    The major therapy for ischemic stroke is thrombolytic treatment, but severe consequences occur when this method is used to treat hemorrhagic stroke. Currently, computed tomography and magnetic resonance imaging are used to differentiate between two types of stroke, but these two methods are ineffective for pre-hospital care. We developed a new brain diagnostic device for rabbits based on electromagnetic induction to non-invasively differentiate two types of stroke. The device includes two coils and a phase difference measurement system that detects the magnetic inductive phase shift (MIPS) value to reflect the tissue's condition. The hemorrhage model was established through the injection of autologous blood into the internal capsule of a rabbit's brain. Ischemia was induced in the brain of a rabbit by bilateral carotid artery occlusion. Two types of animal models were measured with our device. The MIPS value gradually decreased with increasing injected blood and increased with ischemia time. The MIPS changes induced by the two types of strokes were exact opposites, and the absolute values of MIPS variation in the hemorrhagic and the ischemic groups were significantly larger than those of the normal control group (P stroke from hemorrhagic stroke on rabbit brain in a non-invasive, continuous, and bulk monitoring manner by using a simple and inexpensive apparatus.

    Full Text Available Cryptogenic stroke is defined as brain infarction that is not attributable to a source of definite embolism, large artery atherosclerosis, or small artery disease despite a thorough vascular, cardiac, and serologic evaluation. Despite many advances in our understanding of ischemic stroke, cryptogenic strokes remain a diagnostic and therapeutic challenge. The pathophysiology of cryptogenic stroke is likely various. Probable mechanisms include cardiac embolism secondary to occult paroxysmal atrial fibrillation, aortic atheromatous disease or other cardiac sources, paradoxical embolism from atrial septal abnormalities such as patent foramen ovale, hypercoagulable states, and preclinical or subclinical cerebrovascular disease.  Cryptogenic stroke is one-fourth among cerebral infarction, but most of them could be ascribed to embolic stroke. A significant proportion of cryptogenic strokes adhere to embolic infarct topography on brain imaging and improvement in our ability to detect paroxysmal atrial fibrillation in patients with cryptogenic stroke has strengthened the idea that these strokes are embolic in nature. a significant proportion of cryptogenic strokes adhere to embolic infarct topography on brain imaging.embolic stroke of undetermined sources(ESUS was planned for unifying embolic stroke of undetermined source.  The etiologies underlying ESUS included minor-risk potential cardioembolic sources, covert paroxysmal atrial fibrillation, cancer-associated coagulopathy and embolism, arteriogenic emboli, and paroxysmal embolism. Extensive evaluation including transesophageal echocardiography and cardiac monitoring for long time could identify the etiology of these patients. Therefore cryptogenic stroke is a diagnosis of exclusion. Compared with other stroke subtypes, cryptogenic stroke tends to have a better prognosis and lower long-term risk of recurrence.

The objective of this study was to examine the validity of the registration of patients in a stroke-specific registry...... (The Danish Stroke Registry [DSR]) and a hospital discharge registry (The Danish National Patient Registry [DNRP]). METHODS: Assuming that all patients with stroke were registered in either the DSR, DNRP or both, we first identified a sample of 75 patients registered with stroke in 2009; 25 patients...... in the DSR, 25 patients in the DNRP, and 25 patients registered in both data sources. Using the medical record as a gold standard, we then estimated the sensitivity and positive predictive value of a stroke diagnosis in the DSR and the DNRP. Secondly, we reviewed 160 medical records for all potential stroke...

    Stroke is a common, serious, and disabling global health-care problem, and rehabilitation is a major part of patient care. There is evidence to support rehabilitation in well coordinated multidisciplinary stroke units or through provision of early supported provision of discharge teams. Potentially beneficial treatment options for motor recovery of the arm include constraint-induced movement therapy and robotics. Promising interventions that could be beneficial to improve aspects of gait include fitness training, high-intensity therapy, and repetitive-task training. Repetitive-task training might also improve transfer functions. Occupational therapy can improve activities of daily living; however, information about the clinical effect of various strategies of cognitive rehabilitation and strategies for aphasia and dysarthria is scarce. Several large trials of rehabilitation practice and of novel therapies (eg, stem-cell therapy, repetitive transcranial magnetic stimulation, virtual reality, robotic therapies, and drug augmentation) are underway to inform future practice.

  12. Prevention Of Stroke

    Directory of Open Access Journals (Sweden)

    Full Text Available Stroke is an important cause for neurological morbidity and mortality. Prevention of ischemic stroke involves identification and prevention of risk factors and optimal use of pharmacotherapy. Risk factors have been classified as modifiable and non-modifiable; control of modifiable factors should prevent stroke occurrence. Stroke prevention has been described at three levels: primary, secondary and tertiary. Prolonged hypertension increases an individual′s risk for developing fatal or nonfatal stroke by three times and its control has been shown to prevent stroke. Diabetes mellitus is an important cause for microangiopathy and predisposes to stroke. Statin trials have shown significant reduction in stroke in those who were treated with statins. Stroke risk can be reduced by avoiding tobacco use, control of obesity and avoiding sedentary life style. Anti platelet medications are effective for secondary prevention of stroke. Educating society regarding modifiable risk factors and optimal use of pharmacotherapy form the cornerstone for the prevention of stroke.

    2011-01-01

    Background and Purpose Low thrombolysis rates for acute ischemic stroke is linked to delays in seeking immediate treatment due to low public stroke awareness. We aimed to assess whether “Child-Mediated Stroke Communication” (CMSC) could improve stroke literacy parents of children enrolled in a school-based stroke literacy program called Hip Hop Stroke (HHS). Methods Parents of children aged 9 to 12 years from two public schools in Harlem, NYC, were recruited to participate in stroke literacy questionnaires before and after their child’s participation in HHS, a novel CMSC intervention delivered in school auditoriums. Parental recall of stroke information communicated through their child was assessed 1-week following the intervention. Results Fifth and Sixth grade students (n =182) were enrolled into HHS. 102 parents were approached in person to participate; 75 opted to participate and 71 completed both pretest and post-test (74% response rate and 95% retention rate). Parental stroke literacy improved after the program: before the program, 3 parents of 75 (3.9%) were able to identify the five cardinal stroke symptoms, distracting symptom (chest pains), and had an urgent action plan (calling 911), compared to 21 of 71 parents (29.6%) post-intervention (pstroke signs and symptoms remains low among residents of this high-risk population. The use of Child-Mediated Stroke Communication suggests that schoolchildren aged 9-12 may be effective conduits of critical stroke knowledge to their Parents. PMID:22033995

    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.

    Full Text Available Background. Stroke mortality in Brazil is one of the highest among Western countries. Nonetheless, stroke outcome determinants are still poorly known in this country. In this study we evaluate outcome determinants of stroke in a primary stroke center in São Paulo, Brazil. Methods. We evaluated demographic, clinical, and outcome data of patients with ischemic stroke (IS, transient ischemic attack (TIA, and intracerebral hemorrhage (ICH admitted at “Hospital Paulistano,” São Paulo, Brazil. In-hospital mortality and functional outcome determinants were assessed. Univariate and binary logistic regression analysis were performed. Results. Three hundred forty-one patients were included in the study, 52.2% being male with 66.8±15.7 years. The stroke type distribution was IS: 59.2%, TIA: 29.6%, and ICH: 11.1%. ICH was associated with greater severity and poorer functional outcome. The determinants of poorer functional outcome were higher NIHSS, lower Glasgow score, and lower oxygen saturation level. The most important mortality determinant was the presence of visual symptoms. Conclusions. The stroke mortality and stroke outcome determinants found in the present study do not remarkably differ from studies carried out in developed countries. Stroke prognosis studies are crucial to better understand the high burden of stroke in Brazil.

  3. The Tracer Gas Method of Determining the Charging Efficiency of Two-stroke-cycle Diesel Engines

    Science.gov (United States)

    Schweitzer, P H; Deluca, Frank, Jr

    1942-01-01

    A convenient method has been developed for determining the scavenging efficiency or the charging efficiency of two-stroke-cycle engines. The method consists of introducing a suitable tracer gas into the inlet air of the running engine and measuring chemically its concentration both in the inlet and exhaust gas. Monomethylamine CH(sub 3)NH(sub 2) was found suitable for the purpose as it burns almost completely during combustion, whereas the "short-circuited" portion does not burn at all and can be determined quantitatively in the exhaust. The method was tested both on four-stroke and on two-stroke engines and is considered accurate within 1 percent.

    Ekstam, Lisa; Johansson, Ulla; Guidetti, Susanne; Eriksson, Gunilla; Ytterberg, Charlotte

    2015-01-01

    Objectives The aim of the study was to explore the associations between the dyad’s (person with stroke and informal caregiver) perception of the person with stroke’s rehabilitation needs and stroke severity, personal factors (gender, age, sense of coherence), the use of rehabilitation services, amount of informal care and caregiver burden. Further, the aim was to explore the personal experience of everyday life changes among persons with stroke and their caregivers and their strategies for handling these 1 year after stroke. Design A mixed methods design was used combining quantitative and qualitative data and analyses. Setting Data were mainly collected in the participants’ homes. Outcome measures Data were collected through established instruments and open-ended interviews. The dyad's perceptions of the person with stroke’s rehabilitation needs were assessed by the persons with stroke and their informal caregivers using a questionnaire based on Ware’s taxonomy. The results were combined and classified into three groups: met, discordant (ie, not in agreement) and unmet rehabilitation needs. To assess sense of coherence (SOC) in persons with stroke, the SOC-scale was used. Caregiver burden was assessed using the Caregiver Burden Scale. Data on the use of rehabilitation services were obtained from the computerised register at the Stockholm County Council. Participants 86 persons with stroke (mean age 73 years, 38% women) and their caregivers (mean age 65 years, 40% women). Results Fifty-two per cent of the dyads perceived that the person with stroke’s need for rehabilitation was met 12 months after stroke. Met rehabilitation needs were associated with less severe stroke, more coping strategies for solving problems in everyday activities and less caregiver burden. Conclusions Rehabilitation interventions need to focus on supporting the dyads’ process of psychological and social adaptation after stroke. Future studies need to explore and evaluate

    Ischemic stroke is the third leading cause of death and disability in human. The vitally important problem after ischemic stroke is hemiparesis of the body. The most common methods used in improving the mobility of patients after ischemic stroke is a Bobath-NDT (Neuro-Developmental Treatment - Bobath), which initiated the Berta and Karel Bobath for children with cerebral palsy. It is a method designed to neurophysiological recovery of these vital functions that the patient was lost due to illness, and wants it back.

  11. SAR: Stroke Authorship Recognition

    KAUST Repository

    Shaheen, Sara

    2015-10-15

    Are simple strokes unique to the artist or designer who renders them? If so, can this idea be used to identify authorship or to classify artistic drawings? Also, could training methods be devised to develop particular styles? To answer these questions, we propose the Stroke Authorship Recognition (SAR) approach, a novel method that distinguishes the authorship of 2D digitized drawings. SAR converts a drawing into a histogram of stroke attributes that is discriminative of authorship. We provide extensive classification experiments on a large variety of data sets, which validate SAR\\'s ability to distinguish unique authorship of artists and designers. We also demonstrate the usefulness of SAR in several applications including the detection of fraudulent sketches, the training and monitoring of artists in learning a particular new style and the first quantitative way to measure the quality of automatic sketch synthesis tools. © 2015 The Eurographics Association and John Wiley & Sons Ltd.

Around 80 % of strokes are ischemic and different forms of intracranial bleeding account for the remaining cases. Monogenic stroke disorders are rare but the diagnosis may lead to specific therapeutic consequences for the affected patients who are predominantly young. In common sporadic stroke, genetic factors play a role in the form of susceptibility genes. Their discovery may give rise to new therapeutic options in the future.

    Hemorrhagic stroke accounts for approximately half of stroke in childhood. Unlike arterial ischemic stroke, there are no consensus guidelines to assist in the evaluation and treatment of these children. We review the literature on the evaluation, treatment, etiology and neurologic outcome of hemorrhagic stroke in children. Important differences between pediatric and adult hemorrhage are highlighted, as treatment guidelines for adults may not be applicable in all cases. Needed future research ...

    Following stroke, re-engagement in personally valued activities requires some experience of risk. Risk, therefore, must be seen as having positive as well as negative aspects in rehabilitation. Our aim was to identify the dominant understanding of risk in stroke rehabilitation and the assumptions underpinning these understandings, determine how these understandings affect research and practise, and if necessary, propose alternate ways to conceptualise risk in research and practise. Alvesson and Sandberg's method of problematisation was used. We began with a historical overview of stroke rehabilitation, and proceeded through five steps undertaken in an iterative fashion: literature search and selection; data extraction; syntheses across texts; identification of assumptions informing the literature and; generation of alternatives. Discussion of risk in stroke rehabilitation is largely implicit. However, two prominent conceptualisations of risk underpin both knowledge development and clinical practise: the risk to the individual stroke survivor of remaining dependent in activities of daily living and the risk that the health care system will be overwhelmed by the costs of providing stroke rehabilitation. Conceptualisation of risk in stroke rehabilitation, while implicit, drives both research and practise in ways that reinforce a focus on impairment and a generic, decontextualised approach to rehabilitation. Implications for rehabilitation Much of stroke rehabilitation practise and research seems to centre implicitly on two risks: risk to the patient of remaining dependent in ADL and risk to the health care system of bankruptcy due to the provision of stroke rehabilitation. The implicit focus on ADL dependence limits the ability of clinicians and researchers to address other goals supportive of a good life following stroke. The implicit focus on financial risk to the health care system may limit access to rehabilitation for people who have experienced either milder or

    Full Text Available Stroke is a huge public health problem because of its high morbidity and disability. The epidemiology of stroke is of relevance to construct practical paradigms to tackle this major health issue in the community. Recent data have shown that about 72-86% of strokes are ischemic, 9-18% are due to hemorrhage (intracerebral of subarachnoid and the rest are undefined. The risk factors for stroke are multiple and combined. At present, stroke is no more considered as unavoidable and untreatable. It is an emergency and specialized units and teams improve outcome and lower costs. Death related to stroke is declining in many countries and in both sexes. This decrease in multifactorial. The detection and more effective treatment of hypertension may play an important factor, as well as the improved medical care and improvement in diagnostic procedures. While stroke incidence appears stable and stroke mortality is slowly declining, the absolute magnitude of stroke is likely to grow over the next 30 years. as the population ages, the absolute number of stroke victims and demands on healthcare and other support systems is likely to increase substantially in the future. Keeping this in perspective, this chapter shall focus on the epidemiology of stroke in the world and in Indian, in particular.

    Full Text Available Circadian variations in conjunction with sleep-related heart rhythm changes and sleepdisordered breathing (SDB are contributing risk factors for stroke. Strong scientificevidence now exists indicating that SDB contributes to systemic hypertension, aprominent risk factor for stroke, and compelling circumstantial evidence is presentsuggesting that SDB raises the risk for development of stroke through other circulatorymechanisms as well. Preliminary evidence indicates that post-stroke patients have ahigher prevalence of SDB, which is likely to compromise their rehabilitation outcomes.Since SDB is modifiable with the application of CPAP and other treatment modalities,there is practical value in investigating patients at risk of stroke or post stroke forpresence of SDB. Successful application of CPAP or BiPAP therapy may improve theoutcome in both instances.Key words : Sleep, Stroke, SDB, CPAP

    Objective: To evaluate the baseline National Institute of Health Stroke Scale (NIHSS) score as a predictor of functional outcome after ischemic stroke. Subjects and Methods: The study included 50 patients who presented to Civil Hospital, Karachi, during the study period with acute stroke and were evaluated with CT scan of brain. Only those patients were enrolled in the study that had acute ischemic stroke. The enrolled subjects were then evaluated for the neurological impairment using National Institute of Health Stroke Scale (NIHSS). The subjects were followed-up and their functional outcome was assessed using Barthel index (BI) on the 7th day of their admission. Results: Of the fifty patients enrolled in the study, 31 (62%) were males and 19 (38%) were females, with age ranging from 45 years to 95 years and a mean age of 59.9 years. Neurological impairment at presentation was assessed by NIHSS. The score ranged between 2 and 28. The functional outcome was evaluated on the 7th day using Barthel index (BI), which ranged from 0 to 80. NIHSS score was found to be a good predictor of functional outcome in patients with ischemic stroke (p<0.001). Other factors like gender, hypertension and heart disease did not affect the functional recovery in such patients. Various factors were found to be significant for early prediction of stroke recovery. The NIHSS score was the strongest predictor of outcome after ischemic stroke. Age at the time of the event was also found to be an important predictor for stroke recovery. Conclusion: The NIHSS score is a good predictor of patient's recovery after stroke. Assessing the patient's neurological impairment at first presentation of ischemic stroke can guide the physician regarding the prognosis and management plan. (author)

    2012-01-01

    Full Text Available Background. Fatigue after stroke is common and distressing to patients. Aims. Our aims were to explore patients' perceptions of post-stroke fatigue, including the causes of fatigue and the factors that alleviate fatigue, in a mixed methods study. Results. We interviewed 15 patients who had had a stroke and were inpatients on stroke rehabilitation wards. A substantial proportion of patients reported that their fatigue started at the time of their stroke. Various different factors were reported to improve fatigue, including exercise, good sleep, rehabilitation and rest. Fatigue influences patients' sense of “control” after their stroke. Conclusion. Our results are consistent with the possibility that poststroke fatigue might be triggered by factors that occur at the time of the stroke (e.g., the stroke lesion itself, or admission to hospital and then exacerbated by poor sleep and boredom. These factors should be considered when developing complex interventions to improve post-stroke fatigue.

  1. Diagnosis in stroke - an uptake

    International Nuclear Information System (INIS)

    Aichner, F.T.

    2003-01-01

    In practical day-to-day terms, most patients have one of the common causes of stroke: ischemic stroke caused by the complications of atherothrombosis, intracranial small vessel disease, embolism from the heart, primary intracerebral hemorrhage caused by hypertension, or subarachnoid hemorrhage as a result of a ruptured saccular aneurysm. There are three issues to be considered in assessing the reliability of the clinical diagnosis of stroke: the diagnosis of stroke itself: is it a stroke or not; whether the stroke is caused by an infarct or a hemorrhage and particular in ischemic stroke the site and size of the lesion (anterior vs. posterior circulation, lacunar vs. cortical, etc.). No clinical scoring method can differentiate with absolute reliability ischemic stroke from primary intracerebral hemorrhage. To do this brain computed tomography or magnetic resonance imaging is required. For vascular diagnosis ultrasound and magnetic resonance angiography are ideal and complementary non-invasive techniques. Both have no risks and are reasonably sensitive. Catheterangiography is only reserved for patients with subarachnoid hemorrhage with a view to surgical or endovascular treatment or in exceptional cases to establish a more firm prognosis. The diagnosis of ischemic stroke caused by embolism from the heart can only be considered at all if there is an identifiable cardioembolic source which is the case in about 30 % of ischemic stroke, a higher proportion in recent studies using transoesophageal echocardiography. It is not clear that transoesophageal echocardiography provides much more information for clinical decision-making than transthoracic echocardiography, although it certainly provides more anatomical information in selected patients. This article summarizes the diagnostic armamentarium which is used for the diagnosis of stroke and gives an overview of clinically reliable and relevant measures. Refs. 23 (author)

    Stroke on board aircraft has been reported in retrospective case series, mainly focusing on economy class stroke syndrome. Data on the actual incidence, pathogenesis, and prognosis of stroke in commercial flights are lacking. A prospective registry was designed to include all consecutive patients referred from an international airport (40 million passengers a year) to our hospital with a diagnosis of ischemic stroke or transient ischemic attack and onset of symptoms during a flight or immediately after landing. Forty-four patients (32 ischemic strokes and 12 transient ischemic attacks) were included over a 76-month period (January 2008 to April 2014). The estimated incidence of stroke was 1 stroke in 35 000 flights. Pathogeneses of stroke or transient ischemic attack were atherothrombotic in 16 (36%), economy class stroke syndrome in 8 (18%), cardioembolic in 7 (16%), arterial dissection in 4 (9%), lacunar stroke in 4 (9%), and undetermined in 5 (12%) patients. Carotid stenosis >70% was found in 12 (27%) of the patients. Overall prognosis was good, and thrombolysis was applied in 44% of the cases. The most common reason for not treating patients who had experienced stroke onset midflight was the delay in reaching the hospital. Only 1 patient with symptom onset during the flight prompted a flight diversion. We found a low incidence of stroke in the setting of air travel. Economy class stroke syndrome and arterial dissection were well represented in our sample. However, the main pathogenesis was atherothrombosis with a high proportion of patients with high carotid stenosis. © 2016 American Heart Association, Inc.

    Full Text Available Introduction: stroke in recreational substance users can be an indirect complication, like endocarditis and cardio embolism in parenteral drug users. With some drug like cocaine, stroke appear to be the result of a direct effect. In young subjects without other risk factors provide persuasive evidence for causality . OPIATES: Heroine is the most abused opiate drug, which is administered by injection, by snorting or by smoking. Stroke affects heroin users by diverse mechanisms,. Injectors are at risk of infections endocarditis, which carries risk for both ischemic and hemorrhagic stroke. Cerebral or subarachnoid hemorrhage usually occurs after rupture of a septic (mycotic aneurysm. Heroine users can are also at risk for hemorrhagic stroke secondary to liver failure with deranged clotting and to heroin nephropathy with uremia or malignant hypertension. In some heroin users the drug it self is directly causal due to vasculitis, hypersensitivity and immunologic changes. Embolization of foreign material to brain due to mixed of heroine with quinine can cause cerebral embolism. AMPHETAMINE AND other psychostimulants: In abuser of amphetamine hemorrhagic stroke can occur, oral, intravenous, nasal, and inhalational routes of administration have been reported. Most were chronic user, but in several patients, stroke followed a first exposure. Some of amphetamine induced intracranial hemorrhages are secondary to acute hypertension, some to cerebral vacuities, and some to a combination of two. Decongestants and diet pills: Phenylpropanolamine (PPA, an amphetamine – like drug, in decongestants and diet pills, induce acute hypertension, sever headache, psychiatric symptoms, seizures and hemorrhagic stroke. Ephedrine and pseudo ephedrine are present in decongestants and bronchodilators and induce headache, tachyarrhythmia, hypertensive emergency, and hemorrhagic and occlusive stroke.

    Nurses often have difficulties with using interdisciplinary stroke guidelines for patients with stroke as they do not focus sufficiently on nursing. Therefore, the Stroke Nursing Guideline (SNG) was developed and implemented. The aim of this study was to determine the implementation and feasibility of the SNG in terms of changes in documentation and use of the guideline in the care of stroke patients on Neurological and Rehabilitation wards, barriers and facilitators, and nurses' and auxiliary nurses' view of the implementation. A sequential explorative mixed method design was used including pre-test post-test measures and post intervention focus groups interviews. For the quantitative part retrospective electronic record data of nursing care was collected from 78 patients and prospective measures with Barriers and Facilitators Assessment Instrument (BFAI) and Quality Indicator Tool (QIT) from 33 nursing staff including nurses and auxiliary nurses. In the qualitative part focus groups interviews were conducted with nursing staff on usefulness of the SNG and experiences with implementation. Improved nursing documentation was found for 23 items ( N  = 37), which was significant for nine items focusing mobility ( p  = 0.002, p  = 0.024, p  = 0.012), pain ( p  = 0.012), patient teaching ( p  = 0.001, p  = 0.000) and discharge planning ( p  = 0.000, p  = 0.002, p  = 0.004). Improved guideline use was found for 20 QIT-items ( N  = 30), with significant improvement on six items focusing on mobility ( p  = 0.023), depression ( p  = 0.033, p  = 0.025, p  = 0.046, p  = 0.046), discharge planning ( p  = 0.012). Facilitating characteristics for change were significantly less for two of four BFAI-subscales, namely Innovation ( p  = 0.019) and Context ( p  = 0.001), whereas no change was found for Professional and Patient subscales. The findings of the focus group interviews showed the SNG to be useful

    Full Text Available Hypertension is the most important modifiable risk factor for primary and secondary stroke prevention.All antihypertensive drugs are effective in primary prevention: the risk reduction for stroke is 30—42%. However, not all classes of drugs have the same effects: there is some indication that angiotensin receptor blockers may be superior to other classes of antihypertensive drugs in stroke prevention.Seventy-five percent of patients who present to hospital with acute stroke have elevated blood pressure within the first 24—48 hours. Extremes of systolic blood pressure (SBP increase the risk of death or dependency. The aim of treatment should be to achieve and maintain the SBP in the range 140—160 mmHg. However, fast and drastic blood pressure lowering can have adverse consequences.The PROGRESS trial of secondary prevention with perindopril + indapamide versus placebo + placebo showed a decrease in numbers of stroke recurrences in patients given both active antihypertensive agents, more impressive for cerebral haemorrhage.There were also indications that active treatment might decrease the development of post-stroke dementia.

    Stroke is a clinical syndrome of a rapidly developing focal neurological deficit that may be classified for practical purposes into ischaemic and haemorrhagic. The role of imaging is to exclude mimics of ischaemic stroke or intracranial haemorrhage and confirm the presence of an ischaemic stroke. Computed tomography (CT) remains the investigation of choice to exclude acute intracranial haemorrhage but diffusion weighted magnetic resonance (MR) has proved to be a sensitive method of detecting early ischaemic infarction. Perfusion weighted MR allows further assessment at the same examination that could help guide the clinician in the risk/benefit analysis of treatment with thrombolytics or neuroprotective agents under evaluation. This can also be achieved with CT. This review article discusses the imaging of ischaemic stroke, relating the pathophysiology of stroke to it. It deals separately in more detail with these newer MR techniques. Hoggard, N. et al. (2001)

    Full Text Available Objective The aim of this project was to complete an analysis of monograph and audiovisual items held in the Central Coast Health Service (CCHS Libraries and containing information relevant to the treatment of acute stroke. Acute stroke is treated by multidisciplinary teams of clinicians based at two hospitals within the CCHS. The adequacy of the library collection was measured by subject coverage and age. Methods The methodology used consisted of three main steps: a literature review; design, administration, and analysis of a questionnaire to members of the CCHS Acute Stroke Team; and an analysis of the libraries’ collections. The research project utilised project management methodology and an evidence based librarianship framework. Results The questionnaire revealed that electronic resources were by far the most frequently used by participants, followed in order by print journals, books, interlibrary loan articles, and audiovisual items. Collection analysis demonstrated that the monograph and audiovisual collections were adequate in both scope and currency to support the information needs of Acute Stroke Team members, with the exception of resources to support patient education. Conclusion The researchers developed recommendations for future collection development in the area of acute stroke resources. Conducting this project within the evidence based librarianship framework helped to develop library staff members’ confidence in their ability to make future collection development decisions, informed by the target group’s information needs and preferences. The collection analysis methodology was designed to be replicated, and new specialist groups within the client base of the library will be targeted to repeat the collection analysis process.

    The European Stroke Organisation (ESO) held its first European Stroke Science Workshop in Garmisch-Partenkirchen, Germany (15-17 December 2011). Stroke experts based in Europe were invited to present and discuss their current research. The scope of the workshop was to review the most recent findings of selected topics in stroke, to exchange ideas, to stimulate new research and to enhance collaboration between European stroke research groups. Seven scientific sessions were held, each starting with a keynote lecture to review the state of the art of the given topic, followed by 4 or 5 short presentations by experts. They were asked to limit their presentations to 10 slides containing only recent information. The meeting was organized by the executive committee of the ESO (Heinrich Mattle, chairman, Michael Brainin, Angel Chamorro, Werner Hacke, Didier Leys) and supported by the European Stroke Conference (Michael Hennerici).

    assess all potential post-stroke visual impairments. The current tools screen for only a number of potential stroke-related impairments, which means many visual defects may be missed. The sensitivity of those which screen for all impairments is significantly lowered when patients are unable to report their visual symptoms. Future research is required to develop a tool capable of assessing stroke patients which encompasses all potential visual deficits and can also be easily performed by both the patients and administered by health care professionals in order to ensure all stroke survivors with visual impairment are accurately identified and managed. Implications for Rehabilitation Over 65% of stroke survivors will suffer from a visual impairment, whereas 45% of stroke units do not assess vision. Visual impairment significantly reduces the quality of life, such as being unable to return to work, driving and depression. This review outlines the available screening methods to accurately identify stroke survivors with visual impairments. Identifying visual impairment after stroke can aid general rehabilitation and thus, improve the quality of life for these patients.

    Full Text Available Background: Stroke is a disease with a high mortality rate and common cause of disability. Nutritional factors are strongly associated with this disease. Malnutrition in hospitalized patients increases the incidence of complications, prolonged the length of stay and also the cost of hospitalization. Furthermore, nutritional status of stroke patients can deteriorate during hospitalization. The prevalence of malnutrition in hospitalized stroke patients is about 6% to 62%. The objective of this study was to identify  the nutritional status of hospitalized stroke patient. Methods: This was a descriptive cross-sectional study. Population of the study was hospitalized stroke patients at Neurology Ward, Kemuning Building Dr. Hasan Sadikin General Hospital Bandung, Indonesia from August until October 2014 who meet the inclusion criteria. Nutritional status was measured objectively using Body Mass Index (BMI and subjectively using Subjective Global Assessment (SGA method. The collected data were processed using  frequency tabulation and percentage. Results: Twenty six hospitalized stroke patients were included in this study. The hospitalized patients with normal BMI were about 12 people (46.15%, 8 people were overweight (30.77%, 4 people were undernourished (15.39% and 2 people (7.69% were obese. According to SGA measurement, approximately 18 people (69.22% were moderately malnourished, and as much as 4 people (15.39% were in good nutrition, whereas 4 people (15.39% were severely malnourished. Conclusions: Majority of the hospitalized stroke patients has normal BMI and moderately malnourished based on SGA.   DOI: 10.15850/amj.v4n2.1090

    2013-01-01

    Stroke is perceived a major cause of disability, including gait disorders. Looking for more effective methods of gait reeducation in post-stroke survivors is one of the most important issues in contemporary neurorehabilitation. Following a stroke, patients suffer from gait disorders. The aim of this paper is to present the outcomes of a study of post-stroke gait reeducation using the NeuroDevelopmental Treatment-Bobath (NDT-Bobath) method. The research was conducted among 60 adult patients who had undergone ischemic stroke. These patients were treated using the NDT-Bobath method. These patients' gait reeducation was assessed using spatio-temporal gait parameters (gait velocity, cadence and stride length). Measurements of these parameters were conducted by the same therapist twice: on admission, and after the tenth session of gait reeducation. Among the 60 patients involved in the study, the results were as follows: in terms of gait velocity, recovery was observed in 39 cases (65%), in terms of cadence, recovery was observed in 39 cases (65%), in terms of stride length, recovery was observed in 50 cases (83.33%). Benefits were observed after short-term therapy, reflected by measurable statistically significant changes in the patients' gait parameters.

    Inflammatory and immune responses in the brain can shape the clinical presentation and outcome of stroke. Approaches for effective management of acute stroke are sparse and many measures for brain protection fail, but our ability to modulate the immune system and modify the disease progression of multiple sclerosis is increasing. As a result, immune interventions are currently being explored as therapeutic interventions in acute stroke. In this Review, we compare the immunological features of acute stroke with those of multiple sclerosis, identify unique immunological features of stroke, and consider the evidence for immune interventions. In acute stroke, microglia activation and cell death products trigger an inflammatory cascade that damages vessels and the parenchyma within minutes to hours of the ischaemia or haemorrhage. Immune interventions that restrict brain inflammation, vascular permeability and tissue oedema must be administered rapidly to reduce acute immune-mediated destruction and to avoid subsequent immunosuppression. Preliminary results suggest that the use of drugs that modify disease in multiple sclerosis might accomplish these goals in ischaemic and haemorrhagic stroke. Further elucidation of the immune mechanisms involved in stroke is likely to lead to successful immune interventions. PMID:26303850

    Traditional Chinese patent medicines are widely used to treat stroke because it has good efficacy in the clinical environment. However, because of the lack of knowledge on traditional Chinese patent medicines, many Western physicians, who are accountable for the majority of clinical prescriptions for such medicine, are confused with the use of traditional Chinese patent medicines. Therefore, the aid-decision method is critical and necessary to help Western physicians rationally use traditional Chinese patent medicines. In this paper, Manifold Ranking is employed to develop the aid-decision model of traditional Chinese patent medicines for stroke treatment. First, 115 stroke patients from three hospitals are recruited in the cross-sectional survey. Simultaneously, traditional Chinese physicians determine the traditional Chinese patent medicines appropriate for each patient. Second, particular indicators are explored to characterize the population feature of traditional Chinese patent medicines for stroke treatment. Moreover, these particular indicators can be easily obtained byWestern physicians and are feasible for widespread clinical application in the future. Third, the aid-decision model of traditional Chinese patent medicines for stroke treatment is constructed based on Manifold Ranking. Experimental results reveal that traditional Chinese patent medicines can be differentiated. Moreover, the proposed model can obtain high accuracy of aid decision.

  8. Cognitive performance after ischaemic stroke

    Maria Gabriela R. Ferreira

    Full Text Available Cognitive impairment after stroke affects the patient recovery process. Therefore, the identification of factors associated with cognitive outcomes is important since it allows risk profiles of stroke survivors to be determined. OBJECTIVE: To assess cognitive outcome of stroke outpatients and investigate associations among clinical and demographic variables, vascular risk factors, depression symptoms and functional ability; and to describe the neuropsychological profile of these patients. METHODS: A cross-sectional design study was conducted. Subjects who suffered a first-ever ischaemic stroke 6 to 10 months prior to data collection underwent neuropsychological assessment and screening for depressive symptoms and functional ability. The outcome "cognitive performance" was analyzed considering two groups: "cognitive impairment" and "no cognitive impairment". RESULTS: There was a statistically significant association between cognitive impairment and female gender, age, stroke severity and functional ability. Regarding neuropsychological profile, the cognitive impairment group exhibited more generalized deficits in attention, visuospatial organization, verbal functions and verbal memory domains compared to the community control group. CONCLUSION: The occurrence of cognitive impairment among patients was high, especially in women, older participants, individuals with more severe stroke, and greater impairment in functional ability. Multiple cognitive domains are affected and this may hamper recovery and negatively impact independence and quality of life after stroke.

