Background
Poststroke balance impairment adversely affects stroke outcomes and addressing the impairment is expected to constitute an important focus of neurorehabilitation.Aims
To examine the prevalence and factors associated with balance impairment after stroke.Methods
Ninety-five stroke survivors undergoing neurorehabilitation at 2 government hospitals in Northern Nigeria participated in this cross-sectional study. Berg Balance Scale (BBS) was used to assess the presence of balance impairment (BBS score of 0-20). Prevalence of balance impairment was presented as frequency and percentage while demographic and stroke-related determinants of balance impairments were identified using logistic regression analysis.Results
Thirty-five (36.8%) stroke survivors had balance impairment, and age, gender, and poststroke duration were statistically significant determinants. Stroke survivors aged less than 40 years (odds ratio [OR]?=?.14 [confidence interval [CI]?=?.20-.94]) and 40-59 years (OR?=?.23 [CI?=?.06-.81]) had a lower likelihood of having balance impairment compared to stroke survivors aged 60 years and above. Similarly, males had a lower likelihood of having balance impairment (OR?=?1.60 [CI?=?.05-.55]) compared to females while those in the acute/subacute phase of stroke had a 7-fold likelihood of having balance impairment (OR?=?7.74 [CI?=?2.63-22.79]) compared to those with chronic stroke.Conclusions
Poststroke balance impairment appears to be significantly influenced by stroke survivors’ age, gender, and poststroke duration. Hence, these variables should be considered when planning rehabilitation strategies for improving balance after stroke. 相似文献2.

Background
To validate iScore and PLAN score in acute anterior circulation large vessel occlusion stroke patients undergoing thrombectomy.Methods
iScore and PLAN score were calculated for consecutive acute ischemic stroke undergoing thrombectomy were included and death at 1 month and death at 3 months were recorded. The area under the receiver operating characteristic curve was used to assess the discrimination ability of the scales for death.Results
Two hundred and twenty-nine patients were included, 25.3% (58 of 229) of patient died at 1 month after thrombectomy and 25.8% (59 of 229) of them died at 3 months after thrombectomy. The receiver operator curve analysis found that iScore (area under the curve [AUC] = .76, 95% confidence interval [CI] .69-.83) was numerically better than PLAN score (AUC?=?.73, 95% CI .66-.81) for predicting death at day 90. The cut-off for iScore is 193, with sensitivity 64%, specificity 79%, positive predictive value 75% and negative predictive value 69%.Conclusions
The iScore scale is a valid predictive tool for death in anterior circulation large vessel occlusions undergoing thrombectomy. 相似文献3.

Background
Several studies have shown that high level of plasma C-reactive protein (CRP) is associated with stroke outcomes and future vascular events, and a decrease in serum triiodothyronine (T3) was reported to be associated with stroke severity and poor prognosis.Objective
The goal of this study is to evaluate CRP and T3 as independent predictors of poor functional and cognitive outcomes in patients with acute ischemic stroke at hospital discharge.Methods
This study evaluated 120 patients who were admitted to the Clinical Hospital of Neurology and Psychiatry Brasov, between July 2016 and January 2017. The patients were evaluated for clinical stroke severity (National Institutes of Health Stroke Scale) and serum CRP and total T3 were evaluated on admission. Functional outcome and cognitive outcome were evaluated at discharge.Results
The severity of NIHHS scores were associated with higher CRP levels (β?=?.583, P = .000) and lower T3 concentration (β = ?.185, P?=?.043). Poor cognitive prognosis was associated with CRP levels (β?=?.441, P?=?.000) but not with T3 concentrations (P?=?.142). Poor functional outcome was associated with higher CRP levels (β?=?.457, P?=?.000), but not with T3 concentrations (P?=?.100). Using CRP and T3 as prognostic factors resulted in a probability of 53.5% to predict a poor functional outcome and of 80.42% to predict a poor cognitive outcome in stroke patients at discharge.Conclusions
The study showed that higher CRP and lower T3 levels were associated with stroke severity on admission. Functional outcome is likely secondary to stroke severity but functional outcome at discharge was associated with higher CRP levels and not with T3 concentration. Cognitive outcome was associated with higher CRP levels and not with T3 concentration. 相似文献4.

