Developmental outcomes at 3 years of age following major non-cardiac and cardiac surgery in term infants: A population-based study

Comprehensive analyses of neurodevelopmental outcomes and quality of life of children with biliary atresia

OBJECTIVES

To holistically evaluate neurodevelopmental outcomes and quality of life (QOL) of Japanese patients with biliary atresia (BA) and to investigate the factors associated with the outcomes.

METHODS

This study enrolled patients with BA aged 5-18 years who visited Osaka University Hospital in 2021. Neurodevelopmental assessments were performed to evaluate intellectual ability, cognitive functions and adaptive skill levels. Furthermore, emotional and behavioral issues, characteristics of attention deficit hyperactivity disorder, and QOL were concomitantly assessed in the same cohort. Biochemical and social factors associated with the results were examined.

RESULTS

Fifty-three patients, with a median age of 11.2 years were included in the analyses. Patients with BA had a significantly lower Full-Scale Intelligence Quotient or developmental quotient (FSIQ/DQ) score and Vineland Adaptive Behavior Scale (VABS) composite score than the general Japanese population. Household education level and short stature were associated with low and borderline FSIQ/DQ and VABS composite scores, respectively. Among patients with low and borderline FSIQ/DQ scores, those with average or high VABS composite scores received significantly less neuroeducational care than those with low and borderline VABS composite scores. Despite the low FSIQ/DQ and VABS composite scores, the total QOL scores were higher than those of the general population.

CONCLUSION

Patients with BA had intellectual and behavioral impairments. Notably, patients with intellectual impairments are overlooked and not followed up, especially if adaptive skills are maintained.

A comparison of ultrafast and conventional spectral Doppler ultrasound to measure cerebral blood flow velocity during inguinal hernia repair in infants

BACKGROUND

Ultrafast cerebral Doppler ultrasound enables simultaneous quantification and visualization of cerebral blood flow velocity. The aim of this study is to compare the use of conventional and ultrafast spectral Doppler during anesthesia and their potential to show the effect of anesthesiologic procedures on cerebral blood flow velocities, in relation to blood pressure and cerebral oxygenation in infants undergoing inguinal hernia repair.

METHODS

A single-center prospective observational cohort study in infants up to six months of age. We evaluated conventional and ultrafast spectral Doppler cerebral ultrasound measurements in terms of number of successful measurements during the induction of anesthesia, after sevoflurane induction, administration of caudal analgesia, a fluid bolus and emergence of anesthesia. Cerebral blood flow velocity was quantified in pial arteries using conventional spectral Doppler and in the cerebral cortex using ultrafast Doppler by peak systolic velocity, end diastolic velocity and resistivity index.

RESULTS

Twenty infants were included with useable conventional spectral Doppler images in 72/100 measurements and ultrafast Doppler images in 51/100 measurements. Intraoperatively, the success rates were 53/60 (88.3%) and 41/60 (68.3%), respectively. Cerebral blood flow velocity increased after emergence for both conventional (end diastolic velocity, from 2.01 to 2.75 cm/s, p < 0.001) and ultrafast spectral Doppler (end diastolic velocity, from 0.59 to 0.94 cm/s), whereas cerebral oxygenation showed a reverse pattern with a decrease after the emergence of the infant (85% to 68%, p < 0.001).

CONCLUSION

It is possible to quantify cortical blood flow velocity during general anesthesia using conventional and ultrafast spectral Doppler cerebral ultrasound. Cerebral blood flow velocity and blood pressure decreased, while regional cerebral oxygenation increased during general anesthesia. Ultrafast spectral Doppler ultrasound offers novel insights into perfusion within the cerebral cortex, unattainable through conventional spectral ultrasound. Yet, ultrafast Doppler is curtailed by a lower success rate and a more rigorous learning curve compared to conventional method.

Brain injury and long-term outcome after neonatal surgery for non-cardiac congenital anomalies

BACKGROUND

There is growing evidence that neonatal surgery for non-cardiac congenital anomalies (NCCAs) in the neonatal period adversely affects long-term neurodevelopmental outcome. However, less is known about acquired brain injury after surgery for NCCA and abnormal brain maturation leading to these impairments.

