Single Center Outcome of Multiple Births in the Premature and Very Low Birth Weight Cohort in Singapore.

OBJECTIVE: The aim of this study is to compare neonatal mortality and morbidity in multiple and singleton preterm/very low birthweight (PT/VLBW) multiethnic Asian infants. STUDY DESIGN: Cohort study of 676 singleton and 299 multiple PT/VLBW infants born between 2008 and 2012 at KK Women's and Children's Hospital, the largest tertiary perinatal center in Singapore with further stratification by gestational ages 23 to 25 (Group 1), 26 to 28 (Group 2), and ≥29 (Group 3) weeks. Outcome measures included predischarge mortality and major neonatal morbidity. RESULTS: Overall survival to discharge was comparable for singletons 611/676 (90%) and multiples 273/299 (91%). Use of assisted reproductive technologies (47 vs. 4%), antenatal steroids (80 vs. 68%), and delivery by cesarean section (84 vs. 62%) were significantly higher (p < 0.001) in multiples while pregnancy induced hypertension (8.7 vs. 31.6%, p < 0.001) and maternal chorioamnionitis (31 vs. 41%, p < 0.01) were seen less commonly compared with singleton pregnancies. Survival was comparable between singletons and multiples except for a lower survival in multiples in Group 2 (81.7 vs. 92.4%, p = 0.007). Major neonatal morbidities were comparable for multiples and singletons in the overall cohort. Presence of hemodynamically significant patent ductus arteriosus (HsPDA) requiring treatment (88.9 vs. 72.5%), air leaks (33 vs. 14.6%, p = 0.02), NEC (30 vs. 14.6%, p = 0.04), and composite morbidity (86 vs. 66%, p = 0.031) were significantly higher in multiples in Group 1. A significantly higher incidence of HsPDA (68.1 vs. 52.4%, p = 0.008) was also observed in multiples in Group 2. Multiple pregnancy was not an independent predictor of an adverse outcome on regression analysis (OR: 0.685, 95% confidence interval: 0.629-2.02) even in GA ≤25 weeks. CONCLUSION: Neonatal mortality and morbidity were comparable in our cohort of PT/VLBW singletons and multiple births, but preterm multiple births ≤25 weeks had a higher incidence of neonatal morbidity. KEY POINTS: · Use of assisted reproductive technologies was significantly higher in multiples as compared to singletons.. · Major neonatal morbidities and mortality were similar between singletons and multiples in our cohort.. · In gestations less than 25 weeks multiples had higher neonatal morbidities than their singleton counterparts..

Prospective evaluation of the Ages and Stages Questionnaire 3rd Edition in very-low-birthweight infants.

AIM: To evaluate the predictive and concurrent diagnostic agreement of the Ages and Stages Questionnaire 3rd Edition (ASQ-3) with the Bayley Scales of Infant and Toddler Development 3rd Edition (Bayley-III) in infants born preterm and very-low-birthweight (PT/VLBW; ≤1250g). METHOD: We evaluated 141 PT/VLBW infants (68 males, 73 females) born at the KK Women's and Children's Hospital between January 2010 and December 2011, to determine predictive and concurrent diagnostic agreement between the ASQ-3 at 9, 12, 18, and 24 months corrected age and Bayley-III at 24 months. Cut-offs on the ASQ-3 at 24 months were estimated by receiver operating characteristic curves. RESULTS: Sixty (43%) and 25 (18%) failed in any domain of the ASQ-3 and Bayley-III (<70) respectively. A negative predictive value (NPV) >98% was achieved for the motor domain from 9 months, and >90% for the communication domain and the overall results at 24 months. Optimal referral ASQ-3 score at 24 months to achieve 100% NPV was 243. INTERPRETATION: In PT/VLBW infants, ASQ-3 screening at 24 months can reduce the need for costly psychometric assessments in children with normal results. Clinicians can be assured of normal motor development at 9 months using the ASQ-3, but should continue to screen children on other domains.

Nutritional intake and growth velocity in preterm extremely low-birthweight infants in Asia: Are we doing enough?

