Abstract
The authors demonstrate the increment of clinical validity in early childhood assessment of physical impairment (PI), developmental delay (DD), and autism (AUT) using multiple standardized developmental screening measures such as performance measures and parent and teacher rating scales. Hierarchical regression and sensitivity/specificity analyses were used to identify the differential impact of each domain the scales measure. Significant findings include (a) self-help domains in either parent or teacher questionnaires are more significant contributors than social-emotional domains to early detection, (b) performance measures are stronger predictors than parent or teacher questionnaires in detecting physical impairment or developmental delay, and (c) parent questionnaires measuring self-help skills are a stronger predictor of autism than performance measures. These results support the combined use of parent and teacher rating scales and provide important implications in choosing instruments for different developmental disorders when time and resources are limited.

Abstract
INTRODUCTION Preterm children are at greater risk of developmental impairment and require close follow-up for early and optimal medical care. Our goal was to examine use of the parent-completed Ages and Stages Questionnaire (ASQ) as a screening tool for neurodevelopmental disabilities in preterm infants at five years of age. PATIENTS AND METHODS A total of 648 preterm children (<35 weeks gestational age) born between 2003 and 2004 and included in the regional Loire Infant Follow-up network were evaluated at five years of age. ASQ was compared with two validated tools (Intelligence Quotient and Global School Adaptation Score) and the impact of maternal education on the accuracy of this questionnaire was assessed. RESULTS Overall ASQ scores for predicting full-scale IQ<85 and GSA score produced an area under the receiver operating characteristic curve of 0.73±0.03 and 0.77±0.03, respectively. An ASQ cut-off value of 285 had optimal discriminatory power for identifying children with IQ scores<85 and GSA scores in the first quintile. ASQ values<285 were significantly associated with a higher risk of non-optimal neurologic outcomes (sensitivity of 0.80, specificity of 0.54 for IQ<85). ASQ values>285 were not distinctive for mild delay or normal development. In children with developmental delay, no difference was found when ASQ scores according to maternal education levels were analyzed. CONCLUSIONS ASQ at five years is a simple and cost-effective tool that can detect severe developmental delay in preterm children regardless of maternal education level, while its capacity to identify children with mild delay appears to be more limited.

Abstract
OBJECTIVE The authors performed a randomised trial in very preterm small-for-gestational age (SGA) babies to determine if prophylaxis with granulocyte-macrophage colony-stimulating factor (GM-CSF) improves outcomes (the PROGRAMS trial). Despite increased neutrophil counts following GM-CSF, the authors reported no significant difference in neonatal sepsis-free survival. PATIENTS AND METHODS 280 babies born <31 weeks of gestation and SGA were entered into the trial. Outcome was determined at 2 years to determine neurodevelopmental and general health outcomes, including economic costs. RESULTS The authors found no significant differences in health outcomes or health and social care costs between the trial groups. In the GM-CSF arm, 87 of 134 (65%) babies survived to 2 years without severe disability compared with 87 of 131 (66%) controls (RR: 1·0, 95% CI 0·8 to 1·2). Marginally, more children receiving GM-CSF were reported to have cough (RR 1·7, 95% CI 1·1 to 2·6) and had signs of chronic respiratory disease (Harrison's sulcus; RR 2·0, 95% CI 1·0 to 3·9) though this was not reflected in bronchodilator use or need for hospitalisation for respiratory disease. Overall, the rate of neurologic abnormality (7%-9%) was similar but mean overall developmental scores were lower than expected for gestational age. CONCLUSIONS The administration of GM-CSF to very preterm SGA babies is not associated with improved or more adverse outcomes at 2 years of age. The apparent excess of developmental impairment in the entire PROGRAMS cohort, without corresponding increase in neurological abnormality, may represent diffuse brain injury attributable to intrauterine growth restriction.

Abstract
We investigated whether and to what extent children who are racial/ethnic minorities are disproportionately represented in early intervention and/or early childhood special education (EC/ECSE). We did so by analyzing a large sample of 48-month-olds (N=7,950) participating in the Early Childhood Longitudinal Study-Birth Cohort (ECLS-B), a nationally representative dataset of children born in the U.S. in 2001. Multivariate logistic regression analyses indicate that boys (OR=1.66), children born at very low birthweight (OR=3.98) or with congenital anomalies (OR=2.17), and children engaging in externalizing problem behaviors (OR=1.10) are more likely to be represented in EI/ECSE. Children from low SES households (OR=.48), those displaying greater numeracy or receptive language knowledge (ORs=.96 and .76, respectively), and children being raised in households where a language other than English is primarily spoken (OR=.39) are less likely to be represented in EI/ECSE. Statistical control for these and an extensive set of additional factors related to cognitive and behavioral functioning indicated that 48-month-old children who are Black (OR=.24) or Asian (OR=.32) are disproportionately under-represented in EI/ECSE in the U.S.

Abstract
PURPOSE The authors examined speech intelligibility in typically developing (TD) children and 3 groups of children with cerebral palsy (CP) who were classified into speech/language profile groups following Hustad, Gorton, and Lee (2010). Questions addressed differences in transcription intelligibility scores among groups, the effects of utterance length on intelligibility, the relationship between ordinal ratings of intelligibility and orthographic transcription intelligibility scores, and the difference between parent and naïve listener ordinal ratings. METHOD Speech samples varying in length from 1 to 7 words were elicited from 23 children with CP ( M (age) = 54.3 months) and 20 TD children ( M (age) = 55.1 months). Two hundred fifteen naïve listeners made orthographic transcriptions and ordinal ratings of intelligibility. Parent ordinal ratings of intelligibility were obtained from a previous study (Hustad et al., 2010). RESULTS Intelligibility varied with speech/language profile group and utterance length, with different patterns observed by profile group. Ratings of intelligibility by parents and naïve listeners did not differ, and both were highly correlated with transcription intelligibility scores. CONCLUSION Intelligibility was reduced for all groups of children with CP relative to TD children, suggesting the importance of speech-language intervention and the need for research investigating variables associated with changes in intelligibility in children.