METHODS

A systematic search was performed in PubMed, Embase, and The Cochrane Library on May 6, 2022 on brain injury and maturation abnormalities seen on magnetic resonance imaging (MRI) and its associations with neurodevelopment in neonates undergoing NCCA surgery the first month postpartum. Rayyan was used for article screening and ROBINS-I for risk of bias assessment. Data on the studies, infants, surgery, MRI, and outcome were extracted.

RESULTS

Three eligible studies were included, reporting 197 infants. Brain injury was found in n = 120 (50%) patients after NCCA surgery. Sixty (30%) were diagnosed with white matter injury. Cortical folding was delayed in the majority of cases. Brain injury and delayed brain maturation was associated with a decrease in neurodevelopmental outcome at 2 years of age.

CONCLUSIONS

Surgery for NCCA was associated with high risk of brain injury and delay in maturation leading to delay in neurocognitive and motor development. However, more research is recommended for strong conclusions in this group of patients.

IMPACT

Brain injury was found in 50% of neonates who underwent NCCA surgery. NCCA surgery is associated with a delay in cortical folding. There is an important research gap regarding perioperative brain injury and NCCA surgery.

Risk of Developmental Coordination Disorder in 8- and 9-Year-Olds Following Newborn Cardiac and Non-Cardiac Surgery

PURPOSE

To investigate the risk of developmental coordination disorder (DCD) and motor impairment for children aged 8 to 9 years following newborn surgery.

METHODS

Prospective longitudinal cohort study. Motor proficiency and risk of DCD were assessed using the Movement Assessment Battery for Children (second edition) for children born 37 weeks of gestation and older who had undergone newborn cardiac surgery (CS) or non-cardiac surgery (NCS).

RESULTS

Children who had undergone CS were 3.0 times more likely than controls and 1.7 times more likely than children who had undergone NCS to score below the 15th centile on MABC-2 and have increased risk of DCD. Children who had undergone CS were 1.9 times more likely than controls and 1.4 times more likely than children who had undergone NCS to score below the fifth centile on MABC-2.

CONCLUSION

The surgical population should be considered at an increased risk of DCD.

A guide to prenatal counseling regarding neurodevelopment in congenital heart disease

Advances in cardiac surgical techniques taking place over the past 50 years have resulted in the vast majority of children born with congenital cardiac malformations now surviving into adulthood. As the focus shifts from survival to the functional outcomes of our patients, it is increasingly being recognized that a significant proportion of patients undergoing infant cardiac repair experience adverse neurodevelopmental (ND) outcomes. The etiology of abnormal brain development in the setting of congenital heart disease is poorly understood, complex, and likely multifactorial. Furthermore, the efficacy of therapies available for the learning disabilities, attention deficit, and hyperactivity disorders and other ND deficits complicating congenital heart disease is currently uncertain. This situation presents a challenge for prenatal counseling as current antenatal testing does not usually provide prognostic information regarding the likely ND trajectories of individual patients. However, we believe it is important for parents to be informed about potential issues with child development when a new diagnosis of congenital heart disease is disclosed. Parents deserve a comprehensive and thoughtful approach to this subject, which conveys the uncertainties involved in predicting the severity of any developmental disorders encountered, while emphasizing the improvements in outcomes that have already been achieved in infants with congenital heart disease. A balanced approach to counseling should also discuss what local arrangements are in place for ND follow-up. This review presents an up-to-date overview of ND outcomes in patients with congenital heart disease, providing possible approaches to communicating this information to parents during prenatal counseling in a sensitive and accurate manner.

