Premature infants are at high risk for brain injuries such as intraventricular hemorrhage and periventricular white matter injury. This study applies omics technology to analyze urinary protein expression, aiming to clarify preterm brain injury mechanisms and identify therapeutic targets. Urine samples were collected from 29 very preterm infants (VPI) without brain injury and 11 with moderate/severe injury at eight time points: Days 1, 2, 3, 4, 6, 8, 28, and term-equivalent age (TEA).

Whole blood transcriptional responses of very preterm infants during late-onset sepsis

Project description:Host immune responses during late-onset sepsis (LOS) in very preterm infants are poorly characterised due to a complex and dynamic pathophysiology and challenges in working with small available blood volumes. We present here an unbiased transcriptomic analysis of whole peripheral blood from very preterm infants at the time of LOS. RNA-Seq was performed on peripheral blood samples (6 – 29 days postnatal age) taken at the time of suspected LOS from very preterm infants <30 weeks gestational age. Infants were classified based on blood culture positivity and elevated C-reactive protein concentrations as having confirmed LOS (n=5), possible LOS (n=4) or no LOS (n=9). Bioinformatics and statistical analyses performed included pathway over-representation and protein-protein interaction network analyses. Plasma cytokine immunoassays were performed to validate differentially expressed cytokine pathways.The blood leukocyte transcriptional responses of infants with confirmed LOS differed significantly from infants without LOS (1,317 differentially expressed genes). However, infants with possible LOS could not be distinguished from infants with no LOS or confirmed LOS. Transcriptional alterations associated with LOS included genes involved in pathogen recognition (mainly TLR pathways), cytokine signalling (both pro-inflammatory and inhibitory responses), immune and haematological regulation (including cell death pathways), and metabolism (altered cholesterol biosynthesis). At the transcriptional-level cytokine responses during LOS were characterised by over-representation of IFN-α/β, IFN-γ, IL-1 and IL-6 signalling pathways and up-regulation of genes for inflammatory responses. Infants with confirmed LOS had significantly higher levels of IL-1α and IL-6 in their plasma. Blood responses in very preterm infants with LOS are characterised by altered host immune responses that appear to reflect unbalanced immuno-metabolic homeostasis.

Data in support of nutrition for improved growth and health of very preterm infants

Project description:Impaired growth and nutrition after preterm birth is associated with morbidities and poor neurodevelopmental outcome, but it is not clear whether this reflects causal relationships. To improve growth, human milk is often fortified with protein, energy and minerals, providing small, but significant, fortification-induced gains in body weight, length and/or head circumference. the effect of Bovine Colostrum fortification on AAs and proteins in plasma, and how fortification-induced AA changes during the first two weeks of fortification associated with changes in anthropometric measures, gestational age (GA) at birth, birth weight, key morbidities (BPD, ROP, LOS) and IGF-1 levels. Collectively, the analyses shed light on the complex interplay between fortification-induced changes to plasma AA/protein levels and the growth and morbidities in very preterm infants fed fortified human milk.

Single-cell RNA sequencing of PBMCs from five healthy (HC) preterm infants and ten preterm infants with bronchopulmonary dysplasia(BPD)

Project description:We procured PBMCs whole blood from five HC preterm infants and five preterm infants with BPD. PBMCs were extracted using a density gradient centrifugation method. Initially, 10ml of peripheral blood was mixed with an equal volume of physiological saline, then carefully layered onto Ficoll solution (T10124, from Shangbao Biotech Co., Ltd., Shanghai). After centrifugation at 2,000 rpm for 20 minutes, the cells stratified due to differences in density, with PBMCs positioned between the red blood cells and plasma. Subsequently, the intermediate layer containing PBMCs was gently collected, washed several times with physiological saline to remove residual medium and red blood cells, and finally, PBMCs were isolated and collected through centrifugation.

Adverse effects of small for gestational age differ by gestational week among very preterm infants.

