Acute bronchiolitis

This study looks at whether monitoring the immune response to the cytomegalovirus (CMV) can help prevent CMV disease in people who receive a lung transplant. About 100 adult lung transplant patients who have had CMV in the past will be followed. The goal is to see if tracking CMV…

This study is testing a special MRI scan that uses xenon gas to take detailed pictures of lung function. It includes 260 healthy volunteers and people with lung diseases like asthma, COPD, and cystic fibrosis. The goal is to see if this method can better detect and measure lung p…

This study tests whether a computer alert can help doctors remember to prescribe blood-thinning medicine for high-risk patients after they leave the hospital. Blood clots are a serious risk for some hospitalized patients, even after discharge. The trial will include 400 adults ag…

This study explores whether young children (ages 3 months to 2 years) with moderate bronchiolitis can be cared for at home through a structured home hospitalization program. Researchers will track how many children need oxygen therapy during home care and how well families manage…

This study tests whether a nose spray made from treated seawater can shorten the time babies (1 month to 1 year) have symptoms of bronchiolitis, compared to a standard saltwater spray. About 458 infants with their first, mild-to-moderate bout of bronchiolitis will take part. Pare…

This study looks at two ways to end high flow nasal cannula treatment in infants with acute bronchiolitis. One group stops the high flow immediately, while the other gradually reduces it. The goal is to see if immediate stopping shortens hospital stays without causing more breath…

This study is analyzing the exhaled breath of 5,000 people with lung or airway diseases to find unique molecular patterns. The goal is to better identify and distinguish different respiratory conditions and improve disease management. Participants simply provide breath samples, a…

This study aims to see if analyzing the chemicals in a child's breath can help diagnose and monitor diseases like asthma, neurological disorders, and type 1 diabetes. Researchers will collect breath samples from up to 3,600 children and teens to find patterns linked to these cond…

This study creates a registry and biorepository of lung images and biological samples from 100 people with pulmonary disease. Researchers will use this information to better understand imaging biomarkers and develop new analysis methods for CT and MRI scans. Participants must alr…

This study will follow 1000 adults for up to 10 years, using a special type of CT scan (photon-counting) to look for lung nodules, tumors, and other lung conditions. Researchers will also use artificial intelligence to create a virtual copy of each person's lungs, called a 'digit…

This study measures how hard children with conditions like neuromuscular disease, scoliosis, or heart problems work to breathe. Researchers use a thin tube placed through the nose into the esophagus to measure breathing muscle strength and effort. The goal is to better understand…

This study uses donated human lungs to develop a standard method for a new freezing catheter that can take tissue samples (biopsy) and destroy abnormal tissue (ablation). Researchers will test different freezing times and temperatures to find the safest and most effective techniq…

This study follows 200 infants hospitalized with lower respiratory tract infections (like bronchiolitis) to see if lung ultrasound and special breathing tests can help doctors predict how sick a child will get and who might develop asthma later. Researchers will track symptoms, h…

This study looks at two different approaches to help doctors and families avoid unnecessary follow-up visits after a child is hospitalized for bronchiolitis. About 2,700 children will take part to see which method works better at encouraging follow-up only when needed. The goal i…

This study is building a bio-bank of blood samples from people who have had a lung transplant. Researchers will use these samples to study advanced lung diseases and improve transplant care. The goal is to better understand how infections and other factors affect patient outcomes…

This study tests whether a two-part approach—improving communication about viral infections and having pharmacists double-check prescription lengths—can reduce how many days antibiotics are prescribed for respiratory infections like bronchitis, sinusitis, and sore throat. About 4…

This study is looking for better ways to predict if a lung transplant will be rejected. Researchers will collect blood samples from 244 lung transplant recipients over time and analyze them using advanced techniques. The goal is to create a model that can identify early signs of …

This pilot study is testing a new ultrasound tool that measures how much the lungs stretch (strain) in patients on breathing machines in the ICU. The goal is to collect initial data from 10 adults with lung disease to see if this technique can help doctors better monitor and prev…
