Multikinase and highly selective kinase inhibitors in the neoadjuvant treatment of patients with thyroid cancer
No full textMultikinase inhibitors (MKIs) and highly selective tyrosine kinase inhibitors (HS-TKIs) positively impact the progression-free survival (PFS) of locally advanced and metastatic thyroid cancer cases. Moreover, disease-specific survival (DSS) and overall survival (OS) improvements were observed in some instances, suggesting a general benefit in disease control. In advanced and metastatic thyroid cancers, other conventional treatments are often ineffective when surgery cannot be performed due to the extension of the disease and/or the invasion of vital neck structures (such as the larynx, trachea, esophagus, recurrent laryngeal nerve, and carotid artery). In these cases, systemic treatments with MKIs and HS-TKIs have recently been evaluated for their potential to block tumor growth and reduce tumor size to make surgery possible or improve the control of metastatic disease. The study aimed to evaluate the performance of these systemic drugs in the neoadjuvant treatment of thyroid cancer patients, focusing on their efficacy according to the different histology
Stato nutrizionale e risposta al trattamento con inibitori tirosino-chinasici nel carcinoma tiroideo avanzato
Full text linkL’utilizzo di inibitori tirosino-chinasici (TKI) rappresenta un’importante opzione terapeutica nel trattamento del carcinoma tiroideo metastatico. Il trattamento con tali farmaci è frequentemente associato alla comparsa di eventi avversi che possono compromettere uno stato nutrizionale già precario, tipico di questi pazienti, peggiorandone quindi anche la prognosi. Diversi studi hanno valutato l’impatto dello stato nutrizionale e della presenza di sarcopenia sulla risposta al trattamento e sulla sopravvivenza dei pazienti oncologici. Tali parametri sembrano correlare con la prognosi e la sopravvivenza nei pazienti oncologici
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
Radioiodine therapy in the different stages of differentiated thyroid cancer
No full textDifferentiated thyroid cancer is the most frequent type of thyroid cancer with an increasing incidence in the last decades. The initial management is represented by surgical treatment followed by radioactive iodine therapy that includes remnant ablation, adjuvant treatment or treatment of metastatic disease. Radioactive iodine treatment is performed only in selected cases based on the risk of recurrence and mortality during follow up, according to American Joint Committee on Cancer Union for international Cancer Control Tumor, Node, Metastasis (AJCC/TNM) staging system and the 2015 American Thyroid Association (ATA) risk stratification system. This article will review the key factors to consider when planning radioactive iodine therapy in differentiated thyroid cancer patients after surgery and during follow up.(c) 2022 Elsevier Ltd.
