Evaluating ibrutinib for the treatment of relapsed/refractory marginal zone lymphoma
No full textIntroduction: Marginal zone lymphoma (MZL) is a heterogeneous disease with a wide range of possible frontline therapies depending on the subtype; there are no shared guidelines for the treatment of relapsed/refractory MZLs. The growing evidence of the importance of the BCR pathway in the pathogenesis of B lymphoproliferative forms has led researchers to consider BTK as a potential therapeutic target in MZL. Area covered: The authors provide the reader with an evaluation of ibrutinib as a treatment option for refractory marginal zone lymphoma. The review includes an overview of the drug’s pharmacokinetics and pharmacodynamics, efficacy, and safety. The authors also provide the reader with their expert perspectives on the drug and its place in the treatment of MZL. Expert opinion: The availability of new non-chemotherapeutic agents represents an important opportunity to spare excessive exposure to cytotoxic compounds. Immunomodulators and targeted agents, alone or often in combination with immunotherapy, have been shown to be effective and safe therapies in patients with relapsed/refractory (R/R) MZL. In addition, numerous studies involving new generation targeted agents, alone or in combination, are currently active in both R/R and untreated patient populations, some with encouraging preliminary results
Diagnosis and management of prefibrotic myelofibrosis.
No full textThe 2016 WHO classification comprises two stages of primary myelofibrosis (PMF): early/prefibrotic primary myelofibrosis (pre-PMF) and overt fibrotic PMF (overt PMF). Diagnostic criteria rely on bone marrow morphology, fibrosis grade (0-1 in pre-PMF, 2-3 in overt PMF), and clinical features (leukoerythroblastosis, anemia, leucocytosis, increased lactate dehydrogenase, and palpable splenomegaly). An accurate differentiation from essential thrombocythemia (ET) is pivotal because the two entities show different clinical presentation and outcome, in terms of survival, leukemic evolution, and rates of progression to overt myelofibrosis. Areas covered: The current review provides an overview on how to diagnose and stratify patients with pre-PMF, taking into account their definite and peculiar risk of vascular event, which is often neglected, and their milder disease course, compared with overt PMF, with the aim of improving and individualizing their counseling and management. Expert commentary: Pre-PMF is a new entity characterized by a unique combination of both a thrombo-hemorrhagic risk (that brings it closer to PV and ET) and a definite risk of disease evolution (that places pre-PMF somewhat closer to the overt PMF variant)
Pregnancy outcome and management of 25 pregnancies in women with polycythemia vera.
No full textOur data confirm that pregnant women with PVhave an increased risk of fetal loss. The high rate of advanced miscar-riage, related to the presence ofJAK2V617F mutation, seems to bereduced by anti-thrombotic therapy. The correct use of vene-section has to be established in this setting of patients. Due to the rar-ity of this condition, collaborative studies are required to better clarifythe best management of pregnancy in 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
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
