People with atrial fibrillation have signs of the condition in their retinas that can be detected as early as four years before diagnosis, according to a new study led by University College London (UCL) and Moorfields researchers.
A research team led by UCF College of Medicine assistant professor Hung Nguyen is examining an understudied molecule within T cells as a pathway to treatments for cancers, infections and autoimmune disorders.
An elevated PSA level in the blood may indicate prostate cancer but does not allow for a definitive diagnosis. Where there is a corresponding suspicion, a tissue sample is usually taken from the prostate. A study by the Medical University of Vienna now shows that a specialized form of imaging—known as PSMA-PET/CT—could provide important additional information even before such a biopsy is carried out.
Atrial fibrillation is the most common cardiac arrhythmia and increases the risk of conditions such as stroke and heart failure. An established treatment is catheter ablation, in which physicians use thin catheters to create small scars in heart tissue to block the electrical signals that cause the arrhythmia. Despite treatment, many patients with the more difficult-to-treat form, persistent atrial fibrillation, experience recurrence.
When it comes to priorities in life, oxygen tops the list. Humans can go weeks without food and days without water. Take away the ability to breathe, however, and the clock starts ticking within minutes as the brain begins shutting down. But the life-giving gas does even more heavy lifting than you might think.
An experimental drug has been shown to improve symptoms, exercise capacity and heart failure status in patients with an inherited heart disease, according to a pair of newly published studies.
