    Treatment algorithm for oral anticoagulant and antiplatelet therapy in epistaxis patients

    No full text
    Background and objectives: There is currently little published guidance on the management of anticoagulant and antiplatelet medication in patients admitted with epistaxis. The routine practice of withholding such medication in an attempt to control the epistaxis is common in the UK. However, this practice is not evidence-based, is often unnecessary, and can be associated with significant morbidity. This study introduces a treatment algorithm for oral anticoagulant and antiplatelet therapy in epistaxis patients, validated through a completed audit cycle. Methods: One hundred patients admitted with epistaxis to the University Hospital Southampton NHS Foundation Trust were studied via a two-audit cycle covering the implementation of a new treatment algorithm formulated jointly by the otolaryngology and haematology departments. Results: On admission, 58 per cent of patients were taking some form of anticoagulant or antiplatelet medication. The number of patients having such medication withheld decreased significantly between the two audits, for all drugs studied (i.e. aspirin, clopidogrel and warfarin). There was no significant increase in re-bleeding or re-admission rates between the audits. Conclusion: Implementation of this treatment algorithm would help standardise management for epistaxis patients taking anticoagulant or antiplatelet drugs, and should reduce morbidity associated with unnecessary routine discontinuation of such medication

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    We 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

    A guide to new anticoagulant medications for ENT surgeons

    No full text
    Objectives: This study aimed to ascertain otolaryngologists' current knowledge of new (e.g. apixaban, rivaroxaban) and old (e.g. warfarin) anticoagulant medications, and to provide an educational overview of new anticoagulants for use by surgeons. Methods: A questionnaire survey was distributed across the Wessex region, UK, to ascertain the levels of knowledge of and confidence in managing patients taking various anticoagulants. In total, 50 questionnaires were completed (41 by trainees and 9 by consultants). A literature review of new anticoagulant medications was then conducted. Results: In general, there was poor clinical and pharmacokinetic knowledge of newly licensed anticoagulant medications. Respondents were more confident in the use of older vs newer forms of anticoagulants. This was true across all grades of doctors, but particularly at the senior level. All respondents stated that they would like to see an educational resource on anticoagulants. Conclusion: Knowledge of newly licensed anticoagulation medications is poor. This study has produced an educational resource for the management of anticoagulant agents. A thorough knowledge of these drugs is essential for the acute management of bleeding patients and in peri-operative surgical planning.</p

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    We 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
