[Autologous transfusion technique application table].
No full textThe authors make a survey on the reasons leading to the application of different methods of autologous transfusion. They underline, incidentally, the important role played by the issues encountered in dealing with Jehovah's Witnesses as well as the discovery and spread of new transfusion transmitted diseases like AIDS and hepatitis C. They explain their experience, from which they have produced a Best Autologous Transfusion Technique Application Table (Scheda di Applicazione Ottimale delle Metodiche di Autotrasfusione, SAOMA), specific for every type, of operation, through the analysis of many parameters (surgeon, anaesthetist, transfusionist, general conditions of the patients, type of surgical operation). Moreover the authors evaluate advantages and disadvantages of the different autologous transfusion methods, including their cost efficiency aspects, and how they can be combined depending on the type of surgical operation. As a conclusion they attribute great importance to SAOMA to minimize homologous blood transfusion risks, even though at times the clinical aspect is made to prevail over the economic one
Predeposit and intraoperative blood salvage in elective abdominal aortic aneurysm repair
No full textWe evaluated the efficiency and costs-effectiveness of blood predonation and intraoperative salvage in elective abdominal aortic aneurysm surgery. Between January 1992 and January 1994, 66 patients (59 male and 7 female, aged 69.9 ± 0.8 years) who underwent elective surgical repair of an AAA were selected for the study. Thirty-six (54.5%) patients (Group 1) intra- and/or postoperatively received homologous blood whereas 30 (45.5%) patients (Group 2) received autologous blood predonation and intraoperative blood aspiration and reinfusion. The two groups were similar for demographic data, aneurysmal diameter and associated diseases and/or risk factors (p = NS). Operative mortality was comparable between the two groups (p = NS). The mean intraoperative blood loss was 803.4 ± 104.5 ml in group 1 and 812.8 ± 44.8 ml in group 2 (p = NS). Group 2 patients received intra- or postoperatively a mean of 0.8 ± 0.2 units of homologous blood (p < 0.001). Aneurysmal diameter did not influence the transfusion requirement between the two groups (p = NS). The cost per unit of homologous banked blood was significantly higher (p < 0.01). Cumulative costs of the procedures did not show statistical differences between the two groups (p = NS). Aortic surgery is the ideal target for predonation and intraoperative blood salvage
In tema di Autotrasfusione: salasso preoperatorio immediato ed emodiluizione moderata con Destrano 70.000
No full textDopo alcuni cenni storici relativi alla metodica vengono ricordati i vari tipi di tecniche in uso per realizzare l'autotrasfusione.
La tecnica adottata dagli autori e realizzata in vari tipi di chirurgia, prevede un salasso preoperatorio immediato con emodiluizione moderata ottenuta con destrano 70.000; il sangue prelevato è stato sempre trasfuso durante o al termine degli intervent

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
