Pediatric Asthma Trial of Corticosteroid Heterogeneity (PATCH): Trial of Dexamethasone Versus Methylprednisolone for Pediatric Critical Asthma

Acute asthma exacerbation is caused by dysregulated pulmonary inflammatory pathways such that standard treatment includes prompt administration of exogenous systemic corticosteroids (SCs), but there remains an ongoing dialogue among the expert medical community regarding the superiority of specific SCs including dose, frequency of administration, route, and delivery. Regimens are often chosen based on provider preference, and different strategies include once-daily dosing (ODD) dexamethasone (DM) 0.6 mg/kg/dose for 2 days, every 6 hours (q6h) DM 0.25 mg/kg/dose for 2 days, and methylprednisolone (MP) 1 mg/kg/dose every 6 hours for 5-days. To address this knowledge gap, the investigators plan to perform a single-center, phase 2, randomized clinical trial of children 3-17 years of age hospitalized for critical asthma (CA) randomized to one of three regimens above. The study would be powered to evaluate rates of additional prescriptions of SC and also secondarily evaluate quality of life metrics.

What characteristics of patients make them more likely to experience ED boarding? 2. What is the impact of ED boarding on costs of health care? 3. How do high-boarding environments affect the clinical care of all patients in the emergency department, including those that do not board themselves. Data will be secondary in nature, collected in the regular Participants already taking intervention A as part of their regular medical care for RA will answer online survey questions about their joint pain for 5 years.

Breathlessness Perceptions Within Respiratory Diseases

Breathlessness is a complex symptom that results in poor quality of life, increased hospitalisations and increased mortality. Breathlessness is influenced by physiological, psychological and functional factors but these are poorly explored. There are also unexplored phenomenon's such as breathing pattern. Therefore, this study aims to understand the influences of physiology, psychology, function and breathing pattern on health related quality of life in those with a respiratory disease compared to healthy controls. This project is a cross-sectional cohort study including those with a known respiratory disease and experiencing breathlessness, compared to non-breathless healthy controls. The investigators will measure your physiology through spirometry (a breathing test that tells us about their lung function), psychology through questionnaires, function through an exercise test and breathing pattern using opto-electrictronic plethysmography (markers are placed on your chest to see how participants breathe while exercising). This will be conducted over two visits. The investigators will recruit participants from clinics at the University Hospitals of Leicester NHS Trust. The investigators are aiming to recruit 50 participants with a respiratory disease and 25 healthy controls. The results of this study will help us understand breathlessness in more detail in order to be able to develop better treatments.

A Study to Evaluate the Diagnostic Performance of Portable Oscillometry Across Chronic Respiratory Diseases

This is a prospective, multicenter, observational cohort study enrolling approximately 4,000 subjects across about 50 centers, including patients with COPD (confirmed and suspected), asthma (confirmed and suspected), bronchiectasis, interstitial lung disease (ILD), upper airway obstruction (UAO), and healthy controls. Participants will undergo standardized clinical assessments, cough search, FENO, ETCO2, impulse oscillometry, spirometry, and/or bronchodilator test, and/or bronchoprovocation test, and/or diffusion capacity test at a single baseline visit, with no investigational intervention or treatment assignment. The primary objective is to evaluate the diagnostic performance of portable impulse oscillometry in Chronic respiratory diseases and to develop an artificial intelligence diagnostic model for COPD based on oscillometry. The study duration per subject is limited to the screening/baseline visit, with no follow-up visits planned.

Chronic Effects of Photobiomodulation With an LED Vest on Functional Capacity, Inflammatory Markers, and Muscle Perfusion in Children With Asthma

Asthma is a chronic inflammatory disease of the airways that results in tissue remodeling, airflow limitation, and bronchial hyperresponsiveness. This study aims to evaluate the long-term effects of photobiomodulation using an LED vest in the management of pediatric asthma. It is a randomized clinical trial involving children aged 6 to 17 years diagnosed with mild to moderate asthma, divided into two groups: an intervention group (using a vest with active LEDs) and a control group (using the vest turned off, simulating the intervention without light emission). The methodology includes clinical and functional assessments such as spirometry, the Asthma Control Test (ACT), the GINA questionnaire, and the Incremental Step Test (IST), which measures exercise tolerance. Photobiomodulation through LEDs promotes cellular biostimulation without thermal effects, modulating inflammatory processes and optimizing tissue regeneration. It is expected that the LED vest will contribute to improving pulmonary function, enhancing quality of life, and complementing conventional treatments. This project aims to advance the clinical application of photobiomodulation as an accessible and effective therapeutic alternative for pediatric asthma.

