This document is a collection of abstracts from the Journal of Neonatal - Perinatal Medicine. The abstracts cover various topics related to neonatal neurodevelopment and brain abnormalities in preterm infants. One study focuses on the use of MRI in predicting long-term outcomes in infants with Hypoxic Ischemic Encephalopathy. Another study explores the prediction of post-hemorrhagic ventricular dilatation in preterm infants with intraventricular hemorrhage. A third study examines the impact of cerebellar hemorrhage on the neurodevelopmental outcomes of extremely preterm infants. The fourth abstract compares the utility of early and late MRI in evaluating infants with Neonatal Encephalopathy. Additionally, there is a study investigating the impact of SARS-CoV-2 infection during pregnancy on neonatal neurological outcomes. Lastly, a study explores the hemodynamic responses associated with spontaneous neural activity in the early developing brain. These abstracts provide valuable insights into neonatal neurodevelopment and brain abnormalities in preterm infants. [Extracted from the article]

Aim Methods Results Conclusion Immune dysregulation and delayed onset of sleep wake cycling (SWC) are associated with worse outcome in neonatal encephalopathy (NE), however the association between sleep and immune dysfunction in NE remains unclear. Aimed to evaluate association of sleep and systemic inflammation with outcomes in NE.Amplitude‐integrated electroencephalography (aEEG) recordings were collected on infants undergoing therapeutic hypothermia (TH). Duration to onset of (SWC) and sleep quality (SQ) were examined. Blood samples collected during the first 2 days of life. Thirteen pro‐ and anti‐inflammatory serum cytokines were quantified. Adverse outcome defined as death or abnormal MRI brain.Earlier onset of SWC and better SQ had less adverse outcomes. SQ provided better prognostic value and showed better interobserver agreement compared to duration to SWC. Better SQ associated with lower cytokines EPO and interleukin (IL)‐1β. In infants with unfavourable outcome, shorter duration to SWC was associated with higher EPO and better SQ was associated with lower TNF‐α.Earlier onset of SWC or better SQ showed less systemic inflammation and fewer adverse outcomes. SQ during TH provided better prognostic information than time of onset of SWC. Modulation of circadian rhythm in infants with NE may have an immunomodulatory role, leading to improved outcomes.

Aim: Immune dysregulation and delayed onset of sleep wake cycling (SWC) are associated with worse outcome in neonatal encephalopathy (NE), however the association between sleep and immune dysfunction in NE remains unclear. Aimed to evaluate association of sleep and systemic inflammation with outcomes in NE., Methods: Amplitude-integrated electroencephalography (aEEG) recordings were collected on infants undergoing therapeutic hypothermia (TH). Duration to onset of (SWC) and sleep quality (SQ) were examined. Blood samples collected during the first 2 days of life. Thirteen pro- and anti-inflammatory serum cytokines were quantified. Adverse outcome defined as death or abnormal MRI brain., Results: Earlier onset of SWC and better SQ had less adverse outcomes. SQ provided better prognostic value and showed better interobserver agreement compared to duration to SWC. Better SQ associated with lower cytokines EPO and interleukin (IL)-1β. In infants with unfavourable outcome, shorter duration to SWC was associated with higher EPO and better SQ was associated with lower TNF-α., Conclusion: Earlier onset of SWC or better SQ showed less systemic inflammation and fewer adverse outcomes. SQ during TH provided better prognostic information than time of onset of SWC. Modulation of circadian rhythm in infants with NE may have an immunomodulatory role, leading to improved outcomes., (© 2024 The Author(s).
