Abstract
BACKGROUND Laryngeal mask airway surfactant administration (S-LMA) has the potential benefit of surfactant administration whilst avoiding endotracheal intubation and ventilation, ventilator-induced lung injury and bronchopulmonary dysplasia (BPD). OBJECTIVES To evaluate the benefits and harms of S-LMA either as prophylaxis or treatment (rescue) compared to placebo, no treatment, or intratracheal surfactant administration via an endotracheal tube (ETT) with the intent to rapidly extubate (InSurE) or extubate at standard criteria (S-ETT) or via other less-invasive surfactant administration (LISA) methods on morbidity and mortality in preterm infants with or at risk of respiratory distress syndrome (RDS). SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, CINAHL, and three trial registries in December 2022. SELECTION CRITERIA Randomised controlled trials (RCTs), cluster- or quasi-RCTs of S-LMA compared to placebo, no treatment, or other routes of administration (nebulised, pharyngeal instillation of surfactant before the first breath, thin endotracheal catheter surfactant administration or intratracheal surfactant instillation) on morbidity and mortality in preterm infants at risk of RDS. We considered published, unpublished and ongoing trials. DATA COLLECTION AND ANALYSIS Two review authors independently assessed studies for inclusion and extracted data. We used GRADE to assess the certainty of the evidence. MAIN RESULTS We included eight trials (seven new to this update) recruiting 510 newborns. Five trials (333 infants) compared S-LMA with surfactant administration via ETT with InSurE. One trial (48 infants) compared S-LMA with surfactant administration via ETT with S-ETT, and two trials (129 infants) compared S-LMA with no surfactant administration. We found no studies comparing S-LMA with LISA techniques or prophylactic or early S-LMA. S-LMA versus surfactant administration via InSurE S-LMA may have little or no effect on the composite outcome of death or BPD at 36 weeks' postmenstrual age (risk ratio (RR) 1.50, 95% confidence interval (CI) 0.27 to 8.34, I 2 = not applicable (NA) as 1 study had 0 events; risk difference (RD) 0.02, 95% CI -0.07 to 0.10; I 2 = 0%; 2 studies, 110 infants; low-certainty evidence). There may be a reduction in the need for mechanical ventilation at any time (RR 0.53, 95% CI 0.36 to 0.78; I 2 = 27%; RD -0.14, 95% CI -0.22 to -0.06, I 2 = 89%; number needed to treat for an additional beneficial outcome (NNTB) 7, 95% CI 5 to 17; 5 studies, 333 infants; low-certainty evidence). However, this was limited to four studies (236 infants) using analgesia or sedation for the InSurE group. There was little or no difference for air leak during first hospitalisation (RR 1.39, 95% CI 0.65 to 2.98; I 2 = 0%; 5 studies, 333 infants (based on 3 studies as 2 studies had 0 events); low-certainty evidence); BPD among survivors to 36 weeks' PMA (RR 1.28, 95% CI 0.47 to 3.52; I 2 = 0%; 4 studies, 264 infants (based on 3 studies as 1 study had 0 events); low-certainty evidence); or death (all causes) during the first hospitalisation (RR 0.28, 95% CI 0.01 to 6.60; I 2 = NA as 2 studies had 0 events; 3 studies, 203 infants; low-certainty evidence). Neurosensory disability was not reported. Intraventricular haemorrhage ( IVH) grades III and IV were reported among the study groups (1 study, 50 infants). S-LMA versus surfactant administration via S-ETT No study reported death or BPD at 36 weeks' PMA. S-LMA may reduce the use of mechanical ventilation at any time compared with S-ETT (RR 0.47, 95% CI 0.31 to 0.71; RD -0.54, 95% CI -0.74 to -0.34; NNTB 2, 95% CI 2 to 3; 1 study, 48 infants; low-certainty evidence). We are very uncertain whether S-LMA compared with S-ETT reduces air leak during first hospitalisation (RR 2.56, 95% CI 0.11 to 59.75), IVH grade III or IV (RR 2.56, 95% CI 0.11 to 59.75) and death (all causes) during the first hospitalisation (RR 0.17, 95% CI 0.01 to 3.37) (1 study, 48 infants; very low-certainty evidence). No study reported BPD to 36 weeks' PMA or neurosensory disability. S-LMA versus no surfactant administration Rescue surfactant could be used in both groups. There may be little or no difference in death or BPD at 36 weeks (RR 1.65, 95% CI 0.85 to 3.22; I 2 = 58%; RD 0.08, 95% CI -0.03 to 0.19; I 2 = 0%; 2 studies, 129 infants; low-certainty evidence). There was probably a reduction in the need for mechanical ventilation at any time with S-LMA compared with nasal continuous positive airway pressure without surfactant (RR 0.57, 95% CI 0.38 to 0.85; I 2 = 0%; RD -0.24, 95% CI -0.40 to -0.08; I 2 = 0%; NNTB 4, 95% CI 3 to 13; 2 studies, 129 infants; moderate-certainty evidence). There was little or no difference in air leak during first hospitalisation (RR 0.65, 95% CI 0.23 to 1.88; I 2 = 0%; 2 studies, 129 infants; low-certainty evidence) or BPD to 36 weeks' PMA (RR 1.65, 95% CI 0.85 to 3.22; I 2 = 58%; 2 studies, 129 infants; low-certainty evidence). There were no events in either group for death during the first hospitalisation (1 study, 103 infants) or IVH grade III and IV (1 study, 103 infants). No study reported neurosensory disability. AUTHORS' CONCLUSIONS In preterm infants less than 36 weeks' PMA, rescue S-LMA may have little or no effect on the composite outcome of death or BPD at 36 weeks' PMA. However, it may reduce the need for mechanical ventilation at any time. This benefit is limited to trials reporting the use of analgesia or sedation in the InSurE and S-ETT groups. There is low- to very-low certainty evidence for no or little difference in neonatal morbidities and mortality. Long-term outcomes are largely unreported. In preterm infants less than 32 weeks' PMA or less than 1500 g, there are insufficient data to support or refute the use of S-LMA in clinical practice. Adequately powered trials are required to determine the effect of S-LMA for prevention or early treatment of RDS in extremely preterm infants. S-LMA use should be limited to clinical trials in this group of infants.

Early Hum Dev 2023; 180:105756.

Abstract
BACKGROUND There is lack of evidence synthesis on the global consequences of bronchopulmonary dysplasia (BPD) in adolescence. AIM Assess the impact of bronchopulmonary dysplasia on respiratory and non-respiratory outcomes in adolescents. METHODS A systematic review of studies assessing the outcomes of adolescents aged 10 to 19 years-old with BPD was conducted. We independently screened studies published until 6th March 2023 in PubMed® and Scopus® databases. Data on methodologic design, sample descriptive and findings were extracted from each study. Risk of bias was assessed using quality assessment tools. RESULTS Thirty-one studies were included. Adolescents with a history of BPD present with more respiratory symptoms (wheezing, respiratory exacerbations, need for respiratory medication) and twenty-five studies showed a reduction in pulmonary function, with varying impact according to BPD severity and no differences before and after the surfactant era. Spirometry evaluation throughout the years is not consensual, but methacholine and salbutamol response in BPD groups is increased compared to non-BPD groups. Markers of eosinophilic airway inflammation are not increased as in asthma patients. Exercise potential is identical, but data regarding physical capacity and activity are inconsistent. More frequent radiologic abnormalities translate into higher high-resolution computed tomography scores, with linear (72.2 %) and triangular subpleural opacities (58.3 %) as the most common findings. There is a higher risk for special needs in education, but quality of life seems to be equal to non-BPD adolescents. CONCLUSIONS BPD negatively impacts both pulmonary and non-pulmonary outcomes in adolescents.

