BACKGROUND: White matter (WM) abnormalities associated with prematurity are one of the most important causes of neurological disability that involves spastic motor deficits in preterm newborns. This study aimed to evaluate regional microstructural changes in diffusion tensor imaging (DTI) associated with WM abnormalities. METHODS: We prospectively studied extremely low birth weight (ELBW; <1000 g) preterm infants who were admitted to the Neonatal Intensive Care Unit of Hanyang University Hospital between February 2011 and February 2014...

Preterm infants are susceptible to inflammation-induced white matter injury but the exposures that lead to this are uncertain. Histologic chorioamnionitis (HCA) reflects intrauterine inflammation, can trigger a fetal inflammatory response, and is closely associated with premature birth. In a cohort of 90 preterm infants with detailed placental histology and neonatal brain magnetic resonance imaging (MRI) data at term equivalent age, we used Tract-based Spatial Statistics (TBSS) to perform voxel-wise statistical comparison of fractional anisotropy (FA) data and computational morphometry analysis to compute the volumes of whole brain, tissue compartments and cerebrospinal fluid, to test the hypothesis that HCA is an independent antenatal risk factor for preterm brain injury...

BACKGROUND: In neonatal intensive care unit (NICU), neonatal sleep is disrupted due to different factors. Due to the critical role of sleep in premature infants' brain development, this study aimed to investigate the effect of nesting and swaddling on the sleep duration of premature infants hospitalized in NICUs. MATERIALS AND METHODS: In a crossover clinical trial, 42 preterm infants who met the inclusion criteria were enrolled. They were randomly assigned to two groups of nest-swaddle and swaddle-nest...

: A comprehensive developmental timeline of activity in the mouse cortex in vivo is lacking. Understanding the activity changes that accompany synapse and circuit formation is important to understand the mechanisms by which activity molds circuits and would help to identify critical checkpoints for normal development. To identify key principles of cortical activity maturation, we systematically tracked spontaneous and sensory-evoked activity with extracellular recordings of primary visual cortex (V1) in nonanesthetized mice...

BACKGROUND: The perception of smell and taste, though present early in development, is not routinely considered in the care of preterm infants. Smell and taste are known to increase gut motility, insulin secretion, and the release of appetite, digestive and metabolic hormones. OBJECTIVE: We aimed to investigate the effect of regular smell and taste on the time from birth to full enteral feeds, and the feasibility of the study protocol in very preterm infants. METHODS: In a randomized controlled trial, infants <29 weeks' postmenstrual age (PA) were assigned to receive either the smell and taste of milk before each feed or to have no exposure to the smell and taste of milk (control)...

BACKGROUND: Research has demonstrated that breast milk significantly decreases morbidities that impact length of stay for preterm infants, but there is a need to test interventions to improve breastfeeding outcomes. Since many Americans are using technologies such as the Intranet and smartphones to find health information and manage health, a Web site was developed for mothers who provide breast milk for their preterm hospitalized infants. PURPOSE: This study examined the efficacy of a Web site for mothers to educate them about breast milk expression and assist them in monitoring their breast milk supply...

Preterm labor is often a sudden event that impacts significantly on the health of the premature infant and on parenting behaviors. The prognosis for premature infants correlates positively with the effectiveness of parenting. Therefore, encouraging parental functions is important. The present paper reviews the literature on the concept of family-centered care in the contexts of premature-infant health problems, assesses the impacts of preterm birth on the parental role, and assesses the influences of parental dysfunction...

REVIEW

Caffeine is a methylxanthine that is widely used to treat apnea of prematurity (AOP). In preterm infants, caffeine reduces the duration of respiratory support, improves survival rates and lowers the incidence of cerebral palsy and cognitive delay. There is, however, little evidence relating to the immediate and long-term effects of caffeine on brain development, especially at the cellular and molecular levels. Experimental data are conflicting, with studies showing that caffeine can have either adverse or benefical effects in the developing brain...

A mathematical model of the dynamics of insulin and glucose during a frequently sampled intravenous glucose tolerance test (IVGTT) in sheep was developed that characterizes the large second-phase insulin secretion response in sheep during IVGTT. The model was fit to measurements of the glucose and insulin dynamics during standard IVGTT ( = 42) and modified IVGTT ( = 40), where insulin was injected 60 min after the initiation of the IVGTT. The correlation between log insulin sensitivity determined by hyperglycemic clamps (HGC) and standard IVGTT was = 0...

OBJECTIVE: Episodes of bradycardia are common and recur sporadically in preterm infants, posing a threat to the developing brain and other vital organs. We hypothesize that bradycardias are a result of transient temporal destabilization of the cardiac autonomic control system and that fluctuations in the heart rate signal might contain information that precedes bradycardia. We investigate infant heart rate fluctuations with a novel application of point process theory. METHODS: In 10 preterm infants, we estimate instantaneous linear measures of the heart rate signal in neonates, use these measures to extract statistical features of bradycardia, and propose a simplistic framework for prediction of bradycardia...

