Abstract
Over the past decades, music therapy in the neonatal intensive care unit (NICU) has been proven effective in physiological and psychological outcomes, including sucking, behaviour, stress reduction, neurodevelopment and promoting emotional bonding. However, not every NICU administers music therapy in their ward. Research on music therapy for neonates and their caregivers has lately accumulated, increasing the evidence of health benefits on brain development and across a variety of NICU-related pathologies, including neurological, cardiological, pulmonary and gastrointestinal problems. Conclusively, we will present the studied methods of music therapy for clinical benefits in neonatal intensive care.

Wang LW, Chu CH, Lin YC, Huang CC. Severe brain injury and trends of gestational-age-related neurodevelopmental outcomes in infants born very preterm: A population cohort study. Dev Med Child Neurol 2024. [PMID: 38946133 DOI: 10.1111/dmcn.16003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/03/2023] [Revised: 05/15/2024] [Accepted: 05/22/2024] [Indexed: 07/02/2024]
Abstract
AIM To investigate the impact of severe neonatal brain injury (SNBI) on gestational age-related trends in neurodevelopmental impairment (NDI) outcome in infants born very preterm. METHOD A population-based cohort study recruited 1091 infants born at a gestational age of less than 31 weeks between 2011 and 2020. The trends in neonatal morbidities, mortality, and 24-month NDI severity (no/mild, moderate, severe) by epoch (2011-2015, 2016-2020) and gestational age (22-25 weeks, 26-28 weeks, 29-30 weeks) were determined in infants with and without SNBI inclusion. RESULTS There was increased antenatal steroid use and higher maternal education and socioeconomic status over time. The rates of neonatal morbidities and mortality had no temporal changes. Among 825 infants with follow-up, those in the 22 to 25 weeks gestational age group had declining trends in cerebral palsy and severe cognitive impairment, with decreased rates of severe NDI from 19% to 8% across epochs, particularly in those without SNBI (from 16% to 2%). Relative to its occurrence in epoch 2011 to 2015, risk of severe NDI was significantly reduced in epoch 2016 to 2020 (adjusted relative risk 0.39, 95% confidence interval 0.16-0.96) for infants born at 22 to 25 weeks gestational age, and the risk dropped even lower in these infants without SNBI (0.12, 0.02-0.84). INTERPRETATION Infants born at 22 to 25 weeks gestational age had decreased rates of severe NDI in the decade between 2011 and 2020, particularly those without SNBI. The improvement might be attributed to better perinatal/neonatal and after-discharge care.

Abstract
OBJECTIVE To evaluate the growth trajectory of head circumference and neurodevelopment, and to correlate head circumference with cognitive, language, and motor outcomes during the first two years. METHOD Prospective cohort study in a tertiary hospital including 95 newborns under 32 weeks or 1500 g. Neonates who developed major neonatal morbidities were excluded. The head circumference was measured at birth, at discharge, and at term-equivalent age, 1, 3, 5, 12, 18, and 24 months of corrected age, and the Bayley Scales (Bayley-III) were applied at 12, 18 and 24 months of corrected age to assess cognitive, language and, motor domains. Scores below 85 were classified as mild/moderate deficits and scores below 70 as severe deficits. The association between head circumference Z score and Bayley scores was assessed using Pearson's correlation. The study considered a significance level of 0.05. RESULTS There was a decrease of -0.18 in the head circumference Z score between birth and discharge and the catch-up occurred between discharge and 1 month (an increase of 0.81 in the Z score). There was a positive correlation between head circumference and Bayley scores at 18 months. There was also a positive correlation between head circumference at discharge and at 5 months with the three domains of the Bayley. CONCLUSION Serial measurements of head circumference provide knowledge of the trajectory of growth, with early catch-up between discharge and 1 month, as well as its association with neurodevelopment. Head circumference is therefore a valuable clinical marker for neurodevelopment, especially in very preterm newborns.

Abstract
OBJECTIVE To evaluate whether white matter injury (WMI) volumes and spatial distribution, which are important predictors of neurodevelopmental outcomes in preterm infants, have changed over a period of 15 years. STUDY DESIGN Five hundred and twenty-eight infants born <32 weeks' gestational age from 2 sequential prospective cohorts (cohort 1: 2006 through 2012; cohort 2: 2014 through 2019) underwent early-life (median 32.7 weeks postmenstrual age) and/or term-equivalent-age MRI (median 40.7 weeks postmenstrual age). WMI were manually segmented for quantification of volumes. There were 152 infants with WMI with 74 infants in cohort 1 and 78 in cohort 2. Multivariable linear regression models examined change in WMI volume across cohorts while adjusting for clinical confounders. Lesion maps assessed change in WMI location across cohorts. RESULTS There was a decrease in WMI volume in cohort 2 compared with cohort 1 (β = -0.6, 95% CI [-0.8, -0.3], P < .001) with a shift from more central to posterior location of WMI. There was a decrease in clinical illness severity of infants across cohorts. CONCLUSIONS We found a decrease in WMI volume and shift to more posterior location in very preterm infants over a period of 15 years. This may potentially reflect more advanced maturation of white matter at the time of injury which may be related to changes in clinical practice over time.

Abstract
Adverse perinatal factors can interfere with the normal development of the brain, potentially resulting in long-term effects on the comprehensive development of children. Presently, the understanding of cognitive and neurodevelopmental processes under conditions of adverse perinatal factors is substantially limited. There is a critical need for an open resource that integrates various perinatal factors with the development of the brain and mental health to facilitate a deeper understanding of these developmental trajectories. In this Data Descriptor, we introduce a multicenter database containing information on perinatal factors that can potentially influence children's brain-mind development, namely, periCBD, that combines neuroimaging and behavioural phenotypes with perinatal factors at county/region/central district hospitals. PeriCBD was designed to establish a platform for the investigation of individual differences in brain-mind development associated with perinatal factors among children aged 3-10 years. Ultimately, our goal is to help understand how different adverse perinatal factors specifically impact cognitive development and neurodevelopment. Herein, we provide a systematic overview of the data acquisition/cleaning/quality control/sharing, processes of periCBD.

Abstract
OBJECTIVE To evaluate changes in prevalence and severity of cerebral palsy (CP) among surviving children born at <27 weeks of gestation over time and to determine associations between CP and other developmental domains, functional impairment, medical morbidities, and resource use among 2-year-old children who were born extremely preterm. STUDY DESIGN Retrospective cohort study using prospective registry data, conducted at 25 centers of the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network. Participants were children born at <27 weeks of gestation and followed at 18 through 26 months of corrected age from 2008 through 2019. Outcomes of interest were changes in prevalence of any CP and severity of CP over time and associations between CP and other neurodevelopmental outcomes, functional impairment, and medical comorbidities. Adjusted logistic, linear, multinomial logistic, and robust Poisson regression evaluated the relationships between child characteristics, CP severity, and outcomes. RESULTS Among 6927 surviving children with complete follow-up data, 3717 (53.7%) had normal neurologic examinations, 1303 (18.8%) had CP, and the remainder had abnormal neurologic examinations not classified as CP. Adjusted rates of any CP increased each year of the study period (aOR 1.11 per year, 95% CI 1.08-1.14). Cognitive development was significantly associated with severity of CP. Children with CP were more likely to have multiple medical comorbidities, neurosensory problems, and poor growth at follow-up. CONCLUSIONS The rate of CP among surviving children who were born extremely preterm increased from 2008 through 2019. At 18 to 26 months of corrected age, neurodevelopmental and medical comorbidities are strongly associated with all severity levels of CP.

Parent screening questionnaires to detect cognitive and language delay at 2 years in high-risk infants: an analysis from the Victorian Infant Collaborative Study 2016-2017 cohort. Arch Dis Child Fetal Neonatal Ed 2024:fetalneonatal-2023-326618. [PMID: 38604647 DOI: 10.1136/archdischild-2023-326618] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Accepted: 03/24/2024] [Indexed: 04/13/2024]
Abstract
OBJECTIVE To determine the accuracy of two developmental screening questionnaires to detect cognitive or language delay, defined using the Bayley Scales of Infant and Toddler Development-Third Edition (Bayley-III), in children born extremely preterm (EP: <28 weeks' gestation) or extremely low birth weight (ELBW: <1000 g). DESIGN Prospective cohort study. SETTING State of Victoria, Australia. PATIENTS 211 infants born EP/ELBW assessed at 2 years' corrected age (mean 2.2, SD 0.2). MAIN OUTCOME MEASURES Cognitive and language delay (<-1 SD) on the Bayley-III. The screening questionnaires were the Parent Report of Children's Abilities-Revised (PARCA-R) and the Ages & Stages Questionnaires Third Edition (ASQ-3). RESULTS The PARCA-R performed better than the ASQ-3, but neither questionnaire had substantial agreement with the Bayley-III to detect cognitive delay; kappa (95% CI): PARCA-R 0.43 (0.23, 0.63); ASQ-3 0.15 (-0.05, 0.35); sensitivity (95% CI): PARCA-R 70% (53%, 84%) ASQ-3 62% (47%, 76%); specificity (95% CI): PARCA-R 73% (60%, 84%) ASQ-3 53% (38%, 68%). When both tools were used in combination (below cut-off on at least one assessment), sensitivity increased to 78% (60%, 91%) but specificity fell to 45% (29%, 62%). Similar trends were noted for language delay on the Bayley-III, although kappa values were better than for cognitive delay. CONCLUSIONS Neither screening questionnaire identified cognitive delay well, but both were better at identifying language delay. The PARCA-R detects delay on the Bayley-III more accurately than the ASQ-3. Sensitivity for detecting delay is greatest when the PARCA-R and ASQ-3 were used in combination, but resulted in lower specificity.

