Emotional reactions have been documented after tumor lesions and the other damages of the brain. The aim of this paper was to examine the correlation between frontal lobe lesions and emotional reactions in patients with stroke. The research included 118 patients after stroke. Lesion localization was defined on computed axial tomography records, whereas the area and perimeter of lesion were measured by AutoCAD 2004 software. Examinations by means of the Hamilton Rating Scale for Anxiety and Depression (HRSA and HRSD) were carried out 11-40 days after stroke. Statistic data were processed by simple linear/nonlinear regression, Cox's and the generalized linear model. A higher frequency of emotional reactions, i.e. anxiety, was determined in women after stroke (p = 0.024). A negative correlation between the lesion size and the intensity of anxiety manifestations was determined (Spearman's r = -0.297; p = 0.001). Anxiety was more frequent in patients with frontal lobe lesions in the dominant hemisphere (interaction: frontal lesion * hand dominant hemisphere, p = 0.017). Also, HRSD score values showed the tendency for lesser decline in case of greater frontal lobe lesions in relation to lesions of other regions of prosencephalon (interaction: frontal lesion * lesion area, p = 0.001). The results of this study indicate the correlation between evolutionary younger structures of the central nervous system and emotional reactions of man. Therefore, it is necessary to undertake proper early psychopharmacotherapy in the vulnerable group of patients.

Because of the aging population in low- and middle-income countries, cerebrovascular disease is expected to remain a leading cause of death. Little has been published about stroke in Peru. We conducted a retrospective cohort study of hospitalized stroke patients at a referral center hospital in Lima, Peru to explore factors associated with functional outcome among stroke patients. We identified 579 patients hospitalized for ischemic stroke or intracerebral hemorrhage stroke at the National Institute of Neurologic Sciences in Lima, Peru in 2008 and 2009. A favorable outcome was defined as a modified Rankin scale score of ≤ 2 at discharge. The mean age was 63.3 years; 75.6% had ischemic stroke; the average duration of stay was 17.3 days. At hospital discharge, 231 (39.9%) had a favorable outcome. The overall mortality rate was 5.2%. In multivariate models, the likelihood of having a favorable outcome decreased linearly with increasing age (P = .02) and increasing National Institutes of Health Stroke Scale (NIHSS) score (P = .02). Favorable outcome was also associated with male gender (relative risk [RR] 1.2; 95% confidence interval [CI] 1.0-1.5) and divorced status (RR 1.3; 95% CI 1.1-1.7). Patients on Salud Integral de Salud (SIS; public assistance-type insurance; RR 0.7; 95% CI 0.5-1.0) were also less likely to have a favorable outcome. Favorable outcome after stroke was independently associated with younger age, a lower NIHSS score, male gender, being divorced, and not being on SIS insurance. These findings suggest that additional study of worse functional outcomes in patients with SIS insurance be conducted and confirm the importance of risk adjustment for age, stroke severity (according to the NIHSS scale), and other socioeconomic factors in outcomes studies. Future studies should preferentially assess outcome at 30 days and 6 months to provide more reliable comparisons and allow additional study of Peruvian end-of-life decision-making and care.

Only 37 cases of stroke during or soon after long-haul flights have been published to our knowledge. In this retrospective observational study, we searched the Royal Melbourne Hospital prospective stroke database and all discharge summaries from 1 September 2003 to 30 September 2014 for flight-related strokes, defined as patients presenting with stroke within 14days of air travel. We hypothesised that a patent foramen ovale (PFO) is an important, but not the only mechanism, of flight-related stroke. We describe the patient, stroke, and flight characteristics. Over the study period, 131 million passengers arrived at Melbourne airport. Our centre admitted 5727 stroke patients, of whom 42 (0.73%) had flight-related strokes. Flight-related stroke patients were younger (median age 65 versus 73, p<0.001), had similar stroke severity, and received intravenous thrombolysis more often than non-flight-related stroke patients. Seven patients had flight-related intracerebral haemorrhage. The aetiology of the ischaemic strokes was cardioembolic in 14/35 (40%), including seven patients with confirmed PFO, one with atrial septal defect, four with atrial fibrillation, one with endocarditis, and one with aortic arch atheroma. Paradoxical embolism was confirmed in six patients. Stroke related to air travel is a rare occurrence, less than one in a million. Although 20% of patients had a PFO, distribution of stroke aetiologies was diverse and was not limited to PFO and paradoxical embolism. Copyright © 2016 Elsevier Ltd. All rights reserved.

Little is known about potential ethnic differences in stroke incidence. We compared incidence and time trends of ischemic stroke and primary intracerebral hemorrhage in South Asian, Chinese and white persons in a population-based study. Population based census and administrative data analysis in the provinces of Ontario and British Columbia, Canada using validated ICD 9/ICD 10 coding for acute ischemic and hemorrhagic stroke (1997-2010). There were 3290 South Asians, 4444 Chinese and 160944 white patients with acute ischemic stroke and 535 South Asian, 1376 Chinese and 21842 white patients with intracerebral hemorrhage. South Asians were younger than whites at onset of stroke (70 vs. 74 years for ischemic and 67 vs. 71 years for hemorrhagic stroke). Age and sex adjusted ischemic stroke incidence in 2010 was 43% lower in Chinese and 63% lower in South Asian than in White patients. Age and sex adjusted intracerebral hemorrhage incidence was 18% higher in Chinese patients, and 66% lower in South Asian relative to white patients. Stroke incidence declined in all ethnic groups (relative reduction 69% in South Asians, 25% in Chinese, and 34% in white patients for ischemic stroke and for intracerebral hemorrhage, 79% for South Asians, 51% for Chinese and 30% in white patients). Although stroke rates declined across all ethnic groups, these rates differed significantly by ethnicity. Further study is needed to understand mechanisms underlying the higher ischemic stroke incidence in white patients and intracerebral hemorrhage in Chinese patients.

Although there have been many studies on seizures following stroke, there is still much we do not know about them. In this study, we evaluated the characteristics of seizures in stroke patients. There were 2267 patients with a first-ever stroke, and after excluding 387 patients, 1880 were available for analysis. Of these 1880 patients, we evaluated 200 patients with seizures and 400 patients without seizures. We investigated the seizures according to age, gender, stroke type, the aetiology of ischaemic stroke and the localisation of the lesion. The seizures were classified as early onset and late onset and the seizure type as partial, generalised or secondarily generalised. Seizures occurred in 200 (10.6%) of 1880 strokes. The number of patients with seizures were 138 (10.6%) in ischaemic stroke group and 62 (10.7%) in haemorrhagic stroke group. Patients with ischaemic strokes had 41 embolic (29.7%) and 97 thrombotic (70.3%) origin, and these were not statistically significant in comparison with controls. Cortical involvement for the development of seizures was the most important risk factor (odds ratios = 4.25, p < 0.01). It was concluded that embolic strokes, being younger than 65 years old, and cortical localisation of stroke were important risks for developing seizures.

Acupuncture is considered a complementary and alternative medicine in many countries. The purpose of this study was to report the pattern of acupuncture use and associated factors in patients with stroke. We used claims data from Taiwan's National Health Insurance Research Database and identified 285001 new-onset stroke patients in 2000-2008 from 23 million people allover Taiwan. The use of acupuncture treatment after stroke within one year was identified. We compared sociodemographics, coexisting medical conditions, and stroke characteristics between stroke patients who did and did not receive acupuncture treatment. The use of acupuncture in stroke patients increased from 2000 to 2008. Female gender, younger age, white-collar employee status, higher income, and residence in areas with more traditional Chinese medicine (TCM) physicians were factors associated with acupuncture use in stroke patients. Ischemic stroke (odds ratio [OR] 1.21, 95 % confidence interval [CI] 1.15-1.28), having no renal dialysis (OR 2.76, 95 % CI 2.45-3.13), receiving rehabilitation (OR 3.20, 95 % CI 3.13-3.27) and longer hospitalization (OR 1.23, 95 % CI 1.19-1.27) were also associated with acupuncture use. Stroke patients using rehabilitation services were more likely to have more acupuncture visits and a higher expenditure on acupuncture compared with stroke patients who did not receive rehabilitation services. The application of acupuncture in stroke patients is well accepted and increasing in Taiwan. The use of acupuncture in stroke patients is associated with sociodemographic factors and clinical characteristics.

Young stroke patients have a strong desire to return to the society, but few studies have been conducted on their rehabilitation training items, intensity, and prognosis. We analyzed clinical data of young and middle-aged/older stroke patients hospitalized in the Department of Neurological Rehabilitation, China Rehabilitation Research Center, Capital Medical University, China from February 2014 to May 2015. Results demonstrated that hemorrhagic stroke (59.6%) was the primary stroke type found in the young group, while ischemic stroke (60.0%) was the main type detected in the middle-aged/older group. Compared with older stroke patients, education level and incidence of hyperhomocysteinemia were higher in younger stroke patients, whereas, incidences of hypertension, diabetes, and heart disease were lower. The average length of hospital stay was longer in the young group than in the middle-aged/older group. The main risk factors observed in the young stroke patients were hypertension, drinking, smoking, hyperlipidemia, hyperhomocysteinemia, diabetes, previous history of stroke, and heart disease. The most accepted rehabilitation program consisted of physiotherapy, occupational therapy, speech therapy, acupuncture and moxibustion. Average rehabilitation training time was 2.5 hours/day. Barthel Index and modified Rankin Scale scores were increased at discharge. Six months after discharge, the degree of occupational and economic satisfaction declined, and there were no changes in family life satisfaction. The degrees of other life satisfaction (such as friendship) improved. The degree of disability and functional status improved significantly in young stroke patients after professional rehabilitation, but the number of patients who returned to society within 6 months after stroke was still small.

Since non-vitamin K antagonist oral anticoagulants (NOACs) were released for clinical use, many studies have investigated its effectiveness in stroke prevention. In this study, to determine whether or not there is a difference in outcome in secondary stroke prevention between warfarin and NOACs, patients with embolic stroke with newly prescribed anticoagulants were prospectively analyzed. Patients with acute ischemic stroke, who newly started anticoagulant therapy, were consecutively asked to participate in this study. Enrolled patients (76.3 ± 11.0 years old) were classified into warfarin (n = 48), dabigatran (n = 73), rivaroxaban (n = 49), and apixaban (n = 65). The outcome in 1 year was prospectively investigated at outpatient clinic or telephone interview. Recurrence of stroke and death was considered as the critical incidence. The prevalence of risk factors was not different among all medicines. Patients with dabigatran showed significantly younger onset age (P < .001: 72.2 years old) and milder neurologic deficits than patients on other medicines (P < .001). Cumulative incident rates were 7.1%, 15.3%, 19.0%, and 29.7% for dabigatran, apixaban, rivaroxaban, and warfarin, respectively. Dabigatran showed relatively better outcome compared with warfarin (P = .069) and rivaroxaban (P = .055). All patients on NOACs presented lower cumulative stroke recurrence compared with warfarin. Even in the situation of secondary stroke prevention, noninferiority of NOACs to warfarin might be demonstrated. Copyright © 2018 National Stroke Association. Published by Elsevier Inc.

Intravenous thrombolysis and intra-arterial thrombectomy are now the standard therapies for patients with acute ischemic stroke. In-house strokes have often been overlooked even at stroke centers and there is no consensus on how they should be managed. Perioperative stroke happens rather frequently but treatment protocol is lacking, In China, the issue of in-house strokes has not been explored. The aim of this study is to explore the current management of in-house stroke and identify the common risk factors associated with perioperative strokes. Altogether, 51,841 patients were admitted to a tertiary hospital in Shanghai and the records of those who had a neurological consult for stroke were reviewed. Their demographics, clinical characteristics, in-hospital complications and operations, and management plans were prospectively studied. Routine laboratory test results and risk factors of these patients were analyzed by multiple logistic regression model. From January 1, 2015, to December 31, 2015, over 1800 patients had neurological consultations. Among these patients, 37 had an in-house stroke and 20 had more severe stroke during the postoperative period. Compared to in-house stroke patients without a procedure or operation, leukocytosis and elevated fasting glucose levels were more common in perioperative strokes. In multiple logistic regression model, perioperative strokes were more likely related to large vessel occlusion. Patients with perioperative strokes had different risk factors and severity from other in-house strokes. For these patients, obtaining a neurological consultation prior to surgery may be appropriate in order to evaluate the risk of perioperative stroke. Copyright © 2017. Published by Elsevier Inc.

Hypertension can be found in up to 80% of patients with acute stroke. Many factors have been related to this phenomenon such as age, history of hypertension, and stroke severity. The aim of our study was to determine the relationship between infarct volume and blood pressure, at admission, in young patients with acute ischemic stroke. Patients younger than 55 years old admitted within 24 hours of ischemic stroke were included. Socio-demographic variables, systolic blood pressure, diastolic blood pressure, and infarct volume at admission were assessed. Statistical analysis: mean and SEM for quantitative variables, percentages for qualitative, and Spearman correlations ( p value < 0.05 was considered statistically significant). Twenty-two patients (12 men), mean age: 44.64 ± 1.62 years. The most frequent vascular risk factors were: hypertension, smoking, and overweight (40.9%). Mean systolic and diastolic blood pressure on admission were: 143.27 ± 6.57 mmHg and 85.14 ± 3.62 mmHg, respectively. Infarct volume: 11.55 ± 4.74 ml. Spearman correlations: systolic blood pressure and infarct volume: p = 0.15 r : -0.317; diastolic blood pressure and infarct volume: p = 0.738 r: -0.76. In our series of young patients with acute ischemic stroke, large infarct volume was not associated with high blood pressure at admission.

We sought to determine the rate of urine toxicology screening, differences in testing, and outcomes among patients with stroke and TIA presenting to a tertiary care emergency department. In this retrospective cohort study, patients admitted with stroke or TIA to a single tertiary care stroke center between June 2005 and January 2007 were identified through a stroke database. Factors that predicted urine toxicology screening of patients and a positive test, and discharge outcomes of patients based on toxicology result were analyzed. Stroke severity, treatment with tissue plasminogen activator, discharge status, and stroke etiology were compared between toxicology positive and negative patients. A total of 1,024 patients were identified: 704 with ischemic stroke, 133 with intracerebral hemorrhage, and 205 with TIA. Urine toxicology screening was performed in 420 patients (40%); 11% of these studies were positive for cocaine (19% younger than 50 years and 9% 50 years or older). Factors that significantly predicted the performance of a urine toxicology screen were younger age (<50 years) and black race (<0.001). Positive toxicology screens occurred in a broad range of patients. There were no significant differences in admission NIH Stroke Scale score, stroke etiology, and discharge status between toxicology-positive and -negative patients. In this study, patients with stroke and TIA who were young and black were more likely to have urine toxicology screening. Eleven percent of all tested patients (and 9% of patients 50 years or older) were positive for cocaine. To avoid disparities, we suggest that all stroke and TIA patients be tested.

Up to a third of strokes are rendered cryptogenic or of undetermined etiology. This number is specifically higher in younger patients. At times, inadequate diagnostic workups, multiple causes, or an under-recognized etiology contributes to this statistic. Embolic stroke of undetermined source, a new clinical entity particularly refers to patients with embolic stroke for whom the etiology of embolism remains unidentified despite through investigations ruling out established cardiac and vascular sources. In this article, we review current classification and discuss important clinical considerations in these patients; highlighting cardiac arrhythmias and structural abnormalities, patent foramen ovale, paradoxical sources, and potentially under-recognized, vascular, inflammatory, autoimmune, and hematologic sources in relation to clinical practice.

This is a multi-center, hospital-based study aiming to estimate social factors influencing pre-hospital times of arrival in acute ischemic stroke, with a perspective of finding ways to reduce arrival time and to augment the number of patients eligible for intra-arterial thrombolysis. Acute ischemic stroke patients who presented at the emergency units of four major general public hospitals were registered. We assessed information concerning demographics, time of presentation, clinical situation, imaging, treatment, and socioeconomic factors. The sample was divided in two sub-samples, based on the time of arrival since onset of symptoms, and was statistically analyzed. During one calendar year (2005), 907 patients were registered. Among them 34.6% arrived in the first 6 h from symptom onset, 38.7% arrived between 6 and 24 h, 18.1% after 24 h and for 8.6% the time of onset was unknown. Younger age (P = 0.007), transfer with ambulatory service (Ρ = 0.002), living with a mate (Ρ = 0.004), and higher educational level (P < 0.005) were factors which correlated significantly with early arrival at the hospital. Instructing patients at high risk for stroke to live with a housemate appears beneficial for timely arrival at the hospital. The establishment of dedicated acute stroke call and transportation center should improve the percentage of early arrival. A national information campaign is needed to increase the level of awareness of the population concerning beneficial social behaviors and optimal reaction to symptoms of acute ischemic stroke.

Family history of stroke is an established risk factor for stroke. We evaluated whether family history of stroke predisposed to certain stroke subtypes and whether it differed by sex in young patients with stroke. We used data from the Stroke in Fabry Patients study, a large prospective, hospital-based, screening study for Fabry disease in young patients (aged <55 years) with stroke in whom cardiovascular risk factors and family history of stroke were obtained and detailed stroke subtyping was performed. A family history of stroke was present in 1578 of 4232 transient ischemic attack and ischemic stroke patients (37.3%). Female patients more often had a history of stroke in the maternal lineage (P=0.027) than in the paternal lineage. There was no association with stroke subtype according to Trial of Org 10172 in Acute Stroke Treatment nor with the presence of white matter disease on brain imaging. Patients with dissection less frequently reported a family history of stroke (30.4% versus 36.3%; P=0.018). Patients with a parental history of stroke more commonly had siblings with stroke (3.6% versus 2.6%; P=0.047). Although present in about a third of patients, a family history of stroke is not specifically related to stroke pathogenic subtypes in patients with young stroke. Young women with stroke more often report stroke in the maternal lineage. URL: http://www.clinicaltrials.gov. Unique identifier: NCT00414583. © 2015 American Heart Association, Inc.

Native Hawaiians and other Pacific Islanders (NHOPI) with ischemic stroke have younger age of stroke onset compared with whites. However, ethnic differences in stroke subtypes in this population have been inadequately studied. Consecutive young adult patients (aged ≤55 years) who were hospitalized for ischemic stroke between 2006 and 2012 at a tertiary center in Honolulu were studied. Clinical characteristics and stroke subtypes based on pathophysiological TOAST classification (Trial of Org 10172) of NHOPI and Asians were compared with whites. A total of 427 consecutive young adult (mean age, 46.7±7.8 years) patients (NHOPI 45%, Asians 38%, and whites 17%) were studied. NHOPI had a higher prevalence of hypertension, diabetes mellitus, prosthetic valve, higher body mass index, hemoglobin A1c, and lower high-density lipoprotein than whites (all P<0.05). Stroke subtype distribution was not different between the ethnic groups. Specifically, the prevalence of small-vessel disease was similar between NHOPI (26.6%), whites (28.4%), and Asians (24.8%). In the univariate analyses, the use of intravenous tissue-type plasminogen activator was lower among NHOPI (4.7%; P=0.01) and Asians (3.1%; P=0.002) than among whites (12.5%). In the multivariable model, NHOPI (odds ratio, 0.35; 95% confidence interval, 0.12-0.98) and Asians (odds ratio, 0.23; 95% confidence interval, 0.07-0.74) were less likely to be treated with intravenous tissue-type plasminogen activator than whites. NHOPI have greater cardiovascular risk factors than whites, but there were no differences in stroke subtypes between the ethnic groups. Furthermore, NHOPI and Asians may be less likely to be treated with intravenous tissue-type plasminogen activator than whites. © 2016 American Heart Association, Inc.

Hospital charges for stroke patients.

Stroke is a common disease with a yearly cost in the United States of approximately $30 billion. The increasing prevalence of managed care and cost-containment measures may affect the delivery of stroke care now and in the future. This study was performed to determine (1) hospital charges and test utilization for stroke patients and (2) the effectiveness of educational efforts in modifying test utilization and related hospital charges. Patients with a diagnosis of stroke who were discharged from either the neurology service or another service of the Department of Medicine (DOM) were identified. Data on test utilization and hospital charges were collected and analyzed. Following this analysis, educational sessions were held in an effort to reduce the use of specific diagnostic tests. The effectiveness of these methods was studied in a second group of stroke patients. In the baseline period there were 303 stroke patients, of which 262 (86%) were discharged from the neurology service and 41 (14%) were discharged from other services of the DOM. Patients on the neurology service had a lower mean length of stay than patients on the other services of the DOM (9.2 days versus 10.5 days) and lower mean total charges per case ($13,149 versus $15,727), although the respective differences were not statistically significant. Patient on the neurology service were more likely to have both brain CT and MRI performed (82 of 262 patients, 31.3%) than patients on the other services of the DOM (4 of 41, 9.8%, P = .005). In addition, patients on the neurology service were more likely to undergo a transthoracic echocardiogram than patients on the other services of the DOM (71.8% versus 53.7%, P = .025). After educational sessions, the percentage of stroke patients on the neurology service having both CT and MRI fell from 31.3% to 17.7% (P = .005), and the number of stroke patients having a transthoracic echocardiogram fell from 71.8% to 60.3% (P = .025).

The risk factor profiles, management and outcome have significant difference between stroke subsets. Aim of this study was to investigate the risk for the two most common subtypes of stroke in Bangladeshi population. Seventy cases of hemorrhagic stroke (HS) and 105 cases of confirmed ischemic stroke (IS) were recruited from the Shaheed Suhrawardy Medical College Hospital (ShSMCH) and Dhaka Medical College Hospital between January-June 2011. Total 171 age, sex matched controls were selected from the hospitalized patients with history of no stroke ever. Average hemorrhagic stroke patients (60.4 ± 12.3 years) were younger than both ischemic strokes (63.5 ± 13 years). Family history of premature cardiovascular death was found more in HS patients (p = 0.001). Multivariate logistic regression showed, in IS model 'less fruit consumption (OR 4.6), table salt intake (OR 8.15), psychosocial stress (OR 3.5), abnormal ECG (OR 3.6) and Increased WHR (OR 6.9) appeared as significant predictors adjusted for all potential candidate confounders. In HS model less fruit consumption (OR 5.0), table salt intake (OR 9.9), Stress (OR 4.1), family history of cardiovascular disease (CVD) death (OR 11.3), hypertension (OR 43), aspirin intake (OR 4.5) and increased WHR (OR 3.7) remained as significant predictors.

Riks-Stroke, the Swedish Stroke Register, was used to explore patient characteristics and stroke services as determinants of patient dissatisfaction with acute in-hospital care. All 79 hospitals in Sweden admitting acute stroke patients participate in Riks-Stroke. During 2001 to 2007, 104,876 patients (87% of survivors) responded to a follow-up questionnaire 3 months after acute stroke; this included questions on satisfaction with various aspects of stroke care. The majority (>90%) were satisfied with acute in-hospital stroke care. Dissatisfaction was closely associated with outcome at 3 months. Patient who were dependent regarding activities of daily living, felt depressed, or had poor self-perceived general health were more likely to be dissatisfied. Dissatisfaction with global acute stroke care was linked to dissatisfaction with other aspects of care, including rehabilitation and support by community services. Patients treated in stroke units were less often dissatisfied than patients in general wards, as were patients who had been treated in a small hospital (vs medium or large hospitals) and patient who had participated in discharge planning. In multivariate analyses, the strongest predictor of dissatisfaction with acute care was poor outcome (dependency regarding activities of daily living, depressed mood, poor self-perceived health). Dissatisfaction with in-hospital acute stroke care is part of a more extensive complex comprising poor functional outcome, depressive mood, poor self-perceived general health, and dissatisfaction not only with acute care but also with health care and social services at large. Several aspects of stroke care organization are associated with a lower risk of dissatisfaction.

Data regarding durability and midterm benefits of mitral valve (MV) repair in elderly patients are scarce. To evaluate the feasibility and safety of MV repair in elderly patients, we performed a retrospective data analysis. We compared clinical outcomes in younger patients (<75 years: n = 462) and older patients (≥75 years: n = 100) undergoing MV repair with or without tricuspid valve (TV) repair. The primary end-point was 30-day mortality. The preoperative risk profile (EuroSCORE, NYHA class, percentage pulmonary hypertension, percentage diabetes) was higher in older patients compared with younger patients. Nevertheless, operative complications such as low cardiac output syndrome, stroke, infections, the need of haemofiltration and IABP use did not differ significantly between the two groups. The thirty-day mortality rate was 0% in older patients and 1% in younger patients (P = 0.30). In the subgroup of patients with double valve repair, the 30-day mortality rate in older patients (n = 28) and younger patients (n = 46) was 0 and 4%, respectively (P = 0.27). In older and younger patients, the 6-month mortality rate was 4 and 2%, respectively (P = 0.16), and the 1-year mortality rate was 10 and 3%, respectively (P = 0.001). The propensity score-adjusted odds ratio of 1-year mortality with the group of younger patients as a reference was 2.04 (95% confidence interval: 0.77-5.40; P = 0.15) for older patients. Freedom from 1-year reoperation did not differ significantly between age groups. Data demonstrate excellent postoperative mortality rates in older patients undergoing MV repair with or without TV repair. Consequently, even in older patients with numerous comorbidities, MV repair should be considered a suitable surgical method. © The Author 2014.

Malignant stroke is an intracranial herniation syndrome caused by cerebral oedema after a large hemispheric or cerebellar stroke. Malignant middle cerebral artery infarction is a devastating disease with a mortality around 80% despite intensive medical treatment. Decompressive craniectomy reduces mortality and improves functional outcome - especially in younger patients (age ≤ 60 years). Decompression of the posterior fossa is a life-saving procedure in patients with malignant cerebellar infarctions and often leads to good neurological outcome.

Ipsilateral hemiparesis in ischemic stroke patients.

To investigate clinical characteristics of ipsilateral hemiparesis in ischemic stroke patients. Patients with acute ischemic stroke were prospectively examined. Ipsilateral hemiparesis was defined as hemiparesis ipsilateral to recent stroke lesions. Patients with ipsilateral hemiparesis were examined with functional neuroimaging studies including transcranial magnetic stimulation (TMS) and functional MRI. Of 8360 patients, ipsilateral hemiparesis was detected in 14 patients (0.17%, mean age 71±6 years, eight men). Lesions responsible for the recent strokes were located in the frontal cortex in three patients, corona radiata in seven, internal capsule in one, and pons in three. These lesions were located along the typical route of the corticospinal tract in all but one patient. Thirteen patients also had a past history of stroke contralateral to the recent lesions; 12 of these had motor deficits contralateral to past stroke lesions. During TMS, ipsilateral magnetic evoked potentials were evoked in two of seven patients and contralateral potentials were evoked in all seven. Functional MRI activated cerebral hemispheres ipsilaterally in eight of nine patients and contralaterally in all nine. Most patients with ipsilateral hemiparesis had a past history of stroke contralateral to the recent one, resulting in motor deficits contralateral to the earlier lesions. Moreover, functional neuroimaging findings indicated an active crossed corticospinal tract in all of the examined patients. Both findings suggest the contribution of the uncrossed corticospinal tract contralateral to stroke lesions as a post-stroke compensatory motor system. © 2016 John Wiley & Sons A/S.

PURPOSE: Angle-closure glaucoma is rare in children and young adults. Only scattered cases associated with specific clinical entities have been reported. We evaluated the findings in patients in our database aged 40 or younger with angle closure. METHODS: Our database was searched for patients with angle closure who were 40 years old or younger. Data recorded included age at initial consultation; age at the time of diagnosis; gender; results of slit-lamp examination, gonioscopy, and ultrasound biomicroscopy (from 1993 onward); clinical diagnosis; and therapy. Patients with previous incisional surgery were excluded, as were patients with anterior chamber proliferative mechanisms leading to angle closure. RESULTS: Sixty-seven patients (49 females, 18 males) met entry criteria. Mean age (+/- SD) at the time of consultation was 34.4 +/- 9.4 years (range, 3-68 years). Diagnoses included plateau iris syndrome (35 patients), iridociliary cysts (8 patients), retinopathy of prematurity (7 patients), uveitis (5 patients), isolated nanophthalmos (3 patients), relative pupillary block (2 patients), Weill-Marchesani syndrome (3 patients), and 1 patient each with Marfan syndrome, miotic-induced angle closure, persistent hyperplastic primary vitreous, and idiopathic lens subluxation. CONCLUSION: The etiology of angle closure in young persons is different from that in the older population and is typically associated with structural or developmental ocular anomalies rather than relative pupillary block. Following laser iridotomy, these eyes should be monitored for recurrent angle closure and the need for additional laser or incisional surgical intervention. PMID:12545694

Significant numbers of younger persons with stroke should be given the opportunity to return to work. The aim of this study was to investigate factors of importance for return to work among persons after first ever stroke, in the age range 18-55 years. A questionnaire was sent to all persons who had experienced a first ever stroke, 18-55 years of age, registered in the Swedish national quality register for stroke care, Riks-Stroke. Of the 1068 who answered the questionnaire, 855 (539 men and 316 women) were in paid employment before their stroke, and were included in this study. Sixty-five percent returned to work and, of these, an equal proportion were men and women. Significant factors associated with return to work were the perceived importance of work (odds ratio (OR) 5.10), not perceiving themselves as a burden on others (OR 3.33), support from others for return to work (OR 3.66), retaining the ability to run a short distance (OR 2.77), and higher socioeconomic codes (OR 2.12). A negative association was found between those rehabilitated in wards intended for younger persons and return to work (OR 0.37). External support from others, and positive attitudes towards return to work, were factors associated with successful return to work after stroke. Contrary to what was expected, independence in personal activities of daily living and cognitive factors were not associated with return to work to the same extent as persistent higher level of physical functions, such as ability to run a short distance.

Background Each year, approximately 12,000 Australians of working age survive a stroke. As a group, younger stroke survivors have less physical impairment and lower mortality after stroke compared with older survivors; however, the psychosocial and economic consequences are potentially substantial. Most of these younger stroke survivors have responsibility for generating an income or providing family care and indicate that their primary objective is to return to work. However, effective vocational rehabilitation strategies to increase the proportion of younger stroke survivors able to return to work, and information on the key target areas for those strategies, are currently lacking. Methods/Design This multi-centre, three year cohort study will recruit a representative sample of younger (< 65 years) stroke survivors to determine the modifiable predictors of subsequent return to work. Participants will be recruited from the New South Wales Stroke Services (SSNSW) network, the only well established and cohesively operating and managed, network of acute stroke units in Australia. It is based within the Greater Metropolitan area of Sydney including Wollongong and Newcastle, and extends to rural areas including Wagga Wagga. The study registration number is ACTRN12608000459325. Discussion The study is designed to identify targets for rehabilitation-, social- and medical-intervention strategies that promote and maintain healthy ageing in people with cardiovascular and mental health conditions, two of the seven Australian national health priority areas. This will rectify the paucity of information internationally around optimal clinical practice and social policy in this area. PMID:19519918

Imaging diagnosis is essential for treatment planning in stroke patients. However, use of these techniques varies due to uncertainty about their effectiveness. Our purpose was to describe the use of CT and MRI in stroke and transient ischaemic attack (TIA) over 5years in hospitals belonging to the Canary Islands Health Service and analyse interhospital variability based on routinely collected administrative data. We gathered the minimum basic dataset (MBDS) from patients diagnosed with stroke or TIA between 2005 and 2010 in 4hospitals. Patients' age, sex, procedures, secondary diagnoses, and duration of hospital stay were also recorded. We conducted a descriptive analysis of patient characteristics and a bivariate analysis using the t test and the chi square test to detect differences between patients assessed and not assessed with MRI. Logistic regression was used to analyse unequal access to MRI. Our study included 10,487 patients (8,571 with stroke and 1,916 with TIA). The percentage of stroke patients undergoing a CT scan increased from 89.47% in 2005 to 91.50% in 2010. In these patients, use of MRI also increased from 25.41% in 2005 to 36.02% in 2010. Among patients with TIA, use of CT increased from 84.64% to 88.04% and MRI from 32.53% to 39.13%. According to our results, female sex, younger age, and presence of comorbidities increase the likelihood of undergoing MRI. Copyright © 2017 Sociedad Española de Neurología.

Towfighi, Amytis; Markovic, Daniela; Ovbiagele, Bruce

2012-01-01

Type 2 diabetes rates in the general population have risen with the growing obesity epidemic. Knowledge of temporal patterns and factors associated with comorbid diabetes among stroke patients may enable health practitioners and policy makers to develop interventions aimed at reducing diabetes rates, which may consequently lead to declines in stroke incidence and improvements in stroke outcomes. Using the Nationwide Inpatient Sample (NIS), a nationally representative data set of US hospital admissions, we assessed trends in the proportion of acute ischemic stroke (AIS) patients with comorbid diabetes from 1997 to 2006. Independent factors associated with comorbid diabetes were evaluated using multivariable logistic regression. Over the study period, the absolute number of AIS hospitalizations declined by 17% (from 489,766 in 1997 to 408,378 in 2006); however, the absolute number of AIS hospitalizations with comorbid type 2 diabetes rose by 27% [from 97,577 (20%) in 1997 to 124,244 (30%) in 2006, p < 0.001]. The rise in comorbid diabetes over time was more pronounced in patients who were relatively younger, Black or 'other' race, on Medicaid, or admitted to hospitals located in the South. Factors independently associated with higher odds of diabetes in AIS patients were Black or 'other' versus White race, congestive heart failure, peripheral vascular disease, history of myocardial infarction, renal disease and hypertension. Although hospitalizations for AIS in the US decreased from 1997 to 2006, there was a steep rise in the proportion with comorbid diabetes (from 1 in 5 to almost 1 in 3). Specific patient populations may be potential targets for mitigating this trend. Copyright © 2012 S. Karger AG, Basel.

It remains unclear whether the characteristics of ischemic stroke in patients with cancer (ISC) differ from usual ischemic strokes (non-ISC). Although a small number of studies have been conducted to characterize ISC, the status of cancer has rarely been considered seriously. We aimed to investigate the features of ISC according to the status of cancer, and compare their characteristics with those of non-ISC. We assessed and classified 204 ISC patients into two groups: 104 with active (ISC-active) and 100 with inactive (ISC-inactive) cancer. For each ISC patient, two age- and gender-matched ischemic stroke patients without history of cancer were selected as non-ISC control subjects. We compared the clinical/laboratory data, stroke mechanisms, and diffusion weighted imaging (DWI) lesion patterns between ISC-active and non-ISC patients, and between ISC-inactive and non-ISC patients. ISC-active patients demonstrated higher C-reactive protein (CRP) and D-dimer, more frequent cryptogenic stroke and patterns of multiple DWI lesions (in bilateral anterior or in anterior and posterior circulations), and less prevalent conventional risk factors than non-ISC patients, while ISC-inactive patients revealed no such marked differences. Among ISC-active patients, both elevated CRP and D-dimer levels were associated with cryptogenic mechanism and multiple lesion patterns. Furthermore, ISC-active patients with cryptogenic strokes tended to have multiple lesion patterns and metastasis. ISC-active, but not ISC-inactive, is distinct in terms of risk factors, stroke mechanisms, and lesion patterns. Chronic inflammation and an activated coagulation system may contribute to the pathogenic mechanism of strokes, the extent of each depending on the activity and severity of cancer. © 2013 The Authors.

ABSTRACT Objective Approximately 30% of individuals who initially present with stroke are found to be stroke mimics (SM), with functional/psychological SM (FSM) accounting for up to 6.4% of all stroke presentations. Middle Eastern countries may have higher rates of somatization of emotional distress. The aim of this study was to evaluate the incidence and characteristics of FSM at a large general hospital in the Middle East. Methods All patients presenting with an initial diagnosis of stroke from June 2015 to September 2016 were eligible for this study. Clinical and sociodemographic data were obtained from the hospital's stroke database. All SM and strokes were diagnosed by Joint Commission International–certified stroke program neurologists. SM was defined as any discharge diagnosis (other than acute stroke) for symptoms that prompted initial admission for suspected stroke. FSM were compared with medical stroke mimics (MSM) and strokes (ischemic, hemorrhagic, and transient ischemic attacks). Results A total of 1961 patients were identified; 161 FSM (8.2%), 390 MSM (19.9%), and 1410 strokes (71.9%) (985 ischemic strokes, 196 transient ischemic attacks, 229 intracerebral hemorrhages). Admission with FSM was related to patients' nationality, with the highest frequency in Arabic (15.6%) and African (16.8%) patients. FSM patients were younger, more often female, and had fewer cardiovascular risk factors except for smoking compared with the strokes. FSM patients presented with more left-sided weakness and had more magnetic resonance imagings than the stroke and MSM groups. A total of 9.9% of FSM patients received thrombolysis versus only 0.5% of the MSM and 16.4% of ischemic strokes. Conclusions FSM frequencies varied by nationality, with Arab and African nationals being twice as prevalent. Stress, vulnerable status as expats, sociopolitical instability, and exposure to trauma are proposed as potential factors contributing to FSM. PMID:29394187

Patient-led therapy, in which patients work outside therapy sessions without direct supervision, is a possible way to increase the amount of therapy stroke patients' receive without increasing staff demands. Here, we report patients' views of patient-led mirror therapy and lower limb exercises. 94 stroke survivors with upper and lower limb limitations at least 1-week post-stroke undertook 4 weeks of daily patient-led mirror therapy or lower limb exercise, then completed questionnaires regarding their experience and satisfaction. A convenience random sample of 20 participants also completed a semi-structured telephone interview to consider their experience in more detail and to capture their longer term impressions. Participants were generally positive about patient-led therapy. About 71% found it useful; 68% enjoyed it; 59% felt it "worked" and 88% would recommend it to other patients. Exercise was viewed more positively than the mirror therapy. Difficulties included arranging the equipment and their position, particularly for more severe strokes, loss of motivation and concerns about working unsupervised. Patient-led mirror therapy and lower limb exercises during in-patient rehabilitation is generally feasible and acceptable to patients but "light touch" supervision to deal with any problems, and strategies to maintain focus and motivation are needed. Implications for Rehabilitation Most stroke patients receive insufficient therapy to maximize recovery during rehabilitation. As increases in staffing are unlikely there is an imperative to find ways for patients to increase the amount of exercise and practice of functional tasks they undertake without increasing demands on staff. Patient-led therapy (also known as patient-directed therapy or independent practice), in which patients undertake exercises or functional tasks practice prescribed by a professional outside formal therapy sessions is one way of achieving this. It is widely used in community

Background Cardiovascular disease is increased among HIV-infected patients, but little is known regarding ischemic stroke rates. We sought to compare stroke rates and determine stroke risk factors in HIV versus non-HIV patients. Methods An HIV cohort and matched non-HIV comparator cohort seen between 1996 and 2009 were identified from a Boston health care system. The primary endpoint was ischemic stroke, defined using International Classification of Diseases (ICD) codes. Unadjusted stroke incidence rates were calculated. Cox proportional hazards modeling was used to determine adjusted hazard ratios (HR). Results The incidence rate of ischemic stroke was 5.27 per 1000 person years (PY) in HIV compared with 3.75 in non-HIV patients, with an unadjusted HR of 1.40 (95% confidence interval [CI] 1.17-1.69, P<0.001). HIV remained an independent predictor of stroke after controlling for demographics and stroke risk factors (1.21, 1.01-1.46, P=0.043). The relative increase in stroke rates (HIV vs. non-HIV) was significantly higher in younger HIV patients (incidence rate ratio 4.42, 95% CI 1.56-11.09 age 18-29; 2.96, 1.69-4.96 age 30-39; 1.53, 1.06-2.17 age 40-49), and in women (HR 2.16 [1.53-3.04] for women vs. 1.18 [0.95-1.47] for men). Among HIV patients, increased HIV RNA (HR 1.10, 95% CI 1.04-1.17, P=0.001) was associated with an increased risk of stroke. Conclusions Stroke rates were increased among HIV-infected patients, independent of common stroke risk factors, particularly among young patients and women. PMID:22580566

The burden of stroke is increasing in Sub-Saharan Africa (SSA) as the population undergoes epidemiological and demographic transition. Little is known about the nature (risk factors, stroke type and subtype, and causes) of stroke in SSA and whether it differs from stroke in high-income populations. We aimed to compare the nature of stroke between black and white populations in South Africa. We used overlapping sources to ascertain consecutive first-ever-in-a-lifetime stroke patients admitted to Johannesburg Hospital over 23 months. We assessed each patient's demographic details, risk factors, CT confirmed pathological stroke type, ischemic stroke subtype and stroke severity, and compared the nature of stroke between black and white stroke patients. 524 patients with presumed stroke were referred. Of these, 432 were first-ever strokes; 308 patients were black and 76 white. Black patients were significantly younger (mean age 51) than white patients (61). Stroke severity was similar (median NIH stroke score 10; 95% CI 8 to 11). More black than white patients had cerebral hemorrhage (27% versus 15%), lacunar stroke (28% versus 22%) and total anterior circulation infarcts (28% versus 22%). Large vessel atherosclerosis (none detected) and ischemic heart disease were very uncommon (1%) as a cause of stroke in black patients. Hypertension (70% versus 68%) and diabetes (14 versus 15%) were as common in black and white stroke patients, but mean cholesterol levels were lower (4.6 mmol/L; 95% CI 4.3 to 4.9 versus 5.3 mmol/L; 4.8 to 5.7) and cigarette smoking less frequent in black patients (23 versus 54%). Although this was a hospital-based study, the difference in the nature of stroke between black and white stroke patients likely reflects the profile of stroke risk factors. There is an opportunity to prevent an otherwise inevitable increase in atherosclerotic stroke (and IHD) by targeting dietary and smoking habits in the black South African population.