    Stroke is the third most common cause of death in the United States and is the number one cause of long-term disability. Legislative mandates, largely the result of the American Heart Association, American Stroke Association, and Brain Attack Coalition working cooperatively, have resulted in nationwide standardization of care for patients who experience a stroke. Transport to a skilled facility that can provide optimal care, including immediate treatment to halt or reverse the damage caused by stroke, must occur swiftly. Admission to a certified stroke center is recommended for improving outcomes. Most strokes are ischemic in nature. Acute ischemic stroke is a heterogeneous group of vascular diseases, which makes targeted treatment challenging. To provide a thorough review of the literature since the 2007 acute ischemic stroke guidelines were developed, we performed a search of the MEDLINE database (January 1, 2004-July 1, 2009) for relevant English-language studies. Results (through July 1, 2009) from clinical trials included in the Internet Stroke Center registry were also accessed. Results from several pivotal studies have contributed to our knowledge of stroke. Additional data support the efficacy and safety of intravenous alteplase, the standard of care for acute ischemic stroke since 1995. Due to these study results, the American Stroke Association changed its recommendation to extend the time window for administration of intravenous alteplase from within 3 hours to 4.5 hours of symptom onset; this recommendation enables many more patients to receive the drug. Other findings included clinically useful biomarkers, the role of inflammation and infection, an expanded role for placement of intracranial stents, a reduced role for urgent carotid endarterectomy, alternative treatments for large-vessel disease, identification of nontraditional risk factors, including risk factors for women, and newly published pediatric stroke guidelines. In addition, new devices for

    Stroke services have been centralised in several countries in recent years. Diagnosing acute stroke is challenging and a high proportion of patients admitted to stroke units are diagnosed as a non-stroke condition (stroke mimics). This study aims to describe the stroke mimic patient group, including their impact on stroke services. We analysed routine clinical data from 2,305 consecutive admissions to a stroke unit at St George's Hospital, London. Mimic groupings were derived from 335 individual codes into 17 groupings. From 2,305 admissions, 555 stroke mimic diagnoses were identified (24.2%) and 72% of stroke mimics had at least one stroke risk factor. Common mimic diagnoses were headache, seizure and syncope. Medically unexplained symptoms and decompensation of underlying conditions were also common. Median length of stay was 1 day; a diagnosis of dementia (p=0.028) or needing MRI (p=0.006) was associated with a longer stay. Despite emergency department assessment by specialist clinicians and computed tomography brain, one in four suspected stroke patients admitted to hospital had a non-stroke diagnosis. Stroke mimics represent a heterogeneous patient group with significant impacts on stroke services. Co-location of stroke and acute neurology services may offer advantages where service reorganisation is being considered. © Royal College of Physicians 2016. All rights reserved.

    2013-01-01

    Beyond the original meaning of chronic kidney disease (CKD) as high-risk state for future dialysis, CKD is now known as an established risk factor for cardiovascular diseases. Stroke is a major player of cardiovascular disease and has deep two-way relationships with CKD. CKD is an evident risk factor for stroke. Meta-analyses of cohort studies and trials indicate that proteinuria/albuminuria increases the risk of stroke by 71-92%, and reduced glomerular filtration rate increases the risk by 43%. In addition, CKD has a strong relationship with subclinical brain damage including white matter changes, microbleeds, cognitive impairment, and carotid atherosclerosis. CKD is prevalent in acute stroke patients; patients with estimated glomerular filtration rate stroke patients and 39% of total intracerebral hemorrhage patients in our institute. Acute and chronic management of stroke are influenced by CKD. Therapeutic effects of several antithrombotic and thrombolytic agents, including recently-developed novel oral anticoagulants, are affected by renal function. Moreover, reduced glomerular filtration rate is independently associated with increased 1- and 10-year mortalities in the end. Stroke also has deep relationships with end-stage kidney disease. Stroke occurs much more commonly in dialysis patients than general population or CKD patients without need for dialysis. The triggers of ischemic and hemorrhagic stroke in patients with end-stage kidney disease include special characteristics unique to dialysis, such as drastic hemodynamic change, dialysate and anticoagulants, and vascular calcification. As cohorts of dialysis patients become older, more hypertensive, and more diabetic than before, stroke become more prevalent and more serious events in dialysis clinics. Now, clinicians should have much interest in the association between CKD and cerebrovascular diseases, so-called the cerebro-renal interaction. Copyright © 2013 S. Karger AG, Basel.

    2012-01-31

    BACKGROUND: Robust international data support the effectiveness of stroke unit (SU) care. Despite this, most stroke care in Ireland are provided outside of this setting. Limited data currently exist on the quality of care provided. AIM: The aim of this study is to examine the quality of care for patients with stroke in two care settings-Regional General Hospital (RGH) and Stroke Rehabilitation Unit (SRU). METHODS: A retrospective analysis of the stroke records of consecutive patients admitted to the SRU between May-November 2002 and April-November 2004 was performed applying the UK National Sentinel Audit of Stroke (NSAS) tool. RESULTS: The results of the study reveal that while SRU processes of care was 74% compliant with standards; compliance with stroke service organisational standards was only 15 and 43% in the RGH and SRU, respectively. CONCLUSION: The quality of stroke care in our area is deficient. Comprehensive reorganisation of stroke services is imperative.

    Full Text Available Background: Since the emergency department (ED waiting room hosts a large, captive audience of patients and visitors, it may be an ideal location for conduct-ing focused stroke education. The aim of this study was to assess the effective-ness of various stroke education methods.Methods: Patients and visitors of an urban ED waiting room were randomized into one of the following groups: video, brochure, one-to-one teaching, combi-nation of these three methods, or control group. We administered a 13-question multiple-choice test to assess stroke knowledge prior to, immediately after, and at 1 month post-education to patients and visitors in the ED waiting room.Results: Of 4 groups receiving education, all significantly improved their test scores immediately post intervention (test scores 9.4±2.5-10.3±2.0, P<0.01. At 1 month, the combination group retained the most knowledge (9.4±2.4 exceed-ing pre-intervention and control scores (both 6.7±2.6, P<0.01.Conclusion: Among the various stroke education methods delivered in the ED waiting room, the combination method resulted in the highest knowledge reten-tion at 1-month post intervention.

  17. Dizziness in stroke

    Directory of Open Access Journals (Sweden)

    M. V. Zamergrad

    2015-01-01

    Full Text Available Differential diagnosis of new-onset acute vestibular vertigo is chiefly made between vestibular neuronitis and stroke. Dizziness in stroke is usually accompanied by other focal neurological symptoms of brainstem and cerebellar involvement. However, stroke may appear as isolated vestibular vertigo in some cases. An analysis of history data and the results of neurovestibular examination and brain magnetic resonance imaging allows stroke to be diagnosed in patients with acute isolated dizziness. The treatment of patients with stroke-induced dizziness involves a wide range of medications for the reduction of the degree of dizziness and unsteadiness and for the secondary prevention of stroke. Vestibular rehabilitation is an important component of treatment. The paper describes an observation of a patient with poorly controlled hypertension, who developed new-onset acute systemic dizziness. Vestibular neuronitis might be presumed to be a peripheral cause of vestibular disorders, by taking into account the absence of additional obvious neurological symptoms (such as pareses, defective sensation, diplopia, etc. and the nature of nystagmus. However, intention tremor in fingernose and heel-knee tests on the left side, a negative Halmagyi test, and results of Romberg’s test could suggest that stroke was a cause ofdizziness.

    2015-07-01

    Full Text Available In clinical settings, traditional stroke rehabilitation evaluation methods are subjectively scored by occupational therapists, and the assessment results vary individually. To address this issue, this study aims to develop a stroke rehabilitation assessment system by using inertial measurement units. The inertial signals from the upper extremities were acquired, from which three quantitative indicators were extracted to reflect rehabilitation performance during stroke patients’ movement examination, i.e., shoulder flexion. Both healthy adults and stroke patients were recruited to correlate the proposed quantitative evaluation indices and traditional rehab assessment scales. Especially, as a unique feature of the study the weight for each of three evaluation indicators was estimated by the least squares method. The quantitative results demonstrate the proposed method accurately reflects patients’ recovery from pre-rehabilitation, and confirm the feasibility of applying inertial signals to evaluate rehab performance through feature extraction. The implemented assessment scheme appears to have the potential to overcome some shortcomings of traditional assessment methods and indicates rehab performance correctly.

    Understanding the genetic architecture of cerebrovascular disease holds promise of novel stroke prevention strategies and therapeutics that are both safe and effective. Apart from a few single-gene disorders associated with cerebral ischemia or intracerebral hemorrhage, stroke is a complex genetic phenotype that requires careful ascertainment and robust association testing for discovery and validation analyses. The recently uncovered shared genetic contribution between clinically manifest stroke syndromes and closely related intermediate cerebrovascular phenotypes offers effective and efficient approaches to complex trait analysis.

    Assessing both stroke patients and their CT scans by using a conventional videoconference system offers an interesting opportunity to improve stroke care in rural areas. However, until now there have been no studies to suggest whether this method is feasible in routine stroke management. Seven rural hospitals in the southern part of Germany in Swabia were connected to the stroke unit of Günzburg with the use of a videoconference link (Telemedicine in Stroke in Swabia [TESS] Project). The local physicians are free to present every admitted stroke patient to the Günzburg stroke expert, who can assess the clinical status and CT images, thereafter giving therapeutic recommendations. All teleconsultations are rated concerning transmission quality and relevance of telemedicine for stroke management. A total of 153 stroke patients were examined by teleconsultation. Mean age was 67.5 years. Eighty-seven patients had suffered an ischemic stroke, 9 had an intracerebral hemorrhage, and 17 suffered a transient ischemic attack. Forty patients were revealed to have a diagnosis other than stroke. Duration of teleconsultation was 15 minutes on average. User satisfaction was good concerning imaging and audio quality, and patient satisfaction was very good or good in all cases. Relevant contributions could be made in >75% of the cases concerning diagnostic workup, CT assessment, and therapeutic recommendations. Teleconsultation using a videoconference system seems to be a feasible and promising method to improve stroke care in rural areas where management in a stroke unit is hindered by long transportation distances.

  7. Aphasia As a Predictor of Stroke Outcome.

    Science.gov (United States)

    Lazar, Ronald M; Boehme, Amelia K

    2017-09-19

    Aphasia is a common feature of stroke, affecting 21-38% of acute stroke patients and an estimated 1 million stroke survivors. Although stroke, as a syndrome, is the leading cause of disability in the USA, less is known about the independent impact of aphasia on stroke outcomes. During the acute stroke period, aphasia has been found to increase length of stay, inpatient complications, overall neurological disability, mortality, and to alter discharge disposition. Outcomes during the sub-acute and chronic stroke periods show that aphasia is associated with lower Functional Independence Measures (FIM) scores, longer stays in rehabilitation settings, poorer function in activities of daily living, and mortality. Factors that complicate the analysis of aphasia on post-stroke outcomes, however, include widely different systems of care across international settings that result in varying admission patterns to acute stroke units, allowable length of stays based on reimbursement, and criteria for rehabilitation placement. Aphasia arising from stroke is associated with worse outcomes both in the acute and chronic periods. Future research will have to incorporate disparate patterns in analytic models, and to take into account specific aphasia profiles and evolving methods of post-stroke speech-language therapy.

  8. Cortical swallowing processing in early subacute stroke

    2011-03-01

    Full Text Available Abstract Background Dysphagia is a major complication in hemispheric as well as brainstem stroke patients causing aspiration pneumonia and increased mortality. Little is known about the recovery from dysphagia after stroke. The aim of the present study was to determine the different patterns of cortical swallowing processing in patients with hemispheric and brainstem stroke with and without dysphagia in the early subacute phase. Methods We measured brain activity by mean of whole-head MEG in 37 patients with different stroke localisation 8.2 +/- 4.8 days after stroke to study changes in cortical activation during self-paced swallowing. An age matched group of healthy subjects served as controls. Data were analyzed by means of synthetic aperture magnetometry and group analyses were performed using a permutation test. Results Our results demonstrate strong bilateral reduction of cortical swallowing activation in dysphagic patients with hemispheric stroke. In hemispheric stroke without dysphagia, bilateral activation was found. In the small group of patients with brainstem stroke we observed a reduction of cortical activation and a right hemispheric lateralization. Conclusion Bulbar central pattern generators coordinate the pharyngeal swallowing phase. The observed right hemispheric lateralization in brainstem stroke can therefore be interpreted as acute cortical compensation of subcortically caused dysphagia. The reduction of activation in brainstem stroke patients and dysphagic patients with cortical stroke could be explained in terms of diaschisis.

    Objectives: To assess whether black race and other cerebrovascular risk factors have a differential effect on first vs recurrent stroke events. Methods: Estimate the differences in the magnitude of the association of demographic (age, back race, sex) or stroke risk factors (hypertension, diabetes, cigarette smoking, atrial fibrillation, left ventricular hypertrophy, or heart disease) for first vs recurrent stroke from a longitudinal cohort study of 29,682 black or white participants aged 45 years and older. Results: Over an average 6.8 years follow-up, 301 of 2,993 participants with a previous stroke at baseline had a recurrent stroke, while 818 of 26,689 participants who were stroke-free at baseline had a first stroke. Among those stroke-free at baseline, there was an age-by-race interaction (p = 0.0002), with a first stroke risk 2.70 (95% confidence interval: 1.86–3.91) times greater for black than white participants at age 45, but no racial disparity at age 85 (hazard ratio = 0.91; 95% confidence interval: 0.70–1.18). In contrast, there was no evidence of a higher risk of recurrent stroke at any age for black participants (p > 0.05). The association of traditional stroke risk factors was generally similar for first and recurrent stroke. Conclusion: The association of age and black race differs substantially on first vs recurrent stroke risk, with risk factors playing a similar role. PMID:26791153

    Ischaemic stroke is responsible for 80-85% of strokes. There is great interest in finding effective methods of rehabilitation for post-stroke patients. The aim of this study was to assess the results of rehabilitation carried out in the normalization of upper limb muscle tonus in patients, estimated on the Ashworth Scale for Grading Spasticity. The examined group consisted of 60 patients after ischaemic stroke. 10 sessions of NDT-Bobath therapy were provided within 2 weeks (ten days of therapy). Patient examinations using the Ashworth Scale for Grading Spasticity were done twice: the first time on admission and the second after the last session of the therapy to assess rehabilitation effects. Among the patients involved in the study, the results measured on the Ashworth Scale (where possible) were as follows: recovery in 16 cases (26.67%), relapse in 1 case (1.67%), no measurable changes (or change within the same grade of the scale) in 8 cases (13.33%). Statistically significant changes were observed in the health status of the patients. These changes, in the area of muscle tone, were favorable and reflected in the outcomes of the assessment using the Ashworth Scale for Grading Spasticity.

    Stroke is a high-frequency disorder placing a significant burden on the health care systems, being the foremost cause of complex chronic disability in adults. Devising systems that can enhance the prevention of stroke recurrence is an important priority and challenge in both the developed and the developing world. The potential for recurrent stroke can be substantially reduced by effective management of vascular risk factors. Telestroke is a tool with potential application to improve risk management of stroke survivors. Lack of acknowledgment of existing practices as well as lack of awareness of potential financial barriers to diffusion of telestroke can lead to limited implementation. Telestroke offers service providers the opportunity to access large numbers of stroke survivors targeting secondary prevention. The ideal 'telestroke model' provides service support, education for the patient and caregiver, as well as integration of specialist and primary care services. Effective use of technological advances, with adequate recognition of the importance of human interaction in the long-term management of a largely elderly population of stroke survivors is challenging but possible. Telestroke should be systems- and not technology-driven. Barriers in the implementation of telestroke have been identified as insufficient planning of IT infrastructure, lack of long-term vision for sustainability, a lack of contextual perspective as well as poor communication across domains. Future telestroke models should provide effective action in an integrated model of care recognizing and involving all existing players and practices. (c) 2009 S. Karger AG, Basel.

  17. Autopsy approach to stroke.

    Stroke is a major cause of morbidity and mortality but the brain and other relevant tissues are often examined only cursorily when stroke patients come to autopsy. The pathological findings and clinical implications vary according to the type of stroke and its location and cause. Large ischaemic strokes are usually associated with atherosclerosis of extracranial or major intracranial arteries but can be caused by dissection. Most small cerebral infarcts are caused by arteriosclerosis or, in the elderly, cerebral amyloid angiopathy (CAA). However, vasculitides and coagulopathies can cause a range of different patterns of ischaemic (and, occasionally, haemorrhagic) stroke. Global brain ischaemia, caused by severe hypotension or raised intracranial pressure, produces damage that is accentuated in certain regions and neuronal populations and may be confused with hypoglycaemic injury. The main cause of subarachnoid haemorrhage is a ruptured berry aneurysm but CAA, arteriovenous malformations and infective aneurysms are occasionally responsible. These can also cause parenchymal brain haemorrhage, although this most often complicates hypertensive small vessel disease. Sometimes the haemorrhage arises from a neoplasm. Performing an adequate autopsy in stroke requires proper preparation, awareness of the likely pathological processes, familiarity with intracranial vascular anatomy, careful gross examination and dissection, and appropriate use of histology. © 2010 Blackwell Publishing Limited.

    Full Text Available Mohammad Obadah Nakawah, Eugene C Lai Stanely H. Appel Department of Neurology, Houston Methodist Neurological Institute, Houston, TX, USA Abstract: Strokes, whether ischemic or hemorrhagic, are among the most common causes of secondary movement disorders in elderly patients. Stroke-related (vascular movement disorders, however, are uncommon complications of this relatively common disease. The spectrum of post-stroke movement disorders is broad and includes both hypo- and hyperkinetic syndromes. Post-stroke dyskinesias are involuntary hyperkinetic movements arising from cerebrovascular insults and often present with mixed phenotypes of hyperkinesia which can sometimes be difficult to classify. Nevertheless, identification of the most relevant motor phenotype, whenever possible, allows for a more specific phenomenological categorization of the dyskinesia and thus helps guide its treatment. Fortunately, post-stroke dyskinesias are usually self-limiting and resolve within 6 to 12 months of onset, but a short-term pharmacotherapy might sometimes be required for symptom control. Functional neurosurgical interventions targeting the motor thalamus or globus pallidus interna might be considered for patients with severe, disabling, and persistent dyskinesias (arbitrarily defined as duration longer than 12 months.

    Full Text Available Background Individuals with stroke often have multiple cardiovascular risk factors that necessitate promoting engagement in multiple health behaviors. However, observational studies of individuals with stroke have typically focused on promoting a single health behavior. Thus, there is a poor understanding of linkages between healthy behaviors and the circumstances in which factors, such as stroke impairments, may influence a single or multiple health behaviors. Methods We conducted a mixed methods convergent parallel study of 25 individuals with stroke to examine the relationships between stroke impairments and physical activity, sleep, and nutrition. Our goal was to gain further insight into possible strategies to promote multiple health behaviors among individuals with stroke. This study focused on physical activity, sleep, and nutrition because of their importance in achieving energy balance, maintaining a healthy weight, and reducing cardiovascular risks. Qualitative and quantitative data were collected concurrently, with the former being prioritized over the latter. Qualitative data was prioritized in order to develop a conceptual model of engagement in multiple health behaviors among individuals with stroke. Qualitative and quantitative data were analyzed independently and then were integrated during the inference stage to develop meta-inferences. The 25 individuals with stroke completed closed-ended questionnaires on healthy behaviors and physical function. They also participated in face-to-face focus groups and one-to-one phone interviews. Results We found statistically significant and moderate correlations between hand function and healthy eating habits (r = 0.45, sleep disturbances and limitations in activities of daily living (r =  − 0.55, BMI and limitations in activities of daily living (r =  − 0.49, physical activity and limitations in activities of daily living (r = 0.41, mobility impairments and BMI (r

  1. Improving public education about stroke.

    2012-09-01

    Stroke is a common and serious disease. Most studies have shown that basic public knowledge about what a stroke is, symptoms of a stroke, and the proper reaction to a stroke is quite deficient. The fact that a stroke affects cognitive, communicative, and motor functions may partially explain the poor reaction to acute stroke symptoms. Several educational studies, using diverse formats and messaging paradigms, have been shown to positively affect public knowledge of stroke symptoms. Such efforts have often used mass media public education campaigns with an emphasis on recognizing symptoms of an acute stroke. Some have been able to demonstrate an increase in the chance of patients (or by-standers) calling 911 and seeking emergency care. However, many programs were of brief duration, and their long-term benefits are uncertain. Continual educational efforts will be needed to improve stroke knowledge and increase the percentage of patients who seek emergency care. © 2012 New York Academy of Sciences.

Diabetes mellitus (DM is a state of accelerated aging of blood vessels. Patients with diabetes have increased risk of stroke. Hyperglycemia represents a risk factor for poor outcome following stroke, and probably is just a marker of poor outcome rather than a cause. Lowering of blood glucose levels has not been shown to improve prognosis. Also, prevention of stroke risk among patients with DM is not improved with therapy for reduction of glucose levels. On the other hand, prediabetes, a metabolic state between normal glucose metabolism and diabetes, is a risk factor for the development of DM type 2 and subsequently for stroke. Several methods are known to identify prediabetes patients, including fasting plasma glucose levels, 2-hour post load glucose levels, and glycosylated hemoglobin levels. In this text, we tried to summarize known data about diagnosis, epidemiology, risk factors, pathophysiology, and prevention of prediabetes in relation to DM and stroke.

    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.

    Low thrombolysis rates for acute ischemic stroke are linked to delays in seeking immediate treatment due to low public stroke awareness. We aimed to assess whether "Child-Mediated Stroke Communication" could improve stroke literacy of parents of children enrolled in a school-based stroke literacy program called Hip Hop Stroke. Parents of children aged 9 to 12 years from 2 public schools in Harlem, New York City, were recruited to participate in stroke literacy questionnaires before and after their child's participation in Hip Hop Stroke, a novel Child-Mediated Stroke Communication intervention delivered in school auditoriums. Parental recall of stroke information communicated through their child was assessed 1-week after the intervention. Fifth and sixth grade students (n=182) were enrolled into Hip Hop Stroke. One hundred two parents were approached in person to participate; 75 opted to participate and 71 completed both the pretest and post-test (74% response rate and 95% retention rate). Parental stroke literacy improved after the program; before the program, 3 parents of 75 (3.9%) were able to identify the 5 cardinal stroke symptoms, distracting symptom (chest pains), and had an urgent action plan (calling 911) compared with 21 of 71 parents (29.6%) postintervention (P<0.001). The FAST mnemonic was known by 2 (2.7%) of participants before the program versus 29 (41%) after program completion (P<0.001). Knowledge of stroke signs and symptoms remains low among residents of this high-risk population. The use of Child-Mediated Stroke Communication suggests that school children aged 9 to 12 years may be effective conduits of critical stroke knowledge to their parents.

    Longitudinal brain volume changes have been investigated in a number of cerebral disorders as a surrogate marker of clinical outcome. In stroke, unique methodological challenges are posed by dynamic structural changes occurring after onset, particularly those relating to the infarct lesion. We aimed to evaluate agreement between different analysis methods for the measurement of post-stroke brain volume change, and to explore technical challenges inherent to these methods. Fifteen patients with anterior circulation stroke underwent magnetic resonance imaging within 1 week of onset and at 1 and 3 months. Whole-brain as well as grey- and white-matter volume were estimated separately using both an intensity-based and a surface watershed-based algorithm. In the case of the intensity-based algorithm, the analysis was also performed with and without exclusion of the infarct lesion. Due to the effects of peri-infarct edema at the baseline scan, longitudinal volume change was measured as percentage change between the 1 and 3-month scans. Intra-class and concordance correlation coefficients were used to assess agreement between the different analysis methods. Reduced major axis regression was used to inspect the nature of bias between measurements. Overall agreement between methods was modest with strong disagreement between some techniques. Measurements were variably impacted by procedures performed to account for infarct lesions. Improvements in volumetric methods and consensus between methodologies employed in different studies are necessary in order to increase the validity of conclusions derived from post-stroke cerebral volumetric studies. Readers should be aware of the potential impact of different methods on study conclusions. (orig.)

    Background: Computed Tomography (CT) scan without contrast is the modality of choice for diagnosis of stroke. However, routine brain CT scan, with linear processing has some limitations in early diagnosis of ischemic stroke. The aim of this study was to evaluate and compare the sensitivity and specificity of processed CT images with conventional ones in early diagnosis of cerebrovascular attack (CVA). Patients and Methods: This was a self-controlled study conducted in a university referal hospital from 2010 to 2011. Seventy CT scans underwent a process using Laplacian Pyramid transform. Thirty five of participants were diagnosed with CVA while others had only headache and no ischemic stroke diagnosis based on the first and follow-up CT scans. A neuroradiologist made diagnosis with and without the help of processed CT scans. The McNemar and Wilcoxon analysis were used to compare the sensitivity, specificity, positive and negative predictive values of two methods. Results: The sensitivity (% 65.7 vs. %31.4, P value = 0.001), positive predictive value (% 85.2 vs. % 61, P value = 0.03) and negative predictive value (% 73.9% vs. %49, P value = 0.01) of the processed method were significantly higher than the routine one, while no difference was seen in specificity (% 88.6 vs. %77.1, P value = 0.15). Moreover, the accuracy of the processed method was significantly better than the linear one (P value Pyramid method can composed CT scans which can be more helpful in early detection of ischemic stroke.

    Stroke is a personal, familial, and social disaster. It is the third cause of death worldwide, the first cause of acquired disability, the second cause of dementia, and its cost is astronomic. The burden of stroke is likely to increase given the aging of the population and the growing incidence of many vascular risk factors. Prevention of stroke includes--as for all other diseases--a "mass approach" aiming at decreasing the risk at the society level and an individual approach, aiming at reducing the risk in a given subject. The mass approach is primarily based on the identification and treatment of vascular risk factors and, if possible, in the implementation of protective factors. These measures are the basis of primary prevention but most of them have now been shown to be also effective in secondary prevention. The individual approach combines a vascular risk factor modification and various treatments addressing the specific subtypes of stroke, such as antiplatelet drugs for the prevention of cerebral infarction in large and small artery diseases of the brain, carotid endarterectomy or stenting for tight carotid artery stenosis, and oral anticoagulants for the prevention of cardiac emboli. There is a growing awareness of the huge evidence-to-practice gap that exists in stroke prevention largely due to socio-economic factors. Recent approaches include low cost intervention packages to reduce blood pressure and cheap "polypills" combining in a single tablet aspirin and several drugs to lower blood pressure and cholesterol. Polypill intake should however not lead to abandon the healthy life-style measures which remain the mainstay of stroke prevention.

  1. Temporal profile of body temperature in acute ischemic stroke: relation to stroke severity and outcome

    2012-01-01

    Background Pyrexia after stroke (temperature ≥37.5°C) is associated with poor prognosis, but information on timing of body temperature changes and relationship to stroke severity and subtypes varies. Methods We recruited patients with acute ischemic stroke, measured stroke severity, stroke subtype and recorded four-hourly tympanic (body) temperature readings from admission to 120 hours after stroke. We sought causes of pyrexia and measured functional outcome at 90 days. We systematically summarised all relevant previous studies. Results Amongst 44 patients (21 males, mean age 72 years SD 11) with median National Institute of Health Stroke Score (NIHSS) 7 (range 0–28), 14 had total anterior circulation strokes (TACS). On admission all patients, both TACS and non-TACS, were normothermic (median 36.3°C vs 36.5°C, p=0.382 respectively) at median 4 hours (interquartile range, IQR, 2–8) after stroke; admission temperature and NIHSS were not associated (r2=0.0, p=0.353). Peak temperature, occurring at 35.5 (IQR 19.0 to 53.8) hours after stroke, was higher in TACS (37.7°C) than non-TACS (37.1°C, ptemperatures. Sixteen (36%) patients became pyrexial, in seven (44%) of whom we found no cause other than the stroke. Conclusions Normothermia is usual within the first 4 hours of stroke. Peak temperature occurs at 1.5 to 2 days after stroke, and is related to stroke severity/subtype and more closely associated with poor outcome than admission temperature. Temperature-outcome associations after stroke are complex, but normothermia on admission should not preclude randomisation of patients into trials of therapeutic hypothermia. PMID:23075282

    Fabricius, Charlotte; Petersen, Anders; Iversen, Helle K

    Objective: Impaired visual attention is common following strokes in the territory of the middle cerebral artery, particularly in the right hemisphere. However, attentional effects of more posterior lesions are less clear. The aim of this study was to characterize visual processing speed...... and apprehension span following posterior cerebral artery (PCA) stroke. We also relate these attentional parameters to visual word recognition, as previous studies have suggested that reduced visual speed and span may explain pure alexia. Methods: Nine patients with MR-verified focal lesions in the PCA......-territory (four left PCA; four right PCA; one bilateral, all >1 year post stroke) were compared to 25 controls using single case statistics. Visual attention was characterized by a whole report paradigm allowing for hemifield-specific speed and span measurements. We also characterized visual field defects...

    Full Text Available The brain has a large capacity for automatic simultaneous processing and integration of sensory information. Combining information from different sensory modalities facilitates our ability to detect, discriminate, and recognize sensory stimuli, and learning is often optimal in a multisensory environment. Currently used multisensory stimulation methods in stroke rehabilitation include motor imagery, action observation, training with a mirror or in a virtual environment, or various kinds of music therapy. Several studies have shown positive effects been reported but to give general recommendation more studies are needed. Patient heterogeneity and the interactions of age, gender, genes and environment are discussed. Randomized controlled longitudinal trials starting earlier post stroke are needed. The advance in brain network science and neuroimaging enabling longitudinal studies of structural and functional networks are likely to have an important impact on patient selection for specific interventions in future stroke rehabilitation.

    Purpose To use a mixed method design to evaluate how clinicians judge falls in stroke patients as a beneficial event, and to identify patient-specific characteristics associated with beneficial falls. Methods The definition of beneficial falls was based on interviews with six experienced clinicians in stroke rehabilitation. Interview data were analyzed using the grounded theory approach, with outcomes used to develop a checklist to judge falls as beneficial. We subsequently used the checklist to identify falls sustained by patients in our rehabilitation unit as beneficial events. The characteristics of beneficial fallers were investigated in this retrospective study. Results According to experienced clinicians, beneficial falls result from patient-specific factors and level of independence. Beneficial falls are not associated with after-effects or a diagnosis of cognitive impairment, do not result in physical injury and post-fall syndrome, and do not alter the course of rehabilitation. These falls are considered to enhance patients' self-awareness of their physical status and abilities. Among the 123 stroke patients who experienced a fall in our study group, 23 patients (18.7%) were identified as beneficial fallers according to our checklist. The majority had a left hemiplegia and perceptual impairments, and were at low risk of recurrent falls and made functional gains during rehabilitation. Conclusions Based on our results, we created a 10-item checklist to differentiate beneficial from adverse falls. This differentiation is important to target fall prevention programs to adverse fallers in rehabilitation units.

  6. Multimodal pressure-flow method to assess dynamics of cerebral autoregulation in stroke and hypertension

    2004-10-01

    Full Text Available Abstract Background This study evaluated the effects of stroke on regulation of cerebral blood flow in response to fluctuations in systemic blood pressure (BP. The autoregulatory dynamics are difficult to assess because of the nonstationarity and nonlinearity of the component signals. Methods We studied 15 normotensive, 20 hypertensive and 15 minor stroke subjects (48.0 ± 1.3 years. BP and blood flow velocities (BFV from middle cerebral arteries (MCA were measured during the Valsalva maneuver (VM using transcranial Doppler ultrasound. Results A new technique, multimodal pressure-flow analysis (MMPF, was implemented to analyze these short, nonstationary signals. MMPF analysis decomposes complex BP and BFV signals into multiple empirical modes, representing their instantaneous frequency-amplitude modulation. The empirical mode corresponding to the VM BP profile was used to construct the continuous phase diagram and to identify the minimum and maximum values from the residual BP (BPR and BFV (BFVR signals. The BP-BFV phase shift was calculated as the difference between the phase corresponding to the BPR and BFVR minimum (maximum values. BP-BFV phase shifts were significantly different between groups. In the normotensive group, the BFVR minimum and maximum preceded the BPR minimum and maximum, respectively, leading to large positive values of BP-BFV shifts. Conclusion In the stroke and hypertensive groups, the resulting BP-BFV phase shift was significantly smaller compared to the normotensive group. A standard autoregulation index did not differentiate the groups. The MMPF method enables evaluation of autoregulatory dynamics based on instantaneous BP-BFV phase analysis. Regulation of BP-BFV dynamics is altered with hypertension and after stroke, rendering blood flow dependent on blood pressure.

    2014-04-01

    Religious faith is central to life for Muslim patients in Kuwait, so it may influence adaptation and rehabilitation. This study explored quantitative associations among religious faith, self-efficacy, and life satisfaction in 40 female stroke patients and explored the influence of religion within stroke rehabilitation through qualitative interviews with 12 health professionals. The quantitative measure of religious faith did not relate to life satisfaction or self-efficacy in stroke patients. However, the health professionals described religious coping as influencing adaptation post-stroke. Fatalistic beliefs were thought to have mixed influences on rehabilitation. Measuring religious faith among Muslims through a standardized scale is debated. The qualitative accounts suggest that religious beliefs need to be acknowledged in stroke rehabilitation in Kuwait.

    Bernadette T Gillick

    2014-09-01

    Full Text Available Background- Transcranial direct current stimulation (tDCS has been investigated mainly in adults and doses may not be appropriate in pediatric applications. In perinatal stroke where potential applications are promising, rational adaptation of dosage for children remains under investigation.Objective - Construct child-specific tDCS dosing parameters through case study within a perinatal stroke tDCS safety and feasibility trial. Methods- 10-year-old subject with a diagnosis of presumed perinatal ischemic stroke and hemiparesis was identified. T1 MRI scans used to derive computerized model for current flow and electrode positions. Workflow using modeling results and consideration of dosage in previous clinical trials was incorporated. Prior Ad hoc adult montages versus de novo optimized montages provided distinct risk benefit analysis. Approximating adult dose required consideration of changes in both peak brain current flow and distribution which further tradeoff between maximizing efficacy and adding safety factors. Electrode size, position, current intensity, compliance voltage, and duration were controlled independently in this process.Results- Brain electric fields modeled and compared to values previously predicted models. Approximating conservative brain current flow patterns and intensities used in previous adult trials for comparable indications, the optimal current intensity established was 0.7 mA for 10 minutes with a tDCS C3/C4 montage. Specifically 0.7 mA produced comparable peak brain current intensity of an average adult receiving 1.0 mA. Electrode size of 5x7 cm2 with 1.0 mA and low-voltage tDCS was employed to maximize tolerability. Safety and feasibility confirmed with subject tolerating the session well and no serious adverse events.Conclusion- Rational approaches to dose customization, with steps informed by computational modeling, may improve guidance for pediatric stroke tDCS trials.