Abstract
AIM The architecture of neonatal units plays a key role in developmental strategies and preterm outcomes. The aim was to evaluate the design of Spanish neonatal units and its impact on the participation of parents in neonatal care. METHODS A web-based survey was sent to all level III Spanish neonatal units, including questions about hospital data, architectural design, facilities and family participation. RESULTS The study included 63 units. Most units (87%) had part or all the intensive care patients located in open bay units, while 54% had at least one individual patient cubicle. Single family rooms, defined as those including enough space and furniture for family members to stay with the infant without restrictions, were available in 8 units (13%). Eighteen units (29%) had a structured programme of family education. Units with single family rooms were more likely to have parental participation in rounds (p < 0.01), safety protocols (p = 0.02), oxygen management (p < 0.01) and nasogastric tube feeding (p = 0.02), as well as to allow siblings to participate in kangaroo care (p < 0.01). CONCLUSION Widely variable architectural designs and policies were found in Spanish neonatal units. The presence of single family rooms may have impacted the participation of parents in neonatal care.

Abstract
The survival of preterm infants has steadily improved thanks to advances in perinatal and neonatal intensive clinical care. The focus is now on finding ways to improve morbidities, especially neurological outcomes. Although antenatal steroids and magnesium for preterm infants have become routine therapies, studies have mainly demonstrated short-term benefits for antenatal steroid therapy but limited evidence for impact on long-term neurodevelopmental outcomes. Further advances in neuroprotective and neurorestorative therapies, improved neuromonitoring modalities to optimize recruitment in trials, and improved biomarkers to assess the response to treatment are essential. Among the most promising agents, multipotential stem cells, immunomodulation, and anti-inflammatory therapies can improve neural outcomes in preclinical studies and are the subject of considerable ongoing research. In the meantime, bundles of care protecting and nurturing the brain in the neonatal intensive care unit and beyond should be widely implemented in an effort to limit injury and promote neuroplasticity. IMPACT: With improved survival of preterm infants due to improved antenatal and neonatal care, our focus must now be to improve long-term neurological and neurodevelopmental outcomes. This review details the multifactorial pathogenesis of preterm brain injury and neuroprotective strategies in use at present, including antenatal care, seizure management and non-pharmacological NICU care. We discuss treatment strategies that are being evaluated as potential interventions to improve the neurodevelopmental outcomes of infants born prematurely.

[PMID: 38503935 DOI: 10.1007/s00455-024-10683-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Accepted: 02/02/2024] [Indexed: 03/21/2024]
Abstract
Feeding/swallowing and airway protection are complex functions, essential for survival, and continue to evolve throughout the lifetime. Medical and surgical advances across the globe have improved the long-term survival of medically complex children at the cost of increasing comorbidities, including dysfunctional swallowing (dysphagia). Dysphagia is prominent in children with histories of preterm birth, neurologic and neuromuscular diagnoses, developmental delays, and aerodigestive disorders; and is associated with medical, health, and neurodevelopmental problems; and long-term socioeconomic, caregiver, health system, and social burdens. Despite these survival and population trends, data on global prevalence of childhood dysphagia and associated burdens are limited, and practice variations are common. This article reviews current global population and resource-dependent influences on current trends for children with dysphagia, disparities in the availability and access to specialized multidisciplinary care, and potential impacts on burdens. A patient example will illustrate some questions to be considered and decision-making options in relation to age and development, availability and accessibility to resources, as well as diverse cultures and family values. Precise recognition of feeding/swallowing disorders and follow-up intervention are enhanced by awareness and knowledge of global disparities in resources. Initiatives are needed, which address geographic and economic barriers to providing optimal care to children with dysphagia.

Abstract
INTRODUCTION Severe brain injury (SBI), including severe intraventricular haemorrhage (sIVH) and cystic periventricular leukomalacia, poses significant challenges for preterm infants, yet recent data and trends are limited. METHODS Analyses were conducted using the Australian and New Zealand Neonatal Network data on preterm infants born <32 weeks' gestation admitted at Monash Children's Hospital, Australia, from January 2014 to April 2021. The occurrence and trends of SBI and sIVH among preterm infants, along with the rates and trends of death and neurodevelopmental impairment (NDI) in SBI infants were assessed. RESULTS Of 1,609 preterm infants, 6.7% had SBI, and 5.6% exhibited sIVH. A total of 37.6% of infants with SBI did not survive to discharge, with 92% of these deaths occurring following redirection of clinical care. Cerebral palsy was diagnosed in 65.2% of SBI survivors, while 86.4% of SBI survivors experienced NDI. No statistically significant differences were observed in the temporal trends of SBI (adjusted OR [95% CI] 1.08 [0.97-1.20]; p = 0.13) or sIVH (adjusted OR [95% CI] 1.09 [0.97-1.21]; p = 0.11). Similarly, there was no statistically significant difference noted in the temporal trend of the composite outcome, which included death or NDI among infants with SBI (adjusted OR [95% CI] 0.90 [0.53-1.53]; p = 0.71). CONCLUSION Neither the rates of SBI nor its associated composite outcome of death or NDI improved over time. A notable proportion of preterm infants with SBI faced redirection of care and subsequent mortality, while most survivors exhibited adverse neurodevelopmental challenges. The development of better therapeutic interventions is imperative to improve outcomes for these vulnerable infants.

Abstract
AIM The current study determined the neurodevelopmental outcome of extremely preterm infants at 2 years of age. METHODS All live-born infants 23-27 weeks of gestation born between 2011 and 2020 in Austria were included in a prospective registry. Neurodevelopmental outcome at 2 years of corrected age was assessed using Bayley Scales of Infant Development for both motor and cognitive scores, along with a neurological examination and an assessment of neurosensory function. RESULTS 2378 out of 2905 (81.9%) live-born infants survived to 2 years of corrected age. Follow-up data were available for 1488 children (62.6%). Overall, 43.0% had no, 35.0% mild and 22.0% moderate-to-severe impairment. The percentage of children with moderate-to-severe neurodevelopmental impairment decreased with increasing gestational age and was 31.4%, 30.5%, 23.3%, 19.0% and 16.5% at 23, 24, 25, 26 and 27 weeks gestational age (p < 0.001). Results did not change over the 10-year period. In multivariate analysis, neonatal complications as well as male sex were significantly associated with an increased risk of neurodevelopmental impairment. CONCLUSION In this cohort study, a 22.0% rate of moderate-to-severe neurodevelopmental impairment was observed among children born extremely preterm. This national data is important for both counselling parents and guiding the allocation of health resources.

Abstract
This paper describes the development and justification of a qualitative methodology aimed at exploring the infant's personal experience of hospitalisation in the neonatal intensive care unit (NICU). We begin by briefly reviewing existing methods for documenting and recording infant experiences. These methods focus on the clinical needs of the infant predominantly through quantifiable medical outcome data. Research understanding their experience of receiving clinical care is lacking. By exploring newborn infant behaviour, cues, and communication strategies we assert the infant as a capable participant in neonatal research. We then describe the methodology and methods which we have named 360-degree phenomenology that draws directly from the capabilities and knowledge of the infants themselves. We propose this methodology will address the gap in the literature by enabling a rich and comprehensive overview of the early life experiences of infants hospitalised in NICU.

Abstract
Despite providing intensive care to more infants born <24 weeks' gestation, data on school-age outcomes, critical for counselling and decision-making, are sparse. OBJECTIVE To compare major neurosensory, cognitive and academic impairment among school-aged children born extremely preterm at 22-23 weeks' gestation (EP22-23) with those born 24-25 weeks (EP24-25), 26-27 weeks (EP26-27) and term (≥37 weeks). DESIGN Three prospective longitudinal cohorts. SETTING Victoria, Australia. PARTICIPANTS All EP live births (22-27 weeks) and term-born controls born in 1991-1992, 1997 and 2005. MAIN OUTCOME MEASURES At 8 years, major neurosensory disability (any of moderate/severe cerebral palsy, IQ <-2 SD relative to controls, blindness or deafness), motor, cognitive and academic impairment, executive dysfunction and poor health utility. Risk ratios (RRs) and risk differences between EP22-23 (reference) and other gestational age groups were estimated using generalised linear models, adjusted for era of birth, social risk and multiple birth. RESULTS The risk of major neurosensory disability was higher for EP22-23 (n=21) than more mature groups (168 EP24-25; 312 EP26-27; 576 term), with increasing magnitude of difference as the gestation increased (adjusted RR (95% CI) compared with EP24-25: 1.39 (0.70 to 2.76), p=0.35; EP26-27: 1.85 (0.95 to 3.61), p=0.07; term: 13.9 (5.75 to 33.7), p<0.001). Similar trends were seen with other outcomes. Two-thirds of EP22-23 survivors were free of major neurosensory disability. CONCLUSIONS Although children born EP22-23 experienced higher rates of disability and impairment at 8 years than children born more maturely, many were free of major neurosensory disability. These data support providing active care to infants born EP22-23.

