Synergistic protective effects of antioxidant and nitric oxide synthase inhibitor in transient focal ischemia. (1/2940)

Both nitric oxide synthase (NOS) inhibitors and free radical scavengers have been shown to protect brain tissue in ischemia-reperfusion injury. Nitric oxide and superoxide anion act via distinct mechanisms and react together to form the highly deleterious peroxynitrite. Therefore the authors examined the effects and the interaction between the NOS inhibitor, NG nitro-L-arginine (LNA) and the antioxidant/superoxide scavenger, di-tert-butyl-hydroxybenzoic acid (DtBHB) in the rat submitted to 2 hours of middle cerebral artery occlusion. Posttreatment was initiated 4 hours after the onset of ischemia and infarct volume was measured at 48 hours. The dose-related effect of LNA resulted in a bell-shaped curve: 15, 56, 65, and 33% reduction of total infarct for 0.03, 0.1, 0.3, and 1 mg/kg (intravenously [IV]) respectively and 11% increase in infarct volume for 3 mg/kg (IV). Whereas DtBHB (20 mg/kg; intraperitoneally [IP]) was ineffective, the dose of 60 mg/kg produced 65% protection in infarct volume. The combination of a subthreshold dose of LNA (0.03 mg/kg; IV) and DtBHB (20 mg/kg; IP) resulted in significant reduction (49%) in infarct volume. These results show that LNA and DtBHB act synergistically to provide a consistent neuroprotection against ischemic injury when administered 4 hours after ischemia. This suggests that nitric oxide and free radicals are involved and interact in synergy in ischemia-reperfusion injury.  (+info)

Changes in protein tyrosine phosphorylation in the rat brain after cerebral ischemia in a model of ischemic tolerance. (2/2940)

A brief period of sublethal cerebral ischemia, followed by several days of recovery, renders the brain resistant to a subsequent lethal ischemic insult, a phenomenon termed ischemic preconditioning or tolerance. Ischemic tolerance was established in the rat two-vessel occlusion model of ischemia, induced by occlusion of both carotid arteries in combination with hypotension. Ischemic preconditioning (3 minutes) provided maximal neuroprotection when induced 2 days prior to a lethal ischemic insult of 9-minute duration. Neuroprotection persisted for at least 8 weeks. Since neurotransmission has been implicated in ischemic cell death, the effect of ischemic preconditioning on tyrosine phosphorylation of proteins and on the levels of glutamate receptor subunits in hippocampus and neocortex was studied. Regional levels of tyrosine phosphorylation of proteins in general and the N-methyl-D-aspartate receptor subunit NR2 in particular are markedly enhanced after ischemia in nonconditioned brains, in both the synaptosomal fraction and the whole-tissue homogenate of rat neocortex and hippocampus, but recover to control levels only in the preconditioned brain. Ischemic preconditioning selectively induces a decrease in the levels of the NR2A and NR2B subunits and a modest decrease in the levels of NR1 subunit proteins in the synaptosomal fraction of the neocortex but not hippocampus after the second lethal ischemia. It was concluded that ischemic preconditioning prevents a persistent change in cell signaling as evidenced by the tyrosine phosphorylation of proteins after the second lethal ischemic insult, which may abrogate the activation of detrimental cellular processes leading to cell death.  (+info)

Combination therapy of fasudil hydrochloride and ozagrel sodium for cerebral vasospasm following aneurysmal subarachnoid hemorrhage. (3/2940)

Fasudil hydrochloride is a new type of intracellular calcium antagonist, different from the calcium entry blockers that are commonly employed for clinical use. Since September 1995, the combination of fasudil hydrochloride and ozagrel sodium, an inhibitor of thromboxane A2 synthesis, has been used to treat 60 patients at risk of cerebral vasospasm after aneurysmal subarachnoid hemorrhage. The effectiveness of this combination therapy was investigated by comparison with the outcome of 57 patients previously treated with only ozagrel sodium. The combination therapy was significantly more effective (p < 0.01) in reducing the incidence of low density areas on computed tomography scans, and reduced, but not significantly, the occurrence of symptomatic vasospasm. The combination therapy of fasudil hydrochloride and ozagrel sodium has superior effectiveness over only ozagrel sodium in treating patients at risk of vasospasm after aneurysmal subarachnoid hemorrhage.  (+info)

Modification of postsynaptic densities after transient cerebral ischemia: a quantitative and three-dimensional ultrastructural study. (4/2940)

Abnormal synaptic transmission has been hypothesized to be a cause of neuronal death resulting from transient ischemia, although the mechanisms are not fully understood. Here, we present evidence that synapses are markedly modified in the hippocampus after transient cerebral ischemia. Using both conventional and high-voltage electron microscopy, we performed two- and three-dimensional analyses of synapses selectively stained with ethanolic phosphotungstic acid in the hippocampus of rats subjected to 15 min of ischemia followed by various periods of reperfusion. Postsynaptic densities (PSDs) from both area CA1 and the dentate gyrus were thicker and fluffier in postischemic hippocampus than in controls. Three-dimensional reconstructions of selectively stained PSDs created using electron tomography indicated that postsynaptic densities became more irregular and loosely configured in postischemic brains compared with those in controls. A quantitative study based on thin sections of the time course of PSD modification indicated that the increase in thickness was both greater and more long-lived in area CA1 than in dentate gyrus. Whereas the magnitude of morphological change in dentate gyrus peaked at 4 hr of reperfusion (140% of control values) and declined thereafter, changes in area CA1 persisted and increased at 24 hr of reperfusion (191% of control values). We hypothesize that the degenerative ultrastructural alteration of PSDs may produce a toxic signal such as a greater calcium influx, which is integrated from the thousands of excitatory synapses onto dendrites, and is propagated to the neuronal somata where it causes or contributes to neuronal damage during the postischemic phase.  (+info)

Outcome of carotid artery occlusion is predicted by cerebrovascular reactivity. (5/2940)

