A mobile phone app designed to deliver suicide-specific therapy reduced suicidal behavior among high-risk psychiatric inpatients, according to a new study by scientists at Yale School of Medicine and The Ohio State University Wexner Medical Center and College of Medicine.

Parents’ workplace exposure to chemicals may be linked to a range of behavioral challenges and developmental delays in their children with autism.

Heavy use of antibiotics has led to bacterial strains that resist them, making some infections difficult to treat. Copper antimicrobials are increasingly used to reduce the emergence of resistant strains. New research shows that heavy use of copper leads to the evolution of copper-resistant E. coli bacteria that can also resist antibiotic drugs. Fortunately, when the use of copper is stopped, bacteria quickly revert to a less-resistant state, suggesting that alternating copper with other antimicrobials could be as effective without driving resistance.​​​

Modupe O. Coker of the School of Dental Medicine at the University of Pennsylvania and a collaborative team of researchers identified changes over time in the oral microbiome of children living with HIV, offering insights into how early immune challenges shape not only oral but also systemic health. “Mouth microbes are central to health,” says Coker. “But bacteria in the mouth don’t stay in the mouth—they extend to the rest of the body, influencing system health and vice versa.”

About The Study: In this cohort study of adults prescribed semaglutide, initiation was associated with reductions in weight and cardiovascular risk factors but increases in health care expenditures, excluding semaglutide costs. These findings suggest potential clinical benefits in routine practice, while highlighting the need to evaluate the long-term impact of semaglutide on economic outcomes.

About The Study: In this cross-sectional study of 143 health conditions among persons in 50 states and Washington, DC, per capita pharmaceutical use was highest among white populations and lowest among Asian or Pacific Islander and Hispanic populations. However, after standardizing for age and disease prevalence (for 52 conditions with available data), prescription fills were substantially lower for Black populations relative to the all-population mean. These patterns varied by state, highlighting the need for local- and condition-specific approaches to advancing pharmacoequity in the U.S.