Growth and risk of adverse neurodevelopmental outcome in infants with congenital surgical anomalies: a systematic review

Survival of infants with congenital anomalies requiring surgical correction has increased dramatically, shifting the focus of clinical care and research toward optimising growth and neurodevelopment.To determine the impact of growth on neurodevelopmental outcomes of infants with congenital surgical anomalies. Studies that reported association of growth with developmental outcomes in infants with congenital anomalies who had surgery, were eligible for inclusion. The search strategy was prospectively drafted, and relevant studies were identified by electronic searches. The Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library 2022, issue 1), MEDLINE and EMBASE from their earliest date to February 2022 were searched. Seven studies met the inclusion criteria. Variability in selection of growth measures, developmental assessment tools and assessment endpoints for neurodevelopment, precluded a meta-analysis. Four studies reported the association between growth and neurodevelopmental outcomes in infants with gastroschisis with two noting adverse outcomes in infants who were small for gestational age. Birthweight, reported in four studies, was not associated with adverse developmental outcomes. Postnatal growth, reported in three studies, was associated with adverse outcome. The data linking growth restriction in infants with congenital surgical anomalies and neurodevelopmental outcome is limited. There is limited published research examining the longitudinal effects of intra- and extra-uterine growth parameters on neurodevelopmental outcomes.

Impact of Comorbid Prematurity and Congenital Anomalies: A Review

Preterm infants are more likely to be born with congenital anomalies than those who are born at full-term. Conversely, neonates born with congenital anomalies are also more likely to be born preterm than those without congenital anomalies. Moreover, the comorbid impact of prematurity and congenital anomalies is more than cumulative. Multiple common factors increase the risk of brain injury and neurodevelopmental impairment in both preterm babies and those born with congenital anomalies. These include prolonged hospital length of stay, feeding difficulties, nutritional deficits, pain exposure and administration of medications including sedatives and analgesics. Congenital heart disease provides a well-studied example of the impact of comorbid disease with prematurity. Impaired brain growth and maturity is well described in the third trimester in this population; the immature brain is subsequently more vulnerable to further injury. There is a colinear relationship between degree of prematurity and outcome both in terms of mortality and neurological morbidity. Both prematurity and relative brain immaturity independently increase the risk of subsequent neurodevelopmental impairment in infants with CHD. Non-cardiac surgery also poses a greater risk to preterm infants despite the expectation of normal in utero brain growth. Esophageal atresia, diaphragmatic hernia and abdominal wall defects provide examples of congenital anomalies which have been shown to have poorer neurodevelopmental outcomes in the face of prematurity, with associated increased surgical complexity, higher relative cumulative doses of medications, longer hospital and intensive care stay and increased rates of feeding difficulties, compared with infants who experience either prematurity or congenital anomalies alone.

Neuroplacentology in congenital heart disease: placental connections to neurodevelopmental outcomes

Children with congenital heart disease (CHD) are living longer due to effective medical and surgical management. However, the majority have neurodevelopmental delays or disorders. The role of the placenta in fetal brain development is unclear and is the focus of an emerging field known as neuroplacentology. In this review, we summarize neurodevelopmental outcomes in CHD and their brain imaging correlates both in utero and postnatally. We review differences in the structure and function of the placenta in pregnancies complicated by fetal CHD and introduce the concept of a placental inefficiency phenotype that occurs in severe forms of fetal CHD, characterized by a myriad of pathologies. We propose that in CHD placental dysfunction contributes to decreased fetal cerebral oxygen delivery resulting in poor brain growth, brain abnormalities, and impaired neurodevelopment. We conclude the review with key areas for future research in neuroplacentology in the fetal CHD population, including (1) differences in structure and function of the CHD placenta, (2) modifiable and nonmodifiable factors that impact the hemodynamic balance between placental and cerebral circulations, (3) interventions to improve placental function and protect brain development in utero, and (4) the role of genetic and epigenetic influences on the placenta-heart-brain connection. IMPACT: Neuroplacentology seeks to understand placental connections to fetal brain development. In fetuses with CHD, brain growth abnormalities begin in utero. Placental microstructure as well as perfusion and function are abnormal in fetal CHD.

