Less Macular Pigment Linked to Disability Glare in Glaucoma
Lower macular pigment optical density (MPOD) is associated with glare-associated visual function and central visual field loss in patients with open-angle glaucoma, researchers report. Reuters Health Information
Swallowable Flexible Sensor to Detect Stomach Movements
Scientists at MIT have developed a flexible sensor that patients can swallow. The sensor sticks to the stomach wall and can relay information about stomach peristalsis. This could help doctors to diagnose disorders that slow down the movement of food through the gastrointestinal tract, or monitor food intake in obese patients. The research team wan (Read more...)

Repeal MIPS, Medicare Advisors Say in SGR Deja Vu
The Medicare Payment Advisory Commission urged Congress to junk the SGR formula in 2011. Now most of the replacement system is under fire. Medscape Medical News
Squeezing Cancer Cells Through Tiny Holes for Diagnostic Uses
The stiffness of a cell is often an indicator of whether it is healthy or cancerous, and the so-called mechanotype, a phenotype based on cell mechanics when squeezed, is indicative of other properties of cells. Being able to easily measure how a cell deforms when under pressure has great potential for diagnostic purposes. Now the […]
Optometry Meeting Spotlights Ocular Surface Disease
The role of the retina in neurological diseases and new concepts in ocular surface disease will headline special symposia at the American Academy of Optometry’s annual conference. Medscape Medical News
Tiny Flexible, Embeddable Temperature Sensor to Monitor Food, Drugs, Medical Devices
At ETH Zurich in Switzerland, researchers have developed tiny new biodegradable sensors that can measure the temperature of things they’re embedded in. The technology is primarily designed to help monitor food safety, but will certainly also be useful for keeping track of temperature sensitive medications and medical devices. The core goal of (Read more...)
Rapid Ascent to High Altitude Alters the Retina
Significant increases in retinal nerve fiber layer (RNFL) thickness occur after rapid ascent to a high-altitude environment and can lead to other pathological changes, researchers from China report. Reuters Health Information
Nobel Prize in Physiology or Medicine 2017 Awarded for Research Into Circadian Rhythms
The 2017 Nobel Prize in Physiology or Medicine has just been announced, and Jeffrey C. Hall, Michael Rosbash, and Michael W. Young are the winners. The scientists explained the workings of the circadian rhythm, a mechanism that is present in plants and animals. Seemingly and forever, the whole living world automatically adjusts to the changes [&hel (Read more...)
FDA Approves Abbott FreeStyle Libre Flash, a CGM That Requires No Blood Sample Calibration
Abbott won the first FDA approval for a continuous glucose monitor that does not need to be calibrated. What this really means is that many diabetes patients can now say goodbye to having to prick their fingers on a regular basis, being able to replace blood draws completely with the new FreeStyle Libre Flash Glucose […]
3D Printing of Biomaterials Directly Onto Moving Body
At the 2017 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS) in Vancouver, Canada this week, researchers from the University of Minnesota are presenting a system that 3D prints objects directly onto a moving human body. It’s intended to put down layers of biomaterials that have been developed in the recent years (Read more...)
Eyedrops for Diabetic Retinopathy Possible in the Future?
Contrary to hypothesis, neurodysfunction preceded microvascular impairment in only a minority of diabetic-retinopathy patients, but in that subgroup, neuroprotective eyedrops arrested disease progression. Medscape Medical News
Low LDL Target, No Clinical Gain in Non-CAD Diabetes: EMPATHY
Statins aimed at reducing LDL-C to less than 70 mg/dL didn’t cut cardiovascular events, but an intriguing post hoc finding suggests there may yet be benefit, in this trial of patients with diabetic retinopathy. Medscape Medical News
Bariatric Surgery May Reduce Retinopathy Risk, Progression
Roux-en-Y gastric bypass reduced diabetic retinopathy risk regardless of postsurgery diabetes status in a two-phase trial; a second study confirms obesity-related microvascular changes are reversible. Medscape Medical News
J-DOIT3: ‘Aim for Near-Normal Metabolic Parameters’ in Diabetes
UPDATED // The large Japanese DOIT3 trial tells clinicians that optimal lipid, blood pressure, and, glycemic control are important to reduce microvascular and macrovascular complications in type 2 diabetes. Medscape Medical News
Flexible Supercapacitors Hope to Replace Batteries in Medical Implants
Many of the limitations of existing electronic medical implants, such as pacemakers and defibrillators, arise from the internal batteries. The batteries are rigir, requiring the implants to have a strong metal structure that makes them bulky. At Queen’s University Belfast in Northern Ireland researchers have been working on developing superca (Read more...)
