  • Sleep-Related Determinants of Stroke Scottsdale/Phoenix, AZ

    Stroke is the second leading cause of death worldwide. Traditional stroke risk factors explain about half of the risk for stroke. The remaining half may be partially explained by sleep duration and disturbances, which are prospectively related to incident stroke across multiple populations. Although these relationships have been identified, at present, essentially nothing is known regarding the modifiable, sleep-inhibiting behaviors that determine sleep duration and disruption; these are probable targets of stroke prevention. The study proposed here is intended to fill this void by determining the relation between sleep-inhibiting behaviors, self-reported sleep duration and disruption, and stroke amongst acute stroke ...

    The purpose of this study is to test for the long-term outcomes in function for stroke patients who get an early tracheostomy, versus those who have prolonged orotracheal intubation. 

    Patients with severe ischemic and hemorrhagic strokes, who require mechanical ventilation, have a particularly bad prognosis. If they require long-term ventilation, their orotracheal tube needs to be, like in any other intensive care patient, replaced by a shorter tracheal tube below the larynx. This so called tracheostomy might be associated with advantages such as less demand of narcotics and pain killers, less lesions in mouth and ...

  • A Study of Continuous Positive Airway Pressure Treatment for Obstructive Sleep Apnea to Prevent Cardiovascular Disease Rochester, MN

    Obstructive Sleep Apnea (OSA) is a condition in which a person stops breathing for several seconds at a time due to relaxation of the throat muscles. This can occur many times during sleep and is known to cause sleepiness and poor concentration during the day. Research indicates that OSA may be a modifiable risk factor for cardiovascular disease due to its association with hypertension, stroke, heart attack and sudden death. The standard therapy for symptomatic OSA is continuous positive airway pressure (CPAP). CPAP has been shown to effectively reduce snoring, obstructive episodes and daytime sleepiness and to modestly reduce blood pressure ...