Motor Optimality Scores are significantly lower in a population of high-risk infants than in infants born moderate-late preterm. Early Hum Dev 2022; 174:105684. [PMID: 36209602 PMCID: PMC10243476 DOI: 10.1016/j.earlhumdev.2022.105684] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2022] [Revised: 09/27/2022] [Accepted: 09/28/2022] [Indexed: 11/03/2022]
Abstract
BACKGROUND The Motor Optimality Score-Revised (MOS-R) is a detailed scoring of the General Movement Assessment (GMA), measuring the spontaneous behaviors of infants. Infants born moderate-late preterm are not traditionally followed in high-risk clinics, but have increased risk of neurodevelopmental disability. AIMS Compare MOS-R at 3 months corrected age (CA) in high-risk (HR; very preterm or abnormal neuroimaging) infants to infants born moderate-late preterm (MLP). STUDY DESIGN In this prospective cohort study, parents of enrolled infants created video recordings using an app at 3 months CA. Videos were scored with the General Movement Assessment (GMA) and MOS-R. MOS-R scores were divided into "higher-risk" (≤19) and "lower-risk" (≥20). SUBJECTS 181 infants born MLP or categorized as HR. RESULTS Among enrolled infants, 68 (38 %) were in the MLP group, and 113 infants were in the HR group. The HR group had 3.8 increased odds of having an aberrant GMA score compared to the MLP group (p < 0.01, 95 % CI 1.38-10.52). The HR group had significantly lower MOS-R scores (mean 20) than the MLP group (mean 24; p < 0.001; 95%CI 3.3-7.3). The HR group had 11.2 increased odds of having a higher-risk MOS-R score (95%CI 2.5-47.6, p < 0.001) than MLP group. Infants were most likely to have a lower MOS-R score if they had any of the following: VP shunt placement, periventricular leukomalacia, or bronchopulmonary dysplasia. CONCLUSIONS Aberrant GMA and higher-risk MOS-R scores were more common in infants at high-risk, reflecting history of brain lesions and younger gestational age at birth.

Abstract
Preterm infants with bronchopulmonary dysplasia (BPD), and particularly those who develop the most severe forms of chronic lung disease during the neonatal period, are at high risk for poor developmental outcomes throughout childhood. Infants who require mechanical ventilation at 36 weeks post-menstrual age have significantly increased odds for cerebral palsy, developmental delay at 2 years, and poor academic achievement and low intelligence quotient in adolescence. Over the past several decades, many therapies and care strategies, including steroids, continuous positive airway pressure, surfactant, and other medications have been introduced into clinical practice. These approaches have changed the epidemiology of BPD in very preterm infants. However, BPD remains common and strongly associated with poor development throughout childhood. Only caffeine has been proven to reduce BPD and improve childhood developmental outcomes. In future research, it will be essential to better understand the developmental sequelae of BPD beyond school age and to test interventions to improve developmental trajectories in this population. As new management strategies for BPD are developed, it will be essential to rigorously evaluate both short-term and long-term effects before they are introduced into routine neonatal practice.

Abstract
Improving the adverse neurodevelopmental outcomes associated with prematurity is a priority. In the large international Caffeine for Apnea of Prematurity trial, caffeine improved survival without neurodevelopmental disability at 18 months and demonstrated long term safety up to 11 years. Caffeine is an adenosine receptor antagonist with effects on the brain, lung and other systems. The benefits of caffeine may be primary neuroprotection or reduction of risk factors for impairment, especially bronchopulmonary dysplasia. The effects of caffeine vary with age and dose. Animal data show risks of loss of neuronal protection from hypoxia. Treatment with earlier and higher dose caffeine may be beneficial but concerns remain.

Abstract
Introduction To evaluate the consequences of bronchopulmonary dysplasia (BPD) on academic outcomes and healthcare use in adolescents born very preterm. Methods This cohort study included 15-year-old adolescents born very preterm (< 32 weeks) between 2011 and 2013, with and without BPD, and controls born full term. Data regarding academic performance, current medical follow-up, and family characteristics were collected. Multivariate logistic regression was used to quantify relationships between academic outcomes and BPD. Results From the 1341 children included in the initial cohort, 985 adolescents were eligible and 351 included (55 preterms with a history of BPD, 249 without, and 47 controls). Among adolescents born very preterm, a history of BPD was associated with a higher risk to attend a school for children with special needs (p < 0.05) and to have repeated a grade (p = 0.01). It was also associated with an increased number of medical and paramedical consultations. A history of BPD was not associated with the parents’ employment status, family structure, or the presence of younger siblings. Conclusion This study highlights that a history of BPD is associated with poorer academic outcomes and high healthcare use in adolescence.

Abstract
Bronchopulmonary dysplasia (BPD) is a common complication of extreme prematurity, and its rate is not improving, despite advances in perinatal intensive care. Children with BPD diagnosed in the neonatal period have higher risks for hospitalizations for respiratory problems over the first few years of life, and they have more asthma in later childhood. Neonates diagnosed with BPD have substantial airway obstruction on lung function testing in later childhood and early adulthood, and many are destined to develop adult chronic obstructive pulmonary disease. Survivors with neonatal BPD have more adverse motor function, worse cognitive development and poorer academic progress than those without BPD. Long-term outcomes for children born extremely preterm will improve if the rate of BPD can be substantially reduced.

Abstract
The rate of bronchopulmonary dysplasia (BPD) in preterm infants is increasing; this trend reflects, in part, improved survival among extremely premature infants. BPD is associated with adverse developmental and medical outcomes in early childhood and at least through school age. Therefore, BPD imposes a significant burden on infants and children, their families, and society. Many interventions to decrease BPD and the sequelae of BPD have been studied; few to date have been proved to decrease both BPD and later disability.

Abstract
BACKGROUND Advances in neonatal healthcare have resulted in decreased mortality after preterm birth but have not led to parallel decreases in morbidity. Academic performance provides insight in the outcomes and specific difficulties and needs of preterm children. OBJECTIVE To study academic performance in preterm children born in the antenatal steroids and surfactant era and possible moderating effects of perinatal and demographic factors. DESIGN PubMed, Web of Science and PsycINFO were searched for peer-reviewed articles. Cohort studies with a full-term control group reporting standardised academic performance scores of preterm children (<37 weeks of gestation) at age 5 years or older and born in the antenatal steroids and surfactant era were included. Academic test scores and special educational needs of preterm and full-term children were analysed using random effects meta-analysis. Random effects meta-regressions were performed to explore the predictive role of perinatal and demographic factors for between-study variance in effect sizes. RESULTS The 17 eligible studies included 2390 preterm children and 1549 controls. Preterm children scored 0.71 SD below full-term peers on arithmetic (p<0.001), 0.44 and 0.52 SD lower on reading and spelling (p<0.001) and were 2.85 times more likely to receive special educational assistance (95% CI 2.12 to 3.84, p<0.001). Bronchopulmonarydysplasia explained 44% of the variance in academic performance (p=0.006). CONCLUSION Preterm children born in the antenatal steroids and surfactant era show considerable academic difficulties. Preterm children with bronchopulmonarydysplasia are at particular risk for poor academic outcome.

