A neural “off-switch” for pain documented

From BoingBoing:

In Endogenous adenosine A3 receptor activation selectively alleviates persistent pain states, a paper in Brain by researchers led from the St Louis University Medical School, scientists document their work in switching off neural pain pathways by activating an adenosine receptor.

Pursuit and restraint raise police officers’ risk of sudden death

From Reuters:

Police officers are at increased risk for sudden cardiac death when performing stressful duties like chasing, restraining or fighting with suspects, researchers say.

Sudden cardiac death is up to 70 times more likely during those kinds of stressful activities, compared to when police officers perform routine duties, according a new study of U.S. law enforcement deaths.

‘Stroke robot’ helps improve treatment for stroke patients

From AZFamily:

The robot fills a critical need in stroke diagnoses, because there is a shortage of stroke doctors in this country, Dr. Zach explains. “To have a stroke doctor available in every Emergency Department is just physically impossible,” he explains. “So we are all over and scattered. So if a patient is brought into a center and they don’t have a stroke doctor, it becomes a problem.“

With his IPad, Dr. Zach controls the robot’s two cameras, “One of these cameras is a fish-eye camera so it shows us a really broad view of the entire room, and we get a very large visual field with that,” he explains. “So we are able to ask the patient things like, is there a clock in the room, and there is one over there, and we will be able to see it even though the camera is pointing over this way, you know, and we will be able to know whether the patient can see to that side or not. On the other hand the other camera is a very high quality zoom camera. We can actually zoom in on somebody’s pupil and actually check the pupil reactivity, see if the eye movements are ok.”

He can also read vitals on the screen, and follow the patient to a CT scan. “I will see the pictures come up on the CT scan hot off the presses,” he says.
