Special Use of Intraoperative Endoscopy in Sleeve Gastrectomy: A Case Report
No full textSleeve gastrectomy is the most frequently performed operation for the treatment of morbid obesity. Even though sleeve gastrectomy is now widely standardized, it may still benefit from the use of certain devices and procedures such as intraoperative endoscopy. The use of an endoscope offers numerous advantages that can considerably reduce the morbidity and mortality of patients who undergo laparoscopic sleeve gastrectomy. This paper describes our experience with a case in which the information obtained by endoscopy allowed us to perform a real-time assessment of the location of two large gastric polyps to control the staple-line
Self-Retaining Retractor Widox® for Thyroid Surgeries: Technical Note
No full textDuring a thyroidectomy, perfect exposure of the vascular nerve structures, parathyroid gland, trachea, larynx, esophagus, and lymphnodes is crucial to facilitate the surgeon in the meticulous dissection. WIDOX® (MOSS Spa, Lesa, Italy) is an atraumatic self-retaining thyroidectomy retractor specifically designed for thyroid surgeries with an octagonal shape and six retractors (Fig. 1). It is a sterile, single-use device which keeps the surgical wound and the neck muscles retracted allowing the proper exposure of the operatory field. The device substitutes the manual retractors held by the surgeon's assistants. In our institute, we started using the self-retaining retractor WIDOX® from May 2015 for a total of 50 patients. From our preliminary experience, the self-retaining retractor WIDOX® is simple and practical and can be adapted to each patient. The use of energy-based devices and the neuromonitoring is not prevented by the presence of this retractor
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
Transoral Endoscopic Thyroidectomy Vestibular Approach (TOETVA): From A to Z
No full text: We depict the transoral endoscopic thyroidectomy vestibular approach (TOETVA). Patient selection criteria are (1) ultrasonographically (US) estimated thyroid diameter no larger than 10cm, (2) US estimated gland volume ≥45mL, (3) nodule size ≥5mm, (4) a benign tumor, such as a thyroid cyst, single-nodular goiter, or multinodular goiter, (5) follicular neoplasm, and (6) papillary microcarcinoma without evidence of metastasis. TOETVA is carried out through a three-port technique placed at the oral vestibule, one 10mm port for 30° endoscope and two additional 5mm ports for dissecting and coagulating instruments. CO2 insufflation pressure is set at 6mmHg. An anterior cervical subplatysmal space is created from the oral vestibule down to the sternal notch, laterally to the sternocleidomastoid muscles bilaterally. Thyroidectomy is done fully endoscopically using conventional endoscopic instruments. Intraoperative neuromonitoring is used for identification and dissecting and monitoring both the superior and inferior laryngeal nerves
