Genital mycoplasmas, which can be vertically transmitted, have been implicated in preterm birth, neonatal infections, and chronic lung disease of prematurity. Our prior work uncovered 16S rRNA genes belonging to a novel, as-yet-uncultivated mycoplasma (lineage 'Mnola') in the oral cavity of a premature neonate. Here, we characterize the organism's associated community, growth status, metabolic potential, and population diversity. Sequencing of genomic DNA from the infant's saliva yielded 1.44 Gbp of high-quality, non-human read data, from which we recovered three essentially complete (including 'Mnola') and three partial draft genomes (including Trichomonas vaginalis)...

OBJECTIVE: Vitamin D has many important functions in our body. Especially in intrauterine and early infancy periods, Vitamin D plays a major role in bone development, growth, and the maturation of tissues such as lung and brain. Fetus is dependent on the mother in terms of Vitamin D and maternal Vitamin D deficiency results in a Vitamin D deficient newborn. The purpose of this study was to determine the levels of Vitamin D in newborns and to investigate the association between Vitamin D status of the baby and neonatal hypocalcemia...

BACKGROUND: Current sustained lung inflation (SI) approaches use uniform pressures and durations. We hypothesised that gestational age related mechanical and developmental differences would affect the time required to achieve optimal lung aeration, and resultant lung volumes, during SI delivery at birth in lambs. METHODS: 49 lambs, in five cohorts between 118d and 139d gestation (term 142d), received a standardised 40 cmH2O SI, delivered until 10 s after lung volume stability (optimal aeration) was visualised on real-time electrical impedance tomography (EIT), or to a maximum duration of 180 s...

The imaging evaluation of the neonate in respiratory distress has been described since the most early days of pediatric radiology but advances in diagnosis and treatment have changed the patient population presenting with these conditions and altered the imaging findings. In this article, the range of conditions that cause neonatal respiratory distress is depicted, including congenital lung malformations and lung disease in both preterm and full-term infants. An updated approach to the imaging of these conditions is reviewed, with a focus on changes that have resulted from advances in treatment and diagnosis...

Soluble endoglin (sENG) is increased in the amniotic fluid of mothers with pre-eclampsia and chorioamnionitis. Preterm infants born to mothers with these disorders have an increased risk of aberrant lung development. Whether this increased risk is secondary to elevated sENG levels is unclear. The objective of this study was to determine whether intrauterine exposure to an adenovirus over-expressing sENG impairs neonatal lung angiogenesis by modulating lung eNOS signaling. Pregnant Sprague-Dawley rats were randomly assigned to receive ultrasound guided intra-amniotic injections of adenovirus over-expressing sENG (Ad-sENG) or control adenovirus (Ad-control) on embryonic day 17 (E17)...

Bronchopulmonary dysplasia (BPD) is a syndrome of respiratory distress caused by chronic lung injury, primarily in preterm infants. miR-206 and fibronectin 1 (FN1) are associated with the development of BPD. The present study used rat type II alveolar epithelial cells (AECII) to investigate the underlying mechanisms of BPD. AECII were isolated using a primary cell culture prior to alkaline phosphatase staining and immunofluorescence of surfactant protein C (SP-C). These were used to verify the presence of AECII...

Hyperoxia is one of the primary causes of bronchopulmonary dysplasia, which may occur in premature infants following supplemental oxygen therapy. Glucose regulated protein 78 (GRP78), which is a molecular chaperone located in the lumen of the endoplasmic reticulum (ER), has been reported to regulate hyperoxia‑associated ER stress. The role of GRP78 in lung epithelial cells during hyperoxia remains to be elucidated. In the present study, the A549 cultured human lung epithelial cell line was exposed to hyperoxic conditions, and then transfected with short interfering (si)RNA targeted to GRP78...

Childhood respiratory illness is a major cause of morbidity and mortality particularly in low and middle-income countries. Environmental tobacco smoke (ETS) exposure is a recognised risk factor for both acute and chronic respiratory illness. Areas covered: The aim of this paper was to review the epidemiology of ETS exposure and impact on respiratory health in children. We conducted a search of 3 electronic databases of publications on ETS and childhood respiratory illness from 1990-2015. Key findings were that up to 70% of children are exposed to ETS globally, but under-reporting may mask the true prevalence...

BACKGROUND: Iron deficiency in children can have significant neurological consequences, and iron supplementation is an effective treatment of choice. However, traditional routes of iron supplementation do not allow efficient iron delivery to the brain due to the presence of the blood-brain barrier. So an easily delivered iron formulation with high absorption efficiency potentially could find widespread application in iron deficient infants. RESULTS: In this study, we have developed and characterized a nanovesicular formulation of ferric ammonium citrate (ferric ammonium citrate nanoliposomes, FAC-LIP) and have shown that it can increase brain iron levels in rats following nasal administration...

Respiratory syncytial virus (RSV) is a major viral pathogen that causes severe lower respiratory tract infections in infants and the elderly worldwide. Infants with severe RSV bronchiolitis tend to experience more wheezing and asthma in later childhood. Because invariant natural killer T (iNKT) cells are associated with the asthma pathology, we investigated whether neonatal iNKT cells are involved in the aggravation of pulmonary diseases following RSV infection in mice. Intranasal exposure to the iNKT cell ligand α-galactosylceramide (α-GC) with RSV primary infection in neonatal mice elicited neither cytokine production (except for a slight increase of IL-5) nor pulmonary eosinophilia, despite the presence of both CD1d+ cells and NKT cells...

Bronchopulmonary dysplasia (BPD) is the most common chronic respiratory complication of preterm birth. Preterm infants are at risk for acute lung injury immediately after birth, which predisposes to BPD. In this article, we review the current evidence for interventions applied during neonatal transition (delivery room and first postnatal hours of life) to prevent BPD in extremely preterm infants: continuous positive airway pressure (CPAP), sustained lung inflation, supplemental oxygen use during neonatal resuscitation, and surfactant therapy including less-invasive surfactant administration...
