Correzione dell'insufficienza polmonare con homograft criopreservato: ottima soluzione ad un problema post-chirurgico non raro
No full textAlthough the results of surgical repair for congenital pulmonary stenosis are generally good, some patients develop progressive symptoms related to pulmonary regurgitation and right ventricular dilation. Pulmonary homograft implantation may have a beneficial effect on these symptoms, due to a reduction in the volume overload of the right ventricle and hemodynamic improvement. We describe our experience of one patient with severe pulmonary regurgitation following pulmonary valvotomy performed with the Brock technique during childhood because of pulmonary valve stenosis. The patient was admitted to our Institution because of dyspnea on exertion (NYHA functional class II-III) and paroxysmal episodes of supraventricular arrhythmias. Echocardiography showed severe pulmonary regurgitation, an important right ventricular dilation associated with severe tricuspid insufficiency and a patent foramen ovale without any significant shunts. Surgical repair was performed through a median sternotomy with cardiopulmonary bypass and moderate hypothermia. The right ventricular infundibulum was opened and a cryopreserved pulmonary homograft was implanted with continuous sutures. De Vega annuloplasty was performed on the tricuspid valve and the patent foramen ovale was closed with a running suture. Postoperative course was uneventful and the patient was discharged on the seventh postoperative day. Three months after surgery the patient is asymptomatic and echocardiographic evaluation shows no evidence of pulmonary or tricuspid regurgitation, a decrease in right ventricular dilation and a significant improvement in biventricular systolic and diastolic function. In conclusion, pulmonary regurgitation after surgical valvotomy can be treated with the implantation of a cryopreserved pulmonary homograft with satisfactory results. It would appear advisable to perform surgical repair of concomitant right heart anomalies, such as secondary tricuspid insufficiency, to obtain both a decrease in right ventricular overload and a regression of its preoperative dilation

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