Abstract
BACKGROUND Infants born preterm are at increased risk of cognitive and motor impairments compared with infants born at term. Early developmental interventions for preterm infants are targeted at the infant or the parent-infant relationship, or both, and may focus on different aspects of early development. They aim to improve developmental outcomes for these infants, but the long-term benefits remain unclear. This is an update of a Cochrane review first published in 2007 and updated in 2012 and 2015. OBJECTIVES Primary objective To assess the effect of early developmental interventions compared with standard care in prevention of motor or cognitive impairment for preterm infants in infancy (zero to < three years), preschool age (three to < five years), and school age (five to < 18 years). Secondary objective To assess the effect of early developmental interventions compared with standard care on motor or cognitive impairment for subgroups of preterm infants, including groups based on gestational age, birthweight, brain injury, timing or focus of intervention and study quality. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO and trial registries in July 2023. We cross-referenced relevant literature, including identified trials and existing review articles. SELECTION CRITERIA Studies included randomised, quasi-randomised controlled trials (RCTs) or cluster-randomised trials of early developmental intervention programmes that began within the first 12 months of life for infants born before 37 weeks' gestational age (GA). Interventions could commence as an inpatient but had to include a post discharge component for inclusion in this review. Outcome measures were not prespecified, other than that they had to assess cognitive outcomes, motor outcomes or both. The control groups in the studies could receive standard care that would normally be provided. DATA COLLECTION AND ANALYSIS Data were extracted from the included studies regarding study and participant characteristics, timing and focus of interventions and cognitive and motor outcomes. Meta-analysis using RevMan was carried out to determine the effects of early developmental interventions at each age range: infancy (zero to < three years), preschool age (three to < five years) and school age (five to < 18 years) on cognitive and motor outcomes. Subgroup analyses focused on GA, birthweight, brain injury, time of commencement of the intervention, focus of the intervention and study quality. We used standard methodological procedures expected by Cochrane to collect data and evaluate bias. We used the GRADE approach to assess the certainty of evidence. MAIN RESULTS Forty-four studies met the inclusion criteria (5051 randomly assigned participants). There were 19 new studies identified in this update (600 participants) and a further 17 studies awaiting outcomes. Three previously included studies had new data. There was variability in the focus and intensity of the interventions, participant characteristics, and length of follow-up. All included studies were either single or multicentre trials and the number of participants varied from fewer than 20 to up to 915 in one study. The trials included in this review were mainly undertaken in middle- or high-income countries. The majority of studies commenced in the hospital, with fewer commencing once the infant was home. The focus of the intervention programmes for new included studies was increasingly targeted at both the infant and the parent-infant relationship. The intensity and dosages of interventions varied between studies, which is important when considering the applicability of any programme in a clinical setting. Meta-analysis demonstrated that early developmental intervention may improve cognitive outcomes in infancy (developmental quotient (DQ): standardised mean difference (SMD) 0.27 standard deviations (SDs), 95% confidence interval (CI) 0.15 to 0.40; P < 0.001; 25 studies; 3132 participants, low-certainty evidence), and improves cognitive outcomes at preschool age (intelligence quotient (IQ); SMD 0.39 SD, 95% CI 0.29 to 0.50; P < 0.001; 9 studies; 1524 participants, high-certainty evidence). However, early developmental intervention may not improve cognitive outcomes at school age (IQ: SMD 0.16 SD, 95% CI -0.06 to 0.38; P = 0.15; 6 studies; 1453 participants, low-certainty evidence). Heterogeneity between studies for cognitive outcomes in infancy and preschool age was moderate and at school age was substantial. Regarding motor function, meta-analysis of 23 studies showed that early developmental interventions may improve motor outcomes in infancy (motor scale DQ: SMD 0.12 SD, 95% CI 0.04 to 0.19; P = 0.003; 23 studies; 2737 participants, low-certainty evidence). At preschool age, the intervention probably did not improve motor outcomes (motor scale: SMD 0.08 SD, 95% CI -0.16 to 0.32; P = 0.53; 3 studies; 264 participants, moderate-certainty evidence). The evidence at school age for both continuous (motor scale: SMD -0.06 SD, 95% CI -0.31 to 0.18; P = 0.61; three studies; 265 participants, low-certainty evidence) and dichotomous outcome measures (low score on Movement Assessment Battery for Children (ABC) : RR 1.04, 95% CI 0.82 to 1.32; P = 0.74; 3 studies; 413 participants, low-certainty evidence) suggests that intervention may not improve motor outcome. The main source of bias was performance bias, where there was a lack of blinding of participants and personnel, which was unavoidable in this type of intervention study. Other biases in some studies included attrition bias where the outcome data were incomplete, and inadequate allocation concealment or selection bias. The GRADE assessment identified a lower certainty of evidence in the cognitive and motor outcomes at school age. Cognitive outcomes at preschool age demonstrated a high certainty due to more consistency and a larger treatment effect. AUTHORS' CONCLUSIONS Early developmental intervention programmes for preterm infants probably improve cognitive and motor outcomes during infancy (low-certainty evidence) while, at preschool age, intervention is shown to improve cognitive outcomes (high-certainty evidence). Considerable heterogeneity exists between studies due to variations in aspects of the intervention programmes, the population and outcome measures utilised. Further research is needed to determine which types of early developmental interventions are most effective in improving cognitive and motor outcomes, and in particular to discern whether there is a longer-term benefit from these programmes.

Abstract
BACKGROUND Very preterm infants are at elevated risk for neurodevelopmental delays. Earlier prediction of delays allows timelier intervention and improved outcomes. Machine learning (ML) was used to predict mental and psychomotor delay at 25 months. METHODS We applied RandomForest classifier to data from 1109 very preterm infants recruited over 20 years. ML selected key predictors from 52 perinatal and 16 longitudinal variables (1-22 mo assessments). SHapley Additive exPlanations provided model interpretability. RESULTS Balanced accuracy with perinatal variables was 62%/61% (mental/psychomotor). Top predictors of mental and psychomotor delay overlapped and included: birth year, days in hospital, antenatal MgSO4, days intubated, birth weight, abnormal cranial ultrasound, gestational age, mom's age and education, and intrauterine growth restriction. Highest balanced accuracy was achieved with 19-month follow-up scores and perinatal variables (72%/73%). CONCLUSIONS Combining perinatal and longitudinal data, ML modeling predicted 24 month mental/psychomotor delay in very preterm infants ½ year early, allowing intervention to start that much sooner. Modeling using only perinatal features fell short of clinical application. Birth year's importance reflected a linear decline in predicting delay as birth year became more recent. IMPACT Combining perinatal and longitudinal data, ML modeling was able to predict 24 month mental/psychomotor delay in very preterm infants ½ year early (25% of their lives) potentially advancing implementation of intervention services. Although cognitive/verbal and fine/gross motor delays require separate interventions, in very preterm infants there is substantial overlap in the risk factors that can be used to predict these delays. Birth year has an important effect on ML prediction of delay in very preterm infants, with those born more recently (1989-2009) being increasing less likely to be delayed, perhaps reflecting advances in medical practice.

J Bone Miner Res 2023; 38:1800-1808. [PMID: 37850817 PMCID: PMC10946901 DOI: 10.1002/jbmr.4926] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Revised: 08/28/2023] [Accepted: 10/13/2023] [Indexed: 10/19/2023]
Abstract
The long-term bone health of young adults born extremely preterm (EP; <28 weeks' gestation) or extremely low birth weight (ELBW; <1000 g birth weight) in the post-surfactant era (since the early 1990s) is unclear. This study investigated their bone structure and estimated bone strength using peripheral quantitative computed tomography (pQCT)-based finite element modeling (pQCT-FEM). Results using this technique have been associated with bone fragility in several clinical settings. Participants comprised 161 EP/ELBW survivors (46.0% male) and 122 contemporaneous term-born (44.3% male), normal birth weight controls born in Victoria, Australia, during 1991-1992. At age 25 years, participants underwent pQCT at 4% and 66% of tibia and radius length, which was analyzed using pQCT-FEM. Groups were compared using linear regression and adjusted for height and weight. An interaction term between group and sex was added to assess group differences between sexes. Parameters measured included compressive stiffness (kcomp ), torsional stiffness (ktorsion ), and bending stiffness (kbend ). EP/ELBW survivors were shorter than the controls, but their weights were similar. Several unadjusted tibial pQCT-FEM parameters were lower in the EP/ELBW group. Height- and weight-adjusted ktorsion at 66% tibia remained lower in EP/ELBW (mean difference [95% confidence interval] -180 [-352, -8] Nm/deg). The evidence for group differences in ktorsion and kbend at 66% tibia was stronger among males than females (pinteractions <0.05). There was little evidence for group differences in adjusted radial models. Lower height- and weight-adjusted pQCT-FEM measures in EP/ELBW compared with controls suggest a clinically relevant increase in predicted long-term fracture risk in EP/ELBW survivors, particularly males. Future pQCT-FEM studies should utilize the tibial pQCT images because of the greater variability in the radius possibly related to lower measurement precision. © 2023 The Authors.

