Abstract
BACKGROUND AND AIMS Clinical observation revealed an increase in metabolic dysfunction-associated steatotic liver disease (MASLD) prevalence among adults and adolescents and young adults (AYA). However, its prevalence trend in specific subgroups and its characteristics are unclear. APPROACH AND RESULTS This cross-sectional study included adults and AYA aged 20-79 and 12-19 years, respectively, from the National Health and Nutrition Examination Survey from 1999 to 2018. MASLD was defined as US Fatty Liver Index ≥30 in adults and alanine amino transaminase elevation and obesity in AYA. Joinpoint and logistic regression were used to evaluate the MASLD prevalence trend and its associated characteristics. MASLD was diagnosed in 17 156 892 of 51 109 914 (33.6%) adults and 1 705 586 of 29 278 666 AYA (5.8%). During the study period, MASLD prevalence significantly increased from 30.8% to 37.7% ( P < 0.01) in adults and in subgroups of female participants, individuals aged 20-45 and 61-79 years, and non-Hispanic white individuals. Conversely, MASLD prevalence did not significantly change in AYA (from 5.1% to 5.2%, P = 0.139), except in the subgroup of Mexican Americans (from 8.2% to 10.8%, P = 0.01). Among adults, high MASLD prevalence was associated with male sex, Mexican American ethnicity, age >50 years, being unmarried, poverty income ratio <130, poor or fair health condition, obesity or overweight, and chronic conditions. Among AYA, high MASLD prevalence was associated with male sex, poverty income ratio <130, and education. CONCLUSION Accordingly, we concluded that health care providers should prevent and treat conditions associated with MASLD by raising awareness of the increasing trend of MASLD.

J Clin Endocrinol Metab 2024; 109:1241-1249. [PMID: 38051959 DOI: 10.1210/clinem/dgad710] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Revised: 11/03/2023] [Accepted: 12/03/2023] [Indexed: 12/07/2023]
Abstract
OBJECTIVE We aimed to examine the expression profile and circulating level of hypoxia-inducible factor 1 alpha (HIF1α) in children and the relationships with metabolic disorders. METHODS A total of 519 children were recruited, with paired subcutaneous and omental adipose tissues collected from 17 children and serum samples from the remaining children. All children underwent anthropometric and biochemical analyses. The mRNA, protein, and serum levels of HIF1α were determined by real-time PCR, immunohistochemistry, and enzyme-linked immunosorbent assay, respectively. RESULTS Both HIF1α mRNA and protein levels, especially in omental adipose tissue, were increased in overweight or obese (OV/OB) children (P < .05). Likewise, serum HIF1α level was remarkably higher in OV/OB children than in normal-weight children (P < .05). Serum HIF1α level was positively correlated with BMI z-score, fat mass percentage, waist to height ratio, systolic blood pressure, alanine aminotransferase, total triglycerides, uric acid, and homeostasis model assessment of insulin resistance (IR). Furthermore, a binary logistic regression analysis of serum HIF1α level indicated that the risks for IR, nonalcoholic fatty liver disease (NAFLD), and metabolic syndrome remained significant in the presence of all potential confounding variables. Finally, the area under the receiver operating characteristic curves for serum HIF1α level in children who were diagnosed with IR, NAFLD, and metabolic syndrome were 0.698 (95% CI, 0.646-0.750; P < .001), 0.679 (95% CI, 0.628-0.731; P < .001), and 0.900 (95% CI, 0.856-0.945; P < .001). CONCLUSION HIF1α expression is higher in the adipose tissue, especially omental, of children with obesity than in children with normal weight. Elevated serum HIF1α level is associated with adiposity and metabolic disorder, which may predict a higher risk of obesity complications.

Abstract
Nonalcoholic fatty liver disease (NAFLD), which can manifest as nonalcoholic steatohepatitis (NASH) or severe fibrosis, is the most prevalent chronic liver disease in children and adolescents. However, there is no proven cure for it so far. This study was conducted to determine whether adolescents with NAFLD would improve with treatment intervention with orlistat. This study is a randomized controlled trial (RCT). Fifty-three adolescents with overweight/obese as well as with NAFLD randomly allocated to receive orlistat (n = 27) or placebo as control (n = 26) for 12 weeks. In addition, NAFLD activity score, anthropometric factors, biochemical parameters including serum levels of lipid profiles, liver enzyme, and glucose metabolism taken from subjects at baseline and end of the study were investigated. The findings of our article indicated that orlistat improves liver enzymes (alanine transaminase and aspartate transaminase) (P = < 0.001), steatosis score (P = 0.001), NAFLD activity score (P = < 0.001), weight (P = < 0.001), body mass index (BMI) (P = < 0.001), waist circumferences (WC) (P = < 0.001), BMI-Z score (P = < 0.001), glucose metabolism (P = 0.001), total cholesterol (TC) (P = 0.009), low density lipoprotein-cholesterol (LDL) (P = < 0.001), and high density lipoprotein-cholesterol HDL levels (P = 0.014) compared to the control group after adjusting for possible confounders for 12 weeks. However, no significant changes were observed on triglyceride (TG) following intake of orlistat compared to placebo after adjusting for confounders. CONCLUSION The findings of our study reported that orlistat improved NAFLD-related factors and metabolic syndrome-related factors compared to placebo for 12 weeks. TRIAL REGISTRATION (Clinical trial registry number: IRCT20220409054467N2, with a registration date of 2022-05-13). WHAT IS KNOWN • Among the interventions of interest for the management of pediatric NAFLD, we can mention lifestyle and pharmaceutical measures. WHAT IS NEW • This study was conducted to determine whether adolescents with NAFLD would improve with treatment intervention with orlistat. • The findings of our study reported that orlistat improved NAFLD-related factors and metabolic syndrome-related factors compared to placebo for 12 weeks.

Abstract
BACKGROUND Non-alcoholic fatty liver disease (NAFLD) is rapidly increasing alongside overweight and obesity, not only in adults but also in children and adolescents. It is unknown what impact the development of NAFLD in childhood may have in later life. The importance of early detection and treatment lies in its potential for progression to cirrhosis, liver cancer and liver-related death, as well as its associated extrahepatic comorbidities. Vibration-Controlled Transient Elastography (VCTE) with Controlled Attenuation Parameter (CAP) is an effective, non-invasive and safe diagnostic method to estimate the degree of fibrosis and steatosis in the liver, but little is known about its applicability in the paediatric population. AIMS 1) To assess the prevalence of significant liver fibrosis (Liver Stiffness Measurement (LSM) ≥6.5 kPa) using VCTE, and that of non-alcoholic fatty liver disease (≥225 dB/m) using CAP in children and adolescents. 2) To determine the optimal cut-off points of the CAP to achieve maximum concordance with the Magnetic Resonance Imaging (MRI) findings in the diagnosis of mild, moderate and severe NAFLD in children and adolescents. METHODS Cross-sectional population-based study which will include 2,866 subjects aged between 9 and 16 years. Participants will undergo: anamnesis, physical examination, blood extraction, VCTE, MRI and questionnaires on socio-demographic data, personal and family medical history and lifestyle assessment. APPLICABILITY AND RELEVANCE The study aims to establish the foundations for the use of VCTE in children and adolescents in order to achieve early diagnosis of NAFLD. Moreover, it will serve to understand in further detail the disease and to identify the risk groups of children and adolescents who may be at risk of developing it. Ultimately, this will help determine to which subgroups of the population we need to target resources for prevention and early detection of this entity, as well as possible intervention for its treatment. TRIAL REGISTRATION The LiverKids study is registered on Clinicaltrials.gov (NCT05526274).

[PMID: 37739647 DOI: 10.1016/j.clnesp.2023.06.014] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Revised: 05/19/2023] [Accepted: 06/16/2023] [Indexed: 09/24/2023]
Abstract
BACKGROUND & AIMS Non-Alcoholic Fatty Liver Disease (NAFLD) is a global public health risk. The occurrence of adolescent NAFLD coincides with high rates of overweight and obesity, with an unhealthy lifestyle also playing a role. Data on prevalence and factors contributing to NAFLD among Asian adolescents is lacking as most studies focus on adults. This systematic review aims to determine the prevalence and factors contributing to NAFLD among adolescents. METHODS A systematic search was conducted using five (Goh et al., 2013) [5] databases: Cochrane, PubMed, Scopus, Science Direct, EBSCO and grey literature. Two reviewers independently screened studies using predefined inclusion and exclusion criteria and performed data extraction. Assessment of methodological quality was completed using the Newcastle-Ottawa checklist. RESULTS The quality of most studies were of high quality, with the majority reporting no association between lifestyle factors and NAFLD. A total of 6 studies were included in this systematic review. The prevalence of NAFLD among adolescents varied between 8.0% (Fraser et al., 2007) in a study on 5586 adolescents aged 12-19 and 16.0% (Chen et al., 2009) in another survey of 1724 adolescents aged 12-13 years old. Snacking habits and lack of physical activity had potential associations with adolescent NAFLD. Current evidence shows that lifestyle factor (Western dietary pattern) is associated with a higher risk of developing NAFLD among adolescents. CONCLUSIONS Lifestyle factors, including snacking habits and lack of physical activity, were associated with a higher risk of developing NAFLD among adolescents from high-income countries. The difference in the prevalence of NAFLD between countries with different incomes requires further investigation.

