Background Increased risk of scoliosis and musculoskeletal abnormalities in adolescents with esophageal atresia (EA) is reported, but the impact of these abnormalities on physical fitness and motor skills are not known. Methods Scoliosis was assessed radiographically and shoulder and chest abnormalities by a standardized protocol. Physical fitness was evaluated with Grippit, Six-minute walk test, and International Physical Activity Questionnaire and motor skills by Motor Assessment Battery for Children. Results Sixty-seven EA adolescents median 16 (13–20) years participated. The prevalence of significant scoliosis (≥ 20º) was 12% (8/67) whereas 22% (15/67) had mild scoliosis (10–19º). Vertebral anomalies occurred in 18/67 (27%), eight of them (44%) had scoliosis. The majority of adolescents (15/23) with scoliosis did not have vertebral anomalies. Musculoskeletal abnormalities were detected in 22–78%. Balance problems occurred three times more frequently than expected (44% vs. 15%, p = 0.004). Submaximal exercise capacity was significantly reduced compared to reference values (p < 0.001). Scoliosis ≥ 20º was related to reduced physical activity (p = 0.008), and musculoskeletal abnormalities to reduced physical activity and impaired motor skills (p = 0.042 and p < 0.038, respectively). Conclusions Significant scoliosis was diagnosed in 12% of the EA adolescents and related to reduced physical activity. Musculoskeletal abnormalities identified in more than half of the patients, were related to reduced physical activity and impaired motor skills, and exercise capacity was significantly below reference group. EA patients with and without vertebral anomalies need health-promoting guidance to prevent impaired motor skills and consequences of reduced physical activity.

OBJECTIVES To longitudinally evaluate self-reported health status (HS) and quality of life (QoL) in 8- and 12-year-old survivors of congenital diaphragmatic hernia (CDH). We hypothesized that HS would improve with age—as associated health problems tend to decline—whereas QoL would decrease, as the children start to compare themselves with peers. METHODS Self-reported HS and QoL of 133 children born between 1999 and 2013 who had joined our standardized follow-up program were routinely assessed at the ages of 8 and 12 with generic, internationally validated, standardized instruments. Longitudinal evaluation of total and subscale scores was performed using general linear model analyses. In addition, we compared these scores to sex- and age-specific normative data. RESULTS Between ages 8 and 12, boys born with CDH perceived a decline in HS (mean difference −7.15, P < .001). Self-reported QoL did not change over time in both boys and girls. At both ages, HS was significantly lower than that of healthy peers (effect size = 0.71, P = .001 for boys, and effect size = 0.69, P = .003 for girls), whereas differences in QoL were small. CONCLUSIONS Children born with CDH are at risk for declining HS between 8 and 12 years, but not QoL, compared with healthy peers. Given that children born with CDH tend to grow into deficits, our findings highlight the need for continued somatic and psychological assessments in adolescent and adult CDH survivors.

The importance of multidisciplinary long-term follow-up for adults born with esophageal atresia (EA) is increasingly recognized. Hence, a valid, condition-specific instrument to measure health-related quality of life (HRQoL) becomes imperative. This study aimed to develop and validate such an instrument for adults with EA. The Specific Quality of life in Esophageal atresia Adults (SQEA) questionnaire was developed through focus group-based item generation, pilot testing, item reduction and a multicenter, nationwide field test to evaluate the feasibility, reliability (internal and retest) and validity (structural, construct, criterion and convergent), in compliance with the consensus-based standards for the selection of health measurement instruments guidelines. After pilot testing (n = 42), items were reduced from 144 to 36 questions. After field testing (n = 447), three items were discarded based on item-response theory results. The final SQEA questionnaire (33 items) forms a unidimensional scale generating an unweighted total score. Feasibility, internal reliability (Cronbach’s alpha 0.94) and test–retest agreement (intra-class coefficient 0.92) were good. Construct validity was discriminative for esophageal replacement (P

Background: Adverse neurological events during extracorporeal membrane oxygenation (ECMO) are common and may be associated with devastating consequences. Close monitoring, early identification and prompt intervention can mitigate early and late neurological morbidity. Neuromonitoring and neurocognitive/neurodevelopmental follow-up are critically important to optimize outcomes in both adults and children. Objective: To assess current practice of neuromonitoring during ECMO and neurocognitive/neurodevelopmental follow-up after ECMO across Europe and to inform the development of neuromonitoring and follow-up guidelines. Methods: The EuroELSO Neurological Monitoring and Outcome Working Group conducted an electronic, web-based, multi-institutional, multinational survey in Europe. Results: Of the 211 European ECMO centres (including non-ELSO centres) identified and approached in 23 countries, 133 (63%) responded. Of these, 43% reported routine neuromonitoring during ECMO for all patients, 35% indicated selective use, and 22% practiced bedside clinical examination alone. The reported neuromonitoring modalities were NIRS ( n = 88, 66.2%), electroencephalography ( n = 52, 39.1%), transcranial Doppler ( n = 38, 28.5%) and brain injury biomarkers ( n = 33, 24.8%). Paediatric centres (67%) reported using cranial ultrasound, though the frequency of monitoring varied widely. Before hospital discharge following ECMO, 50 (37.6%) reported routine neurological assessment and 22 (16.5%) routinely performed neuroimaging with more paediatric centres offering neurological assessment (65%) as compared to adult centres (20%). Only 15 (11.2%) had a structured longitudinal follow-up pathway (defined followup at regular intervals), while 99 (74.4%) had no follow-up programme. The majority ( n = 96, 72.2%) agreed that there should be a longitudinal structured follow-up for ECMO survivors. Conclusions: This survey demonstrated significant variability in the use of different neuromonitoring modalities during and after ECMO. The perceived importance of neuromonitoring and follow-up was noted to be very high with agreement for a longitudinal structured follow-up programme, particularly in paediatric patients. Scientific society endorsed guidelines and minimum standards should be developed to inform local protocols.