Background
The treatment of acute ischemic stroke due to large vessel occlusion (LVO) has revolutionized in the last decade. We sought to compile the most relevant literature published about the evolution in treating this disabling and fatal disease.Methods
A literature review of recent studies describing early treatment options like intravenous tissue plasminogen activator to the latest mechanical thrombectomy (MT) techniques was performed. We described in a chronological order the evolution of LVO treatment.Results
Recanalization rates with newer techniques and MT devices approach a 90% of effectiveness. Timely interventions have also resulted in better clinical outcomes with approximately 50% of patient achieving functional independence at 90 days. At least 14 new third generation thrombectomy devices are currently being evaluated in in vitro and clinical studies.Conclusions
The treatment of LVO with MT is feasible and safe. MT is standard of care in treating acute ischemic stroke due to LVO. 相似文献5.

Background
Considerable researches suggest that high level of homocysteine (Hcy) is associated with the risk of ischemic stroke. Ambulatory blood pressure monitoring (ABPM) parameters have also been confirmed associated with cardio-cerebrovascular events. However, the relationship between Hcy and ABPM parameters remains unclear in patients with acute ischemic stroke. In this study, we aim to investigate the association between Hcy level and ABPM parameters in patients with acute ischemic stroke.Methods
We enrolled 60 patients with acute ischemic stroke who received ABPM. We calculated ABPM parameters like morning blood pressure surge (MBPS), ambulatory arterial stiffness index, blood pressure variability, and night dipping patterns.Results
Multivariate logistic regression analysis indicated that patients in the top quartile of Hcy level tended to have a higher level of prewaking and sleep-trough MBPS compared with patients in the lower 3 quartiles after adjusted for age and gender (P?=?.028 and P?=?.030, respectively). When treating Hcy as a continuous variable, the linear regression showed the association between Hcy level and both MBPS parameters remained significant (prewaking MBPS, r?=?.356, P?=?.022; sleep-trough MBPS, r?=?.365, P?=?.017, respectively). However, there is no association between Hcy level and ambulatory arterial stiffness index, blood pressure variability or night dipping patterns (P?=?.635, P?=?.348 and P?=?.127 respectively).Conclusions
There is a relationship between the 2 major cerebrovascular risk factors: MBPS and Hcy. 相似文献6.

Objectives
To describe the neurological manifestations of invasive aspergillosis presenting with a focal neurological deficit compatible with an acute stroke.Materials and Methods
Retrospective analysis of a clinical series of patients between 2011 and 2017 with invasive aspergillosis and neurological symptoms compatible with an acute brain stroke. Clinical and epidemiological data, microbiological results, radiological findings, treatment, and course were recorded.Results
Five patients were selected with a mean age of 55.4years. All patients were immunosuppressed. In 4, systemic infection was unknown. In every case, neurology on call was alerted because of acute focal neurological symptoms. None of the patients received revascularization procedures. Galactomannan antigen was positive in all of the patients and culture was positive in 3. Mortality was 100% despite specific antifungal treatment.Conclusions
Acute stroke can be the first manifestation of disseminated aspergillosis. This form of presentation was frequent in our series and should be suspected in immunocompromised patients with acute neurological deficits. 相似文献7.

