Dietary Variable

Mexican-origin (MO) adults have among the highest rates of nonalcoholic fatty liver disease (NAFLD) placing them at increased risk of liver cancer. Evidence suggests that a single nucleotide polymorphism (SNP) in the PNPLA3 gene, rs738409, increases the risk and progression of NAFLD and may modify the relationship between certain dietary factors and liver steatosis. The purpose of this study was to identify whether interactions exist between specific dietary factors and rs738409 genotype status among MO adults in relation to levels of liver steatosis. We analyzed cross-sectional data from a sample of 288 MO adults. Participants completed at least two 24-h dietary recalls. Multiple linear regression was performed assuming an additive genetic model to test the main effects of several dietary variables on levels of hepatic steatosis, adjusting for covariates. To test for effect modification, the product of the genotype and the dietary variable was included as a covariate in the model. No significant association between dietary intake and level of hepatic steatosis was observed, nor any significant gene-diet interactions. Our findings suggest that dietary intake may have the same magnitude of protective or deleterious effect even among MO adults with high genetic risk for NAFLD and NAFLD progression.

Abstract Background Nonalcoholic fatty liver disease (NAFLD) is a hepatic manifestation of metabolic disease and independently affects the development of cardiovascular (CV) disease. We investigated whether hepatic steatosis and/or fibrosis are associated with the development of incident heart failure (iHF), hospitalized HF (hHF), mortality, and CV death in both the general population and HF patients. Methods We analyzed 778,739 individuals without HF and 7445 patients with pre-existing HF aged 40 to 80 years who underwent a national health check-up from January 2009 to December 2012. The presence of hepatic steatosis and advanced hepatic fibrosis was determined using cutoff values for fatty liver index (FLI) and BARD score. We evaluated the association of FLI or BARD score with the development of iHF, hHF, mortality and CV death using multivariable-adjusted Cox regression models. Results A total of 28,524 (3.7%) individuals in the general population and 1422 (19.1%) pre-existing HF patients developed iHF and hHF respectively. In the multivariable-adjusted model, participants with an FLI ≥ 60 were at increased risk for iHF (hazard ratio [HR], 95% confidence interval [CI], 1.30, 1.24–1.36), hHF (HR 1.54, 95% CI 1.44–1.66), all-cause mortality (HR 1.62, 95% CI 1.54–1.70), and CV mortality (HR 1.41 95% CI 1.22–1.63) in the general population and hHF (HR 1.26, 95% CI 1.21–1.54) and all-cause mortality (HR 1.54 95% CI 1.24–1.92) in the HF patient group compared with an FLI < 20. Among participants with NAFLD, advanced liver fibrosis was associated with increased risk for iHF, hHF, and all-cause mortality in the general population and all-cause mortality and CV mortality in the HF patient group (all p < 0.05). Conclusion Hepatic steatosis and/or advanced fibrosis as assessed by FLI and BARD score was significantly associated with the risk of HF and mortality.

Background and Objectives In the last few decades,Nonalcoholic Fatty Liver Disease (NAFLD) has become a common health issue that leads to serious complications like cirrhosis, cardiovascular disease, etc. Insulin resistance (IR) is the key pathogenic factor for NAFLD. The young medicos being habituated in stressful and sedentary lifestyle and representative of the youth as well can fully justify their selection as study population and help to build social awareness by emphasizing the importance of early lifestyle modifications in preventing or delaying the severe complications of NAFLD. This study is aiming to find out if there is any correlation of hepatic steatosis with IR, Alanine Transaminases (ALT), Aspartate Transaminases (AST) or Gama Glutamyl Transferases (GGT) and also to identify if one enzyme is better correlating with hepatic steatosis than others in the scenario of Insulin Resistance among young medicos. METHODS: 132 medical students of North Bengal Medical College, aged between 18-25 years were included in this institution based observational cross-sectional study. Their Fasting Insulin, glucose, ALT, AST, GGT were measured, and IR was calculated by the Homeostatic Assessment of Insulin Resistance (HOMA-IR) calculator. Sonography was done to assess Hepatic steatosis. RESULTS: Among 132 subjects normal, grade 1 and grade 2 fatty changes have been found in 67.4%, 25%, and 7.6% of the study population respectively. The Grouping was done using the cut-off value of IR (i.e. subjects with IR<1.525 vs. IR≥1.525). Significant differences were found in the mean values of ALT, AST, GGT between groups. Significant positive concordances were found between enzymes ALT, GGT, and hepatic steatosis in subjects having IR ≥ 1.525.Regression analysis showed that higher GGT values have a stronger positive correlation with hepatic steatosis than ALT among the same. Interpretation and Conclusion From this study, we can interpret that subjects having higher GGT values are better associated with steatosis than those having higher ALT values and can lead us to the conclusion that GGT might be an important independent marker for NAFLD associated with IR. Furthermore, such observations may suggest considering GGT as a marker for assessing the severity of fatty liver irrespective of etiopathogenesis, though the population-based vivid evaluation is highly recommended.

