    In the province of Saskatchewan, Canada, stroke is the third leading cause of death as well as the major cause of adult disability. Once a person suffers a stroke or transient ischemic attack (TIA), they are at high risk for having a secondary stroke. Hypertension (elevated blood pressure) is the single most important modifiable risk factor for both first and recurrent stroke, and is thus an important risk factor to be controlled. According to the Canadian Stroke Strategy (CSS) Best Practice Recommendations, blood pressure lowering treatment should be initiated before discharge from hospital for all stroke/TIA patients. The purpose of this study was to examine the quality of medically driven secondary stroke prevention care in Saskatchewan as applied to hypertension control. The objectives of the study were to: (1) develop methodology and calculate a secondary stroke process of care measure using available data in Saskatchewan, based on an appropriate hypertension therapy indicator recommendation from the CSS Performance Measurement Manual; (2) examine variation in secondary stroke prevention hypertensive care among the Saskatchewan Regional Health Authorities; and (3) investigate factors associated with receiving evidence-based hypertensive secondary stroke prevention. This multi-year cross-sectional study was an analysis of deidentified health data derived from linkage of administrative health data. A select indicator from the CSS Performance Measurement Manual that measures adherence to a CSS Best Practice Guidelines concerning use of antihypertensive medications for secondary stroke prevention was calculated. Logistic regression was used to quantify the association of patient demographic and socioeconomic characteristics and geographic location of care with receipt of guideline-recommended hypertensive secondary stroke prevention. The target population was all Saskatchewan residents who were hospitalized in Saskatchewan for a stroke or TIA between April 1, 2001

    Stroke patients are at high risk for recurrence or new occurrence of other cardiovascular events or cardiovascular mortality. It is estimated that a high percentage of non-cardioembolic ischemic stroke can be prevented by a suitable modification of lifestyle (diet and exercise), reducing blood pressure (BP) with antihypertensive medication, platelet aggregation inhibitors, statins and high intake reducing consumption of. Unfortunately the degree of control of the different risk factors in secondary prevention of stroke is low. The clinical practice guidelines show clear recommendations with corresponding levels of evidence, but only if implemented in a general way they will get a better primary and secondary stroke prevention.

    The objective of this study was to evaluate the impact of the prescription of secondary prevention therapies on mortality in Puerto Rican patients hospitalized with a first ischemic stroke. This was a retrospective secondary data analysis of the 2007 and 2009 Puerto Rico Stroke Registry electronic database. Information was obtained from the medical charts of patients discharged with ICD-9 codes 434 and 436 from 20 hospitals located in Puerto Rico. Descriptive analyses were conducted for demographics and comorbidities. Chi2 statistics compared the proportion of patients prescribed secondary prevention therapy and the proportion of patients not prescribed secondary prevention therapy. Lastly, survival rates were calculated from 2007 up to and including December 2010. The mean age of the 3,965 patients was 70 (±14) years. Secondary prevention therapy was prescribed to only 1% of the patients. The most frequent comorbidities were hypertension (85%), diabetes (52%), and hyperlipidemia (25%). The case fatality rate for patients prescribed secondary prevention therapy was 16%, compared to 26% for patients not prescribed secondary prevention therapy (p<0.01). The mean survival for stroke patients prescribed secondary preventions was 450 days (95% CI;182−718), compared to 266 days (95% CI; 244−287) for those not prescribed secondary prevention therapy (p = 0.175). A low percentage of patients with a first ischemic stroke were prescribed secondary prevention therapy. While not statistically significant, survival analysis suggests that secondary prevention therapy decreased mortality in patients with a stroke.

    Full Text Available The review of novel oral anticoagulants (dabigatran, rivaroxaban and apixaban in stroke prevention and also own data of administration of dabigatran in primary and secondary prevention of ischemic stroke in 45 patients with cerebrovascular diseases are presented. Most patients received dabigatran 14 days after the first stroke associated with nonvalvular atrial fibrillation. In other cases dabigatran was used for primary prevention of stroke in patients with chronic forms of cerebrovascular diseases and nonvalvular atrial fibrillation. Dabigatran shows good tolerability and efficacy. Recurrent strokes were diagnosed in 2 patients. The reasons for these events were arterial hypertension in one case and symptomatic atherosclerotic plaque in the other case.

    Full Text Available Vitamin K antagonists, such as warfarin, used in oral anticoagulation therapy currently represent the standard drugs for the primary and secondary prevention of stroke in non-valvular atrial fibrillation (AF, with a relative risk reduction close to 70%. Newer oral anticoagulants, such as direct thrombin inhibitors (i.e., dabigatran and direct factor Xa inhibitors (i.e., apixaban and rivaroxaban have been recently compared with warfarin in large randomized trials for stroke prevention in AF. The new oral anticoagulants showed, compared with warfarin, no statistically significant difference in the rate of stroke or systemic embolism in secondary prevention (patients with previous transient ischemic attack or stroke subgroups. With regard to safety, the risk of intracranial bleeding was reduced with new anticoagulants compared with warfarin. Indirect treatment comparisons of clinical trials on secondary prevention cohorts showed no significant difference in efficacy among apixaban, rivaroxaban, and dabigatran; but dabigatran 110 mg was associated with less intracranial bleedings than rivaroxaban.

    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.

    Worldwide, stroke is the leading cause of mortality and disability, with hypertension being an independent risk factor for a secondary stroke. Acupuncture for the treatment of hypertension gains more attention in alternative and complementary medicine, but the results are inconsistent. Few studies regarding the secondary prevention of stroke by managing hypertension with acupuncture have been carried out as there are some problems regarding the antihypertensive drug status in the secondary prevention of stroke. Still, the potential of acupuncture in regulating the blood pressure for secondary stroke prevention deserves our focus. This review is based on papers recorded in the PubMed, Embase, and Web of Science databases, from their inception until March 28, 2017, and retrieved with the following search terms: hypertension and acupuncture, limited in spontaneously hypertensive rats (SHRs), stress-induced (or cold-induced) hypertensive or pre-hypertensive models. We find that, in these hypertensive animals, acupuncture could mainly influence factors related to the nervous system, oxidative stress, the endocrine system, cardiovascular function, and hemorheology, which are closely associated with the stroke outcome. This trend may give us a hint that acupuncture might well participate in the secondary prevention of stroke through these pathways when used in the management of hypertension. © 2018 S.

    Stroke is the leading cause of disability in the USA and a major cause of mortality worldwide. One out of four strokes is recurrent. Secondary stroke prevention starts with deciphering the most likely stroke mechanism. In general, one of the main goals in stroke reduction is to control vascular risk factors such as hypertension, diabetes, dyslipidemia, and smoking cessation. Changes in lifestyle like a healthy diet and aerobic exercise are also recommended strategies. In the case of cardioembolism due to atrial fibrillation, mechanical valves, or cardiac thrombus, anticoagulation is the mainstay of therapy. The role of anticoagulation is less evident in the case of bioprosthetic valves, patent foramen ovale, and dilated cardiomyopathy with low ejection fraction. Strokes due to larger artery atherosclerosis account for approximately a third of all strokes. In the case of symptomatic extracranial carotid stenosis, surgical intervention as close as possible in time to the index event seems highly beneficial. In the case of intracranial large artery atherosclerosis, the best medical therapy consists of antiplatelets, high-dose statins, aggressive controls of vascular risk factors, and lifestyle modifications, with no role for intracranial arterial stenting or angioplasty. For patients with small artery occlusion (ie, lacunar stroke), the therapy is similar to that used in patients with intracranial large artery atherosclerosis. Despite the constant new evidence on how to best treat patients who have suffered a stroke, the risk of stroke recurrence remains unacceptably high, thus evidencing the need for novel therapies.

    Full Text Available Background: The ischaemic stroke (IS is one of the most frequent cause of death in Germany. Besides of non-drug many drug-based interventions are used in primary or secondary prevention of IS, among them the thrombocyte aggregation inhibitors (TAI. Objectives: The evaluation addresses the questions on medical efficacy and cost-effectiveness of the TAI administration in the prevention of IS as compared to the management of risk factors alone as well as to the use of anticoagulant drugs. Methods: The literature search for articles published after 1997 was conducted in December 2003 in the most important medical and economic databases. The medical analysis was performed on the basis of the most up-to date meta-analyses of randomised controlled trials (RCT as well as of new published RCT. The data from the studies for stroke, bleeding complications as well as for the combined endpoint "severe vascular events" (SVE: death or stroke or myocardial infarction were summarised in meta-analyses.In order to include grey literature contact has been taken up with the pharmaceutical manufacturers of TAI. Results are presented in a descriptive way. Results: The medical analysis included data from 184 RCT (vs. placebo and from 22 RCT (vs. anticoagulant drugs. The absolute reduction of IS (4.8% vs. 6.6%; p<0,00001 and SVE (10.0% vs. 12.4%; p<0,00001 were definitely higher than the absolute increase of bleeding complications (1.6% vs. 0.9%; p<0,00001, but relatively similar to this absolute increase in a subpopulation with a low risk for SVE. With regard to the stroke prevention, evidence of efficacy could be yielded for acetylsalicil acid (ASA, dipyridamole, cilostazol, ridogrel and the combination ASA with dipyridamole. ASA is less effective than anticoagulants in the prevention of ischaemic stroke in atrial fibrillation, however, it causes fewer bleeding complications.Low dosed ASA can be considered cost-effective in secondary prevention of ischemic stroke

    Secondary stroke prevention is an important goal of poststroke patient treatment. Various pharmacologic approaches have been advocated, but the relative efficacy and safety of these regimens has remained the subject of much debate. Recently released data from the European/Australasian Stroke Prevention in Reversible Ischemia Trial (ESPRIT) indicated that combination therapy with aspirin and extended-release dipyridamole was more effective than aspirin monotherapy, and probably more effective than anticoagulants, for the prevention of cerebrovascular events after a stroke or transient ischemic attack. When viewed in light of results of earlier trials, these findings confirmed that combination aspirin plus extended-release dipyridamole therapy improved outcomes in these patients and is a recommended option for poststroke patient treatment.

    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.

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

    Full Text Available Prevention plays a crucial role in counteracting morbidity and mortality related to ischemic stroke. It has been estimated that 50% of stroke are preventable through control of modifiable risk factors and lifestyle changes. Antihypertensive treatment is recommended for both prevention of recurrent stroke and other vascular events. The use of antiplatelets and statins has been shown to reduce the risk of recurrent stroke and other vascular events. Angiotensin-converting enzyme inhibitors (ACEIs and angiotensin II receptor blockers (ARBs are indicated in stroke prevention because they also promote vascular health. Effective secondary-prevention strategies for selected patients include carotid revascularization for high-grade carotid stenosis and vitamin K antagonist treatment for atrial fibrillation. The results of recent clinical trials investigating new anticoagulants (factor Xa inhibitors and direct thrombin inhibitors clearly indicate alternative strategies in stroke prevention for patients with atrial fibrillation. This paper describes the current landscape and developments in stroke prevention with special reference to medical treatment in secondary prevention of ischemic stroke.

    Full Text Available Abstract Background This study aimed to inform the design of a pragmatic trial of stroke prevention in primary care by evaluating data recorded in electronic patient records (EPRs as potential outcome measures. The study also evaluated achievement of recommended standards of care; variation between family practices; and changes in risk factor values from before to after stroke. Methods Data from the UK General Practice Research Database (GPRD were analysed for 22,730 participants with an index first stroke between 2003 and 2006 from 414 family practices. For each subject, the EPR was evaluated for the 12 months before and after stroke. Measures relevant to stroke secondary prevention were analysed including blood pressure (BP, cholesterol, smoking, alcohol use, body mass index (BMI, atrial fibrillation, utilisation of antihypertensive, antiplatelet and cholesterol lowering drugs. Intraclass correlation coefficients (ICC were estimated by family practice. Random effects models were fitted to evaluate changes in risk factor values over time. Results In the 12 months following stroke, BP was recorded for 90%, cholesterol for 70% and body mass index (BMI for 47%. ICCs by family practice ranged from 0.02 for BP and BMI to 0.05 for LDL and HDL cholesterol. For subjects with records available both before and after stroke, the mean reductions from before to after stroke were: mean systolic BP, 6.02 mm Hg; diastolic BP, 2.78 mm Hg; total cholesterol, 0.60 mmol/l; BMI, 0.34 Kg/m2. There was an absolute reduction in smokers of 5% and heavy drinkers of 4%. The proportion of stroke patients within the recommended guidelines varied from less than a third (29% for systolic BP, just over half for BMI (54%, and over 90% (92% on alcohol consumption. Conclusions Electronic patient records have potential for evaluation of outcomes in pragmatic trials of stroke secondary prevention. Stroke prevention interventions in primary care remain suboptimal but important

    Fibrates are a class of drugs characterised by mainly lowering high triglyceride, raising high-density lipoprotein (HDL) cholesterol, and lowering the small dense fraction of low-density lipoprotein (LDL) cholesterol. Their efficacy for secondary prevention of serious vascular events is unclear, and to date no systematic review focusing on secondary prevention has been undertaken. To assess the efficacy and safety of fibrates for the prevention of serious vascular events in people with previous cardiovascular disease (CVD), including coronary heart disease and stroke. We searched the Cochrane Central Register of Controlled Trials (CENTRAL; Issue 9, 2014) on the Cochrane Library, MEDLINE (OVID, 1946 to October week 1 2014), EMBASE (OVID, 1980 to 2014 week 41), the China Biological Medicine Database (CBM) (1978 to 2014), the Chinese National Knowledge Infrastructure (CNKI) (1979 to 2014), Chinese Science and Technique Journals Database (VIP) (1989 to 2014). We also searched other resources, such as ongoing trials registers and databases of conference abstracts, to identify further published, unpublished, and ongoing studies. We included randomised controlled trials (RCTs) in which a fibrate (for example gemfibrozil, fenofibrate) was compared with placebo or no treatment. We excluded RCTs with only laboratory outcomes. We also excluded trials comparing two different fibrates without a placebo or no-treatment control. Two review authors independently selected trials for inclusion, assessed risk of bias, and extracted the data. We contacted authors of trials for missing data. We included 13 trials involving a total of 16,112 participants. Eleven trials recruited participants with history of coronary heart disease, two trials recruited participants with history of stroke, and one trial recruited participants with a mix of people with CVD. We judged overall risk of bias to be moderate. The meta-analysis (including all fibrate trials) showed evidence for a protective

    People with stroke or transient ischaemic attack (TIA) are at increased risk of future stroke and other cardiovascular events. Evidence-based strategies for secondary stroke prevention have been established. However, the implementation of prevention strategies could be improved. To assess the effects of stroke service interventions for implementing secondary stroke prevention strategies on modifiable risk factor control, including patient adherence to prescribed medications, and the occurrence of secondary cardiovascular events. We searched the Cochrane Stroke Group Trials Register (April 2013), the Cochrane Effective Practice and Organisation of Care Group Trials Register (April 2013), CENTRAL (The Cochrane Library 2013, issue 3), MEDLINE (1950 to April 2013), EMBASE (1981 to April 2013) and 10 additional databases. We located further studies by searching reference lists of articles and contacting authors of included studies. We included randomised controlled trials (RCTs) that evaluated the effects of organisational or educational and behavioural interventions (compared with usual care) on modifiable risk factor control for secondary stroke prevention. Two review authors selected studies for inclusion and independently extracted data. One review author assessed the risk of bias for the included studies. We sought missing data from trialists. This review included 26 studies involving 8021 participants. Overall the studies were of reasonable quality, but one study was considered at high risk of bias. Fifteen studies evaluated predominantly organisational interventions and 11 studies evaluated educational and behavioural interventions for patients. Results were pooled where appropriate, although some clinical and methodological heterogeneity was present. The estimated effects of organisational interventions were compatible with improvements and no differences in the modifiable risk factors mean systolic blood pressure (mean difference (MD) -2.57 mmHg; 95% confidence

    Current recommendations do not specifically address the optimal blood pressure (BP) reduction for secondary stroke prevention in patients with previous cerebrovascular events. We conducted a systematic review and metaregression analysis on the association of BP reduction with recurrent stroke and cardiovascular events using data from randomized controlled clinical trials of secondary stroke prevention. For all reported events during each eligible study period, we calculated the corresponding risk ratios to express the comparison of event occurrence risk between patients randomized to antihypertensive treatment and those randomized to placebo. On the basis of the reported BP values, we performed univariate metaregression analyses according to the achieved BP values under the random-effects model (Method of Moments) for those adverse events reported in ≥10 total subgroups of included randomized controlled clinical trials. In pairwise meta-analyses, antihypertensive treatment lowered the risk for recurrent stroke (risk ratio, 0.73; 95% confidence interval, 0.62-0.87; Psecondary stroke prevention. © 2016 American Heart Association, Inc.

    Medications are highly effective at reducing risk of recurrent stroke, but success is influenced by adherence to treatment. Among survivors of stroke and transient ischaemic attack (TIA), adherence to medication is known to be suboptimal. To identify and report barriers to medication adherence for the secondary prevention of stroke/TIA. A qualitative interview study was conducted within general practice surgeries in the East of England, UK. Patients were approached by letter and invited to take part in a qualitative research study. Semi-structured interviews were undertaken with survivors of stroke, caregivers, and GPs to explore their perspectives and views around secondary prevention and perceived barriers to medication adherence. Key themes were identified using a grounded theory approach. Verbatim quotes describing the themes are presented here. In total, 28 survivors of stroke, including 14 accompanying caregivers and five GPs, were interviewed. Two key themes were identified. Patient level barriers included ability to self-care, the importance people attach to a stroke event, and knowledge of stroke and medication. Medication level barriers included beliefs about medication and beliefs about how pills work, medication routines, changing medications, and regimen complexity and burden of treatment. Patients who have had a stroke are faced with multiple barriers to taking secondary prevention medications in UK general practice. This research suggests that a collaborative approach between caregivers, survivors, and healthcare professionals is needed to address these barriers and facilitate medication-taking behaviour. © British Journal of General Practice 2016.

    Full Text Available With majority of ischemic strokes attributable to atherothrombosis and many being predictable after transient ischemic attacks (TIA, the role of early secondary prevention with antiplatelet agents is under renewed investigation. Prior major clinical trials of various secondary stroke prevention regimens pointed to a greater efficacy of dual antiplatelet agents if initiated early from symptom onset. This paper examines data and rationale behind dual antiplatelet regimens across the completed clinical trials. The safety of dual antiplatelets approach is of concern, but it could be outweighed, at least in early management, by a greater reduction in recurrence of ischemic events since this risk is “front loaded” after minor stroke or TIA. Aspirin monotherapy, though considered standard of care, is compared to aspirin-extended release dipiridamole and its combination with clopidogrel in early-phase completed and efficacy-phase ongoing clinical trials.

    BACKGROUND: In patients with ischemic stroke of non-cardioembolic origin, acetylsalicylic acid, clopidogrel, or a combination of acetylsalicylic acid and dipyridamole are recommended for the prevention of a recurrent stroke. The purpose of this study was to examine the risk of bleeding or recurrent...... stroke associated with these three treatments.

    Full Text Available Effective methods of secondary prevention after stroke or TIA are available but adherence to recommended evidence-based treatments is often poor. The study aimed to determine the quality of secondary prevention in usual care and to develop a stepwise modeled support program.Two consecutive cohorts of patients with acute minor stroke or TIA undergoing usual outpatient care versus a secondary prevention program were compared. Risk factor control and medication adherence were assessed in 6-month follow-ups (6M-FU. Usual care consisted of detailed information concerning vascular risk factor targets given at discharge and regular outpatient care by primary care physicians. The stepwise modeled support program additionally employed up to four outpatient appointments. A combination of educational and behavioral strategies was employed.168 patients in the observational cohort who stated their openness to participate in a prevention program (mean age 64.7 y, admission blood pressure (BP: 155/84 mmHg and 173 patients participating in the support program (mean age 67.6 y, BP: 161/84 mmHg were assessed at 6 months. Proportions of patients with BP according to guidelines were 50% in usual-care and 77% in the support program (p<0.01. LDL<100 mg/dl was measured in 62 versus 71% (p = 0.12. Proportions of patients who stopped smoking were 50 versus 79% (p<0.01. 72 versus 89% of patients with atrial fibrillation were on oral anticoagulation (p = 0.09.Risk factor control remains unsatisfactory in usual care. Targets of secondary prevention were met more often within the supported cohort. Effects on (cerebro-vascular recurrence rates are going to be assessed in a multicenter randomized trial.

    In most Asian countries, stroke is one of the major causes of mortality. A stroke event is life-changing for stroke survivors, which results in either mortality or disability. Therefore, this study comprehensively focuses on prevalence, risk factors, and secondary prevention for stroke recurrence identified in South, East, and Southeast Asian countries. This scoping review uses the methodological framework of Arksey and O'Malley. A comprehensive search of academic journals (English) on this topic published from 2007 to 2017 was conducted. A total of 22 studies were selected from 585 studies screened from the electronic databases. First-year stroke recurrence rates are in the range of 2.2% to 25.4%. Besides that, modifiable risk factors are significantly associated with pathophysiological factors (hypertension, ankle-brachial pressure index, atherogenic dyslipidaemia, diabetes mellitus, metabolic syndrome, and atrial fibrillation) and lifestyle factors (obesity, smoking, physical inactivity, and high salt intake). Furthermore, age, previous history of cerebrovascular events, and stroke subtype are also significant influence risk factors for recurrence. A strategic secondary prevention method for recurrent stroke is health education along with managing risk factors through a combination of appropriate lifestyle intervention and pharmacological therapy. To prevent recurrent stroke, health intervention should be geared towards changing lifestyle to embody a healthier approach to life. This is of great importance to public health and stroke survivors' quality of life.

    Full Text Available Background and Purpose: Patients who experience a stroke or transient ischemic attack (TIA are known to be at high risk of subsequent vascular events, underscoring the need for secondary preventive intervention. However, previous studies have indicated insufficiency in the implementation of secondary prevention, emphasizing the need to develop effective methods of follow-up. In the present study, we examined the potential of implementing a telephone-based, nurse-led, secondary preventive follow-up in stroke and TIA patients on a population level by analyzing the participation rate, reasons for nonparticipation, and one-year mortality. Methods: Between January 1, 2010 and December 31, 2011, all patients admitted to Östersund hospital, Sweden, and diagnosed with either stroke or TIA were considered for inclusion into the secondary preventive follow-up. Baseline data were collected at the hospital, and reasons for nonparticipation were documented. Multivariate logistic regression was performed to identify predictors of the patient decision not to participate and to explore independent associations between baseline characteristics and exclusion. A one-year follow-up of mortality was also performed; the survival functions of the three groups (included, excluded, declining participation was calculated using the Kaplan-Meier estimator. Results: From a total of 810 identified patients, 430 (53.1% were included in the secondary preventive follow-up, 289 (35.7% were excluded mainly due to physical or cognitive disability, and 91 (11.2% declined participation. Age ≥85 years, ischemic and hemorrhagic stroke, modified Rankin scale score >3, body mass index ≥25, congestive heart failure, and lower education level were independently associated with exclusion, whereas lower education level was the only factor independently associated with the patient decision not to participate. Exclusion was associated with a more than 12 times higher risk of mortality

    Strokes are often preceded by a transient ischaemic attack (TIA) or 'minor' stroke. The immediate period after a TIA/minor stroke is a crucial time to initiate secondary prevention. However, the optimal approach to prevention, including non-pharmacological measures, after TIA is not clear. To systematically review evidence about the effectiveness of delivering secondary prevention, with lifestyle interventions, in comprehensive rehabilitation programmes, initiated within 90 days of a TIA/minor stroke. Also, to categorise the specific behaviour change techniques used. The review identified randomised controlled trials by searching the Cochrane Library, Ovid MEDLINE, Ovid EMBASE, Web of Science, EBSCO CINAHL and Ovid PsycINFO. Two review authors independently screened titles and abstracts for eligibility (programmes initiated within 90 days of event; outcomes reported for TIA/minor stroke) and extracted relevant data from appraised studies; a meta-analysis was used to synthesise the results. A total of 31 potentially eligible papers were identified and four studies, comprising 774 patients post-TIA or minor stroke, met the inclusion criteria; two had poor methodological quality. Individual studies reported increased aerobic capacity but meta-analysis found no significant change in resting and peak systolic blood pressure, resting heart rate, aerobic capacity, falls, or mortality. The main behaviour change techniques were goal setting and instructions about how to perform given behaviours. There is limited evidence of the effectiveness of early post-TIA rehabilitation programmes with preventive lifestyle interventions. Further robust randomised controlled trials of comprehensive rehabilitation programmes that promote secondary prevention and lifestyle modification immediately after a TIA are needed. © British Journal of General Practice 2017.

    The aftermath of stroke leaves many consequences including cognitive deficits and falls due to imbalance. Stroke survivors and families struggle to navigate the complex healthcare system with little assistance posthospital discharge, often leading to early hospital readmission and worse stroke outcomes. Telemedicine Guided Education on Secondary Stroke and Fall Prevention Following Inpatient Rehabilitation feasibility study examines whether stroke survivors and their caregivers find value in telerehabilitation (TR) home visits that provide individualised care and education by a multidisciplinary team after discharge from inpatient rehabilitation. A prospective, single arm, pilot study is designed to evaluate the feasibility of weekly TR home visits initiated postdischarge from inpatient rehabilitation. Newly diagnosed patients with stroke are recruited from a Houston-based comprehensive stroke centre inpatient rehabilitation unit, loaned an iPad with data plan and trained to use information technology security-approved videoconferencing application. After hospital discharge, six weekly TR home visits are led by rotating specialists (pharmacist, physical/occupational therapist, speech therapist, rehabilitation physician, social worker, geriatrician specialised in fracture prevention) followed by satisfaction survey on week 7. Specialists visually assess patients in real time, educate them on secondary stroke and fall prevention and suggest ways to improve function including direct medical interventions when indicated. Primary outcomes are proportion of eligible patients consenting to the study, participation rate in all six TR home visits and satisfaction score. The study started 31 December 2015 with plan to enrol up to 50 patients over 24 months. Feasibility study results will inform us as to whether a randomised controlled trial is warranted to determine efficacy of TR home visit intervention in improving stroke outcomes.

Health primary care centres in a metropolitan area (944,280 inhabitants). Patients aged 18years and over with ischemic brain disease diagnosis prior to 6months before the study. Clinical history records of demographic variables, risk factors and cardiovascular comorbidity, drugs, blood pressure values (BP), LDL-cholesterol and medical visits by doctor and nurses after the event. Good adherence was considered when BP <140/90 mmHg, LDL-cholesterol <100 mg/dL, smoking abstention and preventive drugs prescription (anti-platelet/anticoagulants, statins and angiotensin-converting-enzyme inhibitors/angiotensin-receptor-antagonists or diuretics) during the last 18months. A total of 21,976 patients, mean age 73.12 years (SD: 12.13), 48% women, 72.7% with stroke. Co-morbidity: hypertension 70.8%, dyslipidemia 55.1%, DM 30.9%, atrial fibrillation 14.1%, ischemic heart disease 13.5%, chronic renal failure 12.5%, heart failure 8.8%, peripheral arterial disease 6.2%, dementia 7.8%. No record was found for smoking in 3.7%, for BP in 3.5% and for LDL in 6.5%. Optimal control: abstention smoking in 3.7%, BP <140/90 in 65.7% and LDL <100 mg/dL in 41.0%. 86.2% anti-platelet/anticoagulants, 61.3% statins and 61.8% angiotensin-converting-enzyme inhibitors, angiotensin-receptor-antagonists or diuretic. Registration and risk factors control was higher in 66-79years aged and lower in 18-40years aged. The implementation of clinical guidelines recommendations for stroke prevention in primary care must be improved, especially among younger population. Organizational changes and more active involvement by professionals and strategies against therapeutic inertia must be taken. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

    Background Sickle cell disease is one of the commonest severe monogenic disorders in the world, due to the inheritance of two abnormal haemoglobin (beta globin) genes. Sickle cell disease can cause severe pain, significant end-organ damage, pulmonary complications, and premature death. Stroke affects around 10% of children with sickle cell anaemia (HbSS). Chronic blood transfusions may reduce the risk of vaso-occlusion and stroke by diluting the proportion of sickled cells in the circulation. This is an update of a Cochrane Review first published in 2002, and last updated in 2013. Objectives To assess risks and benefits of chronic blood transfusion regimens in people with sickle cell disease for primary and secondary stroke prevention (excluding silent cerebral infarcts). Search methods We searched for relevant trials in the Cochrane Library, MEDLINE (from 1946), Embase (from 1974), the Transfusion Evidence Library (from 1980), and ongoing trial databases; all searches current to 04 April 2016. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Haemoglobinopathies Trials Register: 25 April 2016. Selection criteria Randomised controlled trials comparing red blood cell transfusions as prophylaxis for stroke in people with sickle cell disease to alternative or standard treatment. There were no restrictions by outcomes examined, language or publication status. Data collection and analysis Two authors independently assessed trial eligibility and the risk of bias and extracted data. Main results We included five trials (660 participants) published between 1998 and 2016. Four of these trials were terminated early. The vast majority of participants had the haemoglobin (Hb)SS form of sickle cell disease. Three trials compared regular red cell transfusions to standard care in primary prevention of stroke: two in children with no previous long-term transfusions; and one in children and adolescents on long-term transfusion.

Vitamin K antagonists (VKA have been the standard of care for long-term OAT for decades, but non-VKA oral anticoagulants (NOAC have recently been approved for this indication, and raised many questions, among them their influence on medication adherence. We assessed adherence to VKA and NOAC in secondary stroke prevention. Methods: All patients treated from October 2011 to September 2012 for ischemic stroke or transient ischemic attack with a subsequent indication for OAT, at three academic hospitals were entered into a prospective registry, and baseline data and antithrombotic treatment at discharge were recorded. At the 1-year follow-up, we assessed the adherence to different OAT strategies and patients’ adherence to their respective OAT. We noted OAT changes, reasons to change treatment, and factors that influence persistence to the prescribed OAT. Results: In patients discharged on OAT, we achieved a fatality corrected response rate of 73.3% (n=209. A total of 92% of these patients received OAT at the 1-year follow-up. We observed good adherence to both VKA and NOAC (VKA, 80.9%; NOAC, 74.8%; P=0.243 with a statistically nonsignificant tendency toward a weaker adherence to dabigatran. Disability at 1-year follow-up was an independent predictor of lower adherence to any OAT after multivariate analysis, whereas the choice of OAT did not have a relevant influence. Conclusion: One-year adherence to OAT after stroke is strong (>90% and patients

    Full Text Available Abstract Background Patients with recent stroke or TIA are at high risk for new vascular events. Several evidence based strategies in secondary prevention of stroke are available but frequently underused. Support programs with multifactorial risk factor modifications after stroke or TIA have not been investigated in large-scale prospective controlled trials so far. INSPiRE-TMS is a prospective, multi-center, randomized open intervention trial for intensified secondary prevention after minor stroke and TIA. Methods/design Patients with acute TIA or minor stroke admitted to the participating stroke centers are screened and recruited during in-hospital stay. Patients are randomised in a 1:1 ratio to intervention (support program and control (usual care arms. Inclusion of 2.082 patients is planned. The support program includes cardiovascular risk factor measurement and feedback, monitoring of medication adherence, coaching in lifestyle modifications, and active involvement of relatives. Standardized motivational interviewing is used to assess and enhance patients’ motivation. Primary objective is a reduction of new major vascular events defined as nonfatal stroke and myocardial infarction or vascular death. Recruitment time is planned for 3.5 years, follow up time is at least 2 years for every patient resulting in a total study time of 5 years (first patient in to last patient out. Discussion Given the high risk for vascular re-events in acute stroke and the available effective strategies in secondary prevention, the INSPIRE-TMS support program has the potential to lead to a relevant reduction of recurrent events and a prolongation of the event-free survival time. The trial will provide the basis for the decision whether an intensified secondary prevention program after stroke should be implemented into regular care. A cost-effectiveness evaluation will be performed. Trial registration clinicaltrials.gov: 01586702

    The aim of the study was to explore community-dwelling stroke patients' perceived barriers to healthy-lifestyle participation for secondary disease prevention, as well as their preferred means for risk-reduction information dissemination and motivators to participation in healthy-lifestyle interventions. Four focus groups (5-6 stroke survivors per group) were defined from community support groups. Key questions addressed barriers to healthy-lifestyle adoption, preferred methods for receiving information and factors that would engage participants in a risk-reduction programme. Groups were audiotaped, transcribed verbatim and analysed for thematic content using a framework approach. Twenty-two participants, 12 men, 10 women, mean age 71.4 (53-87) years, were included in the study. Three overarching themes emerged as barriers to healthy-lifestyle participation: physical, mental and environmental. Exercise participation difficulties spread across all three themes; healthy eating and smoking cessation concentrated in environmental and mental dimensions. Talks (discussions) were noted as participants' preferred method of information provision. Risk-reduction programmes considered attractive were stroke specific, convenient and delivered by healthcare professionals and involved both social and exercise components. Many stroke patients appear unable to adopt healthy-lifestyle changes through advice alone because of physical, mental and environmental barriers. Risk-reduction programmes including interactive education should be specifically tailored to address barriers currently experienced and extend beyond the stroke survivor to others in their environment who influence lifestyle choices.

    2009-01-01

    Full Text Available Approaches to preventing recurrent stroke by antithrombocytic therapy are shown to be as diverse as its causes. The diagnosis of cardioembolic stroke in patients with atrial fibrillation should not limit the choice of an antithrombocytic agent to only oral (indirect anticoagulants (OAC. If OAC cannot be used, antithrombocytic therapy, including combined (clopidogrel + ASA one, may be considered as a reasonable alternative. Approaches to choosing the optimal antithrombocytic drug in noncardioembolic strokes are intricate since atherosclerosis is a systemic vascular disease and the poststroke period is characterized by a higher risk for not only recurrent stroke, but also for coronary catastrophes. It is concluded that an antithrombocytic agent should be chosen, by taking into account the multifocality of atherosclerosis, associated clinical conditions, diabetes mellitus, intravascular interventions and the individual risk of all cardiovascular events.

  20. Diabetes and Stroke Prevention: A Review

    2012-01-01

    Full Text Available Stroke and diabetes mellitus are two separate conditions which share multiple common threads. Both are increasing in prevalence, both are diseases which affect blood vessels, and both are associated with other vascular risk factors, such as hypertension and dyslipidemia. Abnormal glucose regulation, of which diabetes is one manifestation, is seen in up to two-thirds of people suffering from an acute stroke. Surprisingly, aggressive management of glucose after an acute stroke has not been shown to improve outcome or reduce the incidence of further strokes. More encouragingly, active management of other cardiovascular risk factors has been demonstrated to prevent stroke disease and improve outcome following a stroke in the diabetic person. Hypertension should be treated with a target of 140/80 mmHg, as a maximum. The drug of choice would be an ACE inhibitor, although the priority is blood pressure reduction regardless of the medication chosen. Lipids should be treated with a statin whatever the starting cholesterol. Antiplatelet treatment is also essential but there are no specific recommendations for the diabetic person. As these conditions become more prevalent it is imperative that the right treatment is offered for both primary and secondary prevention in diabetic people, in order to prevent disease and minimize disability.

    Full Text Available Abstract Background The purpose of this research is to develop and evaluate methods for conducting pragmatic cluster randomized trials in a primary care electronic database. The proposal describes one application, in a less frequent chronic condition of public health importance, secondary prevention of stroke. A related protocol in antibiotic prescribing was reported previously. Methods/Design The study aims to implement a cluster randomized trial (CRT using the electronic patient records of the General Practice Research Database (GPRD as a sampling frame and data source. The specific objective of the trial is to evaluate the effectiveness of a computer-delivered intervention at enhancing the delivery of stroke secondary prevention in primary care. GPRD family practices will be allocated to the intervention or usual care. The intervention promotes the use of electronic prompts to support adherence with the recommendations of the UK Intercollegiate Stroke Working Party and NICE guidelines for the secondary prevention of stroke in primary care. Primary outcome measure will be the difference in systolic blood pressure between intervention and control trial arms at 12-month follow-up. Secondary outcomes will be differences in serum cholesterol, prescribing of antihypertensive drugs, statins, and antiplatelet therapy. The intervention will continue for 12 months. Information on the utilization of the decision-support tools will also be analyzed. Discussion The CRT will investigate the effectiveness of using a computer-delivered intervention to reduce the risk of stroke recurrence following a first stroke event. The study will provide methodological guidance on the implementation of CRTs in electronic databases in primary care. Trial registration Current Controlled Trials ISRCTN35701810

    To evaluate the safety and efficacy of percutaneous device closure of patent foramen ovale (PFO) for secondary prevention of ischemic stroke BACKGROUND: Stroke remains the leading cause of serious long-term disability in the United States. The effectiveness of a percutaneous PFO closure in the prevention of recurrent cryptogenic strokes has not been established. We performed a literature search using PubMed, EMBASE, Cochrane Central Register of Controlled Trials, Google Scholar, and Internet-based sources from January 2003 to September 2017. Randomized controlled trails (RCTs) comparing percutaneous PFO closure to medical therapy alone. Five RCTs (CLOSURE I, PC Trial, REDUCE, RESPECT, and CLOSE) with 1,829 patients in the device group and 1,611 patients in the medical group met inclusion criteria. The cumulative incidence of recurrent stroke was 2.02% in the PFO closure arm and 4.4% in the medical therapy group (RR 0.42, 95%CI 0.20, 0.91; P = 0.03). There was no difference in the incidence of death [0.7% vs. 0.9%; RR 0.76 (95% CI 0.35, 1.64), P = 0.49] or adverse events during the follow-up period [24.6% vs. 23.7% (RR 1.03; 95% CI 0.91, 1.16), P = 0.65] between the closure and medical therapy groups. Incidence of atrial fibrillation was significantly higher in closure group compared to medical therapy [4% vs. 0.6% (RR 4.73; 95% CI 2.09, 10.70), P = 0.0002]. The comparative effectiveness of PFO closure (compared to medical therapy) was significantly more pronounced in those younger than 45 years, males, larger shunts and disc design platforms (P < 0.05). Based on the results of this analysis of randomized trial data, percutaneous PFO closure appears to be a safe and effective therapeutic option for the secondary prevention of ischemic stroke in patients with PFO and cryptogenic stroke. © 2018 Wiley Periodicals, Inc.

    The aim of this study was to determine the effectiveness of a community-based stroke prevention programme in (1) improving knowledge about stroke; (2) improving self-health-monitoring practice; (3) maintaining behavioural changes when adopting a healthy lifestyle for stroke prevention. People with minor stroke (or transient ischaemic attack) tend to under-estimate the long-term impact of this on their health. The challenge for nurses is to prevent subsequent strokes by finding ways to promote and sustain appropriate behaviours. Educational intervention is of paramount importance in equipping those at risk with relevant knowledge and self-care strategies for secondary stroke prevention. This study adopted a quasi-experimental design. One hundred and ninety subjects were recruited, of whom 147 (77 in the intervention group and 70 in the control group) completed the study. Data were obtained at three time points: baseline (T0); one week after (T1) and three months after (T2) the intervention. The intervention programme consisted of eight weekly two-hour sessions, with the aims of improving the participants' awareness of their own health signals and of actively involving them in self-care management of their own health for secondary stroke prevention. Significant positive changes were found among participants of the intervention group in the knowledge on stroke warning signs (P lifestyle modification of dietary habits (reduction in salted food intake, P = 0.004). No significant improvement was found in walking exercise participation in the intervention group, yet a significant decrease was detected among the control group. This study found a three-month-sustained effect of positive changes in knowledge and skill from participants who undertook a nurse-led community-based stroke prevention programme. Effective educational intervention by professional nurses helped clients integrate their learned knowledge into their real-life practice. This empowering, that is, the

    Stroke is the prime cause of morbidity and mortality in the general population, and hypertension will increase the recurrence and mortality of stroke. We report a protocol of a pragmatic randomized controlled trial (RCT) using blood pressure (BP)-lowering acupuncture add-on treatment to treat patients with hypertension and stroke. This is a large-scale, multicenter, subject-, assessor- and analyst-blinded, pragmatic RCT. A total of 480 patients with hypertension and ischemic stroke will be randomly assigned to two groups: an experimental group and a control group. The experimental group will receive "HuoXueSanFeng" acupuncture combined with one antihypertensive medication in addition to routine ischemic stroke treatment. The control group will only receive one antihypertensive medication and basic treatments for ischemic stroke. HuoXueSanFeng acupuncture will be given for six sessions weekly for the first 6 weeks and three times weekly for the next 6 weeks. A 9-month follow-up will, thereafter, be conducted. Antihypertensive medication will be adjusted based on BP levels. The primary outcome will be the recurrence of stroke. The secondary outcomes including 24-h ambulatory BP, the TCM syndrome score, the Short Form 36-item Health Survey (SF-36), the National Institute of Health Stroke Scale (NIHSS), as well as the Barthel Index (BI) scale will be assessed at baseline, 6 weeks and 12 weeks post initiating treatments; cardiac ultrasound, carotid artery ultrasound, transcranial Doppler, and lower extremity ultrasound will be evaluated at baseline and 12 weeks after treatment. The safety of acupuncture will also be assessed. We aim to determine the clinical effects of controlling BP for secondary prevention of stroke with acupuncture add-on treatment.

    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

    Comprehensive cardiac rehabilitation (CCR), which integrates structured lifestyle interventions and medications, reduces morbidity and mortality among cardiac patients. CCR has not typically been used with cerebrovascular populations, despite important commonalities with heart patients. We tested feasibility and effectiveness of 6-month outpatient CCR for secondary prevention after transient ischemic attack or mild, nondisabling stroke. This article presents risk factors. A future article will discuss psychological outcomes. Consecutive consenting subjects having sustained a transient ischemic attack or mild, nondisabling stroke within the previous 12 months (mean, 11.5 weeks; event-to-CCR entry) with ≥1 vascular risk factor, were recruited from a stroke prevention clinic providing usual care. We measured 6-month CCR outcomes following a prospective cohort design. Of 110 subjects recruited from January 2005 to April 2006, 100 subjects (mean age, 64.9 years; 46 women) entered and 80 subjects completed CCR. We obtained favorable, significant intake-to-exit changes in: aerobic capacity (+31.4%; Pstroke, offering a promising model for vascular protection across chronic disease entities. We know of no similar previous investigation, and are now conducting a randomized trial.

    Full Text Available Stroke secondary prevention in internist practice is discussed in accordance with up to date guidelines. Modern pharmacotherapy includes antiaggregants or anticoagulants, statins, and antihypertensive drugs. The choice of drugs is mostly founded on the rules of evidence based medicine, which allow adjusting individual treatment depending on clinical conditions. The composition of perindopril and indapamide is a preferred nowadays combination of antihypertensive drugs.

    Full Text Available Cardiovascular disease is the leading cause of death and disability, and  contributes substantially to healthcare budgets. The lipid-lowering drugs, 3-hydroxy-3-methylgulutaryl-coenzyme A (HMG-CoA reductase inhibitor or statins, reducing mortality and cardiovascular morbidity in patients with established cardiovascular disease. Statins therefore have a place in the secondary prevention of cardiovascular disease. Recent experimental and clinical studies suggest that statins may exert vascular protective effect beyond cholesterol reduction. The cholesterol-independet or “pleiotropic” effects of statin include the upregulation and activation of endothelial nitric acid synthase (eNOS that can increase nitric oxide (NO production. Augmentation of NO production increases cerebral blood flow, which can lead to neuroprotection during brain ischaemia. By inhibiting mevalonate synthesis, statins prevent the formation of several isoprenoids (including farnesylpyrophosphate and geranylgeranylpyrophosphate. Inhibiting geranylgeranylation of RhoA small G proteins increases the stability of eNOS mRNA through the remodeling of endothelial actin microfilamens. Moreover, statins directly increase eNOS activity within minutes by activating the pathway involving phosphoinositide 3-kinase and protein kinase B. In the secondary prevention of stroke, the use of statins reduces the incidence of either recurrent stroke or other major vascular events and treatment should be initiated soon after the event. The use of statins does not increase hemorrhagic stroke or cancer and may also favor atherosclerotic plaque regression.

    Until recently there was little evidence that statin therapy reduced the risk of stroke recurrence. The SPARCL trial, published in 2006, was the first trial to show the benefits of statin therapy in preventing recurrent stroke. The SPARCL trial showed that treatment with atorvastatin 80mg/day reduced recurrent stroke in patients with a recent stroke or transient ischemic attack (TIA). Several post hoc analyses of different subgroups followed the SPARCL trial. They have not revealed any significant differences when patients were grouped by age, sex or type of stroke. The SPARCL trial has also helped to identify patients who may have a greater benefit from statins: Patients with carotid stenosis, with more intense lipid lowering, and those who achieve optimal levels of LDL-C, HDL-C, triglycerides, and blood pressure. The trial has also helped to identify individuals at high risk of new vascular events. Clearly there is a before and after in stroke prevention since the SPARCL trial was published.

    2017-01-01

    The influence of fibrates on cardiovascular risk has been the focus of several clinical trials. This Cochrane Collaboration Systematic Review evaluated the efficacy of fibrates for secondary prevention of cardiovascular events and stroke, analyzing 13 randomized controlled trials, in a total of 16 112 participants with a history of cardiovascular disease. Fibrates showed a protective effect for the composite outcome of non-fatal stroke, non-fatal myocardial infarction (MI) and vascular death, mainly due to reduction in the risk of non-fatal or fatal MI. Nonetheless, these results largely relied on studies including clofibrate, a drug withdrawn from the market in 2002. No statistically significant differences regarding adverse events were found between fibrates and placebo. Although insufficient to support the routine prescription of fibrates in this setting, this evidence should be taken into account when deciding on lipid-modifying therapy in dyslipidemic patients with a history of cardiovascular disease.

