Vallamkonda N, Bandyopadhyay T, Maria A. A Study of General Movement Assessment and Its Association With Neurodevelopmental Outcome at Age 12 to 15 Months Among Term Neonates With Hyperbilirubinemia. Pediatr Neurol 2024; 153:77-83. [PMID: 38341950 DOI: 10.1016/j.pediatrneurol.2023.12.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/11/2023] [Revised: 09/12/2023] [Accepted: 12/31/2023] [Indexed: 02/13/2024]
Abstract
BACKGROUND To determine the association between optimality score at term age and age three to five months and neurodevelopmental outcome among neonates with hyperbilirubinemia. METHODS Fifty infants with and without hyperbilirubinemia were enrolled. The motor repertoires of the infants were evaluated through general movement assessment (GMA) at term age and three to five months post-term. The association between the General Movement Optimality Score (GMOS), Motor Optimality Score (MOS), and Development Assessment Scale for Indian Infants (DASII) at age 12 to 15 months was also assessed. RESULTS During term age, the median GMOS was significantly lower among infants in the study group when compared with the control group (40 [29 to 42] vs 42 [42 to 42], P < 0.001). However, at age three to five months, there was no significant difference between the groups. Significantly higher number of neonates had abnormal motor repertoire at term age and age three to five months in the study group when compared with the control group (18 [36%] vs 2 [4%], P = 0.001, at term age and 6 [12.2%] vs 1 [2%], P =0.04, at age three to five months). Among neonates with hyperbilirubinemia, the median GMOS and MOS were significantly lower at term age and age three to five months in infants with motor and mental developmental quotient scores <85 when compared with ≥85. CONCLUSIONS GMA including GMOS and MOS performed in neonates with hyperbilirubinemia during the neonatal period and early infancy is associated with neurodevelopmental outcomes in the first year of life. GMA can help initiate early intervention in such neonates.

Abstract
AIM To assess the efficacy of post-hospital psychomotor therapy in the development of very preterm infants at nine and 24 months. METHODS We conducted a randomised controlled study at Toulouse Children's Hospital between 2008 and 2014 among preterm infants aged under 30 weeks. All infants in both groups could benefitt from physiotherapy to prevent motor disorders. The intervention group received 20 early post-hospital psychomotor therapy sessions. The development was assessed by the Bayley Scale Infant Development at nine and 24 months. RESULTS The intervention and control group contained 77 and 84 infants, respectively, with 57 infants in each group undergoing assessment at 24 months. Boys accounted for 56% of the population. Median gestational age was 28 weeks, range 25-29. The development scores at 24 months did not significantly differ between the randomisation groups. At 9 months, we observed improvements in global motricity (mean difference 0.9 point, p = 0.04) and fine motricity for the subgroup containing educationally underserved mothers (mean difference 1.6 point, p = 0.008). There was no significant difference in neuromotor functioning between the two groups. CONCLUSION The benefits of psychomotor therapy were short-lived and did not persist post-intervention. Our results and this organisational model encouraged us to persevere towards similar multi-professional care.

Abstract
OBJECTIVE This study was aimed to evaluate the impact of donor milk (DM) received in the first 28 days of life (DOL) on neurodevelopmental (ND) outcome at 20-months corrected age (CA) in very low birth weight (VLBW) infants. STUDY DESIGN A total of 84 infants born in 2011 to 2012 who received only mother's own milk (MOM) and/or preterm formula (PF) was compared with 69 infants born in 2013 to 2014 who received MOM and/or DM. Daily enteral intake of MOM, DM, and PF was collected through 28 DOL. ND outcomes were assessed with the Bayley-III. Multiple regression analyses adjusted for the effect of social and neonatal risk factors alongside era of birth on ND outcome. RESULTS Infants exposed to DM were born to older mothers (p < 0.01) and had higher incidence of severe brain injury (p = 0.013). Although DM group infants received first feed at earlier DOL (p < 0.001), there were no differences in MOM intake at DOL 14 or 28 between the two groups. In regression analyses, DM group did not predict 20-month ND outcome. CONCLUSION There were no differences in ND outcome between infants born before and after the introduction of DM. This may have been due to the similar percent of MOM at DOL 14 and 28 in the two eras. KEY POINTS · Donor milk use is increasing in VLBW infant. The impact of donor milk on neurodevelopment is unclear.. · Provision of mother's own milk was high at days of life 14 and 28 for both groups of infants.. · Donor milk was not associated with improved neurodevelopmental outcome..

Abstract
We performed a retrospective case-control cohort study following 146 preterm infants (≤32 weeks of gestation) who had been colonized with extended spectrum beta-lactamase producing Enterobacterales and compared them with 1:1 matched controls regarding rates of hospitalizations and outpatient visits because of infectious and gastrointestinal diseases and developmental impairment up to school age. Preterm infants with extended spectrum beta-lactamase producing Enterobacterales colonization did have neither higher rates of gastrointestinal or infectious diseases nor higher rates of developmental impairments up to the age of 6 years.

Abstract
OBJECTIVE To examine the effects of early echocardiography-targeted ibuprofen treatment of large patent ductus arteriosus (PDA) on survival without cerebral palsy at 24 months of corrected age. STUDY DESIGN We enrolled infants born at <28 weeks of gestation with a large PDA on echocardiography at 6-12 hours after birth to ibuprofen or placebo by 12 hours of age in a multicenter, double blind, randomized-controlled trial. Open-label ibuprofen was allowed for prespecified criteria of a hemodynamically significant PDA. The primary outcome was survival without cerebral palsy at 24 months of corrected age. RESULTS Among 337 enrolled infants, 109 had a small or closed ductus and constituted a reference group; 228 had a large PDA and were randomized. The primary outcome was assessed at 2 years in 108 of 114 (94.7%) and 102 of 114 (89.5%) patients allocated to ibuprofen or placebo, respectively. Survival without cerebral palsy occurred in 77 of 108 (71.3%) after ibuprofen, 73 of 102 (71.6%) after placebo (adjusted relative risk 0.98, 95% CI 0.83-1.16, P = .83), and 77 of 101 (76.2%) in reference group. Infants treated with ibuprofen had a lower incidence of PDA at day 3. Severe pulmonary hemorrhage during the first 3 days occurred in 2 of 114 (1.8%) infants treated with ibuprofen and 9 of 114 (7.9%) infants treated with placebo (adjusted relative risk 0.22, 95% CI 0.05-1.00, P = .05). Open-label rescue treatment with ibuprofen occurred in 62.3% of infants treated with placebo and 17.5% of infants treated with ibuprofen (P < .001), at a median (IQR) age of 4 (3, 5) and 4 (4, 12) days, respectively. CONCLUSIONS Early echocardiography-targeted ibuprofen treatment of a large PDA did not change the rate of survival without cerebral palsy.

Abstract
BACKGROUND Perinatally chikungunya infected neonates have been reported to have high rates of post-infection neurologic sequelae, mainly cognitive problems. In older children and adults chikungunya does not appear to have sequelae, but data on postnatally infected infants are lacking. METHODS We performed a prospective, non-controlled, observational study of infants infected before the age of 6 months with a severe chikungunya infection during the 2014-2015 epidemic in Curaçao, Dutch Antilles. Two years post-infection cognitive and motor - (BSID-III) and social emotional assessments (ITSEA) were performed. RESULTS Of twenty-two infected infants, two died and two were lost to follow up. Eighteen children were seen at follow-up and included in the current study. Of these, 13 (72%) had abnormal scores on the BSID-III (cognitive/motor) or ITSEA. CONCLUSION In the first study aimed at postnatally infected infants, using an uncontrolled design, we observed a very high percentage of developmental problems. Further studies are needed to assess causality, however until these data are available preventive measure during outbreaks should also include young infants. Those that have been infected in early infancy should receive follow up.

Abstract
OBJECTIVE The objective of this study is to examine the relationship between neonatal risk factors and feeding difficulties (FDs) in the NICU and the impact of FD on neurodevelopmental (ND) outcome in ELGA infants. STUDY DESIGN Two hundred and eighteen ELGA infants (59 FDs and 159 no-FDs) were compared for neonatal morbidities, feeding milestones, and Bayley-III scores at 8 and 20 mo CA. Multiple regression analyses adjusted for the effect of risk factors on FD and ND outcome. RESULTS Twenty-seven percent of infants had FD. Postmenstrual age (PMA) at start of oral feeds was the only predictor of FD. At 8 mo CA, FD was the strongest predictor of cognitive <85 (p = 0.018) and motor index <70 (p = 0.019). In linear regression, PMA at start of oral feeds was the only predictor of 8 mo cognitive and motor index (p = 0.006). FD did not predict ND outcome at 20 months CA. CONCLUSIONS FDs are common in ELGA infants and are associated with worse cognitive and motor outcomes in the first year of life.

