Project description:Objective: Identify genes that are differentially expressed between critically ill trauma patients who go on to develop ventilator-associated pneumonia (VAP) compared to similar patients who do not develop VAP Using gene expression differences, develop a model that predicts which patients are at greater risk of developing VAP. Prospective observational study, analysis of gene expression in 20 patient samples, 10 that developed ventilator-associated pneumonia, 10 that did not
Project description:The onset of an infection-specific transcriptional program precedes the clinical diagnosis in patients who developed Ventilator-associated pneumonia (VAP). Ventilator-associated tracheobronchitis (VAT) is another respiratory infection affecting<br><br>outcomes in intubated patients, but interactions between VAT and VAP remains unknown.
Project description:This project was a prospective translational study aimed at evaluating gene expression profiles (GEP) of patients with ventilator-associated pneumonia (VAP) . GEP of VAP were compared with a control group of patients which did not developed ventilator-associated lower respiratory tract infection despite being subjected to mechanical ventilation.
Project description:Acinetobacter baumannii causes high mortality in ventilator-associated pneumonia patients and antibiotic treatment is compromised in multi-drug resistant strains resistant to beta-lactams, carbapenems, cephalosporins, polymyxins and tetracyclines. Among COVID-19 patients receiving ventilator support, multi-drug resistant A. baumannii secondary infection is associated with a two-fold increase in mortality. Here we investigated the use of the 8-hydroxyquinoline ionophore PBT2 to break resistance of A. baumannii to tetracycline class antibiotics.

Project description:Pseudomonas aeruginosa in mechanically ventilated patients with ventilator-associated pneumonia
Project description:Ventilator associated pneumonia (VAP) is the 2nd most common hospital acquired infection associated with high morbidity, mortality and increased hospitalization. Current practice of diagnosis is based on clinical symptoms and bronchoalvolar lavage (BAL) culture. The procedures of BAL collections are invasive whereas, endotracheal aspirate (ETA), a matrix of upper airway collection is minimally invasive and underexplored in VAP diagnosis. The study describes first in detail characterization of proteome of longitudinal ETA collections from 16 intubated patients including 11 VAP patients and explores potential utility of ETA in VAP diagnosis.