ABSTRACTObjective: To access the physical work capacity and cognition of underprivileged anemic adolescent, hemoglobin (Hb) of subjects was assessed forthe adolescence under 17-20 years of age by undergoing survey.Methods: This is a cross-sectional study, conducted in students of 1st year of Saveetha Dental College. The general information about age, Hb level(Sahli’s method), knowledge about anemia, status of menstruation, and regarding the consumption of various diet factors were recorded on astructured questionnaire. Due to feasibility and cost effectiveness, Hb estimation was done by Sahli’s hemoglobinometer.Results: Our study proved that now a days adolescence is not much more prone to anemia. And mostly 40% of adolescence were having mild anemia.This mild anemia can be improved by dietary intake and bioavailability of iron, nutritional supplementation of iron and folic acid (IFA) tablets, andfortification of edible dietary items with iron. This difference was statistically significant (Chi-square value 4.848, p<0.001).Conclusion: The study was mainly done for adolescence awareness on anemia. Iron deficiency anemia occurs most frequently in adolescence becauseaccelerated physical growth both in boys and girls and menstruation and dieting for fear of obesity in female teenagers. The prevalence of anemianecessitates pragmatic intervention to improve the dietary intake, nutritional supplement of IFA tablets.Keywords: Adolescence, Dietary factors, Knowledge about anemia.

The Relationship

Examining the relationship between glucose intolerance and dietary intake in genetically similar populations with different dietary patterns and rates of type 2 diabetes may provide important insights into the role of diet in the pathogenesis of this disease. The objective of the present study was to assess the relationship between dietary variables and dysglycaemia/type 2 diabetes among three populations of African origin. The study design consists of a cross-sectional study of men and women of African descent aged 24–74 years from Cameroon (n 1790), Jamaica (n 857) and Manchester, UK (n 258) who were not known to have diabetes. Each participant had anthropometric measurements and underwent a 2 h 75 g oral glucose tolerance test. Habitual dietary intake was estimated with quantitative FFQ, developed specifically for each country. The age-adjusted prevalence of undiagnosed type 2 diabetes in Cameroon was low (1·1 %), but it was higher in Jamaica (11·6 %) and the UK (12·6 %). Adjusted generalised linear and latent mixed models used to obtain OR indicated that each 1·0 % increment in energy from protein, total fat and saturated fats significantly increased the odds of type 2 diabetes by 9 (95 % CI 1·02, 1·16) %, 5 (95 % CI, 1·01, 1·08) % and 16 (95 % CI 1·08, 1·25) %, respectively. A 1 % increase in energy from carbohydrates and a 0·1 unit increment in the PUFA:SFA ratio were associated with significantly reduced odds of type 2 diabetes. The results show independent effects of dietary factors on hyperglycaemia in African origin populations. Whether modifying intake of specific macronutrients helps diabetes prevention needs testing in randomised trials.

