Rahimlou M, Baghdadi G, Khodi A, Rahimi Z, Saki N, Banaei Jahromi N, Cheraghian B, Tavasolian R, Hosseini SA. Polyphenol consumption and Nonalcoholic fatty liver disease risk in adults. Sci Rep 2024; 14:6752. [PMID: 38514756 PMCID: PMC10957908 DOI: 10.1038/s41598-024-57416-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Accepted: 03/18/2024] [Indexed: 03/23/2024] Open
Abstract
In this cross-sectional investigation, the primary objective was to explore the correlation between the consumption of polyphenols and the likelihood of non-alcoholic fatty liver disease (NAFLD) in the adult population participating in the Hoveyzeh cohort. Data from the Hoveyzeh cohort study, part of the Persian Cohort Study, involving 10,009 adults aged 35-70, were analyzed. Exclusions were made for missing data, extreme energy intake, and liver cancer patients. Dietary habits were assessed using a food frequency questionnaire, and polyphenol intake was calculated using the Phenol Explorer database. Logistic regression analyses, adjusted for confounders, were performed to assess the relationship between polyphenol subclasses (total polyphenols, total flavonoids, phenolic acid, and lignin) and NAFLD. Among 9894 participants, those in the highest quintile of total polyphenol (OR 0.65, CI 0.5-0.84; P = 0.007), phenolic acid (OR 0.67, CI 0.52-0.86; P < 0.001), and lignin intake (OR 0.69, CI 0.52-0.87; P = 0.001) demonstrated lower odds of NAFLD compared to the lowest quintile, even after adjusting for confounding factors. However, no significant association was found between total flavonoid intake and NAFLD (OR 1.26, CI 0.96-1.67; P = 0.47). Subgroup analysis indicated a significant inverse association between total polyphenols and NAFLD in women (OR 0.64, CI 0.42-0.93; P = 0.001). Higher intake of total polyphenols, phenolic acid, and lignin was associated with reduced odds of NAFLD among adults in the Hoveyzeh cohort. This suggests that dietary patterns rich in these polyphenols may play a role in mitigating the risk of NAFLD. Further interventional and longitudinal studies are needed to validate these findings and explore potential preventive strategies involving polyphenol-rich diets.