    2007-01-01

    Varicella in childhood is a self-limiting disease, which usually follows a benign course. However, complications, although rare, may have serious consequences. Ischaemic stroke secondary to post varicella angiopathy is a well-described complication and is estimated to account for up to a third of all strokes in infants. We present three previously healthy children who presented to our centre with ischaemic cerebrovascular infarction due to varicella angiopathy. All three children first presented within six weeks after onset of varicella infection and had MRI changes characteristic of ischaemic stroke secondary to post varicella angiopathy. While one child made an excellent recovery being left with only a minor deficit, the remaining two children were left with considerable morbidity severely affecting quality of life. The varicella vaccine has been proven to be well tolerated, safe and effective. We conclude that varicella vaccination should be considered for inclusion in the vaccination schedule to prevent serious complications which while rare may have devastating consequences.

    Full Text Available The morbidity and mortality after stroke — eprosartan compared with nitrendipine for secondary prevention (MOSES trial compared the effects of two antihypertensive agents in secondary prevention of stroke. The hypothesis of the trial was that in hypertensive stroke patients, for the same level of blood pressure (BP control, eprosartan would be more effective than nitrendipine in reducing cerebrovascular and cardiovascular morbidity and mortality.A total of 710 patients were assigned to an eprosartan-based regimen and 695 to a nitrendipine-based regimen.These patients had hypertension requiring treatment and documented cerebral ischaemia or haemorrhage. They were well matched at baseline in general characteristics, BP and concomitant disease. BP was lowered to the same extent in both treatment arms, with a very similar timeframe. A high proportion of patients in both treatment arms achieved target BP.The combined primary endpoint was a composite of total mortality and total number of cardiovascular and cerebrovascular events, including recurrent events.There were 206 endpoints in the eprosartan group and 255 endpoints in the nitrendipine group.This represents a statistically significant 21% risk reduction in favour of eprosartan. Eprosartan also had advantages over nitrendipine in respect of all cerebrovascular events and first cardiovascular events.

    Studies suggest a J-shaped association between blood pressure and cardiovascular events in the setting of intensive systolic blood pressure control; whether there is a similar association with stroke remains less well established. The Secondary Prevention of Small Subcortical Strokes was a randomized trial to evaluate higher (130-149 mm Hg) versus lower (blood pressure targets in participants with recent lacunar infarcts. We evaluated the association of mean achieved blood pressure, 6 months after randomization, and recurrent stroke, major vascular events, and all-cause mortality. After a mean follow up of 3.7 years, there was a J-shaped association between achieved blood pressure and outcomes; the lowest risk was at ≈124 and 67 mm Hg systolic and diastolic blood pressure, respectively. For example, above a systolic blood pressure of 124 mm Hg, 1 standard deviation higher (11.1 mm Hg) was associated with increased mortality (adjusted hazard ratio: 1.9; 95% confidence interval: 1.4, 2.7), whereas below this level, this relationship was inverted (0.29; 0.10, 0.79), Pblood pressure of 67 mm Hg, a 1 standard deviation higher (8.2 mm Hg) was associated with an increased risk of stroke (2.2; 1.4, 3.6), whereas below this level, the association was in the opposite direction (0.34; 0.13, 0.89), P=0.02 for interaction. The lowest risk of all events occurred at a nadir of ≈120 to 128 mm Hg systolic blood pressure and 65 to 70 mm Hg diastolic blood pressure. Future studies should evaluate the impact of excessive blood pressure reduction, especially in older populations with preexisting vascular disease. URL: http://www.clinicaltrials.gov.

    The aim of this study was to evaluate whether the remote introduction of electronic decision support tools into family practices improves risk factor control after first stroke. This study also aimed to develop methods to implement cluster randomized trials in stroke using electronic health records. Family practices were recruited from the UK Clinical Practice Research Datalink and allocated to intervention and control trial arms by minimization. Remotely installed, electronic decision support tools promoted intensified secondary prevention for 12 months with last measure of systolic blood pressure as the primary outcome. Outcome data from electronic health records were analyzed using marginal models. There were 106 Clinical Practice Research Datalink family practices allocated (intervention, 53; control, 53), with 11 391 (control, 5516; intervention, 5875) participants with acute stroke ever diagnosed. Participants at trial practices had similar characteristics as 47,887 patients with stroke at nontrial practices. During the intervention period, blood pressure values were recorded in the electronic health records for 90% and cholesterol values for 84% of participants. After intervention, the latest mean systolic blood pressure was 131.7 (SD, 16.8) mm Hg in the control trial arm and 131.4 (16.7) mm Hg in the intervention trial arm, and adjusted mean difference was -0.56 mm Hg (95% confidence interval, -1.38 to 0.26; P=0.183). The financial cost of the trial was approximately US $22 per participant, or US $2400 per family practice allocated. Large pragmatic intervention studies may be implemented at low cost by using electronic health records. The intervention used in this trial was not found to be effective, and further research is needed to develop more effective intervention strategies. http://www.controlled-trials.com.

    Secondary prevention medications reduce risk of stroke recurrence, yet many people do not receive recommended treatment, nor take medications optimally. Exploring how patients report making use of practitioners' advice on secondary prevention medicines on an online forum and what feedback was received from other participants. Thematic analysis of the archive of Talkstroke (2004-2011), UK. Posts including any secondary prevention medication terms, General Practitioner (GP) and their replies were identified. Fifity participants talked about practitioners' advice on secondary prevention medications in 43 discussion threads. Patients consulted practitioners for reassurance and dealing with side effects. Practitioners' advice varied from altering to maintaining current treatment. Three main themes emerged from the use of practitioners' advice: patients following advice (reassured, happy when side effects made tolerable, or still retaining anxiety about treatment); patients not following advice (admitting adherence on-off or stopping medications as side effects still not tolerable); asking other participants for feedback on advice received. Practitioners' advice was disregarded mainly when related to dealing with statin side effects, after one or two consultations. Themes for feedback involved sharing experience, directing back to practitioners, or to external evidence. Side effects of secondary prevention medications and statins in particular, cause anxiety and resentment in some patients, and their concerns are not always addressed by practitioners. Practitioners could consider more proactive strategies to manage such side effects. Forum feedback was appropriate and supportive of the practitioners' advice received. Our findings from peer-to-peer online conversations confirm and widen previous research. © The Author 2017. Published by Oxford University Press.

    Full Text Available Guidelines recommend implementation of multimodal interventions to help prevent recurrent TIA/stroke. We undertook a systematic review to assess the effectiveness of behavioral secondary prevention interventions.Searches were conducted in 14 databases, including MEDLINE (1980-January 2014. We included randomized controlled trials (RCTs testing multimodal interventions against usual care/modified usual care. All review processes were conducted in accordance with Cochrane guidelines.Twenty-three papers reporting 20 RCTs (6,373 participants of a range of multimodal behavioral interventions were included. Methodological quality was generally low. Meta-analyses were possible for physiological, lifestyle, psychosocial and mortality/recurrence outcomes. Note: all reported confidence intervals are 95%.

    Stroke constitutes a substantial clinical and socio-economic burden. It is currently the third cause of death worldwide and results in mortality or disability in every third patient at the end of the first year following an acute cerebrovascular event. Although in-hospital mortality rates in stroke patients have decreased, prevention and cardiovascular risk control remain critical for improving the prognosis and reducing stroke burden worldwide. The definitions of stroke and transient ischemic attack (TIA) have been recently modified following the findings from neuroimaging and thrombolysis research. Both stroke and TIA are recurrent and preventable disorders. Both patients with stroke and those with TIA require prompt clinical workup, risk assessment, and appropriate management because the risk of recurrence, stroke, and coronary events is significant. The 5 most common cardiovascular risk factors (high blood pressure, smoking, abdominal obesity, diet, and lack of physical activity) are responsible for 80% of the cases. Stroke prevention involves lifestyle modification and specific treatment. Secondary prevention of ischemic stroke involves early treatment (antiplatelets and carotid interventions) and long-term management including lifestyle changes, antihypertensive therapy, antiplatelets, antithrombotic drugs in patients with atrial fibrillation, and the use of statins and other lipid-lowering drugs. Stroke patients are at risk of depression, dementia, epilepsy, and other complications that also require targeted treatment.

    Patent foramen ovale closure represents a potential secondary prevention strategy for cryptogenic stroke, but available trials have varied by size, device studied, and follow-up. We conducted a systematic search of published randomized clinical trials evaluating patent foramen ovale closure versus medical therapy in patients with recent stroke or transient ischemic attack using PubMED, EMBASE, and Cochrane through September 2017. Weighting was by random effects models. Of 480 studies screened, we included 5 randomized clinical trials in the meta-analysis in which 3440 patients were randomized to patent foramen ovale closure (n = 1829) or medical therapy (n = 1611) and followed for an average of 2.0 to 5.9 years. Index stroke/transient ischemic attack occurred within 6 to 9 months of randomization. The primary end point was composite stroke/transient ischemic attack and death (in 3 trials) or stroke alone (in 2 trials). Patent foramen ovale closure reduced the primary end point (0.70 vs 1.48 events per 100 patient-years; risk ratio [RR], 0.52 [0.29-0.91]; I 2  = 55.0%) and stroke/transient ischemic attack (1.04 vs 2.00 events per 100 patient-years; RR, 0.55 [0.37-0.82]; I 2  = 42.2%) with modest heterogeneity compared with medical therapy. Procedural bleeding was not different between study arms (1.8% vs 1.8%; RR, 0.94 [0.49-1.83]; I 2  = 29.2%), but new-onset atrial fibrillation/flutter was increased with patent foramen ovale closure (6.6% vs 0.7%; RR, 4.69 [2.17-10.12]; I 2  = 29.3%). In patients with recent cryptogenic stroke, patent foramen ovale closure reduces recurrent stroke/transient ischemic attack compared with medical therapy, but is associated with a higher risk of new-onset atrial fibrillation/flutter.

    The aim of this study was to examine predictors of mortality in patients 5 years after ischemic stroke, focusing on cognitive impairment, vulnerability, and vascular risk factors assessed at 6 months post stroke. Patients from the Action on Secondary Prevention Interventions and Rehabilitation in Stroke (ASPIRE-S) cohort were followed up 5 years post ischemic stroke. Vascular risk factors, cognitive impairment, and vulnerability were assessed at 6 months post stroke. Cognitive impairment was assessed using a cutoff score lower than 26 on the Montreal Cognitive Assessment (MoCA). Vulnerability was defined as a score of 3 or higher on the Vulnerable Elders Scale (VES). Mortality and date of death were ascertained using hospital records, death notifications, and contact with general practitioners. Predictors of mortality were explored using multivariate Cox proportional hazards models. Adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) are presented. Sixty-three of 256 patients (24.6%) assessed at 6 months post stroke had died within 5 years. Cognitive impairment (HR [95% CI]: 2.19 [1.42-3.39]), vulnerability (HR [95% CI]: 5.23 [2.92-9.36]), atrial fibrillation (AF) (HR [95% CI]: 2.31 [1.80-2.96]), and dyslipidemia (HR [95% CI]: 1.90 [1.10-3.27]) were associated with increased risk of 5-year mortality. Vulnerability, cognitive impairment, AF, and dyslipidemia at 6 months were associated with increased risks of mortality 5 years post ischemic stroke. Identification and management of these risk factors should be emphasized in poststroke care. Copyright © 2018 National Stroke Association. Published by Elsevier Inc. All rights reserved.

    Stroke is a major healthcare problem and is one of the leading causes of death and serious long-term disability. Prevention of stroke is considered an important strategy. Chuanxiong is traditionally used in China in the treatment and prevention of stroke. In recent years, Chinese researchers have developed new patented Chuanxiong preparations. To assess the effects and safety of Chuanxiong preparations in preventing stroke in high-risk adults. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (2008, Issue 1), MEDLINE (1950 to March 2008), EMBASE (1980 to March 2008), AMED (1985 to March 2008), Chinese Biomedical Database (CBM) (1975 to March 2008), China National Knowledge Infrastructure (CNKI) (1994 to March 2008), and the VIP Database (1989 to March 2008). Trials registers were searched for ongoing studies. No language restrictions were applied. Randomised controlled trials (RCTs) studying the effects of Chuanxiong preparations in preventing stroke were included. Three reviewers independently selected studies for inclusion and two reviewers independently extracted data. Authors of identified RCTs were telephoned to confirm the randomisation procedure. Outcomes assessed included: stroke, composite cardiovascular outcomes, changes in cardiovascular and cerebrovascular haemodynamic indices and adverse events. Peto odds ratio (OR) with 95% confidence intervals (CI) were calculated for dichotomous variables and mean differences for continuous outcomes. Three RCTs (5042 participants) were included. One higher quality study (4415 participants) compared Nao-an capsule with aspirin for primary prevention in high-risk stroke populations. Nao-an capsule appeared to reduce the incidence of stroke compared with aspirin (OR 0.56 95% CI 0.33 to 0.96). One study of low methodological quality indicated that a self-prepared Xifenwan tablet reduced the incidence of stroke in people with transient ischaemia attack (TIA) (OR 0.18, 95% CI 0.04 to 0.78).

  5. Antihypertensive treatment and stroke prevention: are angiotensin receptor blockers superior to other antihypertensive agents?

    Stroke remains a common vascular event with high mortality and morbidity. After heart disease, stroke is the second leading cause of death worldwide in adult persons. Silent or subclinical stroke is likely to occur with even greater frequency than clinical stroke and increases the risk of subsequent cerebrovascular events. Hypertension is by far the single most important controllable risk factor for stroke. The relationship between blood pressure (BP) and stroke mortality is strong, linear, and continuous in subjects with levels of BP higher than 115/75 mm Hg. Blood pressure reduction by antihypertensive treatment is clearly efficacious in the prevention of stroke (both primary and secondary). Although meta-analyses suggest that BP reduction, per se, is the most important determinant for stroke risk reduction, the question is if specific classes of antihypertensive drugs offer special protection against stroke is still controversial. Some studies have suggested that angiotensin receptors blockers (ARBs) appear to offer additional protection against stroke. This has been hypothesized in studies in hypertensives, such as LIFE and SCOPE, and especially in the only comparative trial focused on secondary stroke prevention. In the MOSES trial, the comparison of eprosartan versus nitrendipine in patients with a previous stroke resulted, despite a similar BP reduction, in a significant reduction in the primary composite endpoint of total mortality plus cardiovascular and cerebrovascular events, including recurrent events. These results may suggest a blood pressure-independent effect of ARBs, which can be mediated through several mechanisms, including their ability to counteract other markers of target organ damage, but also through a direct neuroprotective effect.

  6. Recent advances in preventing stroke recurrence [version 1; referees: 2 approved

    2017-06-01

    Full Text Available Recent advances in secondary stroke prevention include new evidence in hypertension, nutrition, anticoagulation, antiplatelet therapy, intracranial stenosis, percutaneous closure of patent foramen ovale, and lipid-lowering therapy. Individualized therapy for hypertension based on phenotyping with plasma renin and aldosterone markedly improves blood pressure control in patients with resistant hypertension. A Mediterranean diet can reduce the risk of stroke by nearly half. The diagnosis and treatment of metabolic vitamin B12 deficiency, and B vitamins to lower homocysteine, can reduce the risk of stroke by approximately 30%. There are problems with clopidogrel that can be overcome by using ticagrelor, and new anticoagulant drugs markedly improve anticoagulation for stroke prevention, particularly in atrial fibrillation. There are pharmacokinetic problems with dabigatran that deserve attention. Intensive medical therapy is better than stenting for intracranial stenosis, and new therapies directed at proprotein convertase subtilisin–kexin type 9 (PCSK9 will revolutionize lipid-lowering therapy. In the past, it was estimated that rational therapy could reduce recurrent stroke by about 80%. With recent advances, we should be able to do even better.

  8. Did the introduction of a prospective payment system for nursing home stays reduce the likelihood of pharmacological management of secondary ischaemic stroke?

    2006-01-01

    Since 1998, a prospective payment system (PPS) for Medicare services provided by nursing homes in the US has been in operation. Concerns have been expressed that the PPS may affect the quality of care delivered to residents. This study evaluates the impact of the PPS on pharmacological secondary ischaemic stroke prevention in nursing homes. The nationally mandated Minimum Data Set and Online Survey Certification and Automated Record data system from 1997 and 2000 for four states were used. We conducted a quasi-experimental study comparing the pharmacological treatment rates for secondary stroke prevention in the pre-PPS period (1997) with those in the post-PPS period (2000) in residents who experienced an ischaemic stroke within 6 months (n1997 = 5008; n2000 = 5243) of living in nursing facilities (n1997 = 1226; n2000 = 1092) in Kansas, Maine, Mississippi or Ohio. The sample was stratified according to recommendations for use of warfarin. Logistic regression models adjusting for clustering effects of residents residing in homes using generalised estimating equations provided estimates of the PPS effect on use of antiplatelets and the use of warfarin. The unadjusted proportion of use of pharmacological agents for the secondary prevention of stroke was similar for warfarin in both time periods and increased for antiplatelets in 2000. Relative to the pre-PPS era, the likelihood of use of antiplatelets increased in the post-PPS era (adjusted odds ratio 1.26; 95% CI 1.15, 1.38); there was no effect on the use of warfarin. Although the lack of a PPS effect on pharmacological management of secondary ischaemic stroke is encouraging, there is still room for improvement in overall stroke management.

    Full Text Available  Ischemic stroke secondary to aortic dissection is not uncommon. We present a patient with left hemiplegia secondary to Stanford type A aortic dissection extending to the supra-aortic vessels, which was precipitated by rifle butt recoil chest injury. The diagnosis of aortic dissection was delayed due to various factors. Finally, the patient underwent successful Bentall procedure with complete resolution of symptoms. This case emphasizes the need for caution in the use of firearms for recreation and to take precautions in preventing such incidents. In addition, this case illustrates the need for prompt cardiovascular physical examination in patients presenting with stroke.

    Full Text Available Stroke disease in Ghana has been of increasing concern since the mid to late 20th century, in association with the increasing westernisation of diet and lifestyle [1]. Two thirds of world-wide mortality cases from stroke occur in sub-Saharan Africa [2], and in the Ghanaian capital city region of Accra, stroke is now attributed as the second largest cause of death [1]. The burden of stroke in sub-Saharan Africa is significant [3]. Experts recommend a three-prong approach to dealing with the burden of non-communicable disease (NCD: epidemiological surveillance; primary prevention (preventing disease in healthy populations; and secondary prevention (preventing complications and improving quality of life in affected communities [4]. This paper outlines the development of a specialist stroke service in Accra, Ghana. This work therefore broadly relates to the secondary prevention aspect, achieved through the development of a dedicated and specialised stroke service. Whilst this project took place in Ghana, the learning could be applied to the development of a stroke service in any resource poor setting, such as South Sudan. Indeed, because the focus is on establishing the fundamentals of organised stroke care, the principles are also entirely relevant to more developed health care systems.

    2014-01-01

    Perceptions that stress causes and stress-reduction controls hypertension have been associated with poorer blood pressure (BP) control in hypertension populations. The current study investigated these "stress-model perceptions" in stroke survivors regarding prevention of recurrent stroke and the influence of these perceptions on patients' stroke risk factor control. Stroke and transient ischemic attack survivors (N=600) participated in an in-person interview in which they were asked about their beliefs regarding control of future stroke; BP and cholesterol were measured directly after the interview. Counter to expectations, patients who endorsed a "stress-model" but not a "medication-model" of stroke prevention were in better control of their stroke risk factors (BP and cholesterol) than those who endorsed a medication-model but not a stress-model of stroke prevention (OR for poor control=.54, Wald statistic=6.07, p=.01). This result was not explained by between group differences in patients' reported medication adherence. The results have implications for theory and practice, regarding the role of stress belief models and acute cardiac events, compared to chronic hypertension.

  1. Primary prevention of cardiovascular disease through population-wide motivational strategies: insights from using smartphones in stroke prevention

    Feigin, Valery L; Norrving, Bo; Mensah, George A

    2017-01-01

    The fast increasing stroke burden across all countries of the world suggests that currently used primary stroke and cardiovascular disease (CVD) prevention strategies are not sufficiently effective. In this article, we overview the gaps in, and pros and cons of, population-wide and high-risk prevention strategies. We suggest that motivating and empowering people to reduce their risk of having a stroke/CVD by using increasingly used smartphone technologies would bridge the gap in the population-wide and high-risk prevention strategies and reduce stroke/CVD burden worldwide. We emphasise that for primary stroke prevention to be effective, the focus should be shifted from high-risk prevention to prevention at any level of CVD risk, with the focus on behavioural risk factors. Such a motivational population-wide strategy could open a new page in primary prevention of not only stroke/CVD but also other non-communicable disorders worldwide. PMID:28589034

    Full Text Available Background: Stroke is the third common cause of disability and death. Diagnosis of stroke is based on its clinical manifestations and/or observation of infarct in the neuroimaging. Standard battery of diagnostic investigations and classification criteria is required for detection of stroke etiology. Materials and Method: This review article deals with the diagnosis and management of brain infarction particularly in our country and is provided for non-neurologists. Using online scientific search engines and in some parts referring to laboratory archives constituted base of this review article.Results: Acute stroke management is almost similar in its various etiologies. Neuroprotective drugs have little value in acute stroke management. At present time, a few Iranian medical centers have infrastructure of thrombolysis therapy. Prevention of stroke is based on the detection and control of its risk factors. Aspirin, 80 mg per day is the most common drug for stroke prevention. Co-administration of aspirin 80 mg/d and Dipyridamole 200-400 mg/d increases the preventive effects of aspirin. Clopidogrel 75 mg/d is the stroke preventive drug of choice in patients with peptic ulcer and coronary artery disease. Co-administration of aspirin and clopidogrel is more effective in stroke prevention but has more hemorrhagic complications. Using warfarin for stroke prevention is suggested only in patients who have facilities for repetitive coagulation tests. Carotid endarterectomy is indicated in symptomatic patients with more than 70% stenosis of extracranial internal carotid artery, if performed only by vascular surgeons experienced in carotid surgery.Conclusion: Many stroke patients are managed by general practitioners and non-neurologists, e.g. internists, cardiologists and neurosurgeons. This review article provides continuous medical education according to Iranian medical curriculum

  5. Atrial fibrillation and stroke prevention practices in patients with candidacy for anticoagulation therapy

    International Nuclear Information System (INIS)

    Ullah, I.; Ahmad, S.; Hayat, Y.

    2015-01-01

    Background: Stroke secondary to Atrial Fibrillation is usually due to thrombi formed in the left atrium and left atrial appendage embolizing to cause ischemic stroke. Therefore, in patients with Atrial Fibrillation, antithrombotic therapy is recommended to prevent stroke. Vitamin K antagonist therapy is most widely used antithrombotic therapy for patients with valvular and non valvular AF. Aspirin is recommended only in low risk patients. This study was conducted to determine the stroke prevention practices in local patients with atrial fibrillation who were candidates for anticoagulation therapy. Method: This was descriptive cross sectional study conducted at Cardiovascular Department Lady Reading Hospital Peshawar and Cardiology Department Hayatabad Medical Complex Peshawar. Sampling technique was non probability consecutive. Patients visiting OPD of respective hospitals with EKG evidence of AF and having CHADES VASC score 2 or more or having mitral stenosis and AF were included in the study. Patients with additional indications for anticoagulation were excluded from the study. Results: A total of 205 patients with atrial fibrillation were studied. Mean age was 60.7±14.7 years. Male were 55.6 percentage (n=114) while 44.4 percentage (n=91) were female. Of these 149 (72.7 percentage) were candidates for anticoagulation based on CHA2DS2 VASc score of 2 and more or mitral stenosis with AF. Only 27.5 percentage (n=41) patients were adequately treated with anticoagulant therapy using VKA or novel oral anticoagulant drugs. Majority of them were getting dual antiplatelet therapy (DAPT). Conclusion: Most patients with AF and high risk characteristics for thromboembolism are not receiving proper stroke prevention therapies. (author)

    Full Text Available Abstract Background Fibrates has been extensively used to improve plasma lipid levels and prevent adverse cardiovascular outcomes. However, the effect of fibrates on stroke is unclear at the present time. We therefore carried out a comprehensive systematic review and meta-analysis to evaluate the effects of fibrates on stroke. Methods We systematically searched Medline, Embase, the Cochrane Central Register of Controlled Trials, reference lists of articles, and proceedings of major meetings to identify studies for our analysis. We included randomized placebo controlled trials which reported the effects of fibrates on stroke. Relative risk (RR was used to measure the effect of fibrates on the risk of stroke under random effect model. The analysis was further stratified by factors that could affect the treatment effects. Results Overall, fibrate therapy was not associated with a significant reduction on the risk of stroke (RR, 1.02, 95% CI, 0.90 to 1.16, P = 0.78. In the subgroup analyses, we observed that gemfibrozil therapy showed a beneficial effect on stroke (RR, 0.72, 95% CI, 0.53 to 0.98, P = 0.04. Similarly, fibrate therapy comparing to placebo had no effect on the incidence of fatal stroke. Subgroup analysis suggested that fibrate therapy showed an effect on fatal stroke when the Jadad score more than 3 (RR, 0.41, 95% CI, 0.17 to 1.00, P = 0.049. Furthermore, a sensitivity analysis indicated that fibrate therapy may play a role in fatal stroke (RR, 0.49, 95% CI, 0.26 to 0.93, P = 0.03 for patients with previous diabetes, cardiovascular disease or stroke. Conclusions Our study indicated that fibrate therapy might play an important role in reducing the risk of fatal stroke in patients with previous diabetes, cardiovascular disease or stroke. However, it did not have an effect on the incidence of stroke.

    2013-10-01

    Despite the benefits in reducing the risk of stroke, primary prevention is not well translated into practice. We sought to evaluate patient compliance with guidelines and the cost of primary stroke prevention in southwest China. We consecutively enrolled 305 patients with headaches and/or dizziness who were at high risk of stroke from our hospital. We retrospectively obtained their information, including the extent of their knowledge of stroke risk factors, adherence to guidelines, medications taken, and costs of primary prevention for stroke within the past year. Only 45.9% of patients had any knowledge of primary prevention, and only 17.0% had completely followed guidelines. Moreover, 79.0% of the patients were using medications, but only 39.3% took their medication as recommended. In patients who took medication, 89.6% were prescribed by physicians. The annual costs of primary prevention were estimated to be US$517.8 per capita, which included direct medical costs (US$435.4), direct non-medical costs (US$18.1), and indirect costs (US$64.3). Costs in the hypertension group were less than those reported by a similar international study. Although our population sample may not be representative of the population at high risk of stroke in China, it is appropriate for the evaluation of our primary prevention system. Primary prevention for stroke in southwest China is very challenging, with few medical resource investments. There is a current urgency to improve patient knowledge of primary prevention, which would bridge the gaps between guidelines and practice and increase medical resource investments.

    Full Text Available Abstract Background Ischemic stroke by septic embolism occurs primarily in the context of infective endocarditis or in patients with a right-to-left shunt and formation of a secondary cerebral abscess is a rare event. Erosion of pulmonary veins by a pulmonary abscess can lead to transcardiac septic embolism but to our knowledge no case of septic embolic ischemic stroke from a pulmonary abscess with secondary transformation into a brain abscess has been reported to date. Case presentation We report the case of a patient with a pulmonary abscess causing a septic embolic cerebral infarction which then transformed into a cerebral abscess. After antibiotic therapy and drainage of the abscess the patient could be rehabilitated and presented an impressive improvement of symptoms. Conclusion Septic embolism should be considered as cause of ischemic stroke in patients with pulmonary abscess and can be followed by formation of a secondary cerebral abscess. Early antibiotic treatment and repeated cranial CT-scans for detection of a secondary abscess should be performed.

    Full Text Available Stroke is the most common complication of atrial fibrillation (AF. Guidelines recommend anticoagulant treatment in patients with CHA2DS2VASc scores of >2. Registry data suggests that almost half of patients who should be on therapeutic anticoagulation for stroke prevention in AF (SPAF are not. Warfarin and more recently developed agents, the “novel anticoagulants” (NOACs reduce the risk of embolic strokes. In addition, the NOACs also reduce intracranial hemorrhage (ICH by over 50% compared to warfarin. Anticoagulation and bridging strategies involving cardioversion, catheter ablation, and invasive/surgical procedures are reviewed. The development of reversal agents for NOACs and the introduction of left atrial appendage occluding devices will evolve the use of newer strategies for preventing stroke in high risk AF patients.

    Full Text Available Despite vitamin K antagonists (VKAs are considered the first choice treatment for stroke prevention in atrial fibrillation (AF, literature shows their underuse in this context. Since data about VKAs use prior and after acute stroke lack, the aim of this study was to focus on management of anticoagulation with VKAs in this context. Data were retrieved from Tuscan FADOI Stroke Registry, an online data bank aimed to report on characteristics of stroke patients consecutively admitted in Internal Medicine wards in 2010 and 2011. In this period 819 patients with mean age 76.5±12.3 years were enrolled. Data on etiology were available for 715 of them (88.1%, 87% being ischemic and 13% hemorrhagic strokes. AF was present in 238 patients (33%, 165 (69.3% having a known AF before hospitalization, whereas 73 patients (31.7% received a new diagnosis of AF. A percentage of 89% of strokes in patients with known AF were ischemic and 11% hemorrhagic. A percentage of 86.7% of patients with known AF had a CHADS2 ≥2, but only 28.3% were on VKAs before hospitalization. A percentage of 78.8% of patients treated with VKAs before stroke had an international normalized ratio (INR ≤2.0; 68.7% of patients with VKAs-related hemorrhagic strokes had INR ≤3.0. Combined endpoint mortality or severe disability in patients with ischemic stroke associated with AF was present in 47%, while it was present in 19.30% and 19.20% of atherothrombotic and lacunar strokes, respectively. At hospital discharge, VKAs were prescribed in 25.9% of AF related ischemic stroke patients. AF related strokes are burdened by severe outcome but VKAs are dramatically underused in patients with AF, even in higher risk patients. Efforts to improve anticoagulation in this stroke subtype are warranted.

    Stroke affects approximately 16.9 million individuals per year worldwide and is the second leading cause of death. Stroke represents a family of related, but distinct subtypes. Classifying stroke subtypes must take into account various aspects of a standardized stroke workup to allow optimization of treatment and prevention strategies. Secondary prevention and pharmacologic treatment is tailored based on stroke mechanism. Additionally prognostication and recurrent risk also depends on stroke etiology. Efficient workup of stroke relies on a thorough history, clinical examination, imaging studies, and putative mechanism of stroke that lead the treating physician to a particular etiological path. Here , we provide the reader with updated definitions of etiologic ischemic stroke types as well as efficient workup strategies.

    Full Text Available The classification of an acute vascular episode, both heart infarct and stroke, as an accident at work poses difficulties not only for post accidental teams, but also to occupational health professionals, experts and judges at labor and social insurance courts. This article presents the case of a 41-year-old office worker, whose job involved client services. While attending a very aggressive customer she developed solid stress that resulted in symptoms of the central nervous system (headache, speech disturbances. During her hospitalisation at the neurological unit ischemic stroke with transient mixed type aphasia was diagnosed. Magnetic resonance imaging (MRI scan of the head revealed subacute ischemia. After an analysis of the accident circumstances, the employer’s post accidental team decided that ischemic stroke had been an accident at work, because it was a sudden incident due to an external cause inducing work-related traumatic stroke. As a primary cause tough stress and emotional strain due to the situation developed while attending the customer were acknowledged. During control medical check up after 5 months the patient was found to be fit for work, so she could return to work. However, it should be noted that such a check up examination of subjects returning to work after stroke must be holistic, including the evaluation of job predispositions and health education aimed at secondary prevention of heart and vascular diseases with special reference to their risk factors.

    There is little control of cardiovascular (CV) risk factors in secondary prevention after an ischaemic stroke, in part due to a lack of adherence to treatment. The CV polypill may contribute to proper treatment adherence, which is necessary for CV disease prevention. This study aimed to establish how and in what cases the CV polypill should be administered. A group of 8 neurologists drafted consensus recommendations using structured brainstorming and based on their experience and a literature review. These recommendations are based on the opinion of the participating experts. The use of the CV polypill is beneficial for patients, healthcare professionals, and the health system. Its use is most appropriate for atherothrombotic stroke, lacunar stroke, stroke associated with cognitive impairment, cryptogenic stroke with CV risk factors, and silent cerebrovascular disease. It is the preferred treatment in cases of suspected poor adherence, polymedicated patients, elderly people, patients with polyvascular disease or severe atherothrombosis, young patients in active work, and patients who express a preference for the CV polypill. Administration options include switching from individual drugs to the CV polypill, starting treatment with the CV polypill in the acute phase in particular cases, use in patients receiving another statin or an angiotensin ii receptor antagonist, or de novo use if there is suspicion of poor adherence. Nevertheless, use of the CV polypill requires follow-up on the achievement of the therapeutic objectives to make dose adjustments. This document is the first to establish recommendations for the use of the CV polypill in cerebrovascular disease, beyond its advantages in terms of treatment adherence.

    Whitford, David L

    2009-01-01

    BACKGROUND: Stroke is a major cause of mortality and morbidity with potential for improved care and prevention through general practice. A national survey was undertaken to determine current resources and needs for optimal stroke prevention and care. METHODS: Postal survey of random sample of general practitioners undertaken (N = 204; 46% response). Topics included practice organisation, primary prevention, acute management, secondary prevention, long-term care and rehabilitation. RESULTS: Service organisation for both primary and secondary prevention was poor. Home management of acute stroke patients was used at some stage by 50% of responders, accounting for 7.3% of all stroke patients. Being in a structured cardiovascular management scheme, a training practice, a larger practice, or a practice employing a practice nurse were associated with structures and processes likely to support stroke prevention and care. CONCLUSION: General practices were not fulfilling their potential to provide stroke prevention and long-term management. Systems of structured stroke management in general practice are essential to comprehensive national programmes of stroke care.

    Despite relatively lower prevalence of atrial fibrillation (AF) in Asians (~1%) than in Caucasians (~2%), Asia has a much higher overall disease burden because of its proportionally larger aged population. For example, on the basis of reported age-adjusted prevalence rates and projected population figures in China, there will be an estimated 5.2 million men and 3.1 million women with AF older than 60 years by year 2050. Stroke is a disabling complication of AF that is of increasing cause for concern in Asians patients. Implementing consensus expert recommendations for managing stroke risk in patients with AF can considerably reduce stroke rates. However, caution is necessary when aligning management of Asian patients with AF to that of their Caucasian counterparts. Current international guidelines and risk stratification tools for AF management are based on findings in predominantly Caucasian populations and may therefore have limited relevance, in certain respects, to Asian patients. Oral anticoagulants play an important role in preventing AF-related stroke. The vitamin K antagonist warfarin is recommended for reducing the risk of stroke and thromboembolism in high-risk patients with nonvalvular AF; however, warfarin interacts with many drugs and food ingredients, which may pose significant challenges in administration and monitoring among Asian patients. Further research is needed to inform specific guidance on the implications of different stroke and bleeding profiles in Asians vs Caucasians. Moreover, there is scope to improve physician perceptions and patient knowledge, as well as considering alternative new oral anticoagulants, for example, direct thrombin inhibitors or factor Xa inhibitors.

    To determine whether a multifactorial falls prevention program reduces falls in people with stroke at risk of recurrent falls and whether this program leads to improvements in gait, balance, strength, and fall-related efficacy. A single blind, multicenter, randomized controlled trial with 12-month follow-up. Participants were recruited after discharge from rehabilitation and followed up in the community. Participants (N=156) were people with stroke at risk of recurrent falls being discharged home from rehabilitation. Tailored multifactorial falls prevention program and usual care (n=71) or control (usual care, n=85). Primary outcomes were rate of falls and proportion of fallers. Secondary outcomes included injurious falls, falls risk, participation, activity, leg strength, gait speed, balance, and falls efficacy. There was no significant difference in fall rate (intervention: 1.89 falls/person-year, control: 1.76 falls/person-year, incidence rate ratio=1.10, P=.74) or the proportion of fallers between the groups (risk ratio=.83, 95% confidence interval=.60-1.14). There was no significant difference in injurious fall rate (intervention: .74 injurious falls/person-year, control: .49 injurious falls/person-year, incidence rate ratio=1.57, P=.25), and there were no significant differences between groups on any other secondary outcome. This multifactorial falls prevention program was not effective in reducing falls in people with stroke who are at risk of falls nor was it more effective than usual care in improving gait, balance, and strength in people with stroke. Further research is required to identify effective interventions for this high-risk group. Copyright © 2012 American Congress of Rehabilitation Medicine. Published by Elsevier Inc.

    Antiplatelet therapy is an important component of our armamentarium for recurrent stroke prevention. Aspirin is a safe and effective antiplatelet drug for recurrent stroke prevention, however, it has been challenged recently by the thienopyridine derivative, clopidogrel, and the combination agent, aspirin plus extended release dipyridamole. In this review, we discuss recent studies of thienopyridine derivatives and aspirin plus extended-release dipyridamole in stroke prevention and evidence-based guidelines for the administration of these agents in practice for recurrent stroke prevention.

    A number of registry studies have reported suboptimal adherence to guidelines for cardiovascular prevention during the first year after acute myocardial infarction (AMI). However, only a few studies have addressed long-term secondary prevention after AMI. This study evaluates prevention guideline adherence and outcome of guideline-directed secondary prevention in patients surviving 2 years after AMI. Patients aged 18-85 years at the time of their index AMI were consecutively identified from hospital discharge records between July 2010 and December 2011 in Gothenburg, Sweden. All patients who agreed to participate in the study (16.2%) were invited for a structured interview, physical examinations and laboratory analysis 2 years after AMI. Guideline-directed secondary preventive goals were defined as optimally controlled blood pressure, serum cholesterol, glucose, regular physical activity, smoking cessation and pharmacological treatment. The mean age of the study cohort (n = 200) at the index AMI was 63.0 ± 9.7 years, 79% were men. Only 3.5% of the cohort achieved all six guideline-directed secondary preventive goals 2 years after infarction. LDL therapy was used by 97% of the patients, beta-blockers by 83.0%, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers by 76.5% and statins by 88.5%. During follow-up, non-fatal adverse cardiovascular events (cardiac hospitalization, recurrent acute coronary syndrome, angina pectoris, new percutaneous coronary intervention, new onset of atrial fibrillation, post-infarct heart failure, pacemaker implantation, stroke/transient ischemic attack (TIA), cardiac surgery and cardiac arrest) occurred in 47% of the cohort and readmission due to cardiac causes in 30%. Our data showed the failure of secondary prevention in our daily clinical practice and high rate of non-fatal adverse cardiovascular events 2 years after AMI.

    Acute ischemic stroke affects over 800,000 US adults annually, with hundreds of thousands more experiencing a transient ischemic attack. Emergent evaluation, prompt acute treatment, and identification of stroke or TIA (transient ischemic attack) etiology for specific secondary prevention are critical for decreasing further morbidity and mortality of cerebrovascular disease. The Biomarkers of Acute Stroke Etiology (BASE) study is a multicenter observational study to identify serum markers defining the etiology of acute ischemic stroke. Observational trial of patients presenting to the hospital within 24 h of stroke onset. Blood samples are collected at arrival, 24, and 48 h later, and RNA gene expression is utilized to identify stroke etiology marker candidates. The BASE study began January 2014. At the time of writing, there are 22 recruiting sites. Enrollment is ongoing, expected to hit 1000 patients by March 2017. The BASE study could potentially aid in focusing the initial diagnostic evaluation to determine stroke etiology, with more rapidly initiated targeted evaluations and secondary prevention strategies.Clinical Trial Registration Clinicaltrials.gov NCT02014896 https://clinicaltrials.gov/ct2/show/NCT02014896?term=biomarkers+of+acute+stroke+etiology&rank=1.

    Full Text Available The rate of cardiogenic embolism among all ischemic strokes is as high as 38%. Cardioembolic strokes are characterized by the higher magnitude of neurological deficit, the high risk of recurrent acute stroke, and a lethal outcome. This review deals with the etiopathogenesis of thrombus formation in the heart chambers, with current criteria for the verification of cardioembolic strokes, with the results of trials of new oral anticoagulants, and latest guidelines for antithrombotic therapy to prevent stroke. Special focus is given to secondary stroke prevention in patients with nonvalvular atrial fibrillation since it is atrial fibrillation that is the most common cause of cardioembolic stroke.

    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

  19. Strokes In Young Adults And Children

    Full Text Available Stroke is in second place on a mortality list in the world. Also, stroke is a leading cause of disability. Approximately 20% of all strokes occur in Children and young adults. The etiology of stroke in Children and young adults is different from that in older patients, and has an influence on diagnostic evaluation and treatment, so knowledge about older patients cannot always be applied to these patients. The list of stroke etiologies among young adults and children is extensive. Ischemic stroke are more frequent than hemorrhagic strokes in both groups. Stroke in young adults had been thought to be associated with   risk factors, including arterial (such as dissection, reversible cerebral vasoconstriction syndrome, inflammatory arteritis ,moyamoya ,migraine - induced stroke, genetic or inherted arteriopathy, premature atherosclerosis cardiac (such as patent foramen ovale, cardiomyopathy , congenital heart disease and   hematologic (such as  deficiencies of protein S,protein C,or antithrombin;factor V lieden mutation . Common risk factors for stroke in children include: Sickle-cell disease, diseases of the arteries, abnormal blood clotting, head or neck trauma. There are no specific recommendations or guidelines for primary or secondary stroke prevention in young adults. Primary prevention focused on identifying and managing known vascular risk factors, such as hypertension, disorders of lipid metabolism, and diabetes, and non-drug strategies and lifestyle changes, including smoking, reducing body weight, increasing regular aerobic physical activity, and adopting a healthy diet with more fruit and vegetables and less salt. For secondary stroke prevention, identification of the etiologic mechanism of the initial stroke and the presence of any additional risk factors is most important. It consists of optimal treatment of vascular risk factors administering antiplatelet or anticoagulant therapy, and if indicated, invasive surgical or

    Stroke is the main cause of disability in high-income countries and ranks second as a cause of death worldwide. Infections occur frequently after stroke and may adversely affect outcome. Preventive antibiotic therapy in the acute phase of stroke may reduce the incidence of infections and improve outcome. In the previous version of this Cochrane Review, published in 2012, we found that antibiotics did reduce the risk of infection but did not reduce the number of dependent or deceased patients. However, included studies were small and heterogeneous. In 2015, two large clinical trials were published, warranting an update of this Review. To assess the effectiveness and safety of preventive antibiotic therapy in people with ischaemic or haemorrhagic stroke. We wished to determine whether preventive antibiotic therapy in people with acute stroke:• reduces the risk of a poor functional outcome (dependency and/or death) at follow-up;• reduces the occurrence of infections in the acute phase of stroke;• reduces the occurrence of elevated body temperature (temperature ≥ 38° C) in the acute phase of stroke;• reduces length of hospital stay; or• leads to an increased rate of serious adverse events, such as anaphylactic shock, skin rash, or colonisation with antibiotic-resistant micro-organisms. We searched the Cochrane Stroke Group Trials Register (25 June 2017); the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 5; 25 June 2017) in the Cochrane Library; MEDLINE Ovid (1950 to 11 May 2017), and Embase Ovid (1980 to 11 May 2017). In an effort to identify further published, unpublished, and ongoing trials, we searched trials and research registers, scanned reference lists, and contacted trial authors, colleagues, and researchers in the field.

    Background Physical inactivity is a major risk factor for stroke. Korean immigrant seniors are one of the most sedentary ethnic groups in the United States. Objectives To gain better understanding of (i) Beliefs and knowledge about stroke; (ii) Attitudes about walking for stroke prevention; and (iii) Barriers and facilitators to walking among Korean seniors for the cultural tailoring of a stroke prevention walking program. Design An explorative study using focus group data. Twenty-nine Korean immigrant seniors (64–90 years of age) who had been told by a doctor at least once that their blood pressure was elevated participated in 3 focus groups. Each focus group consisted of 8–11 participants. Methods Focus group audio tapes were transcribed and analyzed using standard content analysis methods. Results Participants identified physical and psychological imbalances (e.g., too much work and stress) as the primary causes of stroke. Restoring ‘balance’ was identified as a powerful means of stroke prevention. A subset of participants expressed that prevention may be beyond human control. Overall, participants acknowledged the importance of walking for stroke prevention, but described barriers such as lack of personal motivation and unsafe environment. Many participants believed that providing opportunities for socialization while walking and combining walking with health information sessions would facilitate participation in and maintenance of a walking program. Conclusions Korean immigrant seniors believe strongly that imbalance is a primary cause of stroke. Restoring balance as a way to prevent stroke is culturally special among Koreans and provides a conceptual base in culturally tailoring our stroke prevention walking intervention for Korean immigrant seniors. Implications for practice A stroke prevention walking program for Korean immigrant seniors may have greater impact by addressing beliefs about stroke causes and prevention such as physical and

    Patent foramen ovale (PFO) might be a risk factor for unexplained ("cryptogenic") stroke or transient ischemic attack (TIA). We sought to determine the efficacy and safety of transcatheter PFO closure compared with antithrombotic therapy for secondary prevention of cerebrovascular events among patients with cryptogenic stroke. We performed a systematic review and meta-analysis of MedLine and Embase (from inception to March 2013) for randomized controlled trials (RCTs) that compared transcatheter PFO closure with medical therapy in subjects with cryptogenic stroke. Data were independently extracted on trial conduct quality, baseline characteristics, efficacy, and safety events from published articles and appendices. Risk ratios (RRs) and 95% confidence intervals (CIs) for the composite of stroke or TIA, and adverse cardiovascular events including atrial fibrillation/flutter were constructed. Three RCTs of 2303 subjects with previous stroke, TIA, or systemic arterial embolism (mean age, 45.7 years; 47.3% women; mean follow-up, 2.6 years) were included. PFO closure did not significantly reduce the risk of recurrent stroke/TIA (3.7% vs 5.2%; RR, 0.73; 95% CI, 0.50-1.07; P = 0.10); however, an increased risk of incident atrial fibrillation/flutter was detected (3.8% vs 1.0%; RR, 3.67; 95% CI, 1.95-6.89; P < 0.0001). No significant heterogeneity was detected for any end point among subgroups of patients stratified according to age, sex, index cardiovascular event, device type, interatrial shunt size, and presence of an atrial septal aneurysm (all P interactions ≥ 0.09). Meta-analysis of RCTs that assessed transcatheter PFO closure for secondary prevention of cerebrovascular events in subjects with cryptogenic stroke does not demonstrate benefit compared with antithrombotic therapy, and suggests potential risks.

