Non-Invasive Capillary Blood Pressure Measurement Enabling Early Detection and Classification of Venous Congestion
Liu et al.
The finding, in our words
A non-invasive opto-mechanical system using photoplethysmography in finger and toe cuffs can measure capillary blood pressure and distinguish between healthy subjects and those with peripheral arterial disease, varicose veins or heart failure. This could enable early detection of venous congestion before overt oedema develops, supporting point-of-care management of cardiovascular conditions.
A paraphrase to the Library’s standard, never the abstract. The source is one link away and is always the authority.
In a Phase 1 crossover study of etrasimod, self-collected blood microsamples yielded pharmacokinetic exposures comparable to conventional venous sampling, both with and without participant practice sessions. Continuous wearable sensors concurrently enabled real-time remote monitoring of safety vital signs and electrocardiograms, demonstrating the viability of hybrid decentralised designs in early-phase clinical trials.
In adults with type 1 diabetes, Dexcom G7 and FreeStyle Libre 3 showed high accuracy during physical activity, whereas the Simplera system was less accurate; this matters for selecting devices in decentralised monitoring.
In progressive multiple sclerosis, higher serum neurofilament light chain levels were associated with reduced daily step counts from wearables, while higher step counts were linked to lower sNfL. A ten percent increase in steps corresponded to a 0.015 decrease in sNfL z-score, suggesting rising sNfL may predict subsequent mobility decline.
The study demonstrates that frequent collection of 10 microlitres of capillary blood, combined with wearable sensor data, enables simultaneous measurement of thousands of metabolites, lipids, cytokines and proteins, revealing individualised metabolic and inflammatory responses to dietary interventions and molecular fluctuations linked to intra-day changes in heart rate, glucose, cortisol and physical activity, supporting dynamic health profiling outside the clinic.
The study found that smartwatch-based adherence monitoring showed consistent concordance over time and may be more reliable than app or pill count methods in measuring treatment adherence in a decentralised setting. This supports the use of wearable devices as objective tools in patient-centric monitoring for decentralised clinical trials.
