Abstract
An intrahepatic portosystemic venous shunt (IPSVS) is a rare vascular abnormality, particularly in patients without cirrhosis. An 80-year-old woman without a history of chronic liver disease was admitted to our hospital with hepatic encephalopathy. Computed tomography revealed multiple IPSVSs with two large shunts in segment 6. As conservative therapies were insufficient for treating the symptoms and reducing ammonia levels, retrograde transcaval obliteration was performed. The two large shunts were successfully embolized using detachable coils. Consequently, hyperammonemia and hepatic encephalopathy dramatically improved, and the triphasic wave patterns of the electroencephalogram disappeared. Retrograde transcaval obliteration may be effective for refractory hepatic encephalopathy with IPSVS.

Abstract
A 42-year-old man was referred to our hospital because of anemia. The patient underwent gastroscopy and colonoscopy, but no bleeding site was detected. Abdominal contrast-enhanced computed tomography (CT) showed vascular dilatation along the wall of the small intestine. Small bowel capsule endoscopy and antegrade double-balloon endoscopy (DBE) were performed, and the patient was diagnosed with a small intestinal arteriovenous malformation (AVM). The AVM was clipped using DBE. After clipping, abdominal contrast-enhanced CT and small bowel angiography revealed the disappearance of the AVM. DBE may be a viable therapeutic option, helping avoid surgery and its associated risks.

Abstract
Atezolizumab and bevacizumab are currently available as first-line treatments for unresectable hepatocellular carcinoma, but immune-related adverse events are a major concern. We herein report two cases of isolated adrenocorticotropic hormone (ACTH) deficiency. Both patients presented with general fatigue, appetite loss, eosinophilia, and hyponatremia after nine cycles in case 1 and three months after stopping treatment for inflammatory arthritis in case 2. Endocrinological investigations revealed unsatisfactory ACTH and cortisol responses despite the preservation of other anterior pituitary hormones, suggesting isolated ACTH deficiency. As it is rapidly improved by steroid replacement therapy, an early diagnosis and treatment make it possible to resume immunotherapy.

Abstract
BACKGROUND Non-alcoholic fatty liver disease (NAFLD) is usually asymptomatic and lacks a specific biomarker; therefore, many individuals might remain undiagnosed even with advanced liver fibrosis. The aim of this study was to clarify the prevalence and clinical features of subjects with a high risk of advanced liver fibrosis in the general population, using the Fibrosis-4 (FIB-4) index. METHODS We retrospectively investigated 6,087 subjects without known liver disease who had participated in an annual health checkup examination. We analyzed the factors associated with high FIB-4 index (≥ 2.67) using a logistic regression analysis. RESULTS Among the 6,087 subjects, 76 (1.2%) had high FIB-4 index. Multivariate analysis identified hypertension (odds ratio [OR]; 9.040; 95% confidence interval [CI], 4.081-20.024; P < 0.001) and diabetes mellitus (OR = 4.251; 95% CI, 1.773-10.193; P = 0.001) as important risk factors for high FIB-4 index. The rates of hypertension and diabetes mellitus in subjects with high FIB-4 index were 78.9% and 23.7%, respectively. No significant association was observed between obesity or large waist circumference and high FIB-4 index. A history of cardiovascular disease was significantly more common in subjects with high FIB-4 index. These results were also observed in subjects with normal liver function test. CONCLUSIONS The present study revealed that approximately 1% of the general Japanese population has a high risk of advanced liver fibrosis. Many of these patients had hypertension and/or diabetes mellitus. Our findings suggest that there are many undiagnosed patients NAFLD with risk of advanced liver fibrosis in the general population.

Abstract
Background Serum hepatitis B surface antigen (HBsAg) is a component of both hepatitis B virus (HBV) virions and non-infectious subviral particles (SVPs). Recently, O-glycosylation of the PreS2 domain of middle HBsAg protein has been identified as a distinct characteristic of genotype C HBV virions versus SVPs. This study aimed to evaluate serum O-glycosylated HBsAg levels in patients with chronic hepatitis B (CHB) treated with nucleos(t)ide analogs (NAs). Methods Forty-seven treatment-naïve patients with genotype C CHB were retrospectively enrolled. Serum O-glycosylated HBsAg levels at baseline and after 48 weeks of NA therapy were quantified by immunoassay using a monoclonal antibody against the O-glycosylated PreS2 domain of middle HBsAg, and their correlations with conventional HBV marker levels were analyzed. Results At baseline, the serum O-glycosylated HBsAg levels were significantly correlated with the HBV DNA (P = 0.004), HBsAg (P = 0.005), and hepatitis B-core related antigen (HBcrAg, P = 0.001) levels. Both HBV DNA and O-glycosylated HBsAg levels were decreased after 48 weeks of NA therapy. The significant correlation of the O-glycosylated HBsAg level with the HBsAg or HBcrAg level was lost in patients who achieved undetectable HBV DNA (HBsAg, P = 0.429; HBcrAg, P = 0.065). Immunoprecipitation assays demonstrated that HBV DNA and RNA were detected in the O-glycosylated HBsAg-binding serum fraction, and the proportion of HBV RNA increased during NA therapy (P = 0.048). Conclusion Serum O-glycosylated HBsAg levels change during NA therapy and may reflect combined levels of serum HBV DNA and RNA virions. An O-glycosylated HBsAg-based immunoassay may provide a novel means to monitor viral kinetics during NA therapy.