Neurodevelopmental outcome of patients with congenital gastrointestinal malformations: a systematic review and meta-analysis

AIM

Children with congenital gastrointestinal malformations may be at risk of neurodevelopmental impairment due to challenges to the developing brain, including perioperative haemodynamic changes, exposure to anaesthetics and postoperative inflammatory influences. This study aggregates existing evidence on neurodevelopmental outcome in these patients using meta-analysis.

METHOD

PubMed, Embase and Web of Science were searched for peer-reviewed articles published until October 2019. Out of the 5316 unique articles that were identified, 47 studies met the inclusion criteria and were included. Standardised mean differences (Cohen's d) between cognitive, motor and language outcome of patients with congenital gastrointestinal malformations and normative data (39 studies) or the studies' control group (8 studies) were aggregated across studies using random-effects meta-analysis. The value of (clinical) moderators was studied using meta-regression and diagnostic subgroups were compared.

RESULTS

The 47 included studies encompassed 62 cohorts, representing 2312 patients. Children with congenital gastrointestinal malformations had small-sized cognitive impairment (d=-0.435, p<0.001; 95% CI -0.567 to -0.302), medium-sized motor impairment (d=-0.610, p<0.001; 95% CI -0.769 to -0.451) and medium-sized language impairment (d=-0.670, p<0.001; 95% CI -0.914 to -0.425). Patients with short bowel syndrome had worse motor outcome. Neurodevelopmental outcome was related to the number of surgeries and length of total hospital stay, while no relations were observed with gestational age, birth weight, age and sex.

INTERPRETATION

This study shows that children with congenital gastrointestinal malformations exhibit impairments in neurodevelopmental outcome, highlighting the need for routine screening of neurodevelopment during follow-up.

The Evolution of an Interdisciplinary Developmental Round in a Surgical Neonatal Intensive Care Unit

BACKGROUND

Developmentally supportive environments are known to improve medical outcomes for hospitalized neonates and are considered the overarching philosophy for practice in the neonatal setting. Developmental rounds are a strategy incorporated by multidisciplinary teams to support development within and beyond the neonatal unit. Typically, they consist of bedside consultations and individualized developmentally supportive recommendations for families and clinicians. Globally, the use of developmental rounds has been described since the early 1990s. They are viewed as a measure to counter some of the barriers to developmental care implementation while buffering against the effect of an intensive care admission. To date, their use in the surgical neonatal intensive care unit (sNICU) has been minimally reported in literature.

PURPOSE

This article describes the focus and work of a developmental round team and strategy in the sNICU.

METHOD

A retrospective audit of developmental round key performance criteria undertaken over a 4-year period (2015-2018).

FINDINGS/RESULTS

More than 300 developmental consults and 2000 individualized developmental recommendations occurred annually. Parental presence during the developmental round increased by 10%, from 48% to 58%, during the audit period.

IMPLICATIONS FOR PRACTICE/IMPLICATIONS FOR RESEARCH

Literature has supported the use of developmental round interventions; however, minimal data have been reported to date. This article provides retrospective audit data of a developmental round intervention in the sNICU with a focus on data over 4 years to highlight key areas, including the structure and process, recommended educational standards for team members, and parental engagement, as key markers for developmental round efficacy. Future research should focus on the link between the developmental round intervention and long-term neonatal outcomes.

Gastrostomy tube placement in neonates undergoing tracheostomy: an opportunity to coordinate care?

OBJECTIVES

To describe variations in timing of gastrostomy tube (GT) placement for neonates undergoing tracheostomy.

METHODS

Database study of neonates undergoing tracheostomy and GT placement using the Pediatric Health Information System (2012-2015). The primary outcome was timing of GT relative to tracheostomy. Logistic regression evaluated associations of patient- and hospital-level characteristics with GT timing.

RESULTS

Of 1156 patients undergoing GT and tracheostomy placement, 42.4% had concurrent GT placement, 23.3% GT placement prior to tracheostomy, and 34.3% GT placement after tracheostomy. The proportion of patients undergoing concurrent placement ranged from 0 to 80% among 47 hospitals. Neonates born at 31-35 weeks, having cardiovascular comorbidities, history of diaphragmatic hernia repair, or gastroesophageal reflux disorder were more likely to receive GT placement prior to tracheostomy.