Abstract
OBJECTIVES To compare neurocognitive, language, executive function, academic achievement, neurologic and behavioral outcomes, and quality of life at age 10 years in children born extremely preterm who developed bronchopulmonary dysplasia (BPD) to children who did not develop BPD. METHODS The Extremely Low Gestational Age Newborns study population included 863 children born extremely preterm whose BPD status before discharge was known had an IQ (Differential Ability Scales II [DAS II]) assessment at 10 years. We evaluated the association of BPD with any cognitive (DAS II), executive function (NEuroPSYchological Assessment II), academic achievement (Wechsler Individual Achievement Test-III and Oral and Written Language Scales [OWLS]) as well as social dysfunctions (Social Responsiveness Scale). We used logistic regression models, adjusting for potential confounding factors, to assess the strength of association between the severity of BPD and each outcomes. RESULTS Three hundred and seventy-two (43%) children were oxygen-dependent at 36 weeks postconception age, whereas an additional 78 (9%) were also oxygen- and ventilator-dependent. IQ scores 2 or more SDs below the expected mean (ie, z scores ≤-2) occurred twice as commonly among children who had BPD as among those who did not. Children with severe BPD consistently had the lowest scores on DAS II, OWLS, Wechsler Individual Achievement Test-III, NEuroPSYchological Assessment II, and Social Responsiveness Scale assessments. CONCLUSIONS Among 10-year-old children born extremely preterm, those who had BPD were at increased risk of cognitive, language, and executive dysfunctions; academic achievement limitations; social skill deficits; and low scores on assessments of health-related quality of life.

Abstract
Multiple studies have reported that individuals with low birth weights (LBW, <2500 g) have a lower intelligence quotient (IQ) than those with normal birth weights (NBW, ≥2500 g). Based on 57 eligible individual studies including 12,137 participants, we performed a meta-analysis to estimate the association between low birth weight and individuals' IQ scores (IQs). The pooled weight mean difference (WMD) in IQs between NBW and LBW individuals was 10 (95% CI 9.26-11.68). The WMD was stable regardless of age. No publication bias was detected. The mean IQs of the extremely low birth weight (ELBW, <1000 g), very low birth weight (VLBW, 1000-1499 g), moderately low birth weight (MLBW, 1500-2499 g) and NBW individuals were 91, 94, 99 and 104, respectively. Additionally, the WMD in IQs with NBW were 14, 10 and 7 for ELBW, VLBW, and MLBW individuals, respectively. Two studies permitted estimates of the influence of social determinants of health to the discrepancy in IQs, which was 13%. Since IQ is inherited and influenced by environmental factors, parental IQs and other factors contribute to residual confounding of the results. As the conclusion was based on population studies, it may not be applicable to a single individual.

Abstract
Soybean oil-based intravenous fat emulsions (IVFEs) have been the predominant parenteral nutrition IVFE used in the United States for neonates over the past 45 years. Even though this emulsion has proven useful in supplying infants with energy for growth and essential fatty acids, there have been concerns over its composition in the development of several morbidities, ranging from sepsis to liver disease, bronchopulmonary dysplasia, and impaired neurodevelopment and growth. The exact mechanisms that drive these morbidities in preterm infants are multifactorial, but potential contributors include high ω-6 (n-6) fatty acid composition, low docosahexaenoic acid and antioxidant supplementation, and the presence of potentially harmful nonnutritive components (eg, phytosterols). To address these issues, new-generation IVFEs with various types and amounts of fat have been developed containing greater amounts of the medium-chain fatty acids, long-chain polyunsaturated fatty acid, docosahexaenoic acid, lower concentrations of ω-6 polyunsaturated fatty acids, supplemental vitamin E, and low or negligible amounts of phytosterols. This review examines the clinical outcomes associated with different morbidities of parenteral nutrition in neonates who have received either soybean oil-based or new-generation IVFEs and addresses whether the proposed benefits of new-generation IVFEs have improved outcomes in the neonatal population.

Abstract
BACKGROUND Bronchopulmonary dysplasia (BPD), also known as chronic lung disease of prematurity or chronic neonatal lung disease, is a major cause of respiratory illness in premature babies. Newborn babies survive at gestational ages of 23 to 26 weeks, earlier than when BPD was first described. New mechanisms of lung injury have therefore emerged and the clinical and pathological characteristics of pulmonary involvement have changed. PURPOSE Improved neonatal intensive care unit modalities have increased survival rates; the overall prevalence of the condition, however, has not changed. Management of evolving BPD aims at minimizing lung injury. Management of established, especially severe BPD, still poses significant clinical challenge as these babies need long-term oxygen therapy (LTOT) for variable length of time. We aim to give an overview of management of established BPD with particular focus on weaning home oxygen therapy at our local center in the United Kingdom. SEARCH AND RESULTS On the basis of most recent evidence, we concluded that an integrated pathway for managing babies on LTOT is very important after discharge from neonatal unit. IMPLICATIONS FOR PRACTICE A structured weaning pathway for premature babies on home oxygen improves outcome. IMPLICATIONS FOR RESEARCH The management of severe BPD and related complications, particularly during the first 2 years of life, remains a continuing challenge for parents and healthcare providers. The most beneficial respiratory support strategy to minimize lung injury and/or promote lung healing remains unclear and requires further investigation.

Abstract
Bronchopulmonary dysplasia (BPD) is among the most common and serious sequelae of preterm birth. BPD affects at least one-quarter of infants born with birth weights less than 1500 g. The incidence of BPD increases with decreasing gestational age and birth weight. Additional important risk factors include intrauterine growth restriction, sepsis, and prolonged exposure to mechanical ventilation and supplemental oxygen. The diagnosis of BPD predicts multiple adverse outcomes including chronic respiratory impairment and neurodevelopmental delay. This review summarizes the diagnostic criteria, incidence, risk factors, and long-term outcomes of BPD.

Abstract
UNLABELLED We tested the hypothesis that the use of supplemental oxygen (sO2) at discharge from the NICU in extremely preterm neonates is associated with a greater risk of neurodevelopmental impairment (NDI) at 18 months corrected gestational age (CGA) than the risk of NDI of those neonates discharged in room air. Four hundred twenty-four charts were retrospectively reviewed from infants born at <27 weeks and transferred to Nationwide Children's Hospital from December 1, 2004 to June 14, 2010. Use of sO2 was evaluated on day of life (dol) 28, at 36 weeks post-menstrual age (PMA), and at discharge. Logistic regression was used to identify postnatal risk factors associated with sO2 at discharge and NDI. At dol 28, 96 % of surviving patients received sO2, and therefore had bronchopulmonary dysplasia (BPD) by definition from a National Institutes of Child Health and Human Development workshop. At 36 weeks PMA, 89 % continued on sO2 (moderate/severe BPD), and at discharge, 74 % continued on sO2. When factors associated with NDI were examined, the need for mechanical ventilation ≥28 days (adjOR = 3.21, p = 0.01), grade III-IV intraventricular hemorrhage (IVH) (adjOR = 4.61, p < 0.01), and discharge at >43 weeks PMA (adjOR = 2.12, p = 0.04) were the strongest predictors of NDI at 18 months CGA. There was no difference in Bayley Scales of Infant Development, third edition composite scores between patients with no/mild BPD and patients with moderate/severe BPD (cognitive p = 0.60, communication p = 0.53, motor p = 0.19) or those scores between patients on and off oxygen at discharge (cognitive p = 0.58, communication p = 0.70, motor p = 0.62). CONCLUSIONS The need for sO2 at discharge is not associated with an increased risk of NDI in these patients. The strongest predictors of poor neurodevelopmental outcome in this population were prolonged positive pressure support, grade III-IV IVH, and discharge at >43 weeks PMA.