AIM: To describe nutritional practices among preterm extremely low-birthweight (ELBW) infants and their impact on growth and to compare differences in nutritional intervention and comorbidities between those with limited growth velocity (GV < 25th percentile) and those with GV > 25th percentile. METHODS: A prospective cohort study was conducted to assess total protein and energy intake for week 1, days 14, 21 and 28 of life. Post-natal growth was calculated by measuring GV using an exponential model. Univariable analysis was applied to identify the potential risk factors associated with poor GV at day 28 and at discharge from hospital. RESULTS: The median GV from birth to day 28 was 9.84 g/kg/day and 11.87 g/kg/day for GV from birth to discharge. Increased protein and energy intake was associated with higher GV at discharge. Hypotension needing inotropes, necrotising enterocolitis (NEC), patent ductus arteriosus and chronic lung disease were significantly associated with reduced GV at discharge. Infants with NEC, hypotension needing inotropes and sepsis took a significantly longer time to achieve full enteral nutrition. A longer time to attain full enteral feeds was associated with slower GV at discharge. Small-for-gestational-age babies increased from 22% at birth to 66.6% at discharge. CONCLUSIONS: GV at discharge was positively correlated with increasing protein and energy intake in the first 28 days and adversely affected by the presence of neonatal morbidities. There was strong evidence of extra-uterine growth restriction, with the majority of preterm ELBW infants having lower z scores at discharge compared to at birth.

A quality improvement project to reduce hypothermia in preterm infants on admission to the neonatal intensive care unit.

OBJECTIVE: To study effectiveness of quality improvement interventions in reducing hypothermia in preterm infants on admission to neonatal intensive care unit. DESIGN: Quality improvement methodologies including multidisciplinary planning and implementation of evidence-based interventions. Data during and post-implementation were collected. SETTING AND PARTICIPANTS: In total, 84 preterm infants with birth weights ≤ 1500 g delivered during implementation period (October 2008-April 2009) were compared with 168 historical controls and 947 infants in the subsequent 4 years. INTERVENTION(S): In addition to routine interventions, delivery room temperatures were increased, and use of full-body polyethylene wraps and woollen caps were implemented during initial stabilization. Education and training were provided to reinforce the new interventions. MAIN OUTCOME MEASURE(S): Primary outcome was incidence of hypothermia and mean admission temperature. Secondary outcomes were rates of intraventricular haemorrhage and mortality. RESULTS: Incidence of admission hypothermia decreased from 79.4 to 40.5% (P < 0.001), constituting a 49% improvement (OR = 0.177, 95% CI: 0.099-0.316). Mean admission temperature increased from 35.8 ± 0.8°C to 36.5 ± 0.7°C (P < 0.001). Hyperthermia incidence was higher at 6% compared to baseline of 1.3% (P = 0.049). The incidence of admission hypothermia remained stable at 47.4% in the 4 years post-implementation. Rates of intraventricular haemorrhage and mortality remained unchanged. Small for gestation, low 5-min Apgar score and singleton delivery were factors found to be associated with admission hypothermia. CONCLUSION: The implementation of evidence-based best practices resulted in significant reduction in admission hypothermia in preterm infants, which persisted for 4 years post-implementation. The practices have since become standard of care in our institution.

Back to basics: a bilingual advantage in infant visual habituation.

Comparisons of cognitive processing in monolinguals and bilinguals have revealed a bilingual advantage in inhibitory control. Recent studies have demonstrated advantages associated with exposure to two languages in infancy. However, the domain specificity and scope of the infant bilingual advantage in infancy remains unclear. In the present study, 114 monolingual and bilingual infants were compared in a very basic task of information processing-visual habituation-at 6 months of age. Bilingual infants demonstrated greater efficiency in stimulus encoding as well as in improved recognition memory for familiar stimuli as compared to monolinguals. Findings reveal a generalized cognitive advantage in bilingual infants that is broad in scope, early to emerge, and not specific to language.

Concurrent validity of the ages and stages questionnaires with Bayley Scales of Infant Development-III at 2 years - Singapore cohort study.