BACKGROUND AND PURPOSE: The purpose of this study was to investigate the possibility of obtaining prognostic indications in patients with internal carotid occlusion on the basis of intracranial hemodynamic status, presence of previous symptoms of cerebrovascular failure, and baseline characteristics. METHODS: Cerebral hemodynamics were studied with transcranial Doppler ultrasonography. Cerebrovascular reactivity to apnea was calculated by means of the breath-holding index (BHI) in the middle cerebral arteries. Sixty-five patients with internal carotid artery occlusion were followed-up prospectively (median, 24 months), 23 patients were asymptomatic and 42 symptomatic (20 with transient ischemic attack and 22 with stroke). RESULTS: During the follow-up period, 11 symptomatic patients and 1 asymptomatic patient had another ischemic event ipsilateral to carotid occlusion. Among factors considered, only lower BHI values in the middle cerebral arteries ipsilateral to carotid occlusion and older age were significantly associated with the risk of developing symptoms (P=0.002 and P=0.003, respectively; Cox regression multivariate analysis). Based on our data, a cut point of the BHI value for distinguishing between pathological and normal cerebrovascular reactivity was determined to be 0.69. All patients except one, who developed TIA or stroke during the follow-up period, had BHI values ipsilateral to carotid occlusion of <0.69. CONCLUSIONS: These data suggest that impaired cerebrovascular reactivity is predictive for cerebral ischemic events in patients with carotid occlusion.  (+info)

Diffusion- and perfusion-weighted imaging in vasospasm after subarachnoid hemorrhage. (6/2940)

BACKGROUND AND PURPOSE: Better measures of cerebral tissue perfusion and earlier detection of ischemic injury are needed to guide therapy in subarachnoid hemorrhage (SAH) patients with vasospasm. We sought to identify tissue ischemia and early ischemic injury with combined diffusion-weighted (DW) and hemodynamically weighted (HW) MRI in patients with vasospasm after SAH. METHODS: Combined DW and HW imaging was used to study 6 patients with clinical and angiographic vasospasm, 1 patient without clinical signs of vasospasm but with severe angiographic vasospasm, and 1 patient without angiographic spasm. Analysis of the passage of an intravenous contrast bolus through brain was used to construct multislice maps of relative cerebral blood volume (rCBV), relative cerebral blood flow (rCBF), and tissue mean transit time (tMTT). We hypothesize that large HW imaging (HWI) abnormalities would be present in treated patients at the time they develop neurological deficit due to vasospasm without matching DW imaging (DWI) abnormalities. RESULTS: Small, sometimes multiple, ischemic lesions on DWI were seen encircled by a large area of decreased rCBF and increased tMTT in all patients with symptomatic vasospasm. Decreases in rCBV were not prominent. MRI hemodynamic abnormalities occurred in regions supplied by vessels with angiographic vasospasm or in their watershed territories. All patients with neurological deficit showed an area of abnormal tMTT much larger than the area of DWI abnormality. MRI images were normal in the asymptomatic patient with angiographic vasospasm and the patient with normal angiogram and no clinical signs of vasospasm. CONCLUSIONS: We conclude that DW/HW MRI in symptomatic vasospasm can detect widespread changes in tissue hemodynamics that encircle early foci of ischemic injury. With additional study, the technique could become a useful tool in the clinical management of patients with SAH.  (+info)

Estrogen provides neuroprotection in transient forebrain ischemia through perfusion-independent mechanisms in rats. (7/2940)

BACKGROUND AND PURPOSE: Estrogen-related neuroprotection in association with animal models of transient forebrain and focal ischemia has been documented in several recent reports. Some of those studies indicated that part of that benefit was a function of improved intraischemic vasodilating capacity. In the present study we examined whether chronic estrogen depletion and repletion affected ischemic neuropathology through perfusion-independent mechanisms. METHODS: Normal, ovariectomized (OVX), and OVX female rats treated with 17beta-estradiol (E2) were subjected to 30 minutes of transient forebrain ischemia (right common carotid occlusion plus hemorrhagic hypotension) and reperfusion. Neurological function and brain histopathology were assessed over the 72-hour recovery period. In all rats, preischemic and intraischemic cortical cerebral blood flow (CBF) levels were monitored with laser-Doppler flowmetry. In additional rats, CBF changes in the striatum and hippocampus were also monitored with laser-Doppler flowmetry probes and radiolabeled microspheres. In each experiment, the level of ischemia was targeted to a 75% to 80% reduction in cortical CBF. RESULTS: The similarity in ischemic severity among groups was supported by measurements of comparable patterns of electroencephalographic power changes during the ischemic period. Compared with normal females, OVX rats showed diminished neurological outcomes and more severe histopathology in the hippocampus and striatum. Two-week treatment of OVX rats with E2 was accompanied by postischemic neuropathological changes similar to those seen in normal females. Intraischemic CBF reductions in the hippocampus and striatum were similar in all groups (to 35% to 50% of the preischemic value) but significantly less than the cortical CBF reductions. CONCLUSIONS: These findings indicate that estrogen provides ischemic neuroprotection through mechanisms unrelated to improvement of intraischemic cerebral perfusion.  (+info)

Nitric oxide production in the CA1 field of the gerbil hippocampus after transient forebrain ischemia : effects of 7-nitroindazole and NG-nitro-L-arginine methyl ester. (8/2940)

