The effect of prebiotic and probiotic food consumption on anxiety severity: a nationwide study in Korea.

Objectives: Over the past decade, research has reported that diet and gut health affect anxiety symptoms through changes in the gut microbiota. Therefore, the introduction of prebiotic and probiotic food favorable for the intestinal microbiota is necessary to improve the mental health of the host. The purpose of this study was to examine the contribution of prebiotic and probiotic foods to lowering anxiety symptoms using a large, nationwide population-based database. Materials and methods: The study population included 4,317 individuals 19 to 64 years of age who participated in the Korean National Health and Nutrition Examination Survey (KNHANES VII-3, 2019-2021). A food frequency questionnaire was used to evaluate prebiotic and probiotic food consumption. The Generalized Anxiety Disorder Assessment 7-item scale (GAD-7) assessed the severity of anxiety symptoms. The effect of prebiotic and probiotic food consumption on anxiety severity was analyzed using multiple logistic regression. Results: Anxiety symptom severity was significantly lower in the highest prebiotic and/or probiotic food consumption tertiles compared to the lowest food consumption tertile. We also found a sex difference in the odds ratio for anxiety symptoms. The consumption of prebiotic food was significantly associated with the highest odds of anxiety among both men and women. However, probiotic food had a significant beneficial effect on lowering anxiety symptoms in men but not in women. Conclusion: Our finding suggests that prebiotic and probiotic food consumption might confer a beneficial influence on anxiety symptoms. Further research is required for a deeper understanding into the mechanisms of the positive effects of prebiotics and probiotics on anxiety.

Association between Atherosclerosis and High-Risk Colorectal Adenomas based on Cardio-Ankle Vascular Index and Ankle-Brachial Index.

Background/Aims: Colorectal adenomas are precancerous lesions that may lead to colorectal cancer. Recent studies have shown that colorectal adenomas are associated with atherosclerosis. The cardio-ankle vascular index (CAVI) and ankle-brachial index (ABI) are noninvasive methods for evaluating atherosclerosis. This study examined the association between atherosclerosis and high-risk colorectal adenomas based on the CAVI and ABI. Methods: The data of patients aged ≥50 years who had a colonoscopy and CAVI and ABI measurements from August 2015 to December 2021 at the Kangwon National University Hospital were analyzed retrospectively. After the colonoscopy, subjects were divided into no, overall, and high-risk (size ≥1 cm, high-grade dysplasia or villous adenoma, three or more adenomas) adenoma groups based on the pathology findings. The data were subjected to univariate and multivariate logistic regression analyses. Results: Among the 1,164 subjects, adenomas and high-risk adenomas were found in 613 (52.6%) and 118 (10.1%) patients, respectively. The rate of positive ABI (<0.9) and positive CAVI (≥9.0) were significantly higher in the high-risk adenoma group (22.0% and 55.9%) than in the no adenoma (12.3% and 39.6%) and the overall adenoma group (15.7% and 44.0%) (p=0.008 and p=0.006, respectively). Multivariate analysis revealed a positive CAVI and smoking status to be significantly associated with high-risk adenoma with an odds ratio of 1.595 (95% confidence interval 1.055-2.410, p=0.027) and 1.579 (1.072-2.324, p=0.021), respectively. Conclusions: In this study, a significant correlation between positive CAVI and high-risk adenomas was observed. Therefore, CAVI may be a significant predictor for high-risk colorectal adenoma.

A Deep Learning Driven Simulation Analysis of the Emotional Profiles of Depression Based on Facial Expression Dynamics.