IntroductionConsensus is lacking on the optimal management of asymptomatic congenital pulmonary airway malformation (CPAM). For future studies, the CONNECT consortium (the COllaborative Neonatal Network for the first European CPAM Trial)—an international collaboration of specialised caregivers—has established consensus on a core outcome set of outcome parameters concerning respiratory insufficiency, surgical complications, mass effect and multifocal disease. These outcome parameters have been incorporated in the CONNECT trial, a randomised controlled trial which, in order to develop evidence-based practice, aims to compare conservative and surgical management of patients with an asymptomatic CPAM.Methods and analysisChildren are eligible for inclusion after the CPAM diagnosis has been confirmed on postnatal chest CT scan and they remain asymptomatic. On inclusion, children are randomised to receive either conservative or surgical management. Subsequently, children in both groups are enrolled into a standardised, 5-year follow-up programme with three visits, including a repeat chest CT scan at 2.5 years and a standardised exercise tolerance test at 5 years.The primary outcome is exercise tolerance at age 5 years, measured according to the Bruce treadmill protocol. Secondary outcome measures are molecular genetic diagnostics, validated questionnaires—on parental anxiety, quality of life and healthcare consumption—, repeated imaging and pulmonary morbidity during follow-up, as well as surgical complications and histopathology. This trial aims to end the continuous debate surrounding the optimal management of asymptomatic CPAM.Ethics and disseminationThis study is being conducted in accordance with the Declaration of Helsinki. The Medical Ethics Review Board of Erasmus University Medical Centre Rotterdam, The Netherlands, has approved this protocol (MEC-2022–0441). Results will be disseminated through peer-reviewed scientific journals and conference presentations.Trial registration numberNCT05701514.

Aims The study prospectively assessed motor development from infancy to adolescence in patients with esophageal atresia (EA). Methods At one year of age motor performance was evaluated with the Psychomotor Developmental Index (PDI) of the Bayley Scales of Infant Development, Second Edition (BSID-II), and as adolescents reevaluated with Motor Assessment Battery for Children, Second Edition (MABC-2). Associations to clinical factors were assessed. Results 23 EA patients were followed from infancy to adolescence. The median total PDI score in infancy was 102 (56–118) and the corresponding mean z-score was −0.006 (SD 0.995) and not significantly different from the reference values (p = 0.48). The median total MABC-2 score in adolescence was 75 (32–93) and the corresponding mean z-score −0.43 (SD 0.998) which is significantly below normal (p = 0.03). Children with impaired motor function in adolescence underwent significantly more rethoracotomies than those with normal motor performance (p = 0.037); whereas the two groups did not differ with respect to other clinical characteristics. Conclusion From infancy to adolescence the motor performance in the group of EA patients deteriorated from within normal range to significantly impaired compared to reference values. Interdisciplinary follow-up programs from infancy to adolescence with close monitoring for motor function is necessary to detect motor impairments.

Introduction Gastro-esophageal reflux disease (GERD) occurs frequently in patients operated for esophageal atresia (EA). Longstanding esophagitis may lead to dysphagia, strictures, columnar metaplasia, and dysplasia with an increased risk of adenocarcinoma. Are clinical factors and non-invasive assessments reliable indicators for follow-up with endoscopy? Material and method A follow-up study with inclusion of EA adolescents in Norway born between 1996 and 2002 was conducted. Clinical assessment with pH monitoring, endoscopy with biopsies, along with interviews and questionnaires regarding gastroesophageal reflux disease (GERD) and dysphagia were performed. Results We examined 68 EA adolescents. 62% reported GERD by interview, 22% by questionnaire. 85% reported dysphagia by interview, 71% by questionnaire. 24-hour pH monitoring detected pathological reflux index (RI) (>7%) in 7/59 (12%). By endoscopy with biopsy 62 (92%) had histologic esophagitis, of whom 3 (4%) had severe esophagitis. Gastric metaplasia was diagnosed in twelve (18%) adolescents, intestinal metaplasia in only one (1.5%). None had dysplasia or carcinoma. Dysphagia and GERD were statistically correlated to esophagitis and metaplasia, but none of the questionnaires or interviews alone were good screening instruments with high combined sensitivity and specificity. A compound variable made by simply taking the mean of rescaled RI and dysphagia by interview showed to be the best predictor of metaplasia (85% sensitivity, 67% specificity). Conclusion The questionnaires and interviews used in the present study were not good screening instruments alone. However, combining dysphagia score by interview and RI may be helpful in assessing which patients need endoscopy with biopsy at each individual follow-up examination.

To identify, in fetuses with a congenital lung malformation (CLM), prenatal predictors of the need for postnatal respiratory support and the need for surgery by calculating the CLM volume ratio (CVR), and to evaluate the concordance between the prenatal appearance and the postnatal type of CLM.This was an analysis of prenatal, perinatal and postnatal data from fetuses diagnosed with a CLM at the Erasmus University Medical Center - Sophia Children's Hospital in Rotterdam, The Netherlands, between January 2007 and December 2016. For all included fetuses, CVR was measured retrospectively on stored ultrasound images obtained at 18 + 1 to 24 + 6 weeks (US1), 25 + 0 to 29 + 6 weeks (US2) and/or 30 + 0 to 35 + 6 weeks' gestation (US3). Postnatal diagnosis of CLM was based on computed tomography or histology. Primary outcomes were the need for respiratory support within 24 h and surgery within 2 years after birth.Of the 80 fetuses with a CLM included in this study, 14 (18%) required respiratory support on the first postnatal day, and 17 (21%) required surgery within 2 years. Only the CVR at US2 was predictive of the need for respiratory support, with a cut-off value of 0.39. Four of 16 (25%) fetuses which showed full regression of the CLM prenatally required respiratory support within 24 h after birth. The CVR at US1, US2 and US3 was predictive of surgery within 2 years. Overall, the prenatal appearance of the CLM showed low concordance with the postnatal type. Prenatally suspected microcystic congenital pulmonary airway malformation (CPAM) was shown on computed tomography after birth to be congenital lobar overinflation in 15/35 (43%) cases. Respiratory support within 24 h after birth and surgical resection within 28 days after birth were needed in all cases of macrocystic CPAM.CVR can predict the need for respiratory support within 24 h after birth and for surgery within 2 years. Regression of a CLM prenatally does not rule out respiratory problems after birth. © 2020 The Authors.

