Study finds wearables may help detect serious illness | MobiHealthNews

Led by geneticist Dr. Michael Snyder, researchers looked at 2 billion measurements from 60 people. Study participants wore between one and seven commercially available activity trackers (including Masimo, Basis and Scanadu) and other monitors, which were compared to the university’s standard clinical vital signs monitors. The devices collected 250,000 measurements per day, and researchers worked to establish a baseline range of values for each participant by collecting essential data like weight, heart rate, skin temperature, sleep, activity and caloric burn and exposure to gamma rays and X-rays. From there, the Stanford team was able to monitor deviations from each person’s normal baseline and associate the changes with environmental conditions (like flying in an airplane), illness, and other health-impacting factors. The team found two health-related observations – wearables were useful in identifying the onset of Lyme disease and inflammation, allowing them to build an algorithm for personalized disease detection using wearable sensors. They also found the sensors can reveal physiological differences between insulin sensitive and insulin-resistant people, meaning they could have the potential to help identify those at risk for type 2 diabetes.

Modest physical activity associated with improvement in markers, data suggests -- ScienceDaily

Researchers at the Boston University School of Medicine (BUSM) sought to examine the relationship of physical activity and inactivity, to insulin resistance and biomarkers of inflammation. Participants were asked to wear accelerometers during the day to estimate the amount of physical activity, as well as time spent being less active ("sedentary time"). These measurements were then compared to chemical markers of insulin resistance, inflammation and metabolism found in blood. They found that increased levels of physical activity (below what is required for weight loss) were associated with decreased insulin resistance as well as biomarkers of inflammation. The researchers also demonstrated that among individuals who spent more time sedentary, their blood contained higher levels of leptin, a chemical produced in fatty tissue that causes satiety, and FABP4 (fatty acid binding protein 4), a protein involved in the transport of fat molecules.

How to Avoid Becoming Diabetic

For almost a decade, Swedish GP Dr. Andreas Eenfeldt has been counseling his pre-diabetes, T2 diabetes, and obese patients to switch to a low-carb, high-fat diet. “In weeks and months they got better, their diabetes reversed and they could get off drugs,” said Dr Eenfeldt, who in 2007 started a non-commercial Swedish website, dietdoctor.com. In 2010 his book Low Carb High Fat Food Revolution became a Swedish bestseller and was translated into eight languages. In 2011, he started the English dietdoctor.com site.
