RESUMO
PURPOSE: Historically, the presence of gray matter heterotopia was a concern for adverse postnatal neurocognitive status in patients undergoing fetal closure of open spinal dysraphism. The purpose of this study was to evaluate neurodevelopmental outcomes and the onset of seizures during early childhood in patients with a prenatal diagnosis of myelomeningocele/myeloschisis (MMC) and periventricular nodular heterotopia (PVNH). METHODS: All patients evaluated at the Center for Fetal Diagnosis and Treatment with a diagnosis of MMC between June 2016 to March 2023 were identified. PVNH was determined from prenatal and/or postnatal MRI. The Bayley Scales of Infant and Toddler Development (edition III or IV) were used for neurodevelopmental assessments. Patients were screened for seizures/epilepsy. RESULTS: Of 497 patients evaluated with a prenatal diagnosis of MMC, 99 were found to have PVNH on prenatal MRI, of which 35 had confirmed PVNH on postnatal imaging. From the 497 patients, 398 initially did not exhibit heterotopia on prenatal MRI, but 47 of these then had confirmed postnatal PVNH. The presence of PVNH was not a significant risk factor for postnatal seizures in early childhood. The average neurodevelopmental scores were not significantly different among heterotopia groups for cognitive, language, and motor domains. CONCLUSION: The presence of PVNH in patients with a prenatal diagnosis of MMC does not indicate an increased risk for neurodevelopmental delay at 1 year of age. We did not demonstrate an association with seizures/epilepsy. These findings can aid clinicians in prenatal consultation regarding fetal repair of open spinal dysraphism. Long-term follow-up is required to discern the true association between PVNH seen on prenatal imaging and postnatal seizures/epilepsy and neurodevelopmental outcomes.

OBJECTIVE: To describe our experience with treprostinil, evaluate correlations with cardiac function, and assess for adverse effects in neonates with congenital diaphragmatic hernia-related pulmonary hypertension (CDH-PH). STUDY DESIGN: A retrospective review of a single-center prospective registry at a quaternary care children's hospital. Patients included in the study had CDH-PH treated with treprostinil between April 2013 and September 2021. Assessed outcomes were brain-type natriuretic peptide levels and quantitative echocardiographic parameters collected at baseline, 1 week, 2 weeks, and 1 month after treprostinil initiation. Right ventricular (RV) function was assessed by tricuspid annular plane systolic excursion Z-score and speckle tracking echocardiography (global longitudinal and free wall strain). Septal position and left ventricular (LV) compression were assessed by eccentricity index and M-mode Z-scores. RESULTS: Fifty-one patients were included, with an average expected/observed lung-to-head ratio of 28.4 ± 9.0%. Most patients required extra-corporeal membrane oxygenation (n = 45, 88%). Survival to hospital discharge was 31/49 (63%). Treprostinil was initiated at a median age of 19 days with a median effective dose of 34 ng/kg/minute. Median baseline brain-type natriuretic peptide level decreased from 416.9 pg/mL to 120.5 pg/mL after 1 month. Treprostinil was associated with improved tricuspid annular plane systolic excursion Z-score, RV global longitudinal strain, RV free wall strain, LV eccentricity index, and LV diastolic and systolic dimensions, reflecting less compression by the RV, regardless of ultimate patient survival. No serious adverse effects were recorded. CONCLUSIONS: In neonates with CDH-PH, treprostinil administration is well tolerated and is associated with improved RV size and function.