Abstract
Direct-acting antiviral (DAA) therapy carries a potential risk of inducing hepatitis B virus (HBV) reactivation. However, the HBV kinetics during and after DAA therapy in patients co-infected with hepatitis C virus (HCV) and HBV remain unknown. We retrospectively evaluated the HBV kinetics during and after sofosbuvir/ribavirin therapy in four HBV inactive carriers co-infected with HCV. HCV was eradicated in all patients. Changes in HBV-DNA levels during treatment differed among patients. The hepatitis B surface antigen (HBsAg) levels uniformly decreased (mean -0.530 logIU/mL) by the end of treatment and returned to near the baseline in all patients. Sofosbuvir/ribavirin therapy thus demonstrated a suppressive effect on HBsAg.

Post‐treatment serum Wisteria floribunda agglutinin‐positive mac‐2‐binding protein level is a useful predictor of hepatocellular carcinoma development after hepatitis C virus eradication. JGH Open 2021; 5:1203-1209.

Abstract
Aims Recent advances of direct‐acting antiviral drugs for hepatitis C virus (HCV) have dramatically improved the sustained virologic response (SVR) rate, but hepatocellular carcinoma (HCC) development rarely occurs even in patients who achieve an SVR. Wisteria floribunda agglutinin‐positive mac‐2‐binding protein (WFA+‐M2BP) was recently developed as a noninvasive biomarker of liver fibrosis. However, the association between the WFA+‐M2BP level and HCC development after the achievement of an SVR is unclear. Methods and Results We examined the association between WFA+‐M2BP and HCC development in 522 HCV patients who achieved an SVR (Interferon [IFN]‐based therapy, n = 228; IFN‐free therapy, n = 294). Multivariate analysis revealed that a high WFA+‐M2BP level at SVR week 24 after treatment (SVR24) (hazard ratio [HR] = 1.215, P = 0.020), low platelet counts (HR = 0.876, P = 0.037), and old age (HR = 1.073, P = 0.012) were independent risk factors for HCC development regardless of the treatment regimen. Receiver operator characteristics curve analysis revealed that a WFA+‐M2BP level at SVR24 of ≥1.62 cut‐off index (COI) was the cut‐off value for the prediction of HCC development (adjusted HR = 12.565, 95% CI 3.501–45.092, P < 0.001). The 3‐ and 5‐year cumulative incidences of HCC were 1% and 1.6% in patients with low WFA+‐M2BP at SVR24 (<1.62 COI), and 4.7% and 12.5% in patients with high WFA+‐M2BP (≥1.62 COI) were, respectively (P < 0.001). Conclusions The assessment of liver fibrosis using the WFA+‐M2BP level at SVR24 is a useful predictor of HCC development after HCV eradication even in the IFN‐free therapy era.

Abstract
METHODS Two hundred and forty seven of 480 patients with naïve papilla undergoing therapeutic ERCP between April 2013 and March 2018 were enrolled for the study. The following patient characteristics were investigated: age, sex, body mass index, previous diseases (heart disease, renal failure, cerebrovascular disorders, coexisting malignancy and pulmonary disease), history of PEP, common bile duct diameter, diverticula and volume of fluid infused 24 hours after the procedure. All ERCP cases had naïve papilla and had undergone treatment. RESULTS The incidence of PEP was 8.5%. Significant differences were observed in the volume of fluid infused between patients without and with a history of heart disease (1,380 vs. 1,755 mL). The mean volume of the infused fluid was significantly lower in the PEP than non-PEP group (1,483 vs. 1,688 mL, P = 0.02). Moreover, PEP incidence differed according to a fluid infusion cutoff of 1,000 mL (7 vs. 11 cases of PEP in those with ≦1,000 mL and >1,000 mL fluid volume, respectively, P < 0.001). CONCLUSION Restricted fluid volume was a newly identified risk factor for PEP, particularly in patients with heart and renal diseases as comorbidities.

Abstract
AIM Chronic liver insufficiency is often associated with changes in amino acid metabolism. We evaluated whether change in serum amino acid concentrations had prognostic value among patients with liver cirrhosis. METHODS This retrospective study evaluated 158 patients who had been hospitalized with cirrhosis. Baseline serum concentrations of branched-chain amino acids (BCAAs) and tyrosine, as well as the BCAA-to-tyrosine ratio, were evaluated. Cox proportional hazards analysis was used to calculate the hazard ratios for factors that were associated with mortality or liver transplantation. RESULTS Among the 158 patients, baseline measurements showed decreased serum BCAA concentrations for 59 patients (37.3%), elevated serum tyrosine concentrations for 80 patients (50.6%), and a decreased BCAA-to-tyrosine ratio for 114 patients (72.2%). During a median follow-up period of 3.0 years, death or liver transplantation occurred at a rate of 0.136 cases/1 person-year. Multivariable analysis showed that transplant-free survival was independently predicted by older age, male sex, comorbid hepatocellular carcinoma, Child-Turcotte-Pugh score, and serum tyrosine concentration. Receiver operating characteristic curve analysis showed that a serum tyrosine concentration of >110 µmol/L was the optimal cut-off value for predicting transplant-free survival (adjusted hazard ratio 1.89, 95% confidence interval 1.15-3.11, p = 0.012). Kaplan-Meier analysis showed a significant difference in the 5-year transplant-free survival probability between patients with high and low serum tyrosine concentrations (42.1% vs. 60.7%, p < 0.001). CONCLUSIONS Elevated serum tyrosine concentration, but not changes in serum BCAA concentration or the BCAA-to-tyrosine ratio, may indicate a high risk of death or liver transplantation for patients with liver cirrhosis.

