Filter by:This is an international Delphi study to consolidate expert consensus on the use of respiratory oscillometry in the management of adult patients with asthma or chronic obstructive pulmonary disease (COPD). The primary objective of the Delphi study is to aid the interpretation of respiratory oscillometry in clinical practice amongst adult patients with asthma or COPD. This will be achieved by obtaining expert consensus on: - Which parameters are used in clinical practice for impulse oscillometry (IOS) and for forced oscillation technique (FOT) devices. - What cut-offs can be used for each parameter to guide clinical practice in the management of adult patients with asthma and COPD. This study is based on the Delphi methodology. The Delphi study will comprise of four rounds, one brainstorming round, to formulate the consensus survey, and three rounds to attempt to obtain consensus. In each round a questionnaire comprising of statements and questions regarding respiratory oscillometry will be sent to participants in the Delphi study electronically using SurveyLet, an online survey platform. Participants will respond anonymously to the survey questions, indicating their level of agreement or disagreement with each statement or question. Participants will be given 4 weeks to complete each round of the Delphi study. Questions and statements will be repeated in subsequent rounds until the predefined level of consensus is met or the maximum number of rounds is achieved (limited to a maximum of 3 rounds). Aggregated results for each statement or question, including distribution of results and consensus status, will be provided to participants after each round to facilitate informed decisions in subsequent rounds.
The goal of this clinical is to compare treatment outcomes between continuous nebulization and intermittent therapy in the management of acute exacerbation of asthma in the emergency department(ED). Participants will random assign to either continuous or intermittent nebulization. In the continuous group, patients receive budesonide, fenoterol, ipratropium bromide, and normal saline continuously for an hour. In the intermittent group, the same medications are administer every 20 minutes for an hour. Measurements include symptom severity, respiratory rate, oxygen saturation, and pulmonary function tests. Primary endpoints are ED stay length, hospital admission, and ED revisit within 48 hours post-discharge. Adverse events are documented.
The overarching goal of this study is to optimize pediatric asthma care and to continuously evaluate variations/innovations of the care (including transformation to remote eHealth care). Primary Objectives within cmRCT cohort: - Provide a framework for multiple randomized (eHealth) interventions for asthmatic children - Generate short- and long-term data on Quality of life (QoL), asthma outcomes (asthma control, lung function), quality of care, self-management capacity, healthcare use, and therapy compliance in a representative secondary care pediatric asthma cohort. Secondary Objectives within cmRCT cohort: - Evaluate current pediatric asthma care at the Pediatric department of Medisch Spectrum Twente, in order to explore possible improvements for the pediatric asthma care. - Compare the short and long-term asthma outcomes between the eHealth care path and the outpatient care path. - Compose patient risk profiles that include both personal, clinical and exposome markers and clinical asthma endpoints (for example clinical admission/exacerbations).
The purpose of the current study is to investigate the usefulness of a Relaxation and Guided Imagery intervention for the reduction of asthmatic symptoms in adults and children whose asthma symptoms are aggravated, or triggered by anxiety. This study will replicate the previous literature to further investigate the impact that a Relaxation and Guided Imagery intervention can have on anxiety and related asthmatic symptoms using a multiple baseline (small sample size) research design. Participants will fill out questionnaires, listen to RGI audio tapes, and provide lung functioning samples by blowing into a spirometer.
This is a randomized clinical trial of metformin among overweight or obese adults with not well-controlled asthma despite maintenance inhaler therapy.
