Hug sign in intraprocedural cone-beam-CT to predict short-term response to combined treatment of hepatocellular carcinoma.

Objectives: Combined treatment of ablation and chemoembolization for hepatocellular carcinoma represents a promising therapy to increase treatment efficacy and improve patient survival. The "hug sign" is a recently introduced radiological sign consisting in deposition of beads/contrast agent during transarterial chemoembolization in the hyperemic area surrounding the post-ablation volume, seen during intraprocedural unenhanced cone-beam CT, that may indicate intraprocedural success. Aim of our retrospective study was to analyze the usefulness of the "hug sign" at the intraprocedural unenhanced cone-beam CT as an early predictor of response to combined treatment, based on the hug sign angle.

Safety and efficacy of endoscopic ultrasound-guided radiofrequency ablation for pancreatic insulinoma: A single-center experience.

Background/objectives: Insulinomas are rare, functioning pancreatic neuroendocrine neoplasms (pNEN), whose gold standard therapy is surgical resection. Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) is a recent technique that has emerged as a minimally invasive therapeutic option for patients with pancreatic lesions not eligible for surgery. In this study, we aimed to describe a series of patients with unresectable pancreatic insulinoma treated with EUS-RFA.

COntrolling NUTritional Status (CONUT) as Predictive Score of Hospital Length of Stay (LOS) and Mortality: A Prospective Cohort Study in an Internal Medicine and Gastroenterology Unit in Italy.

Background: Hospital malnutrition affects nearly 30% of patients in medical wards and correlates with worse outcomes. An early assessment is necessary to stratify the risk of short-term outcomes and mortality. The predictive role of COntrolling NUTritional status (CONUT) score in this context has not yet been elucidated in Western countries.

Incidence and Impact of Refeeding Syndrome in an Internal Medicine and Gastroenterology Ward of an Italian Tertiary Referral Center: A Prospective Cohort Study.

Background: Refeeding syndrome (RS) is a neglected, potentially fatal syndrome that occurs in malnourished patients undergoing rapid nutritional replenishment after a period of fasting. The American Society for Parenteral and Enteral Nutrition (ASPEN) recently released new criteria for RS risk and diagnosis. Real-life data on its incidence are still limited.

Assessing Baveno VI criteria with liver stiffness measured using a new point-shear wave elastography technique (BAVElastPQ study).

Background And Aims: To date, no study has explored the potential role of ElastPQ, a novel point-SWE technique, in the assessment of clinically significant portal hypertension. The aim of our study was to determine a liver stiffness (LS) cut-off value measured by ElastPQ and laboratory parameters that could help to identify those patients who can safely avoid screening endoscopy.

Methods: Data were collected on 1422 patients who underwent ElastPQ measurement from January 2013 to January 2016 in our Department.

Contrast-Enhanced Ultrasound in the Short-Term Evaluation of Hepatocellular Carcinoma after Locoregional Treatment.

Background: Contrast-enhanced ultrasound (CEUS) with second-generation contrast agents performed 1 month after hepatocellular carcinoma (HCC) treatment is almost as sensitive as contrast-enhanced computed tomography (CECT) in depicting the residual tumor. However, the efficacy of CEUS performed early after the procedure is still debated.

Aim: We evaluated the diagnostic accuracy (DA) of CEUS for the assessment of tumor response shortly after locoregional therapy in patients with unresectable HCC.

Treatment of hepatocellular carcinoma in patients with portal vein tumor thrombosis: Beyond the known frontiers.

Hepatocellular carcinoma is one of the most frequent malignant tumors worldwide: Portal vein tumor thrombosis (PVTT) occurs in about 35%-50% of patients and represents a strong negative prognostic factor, due to the increased risk of tumor spread into the bloodstream, leading to a high recurrence risk. For this reason, it is a contraindication to liver transplantation and in several prognostic scores sorafenib represents its standard of care, due to its antiangiogenetic action, although it can grant only a poor prolongation of life expectancy. Recent scientific evidences lead to consider PVTT as a complex anatomical and clinical condition, including a wide range of patients with different prognosis and new treatment possibilities according to the degree of portal system involvement, tumor biological aggressiveness, complications caused by portal hypertension, patient's clinical features and tolerance to antineoplastic treatments.

Interventional oncology treatments for unresectable early stage HCC in patients with a high risk for intraprocedural bleeding: Is a single-step combined therapy safe and feasible?

Purpose: This study was designed to assess the feasibility and safety of a single-step combined therapy using radiofrequency ablation and transarterial chemoembolization (RFA + TACE) in patients with hepatocellular carcinoma (HCC) and uncontrolled coagulopathy. The study also aimed to compare the effectiveness of this approach with TACE alone, performed in a control group.

Material And Methods: One hundred and forty-three consecutive cirrhotic patients having a single HCC < 8 cm were enrolled in this observational prospective single-center study from January 2010 to June 2017 and were divided, according to coagulation tests, into three groups (A: low risk; B: intermediate risk and C: high risk of bleeding).

Regorafenib: a promising treatment for hepatocellular carcinoma.

