Prostaglandin E1 administration post liver transplantation and renal outcomes: A retrospective single center experience.

Background: Prostaglandin E1 (PGE1), or alprostadil, is a potent vasodilator that improves hepatic blood flow and reduces ischemia-reperfusion injury post-liver transplantation (LT). However, the benefits of PGE1 on renal function after LT have not yet been well described.

Aim: To assess the impact of PGE1 administration on renal function in patients who underwent liver or liver-kidney transplant.

Time from admission to randomization and the effect of empagliflozin in acute heart failure: A post-hoc analysis from EMPULSE.

Aims: Patients hospitalized for acute heart failure (HF) could be enrolled in EMPULSE (NCT04157751) upon haemodynamic stabilization and between 24 h and 5 days after hospital admission. The timing of treatment initiation may influence the efficacy and safety of drugs such as empagliflozin. The aim of this study was to evaluate patient characteristics, clinical events, and treatment effects according to time from admission to randomization.

Nonobstructive epicardial coronary artery disease: an evolving concept in need of diagnostic and therapeutic guidance.

For decades, we have been treating patients presenting with angina and concerning electrocardiographic changes indicative of ischemia or injury, in whom no culprit epicardial coronary stenosis was found during diagnostic coronary angiography. Unfortunately, the clinical outcomes of these patients were not better than those with recognized obstructive coronary disease. Improvements in technology have allowed us to better characterize these patients.

Effect of PCI on Health Status in Ischemic Left Ventricular Dysfunction: Insights From REVIVED-BCIS2.

Background: In the REVIVED-BCIS2 (Revascularization for Ischemic Ventricular Dysfunction) trial, percutaneous coronary intervention (PCI) did not reduce the incidence of death or hospitalization for heart failure (HHF).

Objectives: This prespecified secondary analysis investigated the effect of PCI on health status measured with the Kansas City Cardiomyopathy Questionnaire (KCCQ) combined with the primary outcome in a win ratio.

Methods: Participants with severe ischemic left ventricular dysfunction were randomized to either PCI in addition to optimal medical therapy (OMT) (PCI) or OMT alone (OMT).

Multidisciplinary Approach to Deciphering Etoposide Infusion Reactions and Potential Role of Polyethersulfone Filter Membranes.

Purpose: Etoposide, a topoisomerase II inhibitor used clinically to treat cancer, has been associated with severe anaphylactic infusion related adverse drug reactions (ADRs). In a previous study we identified a hydrophilic polyethersulfone filter as a possible cause of increased rates of pediatric etoposide infusion reactions. In this multidisciplinary follow-up analytical study, we aimed to assess the chemical structure of etoposide after passing through the same hydrophilic polyethersulfone filter.

Mineralocorticoid receptor antagonist use and the effects of empagliflozin on clinical outcomes in patients admitted for acute heart failure: Findings from EMPULSE.

Aims: In patients hospitalized for acute heart failure (AHF) empagliflozin produced greater clinical benefit than placebo. Many patients with AHF are treated with mineralocorticoid receptor antagonists (MRAs). The interplay between empagliflozin and MRAs in AHF is yet to be explored.

Accurate and efficient rapid acquisition early post-injection stress-first CZT SPECT myocardial perfusion imaging with tetrofosmin and attenuation correction.

Introduction: Myocardial perfusion imaging (MPI) protocols have not changed significantly despite advances in instrumentation and software. We compared an early post-injection, stress-first SPECT protocol to standard delayed imaging.

Methods: 95 patients referred for SPECT MPI were imaged upright and supine on a Spectrum Dynamics D-SPECT CZT system with CT attenuation correction.

Impact of Complete Revascularization in the ISCHEMIA Trial.

Background: Anatomic complete revascularization (ACR) and functional complete revascularization (FCR) have been associated with reduced death and myocardial infarction (MI) in some prior studies. The impact of complete revascularization (CR) in patients undergoing an invasive (INV) compared with a conservative (CON) management strategy has not been reported.

Objectives: Among patients with chronic coronary disease without prior coronary artery bypass grafting randomized to INV vs CON management in the ISCHEMIA (International Study of Comparative Health Effectiveness with Medical and Invasive Approaches) trial, we examined the following: 1) the outcomes of ACR and FCR compared with incomplete revascularization; and 2) the potential impact of achieving CR in all INV patients compared with CON management.

Outcomes of Bioprosthetic Valve Fracture in Patients Undergoing Valve-in-Valve TAVR.

