Association Between First-Trimester Subchorionic Hematomas and Pregnancy Loss 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 this study of almost 3000 women, we found that Subchorionic hematoma does not increase the risk of pregnancy loss prior to 20 weeks.  This information is reassuring as nearly 20% of women will have this finding on ultrasound.

Cervical Length, Cervical Dilation, and Gestational Age at Cerclage Placement and the Risk of Preterm Birth in Women Undergoing Ultrasound or Exam Indicated Shirodkar Cerclage

Certain high-risk women require cerclage placement in pregnancy to lower the risk of a pregnancy loss or preterm birth and we have previously published our vast experience with this procedure (  In this study we examined if there were any differences in cerclage outcomes, based on the cervical  length, cervical dilation, or gestational age at the time of the procedure.

Weight Gain and Pregnancy Outcomes in Underweight Women with Twin Gestations

We have previously shown the critical importance of adequate pregnancy weight gain for women with twin pregnancies  However, most data has been for women who enter pregnancy with a normal weight, as defined by the pre-pregnancy body mass index (BMI).  In this study, we found that women who enter pregnancy underweight should be recommended the same weight gain as women with normal pre-pregnancy weight.

The Association Between High-Normal Blood Pressure and the Development of Preeclampsia in Twin Pregnancies

Women with twin pregnancies are at increased risk of preeclampsia.  In this study we found that women  with twin pregnancies and blood pressure readings that were normal, but in the upper range of normal, are at significantly increased risk of developing preeclampsia and need to be monitored carefully.

The Association Between Intended Mode of Delivery and Maternal Morbidity in Twin Pregnancies

We have published several studies demonstrating that planned vaginal delivery of twins is associated with similar neonatal outcomes as compared to planned  cesarean delivery ( and (  In this study, we demonstrate that maternal outcomes are similar or better with planned vaginal delivery, as compared to planned cesarean delivery.  This gives further support to women with twin pregnancies attempting a vaginal delivery, if clinically appropriate.

Risk Factors for Positive Postpartum Depression Screen in Women With Private Health Insurance and Access to Care

Postpartum depression is a common and potentially devastating condition for a new mother.  There are many known risk factors for postpartum depression, but many of them are related to poor access to health care .  In this study, we sought to find risk factors for postpartum depression amongst a large cohort of women with private health insurance and excellent access to care.