    Transient ischaemic attacks (TIAs) are highly prevalent conditions, with at least 46 000 people per year in the UK having a TIA for the first time. TIAs are a warning that the patient is at risk of further vascular events and the 90-day risk of vascular events following a TIA, excluding events within the first week after diagnosis when the risk is highest, can be as high as 18%. Immediate assessment of patients with TIA, either at accident and emergency, general practice and/or TIA clinics, is therefore required to address secondary prevention and prevent further vascular events. This article addresses the need for optimising secondary prevention in the acute period following a TIA of ischaemic origin to reduce the risk of further vascular events as per recent Cochrane review advice and presents a novel project, Stroke Prevention Rehabilitation Intervention Trial of Exercise (SPRITE), to do this. One novel way to tackle vascular risk factors and promote secondary prevention in patients with TIA could be to adapt a cardiac rehabilitation programme for these patients. SPRITE, a feasibility and pilot study (ClinicalTrials.gov Identifier: NCT02712385) funded by the National Institute for Health Research, is attempting to adapt a home-based cardiac rehabilitation programme, 'The Healthy Brain Rehabilitation Manual', for use in the acute period following a TIA. The use of cardiac rehabilitation programmes post-TIA requires further research, particularly within the primary care setting.

    Prior studies indicate that young African-Americans (AA) have a greater frequency of ischemic stroke than similarly aged European-Americans (EA). We hypothesized that differences in stroke subtype frequency mediated through sex and differing risk factor profiles may play a role in ethnicity-specific stroke. Utilizing our biracial young-onset stroke population, we explored these relationships. Fifty nine hospitals in the Baltimore-Washington area participated in a population-based study of young-onset stroke in men (218-AA, 291-EA) and women (219-AA, 222-EA) aged 16-49. Data on age, sex, ethnicity and stroke risk factors (hypertension (HTN) and smoking) were gathered through standardized interview. A pair of vascular neurologists adjudicated each case to determine TOAST subtype. Logistic regression analyses evaluating for differences in stroke risk factors by TOAST subtype were performed. Analyses controlling for age and sex demonstrated that AA were more likely to have a lacunar stroke than EA (OR = 1.61; 95% CI = 1.12-2.32; p = 0.011) when utilizing the other TOAST subtypes as the reference group. This effect was mediated by HTN, which increases the risk of lacunar stroke (OR = 2.03; 95% CI = 1.38-2.98; p = 0.0003) and large artery stroke (OR = 1.70; 95% CI = 1.01-2.88; p = 0.048) when controlling for sex, ethnicity, and age. Cases below age 40 were more likely to have a cardioembolic stroke than those above age 40 (OR = 1.62; 95% CI = 1.15-2.27; p = 0.006), controlling for sex and ethnicity. Lastly, current smokers were more likely to have a large artery stroke than non-smokers (OR = 1.79; 95% CI = 1.08-2.98; p = 0.024). Our population-based data demonstrate ethnic differences in ischemic stroke subtypes. These findings may help clarify mechanisms of stroke in young adults which may in part be driven by ethnic-specific differences in early-onset traditional risk factors, thereby indicating differing emphasis on workup and prevention.

  6. Stroke Prevention in Atrial Fibrillation: Focus on Latin America

    Full Text Available Abstract Atrial fibrillation (AF is the most common sustained cardiac arrhythmia, with an estimated prevalence of 1-2% in North America and Europe. The increased prevalence of AF in Latin America is associated with an ageing general population, along with poor control of key risk factors, including hypertension. As a result, stroke prevalence and associated mortality have increased dramatically in the region. Therefore, the need for effective anticoagulation strategies in Latin America is clear. The aim of this review is to provide a contemporary overview of anticoagulants for stroke prevention. The use of vitamin K antagonists (VKAs, eg, warfarin and aspirin in the prevention of stroke in patients with AF in Latin America remains common, although around one fifth of all AF patients receive no anticoagulation. Warfarin use is complicated by a lack of access to effective monitoring services coupled with an unpredictable pharmacokinetic profile. The overuse of aspirin is associated with significant bleeding risks and reduced efficacy for stroke prevention in this patient group. The non-VKA oral anticoagulants (NOACbs represent a potential means of overcoming many limitations associated with VKA and aspirin use, including a reduction in the need for monitoring and a reduced risk of hemorrhagic events. The ultimate decision of which anticoagulant drug to utilize in AF patients depends on a multitude of factors. More research is needed to appreciate the impact of these factors in the Latin American population and thereby reduce the burden of AF-associated stroke in this region.

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

    Full Text Available Objective To evaluate the evidence of migraine increasing the risk of stroke, so as to provide evidence-based foundation for primary prevention of stroke in patients with migraine.  Methods Taking migraine or migraine with aura, prevention and control, ischemia, hemorrhagic stroke, treatment or therapy as search terms, retrieve in databases such as PubMed and ScienceDirect, assisted by manual searching, in order to collect relevant literatures including clinical guidelines, systematic reviews, Meta-analysis, randomized controlled trials, clinical controlled trials, retrospective case analysis, case-observation studies and reviews. Jadad Scale was used to evaluate the quality of literature.  Results Twenty-four related articles were finally selected, including 5 clinical guidelines, 2 systematic reviews, 4 Meta-analyses, 2 randomized controlled trials, 10 case-observation studies and 1 review. Among them 20 were of high quality, while 4 were of low quality. The results were as follows: 1 migraine, particularly migraine with aura, significantly increased the risk of ischemic stroke, and the risk of women was higher than men. Smoking and oral contraceptives further increased the risk of stroke. 2 The risk of hemorrhagic stroke in migraine with aura patients was higher than that in general population. Migraine without aura did not appear to increase the risk of hemorrhagic stroke, and migraine was an independent risk factor for aneurysm rupture. 3 Frequency of migraine attacks, especially migraine with aura, and risk of ischemic stroke was positively correlated. 4 Patent foramen ovale (PFO was more common in young patients with cryptogenic stroke and migraineurs. However, closure of PFO was not indicated for preventing stroke in migraineurs. 5 Triptans, which was used to treat acute migraine, with a vasoconstrictor effect, may increase the risk of stroke, therefore prophylactic treatment of migraine was very important.  Conclusions Smoking

    2017-09-01

    B vitamin therapy lowers plasma total homocysteine concentrations, and might be a beneficial intervention for stroke prevention; however, cyanocobalamin (a form of vitamin B12) can accelerate decline in renal function and increase the risk of cardiovascular events in patients with impaired renal function. Although early trials did not show benefit in reduction of stroke, these results might have been due to harm in participants with impaired renal function. In patients with diabetic nephropathy, cyanocobalamin is harmful, whereas B vitamins appear to reduce cardiovascular events in study participants with normal renal function. Our meta-analysis of individual patient data from two large trials of B vitamin therapy (VISP and VITATOPS) indicates that patients with impaired renal function who are exposed to high-dose cyanocobalamin do not benefit from therapy with B vitamins for the prevention of stroke (risk ratio 1·04, 95% CI 0·84-1·27), however, patients with normal renal function who are not exposed to high-dose cyanocobalamin benefit significantly from this treatment (0.78, 0·67-0·90; interaction p=0·03). The potential benefits of B vitamin therapy with folic acid and methylcobalamin or hydroxycobalamin, instead of cyanocobalamin, to lower homocysteine concentrations in people at high risk of stroke warrant further investigation.

    With improved life expectancy and the aging population, the global burden of atrial fibrillation (AF) continues to increase, and with AF comes an estimated fivefold increased risk of ischaemic stroke. Prophylactic anticoagulant therapy is more effective in reducing the risk of ischaemic stroke in AF patients than acetylsalicylic acid or dual-antiplatelet therapy combining ASA with clopidogrel. Non-vitamin K antagonist oral anticoagulants are the standard of care for stroke prevention in patients with non-valvular AF. The optimal anticoagulant strategy to prevent thromboembolism in AF patients who are undergoing percutaneous coronary intervention and stenting, those who have undergone successful transcatheter aortic valve replacement and those with embolic stroke of undetermined source are areas of ongoing research. This article provides an update on three randomized controlled trials of rivaroxaban, a direct, oral factor Xa inhibitor, that are complete or are ongoing, in these unmet areas of stroke prevention: oPen-label, randomized, controlled, multicentre study explorIng twO treatmeNt stratEgiEs of Rivaroxaban and a dose-adjusted oral vitamin K antagonist treatment strategy in patients with Atrial Fibrillation who undergo Percutaneous Coronary Intervention (PIONEER AF-PCI) trial; the New Approach riVaroxaban Inhibition of factor Xa in a Global trial vs Aspirin to prevenT Embolism in Embolic Stroke of Undetermined Source (NAVIGATE ESUS) trial and the Global study comparing a rivAroxaban-based antithrombotic strategy to an antipLatelet-based strategy after transcatheter aortIc vaLve rEplacement to Optimize clinical outcomes (GALILEO) trial.

    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. 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. 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. 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.

    Full Text Available We report a case of progressive ischemic stroke due to a mobile plaque, in which carotid artery stenting successfully prevented further infarctions. A 78-year-old man developed acute multiple infarcts in the right hemisphere, and a duplex ultrasound showed a mobile plaque involving the bifurcation of the left common carotid artery. Maximal medical therapy failed to prevent further infarcts, and the number of infarcts increased with his neurological deterioration. Our present case suggests that the deployment of a closed-cell stent is effective to prevent the progression of the ischemic stroke due to the mobile plaque.

    2017-01-01

    Full Text Available Stroke and other cerebrovascular diseases are among the most common causes of death worldwide. Prevention of modifiable risk factors is a cost-effective approach to decrease the risk of stroke. Oxidative stress is regarded as the major flexible operative agent in ischemic brain damage. This review presents recent scientific advances in understanding the role of carotenoids as antioxidants in lowering stroke risk based on observational studies. We searched Medline using the following terms: (Carotenoids [MeSH] OR Carotenes [tiab] OR Carotene [tiab] OR “lycopene [Supplementary Concept]” [MeSH] OR lycopene [tiab] OR beta-Carotene [tiab] AND (stroke [MeSH] OR stroke [tiab] OR “Cerebrovascular Accident” [tiab] OR “Cerebrovascular Apoplexy” [tiab] OR “Brain Vascular Accident” [tiab] OR “Cerebrovascular Stroke” [tiab] AND (“oxidative stress” [MeSH] OR “oxidative stress”[tiab]. This search considered papers that had been published between 2000 and 2017. Recent studies indicated that high dietary intake of six main carotenoids (i.e., lycopene, <- and ®-carotene, lutein, zeaxanthin, and astaxanthin was associated with reduced risk of stroke and other cardiovascular outcomes. However, the main mechanism of the action of these nutrients was not identified, and multiple mechanisms except antioxidant activity were suggested to be involved in the observed beneficial effects. The dietary intake of six major carotenoids should be promoted as this may have a substantial positive effect on stroke prevention and stroke mortality reduction.

    Hypertension (HT) is considered the main classic vascular risk factor for stroke and the importance of lowering blood pressure (BP) is well established. However, not all the benefit of antihypertensive treatment is due to BP reduction per se, as the effect of reducing the risk of stroke differs among classes of antihypertensive agents. Extensive evidences support that angiotensin-converting enzyme inhibitors (ACEI), angiotensin II receptor blockers (ARB), dihydropyridine calcium channel blockers (CCB) and thiazide diuretics each reduced risk of stroke compared with placebo or no treatment. Therefore, when combination therapy is required, a combination of these antihypertensive classes represents a logical approach. Despite the efficacy of antihypertensive therapy a large proportion of the population, still has undiagnosed or inadequately treated HT, and remain at high risk of stroke. In primary stroke prevention current guidelines recommend a systolic/diastolic BP goal of market of the fixed-dose combination (FDC) of ACEI or ARB and CCB should provide a better control of BP. However to confirm the efficacy of the FDC in primary stroke prevention, clinical intervention trials are needed.

  1. New oral anticoagulants are not superior to warfarin in secondary prevention of stroke or transient ischemic attacks, but lower the risk of intracranial bleeding: insights from a meta-analysis and indirect treatment comparisons.

    Directory of Open Access Journals (Sweden)

    Partha Sardar

    Full Text Available PURPOSE: Patients with Atrial Fibrillation (AF and prior stroke are classified as high risk in all risk stratification schemes. A systematic review and meta-analysis was performed to compare the efficacy and safety of New Oral Anticoagulants (NOACs to warfarin in patients with AF and previous stroke or transient ischemic attack (TIA. METHODS: Three randomized controlled trials (RCTs, including total 14527 patients, comparing NOACs (apixaban, dabigatran and rivaroxaban with warfarin were included in the analysis. Primary efficacy endpoint was ischemic stroke, and primary safety endpoint was intracranial bleeding. Random-effects models were used to pool efficacy and safety data across RCTs. RevMan and Stata software were used for direct and indirect comparisons, respectively. RESULTS: In patients with AF and previous stroke or TIA, effects of NOACs were not statistically different from that of warfarin, in reduction of stroke (Odds Ratio [OR] 0.86, 95% confidence interval [CI] 0.73- 1.01, disabling and fatal stroke (OR 0.85, 95% CI 0.71-1.04, and all-cause mortality (OR 0.90, 95% CI 0.79 -1.02. Randomization to NOACs was associated with a significantly lower risk of intracranial bleeding (OR 0.42, 95% CI 0.25-0.70. There were no major differences in efficacy between apixaban, dabigatran (110 mg BID and 150 mg BID and rivaroxaban. Major bleeding was significantly lower with apixaban and dabigatran (110 mg BID compared with dabigatran (150 mg BID and rivaroxaban. CONCLUSION: NOACs may not be more effective than warfarin in the secondary prevention of ischemic stroke in patients with a prior history of cerebrovascular ischemia, but have a lower risk of intracranial bleeding.

    Full Text Available Abstract The cornerstone in clinical evidence of the relative efficacy of thienopyridines (clopidogrel, ticlopidine versus aspirin in the secondary prevention of vascular disease is the Clopidogrel versus Aspirin in Patients at Risk of Ischaemic Events trial. This trial showed a modest benefit in the reduction of vascular events by clopidogrel. The results differed according to qualifying disorder: myocardial infarction, -3.7%; ischaemic stroke, +7.3%; and peripheral arterial disease, +23.8% (P = 0.042. Similar results were found for ticlopidine after brain ischaemia. The safety of clopidogrel appears to be similar to that of aspirin and better than that of ticlopidine. However, the recent report of thrombotic thrombocytopenic purpura in association with clopidogrel causes concern.

    Rationale Stroke is a major cause of death and disability worldwide, yet 80% of strokes can be prevented through modifications of risk factors and lifestyle and by medication. While management strategies for primary stroke prevention in high cardiovascular disease risk individuals are well established, they are underutilized and existing practice of primary stroke prevention are inadequate. Behavioral interventions are emerging as highly promising strategies to improve cardiovascular disease risk factor management. Health Wellness Coaching is an innovative, patient-focused and cost-effective, multidimensional psychological intervention designed to motivate participants to adhere to recommended medication and lifestyle changes and has been shown to improve health and enhance well-being. Aims and/or hypothesis To determine the effectiveness of Health Wellness Coaching for primary stroke prevention in an ethnically diverse sample including Māori, Pacific Island, New Zealand European and Asian participants. Design A parallel, prospective, randomized, open-treatment, single-blinded end-point trial. Participants include 320 adults with absolute five-year cardiovascular disease risk ≥ 10%, calculated using the PREDICT web-based clinical tool. Randomization will be to Health Wellness Coaching or usual care groups. Participants randomized to Health Wellness Coaching will receive 15 coaching sessions over nine months. Study outcomes A substantial relative risk reduction of five-year cardiovascular disease risk at nine months post-randomization, which is defined as 10% relative risk reduction among those at moderate five-year cardiovascular disease risk (10-15%) and 25% among those at high risk (>15%). Discussion This clinical trial will determine whether Health Wellness Coaching is an effective intervention for reducing modifiable risk factors, and hence decrease the risk of stroke and cardiovascular disease.

    Drawing on the perspectives of stroke survivors, family members and domestic helpers, this study explores participants' experiences of self-perceived fall risk factors after stroke, common fall prevention strategies used, and challenges to community participation after a fall. Semi-structured interviews were conducted in Singapore with community-dwelling stroke survivors with a previous fall (n = 9), family caregivers (n = 4), and domestic helpers (n = 4) who have cared for a stroke survivor with a previous fall. Purposive sampling was used for recruitment; all interviews were audio-recorded with permission and transcribed. Thematic analysis was conducted using NVivo (v10) software. All participants shared their self-perceived intrinsic and extrinsic fall risk factors and main challenges after a fall. For stroke participants and family caregivers, motivational factors in developing safety strategies after a previous fall(s) include social connectedness, independent living and community participation. For family caregivers and domestic helpers, the stroke survivor's safety is their top priority, however this can also lead to over-protective behavior outside of the rehabilitation process. Reducing the risk of falls in community-dwelling stroke survivors seems to be more important than promoting community participation among caregivers. The study findings highlight that a structured and client-centered fall prevention program targeting stroke survivors and caregivers is needed in Singapore. Implications for rehabilitation Falls after stroke can lead to functional decline in gait and mobility and restricted self-care activities. Community-dwelling stroke survivors develop adaptive safety strategies after a fall and want to be socially connected. However, caregivers see the safety of the stroke survivors as their top priority and demonstrate over-protective behaviors. Fall prevention programs for community-dwelling stroke survivors should target both stroke

    We sought to evaluate the success rates in achieving preventive therapeutic goals in patients who experienced an ischemic stroke (IS) and compare them with those achieved in patients with coronary artery disease (CAD). This was an observational multicenter case-control study (3 patients with IS and one control subject with CAD) performed in 1444 primary health centers in Spain. Preventive therapeutic objectives according to American Heart Association guidelines were predefined. Demographic data, vascular risk factors, and success/failure in achievement of objectives were recorded and compared between patients with IS and CAD. A total of 5458 patients were included, 4098 (75.1%) had IS and 1360 (24.9%) had CAD. Although more than 90% of patients with hypertension, diabetes, or dyslipidemia were under specific drug regimens, only about 25% achieved the recommended therapeutic objective for each risk factor. Success rate was especially low among patients with IS compared with CAD: hypertension (23.8% v 27.2%; P = .028); dyslipidemia (13.6% v 20.3%; P risk factors under control, compared with 5.6% of those with CAD (P = .006). For all patients, multivariate logistic regression model showed that independent predictors of full risk factor control were: presence of CAD as compared with IS (odds ratio [OR] 2.11; 95% confidence interval [CI] 1.35-3.29; P = .001), older age (OR 1.02; 95% CI 1.00-1.04; P = .028), and having less than 3 risk factors (OR 16.98; 95% CI 9.02-31.97; P risk factor control.

    The primary prevention of cardiovascular disease is a public health priority. To assess the costs and benefits of a Polypill Prevention Programme using a daily 4-component polypill from age 50 in the UK, we determined the life years gained without a first myocardial infarction (MI) or stroke, together with the total service cost (or saving) and the net cost (or saving) per year of life gained without a first MI or stroke. This was estimated on the basis of a 50 % uptake and a previously published 83 % treatment adherence. The total years of life gained without a first MI or stroke in a mature programme is 990,000 each year in the UK. If the cost of the Polypill Prevention Programme were £1 per person per day, the total cost would be £4.76 bn and, given the savings (at 2014 prices) of £2.65 bn arising from the disease prevented, there would be a net cost of £2.11 bn representing a net cost per year of life gained without a first MI or stroke of £2120. The results are robust to sensitivity analyses. A national Polypill Prevention Programme would have a substantial effect in preventing MIs and strokes and be cost-effective.

    Lowering blood pressure (BP) in stroke survivors reduces the risk of recurrent stroke. We tested the hypothesis that a nurse-led nonpharmacologic intervention would lower the BP of participants in an intervention group compared with a control group. A total of 349 patients who had sustained acute...... with antihypertensive therapy, and 92% of the hypertensive patients in the intervention group followed the advice to see a general practitioner (GP) for BP checkups. At follow-up, 187 patients (62%) were hypertensive, with no difference in the rate of hypertension seen between the groups. Our data indicate that home...... visits by nurses did not result in a lowering of BP. Patients complied with antihypertensive therapy and GP visits in the case of hypertension. Nonetheless, the majority of patients were hypertensive at the 1-year follow up....

    Anticoagulation is the therapeutic paradigm for stroke prevention in patients with atrial fibrillation (AF). It is unknown how physicians make treatment decisions in primary stroke prevention for patients with AF. To evaluate the association between family physicians' risk preferences (aversion risk and ambiguity) and therapeutic recommendations (anticoagulation) in the management of AF for primary stroke prevention by applying concepts from behavioral economics. Overall, 73 family physicians participated and completed the study. Our study comprised seven simulated case vignettes, three behavioral experiments, and two validated surveys. Behavioral experiments and surveys incorporated an economic framework to determine risk preferences and biases (e.g., ambiguity aversion, willingness to take risks). The primary outcome was making the correct decision of anticoagulation therapy. Secondary outcomes included medical errors in the management of AF for stroke prevention. Overall, 23.3% (17/73) of the family physicians elected not to escalate the therapy from antiplatelets to anticoagulation when recommended by best practice guidelines. A total of 67.1% of physicians selected the correct therapeutic options in two or more of the three simulated case vignettes. Multivariate analysis showed that aversion to ambiguity was associated with appropriate change to anticoagulation therapy in the management of AF (OR 5.48, 95% CI 1.08-27.85). Physicians' willingness to take individual risk in multiple domains was associated with lower errors (OR 0.16, 95% CI 0.03-0.86). Physicians' aversion to ambiguity and willingness to take risks are associated with appropriate therapeutic decisions in the management of AF for primary stroke prevention. Further large scale studies are needed.

  10. Minimally invasive soft tissue release of foot and ankle contracture secondary to stroke.

    Boffeli, Troy J; Collier, Rachel C

    2014-01-01

    Lower extremity contracture associated with stroke commonly results in a nonreducible, spastic equinovarus deformity of the foot and ankle. Rigid contracture deformity leads to gait instability, pain, bracing difficulties, and ulcerations. The classic surgical approach for stroke-related contracture of the foot and ankle has been combinations of tendon lengthening, tendon transfer, osteotomy, and joint fusion procedures. Recovery after traditional foot and ankle reconstructive surgery requires a period of non-weightbearing that is not typically practical for these patients. Little focus has been given in published studies on minimally invasive soft tissue release of contracture. We present the case of a 61-year-old female with an equinovarus foot contracture deformity secondary to stroke. The patient underwent Achilles tendon lengthening, posterior tibial tendon Z lengthening, and digital flexor tenotomy of each toe with immediate weightbearing in a walking boot, followed by transition to an ankle-foot orthosis. The surgical principles and technique tips are presented to demonstrate our minimally invasive approach to release of foot and ankle contracture secondary to stroke. The main goal of this approach is to improve foot and ankle alignment for ease of bracing, which, in turn, will improve gait, reduce the risk of falls, decrease pain, and avoid the development of pressure sores.

    Supplementation with B vitamins for stroke prevention has been evaluated over the years, but which combination of B vitamins is optimal for stroke prevention is unclear. We performed a network meta-analysis to assess the impact of different combinations of B vitamins on risk of stroke. A total of 17 trials (86 393 patients) comparing 7 treatment strategies and placebo were included. A network meta-analysis combined all available direct and indirect treatment comparisons to evaluate the efficacy of B vitamin supplementation for all interventions. B vitamin supplementation was associated with reduced risk of stroke and cerebral hemorrhage. The risk of stroke was lower with folic acid plus vitamin B6 as compared with folic acid plus vitamin B12 and was lower with folic acid plus vitamin B6 plus vitamin B12 as compared with placebo or folic acid plus vitamin B12. The treatments ranked in order of efficacy for stroke, from higher to lower, were folic acid plus vitamin B6 > folic acid > folic acid plus vitamin B6 plus vitamin B12 > vitamin B6 plus vitamin B12 > niacin > vitamin B6 > placebo > folic acid plus vitamin B12. B vitamin supplementation was associated with reduced risk of stroke; different B vitamins and their combined treatments had different efficacy on stroke prevention. Folic acid plus vitamin B6 might be the optimal therapy for stroke prevention. Folic acid and vitamin B6 were both valuable for stroke prevention. The efficacy of vitamin B12 remains to be studied.

    2006-01-01

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

    Concepts and our approaches to stroke prevention in atrial fibrillation (AF) have changed markedly over the last decade. There has been an evolution over the approach to stroke and bleeding risk assessment, as well as new treatment options. An increasing awareness of AF has led to calls to improve the detection of and population screening for AF. Stroke and bleeding risk assessment continues to evolve, and the ongoing debate on balance between simplicity and practicality, against precision medicine will continue. In this review article, we provide an overview of past, present and the (likely) future concepts and approaches to stroke prevention in AF. We propose three simple steps (the Birmingham '3-step') that offers a practical management pathway to help streamline and simplify decision-making for stroke prevention in patients with AF.

  16. 2017 consensus of the Asia Pacific Heart Rhythm Society on stroke prevention in atrial fibrillation

    Chern-En Chiang, MD, PhD

    2017-08-01

    Full Text Available Atrial fibrillation (AF is the most common sustained arrhythmia, causing a 2-fold increase in mortality and a 5-fold increase in stroke. The Asian population is rapidly aging, and in 2050, the estimated population with AF will reach 72 million, of whom 2.9 million may suffer from AF-associated stroke. Therefore, stroke prevention in AF is an urgent issue in Asia. Many innovative advances in the management of AF-associated stroke have emerged recently, including new scoring systems for predicting stroke and bleeding risks, the development of non-vitamin K antagonist oral anticoagulants (NOACs, knowledge of their special benefits in Asians, and new techniques. The Asia Pacific Heart Rhythm Society (APHRS aimed to update the available information, and appointed the Practice Guideline sub-committee to write a consensus statement regarding stroke prevention in AF. The Practice Guidelines sub-committee members comprehensively reviewed updated information on stroke prevention in AF, emphasizing data on NOACs from the Asia Pacific region, and summarized them in this 2017 Consensus of the Asia Pacific Heart Rhythm Society on Stroke Prevention in AF. This consensus includes details of the updated recommendations, along with their background and rationale, focusing on data from the Asia Pacific region. We hope this consensus can be a practical tool for cardiologists, neurologists, geriatricians, and general practitioners in this region. We fully realize that there are gaps, unaddressed questions, and many areas of uncertainty and debate in the current knowledge of AF, and the physician׳s decision remains the most important factor in the management of AF.

  17. Blood pressure as a therapeutic target in stroke.

    2009-01-01

    Stroke, as a clinical manifestation of the cardiovascular diseases, is one of the leading causes of death and disability in both developed and developing countries. Hypertension is by far, the most important risk factor for stroke. Epidemiological data indicate that the risk of stroke increases with both systolic and diastolic blood pressure elevation, from levels of 115/75 mmHg. It is also evident that most adults worldwide have values above these limits, thus emphasizing the importance of blood pressure as a risk factor for stroke. Clinical trials of antihypertensive treatment, both in studies that have compared active drugs against placebo or in those comparing different types of drugs have clearly demonstrated a protective effect of blood pressure reduction in the prevention of stroke. The degree of protection is directly related to blood pressure reduction and, the lower the level, the better the prognosis. Although data on secondary stroke prevention are scarcer, studies also seem to indicate that lowering blood pressure with antihypertensive treatment protects against stroke recurrence. At the present moment there is still uncertainty on 2 different aspects regarding the relationship between antihypertensive treatment and stroke. First, the blood pressure management during acute stroke has not adequately investigated in clinical trials. Second, the possibility of a protective role of specific types of antihypertensive drugs beyond blood pressure reduction is a matter of debate. Independently of these unresolved issues, prevention of hypertension development by lifestyle changes and adequate treatment and control to the hypertensive population will be a very effective measure in reducing stroke incidence, stroke recurrence, and stroke mortality.

    2018-05-21

    Treatment recommendations for pregnancy associated ischemic stroke are scarce. This may be due to the fact that, in general, obstetricians tend not to make recommendations for stroke patients and neurologists are not commonly involved in the care of pregnant women. Herein, we review the multiple etiologies of ischemic stroke during pregnancy, considerations for diagnostic testing, and acute treatment and prevention options, including associated risks specific to the pregnant and puerperal state. Intravenous tissue plasminogen activator (tPA) and endovascular thrombectomy have been used successfully to treat pregnant women with acute ischemic stroke. Recent national guidelines recommend considering tPA use during pregnancy for moderate and severe strokes if the potential benefits offset the risks of uterine hemorrhage. Pregnancy-associated ischemic stroke is rare, but can be devastating, and recanalization therapy should not be systematically withheld. Women who are at risk for stroke should be followed carefully, and providers caring for pregnant women should be educated regarding stroke signs and symptoms. Many of the standard post stroke diagnostic modalities may be used safely in pregnancy, and primary and secondary stroke prevention therapy must be tailored to avoid fetal toxicity.

    An increased interarm systolic blood pressure (SBP) difference of ≥10 mm Hg is associated with increased cardiovascular risk and a difference of ≥15 mm Hg with increased cerebrovascular risk. The stroke population presents a high-risk group for future cardiovascular and cerebrovascular events and therefore estimation of interarm SBP difference as a predictive tool may assist with further secondary stroke prevention. The aim of the study was to determine the prevalence of interarm SBP and diastolic blood pressure difference in a post-stroke population. A comprehensive assessment of secondary risk factors along with blood pressure measurements were taken 6-months' post-ischemic stroke from the Action on Secondary Prevention Interventions and Rehabilitation in Stroke cohort. Descriptive and logistic regression analyses were performed. Odds ratios and 95% confidence intervals are presented. Two hundred thirty-eight (M: F,139:99; mean age, 68.4 years) of 256 patients followed up at 6 months post-stroke had suitable blood pressure readings from both arms. Ninety-six patients (40.3%) had an interarm SBP difference of ≥10 mm Hg and 49 (20.6%) had a difference of ≥15 mm Hg. A history of hypertension, diabetes, smoking, and obesity was not significantly associated with an increased risk of interarm SBP difference. After multivariate logistic analysis, a history of alcohol excess was associated with an increased IASBP ≥15 mm Hg (odds ratio 2.32, 95% confidence interval 1.03-5.22). We have demonstrated that interarm SBP difference is commonly seen in a post stroke population. Copyright © 2017 American Society of Hypertension. Published by Elsevier Inc. All rights reserved.

    To determine the cost-effectiveness of lipid-lowering therapy in the secondary prevention of cardiovascular events in the Philippines. A cost-utility analysis was performed by using Markov modeling in the secondary prevention setting. The models incorporated efficacy of lipid-lowering therapy demonstrated in randomized controlled trials and mortality rates obtained from local life tables. Average and incremental cost-effectiveness ratios were obtained for simvastatin, atorvastatin, pravastatin, and gemfibrozil. The costs of the following were included: medications, laboratory examinations, consultation and related expenses, and production losses. The costs were expressed in current or nominal prices as of the first quarter of 2010 (Philippine peso). Utility was expressed in quality-adjusted life-years gained. Sensitivity analyses were performed by using variations in the cost centers, discount rates, starting age, and differences in utility weights for stroke. In the analysis using the lower-priced generic counterparts, therapy using 40 mg simvastatin daily was the most cost-effective option compared with the other therapies, while pravastatin 40 mg daily was the most cost-effective alternative if the higher-priced innovator drugs were used. In all sensitivity analyses, gemfibrozil was strongly dominated by the statins. In secondary prevention, simvastatin or pravastatin were the most cost-effective options compared with atorvastatin and gemfibrozil in the Philippines. Gemfibrozil was strongly dominated by the statins. Copyright © 2013 International Society for Pharmacoeconomics and Outcomes Research (ISPOR). Published by Elsevier Inc. All rights reserved.

    Full Text Available Introduction: Management of stroke in the remote rural areas in India faces major challenges because of lack of awareness. Stroke care services can be optimally implemented only if the communities have an understanding of the disease. Method: A population based, cross sectional survey of an adult general population sample between the ages of 31-60 years in a rural block in Tamil Nadu, India was carried out to study their knowledge, attitude, beliefs about cause, signs and symptoms, preventive measures and treatment options of stroke. Results: Of the 174 subjects studied only 69% were aware of the term stroke and 63% were able to list the symptoms. Only a little more than half the participants (58% were aware that diabetes, smoking and hypertension are risk factors for stroke. None of the participants were aware of the endovascular thrombolysis injection for better recovery from stroke. About quarter (23% of the participants did not think that the stroke is an emergency condition and they need to take the patient urgently to the hospital. Only 56% of the participants had checked their blood pressure and 49% for diabetes. A history of having either hypertension or diabetes and stroke in the family was the only factor that was significantly associated with better awareness (p=<0.001 independent of other potential facilitating factors including age, occupation, education and gender. Conclusion: There is a need to educate the rural communities about the risk factors, how to recognize the onset, the preventive measures and optimum care of stroke to reduce the burden.

  3. [Ischemic stroke in the young adult].

    2016-01-01

    Ischemic stroke is not rare in young adults since one in ten stroke patients are less than 50 years old. This incidence increased over the past last years, mainly due to the rise in the prevalence of traditional vascular risk factors in this sub-group of age but also of illegal drug use. Even though both survival and functional outcome of young stroke patients are better than those observed in older patients, socio-economic and quality of life consequences make this disease a main objective in terms of primary and secondary prevention. Identifying the cause of ischemic stroke in young adults is of major importance to prevent stroke recurrence. However, given the wide variety of potential underlying causes, the etiologic work-up of stroke in young adults requires a different approach from that in the elderly. In this context, a sequential diagnostic work-up is needed in order to optimize the yield of diagnostic tests, to reduce their cost and risks for the patient. Arterial dissection is the most frequent cause of stroke in young adults but other less frequent causes are numerous. Despite a comprehensive work-up, about one third of cases remains unexplained leading to the diagnosis of cryptogenic ischemic stroke.

    (1) To demonstrate the importance of nutrition, especially sodium restriction and increased potassium and protein intakes, in the prevention of hypertension and stroke in a pilot study involving senior citizens. (2) To design a population-based intervention in the Shimane Prefecture of Japan concerning dietary factors such as low sodium and high potassium, protein, magnesium, calcium and dietary fibre in the prevention of stroke. The intervention study was carried out at a senior citizens' residence and included general health education along with a reduction of dietary salt intake and increases in vegetable and protein, especially from seafood. Sixty-three healthy senior citizens (average age: 74.8 +/- 7.7 years) had their daily meals modified to a low sodium/potassium ratio for four weeks without their knowledge by the use of a potassium chloride substitute for salt, soy sauce and bean paste, which contains much less sodium and more potassium. Monosodium L-glutamate monohydrate used for cooking was changed to monopotassium L-glutamate monohydrate. Blood pressure was measured with the patient in the sitting position. Daily dietary sodium and potassium intakes were assessed by flame photometry from 24-hour urine specimens. Extensive intervention programs were introduced into the Shimane Prefecture, which has a population of 750,000, through health education classes for housewives, home visits by health nurses and an educational TV program for dietary improvement. The mortality from stroke was monitored for 10 years and compared with the average in Japan. The blood pressure lowering effect of reducing the dietary sodium/potassium ratio was confirmed through a pilot intervention study at the senior citizens' residence. The mortality rates for stroke in the middle-aged population from the Shimane Prefecture during the 10 years after the introduction of dietary improvement had a steeper decline in hemorrhagic, ischemic and all strokes than the average for Japan.

    Stroke is one of the most common causes of mortality and morbidity worldwide. Hemorrhagic stroke comprises 10-20% of strokes. Here, we present a case report of hemorrhagic stroke that may have been secondary to untreated Obstructive Sleep Apnea (OSA) in a young man with no other cardiovascular risk factors or features of metabolic syndrome. A 32-year-old man was admitted for hemorrhagic stroke. An initial thorough workup for the etiology of stroke was inconclusive. Eventually, a polysomnography was done, which demonstrated OSA suggesting that untreated OSA may have contributed to his stroke. OSA may cause hemorrhagic stroke by nocturnal blood pressure surge. So, all physicians should consider doing polysomnography for unexplained hemorrhagic stroke or in patients at risk. Diagnosing and treating OSA would be critical in preventing hemorrhagic stroke and its recurrences.

  7. Dizziness in stroke

    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.

  10. Chronic Management of Hypertension after Stroke: The Role of Ambulatory Blood Pressure Monitoring

    Science.gov (United States)

    Castilla-Guerra, Luis; Fernandez-Moreno, Maria del Carmen

    2016-01-01

    Hypertension is the most important potentially reversible risk factor for stroke in all age groups; high blood pressure (BP) is also associated with increased risk of recurrent stroke in patients who have already had an ischemic or hemorrhagic event. Twenty-four hour ambulatory BP monitoring (ABPM) has become an important tool for improving the diagnosis and management of hypertension, and is increasingly used to assess patients with hypertension. Nevertheless, although ABPM devices are increasingly used for assessment of hypertension, their value in the chronic management of hypertension in patients with stroke has not been systematically studied. In fact, among large-scale randomized trials for secondary stroke prevention, only the Morbidity and Mortality After Stroke, Eprosartan Compared With Nitrendipine for Secondary Prevention trial included 24-hour ABPM. ABPM has demonstrated chronic disruption of the circadian rhythm of BP after acute phase of stroke and has shown higher sensitivity compared to office BP in evaluating the effectiveness of antihypertensive treatment among stroke survivors. High 24-hour BP is an independent predictor for cerebrovascular events, brain microbleeds, and subsequent development of dementia. Nevertheless, although stroke care guidelines endorse the importance of hypertension management, the specific role of ABPM among stroke survivors after the acute phase of disease has not been established. Further studies are needed to clarify whether routine application of ABPM among these patients should be recommended. PMID:26687120

    Peptic ulcer has been associated with an increased risk of stroke. This study aimed to evaluate the impacts of peptic ulcer on stroke recurrence and mortality. Patients with first-ever ischemic stroke were retrospectively confirmed with or without a history of peptic ulcer. The primary end point was defined as fatal and nonfatal stroke recurrence. Risks of 1-year fatal and nonfatal stroke recurrence were analyzed with the Kaplan-Meier method. Predictors of fatal and nonfatal stroke recurrence were evaluated with the Cox proportional hazards model. Among the 2577 enrolled patients with ischemic stroke, 129 (5.0%) had a history of peptic ulcer. The fatal and nonfatal stroke recurrence within 1 year of the index stroke was higher in patients with peptic ulcer than in patients without peptic ulcer (12.4% versus 7.2%, P = .030). Cox proportional hazards model detected that age (hazard ratio [HR] = 1.018, 95% confidence interval [CI] 1.005-1.031, P = .008), hypertension (HR = 1.397, 95% CI 1.017-1.918, P = .039), and history of peptic ulcer (HR = 1.853, 95% CI 1.111-3.091, P = .018) were associated with stroke recurrence. Ischemic stroke patients with peptic ulcer may have an increased risk of stroke recurrence. The results emphasize the importance of appropriate prevention and management of peptic ulcer for secondary stroke prevention. Copyright © 2018 National Stroke Association. Published by Elsevier Inc.

  14. Hypercholesterolemia, Stroke And Statins

    Directory of Open Access Journals (Sweden)

    2005-01-01

    Full Text Available The link between serum cholesterol levels and the incidence of stroke still remain to be established. There are conflicting reports from a series of observational cohort studies. However, clinical trials with HMG CoA reductase inhibitors (also called statins have shown that cholesterol lowering therapy used in the primary and secondary prevention of myocardial infarction significantly reduced cardiovascular events including strokes. Meta analysis of trials with statins have shown a relative risk reduction in stroke of 12 to 48% in patients with coronary heart disease after MI. It has been postulated that the clinical action of statins is the result of pleiotropic / antiatherogenic effects rather than simply a reduction in cholesterol. The putative beneficial effect of statins in stroke involve blocking of macrophage and platelet activation, improvement of endothelial cell vasomotor function, enhancement of endothelial fibrinolytic function, immunosuppressive and anti-inflammatory action, inhibition of smooth muscle cell proliferation and particularly enhancement of endothelial nitric oxide synthase (eNOS.

  15. Rehabilitation and education are underutilized for mild stroke and TIA sufferers.

    Faux, Steven G; Arora, Pooja; Shiner, Christine T; Thompson-Butel, Angelica G; Klein, Linda A

    2018-06-01

    Transient ischemic attack (TIA) and mild stroke represent a large proportion of cerebrovascular events, at high risk of being followed by recurrent, serious events. The importance of early education addressing risk management, secondary prevention and lifestyle modifications is the centerpiece of further stroke prevention. However, delivering education and rehabilitation to this population can be complex and challenging. Via synthesis of a narrative review and clinical experience, we explore the unique and inherent complexities of rehabilitation management and education provision for patients following mild stroke and TIA. A considerable proportion of TIA/mild stroke survivors have ongoing rehabilitation needs that are poorly addressed. The need for rehabilitation in these patients is often overlooked, and available assessment tools lack the sensitivity to identify common subtle impairments in cognition, mood, language and fatigue. Active and accessible education interventions need to be initiated early after the event, and integrated with ongoing rehabilitation management. Priority areas in need of future development in this field are highlighted and discussed. Implications for rehabilitation Survivors of mild stroke and TIA have ongoing unmet rehabilitation needs and require a unique approach to rehabilitation and education. Rehabilitation needs are difficult to assess and poorly addressed in this cohort, where available assessment tools lack the sensitivity required to identify subtle impairments. Education needs to be initiated early after the event and involve active engagement of the patient in order to improve stroke knowledge, mood and motivate adherence to lifestyle modifications and secondary prevention. Rehabilitation physicians are currently an underutilized resource, who should be more involved in the management of all patients following TIA or mild stroke.

  16. Sodium Valproate, a Histone Deacetylase Inhibitor, Is Associated With Reduced Stroke Risk After Previous Ischemic Stroke or Transient Ischemic Attack

    Brookes, Rebecca L.; Crichton, Siobhan; Wolfe, Charles D.A.; Yi, Qilong; Li, Linxin; Hankey, Graeme J.; Rothwell, Peter M.

    2018-01-01

    Background and Purpose— A variant in the histone deacetylase 9 (HDAC9) gene is associated with large artery stroke. Therefore, inhibiting HDAC9 might offer a novel secondary preventative treatment for ischemic stroke. The antiepileptic drug sodium valproate (SVA) is a nonspecific inhibitor of HDAC9. We tested whether SVA therapy given after ischemic stroke was associated with reduced recurrent stroke rate. Methods— Data were pooled from 3 prospective studies recruiting patients with previous stroke or transient ischemic attack and long-term follow-up: the South London Stroke Register, The Vitamins to Prevent Stroke Study, and the Oxford Vascular Study. Patients receiving SVA were compared with patients who received antiepileptic drugs other than SVA using survival analysis and Cox Regression. Results— A total of 11 949 patients with confirmed ischemic event were included. Recurrent stroke rate was lower in patient taking SVA (17 of 168) than other antiepileptic drugs (105 of 530; log-rank survival analysis P=0.002). On Cox regression, controlling for potential cofounders, SVA remained associated with reduced stroke (hazard ratio=0.44; 95% confidence interval: 0.3–0.7; P=0.002). A similar result was obtained when patients taking SVA were compared with all cases not taking SVA (Cox regression, hazard ratio=0.47; 95% confidence interval: 0.29–0.77; P=0.003). Conclusions— These results suggest that exposure to SVA, an inhibitor of HDAC, may be associated with a lower recurrent stroke risk although we cannot exclude residual confounding in this study design. This supports the hypothesis that HDAC9 is important in the ischemic stroke pathogenesis and that its inhibition, by SVA or a more specific HDAC9 inhibitor, is worthy of evaluation as a treatment to prevent recurrent ischemic stroke.

