Filter by:There is no clinical evidence that face masks are efficient in birch pollen-induced asthma. As the use of face masks has become widespread worldwide to limit the spread of SARS-CoV-2, this study aims to demonstrate the clinical efficacy of medical masks in patients allergic to birch in the same way that clinical trial with drugs.
The goal of this observational study is to assess the response to treatment, in patients 18 years and older diagnosed with severe asthma in whom an IL5/IL5R antagonists was initiated between 2012 and 2020. The main question[s] it aims to answer are: - What is the response rate after one year of treatment with IL5/IL5R antagonists. - What is the response and remission rate after one year of treatment with IL5/IL5R antagonists in subjects who fullfilled the original randomized control trials (RCTs) inclusion criteria compared with those who did not.
Asthma is a worldwide health problem and is one of the most common chronic diseases of childhood in most countries. Symptoms begin before the age of 5 years in 80% of children with asthma, but the diagnosis is not always easy. The National Asthma Education and Prevention Program (NAEPP) expert panel recommends spirometry testing for children over 5 years of age. Spirometry measurements include forced vital capacity (FVC) and the forced expiratory volume in first second (FEV1). Airflow obstruction is defined as FEV1 reduced to less than 80 percent predicted and an FEV1/FVC ratio of less than 0.85 (85 percent). Reference values are based on age, height, sex, and race. Forced expiratory flow between 25 and 75 percent of vital capacity (FEF25-75) less than 65 percent correlates with reversible airflow obstruction in children with normal FEV1 and may be a useful measure in this subgroup. In the spirometry test, FEV1, FVC, FEF 25-75% values are valuable for the follow-up of asthma. While the FEV1/FVC ratio is above 80% in healthy children, it may decrease below 75% in diseases such as asthma. Likewise, FEV1 and FEF can be found to be low in 50-75% of asthma patients. In addition, these values can be used to determine the effectiveness of the inhaler given with the nebulizer given during the attack. Spirometry should be performed before and after administration of a bronchodilator to assess for reversibility (bronchodilator response [BDR]) even in children with a normal baseline FEV1 because many of these children will still have a BDR (both within the normal range and sometimes also supranormal) after treatment. Significant reversibility is indicated by an increase in FEV1 of ≥12 percent from baseline after administration of a short-acting bronchodilator. This definition for BDR positivity was established primarily in adults. An increase in FEV1 of ≥8 percent may be a better definition for BDR in children. Inhaled short-acting beta-2 agonists, particularly albuterol (salbutamol), are the standard emergent treatment for acute asthma exacerbations in all patients based upon adult data. It is recommended to be given every 20 minutes in case of need for repeated doses in mild and moderate asthma attacks. Different types of nebulizers can be used for inhaler therapy; they can convert drugs into vapor form with sound waves, compressed air or by using electrical energy. While compressor nebulizers convert the liquid drug into aerosol form with compressed air, mesh nebulizers convert the drug into aerosol form with the vibrations they create with the help of electrical energy. Mesh nebulizers are more effective than other types of nebulizers, and the amount left in the chamber is less than other models, and it can decompose the drug into smaller particles and reach the more extreme branches of the lung. In our study, the investigators aimed to determine which nebulizer type is more effective by comparing the effects of mesh nebulizer and compressor nebulizer on spirometry test in children presenting with asthma attack. Thus, the investigators planned to find the most comfortable and effective method for patients by determining the appropriate nebulization technique for patients.
this study aimed to compare characters in pulmonary function of patients with cough variant asthma and chronic cough and establish a diagnostic model.
To compare the effects of moderate intensity interval training and sprint interval training on patients having chronic asthma.
Comparison of the new multiple-breath washout method (ndd Medizintechnik Zürich, Trueflow™/Truecheck™) with established methods of lung function diagnostics in patients with idiopathic pulmonary fibrosis, chronic obstructive pulmonary disease, asthma and cardiopulmonary healthy individuals.
The Sponsor is developing the test medicine, AZD4604, as a potential treatment for asthma. Asthma is a common lung condition caused by inflammation (swelling) of the breathing tubes that carry air in and out of the lungs, causing occasional breathing difficulties such as wheezing, shortness of breath, chest tightness and cough. This study in healthy volunteers will explore the following questions. - Does the test medicine cause any important side effects? - What are the blood levels of the test medicine and how quickly does the body get rid of it? - How much of the test medicine gets into the bloodstream? - How does the body break down and get rid of the test medicine? This study will take place at one non-NHS site in Nottingham, and plans to enrol 8 healthy men and women aged 18-65 years who will be involved in both parts of the study.
The aim of this randomized controlled trial is to determine the effectiveness of costovertebral joint mobilization on lung function in asthmatics. By targeting the thoracic region, costovertebral mobilization can play a valuable role in enhancing respiratory function and improving the overall well-being of individuals with respiratory conditions.
The goal of this study was to investigate the effectiveness of three common approaches to upgrading residential mechanical ventilation systems in existing homes for improving asthma-related health outcomes, reducing indoor pollutants of both indoor and outdoor origin, and maintaining adequate environmental conditions and ventilation rates in a cohort of adult asthmatics in existing homes in Chicago, IL.
Objectives: To examine the effect of interactive online education given by peers or adults on anxiety, self-efficacy, quality of life, and disease knowledge and management in adolescents with allergic asthma in the 10-14 age group. Methods: The research was conducted as a randomized controlled study. The study sample consisted of 84 adolescents divided into experimental groups [receiving peer(n=28) or adult(n=28) education] and control(n=28) group. The adolescents in the peer or adults were given online interactive education concerning allergic asthma and the management thereof. The control group received only usual training.Data were collected using an Adolescent Personal Data Form, the State Anxiety Inventory for Children, the Self-Efficacy Scale for Children and Adolescents with Asthma, the Pediatric Asthma Quality of Life Questionnaire, and the Disease Knowledge and Management Questionnaire. Data were collected from the adolescents before (T0) and immediately after education (T1), and after one (T2) and three months (T3). This study is a non-blinded randomized controlled trial. . All screened adolescents with asthma were randomly assigned to one of the three groups: the peer or adults education groups that received a 6 weeks asthma education and a control group that received usual care. The three groups were then followed prospectively immediately, 1, and 3 months after training to evaluate the effectiveness of training compared with usual care.
