Higher YAP1 Levels Are Associated With Shorter Survival of Patients With Low Grade Astrocytoma.

Background/aim: Glioblastoma multiforme (GBM) is one of the most lethal types of brain cancer with a median survival of only 12 months due to its aggressiveness and lack of effective treatment options. Astrocytomas and oligodendrogliomas are classified as low-grade gliomas (LGG) and have the potential to progress into secondary GBM. YAP1 and TAZ are transcriptional co-activators of the hippo pathway and play an important role in tumorigenesis by controlling cell proliferation and differentiation.

Maternal Morbidity After Double Balloon Catheter Management of Cesarean Scar and Cervical Pregnancies.

We performed a retrospective cohort study of all Type 1 cesarean scar pregnancies (n=18) or cervical pregnancies (n=5) at an academic tertiary center after treatment with a cervical double balloon catheter from 2018 to 2022 to evaluate outcomes and maternal morbidity. Cervical double balloon catheter treatment was associated with no cases (95% confidence interval 0-16%) of maternal hemorrhage treated with transfusion, hysterectomy, or ICU admission. Treatment was successfully performed by nine different obstetrics and gynecology specialists.

Etiology and evaluation of stillbirth in patients with obesity.

Objective: Maternal obesity is a risk factor for stillbirth, but whether or not the etiology of stillbirth differs in gravidas with and without obesity is unknown. We categorized stillbirths in a contemporary cohort to test the hypothesis that the etiology of stillbirth is different in gravidas with and without obesity.

Methods: This retrospective cohort study included all gravidas with a stillbirth ≥20 weeks' gestation between 2010 and 2017 and a normal mid-trimester anatomic survey by ultrasound assessment at a large academic institution.

Clinical significance of umbilical artery intermittent vs persistent absent end-diastolic velocity in growth-restricted fetuses.

Background: Umbilical artery absent end-diastolic velocity indicates increased placental resistance and is associated with increased risk of perinatal demise and neonatal morbidity in fetal growth restriction. However, the clinical implications of intermittent vs persistent absent end-diastolic velocity are unclear.

Objective: We compared umbilical artery Doppler velocimetry changes during pregnancy and neonatal outcomes between pregnancies with fetal growth restriction and intermittent absent end-diastolic velocity and those with persistent absent end-diastolic velocity.

Obstetric Outcomes in Singleton Pregnancies with Abnormal Placental Cord Insertions.

Objective: There is wide variation in the management of pregnancies complicated by abnormal placental cord insertion (PCI), which includes velamentous cord insertion (VCI) and marginal cord insertion (MCI). We tested the hypothesis that abnormal PCI is associated with small for gestational age (SGA) infants.

Study Design: This is a retrospective cohort study of all pregnant patients undergoing anatomic ultrasound at a single institution from 2010 to 2017.