Abstract
BACKGROUND Bronchopulmonary dysplasia (BPD) is the most frequent chronic lung disease in infancy and is associated with neonatal comorbidity and impairment in pulmonary and neurodevelopmental (ND) long-term outcome. METHODS This was a retrospective, single-center, cohort study to compare a cohort of very preterm infants (gestational age [GA], 24+0 -28+6 weeks) with BPD (n = 44), with a cohort of GA-matched preterm infants without BPD (n = 44) with regard to neonatal morbidity, incidence of lower respiratory tract infection (LRTI), ND outcome and growth to 2 years' corrected age (CA) and preschool age. RESULTS Bronchopulmonary dysplasia (incidence, 11.3%) was associated with a higher rate of neonatal pneumonia (26% vs 7%, P = 0.001), longer total duration of mechanical ventilation (mean days, 21 vs 13, P < 0.001), and a higher rate of pulmonary hypertension (20.5% vs 0%, P = 0.002) and of severe retinopathy of prematurity (13.6% vs 0%, P = 0.026). Incidence of LRTI was significantly higher in the BPD infants (50% vs 26%, P = 0.025). ND outcome did not differ between the two groups. Growth at neonatal intensive care unit discharge was similar. In the BPD cohort, rate of weight < 10th percentile was higher at 2 years' CA (52% vs 30%, P = 0.041) and rate of head circumference < 10th percentile was higher at preschool age (59% vs 27%, P = 0.028). CONCLUSION Neonatal respiratory morbidity was significantly higher in the BPD cohort, but long-term ND outcome did not differ. Infants with BPD had poorer growth.

Abstract
AIM The aim of this study was to identify and examine the psychometric properties of muscle tone assessments for children aged 0 to 12 years. METHOD Four electronic databases were searched to identify studies that included assessments of resting and/or active muscle tone. Methodological quality and overall psychometric evidence of studies were rated using the COnsensus-based Standards for the selection of health Measurement INstruments checklist. RESULTS Twenty-one assessments were identified from 97 included studies. All assessments were broad developmental assessments that included muscle tone items or subscales. Most assessments (16/21) were designed for young children (<2y). Four assessments measured resting and active tone and demonstrated at least moderate validity or reliability: the Amiel-Tison Neurological Assessment (ATNA) at term, Neonatal Intensive Care Unit Network Neurobehavioral Scale (NNNS), Premie-Neuro for newborn infants, and the Hammersmith Infant Neurological Examination (HINE) for infants aged 2 months to 2 years. For children over 2 years, the Neurological Sensory Motor Developmental Assessment (NSMDA) assesses resting and active tone but has limited validity. INTERPRETATION The ATNA at term, NNNS, Premie-Neuro, HINE, and NSMDA can assess resting and active tone in infants and/or children. Further psychometric research is required to extend reliability, validity, and responsiveness data, particularly for older children. WHAT THIS PAPER ADDS This is the first review of muscle tone assessments for children aged 0 to 12 years. Twenty-one assessments contain muscle tone items and 16 are for children under 2 years. Four assessments are reliable or valid to measure both resting and active tone.

Abstract
Background: ECMO therapy is worldwide declining in the neonatal population; hence, its therapeutic value is sometimes questioned. Objectives: To report our experience with neonatal ECMO due to respiratory failure over a 28 year time period. Methods: Retrospective single center observational study including all neonates admitted to ECMO due to respiratory failure between 1989 and 2016 at Graz, Austria. Data were collected regarding survival rate, duration of ECMO, complications, length of hospital stay, changes over time, and follow-up. Results: Sixty-seven neonates were admitted and 43 (64%) needed ECMO-median birth weight 3390 grams (range 1810-4150) and gestational age 39 weeks (32-43). Survival rate was 65% (28/43); with higher rates in meconium aspiration syndrome (MAS) 89% vs. congenital diaphragmatic hernia (CDH) 46% and septic shock 44% (p = 0.005 and p = 0.006, respectively). ECMO duration was median 5 days (1-30) and veno-arterial ECMO (52%) dominated. Need for ECMO therapy decreased over time (p < 0.001). Complications occurred in 31 (72%) neonates. Five neonates had cerebral hemorrhages (11.4%) and four had cerebral infarction (9.1%). Of 26 survivors 17 (65%) showed normal neurodevelopmental outcome at median follow-up of 73 months. Motor deficits were present in one case, cognitive deficits in 9 (35%). Median length of hospital stay was 78 days in those with deficits and 29 in those with normal neurodevelopmental outcome (p < 0.001). Conclusions: Survival rate did not change over the study time but indications for ECMO did. Cognitive impairment was the major long-term deficit following neonatal ECMO being associated with longer hospital stay.

Abstract
Background Considering the uncertainty of safety of anti-malarial drugs in pregnancy, efficacy studies are one of the few sources of clinical safety data. Complete safety evaluation is not usually incorporated in efficacy studies due to financial and human resource constraints. This review reports the methods used for the assessment of safety of artemisinin-based and quinine-based treatments in efficacy studies in pregnancy. Methods Methodology of assessment and reporting of safety in efficacy studies of artemisinin-based and quinine-based treatment in pregnancy was reviewed using seven databases and two clinical trial registries. The protocol was registered to PROSPERO (CRD42017054808). Results Of 48 eligible efficacy studies the method of estimation of gestational age was reported in only 32 studies (67%, 32/48) and ultrasound was used in 18 studies (38%, 18/48). Seventeen studies (35%, 17/48) reported parity, 9 (19%, 9/48) reported gravidity and 13 (27%, 13/48) reported both. Thirty-eight studies (79%, 38/48) followed participants through to pregnancy outcome. Fetal loss was assessed in 34 studies (89%, 34/38), but the definition of miscarriage and stillbirth were defined only in 11 (32%, 11/34) and 7 (21%, 7/34) studies, respectively. Preterm birth was assessed in 26 studies (68%, 26/38) but was defined in 16 studies (62%, 16/26). Newborn weight was assessed in 30 studies (79%, 30/38) and length in 10 studies (26%, 10/38). Assessment of birth weight took gestational age into account in four studies (13%, 4/30). Congenital abnormalities were reported in 32 studies (84%, 32/38). Other common risk factors for adverse pregnancy outcomes were not well-reported. Conclusion Incomplete reporting and varied methodological assessment of pregnancy outcomes in anti-malarial drug efficacy studies limits comparison across studies. A standard list of minimal necessary parameters to assess and report the safety component of efficacy studies of anti-malarials in pregnancy is proposed.

Abstract
BACKGROUND The association between human milk (HM) feeding in the NICU and neurodevelopmental (ND) outcome in very low birth weight (VLBW) infants is unclear. Limitations of previous studies include a lack of exact estimates of HM dose and of generalizability to minority populations. OBJECTIVE To determine the impact on ND outcome of an exact dose of HM received in the NICU in a diverse, contemporary cohort of VLBW infants. METHODS We included 430 VLBW infants born in the period 2008-2012 for whom the mean daily dose (DD) of HM received during the stay in the NICU (NICU HM-DD) was calculated prospectively from the daily nutritional intake from admission to discharge. Outcomes included Bayley-III index scores at 20 months' corrected age (CA) as assessed upon ND follow-up, which were collected retrospectively. Multivariable linear regression analyses controlled for neonatal and social risk factors. RESULTS Each 10 mL/kg/day increase in NICU HM-DD was associated with a 0.35 increase in cognitive index score (95% CI [0.03-0.66], p = 0.03), but no significant associations were detected for the language or motor indices. CONCLUSIONS There is a significant dose-dependent association between NICU HM intake and cognitive scores at 20 months' CA. Further follow-up will determine whether these findings persist at school age, and could help alleviate the special-education and health-care burden in this population.

