A 2-Week Course of Enteral Treatment with a Very Low-Calorie Protein-Based Formula for the Management of Severe Obesity.

Background. Multiple weight loss failures among obese patients suggest the design of new therapeutic strategies. We investigated the role of 2-week course of enteral treatment with a very low-calorie protein-based formula in the management of severe obesity.

Histopathology of hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is currently the sixth most common type of cancer with a high mortality rate and an increasing incidence worldwide. Its etiology is usually linked to environmental, dietary or life-style factors. HCC most commonly arises in a cirrhotic liver but interestingly an increasing proportion of HCCs develop in the non-fibrotic or minimal fibrotic liver and a shift in the underlying etiology can be observed.

Frontotemporal dementia and its subtypes: a genome-wide association study.

Background: Frontotemporal dementia (FTD) is a complex disorder characterised by a broad range of clinical manifestations, differential pathological signatures, and genetic variability. Mutations in three genes-MAPT, GRN, and C9orf72--have been associated with FTD. We sought to identify novel genetic risk loci associated with the disorder.

CD4+/CD25+ T cells suppress autologous CD4+/CD25- lymphocytes and secrete granzyme B during acute and chronic hepatitis C.

We aimed to verify whether CD4(+)/CD25(+) T cells suppress CD4(+) T cells and secrete Granzyme B (GZB) during acute and chronic hepatitis C (CHC) infection. We enrolled 50 subjects: 20 patients with CHC (Group A), 15 healthy individuals (Group B), 10 patients with acute hepatitis C later evolved to persistent infection (Group C) and five patients who resolved hepatitis C virus infection during acute phase (Group D). We analysed, on enrolled subjects CD4(+)/CD25(+) T cells and related GZB production as well as Annexin V activity.

Enlargement of mitral valve ring in a young woman with severe prosthesis-patient mismatch.

Mechanical prosthesis is the first choice for valve replacement at the mitral position in children. Replacement of the original prosthesis because of prosthesis-patient mismatch (PPM) is almost inevitable when prostheses are implanted in small children. The impact of PPM on long-term mortality becomes significant when the effective orifice area (EOA) is severely reduced.

Sorafenib and entecavir: the dioscuri of treatment for advanced hepatocellular carcinoma?

Hepatitis B virus (HBV) is responsible for 50%-80% of cases of hepatocellular carcinoma (HCC) worldwide. Entecavir (ET) is a potent inhibitor of chronic HBV-DNA polymerase, inhibiting both the priming and elongation steps of viral DNA replication. Sorafenib (SO) has proven efficacy in prolonging survival in patients with advanced HCC.

Selection and management of hepatocellular carcinoma patients with sorafenib: recommendations and opinions from an Italian liver unit.

Sorafenib (SO) was the first systemic agent to demonstrate a significant improvement in overall survival in patients with advanced hepatocellular carcinoma (HCC); international guidelines now recommend SO as a first-line treatment in patients with unresectable HCC who are not eligible for locoregional therapies and maintain preserved liver function. However, therapy with SO may require close management to further optimize the clinical outcomes and limit the onset of adverse events (AEs). SO has been in use at our Liver Unit (Avellino, Italy) for over 4 years, and in that time 85 patients with HCC have been treated with SO.

Silybin combined with phosphatidylcholine and vitamin E in patients with nonalcoholic fatty liver disease: a randomized controlled trial.

The only currently recommended treatment for nonalcoholic fatty liver disease (NAFLD) is lifestyle modification. Preliminary studies of silybin showed beneficial effects on liver function. Realsil (RA) comprises the silybin phytosome complex (silybin plus phosphatidylcholine) coformulated with vitamin E.

Preservation of nutritional-status in patients with refractory ascites due to hepatic cirrhosis who are undergoing repeated paracentesis.

Background And Aim: Refractory ascites in liver-cirrhosis is associated with a poor prognosis. We performed a prospective study to investigate whether aggressive nutritional-support could improve outcomes in cirrhotic patients.

Methods: Cirrhotic patients undergoing serial large-volume paracentesis for refractory-ascites were enrolled and randomized into three groups.

