Montreal, QuebecAges 18 years+ - NCT04157361Recruiting
Non-invasive lung testing in asthma and cystic fibrosis
This trial studies how well a non-invasive lung test can show lung involvement in people with asthma (especially IgE-related asthma) and people with cystic fibrosis. You might benefit by getting extra lung assessments without invasive procedures.
OlomoucAges Any age - NCT04164173Recruiting
Breathing therapies after heart surgery for lung overinflation
This study looks at breathing (respiratory) therapies to help after certain heart surgeries that can cause the lungs to feel overly inflated. If you’re eligible, you may receive and be assessed for how well these breathing treatments work during your recovery.
Dallas, TexasAges 18–80 - NCT04399200Recruiting
Study apnea after stroke to prevent new heart events
This trial looks at sleep apnea (breathing pauses during sleep) in people soon after a first stroke or a TIA, to see if it can be linked to new cardiovascular (heart/blood vessel) events. It also aims to make sure you can safely follow the study and rehabilitation plan.
GrenobleAges 18–85 - NCT04429100Recruiting
Breath-hold MRI test to measure liver scar levels
This study tests an MRI technique that briefly holds your breath to measure how scarred your liver tissue is. It may help doctors better spot and track liver fibrosis (scarring).
Hong Kong, ShatinAges Any age - NCT04475952Recruiting
Diagnosing upper digestive problems earlier during routine care
This study aims to learn how to detect problems in the upper digestive tract earlier. People may be asked to help with diagnosis while they are already undergoing routine tests or treatment, which could improve future care.
LondonAges 18–90 - NCT04670640Recruiting
Study of brain and therapy factors in trauma-related dissociation
This study looks at how dissociation (feeling detached or unreal) works in people who have had trauma. It tests different “mechanistic” approaches to better understand the brain and how to help, and whether participation can reduce these symptoms.
Atlanta, GeorgiaAges 18–65 - NCT04923958Recruiting
Testing new TB screening and diagnostic tests
This study tests rapid TB screening and lab-style diagnostic methods to see how well they find TB disease and TB that is resistant to rifampin (a key TB drug). It may help doctors diagnose TB faster and more accurately, especially in people at higher risk.
TbilisiAges 12 years+ - NCT04941326Recruiting
Spinal mobilization for breathing in Parkinson’s disease
This study tests whether a hands-on therapy to the spine can improve breathing measures in people with Parkinson’s disease. If you qualify, you would receive spinal mobilization and have your breathing assessed to see if it helps.
BoluAges 50–85 - NCT04974593RecruitingPhase 3
Test breath testing to guide a lactose-free diet in IBS
This trial studies whether a breath test (hydrogen/methane lactose testing) can predict who with IBS will improve on a lactose-free diet. If you have moderate-to-severe IBS and regularly eat lactose-containing foods, the test result may help tailor your diet approach.
Jette, Brussels CapitalAges 18–75 - NCT05051254Recruiting
Breathing muscle testing in children with breathing muscle weakness
This study looks at how hard it is for children to breathe and how their breathing muscles work, using specific breathing-related tests. It may help doctors better understand breathing problems and choose care more effectively.
ParisAges birth–17 years - NCT05178056Recruiting
Spinal cord stimulator to improve breathing after spinal injury
This study looks at whether a spinal cord stimulator can improve breathing and lung function in adults with a certain type of spinal cord injury. It may help people who have ongoing breathing weakness after their injury.
Louisville, KentuckyAges 18 years+ - NCT05226247Recruiting
Check whether careful weaning prevents lung fluid buildup
This study looks at people on a breathing machine for more than 48 hours who are starting a “spontaneous breathing trial,” a test used to see if they can breathe on their own. It focuses on those at higher risk of “weaning-induced pulmonary edema,” meaning fluid can collect in the lungs during the weaning process.
DijonAges 18 years+ - NCT05336890Recruiting
Using past oxygen data to predict risks after premature birth
This study builds a personalized computer model that uses earlier breathing/oxygen information from preterm infants to predict possible health or development outcomes by preschool age. It may help families and doctors better estimate risks and plan support, using information already collected in a previous study.
Chicago, IllinoisAges 7 months–6.9 years - NCT05347875Recruiting
App training to improve walking aid skills
This trial tests an app-based program meant to help people who already use walking aids learn and practice safer walking aid skills. It may help you move more comfortably if you can use the app and communicate with the study team.
Calgary, AlbertaAges 18–99 - NCT05375149Recruiting
Breath particle study after lung transplant
This study looks at tiny particles in exhaled breath after a lung transplant. It may help researchers understand how the lungs are doing after transplant by using breath samples.
Lund, Skåne CountyAges 16–75 - NCT05412758Recruiting
Breath and blood tests to study stomach and food-pipe cancer
This study looks at how certain “volatile” substances in breath change in people with stomach or food-pipe (oesophageal) cancer, compared with people who have other non-cancer stomach/food-pipe conditions. It may help researchers find better, earlier ways to assess cancer—especially in people who have not started treatment yet.
LondonAges 18–90 - NCT05427136Recruiting
Study early lung problems after childhood cancer treatment