CONCLUSION

Significant variability exists in the timing of neonatal tracheostomy and GT placement. Opportunities may exist to optimize coordination of care for neonates and reduce anesthetic exposure and hospital resource utilization.

Early Life Parechovirus Infection Neurodevelopmental Outcomes at 3 Years: A Cohort Study

OBJECTIVE

To investigate the long-term developmental and behavioral outcomes in an established cohort of children hospitalized as infants with human parechovirus (HPeV) infection and sepsis-like illness.

STUDY DESIGN

The HPeV cohort was composed of children 3 years of age after HPeV infection and hospitalization in early infancy that occurred during a well-documented HPeV genotype 3 outbreak in Australia. We assessed neurodevelopmental and behavioral outcomes using the Bayley Scales of Infant and Toddler Development-III and the Child Behavior Checklist. We compared their outcomes with a subsample of healthy control infants drawn from the independently sampled Triple B Pregnancy Cohort Study.

RESULTS

Fifty children, with a mean age of 41 months, were followed for 3 years after hospital admission with HPeV infection. There were 47 children whose original illness was fever without source or sepsis-like illness and 3 who had encephalitis. All children in the HPeV cohort showed age-specific development within the population normal range on the Bayley Scales of Infant and Toddler Development-III. There was no difference in developmental attainment compared with 107 healthy control infants after adjusting for measured confounders. The HPeV cohort showed higher average scores on the Child Behavior Checklist and a higher frequency of clinical range scores compared with healthy controls.

CONCLUSIONS

Although HPeV sepsis-like illness did not result in neurodevelopmental delay at 3 years of age, it was associated with increased behavioral problems compared with healthy controls. The behavioral problems reached a clinical threshold in a minority of children. Results inform clinical management and planning for children after severe HPeV infection in infancy.

Long-Term Neurodevelopmental Outcomes in Children with Biliary Atresia

OBJECTIVE

To assess long-term neurodevelopmental outcomes in school-aged children with biliary atresia.

STUDY DESIGN

All Dutch children (6-12 years of age) diagnosed with biliary atresia were invited to participate in this study. We used validated neurodevelopmental tests to assess motor skills and cognition, and questionnaires to assess behavior. Scores were compared with the Dutch norm population, by means of 1-sample tests. Results are given as number and percentage or mean ± SD.

RESULTS

We included 46 children, with a median age of 11 years (range, 6-13 years); 36 children had undergone a liver transplantation (78%). Twelve children (26%) received special education (vs 2.4% in the norm population; P < .01). Motor outcomes were significantly affected compared with the norm population (P < .01), with 25% normal (vs 85%), 25% borderline (vs 10%), and 50% low scores (vs 5%). Total IQ was lower in patients with biliary atresia, compared with the norm population (91 ± 18 vs 100 ± 15; P < .01). There were no significant differences in test scores between children with native liver and after liver transplantation.

CONCLUSIONS

School-aged children with biliary atresia show neurodevelopmental impairments compared with the norm population, especially in motor skills. Our data strongly warrant evaluation of neurodevelopmental intervention programs to assess whether long-term outcomes could be improved.

Early neurodevelopmental outcomes of congenital gastrointestinal surgical conditions: a single-centre retrospective study

BACKGROUND

Evidence is emerging that surgery in the neonatal period is associated with increased risk of suboptimal neurodevelopmental outcomes (SNDO). The aim of this study was to describe neurodevelopmental outcomes (at 1 year) of neonatal surgery for congenital gastrointestinal surgical conditions (CGSC) and to explore risk factors.

