RESUMEN
The long-term neurodevelopment of children born with oesophageal atresia (OA) is unclear. Therefore, we assessed the neurocognitive domains and their predictors. Patients born with OA between February 2006 and December 2014, who were routinely seen at eight years as part of a structured prospective longitudinal follow-up program, were included. Main outcome measures were need for school support, performance in various neurocognitive domains and potential predictors of neurocognitive problems. We analysed data of 65 children with a mean (SD) age of 8.1 (0.2) years, of whom 89% with OA type C. Thirty-five (54%) surgical corrections were minimally invasive; the median (interquartile range) duration of exposure to anaesthetics in the first 24 months was 398 (296 - 710) minutes. Forty-four (68%) attended regular education without extra support and intelligence was within normal range (99-108). More than 50% had z-scores ≤ -2 on one or more neurocognitive domains, of which attention was the most frequently affected domain. The speed on the sustained attention task was significantly below normal (z-score -1.48 (2.12), p < .001), as was fluctuation of sustained attention (z-score -3.19 (3.80), p < .001). The minimally invasive approach and a lower socio-economic status (both p = 0.006) proved significant predictors for sustained attention problems in multivariable analyses. Conclusion: Children who undergo minimally invasive surgery for OA correction are at risk for sustained attention problems at school age. Future studies unravelling the effects of perioperative events on neurodevelopment should lead to optimal surgical, anaesthesiological, and intensive care management in the neonatal period. What is Known: ⢠School-aged children born with oesophageal atresia have normal intelligence but problems with sustained attention at eight years. What is New: ⢠Oesophageal atresia patients, who undergo minimally invasive surgery or who have a background of lower socioeconomic status are at serious risk for sustained attention problems at school age. ⢠Moreover, those who have been intubated for a longer period are at risk for stronger fluctuations in sustained attention.

BACKGROUND: Congenital diaphragmatic hernia (CDH) is a rare birth defect with substantial mortality. This study aims to generate a population-based overview of CDH care and outcomes in the Netherlands. Moreover, it assesses interhospital variations between the two Dutch CDH expert centres. METHODS: This study uses data from the Dutch branch of the European Pediatric Surgical Audit, a prospective clinical audit for congenital anomalies. Data of all patients with CDH treated between 2014 and 2021 were included for epidemiological analysis. For comparative analyses, patients presenting after the neonatal period or not treated in the two CDH expert centres were excluded. Identified interhospital variations were assessed using regression analysis. RESULTS: In the study period, 283 children with CDH were born, resulting in a national prevalence rate of 2.06/10 000 live births. The patient population, treatment and outcomes at 1 year were comparable between the hospitals, except for length of hospital stay. Regression analysis identified the treating hospital as the strongest significant predictor thereof. Other factors associated with longer length of stay include the presence of other malformations, intrathoracic liver position on prenatal ultrasound, extracorporeal membrane oxygenation treatment, patch repair, complicated postoperative course and discharge to home rather than to another care facility. CONCLUSION: Outcomes of CDH care throughout the Netherlands are comparable. However, the length of stay differed between the two hospitals, also when adjusting for other covariates. Further qualitative analysis to explain this interhospital variation is indicated. Our findings underscore the potential of clinical auditing as a quality measurement tool in rare conditions.

BACKGROUND: Oesophageal atresia (OA) is often accompanied by tracheomalacia (TM). The aim of this study was to evaluate its presence in OA patients during routine rigid tracheobronchoscopy (TBS) before primary correction and compare this to postoperative TBS and clinical signs of TM. METHODS: This retrospective cohort study included patients born with OA between June 2013 and December 2022 who had received a TBS before OA correction and had been followed for at least twelve months. Definite TM was postoperatively diagnosed through TBS, and probable TM was defined as having symptoms of TM. RESULTS: We analysed data from 79 patients, of whom 87% with OA type C. Preoperatively, TM was observed in 33 patients (42% of all patients), seven of whom had severe TM. Definite TM was observed in 21 patients (27%), of whom 15 had severe TM. Forty-one patients (52% of all patients) had developed symptoms of TM within twelve months, including harsh barking cough (n = 15), stridor and/or wheezing (n = 20), recurrent respiratory insufficiency (n = 11), or needing airway surgery (n = 7). The sensitivity of preoperative TBS for the presence of postoperative (definite and probable combined) TM is 50.0%, 95% CI [35.2-64.8], and the specificity 67.6%, 95% CI [51.7-81.1]. Clinical characteristics did not differ between the patients with or without postoperative TM. CONCLUSIONS: More than half of the studied patients with OA experienced symptoms of TM. While preoperative TBS is routinely performed prior to surgical OA correction, its predictive value for the presence of postoperative TM remains limited. LEVEL OF EVIDENCE: Level II. TYPE OF STUDY: Study of Diagnostics Test.