Neonates and children who have survived critical illness severe enough to require extracorporeal membrane oxygenation (ECMO) are at risk for neurologic insults, neurodevelopmental delays, worsening of underlying medical conditions, and development of new medical comorbidities. Structured neurodevelopmental follow-up is recommended for early identification and prompt interventions of any neurodevelopmental delays. Even children who initially survive this critical illness without new medical or neurologic deficits remain at risk of developing new morbidities/delays at least through adolescence, highlighting the importance of structured follow-up by personnel knowledgeable in the sequelae of critical illness and ECMO. Structured follow-up should be multifaceted, beginning predischarge and continuing as a coordinated effort after discharge through adolescence. Predischarge efforts should consist of medical and neurologic evaluations, family education, and co-ordination of long-term ECMO care. After discharge, programs should recommend a compilation of pediatric care, disease-specific care for underlying or acquired conditions, structured ECMO/neurodevelopmental care including school performance, parental education, and support. Institutionally, regionally, and internationally available resources will impact the design of individual center's follow-up program. Additionally, neurodevelopmental testing will need to be culturally and lingually appropriate for centers' populations. Thus, ECMO centers should adapt follow-up program to their specific populations and resources with the predischarge and postdischarge components described here.

Previous studies have frequently reported neurocognitive deficits in children born with congenital diaphragmatic hernia (CDH) at school age, which may contribute to academic difficulties. Yet, age at onset of these deficits is currently unknown. We evaluated neurocognitive skills with possible determinants in preschool children born with CDH. Eligible 5-year-old children born with CDH (2010-2015) who participated in our prospective structural follow-up program were included. We used the WPPSI-III to assess intelligence, subtests of the Kaufman-ABC for memory, and NEPSY-II to assess inhibition and attention. We included 63 children. Their test scores generally were within or significantly above normal range: total IQ = 103.4 (15.7) (p = 0.13); Verbal memory = 10.2 (2.8) (p = 0.61); Visuospatial memory = 11.4 (2.6) (p 0.01); Inhibition = 10.5 (2.2), (p = 0.10). In univariable analyses, length of ICU-stay was negatively associated with IQ, and maximum vasoactive inotropic score and open repair were negatively associated with inhibition skills. In multivariable regression analysis, the latter association remained (B = 5.52, p = 0.04 (CI 0.32-10.72)). Conclusions: In these tested 5-year-old children born with CDH, neuropsychological outcome was normal on average. While problems in 8-year-olds are common, we did not detect onset of these problems at age 5. Yet, we cannot rule out that this cohort had a relatively mild level of disease severity; therefore, conclusions should be interpreted with caution. However, given the growing-into-deficit hypothesis, meaning that deviant brain development in early life is revealed once higher cognitive brain functions are demanded, follow-up should be conducted up to school age, and preferably beyond. What is Known: • Children born with CDH are at risk for academic difficulties at school age. • Whether these difficulties can be detected already before school age is unknown. What is New: • At age 5 years, intelligence, inhibition, attention, and memory skills were all within normal range, or even above, in children with CDH. This is supportive of the growing-into-deficit hypothesis in this patient population. • Those who underwent open surgical correction had poorer inhibition skills than those who were corrected with minimal access surgery.

SUMMARY Background Endoscopic surveillance of adults with esophageal atresia is advocated, but the optimal surveillance strategy remains uncertain. This study aimed to provide recommendations on appropriate starting age and intervals of endoscopic surveillance in adults with esophageal atresia. Methods Participants underwent standardized upper endoscopies with biopsies. Surveillance intervals of 3–5 years were applied, depending on age and histopathological results. Patient’s age and time to development of (pre)malignant lesions were calculated. Results A total of 271 patients with esophageal atresia (55% male; median age at baseline endoscopy 26.7 (range 15.6–68.5) years; colon interposition n = 17) were included. Barrett’s esophagus was found in 19 (7%) patients (median age 32.3 (17.8–56.0) years at diagnosis). Youngest patient with a clinically relevant Barrett’s esophagus was 20.9 years. Follow-up endoscopies were performed in 108 patients (40%; median follow-up time 4.6 years). During surveillance, four patients developed Barrett’s esophagus but no dysplasia or cancer was found. One 45-year-old woman with a colon interposition developed an adenoma with high-grade dysplasia which was radically removed. Two new cases of esophageal carcinoma were diagnosed in patients (55 and 66 years old) who were not under surveillance. One of them had been curatively treated for esophageal carcinoma 13 years ago. Conclusions This study shows that endoscopic screening of patients with esophageal atresia, including those with a colon interposition, can be started at 20 years of age. Up to the age of 40 years a surveillance interval of 10 years appeared to be safe. Endoscopic surveillance may also be warranted for patients after curative esophageal cancer treatment.

Aim As nowadays more children survive neonatal critical illness, evaluation of long‐term morbidities becomes more important. We determined whether the parent‐reported Movement Assessment Battery for Children‐Second Edition (MABC‐2) Checklist is a proper tool to screen for motor problems in school‐aged children born with severe anatomical anomalies and/or treated with neonatal extracorporeal membrane oxygenation. Methods We analysed data of 190/253 children (60.0% male) participating in our multidisciplinary follow‐up programme who were routinely assessed at the ages of five, eight and/or 12 years. Parents completed the Checklist prior to assessment of the child's actual motor performance by a physical therapist using the MABC‐2 Test. The sensitivity and specificity of the Checklist with a cut‐off point of the 16th percentile were determined. Results The sensitivity of the MABC‐2 Checklist was 57.1%, which implies that 42.9% of the children at risk for motor problems were not identified. The specificity was 79.1%. Conclusion The low sensitivity of the MABC‐2 Checklist suggests that this instrument does not suffice to screen for motor problems in children who survived neonatal critical illness. Yet, it may help to gain insight in parental perceptions of the child's motor performance and to provide tailored advice on lifestyle.

__Background:__ Patients born with esophageal atresia (EA) have a higher incidence of infantile hypertrophic pyloric stenosis (IHPS), suggestive of a relationship. A shared etiology makes sense from a developmental perspective as both affected structures are foregut derived. A genetic component has been described for both conditions as single entities and EA and IHPS are variable components in several monogenetic syndromes. We hypothesized that defects disturbing foregut morphogenesis are responsible for this combination of malformations. __Methods:__ We investigated the genetic variation of 15 patients with both EA and IHPS with unaffected parents using exome sequencing and SNP arraybased genotyping, and compared the results to mouse transcriptome data of the developing foregut. __Results:__ We did not identify putatively deleterious de novo mutations or recessive variants. However, we detected rare inherited variants in EA or IHPS disease genes or in genes important in foregut morphogenesis, expressed at the proper developmental time-points. Two pathways were significantly enriched (p < 1 × 10−5): proliferation and differentiation of smooth muscle cells and self-renewal of satellite cells. __Conclusions:__ None of our findings could fully explain the combination of abnormalities on its own, which makes complex inheritance the most plausible genetic explanation, most likely in combination with mechanical and/or environmental factors. As we did not find one defining monogenetic cause for the EA/IHPS phenotype, the impact of the corrective surgery could should be further investigated.

