The implantable cardioverter-defibrillator: Implications for the recognition of civil disability and proposal for medical-legal update [Il defibrillatore automatico impiantabile: Implicazioni per il riconoscimento di invalidità civile e proposta di aggiornamento medico-legale]
No full textBackground. Indications to the implantable cardioverter-defibrillator (ICD) have been expanded in the last decade, including patients suffering from heart disease with or without functional disorders. Accordingly, the increasing number of patients with ICD is posing relevant legal implications. Currently, the Medical Committee that evaluates the legal criteria for disability is employing guidelines referring only to pacemaker devices and not to ICD. The aim of this study was to propose new indications for patients with ICD to replace the current criteria. Methods. The study included 219 patients (83%male, mean age 63 years) with ICD who were administered an anonymous questionnaire to evaluate the presence of any disability. Most patients were suffering from ischemic or non-ischemic dilated heart disease (41% and 34%, respectively). Single- and dual-chamber ICD (72%) were more frequently implanted compared to biventricular ICD (28%). Results. A higher percentage of disability was found in older patients (69±14 years) with ischemic heart disease (61%) and single- or dual-chamber ICD before ICD implantation. Conversely, a lower percentage of disability was found in younger patients (53±15 years), active workers (44%), without ischemic or non-ischemic dilated heart disease (36%), and with a lower number of biventricular ICD (22%) after ICD implantation. Conclusions. Overall, these data show that disability is currently recognized because of the presence of ICD rather than the underlying heart disease. We propose, therefore, new criteria that include the impact of the underlying heart disease for a better evaluation of disability in patients with ICD

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
Exploring the effects of static magnetic fields for the enhanced valorization of sewage sludge by anaerobic digestion
No full textAnaerobic digestion (AD) is an interesting and sustainable option to handle sewage sludge (SS), as it generates a methane-rich biogas and a digestate with potential fertilizing properties. Several strategies have been proposed to enhance AD performances and the valorization of SS. Among these, the application of a static magnetic field (SMF) has been poorly evaluated and recently gained attention. This work investigated the effect of low-intensity SMF (20-50 mT) on methane production from AD of SS, comparing it to the effect deriving from the application of a high-intensity SMF (1.5 T). Magnetic pretreatment at 20 mT was particularly effective, as it increased biomethane production up to 12.9% compared to the control test. On the contrary, 1.5 T was ineffective in terms of cumulative methane production, as it resulted in a 20.9% decrease. These outcomes suggest that SMF intensity is inversely related to biomethane generation and that further investigations are worthy to understand the mechanisms underlying AD enhancement by SMF applicatio
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