    The Comprehensive Post-Acute Stroke Services (COMPASS) Study is one of the first large pragmatic randomized-controlled clinical trials using comparative effectiveness research methods, funded by the Patient-Centered Outcomes Research Institute. In the COMPASS Study, we compare the effectiveness of a patient-centered, transitional care intervention versus usual care for stroke patients discharged home from acute care. Outcomes include stroke patient post-discharge functional status and caregiver strain 90 days after discharge, and hospital readmissions. A central tenet of Patient-Centered Outcomes Research Institute-funded research is stakeholder engagement throughout the research process. However, evidence on how to successfully implement a pragmatic trial that changes systems of care in combination with robust stakeholder engagement is limited. This combination is not without challenges. We present our approach for broad-based stakeholder engagement in the context of a pragmatic trial with the participation of patients, caregivers, community stakeholders, including the North Carolina Stroke Care Collaborative hospital network, and policy makers. To maximize stakeholder engagement throughout the COMPASS Study, we employed a conceptual model with the following components: (1) Patient and Other Stakeholder Identification and Selection; (2) Patient and Other Stakeholder Involvement Across the Spectrum of Research Activities; (3) Dedicated Resources for Patient and Other Stakeholder Involvement; (4) Support for Patient and Other Stakeholder Engagement Through Organizational Processes; (5) Communication with Patients and Other Stakeholders; (6) Transparent Involvement Processes; (7) Tracking of Engagement; and (8) Evaluation of Engagement. In this paper, we describe how each component of the model is being implemented and how this approach addresses existing gaps in the literature on strategies for engaging stakeholders in meaningful and useful ways when conducting

When acupuncture was compared with sham acupuncture, findings for adverse events were uncertain (OR 0.58, 95% CI 0.29 to 1.16; five trials with 576 participants; low-quality evidence). This updated review indicates that apparently improved outcomes with acupuncture in acute stroke are confounded by the risk of bias related to use of open controls. Adverse events related to acupuncture were reported to be minor and usually did not result in stopping treatment. Future studies are needed to confirm or refute any effects of acupuncture in acute stroke. Trials should clearly report the method of randomization, concealment of allocation, and whether blinding of participants, personnel, and outcome assessors was achieved, while paying close attention to the effects of acupuncture on long-term functional outcomes.

    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 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.

  19. Experimental Evaluation of a Method for Turbocharging Four-Stroke, Single Cylinder, Internal Combustion Engines

    Buchman, Michael; Winter, Amos

    2015-11-01

    Turbocharging an engine increases specific power, improves fuel economy, reduces emissions, and lowers cost compared to a naturally aspirated engine of the same power output. These advantages make turbocharging commonplace for multi-cylinder engines. Single cylinder engineers are not commonly turbocharged due to the phase lag between the exhaust stroke, which powers the turbocharger, and the intake stroke, when air is pumped into the engine. Our proposed method of turbocharging single cylinder engines is to add an ``air capacitor'' to the intake manifold, an additional volume that acts as a buffer to store compressed air between the exhaust and intake strokes, and smooth out the pressure pulses from the turbocharger. This talk presents experimental results from a single cylinder, turbocharged diesel engine fit with various sized air capacitors. Power output from the engine was measured using a dynamometer made from a generator, with the electrical power dissipated with resistive heating elements. We found that intake air density increases with capacitor size as theoretically predicted, ranging from 40 to 60 percent depending on heat transfer. Our experiment was able to produce 29 percent more power compared to using natural aspiration. These results validated that an air capacitor and turbocharger may be a simple, cost effective means of increasing the power density of single cylinder engines.

    Full Text Available 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.

Methods Preliminary work was performed by 7 working groups of stroke leaders followed by a synergium (a forum for working synergistically together) with approximately 100 additional participants. The resulting draft document had further input from contributors outside the synergium. Results Recommendations of the Synergium are: Basic Science, Drug Development and Technology: There is a need to develop: (1) New systems of working together to break down the prevalent ‘silo’ mentality; (2) New models of vertically integrated basic, clinical, and epidemiological disciplines; and (3) Efficient methods of identifying other relevant areas of science. Stroke Prevention: (1) Establish a global chronic disease prevention initiative with stroke as a major focus. (2) Recognize not only abrupt clinical stroke, but subtle subclinical stroke, the commonest type of cerebrovascular disease, leading to impairments of executive function. (3) Develop, implement and evaluate a population approach for stroke prevention. (4) Develop public health communication strategies using traditional and novel (e.g., social media/marketing) techniques. Acute Stroke Management: Continue the establishment of stroke centers, stroke units, regional systems of emergency stroke care and telestroke networks. Brain Recovery and Rehabilitation: (1) Translate best neuroscience, including animal and human studies, into poststroke recovery research and clinical care. (2) Standardize poststroke rehabilitation based on best evidence. (3) Develop consensus on, then implementation of, standardized clinical and surrogate assessments. (4) Carry out rigorous clinical research to advance stroke recovery. Into the 21st Century: Web, Technology and Communications: (1) Work toward global unrestricted access to stroke-related information. (2) Build

    stroke is predominantly a disease of older people. While age bias has been demonstrated in studies of pharmacological therapeutic interventions in stroke, the extent of discrimination by age in stroke rehabilitation studies is unknown. The aim of this study was to systematically review the literature to assess the extent of ageism in stroke rehabilitation studies. all randomised control trials (RCT) on stroke rehabilitation entered in the Cochrane database which reported mean age were included. Patient gender and exclusion criteria were also recorded. of 241 RCT's identified, 182 were eligible for inclusion. The mean age of all patients was 64.3, almost a decade younger than those seen by stroke physicians in daily practice in global terms, and 11-12 years younger than encountered in hospital practice in the British Isles. Almost half (46%) of trials excluded patients with cognitive impairment, almost one-quarter (23%) patients with dysphasia and one-eighth (13%) excluded patients with multiple strokes. we have identified a clear difference in the mean age of those included in stroke rehabilitation studies compared with the international mean age of stroke. In addition, a quarter of trials excluded dysphasic patients which may indicate omission of more severe strokes. This means that the evidence base for stroke rehabilitation is deficient in terms of matching the characteristics of patients encountered in clinical practice, and a more representative sample of older people and those with significant disability must be included in future trials.

Recommendations of the Synergium are: Basic Science, Drug Development and Technology: There is a need to develop: (1) New systems of working together to break down the prevalent 'silo' mentality; (2) New models of vertically integrated basic, clinical, and epidemiological disciplines; and (3) Efficient methods of identifying other relevant areas of science. Stroke Prevention: (1) Establish a global chronic disease prevention initiative with stroke as a major focus. (2) Recognize not only abrupt clinical stroke, but subtle subclinical stroke, the commonest type of cerebrovascular disease, leading to impairments of executive function. (3) Develop, implement and evaluate a population approach for stroke prevention. (4) Develop public health communication strategies using traditional and novel (eg, social media/marketing) techniques. Acute Stroke Management: Continue the establishment of stroke centers, stroke units, regional systems of emergency stroke care and telestroke networks. Brain Recovery and Rehabilitation: (1) Translate best neuroscience, including animal and human studies, into poststroke recovery research and clinical care. (2) Standardize poststroke rehabilitation based on best evidence. (3) Develop consensus on, then implementation of, standardized clinical and surrogate assessments. (4) Carry out rigorous clinical research to advance stroke recovery.

    Full Text Available NTRIDUCTION : Stroke is one of the important causes of morbidity and mortality all over the world. Incidence of stroke steadily increases with age. Experts are concerned of the emerging stroke epidemic in India. Stroke affecting the young has potentially devastating consequence son the individual and his family. Certain risk factors are unique to the young. I t needs more studies for identification and modification of risk factors. The study aims to evaluate clinical features, risk factors, etiology and mortality of stroke in young patients. METHODS : 74 young patients satisfying the inclusion criteria were included in this study. A detailed history was taken from young stroke patients, systemic examination and required investigations were done. Data was collected in standardized proforma and analysed. RESULTS: Stroke in young accounts for 7.95% of stroke cases of all age groups. The mean age of the patients was 34.66 ± 7.48 years. Among 74 patients, 47(63.51% were male and 27(36.49% were female. Seizures, decreased consciousness, speech involvement and motor deficit were observed in 33.78%, 44.59%, 22.97% and 100% of cases respectively. 82.43% patients had ischemic and 17.57% patients had hemorrhagic stroke. Among ischemic stroke, large artery atherosclerosis was 16.21%, tuberculous meningoencephalitis with vasculitis was 16.21%, lacunar stroke was 10.81%, CVT was 10.81% and cardio embolic stroke was 6.76%.

    Recurrent stroke is prevalent in both developed and developing countries, contributing significantly to disability and death. Recurrent stroke rates can be reduced by adequate risk factor management. However, adherence to prescribed medications and lifestyle changes recommended by physicians at discharge after stroke is poor, leading to a large number of preventable recurrent strokes. Using behavior change methods such as Motivational Interviewing early after stroke occurrence has the potential to prevent recurrent stroke. The overall aim of the study is to determine the effectiveness of motivational interviewing in improving adherence to medication and lifestyle changes recommended by treating physicians at and after hospital discharge in stroke patients 12 months poststroke to reduce risk factors for recurrent stroke. Recruitment of 430 first-ever stroke participants will occur in the Auckland and Waikato regions. Randomization will be to intervention or usual care groups. Participants randomized to intervention will receive four motivational interviews and five follow-up assessments over 12 months. Nonintervention participants will be assessed at the same time points. Primary outcome measures are changes in systolic blood pressure and low-density lipoprotein levels 12 months poststroke. Secondary outcomes include self-reported adherence and barriers to prescribed medications, new cardiovascular events (including stroke), changes in quality of life, and mood. The results of the motivational interviewing in stroke trial will add to our understanding of whether motivational interviewing may be potentially beneficial in the management of stroke and other diseases where similar lifestyle factors or medication adherence are relevant. © 2013 The Authors.

    The purpose of this study was to examine whether two different physiotherapy regimes caused any differences in outcome in the rehabilitation after stroke. We examined 240 patients with stroke. Examination was carried out at the Rehabilitation Center of Kaunas Second Clinical Hospital. Patients were divided into 2 groups: Bobath method was applied to the first (I) group (n=147), motor relearning program (MRP) method was applied to the second (II) group (n=93). In every group of patients we established samples according to sex, age, hospitalization to rehab unit as occurrence of CVA degree of disorder (hemiplegia, hemiparesis). The mobility of patients was evaluated according to European Federation for Research in Rehabilitation (EFRR) scale. Activities of daily living were evaluated by Barthel index. Analyzed groups were evaluated before physical therapy. When preliminary analysis was carried out it proved no statically reliable differences between analyzed groups (reliability 95%). The same statistical analysis was carried out after physical therapy. The results of differences between patient groups were compared using chi(2) method. Bobath method was applied working with the first group of patients. The aim of the method is to improve quality of the affected body side's movements in order to keep both sides working as harmoniously as possible. While applying this method at work, physical therapist guides patient's body on key-points, stimulating normal postural reactions, and training normal movement pattern. MRP method was used while working with the second group patients. This method is based on movement science, biomechanics and training of functional movement. Program is based on idea that movement pattern shouldn't be trained; it must be relearned. CONCLUSION. This study indicates that physiotherapy with task-oriented strategies represented by MRP, is preferable to physiotherapy with facilitation/inhibition strategies, such the Bobath programme, in the

    Intravenous thrombolysis (IVT) is beneficial in reducing disability in selected patients with acute ischemic stroke. There are numerous contraindications to IVT. One is recent surgery. The aim of this study was to analyze the safety of IVT in patients with postoperative stroke. Data of consecutive IVT patients from the Telemedical Project for Integrative Stroke Care thrombolysis registry (February 2003 to October 2014; n=4848) were retrospectively searched for keywords indicating preceding surgery. Patients were included if surgery was performed within the last 90 days before stroke. The primary outcome was defined as surgical site hemorrhage. Subgroups with major/minor surgery and recent/nonrecent surgery (within 10 days before IVT) were analyzed separately. One hundred thirty-four patients underwent surgical intervention before IVT. Surgery had been performed recently (days 1-10) in 49 (37%) and nonrecently (days 11-90) in 85 patients (63%). In 86 patients (64%), surgery was classified as major, and in 48 (36%) as minor. Nine patients (7%) developed surgical site hemorrhage after IVT, of whom 4 (3%) were serious, but none was fatal. One fatal bleeding occurred remotely from surgical area. Rate of surgical site hemorrhage was significantly higher in recent than in nonrecent surgery (14.3% versus 2.4%, respectively, odds ratio adjusted 10.73; 95% confidence interval, 1.88-61.27). Difference between patients with major and minor surgeries was less distinct (8.1% and 4.2%, respectively; odds ratio adjusted 4.03; 95% confidence interval, 0.65-25.04). Overall in-hospital mortality was 8.2%. Intracranial hemorrhage occurred in 9.7% and was asymptomatic in all cases. IVT may be administered safely in postoperative patients as off-label use after appropriate risk-benefit assessment. However, bleeding risk in surgical area should be taken into account particularly in patients who have undergone surgery shortly before stroke onset. © 2017 American Heart Association, Inc.

  14. Imaging of Hemorrhagic Stroke.

    Hemorrhagic stroke comprises approximately 15% to 20% of all strokes. This article provides readers with an understanding of the indications and significance of various neuroimaging techniques available for patients presenting with hemorrhagic strokes of distinct causes. The most common initial neuroimaging study is a noncontrast head CT, which allows for the identification of hemorrhage. Once an intracranial hemorrhage has been identified, the pattern of blood and the patient's medical history, neurologic examination, and laboratory studies lead the practitioner to pursue further neuroimaging studies to guide the medical, surgical, and interventional management. Given that hemorrhagic stroke constitutes a heterogeneous collection of diagnoses, the subsequent neuroimaging pathway necessary to better evaluate and care for these patients is variable based on the etiology.With an increasing incidence and prevalence of atrial fibrillation associated with the aging population and the introduction of three new direct factor Xa inhibitors and one direct thrombin inhibitor to complement vitamin K antagonists, oral anticoagulant use continues to increase. Patients on oral anticoagulants have a sevenfold to tenfold increased risk for intracerebral hemorrhage (ICH). Furthermore, patients who have an ICH associated with oral anticoagulant use have a higher mortality rate than those with primary ICH. Despite the reduced incidence of hypertension-related ICH over the past decade, it is expected that the incidence of ICH will continue to increase. Neuroimaging studies are integral to the identification of hemorrhagic stroke, determination of the underlying etiology, prevention of hematoma expansion, treatment of acute complications, and treatment of the underlying etiology, if indicated. Neuroimaging is essential for prognostication and thus directly impacts patient care.

    Organisational capacity in terms of resources and care circuits to shorten response times in new stroke cases is key to obtaining positive outcomes. This study compares therapeutic approaches and treatment outcomes between traditional care centres (with stroke teams and no stroke unit) and centres with stroke units. We conducted a prospective, quasi-experimental study (without randomisation of the units analysed) to draw comparisons between 2 centres with stroke units and 4 centres providing traditional care through the neurology department, analysing a selection of agreed indicators for monitoring quality of stroke care. A total of 225 patients participated in the study. In addition, self-administered questionnaires were used to collect patients' evaluations of the service and healthcare received. Centres with stroke units showed shorter response times after symptom onset, both in the time taken to arrive at the centre and in the time elapsed from patient's arrival at the hospital to diagnostic imaging. Hospitals with stroke units had greater capacity to respond through the application of intravenous thrombolysis than centres delivering traditional neurological care. Centres with stroke units showed a better fit to the reference standards for stroke response time, as calculated in the Quick study, than centres providing traditional care through the neurology department.

    Early diagnosis and treatment of a stroke improves patient outcomes, and knowledge of the cause of the initial event is crucial to identification of the appropriate therapy to maximally reduce risk of recurrence. Assumptions based on historical frequency of ischemic subtypes may need revision if stroke subtypes are changing as a result of recent changes in therapy, such as increased use of statins. We analyzed secular trends in stroke risk factors and ischemic stroke subtypes among patients with transient ischemic attack or minor or moderate stroke referred to an urgent transient ischemic attack clinic from 2002 to 2012. There was a significant decline in low-density lipoprotein cholesterol and blood pressure, associated with a significant decline in large artery stroke and small vessel stroke. The proportion of cardioembolic stroke increased from 26% in 2002 to 56% in 2012 (Prisk factors was observed, with a significant decline in stroke/transient ischemic attack caused by large artery atherosclerosis and small vessel disease. As a result, cardioembolic stroke/transient ischemic attack has increased significantly. Our findings suggest that more intensive investigation for cardiac sources of embolism and greater use of anticoagulation may be warranted. © 2014 American Heart Association, Inc.

    Rationale Prolonged sitting is associated with an increased risk of cardiovascular and all-cause mortality and morbidity. The metabolic and cardiovascular effects of breaking up sitting time in people with stroke are unknown. Aims and hypotheses To determine the (i) metabolic and cardiovascular effects and (ii) safety and feasibility of an experimental protocol to break up uninterrupted sitting in people with stroke. We hypothesize that activity breaks will attenuate the effects of uninterrupted sitting on glucose and insulin metabolism, blood pressure, lipid profiles, and plasma fibrinogen and that it will be both safe and feasible. Sample size estimate Based on previous estimates of population variability (SD 1% glucose and 30% insulin), 19 paired observations (i.e. participants) will achieve a power of 0.9 to detect a difference of 0.8% in glucose and 24% in insulin area under the curve (two-tailed testing, α = 0.05). Methods and design People with stroke will complete three experimental conditions one week apart in randomized order: (a) uninterrupted sitting, (b) prolonged sitting with intermittent walking, and (c) prolonged sitting with intermittent standing exercises. Serial blood samples will be collected and blood pressure measured at 30 min intervals for 8 h. Study outcomes Primary outcome will be postprandial glucose and insulin responses. Secondary outcomes will include fibrinogen concentrations, blood pressure, and adverse events and protocol feasibility. Discussion This is the first important step in determining the cardiovascular effects of breaking up sitting time after stroke. Findings will guide future studies testing behavioral strategies to reduce sitting time for the purpose of lowering recurrent stroke risk.

    Full Text Available Stroke scales can be classified as clinicometric scales and functional impairment, handicap scales. All studies describing stroke scales were reviewed by internet searching engines with the final search performed on January 1, 2013. The following string of keywords was entered into search engines; stroke, scale, score and disability. Despite advantages of modified National Institute of Health Stroke Scale and Scandinavian stroke scale comparing to the NIHSS, including their simplification and less inter-rater variability; most of the stroke neurologists around the world continue using the NIHSS. The modified Rankin scale (mRS and Barthel index (BI are widely used functional impairment and disability scales. Distinction between grades of mRS is poorly defined. The Asian stroke disability scale is a simplified functional impairment, handicap scale which is as valid as mRS and BI. At the present time, the NIHSS, mRS and BI are routine stroke scales because physicians have used to work with these scales for more than two decades, although it could not be an acceptable reason. On the other side, results of previous stroke trials, which are the basis of stroke management guidelines are driven using these scales.

    To provide a comprehensive review of the current evidence on post-stroke urinary incontinence. An electronic database search was performed to identify relevant studies and review articles related to Urinary Incontinence (UI) in the stroke population between the years 1966 and 2012. Urinary incontinence following stroke is a common problem affecting more than one-third of acute stroke patients and persisting in up to a quarter at 1 year. It is well established that this condition is a strong marker of stroke severity and is associated with poorer functional outcomes and increased institutionalisation and mortality rates compared with those who remain continent. Despite evidence linking better outcomes to those patients who regain continence, the results of national audits have demonstrated that the management of UI following stroke is suboptimal, with less than two-thirds of stroke units having a documented plan to promote continence. Current evidence supports a thorough assessment to categorise the type and severity of post-stroke urinary incontinence. An individually tailored, structured management strategy to promote continence should be employed. This has been associated with better stroke outcomes and should be the aim of all stroke health professionals. © 2013 John Wiley & Sons Ltd.

    Background Cardiovascular events while driving have occasionally been reported. In contrast, there have been few studies on stroke while driving. Aim The objectives of this study were to (1) report the frequency of stroke while driving and (2) evaluate its association with automobile accidents. Methods Clinical data prospectively acquired between January 2011 and December 2016 on 2145 stroke patients (1301 with ischemic stroke, 585 with intracerebral hemorrhage, and 259 with subarachnoid hemorrhage) were reviewed to identify patients who sustained a stroke while driving. The ratio of driving to performing other activities was evaluated for each stroke type. Furthermore, the drivers' response to stroke was reviewed to understand how automobile accidents occurred. Results Among the 2145 patients, 85 (63 ischemic stroke, 20 intracerebral hemorrhage, and 2 subarachnoid hemorrhage) sustained a stroke while driving. The ratio of driving to performing other activities was significantly higher in ischemic stroke (4.8%) than in intracerebral hemorrhage (3.4%) or subarachnoid hemorrhage (0.8%). A majority of drivers either continued driving or pulled over to the roadside after suffering a stroke. However, 14 (16%) patients were involved in automobile accidents. In most patients, an altered mental status due to severe stroke was the presumed cause of the accident. Conclusion Stroke occurred while driving in 4.0% of all strokes and accidents occurred in 16% of these instances.

    the National Service Framework for Older People requires every general hospital which cares for stroke patients to introduce a specialist stroke service by 2004. to describe the organisation and staffing of specialist hospital-based stroke services in the UK. a national postal survey of consultant members of the British Association of Stroke Physicians (BASP) seeking details of the provision of neurovascular clinics, acute stroke units (ASUs), stroke rehabilitation units (SRUs), and the organisation and staffing of these services. the response rate was 91/126 (72%). Fifty-four neurovascular clinics, 40 ASUs and 68 SRUs were identified. Neurovascular clinics used a number of strategies to maintain rapid access and 30 (56%) were run by a single consultant. Only 50% ASUs usually admitted patients within 24 h of stroke. As the number of beds available on ASUs and SRUs did not reflect the total number of stroke in-patients, 21 (53%) ASUs and 45 (79%) SRUs had admission criteria. Training opportunities were limited: 37% ASUs and 82% SRUs had no specialist registrar. The therapy sessions (1 session=half a day) available per bed per week on a SRU were: physiotherapy 0.8; occupational therapy 0.6; speech and language therapy 0.25. significant development is needed to achieve the NSF target for hospital-based stroke services as few Trusts currently have all components in place and even when available not all stroke patients have access to specialist care. Stroke specialists will be required to run these services but training opportunities are currently limited. Stroke unit therapy staffing levels were lower than was available in randomised controlled trials.

    Full Text Available Abstract Background The central circadian pacemaker is a remarkably robust regulator of daily rhythmic variations of cardiovascular, endocrine, and neural physiology. Environmental lighting conditions are powerful modulators of circadian rhythms, but regulation of circadian rhythms by disease states is less clear. Here, we examine the effect of ischemic stroke on circadian rhythms in rats using high-resolution pineal microdialysis. Methods Rats were housed in LD 12:12 h conditions and monitored by pineal microdialysis to determine baseline melatonin timing profiles. After demonstration that the circadian expression of melatonin was at steady state, rats were subjected to experimental stroke using two-hour intralumenal filament occlusion of the middle cerebral artery. The animals were returned to their cages, and melatonin monitoring was resumed. The timing of onset, offset, and duration of melatonin secretion were calculated before and after stroke to determine changes in circadian rhythms of melatonin secretion. At the end of the monitoring period, brains were analyzed to determine infarct volume. Results Rats demonstrated immediate shifts in melatonin timing after stroke. We observed a broad range of perturbations in melatonin timing in subsequent days, with rats exhibiting onset/offset patterns which included: advance/advance, advance/delay, delay/advance, and delay/delay. Melatonin rhythms displayed prolonged instability several days after stroke, with a majority of rats showing a day-to-day alternation between advance and delay in melatonin onset and duration. Duration of melatonin secretion changed in response to stroke, and this change was strongly determined by the shift in melatonin onset time. There was no correlation between infarct size and the direction or amplitude of melatonin phase shifting. Conclusion This is the first demonstration that stroke induces immediate changes in the timing of pineal melatonin secretion, indicating

    Delirium is an acute neuropsychiatric syndrome, very common in hospitalized people with medical and neurological conditions. The identification of delirium after stroke is not an easy task and validated psychometric instruments are needed to correctly identify it. We decided to verify if (1) formal training in DSM-V criteria is needed to correctly identify post-stroke delirium, (2) if the use of a brief psychometric instrument such as 4AT improves its identification, (3) the applicability of these scales in the stroke setting. In the first phase of this study we retrospectively studied 102 acute stroke patients in Stroke Units of San Martino Hospital (Genova, Italy) to evaluate delirium with clinical criteria, first by a neurologist without a formal training in DSM-V criteria and after training. Then, we enrolled 100 new acute stroke patients who underwent screening for delirium using 4AT scale and DSM-V criteria. In the first phase, DSM-V criteria training significantly increased the ability to capture delirium (5 vs. 15%). In the second phase, the 4AT was used for delirium screening revealing a 52% of cases of delirium, the same observed by the consensus diagnosis of two senior neurologists (that was 50%). In the second phase, the use of 4AT scale allowed to capture post-stroke delirium as well as the consensus diagnosis by two neurologists. The identification of post-stroke delirium is not an easy task and requires both formal training in DSM-V criteria as well as the application of brief scales, such as the 4AT.

    Full Text Available The deterioration of the balance between direct and indirect ways in the basal ganglia causes chorea. The lesions of contralateral basal ganglia, thalamus or the connection of them all together are responsible for this. Chorea can be observed during the course of metabolic and vascular diseases, neurodegenerative or hereditary diseases. Hyperkinetic movement disorders after acute ischemic stroke are reported as rare; however, hemichorea is the most frequent developing disorder of hyperkinetic movement as a result of cerebrovascular disease. In this case report, we presented two case who applied us with choreiform movements in his left half of the body after acute thalamic stroke. [Cukurova Med J 2016; 41(0.100: 29-32

  13. [Smoking and stroke].

    Cigarette smoking is a risk factor for the brain infarction (lacunar and atherothrombotic brain infarction) and subarachnoid hemorrhage. Not only active smoking but also passive smoking and smokeless tobacco products pose a risk. The risk after smoking cessation for 5-10 years is equal to that faced by a non-smoker. Many patients continue smoking even after an attack of stroke; therefore, support measures to enforce nonsmoking are required in this high-risk population. We offer nonsmoking support using the 5A approach, and assess the nonsmoking stage (precontemplation, contemplation, preparation, action, and maintenance). We also administer medical therapy for smoking cessation when the patients find it difficult to quit smoking on their own accord. Nicotine dependency needs a follow-up like that required for other risk factors in the primary and secondary prevention of the stroke because smoking is a chronic disease that tends to recur.

    Full Text Available BACKGROUND: We hypothesized that hidden malignancy could be detected in patients with cryptogenic stroke without active cancer when they showed the distinctive characteristics of cancer-related stroke. METHODS AND FINDINGS: Among 2,562 consecutive patients with acute ischemic stroke, patients with cryptogenic stroke were analyzed and categorized into two groups according to the presence of active cancer: cryptogenic stroke with active cancer (cancer-related stroke, CA-stroke group and without active cancer (CR-stroke group. Patients with active lung cancer without stroke were also recruited for comparison purposes (CA-control. Clinical factors, lesion patterns on diffusion-weighted MRI (DWI, and laboratory findings were analyzed among groups. A total of 348 patients with cryptogenic stroke were enrolled in this study. Among them, 71 (20.4% patients had active cancer at the time of stroke. The D-dimer levels were significantly higher in patients with CA-stroke than those with CR-stroke or CA-control (both p<0.001. Regarding lesion patterns, patients with CA-stroke mostly had multiple lesions in multiple vascular territories, while more than 80% of patients with CR-stroke had single/multiple lesions in a single vascular territory (P<0.001. D-dimer levels (OR 1.11 per 1 µg/mL increase; 95% CI 1.06-1.15; P<0.001 and DWI lesion patterns (OR 7.13; 95% CI 3.42-14.87; P<0.001 were independently associated with CA-stroke. Workup for hidden malignancy was performed during hospitalization in 10 patients who showed elevated D-dimer levels and multiple infarcts involving multiple vascular territories but had no known cancer, and it revealed hidden malignancies in all the patients. CONCLUSION: Patients with CA-stroke have distinctive D-dimer levels and lesion patterns. These characteristics can serve as clues to occult cancer in patients with cryptogenic stroke.

    Full Text Available AbstractBackground: There are significant racial disparities in stroke incidence and mortality. Health fairs and outreach programs can be used to increase stroke literacy, but they often fail to reach those at highest risk, including African American males. Methods: We conducted a stroke outreach and screening program at an inner city market in order to attract a high-risk group for a stroke education intervention. A modified Framingham risk tool was used to estimate stroke risk and a 10-item quiz was developed to assess stroke literacy among 80 participants. We report results of the demographic and stroke risk analyses and stroke knowledge assessment. Results: The program attracted a majority male (70% and African American (95% group of participants. Self-reported hypertension (57.5%, tobacco use (40%, and diabetes (23.8% were prevalent. Knowledge of stroke warning signs, risk factors, and appropriate action to take for stroke symptoms was not poor when compared to the literature. Conclusions: Stroke outreach and screening in an inner city public market may be an effective way to target a high-risk population for stroke prevention interventions. Stroke risk among participants was high despite adequate stroke knowledge.

    2017-02-01

    Early rehabilitation is recommended in many guidelines, with limited evidence to guide practice. Brain neurobiology suggests that early training, at the right dose, will aid recovery. In this review, we highlight recent trials of early mobilization, aphasia, dysphagia and upper limb treatment in which intervention is commenced within 7 days of stroke and discuss future research directions. Trials in this early time window are few. Although the seminal AVERT trial suggests that a cautious approach is necessary immediately (stroke, early mobility training and mobilization appear well tolerated, with few reasons to delay initiating some rehabilitation within the first week. The results of large clinical trials of early aphasia therapy are on the horizon, and examples of targeted upper limb treatments with better patient selection are emerging. Early rehabilitation trials are complex, particularly those that intervene across acute and rehabilitation care settings, but these trials are important if we are to optimize recovery potential in the critical window for repair. Concerted efforts to standardize 'early' recruitment, appropriately stratify participants and implement longer term follow-up is needed. Trial standards are improving. New recommendations from a recent Stroke Recovery and Rehabilitation Roundtable will help drive new research.

    2009-01-01

    Blood glucose is often elevated in acute stroke, and higher admission glucose levels are associated with larger lesions, greater mortality and poorer functional outcome. In patients treated with thrombolysis, hyperglycemia is associated with an increased risk of hemorrhagic transformation...... to the risk of inducing potentially harmful hypoglycemia has been raised. Still, basic and observational research is overwhelmingly in support of a causal relationship between blood glucose and stroke outcome and further research on glucose-lowering therapy in acute stroke is highly warranted....

    In Cambodia, stroke is not ranked among the top 10 leading causes of death, but infectious disease are among the top three leading causes of death. This finding could be attributed to a lack of awareness among Cambodians of the signs and symptoms of stroke or to poor reporting, incomplete data, lack of neurologists and neurosurgeons, or low accessibility to the hospitals. The only study of stroke in Cambodia is the Prevalence of Non-Communicable Disease Risk Factors in Cambodia survey, which identified several stroke-related risk factors in the population. Tobacco chewing or smoking is the main risk factor for stroke in Cambodia. Traditional therapies, such as oyt pleung (moxibustion) and jup (cupping), are widely practiced for stroke rehabilitation. In Cambodia, there are few neurologists and few important equipment, such as magnetic resonance imaging machines and computed tomography scanners. The Cambodian government should cooperate with the World Health Organization and the United Nations Children's Fund to attract foreign expertise and technologies to treat stroke patients. © 2012 The Authors.

    2013-01-01

    Full Text Available Background: Stroke is a leading cause of death and acquired disability worldwide. In Europe, strokes account for almost 1.1 million death per year. In particular, countries in Southern Europe constitute populations with a different lifestyle and dietary habits from those in Northern Europe and that may influence stroke incidence, type and risk factors.Aim: The objective of this study was to review and summarise the trends of the incidence of stroke in Southern Europe, as well as,to mention stroke subtypes and recognise the risk factors for stroke.Methods: A systematic review in PubMed was conducted.Results: Therefore, twenty-three articles, representing seven countries, related to incidence, type and risk factors of stroke in this specific geographical area of Europe were identified. The annual stroke incidence varied from approximately 1.41 to 3.73 per 1000 population per year. Currently, in all the countries studied, ischemic stroke was the commonest stroke type in all series. Hypertension remains the main risk factor for both ischemic andhemorrhagic strokes, followed by diabetes mellitus, hyperlipidemia and other factors.Conclusions: A wide range of stroke incidence may be due to the different lifestyle and behavioural factors among countries. Further research that uses the best possible methods to study the incidence, type and risk factors of stroke are urgently needed in Balkan Peninsula.

    Stroke is a clinically syndrome of a sudden onset of neurological deficit in a vascular cause. Stroke mimics is the non-vascular disorders with stroke-like clinical symptoms. It is important to distinguish true stroke from mimics since treatment plan may differ To determine the incidence of the stroke mimics and identify their etiologies. All non-contrast head CT of the patients with clinically diagnosed stroke who immediately received imaging upon arrival at the emergency department of the university hospital were retrospectively reviewed in 12-month period between January 1 and December 31, 2008. Medical records, laboratory results, MRI, and 6-month clinical follow-up records were reviewed for final diagnosis. Seven hundred four patients were included in this study, including 363 (51.5%) men and 341 (48.5%) women with range in age from 24 to 108 years. Amongst those, 417 (59.2%) were ischemic stroke, 80 (11.40%) were hemorrhagic stroke, 186 (26.4%) were stroke-mimics, and 21 (3%) were inconclusive. The etiologies among stroke-mimics were metabolic/intoxication (35, 18.8%), sepsis (28, 15.0%), seizure (21, 11.3%), syncope (20, 10.8%), subdural hemorrhage (14, 7.5%), vertigo (11, 6.0%), brain tumor (10, 5.30%), central nervous system infection (5, 2.7%), others (26, 14.0%), and unspecified (16, 8.6%). Incidence rates and etiologies of the stroke mimics were similar to the western reports. However the frequency of each mimic was not.