Abstract
BACKGROUND Serial assessments of cognitive and language development are recommended for very preterm children, but standardized neuropsychological testing is time-consuming and expensive, as well as tiring for the child. AIMS To validate the Italian version of the PARCA-R parent questionnaire and test its clinical effectiveness in assessing cognitive development of very preterm children at 2 years of corrected age. METHODS 120 consecutive Italian very preterm children (mean gestational age 28.8 weeks, standard deviation 2.1) were assessed in four hospitals through the Mental Development Index (MDI) of the Bayley Scales of Infant Development (BSID-II). Parents completed the PARCA-R questionnaire, designed to measure children's non-verbal and verbal (vocabulary and sentence complexity) cognitive level. The correlation between the MDI and the PARCA-R Parent Report Composite (PRC) was tested through the Pearson correlation coefficient, and the receiver operating characteristic (ROC) curve was used to identify optimal PRC cut-offs. RESULTS Significant correlation between the PRC score and MDI (r=0.60, p<0.001) indicated good concurrent validity. The area under the ROC curve was 0.83, and the cut-off of 46 lead to 72.7% sensitivity and 77.1% specificity in identifying children with moderate/severe cognitive delay (MDI<70). Negative predictive value was 96.6 (90.3-99.3). Screening through PARCA-R would reduce the number of children with MDI≥70 undergoing BSID-II or equivalent standardized tool from 109 to 25. CONCLUSIONS The Italian version of PARCA-R retains good discriminative power for identifying cognitive delay in 2-year very preterm children. It is well accepted by parents, and represents a valid and efficient alternative for developmental screening and outcome measurement.

Abstract
INTRODUCTION Although important new strategies have improved outcomes for very preterm infants, males have greater mortality/morbidity than females. We investigated whether the excess of adverse later effects in males operated through poorer neonatal profile or if there was an intrinsic male effect. RESULTS Male sex was significantly associated with higher birth weight, death or oxygen dependency (72% vs. 61%, boys vs. girls), hospital stay (97 vs. 86 days), pulmonary hemorrhage (15% vs. 10%), postnatal steroids (37% vs. 21%), and major cranial ultrasound abnormality (20% vs. 12%). Differences remained significant after adjusting for birth weight and gestation. At follow-up, disability, cognitive delay, and use of inhalers remained significant after further adjustment. DISCUSSION We conclude that in very preterm infants, male sex is an important risk factor for poor neonatal outcome and poor neurological and respiratory outcome at follow-up. The increased risks at follow-up are not explained by neonatal factors and lend support to the concept of male vulnerability following preterm birth. METHODS Data came from the United Kingdom Oscillation Study, with 797 infants (428 boys) born at 23-28 wk gestational age. Thirteen maternal factors, 8 infant factors, 11 acute outcomes, and neurological and respiratory outcomes at follow-up were analyzed. Follow-up outcomes were adjusted for birth and neonatal factors sequentially to explore mechanisms for differences by sex.

Abstract
AIM The collection of data on longer-term neurodevelopmental outcomes within large neonatal randomized controlled trials by trained assessors can greatly increase costs and present many operational difficulties. The aim of this study was to develop a more practical alternative for identifying major cognitive delay in infants at the age of 24 months, based on parental reports. METHOD A sample of 476 infants (206 female, 270 male) previously diagnosed with neonatal sepsis (mean birthweight 1329g [SD 865g], mean gestational age at birth 28.7wks [SD 4.5wks]) from the International Neonatal Immunotherapy Study were assessed using the Parent Report of Children's Abilities - Revised and the Bayley Scales of Infant Development, 2nd edition. Logistic regression was used to model the association between the risk of major cognitive delay (i.e. Bayley Scales of Infant Development Mental Development Index <55) and the Parent Report of Children's Abilities - Revised data. RESULTS The receiver operating characteristic curves for a number of predictive models were constructed - each achieved an area under the curve of at least 90%. The sensitivity, specificity, positive predictive value, and negative predictive value of a number of points on the receiver operating characteristic curves are presented. INTERPRETATION The Parent Report of Children's Abilities - Revised is a practical tool for identifying major cognitive delay in infants at 24 months.

Abstract
AbstractThe Twins' Early Development Study (TEDS) is a large-scale longitudinal study of twins from early childhood through adolescence. Since its conception, TEDS has had as its focus the study of problematic development within the context of normal variation, mainly in the development of language, cognitive and academic abilities and behavior problems from multivariate quantitative and molecular genetic perspectives. TEDS twins have been assessed at 2, 3, 4, 7, 9, 10 and (currently) 12 years of age, and DNA collected from more than 12,000 children. Identified from birth records of twins born in the United Kingdom between 1994 and 1996, more than 15,000 pairs of twins originally enrolled in TEDS, and well over 13,000 pairs — representative of the UK population — remain involved in the study to date. Similar to many other twin and adoption studies, TEDS data indicate that both genetic and environmental influences are important in nearly all areas of behavioral development. Multivariate genetic analyses allow researchers to go beyond this basic nature–nurture question, and TEDS results suggest that, especially in the area of learning abilities and disabilities, genes are generalists and environments are specialists. That is, genes largely contribute to similarity in performance within and between learning abilities and disabilities and across age, whereas the environment contributes to differences in performance. Quantitative genetic findings such as these chart the course for molecular genetic research. The TEDS dataset is proving valuable in genome-wide association research that tries to identify some of the many genes responsible for the ubiquitous heritability of behavior.

Abstract
BACKGROUND Among very low birth weight (VLBW) infants, early neonatal hyperglycemia is common and is associated with increased risks for death and major morbidities. It is uncertain whether hyperglycemia per se is a cause of adverse clinical outcomes or whether outcomes can be improved by preventing hyperglycemia. OBJECTIVES To assess effects on clinical outcomes of interventions for preventing hyperglycemia in VLBW neonates receiving full or partial parenteral nutrition. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, issue 4 of 12, 2011; MEDLINE (1966 to April 2011); EMBASE (1980 to April 2011); CINAHL (1982 to Nov 2008); abstracts of Pediatric Academic Societies 2000 to 2011 and European Society for Pediatric Research 2005 to 2010. SELECTION CRITERIA Randomized or quasi-randomized controlled trials of interventions for prevention of hyperglycemia in neonates with birth weight < 1500 g or gestational age < 32 wk. DATA COLLECTION AND ANALYSIS Two review authors independently selected studies for eligibility and extracted data on study design, methods, clinical features, and treatment outcomes. Included trials were assessed for blinding of randomization, intervention and outcome measurement, and completeness of follow-up. Treatment effect measures for categorical outcomes were relative risk and risk difference, and for continuous outcomes, mean difference, each with their 95% confidence intervals. MAIN RESULTS We detected four eligible trials. Two trials compared lower versus higher rates of glucose infusion in the early postnatal period. These trials were too small to assess effects on mortality or major morbidities. Two trials, one a moderately large multicentre trial (NIRTURE, Beardsall 2008), compared insulin infusion with standard care. Insulin infusion reduced hyperglycemia but increased death before 28 days and hypoglycemia. Reduction in hyperglycemia was not accompanied by significant effects on major morbidities; effects on neurodevelopment are awaited. AUTHORS' CONCLUSIONS Glucose infusion rate: There is insufficient evidence from trials comparing lower with higher glucose infusion rates to inform clinical practice. Large randomized trials are needed, powered on clinical outcomes including death, major morbidities and adverse neurodevelopment.Insulin infusion: The evidence reviewed does not support the routine use of insulin infusions to prevent hyperglycemia in VLBW neonates. Further randomized trials of insulin infusion may be justified. They should enrol extremely low birth weight neonates at very high risk for hyperglycemia and neonatal death. They might use real time glucose monitors if these are validated for clinical use. Refinement of algorithms to guide insulin infusion is needed to enable tight control of glucose concentrations within the target range.

