    Understanding the Heterogeneity of Perinatal Depression

    Most studies evaluating the prevalence of perinatal depression are cross-sectional, meaning that depressive symptoms are measured at a single point in time.  Less information is available regarding the trajectory of perinatal depression.  In obstetric populations, it seems that there are women with briefer episodes of milder postpartum depressive symptoms, while others have more persistent and debilitating depressive symptoms after childbirth.  Other women experience depression during pregnancy.  Several studies suggest that there is considerable heterogeneity among women who experience depressive symptoms during pregnancy and the postpartum period.

    Good News: New Studies Show No Association Between Antidepressants and Risk of Autism

    Two recent epidemiologic studies have demonstrated an association between prenatal exposure to selective serotonin reuptake inhibitor antidepressants (SSRIs) with autism spectrum disorders (ASD; Croen et al 2011, Rai et al, 2013).  One important imitation of these two studies is that parental psychiatric disorder in itself is associated with an increased risk of ASD in the offspring, and these studies could not distinguish between the effects of drug exposure and the consequences of the underlying maternal psychiatric illness.  Two new studies shed light on the association between prenatal antidepressant exposure and risk of autism spectrum disorder in the offspring.

    Folic Acid Supplements Before and After Conception: Prevention of Autism

    In a recent editorial in The Annals of Internal Medicine entitled “Enough Is Enough: Stop Wasting Money on Vitamin and Mineral Supplements,” authors make a case that multivitamins are not a good value (Dec 17, 2013 issue).  This editorial was based on new research that demonstrated that there was no association between multivitamin use and rates of mortality, cognitive decline and recurrent cardiovascular events in three different studies.  The assertion that multivitamins are not worth the money was widely reported in the media.

    Cognitive Development in Children Exposed to Levetiracetam (Keppra)

    An increasing number of reproductive age women now take newer anticonvulsants for the treatment of mood and anxiety disorders; however, information regarding the reproductive safety of these medications is limited.  A recent study has evaluated the cognitive and language development of children born to women with epilepsy exposed in utero to levetiracetam (LEV, Keppra) or sodium valproate (VPA, Depakote), as compared to control children born to women without epilepsy not taking medication during pregnancy.

    Do SSRIs Increase the Risk of Postpartum Hemorrhage? Maybe, But Not By Much

    Selective serotonin reuptake inhibitor (SSRI) antidepressants may affect platelet aggregation and thus may increase the risk of bleeding.  Several studies have sought to determine if exposure to SSRI antidepressants in late pregnancy is associated with an increased risk of postpartum hemorrhage.
