Microchip Could Replace Osteoporosis Shots

Peter Dazeley/Getty Images(BOSTON) -- A microchip could one day change the way many of the 10 million Americans living with osteoporosis manage their symptoms.

One of the greatest challenges of treating osteoporosis by injection is remembering to take the medicine. But a new experimental implantable microchip that releases medication makes it possible to set it and forget it.  

In a first of its kind study, Massachusetts researchers implanted the experimental microchip in the waistline of seven women with osteoporosis. The chip released precise dosages of the osteoporosis drug teriparatide, commonly known as Forteo, either prescheduled or triggered remotely by radio communication.

“It enables telemedicine, in which physicians can keep track of their patients and modify as needed,” said Robert Farra, president and chief operating officer at Michochips Inc. in Waltham, Mass., which makes the experimental microchip and funded the study.

The daily injections increased bone formation in all seven women, according to the study published Thursday in Science Translational Medicine.

The chip, equivalent to the size of a computer flash drive, remained in place for four months. The women didn’t even feel the chip and they experienced no side effects, according to the researchers.

The women were auto-injected with the medication daily for up to 20 days.

These women may have been given more consistent doses compared to standard self-delivered injections, according to the study.  However, the study did not compare the participants’ doses and quality of life to those who use standard injections.

Although this preliminary study tested the microchip device on only seven women, the researchers said it sets up more efficient ways for patients to self-administer their own medication, and even for doctors to better monitor their patients’ treatments.

The microchip is not currently approved by the U.S. Food and Drug Administration. Further tests still need to prove it is just as safe and effective in a larger group of people.

Microchip Provides One-Hour Tumor Diagnosis at Patient's Bedside

Photo Courtesy - Getty Images(BOSTON) -- A recent study shows that a microchip developed by scientists can be plugged into smartphones and provide an accurate diagnosis of cancerous tumors within an hour, according to the journal Science Translational Medicine.

The microNMR chip requires only small amounts of the patient's tissue and measures proteins and other chemical compounds in tumors using magnetic nanoparticles to make the diagnosis.

Researchers in the study were pleased to find that the less-invasive chip detection proved to be both fast and accurate.

"It was a nice surprise just how well it worked with all the protein markers.  One of our big goals was not only to be able to tell patients they have cancer as accurately as possible, but as quickly as possible," said study co-author Jered B. Haun, a postdoctoral researcher at Massachusetts General Hospital in Boston.

Researchers say that, in contrast, the standard methods for pathology typically take up to three or more days to produce a diagnosis with only 84-percent accuracy.

Haun expects that the chip will also be inexpensive to produce.

"Like cell phones in general, the more you make the cheaper they get," he said. "It's not an expensive device at all."
