Filter by:The main reason for this research study is to learn more about some new tests that are being developing for patients with Cystic Fibrosis (CF) to measure changes in the lungs. In this study, the focus will be to learn how stopping Airway Clearance (ACT) and re-starting ACT can affect these tests. These new tests include using a breathable gas called Xenon (Xe) with MRI (magnetic resonance imaging) to improve the pictures of changes in the lungs. The Xenon (Xe) gas that has been treated to have a larger MRI signal (also called hyperpolarized). The other new test is called LCI (Lung Clearance Index) that can measure how well the lungs are working. The MRI machine used in this study has been approved by the U.S. Food and Drug Administration (FDA) and is commercially available for sale in the USA. Hyperpolarized Xe gas is an FDA-approved, inhaled contrast agent for lung ventilation MRI. The new Xe MRI techniques that are being developed and used for this research study are investigational, meaning these new Xe MRI techniques are not FDA approved, but they are similar to FDA-approved techniques that are used clinically at Cincinnati Children's Hospital Medical Center (CCHMC). Xe gas and the new MRI techniques used in this research study have been used for many years in research, including in many research studies conducted at CCHMC like this one.
The goal of this clinical trial is to learn about the safety and efficacy of Pioglitazone in people with Pulmonary Hypertension (PH) due to Chronic Lung Disease (CLD). The main question it aims to answer is: • Whether pioglitazone affects mitochondrial oxygen utilization in patients with PH due to CLD. Participants will be asked to take pioglitazone or placebo once daily for 28 days followed by a washout period of 2 weeks followed by 28 days of the other study drug (participants randomized to placebo followed by pioglitazone or pioglitazone followed by placebo).
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 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.
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.
Background: Some health conditions make breathing difficult and uncomfortable. When this happens every day, it is called chronic breathlessness. Over 3 million people living with heart and lung disease have chronic breathlessness in the UK. Breathlessness is very difficult for patients themselves and their families, resulting in disability and feelings of fear, distress, and isolation. Due a to lack of supportive breathlessness services many patients frequently attend hospital Accident and Emergency (A&E) departments seeking help. Given the on-going challenges faced by the National Health Service (NHS) in the United Kingdom, such as long waiting times, staff shortages, increased demand for services because of the COVID-19 pandemic, there is an urgent need to develop new ways to support those living with chronic breathlessness. One potential solution is to offer support online, as it is estimated that in the UK, 7 out of every 10 people with chronic breathlessness are internet users. With the help of patients and NIHR funding the research team lead by Dr Charles Reilly, developed an online breathlessness supportive website called SELF-BREATHE. SELF-BREATHE provides information and self-management tools such as breathing exercises, that patients can do at home themselves. SELF-BREATHE has been tested as part of its development. SELF-BREATHE is acceptable and valued by patients. But what is unknown is whether SELF-BREATHE improves patients' breathlessness and their life? This is the question this research seeks to answer. Aims 1. To test if using SELF-BREATHE for six-weeks improves patients' breathlessness, their quality of life and whether SELF-BREATHE should be offered within the NHS 2. To see if patients opt to continue to use SELF-BREATHE after six-weeks and what benefits this may have for patients. Methods The research team are undertaking a randomised controlled trial. For this, 246 people living with chronic breathlessness will be recruited in to this study. Each person will be randomly chosen by a computer to continue with their usual care or their usual care plus access to SELF-BREATHE. All study participants will complete questionnaires at the start of the study, thereafter at seven and twelve weeks after randomisation. These questionnaires will ask patients about 1) their breathlessness and its effect on their life and 2) planned and unplanned hospital visits. At the end of the study, we will compare answers to these questionnaires between the two groups at seven and 12 weeks. This will tell if SELF-BREATHE improved patients' breathlessness and reduced their need for unplanned hospital visits e.g., A&E attendances due to breathlessness.
Background: Interstitial lung disease affects the tissues that aid the transfer of oxygen and carbon dioxide between the air and the bloodstream. The disease can cause fibrosis, a thickening and scarring of lung tissue. Fibrosis often continues getting worse, and most people with this disease die in 3 to 5 years. Objective: To test a study drug (hymecromone) in people with interstitial lung disease or lung fibrosis. Eligibility: People aged 18 years and older with interstitial lung disease or lung fibrosis. Design: Participants will have at least 7 clinic visits over 5 months. Participants will have screening and baseline visits. They will have blood tests and tests of their heart function. They will give a sputum sample. Other tests will include: Spirometry: Participants will breathe in and out through a mouthpiece to measure how much air they can hold in their lungs and how hard they can breathe. Diffusion capacity of lungs for carbon monoxide: Participants will breathe in a gas that contains a small amount of carbon monoxide. Then they will breathe through a mouthpiece. This test measures how well oxygen moves from the air into the blood. Resting energy expenditure. Participants will lie still for 30 minutes with a clear dome over their head. This test measures the calories their body burns at rest. 6-minute walk test. Participants will walk at their normal pace for 6 minutes. Their vital signs and blood oxygen levels will be checked. Hymecromone is a tablet taken by mouth. Participants will take 2 tablets every morning and 2 tablets every night for 12 weeks. Tests will be repeated at study visits.