Abstract
As the first extra-uterine setting for hospitalized infants, the neonatal intensive care unit (NICU) environment can make a lasting impact on their long-term neurodevelopment. This impact is likely mediated through both specific characteristics of the physical design of the care environment, as well as the experiences that occur within this environment. Recent studies document many established benefits of single-family rooms (SFRs). However, there is concern that infants who spend a prolonged time in SFRs without their parents being intimately involved in their care have reduced opportunities for meaningful experiences, with possible adverse consequences. The purpose of this report is to share an example of an application of the family-centered developmental care model through a hybrid NICU design, inclusive of both SFRs and semi-private bays. In this paper, we empirically describe the physical and operational considerations of a hybrid model, outline the strengths and challenges of this approach, and discuss implications for patients, families, and professionals.

Abstract
BACKGROUND Our previous strain-specific systematic review (SR) showed that Lactobacillus reuteri (LR) DSM 17938 reduces necrotizing enterocolitis (NEC), late-onset sepsis (LOS), and time to full feeds (TFF) in preterm infants. Considering progress in the field over the past 6 years, we aimed to update our SR. METHODS SR of randomized controlled trials (RCTs) and non-RCTs was conducted. MEDLINE, Embase, Emcare, Cochrane CENTRAL, and gray literature were searched in June 2023. Primary outcomes were TFF, NEC stage ≥II, LOS, and all-cause mortality. Meta-analysis was performed using random-effects model. Certainty of evidence (CoE) was summarized using Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) guidelines. Trial sequential analysis (TSA) was applied for outcome of NEC in RCTs. RESULTS Twelve RCTs (n = 2284) and four non-RCTs (n = 1616) were included. Six RCTs and three non-RCTs were new. Meta-analysis of RCTs showed LR significantly reduced TFF (mean difference, -2.70 [95% CI, -4.90 to -1.31] days; P = 0.0001), NEC stage ≥II (risk ratio [RR], 0.57 [95% CI, 0.37-0.87]; P = 0.009; eight RCTs), and LOS (RR, 0.72 [95% CI, 0.54-0.97]; P = 0.03); but not mortality (RR, 0.76 [95% CI, 0.54-1.06]; P = 0.10). TSA showed diversity-adjusted required information size (DARIS) as 3624 for NEC. Overall CoE was "very low." Meta-analysis of non-RCTs showed LR reduced NEC (odds ratio, 0.34 [95% CI, 0.15-0.77]; P = 0.01) but not LOS. LR had no adverse effects. CONCLUSIONS Very low CoE suggests that LR DSM 17938 may reduce NEC and LOS and shorten TFF in preterm infants. Additional RCTs are required to confirm our findings.

Abstract
OBJECTIVE To investigate whether gestational age (GA)-related intelligence outcomes of children born very preterm improved over time. STUDY DESIGN A multicenter cohort study recruited 4717 infants born at GA <31 weeks and admitted to neonatal intensive care units between 2001 and 2015 in Taiwan. Intelligence outcomes at age 5.5 years were classified by intelligent quotient (IQ) into no cognitive impairment (IQ > -1 SD), mild cognitive impairment (IQ = -1∼-2 SD), and moderate/severe cognitive impairment (IQ < -2 SD). Trends were assessed for neonatal morbidities, mortality, and intelligence outcomes by birth epoch (2001-2003, 2004-2006, 2007-2009, 2010-2012, 2013-2015) and GA (23-24, 25-26, 27-28, 29-30 weeks). RESULTS Maternal education levels increased and rates of brain injury and mortality decreased over time. Among the 2606 children who received IQ tests, the rates of no, mild, and moderate/severe cognitive impairment were 54.5%, 30.5%, and 15.0%, respectively. There were significant trends in the increasing rates of no cognitive impairment and declining rates of mild and moderate/severe cognitive impairment in all GA groups across the 5 birth epochs. Relative to the occurrence in 2001-2003, the odds were significantly reduced for moderate/severe cognitive impairment from 2007-2009 (aOR 0.49, 95% CI 0.30-0.81) to 2013-2015 (0.35, 0.21-0.56) and for mild cognitive impairment from 2010-2012 (0.54, 0.36-0.79) to 2013-2015 (0.36, 0.24-0.53). CONCLUSIONS For children born very preterm between 2001 and 2015 in Taiwan, the improvement of maternal education levels and improvements in neonatal brain injury and mortality were temporally associated with trends of decreasing intellectual impairment at school age across all GA groups.

Abstract
Importance The Apgar score is used worldwide as an assessment tool to estimate the vitality of newborns in their first minutes of life. Its applicability to estimate neurodevelopmental outcomes in infants born extremely preterm (EPT; <28 weeks' gestation) is not well established. Objective To investigate the association between the Apgar score and neurodevelopmental outcomes in infants born EPT. Design, Setting, and Participants This cohort study was conducted using data from the Effective Perinatal Intensive Care in Europe-Screening to Improve Health in Very Preterm Infants in Europe (EPICE-SHIPS) study, a population-based cohort in 19 regions of 11 European countries in 2011 to 2012. Clinical assessments of cognition and motor function at age 5 years were performed in infants born EPT and analyzed in January to July 2023. Exposures Apgar score at 5 minutes of life categorized into 4 groups (0-3, 4-6, 7-8, and 9-10 points). Main Outcomes and Measures Cognitive and motor outcomes were assessed using the Wechsler Preschool and Primary Scale of Intelligence test of IQ derived from locally normed versions by country and the Movement Assessment Battery for Children-Second Edition. Parents additionally provided information on communication and problem-solving skills using the Ages and Stages Questionnaire, third edition (ASQ-3). All outcomes were measured as continuous variables. Results From the total cohort of 4395 infants born EPT, 2522 infants were live born, 1654 infants survived to age 5 years, and 996 infants (478 females [48.0%]) followed up had at least 1 of 3 outcome measures. After adjusting for sociodemographic variables, perinatal factors, and severe neonatal morbidities, there was no association of Apgar score with IQ, even for scores of 3 or less (β = -3.3; 95% CI, -10.5 to 3.8) compared with the score 9 to 10 category. Similarly, no association was found for ASQ-3 (β = -2.1; 95% CI, -24.6 to 20.4). Congruent results for Apgar scores of 3 or less were obtained for motor function scores for all children (β = -4.0; 95% CI, -20.1 to 12.1) and excluding children with a diagnosis of cerebral palsy (β = 0.8, 95% CI -11.7 to 13.3). Conclusions and Relevance This study found that low Apgar scores were not associated with longer-term outcomes in infants born EPT. This finding may be associated with high interobserver variability in Apgar scoring, reduced vitality signs and poorer responses to resuscitation after birth among infants born EPT, and the association of more deleterious exposures in the neonatal intensive care unit or of socioeconomic factors with greater changes in outcomes during the first 5 years of life.

Abstract
Gut dysbiosis is associated with sepsis and necrotizing enterocolitis in preterm infants, which can adversely affect long-term growth and neurodevelopment. We aimed to synthesise evidence for the effect of probiotic supplementation on growth and neurodevelopmental outcomes in preterm infants. MEDLINE, EMBASE, EMCARE, Cochrane CENTRAL, and grey literature were searched in February 2022. Only randomized controlled trials (RCTs) were included. Meta-analysis was performed using random effects model. Effect sizes were expressed as standardized mean difference (SMD), mean difference (MD) or risk ratio (RR) and their corresponding 95% confidence intervals (CI). Risk of Bias (ROB) was assessed using the ROB-2 tool. Certainty of Evidence (CoE) was summarized using GRADE guidelines. Thirty RCTs (n = 4817) were included. Meta-analysis showed that probiotic supplementation was associated with better short-term weight gain [SMD 0.24 (95%CI 0.04, 0.44); 22 RCTs (n = 3721); p = 0.02; I2 = 88%; CoE: low]. However, length [SMD 0.12 (95%CI -0.13, 0.36); 7 RCTs, (n = 899); p = 0.35; I2 = 69%; CoE: low] and head circumference [SMD 0.09 (95%CI -0.15, 0.34); 8 RCTs (n = 1132); p = 0.46; I2 = 76%; CoE: low] were similar between the probiotic and placebo groups. Probiotic supplementation had no effect on neurodevelopmental impairment [RR 0.91 (95%CI 0.76, 1.08); 5 RCTs (n = 1556); p = 0.27; I2 = 0%; CoE: low]. Probiotic supplementation was associated with better short-term weight gain, but did not affect length, head circumference, long-term growth, and neurodevelopmental outcomes of preterm infants. Adequately powered RCTs are needed in this area. Prospero Registration: CRD42020064992.

Arch Dis Child Fetal Neonatal Ed 2023; 108:458-463. [PMID: 36270779 DOI: 10.1136/archdischild-2022-324457] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Accepted: 10/01/2022] [Indexed: 11/03/2022]
Abstract
OBJECTIVE Survival rates of extremely premature infants are rising, but changes in neurodevelopmental impairment (NDI) rates are unclear. Our objective was to perform a systematic review of intrainstitutional variability of NDI over time. DESIGN Systematic review and meta-analysis. DATA SOURCES Ovid MEDLINE, Embase, PubMed, Cochrane Library and Google Scholar. STUDY SELECTION Study eligibility: (1) at least two discrete cohorts of infants born <27 weeks' gestation or <1000 g birth weight, (2) one cohort born after 1990 and at least one subsequent cohort of similar gestational age, (3) all cohorts cared for within the same Neonatal Intensive Care Unit(s) (NICU) and (4) neurodevelopmental outcomes at 18-36 months corrected age. MAIN OUTCOME Change in NDI rates. Quality, validity and bias were assessed using Grading of Recommendations, Assessment, Development, and Evaluation and Quality in Prognosis Studies guidelines. RESULTS Of 203 publications, 15 were eligible, including 13 229 infants. At the first time point, average NDI rate across study groups weighted by sample size was 41.0% (95% CI 34.0% to 48.0%). The average change in NDI between time points was -3.3% (95% CI -8·8% to 2.2%). For each added week of gestation at birth, the rate of NDI declined by 9.7% (95% CI 6.2% to 13.3%). Most studies exhibited moderate-severe bias in at least one domain, especially attrition rates. CONCLUSIONS When comparing discrete same-centre cohorts over time, there was no significant change in NDI rates in infants born <27 weeks' gestation or <1000 g. Higher survival rates unaccompanied by improvement in neurodevelopment highlight urgency for renewed focus on the causes of NDI and evidence-based strategies to reduce brain injury.