Abstract
Zusammenfassung. Mit der Konstruktion und Validierung eines Fragebogens zu kognitiven Prozessen bei 4- bis 6-jährigen Kindern (KOPKI 4-6) soll das diagnostische Inventar zur Erfassung kognitiver Funktionen bei Vorschulkindern ergänzt werden. Der KOPKI 4-6 erfasst mit 98 Items die sechs Bereiche Sprache, Gedächtnis, Visuell-räumliche Fähigkeiten, Allgemeine Kognition, Aufmerksamkeit und Selbständigkeit. Anhand von Normierungsstichproben (N = 522) wurden alters- und geschlechtsspezifische Normen abgeleitet. Die interne Konsistenz und die Split-Half-Reliabilitäten erwiesen sich als hoch. Signifikante Korrelationen zwischen der Skalen des KOPKI 4-6 und parallel durchgeführten Intelligenztests (n = 154) belegten Kriterienvalidität. Die differentielle Validität wurde anhand klinischer Gruppen mit Sprachentwicklungsstörungen, Aufmerksamkeitsstörungen und kombinierten Entwicklungsstörungen untersucht (n = 104). Eine multivariate Varianzanalyse zeigte signifikante Unterschiede zwischen den klinischen Gruppen. Der KOPKI 4-6 erweist sich damit als ein praktikables Verfahren, das zur Diagnose kognitiver Prozesse bei kleinen Kindern eingesetzt werden und Hinweise auf relevante Stärken oder Schwächen in Teilbereichen der kognitiven Entwicklung geben kann.

Abstract
BACKGROUND Research has highlighted a series of persistent deficits in cognitive ability in preterm low-birth-weight children. Language and attention problems are among these deficits, although the nature of the relation between attention and language in early development is not well known. This study represents a preliminary attempt to shed light on the relations between attention problems and language development in preterm low-birth-weight children. METHODS The aim of this study was to analyse reciprocal influences between language and attention problems from 18 to 36 months. We used maternal reports on attention problems and language ability referring to a sample of 1288 premature low-birth-weight infants, collected as part of the Norwegian Mother and Child Cohort Study (MoBa). A sample of children born full-term was used as the control group (N = 37010). Cross-lagged panel analyses were carried out to study reciprocal influences between attention problems and language. RESULTS Language ability at 18 months did not significantly predict attention problems at 36 months, adjusting for attention problems at 18 months. Attention problems at 18 months significantly predicted changes in language ability from 18 to 36 months, pointing to a precursor role of attention in relation to language in children born preterm. Gender, age corrected for prematurity, and mother's education emerged as important covariates. CONCLUSIONS Preliminary evidence was found for a precursor role of early attention problems in relation to language in prematurity. This finding can contribute to a better understanding of the developmental pathways of attention and language and lead to better management of unfavourable outcomes associated with co-morbid attention and language difficulties.

Abstract
Our goals were to (1) validate the parental Ages and Stages Questionnaires (ASQ) as a screening tool for psychomotor development among a cohort of ex-premature infants reaching 2 years, and (2) analyse the influence of parental socio-economic status and maternal education on the efficacy of the questionnaire. A regional population of 703 very preterm infants (<35 weeks gestational age) born between 2003 and 2006 were evaluated at 2 years by their parents who completed the ASQ, by a pediatric clinical examination, and by the revised Brunet Lezine psychometric test with establishment of a DQ score. Detailed information regarding parental socio-economic status was available for 419 infants. At 2 years corrected age, 630 infants (89.6%) had an optimal neuromotor examination. Overall ASQ scores for predicting a DQ score ≤85 produced an area under the receiver operator curve value of 0.85 (95% Confidence Interval:0.82–0.87). An ASQ cut-off score of ≤220 had optimal discriminatory power for identifying a DQ score ≤85 with a sensitivity of 0.85 (95%CI:0.75–0.91), a specificity of 0.72 (95%CI:0.69–0.75), a positive likelihood ratio of 3, and a negative likelihood ratio of 0.21. The median value for ASQ was not significantly associated with socio-economic level or maternal education. ASQ is an easy and reliable tool regardless of the socio-economic status of the family to predict normal neurologic outcome in ex-premature infants at 2 years of age. ASQ may be beneficial with a low-cost impact to some follow-up programs, and helps to establish a genuine sense of parental involvement.

Abstract
OBJECTIVE To examine the long-term effects of fluconazole prophylaxis in extremely low birth weight infants. STUDY DESIGN Neurodevelopmental status and quality of life of survivors from a randomized, placebo-controlled trial of fluconazole prophylaxis were evaluated at 8 to 10 years of life using the Vineland Adaptive Behavior Scales-II (VABS-II) and the Child Health Questionnaire Parent-Completed Form 28 (CHQ-PF28), respectively. RESULTS VABS-II Domain Scores for the fluconazole-treated (n = 21; 9.1 ± 0.7 years) compared with the placebo group (n = 17; 9.3 ± 0.8 years) were similar for communication [94.6 (±14.8) versus 92.6 (±12.6), P = .65], daily living skills [87.9 (±10.6) versus 87.4 (±9.3), P = .89], socialization [97.2 (±9.2) versus 94.4 (±7.9), P = .31], and motor skills [92.1 (±17.8) versus 95.1 (±14.6), P = .57]. Internalizing and externalizing behaviors and maladaptive behavior index were also similar. The CHQ-PF28 revealed no differences between the two groups regarding quality of life. Survivors were also happy or satisfied with school (90% versus 100%, P = .49), friendships (90% versus 88%, P = 1.00), and life (95% versus 100%, P = 1.00). Self esteem scores were 87.3 ± 15.7 versus 89.7 ± 10.4 (P = .59). There were also no differences between groups regarding emotional difficulties or behavior problems. CONCLUSIONS Fluconazole prophylaxis for the prevention of invasive Candida infections is safe in extremely low birth weight infants and does not appear to be associated with any long-term adverse effects on neurodevelopment and quality of life at 8 to 10 years of life.

Abstract
OBJECTIVE To examine differences in feeding among children with cerebral palsy (CP) who varied in the severity of their oral motor involvement; to examine longitudinal change in feeding behaviours for different severity groups. METHOD Twenty-three children with CP participated (mean age = 4.53 years at the first time point). Feeding data were collected from parent questionnaires at 6 month intervals over 30 months. RESULTS Significant differences were observed among severity groups for all feeding variables except coughing and choking during meals. Only one variable, coughing, showed significant change over time. CONCLUSIONS Children with CP who had severe oral-motor involvement had marked and pervasive feeding difficulties which showed some fluctuation with time, but generally were stable. Children with CP who did not have oral motor involvement and those who had mild-moderate involvement also showed little-to-no change over time and had fewer problems than those in the severe group.

