This study aims to improve treatment for people with heart failure by using a Swedish registry to find those who need medication changes, iron deficiency screening, or heart devices. About 1,000 participants will be split into two groups: one gets extra support to optimize their …

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 whether using high-flow nasal oxygen right after major abdominal or chest surgery can lower the chance of lung complications in frail adults. About 200 high-risk patients will be randomly assigned to receive either high-flow oxygen or standard oxygen therapy. The…

This study looks at people with ulcerative colitis whose disease is still active after trying at least two advanced medications. It compares quality of life between those who continue trying different drugs and those who choose surgery to remove the colon. The goal is to help fut…

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 compares a new type of MRI scan to the standard method for finding brain metastases (cancer that has spread to the brain). About 100 adults with known or suspected brain metastases will receive both scans after a contrast injection. The goal is to see if the new method…

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 aims to find out how common intimate partner violence (IPV) is among people who inject drugs in Sweden, and what their experiences and needs are. Researchers will survey 500 adults who use a needle exchange program in Stockholm. The goal is to gather information that c…

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 tests whether dynamic MRI can more accurately measure how lung tumors move when a person breathes, compared to standard CT scans. About 150 adults receiving radiation for lung tumors will have both scans, and researchers will compare the motion data. The goal is to hel…

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 whether people with heart failure can safely drink as much fluid as they want, instead of limiting it. About 326 adults with heart failure will either follow a restricted fluid plan or drink freely. The goal is to see if free drinking is safe and improves quality…

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.…