Abstract
Maternal obesity leads to obstetric complications and a high prevalence of metabolic anomalies in the offspring. Among various contributing factors for maternal obesity-evoked health sequelae, developmental programming is considered as one of the leading culprit factors for maternal obesity-associated chronic comorbidities. Although a unified theory is still lacking to systematically address multiple unfavorable postnatal health sequelae, a cadre of etiological machineries have been put forward, including lipotoxicity, inflammation, oxidative stress, autophagy/mitophagy defect, and cell death. Hereinto, autophagy and mitophagy play an essential housekeeping role in the clearance of long-lived, damaged, and unnecessary cell components to maintain and restore cellular homeostasis. Defective autophagy/mitophagy has been reported in maternal obesity and negatively impacts fetal development and postnatal health. This review will provide an update on metabolic disorders in fetal development and postnatal health issues evoked by maternal obesity and/or intrauterine overnutrition and discuss the possible contribution of autophagy/mitophagy in metabolic diseases. Moreover, relevant mechanisms and potential therapeutic strategies will be discussed in an effort to target autophagy/mitophagy and metabolic disturbances in maternal obesity.

Abstract
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is a highly prevalent comorbidity in adult patients with psoriasis, but there is a paucity of data on NAFLD in paediatric patients with psoriasis. AIM To estimate the prevalence of NAFLD in children and adolescents with psoriasis compared with age- and sex-matched healthy controls (HCs) and to evaluate risk factors for NAFLD in paediatric psoriasis. METHODS This was a cross-sectional study performed from July 2019 to December 2020 in a single tertiary care centre, which enrolled 52 children/adolescents aged 2-18 years diagnosed with psoriasis at least 6 months previously, and 52 HCs matched for age and sex. Anthropometric, metabolic and radiological assessment was performed for all participants. NAFLD prevalence was determined by liver enzyme (serum glutamic pyruvic transferase) levels, ultrasonography, shear wave elastography and aspartate aminotransferase/platelet index. Multivariate analysis was performed to determine the independent risk factors for NAFLD. RESULTS The frequency of NAFLD was found to be 28·8% in patients with paediatric psoriasis compared with 3·8% in HCs. Logistic regression showed that greater disease severity (Psoriasis Area and Severity Index ≥ 10), obesity and decreased high-density lipoprotein cholesterol (HDL-C) level were independently associated with NAFLD, and thus can be considered risk factors for NAFLD. CONCLUSION Patients with paediatric psoriasis have a higher prevalence of NAFLD compared with HCs. Children who are obese or have moderate to severe psoriasis or decreased HDL-C levels are at a higher risk of developing NAFLD.

Li R, Zhan W, Ren J, Gao X, Huang X, Ma Y. Associations between organophosphate esters concentrations and markers of liver function in US adolescents aged 12-19 years: A mixture analysis. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2022; 314:120255. [PMID: 36155224 DOI: 10.1016/j.envpol.2022.120255] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 08/31/2022] [Accepted: 09/19/2022] [Indexed: 06/16/2023]
Abstract
Liver disease has become a growing health burden, and little is known about the impairment of liver function caused by exposure to organophosphate esters (OPEs) in adolescents aged 12-19 years in the United States. To investigate the relationship between urinary metabolites of OPEs including diphenyl phosphate (DPHP), bis(1,3-dichloro-2-propyl) phosphate (BDCPP), bis(1-chloroethyl) phosphate (BCPP), bis(2-chloroethyl) phosphate (BCEP), and dibutyl phosphate (DBUP) and liver function in US adolescents aged 12-19 years. Liver function tests (LFTs) include aspartate aminotransferase (AST), albumin (ALB), alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), total bilirubin (TBIL), total protein (TP), and AST/ALT. Meanwhile, potential confounding and interaction effects were assessed. The study sample included 592 adolescents aged 12-19 from two consecutive NHANES cycles (2011-2012, 2013-2014). A composite statistical strategy combining traditional linear regression with advanced multi-pollutant models quantile based g-computation (QGC) and eXtreme Gradient Boosting (XGBoost) regression was used to analyze the joint effects of multiple OPEs on liver function indicators, and to describe the interaction between different OPEs in detail. 592 adolescent participants were 15 (14-17) years old, with similar numbers of males and females (304 vs. 288). The analysis results showed that (1) in the linear regression model, individual DPHP, BCEP exposure and ALP changes, BCEP and AST/ALT changes were positively associated. DPHP, BDCPP were negatively associated with TP changes. (2) The combined effects of various OPEs on ALB, ALT, ALP, GGT, TBIL, TP, and AST/ALT were statistically significant. (3) There is no potential interaction between different OPEs. Several OPEs and their combinations are closely related to the 8 LFT indicators. In addition, data suggest that exposure to OPEs in adolescents may be associated with liver damage. Due to limited evidence in the literature and potential limitations of the current study, our findings require more studies to confirm.

Abstract
Non-Alcoholic fatty liver disease (NAFLD) is the leading cause of chronic liver disease in children. Epigenetic alterations, such as through DNA methylation (DNAm), may link adverse childhood exposures and fatty liver and provide non-invasive methods for identifying children at high risk for NAFLD and associated metabolic dysfunction. We investigated the association between differential DNAm and liver fat content (LFC) and liver injury in pre-adolescent children. Leveraging data from the Newborn Epigenetics Study (NEST), we enrolled 90 mother-child dyads and used linear regression to identify CpG sites and differentially methylated regions (DMRs) in peripheral blood associated with LFC and alanine aminotransferase (ALT) levels in 7-12yo children. DNAm was measured using Infinium HumanMethylationEPIC BeadChips (Illumina). LFC and fibrosis were quantified by magnetic resonance imaging proton density fat fraction and elastography. Median LFC was 1.4% (range, 0.3-13.4%) and MRE was 2.5 kPa (range, 1.5-3.6kPa). Three children had LFC ≥ 5%, while six (7.6%) met our definition of NAFLD (LFC ≥ 3.7%). All children with NAFLD were obese and five were Black. LFC was associated with 88 DMRs and 106 CpGs (FDR<5%). The top two CpGs, cg25474373 and cg07264203, mapped to or near RFTN2 and PRICKLE2 genes. These two CpG sites were also significantly associated with a NAFLD diagnosis. As higher LFC associates with an adverse cardiometabolic profile already in childhood, altered DNAm may identify these children early in disease course for targeted intervention. Larger, longitudinal studies are needed to validate these findings and determine mechanistic relevance.

Oudemansiella raphanipies Polysaccharides Improve Lipid Metabolism Disorders in Murine High-Fat Diet-Induced Non-Alcoholic Fatty Liver Disease. Nutrients 2022; 14:nu14194092. [PMID: 36235744 PMCID: PMC9573705 DOI: 10.3390/nu14194092] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Revised: 09/28/2022] [Accepted: 09/28/2022] [Indexed: 11/05/2022] Open
Abstract
Oudemansiella raphanipies, also called “Edible Queen,” is a mushroom that possesses antioxidant, anti-inflammatory, anti-bacterial, anti-tumor and immunity-enhancing properties. The present study aimed to assess the effect of O. raphanipies-derived polysaccharide (ORPS) on the progression of nonalcoholic fatty liver disease (NAFLD) in mice. We studied the structure of ORPS-1 by high-performance gel permeation chromatography (HPGPC), ion chromatography-mass spectrometry (GC-MS), and Fourier transform-infrared spectroscopy (FT-IR). ORPS-1 mainly comprised galactose, fucose, glucose, mannose, and xylose, following an 18:6:6:4:1 molar ratio. In addition, the therapeutic effect as well as a potential mechanism of ORPS-1 in the treatment of high-fat diet (HFD)-induced NAFLD were investigated. The results showed that ORPS-1 improved liver function, ameliorated liver steatosis, and reduced lipid droplet accumulation in HFD mice. A metabolomics approach with GC-MS was utilized to evaluate liver improvement by ORPS-1 treatment. Principal component analysis showed that liver metabolic profiling was significantly altered by HFD feeding or treatment with an intermediate dose of ORPS-1 in mice compared with that of control mice. By investigating the metabolic pathways with identified biomarkers, various pathways such as steroid biosynthesis, valine, leucine, and isoleucine biosynthesis, glycerol phospholipid metabolism, glyceride metabolism, and arginine and proline metabolism in HFD mice were observed to be significantly influenced by ORPS-1 treatment. The results indicate ORPS-1 metabolic effects on liver tissues, provide methods for assessing the molecular impact of ORPS-1 on NAFLD, and suggest the potential mechanism underlying its health benefits.

