Study TitleThe impact of tobacco smoke exposure and environmental exposures on the pulmonary microbiome of critically ill children
Study SummaryThis project evaluates the effects of tobacco smoke exposure (TSE) on the pediatric lung microbiome in critically ill children. The impact of TSE on the airway microbiome of critically ill, mechanically ventilated pediatric patients will be determined by through clinical outcomes and analysis of urinary and plasma metabolomes to identify other environmental exposures contributing to the alteration of the pediatric microbiome.

Collection:

Collection ID:CO001324
Collection Summary:Urine samples were collected from participants in the longitudinal study, Microbiome, Virome and Host Responses Preceding Ventilator-Associated Pneumonia, as a single specimen collection following intubation. Urine samples were collected non-invasively from indwelling Foley catheters, bed pans or other urine receptacles. Aliquots of urine were transferred to 1.8mL freezer tubes and stores in a -70C freezer. The samples were shipped on dry ice from the University of Colorado Denver biorepository and subsequently to the metabolomics analysis lab at Emory University.
Sample Type:Urine
Storage Conditions:Described in summary

Treatment:

Treatment ID:TR001345
Treatment Summary:Samples were received frozen in aliquouts of <250uL. Prior to analysis, samples were thawed and prepared for HRM analysis using the standard protocols described in the Sample Preparation section.

Sample Preparation:

Sampleprep ID:SP001338
Sampleprep Summary:Samples were prepared for metabolomics analysis using established methods(Johnson et al. (2010). Analyst; Go et al. (2015). Tox Sci). Prior to analysis, plasma aliquots were removed from storage at -80 degrees C and thawed on ice. Each cryotube was then vortexed briefly to ensure homogeneity, and 50 microliters was transferred to a clean microfuge tube. Immediately after, the plasma was treated with 100 microliters of ice-cold LC-MS grade acetonitrile (Sigma Aldrich) containing 2.5 microliters of internal standard solution with eight stable isotopic chemicals selected to cover a range of chemical properties. Following addition of acetonitrile, urine was equilibrated for 30 min on ice, upon which precipitated proteins were removed by centrifuge (14,000 rpm at 4 degrees C for 10 min). The resulting supernatant (100 microliters) was removed, added to a low volume autosampler vial and maintained at 4 degrees C until analysis (<22 h).

Chromatography ID:CH001529
Chromatography Summary:The HILIC column is operated parallel to reverse phase column for simultaneous analytical separation and column flushing through the use of a dual head HPLC pump equipped with 10-port and 6-port switching valves. During operation of HILIC separation method, the MS is operated in positive ion mode and 10 microliters of sample is injected onto the HILIC column while the reverse phase column is flushing with wash solution. Flow rate is maintained at 0.35 mL/min until 1.5 min, increased to 0.4 mL/min at 4 min and held for 1 min. Solvent A is 100% LC-MS grade water, solvent B is 100% LC-MS grade acetonitrile and solvent C is 2% formic acid (v/v) in LC-MS grade water. Initial mobile phase conditions are 22.5% A, 75% B, 2.5% C hold for 1.5 min, with linear gradient to 77.5% A, 20% B, 2.5% C at 4 min, hold for 1 min, resulting in a total analytical run time of 5 min. During the flushing phase (reverse phase analytical separation), the HILIC column is equilibrated with a wash solution of 77.5% A, 20% B, 2.5% C.
