Mayourian et al., “Single lead electrocardiographic detection of left ventricular systolic dysfunction in pediatric and congenital heart disease”

Researchers affiliated with Harvard Medical School, the University of Pennsylvania, and the University of Toronto developed a noise-adapted single-lead ECG model for detecting left-ventricular systolic dysfunction in pediatric and congenital-heart-disease populations. The study used an internal cohort of 70,226 patients and external cohorts comprising 42,984 patients at Children’s Hospital of Philadelphia and 284 patients at Toronto General Hospital, reporting strong performance across different congenital conditions, age groups, racial groups, and health systems.

One in five students used generative AI for emotional support in a large Ontario study

A JAMA Pediatrics cross-sectional study of 39,761 Ontario students found that 21.1 percent used generative AI for emotional support or advice. Students reporting this affective use had higher emotional-problem scores and were more likely to cross a clinical symptom threshold than students who did not. The unadjusted prevalence was 57.7 percent versus 29.2 percent, and an association remained after adjustment for loneliness, mattering, demographic factors, and school-related AI use. The result is important and easy to overstate. A cross-sectional design cannot show that AI caused distress. Children already experiencing emotional problems may be more likely to seek a private, always-available chatbot, and both directions may operate together. The authors frame affective AI use as a distinct marker of psychological distress rather than a diagnosis or causal mechanism. That distinction should guide action. Clinicians and families should ask about chatbot use without shaming children, schools should distinguish functional assistance from emotional refuge, and products should provide age-appropriate privacy protections, clear limits, and visible escalation to qualified human support. The signal is not that every emotional conversation with AI is harmful. It is that a child turning to an algorithm may be telling adults something they have not heard elsewhere.

A $5 billion federal push links AI to health, infrastructure and science

The U.S. government has committed more than $5 billion to expand the Genesis Mission, a multi-agency effort that combines federal datasets, Department of Energy supercomputers, research facilities, and AI tools. More than 15 agencies and 278 selected projects will target problems including chronic disease, pediatric cancer, drug discovery, resilient building materials, transportation maintenance, energy, manufacturing, agriculture, and national security.
