Hemorrhagic transformation (HT) is one of the most feared complications of acute recanalization therapies. The aim of this study was to evaluate whether blood-brain barrier permeability (BBBP) imaging can predict HT in the setting of acute recanalization therapy and to determine the sensitivity and specificity of BBBP for the prediction of HT according to the type of reperfusion therapy. We assessed a total of 46 patients who received recanalization therapy (intravenous (IV) recombinant tissue plasminogen activator (tPA), mechanical thrombectomy with a stent retriever or both) for acute ischemic stroke within the internal carotid artery or middle cerebral artery...

Diabetes increases the risk of occurrence and poor functional recovery after ischemic stroke injury. Previously, we have demonstrated greater hemorrhagic transformation (HT), edema, and more severe functional deficits after stroke in diabetic animals that also presented with cerebral vasoregression and endothelial cell death in the recovery period. Given that Toll-like receptor 4 (TLR-4) activation in microvascular endothelial cells triggers a robust inflammatory response, we hypothesized that inhibition of TLR-4 signaling prevents endothelial cell death and improves outcomes after stroke...

Acute ischemic stroke is devastating to patients and their families because of few viable therapeutic options to promote recovery after reperfusion windows close. Recent breakthroughs in biotechnology have resulted in a reproducible patented process for the purification of extracellular vesicles (EVs) from human cardiosphere-derived cells (CDCs). Because CDC-EVs have many features potentially beneficial to treat acute ischemic stroke, CDC-EVs were evaluated in an established small-clot rabbit embolic stroke model, where clinically relevant end points were used to assess recovery in a more translational large animal model...

Estelle Everett, Nestoras Mathioudakis
PURPOSE OF REVIEW: Hyperglycemia occurs frequently in hospitalized patients with stroke and peripheral vascular disease (PVD). Guidelines for inpatient glycemic management are not well established for this patient population. We will review the clinical impact of hyperglycemia in this acute setting and review the evidence for glycemic control. RECENT FINDINGS: Hyperglycemia in acute stroke is associated with poor short and long-term outcomes, and perioperative hyperglycemia in those undergoing revascularization for PVD is linked to increased post-surgical complications...

BACKGROUND: Previous studies have reported slightly higher stroke rates in Takotsubo Syndrome compared to acute myocardial infarction. Our goal was to evaluate the temporal course of stroke rates and left ventricular recovery in patients with Takotsubo Syndrome. METHODS: We retrospectively examined the clinical and imaging data of 72 patients with Takotsubo Syndrome. The data collected came from January 2005 to March 2017. Left ventricular performance was evaluated by cardiovascular magnetic resonance imaging (MRI) in all patients during the acute phase of Takotsubo Syndrome and in a follow-up scan 2 months later...

BACKGROUND: The Systolic Blood Pressure Intervention Trial (SPRINT) was a randomized controlled trial which studied 9361 adults aged 50 and older with systolic blood pressure above 130mmHg and one or more cardiovascular risk factor. Patients were randomized to intensive (≤ 120mmHg) or standard (≤ 140mmHg) systolic targets. In August 2016, a limited dataset was released for secondary analysis. We hypothesized that excessive lowering of diastolic blood pressure could cause harm. Using the data from SPRINT, we sought to determine whether the development of diastolic hypotension during treatment was associated with adverse outcomes...

Cerebrovascular diseases of ischemic origin still remain the leading cause of death and disability of the population. In acute cerebral discirculation conditions, anaerobic glycolysis is activated, ATP formation rate decreases, the ion pumps work is disrupted and superoxide radicals are formed. Eventually, ionic asymmetry leads to the cytotoxic and vasogenic brain edema. Therefore, it is extremely important to induce simultaneous (complex) effect of medications on the key mechanisms of neuronal damage in process of survival of brain cells during acute ischemic stroke...

Background: The aim of the study was to determine the optimal set point for the critical event benchmarks described in stroke guidelines and validate the ability of these goals to predict successful administration of intravenous thrombolysis within 60 min of hospital arrival. Methods: This was a retrospective cohort analysis of patients with acute ischemic stroke who received intravenous thrombolysis following presentation to the emergency department. The national benchmarks for time intervals associated with the completion of critical events required to determine candidacy for thrombolysis were evaluated for the ability to predict successful administration of thrombolysis within 60 min of hospital arrival...

Dabigatran, a new oral anticoagulant, is a direct thrombin inhibitor used as an alternative to warfarin to reduce the risk of stroke and systemic embolism with nonvalvular atrial fibrillation. We report a case of a man who resumed dabigatran after 6 weeks of prior therapy and began experiencing hematuria with worsening kidney function. Renal biopsy with immunofluorescence and electron microscopy showed mesangial deposits consistent with immunoglobulin A nephropathy. With discontinuation of dabigatran and addition of methylprednisolone, the gross hematuria cleared and urine output improved...

Hemiplegic migraine is a common cause of acute brain attack in pediatrics. MR imaging sequences useful in differentiating hemiplegic migraine from other entities include arterial spin-labeling, SWI, MRA, and DWI. There has been limited exploration on the simultaneous use of these sequences in pediatrics. We present 12 pediatric patients with acute hemiplegic migraine or migraine with aura who underwent MR imaging within 12 hours of symptom onset. Quantitative and qualitative analyses were performed on arterial spin-labeling; and qualitative analysis, on SWI and MRA sequences...

OBJECTIVE: In observational cohorts, adiponectin is inversely associated and free fatty acids (FFAs) are directly associated with incident coronary heart disease (CHD). Adiponectin tends to be reduced and FFAs elevated in type 2 diabetes. We investigated relationships of adiponectin and FFA and major adverse cardiovascular events (MACEs) and death in patients with acute coronary syndrome (ACS) and type 2 diabetes using data from the AleCardio trial, which compared the PPAR-α/γ agonist aleglitazar with placebo...

INTRODUCTION: Haemorrhagic transformation is a major complication of acute ischaemic stroke (AIS). We sought to determine the predictors and clinical impact of intracranial haemorrhage (ICH) after revascularisation therapy. METHODS: We conducted a retrospective, single-centre study including 235 patients with AIS who underwent intravenous recombinant tissue plasminogen activator (IV-rtPA) therapy and/or endovascular treatment. A binary logistic regression model was used to determine the variables associated with ICH, parenchymal haematomas (PH), modified Rankin Scale (mRS) scores, and mortality...

Introduction: Patients with acute stroke are at high risk for infection. These infections are associated with unfavourable outcome after stroke. A prediction rule can identify the patients at the highest risk for strategies to prevent infection. We aim to develop a prediction rule for post-stroke pneumonia and other infections in patients with acute stroke. Patients and methods: We used data from the Preventive Antibiotics in Stroke Study, a multicentre randomised trial comparing preventive ceftriaxone vs...
