Project description:Development of the gut microbiota is greatly impacted in preterm infants. Despite increasing knowledge about microbiota composition in preterm infants, knowledge about the functional signatures of the intestinal microbiota remains limited. The aim was to study transitions in microbiota activity during the first six postnatal weeks in ten preterm infants. A total of 64 stool samples were measured by LC-MS/MS.

Project description:Extreme preterm infants are a growing population in neonatal intensive care units who carry a high mortality and morbidity. Multiple factors play a role in preterm birth, resulting in major impact on organogenesis leading to complications including bronchopulmonary dysplasia (BPD). The goal of this study was to identify biomarker signatures associated with BPD severity. We analyzed profiles in tracheal aspirates (TAs) from 25 extremely preterm infants receiving invasive mechanical ventilation. Eight infants were diagnosed with mild/moderate BPD, and 17 were diagnosed with severe BPD, according to the NHLBI consensus conference classification . We found specific miRNA signatures in TAs that may serve as biomarkers for BPD severity.

Project description:Extreme preterm infants are a growing population in neonatal intensive care units who carry a high mortality and morbidity. Multiple factors play a role in preterm birth, resulting in major impact on organogenesis leading to complications including bronchopulmonary dysplasia (BPD). The goal of this study was to identify biomarker signatures associated with prematurity and BPD. We analyzed miRNA and mRNA profiles in tracheal aspirates (TAs) from 51 infants receiving invasive mechanical ventilation. 25 infants were extremely preterm and diagnosed with BPD, and 26 were term babies receiving invasive mechanical ventilation for elective procedures. We found specific mRNA-miRNA signatures in TAs that may serve as biomarkers for BPD pathogenesis, a consequence of extreme prematurity.

Project description:91 preterm infant gut metaproteomes measured in technical duplicate using an eleven salt pulse 2D-LC-MS/MS method. Samples represent 17 preterm infants over the first several weeks of life, of which 6 preterm infants eventually developed necrotizing enterocolitis.

Project description:Extreme preterm infants are a growing population in the neonatal intensive care unit. Multiple factors play a role in preterm birth, resulting in complications including severe bronchopulmonary dysplasia (sBPD) without or with and pulmonary hypertension (BPD-PH). The goal of this study was to identify biomarker signatures associated with sBPD and BPD-PH. We analyzed profiles in tracheal aspirates (TAs) from 46 extremely preterm infants receiving invasive mechanical ventilation (25 sBPD, 21 BPD-PH) . We found specific miRNA signatures in TAs that may serve as biomarkers for the two disease phenotypes.

Project description:There is little information regarding the allergen content of milk feeds in the preterm population. Previous studies have evaluated specific proteins/peptides via ELISA, but no studies have performed a broad analysis of the allergenic peptide content and protease activity of milk feeds in this population. Preterm infants spend a critical window of time for immune development in the Newborn Intensive Care Unit (NICU), and may receive fortified donor milk, maternal milk or formula feeds via nasogastric tube or bottle instead of fresh breastmilk via breastfeeding.

Project description:To investigate early blood biomarkers of BPD development, RNA from cord blood cells or peripheral blood cells of premature infants was subjected to RNA sequencing (RNA-Seq) and data were analyzed with 9 covariates including gestational age (GA), sex, birth weight (BW), estimated CD4+T cell%, CD8+T cell%, B cell%, monocyte%, granulocyte%, and nucleated red blood cell (NRBC)%. The effect of prolonged oxygen (>14 days O2) treatment in newborn intensive care unit on blood cell transcriptome was determined among nonBPD preterm infants.