Asthma is a chronic respiratory disease characterised by airway inflammation, bronchoconstriction, and airway hyperresponsiveness. Accurate and reliable assessment of lung function is crucial in diagnosing and monitoring asthma. The forced oscillation technique (FOT) is a non-invasive method that has gained attention in recent years as a valuable tool for evaluating respiratory mechanics in asthma. FOT involves applying small amplitude oscillations at various frequencies to the respiratory system and measuring the resulting pressure and flow responses. These measurements provide valuable insights into the mechanical properties of the airways, including resistance, compliance, and reactance. FOT offers several advantages over traditional spirometry, such as its ability to assess peripheral airway function, sensitivity to small airway abnormalities, and ease of use, particularly in young children or individuals with severe airflow limitation. FOT also allows for assessment of respiratory mechanics in individuals who may struggle with performing spirometry manoeuvres. However, it is unclear whether a change in breathing pattern in patients with obstructive lung disease impacts the assessment of a response to treatment utilising FOT. Several studies have demonstrated a high prevalence of Breathing Pattern Disorders (BPDs) in individuals with asthma. These findings suggest that BPDs may be common in asthma and could contribute to the manifestation and severity of respiratory symptoms. Evidence suggests that BPDs can adversely affect pulmonary function in individuals with asthma. One study demonstrated that children with asthma and dysfunctional breathing exhibited significantly reduced forced expiratory volume in one second (FEV1) compared to asthmatics without BPD. This suggests that abnormal breathing patterns may contribute to airflow limitation in asthma, leading to decreased lung function. We therefore wish to determine the impact of different breathing frequencies on parameters measured using FOT in patients diagnosed with asthma and concomitant obstructive lung function abnormality.
Asthma, a prevalent chronic condition among children and adolescents, substantially impairs their quality of life. In addressing this significant health concern, this study focuses on the potential of a customized exercise rehabilitation program tailored for this young demographic. By employing a randomized controlled trial design, the research aims to divide participants into two distinct groups: one undergoing a personalized exercise regimen and the other receiving standard medical care. The 12-week intervention for the exercise group includes a combination of aerobic activities, strength training, and targeted breathing exercises. The study's primary aim is to rigorously evaluate the impact of this specialized exercise protocol on critical health aspects such as lung function, physical endurance, frequency of asthma attacks, and overall quality of life. The anticipated findings from this research are expected to shed new light on effective asthma management strategies and offer invaluable guidance for clinical practices dedicated to improving health outcomes in young asthma patients.
A phase I clinical research study aimed at determining mechanisms that regulate airway mucosal inflammation in asthma endotypes using intranasal administration of endotoxin (lipopolysaccharide from E. coli) in healthy controls and subjects diagnosed with asthma.
Asthma is defined as a chronic inflammatory disorder of the airways associated with an extreme increase in airway hyperresponsiveness leading to recurrent wheezing, shortness of breath, chest tightness, and coughing attacks. The World Health Organization states that approximately 339 million individuals worldwide have asthma and more than 400 thousand deaths occur due to asthma every year. With effective and sustainable asthma management, it is possible to reduce disease-related complaints, admissions to emergency units and hospitalizations, limit the physiological and psychological effects of the disease, prevent dependence on healthcare professionals and caregivers, increase the quality of life and reduce the mortality of the disease. Patient education, which is within the educational role of professional nurses, is very important in asthma management. The research was planned in a single-center, randomized control group pretest-posttest design. The sample will consist of individuals who applied to the Allergy and Immunology clinic of Sureyyapasa Chest Diseases and Surgery Training and Research Hospital between May 2024 and January 2024, who have been diagnosed with asthma for at least one year and who accept the study [25 intervention group - 25 control group]. Groups will be determined using the random numbers table from the simple random sampling method. A web-based asthma education module will be created in line with the literature, and participants in the intervention group will be given synchronous training in 5 modules. After meeting the individuals in the intervention and control groups and obtaining verbal and written consent, they will be asked to fill out the Patient Information Form, Patient Empowerment Scale and Asthma Control Test prepared via Google Forms. A 30-minute training session will be given to the intervention group every week and there will be short evaluations after each training. When the 5th Module is completed, the intervention group will be asked to fill out the Patient Empowerment Scale and Asthma Control Test Scale. No intervention will be applied to the control group. 5. At the end of the module, the Patient Empowerment Scale and Asthma Control Test will be completed by individuals in the control group. It is thought that web-based asthma education that individuals will receive will positively affect their empowerment levels and increase their disease control.
The goal of this study is to assess and compare the safety and tolerability of salbutamol administered via metered dose inhaler (MDI) containing propellant 1,1-difluoroethane (HFA-152a) or 1,1,1,2-tetrafluoroethane (HFA-134a) in participants aged 12 years and above with asthma.
