Pharmacokinetics and Placental Transfer of Caffeine

The goal of this study is to learn how a pregnant person's body processes caffeine and how much caffeine crosses the placenta to the baby. A small dose of caffeine will be given to each pregnant participant before delivery. Blood will be drawn to measure caffeine levels in the pregnant mother. Blood will also be taken from the placenta and from the newborn to measure caffeine levels. This data will be used to form a computer model of the metabolism of caffeine during pregnancy.

Prediction of Preterm Delivery With Serial Cervical Length Measurements After Threatened Preterm Labor

Prospective cohort study on pregnant women discharged from the hospital after the first episode of threatened preterm labor. Cervical length (CL) will be measured with transvaginal US upon initial presentation (i.e at the time of hospital admission), at the time of hospital discharge, and respectively 2, 4, 8 and 12 weeks later. Pregnant women undelivered after the 1st episode of threatened preterm labor will be invited to participate in the study if CL upon discharge is \< 25 mm. The study will investigate the potential association between cervical shortening over time and time of delivery, to assess if spontaneous preterm delivery can be predicted by CL.

Comparing Two Prophylactic Antibiotic Protocols in Women With Term Prolonged Pre-labor Rupture of Membrane and Preterm Labor

This randomized prospective trial aimed to compare 2 prophylactic antibiotic regiment (ampicillin alone versus ampicillin plus gentamycin) in term prolonged pre-labor rupture of membrane and in preterm deliveries and examine related obstetrical outcome and infectious morbidity