  8. Thrombin Generation in Acute Ischaemic Stroke

    2016-01-01

    Full Text Available Introduction. Stroke remains a global leading cause of death and disability. Traditional description of plasma biology in the aftermath of acute ischaemic stroke favours development of hypercoagulability, resulting from complex interplay between plasma and endothelial factors. However, no single assay measures the overall global coagulation process. We postulate that thrombin generation would assist in identifying coagulation abnormalities after acute stroke. Aim. To investigate the coagulation abnormalities after acute ischaemic stroke using thrombin generation. Methods. We evaluated thrombin generation, measured with calibrated automated thrombography in stroke of different aetiological types (n=170 within 48 hours of symptoms onset (baseline and in the second week (time 2 and in normal healthy volunteers (n=71. Results. Two-point thrombin generation assays showed prolonged lag time and time to peak at baseline (3.3 (2.9, 4.0 versus 3.6 (3.2, 4.7; p=0.005 and (3.3 (2.9, 4.0 versus 3.6 (3.2, 4.7; p=0.002, respectively, and at time 2 (3.5 (2.9, 4.2 versus 4.0 (3.1, 4.9; p=0.004 and (5.9 (5.3, 6.6 versus 6.8 (5.8, 7.7 p=0.05, respectively, in cardioembolic stroke (n=39, when compared to noncardioembolic stroke (n=117. The result was reproduced in multiple comparisons between acute ischaemic stroke subgroups and normal healthy volunteers. Endogenous thrombin potential and peak thrombin did not indicate hypercoagulability after acute ischaemic stroke, and thrombolytic therapy did not affect thrombin generation assays. Conclusion. Our findings suggest that thrombin generation in platelet poor plasma is not useful in defining hypercoagulability in acute ischaemic stroke. This is similar to observed trend in coronary artery disease and contrary to other hypercoagulable states.

    Cancer is a risk factor for ischemic stroke. Little is known about cancer among young adults with ischemic stroke. We studied the frequency of cancer and its association with long-term risk of death among young patients with first-ever ischemic stroke. 1002 patients aged 15 to 49 years, registered in the Helsinki Young Stroke Registry, and with a median follow-up of 10.0 years (interquartile range 6.5-13.8) after stroke were included. Historical and follow-up data were derived from the Finnish Care Register and Statistics Finland. Survival between groups was compared with the Kaplan-Meier life-table method, and Cox proportional hazard models were used to identify factors associated with mortality. One or more cancer diagnosis was made in 77 (7.7%) patients, of whom 39 (3.9%) had cancer diagnosed prestroke. During the poststroke follow-up, 41 (53.2%) of the cancer patients died. Median time from prestroke cancer to stroke was 4.9 (1.0-9.5) years and from stroke to poststroke cancer was 6.7 (2.7-10.9) years. Poststroke cancer was associated with age>40 years, heavy drinking, and cigarette smoking. The cumulative mortality was significantly higher among the cancer patients (68.6%, 95% confidence interval 52.0%-85.3%) compared with patients without cancer (19.7%, 95% confidence interval 16.3%-23.2%). Active cancer at index stroke, melanoma, and lung/respiratory tract cancer had the strongest independent association with death during the follow-up when adjusted for known poststroke mortality prognosticators. Cancer, and especially active cancer and no other apparent cause for stroke, is associated with unfavorable survival among young stroke patients. © 2015 American Heart Association, Inc.

    Information technology and mobile devices may be beneficial and useful in many aspects of stroke management, including recognition of stroke, transport and triage of patients, emergent stroke evaluation at the hospital, and rehabilitation. In this review, we address the contributions of information technology and mobile health to stroke management. Rapid detection and triage are essential for effective thrombolytic treatment. Awareness of stroke warning signs and responses to stroke could be enhanced by using mobile applications. Furthermore, prehospital assessment and notification could be streamlined for use in telemedicine and teleradiology. A mobile telemedicine system for assessing the National Institutes of Health Stroke Scale scores has shown higher correlation and fast assessment comparing with face-to-face method. Because the benefits of thrombolytic treatment are time-dependent, treatment should be initiated as quickly as possible. In-hospital communication between multidisciplinary team members can be enhanced using information technology. A computerized in-hospital alert system using computerized physician-order entry was shown to be effective in reducing the time intervals from hospital arrival to medical evaluations and thrombolytic treatment. Mobile devices can also be used as supplementary tools for neurologic examination and clinical decision-making. In post-stroke rehabilitation, virtual reality and telerehabilitation are helpful. Mobile applications might be useful for public awareness, lifestyle modification, and education/training of healthcare professionals. Information technology and mobile health are useful tools for management of stroke patients from the acute period to rehabilitation. Further improvement of technology will change and enhance stroke prevention and treatment.

    To describe the epidemiology and clinical features of stroke in a prospective and retrospective cohort of Saudi children and ascertain the causes, pathogenesis, and risk factors. The Retrospective Study Group (RSG) included children with stroke who were evaluated at the Division of Pediatric Neurology, or admitted to King Khalid University Hospital, College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia during the period July 1992 to February 2001. The Prospective Study Group (PSG) included those seen between February 2001 and March 2003. During the combined study periods of 10 years and 7 months, 117 children (61 males and 56 females, aged one month-12 years) were evaluated; the majority (89%) of these were Saudis. The calculated annual hospital frequency rate of stroke was 27.1/100,000 of the pediatric (1month-12 years) population The mean age at onset of the initial stroke in the 104 Saudi children was 27.1 months (SD=39.3 months) median and median was 6 months. Ischemic strokes accounted for the majority of cases (76%). Large-vessel infarcts (LVI, 51.9%) were more common than small-vessel lacunar lesions (SVLL, 19.2%). Five patients (4.8%) had combined LVI and SVLL. Intracranial hemorrhage was less common (18.2%), whereas sinovenous thrombosis was diagnosed in 6 (5.8%) patients. A major risk factor was identified in 94 of 104 (89.4%) Saudi children. Significantly more hematologic disorders and coagulopathies were identified in the PSG compared to the RSG (p=0.001), reflecting a better yield following introduction of more comprehensive hematologic and cogulation laboratory tests during the prospective study period. Hematologic disorders were the most common risk factor (46.2%); presumed perinatal ischemic cerebral injury was risk factor in 23 children (22.1) and infectious and inflammatory disorders of the circulatory system in 18 (17.3%). Congenital and genetic cerebrovascular anomalies were the underlying cause in 7 patients (6.7%) and

    2011-01-01

    Stroke often results in both motor and sensory deficits, which may interact in the manifested functional impairment. Proprioception is known to play important roles in the planning and control of limb posture and movement; however, the impact of proprioceptive deficits on motor function has been difficult to elucidate due in part to the qualitative nature of available clinical tests. We present a quantitative and standardized method for evaluating proprioception in tasks directly relevant to those used to assess motor function. Using a robotic manipulandum that exerted controlled displacements of the hand, stroke participants were evaluated, and compared with a control group, in their ability to detect such displacements in a 2-alternative, forced-choice paradigm. A psychometric function parameterized the decision process underlying the detection of the hand displacements. The shape of this function was determined by a signal detection threshold and by the variability of the response about this threshold. Our automatic procedure differentiates between participants with and without proprioceptive deficits and quantifies functional proprioceptive sensation on a magnitude scale that is meaningful for ongoing studies of degraded motor function in comparable horizontal movements.

    1992-09-01

    Using the electrical impedance measurement technique to investigate stroke volume estimation, three models of the ventricle were simulated. A four-electrode impedance catheter was used; two electrodes to set up an electric field in the model and the other two to measure the potential difference. A new approach, itself an application of the quasi-static case of a method used to solve electromagnetic field problems, was used to solve the electric field in the model. The behaviour of the estimation is examined with respect to the electrode configuration on the catheter and to catheter location with respect to the ventricle walls. Cardiac stroke volume estimation was found to be robust to catheter location generating a 10 per cent error for an offset of 40 per cent of the catheter from the chamber axis and rotation of 20 degrees with respect to the axis. The electrode configuration has a dominant effect on the sensitivity and accuracy of the estimation. Certain configurations gave high accuracy, whereas in others high sensitivity was found with lower accuracy. This led to the conclusion that the electrode configuration should be carefully chosen according to the desired criteria.

    2018-01-01

    In Germany, patient information and expert testimony on driving ability requires knowledge of the corresponding legislation and the Guideline for expertises on driver aptitude. The testimony should clearly identify handicaps with regard to driving, give estimates on the future risks of a sudden loss of control, and also consider personal attitudes such as inadequate behavior, lack of insight etc. Physical handicaps often can be compensated for by restrains or restrictions such as vehicle modifications, daylight driving only etc.Both, information and testimony must give estimates on the risks of a sudden loss of control while driving by stroke recurrence or epileptic seizures. In accordance with the Risk-of-Harm-Formula of the Canadian Cardiovascular Society methods are being discussed, by which an estimate of harmful traffic accidents due to stroke recurrence can be calculated.

    2003-02-01

    Full Text Available Abstract Background Stroke is a major cause of death and long-term disability in Western societies and constitutes a major claim on health care budgets. Organising stroke care in a stroke service has recently been demonstrated to result in better health effects for patients. This paper discusses patient costs after stroke and compares costs between regular and stroke service care. Methods Costs were calculated within the framework of the evaluation of three experiments with stroke services in the Netherlands. Cost calculations are base on medical consumption data and actual costs. Results 598 patients were consecutively admitted to hospital after stroke. The average total costs of care per patient for the 6 month follow-up are estimated at €16,000. Costs are dominated by institutional and accommodation costs. Patients who die after stroke incur less costs. For patients that survive the acute phase, the most important determinants of costs are disability status and having a partner – as they influence patients' stroke careers. These determinants also interact. The most efficient stroke service experiment was most successful in co-ordinating patient flow from hospital to (nursing home, through capacity planning and efficient discharge procedures. In this region the costs of stroke service care are the same as for regular stroke care. The other experiments suffered from waiting lists for nursing homes and home care, leading to "blocked beds" in hospitals and nursing homes and higher costs of care. Costs of co-ordination are estimated at about 3% of total costs of care. Conclusion This paper demonstrates that by organising care for stroke patients in a stroke service, better health effects can be achieved with the same budget. In addition, it provides insight in need, predisposing and enabling factors that determine costs of care after stroke.

    Previous studies examining social work interventions in stroke often lack information on content, methods and timing over different phases of care including acute hospital, rehabilitation and out-patient care. This limits our ability to evaluate the impact of social work in multidisciplinary stroke care. We aimed to quantify social-work-related support in stroke patients and their carers in terms of timing and content, depending on the different phases of stroke care. We prospectively collected and evaluated data derived from a specialized "Stroke-Service-Point" (SSP); a "drop in" center and non-medical stroke assistance service, staffed by social workers and available to all stroke patients, their carers and members of the public in the metropolitan region of Berlin, Germany. Enquiries from 257 consenting participants consulting the SSP between March 2010 and April 2012 related to out-patient and in-patient services, therapeutic services, medical questions, medical rehabilitation, self-help groups and questions around obtaining benefits. Frequency of enquiries for different topics depended on whether patients were located in an in-patient or out-patient setting. The majority of contacts involved information provision. While the proportion of male and female patients with stroke was similar, about two thirds of the carers contacting the SSP were female. The social-work-related services provided by a specialized center in a German metropolitan area were diverse in terms of topic and timing depending on the phase of stroke care. Targeting the timing of interventions might be important to increase the impact of social work on patient's outcome.

    Full Text Available Introduction: The quality of integrated stroke care depends on smooth team functioning but professionals may not always work well together. Professionals' perspectives on the factors that influence stroke team functioning remain largely unexamined. Understanding their experiences is critical to indentifying measures to improve team functioning. The aim of this study was to identify the factors that contributed to the success of interprofessional stroke teams as perceived by team members.  Methods: We distributed questionnaires to professionals within 34 integrated stroke care teams at various health care facilities in 9 Dutch regions. 558 respondents (response rate: 39% completed the questionnaire. To account for the hierarchical structure of the study design we fitted a hierarchical random-effects model. The hierarchical structure comprised 558 stroke team members (level 1 nested in 34 teams (level 2.  Results: Analyses showed that personal development, social well-being, interprofessional education, communication, and role understanding significantly contributed to stroke team functioning. Team-level constructs affecting interprofessional stroke team functioning were communication and role understanding. No significant relationships were found with individual-level personal autonomy and team-level cohesion.  Discussion and conclusion: Our findings suggest that interventions to improve team members' social well-being, communication, and role understanding will improve teams' performance. To further advance interprofessional team functioning, healthcare organizations should pay attention to developing professionals' interpersonal skills and interprofessional education.

    Computational analysis of swallowing mechanics (CASM) is a method that utilizes multivariate shape change analysis to uncover covariant elements of pharyngeal swallowing mechanics associated with impairment using videofluoroscopic swallowing studies. The goals of this preliminary study were to (1) characterize swallowing mechanics underlying stroke-related dysphagia, (2) decipher the impact of left and right hemispheric strokes on pharyngeal swallowing mechanics, and (3) determine pharyngeal swallowing mechanics associated with penetration-aspiration status. Videofluoroscopic swallowing studies of 18 dysphagic patients with hemispheric infarcts and age- and gender-matched controls were selected from well-controlled data sets. Patient data including laterality and penetration-aspiration status were collected. Coordinates mapping muscle group action during swallowing were collected from videos. Multivariate morphometric analyses of coordinates associated with stroke, affected hemisphere, and penetration-aspiration status were performed. Pharyngeal swallowing mechanics differed significantly in the following comparisons: stroke versus controls (D = 2.19, P mechanics associated with each comparison were visualized using eigenvectors. Whereas current literature focuses on timing changes in stroke-related dysphagia, these data suggest that mechanical changes are also functionally important. Pharyngeal swallowing mechanics differed by the affected hemisphere and the penetration-aspiration status. CASM can be used to identify patient-specific swallowing impairment associated with stroke injury that could help guide rehabilitation strategies to improve swallowing outcomes.

    2012-01-01

    Full Text Available The aim of this paper was to examine the amount and type of physical activity engaged in by people hospitalised after stroke. Method. We systematically reviewed the literature for observational studies describing the physical activity of stroke patients. Results. Behavioural mapping, video recording and therapist report are used to monitor activity levels in hospitalised stroke patients in the 24 included studies. Most of the patient day is spent inactive (median 48.1%, IQR 39.6%–69.3%, alone (median 53.7%, IQR 44.2%–60.6% and in their bedroom (median 56.5%, IQR 45.2%–72.5%. Approximately one hour per day is spent in physiotherapy (median 63.2 minutes, IQR 36.0–79.5 and occupational therapy (median 57.0 minutes, IQR 25.1–58.5. Even in formal therapy sessions limited time is spent in moderate to high level physical activity. Low levels of physical activity appear more common in patients within 14 days post-stroke and those admitted to conventional care. Conclusions. Physical activity levels are low in hospitalised stroke patients. Improving the description and classification of post stroke physical activity would enhance our ability to pool data across observational studies. The importance of increasing activity levels and the effectiveness of interventions to increase physical activity after stroke need to be tested further.

    The recent “Advanced Neuroimaging for Acute Stroke Treatment” meeting on September 7 and 8, 2007 in Washington DC, brought together stroke neurologists, neuroradiologists, emergency physicians, neuroimaging research scientists, members of the National Institute of Neurological Disorders and Stroke (NINDS), the National Institute of Biomedical Imaging and Bioengineering (NIBIB), industry representatives, and members of the US Food and Drug Administration (FDA) to discuss the role of advanced neuroimaging in acute stroke treatment. The goals of the meeting were to assess state-of-the-art practice in terms of acute stroke imaging research and to propose specific recommendations regarding: (1) the standardization of perfusion and penumbral imaging techniques, (2) the validation of the accuracy and clinical utility of imaging markers of the ischemic penumbra, (3) the validation of imaging biomarkers relevant to clinical outcomes, and (4) the creation of a central repository to achieve these goals. The present article summarizes these recommendations and examines practical steps to achieve them. PMID:18477656

    2005-01-01

    Full Text Available Auditory hallucinations are uncommon phenomena which can be directly caused by acute stroke, mostly described after lesions of the brain stem, very rarely reported after cortical strokes. The purpose of this study is to determine the frequency of this phenomenon. In a cross sectional study, 641 stroke patients were followed in the period between 1996–2000. Each patient underwent comprehensive investigation and follow-up. Four patients were found to have post cortical stroke auditory hallucinations. All of them occurred after an ischemic lesion of the right temporal lobe. After no more than four months, all patients were symptom-free and without therapy. The fact the auditory hallucinations may be of cortical origin must be taken into consideration in the treatment of stroke patients. The phenomenon may be completely reversible after a couple of months.

    Given that stroke is currently a serious problem in the population, employing more reliable and objective techniques for determining diagnosis and prognosis is necessary in order to enable effective clinical decision-making. EEG is a simple, low-cost, non-invasive tool that can provide information about the changes occurring in the cerebral cortex during the recovery process after stroke. EEG provides data on the evolution of cortical activation patterns which can be used to establish a prognosis geared toward harnessing each patient's full potential. This strategy can be used to prevent compensation and maladaptive plasticity, redirect treatments, and develop new interventions that will let stroke patients reach their new maximum motor levels.

    A. Pyae

    2015-07-01

    Full Text Available Stroke is one of the major problems in medical and healthcare that can cause severe disability and death of patients especially for older population. Rehabilitation plays an important role in stroke therapy. However, most of the rehabilitative exercises are monotonous and tiring for the patients. For a particular time, they can easily get bored in doing these exercises. The role of patient’s motivation in rehabilitation is vital. Motivation and rehabilitative outcomes are strongly related. Digital games promise to help stroke patients to feel motivated and more engaged in rehabilitative training through motivational gameplay. Most of the commercial games available in the market are not well-designed for stroke patients and their motivational needs in rehabilitation. This study aims at understanding the motivational requirements of stroke patients in doing rehabilitative exercises and living in a post-stroke life. Based on the findings from the literature review, we report factors that can influence the stroke patients’ level of motivation such as social functioning, patient-therapist relationship, goal-setting, and music. These findings are insightful and useful for ideating and designing interactive motivation-driven games for stroke patients. The motivational factors of stroke patients in rehabilitation may help the game designers to design motivation-driven game contexts, contents, and gameplay. Moreover, these findings may also help healthcare professionals who concern stroke patient’s motivation in rehabilitative context. In this paper, we reported our Virtual Nursing Home (VNH concept and the games that we are currently developing and re-designing. Based on this literature review, we will present and test out the ideas how we can integrate these motivational factors in our future game design, development, and enhancement.

  7. Basics of acute stroke treatment

    International Nuclear Information System (INIS)

    Haass, A.

    2005-01-01

    Acute stroke presents an emergency that requires immediate referral to a specialized hospital, preferably with a stroke unit. Disability and mortality are reduced by 30% in patients treated in stroke units compared to those treated on regular wards, even if a specialized team is present on the ward. Systolic blood pressure may remain high at 200-220 mmHg in the acute phase and should not be lowered too quickly. Further guidelines for basic care include: optimal O 2 delivery, blood sugar levels below 100-150 mg%, and lowering body temperature below 37.5 C using physical means or drugs. Increased intracranial pressure should be treated by raising the upper body of the patient, administration of glycerol, mannitol, and/or sorbitol, artificial respiration, and special monitoring of Tris buffer. Decompressive craniectomy may be considered in cases of ''malignant'' media stroke and expansive cerebellar infarction. Fibrinolysis is the most effective stroke treatment and is twice as effective in the treatment of stroke than myocardial infarction. Fibrinolysis may be initiated within 3 h of a stroke in the anterior circulation. If a penumbra is detectable by ''PWI-DWI mismatch MRI,'' specialized hospitals may perform fibrinolysis up to 6 h after symptom onset. In cases of stroke in the basilar artery, fibrinolysis may be performed even later after symptom onset. Intra-arterial fibrinolysis is performed in these cases using rt-PA or urokinase. Follow-up treatment of stroke patients should not only address post-stroke depression and neuropsychological deficits, but also include patient education about risk factors such as high blood pressure, diabetes mellitus, and cardiac arrhythmias.

    Full Text Available Abstract: Objective: Lacunar ischemic strokes comprise approximately 25% of all ischemic strokes. We compared the risk factors and clinical pattern of this type of stroke between males and females. Methods: This observational study involved 50 consecutive patients with their first-ever lacunar stroke and was conducted at the department of neurology of Sulaimaniya general teaching hospital, Iraq from December 1, 2010 to March 1, 2013. Patients’ risk factors, clinical presentation, and strokes’ patterns were noted and a comparison was made between males and females. Results: Males (64% outnumbered females (36% with a male to female ration of 1.7. The mean age of males was 63 years while it was 61 years in females. Although hypertension was more common in females than in males, diabetes and smoking were more common in the latter group; however, there were no statistically significant differences between the 2 genders in terms of hypertension (P-value <0.3 and diabetes (P-value < 0.07 while smoking was strongly associated with male gender (P-value<0.0001. Pure motor hemiparesis, ataxic hemiparesis, pure sensory stroke, and dysarthria-clumsy hand syndrome were more common in males; only senori-motor stroke revealed a statistically significant difference in favor males (P-value<0.0001; 95% CI -1.7 to 19.2. There was no statistically significant difference in terms of which side of the brain was infarcted between males and females (P-value<0.4. Conclusion: Males around the age of 63 years were the main target for these lacunar strokes. Cigarette smoking and sensorimotor strokes were significantly associated with male gender.

    Our purpose was to evaluate the safety and efficacy of endovascular treatment (EVT) of stroke caused by large vessel occlusions (LVO) performed by general interventional radiologists in cooperation with stroke neurologists and neuroradiologists at a center with a limited annual number of procedures. We aimed to compare our results with those previously reported from larger stroke centers. A total of 108 patients with acute stroke due to LVO treated with EVT were included. Outcome was measured using the modified Rankin scale (mRS) at 90 days. Efficacy was classified according to the modified thrombolysis in cerebral infarction (mTICI) scoring system. Safety was evaluated according to the incidence of procedural complications and symptomatic intracranial hemorrhage (sICH). Mean age of the patients was 67.5 years. The median National Institutes of Health Stroke Scale (NIHSS) on hospital admission was 17. Successful revascularization was achieved in 76%. 39.4% experienced a good clinical outcome (mRS<3). Intraprocedural complications were seen in 7.4%. 7.4% suffered a sICH. 21.3% died within 3 months after EVT. The use of general interventional radiologists in EVT of LVO may be a possible approach for improving EVT coverage where availability of specialized neurointerventionalists is challenging. EVT for LVO stroke performed by general interventional radiologists in close cooperation with diagnostic neuroradiologists and stroke neurologists can be safe and efficacious despite the low number of annual procedures.

    The nursing approach in the care of stroke patients has a direct impact on functional outcome. Nursing application of Bobath principles in stroke care offers a nursing focus on involvement of the affected side; facilitation of normal tone, posture, and movement; and development of more normal function. A research study evaluating the functional gains of stroke patients demonstrated a significant level of functional improvement in those treated with Bobath principles over stroke patients treated with the traditional nursing approach. Practical methods for applying Bobath principles in patient care activities are described. These therapeutic methods provide nurses with the means to maximize stroke patients' potential and further influence their functional recovery.

    Cor triatriatum sinistrum (CTS) is a congenital anomaly where the left atrium is divided into two compartments by a fibromuscular membrane. This report aims to add to the literature on a rare cardiac condition that can cause neurological morbidity. We report a case of a 19-year-old female with an infarct in the right middle cerebral artery (MCA) territory initially maintained on aspirin. Eighteen months later, she had recurrence of weakness, for which repeat transthoracic echocardiography (TTE) and re-evaluation of the first TTE demonstrated a hyperechoic membrane spanning the width of the left atrium, clinching the diagnosis of CTS. Despite anticoagulation with apixaban, she was admitted for a third stroke where she succumbed to hospital-acquired pneumonia. Among cases of CTS associated with stroke, anticoagulation and surgery were the main modes of treatment. This case has the longest follow-up and the first to demonstrate failure of antiplatelet therapy and anticoagulation. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    Full Text Available Background: S troke is the second commonest cause of death in India with crude overall prevalence rate of 220 per 100,000. With an increasing aging population at risk, the stroke burden in India can be expected to reach epidemic proportions. Materials and Methods: The first protocol-based prospective studies, funded by private agencies was conducted in Madras Institute of Neurology in 1984-86. The results led to establishment of the first stroke unit in Tamil Nadu state, in the institute. The first all-India hospital-based studies in acute stroke was completed as INDIAN COOPERATIVE ACUTE STROKE STUDIES (ICASS I and ICASS II with WHO STEP ONE by members of the Indian Stroke Association between 2000-2005. This has generated very useful data for our country. Results: Mortality in 1984-86 was 40%. Stroke unit in the institute dropped it to 12%. About 10 years later, ICASS studies showed a further fall of mortality to 8%, which is the current international figure in the west. Morbidity pattern showed about half return to their original activities. But about one third are left totally disabled needing prolonged care, for which fiscal, social and rehab provisions have to be done on a national basis. Conclusions: The progress and success of care of Stroke in the last three decades, from treatment in medical and neurology wards to specialized stroke units is presented. The main risk factors are hypertension, diabetes and ischemic heart disease across the country. Hypertension alone or with the other two diseases was present in 72% of cases. Prevention and treatment of these factors will reduce the stroke burden, mortality and morbidity of strokes. The Stroke-team concept can be extended to the smallest hospitals in our country.

    Full Text Available Background. Previous studies have suggested that black populations have more small-vessel and fewer cardioembolic strokes. We sought to analyze racial differences in ischemic stroke subtype employing a comprehensive diagnostic workup with magnetic resonance-imaging-(MRI- based evaluation including diffusion-weighted imaging (DWI. Methods. 350 acute ischemic stroke patients admitted to an urban hospital with standardized comprehensive diagnostic evaluations were retrospectively analyzed. Ischemic stroke subtype was determined by three Trial of Org 10172 in Acute Stroke Treatment (TOAST classification systems. Results. We found similar proportions of cardioembolic and lacunar strokes in the black and white cohort. The only subtype category with a significant difference by race was “stroke of other etiology,” more common in whites. Black stroke patients were more likely to have an incomplete evaluation, but this did not reach significance. Conclusions. We found similar proportions by race of cardioembolic and lacunar strokes when employing a full diagnostic evaluation including DWI MRI. The relatively high rate of cardioembolism may have been underappreciated in black stroke patients when employing a CT approach to stroke subtype diagnosis. Further research is required to better understand the racial differences in frequency of “stroke of other etiology” and explore disparities in the extent of diagnostic evaluations.

    The use of traditional Chinese medicine (TCM) in stroke is increasing worldwide. Here we report the existing clinical evidence of the Pinellia Ternata containing formula Wen Dan Decoction (WDD) for the treatment of ischemic stroke and hemorrhagic stroke. PubMed, CNKI, Wan Fang database, Cochrane Library and online Clinical Trial Registry were searched up to 26 February 2013 for randomized, controlled clinical trials (RCTs) using WDD as intervention versus Western conventional medicine as control to treat stroke. Clinical outcomes were improvement of the Neurological Functional Deficit Scores (NFDS) and overall therapeutic efficacy rates including rate of cure. Meta-regression analysis using Hedges'g was performed for RCTs with significant heterogeneity. A total of 22 RCTs of ischemic stroke and 4 RCTs of hemorrhagic stroke, involving 2214 patients (1167 used WDD), met our inclusion criteria. Meta-analysis of the 13 RCTs reporting NFDS improvement favored WDD over the control (mean difference=-3.40, 95% confidence intervals [CI]=[-4.64, -2.15]). Rate of overall therapeutic efficacy (odds ratio [OR]=3.39, 95%CI=[1.81, 6.37]) for hemorrhagic stroke were significantly higher in WDD treated patients than the control subjects. In the 1898 patients with ischemic stroke, WDD medication also achieved higher rates of cure (OR=2.22, 95%CI=[1.66, 2.97]) and overall therapeutic efficacy (OR=3.31, 95%CI=[2.54, 4.31]) than the conventional treatment. WDD displays benefits on improvement of neurological function and overall therapeutic efficacy in post-stroke patients. TCM such as WDD may serve as a therapeutic tool of dual actions to explore the common mechanisms underlying cerebral hemorrhage and ischemia. Copyright © 2015 Elsevier Ltd. All rights reserved.

  17. Emergency Medical Services Support for Acute Ischemic Stroke Patients Receiving Thrombolysis at a Primary Stroke Center

    2009-01-01

    Full Text Available Background Emergency Medical Services (EMS is a vital link in the overall chain of stroke survival. A Primary Stroke Center (PSC relies heavily on the 9-1-1 response system along with the ability of EMS personnel to accurately diagnose acute stroke. Other critical elements include identifying time of symptom onset, providing pre-hospital care, selecting a destination PSC, and communicating estimated time of arrival (ETA. Purpose Our purpose was to evaluate the EMS component of thrombolysed acute ischemic stroke patient care at our PSC. Methods In a retrospective manner we retrieved electronic copies of the EMS incident reports for every thrombolysed ischemic stroke patient treated at our PSC from September 2001 to August 2005. The following data elements were extracted: location of victim, EMS agency, times of dispatch, scene, departure, emergency department (ED arrival, recordings of time of stroke onset, blood pressure (BP, heart rate (HR, cardiac rhythm, blood glucose (BG, Glasgow Coma Scale (GCS, Cincinnati Stroke Scale (CSS elements, emergency medical personnel field assessment, and transport decision making. Results Eighty acute ischemic stroke patients received thrombolysis during the study interval. Eighty-one percent arrived by EMS. Two EMS agencies transported to our PSC. Mean dispatch-to-scene time was 6 min, on-scene time was 16 min, transport time was 10 min. Stroke onset time was recorded in 68%, BP, HR, and cardiac rhythm each in 100%, BG in 81%, GCS in 100%, CSS in 100%, and acute stroke diagnosis was made in 88%. Various diagnostic terms were employed: cerebrovascular accident in 40%, unilateral weakness or numbness in 20%, loss of consciousness in 16%, stroke in 8%, other stroke terms in 4%. In 87% of incident reports there was documentation of decision-making to transport to the nearest PSC in conjunction with pre-notification. Conclusion The EMS component of thrombolysed acute ischemic stroke patients care at our PSC appeared

    Yeu-Sheng Tyan

    2014-01-01

    Full Text Available We propose an ischemic stroke detection system with a computer-aided diagnostic ability using a four-step unsupervised feature perception enhancement method. In the first step, known as preprocessing, we use a cubic curve contrast enhancement method to enhance image contrast. In the second step, we use a series of methods to extract the brain tissue image area identified during preprocessing. To detect abnormal regions in the brain images, we propose using an unsupervised region growing algorithm to segment the brain tissue area. The brain is centered on a horizontal line and the white matter of the brain’s inner ring is split into eight regions. In the third step, we use a coinciding regional location method to find the hybrid area of locations where a stroke may have occurred in each cerebral hemisphere. Finally, we make corrections and mark the stroke area with red color. In the experiment, we tested the system on 90 computed tomography (CT images from 26 patients, and, with the assistance of two radiologists, we proved that our proposed system has computer-aided diagnostic capabilities. Our results show an increased stroke diagnosis sensitivity of 83% in comparison to 31% when radiologists use conventional diagnostic images.

    Research works were done on origin and development of the denomination, the acute stage of etiopathogenisis and pathogenesis, therapeutical priniciple and therapeutical methods in hemorrhagic stroke. Stroke was divided into is chemic and hemorrhagic until the end of the Qing dynasty. In 1997, Terminology of Traditional Chinese Medicine Treatment-Disease Part of National Standard formally included the term hemorrhagic stroke. Before 1950s-1960s, the pathogenesis emphasizes the up-stirring of liver, the adverse-rising of both blood and qi. A proper remedy should to subdue the liver yang, calm down the endopathic wind and clear heat. Since 1970s, it has been considered that the disorder is closely related with the spleen and stomach. The focal pathogenesis was blocked passage of the middle jiao, disorder of qi in ascending and descending and the abnormal flow of qi and blood. Since 1980s, it was claimed that hemorrhagic stroke belongs to blood syndrome of TCM. The vital pathogenesis was accumulation of blood stasis in acute stage of hemorrhagic stroke. The key point of therapeutical method was to promote blood circulation to remove blood stasis. In recent years, the theories of endogenous toxic factor, consumption, yin and yang syndrome, and the therapeutical method of antidote, assisting the vital qi, especially the development of common therapeutical methods were developed, with an abundance of differential diagnosis and treatment in hemorrhagic stroke.

    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.

    2012-09-27

    Despite advances in the acute management of stroke, a large proportion of stroke patients are left with significant impairments. Over the coming decades the prevalence of stroke-related disability is expected to increase worldwide and this will impact greatly on families, healthcare systems and economies. Effective neuro-rehabilitation is a key factor in reducing disability after stroke. In this review, we discuss the effects of stroke, principles of stroke rehabilitative care and predictors of recovery. We also discuss novel therapies in stroke rehabilitation, including non-invasive brain stimulation, robotics and pharmacological augmentation. Many trials are currently underway, which, in time, may impact on future rehabilitative practice.

    All stroke patients should receive the same degree of specialized healthcare attention according to the stage of their disease, independently of where they live, their age, gender or ethnicity. To create an organized healthcare system able to offer the needed care for each patient, optimizing the use of the existing resource. A committee of 14 neurologists specialized in neurovascular diseases representing different regions of Spain evaluated the available scientific evidence according to the published literature. During the acute phase, all stroke patients must be evaluated in hospitals that offer access to specialized physicians (neurologists) and the indicated diagnostic and therapeutic procedures. Hospitals that deliver care to acute stroke patients must be prepared to attend these patients and need to arrange a predefined transferring circuit coordinated with the extrahospitalary emergency service. Since resources are limited, they should be structured into different care levels according to the target population. Thus, three types of hospitals will be defined for stroke care: reference stroke hospital, hospital with stroke unit, hospital with stroke team.

    2007-10-01

    Full Text Available Abstract Background Neuroserpin, primarily localized to CNS neurons, inhibits the adverse effects of tissue-type plasminogen activator (tPA on the neurovascular unit and has neuroprotective effects in animal models of ischemic stroke. We sought to evaluate the association of neuroserpin polymorphisms with risk for ischemic stroke among young women. Methods A population-based case-control study of stroke among women aged 15–49 identified 224 cases of first ischemic stroke (47.3% African-American and 211 age-matched control subjects (43.1% African-American. Neuroserpin single nucleotide polymorphisms (SNPs chosen through HapMap were genotyped in the study population and assessed for association with stroke. Results Of the five SNPs analyzed, the A allele (frequency; Caucasian = 0.56, African-American = 0.42 of SNP rs6797312 located in intron 1 was associated with stroke in an age-adjusted dominant model (AA and AT vs. TT among Caucasians (OR = 2.05, p = 0.023 but not African-Americans (OR = 0.71, p = 0.387. Models adjusting for other risk factors strengthened the association. Race-specific haplotype analyses, inclusive of SNP rs6797312, again demonstrated significant associations with stroke among Caucasians only. Conclusion This study provides the first evidence that neuroserpin is associated with early-onset ischemic stroke among Caucasian women.