Abstract
AIM To assess the predictive validity of parent-reported gross motor impairment (GMI) at age 2 years to detect significant movement difficulties at age 5 years in children born extremely preterm. METHOD Data were from 556 children (270 males, 286 females) born at less than 28 weeks' gestation in 2011 to 2012 in 10 European countries. Parent report of moderate/severe GMI was defined as walking unsteadily or unable to walk unassisted at 2 years corrected age. Examiners assessed significant movement difficulties (score ≤ 5th centile on the Movement Assessment Battery for Children, Second Edition) and diagnoses of cerebral palsy (CP) were collected by parent report at 5 years chronological age. RESULTS At 2 years, 66 (11.9%) children had moderate/severe GMI. At 5 years, 212 (38.1%) had significant movement difficulties. Parent reports of GMI at age 2 years accurately classified CP at age 5 years in 91.0% to 93.2% of children. Classification of moderate/severe GMI at age 2 years had high specificity (96.2%; 95% confidence interval 93.6-98.0) and positive predictive value (80.3%; 68.7-89.1) for significant movement difficulties at age 5 years. However, 74.5% of children with significant movement difficulties at 5 years were not identified with moderate/severe GMI at age 2 years, resulting in low sensitivity (25.1%; 19.4-31.5). INTERPRETATION This questionnaire may be used to identify children born extremely preterm who at age 2 years have a diagnosis of CP or movement difficulties that are likely to have a significant impact on their functional outcomes at age 5 years.

BMC Pediatr 2023; 23:421. [PMID: 37620856 PMCID: PMC10463455 DOI: 10.1186/s12887-023-04254-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Accepted: 08/17/2023] [Indexed: 08/26/2023] Open
Abstract
BACKGROUND Survival following extreme preterm birth has improved, potentially increasing the number of children with ongoing morbidity requiring intensive care in childhood. Previous single-centre studies have suggested that long-stay admissions in paediatric intensive care units (PICUs) are increasing. We aimed to examine trends in long-stay admissions (≥28 days) to PICUs in England, outcomes for this group (including mortality and PICU readmission), and to determine the contribution of preterm-born children to the long-stay population, in children aged <2 years. METHODS Data was obtained from the Paediatric Intensive Care Audit Network (PICANet) for all children <2 years admitted to National Health Service PICUs from 1/1/2008 to 31/12/2018 in England. We performed descriptive analysis of child characteristics and PICU outcomes. RESULTS There were 99,057 admissions from 67,615 children. 2,693 children (4.0%) had 3,127 long-stays. Between 2008 and 2018 the annual number of long-stay admissions increased from 225 (2.7%) to 355 (4.0%), and the proportion of bed days in PICUs occupied by long-stay admissions increased from 24.2% to 33.2%. Of children with long-stays, 33.5% were born preterm, 53.5% were born at term, and 13.1% had missing data for gestational age. A considerable proportion of long-stay children required PICU readmission before two years of age (76.3% for preterm-born children). Observed mortality during any admission was also disproportionately greater for long-stay children (26.5% for term-born, 24.8% for preterm-born) than the overall rate (6.3%). CONCLUSIONS Long-stays accounted for an increasing proportion of PICU activity in England between 2008 and 2018. Children born preterm were over-represented in the long-stay population compared to the national preterm birth rate (8%). These results have significant implications for future research into paediatric morbidity, and for planning future PICU service provision.

Abstract
AIM Systemic postnatal corticosteroids are used to treat or prevent bronchopulmonary dysplasia (BPD) in extremely preterm (EP) or extremely low birth weight (ELBW) infants but are associated with long-term harm. We aimed to assess the relationship between cumulative postnatal corticosteroid dose and neurodevelopmental outcomes. METHODS Longitudinal cohort study of all EP/ELBW livebirths in Victoria, Australia 2016-2017. Perinatal data were collected prospectively. Neurodevelopmental assessment was performed at 2 years' corrected age. Linear and logistic regression were used to determine relationships between cumulative corticosteroid dose and neurodevelopment, adjusted for gestational age, birth weight, sex and major intraventricular haemorrhage. RESULTS Seventy-six EP/ELBW infants received postnatal corticosteroids to treat or prevent BPD, 62/65 survivors were seen at 2 years. Median (IQR) cumulative postnatal corticosteroid dose was 1.36 (0.92-3.45) mg/kg dexamethasone equivalent. Higher cumulative corticosteroid dose was associated with increased odds of cerebral palsy, adjusted OR (95% CI) 1.47 (1.04, 2.07). Higher cumulative corticosteroid dose was also associated with lower cognitive and motor developmental scores, however, this weakened after adjustment for confounding variables: cognitive composite score adjusted coefficient (95% CI) -1.3 (-2.7, 0.1) and motor composite score adjusted coefficient (95% CI) -1.3 (-2.8, 0.2). CONCLUSION Higher cumulative postnatal corticosteroid dose in EP/ELBW infants is associated with increased odds of cerebral palsy at 2 years' corrected age. Adequately powered studies are needed to assess the independent effects of cumulative steroid dose on neurodevelopmental outcomes.

Int J Mol Sci 2023; 24:ijms24097804. [PMID: 37175511 PMCID: PMC10178601 DOI: 10.3390/ijms24097804] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Revised: 04/13/2023] [Accepted: 04/22/2023] [Indexed: 05/15/2023] Open
Abstract
The risk of oxidative stress is unavoidable in preterm infants and increases the risk of neonatal morbidities. Premature infants often require sedation and analgesia, and the commonly used opioids and benzodiazepines are associated with adverse effects. Impairment of cerebellar functions during cognitive development could be a crucial factor in neurodevelopmental disorders of prematurity. Recent studies have focused on dexmedetomidine (DEX), which has been associated with potential neuroprotective properties and is used as an off-label application in neonatal units. Wistar rats (P6) were exposed to 80% hyperoxia for 24 h and received as pretreatment a single dose of DEX (5µg/kg, i.p.). Analyses in the immature rat cerebellum immediately after hyperoxia (P7) and after recovery to room air (P9, P11, and P14) included examinations for cell death and inflammatory and oxidative responses. Acute exposure to high oxygen concentrations caused a significant oxidative stress response, with a return to normal levels by P14. A marked reduction of hyperoxia-mediated damage was demonstrated after DEX pretreatment. DEX produced a much earlier recovery than in controls, confirming a neuroprotective effect of DEX on alterations elicited by oxygen stress on the developing cerebellum.

Abstract
Impaired cerebellar development of premature infants and the associated impairment of cerebellar functions in cognitive development could be crucial factors for neurodevelopmental disorders. Anesthetic- and hyperoxia-induced neurotoxicity of the immature brain can lead to learning and behavioral disorders. Dexmedetomidine (DEX), which is associated with neuroprotective properties, is increasingly being studied for off-label use in the NICU. For this purpose, six-day-old Wistar rats (P6) were exposed to hyperoxia (80% O2) or normoxia (21% O2) for 24 h after DEX (5 µg/kg, i.p.) or vehicle (0.9% NaCl) application. An initial detection in the immature rat cerebellum was performed after the termination of hyperoxia at P7 and then after recovery in room air at P9, P11, and P14. Hyperoxia reduced the proportion of Calb1+-Purkinje cells and affected the dendrite length at P7 and/or P9/P11. Proliferating Pax6+-granule progenitors remained reduced after hyperoxia and until P14. The expression of neurotrophins and neuronal transcription factors/markers of proliferation, migration, and survival were also reduced by oxidative stress in different manners. DEX demonstrated protective effects on hyperoxia-injured Purkinje cells, and DEX without hyperoxia modulated neuronal transcription in the short term without any effects at the cellular level. DEX protects hyperoxia-damaged Purkinje cells and appears to differentially affect cerebellar granular cell neurogenesis following oxidative stress.