The aim of the present study was to evaluate whether exercise capacity can be improved in the short term and long term in children born with anatomical foregut anomalies and/or treated with extracorporeal membrane oxygenation. Therefore, we evaluated two different interventions in this single-blinded randomized controlled trial. Forty participants were randomly assigned to group A: standardized anaerobic high-intensity interval training plus online lifestyle coaching program, B: online lifestyle coaching program only, or C: standard of care.

Simple Summary We investigated the increased prevalence of Barrett's esophagus in adults with esophageal atresia. A higher polygenic risk score and disturbances in inflammatory, stress response and oncological pathways upon acid exposure suggest a genetic susceptibility and increased induction of inflammatory processes. Although further research is required to explore this hypothesis, this could be a first-step into selecting patients that are more at risk to develop Barrett's esophagus and/or esophageal carcinoma. Currently, an endoscopic screening and surveillance program is in practice in our institution for patients born with esophageal atresia, to early detect (pre)malignant lesions. Since recurrent endoscopies can be a burden for the patient, selecting patients by for example genetic susceptibility would allow to only include those at risk in future practice. The prevalence of Barrett's esophagus (BE) in adults born with esophageal atresia (EA) is four times higher than in the general population and presents at a younger age (34 vs. 60 years). This is (partly) a consequence of chronic gastroesophageal reflux. Given the overlap between genes and pathways involved in foregut and BE development, we hypothesized that EA patients have an intrinsic predisposition to develop BE. Transcriptomes of Esophageal biopsies of EA patients with BE (n = 19, EA/BE); EA patients without BE (n = 44, EA-only) and BE patients without EA (n = 10, BE-only) were compared by RNA expression profiling. Subsequently, we simulated a reflux episode by exposing fibroblasts of 3 EA patients and 3 controls to acidic conditions. Transcriptome responses were compared to the differential expressed transcripts in the biopsies. Predisposing single nucleotide polymorphisms, associated with BE, were slightly increased in EA/BE versus BE-only patients. RNA expression profiling and pathway enrichment analysis revealed differences in retinoic acid metabolism and downstream signaling pathways and inflammatory, stress response and oncological processes. There was a similar effect on retinoic acid signaling and immune response in EA patients upon acid exposure. These results indicate that epithelial tissue homeostasis in EA patients is more prone to acidic disturbances.

OBJECTIVES: To longitudinally evaluate self-reported and proxy-reported health status (HS) and quality of life (QoL) of school-aged children born with esophageal atresia (EA). METHODS: We obtained Pediatric Quality of Life Inventory (HS) and DUX-25 (QoL) questionnaires from children born with EA between 1999 and 2011 at 8 and/or 12 years old. Children completed self-reports during neuropsychological assessments in a prospective longitudinal follow-up program. Parents filled out proxy-reports at home. Total and subscale scores were evaluated longitudinally and compared with sex-specific reference norms. RESULTS: In total, 110 participants (62% boys) were included. Self-reported HS improved significantly between 8 and 12 years for both boys (mean difference [md] 4.35, effect size [ES] 0.54, P = 0.009) and girls (md 3.26, ES 0.63, P = 0.004). Proxy-reported HS tended to improve over time, while self-reported and proxy-reported QoL tended to decline. Self-reported HS at 8 years was below normal for both boys (md -5.44, ES -0.35, P

Supplemental Digital Content is available in the text, Objectives: The aim of the study was to evaluate acid and nonacid gastroesophageal reflux in infants and school-aged children with esophageal atresia (EA) using pH-impedance (pH-MII) monitoring. Methods: Between 2012 and 2017, all 24-hour pH-MII studies performed in infants (≤18 months) and 8-year olds with EA were included. Antiacid therapy was discontinued before study. Exclusion criteria were: isolated tracheoesophageal fistula; esophageal replacement therapy; tube feeding; and monitoring

Objective To improve counseling on congenital lung malformations (CLM) by describing long‐term outcomes of children either operated on or managed by observation. Study design We analyzed lung function (spirometry), exercise tolerance (Bruce treadmill), and physical growth of 8‐year‐old children with CLM who participated in our longitudinal prospective follow‐up program. The data are shown as median standard deviation scores (SDS) with IQR, or estimated marginal means (95% CI) on the basis of general linear models. Results Twenty‐nine (48%) of the 61 children had required surgery at a median age of 108 (IQR: 8‐828) days, and 32 (52%) were managed by observation. In the surgery group, all lung function measurements (except for forced vital capacity [FVC]) were significantly below 0 SDS, with median FEV1 −1.07 (IQR: −1.70 to −0.56), FEV1/FVC −1.49 (−2.62 to −0.33), and FEF25%‐75% −1.95 (−2.57 to −0.63) (all P

Objective Children with congenital diaphragmatic hernia (CDH) are at risk for pulmonary morbidity. Data on longitudinal evaluation of lung function in CDH are scarce. We hypothesized that CDH patients would have impaired lung function that worsens over time. We evaluated lung function and its determinants at ages 8 and 12 years. Methods Dynamic and static lung volumes, and diffusion capacity were measured. Extracorporeal membrane oxygenation (ECMO) treatment, the standardized European neonatal treatment protocol, patch repair, duration of ventilation, type of initial mechanical ventilation, and nitric oxide treatment were entered as covariates in linear mixed models with standard deviation score (SDS) lung function parameters (FEV1, FEF 25‐75, and K CO) as dependent variables. Results Seventy‐six children (27 ECMO‐treated) born between 1999 and 2009 performed 113 reliable lung function tests. Severity of airflow obstruction deteriorated significantly from age 8 to 12 years: estimated mean difference (95% confidence interval [CI]) SDS FEV1 was −0.57 (−0.79 to −0.36) and SDS FEF25‐75 was −0.63 (−0.89 to −0.37), both P

