    tIn recent years, epidemiological, clinical, and biological evidence has drawn the attention on the influenceof sex and gender on Alzheimer’s disease (AD). Nevertheless, not enough attention has been paid totheir impact on treatment outcomes. The present study is aimed at systematically retrieve, review anddiscuss data coming from available randomized placebo-controlled trials (RCTs) on currently marketedtreatments for AD (i.e., cholinesterase inhibitors [ChEIs] and memantine) in order to describe possiblesex and gender differences in their efficacy, safety and tolerability.A systematic review of literature was performed. None of the retrieved studies reported data on theefficacy, safety and tolerability of considered medications separately in male and female patients withAD. We thus analyzed 48 excluded studies of potential interest, that is, almost all of the currently availabletrials on the four considered drugs. Nearly all the considered RCTs recruited a larger number of femaleparticipants to mirror the sexually unbalanced prevalence of AD. Only two studies took into account thepotential influence of sex and gender on treatment efficacy, reporting no significant differences betweenmen and women. None of the studies investigated potential sex and gender differences in the safety andtolerability of the four considered treatments.The existence of sex and gender differences in the efficacy and tolerability of ChEIs and memantine inAD has, to date, drawn limited to no attention. However, a considerable amount of data, with an adequaterepresentativeness in terms of sex/gender distribution, seem to be already available for dedicated anal-yses on this topic. A greater effort should be made to collect and report data on those factors interactingwith sex and gender that may significantly influence clinical manifestations, outcomes, and trajectoriesover time of AD patients

    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

    Multimodal analgesic strategies in polytraumatized patients

    No full text
    In recent years, the resuscitation of trauma patients has improved; however, pain related to trauma remains associated with systemic complications. In trauma patients, pain should be considered a vital sign, and its control is crucial for reducing complications, improving patient satisfaction, and enhancing the quality of life. The multimodal analgesia approach is the mainstay in pain control, and growing evidence in the literature supports a greater role of regional anesthesia in the management of trauma casualties. In this review, we offer the reader an updated general framework of the various approaches available for pain treatment in polytraumatized patients, with a focus on the opportunities presented by regional anesthesia. We will examine different types of locoregional anesthesia blocks and describe ultrasonographic execution techniques

    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

    Full text link
    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

    Full text link
    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

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    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
