Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

Under daily routine conditions and without any intervention by the sponsor regarding the selection of subjects, diagnostic procedures, therapeutic decisions (medicinal and non- medicinal therapy, dose, duration, etc.), routine assessments, the participating physicians (i.e.general practitioners and internists) are asked to document relevant data related to the budesonide/formoterole therapy in patients with COPD.

This observational non-interventional study is designed to demonstrate the improvement of physical function in COPD patients with exercise-induced dyspnoea on treatment with Spiriva (tiotropium 18 µg capsules) and allows adverse events to be recorded and evaluated.

To investigate coronary heart disease and stroke among American men of Japanese ancestry who were living on the island of Oahu in 1965. Morbidity and mortality surveillance of the original cohort is continuing.

The overall objective of the Center was to develop a scientific data base for the control and prevention of acute and chronic lung injury caused by the inhalation of a variety of agents in the workplace and in the environment. There were two epidemiologic studies. Respiratory Effects of Exposures to Irritant Gases: To collect longitudinal lung function and symptom data in chemical manufacturing workers who were exposed to chemical irritants such as ammonia, chlorine, phosgene, isocyanates, sulphur dioxide, nitrous oxide, formaldehyde, organic acids, hydrochloric acid fluorides, other aldehydes, and acid anhydrides. Workers in the Cotton Textile Industry: To detect and quantitate the risk for the development of chronic obstructive airways disease which occurred in workers exposed to cotton dust in textile manufacturing.

To determine factors, including maternal cigarette smoking and acute respiratory illness, influencing infant lung function at birth and up to five years of age.

To assess the population burden of occupational exposures in the prevalence and progression of chronic obstructive pulmonary disease (COPD).

To perform a genome-wide search for genes affecting two phenotypes related to asthma and chronic obstructive pulmonary disease (COPD) in a Chinese population.

The aim of this study is to collect capnometric (tidal breathing CO2) data using TidalSense's N-Tidal C Data Collector Device. The data collected will be examined for correlation with currently accepted assessment techniques for COPD (spirometry, vital signs and pulse oximetry) and the patient's clinical condition (stable, worsening, improving). The patient numbers and study duration have been determined by power calculations to provide a statistically significant sample size, based on expected number of exacerbations (mild, moderate and severe) from the patient cohort. The data will also be examined to assess the predictive possibility of a non-invasive self-care personal CO2 monitoring device to identify COPD exacerbations.

Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease that causes obstructed airflow from the lung, characterized by chronic cough, dyspnea, and sputum production. Inspiratory muscle weakness has been shown in patients with COPD, and inspiratory muscle training (IMT) is commonly applied to these patients. However, the optimal prescribed intensity of IMT for patients with COPD remains unclear. In healthy adults the accessory muscles would be recruited to assist ventilation with increasing ventilatory demand, but the activation pattern of accessory muscles has not been studied in patients with COPD during loaded condition such as IMT. Therefore, the purpose of this study is to exam diaphragm and sternocleidomastoid muscle activation using surface electromyography during loaded inspiratory muscle tests with intensity of 30% and 50% of maximal inspiratory pressure.

To assess the effectiveness of maintenance treatment of Chronic obstructive pulmonary disease (COPD) with the Long-acting beta2-agonist - long-acting muscarinic antagonists-inhaled corticosteroids (LABA-LAMA-ICS) combination with a LABA-LAMA combination on the risk of COPD exacerbation and the safety on the incidence of community acquired pneumonia.
