Methods: A case series is reported with patients referred to the Texas Children's Fetal Center for evaluation and management of suspected spontaneous TAPS without concomitant twin-to-twin syndrome from 2014 to 2023.

Serum exosomal microRNA pathway activation in placenta accreta spectrum: pathophysiology and detection.

Background: Placenta accreta spectrum disorders are a complex range of placental pathologies that are associated with significant maternal morbidity and mortality. A diagnosis of placenta accreta spectrum relies on ultrasonographic findings with modest positive predictive value. Exosomal microRNAs are small RNA molecules that reflect the cellular processes of the origin tissues.

Outcomes of fetal lower urinary tract obstruction based on timing of oligohydramnios onset.

Objective: Fetal Lower Urinary Tract Obstruction (LUTO) is associated with oligohydramnios and significant fetal morbidity, resulting in poor lung development and perinatal death. However, oligohydramnios may develop at different gestational periods, and the impact of timing on fetal outcomes remains unknown. Our objective was to characterize the impact onset of oligohydramnios had on prenatal outcomes.

Risk factors of massive blood transfusion (MTP) in cesarean hysterectomy for placenta accreta spectrum.

Background: Placenta Accreta Spectrum (PAS) represents a particularly morbid condition for which blood transfusion is the leading cause. Delivery by cesarean hysterectomy is recommended for the management of PAS. Massive Transfusion Protocols (MTP) in obstetrics vary in definition and implementation.

Impact of Race/Ethnicity and Insurance Status on Obstetric Outcomes: Secondary Analysis of the NuMoM2b Study.

Objective: This study aimed to investigate the impact of race/ethnicity and insurance status on obstetric outcomes in nulliparous women.

Study Design: Secondary analysis of the Nulliparous Pregnancy Outcomes Study Monitoring Mothers-To-Be. Obstetric outcomes included the development of a hypertensive event during pregnancy, need for a cesarean section, delivery of a preterm neonate, and postpartum hemorrhage.

An obstetric-specific surgical Apgar score predicts maternal morbidity from cesarean hysterectomy for placenta accreta spectrum.

Objective: Placenta accreta spectrum (PAS) is a continuum of placental conditions characterized by significant maternal and neonatal morbidity. Tools to accurately predict postoperative morbidity have been lacking due to the hemodynamic changes of pregnancy. The surgical Apgar score (SAS) is a 10-point scale that assesses heart rate, mean arterial pressure, and estimated blood loss.

Risk of Severe Maternal Morbidity in Patients with Placenta Accreta Spectrum Disorders Referred from Rural Communities to a Regional Placenta Accreta Spectrum Center.
