BACKGROUND Mental health disorders impact approximately one in four US adults. While their causes are likely multifactorial, prior research has linked the risk of certain mental health disorders to prenatal and early childhood environmental exposures, motivating a spatial analysis to determine whether risk varies by birth location. METHODS We investigated the spatial associations between resi...

BACKGROUND AND AIM Literature evaluating association between neonatal morbidity and immigrant status presents contradictory results. Poorer compliance with prenatal care and greater social risk factors among immigrants could play roles as major confounding variables, thus explaining contradictions. We examined whether prenatal care and social risk factors are confounding variables in the relati...

background: we sought to determine the association between factors that affected clinical pregnancy and live birth rates in patients who underwent in vitro fertilization (ivf) and received intracytoplasmic sperm injection (icsi) and/or laser assisted hatching (lah), or neither. materials and methods: in this retrospective cohort study, the records of women who underwent ivf with or without icsi...

In pig production, parturition progress is a key event for sow's reproductive performance, evaluated by piglet survival and piglets' performance. The aim of this study was to investigate the impact of feeding a high-fibre (HF) diet during gestation on parturition progress and reproductive performance of sows. Forty-two primiparous sows (Large-White × Landrace crossbred) were fed during gestatio...

BACKGROUND Rates of preterm birth are rising worldwide. Studies from the United States and Latin America suggest that much of this rise relates to increased rates of medically indicated preterm birth. In contrast, European and Australian data suggest that increases in spontaneous preterm labour also play a role. We aimed, in a population-based database of 5 million people, to determine the temp...

In a house-to-house survey in Kilifi District, Kenya, mothers of 2556 liveborn children were interviewed about neonatal mortality, especially from neonatal tetanus (NNT). The crude birth rate was 60.5 per 1000 population, the neonatal mortality rate 21.1 and the NNT mortality rate 3.1 per 1000 livebirths. The neonatal and NNT mortality rates were higher in boys than in girls. Neonatal tetanus w...

BACKGROUND Israeli Jews of European origin have high incidence rates of all cancers, and many of them were exposed to severe famine and stress during World War II. We assessed cancer incidence in Israeli Jewish survivors of World War II. METHODS Cancer rates were compared in a cohort of 315 544 Israeli Jews who were born in Europe and immigrated to Israel before or during World War II (nonexp...

Received 10 June 2008 Accepted 15 October 2008 Published Online First 13 November 2008 ABSTRACT Background: Thirteen studies investigating the association between asthma during pregnancy and perinatal mortality reported generally no increased risk. Most of these studies should be interpreted with caution because they were limited in terms of statistical power. A study was therefore undertaken t...

OBJECTIVES This report presents preliminary data for 2000 on births in the United States. U.S. data on births are shown by age, race, and Hispanic origin of mother. Data on marital status, prenatal care, cesarean delivery, and low birthweight are also presented. METHODS Data in this report are based on more than 96 percent of births for 2000. The records are weighted to independent control co...