Abstract
Objective To evaluate the relative impact of maternal education level (MEL) on cognitive, language, and motor outcomes at 20 months' corrected age (CA) in preterm infants. Study Design A total of 177 preterm infants born between 2008 and 2010 were tested at 20 months' CA using the Bayley Scales of Infant and Toddler Development-III. Multiple regression analyses were done to determine the relative impact of MEL on cognitive, language, and motor scores. Results Infants born to mothers with high school MEL were 3.74 times more likely to have a subnormal motor index, while those born to mothers with some college and graduate school MEL had reduced odds (0.36 and 0.12, respectively) of having subnormal language index at 20 months. In linear regression, MEL was the strongest predictor of cognitive, language, and motor scores, and graduate school MEL was associated with increases in cognitive, motor, and language scores of 8.49, 8.23, and 15.74 points, respectively. Conclusions MEL is the most significant predictor of cognitive, language, and motor outcome at 20 months' CA in preterm infants. Further research is needed to evaluate if targeted interventions that focus on early childhood learning and parenting practices can ameliorate the impact of low MEL.

Abstract
OBJECTIVE Early Intervention (EI) services promote development for preterm infants. In the state of Illinois, Child and Family Connections (CFC) is the intake agency that determines qualification for EI services. In Illinois, all extremely low birth weight (ELBW) infants are eligible for and referred to CFC at discharge from the Neonatal Intensive Care Unit (NICU). This study investigated: (1) patterns of CFC and EI enrollment, and; (2) predictors of CFC enrollment, need for CFC referral, and high EI therapy use among preterm infants seen in a NICU follow-up clinic. METHODS 405 preterm infants, including 169 ELBW infants, were seen in a NICU follow-up clinic at 4-, 8- and 20-months corrected age. CFC/EI data were collected at each visit. Multiple regression analyses adjusted for the effect of medical, sociodemographic and neurodevelopmental risk factors on CFC/EI outcome. RESULTS Despite the high rate of EI utilization and routine care by primary pediatricians, up to 28% of ELBW infants required a CFC referral from a NICU follow-up clinic. Medical and neurodevelopmental risk factors were associated with CFC enrollment while medical, sociodemographic and neurodevelopmental risk factors were associated with need for CFC referral. CONCLUSION NICU follow-up clinics facilitate appropriate CFC/EI services for preterm infants.

Abstract
AIM There is a large literature reporting risk factor analyses for poor neurodevelopment in children born very preterm (VPT: ≤32wks) or very low birthweight (VLBW: ≤1250g), which to date has not been formally summarized. The aim of this paper was to identify prognostic factors for cerebral palsy (CP) and motor impairment in children born VPT/VLBW. METHOD A systematic review was conducted using Medline, Embase, and Pyscinfo databases to identify studies published between 1 January 1990 and 1 June 2014 reporting multivariable prediction models for poor neurodevelopment in VPT/VLBW children (registration number CRD42014006943). Twenty-eight studies for motor outcomes were identified. RESULTS There was strong evidence that intraventricular haemorrhage and periventricular leukomalacia, and some evidence that the use of postnatal steroids and non-use of antenatal steroids, were prognostic factors for CP. Male sex and gestational age were of limited use as prognostic factors for CP in cohorts restricted to ≤32 weeks gestation; however, in children older than 5 years with no major disability, there was evidence that male sex was a predictive factor for motor impairment. INTERPRETATION This review has identified factors which may be of prognostic value for CP and motor impairment in VPT/VLBW children and will help to form the basis of future prognostic research.

Abstract
BACKGROUND Rates of neurological impairment among extremely low birth weight children (ELBW [<1 kg]) have decreased since 2000; however, their functioning is unexamined. OBJECTIVE To compare motor and cognitive functioning of ELBW children with neurological impairment, including cerebral palsy and severe hypotonia/hypertonia, between two periods: 1990 to 1999 (n=83) and 2000 to 2005 (n=34). METHODS Measures of function at 20 months corrected age included the Mental and Psychomotor Developmental Indexes of the Bayley Scales of Infant Development and the Gross Motor Functional Classification System as primary outcomes and individual motor function items as secondary outcomes. RESULTS Analysis failed to reveal significant differences for the primary outcomes, although during 2000 to 2005, sitting significantly improved in children with neurological impairment (P=0.003). CONCLUSION Decreases in rates of neurological impairment among ELBW children have been accompanied by a suggestion of improved motor function, although cognitive function has not changed.

Abstract
OBJECTIVE Postnatal steroids are used in neonatal intensive care units despite known side effects. Hydrocortisone (HC) use persists as it is believed to have less deleterious effects on neurodevelopmental (ND) outcome compared to other steroids. The literature is sparse with respect to the ND impact of HC use in recent years. Hence, we sought to examine the effect of HC use on ND outcome in a contemporary cohort of extremely low birth weight (ELBW) infants. STUDY DESIGN A total of 175 ELBW infants (86 HC exposed, 89 steroid naive) born in 2008 to 2010 were compared for mortality, morbidity and ND outcome at 8 and 20 months corrected age. Outcome measures included neurologic exam and results of the Bayley Scales of Infant and Toddler Development-III (BSITD-III). Multiple regression analyses adjusted for the effect of other risk factors on outcome. RESULT Overall, 65 (75%) of the HC and 74 (83%) of the no-HC groups survived to discharge. HC infants were smaller (mean birth weight (BW) 719 ± 127 g vs 837 ± 99 g) and of lower gestational age (GA) (mean GA 26.0 ± 1.7 weeks vs 27.5 ± 1.8 weeks) compared to the no-HC group. Patients in the HC group were more likely to be a multiple, have a severely abnormal head ultrasound, bronchopulmonary dysplasia, retinopathy of prematurity, necrotizing enterocolitis and receive treatment for patent ductus arteriosus and hypotension than those in the no-HC group. Of the HC group, the mean age at treatment was 20 ± 19 days, mean duration of treatment 49 ± 37 days. At 8 months, the HC group had lower mean motor (87 ± 18 vs 95 ± 15, P = 0.028) and fine motor (9 ± 2.9 vs 10.5 ± 2.6, P = 0.005) and higher rate of subnormal motor (44 vs 15%, P = 0.002) and fine motor scores (24 vs 6.5%, P = 0.017). In regression analyses, HC exposure >7 days was significantly related to worse outcome on fine motor scores at 8 months while cumulative days of HC exposure was a predictor of worse outcome on language at 8 months and motor outcome at 20 months. Each additional day of HC exposure increased the odds of subnormal receptive and expressive language in the first year of life by 4 and 2%, respectively, and increased odds of subnormal motor function by 2% in the 2nd year of life. CONCLUSION HC exposure for >7 days is associated with worse performance in fine motor skills in the first year of life, while cumulative HC exposure negatively impacts receptive and expressive language skills in the first year and motor skills in the second year of life after adjusting for neonatal and social risk factors.

Abstract
OBJECTIVE To examine the association between cardiorespiratory events (CRE) and neurodevelopmental (ND) outcome at 8 and 20 months corrected age (CA) in a contemporary extremely low birth weight (ELBW )cohort. STUDY DESIGN Retrospective chart review of 98 ELBW infants born in 2009 to 2010 who completed ND assessments at 8 and 20 months CA. Neonatal, sociodemographic, CRE and ND data were collected. ND outcome measures included neurologic examination and results from the Bayley Scales of Infant and Toddler Development-III. Multiple regression analyses adjusted for the impact of neonatal risk factors on ND outcome. RESULT After adjusting for neonatal and social variables, greater frequency of CRE was related to worse language scores at 8 months, while CRE of greater severity were related to worse language at 20 months CA. CONCLUSION CRE in ELBW infants have impact on language development in the first two years of life.

Abstract
OBJECTIVE To study the impact of neonatal sepsis on the long-term neurodevelopmental outcome in very low birth weight (VLBW) infants. STUDY DESIGN Systematic review and meta-analysis of observational studies comparing neurodevelopmental outcomes in VLBW infants exposed to culture-proven sepsis in the neonatal period with similar infants without sepsis. RESULT Seventeen studies involving 15,331 infants were included in the meta-analysis. Sepsis in VLBW infants was associated with an increased risk of one or more long-term neurodevelopmental impairments (odds ratio (OR) 2.09; 95% confidence interval (CI) 1.65 to 2.65) including cerebral palsy (CP; OR 2.09; 95% CI 1.78 to 2.45). Heterogeneity (I(2)=36.9%; P=0.06) between the studies was significant and related to variations in patient characteristics, causative pathogens and follow-up methods. Sensitivity analyses based on study design, follow-up rate and year of birth were not significantly different from the overall analysis. CONCLUSION The meta-analysis suggests that sepsis in VLBW infants is associated with a worse neurodevelopmental outcome including higher incidence of CP.

