Filter by:The primary objective is to compare the incidence of gastrointestinal AEs in patients treated with IPF, initiating pirfenidone for the first time, according to the type of diet (MUFA vs SFA). Gastrointestinal AEs rates between study groups will be evaluated during the first 16 weeks of pirfenidone treatment.
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.
The main purpose of this clinical trial is to examine the feasibility and effects of tamoxifen in subjects with pulmonary arterial hypertension (PAH). The study will evaluate how well the drug is tolerated, and its impact on functional condition and selected biomarkers. Changes in tricuspid annular plane systolic excursion (TAPSE) and other parameters determined by transthoracic echocardiography will be evaluated as well as changes in additional metrics such as six minute walk test distance, quality of life assessments, and hormone levels.
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.
This study aims at improving the knowledge about resistance training for people with COPD. Resistance training is an important part of pulmonary rehabilitation when the goal is to improve muscular endurance and strength. The study will evaluate the effects and the feasibility of two resistance training programs for people with COPD using a parallel group design. One program will include a larger day-to-day variation (i.e. non-linear periodization) and the progression will be guided by ratings of dyspnea, muscle fatigue, and exertion. The other program will follow the established guidelines for resistance training for people with COPD. The programs will be evaluated for effects regarding muscular endurance, strength, intramuscular adaptions, functional preformance, dyspnea, and health related quality of life. The programs will also be evaluated for feasibility regarding the duration of training sessions, attendance rates, adverse events, and participant satisfaction. The hypothesis is that the non-linear periodization group will have superior effects and that feasibility aspects will be similar between groups.
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.
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.
The main aim of this study is to gain an in-depth knowledge of cardiopulmonary and autonomic health consequences, and related risk factors among people with long-term high-level spinal cord injury. The result of this study will form the basis for further research to improve prevention strategies and risk prediction of cardiopulmonary disorders in people with spinal cord injury.
The aim of this clinical trial is to evaluate, the effects of inspiratory muscle training program in inspiratory muscle function, functional capacity, quality of life, lung function, breathing pattern and chest wall motion in patients with advanced lung disease. Patients were evaluated before the inspiratory muscle training, after 8 weeks of training and at follow-up which was performed 3 months after the end of the intervention.
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.
