Background/AimsDespite sexual function making an important contribution to the quality of life, data on erectile function are relatively scant in patients with chronic liver disease. We evaluated the prevalence of and risk factors for erectile dysfunction (ED) in patients with liver disease related to hepatitis B, especially among those with chronic hepatitis B (CHB) or early-stage cirrhosis.MethodsIn total, 69 patients (35 with CHB and 34 with hepatitis-B-related liver cirrhosis [HBV-LC]) aged 40-59 years were analyzed. Child-Pugh classes of A and B were present in 30 (88.2%) and 4 (11.8%) of the patients with HBV-LC, respectively. The erectile function of the patients was evaluated using the Korean version of IIEF-5.ResultsThe prevalence of any ED was 24.6% for all patients, and 8.6% and 41.2% for those with CHB and HBV-LC, respectively (P=0.002). While there was only one (2.9%) CHB patient for each stage of ED, mild, moderate, and severe ED stages were seen in three (8.8%), one (2.9%), and ten (29.4%) of the HBV-LC patients, respectively. Multiple regression analysis identified the type of liver disease (P=0.010), hypertension (P=0.022), score on the Beck Depression Inventory (P =0.044), and the serum albumin level (P=0.014) as significant independent factors for the presence of ED.ConclusionsThe prevalence of ED was significantly higher in patients with early-stage HBV-LC than in those with CHB. Therefore, screening male patients with early viral cirrhosis for ED and providing appropriate support are needed, especially when the cirrhosis is accompanied by hypertension, depression, or a depressed level of serum albumin.

Closer monitoring and active treatments must be provided to patients with risk factors for early local recurrence of HCC.

TEA Domain Transcription Factors (TEADs) are important in development and serve essential roles in tumorigenesis; however, the role of TEAD2 expression in hepatocellular carcinoma (HCC) has not been widely examined. The present study was conducted to investigate the expression status of TEAD2 in HCC and to evaluate whether the expression of TEAD2 is associated with the prognosis of patients with HCC. mRNA expression data was retrieved for Hippo pathway genes of 50 normal control and 377 HCC samples from The Cancer Genome Atlas data portal. Gene set enrichment, GeneNeighbors, ClassNeighbors and survival analyses were then performed based on the gene expression levels. The mRNA expression of TEAD2 and VGLL4 was significantly higher in HCC compared with the normal control samples, and the mRNA expression of TEAD2 was higher in advanced stages than in early stages. Specifically, survival analysis revealed that higher mRNA expression of TEAD2 was significantly associated with a less favorable overall survival rate (P= 0.0067) and there was a trend towards significance between higher mRNA expression of VGLL4 and poor overall survival rate (P=0.051). According to the gene set enrichment analysis, patients with higher mRNA expression of TEAD2 and VGLL4 had strongly enhanced epithelial-mesenchymal transition and angiogenesis, which are associated with tumor progression. In conclusion, increased mRNA expression of TEAD2 is associated with a poor prognosis in patients with HCC. TEAD2 may serve as a prognostic factor for HCC and a novel therapeutic target.

Introduction: Although signet ring cell carcinoma (SRC) is a poorly differentiated cancer subtype, recent studies suggest that endoscopic resection can be applied in small, mucosal early gastric SRC. However, other studies report frequent positive lines at the lateral resection margin after endoscopic treatment. Subepithelial spread beneath normal mucosa can exist in SRC, and such lesions may be the cause of positive margins after endoscopic resection. Thus, we conducted a retrospective study in order to evaluate the significance of subepithelial spread in early gastric SRC. Method: Medical records of early gastric SRC patients who underwent surgery or endoscopic resection from January 2011 to December 2016 at a single tertiary hospital (Daejeon, South Korea) were reviewed to examine subepithelial spread and clinical datum. Two expert pathologists reviewed all pathologic specimens, and only patients showing a pure SRC component were included. Results: Eighty-six patients were initially enrolled, and subepithelial spread existed in 62 patients (72.1%). The mean distance of subepithelial spread was 1,132.1 µm, and the maximal distance was 6,000 μm. Only discoloration was significantly associated with the presence of a subepithelial spread (p < 0.05, χ2 test, and logistic regression test). Distance of subepithelial spread did not correlate with total lesion size. Conclusion: Subepithelial spread of early gastric SRC occurs frequently and can reach up to 6 mm. Lesion discoloration may be associated with the presence of subepithelial spread. Our results suggest that careful decision of the margin is needed when performing endoscopic resection of early gastric SRC.

Background/Aims: Current evidence suggests that liver cirrhosis (LC) causes severe psychological stress and depression, which are risk factors for suicide. Although previous studies reported the association between LC and suicidal thoughts, little is known of its effect on suicidal deaths. Therefore, this study was undertaken to investigate the effect of new-onset LC on suicide.Methods: From the National Health Insurance Service-National Sample Cohort of South Korea, 5,809 incident LC patients and 11,618 risk-set controls matched by propensity score were selected for follow-up. The incidence rate of suicide was estimated using a generalized estimating equation with a Poisson distribution. Effect size was presented as a hazard ratio (HR) using Cox’s proportional hazards model.Results: The incidence rate of suicide was 143.3 cases per 100,000 person years (95% confidence interval [CI], 100.2–205.1) among the LC cohort. The LC patients were 2.37 times more likely to commit suicide compared with matched controls (HR, 2.37; 95% CI, 1.44–3.88). Increased suicide risk was evident within the first 2 years of the follow-up period (HR, 2.59; 95% CI, 1.20–5.60) and among the 18–49-year-old age group (HR, 3.72; 95% CI, 1.45–9.56).Conclusions: Our study found increased risk of suicide in patients with new onset LC, especially during the early period following diagnosis and in younger patients. To decrease this suicide risk, a regular and continuous social support system is required.

The risk of developing hepatocellular carcinoma (HCC) after hepatitis B e antigen seroclearance (ESC) remains unclear. We established and validated a new risk prediction model for HCC development after ESC in patients with chronic hepatitis B (CHB) receiving antiviral therapy (AVT). Between 2006 and 2016, 769 patients (training cohort) and 1,061 patients (validation cohort) with CHB who experienced ESC during AVT using entecavir (ETV) or tenofovir disoproxil fumarate (TDF) were recruited. In the multivariate analysis, male sex (hazard ratio [HR] = 2.092; 95% confidence interval [CI] = 1.152‐3.800), cirrhosis (HR = 5.141; 95% CI = 2.367‐11.167) and fibrosis‐4 index (FIB‐4) of >3.25 (HR = 2.070; 95% CI = 1.184‐3.620) were the independent risk factors for HCC development (all P < .05). Accordingly, a novel HCC‐ESCAVT model was developed (1x[sex: male = 1, female = 0] + 3x(cirrhosis = 1, noncirrhosis = 0) + 1x(FIB‐4: >3.25 = 1, ≤3.25 = 0). The cumulative risk for HCC development was significantly different among the risk groups based on the HCC‐ESCAVT category (0‐1, 2‐4 and 5 for the low‐, intermediate‐ and high‐risk groups, respectively) (overall P < .001, log‐rank test). The area under the receiver operating characteristic curve (AUC) for predicting HCC development 3, 5 and 10 years after ESC was 0.791, 0.771 and 0.790, respectively (all P < .05). The predictive value of the HCC‐ESCAVT model was similar in the validation cohort (AUC = 0.802, 0.774 and 0.776 at 3, 5 and 10 years, respectively; all P < .05). Hence, we have developed and validated a new HCC‐ESCAVT model for HCC development, which includes male sex, cirrhosis and FIB‐4 of >3.25 as constituent variables.
