Caregiver’s psychological well-being and quality of relationship with cardiac amyloidosis patients
No full textCaregivers’ psychological well-being is linked to the quality of care provided for familiar with chronic illness. Despite caregivers of cardiac patients present an impaired psychological well-being, less investigated is the psychological well-being of caregivers of individuals with a rare disease such as the Transthyretin Cardiac Amyloidosis (ATTR-CA). Specifically, given that no study explored the well-being of the caregiver and the caregiver-patient relationship, this study aimed to analyze the prevalence of anxiety and depression in ATTR-CA caregivers and if these disorders were associated with patient’s and caregiver’s characteristics. Fifty-eight dyad caregiver-ATTR-CA patients completed the Hospital Anxiety and Depression Scale and the Network of Relationships Inventory. Moreover, ATTR-CA patients completed the Kansas City Cardiomyopathy Questionnaire, while caregivers completed the Multidimensional Scale of Social Support. Results showed that anxious caregivers (44%) reported higher conflict with patients. They had ATTR-CA relatives with a worse perception of cardiac symptoms and higher anxiety and depression. Depressed caregivers (39%) reported higher conflict with ATTR-CA relatives and lower perceived social support. Caregiver reported a high prevalence of anxiety and depression associated with worse personal relational well-being and to patient’s psycho-physical condition. The care of ATTR-CA patient should consider the caregiver well-being
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
Bilateal renal carcinoma: The results of conservative surgery and the prognostic significance of synchronous and metachronous forms
No full textNonspecific granulomatous prostatis (PGA): Diagnosis and follow-up
No full textA series of 22 cases of nonspecific granulomatous prostatitis (NGP) is presented. Patients were seen between 1976 and 1990. In 8 cases the clinical picture upon presentation was that of an acute inflammatory process of the lower urinary tract; 10 patients had obstructive symptoms from prostatic enlargement; in 4 cases NGP was an incidental clinical finding. In 19 out of 22 patients rectal examination led to suspect prostatic cancer, and prostatic biopsy was necessary for diagnosis. On the whole, 13 patients were followed for 1-15 years after initial diagnosis (mean: 5 years). In 12 out of 13 cases, rectal examination was found to be normal during follow-up. One patient was submitted to a second prostatic biopsy 11 years after the initial evaluation: diagnosis of NGP was confirmed. In 7 cases, transrectal ultrasound was part of the diagnostic evaluation; additionally, 10 patients had one or more ultrasound examinations during follow-up. Ultrasonographic features were aspecific in all instances, and did not provide conclusive diagnostic information
