Abstract Pathologic immune hyperactivation is emerging as a key feature of critical illness in COVID-19, but the mechanisms involved remain poorly understood. We carried out proteomic profiling plasma from cross-sectional and longitudinal cohorts hospitalized patients with COVID-19 analyzed clinical data our health system database more than 3300 patients. Using machine learning algorithm, we identified prominent signature neutrophil activation, including resistin, lipocalin-2, hepatocyte...

<h3>Importance</h3> Acute kidney injury (AKI) occurs in up to half of patients hospitalized with coronavirus disease 2019 (COVID-19). The longitudinal effects COVID-19–associated AKI on function remain unknown. <h3>Objective</h3> To compare the rate change estimated glomerular filtration (eGFR) after hospital discharge between and without COVID-19 who experienced in-hospital AKI. <h3>Design, Setting, Participants</h3> A retrospective cohort study was conducted at 5 hospitals Connecticut...

Abstract Objective To determine whether electronic health record alerts for acute kidney injury would improve patient outcomes of mortality, dialysis, and progression injury. Design Double blinded, multicenter, parallel, randomized controlled trial. Setting Six hospitals (four teaching two non-teaching) in the Yale New Haven Health System Connecticut Rhode Island, US, ranging from small community to large tertiary care centers. Participants 6030 adult inpatients with injury, as defined by...

The use of guideline-directed medical therapy (GDMT) is underprescribed in patients with heart failure reduced ejection fraction (HFrEF). This study sought to examine whether targeted and tailored electronic health record (EHR) alerts recommending GDMT eligible HFrEF improves use. PROMPT-HF (PRagmatic trial Of Messaging Providers about Treatment Heart Failure) was a pragmatic, EHR-based, cluster-randomized comparative effectiveness trial. A total 100 providers caring for were randomized...

Importance COVID-19 infection is associated with a high incidence of acute kidney injury (AKI). Although rapid function decline has been reported in the first few months after COVID-19−associated AKI (COVID-AKI), longer-term association COVID-AKI remains unknown. Objective To assess long-term outcomes patients who had AKI. Design, Setting, and Participants This was retrospective longitudinal multicenter cohort study conducted large hospital system using electronic health records data on...

Patients hospitalized for acute heart failure (AHF) continue to be discharged on an inadequate number of guideline-directed medical therapies (GDMT) despite evidence that inpatient initiation is beneficial. This study aimed examine whether a tailored electronic health record (EHR) alert increased rates GDMT prescription at discharge in eligible patients AHF.Pragmatic trial messaging providers about treatment (PROMPT-AHF) was pragmatic, multicenter, EHR-based, and randomized clinical trial....

Abstract Poly(ε‐caprolactone) (PCL) with a pendent coumarin group was prepared by solution polycondensation from 7‐(3,5‐dicarboxyphenyl) carbonylmethoxycoumarin dichloride and α, ω‐dihydroxy terminated poly(ε‐caprolactone) molecular weights of 1250, 3000, 10,000 g/mol. These photosensitive polymers underwent rapid reversible photocrosslinking upon exposure to irradiation alternating wavelengths (&gt;280/254 nm) without photoinitiator. The thermal mechanical properties the photocrosslinked...

Background Acute kidney injury (AKI) is an adverse event that carries significant morbidity. Given interventions after AKI occurrence have poor performance, there substantial interest in prediction of prior to its diagnosis. However, integration real-time prognostic modeling into the electronic health record (EHR) has been challenging, as complex models increase risk error and complicate deployment. Our goal this study was create implementable predictive model accurately predict hospitalized...

Background In patients receiving immune checkpoint inhibitor (ICI) therapy, acute kidney injury (AKI) is common, and can occur either from unrelated to ICI use or activation resulting in interstitial nephritis (AIN). this study, we test the hypothesis that occurrence of AIN indicates a favorable treatment response therapy therefore among who develop AKI while on those with will demonstrate greater survival compared others AKI. Methods observational cohort included participants initiated...

Abstract Acute kidney injury is common among hospitalized individuals, particularly those exposed to certain medications, and associated with substantial morbidity mortality. In a pragmatic, open-label, National Institutes of Health-funded, parallel group randomized controlled trial (clinicaltrials.gov NCT02771977), we investigate whether an automated clinical decision support system affects discontinuation rates potentially nephrotoxic medications improves outcomes in patients AKI....
