Abstract

Objective: Lower serum low-density lipoprotein cholesterol (LDL-C) levels are associated with increased intracerebral hemorrhage (ICH) risk. However, reverse causality and residual confounding has not attracted public attention. Therefore, we assessed whether people with LDL-C have increased risk of mortality adjusting for potential confounders using two large Taiwan cohorts.Methods: The Mei-Jhao (MJ) cohort has 414,372 adults participating in a medical screening program with 378 ICH deaths within 15 years of follow-up (1994–2008). Cox proportional hazards regressions estimated hazard death ratios according to LDL-C levels. We identified 4,606 ICH patients from the Taiwan Stroke Registry (TSR) and analyzed the impact of LDL-C on 3-month mortality.Results: Low cholesterol (LDL-C

Abstract

Cardiovascular fitness exerts directly beneficial effects on functional and cognitive outcomes in patients of chronic stroke. However, the effect of early rehabilitation on cardiovascular function has not yet been thoroughly examined. We tested whether complementary rehabilitation program could influence cardiovascular fitness in an early stage of stroke patients. The associations for post-acute stroke functional recovery with cardiovascular fitness were explored. Thirty-seven patients with mean poststroke interval of 8.6 ± 3.8 days underwent inpatient rehabilitation of 22.8 ± 3.8 days. Functional outcomes of 15.3 points (17.2%) in functional independence measure improved after rehabilitation program. The therapeutic cardiovascular fitness was determined in ramp exercise test on a cycling ergometer. Peak oxygen uptake (V˙O2peak) significantly increased by 24.8% after early stroke rehabilitation. Multivariate regression analysis was performed to assess for associations of functional improvement with respect to change in V˙O2peak and extremities motor impairment. V˙O2peak gain accounted for more functional recovery than extremities motor improvement (R2 = 0.42). In conclusion, these results suggest that cardiovascular fitness appears to increase after complementary program in early stroke rehabilitation, and better cardiovascular fitness may be associated with greater functional improvement.

Abstract

The combined effects of metabolic syndrome and the apolipoprotein E and CYP46 genotypes on the risk of cognitive decline has yet to be determined among Taiwanese Chinese. Two hundred and nine mentally healthy middle-aged and older adults were assessed for metabolic syndrome, cognitive function using the Cognitive Abilities Screening Instrument, Mini-Mental State Examination, ApoE, and CYP46 polymorphisms. There were no differences in cognitive performance, ApoE epsilon4 (ε4) carrier status, or CYP46 genotypes between participants with and those without metabolic syndrome. The ε4 carriers and participants with the AA allele of CYP46 had significantly lower mental manipulation score. Metabolic syndrome and ε4 had synergistic effects on cognitive decline. Therefore, the ε4 carriers and participants with the AA allele of CYP46 have decreased mental manipulation ability. The metabolic syndrome may play a role in subtle cognitive dysfunction in ε4 carriers among Taiwanese Chinese.

Abstract

Vertigo can be a major presentation of posterior circulation stroke and can be easily misdiagnosed because of its complicated presentation. We thus prospectively assessed the predictive value of vertebral artery extracranial color-coded duplex sonography (ECCS) for the prediction of ischemic stroke-related vertigo. The inclusion criteria were: (1) a sensation of whirling (vertigo); (2) intractable vertigo for more than 1 hour despite appropriate treatment; and (3) those who could complete cranial magnetic resonance imaging (MRI) and vertebral artery (V2 segment) ECCS studies. Eventually, 76 consecutive participants with vertigo were enrolled from Kaohsiung Municipal Hsiao-Kang Hospital, Kaohsiung, Taiwan between August 2010 and August 2011. Demographic data, neurological symptoms, neurologic examinations, and V2 ECCS were assessed. We chose the parameters of peak systolic velocity (PSV), end diastolic velocity (EDV), PSV/EDV, mean velocity (MV), resistance index (RI), and pulsatility index (PI) to represent the hemodynamics. Values from both sides of V2 segments were averaged. We then calculated the average RI (aRI), average PI (aPI), average PSV (aPSV)/EDV, and average (aMV). Axial and coronal diffusion-weighted MRI findings determined the existence of acute ischemic stroke. We grouped and analyzed participants in two ways (way I and way II analyses) based on the diffusion-weighted MRI findings (to determine whether there was acute stroke) and neurological examinations. Using way I analysis, the “MRI (+)” group had significantly higher impedance (aRI, aPI, and aPSV/EDV ratio) and lower velocity (aPSV, aEDV, and aMV(PSV + EDV/2)), compared to the “MRI (–)” group. The cutoff value/sensitivity/specificity of aPSV, aEDV, aMV, aPI, aRI, and aPSV/EDV between the MRI (+) and MRI (–) groups were 41.15/61.5/66.0 (p = 0.0101), 14.55/69.2/72.0 (p = 0.0003), 29.10/92.1/38.0 (p = 0.0013), 1.07/76.9/64.0 (p = 0.0066), 0.62/76.9/64.0 (p = 0.0076), and 2.69/80.8/66.0 (p = 0.0068), respectively. Using way II analysis, lower aEDV and aMV, and higher aRI, aPI, and aPSV/EDV ratio could determine the “MRI (+) without focal signs” group. The cutoff value/sensitivity/specificity of aEDV, aMV, aPI, aRI, and aPSV/EDV between the MRI (+) without focal signs and MRI (–) groups were 9.10/71.4/96.0 (p = 0.0005), 15.65/57.1/96.0 (p = 0.0124), 1.10/100/70.0 (p = 0.0002), 0.64/100/70.0 (p = 0.0023), and 2.80/100/70.0 (p = 0.0017), respectively. In conclusion, using demographic data and clinical symptoms, it was difficult to determine the patients with ischemic stroke-related vertigo. Although neurological examinations still have diagnostic value, the high impedance and low velocity pattern of V2 ECCS can be an add-on method for the screening of acute ischemic stroke-related vertigo, even for those without focal neurological signs.

Abstract

Frontal lobes are great and are a late-developing region of the neocortex that play a critical role in human behavior and executive function. The aim of this study was to clarify the role of event-related potentials (ERPs) in executive dysfunction and its relationship between generator mechanism and cognitive significance. We recruited 20 patients with frontal lobe lesion (FLL) and 27 age-matched controls. All patients submitted to comprehensive Frontal Test Battery and auditory ERPs measurement. In comparison with controls, the patients with FLL had significantly decreased executive function and manifested the delay of P300 latency, which reflected a delay of mental processing speed in these patients. Our findings suggest that patients with FLL may have prolonged P300 latency, which has a good correlation with executive dysfunction, poor performance, and longer P300 latencies. P300 ERPs are considered to be a useful method to identify the alteration of frontal-parietal connection.

