Background and Purpose
The ASA/AHA guidelines recommend a fixed dose of 90 mg of intravenous (IV) recombinant tissue plasminogen activator (rt-PA) for acute stroke patients weighing more than 100 kg. We aimed to determine if body weight >100 kg (and receiving <0.9 mg/kg dose) independently influence patient clinical outcomes following IV rt-PA treatment.Methods
We pooled data from IV rt-PA treatment arms from 3 randomized controlled clinical trials; NINDS IV rt-PA study, Interventional Management of Stroke 3 and ALIAS (part 1 and 2). Baseline characteristic, hospital course and 90-day mRS were compared between patients >100 kg and those ≤100 kg body weight. Multivariate logistic regression model was used to identify the independent effect of >100 kg body weight on favorable 90-day outcome (defined as mRS 0-2), the rate of symptomatic intracranial hemorrhage, and poor 90-day outcome (mRS 4-6).Results
Among 873 patients treated with IV rt-PA, a total of 105 (12%) subjects had body weight >100 kg. Compared with patients having ≤100 kg body weight, the rate of favorable outcome at 90 days was not significantly different among patients with >100 kg body weight (OR: 0.99; 95% CI: 0.91-1.01; p=0.91) , after adjusting for potential confounders. The ordinal analysis did not show any significant shift in the distribution of 90-day mRS score in patients with >100 kg body weight (OR, 0.93; 95% CI, 0.64-1.37; P?=?0.74)Conclusions
There was no reduction in the rate of favorable outcome in patients with acute ischemic stroke with body weight >100 kg who received <0.9 mg/kg dose of IV rt-PA. Our results support the current recommendations in the ASA/AHA guidelines. 相似文献2.

Background
Cancer treatment, specifically surgical intervention, as a possible stroke trigger is understudied.Methods
Using the Nationwide Readmissions Database and validated diagnosis and procedure codes, we identified adults with index admissions for colorectal surgery for colorectal adenocarcinoma (Group A) and compared them to admissions for colorectal surgery for benign conditions (Group B) and hepatobiliary or pancreatic surgery for benign conditions (Group C). Within the colorectal cancer cohort, we further identified patients who underwent open versus laparoscopic surgery. The primary outcome was readmission for ischemic or hemorrhagic stroke up to 1 year. Cumulative risk of ischemic stroke was calculated using risk survival statistics, and hazard ratios (HR) were calculated using adjusted Cox regression.Results
Patients in Group A had higher 3-month readmission rates for ischemic and hemorrhagic strokes than those in Groups B and C. Higher risk of ischemic stroke (HR 1.46, 95% confidence interval [CI] 1.20-1.79) in Group A compared to Group B was eliminated following adjustments for illness severity and vascular risk factors. Comparing types of colorectal surgical intervention for cancer, there was significantly greater risk of ischemic stroke with open versus laparoscopic surgery, despite adjusting for vascular risk factors (HR 1.70, 95% CI 1.15-2.52).Conclusions
We found elevated risk of ischemic stroke up to 1 year following open surgery for colorectal adenocarcinoma compared to laparoscopic. More research is necessary to clarify the underlying surgery-related mechanisms that contribute to elevated risk. 相似文献4.

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5.

Background
Antiplatelet therapy is a cornerstone prevention strategy for secondary ischemic stroke (IS) and transient ischemic attack (TIA). Yet, a proportion of patients who receive antiplatelet therapy experience recurrent ischemic cerebrovascular events. A recent meta-analysis found an increased risk of recurrent stroke in clopidogrel- or aspirin-treated patients with ischemic stroke who had high on-treatment platelet reactivity (HTPR). Few studies have focused specifically on clopidogrel HTPR. Therefore, the aim of this study was to examine the relationship between clopidogrel HTPR and recurrent ischemic events in a population of Danish patients with IS.Methods
We performed a prospective observational study to evaluate the relationship between HTPR defined as platelet reaction units >208 and a composite primary endpoint of recurrent stroke, TIA, acute myocardial infarction (AMI), or vascular death over a 2-year follow-up period.Results
A total of 142 patients were included in the final statistical analysis, but only 3 patients (2.1%) demonstrated clopidogrel HTPR. The median time of on-treatment platelet testing was 75 days. Recurrent IS, TIA, AMI, or vascular death occurred in 14 patients (10%). Of these, 1 new ischemic event (AMI) occurred in a HTPR patient. There was no difference in the frequency of new ischemic events between the HTPR and non-HTPR groups (P = .27); moreover, the number of patients with HTPR was too small for statistical analysis.Conclusions
Clopidogrel HTPR does not seem to be a major contributor to recurrent ischemic events in Danish ischemic stroke patients. 相似文献6.

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7.