Abstract
PURPOSE In this study, the authors proposed and tested a preliminary speech and language classification system for children with cerebral palsy. METHOD Speech and language assessment data were collected in a laboratory setting from 34 children with cerebral palsy (CP; 18 male, 16 female) with a mean age of 54 months (SD = 1.8). Measures of interest were vowel area, speech rate, language comprehension scores, and speech intelligibility ratings. RESULTS Canonical discriminant function analysis showed that 3 functions accounted for 100% of the variance among profile groups, with speech variables accounting for 93% of the variance. Classification agreement varied from 74% to 97% based on 4 different classification paradigms. CONCLUSIONS The results of this study provide preliminary support for the classification of speech and language abilities of children with CP into 4 initial profile groups. Further research is necessary to validate the full classification system.

Abstract
Background During severe acute respiratory syndrome (SARS) outbreak in Toronto, outpatient clinics at SickKids Hospital were closed to prevent further disease transmission. In response, a decision was made by the neonatal neuro-developmental follow up (NNFU) clinic staff to select patients with scheduled appointments to have a mail/telephone assessment using Ages and Stages Questionnaire (ASQ) or to postpone/skip their visit. The objective of this study was to compare the developmental assessment and its outcome in two groups of NNFU clinic patients, SARS versus non-SARS, over three standard clinic appointments. Methods We compared the diagnostic accuracy (identification of developmental delay), and patient management (referral for therapy or communication of a new diagnosis) of the strategies used during SARS, April/May 2003, to the standard assessment methods used for patients seen in April/May 2005 (non-SARS). In all cases data were obtained for 3 patient visits: before, during and after these 2 months and were compared using descriptive statistics. Results There were 95 patients in the SARS group and 99 non-SARS patients. The gestational age, sex, entry diagnosis and age at the clinic visit was not different between the groups. The NNFU clinic staff mailed ASQ to 27 families during SARS, 17 (63%) were returned, and 8 of the 17 were then contacted by telephone. Criteria used to identify infants at risk selected for either mailed ASQ or phone interviews were not clearly defined in the patients' charts. There was a significant under identification of developmental delay during SARS (18% versus 45%). Of those who responded to the mailed questionnaire, referrals for therapy rates were similar to non-SARS group. The lost to follow up rate was 24% for the SARS group compared with 7% for non-SARS. There was no difference in the overall rate of developmental delay in the two groups as identified at the 'after' visit. Conclusions Poor advanced planning led to a haphazard assessment of patients during this infectious disease outbreak. Future pandemic plans should consider planning for outpatient care as well as in hospital management of patients.

Abstract
AIM To validate an Italian parental questionnaire designed to evaluate the neuropsychological and behavioural developmental status of 4-year-olds and identify children in need of further evaluation. METHODS The questionnaire (Questionario per la valutazione dello Sviluppo di bambini a 4 anni - Genitori (QS4-G) ) consisted of 93 questions divided into 10 areas: language, visual-motor abilities, memory/attention, fine and gross motor and self-help abilities, lateralisation, social skills, stress, sleep, alimentation and evacuation. It was distributed to 263 parents of 4-year-olds: 94 healthy preterm (gestational age <33 weeks and/or <1500 g, without major neurosensory damage); 44 children with developmental disorders and 125 children with typical development. Cognitive and neuropsychological evaluations were performed using standardised tests. RESULTS The internal consistency of the areas was adequate (Cronbach's alpha: 0.69-0.79). The correlation coefficients (r=|0.30|-|0.68|) with standardised tests (Griffiths, Vineland and neuropsychological tests) indicated a good concurrent validity. The receiver operating characteristic curve, for predicting a Griffiths Quotient less than 81, showed an area under the curve of 0.90 and a high diagnostic and discriminatory capacity (sensitivity of 0.88 and specificity of 0.84) for the optimal cut-off (value 48.4). CONCLUSION The QS4-G seems to be a valid tool for identifying 4-year-old children at risk for low or borderline cognitive development and/or problematic behaviour who need a complete assessment. It can describe individual neuropsychological profiles. QS4-G is not a diagnostic tool. It is useful for outcome studies in preterm children and in other pathologies. It could also be useful for preschooler prevention programmes.

Abstract
Abstract Background This study assessed the concurrent validity of the Ages and Stages Questionnaire (ASQ) compared with Bayley Scales of Infant Development II (BSID II) amongst children aged 24 months. Methods Data were collected from 53 infants and mothers who participated in the New York State Angler Cohort Child Development Study. Parents completed the 24-month ASQ to assess communication, personal-social, problem-solving ability, and fine and gross motor control. The BSID II was administered by a clinical psychologist at the 24-month home visit for cognitive and psychomotor assessment. The ASQ was scored using age-specific norms of <2 SDs below any domain mean to define failure. A BSID II score of <85 indicated mild or severe delay, while a score of <70 suggested a severe delay. Results Scores on the ASQ communication and personal-social domains were moderately correlated with the BSID II Mental Scale (R= 0.52, P < 0.001; R= 0.45, P < 0.01) and ASQ gross motor with the BSID II Motor Scale (R= 0.46, P < 0.01), whereas ASQ problem-solving and fine motor domains were not significantly correlated with BSID II scores. The ASQ had a sensitivity of 100% and specificity of 87% at 24 months (n= 40) for severely delayed status. Conclusions Results suggest the ASQs provide a simple, valid, and cost-effective method for clinicians and field-based researchers to reduce the number of standardized assessments required to identify developmentally delayed infants at age 24 months. Future studies should further assess the validity of the ASQs in larger, more diverse populations of infants.

