A mobile eye tracker may be able to estimate the cognitive load of lower-limb prosthesis users by measuring pupil diameter and gaze fixation time in relation to subjective ratings of cognition, according to a study published in Clinical Biomechanics. Researchers recorded eye tracking data and kinematics as study participants completed physical tasks while focusing their gaze on a certain point for as long as possible, then compared the results to their assessment of cognitive load.

Cedars-Sinai researchers have used neuroprosthetics technology to harness the power of the cerebellum to improve patients' ability to manipulate robotic limbs, according to a study published in Science Advances. "There is a lot of buzz about neuroprosthetic technology, but there are still many unsolved problems," said David Underhill, biomedical sciences department chair at Cedars-Sinai. "This study suggests that some of those could be resolved by involving the cerebellum as well as the motor cortex to help patients gain use of neuroprosthetic devices more quickly and improve their ability to control them accurately."

There is more to the story of a patient whose death certificate cites sepsis due to bone infection, writes Dr. Lindsay Ryan. The man was a victim of "'end-stage poverty" whose lack of a home caused him to refuse a necessary amputation.

Young women often delay seeking medical care for breast cancer symptoms, waiting an average of two weeks before seeing a physician, which can be risky due to the potential for later-stage diagnoses and more aggressive cancers. Factors contributing to delays include lack of concern, waiting for reassurance from others, difficulty accessing care, and competing priorities in their lives, according to the study.

A KFF analysis found that at least 20.1 million people have lost Medicaid coverage and 43.6 million had their coverage renewed in 50 states and Washington, D.C., as of April 11, one year after the redetermination process restarted. Sixty-nine percent were disenrolled due to procedural reasons, and Texas, California, Florida and New York recorded the highest numbers of disenrollments among states.

Twelve-year-old Yana Stepanenko ran the Boston Marathon for the first time Monday after losing her legs in a Russian strike on a railway station in Ukraine two years ago. Her effort also was a fundraiser to get a sports prosthesis for a Ukrainian fighter.

Archery became Bobby Griffith's athletic outlet after his leg was amputated when he was crushed between two cars while trying to help a stranded motorist. Now, Griffith, who coaches children in archery, has been selected to join Team USA Archery and compete at the Parapan American Championship in Brazil, which starts Sunday.

Leadership confidence is about improving yourself, but not on the backs of others. Confidence comes from within and is "an unshakeable sense of self, which requires consistent and continued dedication to your values, goals and personal self-worth," writes executive coach Joel Garfinkle, who offers five ways to build your confidence without throwing your weight around.
