Abstract
Blood glucose is one of the most essential parameters in metabolic research. Yet, accurate blood glucose monitoring in mouse models of diabetes is challenging owing to the substantial stress associated with the measurements and the variability in diabetes development among experimental mouse models. This variability requires frequent blood glucose measurements, which provide only intermittent data and may not accurately reflect continuous metabolic changes. Here, to address these issues, we have utilized the Tecniplast DVC system to monitor bedding moisture, enabling the detection of increased urination (polyuria) in mice, a primary symptom of diabetes. Polyuria is a hallmark of (undiagnosed/untreated) diabetes, and we revealed high correlations between bedding moisture and blood glucose during hyperglycemia. Thus, our developed algorithm enhances animal welfare by reducing the need for invasive blood glucose tests and enabling noninvasive, continuous assessment of hyperglycemia onset, progression and severity directly within the mice's home cage. The continuous monitoring of polyuria allows the detailed analysis of temporal and circadian urination patterns and enables assessment of the efficacy of glucose-lowering interventions, which is critical in developing new pharmacological treatments. We propose that this innovative approach of a novel digital biomarker, the Urination Index, offers a substantial advance in the methodology for diabetes research in mouse models, improves animal welfare by reducing the need for invasive blood glucose tests and enhances the reliability of data and the quality of life for the animals involved.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
