This is a multi-center, prospective, cohort study. A total of 10,000 people aged 40～75 without lung disease will be recruited and followed for 3 years. By measure the rate of decline in forced expiratory volume at one second（FEV1） and baseline inflammatory biomarkers in exhaled breath condensate and peripheral blood, we aim to explore the predictive model for chronic obstructive pulmonary disease（COPD） in China.
Inspiratory muscle training has been an important part of pulmonary rehabilitation program directed at patients with COPD. It can increase respiratory muscle strength, relieve dyspnea ,improve the quality of life in COPD patients. However, there is no uniform standard for the intensity of inspiratory muscle training. By comparing a series of indexes, such as maximal inspiratory pressure, maximal expiratory pressure, degree of dyspnea and exercise capacity before and after the training under different intensity, a large number of literatures have explored the appropriate intensity of inspiratory muscle training. But to date, there are few studies about the effects of different intensity of inspiratory muscle training on respiratory physiological mechanism. It has been shown that inspiratory muscle training may be more beneficial to improve the pulmonary rehabilitation effect of COPD patients with inspiratory muscle weakness. So it is not clear whether there is a difference in respiratory physiology between patients with normal inspiratory muscle strength and those with lower inspiratory muscle strength. Respiratory central drive, as an important physiological index, which can be reflected by minute ventilation volume, mouth pressure, mean inspiratory flow and diaphragm electromyography,is closely related to the symptoms and the severity of the disease.Therefore,the purpose of this study was to investigate the changes of respiratory mechanics and central drive in COPD patients at different inspiratory loads, and at the same loads between patients with and without respiratory muscle weakness.That can provide more evidential evidence for setting up the intensity of inspiratory muscle training.
To establish the feasibility of stopping inhaled steroids and switching or maintaining dual bronchodilation in one visit - in the real world, for people with COPD.
Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease that causes obstructed airflow from the lung, characterized by chronic cough, dyspnea, and sputum production. Inspiratory muscle weakness has been shown in patients with COPD, and inspiratory muscle training (IMT) is commonly applied to these patients. However, the optimal prescribed intensity of IMT for patients with COPD remains unclear. In healthy adults the accessory muscles would be recruited to assist ventilation with increasing ventilatory demand, but the activation pattern of accessory muscles has not been studied in patients with COPD during loaded condition such as IMT. Therefore, the purpose of this study is to exam diaphragm and sternocleidomastoid muscle activation using surface electromyography during loaded inspiratory muscle tests with intensity of 30% and 50% of maximal inspiratory pressure.
In our study, it was aimed to evaluate the effect of inspiratory muscle training on fear of movement due to dyspnea in COPD patients. Participants will be randomly assigned to two groups. Inspiratory muscle training in the training group will be administered at least 5 days a week, 15 minutes twice a day, beginning at 30% of the MIP for 8 weeks. Patients will come to the control once a week, the MIP values will be re-measured and the new training intensity will be determined at 30% of the new value. For the control group, a fixed training session will be given for at least 5 days a week, 15 minutes twice a day, not exceeding 15% of the MIP for 8 weeks.
In our study, we aimed to evaluate the validity and reliability of the Turkish version of the Breathlessness Beliefs Questionnaire-BBQ in our study.
This study compares the effectiveness of two different approaches to advance care planning among older African Americans and older Whites living in the community. The two approaches are a structured approach with an advance care planning conversation led by a trained person using Respecting Choices (First Steps) and a patient-driven approach which includes a Five Wishes advance care planning form written in plain language. The study will determine which approach is more effective at increasing advance care planning within each racial group and reducing differences between the two groups in advance care planning.
Patients suffering chronic hypercapnic respiratory insufficiency (e.g. in chronic obstructive pulmonary disease, obesity hypoventilation syndrome) benefit from home mechanical ventilation. These patients are complex; and the ventilator´s parameters should be set-up according to the underlying disease and particular patient's characteristics. The non-invasive ventilation therapy is mostly titrated while the patient is awake, hence Problems, such as Patient-Ventilator asynchrony, arising while sleeping on the ventilator therapy would remain undetected. Sleep studies, such as polysomnography or polygraphy and transcutaneous carbon dioxide monitoring could be valuable tools to fine-tune the ventilator's settings. This could foster the ventilator´s effectivity and patient satisfaction, thus therapy's adherence. Nevertheless the sleep studies are expensive, time-consuming and not widely available. The aim of this study is to learn the findings of sleep studies when they are performed on stable patients on home mechanical ventilation as part of their routine check-ups. In this context, it will be assessed whether the sleep studies' findings lead to a change (adjustment) of the ventilator´s therapy. Moreover, this study aims to investigate whether the absence of sleep studies would result in missing important events that require an adjustment of therapy. The results of this study could provide information that lead to a more standardized protocol of follow-up checks of patients on home mechanical ventilation in a cost-effective manner.
The prevalence of COPD is high and suppose one of the first public health problem in the world. It has a high morbidity and mortality and healthcare costs. The economic aspect is directly related to hospitalization, accounting for 45-50% of total expenditure of COPD. Patients with frequent exacerbations generate most of the cost. In these patients, there are not standardized treatments or monitoring in a medium or long term, but it seems reasonable that the combination of various interventions (programs self-care, active role of health professionals in consultations, home programs, group visits, establishment action plans for patients, use of communication technologies or social networks) may improve many patient outcomes. The hypothesis of our work will be to introduce telemedicine platform to establish action plans for the patient, recognition of symptoms and exacerbations, treatments for the exacerbations, training material on COPD, smoking and inhalation therapy, establishment of a fast and fluid communication with pulmonologist, with the purpose of responding to various health problems that patients with COPD (exacerbator phenotype or ACO phenotype) may have. We will study the impact of this tool to reduce the rate income or readmission for the patients with COPD, analyzing it from the perspective of cost-effectiveness.
