Autoimmune hemolytic anemia in Philadelphia positive chronic myeloid leukemia with t(7;14) anomaly after 5 years of interferon alpha treatment
No full textKarakus, sema/0000-0001-7615-4581; Haznedaroglu, Ibrahim C./0000-0001-8028-9462; Haznedaroglu, Ibrahim C./0000-0001-8028-9462A 41-year-old woman, Philadelphia positive chronic myeloid leukemia patient, had progressive decline in hemoglobin levels. She had been receiving interferon alpha treatment for five years. Autoimmune hemolytic anemia was diagnosed. Subsequent bone marrow examination revealed translocation t(7;14). She was placed on prednisone treatment. The patient responded to prednisone as treatment for the hemolytic process. The result of a direct Coombs' test remained positive. The patient died shortly after the diagnosis of autoimmune hemolytic anemia. Autoimmune hemolytic anemia should be considered in the evaluation of chronic myeloid leukemia patients with a sudden decrease in hemoglobin levels
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
Current concerns of undertreatment and overtreatment in chronic myeloid leukemia based on European LeukemiaNet 2013 recommendations
No full textIntroduction: The aim of this paper is to indicate optimal tyrosine kinase inhibitor (TKI) administration practices based on European LeukemiaNet (ELN) 2013 recommendations for chronic myeloid leukemia (CML). Likewise, current concerns of undertreatment and overtreatment with TKIs during the long-term clinical course of CML will be outlined
The therapeutic goals of essential thrombocythemia under the clouds of over-treatment and under-treatment
No full textIntroduction: Therapeutic stratification after the accurate essential thrombocythemia (ET) diagnosis is made based on the medical history (age, previous thrombosis), clinical assessments (cardiovascular [CV] risk factors, comorbidities, systemic diseases), laboratory examinations (leukocytosis, extreme thrombocytosis, anemia) and if available further sophistical analyses (CD34 count, JAK2V617F homozygosity, and mutant allele burden)
