Comparative StudySurvival comparison between surgical resection and radiofrequency ablation for patients in BCLC very early/early stage hepatocellular carcinoma.
To compare the survival between surgical resection (SR) and radiofrequency ablation (RFA) in patients with hepatocellular carcinoma (HCC) in Barcelona Clinic Liver Cancer (BCLC) very early/early stage. ⋯ For HCC patients in BCLC very early/early stage, there was no significant difference in OS between SR and RFA. However, SR yielded better DFS than RFA.

Cirrhotic patients are prone to develop life-threatening complications that require emergency care and ICU admission. They can present specific decompensations related to cirrhosis such as variceal bleeding and hepatorenal syndrome (HRS) or other critical events also observed in the general population such as severe sepsis or septic shock. Clinical management of all these entities requires a specific approach in cirrhosis. ⋯ Cirrhotic patients are also at a high risk for development of other bleeding complications and are more susceptible to nosocomial infections. This extreme complexity of critically-ill cirrhotic patients requires a specific medical approach that should be known by general intensivists since it has a negative impact on patient prognosis. This review will focus on the diagnostic approach and treatment strategies currently recommended in the critical care management of patients with cirrhosis.

Resolution of the three-dimensional structures of several hepatitis C virus (HCV) proteins, together with the development of replicative cell culture systems, has led to the identification of a number of potential targets for direct-acting antiviral (DAA) agents. Numerous families of drugs that potently inhibit the HCV lifecycle in vitro have been identified, and some of these molecules have reached early to late clinical development. Two NS3/4A protease inhibitors, telaprevir and boceprevir, were approved in Europe and the United States in 2011 in combination with pegylated interferon (IFN)-α and ribavirin for the treatment of chronic hepatitis C related to HCV genotype 1, in both treatment-naïve and treatment-experienced patients. ⋯ They include second-wave, first-generation, and second-generation NS3/4A protease inhibitors, nucleoside/nucleotide analogue inhibitors and non-nucleoside inhibitorsof HCVRNA-dependent RNA polymerase, inhibitors of nonstructural protein 5A (NS5A) and host-targeted compounds, such as cyclophilin inhibitors and silibinin. The proof of concept that IFN-free regimens may lead to HCV eradication has recently been brought. However, new drugs may be associated with troublesome side effects and drugdrug interactions, and the ideal IFN-free DAA combination remains to be found.

Chronic intermittent hypoxia is a major trigger for non-alcoholic fatty liver disease in morbid obese.
Morbid obesity is frequently associated with low grade systemic inflammation, increased macrophage accumulation in adipose tissue (AT), obstructive sleep apnea (OSA), and nonalcoholic fatty liver disease (NAFLD). It has been suggested that chronic intermittent hypoxia (CIH) resulting from OSA could be an independent factor for early stage of NAFLD in addition to other well-recognized factors (dyslipidemia or insulin resistance). Moreover, macrophage accumulation in AT is associated with local hypoxia in fat tissue. We hypothesized that the association between CIH and morbid obesity could exert additional specific deleterious effects both in the liver and adipose tissues. ⋯ In morbidly obese patients, CIH was strongly associated with more severe liver injuries but did not worsen obesity induced macrophage accumulation in adipose tissue depots.

Prospective evaluation of the prognostic scores for cirrhotic patients admitted to an intensive care unit.
Cirrhotic patients admitted to an Intensive Care Unit (ICU) have a poor prognosis. Identifying patients in whom ICU care will be useful can be challenging. The aim of this study was to assess the predictive value of prognostic scores with respect to mortality and to identify mortality risk factors. ⋯ For cirrhotic patients admitted to the ICU, SAPS II, and SOFA scores predicted ICU mortality better than liver-specific scores. Mechanical ventilation or vasopressor therapy, bilirubin levels at admission and infection in patients with advanced cirrhosis were associated with a poor outcome.
