Circadian phase in high-school students: weekday-weekend shifts and relationships to other sleep/circadian characteristics
Hasler et al.
The finding, in our words
High-school students show substantial circadian phase shifts from school week to weekend, creating social jetlag that is most marked in those with later phases who also exhibit the greatest weekend catch-up sleep. Self-reported proxies such as questionnaires and actigraphy-based midsleep correlate poorly with biological circadian phase measured by salivary melatonin, underscoring the need for direct biomarker assessment in decentralised sleep diagnostics.

In a 14-day study of youth with neurodevelopmental conditions and chronic pain, multimodal in-home monitoring achieved good accelerometer wear compliance (77% wore devices for at least 7 days) and moderate survey engagement, but adherence to salivary cortisol sampling was low at 28% after excluding protocol violations and dry swabs. Families reported high overall satisfaction and willingness to participate again, highlighting that remote sampling protocols in pediatric populations require iterative tailoring to improve biospecimen collection adherence.

Acutely concussed youth studied at home showed longer sleep latency and greater fatigue than controls, with altered overnight cortisol dynamics and lower bedtime melatonin; these home-based saliva and actigraphy measures highlight decentralised endpoints for acute concussion care.

This review establishes that microsampling across blood, saliva, urine and stool matrices offers validated workflows and regulatory recognition for human biomonitoring comparable to conventional methods. It finds that these decentralised approaches enhance participant acceptability and enable screening in remote or low-resource settings.
This study demonstrates that a memristor sensor can identify distinct electrical signatures in saliva and urine corresponding to different ovulation phases, suggesting a potential route for noninvasive home fertility monitoring.
Older adults with and without cognitive impairment were motivated to participate in longitudinal remote sleep research, finding it acceptable when device burden was low, usability high, and adequate support enabled routine integration. Varying cognitive task content and allowing timing flexibility reduced fatigue, while diverse recruitment remains needed for equitable representation in decentralised dementia trials.
