Funded Projects

Both an infant’s ability to regulate their emotions and infant-parent interactions are critical to healthy brain and behavioral development. Accurate assessment of these factors for research in laboratory settings is technically difficult and burdensome for participants. Next-generation methods that can be used at home, including wearable sensors and machine learning approaches, promise to make it easier to assess infants with prenatal substance exposures. This project will use remote sensing technologies and machine learning to characterize dynamic real-time infant emotion regulation and infant-caregiver interactions throughout the day and in the home.

Use of remote data collection in developmental research can make it easier for families to participate in such research and increase sociodemographic diversity of participants. The goal of this project is to validate remote methods for testing early cognitive development, particularly attention and memory skills, in 4-, 8-, and 12-month-old infants from traditionally underrepresented populations in neuroscience research. The project will integrate multiple types of data to improve remote measurement of infant cognition within the home and will help expand understanding of developmental trajectories and mechanisms across diverse environments and contexts.

Opioid use disorder during pregnancy is associated with poor infant outcomes including neonatal opioid withdrawal syndrome (NOWS) and impaired brain development during childhood. This project will use advanced imaging techniques to measure inflammation in the placenta and evaluate brain structure of the developing fetus. These data will be combined with measures of infant NOWS and neurodevelopmental outcomes at birth and 1 year of age. This research will explore the value of these imaging methods as diagnostic tools for infants exposed to opioids during pregnancy. The research will also study the effect of opioids on the placenta’s ability to provide oxygen to the growing fetus as well as the potential for inflammation to damage the placenta and harm development of the fetal brain. 

Exposure of the developing fetus to opioids during pregnancy in women with opioid use disorder can lead to inefficient placenta function and impaired fetal brain development and neurodevelopmental outcomes. This project will measure molecules that circulate within maternal blood to identify specific indicators (biomarkers) of maternal health such as inflammation and changes in placental gene activity. The research will include a focus on specialized molecules released from the placenta called exosomes that carry information about the health of the placenta. These data will be combined with neurodevelopmental measures of infants at 1 year of age. Together, these studies will provide new molecular predictors (biomarkers) of placenta and fetal health.

Opioid use during pregnancy is associated with significant harmful health outcomes for infants including preterm birth, neonatal opioid withdrawal syndrome, and impaired brain-related problems. This project will combine advanced imaging of the fetal brain and placenta, genetics, and tissue and blood samples from the placenta to determine how opioid use during pregnancy affects development of the fetal brain and placenta. This research will provide novel and early molecular indicators (biomarkers) to as well as identify new strategies for diagnosing, treating, and preventing opioid harm to the fetus and mother.

Opioid use during pregnancy is associated with significant harmful health outcomes for infants including preterm birth, neonatal opioid withdrawal syndrome (NOWS), and impaired brain-related problems. Not all infants exposed to opioids develop NOWS, and there is a need for better diagnostic tests. This project will study specialized cell structures called vesicles that are released from the placenta, fetal brain, and central nervous system to communicate information about health of the fetus and placenta. This research on vesicles will be combined with data about NOWS diagnosis up to 1 month after birth. The research aims to generate molecular indicators (biomarkers) that predict which newborns develop NOWS, toward guiding safe and effective treatment for these newborns.

Opioid use during pregnancy is associated with adverse outcomes for pregnant individuals and offspring. The mechanisms through which these outcomes arise and the consequences of prenatal opioid exposure on child health and development remain largely unexplored. The HEALthy Brain and Child Development (HBCD) Study is a nationwide longitudinal prospective study of early child development that will assess a broad spectrum of biological, behavioral, social, and health factors among 7,500 pregnant women and their children from pregnancy to mid-childhood. This supplement will expand the biospecimen collection of the HBCD protocol at the University of North Carolina at Chapel Hill to include delivery specimens (placenta, cord tissue, and cord blood). This will provide an unprecedented resource-generating opportunity for the larger scientific community to comprehensively evaluate mechanisms that mediate the connection between substance use during pregnancy and adverse neonatal, infant, and/or maternal health outcomes and inform innovative preventive strategies.
