Tension-free vaginal tape versus transobturator tape as surgery for stress urinary incontinence: results of a multicentre randomised trial
No full textObjectives: This prospective, multicentre, randomised study compared the safety and success rate of tension-free vaginal tape (TVT) and transobturator tape (TOT) in treatment of female stress urinary incontinence.
Methods: Of 148 women, 73 were randomised to TVT and 75 to TOT. Preoperative workups included case history, clinical examination, Urogenital Distress Inventory and Impact Incontinence Quality of life questionnaires, 1-h pad test, pelvic ultrasound, and urodynamics. Intra- and postoperative complications were the primary end point; subjective and objective changes in SUI, and postoperative voiding dysfunctions were secondary end points. Patients were classified into two main categories: dry (no leakage during clinical and/or stress test and/or reported by patients) versus wet. Patients who referred being wet were separated into "improved" or "failure" on subjective analysis. Other outcome variables were quality of life questionnaires and VAS scale. Clinical checkups were conducted at 3, 6, 12 mo, and then annually.
Results: Both techniques are safe and no significant differences emerged in intra- and postoperative complications. At a mean follow-up of 31 mo, the overall objective cure (dry) was 71.4% for TVT and 77.3% for TOT (p = ns). When one considered "dry" plus "wet but improved," these values increased to 90% and 90.6%, respectively (p = ns). Median satisfaction rate was 9 (range: 1-10) for both procedures. Postoperative storage symptoms are a controversial issue; they persisted in 44% of patients in TVT group versus 24% in TOT group (p < 0.053).
Conclusions: TOT appears as safe and effective as TVT in surgery for female SUI, with minimal complications at mean follow-up of 31 mo

Hydronephrosis as a Late Complication of ProACT Implantation
Full text linkA n 83-year-old male was referred to the urology clinic because of acute kidney failure and perineal pain and urinary urgency. The patient was treated in 2009 with implantation of an adjustable continence therapy device (ProACT, Uromedica), because of stress urinary incontinence (SUI) after radical prostatectomy (RP). The procedure was performed with transrectal ultrasound (TRUS) guidance under local anesthesia. At the admission, the patient reported perineal and left flank pain. Serum creatinine level was 1.45 mg/dL. All other blood and urine test results were within range. Computed Tomography (CT) imaging revealed left hydronephrosis due to compression of the distal tract of the left ureter by the left side balloon of the device that migrated in the retropubic space, 3 cm above the original position.
What would you do next? (A) Perform a left nephrostomy; (B) Positioning a left ureteral stent; (C) Deflate, remove, and eventually reimplant the device; (D) Deflate the balloon without removing the device. What to do next? (C) Deflate, remove, and eventually reimplant the device. Implanting a ProACT is a safe and efficacious treatment for SUI after RP. The adjustable continencetherapy has high rate of migration as long-term complication.4 The first line treatment after the dislocation of the device causing complications (hydronephrosis, erosion, infections) is the explantation since the procedure is brief and minimally invasive. The patient underwent explantation of the device, performed with TRUS guidance under local anesthesia through two small perineal incisions. Two days later the patient was dismissed after the normalization of the serum creatinine level (0.79 mg/dL) and resolution of hydronephrosis and pain. No complication occurred, except for the recurrence of urinary incontinence (use of 3 pads/die). Patients can be reimplanted or treated with a more invasive treatment option. In our case, the patient decided not to be reimplanted with a new device. Serum creatinine level at 3, 6, and 12 months after the procedure was in range and the abdominal ultrasound tests showed no recurrence of hydronephrosis
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
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
