Objective Efforts directed at mitigating neurological disability in preterm infants with intraventricular hemorrhage (IVH) and post hemorrhagic hydrocephalus (PHH) are limited by a dearth of quantifiable metrics capable of predicting long-term outcome. The objective of this study was to examine the relationships between candidate cerebrospinal fluid (CSF) biomarkers of PHH and neurodevelopmental outcomes in infants undergoing neurosurgical treatment for PHH. Study design Preterm infants with PHH were enrolled across the Hydrocephalus Clinical Research Network. CSF samples were collected at the time of temporizing neurosurgical procedure (n = 98). Amyloid precursor protein (APP), L1CAM, NCAM-1, and total protein (TP) were compared in PHH versus control CSF. Fifty-four of these PHH subjects underwent Bayley Scales of Infant Development-III (Bayley-III) testing at 15–30 months corrected age. Controlling for false discovery rate (FDR) and adjusting for post-menstrual age (PMA) and IVH grade, Pearson’s partial correlation coefficients were used to examine relationships between CSF proteins and Bayley-III composite cognitive, language, and motor scores. Results CSF APP, L1CAM, NCAM-1, and TP were elevated in PHH over control at temporizing surgery. CSF NCAM-1 was associated with Bayley-III motor score (R = -0.422, p = 0.007, FDR Q = 0.089), with modest relationships noted with cognition (R = -0.335, p = 0.030, FDR Q = 0.182) and language (R = -0.314, p = 0.048, FDR Q = 0.194) scores. No relationships were observed between CSF APP, L1CAM, or TP and Bayley-III scores. FOHR at the time of temporization did not correlate with Bayley-III scores, though trends were observed with Bayley-III motor (p = 0.0647 and R = -0.2912) and cognitive scores (p = 0.0506 and R = -0.2966). Conclusion CSF NCAM-1 was associated with neurodevelopment in this multi-institutional PHH cohort. This is the first report relating a specific CSF protein, NCAM-1, to neurodevelopment in PHH. Future work will further investigate a possible role for NCAM-1 as a biomarker of PHH-associated neurological disability.

Abstract Background Compared with those born at term gestation, infants with complex congenital heart defects (CCHD) who were delivered before 37 weeks of gestational age and received neonatal open cardiac surgery (OHS) have poorer neurodevelopmental outcomes in early childhood. Specific details related to the neurodevelopmental outcome of these infants remain unpublished. Objectives To describe the growth, disability, functional, and neurodevelopmental outcome in early childhood of preterm infants (born at &lt;37+0 weeks gestation) with CCHD and neonatal OHS. Design/Methods We studied all infants with CCHD who received OHS within 6 weeks of corrected age between 1996 and 2016. In the Western Canadian Complex Pediatric Therapies Follow-up Program, comprehensive neurodevelopmental assessments at a corrected age of 18-24 months were done by multidisciplinary teams at the original referral sites. In addition to demographic and clinical data, standardized age-appropriate outcome measures included physical growth with calculated Z-scores, disabilities including cerebral palsy, visual impairment, sensorineural hearing loss; adaptive function (Adaptive Behavioural Assessment System-II); and cognitive, language, and motor skills (Bayley Scales of Infant and Toddler Development-III). Results From 1996 to 2016, 115 preterm infants (34±2 weeks gestation, 2339±637g, 64% males) with CCHD had OHS with 11(10%) deaths before first discharge and 21 (18%) by 2 years. Prior to the first surgery, 7 (6%) neonates had cerebral injuries. Overall, 7 had necrotizing enterocolitis; none had retinopathy of prematurity. All 94 surviving infants received comprehensive evaluation at 2 years corrected age; Eighteen (19%) had congenital syndromes who had worse functional and neurodevelopmental outcomes compared to those (n=76) without syndromal abnormalities (SA) (Table). Conclusion For preterm neonates with CCHD and early OHS, the mortality was significant, but the short-term neonatal morbidity was not increased. Compared with published preterm outcomes, the early outcome suggests more cerebral palsy but not sensorineural hearing loss, and greater neurodevelopmental delay. This information is important for management care of the infants, parental counselling and the decision-making process.

