On May 26, 2020, University of Nebraska Medical Center (UNMC) researchers were part of a large national study that will change how physicians treat small abdominal aortic aneurysms. The researchers found doxycycline, a commonly used antibiotic, had no beneficial effect compared to a placebo in slowing growth of the aneurysms.

The major finding, published in the Journal of the American Medical Association, was funded by a $10 million grant by the National Institutes of Health National Institute on Aging.