BACKGROUND AND PURPOSE: The present study was designed to examine the time course of nitric oxide (NO) production and the source of NO in the CA1 field of the gerbil hippocampus after transient forebrain ischemia. METHODS: The production of NO in the CA1 field of the hippocampus after transient ischemia was monitored consecutively by measuring total NO metabolites (NOx-, NO2- plus NO3-) with the use of brain microdialysis. 7-Nitroindazole (7-NI) and NG-nitro-L-arginine methyl ester were used to dissect the relative contributions of neuronal NO synthase and endothelial NO synthase to the NO production. The histological outcomes of 7-NI in 5- and 10-minute global ischemia were also evaluated. RESULTS: The production of NO in the CA1 field of the hippocampus after ischemia was dependent on the severity of ischemia. Ischemia for 2 or 5 minutes did not induce a significant increase in NOx- levels in the CA1 field of the hippocampus after reperfusion, whereas the 10- and 15-minute ischemias produced significant and persistent increases in NOx- levels. 7-NI did not inhibit the basal NOx- levels and showed no effects on NOx- levels after 5 minutes of ischemia. However, it completely inhibited the increased NOx- levels after 10 or 15 minutes of ischemia. 7-NI provided minor neuroprotection in 5 minutes but not in 10 minutes of global ischemia. CONCLUSIONS: The increased NO level in the CA1 field of the hippocampus after ischemia is produced mostly by neuronal NO synthase, whereas the basal NO level mainly originates from endothelial NO synthase. The observed neuroprotective effect of 7-NI in 5-minute global ischemia in gerbils may not be due to neuronal NO synthase inhibition by this drug.  (+info)

N2 - We sought to determine whether treatment with felbamate was capable to reduce the accumulation of putrescine induced by transient forebrain ischemia in the Mongolian gerbil. Gerbils underwent 10 min ligation of common carotid arteries followed by recirculation. Immediately after the release of the arterial occlusion, felbamate (75 and 150 mg kg-1 i.p.) was administered. Putrescine and polyamine levels were measured in hippocampus and striatum at 1, 8, 24 and 48 h after recirculation. Putrescine levels appeared enhanced already 8 h after the release of the arterial occlusion and kept increasing up to 48 h in the hippocampus and striatum. No significant changes in spermidine levels during recirculation were detected. Conversely, ...
We studied silent stroke (i.e., infarcts on computed tomographic scan not related to later symptoms) in patients after transient ischemic attack or minor ischemic stroke.. Ours is a cross-sectional study of 2,329 patients who were randomized in a secondary prevention trial after transient ischemic attack or minor ischemic stroke and had no residual deficit after the qualifying event.. Silent stroke was observed in 13% of the 2,329 patients. Lacunes formed 79%, cortical lesions 14%, and border zone lesions 7% of all silent strokes. Silent lacunes were most often located in the basal ganglia and symptomatic lacunes most often in the corona radiata. Age, hypertension, and current cigarette smoking were related to the presence of silent stroke. Silent stroke was equally common in different types of transient ischemic attack, including transient monocular blindness. Residual symptoms of any kind were more common in patients with silent stroke than in those without.. Because only the sites of silent ...
article{f8148d83-783e-4da1-816a-c12a7ad72203, abstract = {,p,The expression of the mRNAs of nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), neurotrophin 3 (NT3) and the neurotrophin receptor, TrkB, was studied in the rat hippocampus by in situ hybridization following normothermic (37°C) and protective hypothermic (33°C) transient cerebral ischemia of 15 min duration. In the resistant dentate gyms, normothermic ischemia transiently induced NGF mRNA at around 8 h of recovery, while the NT3 mRNA levels were depressed over at least a 24-h recovery period. The levels of BDNF and TrkB were transiently and markedly elevated with a maximal expression at 24 h of recovery. Intraischemic hypothermia reduced the induction of NGF mRNA, while the increase of BDNF mRNA expression occurred earlier during recovery, and the post-ischemic NT3 mRNA depression was not affected. Also, the expression of TrkB mRNA was enhanced, and occurred concomitantly with the elevation of BDNF mRNA. In ...
To the Editor:. With great interest we read the study of Cucchiara et al1 about the usefulness of the ABCD score,2 developed by Rothwell et al. A 6-point score derived from the Oxfordshire Community Stroke Project cohort (age [≥60 years=1], blood pressure [systolic ,140 mmHg and/or diastolic ≥90 mmHg=1], clinical features [unilateral weakness=2, speech disturbance without weakness=1, other=0], and duration of symptoms in minutes [≥60=2, 10 to 59=1, ,10=0]; ABCD) was highly predictive of 7-day risk of stroke in the Oxfordshire cohort. In contrast to the Oxfordshire series, the ABCD score is not useful in a North American cohort of transient ischemic attack (TIA) patients. We are pleased to present a study with similar results. We test the ABCD score in 345 consecutive TIA patients attended within 24 hours by the vascular neurologist in the emergency room. Clinical data, symptom duration, neuroimaging and ultrasonographic (carotid and transcranial) findings were prospectively collected wihin ...
Among patients with a history of stroke/transient ischemic attack and prior VKA experience, switching to dabigatran was associated with an increased stroke/transient ischemic attack rate for both dabigatran doses compared with continuing on warfarin (D110 hazard ratio [HR] 1.99; 95% confidence interval [CI], 1.42-2.78; D150 HR 2.34; 95% CI, 1.60-3.41). Among prior stroke/transient ischemic attack patients who were new starters on dabigatran or warfarin, the rate of stroke/transient ischemic attack for both doses of dabigatran was similar to or lower than warfarin (D110 HR 0.64; 95% CI, 0.50-0.80; D150 HR 0.92l; 95% CI, 0.73-1.15). ...

Astrocytes play many roles essential for normal brain activity. The ability of these cells to recover after temporary focal cerebral ischemia is likely to be one important determinant of the extent of brain dysfunction and tissue damage. We have assessed astrocytic function based on the incorporation of radiolabel from 1-14C-acetate into glutamine at 1 hour of recirculation after middle cerebral artery occlusion for 2 or 3 hours in rats. There were marked differences in the response between subregions within the tissue subjected to ischemia, but the overall pattern of changes was similar after each ischemic period. The striatum, which forms part of the severely ischemic focal tissue during arterial occlusion, showed a large (44% to 68%) decrease in glutamine labeling compared with equivalent tissue from the contralateral hemisphere. In contrast, 14C-glutamine content was not significantly altered in perifocal tissue in the cerebral cortex, which was subjected to more moderate ischemia. Cortical ...

