No full textRationale In patients with >50% carotid artery stenosis (as measured by North American Symptomatic Carotid Endarterectomy Trial (NASCET) criteria) suffering a transient ischemic attack or a minor ipsilateral stroke, carotid endarterectomy exerts maximum benefits, when performed within the first 15 days from the initial ischemic symptom. It is also known that the probability of a major stroke spikes within the first few days after a transient ischemic attack/minor stroke and then flattens out in the following days and weeks. It could be hypothesized that urgent carotid endarterectomy has greater benefit than delayed procedure. Aims Demonstrate that urgent carotid endarterectomy is more effective than delayed interventions. Design Centers employing neurolgist/stroke physicians and vascular surgeons will enroll TIA or minor stroke patients with >50 % carotid artery stenosis (Nascet criteria), randomized in two groups: 1) urgent carotid endarterectomy (within 48 hours) and 2) delayed carotid endarterectomy (operated between 48 hours and 15 days after onset of symptoms) Risk factors will be evaluated at enrollment. TIA will be classified by ABCD2 scoring system, and minor stroke by National Institutes of Health Stroke Scale (NIHSS) scores. The study will last 90 days per patient, starting from their initial symptom, and the follow-up will be performed by an indipendent neurologist. A total of 456 patients (228 / group) is needed to observe an absolute difference of 10% between groups. Outcomes Primary end-point is reduction in all types of stroke, AMI or death in urgent endarterectomy groupo compared to delayed ones. Secondary end-points are: - Reduction of ipsilateral ischemic stroke in group 1 with respect to Group 2 - Identification of predictive risk factors and - Confirmation of no different rate for hemorragic/ischemiccomplications between groups

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