The effects of high-intensity interval training and Iranian propolis extract on serum levels of TRPV4 and CYP2E1 proteins in patients with nonalcoholic fatty liver. LA TUNISIE MEDICALE 2024; 102:19-25. [PMID: 38545725 PMCID: PMC11261517 DOI: 10.62438/tunismed.v102i1.4669] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Accepted: 11/18/2023] [Indexed: 07/25/2024]
Abstract
INTRODUCTION Non-alcoholic fatty liver disease (NAFLD) is the most common cause of liver failure, fibrosis, cirrhosis, and liver cancer, which can eventually lead to death. AIM To investigate the effects of high-intensity interval training (HIIT) and iranian propolis extract on serum levels of transient receptor potential cation channel subfamily V member 4 (TRPV4) and cytochrome P450 2E1 (CYP2E1) proteins in patients with NAFLD. METHODS Thirty-two patients with NAFLD (mean±standard deviation of age: 45.1±3.6 years; body mass index: 30.0±3.6 kg/m2) were assigned in a randomized control trial to one of the following groups: HIIT (n=8), propolis supplement (n=8), propolis + HIIT (n=8), and controls (n=8). The subjects participated in eight weeks of HIIT (one bout of 1-min intervals at 80-95% of the maximal heart-rate, interspersed by two min at 50-55% of the reserve heart-rate). The Propolis supplement was taken three times a day by the patients in the form of 50 mg tablet after the main meals. Body composition, liver injury test (eg; Alanine- and Aspartate- aminotransferase levels), liver ultrasound and serum levels of TRPV4 and CYP2E1 were measured before and after intervention. One-way analysis of variance was used to compare post-tests among the groups. RESULTS HIIT significantly reduced serum levels of TRPV4 protein (p=0.001). The reduction in CYP2E1 was not significant in HIIT group (p=0.075). Propolis consumption had no significant effect on serum levels of CYP2E1 protein (p=0.059), and TRPV4 (p=0.072). There was a significant decrease in TRPV4 and CYP2E1 in the HIIT (p=0.001) and propolis supplement (p=0.032) groups. CONCLUSION HIIT and propolis supplementation can be used to reduce TRPV4 and CYP2E1, which in turn reduces oxidative stress and inflammation in patients with NAFLD.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a systemic disorder with a complex multifactorial and heterogeneous pathogenesis and has become the most common cause of chronic liver disease in many countries around the world. Numerous studies in Iran have presented different results on the prevalence and risk factors of NAFLD, in this study, which has been done in a systematic review and meta-analysis, provides a good estimate of the prevalence and risk factors of the disease in Iran. Following the peer review of electronic search strategies (PRESS and the preferred reporting items for systematic reviews and meta-analyses [PRISMA] statement, we searched Web of Science, PubMed, Embase, Scopus, and Persian scientific searcher (Elmnet) from inception to September 19, 2022. In the present study, 71 articles were reviewed for qualitative and meta-analysis. The overall mean prevalence of NAFLD in children studies was 22.4% (95% confidence interval [CI]: 10.9% to 33.9%). The prevalence was notably higher in adult studies 40.5% (95% CI: 35.1% to 46%). In 24 studies, the association between NAFLD and sex was reported, 10 of which showed significant relationships. Out of 46 studies observed that NAFLD prevalence increased significantly with body mass index (BMI). Eight out of 14 studies reported significant associations between FBS and NAFLD in children's studies. Though Iran has a high NAFLD prevalence compared to most areas, and due to the unfavorable situation of risk factors contributing to the NAFLD, it is necessary to take the necessary interventions to control these risk factors and prevent NAFLD.

Abstract
Background Non-alcoholic fatty liver disease (NAFLD) is the world's most common etiology of chronic liver disease. In this systematic review and meta-analysis, we estimated the prevalence of NAFLD in the Iranian children and adult population. Methods A comprehensive search of five international databases, including PubMed, ISI/WOS, ProQuest, Scopus, and Google Scholar, was done from inception to Nov 2022. Studies on NAFLD patients and their risk factors were selected for meta-analysis. The quality of the included studies was assessed by The Joanna Briggs Institute (JBI) Critical Appraisal Checklist for cross-sectional, and cohort studies. The heterogeneity between studies was investigated using Cochran test and I2 statistics. Random and fixed effect models were used for heterogenic and non-heterogenic studies, respectively. We used Comprehensive Meta-Analysis version 3 for conducting meta-analysis. Results Twenty studies were finally included. The total prevalence of NAFLD in children, boys, and girls was 6.7% (95% CI: 0.02-0.18), 12.5% (95% CI: 0.04-0.29) and, 10.1% (95% CI: 0.04-0.21), respectively. The total prevalence of NAFLD in obese children, obese boys, and obese girls was 42% (95% CI: 0.18-0.69), 44% (95% CI: 0.13-0.80), and 33 % (95% CI: 0.13-0.62), respectively. The total prevalence of NAFLD in adults was 36.9% (95% CI: 0.31-0.42). The prevalence of NAFLD in men and women was 33.8% (95% CI: 0.27-0.41) and 29.9% (95% CI: 0.21-0.40), respectively. Conclusion NAFLD prevalence in Iranian adults and obese children is considerable; however, data about the children population was insufficient.