Objective: : Diagnosis and assessment of depression rely on scoring systems based on questionnaires, either self-reported by patients or administered by clinicians, and observation of patient facial expressions during the interviews plays a crucial role in making impressions in clinical settings. Deep learning driven approaches can assist clinicians in the course of diagnosis of depression by recognizing subtle facial expressions and emotions in depression patients. Methods: : Seventeen simulated patients who acted as depressed patients participated in this study. A trained psychiatrist structurally interviewed each participant with moderate depression in accordance with a prepared scenario and without depressive features. Interviews were video-recorded, and a facial emotion recognition algorithm was used to classify emotions of each frame. Results: : Among seven emotions (anger, disgust, fear, happiness, neutral, sadness, and surprise), sadness was expressed in a higher proportion on average in the depression-simulated group compared to the normal group. Neutral and fear were expressed in higher proportions on average in the normal group compared to the normal group. The overall distribution of emotions between the two groups was significantly different (p ＜ 0.001). Variance in emotion was significantly less in the depression-simulated group (p ＜ 0.05). Conclusion: : This study suggests a novel and practical approach to understand the emotional expression of depression patients based on deep learning techniques. Further research would allow us to obtain more perspectives on the emotional profiles of clinical patients, potentially providing helpful insights in making diagnosis of depression patients.

COVID-19 vaccine acceptance and related behavioral and psychological characteristics in individuals with mental disorders in Korea.

Objective: This study aimed to investigate COVID-19 vaccine acceptance and related factors in individuals with mental disorders in Korea. Methods: We surveyed 572 individuals with mental disorders about their attitudes toward COVID-19 vaccination using a 7-item self-rating questionnaire on vaccine acceptance and hesitancy. We categorized the respondents into groups based on their level of vaccine acceptance using hierarchical clustering. In addition, we evaluated the respondents' vaccination status and trust in sources of information regarding COVID-19 vaccines, and assessed their psychological characteristics using the Patient Health Questionnaire-9, Gratitude Questionnaire-6, and Big Five Inventory-10. Results: Clustering revealed three groups according to vaccine acceptance: 'totally accepting' (n= 246, 43.0%), 'somewhat accepting' (n= 184, 32.2%), and 'hesitant' (n= 142, 24.8%) groups. Three quarters of all participants, who belonged to the 'totally accepting' or 'somewhat accepting' groups, were willing to receive a COVID-19 vaccine despite concerns about its side effects. Individuals in the high vaccine acceptance group were older (F= 12.52, p< 0.001), more likely to receive the influenza vaccine regularly, and more likely to trust formal information sources. Additionally, they had higher levels of gratitude (F= 21.00, p< 0.001) and agreeableness (F= 4.50, p= 0.011), and lower levels of depression (χ2= 11.81, p= 0.003) and neuroticism (F= 3.71, p= 0.025). Conclusion: The present study demonstrated that individuals with mental disorders were generally willing to receive COVID-19 vaccination. However, they weighed its need and effectiveness against potential side effects before coming to a decision. It is important to understand the behavioral and psychological characteristics associated with vaccine acceptance, to effectively communicate its importance to individuals with mental disorders.

Outcome of Intermittent Thoracentesis versus Pigtail Catheter Drainage for Hepatic Hydrothorax.

Background/Aims: The management of hepatic hydrothorax (HH) remains a challenging clinical scenario with suboptimal options. We investigated the effect and safety of pigtail catheter drainage compared to intermittent thoracentesis. Methods: This multicenter, retrospective study included 164 cirrhotic patients with recurrent pleural effusion from March 2012 to June 2017. Patients with neoplasms, cardiopulmonary disease, and infectious conditions were excluded. We compared the clinical outcomes of pigtail catheter drainage versus thoracentesis for variables including complications related to procedures, overall survival, and re-admission rates. Results: A total of 164 patients were divided into pigtail catheter (n = 115) and thoracentesis (n = 49) groups. During the follow-up period of 6.93 months after discharge, 98 patients died (pigtail; n = 47 vs. thoracentesis; n = 51). The overall survival (p = 0.61) and 30-day mortality (p = 0.77) rates were similar between the pigtail catheter and thoracentesis groups. Only MELD scores were associated with overall survival (adjusted HR, 1.08; p < 0.01) in patients with HH. Spontaneous pleurodesis occurred in 59 patients (51.3%) in the pigtail catheter group. Re-admission rates did not differ between the pigtail catheter and thoracentesis groups (13.2% vs 19.6% p = 0.7). A total of five complications occurred, including four total cases of bleeding (one patient in the pigtail catheter group and three in the thoracentesis group) and one case of empyema in the pigtail catheter group. Conclusions: Pigtail catheter drainage is not inferior to that of intermittent thoracentesis for the management of HH, proving it may be an effective and safe clinical option.

