Several phenomena in contemporary perinatology create challenges for analyzing pregnancy outcomes. These include recent increases in iatrogenic delivery at late preterm and early term gestation which are incongruent with the belief that stillbirth and neonatal death risk decrease exponentially with advancing gestational age. Perinatal epidemiologists have also puzzled over the paradox of intersecting birth weight- and gestational age-specific perinatal mortality curves for decades. For example, neonatal mortality rates among preterm infants of women who smoke are substantially lower than neonatal mortality rates among preterm infants of non-smoking women, whereas the reverse pattern occurs at term gestation...

BACKGROUND: Painful procedures are unavoidable in the medical care of preterm babies. The unpleasant experience during the neonatal period may contribute to hyperalgesia and poor neurodevelopment outcome later. Seeking effective interventions to reduce pain are strongly indicated for these very small premature babies. The aim of this study is to investigate if instilling breast milk (BM) or dextrose water into oral cavity can reduce the procedural pain of heel stick for preterm babies...

OBJECTIVES: To (1) compare the neurodevelopmental outcomes at 8 years of age of children born extremely preterm (EP) who underwent surgical procedures during the course of their initial hospital admission with those who did not and (2) compare the outcomes across eras, from 1991 to 2005. DESIGN: Prospective observational cohort studies conducted over three different eras (1991-1992, 1997 and 2005). Surviving EP children, who required surgical intervention during the primary hospitalisation, were assessed for general intelligence (IQ) and neurosensory status at 8 years of age...

REVIEW
Lex W Doyle, Jeanie L Y Cheong
Newborn infants born very preterm are at high risk of developing bronchopulmonary dysplasia, which is associated with not only mortality but also adverse long-term neurological and respiratory outcomes in survivors. Postnatal corticosteroids might reduce the risk of developing bronchopulmonary dysplasia, or reduce its severity. However, it is important to minimize exposure to the potentially harmful effects of corticosteroids, particularly on the developing brain. Systemic corticosteroids started after the first week of life have shown the most benefit in infants at highest risk of developing bronchopulmonary dysplasia, whereas inhaled corticosteroids have little effect in children with established lung disease...

Preterm birth is associated with an increased risk of adverse neurologic, psychiatric, and cognitive outcomes. The brain circuits involved in processing social information are critical to all of these domains, but little work has been done to examine whether and how these circuits may be especially sensitive to prematurity. This paper contains a brief summary of some of the cognitive, psychiatric, and social outcomes associated with prematurity, followed by a description of findings from the modest body of research into social-cognitive development in infants and children born preterm...

PURPOSE: Co-occurring neurodevelopmental disabilities (including cognitive and language delays and attention deficit hyperactivity disorder) affect over half of children with ASD and may affect later behavioral, language, and cognitive outcomes beyond the ASD diagnosis. However, no studies have examined predictors of co-occurring neurodevelopmental disabilities in children with ASD. This study investigated whether maternal sociodemographic, perinatal and neonatal factors are associated with co-occurring disabilities...

BACKGROUND: Preterm birth and small for gestational age (SGA) are strong indicators of neonatal adverse outcomes. With the growing importance of preterm SGA infants, we aim to evaluate the prevalence and risk factors for preterm SGA in China. METHOD: We analyzed the data of parents and infants from a population-based cohort research of the free National Pre-pregnancy Checkups Project (NPCP) in rural China. Only singleton live births that occurred between 24 weeks +0 days and 36 weeks +6 days of pregnancy were included in this study...

BACKGROUND: The analysis of perinatal outcomes often involves datasets with some multiple births. These are datasets mostly formed of independent observations and a limited number of clusters of size two (twins) and maybe of size three or more. This non-independence needs to be accounted for in the statistical analysis. Using simulated data based on a dataset of preterm infants we have previously investigated the performance of several approaches to the analysis of continuous outcomes in the presence of some clusters of size two...

BACKGROUND: Preterm birth is known to constitute the major risk factor for development of germinal matrix-intraventricular hemorrhage (GM-IVH). Head position may affect cerebral hemodynamics and thus may be involved indirectly in development of GM-IVH. Turning the head toward one side may functionally occlude jugular venous drainage on the ipsilateral side while increasing intracranial pressure and cerebral blood volume. Thus, it has been suggested that cerebral venous pressure is reduced and hydrostatic brain drainage improved if the patient is in supine midline position with the bed tilted 30°...

OBJECTIVES: atresia (BA) occurs in 0.54/10.000 of overall live births in The Netherlands. BA has an unfavorable prognosis: less than 40% of patients are cleared of jaundice after Kasai portoenterostomy (KPE), 4-year transplant-free survival rate is 46% and the 4-year survival rate is ∼75%. Little is known on difficulties in diagnosis and the outcome of BA in preterm infants. We aimed to analyze the incidence and outcome of BA in preterm infants in The Netherlands. METHODS: Retrospective study including Dutch preterm infants treated for BA...

REVIEW
William E Benitz, Shazia Bhombal
Over the last four decades, non-steroidal anti-inflammatory drugs have been widely used to induce closure of the patent ductus arteriosus (PDA) in preterm infants. Evidence to support this practice is lacking, despite performance of >50 randomized trials. The credibility of those trials may have been compromised by high rates of open treatment in controls, era of study prior to advent of modern practices, or inclusion of insufficient numbers of very immature infants. Meta-analyses show little impact of those factors on main conclusions...

BACKGROUND: Use, timing and doses of surfactant in preterm infants are variable in practice in modern NICUs. OBJECTIVE: To explore the association between use and timing of surfactant administration and common neonatal adverse outcomes in preterm infants with gestational age (GA) < 28 weeks. MATERIAL AND METHODS: Neonates admitted to a participating Canadian Neonatal Network NICU between 2013 and 2015 were studied. Infants were divided into three groups based on surfactant administration: None, early (within 30 minutes of life), and late surfactant (> 30 minutes)...

IMPORTANCE: Postnatal dexamethasone is associated with reduction in bronchopulmonary dysplasia. There remains, however, concern that its short-term benefits are accompanied by long-term adverse effects e.g. poorer neurodevelopmental outcomes. OBJECTIVE: Our aim was to determine the effects of administration of postnatal dexamethasone on respiratory and neurodevelopmental outcome at two years of age after adjusting for neonatal and infant risk factors. MATERIALS AND METHODS: The study included 412 infants born at 23-28 weeks of gestation, 29% had received postnatal dexamethasone...

Currently no treatments exist for preterm infants with diffuse white matter injury (DWMI) caused by hypoxia. Due to improved care of preterm neonates and increased recognition by advanced imaging techniques, the prevalence of DWMI is increasing. A better understanding of the pathophysiology of DWMI is therefore of critical importance. The integrated stress response (ISR), a conserved eukaryotic response to myriad stressors including hypoxia, may play a role in hypoxia-induced DWMI and may represent a novel target for much needed therapies...