Abstract
BACKGROUND Existing evidence indicates that once mature neonates with severe cardio-respiratory failure become eligible for Extra Corporeal Membrane Oxygenation (ECMO) their chances of intact survival are doubled if they actually receive ECMO. However, significant numbers survive with disability. NEST is a multi-centre randomised controlled trial designed to test whether, in neonates requiring ECMO, cooling to 34 degrees C for the first 48 to 72 hours of their ECMO course leads to improved later health status. Infants allocated to the control group will receive ECMO at 37 degrees C throughout their course, which is currently standard practice around the world. Health status of both groups will be assessed formally at 2 years corrected age. METHODS/DESIGN All infants recruited to the study will be cared for in one of the four United Kingdom (UK) ECMO centres. Babies who are thought to be eligible will be assessed by the treating clinician who will confirm eligibility, ensure that consent has been obtained and then randomise the baby using a web based system, based at the National Perinatal Epidemiology Unit (NPEU) Clinical Trials Unit. Trial registration.Babies allocated ECMO without cooling will receive ECMO at 37 degrees C +/- 0.2 degrees C. Babies allocated ECMO with cooling will be managed at 34 degrees C +/- 0.2 degrees C for up to 72 hours from the start of their ECMO run. The minimum duration of cooling will be 48 hours. Rewarming (to 37 degrees C) will occur at a rate of no more than 0.5 degrees C per hour. All other aspects of ECMO management will be identical. PRIMARY OUTCOME Cognitive score from the Bayley Scales of Infant and Toddler Development, 3rd edition (Bayley-III) at age of 2 years (24 - 27 months). DISCUSSION For the primary analysis, children will be analysed in the groups to which they are assigned, comparing the outcome of all babies allocated to "ECMO with cooling" with all those allocated to "ECMO" alone, regardless of deviation from the protocol or treatment received. For the primary outcome the analysis will compare the mean scores for each group of surviving babies. The rationale for this choice of primary analysis is to give a fair representation of the average ability of assessable children, accepting the limitation that excluding deaths might impose.The consistency of the effect of cooling on the group of babies recruited to the trial will be explored to see whether cooling is of particular help, or not, to specific subgroups of infants, using the statistical test of interaction. Therefore pre-specified subgroup analyses include: (i) whether the ECMO is veno-arterial or veno-venous; (ii) whether the child's oxygenation index at the time of recruitment is <60 or > or = 60; (iii) initial aEEG pattern shown on the cerebral function monitor, and (iv) primary diagnostic group. TRIAL REGISTRATION Current Controlled Trials ISRCTN72635512.

Abstract
OBJECTIVES To find out whether supplementation of formula milk by long-chain polyunsaturated fatty acids (LCPUFA) affects neurodevelopment at 18 months of age in term or preterm infants by an individual patient data (IPD) meta-analysis. MATERIALS AND METHODS Data of 870 children from 4 large randomised clinical trials for formula milk with and without LCPUFAs allowed for assessing the effect of LCPUFA with adjustment for potential confounders and extensive subgroup analysis on prematurity, LCPUFA source, and dosage. Any additional clinical trials examining the effect of LCPUFA supplementation on Bayley Scales of Infant Development at 18 months were regarded as relevant. Two relevant studies were identified by MEDLINE, but were not available to us. An IPD meta-analysis was performed with subgroup analyses by preterm delivery, very low birth weight (<1500 g), trials with higher amounts of docosahexaenoic acid (DHA) and arachidonic acid (AA), and specific sources of LCPUFA. The sample size of 870 children was sufficient to detect clinically relevant differences in Bayley Scales even in subgroups. RESULTS There were no significant differences in mental or psychomotor developmental indexes between LCPUFA-supplemented and control groups for all children or in subgroups. This was confirmed with adjustment for the possible confounders: sex, gestational age, birth weight, maternal age, and maternal smoking. The adjusted mean differences in mental developmental index and psychomotor developmental index for all of the children were -0.8 (95% confidence interval -2.8 to 1.2) and -1.0 (-2.7 to 0.7), respectively. CONCLUSIONS These data based on considerable sample size provide substantial evidence that LCPUFA supplementation of infant formula does not have a clinically meaningful effect on the neurodevelopment as assessed by Bayley scores at 18 months. Inclusion of all relevant data should not have led to differing conclusions except, possibly, for very-low-birth-weight infants.

Abstract
BACKGROUND The aim of the present study was to investigate the prediction of development among 6-, 18-, and 36-month-old infants on the Bayley Scale of Infant Development (BSID). METHODS One hundred infants were assessed using the BSID at 6 months; of these, 70 completed the 18 and 36 month assessment at follow up. RESULTS Multivariate regression and structural equation modeling were used to determine predictive validity in the mental and psychomotor developmental scales. Structural equation analysis also confirmed the conceptual scheme of the stability of development from 6 to 36 months for boys. Boys had a steadier overall developmental trajectory compared to girls. CONCLUSIONS The validity of BSID was consistent with previous studies. The language spurt in girls, however, from 6 to 18 months affected the stability of the BSID. Thus, the gender difference in language development should be considered in clinical assessment.

Abstract
BACKGROUND Among very low birth weight (VLBW) infants, early neonatal hyperglycemia is common and is associated with increased risks for death and major morbidities. It is uncertain whether hyperglycemia per se is a cause of adverse clinical outcomes or whether outcomes can be improved by preventing hyperglycemia. OBJECTIVES To assess effects on clinical outcomes of interventions for preventing hyperglycemia in VLBW neonates receiving full or partial parenteral nutrition. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, issue 4 2008; MEDLINE (1966 - Nov 2008); EMBASE (1980 - Nov 2008); CINAHL (1982 - Nov 2008); abstracts of Pediatric Academic Societies 2000 - 2008 and European Society for Paediatric Research 2005 - 2008. SELECTION CRITERIA Randomized or quasi-randomized controlled trials of interventions for prevention of hyperglycemia in neonates with birth weight < 1500 g or gestational age < 32 wk DATA COLLECTION AND ANALYSIS Two review authors independently selected studies for eligibility and extracted data on study design, methods, clinical features, and treatment outcomes. Included trials were assessed for blinding of randomization, intervention and outcome measurement, and completeness of follow-up. Treatment effect measures for categorical outcomes were relative risk and risk difference, and for continuous outcomes, mean difference, each with their 95% confidence intervals. MAIN RESULTS We detected four eligible trials. Two trials compared lower vs. higher rates of glucose infusion in the early postnatal period. These trials were too small to assess effects on mortality or major morbidities. Two trials, one a moderately large multicentre trial (NIRTURE, Beardsall 2008), compared insulin infusion with standard care. Insulin infusion reduced hyperglycemia but increased death before 28 days and hypoglycemia. Reduction in hyperglycemia was not accompanied by significant effects on major morbidities; effects on neurodevelopment are awaited. AUTHORS' CONCLUSIONS Glucose infusion rate: There is insufficient evidence from trials comparing lower with higher glucose infusion rates to inform clinical practice. Large randomized trials are needed, powered on clinical outcomes including death, major morbidities and adverse neurodevelopment.Insulin infusion: The evidence reviewed does not support the routine use of insulin infusions to prevent hyperglycemia in VLBW neonates. Further randomized trials of insulin infusion may be justified. They should enrol extremely low birth weight neonates at very high risk for hyperglycemia and neonatal death. They might use real time glucose monitors if these are validated for clinical use. Refinement of algorithms to guide insulin infusion is needed to enable tight control of glucose concentrations within the target range.

