Objective Our objective is to describe the implications, anticipated and perceived, by providers in a level-IV neonatal intensive care unit (NICU) with immediate patient access to inpatient notes and test results in the wake of the 21st Century Cures Act (CCA). Study Design Using a mixed-method approach in February 2021, a preimplementation survey of neonatologists, neonatal fellows, nurse practitioners, and neonatal nurses reported their perspectives on the new 21st CCA and how they anticipated that it would change their practices, and the experience of families in the NICU. In the follow-up to implementation, a postsurvey was completed by staff reporting their experiences in July 2021. Thematic analysis was performed. Results In the preimplementation survey, staff reported the greatest perceived benefits of the changes to be an increase in families' ability to be part of the care team and prepare questions, and faster discussion of results by the care team. Also, staff's highest concerns were that family members may incorrectly interpret results delivered electronically without the context provided by the care team and be overwhelmed by the amount of information available. In the postimplementation survey, staff reported that the Act had less impact on their practice than they had anticipated preimplementation. Conclusion To maximize benefits and limit burdens to families and staff, care teams should consider a thoughtful approach to information sharing with family members in compliance with the 21st CCA. Key Points The impact of the 21 CCA on the NICU has not been studied. NICU staff have significant concerns related to the release of results to families. This study highlights the need to set expectations and provide family-centered care. [ABSTRACT FROM AUTHOR]

Pathogenic variants in HPRT1 lead to deficiency in hypoxanthine‐guanine phosphoribosyltransferase and are responsible for a spectrum of disorders. The severe phenotype is termed Lesch–Nyhan syndrome (LNS) and is inherited in an X‐linked recessive manner. Most individuals with LNS have profound intellectual and physical disabilities throughout life including self‐mutilating behaviors. Here, we present the case of a male infant who was diagnosed with LNS at 3 weeks of age via rapid exome sequencing (ES), which revealed a hemizygous maternally inherited deletion of at least 1.3 Mb of Xq26.3, including exons 2 to 9 of HPRT1. We discuss the critical time points leading to this diagnosis while highlighting his parents' values that guided the decision‐making. Genetic testing provided an early diagnosis for this infant that led to important considerations regarding goals of care in addition to raising new ethical concerns. This highlights the important role that early and rapid diagnostic genetic testing can play in helping families make difficult decisions. Additionally, this case highlights the complexity of discussing rare genetic diagnoses with families and facilitating critical discussions to empower the family toward making an informed decision.

There is a growing appreciation of the role of lung stem/progenitor cells in the development and perpetuation of chronic lung disease including idiopathic pulmonary fibrosis. Human amniotic epithelial cells (hAECs) were previously shown to improve lung architecture in bleomycin-induced lung injury, with the further suggestion that hAECs obtained from term pregnancies possessed superior anti-fibrotic properties compared with their preterm counterparts. In the present study, we aimed to elucidate the differential effects of hAECs from term and preterm pregnancies on lung stem/progenitor cells involved in the repair. Here we showed that term hAECs were better able to activate bronchioalveolar stem cells (BASCs) and type 2 alveolar epithelial cells (AT2s) compared with preterm hAECs following bleomycin challenge. Further, we observed that term hAECs restored TGIF1 and TGFß2 expression levels, while increasing c-MYC expression despite an absence of significant changes to Wnt/ß-catenin signaling. In vitro, term hAECs increased the average size and numbers of BASC and AT2 colonies. The gene expression levels of Wnt ligands were higher in term hAECs, and the expression levels of BMP4, CCND1 and CDC42 were only increased in the BASC and AT2 organoids co-cultured with hAECs from term pregnancies but not preterm pregnancies. In conclusion, term hAECs were more efficient at activating the BASC niche compared with preterm hAECs. The impact of gestational age and/or complications leading to preterm delivery should be considered when applying hAECs and other gestational tissue-derived stem and stem-like cells therapeutically.

