Filter by:Background: Stem cell transplants (called hematopoietic stem cell transplantation, or HSCT) are used to treat various diseases. But when the cells for this procedure are donated by someone other than the person who receives the HSCT ( allogeneic HSCT ), the recipient has an increased risk of lung inflammation and scarring. This happens when their immune cells attack healthy lung cells. In this natural history study, researchers will look for the best ways to detect developing lung inflammations earlier after an HSCT. Objective: To see if certain tests can detect early signs of lung inflammation in people after HSCT. Eligibility: People aged 5 to 70 years who will have HSCT as part of another NIH study. Design: Participants will undergo these tests prior to their HSCT. These tests will then be repeated regularly for 2 years: Ultra-low dose computed tomography (CT) scans. Participants will lie on a table that slides through a machine; the machine uses X-rays to get pictures of the inside of the body. This type of scan uses less radiation than normal CT scans. Bronchoscopy with lavage: Participants will be sedated. A flexible tube will be inserted through the mouth and into the airways. Salt water will be squirted into the lung, then sucked out to collect cells and fluids from the lung. Another tube with a camera may be inserted into the airways to take pictures. Blood tests. Blood will be drawn every 2 to 4 weeks. Pulmonary function tests. Participants will breathe into a machine to test their lung function. They will see how far they can walk in 6 minutes.
The goal of this clinical trial is to clinically validate a system for the monitoring of patients' respiratory function and automated oxygen treatment proposal using non-invasive ventilation devices in the treatment of intensive care patients with acute or chronic lung diseases exacerbations. Participants clinical parameters will be monitored and samples will be sent to a clinical laboratory for analysis (arterial blood pressure, heart rate, and respiratory rate will be continuously recorded, and FeO2 and CO2 will be measured with the help of an additional sensor).
Interstitial lung disease (ILD) is a heterogeneous group of diseases consisting of variable amounts of inflammation and fibrosis and a wide variety of acute and chronic pulmonary disorders affecting both the interstitium and lung parenchyma. The use of gamification elements in order to encourage changes in health behaviors such as physical activity appears as an entertaining option by increasing extrinsic motivation in sedentary individuals or in diseases where physical activity is targeted. The aim of this study is to investigate the effectiveness of Nintendo Wii applied in addition to aerobic exercise in patients with ILD on exercise capacity and peripheral muscle strength, symptoms, activity and participation with objective methods, based on evidence.
The primary objective of the study is the evaluation of the effect of hemodiafiltration during ex vivo lung perfusion in marginal donor lungs, and its feasibility. The hypothesis of this study is that this therapy could stabilize perfusate electrolyte composition, remove toxins and waste products, normalize pH levels and prevent edema formation, thereby reconditioning marginal donor lungs for transplantation. The proposed pilot study addresses the unmet clinical needs in several aspects: a) for the first time a homeostatic device will be introduced in EVLP to reach stable perfusate composition; b) the proposed modification of the standard EVLP could lead to longer perfusion times, making elective transplantation possible and setting the base for possible ex vivo lung treatments; c) the ultimate effect of the proposed study is to increase organ availability through reconditioning of marginal donor lungs.
