Filter by:The definition of obstructive airway disease is a ratio of the forced expiratory volume in one second (FEV1) to the forced vital capacity (FVC) of less than 0.7, which includes conditions such as chronic obstructive pulmonary disease, asthma, lymphangioleiomyomatosis, and bronchiolitis obliterans syndrome. For example, lung obstruction adversely affects many aspects of a patient's health, such as lung function and exercise capacity. Pulmonary rehabilitation is widely used in patients with obstructive airway disease, and the prescription of pulmonary rehabilitation depends on exercise capacity parameters such as peak oxygen uptake (peak VO2), peak workload, and anaerobic threshold. However, patients often have difficulty achieving training goals due to severe dyspnea during exercise. Dynamic hyperinflation is a common cause of dyspnea during exercise in patients with obstructive airway disease. Investigators aim to alleviate breathlessness by reducing dynamic hyperinflation, making it easier to achieve training goals. Methods to reduce dynamic hyperinflation include pursed lip breathing, reducing breathing rate to prolong expiratory time, using bronchodilators, and undergoing lung volume reduction surgery. Among these methods, reducing breathing rate to prolong expiratory time may be the most feasible, and investigators aim to change the rhythm and pace of breathing by adjusting the pedal rate of cycling exercise. The pedaling rate is typically set at 60 revolutions per minute. The European Respiratory Society recommended a pedal rate range of 40-70 revolutions per minute in 2019. There is still no consensus on the relationship between pedal rate and respiratory rate. This prospective observational study, using a crossover design, aims to investigate the effects of pedal rate during exercise testing on dynamic hyperinflation and exercise capacity in patients with obstructive airway disease.
This study will be a randomized control trial. A total of 68 patients will be recruited and randomly assign to the experimental group or the control group in a 1:1 ratio. Participants in the experimental group will receive a 8-week Ba-duan jin exercise training intervention along with Forced Expiratory Technique at least 3 days a week and 30 minutes a day, while participants in the control group will be only given Forced Expiratory intervention and will be told to maintain their original lifestyle for 8 weeks along with standard COPD treatment.
Chronic obstructive pulmonary disease (COPD) exacerbations are risk factors for disease progression and short-term re- hospitalizations. We propose a randomized controlled trial to evaluate the efficacy of a one-device multiparameter telemonitoring in reducing functional decline, symptoms, and risk of re-hospitalization of patients discharged after hospitalization for exacerbated COPD.
The aim of this observational study is to translate the principle of individualised exercise prescription into the evaluation of daily absolute and relative intensity physical activity. The main questions this study aims to answer are: - Phase 1: What does physical activity (intensity) mean to people with COPD? - Phase 2: Are there differences between time spent in absolute and relative physical activity for people with COPD? Phase 1 Participants will take part in semi-structured interview (30-45 minutes) about living with COPD and perceptions of physical activity and how they perceive intensity. This will also include photovoice and photo-elicitation. Demographic information will be recorded and participants will also complete several respiratory symptom questionnaires. Phase 2: Participants will take part in physical activity testing before and after pulmonary rehabilitation while wearing physical activity monitors. Demographic information will be recorded and participants will also complete several respiratory symptom and physical activity questionnaires. Participants will also wear the physical activity monitors for 8 days after the pre-testing sessions and after their final pulmonary rehabilitation class. Sub-study: Participants will be asked to take images of barriers during physical activity, facilitators during physical activity, feelings during physical activity and types of physical activity they take part in for 8 days after their final pulmonary rehabilitation class. Participants will then take part in a semi-structured interview about the images their have taken while doing physical activity.
Background: Some health conditions make breathing difficult and uncomfortable. When this happens every day, it is called chronic breathlessness. Over 3 million people living with heart and lung disease have chronic breathlessness in the UK. Breathlessness is very difficult for patients themselves and their families, resulting in disability and feelings of fear, distress, and isolation. Due a to lack of supportive breathlessness services many patients frequently attend hospital Accident and Emergency (A&E) departments seeking help. Given the on-going challenges faced by the National Health Service (NHS) in the United Kingdom, such as long waiting times, staff shortages, increased demand for services because of the COVID-19 pandemic, there is an urgent need to develop new ways to support those living with chronic breathlessness. One potential solution is to offer support online, as it is estimated that in the UK, 7 out of every 10 people with chronic breathlessness are internet users. With the help of patients and NIHR funding the research team lead by Dr Charles Reilly, developed an online breathlessness supportive website called SELF-BREATHE. SELF-BREATHE provides information and self-management tools such as breathing exercises, that patients can do at home themselves. SELF-BREATHE has been tested as part of its development. SELF-BREATHE is acceptable and valued by patients. But what is unknown is whether SELF-BREATHE improves patients' breathlessness and their life? This is the question this research seeks to answer. Aims 1. To test if using SELF-BREATHE for six-weeks improves patients' breathlessness, their quality of life and whether SELF-BREATHE should be offered within the NHS 2. To see if patients opt to continue to use SELF-BREATHE after six-weeks and what benefits this may have for patients. Methods The research team are undertaking a randomised controlled trial. For this, 246 people living with chronic breathlessness will be recruited in to this study. Each person will be randomly chosen by a computer to continue with their usual care or their usual care plus access to SELF-BREATHE. All study participants will complete questionnaires at the start of the study, thereafter at seven and twelve weeks after randomisation. These questionnaires will ask patients about 1) their breathlessness and its effect on their life and 2) planned and unplanned hospital visits. At the end of the study, we will compare answers to these questionnaires between the two groups at seven and 12 weeks. This will tell if SELF-BREATHE improved patients' breathlessness and reduced their need for unplanned hospital visits e.g., A&E attendances due to breathlessness.

To evaluate the clinical efficacy and health economic advantages of Lung Replenishing and Kidney Enhancing Formula for the treatment of patients with frequent acute exacerbations in the stabilized phase.
The aim of this research program is to validate frailty measurements as a risk stratification tool to predict deteriorations in patient-reported outcomes, to gain a better understanding of patient preferences for care within varying degrees of frailty, and to assess differences in frailty measurement between patients and their clinicians. This work will provide a foundation in the development of customized interventions for people with COPD and varying degrees of frailty, with the goal of improving quality of life and optimizing health system service delivery for patients and their care givers.
The aim of the ORESTES study is to describe the characteristics of the COPD patients initiating Trixeo (BGF -budesonide/glycopyrronium/formoterol) in Spain and to assess their real-world outcomes up to 12 months afterwards. For that purpose,a descriptive, observational, multi-centre, longitudinal, retrospective cohort study involving ~20 Spanish centres and aiming to include between 500 and 700 patients, has been designed.
The objective of this observational cohort study is to provide comprehensive evaluation and early warning for elderly patients with chronic diseases. The main question it aims to answer is: How to explore effective evaluation methods for diseases in elderly patients based on the coexistence of multiple diseases and high individual heterogeneity? How to explore the key indicators and influencing factors of adverse events in elderly patients.. Participants will be followed up at 1, 3, 6, 9, and 12 months to obtain adverse event information.
