Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

This study examines the implications of providing hospital-level care in rural homes.

This study has two parts. The main purpose of Part 1 of this study will be to examine how safe and effective two doses of SelK2 is on participants with mild asthma. Lung function and inflammatory cell numbers will be measured in response to the administration of an allergen (a compound to which the participant is allergic) into the lungs in the presence or absence of SelK2. Part 2 of this study will examine how safe and effective one dose of SelK2 is on participants with chronic obstructive pulmonary disease (COPD). Lung function and inflammatory cell numbers will be measured in COPD patients in the presence or absence of SelK2. SelK2 may block the movement of key inflammatory cells into the lungs and consequently improve lung function in these two patient populations.

The purpose of this study is to assess the activation patterns of diaphragm and sternocleidomastoid (SCM) muscle during different loaded inspiratory muscle performance in patients with COPD after acute exacerbation. Null hypothesis (H0): There is no significant difference between activation pattern of diaphragm and SCM muscle during different loaded inspiratory muscle performance in patients with COPD after acute exacerbation. Alternative hypothesis (H1): There is significant difference between activation pattern of diaphragm and SCM muscle during different loaded inspiratory muscle performance in patients with COPD after acute exacerbation.

Chronic obstructive pulmonary disease (COPD) is a significant current public health problem, characterized by the presence of limited airflow. However, COPD has important manifestations beyond the lungs, the so-called systemic effects. These included dysfunction of peripheral and respiratory muscles. The growing amount of evidence has shown that patients with COPD also present important deficits in postural balance and consequently, increased risk of falling. As an essential part of the management of COPD, pulmonary rehabilitation (PR) alleviates dyspnea and fatigue, improves exercise tolerance and health-related quality of life, and reduces hospital admissions and mortality for COPD patients. Exercise is the key component of PR, which is composed of exercise assessment and training therapy. Currently, two modalities of therapy have been suggested as complementary to pulmonary rehabilitation: inspiratory muscular training (IMT) and neuromuscular electrical stimulation (NMES). Based on the premise that peripheral and respiratory muscle dysfunction can negatively impact postural control of patients with COPD, and given the importance of balance as a modifiable risk factor for falls, it is important to investigate whether the use of these therapeutic modalities (IMT and/or NMES) is capable of improving the short-term effects of pulmonary rehabilitation and also promoting improved balance.

The goal of this randomized controlled trial is to investigate the effects of elastic tape in individuals with mild to very severe COPD. The main questions it aims to answer are: Does the ET influence on daily life physical activity (DLPA), dyspnea, health status, health-related quality of life (HRQoL), and anxiety and depression symptoms in individuals with COPD? Does the ET modify the perceived barriers to DLPA in individuals with COPD? The protocol lasted 21 days, including seven days of initial assessments and 14 days of intervention. Before baseline assessments, participants were randomly allocated into intervention (Elastic Tape Group, ETG, n=25) or control groups (CG, n=25). The ETG received ETs on the chest wall and abdomen for two consecutive weeks while the CG received instructions about the importance of becoming physical activity. The assessments were performed before and after 14 days of intervention. The ET placement was previously described by Pinto et al. (2020).

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.

Disease severity (moderate to severe) is based on the Global Initiative for Chronic Lung Disease (GOLD) guidelines (GOLD 2 - 3)

Introduction: Chronic obstructive pulmonary disease (COPD) is characterized by airflow obstruction, which is clinically manifested by dyspnea and leads the patient to a vicious cycle of sedentary lifestyle. Pulmonary rehabilitation (PR) is an important therapeutic strategy to break this cycle. Cardiovascular diseases are frequent in patients with (COPD) and are associated with higher mortality. The effects of (PR) on cardiovascular risk factors in patients with (COPD) have been little studied so far. Objectives: To evaluate the effects of pulmonary rehabilitation compared to the control group on cardiovascular risk factors in patients with (COPD). Methods: A randomized clinical trial will be conducted. Patients with (COPD) will be divided into two groups: Group I (GI): group that will be rehabilitated, with 3 weekly sessions, for 8 weeks and Group II (GII): control group, without intervention. In both groups, a baseline evaluation will be performed, which will be repeated after 9 weeks and consists of: clinical and laboratory parameters, endothelial function (FMD) and brachial ankle index (ABI). Outcomes commonly used in the assistance to assess (PR) will also be measured. Expected Results: The study is expected to improve understanding of the impact of (PR) on cardiovascular variables in patients with (COPD).

A randomized controlled trial in which icing and airflow stimulation for reduction of dyspnea in patients of obstructive lung disease was done which is characterized as condition of infection described by constant improvement of perpetual constraint of flow of air that is partially reversible and incorporates chronic bronchitis, emphysema and small airway diseases . The tools used were RR, Spirometry, Saturation, Borg Scale, MRC scale, shuttle walk test and St George's Respiratory Questionnaire (St.GRQ) score. Pulse oximeter measured the saturation levels and respiratory rates were alse observed. Borg scale measured rate of perceived exertion ranges from 6(easy physical activity) and 20(worst activity) and MRC measure dyspnea levels. In St.GRQ score between 1 to 8 is symptoms related and 9 to 17 was activity related.Literature review indicate that icing and airflow stimulation reduce dyspnea in patients of obstructive lung diseases.

Ventilated by a single-limb tubing with PEV caused CO2 rebreathing to COPD patients during exercise with the increasing ventilation. The aim of this study was to evaluate whether CO2 rebreathing could be avoided with the use of the dual-limb circuit, to provide a theoretical basis of more rational clinical application of NIV in the setting of increasing ventilation(eg, after exercise).