Abstract
BACKGROUND Longitudinal motor assessment in infants at different neurodevelopmental risk has not been previously evaluated using structured assessments. AIM To verify if the Hammersmith Infant Neurological Examination (HINE) is a good tool to predict the neuromotor outcome in infants discharged from a level II-III Neonatal Intensive Care Unit (NICU) METHODS: In this cohort analysis, 1541 infants discharged from our NICU between January of 2002 and the April 2006 were enrolled and assessed using the HINE at 3, 6, 9, 12 months. At two years, these infants were further assessed, and grouped into infants with normal outcome (1150), with mild disability (321) and with cerebral palsy (70), RESULTS Correlation analysis of Spearman showed a significant (p < 0.0001) and moderate (r(2) = -0.55 to -0.73) negative correlation between HINE scores (3, 6, 9, 12 months) and neurological outcome at two years. Cut-off scores for each assessment' age were provided as predictive value for cerebral palsy. DISCUSSION This study mainly showed that HINE, as soon as the first months of life, helps in the process of prediction of neurological outcome at two years of age in a heterogeneous population of infants discharged from an NICU.

Abstract
BACKGROUND An increased risk of cerebral palsy in multiples has been reported. AIMS To determine the risk for the development of periventricular leukomalacia (PVL) of twin and triplet pregnancy. STUDY DESIGN Retrospective single-centre study at a tertiary care university hospital. SUBJECTS Infants ≤ 35 weeks gestational age born between 1988 and 2008. OUTCOME MEASURES Risk of twin and triplet compared to singleton pregnancy regarding development of PVL in one offspring. RESULTS Of 6195 infants 117 singletons and 39 multiples were diagnosed as having cystic PVL. Perinatal data did not differ as did not ultrasonographic findings and neurologic outcome. The relative risk (RR) of a twin pregnancy resulting in at least one infant with PVL when born prior to 36 weeks was 2.181 (CI 95% 1.474-3.228, p < .0001), and 6.793 (CI 95% 2.470-13.108, p < .0001) of a triplet pregnancy. In-vitro fertilisation was present in 3% of affected twins compared to 100% in triplets (p < .001). CONCLUSION We found an increased risk for PVL in preterm twin and triplet pregnancies.

Abstract
OBJECTIVE To determine outcomes at age 3 years in babies born before 27 completed weeks' gestation in 2006, and to evaluate changes in outcome since 1995 for babies born between 22 and 25 weeks' gestation. DESIGN Prospective national cohort studies, EPICure and EPICure 2. SETTING Hospital and home based evaluations, England. PARTICIPANTS 1031 surviving babies born in 2006 before 27 completed weeks' gestation. Outcomes for 584 babies born at 22-25 weeks' gestation were compared with those of 260 surviving babies of the same gestational age born in 1995. MAIN OUTCOME MEASURES Survival to age 3 years, impairment (2008 consensus definitions), and developmental scores. Multiple imputation was used to account for the high proportion of missing data in the 2006 cohort. RESULTS Of the 576 babies evaluated after birth in 2006, 13.4% (n=77) were categorised as having severe impairment and 11.8% (n=68) moderate impairment. The prevalence of neurodevelopmental impairment was significantly associated with length of gestation, with greater impairment as gestational age decreased: 45% at 22-23 weeks, 30% at 24 weeks, 25% at 25 weeks, and 20% at 26 weeks (P<0.001). Cerebral palsy was present in 83 (14%) survivors. Mean developmental quotients were lower than those of the general population (normal values 100 (SD 15)) and showed a direct relation with gestational age: 80 (SD 21) at 22-23 weeks, 87 (19) at 24 weeks, 88 (19) at 25 weeks, and 91 (18) at 26 weeks. These results did not differ significantly after imputation. Comparing imputed outcomes between the 2006 and 1995 cohorts, the proportion of survivors born between 22 and 25 weeks' gestation with severe disability, using 1995 definitions, was 18% (95% confidence interval 14% to 24%) in 1995 and 19% (14% to 23%) in 2006. Fewer survivors had shunted hydrocephalus or seizures. Survival of babies admitted for neonatal care increased from 39% (35% to 43%) in 1995 to 52% (49% to 55%) in 2006, an increase of 13% (8% to 18%), and survival without disability increased from 23% (20% to 26%) in 1995 to 34% (31% to 37%) in 2006, an increase of 11% (6% to 16%). CONCLUSION Survival and impairment in early childhood are both closely related to gestational age for babies born at less than 27 weeks' gestation. Using multiple imputation to account for the high proportion of missing values, a higher proportion of babies admitted for neonatal care now survive without disability, particularly those born at gestational ages 24 and 25 weeks.

Abstract
AIM The aim of this article was to evaluate the Revised Clinical Risk Index for Babies' (CRIB-II) severity of illness score as a predictor of moderate to severe functional disability (FD) in very premature infants. METHODS Population study of infants born <29 weeks' gestation cared for in all Neonatal Intensive Care Unit in New South Wales and the Australian Capital Territory between 1998 and 2003. FD at 2-3 years corrected age was defined as developmental delay (quotient < 2 standard deviation), non-ambulatory cerebral palsy (needing aids to walk), blindness (acuity <6/60 in better eye) or deafness (hearing aids). Sensitivity and specificity of CRIB-II scores to predict FD were performed by receiver operating characteristic curve analysis. RESULTS Of study population of 2210, 480 (21.7%) died before hospital discharge. Among 1328 infants assessed, 217 (16.3%) had FD, 109 (8.2%) developmental delay, 75 (5.6%) cerebral palsy and 54 (4.1%) blindness or deafness. CRIB-II performed significantly better than gestation or birthweight (BW) alone in predicting mortality (area under the curve (AUC) ± standard error 0.83 ± 0.01, vs. 0.78 ± 0.01 and 0.76 ± 0.01, respectively). CRIB-II scores were significantly higher in FD than non-FD children (11.9 ± 2.9 vs. 10.1 ± 2.6), but the AUC for CRIB-II (0.68 ± 0.02) did not significantly differ from that of gestation (0.65 ± 0.02) and BW (0.65 ± 0.02). CONCLUSION CRIB-II improved prediction of mortality but did not perform better than gestational age or BW in predicting FD. We would caution clinicians against using the infant's condition at admission to predict long-term outcome.

Abstract
OBJECTIVE We sought to determine the incidence of necrotizing enterocolitis (NEC) and spontaneous intestinal perforation (SIP) in surviving extremely low-birth-weight (ELBW, <1000 g birth weight) infants and to establish the impact of NEC on outcomes by hospital discharge and at 18 to 22 months adjusted age in a large, contemporary, population-based practice. STUDY DESIGN Hospital outcome data for all ELBW infants born in the greater Cincinnati region from 1998 to 2009 were extracted from the National Institute of Child Health Neonatal Research Network Database. Neurodevelopmental outcome at 18 to 22 months was assessed using Bayley Scales of Infant Development-II scores for Mental Developmental Index and Psychomotor Developmental Index. Multivariable logistic regression was used and adjusted odds ratios reported to control for confounders. RESULT From 1998 to 2009, ELBW infants accounted for 0.5% of the 352 176 live-born infants in greater Cincinnati. The incidence of NEC was 12%, with a 50% case-fatality rate. Death before discharge, morbid complications of prematurity and neurodevelopmental impairment were all increased among infants diagnosed with NEC. Infants with surgical NEC and SIP had a higher incidence of death, but long-term neurodevelopmental outcomes were not different comparing surviving ELBW infants with medical NEC, surgical NEC and SIP. CONCLUSION Although ELBW infants comprise a very small proportion of live-born infants, those who develop NEC and SIP are at an increased risk for death, morbid complications of prematurity and neurodevelopmental impairment. No significant differences in neurodevelopmental outcomes were observed between the medical and surgical NEC and SIP groups.

Abstract
BACKGROUND/OBJECTIVE Hyperglycaemia is common in very premature neonates and is associated with increased risk of intraventricular haemorrhage, necrotising enterocolitis, sepsis and death. Administration of insulin may risk hypoglycaemia and associated complications. To determine effects of insulin infusions in very premature infants on morbidity, mortality and long-term neurodevelopmental outcome. METHODS Retrospective audit of 97 infants delivered at <29 weeks gestation and admitted to The Canberra Hospital NICU. Data on insulin treatment, Blood Glucose Levels (BGL's) prior and during insulin therapy, episodes of significant hypoglycaemia and neurodevelopmental outcome at 12 months corrected age was collected. RESULTS 17 (17.5%) neonates received insulin. Episodes of hypoglycaemia were infrequent (1.3%, 95% CI 0.5-2.9). Multiple regression analysis showed that insulin treatment was not associated with an increased risk of retinopathy of prematurity (OR 3.6, 95% CI 0.4-32.3) or mortality (OR 1.2, 95% CI 0.29-5.0). No significant difference in 12 month neurodevelopmental or anthropometric outcomes was detected in infants who received insulin. CONCLUSION Insulin infusions for hyperglycaemia appear to be safe with infrequent episodes of hypoglycaemia, no increased risk of morbidity or mortality and no adverse effect on long-term neurodevelopmental outcome.

