Rationale, Design, and Baseline Characteristics of the Utopia Trial for Preventing Diabetic Atherosclerosis Using an SGLT2 Inhibitor: A Prospective, Randomized, Open-Label, Parallel-Group Comparative Study.

Introduction: Sodium-glucose co-transporter-2 (SGLT2) inhibitors are anti-diabetic agents that improve glycemic control with a low risk of hypoglycemia and ameliorate a variety of cardiovascular risk factors. The aim of the ongoing study described herein is to investigate the preventive effects of tofogliflozin, a potent and selective SGLT2 inhibitor, on the progression of atherosclerosis in subjects with type 2 diabetes (T2DM) using carotid intima-media thickness (IMT), an established marker of cardiovascular disease (CVD), as a marker.

Methods: The Study of Using Tofogliflozin for Possible better Intervention against Atherosclerosis for type 2 diabetes patients (UTOPIA) trial is a prospective, randomized, open-label, blinded-endpoint, multicenter, and parallel-group comparative study.

Antithrombin III for portal vein thrombosis in patients with liver disease: A randomized, double-blind, controlled trial.

Aim: Portal vein thrombosis (PVT) is one of the most critical disorders in liver disease patients. These patients have the imbalance of coagulation and coagulation inhibition resulting from decreased levels of coagulation inhibitory factors, such as protein C, protein S, and antithrombin III (AT-III). We designed this randomized, double-blind, placebo-controlled trial comparing the safety and efficacy of AT-III for PVT in liver disease patients with those who received no treatment.

Cost-effectiveness of EOB-MRI for Hepatocellular Carcinoma in Japan.

Purpose: The objective of the study was to evaluate the cost-effectiveness of gadoxetic acid-enhanced magnetic resonance imaging (EOB-MRI) in the diagnosis and treatment of hepatocellular carcinoma (HCC) in Japan compared with extracellular contrast media-enhanced MRI (ECCM-MRI) and contrast media-enhanced computed tomography (CE-CT) scanning.

Methods: A 6-stage Markov model was developed to estimate lifetime direct costs and clinical outcomes associated with EOB-MRI. Diagnostic sensitivity and specificity, along with clinical data on HCC survival, recurrence, treatment patterns, costs, and health state utility values, were derived from predominantly Japanese publications.

MicroRNA-196b is an independent prognostic biomarker in patients with pancreatic cancer.

Pancreatic cancer is a highly aggressive malignancy, with <50% patients surviving beyond 6 months after the diagnosis, and thus, there is an urgent need to explore new diagnostic and therapeutic approaches for this disease. Therefore, we conducted microRNA (miRNA) array analysis to detect miRNA molecules potentially associated with pancreatic cancer malignancy. To assess the identified miRNAs, we performed quantitative reverse transcription-PCR on 248 pancreatic ductal adenocarcinomas (UICC stage II).

EZH2 expression is a prognostic biomarker in patients with colorectal cancer treated with anti-EGFR therapeutics.

The polycomb group protein enhancer of zeste homolog 2 (EZH2) is a methyltransferase that suppresses microRNA-31 (miR-31) in various human malignancies including colorectal cancer. We recently suggested that miR-31 regulates the signaling pathway downstream of epidermal growth factor receptor (EGFR) in colorectal cancer. Therefore, we conducted this study for assessing the relationship between EZH2 expression and clinical outcomes in patients with colorectal cancer treated with anti-EGFR therapeutics.

Feasibility of Extracted-Overlay Fusion Imaging for Intraoperative Treatment Evaluation of Radiofrequency Ablation for Hepatocellular Carcinoma.

Background And Aims: Extracted-overlay fusion imaging is a novel computed tomography/magnetic resonance-ultrasonography (CT/MR-US) imaging technique in which a target tumor with a virtual ablative margin is extracted from CT/MR volume data and synchronously overlaid on US images. We investigated the applicability of the technique to intraoperative evaluation of radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC).

