Postural alterations in breast cancer survivors: proposal of the PABS evaluation protocol based on a systematic review
No full textINTRODUCTION: The constant improvement of the diagnostic process and the crescent efficacy of treatment options for Breast Cancer have led to an increase in the survival rate of patients. Thereby, it has become fundamental for Breast Care Units to deal with short-, medium-, and long-term sequelae of the disease and its treatment. Among these, changes in posture seem to have a crucial role. This review aims to collect and summarize the current knowledge on postural disorders in Breast Cancer Survivors, focusing on evaluation methods and rehabilitation protocols.EVIDENCE ACQUISITION: A systematic research was conducted on PubMed, Scopus and World of Science databases, considering all the studies published up to 2021. Case reports, case series, cross-sectional, retrospective and prospective studies were included. Narrative and Sys-tematic reviews were excluded.EVIDENCE SYNTHESIS: After applying the eligibility criteria and bibliographic expansion, 55 articles were selected. Forty-four studies fo-cused on the analysis and the quantification of postural abnormalities, showing a huge variability in population characteristics, valuative methods and outcome measures. Most of them are cross-sectional studies. Rehabilitation treatments have been considered in only 12 studies: all the reha-bilitative treatments proved to be effective but, the heterogeneity among the evaluation methods has made a comparison impossible. Hence, we designed a complete evaluation protocol for the assessment of postural abnormalities in Breast Cancer Survivors. Our protocol has been drawn following the structure of International Classification of Functioning, Disability and Health.CONCLUSIONS: Our review pointed out the crescent interest of the current Literature on analysis and treatment of postural alterations in breast cancer survivors. Since the extreme variety of outcome measures made it impossible to give a clear indication for evaluation and treatment of this disorder, we designed a complete evaluation protocol for the assessment of postural abnormalities in breast cancer survivors, with the goal of guiding the design of new clinical trials on these subjects.(Cite this article as: Doro E, Azzollini V, Ghilli M, Roncella M, Chisari C.

Phyllodes tumors of the breast

Fine needle aspiration cytopathology of phyllodes tumor. Differential diagnosis with fibroadenoma
No full textThe differential diagnosis of benign or borderline phyllodes tumors of the breast in fine needle aspiration biopsy smears was studied. Smears from five histologically proven cases and 20 proven cases of fibroadenoma were evaluated with regard to their cytologic features. The findings indicate that the presence of a high cellularity of stromal fragments (including bipolar naked nuclei), clusters of hyperplastic ductal cells and giant cells and the absence of apocrine metaplasia may suggest a diagnosis of phyllodes tumor, as opposed to fibroadenoma. The borderline phyllodes tumor showed a sarcomatous atypia and/or small intranuclear cytoplasmic invaginations in some cells. The differential diagnosis of this tumor with malignant phyllodes tumor and plasma-cell mastitis is also discussed
Correlation between 5-year survival of T1-T2N0 breast cancer and some pathological parameters.
No full textAbstract
In order to more clearly define the factors influencing prognosis, 113 cases of T1-T2N0 breast cancers, all operated on by means of radical mastectomy, were reviewed. The following pathologic parameters were analyzed in relation to 5 years survival: histological type, nuclear grading, vascular embolization, size and border of the tumour, and sinus histiocytosis, diffuse cortical hyperplasia and germinal center hyperplasia of axillary nodes. We observed a close correlation between the presence of sinus histiocytosis and prognosis, as many authors have reported. Diffuse cortical hyperplasia stands out from our data as the most unfavourable prognostic factor.

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