Functional Characterization of Endothelial Cells Differentiated from Porcine Epiblast Stem Cells.

Endothelial cells (ECs), lining blood vessels' lumen, play an essential role in regulating vascular functions. As multifunctional components of vascular structures, pluripotent stem cells (PSCs) are the promising source for potential therapeutic applications in various vascular diseases. Our laboratory has previously established an approach for differentiating porcine epiblast stem cells (pEpiSCs) into ECs, representing an alternative and potentially superior cell source. However, the condition of pEpiSCs-derived ECs growth has yet to be determined, and whether pEpiSCs differentiate into functional ECs remained unclear. Changes in morphology, proliferation and functional endothelial marker were assessed in pEpiSCs-derived ECs in vitro. pEpiSCs-derived ECs were subjected to magnetic-activated cell sorting (MACS) to collect CD-31+ of ECs. We found that sorted ECs showed the highest proliferation rate in differentiation media in primary culture and M199 media in the subculture. Next, sorted ECs were examined for their ability to act as typical vascular ECs through capillary-like structure formation assay, Dil-acetylated low-density lipoprotein (Dil-Ac-LDL) uptake, and three-dimensional spheroid sprouting. Consequently, pEpiSCs-derived ECs function as typical vascular ECs, indicating that pEpiSC-derived ECs might be used to develop cell therapeutics for vascular disease.

Reappraisal of sepsis-3 and CLIF-SOFA as predictors of mortality in patients with cirrhosis and infection presenting to the emergency department: A multicenter study.

BACKGROUND/AIMS: Sepsis-3 criteria and quick Sequential Organ Failure Assessment (qSOFA) have been advocated to be used in defining sepsis in the general population. We aimed to compare the Sepsis-3 criteria and Chronic Liver Failure-SOFA (CLIF-SOFA) scores as predictors of in-hospital mortality in cirrhotic patients admitted to the emergency department (ED) for infections. METHODS: A total of 1,622 cirrhosis patients admitted at the ED for infections were assessed retrospectively. We analyzed their demographic, laboratory, and microbiological data upon diagnosis of the infection. The primary endpoint was inhospital mortality rate. The predictive performances of baseline CLIF-SOFA, Sepsis-3, and qSOFA scores for in-hospital mortality were evaluated. RESULTS: The CLIF-SOFA score proved to be significantly better in predicting in-hospital mortality (area under the receiver operating characteristic curve [AUROC], 0.80; 95% confidence interval [CI], 0.78-0.82) than the Sepsis-3 (AUROC, 0.75; 95% CI, 0.72-0.77, P<0.001) and qSOFA (AUROC, 0.67; 95% CI, 0.64-0.70; P<0.001) score. The CLIF-SOFA, CLIF-C-AD scores, Sepsis-3 criteria, septic shock, and qSOFA positivity were significantly associated with in-hospital mortality (adjusted hazard ratio [aHR], 1.24; 95% CI, 1.19-1.28; aHR, 1.13; 95% CI, 1.09-1.17; aHR, 1.19; 95% CI, 1.15-1.24; aHR, 1.88; 95% CI, 1.42-2.48; aHR, 2.06; 95% CI, 1.55-2.72; respectively; all P<0.001). For CLIF-SOFA scores ≥6, in-hospital mortality was >10%; this is the cutoff point for the definition of sepsis. CONCLUSION: Among cirrhosis patients presenting with infections at the ED, CLIF-SOFA scores showed a better predictive performance for mortality than both Sepsis-3 criteria and qSOFA scores, and can be a useful tool of risk stratification in cirrhotic patients requiring timely intervention for infection.

