A prior report on hypothermia for neonatal hypoxic–ischemic encephalopathy showed a reduced rate of death or disability at 18 to 22 months of age. In this report of outcomes at 6 to 7 years, rates of death or an IQ below 70 were nonsignificantly lower with hypothermia than with usual care. Moderate or severe neonatal hypoxic–ischemic encephalopathy is associated with a high incidence of death or motor and sensory disability in children. 1 – 5 Children with encephalopathy are at risk for cognitive deficits even in the absence of functional deficits. Survivors without disability have delayed entry into primary school and fine-motor dysfunction and behavioral abnormalities. Hypothermia to 33 to 34°C for 72 hours, when initiated within 6 hours after birth among infants of more than 35 weeks' gestational age with hypoxic–ischemic encephalopathy, has been shown to reduce the risk of death or disability and increase the rate of survival free of disability . . .

It has been suggested that neurological problems more frequent in those born preterm are expressed prior to birth, but owing to technical limitations, this has been difficult to test in humans. We applied novel fetal resting-state functional MRI to measure brain function in 32 human fetuses in utero and found that systems-level neural functional connectivity was diminished in fetuses that would subsequently be born preterm. Neural connectivity was reduced in a left-hemisphere pre-language region, and the degree to which connectivity of this left language region extended to right-hemisphere homologs was positively associated with the time elapsed between fMRI assessment and delivery. These results provide the first evidence that altered functional connectivity in the preterm brain is identifiable before birth. They suggest that neurodevelopmental disorders associated with preterm birth may result from neurological insults that begin in utero.

Aim To determine the association between 10 min Apgar scores and 6–7-year outcomes in children with perinatal hypoxic-ischaemic encephalopathy (HIE) enrolled in the National Institute of Child Health and Human Development Neonatal Research Network (NICHD NRN) whole body cooling randomised controlled trial (RCT). Methods Evaluations at 6–7 years included the Wechsler Preschool and Primary Scale of Intelligence III or Wechsler Intelligence Scale for Children IV and Gross Motor Functional Classification Scale. Primary outcome was death/moderate or severe disability. Logistic regression was used to examine the association between 10 min Apgar scores and outcomes after adjusting for birth weight, gestational age, gender, outborn status, hypothermia treatment and centre. Results In the study cohort (n=174), 64/85 (75%) of those with 10 min Apgar score of 0–3 had death/disability compared with 40/89 (45%) of those with scores >3. Each point increase in 10 min Apgar scores was associated with a significantly lower adjusted risk of death/disability, death, death/IQ <70, death/cerebral palsy (CP) and disability, IQ<70 and CP among survivors (all p<0.05). Among the 24 children with a 10 min Apgar score of 0, five (20.8%) survived without disability. The risk-adjusted probabilities of death/disability were significantly lower in cooled infants with Apgar scores of 0–3; there was no significant interaction between cooling and Apgar scores (p=0.26). Conclusions Among children with perinatal HIE enrolled in the NICHD cooling RCT, 10 min Apgar scores were significantly associated with school-age outcomes. A fifth of infants with 10 min Apgar score of 0 survived without disability to school age, suggesting the need for caution in limiting resuscitation to a specified duration.