Abstract

Circadian variation of the onset time of acute ischemic stroke has been well studied. However, little is mentioned about the circadian variation of discharge-stroke severity and discharge-functional status. This study evaluated the impact of onset time on discharge-stroke severity and the functional status of acute ischemic stroke. Brain magnetic resonance imaging was performed on 274 acute ischemic stroke patients (66.42% male; mean age = 64.81 ± 12.80 years). All times of onset were assigned to 4-hourly periods (six groups) starting from midnight. Stroke severity/functional status was evaluated on admission and discharge using the National Institute of Health Stroke Scale (NIHSS) score/modified Rankin Scale (mRS) and Barthel Index (BI), respectively. Using mRS, but not NIHSS score and BI, it was possible to differentiate the best and worst groups on discharge. Patients in group 2 (4 to

Abstract

Cardiac autonomic dysfunction is a common complication after acute ischemic stroke (IS). Prior investigators have emphasized that infarction of brain stem or hemispheres with insular involvement is related to this dysfunction and may predict poor clinical outcome. From the viewpoint of stroke physicians, however, all stroke patients, particularly large-artery atherosclerosis (LAA) should be monitored for possible cardiac complications after acute IS. This study aimed to investigate cardiac autonomic impaction in patients with acute IS and to make the comparison between LAA and small-vessel occlusion (SVO) subtypes. Of the 126 acute IS patients prospectively enrolled in this study, 32 had LAA, 56 had SVO, and 38 had undetermined etiology according to the Trial of Org 10172 in Acute Stroke Treatment criteria. Cardiac autonomic function of all patients was assessed by measuring heart rate variability (HRV). The low- and high-frequency components of HRV in all stroke patients were significantly lower than those of control subjects after comparing multivariable models, including additional adjustments for age, gender, and all risk factors. There were no significant differences on HRV between LAA and SVO although post hoc comparisons showed that stroke patients of SVO had increased sympathetic modulation and reduced vagal activity. In conclusion, in acute IS patients, both LAA and SVO are predisposed to have cardiac autonomic dysfunction, manifesting as abnormalities in HRV, whether in hemispheric or brain stem lesions. Stroke patients of SVO are at higher risks of cardiac abnormalities, which might suggest an early cardiac dysfunction because of long-term hypertension. The HF component of HRV thought to be for vagal control might be a cardinal marker for predicting cardiac autonomic dysfunction after acute IS. Short-term HRV spectral analysis is a convenient approach for stroke clinicians to assess autonomic function in acute stroke. Long-term follow-up for HRV and clinical outcome relative to LAA and SVO stroke subtypes is warranted, particularly when an abnormal HRV is found at admission.

Abstract

In the era of thrombolytic therapy for hyperacute ischemic stroke, most investigators have focused their attention on the factors influencing mortality and functional outcomes in patients treated with thrombolysis, but very few have focused on these factors among patients not receiving thrombolysis. The aim of this study was to investigate the prognostic factors for mortality in all hyperacute stroke patients with or without thrombolysis. In 2005, we enrolled 101 ischemic stroke patients (43 females, 58 males; mean age, 68 years) who were transported to the emergency department (ED) within 4 hours of symptom onset. The overall in-hospital mortality rate was 17.8% (18/101). According to t test analysis, age (p = 0.034), time interval from neurologist consultation (p < 0.0001) and ED to ward admission (p = 0.001), Glasgow coma scale (GCS) (p = 0.001), National Institutes of Health Stroke Scale (NIHSS) (p < 0.0001) and the sum of major risk factors of cerebrovascular disease (CVD) (p < 0.0001) were significantly different between mortality and survivor groups. Further χ2 test analysis revealed significant differences in the presenting consciousness disturbance (p = 0.001), place of attack (p = 0.04), and referral transportation (p = 0.008) between these groups. In conclusion, old age, delay between neurologist consultation and ward admission, severity of stroke, and multiple risk factors of CVD are significant risk factors for in-hospital mortality. Conversely, being free of initial consciousness disturbance, living in an urban area, and having direct transportation to a stroke center are protective factors in survivors. The concept of “brain attack” should be re-emphasized among ED physicians. The interconnection between stroke centers and emergency medical systems (EMS) should be more tightly built to promote timely management for hyperacute stroke care.

Abstract

The biggest hurdle for early hospital presentation is the narrow therapeutic window after stroke. The aims of our study were to investigate the time lags and the factors causing pre‐hospital and emergency department (ED) delay during acute ischemic stroke attack. Between June 2004 and October 2005, we prospectively studied 129 acute ischemic stroke patients who presented to the ED of the study hospital within 4 hours after symptom onset. Chi‐square testing for trend, uni‐variate and multiple logistic regression analyses was performed to evaluate the factors influencing delays in the ED presentation of acute ischemic stroke patients. The median time from symptom onset to ED arrival was 71 (mean ± SD, 82.7 ± 57.7) minutes. The median times from ED arrival to neurologic consultation, computed tomography scan, electrocardiogram, and laboratory data completion were 10 (11.3±9.9) minutes, 17 (9.6±11.3) minutes, 14 (23.3±55) minutes, and 39 (44.4±24.5) minutes, respectively. Univariate and multiple logistic regression models revealed that age < 65 years, illiteracy and awakening with symptoms were the most significant factors related to a delay in ED presentation. This study indicates that 2 hours of pre‐hospital delay is the cutoff point for thrombolytic therapy. Organization of a stroke team and standardized stroke pathways may help to shorten in‐hospital time consumption. Educational efforts should not only focus on the public, but also on the training of ED physicians and other medical personnel.

Abstract

The aim of this study was to clarify whether the apolipoprotein E gene (APOE) is related to ischemic stroke subtypes in Taiwan's Chinese population. Using the classification of Cerebrovascular Diseases III, 143 patients with lacunar infarction, 114 patients with atherothrombotic infarction, and 112 healthy controls were enrolled. APOE genotype was determined using polymerase chain reaction. Regarding the distribution of APOE genotypes, the frequency of ϵ3/ϵ4 genotypes in lacunar patients was significantly different from that in control subjects, by logistic regression, using ϵ3/ϵ3 as a reference group. There was no significant difference between atherothrombotic patients and the control group in the distribution of APOE genotypes or alleles. The present finding suggests that there is a probable association between ϵ3/ϵ4 genotype and lacunar infarcts, but not atherothrombotic infarcts. This indicates that genetic factors may play a role, at least partially, in lacunar infarction in Taiwan's Chinese population.

Abstract

Successful treatment of cough syncope depends on the correction of various pathogenetic mechanisms among different patients. The valsalva maneuver (VM), which elicits hemodynamic responses mimicking coughs, has potential for investigating the individual pathogenesis of cough syncope. Eighteen consecutive patients suffering from cough-induced syncope were examined. All patients were asked to cough and to perform VM several times under continuous cerebral blood-flow velocity and blood pressure (BP) monitoring by transcranial Doppler and finger plethysmography. Eight patients demonstrated abnormal VM characterized by the absent BP overshoot following the relief of straining. Patients demonstrating abnormal VM had delayed BP recovery after cough (median, 16.4; range, 8.7–25.6 seconds) compared to those demonstrating normal VM (2.6, 1.3–3.8 seconds, p < 0.001). Seven of the 10 patients exhibiting normal BP overshoot during VM had stenotic arterial lesions in the cerebral or coronary circulation, whereas only one of the eight patients demonstrating absent BP overshoot had coronary artery disease (70% vs. 12.5%, p = 0.025). Other clinical profiles, body mass index, frequency of obstructive pulmonary disease and valsalva ratio did not differ between patients featuring normal and absent BP overshoot. In conclusion, the pathogenesis of cough syncope could be different between patients with normal and abnormal VM responses. Patients who had no BP overshoot during VM sustained prolonged hypotension after cough. The VM helps in discriminating among pathogenic mechanisms and guiding investigation and treatment for cough syncope patients.

