The main goal of this study is to develop a noninvasive signature for pulmonary vascular remodeling in Group 3 PH patients, using hyperpolarized 129Xe magnetic resonance imaging (129Xe MRI). Such a signature may identify Group 3 PH responders to PAH-specific therapies. PAH's unique 129Xe MRI signature has been shown in previous studies. Past studies have lacked a pathologic "ground truth" correlate of these signatures, which could be provided by comparing them with the pathology of lung explant tissue from patients who have undergone a lung transplant. This signature could be validated in a cohort of patients with Group 3 PH in future studies.
The aim is to understand whether activation of receptors involved in clearance of apoptotic cells will improve efferocytosis in COPD patients in vitro and whether generation of pro-inflammatory cytokines can be decreased in COPD patients.
Patients diagnosed with COPD as a result of hyperinflation adapt to the increased workload through shortening and overactivation of other muscles because of their dual function as muscles of the upper limb and neck motion which makes them limited in function and decreases the range of motion in these joints. Another resultant effect of these changes is the shortness of breath taking place following the inability of patients to perform daily activities. Current research is focusing on the use of Muscle Energy Techniques (METs) for such circumstances. Therefore, this study aims to evaluate whether METs result in an improvement in rib cage mobility which could potentially lead to improvements in pulmonary function and activities of daily of living (ADLs) in a group of patients diagnosed with COPD. If positive results are obtained, such an intervention might provide a possible addition to the evidence-based interventions already available for COPD patients. The result of this intervention may provide physiotherapists with further techniques for use in such patients; ones which will be of benefit to the patients and their quality of life and also to the health services.
The purpose of this pilot study is to assess the feasibility of a brief digital mindfulness-based intervention for COPD patients and its effectiveness regarding the reduction of psychological distress as well as stress.
Chronic obstructive pulmonary disease (COPD) is characterized by irreversible airway obstruction and progressive deterioration of respiratory function. Patients with COPD show a limited exercise tolerance, early fatigability and progressive dyspnea, with important consequences on the ability to sustain even mild efforts and a drastic restriction in the activities of daily living. Muscle dysfunction is a systemic manifestation of COPD that contributes to exertion intolerance in individuals with COPD to the point of compromising fundamental functional activities, such as walking. Previous studies have shown, in fact, that quadriceps strength can be reduced by 20% to 30% in patients with COPD and this value is associated with an increased risk of mortality in patients with lower strength levels. In addition, loss of muscle mass or sarcopenia also occurs with a prevalence of between 8% and 67% in patients with COPD, exacerbating the picture of muscle dysfunction. One of the goals of respiratory rehabilitation is precisely the prevention of muscle dysfunction in patients with COPD. However, rehabilitation programs aimed at maintaining and recovering muscle strength are often lacking in guidance regarding target muscles, duration of sessions, and training intensity, while strength assessment is often limited by the timing and resources associated with the clinical setting in which it takes place. This makes it difficult to determine its short- and long-term effectiveness. Therefore, assessment of muscle function in patients with COPD requires tests that are simple and quick to perform, but equally capable of providing quantitative data referable to a specific characteristic of muscle strength as well as indicative of the patient's overall function. In addition, complementary measurements such as body composition and muscle mass, as well as the development of predictive models and normative values of muscle function could provide additional information on the progression of muscle dysfunction in patients with COPD, allowing rehabilitation intervention to be directed toward recovery of the most compromised functions. Therefore, the aims of this study are: 1) To evaluate the effectiveness of a standard pulmonary rehabilitation program in recovering peripheral muscle dysfunction in patients with COPD. 2) To evaluate the clinical reliability of tests commonly used to measure peripheral muscle function in the rehabilitation setting of patients with COPD.
The main purpose of chronic obstructive pulmonary disease (COPD) rehabilitation applications is to increase the functional capacity of the patients and improve the quality of life in daily living activities (ADL). Therefore, the investigators planned the study to determine the influence of ADL and related factors in severe COPD. GOLD C and D COPD patients admitted to Bezmialem Vakif University Faculty of Health Sciences Department of Physiotherapy and Rehabilitation, Pulmonary Rehabilitation Application and Research Laboratory will be included in this study on a voluntary basis. Individuals who have experienced exacerbations of COPD in the last 6 weeks, have comorbidities affecting ambulation and have cognitive impairment will be excluded. Physical and sociodemographic characteristics of all participants will be recorded. Spirometric measurement will used to evaluate pulmonary functions, London Chest Activities Scale (LCADL) will used to evaluate daily living activities, six minute walking test (6MWT) will used to evaluate functional capacity, and mouth pressure will measured to evaluate respiratory muscle strength. (MIP: maximal inspiratory pressure, MEP: maximal expiratory pressure). Saint George Respiratory Questionnaire (SGRQ) for assessing quality of life, International Physical Activity Questionnaire (IPAQ) for assessing physical activity, COPD Assessment Test (CAT) for symptom assessment, and Hospital Anxiety and Depression Scale (HAD) for anxiety and depression assessment will be applied. SPSS 22.0 package program will be used in statistical analysis. For descriptive statistics, mean ± standard deviation values will be calculated and Pearson correlation test will be used in correlation analysis. p <0.05 will be the level of significance.
Background: Dysphagia is frequently observed in subjects with chronic obstructive pulmonary disease (COPD). But tongue strength has not been investigated yet in COPD subjects. The investigators hypothesized that tongue strength is weaker in COPD subjects compared to normal subjects. Methods: This was a single-centre, observational, and cross-sectional study. Twenty-seven subjects with COPD and twenty-four age-matched control subjects were enrolled in this study. Isometric tongue strength was measured using a device fitted with a disposable oral balloon probe. The investigators also evaluated handgrip strength, gait speed, and appendicular skeletal muscle mass (ASM) to define participants as having sarcopenia. ASM, fat free mass index (FFMI), and skeletal muscle mass index (SMI) were measured by bioelectrical impedance analysis. Gait speed was measured using the 6-meter walking test. The eating assessment test-10 (EAT-10) was used to diagnose dysphagia.
Lung structural abnormalities are complex, time-consuming, and may lack reproducibility to evaluate visually on CT scans. The study's aim is to perform automated recognition of structural abnormalities in CT scans of patients with chronic lung diseases by using dedicated software.
This is a randomised, placebo-controlled, double-blind 3-way crossover study in which PUR1800, or placebo is dosed daily for 14 consecutive days in adult subjects with stable COPD over three discrete TPs. Subjects will be randomised to one of the following 3 treatment sequences: Sequence Period 1 Period 2 Period 3 1. Placebo PUR1800 250 μg PUR1800 500 μg 2. PUR1800 250 μg Placebo PUR1800 500 μg 3. PUR1800 250 μg PUR1800 500 μg Placebo Since this is the first study in humans in which the iSPERSE formulation is being administered, the 3 treatment sequences are designed in order to ensure that the lower dose of PUR1800 (250 μg) is administered prior to the administration of the higher dose of PUR1800 (500 μg).
