NCT01599845
Investigation of the differences between the levels of extracellular and intracellular nano-particles in workers exposed to environmental particles during their employment to enhance understanding the process of penetration of the particles to respiratory epithelial cells.
NCT01118104
People with chronic respiratory disease have shortened work life, their disease is associated with greater work disability and they are at greater risk of being unemployed. Lower employment rates and higher sickness absence is expensive for the community and leads to financial as well as social consequences for the individual. There is a lack of data on factors that can predict sickness absence and disability in patients with pulmonary disease. We therefore want to study a group of people with COPD and asthma referred to our clinic. The study will investigate relationships between sickness absence and exercise capacity, job-related factors, disease severity, self-efficacy, health related quality of life and subjective health complaints.
NCT00628329
We wish to understand the association of Vitamin A serum levels and Vitamin A receptor number and responsiveness in asthmatics. We believe that Vitamin A receptors may be less prevalent in asthmatics and their responsiveness decreased.
NCT00000563
To determine the effect of corticosteroids, administered 24 to 48 hours before parturition, on the incidence of neonatal respiratory distress syndrome (RDS) and to determine whether the therapy has any adverse short- or long-term (up to 36 months) effects on the infant. Secondarily, to determine whether the therapy has any adverse short-term effects on the mother and to determine whether morbidity rates for neonatal respiratory distress syndrome as well as total and cause-specific infant mortality rates differ between mothers who received antenatal steroids and those who received conventional medical care.
