Filter by:The main objective of this trial is to compare the exacerbation number over 12 months of follow-up between a group of patients with COPD treated according to standardized management (azithromycin prescribed in the event of severe sputum according to the CASA-Q score , standardized comparator arm) and a similar group in which azithromycin is prescribed based on mucus rheology (experimental arm) or CASA-Q.
Background : Long-term home non-invasive ventilation (NIV) can be proposed as treatment for acute respiratory failure with severe alveolar hypoventilation. The aim of NIV is to correct both daytime and night-time hypoventilation and associated symptoms and to provide the patient with adequate night-time oxygen saturation. The benefits of long-term NIV in the management of chronic obstructive pulmonary disease (COPD) patients in a stable state remain controversial. This highlights the importance of identifying the predictive factors for good compliance to the NIV, defined as a use of more than 4 hours per day. Aim of the study: The main objective is this observational study is to monitor the home NIV compliance over a period of 1 year under real conditions of treatment in patients with COPD newly initiated onto NIV (with telemonitoring or not) in order to specify the predictive criteria for good compliance. The secondary objectives are to assess the evolution of functional respiratory data, NIV parameters and changes in prescription, occurrence of acute exacerbations of COPD, hospitalizations and death, patient outcomes (quality of life and acceptability of NIV). Study design: a cohort of 120 patients with COPD newly initiated onto home-NIV (with telemonitoring or not), either in a stable state or following an acute exacerbation will be enrolled in the study and follow-up over 1 year. Data will be collected by lung specialists and home health care provider teams at 1-month post-initiation of NIV, 6 months and 1 year. The study is conduct in France.
In the UK, field-based walking is prescribed in the pulmonary rehabilitation (PR) setting as a convenient, less resource-intensive, and highly responsive exercise modality in COPD patients. However, endurance time during the implementation of field-based walking protocols, such as the endurance shuttle walking (ESW) protocol, is limited to only a few minutes secondary to intense exertional symptoms. It therefore seems sensible to develop an intermittent field-based walking protocol that would prolong endurance time and walking distance compared to the commonly implemented in the PR setting continuous ESW protocol. The aim of this study is three-fold: 1) to identify whether an intermittent shuttle walking protocol significantly prolongs walking distance compared to the widely implemented continuous ESW protocol in the PR setting in patients with advanced COPD; 2) to investigate the test re-test reliability of the distance walked during the intermittent shuttle walking protocol; and 3) to explore patients' and health care professionals' experiences of implementing the intermittent walking protocol and the perceived factors affecting the implementation of these protocols in the PR setting. The study hypothesis is that the intermittent shuttle walking protocol would be associated with lower dynamic hyperinflation and breathlessness, thereby facilitating an increase in walking distance compared to the continuous ESW protocol. The same group of patients with advanced COPD will initially perform an incremental shuttle walk test (ISWT) (visit 1) to establish peak walking speed and subsequently patients will perform the continuous ESW protocol (visit 2) at a walking speed corresponding to 85% of peak walking speed to the limit of tolerance. On two additional visits (visits 3 and 4) patients will perform two intermittent shuttle walking protocols to the limit of tolerance by alternating 1-min walking bouts at a walking speed corresponding to 85% peak walking speed (equivalent to the ESW protocol) with 1-min rest periods in between walking bouts to establish the reproducibility of this protocol. Focus group interviews with patients and healthcare professionals will be conducted to explore perceptions of undertaking and implementing, respectively the intermittent walking protocol.
An open access study that will define and collect digital measures of coughing in multiple populations and public spaces using various means of audio data collection.
It has been reported that nearly half of the patients who are hospitalized for Covid-19 pneumonia have on admission old age or comorbidities. In particular, hypertension was present in 30% of the cases, diabetes in 19%, coronary heart disease in 8% and chronic obstructive lung disease in 3% of the patients. Amazingly, in the two major studies published in the Lancet (Zhou F et al Lancet 2020) and in the New England Journal of Medicine (Guan W et al 2020), the weight of the subjects as well their body mass index (BMI) were omitted. However, obesity, alone or in association with diabetes, can be a major predisposition factor for Covid-19 infection. The primary end-point of our prospective, observational study is to assess the recovery rate in patients with diagnosis of Covid-19 pneumonia. Among the other secondary end-points, we intend to find the predictors of the time to clinical improvement or hospital discharge in patients affected by Covid-19 pneumonia.
The purpose of this study is to investigate the anti-viral effects of low-dose AZM treatment in patients with asthma and COPD with an exacerbation history. The investigators expect that long-term treatment with low dose AZM modulates the immune response to viral infections, with an increased interferon release, in patients with asthma and COPD with an exacerbation history. In addition, the investigators expect a decrease in inflammatory cells and mediators, and changes in bacteria, measured in samples from the lungs. Half of the participants will receive azithromycin on top of their regular asthma/COPD treatment, while the other half will receive placebo on top of their regular asthma/COPD treatment.
The purpose of this study is to assess the activation patterns of diaphragm and sternocleidomastoid (SCM) muscle during different loaded inspiratory muscle performance in patients with COPD after acute exacerbation. Null hypothesis (H0): There is no significant difference between activation pattern of diaphragm and SCM muscle during different loaded inspiratory muscle performance in patients with COPD after acute exacerbation. Alternative hypothesis (H1): There is significant difference between activation pattern of diaphragm and SCM muscle during different loaded inspiratory muscle performance in patients with COPD after acute exacerbation.
This project aims to implement a health prevention program for smokers or former smokers including early detection of lung cancer, cardiovascular disease (CVD) and chronic obstructive pulmonary disease (COPD). The clinical activity is completed by a pre-clinical evaluation of molecular bio-markers of early diagnosis of these diseases, with the aim of strengthening the sensitivity and specificity of the screening program. The project also includes a cost-effectiveness assessment to validate the feasibility of the program. Since lung cancer, CVD and COPD are among the deadliest smoking-related pathologies, the program includes actions aimed at raising awareness among primary care physicians, increasing the smoking cessation rate of participating subjects to improve quality of life.
Patients with COPD will be entered. Participants will be randomized to one of three study arms: Arm 1: meditation; Arm 2: relaxation; Arm 3: Control. Hypothesis: Progressive muscle relaxation and mindfulness meditation will decrease severity of dyspnea, fatigue and care dependency.
Guidelines development, their implementation and the physicians' adherence may have an impact on the occurrence of Chronic Obstructive Pulmonary Disease (COPD) exacerbations and patient's quality of life. We have developed an educational program based on a checklist to assist general practitioners in managing COPD patients. The results of this trial based on electronic health records from BIG DATA databases, such as the electronic health record (EHR) of patients from the National Health Found, associated with checklist, will be directly applicable to primary care in Poland and add new data to the growing body of evidence on interventions to improve chronic illness care and patient's quality of life.
