Active clinical trials for "Asthma"

In our previous study of Methacholine Challenge Tests (MCT) in preschool children, we found that wheeze detection was associated with significant reduction in flows and vital capacity values. We hypothesized that this finding is associated with trapped-air rather than the children's loss of cooperation/concentration. Objectives: To test this hypothesis by attempting plethysmography measurements during MCT.

Cold and dry air induce exercise induced asthma. Yoga training may improve lung function tests. Bikram Yoga (heat 39 degree Celsius and humidity 60%)training may improve both lung function tests and bronchial hyperreactivity (to exercise and adenosine 5'monophosphate).

To evaluate asthma morbidity in low-income, African-American children and adults with asthma.

To investigate whether isocyanate-induced asthma is dependent on isocyanate antigen-driven T-cell mediated, airway inflammation.

To identify risk factors which predispose individuals to develop asthma and other manifestations of allergic disease on exposure to laboratory animals in the workplace.

To develop and implement asthma controlling strategies for inner city and high risk populations.

To develop and implement asthma controlling strategies for inner city and high risk populations.

Multicenter, cross-sectional study to recruit a random sample of 6000 children via school class registers: 3000 children aged 13-14 years and 3000 children aged 6-7 years.

The primary goal of this proposal is to use an in-home, smartphone-enabled, hand-held spirometer to determine the FEV1% predicted ranges that predict the Yellow Zone threshold.

This study is a cross-sectional, non-interventional study based on existing data (NISed).
