Extubation Readiness Practices and Barriers to Extubation in Pediatric Subjects.

Background: Invasive mechanical ventilation is a lifesaving intervention that is associated with short- and long-term morbidities. Extubation readiness protocols aim to decrease extubation failure rates and simultaneously shorten the duration of invasive ventilation. This study sought to analyze extubation readiness practices at one institution and identify barriers to extubation in pediatric patients who have passed an extubation readiness test (ERT).

Progression of Respiratory Support Following Pediatric Extubation.

Objectives: High-flow nasal cannula and noninvasive positive pressure ventilation have become ubiquitous in contemporary PICUs. Practice patterns associated with the use of these modalities have not been well described. In this study, we aimed to describe the use of high-flow nasal cannula and noninvasive positive pressure ventilation in children after extubation and analyze the progression of usage in association with patient factors.

Marmosets as a preclinical model for testing "off-label" use of doxycycline to turn on Flt3L expression from high-capacity adenovirus vectors.

We developed a combined conditional cytotoxic, , herpes simplex type 1-thymidine kinase (TK), plus immune-stimulatory, , fms-like tyrosine kinase ligand-3-mediated gene therapy for glioblastoma multiforme (GBM). Therapeutic transgenes were encoded within high-capacity adenoviral vectors (HC-Ad); TK was expressed constitutively, while Flt3L was under the control of the TetOn regulatable promoter. We previously assessed efficacy and safety in intracranial GBM rodent models.

Safety profile, efficacy, and biodistribution of a bicistronic high-capacity adenovirus vector encoding a combined immunostimulation and cytotoxic gene therapy as a prelude to a phase I clinical trial for glioblastoma.

Adenoviral vectors (Ads) are promising gene delivery vehicles due to their high transduction efficiency; however, their clinical usefulness has been hampered by their immunogenicity and the presence of anti-Ad immunity in humans. We reported the efficacy of a gene therapy approach for glioma consisting of intratumoral injection of Ads encoding conditionally cytotoxic herpes simplex type 1 thymidine kinase (Ad-TK) and the immunostimulatory cytokine fms-like tyrosine kinase ligand 3 (Ad-Flt3L). Herein, we report the biodistribution, efficacy, and neurological and systemic effects of a bicistronic high-capacity Ad, i.
