Wearable Electronic Breath Sound Sensing Device

This study will assess the ability of a wearable stethoscope to monitor wheezing in high-risk asthma patients admitted at Children's Healthcare of Atlanta. This study is important to assist in the health management of patients with chronic lung diseases that can experience exacerbations leading to their health worsening and requiring hospitalization. The population that will be approached for this study will include 10 pediatric subjects hospitalized at Children's Healthcare of Atlanta for an asthma-related exacerbation. Participants will wear the patches for up to 8 hours on their chest and back wall from their date of consent until their hospital discharge. This may range from the participant taking part in 1 to 14 visits that could last up to 8 hours.

Boosting Referrals to Asthma Specialists for Patients Seen at the Emergency Room for an Asthma Exacerbation

This study is testing a new way to help adults with asthma get follow up care after an emergency room (ER) visit for an asthma attack. Many people who come to the ER for asthma never see an asthma specialist afterward, even though specialists can offer treatments such as advanced inhalers or biologic medicines that may prevent future attacks. The study will compare two approaches. One group will receive a telehealth appointment with an asthma specialist that is scheduled for them before they leave the ER. The other group will receive the usual care, which typically includes a standard referral but no scheduled appointment. All participants will be offered a prescription for standard controller medication at discharge. The main question the study aims to answer is whether arranging a telehealth visit directly from the ER increases the number of patients who complete a follow up appointment with an asthma specialist within three months. The study will also look at whether this approach improves asthma control, reduces repeat ER visits, and helps patients better understand and use their asthma medications. This research may help identify a practical way to improve access to asthma specialists and reduce the burden of asthma for patients who frequently rely on emergency care.

Remote Monitoring of Asthma in Children and Young People

The objective of this study is to determine whether healthcare data and remotely collected patient data can accurately predict asthma attacks in children and young people aged 5-17 years. The main outcome is: when using this new system, is there a reduction in asthma attacks compared with a historic average. The whole population of children and young people with asthma will have routine healthcare data monitored, with a subset of people with high risk asthma asked to participate in a more detail study involving remotely monitored data.

Cost Effective Air Filtration Intervention in Low-Income Housing to Reduce Asthma Morbidity

This project will investigate the effectiveness of HEPA air cleaners in reducing indoor air pollution and improving asthma morbidity in children living in East Harlem, New York City (NYC). The study will be conducted over a 2-year period. Columbia University and Little Sisters of the Assumption Family Health Service (LSAFHS) will conduct an intervention study to evaluate the efficacy of using a cost-effective high-capacity high efficiency particulate air (HEPA) filter air cleaner to reduce airborne particulate matter (PM) in the homes of children with asthma and to reduce their asthma morbidity. The study will take place in East Harlem, a low-income neighborhood with high asthma prevalence. It will build on findings from prior Housing and Urban Development Lead and Healthy Homes Technical Studies (HUD LHHTS)-funded research, the experience of LSAFHS installing air cleaners in the homes of asthmatic children, and recent findings demonstrating the effectiveness of home air cleaners in reducing asthma morbidity. The investigators hypothesize that the cost-effective single air cleaner will substantially reduce PM exposure in the homes of asthmatic children and reduce airway inflammation and asthma morbidity. This study will use cutting-edge air sampling technology to continuously quantify and characterize indoor air pollutants in the home for one year, verify and incentivize compliance, and conduct repeated exhaled nitric oxide and pulmonary function tests before and throughout the year after the intervention. This cost-effective intervention can be easily and quickly implemented in homes in low-income, urban communities and easily transferred between homes if families move.

The Effect of Asthma Flare-up Clinic After Exacerbation

The goal of this interventional study is to examine the effect of asthma flare-up clinic follow-up in adult subjects after an asthma flare-up. This study aim to answer the following questions: 1. Does a follow-up in a flare-up clinic improves disease outcomes? 2. Does a follow-up in a flare-up clinic improves disease management? Participants in the intervention group will take part in a structured follow-up at the asthma flare-up clinic at three time points. Each visit will include questionnaires, pulmonologist examination and consultation, laboratory tests and spirometry. The control group will undergo phone-call follow-up with a research coordinator in similar time frames as the intervention. Researchers will compare the two groups to see if the clinic follow-up affects the study outcomes.

Individualizing Treatment for Asthma in Primary Care (Full Study)

While asthma therapy is becoming more individualized based on asthma phenotypes, more research is needed to tailor newer therapies to individuals. Inhaled corticosteroid (ICS) medications are the foundation of care for all individuals with persistent asthma. But ICS use is not without possible long term side effects. This study will compare two currently available approaches to reduce AEX in primary care patients: (1) use of inhaled corticosteroids (ICS) as part of rescue therapy, also known as MART (Maintenance And Reliever Therapy) or PARTICS (Patient Activated Reliever Trigger Inhaled Corticosteriods) therapy - either of these therapies will be called Rescue-Inhaled Corticosteroids or R-ICS pronounced "Ricks," and (2) use of azithromycin (AZ) as a preventive therapy. These treatments will be studied both individually and in combination.

