Sleep foundation models now predict over 130 diseases from polysomnography recordings, but their published performance tables do not answer the clinical questions that matter at the point of care: *which* diseases should be screened for a given patient, and *how* should the sleep study be configured to maximize diagnostic yield? We present SleepTriage, a deterministic pipeline that ingests the supplementary performance tables from SleepFM (Thapa et al.

Lupus nephritis affects 40-60% of SLE patients and remains a leading cause of ESRD. NEPHRITIS-LN is an agent-executable clinical decision support skill that computes a 10-domain weighted composite flare risk score incorporating proteinuria, anti-dsDNA titer/trend, complement C3/C4, eGFR trajectory, urinary sediment, immunosuppression adequacy, prior flare history, serological activity, and biopsy chronicity index.

FRAX estimates 10-year fracture probability but provides no guidance on therapeutic selection. We present OSTEO-TX, an open-source expert system that integrates bone turnover biomarkers (serum CTX for resorption, P1NP for formation per IOF/IFCC standards) with FRAX risk stratification and rheumatological modifiers to generate individualized therapeutic recommendations.

We report the identification and resolution of a systemic gap in a Fully Homomorphic Encryption (FHE) clinical score platform serving 167 rheumatology scores. While homomorphic computation on encrypted patient data functioned correctly, all scores returned raw numerical outputs without clinical interpretation — rendering them unusable for clinical decision-making.

We present GOUT-FLARE, an agent-executable clinical decision support skill that predicts the probability of acute gout flare during the first six months of urate-lowering therapy (ULT) initiation. The tool integrates eight evidence-based clinical domains into a weighted composite score (0-100) with Monte Carlo uncertainty estimation (N=10,000), stratifying patients into four risk tiers with guideline-concordant recommendations aligned with ACR 2020 and EULAR 2016 guidelines.

We present ARTHRITIS-BAYESNET, a Directed Acyclic Graph (DAG) Bayesian Network for probabilistic differential diagnosis of five inflammatory arthritides: Rheumatoid Arthritis, Psoriatic Arthritis, Gout, Reactive Arthritis, and SLE with articular predominance. Unlike black-box machine learning classifiers, the network encodes causal clinical reasoning as 20 conditional probability tables derived from ACR/EULAR classification criteria (2010-2023), CASPAR, and expert rheumatologist validation.

We present RheumaScore v4, a production-grade clinical decision support platform that computes 167 validated clinical scores across 14 medical subspecialties using Fully Homomorphic Encryption (FHE). Unlike traditional clinical calculators that process patient data in plaintext, RheumaScore encrypts all clinical inputs in the browser using the Zama Concrete framework, transmits ciphertext to the server, and performs all score computations entirely on encrypted data.

Patients with autoimmune rheumatic diseases frequently require 5-8 concurrent medications spanning DMARDs, biologics, glucocorticoids, NSAIDs, and supportive therapies. POLYCHECK is an executable clinical decision support tool that screens all pairwise medication combinations against a curated, evidence-grounded DDI knowledge base specific to rheumatology.

Vaccination in immunosuppressed patients with rheumatic diseases requires individualized risk-benefit assessment that accounts for medication-specific immunosuppression levels, vaccine type (live vs non-live), disease activity, lymphocyte counts, immunoglobulin levels, and comorbidities. VAX-SAFE implements a composite weighted scoring system (0-100) grounded in ACR 2022, EULAR 2019, and CDC guidelines to classify vaccine-patient pairs as Safe, Conditional, Caution, High Risk, or Contraindicated.

STORM (Stochastic Therapy Optimization for Rheumatology in Mexico) v3.1 is a pharmacogenomic decision-support calculator implementing ancestry-stratified allele frequency interpolation across 18 genes, 39 drugs, and 11 rheumatic diseases.
