Defining the Inframammary Fold by Liposuction: An Essential Tool in Aesthetic Shaping of the Reconstructed Breast. Technique and Long-term Results in a Series of Patients
Full text linkAbstract
Background A good inframammary fold (IMF) definition
and position is essential to achieve a satisfactory and natural
result in breast surgery. This structure can be damaged,
especially during mastectomies. Multiple methods are
reported in the literature to restore IMF or improve its
definition. In this study, we present the results achieved in a
series of patients treated with subdermal liposuction.
Methods We report on all our patients who underwent IMF
liposuction between January 2016 and June 2020. Subdermal
liposuction was performed with a blunt 3 mm
cannula along the new IMF to promote skin retraction and
adherence between skin and fascia. Results were evaluated
subjectively by the patients and objectively by 8 individuals
not involved with the treatment.
Results We performed IMF liposuction in 88 breasts (69
patients), aged 21–74 (mean 52) years for 82 implant-based
reconstructions, 2 tuberous breasts, and 4 contralateral
breast augmentations. Mean follow-up was 28 months
(6–64). Subjective results: the overall result evaluated with
the VAS scale reached 86.6/100. All the 22 patients
interviewed judged as well defined the new inframammary
fold. Objective results: in 83% of cases the definition of the
inframammary fold was judged as good or excellent, while
symmetry with contralateral IMF, natural appearance, and
overall aesthetic outcome were judged as good.
Conclusion Based on our long-term satisfactory results,
we recommend the technique of subdermal liposuction to
improve the definition of IMF in breast reconstruction after
mastectomy and other breast procedures. It is effective,
easy to perform, minimally invasive, and durable
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
"Solving vessel caliber mismatch in microvascular anastomosis: A comprehensive review, novel techniques, and a surgical guide for optimal outcomes"
Full text linkCaliber mismatch in microvascular anastomosis can significantly increase procedural difficulty and elevate the
risk of thrombosis. A comprehensive literature search in PubMed, Scopus, Web of Science, and Google Scholar
was conducted to identify articles addressing surgical techniques for overcoming caliber mismatch in microvascular anastomosis. Various techniques described in the literature were found: modifications of end-to-end
anastomosis, the use of end-to-side anastomosis, the application of vessel grafts and the use of vessel couplers.
In this review, we critically analyze these techniques and introduce additional technical variations. We discuss
the options and express our preferred choice of methods based on specific clinical scenarios: if an alternative
vessel (either new or isolated further away) is not found, the severity of the mismatch guides the choice. When
less then 1/3 our choice is for vessel dilation and oblique cut of the smaller vessel end (if necessary with the
adjunct of a titanium small Ligaclip in an oblique fashion to avoid a cul-de-sac). If caliber mismatch is around or
over 1/3, we would prefer an end to side anastomosis
