AI effectively predicts dementia risk in American Indian/Alaska Native elders

Machine learning algorithms utilizing electronic health records can effectively predict two-year dementia risk among American Indian/Alaska Native adults aged 65 years and older, according to a University of California, Irvine-led study. The findings provide a valuable framework for other health care systems, particularly those serving resource-limited populations.

Smart skin sensor offers real-time infection detection

An international team led by researchers from the Universitat Rovira i Virgili (URV) has developed an innovative piece of equipment in the field of medical technology: an intelligent device capable of monitoring the temperature of the skin continuously and accurately. The device uses a thermoelectric system that works without batteries or an external power supply to detect temperature variations associated with inflammation and infection. The results of the project have been published in the journal Advanced Science.

Lung cancer screening lags behind breast and colorectal screenings

Lung cancer screening has the potential to catch lung cancer early and save lives—but only if people get screened. Although lung cancer screening is recommended in the U.S. for certain individuals with a history of smoking, only 18% of eligible individuals in the U.S. get screened. One suggested explanation has been that those eligible are resistant to receiving preventive health care, but a new study published in JAMA and led by researchers at Mass General Brigham indicates otherwise.

Study shows how individual neurons process probability, magnitude and risk of rewards

Researchers have gained a new understanding of how the brain processes reward and risk information. A study by neuroscientists Raymundo Báez-Mendoza from the German Primate Center (DPZ)—Leibniz Institute for Primate Research in Göttingen and Fabian Grabenhorst from the University of Oxford shows how nerve cells in the amygdala not only encode the probability and magnitude of rewards, but also dynamically process this information to predict value and risk.
