Salvation Gastric Bypass as Conversion from Failed, Open Banded Vertical Gastroplasty
No full textIntroduction: Vertical-banded gastroplasty used to be one of the most performed
bariatric procedures, but it fallen out of interest due to other emerging
procedures and non-satisfactory long-term results. Options for revision include
conversion to sleeve gastrectomy, a Roux-en-Y gastric bypass
(RYGB) or VBG reversal via gastrogastrostomy. Objectives: To evaluate
the role of laparoscopic RYGBP in the treatment of a previous, failed open
VBG. Methods: we present the video of a laparoscopic conversion from
previous open, adjustable banded vertical gastroplasty. Patient was operated
in other center in 1997 at a BMI of 55.3 kg/m2 and arrived a minimumof 30
kg/m2. In 2017 she presented for weight regain and reflux disease (BMI 41
kg/m2), requesting further attention. Intraoperative difficulties, adhesiolisys,
band removal, unexpected situations are presented. Results: Conversion to
laparoscopic RYGBP was safe and efficient, with no need for open surgery
conversion, and further weight loss recorded. Postoperative prolonged respiratory
problems registered, successfully treated conservatively. An important
improvement of the patients’ symptoms and satisfaction was achieved 6
months postoperatively, with suspension of medical therapy, at a BMI of 35
kg/m2. Conclusions: Conversion of open VBG to RYGB is feasible and safe
and can be performed with an acceptable complication rates, especially in
experienced bariatric centers. It gives excellentweight loss results and relief of
outlet obstruction
Gastric Bypass as Conversion from Abandoned Bariatric Procedures: Gastric Plication, Banding or Pacemaker, Toga or Banded Vertical Gastroplasty. A Video Remix
No full textIntroduction: recently, increased numbers of revision bariatric procedures
are reported worldwide, especially due to insufficient
weight loss or weight regain. Some of former bariatric procedures
are currently abandoned or anecdotally used due to long-term
failure and increased incidence of revision surgeries needed.
Objectives: To evaluate the role of laparoscopic gastric bypass LGBP in
the treatment of failure of previous, abandoned bariatric procedures.
Methods: A video remix of laparoscopic conversion from gastric
banding, gastric plication, gastric pacemaker, TOGA or banded
vertical gastroplasty is presented. Patients operated between 1997
and 2010 with different bariatric procedures were converted for
weight regain, comorbidities recurrence, unsatisfactory results.
Intraoperative difficulties, adhesiolisys, different prosthesis removal,
unexpected situations are briefly presented.
Results: no conversion and no mortality were recorded.
Conversion to LGBP was efficient and safe in all revision procedures,
with further weight loss recorded. An important improvement
of the patients’ symptoms and satisfaction was achieved 6
months postoperatively, with suspension of medical therapy, maintained
one year after intervention.Conclusions: conversion in GBP is actually the best option of
treatment in case of weight regain after abandoned, former bariatric
procedures
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
