Active clinical trials for "Lung Diseases"

To identify physiological and clinical measures of obstructive sleep-disordered breathing that are associated with increased morbidity in children.

To conduct a baseline survey on cardiovascular, respiratory, and other major systemic disease and risk factors in members of the Vietnam Era Twin Registry.

To test specific hypotheses concerning environmental, occupational, lifestyle, and other risk factors for sarcoidosis. Also, to examine the familial aggregation of sarcoidosis and to test genetic hypotheses concerning its etiology. Finally, to describe the natural history of sarcoidosis, particularly in African-Americans who appear to be disproportionately affected, and to implement a system for storing biological specimens including blood cells, plasma, and serum.

To establish a population-based registry of interstitial lung disease in Bernalillo County, New Mexico.

To provide information on morbidity and health care utilization for asthma for a large, well-defined population over a 20 year period.

To determine the prevalence and longitudinal course of sleep apnea among men and women and to examine the associations of apnea, oxygen desaturation, snoring, high blood pressure, and other biomedical correlates.

To identify sarcoidosis susceptibility genes and to determine how these genes and environmental risk factors interact to cause sarcoidosis.

To conduct a longitudinal study of the relationship between the rate of decline of pulmonary function and measurements of cortisol concentration and excretion in a sample of middle-aged and older men and their wives. The study tested the hypothesis that persons whose plasma cortisol concentrations were relatively low, albeit within the normal range, were predisposed to excessively rapid deterioration of pulmonary function during aging.

To provide information necessary for the development of standards for peak expiratory flow (PEF) test performance in populations studies.

To study three possible, but yet unproven, influences on pediatric asthma hospitalization rates - diagnostic substitution, different systems of medical care, and asthma medication use.
