(Press-News.org) Nearly one in five U.S. veterans have experienced a traumatic brain injury (TBI), mostly in the form of a concussion. Now, the full long-term health consequences of TBI are starting to be uncovered, thanks in large part to the work of Mary Jo Pugh, PhD, RN, professor of epidemiology at University of Utah Health and investigator with the Informatics, Decision-Enhancement and Analytical Sciences (IDEAS) Center of Innovation at the VA Salt Lake City Healthcare System.
On August 4, Pugh won an Outstanding Research Accomplishment award at the 2025 Military Health System Research Symposium for her TBI research. The award recognizes individual investigators who have recently made outstanding contributions to medical research via work funded by the Department of Defense. Pugh is one of only two investigators nationwide to receive this honor.
Pugh’s work revealed that TBI is associated with many long-term health consequences that were previously unknown, including dementia, substance use disorder, and even cardiovascular disease. TBI is also linked to higher risk of suicide and cancer. Uncovering these patterns of risk is a first step toward preemptive interventions to help veterans with TBI stay healthy.
Key to her work is Pugh’s ability to uncover patterns hidden within big data. Her work helped integrate health data between the VA and the Department of Defense—an essential step to understanding how TBI acquired during military service can impact health after someone leaves the military.
“This linkage is invaluable because it allows us to analyze long-term health outcomes while incorporating crucial details from military service—such as injury characteristics and blast exposures—that are missing from VA data alone,” Pugh says.
“This ‘gold mine’ of data has enabled rapid and critical surveillance of Military Occupational Blast Exposure (MOBE) from large weapons,” she adds, “which is vital because many service members with MOBE do not have a specific documented injury or diagnosis, which is essential to demonstrate service connection for disability claims.”
Pugh leads the Data and Biostatistics Core for a national research consortium called LIMBIC, a DoD- and VA-funded group that brings together nearly 40 organizations to study the chronic effects of brain trauma in a cohort of over 2.5 million people.
To spot new patterns within this data, Pugh uses a strategy called complexity theory. This method of data analysis allows her to disentangle the effects of concussion from other contributors to health, finding long-term health outcomes that other analyses don’t detect.
Matthew Samore, MD, principal investigator of the IDEAS Center and the VA Consortium for Healthcare Informatics Research, says that Pugh’s research has had fundamental impacts. “Dr. Pugh’s contributions of foundational knowledge about the detrimental effects of blast exposure have been instrumental in shaping policy and response,” says Samore, who also serves as division chief of epidemiology at U of U Health.
“I am incredibly proud of our work,” Pugh adds. “This award validates the exceptional work of my team over the past 20 years.”

U. Iowa research identifies promising new target for treating rare, aggressive childhood cancer
2025-08-18
A new study delving into the genetic drivers of a rare and aggressive childhood cancer called Malignant Peripheral Nerve Sheath Tumor (MPNST) has revealed metabolic frailties in the cancer cells that might be exploited to improved treatments for patients.
MPNST is a rare and deadly childhood cancer, which mainly affects teenagers and young adults. These tumors grow quickly, spread easily, and don’t respond well to current treatments. Metastasis is the leading cause of death in MPNST and there currently are no targeted ...
North Pacific waters are acidifying more rapidly below the surface
2025-08-18
Carbon dioxide in the atmosphere enters the ocean at the surface and has been increasing the acidity of Pacific waters since the beginning of the industrial revolution over 200 years ago. A new study, led by University of Hawai‘i at Mānoa oceanographers, revealed that the ocean is acidifying even more rapidly below the surface in the open waters of the North Pacific near Hawai‘i. Their discovery was published recently in the Journal of Geophysical Research: Oceans.
“Ocean ...
Researchers find intensive blood pressure targets are cost-effective
2025-08-18
Research led by investigators at Mass General Brigham suggests that the health benefits of more aggressive blood pressure control outweigh concerns about overtreating people with high blood pressure readings. Results of the simulation study are published in Annals of Internal Medicine.
The study used data from the Systolic Blood Pressure Intervention Trial (SPRINT) trial, the National Health and Nutrition Examination Survey (NHANES), and other published literature to simulate lifetime health outcomes—including heart attack, stroke, and heart failure—for patients whose systolic blood pressure targets were set at <120 mm Hg, <130 mm Hg, and <140 mm Hg. Recognizing ...
A shape-changing antenna for more versatile sensing and communication
2025-08-18
CAMBRIDGE, MA – MIT researchers have developed a reconfigurable antenna that dynamically adjusts its frequency range by changing its physical shape, making it more versatile for communications and sensing than static antennas.
A user can stretch, bend, or compress the antenna to make reversible changes to its radiation properties, enabling a device to operate in a wider frequency range without the need for complex, moving parts. With an adjustable frequency range, a reconfigurable antenna could adapt to changing environmental conditions and reduce the need for multiple antennas.
The word “antenna” ...
New method advances reliability of AI with applications in medical diagnostics

MEDIA EMBARGO: 3 p.m. EASTERN TIME AUGUST 18, 2025
They feel like lightning — sudden, brilliant and seemingly impossible to predict. But according to new research, those mind-flashing “aha” moments of insight may leave detectable traces before they strike.
Scientists have developed a way to identify subtle behavioral changes that happen minutes before a breakthrough, offering a new window into the elusive mechanics of human creativity.
The study was published in the Proceedings of the National Academy of Sciences. Shadab Tabatabaeian, who earned her Ph.D. in Cognitive and Information Sciences from the University of California, Merced, is lead author, ...
An alphabet for hand actions in the human brain
2025-08-18
Using a corkscrew, writing a letter with a pen or unlocking a door by turning a key are actions that seem simple but actually require a complex orchestration of precise movements. So, how does the brain do it?
According to a new study by researchers from Carnegie Mellon University and the University of Coimbra, the human brain has a specialized system that builds these actions in a surprisingly systematic way.
Analogous to how all of the words in a language can be created by recombining the letters of its alphabet, the full repertoire ...
When rattlesnakes marry their cousins
2025-08-18
Roads, buildings and farms are preventing Michigan’s only rattlesnake from finding mates outside of their population. A 15-year study shows that fragmentation into smaller, more isolated patches is likely reducing the threatened snake’s chances of survival.
Michigan State University conservation biologists traced the family histories of more than 1,000 Eastern Massasauga rattlesnakes caught and released in a U.S. Fish and Wildlife Service-funded project. The new findings, published in the Proceedings of the National Academy of Sciences, surprised even the researchers – the most inbred snakes were ...
Mass spectrometry sequencing of circulating antibodies from a malaria-exposed child provides new insight into malaria immunity
2025-08-18
Malaria, caused by Plasmodium falciparum, remains a major global health threat, claiming 600,000 lives annually, mostly young children in sub-Saharan Africa. Immunity to severe malaria develops after repeated infections and is mediated by antibodies blocking the parasite’s highly diversified PfEMP1 adhesion proteins from binding to the human endothelial protein C receptor (EPCR) on blood vessel walls.
In the collaborative study, researchers from the National Institute for Medical Research in Tanzania and the University of Copenhagen first identified donors with immune plasma able to ...
