Filter by:Our UH3 clinical trial, "Reducing Asthma Attacks in Disadvantaged School Children with Asthma," seeks broad-scale implementation of our effective school-based approach to improve asthma disparities for children, ages 5-12 years, in low-income communities. The investigators will contextualize dissemination and implementation (D&I) of our Colorado school-based asthma program (Col-SBAP) that reduces asthma exacerbations and missed school days, while also addressing social determinants of health. Our Better Asthma Control for Kids (BACK) Program will evaluate key metrics identified by diverse stakeholders during this dissemination trial in rural and small metropolitan areas of Colorado. Our clinical trial includes two implementation strategies: our standard Col-SBAP, titled BACK-Standard (BACK-S) and an enhanced community-centered approach, titled Back-Enhanced (BACK-E). These two strategies are designed for sustainable delivery by school asthma navigators and school nurses who coordinate with primary care and community resources. The Exploration, Preparation, Implementation, Sustainment (EPIS) D&I framework was applied with community partners during the UG3 planning phase to tailor implementation plans that meet local community needs, resources and priorities (EPIS Phases 1 & 2). BACK-S and BACK-E will be delivered from years 1-3 with data collection for implementation and effectiveness outcomes in 4 Colorado regions. In year 4, the investigators will collect data for sustainment outcomes (EPIS phase 3). The investigators will apply the work from EPIS phases 1-3 to refine our "dissemination playbook" that guides adoption by other school systems (EPIS Phase 4). Our primary implementation hypothesis is: Reach will be greater among students when delivered using the BACK-E arm as compared to BACK-S. Our effectiveness hypothesis is: BACK will be more effective than usual care at reducing asthma exacerbations. The BACK playbook includes training materials and a calculation of return on investment. The investigators are targeting schools with high levels of uncontrolled asthma and asthma associated burden. Our UH3 trial includes partner engagement to ensure BACK is disseminated to diverse geopolitical areas of Colorado with attention to sustainability. Collectively, our approach will accelerate dissemination of BACK nationally to communities experiencing health inequities in pediatric asthma care.
Asthma is characterised by episodic symptoms (attacks) caused by airway inflammation and decreased airflow to the lungs. It affects 10% of the Canadian population and is the most common chronic disease in childhood. Despite its burden and its potential to be life-threatening, establishing the diagnosis takes time due to difficulty in accessing specialised breathing tests. Indeed, the current diagnostic strategy relies on a breathing test (spirometry) and, if non-diagnostic, a subsequent more complicated breathing test conducted in hospitals (a bronchial provocation test). Our dependence on the latter test must be confronted to the bottleneck created by our reliance on it and the difficulty to do these tests in children. Furthermore, within the current framework, people receiving a diagnosis do not know if they have active airway inflammation - a key feature with predicts increased susceptibility to asthma attacks and treatment responsiveness. Our study's goal is to validate clinically accessible and useful diagnostic tests for peoplesuspected to have asthma. Specifically, we are interested in alternative tests that are a) achievable outside the hospital; b) useful markers of airway inflammation/risk c) can identify people at with a higher likelihood of responding to anti-inflammatory therapy. The two tests we are mainly interested in are: - Exhaled nitric oxide (measured with a portable handheld machine) - The blood eosinophil count (obtained on a general blood test) +/- Other tests which we might be able to develop within this cohort (e.g. urine tests)
The aim is to identify the underlying disease mechanisms driving specific asthma phenotypes as well as certain disease outcomes and their relation to impaired indoor air quality. This may also help in underpinning specific target mechanisms in order to personalize and improve current treatment options in childhood asthma and develop more successful prevention strategies. This will be done by combining data from detailed clinical phenotyping with multiple -omics data.
Cough is one of the most reported symptoms, especially associated with respiratory diseases. Additionally, cough contains extremely insightful information regarding the patient's health. It is a symptom full of physiopathological information, which can be extremely helpful in clinical practice. However, cough is not currently used as a clinical biomarker given that: 1. Cough is an extremely subjective symptom for patients (patients can't accurately describe and understand their cough's traits). 2. There is currently no tool available to evaluate cough objectively and thoroughly. As such, there is an unmet medical need: solutions for objective cough monitoring and management. C-mo System is a novel non-invasive medical device, which performs an objective monitoring of the patient's cough for long periods of time. The C-mo System consists of a wearable device (C-mo wearable) and a desktop software (C-mo Medical Platform). C-mo System characterises cough automatically through data collection and processing techniques (automatic classification), and its base outputs include: - Cough frequency (how many times the patient coughs) - Cough intensity (how strong cough's expiratory effort is) - Cough type (if the cough is dry, wet, or laryngeal) - Identification of patterns (associations between cough characteristics and specific events, namely the time of day, body position, physical exercising, and meals). It is extremely important to validate C-mo System in a wide and diverse population, given the use of signal processing algorithms and artificial intelligence. C-mo System's base outputs will allow healthcare professionals to improve significantly the medical care associated with this symptom, namely: - Speed-up and improve the accuracy of the diagnosis of several medical conditions, especially respiratory diseases. C-mo System's ability to objectively monitor cough will allow healthcare professionals to make associations between specific cough patterns and specific medical conditions. - Optimize treatment prescription and monitor their effectiveness. C-mo System's objective assessment of cough will allow healthcare professionals to understand if a given therapy is working as intended. - Objectively monitor chronic disease progression. C-mo System's monitoring of cough will allow healthcare professionals to objectively assess the progression of the patient's cough.
This clinical trial aims to investigate patients with poorly controlled, moderate to severe eosinophilic asthma. The main questions it aims to answer are 1. Could the LTh(αK) intranasal treatment improve the clinical condition of these patients? 2. Could patients self-administrate LTh(αK) via the intranasal route? 3. Is the LTh(αK) at multiple doses safe for asthmatic patients? 4. Participants will be asked to self-administrate two doses per week for a total of 6 weeks (11 doses). A diary on LTh(αK) usage, adverse events, and reliever medication will be recorded.
Randomized stratified controlled clinical study for evaluate the effectiveness of a diet program designed for reduce body weight through standard and innovative products that are a substitute meal for weight management in a reduction diet in obese participants with asthma.
The study will compare salbutamol reversibility of methacholine induced bronchoconstriction between a pressurized metered dose inhaler with a spacer versus nebulizer administration using a vibrating mesh nebulizer.
Neutrophils and eosinophils can have different functions. Depending on their environment, they can be more or less active, with more or less inflammatory activity. Biotherapies can reduce the number of inflammatory cells in the blood and bronchi. However, it is not known whether they have the ability to modify the functions of the remaining cells. The aim of this study is to better understand the functioning of eosinophilic and neutrophil polynuclear drugs involved in the response to biotherapies in severe asthma. The hypothesis is that biotherapies modify the inflammatory functions of polynuclear cells, which would contribute to the effect of the drug on asthma.
To evaluate the pharmacokinetic (PK) characteristics and pharmacological effect of GR2002 injection in Chinese healthy volunteers
This study will evaluate the fluctuations of exhaled breath markers in patients with severe asthma on biologics. In the study, severe asthma patients will be followed up to 16 weeks monitoring lung function and inflammation through non-invasive technologies such as exhaled breath analysis (FeNO, GC-MS and EBC). A control group will be followed up to two weeks with the overall objective to indentify and evaluate the modifcations of markers of inflammation in patient under biologic treatment.