    2014-05-01

    Full Text Available This study aimed to review published literature concerning the major changes that occur in the respiratory system after stroke, and also the impact of respiratory muscle training in these patients. The literature search was conducted through electronic databases (PubMed, SciELO and Pedro in Portuguese and English languages on themes related to changes in the respiratory system and methods of assessment and rehabilitation of respiratory muscle strength in individuals affected by stroke. There is scientific evidence that individuals affected by stroke may show decreased inspiratory and expiratory muscle strength. Studies suggest that respiratory muscle training through threshold load can bring benefits by improving respiratory function and respiratory muscle strength. However, more studies should be conducted to deepen the knowledge about the benefits and long-term effects of pulmonary rehabilitation in patients with stroke.

    Full Text Available Dževdet Smajlović Department of Neurology, University Clinical Centre Tuzla, School of Medicine, University of Tuzla, Bosnia and Herzegovina Abstract: Strokes in young adults are reported as being uncommon, comprising 10%–15% of all stroke patients. However, compared with stroke in older adults, stroke in the young has a disproportionately large economic impact by leaving victims disabled before their most productive years. Recent publications report an increased incidence of stroke in young adults. This is important given the fact that younger stroke patients have a clearly increased risk of death compared with the general population. The prevalence of standard modifiable vascular risk factors in young stroke patients is different from that in older patients. Modifiable risk factors for stroke, such as dyslipidemia, smoking, and hypertension, are highly prevalent in the young stroke population, with no significant difference in geographic, climatic, nutritional, lifestyle, or genetic diversity. The list of potential stroke etiologies among young adults is extensive. Strokes of undetermined and of other determined etiology are the most common types among young patients according to TOAST (Trial of Org 10172 in Acute Stroke Treatment criteria. Prevention is the primary treatment strategy aimed at reducing morbidity and mortality related to stroke. Therefore, primary prevention is very important with regard to stroke in young adults, and aggressive treatment of risk factors for stroke, such as hypertension, smoking, and dyslipidemia, is essential. The best form of secondary stroke prevention is directed toward stroke etiology as well as treatment of additional risk factors. However, there is a lack of specific recommendations and guidelines for stroke management in young adults. In conclusion, strokes in young adults are a major public health problem and further research, with standardized methodology, is needed in order to give us more

    Background The PRE-hospital Stroke Treatment Organization was formed in 2016 as an international consortium of medical practitioners involved in pre-hospital treatment of patients with acute stroke. Aims PRE-hospital Stroke Treatment Organization's mission is to improve stroke outcomes by supporting research and advocacy for pre-hospital stroke treatment in Mobile Stroke Units. PRE-hospital Stroke Treatment Organization will provide a platform to enhance collaborative research across the spectrum of acute stroke management in the pre-hospital setting. PRE-hospital Stroke Treatment Organization will also facilitate the appropriate proliferation and distribution of Mobile Stroke Units by providing a forum for professional communication, resource for public education, and stimulus for government, industry, and philanthropic support. Summary of review In this "white paper", we describe the evidence supporting pre-hospital stroke treatment, progress to date, practical issues such as application in various environments and staffing, planned research initiatives, and organizational structure. Conclusions PRE-hospital Stroke Treatment Organization is not-for-profit, with membership open to anyone involved (or hoping to become involved) in pre-hospital stroke care. PRE-hospital Stroke Treatment Organization has a Steering Committee comprised of members from Europe, U.S., Canada, Australia, and other regions having a Mobile Stroke Unit in operation. PRE-hospital Stroke Treatment Organization convenes satellite meetings for membership at the International Stroke Conference and European Stroke Congress each year to address the PRE-hospital Stroke Treatment Organization mission. The first research collaborations agreed upon are to: (1) develop a list of common data elements to be collected by all Mobile Stroke Unit programs and entered into a common research database, and (2) develop a protocol for investigating the natural history of hyper-acute Intracerebral Hemorrhage.

    Full Text Available Objective. The aim of this exploratory pilot study is to test the effects of bilateral tDCS combined with upper extremity robot-assisted therapy (RAT on stroke survivors. Methods. We enrolled 23 subjects who were allocated to 2 groups: RAT + real tDCS and RAT + sham-tDCS. Each patient underwent 10 sessions (5 sessions/week over two weeks. Outcome measures were collected before and after treatment: (i Fugl-Meyer Assessment-Upper Extremity (FMA-UE, (ii Box and Block Test (BBT, and (iii Motor Activity Log (MAL. Results. Both groups reported a significant improvement in FMA-UE score after treatment (p<0.01. No significant between-groups differences were found in motor function. However, when the analysis was adjusted for stroke type and duration, a significant interaction effect (p<0.05 was detected, showing that stroke duration (acute versus chronic and type (cortical versus subcortical modify the effect of tDCS and robotics on motor function. Patients with chronic and subcortical stroke benefited more from the treatments than patients with acute and cortical stroke, who presented very small changes. Conclusion. The additional use of bilateral tDCS to RAT seems to have a significant beneficial effect depending on the duration and type of stroke. These results should be verified by additional confirmatory studies.

  2. [Post-stroke apathy].

    Science.gov (United States)

    López-Dóriga Bonnardeaux, Pedro; Andrino Díaz, Nuria

    2016-01-01

    Apathy is a motivational disturbance that can be defined as a quantitative reduction of goal-directed behaviour. Patients present with loss of motivation, concern, interest, and emotional response, resulting in a loss of initiative, decreased interaction with their environment, and a reduced interest in social life. Apathy not only appears to be common in stroke patients, but it has also been related to a wide range of negative consequences for the patients and their caregivers, including poor functional recovery, loss of social independence, and caregiver distress. Clear definition and consensus diagnostic criteria for apathy are needed to accomplish an accurate assessment and an individualised treatment plan. Although there have been reports of successful behavioural therapy treatment of apathetic states, there is a paucity of controlled clinical trials on the efficacy of apathetic behaviours using pharmacotherapy.

    Limited population-based data exist on differences in the incidence of major pathological stroke types and ischaemic stroke subtypes across ethnic groups. We aimed to provide such data within the large multi-ethnic population of Auckland, New Zealand. All first-ever cases of stroke (n=1423) in a population-based register in 940 000 residents (aged 15 years) in Auckland, New Zealand, for a 12-month period in 2002-2003, were classified into ischaemic stroke, primary intracerebral haemorrhage (PICH), subarachnoid haemorrhage, and undetermined stroke, according to standard definitions and results of neuroimaging/necropsy (in over 90% of cases). Ischaemic stroke was further classified into five subtypes. Ethnicity was self-identified and grouped as New Zealand (NZ)/European, Maori/Pacific, and Asian/other. Incidence rates were standardised to the WHO world population by the direct method, and differences in rates between ethnic groups expressed as rate ratios (RRs), with NZ/European as the reference group. In NZ/European people, ischaemic stroke comprised 73%, PICH 11%, and subarachnoid haemorrhage 6%, but PICH was higher in Maori/Pacific people (17%) and in Asian/other people (22%). Compared with NZ/European people, age-adjusted RRs for PICH were 2.7 (95% CI 1.8-4.0) and 2.3 (95% CI 1.4-3.7) among Maori/Pacific and Asian/other people, respectively. The corresponding RR for ischaemic stroke was greater for Maori/Pacific people (1.7 [95% CI 1.4-2.0]), particularly embolic stroke, and for Asian/other people (1.3 [95% CI 1.0-1.7]). The onset of stroke in Maori/Pacific and Asian/other people began at significantly younger ages (62 years and 64 years, respectively) than in NZ/Europeans (75 years; p<0.0001). There were ethnic differences in the risk factor profiles (such as age, sex, hypertension, cardiac disease, diabetes, hypercholesterolaemia, smoking status, overweight) for the stroke types and subtypes. Compared to NZ/Europeans, Maori/Pacific and Asian/other people are

    Full Text Available Abstract Background Recent trials suggest that angiotensin-converting enzyme inhibitors (ACEI are effective in prevention of ischemic stroke, as measured by reduced stroke incidence. We aimed to compare stroke severity between stroke patients who were taking ACEI before their stroke onset and those who were not, to examine the effects of pretreatment with ACEI on ischemic stroke severity. Methods We retrospectively studied 126 consecutive patients presenting within 24 hours of ischemic stroke onset, as confirmed by diffusion-weighted magnetic resonance imaging (DWI. We calculated the NIHSS score at presentation, as the primary measure of clinical stroke severity, and categorized stroke severity as mild (NIHSS [less than or equal to] 7, moderate (NIHSS 8–13 or severe (NIHSS [greater than or equal to] 14. We analyzed demographic data, risk-factor profile, blood pressure (BP and medications on admissions, and determined stroke mechanism according to TOAST criteria. We also measured the volumes of admission diffusion- and perfusion-weighted (DWI /PWI magnetic resonance imaging lesions, as a secondary measure of ischemic tissue volume. We compared these variables among patients on ACEI and those who were not. Results Thirty- three patients (26% were on ACE-inhibitors. The overall median baseline NIHSS score was 5.5 (range 2–21 among ACEI-treated patients vs. 9 (range 1–36 in non-ACEI patients (p = 0.036. Patients on ACEI prior to their stroke had more mild and less severe strokes, and smaller DWI and PWI lesion volumes compared to non-ACEI treated patients. However, none of these differences were significant. Predictably, a higher percentage of patients on ACEI had a history of heart failure (p = 0.03. Age, time-to-imaging or neurological evaluation, risk-factor profile, concomitant therapy with lipid lowering, other antihypertensives or antithrombotic agents, or admission BP were comparable between the two groups. Conclusion Our results

    Chronic hypoperfusion from athero-stenotic lesions is thought to lead to better collateral recruitment compared to cardioembolic strokes. It was sought to compare collateral flow in stroke patients with atrial fibrillation (AF) versus stroke patients with cervical atherosclerotic steno-occlusive disease (CASOD). This was a retrospective review of a prospectively collected endovascular database. Patients with (i) anterior circulation large vessel occlusion stroke, (ii) pre-treatment computed tomography angiography (CTA) and (iii) intracranial embolism from AF or CASOD were included. CTA collateral patterns were evaluated and categorized into two groups: absent/poor collaterals (CTA collateral score 0-1) versus moderate/good collaterals (CTA collateral score 2-4). CT perfusion was also utilized for baseline core volume and evaluation of infarct growth. A total of 122 patients fitted the inclusion criteria, of whom 88 (72%) had AF and 34 (27%) CASOD. Patients with AF were older (P Collateral scores were lower in the AF group (P = 0.01) with patients having poor collaterals in 28% of cases versus 9% in the CASOD group (P = 0.03). Mortality rates (20% vs. 0%; P = 0.02) were higher in the AF patients whilst rates of any parenchymal hemorrhage (6% vs. 26%; P collaterals (odds ratio 4.70; 95% confidence interval 1.17-18.79; P = 0.03). Atheroembolic strokes seem to be associated with better collateral flow compared to cardioembolic strokes. This may in part explain the worse outcomes of AF-related stroke. © 2017 EAN.

    Little is known of the impact of stroke laterality on the management process and outcome of patients with acute ischemic stroke (AIS). Consecutive patients admitted to a general hospital over 1 year with supratentorial AIS were eligible for inclusion in the study. Baseline characteristics and risk factors, delays in hospital admission, imaging, intrahospital transfer to an acute stoke unit, stroke severity and classification, length of hospital admission, as well as 10-year mortality were measured and compared among right and left hemisphere AIS patients. There were 141 patients (77 men, 64 women; median age 73 [interquartile range 63-79] years), There were 71 patients with left hemisphere AIS and 70 with right hemisphere AIS. Delays to hospital admission from stroke onset to neuroimaging were similar among right and left hemisphere AIS patients. Delay in transfer to an acute stroke unit (ASU) following hospital admission was on average 14 hours more for right hemisphere compared to left hemisphere AIS patients (P = .01). Laterality was not associated with any difference in 10-year survival. Patients with mild and nondominant AIS merit particular attention to minimize their intrahospital transfer time to an ASU.

    Full Text Available Context: With advances in neuroimaging, traditional views regarding the clinicoanatomic correlation in stroke patients with aphasia are being challenged and it has been observed that lesions at a given cortical or subcortical site may manifest with different aphasia profiles. Aims: To study as to whether there is a strict clinicoanatomical correlation between the type of aphasia and lesion site in patients with first ever stroke. Settings and Design: Observational study, based in a tertiary care center. Materials and Methods: Stroke patient′s ≥18 years of age were screened and those with first ever stroke and aphasia were subjected to a detailed stroke workup and language assessment using the Hindi version of Western Aphasia Battery (WAB. Statistical analysis was done with χ2 test with Yates correction and Kruskal-Wallis test. The level of significance was set at P < 0.05. Results: Overall aphasia was detected in 27.9% of the 260 screened cases with stroke. Amongst 60 cases with first ever stroke and aphasia, the aphasia type was: Global (33.33%, Broca′s (28.3%, transcortical motor (13.33%, transcortical sensory (10%, Wernicke′s (8.33%, anomic (5%, and conduction (1.67% aphasia. A definite correlation between the lesion site and the type of aphasia as per the traditional classification was observed in 35% cases only. Conclusions: No absolute correlation exists between the lesion site and the type of clinical aphasia syndrome in majority of the patients with cortical and subcortical stroke.

    Full Text Available Background. Stroke can be a challenging diagnosis in an emergency-setting. We sought to determine whether copeptin may be a useful biomarker to differentiate between ischemic stroke (IS, transient ischemic attack (TIA, and stroke-mimics. Methods. In patients with suspected stroke arriving within 4.5 hours of symptom-onset, copeptin-levels were measured in initial blood-samples. The final diagnosis was adjudicated by vascular neurologists blinded to copeptin-values. Results. Of all 36 patients with available copeptin-values (median age 71 years, IQR: 54–76; 44% female, 20 patients (56% were diagnosed with IS, no patient was diagnosed with hemorrhagic stroke, nine patients (25% were diagnosed with TIA, and seven patients (19% were stroke-mimics. Copeptin-levels (in pmol/L tended to be higher in patients with IS [19.1 (11.2–48.5] compared to TIA [9.4 (5.4–13.8]. In stroke-mimics the range of values was extremely broad [33.3 (7.57–255.7]. The diagnostic accuracy of copeptin for IS was 63% with a sensitivity of 80% and a positive predictive value of 64%. Conclusion. In this cohort of patients copeptin-levels within 4.5 hours of symptom onset were higher in patients with IS compared to TIA but the broad range of values in stroke-mimics limits diagnostic accuracy. This trial is registered with UTN: U1111-1119-7602.

    Full Text Available Objectives: To evaluate (1 the prevalence of operationally defined depressive disorder (ICD-10 in chronic stroke subjects and (2 the relationship of post-stroke depression (PSD with disability. Design: Cross-sectional, descriptive study. Setting: Neurological rehabilitation unit of a tertiary care university research center. Materials and Methods: Participants were those with first episode of supratentorial stroke of more than 3 months′ duration with impaired balance and gait who had been referred for rehabilitation. Data were collected on demographic data, stroke data (side and type of lesion and post-stroke duration, cognition (mini mental state examination, depressive ideation (Hamilton Depression Rating Scale - HRDS, impairment (Scandinavian Stroke Scale, balance (Berg Balance Scale, ambulatory status (Functional Ambulation Category, walking ability (speed, and independence in activities of daily living (Barthel Index. Statistical analysis was done using SPSS 13.0. We carried out the chi-square test for ordinal variables and the independent t test for continuous variables. Results: Fifty-one patients (M:F: 41:10 of mean age 46.06 ± 11.19 years and mean post-stroke duration of 467.33 ± 436.39 days were included in the study. Eighteen of the 51 participants (35.29% met the criteria for depression. Demographic variables like male gender, being married, living in a nuclear family, urban background, and higher HRDS score were significantly correlated with PSD (P < 0.05. Depression was related to functional disability after stroke but to a statistically insignificant level (P > 0.05 and was unrelated to lesion-related parameters. Conclusion: Depression occurs in one-third of chronic stroke survivors and is prevalent in subjects referred for rehabilitation. PSD is related primarily to demographic variables and only to a lesser extent to functional disability following stroke.

    To describe the systematic development of the Stroke Coach, a theory- and evidence-based intervention to improve control of lifestyle behavior risk factors in patients with stroke. Intervention development. Community. Individuals who have had a stroke. We used intervention mapping to guide the development of the Stroke Coach. Intervention mapping is a systematic process used for intervention development and composed of steps that progress from the integration of theory and evidence to the organization of realistic strategies to facilitate the development of a practical intervention supported by empirical evidence. Social cognitive theory was the underlying premise for behavior change, whereas control theory methods were directed toward sustaining the changes to ensure long-term health benefits. Practical evidence-based strategies were linked to behavioral determinants to improve stroke risk factor control. Not applicable. The Stroke Coach is a patient-centered, community-based, telehealth intervention to promote healthy lifestyles after stroke. Over 6 months, participants receive seven 30- to 60-minute telephone sessions with a lifestyle coach who provides education, facilitates motivation for lifestyle modification, and empowers participants to self-management their stroke risk factors. Participants also receive a self-management manual and a self-monitoring kit. Through the use of intervention mapping, we developed a theoretically sound and evidence-grounded intervention to improve risk factor control in patients with stroke. If empirical evaluation of the Stroke Coach produces positive results, the next step will be to develop an implementation intervention to ensure successful uptake and delivery of the program in community and outpatient settings.

    Full Text Available Introduction: Biological, physical and phsycosocial changes in stroke patient could be a stressor that induced a depression state. There would be an emotional disturbance in stroke patient and stroke attack would be recurrent, if it was not treated. One of the alternative techniques to reduce depression is musical therapy especially memory songs. Method: This study was used a quasy experimental pre-post test purposive sampling design. The population was stroke patients who treated in Neurological Ward A and Stroke Unit Dr Soetomo Hospital Surabaya. There were 12 respondents divided into 6 respondents for treatment group and 6 respondents for control group. The independent variable was music (memory song and dependent variable was depression. Data were collected by using questionnaire which adapted from Hamilton Depression Rating Scale and Geriatric Depression Rating Scale, then analyzed by using Wilcoxon Signed Rank Test and Mann Whitney U Test with significance level α≤0.05. Result: The result showed that there was a difference between pre test and post test in depression (p=0.0196 and there was a difference in the depression between treatment group and control group (p=0.002. Discussion: It can be concluded that music (memory songs has an effect to the depression of stroke patient. Further studies are needed to concerning other factors that may affect the relaxation technique especially in listening music.

    Background: Stroke is a common neurological disease that results in significant mortality and morbidity globally. Several risk factors have been identified for stroke among which hyperlipidaemia is one of the modifiable risk factors. Recent clinical trials have shown a reduction in ischemic stroke for patients taking lipid lowering medications. Therefore, the aim of this study was to find out the frequency of hypercholesterolemia in patients of ischemic stroke in Hazara region. Method: This cross sectional study was carried out in the Medical Department of Ayub Teaching Hospital, Abbottabad. Ninety patients of stroke confirmed as ischemic by CT scan brain were enrolled in the study after informed consent. The frequency of hypercholesterolemia in patients was recorded. Results: There were 55 (61.1 percentage) males. The mean age of patients was 64.4±11.5 years. The mean serum cholesterol in all patients was 4.16±1.1 mmol/l. The mean serum cholesterol of male patients was 4.3±1.2 mmol/l and 4.0±10.9 mmol/l in the case of females. Conclusions: Hypercholesterolemia could not be established as a major risk factor for stroke in our setup through this study that allude to the fact that other risk factors might be contributing more to the incidence of cerebrovascular accident in our population.

    2015-01-01

    Post-stroke depression (PSD) is the most common mood disorder following a stroke, and also the main factor limiting recovery and rehabilitation in stroke patients. In addition, it may increase mortality by up to ten times. PSD occurs in 1 in 3 stroke patients and more than half of all cases are neither diagnosed nor treated. Several mechanisms, including biological, behavioral, and social factors, are involved in its pathogenesis. Symptoms usually occur within the first three months after stroke (early onset PSD), and less frequently at a later time (late onset PSD). Symptoms resemble those of other types of depression, although there are some differences: PSD patients experience more sleep disturbances, vegetative symptoms, and social withdrawal. For PSD diagnosis, we recommended vigilance and use of specific diagnostic tools such as the Patient Health Questionnaire-2 (PHQ-2). The treatments of choice are selective serotonin reuptake inhibitors (SSRI). However, there are still many unanswered questions in the treatment of PSD, such as the best time to start treatment or the effects of antidepressants on cognition and motor function, among others. Neurologists play a pivotal role in the care and management of patients recovering from stroke. They must be familiar with methods for early detection and treatment of PSD, as this can facilitate a patient's functional recovery and social reintegration, and improve quality of life for patients and their families.

    2017-02-01

    Full Text Available Stroke is the third leading cause of death. The role of genetics in the etiology and development of this disease is undeniable. As a result of inadequate previous research, more and more studies in the field of genetics are necessary to identify pathways involved in the pathogenesis of stroke, which in turn, may lead to new therapeutic approaches. However, due to the multifactorial nature of stroke and the few studies conducted in this field, genetic diversity is able to predict only a small fraction of the risk of disease. On the other hand, studies have shown genetically different architecture for different types of stroke, and finally pharmacogenomics as an important part of personalized medicine approach, is influenced by genetic studies, all of which confirm the need of addressing the topic by researchers.

    Blood glucose is often elevated in acute stroke, and higher admission glucose levels are associated with larger lesions, greater mortality and poorer functional outcome. In patients treated with thrombolysis, hyperglycemia is associated with an increased risk of hemorrhagic transformation...... of infarcts. For a number of years, tight glycemic control has been regarded as beneficial in critically illness, but recent research has been unable to support this notion. The only completed randomized study on glucose-lowering therapy in stroke has failed to demonstrate effect, and concerns relating...... to the risk of inducing potentially harmful hypoglycemia has been raised. Still, basic and observational research is overwhelmingly in support of a causal relationship between blood glucose and stroke outcome and further research on glucose-lowering therapy in acute stroke is highly warranted....

    stroke is a national research priority. However, in the literature there is still minimal systematic investigation of stroke nursing - especially practice. The aim of this study was to explore stroke nurses' research priorities through a series of focus groups. the study was qualitative and involved focus groups (n = 7) with registered nurses working in stroke care settings and who were members of the Scottish Stroke Nurses Forum. Data were analysed to identify conceptual categories, which were found to relate to the categories defined by Kirkevold (1997) and Booth (2001). five priority areas for stroke nursing were described: preventive/conserving; supporting/consoling; restorative; integrative; and service structure/systems. by consulting stroke nurses it can be ensured that future research truly reflects the nature of nursing care and is of particular relevance to stroke nursing practice. The development of research evidence-base in stroke nursing will lead to increased knowledge, a better quality of care and ultimately better outcomes for patients.

    Epidemiological and family studies have provided evidence on the role of genetic factors in stroke, particularly in stroke occurring at young age. However, despite its impact, young stroke continues to be understudied. This article reviews the existing literature on the most investigated monogenic disorders (CADASIL, Fabry disease, MELAS, RVCL, COL4A1, Marfan and Ehlers-Danlos syndromes) causing stroke in young and a number of candidate genes associated with stroke occurring in patients younger than 50 years. Although our study failed in identifying strong and reliable associations between specific genes and young stroke, our detailed literature revision on the field allowed us to compile a panel of genes possibly generating a susceptibility to stroke, which could be a starting point for future research. Since stroke is a potentially preventable disease, the identification of genes associated with young stroke may promote novel prevention strategies and allow the identification of therapeutic disease targets.

  7. Can the FAST and ROSIER adult stroke recognition tools be applied to confirmed childhood arterial ischemic stroke?

    2011-10-01

    Full Text Available Abstract Background Stroke recognition tools have been shown to improve diagnostic accuracy in adults. Development of a similar tool in children is needed to reduce lag time to diagnosis. A critical first step is to determine whether adult stoke scales can be applied in childhood stroke. Our objective was to assess the applicability of adult stroke scales in childhood arterial ischemic stroke (AIS Methods Children aged 1 month to Results 47 children with AIS were identified. 34 had anterior, 12 had posterior and 1 child had anterior and posterior circulation infarcts. Median age was 9 years and 51% were male. Median time from symptom onset to ED presentation was 21 hours but one third of children presented within 6 hours. The most common presenting stroke symptoms were arm (63%, face (62%, leg weakness (57%, speech disturbance (46% and headache (46%. The most common signs were arm (61%, face (70% or leg weakness (57% and dysarthria (34%. 36 (78% of children had at least one positive variable on FAST and 38 (81% had a positive score of ≥1 on the ROSIER scale. Positive scores were less likely in children with posterior circulation stroke. Conclusion The presenting features of pediatric stroke appear similar to adult strokes. Two adult stroke recognition tools have fair to good sensitivity in radiologically confirmed childhood AIS but require further development and modification. Specificity of the tools also needs to be determined in a prospective cohort of children with stroke and non-stroke brain attacks.

They are the compression-combustion-expansion (high pressure loop) and the exhaust-intake (low pressure or gas exchange loop) parts. The main reason for efficiency decrease at part load conditions for these types of engines is the flow restriction at the cross sectional area of the intake system by partially closing the throttle valve, which leads to increased pumping losses and to increased low pressure loop area on the p-V diagram. Meanwhile, the poorer combustion quality, i.e. lower combustion speed and cycle to cycle variations, additionally influence these pressure loop areas. In this study, methods for increasing efficiency at part load conditions and their potential for practical use are investigated. The study also includes a review of the vast literature on the solution of this problem. This investigation shows that the potential for increasing the efficiency of SI engines at part load conditions is not yet exhausted. Each method has its own advantages and disadvantages. Among these, the most promising methods to decrease the fuel consumption at part load conditions are stratified charge and variable displacement engines. When used in combination, the other listed methods are more effective than their usage alone

    The global burden of ischaemic strokes is almost 4-fold greater than haemorrhagic strokes. Current evidence suggests that 25–30% of ischaemic stroke survivors develop immediate or delayed vascular cognitive impairment (VCI) or vascular dementia (VaD). Dementia after stroke injury may encompass all types of cognitive disorders. States of cognitive dysfunction before the index stroke are described under the umbrella of pre-stroke dementia, which may entail vascular changes as well as insidious neurodegenerative processes. Risk factors for cognitive impairment and dementia after stroke are multifactorial including older age, family history, genetic variants, low educational status, vascular comorbidities, prior transient ischaemic attack or recurrent stroke and depressive illness. Neuroimaging determinants of dementia after stroke comprise silent brain infarcts, white matter changes, lacunar infarcts and medial temporal lobe atrophy. Until recently, the neuropathology of dementia after stroke was poorly defined. Most of post-stroke dementia is consistent with VaD involving multiple substrates. Microinfarction, microvascular changes related to blood–brain barrier damage, focal neuronal atrophy and low burden of co-existing neurodegenerative pathology appear key substrates of dementia after stroke injury. The elucidation of mechanisms of dementia after stroke injury will enable establishment of effective strategy for symptomatic relief and prevention. Controlling vascular disease risk factors is essential to reduce the burden of cognitive dysfunction after stroke.

    Stroke is a heterogeneous syndrome, and determining risk factors and treatment depends on the specific pathogenesis of stroke. Risk factors for stroke can be categorized as modifiable and nonmodifiable. Age, sex, and race/ethnicity are nonmodifiable risk factors for both ischemic and hemorrhagic stroke, while hypertension, smoking, diet, and physical inactivity are among some of the more commonly reported modifiable risk factors. More recently described risk factors and triggers of stroke include inflammatory disorders, infection, pollution, and cardiac atrial disorders independent of atrial fibrillation. Single-gene disorders may cause rare, hereditary disorders for which stroke is a primary manifestation. Recent research also suggests that common and rare genetic polymorphisms can influence risk of more common causes of stroke, due to both other risk factors and specific stroke mechanisms, such as atrial fibrillation. Genetic factors, particularly those with environmental interactions, may be more modifiable than previously recognized. Stroke prevention has generally focused on modifiable risk factors. Lifestyle and behavioral modification, such as dietary changes or smoking cessation, not only reduces stroke risk, but also reduces the risk of other cardiovascular diseases. Other prevention strategies include identifying and treating medical conditions, such as hypertension and diabetes, that increase stroke risk. Recent research into risk factors and genetics of stroke has not only identified those at risk for stroke but also identified ways to target at-risk populations for stroke prevention. © 2017 American Heart Association, Inc.

    Soluble corin was decreased in coronary heart disease. Given the connections between cardiac dysfunction and stroke, circulating corin might be a candidate marker of stroke risk. However, the association between circulating corin and stroke has not yet been studied in humans. Here, we aimed to examine the association in patients wtith stroke and community-based healthy controls. Four hundred eighty-one patients with ischemic stroke, 116 patients with hemorrhagic stroke, and 2498 healthy controls were studied. Serum soluble corin and some conventional risk factors of stroke were examined. Because circulating corin was reported to be varied between men and women, the association between serum soluble corin and stroke was evaluated in men and women, respectively. Patients with ischemic and hemorrhagic stroke had a significantly lower level of serum soluble corin than healthy controls in men and women (all P values, stroke than men in the highest quartile. Women in the lowest quartile of serum soluble corin were also more likely to have ischemic (OR, 3.10; 95% confidence interval, 1.76-5.44) and hemorrhagic (OR, 8.54; 95% confidence interval, 2.35-31.02) stroke than women in the highest quartile. ORs of ischemic and hemorrhagic stroke were significantly increased with the decreasing levels of serum soluble corin in men and women (all P values for trend, stroke compared with healthy controls. Our findings raise the possibility that serum soluble corin may have a pathogenic role in stroke. © 2015 American Heart Association, Inc.

    Quantitative videodensitometry was studied with a view to its possible application as a new, non-invasive method of measuring cardiac stroke volume. To begin with, the accuracy of roentgen volumetric measurements was determined. After this, blood volume variations were measured by densitometry in five animal experiments. The findings were compared with the volumes measured by a flowmeter in the pulmonary artery. The total stroke volume was found to be proportional to the difference between the maximum and mean densitometric volume. A comparison between videodensitometry and other non-invasive methods showed that, in a stable circulatory system, the results of videodensitometry are equally reliable as, or even more reliable than, those of the conventional methods.

    Full Text Available Abstract Background Stroke is the third leading cause of death in developed countries and the leading cause of long-term disability worldwide. A series of national stroke audits in the UK highlighted the differences in stroke care between hospitals. The study aims to describe variation in outcomes following stroke and to identify the characteristics of services that are associated with better outcomes, after accounting for case mix differences and individual prognostic factors. Methods/Design We will conduct a cohort study in eight acute NHS trusts within East of England, with at least one year of follow-up after stroke. The study population will be a systematically selected representative sample of patients admitted with stroke during the study period, recruited within each hospital. We will collect individual patient data on prognostic characteristics, health care received, outcomes and costs of care and we will also record relevant characteristics of each provider organisation. The determinants of one year outcome including patient reported outcome will be assessed statistically with proportional hazards regression models. Self (or proxy completed EuroQol (EQ-5D questionnaires will measure quality of life at baseline and follow-up for cost utility analyses. Discussion This study will provide observational data about health service factors associated with variations in patient outcomes and health care costs following hospital admission for acute stroke. This will form the basis for future RCTs by identifying promising health service interventions, assessing the feasibility of recruiting and following up trial patients, and provide evidence about frequency and variances in outcomes, and intra-cluster correlation of outcomes, for sample size calculations. The results will inform clinicians, public, service providers, commissioners and policy makers to drive further improvement in health services which will bring direct benefit to the patients.

    U.K ambulance services assess patients with suspected stroke using the Face Arm Speech Test (FAST). The Recognition Of Stroke In the Emergency Room (ROSIER) tool has been shown superior to the FAST in identifying strokes in emergency departments but has not previously been tested in the ambulance setting. We investigated whether ROSIER use by ambulance clinicians can improve stroke recognition. Ambulance clinicians used the ROSIER in place of the FAST to assess patients with suspected stroke. As the ROSIER includes all FAST elements, we calculated a FAST score from the ROSIER to enable comparisons between the two tools. Ambulance clinicians' provisional stroke diagnoses using the ROSIER and calculated FAST were compared with stroke consultants' diagnosis. We used stepwise logistic regression to compare the contribution of individual ROSIER and FAST items and patient demographics to the prediction of consultants' diagnoses. Sixty-four percent of strokes and 78% of nonstrokes identified by ambulance clinicians using the ROSIER were subsequently confirmed by a stroke consultant. There was no difference in the proportion of strokes correctly detected by the ROSIER or FAST with both displaying excellent levels of sensitivity. The ROSIER detected marginally more nonstroke cases than the FAST, but both demonstrated poor specificity. Facial weakness, arm weakness, seizure activity, age, and sex predicted consultants' diagnosis of stroke. The ROSIER was not better than the FAST for prehospital recognition of stroke. A revised version of the FAST incorporating assessment of seizure activity may improve stroke identification and decision making by ambulance clinicians.

    Background A high degree of manual dexterity is a central feature of the human upper limb. A rich interplay of sensory and motor components in the hand and fingers allows for independent control of fingers in terms of timing, kinematics and force. Stroke often leads to impaired hand function and decreased manual dexterity, limiting activities of daily living and impacting quality of life. Clinically, there is a lack of quantitative multi-dimensional measures of manual dexterity. We therefore ...

The purpose of this study was to assess whether the differences in socioeconomic status and living conditions between men and women may explain the part of the sex differences in incidence and outcomes of stroke. Methods: All stroke participants aged ≥60 years admitted in Vaseie Hospital in Sabzevar, Iran, from March 21, 2013, until March 20, 2014, were included in this study. Computerized tomography and magnetic resonance imaging were used to confirm stroke. A series of χ2 tests were performed and Statistical Program for Social Sciences, Version 21.0, was used to investigate the potential differences between older men and women in stroke incidence and outcomes. Results: A total of 159 incident stroke cases were documented during 1 year. The annual rate of stroke was statistically significantly higher in elderly women than in elderly men (401 vs 357 per 100,000; P<0.001. Female elderly participants had significantly lower socioeconomic status, poorer living conditions, and higher lifetime history of depression, hypertension, and diabetes mellitus than their male counterparts.

    Full Text Available Abstract Background The present study was conducted to examine the reliability and validity of the ‘Korean Standard Pattern Identification for Stroke (K-SPI-Stroke’, which was developed and evaluated within the context of traditional Korean medicine (TKM. Methods Between September 2006 and December 2010, 2,905 patients from 11 Korean medical hospitals were asked to complete the K-SPI-Stroke questionnaire as a part of project ' Fundamental study for the standardization and objectification of pattern identification in traditional Korean medicine for stroke (SOPI-Stroke. Each patient was independently diagnosed by two TKM physicians from the same site according to one of four patterns, as suggested by the Korea Institute of Oriental Medicine: 1 a Qi deficiency pattern, 2 a Dampness-phlegm pattern, 3 a Yin deficiency pattern, or 4 a Fire-heat pattern. We estimated the internal consistency using Cronbach’s α coefficient, the discriminant validity using the means score of patterns, and the predictive validity using the classification accuracy of the K-SPI-Stroke questionnaire. Results The K-SPI-Stroke questionnaire had satisfactory internal consistency (α = 0.700 and validity, with significant differences in the mean of scores among the four patterns. The overall classification accuracy of this questionnaire was 65.2 %. Conclusion These results suggest that the K-SPI-Stroke questionnaire is a reliable and valid instrument for estimating the severity of the four patterns.

