Filter by:RATIONALE: In asthmatic subjects, smoking can lead to several changes in disease characterictics. in smokers of more than 20 pack-years, chronic obstructive pulmonary disease (COPD) can be associated with asthma, also called asthma-COPD overlap syndrome (ACOS). Increasing data support the concept that ACOS is a clinical entity. However, this should be further studied in order to better target therapy. AIM: The objective of this study is to evaluate the comparative features of ACOS METHODS: This will be a descriptive study comparing the features of the ACOS with the features of asthmatic subjects with an incomplete reversibility of airway obstruction (IRAO).The study will be done over 1 or 2 visits (within a week interval), according to subjects' availability. The visit will include completion of different questionnaires (asthma control asthma quality of life, medical history, exacerbations, etc.), a thoracic examination, allergy skin-prick tests, spirometry and bronchodilator response, lung volumes and compliance measurements, exhaled nitric oxide measurement, blood sampling and a sputum induction.
Exercise training as part of Pulmonary Rehabilitation (PR) has been shown conclusively to improve breathlessness,quality of life and exercise capacity for people with COPD. However generally PR is delivered in a 'one size fits all' approach without considering different aspects of an individual's disease. It is hypothesised that a more personalised approach to PR may yield even better results. However to design a personalised programme of PR we need a better understanding of how different people with COPD respond to different possible exercise training modalities. This study will therefore comprehensively characterise a group of patients and then ask them to complete 3 weeks of exercise training in one of four modalitiesÍž conventional cycling, eccentric cycling, one-legged cycling and resistance training. The aim is not to prove which type of training is more effective but to develop an idea of which groups of patients would benefit from which type of training. Baseline measures would be designed to fully understand how an individual responds to exercise and would therefore be comprised of a variety of endurance tests, strength tests, questionnaires, and measurements of lung capacity and body composition. This is to give as much information as possible to identify different responses to exercise.
In this study, a system will be developed to guide patients with chronic obstructive pulmonary disease (COPD) to complete a mindful breathing practice at home. COPD is the third leading cause of death in the United States and no cure exists. Shortness of breath is the most common disabling symptom. Pursed lips breathing is a type of breathing practice that has demonstrated effectiveness for patients with COPD. It requires practice to maintain and there is currently no home system to provide the needed feedback and support to maintain PLB. Additionally, syncing breathing and heart rate variation offers patients additional benefits. The proposed project explores the use of biofeedback to guide COPD patients in a breathing practice and to provide data for health coaching to monitor and support the practice.
The aim of this study is to evaluate the impact of air pollution on the occurrence and clinical course of chronic respiratory diseases, and discover new biomarkers from various devices such as CT images that can indicate the process and amount of lung damage caused by air pollution. Accordingly, the investigators have designed an prospective cohort with enrollment of normal people and patients with chronic respiratory diseases of three different categories (chronic obstructive pulmonary disease, asthma, idiopathic pulmonary fibrosis). Participants will be followed up for a period of one year, with evaluation of the clinical course of the respiratory disease and exposure to air pollution.
Clinical objectives: estimate the common effect of the EfiKroniK physical exercise program for people with a set of Chronic diseases (solid cancers, hematological, schizophrenia and COPD), expressed in terms of functional capacity, quality of life and others results, regarding the standardized intervention of healthy habits 'Prescribe Healthy Living 'PVS. Implementation objectives: describe the adherence, continuity, adequacy and usefulness of EfiKroniK perceived by patients and professionals, with the purpose of designing implementation strategies, which will be evaluated in future trials. Design: clinical trial and implementation, pragmatic and randomized to two groups stratified by pathology, followed for 12 m. Participants: 370 patients diagnosed with solid cancers, hematological cancers, schizophrenia and COPD, in the most advanced stages. Scope: Hospital de Cruces, Basque Country University, Primary Care Research Unit of Bizkaia. Intervention: personalized exercise program for patients, supervised during 3 months by nursing in primary and autonomous care afterwards, with support from community resources. Reference group: PVS program, of proven effectiveness for the promotion of physical activity, diet and smoking cessation. Measurements: main measure of results: functional capacity at 3 months (6-minute test and submaximal running / running tests at foot to determine the speed of lactate thresholds) and quality of life at 6 and 12 months (SF-36 and specific questionnaires by pathology). Secondary variable results: physical and psychic symptomatology, biological markers, physical form and survival. Analysis: The common effect of the exercise will be estimated by comparing both groups by intention to treat, by means of analysis of the covariance of mixed effects for the changes observed at 3, 6 and 12 months adjusted for the baseline and possible confounders. Previously, a possible interaction effect between the pathology group and the effect of the intervention will be ruled out. The cost-effectiveness and cost-utility reasons.
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.
Home non-invasive ventilators are daily used by patients with chronic respiratory failure. There are frequently used with warming and humidifying systems. These systems need to be cared for and frequently washed by the patient. The aim of this study is to evaluate if the humidifying system of home ventilators are colonized by microbiological germs.
This Dietary Intervention is being done to evaluate the feasibility of a food voucher program and dietary counseling to increase consumption of healthy fatty acids (omega-3) in individuals with Chronic Obstructive Pulmonary Disease (COPD).
Better understanding of the specificities of the vaccine response in patients with COPD
Oxygen therapy is a cornerstone in treating patients with severe chronic obstructive pulmonary disease. Usually, oxygen supplementation is delivered using constant-flow rates. Varying oxygenation levels may occur throughout patients´ changing activity. There is some evidence available that an auto-regulating oxygen flow system (FreeO2), which adjusts the oxygen flow automatically to prevent desoxygenation could be beneficial in comparison to a constant oxygen dose of 2 liter/min during walking. However, these possible benefits are unknown if the FreeO2 is compared to a constant oxygen dose according to the individual prescription. Therefore, the primary aim of this study is to investigate the effects of auto-regulated oxygen flow rates compared to constant oxygen flow rates as prescribed according to international guidelines on walking capacity in patients with COPD.