BACKGROUND: With increasing acceptance of universal developmental screening in primary care, it is essential to evaluate the local validity and psychometric properties of commonly used questionnaires like the parent-completed Ages and Stages Questionnaires, 3rd Edition (ASQ-3) in identifying developmental delays. The aim of this study is to assess the convergent validity of the ASQ-3 with the Bayley Scales of Infant Development-3rd edition (Bayley-III) in identifying developmental delay in a low-risk term cohort in Singapore. METHODS: ASQ-3 and Bayley-III data was collected prospectively with generation of ASQ-3 cut-off scores using three different criteria: 1-standard deviation (SD) (Criterion-I) or 2-SD (Criterion-II) below the mean, and using a Receiver Operator Curve (ROC) (Criterion-III). Sensitivity, specificity, positive (PPV) and negative (NPV) predictive values were calculated. Correlations between the ASQ-3 and Bayley-III domains were evaluated using Pearson coefficients. RESULTS: With all three criteria across different domains ASQ-3 showed high specificity (72-99%) and NPV (69-98%), but lower sensitivity (19-74%) and PPV (11-59%). Criterion-I identified 11-21% of children as "at-risk of developmental delay," and was the most promising criterion measure, with high specificity (82-91%), NPV (69-74%) and overall agreement of 64-71%. Moderate-strong correlations were seen between ASQ-3 Communication and Bayley-III Language scales (r = 0.44-0.59, p < 0.01). The lowest sensitivities were seen in the motor domains. CONCLUSIONS: ASQ-3 is reliable in low-risk settings in identifying typically developing children not at risk of developmental delay, but it has modest sensitivity. Moderate-strong correlations seen in the communication domain are clinically important for early identification of language delay, which is one of the most prevalent areas of early childhood developmental delay.

Impact of family and caregiver factors on development and behaviours in maltreated young children.

Introduction: This study aimed to evaluate the prevalence of developmental and emotional/ behavioural concerns in maltreated children and to examine the impact of adverse family/caregiver risk factors on these outcomes. Method: We analysed family demographic and baseline data of 132 maltreated children and their caregivers from a family support programme in Singapore. We examined the associations of 3 main risk factors (i.e., caregiver mental health, educational attainment, and family socio-economic status [SES]) with developmental/behavioural outcomes using multivariable logistic regression, controlling for caregiver relationship to the child. Caregiver mental health was assessed using the Patient Health Questionnaire 9 (PHQ-9) and General Anxiety Disorder 7 (GAD-7) tools. Developmental/behavioural outcomes were assessed using the Ages and Stages Questionnaires (ASQ-3), ASQ-Social-Emotional (ASQ-SE), and the Child Behaviour Checklist (CBCL). Results: The children ranged in age, from 2 months to 3 years 11 months (median age 1.7 years, interquartile range [IQR] 0.9-2.6). Among caregivers, 86 (65.2%) were biological mothers, 11 (8.3%) were biological fathers, and 35 (26.5%) were foster parents or extended family members. Low family SES was associated with communication concerns on the ASQ-3 (adjusted odds ratio [AOR] 3.04, 95% CI 1.08-8.57, P=0.04). Caregiver mental health concerns were associated with increased behavioural concerns on the CBCL (AOR 6.54, 95% CI 1.83-23.33, P=0.004) and higher scores on the ASQ-SE (AOR 7.78, 95% CI 2.38-25.38, P=0.001). Conclusion: Maltreated children with caregivers experiencing mental health issues are more likely to have heightened emotional and behavioural concerns. Those from low SES families are also at increased risk of language delay, affecting their communication.

Exploring the validity of the ASQ-SE for socio-emotional competency screening of a low-risk Asian cohort at 2 years of age.

