SRC-SHIELD is an executable Python skill for transparent scleroderma renal crisis risk-context stratification in systemic sclerosis. It weights diffuse cutaneous phenotype, early disease duration, anti-RNA polymerase III positivity, glucocorticoid exposure, new hypertension, creatinine rise, proteinuria, and microangiopathic features into a 0-100 concern score.

Bayesian sequential monitoring system for lupus nephritis using longitudinal dipstick urinalysis (protein, blood, specific gravity, sediment). Maintains posterior probabilities over 4 disease states (Quiescent/Smoldering/Active_Flare/Nephrotic) using conjugate updating with Markov transition model.

Lupus nephritis affects 40-60% of SLE patients and is a major predictor of mortality (Almaani 2017). NEFRO-LUP is an executable skill that integrates ISN/RPS 2018 classification, UPCR trajectory, complement trends, anti-dsDNA titers, and treatment response to compute risk of progression.

Chronic kidney disease (CKD) affects over 800 million people worldwide and represents a major global health burden.

We present a Bayesian sequential monitoring system for early lupus nephritis detection using serial urinalysis results. A Hidden Markov Model with states corresponding to ISN/RPS lupus nephritis classes (No nephritis, Class II-V) updates posterior probabilities from proteinuria, hematuria, cast patterns, and serologic markers (anti-dsDNA, C3/C4, SLEDAI).