Abstract
OBJECTIVES To determine whether male gender has an effect on survival, early neonatal morbidity, and long-term outcome in neonates born extremely prematurely. METHODS Retrospective review of the New South Wales and Australian Capital Territory Neonatal Intensive Care Unit Data Collection of all infants admitted to New South Wales and Australian Capital Territory neonatal intensive care units between January 1998 and December 2004. The primary outcome was hospital mortality and functional impairment at 2 to 3 years follow-up. RESULTS Included in the study were 2549 neonates; 54.7% were male. Risks of grade III/IV intraventricular hemorrhage, sepsis, and major surgery were found to be increased in male neonates. Hospital mortality (odds ratio 1.285, 95% confidence interval 1.035-1.595) and moderate to severe functional disability at 2 to 3 years of age (odds ratio 1.877, 95% confidence interval 1.398-2.521) were more likely in male infants. Gender differences for mortality and long-term neurologic outcome loses significance at 27 weeks gestation. CONCLUSIONS In the modern era of neonatal management, male infants still have higher mortality and poorer long-term neurologic outcome. Gender differences for mortality and long-term neurologic outcome appear to lose significance at 27 weeks gestation.

Abstract
BACKGROUND Septic episodes in preterm infants recently have been reported to be associated with periventricular leukomalacia (PVL). The role of hypocarbia as an independent risk factor for PVL in clinical studies raises many questions without conclusive answers. AIMS To evaluate risk factors for cystic PVL focussing on the influence of hypocarbia. STUDY DESIGN Retrospective single centre case-control study. SUBJECTS Preterm infants 24 to 35 weeks of gestational age and matched (1:2 for gender, birth year, gestational age and birth weight) controls. OUTCOME MEASURES Multivariate analysis of perinatal factors being associated with cystic PVL diagnosed by serial ultrasound examinations. RESULTS Univariate analysis of risk factors revealed lower 5 and 10 min Apgar scores, and higher rates of neonatal seizures, early-onset sepsis, neonatal steroids, respiratory distress syndrome with surfactant replacement therapy, and episodes of hypocarbia significantly being associated with PVL. Multivariate analysis using a logistic regression model revealed early-onset sepsis and hypocarbia being significantly associated with PVL (p=.022 and .024, respectively). Lowest PaCO(2) values did not differ as did not the duration of hypocarbia, but the onset of hypocarbia was significantly later in PVL cases compared to controls (mean 26 vs. 15 h, p=.033). Neurodevelopmental follow-up at a median time of 46 months was poor showing 88% of the cases having an adverse neurological outcome. CONCLUSION We found early-onset sepsis and episodes of hypocarbia within the first days of life being independently associated with PVL.

Abstract
OBJECTIVE To determine the growth and neurosensory outcomes of infants with birth weight ≤ 1,500 g or gestation ≤ 32 wks at 18 months corrected age. This prospective cohort study was conducted at a Level III neonatal unit in India. The neonates with birth weight ≤ 1,500 g or gestation ≤ 32 wks were included in the study. METHODS The infants were followed up at 3,6,9,12 and 18 months corrected age. Weight, length and head circumference were plotted on WHO multisite growth reference study (MGRS) charts. Neurological examination was conducted by Amiel-Tison method, hearing was evaluated with brainstem auditory evoked responses, vision assessed with Teller acuity cards, and development assessed with Developmental Assessment Scales for Indian Infants II. RESULTS During the period from July 2006 through June 2007, there were 141 neonates born at gestation ≤ 32 wks or birth weight ≤ 1,500 g. Seven infants had major malformations, 30 died before discharge, 36 had residence > 20 km and parents of four had refused consent. The remaining 64 neonates were enrolled for follow up. The mean gestation and birth weight were 31(2.4) wks and 1208 (365) g respectively. There were 38 (59%) small for gestation infants. Fifty-five infants completed 18 months follow up for growth outcomes. Seventeen (30.9%; 95% CI 18.3% to 43.5%) infants were undernourished, 28(50.9%; 95% CI 37.3% to 64.6%) were stunted, 8(14.5%; 95% CI 0 to 24) were wasted and 14(25.4%; 95% CI 13.6% to 37.3%) had microcephaly. Infants with birth weight <1,000 g (n = 17) were significantly more affected. Ten (58.8%; p < 0.01) were undernourished, 13(76.5%; p < 0.01) were stunted and 10(58.8%; p < 0.01) had microcephaly. Complete formal neurological evaluation for development, hearing and vision was done in 31 infants. Six of these 31 (19.3%; 95% CI 4.6% to 34.1%) infants had one or more major disabilities. These included cerebral palsy (n = 3), developmental delay (development quotient <70, n = 3), and deafness (n = 3). CONCLUSIONS Very low birth weight infants are at a high risk of neurosensory disability and growth failure. There is a need to create a nation-wide database of these infants for neurodevelopment and growth outcomes.

Abstract
AIMS The purpose of this study was to determine whether head circumference (HC) catch-up is associated with improved neurocognitive development. DESIGN A retrospective cohort study was conducted in 179 preterm very low birth weight (VLBW) (BW≤1500 g) infants. The infants were born in 2000-2002 and were followed to the age of 5.5 years. The association between HC catch-up and neurodevelopmental outcome was assessed and perinatal risk factors, infant characteristics and nutritional practices associated with HC catch-up were determined. RESULTS HC catch-up occurred in 59 (34%) infants and was positively correlated with neurodevelopmental outcome. The likelihood of HC catch-up increased with increasing birth weight and gestational age. HC catch-up occurred more often with breast milk feeding during hospitalization and with supplemental formula feeding at discharge, but decreased in prevalence with longer duration of breastfeeding after discharge. HC catch-up was more likely to occur in first-born infants and in families with high socioeconomic status. Most HC catch-up occurred between birth and three months corrected age. CONCLUSION Among preterm-VLBW infants, there is a close relation between HC growth and neurodevelopmental outcome. Efforts to improve neurocognitive outcomes should focus on factors associated with HC catch-up.

Abstract
OBJECTIVE Our objective was to examine the outcome of term infants who developed moderate non-haemolytic jaundice as information regarding the neurodevelopmental outcome of term infants with moderately severe non-haemolytic hyperbilirubinemia remains controversial. STUDY DESIGN Thirty-nine term infants rehospitalised with non-haemolytic hyperbilirubinemia (serum bilirubin levels: 20-30 mg/dL) during the first 2 weeks of life (study group), were assessed and compared to 36 children born at term who did not develop neonatal jaundice (control group). Assessment consisted of the Bailey 2 test, speech evaluation, behavioural hearing test and a neurological examination. RESULTS The subjects were assessed at a mean age of 3 years. There was no difference between the groups with regard to background data, except for the mean gestational age (38 + 1.3 weeks (study group) vs. 39.5 + 1.4 weeks (control group), P= 0.01). There were no significant differences between the groups in outcome parameters initially, and after correcting for possible confounding factors. None of the children in either of the groups had a neurosensory hearing deficit or any significant neurological deficiency. There was no correlation of outcome parameters with the admission serum Bilirubin levels or with the duration of hyperbilirubinemia. CONCLUSION No untoward outcome was found in term healthy infants with moderately severe non-haemolytic hyperbilirubinemia. Moreover, we did not find a correlation of outcome with serum bilirubin levels or with the duration of the hyperbilirubinemia in the study group.