METHODS

Retrospective study (2005-2014) of infants born ≥34 weeks gestation with CGSC and admitted to the surgical neonatal intensive care unit of Perth Children's Hospital, Western Australia. Clinical details and 1-year developmental outcomes based on Griffiths Mental Developmental Assessment Scales were collated from the database and by reviewing the medical records of study infants. SNDO was defined as one or more of the following: a general quotient less than 88 (ie, >1 SD below mean), cerebral palsy, blindness or sensorineural deafness. Univariable and multivariable logistic regression analyses were carried out to explore risk factors for SNDO. A total of 413 infants were included, of which 13 died. Median gestation was 37.6 weeks (IQR: 36.4-39.1). Information on developmental outcomes was available from 262 out of 400 survivors. A total of 43/262 (16.4%) had SNDO. On univariable analysis, lower z scores for birth weight, prolonged duration of antibiotics, increased episodes of general anaesthesia and prolonged duration of hospital stay were associated with SNDO. On multivariable analysis, lower z scores for birth weight and prolonged hospital stay were associated with increased risk of SNDO.

CONCLUSIONS

Late preterm and term infants undergoing neonatal surgery for CGSC may be at risk for SNDO. Studies with longer duration of follow-up are needed to further evaluate the role of potentially modifiable risk factors on their neurodevelopmental outcomes.

Associations of Neonatal Noncardiac Surgery with Brain Structure and Neurodevelopment: A Prospective Case-Control Study

OBJECTIVE

To examine the associations of neonatal noncardiac surgery with newborn brain structure and neurodevelopment at 2 years of age.

STUDY DESIGN

Infants requiring neonatal noncardiac surgery for congenital diaphragmatic hernia, esophageal atresia, or anterior abdominal wall defect were compared with infants who did not require surgery, matched for sex, gestation at birth, and postmenstrual age at magnetic resonance imaging. Cerebral magnetic resonance imaging was performed at a mean (SD) postmenstrual age of 41.6 (1.7) weeks. Images were assessed qualitatively for brain maturation and injury and quantitatively for measures of brain size, cerebrospinal fluid spaces, and global abnormality. Neurodevelopment was then assessed at 2 years using the Bayley Scales of Infant and Toddler Development, 3rd edition.

RESULTS

Infants requiring surgery (n = 39) were 5.9 times (95% CI, 1.9-19.5; P < .01) more likely to have delayed gyral maturation and 9.8 times (95% CI, 1.2-446; P = .01) more likely to have white matter signal abnormalities compared with controls (n = 39). Cases were more likely to have higher global abnormality scores, smaller biparietal diameters, and larger ventricular sizes than controls. Infants who had surgery had lower mean composite scores in the language (mean difference, -12.5; 95% CI, -22.4 to -2.7) and motor domains (mean difference, -13.4; 95% CI, -21.1 to -5.6) compared with controls.

CONCLUSIONS

Infants requiring neonatal noncardiac surgery have smaller brains with more abnormalities compared with matched controls and have associated neurodevelopmental impairment at 2 years of age. Prospective studies with preoperative and postoperative imaging would assist in determining the timing of brain injury.

'Big issues' in neurodevelopment for children and adults with congenital heart disease

It is established that neurodevelopmental disability (NDD) is common in neonates undergoing complex surgery for congenital heart disease (CHD); however, the trajectory of disability over the lifetime of individuals with CHD is unknown. Several ‘big issues’ remain undetermined and further research is needed in order to optimise patient care and service delivery, to assess the efficacy of intervention strategies and to promote best outcomes in individuals of all ages with CHD. This review article discusses ‘gaps’ in our knowledge of NDD in CHD and proposes future directions.

Developmental outcome at 3 years of age of infants following surgery for infantile hypertrophic pyloric stenosis

PURPOSE

The study compared neurodevelopmental outcome at 3 years of age of infants with infantile hypertrophic pyloric stenosis (IHPS) who underwent pyloromyotomy with healthy control infants in New South Wales, Australia.

METHODS

Infants with IHPS as well as controls were recruited between August 2006 and July 2008. Developmental assessments were performed using the Bayley scales of infant and toddler development (version III) (BSITD-III) at 1 and 3 years of age.