Abstract
Management of hemosuccus pancreaticus (HP) due to pancreatic adenocarcinoma is problematic. This is the first report of the successful management of HP caused by pancreatic adenocarcinoma by chemoradiotherapy, which is a treatment option for cases with a high surgical risk that are not suitable for interventional radiology. In the present case, bloody pancreatic juice was detected in the main pancreatic duct, and anemia worsened without repeated blood transfusions. The patient ultimately underwent chemoradiotherapy comprising radiation of 3 Gy in 15 fractions concomitant with systemic chemotherapy of S-1. After the treatments, the anemia improved, and the patient was discharged on day 45.

Abstract
AIM Chronic liver insufficiency is often associated with alteration in amino acid metabolism. We evaluated the prognostic value of changes in serum amino acid concentrations in patients with primary biliary cholangitis. METHODS A total of 75 primary biliary cholangitis patients who started urusodeoxycholic acid therapy were retrospectively enrolled. Baseline serum concentrations of branched-chain amino acids and tyrosine, and branched-chain amino acid-to-tyrosine ratio were determined. The hazard ratios of factors associated with liver-related events were analyzed by Cox proportional hazard analysis. RESULTS Of the 75 patients enrolled, 12 showed a decrease in serum branched-chain amino acid levels, and 15 showed an increase in serum tyrosine levels. The branched-chain amino acid-to-tyrosine ratio decreased in 16 patients. During a median 5.6-year follow up, liver-related events occurred in 11 patients. Multivariate analysis showed that high serum tyrosine levels at baseline and high alkaline phosphatase levels 48 weeks after starting urusodeoxycholic acid therapy were independent risk factors for event occurrence. From the receiver operator characteristics curve analysis, serum tyrosine concentration >110 μmol/L was identified as a cut-off value with an adjusted hazard ratio of 20.9 (95% confidence interval 4.3-101.5, P < 0.001). Kaplan-Meier analysis showed that the 5-year cumulative incidences of event occurrence in patients with high and low serum tyrosine concentration were 56.5% and 5.5%, respectively (P < 0.001). The 10-year survival probabilities also showed significant differences between patients with high and low serum tyrosine concentration (44.9% vs. 92.0%, P < 0.001). CONCLUSION Elevation of serum tyrosine concentration indicates a high risk of liver-related events in primary biliary cholangitis patients receiving urusodeoxycholic acid therapy.

Abstract
Follow-up computed tomography revealed a 40-mm pancreatic tail cyst in a 59-year-old man with type 1 diabetes mellitus. An intraductal papillary mucinous neoplasm was suspected; mucinous cystic neoplasm (MCN) was not considered because the patient was a man. During follow-up, cyst infection occurred but was improved by conservative treatment. At the 24-month follow up examination, cyst nodules had developed, corresponding to an increase in the carbohydrate antigen 19-9 level. Mucinous cystadenocarcinoma (MCC) was diagnosed pathologically based on distal pancreatectomy. A diagnosis of male MCN/MCC is often delayed, which may lead to a poor prognosis. MCN infection is also rare and poorly recognized. We observed an atypical male case of MCN/MCC.

Abstract
A 45-year-old man with steroid-dependent ulcerative pancolitis was hospitalized with frequent diarrhea, abdominal pain and distension 3 months after induction of golimumab, a tumor necrosis factor-alpha antagonist. Computed tomography showed wall thickening from the stomach to the colon and massive ascites. Peripheral blood test revealed eosinophilia. A large number of eosinophils were observed in the ascites fluid. Although esophagogastroduodenoscopy showed no abnormal findings and colonoscopy showed ulcerative colitis with a Mayo endoscopic subscore of 1, eosinophil infiltration was histologically observed. Based on these findings, we diagnosed him with eosinophilic gastroenteritis and started prednisolone. Consequently, his eosinophil counts and abdominal symptoms dramatically improved.

Abstract
Abstract
Background
Introduction: Several studies have reported that durable polymer drug-eluting stents could cause delayed healing and late catch-up. Although biodegradable polymer everolimus-eluting stents (BP-EES) might solve these problems, there is few data about mid-term clinical outcomes of BP-EES compared with durable polymer everolimus-eluting stents (DP-EES).
Purpose
This study aimed to compare mid-term clinical outcomes between BP-EES and DP-EES.
Methods
Between January to December 2016, 206 consecutive patients were treated with BP-EES and 177 consecutive patients were treated with DP-EES in our Heart Center. The primary endpoint was 3-year cumulative incidence of target lesion failure (TLF) defined as cardiac death, target vessel-related myocardial infarction and clinical-driven target lesion revascularization. Moreover, clinical-driven target vessel revascularization (TVR) and definite stent thrombosis (ST) were also evaluated.
Results
After propensity score matching, 160 patients were selected in each group. At 3 years, the cumulative incidences of TLF were 4.1% in BP-EES group vs. 7.9% in DP-EES (p = 0.12). Similarly, those of clinical-driven TVR were not different between the 2 groups (10.9% vs. 8.0%, p = 0.39). The incidence of definite ST in BP-EES tended to be higher than in that of DP-EES (BP-EES vs. DP-EES; 0% vs. 1.8%, p = 0.06).
Conclusions
There were no significant differences of TLF between BP-EES and DP-EES within 3 years. In this study, BP-EES seems to prevent definite ST and be safer than DP-EES in mid-term.

