Up to 50% of patients over 60 years old develop postoperative delirium following cardiac surgery. Delirium increases morbidity and mortality, and may lead to long-term cognitive impairment similar to patients with a diagnosis of Alzheimer's disease. The underlying mechanisms behind delirium are not understood, and therefore the current prevention and treatment strategies are inadequate. Several hypotheses exist for the pathophysiology of delirium, one of which is the role of neuroinflammation. The stress associated with high-risk procedures such as cardiac surgery may lead to systemic inflammation causing endothelial dysfunction and disruption of the blood brain barrier (BBB). When this occurs, the brain is susceptible to neuronal injury via neuroinflammation after which a state of delirium may ensue. To characterize the mechanisms of neuroinflammation in delirium, the investigators will explore the biomarkers most closely linked to each step of the proposed pathway.
NCT00146172
The purpose of this study is to evaluate the safety and tolerability as well as find the maximum tolerated dose (MTD) for HKI-272. In addition, this study will examine the effects of the study drug on your tumor, and how your body uses and eliminates HKI-272.
NCT03026322
Complications are common during endotracheal intubation of critically ill adults. Manual ventilation between induction and intubation ("bag-valve-mask" ventilation) has been proposed as a means of preventing hypoxemia, the most common complication of intubation outside the operating room. Safety and efficacy data, however, are lacking. PreVent is a randomized trial comparing manual ventilation between induction and laryngoscopy to no manual ventilation between induction an laryngoscopy during endotracheal intubation of critically ill adults. The primary efficacy endpoint will be the lowest arterial oxygen saturation. The primary safety endpoints will be the lowest oxygen saturation, highest fraction of inspired oxygen, and highest positive end-expiratory pressure in the 24 hours after the procedure.
