A team led by researchers at the University of Bath say they have invented artificial neurons that can be helpful in a variety of ways, including controlling prosthetic limbs. The artificial neurons send out signals just as quickly as natural brain cells, the researchers said.

Veterans, active-duty troops and first responders dealing with trauma and chronic pain are finding some relief using virtual reality through a program at the James A. Haley Veterans' Hospital in Tampa, Fla. Patients put on headsets and are transported to environments that help them relax.

A small study of older male athletes suggested regular exercise during adulthood may protect muscles from the effects of aging, researchers reported in the Journal of Applied Physiology. The study compared inflammatory responses following exercise in the elderly athlete group with athletes in their 20s and a group of healthy but sedentary older men, and it found similar signs of low inflammation in the two active groups and signs higher inflammation in the sedentary men.

A study published in the Journal of Diabetes and its Complications found that adults with diabetes who've had at least one hypoglycemic episode within three years of their diabetes diagnosis had 1.46 times increased risk of frailty compared with patients with diabetes and no history of hypoglycemia. Using data from 10,540 patients, the researchers also found that a history of hypoglycemia was linked to a 1.462 times greater mortality risk.

The application of technology, not the technology itself, is disrupting military and veterans' health IT by reducing disruptions elsewhere along the care delivery continuum, such as by streamlining care coordination through integrated electronic health records and by minimizing interruptions for clinicians, says Neil Evans, connected care officer at the Veterans Health Agency. "Technology itself is not disruptive. It is the application of technology to impact people's lives that actually matters," Evans said.

Virginia Gov. Ralph Northam has directed the state's Medicaid director to halt negotiations with the Trump administration on implementation of work requirements in the program, and the state has asked the CMS to stop the approval process. The requirements enabled Northam to gain enough Republican support for expanding eligibility in the state, but the Legislature has since been taken over by Democrats.
