Non-invasive diabetes monitoring through breath analysis
http://www.news.pitt.edu/news/diabetes-breathalyzer University of Pittsburgh professor Alexander Star, Dan Sorescu of the National Energy Technology Laboratory, and graduate student Mengning Ding have demonstrated sensor technology that could simplify the diagnosis and monitoring of diabetes through breath analysis alone. The researchers used a “sol-gel approach,” a method for using small molecules (often on a nanoscale level) to produce solid materials.…

Medical device data shared via ultrasound, real-time treatment enabled
http://www.buffalo.edu/news/releases/2013/05/0570.html Navy sonar technology is being miniaturized by University at Buffalo professor Tommaso Melodia to be applied inside the human body to treat diseases like diabetes and heart failure in real time. A network of wireless body sensors that use ultrasounds could be used to wirelessly share information between medical devices implanted in or worn by diabetic/heart failure patients. Previously, researchers focused…

Nanotube sensor detects glucose in saliva
http://www.technologyreview.com/view/514456/carbon-nanotube-sensor-detects-glucose-in-saliva/ A team led by Mitchell Lerner at the University of Pennsylvania has developed a carbon nanotube based transistor that can detect glucose levels in body fluids, including saliva. The nanotubes are coated with molecules of pyrene-1-boronic acid, which makes them highly sensitive for glucose detection. When exposed to glucose, the nanotube transistor’s current-voltage curve changes,…

A “bionic pancreas” for diabetes management
http://www.huffingtonpost.com/riva-greenberg/diabetes-clinical-trial_b_3110140.html The bionic pancreas consists of three pieces of hardware. There’s an iPhone with an app that contains the system’s control software and algorithm and a continuous glucose monitor (CGM). The CGM’s sensor/transmitter, worn under the skin, streams glucose (blood sugar) data to two connected infusion pumps. One delivers insulin to lower blood sugar and…

Sensors detect diabetic foot ulcers early
Two new sensor-based early detection tools for diabetic foot ulcers are being developed. http://www.express.co.uk/life-style/health/383644/The-alarm-that-can-save-limbs Orpyx Medical Technologies has developed a wristwatch and shoe insert. An insole is designed to support the foot, with three separate foam layers. Eight tiny electronic sensors are packed in the top of the insole so that they rest against thesurface of the foot once the shoe has been put on. These sensors are programmed to…

Self tracking for diabetes — more efficient, still complicated
http://www.theatlantic.com/health/archive/2013/04/the-diabetics-paradox/274507/ Diabetes patients have been self monitoring for years. Advances in mHealth have made the process more efficient, though still complicated. The iPhone can improve the functionality of glucometers; last month the FDA approved LifeScan’s VerioSync glucometer; the device automatically sends blood sugar levels to an iPhone via Bluetooth (fewer steps mean fewer mistakes and less anxiety).…

A move toward aggregating health data from various devices and apps
http://gigaom.com/2013/03/15/tictrac-emerges-to-help-make-health-tracking-more-mainstream/ It seems that every day a new app or device promising the ultimate in health or fitness monitoring enters the market. A startup has created a personal analytics dashboard which gives people a big picture view of their own aggregated data and underlying patterns, helping them make sense of the numbers.

The Relationship of Sugar to Population-Level Diabetes Prevalence
http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0057873 Increased sugar consumption leads to increased diabetes prevalence. One solution is to reduce sugar consumption, but this is difficult to implement in a western diet. It is best to combine the consumption of high fiber foods such as oatmeal, oat bran, beans and legumes with the consumption of high sugar foods.
