FDA approves blood test that predicts risk of coronary heart disease

By - December 22, 2014 1 Picture
Coronary heart disease (CHD) kills more than 385,000 people in the United States each year, and more than half of those who die suddenly have no previous symptoms. A new blood test that could reduce CHD-related illness and mortality by predicting the risk of future heart disease has been cleared by the US Food and Drug Administration (FDA). The PLAC Test for Lp-PLA2 screens for cardiovascular inflammation which can lead to a build up of rupture-prone plaque and result in a heart attack or stroke. Read More

SensiumVitals could allow for near-constant observation of patients' vital signs

By - August 5, 2014 3 Pictures
A new system developed by the Toumaz Group may hold the key to improving the level of life-saving attention received by patients, providing two-minute updates on their vital signs 24 hours a day with the use of a comfortable, wireless sensor pad. The equipment, known as SensiumVitals, is claimed to be so portable and convenient that it could even be used in the future to provide hospital-level observation to individuals in the comfort of their own homes.

FDA gives approval for DEKA prosthetic arm controlled by muscle impulses

By - May 12, 2014 3 Pictures
Prosthetics have come a long way in recent years, with many artificial limbs incorporating advanced robotic and cybernetic systems that include everything up to and including mind control. Unfortunately, for all these advances, the lack of prosthetics capable of complex motor control means that most users see them as tools rather than replacement limbs. However, that may be changing as the US Food and Drug Administration (FDA) has announced approval for marketing of the DEKA Arm system, the first prosthetic arm set to hit the market that translates signals from a patient’s muscles to carry out complex tasks.

Electric "thinking cap" helps people learn from their mistakes

By - March 27, 2014 7 Pictures
Transcranial direct current stimulation (tDCS) has become a widely used technique for reaching into a person's brain and altering the way in which it functions. Vanderbilt psychology Professor Geoffrey Woodman and graduate student Robert Reinhart have just published the results of a new study in the Journal of Neuroscience in which they found that tDCS stimulation of the mediofrontal cortex for a period of minutes can change one's ability to recognize and learn from error for a period of several hours.

XStat treats bullet wounds with tiny injectable sponges

By - February 11, 2014 5 Pictures
Uncontrolled hemorrhage (bleeding out) is responsible for 80 percent of combat deaths. About the same proportion of those who die after being evacuated to a medical treatment facility also die of hemorrhage, usually associated with deep arterial wounds that cannot be treated using tourniquets – people die because we can't plug a simple hole. Now RevMedX, a small Oregon startup, has developed an alternative approach to treat such potentially survivable injuries. Read More

Argus II becomes first "bionic eye" to gain approval for sale in U.S.

By - February 18, 2013 4 Pictures
While the word prosthesis usually evokes images of artificial legs, arms, and these days even sophisticated thought-controlled hands, an entirely new class of replacement body part has now become a reality – the bionic eye. One of the pioneers in this field is California-based Second Sight and the company has now announced that its Argus II System has received U.S. market approval from the Food and Drug Administration (FDA).

GE Silent Scan turns down the volume on MRI scanners

By - January 6, 2013 1 Picture
GE Healthcare has introduced a new data acquisition technology designed to improve patient comfort by largely eliminating the horrible noise generated during an MRI scan. Conventional MRI scanners can generate noise levels in excess of 110 dBA (creating a din that sounds like a cross between a vehicle's reverse warning horn and a Star Trek phaser) but GE says its new Silent Scan MRI technology can reduce this to just above background noise levels in the exam room.
