Active clinical trials for "Lung Diseases"

Purpose: Characterize the depositional attributes of a specialized trans-nasal aerosol delivery device in healthy people using clinical measurements of mucociliary clearance. Procedures (methods): 14% hypertonic saline (HS) aerosol containing the radio tracer Tc99m-sulfur colloid will be delivered via the tPAD and compared to the well characterized PARI LC Star nebulizer (7% HS) using planar gamma scintigraphy (i.e. particle clearance). The fraction of sulfur colloid particles that clear over the ensuing 24 hours with each device will indicate the fraction deposited in conducting airways.

People with chronic obstructive pulmonary disease (COPD) have balance problems and are at risk of falling. New guidelines recommend balance assessment be included in pulmonary rehabilitation (PR) however no specific tests are recommended. Our goal is to determine the best balance test for identifying COPD patients who are at risk of falling. In this study, COPD patients who report balance problems or falling in the last year will participate in a testing session. Balance, balance confidence, lower body strength, exercise tolerance and perceived physical limitations will be assessed. The number of falls over the following year will be recorded using monthly calendars.

The primary objective of this study is to assess the presence of a correlation between the Lung ultrasound score (LUSS) and PaO2/FiO2 in patient presenting with interstitial syndrome (IS) in the ED. The primary end point considers the null hypothesis to be a negative linear distribution for LUSS and PaO2/FiO2 values. Secondary objectives and secondary end points One of the secondary objectives is to assess the correlation between the LUSS and PaCO2 in patient presenting with IS in the ED. The end point of this secondary outcome considers the null hypothesis to be a positive linear distribution for the LUSS and PaCO2 values. Another secondary objective is to determine the influence of the presence of unilateral or bilateral pleural effusion on the correlation between LUSS and PaO2/FiO2. The end point of this secondary outcome considers the null hypothesis to be a negative linear distribution for LUSS and PaO2/FiO in those three sub-groups: absence of pleural effusion group, unilateral pleural effusion group and bilateral pleural effusion group.

Electronic nicotine delivery systems (ENDS/e-cigarettes/vaping) are increasingly popular among teenagers around the world. The safety and potential adverse effects of ENDS in this population are largely unknown. While the aerosol, that users inhale, appears safe under laboratory conditions, there are still open questions, which have not yet been assessed. These cover (a) differences in exposure to chemicals (such as metabolites of Volatile Organic Compounds (VOCs) and metabolites of Polycyclic Aromatic Hydrocarbons (PAHs)) between healthy teenagers using ENDS and healthy teenagers not vaping, (b) effects of exposure to such chemicals on the body (measured by lung health indicators: airway symptoms such as coughing; lung function and lung structure tests; immune response of airway cells exposed to vapor; markers of oxidative stress), and (c) the role of nicotine metabolism. It is unknown which lung health indicator/s is/are most relevant to assess the effect of ENDS on lung health in teenagers. The primary hypothesis of this study is that there will be differences in exposure to chemicals, resulting in more or more severe airway symptoms in vaping teenagers compared to their non-vaping peers. While there might not yet exist any differences regarding lung function or structure, we expect already visible effects of vaping on the local immune response of primary cells isolated from airways in vaping teenagers as compared to non-vaping peers. In this study, participants of the Bern Basel Infant Lung Development (BILD) cohort, a birth cohort of healthy term-born infants and their follow-up, will serve as healthy, non-vaping controls.1 Vaping teenagers will be recruited independently from the BILD study through advertisements and visits to Bernese schools. Both populations combined represent the study population of the e-BILD study. All e-BILD study participants will undergo the same investigations. While these are currently planned for once in a time (so-called cross-sectional design) to compare results from non-vaping BILD study participants to otherwise healthy but vaping teenagers, repeated measures might follow, depending on the findings of the first phase.

The purpose of this research study is to determine the feasibility, acceptability, and evidence for clinical impact of a mobile app-based program called Palliative Care Planner (PCplanner) in addressing needs and promoting advance care planning discussions among patients with idiopathic pulmonary fibrosis and their clinicians.

Home sleep studies - which allow the measurement of breathing while the person sleeps - will be performed on patients with fibrotic interstitial lung disease attending two of the UK's largest respiratory medicine services.The study will investigate at how symptoms, and breathing and exercise tests differ between these two groups after 12 months of study.

A constant load exercise during 10 minutes will be performed in a group of Chronic Obstructive Pulmonary Disease patients, in a basal condition (spontaneous breathing); under noninvasive mask ventilation and with high flow nasal cannula. With the aim of reducing dyspnea, increasing exercise tolerance, and unload respiratory muscles, three exercises will be compared in terms of use of respiratory muscles and neural drive measured with paraesternal electromyography.

For this study, cells will be harvested from the patient from the peripheral blood, isolated and concentrated using proprietary Emcyte™ equipment/centrifugation, and then returned to the patient same day via the peripheral circulation. As circulation occurs, the concentrated cells enter the right heart and are then disseminated into the lungs, becoming trapped in the lung's microcirculation. Here, the cells are believed to produce multiple bioactive factors such as cytokines and anti-inflammatory mediators. Several growth factors are released by activated platelets becoming honing cells for healing within the tissue. The exact long-term mechanism of action of PRP-PC in the lungs remains under investigation. Safety studies have proven that autologous treatment is incredibly safe, largely because of the minimal cell manipulation and the autologous nature of the cells. Prior observational studies in this are have shown strong safety profiles as well as strong efficacy in both COPD and ILD.

The purpose of this study is to describe the design, methodology and evaluation of the preclinical test of Carebot AI CXR software, and to provide evidence that the investigated medical device meets user requirements in accordance with its intended use. Carebot AI CXR is defined as a recommendation system (classification "prediction") based on computer-aided detection. The software can be used in a preclinical deployment at a selected site before interpretation (prioritization, display of all results and heatmaps) or after interpretation (verification of findings) of CXR images, and in accordance with the manufacturer's recommendations. Given this, a retrospective study is performed to test the clinical effectiveness on existing CXRs.

Conduct an in-depth evaluation of autonomic function using a validated tests, assess genetic aspects of autonomic failure, and determine the correlation between of autonomic function failure and other clinical variables in patients with COPD.