Abstract
BACKGROUND Extremely preterm (EPT) infants (≤28 weeks) remain at risk for poor outcomes. Small baby protocols (SBPs) may improve outcomes, but optimal strategies are unknown. METHODS This study evaluated whether EPT infants managed using an SBP would have better outcomes compared to a historical control (HC) group. The study compared a HC group of EPT infants 23 0/7 weeks to 28 0/7 weeks GA (2006-2007), to a similar SBP group (2007-2008). Survivors were followed until 13 years of life. The SBP emphasized antenatal steroids, delayed cord clamping, respiratory and hemodynamic minimalism, prophylactic indomethacin, early empiric caffeine, and control of sound and light. RESULTS There were 35 HC subjects and 35 SBP subjects. The SBP group had less severe IVH-PVH (9 % vs. 40 %, risk ratio 0.7, 95 % CI 0.5-0.9, P = 0.002) mortality (17 % vs. 46 %, risk ratio 0.6, 95 % CI 0.5-0.9, P = 0.004), and acute pulmonary hemorrhage (6 % vs. 23 %, risk ratio 0.8, 95 % CI 0.7-1.0, P = 0.04). Compliance with the SBP protocol was excellent. For the SBP group in the first 72 h, no subjects received inotropes, hydrocortisone, or sodium bicarbonate. Intubation, mechanical ventilation, fluid boluses, sedation, red blood cell transfusions, and insulin use decreased. At 10-13 years, more SBP subjects had survived without NDI (51 % vs. 23 %, risk ratio = 1.6, 95 % CI = 1.1-2.4, P = 0.01). More SBP subjects also survived without NDI and with a Vineland Adaptive Behavior Composite score > 85 (44 % vs. 11 %, risk ratio = 2.0, 95 % CI = 1.2-3.2, P ≤0.001). The SBP group had less visual impairment. CONCLUSION An SBP was associated with improved outcomes, including normal neurologic survival after 10 years.

Abstract
Background Infants born extremely preterm (<28 weeks' gestation) are at high risk of neurodevelopmental impairment (NDI) with 50% of survivors showing moderate or severe NDI when at 2 years of age. We sought to develop novel models by which to predict neurodevelopmental outcomes, hypothesizing that combining baseline characteristics at birth with medical care and environmental exposures would produce the most accurate model. Methods Using a prospective database of 692 infants from the Preterm Epo Neuroprotection (PENUT) Trial, which was carried out between December 2013 and September 2016, we developed three predictive algorithms of increasing complexity using a Bayesian Additive Regression Trees (BART) machine learning approach to predict both NDI and continuous Bayley Scales of Infant and Toddler Development 3rd ed subscales at 2 year follow-up using: 1) the 5 variables used in the National Institute of Child Health and Human Development (NICHD) Extremely Preterm Birth Outcomes Tool, 2) 21 variables associated with outcomes in extremely preterm (EP) infants, and 3) a hypothesis-free approach using 133 potential variables available for infants in the PENUT database. Findings The NICHD 5-variable model predicted 3-4% of the variance in the Bayley subscale scores, and predicted NDI with an area under the receiver operator curve (AUROC, 95% CI) of 0.62 (0.56-0.69). Accuracy increased to 12-20% of variance explained and an AUROC of 0.77 (0.72-0.83) when using the 21 pre-selected clinical variables. Hypothesis-free variable selection using BART resulted in models that explained 20-31% of Bayley subscale scores and AUROC of 0.87 (0.83-0.91) for severe NDI, with good calibration across the range of outcome predictions. However, even with the most accurate models, the average prediction error for the Bayley subscale predictions was around 14-15 points, leading to wide prediction intervals. Higher total transfusion volume was the most important predictor of severe NDI and lower Bayley scores across all subscales. Interpretation While the machine learning BART approach meaningfully improved predictive accuracy above a widely used prediction tool (NICHD) as well as a model utilizing NDI-associated clinical characteristics, the average error remained approximately 1 standard deviation on either side of the true value. Although dichotomous NDI prediction using BART was more accurate than has been previously reported, and certain clinical variables such as transfusion exposure were meaningfully predictive of outcomes, our results emphasize the fact that the field is still not able to accurately predict the results of complex long-term assessments such as Bayley subscales in infants born EP even when using rich datasets and advanced analytic methods. This highlights the ongoing need for long-term follow-up of all EP infants. Funding Supported by the National Institute of Neurological Disorders and StrokeU01NS077953 and U01NS077955.

Protective Effects of Early Caffeine Administration in Hyperoxia-Induced Neurotoxicity in the Juvenile Rat. Antioxidants (Basel) 2023; 12:antiox12020295. [PMID: 36829854 PMCID: PMC9952771 DOI: 10.3390/antiox12020295] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Revised: 01/12/2023] [Accepted: 01/24/2023] [Indexed: 01/31/2023] Open
Abstract
High-risk preterm infants are affected by a higher incidence of cognitive developmental deficits due to the unavoidable risk factor of oxygen toxicity. Caffeine is known to have a protective effect in preventing bronchopulmonary dysplasia associated with improved neurologic outcomes, although very early initiation of therapy is controversial. In this study, we used newborn rats in an oxygen injury model to test the hypothesis that near-birth caffeine administration modulates neuronal maturation and differentiation in the hippocampus of the developing brain. For this purpose, newborn Wistar rats were exposed to 21% or 80% oxygen on the day of birth for 3 or 5 days and treated with vehicle or caffeine (10 mg/kg/48 h). Postnatal exposure to 80% oxygen resulted in a drastic reduction of associated neuronal mediators for radial glia, mitotic/postmitotic neurons, and impaired cell-cycle regulation, predominantly persistent even after recovery to room air until postnatal day 15. Systemic caffeine administration significantly counteracted the effects of oxygen insult on neuronal maturation in the hippocampus. Interestingly, under normoxia, caffeine inhibited the transcription of neuronal mediators of maturing and mature neurons. The early administration of caffeine modulated hyperoxia-induced decreased neurogenesis in the hippocampus and showed neuroprotective properties in the neonatal rat oxygen toxicity model.

Risk factors for cerebral palsy and movement difficulties in 5-year-old children born extremely preterm. Pediatr Res 2023:10.1038/s41390-022-02437-6. [PMID: 36694025 DOI: 10.1038/s41390-022-02437-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Revised: 11/10/2022] [Accepted: 11/19/2022] [Indexed: 01/26/2023]
Abstract
BACKGROUND Motor impairment is common after extremely preterm (EPT, <28 weeks' gestational age (GA)) birth, with cerebral palsy (CP) affecting about 10% of children and non-CP movement difficulties (MD) up to 50%. This study investigated the sociodemographic, perinatal and neonatal risk factors for CP and non-CP MD. METHODS Data come from a European population-based cohort of children born EPT in 2011-2012 in 11 countries. We used multinomial logistic regression to assess risk factors for CP and non-CP MD (Movement Assessment Battery for Children - 2nd edition ≤5th percentile) compared to no MD (>15th percentile) among 5-year-old children. RESULTS Compared to children without MD (n = 366), young maternal age, male sex and bronchopulmonary dysplasia were similarly associated with CP (n = 100) and non-CP MD (n = 224) with relative risk ratios (RRR) ranging from 2.3 to 3.6. CP was strongly related to severe brain lesions (RRR >10), other neonatal morbidities, congenital anomalies and low Apgar score (RRR: 2.4-3.3), while non-CP MD was associated with primiparity, maternal education, small for GA (RRR: 1.6-2.6) and severe brain lesions, but at a much lower order of magnitude. CONCLUSION CP and non-CP MD have different risk factor profiles, with fewer clinical but more sociodemographic risk factors for non-CP MD. IMPACT Young maternal age, male sex and bronchopulmonary dysplasia similarly increased risks of both cerebral palsy and non-cerebral palsy movement difficulties. Cerebral palsy was strongly related to clinical risk factors including severe brain lesions and other neonatal morbidities, while non-cerebral palsy movement difficulties were more associated with sociodemographic risk factors. These results on the similarities and differences in risk profiles of children with cerebral palsy and non-cerebral palsy movement difficulties raise questions for etiological research and provide a basis for improving the identification of children who may benefit from follow-up and early intervention.

Abstract
OBJECTIVE To evaluate the impact of necrotizing enterocolitis (NEC) on mortality in very low birth weight (VLBW) infants with intraventricular hemorrhage (IVH). STUDY DESIGN Data were collected on VLBW infants born 2014-2018 at Vermont Oxford Network (VON) centers. NEC and IVH were categorized by severity. Adjusted risk ratios (ARR) for in-hospital mortality were calculated. RESULTS This study included 187 187 VLBW infants. Both medical and surgical NEC increased mortality risk compared to those without NEC. Stratification by IVH severity modified this effect (no IVH: ARR 3.04 (95%CI 2.74-3.38) for medical NEC and 4.17 (3.84-4.52) for surgical NEC; mild IVH: ARR 2.14 (1.88-2.44) for medical NEC and 2.49 (2.24-2.78) for surgical NEC; severe IVH: ARR 1.14 (1.03-1.26) for medical NEC and 1.10 (1.02-1.18) for surgical NEC). CONCLUSION The relative impact of NEC on mortality decreased as IVH severity increased. Given the frequent coexistence of NEC and IVH, these data inform multidisciplinary management of these complex patients.

Abstract
Glucose impairment is common in preterm infants but the impact of early neonatal hyperglycemia on long term neurodevelopment is still highly controversial. This review reports current evidence of the effect of hyperglycemia on neurodevelopmental outcome. It was conducted according to the PRISMA guidelines. We searched MEDLINE via PubMed; EMBASE via Ovid; the Cochrane Central Register of Controlled Trials; the Cochrane Library; ClinicalTrials.gov; and the World Health Organization's International Trials Registry and Platform. We included studies that investigated the association between hyperglycemia, defined as at least one episode of glycemia ≥8 mmol/L, and neurodevelopment outcome evaluated either through the Griffiths Mental Developmental Scales (GMDS) or the Bayley Scales of Infant Development (BSID) for the first 5 years of life, and the Wechsler Intelligence Scale for Children (WISC) and the Movement Assessment Battery for Children (MABC) for the following age category. We selected six studies, comprising 2226 infants in total and which included 1059 (48%) infants for whom neurodevelopment assessment was available. We found an association between hyperglycemia and neurological delay in the first two years of life, especially for motor functions; this result was confirmed in later childhood. The quality of evidence was poor; therefore, the negative influence of neonatal hyperglycemia on the neurological development of preterm infants must be investigated in further studies.