BACKGROUND: We evaluated the impact of delivery at a comprehensive fetal care center co-located in a pediatric hospital on extracorporeal membrane oxygenation (ECMO) exposure and survivorship of children with CDH. METHODS: This retrospective study includes maternal-fetal dyads with a prenatal diagnosis of isolated CDH who received any prenatal care at a single fetal center between February 2006 and March 2021. The principal variables included: (1) delivery setting (children born in the pediatric hospital ["inborn"] vs. children who were delivered elsewhere ["outborn"]), (2) exposure to ECMO (yes vs. no), and (3) survival-at-discharge from birth hospitalization (yes vs. no). Multivariable logistic regression was used to evaluate the association between delivery setting and ECMO cannulation, and whether delivery setting moderates the association between exposure to ECMO and survival-at-discharge. RESULTS: Among 418 maternal-fetal dyads, 77.0% of children were inborn and 32.0% of children were exposed to ECMO during their index hospitalization. Inborn children had more severe prenatal prognostic indicators but had a 57% lower odds of extracorporeal than outborn children. In multivariable logistic regression, delivery setting moderated the association between exposure to ECMO and survival-at-discharge. Although there was no statistically significant difference in mortality between inborn and outborn children who were not exposed to ECMO, inborn children exposed to ECMO had a 6.86 (1.98, 23.74) increased odds of death and outborn children exposed to ECMO had a 17.71 (4.69, 66.87) increased odds of death when both were compared to non-cannulated outborn children. CONCLUSIONS: Comprehensive fetal care with delivery co-located in a pediatric hospital was associated with decreased exposure to ECMO and a survivorship advantage among children with CDH who required extracorporeal support. LEVEL OF EVIDENCE: Level III.

BACKGROUND: Executive function, adaptive function, and behavioral outcomes in congenital diaphragmatic hernia (CDH) survivors have not been well studied. AIM: To evaluate executive and neurobehavioral dysfunction in preschool and early school-aged children with CDH. STUDY DESIGN: Retrospective cohort study. SUBJECTS: All eligible CDH survivors ages 3 to 7 years enrolled in our follow-up program between February 2020 and February 2021. OUTCOME MEASURES: The Behavior Rating Inventory of Executive Function (BRIEF), the Adaptive Behavior Assessment System, 2nd Edition (ABAS-II), and the Child Behavior Checklist (CBCL) were used to assess functional and behavioral outcomes. Summary scores were compared to standard population norms. RESULTS: A total of 100 patients were enrolled during the study period. Of those, 73 parents completed at least one of the questionnaires, resulting in completion of the BRIEF, ABAS-II, and CBCL for 63, 68, and 63 patients, respectively. Preschool children had normal executive function (BRIEF-P) while global executive composite (P = 0.012) and the emotional regulation index (P = 0.010) for school age patients (BRIEF-2) were worse. CDH survivors had favorable adaptive functioning (ABAS-II). Mean CBCL scores for preschool attention problems (P = 0.018), school age attention problems (P = 0.001), and attention deficits hyperactivity problems (P = 0.027) were significantly worse. Prematurity, surrogate markers of disease severity, non-white race, and public insurance status were associated with worse neurobehavioral dysfunction in bivariable analysis. CONCLUSIONS: The majority of preschool and school age CDH survivors have age-appropriate executive, adaptive and behavioral functioning. CDH survivors, however, have lower executive function and attention scores compared with the general population.

BACKGROUND: The objective of this study was to identify factors associated with prolonged birth admission length of stay (LOS) and to evaluate the association between these characteristics and readmission in the year following discharge for children with congenital diaphragmatic hernia (CDH). METHODS: This was a single-center retrospective cohort study of children with isolated CDH born in the Special Delivery Unit and admitted to the Newborn/Infant Intensive Care Unit at Children's Hospital of Philadelphia from April 2008 to August 2019. Birth admission hospitalization was categorized into 3 groups (≤35, 36-75, and >76 days) based on the data distribution. Participant factors included gestational age (days), side of CDH (right/left), liver position (up/down), CDH repair technique (open/minimally invasive), exposure to extracorporeal membrane oxygenation, lung-to-head circumference ratio, and feeding tube at discharge. Chi-squared, t-tests and analysis of variance were used to examine bivariable associations between participant characteristics, birth admission LOS and readmission in the year following initial hospital discharge. Multivariable logistic regression was used to evaluate factors associated with readmission. RESULTS: Children hospitalized ≥76 days at birth had 4.33 (95% CI: 1.2, 15.2) higher odds of readmission than those admitted for ≤35 days. Children with a non-operative feeding tube at discharge had 4.12 (895% CI: 1.6, 10.5) higher odds of readmission when compared to those with no feeding tube at discharge. CONCLUSIONS: Longer birth hospitalization and non-operative feeding tube are associated with increased readmissions in the year after discharge. LEVEL OF EVIDENCE: Level III.
