A new MUSC study published in JAMA Pediatrics reveals a striking reversal in youth vaping trends: Girls are now vaping at higher rates than boys. Among teens ages 15 to 17, regular vaping among girls rose from 4.9% in 2021 to 7.8% in 2024, compared with 4.6% of boys. Although cigarette smoking among adolescents has fallen to historic lows, researchers warn that nicotine addiction remains a serious concern. “We have to sound the alarm bells for girls,” said Benjamin Toll, Ph.D., of MUSC Hollings Cancer Center. “But we also need to make sure that we’re addressing the boys, too.” The findings highlight the need for targeted prevention and treatment efforts to address changing patterns of youth nicotine use.

Researchers from the University of Osaka uncovered the first steps of disease development in ANCA-associated autoimmune glomerulonephritis. Injured kidney cells send signals to attract immune cells, including neutrophils, and induce inflammation. The researchers tested the effects of modified antibodies on halting disease progression in a mouse model, showing that the modified antibodies successfully reduced kidney injury. The findings offer hope for a potential treatment aimed at stopping the disease at its earliest stage.