REVIEW
Stephen D Bird
The artificial placenta (AP) has for many decades captured the imagination of scientists and authors with popular fiction including The Matrix and Aldous Huxley's "Brave New World", depicting a human surviving ex-utero in an artificial uterine environment (AUE). For scientists this has fascinated as a way forward for extremely preterm infants (EPIs) born less than 28 weeks of gestation. Early successes with mechanical ventilation (MV) for infants born above 28 weeks of gestation meant that AP research lost momentum...

INTRODUCTION: Prematurely born preschoolers show developmental cognitive delay compared to full-term children. There are important neurological networks developing at preschool age related to perspective taking about the attribution of belief and to deduction with contrary-to-fact situations. Other deductive abilities may be completed during that period. METHOD: A group of very prematurely born children (N = 35) aged between 4 and 5 years was compared with a control group of children born at full term (N = 35)...

Megan L Lawlor, Agatha S Critchfield
Intrahepatic cholestasis of pregnancy (ICP) is a complication of pregnancy resulting in elevation of serum bile acid levels. ICP is often associated with underlying liver disease, including hepatitis C. Bile acids in relationship to the acute infection of hepatitis C virus have not yet been delineated in the literature. A 26-year-old gravida 4 para 2103 with dichorionic, diamniotic twin gestation and history of intravenous drug abuse developed ICP in the setting of acute hepatitis C infection. In addition to clinical symptoms of pruritus and right upper quadrant pain, she developed severe elevation in bile acids, 239 micromol/L, and transaminitis aspartate aminotransferase 1033 U/L, and alanine aminotransferase 448 U/L...

BACKGROUND: Antenatal exposure to selective serotonin reuptake inhibitors (SSRI) is associated with an enhanced risk of preterm birth. Very preterm-born neonates (<32-week gestation) antenatally-exposed to SSRIs may show altered brain development. OBJECTIVE: To examine whether antenatal-SSRI exposure was associated with adverse neonatal brain microstructural and metabolic development using diffusion tensor and magnetic resonance spectroscopic imaging. DESIGN/METHODS: Of 177 neonates enrolled, 14 (8%) were antenatally exposed to SSRIs...

INTRODUCTION: Up to 50% of the infants delivered after radical vaginal trachelectomy (RVT) are born prematurely. An effective strategy to reduce this number could be the closure of the cervical os (CCO). PATIENTS AND METHODS: Fifteen pregnant patients who had a RVT due to early cervical cancer were included in this prospective case control study. All patients were scheduled for CCO early in the second trimester. CCO was performed in 12 patients. Their data were compared to data from 125 pregnancies after a RVT without CCO...

BACKGROUND: To study whether maternal serum hyperglycosylated human chorionic gonadotropin (hCG-h) improves first trimester prediction of pre-eclampsia when combined with placental growth factor (PlGF), pregnancy-associated plasma protein-A (PAPP-A) and maternal risk factors. METHODS: Gestational-age-adjusted concentrations of hCG, hCG-h, PlGF and PAPP-A were analysed in serum samples by time-resolved immunofluorometric assays at 8-13 weeks of gestation. The case-control study included 98 women who developed pre-eclampsia, 25 who developed gestational hypertension, 41 normotensive women with small-for-gestational-age (SGA) infants and 177 controls...

BACKGROUND: The cytoarchitecturally defined Edinger-Westphal nucleus (EW) is now referred to by many investigators as the centrally-projecting EW (EWcp) in humans. Although the mature structure is well-characterized, there have been few reports describing the precise morphology of this nucleus during the second half of gestation. SUBJECTS/DESIGN: Eleven brains were examined from preterm infants, aged 20-39 postmenstrual weeks, who died of various causes. After fixation, the brains were embedded in celloidin and serial sections of 30-μm thickness were cut in the horizontal plane...

BACKGROUND: Respiratory distress syndrome (RDS) is a severe pulmonary disease that mainly affects preterm neonates. Surfactant-protein genes' polymorphisms have been mostly evaluated as the candidate contributors in genetics of RDS. However, the results are diverse in different populations. We aimed at investigating the association of rs1124 with RDS development. METHOD: Three hundred and thirty five preterm neonates were enrolled in a multicenter case-control study...

Brain connectivity is associated with axonal connections between brain structures. Our goal was to quantify the interhemispheric neuronal connectivity in healthy preterm infants by automated quantitative EEG time-correlation analysis. As with advancing postmenstrual age (PMA, gestational age  +  postnatal age) the neuronal connectivity between left and right hemisphere increases, we expect to observe changes in EEG time-correlation with age. Thirty-six appropriate-for-gestational age preterm infants (PMA between 27-37 weeks) and normal neurodevelopmental follow-up at 5 years of age were included...
