and Barrow Neurological Foundation contributed to a landmark study that is helping to unravel the mysteries behind why some aneurysms rupture while others do not. These findings could help us better predict and prevent hemorrhagic .

An estimated 1 in 50 Americans has a , which is a balloon-like bulge on a weakened blood vessel wall in the brain. While some brain aneurysms may never cause problems, others can burst and lead to life-threatening brain bleeds. Predicting which aneurysms require intervention and which can be monitored has always been challenging, due to unknowns about the underlying biology of these malformations.

The new study, led by UCSF and published June 10 in “Nature ,” analyzed more than 100,000 individual cells from human aneurysms and healthy brain arteries. The researchers identified a process in which scar-forming cells replace supportive muscle cells in the blood vessels, activating inflammatory immune cells and gradually weakening the vessel walls.

The paper's senior author, UCSF Associate Professor Ethan Winkler, MD, PhD, is a graduate of the and /skull base fellowships at Barrow. He was mentored by Barrow President and CEO Michael T. Lawton, MD, a corresponding author on the paper. Barrow faculty Ruchira Jha, MD, MSc; S. Paul Oh, PhD; and Tomoki Hashimoto, MD, are also authors on the paper, along with Barrow alumni Lea Scherschinksi, MD, and Joshua Catapano, MD.

: In April, members of the Barrow Global team attended the Second Annual World Federation of Neurosurgical Societies (WFNS) International Conference in Dar es Salaam, Tanzania. This year's meeting was held in collaboration with the inaugural International Society of Global Neurosurgery (ISGNS) Conference and marked one year since the Boston Declaration—a formal pledge to strengthen research, expand access, and advance education in neurosurgery.

Tanzanian President Samia Suluhu Hassan (pictured in the middle of the seated row) addressed conference attendees, affirming the country's commitment to bolstering neurosurgery access and services. Dr. Kerry Vaughan, the Africa site director for (also pictured), presented a video message from the World Health Organization (WHO)'s regional director for Africa, Dr. Mohamed Janabi, and Barrow Global Co-Director Dr. Dilan Ellegala. Dr. Vaughan also gave talks on workforce migration factors and leadership strategies.

Barrow neurosurgery resident Dr. Cyrus Elahi and Barrow spine research fellow Dr. Francisco Rivera provided one-year updates on 's commitments made at the Boston Declaration, alongside Kilimanjaro Christian Medical Centre (KCMC) neurosurgery resident Dr. Dyllan Omwenga.

Dr. Gail Rosseau, adjunct faculty and co-organizer of the conference, acknowledged her volunteer assistant and incoming Barrow neurosurgery resident Dr. Nikki Perez for her contributions.