A Study of Acupuncture for Treating Asthma

Asthma is a common chronic respiratory disease with a low clinical control rate, highlighting the need for novel therapeutic strategies. Recurrent asthma attacks emotional symptoms, such as anxiety and depression, etc. On the contrary, symptoms such as anxiety and depression worsen asthma control. Acupuncture is commonly applied as an effective traditional Chinese medical therapy for asthma. Acupoints GV14, BL13 and BL12 are adopted for the intervention of asthma. GV20 and GV29 are selected to improve emotional symptoms including depression. Nevertheless, standardized therapeutic regimens of acupuncture for asthma and its concomitant emotional symptoms are still lacking. 180 patients with mild to moderate asthma will be recruited in this multicenter randomized controlled trial, randomly assigned to the true acupuncture group, sham acupuncture group and usual care group. The primary outcome is the score of the Asthma Control Test (ACT). Secondary outcomes include the Hospital Anxiety and Depression Scale (HADS), Asthma Quality of Life Questionnaire (AQLQ), pulmonary function, and fractional exhaled nitric oxide (FeNO). The superiority of combined acupuncture therapy in improving asthma control, relieving negative emotions, and enhancing quality of life is to be verified in this study, with high quality evidence for acupuncture treatment of asthma thereby to be provided.

VR vs Treadmill Exercise in Children With Asthma

This study aims to compare the effects of virtual reality-based aerobic exercise and treadmill-based aerobic exercise on functional capacity, pulmonary function, and clinical outcomes in children with asthma. Participants aged 10-17 years with physician-diagnosed asthma will be randomly assigned to either a virtual reality-based exercise group or a treadmill exercise group. Both groups will undergo supervised exercise training sessions twice a week for 8 weeks. Primary outcome will be the 6-Minute Walk Test. Secondary outcomes include pulmonary function, respiratory muscle strength, asthma control, quality of life, and exercise adherence.

Obstructive Sleep Apnoea and Difficult Asthma (OSADA)

The OSADA (Obstructive Sleep Apnoea in Difficult Asthma) trial is an open-label, randomized control trial investigating the impact of diagnosing and treating obstructive sleep apnoea (OSA) on a asthma control in patients with difficult-to-control asthma. Participants will undergo home-based sleep studies to assess for OSA and are then allocated to one of three arms: 1) Patients with OSA treated with CPAP (intervention group), 2) Patients with OSA not treated for OSA (control group) and 3) Patients without OSA (reference group). The primary objective is to evaluate whether treating OSA improves asthma control, symptom burden, and quality of life compared to untreated OSA and to patients without OSA. Secondary outcomes include exacerbation rates, sleep quality, and healthcare utilization. This trial aims to clarify the contribution of OSA to poor asthma control and the potential benefits of integrated sleep and respiratory care in this complex population.

A Study to Understand the Accuracy of a New Breathing Device Compared to Standard Testing for Asthma and COPD

The diagnosis of either asthma or chronic obstructive pulmonary disease (COPD) is currently based on a combination of symptoms, different lung tests and sometimes a 'trial by treatment'. Both COPD and Asthma tests currently include forced breathing using a test known as spirometry which can be difficult and uncomfortable for people to perform and needs expert interpretation. Asthma can require multiple tests in sequence which can make the process of diagnosis long and inconvenient for patients. In the UK, there have been challenges providing enough testing for COPD and asthma, in part because the tests are challenging to provide in the community to everyone who needs one. The STARDUST study aims to test and develop new ways of diagnosing asthma and COPD that are quick, accurate and easy for patient and healthcare professionals to perform. People who have been referred for routine lung testing will breathe normally in and out into a handheld device called the N-Tidal Handset for 75 seconds. This device measures how the level of carbon dioxide (CO2) changes in the breath as people breath through it. The information gathered on the N-Tidal Handsets, called breath records or capnograms, will not be used to alter the diagnosis of any participants in the study. After the capnograms have been collected, the research team will test 'algorithms' that have been developed using artificial intelligence, to see if they can accurately identify the correct diagnosis. Information collected in the study will also be used to make improvements in these algorithms. If confirmed to be accurate, these algorithms could be used in clinical practice to help healthcare professionals make faster, more accessible and accurate diagnoses, especially in settings like GP clinics in the community where access to specialist tests may be limited.

