Harvard team uses bacterial enzyme coating to extend life of implantable devices

The body’s response to foreign material–forming blood clots and becoming inflamed–can prevent blood-contacting implants like stents and heart valves from working properly.  While the only recourse is to replace the device, Harvard scientists have developed a new biochemical method to coat these devices to preserve their function.

Experts worry insulin getting too expensive for many in U.S. and worldwide

Drugmakers have made great strides coming up with new treatments for diabetes as the disease gallops across the globe.  However, healthcare professionals are concerned that hormone insulin meds, often the key treatment, are getting too costly for many patients, even in the U.S. In developing countries, they say engineered insulin is automatically out of reach of many people while supplies of older, but cheaper, human insulin are becoming scarce.

Feds roll out new tool for mobile health app development geared toward security

Mobile health app developers have struggled to figure out whether their technology will pass muster with regulators.  Now, feds want to take out some of the guesswork.  The FTC and FDA are rolling out a new web-based tool for companies making mobile health apps that helps them understand which laws and regulations apply to their products, especially regarding security.

Plastic-softening chemicals in medical devices could lead to brain problems in kids

Scientists have found that children hospitalized in intensive care units are more likely to develop attention deficit disorders further down the road, and now, they’ve uncovered a link.  Researchers in Belgium saw that plastic-softening chemicals in medical devices can lead to neurocognitive issues in kids.

Parkinson’s could potentially be detected by an eye test

Researchers may have discovered a method of detecting changes in the eye that could identify Parkinson’s disease before its symptoms develop.  Scientists at University College London (UCL) say their early animal tests could lead to a cheap and non-invasive way to spot the disease.

Harvard researchers tackle football player health with new smartphone app

Scientists have focused on developing new tech to address brain injuries in football players, but now, a group of researchers is thinking bigger picture.  Researchers at Harvard University are launching a smartphone app through Apple’s ResearchKit that takes a broad look at players’ health after they leave the field.