Abstract
UNLABELLED The authors of this study evaluated infant and parent outcomes at 12 and 24 months after a clinician-supported, web-based early intervention for preterm infants. OBJECTIVE To examine the efficacy of a clinician-supported, web-based intervention delivered over the first year after birth compared with standard care in children born after <34 weeks' gestation, on child development at 24 months corrected age (CA), parental mental health, and the parent-child relationship at 24 months. METHODS We randomly allocated 103 preterm infants to clinician-supported, web-based intervention (n = 50) or standard care control (n = 53) groups. At 24 months CA, child cognitive, language, motor, social-emotional development, and the parent-child relationship were assessed. Parental mental health and quality of life were assessed at 12 and 24 months CA. RESULTS At 24 months, child development, maternal mental health, and maternal quality of life were similar for the intervention and control groups. There was some evidence that mothers in the intervention group had lower odds of being in the elevated category for depression at 12 months (odds ratio: 0.19; 95% confidence interval [CI]: 0.04-0.90; P = .04). Scores were higher in the intervention group for child responsiveness (mean difference: 0.57; 95% CI: 0.03-1.11; P = .04), child involvement (mean difference: 0.61; 95% CI: 0.09-1.13; P = .02), and maternal structuring (mean difference: 0.72; 95% CI: 0.22-1.21; P = .01) during the parent-infant interaction at 24 months. CONCLUSIONS This study provides preliminary evidence that a clinician-supported, web-based early intervention program for preterm infants had a positive effect on the parent-child relationship and maternal mental health immediately after the intervention but potentially little effect on child development.

Abstract
BACKGROUND Infants born extremely preterm (EP, <28-week gestational age) or extremely low birthweight (ELBW, <1000 g) are at risk of developmental delay and cerebral palsy (CP). The General Movements Assessment (GMA) and its extension, the Motor Optimality Score, revised (MOS-R) (assesses movement patterns and posture), may help to identify early delays. OBJECTIVES To compare differences in the MOS-R scored from parent-recorded videos between infants born EP/ELBW and term-born infants, to determine relationships between the MOS-R and 2-year cognitive, language and motor outcomes and if any relationships differ between birth groups and the association of the GMA (fidgety) with CP. METHODS A geographical cohort (EP/ELBW and term-control infants) was assessed using the MOS-R inclusive of the GMA at 3- to 4-month corrected age (CA), and the Bayley Scales of Infant and Toddler Development, 3rd edition (Bayley-III) at 2-year CA. Differences in mean total MOS-R between groups, relationships between MOS-R and 2-year outcomes and relationships between GMA (fidgety) and CP in infants born EP/ELBW were estimated using linear/logistic regression. RESULTS Three hundred and twelve infants (147 EP/ELBW; 165 term) had complete MOS-R and Bayley-III assessments. Mean MOS-R was lower in infants born EP/ELBW than controls (mean difference -3.2, 95% confidence interval [CI] -4.2, -2.3). MOS-R was positively related to cognitive (β [regression coefficient] = 0.71, 95% CI 0.27, 1.15), language (β = 0.96, 95% CI 0.38, 1.54) and motor outcomes (β = .89, 95% CI 0.45, 1.34). There was little evidence for interaction effects between birth groups for any outcome. Absent/abnormal fidgety movements were related to CP in children born EP/ELBW (risk ratio 5.91, 95% CI 1.48, 23.7). CONCLUSIONS Infants born EP/ELBW have lower MOS-R than infants born at term. A higher MOS-R is related to better outcomes for 2-year development, with similar relationships in both birth groups. Absent/abnormal fidgety movements are related to CP in EP/ELBW survivors.

Abstract
AIM To investigate temporal trends in birth prevalence, disability severity, and motor type for singletons with prenatal or perinatally acquired cerebral palsy (CP). METHOD Numerator data, number of children with CP born a singleton between 1995 and 2014, confirmed at 5 years of age, were drawn from three state registers with population-level ascertainment. Birth prevalence estimates and 95% confidence intervals (CI) were calculated per 1000 singleton live births for the three states combined, overall, by gestational age group, by dichotomized disability severity, and spastic laterality. Poisson regression models were used to analyse trends. Using data from all eight registers, trends in the proportional distribution of CP subtypes overall and stratified by gestational age were examined. RESULTS Birth prevalence of CP declined from 1.8 (95% CI 1.6-2.0) in 1995 to 1996 to 1.2 (95% CI 1.1-1.4) in 2013 to 2014 (average 5% per 2-year epoch, p < 0.001). Declines in birth prevalence were observed across all gestational age groups with the largest decline in children born at <28 weeks (average 8% per epoch, p < 0.001). Prevalence of moderate-severe disability declined for children born at <28 and ≥37 weeks (average 11% and 7% per epoch respectively, p < 0.001). The proportions of bilateral spastic CP declined (p < 0.001) at <28 weeks (p = 0.014) and ≥37 weeks (p < 0.001). The proportion of children with dyskinesia increased (28-31 weeks: p = 0.021, 32-36 weeks: p = 0.001, and ≥37 weeks: p < 0.001). INTERPRETATION Birth prevalence of CP and moderate-severe disability (<28 and ≥37 weeks) declined in Australian singletons between 1995 and 2014, reflecting changes in prenatal and perinatal care over time. WHAT THIS PAPER ADDS Declines in birth prevalence of prenatal or perinatally acquired cerebral palsy were observed for singletons born in Australia between 1995 and 2014. These declines were evident across all gestational age groups. Declines in birth prevalence of moderate-severe disability were observed for children born at <28 weeks and ≥37 weeks.

Trends in survival, perinatal morbidities and two-year neurodevelopmental outcomes in extremely low-birthweight infants over four decades. Paediatr Perinat Epidemiol 2022; 36:594-602. [PMID: 35437828 DOI: 10.1111/ppe.12879] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/08/2021] [Revised: 02/25/2022] [Accepted: 03/19/2022] [Indexed: 11/30/2022]
Abstract
BACKGROUND Although outcomes for infants born extremely low birthweight (ELBW; <1000 g birthweight) have improved over time, it is important to document survival and morbidity changes following the advent of modern neonatal intensive care in the 1990s. OBJECTIVE To describe trends in survival, perinatal outcomes and neurodevelopment to 2 years' corrected age over time across six discrete geographic cohorts born ELBW between 1979 and 2017. METHODS Analysis of data from discrete population-based prospective cohort studies of all live births free of lethal anomalies with birthweight 500-999 g in the state of Victoria, Australia, over 6 eras: 1979-80, 1985-87, 1991-92, 1997, 2005 and 2016-17. Perinatal data collected included survival, duration and type of respiratory support, neonatal morbidities and two-year neurodevelopmental outcomes. RESULTS More ELBW live births were inborn (born in a maternity hospital with a neonatal intensive care unit) over time (1979-80, 70%; 2016-17, 84%), and more were offered active care (1979-80, 58%; 2016-17, 90%). Survival to 2 years rose substantially, from 25% in 1979-80 to 80% in 2016-17. In survivors, rates of any assisted ventilation rose from 75% in 1979-80 to 99% in 2016-17. Cystic periventricular leukomalacia, severe retinopathy of prematurity and blindness improved across eras. Two-year data were available for 95% (1054/1109) of survivors. Rates of cerebral palsy, deafness and major neurodevelopmental disability changed little over time. The annual numbers with major neurodevelopmental disability increased from 12.5 in 1979-80 to 30 in 2016-17, but annual numbers free of major disability increased much more, from 31 in 1979-80 to 147 in 2016-17. CONCLUSIONS Active care and survival rates in ELBW children have increased dramatically since 1979 without large changes in neonatal morbidities. The numbers of survivors free of major neurodevelopmental disability have increased more over time than those with major disability.

Gunn-Charlton JK. Impact of Comorbid Prematurity and Congenital Anomalies: A Review. Front Physiol 2022; 13:880891. [PMID: 35846015 PMCID: PMC9284532 DOI: 10.3389/fphys.2022.880891] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Accepted: 04/11/2022] [Indexed: 11/13/2022] Open
Abstract
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.

