Objective: To explore the correlation between alanine aminotransferase (ALT) trajectories and new-onset metabolic fatty liver disease (MAFLD) to provide a scientific basis for the prevention and treatment of MAFLD. Methods: The study cohort was composed of 3 553 subjects who met the inclusion criteria in the cohort study of the Henan physical examination population. According to the ALT levels of the subjects' physical examination from 2017-2019, three different ALT trajectory groups were determined by R LCTMtools, namely low-stable group, medium-stable group, and high-stable group. The incidence of MAFLD during physical examination in 2020 was followed up, the cumulative incidence rate in each group was calculated by product-limit method, and Cox proportional hazards regression model analyzed the correlation between different ALT trajectories and new-onset MAFLD. Results: The incidence rate of MAFLD parallelly increased with the increase of ALT locus, which was 6.93%, 15.42%, and 19.05%, respectively, and the difference was statistically significant (P<0.001). After adjusting for multiple confounding factors, such as gender, waist circumference, blood pressure, BMI, fasting blood sugar, and blood lipid by Cox proportional hazards regression model, the risks of MAFLD in ALT medium-stable and the high-stable group were still 1.422 times (95%CI:1.115-1.813) and 1.483 times (95%CI:1.040-2.114) of low-stable ALT group (P<0.05). Conclusions: The risk of MAFLD parallelly increases with the increase of ALT level in the normal long-term range. it is necessary to carry out the intervention for MAFLD with long-term average high value to avoid the progress of MAFLD disease to achieve the early prevention on MAFLD.

OBJECTIVE: This study aimed to develop an artificial neural network (ANN) model combined with dietary retinol intake from different sources to predict the risk of non-alcoholic fatty liver disease (NAFLD) in American adults. METHODS: Data from the 2007 to 2014 National Health and Nutrition Examination Survey (NHANES) 2007-2014 were analyzed. Eligible subjects ( n = 6,613) were randomly divided into a training set ( n ₁ = 4,609) and a validation set ( n ₂ = 2,004) at a ratio of 7:3. The training set was used to identify predictors of NAFLD risk using logistic regression analysis. An ANN was established to predict the NAFLD risk using a training set. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the accuracy of the model using the training and validation sets. RESULTS: Our study found that the odds ratios ( ORs) and 95% confidence intervals ( CIs) of NAFLD for the highest quartile of plant-derived dietary retinol intake (i.e., provitamin A carotenoids, such as β-carotene) ( OR = 0.75, 95% CI: 0.57 to 0.99) were inversely associated with NAFLD risk, compared to the lowest quartile of intake, after adjusting for potential confounders. The areas under the ROC curves were 0.874 and 0.883 for the training and validation sets, respectively. NAFLD occurs when its incidence probability is greater than 0.388. CONCLUSION The ANN model combined with plant-derived dietary retinol intake showed a significant effect on NAFLD. This could be applied to predict NAFLD risk in the American adult population when government departments formulate future health plans.

The rising prevalence of nonalcoholic fatty liver disease (NAFLD) is now the second largest indication for liver transplantation in Western countries, but viral hepatitis B and end-stage alcohol-related liver disease are still the main indications in China. With the improvement of people's living standards, the prevalence of metabolic syndrome, and the number of NAFLD patients has also gradually increased. At the same time, with the hepatitis B vaccination popularization and the nucleos(t)ide analogues and other drugs uses, it is predicted that NAFLD-related end-stage liver disease may become one of the main indications for liver transplantation in our country in the future. This article reviews the research progress of NAFLD and liver transplantation.