Alterations of Central Liver Metabolism of Pediatric Patients with Non-Alcoholic Fatty Liver Disease. Int J Mol Sci 2022; 23:ijms231911072.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in children and is associated with overweight and insulin resistance (IR). Almost nothing is known about in vivo alterations of liver metabolism in NAFLD, especially in the early stages of non-alcoholic steatohepatitis (NASH). Here, we used a complex mathematical model of liver metabolism to quantify the central hepatic metabolic functions of 71 children with biopsy-proven NAFLD. For each patient, a personalized model variant was generated based on enzyme abundances determined by mass spectroscopy. Our analysis revealed statistically significant alterations in the hepatic carbohydrate, lipid, and ammonia metabolism, which increased with the degree of obesity and severity of NAFLD. Histologic features of NASH and IR displayed opposing associations with changes in carbohydrate and lipid metabolism but synergistically decreased urea synthesis in favor of the increased release of glutamine, a driver of liver fibrosis. Taken together, our study reveals already significant alterations in the NASH liver of pediatric patients, which, however, are differently modulated by the simultaneous presence of IR.

Abstract
Patients with non-advanced non-alcoholic fatty liver disease (NAFLD) have an increased cardiovascular risk. The present study was designed to evaluate the relationship between liver stiffness measurement (LSM) by transient elastography (TE) and myocardial deformation indices of all cardiac chambers in NAFLD patients without overt heart disease. All consecutive NAFLD patients diagnosed with LSM < 12.5 kPa on TE between September 2021 and December 2021 entered the study. All participants underwent blood tests, TE and two-dimensional (2D) transthoracic echocardiography (TTE) implemented with speckle-tracking echocardiography (STE) analysis of left ventricular (LV) global longitudinal strain (GLS), global circumferential strain (GCS) and global radial strain (GRS), right ventricular (RV) GLS, left atrial (LA) total global strain (TGSA) and right atrial (RA) TGSA. Main independent predictors of impaired LV-GLS (defined as absolute value less negative than - 20%) were evaluated. A total of 92 NAFLD patients (54.0 ± 11.1 years, 50% males) were prospectively analyzed. Mean LSM was 6.2 ± 2.4 kPa. Fibroscan results revealed that 76.1% of patients had F0-F1, 5.4% F2 and 18.5% F3 liver fibrosis. Despite normal biventricular systolic function on 2D-TTE, LV-GLS, LV-GCS and LV-GRS, RV-GLS, LA-TGSA and RA-TGSA were reduced in 64.1%, 38.0%, 38.0%, 31.5%, 39.1% and 41.3% of patients, respectively. Body mass index (BMI) (OR 1.76, 95% CI 1.18-2.64), neutrophil-to-lymphocyte ratio (NLR) (OR 4.93, 95% CI 1.15-31.8) and LSM (OR 9.26, 95% CI 2.24-38.3) were independently associated to impaired LV-GLS. BMI ≥ 29.3 kg/m2, NLR ≥ 1.8 and LSM ≥ 5.5 kPa were the best cut-off values for detecting outcome. LSM ≥ 5.5 kPa identifies NAFLD patients with subclinical myocardial dysfunction.

Association between alanine aminotransferase as surrogate of fatty liver disease and physical activity and sedentary time in adolescents with obesity. Eur J Pediatr 2022; 181:3119-3129.

Abstract
UNLABELLED To compare patterns of sedentary (SED) time (more sedentary, SED + vs less sedentary, SED-), moderate to vigorous physical activity (MVPA) time (more active, MVPA + vs less active, MVPA-), and combinations of behaviors (SED-/MVPA + , SED-/MVPA-, SED + /MVPA + , SED + /MVPA-) regarding nonalcoholic fatty liver diseases (NAFLD) markers. This cross-sectional study included 134 subjects (13.4 ± 2.2 years, body mass index (BMI) 98.9 ± 0.7 percentile, 48.5% females) who underwent 24-h/7-day accelerometry, anthropometric, and biochemical markers (alanine aminotransferase (ALT) as first criterion, and aspartate aminotransferase (AST), gamma-glutamyl transpeptidase (GGT), AST/ALT ratio as secondary criteria). A subgroup of 39 patients underwent magnetic resonance imaging-liver fat content (MRI-LFC). Hepatic health was better in SED- (lower ALT, GGT, and MRI-LFC (p < 0.05), higher AST/ALT (p < 0.01)) vs SED + and in MVPA + (lower ALT (p < 0.05), higher AST/ALT (p < 0.01)) vs MVPA- groups after adjustment for age, gender, and Tanner stages. SED-/MVPA + group had the best hepatic health. SED-/MVPA- group had lower ALT and GGT and higher AST/ALT (p < 0.05) in comparison with SED + /MVPA + group independently of BMI. SED time was positively associated with biochemical (high ALT, low AST/ALT ratio) and imaging (high MRI-LFC) markers independently of MVPA. MVPA time was associated with biochemical markers (low ALT, high AST/ALT) but these associations were no longer significant after adjustment for SED time. CONCLUSION Lower SED time is associated with better hepatic health independently of MVPA. Reducing SED time might be a first step in the management of pediatric obesity NAFLD when increasing MVPA is not possible. WHAT IS KNOWN • MVPA and SED times are associated with cardiometabolic risks in youths with obesity. • The relationships between NAFLD markers and concomitant MVPA and SED times have not been studied in this population. WHAT IS NEW • Low SED time is associated with healthier liver enzyme profiles and LFC independent of MVPA. • While low SED/high MVPA is the more desirable pattern, low SED/low MVPA pattern would have healthier liver enzyme profile compared with high MVPA/high SED, independent of BMI, suggesting that reducing SED time irrespective of MVPA is needed to optimize liver health.

Abstract
Epidemiological studies show that obesity during pregnancy affects more than half of the pregnancies in the developed countries and is associated with obstetric problems and poor outcomes. Obesity tends to increase the incidence of complications. Furthermore, the resulting offspring are also adversely affected. However, the molecular mechanisms of obesity leading to poor pregnancy outcomes remain unclear. Omics methods are used for genetic diagnosis and marker discovery. The aim of this review was to summarize the maternal and fetal pathophysiological alterations induced by gestational obesity,identified using multi-omics detection techniques, and to generalize the biological functions and potential mechanisms of the differentially expressed molecules.

Abstract
BACKGROUND We evaluated the relation between ALT, AST, GGT and ALP with diabetes in the Rafsanjan Cohort Study. MATERIALS AND METHODS The present study is a cross-sectional research including 9991 adults participated via sampling. We used data obtained from the Rafsanjan Cohort Study (RCS), as a part of the prospective epidemiological research studies in IrAN (PERSIAN). Elevated serum levels of ALT, AST, GGT and ALP were defined according to the reference range of the laboratory in the cohort center. Serum liver enzymes levels within the normal range were categorized into quartiles, and their relationship with diabetes was evaluated by logistic regressions. FINDINGS In present study, elevated serum levels of ALT, AST, GGT, and ALP were associated with increased odds of diabetes (adjusted ORs: 1.81, 95%CI 1.51-2.17; 1.75, 95%CI 1.32-2.32; 1.77, 95%CI 1.50-2.08; 1.60, 95%CI 1.35-1.90 respectively). Also, in subjects with normal levels of ALT, GGT and ALP, a dose-response increase was shown for diabetes. CONCLUSION Elevated levels of ALT, AST, GGT and ALP are related to a higher odds of diabetes. Also, increased levels of ALT, GGT and ALP even within normal range were independently related with the increased odds of diabetes. These results indicated the potential of elevated liver enzymes as biomarkers for the possible presence of diabetes.