Abstract
Abstract
Objectives
We sought to evaluate the efficacy of plaque debulking by directional coronary atherectomy (DCA) before 2nd generation drug-eluting stent (DES) implantation for bifurcated coronary lesions.
Background
Percutaneous coronary intervention (PCI) for bifurcated lesions still remains complex and challenging in terms of restenosis or stent thrombosis regardless of whether simple or complex stenting used.
Methods
Patients with bifurcated lesions were enrolled in this prospective multicenter registry. Pre-2nd generation DES plaque debulking with a novel DCA was conducted. All patients were scheduled to perform a follow up (9–12 months) angiography (coronary angiography or coronary computed tomography). The primary end point was the target vessel failure (TVF) at follow-up. Secondary end points were procedure-related events and major adverse cardiac events at 1 year.
Results
A total of 77 patients with bifurcated lesions were enrolled. PCI with DCA was performed successfully in all without any major procedure-related event and only 1 case needed complex stenting. TVF rate at 9–12 months follow up was 3.9% (3 of 77) and those were all associated with revascularization of the target vessel. Restenosis was only observed at ostial of main-branch in 3cases. No death, no coronary artery bypass grafting, and no myocardial infarction were reported in the patients within the first year.
Figure1
Conclusion
DCA before 2nd generation DES implantation can possibly avoid complex stenting and provide a good mid-term outcome in patients with bifurcated lesions.

Abstract
Abstract
Background and introduction
Diabetic patients are at high risk of adverse cardiovascular events after percutaneous coronary intervention (PCI) even with durable polymer drug-eluting stents. A biodegradable polymer everolimus-eluting stents (BP-EES) might improve clinical outcomes in patients with diabetes mellitus.
Purpose
This study aimed to compare the mid-term clinical outcomes between BP-EES and durable polymer everolimus-eluting stents (DP-EES) in diabetic patients.
Methods
We investigated consecutive 383 patients treated with BP-EES or DP-EES at our Heart Center between January and December 2016. Among these patients, 155 (40.5%) patients had diabetes mellitus. The primary endpoint was 3-year cumulative incidence of target lesion failure (TLF) defined as target vessel-related myocardial infarction (MI) and clinical-driven target lesion revascularization (TLR). Moreover, the incidence of definite stent thrombosis (ST) was also evaluated.
Results
After propensity score matching, 148 patients were divided into 2 groups (BP-EES; N=74, DP-EES; N=74). The 3-year cumulative incidences of TLF were significantly lower in BP-EES group than in DP-EES group (BP-EES vs. DP-EES; 1.4% vs. 11.4%, p=0.01). The incidence of cardiac death, target vessel-related MI, and definite ST were none in the both group.
Figure 1
Conclusions
In diabetic patients, the incidence of TLR within 3 years was significantly lower in BP-EES than in DP-EES. In PCI for diabetic patients, BP-EES might improve clinical outcomes compared to DP-EES.

Abstract
A 42-year-old woman was admitted to our hospital with cholestatic liver injury. Serological examination revealed anti-mitochondrial M2 antibody positivity and anti-nuclear antibody and anti-smooth muscle antibody negativity. Histological examination of the first liver biopsy revealed chronic nonsuppurative destructive cholangitis with epithelioid granulomas. Ursodeoxycholic acid therapy successfully treated her cholestasis. Sixteen months later, she developed acute icteric hepatitis with elevation of serum aspartate and alanine aminotransferase levels. Anti-mitochondrial M2 positivity and anti-nuclear antibody and anti-smooth muscle antibody negativity persisted at that time. However, it became clear that anti-liver kidney microsomal type 1 antibody was positive. Histological examination of the second liver biopsy demonstrated scarce interface hepatitis and evident parenchymal inflammation and centrilobular zonal necrosis. Her liver biochemical test results promptly improved with the addition of prednisolone therapy. Considering the findings, she was diagnosed with primary biliary cholangitis-type 2 autoimmune hepatitis overlap syndrome. According to a literature review, this is an extremely rare autoimmune overlap syndrome.

Abstract
A 69-year-old man was under maintenance dialysis due to diabetic renal failure. He had a drop in blood pressure during dialysis, developed hematemesis, and was transported to our hospital. Emergency upper gastrointestinal endoscopy revealed diffuse erosion, mucosal sloughing, and edematous mucosa in the upper body of the stomach to the posterior wall of the antrum and to the greater curvature, which were considered to be an ischemic change. His underlying diseases included diabetic renal failure, chronic arteriosclerosis obliterans, cerebral infarction, internal carotid artery stenosis, hypertension, and myocardial infarction. Blood evaluation showed only mild inflammation and no fibrinolytic hyperactivity. Contrast-enhanced computed tomography (CECT) showed no occlusion of blood vessels. It was considered that the patient had a transient ischemic change due to blood pressure drop. The patient's condition improved with conservative treatment.

