Autoría: desde el crédito a la responsabilidad. Reflexiones de la Red de Editores / Authorship: from credit to accountability. Reflections from the Editors´ Network / Autoria: do crédito à responsabilidade. Reflexões da Rede de Editores

Resumen: La Red de Editores de la Sociedad Europea de Cardiología (ESC, por su sigla en inglés) constituye un foro dinámico dedicado a discusiones editoriales y respalda las recomendaciones del Comité Internacional de Editores de Revistas Médicas (ICMJE, por su sigla en inglés) destinadas a mejorar la calidad científica de las revistas biomédicas. La paternidad literaria confiere crédito, además de importantes recompensas académicas. Recientemente, sin embargo, el ICMJE ha destacado que la autoría también exige que los autores sean responsables y se hagan cargo de lo que publican. Estas cuestiones ahora están cubiertas por el nuevo (cuarto) criterio para la autoría. Los autores deben aceptar hacerse responsables de lo que escriben y garantizar un adecuado enfoque de las cuestiones concernientes a la precisión e integridad de todo el trabajo. Esta revisión analiza las implicancias de este cambio de paradigma en los requisitos de autoría con el objetivo de aumentar la conciencia sobre las buenas prácticas científicas y editoriales.

Summary: The Editors´ Network of the European Society of Cardiology provides a dynamic forum for editorial discussions and endorses the recommendations of the International Committee of Medical Journal Editors to improve the scientific quality of biomedical journals. Authorship confers credit and important academic rewards. Recently, however, the International Committee of Medical Journal Editors emphasized that authorship also requires responsibility and accountability. These issues are now covered by the new (fourth) criterion for authorship. Authors should agree to be accountable and ensure that questions regarding the accuracy and integrity of the entire work will be appropriately addressed. This review discusses the implications of this paradigm shift on authorship requirements with the aim of increasing awareness on good scientific and editorial practices.

Antithrombotic therapy use and clinical outcomes following thrombo-embolic events in patients with atrial fibrillation: insights from ARISTOTLE

METHOD AND RESULTS:Thrombo-embolic events were defined as stroke (ischaemic or unknown cause) or systemic embolism (SE). Clinical outcomes were estimated using the Kaplan­Meier method. All-cause mortality and International Society on Thrombosis and Haemostasis (ISTH) major bleeding after events were analysed using a Cox proportional hazards model with time-dependent covariates. Of 18 201 patients in ARISTOTLE, 365 experienced a thrombo-embolic event [337 strokes (ischaemic or unknown cause), 28 SE]; 46 (12.6%) of which were fatal. In the 30 days before and after a thrombo-embolic event, 11% and 37% of patients, respectively, were not taking an oral anticoagulant. During follow-up (median 1.8 years), 22 patients (7.1%/year) had a recurrent stroke, 97 (30.1%/year) died, and 10 (6.7%/year) had major bleeding. Compared with patients without a thrombo-embolic event, the short- and long-term adjusted hazards of death in patients with a thrombo-embolic event were high [30 days: HR 3.5, 95% CI 2.5­4.8; both P< 0.001]. The adjusted hazards of major bleeding were also high short-term (HR 10.37, 95% CI 3.87­27.78; P< 0.001) but not long-term (HR 1.7, 95% CI: 0.77­3.88; P= 0.18). CONCLUSIONS: Thrombo-embolic events were rare but associated with high short- and long-term morbidity and mortality. Substantial numbers of patients are not receiving oral anticoagulant therapy before and, despite this risk, after a first thrombo-embolic event.

Data Sharing: A New Editorial Initiative of the International Committee of Medical Journal Editors. Implications for the Editors' Network / Compartir los datos de los estudios: Una nueva iniciativa editorial del Comité Internacional de Editores de Revistas Médicas. Implicaciones para la red europea de editores cardiovasculares

Abstract: The International Committee of Medical Journal Editors (ICMJE) provides recommendations to improve the editorial standards and scientific quality of biomedical journals. These recommendations range from uniform technical requirements to more complex and elusive editorial issues including ethical aspects of the scientific process. Recently, registration of clinical trials, conflicts of interest disclosure, and new criteria for authorship - emphasizing the importance of responsibility and accountability -, have been proposed. Last year, a new editorial initiative to foster sharing of clinical trial data was launched. This review discusses this novel initiative with the aim of increasing awareness among readers, investigators, authors and editors belonging to the Editors' Network of the European Society of Cardiology.

Resumen: El Comite internacional de editores de revistas medicas (CIERM) propone recomendaciones para mejorar los standares editoriales y la calidad científica de las revistas biomédicas. Estas recomendaciones abarcan desde requerimeintos ténicos uniformados a temas editoriales mas complejos y evasivos, como los aspectos bioéticos relacionados con el proceso científico. Recientemente se han propuesto algunas iniciativas editoriales, como el registro de los ensayos clinicos, la declaración de los conflictos de interés y los nuevos criterios para autoría (que destacan la responsabilidad de los autores sobre el estudio). El año pasado se presentó una nueva iniciativa editorial para resaltar la importancia de compartir los datos generados en los estudios clinicos. En este artículo se discute esta nueva iniciativa editorial, con la idea de difundir su conocimiento entre los lectores, investigadores, autores y editores de la red de editores de revistas cardiovasculares nacionales de la Sociedad Europea de Cardiología.