Abstract
Consumption of phytochemical-rich foods relates to the prevention of chronic diseases. In this study we assessed the dietary phytochemical index (PI) in metabolic parameters, liver enzymes, and severity of fibrosis among nonalcoholic fatty liver disease patients. This cross-sectional study was conducted on 210 patients with NAFLD. Fibrosis-4 index (FLB4), nonalcoholic fatty liver disease fibrosis score (NFS), FBS, lipids profile, AST, ALT, ALP, and GGT were measured. PI was calculated through the information obtained from a validated semi-quantitative food frequency. Multiple regression models were used to estimate mean difference changes in the evaluated variables associated with various dietary PI. Participants' mean ± SD of age and BMI were 39.23 ± 10.52 and 24.40 ± 2.64, respectively. We found that DPI is inversely associated with serum TG, TC, and LDL-C and directly associated with serum HDL-C and a higher score in DPI is associated with lower scores in NFS and FIB-4. Multivariate linear regression showed that there is an inverse association between DPI and AST, ALT, ALP, GGT, NFS, and FIB-4. Higher dietary PI could impact on reduction of NAFLD progression and improvement of metabolic parameters.

Abstract
Background Non-alcoholic fatty liver disease (NAFLD) is one of the most common forms of chronic liver disease that affects about 25% of the general population. No definitive treatment for NAFLD has been identified yet. The aim was to determine the effect of atorvastatin (ATO) and flaxseed on related indicators of NAFLD-induced fat/fructose-enriched diet (FFD). Materials and Methods Forty male Wistar rats were divided into five groups. NAFLD groups received FFD and carbon tetrachloride (CCl4) to induce NAFLD. After intervention with ATO (10 mg/kg/day) and/or flaxseed (7.5 g/kg/day), liver enzymes and lipid profiles in serum were determined at eight week of interventions. Results Triglycerides (TG) and cholesterol (CHO) in FFD + ATO, FFD + flaxseed, and FFD + ATO + flaxseed had a significant decrease and low-density lipoprotein (LDL) level and LDL/high-density lipoprotein (HDL) ratio showed a significant increase in the FFD + flaxseed compared to the FFD. The levels of aspartate transaminase (AST), alanine transaminase (ALT), and gamma-glutamyltransferase (GGT) were significantly reduced in the FFD + ATO, FFD + flaxseed, and the FFD + ATO + flaxseed. In addition, Alkaline phosphatase (ALP) levels were significantly different between normal and FFD. Fasting blood sugar (FBS) levels were significantly different in the FFD + flaxseed and the FFD + ATO + flaxseed compared to the FFD. Conclusion ATO therapy along with flaxseed controls NAFLD-related indices and FBS. Therefore, it can be stated with caution that ATO and flaxseed can be used to improve lipid profile and reduce the complications of NAFLD.

Abstract
Context: Non-alcoholic fatty liver disease (NAFLD) is progressing considerably worldwide. Identifying the risk factors of NAFLD is a critical step in preventing its progression. Methods: In November 2022, two independent researchers studied seven databases, including PubMed, ISI/WoS, ProQuest, Scopus, SID, Magiran, and Google Scholar, and reference list of relevant articles, searching studies that assessed NAFLD risk factors in the Iranian adult population. Heterogeneity between studies was assessed by Cochran’s test and its composition using I2 statistics. A random-effects model was used when heterogeneity was observed; otherwise, a fixed-effects model was applied. Egger’s regression test and Trim-and-Fill analysis were used to assess publication bias. Comprehensive Meta-analysis software (version 3) was used for the analyses of the present study. Results: The results of this study showed significant associations between NAFLD with age [n = 15, odds ratio (OR) = 2.12, 95% CI: 1.79 - 2.51], body mass index (n = 46, OR = 5.00, 95% CI: 3.34 - 7.49), waist circumference (n = 20, OR = 6.37, 95% CI: 3.25 - 12.48), waist-to-hip ratio (n = 17, OR = 4.72, 95% CI: 3.93 - 5.66), total cholesterol (n = 39, OR = 1.80, 95% CI: 1.52 - 2.13), high-density lipoprotein (n = 37, OR = 0.53, 95% CI: 0.44 - 0.65), low-density lipoprotein (n = 31, OR = 1.68, 95% CI: 1.38 - 2.05), triglyceride (n = 31, OR = 3.21, 95% CI: 2.67 - 3.87), alanine aminotransferase (n = 26, OR = 4.06, 95% CI: 2.94 - 5.62), aspartate aminotransferase (n = 27, OR = 2.16, 95% CI: 1.50 - 3.12), hypertension (n = 13, OR = 2.53, 95% CI: 2.32 - 2.77), systolic blood pressure (n = 13, OR = 1.83, 95% CI: 1.53 - 2.18), diastolic blood pressure (n = 14, OR = 1.80, 95% CI: 1.48 - 2.20), fasting blood sugar (n = 31,OR = 2.91, 95% CI: 2.11- 4.01), homeostatic model assessment for insulin resistance (n = 5, OR = 1.92, 95% CI: 1.48 - 2.59), diabetes mellitus (n = 15, OR = 3.04, 95% CI: 2.46 - 3.75), metabolic syndrome (n = 10, OR = 3.56, 95% CI: 2.79 - 4.55), and physical activity (n = 11, OR = 0.32, 95% CI: 0.24 - 0.43) (P < 0.05). Conclusions: In conclusion, several factors are significantly associated with NAFLD. However, anthropometric indices had the strongest relationship with NAFLD in the Iranian adult population.

