BACKGROUND: Premature infants are highly vulnerable to infection. This is partly attributable to the preterm immune system, which differs from that of the term neonate in cell composition and function. Multiple studies have found differential DNA methylation (DNAm) between preterm and term infants' cord blood; however, interpretation of these studies is limited by the confounding factor of blood cell composition. This study evaluates the epigenetic impact of preterm birth in isolated hematopoietic cell populations, reducing the concern of cell composition differences...

BACKGROUND: Intrauterine infection is a significant cause of early preterm birth. We have developed a fetal-neonatal model in the rhesus macaque to determine the impact of chronic intrauterine infection with Ureaplasma parvum on early neonatal reflexes and brain development. METHODS: Time-mated, pregnant rhesus macaques were randomized to be inoculated with U. parvum (serovar 1; 10(5)cfu) or control media at ~120 dGA. Neonates were delivered by elective hysterotomy at 135-147 dGA (term=167d) stabilized and cared for in our nonhuman primate neonatal intensive care unit...

BACKGROUND: Both very preterm (VP; i.e., gestational age <32 weeks) and very low birth weight (VLBW; i.e., birth weight <1,500 grams) are used as inclusion criteria by studies on preterm birth. We aimed to quantify the impact of these entities on postnatal growth until final height. METHODS: Subjects born VP and/or with VLBW from the Project On Preterm and Small-for-gestational-age infants cohort were classified as: (1) VP+/VLBW+ (n=495), (2) VP+/VLBW- (n=207) or (3) VP-/VLBW+ (n=296) infants...

BACKGROUND: Maternal breast milk (MBM) is enriched in microRNAs, factors that regulate protein translation throughout the human body. MBM from mothers of term and preterm infants differ in nutrient, hormone, and bioactive-factor composition, but the microRNA differences between these groups have not been compared. We hypothesized that gestational age at delivery influences microRNA in MBM, particularly microRNAs involved in immunologic and metabolic regulation. METHODS: MBM from mothers of premature infants (pMBM) obtained 3-4 weeks post-delivery was compared with MBM from mothers of term infants obtained at birth (tColostrum) and 3-4 weeks post-delivery (tMBM)...

Despite the recent improvements in perinatal medical care leading to an increase in survival rates, adverse neurodevelopmental outcomes occur more frequently in preterm and/or high-risk infants. Medical risk factors for neurodevelopmental delays like male gender or intrauterine growth restriction and family sociocultural characteristics have been identified. Significant data have provided evidence of the detrimental impact of overhelming environmental sensory inputs, such as pain and stress, on the developing human brain and strategies aimed at preventing this impact...

Several cytokines have been detected in human milk but their relative concentrations differ among women and vary over time in the same person. The drivers of such differences have been only partially identified, while the effect of luminal cytokines in the fine-regulation of the intestinal immune system is increasingly appreciated. The aim of this study was to investigate the associations between obstetrical complications and human milk cytokine profiles in a cohort of Peruvian women giving birth to Low Birth Weight (LBW) infants...

BACKGROUND: In 2014, more than 10% of all births in the United States were preterm (born at <37-weeks' gestation). These high-risk infants will often spend weeks to months within the neonatal intensive care unit (NICU), where noise levels can easily reach 120 decibels adjusted (dBA) on a regular and sometimes consistent basis. The American Academy of Pediatrics recommends that NICU sound levels remain below 45 dBA to promote optimal growth and development. PURPOSE: The purpose of this evidence-based brief is to critically appraise the literature concerning preterm infant response to noise within the NICU as well as the use of noise interventions to improve health outcomes for the vulnerable preterm infant population...

BACKGROUND: The hospital environment leaves preterm infants (PTIs) exposed to various stressors that can disrupt their growth and development. Developmental interventions such as music may be an important strategy to mitigate PTI's stress. This brief evaluates current evidence regarding the impact of music therapy on outcomes for PTIs. PURPOSE: The question guiding this brief is "Do various types of music therapy positively affect physiologic indicators, feeding behaviors/length of stay (LOS) and pain management outcomes for PTIs?" SEARCH STRATEGY: CINAHL/MEDLINE Complete and PubMed databases were searched using keywords preterm infants, premature infants, preterm baby, premature baby, NICU baby, music, and music therapy...

BACKGROUND: The use of supplemental oxygen in the care of extremely preterm infants has been common practice since the 1940s. Despite this, there is little agreement regarding which oxygen saturation (SpO₂) ranges to target to maximise short- or long-term growth and development, while minimising harms. There are two opposing concerns. Lower oxygen levels (targeting SpO₂ at 90% or less) may impair neurodevelopment or result in death. Higher oxygen levels (targeting SpO₂ greater than 90%) may increase severe retinopathy of prematurity or chronic lung disease...

AIM: To identify the antecedents and very early correlates of low concentrations of neurotrophic growth factors in the blood of extremely preterm newborns during the first postnatal month. METHODS: Using an immunobead assay, we measured the concentrations of neurotrophin 4 (NT4), brain-derived neurotrophic factor (BDNF), and basic fibroblast growth factor (bFGF) in blood spots collected on postnatal days 1 (N=1062), 7 (N=1087), 14 (N=989), 21 (N=940) and 28 (N=880) from infants born before the 28th week of gestation...

Poor white matter development in intrauterine growth restricted (IUGR) babies remains a major, untreated problem in neonatology. New therapies, guided by an understanding of the mechanisms that underlie normal and abnormal oligodendrocyte development and myelin formation, are required. Much of our knowledge of the mechanisms that underlie impaired myelination come from studies in adult demyelinating disease, preterm brain injury, or experimental models of hypoxia-ischemia. However relatively less is known for IUGR which is surprising because IUGR is a leading cause of perinatal mortality and morbidity, second only to premature birth...

BACKGROUND: Fetal growth restriction (FGR) is associated with increased perinatal mortality and long-term cardiovascular and neurodevelopmental sequelae. We hypothesized that FGR impacts on the development of autonomic heart rate and blood pressure control, contributing to unfavorable short- and long-term outcomes following FGR. METHODS: We studied 25 preterm FGR and 22 preterm and 19 term appropriate-for-gestational-age (AGA) infants. Preterm neonates were studied on postnatal Day 1 and all infants were studied at 1 and 6 months post-term age...

Retinopathy of prematurity is a retinal vasoproliferative disease affecting extremely preterm infants exposed to high concentrations of oxygen therapy. Infants born before 32 post-menstrual weeks or with a birth weight of less than 1500g should systematically have a dilated fundus examination. The time of screening and schedule for follow-up are guided by the various risk factors. This disease results from immaturity of the peripheral retinal vessels at the time of premature birth. The classification of ROP depends on the anteroposterior extent of involvement (from center to periphery: zone I, II and III), its extension in 30° sectors (clock hours) and its stage (stage 1 to 5)...

Purpose To examine whether maternal cancer during pregnancy is associated with increased risks of stillbirth and infant mortality. Methods On the basis of nationwide health registers, we conducted a study of 3,947,215 singleton births in Sweden from 1973 through 2012. Exposure was defined as maternal cancer diagnosed during pregnancy (number of births = 984) or during the year after pregnancy (number of births = 2,723). We calculated incidence rate ratios (IRRs) for stillbirth and infant mortality, comparing exposed births to unexposed births...