Background
Access to reperfusion therapies in patients with large vessel occluding acute ischemic stroke demands process reorganization and optimization. Neurovascular networks are being built up to provide 24/7 endovascular stroke therapy service. In times of an increasingly complex stroke rescue chain little is known about patients’ and their relatives’ treatment awareness.Methods
All patients, who received any kind of acute reperfusion treatment between January and August 2017 in the university hospital Aachen, and their proxies, were included in the survey. Patients were either primarily or secondarily transferred.Results
For all questions regarding stroke treatment patients and their caregivers provided concurring answers. 40% of both patients and caregivers did not understand the treatment that was performed. Finally, patients who perceived on their own that stroke detection was delayed had significantly longer onset to door times than patients who did not have this impression.Conclusions
This study showed that patients’ and proxies’ answers correlated significantly. In case of patients’ unavailability extrapolation of treatment satisfaction from answers by proxies might be permitted. High percentages of patients and caregivers do not understand relevant information, possibly due to limits of communication in an emergency setting or deficits in communication during the hospital stay. More emphasis should be laid on providing further information during the hospital stay. 相似文献8.

Background
Evidence from outside the typical clinical research setting, such as the real-world setting, complements evidence coming from randomized controlled trials. The purpose of this study was to evaluate all available evidence from the real-world observational trials about long-term outcomes of treatment with intravenous (IV) recombinant tissue-type plasminogen activator (rt-PA) compared with not treated with IV rt-PA (non-rt-PA) in patients with acute ischemic stroke.Methods
We searched PubMed and Embase until March 1, 2018 for observational studies reporting matched or adjusted results comparing IV rt-PA versus non-rt-PA in patients with acute ischemic stroke. Outcomes assessed included all-cause mortality, hospital readmission rates, and independence rates. Hazard ratios with 95% confidence intervals were used as a measure of comparing between patients treated with IV rt-PA and non-rt-PA.Results
Six observational trials with 16,399 participants were identified. The use of IV rt-PA in acute ischemic stroke patients was associated with a lower risk of mortality (hazard ratio .61; 95% confidence interval, .52-.70; P < .00001), and there was no heterogeneity across trials. There was no evidence of an effect on hospital readmission rates and independence rates.Conclusions
IV rt-PA is associated with reduced long-term mortality in acute ischemic stroke patients. 相似文献9.

Background
The clinical presentations and outcomes of patients with high-grade stenosis of internal carotid artery (ICA) are highly variable. We investigate the influence of different stroke severity on outcomes of ischemic stroke patients with high-grade stenosis of ipsilateral ICA.Methods
372 acute first-ever ischemic stroke patients with high-grade stenosis (70%-99%) or occlusion of ipsilateral ICA were enrolled and followed up for 5years. Stroke severities of the enrolled patients were grouped according to the Oxfordshire Community Stroke Project classification system as total anterior circulation infarcts (TACI) or non-TACI. Demographic features, vascular risk factors, comorbidities, and outcomes were compared between the 2 groups.Results
A total of 71 patients (19.1%) were presented with TACI. Of laboratory data, the values of white blood cell count and high-sensitivity C-reactive protein were significantly higher in patients with TACI (P?=?.008 and P?=?.003, respectively). Of clinical course, the occurrence of initial impaired conscious, stroke-in-evolution, pneumonia, gastrointestinal bleeding, and urinary tract infection were significantly higher in patients with TACI. The prevalence of dependent functional status was higher in patients with TACI. Multivariate Cox regression revealed that TACI is a significant predictor of 5-year all-cause mortality in first-ever ischemic stroke patients with high-grade stenosis of ipsilateral ICA (HR [hazard ratio] = 3.66, 95% confidence interval = 2.23-6.00, P < .001).Conclusions
TACI is associated with increased risk of 5-year mortality in ischemic stroke patients with high-grade stenosis of ipsilateral ICA. Intensive medical treatment for stroke prevention in patients with severe carotid artery stenosis is warranted. 相似文献10.