Abstract
BACKGROUND & AIMS The increasing rates of obesity and type 2 diabetes mellitus may lead to increased prevalence of nonalcoholic fatty liver disease (NAFLD). We aimed to determine the current and recent trends on the global and regional prevalence of NAFLD. METHODS Systematic search from inception to March 26, 2020 was performed without language restrictions. Two authors independently performed screening and data extraction. We performed meta-regression to determine trends in NAFLD prevalence. RESULTS We identified 17,244 articles from literature search and included 245 eligible studies involving 5,399,254 individuals. The pooled global prevalence of NAFLD was 29.8% (95% confidence interval [CI], 28.6%-31.1%); of these, 82.5% of included articles used ultrasound to diagnose NAFLD, with prevalence of 30.6% (95% CI, 29.2%-32.0%). South America (3 studies, 5716 individuals) and North America (4 studies, 18,236 individuals) had the highest NAFLD prevalence at 35.7% (95% CI, 34.0%-37.5%) and 35.3% (95% CI, 25.4%-45.9%), respectively. From 1991 to 2019, trend analysis showed NAFLD increased from 21.9% to 37.3% (yearly increase of 0.7%, P < .0001), with South America showing the most rapid change of 2.7% per year, followed by Europe at 1.1%. CONCLUSIONS Despite regional variation, the global prevalence of NAFLD is increasing overall. Policy makers must work toward reversing the current trends by increasing awareness of NAFLD and promoting healthy lifestyle environments.

Abstract
The prevalence of nonalcoholic fatty liver disease (NAFLD) is rising worldwide, paralleling the epidemic of obesity. The liver is a key organ for the metabolism of proteins, fats and carbohydrates. Various types of fats and carbohydrates in isocaloric diets differently influence fat accumulation in the liver parenchyma. Therefore, nutrition can manage hepatic and cardiometabolic complications of NAFLD. Even moderately reduced caloric intake, which leads to a weight loss of 5%-10% of initial body weight, is effective in improving liver steatosis and surrogate markers of liver disease status. Among dietary patterns, the Mediterranean diet mostly prevents the onset of NAFLD. Furthermore, this diet is also the most recommended for the treatment of NAFLD patients. However, clinical trials based on the dietary interventions in NAFLD patients are sparse. Since there are only a few studies examining dietary interventions in clinically advanced stages of NAFLD, such as active and fibrotic steatohepatitis, the optimal diet for patients in these stages of the disease must still be determined. In this narrative review, we aimed to critically summarize the associations between different dietary patterns, obesity and prevention/risk for NAFLD, to describe specific dietary interventions’ impacts on liver steatosis in adults with NAFLD and to provide an updated overview of dietary recommendations that clinicians potentially need to apply in their daily practice.

