CD91-mediated reprogramming of DCs by immunogenic heat shock proteins requires the kinases AXL and Fgr.

Immune responses to tumors, comprising adaptive T cells and innate NK cells, arise very early in tumorigeneses and prior to detection of palpable tumors or before tissue pathology is evident. Yet, how nascent tumors evoke dendritic cell maturation and the resulting cytokine responses that are necessary for these effector anti-tumor immune responses is unknown. We have previously shown that CD91 expression on dendritic cells is important for immune surveillance, specifically for generating T cell and NK cell responses to nascent tumors.

Health outcomes in Deaf signing populations: A systematic review.

Objectives: (i) To identify peer reviewed publications reporting the mental and/or physical health outcomes of Deaf adults who are sign language users and to synthesise evidence; (ii) If data available, to analyse how the health of the adult Deaf population compares to that of the general population; (iii) to evaluate the quality of evidence in the identified publications; (iv) to identify limitations of the current evidence base and suggest directions for future research.

Design: Systematic review.

Data Sources: Medline, Embase, PsychINFO, and Web of Science.

Residual or recurrent mitral regurgitation predicts mortality following transcatheter edge-to-edge mitral valve repair.

Objective: Although regurgitant mitral valves can be repaired through surgical or transcatheter approaches, contemporary comparative outcomes are limited with the impact of residual and recurrent mitral regurgitation (MR) on clinical outcomes being poorly defined. We hypothesized that moderate (2+) or greater residual or recurrent (RR) MR-regardless of type of repair-predicts worse clinical outcomes.

Methods: Our institutional experience of 660 consecutive patients undergoing mitral valve repair (2015-2021) consisting of 393 surgical mitral valve repair (SMVr) and 267 transcatheter edge-to-edge mitral valve repair (TEER) was studied.

Transcatheter mitral valve in ring, hazards of long anterior mitral leaflet and 3-dimensional rings.

Objectives: The purpose of this study was to define anterior mitral leaflet (AML) length and mitral ring characteristics associated with LVOT obstruction and PVL following MViR.

Background: Transcatheter Mitral Valve in Ring (MViR) procedural complications including parvalvular leak (PVL) and left ventricular outflow tract (LVOT) obstruction are frequent.

Methods: Clinical records, computer tomographic scans (CTs) and echocardiograms of consecutive MViR patients were retrospectively reviewed for anterior mitral leaflet length, CT-simulated neoLVOT, and aortomitral angle among patients with and without MViR-induced LVOT obstruction.

Transcatheter Aortic Valve-in-Valve Replacement for Degenerated Stentless Bioprosthetic Aortic Valves: Results of a Multicenter Retrospective Analysis.

Objectives: The purpose of this study was to evaluate the safety and efficacy of valve-in-valve (ViV) transcatheter aortic valve replacement (TAVR) for stentless bioprosthetic aortic valves (SBAVs) and to identify predictors of adverse events.

Background: ViV TAVR in SBAVs is associated with unique technical challenges and risks.

Methods: Clinical records and computer tomographic scans were retrospectively reviewed for procedural complications, predictors of coronary obstruction, mortality, and echocardiographic results.

Exertional dyspnea as a symptom of infrarenal aortic occlusive disease.

Advanced atherosclerosis of the aorta can cause severe ischemia in the kidneys, refractory hypertension, and claudication. However, no previous reports have clearly associated infrarenal aortic stenosis with shortness of breath. A 77-year-old woman with hypertension and hyperlipidemia presented with exertional dyspnea.

Baseline subclinical atherosclerosis burden and distribution are associated with frequency and mode of future coronary revascularization: multi-ethnic study of atherosclerosis.

Objectives: The aim of this study was to evaluate the impact of coronary artery calcium (CAC) burden and regional distribution on the need for and type of future coronary revascularization-percutaneous versus surgical (coronary artery bypass graft [CABG])-among asymptomatic subjects.

Background: The need for coronary revascularization and the chosen mode of revascularization are thought to be functions of disease burden and anatomic distribution. The association between the baseline burden and regional distribution of CAC and the risk and type of future coronary revascularization remains unknown.

Myocardial ischemia and ventricular tachycardia on continuous electrocardiographic monitoring and risk of cardiovascular outcomes after non-ST-segment elevation acute coronary syndrome (from the MERLIN-TIMI 36 Trial).

Among patients with non-ST-segment elevation acute coronary syndromes, recurrent ischemia and ventricular arrhythmias detected on continuous electrocardiographic monitoring remain common events that are associated with worse outcomes. The relative clinical significance of both events together is not well described. We determined the risk associated with ischemia (≥1 mm ST depression lasting ≥1 minutes) and ventricular tachycardia (VT) (≥4 beats) detected on 7-day continuous electrocardiographic monitoring in 6,355 patients with non-ST-segment elevation acute coronary syndromes from the Metabolic Efficiency with Ranolazine for Less Ischemia in Non-ST-elevation Acute Coronary Syndrome-Thrombolysis In Myocardial Infarction (MERLIN-TIMI) 36 trial.

Extent of ST-segment resolution after fibrinolysis adds improved risk stratification to clinical risk score for ST-segment elevation myocardial infarction.

Background: The TIMI risk score (TRS) for ST-segment elevation myocardial infarction (STEMI) is a convenient validated clinical risk score for predicting mortality. Although not part of the risk score, ST-segment resolution (STRes) may provide a simple method of risk stratification based on the response to reperfusion. We sought to determine whether STRes provides incremental risk stratification to the TIMI risk score.

A 32-year experience with surgical repair of sinus of valsalva aneurysms.

Introduction: Sinus of Valsalva (SoV) aneurysms are rare (0.15% to 1.5% CPB cases) and five times more frequent in Asians.