AIMS: To assess the Ages & Stages Questionnaire: Social-Emotional (ASQ-SE)'s concurrent validity in a low-risk Singapore cohort and study its association with maternal mental health status. METHODS: Concurrent validity of the parent-filled ASQ-SE with Child Behavior Checklist (CBCL1.5-5) was evaluated in 341 children at age 24 months. Data on maternal anxiety and depression were collected using the State-Trait Anxiety Inventory (STAI) and Beck Depression Inventory-Second Version (BDI-II). ASQ-SE cut-off scores based on receiver operating characteristic curve were compared to CBCL scores to derive a local ASQ-SE "at risk" cut-off score. Correlations of ASQ-SE with CBCL scores and with maternal STAI and BDI scores were evaluated using Pearson coefficients. RESULTS: Using a cut-off score of 51 at 24 months, ASQ-SE had acceptable concurrent validity, with an AUC of 0.819(0.765-0.872), 70 % sensitivity and 79 % specificity. Mothers of children with "at-risk" ASQ-SE scores had significantly higher STAI and BDI-II scores. ASQ-SE had moderate- high correlations (r = 0.32-0.53) (p < .01) with CBCL scores at 24 and 48 months and with maternal mental health status(r = 0.32). INTERPRETATION: ASQ-SE can be a useful tool for screening child's socio-emotional competence for primary health care use in Singapore Dyadic mental health screening would be helpful in identifying families at risk.

Risk Factors Predicting the Need for Phototherapy in Glucose 6 Phosphate Dehydrogenase-Deficient Infants in a Large Retrospective Cohort Study.

INTRODUCTION: Glucose 6-phosphate dehydrogenase (G6PD) deficiency increases the risk of severe neonatal hyperbilirubinemia. This study evaluates the risk factors predicting the need for phototherapy in G6PD-deficient neonates after 72 h of age and assesses the safety of early discharge. METHODS: A retrospective cohort study of 681 full-term G6PD-deficient infants with a birth weight ≥2,500 g over 4 years was conducted. We compared the baseline characteristics, bilirubin level on day 4 (after 72 h of life), day of peak bilirubin, G6PD levels, and concomitant ABO incompatibility between the group that required phototherapy (Group A) and those who did not (Group B). RESULTS: 396 infants (58%), predominantly males, required phototherapy in the first week of life. The infants who required phototherapy had a lower median gestational age (38.3 vs. 38.7 weeks, p < 0.01) and had lower G6PD levels (2.3 ± 2.5 vs. 3 ± 3.4 IU, p < 0.05) compared to the controls. The mean day-four total serum bilirubin (TSB) levels were higher (213 ± 32 vs. 151 ± 37 µmol/L, p < 0.01), with bilirubin level peaking earlier (3 vs. 4 days of life, p < 0.01) in group A. Regression analysis identified TSB levels on day 4, Chinese race, lower gestation, and concomitant ABO incompatibility as the significant predictors for the need for phototherapy in the study population. In particular, coexisting ABO blood group incompatibility increased the risk of jaundice requiring phototherapy (OR 4.27, 95% CI: 1.98-121, p < 0.01). Day four TSB values above 180 µmol/L predicted the need for phototherapy with 86% sensitivity and 80% specificity. The findings were similar across both male and female infants with G6PD deficiency. CONCLUSION: G6PD-deficient infants with day four TSB levels of >180 µmol/L (10.5 mg/dL) and associated ABO blood group incompatibility have a higher risk of requiring phototherapy in the first week of life and should be closely monitored.

Agro-industrial-residues as potting media: physicochemical and biological characters and their influence on plant growth.

Nursery cultivation is recognized globally as an intensive production system to support quality seedlings as well as to manage resources efficiently. Apart from other factors, potting media (PM) play a crucial role in determining the success of nursery cultivation. Worldwide, peat is the most commonly used substrate in PM because of its favorable physicochemical properties. However, due to ascending environmental and ecological concerns regarding the use of peat, a variety of new substrates have been used/tested by researchers/practitioners/growers as PM. Bark, coir pith, wood fiber, compost derived from various agro-residues, and vermicompost either alone or in combination are some of the commonly explored substrates and found to have the potential to replace peat to a greater extent. In lieu of availability, abundance, low cost, and no/low processing requirement, the use of agro-industrial residue (AIR) in the PM is the current trend. However, challenges associated with their adoption cannot be ignored. The present review is focused on providing collective information, scientific knowledge and detailed analysis of various AIR used in PM. The critical evidence-based review would help in developing a consistent approach for the identification, selection and characterization of a new renewable substrate. In addition, it would help in developing a rationale understanding of the practical and economic realities involved in the adoption of the same in PM.

New BPD-prevalence and risk factors for bronchopulmonary dysplasia/mortality in extremely low gestational age infants ≤28 weeks.