Abstract

Estrogen is involved in neuron plasticity and can promote neuronal survival in stroke. Its actions are mostly exerted via estrogen receptor alpha (ERα). Previous animal studies have shown that ERα is upregulated by DNA demethylation following ischemic injury. This study investigated the methylation levels in the ERα promoter in the peripheral blood of ischemic stroke patients.The study included 201 ischemic stroke patients, and 217 age- and sex-comparable healthy controls. The quantitative methylation level in the 14 CpG sites of the ERα promoter was measured by pyrosequencing in each participant. Multivariate regression model was used to adjust for stroke traditional risk factors. Stroke subtypes and sex-specific analysis were also conducted.The results demonstrated that the stroke cases had a lower ERα methylation level than controls in all 14 CpG sites, and site 13 and site 14 had significant adjusted p-values of 0.035 and 0.026, respectively. Stroke subtypes analysis showed that large-artery atherosclerosis and cardio-embolic subtypes had significantly lower methylation levels than the healthy controls at CpG site 5, site 9, site 12, site 13 and site 14 with adjusted p = 0.039, 0.009, 0.025, 0.046 and 0.027 respectively. However, the methylation level for the patients with small vessel subtype was not significant. We combined the methylation data from the above five sites for further sex-specific analysis. The results showed that the significant association only existed in women (adjusted p = 0.011), but not in men (adjusted p = 0.300).Female stroke cases have lower ERα methylation levels than those in the controls, especially in large-artery and cardio-embolic stroke subtypes. The study implies that women suffering from ischemic stroke of specific subtype may undergo different protective mechanisms to reduce the brain injury.

Abstract

Neurologic signs and symptoms are common in acute malarial infection. However, after the parasites have been cleared from the blood and patients recover full consciousness, neurologic or psychiatric symptoms may occur or recur within 2 months after the acute illness. This phenomenon is called “postmalaria neurologic syndrome” (PMNS). We present a 50-year-old man who returned from the Republic of Malawi and soon developed Plasmodium falciparum malaria. Cerebral malaria, renal failure, hepatic failure, diffuse intravascular coagulation with thrombocytopenia, and upper gastrointestinal bleeding were noted during the acute stage. He was admitted to the infectious diseases ward and treated for 3 weeks. He was free from clinical general symptoms and parasites in blood smear when discharged. However, 2 weeks after discharge, he began to experience severe headache, dizziness, diplopia, mild hand tremor, unsteady gait, and easy falling. When readmitted to the neurologic ward, he presented with irritability, delirium, visual hallucination, and strange behavior. Neurologic examination was normal except for mild general weakness and evident truncal ataxia when walking. Brain magnetic resonance imaging revealed no structural lesions, and electroencephalography showed diffuse cortical dysfunction. Cerebral spinal fluid profile exhibited cytoalbuminologic dissociation. Brain single photon emission computed tomography showed diffuse cerebral parenchymal disorder. Nerve conduction studies revealed early sensory predominant polyneuropathy. The unsteadiness persisted for the initial 2 weeks of hospitalization until corticosteroid was administered. Intravenous methylprednisolone (80 mg/day) was continued for 3 days, followed by oral prednisolone (45 mg/day). His unsteadiness improved gradually after medication, and he absconded from the hospital on the 9th day of corticosteroid treatment with clear consciousness and free ambulation. The manifestation of PMNS is diverse and may present as an acute confusional state or psychosis, generalized seizure, fine tremors, cerebellar syndromes, postural hypotension, or malarial polyneuritis. Although the neurologic syndrome is primarily self-limited in most cases, corticosteroid may be beneficial in reversing PMNS.

Abstract

Seizures and focal neurologic deficits may be the complications of neurosyphilis, but status epilepticus as a presenting picture of neurosyphilis is rare. We describe a 41-year-old man with an acute onset of expressive dysphasia, followed by persistent seizure state and severe complications of systemic medical problems. An extensive laboratory evaluation confirmed the diagnosis of neurosyphilis and diabetes mellitus. Brain magnetic resonance imaging showed edematous change in the left cingulate gyrus, left temporal lobe, and peri-Rolandic area, which suggested an inflammatory process. Due to varied clinical manifestations of neurosyphilis, we underscore the importance of considering neurosyphilis among the possible causes of status epilepticus and any central nervous system diseases.

Abstract

Although the Blessed Dementia Rating Scale (BDRS), a clinical screening instrument, has been applied extensively, no suitable cut-off values and clinical application have been proposed, particularly in mild cognitive impairment (MCI), the precursor of dementia. The BDRS, Mini Mental State Examination (MMSE), and Clinical Dementia Rating Scale (CDR) were administrated in people aged 65 years and above, who were enrolled from southern Taiwan with multistep stratified random sampling and followed-up for 2 years. All subjects (total number = 3,027), with new onset of MCI (defined as CDR = 0.5) in the first year and dementia (defined as CDR ≥ 1) in the second and third years were subjected to statistical analysis. In distinguishing normal from MCI, except in the literate group aged 65-74 years, MMSE was superior to BDRS, with cut-off values of 1 in both literate groups aged 65-74 years and ≥ 75 years, and 1.5 and 2 in less educated groups aged 65-74 and ≥ 75 years, respectively. In distinguishing MCI from dementia, BDRS had cut-off values of 2.5 in both literate groups aged 65-74 and ≥ 75 years, and 2.5 and 3 in less educated groups aged 65-74 and ≥ 75 years, respectively. These values were better than those for MMSE in all groups. BDRS might be considered as a better tool than MMSE to screen for MCI and dementia in the increasing proportion of literate elderly aged 65-74 years in the aging population.

Abstract

BackgroundEstrogen receptor α (ERα) has been shown to protect against atherosclerosis. Methylation of the ERα gene can reduce ERα expression leading to a higher risk for cardiovascular disease. Recently, microRNAs have been found to regulate DNA methyltransferases (DNMTs) and thus control methylation status in several genes. We first searched for microRNAs involved in DNMT-associated DNA methylation in the ERα gene. We also tested whether statin and a traditional Chinese medicine (San-Huang-Xie-Xin-Tang, SHXXT) could exert a therapeutic effect on microRNA, DNMT and ERα methylation.Methodology/principal findingsThe ERα expression was decreased and ERα methylation was increased in LPS-treated human aortic smooth muscle cells (HASMCs) and the aorta from rats under a high-fat diet. MicroRNA-152 was found to be down regulated in the LPS-treated HASMCs. We validated that microRNA-152 can knock down DNMT1 in HASMCs leading to hypermethylation of the ERα gene. Statin had no effect on microRNA-152, DNMT1 or ERα expression. On the contrary, SHXXT could restore microRNA-152, decrease DNMT1 and increase ERα expression in both cellular and animal studies.Conclusions/significanceThe present study showed that microRNA-152 decreases under the pro-atherosclerotic conditions. The reduced microRNA-152 can lose an inhibitory effect on DNA methyltransferase, which leads to hypermethylation of the ERα gene and a decrease of ERα level. Although statin can not reverse these cascade proatherosclerotic changes, the SHXXT shows a promising effect to inhibit this unwanted signaling pathway.

