Secular trends and geographical variations in sex ratio at birth
Numerous studies have established the presence of secular trends and geographical variations in sex ratio at birth, albeit with mixed and often contradictory results. In addition, a multitude of environmental, social, economic, demographic and other factors has been proposed to influence the sex ratio at birth, thus complicating the interpretation of both secular trends and geographical variations. In this paper, the current state of knowledge on these issues is presented and critically assessed. (Source: Early Human Development)

Ionizing radiation and the human gender proportion at birth—A concise review of the literature and complementary analyses of historical and recent data
It has long been known that ionizing radiation causes genetic mutations and that nuclear bomb testing, nuclear accidents, and the regular and incidental emissions of nuclear facilities enhance environmental radioactivity. For this reason, the carcinogenic and genetic impact of ionizing radiation has been an escalating issue for environmental health and human health studies in the past decades. The Windscale fire (1957) and the Chernobyl accident (1986) caused alterations to the human birth sex ratio at national levels across Europe, and childhood cancer and childhood leukemia are consistently elevated near nuclear power pl...

Temporal and regional trends in the secondary sex ratio: The Nordic experience
The sex ratio (SR) at birth, also known as the secondary sex ratio, is defined as the number of males per 100 females and approximates 106. According to the literature, the SR shows notable heterogeneity and attempts have been made to identify factors influencing it, but comparisons demand large data sets. Attempts to identify associations between SRs and stillbirth rates (SBRs) have yielded inconsistent results. A common pattern observed in different countries is that during the first half of the twentieth century, the SR showed increasing trends, but during the second half, the trend decreased.

Cellular and humoral coagulation profiles and occurrence of IVH in VLBW and ELWB infants
Intraventricular hemorrhage (IVH) is a major complication in preterm neonates with significant long-term morbidity and an increased mortality rate. The role of the immature coagulation system in the pathogenesis of IVH in these infants is still under debate. The aim of this study was to provide reference values for coagulation studies within the first 24h of life, and to relate these findings to the incidence of IVH. (Source: Early Human Development)

Influence of the delivery modus on subpopulations and replication of lymphocytes in mothers and newborns
Several studies reported that the mode of delivery may induce changes to the immune system. Our hypothesis was that the delivery mode may influence mainly the naive T cell subpopulation. (Source: Early Human Development)
