Uterus and cervix anatomical changes and cervix stiffness evolution throughout pregnancy.

The coordinated biomechanical performance, such as uterine stretch and cervical barrier function, within maternal reproductive tissues facilitates healthy human pregnancy and birth. Quantifying normal biomechanical function and detecting potentially detrimental biomechanical dysfunction (e.g.

Low-dose aspirin and racial disparities in spontaneous preterm delivery in low-risk individuals.

Background: Preterm birth is a leading cause of perinatal morbidity and mortality. There are significant racial disparities in the rates of preterm delivery in the United States, with Black individuals at disproportionately higher risk than their White counterparts. Although low-dose aspirin is currently under investigation for reducing the rates of preterm delivery, limited data are available on how the use of low-dose aspirin might affect racial and ethnic disparities in the rates of preterm delivery.

Delivery Outcomes and Postpartum Readmissions Associated with Ehlers-Danlos Syndrome.

Objective: Given that updated estimates of Ehlers-Danlos syndrome and risks for obstetric complications including postpartum readmission may be of public health significance, we sought to analyze associated obstetric trends and outcomes in a nationally representative population.

Study Design: The 2016 to 2020 Nationwide Readmissions Database was used for this retrospective cohort study. Delivery hospitalizations to women aged 15 to 54 with and without Ehlers-Danlos syndrome were identified.