OBJECTIVE: To evaluate prevalence and risk factors of moderate-severe Bronchopulmonary dysplasia (BPD)/Death in extremely low gestation age neonates (ELGANs). STUDY DESIGN: Study of 266 ELGANs born at gestational age (GA) ≤ 28 weeks (w). Primary Outcome measure-composite outcome of moderate-severe BPD/Death using the National Institute of Child Health and Human Development NICHD's (2001) BPD definition. RESULT: Cohort's mean GA and birth-weight (BW) were 25.3 ± 1.4w and 724 ± 14 g respectively with an overall mortality of 19% and moderate-severe BPD of 67%. Prevalence of moderate-severe BPD/death decreased significantly with increasing GA (86-93%) at 23-24 w; to <60% at 27-28w (OR 0.63; 95% CI; 0.52-0.77). On univariate analysis, other risk factors included BW(OR 1.005; 95% CI; 1.003-1.007), Sepsis (OR 2.9; 95% CI, 1.3-6.4), PDA needing treatment (OR 2.2; 95% CI, 1.3-3.9); air leaks (OR 2.7; 95% CI; 1.02-7.3) FiO2 requirement >25%(OR 1.06; 95% CI; 1.01-1.11); and mechanical ventilation(MV) on Day7 (OR5.5; 95% CI; 2.8-10.8). Only need for Day7 MV was independently predictive of composite outcome (OR1.97; 95% CI; 1.3-3.1). CONCLUSION: Risk factor identification will enable initiatives to implement lung protective strategies and develop prospective models for BPD prediction and prognostication.

Academic school readiness in children born very preterm and associated risk factors.

BACKGROUND AND AIMS: Although the intelligence quotient (IQ) test is useful to assess general cognitive function, it may miss more specific and subtle deficits of learning, working memory, attention and executive function. This study aims to evaluate cognitive performance and academic school readiness (SR) concepts in preterm very low birth weight (PT/VLBW) children, compared to typically developing term controls and to evaluate factors affecting basic (SR) concepts in children with IQ>85. METHODS: A prospective cohort study of 123 PT/VLBW survivors with birth weights ≤1250 g and 74 term controls born between 2007 and 2009 in Singapore were assessed for school readiness using Wechsler Preschool and Primary Scale of Intelligence (WPPSI-III), Bracken School Readiness Assessment (BSRA-3) and Beery-Buktenica Developmental Test of Visual Motor Integration (VMI) at age 5.5 years. Social risk composite score (SRCS) was calculated based on ethnicity, parental education and family income and marital status. Uni- and multi-variable regressions were conducted to evaluate risk factors associated with poor academic SR in the entire cohort and in those with IQ >85. RESULTS: Mean gestational age and birth weight of the 123 PT/VLBW children were 27.8 (2.3) weeks and 939 (194) grams while that of the 74 term controls were 38.8 (1.2) weeks and 3165 (402) grams. PT/VLBW survivors had statistically significant lower full composite scores on WPPSI-III (97.0 vs 114), BSRA-3 (98.5 vs 112.3) and VMI (107.2 vs 112.9) compared to controls. The differences remained significant in preterm and children with higher SRCS even after adjustment. CONCLUSIONS: Prematurity and high social composite risk scores were risk factors affecting academic SR and this difference persisted in PT/VLBW children with normal cognitive scores with IQ >85.

The Test of Infant Motor Performance (TIMP) in very low birth weight infants and outcome at two years of age.