Background: Although by definition a transient ischemic attack (TIA) lasts less than 24 h, many patients experience cognitive complaints beyond focal symptom resolution. However, their prevalence, causes and profile are unclear. We therefore performed a systematic review on cognitive impairment after TIA. Summary: Medline and Embase were searched for relevant studies. Risk of bias was assessed, and data synthesis was performed according to the severity of cognitive impairment. Thirteen studies were included, with considerable heterogeneity concerning methods and timing of cognitive testing. Confounding, detection bias and attrition were the main causes of a high risk of bias in several studies. The prevalence of post-TIA mild cognitive impairment ranged from 29 to 68%. Severe cognitive impairment was found in 8-22% of patients. Studies using a cognitive screening instrument and those performed shortly after TIA or several years later, reported the highest frequencies of impairment. Patients
This study investigated the function of each of the hypoxia inducible factor (HIF) prolyl-4-hydroxylase enzymes (PHD1-3) in the first 24 h following transient focal cerebral ischaemia by using mice with each isoform genetically suppressed. Male, 8- to 12-week old PHD1−/−, PHD2+/− and PHD3−/− mice and their wild-type (WT) littermate were subjected to 45 min of middle cerebral artery occlusion (MCAO). During the experiments, regional cerebral blood flow (rCBF) was recorded by laser Doppler flowmetry. Behaviour was assessed at both 2 h and 24 h after reperfusion with a common neuroscore. Infarct volumes, blood-brain barrier (BBB) disruption, cerebral vascular density, apoptosis, reactive oxygen species (ROS), HIF1α, and glycogen levels were then determined using histological and immunohistochemical techniques. When compared to their WT littermates, PHD2+/− mice had significantly increased cerebral microvascular density and more effective restoration of CBF upon reperfusion. PHD2+/− mice
TY - JOUR. T1 - Asymmetrical protection of neostriatal neurons against transient forebrain ischemia by unilateral dopamine depletion. AU - Ren, Yubo. AU - Li, Xiaoda. AU - Xu, Zao C.. PY - 1997/7. Y1 - 1997/7. N2 - Neurons in the dorsal neostriatum are highly vulnerable to transient cerebral ischemia. It has been suggested that excessive dopamine release during ischemia may play an important role in the pathogenesis of postischemic cell death in the neostriatum. However, it remains controversial whether depletion of dopamine protects neurons in the neostriatum against ischemic insult. In the present study, transient forebrain ischemia was induced using the four-vessel occlusion method. Ischemic depolarization was used as an indication of completed ischemia. Under our experimental conditions, ischemia that produces ~21 min ischemic depolarization caused more than 90% of cell death in the dorsolateral neostriatum. Using such ischemia as a standard insult, the effect of dopamine depletion on ...
BACKGROUND AND PURPOSE: Many previous studies on dementia in stroke have restrictive inclusion criteria, which may result in underestimation of dementia rates. We undertook a large prospective population-based study of all transient ischemic attack and stroke to determine the impact of study entry criteria on measured rates of pre- and postevent dementia. METHODS: All patients with acute transient ischemic attack or stroke from a defined population of 92 728 are referred from primary care or at hospital admission to the Oxford Vascular Study (2002-2007) and have baseline clinical and cognitive assessment and follow-up. We examined the impact of early death, other nonavailability, and commonly used selection criteria, on measured rates of dementia. RESULTS: Among 1236 patients (mean age/SD 75.2/12.1 years, 582 men, 403 transient ischemic attack), 139 died or were otherwise unavailable for baseline assessment, 319 had prior dependency, 425 had comorbidity, 512 were aged ≥80 years, 85 were dysphasic, and
Endothelial progenitor cells (EPCs) play an important role in ischemic stroke. However, there are few studies on the relationship between EPC and nondisabling ischemic cerebrovascular events. Our aim was to investigate the association of EPCs and SDF-1 (serum stromal cell-derived factor-1) with NICE (nondisabling ischemic cerebrovascular events). TIA (transient ischemic attack) and minor stroke patients (153 in total) who had an onset of symptoms within 1 day were consecutively collected. 83 of the patients were categorized into the HR-NICE (high-risk nondisabling ischemic cerebrovascular event) group, and 70 of the patients were in the NHR-NICE (non-high-risk nondisabling ischemic cerebrovascular events) group. Adopted FCM (flow cytometry) was used to measure EPCs, taking double-positive CD34/KDR as EPCs. ELISA was used to measure the concentrations of serum SDF-1 and VEGF (vascular endothelial growth factor). By the sequence of admission time, 15 patients were selected separately from the HR-NICE
Transient global cerebral ischemia causes delayed neuronal death in the hippocampal CA1 region. It also induces an up regulation of cyclooxygenase 2 (COX-2), which generates several metabolites of arachidonic acid, known as prostanoids, including Prostaglandin I2 (PGI2). The present study investigated whether the PGI2 IP receptor plays an important role in brain injury after global cerebral ischemia in aged mice. Adult young (2-3 months) and aged (12-15 months) male C57Bl/6 wild-type (WT) or IP receptor knockout (IP KO) mice underwent a 12 min bilateral common carotid artery occlusion (BCCAO) or a sham surgery. Behavior tests (neurologic deficit and T-maze) were performed 3 and 7 days after BCCAO. After seven days of reperfusion, the numbers of cells positive for markers of neurons, astrocytes, microglia, myeloperoxidase (MPO) and phosphorylated CREB (p-CREB) were evaluated immunohistochemically. Interestingly, in young and aged IP KO ischemic mice, there was a significant increase (p < 0.01) in
BACKGROUND: People who have had a transient ischaemic attack (TIA) or non-disabling ischaemic stroke have an annual risk of major vascular events of between 4% and 11%. Aspirin reduces this risk by 20% at most. Secondary prevention trials after myocardial infarction indicate that treatment with vitamin K antagonists is associated with a risk reduction approximately twice that of treatment with antiplatelet therapy.. OBJECTIVES: To compare the efficacy and safety of vitamin K antagonists and antiplatelet therapy in the secondary prevention of vascular events after cerebral ischaemia of presumed arterial origin.. SEARCH METHODS: We searched the Cochrane Stroke Group Trials Register (last searched 15 September 2011), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 3), MEDLINE (2008 to September 2011) and EMBASE (2008 to September 2011).

