Filter by:Artificial airways, such as endotracheal tubes and tracheostomies, in the pediatric and neonatal intensive care units (PICU, NICU respectively) are lifesaving for patients in respiratory failure, among other conditions. These devices are not without a risk of infection - ventilator-associated infections (VAIs), namely ventilator associated pneumonia (VAP) and ventilator-associated tracheitis (VAT), are common. Treatment of suspected VAI accounts for nearly half of all Pediatric Intensive Care Unit (PICU) antibiotic use. VAI can represent a continuum from tracheal colonization, progression to tracheobronchial inflammation, and then pneumonia. Colonization of these airways is common and bacterial growth does not necessarily indicate a clinically significant infection. Tracheostomies, which are artificial airways meant for chronic use, are routinely exchanged on a semi-monthly to monthly basis, in part to disrupt bacterial biofilm formation that aids bacterial colonization and perhaps infection. When patients with tracheostomies are admitted for acute on chronic respiratory failure or a concern for an infection, these artificial airways are also routinely exchanged at some institutions. There however remains a critical need to understand how an artificial airway exchange alters the bacterial environment of these patients in sickness and in health. This research hypothesizes that exchanging an artificial airway will alter the microbiome of the artificial airway, by altering the microbial diversity and relative abundance of different bacterial species of the artificial airway. This study will involve the prospective collection of tracheal aspirates from patients with artificial airways. We will screen and enroll all patients admitted to a the NICU or PICU at Cohen Children's Medical Center (CCMC) who have tracheostomies and obtain tracheal aspirates within 72 hours before and after tracheostomy or endotracheal tube exchange. Tracheal aspirates are routinely obtained in the NICU and PICU from suctioning of an artificial airway and is a minimal risk activity. These samples will be brought to the Feinstein Institutes for Medical Research for 16 s ribosomal DNA (16srDNA) sequencing, which allows for accurate and sensitive detection of relative abundance and classification of bacterial flora. Tracheal aspirate sets will be analyzed against each other. Additionally, clinical and epidemiological data from the electronic medical record will be obtained. Antibiotic exposure will be accounted for via previously published means.
Urinary tract infections (UTI) are commonly encountered in children, with 7% diagnosed with at least one UTI by the age of 19 years. The evidence for treatment of uncomplicated UTI is clear; oral antibiotics are as good as intravenous (IV) antibiotics, usually for a total of 7 days. Complicated UTIs (cUTIs) on the other hand, are common reasons for hospital admissions for IV antibiotics and constitute a major burden for healthcare systems. There is considerable variation in care for children who present with UTI and have complicating features such as vomiting, dehydration, urological abnormalities or have a previous history of UTI. Australian and international guidelines lack clear, evidence-based recommendations to guide treatment in this group. Without gold standard evidence, these children will continue to receive unnecessary IV antibiotics, longer hospital stays and poorer health outcomes. This multicentre, non-inferiority randomised trial will investigate if One dose - single dose of IV followed by 2 days oral antibiotics is as non-inferior to Three doses for children with UTI and co-existing complicating factors presenting to the Emergency Department (ED). In other words, this study will compare if a single dose of IV antibiotics plus two days oral antibiotics is as clinically effective as 3 doses antibiotics in resolving UTI symptoms at 72 hours after the first dose of IV antibiotics, for complicated UTIs in children presenting to the ED. All participants will receive a total of 7 days of antibiotics for the complicated urinary tract infection. If 1 dose IV and 2 days oral antibiotics is found to be as good as 3 days, the duration of IV antibiotics for complicated UTI can be reduced along with avoidance of the inherent risks of unnecessary hospital admission by administering a single IV dose in an outpatient/ED setting. On the other hand if a single IV dose results in prolonged symptoms or treatment failure, this will inform practice for the proportion of children who have a single dose of IV antibiotics in the ED and are sent home on oral antibiotics. Regardless of the outcome, this trial will inform clinical practice for complicated UTI to improve health outcomes for this group.
