This study uses the Swedish Heart Failure Registry to identify patients with heart failure and reduced ejection fraction who are not on optimal treatment. Researchers will then help start or adjust medications, screen for iron deficiency, and refer for devices or physiotherapy. T…

This study is testing whether giving high-flow nasal oxygen right after major surgery can reduce lung complications in frail adults. About 200 high-risk patients having abdominal or chest surgery will be randomly assigned to receive either high-flow oxygen or standard oxygen. The…

This study looks at people with ulcerative colitis whose disease is still active after trying at least two advanced medications. Participants choose either to continue trying different drugs or to have surgery to remove the colon. The study will compare quality of life, daily fun…

This study tests whether dapagliflozin, a drug used for diabetes, can reduce the return of atrial fibrillation (an irregular heartbeat) after a procedure called electrical cardioversion that shocks the heart back to normal rhythm. About 1600 adults aged 55 and older with atrial f…

This study tests a new MRI sequence that aims to make brain tumors (metastases) more visible after contrast injection. Researchers will compare the new method to standard MRI in 100 adults with known or suspected brain tumors. The goal is to see if the new scan finds more or smal…

This study tests whether a new CT-angiography method can accurately diagnose brain death compared to the standard four-vessel angiography. About 50 adults with severe brain injury will receive both tests. If the CT method works as well, it could offer a faster, less invasive way …

This study tests if a 12-week cognitive behavioral therapy (CBT) program can help people with paraphilic disorders reduce problematic sexual behaviors and improve their mental health. Researchers will track daily symptoms and interview participants about their experiences. The go…

This study tests whether brief cognitive behavioral therapy (CBT) can help people hospitalized for depression or anxiety. About 204 patients will receive CBT sessions during their stay. The goal is to see if this therapy reduces symptoms and improves daily functioning.

This study tests whether heart failure patients can safely drink as much fluid as they want instead of restricting it. Researchers will compare lung congestion, blood markers, quality of life, and hospital readmissions in 326 participants over time. The goal is to see if liberal …

This study aims to find out how many people who inject drugs experience intimate partner violence (IPV) and what kinds of violence they face. Researchers will survey 500 adults at needle syringe programs in Sweden. The goal is to learn about their experiences and what support the…

This study tests whether a special MRI scan can track lung tumor movement during breathing better than the standard CT scan. Researchers will compare both scans in 150 people receiving radiation therapy for lung cancer. If the MRI proves more accurate, it could help doctors plan …

This study observes 200 adults who had a bleeding aneurysm and are at risk for delayed brain damage from narrowed blood vessels. Researchers use special ultrasound and brain monitoring to track blood flow changes. The goal is to better understand when and why delayed strokes happ…

This study compares 240 adults with paraphilic disorders, compulsive sexual behavior, or sexsomnia to healthy controls. Researchers aim to understand differences in violence history, psychiatric traits, and genetic factors. Participants will be followed for up to 10 years to see …

This study looks at why sarcoidosis affects people differently—some get better, others develop long-term lung damage. Researchers will analyze genes, immune cells, and gut bacteria from 5,000 participants, including healthy volunteers. The goal is to find markers that predict dis…

This study looks at whether doctors can rely on feeling a patient's pulse to estimate blood pressure during shock. Researchers will compare pulse checks with actual blood pressure readings in 5000 adults in emergency and intensive care. The goal is to improve rapid assessment and…

This study tests a new way to make brain MRI scans clearer by fixing distortions caused by breathing. About 100 adults having routine brain scans will have their images processed with and without the new correction method. The goal is to see if the corrected images are sharper an…

This study is testing whether a new genetic test (called PCAI ImmunoScore) can predict how well men with high-risk prostate cancer will respond to the drug darolutamide before surgery. About 100 participants will take darolutamide for 3-4 months, then have their prostate removed.…