.4% (N.=10) of symptomatic patients and 2.8% (N.=9) of asymptomatic patients. The risk of periprocedural stroke/death was 3.4 times higher in patients with (N.=198) compared to patients without remote ischemic stroke (N.=304) (6.6% versus 2.0% of patients without remote ischemic stroke; P=0.008). Periprocedural stroke/death in symptomatic patients (N.=186) was non-significantly higher in patients with remote ischemic stroke (N.=76) compared with patients without remote ischemic stroke (N.=110) (7.9% versus 3.6%; P=0.206). Asymptomatic patients with remote ischemic stroke (N.=122) had a 5.6-time-higher periprocedural risk of stroke/death compared with asymptomatic patients without remote ischemic stroke (N.=194) (5.7% versus 1.0%; P=0.014). Patients ≥75 years (N.=83) had a 3.0-time-higher periprocedural risk of stroke/death compared with younger patients (N.=419) (8.4% versus 2.9%; P=0.015); a non-significant increase of periprocedural stroke/death was found in both symptomatic (N.=35) and asymptomatic (N.=48) elderly patients (11.4% versus 4.0%, P=0.078; and 6.3% versus 2.4%, P=0.124, respectively). Increased periprocedural risk of stroke/death was not documented in other analyzed patient subgroups. During long-term follow-up, a 1.5-time-higher mortality risk was found in patients with remote ischemic stroke compared with patients without remote ischemic stroke in multivariable analysis; other patient subgroups (except older versus younger patients) did not differ in long-term mortality following carotid stenting. In our experience, all patients with remote pre-procedural any-territory ischemic stroke belong to risky subgroup for periprocedural stroke death after CAS. All asymptomatic patients with remote ischemic stroke should not be treated with CAS. Remote ischemic stroke increases all-cause mortality in long-term follow-up after carotid stenting. Patients aged ≥75 years also have increased risk of periprocedural stroke and death after CAS. These factors should

Background and purpose Identifying embolic strokes of undetermined source (ESUS) patients likely to harbor atrial fibrillation may have diagnostic and therapeutic implications. Our aim was to examine differences between ESUS and cardioembolic strokes, to evaluate stroke recurrence rate among ESUS and to identify baseline characteristics of ESUS patients who were later diagnosed with atrial fibrillation. Materials and methods We assessed all ischemic stroke patients admitted between June 2012 and November 2013. ESUS were compared to cardioembolic strokes at discharge. After at least 12-month follow-up, ESUS patients diagnosed with atrial fibrillation were compared to those who remained as ESUS. Results There were 236 ischemic strokes, 32.6% were ESUS. Compared to cardioembolic strokes, ESUS were younger (p < 0.0001), had milder strokes (p < 0.05), less prevalence of hypertension (p < 0.05), peripheral vascular disease (p < 0.05), and previous ischemic stroke (p < 0.05). After follow-up, 15% of ESUS patients had stroke recurrences and 12% evidenced paroxysmal atrial fibrillation. ESUS patients diagnosed with atrial fibrillation in the follow-up were older (p < 0.0001), had higher erythrocyte sedimentation rate (p < 0.05), and were more likely to have ≥2 infarcts in the same arterial territory in the initial magnetic resonance imaging (p < 0.05). Conclusions Older age, small-scattered infarcts on initial magnetic resonance imaging and high erythrocyte sedimentation rate levels appear to identify ESUS patients more likely to be diagnosed of atrial fibrillation during follow-up.

Lower socioeconomic status (SES) is associated with an increased risk of stroke but the mechanisms are unclear. We aimed to determine whether low-SES stroke/transient ischaemic attack (TIA) patients have a greater burden of vascular risk factors/co-morbidity and reduced health care access. We prospectively studied 467 consecutive stroke and TIA patients from 3 Scottish hospitals (outpatients and inpatients) during 2007/2008. We recorded vascular risk factors, stroke severity, co-morbidity measures, investigations and health service utilisation. SES was derived from postcodes using Scottish Neighbourhood Statistics and analysed in quartiles. TIA/stroke patients in the lowest SES quartile were younger (64 years, SD 14.1) than those in the highest quartile (72 years, SD 12.9; p < 0.0001). They were more likely to be current smokers (42 vs. 22%; p = 0.001) but there was no association with other vascular risk factors/co-morbidity. There was a trend for those with lower SES to have a more severe stroke [modified National Institutes of Health Stroke Scale score and interquartile range: 4 (2-6) vs. 3 (1-5); multivariate p = 0.05]. Lower SES groups were less likely to have neuro-imaging (82 vs. 90%; p = 0.036) or an electrocardiogram (72 vs. 87%; p = 0.003), but differences were no longer significant on multivariate analysis. However, there was equal access to stroke unit care. Low-SES TIA and stroke patients are younger and have a more severe deficit; an increased prevalence of smoking is likely to be a major contributor. We found equal access to stroke unit care for low-SES patients. Copyright © 2010 S. Karger AG, Basel.

To develop effective strategies to address the needs of young patients with stroke, it is important to recognize what components of stroke care they receive. The aims of this study were to describe the provision of stroke care and the factors associated with 3-month mortality and disability (Barthel Index 0-14) in patients younger than 55 years across Western and Eastern Europe. Data from hospital-based stroke registers in Western Europe (7 centers, 6 countries) and Eastern Europe (4 centers, 3 countries) were analyzed. Of 1735 patients admitted to hospital, 201 (11.5%) patients were younger than 55 years (Western European centers 51%, and Eastern European centers 49%). Stroke department care was higher in Western centers (67%) than in Eastern centers (24%) (P < .001). Doctor (P < .001), therapy (P = .01), and nursing (P < .001) time were higher in Western centers. At 3 months, case fatalities between Western and Eastern centers were 8% versus 23% (P = .003). Patients in Eastern European centers were more likely to have disability at 3 months (odds ratio = 24.3, confidence interval = 1.2-494, P = .04). Young patients with stroke in Western Europe are more likely to gain access to a number of components of stroke care compared with those in Eastern Europe. The future challenge is to ensure that recommendations are adopted to ensure all young patients receive evidence-based stroke care across Europe.

To analyse the incidence, risk factors, aetiology, treatment and clinical evolution of young patients with stroke. Retrospective registry of patients aged 55 years or younger hospitalised in a stroke unit during 2014. We recorded the incidence rate for all strokes and analysed demographic data, risk factors, degree of stress, stroke type and aetiology, reperfusion treatments and clinical evolution. The study included 110 patients, the majority of whom were men (60.9%, 1.6:1 ratio). The incidence rate was 13.3% (110 of 830 strokes). Most of the patients had cardiovascular risk factors. Smoking was the most common risk factor (56.4%), followed by arterial hypertension (50%), dyslipidaemia (42.7%), obesity (33%), diabetes (18.2%) and emboligenic heart disease (12.7%). Some 64.3% of the heart disease cases and 51.1% of the dyslipidaemia cases were discovered during hospitalisation. Some 57.2% of the patients experienced psychosocial stress in the stage prior to the stroke. Some 83.6% of the stroke cases were ischaemic, 12.7% were haemorrhagic and 3.6% were venous sinus thrombosis. Of the ischaemic stroke cases, 30.4% were cryptogenic, 23.9% were lacunar, 16.3% were from uncommon causes, 15.2% were atherothrombotic and 14.1% were cardioembolic. Some 78.6% of the cerebral haemorrhage cases were hypertensive. Some 23.3% of the ischaemic stroke cases underwent reperfusion treatments in the acute phase, achieving levels of functional independence at 3 months of 62.5%. The majority of stroke events in patients 55 years of age or younger appear to be related to a high prevalence of classical cardiovascular risk factors and possibly to psychosocial stress.

Geographic variation in stroke rates is well established in the general population, with higher rates in the South than in other areas of the United States. ESRD is a potent risk factor for stroke, but whether regional variations in stroke risk exist among dialysis patients is unknown. Medicare claims from 2000 to 2005 were used to ascertain ischemic stroke events in a large cohort of 265,685 incident dialysis patients. A Poisson generalized linear mixed model was generated to determine factors associated with stroke and to ascertain state-by-state geographic variability in stroke rates by generating observed-to-expected (O/E) adjusted rate ratios for stroke. Older age, female sex, African American race and Hispanic ethnicity, unemployed status, diabetes, hypertension, history of stroke, and permanent atrial fibrillation were positively associated with ischemic stroke, whereas body mass index >30 kg/m(2) was inversely associated with stroke (P<0.001 for each). After full multivariable adjustment, the three states with O/E rate ratios >1.0 were all in the South: North Carolina, Mississippi, and Oklahoma. Regional efforts to increase primary prevention in the "stroke belt" or to better educate dialysis patients on the signs of stroke so that they may promptly seek care may improve stroke care and outcomes in dialysis patients.

The association between atherogenic dyslipidemia and stroke recurrence remains unclear, and may be influenced by different subtypes of ischemic stroke. We aimed to investigate whether atherogenic dyslipidemia contributed to stroke recurrence in ischemic stroke patients and in those with certain subtypes of ischemic stroke. We conducted a prospective hospital-based study enrolling patients with acute ischemic stroke. Atherogenic dyslipidemia was defined as high-density lipoprotein cholesterol <40 mg/dl and triglycerides ≥200 mg/dl. Ischemic stroke subtypes were classified according to the Trial of Org 10172 in Acute Stroke Treatment criteria. The patients were followed up at 3, 6, 12 and 24 months after stroke onset. The association between atherogenic dyslipidemia and stroke recurrence was analyzed by using multivariable Cox regression model. In the 510 ischemic stroke patients, 64 patients (12·5%) had atherogenic dyslipidemia, and 66 patients (12·9%) experienced stroke recurrence events within 24 months. Kaplan-Meier analysis revealed that stroke recurrence rate was significantly higher in patients with atherogenic dyslipidemia than those without in all the stroke patients (20·3% vs. 11·9%; P = 0·048), and more evident in those of large-artery atherosclerosis subtype (31·0% vs. 14·1%; P = 0·014), but not in the other subtypes. Multivariable Cox regression analysis revealed that atherogenic dyslipidemia was associated with higher stroke recurrence risk among stroke patients of large-artery atherosclerosis subtype (hazard ratio, 2·79; 95% confidence interval, 1·24-6·28), but not significant in all the stroke patients (hazard ratio, 1·69; 95% confidence interval, 0·85-3·37). Atherogenic dyslipidemia is associated with higher risk of stroke recurrence in ischemic stroke patients. Such association might be more pronounced in large-artery atherosclerosis subtype and needs further investigation to establish such relationship. © 2015 World

This study was performed to characterize the risk of stroke in elderly patients with recurrent intermittent atrial fibrillation (AF). Although intermittent AF is common, relatively little is known about the attendant risk of stroke. A longitudinal cohort study was performed comparing 460 participants with intermittent AF with 1,552 with sustained AF treated with aspirin in the Stroke Prevention in Atrial Fibrillation studies and followed for a mean of two years. Independent risk factors for ischemic stroke were identified by multivariate analysis. Patients with intermittent AF were, on average, younger (66 vs. 70 years, p < 0.001), were more often women (37% vs. 26% p < 0.001) and less often had heart failure (11% vs. 21%, p < 0.001) than those with sustained AF. The annualized rate of ischemic stroke was similar for those with intermittent (3.2%) and sustained AF (3.3%). In patients with intermittent AF, independent predictors of ischemic stroke were advancing age (relative risk [RR] = 2.1 per decade, p < 0.001), hypertension (RR = 3.4, p = 0.003) and prior stroke (RR = 4.1, p = 0.01). Of those with intermittent AF predicted to be high risk (24%), the observed stroke rate was 7.8% per year (95% confidence interval 4.5 to 14). In this large cohort of AF patients given aspirin, those with intermittent AF had stroke rates similar to patients with sustained AF and similar stroke risk factors. Many elderly patients with recurrent intermittent AF have substantial rates of stroke and likely benefit from anticoagulation. High-risk patients with intermittent AF can be identified using the same clinical criteria that apply to patients with sustained AF.

Abstract There is growing awareness of a link between the gut and cardiovascular disease. Constipation is common among individuals who have had a stroke, and it negatively affects social functioning and quality of life. However, no systematic study on the incidence of constipation in stroke patients has been reported. We selected studies included in Medline, Embase, Cochrane database, and Web of Science. Studies were included if they reported the incidence in stroke patients. Two authors selected the studies, extracted the data independently, and assessed these. Subgroup analyses were conducted according to the stroke subtype and stage of stroke. After detailed evaluations, 8 studies (n  =  1385 participants) were found that contained data that were suitable for meta-analytic synthesis. A forest plot showed that the incidence of constipation was 48% (95% confidence interval [CI]  =  33%–63%). In the analysis of the type of stroke subgroup, the incidence of constipation in patients who had had a hemorrhagic stroke (66% [95% CI  =  40–91%]) was higher than that in patients who had experienced an ischemic stroke (51% [95% CI  =  27%–75%]). The incidence in the acute stage (45% [95% CI  =  36%–54%]) was lower than that in the rehabilitation stage (48% [95% CI  =  23%–73%]). Constipation after a stroke event occurs frequently. This finding may raise awareness about bowel complications to allow correct evaluation and proper management. PMID:28640117

Characteristics of spinal cord stroke in clinical neurology.

Romi, Fredrik; Naess, Halvor

Spinal cord stroke accounts for about 0.3% of all strokes in our department. Thirty-two patients (15 males, 17 females; mean age 63.3 years) treated in the period 1995-2010 were included. Patients underwent thorough investigation including the use of different stroke scales (National Institute of Health Stroke Scale, Barthel Index and modified Rankin Scale). Twenty-eight patients had infarctions, 3 had hemorrhages, and 1 had arterio-venous fistula. Twenty-eight spinal cord strokes were spontaneous, 2 were secondary to aorta aneurysms, and 2 post surgery. Biphasic ictus was seen in 17% of all spontaneous infarctions. Younger age, male gender, hypertension, diabetes mellitus, and higher blood glucose on admission regardless of diabetes mellitus, were risk factors associated with more severe spinal cord stroke. Treatment and prevention of these risk factors should be essential in spinal cord stroke. We recommend a clinical classification into upper (cervical) and lower (thoracic or medullary conus) spinal cord strokes. Patients with upper strokes in this study had more severe strokes initially, but they had a better prognosis. Therefore it is important to identify this patient group.Acute sensory spinal cord deficit symptoms, common initial symptoms in biphasic spinal cord strokes, should be considered as possible spinal cord stroke, especially when preceded by radiating pain between the shoulders.

Stroke Risk Perception in Atrial Fibrillation Patients is not Associated with Clinical Stroke Risk.

Fournaise, Anders; Skov, Jane; Bladbjerg, Else-Marie; Leppin, Anja

2015-11-01

Clinical risk stratification models, such as the CHA2DS2-VASc, are used to assess stroke risk in atrial fibrillation (AF) patients. No study has yet investigated whether and to which extent these patients have a realistic perception of their personal stroke risk. The purpose of this study was to investigate and describe the association between AF patients' stroke risk perception and clinical stroke risk. In an observational cross-sectional study design, we surveyed 178 AF patients with a mean age of 70.6 years (SD 8.3) in stable anticoagulant treatment (65% treatment duration >12 months). Clinical stroke risk was scored through the CHA2DS2-VASc, and patients rated their perceived personal stroke risk on a 7-point Likert scale. There was no significant association between clinical stroke risk assessment and patients' stroke risk perception (rho = .025; P = .741). Approximately 60% of the high-risk patients had an unrealistic perception of their own stroke risk, and there was no significant increase in risk perception from those with a lower compared with a higher risk factor load (χ(2) = .010; P = .522). Considering possible negative implications in terms of lack of motivation for lifestyle behavior change and adequate adherence to the treatment and monitoring of vitamin K antagonist, the apparent underestimation of risk by large subgroups warrants attention and needs further investigation with regard to possible behavioral consequences.

This study compared the functional ability and perceived health status of stroke patients treated by a domiciliary rehabilitation team or by routine hospital-based services after discharge from hospital. Patients discharged from two acute and three rehabilitation hospitals in Nottingham were randomly allocated in three strata (Health Care of the Elderly, General Medical and Stroke Unit) to receive domiciliary or hospital-based care after discharge. Functional recovery was assessed by the Extended Activities of Daily Living (ADL) scale three and six months after discharge and perceived health at six months was measured by the Nottingham Health Profile. A total of 327 eligible patients of 1119 on a register of acute stroke admissions were recruited over 16 months. Overall there were no differences between the groups in their Extended ADL scores at three or six months, or their Nottingham Health Profile scores at six months. In the Stroke Unit stratum, patients treated by the domiciliary team had higher household (p = 0.02) and leisure activity (p = 0.04) scores at six months than those receiving routine care. In the Health Care of the Elderly stratum, death or a move into long-term institutional care at six months occurred less frequently in patients allocated to the routine service, about half of whom attended a geriatric day hospital. Overall there was no difference in the effectiveness of the domiciliary and hospital-based services, although younger stroke unit patients appeared to do better with home therapy while some frail elderly patients might have benefited from day hospital attendance.

Stroke is the leading cause of death in women and the third leading cause in men in France. In young adults (ie, <65 years old), an increase in the incidence of ischemic stroke was observed at a local scale between 1985 and 2011. After the implementation of the 2010 to 2014 National Stroke Action Plan, this study investigates national trends in patients hospitalized by stroke subtypes, in-hospital mortality, and stroke mortality between 2008 and 2014. Hospitalization data were extracted from the French national hospital discharge databases and mortality data from the French national medical causes of death database. Time trends were tested using a Poisson regression model. From 2008 to 2014, the age-standardized rates of patients hospitalized for ischemic stroke increased by 14.3% in patients <65 years old and decreased by 1.5% in those aged ≥65 years. The rate of patients hospitalized for hemorrhagic stroke was stable (+2.0%), irrespective of age and sex. The proportion of patients hospitalized in stroke units substantially increased. In-hospital mortality decreased by 17.1% in patients with ischemic stroke. From 2008 to 2013, stroke mortality decreased, except for women between 45 and 64 years old and for people aged ≥85 years. An increase in cardiovascular risk factors and improved stroke management may explain the increase in the rates of patients hospitalized for ischemic stroke. The decrease observed for in-hospital stroke mortality may be because of recent improvements in acute-phase management. © 2017 American Heart Association, Inc.

Age and type of aphasia in patients with stroke.

PubMed Central

Eslinger, P J; Damasio, A R

1981-01-01

The age and gender of a series of patients with different types of aphasia were analysed. Regardless of gender, patients with Broca and conduction aphasias were significantly younger than those with Wernicke and global aphasias. Considering the established cerebral localisation of each of those aphasia types, it appears that, with age, stroke in the territory of the middle cerebral artery will tend to either shift posteriorly (producing Wernicke aphasia) or occupy most of the middle cerebral artery territory (producing global aphasia). But in the absence of concurrent verification of the locus of lesion in each of the cases in our sample, a possible alternative hypothesis must be entertained: that there might be age-related changes in the neurophysiological mechanism subserving language, such that some types of aphasia would tend to be more prevalent with age, regardless of lesion location.

A patent foramen ovale (PFO) is disproportionately prevalent in patients with cryptogenic stroke. Without alternative explanations, it is frequently considered to be causative. A detailed stratification of these patients may improve the identification of incidental PFO. We investigated the PFO prevalence in 3497 transient ischemic attack and ischemic stroke patients aged 18 to 55 years in the prospective multicenter SIFAP1 study (Stroke in Young Fabry Patients 1) using the ASCO classification. Patients without an obvious cause for transient ischemic attack/stroke (ASCO 0) were divided into subgroups with and without vascular risk factors (ASCO 0+ and 0-). In addition, we looked for PFO-related magnetic resonance imaging lesion patterns. PFO was identified in 25% of patients. Twenty percent of patients with a definite or probable cause of transient ischemic attack/stroke (≥1 grade 1 or 2 ASCO criterion; n=1769) had a PFO compared with 29% of cryptogenic stroke patients (ASCO 0 and 3; n=1728; P<0,001); subdivision of cryptogenic strokes revealed a PFO in 24% of 978 ASCO 3 patients (n.s. versus ASCO 1 and 2) and a higher prevalence of 36% in 750 ASCO 0 cases (P<0.001 versus ASCO 3 and versus ASCO 1 and 2). PFO was more commonly observed in ASCO 0- (n=271) than in ASCO 0+ patients (n=479; 48 versus 29%; P<0.001). There was no PFO-associated magnetic resonance imaging lesion pattern. Cryptogenic stroke patients demonstrate a heterogeneous PFO prevalence. Even in case of less conclusive diseases like nonstenotic arteriosclerosis, patients should preferentially be considered to have a non-PFO-mediated stroke. URL: http://www.clinicaltrials.gov.

High-quality information provision can allow stroke patients to effectively participate in healthcare decision-making, better manage the stroke, and make a good recovery. In this study, we reviewed information needs of stroke patients, methods for providing information to patients, and considerations needed by the information providers. The literature concerning or including information provision for patients with stroke in English was collected from PubMed published from 1990 to 2015. We included all the relevant articles on information provision for stroke patients in English, with no limitation of study design. Stroke is a major public health concern worldwide. High-quality and effective health information provision plays an essential role in helping patients to actively take part in decision-making and healthcare, and empowering them to effectively self-manage their long-standing chronic conditions. Different methods for providing information to patients have their relative merits and suitability, and as a result, the effective strategies taken by health professionals may include providing high-quality information, meeting patients' individual needs, using suitable methods in providing information, and maintaining active involvement of patients. It is suggested that to enable stroke patients to access high-quality health information, greater efforts need to be made to ensure patients to receive accurate and current evidence-based information which meets their individual needs. Health professionals should use suitable information delivery methods, and actively involve stroke patients in information provision.

Little is known as to whether long-term outcomes of acute ischemic stroke (AIS) vary by race/ethnicity. Using the American Heart Association Get With The Guidelines-Stroke registry linked with Medicare claims data set, we examined whether 30-day and 1-year outcomes differed by race/ethnicity among older patients with AIS. We analyzed 200 900 patients with AIS >65 years of age (170 694 non-Hispanic whites, 85.0%; 20 514 non-Hispanic blacks, 10.2%; 6632 Hispanics, 3.3%; 3060 non-Hispanic Asian Americans, 1.5%) from 926 US centers participating in the Get With The Guidelines-Stroke program from April 2003 through December 2008. Compared with whites, other racial and ethnic groups were on average younger and had a higher median score on the National Institutes of Health Stroke Scale. Whites had higher 30-day unadjusted mortality than other groups (white versus black versus Hispanic versus Asian=15.0% versus 9.9% versus 11.9% versus 11.1%, respectively). Whites also had higher 1-year unadjusted mortality (31.7% versus 28.6% versus 28.1% versus 23.9%, respectively) but lower 1-year unadjusted all-cause rehospitalization (54.7% versus 62.5% versus 60.0% versus 48.6%, respectively). After risk adjustment, Asian American patients with AIS had lower 30-day and 1-year mortality than white, black, and Hispanic patients. Relative to whites, black and Hispanic patients had higher adjusted 1-year all-cause rehospitalization (black: adjusted odds ratio, 1.28 [95% confidence interval, 1.21-1.37]; Hispanic: adjusted odds ratio, 1.22 [95% confidence interval, 1.11-1.35]), whereas Asian patients had lower odds (adjusted odds ratio, 0.83 [95% confidence interval, 0.74-0.94]). Among older Medicare beneficiaries with AIS, there were significant differences in long-term outcomes by race/ethnicity, even after adjustment for stroke severity, other prognostic variables, and hospital characteristics.

Treatment of hyperglycaemia in patients with acute stroke.

Castilla-Guerra, L; Fernández-Moreno, M C; Hewitt, J

2016-03-01

The proportion of diabetic patients who are hospitalised for stroke has been increasing in recent years, currently reaching almost a third of all cases of stroke. In addition, about half of patients with acute stroke present hyperglycaemia in the first hours of the stroke. Although hyperglycaemia in the acute phase of stroke is associated with a poor prognosis, its treatment is currently a topic of debate. There is no evidence that the adminstration of intravenous insulin to these patients offers benefits in terms of the evolution of the stroke. New studies in development, such as the SHINE study (Stroke Hyperglycemia Insulin Network Effort), may contribute to clarifying the role of intensive control of glycaemia during the acute phase of the stroke. Ultimately, patients who have presented with stroke should be screened for diabetes. Copyright © 2015 Elsevier España, S.L.U. y Sociedad Española de Medicina Interna (SEMI). All rights reserved.

Many patients experience depression, social isolation and anxiety post stroke. These are associated with a poorer outcome. Ameliorating these problems may improve patient wellbeing. To evaluate the impact of a healthcare worker or volunteer whose multi-dimensional roles have been grouped under the title 'stroke liaison worker'. We searched the Cochrane Stroke Group Trials Register (searched February 2009), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 1, 2009), MEDLINE (1966 to 2009), EMBASE (1980 to 2009) and four other databases. We performed a cited reference search, searched conference proceedings and trials registers, checked reference lists and contacted authors and trial investigators. Randomised controlled trials investigating the impact of a stroke liaison worker versus usual care. We invited trialists to participate in a review of individual patient data. Primary outcomes for patients were subjective health status and extended activities of daily living. Primary outcomes for carers were subjective health status including measures of carer strain. We included 16 trials involving 4759 participants. Analysis did not show a significant overall difference for subjective health status (standardised mean difference (SMD) -0.03, 95% confidence interval (CI) -0.11 to 0.04, P = 0.34) or extended activities of daily living (SMD 0.04, 95% CI -0.03 to 0.11, P = 0.22). There was no overall significant effect for the outcome of carer subjective health status (SMD 0.04, 95% CI -0.05 to 0.14, P = 0.37). Patients with mild to moderate disability (Barthel 15 to 19) had a significant reduction in dependence (odds ratio (OR) 0.62, 95% CI 0.44 to 0.87, P = 0.006). This would equate to 10 fewer dependent patients (95% CI 17 fewer to 4 fewer) for every 100 patients seen by the stroke liaison worker. Similar results were seen for the outcome of death or dependence for the subgroup with Barthel 15 to 19 (OR 0.55, 95% CI 0.38 to 0.81, P

Diabetes mellitus is associated with post-stroke cognitive impairment. To the best of our knowledge, no study has explored the relationship between prediabetes and post-stroke cognitive impairment. The purpose of this study is to explore the association between prediabetes and cognitive impairment in ischaemic stroke patients at 1 month. Two hundred one acute ischaemic stroke patients were consecutively recruited within the first 24 h after admission and were followed up for 1 month. Patients were divided into a diabetes mellitus group, prediabetes group and non-diabetes mellitus group by fasting glucose levels, 2-h postprandial blood glucose levels and glycosylated haemoglobin levels at admission. Cognitive function was evaluated by the Mini-Mental State Examination at 1 month after stroke. The prediabetes group had a higher risk of post-stroke cognitive impairment than the non-diabetes group (35.7% vs. 18.1%, χ 2  = 4.252, P = .039). In logistical analyses, prediabetes was associated with post-stroke cognitive impairment after adjusting for potential confounding factors (odds ratio 3.062, 95% confidence interval 1.130-8.299, P = .028). Our findings show that prediabetes is associated with post-stroke cognitive impairment and may predict its development at 1 month post-stroke. Copyright © 2018 Elsevier B.V. All rights reserved.

To compare cases of poisoning according to age to detect differences in frequency of visits to the emergency department, patient characteristics, case management, and immediate outcome in terms of related mortality. Descriptive study of a retrospective series of patients who visited a university hospital emergency department for treatment of poisoning between 2009 and 2014. We collected patient characteristics and data related to the event, case management, and poisoning-related death. Patients were grouped according to age (cut-off 65 y). Of a total of 3847 poisoning episodes, 341 (8.9%) were in patients aged 65 years or older. The percentage of women among these older patients (61.3%) was greater than among younger patients (36.3%; P<.001). Poisoning was accidental in older patients more often than younger ones (64.4% vs 9.5%, respectively; P<.001), occurred more often in the home (82.1% vs 37%, P<.001), and more often required active treatment (73.3% vs 57.4%; P<.001) and admission to hospital (21.4% vs 7.3%, P<.001). The related mortality rate was also higher in the older patients (2.1% vs 0.1% in younger patients, P<.001). The percentage of poisonings in patients aged 65 years or older is not negligible. Poisoning in patients of advanced age tends to be accidental and take place in the home. Older patients more often require active treatment and hospital admission; poisoning-related death is more common in older patients than younger ones.

Stroke recurrence and disability in patients with a minor stroke is one of the most depressing medical situations. In this study, we aimed to identify which factors were associated with adverse outcomes of a minor stroke. The China National Stroke Registry (CNSR) is a nationwide prospective registry for patients presented to hospitals with acute cerebrovascular events between September 2007 and August 2008. The 3-month follow-up was completed in 4669 patients with a minor stroke defined as the initial neurological severity lower than 4 in the National Institutes of Health Stroke Scale (NIHSS). Multivariate model was used to determine the association between risk factors and clinical outcomes. Of 4669 patients with a minor stroke during 3-month follow-up, 459 (9.8 %) patients experienced recurrent stroke, 679 (14.5 %) had stroke disability and 168 (3.6 %) died. Multivariate model identified hypertension, diabetes mellitus, atrial fibrillation, coronary heart disease and previous stroke as independent predictors for the recurrent stroke. Age, diabetes mellitus, atrial fibrillation, previous stroke and time from onset to admission < 24 h were independent predictors for stroke disability. The independent predictors for the all-caused death were age, atrial fibrillation, and coronary heart disease. The short-term risk of poor clinical outcome in Chinese patients with a minor stroke was substantial. Therefore, patients with a minor stroke should be given expeditious assessment and urgent aggressive intervention.

Sickle-cell anaemia is the severe homozygotic form of drepanocytosis, a genetic disorder that often occurs among black people and which is characterised by the production of haemoglobin S, chronic hemolytic anaemia and tissue ischaemia due to alterations in blood flow. A quarter of the patients presented neurological manifestations; 8-10% of children will have a stroke. AIM. To analyse the cases of stroke in children with sickle-cell anaemia in our centre. We conducted a retrospective descriptive study of children with sickle-cell anaemia and stroke. Five patients (two Dominicans and three Guineans) with sickle-cell anaemia and stroke; one patient suffered two episodes of stroke. The mean age was 27 months. Five of the episodes were ischaemic infarctions. Stroke was the initial form of presentation of drepanocytosis on three occasions. Two of the strokes occurred within a context of pneumococcal meningitis. Four of the patients had previously reported fever. The initial clinical picture was hemiparesis in four cases. Mean haemoglobin on diagnosing the stroke was 6.5 g/dL. Transcranial ultrasound imaging revealed alterations in three patients and, in all the patients, magnetic resonance imaging revealed lesions, which were bilateral in half the cases. Following the stroke, a hypertransfusion regimen protocol was established and only one patient presented a new stroke. This same patient went on to develop moya-moya disease and was submitted to an indirect revascularisation; the patient progressed well, without presenting any new ischaemic events. Drepanocytosis is a disease that is emerging in our setting as a result of immigration. It should be suspected in cases of paediatric strokes associated to anaemia, above all in black children under the age of five who were not submitted to neonatal screening.

At our hospital, door-to-imaging time is comprised of 2 time periods: the time before a stroke is recognized, followed by the period after the stroke code is called during which the stroke team assesses and brings the patient to the computed tomography scanner. To control for delays due to triage, we isolated the time period after a potential stroke has been recognized, as few studies have examined the biases of stroke code responders. This "code-to-imaging time" (CIT) encompassed the time from stroke code activation to initial imaging, and we hypothesized that perception of stroke severity would affect how quickly stroke code responders act. In consecutively admitted ischemic stroke patients at The Mount Sinai Hospital emergency department, we tested associations between National Institutes of Health Stroke Scale scores (NIHSS), continuously and at different cutoffs, and CIT using spline regression, t tests for univariate analysis, and multivariable linear regression adjusting for age, sex, and race/ethnicity. In our study population, mean CIT was 26 minutes, and mean presentation NIHSS was 8. In univariate and multivariate analyses comparing CIT between mild and severe strokes, stroke scale scores <4 were associated with longer response times. Milder strokes are associated with a longer CIT with a threshold effect at a NIHSS of 4.

The safety and outcomes of intravenous thrombolysis (IVT) to stroke patients via telestroke (TS) is similar to those presenting to stroke centers. Little is known on the accuracy of TS diagnosis among those receiving IVT. We sought to compare the rate of patients receiving IVT with diagnosis of ischemic stroke as opposed to stroke mimic (SM) in our TS network to those who presented to our comprehensive stroke center (CSC). Consecutive patients receiving IVT between August 2014 and June 2015 were identified at our CSC and TS network. We compared rates of SM, post-IVT symptomatic intracerebral hemorrhage (sICH), in-hospital mortality, and discharge destination. We evaluated 131 receiving IVT were included in the analysis. Rates of SM receiving IVT were similar (CSC 12% versus 7% TS, p=0.33). Four stroke patients experienced sICH or in-hospital mortality; neither were found among SM patients. Discharge destination was similar between stroke and SM patients (p=0.9). SM patients had higher diagnoses of migraine (p=0.05) and psychiatric illness (p<0.01). The accuracy of diagnosing stroke in IVT-eligible patients evaluated via TS is similar to evaluations at our CSC. Continued efforts should be made to minimize exposure of SM patients to IVT in both settings. Copyright © 2016 Elsevier B.V. All rights reserved.

  Dementia is a frequent condition after stroke that may affect the prognosis of patients. Our aim was to determine whether post-stroke dementia was a predictor of 1-year case-fatality and to evaluate factors that could influence survival in demented stroke patients. From 1985 to 2008, all first-ever strokes were recorded in the population-based stroke registry of Dijon, France (150, 000 inhabitants). Dementia was diagnosed during the first month following stroke, according to DSM-III and DSM-IV criteria. Survival was evaluated at 1 year and multivariate analyses were performed using Cox proportional hazards to identify independent predictive factors.   We recorded 3948 first-ever strokes. Among these stroke patients, 3201 (81%) were testable, and of these, 653 (20.4%) had post-stroke dementia (337 women and 316 men). Demented patients had lower 1-year survival than patients without dementia (82.9% vs. 86.9%, P = 0.013). However, in multivariate analysis, dementia did not appear as an independent predictor of 1-year death. In demented stroke patients, age >80 years old, severe handicap at discharge, recurrent stroke within the first year and subarachnoid haemorrhage were associated with a higher risk of 1-year death, and the risk was lower in the study period 2003-2008.   Dementia after stroke is not independently associated with an increased risk of death at 1 year. In recent years, 1-year case-fatality decreased in demented as well as in and non-demented patients suggesting that improvements in the management of stroke also benefited the most fragile patients. © 2011 The Author(s).

Background Infections are known to be a major complication of stroke patients. In this study, we evaluated the risk of community-acquired bacteriuria among stroke patients, the associated factors, and the causative organisms. Methods This was a cross-sectional study involving 70 stroke patients and 83 age- and sex-matched, apparently healthy controls. Urine specimens were collected from all the study subjects and were analyzed by standard microbiological methods. Demographic and clinical information was also collected from the study subjects. For stroke patients, the information collected also included stroke parameters, such as stroke duration, frequency, and subtype. Results Bacteriuria was significantly higher among stroke patients (24.3%, n=17) than among the control group (7.2%, n=6), with a relative risk of 3.36 (confidence interval [CI], 1.40–8.01, P=0.006). Among the control group, all six bacteriuria cases were asymptomatic, whereas the 17 stroke bacteriuria cases comprised 15 cases of asymptomatic bacteriuria and two cases of symptomatic bacteriuria. Female sex (OR, 3.40; CI, 1.12–10.30; P=0.03) and presence of stroke (OR, 0.24; CI, 0.08–0.70; P=0.009) were significantly associated with bacteriuria. The etiology of bacteriuria was similar in both study groups, and coagulase-negative Staphylococcus spp. were the most predominant organisms isolated from both stroke patients (12.9%) and the control group (2.4%). Conclusion Stroke patients in the study region have a significantly higher risk of community-acquired bacteriuria, which in most cases is asymptomatic. Community-acquired bacteriuria in stroke patients appears to have little or no relationship with clinical parameters of stroke such as stroke subtype, duration and frequency. PMID:27051289

Family support and patient satisfaction with treatment are crucial for aiding in the recovery from stroke. However, current validated stroke-specific questionnaires may not adequately capture the impact of these two variables on patients undergoing clinical trials of new drugs. Therefore, the aim of this study was to develop and evaluate a new stroke patient-reported outcome measure (Stroke-PROM) instrument for capturing more comprehensive effects of stroke on patients participating in clinical trials of new drugs. A conceptual framework and a pool of items for the preliminary Stroke-PROM were generated by consulting the relevant literature and other questionnaires created in China and other countries, and interviewing 20 patients and 4 experts to ensure that all germane parameters were included. During the first item-selection phase, classical test theory and item response theory were applied to an initial scale completed by 133 patients with stroke. During the item-revaluation phase, classical test theory and item response theory were used again, this time with 475 patients with stroke and 104 healthy participants. During the scale assessment phase, confirmatory factor analysis was applied to the final scale of the Stroke-PROM using the same study population as in the second item-selection phase. Reliability, validity, responsiveness and feasibility of the final scale were tested. The final scale of Stroke-PROM contained 46 items describing four domains (physiology, psychology, society and treatment). These four domains were subdivided into 10 subdomains. Cronbach's α coefficients for the four domains ranged from 0.861 to 0.908. Confirmatory factor analysis supported the validity of the final scale, and the model fit index satisfied the criterion. Differences in the Stroke-PROM mean scores were significant between patients with stroke and healthy participants in nine subdomains (P < 0.001), indicating that the scale showed good responsiveness.

Stroke is the 4th leading cause of death and 1st leading cause of disability in Singapore. However the information on long-term post stroke outcomes for Singaporean patients was limited. This study aimed to investigate the post stroke outcomes of 5-year survival and rehospitalization due to stroke recurrence for hemorrhagic and ischemic stroke patients in Singapore. The outcomes were stratified by age, ethnic group, gender and stroke types. The causes of death and stroke recurrence were also explored in the study. A multi-site retrospective cohort study. Patients admitted for stroke at any of the three hospitals in the National Healthcare Group of Singapore were included in the study. All study patients were followed up to 5 years. Kaplan-Meier was applied to study the time to first event, death or rehospitalization due to stroke recurrence. Cox proportional hazard model was applied to study the time to death with adjustment for stroke type, age, sex, ethnic group, and admission year. Cumulative incidence model with competing risk was applied for comparing the risks of rehospitalization due to stroke recurrence with death as the competing risk. Totally 12,559 stroke patients were included in the study. Among them, 59.3% survived for 5 years; 18.4% were rehospitalized due to stroke recurrence in 5 years. The risk of stroke recurrence and mortality increased with age in all stroke types. Gender, ethnic group and admitting year were not significantly associated with the risk of mortality or stroke recurrence in hemorrhagic stroke. Male or Malay patient had higher risk of stroke recurrence and mortality in ischemic stroke. Hemorrhagic stroke had higher early mortality while ischemic stroke had higher recurrence and late mortality. The top cause of death among died stroke patients was cerebrovascular diseases, followed by pneumonia and ischemic heart diseases. The recurrent stroke was most likely to be the same type as the initial stroke among rehospitalized stroke

Studies of racial/ethnic variations in stroke rarely consider the South Asian population, one of the fastest growing sub-groups in the United States. This study compared risk factors for stroke among South Asians with those for whites, African-Americans, and Hispanics. Data on 3290 stroke patients were analyzed to examine risk differences among the four racial/ethnic groups. Data on 3290 patients admitted to a regional stroke center were analyzed to examine risk differences for ischemic stroke (including subtypes of small and large vessel disease) among South Asians, whites, African Americans and Hispanics. South Asians were younger and had higher rates of diabetes mellitus, blood pressure, and fasting blood glucose levels than other race/ethnicities. Prevalence of diabetic and antiplatelet medication use, as well as the incidence of small-artery occlusion ischemic stroke was also higher among South Asians. South Asians were almost a decade younger and had comparable socioeconomic levels as whites; however, their stroke risk factors were comparable to that of African Americans and Hispanics. Observed differences in stroke may be explained by dietary and life style choices of South Asian-Americans, risk factors that are potentially modifiable. Future population and epidemiologic studies should consider growing ethnic minority groups in the examination of the nature, outcome, and medical care profiles of stroke.

As stroke in young adults is assumed to have different etiologies and risk factors than in older populations, the aim of this study was to examine the contribution of established potentially modifiable cardiovascular risk factors to the burden of stroke in young adults. A German nationwide case-control study based on patients enrolled in the SIFAP1 study (Stroke In Young Fabry Patients) 2007 to 2010 and controls from the population-based GEDA study (German Health Update) 2009 to 2010 was performed. Cases were 2125 consecutive patients aged 18 to 55 years with acute first-ever stroke from 26 clinical stroke centers; controls (age- and sex-matched, n=8500, without previous stroke) were from a nationwide community sample. Adjusted population-attributable risks of 8 risk factors (hypertension, hyperlipidemia, diabetes mellitus, coronary heart disease, smoking, heavy episodic alcohol consumption, low physical activity, and obesity) and their combinations for all stroke, ischemic stroke, and primary intracerebral hemorrhage were calculated. Low physical activity and hypertension were the most important risk factors, accounting for 59.7% (95% confidence interval, 56.3-63.2) and 27.1% (95% confidence interval, 23.6-30.6) of all strokes, respectively. All 8 risk factors combined explained 78.9% (95% confidence interval, 76.3-81.4) of all strokes. Population-attributable risks of all risk factors were similar for all ischemic stroke subtypes. Population-attributable risks of most risk factors were higher in older age groups and in men. Modifiable risk factors previously established in older populations also account for a large part of stroke in younger adults, with 4 risk factors explaining almost 80% of stroke risk.

Cerebrovascular complications are often the first cause of hospitalization in patients with Fabry disease (FD). Screenings for FD among stroke patients have yielded discrepant results, likely as a result of heterogeneous or incomplete assessment. We designed a study to identify FD among adults 60 years of age or younger who were consecutively admitted for acute ischemic stroke or transient ischemic attack (TIA) to a stroke neurology service in Italy. Patients with first-ever or recurrent events were included, irrespective of gender, risk factors, or stroke type. We screened male patients using α-galactosidase A enzyme assay, and female patients using DNA sequencing. FD was eventually established after a broad multidisciplinary discussion. We screened 108 patients (61% males, median age: 48 years); 84% of these patients had stroke. De novo FD diagnosis was established in 3 patients (2.8%; 95% confidence interval, .57-8.18): a 59-year-old man with recurrent lacunar-like strokes and multiple risk factors; a 42-year-old woman with recurrent cryptogenic minor strokes; and a 32-year-old woman with recurrent strokes previously attributed to Behçet's disease. Screened patients were systematically asked for typical FD symptoms; each of the de novo patients reported one or more of the following: episodes of hand/foot pain during fever, angiokeratoma, and family history of heart disease. In all of the patients events were recurrent, and lacunar-like infarcts characterized their brain imaging. Prevalence of FD among nonselected adults 60 years of age or younger with acute ischemic stroke or TIA is not negligible. A systematic search for FD in a stroke setting, using a comprehensive clinical, biochemical, and genetic screening protocol, may be worthwhile. Copyright © 2015 National Stroke Association.

2018-05-01

A significant proportion of patients with acute stroke symptoms have an alternative 'mimic' diagnosis. A narrative review was carried out to explore the frequency, characteristics and aetiology of stroke mimics. Prehospital and thrombolysis-treated patients were described separately. Overall, 9972 studies were identified from the initial search and 79 studies were included with a median stroke mimic rate of 19% (range: 1-64%). The prehospital median was 27% (range: 4-43%) and the thrombolysis median 10% (range: 1-25%). Seizures, migraines and psychiatric disorders are the most frequently reported causes of stroke mimics. Several characteristics are consistently associated with stroke mimics; however, they do not fully exclude the possibility of stroke. Nineteen per cent of suspected stroke patients had a mimic condition. Stroke mimics were more common with younger age and female sex. The range of mimic diagnoses, a lack of clear differentiating characteristics and the short treatment window for ischaemic stroke create challenges for early identification.