    Full Text Available Branko N Huisa, Andrew B Stemer, Justin A ZivinDepartment of Neuroscience University of California, San Diego, CA, USAAbstract: Statin therapy in patients with cardiovascular disease is associated with reduced incidence of stroke. The Stroke Prevention by Aggressive Reduction of Cholesterol Levels (SPARCL trial showed daily treatment with 80 mg of atorvastatin in patients with a recent stroke or transient ischemic attack (TIA reduced the incidence of fatal or nonfatal stroke by 16%. Several post hoc analyses of different subgroups followed the SPARCL study. They have not revealed any significant differences when patients were sorted by age, sex, presence of carotid disease or type of stroke, with the exception of intracranial hemorrhage as the entry event. Lower low-density lipoprotein cholesterol levels in addition to possible neuroprotective mechanisms due to atorvastatin treatment correlate with improved risk reduction. Although not predefined subgroups and subject to an insufficient power, these post hoc studies have generated new clinical questions. However, clinicians should avoid denying therapy based on such subgroup analysis. At this point, the best evidence powerfully demonstrates stroke and TIA patients should be prescribed high dose statin therapy for secondary stroke prevention.Keywords: statins, intracranial hemorrhage, neuroprotection, outcome, prevention, carotid stenosis, transient ischemic attack

    To inform the development of a tailored behavioral stroke risk reduction intervention for ethnic minority seniors, we sought to explore gender differences in perceptions of stroke prevention and physical activity (walking). In collaboration with community-based organizations, we conducted 12 mixed-gender focus groups of African American, Latino, Chinese, and Korean seniors aged 60 years and older with a history of hypertension (89 women and 42 men). Transcripts were coded and recurring topics compared by gender. Women expressed beliefs that differed from men in 4 topic areas: 1) stroke-related interest, 2) barriers to walking, 3) facilitators to walking, and 4) health behavior change attitudes. Compared with men, women were more interested in their role in response to a stroke and post-stroke care. Women described walking as an acceptable form of exercise, but cited neighborhood safety and pain as walking barriers. Fear of nursing home placement and weight loss were identified as walking facilitators. Women were more prone than men to express active/control attitudes toward health behavior change. Older ethnic minority women, a high-risk population for stroke, may be more receptive to behavioral interventions that address the gender-specific themes identified by this study.

  20. Weight reduction for primary prevention of stroke in adults with overweight or obesity.

    Science.gov (United States)

    Curioni, C; André, C; Veras, R

    2006-10-18

    Obesity is seen as a worldwide chronic disease with high prevalence that has been associated with increased morbidity from many conditions including stroke, which is the third leading cause of death in developed countries and a leading cause of severe long-term disability. The causal association between overweight or obesity and stroke is unclear and there is no definite study clarifying the role of obesity treatment in the prevention of a first stroke (primary prevention). Given the prevalence of stroke and the enormous health and economic cost of the disease, it is important to establish the possible impact of weight reduction per se on stroke incidence. To assess the effects of weight reduction in people with overweight or obesity on stroke incidence. MEDLINE, EMBASE, The Cochrane Library, LILACS, databases of ongoing trials and reference lists were used to identify relevant trials. The last search was conducted in April 2006. Randomised controlled trials comparing any intervention for weight reduction (single or combined) with placebo or no intervention in overweight or obese people. No trials were found in the literature for inclusion in this review. There are currently no results to be reported. Obesity seems to be associated with an increased risk of stroke and it has been suggested that weight loss may lead to a reduction of stroke occurrence. However, this hypothesis is not based on strong scientific evidence resulting from randomised controlled clinical trials. This systematic review identified the urgent need for well-designed, adequately-powered, multi centre randomised controlled trials assessing the effects of weight reduction in persons with overweight or obesity on stroke occurrence.

    Although pharmacological treatment of hypertension has important health benefits, it does not capture the benefit of maintenance of ideal health through the prevention or delay of hypertension. A total of 26 875 black and white participants aged 45+ years were assessed and followed for incident stroke events. The association was assessed between incident stroke and: (1) systolic blood pressure (SBP)categorized as normal (pressure strata, the risk of stroke increased with each additional class of required antihypertensive medication, with hazard ratio [HR], 1.33; 95% confidence interval, 1.16 to 1.52 for normotensive, HR, 1.15; 95% confidence interval, 1.05 to 1.26 for prehypertension, and HR, 1.22; 95% confidence interval, 1.06 to 1.39 for stage 1 hypertension. A successfully treated (SBP<120 mm Hg) hypertensive person on 3+ antihypertensive medication classes was at marginally higher stroke risk than a person with untreated stage 1 hypertension (HR, 2.48 versus HR=2.19; relative to those with SBP <120 on no antihypertensive medications). Maintaining the normotensive status solely through pharmacological treatment has a profound impact, as nearly half of this general population cohort were treated to guideline (SBP<140 mm Hg) but failed to return to risk levels similar to normotensive individuals. Even with successful treatment, there is a substantial potential gain by prevention or delay of hypertension. © 2015 American Heart Association, Inc.

    2017-03-01

    The aim of this study was to evaluate the cost effectiveness of novel oral anticoagulants (NOACs) for stroke prevention among atrial fibrillation (AF) patients by incorporating Taiwanese demographic information derived from a population-based database, the National Health Insurance Research Database (NHIRD), into cost-effectiveness analysis. From 1 January to 31 December 2012, 98,213 AF patients were selected from the NHIRD database. A Markov model was constructed that combined published secondary data with the Taiwan NHIRD to compare the cost and incremental cost effectiveness of apixaban 5 mg twice daily, dabigatran 110 or 150 mg twice daily, rivaroxaban 20 mg once daily, and warfarin. The lifetime costs of warfarin, dabigatran 110 mg, dabigatran 150 mg, rivaroxaban 20 mg, and apixaban 5 mg were US$10,660, US$13,693, US$13,426, US$13,455, US$15,965, respectively. Apixaban resulted in an incremental cost effectiveness of US$39,351, US$27,039, US$41,298, and US$48,896 per quality-adjusted life-year (QALY) compared with warfarin, dabigatran 110 mg, dabigatran 150 mg, and rivaroxaban 20 mg, respectively. In Monte-Carlo analyses, apixaban 5 mg, rivaroxaban 20 mg, warfarin, and dabigatran 110 mg were cost effective in 83, 10.4, 7, and 0.8%, respectively, of the simulations using a willingness-to-pay (WTP) threshold of US$50,000 per QALY. Apixaban was more cost effective than warfarin, dabigatran, and rivaroxaban for stroke prevention in patients with AF. Among the anticoagulant therapies, the WTP threshold of apixaban was about US$50,000 per QALY gained. These cost-effectiveness estimations provide useful information to aid clinical decision making in stroke prevention for AF patients.

    Outpatient management safely and effectively prevents early recurrent stroke after transient ischaemic attack (TIA), but this approach may not be safe in patients with acute minor stroke. To study outcomes of clinic and hospital-referred patients with TIA or minor stroke (National Institute of Health Stroke Scale score ≤3) in a prospective, population-based study (Oxford Vascular Study). Of 845 patients with TIA/stroke, 587 (69%) were referred directly to outpatient clinics and 258 (31%) directly to inpatient services. Of the 250 clinic-referred minor strokes (mean age 72.7 years), 237 (95%) were investigated, treated and discharged on the same day, of whom 16 (6.8%) were subsequently admitted to hospital within 30 days for recurrent stroke (n=6), sepsis (n=3), falls (n=3), bleeding (n=2), angina (n=1) and nursing care (n=1). The 150 patients (mean age 74.8 years) with minor stroke referred directly to hospital (median length-of-stay 9 days) had a similar 30-day readmission rate (9/150; 6.3%; p=0.83) after initial discharge and a similar 30-day risk of recurrent stroke (9/237 in clinic patients vs 8/150, OR=0.70, 0.27-1.80, p=0.61). Rates of prescription of secondary prevention medication after initial clinic/hospital discharge were higher in clinic-referred than in hospital-referred patients for antiplatelets/anticoagulants (phospital-referred minor stroke versus £743 (1794) for clinic-referred cases. Outpatient management of clinic-referred minor stroke is feasible and may be as safe as inpatient care. Rates of early hospital admission and recurrent stroke were low and uptake and maintenance of secondary prevention was high.

  7. ESPRIT: is aspirin plus dipyridamole superior to aspirin alone in TIA or minor stroke patients?

    Science.gov (United States)

    Rouhl, R P W; Lodder, J

    2008-11-01

    Transient ischemic attack (TIA) or a (minor) ischemic stroke increases the risk of a recurrent stroke or death. Antiplatelet therapy with aspirin or clopidogrel is, in the absence of a potential cardiac embolic source, common practice to lower this risk. Until recently, adjuvant dipyridamole or low intensity oral anticoagulation were not generally prescribed in secondary prevention. In this article, we will summarize and discuss the published results of the European/Australasian Stroke Prevention in Reversible Ischemia Trial (ESPRIT). In this trial, treatments with anticoagulants, aspirin alone and the combination of aspirin plus dipyridamole were compared, in a multicenter, three-armed, randomized, open-label study in patients with TIA or minor stroke.

    Intensive risk factor modification significantly improves outcomes for patients with diabetes mellitus and cardiovascular disease. However, the degree to which secondary prevention treatment goals are achieved in international clinical practice is unknown. Attainment of 5 secondary prevention parameters-aspirin use, lipid control (low-density lipoprotein cholesterol diabetes mellitus and known cardiovascular disease at entry into TECOS (Trial Evaluating Cardiovascular Outcomes With Sitagliptin). Logistic regression was used to evaluate the association between individual and regional factors and secondary prevention achievement at baseline. Cox proportional hazards regression analysis was used to determine the association between baseline secondary prevention achievement and cardiovascular death, myocardial infarction, or stroke. Overall, 29.9% of patients with diabetes mellitus and cardiovascular disease achieved all 5 secondary prevention parameters at baseline, although 71.8% achieved at least 4 parameters. North America had the highest proportion (41.2%), whereas Western Europe, Eastern Europe, and Latin America had proportions of ≈25%. Individually, blood pressure control (57.9%) had the lowest overall attainment, whereas nonsmoking status had the highest (89%). Over a median 3.0 years of follow-up, a higher baseline secondary prevention score was associated with improved outcomes in a step-wise graded relationship (adjusted hazard ratio, 0.60; 95% confidence interval, 0.47-0.77 for those patients achieving all 5 measures versus those achieving ≤2). In an international trial population, significant opportunities exist to improve the quality of cardiovascular secondary prevention care among patients with diabetes mellitus and cardiovascular disease, which in turn could lead to reduced risk of downstream cardiovascular events.

    2013-09-15

    The \\'accuracy\\' of age, blood pressure, clinical features, duration and diabetes (ABCD(2)) scoring by non-stroke specialists referring patients to a daily Rapid Access Stroke Prevention (RASP) service is unclear, as is the accuracy of ABCD(2) scoring by trainee residents. In this prospective study, referrals were classified as \\'confirmed TIAs\\' if the stroke specialist confirmed a clinical diagnosis of possible, probable or definite TIA, and \\'non-TIAs\\' if patients had a TIA mimic or completed stroke. ABCD(2) scores from referring physicians were compared with scores by experienced stroke specialists and neurology\\/geriatric medicine residents at a daily RASP clinic; inter-observer agreement was examined. Data from 101 referrals were analysed (mean age=60.0years, 58% male). The median interval between referral and clinic assessment was 1day. Of 101 referrals, 52 (52%) were \\'non-TIAs\\': 45 (86%) of 52 were \\'TIA mimics\\' and 7 (14%) of 52 were completed strokes. There was only \\'fair\\' agreement in total ABCD(2) scoring between referring physicians and stroke specialists (κ=0.37). Agreement was \\'excellent\\' between residents and stroke specialists (κ=0.91). Twenty of 29 patients scored as \\'moderate to high risk\\' (score 4-6) by stroke specialists were scored \\'low risk\\' (score 0-3) by referring physicians. ABCD(2) scoring by referring doctors is frequently inaccurate, with a tendency to underestimate stroke risk. These findings emphasise the importance of urgent specialist assessment of suspected TIA patients, and that ABCD(2) scores by non-stroke specialists cannot be relied upon in isolation to risk-stratify patients. Inter-observer agreement in ABCD(2) scoring was \\'excellent\\' between residents and stroke specialists, indicating short-term training may improve accuracy.

    Full Text Available Abstract Background Falls are common in stroke survivors returning home after rehabilitation, however there is currently a lack of evidence about preventing falls in this population. This paper describes the study protocol for the FLASSH (FaLls prevention After Stroke Survivors return Home project. Methods and design This randomised controlled trial aims to evaluate the effectiveness of a multi-factorial falls prevention program for stroke survivors who are at high risk of falling when they return home after rehabilitation. Intervention will consist of a home exercise program as well as individualised falls prevention and injury minimisation strategies based on identified risk factors for falls. Additionally, two sub-studies will be implemented in order to explore other key areas related to falls in this population. The first of these is a longitudinal study evaluating the relationship between fear of falling, falls and function over twelve months, and the second evaluates residual impairment in gait stability and obstacle crossing twelve months after discharge from rehabilitation. Discussion The results of the FLASSH project will inform falls prevention practice for stroke survivors. If the falls prevention program is shown to be effective, low cost strategies to prevent falls can be implemented for those at risk around the time of discharge from rehabilitation, thus improving safety and quality of life for stroke survivors. The two sub-studies will contribute to the overall understanding and management of falls risk in stroke survivors.

    Full Text Available Extra cranial carotid artery stenosis is an important cause of stroke, which often needs treatment with carotid revascularization. To prevent stroke recurrence, carotid endarterectomy (CEA has been well-established for several decades for symptomatic high and moderate grade stenosis. Carotid stenting is a less invasive alternative to CEA and several recent trials have compared the efficacy of the 2 procedures in patients with carotid stenosis. Carotid artery stenting has emerged as a potential mode of therapy for high surgical risk patients with symptomatic high-grade stenosis. This review focuses on the current data available that will enable the clinician to decide optimal treatment strategies for patients with carotid stenosis.

    Full Text Available Hemorrhagic transformation (HT may occur as a part of the natural history of acute ischemic stroke, with incidence between 13-43% in computer-tomography (CT studies. Detection of HT in a patient with ischemic stroke is important in establishing treatment in the acute phase in assessing prognosis and in taking therapeutical decisions for secondary stroke prevention. There were controversies regarding optimal treatment in acute ischemic stroke with HT, especially if the patient needs further anticoagulant or antiplatelet treatment. Rehabilitation treatment needs to be continued for post-stroke patients who developed HT, because HT does not decrease rehabilitation outcome. We present rehabilitation treatment and prognosis in a case of hemorrhagic transformation after an embolic ischemic stroke treated with anticoagulants, which required reinitiation of anticoagulant treatment.

    Riks-Stroke, the Swedish Stroke Register, is the world's longest-running national stroke quality register (established in 1994) and includes all 76 hospitals in Sweden admitting acute stroke patients. The development and maintenance of this sustainable national register is described. Riks-Stroke includes information on the quality of care during the acute phase, rehabilitation and secondary prevention of stroke, as well as data on community support. Riks-Stroke is unique among stroke quality registers in that patients are followed during the first year after stroke. The data collected describe processes, and medical and patient-reported outcome measurements. The register embraces most of the dimensions of health-care quality (evidence-based, safe, provided in time, distributed fairly and patient oriented). Annually, approximately 25,000 patients are included. In 2009, approximately 320,000 patients had been accumulated (mean age 76-years). The register is estimated to cover 82% of all stroke patients treated in Swedish hospitals. Among critical issues when building a national stroke quality register, the delicate balance between simplicity and comprehensiveness is emphasised. Future developments include direct transfer of data from digital medical records to Riks-Stroke and comprehensive strategies to use the information collected to rapidly implement new evidence-based techniques and to eliminate outdated methods in stroke care. It is possible to establish a sustainable quality register for stroke at the national level covering all hospitals admitting acute stroke patients. Riks-Stroke is fulfilling its main goals to support continuous quality improvement of Swedish stroke services and serve as an instrument for following up national stroke guidelines. © 2010 The Authors.

    Atrial fibrillation (AF) is a major healthcare concern, being associated with an estimated five-fold risk of ischaemic stroke. In patients with AF, anticoagulants reduce stroke risk to a greater extent than acetylsalicylic acid (ASA) or dual antiplatelet therapy (DAPT) with ASA plus clopidogrel. Non-vitamin K antagonist oral anticoagulants (NOACs) are now a widely-accepted therapeutic option for stroke prevention in non-valvular AF (NVAF). There are particular patient types with NVAF for whom treatment challenges remain, owing to sparse clinical data, their high-risk nature or a need to harmonise anticoagulant and antiplatelet regimens if co-administered. This article focuses on three randomised controlled trials (RCTs) that are investigating the utility of rivaroxaban, a direct, oral, factor Xa inhibitor, in additional areas of stroke prevention where data for anticoagulants are lacking: oPen-label, randomized, controlled, multicentre study explorIng twO treatmeNt stratEgiEs of Rivaroxaban and a dose-adjusted oral vitamin K antagonist treatment (PIONEER AF-PCI); New Approach riVaroxoban Inhibition of factor Xa in a Global trial vs Aspirin to prevenT Embolism in Embolic Stroke of Undetermined Source (NAVIGATE ESUS); and Global study comparing a rivAroxaban-based antithrombotic strategy to an antipLatelet-based strategy after transcatheter aortIc vaLve rEplacement to Optimize clinical outcomes (GALILEO). Data from these studies present collaborative efforts to build upon existing registrational Phase III data for rivaroxaban, driving the need for effective and safe treatment of a wider range of patients for stroke prevention.

    Individuals with stroke fall frequently, and no exercise intervention has been shown to prevent falls post stroke. Perturbation-based balance training (PBT), which involves practicing reactions to instability, shows promise for preventing falls in older adults and individuals with Parkinson's disease. This study aimed to determine if PBT during inpatient stroke rehabilitation can prevent falls after discharge into the community. Individuals with subacute stroke completed PBT as part of routine inpatient rehabilitation (n = 31). Participants reported falls experienced in daily life for up to 6 months post discharge. Fall rates were compared to a matched historical control group (HIS) who did not complete PBT during inpatient rehabilitation. Five of 31 PBT participants, compared to 15 of 31 HIS participants, reported at least 1 fall. PBT participants reported 10 falls (.84 falls per person per year) whereas HIS participants reported 31 falls (2.0 falls per person per year). When controlled for follow-up duration and motor impairment, fall rates were lower in the PBT group than the HIS group (rate ratio: .36 [.15, .79]; P = .016). These findings suggest that PBT is promising for reducing falls post stroke. While this was not a randomized controlled trial, this study may provide sufficient evidence for implementing PBT in stroke rehabilitation practice. Copyright © 2017 National Stroke Association.

    2010-12-01

    Full Text Available Abstract Background Despite lack of outward signs, most individuals after non-disabling stroke (NDS and transient ischemic attack (TIA have significant cardiovascular and cerebrovascular disease and are at high risk of a major stroke, hospitalization for other vascular events, or death. Most have multiple modifiable risk factors (e.g., hypertension, physical inactivity, hyperlipidaemia, diabetes, tobacco consumption, psychological stress. In addition, accelerated rates of depression, cognitive decline, and poor quality of sleep have been reported following TIA, which correlate with poor functional outcomes and reduced quality of life. Thus, NSD and TIA are important warning signs that should not be overlooked. The challenge is not unlike that facing other 'silent' conditions - to identify a model of care that is effective in changing people's current behaviors in order to avert further morbidity. Methods/Design A single blind, randomized controlled trial will be conducted at two sites to compare the effectiveness of a program of rehabilitative exercise and education versus usual care in modifying vascular risk factors in adults after NDS/TIA. 250 adults within 90 days of being diagnosed with NDS/TIA will be randomly allocated to a 12-week program of exercise and education (PREVENT or to an outpatient clinic assessment and discussion of secondary prevention recommendations with return clinic visits as indicated (USUAL CARE. Primary outcome measures will include blood pressure, waist circumference, 12-hour fasting lipid profile, and 12-hour fasting glucose/hemoglobin A1c. Secondary measures will include exercise capacity, walking endurance, physical activity, cognitive function, depression, goal attainment and health-related quality of life. Outcome assessment will be conducted at baseline, post-intervention, and 6- and 12-month follow-ups. Direct health care costs incurred over one year by PREVENT versus USUAL CARE participants will also be

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

    We sought to compare the benefit of percutaneous closure to that of medical therapy alone for the secondary prevention of embolism in patients with patent foramen ovale (PFO) and otherwise unexplained ischemic stroke, in a propensity scored study. Between 2000 and 2012, we selected consecutive first-ever ischemic stroke patients aged 18 to 45 years with PFO and no other cause of brain ischemia, as part of the IPSYS registry (Italian Project on Stroke in Young Adults), who underwent either percutaneous PFO closure or medical therapy for comparative analysis. Primary end point was a composite of ischemic stroke, transient ischemic attack, or peripheral embolism. Secondary end point was brain ischemia. Five hundred and twenty-one patients qualified for the analysis. The primary end point occurred in 15 patients treated with percutaneous PFO closure (7.3%) versus 33 patients medically treated (10.5%; hazard ratio, 0.72; 95% confidence interval, 0.39-1.32; P=0.285). The rates of the secondary end point brain ischemia were also similar in the 2 treatment groups (6.3% in the PFO closure group versus 10.2% in the medically treated group; hazard ratio, 0.64; 95% confidence interval, 0.33-1.21; P=0.168). Closure provided a benefit in patients aged 18 to 36 years (hazard ratio, 0.19; 95% confidence interval, 0.04-0.81; P=0.026) and in those with a substantial right-to-left shunt size (hazard ratio, 0.19; 95% confidence interval, 0.05-0.68; P=0.011). PFO closure seems as effective as medical therapy for secondary prevention of cryptogenic ischemic stroke. Whether device treatment might be more effective in selected cases, such as in patients younger than 37 years and in those with a substantial right-to-left shunt size, deserves further investigation. © 2016 American Heart Association, Inc.

    Evidence-based therapeutic options for stroke continue to emerge based on results from well-designed clinical studies. Ischemic stroke far exceeds hemorrhagic stroke in terms of prevalence and incidence, both in the USA and worldwide. The public health effect of reducing death and disability related to ischemic stroke justifies the resources that have been invested in identifying safe and effective treatments. The emergence of novel oral anticoagulants for ischemic stroke prevention in atrial fibrillation has introduced complexity to clinical decision making for patients with this common cardiac arrhythmia. Some accepted ischemic stroke preventative strategies, such as carotid revascularization for asymptomatic carotid stenosis, require reassessment, given advances in risk factor management, antithrombotic therapy, and surgical techniques. Intra-arterial therapy, particularly with stent retrievers after intravenous tissue plasminogen activator, has recently been demonstrated to improve functional outcomes and will require investment in system-based care models to ensure that effective treatments are received by patients in a timely fashion. The purpose of this review is to describe recent advances in medical and surgical approaches to ischemic stroke prevention and acute treatment. Results from recently published clinical trials will be highlighted along with ongoing clinical trials addressing key questions in ischemic stroke management and prevention where equipoise remains.

    Stroke is a major health problem in Latin American and Caribbean countries. In this paper, we review the epidemiology, aetiology, and management of stroke in the region based on a systematic search of articles published in Spanish, Portuguese, and English. Stroke mortality is higher than in developed countries but rates are declining. Population-based studies show variations in incidence of strokes: lower rates of ischaemic stroke and similar rates of intracranial haemorrhages, compared with other regions. A significant proportion of strokes in these populations can be attributed to a few preventable risk factors. Some countries have published national clinical guidelines, although much needs to be done in the organisation of care and rehabilitation. Even though the burden of stroke is high, there is a paucity of information for implementing evidence-based management. The Global Stroke Initiative, the WHO STEPS Stroke surveillance, and WHO-PREMISE projects provide opportunities for surveillance at institutional and community levels.

    The use of medication plays an important role in secondary stroke prevention and treatment of post-stroke comorbidities. The Collaborative Evaluation of Rehabilitation in Stroke across Europe (CERISE) was set up to investigate the inpatient stroke rehabilitation process in four centres, each in a different European country: Belgium, Germany, United Kingdom and Switzerland. Patients' medication use 5 years post-stroke was compared between countries. Focus was put on cerebrovascular secondary prevention, including (a) adequate antithrombotic treatment, (b) treatment of cardiovascular comorbidities and diabetes, and (c) the use of lipid-lowering drugs; as well as on the treatment of stroke-related disorders such as depression, anxiety and pain. Medication data were available for 247 patients. Data about depression and anxiety were available for 233. There were no significant differences between the four centres in antithrombotic treatment and in the treatment of cardiovascular comorbidities and diabetes. However, significantly more patients from the UK were treated with lipid-lowering drugs compared to Belgian patients. Significant differences were also observed between the centres in the prevalence and treatment of depression. More Belgian patients suffered from depression compared to German patients and significantly more Belgian patients took antidepressants than patients in Germany. This was in contrast to the prevalence and treatment of anxiety and pain, for which no significant differences between the centres were seen. Related to pain treatment, it was observed that almost 40% of all patients suffering from pain, used no specific medication. Copyright © 2016 Elsevier B.V. All rights reserved.

    Oral anticoagulation is recommended for stroke prevention in intermediate/high stroke risk atrial fibrillation (AF) patients. The objective of this study was to demonstrate the usefulness of analytic software tools for descriptive analyses of disease management in atrial AF; a secondary objective is to demonstrate patterns of potential anticoagulant undertreatment in AF. Retrospective data analyses were performed using the Anticoagulant Quality Improvement Analyzer (AQuIA), a software tool designed to analyze health plan data. Two-year data from five databases were analyzed: IMS LifeLink (IMS), MarketScan Commercial (MarketScanCommercial), MarketScan Medicare Supplemental (MarketScanMedicare), Clinformatics™ DataMart, a product of OptumInsight Life Sciences (Optum), and a Medicaid Database (Medicaid). Included patients were ≥ 18 years old with a new or existing diagnosis of AF. The first observed AF diagnosis constituted the index date, with patient outcomes assessed over a one year period. Key study measures included stroke risk level, anticoagulant use, and frequency of International Normalized Ratio (INR) monitoring. High stroke risk (CHADS2 ≥ 2 points) was estimated in 54% (IMS), 22% (MarketScanCommercial), 64% (MarketscanMedicare), 42% (Optum) and 62% (Medicaid) of the total eligible population. Overall, 35%, 29%, 38%, 39% and 16% of all AF patients received an anticoagulant medication in IMS, MarketScanCommercial, MarketScanMedicare, Optum and Medicaid, respectively. Among patients at high risk for stroke, 19% to 51% received any anticoagulant. The AQuIA provided a consistent platform for analysis across multiple AF populations with varying baseline characteristics. Analyzer results show that many high-risk AF patients in selected commercial, Medicare-eligible, and Medicaid populations do not receive appropriate thromboprophylaxis, as recommended by treatment guidelines.

    The majority of evidence on the safety and efficacy of oral anticoagulation for stroke prevention amongst patients with atrial fibrillation is derived from those without significant valvular heart disease. This article will review current knowledge, areas of uncertainty and controversy, and ongoing research on oral anticoagulation for stroke prevention amongst patients with valvular heart disease. The rates of stroke, systemic embolism, and major bleeding were similar for patients with and without significant native valvular disease when treated with direct oral anticoagulants (DOACs) or vitamin K antagonists. There are very limited prospective data on the safety and efficacy of DOAC use for patients with bioprosthetic valves or rheumatic mitral stenosis. Atrial fibrillation patients with concomitant valvulopathies constitute a group with high thromboembolic risk and should be treated with oral anticoagulation. There is good supportive evidence that DOAC is well tolerated and effective in preventing thromboembolism amongst patients with native valvular disease. Further research is underway to better define the risks and benefits of DOAC use among patients with bioprosthetic valves or rheumatic mitral stenosis in preventing thromboembolic events. Until then, vitamin K antagonists remain the oral anticoagulant of choice for these patient subsets.

    The recurrent Heubner's artery is the distal part of the medial striate artery. Occlusion of the recurrent artery of Heubner, classically contralateral hemiparesis with fasciobrachiocrural predominance, is attributed to the occlusion of the recurrent artery of Heubner and is widely known as a stroke syndrome in adults. However, isolated occlusion of the deep perforating arteries following mild head trauma also occurs extremely rarely in childhood. Here we report the case of an 11-year-old boy with pure motor stroke. The brain MRI showed an acute ischemia in the recurrent artery of Heubner supply area following mild head trauma. His fasciobrachial hemiparesis and dysarthria were thought to be secondary to the stretching of deep perforating arteries leading to occlusion of the recurrent artery of Heubner. Post-traumatic pure motor ischemic stroke can be secondary to stretching of the deep perforating arteries especially in childhood.

    Full Text Available Abstract Background Stroke is the most common disabling neurological condition in adults. Falls and poor mobility are major contributors to stroke-related disability. Falls are more frequent and more likely to result in injury among stroke survivors than among the general older population. Currently there is good evidence that exercise can enhance mobility after stroke, yet ongoing exercise programs for general community-based stroke survivors are not routinely available. This randomised controlled trial will investigate whether exercise can reduce fall rates and increase mobility and physical activity levels in stroke survivors. Methods and design Three hundred and fifty community dwelling stroke survivors will be recruited. Participants will have no medical contradictions to exercise and be cognitively and physically able to complete the assessments and exercise program. After the completion of the pre-test assessment, participants will be randomly allocated to one of two intervention groups. Both intervention groups will participate in weekly group-based exercises and a home program for twelve months. In the lower limb intervention group, individualised programs of weight-bearing balance and strengthening exercises will be prescribed. The upper limb/cognition group will receive exercises aimed at management and improvement of function of the affected upper limb and cognition carried out in the seated position. The primary outcome measures will be falls (measured with 12 month calendars and mobility. Secondary outcome measures will be risk of falling, physical activity levels, community participation, quality of life, health service utilisation, upper limb function and cognition. Discussion This study aims to establish and evaluate community-based sustainable exercise programs for stroke survivors. We will determine the effects of the exercise programs in preventing falls and enhancing mobility among people following stroke. This program, if

The importance of lowering blood pressure for reducing the risk of stroke is well established. However, not all the benefits of antihypertensive treatments in stroke can be accounted for by reductions in BP and there may be differences between antihypertensive classes as to which provides optimal protection. Dihydropyridine calcium channel blockers, such as amlodipine, and angiotensin receptor blockers, such as valsartan, represent the two antihypertensive drug classes with the strongest supportive data for the prevention of stroke. Therefore, when combination therapy is required, a combination of these two antihypertensive classes represents a logical approach.Keywords: stroke, angiotensin, calcium channel, cerebrovascular, hypertension, blood pressure

    Even though stroke is the third, not the first, most common cause of disability-adjusted life years in developed countries, it is one of the most expensive to treat. Part of the expense is due to secondary problems in the post-stroke period including: cognition, memory, attention span, pain, sensation loss, psychological issues, and problems with mobility and balance. Research has identified that exercise has both positive physical and psychosocial effects for post-stroke patients. Therefore, this scientific statement provides an overview on exercise rehabilitation for post-stroke patients.We will use systematic literature reviews, clinical and epidemiology reports, published morbidity and mortality studies, clinical and public health guidelines, patient files, and authoritative statements to support this overview.Evidence clearly supports the use of various kinds of exercise training (e.g., aerobic, strength, flexibility, neuromuscular, and traditional Chinese exercise) for stroke survivors. Aerobic exercise, the main form of cardiac rehabilitation, may play an important role in improving aerobic fitness, cardiovascular fitness, cognitive abilities, walking speed and endurance, balance, quality of life, mobility, and other health outcomes among stroke patients. Strength exercise, included in national stroke guidelines and recommended for general health promotion for stroke survivors, can lead to improvements in functionality, psychosocial aspects, and quality of life for post-stroke patients. Flexibility exercises can relieve muscle spasticity problems, improve motor function, range of motion, and prevent contractures. Stretching exercises can also prevent joint contractures, muscle shortening, decrease spasticity, reduce joint stiffness and improve a post-stroke patient's overall function. Neuromuscular exercises can improve activities of daily living (ADL) through coordination and balance activities. Traditional Chinese exercises are used to improve walking and

    According to the Australian Bureau of Statistics, stroke is the second leading cause of death in Australia. The clinical Guidelines for stroke management published by the National Stroke Foundation provide a series of evidence based recommendations to assist clinicians in the management of stroke patients. Appropriate management of patients admitted to stroke units reduces death and disability by 20 %. Moreover, a multidisciplinary team approach also improves patient outcomes. To retrospectively review the pharmacological management of ischaemic stroke patients in a metropolitan Australian hospital, and to compare adherence with the guidelines for stroke management with the national stroke foundation data with and without pharmacist intervention. A retrospective audit of medical records was undertaken of all patients admitted to a large teaching hospital with the diagnosis of stroke or cerebral infarction from January 2013 to May 2013. A total of 124 patients were included in the study. Most patients were discharged on appropriate pharmacological intervention for the prevention of secondary stroke: antihypertensive agents (71 %), lipid lowering agents (67 %) and antithrombotic (85 %) medications. The majority of the cohort was discharged on the appropriate evidence based medications for the management of secondary stroke. Further improvement may be achieved by pharmacist intervening as part of a multidisciplinary team.

    Stroke in young adults is uncommon and rarely described. Moyamoya disease is one of the leading causes of stroke in young adults. We aimed to study the prognostic factors for stroke recurrences and functional outcomes in young stroke patients with moyamoya disease after revascularization. We reviewed 696 consecutive patients with moyamoya disease admitted to our hospital from 2009-2015 and identified patients aged 18-45 years with first-ever stroke. Follow-up was conducted via face-to-face or structured telephone interviews. Outcome measures were recurrent stroke events and unfavorable functional outcomes (modified Rankin Scale >2). We included 121 young patients with moyamoya disease suffering from stroke (initial presentation age, 35.4 ± 7.5 years). All patients underwent revascularization after the acute phase of initial stroke events as the secondary prevention for recurrences. During follow-up (median, 40 months), 9 patients (7.4%) experienced recurrent strokes and 8 of them (6.6%) suffered unfavorable functional outcomes. In the multivariate analysis, diabetes was an independent predictor for stroke recurrences (hazard ratio 6.76; 95% confidence interval 1.30-35.11; P = 0.02) and was significantly associated with unfavorable functional outcomes (odds ratio 7.87; 95% confidence interval 1.42-38.74; P = 0.01). We identified diabetes as an independent risk factor for recurrent strokes and unfavorable functional outcomes after revascularization in young stroke patients with moyamoya disease.

    Full Text Available Abstract Background Survivors of transient ischemic attack (TIA or stroke are at high risk for recurrent vascular events and aggressive treatment of vascular risk factors can reduce this risk. However, vascular risk factors, especially hypertension and high cholesterol, are not managed optimally even in those patients seen in specialized clinics. This gap between the evidence for secondary prevention of stroke and the clinical reality leads to suboptimal patient outcomes. In this study, we will be testing a pharmacist case manager for delivery of stroke prevention services. We hypothesize this new structure will improve processes of care which in turn should lead to improved outcomes. Methods We will conduct a prospective, randomized, controlled open-label with blinded ascertainment of outcomes (PROBE trial. Treatment allocation will be concealed from the study personnel, and all outcomes will be collected in an independent and blinded manner by observers who have not been involved in the patient's clinical care or trial participation and who are masked to baseline measurements. Patients will be randomized to control or a pharmacist case manager treating vascular risk factors to guideline-recommended target levels. Eligible patients will include all adult patients seen at stroke prevention clinics in Edmonton, Alberta after an ischemic stroke or TIA who have uncontrolled hypertension (defined as systolic blood pressure (BP > 140 mm Hg or dyslipidemia (fasting LDL-cholesterol > 2.00 mmol/L and who are not cognitively impaired or institutionalized. The primary outcome will be the proportion of subjects who attain 'optimal BP and lipid control'(defined as systolic BP Conclusions Nearly one-quarter of those who survive a TIA or minor stroke suffer another vascular event within a year. If our intervention improves the provision of secondary prevention therapies in these patients, the clinical (and financial implications will be enormous.

    With the increasing incidences of cerebrovascular disease, as well as the morbidity and mortality associated with it, it is of no surprise that there have been much global governmental interest in the primary prevention of this disorder; or at least in the secondary and tertiary prevention and rehabilitation of individuals who have suffered disabilities arising from a recent cerebrovascular attack. Developers and clinicians have not considered one of the key areas in Stroke prevention and management, which is that of secondary prevention, and in particular that of tapping onto smartphone technologies for stroke rehabilitation. There has been much interest in the development of devices for rehabilitation of stroke patients instead. One of the concerns with regards to conventional bio and mechanical sensors are the costs involved in development, as well as the costs involved when stroke survivors and their caregivers are required to purchase the devices for monitoring and rehabilitation. In view of the current limitations, the S3 Rehab application, which makes use of the smartphone build in sensors, has been conceptualized and has been developed for the two major platforms (Apple and Android platforms). The authors believe that by tapping onto these sensors and by programming a smartphone application that is specifically catered for rehabilitation, it would keep costs minimal for researchers, patients and caregivers. Whilst there is a growing interest in wearable devices and sensors, it is important for developers and researchers to be cognizant that certain interventions, such as rehabilitation could still be done through a smartphone device, instead of investing in new research and development. There are various untapped potential in the smartphone that researchers and developers need to be cognizant of.

    There is growing recognition that patients may respond differently to therapy and that the average treatment effect from a clinical trial may not apply equally to all candidates for a therapy. To determine whether, among patients with an ischemic stroke or transient ischemic attack and insulin resistance, those at higher risk for future stroke or myocardial infarction (MI) derive more benefit from the insulin-sensitizing drug pioglitazone hydrochloride compared with patients at lower risk. A secondary analysis was conducted of the Insulin Resistance Intervention After Stroke trial, a double-blind, placebo-controlled trial of pioglitazone for secondary prevention. Patients were enrolled from 179 research sites in 7 countries from February 7, 2005, to January 15, 2013, and were followed up for a mean of 4.1 years through the study's end on July 28, 2015. Eligible participants had a qualifying ischemic stroke or transient ischemic attack within 180 days of entry and insulin resistance without type 1 or type 2 diabetes. Pioglitazone or matching placebo. A Cox proportional hazards regression model was created using baseline features to stratify patients above or below the median risk for stroke or MI within 5 years. Within each stratum, the efficacy of pioglitazone for preventing stroke or MI was calculated. Safety outcomes were death, heart failure, weight gain, and bone fracture. Among 3876 participants (1338 women and 2538 men; mean [SD] age, 63 [11] years), the 5-year risk for stroke or MI was 6.0% in the pioglitazone group among patients at lower baseline risk compared with 7.9% in the placebo group (absolute risk difference, -1.9% [95% CI, -4.4% to 0.6%]). Among patients at higher risk, the risk was 14.7% in the pioglitazone group vs 19.6% for placebo (absolute risk difference, -4.9% [95% CI, -8.6% to 1.2%]). Hazard ratios were similar for patients below or above the median risk (0.77 vs 0.75; P = .92). Pioglitazone increased weight less among patients at

    Full Text Available Abstract Background More than 60% of new strokes each year are "mild" in severity and this proportion is expected to rise in the years to come. Within our current health care system those with "mild" stroke are typically discharged home within days, without further referral to health or rehabilitation services other than advice to see their family physician. Those with mild stroke often have limited access to support from health professionals with stroke-specific knowledge who would typically provide critical information on topics such as secondary stroke prevention, community reintegration, medication counselling and problem solving with regard to specific concerns that arise. Isolation and lack of knowledge may lead to a worsening of health problems including stroke recurrence and unnecessary and costly health care utilization. The purpose of this study is to assess the effectiveness, for individuals who experience a first "mild" stroke, of a sustainable, low cost, multimodal support intervention (comprising information, education and telephone support - "WE CALL" compared to a passive intervention (providing the name and phone number of a resource person available if they feel the need to - "YOU CALL", on two primary outcomes: unplanned-use of health services for negative events and quality of life. Method/Design We will recruit 384 adults who meet inclusion criteria for a first mild stroke across six Canadian sites. Baseline measures will be taken within the first month after stroke onset. Participants will be stratified according to comorbidity level and randomised to one of two groups: YOU CALL or WE CALL. Both interventions will be offered over a six months period. Primary outcomes include unplanned use of heath services for negative event (frequency calendar and quality of life (EQ-5D and Quality of Life Index. Secondary outcomes include participation level (LIFE-H, depression (Beck Depression Inventory II and use of health services for

    Patients with atrial fibrillation are at a greater risk of stroke and therefore the main goal for treatment of patients with atrial fibrillation is to prevent stroke from occurring. There are a number of different stroke prevention treatments available to include warfarin and novel oral anticoagulants. Previous network meta-analyses of novel oral anticoagulants for stroke prevention in atrial fibrillation acknowledge the limitation of heterogeneity across the included trials but have not explored the impact of potentially important treatment modifying covariates. To explore potentially important treatment modifying covariates using network meta-regression analyses for stroke prevention in atrial fibrillation. We performed a network meta-analysis for the outcome of ischaemic stroke and conducted an exploratory regression analysis considering potentially important treatment modifying covariates. These covariates included the proportion of patients with a previous stroke, proportion of males, mean age, the duration of study follow-up and the patients underlying risk of ischaemic stroke. None of the covariates explored impacted relative treatment effects relative to placebo. Notably, the exploration of 'study follow-up' as a covariate supported the assumption that difference in trial durations is unimportant in this indication despite the variation across trials in the network. This study is limited by the quantity of data available. Further investigation is warranted, and, as justifying further trials may be difficult, it would be desirable to obtain individual patient level data (IPD) to facilitate an effort to relate treatment effects to IPD covariates in order to investigate heterogeneity. Observational data could also be examined to establish if there are potential trends elsewhere. The approach and methods presented have potentially wide applications within any indication as to highlight the potential benefit of extending decision problems to include additional

    Growth hormone replacement therapy has benefits for patients with hypopituitarism. The safety profile in regard to tumor recurrence or progression, development of secondary malignancies, or cerebrovascular stroke is still an area of debate. A comprehensive search of multiple databases-MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus was conducted through August 2015. Eligible studies that evaluated long-term adverse events in adult patients with hypopituitarism treated with growth hormone replacement therapy and reported development of pituitary tumor recurrence or progression, secondary malignancies, or cerebrovascular stroke were selected following a predefined protocol. Reviewers, independently and in duplicate, extracted data and assessed the risk of bias. Random-effects meta-analysis was used to pool relative risks and 95 % confidence intervals. We included 15 studies (published 1995-2015) that reported on 46,148 patients. Compared to non-replacement, growth hormone replacement therapy in adults with hypopituitarism was not associated with statistically significant change in pituitary tumor progression or recurrence (relative risk, 0.77; 95 % confidence interval, 0.53-1.13) or development of secondary malignancy (relative risk, 0.99; 95 % confidence interval, 0.70-1.39). In two retrospective studies, there was higher risk of stroke in patients who did not receive replacement (relative risk, 2.07; 95 % confidence interval, 1.51-2.83). The quality of evidence is low due to study limitations and imprecision. This systematic review and meta-analysis supports the overall safety of growth hormone therapeutic use in adults with hypopituitarism with no clear evidence of increased risk of pituitary tumor recurrence, malignancy, or stroke.

    Severity of acute vascular illness may have changed in the last decades due to improvements in primary and secondary prevention. Population-based data on the severity of acute ischemic cerebrovascular disease are sparse. We aimed to examine incidence, characteristics and severity of acute ischemic cerebrovascular disease in a well-defined population. All patients admitted with transient ischemic attack (TIA) or acute ischemic stroke from March 1, 2007, to February 29, 2008, with residence in the Aarhus area, were included. Incidence rates and characteristics of TIA and ischemic stroke were compared. TIA accounted for 30%, TIA and minor stroke combined for 65% of all acute ischemic cerebrovascular events. Age-adjusted incidence rates of TIA and ischemic stroke were 72.2/100,000 and 129.5/100,000 person-years, respectively. TIA patients were younger than stroke patients (66.3 vs. 72.7 years; p TIA and stroke patients share many characteristics; however, TIA patients are younger and have fewer manifestations of atherosclerotic diseases, indicating a high potential for secondary prevention.

    The Prevention of VTE after Acute Ischemic Stroke with LMWH (PREVAIL) study demonstrated that enoxaparin was superior to unfractionated heparin (UFH) in preventing venous thromboembolism in patients with ischemic stroke and was associated with a small but statistically significant increase in extracranial hemorrhage rates. In this PREVAIL subanalysis, we evaluate the long-term neurological outcomes associated with the use of enoxaparin compared with UFH. We also determine predictors of stroke progression. Acute ischemic stroke patients aged >or=18 years, who could not walk unassisted, were randomized to receive enoxaparin (40 mg once daily) or UFH (5000 U every 12 hours) for 10 days. Patients were stratified according to baseline stroke severity using the National Institutes of Health Stroke Scale score. End points for this analysis included stroke progression (>or=4-point increase in National Institutes of Health Stroke Scale score), neurological outcomes up to 3 months postrandomization (assessed using National Institutes of Health Stroke Scale score and modified Rankin Scale score), and incidence of intracranial hemorrhage. Stroke progression occurred in 45 of 877 (5.1%) patients in the enoxaparin group and 42 of 872 (4.8%) of those receiving UFH. Similar improvements in National Institutes of Health Stroke Scale and modified Rankin Scale scores were observed in both groups over the 90-day follow-up period. Incidence of intracranial hemorrhage was comparable between groups (20 of 877 [2.3%] and 22 of 872 [2.5%] in enoxaparin and UFH groups, respectively). Baseline National Institutes of Health Stroke Scale score, hyperlipidemia, and Hispanic ethnicity were independent predictors of stroke progression. The clinical benefits associated with use of enoxaparin for venous thromboembolism prophylaxis in patients with acute ischemic stroke are not associated with poorer long-term neurological outcomes or increased rates of symptomatic intracranial hemorrhage compared

    African Americans are at heightened risk of first stroke, and regular exercise can reduce stroke risk. Benefits and barriers to exercise subscales from 2 instruments were combined to create the Exercise Benefits and Barriers for Stroke Prevention (EBBSP) scale. Reliability and validity of the EBBSP scale were examined in a nonrandom sample of 66 African Americans who were primarily female, average age 43.3 ± 9.4 years, and high school graduates. Both subscales had adequate internal consistency reliability. Factor analysis revealed two factors for each subscale. More benefits and fewer perceived barriers were significantly related to current exercise and future intentions to exercise. The EBBSP scale may be useful in research focused on understanding, predicting, and promoting exercise for stroke prevention in adults.