Background
To assess whether the type of primary caregiver is a risk factor of the incidence of fracture among older adults who have survived a stroke.Methods
Data from 4282 stroke survivors in the National Health Insurance Service—Senior Cohort (2002-2013) were used in this study. We categorized type of primary caregiver as none, spouse/family caregiver, and formal caregiver. The incidence of fracture within the year postdischarge was used as the outcome variable. These data were subjected to a survival analysis using the Cox proportional hazard model.Results
Of the 4282 stroke survivors, 308 (7.2%) experienced a fracture during the 1-year follow-up period. According to type of primary caregiver, the adjusted hazard ratio (HR) of fracture was lower among those whose caregiver was a spouse (HR?=?.68, 95% confidence interval [CI], .48-.96] and those with a formal caregiver (HR?=?.59, 95% CI, .36-.97) compared to stroke survivors with no caregiver. In particular, those with a family or formal caregiver who were being cared for in nursing facilities were less likely to be associated with fracture than those with no caregiver.Conclusions
The adjusted HR of fracture among stroke survivors was lower among those with primary caregivers compared to those without them. Thus, the government should monitor and allocate the appropriate attention to stroke survivors after discharge in order to ensure that they obtain the needed health care, especially for stroke survivors who are without a primary caregiver. 相似文献11.

Objective
The aim of this prospective cohort study was to assess the incidence and risk factors of delirium following acute ischemic stroke, as well as its effects on functional outcome.Methods
Two hundred and sixty-one patients with acute ischemic stroke were screened for delirium during the first week after admission. Delirium was diagnosed according to the Confusion Assessment Method. If delirium was present, delirium rating scale-revised-98 was used to assess its severity. Neurologic deficits were assessed with the National Institutes of Health Stroke Scale (NIHSS). Brain magnetic resonance imaging assessment quantified the infarction, white matter lesions, and medial temporal lobe atrophy. Functional outcome assessment included the modified Rankin Scale and Lawton Instrumental Activities of Daily Living scale at 3 and 6 months after the index stroke.Results
Thirty-eight (14.6%) patients with acute ischemic stroke developed delirium during the first week of admission. Patients with poststroke delirium (PSD) were older, had higher NIHSS scores on admission, and were more likely to have a previous stroke, an infection, and a left cortical infarct. Furthermore, left cortical infarction, older age, severer neurological deficit and having a previous stroke increased the risk of PSD. PSD was associated with a worse functional outcome.Conclusion
The incidence of delirium was 14.8% in the first week after admission with acute ischemic stroke. Age, having a previous stroke, stroke severity, and left-cortical infarction were independently predictors of PSD. PSD may result in a significantly worse functional outcome. 相似文献12.

Background
We present a single institution registry with the novel feature of 90-day outcome assessments on all hospitalized acute stroke patients, inclusive of every patient with a primary discharge diagnosis of transient ischemic attack (TIA), acute ischemic stroke (AIS), nontraumatic subarachnoid hemorrhage (SAH), and intracerebral hemorrhage (ICH).Methods
Patient data obtained in the HOPES registry include demographics, comorbid diagnoses, medications, health behaviors, laboratory values, imaging studies, vital signs, and outcome measures, most notably the modified Rankin Scale (mRS) at 90days.Results
From May 2016 to December 31, 2017, 1607 patients were enrolled in the HOPES registry. 90-day outcome assessments were captured on 1555 patients (97%): 1096 AIS, 230 ICH, 110 SAH, and 119 TIA patients. Mortality rates and 90-day outcomes were most favorable for TIA patients. Mortality and 90-day disability scores were poorest for patients in the ICH group.Conclusions
The inclusion of 90-day outcomes data will allow HOPES to stand apart among stroke registries as a new standard for stroke outcomes research. The registry will provide the necessary comprehensive data that the field needs as we transition our focus of stroke research to poststroke recovery. 相似文献13.

