Bioengineering Ph.D. student Holly Berns won a grant from the Brain Aneurysm Foundation to study how AI and other new technologies can change how aneurysms are discovered and treated. Her project will use AI and machine learning to examine how arteries leading to the brain are tilted and whether that tilt contributes to the formation and rupture of brain aneurysms.

The Association for Diagnostics & Laboratory Medicine (ADLM, formerly AACC) has issued expert guidance on lipid tests, which measure blood levels of fats and cholesterol to help assess a patient’s risk of heart disease and stroke. By giving clinicians and laboratory medicine professionals much-needed clarity on how to best use these tests, the new guidelines will ensure that more patients with cardiovascular disease get the treatment they need.

When a person has chronic diabetes complications - such as heart attack, stroke and nerve damage - they are more likely to have a mental health disorder, and vice versa, according to a study. Researchers say the findings highlight a need for clinicians to actively screen for mental health disorders in patients with diabetes in addition to screening for chronic complications, which is the recommended standard of care in diabetes.

People 60 and older with untreated high blood pressure may have an increased risk of Alzheimer’s disease compared to both people who have been or are being treated for high blood pressure as well as people without the chronic condition. The new research, a meta-analysis, is published in the August 14, 2024, online issue of Neurology®, the medical journal of the American Academy of Neurology. These results do not prove that untreated high blood pressure causes Alzheimer’s disease, they only show an association.