Background: Valve-in-valve (VIV) transcatheter aortic valve replacement (TAVR) is increasingly used to treat degenerated surgical bioprostheses. Bioprosthetic valve fracture (BVF) has been shown to improve hemodynamic status in VIV TAVR in case series. However, the safety and efficacy of BVF are unknown.

Correlation of Relative Value Units With Surgical Complexity and Physician Workload: A Contemporary Nationwide Analysis of Orthopaedic Procedures.

Introduction: Although previous studies have demonstrated inconsistencies between surgeon work and reimbursement, no previous study has calculated expected relative value units (RVUs) based on procedure-specific variables. Our study aimed to evaluate how measures of physician workload and surgical complexity correlate with the work RVUs (wRVUs) assigned to orthopaedic procedures and compare our predicted wRVUs with actual wRVUs.

Methods: The National Surgical Quality Improvement Program was used to identify orthopaedic surgeries with the highest procedural volume in 2019.

Sex difference in the association between type of bystander CPR and clinical outcomes in patients with out of hospital cardiac arrest.

Background: A recent study suggested that women with out-of-hospital cardiac arrest have a smaller survival benefit with bystander cardiopulmonary resuscitation than men. We evaluated whether this weaker association between bystander cardiopulmonary resuscitation and survival in women is related to dispatcher-assisted vs unassisted bystander cardiopulmonary resuscitation.

Methods: In a national registry in the Republic of Korea, we identified adult patients with out-of-hospital cardiac arrest during 2013-2018.

Survival After Invasive or Conservative Management of Stable Coronary Disease.

Background: The ISCHEMIA trial (International Study of Comparative Health Effectiveness With Medical and Invasive Approaches) compared an initial invasive versus an initial conservative management strategy for patients with chronic coronary disease and moderate or severe ischemia, with no major difference in most outcomes during a median of 3.2 years. Extended follow-up for mortality is ongoing.

Impact of Patient-Reported Outcome Measurement in Heart Failure Clinic on Clinician Health Status Assessment and Patient Experience: A Substudy of the PRO-HF Trial.

Background: Clinicians typically estimate heart failure health status using the New York Heart Association Class, which is often discordant with patient-reported health status. It is unknown whether collecting patient-reported health status improves the accuracy of clinician assessments.

Methods: The PRO-HF trial (Patient-Reported Outcomes in Heart Failure Clinic) is a randomized, nonblinded trial evaluating routine Kansas City Cardiomyopathy Questionnaire-12 (KCCQ-12) collection in heart failure clinic.

Impact of empagliflozin on decongestion in acute heart failure: the EMPULSE trial.

Aims: Effective and safe decongestion remains a major goal for optimal management of patients with acute heart failure (AHF). The effects of the sodium-glucose cotransporter 2 inhibitor empagliflozin on decongestion-related endpoints in the EMPULSE trial (NCT0415775) were evaluated.

Methods And Results: A total of 530 patients hospitalized for AHF were randomized 1:1 to either empagliflozin 10 mg once daily or placebo for 90 days.

Long-Term Outcomes for Out-of-Hospital Cardiac Arrest in Elderly Patients: An Analysis of Cardiac Arrest Registry to Enhance Survival Data Linked to Medicare Files.

Background: Most studies on out-of-hospital cardiac arrest have primarily focused on in-hospital or short-term survival. Little is known about long-term outcomes and resource use among survivors of out-of-hospital cardiac arrest.

Methods: In this observationsl study, we describe overall long-term outcomes for patients from the national Cardiac Arrest Registry to Enhance Survival linked to Medicare files to create the Cardiac Arrest Registry to Enhance Survival: Mortality, Events, and Costs for Cardiac Arrest survivors dataset.

Sex differences in the association between bystander CPR and survival for Out-of-Hospital cardiac arrest.

Background: Prior studies have identified socio-cultural barriers in laypersons performing high-quality cardiopulmonary resuscitation (CPR) in women. Whether the effect of layperson bystander CPR on survival from out-of-hospital cardiac arrest (OHCA) differs by patients' sex is unknown.

Methods: Using data during 2013-2020 from an OHCA registry in the U.

Race and ethnicity data in the cardiac arrest registry to enhance survival: Insights from medicare self-reported data.

Background: For out-of-hospital cardiac arrest (OHCA), assignment of race/ethnicity data can be challenging. Validation of race/ethnicity in registry data with patients' self-reported race/ethnicity would provide insights regarding misclassification.

Methods: Using recently linked 2013-2019 Cardiac Arrest Registry to Enhance Survival (CARES) data with Medicare files, we examined the concordance of race/ethnicity in CARES with self-reported race/ethnicity in Medicare.
