INTRODUCTION: Chronic systematic inflammation has been suggested to be associated with the occurrence and development of cardiovascular events. Low-grade systematic inflammation persists in type 2 diabetes mellitus (T2DM) patients. In addition, the risk of cerebral hemorrhage in these patients is increased compared with non-diabetic patients. Neutrophil-to-lymphocyte ratio (NLR) is the ratio derived by dividing the neutrophil count with the lymphocyte count from a peripheral blood sample...

BACKGROUND: Our aim was to investigate the association of premature atrial complexes and the risk of recurrent stroke or death in patients with ischemic stroke in sinus rhythm. METHODS: In a prospective cohort study, we used 24-hour Holter recordings to evaluate premature atrial complexes in patients consecutively admitted with ischemic strokes. Excessive premature atrial complexes were defined as >14 premature atrial complexes per hour and 3 or more runs of premature atrial complexes per 24 hours...

BACKGROUND: Orthostatic hypotension (OH) is highly prevalent in the elderly, and this population can be exposed to serious complications, including falls and cognitive disorders, as well as overall mortality. However, the pathophysiology of OH is still poorly understood, and innovative methods of cerebral blood flow (CBF) assessment have been required to accurately investigate cerebrovascular reactivity in OH. OBJECTIVES: We want to compare brain tissue pulsatility (BTP) changes during an orthostatic challenge in elderly patients over 80 with and without OH...

BACKGROUND AND PURPOSE: Patients presenting with an intracerebral hemorrhage (ICH) generally have an initial noncontrast computed tomography (NCCT) of the brain. Computed tomography angiography (CTA) can help identify secondary causes of ICH and detect a "spot sign." We hypothesized that performing an urgent CTA in the setting of a presumed primary ICH has only limited utility and did not alter urgent management. METHODS: This was a retrospective study of consecutive patients presenting with a primary ICH identified from the Duke University Stroke Registry from 2010 to 2013 who had an ICH detected on an initial NCCT...

INTRODUCTION: Stroke risk is increased in cancer patients. Prognosis in these patients is poor, with higher in-hospital mortality and increased subsequent mortality. However, data on stroke in cancer patients are limited, specifically regarding acute stroke treatment and functional outcomes. We aim to determine the functional outcomes of cancer patients admitted with acute stroke. MATERIALS AND METHODS: We retrospectively reviewed patients carrying a diagnosis of cancer who were admitted with acute ischemic stroke between March 2013 and February 2016...

Rotation thromboelastometry is a viscoelastometric method that provides a rapid assessment of a patient's hemostatic processes in emergency settings, allowing prompt identification of specific coagulation abnormalities. Its results thus might guide targeted replacement therapy in hemorrhagic conditions, in case of platelet or coagulation factor deficiency, or hyperfibrinolysis, which is difficult to identify otherwise. Although currently used in emergency and traumatic surgery, there are limited data about thromboelastometry in ischemic stroke, particularly in monitoring the coagulative response to recombinant tissue plasminogen activator after intravenous thrombolysis (IVT)...

OBJECTIVE: Because some cryptogenic strokes may result from large-artery atherosclerosis that goes unrecognized as it causes <50% luminal stenosis, we compared the prevalence of nonstenosing intracranial atherosclerotic plaques ipsilateral to cryptogenic cerebral infarcts versus the unaffected side using imaging biomarkers of calcium burden. METHODS: In a prospective stroke registry, we identified patients with cerebral infarction limited to the territory of one internal carotid artery (ICA)...

BACKGROUND: Edaravone is widely used to treat acute ischemic stroke (AIS) within 24 hours of onset. We aimed to evaluate current edaravone treatment practices and the efficacy and safety of edaravone used with recombinant tissue plasminogen activator (tPA) in AIS patients within 4.5 hours of onset. The results were compared with those of the Safe Implementation of Treatments in Stroke-International Stroke Thrombolysis Registry (SITS-ISTR) study. METHODS: PROTECT4...

BACKGROUND: Chiropractic manipulation is a popular treatment for neck pain and headache, but may increase the risk of cervical artery dissection and stroke. Patients with carotid artery dissection can present with neck pain and/or headache before experiencing a stroke. These are common symptoms seen by both chiropractors and primary care physicians (PCPs). We aimed to assess the risk of carotid artery stroke after chiropractic care by comparing association between chiropractic and PCP visits and subsequent stroke...

BACKGROUND: Ultrasmall superparamagnetic iron oxide (USPIO)-enhanced magnetic resonance (MR) imaging enables the identification of inflammation within the atheroma, predominantly by USPIO uptake by macrophages present in atherosclerotic tissue. Diabetic patients, however, may have dysfunctional macrophage activity, which may affect utilization of USPIO in identifying plaque inflammation in this patient cohort. METHODS: Fifteen diabetic and fifteen nondiabetic patients underwent USPIO-enhanced carotid MR imaging using 1...

