Background: Kinetics of Tdap-induced maternally-derived antibodies in infants are poorly understood. Pre-Tdap era data suggest that maternal pertussis antibodies in infants have a half-life of approximately 5-6 weeks.
Methods: 34 mother-infant pairs had blood collected before maternal Tdap vaccination, 4 weeks later, at delivery (maternal and cord), and at infant ages 3 and 6 weeks from June 2014-March 2015.
Objective: To estimate the rate of readmissions for postpartum venous thromboembolism (VTE) during the first 30 days postdelivery between women with and without the immediate postpartum insertion of the etonogestrel contraceptive implant.
Methods: The Nationwide Readmissions Database from 2016 was used to identify women with a singleton delivery, immediate postpartum insertion of the etonogestrel contraceptive implant, and readmission for VTE within 30 days of discharge. Those with a prior history of VTE or anticoagulant therapy were excluded.
