Predictors for Development of Asphyxiated Neonates Treated With Therapeutic Hypothermia.
Acta Paediatr
January 2025
Center for Chronically Sick Children, Charité - Universitätsmedizin Berlin, Berlin, Germany.
Aim: To describe the long-term neurodevelopmental outcomes of asphyxiated neonates treated with hypothermia in association with neonatal magnetic resonance imaging (MRI) findings.
Methods: We evaluated, retrospectively, clinical and radiological single-centre data at 0, 2, and 5 years of age of 53 asphyxiated neonates born between 2005 and 2015. Neonatal cranial MRI was re-evaluated using the Weeke score ranging from 0 (normal finding) to 55 (cerebral devastation) by a single neuroradiologist blinded to patient outcomes.
Temporal variations in and predictive values of ABG results prior to in-hospital cardiac arrest.

In-hospital cardiac arrest (IHCA) has been understudied relative to out-of-hospital cardiac arrest. Further, studies of IHCA have mainly focused on a limited number of pre-arrest patient characteristics (e.g.

J Pediatr
January 2025
Department of Pediatrics, McGill University; Montreal Children's Hospital.
Objective: To assess variability among data elements collected among existing neonatal hypoxic-ischemic encephalopathy (HIE) data registries worldwide and to determine the need for future harmonization of standard common data elements.
Study Design: This was a cross-sectional study of data elements collected from current or recently employed HIE registry data forms. Registries were identified by literature search and email inquiries to investigators worldwide.
Normothermic Crystalloid Polarizing Cardioplegia Improves Systolic and Diastolic Function in a Porcine Model of Cardiopulmonary Bypass.

Previously, we showed that blood-based polarizing cardioplegia exerted beneficial cardioprotection during hypothermic ischemia; however, these positive effects of blood-based polarizing cardioplegia were reduced during normothermic ischemia compared to blood-based hyperkalemic (depolarizing) cardioplegia. This study compares crystalloid polarizing cardioplegia to crystalloid depolarizing cardioplegia in a normothermic porcine model of cardiopulmonary bypass; Methods: Twelve pigs were randomized to receive either normothermic polarizing ( = 7) or depolarizing ( = 5) crystalloid cardioplegia. After the initiation of cardiopulmonary bypass, normothermic arrest (34 °C, 60 min) was followed by 60 min of on-pump and 90 min of off-pump reperfusion.

Hibernation and torpor are not passive responses caused by external temperature drops and fasting but are active brain functions that lower body temperature. A population of neurons in the preoptic area was recently identified as such active torpor-regulating neurons. We hypothesized that the other hypothermia-inducing maneuvers would also activate these neurons.