It is however unknown if an intensive smoking cessation program is better than ordinary advise on smoking cessation during hospitalisation for stroke or transient ischemic attack.. The aim of the study was to assess if an intensive smoking cessation program made more patients stop smoking after stroke or transient ischemic attack.. Patients with stroke or transient ischemic attack are admitted to the department of neurology at Odense University hospital. Patient who are smokers on admission and age , 76 years, inhabitants in Funen County and with symptoms developed before admission will be offered participation in the study unless they have severe stroke, stroke more than 3 weeks before admission, other severe disease or unable to participate.. Study participants will be randomised to either usual short advise on smoking cessation or an intensive smoking cessation program. All participants will be ...
BACKGROUND AND AIMS: Transient cognitive impairment (TCI) on the Mini Mental State Evaluation score is common after transient ischemic attack/minor stroke and might identify patients at increased risk of dementia. We aimed to replicate TCI using the Montreal Cognitive Assessment (MoCA), compare it with persistent Mild Cognitive Impairment (PMCI), and to determine whether global cerebral hemodynamic changes could explain transient impairment. METHODS: Consecutive patients with transient ischemic attack/minor stroke (NIHSS ≤ 3) were assessed with the MoCA and transcranial Doppler ultrasound acutely and at 1 month. We compared patients with TCI (baseline MoCA | 26 with ≥ 2 points increase at 1 month), PMCI (MoCA | 26 with | 2 points increase), and no cognitive impairment (NCI; MoCA ≥ 26). RESULTS: Of 326 patients, 46 (14.1%) had PMCI, 98 (30.1%) TCI, and 182 (55.8%) NCI. At baseline, TCI patients had higher systolic blood pressure (150.95 ± 21.52 vs 144.86 ± 22.44 mmHg, p = 0.02) and lower cerebral

BACKGROUND: The risk of recurrent stroke is up to 10% in the week after a transient ischaemic attack (TIA) or minor stroke. Modelling studies suggest that urgent use of existing preventive treatments could reduce the risk by 80-90%, but in the absence of evidence many health-care systems make little provision. Our aim was to determine the effect of more rapid treatment after TIA and minor stroke in patients who are not admitted direct to hospital. METHODS: We did a prospective before (phase 1: April 1, 2002, to Sept 30, 2004) versus after (phase 2: Oct 1, 2004, to March 31, 2007) study of the effect on process of care and outcome of more urgent assessment and immediate treatment in clinic, rather than subsequent initiation in primary care, in all patients with TIA or minor stroke not admitted direct to hospital. The study was nested within a rigorous population-based incidence study of all TIA and stroke (Oxford Vascular Study; OXVASC), such that case ascertainment, investigation, and follow-up were
Background and aim: Published data suggest that patients with cerebral ischaemia and atrial fibrillation (CIAF) have higher inhospital mortality than patients with cerebral ischaemia of arterial origin (CIAO). Data on long term risks are scarce. We compared the long term risks of death and vascular events (VE) between these groups.. Methods: We extended the follow-up of 2473 patients from the Dutch TIA Trial (recruitment March 1986 to March 1989, all treated with aspirin; CIAO) and 186 Dutch participants of the European Atrial Fibrillation Trial (recruitment June 1988 to May 1992, 26% on anticoagulants during the trial; CIAF). Hazard ratios (HRs) for death and VE of CIAF versus CIAO were analysed by means of Cox regression analysis and adjusted for age, sex and several cardiovascular risk factors.. Results: After a mean follow-up of 10.1 years, 1484 patients with CIAO had died and 1336 had suffered at least one VE (377 cardiac, 455 stroke). Mean follow-up of the CIAF patients was 6.8 years; 150 ...

Clarification of the pathophysiological mechanisms of intra-arterial thromboembolism may lead to novel treatments for cerebrovascular disease. There is increasing evidence for the role of von Willebrand factor (VWF) cleaving protease (ADAMTS-13) in modulating the thrombotic cascade in high flow arterial settings. VWF multimers are rich in ultra large forms (ULVWF) which can rapidly bind its primary platelet receptor resulting in spontaneous aggregation of platelets. Under normal conditions, these ULVWF are regulated by rapid proteolysis converting them to smaller, less active forms. The protease responsible for cleavage of ULVWF is ADAMTS-13. We measured the ADAMTS-13 antigen and ADAMTS-13 activity levels in the plasma of consecutive patients with transient ischaemic attack (TIA), compared with nonstroke controls, in a hospital based TIA clinic. This was compared with VWF levels. Samples were analysed in the acute phase and at 3 months postevent. In our pilot study patients with partial anterior ...

