No full textThe European society of cardiology ACCA-EAPCI registry on ST elevation myocardial infarction: A new Registry to evaluate the treatment of STEMI across Europe and the Mediterranean countries is discussed
No full textThe main objective of this study is to describe the demographic, clinical,
and biological characteristics of patients with STEMI admitted to
a representative setting of cardiology centres in ESC-member countries
in Europe.
Other objectives are to assess management patterns and in particular
the current use of reperfusion therapies and to evaluate how recommendations
of most recent STEMI European guidelines regarding reperfusion
therapies and adjunctive pharmacological and non-pharmacological treatments
are adopted in clinical practice and how their application can impact
on patients’ outcomes. Information on the reasons why evidencebased
treatments are not utilized will be collected.
An interesting objective will be to evaluate the organization of
STEMI management across Europe and Mediterranean countries specifically
regarding the diagnostic and admission process and treatment
pathways. The registry will validate the prognostic predictors of inhospital
and 1-year outcomes. In particular, patients with
Cardiopulmonary resuscitation and/or cardiogenic shock, who still
present a high mortality rate despite reperfusion therapy. A 1-year
follow-up will be performed to assess long-term event rate and adherence
to secondary prevention measures
Economic implications of intra-aortic balloon support for myocardial infarction with cardiogenic shock: an analysis from the IABP-SHOCK II-trial
No full textThe Intra-aortic Balloon Pump in Cardiogenic Shock II (IABP-SHOCK II) trial has demonstrated the safety of intra-aortic balloon (IABP) support in patients with acute myocardial infarction (AMI) complicated by cardiogenic shock, but no beneficial effect on mortality. Currently, intra-aortic balloon pumping is still the most widely used support device. However, little is known about the economic implications associated with this device. Data of 600 patients included in the IABP-SHOCK II trial (registered at ClinicalTrials.gov, NCT00491036) with follow-up at 30 days, 6 and 12 months were subjected to an economic analysis. Patients with cardiogenic shock complicating AMI were randomly assigned to IABP additionally to optimal medical therapy (OMT; n = 301) or OMT alone (n = 299) before early revascularization. Costs were calculated from the perspective of a German healthcare payer. Cost-effectiveness and cost-utility analyses were performed using quality-adjusted life years (QALY) and reduction in New York Heart Association (NYHA) and Canadian Cardiac Society (CCS) class as effectiveness measures. There was a statistically significant difference in overall costs between the IABP (33,155 +/- A 14,593 a,not sign) and the control group (32,538 +/- A 14,031 a,not sign, p < 0.00001). This was predominantly attributed to the IABP costs in the IABP (760 +/- A 174 a,not sign) versus control group (64 +/- A 218 a,not sign, p < 0.0001) whilst the intensive care unit costs did not differ between the groups (29,177 +/- A 12,013 a,not sign and 29,401 +/- A 12,063 a,not sign, p = 0.82). There was no significant difference in QALY or NYHA and CCS reduction, respectively (p = n.s.). IABP support is associated with higher healthcare costs as compared to conservative treatment regimens. Clinically, IABP support cannot generally be recommended in AMI complicated by cardiogenic shock in the absence of a mortality benefit. However, economically considering the relatively little contribution to overall costs generated by IABP therapy it may still be considered if clinical scenarios with an IABP-induced benefit may be identified in the future
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
