Twenty-year trends in the prevalence of Down syndrome and other trisomies in Europe : impact of maternal age and prenatal screening
2013
This study examines trends and geographical differences in total and live birth prevalence of trisomies 21, 18 and 13 with regard to increasing maternal age and prenatal diagnosis in Europe. Twenty-one population-based EUROCAT registries covering 6.1 million births between 1990 and 2009 participated. Trisomy cases included live births, fetal deaths from 20 weeks gestational age and terminations of pregnancy for fetal anomaly. We present correction to 20 weeks gestational age (ie, correcting early terminations for the probability of fetal survival to 20 weeks) to allow for artefactual screening-related differences in total prevalence. Poisson regression was used. The proportion of births in …

Classification of hospital pathways in the management of cancer: application to lung cancer in the region of burgundy.

Methods : We used the national medico-administrative DRG-type database, which gathers together all hospital stays. By using this database…

Los estudios sobre el virus de la polio comenzaron en Valencia en 1959 de la mano del microbiólogo Vicente Sanchis-Bayarri Vaillant. Tras su formación en virología en la Universidad de Rochester y en el Instituto Pasteur, puso en marcha un laboratorio de cultivos celulares en la Facultad de Medicina de Valencia, en donde desarrolló una técnica diagnóstica nueva para el virus de la polio. Por otra parte, se llevaron a cabo estudios epidemiológicos antes y después de la campaña de vacunación de 1963, que demostraron la eficacia de la vacuna oral de Sabin y su inocuidad.// Els estudis sobre el virus de la pòlio van començar a València en 1959 de la mà del microbiòleg Vicente Sanchis-Bayarri Va…
