This study is testing whether a special MRI using xenon gas can better detect bronchiolitis obliterans syndrome (BOS), a serious lung condition, in children who have had a stem-cell transplant. Fifteen children aged 6 to 17 will undergo breathing tests and the xenon MRI. The goal…

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 how well seawater nasal sprays work in everyday life for people with nasal and sinus issues like colds, allergies, or after surgery. About 1065 people of all ages, including pregnant women, will use the sprays and report their symptoms. The goal is to see if t…

This study compares two types of non-invasive breathing support for infants under 2 years old with bronchiolitis in the pediatric ICU. One method uses standard ventilation, while the other uses a smarter mode called NAVA that synchronizes with the baby's own breathing. The goal i…

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 aims to find out how often rhinovirus (the virus behind many common colds) causes serious breathing problems that require hospital care in children. Researchers will follow 120 young children at home for 3 years and study 450 hospitalized infants and children, plus 100…

This study is testing a new type of MRI that uses xenon gas to see how well the lungs are working in people who have had a bone marrow transplant. Researchers will scan 25 transplant patients with or without lung problems, plus 10 healthy volunteers. The goal is to see if this MR…

This study looks at children aged 1 month to 6 years who are hospitalized with a severe respiratory infection caused by adenovirus or rhinovirus. The goal is to compare the airway cells of those who develop a rare lung condition called post-infectious bronchiolitis obliterans (PI…

This study looks for early signs that a treatment called ECP is working in people who have had a lung transplant and developed chronic rejection (CLAD). Researchers will collect blood samples and, for some, lung MRI scans before, during, and after ECP therapy. The goal is to find…

This study looks at the immune system's response in infants aged 6 months or younger who are hospitalized with RSV bronchiolitis. Researchers will collect nasal swabs and blood samples to measure immune markers like interferons and cytokines. The goal is to understand why some ba…

This study follows 2,000 children who receive stem cell transplants to better understand and detect lung injuries that can occur after the procedure. Researchers will track participants for two years, collecting samples and health data to find ways to diagnose problems earlier. T…

This study looks at whether a common asthma drug, albuterol, helps babies with bronchiolitis (a lung infection). Researchers will give 400 children either albuterol or a placebo and check their breathing. They will also collect DNA samples to see if certain genes predict who gets…