Dietary phytochemical consumption is inversely associated with liver alkaline phosphatase in Middle Eastern adults. World J Hepatol 2022; 14:1006-1015.

Abstract
BACKGROUND The hepatoprotective effects of phytochemicals are controversial. A dietary phytochemical index (DPI) has been suggested as an alternative method for quantifying the phytochemical content of foods.
AIM To assess the DPI in relation to liver function tests among a representative sample of Iranian adults.
METHODS A total of 5111 participants aged 35-70 years old were included in this cross-sectional study by a multistage cluster random sampling method. Dietary intakes were collected by a validated and reliable food frequency questionnaire with 121 items. DPI was calculated by the percent of daily energy intake taken from phytochemical-rich foods. Fasting serum concentrations of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and gamma glutamyl transferase (GGT) were determined. Linear regression was used to investigate the association between DPI and levels of liver enzymes using crude and adjusted models.
RESULTS There was an inverse association between DPI score and serum ALP in the crude model (β = -0.05; P < 0.001). This association remained significant after adjustment for body mass index, age, smoking, energy intake, history of diabetes, and education (β = -0.03; P = 0.01). No significant associations were found between DPI score and serum levels of AST, ALT, and GGT. The individuals with the highest DPI scores consumed significantly higher amounts of fruits, vegetables, legumes, nuts, and cereals, yet were shown to have significantly higher serum total cholesterol and low-density lipoprotein cholesterol, as well as several other metabolic abnormalities.
CONCLUSION Higher adherence to phytochemical-rich foods was associated with lower levels of ALP, but no change in other liver enzymes. Those with higher DPI scores also consumed food items associated with a healthier overall dietary pattern; however, they also presented several unexpected metabolic derangements. Additional randomised trials are needed to better determine the effects of phytochemical-rich foods on liver function.

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.

BMC Med Inform Decis Mak 2021; 21:58. [PMID: 34330261 PMCID: PMC8323210 DOI: 10.1186/s12911-021-01432-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2021] [Accepted: 02/09/2021] [Indexed: 12/24/2022] Open
Abstract
Background A new learning-based patient similarity measurement was proposed to measure patients’ similarity for heterogeneous electronic medical records (EMRs) data. Methods We first calculated feature-level similarities according to the features’ attributes. A domain expert provided patient similarity scores of 30 randomly selected patients. These similarity scores and feature-level similarities for 30 patients comprised the labeled sample set, which was used for the semi-supervised learning algorithm to learn the patient-level similarities for all patients. Then we used the k-nearest neighbor (kNN) classifier to predict four liver conditions. The predictive performances were compared in four different situations. We also compared the performances between personalized kNN models and other machine learning models. We assessed the predictive performances by the area under the receiver operating characteristic curve (AUC), F1-score, and cross-entropy (CE) loss. Results As the size of the random training samples increased, the kNN models using the learned patient similarity to select near neighbors consistently outperformed those using the Euclidean distance to select near neighbors (all P values < 0.001). The kNN models using the learned patient similarity to identify the top k nearest neighbors from the random training samples also had a higher best-performance (AUC: 0.95 vs. 0.89, F1-score: 0.84 vs. 0.67, and CE loss: 1.22 vs. 1.82) than those using the Euclidean distance. As the size of the similar training samples increased, which composed the most similar samples determined by the learned patient similarity, the performance of kNN models using the simple Euclidean distance to select the near neighbors degraded gradually. When exchanging the role of the Euclidean distance, and the learned patient similarity in selecting the near neighbors and similar training samples, the performance of the kNN models gradually increased. These two kinds of kNN models had the same best-performance of AUC 0.95, F1-score 0.84, and CE loss 1.22. Among the four reference models, the highest AUC and F1-score were 0.94 and 0.80, separately, which were both lower than those for the simple and similarity-based kNN models. Conclusions This learning-based method opened an opportunity for similarity measurement based on heterogeneous EMR data and supported the secondary use of EMR data.