    Full Text Available Methods currently used in brain vascular disorder diagnostics are neither fast enough nor clear-out; thus, there exists a necessity of finding new types of testing which could enlarge and complete the actual panel of diagnostics or be an alternative to current methods. The discovery of sensitive and specific biomarkers of ischemic brain stroke will improve the effects of treatment and will help to assess the progress or complications of the disease. The relevant diagnosis of ischemic stroke (IS within the first 4.5 hours after the initial symptoms allows for the initiation of treatment with recombinant tissue plasminogen activators which limits the magnitude of negative changes in the brain and which enhance the final effectiveness of therapy. The potential biomarkers which are under investigation are substances involved in the processes of coagulation and fibrinolysis, and are of molecules released from damaged vascular endothelial cells and from nerves and cardiac tissue. The analyzed substances are typical of oxidative stress, apoptosis, excitotoxicity and damage of the blood brain barrier.

    Full Text Available Background: Patients who wake up having experienced a stroke while asleep represent around 20% of acute stroke admissions. According to international guidelines for the management of acute stroke, patients presenting with wake-up stroke are not currently eligible to receive revascularization treatments. In this study, we aimed to assess the opinions of stroke experts about the management of patients with wake-up stroke by using an international multicenter electronic survey. Method: This study consisted of 8 questions on wake-up stroke treatment. Results: Two hundred invitations to participate in the survey were sent by e-mail. Fifty-nine participants started the survey, 4 dropped out before completing it, and 55 completed the full questionnaire. We had 55 participants from 22 countries. Conclusions: In this study, most stroke experts recommended a recanalization treatment for wake-up stroke. However, there was considerable disagreement among experts regarding the best brain imaging method and the best recanalization treatment. The results of ongoing randomized trials on wake-up stroke are urgently needed.

    The adverse health effects of air pollution have long been recognised; however, there is less awareness that the majority of the morbidity and mortality caused by air pollution is due to its effects on the cardiovascular system. Evidence from epidemiological studies have demonstrated a strong association between air pollution and cardiovascular diseases including stroke. Although the relative risk is small at an individual level, the ubiquitous nature of exposure to air pollution means that the absolute risk at a population level is on a par with “traditional” risk factors for cardiovascular disease. Of particular concern are findings that the strength of this association is stronger in low and middle income countries where air pollution is projected to rise as a result of rapid industrialisation. The underlying biological mechanisms through which air pollutants exert their effect on the vasculature are still an area of intense discussion. A greater understanding of the effect size and mechanisms is necessary to develop effective strategies at individual and policy levels to mitigate the adverse cardiovascular effects of air pollution.

    A cost of illness study was undertaken on behalf of the French Ministry of Health to estimate the annual cost of stroke in France with the goal of better understanding the current economic burden so that improved strategies for care may be developed. Using primary data from exhaustive national databases and both top-down and bottom-up approaches, the stroke-related costs for healthcare, nursing care and lost productivity were estimated. The total healthcare cost of stroke patients in France in 2007 was €5.3 billion, 92% of which was borne by statutory health insurance. The average cost of incident cases was €16 686 per patient in the first year, while the annual cost of prevalent cases was a little less than half that amount (€8099). Nursing care costs were estimated at €2.4 billion. Lost productivity reached €255.9 million and that income loss for stroke patients was partially compensated by €63.3 million in social benefit payments. With healthcare costs representing 3% of total health expenditure in France, stroke constitutes an ongoing burden for the health system and overall economy. Nursing care added nearly half again the amount spent on healthcare, while productivity losses were more limited because nearly 80% of acute incident strokes were in patients over age 65. The high cost of illness underscores the need for improved prevention and interventions to limit the disabling effects of stroke. © 2013 The Author(s) European Journal of Neurology © 2013 EFNS.

    Full Text Available Abstract Background Delayed arrival at hospital is one of the major obstacles in enhancing the rate of thrombolysis therapy in patients with acute ischemic stroke. Our study aimed to investigate factors associated with prehospital delay after acute ischemic stroke in Korea. Methods A prospective, multicenter study was conducted at 14 tertiary hospitals in Korea from March 2009 to July 2009. We interviewed 500 consecutive patients with acute ischemic stroke who arrived within 48 hours. Univariate and multivariate analyses were performed to evaluate factors influencing prehospital delay. Results Among the 500 patients (median 67 years, 62% men, the median time interval from symptom onset to arrival was 474 minutes (interquartile range, 170-1313. Early arrival within 3 hours of symptom onset was significantly associated with the following factors: high National Institutes of Health Stroke Scale (NIHSS score, previous stroke, atrial fibrillation, use of ambulance, knowledge about thrombolysis and awareness of the patient/bystander that the initial symptom was a stroke. Multivariable logistic regression analysis indicated that awareness of the patient/bystander that the initial symptom was a stroke (OR 4.438, 95% CI 2.669-7.381, knowledge about thrombolysis (OR 2.002, 95% CI 1.104-3.633 and use of ambulance (OR 1.961, 95% CI 1.176-3.270 were significantly associated with early arrival. Conclusions In Korea, stroke awareness not only on the part of patients, but also of bystanders, had a great impact on early arrival at hospital. To increase the rate of thrombolysis therapy and the incidence of favorable outcomes, extensive general public education including how to recognize stroke symptoms would be important.

    several studies have assessed delirium post-stroke but conflicting results have been obtained. Also, the natural history and outcome of delirium post-stroke need to be fully elucidated. eligible stroke patients were assessed for delirium on admission and for four consecutive weeks using the Confusion Assessment Method (CAM). Risk factors for delirium were recorded. Our outcome measures were length of stay, inpatient mortality and discharge destination. of 110 eligible patients, 82 were recruited over 7 months. Delirium was detected in 23 patients (28%); 21 of these were delirious on their first assessment. Sixty-nine per cent of patients who had four weekly assessments were delirious at 4 weeks. Multivariate logistic regression analysis was performed, and two models were identified. With unsafe swallow in the analysis, delirium was associated with an unsafe swallow on admission (OR 28.4, Pstroke (OR 110.8, P = 0.01). With unsafe swallow removed from the analysis, delirium was associated with an admission C-reactive protein (CRP) > 5 mg/l (OR 10.2, P = 0.009), Barthel score stroke (OR 85.2, P = 0.01). Delirious patients had a higher mortality (30.4% vs. 1.7%, Pvs. 28.9 days, Pvs. 5.2%, OR 14, Pstroke. Most cases develop at stroke onset and remain delirious for an appreciable period. Delirium onset is associated with stroke severity (low admission Barthel), unsafe swallow on admission, poor vision pre-stroke and a raised admission CRP. Delirium is a marker of poor prognosis.

    Stroke can occur during any human activity. Although cardiac arrests or drowning accidents while bathing have been studied extensively, there are few studies focusing on stroke occurring while bathing. The objectives of this study were to evaluate the clinical characteristics of stroke occurring while bathing and the association between stroke and drowning accidents. Clinical data prospectively acquired between January 2011 and December 2015 on 1939 patients with stroke (1224 cerebral infarctions [CIs], 505 intracerebral hemorrhages [ICHs], and 210 subarachnoid hemorrhages [SAHs]) were reviewed to identify patients who sustained a stroke while bathing. The ratio of bathing-related strokes to strokes occurring during other activities was evaluated. Moreover, the demographics of these 2 groups were compared in each stroke type. Among the 1939 patients, 78 (CI, 32; ICH, 28; and SAH, 18) sustained a stroke while bathing. The ratio of bathing to other activities in the SAH group was the highest (8.6%), followed by the ICH group (5.5%), whereas that in the CI group was the lowest (2.6%). Regardless of stroke type, only a minority of patients were found to have collapsed inside the bathtub. The higher ratio of bathing in hemorrhagic strokes may indicate that there is a small risk of hemorrhagic stroke while bathing in vulnerable subjects. This retrospective study did not establish a causal relationship between bathing and stroke nor identify risk factors, which means that future prospective studies are warranted. The finding that the great majority of bathing-related stroke patients were found to have collapsed outside the bathtub suggests that the involvement of stroke in drowning accidents in the bathtub may be small.

    Full Text Available OBJECTIVE: To investigate occurrences of swallowing disorders after ischemic stroke. METHOD: This was a retrospective study on 596 medical files. The inclusion criterion was that the patients needed to have been hospitalized with a diagnosis of ischemic stroke; the exclusion criteria were the presence of associated cardiac problems and hospital stay already more than 14 days. RESULTS: 50.5% were men and 49.5% women; mean age 65.3 years (SD=±11.7 (p<0.001. Among the risk factors, 79.4% had hypertension, 36.7% had diabetes (p<0.001 and 42.7% were smokers. 13.3% of the patients died. Swallowing disorders occurred in 19.6%, among whom 91.5% had mild difficulty and 8.5% had severe difficulty. 87.1% had spontaneous recovery after a mean of 2.4 months. A lesion in the brainstem region occurred in 6.8% (p<0.001. CONCLUSION: Swallowing disorders occurred in almost 20% of the population and most of the difficulty in swallowing found was mild. The predictors for swallowing disorders were older age, diabetes mellitus and lesions in the brainstem region.

    Full Text Available Freehand sketching in a real-time 3D styling system presents a different way to create a 3D model from the traditional CAD system. Strokes are the most common and useful objects in the expression of a stylist’s intention by using the gesture commands and in the construction of geometries. Not only are they sketched freely as drawing on a paper with a pen, but also they can be converted automatically into spline curves and then can be used to form a surface. Therefore, it is necessary to investigate the features of stroke, the extraction and identification of these features, and the applications. Here, the features from a single vector pressure stroke have been discussed in detail according to their applications in an automotive freehand styling system in the early stage of conceptual design. The features have been divided into three parts: the input features, the calculable feature, and the added features. Over a hundred features have been defined and classified with the geometry or performance attributes. The features proposed have been applied in the identification of gesture commands, the expression of art vector stroke by pseudoantialiasing method, and a novel method to generate a spatial curve directly by the pressure of stroke in AutoSketch system.

    To explore the main effects of weather factors on heat stroke. Data from case report on heat stroke was collected in Ningbo city during 2011 to 2014. Temperature threshold, lag effects and interaction of weather factors on heat stroke had been analyzed, using the piecewise regression model, distributed lag non-linear model, response surface model and other methods. RESULTS showed that temperature and humidity were more correlated with heat stroke than other weather-related factors. Through different models, daily average temperature always presented a better role in predicting the heat stroke, rather than maximum or minimum temperature. Positive association between daily average temperature and heat stroke was obvious, especially at lag 0-1 days, with its threshold as 29.1 (95% CI: 28.7-29.5) ℃ . The cumulative RR of heat stroke at 90(th) percentile of daily average temperature versus 10(th) percentile was 14.05 (95% CI: 7.23-27.31) in lag 0-1 days. The effects of daily relative humidity on heat stroke appeared nonlinear, with low humidity showing a negative effect on heat stroke and could lag for 1-4 days. However, the effect of high humidity was not significant, with the cumulative RR of low humidity and high humidity as 2.35 (95%CI: 1.27-4.33) and 0.86 (95%CI: 0.40-1.85) in lag of 0-4 days, respectively. We also noticed that there was an interactive effect of both temperature and humidity on heat stroke. Under high temperature and low humidity, the risk of heat stroke showed the highest. Temperature and humidity showed obvious relationship with heat stroke in Ningbo city, with the threshold temperature as 29.1 ℃. Under high temperature and low humidity, the risk of heat stroke became the highest.

    Time delay from stroke onset to arrival in hospital is an important obstacle to widespread reperfusion therapy. To increase knowledge about stroke, and potentially decrease this delay, a 27-month national public information campaign was carried out in Sweden. To assess the effects of a national stroke campaign in Sweden. The variables used to measure campaign effects were knowledge of the AKUT test [a Swedish equivalent of the FAST (Face-Arm-Speech-Time)] test and intent to call 112 (emergency telephone number) . Telephone interviews were carried out with 1500 randomly selected people in Sweden at eight points in time: before, three times during, immediately after, and nine, 13 and 21 months after the campaign. Before the campaign, 4% could recall the meaning of some or all keywords in the AKUT test, compared with 23% during and directly after the campaign, and 14% 21 months later. Corresponding figures were 15%, 51%, and 50% for those remembering the term AKUT and 65%, 76%, and 73% for intent to call 112 when observing or experiencing stroke symptoms. During the course of the campaign, improvement of stroke knowledge was similar among men and women, but the absolute level of knowledge for both items was higher for women at all time points. The nationwide campaign substantially increased knowledge about the AKUT test and intention to call 112 when experiencing or observing stroke symptoms, but knowledge declined post-intervention. Repeated public information therefore appears essential to sustain knowledge gains. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    To investigate the effects of the kinesio tape application to the tibialis anterior on rehabilitation outcomes of the stroke patients. Twenty patients with stroke were allocated into two groups: the first group of ten patients was assigned to receive kinesio tape in addition to the conventional rehabilitation program while a second group of 10 patients was assigned to receive a conventional rehabilitation program only. The clinical variables and health-related quality of life (HRQoL) were evaluated at baseline and at the end of the forth week. The present study showed that kinesio tape application to the tibialis anterior has significant effects on motor recovery of the lower extremity, spasticity, ambulation capacity, HRQoL and gait compared to the control group and baseline. The results of this study suggest that kinesio tape can be used as an ankle training method. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Lateral medullary stroke is typically associated with increased likelihood of occurrence of dysphagia and exhibits the most severe and persistent form. Worldwide little research exists on dysphagia in brainstem stroke. An estimated 15% of all patients admitted to stroke rehabilitation units experience a brainstem stroke out of which about 47% suffer from dysphagia. In India, a study showed that 22.3% of posterior circulation stroke patients develop dysphagia. Dearth of literature on dysphagia and its outcome in brainstem stroke particularly lateral medullary stroke motivated the author to present an actual case study of a patient who had dysphagia following a lateral medullary infarct. This paper documents the severity and management approach of dysphagia in brainstem stroke, with traditional dysphagia therapy and VitalStim therapy. Despite being diagnosed with a severe form of dysphagia followed by late treatment intervention, the patient had complete recovery of the swallowing function.

    Full Text Available OBJECTIVE: To investigate the prevalence of obstructive sleep apnea in patients with ischemic stroke and to evaluate the effectiveness of nasal continuous positive airway pressure treatment. METHODS: Overnight polysomnography was performed by a computerized system in 19 subjects with ischemic stroke. Patients with an apnea-hypopnea index > 5 were considered to have obstructive sleep apnea. The appropriate level of continuous positive airway pressure for each patient was determined during an all-night continuous positive airway pressure determination study. Attended continuous positive airway pressure titration was performed with a continuous positive airway pressure auto-titrating device. RESULTS: Obstructive sleep apnea prevalence among patients with ischemic stroke was 73.7%. The minimum SaO2 was significantly lower, and the percent of total sleep time in the wake stage and stage 1 sleep was significantly longer in patients with obstructive sleep apnea. In two patients with severe obstructive sleep apnea, we observed a decrease in the apnea-hypopnea index, an increase in mean wake time, mean SaO2, and minimum SaO2, and alterations in sleep structures with continuous positive airway pressure treatment. CONCLUSION: As the diagnosis and treatment of obstructive sleep apnea is of particular importance in secondary stroke prevention, we suggest that the clinical assessment of obstructive sleep apnea be part of the evaluation of stroke patients in rehabilitation units, and early treatment should be started.

    Full Text Available The stroke is the third cause of death and the main cause of disability in adults. 30% of ischaemic strokes are cryptogenic. Atrial Fibrillation (AF is a common disease, mainly among older patients (pts (9% of people over 80. AF is an indipendent risk factor for stroke, and 15% of ischaemic strokes are due to AF (25% in older people. The cardioembolic risk is determinated by duration of AF and comorbilities: high risk pts are identified by risk score scales, in order to define who needs anticoagulation. Identification of pts with AF, symptomatic or not, is mandatory to prevent thromboembolism. Thrombo - embolic complications of asymptomatic AF (half of episodes are asymptomatic are similar to symptomatic. Accuracy of methods for AF detection is higher if the monitored period is long, in particular for detection of asymptomatic AF. A careful identification of asymptomatic AF is mandatory to indicate the anticoagulation therapy in people with thromboembolic risk factor: in particular, pts with a previous stroke need to detect carefully potential arrhythmias in order to avoid relapses.

  20. Radiology in cases of cerebral stroke

    Forsting, M.; Reith, W.; Kummer, R. von; Sartor, K.

    1993-01-01

    Today radiologic methods play an important role in the diagnosis of cerebral stroke. The aim of the radiologist, however, should not only be to classify the stroke into the four main categories (ischemic stroke, intracerebral bleeding, subarachnoid hemorrhage, sinovenous thrombis), but also to interprete the findings with regard to the etiology of the disease. The pattern of lesions gives information about the etiology of ischemic stroke; the correct interpretation of these lesion patterns allows one to optimize therapeutic decisions. This paper additionally focusses on the differential diagnosis of intracerebral hemorrhage and the CT and MR signs of sinovenous thrombosis. New developed concepts in the field of stroke therapy and prophylaxis call for authority and continuous education of the radiolgist on this topic. Pure descriptions of radiologic findings without an understanding of the pathogenesis of the disease will be ignored by the clinician. On the other hand, the radiologist can turn the therapeutic decisions in the right direction by combining morphological descriptions with pathogenetic orientated interpretations. In this way, the radiolgist can contribute to the reduction of costs in the public health system. (orig.) [de

    Full Text Available Objective. To explore exercise preferences in stroke survivors and controls. Methods. A novel scale—the Exercise Preference Questionnaire—was developed for this study. This questionnaire, together with established assessments of physical activities, mood, and quality of life, was completed in a single assessment session. Results. Twenty-three adult stroke survivors (mean age 63, 65% male and 41 healthy controls (mean age 61, 66% male participated. The groups differed on 4 of the 5 a priori exercise preference factors: relative to controls, stroke survivors preferred exercise to be more structured, in a group, at a gym or fitness centre, and for exercises to be demonstrated. Factor analysis yielded 6 data-driven factors, and these factors also differentiated stroke and control groups. There was evidence that group differences were diminished when activity levels and psychological wellbeing were accounted for. Individual variability in exercise preferences and reported barriers to exercise are outlined. Conclusion. Stroke survivors have different exercise preferences, and a better understanding of these preferences can be used to inform rehabilitation programs and increase adherence.

    This preliminary study sought to analyze the effects of a training program based on the Proprioceptive Neuromuscular Facilitation (PNF) method on motor recovery of individuals with chronic post-stroke hemiparesis. Eleven individuals with chronic hemiparesis (mean lesion time of 19.64 months) after unilateral and non-recurrent stroke underwent training based on PNF method for twelve sessions, being evaluated for motor function - using the Stroke Rehabilitation Assessment of Movement (STREAM) instrument; functionality, by the Functional Independence Measure (FIM); and gait kinematic (using the Qualisys Motion Capture System), at baseline and post-training. Significant changes in FIM (from median 67 to median 68; P = .043) and STREAM scores (from median 47 to median 55; P = .003) were observed. Data showed significant changes in motor function and functionality after training, suggesting that this program can be useful for rehabilitation of chronic stroke survivors.

    We present the first attempt to extract vertical stroke V{sub cb} vertical stroke from the Λ{sub b} → Λ{sub c}{sup +}l anti ν{sub l} decay without relying on vertical stroke V{sub ub} vertical stroke inputs from the B meson decays. Meanwhile, the hadronic Λ{sub b} → Λ{sub c}M{sub (c)} decays with M = (π{sup -},K{sup -}) and M{sub c} =(D{sup -},D{sup -}{sub s}) measured with high precisions are involved in the extraction. Explicitly, we find that vertical stroke V{sub cb} vertical stroke =(44.6 ± 3.2) x 10{sup -3}, agreeing with the value of (42.11 ± 0.74) x 10{sup -3} from the inclusive B → X{sub c}l anti ν{sub l} decays. Furthermore, based on the most recent ratio of vertical stroke V{sub ub} vertical stroke / vertical stroke V{sub cb} vertical stroke from the exclusive modes, we obtain vertical stroke V{sub ub} vertical stroke = (4.3 ± 0.4) x 10{sup -3}, which is close to the value of (4.49 ± 0.24) x 10{sup -3} from the inclusive B → X{sub u}l anti ν{sub l} decays. We conclude that our determinations of vertical stroke V{sub cb} vertical stroke and vertical stroke V{sub ub} vertical stroke favor the corresponding inclusive extractions in the B decays. (orig.)

    Huddleston, Lisa L.; Roeder, William; Merceret, Francis J.

    2010-01-01

    A technique has been developed to calculate the probability that any nearby lightning stroke is within any radius of any point of interest. In practice, this provides the probability that a nearby lightning stroke was within a key distance of a facility, rather than the error ellipses centered on the stroke. This process takes the current bivariate Gaussian distribution of probability density provided by the current lightning location error ellipse for the most likely location of a lightning stroke and integrates it to get the probability that the stroke is inside any specified radius. This new facility-centric technique will be much more useful to the space launch customers and may supersede the lightning error ellipse approach discussed in [5], [6].

    Full Text Available Little is known about stroke patients’ awareness about the warning signs of stroke and its therapeutic time window in Brazil. Method We interviewed consecutive patients with acute stroke admitted to a terciary public hospital in Brazil. Data collected included demographics, mode of arrival, National Institutes of Health Stroke Scale (NIHSS scores and knowledge of stroke warning signs and therapeutic time window. Early arrival was defined as within 4.5 hours of symptoms onset. Results Although 66.2% of patients knew the warning signs of stroke, only 7.8% reported to know that stroke had a limited therapeutic time window. Stroke severity measured by the NIHSS was independently associated with early arrival, but not knowledge of stroke signs and symptoms. Conclusion Knowledge about stroke symptoms was not a predictor of early arrival.

    Background ABO blood type is an inherited trait associated with coagulation factor levels and vascular outcomes. Objectives To assess the association of blood type with stroke and whether blood type contributes to racial disparities in stroke in the United States. Patients and Methods The REasons for Geographic and Racial Differences in Stroke (REGARDS) Study recruited 30,239 participants between 2003-07. Using a case-cohort design, blood type was genotyped in 646 participants with stroke and a 1,104 participant cohort random sample. Cox models adjusting for Framingham stroke risk factors assessed the association of blood type with stroke. Results Over 5.8 years of follow-up, blood types A or B versus type O were not associated with stroke. Blood type AB versus O was associated with an increased risk of stroke (adjusted HR 1.83; 95% CI 1.01, 3.30). The association of blood type AB versus O was greater in those without diabetes (adjusted HR 3.33; 95% CI 1.61, 6.88) than those with diabetes (adjusted HR 0.49; 95% CI 0.17, 1.44) (p-interaction = 0.02). Factor VIII levels accounted for 60% (95% CI 11%, 98%) of the association of AB blood type and stroke risk. Conclusion Blood type AB is associated with an increased risk of stroke that is not attenuated by conventional stroke risk factors and factor VIII levels were associated with 60% of the association. While blood type AB is rare in the U.S. population, it is a significant stroke risk factor and may play an important role in stroke risk in these individuals. PMID:24444093

    Konings Maurits K

    2012-08-01

    Full Text Available Abstract Background In this paper a new non-invasive, operator-free, continuous ventricular stroke volume monitoring device (Hemodynamic Cardiac Profiler, HCP is presented, that measures the average stroke volume (SV for each period of 20 seconds, as well as ventricular volume-time curves for each cardiac cycle, using a new electric method (Ventricular Field Recognition with six independent electrode pairs distributed over the frontal thoracic skin. In contrast to existing non-invasive electric methods, our method does not use the algorithms of impedance or bioreactance cardiography. Instead, our method is based on specific 2D spatial patterns on the thoracic skin, representing the distribution, over the thorax, of changes in the applied current field caused by cardiac volume changes during the cardiac cycle. Since total heart volume variation during the cardiac cycle is a poor indicator for ventricular stroke volume, our HCP separates atrial filling effects from ventricular filling effects, and retrieves the volume changes of only the ventricles. Methods ex-vivo experiments on a post-mortem human heart have been performed to measure the effects of increasing the blood volume inside the ventricles in isolation, leaving the atrial volume invariant (which can not be done in-vivo. These effects have been measured as a specific 2D pattern of voltage changes on the thoracic skin. Furthermore, a working prototype of the HCP has been developed that uses these ex-vivo results in an algorithm to decompose voltage changes, that were measured in-vivo by the HCP on the thoracic skin of a human volunteer, into an atrial component and a ventricular component, in almost real-time (with a delay of maximally 39 seconds. The HCP prototype has been tested in-vivo on 7 human volunteers, using G-suit inflation and deflation to provoke stroke volume changes, and LVot Doppler as a reference technique. Results The ex-vivo measurements showed that ventricular filling

    2002-07-01

    There is increasing evidence that environmental and neuropharmacologic treatments enhance stroke recovery. Functional magnetic resonance imaging and transcranial magnetic stimulation have significantly broadened our understanding of the neuroanatomic relationships involved in recovery from brain injury due to stroke. These tools have also demonstrated the role for pharmacologic enhancement of cortical plasticity coupled with behavioral interventions. Robot-assisted therapy and partial body weight-supported treadmill gait training have demonstrated the role for technologic intervention in the modern neuro-rehabilitation setting. Current research using hemi-field ocular prisms and patching techniques suggest a role in the rehabilitation of hemianopsia and visual neglect. Finally, many advances have been made in the understanding of common stroke complications, such as depression, dysphagia, venous thromboembolic disease, incontinence, and spasticity.

    Artificial intelligence (AI), a computer system aiming to mimic human intelligence, is gaining increasing interest and is being incorporated into many fields, including medicine. Stroke medicine is one such area of application of AI, for improving the accuracy of diagnosis and the quality of patient care. For stroke management, adequate analysis of stroke imaging is crucial. Recently, AI techniques have been applied to decipher the data from stroke imaging and have demonstrated some promising results. In the very near future, such AI techniques may play a pivotal role in determining the therapeutic methods and predicting the prognosis for stroke patients in an individualized manner. In this review, we offer a glimpse at the use of AI in stroke imaging, specifically focusing on its technical principles, clinical application, and future perspectives.

    2012-09-12

    Piracetam has neuroprotective and antithrombotic effects that may help to reduce death and disability in people with acute stroke. This is an update of a Cochrane Review first published in 1999, and previously updated in 2006 and 2009. To assess the effects of piracetam in acute, presumed ischaemic stroke. We searched the Cochrane Stroke Group Trials Register (last searched 15 May 2011), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 2), MEDLINE (1966 to May 2011), EMBASE (1980 to May 2011), and ISI Science Citation Index (1981 to May 2011). We also contacted the manufacturer of piracetam to identify further published and unpublished studies. Randomised trials comparing piracetam with control, with at least mortality reported and entry to the trial within three days of stroke onset. Two review authors extracted data and assessed trial quality and this was checked by the other two review authors. We contacted study authors for missing information. We included three trials involving 1002 patients, with one trial contributing 93% of the data. Participants' ages ranged from 40 to 85 years, and both sexes were equally represented. Piracetam was associated with a statistically non-significant increase in death at one month (approximately 31% increase, 95% confidence interval 81% increase to 5% reduction). This trend was no longer apparent in the large trial after correction for imbalance in stroke severity. Limited data showed no difference between the treatment and control groups for functional outcome, dependence or proportion of patients dead or dependent. Adverse effects were not reported. There is some suggestion (but no statistically significant result) of an unfavourable effect of piracetam on early death, but this may have been caused by baseline differences in stroke severity in the trials. There is not enough evidence to assess the effect of piracetam on dependence.

  11. Hypothermia for treatment of stroke

    Directory of Open Access Journals (Sweden)

    Jong Youl Kim

    2015-01-01

    Full Text Available Stroke is a major cause of neurological disability and death in industrialized nations. Therapeutic hypothermia has been shown to protect the brain from ischemia, stroke, and other acute neurological insults at the laboratory level. It has been shown to improve neurological outcome in certain clinical settings including anoxic brain injury due to cardiac arrest and hypoxic-ischemic neonatal encephalopathy. Hypothermia seems to affect multiple aspects of brain physiology and it is likely that multiple mechanisms underlie its protective effect. Understanding the events that occur in the ischemic brain during hypothermia might help lead to an understanding of how to protect the brain against acute injuries.

  12. Maintaining oral health after stroke.

    Dickinson, Hazel

    Oral care is essential to maintain oral health and prevent complications such as tooth loss, gingivitis and periodontitis. Poor oral hygiene in dependent, hospitalised patients could lead to serious complications such as chest infection, pneumonia, poor nutritional intake and increased length of hospital stay. Patients who have had a stroke may have physical and cognitive problems that make them dependent on others for their personal care, including oral care. It is essential that nurses and carers understand why maintaining oral hygiene is important following stroke and the consequences of poor oral care.

    There is increasing evidence that inflammatory responses play an important role in the pathogenesis of atherosclerosis and cerebral infarct. The aim of this study was to determine the amount of immunocomplexes (i.c.) in patients with stroke in the early period of the disease. Studies were performed on 35 subjects. The concentration of immunocomplexes was determined with the precipitation method (3.5% polyethylenoglikol was used). Increased concentration of i.c. was found in patients with cerebral infarct (after 12 hours and 7 days). It suggests, that i.c. could be one of the markers for systemic inflammation and be important in the patogenesis of atherosclerosis and stroke.

  19. Management Of Post Stroke Seizures

    Directory of Open Access Journals (Sweden)

    Kavian Ghandehari

    2017-02-01

    Full Text Available The incidence of seizures in relation to stroke is 8.9%, with a frequency of 10.6 and 8.6% in haemorrhagic and ischaemic stroke, respectively. In subarachnoid haemorrhage the incidence is 8.5%. Due to the fact that infarcts are significantly more frequent than haemorrhages, seizures are mainly related to occlusive vascular disease of the brain. The general view is to consider stroke-related seizures as harmless complications in the course of a prolonged vascular disease involving the heart and brain. Seizures can be classified as those of early and those of late onset in a paradigm comparable to post-traumatic epilepsy, with an arbitrary dividing point of two weeks after the event. Most early-onset seizures occur during the first day after the stroke. Late-onset seizures occur three times more often than early-onset ones. A first late-onset epileptic event is most likely to take place between six months and two years after the stroke. However, up to 28% of patients develop their first seizure several years later. Simple partial seizures, with or without secondary generalisation, account for about 50% of total seizures, while complex partial spells, with or without secondary generalisation, and primary generalised tonic–clonic insults account for approximately 25% each. Status epilepticus occurs in 12% of stroke patients, but the recurrence rate after an initial status epilepticus is not higher than after a single seizure. Inhibitory seizures, mimicking transient ischaemic attacks, are observed in 7.1% of cases. The only clinical predictor of late-onset seizures is the initial presentation of partial anterior circulation syndrome due to a territorial infarct. Patients with total anterior circulation syndrome have less chance of developing epileptic spells, not only due to their shorter life expectancy but also due to the fact that the large infarcts are sharply demarcated in these patients. The optimal timing and type of antiepileptic drug

    Full Text Available This paper focuses on radiological approach in pediatric stroke including both ischemic stroke (Arterial Ischemic Stroke and Cerebral Sinovenous Thrombosis and hemorrhagic stroke. Etiopathology and main clinical findings are examined as well. Magnetic Resonance Imaging could be considered as the first-choice diagnostic exam, offering a complete diagnostic set of information both in the discrimination between ischemic/hemorrhagic stroke and in the identification of underlying causes. In addition, Magnetic Resonance vascular techniques supply further information about cerebral arterial and venous circulation. Computed Tomography, for its limits and radiation exposure, should be used only when Magnetic Resonance is not available and on unstable patients.

  1. Executive function and coping in stroke survivors.

    Stroke is a leading cause of disability and sequelae may include physical, emotional, and cognitive impairments. The methods employed to cope with distress, both emotional and cognitive, have not been evaluated in individuals post-stroke. However, research in traumatic brain injury (TBI) suggests that executive function is positively correlated with adaptive coping and negatively correlated with maladaptive coping strategies (Krpan et al., 2007). Examination of these constructs post-stroke may assist with enriching our understanding of cognitive and emotional symptomatology and optimize rehabilitation strategies. The present study aimed to assess the association between executive function and coping strategies in a sample of chronic stroke survivors. The researchers hypothesized that executive function would be positively correlated with adaptive coping strategies and negatively correlated with maladaptive coping strategies. Fifteen stroke survivors were administered a battery of cognitive tests assessing executive function and also completed the Ways of Coping Questionnaire (WAYS), a self-report coping measure. Analyses indicated that executive function deficits were related to increased avoidant coping. Contrary to expectations, executive function was not significantly related to active coping. In addition, post hoc analyses revealed that executive function was a significant predictor of avoidant coping after controlling for demographics. Our data, in accordance with prior work in TBI, suggests that executive function and aspects of coping are associated. Rehabilitation strategies that improve executive function may also lead to utilization of adaptive coping strategies. Research has shown that aerobic exercise increases activation in the frontal lobe and improves executive function (Colcombe & Kramer, 2003; Colcombe et al., 2004). Future studies should examine whether aerobic exercise positively affects executive function and coping in stroke survivors.