Abstract

BACKGROUND: Chromosome 9p21 has recently been shown to be a risk region for a broad range of vascular diseases. Since carotid intima-media thickness (IMT) and plaque are independent predictors for vascular diseases, the association between 9p21 and these two phenotypes was investigated. METHODOLOGY/PRINCIPAL FINDINGS: Carotid segment-specific IMT and plaques were obtained in 1083 stroke- and myocardial infarction-free volunteers. We tested the genotypes and haplotypes of key single nucleotide polymorphisms (SNPs) on chromosome 9p21 for the associations with carotid IMT and plaque. Multivariate permutation analyses demonstrated that carriers of the T allele of SNP rs1333040 were significantly associated with thicker common carotid artery (CCA) IMT (p=0.021) and internal carotid artery (ICA) IMT (p=0.033). The risk G allele of SNP rs2383207 was associated with ICA IMT (p=0.007). Carriers of the C allele of SNP rs1333049 were found to be significantly associated with thicker ICA IMT (p=0.010) and the greater risk for the presence of carotid plaque (OR=1.57 for heterozygous carriers; OR=1.75 for homozygous carriers). Haplotype analysis showed a global p value of 0.031 for ICA IMT and 0.115 for the presence of carotid plaque. Comparing with the other haplotypes, the risk TGC haplotype yielded an adjusted p value of 0.011 and 0.017 for thicker ICA IMT and the presence of carotid plaque respectively. Further analyzing the data separated by sex, the results were significant only in men but not in women. CONCLUSIONS: Chromosome 9p21 had a significant association with carotid atherosclerosis, especially ICA IMT. Furthermore, such genetic effect was in a gender-specific manner in the Han Chinese population.

Abstract

Aim: Although a lower level of non-high-density lipoprotein cholesterol (HDL-C) was reported to be inversely associated with spontaneous intracranial hemorrhage (ICH), no enough evidence has verified whether lipid profiles modify hemorrhagic transformation and functional outcomes in patients with acute ischemic treated with thrombolysis. Methods: This multicenter cohort study included 2373 patients with acute ischemic stroke treated with intravenous thrombolysis between December 2004 and December 2016. Of these, 1845 patients were categorized into either the hyperlipidemia or non-hyperlipidemia group. Symptomatic ICH (SICH) rates within 24–36 h of thrombolytic onset and functional outcomes at 30 and 90 days were longitudinally surveyed. Models of predicting hemorrhagic transformation were used to validate our findings. Results: For enrolled 1845 patients, SICH rates were ≥ 2-fold reduced for the hyperlipidemia group by the NINDS (adjusted RR: 0.488 [0.281–0.846], p = 0.0106), the ECASS II (adjusted RR: 0.318 [0.130–0.776], p = 0.0119), and SITS-MOST standards (adjusted RR: 0.214 [0.048–0.957], p = 0.0437). The favorable functional rates between the two groups were not significantly different. Lower levels of LDL-C were showed in robust association with SICH. With a cut-off LDL-C value of < 130 mg/dL, new models are more robust and significant in predicting hemorrhagic transformation within 24–36 h. Conclusions: This study supports the strong association between reduced LDL-C and increased SICH, but not for functional outcomes in patients with acute ischemic stroke treated with intravenous thrombolysis. LDL-C level of < 130 mg/dL is supposed to a candidate marker for predicting SICH within 24–36 h.

Abstract

OBJECTIVES Dabigatran etexilate is a direct thrombin inhibitor that clinicians increasingly prescribe to prevent stroke in patients with non-valvular atrial fibrillation (NVAF). Clinicians also commonly prescribe statins for primary and secondary prevention of cardiovascular diseases. Little is known about the bleeding risk in patients taking a statin and dabigatran together. The aim of this study was to evaluate the safety and persistence of dabigatran after co-medication with statins. MATERIALS AND METHODS We performed a prospective, multicenter registry study of stroke patients with NVAF who initiated dabigatran therapy within 3 months after a clinically evident ischemic cerebrovascular event between 2013 and 2017. The main outcome measure was symptomatic bleeding after 90, 180, and 360 days. RESULTS In total, 652 patients (336 statin users, 316 non-users) were followed for 1 year after dabigatran therapy. Cox multivariate analysis demonstrated that male sex, prior use of aspirin, and concurrent use of an antiarrhythmic drug were associated with a higher risk of bleeding at 360 days. After adjusting time-dependent covariates, statin users had a significantly lower bleeding risk (adjusted hazard ratio: 0.11, P

Abstract

Supplemental Digital Content is available in the text., Background and Purpose: Among patients with a transient ischemic attack or minor ischemic strokes, those with ipsilateral atherosclerotic stenosis of cervicocranial vasculature have the highest risk of recurrent vascular events. Methods: In the double-blind THALES (The Acute Stroke or Transient Ischemic Attack Treated With Ticagrelor and ASA for Prevention of Stroke and Death) trial, we randomized patients with a noncardioembolic, nonsevere ischemic stroke, or high-risk transient ischemic attack to ticagrelor (180 mg loading dose on day 1 followed by 90 mg twice daily for days 2–30) or placebo added to aspirin (300–325 mg on day 1 followed by 75–100 mg daily for days 2–30) within 24 hours of symptom onset. The present paper reports a prespecified analysis in patients with and without ipsilateral, potentially causal atherosclerotic stenosis ≥30% of cervicocranial vasculature. The primary end point was time to the occurrence of stroke or death within 30 days. Results: Of 11 016 randomized patients, 2351 (21.3%) patients had an ipsilateral atherosclerotic stenosis. After 30 days, a primary end point occurred in 92/1136 (8.1%) patients with ipsilateral stenosis randomized to ticagrelor and in 132/1215 (10.9%) randomized to placebo (hazard ratio 0.73 [95% CI, 0.56–0.96], P=0.023) resulting in a number needed to treat of 34 (95% CI, 19–171). In patients without ipsilateral stenosis, the corresponding event rate was 211/4387 (4.8%) and 230/4278 (5.4%), respectively (hazard ratio, 0.89 [95% CI, 0.74–1.08]; P=0.23, Pinteraction=0.245). Severe bleeding occurred in 4 (0.4%) and 3 (0.2%) patients with ipsilateral atherosclerotic stenosis on ticagrelor and on placebo, respectively (P=NS), and in 24 (0.5%) and 4 (0.1%), respectively, in 8665 patients without ipsilateral stenosis (hazard ratio=5.87 [95% CI, 2.04–16.9], P=0.001). Conclusions: In this exploratory analysis comparing ticagrelor added to aspirin to aspirin alone, we found no treatment by ipsilateral atherosclerosis stenosis subgroup interaction but did identify a higher absolute risk and a greater absolute risk reduction of stroke or death at 30 days in patients with ipsilateral atherosclerosis stenosis than in those without. In this easily identified population, ticagrelor added to aspirin provided a clinically meaningful benefit with a number needed to treat of 34 (95% CI, 19–171).

Abstract

Background: Cerebrovascular pathologies and hypertension could play a vital role in Alzheimer disease (AD) progression. However, whether cerebrovascular pathologies and hypertension accelerate the AD progression through an independent or interaction effect is unknown. Objective: To investigate the effect of the interactions of cerebrovascular pathologies and hypertension on AD progression. Method: A retrospective longitudinal study was conducted to compare AD courses in patients with different severities of cerebral White Matter Changes (WMCs) in relation to hypertension. Annual comprehensive psychometrics were performed. WMCs were rated using a rating scale for Age-related WMCs (ARWMC). Results: In total, 278 patients with sporadic AD were enrolled in this study. The mean age of the patients was 76.6 ± 7.4 years, and 166 patients had hypertension. Among AD patients with hypertension, those with deterioration in clinical dementia rating-sum of box (CDR-SB) and CDR had significantly severe baseline ARWMC scales in total (CDR-SB: 5.8 vs. 3.6, adjusted P = 0.04; CDR: 6.4 vs. 4.4, adjusted P = 0.04) and frontal area (CDR-SB: 2.4 vs. 1.2, adjusted P = 0.01; CDR: 2.4 vs. 1.7, adjusted P < 0.01) compared with those with no deterioration in psychometrics after adjustment for confounders. By contrast, among AD patients without hypertension, no significant differences in ARWMC scales were observed between patients with and without deterioration. Conclusion: The effect of cerebrovascular pathologies on AD progression between those with and without hypertension might differ. An interaction but not independent effect of hypertension and WMCs on the progression of AD is possible.

