Analysis of Clinical Relevance and Predictive Factors for Postoperative Ascites after Liver Resection for Hepatocellular Carcinoma with Actual Long-Term Survival Analysis
No full textBackground: Ascites is one of the most common complications after liver resection. Although it is not generally considered to be an expression of postoperative liver failure, it is commonly associated with an increased rate of postoperative mortality. Objective: We evaluated the predictive factors and the clinical relevance of postoperative ascites, both for early and long-term results, using actuarial and actual long-term survival analysis. Materials and methods: A retrospective evaluation of 325 unselected and consecutive patients who received liver resection with hepatocellular carcinoma (HCC) was carried out. Overall survival and disease free survival according to the occurrence of postoperative ascites were computed. Results: No features linked to the technical aspect of the resection had a predictive value. The only feature related to the tumor was the posterior location of HCC. In the subgroup of cirrhotic patients with a posterior-side HCC, the rate of ascites was 34.9%; 51 out of 57 patients with ascites (89.5%) presented a posteriorly located HCC in cirrhosis. Roughly one-fifth of patients with postoperative ascites presented signs of liver failure, but in-hospital mortality was almost four-fold that of patients without ascites. Conclusion: A posterior location of HCC significantly increased the risk of ascites

Beyond Lymph Nodes: Splenectomy, Bursectomy and Omentectomy
No full textWe will discuss here the role of splenectomy, bursectomy and omentectomy in the light of recent literature, taking as a starting point the indications reported by the most important guidelines: those from the Italian Research Group for Gastric Cancer (2015) and from the Japanese Gastric Cancer Association (2018). Splenectomy is indicated in cases of advanced gastric cancer with infiltration of the spleen or the pancreas. Despite the fact that 8–28% of proximal third gastric cancers metastasize to the splenic hilum nodes, the role of splenectomy as a facilitator of station 10 clearance is controversial and should be considered on condition that it can be conducted safely. Bursectomy is no longer supported as a technique increasing surgical cure rates. Still, it may have a role in selected patients candidate to non-standard multimodal management of stage IV gastric cancer. Omentectomy has always been part of curative gastrectomy in order to ensure control of micrometastases. However, the recent literature discusses this role and consensus regarding its real benefit seems lost
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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