Objective: Primary hypobetalipoproteinemia is characterized by LDL-C (low-density lipoprotein cholesterol) concentrations below the fifth percentile. Primary hypobetalipoproteinemia mostly results from heterozygous mutations in the APOB and PCSK9 genes, and a polygenic origin is hypothesized in the remaining cases. Hypobetalipoproteinemia patients present an increased risk of nonalcoholic fatty liver disease and steatohepatitis. Here, we compared hepatic alterations between monogenic, polygenic, and primary hypobetalipoproteinemia of unknown cause. Approach and Results: Targeted next-generation sequencing was performed in a cohort of 111 patients with hypobetalipoproteinemia to assess monogenic and polygenic origins using an LDL-C-dedicated polygenic risk score. Forty patients (36%) had monogenic hypobetalipoproteinemia, 38 (34%) had polygenic hypobetalipoproteinemia, and 33 subjects (30%) had hypobetalipoproteinemia from an unknown cause. Patients with monogenic hypobetalipoproteinemia had lower LDL-C and apolipoprotein B plasma levels compared with those with polygenic hypobetalipoproteinemia. Liver function was assessed by hepatic ultrasonography and liver enzymes levels. Fifty-nine percent of patients with primary hypobetalipoproteinemia presented with liver steatosis, whereas 21% had increased alanine aminotransferase suggestive of liver injury. Monogenic hypobetalipoproteinemia was also associated with an increased prevalence of liver steatosis (81% versus 29%, P <0.001) and liver injury (47% versus 0%) compared with polygenic hypobetalipoproteinemia. Conclusions: This study highlights the importance of genetic diagnosis in the clinical care of primary hypobetalipoproteinemia patients. It shows for the first time that a polygenic origin of hypobetalipoproteinemia is associated with a lower risk of liver steatosis and liver injury versus monogenic hypobetalipoproteinemia. Thus, polygenic risk score is a useful tool to establish a more personalized follow-up of primary hypobetalipoproteinemia patients.

Background: An association between low muscle mass and nonalcoholic fatty liver disease (NAFLD) has been suggested. We investigated this relationship using controlled attenuation parameter (CAP). Methods: A retrospective cohort of subjects had liver FibroScan® (Echosens, Paris, France) and bioelectrical impedance analyses during health screening exams. Low muscle mass was defined based on appendicular skeletal muscle mass/body weight ratios of one (class I) or two (class II) standard deviations below the sex-specific mean for healthy young adults. Results: Among 960 subjects (58.1 years; 67.4% male), 344 (45.8%, class I) and 110 (11.5%, class II) had low muscle mass. After adjusting for traditional metabolic risk factors, hepatic steatosis, defined as a CAP ≥ 248 dB/m, was associated with low muscle mass (class I, odds ratio (OR): 1.96, 95% confidence interval (CI): 1.38–2.78; class II, OR: 3.33, 95% CI: 1.77–6.26). A dose-dependent association between the grade of steatosis and low muscle mass was also found (class I, OR: 1.88, for CAP ≥ 248, <302; OR: 2.19, in CAP ≥ 302; class II, OR: 2.33, for CAP ≥ 248, <302; OR: 6.17, in CAP ≥ 302). High liver stiffness was also significantly associated with an increased risk of low muscle mass (class I, OR: 1.97, 95% CI: 1.31–2.95; class II, OR: 2.96, 95% CI: 1.51–5.78). Conclusion: Hepatic steatosis is independently associated with low muscle mass in a dose-dependent manner. The association between hepatic steatosis and low muscle mass suggests that particular attention should be given to subjects with NAFLD for an adequate assessment of muscle mass.