Abstract

Cardiovascular fitness exerts directly beneficial effects on functional and cognitive outcomes in patients of chronic stroke. However, the effect of early rehabilitation on cardiovascular function has not yet been thoroughly examined. We tested whether complementary rehabilitation program could influence cardiovascular fitness in an early stage of stroke patients. The associations for post-acute stroke functional recovery with cardiovascular fitness were explored. Thirty-seven patients with mean poststroke interval of 8.6 ± 3.8 days underwent inpatient rehabilitation of 22.8 ± 3.8 days. Functional outcomes of 15.3 points (17.2%) in functional independence measure improved after rehabilitation program. The therapeutic cardiovascular fitness was determined in ramp exercise test on a cycling ergometer. Peak oxygen uptake (V˙O2peak) significantly increased by 24.8% after early stroke rehabilitation. Multivariate regression analysis was performed to assess for associations of functional improvement with respect to change in V˙O2peak and extremities motor impairment. V˙O2peak gain accounted for more functional recovery than extremities motor improvement (R2 = 0.42). In conclusion, these results suggest that cardiovascular fitness appears to increase after complementary program in early stroke rehabilitation, and better cardiovascular fitness may be associated with greater functional improvement.

Abstract

Background and aims Renal dysfunction is a potent risk factor for cardiovascular diseases, including stroke. This study aimed to evaluate the impact of admission estimated glomerular filtration rate (eGFR) levels on short-term (1-month) and long-term (1-year) mortality in patients with acute ischemic stroke. Methods From the Taiwan Stroke Registry data, we classified ischemic stroke patients, identified from April 2006 to December 2015, into 5 groups by eGFR at admission: ≥ 90, 60–89, 30–59, 15–29, and Results Among 52,732 ischemic stroke patients, 1480 died within one month. The 1-month mortality rate was over 5-fold greater in patients with eGFR Conclusions After acute ischemic stroke, patients with reduced eGFR are at elevated risks of short-term and long-term deaths in a graded relationship.

Abstract

Background: Stroke is one of the leading causes of mortality and neurologic deficits. Management measures to improve neurologic outcomes are in great need. Our previous intervention trial in elderly subjects successfully used salt as a carrier for potassium, demonstrating a 41% reduction in cardiovascular mortality by switching to potassium-enriched salt. Dietary magnesium has been associated with lowered diabetes and/or stroke risk in humans and with neuroprotection in animals.Objective: Because a large proportion of Taiwanese individuals are in marginal deficiency states for potassium and for magnesium and salt is a good carrier for minerals, it is justifiable to study whether further enriching salt with magnesium at an amount near the Dietary Reference Intake (DRI) amount may provide additional benefit for stroke recovery.Design: This was a double-blind, randomized controlled trial comprising 291 discharged stroke patients with modified Rankin scale (mRS) ≤4. There were 3 arms: 1) regular salt (Na salt) (n = 99), 2) potassium-enriched salt (K salt) (n = 97), and 3) potassium- and magnesium-enriched salt (K/Mg salt) (n = 95). The NIH Stroke Scale (NIHSS), Barthel Index (BI), and mRS were evaluated at discharge, at 3 mo, and at 6 mo. A good neurologic performance was defined by NIHSS = 0, BI = 100, and mRS ≤1.Results: After the 6-mo intervention, the proportion of patients with good neurologic performance increased in a greater magnitude in the K/Mg salt group than in the K salt group and the Na salt group, in that order. The K/Mg salt group had a significantly increased OR (2.25; 95% CI: 1.09, 4.67) of achieving good neurologic performance compared with the Na salt group. But the effect of K salt alone (OR: 1.58; 95% CI: 0.77, 3.22) was not significant.Conclusions: This study suggests that providing the DRI amount of magnesium and potassium together long term is beneficial for stroke patient recovery from neurologic deficits. This trial was registered at clinicaltrials.gov as NCT02910427.

Abstract

We investigated the impact of serum cholesterol levels on 30-day mortality after ischemic stroke in dialysis patients.From the Taiwan Stroke Registry data, we identified 46,770 ischemic stroke cases, including 1101 dialysis patients and 45,669 nondialysis patients from 2006 to 2013.Overall, the 30-day mortality was 1.46-fold greater in the dialysis group than in the nondialysis group (1.75 versus 1.20 per 1000 person-days). The mortality rates were 1.64, .62, 2.82, and 2.23 per 1000 person-days in dialysis patients with serum total cholesterol levels of 120 mg/dL, 120-159 mg/dL, 160-199 mg/dL, and ≥200 mg/dL, respectively. Compared to dialysis patients with serum total cholesterol levels of 120-159 mg/dL, the corresponding adjusted hazard ratios of mortality were 4.20 (95% confidence interval [CI] = 1.01-17.4), 8.06 (95% CI = 2.02-32.2), and 6.89 (95% CI = 1.59-29.8) for those with cholesterol levels of 120 mg/dL, 160-199 mg/dL, and ≥200 mg/dL, respectively.Dialysis patients with serum total cholesterol levels of ≥160 mg/dL or 120 mg/dL on admission are at an elevated hazard of 30-day mortality after ischemic stroke.

Abstract

Background\ud \ud Few studies have assessed regional variation in the organisation of stroke services, particularly health care resourcing, presence of protocols and discharge planning. Our aim was to compare stroke care organisation within middle- (MIC) and high-income country (HIC) hospitals participating in the Head Position in Stroke Trial (HeadPoST).\ud \ud Methods\ud \ud HeadPoST is an on-going international multicenter crossover cluster-randomized trial of ‘sitting-up’ versus ‘lying-flat’ head positioning in acute stroke. As part of the start-up phase, one stroke care organisation questionnaire was completed at each hospital. The World Bank gross national income per capita criteria were used for classification.\ud \ud Results\ud \ud 94 hospitals from 9 countries completed the questionnaire, 51 corresponding to MIC and 43 to HIC. Most participating hospitals had a dedicated stroke care unit/ward, with access to diagnostic services and expert stroke physicians, and offering intravenous thrombolysis. There was no difference for the presence of a dedicated multidisciplinary stroke team, although greater access to a broad spectrum of rehabilitation therapists in HIC compared to MIC hospitals was observed. Significantly more patients arrived within a 4-h window of symptoms onset in HIC hospitals (41 vs. 13%; P < 0.001), and a significantly higher proportion of acute ischemic stroke patients received intravenous thrombolysis (10 vs. 5%; P = 0.002) compared to MIC hospitals.\ud \ud Conclusions\ud \ud Although all hospitals provided advanced care for people with stroke, differences were found in stroke care organisation and treatment. Future multilevel analyses aims to determine the influence of specific organisational factors on patient outcomes.