Background
Debate continues about whether percutaneous closure of patent foramen ovale (PFO) is a better strategy for the treatment of patients with cryptogenic stroke in comparison with medical therapy alone. We performed an updated meta-analysis of 6 randomized controlled trials (RCTs) to assess the effectiveness and safety of percutaneous closure of PFO as secondary prevention for patients with previous cryptogenic stroke compared to medical therapy.Materials and Methods
MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, conference proceedings, and Internet-based resources were retrieved in March 2018 for eligible RCTs. The primary effectiveness outcome was recurrent strokes.Results
Six studies meeting our selection criteria were identified. Among 3560 participants, 1889 patients were assigned to PFO closure and 1671 patients to medical therapy. There were no significant differences among the baseline characteristics. The pooled incidence of recurrent strokes was 1.96% in the PFO closure group and 4.60% in the medical therapy group (Relative risk [RR] .39, 95% confidence interval [CI] .18-.82, P?=?.01). Newly detected atrial fibrillation occurred in 77 of 1844 (4.18%) patients in the PFO closure group and in 12 of 1667 (.72%) patients in the medical therapy group (RR 4.56, 95% CI 2.21-9.41, P <.0001). There was no difference in terms of serious adverse events, total mortality or bleeding between 2 groups.Conclusions
Our updated meta-analysis suggests that in patients with PFO and cryptogenic stroke, the rate of recurrent stroke is significantly reduced with percutaneous closure of PFO compared to the medical therapy. 相似文献14.

Introduction
Immune thrombotic thrombocytopenic purpura (i-TTP), related to acquired ADAMTS-13 dysfunction, can lead to various neurological symptoms including ischemic stroke. To date the clinical, radiological, and biological characteristics of patients having a stroke as the inaugural manifestation of i-TTP are largely unknown.Methods
Probable immune-TTP was defined by a low ADAMTS-13 activity associated with the presence of ADAMTS-13 inhibitors and/or favorable clinicobiological response under immunological treatments. The clinical, radiological, biological data and outcome under treatment are described in a cohort of 17 patients coming from 3 local cases and a literature review.Results
Fourteen of the 17 patients were female and the mean age was 41 years. None of the patients had the classical pentad of TTP. Only 41% had a combination of thrombocythemia and hemolysis. Stroke was multifocal in 35% and included large artery strokes. No adverse event was observed following intravenous thrombolysis. Refractory and relapsing forms were observed in 47%.Discussion
The clinical, radiological, and biological presentation of patients with stroke as the inaugural presentation of i-TTP is heterogeneous. This diagnosis should be discussed in every young adult with ischemic stroke of undetermined source. 相似文献15.

Background
Despite the use of validated prehospital stroke scales, stroke mimics are frequent among patients transported by Emergency Medical Services to the Emergency Department. We aimed to describe the frequency and characteristics of neurological and non-neurological mimics transported to a comprehensive stroke center for acute stroke evaluation.Methods
This was a retrospective analysis of a database consisting of all consecutive patients with suspected stroke transported to the Emergency Department of a comprehensive stroke center during an 18-month period. Hospital charts and neuroimaging were utilized to adjudicate the final diagnosis (acute stroke, stroke mimic, and specific underlying diagnoses).Results
Nine hundred fifty patients were transported with suspected stroke, among whom 405 (42.6%) were stroke mimics (age 66.9 ± 17.1 years; 54% male). Neurological mimics were diagnosed in 223 (55.1%) patients and mimics were non-neurological in 182. The most common neurological diagnoses were seizures (19.7%), migraines (18.8%), and peripheral neuropathies (11.2%). Cardiovascular (14.6%) and psychiatric (11.9%) diagnoses were common non-neurological mimics. Patients with neurological mimics were younger (64.1 ± 17.3 years versus 70.5 ± 16.1 years, P < .001) and had less vascular risk factors than non-neurological mimics. The proportion of non-neurological mimics remained high (38%) despite the use of a prehospital stroke identification scale.Conclusions
Stroke mimics are common among patients transported by Emergency Medical Services to a comprehensive stroke center for suspected stroke, with a considerable proportion being non-neurological in origin. Studies refining triage and transport of suspected acute stroke may be warranted to minimize the number of mimics transported by to a comprehensive stroke center for acute stroke evaluation. 相似文献16.

