Future healthcare systems will rely heavily on clinical decision support (CDSS) to improve the decision-making processes of clinicians. To explore design future CDSS, we developed a research-focused CDSS for management patients in intensive care unit that leverages Internet Things (IoT) devices capable collecting streaming physiologic data from ventilators and other medical devices. We then created machine learning (ML) models could analyze collected determine if ventilator was delivering...

Background Commonly used cardiovascular risk calculators do not provide estimation of stroke, a major postoperative complication with high morbidity and mortality. We developed validated an accurate prediction tool for cardiac complications (myocardial infarction or arrest), mortality after non‐cardiac surgery. Methods Results This retrospective cohort study included 1 165 750 surgical patients over 4‐year period (2007–2010) from the American College Surgeons National Surgical Quality...

We introduce a new paradigm for single-channel target source separation where the sources of interest can be distinguished using non-mutually exclusive concepts (e.g., loudness, gender, language, spatial location, etc). Our proposed heterogeneous framework seamlessly leverage datasets with large distribution shifts and learn cross-domain representations under variety used as conditioning. experiments show that training models conditions facilitates generalization to unseen out-of-domain data...

Recent studies in talking face generation have focused on building a model that can generalize from any source speech to target identity. A number of works already claimed this functionality and added their models will also language. However, we show, using languages different language families, these do not translate well when the training testing are sufficiently different. We reduce scope problem language-robust system seen identities, i.e., identity is same as In work, introduce...

IgA plays a key role in nephropathy (IgAN) by forming immune complexes and depositing the glomeruli, leading to an inflammatory response. However, antigenic targets functional characterization of have been incompletely defined this disease.This study was performed sera from patients who were studied as part prospective, observational IgAN. These (n=22) all had biopsy-proven IgAN within 3 years initiation, complete clinical data, annual urinary inulin clearance for GFRs, at least 5 follow-up....

Individual cytokines have been reported to be associated with the pathogenesis and prognosis of immunoglobulin A (IgA) nephropathy (IgAN). We attempted characterize a broad cytokine matrix in serum patients, investigate its association renal function. Thirty-two were simultaneous-ly measured from IgAN patients (n=22) healthy controls (n=12). Clinical variables including annual inulin based GFR 24-h proteinuria collected on over 5-year period.