Made available in DSpace on 2019-10-04T12:41:37Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-07-02 National Health and Medical Research Council of Australia Background-The uptake of proven stroke treatments varies widely. We aimed to determine the association of evidence-based processes of care for acute ischemic stroke (AIS) and clinical outcome of patients who participated in the HEADPOST (Head Positioning in Acute Stroke Trial), a multicenter cluster crossover trial of lying flat versus sitting up, head positioning in acute stroke. Methods and Results-Use of 8 AIS processes of care were considered: reperfusion therapy in eligible patients; acute stroke unit care; antihypertensive, antiplatelet, statin, and anticoagulation for atrial fibrillation; dysphagia assessment; and physiotherapist review. Hierarchical, mixed, logistic regression models were performed to determine associations with good outcome (modified Rankin Scale scores 0-2) at 90 days, adjusted for patient and hospital variables. Among 9485 patients with AIS, implementation of all processes of care in eligible patients, or defect-free care, was associated with improved outcome (odds ratio, 1.40; 95% CI, 1.18-1.65) and better survival (odds ratio, 2.23; 95% CI, 1.62-3.09). Defect-free stroke care was also significantly associated with excellent outcome (modified Rankin Scale score 0-1) (odds ratio, 1.22; 95% CI, 1.04-1.43). No hospital characteristic was independently predictive of outcome. Only 1445 (15%) of eligible patients with AIS received all processes of care, with significant regional variations in overall and individual rates. Conclusions-Use of evidence-based care is associated with improved clinical outcome in AIS. Strategies are required to address regional variation in the use of proven AIS treatments.

Abstract

Peripheral artery disease (PAD) is a manifestation of systemic atherosclerosis and conveys a significant health burden globally. Critical limb ischaemia encompasses the most severe consequence of PAD. Our previous studies indicate that microRNA let‐7g prevents atherosclerosis and improves endothelial functions. This study aimed to investigate whether and how let‐7g therapy may improve blood flow to ischaemic limbs. The present study shows that let‐7g has multiple pro‐angiogenic effects on mouse ischaemic limb model and could be a potential therapeutic agent for PAD. Mice receiving intramuscular injection of let‐7g had more neovascularization, better local perfusion and increased recruitment of endothelial progenitor cells after hindlimb ischaemia. The therapeutic effects of let‐7g's on angiogenesis are mediated by multiple regulatory machinery. First, let‐7g increased expression of vascular endothelial growth factor‐A (VEGF‐A) and VEGF receptor‐2 (VEGFR‐2) through targeting their upstream regulators HIF‐3α and TP53. In addition, let‐7g affected the splicing factor SC35 which subsequently enhanced the alternative splicing of VEGF‐A from the anti‐angiogenic isoform VEGF‐A165b towards the pro‐angiogenic isoform VEGF‐A164a. The pleiotropic effects of let‐7g on angiogenesis imply that let‐7g may possess a therapeutic potential in ischaemic diseases.

Abstract

To determine the clinical implications of hemorrhagic transformation (HT) after thrombolysis, 241 eligible patients receiving alteplase for acute ischemic stroke were studied. HT was classified, according to the European Cooperative Acute Stroke Study criteria, as hemorrhagic infarction (HI) or parenchymal hemorrhage (PH). Symptomatic intracranial hemorrhage (SICH) was defined according to the National Institute of Neurological Disorders and Stroke study. A novel classification, clinically significant intracranial hemorrhage (CSICH) was defined as HTs associated with an unfavorable clinical outcome (modified Rankin Scale 5-6) at 3 months. For all subtypes of HT, we found that patients receiving alteplase were more often in the standard-dose group (0.90 ± 0.02 mg/kg) than in the lower dose group (0.72 ± 0.07 mg/kg). PH and SICH were related to an unfavorable clinical outcome, while HI was not. There was a positive trend between age and CSICH in patients receiving the standard dose (P = 0.0101), and between alteplase dose and CSICH in patients ≥70 years old (P = 0.0228). All PHs (including asymptomatic PHs) and symptomatic HIs have been found to be associated with unfavorable outcome, and for this reason defined as CSICH. Independent predictors of CSICH were age ≥70 years and the standard dose of alteplase. Further studies of thrombolysis for ischemic stroke with different doses of alteplase are warranted.

Given its effectiveness and safety profile, the calcium channel blocker amlodipine is among the most frequently prescribed antihypertensive drugs. This analysis was conducted to determine the costs and quality-adjusted life years (QALYs) associated with the use of amlodipine and valsartan, an angiotensin II receptor blocker, in preventing stroke and MI in Taiwanese hypertensive patients. A state transition (Markov) model was developed to compare the 5-year costs and QALYs for amlodipine and valsartan. Effectiveness data were based on the NAGOYA HEART Study, local studies, and a published meta-analysis. Utility data and costs of MI and stroke were retrieved from the published literature. Medical costs were based on the literature and inflated to 2011 prices; drug costs were based on National Health Insurance prices in 2014. A 3% discount rate was used for costs and QALYs and a third-party payer perspective adopted. One-way sensitivity and scenario analyses were conducted. Compared with valsartan, amlodipine was associated with cost savings of New Taiwan Dollars (NTD) 2,251 per patient per year: costs were NTD 4,296 and NTD 6,547 per patient per year for amlodipine and valsartan users, respectively. Fewer cardiovascular events were reported in patients receiving amlodipine versus valsartan (342 vs 413 per 10,000 patients over 5 years, respectively). Amlodipine had a net gain of 58 QALYs versus valsartan per 10,000 patients over 5 years. Sensitivity analyses showed that the discount rate and cohort age had a larger effect on total cost and cost difference than on QALYs. However, amlodipine results were more favorable than valsartan irrespective of discount rate or cohort age. When administered to Taiwanese patients for hypertension control, amlodipine was associated with lower cost and more QALYs compared with valsartan due to a lower risk of stroke and MI events.

Abstract

Case-control studies have shown that noxious thermal stimulation (TS) can improve arm function in patients with stroke. However, the neural mechanisms underlying this improvement are largely unknown. We explored functional neural activation due to noxious and innocuous TS intervention applied to the paretic arm of patients with stroke. Sixteen participants with unilateral cortical infarctions were allocated to one of two groups: noxious TS (8 patients; temperature combination: hot pain 46°C to 47°C, cold pain 7°C–8°C) or innocuous TS (n = 8; temperature combination: hot 40°C–41°C, cold 20°C–21°C). All subjects underwent fMRI scanning before and after 30 min TS intervention and performed a finger tapping task with the affected hand. Immediate brain activation effects were assessed according to thermal type (noxious vs. innocuous TS) and time (pre-TS vs post-TS). Regions activated by noxious TS relative to innocuous TS (P

Abstract

Background and purpose The optimal dose of alteplase for acute ischemic stroke among geriatric patients is unclear. We aimed to assess the efficacy and safety of a low-dose (0.6 mg/kg) and standard-dose (0.9 mg/kg) alteplase for varying severity of Asian geriatric stroke patients. Methods The favorable functional outcome on day 90 after stroke onset, and the symptomatic intracranial hemorrhage (SICH) rate following 24–36 h of intravenous alteplase were measured. The baseline NIHSS of 4–8, 9–13, ≥14 were defined as mild, moderate, and high severity, respectively. Results Totally, 249 geriatric patients treated with low-dose (n = 108) and standard-dose (n = 141) alteplase. Compared to standard-dose alteplase, low-dose alteplase had decrease in favorable functional outcome (22.2% versus 34.8%), and no difference in SICH rates was observed. For mild severity patients, the mortality was significantly increased with standard-dose alteplase (the NNT/NNH = 22.9/8.0 for mild severity, the NNT/ NNH = 15.0/14.7 for moderate severity, and the NNT/NNH = 13.5/19.6 for high severity). Conclusions Standard-dose and low-dose alteplase were comparable in reducing major disability, but low-dose alteplase for mild stroke showed much reduced mortality on day 90 for octogenarians.

