Maternal asthma and allergic predisposition are associated with an increased risk of congenital heart defects in offspring, particularly ventricular septal defects. The risk of ventricular septal defects is evident in cases of allergic asthma and atopy, but not in nonallergic asthma.

In the Netherlands, the incidence of preterm birth in singletons is subject to seasonality. Pregnancies conceived in April and May have the highest incidences of preterm birth <37 weeks. Fetuses are at the highest risk for preterm birth between October and January and lowest in February and April. Annabelle L. van Gils, Anita C. Ravelli, Brenda M. Kazemier, Eva Pajkrt, Martijn A.

Maternal diabetes, fever, positive urinary or vaginal/cervical culture, fetal tachycardia, and decreasing short-term variation were associated with an increased risk for EONS in a PPROM population. A model combining these risk factors performed better at indicating EONS risk than the clinicians' suspicion of intra-amniotic infection.