Responsiveness on metabolic syndrome criteria and hepatic parameters after 12 weeks and 24 weeks of multidisciplinary intervention in overweight adolescents. J Endocrinol Invest 2022; 45:741-752. [PMID: 34780051 DOI: 10.1007/s40618-021-01699-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2021] [Accepted: 11/01/2021] [Indexed: 12/14/2022]
Abstract
PURPOSE This study aimed to evaluate the effect and individual responsiveness after 12 (12wk) and 24 weeks (24wk) of physical exercise (PE) and nutritional guidance (NG) on metabolic syndrome (MetS) criteria and hepatic parameters in overweight adolescents. METHODS The study comprised 94 overweight adolescents, aged between 10 and 16 years old, from both sexes, allocated into groups: PE and NG (PENGG, n = 64) and control with NG (NGCG, n = 30). Variables were collected at baseline, 12wk, and 24wk. Weight, height, abdominal circumference (AC), blood pressure, and peak oxygen consumption (VO2peak), as well as insulin, triglycerides (TAG), high-density lipoprotein (HDL-c), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were evaluated. HOMA-IR and QUICKI were calculated. PE session consisted of 45 min of indoor cycling, 45 min of walking, and 20 min of stretching, three times a week. The NG consisted of three collective sessions in the first 12wk. Anova, effect size, and prevalence of responders were used for statistical analysis. RESULTS The PENGG12wk reduced anthropometric and metabolic measurements, while increased VO2peak and HDL-c. The PEG24wk promoted anthropometric, blood pressure, metabolic, and VO2peak improvements, but participants without PE returned to pre-exercise status and presented worsening AST and ALT concentrations. Frequencies of respondents in PENGG12wk versus (vs) NGCG12wk were, respectively, AC (69.1% vs 17.6%, p < 0.01), HDL-c (87.2% vs 23.5%, p < 0.01), TAG (67.3% vs 41.7%, p = 0.05) and ALT (45.5% vs 5,9%; p = 0.003). CONCLUSION Interventions with PE were effective to reduce MetS components in 12wk and maintenance in 24wk, showing anthropometric, metabolic, and VO2peak improvements. Higher individual responses were observed in 12wk and in 24wk, important changes in overweight adolescent's therapy. LEVEL OF EVIDENCE Level I, evidence obtained from well-designed controlled trials randomization. TRIAL REGISTRATION NUMBER AND DATE OF REGISTRATION Brazilian Registry of Clinical Trials (RBR-4v6h7b) and date of registration April 4th, 2020.

Abstract
PURPOSE OF REVIEW To present the definitions and recommendations for movement behaviors in children and adolescents, including physical activity (PA), sedentary behaviors (SB), and sleep, and to provide an overview regarding their impact on health and obesity outcomes from childhood to adulthood, as well as interactions with appetite control. RECENT FINDINGS PA represents a variable proportion of daily energy expenditure and one can be active with high SB or vice versa. Studies have described movements across the whole day on a continuum from sleep to SB to varying intensities of PA. More PA, less SB (e.g., less screen time) and longer sleep are positively associated with indicators of physical health (e.g., lower BMI, adiposity, cardiometabolic risk) and cognitive development (e.g., motor skills, academic achievement). However, less than 10% of children currently meet recommendations for all three movement behaviors. Movement behaviors, adiposity, and related cardiometabolic diseases in childhood track into adolescence and adulthood. Furthermore, low PA/high SB profiles are associated with increased energy intake. Recent studies investigating energy balance regulation showed that desirable movement behavior profiles are associated with better appetite control and improved eating habits. Early identification of behavioral phenotypes and a comprehensive approach addressing all key behaviors that directly affect energy balance will allow for individual strategies to prevent or treat obesity and its comorbidities. Investigating exercise as a potential "corrector" of impaired appetite control offers a promising weight management approach.

Deletion of RNF186 expression suppresses diet-induced hepatic steatosis by regulating insulin activity. iScience 2022; 25:103859.

Abstract
RING finger protein186 (RNF186) is dramatically upregulated in steatotic livers. The physiological role of RNF186 in non-alcoholic fatty liver disease (NAFLD) remains obscure. Here, we found that hepatocyte-specific RNF186 knockout (RNF186LKO) mice were protected from HFD-induced obesity. RNF186 ablation in liver suppressed inflammatory responses and ER stress and alleviated insulin tolerance, leading to improved glucose and lipid metabolism under HFD conditions. RNA-seq and western blot analyses revealed a significant downregulation of peroxisome proliferator-activated receptor γ, stearoyl-CoA desaturase 1, and cluster of differentiation 36 in the liver of RNF186 knockout mice consuming HFD. RNF186 deletion in liver results in less weight gain during HFD feeding and is associated with reduced liver fat, inflammation, and improved glucose and insulin tolerance. In contrast, upregulation of RNF186 in C57BL/6J mice livers impaired lipid metabolism and insulin tolerance. The collective results suggest that RNF186 may be a potential regulator of NAFLD in obesity. RNF186 deficiency on high-fat diet alleviates liver steatosis and insulin tolerance RNF186 increased hepatic TG accumulation and impaired insulin sensitivity RNF186 ablation suppresses hepatic inflammation associated with high-fat diet RNF186 maybe a potential regulator of NAFLD in obesity

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Bark of Ficus benghalensis L. (family: Moraceae), commonly known as Banyan is recorded as Nyagrodha in Ayurvedic Pharmacopeia of India to manage burning sensation, obesity, diabetes, bleeding disorders, thirst, skin diseases, wounds, and dysmenorrhoea. However, the effect of F. benghalensis bark over glycolysis, gluconeogenesis, and appetite regulation in insulin-resistant pathogenesis has not been reported yet. AIM OF THE STUDY The present study aimed to investigate the effect of hydroalcoholic extract of F. benghalensis bark in gluconeogenesis, glycolysis, and appetite regulation in fructose-induced insulin resistance in experimental rats. MATERIALS AND METHODS Male Wister rats were supplemented with fructose in drinking water (10% w/v for 42 days and 20% w/v for next 12 days; a total of 54 days); insulin resistance was confirmed via the elevated area under the curve of the glucose during oral glucose tolerance test after 54 days and was subjected with extract treatment for next 30 days. After 30 days of treatment, animals were fasted to perform oral glucose and insulin tolerance test to estimate glucose and insulin levels. The blood sample was collected for biochemical estimation and the liver homogenate was prepared to estimate hepatic enzymes and enzymatic and non-enzymatic anti-oxidant biomarkers followed by histopathological evaluation. Also, glycogen content was quantified in gastrocnemius muscle and liver homogenates. Further, reported bioactives from the F. benghalensis were retrieved from the ChEBI database and docked against hexokinase, phosphofructokinase, glucose-6-phosphatase, lactate dehydrogenase, and fructose-1,6-biphosphatase to identify the probable lead hits against the enzymes involved in gluconeogenesis. RESULTS Treatment with the F. benghalensis bark extract significantly increased the body weight and food intake and significantly decreased fructose supplemented water intake. Further, treatment with extract significantly increased the exogenous glucose clearance and well responded to the exogenous insulin. Further, extract treatment improved lipid metabolism, ameliorated plasma leptin, and multiple enzymatic and non-enzymatic antioxidant biomarkers. Likewise, it also improved gluconeogenesis mediated pathogenesis of non-alcoholic fatty liver injury. Additionally, molecular docking also identified mucusisoflavone A and B as lead hits in downregulating gluconeogenesis. CONCLUSION Hydroalcoholic extract of F. benghalensis bark may prevent insulin resistance by downregulating gluconeogenesis and improving the appetite in fructose-induced insulin-resistant rats.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is considered as one of the most common causes of chronic liver disease. It includes a group of conditions associated with fat deposition in liver cells. Also, NAFLD is strongly associated with obesity and insulin resistance (IR). Until now, there is no pharmacological treatment validated for this disease. Fasting, nutritional intervention, and weight loss can be considered the first line in treating hepatic steatosis. This review is based on the scientific evidence showing the results of these interventions in the past years. The results include fasting and nutritional support for NAFLD treatment in humans. In clinical trials and cohort studies, an increase in hepatic fat content was correlated with a weight loss of at least 7% and a diet resembling the Mediterranean diet (MD) improving hepatic biomarkers and histological regression of NAFLD. Fasting is a dietary approach known to improve the lipid profile in healthy and obese populations by decreasing overall cholesterol, triglycerides, LDL, and increasing HDL. Bariatric surgery helps improve liver fat content in patients with serious health problems due to overweight.