Abstract
BACKGROUND Nebulised surfactant has the potential to deliver surfactant to the infant lung with the goal of avoiding endotracheal intubation and ventilation, ventilator-induced lung injury and bronchopulmonary dysplasia (BPD). OBJECTIVES To determine the effect of nebulised surfactant administration either as prophylaxis or treatment compared to placebo, no treatment or intratracheal surfactant administration on morbidity and mortality in preterm infants with, or at risk of, respiratory distress syndrome (RDS). SEARCH METHODS Searches were performed of CENTRAL (The Cochrane Library, January 2012), MEDLINE and PREMEDLINE (1950 to January 2012), EMBASE (1980 to January 2012) and CINAHL (1982 to January 2012), as well as proceedings of scientific meetings, clinical trial registries, Google Scholar and reference lists of identified studies. Expert informants and surfactant manufacturers were contacted. SELECTION CRITERIA Randomised, cluster-randomised or quasi-randomised controlled trials of nebulised surfactant administration compared to placebo, no treatment, or other routes of administration (laryngeal, pharyngeal instillation of surfactant before the first breath, thin endotracheal catheter surfactant administration or intratracheal surfactant instillation) on morbidity and mortality in preterm infants at risk of RDS. We considered published, unpublished and ongoing trials. DATA COLLECTION AND ANALYSIS Two review authors independently assessed studies for eligibility and quality, and extracted data. MAIN RESULTS No studies of prophylactic or early nebulised surfactant administration were found. A single small study of late rescue nebulised surfactant was included. The study is of moderate risk of bias. The study enrolled 32 preterm infants born < 36 weeks' gestation with RDS on nasal continuous positive airway pressure (nCPAP). The study reported no significant difference between nebulised surfactant administration compared to no treatment groups in chronic lung disease (risk ratio (RR) 5.00; 95% confidence interval (CI) 0.26 to 96.59) or other outcomes (oxygenation 1 to 12 hours after randomisation, need for mechanical ventilation, days of mechanical ventilation or continuous positive airways pressure (CPAP) or days of supplemental oxygen). No side effects of the nebulised surfactant therapy or aerosol inhalation were reported. AUTHORS' CONCLUSIONS There are insufficient data to support or refute the use of nebulised surfactant in clinical practice. Adequately powered trials are required to determine the effect of nebulised surfactant administration for prevention or early treatment of RDS in preterm infants. Nebulised surfactant administration should be limited to clinical trials.

DESIGN AND METHODS The World Health Organization International Classification of Functioning, Disability and Health model framed functioning and participation domains and contextual factors. Assessment included cognition, executive functioning, academic achievement, personal functioning, community participation, and social involvement. RESULTS Socioeconomic status, not prematurity, impacted cognitive and academic outcomes. Across neonatal morbidities, male gender and social disadvantage are key determinants of cognitive, academic, and social functioning.

Abstract
OBJECTIVE Changes in nutritional strategies over the past decade have been shown to improve postnatal growth in extremely low birth weight (ELBW) infants. We showed 10 years ago that the majority of these ELBW infants with bronchopulmonary dysplasia (BPD) suffer postnatal growth failure. We theorized that recent changes in nutritional support strategies would positively affect growth outcomes in ELBW infants with BPD. STUDY DESIGN A retrospective study of 88 ELBW infants with BPD. Nutritional data, postnatal growth and BPD severity were compared across three cohorts: (1) weight gain ≤14 g kg(-1) per day, (2) 14.1 to 16 g kg(-1) per day and (3) ≥16 g kg(-1) per day from return to birth weight through discharge. We also compared these to a historical cohort. RESULT In all, 73% of current subjects grew at or above fetal rates. There was less extrauterine growth restriction (EUGR) by weight and head circumference for those ELBW infants with BPD receiving higher amounts of protein. Aggressive early TPN and receipt of caloric-dense milk seemed to be the 'new' nutritional strategies improving growth for current ELBW infants with BPD compared with those 10 years ago. CONCLUSION Despite a diagnosis of BPD, improved nutritional strategies have enhanced postnatal growth in infants at high risk for EUGR.

Abstract
Standard approaches to teaching the management of psychosocial issues in pediatrics--visits to community-based organizations and stand-alone block rotations in developmental-behavioral pediatrics and community pediatrics--neither expose residents to models of interdisciplinary collaboration between faculty preceptors and community providers nor take advantage of the efficacy of learning in continuity clinics. The authors describe their project, developed from an existing Community Pediatrics Training Initiative with long-standing relationships with a domestic violence shelter, a community center for Latino families, and a special needs resource organization for parents. They lay out in detail the project's innovative use of partners from community-based organizations, colocated within pediatric continuity clinics, who teach both residents and faculty about community resources and linkages with multidisciplinary providers. The authors present lessons learned by faculty preceptors, residents, the community partners, and project staff that can guide future applications of this model in other residency training programs. Faculty and residents indicated an increased awareness of available community resources and how linkages can be incorporated into pediatric outpatient visits. Community partners identified keys to successful co-teaching, including readiness to adopt an assertive communication style and frequent presence in the clinics. Project staff recognized the challenges of staff turnover at community-based organizations and the need to choose community partners with expertise that fits the sociodemographic issues of the clinic's patients.

Abstract
BACKGROUND Laryngeal mask airway (LMA) administration is one way of delivering surfactant to the infant lung, with the potential benefit of avoiding endotracheal intubation and ventilation, ventilator induced lung injury and bronchopulmonary dysplasia (BPD). OBJECTIVES To determine the effect of LMA surfactant administration either as prophylaxis or treatment compared to placebo, no treatment, or intratracheal surfactant administration on morbidity and mortality in preterm infants with, or at risk of, respiratory distress syndrome (RDS). SEARCH STRATEGY We searched CENTRAL (The Cochrane Library, October 2010), MEDLINE and PREMEDLINE (1950 to October 2010), EMBASE (1980 to October 2010) and CINAHL (1982 to October 2010). We also searched proceedings of scientific meetings, clinical trial registries, Google Scholar and reference lists of identified studies, as well as contacting expert informants and surfactant manufacturers. SELECTION CRITERIA Randomised, cluster-randomised or quasi-randomised controlled trials of laryngeal mask surfactant administration compared to placebo, no treatment, or other routes of administration (nebulised, pharyngeal instillation of surfactant before the first breath, thin endotracheal catheter surfactant administration or intratracheal surfactant instillation) on morbidity and mortality in preterm infants at risk of RDS. We considered published, unpublished and ongoing trials. DATA COLLECTION AND ANALYSIS Two review authors independently assessed studies for eligibility and quality, and extracted data. MAIN RESULTS We found no studies of prophylactic or early LMA surfactant administration. A single small study of late rescue LMA surfactant was identified as eligible for inclusion. The study enrolled 26 preterm infants born ≥ 1200 g with RDS on continuous positive airway pressure (nCPAP). LMA surfactant administration compared to no treatment resulted in a reduction in mean FiO(2) required to maintain oxygen saturation between 88% and 92% for 12 hours after the intervention. No significant difference was reported in subsequent mechanical ventilation and endotracheal surfactant, pneumothorax, days on intermittent positive airway pressure (IPPV), and days on IPPV or oxygen. AUTHORS' CONCLUSIONS There is evidence from a single small trial that LMA surfactant administration in preterm infants ≥ 1200 g with established RDS may have a short term effect in reducing oxygen requirements although the study is underpowered to detect important clinical effects. Adequately powered trials are required to determine the effect of LMA surfactant administration for prevention or treatment of RDS in preterm infants. LMA surfactant administration should be limited to clinical trials.