Methods: This retrospective study analyzed 85 HCCs treated with RFA using extracted-overlay fusion imaging for guidance and evaluation.

Ultra-deep sequencing analysis of resistance-associated variants during retreatment with simeprevir-based triple therapy after failure of telaprevir-based triple therapy in patients with genotype 1 hepatitis C virus infection.

Aim: Simeprevir (SMV)-based triple therapy is an effective retreatment option following failure of telaprevir (TVR)-based triple therapy. However, it is unclear whether the persistence of resistance-associated variants (RAVs) induced by TVR-based therapy may reduce the treatment effect of SMV-based therapy.

Methods: The factors associated with the treatment effect, including RAVs in the NS3 region, were examined in 21 patients with genotype 1b HCV infection who were treated with SMV-based therapy after failure of TVR-based therapy.

First-line cetuximab-based chemotherapies for patients with advanced or metastatic wild-type colorectal cancer.

Colorectal cancer (CRC) is one of the most commonly occurring cancers worldwide. A burgeoning number of studies have demonstrated that the addition of cetuximab to another standard first-line regimen markedly improves the outcome of CRC treatment. However, at present, the efficacy and safety of cetuximab-based combination chemotherapy has not been well described in Japan.

Effects of an Oral Elemental Nutritional Supplement on Post-gastrectomy Body Weight Loss in Gastric Cancer Patients: A Randomized Controlled Clinical Trial.

Background: Post-gastrectomy weight loss is associated with deterioration in quality of life, and influences the long-term prognosis of gastric cancer patients. We conducted a prospective, randomized controlled, open-label study to examine whether an oral elemental diet (Elental(®), Ajinomoto Pharmaceuticals, Tokyo, Japan; hereafter referred to as ED) prevents postoperative weight loss in post-gastrectomy patients.

Methods: Patients were randomly divided to receive the ED or control diet.

Impact of ribavirin dosage in chronic hepatitis C patients treated with simeprevir, pegylated interferon plus ribavirin combination therapy.

The factors associated with sustained virologic response (SVR) in chronic hepatitis C (CH-C) genotype 1 patients treated with simeprevir (SMV), pegylated interferon (Peg-IFN) plus ribavirin (RBV) triple therapy have not been fully investigated. Two hundred and twenty-nine treatment-naïve CH-C patients treated with SMV triple therapy were enrolled in this study. The overall SVR rate was 87% in per-protocol analysis.

Threshold doses and prediction of visually apparent liver dysfunction after stereotactic body radiation therapy in cirrhotic and normal livers using magnetic resonance imaging.

The purpose of the present study was to investigate the threshold dose for focal liver damage after stereotactic body radiation therapy (SBRT) in cirrhotic and normal livers using magnetic resonance imaging (MRI). A total of 64 patients who underwent SBRT for liver tumors, including 54 cirrhotic patients with hepatocellular carcinoma (HCC) and 10 non-cirrhotic patients with liver metastases, were analyzed. MRI was performed 3-6 months after SBRT, using gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced T1-weighted sequences.

Sitagliptin Attenuates the Progression of Carotid Intima-Media Thickening in Insulin-Treated Patients With Type 2 Diabetes: The Sitagliptin Preventive Study of Intima-Media Thickness Evaluation (SPIKE): A Randomized Controlled Trial.

Objective: The effect of additional treatment with oral hypoglycemic agents on the progression of atherosclerosis remains unknown in insulin-treated patients with type 2 diabetes mellitus (T2DM). We assessed the effects of sitagliptin, a dipeptidyl peptidase 4 inhibitor, on carotid intima-media thickness (IMT) in T2DM.

Research Design And Methods: This prospective, randomized, open-label, blinded end point, multicenter, parallel-group, comparative study included 282 insulin-treated patients with T2DM free of a history of apparent cardiovascular diseases who were recruited at 12 clinical units and randomly allocated to either the sitagliptin group (n = 142) or the control group (n = 140).

