Active clinical trials for "Lung Diseases, Obstructive"

Investigators will aim to conduct an observational study in order to assess very thoroughly all patients implanted by Extracorporeal carbon dioxide removal (ECCO2R) in 10 critical care units of Paris and its surburb (APHP, Assistance Publique des hôpitaux de Paris). Secondary objectives will be: to assess efficacy and safety of ECCO2R, to compare the data issue from the registry to others studies assessing the same population and to other centers and to compare the different ECCOR devices in terms of efficacy and adverse events.

Preliminary studies have shown that NPPV can avoid tracheal intubation in 40% to 60% patients who have severe exacerbation of COPD. Recently, large-scale comparative effectiveness research (CER) also found that compared with invasive ventilation, NPPV can reduce mortality rates. But there's no high-quality clinical studies which can confirm this. Therefore, investigators believe that NPPV can avoid intubation in patients with severe exacerbation of COPD in ICU with perfect monitoring conditions and reasonable human resource allocation, in order to reduce IMV-related complications and improve patients' outcomes.

Chronic obstructive pulmonary disease (COPD) has substantial economic and human costs. To minimize these costs high quality guidelines have been developed. However, development of guidelines alone rarely results in changes to practice. One method of integrating guidelines into professional practice is the use of clinical pathways (CPWs). The investigators are working with local stakeholders to develop CPWs for COPD with the aims of improving quality of care and guideline adherence while reducing healthcare utilization. The CPWs will utilize several steps including: standardizing diagnostic training, implementing and unifying common components of chronic disease care, coordinating the provision of education and reconditioning programs, and ensuring disease specific care utilizes and delivers evidence-informed practices. In addition, the investigators have worked to identify evidence-informed strategies for the implementation of the CPWs. Efforts are underway to tailor these implementation strategies for the local context. The investigators will conduct a three-year quantitative health services research project using an interrupted time series (ITS) design in the form of a multiple baseline approach with control groups. The CPW will be implemented in two Saskatchewan health regions (experimental groups) and two health regions will act as controls (control groups). The experimental and control groups will each contain one urban and one rural health region. This project is expected to improve quality of life and reduce healthcare utilization. The project will also provide evidence on the effects of CPWs in both urban and rural settings. If the pathways are found effective the investigators will work with all stakeholders to implement similar CPWs for the remaining health regions in the province.

Pneumonia is a major infectious cause of death worldwide and imposes a considerable burden on healthcare resources. Obstructive lung diseases (COPD and Asthma) are increasingly important causes of morbidity and mortality worldwide. The patients with community-acquired pneumonia (CAP), and acute exacerbations of obstructive lung diseases commonly present with similar signs and symptoms. For antibiotic use, the rapid and accurate differentiation of clinically relevant of bacterial lower respiratory tract infections from other mimics is essential. Sphingosine-1-phosphate (S1P) is a bioactive sphingolipid has both extracellular and intracellular effects in mammalian cells. S1P is involved in many physiological processes including immune responses and endothelial barrier integrity. In term of endothelial barrier integrity, S1P plays a crucial role in protecting lungs from the pulmonary leak and lung injury. Because of the involvement in lung injury, S1P would be the potential biomarker of pneumonia. Based on the above evidence, S1P plays an essential role in the pathobiology of pneumonia was hypothesized.

With the comparative effectiveness research methods and hospital registration study approach, the purpose of this study is to objectively record the methods, efficacy and its influencing factors of COPD commonly used treatment methods/programs (Western medicine, Traditional Chinese Medicine and Integrative Medicine) in the actual medical environment, analysis of application characteristics for the different programs, and provide the basis for its revision and promotion. It is a first registration study for COPD in China.

The aim of this study is to investigate the effects of changes in foot structure on physical activity level, fatigue and quality of life in COPD patients.

Chronic obstructive pulmonary disease (COPD) is a serious but treatable chronic health condition. Optimised management improves symptoms, complications, quality of life and survival. Disease exacerbations, which have adverse outcomes and often trigger hospital admissions, underpin the rising costs of managing COPD (projected increase in the United Kingdom (UK) to £2.3bn by 2030). The costs and care-quality gap of COPD exacerbations, coupled with the global rising prevalence present a major healthcare challenge. This study proposal, which has been developed in partnership with patients, clinicians, enterprise and government representation is to conduct an implementation and effectiveness observational cohort study to establish a continuous and preventative digital health service model for COPD. The implementation proposals comprise: - Establishing a digital resource for high-risk COPD patients which contains symptom diaries (structured patient reported outcome questionnaires), integrates physiology monitoring (FitBit and home NIV therapy data), enables asynchronous communication with clinical team, supports COPD self-management and tracks interaction with the service (for endpoint analyses). Establishing a cloud-based clinical COPD dashboard which will integrate background electronic health record data, core COPD clinical dataset, patient-reported outcomes, physiology and therapy data and patient messaging to provide clinical decision support and practice-efficiencies, enhancing delivery of guideline-based COPD care. Use the acquired dataset to explore feasibility and accuracy of machine-learned predictive modelling risk scores, via cloud-based infrastructure, which will be for future prospective clinical trial. Our primary endpoint for the effectiveness evaluation is number of patients screened and recruited who successfully utilise and engage with this RECEIVER clinical service. The implementation components of the project will be iterated during the study, based on patient and clinical user experience and engagement. Secondary endpoints include a number of specified clinical outcomes, clinical service outcomes, machine-learning supported exploratory analyses, patient-centred outcomes and healthcare cost analyses.

This is a retrospective observational study drawing on data from the Brigham and Women's Home Hospital database. Sociodemographic and clinic data from a training cohort were used to train a machine learning algorithm to predict patient deterioration throughout a patient's admission. This algorithm was then validated in a validation cohort.

Objective The Ultrasonic Cardiac Output Monitor (USCOM) is a non-invasive, quantitative method for measuring and monitoring cardiovascular haemodynamic parameters in patients. The aims of this study are: To investigate whether there is any correlation between haemodynamic parameters and COPD severity. To investigate whether USCOM-derived haemodynamic variables may be used as prognostic indicators of 6-month, 1-year, 3-year and 5-year readmission. To investigate whether USCOM-derived haemodynamic variables may be used as prognostic indicators of 6-month, 1-year, 3-year and 5-year all-cause mortality. Design, Setting and Subjects This prospective observational study will be conducted in the Prince of Wales Hospital in Hong Kong. Interventions Haemodynamic measurements made using the USCOM, and spirometry, will be performed as appropriate on subjects in respiratory clinic, the emergency department, medical wards and on ICU. In order to assess inter-observer variability, a second, blinded operator will repeated 15% of scans.

The main aim of this multicentric 5-year follow-up study is to evaluate for the first time the long-term efficacy and safety (in terms of smoking-related serious diseases requiring hospitalization) of e-cigarette smoking, comparing its health effects with those of traditional cigarette smoking and mixed electronic and traditional cigarette smoking. The study will also permit to evaluate, over a 5-year follow-up, the self-reported quality of life, and the reported adverse events according to current and past smoking habit. Finally, the study will also explore the long-term adherence to e-cigarette smoking and its efficacy of e-cigarettes in reducing and/or quitting traditional cigarette smoking.
