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.

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 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.

USC Stem Cell mouse study sheds light on the secret to maintaining a youthful immune system

A USC Stem Cell mouse study identifies a small subset of blood stem cells as the primary driver of immune aging. The researchers found that this subset overproduces innate immune cells, leading to an age-associated imbalance and increased disease risk. By targeting this subset, the study suggests a potential therapy to delay immune agi...

USC study finds link between PFAS, kidney function and gut health

Researchers at USC found a link between per- and polyfluoroalkyl substances (PFAS) and kidney damage, which may be tied to dysregulation of the gut microbiome. The study, published in Science of the Total Environment, suggests that changes in gut bacteria and related metabolites can explain up to 50% of decreased kidney function.