RESUMEN
OBJECTIVE: The clinical implications of a postnatal chest X-ray (CXR) in asymptomatic children with a prenatally diagnosed congenital lung malformation (CLM) are uncertain. We assessed the justification for the postnatal use of CXR in these children. METHODS: We included patients with CLM confirmed through chest computed tomography angiography or histopathological analysis who were asymptomatic at birth, underwent routine postnatal CXR, and participated in our standard of care prospective structured longitudinal follow-up program. Children with major associated morbidities were excluded. Primary outcomes were the positive and negative predictive values (PPV and NPV) of CXR findings for symptom development at 4 weeks and 6 months of age. Secondarily, we sought to establish whether CXR findings were associated with undergoing additional diagnostics during the initial observational hospital stay or prolonged postnatal hospital admission. RESULTS: Among 121 included patients, CXR showed no abnormalities in 35 (29%), nonspecific abnormalities in 23 (19%), and probable CLM in 63 (52%). The PPV of CXR in relation to symptom development at 4 weeks and 6 months was 0.05 and 0.25, respectively. Corresponding NPVs were 0.96 and 0.91. An association was identified between CXR findings and undergoing further diagnostics during the initial observational hospital stay (p = .047). Additional diagnostic findings did not influence clinical management. CXR findings were not associated with prolonged initial hospital stay (p = .40). CONCLUSION: The routine practice of postnatal CXR in asymptomatic patients with prenatally diagnosed CLM can be omitted, as CXR findings do not influence subsequent clinical management.
RESUMEN
BACKGROUND: Gastroesophageal reflux disease (GERD) is a common comorbidity associated with congenital diaphragmatic hernia (CDH), with reported cases of Barrett's esophagus (BE) and esophageal adenocarcinoma before the age of 25. The prevalence and natural course of GERD in CDH survivors remain uncertain due to variations in diagnostic methods. We aimed to analyse the GERD prevalence from infancy through young adulthood. METHODS: We retrospectively analyzed pH-impedance measurements and endoscopic findings in 96 CDH survivors evaluated as routine care using well established clinical protocols. GERD was defined as an abnormal acid exposure time for pH-MII measurements and as presence of reflux esophagitis or BE at upper endoscopy. Clinical data including symptoms at time of follow-up and use of antireflux medication were collected. RESULTS: GERD prevalence remained consistently low (≤10%) across all age groups, yet many patients experienced GER symptoms. Histological abnormalities were observed in 80% of adolescents and young adults, including microscopic esophagitis in 50%. BE was diagnosed in 7% before the age of 18, all had GER symptoms. CDH severity, anatomy at the time of CDH correction, alcohol usage, and smoking did not emerge as significant risk factors for GERD. CONCLUSIONS: Given the low GERD prevalence in CDH survivors, a symptom-driven approach to diagnosis and follow-up is warranted. We advise long-term follow-up for all adult patients due to the early onset of BE and the limited evidence available. The longitudinal course and impact of GERD on other long-term CDH-related comorbidities should be explored in larger cohorts. LEVEL OF EVIDENCE: Not applicable.