Current literature provides mixed evidence on disparities by race/ethnicity and socioeconomic status in discharge outcomes after hospitalization for acute ischemic stroke. Using comprehensive data from 8 states, we sought to compare inpatient mortality and length of stay by race/ethnicity and socioeconomic status. We examined all 2007 hospitalizations for acute ischemic stroke in all nonfederal acute care hospitals in Arizona, California, Florida, Maine, New Jersey, New York, Pennsylvania, and Texas. Population was stratified by race/ethnicity (non-Hispanic whites, non-Hispanic blacks, and Hispanics) and socioeconomic status, measured by median income of patient zip code. For each stratum, we estimated risk-adjusted rates of inpatient mortality and longer length of stay (greater than median length of stay). We also compared the hospitals where these subpopulations received care. Hispanic and black patients accounted for 14% and 12% of all ischemic stroke admissions (N=147 780), respectively, and had lower crude inpatient mortality rates (Hispanic=4.5%, blacks=4.4%; all P<0.001) compared with white patients (5.8%). Hispanic and black patients were younger and fewer had any form of atrial fibrillation. Adjusted for patient risk, inpatient mortality was similar by race/ethnicity, but was significantly higher for low-income area patients than that for high-income area patients (odds ratio, 1.08; 95% confidence interval, 1.02-1.15). Risk-adjusted rates of longer length of stay were higher among minority and low-income area populations. Risk-adjusted inpatient mortality was similar among patients by race/ethnicity but higher among patients from lower income areas. However, this pattern was not evident in sensitivity analyses, including the use of mechanical ventilation as a partial surrogate for stroke severity.

Brain stroke is the main cause of disability starting from age of 40 years. Due to this disability, a person loses his ability to work because of long-lasting disorders of biosocial functions. According to literature, occupational therapy for such patients, taking regard to their social, cultural and economic background, significantly increases their self-care and independence and helps to educate working skills. OBJECTIVE. To evaluate conditional disorders of patients with stroke under rehabilitation and to establish the influence of extent of brain damage, localization, age and gender on effectiveness of occupational therapy. Study included 47 men and 53 women diagnosed with brain ischemia or hemorrhage (ischemic or hemorrhagic stroke). Out of them, 30 were of working age (18-59 years old) and 70 of non-working age (more than 60 years old). The mean age was 63.4+/-1.2 years. In order to assess the functional status of patients, they were tested using the Functional Independence Measure (FIM). At the start of rehabilitation, the mean FIM score was 47.4+/-16.1 (48.9+/-15.6 for men and 46.3+/-16.6 for women, p>0.05). At the end of early rehabilitation, the mean FIM score reached up to 89.9+/-22.3 (94.7+/-18.9 for men and 85.7+/-24.3 for women, p<0.05). Evaluation of functional status showed that at the start of rehabilitation functional status was worse in women than men, nevertheless, women's functional status improved during rehabilitation, though the difference between men and women still remained. Occupational therapy was less effective for patients who suffered from hemiplegia than for patients with hemiparesis (p<0.01). Older patients (more than 60 years) had more expressed functional disorders, and worse functional recovery comparing with younger, working age patients (18-59 years old). Evaluation of occupational therapy effectiveness at the end of early rehabilitation showed that extent of brain damage influences independence of patients suffering from brain

Dementia and stroke are major causes of disability in the elderly. However, the association between pre-stroke dementia and functional outcome after stoke remains unresolved. We aimed to determine this association in patients with acute ischemic stroke. Among patients registered in the Fukuoka Stroke Registry from June 2007 to May 2015, 4,237 patients with ischemic stroke within 24 h of onset, who were functionally independent before the onset, were enrolled in this study. Pre-stroke dementia was defined as any type of dementia that was present prior to the index stroke. Primary and secondary study outcomes were poor functional outcome (modified Rankin Scale 3-6) at 3 months after the stroke onset and neurological deterioration (≥2-point increases on the National Institutes of Health Stroke Scale score during hospitalization), respectively. For propensity score (PS)-matched cohort study to control confounding variables for pre-stroke dementia, 318 pairs of patients with and without pre-stroke dementia were also selected on the basis of 1:1 matching. Multivariable logistic regression models and conditional logistic regression analysis were used to quantify associations between pre-stroke dementia and study outcomes. Of all 4,237 participants, 347 (8.2%) had pre-stroke dementia. The frequencies of neurological deterioration and poor functional outcome were significantly higher in patients with pre-stroke dementia than in those without pre-stroke dementia (neurological deterioration, 16.1 vs. 7.1%, p < 0.01; poor functional outcome, 63.7 vs. 27.1%, p < 0.01). Multivariable analysis showed that pre-stroke dementia was significantly associated with neurological deterioration (OR 1.67; 95% CI 1.14-2.41; p < 0.01) and poor functional outcome (OR 2.91; 95% CI 2.17-3.91; p < 0.01). In the PS-matched cohort study, the same trends were observed between the pre-stroke dementia and neurological deterioration (OR 2.60; 95% CI 1.17-5.78; p < 0.01) and between the dementia and

Background: Unlike the western hemisphere, information about stroke epidemiology in southern Iran is scarce. The aim of this study was to determine the main epidemiological characteristics of patients with stroke and its mortality rate in southern Iran. Methods: A retrospective, single-center, hospital-based longitudinal study was performed at Nemazee Hospital in Shiraz, Southern Iran. Patients with a diagnosis of hemorrhagic and ischemic strokes were identified based on the International Classification of Diseases, 9th and 10th editions, for the period between 2001 and 2010. Demographics including age, sex, area of residence, socioeconomic status, length of hospital stay, and discharge destinations were analyzed in association with mortality. Results: 16351 patients with a mean age of 63.4 years (95% CI: 63.1, 63.6) were included in this analysis. Men were slightly predominant (53.6% vs. 46.4%). Forty-seven percent of the total sample was older than 65,17% were younger than 45, and 2.6% were children younger than 18. The mean hospital stay was 6.3 days (95% CI: 6.2, 6.4). Among all types of strokes, the overall hospital mortality was 20.5%. Multiple logistic regression revealed significantly higher in-hospital mortality in women and children (P<0.001) but not in patients with low socioeconomic status or from rural areas. During the study period, the mortality proportions increased from 17.8% to 22.2%. Conclusion: In comparison to western countries, a larger proportion of our patients were young adults and the mortality rate was higher. PMID:24293785

Objectives To determine which early modifiable factors are associated with younger stroke survivors' ability to return to paid work in a cohort study with 12-months of follow-up conducted in 20 stroke units in the Stroke Services NSW clinical network. Participants Were aged >17 and <65 years, recent (within 28 days) stroke, able to speak English sufficiently to respond to study questions, and able to provide written informed consent. Participants with language or cognitive impairment were eligible to participate if their proxy provided consent and completed assessments on the participants' behalf. The main outcome measure was return to paid work during the 12 months following stroke. Results Of 441 consented participants (average age 52 years, 68% male, 83% with ischemic stroke), 218 were in paid full-time and 53 in paid part-time work immediately before their stroke, of whom 202 (75%) returned to paid part- or full-time work within 12 months. Being male, female without a prior activity restricting illness, younger, independent in activities of daily living (ADL) at 28 days after stroke, and having private health insurance was associated with return to paid work, following adjustment for other illnesses and a history of depression before stroke (C statistic 0·81). Work stress and post stroke depression showed no such independent association. Conclusions Given that independence in ADL is the strongest predictor of return to paid work within 12 months of stroke, these data reinforce the importance of reducing stroke-related disability and increasing independence for younger stroke survivors.

The authors assessed patients with acute stroke to determine whether the systematic use of brief screening measures would more efficiently detect cognitive and sensory impairment than standard clinical practice. Fifty-three patients admitted to an acute stroke unit were assessed within 10 days of stroke onset. Performance on the screening measures was compared to information obtained from review of the patient's chart at discharge. Cognition, language, visual acuity, visual-spatial neglect, hearing, and depression were evaluated. Formal screening detected significantly more impairments than were noted in patient charts in every domain. Only 3 patients had no impairments identified on screening; all remaining patients had at least 1 impairment detected by screening that was not documented in the chart. Thirty-five percent had 3 or more undetected impairments. Memory impairment was most likely to be noted in the chart; for all other domains tested, undocumented impairment ranged from 61% (neglect) to 97% (anomia). Many acute stroke patients had cognitive and perceptual deficits that were not documented in their charts. These data support the Post-Stroke Rehabilitation Guidelines for systematic assessment even when deficits are not immediately apparent. Systematic screening may improve discharge planning, rehabilitation treatment, and long-term outcome of persons with stroke.

Warfarin for stroke prevention in octogenarians with atrial fibrillation.

2001-01-01

The authors examined warfarin use in elderly patients with atrial fibrillation. Medical records were abstracted from a random sample of Medicare beneficiaries with atrial fibrillation who were discharged from Kansas hospitals. Data were analyzed for warfarin and aspirin use and risk factors for stroke or bleeding in patients 65-79 years of age or 80 years and older. Stroke risk factors other than age and atrial fibrillation were seen in 98% of 142 patients less than 80 years of age and 100% of 141 octogenarians. Warfarin use was similar in the younger and older age groups (50% vs. 45%, respectively; p = ns) and was not associated with the number of stroke or bleeding risk factors. Compared to patients less than 80 years of age, octogenarians were less likely to receive aspirin (38% vs. 27%, respectively; p < 0.05). Anticoagulation rates for high-risk patients with atrial fibrillation were low and poorly explained by stroke or bleeding risks.

Stroke patients' involvement in the rehabilitation process including decision making has made significant advances clinically over the past two decades. However, development of patient-focused interventions in stroke rehabilitation is a relatively under developed area of research. The aim of this study was to interpret the explanations that patients gave of their experience after stroke and how these may validate an already established patient-focused intervention framework - the Quest for quality and improved performance (QQUIP) (2006) that includes seven quality improvement goals. A random purposive sample of eight stroke patients was interviewed between 3 and 6 months following discharge. Patients' reports of their experience after stroke were obtained using in-dept semi-structured interviews and analysed using Qualitative Content Analysis. Explanations given by patients included both positive and negative reports of the stroke experience. Regardless of consequences as a result of physical, psychological and social impairments, there were other life style disruptions that were reported by all patients such as taking new medication and adverse effects of these, experiencing increasing fatigue, difficulties with social activities and situations and having to make changes in health behaviours and lifestyle. Some of the core themes that emerged reflected the aims of QQUIP improvement goals that include improving health literacy, clinical decision-making, self-care, patient safety, access to health advice, care experience and service development. Further recommendations based on the findings from this study would be to consider using the QQUIP framework for developing intervention studies in stroke rehabilitation care that are person-centred. This framework provides a template that is equipped to address some of the main concerns that people have following the experience of stroke and also focuses on improving quality of care.

Improving pain assessment and managment in stroke patients

Stroke patients can experience a variety of pain. Many stroke patients have co-morbidities such as osteoporosis, arthritis or diabetes causing diabetic neuropathy. As well as pain from other long term conditions, stroke patients can experience central post-stroke pain, headaches, and musculoskeletal issues such as hypertonia, contractures, spasticity, and subluxations. These stroke patients can also have communication difficulties in the form of expressive dysphasia and/or global aphasia. Communication difficulties can result in these patients not expressing their pain and therefore not having it assessed, leading to inadequate pain relief that could impact their rehabilitation and recovery. By implementing an observational measurement of pain such as the Abbey pain scale, patients with communication difficulties can have their pain assessed and recorded. Initially 30% of patients on the acute stroke ward did not have their pain assessed and adequately recorded and 15% of patients had inadequate pain relief. The patient was assessed if they were in pain and therefore not receiving adequate pain relief by measuring their pain on the Abbey pain scale. After introducing the Abbey pain scale and creating a nurse advocate, an improvement was shown such that only 5% of patients did not have their pain recorded and all had adequate pain relief.

Stroke patients can experience a variety of pain. Many stroke patients have co-morbidities such as osteoporosis, arthritis or diabetes causing diabetic neuropathy. As well as pain from other long term conditions, stroke patients can experience central post-stroke pain, headaches, and musculoskeletal issues such as hypertonia, contractures, spasticity, and subluxations. These stroke patients can also have communication difficulties in the form of expressive dysphasia and/or global aphasia. Communication difficulties can result in these patients not expressing their pain and therefore not having it assessed, leading to inadequate pain relief that could impact their rehabilitation and recovery.

Background and purpose Hospital costs associated with atrial fibrillation (AFib) among stroke patients have not been well-studied, especially among people younger than 65 years. We estimated the AFib-associated hospital costs in U.S. patients aged 18-64 years. Methods We identified hospital admissions with a primary diagnosis of ischemic stroke from the 2010-2012 MarketScan Commercial Claims and Encounters inpatient datasets, excluding those with capitated health insurance plans, aged <18 or >64, missing geographic region, hospital costs below the 1st or above 99th percentile, and having carotid intervention (N=40,082). We searched the data for AFib and analyzed the costs for non-repeat and repeat stroke admissions separately. We estimated the AFib-associated costs using multivariate regression models controlling for age, sex, geographic region, and Charlson comorbidity index. Results Of the 33,500 non-repeat stroke admissions, 2,407 (7.2%) had AFib. Admissions with AFib cost $4,991 more than those without AFib ($23,770 vs. $18,779). For the 6,582 repeat stroke admissions, 397 (6.0%) had AFib. The costs were $3,260 more for those with AFib than those without ($24,119 vs. $20,929). After controlling for potential confounders, AFib-associated costs for non-repeat stroke admissions were $4,905, representing 20.6% of the total costs for the admissions. Both the hospital costs and the AFib-associated costs were associated with age, but not sex. AFib-associated costs for repeat stroke admissions were not significantly higher than for non-AFib patients, except for those aged 55-64 ($3,537). Conclusions AFib increased the hospital cost of ischemic stroke substantially. Further investigation on AFib-associated costs for repeat stroke admissions is needed. PMID:25851767

Background and objectives Stroke is common in patients undergoing long-term dialysis, but the implications for mortality after stroke in these patients are not fully understood. Design, setting, participants, & measurements A large cohort of dually-eligible (Medicare and Medicaid) patients initiating dialysis from 2000 to 2005 and surviving the first 90 days was constructed. Medicare claims were used to ascertain ischemic and hemorrhagic strokes occurring after 90-day survival. A semi-Markov model with additive hazard extension was generated to estimate the association between stroke and mortality, to calculate years of life lost after a stroke, and to determine whether race was associated with differential survival after stroke. Results The cohort consisted of 69,371 individuals representing >112,000 person-years of follow-up. Mean age±SD was 60.8±15.5 years. There were 21.1 (99% confidence interval [99% CI], 20.0 to 22.3) ischemic strokes and 4.7 (99% CI, 4.2 to 5.3) hemorrhagic strokes after cohort entry per 1000 patient-years. At 30 days, mortality was 17.9% for ischemic stroke and 53.4% for hemorrhagic stroke. The adjusted hazard ratio (AHR) depended on time since entry into the cohort; for patients who experienced a stroke at 1 year after cohort entry, for example, the AHR of hemorrhagic stroke for mortality was 25.4 (99% CI, 22.4 to 28.4) at 1 week, 9.9 (99% CI, 8.4 to 11.6) at 3 months, 5.9 (99% CI, 5.0 to 7.0) at 6 months, and 1.8 (99% CI, 1.5 to 2.1) at 24 months. The corresponding AHRs for ischemic stroke were 11.7 (99% CI, 10.2 to 13.1) at 1 week, 6.6 (99% CI, 6.4 to 6.7) at 3 months, and 4.7 (99% CI, 4.5 to 4.9) at 6 months, remaining significantly >1.0 even at 48 months. Median months of life lost were 40.7 for hemorrhagic stroke and 34.6 for ischemic stroke. For both stroke types, mortality did not differ by race. Conclusions Dialysis recipients have high mortality after a stroke with corresponding decrements in remaining years of life. Poststroke

Caregiver burden in dementia is an important issue, but few studies have examined the mental health of younger and older family caregivers by comparing them with age- and gender-matched community residents. We aimed to compare the mental health of dementia caregivers with that of community residents and to clarify factors related to mental health problems in younger and older caregivers. We studied 104 dementia caregivers; 46 were younger (<65 years) and 58 were older (≥65 years). A total of 104 community residents who were matched for age and gender were selected. We compared depression (Center for Epidemiologic Studies Depression Scale for younger participants; Geriatric Depression Scale for older participants), health-related quality of life (QOL) short-form health survey (SF-8), sleep problems, and suicidal ideation between the caregivers and community residents by age. Behavioural and psychological symptoms of dementia, activities of daily living (ADL), and instrumental ADL were assessed among patients with dementia using the Neuropsychiatric Inventory, Physical Self-Maintenance Scale, and Lawton Instrumental ADL Scale, respectively. According to SF-8 results, both younger and older caregivers had significantly worse mental QOL than community residents (younger caregivers: 46.3 vs community residents: 49.7, P = 0.017; older caregivers: 48.2 vs community residents: 51.1, P = 0.024) but were not more depressive. Sleep problems were significantly more frequent in younger caregivers (39.1%) than in community residents (17.0%) (P = 0.017). Multiple regression analysis revealed that caregivers' deteriorated mental QOL was associated with patients' behavioural and psychological symptoms of dementia in younger caregivers and with dementia patients' instrumental ADL and female gender in older caregivers. Dementia caregivers had a lower mental QOL than community residents. To maintain caregivers' mental QOL, it is necessary to provide younger

Older patients require more protein than younger patients to achieve anabolism, but age-associated renal dysfunction may limit the amount of protein that can be safely provided. This study examined whether older, critically ill trauma patients with obesity can safely achieve nitrogen equilibrium and have positive clinical outcomes similar to younger obese patients during hypocaloric, high-protein nutrition therapy. Adult patients with traumatic injury and obesity (body mass index [BMI] >30 kg/m(2)), admitted to the Presley Trauma Center from January 2009 to April 2011, were evaluated. Patients were targeted to receive hypocaloric, high-protein nutrition therapy (<25 kcal/kg ideal body weight [IBW]/d and >2 g/kg IBW/d of protein) for >10 days. Patients were stratified as older (≥60 years) or younger (18-59 years). Seventy-four patients (33 older, 41 younger) were studied. Older and younger patients were similar in BMI and injury severity. When given isonitrogenous regimens (2.3 ± 0.2 g/kg IBW/d), nitrogen balance was similar between older and younger patients (-3.2 ± 5.7 g/d vs -4.9 ± 9.0 g/d; P = .363). Older patients experienced a greater mean serum urea nitrogen concentration than younger patients (30 ± 14 mg/dL vs 20 ± 9 mg/dL; P = .001) during nutrition therapy. Clinical outcomes were not different between groups. Older critically ill trauma patients exhibited an equivalent net protein response as younger patients during hypocaloric, high-protein nutrition therapy. Older patients are at greater risk for developing azotemia. Close monitoring is warranted.

Dysphagia is associated with poor outcome in stroke patients. Studies investigating the association of dysphagia and early dysphagia screening (EDS) with outcomes in patients with acute ischemic stroke (AIS) are rare. The aims of our study are to investigate the association of dysphagia and EDS within 24 h with stroke-related pneumonia and outcomes. Over a 4.5-year period (starting November 2007), all consecutive AIS patients from 15 hospitals in Schleswig-Holstein, Germany, were prospectively evaluated. The primary outcomes were stroke-related pneumonia during hospitalization, mortality, and disability measured on the modified Rankin Scale ≥2-5, in which 2 indicates an independence/slight disability to 5 severe disability. Of 12,276 patients (mean age 73 ± 13; 49% women), 9,164 patients (74%) underwent dysphagia screening; of these patients, 55, 39, 4.7, and 1.5% of patients had been screened for dysphagia within 3, 3 to <24, 24 to ≤72, and >72 h following admission. Patients who underwent dysphagia screening were likely to be older, more affected on the National Institutes of Health Stroke Scale score, and to have higher rates of neurological symptoms and risk factors than patients who were not screened. A total of 3,083 patients (25.1%; 95% CI 24.4-25.8) had dysphagia. The frequency of dysphagia was higher in patients who had undergone dysphagia screening than in those who had not (30 vs. 11.1%; p < 0.001). During hospitalization (mean 9 days), 1,271 patients (10.2%; 95% CI 9.7-10.8) suffered from stroke-related pneumonia. Patients with dysphagia had a higher rate of pneumonia than those without dysphagia (29.7 vs. 3.7%; p < 0.001). Logistic regression revealed that dysphagia was associated with increased risk of stroke-related pneumonia (OR 3.4; 95% CI 2.8-4.2; p < 0.001), case fatality during hospitalization (OR 2.8; 95% CI 2.1-3.7; p < 0.001) and disability at discharge (OR 2.0; 95% CI 1.6-2.3; p < 0.001).

This study aimed to determine whether the clinicopathological features of lung cancer in patients younger than 40 years differ from that of older patients in an Asian country. We undertook a review of the clinicopathological data of all patients with confirmed primary lung cancer at the Department of Medicine, University of Malaya Medical Centre, Kuala Lumpur, Malaysia, from October 1991 to September 1999. Of the 580 patients with lung cancer, 36 (6.2%; 23 males, 13 females) were 21-39 years old at diagnosis. The percentage of people who had never smoked was higher among the younger patients (58.3% vs 19.1%, P < 0.001). Although adenocarcinoma was the most common cell type in both groups, its incidence was higher in the younger patients (24/36 (66.7%) vs 228/544 (41.9%), P = 0.007). The mean World Health Organization performance status at presentation was worse in the younger patients (2.4 vs 2, P = 0.007). In the case of non-small cell lung cancer, all the younger patients presented with either stage IIIb or metastatic disease compared to 77.2% of the older patients (P < 0.001). Younger lung cancer patients were more likely than older patients to have never smoked, to have adenocarcinoma, and to present with poorer performance status and with more advanced-stage non-small cell lung cancer.

Proximal large vessel occlusion (LVO) is present in up to 30% of minor strokes. The effectiveness of mechanical thrombectomy (MT) in the subgroup of minor stroke with LVO in the anterior circulation is still open to debate. Data about MT in this subgroup of patients are sparse, and their optimal management has not yet been defined. The purpose of this multicenter cohort study was to evaluate the effectiveness of MT in patients experiencing acute ischemic stroke (AIS) because of LVO in the anterior circulation, presenting with minor-to-mild stroke symptoms (National Institutes of Health Stroke Scale score of <8). Multicenter cohort study involving 4 comprehensive stroke centers having 2 therapeutic approaches (urgent thrombectomy associated with best medical treatment [BMT] versus BMT first and MT if worsening occurs) about management of patients with minor and mild acute ischemic stroke harboring LVO in the anterior circulation. An intention-to-treat analysis was conducted. The primary end point was the rate of excellent outcome defined as the achievement of a modified Rankin Scale score of 0 to 1 at 3 months. Three hundred one patients were included, 170 with urgent MT associated with BMT, and 131 with BMT alone as first-line treatment. Patients treated with MT were younger, more often received intravenous thrombolysis, and had shorter time to imaging. Twenty-four patients (18.0%) in the medical group had rescue MT because of neurological worsening. Overall, excellent outcome was achieved in 64.5% of patients, with no difference between the 2 groups. Stratified analysis according to key subgroups did not find heterogeneity in the treatment effect size. Minor-to-mild stroke patients with LVO achieved excellent and favorable functional outcomes at 3 months in similar proportions between urgent MT versus delayed MT associated with BMT. There is thus an urgent need for randomized trials to define the effectiveness of MT in this patient subgroup. © 2017 American Heart

Nonvalvular atrial fibrillation is common in elderly patients, who face an elevated risk of stroke but difficulty sustaining warfarin treatment. The oral factor Xa inhibitor rivaroxaban was noninferior to warfarin in the Rivaroxaban Once Daily, Oral, Direct Factor Xa Inhibition Compared With Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial Fibrillation (ROCKET AF). This prespecified secondary analysis compares outcomes in older and younger patients. There were 6229 patients (44%) aged ≥75 years with atrial fibrillation and ≥2 stroke risk factors randomized to warfarin (target international normalized ratio=2.0-3.0) or rivaroxaban (20 mg daily; 15 mg if creatinine clearance <50 mL/min), double blind. The primary end point was stroke and systemic embolism by intention to treat. Over 10 866 patient-years, older participants had more primary events (2.57% versus 2.05%/100 patient-years; P=0.0068) and major bleeding (4.63% versus 2.74%/100 patient-years; P<0.0001). Stroke/systemic embolism rates were consistent among older (2.29% rivaroxaban versus 2.85% warfarin per 100 patient-years; hazard ratio=0.80; 95% confidence interval, 0.63-1.02) and younger patients (2.00% versus 2.10%/100 patient-years; hazard ratio=0.95; 95% confidence interval, 0.76-1.19; interaction P=0.313), as were major bleeding rates (≥75 years: 4.86% rivaroxaban versus 4.40% warfarin per 100 patient-years; hazard ratio=1.11; 95% confidence interval, 0.92-1.34; <75 years: 2.69% versus 2.79%/100 patient-years; hazard ratio=0.96; 95% confidence interval, 0.78-1.19; interaction P=0.336). Hemorrhagic stroke rates were similar in both age groups; there was no interaction between age and rivaroxaban response. Elderly patients had higher stroke and major bleeding rates than younger patients, but the efficacy and safety of rivaroxaban relative to warfarin did not differ with age, supporting rivaroxaban as an alternative for the elderly. © 2014 American Heart Association, Inc.

Obstructive sleep apnea exaggerates cognitive dysfunction in stroke patients.

Obstructive sleep apnea (OSA) is very common in stroke survivors. It potentially worsens the cognitive dysfunction and inhibits their functional recovery. However, whether OSA independently damages the cognitive function in stroke patients is unclear. A simple method for evaluating OSA-induced cognitive impairment is also missing. Forty-four stroke patients six weeks after onset and 24 non-stroke patients with snoring were recruited for the polysomnographic study of OSA and sleep architecture. Their cognitive status was evaluated with a validated Chinese version of Cambridge Prospective Memory Test. The relationship between memory deficits and respiratory, sleeping, and dementia-related clinical variables were analyzed with correlation and multiple linear regression tests. OSA significantly and independently damaged time- and event-based prospective memory in stroke patients, although it had less power than the stroke itself. The impairment of prospective memory was correlated with increased apnea-hypopnea index, decreased minimal and mean levels of peripheral oxygen saturation, and disrupted sleeping continuity (reduced sleep efficiency and increased microarousal index). The further regression analysis identified minimal levels of peripheral oxygen saturation and sleep efficiency to be the two most important predictors for the decreased time-based prospective memory in stroke patients. OSA independently contributes to the cognitive dysfunction in stroke patients, potentially through OSA-caused hypoxemia and sleeping discontinuity. The prospective memory test is a simple but sensitive method to detect OSA-induced cognitive impairment in stroke patients. Proper therapies of OSA might improve the cognitive function and increase the life quality of stroke patients. Copyright © 2017 Elsevier B.V. All rights reserved.

Nutrition affects rehabilitation through its influence on physical and mental functioning, although little attention has been paid to effects on rehabilitation outcomes. The present study aimed to describe nutritional status and food consumption in stroke patients within 2 weeks of hospital admission and before discharge, as well as to investigate the effects of nutritional and dietary factors on rehabilitation outcomes. One hundred patients from a consecutive cohort admitted to a metropolitan hospital with acute stroke were recruited and assessed by a single researcher, with 38 reassessed at discharge. Nutritional status was assessed using Mini-Nutritional Assessment and anthropometric indices and dietary intake was assessed by 1-day weighed dietary records. Rehabilitation outcomes were changes in Barthel index scores and the rehabilitation efficiency index. Few (n = 9; 10%) consumed ≥100% of the estimated average requirement (EAR) for energy within 2 weeks of admission and 13 (33%) had energy intakes <50% of EAR before discharge. A small but increasing proportion (7% at admission, 13% at discharge) were identified as being malnourished across the inpatient stay. Younger age, lower Barthel index and a higher energy intake in the early stages of admission predicted the extent and rate of restoration of functional abilities by discharge (F = 7.503, P = 0.001; F = 14.558, P < 0.001). Given a general finding of nutritional deterioration identified for these patients, as well as the identification of energy intake as a modifiable influence on the extent and rate of recovery, there is clearly scope for the multidisciplinary development of nutritional support for stroke patients to improve rehabilitation outcomes. © 2011 The Authors.

>50% of stroke patients rely on analgesic medication to control pain. Aspirin is the mainstay of medical treatment of stroke patients; however analgesic medication with dipyrone impairs aspirin antiplatelet effects ex-vivo. The clinical impact of this impairment is unknown. Therefore, we aimed to determine aspirin antiplatelet effects and neurological outcome in stroke patients with aspirin and dipyrone comedication. We conducted a prospective cohort study in 41 patients with stroke. Primary outcome was pharmacodynamic response to aspirin in dipyrone treated stroke patients. Secondary outcome was neurological recovery after stroke. Pharmacodynamic response to aspirin was measured using arachidonic acid induced aggregation in light-transmission aggregometry. Neurological outcome was determined three months after stroke onset by telephone interview. Patient's characteristics were similar in the aspirin-alone group and the aspirin+dipyrone group. Impaired pharmacodynamic response to aspirin occurred in 62% (14/21) of patients with aspirin and dipyrone co-medication. Only 10% (2/20) of aspirin treated patients without analgesic comedication displayed residual platelet reactivity (P=0.001; odds ratio [OR], 18 [95% CI, 3.2-100]). Excellent neurological recovery (measured by three months follow-up modified Rankin Scale<2) was observed in 80% (16/20) of patients in the aspirin-alone group and 48% (10/21) of patients in the aspirin+dipyrone group (P=0.037; OR, 4.4 [95% CI, 1.1-17.7]). Dipyrone comedication in patients with stroke impairs pharmacodynamic response to aspirin. This is associated with worse clinical outcome. Therefore dipyrone should be used with caution in aspirin treated stroke patients. https://clinicaltrials.gov/show/NCT02148939; Identifier: NCT02148939. Copyright © 2016 Elsevier Inc.

Background and Purpose Current literature provides mixed evidence on disparities by race/ethnicity and socioeconomic status (SES) in discharge outcomes following hospitalization for acute ischemic stroke. Using comprehensive data from eight states, we sought to compare inpatient mortality and length of stay (LOS) by race/ethnicity and SES. Methods We examined all 2007 hospitalizations for acute ischemic stroke in all non-Federal acute care hospitals in AZ, CA, FL, MA, NJ, NY, PA and TX. Population was stratified by race/ethnicity (non-Hispanic Whites, non-Hispanic Blacks and Hispanics) and SES, measured by median income of patient zip code. For each stratum we estimated risk-adjusted rates of inpatient mortality and longer LOS (> median LOS). We also compared the hospitals where these subpopulations received care. Results Hispanic and Black patients accounted for 14 and 12 percent of all ischemic stroke admissions (N=147,780) respectively and had lower crude inpatient mortality rates (Hispanic=4.5%, Blacks=4.4%; all p-values < 0.001) compared to White patients (5.8%). Hispanic and Black patients were younger and fewer had any form of atrial fibrillation. Adjusted for patient risk, inpatient mortality was similar by race/ethnicity, but was significantly higher for low area-income patients than that for high area-income patients (Odds Ratio=1.08, 95% confidence interval=[1.02, 1.15]). Risk-adjusted rates of longer LOS were higher among minority and low area-income populations. Conclusions Risk adjusted inpatient mortality was similar among patients by race/ethnicity but higher among patients from lower income areas. However, this pattern was not evident in sensitivity analyses including the use of mechanical ventilation as a partial surrogate for stroke severity. PMID:23306327

Comparisons of rhythm and rate control strategies for stroke prevention in patients with atrial fibrillation (AF) are still inconclusive. We compared differences in clinical outcomes between the rhythm and rate control strategies. The COmparison study of Drugs for symptom control and complication prEvention of Atrial Fibrillation (CODE-AF) registry prospectively enrolled 6000 patients who were treated for AF using real-world guideline adherence at multiple referral centers. In total, 2508 (41.8%) patients were clinically followed up for over six months. Of these, 1134 (45.2 %) patients treated by rhythm control and 1374 (54.8 %) patients treated by rate control were analyzed for clinical outcomes, including stroke and cardiovascular outcomes. Among all patients (age, 68±10 years; male, 62.4%), those treated with the rhythm control strategy were significantly younger, had more symptomatic paroxysmal AF, and a shorter AF duration, and were less likely to have diabetes, renal dysfunction, and heart failure, compared to those treated with the rate control strategy (CHA₂DS₂-VASc score 2.4±1.5 vs. 3.1±1.7, p<0.001). Even though oral anticoagulation was similarly prescribed in both groups, occurrence of stroke was less likely to occur in the rhythm control strategy group (0.0% vs. 0.7%, p=0.015). Multivariate Cox hazard regression showed that only age, especially more than 75 years old, were significantly correlated with the occurrence of stroke, regardless of the strategy used for treatment. In this prospective AF cohort, compared with the rate control strategy, the rhythm control strategy was associated with fewer cardiovascular events and strokes in a short-term period. © Copyright: Yonsei University College of Medicine 2018

Infliximab (IFX) is efficacious for induction and maintenance of remission in pediatric patients with moderate-to-severe inflammatory bowel disease (IBD). It has, however, not been studied in patients 7 years old and younger. Our aim was to characterize efficacy and safety of IFX therapy in this cohort. This was a retrospective study of patients with IBD ages 7 years and younger, treated with IFX between 1999 and 2011. Medical records were reviewed for age of diagnosis, disease phenotype, therapy, surgery, IFX infusion dates, dose, and intervals. Outcome measures included physician global assessment, corticosteroid requirement, and adverse events. Thirty-three children (ages 2.4-7 years) were included. Twenty patients had Crohn disease, 4 had ulcerative colitis, and 9 had indeterminate colitis. Maintenance of IFX therapy at 1, 2, and 3 years was 36%, 18%, and 12%, respectively. Patients of age 5 years and younger had the lowest rates of maintenance of therapy at 25% at year 1, and 10% at years 2 and 3 combined. Nine percent of all of the patients demonstrated response measured by the physician global assessment and were steroid free at 1 year. There were 8 infusion reactions. There were no malignancies, serious infections, or deaths. IFX demonstrated a modest response rate and a low steroid-sparing effect in patients with IBD 7 years old and younger. Although this is a limited study, there appears to be a trend for decreased sustained efficacy with IFX in this age group, particularly in children 5 years old and younger, when compared with the previously published literature in older children.

The clinical implications of vertebrobasilar ectasia (VBE) in patients with cerebral small-artery disease are not well defined. We investigated whether VBE is associated with recurrent stroke, major hemorrhage, and death in a large cohort of patients with recent lacunar stroke. Maximum diameters of the vertebral and basilar arteries were measured by magnetic resonance angiography and computed tomographic angiography in 2621 participants in the Secondary Prevention of Small Subcortical Strokes trial. VBE was defined a priori as basilar artery greater than 4.5 mm and/or vertebral artery greater than 4.0 mm. Patient characteristics and risks of stroke recurrence and mortality during follow-up (median, 3.5 years) were compared between patients with and without VBE. VBE affecting 1 or more arteries was present in 200 (7.6%) patients. Patient features independently associated with VBE were increasing age, male sex, white race ethnicity, hypertension, and higher baseline diastolic blood pressure. Baseline systolic blood pressure was inversely associated with VBE. After adjustment for other risk factors, VBE was not predictive of recurrent stroke (hazard ratio [HR], 1.3; 95% confidence interval [CI], .85-1.9) or major hemorrhage (HR, 1.5; CI, .94-2.6), but was of death (HR, 1.7; CI, 1.1-2.7). In this large well-characterized cohort of patients with recent lacunar stroke, VBE was predictive of death but not of recurrent stroke or major hemorrhage. In these exploratory analyses, the frequency of VBE was directly related to diastolic blood pressure but inversely related to systolic blood pressure. Copyright © 2015 National Stroke Association.

Limited information is available regarding differences in neuroimaging use for acute stroke work-up. Our objective was to assess whether race, sex, or age differences exist in neuroimaging use and whether these differences depend on the care center type in a population-based study. Patients with stroke (ischemic and hemorrhagic) and transient ischemic attack were identified in a metropolitan, biracial population using the Greater Cincinnati/Northern Kentucky Stroke Study in 2005 and 2010. Multivariable regression was used to determine the odds of advanced imaging use (CT angiography/MR imaging/MR angiography) for race, sex, and age. In 2005 and 2010, there were 3471 and 3431 stroke/TIA events, respectively. If one adjusted for covariates, the odds of advanced imaging were higher for younger (55 years or younger) compared with older patients, blacks compared with whites, and patients presenting to an academic center and those seen by a stroke team or neurologist. The observed association between race and advanced imaging depended on age; in the older age group, blacks had higher odds of advanced imaging compared with whites (odds ratio, 1.34; 95% CI, 1.12-1.61; P < .01), and in the younger group, the association between race and advanced imaging was not statistically significant. Age by race interaction persisted in the academic center subgroup ( P < .01), but not in the nonacademic center subgroup ( P = .58). No significant association was found between sex and advanced imaging. Within a large, biracial stroke/TIA population, there is variation in the use of advanced neuroimaging by age and race, depending on the care center type. © 2017 by American Journal of Neuroradiology.

Physical Activity Patterns of Acute Stroke Patients Managed in a Rehabilitation Focused Stroke Unit

PubMed Central

2013-01-01

Background. Comprehensive stroke unit care, incorporating acute care and rehabilitation, may promote early physical activity after stroke. However, previous information regarding physical activity specific to the acute phase of stroke and the comprehensive stroke unit setting is limited to one stroke unit. This study describes the physical activity undertaken by patients within 14 days after stroke admitted to a comprehensive stroke unit. Methods. This study was a prospective observational study. Behavioural mapping was used to determine the proportion of the day spent in different activities. Therapist reports were used to determine the amount of formal therapy received on the day of observation. The timing of commencement of activity out of bed was obtained from the medical records. Results. On average, patients spent 45% (SD 25) of the day in some form of physical activity and received 58 (SD 34) minutes per day of physiotherapy and occupational therapy combined. Mean time to first mobilisation out of bed was 46 (SD 32) hours post-stroke. Conclusions. This study suggests that commencement of physical activity occurs earlier and physical activity is at a higher level early after stroke in this comprehensive stroke unit, when compared to studies of other acute stroke models of care.

2015-09-01

This study aimed to assess the association between diabetes and risk of stroke recurrence (especially ischemic stroke recurrence) and to evaluate whether diabetes was an independent predictor for stroke recurrence in stroke patients with diabetes. The relevant studies were identified through searching databases of PubMed, EMBASE, and Cochrane library. Adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) were pooled to evaluate the association between diabetes and risk of stroke recurrence. Funnel plot and Egger's regression tests were used to assess publication bias. All statistical analyses were conducted in Stata 12.0. Eighteen studies containing totally 43,899 participants were included in the meta-analysis. The results showed that stroke recurrence risk of all stroke patients with diabetes was significantly higher than those without diabetes (HR, 1.45; 95% CI, 1.32-1.59), similar results were achieved in ischemic stroke patients (HR, 1.44; 95% CI, 1.28-1.61), and there were no regional differences (Europe: HR, 1.28; 95% CI, 1.13-1.44; USA: HR, 1.89; 95% CI, 1.53-2.33; Asia: HR, 1.57, 95% CI, 1.28-1.92, respectively) and age differences (mean age <70 years: HR, 1.58; 95% CI, 1.34-1.86; mean age ≥70 years: HR, 1.27; 95% CI, 1.11-1.45, respectively). The heterogeneity of all included studies was not statistically significant, and no publication bias was observed. This meta-analysis shows that diabetes is an independent risk factor for stroke recurrence in stroke patients. Copyright © 2015. Published by Elsevier Inc.

There has been an increasing interest in the arts in health care, with a suggestion that the arts and aesthetics can augment patient outcomes in stroke and other illnesses. Designing such programmes requires better knowledge of the artistic, aesthetic, and cultural pursuits of people affected by stroke. The aim of this study was to obtain the insights of this group about the profile of art and aesthetic activities in their lives and the influence of stroke on these aspects. Patients attending a stroke service were administered questions adapted from the Irish Arts Council's 2006 questionnaire on participation in aesthetics and cultural pursuits. Information was also collected on stroke type and present functional and cognitive status. Thirty-eight patients were interviewed. Of these, 20 were inpatients in hospital at the time of the interview and 18 were interviewed in an outpatient setting. Popular activities included mainstream cinema, listening to music, dancing, attending plays or musicals, and being outdoors. Many patients ceased these activities after their stroke, mostly because of health issues and inaccessibility. Most of the patients valued the importance of the arts in the health-care setting. This study gives a perspective for the first time on the aesthetic and cultural pursuits of stroke patients before their stroke. It portrays a wide variety of cultural and leisure activities and the cessation of these poststroke. It revealed the restrictions patients felt on gaining access to leisure pursuits both while in hospital and following discharge. Copyright © 2013 National Stroke Association.

Rousseaux, Marc; Daveluy, Walter; Kozlowski, Odile

2010-07-01

In stroke patients, it has been suggested that communication disorders could result from lexical and syntactic disorders in left hemisphere lesions and from pragmatics problems in right lesions. However, we have little information on patient behaviour in dyadic communication, especially in conversation. Here, we analyzed the various processes participating in communication difficulties at the rehabilitation phase (1-6 months) post-stroke, in order to define the main mechanisms of verbal and non-verbal communication (VC, NVC) disorders and their relationship with aphasic disorders. Sixty-three patients were recruited, who belonged to six groups, with left or right cortico-sub-cortical (L-CSC, R-CSC) or sub-cortical (L-SC, R-SC), frontal (Fro) or posterior fossa (PF) lesions. They were compared with an equivalent control group (gender, age, education level). We used the Lille Communication Test, which comprises three parts: participation to communication (greeting, attention, engagement), verbal communication (verbal comprehension, speech outflow, intelligibility, word production, syntax, verbal pragmatics and verbal feedback) and non-verbal communication (understanding gestures, affective expressivity, producing gestures, pragmatics and feedback). We also used the Functional Communication Profile and the Boston Diagnostic Aphasia Examination (BDAE). Decrease in participation was found in L-CSC, R-CSC and Fro patients. Verbal communication was essentially disrupted in L-SCS and L-SC groups, including by verbal pragmatic disorders, and to a lesser degree in frontal patients. Nonverbal communication was mainly affected in R-CSC patients, especially by pragmatic difficulties. L-CSC patients showed an increase in gesture production, compensating for aphasia. In conclusion, communication disorders were relatively complex and could not be summarised by syntactical and lexical difficulties in left stroke and pragmatic problems in right stroke. The former also showed severe

To investigate the risk of stroke development following a diagnosis of Bell's palsy in a nationwide follow-up study. Information on Bell's palsy and other factors relevant for stroke was obtained for 433218 eligible subjects without previous stroke who had ambulatory visit in 2004. Of those, 897 patients with Bell's palsy were identified. Over a median 2.9 years of follow-up, 4581 incident strokes were identified. We estimated hazard ratios (HR) and 95% confidence intervals [CI] with Cox proportional hazard models adjusting for age, sex, co-morbidities, and important risk factors. Standardized incidence ratio of stroke amongst patients with Bell's palsy was analyzed. Compared with non-Bell's palsy patients, patients with Bell's palsy had a 2.02-times (95% CI, 1.42-2.86) higher risk of stroke. The adjusted HR of developing stroke for patients with Bell's palsy treated with and without systemic steroid were 1.67 (95% CI, 0.69-4) and 2.10 (95%, 1.40-3.07), respectively. Patients with Bell's palsy carry a higher risk of stroke than the general population. Our data suggest that these patients might benefit from a more intensive stroke prevention therapy and regular follow-up after initial diagnosis. © 2012 The Author(s) European Journal of Neurology © 2012 EFNS.

