The experience of a cardiologist and of an internist in taking charge and care of patients from other cultures from a gender perspective. the yemen project
No full textViene illustrata l’esperienza di un cardiologo e diuna internista in Yemen, con istantanee dalla vita quotidiana, dentro e fuori gli ospedali. Dopo avere ripercorso le tappe principali della cooperazione Italia-Yemen, viene descrittala situazione della sanità yemenita, con particolare riferimento ai suoi ospedali e alla preparazione del personale medico e alle differenze di genere nell’approccio alle pazienti e ai pazienti. Vengono poi presi in considerazione alcuni aspetti caratterizzanti la stato di salute della popolazione dello Yemen, come l’altissima incidenza di cardiopatia reumatica a causa della mancanza totale di prevenzione primaria esecondaria e le differenze di genere nel trattamento delle donne con sindrome coronarica acuta.This paper illustrates the experience of a cardiologist and an internist in Yemen, with snapshots from everyday life, both inside and outside hospitals. After outlining the main stages of Italy-Yemen cooperation, it describes the situation of Yemeni health care, with particular reference to its hospitals, the training of medical personnel and gender differences in the approach to male and female patients. It then takes into consideration certain aspects characterising the state of health of the Yemeni population, such as the extremely high incidence of rheumatic heart disease due to the total lack of primary and secondary prevention and gender differences in the treatment of women with acute coronary syndrome
Biological and clinical effects of anti-TNFalpha treatment.
No full textTumor necrosis factor alpha (TNFalpha) is implicated in the pathogenesis of many chronic inflammatory diseases such as rheumatoid arthritis (RA), psoriasis and psoriatic arthritis (PsA), ankylosing spondylitis (AS), Crohn's disease, ulcerative colitis and uveitis. The availability of new pharmacological agents (infliximab, etanercept, adalimumab), able to selectively block the TNFalpha, has recently offered new opportunity for the treatment of these diseases. TNFalpha antagonists are different in the mechanism of action and are all effective agents in the treatment of RA and several chronic inflammatory diseases as a large number of controlled clinical trials have shown. Among biological effects of TNFalpha antagonists, the production of autoantibodies has been emphasized. This phenomenon is not correlated with the disease background, since anti-nuclear antibodies (ANA) and anti-double stranded-DNA antibodies (anti-dsDNA) induction is observed in RA as well as in spondyloarthritis (SpA) patients. Nonetheless, recent studies had reported a significant reduction in the serum titre of rheumatoid factor (RF) and/or anti-cyclic citrullinated peptide antibodies (anti-CCP) during anti-TNFalpha therapy. The TNFalpha antagonists represent a significant advance in the therapy of active RA and other chronic inflammatory diseases. However, they have distinct biological, clinical, and pharmacological properties that must be considered when selecting a drug for therapy
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
