Neonatal visual assessment in congenital heart disease: A pilot study

This study assessed neonatal visual maturity in infants with congenital heart disease (CHD) and its predictive value for neurodevelopmental outcomes. Neonates with CHD underwent a standardized visual assessment before and after cardiopulmonary bypass surgery. Visual maturity was rated as normal versus abnormal by means of normative reference data. Twelve-month neurodevelopment was assessed with the Bayley-III. Twenty-five healthy controls served as the reference group. Neonatal visual assessment was performed in five neonates with CHD preoperatively and in 24 postoperatively. Only postoperative assessments were considered for further analysis. Median [IQR] age at assessment was 27.0 [21.5, 42.0] days of life in postoperative neonates with CHD and 24.0 [15.0, 32.0] in controls. Visual performance was within reference values in 87.5% in postoperative CHD versus 90.5% in healthy controls (p = 1.0). Visual maturity was not predictive of neurodevelopment at 12 months. These results demonstrate the limited feasibility and predictive value of neonatal visual assessments in CHD

Creative Music Therapy and Neurodevelopmental Outcomes in Pre-term Infants at 2 Years: A Randomized Controlled Pilot Trial

Impaired neurodevelopment is increasingly recognized as a major health issue in children born prematurely. Creative music therapy (CMT) intends to prevent and or reduce neurobehavioral deficits in pre-term infants using musical stimulation and socio-emotional co-regulation. We conducted a randomized, clinical pilot CMT trial to test feasibility and to examine long-term neurodevelopmental outcomes in pre-term infants (NCT02434224: https://clinicaltrials.gov/ct2/show/NCT02434224). Eighty-two pre-term infants were randomized either to CMT or standard care. A specially trained music therapist provided family-integrating CMT via infant-directed singing during hospitalization. Fifty-six infants underwent follow-up at 2 years of corrected age. No significant beneficial nor adverse effects of CMT were identified in routine clinical neurodevelopmental measures (Bayley-III Scales of Infant and Toddler Development and the standardized neurological examination). Longer term follow-up (5 years) and larger future studies are recommended to elucidate possible long-term effects of music in relation to more sensitive outcomes including executive function, detailed language processing and social-emotional development

Parents' Experiences on Therapeutic Hypothermia for Neonates With Hypoxic-Ischemic Encephalopathy (HIE): A Single-Center Cross-Sectional Study

Background and Objectives: The purpose of the study is to assess parental experiences of therapeutic hypothermia for moderate to severe hypoxic-ischemic encephalopathy with the goal of improving local clinical practice guidelines and fostering family-integrated care in neonates with hypoxic-ischemic encephalopathy. Methods: This single-center retrospective cross-sectional study included neonates and their parents registered in the Swiss National Asphyxia and Cooling Register between 2011 and 2021. Based on a literature review, an anonymous survey of parents of neonates with hypoxic-ischemic encephalopathy was developed and conducted using an online survey tool. Descriptive statistics were used to analyze the survey results. Results: The overall response rate to this survey was 64% (46/72). Sufficient information about hypoxic-ischemic encephalopathy was reported by 78% (36/46) of parents and sufficient information about the process of therapeutic hypothermia by 87% (40/46) of parents. The majority of parents indicated the need for, and at least a satisfactory perception of, professional (91%; 42/46) and emotional (87%; 40/46) support. Parents identified fostering family involvement and regular family communication that focuses on family integrated care as areas for improvement. Conclusions: There is still an unmet need for multidisciplinary teams to provide professional, empathetic, high quality, and family-integrated care to families with a neonate receiving therapeutic hypothermia for moderate or severe hypoxic-ischemic encephalopathy

Brain volumes predict neurodevelopment in adolescents after surgery for congenital heart disease