Abstract
Studies of prematurely born infants contain a relatively large percentage of multiple births, so the resulting data have a hierarchical structure with small clusters of size 1, 2 or 3. Ignoring the clustering may lead to incorrect inferences. The aim of this study was to compare statistical methods which can be used to analyse such data: generalised estimating equations, multilevel models, multiple linear regression and logistic regression. Four datasets which differed in total size and in percentage of multiple births (n = 254, multiple 18%; n = 176, multiple 9%; n = 10 098, multiple 3%; n = 1585, multiple 8%) were analysed. With the continuous outcome, two-level models produced similar results in the larger dataset, while generalised least squares multilevel modelling (ML GLS 'xtreg' in Stata) and maximum likelihood multilevel modelling (ML MLE 'xtmixed' in Stata) produced divergent estimates using the smaller dataset. For the dichotomous outcome, most methods, except generalised least squares multilevel modelling (ML GH 'xtlogit' in Stata) gave similar odds ratios and 95% confidence intervals within datasets. For the continuous outcome, our results suggest using multilevel modelling. We conclude that generalised least squares multilevel modelling (ML GLS 'xtreg' in Stata) and maximum likelihood multilevel modelling (ML MLE 'xtmixed' in Stata) should be used with caution when the dataset is small. Where the outcome is dichotomous and there is a relatively large percentage of non-independent data, it is recommended that these are accounted for in analyses using logistic regression with adjusted standard errors or multilevel modelling. If, however, the dataset has a small percentage of clusters greater than size 1 (e.g. a population dataset of children where there are few multiples) there appears to be less need to adjust for clustering.

Abstract
AIMS To assess neurodevelopmental outcome at 2 years for neonatal intensive care unit (NICU) admissions compared with controls, and to trial a parent-reporting scheme. METHODS All infants admitted to the NICU at Christchurch Women's Hospital over a 12-month period and whose parents were domiciled in a defined geographical region were eligible for study, together with every eighth term infant not admitted (to a total of 300). Parents completed a two-page questionnaire on their child's 2nd birthday. All infants <28 weeks gestation and a random 300 NICU admissions and 108 controls underwent a paediatric examination and Bayley II assessment at 2 years of age. RESULTS A total of 387 NICU infants (86% eligible) and 306 controls were enrolled. At 2 years of age, 276 NICU infants (89% survivors) and 94 controls (87%) had some follow up. For infants of <33 weeks, 33-36 weeks, > or =37 weeks gestation and controls, the percentage >1 SD below the mean on the Bayley Mental Development Index scales were 33.3, 36.5, 44.6 and 24.1, respectively (P= 0.03); on the Psychomotor Developmental Index scales were 30.0, 29.1, 41.1 and 19.5 (P= 0.02) and the percentage with any cerebral palsy were 11.1, 2.8, 5.2 and 1.2. CONCLUSIONS At 2 years of age, NICU graduates have more developmental problems than controls across a range of measures. In many cases, term NICU graduates have the least favourable outcome. There was only moderate agreement between parents' reporting of moderate or severe developmental disability by means of a questionnaire, compared with professionals (kappa statistic 0.38), with parents tending to underestimate problems.

Abstract
BACKGROUND Infants who suffer hypoxic-ischaemic encephalopathy (HIE) at birth are at increased risk of developmental disability. In this at-risk population, reliable, inexpensive and early identification of those children who are likely to require formal developmental assessment and intervention is needed. AIM To evaluate the ability of the Ages and Stages Questionnaire (ASQ) to detect developmentally delayed children in an Australian population of infants who suffered HIE at birth. METHODS Fifty-five children who survived HIE were followed until 12-14 months of age. Test characteristics were calculated to examine the ability of the ASQ to appropriately identify developmentally delayed infants against this study's 'gold standard': the Bayley Scales of Infant Development II. RESULTS Comparing the ASQ with the Bayley Scales of Infant Development II, the questionnaire had the following test characteristics: sensitivity 92%, specificity 95%, positive predictive value 92%, negative predictive value 95% when used to detect severe developmental delay; and sensitivity 67%, specificity 93%, positive predictive value 92%, negative predictive value 68% when used to detect both severe and mild developmental delay. However, the ASQ used at standard cut-offs failed to detect any of the children with mild delay. CONCLUSIONS The ASQ is extremely effective for the detection of severe developmental delay in children who have suffered HIE at birth. Its capacity to identify those with milder delay is limited. The ability of the test to detect only those with severe developmental delay means that the ASQ is of little value as a screening tool in this population.

Abstract
Parental questionnaires are inexpensive alternatives to standardized testing for outcome measurement. The Parent Report of Children's Abilities has previously been revised (PARCA-R) and validated for use with very-preterm infants at 2 years of age. This study revalidated the PARCA-R for assessing cognition in a larger and more inclusive sample of preterm infants. One hundred and sixty-four children (82 males, 82 females) of <32 weeks' gestation (median 29wks, interquartile range [IQR] 28-30wks); and median birthweight 1200g (IQR 925-1463g) were evaluated using the Mental Development Index (MDI) of the Bayley Scales of Infant Development - 2nd edition (BSID-II) at 2 years' corrected age. Parents completed the PARCA-R questionnaire. Significant correlations between PARCA-R Parent Report Composite (PRC) scores and MDI scores (r=0.77, 95% confidence interval [CI] 0.69-0.82, p<0.01) demonstrated concurrent validity. A receiver operating characteristic-determined PRC cut-off of <44 had optimal discriminatory power (area under curve 0.92) for identifying MDI <70, with 85% sensitivity (95% CI 0.58-0.96), 87% specificity (95% CI 0.81-0.92), 98% negative predictive value (95% CI 0.95-1), and 37% positive predictive value (95% CI 0.22-0.54). The PARCA-R has good concurrent validity and diagnostic utility for identifying cognitive delay in very-preterm infants at 2 years of age. It is useful for outcome measurement, developmental screening, and facilitating parental involvement at follow-up.

Abstract
Routine neurodevelopmental follow-up is crucial in high-risk populations, such as those born very preterm. Even in the absence of severe neurosensory impairment, very preterm children are at risk for a range of long-term cognitive, motor, and learning deficits. Infant developmental assessments are typically carried out at 2 years of age for both clinical and research purposes, and they are crucial for outcome monitoring. We review psychometric tests of infant developmental functioning most widely used as outcome measures for very preterm infants and other high-risk populations. We also consider parent-based assessments and methodological issues pertaining to the use of these tools in large-scale research studies and in outcome monitoring in this population.