Project description:ObjectiveTo characterise the excess risk for death, grade 3-4 intraventricular haemorrhage (IVH), bronchopulmonary dysplasia (BPD) and stage 3-5 retinopathy of prematurity independently associated with birth small for gestational age (SGA) among very preterm infants, stratified by completed weeks of gestation.MethodsRetrospective cohort study using the Optum Neonatal Database. Study infants were born <32 weeks gestation without severe congenital anomalies. SGA was defined as a birth weight <10th percentile. The excess outcome risk independently associated with SGA birth among SGA babies was assessed using adjusted risk differences (aRDs).ResultsOf 6708 infants sampled from 717 US hospitals, 743 (11.1%) were SGA. SGA compared with non-SGA infants experienced higher unadjusted rates of each study outcome except grade 3-4 IVH among survivors. The excess risk independently associated with SGA birth varied by outcome and gestational age. The highest aRD for death (0.27; 95% CI 0.13 to 0.40) occurred among infants born at 24 weeks gestation and declined as gestational age increased. In contrast, the peak aRDs for BPD among survivors (0.32; 95% CI 0.20 to 0.44) and the composites of death or BPD (0.35; 95% CI 0.24 to 0.46) and death or major morbidity (0.35; 95% CI 0.24 to 0.45) occurred at 27 weeks gestation. The risk-adjusted probability of dying or developing one or more of the evaluated morbidities among SGA infants was similar to that of non-SGA infants born approximately 2-3 weeks less mature.ConclusionThe excess risk for neonatal morbidity and mortality associated with being born SGA varies by adverse outcome and gestational age.

Airway Exosomal miRNA predicts Bronchopulmonary Dysplasis in Extremely Preterm Infants

Project description:We conducted a prospective cohort study with independent Discovery and Validation cohorts, to formulate predictive biomarkers for Bronchopulmonary Dysplasia in extremely preterm infants. Tracheal aspirate samples were collected at birth from extremely preterm infants. Exosomes were extracted from tracheal aspirates and total RNA was extracted from these exosomes from individual samples. miRNA profiling for all ~ 800 miRNAs was conducted on each sample by nanostring platform. This study found that a distinct airway exosomal miRNA sigrature at birth (decreased miR 876-3p) predicts future development of severe Bronchopulmonary Dysplasia in extremely preterm infants.

Distinct maternofetal immune signatures delineate preterm birth onset following urinary tract infection

Project description:Preterm birth is the leading cause of infant mortality resulting in over one million neonatal deaths annually. Maternal urinary tract infection (UTI) during pregnancy increases risk for preterm birth; however, biological processes mediating UTI-associated preterm birth are not well-described. We established a murine maternal UTI model in which challenge with uropathogenic E. coli resulted in preterm birth in about half of dams. Dams experiencing preterm birth displayed excessive bladder inflammation and altered uteroplacental T cell polarization compared to non-laboring infected dams, with no differences in bacterial burdens. Additional factors associated with preterm birth included higher proportions of male fetuses and lower maternal serum IL-10. Furthermore, exogenous maternal IL-10 treatment absolved UTI-associated preterm birth but contributed to fetal growth restriction in this model.

Integrative analysis of DNA methylation and gene expression data among preterm and/or small for gestational age infants during perinatal period [methylation]

Project description:Preterm or small for gestational age (SGA) infants are to be at high risk of noncommunicable diseases in adolescence, because they are exposed to hypoxia and malnutrition in and ex utero during perinatal period. Epigenetics could be one of the most important mechanisms of DOHaD.In the field of premature babies, previous studies investigated the methylation alterations related to gestational age and birthweight by using cord blood samples. In the field of preterm or SGA babies, there were few EWAS studies that examine whether methylation changes relate to RNA expression using cord blood samples, and the interpretation of postnatal blood methylation were different by studies.The objective is to investigate the epigenetic alterations associated with preterm birth and SGA by using methylation and expression microarray, and to explore the epigenetic changes which may persist after birth.