: Hepatocellular carcinoma (HCC) is one of the most frequent malignant tumors with 854,000 new cases per year and represents the second most frequent cause of cancer-death. Despite surveillance, the number of patients that are diagnosed at a stage in which they are eligible for curative treatments ranges from 30% to 60%. Advanced HCC (BCLC-C) is characterized by a median survival of 6 months.

ACE I allele is associated with more severe portal hypertension in patients with liver cirrhosis: A pilot study.

Background: In liver cirrhosis, the renin-angiotensin-aldosterone system is involved in the pathogenesis of portal hypertension. Its effector, angiotensin II, is generated by angiotensin-converting enzyme (ACE). Serum ACE levels are affected by I/D polymorphism of its gene, with alleles I and D being associated, respectively, with lesser and greater activity of the enzyme.

Reverse time-dependent effect of alphafetoprotein and disease control on survival of patients with Barcelona Clinic Liver Cancer stage C hepatocellular carcinoma.

Aim: To characterize the survival of cirrhotic patients with Barcelona Clinic Liver Cancer (BCLC) stage C hepatocellular carcinoma (HCC) and to ascertain the factors predicting the achievement of disease control (DC).

Methods: The cirrhotic patients with BCLC stage C HCC evaluated by the Hepatocatt multidisciplinary group were subjected to the investigation. Demographic, clinical and tumor features, along with the best tumor response and overall survival were recorded.

A pilot study of capsule endoscopy after a standard meal for the detection and grading of oesophageal varices in cirrhotic patients.

Background: Capsule endoscopy has been proposed as an alternative to fibreoptic endoscopy for oesophageal varices evaluation in cirrhotics. However, it shows only moderate sensitivity compared to fibreoptic endoscopy.

Aim: To compare post-meal capsule endoscopy to fibreoptic endoscopy, based on the hypothesis that meal-induced increase of portal pressure can enhance its sensitivity.

Early prediction of response to sorafenib in patients with advanced hepatocellular carcinoma: the role of dynamic contrast enhanced ultrasound.

Background & Aims: Sorafenib has become the standard first-line treatment for patients with advanced HCC and acts by inducing alterations in tumor vascularity. We wanted to evaluate the feasibility of dynamic CEUS (D-CEUS) as a predictor of early tumor response to sorafenib and to correlate functional parameters with clinical efficacy end points.

Methods: Twenty-eight HCC patients treated with sorafenib 400mg bid were prospectively enrolled.

Gut microbiota and metabolic syndrome.

Symbiosis is the result of the relationship between gut microbiota and human surfaces; in fact, it regulates many functions such as metabolic and protective ones. It is widely known that any changes in the microbes in gut microbiota (dysbiosis) and the regulation of mucosal and systemic host's immunity have been linked to different diseases such as metabolic syndromes and associated disorders. Recent studies report an aberrant gut microbiota and an alteration of gut microbial metabolic activities in obese subjects, with an important influence of a number of human physiological functions.

Microscopic colitis.

Microscopic colitis may be defined as a clinical syndrome, of unknown etiology, consisting of chronic watery diarrhea, with no alterations in the large bowel at the endoscopic and radiologic evaluation. Therefore, a definitive diagnosis is only possible by histological analysis. The epidemiological impact of this disease has become increasingly clear in the last years, with most data coming from Western countries.

[Chronic hepatitis C virus infection: clinical picture and treatment possibilities].

It has been estimated that between 1.5 and 2 million people in Italy have anti-HCV antibodies. The vast majority are chronically infected with HCV and are unaware of the infection.

Patterns of chronic hepatitis B in Central Italy: a cross-sectional study.

We investigated the patterns of chronic hepatitis B virus (HBV)-related disease in a large cohort of HBsAg-positive patients, in Central Italy, by collecting a screening form with demographic, clinical and laboratory data. Overall, 737 HBsAg-positive cases were included (70% male; median age 52 years): 30% were inactive HBsAg carriers, 51% had chronic hepatitis B (CHB) and 19% had HBV-related cirrhosis. Patients from non-European Union (EU) countries (n = 65) were significantly younger, had a higher prevalence of HBeAg-positive infection and hepatitis delta virus (HDV) co-infection than patients of Italian origin.

Peginterferon alfa-2b and ribavirin in patients with hepatitis C virus and decompensated cirrhosis: a controlled study.

Background/aim: To evaluate long-term outcomes in decompensated HCV-related cirrhotic patients treated with antiviral therapy.

Methods: Of 129 eligible patients, 66 received peginterferon alfa-2b and ribavirin for 24 weeks, and 63 were controls. Survival and recurrence of liver failure events after therapy were main outcomes.

Effects of a single, short intravenous dose of acetyl-L-carnitine on pattern-reversal visual-evoked potentials in cirrhotic patients with hepatic encephalopathy.

1. In animals and in cultured neurons, L-carnitine and acetyl-L-carnitine (ALCAR) have been shown to counteract some of the toxic effects of ammonia. In order to detect similar properties in humans, we studied neuronal function after ALCAR administration in cirrhotics with hepatic encephalopathy (HE).