Abstract Objective This study aimed to compare neurodevelopmental outcomes in preterm infants at 18 to 26 months corrected age (CA) who did versus did not achieve full oral feedings at 40 weeks postmenstrual age (PMA). Study Design This retrospective study included infants born between 2010 and 2015 with gestational age <32 weeks and followed between 18 and 26 months CA. Achievement of full oral feedings was defined as oral intake >130 mL/kg/d for >72 hours by 40 weeks PMA. Incidence of cognitive, language, or motor delay, or cerebral palsy at 18 to 26 months CA was compared in multivariable analyses for infants in the two feeding groups. Results Of 372 included infants, those achieving full oral feedings had lower incidence of any adverse neurodevelopmental outcome (p < 0.001) compared with those who did not achieve full oral feedings. In multivariable analyses, achievement of full oral feedings by 40 weeks PMA was associated with decreased odds of cognitive, language, and motor delays, cerebral palsy, and any adverse neurodevelopmental outcome at follow-up. Conclusion Achievement of full oral feedings by 40 weeks PMA was associated with better adjusted neurodevelopmental outcomes at 18 to 26 months CA. Inability to fully feed orally at 40 weeks PMA may be a simple, clinically useful marker for risk of adverse neurodevelopmental outcomes.

Abstract Background For several decades, transient hypothyroxinemia of prematurity (THOP) has been a topic of debate. The pathophysiology is incompletely understood and consensus on the therapeutic approach is lacking. This study aimed at gaining a better insight into the pathogenesis by studying the trends in thyroid hormone (TH) levels during the first week of life. Methods This single-center prospective observational study analyzed the plasma levels of total thyroxine (T4) and free thyroxine (fT4), total triiodothyronine (T3), thyroid-stimulating hormone (TSH) and T4-binding globulin (TBG) in cord blood and at the end of the first week of life in 120 preterm infants (gestational age [GA] <37 weeks). The change over time was calculated (delta, ∆). The impact of perinatal and subsequently postnatal variables on ∆ was studied by hierarchical multiple regression. The impact of ∆ on the neurodevelopmental outcome at the corrected ages of 9 and 24 months, measured by the Bayley Scales of Infant Development (BSID)-II, was assessed by logistic regression. Results ∆fT4 levels were negatively affected by GA and use of dopamine, whereas only GA was associated with low ∆T3 levels. Negative ∆fT4 levels were present in 75% of the extremely low-for-gestational-age infants, whereas 23.5% had a negative ∆T3 level. There was an increased risk for an abnormal mental developmental score (<85) with decreasing ∆T3 at 9 months, corrected age, but not at 24 months. Conclusions A negative evolution in circulating TH levels is principally an immaturity phenomenon, whereas dopamine can further suppress the hypothalamic-pituitary-thyroid axis. There is at least a temporary negative effect of this evolution on the infants’ neurodevelopment.

Thoracoscopic Repair

Introduction Multiple reports have questioned the feasibility of neonatal thoracoscopic repair of congenital diaphragmatic hernia (CDH) and esophageal atresia (EA). The aim of this study is to examine the effects of CO2 pneumothorax on cerebral and renal rSO2 and to assess the potential predictive value of these data on neurodevelopmental outcome after neonatal thoracoscopic surgery for CDH or EA. Materials and Methods A prospective observational pilot study. Cerebral and renal regional tissue oxyhemoglobine saturation (rSO2) rSO2 were assessed using near-infrared spectroscopy (NIRS) during thoracoscopic surgery in neonates with CDH and with EA, in addition to routine anesthesia monitoring. Cerebral and renal rSO2, linked to repeated arterial blood gas analyses, heart rate, blood pressure, and to structured longitudinal neurodevelopmental follow-up. Results Baseline estimated marginal means of cerebral rSO2 values (CDH: 82%, EA: 91%) did not change significantly during pneumothorax (CDH: 81%, EA 79% [n.s. versus baseline]) despite severe acidosis (lowest pH, CDH: 6.99, EA: 7.1). Neurodevelopmental outcomes at 24 months were normal in all 7 patients who were available for evaluation. Conclusion Neonatal thoracoscopic repair of CDH and EA using CO2-pneumothorax leads to severe acidosis. Cerebral rSO2 remained within clinical acceptable limits during intraoperative periods of acidosis. Neurodevelopmental outcome was favorable within the first 24 months. The potential of NIRS to further improve perioperative care and long-term outcome in this specific patient group deserves further investigation.

