Hepatitis B virus (HBV) infection is the most common cause of chronic liver diseases in Korea. After the introduction of the universal HBV vaccination program, the prevalence of hepatitis B surface antigen was markedly reduced, and Korea is now classified as an area of intermediate endemicity for HBV. However, there are still hurdles for elimination of hepatitis B, such as immunoprophylaxis failure against vertical transmission, occurrence of acute hepatitis B among peoples who did not have vacc

Circulating microbial dysbiosis is associated with chronic liver disease including nonalcoholic steatohepatitis and alcoholic liver disease. In this study, we evaluated whether disease-specific alterations of circulating microbiome are present in patients with cirrhosis and hepatocellular carcinoma (HCC), and their potential as diagnostic biomarkers for HCC. We performed cross-sectional metagenomic analyses of serum samples from 79 patients with HCC, 83 with cirrhosis, and 201 matching healthy c

BACKGROUND AND AIMS: We investigated the relative etiological role of prior hepatitis B virus (HBV) infection and nonalcoholic fatty liver disease (NAFLD) in the development of non-B non-C, non-alcohol or specific cause-related hepatocellular carcinoma (NBNC-NA-NS HCC) in an HBV-endemic area of Korea. METHODS: A total of 329 patients with NBNC-NA-NS HCC were enrolled in this study. Prior HBV infection was defined as the presence of isolated IgG hepatitis B core antibody (anti-HBc), and NAFLD was

Nonalcoholic fatty liver disease (NAFLD) is increasing worldwide, highlighting the importance of early and accurate detection and the appropriate management of NAFLD. However, ultrasonography (US) is not included in many mass screening programs, and people have limited access to it. The aim of this study is to validate the fatty liver index (FLI) and investigate the optimal cutoff value for predicting NAFLD in an asymptomatic population. We conducted a retrospective cohort study in Korea. All su

Fibulin-3, an extracellular glycoprotein, has been suggested as having functions in tissue regeneration and organogenesis. However, its role in cancer remains unclear. We show here that fibulin-3 was silenced by hypermethylation of the promoter region in the relatively invasive A549 non-small cell lung cancer (NSCLC) cells compared with less invasive H460 NSCLC cells. Enforced expression of fibulin-3 in A549 cells down-regulated cellular MMP-7 and MMP-2, which was followed by inhibition of cell

Portal hypertension is a direct consequence of hepatic fibrosis, and several hepatic fibrosis markers have been evaluated as a noninvasive alternative to the detection of portal hypertension and esophageal varices. In the present study, we compared the diagnostic and prognostic values of the noninvasive fibrosis markers in patients with alcoholic cirrhosis. A total of 219 consecutive alcoholic cirrhosis patients were included. Biochemical scores and liver stiffness (LS) were compared with hepati

Protein disulfide isomerase (PDI) is a thiodisulfide oxidoreductase that catalyzes the formation, reduction and rearrangement of disulfide bonds in proteins of eukaryotes. The classical PDI has a signal peptide, two CXXC-containing thioredoxin catalytic sites (a,a'), two noncatalytic thioredoxin fold domains (b,b'), an acidic domain (c) and a C-terminal endoplasmic reticulum (ER) retention signal. Although PDI resides in the ER where it mediates the folding of nascent polypeptides of the secreto

Population-based data regarding the prognostic implication of gamma-glutamyl transferase (GGT) have been inconsistent. We examined the association of GGT with all-cause and disease-specific mortality. Using the Korean nationwide database, we included 9,687,066 subjects without viral hepatitis or cirrhosis who underwent a health examination in 2009. Subjects were classified into three groups by sex-specific tertile of serum GGT levels. The underlying causes of death were classified by 10th Revisi

BACKGROUND & AIMS: Liver enzymes, such as alanine aminotransferase (ALT), aspartate aminotransferase (AST) and γ-glutamyltransferase (GGT), have been suggested as surrogate markers of various cardiovascular diseases. However, previous studies assessed liver enzymes only once at baseline. We investigated the association between liver enzyme variability and the risk of mortality and cardiovascular outcomes in general population. METHODS: A total of 6 496 271 subjects participating in ≥3 health exa

Liver cirrhosis and hepatocellular carcinoma (HCC) are serious late complications that can occur after the Fontan procedure. This study aimed to investigate the cumulative incidence of cirrhosis and HCC and to identify specific features distinguishing HCC from benign arterial-phase hyperenhancing (APHE) nodules that developed after the Fontan operation. We retrospectively enrolled 313 post-Fontan patients who had been followed for more than 5 years and had undergone ultrasound or computed tomogr

PURPOSE: To provide basic data to improve the practice environment of pediatric nurses by identifying their recognition of nursing professionalism and self-efficacy, and to examine the pediatric nurse parent partnership.METHODS: Participants in the study were 165 nurses with 6 months of work experience in a university children's hospital in Seoul. Data were collected using a self-report questionnaire. Research tools measuring nursing professionalism, self-efficacy, and pediatric nurse parent par

PURPOSE: Insulin-like growth factor-I (IGF-I) reflects hepatic synthetic function and plays an important role in the development and progression of various cancers. In this study, we investigated whether pretreatment serum IGF-I levels predict time-to-recurrence (TTR) and overall survival (OS) in patients with early-stage hepatocellular carcinoma after curative treatment. EXPERIMENTAL DESIGN: Consecutive patients with hepatocellular carcinoma who had undergone surgical resection, radiofrequency
