Aims: Atrial fibrillation (AF) is the most common sustained arrhythmia. Previous evidence in animal models suggests that the gap junction (GJ) adjacent nanodomain - perinexus - is a site capable of independent intercellular communication via ephaptic transmission. Perinexal expansion is associated with slowed conduction and increased ventricular arrhythmias in animal models, but has not been studied in human tissue. The purpose of this study was to characterize the perinexus in humans and determine if perinexal expansion associates with AF...

BACKGROUND: We examined the association of pre-operative cell count abnormalities, which have been shown to be associated with outcomes in adult cardiac patients, with morbidity and mortality following surgery for congenital heart disease (CHD) in children. METHODS: We performed a retrospective cohort study on 4865 children undergoing cardiac surgery from 2004- 2014. Our exposures of interest were presence of pre-operative lymphopenia (lymphocyte count ≤ 3000 cells/μL), thrombocytopenia (platelet count < 150 x103 / μL), and neutrophilia (neutrophil count ≥ 7000 cells/ μL)...

The current study examined the contribution of central and peripheral adaptations to changes in maximal oxygen uptake (VO<sub>2</sub>max) following sprint interval training (SIT). Twenty-three males completed four weekly SIT sessions (8 x 20 second cycling bouts at ~170% of work rate at VO<sub>2</sub>max, 10 second recovery) for four weeks. Following completion of training, the relationship between changes in VO<sub>2</sub>max and changes in central (cardiac output) and peripheral (a-vO<sub>2</sub>diff, muscle capillary density, oxidative capacity, fibre-type distribution) adaptations was determined in all participants using correlation analysis...

Two neonates with congenital heart disease, one and thirty-one days old respectively, suffered inadvertent arterial injury from cardiac catheterization. Both insults resulted in unrecognized avulsion of the external iliac artery from its origin. The patients quickly decompensated, with their right lower extremities becoming critically ischemic. In both cases, segments of reversed greater saphenous vein were used as interposition grafts from the common iliac artery to the common femoral artery. Reperfusion of the right foot was immediate for the one-day-old...

Individuals with type 2 diabetes have a three-to-five-fold increased risk of developing heart failure. Diabetic cardiomyopathy is typified by left ventricular (LV) concentric remodelling, which is a recognised predictor of adverse cardiovascular events. Although the mechanisms underlying LV remodelling in type 2 diabetes are unclear, progressive aortic stiffening may be a key determinant. The aim of this study was to assess the relationship between aortic stiffness and LV geometry in younger adults with type 2 diabetes, using multiparametric cardiovascular magnetic resonance imaging...

Stroke has multiple etiologies, but the underlying genes and pathways are largely unknown. We conducted a multiancestry genome-wide-association meta-analysis in 521,612 individuals (67,162 cases and 454,450 controls) and discovered 22 new stroke risk loci, bringing the total to 32. We further found shared genetic variation with related vascular traits, including blood pressure, cardiac traits, and venous thromboembolism, at individual loci (n = 18), and using genetic risk scores and linkage-disequilibrium-score regression...

Myocardin is a transcriptional co-activator required for cardiovascular development, but also promotes cardiomyocyte survival through an unclear molecular mechanism. Mitochondrial permeability transition is implicated in necrosis, while pore closure is required for mitochondrial maturation during cardiac development. We show that loss of myocardin function leads to subendocardial necrosis at E9.5, concurrent with elevated expression of the death gene Nix. Mechanistically, we demonstrate that myocardin knockdown reduces microRNA-133a levels to allow Nix accumulation, leading to mitochondrial permeability transition, reduced mitochondrial respiration, and necrosis...

Extracorporeal membrane oxygenation (ECMO) has been used increasingly for both respiratory and cardiac failure in adult patients. Indications for ECMO use in cardiac failure include severe refractory cardiogenic shock, refractory ventricular arrhythmia, active cardiopulmonary resuscitation for cardiac arrest, and acute or decompensated right heart failure. Evidence is emerging to guide the use of this therapy for some of these indications, but there remains a need for additional evidence to guide best practices...

Oritavancin is a lipoglycopeptide with bactericidal activity against Gram-positive organisms. Its rapid concentration-dependent bactericidal activity and long elimination half-life allow single-dose treatment of acute bacterial skin and skin structure infections (ABSSSI). SOLO I and SOLO II were randomized, double-blind studies evaluating the efficacy and safety of a single 1,200-mg intravenous (i.v.) dose of oritavancin versus twice-daily i.v. vancomycin for 7 to 10 days in ABSSSI patients. Safety data from both studies were pooled for safety analysis...

Truncating mutations in the sarcomere protein titin cause dilated cardiomyopathy due to sarcomere insufficiency. However, it remains mechanistically unclear how these mutations decrease sarcomere content in cardiomyocytes. Utilizing human induced pluripotent stem cell-derived cardiomyocytes, CRISPR/Cas9, and live microscopy, we characterize the fundamental mechanisms of human cardiac sarcomere formation. We observe that sarcomerogenesis initiates at protocostameres, sites of cell-extracellular matrix adhesion, where nucleation and centripetal assembly of α-actinin-2-containing fibers provide a template for the fusion of Z-disk precursors, Z bodies, and subsequent striation...

BACKGROUND: Efforts to safely reduce length of stay for emergency department patients with symptoms suggestive of acute coronary syndrome (ACS) have had mixed success. Few system-wide efforts affecting multiple hospital emergency departments have ever been evaluated. We evaluated the effectiveness of a nationwide implementation of clinical pathways for potential ACS in disparate hospitals. METHODS: This was a multicenter pragmatic stepped-wedge before-and-after trial in 7 New Zealand acute care hospitals with 31 332 patients investigated for suspected ACS with serial troponin measurements...
