Activation of CD1d-restricted invariant NKT (iNKT) cells with the glycolipid α-galactosylceramide (α-GalCer) confers protection against disease in murine models, however, clinical trials in humans have had limited impact. We synthesized a novel thioglycoside analogue of α-GalCer, denoted α-S-GalCer, and tested its efficacy for stimulating human iNKT cells(More)
BACKGROUND Public reporting of procedural outcomes may create disincentives to provide percutaneous coronary intervention (PCI) for critically ill patients. OBJECTIVES This study evaluated the association between public reporting with procedural management and outcomes among patients with acute myocardial infarction (AMI). METHODS Using the Nationwide(More)
BACKGROUND Decisions to proceed with surgical versus percutaneous revascularization for multivessel coronary artery disease are often based on subtle clinical information that may not be captured in contemporary registries. The present study sought to evaluate the association between surgical ineligibility documented in the medical record and long-term(More)
BACKGROUND Early readmission after PCI is an important contributor to healthcare expenditures and a target for performance measurement. The extent to which 30-day readmissions after PCI are preventable is unknown yet essential to minimizing their occurrence. METHODS AND RESULTS PCI patients readmitted to hospital at which PCI was performed within 30 days(More)
BACKGROUND Rehospitalization within 30 days after an admission for percutaneous coronary intervention (PCI) is common, costly, and a future target for Medicare penalties. Causes of readmission after PCI are largely unknown. METHODS AND RESULTS To illuminate the causes of PCI readmissions, patients with PCI readmitted within 30 days of discharge between(More)
OBJECTIVES This study sought to quantify depression rates in patients referred for percutaneous coronary intervention (PCI) for chronic total occlusion (CTO), assess its relationship to baseline angina symptoms, and compare angina improvement after CTO-PCI between depressed and non-depressed patients. BACKGROUND Depression is common among patients with(More)
BACKGROUND Early readmission after percutaneous coronary intervention is an important quality metric, but prediction models from registry data have only moderate discrimination. We aimed to improve ability to predict 30-day readmission after percutaneous coronary intervention from a previously validated registry-based model. METHODS AND RESULTS We matched(More)
BACKGROUND Percutaneous coronary intervention is the most commonly performed revascularization modality for chronic stable angina, but does not improve survival or reduce major adverse cardiovascular event. Percutaneous coronary intervention in this population is performed primarily for symptomatic benefit; therefore, symptom reduction is an important(More)
Readmission after hospitalization for acute myocardial infarction (AMI) significantly contributes to preventable morbidity and health-care costs. Outcomes after AMI vary by sex but the relationship of sex to readmissions warrants further exploration. Using the 2013 Nationwide Readmissions Database, we identified patients with a principal discharge diagnosis(More)
We thank our colleagues for reading and commenting on our recently published article. Our results suggested that documentation of surgical ineligibility was common (22%) among patients undergoing percutaneous revascularization for multivessel coronary artery disease. Furthermore, documentation of surgical ineligibility was associated with an increased risk(More)
