Funded Projects

Due to the opioid misuse epidemic across the nation, more infants are being exposed to narcotics during fetal life and developing neonatal opioid withdrawal syndrome (NOWS) in the neonatal period. Critical gaps remain in our knowledge with respect to best practices for identifying and managing infants with NOWS and no large-scale studies have been published on treatments undertaken and later outcomes of infants with NOWS. To address these gaps in knowledge, the Advancing Clinical Trials in Neonatal Opioid Withdrawal Syndrome (ACT NOW) study will evaluate treatment options and improve clinical care of infants with NAS/NOWS. This collaborative effort will conduct two trials: 1) Eating, Sleeping, Consoling for Neonatal Withdrawal (ESC-NOW): a Function-Based Assessment and Management Approach (ESC Study); and 2) Pragmatic, Randomized, Blinded Trial to Shorten Pharmacologic Treatment of Newborns With Neonatal Opioid Withdrawal Syndrome (NOWS) (Weaning Study).

The goal of this proposal is to launch an innovative, multi-modal neuroimaging program that will investigate the longitudinal trajectory of the neurodevelopment of irritability across the preschool period. Differentiating clinically salient irritability from developmentally normative temperamental variation has proven to be a difficult task. This is made even more challenging during the preschool period, when irritability has hit its normative peak and measuring neurodevelopment is impeded by methodological constraints. This research will (1) identify specific biomarkers underlying preschool vulnerability for psychopathology by examining neural maturation in executive function as a predictor for clinical outcome; and (2) examine how the parenting environment moderates this vulnerability, with the overarching objective of identifying aberrant irritable trajectories as the foundation for future brain-based behavioral intervention. Primary analyses will (1) probe underlying executive function as a predictor of clinical outcome; and (2) examine parent-child neural synchrony as a predictor of executive function maturation.

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.

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 HEALthy Brain and Child Development National Consortium (HBCD-NC) will establish a normative model of developmental trajectories over the first 10 years of life. All sites in the HBCD-NC will carry out a common research protocol and will assemble and distribute a comprehensive research dataset to the scientific community. The HBCD-NC will collect neural, behavioral, physiological, and psychological measures, as well as biospecimens, to characterize neurodevelopmental trajectories. Most participants will be recruited in the second trimester of pregnancy, with a smaller subset recruited at birth, and followed for the first 10 years of life. The Pennsylvania State University study site is in a region hard hit by opioid and methamphetamine use disorders and will recruit mother-infant pairs from largely rural communities.

The HEALthy Brain and Child Development National Consortium (HBCD-NC) Data Coordinating Center (HDCC) will provide data management and oversight to all HBCD-NC sites to ensure the consortium’s primary objective of establishing a normative template of developmental trajectories over the first 10 years of life is met. The HBCD-NC will collect neural, behavioral, physiological, and psychological measures, as well as biospecimens, to characterize neurodevelopmental trajectories. The HDCC will coordinate data collection, data quality, data harmonization, data sharing, and data analysis efforts that are central to the consortium’s ability to implement a common research protocol. The HDCC will assemble all data across the consortium sites and distribute a comprehensive and well curated research dataset to the scientific community at large. The HDCC is tightly integrated with the HEALthy Brain and Child Development Administrative Core (HCAC) and includes a multi-institution investigative team at the University of Minnesota, University of California, San Diego, and Washington University at St Louis.

Exposure to prescription opioids during pregnancy can alter growth of the fetus and cause persistent neurological problems during childhood. This project will identify biological underpinnings of oxycodone exposure on health of the placenta, brain development of the fetus, and behavioral problems observed in early infancy. This research will also assess whether melatonin supplementation can limit these harmful outcomes. Overall, the research aims to characterize the health effects of oxycodone used during pregnancy, as well as to point to new tools and molecular indicators (biomarkers) for diagnosing, treating, and preventing opioid harm to the fetus and mother.

The University of Maryland College Park study site is midway between Washington, DC, and Baltimore, Maryland, and will recruit a diverse sample of mother-infant pairs from across the region.

Opioid use during pregnancy is associated with harmful health outcomes for infants including preterm birth, neonatal opioid withdrawal syndrome, and brain-related problems. This project will carry out an in-depth investigation of the effects of opioid use during pregnancy including changes to health of the placenta, inflammation in the fetus, as well as behavioral and movement-related outcomes during the first year of life. This research will contribute to fundamental knowledge about how the placenta and brain work together as well as identify new strategies for diagnosing, treating, and preventing opioid harm to the fetus and mother.

The majority of participants will be recruited in the second trimester of pregnancy, with a smaller subset recruited at birth, and followed for the first decade of life. The University of Vermont study site will recruit mother-infant dyads from a rural area in Vermont, a state in which nearly one-third of neonatal hospitalizations are for neonatal abstinence syndrome (NAS).

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 first ten years of life are accompanied by rapid changes to the developing brain and cognitive abilities. Complex interacting factors including genetics, early-life exposure to substances, family and social interactions, and home and community environments can affect brain and cognitive development. Three linked projects aim to develop effective research protocols to lay a foundation for a future HEALthy Brain and Cognitive Development (HBCD) birth cohort study. Project 1 will develop protocols for recruitment and retention of a diverse sample of pregnant and postpartum women with oversampling of mothers with prenatal opioid use. Project 2 will identify ethical, legal, and regulatory challenges for investigations in this vulnerable population and define effective solutions to enable recruitment and study of these participants. Project 3 will develop and evaluate protocols for acquiring high-quality, quantitative neuroimaging measures with magnetic resonance imaging and functional near infrared spectroscopy and assess effective strategies for measuring cognitive performance in young children, including those exposed to opioids.