Goal
Epilepsy is a major complication of stroke. There have been suggestions that patients with cardioembolic stroke are at a greater risk of developing seizures than other stroke subtypes. However, the incidence of atrial fibrillation (AF) and cardioembolic stroke varies considerably across countries, generally higher in Western populations than in Asian populations. This study assessed whether ethnicity affects the association between AF and poststroke seizure (PSS) development. We hypothesized that Royal Melbourne Hospital ([RMH] Melbourne) patients will have significantly higher incidence of AF-related PSS than in the Jinling Hospital (Nanjing) population.Materials and Methods
This was a retrospective, multicenter cohort study including patients with anterior circulation ischemic stroke admitted between 2008 and 2015. Occurrences of PSS were ascertained by reviewing medical records or telephone follow-up. To test the hypothesis of an interaction between ethnicity and AF for PSS occurrence, a logistic regression model with AF and ethnicity together with an ethnicity-by-AF interaction term was used.Findings
Of 782 patients followed-up for seizure development at RMH, 247 (31.6%) patients had AF, of whom 10 (4%) developed PSS. Of 1185 patients followed-up and included at JH, 54 (4.8%) patients with AF, of whom 4 (7.4%) developed PSS. At RMH, no significant association was found between AF and PSS; odds ratio .75, 95% confidence interval .4-1.6, (P?=?.4). At JH, there was a significant association between AF and increased PSS: OR 4.0, 95% CI 1.3-12.1, (P?=?.01), P for interaction?=?.03.Conclusion
Further understanding of genetic risks and environmental differences across ethnic populations and the role in PSS is required. 相似文献17.

Objects
To identify predictors of acute ischemic stroke (AIS) among patients presenting to the Emergency Department (ED) with dizziness, imbalance, or vertigo (DIV) based on demographic and clinical characteristics.Methods
We identified patients admitted to the hospital after presenting to the ED with DIV from the Statewide Planning and Research Cooperative System database of New York from 2010 to 2014. Demographic and clinical characteristics were systematically collected. Multivariable logistic regression was used to determine predictors of a discharge diagnosis of AIS.Results
Among 77,993 patients with DIV, 3857 (4.9%) had a discharge diagnosis of AIS. Admission presentation of imbalance, African-American race, history of hypertension, diabetes mellitus, hypercholesterolemia, tobacco use, atrial fibrillation, and prior AIS due to extracranial artery atherosclerosis were each positively associated with an AIS diagnosis independently. Factors negatively associated with an AIS discharge diagnosis included: admission presentation of vertigo, female sex, age > 81, history of anemia, coronary artery disease, asthma, depressive disorders, and anxiety disorders.Conclusions
Multiple potential positive and negative predictive AIS risk factors were identified. Combining with currently available centrally-caused dizziness prediction tools, these newly identified factors could provide more accurate AIS risk stratifying method for DIV patients. 相似文献18.

Background and Purpose
Acid/base and electrolytes could provide clinically valuable information about cerebral infarct core and penumbra. We evaluated associations between acid/base and electrolyte changes and outcomes in 2 rat models of stroke, permanent, and transient middle cerebral artery occlusion.Methods
Three-month old Sprague-Dawley rats underwent permanent or transient middle cerebral artery occlusion. Pre- and post-middle cerebral artery occlusion venous samples for permanent and transient models provided pH, carbon dioxide, oxygen, glucose, and electrolyte values of ionized calcium, potassium, and sodium. Multiple regression determined predictors of infarct volume from these values, and Kaplan-Meier curve analyzed morality between permanent and transient middle cerebral artery occlusion models.Results
Analysis indicated significant differences in the blood gas and electrolytes between pre- to post-middle cerebral artery occlusion. A decrease in pH and sodium with increases in carbon dioxide, potassium, ionized calcium, and glucose changes were found in both middle cerebral artery occlusion models; while hematocrit and hemoglobin were significant in the transient model. pH and ionized calcium were predictors of infarct volume in the permanent model, as changes in pH and ionized calcium decreased, infarct volume increased.Conclusions
There are acute changes in acid/base balance and electrolytes during stroke in transient and permanent rodent models. Additionally, we found pH and ionized calcium changes predicted stroke volume in the permanent middle cerebral artery occlusion model. These preliminary findings are novel, and warrant further exploration in human conditions. 相似文献20.
