Genome sequences of 70 multidrug-resistant Gram-negative isolates in high-risk neonates in the Northeast of Mexico.

Infections by multidrug-resistant pathogens are steadily increasing worldwide. A considerable proportion of neonatal intensive care admissions have a bacterial infection with multidrug-resistant bacteria during their hospital stay. In this work, we report draft genome sequences of 70 selected isolates from high-risk neonates in the Northeast of Mexico.

A cross-sectional study evidences regulations of leukocytes in the colostrum of mothers with obesity.

Background: Breastmilk is a dynamic fluid whose initial function is to provide the most adapted nutrition to the neonate. Additional attributes have been recently ascribed to breastmilk, with the evidence of a specific microbiota and the presence of various components of the immune system, such as cytokines and leukocytes. The composition of breastmilk varies through time, according to the health status of mother and child, and altogether contributes to the future health of the infant.

Aquaporine-5 and epithelial sodium channel β-subunit gene expression in gastric aspirates in human term newborns.

Both transient tachypnea of the newborn and neonatal respiratory distress syndrome have been associated with changes in gene expression of aquaporine-5 (AQP5) and the β subunit of the epithelial sodium channel (β-ENaC) in the respiratory epithelium. Gastric aspirate (GA) obtained immediately after birth could represent a new source for gene expression analysis for these respiratory diseases. The aims of this study were to determine the feasibility of estimating AQP5 and β-ENaC gene expression in exfoliated respiratory epithelial cells from the GA of term neonates, and to compare the values with those found in scraped nasal epithelial cells, previously validated as a surrogate for distal lung epithelium in terms of ionic channel activity.

Can sTREM-1 predict septic shock & death in late-onset neonatal sepsis? A pilot study.

Background And Objectives: The transmembrane glycoprotein TREM-1 triggers an inflammatory response. Its soluble fraction (sTREM-1) has been shown to have diagnostic accuracy for late-onset neonatal sepsis (LONS). Until now, the potential of sTREM-1 to predict septic shock and/or death in septic neonates has not been explored.
