How could patient reported outcomes improve patient management in chronic myeloid leukemia?
Full text linkIntroduction: Patients reported outcome (PRO) are still under-used in patients with chronic myeloid leukemia (CML) treated with tyrosine kinase inhibitors (TKIs), though data on the correlation between quality of life (QoL) and therapeutic efficacy are increasingly known. Chronic low-grade toxicities can reduce patient's QoL and negatively impact on adherence.Areas covered: This review will focus on the role of QoL questionnaires in patients with CML, receiving imatinib or newer TKIs (dasatinib, nilotinib, bosutinib, ponatinib). Physicians tend to underestimate the impact of TKI-related symptoms, in particular fatigue, that negatively affect QoL and can be a reason of poor adherence to therapy, with detrimental effect on long-term response. Few studies pointed out the role of PRO in CML, and there is paucity of questionnaires specifically designed for CML patients.Expert commentary: We recommend a wider use of PRO to join the pursuit of a rapid and deep responses with an optimization of QoL

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
Clinical presentation, outcome and risk factors of late-onset non-infectious pulmonary complication after allogeneic transplantation
No full textThe term late-onset non-infectious pulmonary complications (LONIPCs) has been used to refer to events occurring later than 3 months after allogeneic hematopoietic stem transplant (HSCT), such as bronchiolitis obliterans, bronchiolitis obliterans with organizing pneumonia, and lymphocytic or idiopathic interstitial pneumonia. The incidence of LONIPCs varies widely, ranging between 10% and 26%. Median time for LONIPC development is about 8-12 months after HSCT. Clinical symptoms may be insidious and non specific at the beginning and can be present in different types of infections. The diagnosis is made on the basis of thoracic high-resolution computed tomography and pulmonary function tests (PFT). It usually requires that standard cultures for infective agents on bronchoalveolar lavage are negative and is confirmed by transbronchial or lung biopsy, whenever possible. Total body irradiation and high doses of drugs used in the conditioning regimens , HLA disparity between donor and recipient, and chronic graft-versus-host disease (GVHD) are the main risk factors for LONIPCs. Since patients with LONIPCs have an increased risk of mortality because of infections or respiratory failure, pre- and post-transplant PFTs are strongly recommended in order to timely identify affected patients. The administration of antithymocyte globulin before unrelated donor transplants and slow taper of cyclosporine after transplant have been shown to prevent chronic GVHD and, therefore, the occurrence of LONIPC

No full textDispelling 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
