Indigenous people in the United States are at higher risk of fatal police violence in and around American Indian/Alaska Native (AIAN) reservations, according to the first comprehensive national study on the subject from researchers at Drexel University’s Dornsife School of Public Health and the University of Washington. The study, using data on the 203 AIAN people killed by police from 2013 through 2024, was published today in the journal PNAS. The authors hope this work will inform policy action to better protect these communities.

Telemedicine remains popular following its surge during the COVID-19 pandemic, but some disparities in use exist

The Global Virus Network (GVN) marked the opening of its International Headquarters on March 5 at the University of South Florida (USF) Institute for Translational Virology and Innovation (ITVI), a GVN Center of Excellence. The Global Virus Network represents eminent human and animal virologists from more than 90 Centers of Excellence and Affiliates across over 40 countries working to advance research, collaboration and pandemic preparedness.

Increasing our level of physical fitness leads to a bigger release of brain-boosting proteins following one session of exercise, a new study led by a UCL researcher has found.

New model can better equip public health officials to address outbreak risks unique to their region.

An analysis led by Mass General Brigham investigators found slower aging in older adults after two years of a daily multivitamin, with greater benefits for those who began the trial with accelerated biological age

Women with certain cardiometabolic risk factors, including type 2 diabetes and high waist circumference, face a greater increase in risk for liver fibrosis than men with the same risk factors. The study, just published in JAMA Network Open, is one of the first to explore sex differences in cardiometabolic risk factors for liver fibrosis, a condition on the rise globally. Data came from the U.S. Centers for Disease Control and Prevention’s National Health and Nutrition Examination Survey. The researchers included data from 5,981 U.S. adults, representative of the U.S. population with an average age of 47, collected between 2017 and 2020. They analyzed whether the link between liver fibrosis and key cardiometabolic risk factors differed by sex, including waist circumference, high blood pressure, diabetes or pre-diabetes, high triglycerides, low high-density lipoprotein (HDL) cholesterol and the presence of two or more of these factors. In their statistical analysis, the researchers controlled for age, race, ethnicity, smoking and alcohol intake to rule out the influence of those factors. Overall, women faced similar or lower baseline rates of liver fibrosis compared with men. However, when certain risk factors were present, women’s fibrosis rates tended to increase more sharply than men. For example, high waist circumference was associated with an increase in fibrosis rates from 0.8% to 9.2% in women (about 11-fold), compared with an increase from 4.4% to 17.0% in men (about fourfold). Type 2 diabetes or pre-diabetes was linked to a 2.8-fold increase in fibrosis rates among women, versus a 1.4-fold increase among men. Having two or more cardiometabolic risk factors was associated with an 8.4-fold increase in women, compared to a 2.6-fold increase in men. The findings underscore that maintaining good heart and metabolic health has implications well beyond heart disease prevention.