Aldo-keto reductase family 1 member B10 is associated with hepatitis B virus-related hepatocellular carcinoma risk. Hepatol Res 2017; 47:E85-E93. [PMID: 27084455 DOI: 10.1111/hepr.12725] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2016] [Revised: 04/12/2016] [Accepted: 04/13/2016] [Indexed: 12/25/2022]
Abstract
AIM Recent reports have indicated that aldo-keto reductase family 1 member B10 (AKR1B10), a cancer-related oxidoreductase, was upregulated in some chronic liver diseases. However, few studies have reported AKR1B10 expression in chronic hepatitis B virus (HBV)-infected patients. The aim of the present study was to analyze AKR1B10 expression and its relevance on hepatocellular carcinoma (HCC) development in patients with chronic HBV infection. METHODS Expression of AKR1B10 in the liver of 119 chronic HBV-infected patients was assessed and quantified immunohistochemically. A multivariate Cox model was used to estimate the hazard ratios of AKR1B10 expression for HCC development. The cumulative incidences of HCC were evaluated using Kaplan-Meier analysis. RESULTS Expression of AKR1B10 in the study cohort ranged from 0% to 84%. During the median follow-up time (6.2 years), 13 patients developed HCC. Multivariate analysis revealed that high AKR1B10 expression (≥15%) was an independent risk factor for HCC (hazard ratio, 10.8; 95% confidence interval, 3.0-38.6; P < 0.001). The 5-year cumulative incidences of HCC were 20.6% and 2.6% in patients with high and low AKR1B10 expression, respectively (P < 0.001). Patients with high AKR1B10 expression had significantly higher alanine aminotransferase levels during follow-up than those with low expression, even though antiviral treatment decreased HBV-DNA levels in both groups. CONCLUSION Chronic HBV-infected patients with high hepatic AKR1B10 expression had an increased risk of HCC development. This suggests that AKR1B10 upregulation might play a role in the early stages of HBV-related hepatocarcinogenesis.

Abstract
AIM To clarify the association between aldo-keto reductase family 1 member B10 (AKR1B10) expression and hepatocarcinogenesis after hepatitis C virus eradication.
METHODS In this study, we enrolled 303 chronic hepatitis C patients who had achieved sustained virological response (SVR) through interferon-based antiviral therapy. Pretreatment AKR1B10 expression in the liver was immunohistochemically assessed and quantified as a percentage of positive staining area by using image-analysis software. A multivariate Cox analysis was used to estimate the hazard ratios (HRs) of AKR1B10 expression for hepatocellular carcinoma (HCC) development after achieving SVR. The cumulative incidences of HCC development were evaluated using Kaplan-Meier analysis and the log-rank test.
RESULTS Of the 303 chronic hepatitis C patients, 153 (50.5%) showed scarce hepatic AKR1B10 expression, quantified as 0%, which was similar to the expression in control normal liver tissues. However, the remaining 150 patients (49.5%) exhibited various degrees of AKR1B10 expression in the liver, with a maximal AKR1B10 expression of 73%. During the median follow-up time of 3.6 years (range 1.0-10.0 years), 8/303 patients developed HCC. Multivariate analysis revealed that only high AKR1B10 expression (≥ 8%) was an independent risk factor for HCC development (HR = 15.4, 95%CI: 1.8-132.5, P = 0.012). The 5-year cumulative incidences of HCC development were 13.7% and 0.5% in patients with high and low AKR1B10 expression, respectively (P < 0.001). During the follow-up period after viral eradication, patients expressing high levels of AKR1B10 expressed markedly higher levels of alanine aminotransferase and α-fetoprotein than did patients exhibiting low AKR1B10 expression.
CONCLUSION Chronic hepatitis C patients expressing high levels of hepatic AKR1B10 had an increased risk of HCC development even after SVR.

Abstract
BACKGROUND AND AIM Aldo-keto reductase family 1 member B10 (AKR1B10), a cancer-related oxidoreductase, was recently reported to be upregulated in some chronic liver diseases. However, its relevance in hepatocellular carcinoma (HCC) development is not fully assessed, especially in patients with chronic hepatitis C virus (HCV) infection. METHODS Aldo-keto reductase family 1 member B10 expression in the liver of 550 patients with chronic HCV infection was immunohistochemically assessed and quantified. A multivariate Cox model was used to estimate the hazard ratios (HRs) of AKR1B10 expression for HCC development, and the cumulative incidence of HCC was evaluated using the Kaplan-Meier method. RESULTS Aldo-keto reductase family 1 member B10 expression in the patients ranged from 0% to 80%. During the median follow-up of 3.2 years, 43 of 550 patients developed HCC. Multivariate analysis demonstrated that high AKR1B10 expression (≥6%) was an independent risk factor for HCC (HR, 6.43; 95% confidence interval, 2.90-14.25; P < 0.001). The 5-year cumulative incidences of HCC were 22.8% and 2.2% in patients with high and low AKR1B10 expression, respectively (P < 0.001). In subgroup analyses, the effects of high AKR1B10 expression on HCC development risk were significant over strata. In particular, HRs attributed to high AKR1B10 expression were significant in the subgroups that had been considered at a lower risk of HCC, such as in patients with younger age and mild hepatic fibrosis or those who achieved sustained virological response after interferon therapy. CONCLUSION Various degrees of AKR1B10 upregulation in the liver were observed in patients with chronic HCV infection, and high AKR1B10 expression could be a novel predictor of HCC.

