A team of Google researchers has published a paper in the Journal of the American Medical Association showing that Google's deep learning algorithm, trained on a large data set of fundus images, can detect diabetic retinopathy with better than 90 percent accuracy.  "These results demonstrate that deep neural networks can be trained, using large data sets and without having to specify lesion-based...

Does your Fitbit actually make you less likely to lose weight? Probably not, despite what you may have read recently. That was the question a number of major consumer-focused media outlets were asking after a new study in JAMA seemed to show just that.

That was the question that concerned two recent publications: a small study of patients with low health literacy conducted by the Commonwealth Fund, and a research letter published in JAMA looking at digital health usage by a cohort of 7,000 seniors over four years. The Commonwealth Fund study observed 26 low-income...

As their famous rallying cry states, the patients behind the Nightscout project for creating a do-it-yourself mobile technology for diabetes management are not waiting for approval from the FDA. But that doesn't mean they aren't seeking it, or that they haven't been in contact with the regulatory organization to make sure Nightscout is as safe as it can be. In a new editorial published in the...

A study of eight leading telemedicine companies shows that, for a number of common conditions, remote video and telephone visits are equally accurate, both are more accurate than webchat, and accuracy of diagnoses and adherence to best practices for in-person care varied greatly from company to company. In the study, published in the Journal of the American Medical Association, UCSF-affiliated...

A new paper published yesterday in JAMA Internal Medicine shows that, when it comes to measuring energy expenditure, many leading fitness trackers have a margin of error of about 200 calories per day in either direction. The study was conducted by Japanese researchers led by Haruka Murakami from the National Institute of Health and Nutrition in Tokyo. Nineteen participants, aged 21 to 50, wore 12...

A relatively large randomized control trial in Australia has shown that a text messaging program can improve not only health behaviors, but actually affect health outcomes. The 2-year study of 710 patients with coronary heart disease, published in the Journal of the American Medical Association showed that six months of a text messaging intervention produced significant reduction in cholesterol,...

Last week, JAMA Internal Medicine published a two-page research letter by the Rand Corporation that played into a national conversation about the efficacy of telemedicine -- specifically Teladoc, a company which is both about to IPO and embroiled in a potentially precedent-setting legal battle with its home state of Texas over whether the Texas Medical Board has the right to regulate the practice...