Abstract
Background Nutrition is a modifiable risk factor that plays an important role in the prevention or delaying of the onset of non-alcoholic fatty liver disease (NAFLD). Previous studies have focused on NAFLD and individual nutrients, which does not take into account combinations of food that are consumed. Therefore, we aimed to investigate the relationship between major dietary patterns and NAFLD.
Methods This case–control study was conducted on 225 newly diagnosed NAFLD patients and 450 healthy controls. Usual dietary intake over the preceding year was assessed using a validated 168-item semi-quantitative food frequency questionnaire. Major dietary patterns were determined by exploratory factor analysis. Results Three dietary patterns, including "western dietary pattern", "healthy dietary pattern", and "traditional dietary pattern" were identified. Subjects in the highest tertile of healthy dietary pattern scores had a lower odds ratio for NAFLD than those in the lowest tertile. Compared with those in the lowest tertile, people in the highest tertile of “western dietary pattern” scores had greater odds for NAFLD. After adjusting for potential confounding factors, “western dietary pattern” had a positive significant effect on NAFLD occurrence. In contrast, “healthy dietary pattern” was associated with a decreased risk of NAFLD. Furthermore, Higher consumption of the “traditional dietary pattern” was significantly associated with NAFLD, albeit in the crude model only. Conclusion This study indicated that healthy and western dietary patterns may be associated with the risk of NAFLD. The results can be used for developing interventions in order to promote healthy eating for the prevention of NAFLD.

Abstract
BACKGROUND/AIMS The aim of the present study was to investigate the relationship between non-alcoholic fatty liver disease (NAFLD) and neck circumference (NC) and to compare the NC predictive value with other anthropometric indices in the prediction of NAFLD and metabolic syndrome (MetS) as well as to find the NC cut-off point for the prediction of NAFLD and MetS in an Iranian population. MATERIALS AND METHODS A total of 590 individuals who fulfilled our criteria were enrolled in the study. Anthropometric measurements, physical examinations, and abdominal ultrasonography were performed by trained staff. Blood samples for biochemical tests were also obtained after fasting for 12 h. RESULTS Neck circumference was associated with NAFLD and MetS in both genders (p<0.0001) and remained significant even after adjustment for possible confounding factors. It was also significantly associated with other anthropometric indices, such as fatty liver severity, aspartate aminotransferase, alanine aminotransferase, fasting blood sugar, triglycerides, low-density lipoprotein, systolic and diastolic blood pressure, and family history of diabetes in both sexes (p<0.05). There was a significant negative correlation between high-density lipoprotein levels and NC in both sexes (p<0.001). CONCLUSION Neck circumference was significantly correlated with NAFLD and MetS. In addition, it had the highest predictive value for NAFLD and MetS among other common anthropometric indices. Therefore, it can be used as a simple and feasible tool for screening NAFLD in a large population.

Abstract
Background This study investigated the prevalence and association of liver transaminases in type 2 diabetes mellitus (T2DM) patients at King Abdulaziz University Hospital (KAUH), Jeddah, Saudi Arabia. Methods This retrospective, cross-sectional study was carried out on 211 T2DM patients at KAUH in 2017, and the Research Ethics Committee of KAUH approved this study. The data were analyzed on SPSS 21 (IBM Corp., Armonk, NY, US). The association of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) with several risk factors was computed by the chi-square test. The odds ratio with a 95% confidence interval (CI) was also calculated. Results The mean age of study participants was 60 ± 13.43 years; 143 (67.8%) were female while 68 (32.2%) were male. Serum AST levels were elevated in 6.16% (10.3% in males, 4.2% in females). Elevated ALT levels were found in 7.58% (11.8% in males, 5.6% in females) (Table 2). The probability of rising AST levels increased with age (OR = 2.59 for patients aged 46-65) and with male gender (OR = 2.65, CI: 0.84-8.12). Additionally, the probability of rising ALT levels increased with male gender (OR = 2.25, CI: 0.80-6.27), low-density lipoproteins (LDL-C) (OR = 2.11, CI: 0.73-6.04), and triglycerides (TG) (OR = 2.08, CI: 0.739-5.87). No statistically noteworthy association was observed between elevated levels of AST and ALT with gender, age, body mass index (BMI), glycated hemoglobin (HbA1c), TG, total cholesterol (TC), LDL-C, and high-density lipoprotein cholesterol (HDL-C) levels, smoking, or hypertension. Conclusion Higher ALT and AST levels were found in T2DM patients but with no statistically significant link between elevated levels and gender, age, BMI, HbA1c, TG, TC, HDL-C, LDL-C, smoking, or hypertension.

