Nano-patch stores medical information under the skin

Every year, a lack of vaccination leads to about 1.5 million preventable deaths, primarily in developing nations. One factor that makes vaccination campaigns in those nations more difficult is that there is little infrastructure for storing medical records, so there’s often no easy way to determine who needs a particular vaccine. Researchers at the Massachusetts Institute of Technology (MIT)…

Pioneering cardiology

Implantable cardiac monitor gets diagnosis in just three days

It started as a fairly typical case: The 79-year-old patient had suffered unexplained dizziness for years. To diagnose why, the cardiology team at Sweden’s Kalmar Hospital performed echocardiograms, Holter ECGs and other tests. However, these tests showed normal sinus rhythm and thus were inconclusive. Dr Hendrik Schreyer, Dr David Olsson and Professor Jörg Carlsson decided to use…