    2016-01-01

    Objective: To determine the independent effects of aphasia on outcomes during acute stroke admission, controlling for total NIH Stroke Scale (NIHSS) scores and loss of consciousness. Methods: Data from the Tulane Stroke Registry were used from July 2008 to December 2014 for patient demographics, NIHSS scores, length of stay (LOS), complications (sepsis, deep vein thrombosis), and discharge modified Rankin Scale (mRS) score. Aphasia was defined as a score >1 on question 9 on the NIHSS on admission and hemiparesis as >1 on questions 5 or 6. Results: Among 1,847 patients, 866 (46%) had aphasia on admission. Adjusting for NIHSS score and inpatient complications, those with aphasia had a 1.22 day longer LOS than those without aphasia, whereas those with hemiparesis (n = 1,225) did not have any increased LOS compared to those without hemiparesis. Those with aphasia had greater odds of having a complication (odds ratio [OR] 1.44, confidence interval [CI] 1.07–1.93, p = 0.0174) than those without aphasia, which was equivalent to those having hemiparesis (OR 1.47, CI 1.09–1.99, p = 0.0137). Controlling for NIHSS scores, aphasia patients had higher odds of discharge mRS 3–6 (OR 1.42 vs 1.15). Conclusion: Aphasia is independently associated with increased LOS and complications during the acute stroke admission, adding $2.16 billion annually to US acute stroke care. The presence of aphasia was more likely to produce a poor functional outcome than hemiparesis. These data suggest that further research is necessary to determine whether establishing adaptive communication skills can mitigate its consequences in the acute stroke setting. PMID:27765864

    Full Text Available AbstractObjective:The clinical features of cardiac myxoma stroke have not been sufficiently described. Debates remain concerning the options and timing of treatment and the clinical outcomes are unknown. This article aims to highlight the pertinent aspects of this rare condition.Methods:Data source of the present study came from a comprehensive literature collection of cardiac myxoma stroke in PubMed, Google search engine and Highwire Press for the year range 2000-2014.Results:Young adults, female predominance, single cerebral vessel (mostly the middle cerebral artery, multiple territory involvements and solitary left atrial myxoma constituted the outstanding characteristics of this patient setting. The most common affected cerebral vessel (the middle cerebral artery and areas (the basal ganglion, cerebellum and parietal and temporal regions corresponded well to the common manifestations of this patient setting, such as conscious alteration, ataxia, hemiparesis and hemiplegia, aphasia and dysarthria. Initial computed tomography scan carried a higher false negative rate for the diagnosis of cerebral infarction than magnetic resonance imaging did. A delayed surgical resection of cardiac myxoma was associated with an increased risk of potential consequences in particular otherwise arterial embolism. The mortality rate of this patient population was 15.3%.Conclusion:Cardiac myxoma stroke is rare. Often does it affect young females. For an improved diagnostic accuracy, magnetic resonance imaging of the brain and echocardiography are imperative for young stroke patients in identifying the cerebral infarct and determining the stroke of a cardiac origin. Immediate thrombolytic therapy may completely resolve the cerebral stroke and improve the neurologic function of the patients. An early surgical resection of cardiac myxoma is recommended in patients with not large territory cerebral infarct.

    Objectives: This article provides recommendations on the use of antithrombotic therapy in patients with stroke or transient ischemic attack (TIA). Methods: We generated treatment recommendations (Grade 1) and suggestions (Grade 2) based on high (A), moderate (B), and low (C) quality evidence. Results: In patients with acute ischemic stroke, we recommend IV recombinant tissue plasminogen activator (r-tPA) if treatment can be initiated within 3 h (Grade 1A) or 4.5 h (Grade 2C) of symptom onset; we suggest intraarterial r-tPA in patients ineligible for IV tPA if treatment can be initiated within 6 h (Grade 2C); we suggest against the use of mechanical thrombectomy (Grade 2C) although carefully selected patients may choose this intervention; and we recommend early aspirin therapy at a dose of 160 to 325 mg (Grade 1A). In patients with acute stroke and restricted mobility, we suggest the use of prophylactic-dose heparin or intermittent pneumatic compression devices (Grade 2B) and suggest against the use of elastic compression stockings (Grade 2B). In patients with a history of noncardioembolic ischemic stroke or TIA, we recommend long-term treatment with aspirin (75-100 mg once daily), clopidogrel (75 mg once daily), aspirin/extended release dipyridamole (25 mg/200 mg bid), or cilostazol (100 mg bid) over no antiplatelet therapy (Grade 1A), oral anticoagulants (Grade 1B), the combination of clopidogrel plus aspirin (Grade 1B), or triflusal (Grade 2B). Of the recommended antiplatelet regimens, we suggest clopidogrel or aspirin/extended-release dipyridamole over aspirin (Grade 2B) or cilostazol (Grade 2C). In patients with a history of stroke or TIA and atrial fibrillation we recommend oral anticoagulation over no antithrombotic therapy, aspirin, and combination therapy with aspirin and clopidogrel (Grade 1B). Conclusions: These recommendations can help clinicians make evidence-based treatment decisions with their patients who have had strokes. PMID:22315273

    OBJECTIVE Despite established risk factors, abusive head trauma (AHT) continues to plague our communities. Cerebrovascular accident (CVA), depicted as areas of hypodensity on CT scans or diffusion restriction on MR images, is a well-known consequence of AHT, but its etiology remains elusive. The authors hypothesize that a CVA, in isolation or in conjunction with other intracranial injuries, compounds the severity of a child's injury, which in turn leads to greater health care utilization, including surgical services, and an increased risk of death. METHODS The authors conducted a retrospective observational study to evaluate data obtained in all children with AHT who presented to Le Bonheur Children's Hospital (LBCH) from January 2009 through August 2016. Demographic, hospital course, radiological, cost, and readmission information was collected. Children with one or more CVA were compared with those without a CVA. RESULTS The authors identified 282 children with AHT, of whom 79 (28%) had one or more CVA. Compared with individuals without a CVA, children with a stroke were of similar overall age (6 months), sex (61% male), and race (56% African-American) and had similar insurance status (81% public). Just under half of all children with a stroke (38/79, 48%) were between 1-6 months of age. Thirty-five stroke patients (44%) had a Grade II injury, and 44 (56%) had a Grade III injury. The majority of stroke cases were bilateral (78%), multifocal (85%), associated with an overlying subdural hematoma (86%), and were watershed/hypoperfusion in morphology (73%). Thirty-six children (46%) had a hemispheric stroke. There were a total of 48 neurosurgical procedures performed on 28 stroke patients. Overall median hospital length of stay (11 vs 3 days), total hospital charges ($13.8 vs $6.6 million), and mean charges per patient ($174,700 vs $32,500) were significantly higher in the stroke cohort as a whole, as well as by injury grade (II and III). Twenty children in the

    Stroke volume is probably the best hemodynamic parameter because it reflects therapeutic changes and contains prognostic information in pulmonary hypertension (PH). Stroke volume directly reflects right ventricular function in response to its load, without the correction of compensatory increased heart rate as is the case for cardiac output. For this reason, stroke volume, which can be measured noninvasively, is an important hemodynamic parameter to monitor during treatment. However, the extent of change in stroke volume that constitutes a clinically significant change is unknown. The aim of this study was to determine the minimal important difference (MID) in stroke volume in PH. One hundred eleven patients were evaluated at baseline and after 1 year of follow-up with a 6-min walk test (6MWT) and cardiac MRI. Using the anchor-based method with 6MWT as the anchor, and the distribution-based method, the MID of stroke volume change could be determined. After 1 year of treatment, there was, on average, a significant increase in stroke volume and 6MWT. The change in stroke volume was related to the change in 6MWT. Using the anchor-based method, an MID of 10 mL in stroke volume was calculated. The distribution-based method resulted in an MID of 8 to 12 mL. Both methods showed that a 10-mL change in stroke volume during follow-up should be considered as clinically relevant. This value can be used to interpret changes in stroke volume during clinical follow-up in PH.

    Full Text Available Abstract Background Statins (3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors have neuroprotective effects in experimental stroke models and are commonly prescribed in clinical practice. The aim of this study was to determine if patients taking statins before hospital admission for stroke had an improved clinical outcome. Methods This was an observational study of 436 patients admitted to the National Institutes of Health Suburban Hospital Stroke Program between July 2000 and December 2002. Self-reported risk factors for stroke were obtained on admission. Stroke severity was determined by the admission National Institutes of Health Stroke Scale score. Good outcome was defined as a Rankin score Results There were 436 patients with a final diagnosis of ischemic stroke; statin data were available for 433 of them. A total of 95/433 (22% of patients were taking a statin when they were admitted, rising from 16% in 2000 to 26% in 2002. Fifty-one percent of patients taking statins had a good outcome compared to 38% of patients not taking statins (p = 0.03. After adjustment for confounding factors, statin pretreatment was associated with a 2.9 odds (95% CI: 1.2–6.7 of a good outcome at the time of hospital discharge. Conclusions The proportion of patients taking statins when they are admitted with stroke is rising rapidly. Statin pretreatment was significantly associated with an improved functional outcome at discharge. This finding could support the early initiation of statin therapy after stroke.

    Full Text Available Objective: Stroke guideline compliance of rural Canadian prehospital emergency medical services (EMS care in acute stroke is unknown. In this quality assurance study, we sought to compare rural and urban care by prehospital EMS evaluation/management indicators from patients assessed at an urban Canadian stroke center. Materials and Methods: One hundred adult patients were randomly selected from the stroke registry. Patients were transported through Rural EMS bypass protocols or urban EMS protocols (both bypass and direct to our stroke center between January and December 2013. Patients were excluded if they were first evaluated at any other health center. Prehospital care was assessed using ten indicators for EMS evaluation/management, as recommended by acute stroke guidelines. Results: Compliance with acute stroke EMS evaluation/management indicators were statistically similar for both groups, except administrating a prehospital diagnostic tool (rural 31.8 vs. urban 70.3%; P = 0.002. Unlike urban EMS, rural EMS did not routinely document scene time. Conclusion: Rural EMS responders' compliance to prehospital stroke evaluation/management was similar to urban EMS responders. Growth areas for both groups may be with prehospital stroke diagnostic tool utilization, whereas rural EMS responders may also improve with scene time documentation.

    2017-07-01

    Full Text Available BACKGROUND Stroke is a major cause of long term morbidity and mortality. Several factors are known to increase the liability to stroke. Platelets play a crucial role in the pathogenesis of atherosclerotic complications, contributing to thrombus formation. Platelet size (mean platelet volume, MPV is a marker and possible determinant of platelet function, large platelets being potentially more reactive. Hence an attempt has-been made to study the association if any between mean platelet volume and thrombotic stroke. The aim of this study was to determine whether an association exists between Mean Platelet Volume (MPV and thrombotic stroke. MATERIALS AND METHODS The study is a case control study and data was collected at Government Medical College Hospital, Kottayam, Kerala a tertiary care referral centre. The study was carried out among fifty patients diagnosed with thrombotic stroke and presenting to the hospital within forty eight hours of onset of symptoms. Fifty age group and sex matched controls were also recruited. Mean platelet volume was obtained using a SYSMEX automated analyser. RESULTS This study has shown a statistically significant relation between mean platelet volume and risk of thrombotic stroke but no statistically significant correlation between clinical severity of stroke and mean platelet volume. CONCLUSION This study has shown an elevation of MPV in acute phase of thrombotic stroke. Platelet mass was found to be more or less a constant. This study did not find a statistically significant correlation between clinical severity of stroke and mean platelet volume.

  10. Anticoagulation in acute ischemic stroke: A systematic search

    Directory of Open Access Journals (Sweden)

    Nayara L. Froio

    Full Text Available Summary Introduction: Stroke is one of the most important diseases worldwide. Several clinical scenarios demand full dose of anticoagulants primary to stroke etiology or to the treatment of comorbidity. However, controversy exists over many issues regarding anticoagulation treatment in stroke such as time for initiation, efficacy according to stroke etiology, the ideal dose of anticoagulants, and whether novel anticoagulants should be used. Method: Computerized search for clinical trials and randomized controlled clinical trials was done to the present date at Medline, Scielo, Embase, PsychInfo, and Cochrane Library using MeSH terms and the keywords stroke, ischemic stroke, anticoagulation, anticoagulants, heparin, low-molecular-weight heparin, warfarin, dabigatran, rivaroxaban, apixaban. The PRISMA statement was used to evaluate clinical trials. Results: Fourteen clinical trials were selected based on inclusion criteria. No evidence was found supporting the early use of heparin, heparinoids or low-molecular-weight heparin (LMWH early after stroke. No consistent evidence for the use of warfarin and the newer oral anticoagulants were found. Argatroban was the only anticoagulant with significant positive results early after large-artery ischemic stroke. Conclusion: The ideal time for initiating anticoagulation remains undefined, requiring further investigation. Early anticoagulation for ischemic stroke is not recommended, with few exceptions, such as that of argatroban.

    Anxiety in stroke patients is very frequent. It negatively influences the whole recovery process. The study objective is to study personality traits, age, gender, and type of stroke as predictors of anxiety in stroke patients. Research presents a prospective cross-sectional descriptive study. The sample consisted of 74 hospitalized stroke patients. The data collection methods were the HADS for anxiety measurement and the Mini IPIP for evaluation of five personality factors. Hierarchical multiple regression analysis was used to study the relationship between anxiety and personality variables, gender, age, and type of stroke. We found three statistically significant predictors of anxiety in stroke patients. Neuroticism and low Agreeableness explain 50% of the variability of anxiety. Another statistically significant predictor was age; higher-level anxiety relates to lower age. Other personality traits (Extraversion, Openness to experience, and Conscientiousness), gender, and type of stroke do not appear as significant predictors of post-stroke anxiety. Anxiety in stroke patients is predicted mostly by the personality traits and young age of patients. Knowing these predictors can result in early detection and management of emotional consequences of disease, and thus influence the whole recovery process.

    Chronic upper extremity impairment due to stroke has significant medical, psychosocial, and financial consequences, but few studies have examined the effectiveness of rehabilitation therapy during the chronic stroke period. . To test the safety and efficacy of the MIT-Manus robotic device for chronic upper extremity impairment following stroke. . The VA Cooperative Studies Program initiated a multicenter, randomized, controlled trial in November 2006 (VA ROBOTICS). Participants with upper extremity impairment >/=6 months poststroke were randomized to robot-assisted therapy (RT), intensive comparison therapy (ICT), or usual care (UC). RT and ICT consisted of three 1-hour treatment sessions per week for 12 weeks. The primary outcome was change in the Fugl-Meyer Assessment upper extremity motor function score at 12 weeks relative to baseline. Secondary outcomes included the Wolf Motor Function Test and the Stroke Impact Scale. . A total of 127 participants were randomized: 49 to RT, 50 to ICT, and 28 to UC. The majority of participants were male (96%), with a mean age of 65 years. The primary stroke type was ischemic (85%), and 58% of strokes occurred in the anterior circulation. Twenty percent of the participants reported a stroke in addition to their index stroke. The average time from the index stroke to enrollment was 56 months (range, 6 months to 24 years). The mean Fugl-Meyer score at entry was 18.9. . VA ROBOTICS demonstrates the feasibility of conducting multicenter clinical trials to rigorously test new rehabilitative devices before their introduction to clinical practice. The results are expected in early 2010.

    Acupuncture is one of the most important parts of Traditional Chinese Medicine, has been used for more than 3000 years as prevention and treatment for various diseases in China as well as in adjacent regions, and is widely accepted in western countries in recent years. More and more clinical trials revealed that acupuncture shows positive effect in stroke, not only as a complementary and alternative medicine for poststroke rehabilitation but also as a preventive strategy which could induce cerebral ischemic tolerance, especially when combined with modern electrotherapy. Acupuncture has some unique characteristics, which include acupoint specificity and parameter-dependent effect. It also involves complicated mechanism to exert the beneficial effect on stroke. Series of clinical trials have shown that acupuncture primarily regulates the release of neurochemicals, hemorheology, cerebral microcirculation, metabolism, neuronal activity, and the function of specific brain region. Animal studies showed that the effects of acupuncture therapy on stroke were possibly via inhibition of postischemic inflammatory reaction, stimulation of neurogenesis and angiogenesis, and influence on neural plasticity. Mechanisms for its preconditioning effect include activity enhancement of antioxidant, regulation of the endocannabinoid system, and inhibition of apoptosis. Although being controversial, acupuncture is a promising preventive and treatment strategy for stroke, but further high-quality clinical trials would be needed to provide more confirmative evidence. © 2013 Elsevier Inc.

    After chronic stroke, inability to use pertinent somatosensory or vestibular information have been described. The aim of the study was to determine whether visual dependence occurred early after stroke before rehabilitation. Thirty patients with recent hemiplegia (16 right and 14 left hemispheric stroke) performed the rod and frame test (RFT). Patients were asked to adjust the rod to the vertical position under 3 conditions: basically, with a frame tilted 18 degrees to the right and then with the frame tilted to the left. Bias in each condition (mean, SD) was recorded and compared to adjustments of the rod by 23 controls. Motor control, sensibility, functional level (functional independence measure), age, neglect, and then balance by the postural assessment scale for stroke were assessed. Fifty-six per cent (17/30) of patients but only 26% of controls were influenced by the tilt of the frame on the 2 sides (visual dependence). No correlation was found between visual dependence and the characteristics of the patients. Many patients with recent hemiplegia seem to rely on visual input. The mechanisms of such visual dependence are discussed. Rehabilitation programs should take into account the possible impairment of sensory organisation and should include exercises to be performed under visual disturbances.

    The Spanish Stroke Group published the "Plan for stroke healthcare delivery" in 2006 with the aim that all stroke patients could receive the same degree of specialised healthcare according to the stage of their disease, independently of where they live, their age, gender or ethnicity. This Plan needs to be updated in order to introduce new developments in acute stroke. A committee of 19 neurologists specialised in neurovascular diseases representing different regions of Spain evaluated previous experience with this Plan and the available scientific evidence according to published literature. The new organised healthcare system must place emphasis on the characteristics of the different care levels with promotion of Reference Stroke Hospitals, set up less restrictive Stroke Code activation criteria that include new therapeutic options, establish new standard measures for endovascular treatment and develop tele-medicine stroke networks. 2010 Sociedad Española de Neurología.

    2017-01-01

    Full Text Available Stroke is considered to be an acute cerebrovascular disease, including ischemic stroke and hemorrhagic stroke. The high incidence and poor prognosis of stroke suggest that it is a highly disabling and highly lethal disease which can pose a serious threat to human health. Nitric oxide (NO, a common gas in nature, which is often thought as a toxic gas, because of its intimate relationship with the pathological processes of many diseases, especially in the regulation of blood flow and cell inflammation. However, recent years have witnessed an increased interest that NO plays a significant and positive role in stroke as an essential gas signal molecule. In view of the fact that the neuroprotective effect of NO is closely related to its concentration, cell type and time, only in the appropriate circumstances can NO play a protective effect. The purpose of this review is to summarize the roles of NO in ischemic stroke and hemorrhagic stroke.

    Background and Purpose Black Americans and residents of the Southeastern United States, are at increased risk of stroke. Diet is one of many potential factors proposed that might explain these racial and regional disparities. Methods Between 2003–2007, the REasons for Geographic and Racial Differences in Stroke (REGARDS) cohort study enrolled 30,239 black and white Americans aged 45 years or older. Dietary patterns were derived using factor analysis and foods from food frequency data. Incident strokes were adjudicated using medical records by a team of physicians. Cox proportional hazards models were used to examine risk of stroke. Results Over 5.7 years, 490 incident strokes were observed. In a multivariable-adjusted analysis, greater adherence to the Plant-based pattern was associated with lower stroke risk (HR=0.71; 95% CI=0.56–0.91; ptrend=0.005). This association was attenuated after addition of income, education, total energy intake, smoking, and sedentary behavior. Participants with a higher adherence to the Southern pattern experienced a 39% increased risk of stroke (HR=1.39; 95% CI=1.05, 1.84), with a significant (p = 0.009) trend across quartiles. Including Southern pattern in the model mediated the black-white risk of stroke by 63%. Conclusions These data suggest that adherence to a Southern style diet may increase the risk of stroke while adherence to a more plant-based diet may reduce stroke risk. Given the consistency of finding a dietary impact on stroke risk across studies, discussing nutrition patterns during risk screening may be an important step in reducing stroke. PMID:24159061

  2. Stroke awareness in the general population: knowledge of stroke risk factors and warning signs in older adults.

    Hickey, Anne

    2009-01-01

    BACKGROUND: Stroke is a leading cause of death and functional impairment. While older people are particularly vulnerable to stroke, research suggests that they have the poorest awareness of stroke warning signs and risk factors. This study examined knowledge of stroke warning signs and risk factors among community-dwelling older adults. METHODS: Randomly selected community-dwelling older people (aged 65+) in Ireland (n = 2,033; 68% response rate). Participants completed home interviews. Questions assessed knowledge of stroke warning signs and risk factors, and personal risk factors for stroke. RESULTS: Of the overall sample, 6% had previously experienced a stroke or transient ischaemic attack. When asked to identify stroke risk factors from a provided list, less than half of the overall sample identified established risk factors (e.g., smoking, hypercholesterolaemia), hypertension being the only exception (identified by 74%). Similarly, less than half identified established warning signs (e.g., weakness, headache), with slurred speech (54%) as the exception. Overall, there were considerable gaps in awareness with poorest levels evident in those with primary level education only and in those living in Northern Ireland (compared with Republic of Ireland). CONCLUSION: Knowledge deficits in this study suggest that most of the common early symptoms or signs of stroke were recognized as such by less than half of the older adults surveyed. As such, many older adults may not recognise early symptoms of stroke in themselves or others. Thus, they may lose vital time in presenting for medical attention. Lack of public awareness about stroke warning signs and risk factors must be addressed as one important contribution to reducing mortality and morbidity from stroke.

    A consecutive series of 103 patients, 58% male with mean age of 62 year (range 40-75 years), admitted with supratentorial stroke in our teaching hospital were studied. All patients had Computer Tomography scan brain done after clinical evaluation and application of Allen stroke score. Computer Tomography Scan confirmed thrombotic stroke in 55 (53%) patients and haemorrhagic stroke in 48 (47%) patients. Out of the 55 patients with definitive thrombotic stroke on Computer Tomography Scan, Allen stroke score suggested infarction in 67%, haemorrhage in 6% and remained inconclusive in 27% of cases. In 48 patients with definitive haemorrhagic stroke on Computer Tomography Scan, Allen stroke score suggested haemorrhage in 60%, infarction in 11% and remained inconclusive in 29% of cases. The overall accuracy of Allen stroke score was 66%. (author)

    Ischemic strokes associated with atrial fibrillation (AF) are more severe than those of other cause. We aim to study potential sex effects in this context. In this cross-sectional study, 74 425 adults with acute ischemic stroke from the Austrian Stroke Unit Registry were included between March 2003 and January 2016. In 63 563 patients, data on the National Institutes of Health Stroke Scale on admission to the stroke unit, presence of AF, vascular risk factors, and comorbidities were complete. Analysis was done by a multivariate regression model. Stroke severity in general increased with age. AF-related strokes were more severe than strokes of other causes. Sex-related differences in stroke severity were only seen in stroke patients with AF. Median (Q 25 , 75 ) National Institutes of Health Stroke Scale score points were 9 (4,17) in women and 6 (3,13) in men ( P stroke severity was independent of age, previous functional status, vascular risk factors, and vascular comorbidities and remained significant in various subgroups. Women with AF do not only have an increased risk of stroke when compared with men but also experience more severe strokes. © 2017 American Heart Association, Inc.

    Stroke is a major cause of disability and health care expenditure around the world. Existing stroke rehabilitation methods can be effective but are costly and need to be improved. Even modest improvements in the effectiveness of rehabilitation techniques could produce large benefits in terms of quality of life. The work reported here is part of an ongoing effort to integrate virtual reality and machine vision technologies to produce innovative stroke rehabilitation methods. We describe a combined object recognition and event detection system that provides real time feedback to stroke patients performing everyday kitchen tasks necessary for independent living, e.g. making a cup of coffee. The image plane position of each object, including the patient"s hand, is monitored using histogram-based recognition methods. The relative positions of hand and objects are then reported to a task monitor that compares the patient"s actions against a model of the target task. A prototype system has been constructed and is currently undergoing technical and clinical evaluation.

    To explore the organized stroke unit experience from the multiple perspectives of stroke survivor, family carer and the multi-disciplinary team. Organized stroke unit care reduces morbidity, mortality and institutionalization and is promoted globally as the most effective form of acute and postacute provision. Little research has focused on how care is experienced in this setting from the perspectives of those who receive and provide care. This study used a qualitative approach, employing Framework Analysis. This methodology allows for a flexible approach to data collection and a comprehensive and systematic method of analysis. Semi-structured interviews were undertaken during 2011 and 2012 with former stroke unit stroke survivors, family carers and senior stroke physicians. In addition, eight focus groups were conducted with members of the multi-disciplinary team. One hundred and twenty-five participants were recruited. Three key themes were identified across all data sets. First, two important processes are described: responses to the impact of stroke and seeking information and stroke-specific knowledge. These are underpinned by a third theme: the challenge in building relationships in organized stroke unit care. Stroke unit care provides satisfaction for stroke survivors, particularly in relation to highly specialized medical and nursing care and therapy. It is proposed that moves towards organized stroke unit care, particularly with the emphasis on reduction of length of stay and a focus on hyper-acute models, have implications for interpersonal care practices and the sharing of stroke-specific knowledge. © 2017 John Wiley & Sons Ltd.

    Objective. The aim of this exploratory pilot study is to test the effects of bilateral tDCS combined with upper extremity robot-assisted therapy (RAT) on stroke survivors. Methods. We enrolled 23 subjects who were allocated to 2 groups: RAT + real tDCS and RAT + sham-tDCS. Each patient underwent 10 sessions (5 sessions/week) over two weeks. Outcome measures were collected before and after treatment: (i) Fugl-Meyer Assessment-Upper Extremity (FMA-UE), (ii) Box and Block Test (BBT), and (iii) Motor Activity Log (MAL). Results. Both groups reported a significant improvement in FMA-UE score after treatment (p robotics on motor function. Patients with chronic and subcortical stroke benefited more from the treatments than patients with acute and cortical stroke, who presented very small changes. Conclusion. The additional use of bilateral tDCS to RAT seems to have a significant beneficial effect depending on the duration and type of stroke. These results should be verified by additional confirmatory studies.

    Training and implementation for a multidisciplinary stroke rehabilitation method emphasizing procedural memory. Current practice in stroke rehabilitation relies on explicit memory, often compromised by stroke, failing to capitalize on better-preserved procedural memory skills. Recruitment of procedural memory requires consistency and practice, characteristics difficulty to promote on inpatient rehabilitation units. We designed a method Modified Approach to Stroke Rehabilitation (MAStR) to maximize consistency and practice for transfer training with stroke patients. Phase I, single-group study. MAStR has two innovations: (1) simplification of instructions to only three words, other direction provided non-verbally; (2) having all rehabilitation staff apply the same approach for transfers. Staff training in MAStR included review of written material describing the rationale for MAStR and demonstration of a transfer using MAStR. Enrolled patients completed each transfer with MAStR in addition to standard rehabilitation therapy. The MAStR method was taught to a large, multidisciplinary rehabilitation staff (n = 31). Training and certification required 15 min per staff member. Five stroke patients were enrolled. No transfers with MAStR resulted in injury, no negative feedback was received from staff or patients. Staff reported satisfaction with the brief MAStR training and reported transfers were easier to complete with the MAStR method. Feasibility was demonstrated for an innovative application of procedural memory concepts to stroke rehabilitation. All rehabilitation disciplines were successfully trained. MAStR was well-tolerated and liked by rehabilitation staff and patients. These results support pursuit of a Phase II pilot study.

    The Singapore National Stroke Association, registered in 1996, offers support and information to stroke survivors and caregivers, and aims to raise public stroke awareness. In the last 20 years, we have developed programs to equip stroke survivors and caregivers with knowledge, life skills, comfort, and opportunities for socialization and reintegration. We have on-going public education and advocacy initiatives. Obtaining funding, member recruitment, volunteer retention, and leadership renewal are on-going challenges. Singapore National Stroke Association will continue to strive for the betterment of stroke survivors, their caregivers, and the public.

    To investigate the association between vertigo and stroke in Taiwan using the Bureau of National Health Insurance research database. Information on adult patients with an index vertigo attack in 2006 was retrieved from Bureau of National Health Insurance research database. All patients with specific diagnostic codes for vertigo were included. Occurrence of stroke during a 1-year follow-up period was identified. Risk factors for stroke were examined. Using χ test, t test, and a multilevel logistic regression model, patients with vertigo were categorized into stroke and nonstroke groups for comparative analyses. An age- and sex- matched control cohort was prepared for comparison. Patients with vertigo (n = 527,807) (mean age, 55.1 yr) accounted for 3.1% of the general Taiwanese adult population. The prevalence of stroke among vertigo patients of 0.5% (mean age, 67.8 yr) was slightly higher than that of the control group (0.3%; mean age, 72.3 yr; p vertigo had higher prevalence of comorbid conditions (p diabetes mellitus, hypertension, dyslipidemia, coronary artery disease, or atrial fibrillation had a higher prevalence of stroke (p vertigo had higher chance to develop stroke than the control group. Some strokes may initially manifest as peripheral vertigo, and some central vertigo may eventually evolve into a stroke. Middle aged male, diabetes, hypertension, dyslipidemia, coronary artery disease, and atrial fibrillation are risk factors for subsequent stroke in vertigo patients.

    Risk factor management is the key to stroke prevention. Although several studies have assessed the awareness of different risk factors in the general public, there are limited data available on how well acute stroke patients know their own risk factors. The aim of this study was to assess stroke patients' informedness of their own stroke risk factors. All consecutive eligible acute stroke and transient ischemic attack patients hospitalized at the Tartu University Hospital, Department of Neurology, during 9 months in 2010 were interviewed about different stroke risk factors within 72 hours from hospitalization. The respective information was also retrieved from medical records. Of the 341 patients admitted during the study period, 195 were eligible for the interview. Diabetes was the best known risk factor (89%) followed by hypertension (80%), atrial fibrillation (78%), previous stroke (77%), and heart failure and/or ischemic heart disease (66%). We found that acute stroke patients are best informed of their diabetes and worst informed of their ischemic heart disease and/or heart failure. There is, however, room for amelioration in the awareness of all of the studied risk factors. More attention should be addressed to explaining the risks and treatment options to patients at risk of stroke and the general population. Copyright © 2016 National Stroke Association.

    Background Spanish is the second most spoken language in the world. Spanish-speaking populations (SSP) have heterogeneous cultural backgrounds, racial and ethnical origins, economic status, and access to health care systems. There are no published reviews about stroke knowledge in SSP. We reviewed the existing literature addressing stroke knowledge among SSP and propose future directions for research. Summary We identified 18 suitable studies by searching PubMed, Lilacs, Scopus, Embase, Cochrane and Scielo databases, and looking at reference lists of eligible articles. We also included 2 conference abstracts. Data related to stroke knowledge from studies of Spanish-speakers was analyzed. Key messages Little is known about stroke knowledge in SSP, especially in Latin America. Information is poor even among subjects at risk, stroke patients, stroke survivors, and health care providers. “Ictus”, the word used for stroke in Spanish, is largely unrecognized among subjects at risk. Furthermore, access to medical care and presence of neurologists are suboptimal in many regions. There are several potential issues to solve regarding stroke knowledge and stroke care in SSP. Programs to educate the general population and non-neurologists medical providers in stroke and telemedicine may be suitable options to improve the present situation. PMID:25871697

    Full Text Available Background and purposeThe blood–brain barrier (BBB not only provides a physical obstruction but also recruits and activates neutrophils in cases of infection. Hemorrhagic or ischemic stroke reportedly induces the disruption of the BBB. However, few studies have reported a correlation between the incidence of meningitis in patients with a history of stroke. This study tested the hypothesis that patients with a history of stroke may be more vulnerable to meningitis.MethodsStroke and age-matched comparison (n = 29,436 and 87,951, respectively cohorts were recruited from the Taiwan National Health Insurance database (2000–2011. Correlations between the two cohorts were evaluated by Cox proportional hazard regression model, Kaplan–Meier curve, and log-rank tests.ResultsThe incidence of meningitis was higher in the stroke cohort compared to that in the comparison cohort [hazard ratio (HR, 2.89; 95% confidence interval (CI, 2.23–3.74, p < 0.001]. After adjusting for age, sex, and comorbidities, the estimated HR in the stroke cohort was 2.55-fold higher than that in the comparison cohort (CI, 1.94–3.37; p < 0.001. Notably, patients who had experienced hemorrhagic stroke had a higher incidence rate of meningitis than those with a history of ischemic stroke, except for patients older than 75 years (incidence rates in hemorrhagic/ischemic stroke patients, 3.14/1.48 in patients younger than 45 years, 1.52/0.41 in 45- to 64-year group, 1.15/0.90 in 65- to 74-year group, 0.74/0.93 in patients older than 75 years. Moreover, stroke patients who had undergone head surgery had the highest meningitis risk (adjusted HR, 8.66; 95% CI, 5.55–13.5; p < 0.001 followed by stroke patients who had not undergone head surgery (adjusted HR, 2.11; 95% CI, 1.57–2.82; p < 0.001.ConclusionOur results indicated that stroke patients have higher risks of meningitis. Compromised BBB integrity in stroke patients may lead to increased

    To compare serum lipid profile between patients of ischaemic and haemorrhagic strokes. Study Design: Cross sectional, comparative study. Place and Duration of Study: Military Hospital, Rawalpindi, from August 2004 to February 2005. Methodology: Patients with diagnosis of stroke comprising 100 consecutive patients each of ischaemic and haemorrhagic strokes were included in the study while patients on lipid lowering therapy were excluded from study. To determine the subtype of stroke, clinical examination followed by CT scan of brain was done. A serum sample after 8 hours of overnight fasting was taken on the next day of admission for both groups of patients. Total serum cholesterol, triglycerides, LDL cholesterol, VLDL-cholesterol and HDL-cholesterol was determined, using enzymatic colorimetric method. Statistical analysis was done by comparison of lipid profile in two subgroups, using proportion test for any significant difference. Results: The mean age at presentation of patients with stroke was 64.2+-12 years with a male to female ratio of 3.6:1. In 100 ischaemic stroke patients, raised serum total cholesterol was seen in 42, triglyceride in 04, LDL-cholesterol in 05 and VLDL-cholesterol in 07 patients. Serum HDL-cholesterol was below the normal reference in 31 cases. On the other hand, serum total cholesterol and triglycerides was raised in 05 patients each, LDL-cholesterol in 09 and VLDL-cholesterol in 03 patients of haemorrhagic stroke. Serum HDL-cholesterol was below normal in 04 patients of haemorrhagic stroke. On comparison, there were significantly greater number of patients with raised serum cholesterol and low HDL-cholesterol in ischaemic stroke than haemorrhagic stroke (p < 0.05). No statistical significance was found on comparing serum values of ischaemic and haemorrhagic stroke for triglycerides, LDL-cholesterol and VLDL-cholesterol. Conclusion: Ischaemic stroke patients had high serum total cholesterol and lower HDL-cholesterol levels as compared to

    PURPOSE: The purpose of the study was to assess polysomnographic indicators of increased mortality risk in patients with stroke or a transient ischemic attack (TIA). METHODS: We performed polysomnographies in 63 acute stroke/TIA patients. Mortality data were collected from a national database after...... a 19-37-month follow-up period. RESULTS: Of the 57 stroke and 6 TIA patients, 9 stroke patients died during follow-up. All nine had moderate or severe sleep-related breathing disorders (SRBDs). Binarily divided, the group with the highest apnea hypopnea index (AHI) had an almost 10-fold higher...... mortality risk (hazard ratio (HR) 9.71; 95 % confidence interval (CI) 1.20-78.29; p = 0.033) compared to the patients with the lowest AHI. The patients with the longest versus shortest nocturnal wake time had a higher mortality (HR 8.78; 95 % CI 1.1-71.8; p = 0.0428). Lung disease increased mortality (HR 9...