This study aims to i) To characterize the functional status and explore the determinants of functional status decline of people with IlD ii)To determine the measurement properties of functional status instruments in people with Interstitial lung diseases (ILD) iii) To identify the impact of ILD and the participants' perspectives on functional status through interviews iv) Explore the progression of functional status progression in people with ILD and v) Develop a multidimensional index, incorporating functional status parameters, to predict mortality in people with ILD. Patients with ILD will be recruited via the pulmonology services at hospitals, namely from Centro Hospitalar de Vila Nova de Gaia/Espinho (CHVNG/E), Centro Hospitalar do Baixo Vouga (CHBV) and Centro Hospitalar de Entre o Douro e Vouga (CHEDV). Sociodemographic, clinical characteristics (i.e., smoking habits, vital signs and symptoms), anthropometric (i.e., height and weight to compute body mass index) and general clinical data (i.e., medication, oxygen therapy, non-invasive ventilation, acute exacerbations, hospitalizations and number of hospital admissions in the last month and year, length of stay), as well as prior and follow-up spirometric measurements and arterial blood gas will be collected from clinical records for patients' characterization. Mortality and rehospitalizations will be explored during the study period. Peripheral muscle strength, functional status, daily physical activity, self-reported symptoms, functional status, impact of the disease and health-related quality of life. Qualitative data from interviews. The assessments will be conducted at 6 time points: baseline and 1 week after for instrument validation, followed by assessments every 6 months for 2 years. It is expected that: i) Functional status limitations can be comprehensively identified and measured in individuals with ILD. ii) Some measures are valid and reliable indicators of functional status in individuals with ILD. iii) Different profiles of functional status progression will be identified in individuals with ILD, including stable, slow, and fast decline. iv) A multidimensional index incorporating functional status will improve the accuracy of predicting mortality and outperform the predictive ability of the current GAP Index.
This study aims to test the effects of a patient decision aid (PDA) on planning for end-of-life (EOL) care among older adults with COPD. The main questions it aims to answer are: 1. Does a PDA improve the process of a person to make decisions on EOL care? 2. Does a PDA improve the readiness of a person to join advance care planning (ACP) communication? 3. Does a person make an advance directive after using a PDA? Participants in this study will: 1. Be randomly assigned to one of two groups. 2. In the experimental group, participants will receive two 60-minute interactive consultations over four weeks, using a PDA to help clarify values and preferences for future medical care. A guidebook summarising these future care options will be provided. 3. In the control group, participants will receive two 60-minute sessions on lifestyle modification and self-care management over four weeks using a guidebook with coaching. A guidebook summarising general health information will be provided. Researchers will compare the intervention group to the control group to see if the PDA is better at improving the decision-making process on EOL care, the readiness of a person to join ACP communication and the chance to make an advance directive.
Sarcopenia, the loss of muscle mass and strength with ageing, is a prevalent condition in older adults, particularly those with chronic lung diseases like COPD and interstitial lung disease. The condition exacerbates the decline in physical ability, leading to decreased mobility, impaired quality of life, and increased disability. Sarcopenia's prevalence varies across populations, estimated to affect up to 10% of adults over 60 worldwide, with higher rates reported in studies employing consensus definitions of sarcopenia. The prevalence is even higher in patients with chronic lung diseases, reaching up to 26.6%. Sarcopenia's impact on health-related quality of life has been widely investigated. The condition is associated with various comorbidities, including chronic heart failure, obesity, diabetes, and chronic kidney disease, all negatively impacting the quality of life. The proposed study's primary aim is to assess the feasibility of the FACS (finding, assessing, confirming, severity) approach in determining sarcopenia's prevalence in the chronic lung disease population. FACS includes screening, strength measurements, and bioelectrical impedance analysis (BIA) to confirm sarcopenia. The study will also explore potential mechanisms associated with sarcopenia in this population, using proteome and single-cell transcriptome profiles. These multi-omics approaches provide a comprehensive view of the cellular and molecular changes underlying sarcopenia.In particular, the study will evaluate patient acceptance, time efficiency of each test, and recruitment effectiveness. The outcomes will guide the design and execution of subsequent, larger studies and provide preliminary data for power calculation for the full-scale study.
