No full textThe role of Proxelan in the treatment of chronic prostatitis. Results of a randomized trial.
No full textAIM:
Inflammatory diseases of the prostate are one of the most difficult problems to manage in the fertile male aged between 20 and 50. Antibiotics are the gold standard for the treatment of both bacterial (category II-NIH) and non bacterial prostatitis (category III-NIH). However, antibiotics need to be associated with other therapies focused on reducing symptoms and providing a better quality of life. In the present study we sought to test the effectiveness of antibiotics and the medical device Proxelan suppositories taken together.
METHODS:
Starting in January 2011, we conducted a randomized controlled trial involving 60 subjects with bacterial and non bacterial chronic prostatitis, who were divided into two groups. Subjects allocated in group A received only antibiotics for 28 days; subjects in group B received antibiotics + Proxelan, for 28 days as well. Before randomization all subjects underwent Meares-Stamey test, IPSS and NIH-CPSI questionnairs. All of those were repeated 60 and 120 days after randomization. Microbiological and clinical efficacy were compared using specific statistical analyses.
RESULTS:
Data were obtained from 29 subjects allocated in group A and 31 in group B. Minor side effects were observed which did not cause study interruption in any case. Of the total population, 68,3% resulted positive to the Meares-Stamey test at study start. Proxelan was not better than antibiotics alone under a microbiological point of view (OR)=0.9; (IR) 0.3-2.8; P=0.46. According to the answers provided at the NIH-CPSI questionnaire, subjects in the group B obtained a better score compared to group A, either after 2 months (OR:2.8; 95%IC 1.2-4.1; P=0.017) and after 4 months (OR:1.67; 95%IC 0.9-2.9; P=0.04). With regards to the IPSS questionnaire, 2 months after treatment start, subjects in the group A had a probability of having urinary symptoms 2 times higher compared to subjects in group B (OR:1.9; 95%IC 1.0-3.5; P=0.028). Although Proxelan seems to improve IPSS also after 4 months, the difference does not reach the level of statistical significance.
CONCLUSION:
Compared to antibiotics alone, the combination of antibiotics and Proxelan improve both symptoms associated to chronic prostatitis and urinary symptoms, however microbiological results are not different. Future studies may be required to confirm our results and to explain the mechanism of action of Proxelan
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
