Mesh in prolapse surgery
No full textProlapse repair with synthetic mesh has become an area of debate in the last few years. The rationale for mesh use in prolapse surgery, the surgical outcomes and its complication profile will help us to understand the concerns and controversies regarding it. The lifetime risk of undergoing surgery for prolapse by age 80 is around 11 % and reoperation rate is quoted around 29 % [1]. The recurrence risk and the need for reoperation in nearly one-third to one-fourth of patients with prolapse surgeries means there is a need for more robust techniques in prolapse repair. Our understanding of pelvic floor anatomy changed dramatically since the description of "levels of pelvic organ support" by John DeLancey [2]. In order to fully understand the dynamics of prolapse surgery, both native tissue and mesh repair, it is important to have a brief overview of the functional anatomy of the pelvic floor, which has been covered adequately in an earlier chapter of this textbook. Many of the treatments for pelvic organ prolapse (POP) offered today have been developed bearing in mind this renewed understanding of pelvic floor anatomy
Management of sling surgery complications
No full textThe management of urodynamically proven stress urinary incontinence underwent a paradigm shift with the focus changing from bladder neck suspension to support of the mid-urethra in the last two decades. This has resulted in the replacement of Burch colposuspension and pubo-vaginal slings to synthetic mid-urethral slings as the primary surgical option in women with stress urinary incontinence (SUI). The introduction of synthetic mid-urethral slings has resulted in good objective and subjective cure rates but can be associated with complications that pose a challenge to the treating surgeon. Surgical treatment for SUI has rapidly evolved, and the initially introduced mid-urethral sling, retropubic tension-free vaginal tape (TVT), is accepted worldwide as a standard treatment for women suffering from SUI. However, slings have been associated with a few early and delayed complications which may result in varying degrees of morbidity. Serious complications such as bowel injury, major vascular injury, and even death have been reported with mid-urethral sling procedures.
Sling complications are related to the sling type, surgical technique and time elapsed postsurgery. Though there are numerous devices available in the market, three different types of mid-urethral slings are commonly described in current practice, namely-retropubic slings (TVT, GYNECARE TM; AMS TM, RetroArc), transobturator slings (AMS TM, Monarc; TVT-O, GYNECARE TM ) and single-incision mini-slings (AMS TM, MiniArc). The rationale for choice of sling has been discussed elsewhere in this book and the surgical technique varies with the type of sling chosen which in turn is intricately related to type of complications seen with slings. This chapter deals with the management of synthetic mid-urethral sling complications in the intra-operative and postoperative period
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