Somatic Health Screening for Adults in Outpatient Psychiatric Care in Denmark (SomaScreen)

People with severe mental illness have a substantially increased risk of undiagnosed and insufficiently treated somatic disease. Somatic Screening in the Capital Region Mental Health Service in Denmark (SomaScreen) is a service-level intervention implemented in psychiatric outpatient clinics in the Capital Region of Denmark to improve the detection and follow-up of somatic disease among patients with psychotic and affective disorders. This study evaluates whether integrating structured somatic screening into mental health services leads to improved identification and management of somatic disease compared with care as usual. Using a quasi-experimental controlled design with a matched cohort, outcomes among patients exposed to the SomaScreen intervention are compared with those of patients receiving usual care in comparable psychiatric outpatient clinics outside the Capital Region.

Study to Evaluate the Safety, Pharmacology and Efficacy of WIN378 in Adults With Moderate or Severe Asthma

This study is trying to identify the right dose of a long-acting medicine called WIN378 for people with moderate or severe asthma. WIN378 blocks the action of a protein called TSLP which causes inflammation in the lung and may contribute to your asthma control and symptoms. The study will test how doses of WIN378 are handled by your body (pharmacokinetics) and assess the safety of the medicine and will assess markers of asthma inflammation in your breath and in your blood, lung function and asthma control (pharmacodynamics).

Can Astaxanthin Help Manage Asthma in POlluted Areas?

This study will test whether astaxanthin, a naturally occurring antioxidant supplement, can improve lung function, reduce airway inflammation, and improve asthma control in adults with mild-to-moderate asthma. Participants will receive astaxanthin and placebo in random order in a double-blind crossover design. Each treatment period lasts 4 weeks and is separated by a 3-week washout period. The study also measures indoor and personal air pollution exposure to examine whether pollution influences asthma symptoms, airway responsiveness, and response to treatment. Exploratory thoracic bioelectrical impedance spectroscopy will be assessed alongside standard respiratory tests.

Immune Status and Disease Control of Inflammatory Airway Diseases

The goal of this study is to learn how the body's immune system affects disease control in people with different airway inflammatory diseases.We want to understand: 1.Whether specific immune cell patterns in the blood are linked to how severe the disease is or how well it is controlled. Participants will: 1. Answer questions about their health and symptoms. 2. Give blood samples 3. Have lung function tests and other standard check-ups. 4. share sleep study results. We will compare people with airway diseases to healthy volunteers to see how their immune systems differ.

The outcome measurements includes 6 minutes walk test, Asthma Control Test, peak flow rate value, and lung function. All participants have been in routine standard treatment of asthma (medication, education of healthy life style and smoking cessation).

Investigation and Classification of Treatable Traits in Patients With Chronic Airway Diseases

This research study focuses on chronic airway diseases, such as Chronic Obstructive Pulmonary Disease (COPD) and asthma. These conditions make it difficult for patients to breathe, but breathing difficulty (dyspnea) is often perceived very differently. Some patients may feel severe distress with mild breathing problems, while others might not notice significant breathing issues even when lung function is poor. This difference in perception is termed "dyspnea perception." The main goal of this study is to understand how dyspnea perception varies among patients with chronic airway diseases. The investigators aim to determine if patients can be grouped into different subtypes based on the perception of breathing difficulties. The study will also investigate how these subtypes relate to other treatable characteristics, such as blood cell counts, allergy test results, and findings from lung function tests and brain scans. Approximately 800 patients with COPD or asthma and 150 healthy volunteers will participate. Participants will answer questionnaires, undergo lung function tests, provide blood samples, and a subset will undergo a special brain scan (functional MRI). No new treatments will be assigned; instead, these characteristics will be observed and measured over time. It is hoped that this study will help doctors better understand chronic airway diseases and lead to more personalized management strategies for patients in the future.

