However, population-specific evidence for young adults remains limited. Herein, we provide a 20-year trend analysis of NAFLD in young adults and examine factors associated with NAFLD and major adverse cardiovascular events (MACE) prevalence. Methods: This study uses data from the United States National Health and Nutrition Examination Survey (NHANES) 1999-2018. Fatty liver was examined with the fatty liver index (FLI) and United States-FLI (US-FLI), and advanced fibrosis was examined with the fibrosis-4 index. Clustered multivariate logistic regression analysis on the year of study was applied to obtain odds ratios (OR) for the estimation of events. Results: 13.31% (95%CI: 12.71% to 13.94%) of young adults had NAFLD. The prevalence increased from 9.98% in 1999 to 19.49% in 2018, with a statistically significant trend (P < 0.001). 9.52% and 5.29% of patients have clinically significant and advanced fibrosis, respectively. In multivariate analysis, diabetes (3.48, 95%CI: 2.37 to 5.11), hypertension (2.03, 95%CI: 1.62 to 2.55), elevated body mass index (1.22, 95%CI: 1.20 to 1.23, P < 0.001) significantly increases odds of NAFLD. The largest increase in odds was related to obesity (OR: 21.61, 95%CI: 16.95 to 27.55, P < 0.001). Young adults with NAFLD had a borderline non-significant increase in the prevalence of MACE compared to individuals without NAFLD (OR: 1.603, 95%CI: 0.949 to 2.708, P = 0.078). Conclusion: The rising prevalence of NAFLD in young adults depicts the changing landscape of NAFLD and its association with a significant increase in MACE. The challenge of effective risk stratification and education of these individuals remains.","PeriodicalId":91001,"journal":{"name":"Metabolism and target organ damage","volume":"38 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67659428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, information using the new definition of the disease [i.e., metabolic dysfunction-associated fatty liver disease (MAFLD)] is scarce. We aimed to assess the relationship between MAFLD and CRA risk. Methods: We conducted a cross-sectional study including patients from three university centers in Chile who underwent a colonoscopy for colorectal cancer screening and abdominal imaging study. We obtained sociodemographic and clinical data, and we performed univariate and multivariable regression analyses. Results: In total, 895 patients were included; 42% were male, the mean age was 59.9 ± 9.3 years, and 37.8% (338) had CRA. Patients harboring polyps were predominantly males (48.2% vs. 38.2%, P = 0.002), older (61.6 ± 8.7 years vs. 58.9 ± 9.5 years, P < 0.001), and exhibited a higher body weight than controls [75 (66-88) kg vs. 72 (63-82.3) kg, P = 0.002]. Fifty-six percent of patients showed hepatic steatosis in imaging studies and 54.4% met MAFLD diagnostic criteria. The adenoma detection rate was higher in the MAFLD group compared to controls (46.4% vs. 27.5%, P < 0.001). In the multivariable analysis, MAFLD was significantly associated with the presence of CRA (odds ratio = 2.32; 95%CI: 1.68-3.19, P < 0.0001). There were no statistically significant differences of histopathological characteristics of the adenomas according to the presence of MAFLD. Conclusion: The present study shows that, in Chilean Hispanic subjects, MAFLD is associated with an increased risk of CRA. This information may be useful to design specific screening colonoscopy recommendations in MAFLD patients.","PeriodicalId":91001,"journal":{"name":"Metabolism and target organ damage","volume":"91 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67659484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pournaras","doi":"10.20517/mtod","DOIUrl":"https://doi.org/10.20517/mtod","url":null,"abstract":"People with diabetes mellitus (DM) undergo more elective surgery than those without DM; however, up to half of the patients are undiagnosed when referred for surgery. This is an opportunity to intervene and instigate a management plan. Preoperative strategies may vary based on coexisting medical diseases such as obesity and the availability of resources with the aim of achieving glycaemic control while also treating coexisting conditions. In the context of obesity, there is substantial overlap