Abstract
BACKGROUND Insufficient information is available on the relationship between obesity and outcome of paediatric patients with acute pancreatitis. OBJECTIVES This study aimed to investigate the effect of obesity on outcomes of paediatric patients with acute pancreatitis based on a national administrative database. METHODS A total of 500 cases in 416 paediatric patients with acute pancreatitis (aged 5-17 years) were referred from 260 hospitals between 2010 and 2012 in Japan. Patients were divided into two groups according to the presence of obesity: with obesity (n = 65) and without obesity (n = 435). Patient data were collected from the administrative database to compare the prevalence of severe acute pancreatitis, in-hospital mortality, length of stay (LOS) and medical costs between the groups. RESULTS Both prevalence of severe acute pancreatitis and in-hospital mortality were significantly higher in paediatric patients with obesity than those without (36.9% vs. 16.3% and 3.1% vs. 0.0%; P < 0.001, respectively). Longer LOS and higher medical costs were also observed in paediatric patients with obesity (25.7 vs. 15.2 days, P < 0.001 and 14 169.5 vs. 7457.7 US dollars, P < 0.001, respectively). CONCLUSION This study demonstrated that obesity significantly influenced the outcomes of paediatric acute pancreatitis.

Abstract
This phase III study is the first study to demonstrate the superiority of new oral fluoropyrimidine S-1 over tegafur–uracil as adjuvant chemotherapy for stage II/III rectal cancer patients with no preoperative treatment in terms of relapse-free survival. S-1 can be considered an important option, especially for patients who have not received preoperative treatment. Backgrounds Preventing distant recurrence and achieving local control are important challenges in rectal cancer treatment, and use of adjuvant chemotherapy has been studied. However, no phase III study comparing adjuvant chemotherapy regimens for rectal cancer has demonstrated superiority of a specific regimen. We therefore conducted a phase III study to evaluate the superiority of S-1 to tegafur–uracil (UFT), a standard adjuvant chemotherapy regimen for curatively resected stage II/III rectal cancer in Japan, in the adjuvant setting for rectal cancer. Patients and methods The ACTS-RC trial was an open-label, randomized, phase III superiority trial conducted at 222 sites in Japan. Patients aged 20–80 with stage II/III rectal cancer undergoing curative surgery without preoperative therapy were randomly assigned to receive UFT (500–600 mg/day on days 1–5, followed by 2 days rest) or S-1 (80–120 mg/day on days 1–28, followed by 14 days rest) for 1 year. The primary end point was relapse-free survival (RFS), and the secondary end points were overall survival and adverse events. Results In total, 961 patients were enrolled from April 2006 to March 2009. The primary analysis was conducted in 480 assigned to receive UFT and 479 assigned to receive S-1. Five-year RFS was 61.7% [95% confidence interval (CI) 57.1% to 65.9%] for UFT and 66.4% (95% CI 61.9% to 70.5%) for S-1 [P = 0.0165, hazard ratio (HR): 0.77, 95% CI 0.63–0.96]. Five-year survival was 80.2% (95% CI 76.3% to 83.5%) for UFT and 82.0% (95% CI 78.3% to 85.2%) for S-1. The main grade 3 or higher adverse events were increased alanine aminotransferase and diarrhea (each 2.3%) in the UFT arm and anorexia, diarrhea (each 2.6%), and fatigue (2.1%) in the S-1 arm. Conclusion One-year S-1 treatment is superior to UFT with respect to RFS and has therefore become a standard adjuvant chemotherapy regimen for stage II/III rectal cancer following curative resection.

Abstract
OBJECTIVE To determine the mechanisms by which a traditional herbal medicine, Senkinnaidakusan (SKNS), controls Th2 responses, we examined the production of IL-12 by murine macrophages treated with SKNS. RESULTS Treatment with SKNS significantly increased TLR4 mRNA in macrophages. Furthermore, pre-treatment with SKNS enhanced the production of IL-12 by macrophages stimulated with LPS. When SKNS was orally administered to C3H/HeN mice at the induction phase after OVA sensitization, the serum levels of OVA-specific immunoglobulin (Ig)E and IgG1 decreased, Interleukin (IL)-4 production by spleen T cells in response to OVA was significantly suppressed, while interferon (IFN)-gamma production was increased. After nasal challenge of OVA, eosinophilic infiltration in the nasal mucosa and the number of sneezes were significantly inhibited in SKNS-treated mice compared with control mice. Besides, expression of IL-5 in the nasal mucosa was also inhibited. Using another strain of mice, C3H/HeJ (TLR4 negative), there was no difference in OVA-specific Igs or splenic cytokine production between the SKNS treatment and non-treatment groups. The eosinophilic infiltration in the nasal mucosa, the number of sneezes and IL-5 expression in the nasal mucosa were also not effected even after SKNS treatment. CONCLUSION These results suggest that oral administration of SKNS inhibits Th2 responses by enhancement of IL-12 release from macrophages via up-regulation of TLR4 expression.

Abstract
Bosonic superweakly interacting massive particles (super-WIMPs) are a candidate for warm dark matter. With the absorption of such a boson by a xenon atom, these dark matter candidates would deposit an energy equivalent to their rest mass in the detector. This is the first direct detection experiment exploring the vector super-WIMPs in the mass range between 40 and 120 keV. With the use of 165.9 day of data, no significant excess above background was observed in the fiducial mass of 41 kg. The present limit for the vector super-WIMPs excludes the possibility that such particles constitute all of dark matter. The absence of a signal also provides the most stringent direct constraint on the coupling constant of pseudoscalar super-WIMPs to electrons. The unprecedented sensitivity was achieved exploiting the low background at a level 10(-4) kg-1 keVee-1 day-1 in the detector.

