Filter by:Patients undergoing an endobronchial ultrasound and biopsy can experience bleeding during the biopsy. These biopsies are read in real time by pathologists who travel to the endoscopy unit during the procedure. Often, when this happens, the blood contaminates the pathology slides making the slide unreadable. This then requires more biopsies to be performed, thus prolonging the procedure, and increasing anesthesia time. One innovative way to reduce bleeding may be to irrigate the bronchial wall with cold saline, where the biopsy is to be taken, immediately before biopsy, thus causing vasoconstriction and possibly resulting in less blood contamination on the biopsy slides. The current study will evaluate this prophylactic irrigation with saline to control bleeding, thus resulting in a quicker diagnostic result of the biopsies.
Pulmonary rehabilitation (PR) is an effective intervention for reducing hospital readmissions, secondary events, and mortality in patients with respiratory pathologies. The program should not be improved by introducing new subjects such as circadian rhythm.
The goal of this clinical trial is to determine if doxofylline and procaterol are effective in treating patients with stable chronic obstructive pulmonary disease (COPD). It will also assess the safety of both drugs. The main questions it aims to answer are: - Does doxofylline demonstrate a comparable bronchodilator effect to procaterol in COPD participants? - What medical problems do participants experience when taking doxofylline and procaterol?"
The goal of this observational study is to investigate the accuracy of Accuhaler tester, Ellipta tester and Turbutester in patients with chronic obstructive pulmonary disease (COPD). The main question it aims to answer is: • Do Accuhaler tester, Ellipta tester, and Turbutester demonstrate comparable accuracy to the In-check DIAL for assessing inspiratory inhalation force in COPD patients?
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.
