Weight Gain in Twin Pregnancies and Adverse Outcomes
Twin pregnancies are at increased risk of fetal growth restriction, which is when babies are born smaller than expected, usually due to poor transport of nutrients from the mother to the baby (or babies) across the placenta. There are few known interventions to reduce the risk of growth restriction in twin pregnancies, but in this study we demonstrated that improved weight gain was associated with a lower risk of growth restriction in twin pregnancies.
Gestational Age at Cervical Length and Fetal Fibronectin Assessment and the Incidence of Spontaneous Preterm Birth in Twins
At MFMA and Carnegie Imaging, we utilize cervical length and fetal fibronectin (fFN) screening in patients at increased risk for preterm birth, such as twin pregnancies. This 2015 publication in the Journal of Ultrasound in Medicine is the basis for our twin preterm birth calculator (www.mfmnyc.com/twin) and allows patients and doctors to predict the risk of preterm birth in twins using these simple, low-risk tests.
First-Trimester Anueploidy Risk Assessment: The Impact of Comprehensive Counseling and Same-Day Results on Patient Satisfaction, Anxiety, and Knowledge
At Carnegie Imaging, women undergoing aneuploidy risk assessment (screening for Down Syndrome and other genetic conditions) have the option of Instant Risk Assessment (IRA), which allows women to receive their final results and counseling by one of our Maternal Fetal Medicine specialists on the day of their 11-13 week nuchal translucency ultrasound at Carnegie Imaging. With traditional aneuploidy screening, patients do not receive their results until a week later, generally from their referring provider’s office. In this 2010 publication in the American Journal of Perinatology, we demonstrated that women undergoing IRA had better understanding of aneuploidy screening, less anxiety, and more satisfaction than women who underwent traditional aneuploidy screening.
Ultrasound-indicated cerclage: Shirodkar vs. McDonald
Cervical cerclage is a procedure performed to reduce the risk of preterm birth in certain high-risk pregnancies. There are two techniques for this procedure, the McDonald cerclage and the Shirodkar cerclage. Traditionally, it was unknown which procedure type was superior. In this 2012 publication we showed that the Shirodkar type, which is the preferred method in our practice, was associated with superior outcomes.
Outcomes of emergency or physical examination-indicated cerclage in twin pregnancies compared to singleton pregnancies
Cervical cerclage is a procedure performed to reduce the risk of preterm birth in certain high-risk pregnancies. Despite its wide spread use, there is much controversy over which circumstances cerclage is actually beneficial. One such difficult clinical scenario is a patient with a dilated cervix in the second trimester. In this 2014 publication in the European Journal of Obstetrics and Gynecology, we reported our experience with cerclage in a series of patients with singleton and twin pregnancies and a dilated cervix in the second trimester and demonstrated excellent outcomes in this group of patients.
The association between maternal weight gain and spontaneous preterm birth in twin pregnancies
Twin pregnancies are at increased risk of several pregnancy complications, with the two most common being preterm birth and fetal growth restriction. In this study we demonstrated that simple nutritional interventions in twin pregnancies might be able to improve birthweight as well as lower the risk of preterm birth. This is why we place great emphasis on proper maternal nutrition in twin pregnancies.