Abstract

Endothelial senescence leads to cell dysfunction, which in turn eventually results in cardiovascular disease. Identifying factors that regulate endothelial senescence may provide insight into the pathogenesis of aging. Insulin-like growth factor (IGF) signaling has a significant role in the physiology of endothelial cells (ECs). Overactivation of IGF signaling has been implicated in promoting the aging process. Lectin‑like oxidized low‑density lipoprotein (oxLDL) receptor‑1 (LOX‑1) is a scavenger receptor that mediates the internalization of oxLDL into cells. Previous studies by our group have indicated that microRNA let‑7g exerts an anti‑aging effect on ECs and also suppresses LOX-1 expression. Since LOX‑1 also induces the aging process, the present study we explored whether let‑7g still exerts an anti‑aging effect on ECs when LOX‑1 is suppressed. Angiotensin II (Ang II) was used to induce senescence in ECs. It was revealed that Ang II significantly increased the expression of aging markers, including β‑galactosidase, LOX‑1, IGF1 and its receptor IGF1R. On the contrary, Ang II decreased the expression of the anti‑aging gene sirtuin 1 (SIRT1). When LOX‑1 was knocked down by small interfering RNA, let‑7g still dose‑dependently decreased the expression of β‑galactosidase (β‑gal), LOX‑1, IGF1 and IGF1R, and SIRT1 was still upregulated. Using senescence‑associated β‑gal staining, it was confirmed that let‑7g exerts a LOX‑1‑independent anti‑aging effect on ECs. In conclusion, the present study demonstrated that let‑7g has an anti‑aging effect regardless of the presence or absence of LOX-1.

Abstract

Poorly controlled blood glucose was reported to cause deterioration of acute ischemic stroke. In this study, we investigated whether an elevated admission serum glucose level in the 3-h time window of intravenous thrombolysis for acute ischemic stroke determined poor functional outcomes among Chinese population.This was a prospective cohort study. From December 1, 2004 to December 31, 2016, a total of 2370 patients were enrolled and categorized into two cohorts by blood glucose levels of ≥200 and200 mg/dl in the 3 h after stroke onset. The primary objective was to determine whether admission hyperglycemia increased major disability and death at 30 and 90 days, which was defined by a modified Rankin Scale of 3-6. The secondary objective was to determine whether admission hyperglycemia increased the symptomatic intracranial hemorrhage (SICH) at 90 days. The number needed to harm (NNH) and patient expected event rate (PEER) were evaluated for both the primary and secondary objectives.The primary outcome occurred in 216 of 305 patients (70.8%) in the blood glucose ≥200 mg/dl cohort and in 951 of 1587 patients (59.9%) in the blood glucose200 mg/dl cohort at 30 days, and in 191 of 287 patients (66.6%) in the blood glucose ≥200 mg/dl cohort and in 827 of 1517 patients (54.5%) in the blood glucose200 mg/dl cohort at 90 days. Patients with admission hyperglycemia had significantly increased major disability and death at 30 (adjusted relative risk (RR): 1.194 [1.073-1.329], p = 0.0012) and 90 days (adjusted RR: 1.203 [1.079-1.340], p = 0.0008). Admission hyperglycemia increased the risk of the occurrence of SICH by nearly 2-fold (adjusted RR: 1.891 [0.977-3.657], p = 0.0585 with the SITS-MOST criteria and adjusted RR: 1.884 [1.138-3.121], p = 0.0139 with the NINDS criteria). NNH values of admission hyperglycemia in major disability and death at 30 and 90 days were 9 and 10, and NNH values of SICH by the SITS-MOST NINDS criteria were 44 and 34, respectively.The study evidenced the association and temporal relationship of admission hyperglycemia causing deterioration of functional outcomes and increased SICH among Chinese population with acute ischemic stroke treated with intravenous thrombolysis.

Abstract

Background/Aim Cerebral white matter changes (WMC) are commonly observed in magnetic resonance imaging (MRI) scans of elderly people. Information about the prevalence of WMC is limited, and little is known about site-specific risk factors for the subcortical and periventricular regions in patients with ischaemic stroke. The study aims to analyse the prevalence and severity of WMC and investigate the risk factors of periventricular WMC (PVWMC) and deep WMC (DWMC) separately in patients with ischaemic stroke. Methods The data were collected between January and December 2013 from a medical centre in southern Taiwan. Every patient underwent a cerebral MRI scan, and WMC was separately rated as PVWMC and DWMC by using the modified Fazekas scale. Results In total, 527 patients who had experienced ischaemic stroke were included. The mean age of the patients was 67.0 ± 12.5 years (range: 31–94) and 62% of them were men. The mean age was significantly different among the four grades of severity in both the PVWMC (P < 0.001) and DWMC (P < 0.001) groups after adjustments for sex and vascular risk factors. Hypertension was independently correlated with severity of DWMC (P = 0.032) but not with PVWMC (P = 0.222). In multiple logistic regressions model, hypertension was a significant independent indicator of DWMC (odds ratio = 4.30; 95% confidence interval = 1.70–10.89). Conclusion Our results suggest a region-specific pathogenesis of cerebral white matter in Asian patients with ischaemic stroke that may differ from those in the general population.

Abstract

Background: Patients with minor acute ischemic stroke or transient ischemic attack are at high risk for subsequent stroke, and more potent antiplatelet therapy in the acute setting is needed. However, the potential benefit of more intense antiplatelet therapy must be assessed in relation to the risk for major bleeding. The SOCRATES trial (Acute Stroke or Transient Ischemic Attack Treated With Aspirin or Ticagrelor and Patient Outcomes) was the first trial with ticagrelor in patients with acute ischemic stroke or transient ischemic attack in which the efficacy and safety of ticagrelor were compared with those of aspirin. The main safety objective was assessment of PLATO (Platelet Inhibition and Patient Outcomes)–defined major bleeds on treatment, with special focus on intracranial hemorrhage (ICrH). Methods: An independent adjudication committee blinded to study treatment classified bleeds according to the PLATO, TIMI (Thrombolysis in Myocardial Infarction), and GUSTO (Global Use of Strategies to Open Occluded Coronary Arteries) definitions. The definitions of ICrH and major bleeding excluded cerebral microbleeds and asymptomatic hemorrhagic transformations of cerebral infarctions so that the definitions better discriminated important events in the acute stroke population. Results: A total of 13 130 of 13 199 randomized patients received at least 1 dose of study drug and were included in the safety analysis set. PLATO major bleeds occurred in 31 patients (0.5%) on ticagrelor and 38 patients (0.6%) on aspirin (hazard ratio, 0.83; 95% confidence interval, 0.52–1.34). The most common locations of major bleeds were intracranial and gastrointestinal. ICrH was reported in 12 patients (0.2%) on ticagrelor and 18 patients (0.3%) on aspirin. Thirteen of all 30 ICrHs (4 on ticagrelor and 9 on aspirin) were hemorrhagic strokes, and 4 (2 in each group) were symptomatic hemorrhagic transformations of brain infarctions. The ICrHs were spontaneous in 6 and 13, traumatic in 3 and 3, and procedural in 3 and 2 patients on ticagrelor and aspirin, respectively. In total, 9 fatal bleeds occurred on ticagrelor and 4 on aspirin. The composite of ICrH or fatal bleeding included 15 patients on ticagrelor and 18 on aspirin. Independently of bleeding classification, PLATO, TIMI, or GUSTO, the relative difference between treatments for major/severe bleeds was similar. Nonmajor bleeds were more common on ticagrelor. Conclusions: Antiplatelet therapy with ticagrelor in patients with acute ischemic stroke or transient ischemic attack showed a bleeding profile similar to that of aspirin for major bleeds. There were few ICrHs. Clinical Trial Registration: URL: http://www.clinicaltrials.gov . Unique identifier: NCT01994720.