Patients with complex congenital heart disease are at risk for neurodevelopmental impairments. Evidence suggests that brain maturation can be delayed and pre- and postoperative brain injury may occur, and there is limited information on the long-term effect of congenital heart disease on brain development and function in adolescent patients. At a mean age of 13.8 years, 39 adolescent survivors of childhood cardiopulmonary bypass surgery with no structural brain lesions evident through conventional cerebral magnetic resonance imaging and 32 healthy control subjects underwent extensive neurodevelopmental assessment and cerebral magnetic resonance imaging. Cerebral scans were analysed quantitatively using surface-based and voxel-based morphometry. Compared with control subjects, patients had lower total brain (P = 0.003), white matter (P = 0.004) and cortical grey matter (P = 0.005) volumes, whereas cerebrospinal fluid volumes were not different. Regional brain volume reduction ranged from 5.3% (cortical grey matter) to 11% (corpus callosum). Adolescents with cyanotic heart disease showed more brain volume loss than those with acyanotic heart disease, particularly in the white matter, thalami, hippocampi and corpus callosum (all P-values < 0.05). Brain volume reduction correlated significantly with cognitive, motor and executive functions (grey matter: P < 0.05, white matter: P < 0.01). Our findings suggest that there are long-lasting cerebral changes in adolescent survivors of cardiopulmonary bypass surgery for congenital heart disease and that these changes are associated with functional outcom

Levetiracetam versus Phenobarbital for Neonatal Seizures: A Retrospective Cohort Study

BACKGROUND Although phenobarbital (PB) is commonly used as a first-line antiseizure medication (ASM) for neonatal seizures, in 2015 we chose to replace it with levetiracetam (LEV), a third-generation ASM. Here, we compared the safety and efficacy of LEV and PB as first-line ASM, considering the years before and after modifying our treatment protocol. METHODS We conducted a retrospective cohort study of 108 neonates with electroencephalography (EEG)-confirmed seizures treated with first-line LEV or PB in 2012 to 2020. RESULTS First-line ASM was LEV in 33 (31%) and PB in 75 (69%) neonates. The etiology included acute symptomatic seizures in 69% of cases (30% hypoxic-ischemic encephalopathy, 32% structural vascular, 6% infectious, otherwise metabolic) and neonatal epilepsy in 22% (5% structural due to brain malformation, 17% genetic). Forty-two of 108 (39%) neonates reached seizure freedom following first-line therapy. Treatment response did not vary by first-line ASM among all neonates, those with acute symptomatic seizures, or those with neonatal-onset epilepsy. Treatment response was lowest for neonates with a higher seizure frequency, particularly for those with status epilepticus versus rare seizures (P < 0.001), irrespective of gestational age, etiology, or EEG findings. Adverse events were noted in 22 neonates treated with PB and in only one treated with LEV (P < 0.001). CONCLUSIONS Our study suggests a potential noninferiority and a more acceptable safety profile for LEV, which may thus be a reasonable option as first-line ASM for neonatal seizures in place of PB. Treatment should be initiated as early as possible since higher seizure frequencies predispose to less favorable responses

Perioperative Course and Socioeconomic Status Predict Long-Term Neurodevelopment Better Than Perioperative Conventional Neuroimaging in Children with Congenital Heart Disease

OBJECTIVE The objective of the study was to compare the use of neonatal conventional brain magnetic resonance imaging (MRI) with that of clinical factors and socioeconomic status (SES) to predict long-term neurodevelopment in children with severe congenital heart disease (CHD). STUDY DESIGN In this prospective cohort study, perioperative MRIs were acquired in 57 term-born infants with CHD undergoing cardiopulmonary bypass surgery during their first year of life. Total brain volume (TBV) was measured using an automated method. Brain injury severity (BIS) was assessed by an established scoring system. The neurodevelopmental outcome was assessed at 6 years using standardized test batteries. A multiple linear regression model was used for cognitive and motor outcomes with postoperative TBV, perioperative BIS, CHD complexity, length of hospital stay, and SES as covariates. RESULTS CHD diagnoses included univentricular heart defect (n = 15), transposition of the great arteries (n = 33), and acyanotic CHD (n = 9). Perioperative moderate-to-severe brain injury was detected in 15 (26%) patients. The total IQ was similar to test norms (P = .11), whereas the total motor score (P < .001) was lower. Neither postoperative TBV nor perioperative BIS predicted the total IQ, but SES (P < .001) and longer hospital stay (P = .004) did. No factor predicted the motor outcome. CONCLUSION Although the predictive value of neonatal conventional MRIs for long-term neurodevelopment is low, duration of hospital stay and SES better predict the outcome in this CHD sample. These findings should be considered in initiating early therapeutic support