Abstract
Bilateral loss of cortical somatosensory evoked potential (SEP) is considered the single best indicator of adverse outcome in acute encephalopathy of adult patients and older children. This study determines whether the presence or absence of the neonatal cortical SEP can predict cerebral palsy at two years in survivors of neonatal encephalopathy scored according to Sarnat criteria. We also compare SEPs with visual evoked potentials (VEPs), the EEG and neonatal neurological status. Fifty-nine neonates admitted to the neonatal intensive care unit had SEP, VEP and EEG recordings analysed according to the presence (n=37, 63%) or absence (n=22, 37%) of neonatal encephalopathy (score >or=1). Cortical SEP was always present in the perinatal period in those surviving without major neurological disability, while it was bilaterally absent in all but one patient with a subsequent diagnosis of cerebral palsy. Multivariate analysis using the logistic regression model showed that bilateral loss of cortical SEP and Sarnat Score correctly classified the neurological outcome in all patients. Bilateral absence of cortical SEP indicates early identification of neonates at risk of cerebral palsy indicating that EPs have a clinical role in the workup of neonatal encephalopathy.

Abstract
OBJECTIVE To determine whether changes in neonatal practice and morbidity since 2000 have improved the growth attainment of infants with bronchopulmonary dysplasia (BPD). STUDY DESIGN We compared the respective z-scores of the weight, length and head circumference of extremely low-gestational-age infants (aged <28 weeks) with BPD at birth, 40 weeks and 20 months corrected age (CA) during two time periods, namely period I, 1996-1999 (n=117) and period II, 2000-2003 (n=105), and examined the effects of significant changes in neonatal practice, morbidities and neurosensory outcome on 20-month growth outcomes. RESULT During the most recent period (2000-2003), there was a significant increase in mean weight z-scores (-1.60 vs -1.22) and decrease in rates of subnormal weight (40 vs 21%), P<0.05 at 20 months CA but not in those of length or head circumference. Significant predictors of the 20-month weight z-score included time period (period I vs II), duration of ventilator dependence and 20-month neurosensory abnormality (all P<0.05). CONCLUSION Despite an improvement in weight since 2000, poor growth attainment remains a major problem among infants with BPD.

Abstract
The efficacy of artemether and artemether followed by mefloquine was evaluated in 45 pregnant women with drug resistant Plasmodium falciparum malaria during the second and third trimesters. There was prompt clinical response to both treatment regimens. The parasite and fever clearance times and the cure rate were similar in both groups. Except for the correlation between initial parasite density and fever clearance time in the artemether-mefloquine group, there was no correlation between initial parasite density and parasite or fever clearance times in the two groups. Similarly, there was no correlation between parasite and fever clearance. Both treatment regimens were well tolerated. All newborn babies of the participating women were normal at birth. Physical and neurodevelopmental assessment of the newborn babies followed up for a period varying between 6 and 36 months were within normal limits. Artemether alone or with mefloquine are effective and do not produce undue deleterious effects in pregnant patients with drug-resistant falciparum malaria during the second and third trimesters.

Abstract
BACKGROUND Extremely low birth weight (< or =1000 g) children have increased rates of cerebral palsy and other abnormal neurologic findings. OBJECTIVE To investigate the stability of neuromotor findings between 18 and 30 months' adjusted age in extremely low birth weight infants. METHODS. Seven hundred nineteen extremely low birth weight infants with assessments at 18 and 30 months' adjusted age were included in this analysis. At each visit a neurologic examination, the modified gross motor function classification system, and the Bayley Scales of Infant Development II were administered. Logistic regression models were constructed to assess neonatal factors and neuromotor function at 18 months of age associated with stability in neuromotor function. RESULTS Eighty-four percent of the children had agreement in neurologic/motor function at both visits. However, classification changed from normal to abnormal in 6% and from abnormal to normal in 10%. Diagnosis of cerebral palsy was consistent for 91% of the children, and the gross motor function classification system score was consistent for 83%. In multivariate models, factors associated with decreased severity or absence of cerebral palsy diagnosis at 30 months of age were higher gestational age, no periventricular leukomalacia or severe intraventricular hemorrhage, and a gross motor function classification system score of 0 (normal) at the 18-month visit, whereas factors associated with a new cerebral palsy diagnosis at 30 months of age were postnatal steroid use, periventricular leukomalacia or severe intraventricular hemorrhage, a gross motor function classification system score of > or =1 at 18 months of age, and asymmetrical limb movement at 18 months of age. CONCLUSIONS Stability of neurologic diagnosis in 84% and cerebral palsy in 91% of the children is reassuring. However, for a significant percentage of children, the neurologic diagnosis changes between 18 and 30 months of age. The diagnosis of cerebral palsy may be delayed in some infants until an older adjusted age.

Impact of postnatal corticosteroid use on neurodevelopment at 18 to 22 months' adjusted age: effects of dose, timing, and risk of bronchopulmonary dysplasia in extremely low birth weight infants.

Abstract
OBJECTIVE Postnatal steroid use decreases lung inflammation but increases impairment. We hypothesized that increased dose is associated with increased neurodevelopmental impairment, lower postmenstrual age at exposure increases impairment, and risk of bronchopulmonary dysplasia modifies the effect of postnatal corticosteroid. METHODS Steroid dose and timing of exposure beyond 7 days was assessed among 2358 extremely low birth weight infants nested in a prospective trial, with 1667 (84%) survivors examined at 18 to 22 months' postmenstrual age. Logistic regression tested the relationship between impairment (Bayley Mental Developmental Index/Psychomotor Developmental Index of <70, disabling cerebral palsy, or sensory impairment), total dose (tertiles: <0.9, 0.9-1.9, and >/=1.9 mg/kg), and postmenstrual age at first dose. Separate logistic regression tested effect modification according to bronchopulmonary dysplasia severity (Romagnoli risk > 0.5 as high risk, n = 2336 (99%) for days of life 4-7). RESULTS Three hundred sixty-six (16%) neonates were steroid-treated (94% dexamethasone). Treated neonates were smaller and less mature; 72% of those treated were at high risk for bronchopulmonary dysplasia. Exposure was associated with neurodevelopmental impairment/death. Impairment increased with higher dose; 71% dead or impaired at highest dose tertile. Each 1 mg/kg dose was associated with a 2.0-point reduction on the Mental Developmental Index and a 40% risk increase for disabling cerebral palsy. Older age did not mitigate the harm. Treatment after 33 weeks' postmenstrual age was associated with greatest harm despite not receiving the highest dose. The relationship between steroid exposure and impairment was modified by the bronchopulmonary dysplasia risk, with those at highest risk experiencing less harm. CONCLUSIONS Higher steroid dose was associated with increased neurodevelopmental impairment. There is no "safe" window for steroid use in extremely low birth weight infants. Neonates with low bronchopulmonary dysplasia risk should not be exposed. A randomized trial of steroid use in infants at highest risk is warranted.

Abstract
OBJECTIVES The goals were to assess postdischarge growth and developmental progress of very low birth weight (birth weight: <1500 g) premature infants in a predominantly Hispanic population and to identify predictors for neurodevelopmental impairment at 3 years of age. METHODS A cohort of 135 very low birth weight infants (gestational age: 23 to 35 weeks) were monitored to 3 years of age. Maternal and neonatal characteristics, anthropometric z scores, and developmental performance (using corrected age until 24 months) were analyzed collectively and according to gestational age groups. Specific criteria for failure to thrive and microcephaly were used. RESULTS A characteristic pattern of poor weight gain in the first 12 months was followed by accelerated weight gain starting at 18 months, whereas head growth decreased at 18 months, with recovery beginning at 30 months of age. Infants born at gestational age of <or=26 weeks remained growth-impaired at 3 years of age, whereas infants born at gestational age of >or=27 weeks achieved catch-up growth by 30 months of age. Mean developmental scores also decreased in infancy, with improvements in motor development emerging at 18 months and cognitive skills at 30 months. Growth z scores, particularly for head growth, correlated with developmental scores. Infants born at gestational age of <or=26 weeks were most likely to have neonatal morbidities, failure to thrive, and neurodevelopmental impairment. With adjustment for gestational age and neonatal morbidities, Hispanic acculturation, failure to thrive, and microcephaly were predictive of neurodevelopmental impairment. CONCLUSIONS Very low birth weight infants exhibited growth patterns that coincided with developmental progress in the first 3 years of life. Birth at gestational age of <or=26 weeks was associated with greatest risk for developmental impairment, whereas failure to thrive and microcephaly increased neurodevelopmental impairment risk regardless of gestational age.