Multicomponent Breathlessness and Physical Activity Intervention in People With Asthma Using a Digital Platform

Treating breathlessness could help people with asthma have fewer symptoms and be more physically active. People with asthma report that it is important to deal with breathlessness during physical activity programs, but past research hasn't focused on this need. The investigators have developed a multicomponent digitally supported intervention targeting breathlessness and physical inactivity. This study will test whether the multicomponent digital supported intervention will help people with asthma. The main question the study aims to answer is: Does the multicomponent digitally supported intervention improve quality of life? Participants will: * Be allocated to the intervention or usual care. Allocation to either group will be random (like tossing a coin). * Attend study visits to complete an assessment involving questionnaires and measurements * Receive telephone calls to ask questions about health * Be invited to take part in an interview to have a conversation about thoughts on participating in the study * Be asked to provide consent to collect information from Services Australia regarding use of health care services and medications

Research on Disease Control and Mental Health Status of Adolescent Asthma Patients

Background: Currently in China, adolescent asthma care is characterized by both undertreatment and overtreatment. Patients in this age group may exhibit negative emotions toward disease treatment and long-term control. Insufficient disease knowledge, irregular lifestyle habits, and negative attitudes toward the disease can all reduce medication adherence, affect disease control outcomes, and thereby increase the risk of severe chronic respiratory conditions and disease burden in adulthood. Objectives: To assess disease control status in adolescent asthma patients, evaluate the psychological well-being of patients and their family members, and understand patients' self-management skills and readiness for transition to adulthood. Procedures: Eligible participants will complete a series of assessment questionnaires through the Youran Huxi mobile application, including questionnaires on asthma control, physical activity, psychological health, self-management behaviors, and transition readiness. The study period is 12 months; the baseline assessment involves one-time completion of written questionnaires with no interim follow-up visits. The study does not intervene in clinical diagnosis or treatment decisions.

This is a Phase 1 study to learn about the safety and pharmacokinetics of the study drug in patients with asthma and whether the study drug has effect during a respiratory challenge.

Optimizing a Sensor-Enabled mHealth Intervention for Adolescents With Suboptimal Asthma Control

Asthma affects nearly 1 in 10 teenagers in the United States and can seriously impact their health and daily life. Teens are expected to manage their asthma by taking medications correctly and paying attention to symptoms, but this can be hard. Adolescents are still developing the skills needed to manage their thoughts, feelings, and behaviors, and they often receive less help from parents during this time. Because each teen struggles in different ways and at different times, they need support that is personalized and responds to what is happening in the moment. Smartphones offer a promising way to help teens manage asthma well. However, most existing asthma apps do not use the full range of proven behavior-change strategies or adapt to what the teen is actually doing day to day. To address this gap, our team created Responsive Asthma Care for Teens (ReACT)-a system that collects data about each time an adolescent takes or misses a dose of medication and monitors symptoms. ReACT helps teens set goals, get feedback, notice barriers, and practice problem-solving skills. Early testing showed that teens liked ReACT and that it improved the skills needed for better asthma management. In this study, the investigators will pilot test ReACT in a study with 160 teens ages 13-17 who have poorly controlled asthma. Teens will be randomly assigned to use ReACT or a comparison intervention for six months. The comparison intervention provides basic asthma education and a place to log symptoms and medication use-similar to what they might normally receive in standard care. Investigators will look at how well the study procedures work across multiple sites and whether ReACT improves the skills that help teens manage their asthma. The investigators will also explore whether ReACT leads to better asthma control and quality of life. Teens will complete assessments at the start of the study, at three months, and at six months. The investigators will gather information through surveys and objective data such as medication use. By the end of this project, the investigators will know whether the ReACT system and study protocol are feasible and ready for a larger clinical trial, and will have early estimates of how much ReACT may improve asthma outcomes for teens.