Decreased Health-Seeking Behaviors in People With Depressive Symptoms: The Korea National Health and Nutrition Examination Survey 2014, 2016, and 2018.

OBJECTIVE: The purpose of this study was to investigate the effects of depressive symptoms on health-seeking behaviors using the large epidemiological study data of the Korea National Health and Nutrition Examination (KNHANES). METHODS: Data from the Korea National Health and Nutrition Examination Survey (KNHANES), which is a large-scale national survey, were used in this study. The Patient Health Questionnaire-9 (PHQ-9) was used to assess the depressive state of the participants. Specialized self-reported questionnaires that included questions about health-seeking behaviors were also performed. To examine the relationships between depression and health-seeking behaviors, complex sample logistic regression models with control for covariates were used. RESULTS: There was a significant association between decreased health-seeking behaviors and depressive symptoms in adults (odds ratio [OR]: 3.11, 95% confidence interval [CI]: 2.44-3.96). The association was found to be especially strong in males (OR: 2.63, 95% CI: 1.69-4.10) versus in females (OR: 2.49, 95% CI: 1.90-3.27). With regard to age group, younger adults (19-44 years of age) showed the highest OR (OR: 3.07, 95% CI: 2.12-4.45). CONCLUSION: Our findings support the idea that there is a significant association between health-seeking behaviors and depressive symptoms in the Korean population. These results suggest that individuals with decreased health-seeking behaviors could be evaluated for depressive symptoms.

Novel management of expected post-radiotherapy complications in hepatocellular carcinoma patients: a case report.

In recent years, radiotherapy (RT) has been used to treat hepatocellular carcinoma (HCC) at each stage. This clinical trend has developed with the increasing improvement of RT techniques, which show clinical results comparable to those of other treatment modalities. Intensity-modulated radiotherapy uses a high radiation dose to improve treatment effectiveness. However, the associated radiation toxicity can damage adjacent organs. Radiation-induced gastric damage with gastric ulcers is a complication of RT. This report presents a novel management strategy for preventing post-RT gastric ulcers. We present the case of a 53-year-old male patient diagnosed with HCC, who experienced gastric ulcer after RT. Before the second round of RT, the patient was administered a gas-foaming agent, which was effective in preventing RT complications.

Hypertriglyceridemia is a Risk Factor for Fever in Early Acute Non-biliary Pancreatitis.

Background/Aims: Fever is a common symptom of acute pancreatitis (AP). This study examined the factors associated with fever due to pancreatic inflammation in the early stages of non-biliary AP. Methods: This study analyzed the AP database from Kangwon National University Hospital from January 2018 until April 2021 and identified patients who developed fever within 1 week of hospitalization. Patients with gallstone pancreatitis, pseudocyst, walled-off necrosis, chronic pancreatitis, bacteremia, and other site infections were excluded. The febrile group was compared with the afebrile group. Results: One hundred and fifty-two patients were analyzed, and fever was diagnosed in 79 patients (52.0%). Based on multivariate analysis, fever was positively correlated with hypertriglyceridemia-induced AP (OR 16.8, 95% CI 4.0-70.7, p<0.01) and computed tomography severity index (OR 1.7, 95% CI 1.2-2.6, p<0.01). Recurrent AP was negatively associated with fever (OR 0.3, 95% CI 0.1-0.8, p=0.01). Fever was more frequent in patients with higher initial serum triglyceride (TG) levels than those with lower levels (TG <200 mg/dL; 35.1%, 200≤TG<500 mg/dL; 42.3%, TG ≥500 mg/dL; 88.6%, p<0.01). Conclusions: Hypertriglyceridemia and CT severity index are associated with fever in early non-biliary AP.

Metformin and Dichloroacetate Suppress Proliferation of Liver Cancer Cells by Inhibiting mTOR Complex 1.