A Study to Assess the Effect of Dexpramipexole in Adolescents and Adults With Eosinophilic Asthma

The purpose of this study is to evaluate dexpramipexole as an add-on oral therapy in participants with inadequately controlled eosinophilic asthma to evaluate improvements in lung function, asthma control, and quality of life. In addition, the study will further evaluate the safety and tolerability of dexpramipexole in participants with eosinophilic asthma.

Phenotyping and Classifying Asthma Exacerbations

An observational study in patients between 12 and 70 years old with an acute asthma exacerbation, to determine the relation between phenotypical characteristics and the treatment response.

Nebulized Ketamine Plus Standard Care vs. Standard Care Alone in Moderate to Severe Asthma Exacerbations

The goal of this clinical trial is to learn if nebulized ketamine helps treat moderate to severe asthma attacks in adults in the emergency department. It will also learn about the safety of ketamine when inhaled through a nebulizer. The main questions it aims to answer are: * Does nebulized ketamine improve breathing more than standard treatment alone? * What side effects, if any, do participants experience after receiving nebulized ketamine? Researchers will compare nebulized ketamine to a placebo (a saltwater mist with no medication) to see how well it works and how safe it is. Participants will: * Receive either nebulized ketamine or a placebo mist, along with standard asthma treatment * Have their breathing checked before and after treatment using a peak flow meter * Be monitored for 60 minutes and have their symptoms, vital signs, and any side effects recorded

Remote Patient Monitoring Solution for Chronic Respiratory Disease Management

Aim: To evaluate the use of AeviceMD Monitoring System (AeviceMD) asthma in reducing acute exacerbation. Methodology: Using a randomized controlled trial design, this project aims evaluate the effectiveness of AeviceMD in improving patients' outcomes in terms of reducing exacerbation, healthcare utilization, improving quality of life, self-efficacy, and cost effectiveness. Paediatric patients above age 7 and adults will be recruited. The data follow-up period is 3 months. It will also evaluate the usability of the device from both patients' and clinicians' perspective. 180 patients (124 adults, 56 pediatrics) and 120 clinicians will be recruited. Importance of study: This study will evaluate if the AeviceMD can help improve disease management and reduce recurrence of asthma exacerbation. Potential benefits and risk: AeviceMD allows for remote monitoring and tracking of patients' lung sounds, which could be used by patients to monitor their lung condition and prevent an episode of exacerbation or worsening exacerbations culminating in an admission which who further utilize already limited healthcare resources. An exacerbation is an episode of severe shortness of breath, cough, and chest tightening which warrants a visit to a healthcare institution. Through self-monitoring, patients can be empowered to self-manage their asthma, with aid of the asthma action plan which is given to all patients with asthma. AeviceMD can also help provide clinicians with patients' objective lung data. In the primary care setting, care is also fragmented as patients are often followed-up by a different doctor or healthcare providers. Clinicians have no objective data to track patients, and is dependent on patients' self-report and possible recall bias. There is no expected risk with the use of the device.

Timely Administration of IV Magnesium Sulfate in Patients With a Moderate Asthma Exacerbation

This study aims to identify whether early administration of magnesium sulfate in moderate asthma exacerbations can potentially avoid admission, decrease length of stay in the emergency department (ED), decrease length of stay (LOS) in the general hospital floor vs pediatric intensive care unit (PICU), and decrease the need for respiratory support.

Using the Blood Eosinophil Count to Guide Systemic Corticosteroid Treatment in Asthma Exacerbations

Asthma attacks which are moderate-to-severe are typically treated with corticosteroids, but the optimal treatment duration is unknown and treatment responses can be variable. Inadequate treatment may compromise recovery, but increased exposure to corticosteroids is, in turn, associated with drug-related adverse effects. There is a need for a biomarker to guide duration of corticosteroid treatment in asthma attacks. One such candidate biomarker is the blood eosinophil count, which may predict steroid-responsiveness. We hypothesize that the blood eosinophil count can potentially be used as a biomarker to guide the duration of corticosteroids in moderate-to-severe asthma attacks. This study will recruit individuals hospitalized for asthma attack. Participants will be randomized to standard care or blood-eosinophil guided systemic corticosteroid therapy. Subjects in the standard arm will receive oral corticosteroids for a total of 5 days. Subjects in the blood-eosinophil guided arm will receive oral corticosteroids for a total of 5 days if admission eosinophil count is ≥ 0.300 x 10\^3/µL, and receive 3 days of oral corticosteroids if the admission blood eosinophil is \< 0.300 x 10\^3/µL. The rate of treatment failure will be compared between these two groups.