Dysexecutive performance of healthy oldest old subjects on the Frontal Assessment Battery.

Background And Aims: Frontal lobes and executive functions appear to be more vulnerable to normal aging than other cerebral regions and domains. The aim of the study was to evaluate executive functions by the Frontal Assessment Battery (FAB) in healthy oldest old subjects free of dementia.

Methods: Thirty-two healthy oldest old subjects (age range 85-97 yrs) and 32 young old subjects (aged 61-74 yrs) were studied.

The HOX gene network in hepatocellular carcinoma.

Liver organogenesis and cancerogenesis share common mechanisms. HOX genes control normal development, primary cellular processes and are characterized by a unique genomic network organization. Less is known about the involvement of HOX genes with liver cancerogenesis.

Validation of an extension of the international non-invasive criteria for the diagnosis of hepatocellular carcinoma to the characterization of macroscopic portal vein thrombosis.

Background And Aim: We aimed to validate the non-invasive criteria for the characterization of portal vein thrombosis (PVT) in patients with cirrhosis and hepatocellular carcinoma (HCC). In a prospective study, we examined the impact of arterial hypervascularity, as established by the European Association for the Study of the Liver and the American Association for the Study of Liver Diseases recommendations for the non-invasive diagnosis of HCC, as a criterion for characterizing macroscopic PVT (EASL/AASLD extension criteria).

Methods: A total of 96 cases of PVT detected using ultrasonography in patients with cirrhosis and HCC were included in the study.

Oxidative stress and steatosis are cofactors of liver injury in primary biliary cirrhosis.

Background: Factors responsible for the progression of primary biliary cirrhosis (PBC) are still poorly understood. In the present study, we investigated the associations between the stage of PBC and the immune reaction triggered by oxidative stress; the presence of obesity, steatosis,steatohepatitis; and other toxic, metabolic, or steatogenic factors.

Methods: We studied clinical, laboratory, and histological data for 274 untreated patients with serum antimitochondrial antibody (AMA)-positive PBC.

Predicting fibrosis worsening in obese patients with NASH through parenchymal fibronectin, HOMA-IR, and hypertension.

Objectives: Few published studies have examined the results obtained from repeat liver biopsies in obese patients with nonalcoholic fatty liver disease (NAFLD). The progressive form of this disease may be largely limited to a subgroup of NAFLD patients with nonalcoholic steatohepatitis (NASH). The presence of intralobular fibronectin (Fn) and other variables was investigated in relation to subsequent fibrosis progression.

Contrast-enhanced sonography versus biopsy for the differential diagnosis of thrombosis in hepatocellular carcinoma patients.

Aim: To clarify which method has accuracy: 2nd generation contrast-enhanced ultrasound or biopsy of portal vein thrombus in the differential diagnosis of portal vein thrombosis.

Methods: One hundred and eighty-six patients with hepatocellular carcinoma and portal vein thrombosis underwent in blinded fashion a 2nd generation contrast-enhanced ultrasound and biopsy of portal vein thrombus; both results were examined on the basis of the follow-up of patients compared to reference-standard.

Results: One hundred and eight patients completed the study.

Relationships of PAI-1 levels to central obesity and liver steatosis in a sample of adult male population in southern Italy.

To analyse the relationship of PAI-1 plasma levels to echographically determined liver steatosis and cardiometabolic risk factors in a randomly selected sample of 254 adult male participants of the Olivetti Heart Study. Accounting for age and ongoing pharmacological treatment, PAI-1 levels were directly (P < 0.005) associated with body mass index (BMI), waist circumference (WC), serum triglyceride (TG), total cholesterol, insulin, homeostasis model assessment index, gamma-glutamyl transpeptidase and peritoneal fat.

Myocardial insulin-like growth factor-1 and insulin-like growth factor binding protein-3 gene expression in failing hearts harvested from patients undergoing cardiac transplantation.

