Pregnancy and birth cohort resources in europe: a large opportunity for aetiological child health research

BACKGROUND During the past 25 years, many pregnancy and birth cohorts have been established. Each cohort provides unique opportunities for examining associations of early-life exposures with child development and health. However, to fully exploit the large amount of available resources and to facilitate cross-cohort collaboration, it is necessary to have accessible information on each cohort and its individual characteristics. The aim of this work was to provide an overview of European pregnancy and birth cohorts registered in a freely accessible database located at http://www.birthcohorts.net. METHODS European pregnancy and birth cohorts initiated in 1980 or later with at least 300 mother-child pairs enrolled during pregnancy or at birth, and with postnatal data, were eligible for inclusion. Eligible cohorts were invited to provide information on the data and biological samples collected, as well as the timing of data collection. RESULTS In total, 70 cohorts were identified. Of these, 56 fulfilled the inclusion criteria encompassing a total of more than 500,000 live-born European children. The cohorts represented 19 countries with the majority of cohorts located in Northern and Western Europe. Some cohorts were general with multiple aims, whilst others focused on specific health or exposure-related research questions. CONCLUSION This work demonstrates a great potential for cross-cohort collaboration addressing important aspects of child health. The web site, http://www.birthcohorts.net, proved to be a useful tool for accessing information on European pregnancy and birth cohorts and their characteristics.

"Beyond Freud and Jung": Sabina Spielrein's Contribution to Child Psychoanalysis and Developmental Psychology

Up to the present day, Sabina Spielrein has been seen as a means to deeper understanding of Freud and Jung and, in particular, the relationship between these two “great men”. This is also the reason why her scholarly achievements after her 1912 essay "Destruction as the Cause of Coming Into Being” are hardly taken into account. This study shows that Spielrein's main research work was in the areas of child analysis and developmental psychology—that is, beyond the work and the persons of Freud and Jung—and that she made numerous significant contributions to the field, so many of them ahead of her time.
