Asthma is a chronic inflammatory disease of the Airways of recurring character. The obstruction to the airflow carries the short-and long-term consequences that require prophylactic interventions and in emergency many times. The children due to immaturity of the respiratory system associated with the use of steroids suffer structural consequences, as for example, the physical deconditioning that intensifies the symptoms of the disease and affects negatively on the quality of life. Therefore, to set up a physical training program suitable for the paediatric population, using resources to increase adherence to the regular practice of exercises, can be the difference for the reduction of the number of exacerbations, the sensation of Dyspnea and the doses of medication, positively impacting the clinical picture of child asthmatic. The investigators conducted a randomized, blinded in order to evaluate the effects of training with active video game associated with resisted exercise the exercise in inflammatory and functional outcomes resisted in asthmatic children.
Observational cohort study of mid-to-long term survival of patients with acute on chronic obstructive pulmonary disease, analyzed per type of ventilation support provided during first 24 hours in intensive care.
The purpose of this study is to validate the diagnostic accuracy of a novel host-response based diagnostic tool for differentiating between bacterial and viral etiologies in adult patients aged 18 years and older with clinical suspicion of lower respiratory tract infections (LRTI)
The aim of this study is to test whether aspirin improves endothelial function in alpha-1 antitrypsin deficiency-associated lung disease, measured by pulmonary microvascular blood flow on magnetic resonance imaging (MRI) and with apoptotic endothelial microparticles.
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 purpose of this study is to assess the feasibility and the reliability of a telemonitoring system during pulmonary rehabilitation in patients with chronicle obstructive pulmonary disease. The feasibility is assessed using the patient's satisfaction and it ease of use. The reliability of the remote telemonitoring system is assessed comparing the local data (extracted from the monitoring device itself) and the data transmitted through the telemonitoring platform.
The aim of the study is to determine if increased retrograde shear would further deteriorate the already impaired vascular function in severe COPD patients.
Regular physical activity has been found to be important in maintaining health and well-being in people with COPD. The purpose of this study is to test new technology and health coaching aimed to help people with COPD become more physically active in their daily lives.
This study aimed to explore the associations between constitutions of traditional Chinese medicine (TCM) and common disease (CD). A large-scale, community-based, cross-sectional study was performed to investigate the associations. A total of 3748 participants were available for analysis in this study. The assessment of constitution of TCM was based on recommendations of Association Chinese Medicine in China. In this study, the diagnosis of CD was based on self-reported medical history. The associations were analyzed using univariate and multivariable logistic regression (MLR).