Objectives
Many patients admitted with an ischemic stroke or transient ischemic attack (TIA) undergo thrombophilia testing. There is limited evidence to support this practice. We examined the effect of thrombophilia testing on management of patients admitted with an ischemic stroke or TIA.Materials and Methods
In this retrospective observational single-center study, we identified patients who were admitted with stroke or TIA and underwent thrombophilia testing over a 45-month period. We reviewed their electronic medical records to assess whether testing affected clinical management, defined as anticoagulation treatment by the time of discharge due to a positive test result. Secondary endpoints included potential misdiagnosis due to false positive results and cost of testing.Results
Testing was performed in 143 patients with a stroke or TIA. Forty-four patients (31%) had at least 1 positive test result. The most common positive tests were an elevated factor VIII activity (18% of patients tested) and decreased protein S activity (11% of patients tested). Both of these tests are subject to acute phase effects. Testing altered clinical management in only 1 patient (1% of total patients tested). Thirty-three patients (75%) have the potential for carrying a misdiagnosis due to a positive test that was never repeated for confirmation or repeated too soon after the initial positive test. The annual cost of testing was approximately $62,000.Conclusions
Thrombophilia testing in the acute inpatient setting rarely impacted the clinical management of patients admitted with a stroke or TIA. By avoiding thrombophilia testing, both the potential for misdiagnosis and health care costs can be reduced. Therefore, we have discontinued thrombophilia testing in in-patients with a diagnosis of stroke. 相似文献8.

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9.

Background and Purpose
To improve results of acute thrombectomy, the time from stroke onset to efficient recanalization must be minimized. Studies have confirmed the importance of rapid treatment, workflow, and efficient team-based care for acute thrombectomy in large vessel occlusion. This study examined the challenges facing mechanical thrombectomy in the Tama area (population, 4.3 million), a densely populated urban area of Tokyo, Japan, and analyzed retrospective data from the Tama-REgistry of Acute endovascular Thrombectomy.Methods
This study was a retrospective observational study using data from Tama-REgistry of Acute endovascular Thrombectomy, a multicenter registry of mechanical thrombectomy for acute ischemic stroke in the Tama area of Tokyo. The survey covered 396 patients with large vessel occlusion who underwent acute thrombectomy between January 2015 and March 2017. Participating facilities are 12 of the 13 recanalization therapy-capable stroke centers.Results
We analyzed 326 cases for which modified Rankin Scale score at 90days was available, of which 264 cases were directly admitted, and 62 cases were transferred from other stroke centers. Median time from stroke onset to hospital arrival was 111 minutes, and from arrival to efficient recanalization was 135 minutes. Efficient recanalization was achieved in 257 cases (78.8%), symptomatic hemorrhage developed in 19 cases (5.8%), and modified Rankin Scale 0-2 at 90days was seen in 129 cases (39.6%). The vast majority of patients (n?=?299, 94.3%) were transferred within 10km to the enrolling hospital.Conclusions
These results provide useful information about the emergent transfer system for patients with large vessel occlusion in a densely populated urban area. 相似文献10.

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11.

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12.

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13.

Introduction and Goal
Lacunar stroke is defined as an <1.5 cm diameter infarct located in the territory of a perforating artery, that is not accessible for direct study using conventional imaging techniques. Diagnosis requires exclusion of other causes. It usually occurs in the context of chronic cerebral small vessel disease, which can be suspected during the neurosonography study in the form of high pulsatility [PI] or resistance index [RI]. Clinical research was performed to confirm that PI and RI correlate with cerebral small vessel lesion burden and to determine whether these parameters are useful for supporting a lacunar origin (LO) in acute stroke.Material and Methods
We prospectively recorded internal carotid artery resistivity and the Fazekas score for all patients with acute ischemic stroke who met inclusion but not exclusion criteria over a 6-month period.Results
The study population comprised 74 patients. A correlation was observed between the Fazekas score and resistivity. Both parameters predicted a LO, with an area under the curve of .78 and .696, respectively. The optimal cut-offs were PI?=?.96/RI?=?.58 for screening (sensitivity, 96%) and PI?=?1.46/RI?=?.83 for confirmation (specificity, 89%).Conclusions
Doppler ultrasound is a useful technique for determining the LO of acute stroke. 相似文献14.

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15.

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16.

Background and Purpose
This study aimed to investigate factors associated with stroke recurrence and new-onset atrial fibrillation (AF) in patients with embolic stroke of undetermined source (ESUS).Methods
Between January 2005 and March 2012, a total of 1514 consecutive patients were admitted to our hospital with a diagnosis of acute ischemic stroke within 7 days after onset. Of these, 236 patients met the diagnostic criteria for ESUS. A retrospective analysis was performed of the following characteristics of these ESUS patients: medical history, comorbidities, and magnetic resonance imaging (MRI) findings including the deep and subcortical white matter hyperintensity (DSWMH) grade, drugs used for preventing recurrence, and clinical information such as NIH Stroke Scale scores on admission and outcomes evaluated by modified Rankin scale. The rate of recurrence after discharge and the frequency of new-onset AF were also determined.Results
There were 236 ESUS patients (141 men, mean age 70.2 ± 12.1 years). During the follow-up period, ranging from 7 days to 12.9 years (median 54.3 months), 32 (13.6%) and 44 (18.6%) of these patients had a recurrent ischemic stroke and new-onset AF, respectively. The most prevalent subtype of recurrent ischemic stroke was ESUS itself; this type of stroke occurred in 19 (59.3%) patients. AF was observed at stroke recurrence, but only 2 patients were diagnosed with cardioembolism. Multivariate analysis with a Cox proportional hazard model demonstrated that DSWMH grade greater than or equal to 3 was significantly associated with both recurrent ischemic stroke (hazard ratio 3.66, 95% confidence interval 1.69-7.92, P = .001) and new-onset AF (2.00, 1.03-3.90, .04).Conclusions
MRI classification of white matter hyperintensity could be effectively used as a predictor for recurrent ischemic stroke and new-onset AF in patients with ESUS. 相似文献17.