    Full Text Available OBJECTIVES: The effects of AT1 receptor blocker, telmisartan, and the ACE inhibitor, ramipril, were tested head-to head and in combination on stroke prevention in hypertensive rats and on potential neuroprotection in acute cerebral ischemia in normotensive rats. METHODS: Prevention study: Stroke-prone spontaneously hypertensive rats (SHR-SP were subjected to high salt and randomly assigned to 4 groups: (1 untreated (NaCl, n = 24, (2 telmisartan (T; n = 27, (3 ramipril (R; n = 27 and (4 telmisartan + ramipril (T+R; n = 26. Drug doses were selected to keep blood pressure (BP at 150 mmHg in all groups. Neurological signs and stroke incidence at 50% mortality of untreated SHR-SP were investigated. Intervention study: Normotensive Wistar rats were treated s.c. 5 days prior to middle cerebral artery occlusion (MCAO for 90 min with reperfusion. Groups (n = 10 each: (1 sham, (2 vehicle (V; 0.9% NaCl, (3 T (0.5 mg/kg once daily, (4 R (0.01 mg/kg twice daily, (5 R (0.1 mg/kg twice daily or (6 T (0.5 mg/kg once daily plus R (0.01 mg/kg twice daily. Twenty-four and 48 h after MCAO, neurological outcome (NO was determined. Forty-eight h after MCAO, infarct volume by MRI, neuronal survival, inflammation factors and neurotrophin receptor (TrkB were analysed. RESULTS: Stroke incidence was reduced, survival was prolonged and neurological outcome was improved in all treated SHR-SP with no differences between treated groups. In the acute intervention study, T and T+R, but not R alone, improved NO, reduced infarct volume, inflammation (TNFα, and induced TrkB receptor and neuronal survival in comparison to V. CONCLUSIONS: T, R or T+R had similar beneficial effects on stroke incidence and NO in hypertensive rats, confirming BP reduction as determinant factor in stroke prevention. In contrast, T and T+R provided superior neuroprotection in comparison to R alone in normotensive rats with induced cerebral ischemia.

    Cardioembolism in paroxysmal atrial fibrillation (pxAF) is a frequent cause of ischemic stroke. Sensitive detection of pxAF after stroke is crucial for adequate secondary stroke prevention; the optimal diagnostic modality to detect pxAF on stroke units is unknown. We compared 24-hour Holter electrocardiography (ECG) with continuous stroke unit ECG monitoring (CEM) for pxAF detection. Patients with acute ischemic stroke or transient ischemic attack were prospectively enrolled. After a 12-channel ECG on admission, all patients received 24-hour Holter ECG and CEM. Additionally, ECG monitoring data underwent automated analysis using dedicated software to identify pxAF. Patients with a history of atrial fibrillation or with atrial fibrillation on the admission ECG were excluded. Four hundred ninety-six patients (median age, 69 years; 61.5% male) fulfilled all inclusion criteria (ischemic stroke: 80.4%; transient ischemic attack: 19.6%). Median stroke unit stay lasted 88.8 hours (interquartile range, 65.0-122.0). ECG data for automated CEM analysis were available for a median time of 64.0 hours (43.0-89.8). Paroxysmal AF was documented in 41 of 496 patients (8.3%). Of these, Holter detected pxAF in 34.1%; CEM in 65.9%; and automated CEM in 92.7%. CEM and automated CEM detected significantly more patients with pxAF than Holter (Pstroke on stroke units compared with 24-hour Holter ECG. The comparative usefulness of prolonged or repetitive Holter ECG recordings requires further evaluation.

    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.

    PURPOSE: Treatment with antiplatelet drugs is a key element of secondary stroke prevention. We investigated long-term antiplatelet drug use in stroke patients with a focus on non-persistence. METHODS: Population-based prescription register data were used to determine antiplatelet drug use...... the dosage of a previous prescription had run out, or within 180 days after discharge. Cox regression was used to identify risk factors for non-persistence. RESULTS: The cohort comprised 503 patients with ischaemic stroke discharged in 1999-2001.

    OBJECTIVES To review the available published literature to assess whether evidence supports a beneficial role for coordinated transition of care services for the postacute care of patients hospitalized with first or recurrent stroke or myocardial infarction (MI). This review was framed around five areas of investigation: (1) key components of transition of care services, (2) evidence for improvement in functional outcomes, morbidity, mortality, and quality of life, (3) associated risks or potential harms, (4) evidence for improvement in systems of care, and (5) evidence that benefits and harms vary by patient-based or system-based characteristics. DATA SOURCES MEDLINE(®), CINAHL(®), Cochrane Database of Systematic Reviews, and Embase(®). REVIEW METHODS We included studies published in English from 2000 to 2011 that specified postacute hospitalization transition of care services as well as prevention of recurrent stroke or MI. RESULTS A total of 62 articles representing 44 studies were included for data abstraction. Transition of care interventions were grouped into four categories: (1) hospital -initiated support for discharge was the initial stage in the transition of care process, (2) patient and family education interventions were started during hospitalization but were continued at the community level, (3) community-based models of support followed hospital discharge, and (4) chronic disease management models of care assumed the responsibility for long-term care. Early supported discharge after stroke was associated with reduced total hospital length of stay without adverse effects on functional recovery, and specialty care after MI was associated with reduced mortality. Because of several methodological shortcomings, most studies did not consistently demonstrate that any specific intervention resulted in improved patient-or system -based outcomes. Some studies included more than one intervention, which made it difficult to determine the effect of individual

    2016-05-01

    Full Text Available Stroke is predominantly a senescent disease, yet most preclinical studies investigate treatment in young animals. We recently demonstrated that short-duration hypothermia-treatment completely prevented the dramatic intracranial pressure (ICP rise seen post-stroke in young rats. Here, our aim was to investigate whether a similar ICP rise occurs in aged rats and to determine whether short-duration hypothermia is an effective treatment in aged animals. Experimental Middle Cerebral Artery occlusion (MCAo - 3 hour occlusion was performed on male Wistar rats aged 19-20 months. At one hour after stroke-onset, rats were randomized to 2.5 hours hypothermia-treatment (32.5 °C or normothermia (37 °C. ICP was monitored at baseline, for 3.5 hours post-occlusion, and at 24 hours post-stroke. Infarct and edema volumes were calculated from histology. Baseline pre-stroke ICP was 11.2 ± 3.3 mmHg across all animals. Twenty-four hours post-stroke, ICP was significantly higher in normothermic animals compared to hypothermia-treated animals (27.4 ± 18.2 mmHg vs. 8.0 ± 5.0 mmHg, p = 0.03. Infarct and edema volumes were not significantly different between groups. These data demonstrate ICP may also increase 24 hours post-stroke in aged rats, and that short-duration hypothermia treatment has a profound and sustained preventative effect. These findings may have important implications for the use of hypothermia in clinical trials of aged stroke patients.

    Background and Purpose Stroke survivors are at risk of developing co-morbidities that further reduce their quality of life. The purpose of this study was to determine the risk of developing a secondary health problem after stroke. Methods We performed a case-control analysis using six biennial interview waves (1998 to 2008) of the Health and Retirement Study. We compared 631 non-institutionalized individuals who had suffered a single stroke to 631 controls matched for age, gender and interview-wave. We studied sleep problems, urinary incontinence (UI), motor impairment, falls and memory deficits among the two groups. Results Stroke survivors frequently developed new or worsened motor impairment (33%), sleep problems (up to 33%), falls (30%), UI (19%), and memory deficits (9%). As compared with controls, the risk of developing a secondary health problem was highest for memory deficits (OR: 2.45, 95%CI: 1.34-4.46), followed by UI (OR: 1.86, 95%CI: 1.31-2.66), motor impairment (OR: 1.61, 95%CI: 1.16-2.24), falls (OR: 1.5, 95%CI: 1.12-2.0) and sleep disturbances (OR: 1.49, 95%CI: 1.09-2.03). In contrast, stroke survivors were not more likely to injure themselves during a fall (OR: 1.14, 95%CI: 0.72-1.79). After adjusting for cardiovascular risk factors, social status, psychiatric symptoms and pain, the risks of falling or developing sleep problems were not different from the control subjects. Conclusions The risk of developing a secondary health problem that can impact daily life is markedly increased after stroke. A better understanding of frequencies and risks for secondary health problems after stroke are necessary for designing better preventive and rehabilitation strategies. PMID:21597018

    Full Text Available The purpose of the study was to comparatively analyze the rate of post-stroke depression and cognitive impairments in escitalopram (cipralex-treated and untreated (control patients. Emotional and affective cognitive symptoms, neurological deficit, and day-to-day activity were evaluated over time 1, 3, and 6 months after treatment. The results of the study indicated that escitalopram used to prevent depression in the acute phase of stroke provided a good effect. This drug caused a prompter recovery of cognitive impairments and reduced the pace of development of neurodegenerative disorders underlying the post-stroke 2D (depression and dementia syndrome. The study group was recorded to have more favorable functional outcomes of stroke and patient mobility indicators associated with lower disability rates.

    Full Text Available Sickle Cell Disease(SCD is one of the most common hemoglobinopathies in the world which causes stroke. The management of stroke depends on the manifestations and the age of the patient. Especially in childhood, anatomic and physiological abnormalities of CNS may be a predisposing factors. Stroke mostly affects the distal segments of the Internal Carotid Artery, but also middle and anterior segments of the cerebral arteries are involved. The most important predisposing factors are the arterial malformations, stenosis and obstructions in cranial arteries, generally involving Internal Carotid Artery, frequently Proximal Middle Cerebral or Anterior Cerebral Arteries. After infarcts at brain vessels, most frequent clinical findings are hemiparesis or hemiplegia, impaired speech, focal seizures, gait disturbances. Risk factors for predisposing stroke are prior transient ischemia, baseline Hb decrease, acute chest sydrome within previous two weeks, systolic blood pressure rises, leucocyte increases. The patient with silent stroke or transient ischemic attacks may be asymptomatic or without neurological symptoms. Neuroimaging abnormalities may be seen without significant clinical findings in children with SCD. We talk about silent stroke if there are neuroradiological abnormalities without clinical findings. Children with silent strokes are more prone to new strokes. If there is a significant stroke a ischemic stroke often present with focal neurological signs and symptoms. If patient is asymptomatic or have suspected stroke, first step may be performance of Transcranial Doppler Ultrasonography (TCD. Children with time-averaged mean velocity (TAMV, measured in Middle Carotid Artery or in distal internal carotid Artery abnormally elevated, defined as TAMV≥200cm/sec, have sixfold increase for stroke than those with normal TAMV≤170cm/sec. For these patients under the risk of stroke, chronic blood transfusion is recommended for prevention of primary

    There is some evidence to suggest that the standard of acute medical care provided to patients with cerebrovascular disease is a major determinant of the eventual outcome. Consequently, the Royal College of Physicians (RCP) of London issues periodic guidelines to assist healthcare providers in the management of patients presenting with stroke. An audit of the acute management of stroke in two hospitals belonging to the same health care trust in the UK. Retrospective review of 98 randomly selected case-notes of patients managed for cerebrovascular disease in two acute hospitals in the UK between April and June 2004. The pertinent guidelines of RCP (London) are highlighted while audit targets were set at 70%. 84% of patients presenting with cerebrovascular disease had a stroke rather than a TIA, anterior circulation strokes were commonest. All patients with stroke were admitted while those with TIAs were discharged on the same day but most patients with TIA were not followed up by Stroke specialists. Most CT-imaging of the head was done after 24 hours delaying the commencement of anti-platelets for patients with ischaemic stroke or neurosurgical referral for haemorrhagic stroke. Furthermore, there was a low rate of referral for carotid ultrasound in patients with anterior circulation strokes. Anti-platelets and statins were commenced for most patients with ischaemic stroke while diabetes was well controlled in most of them. However, ACE-inhibitors and diuretics such as indapamide were under-utilized for secondary prevention in such patients. Warfarin anti-coagulation was underutilized in patients with ischaemic stroke who had underlying chronic atrial fibrillation. While there was significant multi-disciplinary team input, dysphagia and physiotherapy assessments were delayed. Similarly, occupational therapy input and psychological assesment were omitted from the care of most patients. Hospital service provision for the management of cerebrovascular disease needs to

    The risk of stroke is greatest among adults who have experienced a previous stroke, transient ischemic attack, or myocardial infarction. Physical activity may reduce the secondary risk of stroke through mediating effects on blood pressure, vasoconstriction, and circulating lipid concentrations; however, little is known about the prevalence of physical activity and sedentary behavior among stroke survivors in the United States. Using data from the National Health and Nutrition Examination Survey (NHANES), we describe self-reported and objectively measured physical activity and sedentary behavior among adults with a self-reported history of stroke. We also contrast physical activity among stroke survivors with that of adults without stroke (unexposed) to illustrate expected behavior in the absence of disease. Fewer participants with stroke met weekly physical activity guidelines as outlined in the 2008 Physical Activity Guidelines for Americans when compared with unexposed participants (17.9% vs 25.0%) according to self-reported data. In addition, participants with stroke reported less moderate (46.1% vs 54.7%) and vigorous (9.1% vs 19.6%) leisure activity compared with unexposed participants. As measured by accelerometer, time since diagnosis was inversely associated with physical activity engagement, and participants with stroke recorded more daily hours of sedentary behavior compared with unexposed participants (10.1 hours vs 8.9 hours). Findings from this study provide a basis for future work seeking to measure the impact of physical activity on the secondary prevention of stroke by characterizing the prevalence of physical activity and sedentary behavior among stroke survivors in the United States.

    Few population-based studies have assessed lipid adherence to international guidelines for primary and secondary prevention in stroke/transient ischaemic attack (TIA) patients. This study aims to evaluate adherence to lipid-lowering therapy (LLT) guidelines amongst patients with ischaemic stroke/TIA. Using hot and cold pursuit methods from multiple hospital/community sources, all stroke and TIA cases in North Dublin City were prospectively ascertained over a 1-year period. Adherence to National Cholesterol Education Programme (NCEP) III guidelines, before and after index ischaemic stroke/TIA, was assessed. Amongst 616 patients (428 ischaemic stroke, 188 TIA), total cholesterol was measured following the qualifying event in 76.5% (471/616) and low-density lipoprotein (LDL) in 60.1% (370/616). At initial stroke/TIA presentation, 54.1% (200/370) met NCEP III LDL goals. Compliance was associated with prior stroke (odds ratio [OR] 2.19, p = 0.02), diabetes (OR 1.91, p = 0.04), hypertension (OR 1.57, p = 0.03), atrial fibrillation (OR 1.78, p = 0.01), pre-event LLT (OR 2.85, p TIA onset, 32.7% (195/596) was on LLT. Nonetheless, LDL exceeded individual NCEP goal in 29.2% (56/192); 21.6% (53/245) warranting LLT was not on treatment prior to stroke/TIA onset. After index stroke/TIA, 75.9% (422/556) was on LLT; 15.3% (30/196) meeting NCEP III criteria was not prescribed a statin as recommended. By 2 years, actuarial survival was 72.8% and 11.9% (59/497) experienced stroke recurrence. No association was observed between initial post-event target adherence and 2-year outcomes. In this population-based study, LLT recommended by international guidelines was under-used, before and after index stroke/TIA. Strategies to improve adherence are needed.

    The natural history and therapeutic interventions for secondary prevention after a cerebrovascular event in patients with patent foramen ovale (PFO) are not yet established. This study aims to assess the safety and efficacy of percutaneous PFO closure in a population of patients with ischemic cerebrovascular disease of unknown etiology. This prospective observational study included patients with a history of cryptogenic transient ischemic attack (TIA) or stroke who underwent percutaneous PFO closure. The effectiveness of the device for the secondary prevention of TIA or stroke was assessed by comparing observed events in the sample with expected events for this clinical setting. The sample included 193 cases of percutaneous PFO closure (age 46.4 ± 13.1 years, 62.2% female) with a mean follow-up of 4.3 ± 2.2 years, corresponding to a total exposure to ischemic events of 542 patient-years. The high-risk characteristics of the PFO were assessed prior to device implantation. There were seven primary endpoint events during follow-up (1.3 per 100 patient-years), corresponding to a relative risk reduction of 68.2% in recurrent TIA or stroke compared to medical therapy alone. The procedure was associated with a low rate of device- or intervention-related complications (1.5%). In this long-term registry, percutaneous PFO closure was shown to be a safe and effective therapy for the secondary prevention of cryptogenic stroke or TIA.

    Stroke is a rare condition in childhood with an estimated incidence of between 1.3-13/100.000 patients. Clinical manifestation and risk factors for paediatric stroke are different from those of adults. The uncommon incidence, age-associated difference and plethora of clinical symptoms make the diagnosis of such strokes extremely difficult and often delayed. The history and clinical examination should point to diseases or predisposing factors. Neuroimaging (DWI MR) is the golden standard for diagnosis of paediatric stroke and other investigations can be considered according to the clinical condition. Despite advances in paediatric stroke research and clinical care, questions remain unanswered regarding acute treatment, secondary prevention and rehabilitation. The treatment recommendations are mainly extrapolated from studies on adult populations. In the review authors summarized the clinical characteristics and diagnostic steps for stroke in children/adolescents based on the most recent international guidelines and practical directions for recognising and managing the child/adolescent with stroke in paediatric emergency. In the two case reports, we describe the clinical course in both stroke patients.

    We discuss the frequency of stroke misdiagnosis and identify subgroups of stroke at high risk for specific diagnostic errors. In addition, we review common reasons for misdiagnosis and propose solutions to decrease error. According to a recent report by the National Academy of Medicine, most people in the USA are likely to experience a diagnostic error during their lifetimes. Nearly half of such errors result in serious disability and death. Stroke misdiagnosis is a major health care concern, with initial misdiagnosis estimated to occur in 9% of all stroke patients in the emergency setting. Under- or missed diagnosis (false negative) of stroke can result in adverse patient outcomes due to the preclusion of acute treatments and failure to initiate secondary prevention strategies. On the other hand, the overdiagnosis of stroke can result in inappropriate treatment, delayed identification of actual underlying disease, and increased health care costs. Young patients, women, minorities, and patients presenting with non-specific, transient, or posterior circulation stroke symptoms are at increased risk of misdiagnosis. Strategies to decrease diagnostic error in stroke have largely focused on early stroke detection via bedside examination strategies and a clinical decision rules. Targeted interventions to improve the diagnostic accuracy of stroke diagnosis among high-risk groups as well as symptom-specific clinical decision supports are needed. There are a number of open questions in the study of stroke misdiagnosis. To improve patient outcomes, existing strategies to improve stroke diagnostic accuracy should be more broadly adopted and novel interventions devised and tested to reduce diagnostic errors.

    Abstract Background: Previous study indicated that high-dose statin treatment might increase the risk of hemorrhagic stroke and adverse reactions. We aim to compare the efficacy and safety of intensive-dose and standard-dose statin treatment for preventing stroke in high-risk patients. Methods: A thorough search was performed of multiple databases for publications from 1990 to June 2015. We selected the randomized clinical trials comparing standard-dose statin with placebo and intensive-dose statin with standard-dose statin or placebo for the prevention of stroke events in patients. Duplicate independent data extraction and bias assessments were performed. Data were pooled using a fixed-effects model or a random-effects model if significant heterogeneity was present. Results: For the all stroke incidences, intensive-dose statin treatment compared with placebo treatment and standard-dose statin treatment compared with placebo treatment showed a significant 21% reduction in relative risk (RR) (RR 0.79, 95% confidence interval (CI) [0.71, 0.87], P statin treatment compared with standard dose or placebo was effective reducing fatal stroke (RR 0.61, 95% CI [0.39, 0.96], P = 0.03) and the RR was 1.01 (95% CI [0.85, 1.20], P = 0.90) in standard-dose statin treatment compared with placebo. Conclusion: The results of this meta-analysis suggest that intensive-dose statin treatment might be more favorable for reducing the incidences of all strokes than standard-dose statin treatment, especially for patients older than 65 years in reducing the incidences of all stroke incidences.

    Breast cancer is the most common cancer among women and is the second cancer frequently occurring worldwide of newly-diagnosed cancers. There is much evidence showing the influence of life style and environmental factors on the development of mammary gland cancer (high-fat diet, alcohol consumption, lack of physical exercise), the elimination of which (primary prevention) may contribute to a decrease in morbidity and mortality. Secondary prevention, comprising diagnostic tests (e.g. mammography, ultrasonography, magnetic resonance imaging, breast self-examination, as well as modern and more precise imaging methods) help the early detection of tumours or lesions predisposing to tumours. The aim of this study paper is to review current knowledge and reports regarding primary and secondary prevention of breast cancer. It is estimated that nearly 70% of malign tumours are caused by environmental factors, whereas in breast cancer this percentage reaches 90-95%. There are national programmes established in many countries to fight cancer, where both types of prevention are stressed as serving to decrease morbidity and mortality due to cancers. Cancer prevention is currently playing a key role in the fight against the disease. Behaviour modification, as well as greater awareness among women regarding breast cancer, may significantly contribute towards reducing the incidence of this cancer. Another important aspect is the number of women undergoing diagnostic tests, which still remains at an unsatisfactory level.

    The diagnosis of hypertension, as recommended by most guidelines, is determined by systolic blood pressure ≥140 mm Hg and/or diastolic blood pressure ≥90 mm Hg. A threshold-based definition of hypertension, however, ignores sex and age, pathophysiology, and disparities in patient-specific conditions. Moreover, the harmful effects of hypertension-induced target organ damage cannot be ignored. Although the principle of individualization for hypertension management is recommended, especially for stroke prevention, how to practice it in a clinical setting has not been clearly elaborated. Therefore, we put forward a proposal for individualized hypertension management incorporating target organ damage, the main harmful effect of hypertension. We propose that hypertension should be diagnosed when an individual's blood pressure exceeds some difference from their own baseline in young adulthood, accompanied by any hypertension-induced target organ damage, confirmed by various detection methods. Application of this proposal to stroke prevention will hopefully strengthen the principle of individualized hypertension management. ©2015 Wiley Periodicals, Inc.

    Lipids have important functions in the human body, but high serum cholesterol level is an important risk factor for cardiovascular and cerebrovascular diseases. Prevention of stroke includes modifying risk factors, like dyslipidemias. Based on this theory, we examined in practice the possible role of a public care neurology and stroke department with a large patient turnover in vascular risk screening with regard to the diagnosis of hyperlipidemia. We reviewed all the medical records (irrespective of disease group;) of patients hospitalized in 2007 at Department of Neurclogy and Stroke Center of Szent János Hospital of the Municipality of the City of Budapest. Patients included in the study were classified into three groups: (1) those admitted with acute stroke; (2) those with a history of acute stroke, but without evidence of a novel cerebrovascular event; (3) no history and evidence of cerebrovascular disease during hospitalization. Our data show that 17.6% of patients was diagnosed with hyperlipidemia during hospital care, and another 18.5% was known to have elevated cholesterol levels. Altogether, 36.1% of the 1438 patients evaluated had hyper ipidemia. Known hypercholesterolemia was 18.4% in patierts admitted for acute stroke, 26.9% in patients formerly (but not currently) treated for cerebrovascular disease, and 13.6% in the third group. Newly diagnosed elevated cholesterol levels had highest rate (22.6%) in former stroke patierts (currently treated for other diseases); 20.4% in patients with acute stroke, and 13.2% in the third group. In the first two groups, the number of patients newly diagnosed with elevated serum cholesterol almost equaled to those with already known hypercholesterolemia. Based on our data, neurology departments have an important role in diagnosing hyperlipidemia and vascular prevention.

    Rationale Optimal secondary prevention of embolic stroke of undetermined source is not established. The current standard in these patients is acetylsalicylic acid, despite high prevalence of yet undetected paroxysmal atrial fibrillation. Aim The ATTICUS randomized trial is designed to determine whether the factor Xa inhibitor apixaban administered within 7 days after embolic stroke of undetermined source, is superior to acetylsalicylic acid for prevention of new ischemic lesions documented by brain magnetic resonance imaging within 12 months after index stroke. Design Prospective, randomized, blinded, parallel-group, open-label, German multicenter phase III trial in approximately 500 patients with embolic stroke of undetermined source. A key inclusion criterion is the presence or the planned implantation of an insertable cardiac monitor. Patients are 1:1 randomized to apixaban or acetylsalicylic acid and treated for a 12-month period. It is an event-driven trial aiming for core-lab adjudicated primary outcome events. Study outcomes The primary outcome is the occurrence of at least one new ischemic lesion identified by axial T2-weighted FLAIR magnetic resonance imaging and/or axial DWI magnetic resonance imaging at 12 months when compared with the baseline magnetic resonance imaging. Key secondary outcomes are the combination of recurrent ischemic strokes, hemorrhagic strokes, systemic embolism; combination of MACE including recurrent stroke, myocardial infarction, and cardiovascular death and combination of major and clinically relevant non-major bleeding defined according to ISTH, and change of cognitive function and quality of life (EQ-5D, Stroke Impact Scale). Discussion Embolic stroke of undetermined source is caused by embolic disease and associated with a high risk of recurrent ischemic strokes and clinically silent cerebral ischemic lesions. ATTICUS will investigate the impact of atrial fibrillation detected by insertable cardiac monitor and the effects of

    Identifying the etiology of ischemic stroke is essential to acute management and secondary prevention. The value of liver function indicators in differentiating stroke subtypes remains to be evaluated. A total of 1333 acute ischemic stroke patients were included. Liver function indicators collected within 24 hours from stroke onset, including alanine aminotransferase, aspartate aminotransferase (AST), alkaline phosphatase, gamma-glutamyl transpeptidase (GGT), and bilirubin (BILI), were collapsed into quartiles (Q) and also dichotomized by Q1. Multivariate regression analysis was conducted to identify the independent association between liver function indicators and cardioembolic stroke (SCE). Area under the curve (AUC) of receiver operating characteristic analysis was conducted, and sensitivity (Sen), specificity (Spe), positive prospective value (PPV), and negative prospective value (NPV) were determined to evaluate the predictive value of liver function indicators for SCE. AST, GGT, and BILI were associated with SCE. After adjustment, only AST was related to SCE independently. The incidence of SCE in the Q1 of AST, GGT, and BILI, particularly in the Q1 of AST, was quite low. The ability of AST, GGT, and BILI to identify SCE was poor, with low AUC, Sen, and PPV. The value of AST, GGT, and BILI in eliminating SCE from stroke subtypes was good, with high Spe and moderate NPV, and was enhanced after combining each liver function indicator. Results of present study demonstrated that AST, GGT, and BILI, particularly AST, had a potential to eliminate SCE from stroke subtypes, and the ability of eliminating SCE would be strengthened after combining each liver function indicator together.

    Background: Controversy persists regarding the management of patients with cryptogenic stroke and patent foramen ovale (PFO). We performed a meta-analysis of randomized controlled trials comparing PFO closure with medical therapy. Methods and Results: A prospective protocol was developed and registered using the following data sources: PubMed, Cochrane Register of Controlled Trials, conference proceedings, and Internet-based resources of clinical trials. Primary analyses were performed using the intention-to-treat method. Three randomized trials comparing percutaneous PFO closure vs. medical therapy for secondary prevention of embolic neurological events formed the data set. Baseline characteristics were similar. During long-term follow-up, the pooled incidence of the primary endpoint (composite of stroke, death, or fatal stroke) was 3.4% in the PFO closure arm and 4.8% in the medical therapy group [risk-reduction (RR) 0.7 (0.48–1.06); p = 0.09]. The incidence of recurrent neurological events (secondary endpoint) was 1.7% for PFO closure and 2.7% for medical therapy [RR 0.66 (0.35–1.24), p = 0.19]. There was no difference in terms of death or adverse events between the two groups. Conclusions: While this meta-analysis of randomized clinical trials demonstrated no statistical significance in comparison to medical therapy, there was a trend towards overall improvement in outcomes in the PFO closure group

    Donghua Mi

    Full Text Available OBJECTIVES: To analyze the effect of metabolic syndrome (MetS on prognosis of ischemic stroke secondary to intracranial stenosis in Chinese patients. METHODS: A prospective cohort of 701 patients with ischemic stroke, caused by intracranial stenosis, were followed at 3-month intervals for 1 year to monitor development of recurrent stroke or death. Imaging was performed using magnetic resonance angiography. MetS was defined using International Diabetes Federation (IDF criteria. RESULTS: MetS was identified in 26.0% of the cohort of stroke patients. Patients with MetS were more likely to be female, nonsmokers, and more likely to have a prior history of diabetes mellitus, high blood glucose and a family history of stroke than patients without MetS. During 1-year follow-up, patients with MetS had a non-significantly higher rate of stroke recurrence (7.1% than patients without MetS (3.9%; P = 0.07. There was no difference in mortality (3.3% versus 3.5%, respectively. Multivariate Cox proportional hazards analysis (adjusting for gender, BMI, smoking, diabetes, and LDL-C identified an association between that 1-year stroke recurrence and the presence of MetS (hazard ratio 2.30; 95% CI: 1.01-5.22 and large waist circumference (hazard ratio: 2.39; 95% CI: 1.05-5.42. However, multivariable analysis adjusting for the individual components of MetS found no significant associations between MetS and stroke recurrence. There were no associations between these parameters and mortality. CONCLUSIONS: Chinese patients with symptomatic intracranial atherosclerosis who have MetS, are at higher risk of recurrent stroke than those without MetS. However, MetS was not predictive of stroke recurrence beyond its individual components and one-year mortality.

    Full Text Available Background. Stroke is a major healthcare problem with serious long-term disability and is one of the leading causes of death in the world. Prevention of stroke is considered an important strategy. Methods. Seven electronic databases were searched. Results. 36 eligible studies with a total of 2393 participants were identified. Primary outcome measures, TCC exercise combined with other intervention had a significant effect on decreasing the incidence of nonfatal stroke (n=185, RR = 0.11, 95% CI 0.01 to 0.85, P=0.03 and CCD (n=125, RR = 0.33, 95% CI 0.11 to 0.96, P=0.04. For the risk factors of stroke, pooled analysis demonstrated that TCC exercise was associated with lower body weight, BMI, FBG level, and decreasing SBP, DBP, plasma TC, and LDL-C level regardless of the intervention period less than half a year or more than one year and significantly raised HDL-C level in comparison to nonintervention. Compared with other treatments, TCC intervention on the basis of the same other treatments in patients with chronic disease also showed the beneficial effect on lowering blood pressure. Conclusion. The present systematic review indicates that TCC exercise is beneficially associated with the primary prevention of stroke in middle-aged and elderly adults by inversing the high risk factors of stroke.

  3. Shared decision-making in stroke: an evolving approach to improved patient care.

    Shared decision-making (SDM) occurs when patients, families and clinicians consider patients' values and preferences alongside the best medical evidence and partner to make the best decision for a given patient in a specific scenario. SDM is increasingly promoted within Western contexts and is also being explored outside such settings, including in China. SDM and tools to promote SDM can improve patients' knowledge/understanding, participation in the decision-making process, satisfaction and trust in the healthcare team. SDM has also proposed long-term benefits to patients, clinicians, organisations and healthcare systems. To successfully perform SDM, clinicians must know their patients' values and goals and the evidence underlying different diagnostic and treatment options. This is relevant for decisions throughout stroke care, from thrombolysis to goals of care, diagnostic assessments, rehabilitation strategies, and secondary stroke prevention. Various physician, patient, family, cultural and system barriers to SDM exist. Strategies to overcome these barriers and facilitate SDM include clinician motivation, patient participation, adequate time and tools to support the process, such as decision aids. Although research about SDM in stroke care is lacking, decision aids are available for select decisions, such as anticoagulation for stroke prevention in atrial fibrillation. Future research is needed regarding both cultural aspects of successful SDM and application of SDM to stroke-specific contexts.

    Although many stroke patients are young or middle-aged, risk factor profiles in these age groups are poorly understood. The Stroke in Young Fabry Patients (sifap1) study prospectively recruited a large multinational European cohort of patients with cerebrovascular events aged 18 to 55 years to establish their prevalence of Fabry disease. In a secondary analysis of patients with ischemic stroke or transient ischemic attack, we studied age- and sex-specific prevalences of various risk factors. Among 4467 patients (median age, 47 years; interquartile range, 40-51), the most frequent well-documented and modifiable risk factors were smoking (55.5%), physical inactivity (48.2%), arterial hypertension (46.6%), dyslipidemia (34.9%), and obesity (22.3%). Modifiable less well-documented or potentially modifiable risk factors like high-risk alcohol consumption (33.0%) and short sleep duration (20.6%) were more frequent in men, and migraine (26.5%) was more frequent in women. Women were more often physically inactive, most pronouncedly at ages young patients with acute ischemic cerebrovascular events, modifiable risk factors were highly prevalent, particularly in men and older patients. These data emphasize the need for vigorous primary and secondary prevention measures already in young populations targeting modifiable lifestyle vascular risk factors.

    This article discusses the ethical, practical, and moral issues surrounding secondary prevention efforts of child sexual abuse from a professional and practice-based perspective. Transcripts of a semistructured consultation event with n = 15 international experts on the secondary prevention of child sexual abuse were analysed using thematic qualitative analysis. The research identified four main critical areas linked to secondary prevention efforts, including, the psychology of self-reporting and disclosure; the interaction with and within existing legal, social, and professional frameworks; the scale and type of an appropriate response; and potential hurdles (i.e., within media, public, politics). The article outlines these areas, highlighting participant perspectives on risk-enhancing and mitigating factors for each domain.

    Stroke is a major cause of disability and family disruption and carries a high risk of recurrence. Lifestyle factors that increase the risk of recurrence include smoking, unhealthy diet, excessive alcohol consumption and physical inactivity. Guidelines recommend that secondary prevention interventions, which include the active provision of lifestyle information, should be initiated in hospital, and continued by community-based healthcare professionals (HCPs) following discharge. However, stroke patients report receiving little/no lifestyle information.There is a limited evidence-base to guide the development and delivery of effective secondary prevention lifestyle interventions in the stroke field. This study, which was underpinned by the Theory of Planned Behaviour, sought to explore the beliefs and perceptions of patients and family members regarding the provision of lifestyle information following stroke. We also explored the influence of beliefs and attitudes on behaviour. We believe that an understanding of these issues is required to inform the content and delivery of effective secondary prevention lifestyle interventions. We used purposive sampling to recruit participants through voluntary sector organizations (29 patients, including 7 with aphasia; 20 family members). Using focus group methods, data were collected in four regions of Scotland (8 group discussions) and were analysed thematically. Although many participants initially reported receiving no lifestyle information, further exploration revealed that most had received written information. However, it was often provided when people were not receptive, there was no verbal reinforcement, and family members were rarely involved, even when the patient had aphasia. Participants believed that information and advice regarding healthy lifestyle behaviour was often confusing and contradictory and that this influenced their behavioural intentions. Family members and peers exerted both positive and negative

    Cryptogenic strokes can be attributed to paradoxical emboli through patent foramen ovale (PFO). However, the effectiveness of PFO closure in preventing recurrent stroke is uncertain and the results of previous randomized clinical trials (RCTs) have been inconclusive. Hence, this study provides an updated meta-analysis of all RCTs comparing PFO closure with medical therapy for secondary prevention of cryptogenic stroke. All RCTs were identified by a comprehensive literature search of PubMed, Embase, the Cochrane Collaboration Central Register of Controlled Trials, Scopus, and Clinicaltrials.gov. The primary outcome was recurrent ischemic stroke and secondary outcomes were transient ischemic attack (TIA), all-cause mortality, new-onset atrial fibrillation (AF), serious adverse events, and major bleeding. 5 RCTs with 3440 participants were included in the present study (1829 patients underwent PFO closure and 1611 were treated medically). Pooled analysis showed a statistically significant reduction in the rate of recurrent stroke with PFO closure in comparison to medical therapy (OR 0.41; 95% CI 0.19-0.90; p = 0.03). However, there were no statistically significant reductions of recurrent TIAs (OR 0.77; 95% CI 0.51-1.14; p = 0.19) or all-cause mortality (OR 0.76; 95% CI 0.35-1.65; p = 0.48). The risk of developing new-onset AF was increased significantly with PFO closure (OR 4.74; 95% CI 2.33-9.61; p Patent foramen ovale closure in adults with recent cryptogenic stroke was associated with a lower rate of recurrent strokes in comparison with medical therapy alone.

    Full Text Available Background. There are few data on the mechanism of recurrent neurological events after transcatheter closure of patent foramen ovale (PFO in cryptogenic stroke or TIA. Methods. We retrospectively reviewed PFO closure procedures for the secondary prevention of cryptogenic stroke/TIA performed between 1999 and 2014 in Bologna, Italy. Results. Written questionnaires were completed by 402 patients. Mean follow-up was 7 ± 3 years. Stroke recurred in 3.2% (0.5/100 patients-year and TIA in 2.7% (0.4/100 patients-year. Ninety-two percent of recurrent strokes were not cryptogenic. Recurrent stroke was noncardioembolic in 69% of patients, AF related in 15% of patients, device related in 1 patient, and cryptogenic in 1 patient. AF was diagnosed after the procedure in 21 patients (5.2%. Multivariate Cox’s proportion hazard model identified age ≥ 55 years at the time of closure (OR 3.16, p=0.007 and RoPE score < 7 (OR 3.21, p=0.03 as predictors of recurrent neurological events. Conclusion. Recurrent neurological events after PFO closure are rare, usually noncryptogenic and associated with conventional vascular risk factors or AF related. Patients older than 55 years of age and those with a RoPE score < 7 are likely to get less benefit from PFO closure. After transcatheter PFO closure, lifelong strict vascular risk factor control is warranted.

    The National Prescribing Service (NPS) MedicineWise Stroke Prevention Program, which was implemented nationally in 2009-2010 in Australia, sought to improve antithrombotic prescribing in stroke prevention using dedicated interventions that target general practitioners. This study evaluated the impact of the NPS MedicineWise Stroke Prevention Program on antithrombotic prescribing and primary stroke hospitalizations. This population-based time series study used administrative health data linked to 45 and Up Study participants with a high risk of cardiovascular disease (CVD) to assess the possible impact of the NPS MedicineWise program on first-time aspirin prescriptions and primary stroke-related hospitalizations. Time series analysis showed that the NPS MedicineWise program was significantly associated with increased first-time prescribing of aspirin (P=0.03) and decreased hospitalizations for primary ischemic stroke (P=0.03) in the at-risk study population (n=90 023). First-time aspirin prescription was correlated with a reduction in the rate of hospitalization for primary stroke (P=0.02). Following intervention, the number of first-time aspirin prescriptions increased by 19.8% (95% confidence interval, 1.6-38.0), while the number of first-time stroke hospitalizations decreased by 17.3% (95% confidence interval, 1.8-30.0). Consistent with NPS MedicineWise program messages for the high-risk CVD population, the NPS MedicineWise Stroke Prevention Program (2009) was associated with increased initiation of aspirin and a reduced rate of hospitalization for primary stroke. The findings suggest that the provision of evidence-based multifaceted large-scale educational programs in primary care can be effective in changing prescriber behavior and positively impacting patient health outcomes. © 2016 The Authors and NPS MedicineWise.

Intima-medial thickness (IMT) is a well-known surrogate marker of atherosclerosis and has been used to predict stroke and cardiovascular events. However, the clinical significance of IMT and IMT change in stroke has not been investigated in well-designed studies. The PreventIon of CArdiovascular events in iSchemic Stroke patients with high risk of cerebral hemOrrhage-Intima-Media Thickness (PICASSO-IMT) sub-study is designed to investigate the effects of cilostazol, probucol, or both on IMT in patients with stroke. PICASSO-IMT is a prospective sub-study of the PICASSO study designed to measure IMT and plaque score at 1, 13, 25, 37, and 49 months after randomization. The primary outcome is the change in mean carotid IMT, which is defined as the mean of the far-wall IMTs of the right and left common carotid arteries, between baseline and 13 months after randomization. PICASSO-IMT will provide the largest IMT data set in a stroke population and will provide valuable information about the clinical significance of IMT in patients with ischemic stroke.

    Reducing the burden of stroke is a priority for the Veterans Affairs Health System, reflected by the creation of the Veterans Affairs Stroke Quality Enhancement Research Initiative. To inform the initiative's strategic planning, we estimated the relative population-level impact and efficiency of distinct approaches to improving stroke care in the US Veteran population to inform policy and practice. A System Dynamics stroke model of the Veteran population was constructed to evaluate the relative impact of 15 intervention scenarios including both broad and targeted primary and secondary prevention and acute care/rehabilitation on cumulative (20 years) outcomes including quality-adjusted life years (QALYs) gained, strokes prevented, stroke fatalities prevented, and the number-needed-to-treat per QALY gained. At the population level, a broad hypertension control effort yielded the largest increase in QALYs (35,517), followed by targeted prevention addressing hypertension and anticoagulation among Veterans with prior cardiovascular disease (27,856) and hypertension control among diabetics (23,100). Adjusting QALYs gained by the number of Veterans needed to treat, thrombolytic therapy with tissue-type plasminogen activator was most efficient, needing 3.1 Veterans to be treated per QALY gained. This was followed by rehabilitation (3.9) and targeted prevention addressing hypertension and anticoagulation among those with prior cardiovascular disease (5.1). Probabilistic sensitivity analysis showed that the ranking of interventions was robust to uncertainty in input parameter values. Prevention strategies tend to have larger population impacts, though interventions targeting specific high-risk groups tend to be more efficient in terms of number-needed-to-treat per QALY gained. © 2014 American Heart Association, Inc.

    Recurrent strokes are preventable through awareness and control of risk factors such as hypertension, and through lifestyle changes such as healthier diets, greater physical activity, and smoking cessation. However, vascular risk factor control is frequently poor among stroke survivors, particularly among socio-economically disadvantaged blacks, Latinos and other people of color. The Chronic Care Model (CCM) is an effective framework for multi-component interventions aimed at improving care processes and outcomes for individuals with chronic disease. In addition, community health workers (CHWs) have played an integral role in reducing health disparities; however, their effectiveness in reducing vascular risk among stroke survivors remains unknown. Our objectives are to develop, test, and assess the economic value of a CCM-based intervention using an Advanced Practice Clinician (APC)-CHW team to improve risk factor control after stroke in an under-resourced, racially/ethnically diverse population. In this single-blind randomized controlled trial, 516 adults (≥40 years) with an ischemic stroke, transient ischemic attack or intracerebral hemorrhage within the prior 90 days are being enrolled at five sites within the Los Angeles County safety-net setting and randomized 1:1 to intervention vs usual care. Participants are excluded if they do not speak English, Spanish, Cantonese, Mandarin, or Korean or if they are unable to consent. The intervention includes a minimum of three clinic visits in the healthcare setting, three home visits, and Chronic Disease Self-Management Program group workshops in community venues. The primary outcome is blood pressure (BP) control (systolic BP risk factors including lipids and hemoglobin A1c, (3) inflammation (C reactive protein [CRP]), (4) medication adherence, (5) lifestyle factors (smoking, diet, and physical activity), (6) estimated relative reduction in risk for recurrent stroke or myocardial infarction (MI), and (7) cost

  16. Cost-effectiveness of apixaban compared with warfarin for stroke prevention in atrial fibrillation.

    Full Text Available BACKGROUND: Apixaban was shown to be superior to adjusted-dose warfarin in preventing stroke or systemic embolism in patients with atrial fibrillation (AF and at least one additional risk factor for stroke, and associated with reduced rates of hemorrhage. We sought to determine the cost-effectiveness of using apixaban for stroke prevention. METHODS: Based on the results from the Apixaban Versus Warfarin in Patients with Atrial Fibrillation (ARISTOTLE trial and other published studies, we constructed a Markov model to evaluate the cost-effectiveness of apixaban versus warfarin from the Medicare perspective. The base-case analysis assumed a cohort of 65-year-old patients with a CHADS(2 score of 2.1 and no contraindication to oral anticoagulation. We utilized a 2-week cycle length and a lifetime time horizon. Outcome measures included costs in 2012 US$, quality-adjusted life-years (QALYs, life years saved and incremental cost-effectiveness ratios. RESULTS: Under base case conditions, quality adjusted life expectancy was 10.69 and 11.16 years for warfarin and apixaban, respectively. Total costs were $94,941 for warfarin and $86,007 for apixaban, demonstrating apixaban to be a dominant economic strategy. Upon one-way sensitivity analysis, these results were sensitive to variability in the drug cost of apixaban and various intracranial hemorrhage related variables. In Monte Carlo simulation, apixaban was a dominant strategy in 57% of 10,000 simulations and cost-effective in 98% at a willingness-to-pay threshold of $50,000 per QALY. CONCLUSIONS: In patients with AF and at least one additional risk factor for stroke and a baseline risk of ICH risk of about 0.8%, treatment with apixaban may be a cost-effective alternative to warfarin.

