Selected Research

Enoxaparin dosing after cesarean delivery in morbidly obese women

In this prospective sequential cohort study, Dr. Overcash and colleagues compared the adequacy of venous thromboembolism prophylaxis based on anti-Xa concentrations of weight-based enoxaparin dosing versus body mass index (BMI)-stratified dosing in morbidly obese women after cesarean delivery. This study was published in Obstetrics and Gynecology (2015;125:1371-6. doi: 10.1097/AOG.0000000000000873).

Early second trimester weight gain in obese women predicts excessive gestational weight gain

In this observational prospective cohort study, Dr. Overcash and colleagues assessed gestational weight gain in obese women to determine whether weight gain at a certain point in pregnancy could identify women at risk for excessive gestational weight gain. This work was published in Maternal and Child Health (2015;19:2412-2418. doi: 10.1007/s10995-015-1760-8).

Maternal and fetal capillary malformation-arteriovenous malformation

In this work, Dr. Overcash and colleagues explored RASA1 mutations and the clinical presentation of a patient with capillary malformation-arteriovenous malformation and a fetus with non-immune hydrops fetalis. The results of this research have been published in the American Journal of Medical Genetics (2015;167A:2440-2443. doi: 10.1002/ajmg.a.37203).

Factors associated with gastroschisis outcomes

In this multi-center retrospective study, Dr. Overcash and colleagues from the University of California Fetal Consortium identified perinatal variables that were associated with adverse outcomes in newborns diagnosed prenatally with gastroschisis. This research was published in Obstetrics and Gynecology (2014;124:551-7. doi: 10.1097/AOG.0000000000000425).