Is acupuncture an acceptable option in stroke rehabilitation? A survey of stroke patients.

PubMed

Yam, Winnie; Wilkinson, Jenny M

2010-01-01

Stroke is a leading cause of morbidity and mortality and stroke survivors make up the largest group of patients in rehabilitation. These individuals also have one of the longest lengths of stay in rehabilitation. It has been suggested that acupuncture may be beneficial in post-stroke rehabilitation and in this study we examine how stroke patients value acupuncture and their perceptions of acupuncture as a rehabilitation treatment option. A questionnaire was distributed to individuals undergoing post-stroke rehabilitation at three rehabilitation centers attached to hospitals in Toronto, Canada. Two hundred and seventy-three individuals completed the questionnaire with the respondent group comprising mainly males (62%) over 65 years of age (68%). Overall 29% had used acupuncture with 16% receiving acupuncture treatment for stroke related conditions. Almost all respondents (98%) wanted to know more about acupuncture in stroke rehabilitation and 87% would consider acupuncture as a treatment option. Few (8%) reported that they had advanced level knowledge about acupuncture, with most reporting a basic (48%) or intermediate (33%) level which recognized that acupuncture used fine needles to produce a therapeutic response. Those with prior acupuncture experience expected to pay more for treatment. The main factors influencing decisions to use acupuncture were practitioner competency (84%), cost (65%) and sterilization concerns (40%). This study demonstrates that there is willingness by patients attending conventional hospital-based rehabilitation centers to consider acupuncture in stroke rehabilitation and that lack of knowledge about this treatment is not a barrier to use.

Edaravone offers neuroprotection for acute diabetic stroke patients.

PubMed

Zheng, J; Chen, X

2016-11-01

Edaravone, a novel free-radical scavenger, has been shown to alleviate cerebral ischemic injury and protect against vascular endothelial dysfunction. However, the effects of edaravone in acute diabetic stroke patients remain undetermined. A randomized, double-blind, placebo-controlled study was performed to prospectively evaluate the effects of edaravone on acute diabetic stroke patients admitted to our hospital within 24 h of stroke onset. The edaravone group received edaravone (30 mg twice per day) diluted with 100 ml of saline combined with antiplatelet drug aspirin and atorvastatin for 14 days. The non-edaravone group was treated only with 100 ml of saline twice per day combined with aspirin and atorvastatin. Upon admission, and on days 7, 14 post-stroke onset, neurological deficits and activities of daily living were assessed using the National Institutes of Health Stroke Scale (NIHSS) and the Barthel Index (BI), respectively. The occurrence of hemorrhage transformation, pulmonary infection, progressive stroke and epilepsy was also evaluated on day 14 post-treatment. A total of 65 consecutive acute diabetic stroke patients were enrolled, of whom 35 were allocated to the edaravone group and 30 to the non-edaravone group. There was no significant group difference in baseline clinical characteristics, but mean NIHSS scores were lower (60 %), and BI scores were 1.7-fold higher, in edaravone-treated patients vs. controls on day 14. Furthermore, the incidence of hemorrhage transformation, pulmonary infection, progressive stroke and epilepsy was markedly reduced in the edaravone vs. non-edaravone group. Edaravone represents a promising neuroprotectant against cerebral ischemic injury in diabetic patients.

Age-Group and Gender Differences in Stroke Knowledge in an Israeli Jewish Adult Population.

Melnikov, Semyon; Itzhaki, Michal; Koton, Silvia

Stroke is a leading cause of long-term disability and the fifth leading cause of death in Israel. Knowledge of stroke warning signs has been linked to early seeking of medical help. Little is known about knowledge of stroke warning signs in Israeli Jewish adults. Stroke knowledge was examined among Jewish Israeli adults. Using a structured questionnaire, registered nurses interviewed a convenience sample of the respondents, 18 years or older, with no stroke history. Stroke knowledge and demographics were examined by 3 age groups (<45, 45-64, and >64 years) in men and women. In total, 1137 Jewish Israelis were interviewed, 457 (40.2%) men and 680 women (59.8%); 493 (43.4%) were younger than 45 years, 541 (47.6%) were aged 45 to 64 years, and 102 (9%) were older than 64 years; 1 (0.1%) did not report age. On average, each interview lasted for 25 to 30 minutes. Participants younger than 45 years showed the lowest knowledge of stroke cause. Women younger than 45 years were less likely to identify at least 2 stroke warning signs. Participants younger than 45 years were less likely to identify at least 2 risk factors, compared with participants aged 45 to 64 years and older than 64 years. Women younger than 45 years were less likely to identify at least 2 stroke prevention strategies. Participants younger than 45 years showed the lowest levels of stroke knowledge. The highest stroke knowledge was found in the 45 to 64 years age group. Stroke knowledge among different age groups was similar in both genders. Educational campaigns aimed at increasing knowledge of stroke among the general population and targeting the younger population are recommended.

The Indo-US Collaborative Stroke Project was designed to characterize ischemic stroke across 5 high-volume academic tertiary hospitals in India. From January 2012 to August 2014, research coordinators and physician coinvestigators prospectively collected data on 2066 patients with ischemic stroke admitted <2 weeks after onset. Investigator training and supervision and data monitoring were conducted by the US site (Massachusetts General Hospital, Boston). The mean age was 58.3±14.7 years, 67.2% men. The median admission National Institutes of Health Stroke Scale score was 10 (interquartile range, 5-15) and 24.5% had National Institutes of Health Stroke Scale ≥16. Hypertension (60.8%), diabetes mellitus (35.7%), and tobacco use (32.2%, including bidi/smokeless tobacco) were common risk factors. Only 4% had atrial fibrillation. All patients underwent computed tomography or magnetic resonance imaging; 81% had cerebrovascular imaging. Stroke etiologic subtypes were large artery (29.9%), cardiac (24.9%), small artery (14.2%), other definite (3.4%), and undetermined (27.6%, including 6.7% with incomplete evaluation). Intravenous or intra-arterial thrombolysis was administered in 13%. In-hospital mortality was 7.9%, and 48% achieved modified Rankin Scale score 0 to 2 at 90 days. On multivariate analysis, diabetes mellitus predicted poor 3-month outcome and younger age, lower admission National Institutes of Health Stroke Scale and small-artery etiology predicted excellent 3-month outcome. These comprehensive and novel clinical imaging data will prove useful in refining stroke guidelines and advancing stroke care in India. © 2017 American Heart Association, Inc.

Stroke patients are at particular risk for developing pulmonary embolism (PE), which is a cardiovascular emergency associated with a high mortality rate. Little information is available on symptomatic PE in Asian stroke patients. To determine the frequency of symptomatic PE in ischemic and hemorrhagic stroke patients; to identify common characteristics and risk factors of symptomatic PE in Taiwanese stroke patients; and to compare the difference between fatal PE and nonfatal PE among these stroke patients. This is a retrospective cohort study of stroke patients admitted between January 2002 and December 2009 to a tertiary referral center in Northern Taiwan. We used the International Classification of Diseases, Ninth Revision, Clinical Modification codes to identify eligible patients. We determined annual frequency and risk factors of symptomatic PE. We also compared the difference between ischemic stroke patients with fatal and nonfatal PE. Among the admitted stroke patients, 21,129 (78.87%) had ischemic strokes and 5,662 (21.13 %) had hemorrhagic strokes. There were 14 (0.066%) ischemic and 1 hemorrhagic stroke (0.018%) patients included in this study. Of the recruited stroke patients, 64.29% had past heart disease history, especially atrial fibrillation (42.86%). Patients with fatal PE showed a significantly lower poststroke Glasgow Coma Scale (GCS) motor component than patients with nonfatal PE. Symptomatic PE is not common in stroke patients in Taiwan. Clinicians need to keep this fatal disease in mind, especially for persons with heart disease like atrial fibrillation. Stroke patients with impaired poststroke GCS motor components seemed to have a greater mortality risk if they have symptomatic PE.

To describe the time use of patients with stroke in five Skilled Nursing Facilities (SNFs) in the Netherlands, focusing on the time spent on therapeutic activities, nontherapeutic activities, interaction with others, and the location where the activities took place. Evidence suggest that task-oriented interventions are the most effective for patients with stroke and that some of these interventions are relevant and feasible for use by nurses. The question arises to what extent elderly patients who had a stroke and rehabilitate in a SNF receive therapeutic training and engage in therapeutic activities. Descriptive, observational design. Therapeutic and nontherapeutic activities of patients were observed at 10-minute intervals during one weekday (8 a.m.-4:30 p.m.) using behavioral mapping. Forty-two patients with stroke with a mean age of 76 years participated in the study. The patients spent 56% of the day on therapeutic activities, whereas 44% of the day was spent on nontherapeutic activities. Most therapeutic time was spent on nursing care (9%) and physical therapy (4%). Patients stayed an average 41% of the day in their own room and were alone 49% of the day. Therapeutic time use was significantly related to improved functional status, patients with higher functional status spent more time on therapeutic activities. Patients spent more than half of the day on therapeutic activities. Nurses are faced with the challenge of activating patients with stroke and to assist them to engage in purposeful task-oriented exercises including daily activities. Thereby better rehabilitation results and recovery of patients may be reached. © 2013 Association of Rehabilitation Nurses.

To investigate the diagnostic yield of prehospital ECG monitoring provided by emergency medical services in the case of suspected stroke. Consecutive patients with acute stroke admitted to our tertiary stroke center via emergency medical services and with available prehospital ECG were prospectively included during a 12-month study period. We assessed prehospital ECG recordings and compared the results to regular 12-lead ECG on admission and after continuous ECG monitoring at the stroke unit. Overall, 259 patients with prehospital ECG recording were included in the study (90.3% ischemic stroke, 9.7% intracerebral hemorrhage). Atrial fibrillation (AF) was detected in 25.1% of patients, second-degree or greater atrioventricular block in 5.4%, significant ST-segment elevation in 5.0%, and ventricular ectopy in 9.7%. In 18 patients, a diagnosis of new-onset AF with direct clinical consequences for the evaluation and secondary prevention of stroke was established by the prehospital recordings. In 2 patients, the AF episodes were limited to the prehospital period and were not detected by ECG on admission or during subsequent monitoring at the stroke unit. Of 126 patients (48.6%) with relevant abnormalities in the prehospital ECG, 16.7% received medical antiarrhythmic therapy during transport to the hospital, and 6.4% were transferred to a cardiology unit within the first 24 hours in the hospital. In a selected cohort of patients with stroke, the in-field recordings of the ECG detected a relevant rate of cardiac arrhythmia. The results can add to the in-hospital evaluation and should be considered in prehospital care of acute stroke. © 2017 American Academy of Neurology.

Urinary incontinence (UI) is a predictor of greater mortality and poor functional recovery; however published studies failed to evaluate lower urinary tract (LUT) function immediately after stroke. The aim of our study was to evaluate the course of LUT function in the first week after stroke, and its impact on prognosis. We included 100 consecutively admitted patients suffering first-ever stroke and evaluated them within 72 hours after stroke, after 7 days, 6 months, and 12 months. For LUT function assessment we used ultrasound measurement. The patients were divided into three groups: (i) patients who remained continent after stroke, (ii) patients who had LUT dysfunction in the acute phase but regained continence in the first week, and (iii) patients who did not regain normal LUT control in the first week. We assessed the influence of variables on death using the multiple logistic regression model. Immediately after stroke 58 patients had LUT dysfunction. The odds of dying in group with LUT dysfunction were significantly larger than odds in group without LUT dysfunction. Odds for death for patients who regained LUT function in 1 week after stroke were comparable to patients without LUT dysfunction. We confirmed that post-stroke UI is a predictor of greater mortality at 1 week, 6 months and 12 months after stroke. However, patients who regain normal bladder control in the first week have a comparable prognosis as the patients who do not have micturition disturbances following stroke.

Street, Brian D; Gage, William

2017-05-01

National joint replacement registries have reported a substantial growth in younger knee osteoarthritic patients (<55years old) undergoing total knee replacement, however this younger population is generally understudied. Importantly, studies examining experimentally controlled perturbation have shown age-related differences between younger and older healthy adults, whether similar age-related differences exist among total knee replacement patients is unknown. A total of 59 participants, including 29 unilateral total knee replacement patients (six-months post-surgery) made up the four experimental groups: 1) younger patient (54.3 (SD 7.9) years), 2) younger control (55.2 (SD 4.0) years), 3) older patient (76.9 (SD 4.7) years), and 4) older control (77.7 (SD 4.1) years). Using a tether-release method to perturb balance and simulate a forward fall, center of mass and stepping characteristics were analyzed. Younger patients recovered following the perturbation with a significantly smaller center of mass displacement compared to the older patients (14.85 (SD 0.01) v. 18.13 (SD 0.02) %ht, p=0.02); utilizing a longer (0.43 (SD 0.02) v. 0.39 (SD 0.03) m, p<0.001) and higher velocity (2.01 (SD 0.2) v. 1.59 (SD 0.2) m/s, p=0.001) recovery step. Importantly, younger patients did not differ significantly from the younger controls in center of mass displacement or recovery step characteristics (p>0.05). The younger patients demonstrated superior center of mass control in response to a forward perturbation, suggesting that younger patients would be at a reduced risk of falling when recovering from a forward-directed postural perturbation compared to older patients.

Post-stroke prognoses are usually inductive, generalizing trends learned from one group of patients, whose outcomes are known, to make predictions for new patients. Research into the recovery of language function is almost exclusively focused on monolingual stroke patients, but bilingualism is the norm in many parts of the world. If bilingual language recruits qualitatively different networks in the brain, prognostic models developed for monolinguals might not generalize well to bilingual stroke patients. Here, we sought to establish how applicable post-stroke prognostic models, trained with monolingual patient data, are to bilingual stroke patients who had been ordinarily resident in the UK for many years. We used an algorithm to extract binary lesion images for each stroke patient, and assessed their language with a standard tool. We used feature selection and cross-validation to find ‘good’ prognostic models for each of 22 different language skills, using monolingual data only (174 patients; 112 males and 62 females; age at stroke: mean = 53.0 years, standard deviation = 12.2 years, range = 17.2–80.1 years; time post-stroke: mean = 55.6 months, standard deviation = 62.6 months, range = 3.1–431.9 months), then made predictions for both monolinguals and bilinguals (33 patients; 18 males and 15 females; age at stroke: mean = 49.0 years, standard deviation = 13.2 years, range = 23.1–77.0 years; time post-stroke: mean = 49.2 months, standard deviation = 55.8 months, range = 3.9–219.9 months) separately, after training with monolingual data only. We measured group differences by comparing prediction error distributions, and used a Bayesian test to search for group differences in terms of lesion-deficit associations in the brain. Our models distinguish better outcomes from worse outcomes equally well within each group, but tended to be over-optimistic when predicting bilingual language outcomes: our bilingual patients tended to have poorer language skills

Malnutrition in Patients with Acute Stroke

PubMed Central

Bouziana, Stella D.; Tziomalos, Konstantinos

2011-01-01

Stroke is a devastating event that carries a potential for long-term disability. Malnutrition is frequently observed in patients with stroke, and dysphagia contributes to malnutrition risk. During both the acute phase of stroke and rehabilitation, specific nutritional interventions in the context of a multidisciplinary team effort can enhance the recovery of neurocognitive function. Early identification and management of malnutrition with dietary modifications or specific therapeutic strategies to ensure adequate nutritional intake should receive more attention, since poor nutritional status appears to exacerbate brain damage and to contribute to adverse outcome. The main purpose of nutritional intervention should be the prevention or treatment of complications resulting from energy-protein deficit. This paper reviews the evaluation and management of malnutrition and the use of specialized nutrition support in patients with stroke. Emphasis is given to enteral tube and oral feeding and to strategies to wean from tube feeding. PMID:22254136

Angiotensin-1-converting enzyme (ACE) is a crucial player in vascular homeostasis and in the pathogenesis of atherosclerosis and hypertension. The present study was conducted to determine whether there is an association between the ACE insertion/deletion (I/D) polymorphism and ischemic stroke in Egyptian population. Also, we analyzed the ACE gene I/D polymorphism as a risk factor for small-vessel (SV) versus large-vessel (LV) disease. Sixty patients with ischemic stroke were included: 30 with SV disease and 30 with LV disease. In addition, a control group of 30 apparent healthy subjects were studied. Clinical assessment, computed tomography, magnetic resonance imaging brain, and genetic study using the polymerase chain reaction of ACE gene were done for all subjects. We found that the distribution of ACE gene polymorphism frequency was significantly different between the 3 groups. The DD genotype was far more common in stroke patients compared to controls. It was also significantly more common in each of the patient groups compared to controls but rather similar in the 2 patient groups with SV and LV diseases. We found that the ACE gene deletion/deletion genotype is common in Egyptian patients with non-cardioembolic ischemic stroke but does not appear to be specific neither to SV nor to LV disease.

[Vein thromboembolism prevention in stroke patients].

PubMed

Savić, Dejan; Savić, Ljiljana

2010-01-01

Having in mind the rate of occurrence and clinical importance, venous thromboembolism implies venous thrombosis and pulmonary embolism as a result of embolisation of the thrombotic particles from deep veins or pelvic veins. Venous thrombosis of the deep veins may result in chronic vein insufficiency, but the primary medical problem is the possibility of development of pulmonary embolism which may cause permanent respiratory function damage or even fatal outcome. The high incidence of deep vein thrombosis (30% clinically and up to 50% subclinically) in acute stroke hemiparetic and bed ridden patients within two weeks from the onset and 1-2% pulmonary embolism with the fatal outcome in the first month clinically and 17% of all fatal outcomes in postmortem investigations present a necessity for the early venous thromboembolism prevention. On the other hand, the most powerful prevention strategy--anticoagulation has important limitations in acute stroke patients: almost impossible to be used in cerebral haemorrhage and a great risk for the development of haemorrhagic transformation in cerebral infarction. The fact that other prevention strategies have limited value requires an estimation of effectivity-risk ratio in venous thromboembolism prevention in stroke. Venous thromboembolism prevention in stroke patients is necessary because of a greater risk for venous thromboembolism in these patients according to the nature of illness and functional disability, but also a problem because of limited possibility to recommend the proper medicament according to the risk of serious complications. The necessity of preventing venous thromboembolism and estimation of effectivity-risk ratio in stroke patients, beside plenty of studies and consensus conferences, remain individual and often very difficult.

Atrial fibrillation (AF) is the most common clinically-significant arrhythmia in the adult population, and it is a strong independent risk factor for cerebrovascular accidents. Patients with non-valvular AF are five times more likely to suffer a stroke. Despite the clear recommendations for anticoagulant therapy, many clinicians are still reluctant to provide routine oral anticoagulation to patients with AF, despite the potential clinical benefits. To compare Polish and European populations of patients with AF and the every-day practice of stroke prevention in Poland and in the rest of Europe. We analysed the baseline data from the two first cohorts of patients enrolled in the GARFIELD-AF registry (an ongoing prospective, multicentre, international registry of patients newly diagnosed with AF) in Poland and in the rest of Europe. Polish AF patients are generally younger (median age 67 years in both cohorts vs. 73 in cohort 1 in the rest of Europe and 72 in cohort 2), but they carry a burden of more concomitant diseases. There are some noticeable differences in stroke prevention between Poland and the rest of Europe. The use of vitamin K antagonists (VKAs) is generally higher in other European countries in both cohorts (in Poland 41.7% in cohort 1 and 36.9% in cohort 2 vs. 55.5% in cohort 1 and 41.9% in cohort 2 in the rest of Europe). Meanwhile, it is generally more common in Poland to treat patients with both VKAs and antiplatelets (in cohort 1 20.4% of patients in Poland received vs. 12.0% in the rest of Europe). A total of 5.6% of patients in cohort 1 in Poland receive no antithrombotic treatment (it means: no VKA, oral factor Xa or thrombin inhibitors, antiplatelets), meanwhile in other countries it amounts to 8.5%. The usage of non-vitamin K oral anticoagulants is growing in Poland similarly to the other European countries. The GARFIELD-AF registry data shows how distant everyday clinical practice is from the guidelines. It shows that still in Poland, as well

Severity of acute vascular illness may have changed in the last decades due to improvements in primary and secondary prevention. Population-based data on the severity of acute ischemic cerebrovascular disease are sparse. We aimed to examine incidence, characteristics and severity of acute ischemic cerebrovascular disease in a well-defined population. All patients admitted with transient ischemic attack (TIA) or acute ischemic stroke from March 1, 2007, to February 29, 2008, with residence in the Aarhus area, were included. Incidence rates and characteristics of TIA and ischemic stroke were compared. TIA accounted for 30%, TIA and minor stroke combined for 65% of all acute ischemic cerebrovascular events. Age-adjusted incidence rates of TIA and ischemic stroke were 72.2/100,000 and 129.5/100,000 person-years, respectively. TIA patients were younger than stroke patients (66.3 vs. 72.7 years; p < 0.001). Atrial fibrillation, previous myocardial infarction and previous stroke were significantly more frequent in stroke patients; no differences in other baseline characteristics were found. Minor events are the most common in ischemic cerebrovascular disease, and may constitute a larger proportion than previously reported. TIA and stroke patients share many characteristics; however, TIA patients are younger and have fewer manifestations of atherosclerotic diseases, indicating a high potential for secondary prevention.

Mild stroke is the most common cause for thrombolysis exclusion in patients acutely presenting to the hospital. Thrombolysis administration in this subgroup is highly variable among different clinicians and institutions. We aim to study the predictors of thrombolysis in patients with mild ischemic stroke in the FL-PR CReSD registry (Florida-Puerto Rico Collaboration to Reduce Stroke Disparities). Among 73 712 prospectively enrolled patients with a final diagnosis of ischemic stroke or TIA from January 2010 to April 2015, we identified 7746 cases with persistent neurological symptoms and National Institutes of Health Stroke Scale ≤5 who arrived within 4 hours of symptom onset. Multilevel logistic regression analysis with generalized estimating equations was used to identify independent predictors of thrombolytic administration in the subgroup of patients without contraindications to thrombolysis. We included 6826 cases (final diagnosis mild stroke, 74.6% and TIA, 25.4%). Median age was 72 (interquartile range, 21); 52.7% men, 70.3% white, 12.9% black, 16.8% Hispanic; and median National Institutes of Health Stroke Scale, 2 (interquartile range, 3). Patients who received thrombolysis (n=1281, 18.7%) were younger (68 versus 72 years), had less vascular risk factors (hypertension, diabetes mellitus, and dyslipidemia), had lower risk of prior vascular disease (myocardial infarction, peripheral vascular disease, and previous stroke), and had a higher presenting median National Institutes of Health Stroke Scale (4 versus 2). In the multilevel multivariable model, early hospital arrival (arrive by 0-2 hours versus ≥3.5 hours; odds ratio [OR], 8.16; 95% confidence interval [CI], 4.76-13.98), higher National Institutes of Health Stroke Scale (OR, 1.87; 95% CI, 1.77-1.98), aphasia at presentation (OR, 1.35; 95% CI, 1.12-1.62), faster door-to-computed tomography time (OR, 1.81; 95% CI, 1.53-2.15), and presenting to an academic hospital (OR, 2.02; 95% CI, 1.39-2.95) were

Purpose Both stroke and chronic atrial fibrillation (AF) are common in dialysis patients, but uncertainty exists in the incidence of new strokes and the risk conferred by chronic AF. Methods A cohort of dually-eligible (Medicare & Medicaid) incident dialysis patients was constructed. Medicare claims were used to determine the onset of chronic AF, which was specifically treated as a time-dependent covariate. Cox proportional hazards models were used to model time to stroke. Results Of 56,734 patients studied, 5629 (9.9%) developed chronic AF. There were 22.8 ischemic and 5.0 hemorrhagic strokes per 1000 patient-years, a ratio of approximately 4.5:1. Chronic AF was independently associated with time to ischemic (HR 1.26, 99% CI’s 1.06 – 1.49, P = 0.0005), but not hemorrhagic, stroke. Race was strongly associated with hemorrhagic stroke: African-Americans (HR 1.46, 99% CI’s 1.08 – 1.96), Hispanics (HR 1.64, 99% CI’s 1.16 – 2.31), and others (HR 1.76, 99% CI’s 1.16 – 2.78) had higher rates than did Caucasians (P < 0.001 for all). Conclusions Chronic AF has a significant, but modest, association with ischemic stroke. Race/ethnicity is strongly associated with hemorrhagic strokes. The proportion of strokes due to hemorrhage is much higher than in the general population. PMID:23332588

To document the narratives of nursing staff and patients in a Thailand Rehabilitation Centre where complementary therapies are used and to discuss perceived progress of these stroke patients. Specific complementary therapies used at this Rehabilitation Centre include Thai massage and herbal therapies. Whilst there has been a small amount of quantitative research on stroke patients and complementary therapies there has been no qualitative research on the experience of stroke patients and the use of complementary therapies. Qualitative pilot study using narrative inquiry and discourse analysis framed by poststructural theory. Six stroke patients were interviewed about their involvement in complementary therapy practice and treatments and their experiences of these therapies in rehabilitation. This study represents a reflective mining of patients' stories and captures the main theme of changes in stroke patients' embodiment and a main discourse of attending to and enabling progress. Throughout the storylines there are many other discourses such as hope, desire, helplessness, despair, fear, motivation, gratefulness, gladness and fragility. Threaded throughout the stroke patients' stories of their rehabilitation there is a layering of discourses involving tensions and a longing to overcome their disability. There are twists and detours in their stories that show the complexity of the illness experience. Progress is not straightforward with a quick recovery. Many contexts or variables influence progress such as spatiality, temporality and people. What is offered here is the reality of the rehabilitation process for stroke patients. Through the use of narrative inquiry the contexts of people, spatiality (environment) and temporality (time) are an important part of rehabilitation process. © 2011 Blackwell Publishing Ltd.

Purpose To evaluate the influence of patient's weight on rehabilitation outcomes in first-event stroke patients. Design Retrospective, observational comparative study. 102 first-time stroke male and female patients admitted to the 52-bed neurology rehabilitation department in a rehabilitation hospital were included in the study. Body mass index (BMI), Functional Independence Measure (FIM) on admission and at discharge, as well as the delta-FIM (FIM on admission - FIM at discharge) were evaluated. The Kruskal-Wallis test was used to compare the FIM and the NIHSS scores between BMI groups (normal, overweight, moderate and severe obesity). Results A statistically significant negative correlation (rho = -0.20, p = 0.049) was found between FIM change and BMI, that remained significant after adjustments for age, sex and hospitalisation days. No difference was found between groups in FIM or NIHSS change between BMI groups. Conclusions In sub-acute post-stroke patients undergoing rehabilitation in rehabilitation hospital, BMI was negatively associated with the improvement of functional parameters. Patients' BMI should be taken into consideration when predicting rehabilitation outcome for stroke patients. Further investigations are needed to identify the functional parameters affected by the patients' BMI. Implications for Rehabilitation In sub-acute post-stroke patients undergoing rehabilitation in rehabilitation hospital, BMI was negatively associated with the improvement of functional parameters. Patients' BMI should be taken into consideration when predicting rehabilitation outcome for stroke patients. New rehabilitation strategies should be designed to improve the functional outcomes of rehabilitation of obese patients.

Complementary and alternative medicine (CAM) is commonly used by persons with stroke throughout the world, particularly in Asia. The objectives of this study were to determine the frequency of CAM use and the factors that predict the use of CAM in stroke patients. This study was carried out in the stroke units of Christian Medical College, Ludhiana, and Sree Chitra Tirunal Institute for Medical Sciences and Technology, Thiruvananthapuram, India, from June 2010 to December 2010. Participants were interviewed using a structured questionnaire (≥ 6 months post stroke). Outcomes were assessed using a modified Rankin Scale (mRS). Three hundred fourteen stroke patients were interviewed; mean age was 57.4 ± 12.9 years, and 230 (73.2%) patients were men. Of 314 patients, 114 (36.3%) had used the following CAM treatments: ayurvedic massage, 67 (59.3%); intravenous fluids, 22 (19.5%); herbal medicines, 17 (15%); homeopathy, 15 (13.3%); witchcraft, 3 (2.7%); acupuncture, 3 (2.7%); opium intake, 10 (8.8%); and other nonconventional treatments, 10 (8.8%). Patients with severe stroke (P < .0001), limb weakness (P < .0001), dysphagia (P = .02), dyslipidemia (P = .007), hypertension (P = .03), or hemorrhagic stroke (P<.0001) and patients with poor outcome (mRS >2;P < .0001) often used CAM treatments. More than one-third of the patients in this study opted for CAM. Presence of limb weakness, dysphagia, dyslipidemia, hypertension, hemorrhagic stroke, severe stroke, and poor outcome predicted the use of CAM.

To clinically assess neurogenic dysphagia, and to correlate its presence with demographic features, different stroke risk factors, anatomical arterial territorial stroke types, and pathological stroke types. Seventy-two stroke inpatients were studied between July 2007 and February 2008, at the Departments of Medicine and Neurology at Al-Yarmouk Teaching Hospital, Baghdad, and Rizgary Teaching Hospital, Erbil, Iraq. All patients were assessed using the Mann Assessment of Swallowing Ability score (MASA), Modified Rankin Scale, and the Stroke Risk Scorecard. All patients were reassessed after one month. There were 40 males and 32 females. Sixty-eight patients had ischemic stroke, and 4 had primary intracerebral hemorrhage (ICH). According to the MASA score, 55% of anterior circulation stroke (ACS) cases were associated with dysphasia, and 91% of lateral medullary syndrome cases were associated with dysphagia. Fifty-six percent of ACS dysphagic cases improved within the first month. Forty percent of dysphagic patients died in the one month follow up period, and in most, death was caused by aspiration pneumonia. We observed no significant differences regarding demographic features of dysphagia. Dysphagia can be an indicator of the severity of stroke causing higher mortality and morbidity in affected patients. It was not related to the stroke risk factors and the type of stroke. It is essential from a prognostic point of view to assess swallowing, and to treat its complications early.

To analyze how acupuncture therapy affects balance in patients experiencing their first stroke and to identify the stroke group with greatest improvement in balance after acupuncture intervention. Retrospective case-control study. Ward of a medical university hospital. A total of 629 stroke patients were enrolled initially; 345 patients met the study criteria and 132 were analyzed (66 each in the study and control groups). The study group received physiotherapy combined with acupuncture and the control group received only physiotherapy. The Postural Assessment Scale for Stroke patients (PASS) was used to evaluate balance. This balance scale system can be subdivided into static balance (PASS-MP, maintain posture) and dynamic balance (PASS-CP, change posture). This study revealed no statistically significant improvement of balance in the study group (t test). When patients with high Brunnstrom stage (Br stage) and low Br stage were analyzed separately, once again no statistical difference was detected between the study and control groups of those with high Br stage. However, among low-Br stage patients, the study group showed significant improvement in static balance (mean PASS-MP score±standard deviation: 4.7±3.7) compared with the control group (PASS-MP score: 2.8±2.7) (p<0.05). In first-ever stroke patients with a low Br stage, acupuncture therapy can improve static balance during rehabilitation. However, the effect on balance was limited among high-Br stage patients. This study provides information valuable to patients with hemiplegic stroke because it suggests that acupuncture can be used to improve balance. A prospective double-blind, randomized, controlled study design is recommended for future studies in patients with hemiplegic stroke.

Demographic changes, increased awareness of vascular risk factors, better diagnostic, progress in medical care, and increasing primary stroke prevention influence the profile of patients admitted to stroke-units. Changes in patient population and stroke type have important consequences on outcome and management at stroke-units. Data from the national database of the Austrian Stroke Unit Registry were analyzed for time-trends in demography, risk factors, cause, and stroke severity. Data of 48 038 ischemic and 5088 hemorrhagic strokes were analyzed. Between 2003 and 2011, median age increased significantly for ischemic strokes from 68 to 71 years in men and from 76 to 78 years in women, respectively. Ischemic stroke patients showed significantly increased rates of hypertension, hypercholesterolemia, and atrial fibrillation. In hemorrhagic strokes an increase for hypercholesterolemia and cardiac diseases other than atrial fibrillation and myocardial infarction were only found in men. A small but significant decrease in stroke severity was found for ischemic strokes from 4 to 3 points on the National Institutes of Health Stroke Scale in men and from 5 to 4 in women, and for hemorrhagic strokes from 9 to 6 points in men and from 9 to 7 in women. Cardioembolic strokes increased slightly, whereas macroangiopathy decreased. Significant time trends were seen for characteristics of ischemic and hemorrhagic stroke patients admitted to acute stroke-units in Austria. These include trends for older age and toward milder strokes with more cardioembolic causes. This signals a need for increased resources for managing multimorbidity and enabling early mobilization.

Occipital stroke patients mainly showed cortical blindness and unilateral vision loss; memory is generally reserved. Recent reports from neuroimaging show the occipital lobe may be involved in the processing of implicit memory (IM), especially the perception type of IM processing. In this study, we explored the explicit memory (EM) and IM damage in occipital lobe stroke patients. A total of 25 occipital strokes and 29 years of age, educational level equivalent healthy controls (HCs), evaluated by using immediate recall, delayed recall, recognition for EM tasks, picture identification, and category exemplar generation for IM tasks. There was no significant difference between occipital stroke patients and HCs in EM tasks and category exemplar generation task. In the picture identification task, occipital lobe stroke group score was poorer than HC group, the results were statistically significant, but in the pictures identify rate, occipital stroke patients and normal control group had no significant difference. The occipital stroke patients may have IM damage, primarily damage the perception type of IM priming effects, which was unrelated with their cortical blindness.

The American Stroke Association recommends that Emergency Medical Service bypass acute stroke-ready hospital (ASRH)/primary stroke center (PSC) for comprehensive stroke centers (CSCs) when transporting appropriate stroke patients, if the additional travel time is ≤15 minutes. However, data on additional transport time and the effect on hospital census remain unknown. Stroke patients ≥20 years old who were transported from home to an ASRH/PSC or CSC via Emergency Medical Service in 2010 were identified in the Greater Cincinnati area population of 1.3 million. Addresses of all patients' residences and hospitals were geocoded, and estimated travel times were calculated. We estimated the mean differences between the travel time for patients taken to an ASRH/PSC and the theoretical time had they been transported directly to the region's CSC. Of 929 patients with geocoded addresses, 806 were transported via Emergency Medical Service directly to an ASRH/PSC. Mean additional travel time of direct transport to the CSC, compared with transport to an ASRH/PSC, was 7.9±6.8 minutes; 85% would have ≤15 minutes added transport time. Triage of all stroke patients to the CSC would have added 727 patients to the CSC's census in 2010. Limiting triage to the CSC to patients with National Institutes of Health Stroke Scale score of ≥10 within 6 hours of onset would have added 116 patients (2.2 per week) to the CSC's annual census. Emergency Medical Service triage to CSCs based on stroke severity and symptom duration may be feasible. The impact on stroke systems of care and patient outcomes remains to be determined and requires prospective evaluation. © 2017 American Heart Association, Inc.

Insulin resistance was common in patients with stroke. This study investigated the association between insulin resistance and outcomes in nondiabetic patients with first-ever acute ischemic stroke. Patients with ischemic stroke without history of diabetes mellitus in the ACROSS-China registry (Abnormal Glucose Regulation in Patients With Acute Stroke Across China) were included. Insulin resistance was defined as a homeostatis model assessment-insulin resistance (HOMA-IR) index in the top quartile (Q4). HOMA-IR was calculated as fasting insulin (μU/mL)×fasting glucose (mmol/L)/22.5. Multivariable logistic regression or Cox regression was performed to estimate the association between HOMA-IR and 1-year prognosis (mortality, stroke recurrence, poor functional outcome [modified Rankin scale score 3-6], and dependence [modified Rankin scale score 3-5]). Among the 1245 patients with acute ischemic stroke enrolled in this study, the median HOMA-IR was 1.9 (interquartile range, 1.1-3.1). Patients with insulin resistance were associated with a higher mortality risk than those without (adjusted hazard ratio, 1.68; 95% confidence interval, 1.12-2.53; P =0.01), stroke recurrence (adjusted hazard ratio, 1.57, 95% confidence interval, 1.12-2.19; P =0.008), and poor outcome (adjusted odds ratio, 1.42; 95% confidence interval, 1.03-1.95; P =0.03) but not dependence after adjustment for potential confounders. Higher HOMA-IR quartile categories were associated with a higher risk of 1-year death, stroke recurrence, and poor outcome ( P for trend =0.005, 0.005, and 0.001, respectively). Insulin resistance was associated with an increased risk of death, stroke recurrence, and poor outcome but not dependence in nondiabetic patients with acute ischemic stroke. © 2017 American Heart Association, Inc.

Stroke in young adults represented 6.1% of all strokes, 5.7% of transient ischaemic attacks, 5.8% of cerebral infarctions and 8.4% of brain haemorrhages. However, reported minimal frequency of cardioembolic (2.1%) and atherothrombotic (3.4%) infarctions, accounted for 5.9% of lacunar and for 10.7% of essential infarctions and showed a maximum frequency in those infarctions of unusual aetiology (36%). Factors independently associated with stroke in young adults were cigarette smoking (OR 4.23; 95% CI 3.02-5.93; P=.000), unusual aetiology (OR 4.97; 95% CI 3.15-7.84; P=.000), headache (OR 4.57; 95% CI 2.59-8.07; P=.000), alcohol abuse (OR 3.93; 95% CI 2.46-6.29; P=.000), oral contraceptives (OR 14.07; 95% CI 2.37-83.40; P=.004), atrial fibrillation (OR 0.15; 95% CI 0.08-0.28; P=.000), arterial hypertension (OR 0.43; 95% CI 0.33-0.57; P=.000), COPD (OR 0.20; 95% CI 0.09-0.44; P=.000), atherothrombotic infarction (OR 0.51; 95% CI 0.34-0.77; P=.001), female sex (OR 0.71; 95% CI 0.52-0.97; P=.029), diabetes mellitus (OR 0.66; 95% CI 0.46-0.98; P=.030), ischaemic heart disease (OR 0.56; 95% CI 0.33-0.95; P=.032) and intermittent claudication (OR 0.48; 95% CI 0.24-0.94; P=.033). Stroke in young adults is infrequent (6.1% of the total), but represents the highest frequency of cerebral infarcts of unusual aetiology (36%). We conclude that stroke in younger patients presents its own and differentiated clinical profile. Copyright © 2015 Elsevier España, S.L.U. All rights reserved.

A stroke often results in post-stroke dementia, a rapid decline in memory and intelligence causing dysfunctions in daily life. The Chinese medicine doctor uses 4 examinations of inspection, listening, smelling, and feeling to determine the Chinese medicine pattern (CMP). Therefore, the purpose of the present study was to investigate the CMP in patients with post-stroke dementia. A total of 101 stroke patients were examined, consistent with the DSM IV diagnostic criteria of the American Psychiatric Association, as well as the National Institute of Neurological Disorders and Stroke-Association International pour Ia Recherche et I'Enseignement en Neurosciences vascular dementia diagnostic criteria of post-stroke dementia. 100 patients (99.0%) were KEDP (kidney essence deficiency pattern, shèn jīng kuī xū zhèng, ), 83 patients were AHLYP (ascendant hyperactivity of liver yang pattern, gān yáng shàng kàng zhèng, ), 83 patients were QBDP (qi-blood deficiency pattern, qì xuè kuī xū zhèng, ), 81 patients were SBOCP (static blood obstructing the collaterals pattern, yū xuè zǔ luò zhèng, ), 72 patients were BSTRP (bowels stagnation turbidity retention pattern, fǔ zhì zhuó liú zhèng, ), 50 patients were FHIEP (fire heat interior excess pattern, huǒ rè nèi sheng zhèng, ), and 39 participants (38.6%) were PTOOP (phlegm turbidity obstructing the orifices pattern, tán zhuó zǔ qiào zhèng, ); one to 31 patients have at least 2 CMPs simultaneously. In conclusion, the most CMP is KEDP CMP in the post-stroke dementia patients, and one patient may have one or at least 2 CMPs simultaneously.

Nutritional status among stroke patients has received limited attention despite the fact, that it may have an influence on clinical outcome. Previous studies have estimated that 15-20 % of patients suffer from malnutrition in the acute phase of stroke, but so far no studies have focused on the late rehabilitation phase after stroke in the patients own home, where the attention on nutrition may be reduced. To determine the prevalence of malnutrition during 6 months of stroke rehabilitation, and to investigate the association between nutritional status, functional recovery, length of stay in hospital and infectious complications. 89 patients with ischemic stroke consecutively admitted to a geriatric stroke rehabilitation unit had their nutritional status evaluated in the hospital at 1 week and 5 weeks after stroke, and in their own home at 3 months and 6 months. Nutritional status was evaluated by body weight, body mass index (BMI), mid upper arm circumference (MAC), triceps skinfold thickness (TSF) and serum concentrations of albumin and transferrin. Malnutrition was defined if the patients had 2 or more abnormal nutritional variables. We found a significant increase in albumin from 1 week to 6 months (P < 0.0001), and a significant increase in transferrin form 5 weeks to 6 months (P < 0.05). There was no significant change in weight or BMI from 1 week to 6 months. The number of patients with 2 or more abnormal nutritional variables was 31 (35 %) at 1 week and was reduced to 20 (22 %) at 6 months. 35 % of elderly patients with ischemic stroke admitted to a geriatric rehabilitation unit were malnourished 1 week after stroke. Particularly serum proteins and body fat were affected. Follow-up of nutritional variables showed improvement for serum proteins, and 22 % of the patients were malnourished 6 months after stroke.

