INTRODUCTION: Alteplase and tenecteplase are two widely used thrombolytic agents and are both approved for the treatment of acute myocardial infarction. These two molecules have increased fibrin specificity compared with older thrombolytics but distinct pharmacokinetic properties and may differ in terms of risks and benefits. We decided to review the available evidence comparing the safety and efficacy of these two molecules in acute coronary syndrome (ACS) or pulmonary embolism (PE)...

BACKGROUND AND PURPOSE: In patients who present with acute ischemic stroke while on treatment with non-vitamin K antagonist oral anticoagulants (NOACs), coagulation testing is necessary to confirm the eligibility for thrombolytic therapy. We evaluated the current use of coagulation testing in routine clinical practice in patients who were on NOAC treatment at the time of acute ischemic stroke. METHODS: Prospective multicenter observational RASUNOA registry (Registry of Acute Stroke Under New Oral Anticoagulants; February 2012-2015)...

OBJECTIVE: Despite being the standard of care, thrombolytic therapy with tissue plasminogen activator (t-PA) is currently administered to only 5% of acute ischemic stroke (AIS) patients in the United States. Published scientific information regarding both the use of t-PA for AIS in Hispanic patients and its impact on short-term mortality is scarce. The objectives of this study are to investigate, among Puerto Rican patients hospitalized with AIS, the rate of t-PA administration, and the risk of in-hospital mortality in patients who received t-PA vs...

Traversing proton beam-irradiated, mid/high-Z nanoparticles produce site-specific enhancement of X-ray photon-electron emission via the Coulomb nanoradiator (CNR) effect, resulting in a nano- to micro-scale therapeutic effect at the nanoparticle-uptake target site. Here, we demonstrate the uptake of iron oxide nanoparticles (IONs) and nanoradiator-mediated, site-specific thrombolysis without damaging the vascular endothelium in an arterial thrombosis mouse model. The enhancement of low-energy electron (LEE) emission and reactive oxygen species (ROS) production from traversing proton beam-irradiated IONs was examined...

BACKGROUND Graft thrombosis is the main cause of early graft loss after transplantation. In Japan, pancreases available for transplantation are frequently from marginal donors due to diverse backgrounds in the population. However, marginal tissues increase the risk of early thrombosis in the graft. CASE REPORT Here, we describe a 41-year-old woman with type 1 diabetes mellitus who underwent a simultaneous pancreas-kidney transplantation. The pancreas was retrieved from a 34-year-old man who had experienced severe hemodynamic instability...

Portal vein thrombosis (PVT) is a rare complication of liver transplantation which can lead to graft failure and patient death. Treatment can be difficult, especially in cases of PVT from the intrahepatic portal vein to the proximal jejunal veins. A 55-year-old woman had undergone living-donor liver transplantation with splenectomy for end-stage liver cirrhosis due to hepatitis C with hepatocellular carcinoma. Ten months after transplantation, massive ascites and slight abdominal pain developed, and computed tomography revealed a PVT between the intrahepatic portal vein and the superior mesenteric vein...

Acute myocardial infarction (AMI) is uncommon in the acute phase of acute ischemic stroke (AIS) and occurs in approximately 1% of the population. Here, we report a paradoxical case of AMI during tissue plasminogen activator (t-PA) infusion for AIS. We review and analyze the previously reported cases. We found that only patients with AMI which occurred after thrombolytic therapy for AIS who received an adequate combination of anticoagulation plus percutaneous coronary intervention survived their events. Several mechanisms have been proposed for the development of AMI after thrombolytic therapy...

Telestroke services have been shown to increase stroke therapy access in rural areas. The implementation of advanced CT imaging for patient assessment may improve patient selection and detection of stroke mimics in conjunction with telestroke. We implemented a telestroke service supported by multimodal CT imaging in a rural hospital in Australia. Over 21months we conducted an evaluation of service activation, thrombolysis rates and use of multimodal imaging to assess the feasibility of the service. Rates of symptomatic intracranial haemorrhage and 90-day modified Rankin Score were used as safety outcomes...

BACKGROUND: Age- and sex-specific differences exist in the treatment and outcome of ST-elevation myocardial infarction (STEMI). We sought to describe age- and sex-matched contemporary trends of in-hospital management and outcome of patients with STEMI. METHODS AND RESULTS: We analyzed data from 5 Italian nationwide prospective registries, conducted between 2001 and 2014, including consecutive patients with STEMI. All the analyses were age- and sex-matched, considering 4 age classes: <55, 55 to 64, 65 to 74, and ≥75 years...

BACKGROUND: The lack of fluid-attenuated inversion-recovery (FLAIR) hyperintensity in areas of diffusion-weighted imaging (DWI) high signal, or DWI-FLAIR mismatch, is a potential imaging biomarker for timing of stroke onset. We aimed to determine the effects of DWI infarct lesion volume on DWI-FLAIR mismatch and its accuracy for identification of strokes within intravenous (IV) the thrombolytic therapy window. METHODS: Acute ischemic stroke patients with magnetic resonance imaging scan within 12 hours of witnessed stroke were included...

Recent data have shown that normobaric oxygen (NBO) increases the catalytic and thrombolytic efficiency of recombinant tissue plasminogen activator (rtPA) in vitro, and is as efficient as rtPA at restoring cerebral blood flow in rats subjected to thromboembolic brain ischemia. Therefore, in the present study, we studied the effects of hyperbaric oxygen (HBO) (i) on rtPA-induced thrombolysis in vitro and (ii) in rats subjected to thromboembolic middle cerebral artery occlusion-induced brain ischemia. HBO increases rtPA-induced thrombolysis in vitro to a greater extent than NBO; in addition, HBO treatment of 5-minute duration, but not of 25-minute duration, reduces brain damage and edema in vivo...

The use of ultrasound waves in conjunction with local thrombolysis may accelerate clot resolution and serve as an important therapeutic adjunct in the treatment of venous occlusive disease. Our goal was to provide a larger sample population over a 5-year period to evaluate our experience with the EkoSonic endovascular system (EKOS, EKOS Corporation, Bothell, WA). We suspected that ultrasound-accelerated thrombolysis (UAT) using EKOS would provide excellent thrombolysis and midterm patency rates with minimal thrombolytic complications...

In this review we focus on shear targeted drug delivery as a novel strategy to selectively deliver drugs to sites of vascular obstruction. We review the physics of stenotic (abnormally narrowed) blood vessels, while focusing mainly on the hemodynamics and transport phenomena at these sites. We then discuss how the local abnormal levels of shear stress, which can mechanically activate platelets, can be leveraged for localized drug delivery. We describe the development of Shear Activated Nano-particle Aggregates (SA-NPAs) that are designed to release and localize their nanoparticle drug carriers at sites of vascular stenosis...

BACKGROUND: Acute stroke is a time-sensitive condition in which rapid diagnosis must be made in order for thrombolytic treatment to be administered. A certain proportion of patients who receive thrombolysis will be found on further evaluation to have a diagnosis other than stroke, so-called "stroke mimics." Little is known about the role of language discordance in the emergency department diagnosis of acute ischemic stroke. METHODS: This is a retrospective analysis of all acute ischemic stroke patients who received IV tissue plasminogen activator (tPA) in our emergency department between July 2011 and December 2015...
