Total thyroidectomy vs. lobectomy in differentiated thyroid cancer: is there a reasonable size cut-off for decision? A narrative review
No full textObjective: To analyze all the most recent guidelines/consensus as well as papers regarding the relationship between size of tumor, type of surgery, and prognosis, and to try to produce a critical synthesis for real practice. Background: Differentiated thyroid cancer (DTC) is characterized by a wide range of biological behavior. The type of intervention can range from lobectomy (LT) to total thyroidectomy (TT), with tumor size being a point of discussion in choosing the treatment. Methods: We carried out a search on PubMed, EMBASE, and Cochrane Library, looking at all the guidelines and consensus regarding DTC, as well as examining original articles, inserting as our research keys “total thyroidectomy vs. lobectomy in differentiated thyroid cancer” and “hemithyroidectomy in thyroid cancer”. The guidelines and consensus published over the last 5 years were 6 in total: ATA Guidelines, Italian Consensus of Six Italian Societies, United Kingdom National Multidisciplinary Guidelines, ESMO Clinical Practice Guidelines, a Practical Guidance of a Multidisciplinary Panel of Experts, and The Revised Clinical Practise Guidelines on the Management of Thyroid Tumours by the Japanese Association of Endocrine Surgeons. There were 13 papers cited in the guidelines, and we found another 5 original articles, all of which were retrospective studies. Conclusions: The type of initial surgical intervention must of course consider tumor size, but must also take into account all the risk factors, which is paramount in deciding the type of treatment. LT can have some advantages, and can represent an option that can be offered to patients. However, even in the absence of any special risk factors, a review of the literature suggests to us that patients should be informed that LT for tumors of a size between 2 and 4 cm can be associated with an increased risk of LR as well as with a possible reduced OS

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