The Warburg effect is important for cancer cell proliferation. This phenomenon can be flexible by interaction between glycolysis and mitochondrial oxidation for energy production. We aimed to investigate the anticancer effects of the pyruvate dehydrogenase kinase inhibitor, dichloroacetate (DCA) and the mitochondrial respiratory complex I inhibitor metformin in liver cancer cells. The anticancer effect of DCA and/or metformin on HepG2, PLC/PRF5 human liver cancer cell lines, MH-134 murine hepatoma cell lines, and primary normal hepatocytes using MTT assay. Inhibition of lactate/ATP production and intracellular reactive oxygen species generation by DCA and metformin was investigated. Inhibition of PI3K/Akt/mTOR complex I was evaluated to see whether it occurred through AMPK signaling. Anticancer effects of a combination treatment of DCA and metformin were evaluated in HCC murine model. The results showed that metformin and DCA effectively induced apoptosis in liver cancer cells. A combination treatment of metformin and DCA did not affect viability of primary normal hepatocytes. Metformin upregulated glycolysis in liver cancer cells, thereby increasing sensitivity to the DCA treatment. Metformin and DCA inhibited mTOR complex I signaling through upregulated AMPK-independent REDD1. In addition, metformin and DCA increased reactive oxygen species levels in liver cancer cells, which induced apoptosis. A combination treatment of metformin and DCA significantly suppressed the tumor growth of liver cancer cells using in vivo xenograft model. Taken together, the combined treatment of metformin and DCA suppressed the growth of liver cancer cells. This strategy may be effective for patients with advanced liver cancer.

The Presence or Absence of Alkaline Phosphatase Activity to Discriminate Pluripotency Characteristics in Porcine Epiblast Stem Cell-Like Cells.

Porcine embryonic stem cells (pESCs) would provide potentials for agricultural- and biotechnological-related applications. However, authentic pESCs have not been established yet because standards for porcine stem cell-specific markers and culture conditions are not clear. Therefore, the present study reports attempts to derive pluripotent epiblast stem cells either from in vitro or in vivo derived porcine embryos. Nine epiblast cell lines (seven lines from Berkshire and two lines from Duroc) could only be isolated from day 9- to 9.5-old in vivo derived early conceptuses. Pluripotency features were analyzed in relation to the presence or absence of alkaline phosphatase (AP) activity. Interestingly, the mRNA expression of several marker genes for pluripotency or epiblast was different between putative epiblast stem cells of the two groups [AP-positive (+) pEpiSC-like cell 2 line and AP-negative (-) pEpiSC-like cell 8 line]. For example, expressions of OCT-3/4, NANOG, SOX2, c-MYC, FGF2, and NODAL in AP-negative (-) porcine epiblast stem cell (pEpiSC)-like cells were higher than those in AP-positive (+) pEpiSC-like cells. Expression of surface markers differed between the two groups to some extent. SSEA-1 was strongly expressed only in AP-negative (-) pEpiSC-like cells, whereas AP-positive (+) pEpiSC-like cells did not express. In addition, we report to have some differences in the in vitro differentiation capacity between AP-positive (+) and AP-negative (-) epiblast cell lines. Primary embryonic germ layer markers (cardiac actin, nestin, and GATA 6) and primordial germ cell markers (Dazl and Vasa) were strongly expressed in embryoid bodies (EBs) aggregated from AP-negative (-) pEpiSC-like cells, whereas EBs aggregated from AP-positive (+) pEpiSCs did not show expression of primary embryonic germ layers and primordial germ cell markers except GATA 6. These results indicate that pEpiSC-like cells display different pluripotency characteristics in relation to AP activity.

The longitudinal outcomes of applying non-selective beta-blockers in portal hypertension: real-world multicenter study.

