- Longitudinal Tracking of Valve Regurgitation from Peripheral Photoplethysmography Using a 1D Hemodynamic Surrogate: a Joint MCMC-Kalman Framework
Aortic (AR) and mitral (MR) regurgitation are progressive valvulopathies whose management depends on tracking severity over months to years, currently via infrequent clinic-bound echocardiography. We investigated whether peripheral photoplethysmography (PPG) can track AR and MR longitudinally despite unknown day-to-day hemodynamic variation. A one-dimensional Navier--Stokes arterial model from aortic root to pedal digital artery, with parametric AR and MR at the inlet, generated distal waveforms from which we extracted eleven morphological features. Univariate sensitivity, Cramer--Rao bound, and feature-ablation analyses quantified theoretical observability under realistic noise and physiological variability. A neural surrogate of the 1D model was embedded in a joint Markov Chain Monte Carlo (MCMC)--Kalman scheme that tracked regurgitant fraction monthly while marginalizing over unknown systemic parameters. Across 240 synthetic patients spanning stable and high-risk AR and MR, with and
- A Clinical Prediction Model for Sudden Cardiac Arrest Presenting as Pulseless Electrical Activity
Background: The incidence of sudden cardiac arrest (SCA) manifesting as pulseless electrical activity (PEA) has increased, and survival remains extremely low. Methods for early identification and management of high-risk individuals are needed, but no clinical risk scores currently exist to predict PEA-SCA. Our objective was to develop and validate a clinical prediction model for PEA-SCA. Methods: From an ongoing prospective, population-based study of SCA in Portland, Oregon (catchment pop. ?1 M, 2002-2020), we identified PEA-SCA adults. Lifetime clinical records were compared with those of a control group with >50% prevalence of significant coronary disease. Prediction models were constructed using backwards stepwise logistic regression in a training dataset (67%) and evaluated in a validation dataset (33%). Model discrimination was assessed using receiver operating characteristic curves (C statistic). External validation was performed in a geographically distinct population in Ventura
- Continuous monitoring of endotracheal tube obstructions using naturally occurring pressure and flow oscillations
The endotracheal tube resistance dominates the total airway resistance in most intubated patients. Mucus deposition and biofilm formation can rapidly increase tube resistance and thereby contribute to serious ventilatory impairments, including dynamic hyperinflation, intrinsic PEEP build-up, added work of breathing, and patient-ventilator asynchrony. During controlled mechanical ventilation, an increased tube resistance can be inferred from the difference between peak and plateau pressure, but this approach fails during pressure-supported spontaneous breathing. Here, we present a method that estimates the linear and nonlinear components of tube resistance from naturally occurring airway pressure and flow fluctuations at the airway opening, without a tracheal pressure sensor and without applying mandatory forced oscillations. This is achieved by solving the equation of motion using band-pass filtered airway pressure and flow signals. Band-pass filtering isolates the relevant resistive a
- Unmeasured but Not Unbiased: The Missingness Demographic Leakage Audit (MDLA) for Calibration-Aware Fairness Evaluation in Critical Care Mortality Prediction
Objective Clinical prediction models trained on electronic health records are routinely evaluated for fairness on observed feature values, but the informativeness of which measurements are absent remains unaudited. We developed the Missingness Demographic Leakage Audit (MDLA), a reproducible four-step informatics framework that tests whether patterns of clinical measurement absence function as latent demographic proxies - constituting a bias pathway invisible to standard fairness audits. Materials and Methods We applied MDLA across development (MIMIC-IV v2.2; n=50,827; mortality 10.2%) and external validation (eICU-CRD v2.0; n=137,773; mortality 9.5%) cohorts following TRIPOD+AI standards. XGBoost, random forest, and logistic regression were trained on 43 clinical features and 44 binary missingness indicators. MDLA quantified demographic predictability from missingness alone, tested feature-level associations with Bonferroni correction, and verified model reliance via ablation. A calib

- Systemic ELOVL6 activity predicts survival and represents a modifiable target of amyotrophic lateral sclerosis
Amyotrophic lateral sclerosis (ALS) is characterized by profound metabolic reprogramming, yet the lack of biomarkers for specific druggable targets remains a major hurdle for precision medicine. We hypothesized that peripheral lipid biosynthetic signatures could serve as both prognostic indicators and a roadmap for identifying novel disease-modifying targets. We assessed serum fatty acid (FA) metabolic pathways in two independent longitudinal cohorts (n = 37 and n = 38) using high-dimensional CoxBoost modeling. Primary outcomes were survival and functional staging milestones, including non-invasive ventilation and gastrostomy. The biological relevance of the identified candidate was further assessed through correlation with plasma neurofilament light-chain (NfL) levels. Causality and therapeutic potential were validated in Drosophila melanogaster models of TDP-43 proteinopathy via genetic ablation and pharmacological inhibition. Our multi-parametric model, comprising two clinical varia