Abstract
Data on the association between dietary red meat intake and non-alcoholic fatty liver disease (NAFLD) are limited. We designed this case-control study to determine the association between red and processed meat consumption and risk of NAFLD in Iranian adults. A total of 999 eligible subjects, including 196 NAFLD patients and 803 non-NAFLD controls were recruited from hepatology clinics in Tehran, Iran. A reliable and validated food frequency questionnaire was used to evaluate the red and processed meat intakes. The analyzes performed showed that in an age- and gender-adjusted model, patients with the highest quartile of red meat intake had an approximately three-fold higher risk of NAFLD than those with the lowest quartile of intake (odds ratio [OR], 3.42; 95% confidence interval [CI], 2.16–5.43; p value < 0.001). Moreover, patients in the highest quartile of processed meat intake had a 3.28 times higher risk of NAFLD, compared to the lowest quartile(OR, 3.28; 95% CI, 1.97–5.46; p value < 0.001).Both these associations remained significant by implementing additional adjustments for body mass index, energy intake, dietary factors, diabetes, smoking, and physical activity (OR, 3.65; 95% CI, 1.85–7.18; p value < 0.001 and OR, 3.25; 95% CI, 1.57–6.73; p value = 0.002, respectively).Our findings indicate that both red and processed meat intakes are related to the increased odds of NAFLD; however, prospective studies are needed to confirm these results.

Abstract
It has been suggested that small intestinal bacterial overgrowth (SIBO) could cause nonalcoholic fatty liver disease (NAFLD), but this association was not examined in children by meta-analysis. This meta-analysis aimed to determine the association between SIBO and NAFLD in children. The electronic databases PubMed, Embase, and Cochrane Library were searched for studies published before April 22, 2021. The outcome was the association between SIBO and NAFLD. Three studies and 205 children were included. All three studies reported the association between SIBO and NAFLD. Children with SIBO were more likely to have NAFLD (odds ratio = 5.27, 95% confidence interval (CI): 1.66-16.68, P<0.001; I2 = 63.5%, Pheterogeneity = 0.065). When directly pooling the reported relative risks (RR) from two studies, children with NAFLD had an over 2-fold increased relative risk of developing SIBO (RR = 2.17, 05%CI: 1.66-2.82, P<0.001; I2 = 0.0%, Pheterogeneity = 0.837). This meta-analysis reports a possible association between SIBO and NAFLD in children.

Abstract
BACKGROUND Children born to mothers with obesity are at increased risk of obesity. Influences underlying this predisposition include in-utero exposures, genetic predisposition and a shared family environment. Effective intervention strategies are needed to prevent obesity in these high-risk children; this requires evaluation of modifiable pregnancy and early-life risk factors. OBJECTIVES To assess the individual and cumulative contributions of maternal and early-life modifiable exposures on childhood adiposity and obesity outcomes in 3-year-old children born to women with obesity. METHODS We used adjusted regression to assess the individual and cumulative contributions of six exposures (early pregnancy BMI, excessive gestational weight gain, mode of infant feeding and three measures of childhood eating habits [food responsiveness, slowness in eating and a processed/snacking dietary pattern score]) on body composition in 495 three-year-old children. Outcomes included BMI z-score, arm circumference and overweight/obesity (BMI≥25.0 kg/m2 ). RESULTS While the UPBEAT intervention did not influence adiposity outcomes in 3-year-old children, the six modifiable exposures combined incrementally to increase childhood adiposity and obesity. For each additional exposure, children had a higher BMI z-score (β = 0.35SD [95% confidence interval: 0.23, 0.47]), arm circumference (β = 0.59 cm [0.40, 0.79]) and risk of overweight/obesity (relative risk 1.49 [1.26, 1.77]). Compared to no exposures, children with four or more exposures had a higher BMI z-score (1.11SD [0.65, 1.58]), arm circumference (2.15 cm [1.41, 2.89]) and risk of overweight/obesity (3.01 [1.67, 5.41]) (all P < 0.001). CONCLUSION Our findings suggest that complex interventions targeting preconception, pregnancy, perinatal and early childhood exposures offer a potential strategy for prevention of pre-school obesity.

Abstract
In this study, we investigated the anti-obesity properties of the novel peptide Ala-Gly-Leu-Gln-Phe-Pro-Val-Gly-Arg (AGL9), isolated from the enzymatic hydrolysate of Allomyrinadichotoma larvae. To investigate the preventive effects of AGL9 against hepatic steatosis and its possible mechanisms of action, we established an nonalcoholic fatty liver disease (NAFLD) model by feeding C57BL/6 mice a high-fat diet. NAFLD mice were administered 100 mg/kg AGL9 and 60 mg/kg orlistat via gavage (10 mL/kg) for 5 weeks, followed by the collection of blood and liver tissues. We found that AGL9 normalized the levels of serum alanine aminotransferase, aspartate aminotransferase, triglyceride, total cholesterol, high-density lipoprotein, very low-density lipoprotein (LDL)/LDL, adiponectin, and leptin in these mice. Additionally, AGL9 activated the protein-level expression of 5′ AMP-activated protein kinase and acetyl-CoA carboxylase phosphorylation and the transcript-level expression of sterol regulatory element-binding protein-1c, fatty acid synthase, superoxide dismutase, glutathione peroxidase, glucocorticoid receptor, nuclear respiratory factor 2, tumor necrosis factor-α, interleukin-1β, interleukin-6, and monocyte chemoattractant protein-1 in hepatocytes. These results showed that AGL9 exhibited hepatoprotective effects by attenuating lipid deposition, oxidative stress, and inflammation via inhibition of AMPK/Nrf2 signaling, thereby reducing the production of hepatic proinflammatory mediators and indicating AGL9 as a potential therapeutic strategy for NAFLD.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is one of the most common liver diseases, which is often accompanied by mitochondrial dysfunction. Cardiolipin is a special lipid of mitochondrial inner membrane and any change of cardiolipin may cause series of mitochondria-relevant diseases. Changes in cardiolipin content, fatty acid side chain composition after cardiolipin remodeling, and the content of cardiolipin remodeling enzymes play an important role in the occurrence and development of NAFLD-related mitochondrial dysfunction.

[PMID: 34207346 PMCID: PMC8235074 DOI: 10.3390/biom11060911] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2021] [Revised: 06/15/2021] [Accepted: 06/15/2021] [Indexed: 12/26/2022] Open
Abstract
BACKGROUND Underage drinking is associated with health risk behaviors. Serum keratin-18 (CK18) levels are increased in liver diseases and may be biomarkers of outcome. The purpose of this study was to determine if the total CK18 (M65) or caspase-cleaved CK18 (M30) levels were different in adolescents admitted to hospital because of alcohol intoxication and controls with excluded liver diseases. METHODS A prospective study included 57 adolescents after alcohol use and 23 control subjects. The concentrations of M30 and M65 in the serum samples were evaluated using an enzyme-linked immunosorbent assay. RESULTS The median age was 15 (14-17) years and 49% were male. There were significant differences in M65 levels between the study and control groups (p = 0.03). The concentrations of M30 and M65 were insignificant in adolescents divided into subgroups according to blood alcohol concentrations (BAC). Significant positive correlations were found between BAC and M65 levels (p = 0.038; r = 0.3). In receiver operating characteristic (ROC) analysis M65 (cut-off = 125.966 IU/l, Se = 70.2%, Sp = 43.5%) allowed to differentiate between patients with and without alcohol intoxication (AUC = 0.66, p = 0.03). CONCLUSION M65 appears to be a promising non-invasive biomarker of hepatocyte injury during alcohol intoxication in adolescents. Moreover, a higher concentration of M65 may indicate early organ injury before the increase in the activity of liver enzymes, alanine aminotransferase (ALT) and aspartate aminotransferase (AST).