Objective:With increasing numbers of children growing up with conditions that are associated with acquired brain injury, efficient neuropsychological screening for cognitive deficits is pivotal. Brief self-report measures concerning daily complaints can play an important role in such screening. We translated and adapted the pediatric perceived cognitive functioning (PedsPCF) self- and parent-report item bank to Dutch. This study presents (1) psychometric properties, (2) a new short form, and (3) normative data for the short form.Methods:A general population sample of children and parents was recruited. Dimensionality of the PedsPCF was assessed using confirmatory factor analyses and exploratory bifactor analyses. Item response theory (IRT) modeling was used to evaluate model fit of the PedsPCF, to identify differential item functioning (DIF), and to select items for the short form. To select short-form items, we also considered the neuropsychological content of items.Results:In 1441 families, a parent and/or child participated (response rate 66% at family level). Assessed psychometric properties were satisfactory and the predominantly unidimensional factor structure of the PedsPCF allowed for IRT modeling using the graded response model. One item showed meaningful DIF. For the short form, 10 items were selected.Conclusions:In this first study of the PedsPCF outside the United States, studied psychometric properties of the translated PedsPCF were satisfactory, and allowed for IRT modeling. Based on the IRT analyses and the content of items, we proposed a new 10-item short form. Further research should determine the relation of PedsPCF outcomes with neurocognitive measures and its ability to facilitate neuropsychological screening in clinical practice.

Introduction We aimed to investigate QoL in EA patients in relation to comparison groups and to clinical factors including experienced traumatic stress. Material and Methods Adolescents with EA in Norway born between 1996 and 2002 were included. Clinical assessment and patient's characteristics were collected. Quality of life (PedsQL), traumatic stress (IES-13) and mental health (SDQ-20) were compared to groups of healthy controls, children with acute lymphoblastic leukemia (ALL) and kidney transplanted children (TX). Results 68 EA adolescents participated. Total scores for PedsQL were not different from the healthy group and ALL patients, but significantly better than the TX patients. The subscale for physical performance was significantly lower than in healthy adolescents, and nine (17%) patients had scores ≤70 indicating reduced health status. Five EA adolescents (12%) had mental health scores suggesting a psychiatric disorder, and six (9%) reported high traumatic stress scores with a significant correlation to days on ventilator in the neonatal period. The strongest predictors for quality of life among EA adolescents were self-reported mental health, posttraumatic stress and GERD symptoms. Conclusion Scores for Quality of life in the EA group are good except for subscale for physical performance. Symptoms of posttraumatic stress, mental strain and gastroesophageal reflux are predictors of reduced QoL.

Objectives: To test the immediate and long-term effectiveness of Cogmed Working Memory Training following extracorporeal membrane oxygenation and/or congenital diaphragmatic hernia.Design: A nationwide randomized controlled trial assessing neuropsychologic outcome immediately and 1 year post Cogmed Working Memory Training, conducted between October 2014 and June 2017. Researchers involved in the follow-up assessments were blinded to group allocation.Setting: Erasmus MC-Sophia Children's Hospital, Rotterdam, and Radboud University Medical Center, Nijmegen, the Netherlands.Patients: Eligible participants were neonatal extracorporeal membrane oxygenation and/or congenital diaphragmatic hernia survivors (8-12 yr) with an intelligence quotient greater than or equal to 80 and a z score less than or equal to -1.5 on at least one (working) memory test at first assessment.Interventions: Cogmed Working Memory Training, comprising 25 45-minute training sessions for 5 consecutive weeks at home.Measurements and main results: Participants were randomized to Cogmed Working Memory Training (n = 19) or no intervention (n = 24) (two dropped out after T0). Verbal working memory (estimated coefficient = 0.87; p = 0.002) and visuospatial working memory (estimated coefficient=0.96, p = 0.003) significantly improved at T1 post Cogmed Working Memory Training but was similar between groups at T2 (verbal, p = 0.902; visuospatial, p = 0.416). Improvements were found at T2 on long-term visuospatial memory following Cogmed Working Memory Training (estimated coefficient = 0.95; p = 0.003). Greater improvements in this domain at T2 following Cogmed Working Memory Training were associated with better self-rated school functioning (r = 0.541; p = 0.031) and parent-rated attention (r = 0.672; p = 0.006).Conclusions: Working memory improvements after Cogmed Working Memory Training disappeared 1 year post training in neonatal extracorporeal membrane oxygenation and/or congenital diaphragmatic hernia survivors. Gains in visuospatial memory persisted 1 year post intervention. Cogmed Working Memory Training may be beneficial for survivors with visuospatial memory deficits.

Contains fulltext : 196124.pdf (Publisher’s version ) (Closed access) Over the past decade, evidence has emerged that children growing up after neonatal critical illness, irrespective of underlying diagnosis, are at risk of memory impairment and academic problems. These difficulties are manifest even when intelligence is within the normal range. In this Review, we propose a common neurodevelopmental pathway following neonatal critical illness by showing that survivors of preterm birth, congenital heart disease, and severe respiratory failure share an increased risk of long-term memory deficits and associated hippocampal alterations. Rather than a consequence of underlying diagnosis, we suggest that this shared vulnerability is probably related to common conditions associated with neonatal critical illness, including hypoxia, neuroinflammation, stress, exposure to anaesthetics, or a complex interplay of these factors at different postconceptional ages. Future work should be aimed at improvement of early identification of patients at risk and evaluation of intervention modalities, such as exercise or cognitive training.

Increasing numbers of children and adults with chronic disease status highlight the need for a value-based healthcare system. Patient-reported outcome measures (PROMs) are essential to value-based healthcare, yet it remains unclear how they relate to clinical outcomes such as health and daily functioning. We aimed to assess the added value of self-reported PROMs for health status (HS) and quality of life (QoL) in the long-term follow-up of children with foregut anomalies. We evaluated data of PROMs for HS and/or QoL among eight-year-olds born with congenital diaphragmatic hernia (CDH), esophageal atresia (EA), or congenital lung malformations (CLM), collected within the infrastructure of a multidisciplinary, longitudinal follow-up program. Clinical outcomes were categorized into different outcome domains, and their relationships with self-reported HS and QoL were assessed through multivariable linear regression analyses. A total of 220 children completed HS and/or QoL self-reports. In children with CDH and EA, lower cognition was significantly associated with lower self-reported HS. Due to the low number of cases, multivariable linear regression analysis was not possible in children with CLM. HS, QoL, and clinical outcomes represent different aspects of a child’s wellbeing and should be measured simultaneously to facilitate a more holistic approach to clinical decision making.

