Filter by:Rationale: Objective adherence to inhaled therapy by patients with chronic obstructive pulmonary disease (COPD) has not been reported. Objectives: To objectively quantify adherence to preventer Diskus inhaler therapy by patients with COPD with an electronic audio recording device (INCA). Methods: This was a prospective observational study. On discharge from hospital patients were given a salmeterol/fluticasone inhaler with an INCA device attached. Analysis of this audio quantified the frequency and proficiency of inhaler use.
Chronic obstructive pulmonary disease is a major cause of disability and mortality worldwide. This disease progressively leads to dyspnea and exercise capacity impairment. Pulmonary rehabilitation teaches chronic obstructive pulmonary disease patients to cope effectively with the systemic effects of the disease and improves exercise capacity, dyspnea and quality of life in patients with chronic obstructive pulmonary disease. However, the best training modality remains unknown. Physiological studies highlight the benefit of high intensity endurance training. However, many patients do not tolerate such a training due to ventilatory limitation and dyspnea. Therefore, a strategy to reduce dyspnea would allow a greater physiological muscle solicitation and improvement. Thus, many studies focus on means to increase exercise tolerance in patients with chronic obstructive pulmonary disease. Nasal high flow delivers heated and humidified high flow air (up to 60 L/min) through nasal cannula providing physiological benefits such as positive airway pressure and carbon dioxide washout. It can be used in association with oxygen and offers the advantage to overtake the patient's inspiratory flow, providing a stable inspired fraction of oxygen. Nasal high flow has widely been studied in pediatric and adult intensive care units and seems better than conventional oxygen therapy and as effective as noninvasive ventilation with regards to mortality to treat hypoxemic acute respiratory failure. More recently, nasal-high flow has been shown to improve endurance exercise capacity in patients with chronic obstructive pulmonary disease. However, the underlying physiological mechanisms have not been yet elucidated but may help to optimise the utilization of the device. Therefore, the primary objective of this study is to assess the respiratory physiological effects nasal high-flow during-exercise in stable patients with chronic obstructive pulmonary disease. Secondary objectives are to assess the effects nasal high-flow during-exercise on endurance capacity, respiratory drive, dynamic hyperinflation, cardiorespiratory pattern and muscular metabolism.
The purpose of the clinical study is to compare the effect of hypnosis intervention on the emotional dimension of the dyspnea during a pulmonary rehabilitation program to the pulmonary rehabilitation program alone. This study will determine if the hypnosis intervention will lead to better maintenance of benefits obtained than the original described method.
Patients with COPD who participated in the second rehabilitation program in the Pulmonary Rehabilitation unit will be included in the study. Pulmonary function tests, arterial blood gases, mMRC dyspnea perception, 6-minute walking distance, disease-specific (SGRQ) quality of life and hospital anxiety depression scale values will be compared.
This study aims to describe and measure the effectiveness of partnership-based nursing care for people with Chronic Obstructive Pulmonary Disease (COPD) and their families. Investigators hypothesize that an holistic, inclusive -taking account of the challenge of multi-morbidity and the long-term relationship that patients with COPD and their families have with the nurses along with the open structure of whatever kind of services is needed in each patient-family case, often in interdisciplinary and inter-institutional collaboration- , is beneficial as regards use of healthcare, health characteristics, HRQL, use of inhaler medications, sense of security in care and illness intrusiveness.
Chronic obstructive pulmonary disease (COPD) is a major cause of disability. Individuals with COPD are more likely to spend prolonged periods of time in sedentary behaviour (SB) and less in light physical activity compared to their healthy peers. SB is associated with exercise intolerance, reduced motivation to exercise, lower self-efficacy and more frequent acute exacerbations among people with COPD. To date, there is very limited information regarding behavioural approaches to reduce SB in people with COPD. The aim of this study is to examine the feasibility of a new 4-week theory-informed behaviour change intervention to reduce SB in individuals with COPD.
This study will test the accuracy of an investigational, non-invasive device for measuring heart rate and respiratory rate. The device emits radiowaves that allows it to pick up subtle changes in a person's chest wall, which allows it to calculate the heart rate and respiratory rate. We propose to study whether the device's measurements are accurate and reproducible in patients with chronic obstructive pulmonary disease (COPD) or asthma. The device undergoing study has been evaluated in healthy volunteers, but its accuracy in vital sign monitoring in patients with respiratory conditions has not yet been established. This study will serve as the foundation for additional work to assess the device's accuracy in measuring a patient's overall "work of breathing" or respiratory effort. Future work will examine the device's accuracy in measuring work of breathing in patients having an exacerbation of their underlying respiratory condition. The primary aim of this study will be to assess the validity of heart rate and respiratory rate measurements in patients with either COPD or asthma.
At visit one, after the subject has signed the consent form, subjects will answer questions and have maximum reversibility lung function test to determine if they are eligible to proceed with the study. Once the study team has proven that the subject is eligible to proceed the study team will collect a sputum sample and blood sample to study their cells. At visit two the subjects will undergo a research bronchoscopy at this point the study team will collect more samples including a BAL sample and another blood sample. Three follow up phone calls will be conducted after the procedure to ensure subject safety, the study team will record any symptoms that they are experiencing at that time. Throughout this study the samples will be analyzed to see if a larger subset of COPD patients could benefit from using the drug mepolizumab.
Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death worldwide, and over 90% of COPD-related deaths occurring in low- and middle-income countries (LMICs). Household air pollution (HAP) - from burning solid fuels such as wood, dung, agricultural crop waste, and coal for energy - is the primary risk factor for COPD in these settings. Biomass-related COPD has a distinct histopathology, phenotype and inflammatory profile when compared to tobacco mediated COPD. Despite the high global burden of biomass-related disease, little is known about the effectiveness of pharmacotherapies for biomass-related COPD; to date, no clinical trials have focused specifically on treatment of biomass-related COPD. This study proposes to assess the health impact of biomass-related COPD and test the effectiveness of low dose theophylline compared to standard therapy among adults with biomass-related COPD in Uganda with the aim to assess whether low-dose theophylline improves respiratory symptoms, decreases the inflammatory profile of serum biomarkers and whether administration attenuates the effect of HAP on lung function. The study additionally aims to assess whether low-dose theophylline is a cost-effective intervention based on the incremental cost-effectiveness ratio and a range of willingness to pay thresholds.
The objective is to verify that there is a decrease in the pulsed oxygen saturation with the digital sensor. That is, the drop in oxygen saturation in COPD patients during inhalation is real and not due to an artifact of the measuring tool, because oximeters need a quality pulsatile signal to properly measure oxygen saturation
