Abstract Objective To determine the prevalence and risk factors for poor neurodevelopmental outcome in a cohort of very low birth weight (VLBW) infants. Subjects and methods Four hundred and twenty-two infants of a total of 643 VLBW survivors from a teaching hospital in South India were followed up to assess their neurodevelopmental outcomes. Results Among the 422 children who completed the assessment, results of 359 children whose assessments were done between 18 and 24 months were analysed. Thirty-seven children (10.31%) had poor neurodevelopmental outcome, six children [1.67%] had cerebral palsy, one child had visual impairment and another had hearing impairment. Poor post-natal growth was independently associated with poor neurodevelopmental outcomes in the multivariate analysis (p = 0.045). Neonatal complications were not associated with the developmental outcome. Conclusion Despite lower rates of neonatal complications compared with Western cohorts, significant proportion of VLBW infants had poor neurodevelopmental outcomes. Poor post-natal growth was an important determinant of the developmental outcome

Background: Advancements in perinatal-neonatal care in the last decades has led to improved survival rates of very-low birth weight (VLBW) infants. An association between the level of maternal education and neurodevelopmental outcome has been demonstrated in many European studies. This study evaluates the influence of maternal education level and socio-demographic status on the long-term development of Saudi VLBW infants with birth weight of 1000-1500 grams at a corrected gestational age of 21-24 months. Method: This retrospective cohort study examined prospectively collected data from the period of 2005 to 2016 from the Neonatal Follow-up Program (NFP) at King Khalid University Hospital in Riyadh, Saudi Arabia. Results: A total of 122 VLBW infants with a mean gestational age of 29.57 weeks and mean birth weight 1265 grams were enrolled. There was no statistically significant association between the level of maternal education and neurodevelopmental screening outcome at the age of 21-24 months according to the Bayley Infant Neurodevelopmental Screener (BINS) (p=0.149). Bronchopulmonary dysplasia (BPD) was highly associated with cerebral palsy (p=0.001) and an abnormal BINS score (p=0.010). Conclusion: There was no significant influence of the level of maternal education on the neurodevelopmental screening outcome of VLBW infants at the corrected age of 21-24 months. BPD was the strongest predictor of adverse neurodevelopmental outcome.

Periventricular Hemorrhage

Abstract During the years 1984 to 1987, 459 very low birth weight (VLBW) infants were admitted to a state-designated Level III Neonatal Intensive Care Unit. Cerebral sonography performed in a standardized sequence and graded with the Papile scale diagnosed 97 (21.1%) children with periventricular hemorrhage (PVH). The incidence of PVH declined from a peak of 26.6% in 1985 to 16.4% in 1987, associated with an increase in the incidence of inborn admissions (including maternal transport) from 62.0% in 1984 to 80.4% in 1987. During initial hospitalization, the occurrence of both low-grade (Grades I and II) and high-grade PVH was associated with a significantly higher incidence of perinatal risk factors compared with a concurrent population of VLBW infants without PVH. Developmental follow-up was achieved in 93.3% of VLBW infants without PVH and 95.7% of VLBW infants with PVH who survived their initial hospitalization. The incidence of abnormal outcome ranged from 7 of 37 infants with Grade I PVH to 7 of 8 VLBW infants with Grade IV PVH. Only 1 of 16 VLBW infants with high-grade PVH demonstrated normal motor and cognitive development. Active hydro-cephalus developed in 12 infants; 11 sustained a high-grade PVH. Appropriate treatment of intracranial hypertension did not modify the neurodevelopmental outcome. In conclusion, this regional population of VLBW infants demonstrated a decline in the incidence of PVH during the years 1984 to 1987 associated with an increase in the incidence of inborn admissions. The risk of abnormal neurodevelopmental outcome was elevated for all grades of PVH. A 12.0% incidence of hydrocephalus was associated with high-grade PVH, and appropriate treatment did not alter the poor prognosis.

Objective We examined the effects of maternal hypertensive disorders of pregnancy (HDP) on the mortality and neurodevelopmental outcomes in preterm very low birth weight (VLBW) infants (BW ≤1,500 g) based on their intrauterine growth status and gestational age (GA). Study Design We included singleton VLBW infants born at <32 weeks' gestation registered in the Neonatal Research Network Japan database. The composite outcomes including death, cerebral palsy (CP), and developmental delay (DD) at 3 years of age were retrospectively compared among three groups: appropriate for GA (AGA) infants of mothers with and without HDP (H-AGA and N-AGA) and small for GA (SGA) infants of mothers with HDP (H-SGA). The adjusted odds ratios (AOR) and 95% confidence intervals (CI) stratified by the groups of every two gestational weeks were calculated after adjusting for the center, year of birth, sex, maternal age, maternal diabetes, antenatal steroid use, clinical chorioamnionitis, premature rupture of membranes, non-life-threatening congenital anomalies, and GA. Results Of 19,323 eligible infants, outcomes were evaluated in 10,192 infants: 683 were H-AGA, 1,719 were H-SGA, and 7,790 were N-AGA. Between H-AGA and N-AGA, no significant difference was observed in the risk for death, CP, or DD in any GA groups. H-AGA had a lower risk for death, CP, or DD than H-SGA in the 24 to 25 weeks group (AOR: 0.434, 95% CI: 0.202–0.930). The odds for death, CP, or DD of H-SGA against N-AGA were found to be higher in the 24 to 25 weeks (AOR: 2.558, 95% CI: 1.558–3.272) and 26 to 27 weeks (AOR: 1.898, 95% CI: 1.427–2.526) groups, but lower in the 30 to 31 weeks group (AOR: 0.518, 95% CI: 0.335–0.800). Conclusion There was a lack of follow-up data; however, the outcomes of liveborn preterm VLBW infants of mothers with HDP depended on their intrauterine growth status and GA at birth. Key Points