Background
Anticoagulant therapy is indicated for management of ischemic stroke patients with nonvalvular atrial fibrillation. We retrospectively investigated how oral anticoagulants were selected for ischemic stroke patients with nonvalvular atrial fibrillation.Methods
This study included 297 stroke patients with nonvalvular atrial fibrillation admitted to our hospital between September 2014 and December 2017, and who were subsequently transferred to other institutions or discharged home. Baseline clinical characteristics were compared between patients prescribed warfarin and those prescribed direct-acting oral anticoagulants.Results
In total, 280 of 297 (94.3%) patients received oral anticoagulant therapy, including 36 with warfarin, while 244 received direct oral anticoagulants. Age, percentage of heart failure, CHADS2 score before stroke onset, percentage of treatment with warfarin on admission, percentage of feeding tube at hospital discharge, and modified Rankin Scale at hospital discharge were significantly higher in the warfarin group versus the direct oral anticoagulants group, while creatinine clearance was significantly higher in the direct oral anticoagulant group. By multiple logistic regression, taking warfarin at admission and higher modified Rankin Scale at hospital discharge were associated with warfarin selection, while higher creatinine clearance was associated with direct oral anticoagulant selection (warfarin: odds ratio [OR] 7.10 [95% confidence interval {CI} 2.83-17.81]; modified Rankin Scale at hospital discharge: [OR] 1.47 [95% {CI} 1.06-2.04]; creatinine clearance: [OR] .97 [95% {CI} .95-.99]).Conclusions
Selection of oral anticoagulants in acute ischemic stroke patients with nonvalvular atrial fibrillation was influenced by warfarin use at admission, clinical severity at hospital discharge, and renal function. 相似文献18.

Introduction
Rural and critical access hospitals rely on the “drip and ship” practice using helicopter emergency medical services (HEMS). But those helicopter flights are an unusual environment with physical factors such as vibration and accelerations that could potentially affect the stability, and pharmacological properties of IV rtPA, an issue that has not been previously addressed.Materials and Methods
This was a prospective cohort study of consecutive acute ischemic stroke patients receiving IV rtPA through a Comprehensive Stroke Center from November 2015 to February 2017 to measure the effects of HEMS on the integrity and activity of rtPA by collecting residual medication left in the vial.Clinical Trial Registration
http://www.clinicaltrials.gov. NCT02752256Results
A total of 33 patients and rtPA samples were included; 18 patients who presented directly to the Comprehensive Stroke Center emergency department and 15 patients who received rtPA during air ambulance transfer. The median rtPA antigen concentration in the residual medication vial was 3.04 mg/mL (IQR: 1.24-3.87) in the HEMS group and 1.91 mg/mL (IQR: 1.33-2.60) in the controls (P = .168). There were no significant differences in rtPA activity or specific activity between the HEMS and control groups and there was no association between total HEMS flight time on overall rtPA specific activity.Conclusions
In summary, this study provides supportive evidence of the lack of a detrimental effect of the HEMS physical environment on the integrity of rtPA, therefore endorsing current drip and ship practices without infusion adjustments. 相似文献19.

Background
Pneumonia is a common complication after stroke which increases morbidity and mortality. This systematic review was conducted to evaluate the efficacy and safety of antibiotics for the prevention of pneumonia after acute stroke.Methods
Medline, EMBASE, and Cochrane databases were searched for randomized controlled trials comparing preventive antibiotics to placebo or no antibiotics after acute stroke. The primary outcome was poststroke pneumonia. Secondary outcomes were all infections, urinary tract infections, death, dependency, length of hospital stay, and adverse events. Treatment effects were summarized using random effects metaanalysis.Results
Six trials (4111 patients) were eligible for inclusion. The median National Institute of Health Stroke Scale score in included trials ranged from 5 to 16.5. The proportion of dysphagia ranged from 26% to 100%. Preventive antibiotics were commenced within 48hours after acute stroke. Compared to control, preventive antibiotics reduced the risk of poststroke pneumonia (RR .75, 95%CI ·.57-.99), and all infections (RR .58, 95%CI .48-.69). There was no significant difference in the risks of dependency (RR 0.99, 95%CI 0·80-1·11), or mortality (RR .96, 95%CI .78-1.19) between the preventive antibiotics and control groups. Preventive antibiotics did not increase the risk of elevated liver enzymes (RR 1.20, 95% CI .97-1.49). Preventive antibiotics had uncertain effects on the risks of other adverse events.Conclusion
Preventive antibiotics reduced the risk of post-stroke pneumonia. However, there is insufficient evidence to currently recommend routine use of preventive antibiotics after acute stroke. 相似文献20.