Background: Despite advances in neonatal care, bronchopulmonary dysplasia (BPD) remains a significant contributor to infant mortality and morbidity. While human amnion epithelial cells (hAECs) have shown promise in small and large animal models of BPD, there is scarce information on long-term benefit and clinically relevant questions surrounding administration strategy remain unanswered. In assessing the therapeutic potential of hAECs, we investigated the impact of cell dosage, administration routes and timing of treatment in a pre-clinical model of BPD. Methods: Lipopolysaccharide was introduced intra-amniotically at day 16 of pregnancy prior to exposure to 65% oxygen (hyperoxia) at birth. hAECs were administered either 12 hours (early) or 4 days (late) after hyperoxia commenced. Collective lung tissues were subjected to histological analysis, multikine ELISA for inflammatory cytokines, FACS for immune cell populations and 3D lung stem cell culture at neonatal stage (postnatal day 7 and 14). Invasive lung function test and echocardiography were applied at 6 and 10 weeks of age. Results: hAECs improved the tissue-to-airspace ratio and septal crest density in a dose-dependent manner, regardless of administration route. Early administration of hAECs, coinciding with the commencement of postnatal hyperoxia, was associated with reduced macrophages, dendritic cells and natural killer cells. This was not the case if hAECs were administered when lung injury was established. Fittingly, early hAEC treatment was more efficacious in reducing interleukin-1β, tumour necrosis factor alpha and monocyte chemoattractant protein-1 levels. Early hAEC treatment was also associated with reduced airway hyper-responsiveness and normalisation of pressure-volume loops. Pulmonary hypertension and right ventricle hypertrophy were also prevented in the early hAEC treatment group, and this persisted until 10 weeks of age. Conclusions: Early hAEC treatment appears to be advantageous over late treatment. There was no difference in efficacy between intravenous and intratracheal administration. The benefits of hAEC administration resulted in long-term improvements in cardiorespiratory function. [ABSTRACT FROM AUTHOR]

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.

Objective: To estimate the association between the mode of respiratory support administered at 36 weeks' post-menstrual age (PMA) with time-to-liberation from respiratory support (LRS) in infants with grade 2/3 bronchopulmonary dysplasia (BPD)., Study Design: Daily respiratory support data were abstracted for infants born <32 weeks' gestation with grade 2/3 BPD enrolled in the Children's Hospitals Neonatal Database between 2017 and 2022. The main exposure was the mode of respiratory support received at 36 weeks' PMA: high flow nasal cannula >2 L/min (HFNC), continuous positive airway pressure (CPAP), non-invasive positive pressure ventilation (NIPPV), or mechanical ventilation (MV). The primary outcome was time-to-LRS, defined as the PMA when infants weaned to nasal cannula <2 L/min or room air for >2 days. The independent association between the main exposure and time-to-LRS was estimated using restricted mean survival time analysis., Results: Among 3,483 included infants from 41 centers, 17% received HFNC, 36% CPAP, 16% NIPPV, and 32% MV at 36 weeks' PMA. After censoring those who died (4.2%), survived with tracheostomy (7.6%), or were transferred to another facility (7.5%), the median (IQR) time-to-LRS differed between groups: HFNC 37 [37, 39]; CPAP 39 [37, 41] NIPPV 41[39, 45]; and MV 44 [40, 48] weeks' PMA (P<0.001). Across centers, a 10-fold difference in time-to-LRS was observed after adjustment for clinical risk factors., Conclusions: For infants with grade 2/3 BPD, the mode of respiratory support prescribed at 36 weeks' PMA and center of care were each associated with time-to-LRS independent of patient and clinical characteristics., (Copyright © 2024 Elsevier Inc.

The coronavirus disease 2019 (COVID-19) pandemic, resulting from infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has caused severe and widespread illness in adults, including pregnant women, while rarely infecting neonates. An incomplete understanding of disease pathogenesis and viral spread has resulted in evolving guidelines to reduce transmission from infected mothers to neonates. Fortunately, the risk of neonatal infection via perinatal/postnatal transmission is low when recommended precautions are followed. However, the psychosocial implications of these practices and racial/ethnic disparities highlighted by this pandemic must also be addressed when caring for mothers and their newborns. This review provides a comprehensive overview of neonatal-perinatal perspectives of COVID-19, ranging from the basic science of infection and recommendations for care of pregnant women and neonates to important psychosocial, ethical, and racial/ethnic topics emerging as a result of both the pandemic and the response of the healthcare community to the care of infected individuals.

Understanding mechanisms of childhood disease and development of rational therapeutics are fundamental to progress in pediatric intensive care specialties. However, Division Chiefs and Department Chairs face unique challenges when building effective laboratory-based research programs in Neonatal and Pediatric Intensive Care, owing to high clinical demands necessary to maintain competence as well as financial pressures arising from fund flow models and the current extramural funding climate. Given these factors, the role of institutional support that could facilitate successful transition of promising junior faculty to independent research careers is ever more important. Would standardized guidelines of such support provide greater consistency among institutions? We addressed preliminary questions during a national focus group, a workshop and a survey of junior and senior academicians to solicit recommendations for optimal levels of protected time and resources when starting an independent laboratory. The consensus was that junior faculty should be assigned no more than 8 wk clinical service and should obtain start-up funds of $500K-1M exclusive of a 5-y committed salary support. Senior respondents placed a higher premium on protected time than junior faculty.