The purpose of this study is to demonstrate that the lung function effect from orally inhaled BGF delivered via HFO propellant is equivalent to the lung function effect from orally inhaled BGF delivered via HFA propellant in participants with COPD. The study duration for each participant will be approximately 15 to 16 weeks and consist of: 1. A screening and placebo run-in period of approximately 2 weeks prior to first dosing 2. Three treatment periods of approximately 4 weeks each (one period for each of 3 study interventions) 3. A final safety follow-up visit via telephone contact approximately 1 to 2 weeks after the final dose administration Participants will be provided with rescue SABA (albuterol or salbutamol) to be used as needed throughout the study. Participants will attend in-clinic study visits approximately weekly during the screening/run-in period (Visits 1, 2, and 3), then every 4 weeks (Visits 4, 5, and 6) to receive take-home study treatment, measure their lung function, and assess their health and safety
Chronic obstructive pulmonary disease (COPD) is a major cause of disability and death worldwide. People with COPD often have cardiovascular diseases (CVDs) that are associated with increased risk for hospitalization and prolonged stay as well as all-cause and CVD-related mortality. Nevertheless, CVDs in patients with COPD are tend to be underestimated in clinical practice. Mechanisms that define the relation between COPD and cardiovascular morbidity include lung hyperinflation, hypoxia, pulmonary hypertension, systemic inflammation and oxidative stress, exacerbation, shared risk factors and COPD phenotypes. Recently, some authors have announced that COPD treatment with dual bronchodilation may not only improve pulmonary function and quality of life, but also have a positive effect on cardiac function in cardiac magnetic resonance imaging (MRI) or two-dimensional cardiac ultrasound for the assessments. The aim of this study is to specify the state of respiratory and cardiovascular systems as well as exercise capacity and quality of life in patients with newly diagnosed moderate-to-severe COPD and to evaluate their changes after short-term treatment with dual bronchodilation. We hypothesize that patients with newly diagnosed COPD and no previous records of cardiac diseases and no apparent signs of heart failure have significantly impaired cardiac autonomic integrity that precedes to increased risk of cardiovascular events. It is believed that cardiac autonomic integrity might significantly improve with dual bronchodilation therapy.
The use of lung ultrasound is instrumental in the evaluation of many chest pathologies and its ability to detect pleuro-pulmonary pathology is widely accepted. However, the use of ultrasound to explore the state of the peripheral lung parenchyma, when the organ is still aerated, is a relatively new application. Horizontal and vertical artifacts are separate and distinct artifacts that can be seen during ultrasound examination of the lungs. While the practical role of lung ultrasound artifacts is accepted to detect and monitor many conditions, further research is needed for the physical interpretation of ultrasound artifacts. These artifacts are diagnostic signs, but we don't fully understand their origin. The artifactual information deriving from the surface acoustic interaction, beyond the pleural line, in the ultrasound images of the normally aerated and non-deflated lung, represents the final result of complex interactions of acoustic waves with a specific three-dimensional structure of the biological tissue. Thus, the umbrella term "vertical artifacts" oversimplifies many physical phenomena associated with a pathological pleural plane. There is growing evidence that vertical artifacts are caused by physiological and pathological changes in the superficial lung parenchyma. Therefore, the need emerges to explore the physical phenomena underlying the artifactual ultrasound information deriving from the surface acoustic interaction of ultrasound with the pleuro-pulmonary structures.
Beyond pulmonary complications, COPD presents with extrapulmonary manifestations including reduced cognitive, cardiovascular, and muscle function. While exercise training is the cornerstone in the non-pharmacological treatment of COPD, there is a need for new exercise training methods. The COPD-HIIT trial intend to investigate the effects and mechanisms of 12 weeks supramaximal high-intensity interval-training (HIIT) compared to moderate intensive continous training (MICT) in people with COPD and matched healthy controls on important clinical outcomes. The trial also intends to compare the effects of 24 months of exercise training (supramaximal HIIT or MICT) to usual care in people with COPD on brain health, cardiorespiratory fitness and muscle power; in people with COPD.
This study will investigate the effect of Budesonide, Glycopyrronium, and Formoterol Fumarate (BGF) metered dose inhaler (MDI) compared with Placebo MDI, and Budesonide and Formoterol Fumarate (BFF) MDI on isotime inspiratory capacity (IC) and exercise endurance time.
The goal of this mixed methods study is to learn about cranial electrotherapy stimulation (CES) using Alpha-Stim AID in anxiety related to breathlessness in advanced lung diseases. The main question[s] it aims to answer are: - Is CES using Alpha-Stim AID acceptable and tolerable as a potential treatment in the management of anxiety in patients who experience breathlessness due to advanced chronic respiratory disease? - What are the key factors that will inform the design of a study to examine its potential clinical effectiveness? Participants will choose whether they want to trial the CES for eight weeks or be in a parallel control group. They will complete daily diaries, questionnaires about anxiety, breathlessness, sleep, quality of life and depression, and an end of study qualitative interview. Researchers will compare those using the CES and those receiving standard care to see if there are any indications of difference in anxiety and other symptoms experienced.
