BACKGROUND The effects of in utero exposure to atypical antipsychotics on infant birth weight are unknown. AIMS To determine whether atypical and typical antipsychotics differ in their effects on birth weight after maternal exposure during pregnancy. METHOD Prospective data on gestational age and birth weight collected by the National Teratology Information Service for infants exposed to ty...

Many phenols are known to mimic or antagonize hormonal activities and may adversely affect fetal growth. A study of 567 pregnant women was conducted to investigate the relationship between prenatal phenol exposure and birth outcomes, including birth weight, length, and gestational age. We measured the concentrations of bisphenol A, benzophenone-3, 4-n-octylphenol and 4-n-nonylphenol in maternal...

BACKGROUND Prior studies of prenatal exposure to tetrachloroethylene (PCE) have shown mixed results regarding its effect on birth weight and gestational age. OBJECTIVES In this retrospective cohort study we examined whether PCE contamination of public drinking-water supplies in Massachusetts influenced the birth weight and gestational duration of children whose mothers were exposed before the...

BACKGROUND Previous studies have suggested a possible link between exposure to influenza in utero and bipolar disorder in adulthood. Using data from a prospective birth cohort, we aimed to test for an association between exposure to gestational influenza and the experience of hypomania assessed in early adulthood. METHODS We used data on 2957 participants from the Avon Longitudinal Study of P...

Determining fetal drug exposure (except at the time of birth) is not possible for both logistical and ethical reasons. Therefore, we developed a novel maternal-fetal physiologically based pharmacokinetic (m-f-PBPK) model to predict fetal exposure to drugs and populated this model with gestational age-dependent changes in maternal-fetal physiology. Then, we used this m-f-PBPK to: 1) perform a se...

OBJECTIVE To review systematically maternal antenatal cocaine exposure and adverse perinatal outcomes. STUDY DESIGN Medline, Embase, CINAHL and secondary references in relevant studies were searched. English language studies of antenatal cocaine exposure and pregnancy outcomes published from 1966 to July 2009 were included. Metaanalyses were performed using the random effects model. RESULTS...

BACKGROUND Cigarette smoke exposure during prenatal and early postnatal periods increases the incidence of a variety of abnormal behaviors later in life. The purpose of this study was to identify the possible critical period of susceptibility to cigarette smoke exposure and evaluate the possibe effects of cigarette smoke during early life on brain-derived neurotrophic factor/neurotrophic tyrosi...

INTRODUCTION There is a need for additional information on the fetal risks and relative safety of the pandemic H1N1 monovalent or trivalent influenza (pH1N1)-containing vaccines in women exposed during pregnancy. METHODS To assess risks and relative safety of the pH1N1-containing vaccines, we conducted a prospective cohort study of pH1N1-vaccine-exposed and unexposed comparison women residing...

Tumorigenesis is a complex process involving genetic, epigenetic, and metabolic alterations. Gestational arsenic exposure has been shown to increase hepatic tumors in adult male offspring of C3H mice, which spontaneously develop hepatic tumors often harboring activating Ha-ras mutation. We explored tumor-promoting changes by gestational arsenic exposure with a focus on Ha-ras mutation and gene ...
