Complications after surgery for gastric cancer
No full textThe improvement in surgical and anasthesiological techniques have allowed a reduction in oncological surgical morbidity and mortality. The objective of this retrospective study is to evaluate the morbidity and the mortality in oncological gastric surgery up to date. Between 1979 and 1994 we evaluated 281 patients for gastric cancer, of whom 249 underwent surgery. The patients ranged in age from 34 to 88 years, with a mean age of 67,8 years, and included 158 males and 91 females. An oncological radical excision was performed in 184 patients (122 gastroresections and 62 gastrectomies). The other 65 patients underwent exploratory or palliative surgery: 26 explorative laparotomies, 26 gastroenteroanastomoses, 9 gastroresections, 3 digiunostomies and one gastrostomy. The overall post-operative morbidity has been 40,1%, 27,3% was generical and 12,8% was surgical morbidity. The overall mortality has been 9,6%, of whom about one third following surgical complications. In our experience the factors related with morbidity and mortality have been: age, preoperative nutritional state and stage of the disease
Giorno e Notte: le città di Babele
Full text linkThis paper aims to start a reflection on the double and ambiguous identity of the cities. On one side, the “public face” of labour towns, made by work, social organization and public relations. A face that is characterized by productive efficiency and the “politically correct”. On the other side, instead, the “dark face” of the cities represented by the various features of marginality and exclusion, of the borderline relations, sometimes close or beyond the borders of law. Night and day, that coexist and take turns, and marked the city life without a break. The reassuring pulse of the chaos of the working city, opposed to the night time of silence and solitude, of anxiety, revelation, and lust. Night and day that overlap, although they’re the result of the ambiguity of human being. A contradiction that unveils and conceals the soul and that produce ambiguous behaviours, not always accepted by the social rules. The authors try to direct a multitude of multidisciplinary suggestions into a historiographical path, obviously awake that – at the present state-of-art – we are just talking of a first temporary palimpsest
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
ANCA-Associated Vasculitis
No full textANCA-associated vasculitis (AAV) is a group of disorders characterized by inflammation affecting small blood vessels. AAV includes microscopic polyangiitis (MPA), granulomatosis with polyangiitis (GPA, formerly Wegener’s granulomatosis), and eosinophilic granulomatosis with polyangiitis (EGPA, formerly Churg-Strauss syndrome). AAV can be considered a complex disease; in fact, both genetic and environmental factors are involved in its susceptibility. To improve the understanding of the disease, the genetic component has been extensively studied by candidate-gene and genome-wide association studies. Most of the identified genetic AAV risk factors are common variants, whose functional importance still needs further investigation. In this chapter, we discuss the results of genetic studies in AAV. We also present novel approaches to identify the causal variants in complex susceptibility loci and disease mechanisms. Finally, we discuss the challenges in translating genomic data into clinical practice
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