RESUMEN
BACKGROUND: Infants born with congenital diaphragmatic hernia (CDH) are at high risk of respiratory insufficiency and pulmonary hypertension. Routine practice includes immediate clamping of the umbilical cord and endotracheal intubation. Experimental animal studies suggest that clamping the umbilical cord guided by physiological changes and after the lungs have been aerated, named physiological-based cord clamping (PBCC), could enhance the fetal-to-neonatal transition in CDH. We describe the statistical analysis plan for the clinical trial evaluating the effects of PBCC versus immediate cord clamping on pulmonary hypertension in infants with CDH (PinC trial). DESIGN: The PinC trial is a multicentre, randomised controlled trial in infants with isolated left-sided CDH, born ≥ 35.0 weeks of gestation. The primary outcome is the incidence of pulmonary hypertension in the first 24 h after birth. Maternal outcomes include estimated maternal blood loss. Neonatal secondary outcomes include mortality before discharge, extracorporeal membrane oxygenation therapy, and number of days of mechanical ventilation. Infants are 1:1 randomised to either PBCC or immediate cord clamping using variable random permutated block sizes (4-8), stratified by treatment centre and estimated severity of pulmonary hypoplasia (i.e. mild/moderate/severe). At least 140 infants are needed to detect a relative reduction in pulmonary hypertension by one third, with 80% power and 0.05 significance level. A chi-square test will be used to evaluate the hypothesis that PBCC decreases the occurrence of pulmonary hypertension. This plan is written and submitted without knowledge of the collected data. The trial has been ethically approved. TRIAL REGISTRATION: ClinicalTrials.gov NCT04373902 (registered April 2020).

Introduction: The growing population of survivors following pediatric surgery emphasizes the importance of long-term follow-up. The impact of surgical scars on daily life can be evaluated through patient-reported outcome measurements. The Stony Brook Scar Evaluation Scale (SBSES) and SCAR-Q questionnaire are two interesting instruments for this purpose. We evaluated their psychometric performance in Dutch children after pediatric surgery. Methods: After English-Dutch translation, we evaluated-following the COSMIN guidelines-the feasibility, reliability (internal and external), and validity (construct, criterion, and convergent) of the SBSES and SCAR-Q in Dutch patients < 18 years old with surgical scars. Results: Three independent observers completed the SB for 100 children (58% boys, median age 7.3 (IQR 2.5-12.1) years) in whom surgery had been performed a median of 2.8 (0.5-7.9) years ago. Forty-six of these children (61% boys, median age 12.1 (9.3-16.2) years) completed the SCAR-Q. Feasibility and internal reliability (Cronbach's alpha > 0.7) was good for both instruments. For the SB, external reliability was poor to moderate (interobserver variability: ICC 0.46-0.56; intraobserver variability: ICC 0.74). For the SCAR-Q, external reliability was good (test-retest agreement: ICC 0.79-0.93). Validity tests (construct, criterion, and convergent) showed poor to moderate results for both instruments. Conclusions: The Dutch-translated SBSES and SCAR-Q showed good feasibility and internal reliability. External reliability and validity were likely affected by differences in conceptual content between the questionnaires. Combining them would provide insight in the impact of scars on patients. Implementation of these instruments in longitudinal follow-up programs could provide new insights into the long-term psychological outcome after pediatric surgery.

Currently there is a global lack of consensus about the best treatment for asymptomatic congenital pulmonary airway malformation (CPAM) patients. The somatic KRAS mutations commonly found in adult lung cancer combined with mucinous proliferations are sometimes found in CPAM. For this risk of developing malignancy, 70% of paediatric surgeons perform a resection for asymptomatic CPAM. In order to stratify these patients into high- and low-risk groups for developing malignancy, a minimally invasive diagnostic method is needed, for example targeted molecular imaging. A prerequisite for this technique is a cell membrane bound target. The aim of this study was to review the literature to identify potential targets for molecular imaging in CPAM patients and perform a first step to validate these findings.A systematic search was conducted to identify possible targets in CPAM and adenocarcinoma in situ (AIS) patients. The most interesting targets were evaluated with immunofluorescent staining in adjacent lung tissue, KRAS+ CPAM tissue and KRAS- CPAM tissue.In 185 included studies, 143 possible targets were described, of which 20 targets were upregulated and membrane-bound. Six of them were also upregulated in lung AIS tissue (CEACAM5, E-cadherin, EGFR, ERBB2, ITGA2 and MUC1) and as such of possible interest. Validating studies showed that MUC1 is a potential interesting target.This study provides an extensive overview of all known potential targets in CPAM that might identify those patients at risk for malignancy and conducted the first step towards validation, identifying MUC1 as the most promising target.