    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 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 Stroke Organization.

    We aimed to assess the risk of recurrent ischemic events during hospitalization for stroke or transient ischemic attack (TIA) with optimal current management and to identify associated risk factors. We performed a retrospective analysis of all patients treated for acute ischemic stroke or TIA in 3 stroke units between 2010 and 2013. Recurrent stroke was defined as new persisting (≥24 hours) neurological deficit occurring >24 hours after the index event and not attributable to other causes of neurological deterioration. Cox proportional hazard regression identified risk factors associated with recurrent stroke. The study included 5106 patients. During a median length of stay of 5 days (interquartile range, 4-8), stroke recurrence (or stroke after TIA) occurred in 40 patients (0.8%) and was independently associated with history of TIA, symptomatic carotid stenosis (≥70%), or other determined etiology. Patients with recurrent stroke and other determined etiology had cervical arterial dissection (n=2), primary angiitis of the central nervous system (n=1), giant cell arteritis (n=1), and lung cancer with nonbacterial thrombotic endocarditis (n=1). In patients with initial TIA or minor stroke (National Institutes of Health Stroke Scale ≤5) recurrence was associated additionally with pneumonia after the inciting ischemic event but before stroke recurrence. Patients with initial stroke and aphasia had a lower stroke recurrence rate and there were no recurrences in patients with lacunar stroke. Recurrence was associated with significantly higher in-hospital mortality (17.5% versus 3.1%; Pstroke recurrence was low with optimal current management. Patients with a history of TIA, severe symptomatic carotid stenosis, or uncommon causes of stroke were at higher risk. Pneumonia was associated with a higher risk of stroke recurrence in patients with initial TIA or minor stroke but not in the overall population studied. Aphasia may bias the detection rate by concealing new

    Stroke is the fifth leading cause of death and the leading cause of serious long-term adult disability in the US. Acute stroke treatments with intravenous thrombolysis and endovascular therapy are proven to reduce disability, however a critical limitation on their effectiveness is the narrow time window for administration, which is 4.5 hours and 6 hours respectively from the onset of symptoms. Our overarching goal is to reduce pre-hospital delays to acute stroke treatments in economically disadvantaged minority communities where the greatest delays exist, using Hip Hop Stroke. Hip Hop Stroke (HHS) is a school-based, child-mediated, culturally-tailored stroke communication multimedia intervention developed using validated models of behavior change and designed to improve stroke literacy (knowledge of stroke symptoms, the urgent need to call 911, and prevention measures) of 4 th , 5 th and 6 th grade students and their parents residing in poor urban communities. Children in the intervention arm will receive the HHS intervention, while those in the attentional control arm will receive standardized nutrition education based on the USDA's MyPyramid program. Children will be trained and motivated to share stroke information with their parents or other adult caregiver. Both children and parents will complete a stroke knowledge assessment at baseline, immediately following the program, and at 3-months post-program. The primary outcome is the effect of the child mediation on parental stroke literacy. Stroke literate children, a captive audience in school systems, may represent a viable channel for spreading stroke information into households of poor urban communities where mass media stroke campaigns have shown the lowest penetration. These children may also call 911 when witnessing a stroke in their homes or communities. The HHS program may highlight the potential role of children in the chain of stroke recovery as a strategy for reducing prehospital delays to acute stroke

    Stroke diagnosis could be challenging in the acute phase. We aimed to develop a blood-based diagnostic tool to differentiate between real strokes and stroke mimics and between ischemic and hemorrhagic strokes in the hyperacute phase. The Stroke-Chip was a prospective, observational, multicenter study, conducted at 6 Stroke Centers in Catalonia. Consecutive patients with suspected stroke were enrolled within the first 6 hours after symptom onset, and blood samples were drawn immediately after admission. A 21-biomarker panel selected among previous results and from the literature was measured by immunoassays. Outcomes were differentiation between real strokes and stroke mimics and between ischemic and hemorrhagic strokes. Predictive models were developed by combining biomarkers and clinical variables in logistic regression models. Accuracy was evaluated with receiver operating characteristic curves. From August 2012 to December 2013, 1308 patients were included (71.9% ischemic, 14.8% stroke mimics, and 13.3% hemorrhagic). For stroke versus stroke mimics comparison, no biomarker resulted included in the logistic regression model, but it was only integrated by clinical variables, with a predictive accuracy of 80.8%. For ischemic versus hemorrhagic strokes comparison, NT-proBNP (N-Terminal Pro-B-Type Natriuretic Peptide) >4.9 (odds ratio, 2.40; 95% confidence interval, 1.55-3.71; P 4.7 (odds ratio, 2.02; 95% confidence interval, 1.19-3.45; P =0.010), together with age, sex, blood pressure, stroke severity, atrial fibrillation, and hypertension, were included in the model. Predictive accuracy was 80.6%. The studied biomarkers were not sufficient for an accurate differential diagnosis of stroke in the hyperacute setting. Additional discovery of new biomarkers and improvement on laboratory techniques seem necessary for achieving a molecular diagnosis of stroke. © 2017 American Heart Association, Inc.

    The European Hypothermia Stroke Research Workshop was held in January 2010, in response to the alarming prospects of a significant increase of stroke expected in the coming years globally. Considering that a minority of patients (around 10%) are currently eligible for thrombolytic treatment, there is a need for an efficacious, cost-effective novel therapy that can be implemented broadly within European health care systems. Accordingly, the primary objective of the workshop was the definition of a research agenda aiming to assess the therapeutic benefits of hypothermia in patients with acute ischaemic stroke. The meeting was organised by the European Stroke Research Network for Hypothermia (EuroHyp) and attended by the representatives of World Stroke Organisation, European Stroke Organisation, Stroke Alliance for Europe, Society for Cryobiology and other organisations--specifically the European Space Agency, and small- and medium-sized enterprises based in EU member states. The participants adopted the 'Hypothermia for Stroke--Call to Action 2010', a declaration specifying the priorities for hypothermia research in acute ischaemic stroke. The research programme outlined--a clinical study programme designed to identify and validate therapeutic cooling as a novel treatment providing benefit to a large number of stroke patients--contains a well-integrated series of Phase II studies aiming to refine the intervention (depth, duration, and mode of cooling; antishivering strategy; patient selection) and a pivotal Phase III clinical trial. The proposed integrated Phase II and III clinical study programme would test the effectiveness of this optimised intervention, and would allow the development of evidence-based Clinical Practice Guidelines describing the optimal use of therapeutic hypothermia as a treatment strategy for stroke. © 2010 The Authors.

    This study evaluated whether mild stroke patients who received a community-based stroke nursing intervention had better stroke knowledge, behaviour and self-efficacy than those who were exposed to traditional education programmes. The intervention group consisted of sixty five stroke patients randomly selected from seven communities who received three 2-hour stroke interventions per week for 8 weeks. The normal care group consisted of sixty two stroke patients randomly selected from a medical centre who received a general stroke education programme. The stroke patients in two groups were assessed at baseline, after intervention and at the 6-month follow-up. At the 6-month follow-up, the intervention group demonstrated an improvement in the knowledge of stroke risk factors compared with the normal care group. Three months after education, the intervention group exhibited changes in the knowledge of stroke, social participation and self-efficacy compared with those at baseline. Also, self-efficacy was correlated with the knowledge of stroke risk factors after intervention and at the 6-month follow-up; self-efficacy was correlated with social participation after the 6-month follow-up. A community-based stroke nursing intervention might have effects on changes in the knowledge of stroke risk factors, social participation and self-efficacy. © 2013 Wiley Publishing Asia Pty Ltd.

    The mean velocity of 9 out of 10 women's events during the U.S. Olympic Swimming Trials was greater in 1984 as compared to 1976. Three of the 10 men's events showed improvement. In 9 out of these 12 events, the increased velocity was accounted for by increased distance per stroke (range, -3 to -13%). In the women's 100-m butterfly and 100-m backstroke, increased velocity was due solely to faster stroke rates. The finalists in each event were compared to those whose velocities were 3-7% slower. In almost all events and stroke styles, the finalists achieved greater distances per stroke than did the slower group. In the men's events increased distance per stroke was associated with decreased stroke rate, except in the backstroke, in which both were increased for the finalists. Although the faster women swimmers generally had greater distances per stroke, they were more dependent than men on faster stroke rates to achieve superiority. The profile of velocity for races of 200 m and longer indicated that as fatigue developed the distance per stroke decreased. The faster swimmers compensated for this change by maintaining or increasing stroke rate more than did their slower competitors. This study indicates that improvements and superiority in stroke mechanics are reflected in the stroke rate and distance per stroke used to swim a race.

    Stroke is the leading cause of death in women and the third leading cause in men in France. In young adults (ie, 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 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.

    Tandem occlusive disease in the setting of acute ischemic stroke involving cervical and cerebral arteries has been associated with poor neurological outcome and poses significant challenges to neurointerventionists. Previously described endovascular methods typically involve carotid revascularization with stent placement prior to or following intracranial thrombectomy. Stent-based approaches, however, require the use of antiplatelet therapy which may increase the risk of hemorrhagic transformation. We describe a novel modified Dotter technique which may be used for carotid revascularization in lieu of stenting. This technique can eliminate the need for antiplatelet therapy, reduce procedure times, and possibly reduce hemorrhagic conversion rates. Seven patients presenting between April 2013 and January 2014 were treated with this technique. All patients had carotid stenosis of 65-100% and tandem middle cerebral artery occlusions. National Institutes of Health (NIH) Stroke Scale scores as well as clinical and procedural times were recorded. Pre- and post-Dotter stenosis was measured using the NASCET criteria. Follow-up imaging and clinical data were reviewed. The mean age was 64 years and mean initial NIH Stroke Scale score was 11.7. Mean groin to recanalization time was 26 min. Thrombolysis In Cerebral Infarction grade 2b-3 was achieved in all patients. The mean stenosis was 88% preoperatively and 61% postoperatively. There were no intracranial hemorrhages. The modified Rankin Scale score was 0 in six patients (86%) and 6 in one patient (14%). The Dotter stroke technique is a feasible and safe alternative to carotid stenting in the setting of acute ischemic stroke and may reduce the risk of hemorrhagic conversion. No re-occlusion occurred during follow-up in patients with post-Dotter stenosis ≤65%. Published by the BMJ Publishing Group Limited.

    Kolja M Thierfelder

    Full Text Available BACKGROUND AND PURPOSE: While penumbra assessment has become an important part of the clinical decision making for acute stroke patients, there is a lack of studies measuring the reliability and reproducibility of defined assessment techniques in the clinical setting. Our aim was to determine reliability and reproducibility of different types of three-dimensional penumbra assessment methods in stroke patients who underwent whole brain CT perfusion imaging (WB-CTP. MATERIALS AND METHODS: We included 29 patients with a confirmed MCA infarction who underwent initial WB-CTP with a scan coverage of 100 mm in the z-axis. Two blinded and experienced readers assessed the flow-volume-mismatch twice and in two quantitative ways: Performing a volumetric mismatch analysis using OsiriX imaging software (MM(VOL and visual estimation of mismatch (MM(EST. Complementarily, the semiquantitative Alberta Stroke Programme Early CT Score for CT perfusion was used to define mismatch (MM(ASPECTS. A favorable penumbral pattern was defined by a mismatch of ≥ 30% in combination with a cerebral blood flow deficit of ≤ 90 ml and an MM(ASPECTS score of ≥ 1, respectively. Inter- and intrareader agreement was determined by Kappa-values and ICCs. RESULTS: Overall, MM(VOL showed considerably higher inter-/intrareader agreement (ICCs: 0.751/0.843 compared to MM(EST (0.292/0.749. In the subgroup of large (≥ 50 mL perfusion deficits, inter- and intrareader agreement of MM(VOL was excellent (ICCs: 0.961/0.942, while MM(EST interreader agreement was poor (0.415 and intrareader agreement was good (0.919. With respect to penumbra classification, MM(VOL showed the highest agreement (interreader agreement: 25 agreements/4 non-agreements/κ: 0.595; intrareader agreement 27/2/0.833, followed by MM(EST (22/7/0.471; 23/6/0.577, and MM(ASPECTS (18/11/0.133; 21/8/0.340. CONCLUSION: The evaluated approach of volumetric mismatch assessment is superior to pure visual and ASPECTS penumbra

The material for the study was the medical history of 31 pregnant women with diagnosis ACCI. The average age was 29,5 ± 5,1 years. The comparison group consisted of pregnant women with physiological pregnancy (n = 30 with different gestation periods, the mean age was 29,1 ± 6,7 years. In this study, a comparative analysis of risk factors for stroke was carried out: gynecological and allergic history, smoking and taking contraceptives, the presence of chronic diseases, indicators of the hemostasis and lipid spectrum, polymorphism of thrombophilia genes.Results. The prevalence of ischemic stroke over hemorrhagic stroke was found, which was 77.4% and 22.6%, respectively. In 93.5% of cases, a stroke occurred during pregnancy, in 79.3% of them in the third trimester of gestation. The number of recuperated women was 67.7%. As a result of statistical treatment, a significant difference in study and comparison groups was obtained (p < 0.05 as a result of a burdened obstetric-gynecological history.

    The Irish Heart Foundation carried out the Irish National Audit of Stroke Care (INASC) in 2008. Management practices were significantly poorer than those in the UK Sentinel audits. Since then an acute stroke unit has been established in University Hospital Limerick. A stroke database was established. 12 key indicators of stroke management audited by INASC were identified. Results were compared to those in INASC. 89 stroke patients were admitted. 8 of the 12 key indicators scored significantly better than in INASC. 92.5% had a brain scan within 24hrs (INASC-40%, p = strokes received anti-thrombotics (INASC-85%, p = 0.001). 94% had rehab goals agreed by MDT (22% in INASC p = 0.0000). 55% were treated in stroke unit (2% in INASC, p = 0.0000). MDT input improved with regard to physiotherapy (87% vs 43% in INASC, p = Stroke management has significantly improved from 2008, however some deficiencies remain.

    2012-06-01

    Full Text Available CONTEXT: Stroke is a frequent cause of dysphagia. OBJECTIVE: To evaluate in a tertiary care hospital the prevalence of swallowing dysfunction in stroke patients, to analyze factors associated with the dysfunction and to relate swallowing dysfunction to mortality 3 months after the stroke. METHODS: Clinical evaluation of deglutition was performed in 212 consecutive patients with a medical and radiologic diagnosis of stroke. The occurrence of death was determined 3 months after the stroke. RESULTS: It was observed that 63% of the patients had swallowing dysfunction. The variables gender and specific location of the lesion were not associated with the presence or absence of swallowing dysfunction. The patients with swallowing dysfunction had more frequently a previous stroke, had a stroke in the left hemisphere, motor and/or sensitivity alterations, difficulty in oral comprehension, alteration of oral expression, alteration of the level of consciousness, complications such as fever and pneumonia, high indexes on the Rankin scale, and low indexes on the Barthel scale. These patients had a higher mortality rate. CONCLUSIONS: Swallowing evaluation should be done in all patients with stroke, since swallowing dysfunction is associated with complications and an increased risk of death.

    Background and Purpose Lower plasma magnesium levels may be associated with higher blood pressure and endothelial dysfunction, but sparse prospective data are available for stroke. Methods Among 32,826 participants in the Nurses’ Health Study who provided blood samples in 1989–1990, incident ischemic strokes were identified and confirmed by medical records through 2006. We conducted a nested case-control analysis of 459 cases, matched 1:1 to controls on age, race/ethnicity, smoking status, date of blood draw, fasting status, menopausal status and hormone use. We used conditional logistic regression models to estimate the multivariable adjusted association of plasma magnesium and the risk of ischemic stroke and ischemic stroke subtypes. Results Median magnesium levels did not differ between ischemic stroke cases and controls (median=0.86 mmol/l for both; p-value=0.14). Conditional on matching factors, women in the lowest magnesium quintile had a relative risk (RR) of 1.34 (95% confidence interval [CI]: 0.86–2.10, p trend=0.13) for total ischemic stroke, compared to women in the highest quintile. Additional adjustment for risk factors and confounders did not substantially alter the risk estimates for total ischemic stroke. Women with magnesium levels magnesium levels ≥0.82 mmol/l. No significant effect modification was observed by age, body mass index, hypertension or diabetes. Conclusions Lower plasma magnesium levels may contribute to higher risk of ischemic stroke among women. PMID:25116874

    Post-stroke language disorders are frequent and include aphasia, alexia, agraphia and acalculia. There are different definitions of aphasias, but the most widely accepted neurologic and/or neuropsychological definition is that aphasia is a loss or impairment of verbal communication, which occurs as a consequence of brain dysfunction. It manifests as impairment of almost all verbal abilities, e.g., abnormal verbal expression, difficulties in understanding spoken or written language, repetition, naming, reading and writing. During the history, many classifications of aphasia syndromes were established. For practical use, classification of aphasias according to fluency, comprehension and abilities of naming it seems to be most suitable (nonfluent aphasias: Broca's, transcortical motor, global and mixed transcortical aphasia; fluent aphasias: anomic, conduction, Wernicke's, transcortical sensory, subcortical aphasia). Aphasia is a common consequence of left hemispheric lesion and most common neuropsychological consequence of stroke, with a prevalence of one-third of all stroke patients in acute phase, although there are reports on even higher figures. Many speech impairments have a tendency of spontaneous recovery. Spontaneous recovery is most remarkable in the first three months after stroke onset. Recovery of aphasias caused by ischemic stroke occurs earlier and it is most intensive in the first two weeks. In aphasias caused by hemorrhagic stroke, spontaneous recovery is slower and occurs from the fourth to the eighth week after stroke. The course and outcome of aphasia depend greatly on the type of aphasia. Regardless of the fact that a significant number of aphasias spontaneously improve, it is necessary to start treatment as soon as possible. The writing and reading disorders in stroke patients (alexias and agraphias) are more frequent than verified on routine examination, not only in less developed but also in large neurologic departments. Alexia is an acquired

    On the basis of 100 findings from patients who suffered brain strokes and by the use of 1500 ensured stroke images it was tested whether or not the stroke-predilection typologie outlined by Zuelch is based on a coincidental summation of individual cases. The radio-computed tomography with the possibility of evaluation of non-lethal cases proved itself as a suited method for confirmation or repudiation of this stroke theory. By means of the consistently achieved association of the frontal, respectively horizontal sectional image for the typology it could be proven and - with the exception of a few rather seldom types - also demonstrated that the basic and predilection types of brain stroke repeated themselves in their pattern. In individual cases a specification of lower types could also be undertaken. (orig./TRV) [de

  20. MIGRAINE AND STROKE: VASCULAR COMORBIDITY

    Directory of Open Access Journals (Sweden)

    2014-10-01

    Full Text Available Several comorbidities are associated to migraine.Recent meta-analyses have consistently demonstrated a relationship between migraine and stroke, which is well-defined for ischaemic stroke and migraine with aura, even stronger in females on oral contraceptives or smokers. However, there seems to be no clear-cut association between stroke in migraineurs and the common vascular risk factors, at least in the young adult population. Migraineurs also run an increased risk of hemorrhagic stroke, while the association between migraine and cardiovascular disease remains poorly defined.Another aspect is the relationship between migraine and the presence of silent brain lesions. It has been demonstrated that there is an increased frequency of ischaemic lesions in the white matter of migraineurs, especially silent infarcts in the posterior circulation territory in patients with at least 10 attacks per month. Although there is a higher prevalence of patent foramen ovale (PFO in migraineurs, the relationship between migraine and PFO remains controversial and PFO closure is not a recommended procedure to prevent migraine. As an increased frequency of cervical artery dissections has been observed in migrainous patients, it has been hypothesized that migraine may represent a predisposing factor for cervical artery dissection. There still remains the question as to whether migraine should be considered a true vascular disease or if the comorbidity between migraine and cerebrovascular disease may have underlying shared risk factors or pathophysiological mechanisms. Although further studies are required to clarify this issue, current evidence supports a clinical management where MA patients should be screened for other concomitant vascular risk factors and treated accordingly.

    Full Text Available Endovascular therapy (EVT has gained vogue in the management of patients with acute stroke. Newer stent-retriever devices have led to better recanalization rates. In many centers, EVT is slowly being used as an add on to or in some instances, even as an alternative to intravenous tissue plasminogen activator (IV tPA. The publication of the results of the SYNTHESIS expansion, Interventional Management of Stroke III and Mechanical Retrieval Recanalization of Stroke Clots Using Embolectomy trials in 2013 has questioned the enthusiastic use of EVT in acute stroke. They demonstrate that EVT (using a variety of devices is no superior to IV tPA in the management of acute stroke. In the light of these controversial findings, we review the current status of EVT in the management of acute stroke.

    The standard for stroke risk stratification is the Framingham Stroke Risk Function (FSRF), an equation requiring an examination for blood pressure assessment, venipuncture for glucose assessment, and ECG to determine atrial fibrillation and heart disease. We assess a self-reported stroke risk function (SRSRF) to stratify stroke risk in comparison to the FSRF. Participants from the REGARDS study (Reasons for Geographic and Racial Differences in Stroke) were evaluated at baseline and followed for incident stroke. The FSRF was calculated using directly assessed stroke risk factors. The SRSRF was calculated from 13 self-reported questions to exclude those with prevalent stroke and assess stroke risk. Proportional hazards analysis was used to assess incident stroke risk using the FSRF and SRSRF. Over an average 8.2-year follow-up, 939 of 23 983 participants had a stroke. The FSRF and SRSRF produced highly correlated risk scores ( r Spearman =0.852; 95% confidence interval, 0.849-0.856); however, the SRSRF had higher discrimination of stroke risk than the FSRF (c SRSRF =0.7266; 95% confidence interval, 0.7076-0.7457; c FSRF =0.7075; 95% confidence interval, 0.6877-0.7273; P =0.0038). The 10-year stroke risk in the highest decile of predicted risk was 11.1% for the FSRF and 13.4% for the SRSRF. A simple self-reported questionnaire can be used to identify those at high risk for stroke better than the gold standard FSRF. This instrument can be used clinically to easily identify individuals at high risk for stroke and also scientifically to identify a subpopulation enriched for stroke risk. © 2017 American Heart Association, Inc.

  7. Stroke in Asia: a global disaster.

    Science.gov (United States)

    Kim, Jong S

    2014-10-01

    Although stroke is a world-wide problem, the burden of stroke is particularly serious in Asia; its mortality is higher than in Europe or North America. The situation in Asia is dichotomized. Stroke mortality and case fatality has been declining in northern-eastern countries such as Korea, Japan, Taiwan, and urbanized areas of China. This is attributed to both the risk factor control and stroke care improvement. However, declining stroke incidence is rarely observed, which is in part due to rapidly aging population. As a result, there is an increase in the number of stroke survivors who require long-term, costly care. The extremely low birth rate and relatively insecure social health system markedly increases the caregiver burden. The problem in southern Asian countries, such as India, Pakistan, Bangladesh, and Indonesia is more fundamental. With the improving control of infectious diseases, life expectancy is prolonged. However, risk factors such as hypertension, diabetes, obesity and cigarette smoking become prevalent, and are poorly controlled. Stroke neurologists, organized stroke centers, and diagnostic tools are insufficient, which has resulted in high stroke fatality and mortality. Throughout Asia, the most urgent priority should be the primary stroke prevention through promoting a healthy lifestyle, e.g. low salt intake, regular physical exercise, stopping smoking, government sectors should take a stronger initiative to accomplish this. The rapidly aging populations and stroke burden will shrink the economy and destabilize the society, not only in Asia but also globally unless appropriate efforts are promptly initiated, this may result in a global disaster. © 2014 World Stroke Organization.

    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.

    Objectives Risk modification through behavior change is critical for primary and secondary stroke prevention. Theories of health behavior identify perceived risk as an important component to facilitate behavior change; however, little is known about perceived risk of vascular events among stroke survivors. Methods The SWIFT (Stroke Warning Information and Faster Treatment) study includes a prospective population-based ethnically diverse cohort of ischemic stroke and transient ischemic attack survivors. We investigate the baseline relationship between demographics, health beliefs, and knowledge on risk perception. Regression models examined predictors of inaccurate perception. Results Only 20% accurately estimated risk, 10% of the participants underestimated risk, and 70% of the 817 study participants significantly overestimated their risk for a recurrent stroke. The mean perceived likelihood of recurrent ischemic stroke in the next 10 years was 51 ± 7%. We found no significant differences by race-ethnicity with regard to accurate estimation of risk. Inaccurate estimation of risk was associated with attitudes and beliefs [worry (p risk factors. Conclusion This paper provides a unique perspective on how factors such as belief systems influence risk perception in a diverse population at high stroke risk. There is a need for future research on how risk perception can inform primary and secondary stroke prevention. Copyright © 2011 S. Karger AG, Basel PMID:21894045

    Full Text Available The new clinical construct of embolic stroke of undetermined source (ESUS suggests that many cryptogenic strokes are related to minor-risk covert embolic cardiac sources or to embolus from non-occlusive plaques in the aortic arch or in the cerebral arteries. The authors analyzed the prevalence of ESUS in a real-life condition in Italy and compared the recurrence rates in cryptogenic strokes, cardioembolic strokes, and ESUS. The authors retrospectively reassessed according to ESUS criteria 391 consecutive admissions in a stroke unit where extensive diagnostic search was routinely performed. Recurrences in each stroke type within a 3-year follow-up period (mean time: 25.44 months - standard deviation: 9.42 were also compared. The prevalence of ESUS in the aforementioned cohort was 10.5%. All ESUS patients received antiplatelet agents. Warfarin was prescribed in 56.9% of cardioembolic strokes. The recurrence rate in ESUS patients was 4.4% per year, slightly higher than in cardioembolic strokes (3.5% and significantly higher than in cryptogenic non-ESUS (1.2% (P<0.0001. This is the first description of a cohort of ESUS patients in an Italian stroke unit. Patients with ESUS have a significantly higher risk of recurrence than in those with non-ESUS cryptogenic strokes, and slightly higher than in those with cardioembolic strokes. Results support the hypothesis of a more extensive diagnostic evaluation in cryptogenic strokes and the feasibility of such approach.

    Factor V Leiden (FVL) has been associated with ischemic stroke in children but not in adults. Although the FVL mutation is associated with increased risk for venous thrombosis, its association with ischemic stroke in young adults remains uncertain. Therefore, we examined the association between FVL and ischemic stroke in participants of the Genetics of Early Onset Stroke (GEOS) study. A population-based case control study identified 354 women and 476 men 15 to 49 years of age with first-ever ischemic stroke and 907 controls. Participant-specific data included vascular risk factors, FVL genotype and, for cases, the ischemic stroke subtype by modified Trial of ORG 10172 in Acute Stroke criteria. Logistic regression was used to calculate odds ratios for the entire population and for subgroups stratified by risk factors and ischemic stroke subtype. The frequency of the FVL mutation was similar between ischemic stroke patients (3.6%; 95% confidence interval [CI] 2.5%-5.1%) and nonstroke controls (3.8%; 95% CI 2.7%-5.2%). This frequency did not change significantly when cases were restricted to patients with stroke of undetermined etiology (4.1%; 95% CI 2.6%-6.4%). Among young adults, we found no evidence for an association between FVL and either all ischemic stroke or the subgroup with stroke of undetermined etiology. Published by Elsevier Inc.

    Full Text Available Noonan syndrome is an autosomal dominant genetic disease characterized by short stature, webbed neck, typical facial appearance and congenital heart disease. Here we report a 24 year old woman patient with the diagnosis of Noonan syndrome who admitted to our clinic with ischemic stroke caused by atrial fibrillation secondary to hypertrophic cardiomyopathy. Noonan syndrome patients with stroke due to vascular malformations have been reported, but non-obstructive hypertrophic cardiomyopathy is a rare cause for stroke in patients with Noonan syndrome. Our aim of presenting the case emphasize that Noonan syndrome should be thought as a differential diagnosis in patients with stroke at a young age and dysmorphic facial appearance.

    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

  10. In-hospital stroke: characteristics and outcomes.

    2015-01-01

    In-hospital stroke (IS) made up 6.5% of strokes recorded in the Irish National Stroke Register in 2012. International research has demonstrated poorer outcomes post IS compared to out of hospital stroke (OS). We aimed to profile all IS and OS over a 22 month period and compare the two groups by gathering data from the HIPE portal stroke register. The study site is a primary stroke centre. IS represented 11% (50\\/458) of total strokes with over half (27\\/50, 54%) admitted initially with medical complaints. IS patients had a significantly longer length of stay (79.2 +\\/- 87.4 days vs. 21.9 +\\/- 45.9 days, p < 0.01) and higher mortality (13\\/50 vs. 39\\/408, p < 0.01). Patients in the IS group were also less likely to receive stroke unit care (1\\/50 vs. 136\\/408, p < 0.01). This study demonstrates the significant morbidity and mortality associated with IS and highlights the need for efforts to be made to optimize identification and management of acute stroke in this cohort.

  12. Stroke rehabilitation reaches a threshold.

    Directory of Open Access Journals (Sweden)

    2008-08-01

    Full Text Available Motor training with the upper limb affected by stroke partially reverses the loss of cortical representation after lesion and has been proposed to increase spontaneous arm use. Moreover, repeated attempts to use the affected hand in daily activities create a form of practice that can potentially lead to further improvement in motor performance. We thus hypothesized that if motor retraining after stroke increases spontaneous arm use sufficiently, then the patient will enter a virtuous circle in which spontaneous arm use and motor performance reinforce each other. In contrast, if the dose of therapy is not sufficient to bring spontaneous use above threshold, then performance will not increase and the patient will further develop compensatory strategies with the less affected hand. To refine this hypothesis, we developed a computational model of bilateral hand use in arm reaching to study the interactions between adaptive decision making and motor relearning after motor cortex lesion. The model contains a left and a right motor cortex, each controlling the opposite arm, and a single action choice module. The action choice module learns, via reinforcement learning, the value of using each arm for reaching in specific directions. Each motor cortex uses a neural population code to specify the initial direction along which the contralateral hand moves towards a target. The motor cortex learns to minimize directional errors and to maximize neuronal activity for each movement. The derived learning rule accounts for the reversal of the loss of cortical representation after rehabilitation and the increase of this loss after stroke with insufficient rehabilitation. Further, our model exhibits nonlinear and bistable behavior: if natural recovery, motor training, or both, brings performance above a certain threshold, then training can be stopped, as the repeated spontaneous arm use provides a form of motor learning that further bootstraps performance and

    Full Text Available 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

    Full Text Available Background: Stroke is a devastating disease with increasing incidence and prevalence due to population aging. Even with the best care, a proportion of patients dies or is left with significant neurological and cognitive disability. Organization of stroke centers markedly improved outcomes worldwide. We initiated a ‘lysis alarm' program in September 2013 at our medical center. Methods: This is a retrospective review of electronic data from patients with acute ischemic stroke before (October 2012-June 2013 and after (October 2013-June 2014 the ‘lysis alarm' program was introduced at our medical center. Results: Prior to the introduction of the stroke program, there were only 19 thrombolysis procedures in 777 acute stroke patients in 9 months, while this figure rose to 32 thrombolysis procedures in 737 acute stroke patients after the initiation of the program. The ‘door-to-needle' time decreased from 88 to 71 min when the two study periods were compared. These changes were associated with decreased stroke mortality in patients receiving thrombolytic treatment (16% prior to the program and 9% during the program. In 2013, there were 1,439 thrombolysis procedures, representing 3.2% of all stroke cases throughout Hungary. After the introduction of the ‘lysis alarm' program, we have reached a 4% thrombolysis rate at our medical center. Conclusions: Our thrombolysis rate is higher than the national average, but still low compared to the rates of Western European countries. We are continuously working to enhance our stroke program. Here, we discuss those components that need to be further refined in order to improve stroke intervention and outcome.

    2015-01-01

    Background and Purpose It is unknown whether blacks’ elevated risk of dementia is because of racial differences in acute stroke, the impact of stroke on cognitive health, or other factors. We investigated whether racial differences in cognitive decline are explained by differences in the frequency or impact of incident stroke between blacks and whites, controlling for baseline cognition. Methods Among 4908 black and white participants aged ≥65 years free of stroke and cognitive impairment in the nationally representative Health and Retirement Study with linked Medicare data (1998–2010), we examined longitudinal changes in global cognition (modified version of the Telephone Interview for Cognitive Status) by race, before and after adjusting for time-dependent incident stroke followed by a race-by-incident stroke interaction term, using linear mixed-effects models that included fixed effects of participant demographics, clinical factors, and cognition, and random effects for intercept and slope for time. Results We identified 34 of 453 (7.5%) blacks and 300 of 4455 (6.7%) whites with incident stroke over a mean (SD) of 4.1 (1.9) years of follow-up (P=0.53). Blacks had greater cognitive decline than whites (adjusted difference in modified version of the Telephone Interview for Cognitive Status score, 1.47 points; 95% confidence interval, 1.21 to 1.73 points). With further adjustment for cumulative incidence of stroke, the black–white difference in cognitive decline persisted. Incident stroke was associated with a decrease in global cognition (1.21 points; Pstroke on cognition did not statistically differ by race (P=0.52). Conclusions In this population-based cohort of older adults, incident stroke did not explain black–white differences in cognitive decline or impact cognition differently by race. PMID:25999389

    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

    Full Text Available Stroke care presents unique challenges for clinicians, as most strokes occur in the context of other medical diagnoses. An assessment of capacity for implementing “best practice” stroke care found clinicians reporting a strong need for training specific to patient/system complexity and multimorbidity. With mounting patient complexity, there is pressure to implement new models of healthcare delivery for both quality and financial sustainability. Policy makers and administrators are turning to clinical practice guidelines to support decision-making and resource allocation. Stroke rehabilitation programs across Canada are being transformed to better align with the Canadian Stroke Strategy’s Stroke Best Practice Recommendations. The recommendations provide a framework to facilitate the adoption of evidence-based best practices in stroke across the continuum of care. However, given the increasing and emerging complexity of patients with stroke in terms of multimorbidity, the evidence supporting clinical practice guidelines may not align with the current patient population. To evaluate this, electronic databases and gray literature will be searched, including published or unpublished studies of quantitative, qualitative or mixed-methods research designs. Team members will screen the literature and abstract the data. Results will present a numerical account of the amount, type, and distribution of the studies included and a thematic analysis and concept map of the results. This review represents the first attempt to map the available literature on stroke rehabilitation and multimorbidity, and identify gaps in the existing research. The results will be relevant for knowledge users concerned with stroke rehabilitation by expanding the understanding of the current evidence.