Objectives: Describe the details of the clinical presentation, diagnostic challenges, and management of a female neonate with neonatal severe hyperparathyroidism (NSHPT). Methods: This case report was developed from a retrospective chart review. The female infant was born to consanguineous parents—first cousins, with multiple prenatal concerns, including gestational diabetes, intrauterine growth restriction, polyhydramnios, and suspicion of a hypoplastic left atrium on prenatal echocardiogram (ECHO). Following a planned C‐section at 37 weeks gestation, the neonate exhibited moderate respiratory distress with subcostal retractions. On physical examination, craniotabes, a bell‐shaped chest, and a continuous machinery‐type murmur were noted. Results: Evaluation at birth revealed a large Patent Ductus Arteriosus and significant demineralization of skeletal structures with atypical rib morphology. Lab work at 24 h of life (HOL) showed elevated serum calcium level (14.3 mg/dL), ionized calcium—iCal (2.32 mmol/L), and normal 25‐OH Vitamin D (54.2 ng/mL). A comprehensive skeletal survey uncovered generalized osteopenia, metaphyseal lucencies, and evidence of healing fractures. Repeat lab work at 43 HOL, showed serum calcium of 18.0 mg/dL, iCal 2.67 mmol/L, and elevated parathyroid hormone (PTH) of 2116 pg/mL. Diagnosis of NSHPT was established based on laboratory findings. Molecular testing confirmed a homozygous variant (c.1744T >A; p.Cys582Ser) in the calcium‐sensing receptor (CaSR) gene which confirmed the diagnosis of NSHPT. NSHPT, a rare genetic disorder associated with high mortality rates, is often caused by inactivating CaSR gene variants. The patient’s family history revealed a strong correlation with familial hypocalciuric hypercalcemia (FHH), a benign condition associated with asymptomatic hypercalcemia, normal to minimally elevated parathyroid level, and hypocalciuria, it is caused by heterozygous inactivating mutations in the CaSR gene. Treatment of NSHPT typically involves total or subtotal parathyroidectomy; however, initial medical intervention is often necessary. In this case, the neonate underwent medical treatment with calcitonin, furosemide to help facilitate renal clearance of calcium, and intravenous fluids before a successful parathyroidectomy. Conclusions: This case accentuates the importance of considering rare genetic disorders in neonates with complex clinical presentations and affirms the need for comprehensive counseling and education, particularly in consanguineous parents, to address familial implications and guide appropriate interventions.

Neurocognitive impairment among children born preterm may arise from complex interactions between genes and the intra-uterine environment. (1) To characterize the transcriptomic profiles of chorioamniotic membranes in preterm neonates with and without neurocognitive impairment via microarrays and (2) to determine if neonates with neurocognitive impairment can be identified at birth. A retrospective case-control study was conducted to examine the chorioamniotic transcriptome of gestational-age matched very preterm neonates with and without neurocognitive impairment at 18-24 months' corrected-age defined by a Bayley-III Cognitive Composite Score <80 (n = 14 each). Pathway analysis with down-weighting of overlapping genes (PADOG) was performed to identify KEGG pathways relevant to the phenotype. Select differentially expressed genes were profiled using qRT-PCR and a multi-gene disease prediction model was developed using linear discriminant analysis. The model's predictive performance was tested on a new set of cases and controls (n = 19 each). 1) 117 genes were differentially expressed among neonates with and without subsequent neurocognitive impairment (p<0.05 and fold change >1.5); 2) Gene ontology analysis indicated enrichment of 19 biological processes and 3 molecular functions; 3)PADOG identified 4 significantly perturbed KEGG pathways: oxidative phosphorylation, Parkinson's disease, Alzheimer's disease and Huntington's disease (q-value <0.1); 4) 48 of 90 selected differentially expressed genes were confirmed by qRT-PCR, including genes implicated in energy metabolism, neuronal signaling, vascular permeability and response to injury (e.g., up-regulation of SEPP1, APOE, DAB2, CD163, CXCL12, VWF; down-regulation of HAND1, OSR1)(p<0.05); and 5) a multi-gene model predicted 18-24 month neurocognitive impairment (using the ratios of OSR1/VWF and HAND1/VWF at birth) in a larger, independent set (sensitivity = 74%, at specificity = 83%). Gene expression patterns in the chorioamniotic membranes link neurocognitive impairment in preterm infants to neurodegenerative disease pathways and might be used to predict neurocognitive impairment. Further prospective studies are needed.

OBJECTIVE: To review our experience of caspofungin in the treatment of persistent candidemia in the neonatal intensive care unit. STUDY DESIGN: This was a retrospective chart review on 13 infants in whom caspofungin was added to conventional antifungals (amphotericin B and/or fluconazole or flucytosine) for the treatment of refractory candidemia. RESULTS: A total of 12 infants were preterm (gestational age, 24 to 28 weeks) and one was term; the median birth weight was 800 g (range, 530 to 5600 g). Candidemia ( Candida albicans in five, C. parapsilosis in six, C. albicans and C. parapsilosis in one and C. tropicalis in one) persisted despite 6 to 30 days of conventional antifungal therapy. After the addition of caspofungin, sterilization of blood cultures was achieved in 11 infants at the median time of 3 days (range, 1 to 21 days). Adverse events included thrombophlebitis (one patient), hypokalemia (two patients) and elevation of liver enzymes (four patients). Three infants had a second episode of candidemia and seven patients died. CONCLUSION: Caspofungin may be an efficacious addition for treatment of candidemia refractory to conventional antifungal therapy. This drug should be further investigated in neonates.

