Age-related patterns in distal skin temperature during naps

Severine Soltani, Wendy Hartogensis, Patrick Kasl, Stephan Dilchert et autres

STUDY OBJECTIVES: Naps are common worldwide; despite their prevalence, physiological changes during naps are less well-characterized than during nighttime sleep. We aimed to characterize napping patterns and their associated physiological changes across age groups. METHODS: We used longitudinal wearable device data from …

Sleep and temperature data from wearable devices support noninvasive detection of diabetes mellitus in a large-scale, retrospective analysis

Varun K. Viswanath, Shreenithi Navaneethan, Jamison H. Burks, Severine Soltani et autres

BACKGROUND: Diabetes Mellitus is a common, chronic metabolic disorder affecting the cardiovascular system, autonomic nervous system, and sleep quality. Diabetes affects diverse physiological data including heart rate variability, distal body temperature, and sleep duration. We hypothesized that biologically informed features from wearable …

Tesserae

Beth Malory, Stephen Mattingly, Alberto Díaz-Álvarez, Ricky Lee et autres

Project Tesserae was a multi-university research to study how we can sense and better understand workplace performance in the modern, digital age. This study contains a description of the data gathered that is available via a Data Usage Agreement.

Testing the Impact of Intensive, Longitudinal Sampling on Assessments of Statistical Power and Effect Size Within a Heterogeneous Human Population: Natural Experiment Using Change in Heart Rate on Weekends as a Surrogate Intervention

Severine Soltani, Varun Kumar Viswanath, Patrick Kasl, Wendy Hartogensis et autres

BACKGROUND: The recent emergence of wearable devices has made feasible the passive gathering of intensive, longitudinal data from large groups of individuals. This form of data is effective at capturing physiological changes between participants (interindividual variability) and changes within participants over time …

General feature selection technique supporting sex-debiasing in chronic illness algorithms validated using wearable device data

Jamison H. Burks, Lauryn Keeler Bruce, Patrick Kasl, Severine Soltani et autres

Abstract In tasks involving human health condition data, feature selection is heavily affected by data types, the complexity of the condition manifestation, and the variability in physiological presentation. One type of variability often overlooked or oversimplified is the effect of biological sex. …

Utilizing Wearable Device Data for Syndromic Surveillance: A Fever Detection Approach

Patrick Kasl, Lauryn Keeler Bruce, Wendy Hartogensis, Leena S. Pandya et autres

Commercially available wearable devices (wearables) show promise for continuous physiological monitoring. Previous works have demonstrated that wearables can be used to detect the onset of acute infectious diseases, particularly those characterized by fever. We aimed to evaluate whether these devices could be …

Elevated body temperature is associated with depressive symptoms: results from the TemPredict Study

Ashley E. Mason, Patrick Kasl, Severine Soltani, Abigail Green et autres

Correlations between altered body temperature and depression have been reported in small samples; greater confidence in these associations would provide a rationale for further examining potential mechanisms of depression related to body temperature regulation. We sought to test the hypotheses that greater …

Correction: Variability of temperature measurements recorded by a wearable device by biological sex

Lauryn Keeler Bruce, Patrick Kasl, Severine Soltani, Varun Kumar Viswanath et autres

Following publication of the original article [1], the authors reported an error in their equal contributions statement. The statement should read: Ashley E. Mason and Benjamin L. Smarr contributed equally and are co-senior authors. The original article [1] has been updated.

Variability of temperature measurements recorded by a wearable device by biological sex

Lauryn Keeler Bruce, Patrick Kasl, Severine Soltani, Varun Kumar Viswanath et autres

BACKGROUND: Females have been historically excluded from biomedical research due in part to the documented presumption that results with male subjects will generalize effectively to females. This has been justified in part by the assumption that ovarian rhythms will increase the overall …
