Happy New Year! Only a week into 2019, there is no shortage of articles to review and discuss. Over the last week, the article that has received the most press is the one documenting the association between prenatal use of valproic acid and increased risk of ADHD in exposed offspring. This adds to a long list of deleterious effects stemming from prenatal exposure to valproic acid, including high risk of congenital malformations, increased risk of autism, and other neurodevelopmental problems.
Over the last few years, we have also seen an increased number of articles which have attempted to measure the impact of prenatal depression and anxiety on children’s behavior. Kataja and colleagues observe that anxiety an/or depression experienced by the mother early on in the pregnancy may alter how the infant perceives new stimuli and may make children more likely to perceive a given stimulus as threatening.

Prenatal exposure to valproic acid, but not other AEDs, is associated with a small increase in risk of ADHD.

Families in which both mothers and fathers had high levels of depressive symptoms were more likely to exhibit marital negativity, parenting stress, lower levels of parental efficacy, and internalizing and externalizing problems in the children.

Maternal prenatal but not postpartum anxiety symptoms were associated with higher threat bias in infants, and the relationship between maternal anxiety symptoms in early pregnancy and higher threat bias in infants remained significant after controlling for maternal postpartum symptoms. Maternal postpartum anxiety symptoms were associated with higher probability of disengagement from faces to distractors, but the effects varied by child sex.

The overall probability of an infant to visually disengage from faces to distractors was not related to maternal depressive symptoms, but fear bias was heightened in infants whose mothers reported depressive symptoms.

Pregnancy was inversely associated with alcohol use disorder across all analyses (odds ratios, 0.17-0.32). Within individuals, rates of alcohol use disorder were substantially decreased during pregnancy relative to the prepregnancy period (odds ratios, 0.25-0.26), and they remained reduced during postpartum periods (odds ratios, 0.23-0.31).

For women attending a clinical service with relatively high fatigue and psychological distress, postpartum depression and fatigue remain separate but related experiences.

33% of the women who were dissatisfied with their body image suffered from perinatal depression vs. 11.3% of the women who were not dissatisfied (p?<?0.0001). The risk of perinatal depression was 4 times higher in women dissatisfied with their body image (p?<?0.001) if unintended pregnancy and age are taken into account and is 3 times significantly higher in women with higher levels of eating disorder symptoms (p?<?0.001) if unintended pregnancy and age are taken into account.

In a mouse model of postpartum depression, SAGE-516, which is a novel, synthetic allopregnanolone analog similar to brexanolone, reduced depressive=like symptoms and improved maternal care. The researchers hypothesize that SAGE-516 may work by preventing the stress-induced increases in corticosterone that occur during the postpartum period in this animal model.

In this study from the UK, of 206?517 women, 23?623 (11%) had a record of depressive diagnosis or symptoms in the year after delivery and more than one in eight women received antidepressant treatment. 6848 (3%) of women were referred for non-pharmacological treatment. Recording and treatment peaked 6-8 weeks after delivery. A third of the women had at least one record suggestive of depression at any time point prior to delivery and of these one in four received SSRI treatment in the year after delivery.Younger women were most likely to have records of depression and depressive symptoms. (Relative risk for postnatal depression: age 15-19: 1.92 (1.76 to 2.10), age 20-24: 1.49 (1.39 to 1.59) versus age 30-34). The risk of depression, postnatal depression and depressive symptoms increased with increasing social deprivation.

Physical activity (PA) during pregnancy appears to reduce the risk of PPD symptoms; however, there was considerable heterogeneity among the studies with regard to how PA was assessed and how PPD symptoms were identified.

Clusters of PMDD symptoms appear to be stable across multiple menstrual cycles (except of pain and eating behavior). Somatic dysphoria was the cluster most strongly associated with impairment. As the risk of impairment differs between symptom clusters, individual treatment options should be considered and further investigated in research and treatment.