Treatment modalities for newborns with anatomical congenital anomalies have greatly improved over the past decades, with a concomitant increase in survival. This review will briefly discuss specific long-term outcomes to illustrate, which domains deserve to be considered in long-term follow-up of patients with anatomical congenital anomalies. Apart from having disease-specific morbidities these children are at risk for impaired neurodevelopmental problems and school failure, which may affect participation in society in later life. There is every reason to offer them long-term multidisciplinary follow-up programs. We further provide an overview of the methodology of long-term follow-up, its significance and discuss ways to improve care for newborns with anatomical congenital anomalies from childhood into adulthood. Future initiatives should focus on transition of care, risk stratification, and multicenter collaboration.

ObjectiveWe aimed to identify gestational-age corrected prenatal ultrasound markers of complex gastroschisis, and to compare physical growth and neurodevelopment between children with simple and complex gastroschisis.DesignWe included prenatally diagnosed gastroschisis patients from 2000 to 2012 who joined our longitudinal follow-up programme. Associations between complex gastroschisis and prenatal ultrasound markers collected at 30 weeks’ gestation and prior to delivery were tested using logistic regression. Physical growth (SD scores (SDS)), mental and psychomotor developmental index (MDI, PDI; Bayley Scales of Infant Development) were recorded at 12 and 24 months. Data were analysed using general linear models and compared with population norms.ResultsData of 61 children were analysed (82% of eligible cases). Extra-abdominal bowel dilatation at 30 weeks’ gestation was significantly associated with complex gastroschisis (OR (95% CI): 5.00 (1.09 to 22.98)), with a high negative (88%) but low positive (40%) predictive value. The mean (95% CI) height SDS at 12 months (−0.46 (–0.82 to –0.11)), and weight SDS at 12 and 24 months (−0.45 (–0.85 to –0.05), and −0.44 (−0.87 to –0.01), respectively) fell significantly below 0 SDS. MDI and PDI were significantly below 100 at 24 months; 93 (88 to 99) and 83 (78 to 87), respectively). Children with complex gastroschisis had a significantly lower PDI (76 (68 to 84)) than those with simple gastroschisis (94 (90 to 97), pConclusionsPrenatal ultrasound markers could not reliably distinguish between simple and complex gastroschisis. Children with complex gastroschisis may be at increased risk for delayed psychomotor development; they should be monitored more closely, and offered timely intervention.

Objective To assess the predictive value of observed-to-expected lung-to-head ratio (O/E LHR) for survival and chronic lung disease (CLD) in survivors of left-sided congenital diaphragmatic hernia (CDH) in an era of standardized neonatal treatment, and to evaluate the predictive value of the O/E LHR trajectory for survival. Methods This retrospective cohort study was performed in two high-volume CDH centers in the Netherlands in prenatally detected, isolated left-sided CDH patients born between 2008 and 2014. O/E LHR and liver position were determined using 2D-ultrasonography at three time points during gestation from 19 weeks onwards. Ultrasound measurements were performed on stored ultrasound data by one single experienced operator blinded to postnatal outcome. Results Of the 122 included cases, 77.9% survived of whom 38.9% developed CLD. A significant association was found between the first measured O/E LHR and survival and development of CLD in survivors. Prenatal liver position did not have additional predictive value. No significant association was found between the trajectory of the O/E LHR and survival. Conclusion In an era of standardized neonatal treatment for neonates with CDH, the first measured O/E LHR per patient significantly predicts survival and development of CLD in survivors in isolated left-sided CDH infants. © 2017 The Authors.

BACKGROUND AND AIMS Data on long-term outcome of exercise capacity in school-aged children with esophageal atresia (EA) are scarce. We evaluated maximal exercise capacity and its relation to lung function. Moreover, we studied other possible determinants of exercise capacity and lung function. METHODS Exercise capacity of 63 children with EA born 1999-2007 was evaluated at the age of 8 years with the Bruce-protocol. Dynamic and static lung volumes, bronchodilator response and diffusion capacity were measured. Furthermore, perinatal characteristics, hospital admissions for lower respiratory tract infections (RTIs), RTIs treated with antibiotics in the past year, symptoms of gastroesophageal reflux, weight-for-height, and sports participation were evaluated as other potential determinants. RESULTS Exercise capacity was significantly below normal: mean (SD) SDS -0.91 (0.97); P

Objective Previous studies reported diminished growth after oesophageal atresia (OA) repair. We evaluated long-term follow-up data on growth. Methods Longitudinal cohort study up to 12 years. Patients with OA, born 1999–2013, who participated in a longitudinal follow-up programme were included. Children with genetic syndromes associated with growth disorders were excluded. SD scores (SDS) for height-for-age (HFA), weight-for-height (WFH) and distance-to-target-height were calculated for routine visits (0.5/1/2/5/8/12 years). Linear mixed models were used to estimate SDS until 12 years of age and to evaluate explanatory factors for growth. Results We included 126/155 children (32% prematurely born, 20% small for gestational age), 32 reached the age of 12 years. Fundoplication surgery was performed in 24%. SDS-HFA was below normal up to 8 years but improved over these years (mean (SE) −0.48 (0.09), −0.31 (0.09) and −0.20 (0.13) at 0.5, 8 and 12 years). Scores improved after correction for target height (mean (SE) −0.29 (0.10), −0.17 (0.09) and −0.10 (0.14) at 0.5, 8 and 12 years). SDS-WFH was below normal from age 1–5 years (mean (SE) −0.53 (0.09), −0.24 (0.09) and 0.03 (0.14) at 1, 5 and 12 years). Low birth weight and fundoplication surgery were negatively associated with growth. Conclusions The growth of patients with OA was below the reference norm during the first years of life, but normalised at 12 years. Large longitudinal cohort studies should evaluate if normal growth persists into adolescence. Early nutritional assessment with timely dietary intervention should be considered especially in those with low birth weight or following fundoplication surgery.