BACKGROUND/AIM: We investigated the effect of non-selective ß-blockers (NSBB) in real-world situations and whether low-dose NSBB is beneficial compared to maximally tolerated doses. METHODS: We performed a retrospective study of 740 patients with cirrhosis requiring prophylactic treatment of esophageal varices: 473 primary prophylaxis (PP: NSBB = 349, non-NSBB = 124) and 267 secondary prophylaxis (SP: NSBB = 200, non-NSBB = 67). The NSBB group was divided into low-dose (≤ 80 mg/day) and high-dose (> 80 mg/day). RESULTS: In the PP group, NSBB treatment reduced mortality and showed the most pronounced effect in patients with moderate/severe ascites (hazard ratio [HR], 0.46; p < 0.01), HVPG ≥ 16 mmHg (HR, 0.53; p = 0.04), or CTP class B/C (HR, 0.46; p < 0.01) but not in those with no/mild ascites, HVPG < 16 mmHg, or CTP class A. Low-dose NSBB group showed a significant reduction in mortality compared with non-NSBB (moderate/severe ascites: HR, 0.61; p = 0.02 and CTP class B/C: HR, 0.41; p < 0.01) and the effect size was stronger than the high-dose NSBB. NSBB was associated with a reduced risk of infection (HR, 0.36; p = 0.01). In the SP group, NSBB prolonged survival in patients with moderate/severe ascites (HR, 0.56; p = 0.02), HVPG ≥ 16 mmHg (HR, 0.42; p < 0.01), or CTP class B/C (HR, 0.52; p < 0.01). Low-dose NSBB was more beneficial with 56% risk reduction (p < 0.01) of mortality compared with 33% risk reduction in the high-dose NSBB (p = 0.05). CONCLUSION: NSBB therapy was associated with longer survival in PP and SP groups who had an advanced stage of cirrhosis. Moreover, low-dose NSBB exhibited a better benefit than a standard-titrated high-dose NSBB with better tolerability.

Endothelial Cells Differentiated from Porcine Epiblast Stem Cells.

Pluripotent stem cells (PSCs) have the ability of self-renewal that can retain the characteristics of the mother cell, and of pluripotency that can differentiate into several body types. PSCs typically include embryonic stem cells (ESCs) derived from the inner cell mass of the preimplantation embryo, and epiblast stem cells (EpiSCs) derived from the epiblast of postimplantation embryo. Although PSCs are able to be used by differentiation into endothelial cells as a potential treatment for vascular diseases, human ESCs and induced PSCs (iPSCs) are followed by ethical and safety issues. Pigs are anatomically and physiologically similar to humans. Therefore, the goal of this study was to establish an efficient protocol that differentiates porcine EpiSCs (pEpiSCs) into the endothelial cells for applying the treatment of human vascular diseases. As a result, alkaline phosphatase (AP)-negative (-) pEpiSCs cultured in endothelial cell growth basal medium-2 (EBM-2) differentiation medium in association with 50 ng/mL of vascular endothelial growth factor (VEGF) for 8 days were changed morphologically like the feature of endothelial cells, and expression of pluripotency-associated markers (OCT-3/4, NANOG, SOX2, and C-MYC) in porcine differentiated cells was significantly decreased (p < 0.05). Additionally, when pEpiSCs were cultured in EBM-2 + 50 ng/mL of VEGF, porcine differentiated cells represented a common endothelial cell marker positive (CD31+) but monocytes and lymphocytes marker negative (CD45-). Therefore, these results indicated that pEpiSCs cultured in EBM-2 + 50 ng/mL of VEGF culture condition were efficiently differentiated into endothelial cells for the treatment of blood vessel diseases.

Decreased cardiovascular death in schizophrenia patients treated with antipsychotics: A Korean national cohort study.