Abstract
BACKGROUND Numerous studies have revealed that diet has been considered as an important pathogenic factor for nonalcoholic fatty liver disease (NAFLD). The Index of Nutritional Quality (INQ) is a method of quantitative and qualitative evaluation of single foods and diets, which has special significance in recognizing clinical nutritional problems. MATERIALS AND METHODS This study included 295 patients with NAFLD and 704 controls. The dietary intake was assessed through a valid and reliable food frequency questionnaire. INQ was calculated from the questionnaire data and was compared between the 2 groups. RESULTS The controls had higher INQ of vitamin D, vitamin E, thiamin, riboflavin, niacin, vitamin B12; biotin, pantothenic acid, magnesium and zinc compared to the patients with NAFLD. After controlling for several covariates, positive associations were observed between NAFLD risk and INQs of riboflavin (ORriboflavin = 0.49, 95% confidence interval [CI]: 0.28-0.78; ORbiotin = 0.35, 95% CI: 0.18-0.76; ORpantothenic = 0.28, 95% CI: 0.12-0.64; ORmagnesium = 0.28, 95% CI: 0.11-0.75; ORzinc = 0.15 95% CI: 0.05-0.42). CONCLUSIONS Findings of the present study suggest that subjects who follow a more healthy and nutrient-rich diet, especially in terms of vitamins D, B1, B2, B12, B3 and zinc, are at a lower risk of NAFLD compared to those who consume unhealthy and nutrient-poor diet.

Abstract
Introduction: Cardiovascular disease (CVD) accounts as a major cause of mortality among patients with nonalcoholic fatty liver disease (NAFLD). Resveratrol, a natural polyphenol compound, is known for its antioxidant and antiatherogenic properties and is purported to be beneficial in decreasing CVD risk factors in NAFLD patients. Objectives: This study aimed to investigate the effects of resveratrol on atherogenic risk factors in patients with NAFLD. Methods: This randomized, double-blind, placebo-controlled clinical trial was performed on 50 patients with NAFLD aged 20-60 years. Subjects were randomly assigned to receive a daily dose of 600 mg resveratrol (n = 25) or placebo (n = 25) for 12 wk. Serum liver enzymes, lipid profile and atherogenic indices, blood pressure and anthropometric values were assessed pre and post-treatment. Results: Resveratrol supplementation reduced body weight (from 88.75 ± 11.41 to 87.54 ± 11.18 kg, P = 0.005) and BMI (from 31.00 ± 3.16 to 30.60 ± 3.26 kg/m², P = 0.01) significantly compared to the placebo group. A significant reduction in waist circumference was observed within resveratrol group (from 102.70 ± 7.68 to 101.39 ± 7.62 cm, P = 0.02). There were no significant changes in lipid profile (ox-LDL, ApoA1 and ApoB), serum atherogenic indices (LDL-C/HDL-C, ApoB/ApoA1, ox-LDL/ApoB, LDL-C/ox-LDL and AIP), liver enzymes (AST, ALT, ALP and GGT), hip circumference, waist-to-hip ratio and blood pressure in either group (P > 0.05 for all). Conclusion: These findings indicated that resveratrol supplementation in dose and duration used in this study did not affect most of the CVD risk factors in NAFLD patients. Further studies are warranted to explain more effects of resveratrol on CVD complications of NAFLD. Registration ID in IRCT: IRCT201511233664N16.