To analyze the association of stroke etiological subtypes with severity and outcomes at 3 and 12 months in patients ≤50 years. Observational study of patients admitted to a stroke unit (2007-2013). demographic data, vascular risk factors, comorbidities, severity on admission (NIHSS), and good functional outcome (mRS ≤ 1) at 3 and 12 months. We used multivariate analyses to evaluate the influence of stroke etiology on severity and outcomes. We included 214 patients, 58.3 % men, mean age 41.4 years. General linear models showed all etiologies were more severe than lacunar strokes (P < 0.05). Atherothrombotic strokes showed greater severity than those of undetermined and uncommon etiology, whereas cardioembolic strokes were more severe than cryptogenic. Taking into account specific etiologies, atherothrombotic strokes (B = 5.860; 95 % CI 2.979-8.751), cervical artery dissection (CAD) [B = 7.485; 95 % confidence interval (CI) 4.734-10.237], and atrial fibrillation (AF) strokes (B = 5.773; 95 % CI 2.704-8.132) were more severe than other etiologies. Logistic regression models showed that strokes of uncommon etiology, especially those not related to CAD, had a lower probability of good outcome at 3 months [odds ratio (OR) = 0.197; CI 95 % 0.044-0.873], whereas atherothrombotic strokes were associated with this probability at 12 months (OR = 0.187; 95 % CI 0.037-0.951; P = 0.007). In patients ≤50 years of age, strokes of atherothrombotic, cardioembolic (particularly those due to AF), and uncommon etiology had a greater severity than the rest. Furthermore, strokes of uncommon etiology, especially those different from CAD, decreased the probability of a good outcome at 3 months, as did atherothrombotic strokes at 1 year.

Background: Encouragement of stroke patients to resume driving is important to promote their reintegration into the community. Limited rehabilitation has been performed in this regard, owing to lack of specific knowledge on the part of medical staff. To establish an effective support program for stroke patients who wish to resume driving, we propose comprehensive training by medical staff using a driving simulator. Methods: A survey of stroke patients admitted to the Tokyo Metropolitan Rehabilitation Hospital was first performed. A questionnaire was sent to 525 patients. Of 218 responses, the answers of 118 patients who had been driving before their stroke were analyzed. More than 80% of stroke patients did not obtain enough information about resuming driving during their hospital stay, and 38.1% of patients would have liked to have had driving training with a simulator. From these results, we set out to determine the effect of driving training using a realistic and technically advanced driving simulator. Twenty-four stroke patients and 20 healthy controls were included in the study. Results: Repeat training with the simulator resulted in an increased ability to perform braking and an improvement in driving ability. The majority of stroke patients who had the mental and physical ability to drive a car were likely to be assessed as being able to resume driving as a result of the training program. Conclusion: This study indicates that comprehensive support by medical staff and provision of adequate information about resumption of driving and the opportunity for training on a driving simulator are likely to aid resumption of driving by stroke patients, thus enhancing their rehabilitation and social reintegration.

ABSTRACT Background Stroke patients commonly have impairments associated with reduction in functionality. Among these impairments, the motor impairments are the most prevalent. The functional profile of these patients living in the community who are users of the primary health-care services in Brazil has not yet been established Objective To describe the functional profile of stroke patients who are users of the primary health-care services in Brazil, looking at one health-care unit in the city of Belo Horizonte, Brazil. Method From medical records and home visits, data were collected regarding health status, assistance received following the stroke, personal and environmental contextual factors, function and disability, organized according to the conceptual framework of the International Classification of Functioning, Disability and Health (ICF). Test and instruments commonly applied in the assessment of stroke patients were used. Results Demographic data from all stroke patients who were users of the health-care unit (n=44, age: 69.23±13.12 years and 67±66.52 months since the stroke) participated of this study. Most subjects presented with disabilities, as changes in emotional function, muscle strength, and mobility, risks of falling during functional activities, negative self-perception of quality of life, and perception of the environment factors were perceived as obstacles. The majority of the patients used the health-care unit to renew drug prescriptions, and did not receive any information on stroke from health professionals, even though patients believed it was important for patients to receive information and to provide clarifications. Conclusion Stroke patients who used primary health-care services in Brazil have chronic disabilities and health needs that require continuous health attention from rehabilitation professionals. All of these health needs should be considered by health professionals to provide better management as part of the integral care

Stroke comprises the leading cause of death in Greece, and more than 40% of the overall lifetime cost for stroke care, represents the acute phase hospitalization. The aim of the present study was to assess the resource utilization and estimate the costs for treatment of stroke patients in an Acute Stroke Unit (ASU). Patients with first-ever stroke treated in the ASU of an academic hospital in Athens during 2003-2009 were included in the analysis. The National Institutes of Health Stroke Scale (NIHSS), and the modified Rankin Scale (mRS) were employed to assess the neurological impairment on admission and the handicap at discharge, respectively. The cost categories measured were: diagnostic investigations, medications, medical and nursing staff, and overhead costs. A generalized linear model was used to predict the mean cost per patient, based on the clinical characteristics of the patients on admission, and during their hospitalization. In total, 784 patients were included in the analysis, with mean age of 72.2 (11.2) and mean length of hospital stay of 12.3 (9.5) days. The mean cost per patient was estimated at €2,864 (2,198), and the mean cost per day at €244 (54). The relevant cost for the mildly handicapped patients was €1,573 (625), while for the severely handicapped patients it was €4,136 (2,538). Delayed discharge was associated with a mean cost of €362 (634) per patient, while the cost for the acute phase management of the patients was €2,445 (2,471). The neurological impairment on admission (NIHSS score) and the delayed discharge, were strong predictors of the mean cost per patient. The costs for treatment of stroke patients in an ASU comprise a significant burden in Greece. Further research should be performed to explore the long-term costs for the treatment of the disease at a nation-wide level. Copyright © 2015 Elsevier B.V. All rights reserved.

Sexual function in post-stroke patients: considerations for rehabilitation.

Rosenbaum, Talli; Vadas, Dor; Kalichman, Leonid

2014-01-01

While the rehabilitation goals of post-stroke patients include improving quality of life and returning to functional activities, the extent to which sexual activity is addressed as part of the standard rehabilitation process is unknown. Moreover, the specific sexual concerns of stroke patients, including the effect of stroke on intimate relationships and sexuality of the partner, the ability to physically engage in sex, and the effect of psychological components such as role identity, depression, and anxiety on sexuality, all warrant examination by rehabilitation professionals. The aim of this study is to examine the existing literature on sexuality and stroke patients in order to better understand how the sexual lives of stroke patients and their partners are affected and to provide recommendations to rehabilitation professionals for addressing sexuality as part of treatment. Narrative review, PubMed, PEDro, ISI Web of Science, and Google Scholar databases (inception-December 2012) were searched for the key words "stroke," "sexual dysfunction," "sexuality," "quality of life," and their combination. All relevant articles in English and secondary references were reviewed. We report the results of the literature review. Sexual dysfunction and decreased sexual satisfaction are common in the post-stroke population and are related to physical, psychosocial, and relational factors. However, they are not adequately addressed in post-stroke rehabilitation. As sexual function is an important component to quality of life and activities of daily living, physicians and rehabilitation specialists, including physical, occupational, and speech therapists, should receive training in addressing sexuality in the treatment of post-stroke patients. Sexologists and sex therapists should be an integral part of the rehabilitation team. © 2013 International Society for Sexual Medicine.

Background and Purpose Cancer patients are at increased risk of cardiovascular and cerebrovascular events. It is unclear whether cancer confers any additional risk for recurrent stroke or cardiovascular mortality after stroke. Methods This was a single center, observational study of 1,105 consecutive Chinese ischemic stroke patients recruited from a large stroke rehabilitation unit based in Hong Kong. We sought to determine whether patients with cancer are at higher risk of recurrent stroke and cardiovascular mortality. Results Amongst 1,105 patients, 58 patients (5.2%) had cancer, of whom 74% were in remission. After a mean follow-up of 76±18 months, 241 patients developed a recurrent stroke: 22 in patients with cancer (38%, annual incidence 13.94%/year), substantially more than those without cancer (21%, 4.65%/year) (p<0.01). In a Cox regression model, cancer, age and atrial fibrillation were the 3 independent predictors of recurrent stroke with a hazard ratio (HR) of 2.42 (95% confidence interval (CI): 1.54–3.80), 1.01 (1.00–1.03) and 1.35 (1.01–1.82) respectively. Likewise, patients with cancer had a higher cardiovascular mortality compared with those without cancer (4.30%/year vs. 2.35%/year, p = 0.08). In Cox regression analysis, cancer (HR: 2.08, 95% CI: 1.08–4.02), age (HR: 1.04, 95% CI 1.02–1.06), heart failure (HR: 3.06, 95% CI 1.72–5.47) and significant carotid atherosclerosis (HR: 1.55, 95% CI 1.02–2.36) were independent predictors for cardiovascular mortality. Conclusions Stroke patients with a past history of cancer are at increased risk of recurrent stroke and cardiovascular mortality. PMID:24523883

Wake-up stroke (WUS) is defined when the exact time of the beginning of the symptoms cannot be determined, for the deficits are perceived upon awakening. Sleep alterations are important risk factors for stroke and cardiovascular diseases. This study evaluates the characteristics of patients with and without WUS, the presence of daytime sleepiness, and associated risk factors. Patients with ischemic stroke were investigated about the presence of WUS. Clinical and demographic characteristics were evaluated. Stroke severity was studied by the National Institutes of Health Stroke Scale (NIHSS) and the Modified Rankin Scale (MRS), and daytime sleepiness severity was studied by the Epworth Sleepiness Scale (ESS). Seventy patients (57.1% men) aged from 32 to 80 years (58.5±13.3) were studied. WUS was observed in 24.3%. Arterial hypertension (67.1%), type 2 diabetes (27.1%), and hyperlipidemia (22.8%) were frequent. Type 2 diabetes and sedentary lifestyle were more common in patients with WUS (p<0.05). Overall, mild, moderate or very few symptoms of stroke (NIHSS<5) were predominant (62.3%). Among all cases, 20% had excessive daytime sleepiness (ESS>10). No differences were found between patients with and without WUS as regards stroke severity or excessive daytime sleepiness. Patients with excessive daytime sleepiness were younger and had more sedentary lifestyle (p<0.05). Individuals with previous history of heavy drinking had more daytime sleepiness (p=0.03). Wake-up stroke occurs in approximately 25% of stroke cases. In this study, patients with WUS had more diabetes and sedentary lifestyle. Daytime sleepiness is frequent and is associated with sedentary lifestyle and heavy drinking.

To assess the knowledge of stroke in the general public in the Gulf Cooperation Council (GCC) countries. The Arabian Gulf is a rapidly developing part of the world with major changes in the lifestyle that can increase the risk of stroke. To design effective stroke treatment and prevention strategies, an assessment of the public knowledge of stroke is required. A cross-sectional community-based survey was conducted at primary health care centers (PHCs), in urban and semi-urban areas, of the GCC countries (Qatar, Saudi Arabia, Kuwait, Bahrain, the United Arab Emirates, Oman) on the level of stroke awareness in the general public. Health care workers completed 3,750 face-to-face interviews. 1,089 (29.0%) were familiar with the term 'stroke', and 29.3% considered the age group 30-50 at the highest risk for stroke. The commonest risk factors identified were hypertension (23.1%) and smoking (27.3%). People who did not know the term stroke had a higher incidence of diabetes, hypertension, and had more than one risk factor (p < 0.05). The most frequently identified stroke symptoms were weakness (23%) and speech problems (21.7%). Of those who recognized stroke, blockage of blood vessels was identified as the commonest cause of stroke (22%) followed by tension/worrying (20%). Doctors and nurses were regarded as the best source of stroke information (70%). In the univariate comparison, younger age (p < 0.001), higher level of education (p < 0.001), and female gender (p = 0.008) better predicted stroke recognition. In a multivariate logistic regression analysis, the level of education, monthly income and smoking were independent variables predicting stroke knowledge. The majority of the patients had not even heard the term stroke. Stroke knowledge was poorest among the groups that were at the highest risk for stroke. Stroke education has to focus on the high-risk groups, particularly the younger population. The health care workers at the PHCs and hospitals will need

The mixed units that place lucid and dementia patients in same rooms have been viewed to benefit the dementia patients. However, many studies report negative attitudes of lucid residents towards mixed units, and there is a scarcity of research which explores the experiences of lucid residents while sharing rooms with the dementia patients in extended care homes. Currently many special care nursing facilities have mixed units in Korea, suggesting a need to examine their effects especially on cognitively lucid patients. To explore lived experiences of stroke patients who were sharing rooms with patients with dementia in a nursing home. It was a qualitative study applying a phenomenological method to explore the experiences of stroke patients. Data were collected in a specialized nursing home in Korea. The nursing home provides free medical and nursing care to persons suffering either from dementia or stroke. Fourteen participants without cognitive deficit and who were sharing rooms with dementia patients were recruited through a purposive sampling. In-depth interviews Stroke patients sharing rooms with dementia patients were being seriously affected by intense, deeply disturbing, and persistent experiences. The experiences themselves seemed to evolve over time as each patient struggled on one's own to try to make sense out of what were happening. The stroke patients ended up having a sense of resignation and anger realizing that they had no power to change the policy or the situation. The stroke patients also were distraught about what were happening to themselves - change of their own character, continuous fear of becoming demented, and becoming to devalue life. They also became indifferent to others, and seemed to have lost motivation for activity resulting in a decreased or low activity level. Several personal and environmental factors were identified that tended to increase the level of suffering. We suggest that the whole concept of mixed units require further

To describe patient perspectives of aerobic exercise during inpatient stroke rehabilitation, including their self-efficacy and beliefs towards exercise, as well as their perceptions of barriers. A survey was conducted at three Canadian rehabilitation centres to evaluate individuals' (N = 33) self-efficacy and outcome expectations for exercise. In addition, patient perceptions of other people recovering from stroke, social support, and aerobic exercise as part of rehabilitation were assessed. Thirty-two people completed the survey. Of these, 97% were willing to participate in aerobic exercise 5.9 ± 8.8 days after admission to inpatient rehabilitation. While outcome expectations for exercise were high, participants reported lower self-efficacy for exercise. Patients reported barriers related to the ability to perform exercise (other health problems (i.e., arthritis), not being able to follow instructions and physical impairments) more often than safety concerns (fear of falling). The lack of support from a spouse and family were commonly identified, as was a lack of information on how to perform aerobic exercise. Patients with stroke are willing to participate in aerobic exercise within a week after admission to inpatient rehabilitation. However, they perceive a lack of ability to perform aerobic exercise, social support from family and information as barriers. Implications for rehabilitation Aerobic exercise is recognized as part of comprehensive stroke rehabilitation. There is a need to better understand patient perspectives to develop and implement more effective interventions early after stroke. Patients lack confidence in their ability to overcome barriers early after stroke. Patients are concerned with their ability to perform exercise, fall risk, lack of support from a spouse and family, and limited information on aerobic exercise. There is a need to reinforce education with practical experience in structured aerobic exercise programs that show

Abstract Dermatologic diseases are not traditional risk factors of stroke, but recent studies show atopic dermatitis, psoriasis, and bullous skin disease may increase the risk of stroke and other cardiovascular diseases. No previous studies have focused on the association between contact dermatitis and stroke. We established a cohort comprised of 48,169 contact dermatitis patients newly diagnosed in 2000–2003 and 96,338 randomly selected subjects without the disorder, frequency matched by sex, age, and diagnosis year, as the comparison cohort. None of them had a history of stroke. Stroke incidence was assessed by the end of 2011 for both cohorts. The incidence stroke was 1.1-fold higher in the contact dermatitis cohort than in the comparison cohort (5.93 vs 5.37 per 1000 person-years, P < 0.01). The multivariable Cox method analyzed adjusted hazard ratios (aHRs) were 1.12 (95% confidence interval [CI], 1.05–1.19) for all stroke types and 1.12 (95% CI, 1.05–1.20) for ischemic stroke and 1.11 (95% CI, 0.94–1.30) for hemorrhagic stroke. The age-specific aHR of stroke for contact dermatitis cohort increased with age, from 1.14 (95% CI, 1.03–1.27) for 65 to 74 years; to 1.27 (95% CI, 1.15–1.42) for 75 years and older. The aHR of stroke were 1.16 (95% CI, 1.07–1.27) and 1.09 (95% CI, 1.00–1.18) for men and women, respectively. This study suggests that patients with contact dermatitis were at a modestly increased risk of stroke, significant for ischemic stroke but not for hemorrhagic stroke. Comorbidity, particularly hypertension, increased the hazard of stroke further. PMID:28272195

Development, Implementation, and Evaluation of a Telemedicine Service for the Treatment of Acute Stroke Patients: TeleStroke

Background Health care service based on telemedicine can reduce both physical and time barriers in stroke treatments. Moreover, this service connects centers specializing in stroke treatment with other centers and practitioners, thereby increasing accessibility to neurological specialist care and fibrinolytic treatment. Objective Development, implementation, and evaluation of a care service for the treatment of acute stroke patients based on telemedicine (TeleStroke) at Virgen del Rocío University Hospital. Methods The evaluation phase, conducted from October 2008 to January 2011, involved patients who presented acute stroke symptoms confirmed by the emergency physician; they were examined using TeleStroke in two hospitals, at a distance of 16 and 110 kilometers from Virgen del Rocío University Hospital. We analyzed the number of interconsultation sheets, the percentage of patients treated with fibrinolysis, and the number of times they were treated. To evaluate medical professionals’ acceptance of the TeleStroke system, we developed a web-based questionnaire using a Technology Acceptance Model. Results A total of 28 patients were evaluated through the interconsultation sheet. Out of 28 patients, 19 (68%) received fibrinolytic treatment. The most common reasons for not treating with fibrinolysis included: clinical criteria in six out of nine patients (66%) and beyond the time window in three out of nine patients (33%). The mean “onset-to-hospital” time was 69 minutes, the mean time from admission to CT image was 33 minutes, the mean “door-to-needle” time was 82 minutes, and the mean “onset-to-needle” time was 150 minutes. Out of 61 medical professionals, 34 (56%) completed a questionnaire to evaluate the acceptability of the TeleStroke system. The mean values for each item were over 6.50, indicating that respondents positively evaluated each item. This survey was assessed using the Cronbach alpha test to determine the reliability of the

Wake-up stroke (WUS) accounts for up to 29.6% of ischemic strokes, but its mechanisms are poorly understood. The purpose of this study is to identify risk factors and characteristics of WUS. Seven-two ischemic strokes were classified as WUS or non-WUS. Collected were demographic information, medical history, cholesterol profile, and stroke characteristics including severity (National Institutes of Health Stroke Scale [NIHSS]) and mechanism (Trial of Org 10172 in Acute Stroke Treatment criteria). Subjects completed questionnaires screening for sleep apnea (Berlin questionnaire) and assessing sleep characteristics. There were 72 ischemic strokes, of which 28 WUS (38.9%). WUS and non-WUS patients were similar in regard to stroke risk factors. WUS patients tended to be African American and were significantly younger. WUS was significantly more likely to result from small-vessel disease mechanism (42.9% versus 14.0%; P=.006) and tended to be less severe WUS (NIHSS score 3 [1, 4] versus 4 [2, 11]; P=.13) than non-WUS. Groups did not differ in regard to scoring positively on the Berlin questionnaire, but WUS sufferers were more likely to snore frequently (90.5% versus 70.0%, P=.08). The lipid profile was significantly worse in WUS compared with non-WUS (low-density lipoprotein 124.6±38.4 versus 103.7±36.8; P=.03; cholesterol to high-density lipoprotein ratio 5.2±1.6 versus 4.3±1.6; P=.02). WUS is more likely to result from small-vessel disease mechanism. Poorer cholesterol profile and frequent snoring may contribute to WUS. Published by Elsevier Inc.

Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). We evaluated the efficacy and safety of tofacitinib 5 or 10 mg twice daily (BID), in patients with moderate to severe RA, aged ≥65 and <65 years. Data were pooled from five Phase 3 trials and, separately, from two open-label long-term extension (LTE) studies (data cut-off April, 2012). Patients received tofacitinib, or placebo (Phase 3 only), with/without conventional synthetic DMARDs (mainly methotrexate). Clinical efficacy outcomes from Phase 3 studies were evaluated at Month 3. Safety evaluations using pooled Phase 3 data (Month 12) and pooled LTE data (Month 24) compared exposure-adjusted incidence rates (IRs; with 95% confidence intervals [CIs]), in older versus younger patients. In Phase 3 and LTE studies, 15.3% (475/3111) and 16.1% (661/4102) of patients, respectively, were aged ≥65 years. Consequently, exposure to tofacitinib was lower in older versus younger patients in Phase 3 (259.2 vs. 1554.9 patient years [pt-yrs]) and LTE (962.1 vs. 5071.7 pt-yrs) studies. Probability ratios for ACR responses and HAQ-DI improvement from baseline ≥0.22 (Month 3) favoured tofacitinib and were similar in older and younger patients, with overlapping CIs. IRs for SAEs and discontinuations due to AEs were generally numerically higher in older versus younger patients, irrespective of treatment. Older patients receiving tofacitinib 5 or 10 mg BID had a similar probability of ACR20 or ACR50 response and, due to comorbidities, a numerically higher risk of SAEs and discontinuations due to AEs compared with younger patients.

To test the hypothesis that stroke and systemic embolic events (SEE) in the stroke prevention using an oral thrombin inhibitor in atrial fibrillation (SPORTIF) III and V trials are different between paroxysmal and persistent atrial fibrillation (AF). Data analysis from two cohorts of patients enrolled in the prospective SPORTIF III and V clinical trials (n = 7329); 836 subjects (11.4%) with paroxysmal AF [mean age 70.1 years (SD = 9.5)] were compared with 6493 subjects with persistent AF for this ancillary study. The annual event rates for stroke/SEE are 1.73% for persistent AF and 0.93% for paroxysmal AF. In a multivariate analysis, after adjusting for stroke risk factors, gender and aspirin usage, the differences remained statistically significant with a higher hazard ratio (HR) for stroke/SEE in persistent AF [vs. paroxysmal AF, HR 1.87, 95% confidence interval (CI) 1.04-3.36; P = 0.037]. In 'high risk' patients (with >or=2 stroke risk factors) annual event rates for stroke/SEE were 2.08% for persistent AF and 1.27% for paroxysmal AF (adjusted HR = 1.68, 95% CI 0.91-3.1, P = 0.098). Elderly patients had annual event rates for stroke/SEE of 2.38% for persistent AF and 1.13% for paroxysmal AF (adjusted HR = 2.27, 95% CI 0.92-5.59, P = 0.075). Vitamin K antagonist (VKA)-naive paroxysmal AF patients had a 1.89%/year stroke/SEE rate, compared with 0.61% for previous VKA takers (HR = 0.33, 95% CI 0.11-1.01, P = 0.052). In this large clinical trial cohort of anticoagulated AF patients, those with paroxysmal AF had stroke rates which were lower than for patients with persistent AF, although both groups had broadly similar stroke risk factors. Subjects with paroxysmal AF at 'high risk' had stroke/SEE rates that were not significantly different to persistent AF subjects.

Background Little is known about the prognosis of resistant hypertension (RH) in Asian population. This study aimed to evaluate the impacts of RH in Taiwanese patients with hypertension, and to ascertain whether patient characteristics influence the association of RH with adverse outcomes. Methods and Results Patients aged ≥45 years with hypertension were identified from the National Health Insurance Research Database. Medical records of 111,986 patients were reviewed in this study, and 16,402 (14.6%) patients were recognized as having RH (continuously concomitant use of ≥3 anti-hypertensive medications, including a diuretic, for ≥2 years). Risk of major adverse cardiovascular events (MACE, a composite of all-cause mortality, acute coronary syndrome, and stroke [included both fatal and nonfatal events]) in patients with RH and non-RH was analyzed. A total of 11,856 patients experienced MACE in the follow-up period (average 7.1±3.0 years). There was a higher proportion of females in the RH group, they were older than the non-RH (63.1 vs. 60.5 years) patients, and had a higher prevalence of cardiovascular co-morbidities. Overall, patients with RH had higher risks of MACE (adjusted HR 1.17; 95%CI 1.09–1.26; p<0.001). Significantly elevated risks of stroke (10,211 events; adjusted HR 1.17; 95%CI 1.08–1.27; p<0.001), especially ischemic stroke (6,235 events; adjusted HR 1.34; 95%CI 1.20–1.48; p<0.001), but not all-cause mortality (4,594 events; adjusted HR 1.06; 95%CI 0.95–1.19; p = 0.312) or acute coronary syndrome (2,145 events; adjusted HR 1.17; 95%CI 0.99–1.39; p = 0.070) were noted in patients with RH compared to those with non-RH. Subgroup analysis showed that RH increased the risks of stroke in female and elderly patients. However, no significant influence was noted in young or male patients. Conclusions Patients with RH were associated with higher risks of MACE and stroke, especially ischemic stroke. The risks were greater in female and

It is uncertain whether previous ischemic stroke within 3 months of receiving intravenous thrombolysis (tPA [tissue-type plasminogen activator]) for acute ischemic stroke (AIS) is associated with an increased risk of adverse outcomes. Using administrative claims data, we identified adults with AIS who received intravenous tPA at California, New York, and Florida hospitals from 2005 to 2013. Our primary outcome was intracerebral hemorrhage, and our secondary outcomes were unfavorable discharge disposition and inpatient mortality. We used logistic regression to compare rates of outcomes in patients with and without previous ischemic stroke within 3 months of intravenous tPA for AIS. We identified 36 599 AIS patients treated with intravenous tPA, of whom 568 (1.6%) had a previous ischemic stroke in the past 3 months. Of all patients who received intravenous tPA, the rate of intracerebral hemorrhage was 4.9% (95% confidence interval [CI], 4.7%-5.1%), and death occurred in 10.7% (95% CI, 10.4%-11.0%). After adjusting for demographics, vascular risk factors, and the Elixhauser Comorbidity Index, previous ischemic stroke within 3 months of thrombolysis for AIS was not associated with an increased risk of intracerebral hemorrhage (odds ratio, 0.9; 95% CI, 0.6-1.4; P =0.62), but was associated with an increased risk of death (odds ratio, 1.5; 95% CI, 1.2-1.9; P =0.001) and unfavorable discharge disposition (odds ratio, 1.3; 95% CI, 1.0-1.7; P =0.04). Among patients who receive intravenous tPA for AIS, recent ischemic stroke is not associated with an increased risk of intracerebral hemorrhage but is associated with a higher risk of death and unfavorable discharge disposition. © 2017 American Heart Association, Inc.

Transient ischemic attacks (TIA) and minor strokes are important risk factors for recurrent strokes. Current stroke risk prediction scores such as ABCD2, although widely used, lack optimal sensitivity and specificity. Elevated urinary albumin excretion predicts cardiovascular disease, stroke, and mortality. We explored the role of microalbuminuria (using albumin creatinine ratio (ACR)) in predicting recurrence risk in patients with TIA and minor stroke. Urinary ACR was measured on a spot sample in 150 patients attending a daily stroke clinic with TIA or minor stroke. Patients were followed up at day 7, 30, and 90 to determine recurrent stroke, cardiovascular events, or death. Eligible patients had a carotid ultrasound Doppler investigation. High-risk patients were defined as those who had an event within 90 days or had >50% internal carotid artery (ICA) stenosis. Fourteen (9.8%) recurrent events were reported by day 90 including two deaths. Fifteen patients had severe ICA stenosis. In total, 26 patients were identified as high risk. These patients had a higher frequency of previous stroke or hypercholesterolemia compared to low-risk patients (P = 0.04). ACR was higher in high-risk patients (3.4 [95% CI 2.2-5.2] vs. 1.7 [1.5-2.1] mg/mmol, P = 0.004), independent of age, sex, blood pressure, diabetes, and previous stroke. An ACR greater than 1.5 mg/mmol predicted high-risk patients (Cox proportional hazard ratio 3.5 (95% CI 1.3-9.5, P = 0.01). After TIA or minor stroke, a higher ACR predicted recurrent events and significant ICA stenosis. Incorporation of urinary ACR from a spot sample in the acute setting could improve risk stratification in patients with TIA and minor stroke.

Background Large clinical trials are lack of data on non‐vitamin K antagonist oral anticoagulants for acute stroke patients. Aim To evaluate the choice of oral anticoagulants at acute hospital discharge in stroke patients with nonvalvular atrial fibrillation and clarify the underlying characteristics potentially affecting that choice using the multicenter Stroke Acute Management with Urgent Risk‐factor Assessment and Improvement‐NVAF registry (ClinicalTrials.gov NCT01581502). Method The study included 1192 acute ischemic stroke/transient ischemic attack patients with nonvalvular atrial fibrillation (527 women, 77·7 ± 9·9 years old) between September 2011 and March 2014, during which three nonvitamin K antagonist oral anticoagulant oral anticoagulants were approved for clinical use. Oral anticoagulant choice at hospital discharge (median 23‐day stay) was assessed. Results Warfarin was chosen for 650 patients, dabigatran for 203, rivaroxaban for 238, and apixaban for 25. Over the three 10‐month observation periods, patients taking warfarin gradually decreased to 46·5% and those taking nonvitamin K antagonist oral anticoagulants increased to 48·0%. As compared with warfarin users, patients taking nonvitamin K antagonist oral anticoagulants included more men, were younger, more frequently had small infarcts, and had lower scores for poststroke CHADS 2, CHA 2 DS 2‐VASc, and HAS‐BLED, admission National Institutes of Health stroke scale, and discharge modified Rankin Scale. Nonvitamin K antagonist oral anticoagulants were started at a median of four‐days after stroke onset without early intracranial hemorrhage. Patients starting nonvitamin K antagonist oral anticoagulants earlier had smaller infarcts and lower scores for the admission National Institutes of Health stroke scale and the discharge modified Rankin Scale than those starting later. Choice of nonvitamin K antagonist oral anticoagulants was independently associated with 20‐day or

Because of a shortage of stroke specialists, many outlying or "spoke" hospitals initiate intravenous (IV) thrombolysis using telemedicine or telephone consultation before transferring patients to a regional stroke center (RSC) hub. We analyzed complications and outcomes of patients treated with IV tissue plasminogen activator (tPA) using the "drip and ship" approach compared to those treated directly at the RSC. A retrospective review of our Get With the Guidelines Stroke (GWTG-Stroke) database from 01/2003 to 03/2008 identified 296 patients who received IV tPA within 3 hours of symptom onset without catheter-based reperfusion. GWTG-Stroke definitions for symptomatic intracranial (sICH), systemic hemorrhage, discharge functional status, and destination were applied. Follow-up modified Rankin Score was recorded when available. Of 296 patients, 181 (61.1%) had tPA infusion started at an outside spoke hospital (OSH) and 115 (38.9%) at the RSC hub. OSH patients were younger with fewer severe strokes than RSC patients. Patients treated based on telestroke were more frequently octogenarians than patients treated based on a telephone consult. Mortality, sICH, and functional outcomes were not different between OSH versus RSC and telephone versus telestroke patients. Among survivors, mean length of stay was shorter for OSH patients but discharge status was similar and 75% of patients walked independently at discharge. Outcomes in OSH "drip and ship" patients treated in a hub-and-spoke network were comparable to those treated directly at an RSC. These data suggest that "drip and ship" is a safe and effective method to shorten time to treatment with IV tPA.

What do nurses and therapists think about the positioning of stroke patients?

PubMed

Rowat, A M

2001-06-01

At present, there are a number of different positioning strategies for stroke patients, but these are mainly based on clinical experience rather than research. Prior to developing a study to evaluate the effect of positioning on outcome after stroke, it was important to establish if nurses in our hospital had given much thought to the positioning of stroke patients. This study aimed to explore whether nurses working on the stroke unit at a Scottish teaching hospital held different views on the positioning of conscious and unconscious stroke patients to nurses working on other wards with stroke patients and therapists. Questionnaires on various aspects of patient positioning were sent to 150 nurses and 25 therapists working in five specialities where stroke patients are cared for in a large teaching hospital. Overall, the majority of nurses and therapists (74%) believed that the best position for conscious stroke patients was sitting in a chair. Also, 80% of them believed that the best position for unconscious stroke patients was lying on the nonparetic side. There was less of a consensus between nurses and therapists working in the five specialities as to whether it was appropriate for conscious or unconscious stroke patients to lie on their paretic side, lie supine or sit propped-up in bed in either a 30 or 70 degrees angle. The lack of consensus between nurses working in the five specialities is probably because at present there is little research to guide nursing practices for the positioning of stroke patients. Therefore, research to confirm which positions improves or hinders outcome after stroke is essential. Indeed, positioning is a simple inexpensive strategy, which could have a substantial public health impact, as stroke is so common.

Auditory disability due to impaired auditory processing (AP) despite normal pure-tone thresholds is common after stroke, and it leads to isolation, reduced quality of life and physical decline. There are currently no proven remedial interventions for AP deficits in stroke patients. This is the first study to investigate the benefits of personal frequency-modulated (FM) systems in stroke patients with disordered AP. Fifty stroke patients had baseline audiological assessments, AP tests and completed the (modified) Amsterdam Inventory for Auditory Disability and Hearing Handicap Inventory for Elderly questionnaires. Nine out of these 50 patients were diagnosed with disordered AP based on severe deficits in understanding speech in background noise but with normal pure-tone thresholds. These nine patients underwent spatial speech-in-noise testing in a sound-attenuating chamber (the "crescent of sound") with and without FM systems. The signal-to-noise ratio (SNR) for 50% correct speech recognition performance was measured with speech presented from 0° azimuth and competing babble from ±90° azimuth. Spatial release from masking (SRM) was defined as the difference between SNRs measured with co-located speech and babble and SNRs measured with spatially separated speech and babble. The SRM significantly improved when babble was spatially separated from target speech, while the patients had the FM systems in their ears compared to without the FM systems. Personal FM systems may substantially improve speech-in-noise deficits in stroke patients who are not eligible for conventional hearing aids. FMs are feasible in stroke patients and show promise to address impaired AP after stroke. Implications for Rehabilitation This is the first study to investigate the benefits of personal frequency-modulated (FM) systems in stroke patients with disordered AP. All cases significantly improved speech perception in noise with the FM systems, when noise was spatially separated from the

Poststroke depression (PSD) is one of the most important long-term adverse psychosocial consequences in stroke survivors. Our objective was to assess the prevalence of PSD in Brazilian stroke patients and identify significant associated factors. A cross-sectional study of stroke patients consecutively admitted for rehabilitation was conducted. The patients were evaluated by means of the NIH Stroke Scale, Mini-Mental State Examination, Barthel Index, Lawton Scale, modified Rankin Scale, Hospital Anxiety and Depression Scale (HADS), Geriatric Depression Scale (GDS) and MOS-Short Form 36. Patients with a HADS-depression subscale score > or = 11 and/or GDS score > or = 8 were classified as depressed. Three hundred stroke survivors were assessed (mean age: 56.3 years; 51.7% males). Half (46.7%) of the stroke patients had an m-RS score < or = 2. The proportion of stroke patients who scored > or = 11 points on the HADS-depression and HADS-anxiety subscales were 19.2 and 23.7%, respectively. One third (29.7%) had a GDS mean score > or = 8. The GDS scores significantly correlated (p < 0.0001) with the HADS-depression (r = 0.51) and HADS-anxiety subscales (r = 0.54). The prevalence of mood disorders was significantly higher in females than in males (24.8 vs. 14.2%; x(2), p = 0.03). PSD was significantly associated (p < 0.0001) with work status (housewife), education level, lower social and cognitive functioning, dependence in the instrumental activities of daily living and presence of diabetes in the multivariable regression analysis (R adjusted = 0.32). PSD was highly prevalent in the chronic phase of stroke. Early detection and recognition of associated risk factors is important to treat and prevent PSD in a rehabilitation setting. 2009 S.

Stroke is a global burden. It is not known whether patients who are most at risk of stroke (recurrent stroke or recurrent transient ischaemic attack) have enough knowledge of stroke risk factors and warning signs. The aim of this study was to assess the knowledge of stroke risk factors and warning signs in this high-risk population. We performed a cross-sectional questionnaire-based study of patients with recurrent stroke or recurrent TIA admitted to Srinagarind Hospital and Khon Kaen Hospital, Thailand. A total of 140 patients were included in the study (age 65.6 ± 11.3 years [mean ± SD], 62 females). Using an open-ended questionnaire, nearly one-third of patients (31.4%) could not name any risk factors for stroke. The most commonly recognized risk factors were hypertension (35%), dyslipidemia (28.6%), and diabetes (22.9%). Regarding stroke warning signs, the most commonly recognized warning signs were sudden unilateral weakness (61.4%), sudden trouble with speaking (25.7%), and sudden trouble with walking, loss of balance, or dizziness (21.4%). Nineteen patients (13.6%) could not identify any warning signs. The results showed that knowledge of stroke obtained from open-ended questionnaires is still unsatisfactory. The healthcare provider should provide structured interventions to increase knowledge and awareness of stroke in these patients.

Although important data on the prognosis and rehabilitation outcome in stroke patients have been reported, data on functional recovery according to stroke subtypes are limited. This retrospective study aimed to evaluate functional outcome in patients with middle cerebral artery (MCA) stroke-the most common subtype of ischemic stroke. The records of stroke patients that underwent the rehabilitation program at our brain injury rehabilitation service between January 2007 and December 2008 were reviewed, and those with MCA stroke were included in the study. Patient demographic and clinical data, and Barthel Index (BI) and Functional Independence Measure (FIM) scores at admission and discharge were collected. The study included 80 MCA stroke patients with a mean age of 63.54 years. FIM and BI scores improved significantly post rehabilitation (P<0.05). Age was negatively correlated with both BI and FIM scores at admission and discharge. Length of stay was not correlated with improvement in BI or FIM scores during hospitalization. The patients that had ≤1 month of inpatient rehabilitation had similar outcomes as those that had >1 month of inpatient rehabilitation (P>0.05). Length of time after stroke onset was not correlated with BI or FIM scores at admission. Regardless of initial functional status, prediction of discharge functional status was misleading. Physiatrists should keep in mind that functional improvement does not always increase with duration of inpatient therapy. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

This study aimed to evaluate the effectiveness of the delirium prevention interventions recommended by the Delirium Prevention Guidelines for Elderly Stroke Patients (DPGESP). The DPGESP comprises nine dimensions with 28 interventions, including risk factor assessment, orientation disorder prevention, sleeping pattern maintenance, sensory interventions, constipation, dehydration, hypoxia and infection prevention, pain management, and appropriate nutrition maintenance. This quasi-experimental study used a nonequivalent control group and a pretest-posttest design. The experimental and control groups each included 54 patients, and the participants were elderly patients who were admitted to the stroke unit. The study outcomes were the delirium incidence and severity, stroke impact, and length of hospitalization. Posttest values for delirium incidence, severity, stroke impact, and length of hospitalization were significantly improved in the experimental group. Implementation of the DPGESP had beneficial effects on the delirium incidence and severity, stroke impact, and length of hospitalization among elderly patients admitted to a stroke unit.

Summary Introduction: In the literature, the incidence of oropharyngeal dysphagia in patients with cerebrovascular accident (AVE) ranges 20–90%. Some studies correlate the location of a stroke with dysphagia, while others do not. Objective: To correlate brain injury with dysphagia in patients with stroke in relation to the type and location of stroke. Method: A prospective study conducted at the Hospital de Clinicas with 30 stroke patients: 18 women and 12 men. All patients underwent clinical evaluation and swallowing nasolaryngofibroscopy (FEES®), and were divided based on the location of the injury: cerebral cortex, cerebellar cortex, subcortical areas, and type: hemorrhagic or transient ischemic. Results: Of the 30 patients, 18 had ischemic stroke, 10 had hemorrhagic stroke, and 2 had transient stroke. Regarding the location, 10 lesions were in the cerebral cortex, 3 were in the cerebral and cerebellar cortices, 3 were in the cerebral cortex and subcortical areas, and 3 were in the cerebral and cerebellar cortices and subcortical areas. Cerebral cortex and subcortical area ischemic strokes predominated in the clinical evaluation of dysphagia. In FEES®, decreased laryngeal sensitivity persisted following cerebral cortex and ischemic strokes. Waste in the pharyngeal recesses associated with epiglottic valleculae predominated in the piriform cortex in all lesion areas and in ischemic stroke. A patient with damage to the cerebral and cerebellar cortices from an ischemic stroke exhibited laryngeal penetration and tracheal aspiration of liquid and honey. Conclusion: Dysphagia was prevalent when a lesion was located in the cerebral cortex and was of the ischemic type. PMID:25991951

Patients with any type of stroke managed in organized inpatient (stroke unit) care are more likely to survive, return home, and regain independence. However, it is uncertain whether these benefits apply equally to patients with intracerebral hemorrhage and ischemic stroke. We conducted a secondary analysis of a systematic review of controlled clinical trials comparing stroke unit care with general ward care, including only trials published after 1990 that could separately report outcomes for patients with intracerebral hemorrhage and ischemic stroke. We performed random-effects meta-analyses and tested for subgroup interactions by stroke type. We identified 13 trials (3570 patients) of modern stroke unit care that recruited patients with intracerebral hemorrhage and ischemic stroke, of which 8 trials provided data on 2657 patients. Stroke unit care reduced death or dependency (risk ratio [RR], 0.81; 95% confidence interval [CI], 0.471-0.92; P=0.0009; I2=60%) with no difference in benefits for patients with intracerebral hemorrhage (RR, 0.79; 95% CI, 0.61-1.00) than patients with ischemic stroke (RR, 0.82; 95% CI, 0.70-0.97; Pinteraction=0.77). Stroke unit care reduced death (RR, 0.79; 95% CI, 0.64-0.97; P=0.02; I2=49%) to a greater extent for patients with intracerebral hemorrhage (RR, 0.73; 95% CI, 0.54-0.97) than patients with ischemic stroke (RR, 0.82; 95%, CI 0.61-1.09), but this difference was not statistically significant (Pinteraction=0.58). Patients with intracerebral hemorrhage seem to benefit at least as much as patients with ischemic stroke from organized inpatient (stroke unit) care.

Intraoperative hypotension may contribute to perioperative strokes. We therefore tested the hypothesis that intraoperative hypotension is associated with perioperative stroke. After institutional review board approval for this case-control study, we identified patients who had nonneurological, noncardiac, and noncarotid surgery under general anesthesia at the Cleveland Clinic between 2005 and 2011 and experienced a postoperative stroke. Control patients not experiencing postoperative stroke were matched in a 4-to-1 ratio using propensity scores and restriction to the same procedure type as stroke patients. The association between intraoperative hypotension, measured as time-integrated area under a mean arterial pressure (MAP) of 70 mm Hg, and postoperative stroke was assessed using zero-inflated negative binomial regression. Among 106 337 patients meeting inclusion criteria, we identified 120 who had confirmed postoperative stroke events based on manual chart review. Four-to-one propensity matching yielded a final matched sample of 104 stroke cases and 398 controls. There was no association between stroke and intraoperative hypotension. Stroke patients were not more likely than controls to have been hypotensive (odds ratio, 0.49 [0.18-1.38]), and among patients with intraoperative hypotension, stroke patients did not experience a greater degree of hypotension than controls (ratio of geometric means, 1.07 [0.76-1.53]). In our propensity score-matched case-control study, we did not find an association between intraoperative hypotension, defined as MAP < 70 mm Hg, and postoperative stroke.