BACKGROUND: Patients with schizophrenia have a reduced life expectancy, but the association between antipsychotic usage and cause of death is uncertain. METHODS: The authors observed associations of antipsychotic usage with the mortality rate and cause of death in a population-based cohort of the Korean National Health Insurance Service database from 2003 to 2017. A total of 86,923 patients with schizophrenia were categorized by the total duration of antipsychotic prescription after schizophrenia diagnosis into treated (n = 77,139) and untreated (n = 9784) groups. The main outcome was all-cause mortality; causes of death included cardiovascular disease, pulmonary disease, diabetes, cancer, accident, suicide and homicide. RESULTS: The numbers of all-cause deaths and deaths from individual causes were significantly lower in the antipsychotic-treated group than in the untreated group (all cases, p < 10-4). When adjusted for covariates (age, sex, income, body mass index, alcohol consumption, hypertension, cancer and cerebral stroke), mortality rates due to ischemic heart disease (hazard ratio, HR, 0.38 [95% CI, 0.18-0.77]) and stroke (HR, 0.39 [95% CI, 0.19-0.80]) were significantly lower in the antipsychotic-treated group. Among 4 atypical antipsychotics (olanzapine, risperidone, aripiprazole and quetiapine), only aripiprazole was associated with a decreased mortality risk relative to olanzapine (HR, 0.55 [95% CI, 0.32-0.96]). CONCLUSIONS: Schizophrenia patients constantly prescribed antipsychotics had significantly lower rates of death from certain cardiovascular illnesses than untreated patients. Aripiprazole-treated schizophrenia was associated with a decreased risk of death compared with olanzapine-treated disease.

Individualized surveillance of chronic hepatitis B patients according to hepatocellular carcinoma risk based on PAGE-B scores.

BACKGROUND AND AIMS: Current guidelines for chronic hepatitis B (CHB) patients are to undergo surveillance for hepatocellular carcinoma (HCC) with 6-month ultrasonography. We aimed to compare detection rates of very-early-stage HCC in two groups: group A, undergoing 6-month ultrasonography versus group B, undergoing 6-month ultrasonography alternating with dynamic computed tomography (CT). METHODS: This retrospective study assessed 2151 CHB patients under entecavir/tenofovir therapy from 2007 to 2016. Detection rates of very-early-stage HCC were compared between groups A/B at intermediate/high risk based on platelets, age, gender-hepatitis B scores. The primary endpoint was the proportion of patients in each group with very-early-stage HCC. Cox proportional hazards model was used to assess the effect of surveillance modalities to detect very-early-stage HCC. RESULTS: Five-year cumulative HCC incidence rates in group A were 15.0% not significantly different from 18.2% in group B at high risk (P = 0.17). Detection rates of very-early-stage HCC were significantly higher in group B than in group A (P < 0.001), and surveillance using CT alternating with ultrasonography was significantly associated with detection of very-early-stage HCC (hazard ratio 3.89, P < 0.001). Among intermediate-risk patients, difference between detection rates of very-early-stage HCC in groups A and B was not significant (P = 0.30), and surveillance using CT alternating with ultrasonography was not significantly associated with detection of very-early-stage HCC (hazard ratio 1.61, P = 0.23). CONCLUSION: In high-risk CHB patients, surveillance using CT alternating with ultrasonography led to higher detection rates of very-early-stage HCC compared to surveillance using ultrasonography.

Serum Myostatin Predicts the Risk of Hepatocellular Carcinoma in Patients with Alcoholic Cirrhosis: A Multicenter Study.

