Psychiatric Symptoms and Proinflammatory Cytokines in Pregnancy
Clinical studies suggest that psychiatric symptoms, particularly depression, anxiety and trauma, may be associated with inflammation, as indexed by proinflammatory cytokines. Such a link may be especially significant in pregnancy, and may shed additional light on the etiology of perinatal mood disorders
The Effects of Trauma History and Prenatal Affective Symptoms on Obstetric Outcomes: Trauma, Anxiety, and Birthweight
Prenatal maternal mood may explain the adverse obstetric outcomes seen in disadvantaged populations yet the effects of trauma history are not well studied. We examined the impact of trauma exposure and mood symptoms on obstetric outcomes in 358 women. Women with antecedent trauma were more likely to have a history of depression χ2(1, N = 358) = 19.2, p =.001; OR = 2.83, 95% CI [1.81, 4.42], were younger at their first pregnancy t(356) = −2.97, p = .003 and had a higher number of previous pregnancies t(356) = 2.77, p = .011 compared to those with no trauma exposure. Women with prenatal anxiety had significantly smaller babies than nonanxious women F(1, 322) = 5.32, p = .024. Trauma history magnified the effects of maternal prenatal mood on birth weight; the moderating effect was limited to those who first experienced a trauma under 18 years of age F(14, 320) = 2.44, p =.005. Childhood trauma exposure increases vulnerability for low birthweight delivery associated with prenatal mood disturbance. Screening pregnant women for trauma history and current mood symptoms is indicated
Does transvaginal ultrasound at 13-15 weeks improve anatomic survey completion rates in obese gravidas?
Obesity increases the difficulty of completing the fetal anatomic survey. This is of added concern in obese gravidas who are at higher risk of congenital fetal anomalies. We hypothesized that incorporation of an early transvaginal assessment could improve the completion rate of the fetal anatomic survey in obese women. We performed a prospective, longitudinal, blinded study of obese gravidas (BMI ≥ 35 kg/m) comparing the use of a single early second trimester transvaginal ultrasound in addition to midtrimester transabdominal ultrasound versus traditional serial midtrimester ultrasound alone for completion of the anatomic survey. Transvaginal ultrasound for anatomy was performed between 13 0/7 and 15 6/7 week followed by midtrimester anatomic ultrasound, with each patient serving as her own control. Structures were marked as optimally or suboptimally viewed after each ultrasound. Sonographers and reviewers were blinded to images from the transvaginal ultrasound. Completion rates and gestational age at completion were compared between groups. Fifty subjects were included. Fetal anatomic survey was completed in 62% using standard midtrimester assessment versus 78% with the addition of early transvaginal assessment ( = .04). The survey was completed at an earlier gestational age utilizing the transvaginal approach (22 0/7 ± 6 3/7) compared to traditional midtrimester transabdominal ultrasound approach (25 2/7 ± 5 3/7) \u3c .0005. Incorporation of an early transvaginal assessment of anatomy in obese women improved the rate of completion and led to earlier gestational age at completion of the fetal anatomic survey. Consideration should be given to including an early transvaginal sonogram as part of routine assessment of women with a BMI ≥ 35

Vitamin B<sub>12</sub> Status in Pregnant Adolescents and Their Infants
Vitamin B12 deficiency has been associated with increased risk of adverse pregnancy outcomes. Few prospective studies have investigated the burden or determinants of vitamin B12 deficiency early in life, particularly among pregnant adolescents and their children. The objectives of this study were to determine the prevalence of vitamin B12 deficiency and to examine associations between maternal and neonatal vitamin B12 status in a cohort study of healthy pregnant adolescents. Serum vitamin B12 and folate concentrations were measured in adolescents at mid-gestation (n = 124; 26.4 ± 3.5 weeks) and delivery (n = 131; 40.0 ± 1.3 weeks), and in neonates at birth using cord blood. Linear regression was used to examine associations between maternal and neonatal vitamin B12 status. Although the prevalence of vitamin B12 deficiency (<148.0 pmol/L; 1.6%) in adolescents was low during pregnancy, 22.6% of adolescents were vitamin B12 insufficient (<221.0 pmol/L; 22.6%) at mid-gestation. Maternal vitamin B12 concentrations significantly decreased from mid-gestation to delivery (p < 0.0001), and 53.4% had insufficient vitamin B12 status at delivery. Maternal vitamin B12 concentrations (p < 0.001) and vitamin B12 deficiency (p = 0.002) at delivery were significantly associated with infant vitamin B12 concentrations in multivariate analyses, adjusting for gestational age, maternal age, parity, smoking status, relationship status, prenatal supplement use, pre-pregnancy body mass index, race, and intake of vitamin B12 and folate. Maternal vitamin B12 concentrations significantly decreased during pregnancy and predicted neonatal vitamin B12 status in a cohort of healthy pregnant adolescents