OBJECTIVE: To evaluate TIMP in preterm very low birth weight (VLBW) infants, analyze risk factors, for atypical TIMP (aTIMP) scores, and explore TIMP's predictive relationship with Bayley-III at 2 years. METHOD: A prospective study of 288 VLBW infants, with TIMP assessment between 34 weeks postmenstrual age and 16 weeks age, corrected for prematurity. RESULT: aTIMP scores were observed in 58/288(20%) infants, whose mean birth weight (BW) and gestational age were 1122 ± 257 g and 29.2 ± 2.12 weeks respectively. Risk factors included BW < 750 g (OR 4.8, 95% CI 1.3-17.7) and 750-1000 g (OR 2.9, 95% CI 1.2-6.9), presence of necrotizing enterocolitis ≥ stage 2; or focal intestinal perforation (OR 4.6, 95% CI 1.4-14.4), periventricular leukomalacia (OR 22.4,95% CI 2.0-246.2), and need for intensive resuscitation at birth (OR 2.7, 95% CI 1.3-5.5). aTIMP scores correlated with Bayley-III Score <85 in motor and cognitive domains with high specificity (80-82%) and negative predictive value (85-94%). CONCLUSION: Identification of the risk factors for aTIMP scores will enable targeted intervention to optimize resources and outcomes in VLBW infants.

Novel two-tiered developmental screening programme for Singaporean toddlers: a quality improvement report.

Early identification of developmental delays with timely intervention, especially before the age of 3 years, can improve child development. In Singapore, however, diagnosis and intervention for developmental delays occur at a median age of 44 months. As early detection and intervention depends on an effective developmental screening programme, we aimed to improve the detection of developmental delays before the age of 3 years in a primary care setting. We did this by implementing a novel two-tiered screening programme which uses three standardised screening tools (Parents' Evaluation of Developmental Status, PEDS-Developmental Milestones and Ages and Stages Questionnaire-3). We used quality improvement methods to integrate and optimise this two-tiered programme into the existing 9-month and 18-month screening schedule, with an additional screening at 30 months to replace the pre-existing 36-month screening of the National Child Health Surveillance Programme. A total of three Plan-Do-Study-Act cycles were performed to ensure programme feasibility and sustainability. They focused on adequately training the primary care nurses, targeting an 80% screening rate and aiming for 20 min screening tool administration time per child. We assessed the proportion of children referred to the child development units after positive screening for developmental concerns under the new programme, with a pre-post and with-without intervention comparison, and reviewed the screening rates and screening tool administration time. The proportion of 18-month old children referred for developmental concerns improved from 3.5%-7.1% over a 6-month period. For those who received further assessment by developmental specialists after the two-tiered screening, 100% received a definitive diagnosis of developmental delays, similar to the situation before programme introduction. Our quality improvement efforts facilitated successful integration of the two-tiered programme into the pre-existing screening schedule with minimal impact to the clinic workflow. While we highlight challenges in implementation that need to be addressed, our findings support a potential nationwide adoption of the two-tiered programme.

Evaluation of the Ages and Stages Questionnaire (ASQ 3) as a developmental screener at 9, 18, and 24 months.

BACKGROUND: Without the use of standardized screening tools, only 30% of the estimated 5-15% of children with developmental delay can be identified, potentially delaying intervention. AIM: 1)To evaluate the ASQ-3's reliability and validity at 9, 18, and 24 months and to compare the results with normative USA data. 2)To determine the risk factors for a screen positive result, which requires further evaluation. METHODS: Study of 649 low-risk children was part of a larger longitudinal cohort study, the GUSTO project. Socio-demographic and ASQ3 data were analyzed to estimate reliability, validity, mean ASQ scores, and cut-off scores. RESULTS: ASQ-3 showed an acceptable to good internal consistency (0.49-0.83) and a medium level of correlations (0.22-0.59) between the five domains but differed significantly compared to normative USA data. Using local cut-off scores, 12.6-13.6% of the cohort had a positive screen in ≥ 1 domain at 9, 18, or 24 months. ASQ-3 screening categorization was consistent, with only 3-11% of children showing change in categorization longitudinally. On regression, lower family income (OR 3.3-9.42) and maternal education (OR2.65-3.03) were predictive of a positive screen across domains and age intervals. INTERPRETATION: ASQ-3 is a useful, valid screening tool in Singapore. Further research is needed to investigate item functioning and to assess its concurrent validity with a criterion standard tool for culturally sensitive developmental screening.

Developmental delay: identification and management at primary care level.