Aim of the Study Because of the high prevalence of Barrett's esophagus (BE) and esophageal carcinoma, it is internationally recommended to perform routine endoscopies in adult esophageal atresia (EA) patients. This study aimed to evaluate the yield of follow-up after the first screening endoscopy. Methods Prospective cohort study in a tertiary referral center since November 2011 was considered. All patients with EA ≥ 17 years old were invited to participate in the screenings and surveillance program. All patients underwent upper endoscopies with random biopsies of the distal esophagus at the level of the gastroesophageal junction and standard four-quadrant biopsies in case of BE. From the age of 25 years old chromoendoscopy with Lugol's staining was performed for detection of superficial squamous cell carcinoma. Depending on their age and the histologic results patients were recommended follow-up endoscopy every 3–5 years. Ethical approval had been obtained. Results In February 2019, 190 patients (58% male, 83% type C, median age at time of first endoscopy 25.5) (range: 16.8–68.6 years) participated in the screenings and surveillance program. Forty-six patients underwent at least one follow-up endoscopy after median 4.7 (range: 1.0–5.9) years. Most recent surveillance endoscopy revealed a normal esophagus in 62%, esophagitis in 10%, and columnar-lined esophagus in 26% of the patients. Histology revealed inflammatory changes within normal limits in 49%, esophagitis in 22%, gastric metaplasia in 18%, and intestinal metaplasia without dysplasia in 6%. In 8 patients (6 males, median age: 25.9 (range: 22.5–34.4)) columnar-lined mucosa was a new finding at the second endoscopy, after median 5.0 (range: 3.6–5.9) years. In two of them histology revealed intestinal metaplasia without dysplasia. Conclusions In line with previous studies, we found a 4-times increased prevalence (6.3%) of BE in adults with EA. Follow-up endoscopies detected two new cases of BE. Future studies are needed to identify patients at risk and personalize screening and surveillance regimes.

Aim of the Study Patients born with esophageal atresia (EA) appear to have a 30 times higher prevalence of infantile hypertrophic pyloric stenosis (IHPS). This makes sense from a developmental perspective as both the esophagus and the pyloric sphincter are foregut derived structures. We hypothesized that genetic defects, disturbing foregut morphogenesis, are responsible for the specific combination of EA and IHPS. Methods Patients with both EA and IHPS born between 1970 and 2017 and where possible their parents were included. This study was approved by the internal review board of the Erasmus MC. After parental written informed consent, we determined genetic profiles with whole exome sequencing and SNP-array-based copy number variation analysis. We focused on (1) genetic variation in known EA and IHPS disease genes, (2) pathways important for foregut morphogenesis, (3) shared rare genetic variation, and (4) ultrarare variants in variant-intolerant genes, which have a high chance of being de novo. Segregation analysis of possible candidate variants was performed. Results Twenty-seven out of 664 patients (4.1%) born with EA during the study period developed IHPS, of which 15 cases were analyzed. As none of the parents were affected, we considered dominant (de novo) or recessive and X-linked inheritance models. Unfortunately, we could neither identify rare de novo mutations, nor variants fitting a recessive model. We did however identify inherited putative deleterious heterozygous variants in genes either known to be involved in EA or IHPS (e.g., COL7A1, TNXB, WDR11, GDF6) or important in foregut morphogenesis (e.g., GLI3, NKX2.1) in all patients. Moreover, seven genes were affected by rare variation in ≥2 patients (ADAMTSL4, ANKRD26, CNTN2, HSPG2, KCNN3, LDB3, SEC16B) and expressed in the developing foregut, esophagus or pyloric sphincter in mice between E8.25 and E18.5. However, burden analysis did not show a significant difference with unaffected controls. Conclusions Although the presence of genetic variation in likely candidate genes suggests a genetic component, genetic factors alone could not explain the abnormalities seen in these patients. Therefore, we propose a multifactorial model in which the combination of high impact genetic, mechanical, and environmental factors together can shift the balance from normal to abnormal development.

Patients born with esophageal atresia (EA) have a 30 times higher prevalence of infantile hypertrophic pyloric stenosis (IHPS). This makes sense from a developmental perspective as both the esophagus and the pyloric sphincter are foregut derived structures. EA and IHPS are variable features in several (monogenetic) syndromes. This, and twin and familial studies, indicates a genetic component for both conditions as single entities. We hypothesized that genetic defects, disturbing foregut morphogenesis, are responsible for this combination of malformations. Non-genetic factors could also contribute, as mice exposed to Adriamycin develop EA andin uterodiethylstilbestrol exposure is associated with EA.We investigated the copy number profiles and protein coding variants of 15 patients with both EA and IHPS. As all parents were unaffected, we first considered dominant(de novo)or recessive inheritance models but could not identify putatively deleterious mutations or recessive variants. We did identify inherited variants in genes either known to be involved in EA or IHPS or important in foregut morphogenesis in all patients. Unfortunately, variant burden analysis did not show a significant difference with unaffected controls. However, the IHPS associated risk SNP rs1933683 had a significantly higher incidence (OR 3.29, p=0.009).Although the genetic variation in likely candidate genes as well as the predisposing locus nearBARX1(rs1933683) suggest a genetic component, it does not fully explain the abnormalities seen in these patients. Therefore, we hypothesize that a combination of high impact genetic, mechanical and environmental factors together can shift the balance to abnormal development.Summary statementInstead of one affected gene, the higher incidence of IHPS in EA patients is more likely the result of multiple (epi)genetic and environmental factors together shifting the balance to disease development.

Objective To determine the predictive value of the fetal omphalocele circumference/abdominal circumference (OC/AC) ratio for type of surgical closure and survival and to describe the trajectory of OC/AC ratio throughout gestation. Methods This cohort study included all live‐born infants prenatally diagnosed with an omphalocele in our tertiary centre (2000–2017) with an intention to treat. The OC/AC ratio and liver position were determined using 2D ultrasound at three periods during gestation (11–16, 17–26, and/or 30–38 weeks). Primary outcome was type of closure; secondary outcome was survival. In the secondary analyses, the predictive value of the OC/AC‐ratio trend for type of closure and survival was assessed. Results Primary closure was performed in 37/63 (59%) infants, and 54/63 (86%) survived. The OC/AC ratio was predictive for type of closure and survival in all periods. Optimal cut‐off values for predicting closure decreased throughout gestation from 0.69 (11–16 weeks) to 0.63 (30–38 weeks). Repeated OC/AC‐ratio measurements were available in 33 (73%) fetuses. The trend of the OC/AC ratio throughout gestation was not significantly associated with type of closure. All infants without liver herniation underwent primary closure. Conclusion Type of omphalocele surgical closure and survival can be predicted prenatally on the basis of the OC/AC ratio and liver herniation independent of associated anomalies. Learning objective The reader will be able to use the OC/AC ratio throughout gestation in all omphalocele cases for prediction of type of closure and survival and thus patient counselling., What's already known about this topic? In fetuses with an isolated omphalocele, the OC/AC ratio is less than 24 weeks; gestation is of predictive value for postnatal type of closure. What does this study add? The OC/AC ratio is predictive for type of surgical closure and survival in all fetuses with an omphalocele.This report is the first concerning the trend of the OC/AC ratio throughout gestation.The OC/AC ratio best predicts type of closure and survival in the third trimester of pregnancy.