    To compare a specialized interprofessional team approach to community-based stroke rehabilitation with usual home care for stroke survivors using home care services. Randomized controlled trial of 101 community-living stroke survivors (stroke) using home care services. Subjects were randomized to intervention (n=52) or control (n=49) groups. The intervention was a 12-month specialized, evidence-based rehabilitation strategy involving an interprofessional team. The primary outcome was change in health-related quality of life and functioning (SF-36) from baseline to 12 months. Secondary outcomes were number of strokes during the 12-month follow-up, and changes in community reintegration (RNLI), perceived social support (PRQ85-Part 2), anxiety and depressive symptoms (Kessler-10), cognitive function (SPMSQ), and costs of use of health services from baseline to 12 months. A total of 82 subjects completed the 12-month follow-up. Compared with the usual care group, stroke survivors in the intervention group showed clinically important (although not statistically significant) greater improvements from baseline in mean SF-36 physical functioning score (5.87, 95% CI -3.98 to 15.7; p=0.24) and social functioning score (9.03, CI-7.50 to 25.6; p=0.28). The groups did not differ for any of the secondary effectiveness outcomes. There was a higher total per-person costs of use of health services in the intervention group compared to usual home care although the difference was not statistically significant (p=0.76). A 12-month specialized, interprofessional team is a feasible and acceptable approach to community-based stroke rehabilitation that produced greater improvements in quality of life compared to usual home care.

    The availability of 4 non-vitamin K oral anticoagulants (NOACs), that is, dabigatran, rivaroxaban, apixaban, and edoxaban, has changed the landscape of stroke prevention in patients with atrial fibrillation. This review article provides an overview of the 4 phase III studies that have compared these NOACs, examining major outcomes of efficacy and safety. A range of practical questions relating to the NOACs have emerged, including topics such as patient selection, treating patients with renal impairment, treating elderly patients, and combining anticoagulant therapy with antiplatelet drugs. We also address the interaction of various patient characteristics with the treatments and suggest the features can assist the physician in the choice of a particular NOAC for a particular patient(s).

    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.

    To determine the appropriateness of an online forum compared with face-to-face interviews as a source of data for qualitative research on adherence to secondary prevention medications after stroke. A comparison of attributes of two data sources, interviews and a forum, using realistic evaluation; a comparison of themes around adherence according to the Perceptions and Practicalities Approach (PAPA) framework. Interviews were conducted in UK GP practices in 2013 and 2014; online posts were written by UK stroke survivors and family members taking part in the online forum of the Stroke Association between 2004 and 2011. 42 interview participants: 28 stroke survivors (age range 61-92 years) and 14 caregivers (85% spouses). 84 online forum participants: 49 stroke survivors (age range 32-72 years) and 33 caregivers (60% sons/daughters). 10 attributes were identified within the two data sources and categorised under three domains (context, mechanisms and outcomes). Participants' characteristics of forum users were often missing. Most forum participants had experienced a stroke within the previous 12 months, while interviewees had done so 1-5 years previously.All interview themes could be matched with corresponding themes from the forum. The forum yielded three additional themes: influence of bad press on taking statins, criticisms of clinicians' prescribing practices and caregiver burden in assisting with medications and being advocates for survivors with healthcare professionals. An online forum is an appropriate source of data for qualitative research on patients' and caregivers' issues with adherence to secondary prevention stroke medications and may offer additional insights compared with interviews, which can be attributed to differences in the approach to data collection. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    There is no published literature regarding sub-Saharan health-care providers' understanding of stroke management patterns. Understanding current stroke management knowledge is important in formulating future education opportunities for providers to optimize patient outcomes. A cross-sectional survey of acute stroke diagnosis, hospital management, and secondary prevention questions was administered to health-care providers working in one large Kenyan acute referral hospital. Due to the prevalence of medical students (61.8%), an experienced-focused analysis contrasted students with more experienced providers. Providers (n=199) anonymously responded to the surveys. Among the acute diagnosis most respondents stated that stroke scales should always used (58.3% of respondents), 3h was the time period for alteplase (t-PA) (53.8% of respondents), and CT scan should be always be obtained prior to administration of anticoagulant therapy (61.3% of respondents). Neither VTE prophylaxis nor dysphagia/swallowing screening were considered to be done a majority of time. Secondary prevention results were variable. The respondent's level of clinical experience made the most difference in correctly answering the most appropriate IV Fluid to use in stroke patients (adjusted p=0.003) and the ideal initiation time for antithrombotic therapy (adjusted p=0.0017). Healthcare providers demonstrated a wide variability in their responses. Future efforts to improve stroke care in sub-Saharan Africa should include education and process improvement initiatives to focus on more specific aspects of stroke management based on the results from this survey.

    Full Text Available Gingival inflammation is the physiological response to poor oral hygiene. If gingivitis is not resolved the response will become an established lesion.We studied whether gingivitis associates with elevated risk for stroke. The hypothesis was based on the periodontitis-atherosclerosis paradigm.In our prospective cohort study from Sweden 1676 randomly selected subjects were followed up from 1985 to 2012. All subjects underwent clinical oral examination and answered a questionnaire assessing background variables such as socio-economic status and pack-years of smoking. Cases with stroke were recorded from the Center of Epidemiology, Swedish National Board of Health and Welfare, Sweden, and classified according to the WHO International Classification of Diseases. Unpaired t-test, chi-square tests, and multiple logistic regression analyses were used.Of the 1676 participants, 39 subjects (2.3% had been diagnosed with stroke. There were significant differences between the patients with stroke and subjects without in pack-years of smoking (p = 0.01, prevalence of gingival inflammation (GI (p = 0.03, and dental calculus (p = 0.017. In a multiple regression analysis the association between GI, confounders and stroke, GI showed odds ratio 2.20 (95% confidence interval 1.02-4.74 for stroke.Our present findings showed that gingival inflammation clearly associated with stroke in this 26-year cohort study. The results emphasize the role of oral health personnel in prevention.

    2018-02-19

    Worldwide, more than 7 million people experience acute myocardial infarction (AMI) every year (1), and although substantial reduction in mortality has been obtained in recent decades, one-year mortality rates are still in the range of 10%. Among patients who survive AMI, 20% suffer a second cardiovascular event in the first year and approximately 50% of major coronary events occur in those with a previous hospital discharge diagnosis of AMI (2). Despite the evidence that lifestyle changes and risk factors management strongly improve long-term prognosis, preventive care post-AMI remains sub-optimal. Cross-sectional data from the serially conducted EUROASPIRE surveys in patients with established ischemic heart disease (IHD) and people at high cardiovascular risk have demonstrated a high prevalence of unhealthy lifestyle, modifiable risk factors and inadequate use of drug therapies to achieve blood pressure and lipid goals (3). Secondary prevention programmes, defined as the level of preventive care focusing on early risk stratification, are highly recommended in all IHD patients, to restore quality of life, maintain or improve functional capacity and prevent recurrence.

    2016-01-01

    Postpartum heammorrhage (PPH), defined as blood loss greater than or equal to 500 ml within 24 hours after birth, is the leading cause of maternal deaths globally and in India. Misoprostol is an important option for PPH management in setting where oxytocin (the gold standard for PPH prevention and treatment) in not available or not feasible to use. For the substantial number of deliveries which take place at home or at lower level heatlh facilities in India, misoprostol pills can be adminstered to prevent PPH. The standard approach using misoprostol is to administer it prophylactically as primary prevention (600 mcg). An alternative strategy could be to administer misoprostol only to those who are at high risk of having PPH i.e. as secondary prevention. This study reports on the relative cost per person of a strategy involving primary versus secondary prevention of PPH using misoprostol. It is based on a randomized cluster trial that was conducted in Bijapur district in Karnataka, India between December 2011 and March 2014 among pregnant women to compare two community-level strategies for the prevention of PPH: primary and secondary. The analysis was conducted from the government perspective using an ingredient approach. The cluster trial showed that there were no significant differences in clinical outcomes between the two study arms. However, the results of the cost analysis show that there is a difference of INR 6 (US$ 0.1) per birth for implementing the strategies primary versus secondary prevention. In India where 14.9 million births take place at sub-centres and at home, this additional cost of INR 6 per birth translates to an additional cost of INR 94 (US$ 1.6) million to the government to implement the primary prevention compared to the secondary prevention strategy. As clinical outcomes did not differ significantly between the two arms in the trial, taking into account the difference in costs and potential issues with sustainability, secondary prevention

    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.

    Full Text Available BackgroundEvidence of a decline in the incidence of stroke has emerged from population-based studies. These have included retrospective and prospective cohorts. However, in Australia and other countries, government bodies and stroke foundations predict a rise in the prevalence of stroke that is anticipated to increase the burden of stroke across the entire domain of care. This increase in prevalence must be viewed as different from the decline in incidence being observed, a measure of new stroke cases. In Victoria, all public emergency department visits and public and private hospital admissions are reported to the Department of Health and Human Services and include demographic, diagnostic, and procedural/treatment information.MethodsWe obtained data from financial years 1997/1998 to 2007/2008 inclusive, for all cases with a primary stroke diagnosis (ICD-10-AM categories with associated data fields. Incident cases were established by using a 5-year clearance period.ResultsFrom 2003/2004 to 2007/2008 inclusive, there were 53,425 patients with a primary stroke or TIA diagnosis. The crude incident stroke rate for first ever stroke was 211 per 100,000 per year (95% CI 205–217 [females—205 per 100,000 per year (95% CI 196–214 and males—217 per 100,000 per year (95% CI 210–224]. The overall stroke rates were seen to significantly decline over the period [males (per 100,000 per year 227 in 2003/2004 to 202 in 2007/2008 (p = 0.0157 and females (per 100,000 per year 214 in 2003/2004 to 188 in 2007/2008 (p = 0.0482]. Ischemic stroke rates also appeared to decline; however, this change was not significant.ConclusionThese results demonstrate a significant decline in stroke incidence during the study period and may suggest evidence for effectiveness of primary and secondary prevention strategies in cerebrovascular risk factor management.

    To summarize the available evidence on the issues in health economics related to oral anticoagulation for stroke prevention in atrial fibrillation (AF) in the US. A literature review was performed using PubMed, EMBASE, Cochrane Library, and International Pharmaceutical Abstracts, as well as the websites of professional organizations. The search was conducted according to a prespecified protocol, limiting articles to those published in English from 2001 to October 2012 and focused on the economics associated with AF and AF-related stroke in the US. Data from 27 studies were extracted and included in the review. Strokes in patients with AF are more debilitating and have higher recurrence rates and mortality compared with strokes unrelated to AF. However, data describing the long-term cost of AF-related stroke and stroke subtypes remain limited. The costs of major gastrointestinal (GI) bleeding and intracranial bleeding related to warfarin are significant, whereas the costs of the more frequent minor GI bleeding are relatively low. Overall, the cost-effectiveness of warfarin versus aspirin or no treatment in patients with at least 1 risk factor for stroke is well established. Economic evaluations based on results from randomized controlled clinical trials generally found that new anticoagulants were a cost-effective alternative to warfarin for stroke prevention in AF. However, these cost-effectiveness results are highly sensitive to how well optimal international normalized ratio control is maintained (within target of 2.0-3.0) for warfarin and the time horizon used for analysis. Time in therapeutic range for warfarin in routine clinical practice was lower than in clinical trials, as shown by previous studies. This review identified several areas of uncertainty regarding the economic benefit of anticoagulants. The generalizability of cost-effectiveness results of anticoagulant therapy in AF based on clinical trial data must be confirmed by comparative effectiveness

    The 'European/Australasian stroke prevention in reversible ischaemia trial' (ESPRIT) aimed to determine whether oral anticoagulation of moderate intensity (target international normalised ratio (INR): 2.0-3.0) is more effective than acetylsalicylic acid in preventing future vascular events in patients with transient ischaemic attack (TIA) or minor stroke of arterial origin. International, multicentre randomised clinical trial. Patients were randomised within 6 months of TIA or minor stroke of arterial origin to oral anticoagulants (target INR: 2.0-3.0; n = 536) or acetylsalicylic acid (30-325 mg daily; n = 532). The primary endpoint was a composite of vascular death, non-fatal stroke, non-fatal myocardial infarction or major bleeding complications. In a post hoc analysis, the efficacy of anticoagulants was compared with that of the combination of acetylsalicylic acid and dipyridamole (200 mg twice daily), a third arm of ESPRIT. Treatment was unblinded, but auditing of endpoints was blinded. Data were analysed on an intent-to-treat basis. The comparison of anticoagulants and acetylsalicylic acid was stopped prematurely because the combination of acetylsalicylic acid and dipyridamole was found to be more effective than acetylsalicylic acid alone. The mean duration of follow-up was 4.6 years (SD: 2.2). The mean INR was 2.57 (SD: 0.86; nearly 70% of the time within target range). The primary endpoint occurred in 99 patients (19%) in the anticoagulation group and 98 patients (18%) in the acetylsalicylic acid group (hazard ratio: 1.02; 95% CI: 0.77-1.35). The hazard ratio was 0.73 (95% CI: 0.52-1.01) for ischaemic events and 2.56 (95% CI: 1.48-4.43) for major bleeding complications. The hazard ratio for the primary outcome event comparing anticoagulants with the combination of acetylsalicylic acid and dipyridamole was 1.31 (95% CI: 0.98-1.75). Oral anticoagulants (target INR: 2.0-3.0) were not more effective than acetylsalicylic acid in the secondary prevention of

  19. Netrin-1 Ameliorates Blood-Brain Barrier Impairment Secondary to Ischemic Stroke via the Activation of PI3K Pathway

    Full Text Available Secondary impairment of blood-brain barrier (BBB occurs in the remote thalamus after ischemic stroke. Netrin-1, an axonal guidance molecule, presents bifunctional effects on blood vessels through receptor-dependent pathways. This study investigates whether netrin-1 protects BBB against secondary injury. Netrin-1 (600 ng/d for 7 days was intracerebroventricularly infused 24 h after middle cerebral artery occlusion (MCAO in hypertensive rats. Neurological function was assessed 8 and 14 days after MCAO, and the permeability of BBB in the ipsilateral thalamus was detected. The viability of brain microvascular endothelial cells was determined after being disposed with netrin-1 (50 ng/mL before oxygen-glucose deprivation (OGD. The role of netrin-1 was further explored by examining its receptors and their function. We found that netrin-1 infusion improved neurological function, attenuated secondary impairment of BBB by up-regulating the levels of tight junction proteins and diminishing extravasation of albumin, with autophagy activation 14 days after MCAO. Netrin-1 also enhanced cell survival and autophagy activity in OGD-treated cells, inhibited by UNC5H2 siRNA transfection. Furthermore, the beneficial effects of netrin-1 were suppressed by PI3K inhibitors 3-Methyladenine and LY294002. Our results showed that netrin-1 ameliorated BBB impairment secondary to ischemic stroke by promoting tight junction function and endothelial survival. PI3K-mediated autophagy activation depending on UNC5H2 receptor could be an underlying mechanism.

    Few studies on long-term functional outcome have been conducted in post-stroke patients in China. The objective of this study was to conduct a nationwide survey in China to investigate the 5-year prevalence of post-stroke disability and its correlation factors. A total of 893 patients with ischemic stroke were included. Demographic, clinical and neuro-imaging information were collected with standardized instruments that assessed stroke severity, depression, cognitive impairment, stroke recurrence and physical disability. Disability was assessed with the modified Ranking Score (mRS), of which a cutoff score ≥2 indicates disability. Statistical analysis included chi-square tests, two independent samples t-tests, Mann-Whitney U test and multiple logistic regression analysis. The frequency of disability in this study population was 45%. Multivariate analyses revealed that older age, lower education level, previous history of stroke, stroke severity at admission, depression, cognitive impairment at 3 months, and stroke recurrence within 5 years follow up were all significantly associated with post-stroke disability. The disability rate in 5-year post-stroke was high in Chinese patients. Treatment of depression, secondary prevention of stroke and rehabilitation may benefit disabled patients with stroke in China.

    We aimed to examine whether the efficacy of folic acid therapy in the primary prevention of stroke is jointly affected by smoking status and baseline folate levels in a male population in a post hoc analysis of the CSPPT (China Stroke Primary Prevention Trial). Eligible participants of the CSPPT were randomly assigned to a double-blind daily treatment of a combined enalapril 10-mg and folic acid 0.8-mg tablet or an enalapril 10-mg tablet alone. In total, 8384 male participants of the CSPPT were included in the current analyses. The primary outcome was first stroke. The median treatment duration was 4.5 years. In the enalapril-alone group, the first stroke risk varied by baseline folate levels and smoking status (never versus ever). Specifically, there was an inverse association between folate levels and first stroke in never smokers ( P for linear trend=0.043). However, no such association was found in ever smokers. A test for interaction between baseline folate levels and smoking status on first stroke was significant ( P =0.045). In the total sample, folic acid therapy significantly reduced the risk of first stroke in never smokers with folate deficiency (hazard risk, 0.36; 95% confidence interval, 0.16-0.83) and in ever smokers with normal folate levels (hazard risk, 0.69; 95% confidence interval, 0.48-0.99). Baseline folate levels and smoking status can interactively affect the risk of first stroke. Our data suggest that compared with never smokers, ever smokers may require a higher dosage of folic acid to achieve a greater beneficial effect on stroke. Our findings need to be confirmed by future randomized trials. URL: https://www.clinicaltrials.gov. Unique identifier: NCT00794885. © 2017 American Heart Association, Inc.

    Full Text Available Effect of hyperlipidemia on morbidity and mortality in elderly patients is considered. Authors also cover issues of efficacy and safety of lipid-lowering therapy in primary and secondary prevention of cardiovascular diseases in patients ≥80 years of age who are the most quickly growing group of population and have the highest cardiovascular risk. They stress the need to take into account polymorbidity and polypharmacy that increase the risk of adverse reactions due to the use of both statins and their drug-drug interactions, which requires an assessment of risk/benefit ratio. In addition, there is a need for development of reliable prognostic tools to predict relevant outcomes (e.g., stroke, decrease in functionality/independence, quality of life reduction and rationales for lipid-lowering therapy in the elderly and also their adherence to treatment.

    An American Heart Association/American Stroke Association (AHA/ASA) writing committee has recently recommended that tissue evidence of cerebral infarction associated with temporary symptoms (CITS) lasting Management for Preventing Recurrent Stroke in Intracranial Stenosis (SAMMPRIS) trial. We compared outcomes in the medical (n = 227) and stenting (n = 224) groups in SAMMPRIS using the following primary end point (new components in bold): any stroke, CITS, or death within 30 days after enrollment or within 30 days after a revascularization procedure for the qualifying lesion during follow-up; or ischemic stroke or CITS in the territory of the qualifying artery beyond 30 days. We also compared the use of brain magnetic resonance imaging (MRI) after transient ischemic attacks (TIAs) in both treatment groups. By considering CITS as equivalent to stroke, the number of primary end points increased from 34 to 43 in the medical group and from 52 to 66 in the stenting group of SAMMPRIS. The Kaplan-Meier curves for the primary end points in the 2 groups were significantly different (P = .009). The percentage of patients with reported TIAs who underwent brain MRI was 69% in the medical group and 61% in the stenting group (P = .40). Using the AHA/ASA definition of stroke resulted in a substantially higher primary end point rate in both treatment groups and an even higher benefit from medical therapy over stenting than originally shown in SAMMPRIS. The higher rate of CITS in the stenting group was not due to ascertainment bias. Published by Elsevier Inc.

    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.

    Falls are one of the most common medical complications post-stroke. Physical exercise, particularly exercise that challenges balance, reduces the risk of falls among healthy and frail older adults. However, exercise has not proven effective for preventing falls post-stroke. Falls ultimately occur when an individual fails to recover from a loss of balance. Thus, training to specifically improve reactive balance control could prevent falls. Perturbation training aims to improve reactive balance control by repeatedly exposing participants to postural perturbations. There is emerging evidence that perturbation training reduces fall rates among individuals with neurological conditions, such as Parkinson disease. The primary aim of this work is to determine if perturbation-based balance training can reduce occurrence of falls in daily life among individuals with chronic stroke. Secondary objectives are to determine the effect of perturbation training on balance confidence and activity restriction, and functional balance and mobility. Individuals with chronic stroke will be recruited. Participants will be randomly assigned to one of two groups: 1) perturbation training, or 2) 'traditional' balance training. Perturbation training will involve both manual perturbations (e.g., a push or pull from a physiotherapist), and rapid voluntary movements to cause a loss of balance. Training will occur twice per week for 6 weeks. Participants will record falls and activity for 12 months following completion of the training program. Standardized clinical tools will be used to assess functional balance and mobility, and balance confidence before and after training. Falls are a significant problem for those with stroke. Despite the large body of work demonstrating effective interventions, such as exercise, for preventing falls in other populations, there is little evidence for interventions that prevent falls post-stroke. The proposed study will investigate a novel and promising

    BACKGROUND: Secondary prevention pharmacotherapy in post-myocardial infarction (MI) patients reduces the risk of subsequent coronary events and overall mortality. International guidelines recommend use of aspirin, beta-blockers, ACE inhibitors and statins in post-MI patients. AIMS: We performed this audit to review the compliance of prescribing practices, in a regional hospital in Ireland, with international guidelines for secondary prevention of coronary artery disease. METHODS: We performed a retrospective case review of 172 patients diagnosed with MI during a 1-year period between January and December 2007. RESULTS: A total of 134 patients fulfilled the inclusion criteria. On discharge, aspirin was prescribed to 131 (97.76%) patients, clopidogrel to 126 (94%), beta-blockers to 117 (87%), ACE inhibitor to 87 (65%), ARB to 10 (7%) and statins to 116 (87%). CONCLUSION: Our audit shows that targets for prescription of secondary prevention medications were not met in a small but significant proportion of patients and calls for review of discharge practices and education to improve compliance with guidelines.

    Current European atrial fibrillation (AF) guidelines have assigned a strong recommendation for the initiation of antithrombotic therapy to prevent thromboembolism in all but those AF patients at low risk (or with contraindications). Furthermore, the selection of antithrombotic therapy is based on the absolute risks of thromboembolism and bleeding, and the relative risk and benefit for a given patient. By their very mechanism of action, antithrombotic agents used for stroke prevention in AF will potentially increase the risk of bleeding events. Moreover, the introduction of novel oral anticoagulation agents have introduced new, hitherto ill-defined, deficiencies in the authors' knowledge with respect to anticoagulation monitoring, availability of direct antidotes, drug-drug interactions and the ability to appropriately control and reverse their actions if bleeding events occur. The authors present a comprehensive review on all aspects of bleeding related to currently licensed antithrombotic agents used for stroke prevention in patients with AF.

    Hypertrophic cardiomyopathy is a frequent cause of sudden death. Clinical practice guidelines indicate defibrillator implantation for primary prevention in patients with 1 or more risk factors and for secondary prevention in patients with a history of aborted sudden death or sustained ventricular arrhythmias. The aim of the present study was to analyze the follow-up of patients who received an implantable defibrillator following the current guidelines in nonreferral centers for this disease. This retrospective observational study included all patients who underwent defibrillator implantation between January 1996 and December 2012 in 3 centers in the province of Barcelona. The study included 69 patients (mean age [standard deviation], 44.8 [17] years; 79.3% men), 48 in primary prevention and 21 in secondary prevention. The mean number of risk factors per patient was 1.8 in the primary prevention group and 0.5 in the secondary prevention group (P=.029). The median follow-up duration was 40.5 months. The appropriate therapy rate was 32.7/100 patient-years in secondary prevention and 1.7/100 patient-years in primary prevention (P<.001). Overall mortality was 10.1%. Implant-related complications were experienced by 8.7% of patients, and 13% had inappropriate defibrillator discharges. In patients with a defibrillator for primary prevention, the appropriate therapy rate is extremely low, indicating the low predictive power of the current risk stratification criteria.

    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.

    Rationale Paroxysmal atrial fibrillation is a common and preventable cause of devastating strokes. However, currently available monitoring methods, including Holter monitoring, cardiac telemetry and event loop recorders, have drawbacks that restrict their application in the general stroke population. AliveCor™ heart monitor, a novel device that embeds miniaturized electrocardiography (ECG) in a smartphone case coupled with an application to record and diagnose the ECG, has recently been shown to provide an accurate and sensitive single lead ECG diagnosis of atrial fibrillation. This device could be used by nurses to record a 30-s ECG instead of manual pulse taking and automatically provide a diagnosis of atrial fibrillation. Aims To compare the proportion of patients with paroxysmal atrial fibrillation detected by AliveCor™ ECG monitoring with current standard practice. Sample size 296 Patients. Design Consecutive ischemic stroke and transient ischemic attack patients presenting to participating stroke units without known atrial fibrillation will undergo intermittent AliveCor™ ECG monitoring administered by nursing staff at the same frequency as the vital observations of pulse and blood pressure until discharge, in addition to the standard testing paradigm of each participating stroke unit to detect paroxysmal atrial fibrillation. Study outcome Proportion of patients with paroxysmal atrial fibrillation detected by AliveCor™ ECG monitoring compared to 12-lead ECG, 24-h Holter monitoring and cardiac telemetry. Discussion Use of AliveCor™ heart monitor as part of routine stroke unit nursing observation has the potential to be an inexpensive non-invasive method to increase paroxysmal atrial fibrillation detection, leading to improvement in stroke secondary prevention.

    Full Text Available Aim. To study the factors associated with a poor annual prognosis in patients with acute stroke and prognostic role of pathological ankle-brachial index (ABI.Material and methods. The study included 345 patients (age 63.6±7.8 years, 181 males and 164 females with ischemic stroke that were observed for 1 year. All patients were divided into 2 groups: Group 1 included patients with favorable annual outcome of stroke; Group 2 included patients that during a year had any clinical events including death. All patients underwent a standard neurological and instrumental examination including assessment of peripheral arteries status by sphygmomanometry.Results. Both groups did not differ by age and sex. The frequency of unfavorable outcomes (death, re-stroke, cardiovascular events 1 year after ischemic stroke was 29.5%. Chronic heart failure, atrial fibrillation, previous cardiovascular events, presence of peripheral atherosclerosis, overweight were identified most commonly in Group 2. Patients of Group 2 initially had a rough neurological deficit. The pathological ABI was detected in 70.7% of patients in Group 2 vs 33.8% of patients in Group 1 (p=0.000001. A strong relationship of pathological ABI with a poor outcome of stroke was found by regression analysis.Conclusions. Detection of pathological ABI in patients with ischemic stroke makes it possible to reveal peripheral atherosclerosis and to carry out the targeted preventive measures in these patients. Risk stratification can contribute to more individual and effective secondary prevention in patients with cerebrovascular disease.

    Patients with atrial fibrillation (AF) have a high risk of stroke and mortality, which can be considerably reduced by oral anticoagulants (OAC). Recently, four non-vitamin-K oral anticoagulants (NOACs) were compared with warfarin in large randomized trials for the prevention of stroke and systemic embolism. Today's clinician is faced with the difficult task of selecting a suitable OAC for a patient with a particular clinical profile or a particular pattern of risk factors and concomitant diseases. We reviewed analyses of subgroups of patients from trials of vitamin K antagonists vs. NOACs for stroke prevention in AF with the aim to identify patient groups who might benefit from a particular OAC more than from another. In the first of a two-part review, we discuss the choice of NOAC for stroke prevention in the following subgroups of patients with AF: (i) stable coronary artery disease or peripheral artery disease, including percutaneous coronary intervention with stenting and triple therapy; (ii) cardioversion, ablation and anti-arrhythmic drug therapy; (iii) mechanical valves and rheumatic valve disease, (iv) patients with time in therapeutic range of >70% on warfarin; (v) patients with a single stroke risk factor (CHA2DS2VASc score of 1 in males, 2 in females); and (vi) patients with a single first episode of paroxysmal AF. Although there are no major differences in terms of efficacy and safety between the NOACs for some clinical scenarios, in others we are able to suggest that particular drugs and/or doses be prioritized for anticoagulation.

  7. Dietary Polyphenols in the Prevention of Stroke

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Polyphenols have an important protective role against a number of diseases, such as atherosclerosis, brain dysfunction, stroke, cardiovascular diseases, and cancer. Cardiovascular diseases are the number one cause of death worldwide: more people die annually from cardiovascular diseases than from any other cause. The most important behavioural risk factors of heart disease and stroke are unhealthy diet, physical inactivity, tobacco use, and excess alcohol intake. The dietary consumption of polyphenols has shown to be inversely associated with morbidity and mortality by cardio- and cerebrovascular diseases. It is well-known that the protective effects of polyphenols in vivo depend on the grade how they are extracted from food and on their intestinal absorption, metabolism, and biological action with target tissues. The aim of this review was to summarise the relation between polyphenols of different plant sources and stroke in human intervention studies, animal models, and in vitro studies.

    Background: Stroke is a leading cause of mortality and morbidity. It is associated with excessive bone loss and risk of fracture in stroke patients is high. The P2Y12R antagonist and platelet inhibitor, clopidogrel, is widely used for secondary prevention after a stroke. However, recent studies...... have shown that clopidogrel has negative effects on bone and that long-term clopidogrel use is associated with increased fracture risk. The purpose of the current study was therefore to investigate the association of clopidogrel treatment with risk of fractures in stroke and TIA patients.......Methods:The study was a cohort study including all subjects who were prescribed clopidogrel between 1996 and 2008 in Denmark (n= 77,503).

    Many patients with transient ischemic attack (TIA) receive initial assessments by general practitioners (GPs) who may lack TIA management experience. In a randomized controlled trial (RCT), we showed that electronic decision support for GPs improves patient outcomes and guideline adherence. Some stroke services prefer to improve referrer expertise through TIA/stroke education sessions instead of promoting TIA decision aids or triaging tools. This is a secondary analysis of whether a GP education session influenced TIA management and outcomes. Post hoc analysis of a multicenter, single blind, parallel group, cluster RCT comparing TIA/stroke electronic decision support guided GP management with usual care to assess whether a pretrial TIA/stroke education session also affected RCT outcomes. Of 181 participating GPs, 79 (43.7%) attended an education session and 140 of 291 (48.1%) trial patients were managed by these GPs. There were fewer 90-day stroke events and 90-day vascular events or deaths in patients treated by GPs who attended education; 2 of 140 (1.4%) and 10 of 140 (7.1%) respectively, compared with those who did not; 5 of 151 (3.3%), and 14 of 151 (9.3%), respectively. Logistic regression for association between 90-day stroke and 90-day vascular events or death and education, however, was nonsignificant (odds ratio [OR] .42 (.08 to 2.22), P = .29 and .59 (95% confidence interval [CI] .27 to 1.29), P = .18 respectively. Guideline adherence was not improved by the education session: OR .84 (95% CI .49 to 1.45), P = .54. In the described setting, a GP TIA/stroke education session did not significantly enhance guideline adherence or reduce 90-day stroke or vascular events following TIA.

  13. A Surgeon’s View on Endarterectomy and Stenting in 2011: Lest We Forget, It’s All About Preventing Stroke

    International Nuclear Information System (INIS)

    2012-01-01

    It has been nearly 60 years since Felix Eastcott published his seminal paper on carotid reconstruction, which paved the way for carotid endarterectomy (CEA) and then carotid artery stenting (CAS) to assume prominent roles in the prevention of stroke. Yet the ensuing 60 years has witnessed repeated cycles of challenges to practice, professional mistrust, conflicts of interest, dogmatic retention of traditional management strategies, inappropriate corporate interventions, and a general failure to adapt to new evidence. Even the performance of large-scale randomised trials has been associated with rancour and a lack of consensus. This article reviews the history of invasive interventions in the treatment of carotid disease and makes a plea to both the surgical and interventional communities that the fundamental priority must always be the prevention of stroke. It concludes with an appeal for colleagues to collaborate to determine how best to treat patients during the hyperacute period after the onset of symptoms and to identify a smaller cohort of asymptomatic patients who are truly at high risk for stroke in whom to target CAS or CEA.

    Full Text Available Abstract Background Coronary heart disease (CHD is a significant cause of health and economic burden. Secondary prevention programs play a pivotal role in the treatment and management of those affected by CHD although participation rates are poor due to patient, provider, health system and societal-level barriers. As such, there is a need to develop innovative secondary prevention programs to address the treatment gap. Telephone-delivered care is convenient, flexible and has been shown to improve behavioural and clinical outcomes following myocardial infarction (MI. This paper presents the design of a randomised controlled trial to evaluate the efficacy of a six-month telephone-delivered secondary prevention program for MI patients (ProActive Heart. Methods 550 adult MI patients have been recruited over a 14 month period (December 2007 to January 2009 through two Brisbane metropolitan hospitals, and randomised to an intervention or control group (n = 225 per group. The intervention commences within two weeks of hospital discharge delivered by study-trained health professionals ('health coaches' during up to 10 × 30 minute scripted telephone health coaching sessions. Participants also receive a ProActive Heart handbook and an educational resource to use during the health coaching sessions. The intervention focuses on appropriate modification of CHD risk factors, compliance with pharmacological management, and management of psychosocial issues. Data collection occurs at baseline or prior to commencement of the intervention (Time 1, six months follow-up or the completion of the intervention (Time 2, and at 12 months follow-up for longer term outcomes (Time 3.

    Stroke is one of the leading causes of death and probably the greatest cause of adult disability worldwide. 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. PMID:28203079

    Cognitive beliefs and affective responses to illness and treatment are known to independently predict health behaviours. The purpose of the current study is to assess the relative importance of four psychological domains – specifically, affective illness, cognitive illness, affective treatment and cognitive treatment – for predicting stroke and transient ischemic attack (TIA) survivors’ adherence to stroke prevention medications as well as their objective, categorised stroke risk. We assessed these domains among stroke/TIA survivors (n = 600), and conducted correlation and regression analyses with concurrent and prospective outcomes to determine the relative importance of each cognitive and affective domain for adherence and stroke risk. As hypothesised, patients’ affective treatment responses explained the greatest unique variance in baseline and six-month adherence reports (8 and 5%, respectively, of the variance in adherence, compared to 1–3% explained by other domains). Counter to hypotheses, patients’ cognitive illness beliefs explained the greatest unique variance in baseline and six-month objective categorised stroke risk (3 and 2%, respectively, compared to 0–1% explained by other domains). Results indicate that domain type (i.e. cognitive and affective) and domain referent (illness and treatment) may be differentially important for providers to assess when treating patients for stroke/TIA. More research is required to further distinguish between these domains and their relative importance for stroke prevention. PMID:25220292

    Background Stroke is associated with the development of cognitive impairment and dementia. We assessed the effect of intensive blood pressure (BP) and/or lipid lowering on cognitive outcomes in patients with recent stroke in a pilot trial. Methods In a multicentre, partial-factorial trial, patients with recent stroke, absence of dementia, and systolic BP (SBP) 125–170 mmHg were assigned randomly to at least 6 months of intensive (target SBP Addenbrooke’s Cognitive Examination-Revised (ACE-R). Results We enrolled 83 patients, mean age 74.0 (6.8) years, and median 4.5 months after stroke. The median follow-up was 24 months (range 1–48). Mean BP was significantly reduced with intensive compared to guideline treatment (difference –10·6/–5·5 mmHg; pcognition, intensive BP and lipid lowering were feasible and safe, but did not alter cognition over two years. The association between intensive lipid lowering and improved scores for some secondary outcomes suggests further trials are warranted. Trial Registration ISRCTN ISRCTN85562386 PMID:28095412

The Outcomes in Patients with TIA and Cerebrovascular Disease (OPTIC) study is an international prospective study of patients aged 45 years or older who required secondary prevention of stroke [following either an acute transient ischemic attack, minor ischemic strokes, or recent (less than six-months previous), stable, first-ever, nondisabling ischemic stroke]. A total 3635 patients from 245 centers in 17 countries in four regions (Latin America, Middle East, North Africa, South Africa) were enrolled between 2007 and 2008. The outcome measure was the two-year rate of a composite of major vascular events (vascular death, myocardial infarction and stroke). During the two-year follow-up period, 516 patients experienced at least one major cardiovascular event, resulting in an event rate of 15·6% (95% confidence interval 14·4-16·9%).

    The aim of the Synergium was to devise and prioritize new ways of accelerating progress in reducing the risks, effects, and consequences of stroke. 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. 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 centralized electronic archives and

    We examined blood pressure 1 year after stroke discharge and its association with treatment intensification. We examined the systolic blood pressure (SBP) stratified by discharge SBP (≤140, 141-160, or >160 mm Hg) among a national cohort of Veterans discharged after acute ischemic stroke. Hypertension treatment opportunities were defined as outpatient SBP >160 mm Hg or repeated SBPs >140 mm Hg. Treatment intensification was defined as the proportion of treatment opportunities with antihypertensive changes (range, 0%-100%, where 100% indicates that each elevated SBP always resulted in medication change). Among 3153 patients with ischemic stroke, 38% had ≥1 elevated outpatient SBP eligible for treatment intensification in the 1 year after stroke. Thirty percent of patients had a discharge SBP ≤140 mm Hg, and an average 1.93 treatment opportunities and treatment intensification occurred in 58% of eligible visits. Forty-seven percent of patients discharged with SBP 141 to160 mm Hg had an average of 2.1 opportunities for intensification and treatment intensification occurred in 60% of visits. Sixty-three percent of the patients discharged with an SBP >160 mm Hg had an average of 2.4 intensification opportunities, and treatment intensification occurred in 65% of visits. Patients with discharge SBP >160 mm Hg had numerous opportunities to improve hypertension control. Secondary stroke prevention efforts should focus on initiation and review of antihypertensives before acute stroke discharge; management of antihypertensives and titration; and patient medication adherence counseling. © 2014 American Heart Association, Inc.

    We describe one male, 49-year-old diabetic patient in whom regressive stroke with aphasia and right-sided hemiparesia was related to multiple small emboli in the left paraventricular cortex. Simultaneous presence of several cholesterol emboli in the left eye ground and detection of an atheromatous plaque at the homolateral carotid bifurcation let assume that the cerebral emboli originated from that plaque and also consisted of cholesterol crystals. The patient was discharged on low-dose aspirin (100 mg/day) after neurologic improvement. Follow-up at one year revealed clinical stability, recurrence of the cholesterol emboli at the eye ground examination and no change of the carotid plaque. Cholesterol embolization with renal failure, hypertension and peripheral arterial occlusions causing skin ulcerations is classical in case of atheromatous aortic disease but stroke has rarely been reported in this syndrome. However, more frequent use of invasive procedures (arteriography, transluminal angioplasty, vascular surgery) or thrombolytic treatment might increase its incidence in the near future.

    Stroke is the third leading cause of death in Bangladesh. The World Health Organization ranks Bangladesh's mortality rate due to stroke as number 84 in the world. The reported prevalence of stroke in Bangladesh is 0.3%, although no data on stroke incidence have been recorded. Hospital-based studies conducted in past decades have indicated that hypertension is the main cause of ischaemic and haemorrhagic stroke in Bangladesh. The high number of disability-adjusted life-years lost due to stroke (485 per 10,000 people) show that stroke severely impacts Bangladesh's economy. Although two non-governmental organizations, BRAC and the Centre for the Rehabilitation of the Paralysed, are actively involved in primary stroke prevention strategies, the Bangladeshi government needs to emphasize healthcare development to cope with the increasing population density and to reduce stroke occurrence. © 2012 The Authors.

    Sudden death and catastrophic injuries during sport can be attenuated with the implementation of evidence-based health and safety policies. However, the extent of the implementation of these policies within secondary school athletics is unknown. To provide an assessment of the implementation of health and safety policies pertaining to the leading causes of sudden death and catastrophic injuries in sport within secondary school athletics in the United States. Descriptive epidemiology study. A rubric for evidence-based practices for preventing the leading causes of death and catastrophic injuries in sport was created. The rubric comprised 5 equally weighted sections for sudden cardiac arrest, head injuries, exertional heat stroke, appropriate medical coverage, and emergency preparedness. State high school athletic association (SHSAA) policies, enacted legislation, and Department of Education policies were extensively reviewed for all 50 states and the District of Columbia. States meeting the specific criteria in the rubric, which required policies to be mandated for all SHSAA member schools, were awarded credit; the weighted scores were tabulated to calculate an aggregate score. States were then ranked from 1 (best) to 51 (worst) based on the aggregate score achieved. The median score on the rubric was 47.1% (range, 23.00%-78.75%). States ranked 1 through 10 (from 78.75% to 56.98%) were North Carolina, Kentucky, Massachusetts, New Jersey, South Dakota, Missouri, Washington, Hawaii, Wisconsin, and Georgia, respectively. States ranked 11 through 20 (from 56.03% to 50.55%) were Arkansas, New York, Mississippi, West Virginia, Oregon, Illinois, Tennessee, Arizona, Texas, and District of Columbia, respectively. States ranked 21 through 30 (from 49.40% to 44.00%) were Virginia, Pennsylvania, Florida, New Mexico, Alabama, Maine, Rhode Island, Indiana, Nevada, and Utah, respectively.

  11. Benefits of aerobic exercise after stroke.

    1996-05-01

    The debilitating loss of function after a stroke has both primary and secondary effects on sensorimotor function. Primary effects include paresis, paralysis, spasticity, and sensory-perceptual dysfunction due to upper motor neuron damage. Secondary effects, contractures and disuse muscle atrophy, are also debilitating. This paper presents theoretical and empirical benefits of aerobic exercise after stroke, issues relevant to measuring peak capacity, exercise training protocols, and the clinical use of aerobic exercise in this patient population. A stroke, and resulting hemiparesis, produces physiological changes in muscle fibres and muscle metabolism during exercise. These changes, along with comorbid cardiovascular disease, must be considered when exercising stroke patients. While few studies have measured peak exercise capacity in hemiparetic populations, it has been consistently observed in these studies that stroke patients have a lower functional capacity than healthy populations. Hemiparetic patients have low peak exercise responses probably due to a reduced number of motor units available for recruitment during dynamic exercise, the reduced oxidative capacity of paretic muscle, and decreased overall endurance. Consequently, traditional methods to predict aerobic capacity are not appropriate for use with stroke patients. Endurance exercise training is increasingly recognised as an important component in rehabilitation. An average improvement in maximal oxygen consumption (VO2max) of 13.3% in stroke patients who participated in a 10-week aerobic exercise training programme has been reported compared with controls. This study underscored the potential benefits of aerobic exercise training in stroke patients. In this paper, advantages and disadvantages of exercise modalities are discussed in relation to stroke patients. Recommendations are presented to maximise physical performance and minimise potential cardiac risks during exercise.

    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.

    Stroke survivors live with varied degrees of disabilities and cares are provided largely by the informal caregivers. This study investigated informal caregivers' burden and strains of caring for stroke patients. This study involved 157 (81 males and 76 females) informal caregivers of stroke survivors receiving care in all secondary and tertiary health institutions with physiotherapy services in Lagos State, Nigeria. Information was collected through self-administered questionnaire during clinic-hours. Data was analyzed using Spearman's Rank Correlation Coefficient. The patients' age ranged between 20 and 79 (mean=59.6 ± 14.6 years). Sixty-one had haemorrhagic stroke while 96 had ischaemic stroke. The informal caregivers' age was 39.2 ± 12.8 years (range: 17-36 years). More (60.8%) participants reported moderate objective while 79.2% had mild subjective burdens. The following factors significantly increased (Pfinancial well-beings of the informal caregivers. Caring for stroke survivors put social, emotional, health and financial burdens and strains on the informal caregivers. These burdens and strains increase with duration of stroke, intimacy, smaller number of caregivers and length of daily caregiving. Therefore, informal caregivers should be involved in the rehabilitation plan for stroke patients and their well-being should also be given adequate attention. Copyright © 2015 Elsevier Masson SAS.

    Full Text Available Myxomas, the most common primary cardiac tumors, are known as a source of cardiogenic emboli. The possibility of their early detection has made them of great importance for emergency medicines. Detection of the disease is probable at early stages using echocardiography and associate complications such as syncope, cerebral embolic ischemic strokes, and sudden death. We report experience of a rare case of juvenile acute stroke in a patient with cardiac myxoma affecting all cardiac chambers presenting to the emergency department. In young stroke patients with signs and symptoms compatible with cardiovascular involvement, cardiogenic emboli should be taken into consideration; early echocardiographic studies are highly recommended. Prompt myxoma resection is required in both asymptomatic and stroke patients in whom intravenous thrombolysis course has not been implemented due to any limitations.

    2014-02-01

    Whereas statins and acetylsalicylic acid (ASA) are considered gold standard for secondary prevention following myocardial infarction or atherotrombotic stroke, there are inconsistent data on the use of these drugs for primary prevention in patients with increased cardiovascular risk. Some meta-analyses indicated that the use of statins and ASA for primary prevention of cardiovascular disease can reduce the risk of cardiovascular events such as ischemic stroke or myocardial infarction. However, the effects of primary prevention with statins and ASA on mortality varied in the data included in these meta-analyses. Therefore the guidelines of the German College of General Practitioners and Family Physicians recommend primary prevention with statins and ASA only in those patients who have a 10-year risk of cardiovascular events which exceeds 20 %. Divergently, primary prevention with ASA is not recommended by the European Society of Cardiology. Observational studies suggested that treatment success of primary prevention with statins and ASA depends on various factors such as adherence to medication and prescription behavior of physicians. This review summarizes the current literature on primary prevention of cardiovascular events with ASA and statins. © Georg Thieme Verlag KG Stuttgart · New York.

