The PKHD1 gene inhibits tumor proliferation and invasion in intrahepatic cholangiocarcinoma by activating the Notch pathway.

Intrahepatic cholangiocarcinoma (ICC), one type of highly malignant tumor, has a poor prognosis. However, the specific role of the polycystic kidney and hepatic disease 1 (PKHD1) gene in ICC has not yet been evaluated. This study aimed to investigate the potential function and mechanism of the PKHD1 gene in ICC.

Serum uric acid levels and prognosis of patients with non-alcoholic fatty liver disease.

Uric acid (UA) is associated with non-alcoholic fatty liver disease (NAFLD). However, it is unclear whether UA plays a predictive role in NAFLD prognosis. This study aimed to explore the relationship between UA levels and mortality in NAFLD patients without severe renal disease.

The prognostic role of diet quality in patients with MAFLD and physical activity: data from NHANES.

Background And Objectives: Dietary control and increased physical activity (PA) are recommended for patients with metabolic (dysfunction-) associated fatty liver disease (MAFLD). However, not all patients can sustain both exercise and a healthy diet. This study explored the interaction between dietary quality, PA levels, and mortality in MAFLD patients.

Evaluating the global, regional, and national impact of syphilis: results from the global burden of disease study 2019.

Syphilis is a global public health concern. This study aimed to assess the global and regional burden of syphilis from 1990 to 2019. Disease burden was evaluated using disability-adjusted life-years (DALYs) and prevalence.

The association between serum 25-hydroxyvitamin D and the prevalence of herpes simplex virus.

Previous studies have reported a potential anti-infection effect for vitamin D. However, the relationship between vitamin D status and herpes simplex virus (HSV) infection has not yet been evaluated. Therefore, this study aimed to determine the association between serum 25-hydroxyvitamin D [25(OH)D] and infection with HSV types 1 and 2 (HSV-1 and HSV-2).

Serum high-sensitive C-reactive protein is a simple indicator for all-cause among individuals with MAFLD.

High-sensitive C-reactive protein (hs-CRP) is one of the diagnostic components for metabolic (-dysfunction) associated fatty liver disease (MAFLD). This study aimed to explore the relationship between hs-CRP level and 25-year mortality in patients with MAFLD. The study data were from the Third National Health and Nutrition Examination Survey 1988-1994.

Fatty liver disease reverses the obesity paradox in chronic kidney disease stages 3-5: A follow-up study of NHANES III.

High body mass index (BMI) has been associated with better survival in patients with end-stage kidney disease. Individuals with fatty liver disease (FLD) have a higher risk of chronic kidney disease. It remains unclear whether the survival benefit of high BMI in patients with chronic kidney disease is present when there is concomitant FLD.

Validation of Non-invasive Fibrosis Scores for Predicting Advanced Fibrosis in Metabolic-associated Fatty Liver Disease.

Background And Aims: Metabolic-associated fatty liver disease (MAFLD) is a newly proposed terminology from 2020; yet, the applicability of conventional noninvasive fibrosis models is still unknown for it. We aimed to evaluate the performance of conventional noninvasive fibrosis scores in MAFLD.

Methods: The NHANES 2017-2018 datasets were used to compare the performances of different noninvasive fibrosis scores in MAFLD, including the aspartate aminotransferase (AST) to platelet ratio index (APRI), body mass index (BMI)-AST/alanine aminotransferase (ALT) ratio and diabetes score (BARD), fibrosis-4 index (FIB-4), and NAFLD fibrosis score (NFS).

The global disease burden of varicella-zoster virus infection from 1990 to 2019.

Data on the global epidemiology of varicella-zoster virus infection (VZVI) is limited. This study aimed to investigate the burden of VZVI based on the global burden of disease study 2019 data. The age-standardized rates, including the incidence, death, disability-adjusted life years (DALYs), and the estimated annual percentage changes (EAPC) of VZVI were calculated to evaluate the disease burden of VZVI.

