A dual-therapy sirolimus-eluting and CD34+ antibody-coated Combo Stent (DTS) has been developed to enhance endothelization and capture endothelial progenitor cells; however, vessel responses following DTS implantation remain unclear. Therefore, we evaluated early- and mid-term intravascular characteristics of DTS using intravascular imaging modalities. This multicenter, prospective, observational study enrolled 88 patients (95 lesions) who underwent DTS (43 patients, 48 lesions) or sirolimus-eluting Orsiro stent (SES, 45 patients, 47 lesions) implantation.

Ravulizumab is a second-generation complement component 5 (C5) inhibitor (C5i) approved for the treatment of paroxysmal nocturnal hemoglobinuria (PNH) following positive results from two pivotal trials in patients with PNH originally naive to C5i treatment and eculizumab-experienced patients with PNH. In both trials, after the 26week primary evaluation period, all patients received ravulizumab for up to 6 years. To report ravulizumab treatment outcomes in patients with PNH originally naive to C5i treatment and eculizumab-experienced patients with PNH treated for up to 6 years.

Cardiac allograft vasculopathy (CAV) remains a significant challenge after heart transplantation, necessitating effective surveillance methods. This review centers around the role of coronary computed tomography angiography (CCTA) in CAV surveillance, given its unique capabilities to visualize and quantify CAV in comparison with other imaging modalities, including invasive coronary angiography and intravascular ultrasound. CCTA has shown good diagnostic performance for detecting and monitoring CAV, exemplified by a higher sensitivity and negative predictive value compared with invasive coronary angiography.

This was hypothesized to depend on their prolonged presence in the vasculature, leading to cytotoxicity. Imaging of NETs (histones, neutrophil elastase, extracellular DNA) with intravital microscopy in blood vessels of mouse livers in a pathogen-replicative-free environment (endotoxemia) led to detection of NET proteins attached to the endothelium for months despite the early disappearance of extracellular DNA.

Background: Disseminated intravascular coagulation (DIC) is a common complication in sepsis patients which exacerbates patient outcomes. The prevalence and outcomes of DIC in sepsis is wide-ranging and highly depends on the severity of the disease and diagnostic approaches utilized. Varied diagnostic criteria of DIC have been developed and their performance in diagnosis and prognosis is not consistent.