Abstract
Association between pulmonary function tests (PFTs) and non-alcoholic fatty liver disease (NAFLD) has been reported in adult studies; however, there is lack of pediatric studies. Our study aimed to evaluate PFTs in children with NAFLD. A total of 137 children with NAFLD and 100 healthy children of matched age and sex were included in the study. Different PFTs including forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), FEV1/FVC ratio, residual volume (RV), and total lung capacity (TLC) were performed for all included children. Lipid profile, insulin resistance, fasting and postprandial glucose level, and high sensitive C reactive protein (hs-CRP) were measured. FEV1 %, FVC %, FEV1/FVC ratio, RV, and TLC were significantly lower in the patient group compared with the control group (P < 0.05), while RV and hs-CRP were significantly higher in children with NAFLD. Restrictive lung dysfunction was the commonest pulmonary dysfunction detected in children with NAFLD (21.9%). PFT indices were significantly correlated with grade and duration of NAFLD, insulin resistance, waist circumference, and hs-CRP. Regression analysis revealed that insulin resistance and hs-CRP were independently associated with decreased PFT indices.Conclusion: PFT indices were impaired in children with NAFLD and this impairment was independently associated with insulin resistance and hs-CRP. What is Known: • Pulmonary function tests (PFTs) abnormalities are common in adults with nonalcoholic fatty liver disease (NAFLD). • Studies involving PFTs abnormalities in pediatric NAFLD are lacking. What is New: • It is the first study that assessed PFT in pediatric patients with NAFLD. • PFTs abnormalities are present in children with NAFLD. • Insulin resistance and high sensitive C reactive protein are independently associated with the decline of PFTs in children with NAFLD.

Abstract
INTRODUCTION Obesity is associated with nonalcoholic fatty liver disease (NAFLD) in children. Our aim was to analyze the association of dietary and sociodemographic factors with NAFLD in obese children and adolescents. MATERIALS AND METHODS Thirty-three obese patients from 6-16 years of age were included in the present analytic cross-sectional study. Obesity was diagnosed with a body mass index z-score > 2 SD. NAFLD was estimated by liver ultrasound, serum amino transferases, and elastography. The sociodemographic variables were evaluated using validated questionnaires. Diet was estimated through two 24-h recall dietary surveys focused on the quantity of food energy, simple sugars, polyunsaturated fatty acids (PUFAs), and antioxidants. RESULTS Hepatic steatosis was identified by abdominal ultrasound in 13 patients (39.4%) and the serum alanine aminotransferase level was above the upper reference value in 54.2%. A higher educational level in both parents, greater monthly food expenditure, and a higher socioeconomic level were associated with NAFLD. Overall, simple sugar and saturated fat consumption was above the recommended daily intake, whereas vitamin E and PUFA consumption was below those parameters. CONCLUSIONS NAFLD was identified in one-third of the cases. There was an association between NAFLD and sociodemographic variables. Both groups had an increased intake of simple sugars and a reduced intake of PUFAs. The selective occurrence of NAFLD could be related to a genetic predisposition that has been demonstrated in a Mexican population.

Abstract
Non-alcoholic fatty liver disease and alcoholic liver disease, the two most prevalent liver diseases worldwide, share a common pathology but have largely been considered disparate diseases. Liver diseases are widely underestimated, but their prevalence is increasing worldwide. The Western diet (high-fat, high-sugar) and binge drinking (rapid consumption of alcohol in a short period of time) are two highly prevalent features of standard life in the United States, and both are linked to the development and progression of liver disease. Yet, few studies have been conducted to elucidate their potential interactions. Data shows binge drinking is on the rise in several age groups, and poor dietary trends continue to be prevalent. This review serves to summarize the sparse findings on the hepatic consequences of the combination of binge drinking and consuming a Western diet, while also drawing conclusions on potential future impacts. The data suggest the potential for a looming liver disease epidemic, indicating that more research on its progression as well as its prevention is needed on this critical topic.

Abstract
BACKGROUND Epidemiological evidence for the association of soft drink consumption with nonalcoholic fatty liver disease (NAFLD) is inconsistent, and such association has not been prospectively examined in the general adult population. OBJECTIVES We aimed to investigate the prospective association between soft drink consumption and the risk of NAFLD in a Chinese adult population. METHODS This prospective cohort study investigated 14,845 participants [mean age: 39.3 y; 6203 (41.8%) men] who were free of liver disease, cardiovascular disease, and cancer at baseline. Soft drink consumption (mainly sugar-containing carbonated beverages) was measured at baseline using a validated FFQ. NAFLD was diagnosed based on abdominal ultrasound without significant alcohol consumption and other causes of liver disease. Hepatic steatosis index (HSI) was calculated based on sex, BMI, and blood transaminase levels. Cox proportional hazards regression models were used to examine the association of soft drink consumption with incident NAFLD. RESULTS A total of 2888 first-incident cases of NAFLD occurred during 42,048 person-years of follow-up (median follow-up: 4.2 y). After adjusting for demographic characteristics, lifestyle factors, dietary intake, and inflammatory markers, the multivariable HRs (95% CIs) for incident NAFLD were 1.00 (reference) for <1 serving/wk, 1.18 (1.03, 1.34) for 1 serving/wk, 1.23 (1.08, 1.40) for 2-3 servings/wk, and 1.47 (1.25, 1.73) for ≥4 servings/wk, respectively (P for trend < 0.0001). Further sensitivity analysis showed that the corresponding multivariable HRs (95% CIs) for incident HSI-defined NAFLD were 1.00 (reference), 0.96 (0.70, 1.31), 1.16 (0.83, 1.62), and 1.59 (1.07, 2.37), respectively (P for trend < 0.0001). CONCLUSIONS The results from our prospective study indicate that soft drink consumption is associated with an increased risk of NAFLD in Chinese adults. This study was registered at UMIN Clinical Trials Registry as UMIN000027174.

Abstract
Non-alcoholic fatty liver disease is the accumulation of triglycerides in liver. In its malignant form, it can proceed to steatohepatitis, fibrosis, cirrhosis, cancer and ultimately liver impairment, leading to liver transplantation. In a previous study, ultrasound-induced thermal strain imaging (US-TSI) was used to distinguish between excised fatty livers from obese mice and non-fatty livers from control mice. In this study, US-TSI was used to quantify lipid composition of fatty livers in ob/ob mice (n = 28) at various steatosis stages. A strong correlation coefficient was observed (R2 = 0.85) between lipid composition measured with US-TSI and hepatic triglyceride content. Hepatic triglyceride content is used to quantify adipose tissue in liver. The ob/ob mice were divided into three groups based on the degree of steatosis that is used in clinics: none, mild and moderate. A non-parametric Kruskal-Wallis test was conducted to determine if US-TSI can potentially differentiate among the steatosis grades in non-alcoholic fatty liver disease.

Abstract
OBJECTIVES To detect early left ventricular dysfunction in children with non-alcoholic fatty liver disease using three-dimensional speckle tracking echocardiography. METHODS Forty obese children with non-alcoholic fatty liver disease were included as group I. Another 40 obese children without non-alcoholic fatty liver disease of matched age, sex, and weight were included as group II. Forty healthy controls of matched age and sex served as a control group. Anthropometric measurements, laboratory investigations, and echocardiographic examinations including three-dimensional speckle tracking echocardiography were measured for all included children. RESULTS Abnormal lipid profile was detected in children with non-alcoholic fatty liver disease. Troponin I levels were significantly higher in children with non-alcoholic fatty liver disease compared to obese children without non-alcoholic fatty liver disease and to healthy controls. Three-dimensional speckle tracking echocardiography examination revealed a significant reduction of left ventricular global longitudinal strain, circumferential strain, radial strain, and area strain in children with non-alcoholic fatty liver disease inspite of normal left ventricular fraction shortening measured by conventional echocardiography. All strains were negatively correlated with the grade of non-alcoholic fatty liver disease. CONCLUSION Non-alcoholic fatty liver disease is associated with subclinical left ventricular dysfunction. Three-dimensional speckle tracking echocardiography can be helpful in identifying early left ventricular dysfunction in children with non-alcoholic fatty liver disease even in the presence of normal left ventricular ejection fraction.

Abstract
PURPOSE Non-alcoholic fatty liver disease (NAFLD) is increasingly being recognized in the pediatric population, therefore, the search for non-invasive parameters to predict progression of NAFLD is of great interest. The aim of this study was to assess serum concentration of sCD36 in children with obesity and to determine its diagnostic value in pediatric NAFLD. PATIENTS AND METHODS The study group consisted of 50 children with obesity aged 8-17.5 years, admitted to our Department because of suspected liver pathology. Selected liver diseases were excluded in the examined group. Anthropometry, laboratory tests (including the concentration of sCD36) and liver ultrasound, were performed in all subjects. RESULTS NAFLD was confirmed in 16 out of 50 patients with obesity. There was significantly higher activity of ALT, AST, GGT, and increased waist-hip ratio WHR in individuals with NAFLD in comparison to non-hepatopathic children with obesity. We did not find a significant difference between sCD36 concentration in patients with obesity and NAFLD and non-hepathopathic patients with obesity. We also did not find a significant difference between sCD36 concentration in children with obesity in comparison to the control group and between mild (grade 1) vs. advanced (grade ≥2) steatosis. Correlation of sCD36 concentration with anthropometric, biochemical, and bioimpedance parameters in children with obesity was confirmed only with body fat percentage. CONCLUSIONS sCD36 is not a suitable parameter to differentiate children with NAFLD from non-hepatopathic children with obesity and controls without obesity. Further studies on a larger pediatric population are needed to confirm these findings.