Abstract
Background: LINE-1 methylation level is a surrogate marker of global DNA methylation. LINE-1 methylation in primary colorectal cancers (CRCs) is highly variable and strongly associated with a poor prognosis. However, no study has examined LINE-1 methylation levels of metastatic CRCs in relation to prognosis or assessed the heterogeneity of LINE-1 methylation level within the primary CRCs. Methods: Pyrosequencing was used to quantify LINE-1 methylation level in 42 liver metastases, 26 matched primary tumours, and 6 matched lymph node (LN) metastases. KRAS, BRAF, and PIK3CA mutation status and microsatellite instability (MSI) status were also examined. Results: The distribution of LINE-1 methylation level in liver metastases was as follows: mean, 67.3; range, 37.1–90.1. Primary tumours showed LINE-1 methylation levels similar to those of matched liver and LN metastases. The difference in LINE-1 methylation level between superficial areas and invasive front areas was within 7.0 in all six cases evaluated. Prognostic impact of LINE-1 hypomethylation in liver metastases on overall survival was not observed. The concordance rate was 94% for KRAS, 100% for BRAF, 88% for PIK3CA, and 97% for MSI. Conclusion: Alteration of LINE-1 methylation level may occur in early CRC tumorigenesis, and the LINE-1 methylation level is relatively stable during CRC progression.

Abstract
Increasing need for long-term care in older adults is expected with the ageing of Japan's population. The aim of the present study was to show the relationship between perceived chewing ability and long-term care needs for over 5 years in elderly persons. The chewing ability of 812 elderly persons living independently was evaluated at baseline using self-assessed masticatory ability, and it was classified into one of three categories: ability to chew all foods (good masticatory ability), ability to chew only slightly hard food (fair masticatory ability), and ability to only chew soft or pureed food (poor masticatory ability). Participants' care needs were then followed through Japan's long-term care insurance system for over 5 years. The log-rank test and Cox proportional hazard model were used to examine statistical differences in the frequency of care-needs certification between participants with good and fair or poor masticatory ability. Among participants aged 65-79 years, the frequency of care-needs certification was significantly higher in those with fair or poor masticatory ability than in those with good masticatory ability, and the relative hazard ratio was significantly higher in those with fair or poor masticatory ability than in those with good masticatory ability, after adjusting for age, gender, current employment status, educational background, social interaction, chronic medical conditions and dentition status. These relationships were not found among those aged 80-93 years. Impairment in perceived chewing ability may be associated with higher incidence of certification in Japan's long-term care insurance system among elderly persons aged 65-79.

Abstract
UNLABELLED Self-assessed masticatory ability has been shown to be significantly related to general health among elderly persons. OBJECTIVE To identify oral factors associated with the self-assessed masticatory ability. BASIC RESEARCH DESIGN Cross-sectional study. PARTICIPANTS A total of 736 community-dwelling elderly persons. MAIN OUTCOME MEASURES Data on background factors and the self-assessed masticatory ability were collected by questionnaire. An intraoral examination examined the pattern of posterior occluding pairs of natural teeth (POPs), the WHO Community Periodontal Index of Treatment Needs (CPI) and denture-related factors such as use of dentures, pain when using dentures and stability and retention of dentures. Chi-squared tests examined the relationships between the self-assessed masticatory ability and the background factors and oral conditions. Ordinal regression models were constructed with the self-assessed masticatory ability as the dependent variable and oral conditions as the principal independent variables, to adjust for the potential confounding variables. RESULTS Self-assessed impairment of masticatory ability was associated with lost POPs (p < 0.001) and CPI (p = 0.012). In the participants with lost POPs, self-assessed impairment of masticatory ability was associated with not using dentures and pain when using dentures (p < 0.001). In the totally edentulous subjects, impairment of masticatory ability was not associated with stability and retention of dentures (p = 0.070). CONCLUSIONS Factors affecting self-assessed masticatory ability include the pattern of POPs, periodontal status, denture use and pain when using dentures.

Abstract
Among the elderly, the quality of higher brain function is a contributing factor in performing activities of daily living. The aim of the study is to elucidate, epidemiologically, associations between mastication and higher brain function. A total of 208 community-dwelling elderly persons, aged 70-74 years, were enrolled. Self-assessed masticatory ability (masticatory ability) was classified into one of three categories: ability to chew all kinds of food, ability to chew only slightly hard food, or ability to chew only soft or pureed food. Brain function was assessed by four neuropsychological tests: Raven's Colored Progressive Matrices (RCPM) test, the Verbal Paired Associates 1 (VerPA) task and the Visual Paired Associates 1 task (from the Wechsler Memory Scale Revised Edition), and the Block Design subtest (from the Wechsler Adult Intelligence Scales-Third Edition). Correlations between masticatory ability and each test were examined using Spearman rank correlation coefficients. Multinominal logistic regression models were conducted with the neuropsychological tests as the dependent variables and masticatory ability as the principal independent variable to adjust for age, gender, educational background, social activity, drinking/smoking habits, chronic medical conditions and dental status. Significant correlations were found between the RCPM test, the VerPA task, the Block Design test and masticatory ability. In multinominal logistic regression models, poor masticatory ability was significantly and independently related to the categories under the mean-s.d. points compared with those of the mean ± s.d. ranges for RCPM test and the VerPA task. Significant associations may exist between mastication and higher brain function among the elderly.