Abstract
BACKGROUND Clara cell secretary protein (CCSP) is an immune-modulating and anti-inflammatory agent. CCSP is available synthetically as recombinant human Clara cell protein (rhCC10). It has been shown in animal models to reduce lung injury, improve pulmonary compliance and oxygenation, decrease systemic inflammation and up-regulate surfactant protein and vascular endothelial growth factor expression. These properties makes intratracheally administered CCSP a potential agent in prevention of chronic lung disease (CLD). OBJECTIVES To determine the effect of intratracheal CCSP administration compared to placebo or no treatment on morbidity and mortality in preterm infants with or at risk of respiratory distress syndrome (RDS). SEARCH STRATEGY We searched CENTRAL (The Cochrane Library, October 2010), MEDLINE and PREMEDLINE (1950 to October 2010), EMBASE (1980 to October 2010) and CINAHL (1982 to October 2010). We searched proceedings of scientific meetings, Google Scholar and reference lists of identified studies, and contacted expert informants and surfactant manufacturers. SELECTION CRITERIA Published, unpublished and ongoing randomised controlled, cluster-randomised or quasi-randomised trials of intratracheal CCSP administration, compared to placebo or no treatment on morbidity and mortality in preterm infants at risk of RDS. DATA COLLECTION AND ANALYSIS Two authors independently assessed studies for eligibility and quality, and extracted data. MAIN RESULTS One pilot study was identified and included. This study enrolled 22 preterm infants 700 to 1300g with established RDS who required ventilation for surfactant administration. Infants received one intratracheal dose of placebo (n = 7), 1.5 mg/kg (n = 8) or 5 mg/kg (n = 7) rhCC10 within four hours of surfactant treatment. At either dose of rhCC10, no significant difference was reported in CLD (36 weeks postmenstrual age or 28 days), mortality, intraventricular haemorrhage, periventricular leukomalacia, patent ductus arteriosus, necrotising enterocolitis, sepsis or days supplemental oxygen compared to placebo. A significant increase in days mechanical ventilation was reported for infants receiving rhCC10 5mg/kg (mean difference 12.00, 95% confidence interval 0.39 to 23.61) but not at the lower dose. The study reported that a single intratracheal dose of rhCC10 was well tolerated and resulted in a significant reduction in tracheal aspirate neutrophil and total cell count, and lung protein concentration. There was no significant difference reported in tracheal aspirate cytokine levels between groups. AUTHORS' CONCLUSIONS There are insufficient data to determine the role of rhCC10 in clinical practice. Further studies are required to determine if rhCC10 reduces lung inflammation in infants at risk of CLD, and to determine dose and dosing strategy.

Abstract
BACKGROUND Intrapartum pharyngeal instillation of surfactant before the first breath may result in surfactant administration to the infant lung, with the potential benefit of avoiding endotracheal intubation and ventilation, ventilator induced lung injury and bronchopulmonary dysplasia. OBJECTIVES To determine the effect of pharyngeal instillation of surfactant before the first breath compared to placebo, no treatment or intratracheal surfactant administration followed by intermittent positive pressure ventilation (IPPV) on morbidity and mortality in preterm infants at risk of respiratory distress syndrome (RDS). SEARCH STRATEGY Searches were made of CENTRAL (The Cochrane Library, to September 2010), MEDLINE and PREMEDLINE (1950 to September 2010), EMBASE (1980 to 2010) and CINAHL (1982 to 2010). This strategy was supplemented by searches of proceedings of scientific meetings, Google Scholar and reference lists of identified studies, as well as contact with expert informants and surfactant manufacturers. SELECTION CRITERIA Published, unpublished and ongoing randomised controlled or quasi-randomised trials (using individual or cluster allocation) of pharyngeal instillation of surfactant before the first breath compared to placebo or no treatment, or intratracheal surfactant instillation followed by IPPV, on morbidity and mortality in preterm infants at risk of RDS. DATA COLLECTION AND ANALYSIS Two authors independently assessed study eligibility and quality. MAIN RESULTS No published, unpublished or ongoing trials that met the inclusion criteria for this review were found. AUTHORS' CONCLUSIONS There were no data from randomised controlled or quasi-randomised trials that evaluated the effect of intrapartum instillation of pharyngeal surfactant before the first breath. Evidence from animal and observational human studies suggest that pharyngeal instillation of surfactant before the first breath is potentially safe, feasible and may be effective. Well designed trials are needed.

Two-year neurodevelopmental outcomes of ventilated preterm infants treated with inhaled nitric oxide. J Pediatr 2010; 156:556-61.e1.

Abstract
OBJECTIVE In a randomized multi-center trial, we demonstrated that inhaled nitric oxide begun between 7 and 21 days and given for 24 days significantly increased survival without bronchopulmonary dysplasia (BPD) in ventilated premature infants weighing <1250 g. Because some preventative BPD treatments are associated with neurodevelopmental impairment, we designed a follow-up study to assess the safety of nitric oxide. STUDY DESIGN Our hypothesis was that inhaled nitric oxide would not increase neurodevelopmental impairment compared with placebo. We prospectively evaluated neurodevelopmental and growth outcomes at 24 months postmenstrual age in 477 of 535 surviving infants (89%) enrolled in the trial. RESULTS In the treated group, 109 of 243 children (45%) had neurodevelopmental impairment (moderate or severe cerebral palsy, bilateral blindness, bilateral hearing loss, or score <70 on the Bayley Scales II), compared with 114 of 234 (49%) in the placebo group (relative risk, 0.92; 95% CI, 0.75-1.12; P = .39). No differences on any subcomponent of neurodevelopmental impairment or growth variables were found between inhaled nitric oxide or placebo. CONCLUSIONS Inhaled nitric oxide improved survival free of BPD, with no adverse neurodevelopmental effects at 2 years of age.

Abstract
BACKGROUND Early surfactant reduces mortality and pulmonary complications in preterm infants with respiratory distress syndrome. However, current surfactant administration strategies require endotracheal intubation with or without continued mechanical ventilation. Bronchopulmonary dysplasia and chronic lung disease (CLD) are associated with mechanical ventilation and potentially life-long effects. Non-invasive methods of surfactant administration including intra-amniotic surfactant may avoid endotracheal intubation and mechanical ventilation, potentially preventing development of CLD. OBJECTIVES To determine if intra-amniotic instillation of surfactant for women at risk of preterm birth, compared to placebo or no treatment or post-delivery tracheal surfactant instillation, reduces morbidity or mortality, or both, in preterm infants. If intra-amniotic instillation is effective, in subgroup analysis to determine the effect of 1) gestational age; 2) type of surfactant; 3) dose; 4) timing; 5) indication; and 6) multiple pregnancy. SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (August 2009), MEDLINE (1950-August 2009), handsearched the Proceedings of Pediatric Academic Societies (American Pediatric Society, Society for Pediatric Research and European Society for Pediatric Research) from 1990-2009 in Pediatric Research Journal and Abstracts online and the Proceedings of Perinatal Society of Australia and New Zealand (PSANZ) (1996-2009). We also searched the Science Citation Index (Web of Science) (August 2009) and checked reference lists of identified studies. We contacted Abbott Laboratories, Inc for unpublished studies. SELECTION CRITERIA Published, unpublished and ongoing randomised controlled, cluster-randomised or quasi-randomised trials of intra-amniotic instillation of surfactant for women at risk of preterm birth, compared to placebo or no treatment or post-delivery tracheal surfactant instillation. DATA COLLECTION AND ANALYSIS Three review authors independently assessed study eligibility and quality. MAIN RESULTS We found no trials were found met the inclusion criteria for this review. AUTHORS' CONCLUSIONS We identified no randomised trials that evaluated the effect of intra-amniotic instillation of surfactant for women at risk of preterm birth. Evidence from animal and observational human studies suggest that intra-amniotic surfactant administration is potentially safe, feasible and effective. Well designed trials of intra-amniotic instillation of surfactant for women at risk of preterm birth are needed.