    High plasma total homocysteine (tHcy) has been associated with cognitive impairment but lowering tHcy with B-vitamins has produced equivocal results. We aimed to determine whether B-vitamin supplementation would reduce tHcy and the incidence of new cognitive impairment among individuals with stroke or transient ischemic attack≥6 months previously. A total of 8164 patients with stroke or transient ischemic attack were randomly allocated to double-blind treatment with one tablet daily of B-vitamins (folic acid, 2 mg; vitamin B6, 25 mg; vitamin B12, 500 μg) or placebo and followed up for 3.4 years (median) in the VITAmins TO Prevent Stroke (VITATOPS) trial. For this prespecified secondary analysis of VITATOPS, the primary outcome was a new diagnosis of cognitive impairment, defined as a Mini-Mental State Examination (MMSE) score6 months after the qualifying stroke; 2608 participants were cognitively unimpaired (MMSE≥24), of whom 2214 participants (1110 B-vitamins versus 1104 placebo) had follow-up MMSEs during 2.8 years (median). At final follow-up, allocation to B-vitamins, compared with placebo, was associated with a reduction in mean tHcy (10.2 μmol/L versus 14.2 μmol/L; Pvitamin B6, and vitamin B12 to a self-selected clinical trial cohort of cognitively unimpaired patients with previous stroke or transient ischemic attack lowered mean tHcy but had no effect on the incidence of cognitive impairment or cognitive decline, as measured by the MMSE, during a median of 2.8 years.

    Can Feng

    Full Text Available Coronary heart disease (CHD patients who have undergone percutaneous coronary intervention (PCI have higher rates of depression than the general population. However, few researchers have assessed the impact of depression on the secondary prevention of CHD in China.The main purpose of this investigation was to explore the relationship between depression and secondary prevention of CHD in Chinese patients after PCI.This descriptive, cross-sectional one-site study recruited both elective and emergency PCI patients one year after discharge. Data from 1934 patients were collected in the clinic using questionnaires and medical history records between August 2013 and September 2015. Depression was evaluated by the 9-item Patient Health Questionnaire. Secondary prevention of CHD was compared between depression and non-depression groups.We found that depression affected secondary prevention of CHD in the following aspects: lipid levels, blood glucose levels, smoking status, physical activity, BMI, and rates of medication use.Depressive patients with CHD are at increased risk of not achieving the lifestyle and risk factor control goals recommended in the 2006 AHA guidelines. Screening should focus on patients after PCI because treating depression can improve outcomes by improving secondary prevention of CHD.

    To evaluate the 5-year impact of stroke and TIA on utility and quality-adjusted survival. TIA and stroke patients from a UK population-based study (Oxford Vascular Study) were recruited from 2002 to 2007, and followed up until 2012. Quality of life was assessed over 5 years using the EQ-5D (EuroQol-5 Dimensions), with responses converted into utilities ranging from -0.59 (worse than death) to 1 (perfect health), using UK population valuations. Utilities for stroke and TIA patients were compared with those in matched controls obtained from the 2006 Health Survey for England. Five-year quality-adjusted life years were estimated by combining utility and survival information. Four hundred forty TIA and 748 stroke patients were ascertained and included. Utility remained constant at approximately 0.78 over the 5 years after TIA. Utility improved from 0.64 one month after stroke to 0.70 at 6 months (p = 0.006), remaining at approximately 0.70 thereafter. Matched controls had considerably higher utility levels than stroke/TIA patients (0.85, p TIA and 2.21 (2.15-2.37) after stroke, varying considerably by severity (minor: 2.94; moderate: 1.65; and severe: 0.70). Quality-adjusted survival is low over the 5 years after stroke and TIA, with severity and recurrent stroke being major predictors. There remains considerable scope for improvements in acute treatment and secondary prevention to improve the quality of life after TIA and stroke.

    This study aimed to investigate the effectiveness of monotherapy aspirin and warfarin for stroke prevention in low-risk atrial fibrillation (AF) by using a population-based cohort study in Taiwan. A newly diagnosed low-risk AF patient cohort were identified by using National Health Insurance Research Database (NHIRD) in Taiwan in 2008. The study cohort was observed with a follow-up of 2 years to examine the onset of ischemic stroke (IS) (to 2010). The longitudinal data were analyzed by using generalized estimation equations (GEE). A total of 8,065 newly-diagnosed low-risk AF patients were identified in 2008. 7.4% were prescribed with aspirin and 4.6% were prescribed with warfarin. The GEE results showed that low-risk AF patients with hypertension who received warfarin were associated with a statistically significant 58.4% reduction of IS risk (OR = 0.416, p = 0.024, 95% CI 0.194-0.891). Additionally, low-risk AF patients with hyperlipidemia who received warfarin were associated with a 69.3% reduction of IS risk (OR = 0.307, p = 0.044, 95% CI 0.097-0.969). Warfarin is suggested to be prescribed in preventing ischemic stroke for low-stroke-risk atrial fibrillation patients with hypertension and hyperlipidemia.

    A cerebral artery infarction is an important differential diagnosis in the newborn with neurological abnormalities. Based on clinical data, its incidence is estimated to be 1 in 4000 newborns. Since the course is often subclinical, the true incidence is probably higher. Diagnosis: Cerebral ultrasound and Doppler sonography as readily available screening tools play a central role in the initial diagnosis of neonatal cerebral infarction. Definitive diagnosis is made by computed tomography or magnetic resonance imaging. Beside symptomatic anticonvulsive therapy, treatment aims at the prevention of secondary ischemic injury. Discussion: Three term infants with different clinical courses of neonatal stroke are presented to sensitize the clinician and the radiologist for this probably underdiagnosed entity. The role of imaging modalities in the diagnosis and follow-up of neonatal cerebral infarction is discussed. (orig.) [de

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

    Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used for their analgesic, antipyretic, and antiinflammatory properties, and aspirin is increasingly employed in the primary and secondary prevention of cardiovascular disease and ischemic stroke. Despite undisputed therapeutic efficacy for these indications, all NSAIDs impart a considerable risk of peptic ulcer disease and upper gastrointestinal hemorrhage. A growing body of evidence supports an association between non-aspirin NSAIDs and acute coronary syndromes, and an expanding understanding of the gastroduodenal effects of aspirin, COX-2 selective agents, clopidogrel, and Helicobacter pylori synergism fuel controversies in NSAID use. In this review, we discuss risk stratification of patients taking NSAIDs and the appropriate application of proven gastro-protective strategies to decrease the incidence of gastrointestinal hemorrhage based upon an individualized assessment of risk for potential toxicities. Prevention of NSAID-related gastropathy is an important clinical issue, and therapeutic strategies for both the primary and secondary prevention of adverse events are continually evolving.

    The benefit of reducing the risk of stroke against increasing the risk of renal progression associated with antiplatelet therapy in patients with advanced chronic kidney disease (CKD) is controversial. We enrolled 1301 adult patients with advanced CKD treated with erythropoiesis stimulating agents from January 1, 2002 to June 30, 2009 from the 2005 Longitudinal Health Insurance Database in Taiwan. All of the patients were followed until the development of the primary or secondary endpoints, or the end of the study (December 31, 2011). The primary endpoint was the development of ischemic stroke, and the secondary endpoints included hospitalization for bleeding events, cardiovascular mortality, all-cause mortality, and renal failure. The adjusted cumulative probability of events was calculated using multivariate Cox proportional regression analysis. Adjusted survival curves showed that the usage of aspirin was not associated with ischemic stroke, hospitalization for bleeding events, cardiovascular mortality or all-cause mortality, however, it was significantly associated with renal failure. In subgroup analysis, aspirin use was associated with renal failure in the patients with no history of stroke (HR, 1.41; 95% CI, 1.14-1.73), and there was a borderline interaction between previous stroke and the use of aspirin on renal failure (interaction p=0.0565). There was no significant benefit in preventing ischemic stroke in the patients with advanced CKD who received aspirin therapy. Furthermore, the use of aspirin was associated with the risk of renal failure in the patients with advanced CKD without previous stroke. Copyright © 2016 European Federation of Internal Medicine.

    The evidence for interventions to prevent functional decline in the long term after stroke is lacking. The aim of this trial was to evaluate the efficacy and safety of an 18-month follow-up program of individualized regular coaching on physical activity and exercise. This was a multicentre, pragmatic, single-blinded, randomized controlled trial. Adults (age ≥18 years) with first-ever or recurrent stroke, community dwelling, with modified Rankin Scale coaching on physical activity and exercise every month for 18 consecutive months. The control group received standard care. Primary outcome was the Motor Assessment Scale at end of intervention (18-month follow-up). Secondary measures were Barthel index, modified Rankin Scale, item 14 from Berg Balance Scale, Timed Up and Go test, gait speed, 6-minute walk test, and Stroke Impact Scale. Other outcomes were adverse events and compliance to the intervention assessed by training diaries and the International Physical Activity Questionnaire. Three hundred and eighty consenting participants were randomly assigned to individualized coaching (n=186) or standard care (n=194). The mean estimated difference on Motor Assessment Scale in favor of control group was -0.70 points (95% confidence interval, -2.80, 1.39), P =0.512. There were no differences between the groups on Barthel index, modified Rankin Scale, or Berg Balance Scale. The frequency of adverse events was low in both groups. Results from International Physical Activity Questionnaire and training diaries showed increased activity levels but low intensity of the exercise in the intervention group. The regular individualized coaching did not improve maintenance of motor function or the secondary outcomes compared with standard care. The intervention should be regarded as safe. Despite the neutral results, the health costs related to the intervention should be investigated. URL: https://www.clinicaltrials.gov. Unique identifier: NCT01467206. © 2017 American Heart

    Physical activity and health-related behaviors are important in primary prevention of stroke and are also recommended for secondary prevention. Gender differences in physical activity and health-related behaviors have been reported in various populations and diseased states but data is lacking on stroke survivors. To assess gender disparities in physical activity in stroke patients and to investigate possible reasons for such disparities. This is a cross-sectional study using nationwide data from the 5th Korean National Health and Nutrition Examination Survey (2010-2012). A total of 9539 participants (stroke (n = 170), non-stroke (n = 9369)) between the ages of 40-80, with no problems walking were included. Physical activity, smoking, and alcohol drinking of stroke survivors were assessed by gender and compared with non-stroke groups. Multiple logistic regression was used to estimate the odds ratios (ORs) for insufficient physical activity and possible explanatory variables for gender differences. Women showed higher prevalence of insufficient physical activity after adjusting for age (OR = 7.32, 95% CI: 1.89-28.32) compared to men. Medical conditions such as depression and comorbidities failed to explain the low physical activity in women with stroke but adding socioeconomic factors to the model nullified the gender difference in physical activity. In order to reduce noted gender disparities in physical activity following stroke, more focused effort to increase physical activity in women, especially with lower socioeconomic status, has to be considered.

  15. Magnetic resonance imaging to visualize stroke and characterize stroke recovery: a review

    Full Text Available The global burden of stroke continues to grow. Although stroke prevention strategies (eg. medications, diet and exercise can contribute to risk reduction, options for acute interventions (eg. thrombolytic therapy for ischemic stroke are limited to the minority of patients. The remaining patients are often left with profound neurological disabilities that substantially impact quality of life, economic productivity, and increase caregiver burden. In the last decade, however, the future outlook for such patients has been tempered by movement away from the view that the brain is incapable of reorganizing after injury. Many now view brain recovery after stroke as an area of scientific research with large potential for therapeutic advances, far into the future [1]. As a probe of brain anatomy, function and physiology, magnetic resonance imaging is a noninvasive and highly versatile modality that promises to play a particularly important role in such research, towards improving stroke rehabilitation methods and stroke recovery.

    The clinical benefit of patent foramen ovale (PFO) closure after cryptogenic stroke has been a topic of debate for decades. Recently, 3 randomized controlled trials of PFO closure in patients with cryptogenic stroke demonstrated a significantly reduced risk of recurrent stroke compared with standard medical therapy alone. This meta-analysis was performed to clarify the efficacy of PFO closure for future stroke prevention in this population. A systematic literature search was undertaken. Published pooled data from 5 large randomized clinical trials (CLOSE, RESPECT, Gore REDUCE, CLOSURE I, and PC) were combined and then subsequently analyzed. Enrolled patients with cryptogenic stroke were assigned to receive standard medical care or to undergo endovascular PFO closure, with a primary outcome of reduction in stroke recurrence rate. Secondary outcomes included rates of transient ischemic attack (TIA), composite outcome of stroke, TIA, and death from all causes, and rates of atrial fibrillation events. We analyzed data for 3412 patients. Transcatheter PFO closure resulted in a statistically significant reduced rate of recurrent stroke, compared with medication alone. Patients undergoing closure were 58% less likely to have another stroke. The number needed to treat with PFO closure to reduce recurrent stroke for 1 patient was 40. Endovascular PFO closure was associated with a reduced risk of recurrent stroke in patients with a prior cryptogenic cerebral infarct. Although the absolute stroke reduction was small, these findings are clinically significant, given the young age of this patient population and the patients' lifetime risk of recurrent stroke.

    This research was aimed at clarifying whether high dietary fiber intake has an impact on incidence and risk of stroke at a population level. In 1647 unselected subjects, dietary fiber intake (DFI) was detected in a 12-year population-based study, using other dietary variables, anagraphics, biometrics, blood pressure, heart rate, blood lipids, glucose, insulin, uricaemia, fibrinogenaemia, erytrosedimentation rate, diabetes, insulin resistance, smoking, pulmonary disease and left ventricular hypertrophy as covariables. In adjusted Cox models, high DFI reduced the risk of stroke. In analysis based on quintiles of fiber intake adjusted for confounders, HR for incidence of stroke was lower when the daily intake of soluble fiber was >25 g or that of insoluble fiber was >47 g. In multivariate analyses, using these values as cut-off of DFI, the risk of stroke was lower in those intaking more that the cut-off of soluble (HR 0.31, 0.17-0.55) or insoluble (HR 0.35, 0.19-0.63) fiber. Incidence of stroke was also lower (-50%, p < 0.003 and -46%, p < 0.01, respectively). Higher dietary DFI is inversely and independently associated to incidence and risk of stroke in general population.

    Stress ulcer is one ofacute stroke complications. Giving ranitidine or omeprazole may prevent stress ulcer, but may increase the occurrence of pneumonia. Thus, it will affect the outcome of acute stroke. The method was experimental with a randomized control-group pretest - posttest design. This study divided the subjects into two groups, ranitidine 300mg and omeprazole 20mg group.We observed the patients whether stress ulcer or pneumonia occurred during hospitalization. Then, we measured the outcome by the National Institutes of Health Stroke Scaleand modified Rankin Scale. There were 32 subjects in this study. Only 1 (3.1%) subject suffered stress ulcer, and 3 (3.1%) suffered pneumonia in ranitidine group. Moreover, 2 (6.2%) subjects suffered pneumonia in omeprazole group. The differences were not significant between the two groups (p = 0.31 and p = 0.54). There was no significant effect and difference effect on the administration of both medications to the outcome at day 14. These results indicate that ranitidine and omeprazole have anequal effectiveness in the prevention of stress ulcer and also have equal effect on the occurrence of pneumonia, and both have no effect on the outcome of acute stroke patients.

    Full Text Available Here is identified the tendency to reduce the effectiveness of anti-tobacco prevention work among graduating students of secondary school. This decline may be due to psychological and social reasons. It is shown that risk factors of involving in chemical dependency are meaningfully disclosed in longitudinal studies, whereas the dynamics of personal change during the formation of anti-addictive prevention skills are more fully disclosed in the comparative age sections. The typical phenomena, accompanying the downward trend in prevention, are the growth of problem behavior and the crisis of mass dropout. Such phenomena are so great that they are recognized as a crisis at a state level.

    2013-01-01

    To estimate the cost-effectiveness and cost-utility of dabigatran in the prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation in Portugal. A Markov model was used to simulate patients' clinical course, estimating the occurrence of ischemic and hemorrhagic stroke, transient ischemic attack, systemic embolism, myocardial infarction, and intra- and extracranial hemorrhage. The clinical parameters are based on the results of the RE-LY trial, which compared dabigatran with warfarin, and on a meta-analysis that estimated the risk of each event in patients treated with aspirin or with no antithrombotic therapy. Dabigatran provides an increase of 0.331 life years and 0.354 quality-adjusted life years for each patient. From a societal perspective, these clinical gains entail an additional expenditure of 2978 euros. Thus, the incremental cost is 9006 euros per life year gained and 8409 euros per quality-adjusted life year. The results show that dabigatran reduces the number of events, especially the most severe such as ischemic and hemorrhagic stroke, as well as their long-term sequelae. The expense of dabigatran is partially offset by lower event-related costs and by the fact that INR monitoring is unnecessary. It can thus be concluded that the use of dabigatran in clinical practice in Portugal is cost-effective. Copyright © 2013 Sociedade Portuguesa de Cardiologia. Published by Elsevier España.

    The D-SPIRIT registry is designed to investigate the safety and efficacy of dabigatran etexilate in patients with nonvalvular atrial fibrillation (NVAF) and to collect data on outcomes in clinical practice. The D-SPIRIT is a national, prospective, observational, post-marketing registry involving patients with NVAF who have been taking dabigatran etexilate therapy for stroke prevention for a minimum of 6 months prior to enrollment. The registry will collect and analyze data from routine care, enrolling up to 600 patients in 9 centers. Patients will be followed up for 2 years to evaluate effectiveness and safety. A sample size of 600 subjects is proposed based on the following assumptions; Two-sided significance level of 0.05 (1-sided significance level of 0.025), ischemic stroke incidence rate of 0.768%-1.111%, hemorrhagic stroke incidence rate of 0.109%-0.130%, transient ischemic attack incidence rate of 0.722%-0.623%, therapy discontinuation incidence rate of 40% at day 730, and duration of enrollment period of 12 months with non-uniformed enrollment rate. Ethics approval was given by Dokuz Eylül University Ethics Committee of Clinical Research (2014/54) and approved by the Turkish Ministry of Health. Potential results of D-SPIRIT registry will add data from clinical practice to those from the RE-LY trial to expand knowledge of dabigatran etexilate treatment in patients with NVAF.

    Patients with stroke associated with non-valvular atrial fibrillation (NVAF) are a specific group, and their disease has a considerable social and economic impact. The primary objective of the CONOCES study, the protocol of which is presented here, is to compare the costs of stroke in NVAF patients to those of patients without NVAF in Spanish stroke units from a societal perspective. CONOCES is an epidemiological, observational, naturalistic, prospective, multicentre study of the cost of the illness in a sample of patients who have suffered a stroke and were admitted to a Spanish stroke unit. During a 12-month follow-up period, we record sociodemographic and clinical variables, score on the NIH stroke scale, level of disability, degree of functional dependency according to the modified Rankin scale, and use of healthcare resources (hospitalisation at the time of the first episode, readmissions, outpatient rehabilitation, orthotic and/or prosthetic material, medication for secondary prevention, medical check-ups, nursing care and formal social care services). Estimated monthly income, lost work productivity and health-related quality of life measured with the generic EQ-5D questionnaire are also recorded. We also administer a direct interview to the caregiver to determine loss of productivity, informal care, and caregiver burden. The CONOCES study will provide more in-depth information about the economic and clinical impact of stroke according to whether or not it is associated with NVAF.

    The relationship between blood pressure (BP) and cardiovascular diseases has been extensively documented. However, the benefit of anti-hypertensive drugs differs according to the type of cardiovascular event. Aortic stiffness is tightly intertwined with BP and aorta cross-talk with small arteries. We endeavored to elucidate which BP component and type of vessel remodeling was predictive of the following outcomes: fatal myocardial infarction (MI), fatal stroke, renal -, coronary- or cerebrovascular-related deaths. Large vessel remodeling was estimated by an aortography-based aortic atherosclerosis score (ATS) while small vessel disease was documented by the presence of a hypertensive retinopathy. We included 1031 subjects referred for hypertension workup and assessed outcomes 30 years later. After adjustment for major risk factors, ATS and pulse pressure (PP) were predictive of coronary events while mean BP (MBP) and retinopathy were not. On the contrary, MBP was predictive of cerebrovascular and renal related deaths while ATS and PP were not. Retinopathy was only predictive of cerebrovascular related deaths. Lastly, the aortic atherosclerosis phenotype and increased PP identified patients prone to develop fatal MI whereas the retinopathy phenotype and increased MBP identified patients at higher risk of fatal stroke. These results illustrate the particular feature of the resistive coronary circulation comparatively to the brain and kidneys' low-resistance circulation. Our results advocate for a rational preventive strategy based on the identification of distinct clinical phenotypes. Accordingly, decreasing MBP levels could help preventing stroke in retinopathy phenotypes whereas targeting PP is possibly more efficient in preventing MI in atherosclerotic phenotypes.

    Age-adjusted stroke mortality rates in Israel are higher among Arabs compared with Jews; therefore, knowledge of stroke signs and prevention strategies is especially important in the Arab population. Data on stroke knowledge among Arabs in Israel are lacking. We aimed to examine knowledge, perceptions and thoughts of stroke among Arab-Muslim Israelis. A complementary mixed method design was used. Ninety-nine Arab Muslims living in Israel, older than 40 years, with no history of stroke, were personally interviewed. Knowledge of stroke was assessed using quantitative analysis by a semi-structured interview. Information on perceptions and thoughts evoked by stroke was analyzed using qualitative analysis by the constant comparative method. Rates of reported knowledge-related variables were presented. Mean (SD) age of participants was 50.1 (8.0) years, 52.5% were women. Most of the participants (84.8%) knew the causes of stroke but only 29.3% mentioned sudden weakness or paralysis in one side of the body as a warning sign and other warning signs were even less known. The main known risk factor was hypertension (43.3%). Although knowledge of stroke prevention was poor, 89% were interested in learning about stroke and its prevention. The qualitative findings showed that stroke evokes negative thoughts of mental and physical burden and is associated with death, disability, dependence and depression. Levels of stroke knowledge among Arab-Muslim Israelis are low to moderate. Healthcare professionals should assist high risk populations in controlling and treating risk factors in order to reduce mortality and disability following a stroke.

We investigated the effectiveness of a nurse-led intervention, where a component was to improve knowledge of prevention medications, in patients with stroke or transient ischemic attack (TIA.Methods: Prospective sub-study of the Shared Team Approach between Nurses and Doctors For Improved Risk Factor Management (STAND FIRM, a randomized controlled trial of risk factor management. We recruited patients aged ≥18 years and hospitalized for stroke/TIA. The intervention comprised an individualized management program, involving nurse-led education, and management plan with medical specialist oversight. The outcome, participants’ knowledge of secondary prevention medications at 12 months, was assessed using questionnaires. A score of ≥5 was considered as good knowledge. Effectiveness of the intervention on knowledge of medications was determined using logistic regression.

    To explore the impacts of acupuncture and rehabilitation on post-stroke abnormal patterns of limb movement and evaluate them via rehabilitation method. Ninety cases of post-stroke movement disorder were randomly divided into an acupuncture-rehabilitation group, a body acupuncture group and a medication group, 30 cases in each group. In medication group, the conventional medication in neurological department was administered. In acupuncture-rehabilitation group and body acupuncture group, on the basis of the therapy as medication group, scalp acupuncture (such as parietal area and anterior parietal area, etc.), rehabilitation training and traditional body acupuncture [such as Jianyu (LI 15) and Fengshi (GB 31),etc.] were supplemented. The continuous electric stimulation was applied in body acupuncture group. The treatment lasted for 8 weeks. The assessment of clinical efficacy, Fugl-Meyer score, Modified Ashworth scale (MAS), range of motion (ROM) and shoulder pain score were taken as observation indices for rehabilitation evaluation before and after treatment in each group. The effective rate was 93.1% (27/29) in acupuncture-rehabilitation group, which was superior to 66.7% (20/30) in body acupuncture group and 57.1% (16/28) in control group (both Prehabilitation group were significantly superior to those in body acupuncture group and medication group (Prehabilitation therapy and traditional body acupuncture remarkably improve in post-stroke movement disorder. But acupuncture and rehabilitation therapy is apparently superior to traditional body acupuncture. This therapy can effectively prevent and treat post-stroke abnormal patterns and it is greatly significant in the improvement of survival quality for the patients.

  9. Management Of Post Stroke Seizures

    Directory of Open Access Journals (Sweden)

    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

    Individuals with type-2 diabetes mellitus experience poor motor outcomes after ischemic stroke. Recent research suggests that type-2 diabetes adversely impacts neuronal integrity and function, yet little work has considered how these neuronal changes affect sensorimotor outcomes after stroke. Here, we considered how type-2 diabetes impacted the structural and metabolic function of the sensorimotor cortex after stroke using volumetric magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS). We hypothesized that the combination of chronic stroke and type-2 diabetes would negatively impact the integrity of sensorimotor cortex as compared to individuals with chronic stroke alone. Compared to stroke alone, individuals with stroke and diabetes had lower cortical thickness bilaterally in the primary somatosensory cortex, and primary and secondary motor cortices. Individuals with stroke and diabetes also showed reduced creatine levels bilaterally in the sensorimotor cortex. Contralesional primary and secondary motor cortex thicknesses were negatively related to sensorimotor outcomes in the paretic upper-limb in the stroke and diabetes group such that those with thinner primary and secondary motor cortices had better motor function. These data suggest that type-2 diabetes alters cerebral energy metabolism, and is associated with thinning of sensorimotor cortex after stroke. These factors may influence motor outcomes after stroke.

    Context: Prior researchers have examined the first-aid knowledge and decision making among high school coaches, but little is known about their perceived knowledge of exertional heat stroke (EHS) or their relationships with an athletic trainer (AT). Objective: To examine secondary school football coaches' perceived knowledge of EHS and their professional relationship with an AT. Design: Qualitative study. Setting: Web-based management system. Patients or Other Participants: Thirty-eight secondary school head football coaches (37 men, 1 woman) participated in this study. Their average age was 47 ± 10 years old, and they had 12 ± 9 years' experience as a head football coach. Data Collection and Analysis: Participants responded to a series of online questions that were focused on their perceived knowledge of EHS and professional relationships with ATs. Data credibility was established through multiple-analyst triangulation and peer review. We analyzed the data by borrowing from the principles of a general inductive approach. Results: Two dominant themes emerged from the data: perceived self-confidence of the secondary school coach and the influence of the AT. The first theme highlighted the perceived confidence, due to basic emergency care training, of the coach regarding management of an emergency situation, despite a lack of knowledge. The second theme illustrated the secondary school coach's positive professional relationships with ATs regarding patient care and emergency procedures. Of the coaches who participated, 89% (34 out of 38) indicated positive interactions with their ATs. Conclusions: These secondary school coaches were unaware of the potential causes of EHS or the symptoms associated with EHS, and they had higher perceived levels of self-confidence in management abilities than indicated by their perceived knowledge level. The secondary school football coaches valued and understood the role of the AT regarding patient and emergency care. PMID:24933433

    Full Text Available Stroke patients are at higher risk of developing cognitive impairment. Cognitive dysfunctions, especially progressive ones, worsen stroke prognosis and outcome. A longitudinal follow-up of cognitive disorders, however, is rendered difficult by their heterogeneity and the lack of definitions generally agreed upon. Stroke is a major cause of cognitive deficit. The identification of risk factors, clinical determinants and laboratory markers of post-stroke cognitive deficit may help detect patients at increased risk of cognitive deterioration, and prevent or delay the occurrence of post-stroke cognitive impairments. Though inflammatory processes have been implicated in the pathogenesis of stroke, their role in the complex pathophysiological mechanisms of post-stroke cognitive impairment is not completely understood. Evidence suggests that elevated serum C-reactive protein is associated with both the increased risk of stroke and post-stroke cognitive deficit. The hypothesis of a possible relationship between markers of systemic inflammation and cognitive dysfunctions raises the question of how rational the option of applying non-steroidal anti-inflammatory drugs in a proper therapeutic window will be, especially during the acute phase of stroke, to prevent cognitive decline and dementia.

    To examine the impact of a healthy lifestyle on stroke risk in men at higher risk of stroke because of other cardiovascular diseases or conditions. Our study population comprised 11,450 men in the Cohort of Swedish Men who had a history of hypertension, high cholesterol levels, diabetes, heart failure, or atrial fibrillation. Participants had completed a questionnaire about diet and lifestyle and were free from stroke and ischemic heart disease at baseline (January 1, 1998). We defined a healthy lifestyle as a low-risk diet (≥5 servings/d of fruits and vegetables and 0 to ≤30 g/d). Ascertainment of stroke cases was accomplished through linkage with the National Inpatient Register and the Swedish Cause of Death Register. During a mean follow-up of 9.8 years, we ascertained 1,062 incident stroke cases. The risk of total stroke and stroke types decreased with increasing number of healthy lifestyle factors. The multivariable relative risk of total stroke for men who achieved all 5 healthy lifestyle factors compared with men who achieved 0 or 1 factor was 0.28 (95% confidence interval 0.14-0.55). The corresponding relative risks (95% confidence interval) were 0.31 (0.15-0.66) for ischemic stroke and 0.32 (0.04-2.51) for hemorrhagic stroke. A healthy lifestyle is associated with a substantially reduced risk of stroke in men at higher risk of stroke. © 2015 American Academy of Neurology.

    The natural product totarol, a phenolic diterpenoid and a major constituent isolated from the sap of Podocarpus totara, has been reported to have a potent antimicrobial activity. In this study, we determined whether totarol possessed an additional neuroprotective activity in vitro and in vivo. We found that totarol prevented glutamate- and oxygen and glucose deprivation-induced neuronal death in primary rat cerebellar granule neuronal cells and cerebral cortical neurons. Totarol increased Akt and GSK-3β phosphorylation, Nrf2 and heme oxygenase-1 (HO-1) protein expressions and suppressed oxidative stress by increasing GSH and SOD activities. The PI3K/Akt inhibitor LY294002 prevented totarol neuroprotective effect by suppressing the totarol-induced changes in HO-1 expression and the activities of GSH and SOD. The HO-1 inhibitor ZnPPIX also prevented totarol-increased GSH and SOD activities. In a model of acute cerebral ischemic injury in Sprague–Dawley rats, produced by occlusion of the middle cerebral artery for 2 h followed by 22 h or 46 h of reperfusion, totarol significantly reduced infarct volume and improved the neurological deficit. In this model, totarol increased HO-1 expression and the activities of GSH and SOD. These observations suggest that totarol may be a novel activator of the Akt/HO-1 pathway protecting against ischemic stroke through reduction of oxidative stress. - Graphical abstract: It is unknown whether the natural product totarol has neuroprotective effects in vitro and in vivo. This study underscores that totarol prevents neuronal injury in vitro, not only by activating PI3K/Akt pathway, but also via induction of Nrf2, HO-1, GSH and SOD expressions. Totarol also ameliorated acute cerebral ischemic injury in a rat ischemic stroke model. The findings highlight that totarol may be exploited for protecting against ischemic stroke through Akt/HO-1 pathway. - Highlights: • Totarol protects glutamate- and OGD-induced neuronal injury in vitro.

    Sexuality plays a very significant role in the lives of both boys and girls. It is, therefore, considered important for schools to recognise and accept sexuality as part of the development process of the child. Professor Kader Asmal (previous South African Minister of Education) suggested that the earlier the school begins to teach learners about sexuality, the better because they can be easily misled by their peers if proper guidance regarding their sexuality is not given. The current study was conducted to assess the awareness of teenagers on the prevention of teenage pregnancy (TP) in six secondary school learners situated in the Soutpansberg-West circuit, Makhado Municipality in Limpopo province. The study was conducted at six secondary schools situated in the Soutpansberg-West circuit, Makhado Municipality in Limpopo province in 2014. A quantitative descriptive survey study was conducted where data were collected, using self-administered questionnaires, from 381 systematically sampled participants from six secondary schools situated in the Soutpansberg-West circuit, Makhado Municipality in Limpopo province. Data were analysed descriptively using the Statistical Package for the Social Sciences (SPSS) software, version 22.0. Necessary approval procedures and ethical clearance were obtained prior to data collection. Ninety-four percent of participants agreed that TP can be prevented through abstaining from sex, whilst 65% of participants agreed that TP could be prevented by using contraceptives such as pills and injections. Eighty-three percent of participants agreed that T Pcould be prevented through the use of condoms. Seventy-four percent participants disagreed that bathing after sex prevents teenage pregnancies. Furthermore, 28% participants agreed that TP can be prevented by oral sex. The conclusion drawn was that learners are aware of the measures for preventing TP.

    Atrial fibrillation (AF) is one of the leading causes of stroke. Risks associated with oral anticoagulation (OAC) limit adherence to recommended therapy. Left atrial appendage (LAA) occlusion is a treatment alternative in patients with AF. We performed a network meta-analysis (NMA) of randomized trials evaluating the efficacy of LAA occlusion compared with oral anticoagulant, antiplatelet, and placebo for stroke prevention. We also assessed the impact of LAA occlusion on mortality, major bleeding, and operative time. We searched MEDLINE, EMBASE, PubMed, and Cochrane Library for randomized trials comparing percutaneous or surgical LAA occlusion with standard of care in AF patients. Conventional meta-analysis found no difference between groups for stroke (5 trials, 1285 patients;RR 0.78, 95% CI 0.47-1.29), and a significant reduction in mortality (5 trials, 1285 patients; RR 0.71, 95% CI 0.51-0.99) favouring LAA occlusion. NMA demonstrated a trend towards reduction in stroke (OR 0.84, 95% CrI 0.47-1.55) and mortality (OR 0.69, 95% CrI 0.44-1.10) for LAA occlusion versus warfarin, but no statistically significant effect. Statistical ranking curves placed LAA occlusion as the most efficacious treatment on the outcomes of stroke and mortality when compared to warfarin, aspirin, or placebo. No significant differences between groups were seen in major bleeding or operative time for surgical trials. The overall quality of the evidence was low as assessed by GRADE. LAA occlusion appears to preserve the benefits of OAC therapy for stroke prevention in patients with AF, but the current evidence is of low quality.

    Full Text Available Stroke is a leading cause of mortality worldwide, as well as a source of long-term disabilities and huge socioeconomic costs. This study investigates the effects of resveratrol, an antioxidant supplement, on blood pressure, weight status, glucose, and lipid profile in patients who had a stroke in the last 12 months. Two hundred and twenty-eight patients were divided into three groups: group I received only allopathic treatment (control group, while groups II and III received allopathic treatment with a daily supplementation of oral resveratrol (100 and 200 mg, resp. for 12 months. In all groups, the changes of the studied parameters were monitored at 6 and 12 months from the initial evaluation. In groups II and III, resveratrol induced significant changes (p<0.05 in the blood pressure, body mass index, as well as all parameters of the lipid profile, and glucose (in nondiabetic patients, compared to the control group. The supplementation of the allopathic treatment with resveratrol had a beneficial effect on all monitored parameters, which serve as major risk factors for stroke.

  7. HIV, other STD, and pregnancy prevention education in public secondary schools -- 45 states, 2008-2010.

    2012-04-06

    In the United States, 46% of high school students have had sexual intercourse and potentially are at risk for human immunodeficiency virus (HIV) infection, other sexually transmitted diseases (STDs), and pregnancy. The National HIV/AIDS Strategy for the United States recommends educating young persons about HIV before they begin engaging in behaviors that place them at risk for HIV infection. The Community Preventive Services Task Force (CPSTF) also recommends risk reduction interventions to prevent HIV, other STDs, and pregnancy among adolescents. To estimate changes in the percentage of secondary schools that teach specific HIV, other STD, and pregnancy risk reduction topics, a key intervention consistent with those supported by the National HIV/AIDS Strategy and CPSTF, CDC analyzed 2008 and 2010 School Health Profiles data for public secondary schools in 45 states. This report summarizes the results of those analyses, which indicated that in 2010, compared with 2008, the percentage of secondary schools teaching 11 topics on HIV, other STD, and pregnancy prevention in a required course in grades 6, 7, or 8 was significantly lower in 11 states and significantly higher in none; the percentage of secondary schools teaching eight topics in a required course in grades 9, 10, 11, or 12 was significantly lower in one state and significantly higher in two states; and the percentage of secondary schools teaching three condom-related topics in a required course in grades 9, 10, 11, or 12 was significantly lower in eight states and significantly higher in three states. Secondary schools can increase efforts to teach all age-appropriate HIV, other STD, and pregnancy prevention topics to help reduce risk behaviors among students.

    Background Stroke is a common cause of cognitive impairment and dementia. However, effective strategies for reducing the risk of post-stroke dementia remain undefined. Potential strategies include intensive lowering of blood pressure and/or lipids. Methods/Design Design: multi-centre prospective randomised open-label blinded-endpoint controlled partial-factorial phase IV trial in secondary and primary care. Participants: 100 participants from 30 UK Stroke Research Network sites who are post- ischemic stroke or intracerebral haemorrhage by three to seven months. Interventions - all patients (1:1): intensive versus guideline blood pressure lowering (target systolic cognitive decline and dementia in people with ischemic stroke; and does ‘intensive’ blood pressure lowering therapy reduce cognitive decline and dementia in patients with hemorrhagic stroke. Primary outcome: Addenbrooke’s Cognitive Examination-Revised. Secondary outcomes: feasibility of recruitment and retention of participants, tolerability and safety of the interventions, achieving and maintaining the blood pressure and lipid targets, maintaining differences in systolic blood pressure (> 10 mmHg) and low density lipoprotein-cholesterol (> 1 mmol/l) between the treatment groups, and performing clinic and telephone follow-up of cognition measures. Randomisation: using stratification, minimization and simple randomization. Blinding: participants receive open-label management. Cognition is assessed both unblinded (in clinic) and blinded (by telephone) to treatment. Adjudication of events (dementia, vascular, serious adverse events) is blinded to management. Discussion The PODCAST trial is ongoing with 78 patients recruited to date from 22 sites. Outcomes of cognitive impairment and dementia are accruing. Trial registration ISRCTN85562386 PMID:24266960

    Osteoporosis is a major public health concern affecting an estimated 10 million people in the United States. To the best of our knowledge, no qualitative study has explored barriers perceived by medicine hospitalists to secondary prevention of osteoporotic hip fractures. We aimed to describe these perceived barriers and recommendations regarding how to optimize secondary prevention of osteoporotic hip fracture. In-depth, semistructured interviews were performed with 15 internal medicine hospitalists in a tertiary-care referral medical center. The interviews were analyzed with directed content analysis. Internal medicine hospitalists consider secondary osteoporotic hip fracture prevention as the responsibility of outpatient physicians. Identified barriers were stratified based on themes including physicians' perception, patients' characteristics, risks and benefits of osteoporosis treatment, healthcare delivery system, and patient care transition from the inpatient to the outpatient setting. Some of the recommendations include building an integrated system that involves a multidisciplinary team such as the fracture liaison service, initiating a change to the hospital policy to facilitate inpatient care and management of osteoporosis, and creating a smooth patient care transition to the outpatient setting. Our study highlighted how internal medicine hospitalists perceive their role in the secondary prevention of osteoporotic hip fractures and what they perceive as barriers to initiating preventive measures in the hospital. Inconsistency in patient care transition and the fragmented nature of the existing healthcare system were identified as major barriers. A fracture liaison service could remove some of these barriers.

    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.

  11. Regulatory T Cells in Post-stroke Immune Homeostasis.

    2016-08-01

    The secondary neuroinflammatory response has come into focus of experimental stroke research. Immunological mechanisms after acute stroke are being investigated in the hope to identify novel and druggable pathways that contribute to secondary infarct growth after stroke. Among a variety of neuroimmunological events after acute brain ischemia, including microglial activation, brain leukocyte invasion, and secretion of pro-inflammatory factors, lymphocytes have been identified as the key leukocyte subpopulation driving the neuroinflammatory response and contributing to stroke outcome. Several studies have shown that pro-inflammatory lymphocyte subpopulations worsen stroke outcome and that inhibiting their invasion to the injured brain is neuroprotective. In contrast to the effector functions of pro-inflammatory lymphocytes, regulatory T cells (Treg) are critically involved in maintaining immune homeostasis and have been characterized as disease-limiting protective cells in several inflammatory conditions, particularly in primary inflammatory diseases of the central nervous system (CNS). However, due to the complex function of regulatory cells in immune homeostasis and disease, divergent findings have been described for the role of Treg in stroke models. Emerging evidence suggests that this discrepancy arises from potentially differing functions of Treg depending on the predominant site of action within the neurovascular unit and the surrounding inflammatory milieu. This article will provide a comprehensive review of current findings on Treg in brain ischemia models and discuss potential reasons for the observed discrepancies.

    A cerebral artery infarction is an important differential diagnosis in the newborn with neurological abnormalities. Based on clinical data, its incidence is estimated to be 1 in 4000 newborns. Since the course is often subclinical, the true incidence is probably higher. Diagnosis: Cerebral ultrasound and Doppler sonography as readily available screening tools play a central role in the initial diagnosis of neonatal cerebral infarction. Definitive diagnosis is made by computed tomography or magnetic resonance imaging. Beside symptomatic anticonvulsive therapy, treatment aims at the prevention of secondary ischemic injury. Discussion: Three term infants with different clinical courses of neonatal stroke are presented to sensitize the clinician and the radiologist for this probably underdiagnosed entity. The role of imaging modalities in the diagnosis and follow-up of neonatal cerebral infarction is discussed. (orig.) [German] Ein Infarkt im Stromgebiet der Zerebralarterien stellt eine wichtige Differentialdiagnose bei neurologischen Auffaelligkeiten in der Neonatalperiode dar. Die Inzidenz wird anhand von klinischer Daten auf 1:4000 Lebendgeborene geschaetzt. Da der Verlauf oft subklinisch ist, liegt die wahre Inzidenz wahrscheinlich hoeher. Diagnose: Bei der Diagnosestellung kommen dem Schaedelultraschall und der Doppelsonographie als leicht verfuegbaren Screening-Methoden eine zentrale Rolle zu. Die definitive Diagnose wird, je nach Verfuegbarkeit, mittels Computertomographie oder Kernspintomographie gestellt. Die Behandlung ist neben der symptomatischen (antikonvulsiven) Therapie auf die Vermeidung von ischaemischen Sekundaerschaeden gerichtet. Diskussion: Wir wollen mit der vorliegenden Arbeit anhand von 3 Kindern mit verschiedenen klinischen Verlaeufen eines sog.

    Secondary growth is driven by continuous cell proliferation and differentiation of the cambium that acts as vascular stem cells, producing xylem and phloem to expand vascular tissues laterally. During secondary growth of hypocotyls in Arabidopsis thaliana, the xylem undergoes a drastic phase transition from a parenchyma-producing phase to a fiber-producing phase at the appropriate time. However, it remains to be fully elucidated how progression of secondary growth is properly controlled. We focused on phenotypes of hypocotyl vasculatures caused by double mutation in ERECTA (ER) and ER-LIKE1 (ERL1) receptor-kinase genes to elucidate their roles in secondary growth. ER and ERL1 redundantly suppressed excessive radial growth of the hypocotyl vasculature during secondary growth. ER and ERL1 also prevented premature initiation of the fiber differentiation process mediated by the NAC SECONDARY WALL THICKENING PROMOTING FACTORs in the hypocotyl xylem. Upon floral transition, the hypocotyl xylem gained a competency to respond to GA in a BREVIPEDICELLUS-dependent manner, which was a prerequisite for fiber differentiation. However, even after the floral transition, ER and ERL1 prevented precocious initiation of the GA-mediated fiber formation. Collectively, our findings reveal that ER and ERL1 redundantly prevent premature progression of sequential events in secondary growth. © 2016 The Authors.

    2015-01-01

    Background Stroke survivors represent a target population in need of intervention strategies to promote cognitive function and prevent dementia. Both exercise and recreational activities are promising strategies. We assessed the effect of a six-month exercise and recreation program on executive functions in adults with chronic stroke. Methods A six-month ancillary study within a multi-centre randomized trial. Twenty-eight chronic stroke survivors (i.e., ≥ 12 months since an index stroke) were randomized to one of two experimental groups: intervention (INT; n=12) or delayed intervention (D-INT; n=16). Participants of the INT group received a six-month community-based structured program that included two sessions of exercise training and one session of recreation and leisure activities per week. Participants of the D-INT group received usual care. The primary outcome measure was the Stroop Test, a cognitive test of selective attention and conflict resolution. Secondary cognitive measures included set shifting and working memory. Mood, functional capacity, and general balance and mobility were additional secondary outcome measures. Results Compared with the D-INT group, the INT group significantly improved selective attention and conflict resolution (p=0.02), working memory (p=0.04), and functional capacity (p=0.02) at the end of the six-month intervention period. Improved selective attention and conflict resolution was significantly associated with functional capacity at six months (r=0.39; p=0.04). Conclusions This is the first randomized study to demonstrate that an exercise and recreation program can significantly benefit executive functions in community-dwelling chronic stroke survivors who are mildly cognitively impaired – a population at high-risk for dementia and functional decline. Thus, clinicians should consider prescribing exercise and recreational activities in the cognitive rehabilitation of chronic stroke survivors. Clinical Trial Registration http

    Outpatient statin use reduces the risk of recurrent ischemic stroke among patients with stroke of atherothrombotic cause. It is not known whether statins have similar effects in ischemic stroke caused by atrial fibrillation (AFib). We studied outpatient statin adherence, measured by percentage of days covered, and the risk of recurrent ischemic stroke in patients with or without AFib in a 21-hospital integrated healthcare delivery system. Among 6116 patients with ischemic stroke discharged on a statin over a 5-year period, 1446 (23.6%) had a diagnosis of AFib at discharge. The mean statin adherence rate (percentage of days covered) was 85, and higher levels of percentage of days covered correlated with greater degrees of low-density lipoprotein suppression. In multivariable survival models of recurrent ischemic stroke over 3 years, after controlling for age, sex, race/ethnicity, medical comorbidities, and hospital center, higher statin adherence predicted reduced stroke risk both in patients without AFib (hazard ratio, 0.78; 95% confidence interval, 0.63-0.97) and in patients with AFib (hazard ratio, 0.59; 95% confidence interval, 0.43-0.81). This association was robust to adjustment for the time in the therapeutic range for international normalized ratio among AFib subjects taking warfarin (hazard ratio, 0.61; 95% confidence interval, 0.41-0.89). The relationship between statin adherence and reduced recurrent stroke risk is as strong among patients with AFib as it is among patients without AFib, suggesting that AFib status should not be a reason to exclude patients from secondary stroke prevention with a statin. © 2017 American Heart Association, Inc.