Dev Med Child Neurol 2022; 64:855-862. [PMID: 35103304 DOI: 10.1111/dmcn.15167] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2021] [Revised: 12/20/2021] [Accepted: 12/22/2021] [Indexed: 12/17/2022]
Abstract
AIM To determine the relationship between early motor repertoire and 2-year neurodevelopment in infants born extremely preterm (<28 weeks' gestation) or extremely-low-birthweight (ELBW) (<1000g). METHOD This was a geographical prospective cohort of 139 infants born extremely preterm/ELBW (mean gestational age 26.7 weeks, standard deviation [SD] 2.0, 68/139 [49%] male), with parent-recorded videos suitable for scoring the General Movements Assessment (GMA). Motor repertoire was assessed using the Motor Optimality Score-Revised (MOS-R), with and without the fidgety movement subsection, and the GMA alone at 12 to 13+6 weeks corrected age and 14 to 15+6 weeks corrected age. At 2 years corrected age, impaired development was defined as Bayley Scales of Infant and Toddler Development, Third Edition motor and cognitive development scores 1SD or less relative to controls born at term; paediatricians diagnosed cerebral palsy (CP). RESULTS Greater MOS-R scores at 14 to 15+6 weeks corrected age were associated with lower odds of CP (odds ratio [OR] per 1-point increase=0.83, 95% confidence interval [CI]=0.71-0.99), and motor (OR=0.93, 95% CI=0.87-0.99), or cognitive impairment (OR=0.94, 95% CI=0.88-0.99). Absent/abnormal GMA at 14 to 15+6 weeks was associated with CP and motor delay. There was little evidence that MOS-R scores at 12 to 13+6 weeks were associated with neurodevelopmental outcomes at 2 years. INTERPRETATION Poorer MOS-R scores and absent/abnormal GMA, scored from parent-recorded videos at 14 to 15+6 weeks gestational age, are associated with CP and developmental impairment in 2-year-old infants born extremely preterm/ELBW.

Abstract
BACKGROUND AND OBJECTIVES Children born extremely preterm (EPT), <28 weeks' gestational age, face higher risks of movement difficulties than their term-born peers. Studies report varying prevalence estimates and prognostic factors identifying children who could benefit from early intervention are inconsistent. This study investigated the prevalence of movement difficulties in children born EPT and associated risk factors. METHODS Data come from a population-based EPT birth cohort in 2011 and 2012 in 11 European countries. Children without cerebral palsy were assessed at 5 years of age (N = 772) with the Movement Assessment Battery for Children-Second Edition, which classifies movement difficulties as none (>15th percentile), at risk (6th-15th percentile) and significant (≤5th percentile). Associations with sociodemographic, perinatal, and neonatal characteristics collected from obstetric and neonatal medical records and parental questionnaires were estimated using multinomial logistic regression. RESULTS We found 23.2% (n = 179) of children were at risk for movement difficulties and 31.7% (n = 244) had significant movement difficulties. Lower gestational age, severe brain lesions, and receipt of postnatal corticosteroids were associated with significant movement difficulties, whereas male sex and bronchopulmonary dysplasia were associated with being at risk and having significant movement difficulties. Children with younger, primiparous, less educated, and non-European-born mothers were more likely to have significant movement difficulties. Differences in prevalence between countries remained after population case-mix adjustments. CONCLUSIONS This study confirms a high prevalence of movement difficulties among EPT children without cerebral palsy, which are associated with perinatal and neonatal risk factors as well as sociodemographic characteristics and country.

The Conflicting Role of Caffeine Supplementation on Hyperoxia-Induced Injury on the Cerebellar Granular Cell Neurogenesis of Newborn Rats. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2022; 2022:5769784. [PMID: 35693697 PMCID: PMC9175096 DOI: 10.1155/2022/5769784] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/17/2022] [Revised: 03/04/2022] [Accepted: 04/28/2022] [Indexed: 11/28/2022]
Abstract
Preterm birth disrupts cerebellar development, which may be mediated by systemic oxidative stress that damages neuronal developmental stages. Impaired cerebellar neurogenesis affects several downstream targets important for cognition, emotion, and speech. In this study, we demonstrate that oxidative stress induced with high oxygen (80%) for three or five postnatal days (P3/P5) could significantly damage neurogenesis and proliferative capacity of granular cell precursor and Purkinje cells in rat pups. Reversal of cellular neuronal damage after recovery to room air (P15) was augmented by treatment with caffeine. However, downstream transcripts important for migration and differentiation of postmitotic granular cells were irreversibly reduced by hyperoxia, without rescue by caffeine. Protective effects of caffeine in the cerebellum were limited to neuronal survival but failed to restore important transcript signatures.

Abstract
OBJECTIVE To compare mortality and rates of significant neurosensory impairment (sNSI) at 18-36 months' corrected age in infants born extremely preterm across three international cohorts. DESIGN Retrospective analysis of prospectively collected neonatal and follow-up data. SETTING Three population-based observational cohort studies: the Australian and New Zealand Neonatal Network (ANZNN), the Canadian Neonatal and Follow-up Networks (CNN/CNFUN) and the French cohort Etude (Epidémiologique sur les Petits Ages Gestationnels: EPIPAGE-2). PATIENTS Extremely preterm neonates of <28 weeks' gestation in year 2011. MAIN OUTCOME MEASURES Primary outcome was composite of mortality or sNSI defined by cerebral palsy with no independent walking, disabling hearing loss and bilateral blindness. RESULTS Overall, 3055 infants (ANZNN n=960, CNN/CNFUN n=1019, EPIPAGE-2 n=1076) were included in the study. Primary composite outcome rates were 21.3%, 20.6% and 28.4%; mortality rates were 18.7%, 17.4% and 26.3%; and rates of sNSI among survivors were 4.3%, 5.3% and 3.3% for ANZNN, CNN/CNFUN and EPIPAGE-2, respectively. Adjusted for gestational age and multiple births, EPIPAGE-2 had higher odds of composite outcome compared with ANZNN (OR 1.71, 95% CI 1.38 to 2.13) and CNN/CNFUN (OR 1.72, 95% CI 1.39 to 2.12). EPIPAGE-2 did have a trend of lower odds of sNDI but far short of compensating for the significant increase in mortality odds. These differences may be related to variations in perinatal approach and practices (and not to differences in infants' baseline characteristics). CONCLUSIONS Composite outcome of mortality or sNSI for extremely preterm infants differed across high-income countries with similar baseline characteristics and access to healthcare.

Abstract
OBJECTIVES The aim of the study was to assess cognitive outcomes in children with intestinal failure (IF) and children at high risk of IF with conditions affecting the small intestine requiring parenteral nutrition. METHODS EMBASE, Cochrane, Web of Science, Google Scholar, MEDLINE, and PsycINFO were searched from inception to October 2020. Studies were included constituting original data on developmental quotient (DQ), intelligence quotient (IQ) and/or severe developmental delay/disability (SDD) rates assessed with standardized tests. We used appropriate standardized tools to extract data and assess study quality. We performed random effects meta-analyses to estimate pooled means of DQ/IQ and pooled SDD rates (general population mean for DQ/IQ: 100, for percentage with SDD: 1.8%) for 4 groups: IF, surgical necrotizing enterocolitis (NEC), abdominal wall defects (AWD), and midgut malformations (MM). Associations of patient characteristics with DQ/IQ were evaluated with meta-regressions. RESULTS Thirty studies met the inclusion criteria. The pooled mean DQ/IQ for IF, NEC, AWD, and MM were 86.8, 83.3, 96.6, and 99.5, respectively. The pooled SDD rates for IF, NEC, AWD and MM were 28.6%, 32.8%, 8.5%, and 3.7%, respectively. Meta-regressions indicated that lower gestational age, longer hospital stay, and higher number of surgeries but not parenteral nutrition duration, were associated with lower DQ/IQ. CONCLUSIONS Adverse developmental outcomes are common in children with IF and NEC, and to a much lesser extent in children with AWD and MM. It is important to monitor cognitive development in children with conditions affecting the small intestine and to explore avenues for prevention and remediation.

Abstract
Decision-making at the border of viability remains challenging for the expectant parents and the medical team. The preterm infant is dependent on others making the decision that will impact them for a lifetime in hopefully their best interest. Besides survival and survival without neurodevelopmental impairment, other relevant outcome measures, such as the quality of life of former preterm infants and the impact on family life, need to be integrated into prenatal counselling. Recommendations and national guidelines continue to rely on arbitrarily set gestational age limits at which treatment is not recommended, can be considered and it is recommended. These guidelines neglect other individual prognostic outcome factors like antenatal steroids, birth weight and gender. Besides individual factors, centre-specific factors like perinatal treatment intensity and the attitude of healthcare professionals significantly determine the futures of these infants at the border of viability. A more comprehensive approach regarding treatment recommendations and relevant outcome measures is necessary.

Abstract
BACKGROUND Survival rate increases for preterm infants, but long-term neurodevelopmental outcome predictors are lacking. Our primary aim was to determine whether a specific proteomic profile in cerebrospinal fluid (CSF) of preterm infants differs from that of term infants and to identify novel biomarkers of neurodevelopmental outcome in preterm infants. METHODS Twenty-seven preterm infants with median gestational age 27 w + 4 d and ten full-term infants were enrolled prospectively. Protein profiling of CSF were performed utilizing an antibody suspension bead array. The relative levels of 178 unique brain derived proteins and inflammatory mediators, selected from the Human Protein Atlas, were measured. RESULTS The CSF protein profile of preterm infants differed from that of term infants. Increased levels of brain specific proteins that are associated with neurodevelopment and neuroinflammatory pathways made up a distinct protein profile in the preterm infants. The most significant differences were seen in proteins involved in neurodevelopmental regulation and synaptic plasticity, as well as components of the innate immune system. Several proteins correlated with favorable outcome in preterm infants at 18-24 months corrected age. Among the proteins that provided strong predictors of outcome were vascular endothelial growth factor C, Neurocan core protein and seizure protein 6, all highly important in normal brain development. CONCLUSION Our data suggest a vulnerability of the preterm brain to postnatal events and that alterations in protein levels may contribute to unfavorable neurodevelopmental outcome.
