Biomarkers could tell doctors when concussed athletes are safe to compete

Biomarkers could tell doctors when concussed athletes are safe to compete | healthcare technology | Scoop.it

A protein in the central nervous system could provide a useful tool for diagnosing concussions and allow doctors to assess when it is safe for athletes to return to competition.


Swedish researchers have found, through examining studies in sporting injuries, that a protein in the central nervous system could provide a tool for diagnosing concussions. They published their results in JAMA Neurology.


Previous studies have measured changes in the levels of protein biomarkers present in cerebrospinal fluid or blood in athletes who participate in contact sports.


Certain biomarkers - neuron-specific enolase, S-100 calcium-binding protein B, neurofilament light and total tau (T-tau) - have been shown to increase in boxers, correlating with the number and severity of head blows received. After a rest from boxing, these biomarkers return to normal levels.

Could A Blood Test Predict When You Will Die?

Could A Blood Test Predict When You Will Die? | healthcare technology | Scoop.it

Online quizzes that predict when you’re going to die were popular for a while, but now there is an actual test that could uncover your expiration date. 17,000 samples of blood from Finland and Estonia were tested to uncover which of 100 biomarkers were present in people that died within five years. Researchers turned up four specific biomarkers linked to a higher risk of dying from heart disease, cancer, and other illnesses.

The four culprits responsible for early death include albumin, alpha-1-acid glycoprotein, citrate, and the size of low-density lipoprotein particles. Albumin has already been linked to early death in the past, but the other three have been under the radar until now. Scientists made sure there there were no other contributing factors either, such as old age, obesity, cholesterol levels, or alcohol use, amongst others.