Resumo O Comitê Internacional de Editores de Revistas Médicas (ICMJE) fornece recomendações para aprimorar o padrão editorial e a qualidade científica das revistas biomédicas. Tais recomendações variam desde requisitos técnicos de uniformização até assuntos editoriais mais complexos e elusivos, como os aspectos éticos do processo científico. Recentemente, foram propostos registro de ensaios clínicos, divulgação de conflitos de interesse e novos critérios de autoria, enfatizando a importância da responsabilidade e da responsabilização. No último ano, lançou-se uma nova iniciativa editorial para fomentar o compartilhamento dos dados de ensaios clínicos. Esta revisão discute essa nova iniciativa visando a aumentar a conscientização de leitores, investigadores, autores e editores filiados à Rede de Editores da Sociedade Europeia de Cardiologia.

Políticas de conflictos de intereses y requisitos para su declaración en las revistas cardiovasculares nacionales de la Sociedad Europea de Cardiología / Conflict of interest policies and disclosure requirements among european society of cardiology national cardiovascular journals

Las revistas biomédicas utilizan la declaración de posibles conflictos de intereses para garantizar la credibilidad y la transparencia del proceso científico. Sin embargo, las revistas no abordan la declaración de conflictos de intereses de manera sistemática ni uniforme. Recientes esfuerzos editoriales conjuntos han abierto el camino a la aplicación de herramientas uniformes para la declaración de conflictos de intereses. En este artículo se presenta una visión integral sobre cuestiones clásicas relacionadas con los conflictos de intereses desde un punto de vista editorial. Además, a partir de los datos de un estudio transversal basado en el empleo de un cuestionario estandarizado, se comentan nuevas apreciaciones sobre las políticas y los actuales procedimientos editoriales relativos a los conflictos de intereses en las diversas revistas cardiovasculares nacionales de la Sociedad Europea de Cardiología.

Disclosure of potential conflicts of interest is used by biomedical journals to guarantee credibility and transparency of the scientific process. Conflict of interest disclosure, however, is not systematically nor consistently dealt with by journals. Recent joint editorial efforts paved the way towards the implementation of uniform vehicles for conflicts of interest disclosure. This paper provides a comprehensive editorial perspective on classical conflict of interest-related issues. New insights into current conflicts of interest policies and practices among European Society of Cardiology national cardiovascular journals, as derived from a cross-sectional survey using a standardized questionnaire, are discussed.

Prospective evaluation of clinical outcomes after acute ST-elevation myocardial infarction in patients who are ineligible for reperfusion therapy: Preliminary results from the TETAMI registry nd randomized trial

BACKGROUND: Treatment with lytics or primary percutaneous coronary interventions (PCI) reduces the mortality rate of patients with ST-elevation myocardial infarction (STEMI) presenting within 12 hours. Patients presenting >12 hours are generally considered to be ineligible for reperfusion therapy, and there are currently no specific treatment recommendations for this subgroup.Methods- All patients with STEMI 12 hours. Apart from 34 of these patients who had a stuttering infarction and were referred for reperfusion, the remaining patients did not receive reperfusion therapy.Registry patients who received reperfusion therapy, compared with TETAMI randomized patients (all of whom received antithrombotic therapy) and registry patients who did not receive reperfusion, were younger (61 years versus 63 years and 67 years), were more likely to be male (78% versus 73% and 63%), and had persistent ST-segment elevation as opposed to LBBB or Q waves...

The safety and efficacy of subcutaneous enoxaparin versus intravenous unfractionated heparin and tirofiban versus placebo in the treatment of acute ST-segment elevation myocardial infarction Patients ineligible for reperfusion (TETAMI): a randomized trial

The aims of the Safety and Efficacy of Subcutaneous Enoxaparin Versus Intravenous Unfractionated Heparin and Tirofiban Versus Placebo in the Treatment of Acute ST-Segment Elevation Myocardial Infarction Patients Ineligible for Reperfusion (TETAMI) study were to demonstrate that enoxaparin was superior to unfractionated heparin (UFH) and that tirofiban was better than placebo in patients with acute ST-segment elevation myocardial infarction (STEMI) who do not receive timely reperfusion. BACKGROUND: An optimal treatment strategy has not been identified for the many STEMI patients ineligible for acute reperfusion. METHODS: A total of 1224 patients were enrolled in 91 centers in 14 countries between July 1999 and July 2002. Patients with STEMI ineligible for reperfusion were randomized to enoxaparin, enoxaparin plus tirofiban, UFH, or UFH plus tirofiban. All patients received oral aspirin. The primary efficacy end point was the 30-day combined incidence of death, reinfarction, or recurrent angina; the primary analysis was the comparison of the pooled enoxaparin and UFH groups. REULTS: The incidence of the primary efficacy end point was 15.7% enoxaparin versus 17.3% for UFH (odds ratio 0.89 [95% confidence interval CI = 0.66 to 1.21]) and 16.6% for tirofiban versus 16.4% for placebo (odds ratio 1.02 [95% CI 0.75 to 1.38]). The Thrombolysis In Myocardial Infarction (TIMI) major hemorrhage rate was 1.5% for enoxaparin versus 1.3% for UFH (odds ratio 1.16 [95% CI 0.44 to 3.02]) and 1.8% versus 1% for tirofiban versus Placebo (odds ratio 1.82 ([95% CI 0.67 to 4.95])...