BACKGROUND: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited cerebral microangiopathy presenting with variable features, including migraine, psychiatric disorders, stroke, and cognitive decline and variable disability. On neuroimaging, CADASIL is characterized by leukoencephalopathy, multiple lacunar infarcts, and microbleeds. Previous studies suggest a possible role of endothelial impairment in the pathogenesis of the disease...

INTRODUCTION: The impact of atrial natriuretic peptide (ANP) value for predicting paroxysmal atrial fibrillation (pAF) in ischemic stroke patients remains uncertain. METHODS: The consecutive 222 ischemic stroke patients (median 77 [IQR 68-83] years old, 93 females) within 48 hours after onset were retrospectively studied. Plasma ANP and brain natriuretic peptide (BNP) levels were simultaneously measured at admission. Of all, 158 patients had no evidence of atrial fibrillation (AF) (sinus rhythm [SR] group), 25 patients had pAF (pAF group), and the other 39 patients had chronic AF (cAF group)...

BACKGROUND: Transcranial Doppler (TCD) is endorsed by national guidelines for use in aneurysmal subarachnoid hemorrhage (aSAH) for surveillance of cerebral vasospasm (CV). However, nationwide data on utilization of TCD for CV detection and monitoring in aSAH are lacking. METHODS: Analysis of nationwide trends in TCD prevalence was performed using Nationwide Inpatient Sample (NIS) data from 2002 to 2011. Raw counts were converted into weighted counts, which were used to generate national estimates...

BACKGROUND: Little is known about the micro-debris captured in filter-type distal embolic protection devices (EPD) used for carotid stenting (CAS). This study aimed to determine the histological and immunohistochemical characteristics of such debris by using a new liquid-based cytology (LBC) technique. METHODS: Fifteen patients who underwent CAS using a filter-type distal EPD (FilterWire EZ; Boston Scientific, Marlborough, MA, USA) were included in the study. After gross inspection of each recovered filter device, micro-debris were collected using a new LBC technique (SurePath; TriPath Imaging, Inc...

BACKGROUND AND PURPOSE: Preliminary studies have indicated that sulfonylurea drugs (SUD) may confer protection against cerebral swelling and hemorrhagic transformation in severe acute ischemic stroke (AIS). We sought to determine whether pretreatment and in-hospital use of SUD may be associated with better outcomes in diabetic AIS patients treated with intravenous thrombolysis (IVT). SUBJECTS AND METHODS: We analyzed consecutive diabetic AIS patients treated with IVT during a 3-year period...

BACKGROUND AND PURPOSE: Initial studies support the use of strength training (ST) as a safe and effective intervention after stroke. Our previous work shows that relatively aggressive, higher intensity ST translates into large effect sizes for paretic and non-paretic leg muscle volume, myostatin expression, and maximum strength post-stroke. An unanswered question pertains to how our unique ST model for stroke impacts skeletal muscle endurance (SME). Thus, we now report on ST-induced adaptation in the ability to sustain isotonic muscle contraction...

Central retinal artery occlusion (CRAO) is a devastating ocular emergency characterized by acute painless visual loss in the ipsilateral eye. We describe the case of acute non-arteritic CRAO associated fusiform internal carotid-ophthalmic artery aneurysm with intraluminal thrombus. Despite the rarity of this condition, we suggest that carotid-ophthalmic artery aneurysm should be included in the differential diagnosis of CRAO.

A 67-year-old right-handed woman experienced a sudden anterograde and retrograde short-term memory deficit that recovered on the next day. Magnetic resonance imaging (MRI) showed a spotty high-intensity lesion in the left putamen in the diffusion-weighted and fluid-attenuated inversion recovery images. Transient global amnesia due to lacunar infarction of the left putamen was diagnosed. Transient global amnesia is characterized by a sudden onset of anterograde amnesia that disappears within 24 hours. The cause of transient global amnesia is still uncertain...

BACKGROUND: This study aimed to analyze the effects of technical outcome of mechanical thrombectomy (MTE) on the associations between collateral status, assessed with pretreatment computed tomography angiography (CTA), and neurological and functional outcome, as well as associations between collaterals and metabolic risk factors (arterial hypertension, diabetes, hyperlipidemia, overweight). METHODS: Prospectively collected data of 115 patients with CTA-proven isolated middle cerebral artery occlusion treated successfully with MTE (Thrombosis in Cerebral Infarction [TICI] scale 2b or 3) were assessed retrospectively...
