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.

Monitoraggio del nodulo tiroideo benigno in accordo con la classe di rischio ecografica
Full text linkL’ecografia è il principale strumento diagnostico nell’ambito della patologia nodulare tiroidea. Negli ultimi anni si sono susseguite diverse linee guida finalizzate a standardizzare la descrizione ecografica e a modulare la gestione del nodulo tiroideo sulla base delle caratteristiche ecografiche. Tra le più utilizzate a livello internazionale vi sono quelle dell’American Association of Clinical Endocrinologists/American College of Endocrinology/Associazione Medici Endocrinologi (AACE/ACE/AME) [1], le linee guida 2015 dell’American Thyroid Association (ATA) [2], le linee guida della European Thyroid Association (ETA) (European Thyroid Imaging Reporting and Data System) [3] e l’American College of Radiology (ACR) TIRADS [4].
L’obiettivo primario di queste linee guida è quello di identificare, sulla base delle caratteristiche ecografiche, i noduli a maggior rischio di malignità da sottoporre ad agoaspirato (FNAC) e di ridurre il numero di agoaspirazioni tiroidee non necessarie, senza tuttavia aumentare il numero di mancate diagnosi di cancro tiroideo. La definizione del rischio ecografico del nodulo è inoltre utilizzata per modulare il follow-up a breve e a lungo termine dei noduli tiroidei citologicamente o ecograficamente benigni [4]
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
