Editorial: New Perspectives on Pediatric Acute Leukemia
Full text linkThe scenario of pediatric acute leukemia has changed extremely rapidly over these last decade and the pediatric hematologists are now facing new challenges related to the biology of the disease, the prognostic classifications of patients, and the consequent risk-based targeted approach. Acute lymphoblastic leukemia (ALL) in children has always represented a paradigm of success, and the recent advent of large-scale genomic studies and novel immunotherapy-based approaches have further revolutionized the perspective on this disease. Pediatric acute myeloid leukemia (AML) still suffers from a lower cure rate if compared to ALL, due to a still high incidence of recurrence and of severe and dose-limiting short- and long-term toxicities. Nevertheless, much has been learned about the biology of the disease through studies of specific recurrent genetic lesions and the outcomes for these children are progressively improving thanks to the great collaborative efforts of the main pediatric AML groups worldwide
Gonadal tumors
No full textThis encompassing volume gathers contributions by renowned experts in the field of pediatric urology to offer a systematic and complete review of the field. The book opens with a general section covering the basis of renal function from the fetus to adulthood, diagnostic imaging, anesthesia and infections. In subsequent sections on the kidneys, upper urinary tract, bladder, urethra and genitalia, specific anomalies are described in depth, from embryological, clinical and diagnostic aspects through to surgical treatment options. Detailed attention is devoted to the role of new technologies such as endoscopic and robotic surgery, but without disregarding the classical principles of pediatric urologic surgery. Urogenital tumors are fully covered and the book closes with a large chapter on renal transplantation. Numerous black and white and color illustrations will assist the reader in better understanding the various anomalies and the surgical procedures
Factors influencing the implementation of the woman-centred care model for pregnant women in a hospital setting: an integrative review
No full textBackground: The term “Woman-Centred Care” focuses on the individual needs, aspirations and expectations of the woman herself rather than the needs of the healthcare system or professionals. The principles on which this model of care is based, are the control, choice, and continuity of care for women. Objective: The objective of this review would like to explore and summarise the evidence currently available on the factors which influence the implementation of the care model for pregnant women in a hospital setting. Methods: An integrative review was conducted using the method of Whittemore and Knafl and the PICOT search strategy. The Medline, PubMed and CINAHL databases were examined to identify primary studies that, between 2013 and July 2024, investigated factors influencing the implementation of women-centred care models in hospital settings. The inclusion/exclusion process and reporting followed the PRISMA 2020 guidelines. The qualitỳ of the studies was assessed according to the criteria of the Mixed Method appraisal tool. Findings: 411 studies were eligible and 16 of those included. A total of 16 records were included. Four themes and four sub-themes influencing the implementation of Woman-Centred Care were identified: the perspective of the midwives; the care model; communication and collaboration (relationships with colleagues; relationship with women and empowerment) and, resources and support (organisation and stakeholders; management). Discussion: The implementation of the “Woman-Centred Care" model is strongly influenced by organizational policies and midwives' awareness of their role as guarantors of "natural" childbirth. Conclusion: The lack of a shared understanding of what Woman-Centred Care actually means can contribute to the confusion and definition with which it is proposed
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
