Management of Hepatic Encephalopathy as an Inpatient
No full textThis review is limited to the management of inpatients with clinically overt hepatic encephalopathy (HE) due to cirrhosis.1 Type C overt HE should be divided into episodic
HE (when the symptoms develop over a short period and fluctuate in severity), recurrent HE (characterized by bouts of HE within a time interval of 6 months or less), or persistent
HE (with continuous behavioral or neurological symptoms). Another important distinction is between spontaneous and precipitated HE, the latter induced by a specific and
clearly identifiable precipitating event. The above taxonomy of overt HE (episodic versus recurrent versus persistent, precipitated versus spontaneously occurring) is clinically relevant because the diagnostic procedures and management of each category differ

Emerging issues in the use of transjugular intrahepatic portosystemic shunt (TIPS) for management of portal hypertension: Time to update the guidelines?
No full textSince its first introduction in the 1980s, transjugular intrahepatic portosystemic shunt has played an increasingly important role in the management and treatment of the complications of portal hypertension. In 2005, the American Association for the Study of Liver Diseases published the Practice Guidelines for the use of transjugular intrahepatic portosystemic shunt in the management of portal hypertension. Since then, technical advances and new interesting data on transjugular intrahepatic portosystemic shunt have been presented in the literature. The present review focusses on the applications of transjugular intrahepatic portosystemic shunt and examines more recent studies on this topic; the current guidelines on the use of transjugular intrahepatic portosystemic shunt are also discussed. From the data presented in the most recent publications, it has become increasingly clear that the recommendations stemming from the current guidelines need to be reviewed and updated in several points. Changes in the American Association for the Study of Liver Diseases Practice Guidelines are needed for both common indications (variceal bleeding and refractory ascites) as well as uncommon ones (i.e.. Budd-Chiari syndrome and portal cavernoma). In addition, a relevant technical advance has been the introduction of the polytetrafluoroethylene-covered stents, which greatly improved the patency and clinical efficacy of transjugular intrahepatic portosystemic shunt. Consequently, new studies are required to re-assess the role of transjugular intrahepatic portosystemic shunt performed with new covered stents as compared with other strategies in the management of portal hypertension.

Nutritional Status and Liver Transplantation
No full textChronic liver disease has a profound effect on nutritional status and undernourishment is almost universally present in patients with end-stage liver disease undergoing liver transplantation. In the last decades, due to epidemiological changes, a trend showing an increase in patients with end-stage liver disease and associated obesity has also been reported in developed countries. Nutrition abnormalities may influence the outcome after transplantation therefore, the importance to carefully assess the nutritional status in the work-up of patients candidates for liver transplantation is widely accepted. More attention has been given to malnourished patients as they represent the greater number. The subjective global nutritional assessment and anthropometric measurements are recognized in current guidelines to be adequate in identifying those patients at risk of malnutrition. Cirrhotic patients with a depletion in lean body mass and fat deposits have an increased surgical risk and malnutrition may impact on morbidity, mortality and costs in the post-transplantation setting. For this reason an adequate calorie and protein intake should always be ensured to malnourished cirrhotic patient either through the diet, or using oral nutritional supplements or by enteral or parenteral nutrition although studies supporting the efficacy of nutritional supplementation in improving the clinical outcomes after transplantation are still scarce. When liver function is restored, an amelioration in the nutritional status is expected. After liver transplantation in fact dietary intake rapidly normalizes and fat mass is progressively regained while the recovery of muscle mass can be slower. In some patients unregulated weight gain may lead to over-nutrition and may favor metabolic disorders (hypertension, hyperglycemia, hyperlipidemia). This condition, defined as 'metabolic syndrome', may play a negative role on the overall survival of liver transplant patients. In this report we review data on nutrition and liver transplantation. © 2011 INASL
May sarcopenia and/or hepatic encephalopathy improve the predictivity of model for end-stage liver disease?
No full textWe read with interest the recent study by van Vugtet al.1whichadds data to the debate on a desirable improvement in thepolicy for the optimization of the organ allocation criteria inliver transplant (LT) setting.The aim of this multicenter registry based European studywas initially to investigate whether sarcopenia is a risk factor,independent of the model for end-stage liver disease (MELD)score, for waiting list mortality
Beta-blokers in patients with cirrhosis and infection: don't blame too soon.
Full text linkWe found that PPI-users had a higher rate and BBs-users a lower rate of infections. The lower infection rate and better prognosis of BB-users can not be attributed, as suggested by Schiavon et al., to a higher proportion of variceal bleeding in this group; in fact, the large majority of patients hospitalized for bleeding were excluded from the study as they came to our ward already on systemic antibiotic treatment (which is usually started in the Emergency room) and this would have represented a confounding factor. Only few patients with variceal bleeding were included: they developed bleeding after enrolment and were equally distributed between those taking and not taking BBs. Following the recent debate about the ‘therapeutic window’ of BBs in cirrhotic patients (2–4), we were also interested in evaluating possible harmful effects of BBs in cirrhotic patients with infections. This was a secondary aim of our study and we certainly recognize that the study was underpowered for this purpose
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
