Impact of Kidney Transplantation on Male Sexual Function: Results from a Ten-Year Retrospective Study
No full textBackground: The effects of kidney transplantation on male sexual function are controversial. Aim: To evaluate the impact of kidney transplantation on erectile and ejaculatory function and to assess a possible correlation between some selected characteristics of patients and their erectile and ejaculatory function after renal transplantation. Methods: An observational retrospective analysis was conducted on male patients who had undergone kidney transplantation from January 2009 to April 2019. A prospectively maintained database was used to collect all data. Patients were evaluated before kidney transplant and 6 and 12 months after kidney transplant. Male patients undergoing renal transplantation for any cause who were sexually active with a stable partner were included in the study. Outcomes: The main outcome measures included the International Index of Erectile Function (IIEF-15) and the 4-item version of Male Sexual Health Quality–Ejaculation Disorders (MSHQ-EjD Short Form) questionnaires. The first 3 questions of the MSHQ-EjD Short Form were used to assess the ejaculatory function, whereas the fourth question was used to evaluate the ejaculation bother. Results: A total of 95 patients were eligible in the study. The evaluation of sexual function was available in 56 patients (58.9%). Mean IIEF-15 significantly decreased at 6 months (P <.001) remaining unchanged at 12 months (P =.228). Mean MSHQ-EjD Short Form (1–3) significantly decreased at 6-month follow-up (P <.001) and at 12-month follow-up (P =.024). Mean MSHQ-EjD Short Form (4) was significantly increased compared with the baseline at both 6 and 12 months (P <.05). IIEF-15 was significantly related to the MSHQ-EjD Short Form at 6-month and 12-month follow-up (P <.001). Age, diabetes, hypertension, smoking, pretransplantation testosterone, time for transplantation, baseline IIEF-15, and baseline MSHQ-EjD Short Form (1–3) were significantly associated (P <.05) with both IIEF-15 and the MSHQ-EjD Short Form (1–3) at 6-month and 12-month follow-up after kidney transplantation. Clinical Implications: Improvement of knowledge regarding the effects of kidney transplantation on sexual function and about the patient characteristics related to sexual health after transplantation. Strength & Limitations: This is the first article that analyzes in depth the ejaculatory function in patients who had undergone kidney transplantation assessing ejaculation with a validated questionnaire. The main limitation is the retrospective design of the study. Conclusion: Kidney transplantation appears to have a negative impact on sexual health, significantly worsening both erectile and ejaculatory functions. Age, diabetes, hypertension, smoking, pretransplantation testosterone levels, time for transplantation, as well as erectile and ejaculatory function before transplant were significantly related to erectile and ejaculatory functions after renal transplantation.

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
Giordano Bruno, la magia e i limiti della ragione
No full textIl saggio analizza l'estensione del concetto di ragione nelle opere di Bruno. Il filosofo ipotizza che le potenzialità della mente, se ben alimentate da un metodo efficace, sono in grado di comprendere i misteri più riposti dei fenomeni naturali. Una volta apprese tutte le cognizioni necessarie, il filosofo-mago può mettere in atto adeguate strategie per attivare i processi naturali. Vi sono però alcuni aspetti della natura che restano insondabili anche alle menti più agili
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
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
