Uneven Distribution of Purkinje Cell Injury in the Cerebellar Vermis of Term Neonates with Hypoxic-Ischemic Encephalopathy.

In term neonates with hypoxic-ischemic encephalopathy (HIE), cerebellar injury is becoming more and more acknowledged. Animal studies demonstrated that Purkinje cells (PCs) are especially vulnerable for hypoxic-ischemic injury. In neonates, however, the extent and pattern of PC injury has not been investigated.

Biomimetic astrocyte cell membrane-fused nanovesicles for protecting neurovascular units in hypoxic ischemic encephalopathy.

Hypoxic ischemic encephalopathy (HIE) refers to neonatal hypoxic brain injury caused by severe asphyxia during the perinatal period. With a high incidence rate and poor prognosis, HIE accounts for 2.4% of the global disease burden, imposing a heavy burden on families and society.

The serum biomarkers NSE and S100B predict intracranial complications and in-hospital survival in patients undergoing veno-venous ECMO.

Neurological complications in patients undergoing veno-venous extracorporeal membrane oxygenation (V-V ECMO) are challenging, with new intracranial pathologies posing a grave risk. We aimed to evaluate the utility of neuron-specific enolase (NSE) and S100B biomarkers for predicting outcomes in new-onset intracranial pathology during V-V ECMO. A retrospective analysis spanning 2013-2021 at a German university hospital was conducted.

Acupuncture for hypoxic ischemic encephalopathy in neonates.

Background: Peripartum asphyxia affects three to five per 1000 live births, with moderate or severe hypoxic ischemic encephalopathy (HIE) occurring in 0.5 to 1 per 1000 live births, and is associated with high mortality and morbidity. Therapeutic hypothermia is an effective treatment, but alternative therapies such as acupuncture are also used.

Oligodendrocyte Progenitor Cell Transplantation Reduces White Matter Injury in a Fetal Goat Model.

Background: Preterm white matter injury (PWMI) is the most common type of brain injury in preterm infants, in which, oligodendrocyte progenitor cells (OPCs) are predominantly damaged. In this study, human OPCs (hOPCs) were administered to a fetal goat model of PWMI to examine the differentiation potential and therapeutic effects of the cells on PWMI.

Methods: Preterm goat fetuses were subjected to hypoxic-ischemia (HI) via intermittent umbilical cord occlusion (5 min × 5).

Therapeutic Hypothermia and Its Role in Preserving Brain Volume in Term Neonates with Perinatal Asphyxia.

Perinatal asphyxia is a major cause of neonatal morbidity and mortality, often resulting in hypoxic-ischemic encephalopathy (HIE) with long-term neurodevelopmental impairments. While therapeutic hypothermia has emerged as a promising intervention to reduce brain damage, its specific impact on key brain structures and long-term neurodevelopmental outcomes remains underexplored. This study aims to evaluate the effects of therapeutic hypothermia on brain volumetry, cortical thickness, and neurodevelopment in term neonates with perinatal asphyxia.

Survive and Thrive: Outcomes of Children Enrolled in a Follow-Up Clinic for Small and Sick Newborns in Rural Rwanda.

Introduction: Children born small or sick are at risk of death and poor development, but many lack access to preventative follow-up services. We assessed the impact of Pediatric Development Clinics (PDC), which provide structured follow-up after discharge from hospital neonatal care units, on children's survival, nutrition and development in rural Rwanda.

Methods: This quasi-experimental study compared a historic control group to children receiving PDC in Kayonza and Kirehe districts.

Prenatal Alcohol Exposure and Transient Systemic Hypoxia-Ischemia Result in Subtle Alterations in Dendritic Complexity in Medial Frontal Cortical Neurons in Juvenile and Young Adult Rat Offspring in a Pilot Study.

Prenatal alcohol exposure (PAE) is associated with long-term neurodevelopmental deficits resulting in impaired executive functioning and motor control. Intriguingly, PAE has been linked with an increased risk of transient systemic hypoxia-ischemia (TSHI), which alone results in suboptimal fetal growth and neurodevelopmental consequences. Here, using two translationally relevant preclinical models, we investigated the short-term and lasting effects of PAE and TSHI on the morphology of the medial prefrontal cortex (mPFC), a region important in executive function, and tested whether PAE interacts with TSHI to produce a distinct pattern of injury relative to either condition alone.

Development of a model to predict electroencephalographic seizures in neonates with hypoxic ischemic encephalopathy treated with therapeutic hypothermia.

Objective: Electroencephalographic seizures (ES) are common in neonates with hypoxic-ischemic encephalopathy (HIE), but identification with continuous electroencephalographic (EEG) monitoring (CEEG) is resource-intensive. We aimed to develop an ES prediction model.

Methods: Using a prospective observational study of 260 neonates with HIE undergoing CEEG, we identified clinical and EEG risk factors for ES, evaluated model performance with area under the receiver operating characteristic curve (AUROC), and calculated test characteristics emphasizing high sensitivity.

Dilapan-S versus Standard Methods for Cervical Ripening in Term Pregnancies: An Individual Patient Data Meta-Analysis.