Children with gastroschisis are at high risk of morbidity in early life, which could affect long-term outcomes. We determined parent-reported outcomes in school-aged children born in 2000–2012, using paper questionnaires. Parent-perceived child vulnerability and motor function were compared with the Dutch reference data; parent-rated data on cognition, health status, quality of life, and behavior were compared with those of controls matched for age, gender, and maternal education level. Of 77 eligible participants, 31 (40%) returned the questionnaires. Parent-reported motor function was normal in 23 (74%) children. Total scores on health status, quality of life, and behavior did not differ significantly from those of matched controls. Children with gastroschisis had lower scores on cognition (median (interquartile range); 109 (87–127)) than their matched controls (124 (113–140); p = 0.04). Neonatal intestinal failure and increased parent-perceived vulnerability were associated with lower scores on cognition (β − 25.66 (95% confidence interval − 49.41, − 1.91); − 2.76 (− 5.27, − 0.25), respectively). Conclusion: Parent-reported outcomes of school-aged children with gastroschisis were mainly reassuring. Clinicians and parents should be aware of the higher risk of cognitive problems, especially in those with neonatal intestinal failure or increased parent-perceived vulnerability. We recommend multidisciplinary follow-up at school age of children with gastroschisis and neonatal intestinal failure. What is Known: • Many infants with gastroschisis experience morbidity in early life.• Data on developmental outcomes and daily functioning in children with gastroschisis beyond the age of 5 years are scarce and conflicting. What is New: • Parents of school-aged children treated for gastroschisis report normal motor function, health status, quality of life, and behavior.• Children with gastroschisis, especially those with intestinal failure, may be at risk for cognitive problems at school age. Parents who reported their child as being more vulnerable also reported more cognitive problems at school age.

ObjectiveTo determine the incidence of refractory anastomotic strictures after oesophageal atresia (OA) repair and to identify risk factors associated with refractory strictures.MethodsRetrospective national multicentre study in patients with OA born between 1999 and 2013. Exclusion criteria were isolated fistula, inability to obtain oesophageal continuity, death prior to discharge and follow-up ResultsWe included 454 children (61% male, 7% isolated OA (Gross type A)). End-to-end anastomosis was performed in 436 (96%) children. Anastomotic leakage occurred in 13%. Fifty-eight per cent of children with an end-to-end anastomosis developed an anastomotic stricture, requiring a median of 3 (range 1–34) dilations. Refractory strictures were found in 32/436 (7%) children and required a median of 10 (range 5–34) dilations. Isolated OA (OR 5.7; p=0.012), anastomotic leakage (OR 5.0; p=0.001) and the need for oesophageal dilation ≤28 days after anastomosis (OR 15.9; pConclusionsThe incidence of refractory strictures of the end-to-end anastomosis in children treated for OA was 7%. Risk factors were isolated OA, anastomotic leakage and the need for oesophageal dilation less than 1 month after OA repair.

Objective Many children with omphalocele experience morbidity in early life, which could affect long-term outcomes. We determined parent-reported outcomes in school-aged children treated for minor or giant omphalocele. Study design We sent paper questionnaires to the parents of all children treated for omphalocele in 2000–2012. Giant omphalocele was defined as defect diameter ≥ 5 cm with liver protruding. Motor function (MABC-2 Checklist) was compared with Dutch reference data; cognition (PedsPCF), health status (PedsQL), quality of life (DUX-25) and behavior (Strengths and Difficulties Questionnaire; SDQ) were compared with those of controls (two per child) matched for age, gender and maternal education level. Possible predictors of cognition and behavior were evaluated using linear regression analyses. Results Of 54 eligible participants, 31 (57%) returned the questionnaires. MABC-2 Checklist scores were normal for 21/26 (81%) children. Cognition, health status, quality of life and behavior were similar to scores of matched controls. One quarter (26%) of children with omphalocele scored ≤ − 1 standard deviation on the PedsPCF, compared with 9% of matched controls (p = 0.07). Giant omphalocele and presence of multiple congenital anomalies (MCA) were most prominently associated with lower PedsPCF scores (giant omphalocele: β −22.11 (95% CI: −43.65 to −0.57); MCA -23.58 (−40.02 to −7.13)), although not significantly after correction for multiple testing. Conclusions Parent-reported outcomes of children with omphalocele at school age are reassuring. Children with an isolated, minor omphalocele do not need extensive long-term follow-up of daily functioning. Those with a giant omphalocele or MCA might be at risk for delayed cognitive functioning at school age; we recommend long-term follow-up to offer timely intervention.

ObjectivesTo compare the prenatal frame of reference of omphalocele (ie, survival of fetuses) with that after birth (ie, survival of liveborn neonates), and to assess physical growth and neurodevelopment in children with minor or giant omphalocele up to 2 years of age.DesignWe included fetuses and neonates diagnosed in 2000–2012. Physical growth (SD scores, SDS) and mental and motor development at 12 and 24 months were analysed using general linear models, and outcomes were compared with reference norms. Giant omphalocele was defined as defect ≥5 cm, with liver protruding.ResultsWe included 145 fetuses and neonates. Of 126 (87%) who were diagnosed prenatally, 50 (40%) were liveborn and 35 (28%) survived at least 2 years. Nineteen (13%) neonates were diagnosed after birth. Of the 69 liveborn neonates, 52 (75%) survived and 42 children (81% of survivors) were followed longitudinally. At 24 months, mean (95% CI) height and weight SDS were significantly below 0 in both minor (height: −0.57 (−1.05 to –0.09); weight: −0.86 (−1.35 to –0.37)) and giant omphalocele (height: −1.32 (−2.10 to –0.54); weight: −1.58 (−2.37 to –0.79)). Mental development was comparable with reference norms in both groups. Motor function delay was found significantly more often in children with giant omphalocele (82%) than in those with minor omphalocele (21%, P=0.002).ConclusionsThe prenatal and postnatal frames of reference of omphalocele differ considerably; a multidisciplinary approach in parental counselling is recommended. As many children with giant omphalocele had delayed motor development, we recommend close monitoring of these children and early referral to physical therapy.
