Urodynamics Before Surgery for Stress Urinary Incontinence: The Urodynamic Examination Is Still One of the Best Friends of the Surgeon and of Patients with Stress Urinary Incontinence
No full textIn the large majority of patients with stress urinary incontinence, urodynamics could provide new information, in comparison to simple clinical examination, and change subsequent management in a relevant percentage of cases
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

No full textIn a bladder overactivity model of cystitis induced by intravesical infusion of acetic acid (a.a.), several parameters of spinal nerve stimulation (SNS) were optimized using continuous infusion cystometry. The optimal stimulation was further characterized through measurements of urodynamic function using single-fill cystometry
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
Conservative management of adult neurogenic lower urinary tract dysfunction
No full textNeurogenic lower urinary tract dysfunction (NLTUD) is commonly encountered in neuro-rehabilitation settings and is caused by a variety of pathologies. The management of spinal cord injury (SCI) has been the model of reference for the approach to NLTUD due to many other diseases of the central and peripheral nervous system. The decline in renal-related mortality in SCI patients after the introduction of clean intermittent catheterization in association with pharmacological treatment (antimuscarinics in particular), and the algorithms proposed since 1998 by the International Consultations on Incontinence underline the need of early assessment and treatment of urinary incontinence and/or urinary retention in neuropathic patients. The aim of this brief review was to provide useful guidelines for physiatrists and neurologists in order to early and correctly manage all types of NLUTDS, well knowing that a correct management is useful not only for avoiding renal failure, but also for improving urinary continence, voiding dysfunction, and the quality of life of patients. The rehabilitation treatment consists of conservative, noninvasive or minimally invasive techniques, in the context of which intermittent catheterization and pharmacotherapy represent the more important modalities. After a brief description of specific interventions, the management of NLTUD in stroke, Parkinson's disease, multiple sclerosis and SCI patients is underlined, emphasizing the importance of a dedicated team in rehabilitation units
Pro-Act substitution for mechanical rupture of the periurethral balloon: Step-by-step surgical education video
No full textStress urinary incontinence (SUI) is a feared complication after radical prostatectomy because it impacts on the quality of life and determines a high rate of emotional distress (Nash et al., 2018 [1]). When the conservative approach in terms of behavioral, physical (pelvic-floor rehabilitation) and pharmacological treatments fails, a surgical management is usually recommended to treat the post-prostatectomy stress urinary incontinence. The Adjustable Continence Therapy prosthesis (Pro-ACT) is a postoperatively adjustable device that aims to achieve optimal outlet resistance by progressively increasing the volume of the periurethral balloons. Furthermore, in case of mechanical rupture or balloon leakage it can be easily substituted (removed and reimplanted) in centers with experience (Finazzi Agra et al., 2019 [2]). In this video we present the clinical case of a male patient who had undergone PRO-ACT implantation about 10 years ago. Due to the right balloon leakage, its substitution was indicated and performed under ultrasound guidance (Gregori et al., 2010 [3]). The aim of the current manuscript is to provide a description of the surgical technique. The related video shows the technique as a set of simple steps that make the surgical procedure safe and reproducible