Abstract
Rosmarinic acid (RA) is a water-soluble phenolic compound extracted from Boraginaceae and Lamiaceae. This study was designed to investigate the role and mechanism of action of RA in improving nonalcoholic fatty liver disease (NAFLD). Male SD rats maintained on a high fat diet and L02 cells stimulated with oleic acid were treated with RA. Our results showed that RA significantly reduced total cholesterol, triglycerides, low-density lipoprotein cholesterol, alanine aminotransferase, aspartate aminotransferase, and malondialdehyde levels and increased high-density lipoprotein cholesterol, superoxide dismutase and adenosine triphosphate levels both in vivo and in vitro. Hematoxylin and eosin staining and oil red O staining showed that RA had a good lipid-lowering effect and substantial protective effects on liver injury. Transmission electron microscopy and JC-1 fluorescence results showed that RA could improve mitochondrial damage in hepatocytes. Additionally, flow cytometry results indicated that RA inhibited ROS generation and apoptosis in L02 cells. The impaired hepatocytes were restored by using RA in NAFLD models characterized by down-regulating YAP1 and TAZ, meanwhile up-regulating PPARγ and PGC-1α. When YAP1 was over-expressed, RA reduced the expression of YAP1; however, the action of RA was significantly blocked by silencing YAP1. The experimental results indicated that RA markedly alleviated NAFLD by repairing mitochondrial damage and regulating the YAP1/TAZ-PPARγ/PGC-1α signaling pathway.

[PMID: 33515562 DOI: 10.1016/j.lfs.2021.119071] [Citation(s) in RCA: 25] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2020] [Revised: 10/14/2020] [Accepted: 01/12/2021] [Indexed: 02/07/2023]
Abstract
BACKGROUND Non-alcoholic fatty liver disease (NAFLD) has a high incidence and mortality rate, and a rapid course of clinical development. Although miR-125b is closely associated with the pathogenesis of liver fibrosis and hepatocellular carcinoma, the role of miR-125b in NAFLD remains unknown. METHODS The levels of TNF-α, IL-6, and IL-1β expression were examined via ELISA assays. Real-time PCR was used to determine the levels of miR-125b and tumor necrosis factor alpha-induced protein 3 (TNFAIP3) expression. The related molecular mechanisms were examined by performing luciferase reporter, western blot, and immunofluorescence assays. Structural changes in the livers of mice with NAFLD were observed via H&E staining. RESULTS The levels of TNF-α, IL-6, and IL-1β in NAFLD patients were greatly increased, and miR-125b expression was significantly up-regulated. The phosphorylation of IκBα and p65, and secretion of inflammatory factors were all markedly decreased by miR-125b silencing, but greatly increased by miR-125b overexpression. We also demonstrated that downregulation of TNFAIP3 in NAFLD was negatively correlated with miR-125b. Interestingly, the influence of miR-125b inhibitors on nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB)-mediated inflammatory responses were greatly aggravated by co-treatment with TNFAIP siRNA; however, the opposite results were obtained after treatment with miR-125b mimics and TNFAIP plasmids. Furthermore, the HF-induced liver damage and inflammatory responses were greatly ameliorated by miR-125b inhibitors but further aggravated by co-treatment with TNFAIP3 siRNA. CONCLUSION MiR-125b promoted the NF-κB-mediated inflammatory response in NAFLD by directly targeting TNFAIP3, and that mechanism might be target for treating NAFLD.

Abstract
BACKGROUND Nonalcoholic fatty liver disease is a common reason for chronic liver disease in children and adults. The increasing incidence of the disease has become one of the most critical public health problems in the 21st century, closely related to genetic and environmental factors. So far, apart from changing lifestyle and diet, modern medicine still lacks effective treatment measures. Chinese patent medicine has the advantages of apparent curative effect, overall regulation and fewer side effects. However, there is a lack of research on the simultaneous comparison of various Chinese patent medicines. Therefore, we used a reticular meta-analysis to indirectly compare the efficacy and safety of different oral Chinese patent medicines through standard reference. METHOD We will conduct a comprehensive and systematic search of Chinese and English databases from the beginning to December 2020. All randomized controlled trials (RCTs) of oral Chinese patent medicine for NAFLD in children will be searched. The 2 researchers then independently filter the retrieved literature, extract the data according to the data extraction table and assess the risk of bias. We will perform a pair of meta-analyses and a Bayesian network meta-analysis. STATA and Win BUGS software will be used for data analysis. RESULTS This study will thoroughly compare and analyze the differences in the efficacy of all kinds of TCPM in NAFLD treatment in childhood or adolescence. CONCLUSION This study will provide reference and evidence support for clinical drug selection optimization. ETHICS AND DISSEMINATION This study does not require ethical approval.

Abstract
Nonalcoholic fatty liver disease (NAFLD) affects up to 70% of children with obesity and has become the number one etiology for liver transplant in the United States. Early, effective intervention is critical to prevent disease progression into adulthood. Yet, it is seldom achieved through lifestyle modification alone. Thus, children must be included in NAFLD pharmacology trials, which, to date, continue to focus primarily on adult populations. This commentary serves as a call to action.

Abstract
Dual specificity phosphatases (DUSPs) play a crucial role in the regulation of intracellular signalling pathways, which in turn influence a broad range of physiological processes. DUSP malfunction is increasingly observed in a broad range of human diseases due to deregulation of key pathways, most notably the MAP kinase (MAPK) cascades. Dual specificity phosphatase 26 (DUSP26) is an atypical DUSP with a range of physiological substrates including the MAPKs. The residues that govern DUSP26 substrate specificity are yet to be determined; however, recent evidence suggests that interactions with a binding partner may be required for DUSP26 catalytic activity. DUSP26 is heavily implicated in cancer where, akin to other DUSPs, it displays both tumour-suppressive and -promoting properties, depending on the context. Here we review DUSP26 by evaluating its transcriptional patterns, protein crystallographic structure and substrate binding, as well as its physiological role(s) and binding partners, its role in human disease and the development of DUSP26 inhibitors.

Abstract
INTRODUCTION Non-alcoholic fatty liver disease (NAFLD) affects ~25% of world population and cases have increased in recent decades. These anomalies have several etiologies; however, obesity and metabolic dysfunctions are the most relevant causes. Despite being considered a public health problem, no effective therapeutic approach to treat NAFLD is available. For that, a deep understanding of metabolic routes that support hepatic diseases is needed. AREAS COVERED This review covers aspects of the onset of NAFLD. Thereby, biochemistry routes as well as cellular and metabolic effects of the gut microbiota in body's homeostasis and epigenetics are contextualized. EXPERT OPINION Recently, the development of biological sciences has generated innovative knowledge, bringing new insights and perspectives to clarify the systems biology of liver diseases. A detailed comprehension of epigenetics mechanisms will offer possibilities to develop new therapeutic and diagnostic strategies for NAFLD. Different epigenetic processes have been reported that are modulated by the environment such as gut microbiota, suggesting strong interplays between cellular behavior and pathology. Thus, a more complete description of such mechanisms in hepatic diseases will help to clarify how to control the establishment of fatty liver, and precisely describe molecular interplays that potentially control NAFLD.

Abstract
Obesity is the single greatest risk factor for nonalcoholic fatty liver disease (NAFLD). Without intervention, most pediatric patients with NAFLD continue to gain excessive weight, making early, effective weight loss intervention key for disease treatment and prevention of NAFLD progression. Unfortunately, outside of a closely monitored research setting, which is not representative of the real world, lifestyle modification success for weight loss in children is low. Bariatric surgery, though effective, is invasive and can worsen NAFLD postoperatively. Thus, there is an evolving and underutilized role for pharmacotherapy in children, both for weight reduction and NAFLD management. In this perspective article, we provide an overview of the efficacy of weight reduction on pediatric NAFLD treatment, discuss the pros and cons of currently approved pharmacotherapy options, as well as drugs commonly used off-label for weight reduction in children and adolescents. We also highlight gaps in, and opportunities for, streamlining obesity trials to include NAFLD assessment as a valuable, secondary, therapeutic outcome measure, which may aid drug repurposing. Finally, we describe the already available, and emerging, minimally-invasive biomarkers of NAFLD that could offer a safe and convenient alternative to liver biopsy in pediatric obesity and NAFLD trials.

