The Association Between Shirodkar Cerclage and Preterm Premature Rupture of Membranes in Singleton Pregnancies
Certain women with high-risk pregnancies undergo a cerclage placement, which is a surgical procedure intended to keep the cervix closed, prolong pregnancy, and prevent pregnancy loss or preterm birth. One of the classis risks of cerclage is the risk of membrane rupture (the “water breaking”) while the cerclage is in place. In this study, we found that the risk of this happening is only approximately 10%, and appears to be mostly due to the risk factors for preterm birth, and not actually the cerclage itself.
The Effect of Microbiome Exposure at Birth on Pediatric Outcomes Using a Twin Cohort Discordant for Microbiome Exposure at Birth
Abstract
The microbiome refers to the normal bacteria that live on our skin and in our bodies. There has been much written about the effect of differing microbiome exposures at birth and outcomes later in childhood and adulthood. In this study, we examined twins with differing microbiome exposure and found no differences at ages 2-10 years old, suggesting the importance of this variable may be overstated.

Serial Cervical Length Evaluation in Low-Risk Women with Shortened Cervical Lengths in the Midtrimester: How Many Will Dilate Prior to 24 Weeks?
For women diagnosed with a short cervix, there is controversy regarding the proper management and follow-up. In this study, we demonstrate that a significant proportion of women with a short cervix in the second trimester will ultimately have a dilated cervix, which is a more concerning situation and often requires different management. These results indicate that one should continue surveillance after the diagnosis of a short cervix.
Induction of Labor versus Cesarean Delivery in Twin Pregnancies
Abstract
For women with twin pregnancies, we have previously shown that outcomes are similar for attempted vaginal delivery as compared to cesarean delivery. In this study, we demonstrate that this remains true even for women with twin pregnancies who require induction of labor.

Subchorionic Hematomas and Adverse Pregnancy Outcomes among Twin Pregnancies
Abstract
Subchorionic hematomas, or subchorionic hemorrhages, are common ultrasound findings in early pregnancy. However, their significance is uncertain. Some believe they increase the risk of many pregnancy complications, including pregnancy loss / miscarriage. In prior studies we demonstrated that subchorionic hematoma does not appear to increase the risk adverse outcomes in singleton pregnancies.
In this study, we present similar results regarding twin pregnancies – subchorionic hematoma does not appear to increase the risk of adverse outcomes in twin pregnancies.

Association Between First-Trimester Subchorionic Hematomas and Adverse Pregnancy Outcomes After 20 Weeks of Gestation in Singleton Pregnancies
Subchorionic hematomas, or subchorionic hemorrhages, are common ultrasound findings in early pregnancy. However, their significance is uncertain. Some believe they increase the risk of many pregnancy complications, including pregnancy loss / miscarriage. In a prior study we demonstrated that subchorionic hematoma does not appear to increase the risk of miscarriage in singleton pregnancies.
In this study, we present similar results regarding other adverse pregnancy outcomes – subchorionic hematoma does not appear to increase the risk of adverse outcomes later in pregnancy.
