Stool tagging applied in thin-slice multidetector computed tomography colonography
No full textObjective: To compare thin-slice multidetector computed tomography colonography (CTC) that uses stool tagging with colonoscopy. Method: One hundred fifty patients scheduled for colonoscopy underwent highresolution CTC. An iodinated contrast agent was added to the preparation to tag the residual colonic fluid and stool. The effect of fluid tagging was assessed first. Sensitivity and specificity were calculated for two independent readers. In addition, values were recalculated separately for the first and last 75 patients. Results: Tagging was optimal in 95.3% of the cases, and reader confidence was high. Sensitivities were 64.1%-66.7% (for the 2 readers) for 5- to 9-mm polyps and 91.7% for larger polyps. The overall specificity was 94.2% and 95%. Sensitivity improved during the study for both 5- to 9-mm polyps (from 54.2%-58.3% to 80%) and polyps larger than 9 mm (from 50% to 100%). Specificity changed nonuniformly. Conclusion: The combination of fluid tagging and high-resolution scanning in CTC showed high sensitivity and specificity, especially concerning sensitivity for polyps of 10 mm and larger
13. ESMO Weltkongress Gastrointestinale Tumoren: Die Entwicklung zielgerichteter Therapien im Blick
No full textDer 13. Weltkongress zu gastrointestinalen Tumoren stand in diesem Jahr unter der Leitung von Mario Dicato, MD vom Luxembourg Medical Center und Eric Van Cutsem, MD, PhD, vom Universitätskrankenhaus Gasthuisber, Leuven, Belgien. Der Kongress thematisiert die Malignitäten aller Teile des Gastrointestinaltrakts sowie Aspekte, die im Zusammenhang mit der Betreuung von Patienten mit GI-Tumoren stehen, inklusive Screening, Diagnose und den neuesten Behandlungsoptionen für häufige und seltene Tumore, betonen Dicato und Van Cutsem in ihrem Geleitwort zum Kongress.</jats:p
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
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
State of the art of antiemetic therapy
No full textDespite relevant progress achieved in the last 30 years for the prevention of chemotherapy-induced emesis, nausea and vomiting continue to be among the most distressing adverse events induced by chemotherapy. Emesis is a complex phenomenon, and the precise mechanism by which chemotherapy induces nausea and vomiting is not well known. Many neurotransmitters are involved, and several antiemetic drugs are available. Complete control of vomiting could be achieved in about 70-90% of patients with a better combination of antiemetic drugs. Recently, international guidelines to prevent chemotherapy-induced nausea and vomiting have been updated, and it is very important to know these recommendations and to use them correctly in our clinical practice. However, several aspects of antiemetic therapy will be clarified in the coming years: the improvement of nausea control, the prophylaxis of emesis induced by oral therapies, and the prevention of emesis induced by chemoradiation therapy