Insulin-like growth factor-1 (IGF-1) and insulin-like growth factor binding proteins (IGFBPs) might play a pathogenic role in heart failure. We showed significantly increased myocardial IGFBP-3 expression (investigated by real-time polymerase chain reaction) and apoptosis (detected by flow cytometry) in 23 failing hearts from patients undergoing cardiac transplantation for end-stage dilated or ischemic cardiomyopathy, when compared with 10 controls. Higher IGF-1 mRNA levels were shown only in end-stage dilated cardiomyopathy.

Liver iron excess in patients with hepatocellular carcinoma developed on non-alcoholic steato-hepatitis.

Background/aims: Liver iron deposits are frequent in patients with non-alcoholic steato-hepatitis (NAFLD), but their role is not well defined. To investigate the effect of liver iron excess on the prevalence of hepatocellular carcinoma (HCC) in patients with NASH-related cirrhosis.

Methods: Hepatic iron was measured retrospectively with a semiquantitative method in liver biopsies of 153 patients with NASH-related cirrhosis: 51 with HCC and 102 controls without HCC, matched for age, sex and stage of liver disease.

Fronto-temporal dementia presenting as Geschwind's syndrome.

Geschwind described a syndrome (Geschwind syndrome, GS) in patients with temporal lobe epilepsy, characterized by sexual behavioural disorders, hyper-religiosity, hypergraphia and viscosity. In this report we describe a patient affected by fronto-temporal dementia (FTD), who showed all the personality changes of GS without having epilepsy, and suggest that clinicians should be aware of several other features in FTD, such as hyposexuality and hypergraphia, which are usually not noted during the diagnostic evaluation.

Incidence of hypertension in individuals with different blood pressure salt-sensitivity: results of a 15-year follow-up study.

Objective: To evaluate the incidence of hypertension and the rate of decline in renal function in a sample of 47 Olivetti Heart Study (OHS) participants whose blood pressure (BP) salt-sensitivity and renal tubular sodium handling had been assessed in 1987-88.

Methods: During the 2002-04 OHS follow-up examination, medical history, physical examination and blood and urine sampling were performed in 36 of the 47 participants to the baseline study (age 60 +/- 6 years; average follow-up = 15.1 +/- 0.

Mental status impairment in patients with West Haven grade zero hepatic encephalopathy: the role of HCV infection.

Background: In patients with cirrhosis, subclinical hepatic encephalopathy, which negatively affects the activity of daily living, is often unidentified. In a multicenter observational study, we investigated the possibility of detecting minimal neurological changes consistent with subclinical hepatic encephalopathy by using the Trail Making Test in a cohort of patients with liver cirrhosis at hospital admission.

Methods: Seventy-seven consecutive patients with liver cirrhosis were studied (mean age, 69.

Metabolic factors involved in the therapeutic response of patients with hepatitis C virus-related chronic hepatitis.

Background: The purpose of the present paper was to investigate the factors possibly involved in the failure of pegylated interferon (Peg IFN) plus ribavirin treatment at standard dosage in hepatitis C virus (HCV) 1b patients, with chronic hepatitis.

Methods: A fully screened population of 40 virological non-responders (NR) to combined antiviral therapy was selected and matched, 1:1, with a similar cohort of end-therapy virological responders (R).

Results: Waist circumference, glucose metabolic impairment, body mass index, non-genetic iron overload, steatosis and fibrosis severity and, finally, arterial hypertension were statistically more frequent in the NR group on Peg IFN plus ribavirin.

Flow cytometry assay of myeloid dendritic cells (mDCs) in peripheral blood during acute hepatitis C: possible pathogenetic mechanisms.

Aim: To asses the expression of myeloid dendritic cells (CD11c+) subset during acute HCV hepatitis and its possible involvement in natural history of the infection.

Methods: We enrolled 11 patients with acute hepatitis C (AHC) (Group A), 10 patients with acute hepatitis A (AHA) (as infective control-Group B) and 10 healthy donors (group C) in this study. All patients underwent selective flow cytometry gating strategies to assess the peripheral number of the myeloid dendritic cells (mDCs) to understand the possible role and differences during acute hepatitis.
