Effectiveness of MF59-adjuvanted subunit influenza vaccine in preventing hospitalisations for cardiovascular disease, cerebrovascular disease and pne…
2007
Annual circulation of influenza virus coincides with a peak in cardiovascular and pneumonia mortality/morbidity. This study aimed to determine the effectiveness of MF59-adjuvanted subunit influenza vaccine in preventing hospitalisation due to acute coronary syndrome (ACS), cerebrovascular accident (CVA) and pneumonia in the elderly. Three case-control studies were performed during the 2004-2005 influenza season in three health districts in Valencia, Spain (total elderly [>64 years of age] population: n=105,454). Controls were patients admitted for an acute surgical process or trauma within 10 days of case admission. In total, 159 patients were hospitalised for ACS, 148 for CVA and 242 for p…
Prognostic differences between routine invasive and conservative strategies for the management of high-risk, non-ST segment acute coronary syndromes:…
2007
Abstract Background The optimal revascularization strategy for non-ST elevation acute coronary syndromes (NSTE-ACS) remains controversial, especially in a real world context. The objective of this work was to assess differences at 1 year in all-cause mortality and the composite endpoint of mortality or acute myocardial infarction (MI) between two management strategies for NSTE-ACS: a conservative strategy (CS) versus a routine invasive strategy (RIS). Methods Of 799 consecutive patients admitted to our institution, 369 were treated with CS (from January 2001 to October 2002); 430 patients admitted with the same diagnosis were treated with RIS (from November 2002 to November 2004). A propens…
Gender Imbalance across Subfields in Economics: When Does It Start?
2021
We investigate the marked gender imbalance across subfields in economics and connect it with the relative scarcity of female students enrolling in economics. First, tracking authorship in the Ameri...
Rotational CARS thermometry at high temperature (1800 K) and high pressure (0.1-1.55 MPa)
2007
International audience; Dual-broadband rotational CARS (DB-RCARS) thermometry has been investigated at high temperature and high pressure. Single-shot measurements were performed at 1800 K, in air and nitrogen at pressures up to 1.55 MPa and in oxygen at pressures up to 0.5 MPa. For all conditions, the resonant signal contribution to the spectra clearly dominated over the non-resonant one, implying the high potential for DB-RCARS for temperature and concentration measurements also at the high temperatures and pressures used in the present investigation. The relative standard deviation was generally similar to 2% for single-shot data at pressures from 0.5 to 1.55 MPa. At the investigated tem…
¿Cómo se define el liderazgo en la defensa europea? Un análisis fsQCA
2017
The paper addresses the issue of national leadership in the politics of European defence, in order to determine the relative value of different factors in the exercise of leadership, and the reasons why some countries are more willing than others to contribute to the development of the EU’s Common Security and Defence Policy. The article starts by discussing the main contributions of the (neo)realist and constructivist approaches to European leadership on defence. It then highlights the process of development of EU defence policy and its setbacks. Leadership factors that characterize this development process are identified and employed to construct a fsQCA analysis, which assesses the leade…
Meridional gradients of light absorbing carbon over northern Europe
2008
In situ measurements have been made in the upper troposphere of the properties of particles containing light absorbing carbon (LAC). These measurements, made in late November 2006 over northern Europe, show that the average LAC mass concentration varies between 1 and 5 ng m−3 over a latitude range 50° to 70°N, with maxima at 50° and 66°. The relative fraction of all particles larger than 0.1 µm that contain LAC decreases at higher latitudes. The derived extinction coefficient, which also increases with latitude, reaches a maximum of 1.4 Mm−1 at 66°. The air mass histories associated with the LAC were evaluated with back trajectory analysis using wind field analysis from the European Center …
Risk of mortality among children, adolescents, and adults with autism spectrum disorder or attention deficit hyperactivity disorder and their first-d…
2017
BACKGROUND: Autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) are childhood onset neurodevelopmental disorders that may persist into adulthood. ASD and ADHD tend to run in families and may have a significant negative impact on the health and longevity of those with the disorder and their relatives. The aim of this study will be to analyze the risk of mortality among children, adolescents, and adults with ASD or ADHD and their first-degree relatives. METHODS/DESIGN: We will conduct a systematic review and meta-analysis of observational studies. Searches of PubMed/MEDLINE, EMBASE, PsycINFO, SCOPUS, and ISI Web of Science will be used to identify epidemiologica…
Sensing properties of ZnO nanostructured layers
2017
Nanostructured ZnO layers have been deposited onto SiO 2 /Si substrates by spray pyrolysis, with previously patterned interdigitated gold electrodes. We have then measured the capacitive and resistive response against ambient parameters such as relative humidity and illumination.
Aspirin use and breast cancer risk: a meta-analysis and meta-regression of observational studies from 2001 to 2005
2007
Purpose To examine the recent epidemiological studies on aspirin use and breast cancer risk published from 2001 to 2005 within a meta-analysis, to investigate reasons for heterogeneity between the individual studies and to analyse a dose-response-relationship considering frequency and duration of use. Methods We systematically searched for cohort-studies and case-control-studies from 2001–2005, which evaluated the association between aspirin and breast cancer risk. We calculated a pooled estimate for the relative risk (RR) and investigated reasons for heterogeneity between the individual studies and analysed a dose-response-relationship using random effects mixed models. Results We identifi…