Objectives: Dilapan-S is a cervical ripening agent approved by the FDA that has been found to be just as effective as other agents and can be utilized for outpatient ripening. No large-scale studies have been conducted to compare cesarean delivery rates between Dilapan-S and other ripening methods. Our objective was to combine these trials to compare cesarean delivery rates for Dilapan-S with other cervical ripening methods, overall and in sub-groups.

Placental inflammatory response and association with the severity of neonatal hypoxic ischemic encephalopathy.

Background: Placental lesions are associated with worse neonatal outcomes, but their association with neonatal hypoxic-ischemic encephalopathy (HIE), including the full range of severity from mild to severe HIE, has not been well described.

Objective: To determine the association of acute and chronic placental lesions with mild versus moderate to severe HIE; secondarily, to assess the impact of multiple placental lesions on severity of HIE.

Methods: This retrospective study of prospectively collected data included neonates born at ≥36 weeks, with a birth weight of >1800 g, diagnosed with HIE between January 2012 and November 2022.

Neurodevelopment of Critical ILL Neonates at the Age of 12 Months.

Critically ill neonates who survive are often left with dire consequences. Cerebral palsy, other neurological and motor deficiencies, intellectual disability, and various degrees of cognitive and behavioral deficiencies all result from neonatal critical diseases. We investigated psychomotor development in 20 children with hypoxic-ischemic encephalopathy (HIE), and as newborns often have multiple comorbidities, the following as well: HIE with respiratory distress syndrome (RDS), infections, hypo and hyperglycemia and hypocalcemia.

Temporal dynamics of neonatal hypoxic-ischemic encephalopathy injuries on magnetic resonance imaging.

Moderate to severe perinatal hypoxic-ischemic encephalopathy occurs in ~1 to 3/1000 live births in high-income countries and is associated with a significant risk of death or neurodevelopmental disability. Detailed assessment is important to help identify high-risk infants, to help families, and to support appropriate interventions. A wide range of monitoring tools is available to assess changes over time, including urine and blood biomarkers, neurological examination, and electroencephalography.

Risk Factors and Predictors of Outcomes in Hypoxic-Ischemic Encephalopathy in Neonates.

Background Hypoxic-ischemic encephalopathy (HIE) in neonates results from oxygen deprivation at birth, often leading to long-term neurological issues like cerebral palsy. Early detection is key to improving outcomes, but HIE remains a significant cause of neonatal complications. Here we aim to study the risk factors and predictors of outcome in moderate to severe HIE in inborn Term babies in the neonatal intensive care unit (NICU) Methods This prospective observational study was conducted in the NICU at a tertiary care center between August 2022 and July 2024.

Brain and brain blood vessels histological description in autopsies of fetuses/neonates born to mothers with hypertension during pregnancy. A case-control study.

Background: Children born to women with hypertension during pregnancy have a two to threefold increased risk of developing cognitive disorders compared to children born to women without hypertension. However, structural changes in the central nervous system of these children remain poorly understood. We aim to compare the brain histological findings from autopsies of neonates and fetuses born to women with and without hypertension during pregnancy.

Synergistic Clinico-Radiological Assessment of Term Newborns Afflicted by Birth Asphyxia in a Tertiary Medical Center: A Prospective Observational Study.

Background and objectives Hypoxic-ischemic encephalopathy (HIE) remains a critical concern in newborns, with therapeutic hypothermia (TH) serving as a key treatment strategy. However, assessing long-term outcomes requires a comprehensive approach, as children may develop neuropsychological and learning challenges even in the absence of noticeable motor impairments. This study aims to explore the correlation between electroencephalography (EEG) and neuroimaging findings with the clinical severity of HIE.

Prophylactic Fetal Creatine Supplementation Improves Post-Asphyxial EEG Recovery and Reduces Seizures in Fetal Sheep: Implications for Hypoxic-Ischemic Encephalopathy.

Objective: Hypoxic-ischemic encephalopathy (HIE) is a major cause of perinatal brain injury. Creatine is a dietary supplement that can increase intracellular phosphocreatine to improve the provision of intracellular adenosine triphosphate (ATP) to meet the increase in metabolic demand of oxygen deprivation. Here, we assessed prophylactic fetal creatine supplementation in reducing acute asphyxia-induced seizures, disordered electroencephalography (EEG) activity and cerebral inflammation and cell death histopathology.

Utility of Cranial Ultrasound to Investigate Brain Injury in Hypoxic-Ischemic Encephalopathy.

Background: With increasing availability of brain magnetic resonance imaging (MRI) in high-income countries, cranial ultrasound (cUS) is used less frequently to evaluate infants with hypoxic-ischemic encephalopathy (HIE). This study aimed to correlate findings of brain injury on early postnatal cUS with brain injury on neonatal brain MRI performed as part of routine clinical care for near-term and term infants with moderate to severe HIE.

Methods: This was a retrospective cohort study comparing early postnatal cUS and later neonatal brain MRI using scoring systems with prognostic validity to assess brain injury in near-term/term infants with moderate or severe HIE.