Methods: One hundred and thirty-seven chronic hepatitis B (CHB) patients receiving 90 μg or 180 μg of PEG IFN-α-2a for 24 or 48 weeks in phase II or III studies were enrolled in the study, including 100 HBeAg positive patients and 37 HBeAg negative patients; 121 patients (88.4%) had genotype C.

S100A8 Production in CXCR2-Expressing CD11b+Gr-1high Cells Aggravates Hepatitis in Mice Fed a High-Fat and High-Cholesterol Diet.

Nonalcoholic fatty liver disease (NAFLD) is a common chronic liver disease with a spectrum of presentations. S100A8 has been suggested to play a pivotal role as an endogenous immune-activator in inflammatory diseases. In this study, we investigated the involvement of S100A8 in the development of NAFLD.

Usefulness of ultrasonographic estimation of preperitoneal and subcutaneous fat thickness in the diagnosis of nonalcoholic fatty liver disease in diabetic patients.

Purpose: Nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) have been regarded as the hepatic manifestation of metabolic syndrome. Abdominal wall fat index (AFI), defined as the ratio of preperitoneal and subcutaneous fat thickness in the abdomen estimated by ultrasonography (US), has been shown to be useful in screening for disorders related to metabolic syndrome. We investigated the relation between AFI and NAFLD/NASH in diabetic patients.

[Two Cases of Intrapelvic Schwannoma].

A 67-year-old man (case 1) and 65-year-old man (case 2) were incidentally found to have a tumor in the retrovesical region. Computed tomography and magnetic resonance imaging demonstrated a solid tumor at the right side of the rectum. 2-Deoxy-2-[fluorine-18] fluoro-D-glucose (FDG) -positron emission tomography revealed uptake at the tumor.

Loss of interleukin-21 leads to atrophic germinal centers in multicentric Castleman's disease.

Both multicentric Castleman's disease (MCD) and immunoglobulin (Ig)G4-related disease (IgG4-RD) are systemic diseases, presenting with hypergammaglobulinemia and elevated serum levels of IgG4. However, with regard to histopathological findings, MCD shows atrophic germinal centers. On the other hand, expanded germinal centers are detected in IgG4-RD.

Kupffer phase image of Sonazoid-enhanced US is useful in predicting a hypervascularization of non-hypervascular hypointense hepatic lesions detected on Gd-EOB-DTPA-enhanced MRI: a multicenter retrospective study.

Background: It remains unknown whether Kupffer-phase images in Sonazoid-enhanced ultrasonography (US) can be used to predict hypervascularization of borderline lesions. Therefore, we aimed to clarify whether Kupffer-phase images in Sonazoid-enhanced ultrasonography can predict subsequent hypervascularization in hypovascular borderline lesions detected on hepatobiliary-phase gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging.

Methods: From January 2008 to March 2012, 616 low-intensity hypovascular nodules were detected in hepatobiliary-phase images of Gd-EOB-DTPA-enhanced MRI at nine institutions.

Clinical characteristics and prognosis of non-B non-C hepatocellular carcinoma patients with modest alcohol consumption.

Aim: Alcoholic hepatocellular carcinoma (ALD-HCC) accounts for the majority of non-B non-C HCC (NBNC-HCC) cases. Although alcohol is a potent carcinogen, there have been few reports on the influence of modest alcohol consumption in NBNC-HCC. This study aimed to investigate the clinical characteristics and prognosis of NBNC-HCC patients with modest alcohol consumption.

JSH Consensus-Based Clinical Practice Guidelines for the Management of Hepatocellular Carcinoma: 2014 Update by the Liver Cancer Study Group of Japan.

The Clinical Practice Guidelines for the Management of Hepatocellular Carcinoma proposed by the Japan Society of Hepatology was updated in June 2014 at a consensus meeting of the Liver Cancer Study Group of Japan. Three important items have been updated: the surveillance and diagnostic algorithm, the treatment algorithm, and the definition of transarterial chemoembolization (TACE) failure/refractoriness. The most important update to the diagnostic algorithm is the inclusion of gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging as a first line surveillance/diagnostic tool.