Abstract
As more very preterm infants survive, more survivors will have bronchopulmonary dysplasia (BPD). Children with BPD have higher rates of cognitive, educational and behavioural impairments, and also reduced lung function, through childhood and into early life than would normally be expected. The importance of these neurological and respiratory problems later into adult life needs to be determined.

Abstract
First described more than 40 years ago, bronchopulmonary dysplasia (BPD) remains one of the most serious and vexing challenges in the care of very preterm infants. Affecting approximately one-quarter of infants born <1500g birth weight, BPD is associated with prolonged neonatal intensive care unit hospitalization, greater risk of neonatal and post-neonatal mortality and a host of associated medical and neurodevelopmental sequelae. This seminar focuses on the epidemiology and definition of BPD as well as the current evidence pertaining to a number of potential preventive treatments for BPD: non-invasive respiratory support technologies, inhaled nitric oxide, vitamin A, and caffeine.

Abstract
INTRODUCTION Extremely low gestational age newborns (ELGANs) are at increased risk of chronic lung disease (CLD) and of developmental delay. Some studies have suggested that CLD contributes to developmental delay. PATIENTS AND METHODS We examined data collected prospectively on 915 infants born before the 28th week of gestation in 2002-2004 who were assessed at 24 months of age with the Bayley Scales of Infant Development-2nd Edition or the Vineland Adaptive Behavior Scales. We excluded infants who were not able to walk independently (Gross Motor Function Classification System score < 1) and, therefore, more likely to have functionally important fine motor impairments. We defined CLD as receipt of oxygen at 36 weeks' postmenstrual age and classified infants as either not receiving mechanical ventilation (MV) (CLD without MV) or receiving MV (CLD with MV). RESULTS Forty-nine percent of ELGANs had CLD; of these, 14% were receiving MV at 36 weeks' postmenstrual age. ELGANs without CLD had the lowest risk of a Mental Developmental Index (MDI) or a Psychomotor Developmental Index (PDI) of <55, followed by ELGANs with CLD not receiving MV, and ELGANs with CLD receiving MV (9%, 12%, and 18% for the MDI and 7%, 10%, and 20% for the PDI, respectively). In time-oriented multivariate models, the risk of an MDI of <55 was associated with the following variables: gestational age of <25 weeks; single mother; late bacteremia; pneumothorax; and necrotizing enterocolitis. The risk of a PDI of <55 was associated with variables such as single mother, a complete course of antenatal corticosteroids, early and persistent pulmonary dysfunction, pulmonary deterioration during the second postnatal week, pneumothorax, and pulmonary interstitial emphysema. CLD, without or with MV, was not associated with the risk of either a low MDI or a low PDI. However, CLD with MV approached, but did not achieve, nominal statistical significance (odds ratio: 1.9 [95% confidence interval: 0.97-3.9]) for the association with a PDI of <55. CONCLUSIONS Among children without severe gross motor delays, risk factors for CLD account for the association between CLD and developmental delay. Once those factors are considered in time-oriented risk models, CLD does not seem to increase the risk of either a low MDI or a low PDI. However, severe CLD might increase the risk of a low PDI.

Abstract
OBJECTIVE The goal was to evaluate whether changes in neonatal intensive care have improved outcomes for children with bronchopulmonary dysplasia (oxygen dependence at corrected age of 36 weeks). METHODS We compared outcomes of extremely low birth weight (<1 kg) and extremely low gestational age (<28 weeks) infants with bronchopulmonary dysplasia between 2 periods (period I, 1996-1999: extremely low birth weight, n = 122; extremely low gestational age, n = 118; period II, 2000-2003: extremely low birth weight, n = 109; extremely low gestational age, n = 107). RESULTS For both groups, significant practice changes between period I and period II included increased prenatal and decreased postnatal steroid therapy and increased surfactant therapy, indomethacin therapy, and patent ductus arteriosus ligation. Significant morbidity changes included decreased rates of severe cranial ultrasound abnormalities and increased rates of ventilator dependence. Rates of bronchopulmonary dysplasia did not change (52% vs 53%). Follow-up evaluation revealed significantly lower rates of neurosensory abnormalities during period II (extremely low birth weight: 29% vs 16%; extremely low gestational age: 31% vs 16%). There were no changes in rates of Mental Developmental Index scores of <70 (extremely low birth weight: 42% vs 42%; extremely low gestational age: 37% vs 45%) or overall developmental impairment (extremely low birth weight: 51% vs 49%; extremely low gestational age: 50% vs 51%). For the extremely low gestational age group, predictors of neurosensory abnormalities were severe cranial ultrasound abnormality and postnatal steroid therapy. Predictors of overall impairment included severe cranial ultrasound abnormalities, ventilator dependence, postnatal steroid therapy, and patent ductus arteriosus ligation. For the extremely low birth weight group, the only predictor of neurosensory abnormalities was severe cranial ultrasound abnormality. Predictors of overall impairment included multiple birth, ventilator dependence, and severe cranial ultrasound abnormalities. CONCLUSIONS Neurosensory outcomes of infants with bronchopulmonary dysplasia improved during 2000 to 2003 but overall neurodevelopmental outcomes did not change.

Abstract
BACKGROUND There is little information available concerning behavioural and functional health problems in children who had bronchopulmonary dysplasia (BPD). AIM To compare behavioural problems and quality of life in a cohort of children at school age who had BPD with preterm and term controls. METHODS The cohort of 78 BPD children of 26 to 33 weeks' gestation was matched for birth weight with preterm controls. At school age follow-up, information was available for 66 BPD children and 60 preterm controls. (Three children with severe cerebral palsy were excluded). Parents completed the Child Behaviour Checklist (CBCL) and the Child Health Questionnaire (CHQ). The child's teacher completed the Teacher Report Form (TRF) of the CBCL, with the teachers of the BPD children completing a TRF on a classroom control. Parents completed a questionnaire on their levels of anxiety and depression. RESULTS The mean total problem score on the CBCL for the BPD children was similar to the controls, with the BPD children displaying more internalising behaviours. Little variation was seen between the BPD and preterm children on the TRF. Significant differences between classroom controls and the BPD children were found for the total problem scores (p=0.001), internalising behaviours (p=0.01) and social (p=0.047), attention (p=0.0001) and thought problems (0.047). Results from the CHQ showed no difference between the groups in their physical health or the impact of health problems on family life. CONCLUSION BPD children at school age display more internalising behaviour than preterm controls, with marked differences on comparison with classroom controls. Quality of life, however, does not seem to be adversely affected compared to the preterm controls.

