BACKGROUND: The use of left ventricular assist devices (LVADs) to treat advanced cardiac heart failure is constantly increasing, although this device leads to high risk for gastrointestinal bleeding. METHODS: Using in-silico flow analysis, we quantified hemodynamic alterations due to continuous-flow LVAD (HeartWare, Inc., Framingham, MA) in the celiac trunk and major branches of the abdominal aorta, and then explored the relationship between wall shear stress (WSS) and celiac trunk orientation...

To investigate the effects and mechanism of diosmetin on acute hepatic failure (AHF), an AHF murine model was established through administration of lipopolysaccharides/D-galactosamine (LPS/D-GalN). In vitro, diosmetin scavenged free radicals. In vivo, diosmetin decreased mortality among mice, blocked the development of histopathological changes and hepatic damage, and suppressed levels of inflammatory mediators and cytokines. In addition, diosmetin prevented the expression of phosphorylated IKK, IκBα, and NF-κB p65 in the NF-κB signaling pathway, and JNK and p38 in the MAPK signaling pathway...

PURPOSE: To evaluate the efficacy and toxicity of induction chemotherapy followed by concurrent chemoradiotherapy vs. concurrent chemoradiotherapy for locoregionally advanced nasopharyngeal carcinoma (NPC). METHODS: We reviewed data of locoregionally advanced NPC patients who underwent 2 different treatment plans, 1 with induction chemotherapy followed by concurrent chemoradiotherapy (IC + CCRT) and the other with only concurrent chemoradiotherapy (CCRT). All patients received cisplatin 80 mg/m(2) 3 weeks one cycle concurrently with intensity-modulated radiation therapy, and three IC protocols were included for the IC + CCRT group...

Purpose<br /> Bronchial and gastroenteropancreatic neuroendocrine tumors (NETs) are slow-growing tumors, which frequently express somatostatin receptors on their cell membranes. These receptors are targets for therapy with Lutetium-177-labeled somatostatin analogs. We have treated over 1200 patients with peptide receptor radionuclide therapy (PRRT) with (177)Lu-DOTA(0),Tyr(3)]octreotate ((177)Lu-DOTATATE) since the year 2000 and present the results on efficacy, survival and toxicity of this therapy. <p>Patients and methods<br /> For safety analysis, 610 patients treated with a cumulative dose of at least 100 mCi (3...

BACKGROUND AND AIMS: Controlled attenuation parameter (CAP) is a non-invasive method for measuring hepatic steatosis (HS). Non-alcoholic fatty liver disease (NAFLD) is closely related to cardiovascular diseases (CVDs). CVDs are the leading cause of morbidity and mortality in hemodialysis patients. The aim of this study was to investigate the prevalence of NAFLD in hemodialysis patients. METHOD: We prospectively enrolled patients undergoing chronic hemodialysis, as well as patients with normal renal function who served as controls...

AIM: Hepatitis B virus-related acute-on-chronic liver failure has high short-term mortality. Artificial liver support systems (ALSS) may improve outcome and avoid liver transplantation, but predicting short-term prognosis in such patients is difficult. This study aimed to determine whether the neutrophil-lymphocyte ratio (NLR), an inflammation marker, predicted mortality in patients treated with ALSS. METHODS: A total of 560 patients with hepatitis B virus-related acute-on-chronic liver failure were enrolled, 338 were treated with ALSS and the others treated with standard of care(SOC)...

In this study, canine adenoviruses (CAdVs) from two acute fatal cases of infectious canine hepatitis (ICH) were analyzed using molecular detection and sequencing of the pVIII, E3, and fiber protein genes. Pathological findings in affected dogs were typical for CAdV-1 associated disease, characterized by severe centrilobular to panlobular necrohemorrhagic hepatitis and the development of disseminated intravascular coagulation in the terminal stages of disease. Comparison of partial genome sequences revealed that although these newly detected viruses mainly had CAdV-1 genome characteristics, their pVIII gene was more similar to that of CAdV-2...

Progressive Familial Intrahepatic Cholestasis type 2 (PFIC2) is a rare cholestatic disorder diagnosed in infancy or childhood that can lead to severe hepatic fibrosis and liver failure. Mutations in the ABCB11 gene result in a deficiency of the bile salt export protein (BSEP) and accumulation of bile inside the hepatocytes. Hepatocellular carcinoma is another condition associated with severe forms of deletion mutations in the ABCB11 gene. Treatment options including ursodeoxycholic acid biliary diversion have mixed outcomes and some patients require liver transplantation...

INTRODUCTION: Recurrence of HCV infection in patients with chronic hepatitis C virus (HCV) at the time of liver transplantation is nearly universal and reduces the likelihood of graft and patient survival. MATERIALS AND METHODS: We evaluated outcomes of 17 patients (16 with HCV genotype 1 and 1 with genotype 4) who received up to 12 or 24 weeks of ledipasvir/sofosbuvir plus ribavirin prior to or up to the time of liver transplant in the SOLAR-1 and SOLAR-2 trials...

