Active clinical trials for "Lung Diseases"

This is a randomised controlled experiment in the form of a web based survey study which randomly exposes participants to different forms of public health messages, after which participants will be assessed on their intent to take up the COVID-19 vaccine, recommend the vaccine, and also willingness to propagate the exposed message.

The aim of this real world study is to assess the safety profile of tiotropium/olodaterol (Tio/Olo).

This study conducted an assessment of the influencing factors and correlations that affect self-management behaviors and resilience in the COPD population.

The primary objective is to assess the relation between involuntary and voluntary assessed quadriceps muscle endurance in patients with COPD. We hypothesized a good correlation (>0.8) between the measurements.

This study aims to evaluate the effectiveness of the investigational device (Lunit INSIGHT CXR) in the detection of chest abnormalities.

The PReSent study seeks to clarify the need, develop and test the feasibility and acceptability of a shared decision making intervention to support patients with Chronic Obstructive Pulmonary Disease make decisions about Pulmonary Rehabilitation. The study is split into two parts; (1) an observational study of healthcare professionals implicit attitudes, and (2) a feasibility and acceptability study assessing the value of the newly developed shared decision making intervention including a patient decision aid and decision coaching.

Pseudomonas aeruginosa (PA ) is associated with chronic lung infections in patients with chronic obstructive pulmonary disease (COPD). Commensal flora (microbiota) in lung was recently described using high-throughput sequencing techniques (NGS). PA strains isolated during lung infection episodes of severe COPD patients often show resistance to antibiotics including imipenem that is mainly due to mutation in oprD. In collaboration with Harvard Medical School, the investigators have recently demonstrated that PA OprD mutant shows increased survival (fitness) and its virulence. This bacterium could be more likely to colonize. Colonization by PA OprD mutant could influence the pulmonary microbiota and may worsen disease evolution, particularly in terms of frequency of exacerbations. Our objective is to describe modification of pulmonary microbiota associated with PA colonization, including OprD PA mutant, in severe COPD patients. The investigators will correlate the microbiota modification to medical history. Stable severe COPD patients will be included. Three groups of patients will be sampled: 1) not PA colonized, 2) PA colonized and 3) PA OprD mutant colonized. Medical history will be recorded by the physician as usual and three samples will be performed: 1) sputum, 2) oral wash and 3) water used for oral wash. Regular bacterial culture will be performed and NGS will be performed also to characterize the microbiota.

The investigators will apply xenon-129 (129Xe) and non-contrast enhanced magnetic resonance imaging (MRI) acquisition and analysis methods in 50 subjects aged between 20 and 29 years born pre-term (with and without a diagnosis of bronchopulmonary dysplasia [BPD]) and at term to characterize and probe the relationship between lung structure and function using imaging.

Influence of tuberculosis (TB) on natural course of chronic obstructive lung disease (COPD) has not been well known. This study was designed to investigate the effects of history of TB on the long-term course of COPD.

This study aimed to assess the impact of air filtration on indoor air quality and cardio-pulmonary health in residents living in high outdoor pollution settings in Beijing.
