences in baseline data,short-term postoperative weight loss,or obesity-related comorbidities when compared to patients with SO preoperatively.However,distinctions between the two groups became evident at the two-year mark,with statistically significant differences in both percentage of total weight loss(P=0.006)and percentage of excess weight loss(P<0.001).The FAO group exhibited weaker remission of type 2 diabetes mellitus(T2DM)(P=0.031),hyperlipidemia(P=0.012),and non-alcoholic fatty liver disease(NAFLD)(P=0.003)as well as a lower incidence of acid reflux(P=0.038).CONCLUSION FAO patients is associated with decreased mid-to-long-term weight loss outcomes;the alleviation of T2DM,hyperlipidemia and NAFLD;and decreased incidence of acid reflux postoperatively.

Link between childhood obesity and gut microbiota

Childhood obesity is a critical global health concern with rising prevalence and significant long-term health implications.Recent studies have implicated gut microbiota in the development and progression of obesity.This editorial analyzes the research conducted by Li et al,who utilized 16S rRNA gene sequencing to compare the gut microbiome of overweight and healthy-weight children.The study found significant differences in microbial diversity and composition between the two groups,with potential implications for understanding and managing childhood obesity.We analyzed the study’s advantages and drawbacks,proposing potential areas for future research to better understand the connection between gut microbiota and obesity.

Akkermansia muciniphila-directed polyphenol chlorogenic acid intervention for obesity in mice

Akkermansia muciniphila play an important in ameliorating obesity but is not allowed for direct consumption in most countries.To date,microbiota-directed foods selectively promote the targeted human gut microbes,providing a strategy for A.muciniphila enhancement.Multiple studies have indicated the potential regulation of the polyphenol on A.muciniphila.Therefore,a polyphenol screening based on A.muciniphila upregulation was performed in mice.Chlorogenic acid(CGA)exhibited a greater response to A.muciniphila upregulation.Furthermore,we found that CGA did not directly promote A.muciniphila growth or mucin secretion.Microbiome and metabolomics revealed that the increased abundance of A.muciniphila resulted from the inhibition of CGA on Desulfovibrio and Alistipes and the influence of docosahexaenoic acid,β-hydroxybutyrate,and N-acetyl-lactosamine.Finally,to confirm the regulation of CGA on A.muciniphila under disease conditions,high-fat diet-fed mice were established.The results showed CGA promoted A.muciniphila growth,and we expectedly found that CGA suppressed the augment in body weight of mice,significantly attenuated adipose tissue abnormality,provided liver protection and improved gut barrier integrity.These results suggest that CGA inhibits the development of obesity.Overall,our results indicate that microbiota-directed food is a promising approach for the treatment of obesity.