Validation of conventional non-invasive fibrosis scoring systems in patients with metabolic associated fatty liver disease.

Background: Non-invasive fibrosis scores are not yet validated in the newly defined metabolic associated fatty liver disease (MAFLD).

Aim: To evaluate the diagnostic performance of four non-invasive scores including aspartate aminotransferase to platelet ratio index (APRI), fibrosis-4 index (FIB-4), body mass index, aspartate aminotransferase/alanine aminotransferase ratio, diabetes score (BARD), and nonalcoholic fatty liver disease fibrosis score (NFS) in patients with MAFLD.

Methods: Consecutive patients with histologically confirmed MAFLD were included.

MAFLD Criteria May Overlook a Subtype of Patient with Steatohepatitis and Significant Fibrosis.

Introduction: Metabolic associated fatty liver disease (MAFLD) is a novel concept for fatty liver disease. Different from non-alcoholic fatty liver disease (NAFLD), the diagnosis of MAFLD requires the presence of metabolic risks. This study aimed to characterize patients with liver steatosis but without metabolic risks (non-MR-steatosis) which may not be diagnosed by MAFLD criteria.

[Retracted] Anticancer and apoptotic activities of oleanolic acid are mediated through cell cycle arrest and disruption of mitochondrial membrane potential in HepG2 human hepatocellular carcinoma cells.

Following the publication of the above paper, a concerned reader drew to the Editor's attention that several figures (principally, Figs. 3, 6 and 8) contained data that bore striking similarities to data published in other papers, some of which had been published around the same time and written by different authors based at different research institutions. After having conducted an independent investigation in the Editorial Office, the Editor of has determined that this article should be retracted from the Journal on account of a lack of confidence concerning the originality and the authenticity of the data.

MAFLD Criteria Guide the Subtyping of Patients with Fatty Liver Disease.

Background And Aims: Metabolic associated fatty liver disease (MAFLD) is diagnosed in patients with hepatic steatosis when they have the following three metabolic conditions: obesity/overweight, diabetes and metabolic dysregulation, either alone or in combination. There is no clarity whether subtypes of MAFLD diagnosed by different metabolic conditions carry different levels of risk for intra- and extra-hepatic organs. This study aims to depict the characteristics of these subtypes in a large population.

Clinic-pathological features of metabolic associated fatty liver disease with hepatitis B virus infection.

Background: Metabolic associated fatty liver disease (MAFLD) is a novel concept proposed in 2020.

Aim: To compare the characteristics of MAFLD and MAFLD with hepatitis B virus (HBV) infection.

Methods: Patients with histopathologically proven MAFLD from a single medical center were included.

Concurrence of HBV infection and non-alcoholic fatty liver disease is associated with higher prevalence of chronic kidney disease.

Aims: Coexistence of non-alcoholic fatty liver disease (NAFLD) and hepatitis B virus (HBV) infection is common in clinical practice. This study was to explore the prevalence of chronic kidney disease (CKD) in patients with NAFLD and/or HBV.

Methods: Participants who received health examination in a physical examination center were included in this cross-sectional study.

Comparison of MAFLD and NAFLD diagnostic criteria in real world.

This meta-analysis aimed to explore the risk of severe COVID-19 in patients with pre-existing chronic obstructive pulmonary disease (COPD) and ongoing smoking history. A comprehensive systematic literature search was carried out to find studies published from December 2019 to 22 March 2020 from five databases.

COVID-19 in posttransplant patients-report of 2 cases.

Coronavirus Disease 2019 (COVID-19) has become a pandemic since March 2020. We describe here 2 cases of COVID-19 infection in a posttransplant setting. First one is a 59-year-old renal transplant recipient; the second is a 51-year-old allogeneic bone marrow transplant recipient.

Procalcitonin and Liver Disease: A Literature Review.

Procalcitonin (PCT) is a widely used biomarker for the diagnosis of bacterial infections. It is produced by various organs and the liver is considered to be the most important site of production. Severe liver dysfunction has been shown to influence PCT levels.
