Altered cord serum 25-hydroxyvitamin D signaling and placental inflammation is associated with pre-term birth.

Problem: Vitamin D is well-known for having anti-inflammatory and immunomodulatory properties. Impaired maternal vitamin D status has been known to increase the risk of adverse pregnancy outcomes like pre-term birth. The present study aims to evaluate the impact of fetal cord serum 25-hydroxyvitamin D-mediated signaling in mediating inflammatory responses in placenta during pre-term birth.