Abstract
Obesity has become a worldwide health concern among the pediatric population. The prevalence of non-alcoholic fatty liver disease (NAFLD) is growing rapidly, alongside the high prevalence of obesity. NAFLD refers to a multifactorial disorder that includes simple steatosis to non-alcoholic steatohepatitis (NASH) with or devoid of fibrosis. NAFLD is regarded as a systemic disorder that influences glucose, lipid, and energy metabolism with hepatic manifestations. A sedentary lifestyle and poor choice of food remain the major contributors to the disease. Prompt and timely diagnosis of NAFLD among overweight children is crucial to prevent the progression of the condition. Yet, there has been no approved pharmacological treatment for NAFLD in adults or children. As indicated by clinical evidence, lifestyle modification plays a vital role as a primary form of therapy for managing and treating NAFLD. Emphasis is on the significance of caloric restriction, particularly macronutrients (fats, carbohydrates, and proteins) in altering the disease consequences. A growing number of studies are now focusing on establishing a link between vitamins and NAFLD. Different types of vitamin supplements have been shown to be effective in treating NAFLD. In this review, we elaborate on the potential role of vitamin E with a high content of tocotrienol as a therapeutic alternative in treating NAFLD in obese children.

Abstract
BACKGROUND AND OBJECTIVES In 2007, the American Academy of Pediatrics recommended that children with obesity should be screened for nonalcoholic fatty liver disease (NAFLD). Population epidemiology reveals that NAFLD is common in children; however, little is known about rates of clinical diagnosis. In this study, we aim to determine screening practices, annual incidence, and clinical characteristics of NAFLD in children within an integrated community health system. METHODS Using electronic health records, we identified patients newly diagnosed (aged 5-18) with NAFLD on the basis of diagnostic codes from the 9th and 10th revisions of the International Classification of Diseases. We calculated screening rates and annual incidence rates of NAFLD from January 1, 2009, to December 31, 2018. RESULTS In this study, we evaluated 7 884 844 patient-years. Screening was performed in 54.0% of children with obesity and 24.0% of children with overweight. The results revealed 36 658 children aged 9 to 18 with overweight or obesity and alanine aminotransferase >30 U/L. Of these children, 12.3% received further workup for NAFLD. The incidence of an NAFLD diagnosis significantly increased over time, with 36.0 per 100 000 in 2009 and 58.2 per 100 000 in 2018 (P < .0001). CONCLUSIONS Our study of a large integrated health care system in southern California revealed that the incidence of NAFLD in children is increasing, although many children may remain undiagnosed.

Abstract
OBJECTIVE Potent glucocorticoids (GC) cause iatrogenic Cushing’s syndrome (ICS) due to suppression of hypothalamo-pituitary-adrenal (HPA) axis and may progress to adrenal insufficiency (AI). The aim was to review the clinical and laboratory findings of patients with ICS and to investigate other serious side effects. METHODS The possibility of AI was investigated by low-dose adrenocorticotrophic hormone test. Hydrocortisone was started in patients with adrenal failure. RESULTS Fourteen patients (five boys) with ages ranging from 0.19 to 11.89 years were included. The duration of GC exposure ranged from 1 to 72 months. Ten patients were prescribed topical GC and the rest had oral exposure. Moon face and abdominal obesity were detected in all patients. At presentation, 12 of 14 had AI and two infants had hypercalcemia and nephrocalcinosis. Of 11 patients, ultrasonography revealed hepatosteatosis in five. A cream for diaper dermatitis was used in one infant and the active ingredient was listed as panthenol. However, blood and urine steroid analyses revealed that all endogenous steroids were suppressed. Median (range) time to normalization of HPA axis function was 60 (30-780) days. CONCLUSION The majority (85%) of patients had life-threatening AI and two patients had hypercalcemia. These results highlight the serious side-effects of inappropriate use of potent GCs, especially in infants. The recovery of the HPA axis in children might take as long as three years. Parents should be informed regarding the possibility of some products containing unlisted synthetic GC and to be aware of their side effects.

Abstract
Objective To use network pharmacology and molecular docking technology in predicting the main active ingredients and targets of Qushi Huayu Decoction (QHD) treatment in Nonalcoholic Fatty Liver Disease (NAFLD) and explore the potential mechanisms of its multi-component-multi-target-multi-pathway. Materials and Methods The main chemical components of QHD were searched using traditional Chinese medicine system pharmacology technology platform (TCMSP) and PubChem database. The main chemical components of the prescription were ADMET screened by the ACD/Labs software. The main active ingredient was screened by 60% oral bioavailability, and 60% of “bad” ingredients were removed from the drug-like group. Swiss Target Prediction, the SEA, and HitPick systems were sequentially used to search for the target of each active ingredient, and a network map of the QHD's target of the active ingredient was constructed. Genome annotation database platforms (GeneCards, OMIM, and DisGeNET) were used to predict action targets related to fatty liver disease. “Drug-Disease-Target” network diagram could be visualized with the help of Cytoscape (3.7.1) software. UniProt and STRING database platforms were used to build a protein interaction network. The KEGG signal pathway and DAVID platform were analyzed for biological process enrichment. Results A total of 128 active ingredients and 275 corresponding targets in QHD were discovered through screening. 55 key target targets and 27 important signaling pathways were screened, such as the cancer pathway, P13K-AKT signaling pathway, PPAR signaling pathway, and other related signaling pathways. Conclusions The present study revealed the material basis of QHD and discussed the pharmacological mechanism of QHD in fatty liver, thus providing a scientific basis for the clinical application and experimental research of QHD in the future.

Abstract
Objectives As rates of obesity around the world have increased, so has the detection of high level of liver fat in children and adolescents. This may put them at risk for cardiovascular disease later in life. This analysis of a cross‐sectional population‐based study of children and adolescents evaluated demographic and lifestyle determinants of percent liver fat. Methods Healthy participants (123 girls and 99 boys aged 5–17 years) recruited by convenience sampling in three locations completed questionnaires, anthropometric measurements, and dual X‐ray absorptiometry and magnetic resonance imaging (MRI) assessment. General linear models were applied to estimate the association of demographic, anthropometric, and dietary factors as well as physical activity with MRI‐based percent liver fat. Results The strongest predictor of liver fat was body mass index (BMI; p < 0.0001); overweight and obesity were associated with 0.5% and 1% higher liver fat levels. The respective adjusted mean percent values were 2.9 (95% CI 2.7, 3.1) and 3.4 (95% CI 3.2, 3.6) as compared to normal weight (2.4; 95% CI 2.3, 2.6). Mean percent liver fat was highest in Whites and African Americans, intermediate in Hispanic, and lowest among Asians and Native Hawaiians/Pacific Islanders (p < 0.0001). Age (p = 0.67), sex (p = 0.28), physical activity (p = 0.74), and diet quality (p = 0.70) were not significantly related with liver fat. Conclusions This study in multiethnic children and adolescents confirms the strong relationship of BMI with percent liver fat even in a population with low liver fat levels without detecting an association with age, sex, and dietary or physical activity patterns.

Abstract
OBJECTIVES Nonalcoholic fatty disease (NAFLD) affects 3-10% of the pediatric population, making it the most common chronic liver disease among children. The aim of the study is to identify potential biomarkers enabling the diagnosis of NAFLD and monitoring the course of the disease. METHODS Proteome analysis was performed in a group of 30 patients (19 boys and 11 girls) in total, of whom 16 children had previously diagnosed NAFLD based on the abdominal ultrasound after excluding other diseases of this organ. RESULTS A total of 297 proteins have been identified. Thirty-seven proteins (responsible for inflammation, stress response, and regulation of this process) differentiating both experimental groups were identified. Up-regulated proteins included afamin, retinol-binding protein-4, complement components, and hemopexin; while serum protease inhibitors, clusterin, immunoglobulin chains, and vitamin D binding protein were found in the down-regulated group. The correlation between selected proteins and indicators of noninvasive assessment of liver fibrosis (APRI, FIB-4) as well as differences between the serum proteome of patients with normal weight, overweight, and obesity were also assessed. CONCLUSION The plasma protein profile is significantly altered in nonalcoholic liver disease in children and may prove to be a valuable source of biomarkers to evaluate the extent of liver disease.