Abstract
OBJECTIVE Preterm infants have reduced cerebral tissue volumes in adolescence. This study addresses the question: Is reduced global brain growth in the neonatal period inevitable after premature birth, or is it associated with specific medical risk factors? METHODS Eighty-nine preterm infants at term equivalent age without focal parenchymal brain lesions were studied with 20 full-term control infants. Using a deformation-based morphometric approach, we transformed images to a reference anatomic space, and we used the transformations to calculate whole-brain volume and ventricular volume for each subject. Patterns of volume difference were correlated with clinical data. RESULTS Cerebral volume is not reduced compared with term born control infants (p = 0.765). Supplemental oxygen requirement at 28 postnatal days is associated with lower cerebral tissue volume at term (p < 0.001), but there were no significant differences in cerebral volumes attributable to perinatal sepsis (p = 0.515) and quantitatively defined diffuse white matter injury (p = 0.183). As expected, the ventricular system is significantly larger in preterm infants at term equivalent age compared with term control infants (p < 0.001). INTERPRETATION Cerebral volume is not reduced during intensive care for the majority of preterm infants, but prolonged supplemental oxygen dependence is a risk factor for early attenuation of global brain growth. The reduced cerebral tissue volume seen in adolescents born preterm does not appear to be an inevitable association of prematurity, but rather caused by either specific disease during intensive care or factors operating beyond the neonatal period.

Abstract
OBJECTIVES Premature infants with chronic lung disease benefit from comprehensive care, which typically is based in tertiary medical centers. When such centers are not easily accessible, alternative models of care are needed. The purpose of this work was to compare community-based follow-up, provided via telephone contacts, to traditional center-based follow-up of premature infants with chronic lung disease. PATIENTS AND METHODS After discharge from neonatal intensive care, 150 premature infants with chronic lung disease were randomly assigned to either community-based (n = 75) or center-based (n = 75) follow-up. In community-based follow-up, a nurse specialist maintained telephone contact with the infant's primary caregiver and health care providers. Center-based follow-up consisted of visits to a medical center-based multidisciplinary clinic staffed by a neonatologist, a nurse specialist, and a social worker. The outcomes of interest were Bayley Scales of Infant Development mental developmental index and psychomotor developmental index, Vineland Adaptive Behavioral Composite, and growth delay (weight for length <5th percentile) at 1-year adjusted age and respiratory rehospitalizations through 1-year adjusted age. RESULTS In each randomization group, 73 infants survived, and 69 were evaluated at 1-year adjusted age. The median mental development index (corrected for gestational age) was 90 for both groups. The median psychomotor developmental index was 82 for the center-based group and 81 for the community-based group. The median Vineland Adaptive Behavioral Composite was 100 and 102 for the center-based and community-based groups, respectively. In the center-based and community-based groups, respectively, the proportions with growth delay were 13% and 26%, and the proportions rehospitalized for respiratory illness were 33% and 29%. CONCLUSIONS Infants randomly assigned to community-based, as compared with those randomly assigned to center-based follow-up, had similar developmental and health outcomes. The former approach might be a preferred alternative for families in rural settings or families for whom access to a tertiary care medical center is difficult.

Abstract
Approximately 25% to 30% of all complaints to a general pediatrician are developmental or behavioral in origin. Despite this, residency education in developmental/behavioral pediatrics has consistently been rated poorly. Changes were set forth in 1997 to include a mandatory 1-month block rotation in developmental/behavioral pediatrics. This study was a nationwide, cross-sectional, self-administered, mailed survey of pediatricians who completed residency either before or after these changes went into effect. Overall, pediatricians' comfort level in developmental/behavioral pediatrics was unchanged in the 2 groups. Certain areas (behavior problems, learning disabilities, sleep, and depression/anxiety) of developmental/behavioral pediatrics had lower comfort scores. Our data provide direction for the ongoing refinement of pediatric education that is based on feedback from currently practicing pediatricians.

Abstract
OBJECTIVES Premature and low birth weight children have a high prevalence of academic difficulties. This study examines a model comprised of cumulative risk factors that allows early identification of these difficulties. METHODS This is a secondary analysis of data from a large cohort of premature (<37 weeks gestation) and LBW (<2500 g) children. The study subjects were 8 years of age and 494 had data available for reading achievement and 469 for mathematics. Potential predictor variables were categorized into 4 domains: sociodemographic, neonatal, maternal mental health and early childhood (ages 3 and 5). Regression analysis was used to create a model to predict reading and mathematics scores. RESULTS Variables from all domains were significant in the model, predicting low achievement scores in reading (R (2) of 0.49, model p-value < .0001) and mathematics (R (2) of 0.44, model p-value < .0001). Significant risk factors for lower reading scores, were: lower maternal education and income, and Black or Hispanic race (sociodemographic); lower birth weight and male gender (neonatal); lower maternal responsivity (maternal mental health); lower intelligence, visual-motor skill and higher behavioral disturbance scores (early childhood). Lower mathematics scores were predicted by lower maternal education, income and age and Black or Hispanic race (sociodemographic); lower birth weight and higher head circumference (neonatal); lower maternal responsivity (maternal mental health); lower intelligence, visual-motor skill and higher behavioral disturbance scores (early childhood). CONCLUSIONS Sequential early childhood risk factors in premature and LBW children lead to a cumulative risk for academic difficulties and can be used for early identification.

Abstract
Children born very preterm are vulnerable for long-term cognitive, educational, and behavioral impairments; bronchopulmonary dysplasia (BPD) is an additional risk factor which exacerbates these problems. As a population, children with BPD exhibit low average IQ, academic difficulties, delayed speech and language development, visual-motor integration impairments, and behavior problems. Neuropsychological studies are sparse, but there is some evidence that children with BPD also display attention problems, memory and learning deficits, and executive dysfunction. BPD does not appear to be associated with a specific neuropsychological impairment but rather a global impairment.

Abstract
This study describes the vocal development of infants born with very low birth weights (VLBW). Samples of vocalizations were recorded from three groups of infants when they were 8, 12 and 18 months of age: preterm VLBW infants with bronchopulmonary dysplasia (BPD), preterm VLBW infants without BPD, and healthy full-term infants. Infants with BPD produced significantly smaller canonical syllable ratios than the full-term infants throughout the period of study. Premature VLBW infants who did not suffer from BPD produced relatively little canonical babble at 8 months of age, but were performing within the range of the full-term infants at 18 months of age. At 18 months of age, the infants with BPD were reported to have significantly smaller expressive vocabulary sizes than the healthier preterm and full-term infants.

Abstract
OBJECTIVE To investigate the cognitive performance and educational attainment at school-age of children with bronchopulmonary dysplasia (BPD), compared with a preterm control group of children. METHODS Seventy preterm infants with BPD and 61 birth weight matched controls were prospectively followed-up to school-age. The Weschler Intelligence Scale for Children - III (WISC), the Wide Range Achievement Test (WRAT) and the Developmental Test of Visual Motor Integration (VMI) were administered. The results were compared between the two groups and multiple regression analyses were performed to determine the effect of confounding variables. RESULTS The children in the BPD group performed less well on the Full Scale IQ (mean 86.7 vs 93.5; 95% CI, 1.9-11.7), Verbal IQ (mean 87.1 vs 94.1; 95% CI, 2.0-12.0) and the Performance IQ (mean 88.6 vs 95.2; 95% CI, 2.0-11.2) of the WISC, the reading component of the WRAT (mean 93.8 vs 98.9; 95% CI, 0.3-9.8) and the VMI (mean 88.9 vs 93.3; 95%, CI 1.1-7.8). Despite controlling for social and biological variables, statistical differences persisted for Full Scale and Verbal IQ and reading. A Verbal IQ >1 SD below the mean was found in 41% of BPD children compared to 21% of controls, while on the reading component of the WRAT a greater proportion of BPD children also had scores>1 SD below the mean. CONCLUSION Impaired psychoeducational performance was found in preterm children with BPD compared to controls, especially in the areas of language abilities and reading skills. This supports a greater need for special educational services and counseling for parents for these children.