RESULTS

Of the 43 infants originally assessed at 1 year, 39 returned for assessment at 3 years (90%). The majority were term infants (77%). Assessments were also performed on 156 control infants. Infants with IHPS scored significantly lower on four of the five Bayley subsets (cognitive, receptive and expressive language and fine motor) compared to control infants. Analysis of co-variance showed statistically significant results in favour of the control group for these four subsets.

CONCLUSION

Compared with the outcomes at 1 year, infants with IHPS at 3 years of age continue to score below controls in four of the BSITD-III subscales. This suggests they should have developmental follow-up with targeted clinical intervention. There is a need for further studies into functional impact and longer term outcomes.

School-Age Developmental and Educational Outcomes Following Cardiac Procedures in the First Year of Life: A Population-Based Record Linkage Study

The purpose of the study was to evaluate school-age developmental and educational outcomes for children with and without a cardiac procedure in the first year of life to improve understanding of longer-term neurodevelopmental outcomes in children who have had a cardiac procedure for congenital heart disease, the most common serious congenital anomaly. A population-based cohort study using record linkage of state-wide data was undertaken, evaluating children born in New South Wales, Australia, 2001-2007. Those with and without a cardiac procedure in the first year of life with a linked developmental (Australian version Early Development Instrument testing result, age 4-6 years) and/or educational outcome (Australian National Assessment Program result, age 7-9 years) were included. Perinatal, perioperative and sociodemographic factors were examined using multivariable logistic regression models. Of 468,329 eligible children, 768 had a cardiac procedure in the first year of life and 582 were included. For those with a cardiac procedure and developmental outcome (n = 260), 13.1% were classified as having 'special needs' compared to 4.4% without a cardiac procedure. Of those with an educational outcome, after adjusting for perinatal, perioperative and demographic variables, children with a cardiac procedure (n = 396) were twice as likely to score below National Minimum Standard in school literacy and numeracy tests compared to their peers. Significant predictors included low birthweight, parent not completing school and having > 4 re-hospitalisations in their first six years. The developmental and educational trajectory of children who have had a cardiac procedure in their first year remains altered into primary school years. While perioperative factors did not impact outcomes, ongoing health and sociodemographic factors were important in identifying those children at greatest risk.

Omphalocele: from diagnosis to growth and development at 2 years of age

OBJECTIVES

To 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.

DESIGN

We 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.

RESULTS

We 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).

CONCLUSIONS

The 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.

Prediction of three year outcomes using the Bayley-III for surgical, cardiac and healthy Australian infants at one year of age

BACKGROUND

Previous predictive research has predominantly focussed on infants who are preterm, low birth weight, who have a specific condition or who have undergone a specific procedure.

AIM

This study investigated the ability of outcomes at one year of age to predict outcomes at three years using the Bayley-III for infants who have undergone early major cardiac surgery (CS) or non-cardiac (NC) surgery and their healthy peers.

STUDY DESIGN

Participants who were part of the Development After Infant Surgery (DAISy) study who had complete Bayley-III assessments at one and three years of age were included in the analyses. This included 103 infants who had undergone CS, 158 who had NC surgery and 160 controls.

RESULTS

Bayley-III outcomes at one, although statistically significantly associated with three year outcomes in all domains were weak predictors of those outcomes for CS, NC surgical and healthy infants. Specificity for three year outcomes was good for cognitive, receptive language and fine motor domains for infants who had undergone CS and NC surgery. Sensitivity for <-1 SD at three years was poor for cognitive, expressive and receptive language, and fine motor outcomes for CS and NC surgical participants.

CONCLUSION

It remains difficult to predict how performance at one year on the Bayley-IIII predicts performance at three on the Bayley-III for infants who have undergone early major CS or NC surgery and for healthy Australian infants.

Neonatal Morbidity at Term, Early Child Development, and School Performance: A Population Study

OBJECTIVES

Investigate the association between severe neonatal morbidity (SNM) and child development and school performance among term infants.