For stroke patients, intensive nutritional management is an important and effective component of inpatient rehabilitation. Accordingly, acute care hospitals must detect and prevent malnutrition at an early stage. Blood transthyretin levels are widely used as a nutritional monitoring index in critically ill patients. Here, we had analyzed the relationship between the transthyretin levels during the acute phase and Functional Independence Measure in stroke patients undergoing convalescent rehabilitation. We investigated 117 patients who were admitted to our hospital with acute ischemic or hemorrhagic stroke from February 2013 to October 2015 and subsequently transferred to convalescent hospitals after receiving acute treatment. Transthyretin concentrations were evaluated at 3 time points as follows: at admission, and 5 and 10 days after admission. After categorizing patients into 3 groups according to the minimum transthyretin level, we analyzed the association between transthyretin and Functional Independence Measure. In our patients, transthyretin levels decreased during the first 5 days after admission and recovered slightly during the subsequent 5 days. Notably, Functional Independence Measure efficiency was significantly associated with the decrease in transthyretin levels during the 5 days after admission. Patients with lower transthyretin levels had poorer Functional Independence Measure outcomes and tended not to be discharged to their own homes. A minimal transthyretin concentration (<10 mg/dL) is predictive of a poor outcome in stroke patients undergoing convalescent rehabilitation. In particular, an early decrease in transthyretin levels suggests restricted rehabilitation efficiency. Accordingly, transthyretin levels should be monitored in acute stroke patients to indicate mid-term rehabilitation prospects. Copyright © 2017 National Stroke Association. Published by Elsevier Inc.

The objective of this nationwide study was to analyze how functional status and socioeconomic status affect return to work (RTW) among younger patients with first-time stroke in a Sweden. This register-based cohort study included employed patients aged 25-55 with first-time stroke between 2008 and 2011 and primary outcome was RTW within 1 year after stroke. Data regarding functional status and employment status were retrieved from the Swedish Stroke Register, Riksstroke, and socioeconomic data (income, education, and country of birth) from Statistics Sweden. We included 2539 patients who had answered the question on RTW, and 1880 (74.0%) had RTW within 12 months. Patients with low income (69.9% in lowest income group vs 79.9% in highest group, P<.001), patients born in countries outside the Nordic countries (Sweden 75.5%, Nordic countries 74.3%, European countries 61.7%, other countries 57.3%, P<.001), and the youngest patients (25-34, 63.1%; 35-44, 75.9%; 45-55, 74.3%; P=.008) were less likely to RTW. Pain, low mood, and answering the questionnaire with help were more common in low socioeconomic groups, and when adjusting for these variables, together with age and sex, income and country of birth were no longer independent predictors for RTW. Patients with low socioeconomic status less often RTW 1 year after stroke.Impaired functional status after stroke is more common in patients with lower socioeconomic status and mediates socioeconomic differences in RTW. Improvement of functional status should be targeted to facilitate RTW among stroke patients with low socioeconomic status. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The risk of stroke in patients with short-run atrial tachyarrhythmia (AT) remains unclear. This study aimed to investigate the relationship between short-run AT and the stroke and the use of the CHA 2 DS 2 -VASc score for the risk stratification. From the registry of 24-hour Holter monitoring, 5342 subjects without known atrial fibrillation or stroke were enrolled. Short-run AT was defined as episodes of supraventricular ectopic beats <5 seconds. There were 1595 subjects (29.8%) with short-run AT. During the median follow-up period of 9.0 years, 494 subjects developed new-onset stroke. Patients with short-run AT had significantly higher stroke rates compared with patients without short-run AT (11.4% versus 8.3%; P <0.001). In patients with short-run AT, the number of strokes per 100 person-years for patients with CHA 2 DS 2 -VASc score of 0 and 1 were 0.23 and 0.67, respectively. However, the number of them for patients with CHA 2 DS 2 -VASc score of 2, 3, 4, and ≥5 were 1.62, 1.89, 1.30, and 2.91, respectively. In patients with CHA 2 DS 2 -VASc score of 0 or 1, age (>61 years old) and burden of premature atrial contractions (>25 beats/d) independently predicted the risk of stroke. In subgroup analyses, short-run AT patients were divided into 3 groups based on their CHA 2 DS 2 -VASc scores: low score (score of 0 [men] or 1 [women]; n=324), intermediate score (score of 1 [men] or 2 [women]; n=275), and high score (score of ≥2 [men] or ≥3 [women]; n=996). When compared with low score, intermediate and high scores were independent predictors for stroke (hazard ratio, 6.165; P <0.001 and hazard ratio, 8.577; P <0.001, respectively). Short-run AT increases the risk of stroke. Therefore, the CHA 2 DS 2 -VASc score could be used for the risk stratification. Age and burden of premature atrial contractions were independent predictors for stroke in patients with CHA 2 DS 2 -VASc score of 0 or 1. © 2017 American Heart Association, Inc.

Stroke is known to be associated with an increase in the risk for suicide. However, there are very few population-based studies investigating the risk of suicidal ideation and attempts in patients with stroke. The purpose of this study was to compare the risk of suicidal ideation and attempts between patients with stroke and population without stroke using nationwide survey data. Individual-level data were obtained from 228,735 participants (4560 with stroke and 224,175 without stroke) of the 2013 Korean Community Health Survey. Demographic characteristics, socioeconomic status, physical health status, and mental health status were compared between patients with stroke and population without stroke. Multivariable logistic regression was performed to investigate the independent effects of the stroke on suicidal ideation and attempts. Stroke patients had more depressive mood (12.6 %) than population without stroke (5.7 %, p < 0.001). Stroke patients experienced more suicidal ideation (24.4 %) and attempts (1.3 %) than population without stroke (9.8 and 0.4 %, respectively; both p < 0.001). Stroke was found to increase the risk for suicidal ideation (OR 1.65, 95 % CI 1.52-1.79) and suicidal attempts (OR 1.64, 95 % CI 1.21-2.22), adjusting for demographics, socioeconomic factors, and physical health and mental health factors. We found that stroke increased the risk for suicidal ideation and attempts, independent of other factors that are known to be associated with suicidality, suggesting that stroke per se may be an independent risk factor for suicidality.

Visual analogue scales (VAS) have been used for the subjective measurement of mood, pain, and health status after stroke. In this study we investigated how stroke-related impairments could alter the ability of subjects to answer accurately. Consent was obtained from 96 subjects with a clinical stroke (mean age, 72.5 years; 50 men) and 48 control subjects without cerebrovascular disease (mean age, 71.5 years; 29 men). Patients with reduced conscious level or severe dysphasia were excluded. Subjects were asked to rate the tightness that they could feel on the (unaffected) upper arm after 3 low-pressure inflations with a standard sphygmomanometer cuff, which followed a predetermined sequence (20 mm Hg, 40 mm Hg, 0 mm Hg). Immediately after each change, they rated the perceived tightness on 5 scales presented in a random order: 4-point rating scale (none, mild, moderate, severe), 0 to 10 numerical rating scale, mechanical VAS, horizontal VAS, and vertical VAS. Standard tests recorded deficits in language, cognition, and visuospatial awareness. Inability to complete scales with the correct pattern was associated with any stroke (P<0.001). There was a significant association between success using scales and milder clinical stroke subtype (P<0.01). Within the stroke group, logistic regression analysis identified significant associations (P<0.05) between impairments (cognitive and visuospatial) and inability to complete individual scales correctly. Many patients after a stroke are unable to successfully complete self-report measurement scales, including VAS.

Background Stroke rehabilitation improves functional recovery among stroke patients. However, little is known about clinical practice in China regarding the assessment and provision of rehabilitation among patients with acute ischemic stroke. Aims We examined the frequency and determinants of an assessment for rehabilitation among acute ischemic stroke patients from the China National Stroke Registry II. Methods Data for 19,294 acute ischemic stroke patients admitted to 219 hospitals from June 2012 to January 2013 were analyzed. The multivariable logistic regression model with the generalized estimating equation method accounting for in-hospital clustering was used to identify patient and hospital factors associated with having a rehabilitation assessment during the acute hospitalization. Results Among 19,294 acute ischemic stroke patients, 11,451 (59.4%) were assessed for rehabilitation. Rates of rehabilitation assessment varied among 219 hospitals (IQR 41.4% vs 81.5%). In the multivariable analysis, factors associated with increased likelihood of a rehabilitation assessment ( p < 0.05) included disability prior to stroke, higher NIHSS on admission, receipt of a dysphagia screen, deep venous thrombosis prophylaxis, carotid vessel imaging, longer length of stay, and treatment at a hospital with a higher number of hospital beds (per 100 units). In contrast, patients with a history of atrial fibrillation and hospitals with higher number of annual stroke discharges (per 100 patients) were less likely to receive rehabilitation assessment during the acute stroke hospitalization. Conclusions Rehabilitation assessment among acute ischemic stroke patients was suboptimal in China. Rates varied considerably among hospitals and support the need to improve adherence to recommended care for stroke survivors.

This study was designed to assess the effect of particular tools on the nutritional status of patients with stroke risk factors; to analyze these risk factors; to construct an assessment table; and to enable nurses to conduct fast and accurate assessment of the nutritional status of patients with stroke. Various nutritional assessment tools were employed to assess the nutritional status of stroke patients [(Nutritional Risk Screening 2002, NRS2002); (mini nutritional assessment, MNA), (subjective global assessment SGA), (malnutrition universal screening, MUST); (body composition, BCA)]. The leading disease-related factors of cerebral apoplexy were observed in patients with malnutrition. And a statistical analysis was conducted. The significant risk factors of cerebral apoplexy in malnourished patients older than 70 years were swallowing dysfunctions, disturbance of consciousness and reliance or half-reliance on feeding practices. The significant risk factors of malnutrition in patients with cerebral apoplexy were the decline in upper limb muscle strength, decline in the performance of various activities, loss of appetite and gastrointestinal symptoms. Disorders that affect the nutritional status of stroke patients can be used as evaluation tools, as described in the evaluation table. The clinical relevance of this study includes the following: to enable the clinical nursing staff to easily assess the patient's nutritional status in a timely manner; to improve compliance with nutritional evaluation; to provide clinical nutrition support to patients with stroke; and to provide a scientific basis for the improvement of the clinical outcomes of patients with cerebral apoplexy.

To determine the relation between rehabilitation intensity and poststroke mortality. Retrospective cohort study. Nationwide claims data. From Taiwan's National Health Insurance claims databases, patients (N=6737; mean age, 66.9y; 40.3% women) hospitalized between 2001 and 2013 for a first-ever stroke who had mild to moderate stroke and survived the first 90 days of stroke were enrolled. The intensity of rehabilitation therapy within 90 days after stroke was categorized into low, medium, or high based on the tertile distribution of the number of rehabilitation sessions. Long-term all-cause mortality. The Cox proportional hazard models with Bonferroni correction were used to assess the association between rehabilitation intensity and mortality, adjusting for age, comorbidities, stroke severity, and other covariates. Patients in the high-intensity group were younger but had a higher burden of comorbidities and greater stroke severity. During follow-up, the high-intensity group was associated with a significantly lower adjusted risk (hazard ratio [HR], .73; 95% confidence interval [CI], .63-.84) of mortality than the low-intensity group, whereas the medium-intensity group carried a similar risk of mortality (HR, 0.94; 95% CI, 0.84-1.06) compared with the low-intensity group. This association was not modified by stroke severity. Among patients with mild to moderate stroke severity, high-intensity rehabilitation therapy within the first 90 days was associated with a lower mortality risk than low-intensity therapy. Efforts to promote high-intensity rehabilitation therapy for this group of patients with stroke should be encouraged. Copyright © 2017 American Congress of Rehabilitation Medicine.

To evaluate occurrence of cerebellar stroke in Emergency Department (ED) presentations of isolated dizziness (dizziness with a normal exam and negative neurological review of systems). A 5-year retrospective study of ED patients presenting with a chief complaint of "dizziness or vertigo", without other symptoms or signs in narrative history or on exam to suggest a central nervous system lesion, and work-up included a brain MRI within 48h. Patients with symptoms commonly peripheral in etiology (nystagmus, tinnitus, gait instability, etc.) were included in the study. Patient demographics, stroke risk factors, and gait assessments were recorded. One hundred and thirty-six patients, who had a brain MRI for isolated dizziness, were included. There was a low correlation of gait assessment between ED physician and Neurologist (49 patients, Spearman's correlation r 2 =0.17). Based on MRI DWI sequence, 3.7% (5/136 patients) had acute cerebellar strokes, limited to or including, the medial posterior inferior cerebellar artery vascular territory. In the 5 cerebellar stroke patients, mean age, body mass index (BMI), hemoglobin A1c, gender distribution, and prevalence of hypertension were similar to the non-cerebellar stroke patient group. Mean LDL/HDL ratio was 3.63±0.80 and smoking prevalence was 80% in the cerebellar stroke group compared to 2.43±0.79 and 22% (respectively, p values<0.01) in the non-cerebellar stroke group. Though there was preselection bias for stroke risk factors, our study suggests an important proportion of cerebellar stroke among ED patients with isolated dizziness, considering how common this complaint is.

Risk factors for first stroke are well established, but less is known about risk factors for recurrent stroke. In the present analysis, we aimed to assess the effect of heart rate and other possible predictors of stroke in a hypertensive population with previous stroke or transient ischemic attack (TIA). The Valsartan Antihypertensive Long-Term Use Evaluation trial was a multicentre, double-masked, randomized controlled, parallel group trial comparing the effects of an angiotensin receptor blocker (valsartan) and a calcium channel blocker (amlodipine) in patients with hypertension and high cardiovascular risk. We used Cox proportional hazard models to investigate the effect of baseline variables on the risk of stroke. Quadratic terms of the continuous variables were entered in the models to test for linearity. Of 15,245 patients included in the trial, 3014 had a previous stroke or TIA at baseline and were included in the present analysis. Stroke recurrence occurred in 239 patients (7.9%) during a median of 4.5 years of follow-up. Resting heart rate (per 10 beats per minute; hazard ratio [HR], 2.78; 95% confidence interval [CI], 1.18-6.58) and diabetes mellitus at baseline (HR, 1.47; 95% CI, 1.03-2.10) were significantly associated with an increased risk of stroke recurrence in the multivariable analysis. In high-risk, hypertensive patients with previous stroke or TIA, resting heart rate was the strongest predictor of recurrent stroke. Copyright © 2014 National Stroke Association.

Impaired social function has been described in patients following stroke. The present study was designed to explore the degree of impairment in the ability to infer mental states in others, or cognitive and affective theory of mind, and empathy, in patients with stroke. A total of 34 patients with stroke were compared to 40 control subjects on tasks testing verbal and non-verbal theory of mind and empathy. Results indicated that patients with stroke were significantly impaired in both cognitive and affective theory of mind, even controlling for basic cognitive function and emotional processing. The patients with right stroke had poorer performance than those with left stroke on the cognitive component of non-verbal theory of mind. On the subscale of cognitive empathy, the right stroke group had poorer performance on perspective-taking than the control group. The right hemisphere may play an important role in decoding non-verbal cues to infer others' minds as well as the processing of empathy, especially the ability of perspective-taking. © 2014 The Authors.

Background: Renal impairment is regularly seen in hospitalized stroke patients, affecting the outcome of patients, as well as causing difficulties in their management. A prospective cohort study was conducted to assess the trend of renal function in hospitalized ischemic and haemorrhagic stroke patients. The incidence of renal impairment in these subgroups, the contributing factors and the need for renal replacement in renal impaired patients was evaluated. Methods: Alternate day renal function testing was performed in hospitalized stroke patients. Estimated glomerular filtration rate (e-GFR) was calculated and the trend of renal function in the two stroke subgroups (haemorrhagic and ischemic) was assessed, with renal impairment defined as e-GFR < 60mL/ minute per 1.73m 2 . Results: Among 52 patients, 25 had haemorrhagic stroke (mean age 59.81 ± 14.67) and 27 had ischemic stroke (mean age 56.12 ± 13.08). The mean e-GFR (mL/minute per 1.732m 2 ) at admission in the haemorrhagic stroke subgroup was 64.79 ± 25.85 compared to 86.04 ± 26.09 in the ischemic stroke subgroup (p=0.005). Sixteen out of 25 (64%) patients in the haemorrhagic stroke subgroup and 9 out of 27 (33.3%) patients in the ischemic subgroup developed renal impairment (p=0.027). The location of the bleed (p=0.8), volume of hematoma (p=0.966) and surgical intervention (p=0.4) did not predispose the patients to renal impairment. One out of 16 patients with haemorrhagic stroke (who eventually died), and 2 out of 9 patients with ischemic stroke required renal replacement. Conclusion : Renal impairment is commonly seen in stroke patients, more so in patients who suffered haemorrhagic strokes.  The impairment, however, is transient and rarely requires renal replacement therapy.

SMART syndrome (stroke-like migraine attacks after radiation therapy) is a rare condition that involves complex migraines with focal neurologic findings in patients following cranial irradiation for central nervous system malignancies. Little is known about the mechanisms behind the disorder, making successful treatment challenging. We report 2 new cases of SMART syndrome in pediatric patients as well as review all documented cases of the syndrome. Each of our 2 pediatric patients suffered multiple episodes. Attacks were characterized by severe headache, visual disturbance, aphasia, and weakness. Recovery occurred over several days to weeks. The data from all documented reports of SMART syndrome indicate a greater prevalence for male gender. An age-dependent pattern of onset was also observed, with a greater variability of syndrome onset in patients who received cranial irradiation at a younger age. SMART appears to be a reversible, recurrent long-term complication of radiation therapy with possible age- and gender-related influences.

Background and purpose There are limited data on the causes and severity of subsequent stroke in patients presenting initially with TIA or stroke attributed to intracranial arterial stenosis. Methods We evaluated the location, type (lacunar vs. non-lacunar), cause, and severity of stroke in patients who had an ischemic stroke endpoint in the Warfarin Aspirin Symptomatic Intracranial Disease (WASID) trial. Results Of the 569 patients enrolled in the WASID trial, 106 patients (18.6%) had an ischemic stroke during a mean follow-up of 1.8 years. Stroke occurred in the territory of the symptomatic artery in 77 (73%) of 106 patients. Among the 77 strokes in the territory, 70 (91%) were non-lacunar and 34 (44%) were disabling. Stroke out of the territory of the symptomatic artery occurred in 29 (27%) of 106 patients. Among these 29 strokes, 24 (83%) were non-lacunar, 14 (48%) were due to previously asymptomatic intracranial stenosis, and 9 (31%) were disabling. Conclusions Most subsequent strokes in patients with symptomatic intracranial artery stenosis are in the same territory and non-lacunar, and nearly half of the strokes in the territory are disabling. The most commonly identified cause of stroke out of the territory was a previously asymptomatic intracranial stenosis. Penetrating artery disease was responsible for a low number of strokes.

Epidemiology, pathophysiology, and treatment of hypertension in ischaemic stroke patients.

PubMed

Hisham, Nur Fatirul; Bayraktutan, Ulvi

2013-10-01

Stroke continues to be one of the leading causes of mortality and morbidity worldwide. There are 2 main types of stroke: ischaemic strokes, which are caused by obstruction of the blood vessels leading to or within the brain, and haemorrhagic strokes, which are induced by the disruption of blood vessels. Stroke is a disease of multifactorial aetiology that may develop as an end state in patients with serious vascular conditions--most notably, uncontrolled arterial hypertension--thereby necessitating the effective control of this risk factor to prevent stroke or its recurrence. This paper focuses specifically on the epidemiology and pathogenesis of ischaemic stroke mainly in chronically hypertensive patients and pays particular attention to the efficacy of a select group of routinely used major antihypertensive drugs (i.e., angiotensin-converting enzyme inhibitors, angiotensin II type 1 receptor blockers, and calcium channel blockers) in the treatment of strokes.

The importance of the patient's subjective experience in stroke rehabilitation.

PubMed

Prigatano, George P

2011-01-01

Kaufman's observation that the patients' reactions to their impairments and disabilities need to be addressed in stroke rehabilitation has been shown to be an accurate and perceptive statement. In this article, 3 levels of stroke rehabilitation are outlined, and the importance of focusing on the third level (the level of subjective experience) is emphasized. Identification of the patients' subjective experience allows one to understand what is most frustrating to them. After addressing those frustrations, patients are more eager to engage the rehabilitation process. Within the context of this rehabilitation process, helping patients clarify what their subjective or phenomenological state is as it relates to their stroke is crucial in having them not only engage the rehabilitation process, but ultimately find meaning in life in the face of their stroke. This can be a difficult task because patients often do not have the words to clarify what their inner psychological experiences are following a stroke. Helping to provide guidelines for this can result in a meaningful experience for both the patient and the therapists involved in their care.

Stroke is among the major causes of short- and long-term disability. This study aimed to understand the caregivers (CGs) stress in stroke survivors. A 22-item questionnaire was administered to 201 CGs of stroke survivors. The variables tested were physical and mental health, social support, financial, and personal problems. CGs were divided into Group A (Barthel index [BI] <75) and B (BI >75) according to patient's BI, according to gender (male and female CG) and relation; spouses (wife, husband), daughters, sons, daughter-in-law, grandchildren, and rest (father, mother, brother, sister, and in-laws). Data were analyzed using SPSS software version-21. Data were analyzed to determine which variables of the patient effects the CG stress. Majority of the CGs (74.62%) were females. 65% of CGs graded their burden as moderate to severe. 81% of CGs had left their work for caregiving. More than half of the CGs felt sleep disturbance and physical strain. Psychological instability and financial burdens were reported in 3/4 th of CGs. Group A CGs faced more sleep, financial, health, and social life disturbance. Patient's bladder and bowel problems, shoulder pain, patients noncooperative attitude for medication administration, and physiotherapy were more upsetting for Group A CGs. Female CGs were subjected to more sleep disturbance, physical and psychological stress, faced more difficulty regarding the patient's bladder, bowel, personal hygiene needs, and physiotherapy. Female CGs felt less motivated in caregiving than male CGs. Wives and daughters-in-law experienced more burden. Time spent and burden perceived was more by female CGs (χ 2 = 15.199, P = 0.002) than males (χ 2 = 11.931, P = 0.018); wives and daughters than other relations (χ 2 = 32.184, P = 0.000), (χ 2 = 35.162, P = 0.019). Our study showed that caregiving burden was predominantly shouldered by females CGs. CGs faced physical, psychological, and socioeconomic burden. The burden was more evident in female

Silent brain infarctions are associated with an increased risk of stroke in healthy individuals. Risk of recurrent stroke in patients with both symptomatic and silent brain infarction (SBI) has only been investigated in patients with cardioembolic stroke in the European Atrial Fibrillation Trial. We assessed whether patients with recent noncardioembolic stroke and SBI detected on MRI are at increased risk for recurrent stroke, other cardiovascular events, and mortality. The prevalence of SBI detected on MRI was assessed in 1014 patients enrolled in the imaging substudy of the Prevention Regimen for Effectively Avoiding Second Strokes (PRoFESS) trial. The primary outcome was first recurrence of stroke in patients with both symptomatic stroke and SBI in comparison with age- and sex-matched patients with stroke without SBI. Secondary outcomes were a combined vascular end point, other vascular events, and mortality. The 2 groups were compared using conditional logistic regression. Silent brain infarction was detected in 207 (20.4%) of the 1014 patients. Twenty-seven (13.0%) patients with SBI and 19 (9.2%) without SBI had a recurrent stroke (OR, 1.42; 95% CI, 0.79-2.56; P=0.24) during a mean follow-up of 2.5 years. Similarly, there was no statistically significant difference for all secondary outcome parameters between patients with SBI and matched patients without SBI. The presence of SBI in patients with recent mild noncardioembolic ischemic stroke could not be shown to be an independent risk factor for recurrent stroke, other vascular events, or a higher mortality rate.

Patients with acute stroke often do not seek immediate medical help, which is assumed to be driven by lack of knowledge of stroke symptoms. We explored the process of help seeking behavior in patients with acute stroke, evaluating knowledge about stroke symptoms, socio-demographic and clinical characteristics, and onset-to-alarm time (OAT). In a sub-study of the Preventive Antibiotics in Stroke Study (PASS), 161 acute stroke patients were prospectively included in 3 Dutch hospitals. A semi-structured questionnaire was used to assess knowledge, recognition and interpretation of stroke symptoms. With in-depth interviews, response actions and reasons were explored. OAT was recorded and associations with socio-demographic, clinical parameters were assessed. Knowledge about stroke symptoms does not always result in correct recognition of own stroke symptoms, neither into correct interpretation of the situation and subsequent action. In our study population of 161 patients with acute stroke, median OAT was 30 min (interquartile range [IQR] 10-150 min). Recognition of one-sided weakness and/or sensory loss (p = 0.046) and adequate interpretation of the stroke situation (p = 0.003), stroke at daytime (p = 0.002), severe stroke (p = 0.003), calling the emergency telephone number (p = 0.004), and transport by ambulance (p = 0.040) were associated with shorter OAT. Help seeking behavior after acute stroke is a complex process. A shorter OAT after stroke is associated with correct recognition of one-sided weakness and/or sensory loss, adequate interpretation of the stroke situation by the patient and stroke characteristics and logistics of stroke care, but not by knowledge of stroke symptoms.

We investigated the association of cerebral microbleeds (CMBs) with long-term mortality in patients with nonvalvular atrial fibrillation (NVAF) according to burden and distribution of CMBs. This was a retrospective, hospital-based, observational study. In total, 504 consecutive ischemic stroke patients with NVAF who underwent brain T2-weighted, gradient-recalled echo MRI were included. Data for the date and causes of death were based on the death certificates from the Korean National Statistical Office. We determined the association of the presence, burden, and distribution of CMBs with mortality from all-cause, ischemic heart disease, ischemic stroke, and hemorrhagic stroke. CMBs were found in 30.7% of patients (155/504). During a median follow-up of 2.5 years, 176 patients (34.9%) died (ischemic stroke, 81; hemorrhagic stroke, 12; ischemic heart disease, 32). Patients with CMBs died more frequently than those without (41.9% vs 31.8%, p = 0.028). After adjusting for age, sex, and other significant variables, the presence of multiple (≥5) CMBs was as an independent predictor for all-cause (hazard ratio [HR]: 1.99) and ischemic stroke (HR: 3.39) mortality. Patients with strictly lobar CMBs had an increased risk of hemorrhagic stroke mortality (HR: 5.91). The presence and burden of CMBs were associated with increased mortality in stroke patients with NVAF. Patients with lobar CMBs were at increased risk of death due to hemorrhagic stroke. The diagnosis of CMBs is of value in predicting long-term prognosis in stroke patients with NVAF. © 2014 American Academy of Neurology.

Comprehensive stroke systems of care include routing to the nearest designated stroke center hospital, bypassing non-designated hospitals. Routing protocols are implemented at the state or county level and vary in qualification criteria and determination of destination hospital. We surveyed all counties in the state of California for presence and characteristics of their prehospital stroke routing protocols. Each county's local emergency medical services agency (LEMSA) was queried for the presence of a stroke routing protocol. We reviewed these protocols for method of stroke identification and criteria for patient transport to a stroke center. Thirty-three LEMSAs serve 58 counties in California with populations ranging from 1,175 to nearly 10 million. Fifteen LEMSAs (45%) had stroke routing protocols, covering 23 counties (40%) and 68% of the state population. Counties with protocols had higher population density (1,500 vs. 140 persons per square mile). In the six counties without designated stroke centers, patients meeting criteria were transported out of county. Stroke identification in the field was achieved using the Cincinnati Prehospital Stroke Screen in 72%, Los Angeles Prehospital Stroke Screen in 7% and a county-specific protocol in 22%. California EMS prehospital acute stroke routing protocols cover 68% of the state population and vary in characteristics including activation by symptom onset time and destination facility features, reflecting matching of system design to local geographic resources.

The article represents results of a theoretical work in the field of nursing education, with the topic: Verbal Patient Information through Nurses--A Case of Stroke Patients. The literature review and analysis show that there is a shortage in (stroke) patient information generally and a lack of successful concepts and strategies for the verbal (stroke) patient information through nurses in hospitals. The authors have developed a theoretical basis for health information as a nursing intervention and this represents a model of health information as a "communicational teach-and-learn process", which is of general application to all patients. The health information takes place as a separate nursing intervention within a non-public, face-to-face communication situation and in the steps-model of the nursing process. Health information is seen as a learning process for patients and nurses too. We consider learning as information production (constructivism) and information processing (cognitivism). Both processes are influenced by different factors and the illness-situation of patients, personality information content and the environment. For a successful health information output, it is necessary to take care of these aspects and this can be realized through a constructivational understanding of didactics. There is a need for an evaluation study to prove our concept of health information.

Objective To determine factors associated with patients refusing IV t-PA for suspected acute ischemic stroke (AIS), and to compare the outcomes of patients who refused t-PA (RT) with those treated with t-PA. Methods Patients who were treated with and refused t-PA at our stroke center were identified retrospectively. Demographics, clinical presentation, and outcome measures were collected and compared. Clinical outcome was defined as excellent (mRS: 0–1), good (mRS: 0–2), and poor (mRS: 3–6). Results Over 7.5 years, thirty (4.2%) patients refused t-PA. There were no demographic differences between the treated and RT groups. The rate of RT decreased over time (OR 0.63, 95% CI 0.50 – 0.79). Factors associated with refusal included a later symptom onset to emergency department presentation time (OR 1.02, 95% CI 1.01 – 1.03), lower NIHSS (OR 1.11, 95% CI 1.03 – 1.18), a higher proportion of stroke mimics (OR 17.61, 95% CI 6.20 – 50.02) and shorter hospital stay (OR 1.32, 95% CI 1.09 – 1.61). Among patients who were subsequently diagnosed with ischemic stroke, only length of stay was significantly shorter for refusal patients (OR 1.37, 95% CI 1.06 – 1.78). After controlling for mild strokes and stroke mimics, clinical outcome was not different between the groups (OR 1.61, 95% CI 0.69 – 3.73). Conclusion The incidence of patients refusing t-PA has decreased over time, yet it may be a cause for t-PA under-utilization. Patients with milder symptoms were more likely to refuse t-PA. Refusal patients presented later to the hospital and had shorter hospital stays. One out six refusal patients (16.6%) had a stroke mimic. PMID:23227830

Strokes occur increasingly frequently in people aged 55 years or younger and present a problem of management and therefore of prognosis. The objective of this study was to determine the prognostic factors associated with hemorrhagic stroke in this population in Senegal. This retrospective study concerns 53 patients aged 16 to 55 years, hospitalized for hemorrhage stroke in the neurological department of Fann Teaching Hospital during 2010. The patients' mean age was 42.1 years (16 to 55 years) and the sex ratio 1.30 in favor of women. Hypertension was found in 62% of the patients, and 11% had a history of stroke. Hemiplegia was observed in 76%, associated more or less with impairment of consciousness (43%) and language (38%). Intraparenchymal hematomas were principally supratentorial (78%); only 15% were subtentorial (10% cerebellar and 5% in the brainstem). During the acute phase of hemorrhage, glycemic levels were high among one third of the patients. The mortality rate in our series was 43% and was highest among those of impaired consciousness and abnormal glycemic, cholesterol, and creatinemia levels. Neuropsychological sequelae occurred in 47% of all patients, including 83% of the survivors. Hemorrhagic stroke in people aged 55 years or younger is a public health problem. In view of the high mortality rate, effective control requires prevention of its risk factors and increased awareness of the danger of these factors and of the warning signs of stroke.

Initial stroke severity is one of the strongest predictors of eventual stroke outcome. However, predictors of initial stroke severity have not been well-described within a population. We hypothesized that poorer patients would have a higher initial stroke severity on presentation to medical attention. We identified all cases of hospital-ascertained ischemic stroke occurring in 2005 within a biracial population of 1.3 million. "Community" socioecomic status was determined for each patient based on the percentage below poverty in the census tract in which the patient resided. Linear regression was used to model the effect of socioeconomic status on stroke severity. Models were adjusted for race, gender, age, prestroke disability, and history of medical comorbidities. There were 1895 ischemic stroke events detected in 2005 included in this analysis; 22% were black, 52% were female, and the mean age was 71 years (range, 19-104). The median National Institutes of Health Stroke Scale was 3 (range, 0-40). The poorest community socioeconomic status was associated with a significantly increased initial National Institutes of Health Stroke Scale by 1.5 points (95% confidence interval, 0.5-2.6; P<0.001) compared with the richest category in the univariate analysis, which increased to 2.2 points after adjustment for demographics and comorbidities. We found that increasing community poverty was associated with worse stroke severity at presentation, independent of other known factors associated with stroke outcomes. Socioeconomic status may impact stroke severity via medication compliance, access to care, and cultural factors, or may be a proxy measure for undiagnosed disease states.

Improvements in acute care of stroke patients have decreased mortality, but survivors are still at increased risk of future vascular events and mitigation of this risk requires thorough assessment of the underlying factors leading to the stroke. The brain and eye share a common embryological origin and numerous similarities exist between the small vessels of the retina and brain. Recent population-based studies have demonstrated a close link between retinal vascular changes and stroke, suggesting that retinal photography could have utility in assessing underlying stroke risk factors and prognosis after stroke. Modern imaging equipment can facilitate precise measurement and monitoring of vascular features. However, use of this equipment is a challenge in the stroke ward setting as patients are frequently unable to maintain the required seated position, and pupil dilatation is often not feasible as it could potentially obscure important neurological signs of stroke progression. This small study investigated the utility of a novel handheld, nonmydriatic retinal camera in the stroke ward and explored associations between retinal vascular features and stroke risk factors. This camera circumvented the practical limitations of conducting retinal photography in the stroke ward setting. A positive correlation was found between carotid disease and both mean width of arterioles (r = .40, P = .00571) and venules (r = .30, P = .0381). The results provide further evidence that retinal vascular features are clinically informative about underlying stroke risk factors and demonstrate the utility of handheld retinal photography in the stroke ward.

Atrial fibrillation (AF) is reported to be a less frequent cause of ischemic stroke in China than in Europe and North America, but it is not clear whether this is due to underestimation. Our aim was to define the true frequency of AF-associated stroke, to determine the yield of 6-day Holter ECG to detect AF in Chinese stroke patients, and to elucidate predictors of newly detected AF. Patients with acute ischemic stroke or transient ischemic attack (TIA) were enrolled in a prospective, multicenter cohort study of 6-day Holter monitoring within 7 days after stroke onset at 20 sites in China between 2013 and 2015. Independent predictors of newly-detected AF were determined by multivariate analysis. Among 1511 patients with ischemic stroke and TIA (mean age 63 years, 33.1% women), 305 (20.2%) had either previously known (196, 13.0%) or AF newly-detected by electrocardiography (53, 3.5%) or by 6-day Holter monitoring (56/1262, 4.4%). A history of heart failure (OR = 4.70, 95%CI, 1.64-13.5), advanced age (OR = 1.06, 95%CI, 1.04-1.09), NIHSS at admission (OR = 1.06, 95%CI, 1.02-1.10), blood high density lipoprotein (HDL) (OR = 1.52, 95%CI, 1.09-2.13), together with blood triglycerides (OR = 0.64, 95%CI, 0.45-0.91) were independently associated with newly-detected AF. Contrary to previous reports, AF-associated stroke is frequent (20%) in China if systemically sought. Prolonged noninvasive cardiac rhythm monitoring importantly increases AF detection in patients with recent ischemic stroke and TIA in China. Advanced age, history of heart failure, and higher admission NIHSS and higher level of HDL were independent indicators of newly-detected AF. NCT02156765 (June 5, 2014).

Risk awareness and knowledge of patients with stroke: results of a questionnaire survey 3 months after stroke

Background Secondary prevention of stroke has been shown to dramatically reduce recurrence and has been described as suboptimal. Objective To analyse patients' awareness and knowledge about cerebrovascular risk factors (CVRF) and their influence on CVRF control. Methods Patients (n = 164) who were attending a stroke outpatient clinic for the first time after hospital discharge (3 months) for a first stroke were asked to answer a short questionnaire including questions on awareness and knowledge of CVRF, visits to a CVRF specialist, number of visits to a general practitioner, adherence to drug treatments, cigarette smoking and cessation. Results CVRF were spontaneously mentioned as relevant for their stroke by only13% of patients. A specialist was visited by only one‐third of the patients and a general practitioner was not visited at all by 27% of the patients since their stroke. Awareness was inversely correlated with older age and good recovery. More than half of the patients had high blood pressure (≥140 mmHg for systolic and ≥90 mmHg for diastolic values) at the time of follow‐up. These high values were correlated with poor awareness. Appropriate secondary stroke prevention measures were not received by one‐fourth of the patients; this was also correlated with poor awareness. Conclusions CVRF control is not optimal and is at least partially related to patients' awareness and knowledge and suboptimal medical follow‐up. Older patients and patients with excellent recovery are at particular risk for poor awareness and CVRF control. PMID:16549417

Older liver grafts have been considered in the past decade due to organ shortage. The aim was to compare outcomes after liver transplantation with either younger or older donors. Patients transplanted in our center between 2004 and 2014 with younger donors (younger than 60 years; n = 253) were compared with older donors (older than 75 years; n = 157). Multiorgan transplantations, split grafts, or non-heart-beating donors were not included. Donors in the older group were mostly women deceased from stroke, and only 3 patients had experienced cardiac arrest. Liver tests were significantly better in the older group than in the younger group. There was no difference regarding cold ischemia time, model for end-stage liver disease score, and steatosis. There was no significant difference regarding primary nonfunction and dysfunction, hepatic artery and biliary complications, and retransplantation rates. Graft survival was not different (65% and 64% in the older and younger groups, P = 0.692). Within the older group, hepatitis C infection, retransplantation, and emergency transplantation were associated with poor graft survival. Provided normal liver tests and the absence of cardiac arrest in donors, older liver grafts (>75 years) may be safely attributed to non-hepatitis C-infected recipients in the setting of a first and nonurgent transplantation.

Value-based health care aims to bring together patients and health systems to maximize the ratio of quality over cost. To enable assessment of healthcare value in stroke management, an international standard set of patient-centered stroke outcome measures was defined for use in a variety of healthcare settings. A modified Delphi process was implemented with an international expert panel representing patients, advocates, and clinical specialists in stroke outcomes, stroke registers, global health, epidemiology, and rehabilitation to reach consensus on the preferred outcome measures, included populations, and baseline risk adjustment variables. Patients presenting to a hospital with ischemic stroke or intracerebral hemorrhage were selected as the target population for these recommendations, with the inclusion of transient ischemic attacks optional. Outcome categories recommended for assessment were survival and disease control, acute complications, and patient-reported outcomes. Patient-reported outcomes proposed for assessment at 90 days were pain, mood, feeding, selfcare, mobility, communication, cognitive functioning, social participation, ability to return to usual activities, and health-related quality of life, with mobility, feeding, selfcare, and communication also collected at discharge. One instrument was able to collect most patient-reported subdomains (9/16, 56%). Minimum data collection for risk adjustment included patient demographics, premorbid functioning, stroke type and severity, vascular and systemic risk factors, and specific treatment/care-related factors. A consensus stroke measure Standard Set was developed as a simple, pragmatic method to increase the value of stroke care. The set should be validated in practice when used for monitoring and comparisons across different care settings. © 2015 The Authors.

Stroke is one of the major causes of morbidity and mortality. Its recovery and treatment depends on close clinical monitoring by a clinician especially during the first few hours after the onset of stroke. Patients who do not exhibit early motor recovery post thrombolysis may benefit from more aggressive treatment. A novel approach for monitoring stroke during the first few hours after the onset of stroke using a wireless accelerometer based motor activity monitoring system is developed. It monitors the motor activity by measuring the acceleration of the arms in three axes. In the presented proof of concept study, the measured acceleration data is transferred wirelessly using iMote2 platform to the base station that is equipped with an online algorithm capable of calculating an index equivalent to the National Institute of Health Stroke Score (NIHSS) motor index. The system is developed by collecting data from 15 patients. We have successfully demonstrated an end-to-end stroke monitoring system reporting an accuracy of calculating stroke index of more than 80%, highest Cohen's overall agreement of 0.91 (with excellent κ coefficient of 0.76). A wireless accelerometer based 'hot stroke' monitoring system is developed to monitor the motor recovery in acute-stroke patients. It has been shown to monitor stroke patients continuously, which has not been possible so far with high reliability.

Recent evidence supports that most non-lacunar cryptogenic strokes are embolic. Accordingly, these strokes have been designated as embolic strokes of undetermined source (ESUS). We undertook an international survey to characterize the frequency and clinical features of ESUS patients across global regions. Consecutive patients hospitalized for ischemic stroke were retrospectively surveyed from 19 stroke research centers in 19 different countries to collect patients meeting criteria for ESUS. Of 2144 patients with recent ischemic stroke, 351 (16%, 95% CI 15% to 18%) met ESUS criteria, similar across global regions (range 16% to 21%), and an additional 308 (14%) patients had incomplete evaluation required for ESUS diagnosis. The mean age of ESUS patients (62 years; SD = 15) was significantly lower than the 1793 non-ESUS ischemic stroke patients (68 years, p ≤ 0.001). Excluding patients with atrial fibrillation (n = 590, mean age = 75 years), the mean age of the remaining 1203 non-ESUS ischemic stroke patients was 64 years (p = 0.02 vs. ESUS patients). Among ESUS patients, hypertension, diabetes, and prior stroke were present in 64%, 25%, and 17%, respectively. Median NIHSS score was 4 (interquartile range 2-8). At discharge, 90% of ESUS patients received antiplatelet therapy and 7% received anticoagulation. This cross-sectional global sample of patients with recent ischemic stroke shows that one-sixth met criteria for ESUS, with additional ESUS patients likely among those with incomplete diagnostic investigation. ESUS patients were relatively young with mild strokes. Antiplatelet therapy was the standard antithrombotic therapy for secondary stroke prevention in all global regions. © 2016 World Stroke Organization.