Abstract
OBJECTIVE To examine the effects of bronchopulmonary dysplasia (BPD) and very low birth weight (VLBW) on the cognitive and academic achievement of a large sample of 8-year-old children. METHODS Infants who were VLBW and had BPD (n = 98) or did not have BPD (n = 75) and term infants (n = 99) were followed prospectively to age 8. Groups were compared on measures assessing 4 broad areas of functioning: intelligence, achievement, gross motor, and attentional skills. Measures included the Wechsler Intelligence Scale for Children III, the Woodcock Johnson Test of Achievement-Revised, the Bruininks-Oseretsky Test of Motor Proficiency, the Tactual Performance Test (spatial memory), and the Continuous Performance Test (attention). School outcomes were assessed by parent and teacher report, as well as from school records. Groups were comparable on socioeconomic status, sex, and race. The total sample of BPD, VLBW, and term children was compared on all outcome measures. In addition, neurologic risk was assessed in the present sample and included the following: intraventricular hemorrhage, echodense lesions, porencephaly, hydrocephalus, ventriculoperitoneal shunt, meningitis, and periventricular leukomalacia. Individual difference analyses were conducted for neurologically intact children in all 3 groups. Finally, treatment effects were examined by comparing BPD children who had received steroids as part of their treatment with BPD children who had not. RESULTS The BPD group demonstrated deficits compared with VLBW and term children in intelligence; reading, mathematics, and gross motor skills; and special education services. VLBW children differed from term children in all of the above areas, except reading recognition, comprehension, and occupational therapy. Attentional differences were obtained between BPD and term children only. The BPD group (54%) was more likely to be enrolled in special education classes than VLBW (37%) or term children (25%). In addition, more BPD children (20%) achieved full-scale IQ scores <70, in the mental retardation range, compared with either VLBW (11%) or term (3%) children, with all VLBW children significantly more likely than term children to achieve IQs in the subaverage category. After controlling for birth weight and neurologic problems, BPD and/or duration on oxygen predicted lower performance IQ, perceptual organization, full-scale IQ, motor and attentional skills, and special education placement. The qualitative classification of BPD (present or absent) was a significant predictor for lower scores on measures of applied problems; motor skills; and incidence of speech-language, occupational, and physical therapies. Individual difference analyses were performed to ascertain whether differences between the risk groups were primarily attributable to neurologic complications. Even with the neurologically intact sample of BPD and VLBW children, differences between the term comparison group and both the BPD and VLBW groups were found for many outcome measures. When birth weight and neurologic complications were controlled, BPD and severity of BPD were associated with lower performance and full-scale IQ, poorer perceptual organization, attention, and motor skills, as well as lower school achievement and greater participation in special education, including occupational, physical, and speech-language therapies. Treatment protocol may in part be responsible for differences observed in our BPD sample. Steroid and nonsteroid groups of BPD children differed significantly in performance IQ (72.8 vs 84.8) and full-scale IQ (77.0 vs 85.2); perceptual organization (74.0 vs 85.2); Bruininks-Oseretsky Test of Motor Proficiency score (36.6 vs 44.7); and participation in special education (78% vs 48%), occupational therapy (71% vs 44%), and physical therapy (71% vs 41%). In every instance, BPD children who received steroids fared more poorly than BPD children who did not receive steroids. CONCLUSIONS BPD and duration on oxygen have long-term adverse effects on cognitive and academic achievement above and be beyond the effects of VLBW. The problems that have been identified at 8 years of age highlight the need for continued monitoring of the learning, behavior, and development of BPD children to intervene with children who are at risk for school problems.

Abstract
The purposes of this study were (1) to evaluate the usefulness of the Neonatal Behavioral Assessment Scale (NBAS) as a tool to assess the risk of later behavioral problems, (2) to analyze the relationship between neonatal behavioral characteristics and behavioral problems in childhood. Subjects were 77 very-low-birth-weight infants admitted to the NICU at the Nagasaki University Hospital, Nagasaki, Japan. The results suggest that behavioral characteristics such as poor motor performance, poor state regulation, and poor interaction ability in the neonatal period are risk factors for behavioral problems in childhood. The NBAS could help clinicians to identify neonates at risk of later behavioral problems.

Abstract
OBJECTIVE Low superior vena cava (SVC) flow is common in very preterm infants in the first day and strongly associated with periventricular hemorrhage and disability. We examined the effect of high-frequency oscillatory ventilation (HFOV) compared with conventional ventilation (CV) on SVC flow and right ventricular output. METHODS Forty-five infants <29 weeks were randomized before 1 hour of age to HFOV or CV. Echocardiography was performed on 43 infants at 3, 10, and 24 hours of age. Infants with low SVC flow (<50 mL/kg/min) or hypotension (mean blood pressure < or =20) were treated with volume and inotrope. RESULTS Infants allocated to HFOV (n=23) and to CV (n=20) were well matched. There was a nonsignificant trend toward more infants on HFOV having SVC flow <50 mL/kg/min (48% vs 20%) and receiving volume and inotropes (61% vs 40%). There were no significant differences in mean SVC flow or right ventricular output at 3, 10, or 24 hours. Infants on HFOV had a significantly higher calculated upper body vascular resistance at 10 hours and mean blood pressure at 24 hours. CONCLUSIONS There were no significant adverse effects of HFOV on systemic blood flow in very preterm infants during the first 24 hours of life.

Abstract
UNLABELLED A prospective follow-up of very low birth weight infants (VLBW) with (n = 89) and without (n = 71) bronchopulmonary dysplasia (BPD) and Term control children (n = 93) was conducted at 8 years of age. Groups were compared on measures of articulation, receptive and expressive language, verbal and performance IQ, oral motor skills and gross and fine motor skills. The BPD group demonstrated reduced articulation, receptive language skills, performance IQ, and overall gross and fine motor skills when compared to VLBW and Term groups. The BPD and VLBW groups did not differ on expressive language, oral motor skills, or verbal IQ. The groups also differed in enrollment in special classes and speech-language therapy, with almost half (48%) of the BPD group enrolled in speech-language therapy compared to 21% of the VLBW group, and 9% of the Term group. These results suggest that BPD may have adverse effects on speech development as well as on performance IQ, motor skills, and receptive language over and above the effects of VLBW. LEARNING OUTCOMES (1) As a result of this activity the reader will be able to describe what BPD is and how it impacts speech and language. (2) As a result of this activity the reader will be able to discuss how children with VLBW with BPD differ from children with VLBW without BPD in their developmental outcomes.

Abstract
OBJECTIVE To compare school performance at age 10 years in a cohort of extremely preterm children and term control subjects and to examine the impact of family composition and stability on performance. STUDY DESIGN Prospective, longitudinal follow-up from birth to 10 years of age of a regional cohort of children born at 24 to 31 weeks of gestational age and sociodemographically matched term control subjects. Family composition, extent of parental care giving, and family moves were tracked sequentially. At 10 years, academic achievement and school performance were ascertained for 118 of 125 (94%) preterm survivors and 119 of 125 (95%) term children. RESULTS Term children were more likely to demonstrate optimal school outcome (appropriate grade level without additional classroom assistance) than were preterm children (odds ratio 3.4, 95% CI 1.9-6.0). Medical complications related to prematurity had little impact on school outcome. Among preterm children, optimal school outcome was significantly associated with increased parental education, child rearing by 2 parents (regardless of marital status), and stability in family composition and geographic residence over 10 years. These environmental influences were less pronounced among term control subjects. CONCLUSION Although preterm children performed less well in school than term children, family factors were stronger predictors of school performance than were perinatal complications.