Abstract BACKGROUND Bronchopulmonary dysplasia (BPD) is a known risk factor for neurodevelopmental impairment in preterm infants. BPD is also associated with an increased incidence of high systemic blood pressure (HBP). However, it is not known if a diagnosis of HBP in BPD patients relates to later neurodevelopmental outcomes. OBJECTIVES We aimed to determine the incidence of neonatal HBP diagnosis in a cohort of preterm infants born <29 weeks of gestational age (GA) with BPD. The secondary objective was to assess if a concomitant diagnosis of BPD and HBP influences neurodevelopmental outcomes at 18 months. DESIGN/METHODS We performed a single center retrospective study using data from medical charts. All infants born <29 weeks GA admitted to our level-IV neonatal intensive care unit between January 2010 and December 2012 diagnosed with BPD at 36 weeks of corrected GA were included. Patients transferred before 36 weeks of corrected GA, that died before 18 months or had congenital anomalies were excluded. Patients were classified in the HBP group if HBP was a documented diagnosis in the chart. The control group was the remaining patients with BPD at 36 weeks corrected GA but without HBP. Severe neurodevelopmental impairment at 18 months was defined as either any Bailey-III score <70, cerebral palsy or severe hearing or visual impairment. Descriptive statistics for prenatal and postnatal patients’ characteristics were analyzed. Logistic regression was performed for factors associated with long-term disability. Level of significance was determined as a p value <0.05. RESULTS During the study period, 337 preterm infants <29 weeks of GA were identified and after exclusions, 98 newborns met the criteria of BPD at 36 weeks corrected GA. Mean GA and mean birth weight were 26.7 ± 1.7 weeks and 882 ± 199 g respectively. The majority were males (57%) and received antenatal steroids (87.8%). We identified twenty-five newborns (25.5%) with a diagnosis of HBP. Demographic data was similar between the 2 groups. 56% of the HBP group received a post-natal course of steroids, compared to 36% for the control group (p 0.07). The neurodevelopmental outcome at 18 months was similar between the two groups (p 0.54) and was not influenced by the presence of a HBP diagnosis after regression analysis (p 0.8). CONCLUSION The diagnosis of HBP was frequent in our cohort of preterm infants born <29 weeks GA with BPD but did not seem to be related to long-term neurodevelopmental outcomes.

At 1 year we assessed the neurodevelopmental outcomes in infants undergoing cardiac surgery, seeking to explore the predictive value of perioperative markers of cerebral injury. We prospectively enroled 47 neurodevelopmentally normal infants prior to planned cardiac surgery. Postoperative monitoring consisted of 10-channel video synchronised, continuous electroencephalography from 6 to 30 h, Doppler assessment of cerebral blood flow in the anterior cerebral artery at 1, 2, 3 and 5 h, and measurement of serum S-100B at 0 and 24 h. Neurodevelopmental assessments were performed using the second edition of the Bayley Scale of Infant Development. Follow-up at 1 year was available on 35 infants. The mean age of these patients at surgery had been 57 ± 15 days. We observed clinical seizures in 1 patient, with 3 other patients having electroencephalographic abnormalities. At follow-up of 1 year, neurodevelopmental scores were lower than preoperative scores, with mean mental scores changing from 103 ± 5 to 94 ± 13 (p = 0.001), and mean motor scores changing from 99 ± 8 to 89 ± 20 (p = 0.004). No association was found between electroencephalographic abnormalities, reduced cerebral blood flow, or elevation of serum S-100B levels and impaired neurodevelopmental outcome at 1 year. Infants with electroencephalographic abnormalities had elevation of the levels of S-100B in the serum (p = 0.02). At 1 year of follow-up, infants undergoing cardiac surgery demonstrated a reduction in the scores achieved using the second edition of the Bayley Scale of Infant Development. They require ongoing assessment of their progress. Electroencephalographic abnormalities, cerebral blood flow, or levels of S-100B in the serum were not useful perioperative markers for predicting a poor neurodevelopmental outcome in the clinical setting.

Abstract Background: To investigate postnatal growth patterns and their relationship with neurodevelopment in preterm infants born small for gestational age (SGA).Methods: This study analyzed 90 infants born SGA with birth weight <1,500 g or gestational age <32 weeks. Length, weight, and head circumference (HC) were recorded at birth, 35 weeks postmenstrual age (PMA), 40 weeks PMA, and at 4, 9, and 18 months corrected age (CA). Neurodevelopmental outcomes were assessed using the Bayley-III scales at 18 months CA. Results: Z-score of HC in SGA infants increased from birth to 40 weeks PMA. Failure of head growth catch-up to 10th percentile by 4 months CA and all three parameters by 9 months CA and onwards were associated with worse neurodevelopmental outcomes. Z-score changes in head growth between birth and 35 weeks PMA were significantly associated with neurodevelopmental outcome (p=0.006, adjusted odds ratio 6.964, 95% confidence interval: 1.763-27.506). Conclusions: Head growth during neonatal intensive care unit stay were associated with neurodevelopmental outcomes in preterm SGA infants. Preterm SGA infants are predicted to have optimal neurodevelopment at 18 months CA, if the head growth catch-up is achieved by 4 months CA and length and weight by 9 months CA.