Immunohistochemistry and Western blot analysis were performed at 2 days, 7 days, 14 days, and 28 days after 90 min of transient middle cerebral artery occlusion (tMCAO) in mice. This study showed that mitochondrial fission protein dynamin-related protein 1 (Drp1) and fusion protein optic atrophy 1 (Opa1) were both upregulated in the ischemic penumbra, with the peak at 2 days after tMCAO, whereas phosphorylated-Drp1 (P-Drp1) progressively increased with a peak at 14 days after tMCAO. Double-immunofluorescence analysis showed many Drp1/cytochrome c oxidase ...
BACKGROUND AND PURPOSE: The ABCD(2) score predicts the early risk of stroke after transient ischemic attack (TIA). However, data on the severity of recurrent events would also be useful. Do patients with high scores also have more severe early recurrent strokes, perhaps further justifying hospital admission? Do patients with low scores have a low early risk of recurrent TIA as well as recurrent stroke? METHODS: We completed a prospective, population-based study in Oxfordshire, England, of 500 consecutive patients presenting with TIA from April 1, 2002, by using multiple methods of case ascertainment (Oxford Vascular Study). Recurrent TIA, minor stroke, and major stroke (National Institutes of Health Stroke Scale score |3 at the time of first assessment) were identified by face-to-face follow-up. Predictive value was expressed as the area under the receiver operating characteristic curve. RESULTS: Of 500 patients with TIA, 55 had a recurrent TIA (11.0%; 95% CI, 8.3% to 13.7%) and 50 had a recurrent
A transient ischemic attack (TIA), also known as a mini stroke, is a brief episode where symptoms similar to those of a stroke are present. The cause of a TIA is a temporary decrease in blood supply to a part of the brain. Similar to an ischemic stroke, an attack occurs when a clot or plaque buildup decreases blood flow to a part of the brain. But unlike a stroke, a TIA does not have a lasting effect, as it only decreases the blood flow, and does not usually cause permanent tissue damage. Many TIAs last less than 5 minutes, and symptoms can include sudden weakness in one side of the body, blurred vision, vertigo or sudden, severe headache with no known cause. Sometimes, the clots that caused the transient ischemic attack may spontaneously dissolve.. While TIAs are temporary and symptoms are brief, it is still crucial to immediately seek emergency care. Transient ischemic attacks are usually indicators of partially blocked or narrowed arteries, and are often precursors to full-blown strokes ...

BACKGROUND AND PURPOSE: Long-term outcome information after transient ischemic attack (TIA) and stroke is required to help plan and allocate care services. We evaluated the impact of TIA and stroke on disability and institutionalization over 5 years using data from a population-based study. METHODS: Patients from a UK population-based cohort study (Oxford Vascular Study) were recruited from 2002 to 2007 and followed up to 2012. Patients were followed up at 1, 6, 12, 24, and 60 months postevent and assessed using the modified Rankin scale. A multivariate regression analysis was performed to assess the predictors of disability postevent. RESULTS: A total of 748 index stroke and 440 TIA cases were studied. For patients with TIA, disability levels increased from 14% (63 of 440) premorbidly to 23% (60 of 256) at 5 years (P=0.002), with occurrence of subsequent stroke being a major predictor of disability. For stroke survivors, the proportion disabled (modified Rankin scale |2) increased from 21% (154 of 748)

In this study, we compared the cellular localization, expression, and activity of MMP-2 and -9 in relation to the evolution of neuronal damage 24 and 72 h after transient global ischemia. In response to ischemia, there was a generalized increase in cellular MMP-2 immunoreactivity at 24-h reperfusion (in neurons, glia and vessels) whereas at 72-h reperfusion the increase in MMP-2 was predominantly in glia. These glial alterations contributed to a significant increase in pro MMP-2 levels in ischemic regions (P ,0.01) ...

AU - Pan, Bai Shen. AU - Manji, Husseini K.. AU - Potter, William Z.. PY - 1995. Y1 - 1995. N2 - We examined alterations in the cyclic AMP generating system and G protein subunits in gerbil hippocampus following 10 min of transient ischemia. In hippocampal slices, basal and isoproterenol- and forskolin-stimulated cyclic AMP accumulations were markedly increased at 6 and 24 h after ischemia. Interestingly, both the inhibition of forskolin-stimulated cyclic AMP and the potentiation of β-adrenoceptor-stimulated cyclic AMP by a γ-aminobutyric acid(B) receptor agonist were attenuated at these time points. Ischemia did not affect the immunolabeling of any of the G protein α subunits; only that of β subunits was significantly decreased, by 28.2%, 4 days after ischemia. In contrast, pertussis toxin-catalyzed ...

Background and Purpose: Few studies have evaluated long-term costs after stroke onset, with almost no cost data for transient ischemic attack (TIA). We studied hospital costs during the 5 years after TIA or stroke in a population-based study. Methods: Patients from a United Kingdom population-based cohort study (Oxford Vascular Study) were recruited from 2002 to 2007. Analysis was based on follow-up until 2010. Hospital resource usage was obtained from patient hospital records and valued using 2008/2009 unit costs. Because not all patients had full 5-year follow-up, we used nonparametric censoring techniques. Results: Among 485 TIA and 729 stroke patients ascertained and included, mean censor-adjusted 5-year hospital costs after index stroke were $25 741 (95% confidence interval, 23 659-27 914), with costs varying considerably by severity: $21 134 after minor stroke; $33 119 after moderate stroke; and $28 552 after severe stroke. For the 239 surviving stroke patients who had reached final follow-up,
Abstract: Recent studies have focused on elucidating the contribution of individual complement proteins to post-ischemic cellular injury. As the timing of complement activation and deposition after cerebral ischemia is not well understood, our study investigates the temporal pattern of C1q accumulation after experimental murine stroke. Brains were harvested from mice subjected to transient focal cerebral ischemia at 3, 6, 12, and 24 hr post reperfusion. Western blotting and light microscopy were employed to determine the temporal course of C1q protein accumulation and correlate this sequence with infarct evolution observed with TTC staining. Confocal microscopy was utilized to further characterize the cellular localization and characteristics of C1q deposition. Western Blot analysis showed that C1q protein begins to accumulate in the ischemic hemisphere between 3 and 6 hr post-ischemia. Light microscopy confirmed these findings, showing concurrent C1q protein staining of neurons. Confocal ...
Transient forebrain ischemia results in delayed neuronal death in the CA1 region of the hippocampus after injury, which is, at least in part, a consequence of excessive generation of reactive oxygen species. Previous in vitro studies using cell cultures or brain slices have demonstrated that phospholipase D (PLD) in the nervous system is involved in the signaling mechanism in response to a variety of agonists. Several recent studies have shown that reactive oxygen species stimulate phospholipase D (PLD) activity in several kinds of cells. Therefore, this raises the possibility that PLD activity is enhanced in the ischemic brain. Meanwhile, osteopontin (OPN) was initially identified as a sialoglycoprotein in bone, but has since been found in various tissues. Although not much is known about its function, OPN seems to play an important role in inflammation and tissue repair. Recently, it was reported that OPN was upregulated in the activated microglia after focal brain ischemia, suggesting that OPN might