Abstract
AIM To evaluate performance of the Ages and Stages Questionnaires (full ASQ), and a shortened version (short ASQ), in detecting children with severe neurosensory disability in the Magpie Trial follow-up study. METHODS All children, born to women in the Magpie Trial and selected for follow-up, with a completed full 30 items and/or short 9-items ASQ were included in this analysis. Sensitivity and specificity, corrected for verification bias, were computed to assess detection ability. RESULTS Of the 2046 children who completed a full ASQ, 406 (19.8%) failed the assessment, 54 of whom had confirmed neurosensory disability. Adjusted sensitivity and specificity (95% confidence intervals) were 87.4% (62.9-96.6%), and 82.3% (80.5-83.9%), respectively. Two of the five domains in the full ASQ (Fine Motor and Problem Solving) contributed little to detection ability. Sensitivity and specificity for the short ASQ were 69.2% and 95.7%, respectively. CONCLUSIONS Sensitivity of the full ASQ for severe neurosensory disability is generally good, and does not appear to be much reduced by restricting questions to three out of the five domains. The short ASQ reported here reduced performance, although this might be improved by a different choice of questions or scoring system.

Abstract
Language development is often slower in preterm children compared with their term peers. We investigated factors associated with vocabulary acquisition at 2 years in a cohort of children born at 28 weeks' gestation or less. For children entered into the United Kingdom Oscillation Study, language development was evaluated by using the MacArthur-Bates Communicative Development Inventories score, completed by parents as part of a developmental questionnaire. The effect of demographic, neonatal, socioeconomic factors, growth, and disability were investigated using multifactorial random effects modelling. Questionnaires were returned by 288 participants (148 males, 140 females). The mean number of words vocalized was 42 (SD 29). Multifactorial analysis showed only four factors were significantly associated with vocabulary acquisition. These were: (1) level of disability (mean words: no disability, 45; other disability, 38; severe disability, 30 [severe disability is defined as at least one extreme response in one of the following clinical domains: neuromotor, vision, hearing, communication, or other physical disabilities]; 95% confidence interval [CI] for the difference between no and severe disability 7- 23); (2) sex (39 males, 44 females; 95% CI 0.4-11); (3) length of hospital stay (lower quartile, 47; upper quartile, 38; 95% CI -12 to -4); and (4) weight SD score at 12 months (lower quartile, 39; upper quartile, 44; 95% CI 1-9). There was no significant association between gestational age and vocabulary after multifactorial analysis. There was no significant effect of any socioeconomic factor on vocabulary acquisition. We conclude that clinical factors, particularly indicators of severe morbidity, dominate the correlates of vocabulary acquisition at age 2 in children born very preterm.

Abstract
To identify a simple and effective screening instrument for language delays in 3-year-old children the reliability, validity, and accuracy of five screening instruments were examined. A postal questionnaire sent to parents of 11423 children included the Dutch version of the General Language Screen (GLS), the Van Wiechen (VW) items, the Language Screening Instrument for 3- to 4-year-olds, consisting of a parent form (LSI-PF) and a child test (LSI-CT), and parents' own judgement of their child's language development on a visual analogue scale (VAS). The response rate was 78% or 8877 children. Reliability (internal consistency) was found to be acceptable (alpha=0.67-0.72) for all instruments. Significant correlations between the screening instruments (r=0.29-0.55, p<0.01) indicated good concurrent validity. Accuracy was estimated by the sensitivity, specificity, and receiver operating characteristic (ROC) curves against two reference tests based on parent report and specialists' judgement. If the test would classify approximately 5% of the population as screen-positive, the mean sensitivity was 50%; assigning between 20% and 30% of the population as screen-positive, the mean sensitivity was 77%. The sensitivity was lowest for the LSI-CT (range 43-62%), whereas short instruments like the LSI-PF, VW, and the one-item VAS exhibited high levels of sensitivity (range 50-86%). The area under the ROC curves, ranged from 0.75 to 0.87. Apparently, short and simple parent report instruments like the LSI-PF and the one-item VAS perform remarkably well in detecting language delays in preschool children.

Abstract
BACKGROUND Smoking in pregnancy remains a public health challenge. Nicotine replacement therapy (NRT) is effective for smoking cessation in non-pregnant people, but because women metabolise nicotine and cotinine much faster in pregnancy, it is unclear whether this will be effective for smoking cessation in pregnancy. The NHS Health Technology Assessment Programme (HTA)-funded smoking, nicotine and pregnancy (SNAP) trial will investigate whether or not nicotine replacement therapy (NRT) is effective, cost-effective and safe when used for smoking cessation by pregnant women. METHODS/DESIGN Over two years, in 5 trial centres, 1050 pregnant women who are between 12 and 24 weeks pregnant will be randomised as they attend hospital for ante-natal ultrasound scans. Women will receive either nicotine or placebo transdermal patches with behavioural support. The primary outcome measure is biochemically-validated, self-reported, prolonged and total abstinence from smoking between a quit date (defined before randomisation and set within two weeks of this) and delivery. At six months after childbirth self-reported maternal smoking status will be ascertained and two years after childbirth, self-reported maternal smoking status and the behaviour, cognitive development and respiratory symptoms of children born in the trial will be compared in both groups. DISCUSSION This trial is designed to ascertain whether or not standard doses of NRT (as transdermal patches) are effective and safe when used for smoking cessation during pregnancy.

Abstract
AIM To assess developmental deficit in children born at gestational age (GA) < 26 wk using a parental questionnaire and to use regression analysis to study a cohort born in 1999-2003. PATIENTS AND METHODS Three groups were studied: group 1, GA < 26 wk; group 2, GA 26-27 wk; group 3, children born at term. The Ages & Stages Questionnaire (ASQ) was used. The parents of each child were mailed an age-specific questionnaire between November 2004 and April 2005. The term children were used as a reference to calculate a standard deviation score (ASQ-SDS) for each child in the two preterm groups. RESULTS Seventy-five per cent of the questionnaires were returned (group 1: n=61; group 2: n=57; group 3: n=72). The age at scoring ranged from 12 to 60 mo (mean 32.8 mo). After correction for parental education, 22% of the children born at GA < 26 wk and 13% of those at GA 26-27 wk had an ASQ-SDS below -2. Chronic lung disease of prematurity was associated with developmental deficit (mean difference -1.1 ASQ-SDS, p=0.004). CONCLUSION The ASQ identified a significant developmental deficit in the children born extremely preterm. The rate of 22%, however, in children born at GA < 26 wk is reassuring.

