Sticking to Neural Tissue

Posted March 26, 2017 12:00 AM by Engineering360 eNewsletter

The ability to interface with neural tissues is enabling a new range of health interventions. Researchers have developed a method for effectively connecting electrodes to neural tissue. This opens the door for advances in pacemakers, deep brain stimulators for treating Parkinson's disease, cochlear implants, functional artificial limbs, and smart contact lenses.

Life-Saving Breath

We have all been in contact with foul-smelling breath before; whether it was your own, a significant other’s, or maybe the breath of a close-talking stranger. Surprisingly, that scent might carry valuable information about your health…and that information might prove to be life-saving.

A “breathalyzer” device, which is described in a study published in the journal ACS Nano, has been developed to detect diseases by simply measuring the user’s breath.

The study operates under the idea that every disease has a “breathpoint,” meaning that certain smells, or the absence of certain smells, might hint at the presence of particular diseases in the body.

The study, which tested over 1,400 participants (both sick and healthy) from five different countries, identified over 100 chemical compounds that are exhaled with each breath. Of the 100, 13 of those chemical compounds were associated with specific diseases. An “artificially intelligent” nanoarray was used to measure the concentrations of the chemicals. If the concentrations were too high or too low, it was an indication that something might be wrong. That data was further analyzed by another “artificially intelligent” system that looked at characteristics such as age and gender in addition to other factors that might contribute to the presence of specific diseases.

Although it is in the early stages of development, the device could identify each participant’s disease with 86 percent accuracy. While that percentage is not accurate enough to make the device a reliable diagnostic tool, it does show promise.

The idea that you can detect disease from simply smelling a person’s breath is not new. It was an ancient practice to smell other forms of bodily excrement to detect disease. In similar studies, it was thought that people who presented with breath that smelled like rotten apples suffered from diabetes and that people who presented with fishy-scented breath suffered from a form of liver disease.

Some of the diseases that can be diagnosed using the breathalyzer include lung cancer, irritable bowel syndrome, and multiple sclerosis. Others include different types of cancer, Crohn’s disease, ulcerative colitis, two kinds of Parkinson’s disease, pulmonary arterial hypertension, pre-eclampsia, and chronic kidney disease.

The clear benefits of testing for diseases in this noninvasive way are significant. The device could save lives, noting the presence of disease before a patient is symptomatic. And because taking a breathalyzer is seemingly painless, it might encourage patients to test for diseases earlier now that they can avoid what are often pretty painful diagnostic tests, as can be the case for diseases like cancer.

And while the device is portable in its current form, developers are hoping to make the device even more accessible by connecting it in some way to standard smart phones.

Researchers Generate 3D Virtual Reality Models of Unborn Babies

Posted December 20, 2016 12:00 AM by Engineering360 eNewsletter

Parents may soon be able to watch their unborn babies grow, thanks to technology that transforms MRI and ultrasound data into a 3D virtual reality model of a fetus. An MRI provides high-resolution fetal and placental imaging with excellent contrast.

Green Light for First Artificial Pancreas

Posted November 10, 2016 12:00 AM by Engineering360 eNewsletter

A hybrid, closed-loop insulin delivery system, dubbed the first artificial pancreas, recently received U.S. Food and Drug Administration approval. Developed by Dublin, Ireland-based Medtronic, the MiniMed 670G automatically monitors blood glucose and administers appropriate basal insulin doses for patients aged 14 years and older with type 1 diabetes. The system comprises a subcutaneously worn continuous monitor that measures glucose levels every five minutes, an insulin pump strapped to the body, and an infusion patch connected to the pump with a catheter that delivers insulin. Unlike previous versions, the MiniMed responds to both low and high blood glucose levels.