Abstract
The unfavorable impact of prematurity on the developing cerebellum was recently recognized, but the outcome after impaired cerebellar development as a prematurity-related complication is hitherto not adequately documented. Therefore we compared 31 preterm patients with disrupted cerebellar development to a control group of 31 gender and gestational age matched premature infants with normal cerebellar development. Supratentorial brain injuries during the neonatal period were comparable between the groups. At a minimum age of 24 months motor and mental development was assessed by standardized tests. Disrupted cerebellar development was associated with significantly poorer scores both in the subtests for neuromotor (p < 0.001) and mental development (p < 0.001), respectively. Mixed CP was diagnosed in 48% of affected patients, whereas none of the patients of the control group had mixed CP. Microcephaly and epilepsy were significantly related to disrupted cerebellar development. Preterm patients with disrupted cerebellar development exhibit poorer outcome results in all investigated variables. The role of the cerebellum in neurodevelopment after prematurity seems to be underestimated so far.

Abstract
AIM To assess the efficacy of a preterm-targeted screening programme against the routine Australian National Health Medical Research Council (NHMRC) universal child health screening programme to detect disability in a general practice setting in children born < or =31 weeks gestation at 12-months of age. METHODS Multi-centred trial involving 202 preterm children randomised to receive the preterm-targeted or NHMRC programme. Primary outcome, correct identification of neurosensory disability by general practitioners assessed against gold standard paediatric assessments. Sensitivity analysis estimated interrater agreement and screening accuracy. Secondary outcomes, post natal depression (PND), parental stress, health service use, screening programme helpfulness and correct identification of levels of disability severity. RESULTS Of the 195 infants with data on the primary outcome in the preterm-targeted group, their general practitioners correctly identified the disability status of 61/93 (65.6%) children, as compared with 69/102 (67.6%) in the NHMRC group (odds ratios (OR) 0.91 95% confidence interval (CI) 0.50, 1.65). Responses where general practitioners were unsure of a child's disability status were coded as incorrect and not paired for sensitivity analysis. Sensitivity analysis for 180 diagnostic pairs showed fair interrater agreement for both groups (preterm-targeted k = 0.30 vs. NHMRC k = 0.29) with screening test results favouring the preterm-targeted group with greater sensitivity (73% vs. 33%) but lower specificity (70% vs. 92%) resulting in more over referrals (30% vs. 8%); however, these had a significantly lower mean Developmental Quotient (DQ) score compared with non-disabled children. PND scores were higher in preterm-targeted group (OR 1.33 95% CI 0.01, 2.66). CONCLUSION The preterm-targeted programme used by general practitioners: (i) did not improve overall identification of disability status compared to the NHMRC universal programme (Australian New Zealand Clinical Trails Registry number, ACTRN 12606000472572); however (ii) it did demonstrate greater efficacy as a screening tool in accurately identifying disabled children.

Abstract
BACKGROUND The availability of a score for predicting neonatal outcome prior to discharge may help us to define the risk of developmental disorders in very low birth weight infants. AIM To compare Scheiner's Perinatal Risk Inventory (PERI) with Brazy's Neurobiological Risk Score (NBRS) when applied at discharge, in predicting developmental delay at 24 months of age. STUDY DESIGN To evaluate the predictive power of the two tests, we measured their sensitivity and specificity in predicting outcome (Mental Development Index, MDI, Psychomotor Development Index, PDI, and Amiel-Tison Neurological Examination) in an observational study. SUBJECTS 102 very low birth weight infants (BW <1,500 g) admitted to our NICU at the Pediatric Department of Padova University. RESULTS In the cohort studied, 75.5% of the patients had a normal MDI, while 24.5% showed a delayed performance (8.8% mildly and 15.7% severely so); the PDI was normal in 74.5% patients, whilst 25.5% had a delayed performance (9.8% mildly and 15.7% severely so). According to the Amiel-Tison test, neurological performance was normal in 66% patients, impaired without disability in 19% and impaired with disability in 15%. NBRS showed a sensitivity and specificity respectively of 0.96 and 0.23 (MDI), 0.96 and 0.24 (PDI), 0.94 and 0.25 (Amiel-Tison test); for PERI were 0.88 and 0.54 (MDI), 0.77 and 0.51 (PDI), 0.82 and 0.57 (Amiel-Tison test). The PERI and NBRS can predict the MDI with an AUC >0.8 and the PDI or Amiel-Tison findings with an AUC of 0.7-0.8. No significant differences were found between the areas under the ROC curves using the NBRS and the PERI. CONCLUSIONS : In assessing the prognosis for individual babies, the physician can choose either the PERI or the NBRS to predict PDI, MDI or Amiel-Tison performance.

Abstract
BACKGROUND Diagnostic tools of birth asphyxia provide only an uncertain prediction of neurological outcome. AIMS To assess whether TOI and DeltaCBV, combined with a set of biochemical and neurophysiological variables, have any diagnostic and prognostic value in birth depression or asphyxia. STUDY DESIGN Case control study at the nursery and NICU of the Padova University Children's Hospital. SUBJECTS 22 term neonates with an Apgar score < or = 6 at 5', a 1-h umbilical artery pH value < or = 7.25 with an increased base deficit and a gestational age > or = 36 weeks; 15 healthy term infants with an Apgar score > or = 9 at 5'. OUTCOME MEASURES Troponin I and NIRS measurements (TOI and DeltaCBV) were assessed in both groups. Blood gases, neurological evaluation, US, NIRS, EEG and SEP were evaluated in the infants with depression or asphyxia. RESULTS Troponin I was higher in the study group than in controls (p=0.04), showing a correlation with base excess values. In the depressed/asphyxiated neonates with an abnormal outcome at 1 year, TOI rose to 80.1% vs 66.4% in controls (p=0.04) and 74.7% in infants with a normal 1-year outcome. A multiple regression model showed a significant multiple correlation coefficient, R=0.79, p<0.001, where the predictive variables significantly associated with outcome were SEP and BE. CONCLUSIONS Troponin I is a useful short-term index of birth asphyxia or perinatal depression. An increased TOI suggests a risk of abnormal neurological outcome at 1 year. Among the cotside variables, BE and evoked potential abnormalities were the best predictors of abnormal outcome in this study.

Abstract
BACKGROUND Neurodevelopmental impairment of extremely low birth weight infants increased in the 1990s. Modern therapeutic changes may have influenced more recent neonatal outcomes. OBJECTIVE We sought to compare neonatal therapies and outcomes among all extremely low birth weight infants born in 2000-2002 (period III) to 2 previous periods: 1982-1989 (period I) and 1990-1999 (period II). METHODS The population included 496 extremely low birth weight infants born at our perinatal center during period I, 749 during period II, and 233 during period III. Therapies, rates of death, and survival with and without impairment at 20 months' corrected age were compared. RESULTS Between periods I and II, survival increased from 49% to 68% as did neonatal morbidity. This resulted in increased survival without impairment but also increased survival with impairment. Changes in therapy during period III included an increase in antenatal steroid use and a decrease in postnatal steroid use, although the rate of chronic lung disease did not change. Sepsis decreased, as did severe intraventricular hemorrhage. On follow-up, the rate of cerebral palsy decreased from 13% to 5%, resulting in a decrease in neurodevelopmental impairment from 35% to 23%. As a result, during period III versus II, survival without impairment increased, whereas survival with impairment decreased. CONCLUSION Since 2000, neurodevelopmental impairment has decreased among extremely low birth weight infants. A variety of perinatal and neonatal factors were associated with the improved outcomes including increased antenatal steroid use and cesarean section delivery, as well as decreased sepsis, severe cranial ultrasound abnormalities, and postnatal steroid use despite no change in the rate of chronic lung disease.

Abstract
OBJECTIVES The goals were to develop safe 4.7-T MRI examination protocols for newborn infants and to explore the advantages of this field strength in neonatal encephalopathy. METHODS Nine ventilated newborn infants with moderate or severe encephalopathy were studied at 4.7 T, with ethical approval and informed parental consent. The custom-made, 4.7-T-compatible, neonatal patient management system included acoustic noise protection and physiologic monitoring. An adult head coil was used. Acquisition parameters for T2-weighted fast spin echo MRI and a variety of T1-weighted methods were adapted for MRI of neonatal brain at 4.7 T. The pulse sequences used had a radiofrequency specific absorption rate of <2 W/kg. RESULTS Physiologic measures were normal throughout each scan. T2-weighted fast spin echo imaging provided better anatomic resolution and gray/white matter contrast than typically obtained at 1.5 T; T1-weighted images were less impressive. CONCLUSIONS With appropriate safety precautions, MRI of newborn infants undergoing intensive care is as feasible at 4.7 T as it is at 1.5 T; our initial studies produced T2-weighted fast spin echo images with more detail than commonly obtained at 1.5 T. Although T1-weighted images were not adequately informative, additional pulse sequence optimization may be advantageous. A smaller neonatal head coil should also permit greater flexibility in acquisition parameters and even more anatomic resolution and tissue contrast. In neonatal encephalopathy, interpretation of the T2-weighted pathologic detail in combination with comprehensive neurodevelopmental follow-up should improve prognostic accuracy and enable more patient-specific therapeutic interventions. In addition, more precise relationships between structural changes and functional impairment may be defined.

