The effects of postmastectomy adjuvant radiotherapy on immediate two-stage prosthetic breast reconstruction. A systematic review
No full textSir: We read with great interest the Viewpoint1 published by Maione et al. in the May issue of the Journal entitled “The Effects of Postmastectomy Adjuvant Radiotherapy on Immediate Two-Stage Prosthetic Breast Reconstruction: A Systematic Review.” The first author (D.R.) knows the authors personally, and theyhave contributed a lot in the field of regenerative surgery, and their report highlights again how important this topic is
Review of quality of patient information regarding Botox® cosmetic on the internet
No full textOne of the world's most popular and widely used cosmetic treatments is Botox®.1, 2 It is injected into facial muscles in order to temporarily improve the appearance of moderate to severe frown lines and crow's feet lines in adults. The popularity of Botox® treatments is manifested in the large number of patients searching for information on Internet for indications, costs, effects and good practitioners, prior to consulting a health professional
Breast reconstruction using the Profunda Artery Perforator (PAP) flap: technical refinements and evolution, outcomes and patient satisfaction based on 116 consecutive flaps
Full text linkIntroduction: When a deep inferior epigastric artery flap is not suitable, the profunda artery perforator (PAP) flap can be a good alternative for autologous breast reconstruction. Popularity of the PAP flap is expanding, but it is still only slowly being adopted worldwide. We report our experience with 116 consecutive PAP flaps showing refinements and evolution of the technique towards improvement in outcomes and patients’ satisfaction. Methods: We prospectively collected data from consecutive PAP flap breast reconstructions performed from 2016 to 2019. Patients’ demographics, pre-, intra-, postoperative data, and revision procedures were analyzed. The BREAST-Q and a specific questionnaire investigating outcomes at the donor site were completed preoperatively and 12 months postoperatively. Results: One-hundred and sixteen PAP flaps were performed in 86 patients, 64 unilateral and 22 bilateral breast reconstructions. Mean body mass index was 24.72 kg/m 2 (range 18.9–29.2) and mean flap weight was 251.30 g (range 152–455 g). Complications included donor site hematoma (1.7%), seroma (2.6%), fat necrosis (1.7%), and wound dehiscence (2.6%). No arterial/venous thrombosis nor flap losses were recorded. Patients reported high satisfaction in all BREAST-Q domains, with mean postoperative scores being higher than preoperative ones, suggesting a positive effect in quality of life and satisfaction. Scores were significant in the satisfaction with breast domain (p = 0.0016). Conclusions: Breast reconstruction with PAP flap yields a high success, low complications, and excellent cosmetic outcomes in the breast and donor sites. It improves patients’ satisfaction and quality of life; hence, it can be considered an excellent option for autologous breast reconstruction
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