The aim of this single-center prospective study was to assess the presence of Cheyne-Stokes respiration (CSR) and CSR-related variables in 68 consecutive patients with radiologically proven first-ever lacunar stroke undergoing a respiratory sleep study using a portable respiratory polygraph within the first 48 hours of stroke onset. CSR was diagnosed in 14 patients (20.6%). Patients with CSR as compared with those without CSR showed a significantly higher mean (standard deviation, SD) apnea-hypopnea index (AHI) (34.9 (21.7) versus 18.5 (14.4), P = 0.001) and central apnea index (13.1 (13.8) versus 1.8 (3.4), P = 0.0001) as well as higher scores of the Barthel index and the Canadian Neurological scale as a measure of stroke severity, and longer hospital stay. CSR was present in one of each five patients with lacunar stroke. The presence of CSR was associated with a trend towards a higher functional stroke severity and worse prognosis. PMID:23471518

Stratification of patients with transient ischemic attack (TIA) or ischemic stroke (IS) by risk of recurrent stroke can contribute to optimized secondary prevention. We therefore aimed to assess cardiovascular risk factor profiles of consecutive patients hospitalized with TIA/IS to stratify the risk of recurrent stroke according to the Essen Stroke Risk Score (ESRS) and of future cardiovascular events according to the ankle brachial index (ABI) as a marker of generalized atherosclerosis In this cross-sectional observational study, 85 neurological stroke units throughout Germany documented cardiovascular risk factor profiles of 10 consecutive TIA/IS patients on standardized questionnaires. Screening for PAD was done with Doppler ultrasonography to calculate the ABI. A total of 852 patients (57% men) with a mean age of 67+/-12.4 years were included of whom 82.9 % had IS. The median National Institutes of Health stroke sum score was 4 (TIA: 1). Arterial hypertension was reported in 71%, diabetes mellitus in 26%, clinical PAD in 10%, and an ABI < or = 0.9 in 51%. An ESRS > or = 3 was observed in 58%, which in two previous retrospective analyses corresponded to a recurrent stroke risk of > or = 4%/year. The correlation between the ESRS and the ABI was low (r = 0.21). A high proportion of patients had asymptomatic atherosclerotic disease and a considerable risk of recurrent stroke according to the ABI and ESRS category. The prognostic accuracy as well as the potential benefit of various risk stratification scores in secondary stroke prevention require validation in a larger prospective study.

Auditory stimulation increases mean blood flow velocity (MBFV) in the middle cerebral artery (MCA) in healthy individuals. Our aim was to monitor such changes in the affected MCA of patients with acute ischemic stroke (AIS). The study included 66 non-thrombolysed patients with AIS who were divided into groups according to National Institutes of Health Stroke Scale (NIHSS) score. Group I consisted of patients with NIHSS score 10 and group II with NIHSS score > or =11. Affected MCA was insonated with transcranial Doppler (TCD). MCA MBFVs were monitored during listening to music for 30 minutes. The first response of MBFV increase was measured as time (Tmax) and percentage of amplitude change (Amax). Pearson Chi-Square test was used. In 78.85% of patients there was a significant increase in MBFV compared to baseline values as a reaction to the music. There was no significant difference in Tmax or Amax between the two groups. However, a trend of longer Tmax was observed with every 2 NIHSS score increase. Music is an auditory stimulus in stroke patients and can be measured with TCD as MCA MBFV increase. Although our study showed no significant change of reaction time with the severity of stroke, a trend of prolonged Tmax was observed with NIHSS score increase.

To identify prognostic factors associated with functional outcome at 13 months in a sample of stroke rehabilitation patients. Specifically, we hypothesized that cognitive functioning early after stroke would predict long-term functional outcome independently of other factors. 163 stroke rehabilitation patients underwent a structured neuropsychological examination 2-3 weeks after hospital admittance, and their functional status was subsequently evaluated 13 months later with the modified Rankin Scale (mRS) as outcome measure. Three predictive models were built using linear regression analyses: a biological model (sociodemographics, apolipoprotein E genotype, prestroke vascular factors, lesion characteristics and neurological stroke-related impairment); a functional model (pre- and early post-stroke cognitive functioning, personal and instrumental activities of daily living, ADL, and depressive symptoms), and a combined model (including significant variables, with p value <0.05, from the biological and functional models). A combined model of 4 variables best predicted long-term functional outcome with explained variance of 49%: neurological impairment (National Institute of Health Stroke Scale; β = 0.402, p < 0.001), age (β = 0.233, p = 0.001), post-stroke cognitive functioning (Repeatable Battery of Neuropsychological Status, RBANS; β = -0.248, p = 0.001) and prestroke personal ADL (Barthel Index; β = -0.217, p = 0.002). Further linear regression analyses of which RBANS indexes and subtests best predicted long-term functional outcome showed that Coding (β = -0.484, p < 0.001) and Figure Copy (β = -0.233, p = 0.002) raw scores at baseline explained 42% of the variance in mRS scores at follow-up. Early post-stroke cognitive functioning as measured by the RBANS is a significant and independent predictor of long-term functional post-stroke outcome. Copyright © 2011 S. Karger AG, Basel.

Purpose: Radiation/chemoradiotherapy-induced carotid stenosis and cerebrovascular events in patients with nasopharyngeal carcinoma (NPC) can cause severe disability and even death. This study aimed to estimate the risk of ischemic stroke in this patient population over more than 10 years of follow-up. Methods and Materials: The study cohorts consisted of all patients hospitalized with a principal diagnosis of NPC (n = 1094), whereas patients hospitalized for an appendectomy during 1997 and 1998 (n = 4376) acted as the control group and surrogate for the general population. Cox proportional hazard model was performed as a means of comparing the stroke-free survival ratemore » between the two cohorts after adjusting for possible confounding and risk factors. Results: Of the 292 patients with ischemic strokes, 62 (5.7%) were from the NPC cohort and 230 (5.3%) were from the control group. NPC patients ages 35-54 had a 1.66 times (95% CI, 1.16-2.86; p = 0.009) higher risk of ischemic stroke after adjusting for patient characteristics, comorbidities, geographic region, urbanization level of residence, and socioeconomic status. There was no statistical difference in ischemic stroke risk between the NPC patients and appendectomy patients ages 55-64 years (hazard ratio = 0.87; 95% CI, 0.56-1.33; p = 0.524) after adjusting for other factors. Conclusions: Young NPC patients carry a higher risk for ischemic stroke than the general population. Besides regular examinations of carotid duplex, different irradiation strategies or using new technique of radiotherapy, such as intensity modulated radiation therapy or volumetric modulated arc therapy, should be considered in young NPC patients.« less

Background: Although anterior cruciate ligament (ACL) reconstruction is generally regarded as a successful procedure, only 65% of patients return to their preinjury sport. While return-to-sport rates are likely higher in younger patients, there is a paucity of data that focus on the younger patient and their return-to-sport experience after ACL reconstruction. Purpose: To investigate a range of return-to-sport outcomes in younger athletes who had undergone ACL reconstruction surgery. Study Design: Case series; Level of evidence, 4. Methods: A group of 140 young patients (<20 years old at surgery) who had 1 ACL reconstruction and no subsequent ACL injuries completed a survey regarding details of their sport participation at a mean follow-up of 5 years (range, 3-7 years). Results: Overall, 76% (95% CI, 69%-83%) of the young patient group returned to the same preinjury sport. Return rates were higher for males than females (81% vs 71%, respectively; P > .05). Of those who returned to their sport, 65% reported that they could perform as well as before the ACL injury and 66% were still currently participating in their respective sport. Young athletes who never returned to sport cited fear of a new injury (37%) or study/work commitments (30%) as the primary reasons for dropout. For those who had successfully returned to their preinjury sport but subsequently stopped participating, the most common reason cited for stopping was study/work commitments (53%). At a mean 5-year follow-up, 48% of female patients were still participating in level I (jumping, hard pivoting) sports, as were 54% of males. Conclusion: A high percentage of younger patients return to their preinjury sport after ACL reconstruction surgery. For patients in this cohort who had not sustained a second ACL injury, the majority continue to participate and are satisfied with their performance. PMID:28473996

Patients with stroke had higher incidence of falls and hip fractures. However, the risk of traumatic brain injury (TBI) and post-TBI mortality in patients with stroke was not well defined. Our study is to investigate the risk of TBI and post-TBI mortality in patients with stroke. Using reimbursement claims from Taiwan's National Health Insurance Research Database, we conducted a retrospective cohort study of 7622 patients with stroke and 30 488 participants without stroke aged 20 years and older as reference group. Data were collected on newly developed TBI after stroke with 5 to 8 years' follow-up during 2000 to 2008. Another nested cohort study including 7034 hospitalized patients with TBI was also conducted to analyze the contribution of stroke to post-TBI in-hospital mortality. Compared with the nonstroke cohort, the adjusted hazard ratio of TBI risk among patients with stroke was 2.80 (95% confidence interval = 2.58-3.04) during the follow-up period. Patients with stroke had higher mortality after TBI than those without stroke (10.2% vs 3.2%, P < .0001) with an adjusted relative risk (RR) of 1.46 (95% confidence interval = 1.15-1.84). Recurrent stroke (RR = 1.60), hemorrhagic stroke (RR = 1.68), high medical expenditure for stroke (RR = 1.80), epilepsy (RR = 1.79), neurosurgery (RR = 1.94), and hip fracture (RR = 2.11) were all associated with significantly higher post-TBI mortality among patients with stroke. Patients with stroke have an increased risk of TBI and in-hospital mortality after TBI. Various characteristics of stroke severity were all associated with higher post-TBI mortality. Special attention is needed to prevent TBI among these populations.

The effectiveness of comprehensive stroke center (CSC) capabilities on stroke mortality remains uncertain. We performed a nationwide study to examine whether CSC capabilities influenced in-hospital mortality of patients with ischemic and hemorrhagic stroke. Of the 1,369 certified training institutions in Japan, 749 hospitals responded to a questionnaire survey regarding CSC capabilities that queried the availability of personnel, diagnostic techniques, specific expertise, infrastructure, and educational components recommended for CSCs. Among the institutions that responded, data on patients hospitalized for stroke between April 1, 2010 and March 31, 2011 were obtained from the Japanese Diagnosis Procedure Combination database. In-hospital mortality was analyzed using hierarchical logistic regression analysis adjusted for age, sex, level of consciousness on admission, comorbidities, and the number of fulfilled CSC items in each component and in total. Data from 265 institutions and 53,170 emergency-hospitalized patients were analyzed. Mortality rates were 7.8% for patients with ischemic stroke, 16.8% for patients with intracerebral hemorrhage (ICH), and 28.1% for patients with subarachnoid hemorrhage (SAH). Mortality adjusted for age, sex, and level of consciousness was significantly correlated with personnel, infrastructural, educational, and total CSC scores in patients with ischemic stroke. Mortality was significantly correlated with diagnostic, educational, and total CSC scores in patients with ICH and with specific expertise, infrastructural, educational, and total CSC scores in patients with SAH. CSC capabilities were associated with reduced in-hospital mortality rates, and relevant aspects of care were found to be dependent on stroke type.

The present study aims at elucidating the impact of stroke on psychosocial functioning of stroke survivors. Data were investigated using interpretative thematic analysis of illness stories produced by 29 patients. Eight themes emerged from the data: Medical Information; Interpersonal Changes; Cognitive, Physical and Emotional Functioning; Strategies of Coping; Social Support; and Information Irrelevant to the Question. The most frequent organization of the themes followed the course of medical intervention and rehabilitation. Narrations of individual patients varied in terms of the presence of particular themes, the amount of information on each topic and organization. The results suggest that the analysis of non-guided illness narratives can be effectively used to identify the thematic areas important to individual stroke patients. The thematic content analysis of stroke stories can allow health professionals to better understand the patient's state of knowledge related to illness as well as his or her socio-psychological functioning which may be useful in the course of planning further assessment and rehabilitation of patients with stroke. Implications for Rehabilitation Experience of illness and life changes following stroke should be recognized as central to the provision of targeted rehabilitation. To understand the subjective perspective a content analysis of the content narrative is recommended. Our study highlights seven general thematic categories that may be regarded as key. The categories may be useful for clinicians to help individuals to clarify their main concerns following a stroke.

Decompressive hemicraniectomy (DHC) after space-occupying strokes among patients older than 60 years has been shown to reduce mortality rates but at the cost of severe disability. There is an ongoing debate about what could be considered an acceptable outcome for these patients. Data about retrospective consent to the procedure after lengthy time periods are lacking. This study included 79 consecutive patients who underwent DHC during a 7.75-year period. Surviving patients were assessed for functional and psychological outcome, quality of life (QoL) and retrospective consent for the procedure. Patients younger than 60 years were compared with older patients. Of our 79 patients, 44 were younger than 60 years (median 50 years, interquartile range (IQR) 19-59 years) and 35 were older (median 68 years, interquartile range 60-87 years). The 30-day mortality rate was higher for the older group, but the difference was not statistically significant. Functional outcome was significantly better in the younger group: 31% of the patients in this group vs. 10% in the older group had a modified Rankin Scale score of 0-3 (p = 0.046). The mean National Institutes of Health Stroke Scale score was 17 ± 14 for the younger group and 29 ± 15 for the older group (p = 0.002). On the 36-Item Short Form Health Survey, with the exception of the item 'General health', the older group reported higher values for all items, with statistically significant differences between the 2 groups on the items 'Role limitation emotional' (p = 0.0007) and 'Vitality' (p = 0.02). In the younger group, 29% of patients retrospectively declined consent for DHC opposed to 0% of patients in the older group (p = 0.07). Despite impaired functional outcome after DHC, indicators of QoL and retrospective consent are higher for patients older than 60 years over the long term. This finding should be taken into account by those who counsel patients and caregivers with regard to this serious procedure. © 2015 S. Karger

In the United States, approximately 550,000 new cases of stroke are reported annually, resulting in 150,000 deaths and leaving 300,000 survivors disabled. Thromboembolic strokes account for an estimated 300,000-400,000 of the 550,000 reported new cases of stroke each year. These thromboembolic strokes may be treatable by thrombolytic therapy which involves injecting a thrombolytic agent directly into the thrombus. As the clot dissolves, it breaks into fragments. One particular diagnostic fragment is the D dimer fragment which has antigenic properties. At LLNL, the authors are developing various catheter-based microtools to treat stroke. As part of the package, fiber optic pH sensorsmore » and D dimer biosensors are being developed for novel applications, in that they will be coaxially threaded through a catheter to the damaged area of the brain. The pH sensor would allow local measurements of tissue viability, providing an assessment on the patient`s status and indicating the optimal treatment plan. The D dimer biosensor would allow local measurements of the products of thrombolysis, i.e., D dimer, assisting in the identification of clot type and providing feedback on the dosage and infusion rate of the thrombocytic agent.« less

Purpose The purpose of this study was to analyze the status of inpatient care for acute first-ever stroke at three general hospitals in Korea to provide basic data and useful information on the development of comprehensive and systematic rehabilitation care for stroke patients. Materials and Methods This study conducted a retrospective complete enumeration survey of all acute first-ever stroke patients admitted to three distinct general hospitals for 2 years by reviewing medical records. Both ischemic and hemorrhagic strokes were included. Survey items included demographic data, risk factors, stroke type, state of rehabilitation treatment, discharge destination, and functional status at discharge. Results A total of 2159 patients were reviewed. The mean age was 61.5±14.4 years and the ratio of males to females was 1.23:1. Proportion of ischemic stroke comprised 54.9% and hemorrhagic stroke 45.1%. Early hospital mortality rate was 8.1%. Among these patients, 27.9% received rehabilitation consultation and 22.9% underwent inpatient rehabilitation treatment. The mean period from admission to rehabilitation consultation was 14.5 days. Only 12.9% of patients were transferred to a rehabilitation department and the mean period from onset to transfer was 23.4 days. Improvements in functional status were observed in the patients who had received inpatient rehabilitation treatment after acute stroke management. Conclusion Our analysis revealed that a relatively small portion of patients who suffered from an acute first-ever stroke received rehabilitation consultation and inpatient rehabilitation treatment. Thus, applying standardized clinical practice guidelines for post-acute rehabilitation care is needed to provide more effective and efficient rehabilitation services to patients with stroke.

2013-01-01

Background Vertebral artery origin (VAO) stenosis is occasionally observed in patients who have acute ischemic stroke. We investigated the long-term outcomes and clinical significance of VAO stenosis in patients with acute ischemic stroke. Methods We performed a prospective observational study using a single stroke center registry to investigate the risk of recurrent stroke and vascular outcomes in patients with acute ischemic stroke and VAO stenosis. To relate the clinical significance of VAO stenosis to the vascular territory of the index stroke, patients were classified into an asymptomatic VAO stenosis group and a symptomatic VAO stenosis group. Results Of the 774 patients who had acute ischemic stroke, 149 (19.3%) of them had more than 50% stenosis of the VAO. During 309 patient-years of follow-up (mean, 2.3 years), there were 7 ischemic strokes, 6 hemorrhagic strokes, and 2 unknown strokes. The annual event rates were 0.97% for posterior circulation ischemic stroke, 4.86% for all stroke, and 6.80% for the composite cardiovascular outcome. The annual event rate for ischemic stroke in the posterior circulation was significantly higher in patients who had symptomatic VAO stenosis than in patients who had asymptomatic stenosis (1.88% vs. 0%, p = 0.046). In a multivariate analysis, the hazard ratio, per one point increase of the Essen Stroke Risk Score (ESRS) for the composite cardiovascular outcome, was 1.46 (95% CI, 1.02-2.08, p = 0.036). Conclusions Long-term outcomes of more than 50% stenosis of the VAO in patients with acute ischemic stroke were generally favorable. Additionally, ESRS was a predictor for the composite cardiovascular outcome. Asymptomatic VAO stenosis may not be a specific risk factor for recurrent ischemic stroke in the posterior circulation. However, VAO stenosis may require more clinical attention as a potential source of recurrent stroke when VAO stenosis is observed in patients who have concurrent ischemic stroke in the posterior

Stroke is a leading cause of disability and a major public health problem. To determine frequency and degree of post-stroke depression (PSD) and its impact on functioning in young and adult stroke patients in a rehabilitation unit. The study included 72 stroke patients (aged 29-59 years) who were attending rehabilitation. The patients were assessed for depressive symptoms by Beck Depression Inventory (BDI), and their functioning by using the Stroke Impact Scale (SIS) and the Barthel Index of Activities of Daily Living (ADL). Forty-eight patients had different degrees of depression: borderline clinical depression (13.8%), moderate depression (34.7%), severe depression (15.2%) or extreme depression (2.9%). There were no significant differences of BDI scores in 30-39, 40-49 and 50-59 years groups. Statistically significant correlations were between BDI score and SIS score, between BDI score and ADL index, and between SIS score and ADL index in men, women and total study patients. More than half of the PSD patients had a moderate degree of depression. Significant correlations were noticed between depressive symptoms and functional status evaluated both by an instrument of assessing stroke impact upon general health and an instrument for assessing the everyday activities.

Endovascular treatment (EVT) is a new standard of care for selected, large vessel occlusive strokes. We aimed to determine frequency of potentially eligible patients for intravenous thrombolysis (IVT) and EVT in comprehensive stroke centers. In addition, predictors of EVT eligibility were derived. Patients from a stroke center-based registry (2003-2014), admitted within 24 hours of last proof of usual health, were selected if they had all data to determine IVT and EVT eligibility according to American Heart Association/American Stroke Association (AHA/ASA) guidelines (class I-IIa recommendations). Moreover, less restrictive criteria adapted from randomized controlled trials and clinical practice were tested. Maximum onset-to-door time windows for IVT eligibility were 3.5 hours (allowing door-to-needle delay of ≤60 minutes) and 4.5 hours for EVT eligibility (door-to-groin delay ≤90 minutes). Demographic and clinical information were used in logistic regression analysis to derive variables associated with EVT eligibility. A total of 2704 patients with acute ischemic stroke were included, of which 26.8% were transfers. Of all patients with stroke arriving at our comprehensive stroke center, a total proportion of 12.4% patients was eligible for IVT. Frequency of EVT eligibility differed between AHA/ASA guidelines and less restrictive approach: 2.9% versus 4.9%, respectively, of all patients with acute ischemic stroke and 10.5% versus 17.7%, respectively, of all patients arriving within <6 hours. Predictors for AHA-EVT eligibility were younger, shorter onset-to-admission delays, higher National Institutes of Health Stroke Scale (NIHSS), decreased vigilance, hemineglect, absent cerebellar signs, atrial fibrillation, smoking, and decreasing glucose levels (area under the curve=0.86). Of patients arriving within 6 hours at a comprehensive stroke center, 10.5% are EVT eligible according to AHA/ASA criteria, 17.7% according to criteria resembling randomized controlled

Motor recovery monitoring using acceleration measurements in post acute stroke patients

PubMed Central

2013-01-01

Background Stroke is one of the major causes of morbidity and mortality. Its recovery and treatment depends on close clinical monitoring by a clinician especially during the first few hours after the onset of stroke. Patients who do not exhibit early motor recovery post thrombolysis may benefit from more aggressive treatment. Method A novel approach for monitoring stroke during the first few hours after the onset of stroke using a wireless accelerometer based motor activity monitoring system is developed. It monitors the motor activity by measuring the acceleration of the arms in three axes. In the presented proof of concept study, the measured acceleration data is transferred wirelessly using iMote2 platform to the base station that is equipped with an online algorithm capable of calculating an index equivalent to the National Institute of Health Stroke Score (NIHSS) motor index. The system is developed by collecting data from 15 patients. Results We have successfully demonstrated an end-to-end stroke monitoring system reporting an accuracy of calculating stroke index of more than 80%, highest Cohen’s overall agreement of 0.91 (with excellent κ coefficient of 0.76). Conclusion A wireless accelerometer based ‘hot stroke’ monitoring system is developed to monitor the motor recovery in acute-stroke patients. It has been shown to monitor stroke patients continuously, which has not been possible so far with high reliability. PMID:23590690

Background and Purpose— Anxiety after stroke is common and disabling. Stroke trialists have treated anxiety as a homogenous condition, and intervention studies have followed suit, neglecting the different treatment approaches for phobic and generalized anxiety. Using diagnostic psychiatric interviews, we aimed to report the frequency of phobic and generalized anxiety, phobic avoidance, predictors of anxiety, and patient outcomes at 3 months poststroke/transient ischemic attack. Methods— We followed prospectively a cohort of new diagnosis of stroke/transient ischemic attack at 3 months with a telephone semistructured psychiatric interview, Fear Questionnaire, modified Rankin Scale, EuroQol-5D5L, and Work and Social Adjustment Scale. Results— Anxiety disorder was common (any anxiety disorder, 38 of 175 [22%]). Phobic disorder was the predominant anxiety subtype: phobic disorder only, 18 of 175 (10%); phobic and generalized anxiety disorder, 13 of 175 (7%); and generalized anxiety disorder only, 7 of 175 (4%). Participants with anxiety disorder reported higher level of phobic avoidance across all situations on the Fear Questionnaire. Younger age (per decade increase in odds ratio, 0.64; 95% confidence interval, 0.45–0.91) and having previous anxiety/depression (odds ratio, 4.38; 95% confidence interval, 1.94–9.89) were predictors for anxiety poststroke/transient ischemic attack. Participants with anxiety disorder were more dependent (modified Rankin Scale score 3–5, [anxiety] 55% versus [no anxiety] 29%; P<0.0005), had poorer quality of life on EQ-5D5L, and restricted participation (Work and Social Adjustment Scale: median, interquartile range, [anxiety] 19.5, 10–27 versus [no anxiety] 0, 0–5; P<0.001). Conclusions— Anxiety after stroke/transient ischemic attack is predominantly phobic and is associated with poorer patient outcomes. Trials of anxiety intervention in stroke should consider the different treatment approaches needed for phobic and

Oral anticoagulation in elderly patients as secondary prevention of cardioembolic strokes

PubMed Central

2010-01-01

Background Stroke incidence increases with age. Atrial fibrillation (AF) is an important risk factor for ischemic stroke and its incidence also increases with age. However oral anticoagulant therapy (OAT) tends to be underused in the elderly population. Methods Elderly patients (> = 80 years) with an ischemic stroke admitted in our department between 1/7/2003 and 31/6/2005 were prospectively evaluated. Baseline characteristics, risk factors, treatment and etiology according to TOAST criteria were recorded. Patients treated with OAT were followed up in order to assess any side effect and stroke recurrence. Mean follow-up was of 19.5 months (7-45) from discharge. Results Sixty four out of a hundred and fifty nine elderly patients (40.25%) were classified as cardioembolic; mean age was 84.5 years (80-97) and 64.6% were women. AF had been previously identified in 60% of them (16.9% were on OAT and 40.6% on antiplatelet therapy). At discharge, 32 patients (49.2%) were on OAT. In the follow-up 4 patients (12.5%) suffered systemic haemorrhages (3 urinary, 1 gastrointestinal bleeding), with no change in their functional status. Mean INR in this group was 5.9 [3-11] and, in 3 of them, OAT was cancelled. No brain haemorrhages were recorded. Ischemic stroke recurred in 4 patients (INR < 1.8 in 3 of them; the other, INR 2.35). Three patients had died at the end of the follow-up, one of them as a consequence of ischemic stroke recurrence. Discussion Twenty eight point eight of stroke patients admitted in the period of study were >80 years. The high proportion of cardioembolic strokes in this age segment contrasts with the general underuse of OAT as antithrombotic prophylaxis. Our study suggests that OAT is a safe strategy when carefully prescribed, even for elderly patients. PMID:20525389

The Importance of Patient Involvement in Stroke Rehabilitation

2016-01-01

Objective To investigate the perceived needs for health services by persons with stroke within the first year after rehabilitation, and associations between perceived impact of stroke, involvement in decisions regarding care/treatment, and having health services needs met. Method Data was collected, through a mail survey, from patients with stroke who were admitted to a university hospital in 2012 and had received rehabilitation after discharge from the stroke unit. The rehabilitation lasted an average of 2 to 4.6 months. The Stroke Survivor Needs Survey Questionnaire was used to assess the participants' perceptions of involvement in decisions on care or treatment and needs for health services in 11 problem areas: mobility, falls, incontinence, pain, fatigue, emotion, concentration, memory, speaking, reading, and sight. The perceived impact of stroke in eight areas was assessed using the Stroke Impact Scale (SIS) 3.0. Eleven logistic regression models were created to explore associations between having health services needs met in each problem area respectively (dependent variable) and the independent variables. In all models the independent variables were: age, sex, SIS domain corresponding to the dependent variable, or stroke severity in cases when no corresponding SIS domain was identified, and involvement in decisions on care and treatment. Results The 63 participants who returned the questionnaires had a mean age of 72 years, 33 were male and 30 were female. Eighty percent had suffered a mild stroke. The number of participants who reported problems varied between 51 (80%, mobility) and 24 (38%, sight). Involvement in decisions on care and treatment was found to be associated with having health services needs met in six problem areas: falls, fatigue, emotion, memory, speaking, and reading. Conclusions The results highlight the importance of involving patients in making decisions on stroke rehabilitation, as it appears to be associated with meeting their health

Prior studies suggest differences in stroke care associated with race/ethnicity. We sought to determine whether such differences existed in a population of black, Hispanic, and white patients hospitalized with stroke among hospitals participating in a quality-improvement program. We analyzed in-hospital mortality and 7 stroke performance measures among 397,257 patients admitted with ischemic stroke to 1181 hospitals participating in the Get With The Guidelines-Stroke program 2003 through 2008. Relative to white patients, black and Hispanic patients were younger and more often had diabetes mellitus and hypertension. After adjustment for both patient- and hospital-level variables, black patients had lower odds relative to white patients of receiving intravenous thrombolysis (odds ratio [OR], 0.84; 95% confidence interval [CI], 0.77 to 0.91), deep vein thrombosis prophylaxis (OR, 0.88; 95% CI, 0.83 to 0.92), smoking cessation (OR, 0.85; 95% CI, 0.79 to 0.91), discharge antithrombotics (OR, 0.88; 95% CI, 0.84 to 0.92), anticoagulants for atrial fibrillation (OR, 0.84; 95% CI, 0.75 to 0.94), and lipid therapy (OR, 0.91; 95% CI, 0.88 to 0.96), and of dying in-hospital (OR, 0.90; 95% CI, 0.85 to 0.95). Hispanic patients received similar care as their white counterparts on all 7 measures and had similar in-hospital mortality. Black (OR, 1.31; 95% CI, 1.28 to 1.35) and Hispanic (OR, 1.16; 95% CI, 1.11 to 1.20) patients had higher odds of exceeding the median length of hospital stay relative to whites. During the study, quality of care improved in all 3 race/ethnicity groups. Black patients with stroke received fewer evidence-based care processes than Hispanic or white patients. These differences could lead to increased risk of recurrent stroke. Quality of care improved substantially in the Get With The Guidelines-Stroke Program over time for all 3 racial/ethnic groups.

With the advent of time-dependent thrombolytic therapy for ischemic stroke, it has become increasingly important to differentiate transient ischemic attack (TIA) from minor stroke patients after symptom onset quickly. This study investigated the difference between TIA and minor stroke based on age, blood pressure, clinical features, duration of TIA, presence of diabetes, ABCD² score, digital subtraction angiography (DSA) and blood lipids. One hundred seventy-one patients with clinical manifestations as transient neurological deficits in Nanjing Drum Tower Hospital were studied retrospectively. All patients were evaluated by ABCD² score, blood lipid test, fibrinogen, and Holter electrocardiograph and DSA on admission. Patients were categorized into TIA group or minor stroke group according to CT and MRI scan 24 h within symptom onset. The study suggested that minor stroke patients were more likely to have a higher ABCD² score (odds ratio (OR) 2.060; 95% confidence interval (CI) 1.293-3.264). Receiver-operating characteristic curves identified ABCD² score >4 as the optimal cut-off for minor stroke diagnosis. Total serum cholesterol seemed a better diagnostic indicator to discriminate minor stroke from TIA (OR 4.815; 95% CI 0.946-1.654) than other blood lipids in simple logistic regression, but not valuable for the differentiation between TIA and minor stroke in multivariate logistic regression. Higher severity of intracranial internal carotid stenosis, especially >90%, were more likely to have minor stroke, but was not a reliable diagnostic indicator (P > 0.05). ABCD² could help clinicians to differentiate possible TIA from minor stroke at hospital admission while blood lipid parameters and artery stenosis location offer limited help.

Stroke is a leading cause of death and disability in most developed countries and developing nations. Majority of the stroke survivors are left with significant physical and cognitive impairments. In addition to the improved acute stroke care, they often benefit from rehabilitation in improving their function. This was the first study done to document function for post stroke patients in Malaysia. It was prospective study conducted to document functional status of acute stroke patients upon admission, discharge and at 3 months post stroke. Assessment of functional status for these patients are based on their activities of daily living and ambulation i.e. self-care, sphincter control, mobility, locomotion, communication and social cognition. It is also aimed to describe their demographic and clinical characteristics. Correlation of functional status at 3 months post stroke with the initial severity of stroke was also explored. A total of fifty-one patients with acute stroke in University Malaya Medical Centre (UMMC) were recruited. The patient's age ranged from 38 to 83 years with a mean of 60.2 years. Thirty-six patients (71%) were first stroke sufferers and fifteen patients (29%) had recurrent stroke. At discharge from acute stay, 13% of patients were able to ambulate with aids and 87% needed assistance for ambulation in varying degrees. Eighty-two percent of patients showed improvement in overall function (both motor and cognition) at 3 months post stroke. Sixty percent of patients were independent in ambulation and 40% required assistance. Significant correlation was seen between the initial severity of stroke and functional status at 3 months post stroke. Functional status of patients with stroke has improved at 3 months post stroke. A comprehensive rehabilitation medicine programme should be incorporated into management of stroke patients to expedite functional recovery and improve patient's independence.

Acute stroke patients can be transferred directly to a Comprehensive Stroke Center (CSC), where acute stroke expertise is provided 24 h a day, seven days a week, and thrombolytic treatment is administered; or they may initially receive attention at an unspecialized community hospital with secondary transfer to the CSC. Our aim is to analyze the influence of previous attention at unspecialized community hospitals on the outcome of ischemic stroke patients treated with thrombolysis. We studied 153 consecutive ischemic stroke patients treated with t-PA over a 30-month period. The primary outcome variable was functional independence at 90 days (Rankin scale, mRS patients (29.5%) received initial attention at community hospitals with secondary transfer to the CSC. Median time from onset to t-PA administration was shorter in patients with direct access to the CSC (135 vs. 165 min; p < 0.001) and stroke severity was higher (NIHSS 12 vs. 9; p = 0.017). Patients who received initial attention at the CSC had a higher frequency of neurologic improvement (59.3% vs. 37.2%; p = 0.014) and a lower rate of symptomatic hemorrhage (4.7% vs. 14%; p = 0.04). Compared to initial attention at an unspecialized hospital, direct admission to the CSC was associated with an odds ratio of 2.48 (95% CI, 1.04-5.88; p = 0.039) for good outcome after adjustment for stroke severity at baseline and other potential confounders. Direct access to a CSC is associated with shorter onset-to-treatment time and better outcome for ischemic stroke patients treated with thrombolysis in comparison with initial attention at an unspecialized hospital with secondary transfer.

OBJECTIVES—To clarify whether different causative events (trauma, stroke, intracranial surgery), time of intervention, and treatment mode influence outcome, patients with fixed and dilated pupils (FDPs) in a prospective neurosurgical series were evaluated.
METHODS—Ninety nine consecutive patients who presented with or developed one or two FDPs, were split into three groups according to the respective aetiology: 46 patients had a trauma, 41 patients a stroke (subarachnoid or intracerebral haemorrhage), and 12 patients had undergone previous elective intracranial surgery. Appropriate therapy was performed depending on the CT findings. Outcome was classified according to the Glasgow outcome scale (GOS).
RESULTS—Overall mortality was 75%. In 15% outcome was unfavourable (GOS 2 and 3), and in 10% favourable (GOS 4, 5) at 24 month follow up. No differences in outcome were found between trauma, stroke, and postelective surgery groups. Unilaterally FDP was associated with a better chance of survival (46% v 13%; p<0.01). Age did not correlate with survival, but younger survivors had a significantly better outcome. Patients in whom an intracranial mass was removed surgically had a 42% survival rate, compared with 8% with conservative treatment (p<0.01). Patients with a shorter delay from FDPs to intervention had a better chance of recovery after trauma and previous intracranial surgery (p<0.05). No patient survived better than a vegetative state, if previous FDPs did not become reactive shortly after therapy. If both pupils became reactive on therapy, the chance of survival was 62%. Of these survivors 42% had a favourable outcome.
CONCLUSION—Bilateral restoration of pupillary reactivity shortly after therapy is crucial for survival. Surgical evacuation of an intracranial mass, unilateral FDPs, early intervention, and younger age are related to better chances of survival or recovery. The prognosis of patients with FDPs after trauma, stroke, and previous elective

Background The effectiveness of comprehensive stroke center (CSC) capabilities on stroke mortality remains uncertain. We performed a nationwide study to examine whether CSC capabilities influenced in-hospital mortality of patients with ischemic and hemorrhagic stroke. Methods and Results Of the 1,369 certified training institutions in Japan, 749 hospitals responded to a questionnaire survey regarding CSC capabilities that queried the availability of personnel, diagnostic techniques, specific expertise, infrastructure, and educational components recommended for CSCs. Among the institutions that responded, data on patients hospitalized for stroke between April 1, 2010 and March 31, 2011 were obtained from the Japanese Diagnosis Procedure Combination database. In-hospital mortality was analyzed using hierarchical logistic regression analysis adjusted for age, sex, level of consciousness on admission, comorbidities, and the number of fulfilled CSC items in each component and in total. Data from 265 institutions and 53,170 emergency-hospitalized patients were analyzed. Mortality rates were 7.8% for patients with ischemic stroke, 16.8% for patients with intracerebral hemorrhage (ICH), and 28.1% for patients with subarachnoid hemorrhage (SAH). Mortality adjusted for age, sex, and level of consciousness was significantly correlated with personnel, infrastructural, educational, and total CSC scores in patients with ischemic stroke. Mortality was significantly correlated with diagnostic, educational, and total CSC scores in patients with ICH and with specific expertise, infrastructural, educational, and total CSC scores in patients with SAH. Conclusions CSC capabilities were associated with reduced in-hospital mortality rates, and relevant aspects of care were found to be dependent on stroke type. PMID:24828409

Suicide rates in Korea have increased dramatically. Stroke is considered one of the most debilitating neurological disorders, resulting in physical impairment, disability, and death. The present study attempted to examine factors related to suicidal ideation in community-dwelling stroke patients. The Korea Welfare Panel Study was used to investigate the relationship between demographic and psychological variables and suicidal ideation among these individuals. Depression was assessed using the Center for Epidemiological Studies Depression Scale 11 (CES-D-11). Self-esteem was assessed using Rosenberg's Self-Esteem Scale. The prevalence of suicidal thought among stroke patients was estimated at 13.99%. Multiple logistic regression analysis indicated that both older age and depression were significant independent risk factors for suicidal ideation. High-priority health care plans can prevent suicide in stroke patients suffering from depression. Assessing risk for suicide and monitoring the high-risk group is integral to health care. Stroke patients with depression, particularly older patients, would be prime targets for suicide intervention programs.

Background Little is known about the association between age and readmission within 30 days after hospitalization for acute ischemic stroke. Aim To examine the age-related differences in rate and principal reason of 30-day readmissions in patients hospitalized for acute ischemic stroke. Methods In this retrospective, population-based cohort study using State Inpatient Databases from eight US states, we identified all adults hospitalized for acute ischemic stroke. We grouped the patients into four age categories: < 65, 65-74, 75-84, and ≥85 years. Outcomes were any-cause readmission within 30 days of discharge from the index hospitalization for acute ischemic stroke and the principal diagnosis of 30-day readmission. Results We identified 620,788 hospitalizations for acute ischemic stroke. The overall 30-day readmission rate was 16.6% with an increase with advanced age. Compared to patients aged <65 years, the readmission rate was significantly higher in age 65-74 years (OR 1.19; 95% CI 1.16-1.21), in age 75-84 years (OR 1.29; 95% CI 1.27-1.31), and in ≥ 85 years (OR 1.24; 95% CI 1.22-1.27; all P<0.001). There was heterogeneity in the age-readmission rate association between men and women (P interaction  < 0.001). Overall, 45.8% of readmissions were assigned stroke-related conditions or rehabilitation care. Compared to younger adults, older adults were more likely to present with non-stroke-related conditions (46.1% in < 65 years, 50.6% in 65-74 years, 57.1% in 75-84 years, and 62.9% in ≥ 85 years; P<0.001). Conclusions Advanced age was associated with a higher 30-day readmission rate after acute ischemic stroke. Compared with younger adults, older adults were more likely to be readmitted for non-stroke-related conditions.

Limited information is available on stroke prevention in high-risk patients with preexisting cardiovascular disease. Our aim was to use admission low-density lipoprotein (LDL) values to evaluate differences in the attainment of National Cholesterol Education Program-Adult Treatment Panel III guidelines goals at the time of the index event in high-risk patients with stroke and preexisting cardio- or cerebrovascular disease. Observational study, using data from the Get-With-The-Guidelines-Stroke Registry including 913 436 patients with an acute ischemic stroke or transient ischemic attack from April 2003 to September 2012. Participants were classified as high risk if they had history of transient ischemic attack (TIA), stroke (cardiovascular disease), and coronary artery disease (CAD). Of the 913 436 patients admitted with an acute stroke or TIA, 194 557 (21.3%) had previous stroke/TIA, 148 833 (16.3%) had previous CAD, and 88 605 (9.7%) had concomitant CAD and cardiovascular disease. Overall, only 68% of patients with stroke were at their preadmission National Cholesterol Education Program III guideline-recommended LDL target; 51.3% had LDL <100 mg/dL; and only 19.8% had LDL<70 mg/dL. Among those presenting with a recurrent stroke, >45% had LDL>100 mg/dL. When compared with patients with CAD, patients with previous TIA/stroke were less likely to have LDL<100 or <70 mg/dL. In multivariable analysis, older age, men, white race, lack of major vascular risk factors, previous use of cholesterol-lowering therapy, and care provided in larger hospitals were associated with meeting LDL targets on admission testing. Management of dyslipidemia in high-risk patients with preexistent CAD or stroke continues to be suboptimal. Only 1 in 5 patients with prior TIA/stroke had LDL levels <70 mg/dL. © 2014 American Heart Association, Inc.

Clinical trial planning and site selection require an accurate estimate of the number of eligible patients at each site. In this study, we developed a tool to calculate the proportion of patients who would meet a specific trial's age, baseline severity, and time to treatment inclusion criteria. From a sample of 1322 consecutive patients with acute ischemic cerebrovascular syndromes, we developed regression curves relating the proportion of patients within each range of the 3 variables. We used half the patients to develop the model and the other half to validate it by comparing predicted vs actual proportions who met the criteria for 4 current stroke trials. The predicted proportion of patients meeting inclusion criteria ranged from 6% to 28% among the different trials. The proportion of trial-eligible patients predicted from the first half of the data were within 0.4% to 1.4% of the actual proportion of eligible patients. This proportion increased logarithmically with National Institutes of Health Stroke Scale score and time from onset; lowering the baseline limits of the National Institutes of Health Stroke Scale score and extending the treatment window would have the greatest impact on the proportion of patients eligible for a stroke trial. This model helps estimate the proportion of stroke patients eligible for a study based on different upper and lower limits for age, stroke severity, and time to treatment, and it may be a useful tool in clinical trial planning.

Increased aortic stiffness (measured by carotid-femoral pulse wave velocity) and central augmentation index have been shown to independently predict cardiovascular events, including stroke. We studied whether pulse wave velocity and central augmentation index predict functional outcome after ischemic stroke. In a prospective study, we enrolled 99 patients with acute ischemic stroke (age 63.7 ± 12.4 years, admission National Institutes of Health Stroke Scale score 6.6 ± 6.6, mean ± SD). Carotid-femoral pulse wave velocity and central augmentation index (SphygmoCor) were measured 1 week after stroke onset. Functional outcome was evaluated 90 days after stroke using the modified Rankin Scale with modified Rankin Scale score of 0 to 1 considered an excellent outcome. In univariate analysis, low carotid-femoral pulse wave velocity (P=0.000001) and low central augmentation index (P=0.028) were significantly associated with excellent stroke outcome. Age, severity of stroke, presence of previous stroke, diabetes, heart rate, and peripheral pressures also predicted stroke functional outcome. In multivariate analysis, the predictive value of carotid-femoral pulse wave velocity (<9.4 m/s) remained significant (OR, 0.21; 95% CI, 0.06-0.79; P=0.02) after adjustment for age, National Institutes of Health Stroke Scale score on admission, and presence of previous stroke. By contrast, central augmentation index had no significant predictive value after adjustment. This study indicates that aortic stiffness is an independent predictor of functional outcome in patients with acute ischemic stroke.

