Carcinoma anal associado aos trajectos fistulosos da doença de Crohn
No full textTrabalho Final do Curso de Mestrado Integrado em Medicina, Faculdade de Medicina, Universidade de Lisboa, 2017As neoplasias malignas que surgem a partir das fístulas perianais associadas à D. Crohn são raras. No entanto, é uma patologia com mau prognóstico por ser diagnosticada tardiamente com doença avançada. Uma das principais questões é não haver guidelines de vigilância e tratamento.
O objectivo deste trabalho é indicar as características clínicas dos doentes do Hospital Santa Maria (HSM), que desenvolveram neoplasia perianal num trajecto fistuloso e compará-las com a literatura.
O diagnóstico dos nossos doentes foi tardio, sendo que a maioria obtiveram o diagnóstico por exame extemporâneo enquanto fizeram a ressecção abdomino-perineal com colostomia de derivação.
Por ser uma patologia rara, não existem guidelines de vigilância por ausência de estudos prospectivos significativos. No entanto, é uma doença diagnosticada tardiamente, com mau prognóstico e com impacto significativo na qualidade de vida dos doentes após o tratamento. Portanto apesar de ser uma patologia rara, é merecedora de uma atenção prospectiva para clarificar os procedimentos a efectuar.Cancer arising from Chron's disease associated perianal fistulae is rare. Nevertheless, it has poor prognosis due to its late diagnosis. One of the main issues is that specific vigilance and treatment guidelines are non-existant.
The aim of this final work is to refer the clinical aspects and characteristics of Hospital Santa Maria's patients who developed fistulae-associated perianal neoplasies and to compare them with the available literature.
Our patients' diagnosis was late and most of them were made during the abdomino-perianal resection.
Due to its rarity, there are no specific guidelines regarding vigilance since there are no significant prospective studies. This condition's late diagnosis and its poor prognosis negatively impact on the patients' post-treatment quality of life. Therefore, the main focus should reside on which procedures are to be performed

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
