Twelve months of treatment with octreotide-LAR reduces joint thickness in acromegaly
No full textOBJECTIVE: To evaluate the role of age, gender, duration and control of acromegaly on the reversibility of arthropathy. PATIENTS AND DESIGN: 30 de novo patients with active acromegaly, 30 cured patients and 30 healthy subjects were studied in a tranverse and an open longitudinal study design. METHODS: Shoulder, wrist and knee thickening was measured by ultrasonography at study entry in all 90 subjects and after 12 Months of treatment with octreotide-LAR (OCT-LAR) at a dose of 10-40 mg every 28 days in the 30 de novo patients. RESULTS: Thickness at all joint sites was greater in the active than in the cured patients and controls (P10 Years. Age significantly correlated with wrist (r=-0.55; P<0.001), right knee (r=-0.45; P=0.01), and left knee thickness (r=-0.42; P=0.02) in patients with active disease, and with wrist thickness (r=0.88; P<0.0001) in controls. Twelve Months of OCT-LAR treatment led to disease control in 18 patients (60%). There was a decrease in the thickness of the shoulder (15.1+/-3.2%), wrist (20.5+/-3.1%), right knee (22.2+/-3.4%) and left knee (18.2+/-2.8%) in all patients but the reduction in joint thickness at all sites was greater in the patients with controlled disease after OCT-LAR treatment than in the uncontrolled patients (P<0.01). Shoulder and right knee thickening normalized in respectively 11 (61.1%) and 16 (88.9%) well-controlled patients. CONCLUSIONS: Growth hormone and insulin-like growth factor-I (IGF-I) suppression by 12 Months' OCT-LAR treatment is accompanied by a significant decrease in the thickness of both weight-bearing and non-weight-bearing joints (mainly in patients whose disease is controlled) regardless of disease duration. These findings suggest that tIssue hypertrophy in the context of the acromegalic arthropathy can be improved by suppressing IGF-I levels
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
