Background— All treatments of acute myocardial infarction are aimed at rapid revascularization the occluded vessel; however, no clinical strategies currently available to protect heart from ischemia/reperfusion injury after restitution blood flow. We hypothesized that some cholesterol transport–independent biological properties high-density lipoprotein (HDL) implied in atheroprotection may also be beneficial settings reperfusion injury. Methods and Results— In an vivo mouse model...

ABSTRACT Background SARS-CoV-2 antigen rapid diagnostic tests (Ag-RDTs) are increasingly being integrated in testing strategies around the world. Studies of Ag-RDTs have shown variable performance. In this systematic review and meta-analysis, we assessed clinical accuracy (sensitivity specificity) commercially available Ag-RDTs. Methods Results We registered on PROSPERO (Registration number: CRD42020225140). systematically searched multiple databases (PubMed, Web Science Core Collection,...

Myocardial infarction after major surgery is frequent, drives outcome, and consumes health resources. Specific prediction detection of perioperative myocardial an unmet clinical need. With the widespread use high-sensitive cardiac troponin T assays, positive tests become but their diagnostic or prognostic impact arguable. We, therefore, studied association routinely determined pre- postoperative with occurrence adverse events.This study was a prospective non-interventional trial.This...

<h3>Importance</h3> Morbidity is still high in pancreatic surgery, driven mainly by gastrointestinal complications such as fistula. Perioperative thoracic epidural analgesia (EDA) and patient-controlled intravenous (PCIA) are frequently used for pain control after surgery. Evidence from a post hoc analysis suggests that PCIA associated with fewer complications. <h3>Objective</h3> To determine whether postoperative decreases the occurrence of surgery compared EDA. <h3>Design, Setting,...

Current clinical guidelines recommend antifibrinolytic treatment for liver transplantation to reduce blood loss and transfusion utilization. However, the relevance of fibrinolysis during is questionable, a benefit tranexamic acid (TXA) in this context not supported by sufficient evidence, adverse effects are also conceivable. Therefore, we tested hypothesis that use TXA associated with reduced loss.

The main risk factor for developing transplant vasculopathy (TV) after solid organ transplantation is de-novo production of donor-specific antibodies (DSAs) binding to endothelial cells (ECs) within the graft’s vasculature. Diverse leukocyte populations recruited into vessel wall via activated ECs contribute vascular inflammation. Subsequent smooth muscle cell proliferation results in intima hyperplasia, pathophysiological correlate TV. We demonstrated that incubating aortic EC with...

Thrombomodulin (TM), via its lectin-like domain (LLD), exhibits anti-inflammatory properties partly by sequestering the pro-inflammatory cytokine, high-mobility group box 1 (HMGB1). Since myocardial damage after ischaemia and reperfusion is mediated inflammation, we evaluated cardioprotective effects of LLD TM. Using an in vivo mouse model transient vitro models cardiomyocyte hypoxia, assessed ability to suppress HMGB1-mediated activation receptors, receptor for advanced glycation...

Myocardial infarction (MI) results in acute impairment of left ventricular (LV) function through the initial development cardiomyocyte death and subsequent progression LV remodelling. The expression syndecan-4 (Sdc4), a transmembrane proteoglycan, is up-regulated after MI, but its heart remains unknown. Here, we characterize effects Sdc4 deficiency murine myocardial ischaemia permanent infarction. Targeted deletion (Sdc4–/–) leads to increased damage ischaemic–reperfusion injury due enhanced...

Vascular calcification is a severe consequence of several pathological processes with lack effective therapy. Recent studies suggest that circulating and resident mesenchymal stem cells (MSC) contribute to the osteogenic program vascular calcification. Molecular mechanisms underlying MSC potential differentiation remain, however, sparsely explored. We investigated role for complement receptor C5aR in these processes. found expression was upregulated upon human osteoblasts. inhibition by...
