Filter by:Chronic obstructive pulmonary disease (COPD) is the most common chronic tract disease and the third leading cause of death worldwide. The treatment effect of COPD is poor, and the disease is progressive, resulting in a serious disease burden. The key reason is that early recognition is difficult and the early pathophysiological mechanism is unclear, which leads to the difficulty of early intervention.PRISm is likely to be the precursor stage of COPD, which may provide an important research object for the study of pathophysiological characteristics, inflammation and immunomodulatory mechanisms of early COPD, and may also become a new entry point for early intervention of COPD. This study attempts to establish a PRISm prospective cohort，and collects blood, EBC and urine for analysis of inflammatory factors, metabolomics, proteomics and microbiome, and performs chest HRCT to obtain imaging indicators, and conducts 3-year dynamic follow-up observation to study the evolution characteristics of pulmonary function and the incidence of COPD in the PRISm cohort. To compare the differences in imaging, inflammatory factors, metabolomics, proteomics and microbiome among the three PRISm groups, and establish a risk prediction model for progression to COPD through PRISm. It lays a foundation for understanding the characteristics of COPD at an earlier stage and exploring new early warning indicators.
Primary Objective To investigate if patients hospitalised for older adults with a decreased level of physical function, either related to a chronic condition e.g., COPD, Congestive heart failure, renal failure; infections; frailty and tendency of falling; orthopaedic surgery - after hip fracture will increase their time spent out of bed during hospitalisation and 3 months after discharge through visual feedback and motivational intervention about physical activities from a new mobile technology. Hypothesis Patients hospitalised for medical disease will increase their physical activity level during hospitalisation and 3 months after discharge through visual feedback and motivational intervention from a new mobile technology.
The main objective of this project is to identify mechanisms for lung regeneration in patients with COPD induced by exercise training. The hypothesis is that adjusted exercise training improves disease outcome in these patients by decrease remodelling processes linked to oxidative stress, inflammatory and/or immunological pathways in the lung. Along the way, the investigator also expect to identify (or validate) biomarkers mirroring systemic processes such as reduced inflammation and ameliorating the epithelial barrier in these patients. These events may additionally act as potential targets for interventions. Objectives (i) Evaluate biomarkers for regenerative processes, matrix turnover, stem cell activity and inflammatory patterns in lung tissue biopsies, blood- and urine samples correlated to vital lung parameters and physical capacity, before and after attending an exercise-training program. (ii) Study the effects of exercise training on the pulmonary ventilation/perfusion ratio and quality of life. (iii) Evaluate the relation between pathophysiology in the lung evaluated by CT scan, and systemic response measured by muscle biopsies and biomarkers in blood/urine. (iv) Investigate in vitro cell behaviour and remodelling/regenerative processes altered in COPD patients upon exercise training (aim 1).
This is a multicenter, prospective, observational surveillance enrolling 140 consecutive patients with severe emphysema who are candidates for bronchoscopic lung volume reduction using Zephyr Endobronchial Valve at up to 20 centers across Japan and followed for 12 months.
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.
Chronic obstructive pulmonary disease (COPD) is a very common and chronic lung condition and is a leading cause of morbidity and death. These patients have persistent breathlessness and exercise intolerance, affecting their ability to carry out routine daily tasks. Standard COPD treatments include medicines/puffers as well as participation in a Pulmonary Rehabilitation (PR) program. PR programs are delivered by a diverse team of healthcare experts in exercise and nutrition. It is possible that an emerging nutritional oral supplement could target the muscular dysfunction seen in patients with COPD in part by promoting better working mitochondria, the energy 'engine' of muscle. A series of recently published studies in sedentary adults and in older adults have demonstrated the safety, tolerability, and potential clinical effectiveness of this supplement. In this regard, the investigators plan to lead a large randomized controlled trial (RCT) to test whether oral supplementation in patients with COPD who are also participating in a standard PR program will improve overall exercise performance. The investigators will also test muscle strength, cognition, body composition, and other clinically important outcomes such as quality of life. Lastly, the investigators will use muscle tissue from a subgroup of volunteers to investigate the effect on muscle/mitochondrial structure/function. The focus is actually the critical 'first step' before the larger RCT: a pilot and feasibility study on a smaller number of participants with COPD, as an important proof-of-concept that the larger study can, and should, be conducted.
Observational prospective study to evaluate serum NT-proBNP levels in a population of COPD patients three months after the iniation of triple inhaled formoterol/glycopyrrolate/budesonide therapy.
The randomized controlled trial will involve 30 participants, with Group A receiving GPRM and ACBT, while Group B follows the conventional COPD model that includes ACBT only.Assessments of heart rate, physical fitness, and quality of life will contribute to a nuanced understanding of joint function, informing future COPD treatment paradigms.
