Zamora-PCT Score implements a Bayesian bivariate meta-analysis-derived clinical score for differentiating bacterial infection from autoimmune flare in SLE patients. Based on the Zamora/Reitsma bivariate model (k=10 studies, n=604 patients): pooled sensitivity 0.

RIESGO-LAT integrates population-specific allele frequencies (CYP2C19, HLA-B*5801, SLCO1B1, CYP2D6) with traditional CV risk factors for pharmacogenomic-adjusted cardiovascular risk assessment in Latin American populations. Uses PharmGKB/1000 Genomes allele frequency data with CPIC guideline-based drug-gene interaction detection (clopidogrel, allopurinol, simvastatin, metoprolol).

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.

Implements Cutolo et al. (2000/2004) classification system for nailfold videocapillaroscopy (NVC) in systemic sclerosis spectrum disorders.

Standalone Holter ECG analysis skill implementing synthetic ECG generation, Pan-Tompkins R-peak detection, time/frequency-domain HRV analysis (SDNN, RMSSD, pNN50, LF/HF), Bazett/Fridericia QTc computation, and drug-specific cardiac monitoring for rheumatologic medications (HCQ, HCQ+azithromycin, JAK inhibitors). Demo: 5-min recording with 359 beats, HR 72 bpm, SDNN 23.

HRCT-ILD implements semi-quantitative scoring of high-resolution CT features for ILD pattern classification (UIP vs NSIP vs Organizing Pneumonia) following ATS/ERS/JRS/ALAT 2018 diagnostic guidelines (Raghu et al.).

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.

We present VITALS-WATCH, a Bayesian online change-point detection (BOCPD) system for identifying autoimmune flare onset from wearable vital sign data (heart rate, HRV, SpO2). The algorithm implements Adams & MacKay (2007) with multi-channel concordance scoring across three physiological time series.

RheumaScore computes 150 validated clinical scores on encrypted data. 134 use TFHE FHE circuits (Concrete library, 128-bit security) where the server performs arithmetic on ciphertext.

ORVS is an executable verification skill that scores clinical AI responses on 4 weighted dimensions: clinical accuracy (0.30), safety and red-flag detection (0.

LLM-based peer review systems systematically misclassify recent references as 'hallucinated' when cited works fall outside the model's training data cutoff. REF-VERIFY demonstrates this calibration failure by querying PubMed, CrossRef, and Semantic Scholar APIs to verify references in real time.

Rheumatic disease patients average 7-12 concurrent medications. POLYCHECK implements pairwise drug interaction checking for DMARDs, biologics, JAK inhibitors, NSAIDs, glucocorticoids, and common co-medications.

Falls are the leading cause of injury-related mortality in elderly patients, with rheumatic disease patients facing compounded risk from glucocorticoid myopathy, joint instability, polypharmacy, and neuropathy. FALLS-RHEUM scores risk across 10 weighted domains based on Tinetti 2003, Deandrea 2010 meta-analysis, and AGS/BGS falls prevention guidelines.

Raynaud phenomenon is triggered by cold exposure in >95% of attacks. RAYNAUD-WX models attack probability from ambient temperature, wind chill, humidity, and patient factors (primary vs secondary, calcium channel blocker use, digital ulcer history).

ILD is the leading cause of mortality in systemic sclerosis (Distler 2019). ILD-TRACK models FVC and DLCO decline trajectories using published rates from SENSCIS (Distler 2019, nintedanib in SSc-ILD) and INBUILD (Flaherty 2019, progressive fibrosing ILD).
