Filter by:The goal of this study is to evaluate the usefulness of hyperpolarized (HP) 129Xe (xenon) gas MRI for regional assessment of lung function in a normal population of children and adults and in adults and also in children with respiratory compromise due to a variety of diseases.
This study aims to assess usual walking speed (4-metre gait speed) and markers of sarcopenia predict mortality in patients with chronic respiratory disease.
A critical need exists for efficient community-based interventions aimed at reduction of environmental exposures relevant to health. Biomass smoke exposures due to residential wood heating are common among rural Native American communities, and such exposures have been associated with respiratory disease in susceptible populations. In many of these communities wood stoves are the most economic and traditionally preferred method of residential heating, but resource scarcity can result in burning of improper wood fuels and corresponding high levels of indoor particulate matter. Community-based participatory research techniques will be used to adapt intervention approaches to meet the cultural context of each participating community. At the community level, investigators will facilitate local development of a tribal agency-led wood bank program ensuring that elderly and/or persons with need have access to dry wood for heating. At the household level, investigators will use a three arm randomized placebo-controlled intervention trial to implement and assess education/outreach on best burn practices (Tx1). The content and delivery strategies of the education intervention will be adapted to each community according to stakeholder input. This educational intervention will be evaluated against an indoor air filtration unit arm (Tx2), as well as a placebo arm (Tx3, sham air filters). Tx3 will be used in comparison with the other two treatment arms to evaluate the penetration and efficacy of the community-level wood bank program. Outcomes will be evaluated with respect to changes in pulmonary function measures and respiratory symptoms and conditions among household elders. The investigators hypothesize that locally-designed education-based interventions at the community and household levels will result in efficacious and sustainable strategies for reducing personal exposures to indoor particulate matter, and lead to respiratory health improvements in elderly Native populations. This study will advance knowledge of cost-effective environmental interventions within two unique Native American communities, and inform sustainable multi-level strategies in similar communities throughout the US to improve respiratory health among at-risk populations.
The purpose of this study is the psychometric validation of a self-administered dyspnea questionnaire, usable in clinical practice in order to assess dyspnea and its impact on patients with chronic respiratory diseases.
The primary objective of the study is to determine the safety of oral ifetroban compared to placebo as measured by a > 20% decrease in FEV1 compared to baseline following a dose of Investigational Medicinal Product (IMP) (Study Day 1 or 2) prior to initiation of the aspirin challenge.
The purpose of this study is to determine whether nutritional support with a complete formula is effective to improve malnutrition and respiratory function in patients with chronic pulmonary disease compared to the standard hospital dietary advise.
Using an adult lung bench model of non invasive ventilation, the aim of the study is to compare an experimental system of breath-synchronized vibrating mesh nebulizer to a conventional vibrating mesh nebulizer during non invasive ventilation in terms of inhaled and lost doses.
The primary objective is to determine the clinical benefit of employing the 23-valent pneumococcal vaccine among US military trainees. Secondary objectives include: - determining the etiology of clinical pneumonia among U.S. military trainees; - comparing the serotype distribution of S. pneumoniae (Sp) isolates recovered from vaccinated and nonvaccinated trainees diagnosed with pneumonia; and - comparing days lost from training due to pneumonia or acute respiratory disease for vaccinated and nonvaccinated subjects.
The purpose of this Phase II study is to assess the safety, reactogenicity and immunogenicity of the investigational Non-typeable Haemophilus influenzae (NTHi) vaccine in patients with moderate and severe persistent airflow obstruction.
The purpose of this trial is to test the hypothesis that a treatment diet low in omega-6 fatty acids and high in omega-3 fatty acids can cause improvement in asthma symptoms, nasal symptoms, and pulmonary function in patients with aspirin-exacerbated respiratory disease (AERD).
