This study tests whether taking a daily probiotic supplement for six months can improve immune function in people with relapsing-remitting multiple sclerosis (MS). Eighty adults aged 18-55 will be randomly assigned to receive either the probiotic or a placebo, alongside their usu…

This early-phase trial tests whether a powerful immune reset using a patient's own stem cells can clear the antibodies that block them from receiving a kidney transplant. Ten highly sensitized adults with end-stage kidney disease will undergo intense conditioning to wipe out thei…

This study tests whether a home hospitalization program (NORA-HOME) is safe and effective for people who have had a minor stroke or transient ischemic attack (TIA). Researchers will compare home monitoring with standard hospital care in 250 participants. The goal is to see if hom…

This observational study will follow 700 people with migraine who are prescribed anti-CGRP drugs (monoclonal antibodies or gepants) for prevention. Over two years, researchers will track changes in monthly headache days, migraine impact, and disability. The goal is to see how the…

This study tests a simple, at-home video program that teaches people how to better control their anal and belly muscles to reduce accidental bowel leaks and improve constipation. About 96 adults with these issues will either use the video exercises or take a placebo pill. The goa…

This study tests whether adding virtual reality (VR) mindfulness sessions to standard treatment can help people with treatment-resistant depression feel better. Thirty adults who haven't responded to multiple antidepressants will either get usual care alone or usual care plus 8 V…

This study tests whether a simple biofeedback technique—teaching people to control their abdominal and chest muscles using a video—can reduce visible bloating after meals. 100 adults with irritable bowel syndrome, dyspepsia, or functional bloating will be randomly assigned to eit…

This study looks at whether people with heart rhythm problems after a TAVI procedure can safely leave the hospital early if they wear a non-invasive heart monitor at home. About 100 adults who had a successful TAVI for severe aortic stenosis and have certain conduction disorders …

This study aims to create a better way to predict stroke risk in people with atrial fibrillation (an irregular heartbeat) who are already taking direct oral anticoagulants (DOACs), a type of blood thinner. Even with these medications, some patients still have strokes. Researchers…

This study explores whether a moderate physical activity program (3 times a week, 60 minutes each) is practical and acceptable for pregnant women who face social or economic difficulties. Researchers will track how many women join, why some say no, and what helps or hinders exerc…

This study follows 600 patients aged 80 and older who are having planned surgery requiring a hospital stay. Instead of only looking at medical outcomes like complications, researchers will ask patients to fill out a questionnaire (QoR-15E) about their physical, emotional, and psy…

This study follows 100 people in Spain with nemaline myopathy, a rare muscle disease, to see how their symptoms change over time. Researchers will use ultrasound, movement tests, and breathing checks to map the disease's natural course. The goal is to build a detailed patient dat…

This study is testing a Spanish version of a questionnaire that helps identify emotional distress and unmet needs in adolescents and young adults (ages 15-25) with cancer. Researchers will enroll 100 participants to see if the tool accurately measures psychosocial challenges. If …

This study is testing whether a non-invasive ultrasound scan, combined with artificial intelligence (AI), can quickly identify bleeding in the brain (intracerebral hemorrhage) in people having a stroke. Researchers will enroll 500 adults with acute stroke and perform a standard C…

This study is testing whether a blood test that measures certain markers (sFlt-1/PlGF) can help doctors decide when to deliver babies in women with mild preeclampsia at term. Instead of automatically inducing labor at 37 weeks, women with normal test results would wait until 39 w…

This study is for people with sickle cell disease or other rare anemias. Researchers want to use advanced genetic and blood tests to better understand each person's condition. The goal is to make diagnosis more precise so that treatments can be tailored to each patient. About 200…