Developmental delays are common in childhood, occurring in 10%-15% of preschool children. Global developmental delays are less common, occurring in 1%-3% of preschool children. Developmental delays are identified during routine checks by the primary care physician or when the parent or preschool raises concerns. Assessment for developmental delay in primary care settings should include a general and systemic examination, including plotting growth centiles, hearing and vision assessment, baseline blood tests if deemed necessary, referral to a developmental paediatrician, and counselling the parents. It is important to follow up with the parents at the earliest opportunity to ensure that the referral has been activated. For children with mild developmental delays, in the absence of any red flags for development and no abnormal findings on clinical examination, advice on appropriate stimulation activities can be provided and a review conducted in three months' time.

Developmental assessment: practice tips for primary care physicians.

Child development refers to the continuous but predictably sequential biological, psychological and emotional changes that occur in human beings between birth and the end of adolescence. Developmental surveillance should be incorporated into every child visit. Parents play an important role in the child's developmental assessment. The primary care physician should educate and encourage parents to use the developmental checklist in the health booklet to monitor their child's development. Further evaluation is necessary when developmental delay is identified. This article aimed to highlight the normal child developmental assessment as well as to provide suggestions for screening tools and questions to be used within the primary care setting.

An epidemiologic study comparing fetal exposure to tobacco smoke in three Southeast Asian countries.

The high prevalence of smoking in Southeast Asia (SEA) means pregnant women face exposure to tobacco smoke that may affect the health of their fetus. This study determined fetal exposure to tobacco smoke by meconium analysis for cotinine in 3 locations in SEA: Bulacan Province, Philippines (N=316), Bangkok, Thailand (N=106) and Singapore City (N=61). Maternal exposure to tobacco smoke was 71.1% (1.3% active; 69.8% passive) in Bulacan, 57.5% (0.9% active; 58.6% passive) in Bangkok and 54.1% (11.5% active; 42.0% passive) in Singapore. Fetal exposure to tobacco smoke (by meconium analysis) was 1.3% (Bulacan), 4.7% (Bangkok) and 13.1% (Singapore); however, a large proportion of infants who tested positive for cotinine (65%) were born to mothers who gave no history of either active or passive exposure to environmental tobacco smoke. Fetal exposure to tobacco smoke is a major health problem.

Factors affecting neurodevelopmental outcome at 2 years in very preterm infants below 1250 grams: a prospective study.

OBJECTIVE: To evaluate the neurodevelopmental outcomes of preterm very-low birth weight (PT/VLBW) infants at 2 years and identify risk factors associated with significant developmental delay or neurodevelopmental impairment (NDI). STUDY DESIGN: We evaluated 165 PT/VLBW infants born between January 2010 and December 2011, using the Bayley Scales of Infant and Toddler Development 3rd Edition (Bayley-III). NDI was defined as the presence of neurosensory impairment or significant delay with Bayley-III score < 70 in any domain and risk factors for delay/NDI were assessed using logistic regressions. RESULTS: Median Bayley-III composite scores in the cognitive, language and motor domains were 95, 89 and 94, respectively. NDI was present in 20% of the children, with 5-18% having significant delay in either cognitive, language or motor domain, seven (4%) children had cerebral palsy, three (2%) were deaf and none were blind. Regression models identified significant positive associations of delayed cognitive skills with male gender (Odds ratio (OR) 22.4, 95% confidence interval (CI) 1.5-341.1; P = 0.025), lack of anntenatal steroids (ANS) (OR 41.5, 95% CI 3.5-485.7; P = 0.003), and hypotension needing inotropes (OR 36.0, 95% CI 2.6-506.0; P = 0.008); delayed language skills with lower maternal education (OR 3.8, 95% CI 1.4-10.3; P = 0.10), lack of ANS (OR 2.8, 95% CI 1.1-7.4; P = 0.04), and 5 minute Apgar Score ≤ 5 (OR 7.4, 95% CI 1.4-38.4; P = 0.017) and delayed motor skills with chronic lung disease at 36 weeks (OR 38.3, 95% CI 2.4-603.4; P = 0.010). NDI was associated with lack of ANS (OR 2.91, 95% CI 1.21-7.00; P = 0.02) and use of postnatal steroids (OR 3.36, 95% CI 1.07-10.54; P = 0.0374). CONCLUSION: Risk factors for both NDI and individual domain delay were identified and will be helpful in planning of specific and targeted early intervention services.
