Treatment and investigation of patients with sleep disorders: I am currently conducting a large epidemiological NIH sponsored study to evaluate the ethnic differences in sleep-health and sleep-health knowledge between Hispanics of Mexican descent and Caucasians in San Diego County. I am also interested in the association of snoring-sleep apnea and nocturnal asthma exacerbation. I continue to investigate the role of chemoreceptors in hypertension and obstructive sleep apnea, and the role of micro-arousals from sleep in the activation of the sympathetic nervous system and daytime functioning. We also have NIH sponsored studies looking at the effects of treatment of sleep apnea in Parkinson’s disease and patients with a recent stroke, the effect of CPAP on inflammation in sleep apnea patients, the prevalence of sleep disordered breathing in patients with CHF, and enhancing compliance with CPAP therapy. Other current research projects include the role of sleep duration in the health of U.S. Latinos; Effects of inhaled corticosteroids in the collapsibility of the upper airway and obstructive sleep apnea in asthmatics; Effectiveness of the diagnosis and treatment of sleep apnea using only unattended home sleep studies.