The present study was performed in 34 patients with transient cerebral ischemia, TCI. Twenty-four of the patients were examined angiographically. Atherosclerotic abnormalities were demonstrated in 13 and a total occlusion of the interior carotid artery was found in one patient. The angiograms were normal in 10 patients. One patient suffered from hyperlipoproteinemia, type IV, and one from diabetes mellitus. The platelet aggregation in vitro was increased significantly, as more patients than normal controls showed secondary aggregation with low ADP-concentration: less than or equal to 1 mumol (p less than 0.001). The fibrinolytic capacity was significantly reduced (p less than 0.01) but not particularly in the patients with increased tendency for platelet aggregation. No correlation found between changes in platelet aggregation, the fibrinolytic activity and the angiographic findings. The results described may favor the concept that a prophylactic use of drug excerting an antiaggregation effect on

CSCA has enrolled 433 264 patients with acute stroke/TIA from 1576 hospitals. The patient and hospital baseline characteristics were reported. Compared with the previous hospitalised stroke registries, CSCA represents a large-scale effort to translate efficacy into effectiveness in stroke/TIA care for hospitalised patients covering all regions of China (except for Hong Kong, Taiwan and Macao regions). Patients with IS from CSCA have the similar patients demographic and clinical characteristics of China National Stroke Registry (CNSR) I and II, such as patients age, race, history of stroke/TIA, hypertension disease and diabetes mellitus.14 This programme also provides a unique platform to track the characteristics, process of care and outcomes of patients with stroke/TIA. Specifically, the CSCA provides opportunities to promote stroke centre construction and increase adherence to evidence-based performance metric in clinical practice. Through the CSCA, participating hospitals self-assess their ...
Cerebrovascular disorders (CVD) are a complex medical problem with a wide variety of different etiologies. Symptoms are often atypical and subtle. Diagnostic methods are often invasive. Many autors have tried to find a noninvasive method which could be a screening method. This is Transcranial-Duplex-Doppler ulstrasonography (TCDD). We use it in patients with pulsating headache, vertigo, seizures, hemiparesis and other neurologic dysabillities. Here, we present eight patients between the ages of 1-16, with cerebrovascular disorders. Six of them had ischemic cerebral infarction. Their cerebral circulation was examined by TCDD. We found reduced cerebral blood flow at the site of the ischemic lesion, as a sign of hypoperfusion. Control TCDD findings were normal in patients with transient ischemic attacks, but are unchanged in patients with ischemic insult. Patients with stenosis of the cerebral arteries had typical TCDD findings. Treatment of CVD is often insufficient, because they often cause ...

The air-dried aerial parts of Lavandula angustifolia Mill, a traditional Uygur herbal drug, is used as resuscitation-inducing therapy to treat neurodisfunctions, such as stroke. This study was designed to assess the neuroprotective effects of lavender oil against ischemia/reperfusion (IR) injury in mice. Focal cerebral ischemia was induced by the intraluminal occlusion method with a nylon string. The neurodysfuntion was evaluated by neurological deficit and the infarct area was showed by 2,3,5-triphenyltetrazolium chloride (TTC) staining. The histopathological changes were observed by hematoxylin and eosin staining. The levels of mitochondria-generated reactive oxygen species (ROS), malondialdehyde (MDA) and carbonyl, the ratio of reduced glutathione (GSH)/glutathione disulfide (GSSG), the activities of superoxide dismutase (SOD), catalase (CAT) and glutathion peroxidase (GSH-Px) in brain tissue were measured to estimate the oxidative stress state. Neurological deficit, infarct size, histopathology
OBJECTIVES: An inflammatory process following stroke in human brains and systemic inflammatory responses after stroke in humans have been reported by numerous investigators. The aim of the study was to investigate if genes involved in the cyclooxygenase 2 (COX-2) pathway are upregulated at peripheral level in patients after transient ischaemic attack (TIA) and stroke. DESIGN OF STUDY: Blood samples were obtained from two groups of patients undergoing carotid endarterectomy ...
This is the sudden transient loss of vision in one eye (like a curtain or shade coming from above or below) due to the passage of an embolus through the retinal vessels from ipsilateral carotid vessel disease. It is a feature of a TIA in the carotid artery circulation and is often the first clinical evidence of carotid stenosis.5 About 20% of all TIAs present as amaurosis fugax.6 Amaurosis fugax may forewarn of the development of hemiparesis or blindness and should be considered a matter for urgent attention and rectification. Give aspirin immediately. Carotid endarterectomy may be required for high grade stenosis. ...
Overall, 18.3% of pseudoaneurysms were intracranial and 81.7% were extracranial, and the average size was 7.3 mm. The mean follow-up time was 29.3 months; 3.3% of patients had a recurrent transient ischemic attack, no patients had a recurrent stroke, and 14.2% of patients had recurrence of nonischemic symptoms (headache, neck pain, Horner syndrome, or cranial nerve palsy). Follow-up imaging demonstrated that 13.8% of pseudoaneurysms had enlarged, 30.2% had healed, and 56% had remained stable. In total, 20.8% of patients had an intervention other than medical treatment. Interventions included stenting, coiling, flow diversion, and clipping. Predictors of intervention included increasing size, size , 10 mm, location in the C2 (petrous) segment of the internal carotid artery (ICA), younger age, hyperlipidemia, pseudoaneurysm enlargement, and any symptom development. Significant predictors of enlargement included smoking, history of trauma, C2 location, hyperlipidemia, and larger initial ...

