Cardiorenal syndromes
No full textPurpose of review The purpose of the present review is to identify the mechanisms involved in the syndrome related to combined heart-kidney dysfunction. Recent findings The bidirectionality of the syndrome and the various time frames involved in the different clinical pictures have induced to generate a new definition of the cardiorenal syndrome, focusing on five specific subtypes (acute cardiorenal syndrome, type 1; chronic cardiorenal syndrome, type 2; acute renocardiac syndrome, type 3; chronic renocardiac syndrome, type 4; and secondary cardiorenal syndrome, type 5). Summary The new definition allows to characterize the various clinical scenarios and to identify patients with different subtypes in which the primary disorder and the sequelae are clearly described. Biomarkers for early diagnosis of heart and kidney dysfunction may further contribute to a clearer definition of the disorder. The new classification will allow to test diagnostic tools and prevention strategies as well as therapeutic measures that in the past might not have been applied properly due to the lack of a consistent classification of the syndrome
Digital strategies for the valorisation of archival heritage
Full text link20th century pre-digital architectural archives are a current topic of interest for scholars involved in historical studies as well as those studying conservation, valorisation and communication. These vast archival heritages could be enhanced by the methodologies, techniques and tools offered by the digital revolution. The present proposal demonstrates this potential through the application of structure from motion techniques to a physical scale model that represents the Turin Horse Racing designed by Carlo Mollino. Moreover, the paper presents a comparison of different software, methodologies and modelling tools and suggests a design for virtual and on-site communication strategies. These strategies fuel new interrelations of knowledge and ideas, through which an archive can become a place of convergence between the real and the virtual
Contrast induced acute kidney injury in interventional cardiology: An update and key guidance for clinicians
Full text linkContrast-induced acute kidney injury (CI-AKI) is a serious complication that can affect outcome and prognosis of patients undergoing percutaneous diagnostic and interventional procedures in catheterization laboratories. There have been advancements in case definition and epidemiology. Additionally strategies have emerged that are positioned to have impact in the catheterization laboratory for patients undergoing cardiovascular procedures. The aim of this review is to provide the state-of-the-art of diagnosis, prevention and management of CI-AKI in interventional cardiology
Cardio-renal syndromes: a systematic approach for consensus definition and classification
No full textThe "Cardio-Renal Syndrome" (CRS) is a disorder of the heart and kidneys whereby acute or chronic dysfunction in one organ may induce acute or chronic dysfunction of the other. The general definition has been expanded to five subtypes reflecting the primacy of organ dysfunction and the time-frame of the syndrome: CRS type I: acute worsening of heart function (AHF-ACS) leading to kidney injury and/or dysfunction. CRS type II: chronic abnormalities in heart function (CHF-CHD) leading to kidney injury or dysfunction. CRS type III: acute worsening of kidney function (AKI) leading to heart injury and/or dysfunction. CRS type IV: chronic kidney disease (CKD) leading to heart injury, disease and/or dysfunction. CRS type V: systemic conditions leading to simultaneous injury and/or dysfunction of heart and kidney. Different pathophysiological mechanisms are involved in the combined dysfunction of heart and kidney in these five types of the syndrome
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
