PARTO Study
Predicting Adequate Response to Oxytocin
While a lot of factors have been associated with a person having postpartum hemorrhage (PPH), our clinical tools for predicting PPH currently miss 1 in every 2-3 cases of hemorrhage. That is, the birth was consider low-risk for hemorrhage but it happened anyway. Our PARTO project aims to study biomarkers linked to oxytocin function in the body for predicting PPH. Click here for a recent blog about the science behind this study. Click here to see the participant video for our currently enrolling study at Banner University Medical Center in Tucson and Phoenix, AZ in English or en Español.

BioBAYB Study
Biological Rhythms Before & After Your Birth
In this study, we examine how physiological data gathered from wearable devices worn during pregnancy could be useful in tracking pregnancy health and outcomes. Using machine learning and artificial intelligence can be useful in analyzing the complex signals of life during gestation. See our publications (NPJ Digital Medicine , BMC Pregnancy & Childbirth) and / blog here.

Coming Soon: Breathing for Two Study
Inspiratory Muscle Strength Training for Supporting Human Blood Pressure in Pregnancy
High blood pressure during pregnancy is a leading cause of maternal morbidity in the United States, with few preventive options beyond aspirin and largely reactive treatment. Proactive interventions could improve maternal outcomes and reduce healthcare costs by preventing avoidable hospitalizations, preterm birth, and chronic disease. This study will examine upper airway strength training—a brief, portable, low-burden intervention shown to improve blood pressure in non-pregnant adults.

The Clock is Ticking
Biological Age in the Era of Advanced Maternal Age
The term "Advanced Maternal Age" usually is applied to anyone giving birth who is 35 years or older. A growing number of births are occurring later in life as people pursue educational or economic milestones prior to having children. However, most pregnancies after 35 don't have complications and many people under 35 have age-related problems like diabetes, hypertension or other factors that influence their health in pregnancy. This study is using biomarkers from DNA, called "epigenetic clocks" to examine biological age and learn if advanced biological age is linked to social stress during pregnancy and birth related complications.

Midwives as Mechanisms
How does the care we provide support physiology?
Certified Nurse-Midwives and other midwifery professionals hold the perspective that labor and birth and normal parts of reproductive physiology. Data on midwifery-led care can help us understand how the processes of care, which emphasize watchful waiting in the absence of pathology in pregnancy, can help achieve healthy birth outcomes like a lower Cesarean birth rate for appropriate clients. Midwives work in conjunction with health systems and obstetricians and may attend births in hospital, birth centers or at home. See our publications for past studies on midwifery care outcomes.