Abstract
The escalating medical costs are a social problem in many countries. Masticatory ability is thought to be related to the general health conditions. The purpose of this study was to show relationships between self-assessed masticatory ability and medical costs among the elderly living independently in community. Data on background factors and self-assessed masticatory ability were collected from 702 Japanese elderly persons by questionnaires. An intra-oral examination was performed to examine the number of remaining teeth. Self-assessed masticatory ability was classified into one of three categories: ability to chew all kinds of food (Good), ability to chew only slightly hard food (Fair) or ability to chew only soft or pureed food (Poor). Data on the annual medical excluding dental costs were obtained from the Japanese National Health Insurance system. The Kruskal-Wallis test was used to examine differences in outpatient costs and hospitalisation costs among the three groups of self-assessed masticatory ability. Univariate unconditional logistic regression models and multivariate logistic regression models were used with medical costs as the dependent variable and self-assessed masticatory ability as the principal independent variable. A significant difference (P=0·039) in hospitalisation costs but not outpatient costs was found among the three groups of self-assessed masticatory ability. The multivariate logistic regression analysis showed that severely impaired masticatory ability (Poor) was significantly related to higher costs of hospitalisation. Self-assessed impairment of masticatory ability may be a significant and independent indicator of higher costs of hospitalisation among community-dwelling elderly persons.

Abstract
Myxomas are account for approximately half of primary cardiac tumors, and 75% cases originate in left atrium. We report our experience of a right atrial myxoma. A 68-year-old woman was referred to us due to anorexia, general fatigue and facial edema. Echocardiogram, computed tomography (CT), magnetic resonance imaging (MRI), and catheter angiocardiogram revealed a huge tumor in right atrium. The tumor was resected completely with the attached right atrial free wall under cardiopulmonary bypass. Pathological examination showed myxomatous tissue. Postoperative course was uneventful. She discharged the hospital on the 37th day after the operation, and is now doing well without any symptoms.

Abstract
Endoscopic submucosal dissection (ESD) with a knife is a technically demanding procedure that is associated with a high complication rate. The shortcoming of this method is the difficulty in fixing the knife to the target lesion. This difficulty can lead to unexpected incision, resulting in major complications such as perforation and bleeding. To reduce the risk of complications related to ESD, we developed a new grasping type scissors forceps (GSF), which can grasp and incise the targeted tissue using an electrosurgical current. The ESD procedure using the GSF was carried out in an animal model (resected porcine stomachs in vitro). After marking the lesion and injecting a solution into the submucosa, the lesion was separated from the surrounding normal mucosa following complete incision around the lesion using the GSF. A piece of submucosal tissue was grasped and cut with the GSF using an electrosurgical current to achieve submucosal exfoliation. ESD using the GSF was carried out safely and easily without unintentional incision. ESD using GSF appears to be an easy, safe, and technically efficient method for resecting gastrointestinal neoplasms.

Abstract
AIMS Although skin oxygenation is an important factor in the development and healing of foot ulcers, its regulation was not fully understood. We studied changes in foot skin oxygenation and blood flow during postural changes in patients with type 2 diabetes mellitus. METHODS Skin oxygenation was measured using transcutaneous oxygen pressure (TcPO(2)) and skin blood flow by laser Doppler flowmetry in 40 patients with type 2 diabetes mellitus without evidence of peripheral arterial disease and 13 healthy control subjects. RESULTS TcPO(2) in the supine position was significantly lower in patients with type 2 diabetes mellitus compared with control, although skin blood flow was not different. In the sitting position, TcPO(2) significantly increased in control and diabetic patients. The postural change-related increase in TcPO(2) was significantly enhanced in diabetic patients. On the other hand, skin blood blow significantly decreased in the sitting position from the supine position in control subjects but remained stable in diabetic patients. Orthostatic drop in systolic blood pressure correlated negatively with TcPO(2) in the supine position while correlated positively with %change in TcPO(2) and blood flow by postural changes. CONCLUSIONS The present study demonstrated the dissociated regulation of skin oxygenation and blood flow in response to leg dependency. Impaired postural vasoconstriction was associated with altered regulation of skin oxygenation probably due to sympathetic vascular dysfunction in diabetic patients.

Enhanced head-twitch response to 5-HT-related agonists in thiamine-deficient mice. J Neural Transm (Vienna) 2007; 114:1003-10.

Abstract
While many studies suggest an involvement of brain serotonergic systems in neuro-psychiatric disorders such as schizophrenia and depression, their role in Wernicke-Korsakoff syndrome (WKS) remains unclear. Since dietary thiamine deficiency (TD) in mice is considered as a putative model of WKS, it was used in the present study to investigate the function of serotonergic neurons in this disorder. After 20 days of TD feeding, the intensity of tryptophan hydroxylase immunofluorescence was found to be significantly decreased in the dorsal and medial raphe nuclei. In addition, the head-twitch response (HTR) elicited by the intracerebroventricular administration of the 5-HT(2A) agonist 2,5-dimethoxy-4-iodoamphetamine hydrochloride (DOI) was significantly increased in TD versus control mice, whereas the injection of ketanserin, a 5-HT(2A) receptor antagonist, prevented this enhancement. A single injection of thiamine HCl on the 19th day of TD feeding did not reduce the enhanced DOI-induced HTR. On the other hand, the administration of d-fenfluramine, a 5-HT releaser, did not enhance the HTR in TD mice. Together, our results indicate that TD causes a super-sensitivity of 5-HT(2A) receptors by reducing presynaptic 5-HT synthesis derived from degenerating neurons projecting from the raphe nucleus.
