On this episode of Art Institute Essentials Tour, take a closer look at American Gothic, painted by Grant Wood in 1930. One of the most famous American paintings of all time, this double portrait by Grant Wood debuted at the Art Institute in 1930, winning the artist a $300 prize and instant fame. Wood intended this Depression-era canvas to be a positive statement about rural American values during a time of disillusionment.

Health: Scientists Develop Simple Smartphone App To Detect “Diabetes” With Up To 80% Accuracy (UCSF)

Overall, the algorithm correctly identified the presence of diabetes in up to 81 percent of patients in two separate datasets. When the algorithm was tested in an additional dataset of patients enrolled from in-person clinics, it correctly identified 82 percent of patients with diabetes.  

In the Nature Medicine study, UCSF researchers obtained nearly 3 million PPG recordings from 53,870 patients in the Health eHeart Study who used the Azumio Instant Heart Rate app on the iPhone and reported having been diagnosed with diabetes by a health care provider. This data was used to both develop and validate a deep-learning algorithm to detect the presence of diabetes using smartphone-measured PPG signals.  

Among the patients that the algorithm predicted did not have diabetes, 92 to 97 percent indeed did not have the disease across the validation datasets. When this PPG-derived prediction was combined with other easily obtainable patient information, such as age, gender, body mass index and race/ethnicity, predictive performance improved further.