INTRODUCTION: Chronic hepatitis B (CHB) is associated with high burden and healthcare costs. Virologic response achieved with antivirals is associated with progression avoidance. This study aimed to estimate the efficiency and clinical impact of antiviral strategies in CHB patients. MATERIAL AND METHODS: A Markov model estimated lifetime complications and direct costs in both, HBeAg-positive and HBeAg-negative cohorts. Strategy 1 (71% of treated population) and strategy 2 (100%), both based on pegylated interferon (peg-IFN) followed by oral tenofovir or entecavir, were compared to no treatment...

BACKGROUND: The reconstruction of hepatic artery (HA) is most complex step in living donor liver transplantation (LDLT) due to smaller diameter of the artery and increased risk of HA related complications. Due to smaller diameter of the HA, many centres use microsurgical technique with interrupted sutures for arterial anastomosis. Aim of our study was to retrospectively investigate the outcomes after HA reconstruction performed under magnifying loupes using "parachute technique". MATERIALS AND METHODS: From August 2002 to 31(st) August 2016, LDLT was performed in 766 recipients...

AIM: There are no beneficial therapies except for emergency liver transplantation for acute liver failure (ALF). However, in Japan where a serious problem of a shortage of donor livers still remains, therapies other than transplantation must be further investigated for patients with ALF. Pro-inflammatory cytokines promoting tissue destruction are predominant at an early phase of ALF. Corticosteroid (CS) influences monocyte/macrophage differentiation, by suppressing pro-inflammatory genes, indicating CS treatment might be beneficial during the early phase of ALF...

Metabolic syndrome, an etiological factor in non-alcoholic fatty liver disease (NAFLD), is often present in hemodialysis patients. Little is known about the prevalence of, and factors associated with, liver fibrosis in hemodialysis populations. We used transient elastography (TE) to investigate these phenomena. 659 patients treated with chronic hemodialysis were enrolled. We excluded those with excess alcohol intake, liver stiffness measurement (LSM) failure, or unreliable LSM values. LSM ≥8.0 kPa was used as a cutoff suggesting clinically relevant fibrosis...

Approximately 350 million people worldwide are infected with hepatitis C virus (HCV), which is associated with morbidity and mortality related to cirrhosis, hepatocellular carcinoma, or liver failure. Recently, vast improvements have been made with the development of direct-acting antiviral (DAA) agents, which are all-oral, are better tolerated than interferon-based treatment, and provide a sustained virologic response in more than 90% of treated patients. This article reviews the new therapies available for HCV infection, with a focus on patients who have chronic HCV with and without compensated cirrhosis...

Cimaglermin alfa (GGF2) is a recombinant human protein growth factor in development for heart failure. Phase 1 trials were suspended when 2 cimaglermin alfa-treated subjects experienced concomitant elevations in serum aminotransferases and total bilirubin meeting current FDA criteria for a serious liver safety signal (i.e. "Hy's Law"). We assayed mechanistic biomarkers in archived clinical trial serum samples which confirmed the hepatic origin of the aminotransferase elevations in these two subjects and identified apoptosis as the major mode of hepatocyte death...

The term acute liver failure (ALF) is frequently applied as a generic expression to describe patients presenting with or developing an acute episode of liver dysfunction. In the context of hepatological practice, however, ALF refers to a highly specific and rare syndrome, characterised by an acute abnormality of liver blood tests in an individual without underlying chronic liver disease. The disease process is associated with development of a coagulopathy of liver aetiology, and clinically apparent altered level of consciousness due to hepatic encephalopathy...

Sacubitril/valsartan (LCZ696) is indicated for the treatment of heart failure with reduced ejection fraction. Absorption of sacubitril/valsartan and conversion of sacubitril (prodrug) to sacubitrilat (neprilysin inhibitor) was rapid with maximum plasma concentrations of sacubitril, sacubitrilat, and valsartan (angiotensin receptor blocker) reaching within 0.5, 1.5-2.0, and 2.0-3.0 h, respectively. With a two-fold increase in dose, an increase in the area under the plasma concentration-time curve was proportional for sacubitril, ~1...

BACKGROUND: Insufficient volume of the future liver remnant (FLR) is a major cause of non-resectable disease in patients presenting with primary or metastatic liver tumours. The objective of this study was to evaluate the safety and efficacy of the combined preoperative portal and hepatic vein embolization (biembolization) before extended right liver resections. METHODS: This retrospective study was performed in a tertiary centre between 2014 and 2015. Combined right portal and hepatic vein embolization (biembolization) was proposed, as an alternative to ALPPS procedure, for all patients with primary or metastatic liver tumour, before right extended hepatectomy...
