Abbott’s next-gen FreeStyle Libre wins CE Mark, as announced by Abbott today, October 1, 2018.
The FreeStyle Libre 2 system includes alarms to alert the user when it detects low and high glucose and an alarm to notify the user when the sensor can’t communicate with the reader. Users can decide if they want to receive alarms and if they want to be alerted via sound or vibration. Consistent with Abbott’s first-gen FreeStyle Libre monitor, users can also track glucose trends and patterns and view an eight-hour glucose history.
Muscle “switch” may control the benefits of exercise – A biological pathway that boosts either aerobic capacity or muscle growth may offer clues to prevent diabetes … was reported in the Joslin Diabetes Center Newletter, 2 August, 2018.
Some people respond well to both aerobic exercise and strength training, while others don’t. And some of us respond well to only one of those things, but not both. Scientists at Joslin Diabetes Center now have uncovered a surprising molecular “switch” that may help to explain this lack of response to exercise and to give clues to better treatments against diabetes.
“We’ve identified an exercise-activated biological pathway that hasn’t been studied at all,” says Sarah Lessard, PhD, an Assistant Investigator in Joslin’s section of Clinical, Behavioral and Outcomes Research and first author on a paper presenting the research in the journal Nature Communications.
Studying both lab animals and humans, Lessard and her colleagues discovered that a protein called JNK helps to drive response to exercise. If JNK is activated during exercise, the researchers say, that stimulates skeletal muscle growth. If it’s not activated, muscles improve their adaptation for endurance and aerobic capacity.
Released by Close Concerns, 25 September 2018 from the Tandem 2018 Analyst Meeting: Control-IQ launch in summer 2019 with iPump designation; t:sport in 2H20; record Q3 sales of $42-$44 million. That’s a whole bunch of news!
- The Control-IQ hybrid closed loop is still slated for a summer 2019 launch. In a major regulatory shift, the t:slim X2 will be submitted to FDA as the first “iPump” with interoperability in mind – following Dexcom’s lead with the G6 iCGM clearance.
- t:sport – a miniaturized, screenless, wirelessly controlled tubed pump – is expected to launch in 2H20. t:sport will be submitted as an iPump with Control-IQ and iCGM integration, meaning no new clinical data will be needed. The no-screen pump will be controlle via app on a user’s own phone or a separate touchscreen controller. t:sport is half the size of the current t:slim; will switch to a syringe-driven pumping mechanism; and will add wireless charging, water resistance, an on-device bolus button, and an easier fill process. Closed loop will still run if the phone/controller is out of range.

Digital glasses offer hope of sight for vision-impaired was discussed on Leoni Jesner of Israel21c.org on 26 September 2018. This could be a breakthrough technology for those with impaired vision from retinal damage.
ICI Vision’s Orama high-tech glasses are the brainchild of Haim Chayet, an Israeli optic physicist who was originally creating augmented-reality goggles for motorcyclists.
Working alongside a friend who had damaged vision due to a scar on his eye, Chayet realized the technology would have greater impact as an assistive device for many people experiencing vision impairment. Joining forces with two partners in the field and top Israeli eye doctors in an advisory capacity, he launched ICI Vision in 2014.
Orama’s “enhanced vision engine” combines artificial intelligence, eye-tracking software, computer vision and other software and hardware, including a built-in 3D camera, to fill in the gaps from loss of vision and optimize the image in front of the user’s eyes.
The eyewear is personalized to each user through eye mapping, a procedure that establishes the location of healthy retinal cells.
“Once the extent of a patient’s retinal damage has been established, we can build a set of glasses which projects images onto the healthy part of the eye to enhance their central vision,” explains Lotan. “No one else is doing exactly what we do.”
Gut microbes may contribute to depression and anxiety in obesity, according to researchrs at Joslin Diabetes Center, who have now demonstrated a surprising potential contributor to these negative feelings – the bacteria in the gut or gut microbiome, as it is known … reported on the Joslin Diabetes Center newsletter, 18 June 2018.
Studying mice that become obese when put on a high-fat diet, the Joslin scientists found those mice showed significantly more signs of anxiety, depression and obsessive behavior than animals on standard diets. “But all of these behaviors are reversed or improved when antibiotics that will change the gut microbiome were given with the high fat diet,” says C. Ronald Kahn, M.D., co-Head of the Section on Integrative Physiology and Metabolism at Joslin and the Mary K. Iacocca Professor of Medicine at Harvard Medical School.
“As endocrinologists, we often hear people say that they feel differently when they’ve eaten different foods,” notes Kahn, who is senior author on a paper in Molecular Psychiatry describing the research. “What this study says is that many things in your diet might affect the way your brain functions, but one of those things is the way diet changes the gut bacteria or microbes. Your diet isn’t always necessarily just making your blood sugar higher or lower; it’s also changing a lot of signals coming from gut microbes and these signals make it all the way to the brain.”