Abstract Background Obesity and fatty liver steatosis are already considered metabolic risk factors that may aggravate the severity of COVID-19. This study aims to investigate the correlation between COVID-19 severity, body mass index, and hepatic steatosis. MethodsConsecutive patients with laboratory-confirmed COVID-19, admitted to a hospital devoted to COVID-19 patients, were enrolled in the study. COVID-19 severity was classified as severe versus non-severe based on the condition at time of admission to ICU. Obesity was assessed by Body Mass Index (BMI). CT-scan of the patient liver was used to check for the hepatic steatosis. Fibrosis-4 score was calculated.Results230 patients were enrolled in this study. Obesity strongly and positively correlated with severe COVID-19 illness. Hepatic steatosis had rather less of a correlation with COVID-19 severity. Multivariable-adjusted association between hepatic steatosis or obesity, or both (as exposure) and COVID-19 severity (as the outcome) revealed an increased risk of severe COVID-19 illness with obesity, with hepatic steatosis, and with hepatic steatosis among obese patients. ConclusionsBMI remained the most noticeable factor that strongly correlated with COVID-19 severity. Obesity even in the absence of hepatic steatosis greatly increased the risk of severe COVID-19. This association remained significant after adjusting for likely confounders. The presence of liver steatosis even in non-obese patients increased the risk of severe COVID-19 but to a much lesser degree compared to obesity. The risk of steatosis to COVID-19 severity was greater in those with than those without obesity. This association also remained significant after adjusting for likely confounders

Objective: Sphingolipids including ceramides are biological active components of all cell membranes. They play a great role in cell interconnections in the process of proliferation, maturation, cell apoptosis and any fluctuations of their level can lead to development of metabolic diseases such as type 2 diabetes (T2D) and nonalcoholic fatty liver disease. Nevertheless, there is lack of information about what type of ceramides play a role in aforementioned diseases. Here we investigated the relationship between the serum level of some type of ceramides and parameters of metabolic syndrome that is commonly present in obese patients. Design: We performed cross-sectional study in two groups. One of them was control group – lean healthy people (n=10, body mass index, BMI 21, 2±1, 89) and the second group included patients with the obesity (n=24, BMI 33, 9±3, 1). We quantified the levels of serum ceramide by liquid chromatography-mass spectrometry, analyzed the parameters for insulin resistance, liver function and lipid metabolism by biochemical blood test. Results: The subjects with obesity had elevated level of ceramide C16:0, C18:0, C24:0 comparing with control group (p<0,001). As results of our study, we found correlation of the level ceramide C16:0, C18:0, C24:0 with the results of steatometry and some metabolic parameters (glycosylated hemoglobin (Hb A1C), cholesterol). Conclusion: These results demonstrate that obese subjects had increased level of ceramide C16:0, C18:0, C24:0 that correlated with some metabolic parameters supposedly recognizing them as new biomarkers of metabolic syndrome.

Background: There is no evidence available on the association of Fetuin-B with chronic kidney disease (CKD), and mechanisms linking nonalcoholic fatty liver disease (NAFLD) to CKD are not fully understood. We aimed to explore the independent associations and potential mechanisms of Fetuin-B and NAFLD with CKD. Methods: A cross-sectional study of 1,072 Chinese adults who underwent serum Fetuin-B test and hepatic ultrasonography scanning was conducted in Xiamen, China. CKD was defined as estimated glomerular filtration rate < 60 mL/min/1.73 m2 and/or the presence of albuminuria. Results: Subjects with CKD showed significantly higher prevalence of NAFLD (69.5 vs. 57.2%, p < 0.001) and serum Fetuin-B levels (4.32 ± 1.45 vs. 4.05 ± 1.36 µg/mL, p = 0.007) than their controls. Increased serum Fetuin-B was also significantly associated with increased levels of fasting insulin and homeostasis model assessment – insulin resistance (both p values < 0.05). NAFLD and higher serum Fetuin-B were significantly associated with increased risk of CKD, and the unadjusted ORs (95% CIs) were 1.701 (1.256–2.303, p = 0.001) and 1.213 (1.053–1.399, p = 0.008, per SD increase of Fetuin-B), respectively. With adjustment for potential confounding factors, including metabolic/insulin resistance syndrome, NAFLD but not serum Fetuin-B was still significantly associated with increased risk of CKD, and the adjusted ORs (95% CIs) were 1.820 (1.327–2.496, p < 0.001) and 1.116 (0.959–1.298, p = 0.153, per SD increase of Fetuin-B), respectively. Conclusions: Fetuin-B might link NAFLD to CKD via inducing insulin resistance, and NAFLD contributes independently to the pathogenesis of CKD via multiple mechanisms besides of metabolic/insulin resistance syndrome.