Tract-based spatial statistics to assess the neuroprotective effect of early erythropoietin on white matter development in preterm infants

In a randomized double-blind placebo-controlled trial, O'Gorman et al. show that administration of erythropoietin within the first 42 hours after preterm birth improves white matter development in preterm infants. Improvements are seen in the corpus callosum, the anterior and posterior limbs of the internal capsule, and the corticospinal tract bilaterall

Development and validation of a sensor prototype for near-infrared imaging of the newborn brain

Imaging brain oxygenation is crucial for preventing brain lesions in preterm infants. Our aim is to build and validate a near-infrared optical tomography (NIROT) sensor for the head of neonates. This sensor, combined with an optoacoustic device, will enable quantitative monitoring of the structural and functional information of the brain. Since the head of preterm infants is small and fragile great care must be taken to produce a comfortable and compact device in which a sufficient number of light sources and detectors can be implemented. Here we demonstrate our first prototype. Heterogeneous silicone phantoms were produced to validate the prototype's data acquisition, data processing, and image reconstruction. Reconstructed optical properties agree well with the target values. The mechanical performance of the new NIROT sensor prototype confirms its suitability for the clinical application

Similarities and Differences in the Neurodevelopmental Outcome of Children with Congenital Heart Disease and Children Born Very Preterm at School Entry

OBJECTIVE: To describe the similarities and differences in the neurodevelopmental outcome of children with congenital heart disease (CHD) undergoing cardiopulmonary bypass surgery compared with children born very preterm (VPT) at school entry. STUDY DESIGN: IQ, motor abilities, behavior, and therapy use were assessed in 155 children with CHD as part of a prospective, single-center, longitudinal study, and in 251 children born VPT as part of a national follow-up register at the same center. Group differences were tested using independent t-tests and χ$^{2}$-tests. Equivalence testing was used to investigate similarities between the groups. RESULTS: Mild (ie, 70 ≤ IQ < 85) and severe intellectual impairments (ie, IQ < 70) occurred in 17.4% and 4.5% of children with CHD compared with 22.1% and 5.5% in children VPT, respectively. Motor and behavioral functions were impaired in 57.0% and 15.3% of children with CHD compared with 37.8% and 11.5% of children born VPT, respectively. Children with CHD had poorer global motor abilities (d = -0.26) and poorer dynamic balance (d = -0.62) than children born VPT, and children born VPT had poorer fine motor abilities than children with CHD (d = 0.34; all P < .023). Peer problems were statistically similar between the groups (P = .020). Therapies were less frequent in children with CHD compared with children born VPT (23.4% vs 40.3%; P < .001). CONCLUSIONS: Children with CHD undergoing cardiopulmonary bypass surgery and children born VPT share an overall risk for neurodevelopmental impairments that manifest in different domains. Despite this, children with CHD receive fewer therapies, indicating a lack of awareness of the neurodevelopmental burden these children face

Association of perinatal sentinel events, placental pathology and cerebral MRI in neonates with hypoxic-ischemic encephalopathy receiving therapeutic hypothermia

OBJECTIVE: Placental pathology might provide information on the etiology of hypoxic-ischemic encephalopathy (HIE). To evaluate the association of perinatal sentinel events (PSE), placental pathology and cerebral MRI in cooled neonates with moderate/severe HIE. STUDY DESIGN: Retrospective analysis of 52 neonates with HIE registered in the Swiss National Asphyxia and Cooling Register 2011-2019. PSE and Non-PSE groups were tested for association with placental pathology. Placental pathology categories were correlated with MRI scores. RESULTS: In total, 14/52 neonates (27%) had a PSE, 38 neonates (73%) did not have a PSE. There was no evidence for an association of occurrence of PSE and placental pathologies (p = 0.364). Neonates with high MRI scores tended to have more often chronic pathologies in their placentas than acute pathologies or normal placentas (p = 0.067). CONCLUSION: Independent of the occurrence of PSE, chronic placental pathologies might be associated with more severe brain injury and needs further study
