American Life in Realtime: a benchmark registry of health data for equitable precision health.
Ritika R Chaturvedi et al. Nature medicine 2023 2

Emerging precision health methods use large-scale person-generated health data from smartphones and wearables to better characterize and, ultimately, improve health and well-being through strategies customized to individual context and need3,4. Applying artificial intelligence and machine learning to person-generated health data allows unprecedented assessment of recursive, networked and latent associations between everyday life and health, including social, structural and environmental exposures, behaviors, biometrics, and health outcomes.

Passive monitoring by smart toilets for precision health.
T Jessie Ge et al. Science translational medicine 2023 2 (681) eabk3489

Precision health is an approach to prevent, diagnose, and monitor disease using information gleaned from an individual’s biological information. Passive monitoring in a smart home setting, where appliances and devices are connected and controlled automatically, may provide such biological information. Whereas wearable health sensors must be actively applied and require a certain amount of human intervention, a sensor that performs passively and noninvasively can collect valuable health data in the background of everyday life. Of the possible locations in a smart home, the bathroom, and more specifically the toilet, is particularly well suited for such passive sensors.

Association of wearable device-measured vigorous intermittent lifestyle physical activity with mortality
E Stamatakis et al, Nature Medicine, December 8, 2022

Here, we examined the association of VILPA with all-cause, cardiovascular disease (CVD) and cancer mortality in 25,241 nonexercisers (mean age 61.8?years, 14,178 women/11,063 men) in the UK Biobank. Over an average follow-up of 6.9?years, during which 852 deaths occurred, VILPA was inversely associated with all three of these outcomes in a near-linear fashion. Compared with participants who engaged in no VILPA, participants who engaged in VILPA at the sample median VILPA frequency of 3?length-standardized bouts per day (lasting 1 or 2?min each) showed a 38%–40% reduction in all-cause and cancer mortality risk and a 48%–49% reduction in CVD mortality risk.

Prospective evaluation of smartwatch-enabled detection of left ventricular dysfunction
ZI Attoa et al, Nature Medicine, November 14, 2022

Although artificial intelligence (AI) algorithms have been shown to be capable of identifying cardiac dysfunction, defined as ejection fraction (EF) = 40%, from 12-lead electrocardiograms (ECGs), identification of cardiac dysfunction using the single-lead ECG of a smartwatch has yet to be tested. We digitally enrolled 2,454 unique patients from 46 US states and 11 countries, who sent 125,610 ECGs to the data platform between August 2021 and February 2022; 421 participants had at least one watch-classified sinus rhythm ECG within 30?d of an echocardiogram, of whom 16 (3.8%) had an EF?=?40%. The AI algorithm detected patients with low EF with an area under the curve of 0.885.