Abstract
BACKGROUND The long term outcome of children entered into neonatal trials of high frequency oscillatory ventilation (HFOV) or conventional ventilation (CV) has been rarely studied. OBJECTIVE To evaluate respiratory and neurodevelopmental outcomes for children entered into the United Kingdom Oscillation Study, which was designed to evaluate these outcomes. METHODS Surviving infants were followed until 2 years of age corrected for prematurity. Study forms were completed by local paediatricians at routine assessments, and parents were asked to complete a validated neurodevelopmental questionnaire. RESULTS Paediatricians' forms were returned for 73% of the 585 surviving infants. Respiratory symptoms were common in all infants, and 41% had received inhaled medication. Mode of ventilation had no effect on frequency of any symptoms. At 24 months of age, severe neurodevelopmental disability was present in 9% and other disabilities in 38% of children, but the prevalence of disability was similar in children who received HFOV or CV (relative risk 0.93; 95% confidence interval 0.74 to 1.16). The prevalence of disability did not vary by gestational age, but boys were more likely to have overall disability. Developmental scores were unaffected by mode of ventilation (relative risk 1.13; 95% confidence interval 0.78 to 1.63) and were lower in infants born before 26 weeks gestation compared with babies born at 26-28 weeks. CONCLUSIONS Initial mode of ventilation in very preterm infants has no impact on respiratory or neurodevelopmental morbidity at 2 years. HFOV and CV appear equally effective for the early treatment of respiratory distress syndrome.

Abstract
Marked differences are seen in neurological and health status, intellectual functioning, school performance and behaviour between children born prematurely and those born at term. Assessment in later childhood has identified more subtle problems than the severe disability or sensory deficits readily identifiable at two years. These problems include learning disabilities, specific neuropsychological deficits in executive function, difficulties in visual-motor integration and perception, selective language impairment, motor coordination disorders, behaviour problems, attention deficit hyperactivity disorder (ADHD), and reduced educational achievement. Follow-up to school entry and beyond is thus required to determine the true prevalence and nature of the neurodevelopmental problems arising from preterm birth. Consensus about the assessment used, definitions of disability and health status, age of assessment and who undertakes it are necessary and should allow comparison across populations; this may help to maximise outcomes for children clearly at biological risk. Assessment of outcome for children born preterm beyond two years is required for counselling parents, planning health and education provision, for evaluation of services and to facilitate understanding of the longer term effects of preterm birth on brain development.

Abstract
Reviewing high risk infants after discharge to provide ongoing clinical care and to monitor later outcomes is an important role for neonatologists and paediatricians. Clinical need is the primary reason for such follow up but the process does provide additional opportunities, for example collecting information on later outcomes is vital for health care commissioning, and to determine the longer term effects of new medical treatments. Parents welcome the early identification of any problems in their infant and the opportunity for early intervention may improve outcomes in some circumstances. However, depending on the model adopted, follow up can be costly and this expenditure must be justified by considering the benefits obtained.

Abstract
Given the high risk for residual disability in preterm infants, outcome monitoring is a crucial function of neonatal care. Provision of neurodevelopmental follow-up to at least 2 years of age corrected for prematurity forms part of national recommendations for neonatal services. This should include a developmental assessment at 2 years to identify disability. Although screening tools are cost and time efficient measures, they are not diagnostic and have less utility in high-risk populations. In contrast, standardised developmental tests are ideally suited for follow-up purposes and have become widely accepted as outcome measures. We highlight the properties of standardised tests and review the most commonly used tools for assessment in infancy. We also outline a number of practical issues in the use of standardised tests with preterm infants in identifying morbidity and predicting later impairment. Parental reports are also discussed and key guidelines for developmental testing at 2 years are provided.

Abstract
During the past decade, major advances in maternal-fetal medicine and neonatology have resulted in unprecedented survival of very preterm babies. These babies represent a small fraction of infants born preterm, but present significant challenges with respect to respiratory, nutritional, and developmental vulnerabilities. Several efforts involving the UK, US, Canada, Australia, and the Netherlands have provided information on regional trends over time with respect to neonatal morbidities and neurodevelopmental outcomes through the first two years of life. Historically gross and fine motor, cognitive and communicative skills, vision and hearing performance have been the focus of assessment. Indicators of major neurodevelopmental disabilities at 2 years have included presence of severe neurosensory impairment, i.e. cerebral palsy, sensorineural hearing loss requiring aides, and blindness. In addition cognitive developmental disability has been generally defined as a Bayley MDI or developmental quotient <70, i.e. lower than 2 standard deviations below the mean. However these outcomes cannot reliably capture trajectories of resiliency as well as more complex developmental challenges in the domains of coordination, perception, attention, communication, and learning. Recently tools have become available for assessing functional status in gross motor, communicative, adaptive and social-emotional behaviours of imitation, regulation, and play. This review will describe the major progress in assessing early neurodevelopmental status of vulnerable survivors receiving new biomedical technologies, highlight challenges, and propose guidelines based on current best evidence.

METHODS The parents of 88 children born with a gestational age below 28 wk admitted to the neonatal intensive care unit (NICU) at Rigshospitalet, Copenhagen, were interviewed by telephone when their child was 1 y of age, corrected for preterm birth. A fully structured questionnaire on psychomotor function was used (Revised Prescreening Developmental Questionnaire (R-PDQ)). The parents of 30 children born at term without complications were interviewed for comparison. The interview was conducted by NICU staff. To validate the R-PDQ, parents of 22 children in the preterm group and parents of 19 children in the reference group conducted an Ages and Stages Questionnaire (ASQ) when their children had reached the age of 3-3(1/2) y. RESULTS The R-PDQ was easy to use by staff and well accepted by parents. The mean score in the preterm group was 14.9+/-3.9 vs 17.7+/-2.7 in the term group (p<0.001). Three children had developmental scores below-2 SD. The R-PDQ score was associated with the ASQ score 2 y later. CONCLUSION A structured questionnaire administrated by telephone is an alternative and usable tool for assessing neurodevelopmental deficit in children born extremely preterm. The mean developmental delay in the preterm group compared to the term group (about-1 SD) was close to expectations.

Abstract
BACKGROUND We aimed to determine how response to a parent-completed postal questionnaire measuring development, behaviour, impairment, and parental concerns and anxiety, varies in different European centres. METHODS Prospective cohort study of 3 year old children, with and without congenital toxoplasmosis, who were identified by prenatal or neonatal screening for toxoplasmosis in 11 centres in 7 countries. Parents were mailed a questionnaire that comprised all or part of existing validated tools. We determined the effect of characteristics of the centre and child on response, age at questionnaire completion, and response to child drawing tasks. RESULTS The questionnaire took 21 minutes to complete on average. 67% (714/1058) of parents responded. Few parents (60/1058) refused to participate. The strongest determinants of response were the score for organisational attributes of the study centre (such as direct involvement in follow up and access to an address register), and infection with congenital toxoplasmosis. Age at completion was associated with study centre, presence of neurological abnormalities in early infancy, and duration of prenatal treatment. Completion rates for individual questions exceeded 92% except for child completed drawings of a man (70%), which were completed more by girls, older children, and in certain centres. CONCLUSION Differences in response across European centres were predominantly related to the organisation of follow up and access to correct addresses. The questionnaire was acceptable in all six countries and offers a low cost tool for assessing development, behaviour, and parental concerns and anxiety, in multinational studies.