Background and Aim: Previous studies reported that serum myostatin is associated with sarcopenia. We aimed to elucidate the association between serum myostatin levels and hepatocellular carcinoma (HCC) development in patients with alcoholic liver cirrhosis (ALC). Methods: This retrospective, multicenter study assessed 1077 Asian ALC patients enrolled from 2007 to 2017. The primary endpoint was the development of HCC within 5 years. Cox proportional hazards model analyses were used to assess the association of serum myostatin levels and HCC development. The time-dependent areas under the receiver operating characteristic curve (AUROC) of serum myostatin for 5-year HCC development were calculated. Serum myostatin levels were measured using an enzyme-linked immunosorbent assay with samples collected on the index date. Results: During a median follow-up of 2.5 years, 5-year cumulative HCC incidence rates were 6.7% in the total population. The median level of serum myostatin was 3.3 ng/mL (interquartile, 2.1-5.2 ng/mL). The AUROC of serum myostatin for 5-year HCC development was 0.78 (95% confidence interval [CI], 0.76-0.81). In Cox proportional hazards model analyses, age, gender, platelet counts, and serum myostatin levels were independent risk factors for HCC development (adjusted hazard ratios [HRs] of age, male gender, platelet counts, and serum myostatin: 1.03, 2.79, 0.996, 1.18, respectively; all p < 0.05). Patients with high myostatin levels had a significantly higher risk of 5-year HCC development than those with low myostatin levels (HR 7.53, p < 0.001). Conclusion: Higher serum myostatin levels were significantly associated with a higher risk of developing HCC in ALC patients, which could identify high-risk patients who need stringent surveillance.

Serrated Polyposis Syndrome with a Synchronous Colon Adenocarcinoma Treated by an Endoscopic Mucosal Resection.

Serrated polyposis syndrome (SPS) can transform to malignant lesions through the sessile serrated pathway and traditional serrated pathway. These pathways may cause rapid neoplastic progression compared to the adenoma-carcinoma sequence, which may cause interval colorectal cancer. The authors experienced a case of SPS with a synchronous colon adenocarcinoma that was treated with an endoscopic mucosal resection. In pathology reviews, other parts of the adenocarcinoma showed sessile serrated adenoma. Therefore, patients with SPS have a potential for malignant transformation, highlighting the need for strict colonoscopy surveillance starting at the time of SPS diagnosis.

Attenuated Visual Function in Patients with Major Depressive Disorder.

BACKGROUND: We sought to investigate visual function, primarily, and structural changes in retinal ganglion cells, secondarily, in patients with major depressive disorder. METHODS: A total of 50 normal participants and 49 patients with major depressive disorder were included in this cross-sectional study. The participants underwent 24-2 standard automated perimetry and spectral-domain optical coherence tomography. RESULTS: The pattern standard deviation (PSD) in the visual field test was higher in the major depressive disorder patients than in the normal control subjects (P = 0.017). The patients with major depressive disorder showed reduced minimum ganglion cell-inner plexiform layer (GCIPL) thickness relative to the normal control participants (P = 0.015). The average score on the Hamilton Depression Rating scale showed a significant correlation with the PSD, minimum GCIPL thickness, and inferior GCIPL thickness (r = 0.265, P = 0.009; r = -0.239, P = 0.017; and r = -0.204, P = 0.043, respectively). The multivariate analysis of factors associated with PSD showed old age and a high Hamilton Depression Rating score to be relevant (P = 0.002 and 0.028, respectively). CONCLUSIONS: Visual function was decreased and the GCIPL thickness was reduced in major depressive disorder patients. The retinal neurodegenerative process in depression might be considered in patients with depression.

Liver Dysfunction in Sepsis.

Sepsis is defined as a life-threatening organ dysfunction caused by a dysregulated host response to infection. During sepsis, the liver has essential roles, such as immune defense and metabolic adaptation to inflammation. In addition, it is a target for sepsis-related injury, including hypoxic hepatitis, cholestasis, drug-induced liver injury, and secondary sclerosing cholangitis in critically ill patients. In particular, the mortality rate due to sepsis is four times higher in patients with cirrhosis, warranting a high index of suspicion for infection, appropriate diagnosis, and prompt antimicrobial treatment. The most recent definition of sepsis (Sepsis-3) no longer uses systemic inflammatory response syndrome (SIRS) and is based on the signs of organ dysfunction, which can be assessed by the Sequential Organ Failure Assessment (SOFA) and quick SOFA (qSOFA) scores. The qSOFA score can be applied at the bedside before any tests and is believed to be suggestive of sepsis when at least two of the following criteria are met: altered consciousness, respiratory rate ≥22/min, and systolic blood pressure ≤100 mmHg.
