NCT00890136
This project aims to characterize the independent effect of domestic endotoxin exposure on health status, as well as pulmonary and systemic inflammation, in former smokers with COPD. Positive findings from this study would be clinically relevant, as they would provide evidence to support aggressive reduction of ongoing endotoxin exposure in patients with COPD. The investigators also hope to make a methodological advance in the field of endotoxin exposure assessment by elucidating whether settled dust and/or airborne endotoxin measurements are the more relevant exposure of interest in epidemiological studies of respiratory disease. To fulfill the specific aims, the investigators will conduct a longitudinal study, including 75 former smokers with COPD. All subjects will have indoor air monitoring, in-home settled dust collections, home inspections as well as assessments of health status, quality of life (QOL), lung function and pulmonary and systemic inflammation.
NCT03995836
This study evaluates epigenetics in morbid obese patients who are waiting for bariatric surgery. A home cardiopulmonary polygraphy is performed to evaluate for the presence of sleep-disordered breathing. The principal investigator make the decision of starting CPAP among patients with obstructive sleep apnea according to current clinical guidelines. One year follow up after bariatric surgery will be performed. A total of 5 visits will be scheduled: two of them before bariatric surgery and 3 after (3, 6 and 12 months). At every visit, all patients had: sleep questionaries, blood samples, EKG-Holter and spirometry are collected.
NCT02121912
Participants will undergo a normal sleep study. They will be randomised to use either a FPH Pilairo Q nasal pillow CPAP mask, or another mask. The sleep technician will record leak and pressure data, and complete questionnaires regarding satisfaction and ease of use at the end of the night. It is hypothesised that the Pilairo Q mask will be superior to other standard masks for CPAP therapy in terms of ease of use, satisfaction and overall titration experience.