METHODS

The study population included term infants without major congenital conditions born between 2000 and 2007 in New South Wales, Australia, with a linked record of developmental assessment at ages 4 to 6 years in 2009 or 2012 (n = 144 535) or school performance at ages 7 to 9 years from 2009 to 2014 (n = 253 447). Developmental outcomes included special needs or being vulnerable and/or at risk in 1 of 5 developmental domains. School performance outcomes were test exemption, or performing <-1 SD on reading or numeracy tests. Binary generalized estimating equations were used to estimate associations between SNM and outcomes, adjusting for sociodemographic, perinatal, and assessment and/or test characteristics.

RESULTS

Overall, 2.1% of infants experienced SNM. The adjusted odds ratio (95% confidence interval) for SNM and physical health was 1.18 (1.08-1.29), 1.14 (1.02-1.26) for language and cognitive skills, and 1.14 (1.06-1.24) and 1.13 (1.05-1.21) for scoring <-1 SD in reading and numeracy, respectively. SNM was most strongly associated with special needs 1.34 (1.15-1.55) and test exemption 1.50 (1.25-1.81). SNM infants born at 37 to 38 weeks' gestation and who were small for gestational age had the greatest likelihood of poorer outcomes.

CONCLUSIONS

Term infants with SNM have greater odds of poor neurodevelopment in childhood. These findings provide population-based information for families and can inform clinical counseling and guidelines for follow-up and early intervention.

Developmental outcomes and physical activity behaviour in children post major surgery: an observational study

Background

Infants may be at neurodevelopmental risk from adverse events arising in the neonatal period. This study aimed to investigate the developmental outcomes and physical activity behaviours of term infants after neonatal major surgery, at age three years.

Methods

This prospective study enrolled infants who underwent major surgery in their first 90 days, between August 2006 and December 2008. Developmental status was assessed using the Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III). Physical activity and sedentary behaviour (i.e. small screen recreation) (SSR) were assessed using the Preschool-Age Physical Activity Questionnaire (Pre-PAQ). Activity (moving between slow to fast pace) and SSR were reported for a 3-day period.

Results

One hundred and thirty five children (68 major surgery, 67 control) were assessed, using both measures, at age three years. Both groups were within the average range across all domains of the BSID-III although the surgical group was significantly below the controls for cognition (t = −3.162, p = 0.002) receptive language (t = −3.790, p < 0.001) and fine motor skills (t = −2.153, p = 0.03). Mean activity time for the surgical group was 191 mins.day⁻¹, and 185 mins.day-1 for controls. Mean SSR time was 77 mins.day⁻¹, and 83 mins.day⁻¹ for the respective groups. There was no significant difference between groups for either physical activity (p = 0.71) or SSR time (p = 0.49).

Conclusions

By age three, children who had major surgery in infancy are developmentally normal but have not quite caught up with their peer group in cognitive, receptive language and fine motor skill domains.

Developmental outcomes at three years of age of infants with esophageal atresia

BACKGROUND/AIMS

Previous work assessing early developmental outcomes of infants at one year of age following surgery for esophageal atresia (OA) and/or tracheoesophageal fistula (TOF) found a significantly lower score in expressive language compared with control infants. The purpose of this study was to determine whether these differences were still evident at three years of age.

METHODS

Between August 2006 and July 2008, infants who required surgical correction of OA/TOF were prospectively enrolled as part of a large study which examined developmental outcomes following surgery. Patients were reassessed using the Bayley Scales of Infant and Toddler Development Version III. Cognition, expressive and receptive language, fine motor and gross motor skills scores were compared with both the standardized norms and also with contemporaneous control infants.

RESULTS

24 of the 31 infants (77%) assessed at one year were reassessed at three years of age. There was no significant difference between the Bayley scores of the infants with OA/TOF and the standardized norms of the tests in four of the subsets: cognition, expressive language, fine and gross motor skills. Infants with OA scored higher than normative values for the receptive language subscale (P=0.001). When compared with the controls, there were no significant differences in any of the subscales.

CONCLUSION

Compared with the outcomes at one year, infants with OA/TOF have improved and were scoring within the normal range for the assessment at three years. This may in part be because of the early intervention services which many of these children were provided.