Among participants in the Secondary Prevention of Small Subcortical Strokes randomized trial, we sought to identify patients with high versus low rates of recurrent ischemic stroke and to assess effects of aggressive blood pressure control and dual antiplatelet therapy according to risk status. Multivariable analyses of 3020 participants with recent magnetic resonance imaging-defined lacunar strokes followed for a mean of 3.7 years with 243 recurrent ischemic strokes. Prior symptomatic lacunar stroke or transient ischemic attack (TIA) (hazard ratio [HR] 2.2, 95% confidence interval [CI] 1.6, 2.9), diabetes (HR 2.0, 95% CI 1.5, 2.5), black race (HR 1.7, 95% CI 1.3, 2.3), and male sex (HR 1.5, 95% CI 1.1, 1.9) were each independently predictive of recurrent ischemic stroke. Recurrent ischemic stroke occurred at a rate of 4.3% per year (95% CI 3.4, 5.5) in patients with prior symptomatic lacunar stroke or TIA (15% of the cohort), 3.1% per year (95% CI 2.6, 3.9) in those with more than 1 of the other 3 risk factors (27% of the cohort), and 1.3% per year (95% CI 1.0, 1.7) in those with 0-1 risk factors (58% of the cohort). There were no significant interactions between treatment effects and stroke risk status. In this large, carefully followed cohort of patients with recent lacunar stroke and aggressive blood pressure management, prior symptomatic lacunar ischemia, diabetes, black race, and male sex independently predicted ischemic stroke recurrence. The effects of blood pressure targets and dual antiplatelet therapy were similar across the spectrum of independent risk factors and recurrence risk. Copyright © 2014 National Stroke Association.

Younger patients and those with smaller hamstring autograft diameters have been shown to be at significantly greater risk of graft failure after anterior cruciate ligament (ACL) reconstruction. To date, there is no information in the literature about the clinical success and/or cost-effectiveness of increasing graft diameter by augmenting with semitendinosus allograft tissue for younger patients. Hybrid hamstring grafts are a cost-effective treatment option because of a reduced rate of graft failure. Cohort study (economic and decision analysis); Level of evidence, 3. We retrospectively identified patients younger than 18 years who had undergone ACL reconstruction by a single surgeon between 2010 and 2015. During this period, the operating surgeon's graft selection algorithm included the use of bone-patellar tendon-bone (BTB) autografts for the majority of patients younger than 18 years. However, hamstring autografts (hamstring) or hybrid hamstring autografts with allograft augment (hybrid) were used in skeletally immature patients and in those whom the surgeon felt might have greater difficulty with postoperative rehabilitation after BTB graft harvest. Patient demographics, graft type, graft diameter, the time the patient was cleared to return to activity, and the need for secondary surgical procedures were compared between the hamstring and hybrid groups. The clinical results were then used to assess the potential cost-effectiveness of hybrid grafts in this select group of young patients with an ACL injury or reconstruction. This study comprised 88 patients (hamstring group, n = 46; hybrid group, n = 42). The 2 groups did not differ in terms of age, sex, timing of return to activity, or prevalence of skeletally immature patients. Graft diameters were significantly smaller in the hamstring group (7.8 vs 9.9 mm; P < .001), which corresponded with a significantly greater rate of graft failure (13 of 46 [28.3%] vs 5 of 42 [11.9%]; P = .049).

Intravenous thrombolysis for ischaemic stroke remains underused worldwide. We aimed to assess whether our statewide comprehensive stroke management programme would improve thrombolysis use and clinical outcome in patients. In 2008-09, we designed the Tyrol Stroke Pathway, which provided information campaigns for the public and standardised the entire treatment pathway from stroke onset to outpatient rehabilitation. It was commenced in Tyrol, Austria, as a long-term routine-care programme and aimed to include all patients with stroke in the survey area. We focused on thrombolysis use and outcome in the first full 4 years of implementation (2010-13). We enrolled 4947 (99%) of 4992 patients with ischaemic stroke who were admitted to hospitals in Tyrol; 675 (14%) of the enrollees were treated with alteplase. Thrombolysis administration in Tyrol increased after programme implementation, from 160 of 1238 patients (12·9%, 95% CI 11·1-14·9) in 2010 to 213 of 1266 patients (16·8%, 14·8-19·0) in 2013 (ptrend 2010-13<0·0001). Differences in use of thrombolysis in the nine counties of Tyrol in 2010 (range, 2·2-22·6%) were reduced by 2013 (12·1-22·5%). Median statewide door-to-needle time decreased from 49 min (IQR 35-60) in 2010 to 44 min (29-60) in 2013; symptomatic post-thrombolysis intracerebral haemorrhages occurred in 28 of 675 patients (4·1%, 95% CI 2·8-5·9) during 2010-13. In four Austrian states without similar stroke programmes, thrombolysis administration remained stable or declined between 2010 and 2013 (mean reduction 14·4%, 95% CI 10·9-17·9). Although the 3-month mortality was not affected by our programme (137 [13%] of 1060 patients in 2010 vs 143 [13%] of 1069 patients in 2013), 3-month functional outcome significantly improved (modified Rankin Scale score 0-1 in 375 [40%] of 944 patients in 2010 vs 493 [53%] of 939 in 2013; score 0-2 in 531 [56%] patients in 2010 and 615 [65%] in 2013; ptrend 2010-13<0·0001).

An individualized stroke care program was developed to match patients' education with their needs regarding stroke knowledge, secondary prevention and rehabilitation. Our purpose was to assess feasibility of in-hospital and post-discharge, personalized stroke coaching service. Acute ischemic stroke patients enrolled in ASTRAL-B stroke registry (Sint-Lucashospital, Bruges Belgium) with: (a) hospitalization between 12/2014-12/2015, (b) hospital-to-home discharge, and (c) without cognitive decline, were selected. The stroke coach contacted patients individually twice during hospitalization (2×20min) and post-discharge via phone calls using the standardized WSO Post-Strokechecklist. Risk factor management, review of therapy and clinical evolution were discussed. Participants were contacted at 2 weeks, followed by repeat calls if necessary and ambulatory with the vascular neurologist at 1, 3, 6 and 12 months. Of all 255 patients meeting the inclusion criteria, 152 (59.7%) received individualized education during hospitalization by the stroke coach. Median age of our population was 74 years and median NIHSS 5. Majority of patients had at least two cardiovascular risk factors. Patients were not coached because of palliative care/decease (10%), unfavorable life expectancy (2%), dementia (8.5%) and lack of time due to short hospitalization (22%). A quarter of all patients were contacted at least once by phone, 12% were contacted at least twice after discharge. At three months, low stroke recurrence (5%) and mortality rates (4%) were identified, probably linked to improved adherence. We demonstrated feasibility of an individualized coaching service executed by well-trained stroke nurse. Future research will focus on developing an online portal delivering post-discharge services to patients and caregivers. Copyright © 2017 Elsevier B.V. All rights reserved.

Some patients with ischemic strokes that are currently classified as having an undetermined cause may have structural or functional changes of the left atrium (LA) and left atrial appendage, which increase their risk of thromboembolism. We compared the LA and left atrial appendage of patients with different ischemic stroke causes using cardiac magnetic resonance imaging. We prospectively included a consecutive sample of ischemic stroke patients. Patients with structural changes on echocardiography currently considered as causal for stroke in the Trial of ORG 10172 in Acute Stroke Treatment (TOAST) classification were excluded. A 3-T cardiac magnetic resonance imaging was performed. One hundred and eleven patients were evaluated. Patients with an undetermined cause had a higher percentage of LA fibrosis ( P =0.03) than patients with other stroke causes and lower, although not statistically significant, values of LA ejection fraction. Patients with atrial fibrillation and undetermined stroke cause showed a similar value of atrial fibrosis. The LA phenotype that was found in patients with undetermined cause supports the hypothesis that an atrial disease may be associated with stroke. © 2018 American Heart Association, Inc.

Transient ischemic attacks (TIA) are stroke warning signs and emergency situations, and, if immediately investigated, doctors can intervene to prevent strokes. Nevertheless, many patients delay going to the doctor, and doctors might delay urgently needed investigations and preventative treatments. We set out to determine how much general practitioners (GPs) and hospital physicians (HPs) knew about stroke risk after TIA, and to measure their referral rates. We used a structured questionnaire to ask GPs and HPs in the catchment area of the University Hospital of Bern to estimate a patient's risk of stroke after TIA. We also assessed their referral behavior. We then statistically analysed their reasons for deciding not to immediately refer patients. Of the 1545 physicians, 40% (614) returned the survey. Of these, 75% (457) overestimated stroke risk within 24 hours, and 40% (245) overestimated risk within 3 months after TIA. Only 9% (53) underestimated stroke risk within 24 hours and 26% (158) underestimated risk within 3 months; 78% (473) of physicians overestimated the amount that carotid endarterectomy reduces stroke risk; 93% (543) would rigorously investigate the cause of a TIA, but only 38% (229) would refer TIA patients for urgent investigations "very often". Physicians most commonly gave these reasons for not making emergency referrals: patient's advanced age; patient's preference; patient was multimorbid; and, patient needed long-term care. Although physicians overestimate stroke risk after TIA, their rate of emergency referral is modest, mainly because they tend not to refer multimorbid and elderly patients at the appropriate rate. Since old and frail patients benefit from urgent investigations and treatment after TIA as much as younger patients, future educational campaigns should focus on the importance of emergency evaluations for all TIA patients.

To study the association of time to inpatient rehabilitation hospital (IRH) admission and functional outcomes of patients who have had a stroke. A retrospective cohort study. A regional IRH. Moderately (n = 614) and severely (n = 1294) impaired patients who had a stroke who were admitted to the facility between 2002 and 2006. Not applicable. Change in total, motor, and cognitive Functional Independence Measure (FIM) scores between IRH admission and discharge. After controlling for patient demographics and initial medical conditions and functional status, shorter periods from stroke onset to IRH admission were significantly associated with greater functional gains for these patients during IRH hospitalization. Moderately impaired patients achieved a greater total FIM gain when admitted to an IRH within 21 days of stroke. Severely impaired patients showed a gradient relationship between time to IRH admission and total FIM gain, with significantly different functional gain if admitted to an IRH within 30 and 60 days after stroke diagnosis. Results of multiple regression analysis also showed that age, race/ethnicity, side of stroke, history of a previous stroke, functional measures at IRH admission, IRH length of stay, and selected medications were associated with total, motor, and cognitive FIM score changes. In addition, certain factors such as older age, diagnosis of a hemorrhagic stroke or a previous history of stroke, and initial functional status were associated with longer periods between diagnosis and admission to an IRH after the stroke occurred. Our findings are consistent with the hypothesis that earlier transfer to an IRH may lead to better functional improvement after stroke. However, certain factors such as age, race/ethnicity, initial medical conditions and functional status, and length of stay at an IRH contributed to functional gain. Factors affecting the time to IRH admission also were addressed. Copyright © 2011 American Academy of Physical Medicine

Inadequate health literacy is a pervasive problem with major implications for reduced health status and health disparities. Despite the role of focused education in both primary and secondary prevention of stroke, the effect of health literacy on stroke education retention has not been reported. We examined the relationship of health literacy to the retention of knowledge after recommended stroke education. This prospective cross-sectional study was conducted at an urban safety-net hospital. Study subjects were patients older than 18 admitted to the hospital stroke unit with a diagnosis of acute ischemic stroke who were able to provide informed consent to participate (N = 100). Health literacy levels were measured by using the short form of Test of Functional Health Literacy in Adults. Patient education was provided to patients at an inpatient stroke unit by using standardized protocols, in compliance with Joint Commission specifications. The education outcomes for poststroke care education, knowledge retention, was assessed for each subject. The effect of health literacy on the Stroke Patient Education Retention scores was assessed by using univariate and multivariate analyses. Of the 100 participating patients, 59% had inadequate to marginal health literacy. Stroke patients who had marginal health literacy (mean score, 7.45; standard deviation [SD], 1.9) or adequate health literacy (mean score, 7.31; SD, 1.76) had statistically higher education outcome scores than those identified as having inadequate health literacy (mean score, 5.58; SD, 2.06). Results from multivariate analysis indicated that adequate health literacy was most predictive of education outcome retention. This study demonstrated a clear relationship between health literacy and stroke education outcomes. Studies are needed to better understand the relationship of health literacy to key educational outcomes for primary or secondary prevention of stroke and to refine stroke education for literacy

Indications for total and unicondylar knee arthroplasty (KA) have expanded to younger patients, in which Patient-Reported Outcome Measures (PROMs) often show ceiling effects. This might be due to higher expectations. Our aims were to explore expectations of younger patients concerning activities in daily life, work and leisure time after KA and to assess to what extent PROMs meet and evaluate these activities of importance. Focus groups were performed among osteoarthritis (OA) patients <65 years awaiting KA, in which they indicated what activities they expected to perform better in daily life, work and leisure time after KA. Additionally, 28 activities of daily life, 17 of work and 27 of leisure time were depicted from seven PROMS, which were rated on importance, frequency and bother. A total score, representing motivation for surgery, was also calculated. Data saturation was reached after six focus groups including 37 patients. Younger OA patients expect to perform better on 16 activities after KA, including high-impact leisure time activities. From the PROMs, daily life and work activities were rated high in both importance and motivation for surgery, but for leisure time activities importance varied highly between patients. All seven PROMs score activities of importance, but no single PROM incorporates all activities rated important. Younger patients expect to perform better on many activities of daily life, work and leisure time after KA, and often at demanding levels. To measure outcomes of younger patients, we suggest using PROMs that include work and leisure time activities besides daily life activities, in which preferably scored activities can be individualized.

Pneumonia is one of the most frequent medical complications of a stroke. Despite the well-documented association of a stroke associated infections with increased mortality and worse long-term outcome, on the other hand, the limited data available on independent predictors of pneumonia in acute stroke patients in an emergency unit. To determine the independentrelationship between pneumonia and Glasgow Coma Scale assessment on acute stroke patients. The cohort retrospective study observed 55 acute stroke patients who stayed in intensive care unit Adam Malik General Hospital from January until August 2017. Pneumonia was more frequent in patients with Ischemic stroke (OR 5.40; 95% CI: 1.28 – 6.40, p=0.003), higher National Institute of Health Stroke Scale (NIHSS) (p=0.014) and lower Glasgow Coma Scale (p=0.0001). Analysis multivariate logistic regression identified NIHSS as an independent of predictors of pneumonia (95% CI : 1.047 – 1.326, p=0.001). Pneumonia was associated with severity and type of stroke and length of hospital stay. The severity of the deficits evaluated by the NIHSS was shown to be the only independent risk factor for pneumonia in acute stroke patients.

Dysphagia is a common problem in stroke patients with unclear pathogenesis. Several recent functional magnetic resonance imaging (fMRI) studies had been carried out to explore the cerebral functional changes in dysphagic stroke patients. The aim of this study was to analysis these imaging findings using a meta-analysis. We used seed-based d mapping (SDM) to conduct a meta-analysis for dysphagic stroke patients prior to any kind of special treatment for dysphagia. A systematic search was conducted for the relevant studies. SDM meta-analysis method was used to examine regions of increased and decreased functional activation between dysphagic stroke patients and healthy controls. Finally, six studies including 81 stroke patients with dysphagia and 78 healthy controls met the inclusion standards. When compared with healthy controls, stroke patients with dysphagia showed hyperactivation in left cingulate gyrus, left precentral gyrus and right posterior cingulate gyrus, and hypoactivation in right cuneus and left middle frontal gyrus. The hyperactivity of precentral gyrus is crucial in stroke patients with dysphagia and may be associated with the severity of stroke. Besides the motor areas, the default-mode network regions (DMN) and affective network regions (AN) circuits are also involved in dysphagia after stroke. © 2017 Chinese Cochrane Center, West China Hospital of Sichuan University and John Wiley & Sons Australia, Ltd.

Neurofeedback training involves presenting an individual with a representation of their brain activity and instructing them to alter the activity using the feedback. One potential application of neurofeedback is for patients to alter neural activity to improve function. For example, there is evidence that greater laterality of movement-related activity is associated with better motor outcomes after stroke; so using neurofeedback to increase laterality may provide a novel route for improving outcomes. However, we must demonstrate that individuals can control relevant neurofeedback signals. Here, we performed two proof-of-concept studies, one in younger (median age: 26years) and one in older healthy volunteers (median age: 67.5years). The purpose was to determine if participants could manipulate laterality of activity between the motor cortices using real-time fMRI neurofeedback while performing simple hand movements. The younger cohort trained using their left and right hand, the older group trained using their left hand only. In both studies participants in a neurofeedback group were able to achieve more lateralized activity than those in a sham group (younger adults: F(1,23)=4.37, p<0.05; older adults: F(1,15)=9.08, p<0.01). Moreover, the younger cohort was able to maintain the lateralized activity for right hand movements once neurofeedback was removed. The older cohort did not maintain lateralized activity upon feedback removal, with the limitation being that they did not train with their right hand. The results provide evidence that neurofeedback can be used with executed movements to promote lateralized brain activity and thus is amenable for testing as a therapeutic intervention for patients following stroke.

Abstract Stroke is one of the most common causes of physical disability, and early, intensive, and repetitive rehabilitation exercises are crucial to the recovery of stroke survivors. Unfortunately, research shows that only one third of stroke patients actually perform recommended exercises at home, because of the repetitive and mundane nature of conventional rehabilitation exercises. Thus, to motivate stroke survivors to engage in monotonous rehabilitation is a significant issue in the therapy process. Game-based rehabilitation systems have the potential to encourage patients continuing rehabilitation exercises at home. However, these systems are still rarely adopted at patients’ places. Discovering and eliminating the obstacles in promoting game-based rehabilitation at home is therefore essential. For this purpose, we conducted a study to collect and analyze the opinions and expectations of stroke patients and clinical therapists. The study is composed of 2 parts: Rehab-preference survey – interviews to both patients and therapists to understand the current practices, challenges, and expectations on game-based rehabilitation systems; and Rehab-compatibility survey – a gaming experiment with therapists to elaborate what commercial games are compatible with rehabilitation. The study is conducted with 30 outpatients with stroke and 19 occupational therapists from 2 rehabilitation centers in Taiwan. Our surveys show that game-based rehabilitation systems can turn the rehabilitation exercises more appealing and provide personalized motivation for various stroke patients. Patients prefer to perform rehabilitation exercises with more diverse and fun games, and need cost-effective rehabilitation systems, which are often built on commodity hardware. Our study also sheds light on incorporating the existing design-for-fun games into rehabilitation system. We envision the results are helpful in developing a platform which enables rehab-compatible (i.e., existing

Obesity is well recognized as a risk factor for coronary heart disease and mortality. The relationship between abdominal obesity and ischemic stroke remains less clear. Our aim was to evaluate abdominal obesity as an independent risk factor for ischemic stroke in a multiethnic community. A population-based, incident case-control study was conducted July 1993 through June 1997 in northern Manhattan, New York, NY. Cases (n=576) of first ischemic stroke (66% >or=BORDER="0">65 years of age; 56% women; 17% whites; 26% blacks; 55% Hispanics) were enrolled and matched by age, sex, and race-ethnicity to stroke-free community controls (n=1142). All subjects were interviewed and examined and had measurements of waist-to-hip ratio (WHR). Odds ratios (ORs) of ischemic stroke were calculated with gender-specific quartiles (GQs) and gender-specific medians of WHR adjusted for stroke risk factors and body mass index (BMI). Compared with the first quartile, the third and fourth quartiles of WHR had an increased risk of stroke (GQ3: OR, 2.4; 95% CI, 1.5 to 3.9; GQ4: OR, 3.0; 95% CI, 1.8 to 4.8) adjusted for other risk factors and BMI. Those with WHR equal to or greater than the median had an overall OR of 3.0 (95% CI, 2.1 to 4.2) for ischemic stroke even after adjustment for other risk factors and BMI. Increased WHR was associated with a greater risk of stroke in men and women and in all race-ethnic groups. The effect of WHR was stronger among younger persons (test for heterogeneity, P<0.0002) (<65 years of age: OR, 4.4; 95%CI, 2.2 to 9.0; >or=65 years of age: OR, 2.2; 95% CI, 1.4 to 3.2). WHR was associated with an increased risk among those with and without large-artery atherosclerotic stroke. Abdominal obesity is an independent, potent risk factor for ischemic stroke in all race-ethnic groups. It is a stronger risk factor than BMI and has a greater effect among younger persons. Prevention of obesity and weight reduction need greater emphasis in stroke prevention programs.

To identify case fatality rates and predictors of stroke in a private clinic in Kinshasa, Democratic Republic of Congo. Two hundred and twelve black Africans were consecutively admitted to a clinic and prospectively assessed during the first 30 days by CT scan-proven stroke types and outcome. Univariate and multivariate analyses were used to estimate the in-hospital mortality risk for the following baseline characteristics: age, gender, education, arterial hypertension, diabetes, stroke types, leukocyte count, and haematocrit, blood glucose, uric acid, fibrinogen and total cholesterol levels. Haemorrhagic and ischaemic strokes were present in 52 and 48% of the study population, respectively; and 44% of all stroke type patients, 29% of haemorrhagic stroke and 31% of ischaemic stroke patients died. Compared to the survivors, deceased patients were significantly (p < 0.001) older with higher leukocyte counts and haematocrit, haemoglobin and fibrinogen levels, but lower glycaemic levels. The variable significantly associated with all stroke type mortalities in the multivariate model was ischaemic stroke (HR = 4.28, p < 0.001). The univariate risk factors of mortality in patients with ischaemic stroke were higher fibrinogenaemia (RR = 6.4; 95% CI = 4.8-8.2 for tertile 3 and RR = 12.9; 95% CI = 7.8-18.4 for tertile 4; p < 0.001) and higher glycaemia (RR = 3.3; 95% CI = 1.4-5.7 for tertile 3 and RR = 6.7; 95% CI = 5.2-9.2 for tertile 4; p < 0.001). We have shown that all acute stroke types remain a deadly nosological entity, and ischaemic stroke, baseline haematocrit and fibrinogen levels, and dependency on others' care were significantly associated with all stroke mortalities. Moreover, hyperfibrinogaemia and hyperglycaemia were the significant predictors of case fatality in ischaemic stroke patients. In Africa, the top priority for resource allocation for stroke services should go to the primary prevention of stroke.

To explore varied forms of psychological distress and to determine the mediating influence of psychological distress on functional outcomes in stroke patients. Previous studies attest to the influence of depression on poststroke functional recovery. While there is evidence for neuropathological deficits that occur after stroke to be associated with psychological distress, few studies have explored the effect of various types of psychological distress on functional recovery. A cross-sectional study was used. Data were collected from 178 first-time stroke patients. Study variables included demographic and disease characteristics (stroke location and stroke syndrome classification), psychological distress (the Chinese language version of the Emotional and Social Dysfunction Questionnaire) and functional outcome (Barthel index). Regression and mediation models were used to evaluate the effect of psychological distress on functional outcome. Results revealed that stroke patients experience various forms of mild psychological distress, including anger, helplessness, emotional dyscontrol, indifference, inertia and euphoria, after stroke. Regression and mediation analyses further confirmed that various forms of psychological distress significantly mediated the effect of severe stroke syndromes on functional dependence. The various forms of psychological distress after stroke might play a mediating role in functional recovery and explain how stroke severity affects functional dependence. By understanding the nature of various forms of psychological distress, healthcare professionals should adopt appropriate assessment instruments and design effective interventions to help improve mental and physical function of stroke patients. © 2014 John Wiley & Sons Ltd.

Data on effects of intravenous thrombolysis on outcome of patients with ischemic stroke who are dependent on assistance in activities of daily living prestroke are scarce. Recent registry based analyses in activities of daily -independent patients suggest that earlier start of intravenous thrombolysis in the prehospital setting leads to better outcomes when compared with the treatment start in hospital. We evaluated whether these observations can be corroborated in patients with prestroke dependency. This observational, retrospective analysis included all patients with acute ischemic stroke depending on assistance before stroke who received intravenous thrombolysis either on the Stroke Emergency Mobile (STEMO) or through conventional in-hospital care (CC) in a tertiary stroke center (Charité, Campus Benjamin Franklin, Berlin) during routine care. Prespecified outcomes were modified Rankin Scale scores of 0 to 3 and survival at 3 months, as well as symptomatic intracranial hemorrhage. Outcomes were adjusted in multivariable logistic regression. Between February 2011 and March 2015, 122 of 427 patients (28%) treated on STEMO and 142 of 505 patients (28%) treated via CC needed assistance before stroke. Median onset-to-treatment times were 97 (interquartile range, 69-159; STEMO) and 135 (interquartile range, 98-184; CC; P <0.001) minutes. After 3 months, modified Rankin Scale scores of 0 to 3 was observed in 48 STEMO patients (39%) versus 35 CC patients (25%; P =0.01) and 86 (70%, STEMO) versus 85 (60%, CC) patients were alive ( P =0.07). After adjustment, STEMO care was favorable with respect to modified Rankin Scale scores of 0 to 3 (odds ratio, 1.99; 95% confidence interval, 1.02-3.87; P =0.042) with a nonsignificant result for survival (odds ratio, 1.73; 95% confidence interval, 0.95-3.16; P =0.07). Symptomatic intracranial hemorrhage occurred in 5 STEMO versus 12 CC patients (4.2% versus 8.5%; P =0.167). The results of this study suggest that earlier, prehospital

Background and Purpose Ventricular assist devices (VADs) have advanced the management of end-stage heart failure. However, these devices are associated with hemorrhagic and thrombotic complications, including stroke. We assessed the incidence, risk factors, and outcomes of ischemic and hemorrhagic stroke after VAD placement. Methods Using administrative claims data from acute care hospitals in California, Florida, and New York from 2005–2013, we identified patients who underwent VAD placement, defined by International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) code 37.66. Ischemic and hemorrhagic strokes were identified by previously validated coding algorithms. We used survival statistics to determine incidence rates and Cox proportional hazard analyses to examine associations. Results Among 1,813 patients, we identified 201 ischemic strokes and 116 hemorrhagic strokes during 3.4 (±2.0) years of follow-up after implantation of a VAD. The incidence of stroke was 8.7% per year (95% confidence interval [CI], 7.7–9.7%). The annual incidence of ischemic stroke (5.5%; 95% CI, 4.8–6.4%) was nearly double that of hemorrhagic stroke (3.1%; 95% CI, 2.6–3.8%). Women faced a higher hazard of stroke than men (hazard ratio [HR], 1.6; 95% CI, 1.2–2.1), particularly hemorrhagic stroke (HR, 2.2; 95% CI, 1.4–3.4). Stroke was strongly associated with subsequent in-hospital mortality (HR, 6.1; 95% CI, 4.6–7.9). Conclusions The incidence of stroke after VAD implantation was 8.7% per year, and incident stroke was strongly associated with subsequent in-hospital mortality. Notably, ischemic stroke occurred at nearly twice the rate of hemorrhagic stroke. Women appeared to face a higher risk for hemorrhagic stroke than men. PMID:27650070

Impaired motor and functional activity following stroke often has negative impacts on the patient, the family and society. The available rehabilitation programs for stroke patients are reviewed. Conventional rehabilitation strategies (Bobath, Brunnstrom, proprioception neuromuscular facilitation, motor relearning and function-based principles) are the mainstream tactics in clinical practices. Numerous advanced strategies for sensory-motor functional enhancement, including electrical stimulation, electromyographic biofeedback, constraint-induced movement therapy, robotics-aided systems, virtual reality, intermittent compression, partial body weight supported treadmill training and thermal stimulation, are being developed and incorporated into conventional rehabilitation programs. The concept of combining valuable rehabilitative procedures into “a training package”, based on the patient’s functional status during different recovery phases after stroke is proposed. Integrated sensorimotor rehabilitation programs with appropriate temporal arrangements might provide great functional benefits for stroke patients. PMID:25133141

Purpose. The aim of this study was to describe the experience of return to work (RTW) after stroke from the patient's perspective.Method. Six patients who had their first ever stroke in 2001, were <65 years of age and were working at the time of their stroke were included. Information was obtained via an open-ended interview. The material was transcribed verbatim and analysed using Giorgi's empirical phenomenology.Results. Rehabilitation was perceived as primarily aimed at restoring bodily functions and a return to everyday activities, rather than at promoting a return to work. It was not experienced as adapted to the participants' needs or their age. The workplace was experienced as very important in the rehabilitation process. When the informants experienced that the rehabilitation professionals were not taking action, they took control of the situation themselves. The informants expressed pride in their own capacity to take the initiative and in their ability to take action. Both self-employed and employed informants said they had possibilities and opportunities to take action since their work situation was flexible. The informants' adaptation to a new role at work was perceived as facilitated by the understanding and positive attitude of co-workers.Conclusion. Among this group of stroke patients, the individual patient's capacity and ability to return to work was enhanced by motivation or "will" and self-efficacy in combination with external support. Self-efficacy was not only a personal trait or internal factor; it was enhanced and encouraged in interaction with contextual conditions. There are similarities between the RTW process and processes of health promotion.

Introduction. Our aim was to analyze our clinical experience with dabigatran etexilate in secondary stroke prevention. Methods. We retrospectively included patients starting dabigatran etexilate for secondary stroke prevention from March 2010 to December 2012. Efficacy and safety variables were registered. Results. 106 patients were included, median follow-up of 12 months (range 1–31). Fifty-six females (52.8%), mean age 76.4 (range 50–95, SD 9.8), median CHADS2 4 (range 2–6), CHA2DS2-VASc 5 (range 2–9), and HAS-BLED 2 (range 1–5). Indication for dabigatran etexilate was ischemic stroke in 101 patients and acute cerebral hemorrhage (CH) due to warfarin in 5 (4.7%). Dabigatran etexilate 110 mg bid was prescribed in 71 cases (67%) and 150 mg bid was prescribed in the remaining. Seventeen patients (16%) suffered 20 complications during follow-up. Ischemic complications (10) were 6 transient ischemic attacks (TIA), 3 ischemic strokes, and 1 acute coronary syndrome. Hemorrhagic complications (10) were CH (1), gastrointestinal bleeding (6), mild hematuria (2), and mild metrorrhagia (1), leading to dabigatran etexilate discontinuation in 3 patients. Patients with previous CH remained uneventful. Three patients died (pneumonia, congestive heart failure, and acute cholecystitis) and 9 were lost during follow-up. Conclusions. Dabigatran etexilate was safe and effective in secondary stroke prevention in clinical practice, including a small number of patients with previous history of CH. PMID:25133166

Diagnostic testing for coagulopathies in patients with ischemic stroke.

Bushnell, C D; Goldstein, L B

Hypercoagulable states are a recognized, albeit uncommon, etiology of ischemic stroke. It is unclear how often the results of specialized coagulation tests affect management. Using data compiled from a systematic review of available studies, we employed quantitative methodology to assess the diagnostic yield of coagulation tests for identification of coagulopathies in ischemic stroke patients. We performed a MEDLINE search to identify controlled studies published during 1966-1999 that reported the prevalence of deficiencies of protein C, protein S, antithrombin III, plasminogen, activated protein C resistance (APCR)/factor V Leiden mutation (FVL), anticardiolipin antibodies (ACL), or lupus anticoagulant (LA) in patients with ischemic stroke. The cumulative prevalence rates (pretest probabilities) and positive likelihood ratios for all studies and for those including only patients aged stroke patients are as follows: LA, 3% (8% for those aged patients' history and clinical presentation. The pretest probabilities of coagulation defects in ischemic stroke patients are low. The diagnostic yield of coagulation tests may be increased by using tests with the highest specificities and by targeting patients with clinical or historical features that increase pretest probability. Consideration of these data might lead to more rational ordering of tests and an associated cost savings.

Stroke can occur in patients on warfarin despite anticoagulation. Patients with a low international normalized ratio (INR) should theoretically be at greater risk for ischemia than those who are therapeutic. Therefore, INR may be able to indicate whether new neurological deficits are more likely strokes or stroke mimics in patients on warfarin. This study evaluates the association and predictive value of INR in determining the likelihood of ischemia. Patients were identified using the acute stroke registry at a Primary Stroke Center from January 2013 through December 2014. All adult patients undergoing evaluation for acute stroke with prior documented use of warfarin and an INR level at presentation were included. Data were collected regarding patient demographics, medical comorbidities, stroke severity, reason for anticoagulation, and laboratory studies including INR. Student t tests and χ2 analysis were used to evaluate factors associated with increased likelihood of ischemia (stroke or transient ischemic attack) versus mimic. Significant results were entered into a multivariable regression analysis. Sensitivity and specificity analyses were conducted to determine the predictive value of INR for ischemic risk. 116 patients were included; 46 were diagnosed with ischemia, 70 were diagnosed as mimics. 75% of patients were on warfarin for atrial fibrillation versus 25% for venous thrombosis. A statistically significant difference in mean INR for patients with ischemia (n = 46) versus mimics (n = 70) was observed (1.7 vs. 2.8; p < 0.001). In multivariable analysis, both sub-therapeutic INR (p < 0.001) and atrial fibrillation (p = 0.014) were predictors of ischemia. In patients with an INR ≥2, the predictive value of having a non-ischemic etiology was 79%. No patient with an INR of ≥3.6 was found to have ischemia. Sub-therapeutic INR and atrial fibrillation are strongly associated with ischemia in patients on warfarin presenting with acute neurologic symptoms

The review is devoted to the current state of the problem of early rehabilitation of stroke patients. The rate of primary disability in patients after stroke is 3.2 per 10000 population but only 20% of previously working patients return to work. Early rehabilitation is treatment actions during a period following stroke. Adequate treatment during this period may decrease the extent of brain damage and improve disease outcome. The complexity of rehabilitation consists in using several complementary pharmacological and non-pharmacological rehabilitation measures. Appearance of new techniques of rehabilitation treatment aimed at neuroplasticity stimulation increases treatment potential of rehabilitative technologies.

The purpose of this study is to identify whether depression and other associated factors in stroke are related to subsequent hip fracture. There are very few studies that focus on depression and demographic impact on subsequent hip fracture after a stroke. This a retrospective cohort study design. The Taiwan Longitudinal Health Insurance Database between 1997 and 2010 was used. Two stroke patient cohorts were analysed: (1) depression within 1 year after newly diagnosed strokes; (2) without depression within 1 year after newly diagnosed strokes. Demographic characteristics, comorbidities, and hip fracture were compared using the Fine and Gray regression model for subdistribution hazard ratios. Patients with depression showed a higher risk of hip fracture (95% CI, 0.99-1.66). Depression was associated with increased risk of hip fracture for patients below 50 years old (95% CI, 1.45-7.34). Comorbidities and gender showed no significant correlation with hip fracture risk in the depressed or nondepressed groups. Poststroke depression was a significant contributor to hip fracture in patients who suffered strokes and had more negative impact on the younger population, regardless of the gender and presence of comorbidities. © 2018 John Wiley & Sons Australia, Ltd.

Intravenous nicardipine is generally used to treat hypertension in acute stroke patients but is associated with frequent phlebitis. We aimed to identify the incidence and risk factors of phlebitis in such patients. The incidence and risk factors of phlebitis were investigated in 358 acute stroke patients from July 2014 to June 2015. In total, 138 patients received intravenous nicardipine. Of 45 (12.6%) phlebitis patients in 358 acute stroke patients, 42 (93.3%) were administered nicardipine, which was significantly associated with phlebitis occurrence (P < .01). Other candidate risk factors of phlebitis of acute stroke patients in univariate analysis were intracerebral hemorrhage (P < .01), nicardipine injection to paralyzed limbs (P = .023), dilution of nicardipine with normal saline (P < .01), higher maximum flow rate of nicardipine (7.2 ± 4.1 mg/h versus 1.6 ± 3.1 mg/h; P < .01), and higher maximum concentration of nicardipine (271.5 ± 145.0 µg/mL versus 37.6 ± 75.0 µg/mL; P < .01). The only statistically significant independent factor following multivariate logistic regression analysis, according to the optimal cutoff values defined from receiver operating characteristic curve analyses, was the maximum concentration of nicardipine greater than 130 µg/mL (OR 57.9; 95% CI 21.5-156; P < .01). A gradual decline of pH below 4.3 was observed when the concentration of nicardipine solution increased to greater than or equal to 130 µg/mL in vitro. Nicardipine-related phlebitis is frequently observed in acute stroke patients and is significantly associated with administration of a maximum concentration of nicardipine greater than 130 µg/mL.

Dignity is seen as an important but complex concept in the healthcare context. In this context, the discussion of dignity includes concepts of other ethical principles such as autonomy and privacy. Patients consider dignity to cover individuality, patient's feelings, communication, and the behavior of healthcare personnel. However, there is a lack of knowledge concerning the realization of patients' dignity in hospital care and the focus of the study is therefore on the realization of dignity of the vulnerable group of patients with stroke. The aim of the study was to create a theoretical construct to describe the dignity realization of patients with stroke in hospital care. Research design and participants: Patients with stroke (n = 16) were interviewed in 2015 using a semi-structured interview containing open questions concerning dignity. The data were analyzed using constant comparison of Grounded Theory. Ethical considerations: Ethical approval for the research was obtained from the Ethics Committee of the University. The permission for the research was given by the hospital. Informed consent was obtained from participants. The "Theory of Dignity Realization of Patients with Stroke in Hospital Care" consists of a core category including generic elements of the new situation and dignity realization types. The core category was identified as "Dignity in a new situation" and the generic elements as health history, life history, individuality and stroke. Dignity of patients with stroke is realized through specific types of realization: person-related dignity type, control-related dignity type, independence-related dignity type, social-related dignity type, and care-related dignity type. The theory has similar elements with the previous literature but the whole construct is new. The theory reveals possible special characteristics in dignity realization of patients with stroke. For healthcare personnel, the theory provides a frame for a better understanding and

To conduct a survey of the clinical nursing practice in European countries in accordance with the European Stroke Strategies 2006 and to examine to what extent the European Stroke Strategies have been implemented in stroke care nursing in Europe. Stroke is a leading cause of death and disability globally. Optimal organisation of interdisciplinary stroke care is expected to ameliorate outcome after stroke. Consequently, universal access to stroke care based on evidence-based guidelines is a priority. This study is a descriptive cross-sectional survey. A questionnaire comprising 61 questions based on the European Stroke Strategies and scientific evidence in nursing practice was distributed to representatives of the European Association of Neuroscience Nurses, who sent the questionnaire to nurses active in stroke care. The questionnaire covered the following areas of stroke care: organisation of stroke services, management of acute stroke and prevention including basic care and nursing, and secondary prevention. Ninety-two nurses in stroke care in 11 European countries participated in the survey. Within the first 48 hr after stroke onset, 95% monitor patients regularly, 94% start mobilisation after 24 hr when patients are stable, and 89% assess patients' ability to swallow. Change of position for immobile patients is followed by 73%, and postvoid residual urine volume is measured by 85%. Some aspects needed improvement, for example, staff education (70%), education for patients/families/carers (55%) and individual care plans in secondary prevention (62%). The participating European countries comply well with the European Stroke Strategies guidelines, particularly in the acute stroke care, but not all stroke units have reached optimal development in all aspects of stroke care nursing. Our study may provide clinical administrators and nurses in stroke care with information that may contribute to improved compliance with the European Stroke Strategies and evidence

Duchenne muscular dystrophy (DMD) is the most frequent skeletal muscle myopathy. Nearly all patients develop cardiomyopathy in their second decade of life. The purpose of this study was to evaluate the frequency, cause, and outcome of stroke in a German cohort of patients with DMD. Retrospective analysis of medical records of 54 DMD patients, who lived in a regional facility for handicapped people (Wichernhaus Altdorf, Germany) between 1963 and 2013. Fifty-four DMD patients were followed up for 7.4 years on average. Mean age at admission and discharge from the long-term care facility or death were 11.4 and 18.8 years, respectively. Covering a total observation period of 400 patient-years, we identified 4 DMD patients with juvenile arterial ischemic strokes. Off-label systemic thrombolysis in 2 patients resulted in a nearly complete regression of stroke-related symptoms, but 1 patient died of septic pneumonia and cardiac failure 24 days after thrombolysis therapy. In the other 2 patients, who had their ischemic strokes in 1994 and 1998, severe infarction-related symptoms persisted, and 1 patient died 13 days later. DMD-associated cardiomyopathy without evidence of atrial fibrillation was the only risk factor for ischemic stroke in all patients. This study indicates an increased risk for ischemic strokes in DMD patients. Regular cardiological assessment of all DMD patients is mandatory to evaluate the individual risk profile for cardioembolic events and to adapt therapeutic strategies. © 2016 American Heart Association, Inc.

To determine racial and gender differences in long-term survival following ischemic stroke in a well-defined cohort of patients. We analyzed the prospectively collected data from a randomized, placebo-controlled trial in patients with ischemic stroke presenting within 3 hours of symptom onset. We determined the effect of race and gender on 1-year survival ascertained by serial follow-ups using Kaplan-Meier analysis. Multivariate analysis was performed adjusting for age, initial NIH Stroke Scale (NIHSS) score, use of thrombolysis, time to randomization, stroke etiology, and other cardiovascular risk factors. Of the 547 patients with ischemic stroke, the 1-year survival (percentage +/- SE) for African American women (63 +/- 6%) was lower than white women (73 +/- 4%), African American men (79 +/- 4%), and white men (75 +/- 3%). Among the 209 patients younger than 65 years, the 1-year survival was prominently lower for African American women (66 +/- 8%) vs white women (87 +/- 5%), African American men (83 +/- 5%), and white men (89 +/- 3%). In the Cox proportional hazard analysis, African American women had a significantly higher rate of 1-year mortality (relative risk 2.1, 95% CI 1.2 to 3.5) after adjusting for all potential confounders except diabetes mellitus. After adjustment for diabetes mellitus, the difference became insignificant, although a 70% greater risk of 1-year mortality was still observed. Compared with whites and men, African American women have a lower 1-year survival following ischemic stroke.

Functional MRI (fMRI) is well-established for the study of brain function in healthy populations, although its clinical application has proven more challenging. Specifically, cerebrovascular reactivity (CVR), which allows the assessment of the vascular response that serves as the basis for fMRI, has been shown to be reduced in healthy aging as well as in a range of diseases, including chronic stroke. However, the timing of when this occurs relative to the stroke event is unclear. We used a breath-hold fMRI task to evaluate CVR across gray matter in a group of acute stroke patients (< 10 days from stroke; N = 22) to address this question. These estimates were compared with those from both age-matched (N = 22) and younger (N = 22) healthy controls. As expected, young controls had the greatest mean CVR, as indicated by magnitude and extent of fMRI activation; however, stroke patients did not differ from age-matched controls. Moreover, the ipsilesional and contralesional hemispheres of stroke patients did not differ with respect to any of these measures. These findings suggest that fMRI remains a valid tool within the first few days of a stroke, particularly for group fMRI studies in which findings are compared with healthy subjects of similar age. However, given the relatively high variability in CVR observed in our stroke sample, caution is warranted when interpreting fMRI data from individual patients or a small cohort. We conclude that a breath-hold task can be a useful addition to functional imaging protocols for stroke patients.