in some of the treatment strategies. Guidelines, such as those from the UK Centre for Perioperative Medicine, suggest target glycated haemoglobin levels, preoperative fasting blood glucose levels, and when to defer an elective operation or instigate treatment to proceed if deemed safe. Preoperatively glycaemic control is often achieved pharmacologically, and newer agents, including glucagon-like peptide one receptor agonists (GLP1-RA) and sodium-glucose co-transporter 2 (SGLT2) inhibitors, are emphasised in the preoperative management of diabetes mellitus, particularly if obesity is also present. A very low-energy diet is an underutilised but well-evidenced method of achieving both glycaemic control and weight loss with a particularly dominant effect on liver fat which is helpful for people who are due to undergo abdominal surgery. Bariatric-metabolic procedures are of growing interest as bridging interventions to surgery and are more commonly used for obesity, but they also have a well-recognized impact on the improvement and remission of DM. This review gives an overview of the necessity of preoperative identification of DM and strategies for management. Intra-operative glycaemic control is also discussed, and the role of stress hyperglycaemia perioperatively.","PeriodicalId":91001,"journal":{"name":"Metabolism and target organ damage","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67658863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this end, we briefly review the definitions and burdens of COPD and NAFLD and highlight the differences in the diagnostic criteria of NAFLD and MAFLD. We also critically discuss the recent line of research trying to identify an association between COPD and NAFLD. Moreover, among the chief co-morbidities of COPD patients, we identify significant six that exert a major impact on the natural course of COPD: major cardiovascular events, cardiac arrhythmias, metabolic syndrome, obstructive sleep apnea, osteoporosis, and psychodepression. The potential role of NAFLD in each of these COPD co-morbidities is accurately examined based on published studies. We conclude that both COPD and NAFLD/MAFLD are heterogeneous systemic syndromes. While the complex mechanistic links underlying the association of NAFLD/MAFLD with COPD and its co-morbidities remain to be fully elucidated, we highlight that the diagnosis of metabolic fatty liver syndromes in patients with COPD might be clinically relevant, as it might allow identifying a subset of COPD individuals who, being at risk of severe clinical outcomes, would need more comprehensive treatment approaches.","PeriodicalId":91001,"journal":{"name":"Metabolism and target organ damage","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67659205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data on TGR5 in human adipose tissue are very limited. Therefore, the aims of this study were to investigate TGR5 expression in visceral adipose tissue (VAT) and explore its association with signs of VAT dysfunction and overt metabolic disease in individuals with obesity. Methods: Fifty obese candidates to bariatric surgery were recruited at Sapienza University, Rome, Italy. The expression of TGR5 and markers of VAT dysfunction were assessed by rt-PCR in omental fragments obtained intraoperatively. Page 2 of Barchetta et al. Metab Target Organ Damage 2021;1:8 https://dx.doi.org/10.20517/mtod.2021.04 12 Results: Individuals with higher VAT TGR5 levels (high-TGR5) had greater fasting glucose (P = 0.027) and worse lipid profile (total-cholesterol, P = 0.014; LDL-cholesterol, P = 0.022) than those with lower TGR5 (low-TGR5) expression. High-TGR5 subjects showed significantly higher expression of markers of AT-specific inflammation and insulin resistance, such as tissue metallopeptidase inhibitor 1 (TIMP1; P = 0.011), poly[ADP-ribose]polymerase 1 (PARP1, P = 0.034), and WNT1-inducible-signaling pathway protein 1 (WISP1, P = 0.05), apoptosis (caspase 7, P = 0.031), and lipid trafficking (ANGPTL4, P < 0.001), compared to low-TGR5 patients. High VAT TGR5 expression predicted the presence of abnormal glucose metabolism with AUROC = 0.925 (95%CI: 0.827-1.00, P = 0.001) for the age-, sex-, and waist circumference-adjusted ROC curve.
