Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

Patients with Chronic Obstructive Pulmonary Disease (COPD) who are admitted to hospital are at high risk of readmission. While therapies have improved and there are evidence-based guidelines to reduce readmissions, there are significant challenges to implementation including 1) identifying all patients with COPD early in admission to ensure evidence-based, high value care is provided and 2) identifying those who are at high risk of readmission in order to effectively target resources. Using machine learning and natural language processing, we want to develop models to 1) identify all patients with COPD exacerbations admitted to hospital and 2) stratify them to distinguish those who are at high risk of readmission b) How will you undertake your work? From Toronto hospitals, we will develop a very large dataset of patient admissions for all medical conditions including exacerbations of COPD from the electronic health record. This data will include both structured data such as age, gender, medications, laboratory values, co-morbidities as well as unstructured data such as discharge summaries and physician notes. Using the dataset, we will train a model through natural language processing and machine learning to be able to identify people admitted with COPD exacerbation and identify those patients who will be at high risk of readmission within 30 days. We will test the ability of these models to determine our predictive accuracies. We will then test these models at other institutions.

The purpose of this study was to determine whether potentiating the cystic fibrosis transmembrane conductance regulator (CFTR) with QBW251 in subjects with COPD would be efficacious with regards to reducing lung and systemic inflammation and bacterial colonization as potential drivers of airway obstruction, airway destruction, remodeling and exacerbations. Furthermore, this study provided supportive data to investigate the relationship of COPD phenotype and the response in small airway structure, function, mucus load and spirometry indices as well as in improvement of overall COPD symptoms and quality of life.

Background: The pulmonary rehabilitation effects on various outcomes of COPD are well known. However, they may be lost over time due to poor adherence to therapy with absence of regular exercise maintenance in long term, disease progression, comorbidities, falls incidence and higher exacerbations frequency. Currently, the main focus is to make the patient more active and ensure the benefits maintenance. However, few studies have been concerned with the aim of to investigate the long-term effect of this intervention and the relationship of the change promoted in important outcomes of the disease with its morbidity and mortality. Design: Non-controlled clinical trial, prospective and longitudinal. Setting: Outpatient pulmonary rehabilitation program in Florianopolis, Brazil Subjects: Patients with COPD (GOLD II-IV). Interventions: Pulmonary rehabilitation program (PRP) based on physical training, conducted over 24 sessions supervised, three times a week, including aerobic training in treadmill and resistance training for upper and lower limbs. Main measures: Before, post-PRP, 6 months post-PRP and 12 months post-PRP will be measured Spirometry or Total Body Plethysmography, Triaxial Accelerometry by Dynaport Activity Monitor, Glittre ADL-Test to evaluated functional capacity and functional performance, Six-Minute Walk Test distance on tracks of 20 and 30 meters, muscle oxygenation variables by NIRS PortaLite®, force platform NeuroCom® SMART Equitest®, Timed Up and Go Test, Berg Balance Scale, Activities-specific Balance Confidence, Falls Efficacy Scale - International - Brasil, London Chest Activity of Daily Living score, Modified Medical Research Council score, Saint George Respiratory Questionnaire score, COPD Assessment Test score and Hospital Anxiety and Depression Scale, Behavioural Regulation in Exercise Questionnaire-2, Basic Psychological Needs in Exercise Scale, General self-efficacy scale, COPD self-efficacy scale, Pulmonary Rehabilitation Adapted Index of Self-Efficacy. The death cases and numbers of exacerbations and hospitalizations will be measured by monthly phone calls after PRP.

Patients with COPD exacerbation usually need respiratory support after extubation. Recently, HHHFNC has been used in both adult and neonates with post-extubation respiratory support. Studies indicate that HHHFNC has seminar efficacy compared to non-invasive positive pressure ventilation and superior than conventional oxygen therapy. There are no clinical data of diaphragm electrical activity and cardiopulmonary function for using HHHFNC and UHFOM as post-extubation respiratory support.

This was an exploratory, randomized, subject- and investigator-blind, placebo-controlled, parallel group, proof-of-mechanism study of multiple oral doses of fevipiprant (QAW039) in chronic obstructive pulmonary disease (COPD) patients with eosinophilia.

The primary objective of this study is to assess the safety and effectiveness of Human Multigene Methylation Detection Kit (Fluorescent PCR Method) for help diagnose lung cancer by comparing with clinical standard method (includes chest CT examination or pathological examination).

This study evaluates frequency of exacerbations, respiratory symptoms, physical exercise intolerance and abnormal lung functions among participants who use IQOS with heatsticks compared to smokers of conventional cigarettes

To evaluate the safety and pharmacokinetics of different dose roflumilast in China COPD patient.

The purpose of this study is to assess the long term safety and efficacy of AeriSeal System treatment administered at up to 4 subsegments during a single treatment session for lung volume reduction in patients with advanced emphysema through 48 weeks after treatment.

The purpose of this study is: 1.- to assess the safety and tolerability of autologous adipose derived stem cells (aADSC) administered intravenously in patients with chronic obstructive pulmonary disease, and 2.- to assess if this therapy results in less decrease of lung function parameters (FEV1, FEV1/FVC and 6 min walking distance) compared with a control baseline of 6 weeks. Patients will be followed up for 12 months after the therapy.
