    Case Definitions for Conditions Identified by Newborn Screening Public Health Surveillance
    (2018) Sontag, Marci K.; Sarkar, Deboshree; Comeau, Anne M.; Hassell, Kathryn; Botto, Lorenzo D.; Parad, Richard; Rose, Susan R.; Wintergerst, Kupper A.; Smith-Whitley, Kim; Singh, Sikha; Yusuf, Careema; Ojodu, Jelili; Copeland, Sara; Hinton, Cynthia F.
    Newborn screening (NBS) identifies infants with rare conditions to prevent death or the onset of irreversible morbidities. Conditions on the Health and Human Services Secretary’s Recommended Uniform Screening Panel have been adopted by most state NBS programs, providing a consistent approach for identification of affected newborns across the United States. Screen-positive newborns are identified and referred for confirmatory diagnosis and follow-up. The designation of a clinically significant phenotype precursor to a clinical diagnosis may vary between clinical specialists, resulting in diagnostic variation. Determination of disease burden and birth prevalence of the screened conditions by public health tracking is made challenging by these variations. This report describes the development of a core group of new case definitions, along with implications, plans for their use, and links to the definitions that were developed by panels of clinical experts. These definitions have been developed through an iterative process and are piloted in NBS programs. Consensus public health surveillance case definitions for newborn screened disorders will allow for consistent categorization and tracking of short- and long-term follow-up of identified newborns at the local, regional, and national levels.

    Evaluation of a web-based portal to improve resident education by neonatology fellows
    (Co-Action Publishing, 2014) Lakshmanan, Ashwini; Leeman, Kristen; Brodsky, Dara; Parad, Richard
    Background: Integration of web-based educational tools into medical training has been shown to increase accessibility of resources and optimize teaching. We developed a web-based educational portal (WBEP) to support teaching of pediatric residents about newborn medicine by neonatology fellows. Objectives: 1) To compare residents’ attitudes about their fellow-led education in the NICU pre- and post-WBEP; including assessment of factors that impact their education and usefulness of teaching tools. 2) To compare fellow utilization of various teaching modalities pre- and post-WBEP. Design/methods We queried residents about their attitudes regarding fellow-led education efforts and various teaching modalities in the NICU and logistics potentially impacting effectiveness. Based on these data, we introduced the WBEP – a repository of teaching tools (e.g., mock code cases, board review questions, journal articles, case-based discussion scenarios) for use by fellows to supplement didactic sessions in a faculty-based curriculum. We surveyed residents about the effectiveness of fellow teaching pre- and post-WBEP implementation and the type of fellow-led teaching modalities that were used. Results: After analysis of survey responses, we identified that residents cited fellow level of interest as the most important factor impacting their education. Post-implementation, residents described greater utilization of various teaching modalities by fellows, including an increase in use of mock codes (14% to 76%, p<0.0001) and journal articles (33% to 59%, p=0.02). Conclusions: A web-based resource that supplements traditional curricula led to greater utilization of various teaching modalities by fellows and may encourage fellow involvement in resident teaching.

    NIDCAP improves brain function and structure in preterm infants with severe intrauterine growth restriction
    (Nature Publishing Group, 2012) Als, Heidelise; Duffy, Frank; McAnulty, Gloria; Butler, Samantha; Lightbody, L; Kosta, S; Weisenfeld, Neil; Robertson, Richard; Parad, Richard; Ringer, Steven; Blickman, J G; Zurakowski, David; Warfield, Simon
    Objective: The effect of NIDCAP (Newborn Individualized Developmental Care and Assessment Program) was examined on the neurobehavioral, electrophysiological and neurostructural development of preterm infants with severe intrauterine growth restriction (IUGR). Study Design: A total of 30 infants, 27–33 weeks gestation, were randomized to control (C; N=17) or NIDCAP/experimental (E; N=13) care. Baseline health and demographics were assessed at intake; electroencephalography (EEG) and magnetic resonance imaging (MRI) at 35 and 42 weeks postmenstrual age; and health, growth and neurobehavior at 42 weeks and 9 months corrected age (9 months). Results: C and E infants were comparable in health and demographics at baseline. At follow-up, E infants were healthier, showed significantly improved brain development and better neurobehavior. Neurobehavior, EEG and MRI discriminated between C and E infants. Neurobehavior at 42 weeks correlated with EEG and MRI at 42 weeks and neurobehavior at 9 months. Conclusion: NIDCAP significantly improved IUGR preterm infants' neurobehavior, electrophysiology and brain structure. Longer-term outcome assessment and larger samples are recommended.

    Innate immune activation in neonatal tracheal aspirates suggests endotoxin-driven inflammation
    (Nature Publishing Group, 2012) Nathe, Katheryn; Mancuso, Christy J.; Parad, Richard; Van Marter, Linda; Martin, Camilia; Stoler-Barak, Liat; Philbin, Victoria J.; Phillips, Michele F.; Palmer, Christine D.; Levy, Ofer
    Background:: Tracheal aspirates (TAs) from critically ill neonates accumulate bacterial endotoxin and demonstrate mobilization of endotoxin-binding proteins, but the potential bioactivity of endotoxin in TAs is unknown. We characterized innate immune activation in TAs of mechanically ventilated neonates. Methods: Innate immune activation in TAs of mechanically ventilated neonates was characterized using a targeted 84-gene quantitative real-time (qRT) PCR array. Protein expression of cytokines was confirmed by multiplex assay. Expression and localization of the endotoxin-inducible antimicrobial protein Calgranulin C (S100A12) was assessed by flow cytometry. Endotoxin levels were measured in TA supernatants using the Limulus amoebocyte lysate assay. Results:: Analyses by qRT-PCR demonstrated expression of pattern recognition receptors, Toll-like receptor-nuclear factor κB and inflammasome pathways, cytokines/chemokines and their receptors, and anti-infective proteins in TA cells. Endotoxin positivity increased with postnatal age. As compared with endotoxin-negative TAs, endotoxin-positive TAs demonstrated significantly greater tumor necrosis factor (TNF), interleukin (IL)-6, IL-10, and serpin peptidase inhibitor, clade E, member 1 (SERPINE1) mRNA, and IL-10, TNF, and IL-1β protein. Expression of S100A12 protein was localized to TA neutrophils. Conclusion:: Correlation of endotoxin with TA inflammatory responses suggests endotoxin bioactivity and the possibility that endotoxin antagonists could mitigate pulmonary inflammation and its sequelae in this vulnerable population.