Behavioural Characteristics

AbstractAssessment of the characteristics of spontaneous movements and behaviour in early infancy helps in estimating developmental outcomes. We introduced the Infant Behaviour Checklist (IBC) and examined the relationship between the behavioural characteristics of low-birth-weight infants and neurodevelopmental outcomes at 6 years of age. The behavioural characteristics during the neonatal (36–43 weeks, adjusted) and early infancy periods (49–60 weeks, adjusted) were assessed in very-low-birth-weight infants. The IBC includes 44 common behaviours. We assessed the appearance of individual behavioural characteristics at each period according to the neurodevelopmental outcome. Of the 143 infants assessed during the neonatal period, 89 had typical development (TD), 30 had intellectual disability (ID), and 24 had autism spectrum disorder (ASD). In 78 infants assessed during early infancy, 40, 21, and 17 had TD, ID, and ASD, respectively. The frequency of appearance of three behaviour-related items was significantly lower in the ID group than in the TD group. The frequency of appearance of three posture- and behaviour-related items was significantly lower, while that of two posture-related items was significantly higher, in the ASD group than in the TD group. Behavioural assessment using the IBC may provide promising clues when considering early intervention for low-birth-weight infants.

Cord Clamping

Low birth weight (LBW), defined as a birth weight of <2,500 g, affects 16% of all newborns and is a risk factor for impaired neurodevelopment as well as adverse cardiovascular and metabolic outcomes, including hypertension. LBW infants include both term, small for gestational age infants and preterm infants. Most LBW infants have only marginally LBW (2,000-2,500 g). Recent advances in neonatal care have significantly improved the survival of very LBW (VLBW) infants (<1,500 g). LBW infants are at high risk of iron deficiency due to low iron stores at birth and higher iron requirements due to rapid growth. Using a factorial approach, iron requirements of LBW infants have been estimated to be 1-2 mg/kg/day, which is much higher than the requirements of term, normal birth weight infants, who need almost no dietary iron during the first 6 months of life. In VLBW infants, blood losses and blood transfusions related to neonatal intensive care, as well as erythropoietin treatment, will greatly influence iron status and iron requirements. The timing of umbilical cord clamping at birth is of great importance for the amount of blood transfused from the placenta to the newborn and thereby total body iron. Delayed cord clamping of LBW infants is associated with less need for blood transfusion, less intraventricular hemorrhage, and less necrotizing enterocolitis. Randomized controlled trials have shown that an iron intake of 1-3 mg/kg/day (1-2 mg for marginally LBW and 2-3 mg for VLBW) is needed to effectively prevent iron deficiency. There is some recent evidence that these levels of iron intake will prevent some of the negative health consequences associated with LBW, especially behavioral problems and other neurodevelopmental outcomes and possibly even hypertension. However, it is also important to avoid excessive iron intakes which have been associated with adverse effects in LBW infants.

The Impact

Nosocomial infections (NIs) are important conditions associated with mortality and morbidity in very low birth weight infants (VLBWIs). The aim of this study was to investigate the impact of NIs and the different subtypes on neurodevelopmental outcomes in a cohort of VLBWIs. VLBWIs born with a gestational age between 23 0/7 and 31 6/7 weeks in a level III neonatal center were enrolled. Neonatal morbidities as well as the neurodevelopmental outcome at 2 years of corrected age were analyzed. Six-hundred infants completed the study successfully. Of these, 38% experienced an NI episode. NIs were associated with an increased risk of neonatal complications, such as brain injury, bronchopulmonary dysplasia (BPD) and death, and were a significant risk factor for adverse motor development at 2 years of corrected age in our cohort of VLBWIs. The negative impact of NIs on neurodevelopmental outcomes was particularly associated with necrotizing enterocolitis (NEC), suspected NIs and Gram-positive NIs. This study demonstrated that NIs are a significant risk factor for both morbidity and mortality as well as adverse neurodevelopmental outcomes in VLBWIs.
