Key clinical point: A significant and independent association was observed between the serum soluble suppression of tumorigenicity 2 (sST2) and N-terminal probrain natriuretic peptide (NT-proBNP) levels during the second or early-third trimester and the onset of preeclampsia in women with twin pregnancies.

Major finding: Twin pregnancies with vs without preeclampsia were associated with significantly higher maternal serum levels of sST2 and NT-proBNP in the second and early-third trimesters (both P < .001), with a serum sST2 level of ≥30.7 ng/mL (odds ratio [OR] 8.13; P < .001) and NT-proBNP level of ≥282.2 pg/mL (OR 7.20; P < .001) being independently associated with the occurrence of preeclampsia in twin pregnancies.

Study details: Findings are from a longitudinal nested case-control study that included women with dichorionic twin pregnancies from a prospective cohort and compared women with (n = 78) and without (n = 78) preeclampsia.

Key clinical point: Exposure to computed tomography pulmonary angiography (CTPA) in pregnant women with clinically suspected pulmonary embolism (PE) did not lead to neonatal hypothyroidism among newborns.

Major finding: In newborns from pregnant women with suspected PE who underwent CTPA, all reported Guthrie levels were below 15 U/mL, with no newborns with neonatal hypothyroidism (0.0%, 95% CI 0.0%-2.5%).

Study details: The data come from a prospective management outcome study that evaluated 149 pregnant women (including 14 with twin pregnancies) with suspected PE who underwent CTPA.

Key clinical point: Majority of women undergoing medical termination of pregnancy (MTOP) for fetal anomaly at ≥20 weeks’ gestation had successful unassisted deliveries, but a quarter had common or severe morbidities, with the most common morbidities being postpartum hemorrhage and manual removal of retained placental tissue.

Major finding: Overall, 99.0% of women undergoing MTOP for fetal anomaly at ≥20 weeks' gestation had spontaneous vaginal deliveries and 25.5% had a common or severe morbidity, with the most common maternal morbidities being manual removal of retained placental tissue (16.0%) and postpartum hemorrhage (11.1%). Severe maternal morbidity occurred in 1.3% of cases and included amniotic fluid embolism. No maternal deaths were reported.

Key clinical point: The use vs non-use of antihistamines during later stages (20-36 weeks) of pregnancy increased the risk for early-onset preeclampsia in women with allergy, whereas the risk was insignificant with antihistamine use before (<6 months) or during early stages of (<20 weeks) pregnancy.

Major finding: Compared with no antihistamine use, the risk for early-onset preeclampsia (<34 weeks in pregnancy) was high among women with allergy who used antihistamines during late pregnancy (odds ratio [OR] 1.8; 95% CI 1.5-2.2), but was insignificant among those who used antihistamines before or during early pregnancy.

Study details: Findings are from a population-based cohort study including 692,487 pregnancies in women with allergy; 101,287 women used antihistamines either before or during early or late pregnancy.

Disclosures: This study was funded by the University of Bergen. No conflicts of interest were declared.

Key clinical point: Pregnancies complicated by cardiomyopathy are more likely to result in adverse perinatal outcomes, including stillbirth, neonatal mortality, preterm birth, and small-for-gestational age neonates compared to healthy pregnancies or those with no other cardiac diseases.

Major finding: Pregnancies complicated by cardiomyopathy vs healthy pregnancies were more likely to result in stillbirth (odds ratio [OR] 20.82; P < .00001), neonatal mortality (OR 6.75; P < .00001), preterm birth (OR 5.95; P < .00001), and small-for-gestational age neonates (OR 6.74; P < .00001), with outcomes being similar when compared with pregnancies complicated by other forms of cardiac disease.

Study details: Findings are from a systematic review and meta-analysis of 13 observational cohort, case-control, and case-cohort studies including 2,291,024 pregnancies either complicated by cardiomyopathy or other forms of cardiac diseases and those with no cardiac diseases.

Key clinical point: Management of shoulder dystocia with fetal manipulation (FM) increased the risk for obstetric anal sphincter injury (OASI), with FM being associated with an increased risk for OASI and severe neonatal morbidity.

Major finding: Shoulder dystocia managed with vs without FM resulted in significantly higher rates of OASI (21.1% vs 3.8%; odds ratio [OR] 6.72; 95% CI 2.7-15.8) but similar rates of severe neonatal morbidity. FM was associated with the occurrence of OASI (adjusted OR [aOR] 5.3; 95% CI 2.2-12.8) and was the only factor associated with severe neonatal morbidity (aOR 2.3; 95% CI 1.1-4.8).

Study details: Findings are from a retrospective observational study including 602 vaginal vertex deliveries in singleton pregnancies, which encountered shoulder dystocia that was managed with (n = 52) or without (n = 550) FM.

Disclosures: This study did not receive any funding. The authors declared no conflicts of interest.

Key clinical point: A dose of 30 mg oral extended-release nifedipine (ER-nifedipine) every 24 hours until delivery effectively reduced the receipt of treatment for acute severe hypertension in individuals with preeclampsia with severe features.

Major finding: A significantly lower proportion of individuals who received 30 mg ER-nifedipine vs placebo required ≥1 dose of acute hypertension therapy for severe blood pressure that sustained for ≥10 minutes (34.0% vs 55.1%; relative risk 0.62; 95% CI 0.39-0.97). ER-nifedipine vs placebo use led to numerically lower cesarean deliveries (20.8% vs 34.7%) and neonatal intensive care unit admissions (29.1% vs 47.1%).

Study details: Findings are from a phase 4 trial including 110 individuals with singleton or twin gestation undergoing labor induction for preeclampsia with severe features who were randomly assigned to receive 30 mg oral ER-nifedipine or placebo every 24 hours until delivery.

Key clinical point: Risk for shoulder dystocia was higher among women with gestational diabetes who showed a slowly improving glycemic control trajectory, highlighting the need for interventions that help achieve glycemic targets early after the diagnosis of gestational diabetes.

Major finding: Compared with women showing rapid improvements to attain optimal glycemic control, the risk for shoulder dystocia was higher among women showing slow improvements to attain suboptimal glycemic control (adjusted relative risk [aRR] 1.41; 95% CI 1.12-1.78) and was lower among women with stably optimal glycemic control from diagnosis to delivery (aRR 0.75; 95% CI 0.61-0.92).

Key clinical point: Risk for shoulder dystocia was higher among women with gestational diabetes who showed a slowly improving glycemic control trajectory, highlighting the need for interventions that help achieve glycemic targets early after the diagnosis of gestational diabetes.

Key clinical point: Use of low-dose aspirin significantly reduced preterm birth rates but had no significant effect on the risk for preeclampsia in pregnant women with chronic hypertension.

Major finding: In women with chronic hypertension, the use of low-dose aspirin vs placebo during pregnancy was associated with a significant reduction in preterm birth rates (22.2% vs 31.1%; odds ratio, 0.63; 95% CI 0.45-0.89) but a nonsignificant reduction in the risk for superimposed or preterm preeclampsia.

Study details: Findings are from a systematic review and meta-analysis of nine studies (retrospective cohort studies and randomized controlled trials) including 2150 women with chronic hypertension who received low-dose aspirin or placebo during pregnancy.

Disclosures: This study did not receive any specific funding. V Giorgione’s PhD was supported by a Marie Skłodowska-Curie grant unrelated to this study. The authors declared no conflicts of interest.
