Funded Projects

This study aims to determine how exposure to opioids and other substances affects the developing fetal brain and shapes later child cognitive outcomes. Researchers will collect neuroimaging and behavioral data, as well as measures of environmental exposures related to social equity, COVID-19, and socioeconomic factors. The project will reduce traditional barriers to participation by using innovative data collection methods and mobile labs to bring the research to underrepresented and marginalized communities. This approach aims to clarify the impact of substance exposure on child development through an equitable approach to research, with generalizable findings. The study will take place at Rhode Island Hospital, where participants will be drawn from a largely rural population.

Neonatal Opioid Withdrawal Syndrome (NOWS) is a condition that occurs when newborns are exposed to opioids during pregnancy. Symptoms often include tremors, excessive crying, sleep deprivation, and swallowing difficulties. Cases are rising, with a newborn affected by NOWS approximately every 15 minutes. Currently, healthcare providers in the United States lack standard, evidence-based treatments for NOWS. 

This project is part of a multi-center, randomized controlled clinical trial that directly compares NOWS treatments—morphine, methadone, and buprenorphine—and takes into account other types of non-drug therapies, such as behavioral interventions. The goal is to generate results that can inform clinical practice guidelines and give newborns with NOWS the best start possible. 

Arkansas is a rural state with the second highest opioid prescription rate in the nation and is in the top 3 states nationwide for opioid prescriptions to pregnant mothers. This site has extensive experience in opioid research and conducting multi-center clinical trials. It also provides care to a diverse population.

Despite increased efforts to understand the neurodevelopmental sequelae of in utero opioid and other substance exposure on long-term behavioral, cognitive, and societal outcomes, important questions remain, specifically, 1) How is brain growth disrupted by fetal substance and related pre- and post-natal exposures? and 2) How are these disrupted growth patterns causally related to later cognitive and behavioral outcomes? This project seeks to formulate an approach to addressing these key questions and decipher the individual and cumulative effect of these intertwined pre- and post-natal exposures on child neurodevelopment. First, researchers will address the legal, ethical, and mother-child care and support concerns implicit in this study. Next, they will integrate across our areas of neuroimaging expertise to develop, implement, and harmonize a multi-modal MRI and EEG protocol to assess maturing brain structure, function, and connectivity. Finally, researchers will develop and test advanced statistical approaches to model and analyze this multidimensional and longitudinal data.

The objective of the HBCD PRELUDE (Prenatal Experiences and Longitudinal Development) multi-site consortium is to characterize typical brain development from birth through childhood. All sites in this consortium will measure the influence of key biological and environmental factors on child social, cognitive, and emotional development. Researchers will assess how prenatal exposure to opioids and other substances, as well as other adverse environmental factors, affect brain development and other child health outcomes. The study site at the University of North Carolina, Chapel Hill will work with Wake Forest University to help recruit pregnant women with substance use disorders and enroll mother-infant dyads. This collaboration serves to expand participant diversity and extend recruitment to cover a larger region of North Carolina, a state hit hard by the opioid crisis.

The University of Alabama at Birmingham routinely treats newborns with NOWS and has been part of NICHD’s Neonatal Research Network (NRN) for more than 25 years. The center has an excellent track record of enrollment in clinical studies, with successful follow-up to 2 years of age and beyond.

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.

The HEALthy Brain and Child Development National Consortium (HBCD-NC) Administrative Core (HCAC) will coordinate efforts across all sites in the HBCD-NC consortium to ensure that the consortium meets its primary objective to establish a normative model of developmental trajectories over the first 10 years of life. The HBCD-NC will collect neural, behavioral, physiological, and psychological measures, as well as biospecimens, to characterize neurodevelopmental trajectories. The HCAC will oversee study design and monitor the progress of each site’s ability to carry out a common research protocol and will assemble and distribute a comprehensive research dataset to the scientific community. This administrative core is located at the University of California, San Diego.

This study will determine the feasibility of a multifaceted approach to recruitment of normal and high-risk pregnant women and their children. Three inter-related tasks will support this comprehensive feasibility study. First, an interdisciplinary summit will occur early in the study focused on how best to mitigate risks and maximize benefits to children and families recruited in a future cohort. Second, the feasibility of a multi-faceted recruitment strategy will be assessed. Third, select pregnancy and birth assessments will be collected from recruited participants in this feasibility study while leveraging data across early childhood from existing resources, to inform Phase II study planning. This Phase I of the FL-DECADE study will provide valuable planning and feasibility data to be used for the national efforts to build a large, prospective cohort.

A more than 5-fold increase in the incidence of neonatal abstinence syndrome has been reported since 2000. Preliminary studies show that prenatal opioid exposure is associated with increased risk of impaired neurodevelopment. Five institutions (Duke University, Arkansas Children’s Research Institute, Cincinnati Children’s Hospital, University of Illinois at Urbana–Champaign, and University of North Carolina at Chapel Hill) have formed a consortium to develop strategies for the Phase II HEALthy Brain and Child Development Study. Research teams will develop instruments and strategies (recruitment/retention protocols, assessment batteries, and novel tools); conduct pilot studies (fetal and postnatal imaging, advanced imaging harmonization and quality control, assessment administration, biosampling) to evaluate instruments; and analyze available data, including imaging, behavioral, cognitive, and maternal data from studies on early brain development, to guide the Phase II study design. Upon completion, the consortium aims to conduct the Phase II study.

The University of Louisville serves a large, diverse population that is disproportionately affected by the opioid crisis. Mothers and infants treated by the university’s healthcare team live in rural
and urban underserved regions where the frequency of opioid use during pregnancy is among the highest in the country, with a rate estimated at 3 times the national average.

The number of women misusing opioids during pregnancy has more than quadrupled in recent years, with fentanyl use rising to an all-time high. The exposure puts the fetus at serious risk for opioid withdrawal, as well as developmental and behavioral effects during infancy and childhood. This project will study the effects of fentanyl use during pregnancy on maternal physiology and stress, function of the placenta, pregnancy outcomes, as well as infant withdrawal symptoms, development, and stress. This research aims to identify new strategies for diagnosing, treating, and preventing opioid harm to the fetus and mother.

The Planning for the HEALthy Early Development Study will contribute to the design and recommended protocol for a future large-scale, multi-site research study to prospectively examine human brain, cognitive, behavioral, social, and emotional development of children beginning prenatally through ages 9–10 and to determine the impact of maternal pre- and postnatal substance use on short- and long-term development of children. The planning study will link investigators across 6 research sites who have complementary experience and expertise in the areas that are essential to designing the study. Planning activities will be accomplished using a coordinated set of 10 working groups. By the end of the planning phase, the 6 consortium sites will have produced and tested a recommended protocol for the future multi-site study and will have established feasibility of carrying out the study protocol at each of the 6 linked sites.