Abstract

The early identification of patients with large hemisphere infarctions (LHIs) at risk of fatal brain edema may result in better outcomes. A quantitative model using parameters obtained at admission may be a predictor of in-hospital mortality from LHI. This prospective study enrolled all patients with LHI involving >50% of the middle cerebral artery (MCA) admitted to our neurological intensive care unit within 48 hours of symptom onset. Early clinical and radiographic parameters and the baseline CHADS2 score (congestive heart failure, hypertension, age ≥ 75 years, diabetes mellitus, stroke [double weight]) were analyzed regarding their ability to predict patient outcomes. Seventy-seven patients with LHIs were identified, 33 (42.9%) with complete MCA infarction (CMCA), and 44 (57.1%) with incomplete MCA infarction (IMCA). The predictors of CMCA score included: >1/3 early hypodensity in computed tomography findings, hyperdense MCA sign, brain edema, initial National Institutes of Health Stroke Scale (NIHSS) score ≥17, and stroke in progression during the 1st 5 days of admission. The cutoff CMCA score was 2, with a sensitivity of 81.8% and specificity of 70.5%. Mortality score 1, used for predicting in-hospital mortality from LHI, included CMCA and CHADS2 scores ≥4 (sensitivity 100.0%, specificity 57.4%), and mortality score 2 included CMCA and CHADS2 scores ≥4, and NIHSS score ≥26, during the 1st 5 days (sensitivity 100.0%, specificity 91.7%). Patients qualifying for a mortality score of 2 were at high-risk of in-hospital mortality from LHI. These findings may aid in identifying patients who may benefit from invasive therapeutic strategies, and in better describing the characteristics of those at risk of mortality.

Abstract

The endothelial transient receptor potential cation channel subfamily V member 4 (TRPV4) plays a crucial role in vascular remodeling; however, TRPV4-mediated angiogenesis after ischemic neuronal death as a neurorestorative strategy has not yet been thoroughly examined. In this study, we first tested whether TRPV4 activation can improve functional recovery in rats subjected to transient brain ischemia. The possible mechanisms for TRPV4 activation-promoted functional recovery were explored. A TRPV4 agonist, 4α-phorbol 12,13-didecanoate (4α-PDD), was intravenously injected via the tail vein at 6 h and 1, 2, 3, 4 days after ischemic stroke. The treatment reduced infarct volume by almost 50% (14.7 ± 3.7 vs. 29.2 ± 6.2%; p

Abstract

Background and Purpose: There is limited evidence on head positioning in acute ischemic stroke (AIS) or intracerebral hemorrhage (ICH). Potential benefits for lying flat (0°) include improved collateral blood flow in AIS and for head up (30°) reduced cerebral oedema in ICH. The Head Positioning in Stroke Trial (HeadPoST) aims to provide reliable evidence on the optimum head position in acute stroke. Methods: HeadPoST is a prospective, cluster randomised, crossover, blinded outcome assessed, clinical trial with consecutive patient recruitment who were positioned within 24 hours of admission. Hospitals were randomised to service organisation to compare lying flat vs. sitting up (≥30°) head positioning of stroke patients. An innovative centralized remote monitoring system was used to assess data quality across participating countries. Results: Over a 30 month study period, 10,000+ patients were recruited across 114 hospitals in 9 countries. A web-based monitoring system provided alerts for cross-over time points and achievement of cluster balance. Centralised reports included serious adverse events, protocol deviations, forms completion, data queries, entry delays and data validation, which were distributed to regional co-ordinating centres for action. Details of these procedures are outlined. Conclusions: Reliable, complete, and high quality data were required for this pragmatic international nursing care clinical trial, which used a novel cluster cross-over design.

Abstract

BACKGROUND\ud The role of supine positioning after acute stroke in improving cerebral blood flow and the countervailing risk of aspiration pneumonia have led to variation in head positioning in clinical practice. We wanted to determine whether outcomes in patients with acute ischemic stroke could be improved by positioning the patient to be lying flat (i.e., fully supine with the back horizontal and the face upwards) during treatment to increase cerebral perfusion.\ud METHODS\ud In a pragmatic, cluster-randomized, crossover trial conducted in nine countries, we assigned 11,093 patients with acute stroke (85% of the strokes were ischemic) to receive care in either a lying-flat position or a sitting-up position with the head elevated to at least 30 degrees, according to the randomization assignment of the hospital to which they were admitted; the designated position was initiated soon after hospital admission and was maintained for 24 hours. The primary outcome was degree of disability at 90 days, as assessed with the use of the modified Rankin scale (scores range from 0 to 6, with higher scores indicating greater disability and a score of 6 indicating death).\ud RESULTS\ud The median interval between the onset of stroke symptoms and the initiation of the assigned position was 14 hours (interquartile range, 5 to 35). Patients in the lying-flat group were less likely than patients in the sitting-up group to maintain the position for 24 hours (87% vs. 95%, P

Abstract

Rationale It is not uncommon for patients with ischemic stroke to have peripheral arterial disease (PAD). Patients with polyvascular diseases carry greater burden of atherosclerosis and higher risks of developing vascular events and death. More effective regimens, such as dual antiplatelet agents, may be more effective for controlling progression of atherosclerosis in secondary prevention. Aim This study aims to evaluate whether cilostazol plus aspirin is more efficacious than aspirin alone for preventing progression of atherosclerosis in patients with ischemic stroke or transient ischemic attack (TIA) who also have peripheral arterial disease. Design The Safety and Efficacy of Cilostazol in Ischemic Stroke Patients with Peripheral Arterial Disease (SPAD) study is a randomized double-blinded placebo-controlled trial. Patients with previous ischemic stroke or TIA who had been taking aspirin (100 mg per day), aged 50 years or older, with PAD in the lower limbs based on ankle-brachial index (ABI) Study outcomes Patients will be evaluated at 1, 3, 6, 9 and 12 months after randomization. The primary endpoint is difference in change in ABI between groups. The secondary and tertiary endpoints are the difference between groups in change in carotid intima-media thickness (IMT) and incidence rate of major cardiovascular events, including recurrent stroke, myocardial infarction, unstable angina, other vascular events, and death; and the safety measures, including major bleeding events, hemorrhagic stroke and death of any cause. Conclusion The SPAD trial is the first study to evaluate the safety and efficacy of dual antiplatelet agents, aspirin plus cilostazol, in comparison with aspirin alone in patients with both ischemic stroke or TIA and PAD. Results from this trial will provide important information on the merit of adding cilostazol to aspirin for slowing down progression of atherosclerosis in patients with ischemic stroke and PAD.
