Clinical outcome of 149 patients with polymyalgia rheumatica and giant cell arteritis
No full textObjective. To assess the clinical outcome of patients with polymyalgia rheumatica (PMR) and giant cell arteritis (GCA). Methods. All charts of consecutive patients with a diagnosis of PMR and/or GCA attending a tertiary referral center from June 1989 to February 1996 were reviewed following a predetermined protocol. Subsequently, the majority of patients (90%) were assessed clinically or by telephone interview. Registered variables included demographic data, disease characteristics, prednisone dosage and duration, comorbidities, and clinical outcomes. Results. There were 149 patients (133 with PMR alone, 7 with GCA alone, 9 with both); 94 (63%) were females; the mean age was 68 9 years, and the mean disease duration from the first symptom to the rheumatology consultation was 13 12 weeks (1-99). Typical clinical features of PMR were present in patients with PMR. Synovitis was observed in 26 patients. The presenting symptoms for GCA were typical features in 13 patients and blindness in 3 (2%) patients. Mean follow-up was 3.7 2 years. Comorbid conditions were present in 71 patients: 12 patients had hypertension, 13 had fractures, 8 diabetes, 29 cataract, 8 major infection, and 37 had other complications. Cancer was diagnosed in 4 patients and 6 patients had died. Prednisone was prescribed in 148 patients (mean dose 23 14 mg) for a mean time of 28 29 mo. Nonsteroidal antiinflammatory drugs were prescribed in 51 (34%) patients and methotrexate in 2. Disease remission was achieved in 81 (54%) patients (72 remissions, 9 presumed remissions) in whom steroid therapy had been stopped. Another 54 (36%) patients were still taking prednisone at the time of the interview, all were in clinical remission. Seventeen patients developed rheumatoid arthritis subsequent to the diagnosis of PMR. Conclusion. PMR and GCA should not necessarily be considered diseases with favorable outcome. In many of our patients, steroids were required for a prolonged period. Some patients developed significant complications attributable to steroid therapy. A significant number of patients progressed to rheumatoid arthritis

There were 149 patients (133 with PMR alone, 7 with GCA alone, 9 with both); 94 (63%) were females; the mean age was 68 ± 9 years, and the mean disease duration from the first symptom to the rheumatology consultation was 13 ± 12 weeks (1-99). Typical clinical features of PMR were present in patients with PMR. Synovitis was observed in 26 patients. The presenting symptoms for GCA were typical features in 13 patients and blindness in 3 (2%) patients. Mean follow-up was 3.7 ± 2 years.

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
Beyond the joints: Neurological involvement in rheumatoid arthritis
No full textAlthough arthritis is the most notable component, rheumatoid arthritis (RA) is a systemic inflammatory disorder where extra-articular manifestations are common; among them, central and peripheral nervous system involvement is frequent and associated with significant morbidity and, in some cases, reduced life span. It may produce a myriad of symptoms and signs ranging from subtle numbness in a hand, to quadriparesis and sudden death. Central and peripheral neurologic manifestations may arise from structural damage produced by RA in diarthroidal joints, by the systemic inflammatory process of the disease itself or by the drugs used to treat it. Neurologic syndromes may appear suddenly or developed slowly through months, and emerge early or after years of having RA. Neurologic manifestations may be easily overlooked or incorrectly assigned to peripheral arthritis unless the attending physician is aware of these complications. In this article, we review neurologic involvement in RA patients with emphasis on clinical approach for early detection. Zapotitlán 2011 Clinical Rheumatology
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