Abstract
OBJECTIVE Little information is available on long-term neurodevelopmental outcome of preterm infants with unilateral cerebral lesions detected by neonatal cranial ultrasound. This study aims to investigate the long-term outcome in a cohort of very preterm infants with unilateral cerebral lesions acquired in the perinatal period. METHODS A prospective cohort study of 668 preterm infants (<33 weeks gestation; birth years 1985-1991) at a single tertiary perinatal centre in the UK. All infants had serial cranial ultrasound examination in the neonatal period. Outcome was assessed at age 8 years with the Wechsler Intelligence Scales for Children (WISC-R), Test of Visuo-motor Integration (VMI) and the Test of Motor Impairment (TOMI). RESULTS Of the 668 infants, 369 infants had normal ultrasound scans. Two hundred and ninety nine children had bilateral parenchymal or non-parenchymal lesions (57 left-sided, 41 right-sided, 201 bilateral). Five hundred and thirty four (79%) children attended follow-up at age 8 years. Mean Full Scale IQ (FSIQ) was 101 (SD+/-16), 93 (SD+/-17), 102 (SD+/-17) and 91 (SD+/-21) for normal, left-sided, right-sided and bilateral lesion groups respectively. In all groups verbal IQ (VIQ) was higher than performance IQ (PIQ). Scores of FSIQ, VIQ and PIQ, VMI and TOMI were significantly different between the groups. After exclusion of children with parenchymal lesions, however, the difference was only significant for the TOMI scores. In all tests, children with left-sided lesions performed poorer than children with right-sided lesions. CONCLUSIONS In this cohort of preterm infants with unilateral cerebral lesions, verbal function was preserved over non-verbal function independently of the side of lesion. Furthermore, the results suggest that the neurodevelopmental outcome of children with left-sided lesions is less favourable than that of children with right-sided lesions.

Abstract
BACKGROUND Transient periventricular echodensities (PVE) in preterm infants affect neurodevelopmental outcome. OBJECTIVE To correlate the duration and grading of PVE with neurodevelopmental outcome. MATERIALS AND METHODS A retrospective, single-centre cohort study of infants with PVE diagnosed by ultrasonography from 1995 to 2000 with blinded grading and recognition of duration of PVE. RESULTS A total of 72 infants (median gestational age 32 weeks, median birth weight 1,668 g) were diagnosed as having PVE. Minor neurological abnormalities were diagnosed in seven (10%), cerebral palsy in six (8%), developmental delay in seven (10%), and mild mental retardation in two (3%) of the infants. Differences regarding adverse outcome were not significant between infants with severity grade 1 compared to severity grade 2 (16% and 22%, respectively). There was a significant increase in adverse neurodevelopmental outcome with increasing duration of PVE. Of 33 infants with duration of PVE<7 days, 1 (3%) had an adverse neurodevelopmental outcome, compared to 6 (24%) of 25 infants with a duration of PVE of 7-14 days, and 6 (43%) of 14 infants with a duration of PVE>14 days (P<0.002, RR 7.920, 95% CI 1.017-61.661; P<0.001, RR 14.143, 95% CI 1.871-106.895, respectively). CONCLUSION The duration, but not the grading, of transient PVE was significantly correlated with neurodevelopmental outcome.

Abstract
OBJECTIVE To quantify the effect of grades I-II intraventricular hemorrhage (IVH) on the neurosensory and cognitive outcomes of extremely low birth weight infants. STUDY DESIGN Of 706 extremely low birth weight infants without major malformations admitted to our center from 1992 to 2000, 537 survived to 20 months' corrected age (CA) and had cranial ultrasound studies performed, of whom 490 (91%) had complete neurodevelopmental assessments. Infants with severe cranial ultrasound abnormalities or meningitis were excluded, leaving a population of 362 infants, 258 of whom had a normal cranial ultrasound and 104 had an isolated grade I-II IVH. The groups had similar birth weight (808 vs 801 grams) and gestational age (26.5 vs 26.3 weeks). Outcomes of infants with normal cranial ultrasound were compared with those with grades I-II IVH at 20 months' CA. Outcomes included the Bayley Scales of Infant Development Mental Developmental Index (MDI) and major neurosensory abnormality. Logistic regression was used to assess the effect of grades I-II IVH on outcomes while adjusting for other risk factors. RESULTS Extremely low birth weight infants with grades I-II IVH had a significantly lower mean MDI score than infants with normal cranial ultrasound (74 +/- 16 vs 79 +/- 14, P = .006). They had higher rates of MDI <<70 (45% vs 25%; OR, 2.00; 95% CI, 1.20 to 3.30; P = .008), major neurologic abnormality (13% vs 5%; OR, 2.60; 95% CI, 1.06 to 6.36; P = .036), and neurodevelopmental impairment (47% vs 28%; OR, 1.83; 95% CI, 1.11 to 3.03; P = .018) at 20 months' CA, even when adjusting for confounding factors. CONCLUSIONS Extremely low birth weight infants with grades I-II IVH have poorer neurodevelopmental outcomes at 20 months' CA than infants with normal cranial ultrasound. Advanced radiologic imaging may indicate additional brain injury associated with grade I-II IVH, which could explain these outcomes.

Abstract
This study investigated whether in preterm children who had ventricular dilatation (VD) on neonatal cranial ultrasound outcome at age 8 years was influenced by the additional presence of germinal matrix haemorrhage--intraventricular haemorrhage (GMH-IVH). Six-hundred and ninety-nine preterm infants (<33 wks' gestation, mean 29.6 wks [SD 2.1]) with either normal cranial ultrasound (n=616; 286 females, 330 males), or with VD with (n=66; 32 females, 34 males) or without (n=17; 4 females, 13 males) GMH-IVH were enrolled in the study. At age 8 years outcome was assessed in 567 (81%) of the 699 children by neurological examination, the Test of Motor Impairment (TOMI), the test of Visuo-Motor Integration (VMI), and the Wechsler Intelligence Scales for Children. Results showed that the proportion of children with disabling impairments was higher in the group with VD and GMH-IVH. Performance on TOMI and VMI (even in those without disabling impairments) was poorer in those with VD and GMH-IVH than in children with normal scans or those with VD only. Children with VD and GMH-IVH had significantly lower performance IQ than children with normal ultrasound, whereas those with VD only were not different from those with normal scans. Results suggest the presence of subtle white matter injury that has not been identified by neonatal cranial ultrasound. Although this study did not investigate biochemical markers of haemorrhage, we hypothesize that non-protein-bound iron is likely to be a contributing factor to white matter damage in preterm infants.

Abstract
BACKGROUND Adverse cognitive and educational outcomes are often ascribed to perinatal hypoxia without good evidence. OBJECTIVE To investigate neurocognitive and behavioural outcomes after neonatal encephalopathy. METHODS Sixty five children with neonatal encephalopathy, identified using the Trent Neonatal Survey database for 1992-1994, were followed up at the age of 7 years. They were examined at school, with a classmate for those in mainstream school, by a paediatrician and a psychologist. Neonatal encephalopathy was graded as moderate or severe using published definitions. FINDINGS Fifteen children had major disability, all with cerebral palsy; eight were in special school with severe cognitive impairment (IQ<55). Disability was present in 6% of the moderate and 42% of the severe encephalopathy group. Of the 50 children without motor disability, cognitive scores were lowest in the severe group (mean IQ difference from peers -11.3 points (95% confidence interval (CI) -19.0 to -3.6) and with similar scores for the moderate group compared with classmates (mean difference -1.7 points (95% CI -7.3 to +3.9). Neuropsychological testing showed similar findings in all domains. In particular, memory and attention/executive functions were impaired in the severe group. Despite relatively small differences in performance of the moderate group, special educational needs were identified more often in both encephalopathy groups, associated with lower achievement on national curriculum attainment targets. INTERPRETATION After neonatal encephalopathy, subtle cognitive impairments are found in the absence of neuromotor impairment. Subtle impairments are found more commonly after a more severe clinical course. Studies of brain protection strategies require long term follow up to study effects on cognitive outcome.
