USC researchers define brain scan marker to better classify Alzheimer’s disease-related changes

A new brain imaging benchmark may improve how researchers classify biologically meaningful changes associated with Alzheimer’s disease. Researchers found a tau cut-point that distinguished individuals with cognitive impairment from those aging normally, but its effectiveness was limited in non-Hispanic Black participants.

New USC study links wildfire smoke exposure and heat stress to adverse birth outcomes

A recent USC study found associations between increased exposure to wildfire smoke and heat stress during preconception and the first trimester with the odds of having a small-for-gestational-age infant. Living in a climate-vulnerable neighborhood can increase these risks, particularly for women exposed to heat stress.

USC study reveals link between type 2 diabetes and brain health in older adults from various populations

A new USC-led study found a significant link between type 2 diabetes and cortical thickness in older adults from various populations. The researchers discovered that individuals with T2DM exhibited thinner cortex, particularly in temporal and parietal regions critical for memory and cognitive function.

USC researchers develop low-cost blood test for early Alzheimer’s detection

Researchers from USC Keck School of Medicine have developed a low-cost blood test that detects five biomarkers of Alzheimer's disease, including amyloid and tau proteins. The test uses xMAP technology and has the potential to catch the disease in its earliest stages, when treatment might be able to prevent or delay cognitive decline.

New research analysis predicts that reductions in Medicaid access could result in poorer health outcomes, including increased deaths

A new analysis predicts that reducing Medicaid access could lead to thousands of additional deaths among working-age Americans and disastrous financial burdens. The study found that eliminating the ACA provision expanding Medicaid access could drive millions to delay needed care.

Most COVID-19 treatments found to be free of serious side effects in analysis of U.S. studies

The study analyzed 54 U.S. studies and found no significant association with serious adverse events for oral antivirals like Paxlovid or monoclonal antibodies. Actemra was associated with infection and low white blood cell counts, while transfusions of convalescent plasma were linked to internal bleeding and blood clots.

USC Stem Cell mouse study identifies shared genes involved in hearing and vision regeneration

A USC Stem Cell mouse study has identified shared genes involved in regenerating cells in the ear and eye, which could lead to new treatments for hearing and vision loss. The researchers discovered that inhibiting a specific protein, p27Kip1, can encourage regeneration in both organs.

Calorie-free sweeteners can disrupt the brain’s appetite signals

A study found that consuming sucralose alters brain activity related to hunger and increases appetite, especially in people with obesity. The sugar substitute changes how the hypothalamus communicates with other brain regions, including those involved in motivation, potentially leading to cravings and eating behavior changes.

Blood pressure patterns during pregnancy predict later hypertension risk, study finds

A longitudinal study of Hispanic mothers found that women with normal blood pressure levels during pregnancy but no mid-pregnancy drop in blood pressure face an increased risk of developing hypertension after giving birth. Tracking blood pressure patterns during pregnancy may help identify these women and prevent cardiovascular disease.

USC study shows persistent organic pollutants are associated with higher blood pressure in teenagers after weight loss surgery

Researchers found that exposure to persistent organic pollutants (POPs) stored in body fat leads to disruptions in lipid metabolism and altered prostaglandin pathways, contributing to long-term higher blood pressure in adolescents. POPs diminish the beneficial effect of bariatric surgery on improved blood pressure.

USC study shows proteins and pathways involved in inflammation are associated with changes in bone mineral density over time

A USC study found proteins and pathways involved in inflammation are associated with changes in bone mineral density (BMD) over time. The research identified potential biomarkers that could serve as early indicators of a person's risk for bone health issues later in life.

Prenatal maternal stressors linked to higher blood pressure during first year after birth, study shows

Research from Keck School of Medicine of USC found that mothers with high prenatal psychosocial stress and depressive symptoms developed higher blood pressure during the first year postpartum. Social cohesion during pregnancy was also associated with lower blood pressure, suggesting a protective factor.

USC study finds new evidence linking dementia to problems with the brain’s waste clearance system

A new USC study validates a biomarker linked to vascular dementia and suggests that glymphatic damage drives cognitive decline. The findings provide a potential pathway to explain how cognitive impairment arises, offering a target for clinical researchers seeking treatments for vascular dementia.

USC Stem Cell study breaks the silence on how fish and lizards regenerate hearing

A USC Stem Cell study has identified key gene regulators that enable some deafened animals, including fish and lizards, to naturally regenerate their hearing. The researchers found a class of DNA control elements known as 'enhancers' that amplify the production of a protein called ATOH1, which induces sensory cells in the inner ear.

Study finds health disparities in PFAS levels linked to drinking water, food access and industrial pollution

Researchers found that living in neighborhoods with low food access, contaminated drinking water, and proximity to Superfund sites increases PFAS levels in blood. The study provides evidence for addressing neighborhood-level factors in reducing racial and ethnic environmental health disparities.