Neonatal aortic thrombus is a rare and critical condition that can present mimicking severe coarctation of the aorta or interrupted aortic arch. Transcatheter thrombectomy for this lesion has not been well described. We report a premature neonate with an occlusive proximal descending aorta thrombus, who underwent transcatheter mechanical thrombectomy using an Amplatzer Piccolo PDA occluder (Abbott, North Chicago, IL, USA). The procedure was successful with no subsequent distal thromboembolic events.

BackgroundStudies of early childhood outcomes of mild hypoxic-ischemic encephalopathy (HIE) identified in the first 6 h of life are lacking.ObjectiveTo evaluate neurodevelopmental outcomes at 18–22 months of PRIME study.Study designMulticenter, prospective study of mild HIE defined as ≥1 abnormality using the modified Sarnat within 6 h of birth and not meeting cooling criteria. Primary outcome was disability with mild: Bayley III cognitive 70–84 or ≥85 and either Gross Motor Function Classification System (GMFCS) 1 or 2, seizures, or hearing deficit; moderate: cognitive 70–84 and either GMFCS 2, seizures, or hearing deficit; severe: cognitive <70, GMFCS 3–5.ResultsOf the 63 infants enrolled, 51 (81%) were evaluated at 19 ± 2 months and 43 (68%) completed Bayley III. Of the 43 infants, 7 (16%) were diagnosed with disability, including 1 cerebral palsy and 2 autism. Bayley scores < 85 in either cognition, motor, or language were detected in 17 (40%): 14 (32%) language, 7 (16%) cognitive, and 6 (14%) motor domain. Infants with disability had more abnormalities on discharge examination and brain MRI, with longer hospital stay (p < 0.001).ConclusionsIn this contemporary untreated cohort of mild HIE, disability occurred in 16% of infants at 18–22 months.

This multicenter trial showed no significant differences in the composite outcome of death or neurodevelopmental impairment among extremely preterm infants randomly assigned to early CPAP or early surfactant and to lower or higher oxygen saturation. Extremely premature infants are at high risk for death and neurosensory or developmental impairment in early childhood. 1 – 3 The risk of neurodevelopmental impairment increases with decreasing gestational age and greater severity of illness. Neurodevelopmental impairment is often a consequence of neonatal complications. 4 – 12 Although surfactant administration decreases the risk of death and bronchopulmonary dysplasia, randomized, controlled trials of various respiratory interventions have not shown significant reductions in mortality and morbidity or improvement in developmental outcomes. 13 – 17 We previously reported results of the multicenter, randomized, controlled Surfactant, Positive Pressure, and Pulse Oximetry Randomized Trial (SUPPORT), which involved extremely premature infants (from . . .

ObjectiveTo evaluate the association between sedation–analgesia (SA) during initial 72 h and death/disability at 18 months of age in neonatal hypoxic-ischemic encephalopathy (HIE).DesignThis was a secondary analysis of the NICHD therapeutic hypothermia (TH) randomized controlled trial in moderate or severe HIE. Receipt of SA and anticonvulsant medications at five time points were considered: prior to and at baseline, 24, 48, and 72 h of TH or normothermia. Disability was defined as mental developmental index <85, cerebral palsy, blindness, hearing impairment, or Gross Motor Function Classification System 2–5.ResultsOf the 208 RCT participants, 38 (18%) infants had no exposure to SA or anticonvulsants at any of the five time points, 20 (10%) received SA agents only, 81 (39%) received anticonvulsants only, and 69 (33%) received both SA and anticonvulsants. SA category drugs were not administered in 57% of infants while 18% received SA at ≥3 time points; 72% infants received anticonvulsants during 72 h of intervention. At 18 months of age, disability among survivors and death/disability was more frequent in the groups receiving anticonvulsants, with (48 and 65%) or without (37 and 58%) SA, compared to groups with no exposure (14 and 34%) or SA (13 and 32%) alone. Severe HIE (aOR 3.60; 1.59–8.13), anticonvulsant receipt (aOR 2.48; 1.05–5.88), and mechanical ventilation (aOR 7.36; 3.15–17.20) were independently associated with 18-month death/disability, whereas TH (aOR 0.28; 0.13–0.60) was protective. SA exposure showed no association with outcome.ConclusionsThe risk benefits of SA in HIE need further investigation.
