3D jaw study for sleep breathing problems
This study looks at how a small lower jaw and large overbite relate to sleep-related breathing issues, using 3D scans and functional appliances.
Rijeka, Primorje-Gorski Kotar CountyAges 10–14 - NCT06436209Recruiting
Brain study on thinking and attention
This study uses brain scans to see how the front part of the brain controls attention and thinking. If you are right-handed and healthy, you may help researchers learn more about how the brain works.
Providence, Rhode IslandAges 18–35 - NCT06360900Recruiting
Vagus nerve stimulation study for functional dyspepsia
This trial tests a combination of a non-invasive nerve stimulation device and supportive therapy to help people with functional dyspepsia. The goal is to improve digestion and reduce stomach pain.
Boston, MassachusettsAges 18–65 - NCT06029374Recruiting
Comparing treatments for hand bone fractures
This trial compares two treatments for a common hand fracture—the boxer's fracture—to see if one is better. It will help people recover quickly without surgery.
ViennaAges 18–70 - NCT05641597Recruiting
Free fibula bone transfer study after reconstructive surgery
This study looks at how well a specific reconstructive operation works for a person’s daily function, especially after surgery that replaces part of bone using a healthy bone and blood supply. It may help the team understand what recovery and movement outcomes to expect after this procedure.
DijonAges 18 years+ - NCT05666154Recruiting
Testing a specific diet using a special camera for stomach symptoms
This study tests whether a tailored diet can improve symptoms in people with functional dyspepsia (stomach discomfort without a clear physical cause). It also uses a special in-hospital camera exam to look at the stomach lining and understand how the diet affects you.
LeuvenAges 18–70 - NCT05280028Recruiting
Hormone treatment for overactive bladder and mood symptoms
This trial studies whether hormone treatment can improve overactive bladder symptoms, sexual well-being, mood (depressive symptoms), and body “autonomic” function (automatic body functions like heart rate and sweating) in post-menopausal women. It may help by targeting menopausal changes that can affect these symptoms.
Banqiao District, New TaipeiAges 20 years+ - NCT05612906Recruiting
Nerve ablation study for difficult high blood pressure
This trial studies a procedure called renal nerve denervation (ablation) to improve kidney-related blood pressure in people whose blood pressure stays high despite medications. It may help some people lower blood pressure and improve blood pressure control over time.
Xiamen, FujianAges 18–75 - NCT05473793Recruiting
