Filter by:Crying is a vital communication signal for the baby. Product of a complex physiological process, it reflects not only the organization and functioning of the cortical central nervous system and the function of sympathetic and parasympathetic autonomic regulation but also the integrity of three entities: the lungs responsible for ventilatory mechanics and respiratory rhythm, the larynx and its vocal cords as a phonatory organ, and the oropharyngeal tract guaranteeing the resonance of the sound emitted by the vocal cords. Crying is usually caused by pain, discomfort, hunger, or separation from parents or other caregivers. Crying carries essential information from birth, the expression of which depends closely on the neuroanatomical and functional brain integrity of the child. On a bioacoustic level, crying consists of sequences of complex acoustic signals produced by the vocal folds and filtered by the vocal tract. The vibration frequency of the vocal cords determines the cry's fundamental frequency f0 (and the harmonic frequencies), which is responsible for its more or less low or high pitch. Other acoustic cues also characterize each baby's cry.
This study is designed to answer one of the fundamental gaps in knowledge in the resuscitation of preterm infants at birth: What is the optimal target oxygen saturation (SpO2) range that increases survival without long-term morbidities? Oxygen (O2) is routinely used for the stabilization of preterm infants in the delivery room (DR), but its use is linked with mortality and several morbidities including bronchopulmonary dysplasia (BPD). To balance the need to give sufficient O2 to correct hypoxia and avoid excess O2, the neonatal resuscitation program (NRP) recommends initiating preterm resuscitation with low (≤ 30%) inspired O2 concentration (FiO2) and subsequent titration to achieve a specified target SpO2 range. These SpO2 targets are based on approximated 50th percentile SpO2 (Sat50) observed in healthy term infants. However, the optimal SpO2 targets remain undefined in the preterm infants. Recent data suggest that the current SpO2 targets (Sat50) may be too low. The investigators plan to conduct a multicenter RCT of Sat75 versus Sat50 powered for survival without BPD. The investigators will randomize 700 infants, 23 0/7- 30 6/7 weeks' GA, to 75th percentile SpO2 goals (Sat75, Intervention) or 50th percentile SpO2 goals (Sat50, control). Except for the SpO2 targets, all resuscitations will follow NRP guidelines including an initial FiO2 of 0.3. In Aim 1, the investigators will determine whether targeting Sat75 compared to Sat50 increases survival without lung disease (BPD). In addition, the investigators will compare the rates of other major morbidities such as IVH. In Aim 2, the investigators will determine whether targeting Sat75 compared to Sat50 increases survival without neurodevelopmental impairment at 2 years of age. In Aim 3, the investigators will determine whether targeting Sat75 compared to Sat50 decreases oxidative stress.
Early developmentally-based behavioral intervention has well-established positive effects and is recommended as the standard of care to support early brain maturation, health, and development. However, few neonatal intensive care units (NICUs) provide this early intervention. H-HOPE (Hospital to Home: Optimizing the Preterm Infant's Environment) has established efficacy, and has a standardized protocol, making it ready for widespread implementation. The infant-directed component of H-HOPE provides Auditory (voice), Tactile (moderate touch massage), Visual (eye to eye), and Vestibular (rocking) stimulation starting when infants are ready for social interaction. The parent-directed component of H-HOPE includes participatory guidance and support to help parents engage with infants in the NICU and the transition to home. In this NIH-funded research, H-HOPE improved growth, developmental maturity and mother-infant interaction, and reduced initial hospitalization costs and acute care visits through 6-weeks corrected age. This research tests whether H-HOPE can be implemented and sustained in five diverse NICUs, using a Type 3 Hybrid design to evaluate both implementation processes and effectiveness. The specific aims are to: 1) Identify the degree of implementation success; 2) Evaluate the effectiveness of H-HOPE for infants, hospital costs from H-HOPE enrollment until discharge, and parents, compared to a pre-implementation comparison cohort; and 3) Determine influences (facilitators and barriers) associated with implementation success and H-HOPE effectiveness, guided by the Consolidated Framework for Implementation Research (CFIR). An incomplete stepped-wedge design guides staggered roll-out for five clinical sites. Each NICU completes the CFIR implementation steps (Planning and Engaging, Executing, and Reflecting and Evaluating), followed by 6 months of Sustaining. For Aim 1, degree of implementation success is determined every two months as Sustainability (still offering H-HOPE), Reach (% of eligible parent/infant dyads receiving H-HOPE) and Degree of Implementation (mean H-HOPE services received per parent-infant unit) (primary implementation outcomes). For Aim 2, effectiveness is analyzed using generalized linear mixed models for infant, cost, and parent outcomes (primary outcomes: infant growth at discharge and acute care visits from discharge to 6-weeks corrected age). Propensity score analysis is used to make the pre- and post-implementation comparable. For Aim 3, a mixed methods analyses is used to identify influences from H-HOPE records and interviews that are associated with implementation success and effectiveness at each site and across sites. This is the first time implementation in a NICU is guided by the evidence-based CFIR framework, and results will make a major contribution to implementation science. This study will produce an evidence-based implementation strategy and Toolkit to disseminate nationwide. Widespread H-HOPE implementation will make a significant change in clinical practice and improve preterm infant health and health care costs.
This study aims to explore the developmental of the gut microbiome in preterm infants as they grow and mature
Preterm and very preterm infants are at risk of developing encephalopathy of prematurity and long-term neurodevelopmental delay. Magnetic resonance imaging (MRI) allows the characterization of specific features of encephalopathy of prematurity, including structural changes of brain white matter and gray matter. This study wants to investigate important evidence that early repeated high-dose rhEPO(5250 IU/kg) treatment improves long-term neurological outcomes in very preterm infants and without obvious adverse effects.
Background: fluctuation of cerebral blood flow and oxygenation in neonates who undergo intensive care is an important risk factor for risk of neurodevelopmental impairment. Near infrared spectroscopy (NIRS) allow direct measurements of cerebral tissue oxygenation. Automated Fraction of Inspired Oxygen (FiO2) adjustment can maintain arterial oxygen saturation (SpO2) within a target range and may reduce risk of fluctuation of cerebral oxygenation. Aim of this study: to evaluate the efficacy of automated FiO2 adjustment in maintaining SpO2 within a target range and in reducing the risk of cerebral tissue hypo-oxygenation due to SpO2 fluctuations in preterm infants on invasive or non invasive respiratory support with supplemental oxygen.
This study uses frequency domain near-infrared spectroscopy coupled with diffuse correlation spectroscopy (FDNIRS-DCS) technology for monitoring cerebral blood flow (CBF) and cerebral oxygen metabolism (CMRO2) at the bedside for newborns with germinal matrix-intraventricular hemorrhage (GM-IVH) and/or post-hemorrhagic hydrocephalus (PHH) in comparison to newborns with hydrocephalus of a different etiology (VC) and healthy controls (HC). We hypothesize that baseline cerebral metabolic dysfunction is a better biomarker for GM-IVH and PHH severity and response to PHH treatment. This is a Boston Children's Hospital (BCH)-institutional review board(IRB) approved, multi-site study that includes collaboration with Brigham and Women's Hospital (BWH) and Beth Israel Deaconess Medical Center (BIDMC). Pei-Yi Lin receives funding from The National Institute of Health (NIH) to support the study and is the overall principal Investigator (PI) overseeing the study.