Neuroprotection remains an unmet need in the treatment of ischemic stroke. Disappointing data were obtained in clinical studies with ionotropic glutamate receptor antagonists in stroke owing to the strong impact of these drugs on fast excitatory synaptic transmission in the CNS, and the opposite role played by synaptic and extrasynaptic N-methyl-D-aspartate (NMDA) receptors in neurodegeneration/neuroprotection [1-19]. In addition, NMDA receptor antagonists impair mechanisms of activity-dependent synaptic plasticity and may cause severe adverse effects, such as psychotomimetic effects and intrinsic neurotoxicity [1]. mGlu receptor ligands modulate synaptic transmission, and are therefore considered as more valuable candidate targets for neuroprotective drugs. The mGlu receptor ligands developed so far for the treatment of CNS disorders have shown a good profile of safety and tolerability, which may reflect the modulatory role of mGlu receptors in synaptic transmission and activity-dependent ...
BACKGROUND AND PURPOSE Newborn cells may participate in repair following ischemic brain injury, but their survival and function may be influenced by inflammation. METHODS We investigated the effects of indomethacin, a nonsteroidal antiinflammatory drug, on the fate of newborn cells following transient focal ischemia. RESULTS Bromodeoxyuridine (BrdU)-labeled cells, including migrating neuroblasts, were observed in the neighboring striatum and overlying cortex 1 day poststroke. The density of BrdU+ cells labeled with doublecortin, nestin, glial fibrillary acidic protein, or NG2 was increased at 14 and 28 days. Indomethacin increased BrdU+ cells of all lineages and reduced microglial/monocyte activation. CONCLUSIONS Indomethacin enhanced the accumulation of newborn cells following stroke.
A 59-year-old Hispanic man presented with right upper and lower extremity weakness, associated with facial drop and slurred speech starting 2 hours before the presentation. He denied visual disturbance, headache, chest pain, palpitations, dyspnea, dysphagia, fever, dizziness, loss of consciousness, bowel or urinary incontinence, or trauma. His medical history was significant for uncontrolled type 2 diabetes mellitus, hypertension, hyperlipidemia, and benign prostatic hypertrophy. Social history included cigarette smoking (1 pack per day for 20 years) and alcohol intake of 3 to 4 beers daily. Family history was not significant, and he did not remember his medications. In the emergency department, his vital signs were stable. His physical examination was remarkable for right-sided facial droop, dysarthria, and right-sided hemiplegia. The rest of the examination findings were insignificant. His National Institutes of Health Stroke Scale (NIHSS) score was calculated as 7. Initial CT angiogram of ...
There have been several examinations in the USA and we are also observing it with concern in European countries such as Italy, Spain and Germany: Significantly fewer patients with minor strokes come to the clinics and are there on stroke units - departments specializing in stroke patients in the hospital - treat. We fear that this will have an indirect impact of the pandemic because people are afraid of getting infected in the hospital and therefore do not take stroke warning symptoms as seriously as they should. Every second stroke there are volatile symptoms, also known as transient ischemic attack (TIA) or mild stroke. And these precede severe strokes. At the moment we cannot really assess the impact of the pandemic, but we fear that severe strokes will end up being more common than before. And not just because of the virus, but mainly because those affected do not go to the clinic if there are warning signs.. The Transient ischemic attack - in short TIA - is considered a harbinger of a ...

BACKGROUND: The interval between the onset of cerebral vessel occlusion and recanalization has been shown to be an independent predictor of poor outcomes. However, endovascular recanalization of symptomatic cerebral vessel occlusion in the subacute period has not been well documented. We investigated the safety and efficacy of subacute recanalization of occluded cerebral vessels in patients with ischemic stroke or transient ischemic attacks (TIAs). METHODS: Between 2014 and 2015, 98 patients were admitted to the emergency room for ischemic stroke or TIA with a small infarct core, which was defined as modest early ischemic change on non-contrast CT or overt diffusion-perfusion mismatch ...
The availability of an in-house, around-the-clock interventional cardiology team dramatically decreases the time it takes to restore blood flow to heart attack patients, according to data presented this week. These findings were reported by researchers from Loyola University Health System (LUHS) at the American College of Cardiology annual meeting in New Orleans.
Results A total of 6,762 (88%) and 940 (12%) CKD-free patients and 2,025 (90%) and 231 (10%) CKD patients took dabigatran 110 mg and 150 mg twice daily, respectively. Dabigatran was associated with a lower risk of AKI than warfarin for either the CKD-free (hazard ratio [HR]: 0.62; 95% confidence interval [CI]: 0.49 to 0.77; p less than 0.001) or CKD (HR: 0.56; 95% CI: 0.46 to 0.69; p less than 0.001) cohort. As the increment in CHA2DS2-VASc score (a risk score based on congestive heart failure, hypertension, age 75 years or older, diabetes mellitus, previous stroke/transient ischemic attack, vascular disease, aged 65 to 74 years, and female sex) increased from 0/1 to 6+ points, the incidence of AKI for the dabigatran group was relatively stable (1.87% to 2.91% per year for the CKD-free cohort; 7.31% to 13.15% per year for the CKD cohort) but increased obviously for patients taking warfarin for either CKD-free (2.00% to 6.16% per year) or CKD cohorts (6.82 to 26.03% per year). The warfarin group ...
Stroke is a common diagnosis in primary care and it is the third leading cause of death in Americans. Primary care clinicians provide stroke care to three main groups of patients: (1) patients at high risk of stroke requiring primary prevention, (2) patients with a history of stroke requiring secondary prevention, or (3) patients with signs and symptoms consistent with acute stroke, requiring urgent care. The purpose of this chapter is to review the ...