    Rationale The utility of patent foramen ovale (PFO) closure for secondary prevention in patients with prior cryptogenic stroke is uncertain despite multiple randomized trials completed to date. Aims The Gore REDUCE Clinical Study (REDUCE) aims to establish superiority of patent foramen ovale closure in conjunction with antiplatelet therapy over antiplatelet therapy alone in reducing the risk of recurrent clinical ischemic stroke or new silent brain infarct in patients who have had a cryptogenic stroke. Methods and design This controlled, open-label trial randomized 664 subjects with cryptogenic stroke at 63 multinational sites in a 2:1 ratio to either antiplatelet therapy plus patent foramen ovale closure (with GORE® HELEX® Septal Occluder or GORE® CARDIOFORM Septal Occluder) or antiplatelet therapy alone. Subjects will be prospectively followed for up to five years. Neuroimaging is required for all subjects at baseline and at two years or study exit. Study outcomes The two co-primary endpoints for the study are freedom from recurrent clinical ischemic stroke through at least 24 months post-randomization and incidence of new brain infarct (defined as clinical ischemic stroke or silent brain infarct) through 24 months. The primary analyses are an unadjusted log-rank test and a binomial test of subject-based proportions, respectively, both on the intent-to-treat population, with adjustment for testing multiplicity. Discussion The REDUCE trial aims to target a patient population with truly cryptogenic strokes. Medical therapy is limited to antiplatelet agents in both arms thereby reducing confounding. The trial should determine whether patent foramen ovale closure with the Gore septal occluders is safe and more effective than medical therapy alone for the prevention of recurrent clinical ischemic stroke or new silent brain infarct; the neuroimaging data will provide an opportunity to further support the proof of concept. The main results are anticipated in 2017

    Our aim was to evaluate the diagnostic yield of transesophageal echocardiography (TEE) in consecutive patients with ischemic stroke (IS) fulfilling the diagnostic criteria of embolic strokes of undetermined source (ESUS). We prospectively evaluated consecutive patients with acute IS satisfying ESUS criteria who underwent in-hospital TEE examination in 3 tertiary care stroke centers during a 12-month period. We also performed a systematic review and meta-analysis estimating the cumulative effect of TEE findings on therapeutic management for secondary stroke prevention among different IS subgroups. We identified 61 patients with ESUS who underwent investigation with TEE (mean age 44 ± 12 years, 49% men, median NIH Stroke Scale score = 5 points [interquartile range: 3-8]). TEE revealed additional findings in 52% (95% confidence interval [CI]: 40%-65%) of the study population. TEE findings changed management (initiation of anticoagulation therapy, administration of IV antibiotic therapy, and patent foramen ovale closure) in 10 (16% [95% CI: 9%-28%]) patients. The pooled rate of reported anticoagulation therapy attributed to abnormal TEE findings among 3,562 acute IS patients included in the meta-analysis (12 studies) was 8.7% (95% CI: 7.3%-10.4%). In subgroup analysis, the rates of initiation of anticoagulation therapy on the basis of TEE investigation did not differ (p = 0.315) among patients with cryptogenic stroke (6.9% [95% CI: 4.9%-9.6%]), ESUS (8.1% [95% CI: 3.4%-18.1%]), and IS (9.4% [95% CI: 7.5%-11.8%]). Abnormal TEE findings may decisively affect the selection of appropriate therapeutic strategy in approximately 1 of 7 patients with ESUS. © 2016 American Academy of Neurology.

    Background The aim of the study was to measure knowledge about the symptoms, prevalence and natural history of stroke; the level of concern about having a stroke; understanding of the possibilities for preventing stroke, and the relationship between age, sex, country of origin, educational level, income, self-reported risk factors, and the above factors. Methods A random sample of households was selected from an electronic telephone directory in Newcastle and Lake Macquarie area of New South Wales, Australia, between 10 September and 13 October 1999. Within each household the person who was between 18 and 80 years of age and who had the next birthday was eligible to participate in the study (1325 households were eligible). The response rate was 62%. Results The most common symptoms of stroke listed by respondents were "Sudden difficulty of speaking, understanding or reading" identified by 60.1% of the respondents, and "paralysis on one side of body" identified by 42.0% of the respondents. The level of knowledge of the prevalence of a stroke, full recovery after the stroke, and death from stroke was low and generally overestimated. 69.9% of the respondents considered strokes as being either moderately or totally preventable. There were few predictors of knowledge. Conclusion The study suggests that educational strategies may be required to improve knowledge about a wide range of issues concerning stroke in the community, as a prelude to developing preventive programmes.

    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.

    A century after its discovery, Chagas' disease still represents a major public health challenge in Latin America. Moreover, because of growing population movements, an increasing number of cases of imported Chagas' disease have now been detected in non-endemic areas, such as North America and some European countries. This parasitic zoonosis, caused by Trypanosoma cruzi, is transmitted to humans by infected Triatominae insects, or occasionally by non-vectorial mechanisms, such as blood transfusion, mother to fetus, or oral ingestion of materials contaminated with parasites. Following the acute phase of the infection, untreated individuals enter a chronic phase that is initially asymptomatic or clinically unapparent. Usually, a few decades later, 40-50% of patients develop progressive cardiomyopathy and/or motility disturbances of the oesophagus and colon. In the last decades several interventions targeting primary, secondary and tertiary prevention of Chagas' disease have been attempted. While control of both vectorial and blood transfusion transmission of T cruzi (primary prevention) has been successful in many regions of Latin America, early detection and aetiological treatment of asymptomatic subjects with Chagas' disease (secondary prevention) have been largely underutilised. At the same time, in patients with established chronic disease, several pharmacological and non-pharmacological interventions are currently available and have been increasingly used with the intention of preventing or delaying complications of the disease (tertiary prevention). In this review we discuss in detail each of these issues.

    Stroke in the young has not been thoroughly investigated with most previous studies based on a small number of patients from single centers. Furthermore, recent reports indicate that Fabry disease may be a significant cause for young stroke. The primary aim of our study was to determine the prevalence of Fabry disease in young stroke patients, while the secondary aim was to describe patterns of stroke in young patients.

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.

    Two thirds of the global mortality of stroke is borne by low and middle income countries (LMICs). Pakistan is the world's sixth most populous country with a stroke-vulnerable population and is without a single dedicated chronic care center. In order to provide evidence for a viable solution responsive to this health care gap, and leveraging the existing >70% mobile phone density, we thought it rational to test the effectiveness of a mobile phone-based video intervention of short 5-minute movies to educate and support stroke survivors and their primary caregivers. Movies4Stroke will be a randomized control, outcome assessor blinded, parallel group, single center superiority trial. Participants with an acute stroke, medically stable, with mild to moderate disability and having a stable primary caregiver will be included. After obtaining informed consent the stroke survivor-caregiver dyad will be randomized. Intervention participants will have the movie program software installed in their phone, desktop, or Android device which will allow them to receive, view and repeat 5-minute videos on stroke-related topics at admission, discharge and first and third months after enrollment. The control arm will receive standard of care at an internationally accredited center with defined protocols. The primary outcome measure is medication adherence as ascertained by a locally validated Morisky Medication Adherence Scale and control of major risk factors such as blood pressure, blood sugar and blood cholesterol at 12 months post discharge. Secondary outcome measures are post-stroke complications and mortality, caregiver knowledge and change in functional outcomes after acute stroke at 1, 3, 6, 9 and 12 months. Movies4Stroke is designed to enroll 300 participant dyads after inflating 10% to incorporate attrition and non-compliance and has been powered at 95% to detect a 15% difference between intervention and usual care arm. Analysis will be done by the intention

    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

    A workshop was held September 27 through 29, 1999, to address issues relating to national trends in mortality and morbidity from cardiovascular diseases; the apparent slowing of declines in mortality from cardiovascular diseases; levels and trends in risk factors for cardiovascular diseases; disparities in cardiovascular diseases by race/ethnicity, socioeconomic status, and geography; trends in cardiovascular disease preventive and treatment services; and strategies for efforts to reduce cardiovascular diseases overall and to reduce disparities among subpopulations. The conference concluded that coronary heart disease mortality is still declining in the United States as a whole, although perhaps at a slower rate than in the 1980s; that stroke mortality rates have declined little, if at all, since 1990; and that there are striking differences in cardiovascular death rates by race/ethnicity, socioeconomic status, and geography. Trends in risk factors are consistent with a slowing of the decline in mortality; there has been little recent progress in risk factors such as smoking, physical inactivity, and hypertension control. There are increasing levels of obesity and type 2 diabetes, with major differences among subpopulations. There is considerable activity in population-wide prevention, primary prevention for higher risk people, and secondary prevention, but wide disparities exist among groups on the basis of socioeconomic status and geography, pointing to major gaps in efforts to use available, proven approaches to control cardiovascular diseases. Recommendations for strategies to attain the year 2010 health objectives were made.

  12. Cost effectiveness of novel oral anticoagulants for stroke prevention in atrial fibrillation depending on the quality of warfarin anticoagulation control.

    Vitamin K antagonists, such as warfarin, are standard treatments for stroke prophylaxis in patients with atrial fibrillation. Patient outcomes depend on quality of warfarin management, which includes regular monitoring and dose adjustments. Recently, novel oral anticoagulants (NOACs) that do not require regular monitoring offer an alternative to warfarin. The aim of this study was to evaluate whether cost effectiveness of NOACs for stroke prevention in atrial fibrillation depends on the quality of warfarin control. We developed a Markov decision model to simulate warfarin treatment outcomes in relation to the quality of anticoagulation control, expressed as percentage of time in the therapeutic range (TTR). Standard treatment with adjusted-dose warfarin and improved anticoagulation control by genotype-guided dosing were compared with dabigatran, rivaroxaban, apixaban and edoxaban. The analysis was performed from the Slovenian healthcare payer perspective using 2014 costs. In the base case, the incremental cost-effectiveness ratio for apixaban, dabigatran and edoxaban was below the threshold of €25,000 per quality-adjusted life-years compared with adjusted-dose warfarin with a TTR of 60%. The probability that warfarin was a cost-effective option was around 1%. This percentage rises as the quality of anticoagulation control improves. At a TTR of 70%, warfarin was the preferred treatment in half the iterations. The cost effectiveness of NOACs for stroke prevention in patients with nonvalvular atrial fibrillation who are at increased risk for stroke is highly sensitive to warfarin anticoagulation control. NOACs are more likely to be cost-effective options in settings with poor warfarin management than in settings with better anticoagulation control, where they may not represent good value for money.

    There is wanting data regarding young ischemic stroke in developing countries, especially in Tunisia. The purpose of this study was to investigate risk factors and etiologies of young ischemic stroke in Tunisian and make a comparison with previous reports. A total of 102 young ischemic stroke patients (15-45 years old) were admitted, between January 1996 and August 2007, to 11 departments of internal medicine in different Tunisian hospitals. The risk factors for stroke were documented and assessed. Diagnosis workup consisted of anamnesis, complete physical examination and extensive laboratory, radiologic, immunologic, neurologic and cardiologic examination. Stroke etiologies were classified according the Trial of ORG 10172 in acute stroke treatment. There were 42 men (41.2%) and 60 women (58.89%) with a mean age at onset of 35.7 years. As regards stroke subtype, large-artery atherosclerosis was diagnosed in 6.9% of cases, cardioembolism in 11.8%, small-vessel occlusion in 8.8%, other determined etiology in 37.3% and undetermined etiology in 35.3%. Concerning the traditional risk factors, smoking (31.4%), hypertension and diabetes mellitus (12.7% for each one) and a family history of stroke (10.8%) were the most common. The mean follow-up period was 30.5 months. In our study, traditional risk factors were not-so-uncommon in young adults with ischemic stroke suggesting that prevention can go through controlling these factors. Stroke of other determined etiology was the most common among our patients, so that a broad and detailed diagnostic workup is crucial to puzzle out the etiology for more and better stroke prevention.

    Full Text Available Introduction: Non-invasive, continuous hemodynamic monitoring is entering the clinical arena. The primary objective of this study was to test the feasibility of such monitoring in a pilot sample of Emergency Department (ED stroke patients. Secondary objectives included analysis of hemodynamic variability and correlation of continuous blood pressure measurements with standard measurements. Methods: This study was a secondary analysis of 7 stroke patients from a prospectively collected data set of patients that received 2 hours of hemodynamic monitoring in the ED. Stroke patients were included if hemorrhagic or ischemic stroke was confirmed by neuroimaging, and symptom onset was within 24 hours. They were excluded for the presence of a stroke mimic or transient ischemic attack. Monitoring was performed using the Nexfin device (Edwards Lifesciences, Irvine CA. Results: The mean age of the cohort was 71 ± 17 years, 43% were male, and the mean National Institute of Health Stroke Scale (NIHSS was 6.9 ± 5.5. Two patients had hemorrhagic stroke. We obtained 42,456 hemodynamic data points, including beat-to-beat blood pressure measurements with variability of 18 mmHg and cardiac indices ranging from 1.8 to 3.6 l/min/m2. The correlation coefficient between continuous blood pressure measurements with the Nexfin device and standard ED readings was 0.83. Conclusion: This exploratory investigation revealed that continuous, noninvasive monitoring in the ED is feasible in acute stroke. Further research is currently underway to determine how such monitoring may impact outcomes in stroke or replace the need for invasive monitoring. [West J Emerg Med. 2014;15(4:–0.

    Routinely fasting is not necessary for measuring the lipid profile according to the latest European consensus. However, LDL-C tends to be lower in the non-fasting state with risk of misclassification. The extent of misclassification in secondary cardiovascular prevention with a non-fasting lipid profile was investigated. 329 patients on lipid lowering therapy for secondary cardiovascular prevention measured a fasting and non-fasting lipid profile. Cut-off values for LDL-C, non-HDL-C and apolipoprotein B were set at fasting LDL-C (calculated using the Friedewald formula), direct LDL-C, non-HDL-C and apolipoprotein B. Net misclassification fasting measurements resulted in lower LDL-C (-0.2±0.4mmol/l, Pfasting LDL-C target of fasting state. In the non-fasting state net misclassification with direct LDL-C was 5.7% (95% CI 2.1-9.2%), 4.0% (95% CI 1.0-7.4%) with non-HDL-C and 4.1% (95% CI 1.1-9.1%) with apolipoprotein B. Use of non-fasting LDL-C as treatment target in secondary cardiovascular prevention resulted in significant misclassification with subsequent risk of undertreatment, whereas non-fasting direct LDL-C, non-HDL-C and apolipoprotein B are reliable parameters.

    Qatar is located on the northeastern coast of the Arabian Peninsula. The total population is over 2.1 million with around 15% being Qatari citizens. Hamad General Hospital (HGH) is the only tertiary referral governmental hospital in Qatar which admits acute (thrombolysis-eligible) stroke patients. To provide an overview of the burden of stroke in Qatar. Data from literature databases, online sources and our stroke registry were collated to identify information on the burden of stroke in Qatar. Overall, over 80% of all stroke patients in Qatar are admitted in HGH. In 2010, the age-standardized incidence for first-ever ischemic stroke was 51.88/100,000 person-years. To date our stroke registry reveals that 79% of all stroke patients are male and almost 50% of stroke patients are 50 years or less. Hypertension, diabetes and dyslipidemia are the main predisposing factors for stroke, with ischemic stroke being more common (87%) than hemorrhagic stroke (13%). Despite the lack of a stroke unit, 9% of ischemic stroke patients are being thrombolyzed. However the presence of a stroke ward allows swift turnover of patients with a length of stay of less than 5 days before discharge or, if required, transfer to the fully-equipped hospital-based rehabilitation service. Several community awareness programs are ongoing, in addition to several research programs funded by the Qatar National Research Fund and Hamad Medical Corporation. In a country where over 15% of the population suffers from diabetes there is continuous need for national community-based awareness campaigns, prevention and educational programs particularly targeting patients and health care workers.

    2015-01-01

    The field of Alzheimer disease (AD) prevention has been a culmination of basic science, clinical, and translational research. In the past three years since the new 2011 AD diagnostic guidelines, large-scale collaborative efforts have embarked on new clinical trials with the hope of someday preventing AD. This review will shed light on the historical and scientific contexts in which these trials were based on, as well as discuss potential challenges these trials may face in the coming years. Primary preventive measures, such as lifestyle, multidomain, medication, and supplemental interventions, will be analyzed. Secondary prevention as represented by disease-modifying interventions, such as anti-amyloid therapy and pioglitazone, will also be reviewed. Finally, hypotheses on future directions for AD prevention trials will be proposed. PMID:27697063

    Full Text Available Stroke is associated with the development of cognitive impairment and dementia. We assessed the effect of intensive blood pressure (BP and/or lipid lowering on cognitive outcomes in patients with recent stroke in a pilot trial.In a multicentre, partial-factorial trial, patients with recent stroke, absence of dementia, and systolic BP (SBP 125-170 mmHg were assigned randomly to at least 6 months of intensive (target SBP <125 mmHg or guideline (target SBP <140 mmHg BP lowering. The subset of patients with ischaemic stroke and total cholesterol 3.0-8.0 mmol/l were also assigned randomly to intensive (target LDL-cholesterol <1.3 mmol/l or guideline (target LDL-c <3.0 mmol/l lipid lowering. The primary outcome was the Addenbrooke's Cognitive Examination-Revised (ACE-R.We enrolled 83 patients, mean age 74.0 (6.8 years, and median 4.5 months after stroke. The median follow-up was 24 months (range 1-48. Mean BP was significantly reduced with intensive compared to guideline treatment (difference -10·6/-5·5 mmHg; p<0·01, as was total/LDL-cholesterol with intensive lipid lowering compared to guideline (difference -0·54/-0·44 mmol/l; p<0·01. The ACE-R score during treatment did not differ for either treatment comparison; mean difference for BP lowering -3.6 (95% CI -9.7 to 2.4, and lipid lowering 4.4 (95% CI -2.1 to 10.9. However, intensive lipid lowering therapy was significantly associated with improved scores for ACE-R at 6 months, trail making A, modified Rankin Scale and Euro-Qol Visual Analogue Scale. There was no difference in rates of dementia or serious adverse events for either comparison.In patients with recent stroke and normal cognition, intensive BP and lipid lowering were feasible and safe, but did not alter cognition over two years. The association between intensive lipid lowering and improved scores for some secondary outcomes suggests further trials are warranted.ISRCTN ISRCTN85562386.

    Inconsistent evidence supports better outcome in smokers after stroke. Our study examines this association in a large sample of ischemic stroke treated with intravenous thrombolysis. Virtual International Stroke Trials Archive (VISTA) database, composed of individual patient data of multiple clinical trials, was queried. The primary outcome was functional independence at 3 months noted by modified Rankin Scale (mRS; a 7-point scale ranging from 0 [no deficit] to 6 [death]) score≤ 2. The secondary outcomes were National Institutes of Health Stroke Scale (NIHSS; stroke severity measure, ranging from 0 [no deficit] to 42 [most severe]) score at 24 hours and the occurrence of symptomatic intractracranial hemorrhage. A total of 5383 patients were included: 1501 current smokers and 3882 nonsmokers. Smokers were younger (60 ± 13 vs. 71 ± 12 years, p vs. 13 [9-18], p smokers (49.7% vs. 39.5%, p non-significant after adjusting for age (OR 1.11, 95% CI 0.97-1.27). Subgroup analysis by age/gender strata showed that current smoking was associated with favorable outcome only in women ≥ 65 years. Current smoking was also associated with lower rates of symptomatic intracranial hemorrhage (adjusted OR 0.55, 95% CI 0.39-0.79). Smokers experience their first ever stroke 11 years younger than nonsmokers. This age difference explains the association between current smoking and favorable functional outcome. Smoking is associated with occurrence of first ever stroke at a younger age, therefore, focus should be on smoking prevention and treatment. The decision to treat ischemic stroke patients with intravenous thrombolysis should not be influenced by the patients' smoking status. © The Author 2017.

    Full Text Available Stroke is the leading cause of death in every hospital in Indonesia. The death rate of newly formed or recurrent stroke is estimated around 750.000 case every year nation wide, 200.000 of which are recurrent stroke. Stroke patients have higher risk to develop another stroke attack. In 5 years time, the recurrence of stroke attack is estimated around 30–43%. In many cases, elderly stroke patients who were admitted to the hospital with recurrent stroke attack also suffer from anorexia which leads to hypoalbuminemia, hyponatremia, hypokalemia and impaired renal function marked by a rise in ureum level with or without elevation in blood creatinin levels. This study uses pre and post nutrition intervention method. Hospital’s fermented soybean cake and albumin blend formula was given through nasogastric tube. The amount of calorie was adjusted according to basal needs x 1,3 and consisted of carbohydrate, protein 1 gram/kg BB (albumin : fermented soybean cake=3:1 and 25% fat. This formula was given to 11 stroke patients who had been admitted to Atma Jaya Hospital for at least 10 days and met the inclusion & exclusion criteria, such as did not receive parenteral blood and albumin transfusion without history of renal failure. All the patients’ intake and fluid balance were monitored. The average albumin level of these patients was ±3,1 mg/dL(pre intervention. After receiving nutrition (NGT and fluid (parenteral nutrition intervention, the result is as follows: There was an average of±5 mg increase in Natrium level during day 3–5 of hospital stay. There was an average of±0,3 mg increase in Kalium level during day 2–3 of hospital stay. There was an average of ±15 mg reduction of Ureum level during day 5–7 of hospital stay When there was inadequate calorie intake, protein from muscle might be broken down marked by a rise in blood ureum level with or without an increase in creatinin level.

    Full Text Available Ischemic mechanisms in patients with brain and heart attacks have been studied for more than 150 years. Antiplatelets agents did show benefit in secondary prevention. Aspirin is the most common antiaggregant in clinical use today. However, the benefit produced by the "best" antiplatelet regimen in stroke prevention is lower than 40%. The adherence of circulating platelets to the subendothelium is mediated by glycoprotein (GP residing on the cell's surface. GPIIb/IIIa is the most important platelet membrane receptor that mediates the process of platelet aggregation, and thrombus formation. Thus, new drugs that block the GPIIb/IIIa receptor have recently emerged. Clinical trials using these agents have shown effectiveness in acute coronary syndromes. However, the absence of studies in cerebrovascular disease and the potential hemorrhagic complications questioned their use in stroke prevention. We review the clinical trials using the new GPIIb/IIIa agents in myocardial ischemia, and consider the potential implications for cerebrovascular disease.Los mecanismos de isquemia en infarto de miocardio y enfermedad cerebrovascular (ECV han sido estudiados por mas de 150 años. Drogas antiplaquetarias mostraron un beneficio en la prevención secundaria. La aspirina es el mas común de los antiagregantes usados en la practica clínica. No obstante, el beneficio producido, aun con el "mejor" tratamiento antiagregante, en la prevención de ECV es inferior al 40%. La adhesión plaquetaria es un proceso mediado por glicoproteinas (GP de la membrana celular. GPIIb/IIIa es un receptor de membrana plaquetaria que interviene en el proceso de agregación plaquetaria y formación del trombo. Estudios clínicos con nuevos agentes que bloquean a este receptor mostraron ser efectivos en los síndromes coronarios agudos. No obstante, la falta de estudios en ECV y las potenciales complicaciones hemorrágicas, limitan su uso en la prevención de stroke. Revisamos los

    Rapid management can reduce the short stroke risk after transient ischaemic attack (TIA), but the long-term effect is still little known. We evaluated 3-year vascular outcomes in patients with TIA after urgent care. We prospectively enrolled all consecutive patients with TIA diagnosed by a vascular neurologist and referred to our emergency department (ED). Expedited assessment and best secondary prevention was within 24 h. Endpoints were stroke within 90 days, and stroke, myocardial infarction, and vascular death at 12, 24 and 36 months. Between August 2010 and July 2013, we evaluated 686 patients with suspected TIA; 433 (63%) patients had confirmed TIA. Stroke at 90 days was 2.07% (95% confidence interval (CI), 1.1-3.9) compared with the ABCD2-predicted risk of 9.1%. The long-term stroke risk was 2.6% (95% CI, 1.1-4.2), 3.7% (95% CI, 1.6-5.9) and 4.4% (95% CI, 1.9-6.8) at 12, 24 and 36 months, respectively. The composite outcome of stroke, myocardial infarction, and vascular death was 3.5% (95% CI, 1.7-5.1), 4.9% (95% CI, 2.5-7.4), and 5.6% (95% CI, 2.8-8.3) at 12, 24, and 36 months, respectively. TIA expedited management driven by vascular neurologists was associated with a marked reduction in the expected early stroke risk and low long-term risk of stroke and other vascular events. © 2015 S.

    Post-traumatic stress disorder (PTSD) is unique amongst psychiatric disorders in two ways. Firstly, there is usually a very clear point of onset- the traumatic event The second unique feature of PTSD is that it is characterized by a failure of the normal response to resolve. Given these two characteristics, PTSD appears a good candidate for secondary prevention, ie, interventions immediately after the trauma. Evidence available starting from current concepts and contemporary research of potential secondary prevention interventions are presented. Common practices in the aftermath of trauma such as debriefing and benzodiazepines need to be carefully considered, taking into account their potential harm to the spontaneous recovery process, and the trajectory of PTSD, and not only judging them according to their immediate (comforting) effects. A discussion of the balance required between aiding recovery but not interfering with the potent natural resolution of symptoms (that is expected in most cases), along with potential avenues of future research, are presented. Results of a small pilot study with a single intervention of hydrocortisone immediately after trauma appear to be promising, and clearly indicate the need for further studies. PMID:22033784

    "Get With The Guidelines (GWTG)" was developed and piloted by the American Heart Association (AHA), New England Affiliate; MassPRO, Inc.; and other organizations to reduce the gap in the application of secondary prevention guidelines in hospitalized cardiovascular disease patients. Collaborative learning programs and technology solutions were created for the project. The interactive Web-based patient management tool (PMT) was developed using quality measures derived from the AHA/American College of Cardiology secondary prevention guidelines. It provided data entry, embedded reminders and guideline summaries, and online reports of quality measure performance, including comparisons with the aggregate performance of all hospitals. Multidisciplinary teams from 24 hospitals participated in the 2000-2001 pilot. Four collaborative learning sessions and monthly conference calls supported team interaction. Best-practices sharing and the use of an Internet tool enabled hospitals to change systems and collect data on 1,738 patients. The GWTG program, a template of learning sessions with didactic presentations, best-practices sharing, and collaborative multidisciplinary team meetings supported by the Internet-based data collection and reporting system, can be extended to multiple regions without requiring additional development. Following the completion of the pilot, the AHA adopted GWTG as a national program.

    To investigate the correlations of atheromatous plaques in the aortic arch or supra-aortic arteries with intracranial arterial stenosis and carotid plaques in stroke patients, and to determine whether taking these plaques into account will reduce the proportion of patients in the undetermined etiology group. We prospectively enrolled 308 ischemic stroke patients, whose clinical characteristics and A-S-C-O classifications were compared with analyses of intracranial arteries, carotid arteries, aortic arch, and supra-aortic arteries. 125(40.6%) patients had plaques in the aortic arch or supra-aortic arteries, of which 106 (84.8%) had complex plaques. No correlations were observed between these plaques and carotid plaques ( p = 0.283) or intracranial arterial stenosis ( p = 0.097). After detecting the mobile thrombi in the aortic arch and supra-aortic arteries, the proportion of patients in the atherothrombosis group was increased from 33.8% to 55.5% ( p = 0.00), whereas the proportion of patients in stroke of undetermined etiology group was decreased from 19.2% to 11.0% ( p = 0.00). Examining only the carotid and intracranial arteries may not provide adequate information about large arteries in stroke patients. Therefore, it would be better to include a search for relevant plaques in the aortic arch or supra-aortic arteries in modern stroke workup, for it may lead to more accurate stroke subtype classification and guide secondary prevention.

Mean population systolic blood pressure fell by 2.6 mmHg, resulting in 900 fewer deaths (865 in healthy people, 35 in patients, plus 575 fewer deaths attributable to antihypertensive medication in healthy people. The majority of falls in deaths attributable to risk factors occurred in people without known heart disease: 6,705 fewer deaths compared with 1,985 fewer deaths in patients (secondary prevention, emphasizing the importance of promoting health interventions in the general population.The largest effects on mortality came from primary prevention, giving markedly larger mortality reductions than secondary prevention.

    To investigate effects of surface neuromuscular electrical stimulation applied early after stroke to the wrist and finger extensor muscles on upper limb pain, spasticity and contractures in patients with no functional arm movement. Secondary analysis from a Phase II, randomized, controlled, single-blind study. An acute hospital stroke unit. Patients with no useful arm function within six weeks of a first stroke. Patients were randomized to treatment (30-minute sessions of surface neuromuscular stimulation to wrist and finger extensors and 45 minutes of physiotherapy) or control (45 minutes of physiotherapy) groups. All patients had access to routine care. Treatment was given for six weeks from recruitment. Ninety patients (49% male, median age 74 years (range 32-98), median time since stroke onset three weeks (range one to six weeks)) were included. Treatment compliance was variable (mean 28%). The treatment prevented the development of pain (mean difference in rate of change 0.4 units/week, 95% confidence interval (CI) 0.09 to 0.6). Treatment may have prevented a deterioration in contractures (quantified by measuring passive range of movement) in severely disabled patients (mean rate of deterioration -0.5 deg/week; 95% CI -0.9 to -0.06). There were no significant changes in stiffness and spasticity. Surface neuromuscular electrical stimulation reduces pain in stroke patients with a non-functional arm. There was some evidence that treatment with electrical stimulation was beneficial in reducing contractures. Treatment had no effect on spasticity.

    Perinatal stroke leads to significant morbidity and long-term neurological and cognitive deficits. The pathophysiological mechanisms of brain damage depend on brain maturation at the time of stroke. To understand whether microglial cells limit injury after neonatal stroke by preserving neurovascular integrity, we subjected postnatal day 7 (P7) rats depleted of microglial cells, rats with inhibited microglial TGFbr2/ALK5 signaling, and corresponding controls, to transient middle cerebral artery occlusion (tMCAO). Microglial depletion by intracerebral injection of liposome-encapsulated clodronate at P5 significantly reduced vessel coverage and triggered hemorrhages in injured regions 24 h after tMCAO. Lack of microglia did not alter expression or intracellular redistribution of several tight junction proteins, did not affect degradation of collagen IV induced by the tMCAO, but altered cell types producing TGFβ1 and the phosphorylation and intracellular distribution of SMAD2/3. Selective inhibition of TGFbr2/ALK5 signaling in microglia via intracerebral liposome-encapsulated SB-431542 delivery triggered hemorrhages after tMCAO, demonstrating that TGFβ1/TGFbr2/ALK5 signaling in microglia protects from hemorrhages. Consistent with observations in neonatal rats, depletion of microglia before tMCAO in P9 Cx3cr1(GFP/+)/Ccr2(RFP/+) mice exacerbated injury and induced hemorrhages at 24 h. The effects were independent of infiltration of Ccr2(RFP/+) monocytes into injured regions. Cumulatively, in two species, we show that microglial cells protect neonatal brain from hemorrhage after acute ischemic stroke. Copyright © 2016 the authors 0270-6474/16/362881-13$15.00/0.

    Cryptogenic stroke (or stroke of undetermined cause) is a common cause of stroke and is statistically associated with patent foramen ovale (PFO). The largest study of cryptogenic stroke is the Homma study, which is a sub-study of the WARSS trial; it produced the following data: cryptogenic stroke patients with and without PFO, when treated with either aspirin or warfarin, all had identical recurrence rates. This is puzzling because it seems as though there ought to have been some extra risk in one of the two groups under one of the two treatments. How could everything come out the same? A review of the epidemiology of cryptogenic stroke shows that, compared to patients with stroke of determined cause, cryptogenic stroke patients are a little younger and have lower doses of the usual risk factors (hypertension and diabetes mellitus) but more PFO. Cryptogenic strokes appear to be embolic strokes from an unknown source. A previously published article setting forth a hypothetical theory of stress-induced stroke was used to analyze these data. It is suggested that stress can induce episodic systemic platelet activation and hypercoagulability, which causes transient thrombus formation and subsequent embolization on both the arterial and venous sides of the circulation; the latter requires a PFO to cause a stroke (paradoxical embolism). The sum of these two mechanisms explains cryptogenic stroke. The PFO subset of cryptogenic stroke includes patients with both early and late stage disease who have an aggregate risk approximately equal to that of patients without PFO. Cryptogenic stroke is part of the disease of stress-induced cerebrovascular disease. Aspirin and warfarin have already been shown to be equally effective in secondary prevention of ischemic stroke.

    Sylvester, Jillian E; Belval, Luke N; Casa, Douglas J; O'Connor, Francis G

    Football is recognized as a leading contributor to sports injury secondary to the contact collision nature of the endeavor. While direct deaths from head and spine injury remain a significant contributor to the number of catastrophic injuries, indirect deaths (systemic failure) predominate. Exertional heat stroke has emerged as one of the leading indirect causes of death in high school and collegiate football. This review details for the team physician the unique challenge of exercising in the heat to the football player, and the prevention, diagnosis, management, and return-to-play issues pertinent to exertional heat illnesses.

    Full Text Available Background. Evidences are accumulating that age and gender have great impact on the distribution of stroke risk factors. Such data are lacking in Chinese population. Methods. 1027 patients with first-ever ischemic stroke (IS were recruited and divided into young adult (80 years groups according to stroke onset ages. Vascular risk factors were collected and compared among groups. Results. Female patients were globally older than male patients at stroke onset and having higher prevalence of diabetes mellitus (DM, heart diseases, and atrial fibrillation (AF. However, females were less likely to drink heavily or smoke than males. Young patients had a much higher proportion of smoking and drinking than middle-aged and very old patients and the highest family history of hypertension, while very old patients had the highest prevalence of heart diseases and AF but lowest proportion of positive family history of vascular diseases. Hypertension and DM were equally frequent among three groups. Conclusion. Our study showed that vascular risk factors had a specific age and gender distribution pattern in Chinese IS patients. Secondary prevention strategy should emphasize on the control of different risk factors based on patient’s age and gender.

    Full Text Available Abstract Background Stroke is a serious complication of sickle cell disease (SCD in children. Transcranic Doppler (TCD is a well-established predictor of future cerebrovascular symptoms: a blood flow velocity >200 cm/sec in the Middle Cerebral Artery (MCA correlates with a high risk of stroke in cohorts of African-american HbS/HbS patients. In North-East Italy the recent increase in SCD patients is mainly due to immigration from Africa. A comprehensive care program for children with SCD was established in our Center since 2004, but a wide and routine screening for Primary stroke prevention needs to be developed. Methods In order to verify the feasibility of TCD and Transcranial color coded Sonography (TCCS screening in our setting and the applicability of international reference values of blood velocities to our population of African immigrants with HbS/HbS SCD, we performed TCD and TCCD in 12 HbS/HbS African children and two groups of age-matched controls of Caucasian and African origin respectively. TCD and TCCS were performed on the same day of the scheduled routine hematologic visit after parental education. Results All parents accepted to perform the sonography to their children. TCD and TCCD were performed in all patients and an adequate temporal window could be obtained in all of them. Pulsatility index and depth values in both the MCA and the Basilar Artery (BA were similar at TCD and TCCS evaluation in the three groups while time-average maximum velocities (TAMM, peak systolic velocity and diastolic velocity in the MCA and BA were higher in the patients' group on both TCD and TCCS evaluation. African and Caucasian healthy controls had similar lower values. Conclusion Our preliminary data set the base to further evaluate the implementation of a primary stroke prevention program in our setting of HbS/HbS African immigrants and HbS/beta thalassemia Italians.

    Full Text Available Background : Stroke is one of the most common causes of disabilities and death all over the world. The mortality rate of stroke is predicted to be doubled by 2030 in the Middle East countries. Nutrition is an effective strategy in prevention and management of stroke. This study assessed the relationship between various protein types and stroke risk. Materials and Methods: This hospital-based case-control study was performed in a University hospital. The data regarding consumption of usual food intake of 69 cases (46 men and 23 women and 60 controls (30 men and 30 women was collected with a food frequency questionnaire (FFQ. The mean consumption of red and white meat and vegetable and processed proteins consumption were compared between two groups. Results: The percent of total of daily protein intake were lower in patients with stroke in both sexes (25.92% vs 30.55% in men and 30.7% vs 31.14% in women. Conclusion: Lower protein consumption may be observed in patients with stroke patients in both sex.

    Acute vertigo may be secondary to stroke or to non-ischemic causes. Accurate identification of vertigo secondary to ischemia may lead to appropriate timely intervention that can minimize stroke-related damage and can help in tailoring the most appropriate individual therapy for affected patients. Diffusion weighted MRI (DWI) is very accurate for diagnosing stroke and we therefore aimed to test whether it can aid in making a correct diagnosis of vertigo secondary to stroke. All patients presenting with vertigo in which the diagnosis of stroke was considered underwent DWI only MRI. Data regarding the symptoms and neurological deficits, vascular risk factors, imaging findings, and outcomes was accrued. Patients with stroke on DWI were compared with those without ischemia. Between June 2010 and August 2011, 28 patients fulfilling the entry criteria were identified with a mean age of 62·2±12·8 (60% male). The final diagnosis was stroke in 11 patients (39%). Patients with stroke did not differ from those without stroke in their risk factor profile. However, patients with stroke more often tended to present with vertigo accompanied by other neurological symptoms (73% versus 12% respectively, P = 0·001). After adjusting for age and the presence of diabetes, the presence of multiple symptoms remained the only variable that was associated with a positive DWI scan (odds ratio: 30: 95% confidence interval: 2·6-349). Most patients with stroke had very mild strokes with a median admission NIHSS score of 3 and DWI lesion volumes >2 cm were found in only three patients. Most stroke patients made a good recovery (modified Rankin score ≤2 in seven of nine patients with 90 day data). The most common diagnosis in patients without stroke was of vertigo of peripheral origin (14/17). DWI only MRI can be used to rapidly screen patients presenting with vertigo and suspected vertebrobasilar stroke. The occurrence of vertigo in combination with other focal neurological symptoms may

    In many countries, including Sweden, initiatives have been taken to reduce between-hospital differences in the quality of stroke services. We have explored to what extent hospital type (university, specialized nonuniversity, or community hospital) influences hospital performance. Riksstroke collects clinical data during hospital stay (national coverage 94%). Follow-up data at 3 months were collected using administrative registers and a questionnaire completed by surviving patients (response rate 88%). Structural data were collected from a questionnaire completed by hospital staff (response rate 100%). Multivariate analyses with adjustment for clustering were used to test differences between types of hospitals. The proportion of patients admitted directly to a stroke unit was highest in community hospitals and lowest in university hospitals. Magnetic resonance, carotid imaging, and thrombectomy were more frequently performed in university hospitals, and the door-to-needle time for thrombolysis was shorter. Secondary prevention with antihypertensive drugs was used less often, and outpatient follow-up was less frequent in university hospitals. Fewer patients in community hospitals were dissatisfied with their rehabilitation. After adjusting for possible confounders, poor outcome (dead or activities of daily living dependency 3 months after stroke) was not significantly different between the 3 types of hospital. In a setting with national stroke guidelines, stroke units in all hospitals, and measurement of hospital performance and benchmarking, outcome (after case-mix adjustment) is similar in university, specialized nonuniversity, and community hospitals. There seems to be fewer barriers to organizing well-functioning stroke services in community hospitals compared with university hospitals. © 2015 American Heart Association, Inc.

    Detecting paroxysmal atrial fibrillation (AF) in patients with ischemic strokes presenting in sinus rhythm is challenging because episodes are often short, occur randomly, and are frequently asymptomatic. If AF is detected, recurrent thromboembolism can be prevented efficiently by oral anticoagulation. Numerous uncontrolled studies using various electrocardiogram (ECG) devices have established that prolonged ECG monitoring increases the yield of AF detection, but most established procedures are time-consuming and costly. The few randomized trials are mostly limited to cryptogenic strokes. The optimal method, duration, and patient selection remain unclear. Repeated prolonged continuous Holter ECG monitoring to detect paroxysmal AF within an unspecific stroke population may prove to be a widely applicable, effective secondary prevention strategy. Find-AFRANDOMISED is a randomized and controlled prospective multicenter trial. Four hundred patients 60 years or older with manifest (symptoms ≥24 hours or acute computed tomography/magnetic resonance imaging lesion) and acute (symptoms ≤7 days) ischemic strokes will be included at 4 certified stroke centers in Germany. Those with previously diagnosed AF/flutter, indications/contraindications for oral anticoagulation, or obvious causative blood vessel pathologies will be excluded. Patients will be randomized 1:1 to either enhanced and prolonged Holter ECG monitoring (10 days at baseline and after 3 and 6 months) or standard of care (≥24-hour continuous ECG monitoring, according to current stroke guidelines). All patients will be followed up for at least 12 months. The primary end point is newly detected AF (≥30 seconds) after 6 months, confirmed by an independent adjudication committee. We plan to complete recruitment in autumn 2014. First results can be expected by spring 2016. Copyright © 2014 Mosby, Inc. All rights reserved.

    Stroke symptoms are common among people without a history of stroke or transient ischemic attack. Reported stroke symptoms may represent stroke episodes that failed to reach the threshold for clinical diagnosis. This study aimed to assess in the Lebanese population the prevalence of self-reported stroke symptoms in a stroke- and transient ischemic attack-free population, and the association of these symptoms with major risk factors for stroke. We carried out a cross-sectional study using a multistage cluster sample across Lebanon. We interviewed residents aged 40 years and more. Stroke symptoms were assessed using the Questionnaire for Verifying Stroke-Free Status. We included 1515 individuals (mean age was 57·2 ± 12·4 years, 783 women, 51·7%). Among 1460 participants stroke- and transient ischemic attack-free, 175 had experienced at least one stroke symptom (12·1%, 95% CI 9·9%-14·3%). Arterial hypertension (adjOR 4·37, 95% CI 2·68-7·12), history of heart disease (adjOR 3·34, 95% CI 2·00-5·56), current waterpipe smoking (adjOR 3·88, 95% CI 2·33-6·48), current and former cigarette smoking (adjOR 1·84, 95% CI 1·18-2·87 and adjOR 2·01, 95% CI 1·13-3·5, respectively), psychological distress (adjOR 1·04, 95% CI 1·02-1·05), the Mediterranean diet score (adjOR 0·87, 95% CI 0·76-0·99), and regular physical activity (adjOR 0·45, 95% CI 0·26-0·77) were independently associated with stroke symptoms. This is the first study conducted in the Middle East, assessing self-reported stroke symptoms among stroke-free residents. Our study showed that almost one in eight residents without a history of stroke or transient ischemic attack has had stroke symptoms. Major vascular risk factors are associated with these symptoms, thus allowing for prevention strategies. © 2015 World Stroke Organization.

    Full Text Available OBJECTIVE: To compare frontal sinus cranialization to obliteration for future prevention of secondary mucocele formation following open surgery for benign lesions of the frontal sinus. STUDY DESIGN: Retrospective case series. SETTING: Tertiary academic medical center. PATIENTS: Sixty-nine patients operated for benign frontal sinus pathology between 1994 and 2011. INTERVENTIONS: Open excision of benign frontal sinus pathology followed by either frontal obliteration (n = 41, 59% or frontal cranialization (n = 28, 41%. MAIN OUTCOME MEASURES: The prevalence of post-surgical complications and secondary mucocele formation were compiled. RESULTS: Pathologies included osteoma (n = 34, 49%, mucocele (n = 27, 39%, fibrous dysplasia (n = 6, 9%, and encephalocele (n = 2, 3%. Complications included skin infections (n = 6, postoperative cutaneous fistula (n = 1, telecanthus (n = 4, diplopia (n = 3, nasal deformity (n = 2 and epiphora (n = 1. None of the patients suffered from postoperative CSF leak, meningitis or pneumocephalus. Six patients, all of whom had previously undergone frontal sinus obliteration, required revision surgery due to secondary mucocele formation. Statistical analysis using non-inferiority test reveal that cranialization of the frontal sinus is non-inferior to obliteration for preventing secondary mucocele formation (P<0.0001. CONCLUSION: Cranialization of the frontal sinus appears to be a good option for prevention of secondary mucocele development after open excision of benign frontal sinus lesions.

    The risk of recurrent stroke is up to 10% in the week after a transient ischaemic attack (TIA) or minor stroke. Modelling studies suggest that urgent use of existing preventive treatments could reduce the risk by 80-90%, but in the absence of evidence many health-care systems make little provision. Our aim was to determine the effect of more rapid treatment after TIA and minor stroke in patients who are not admitted direct to hospital. We did a prospective before (phase 1: April 1, 2002, to Sept 30, 2004) versus after (phase 2: Oct 1, 2004, to March 31, 2007) study of the effect on process of care and outcome of more urgent assessment and immediate treatment in clinic, rather than subsequent initiation in primary care, in all patients with TIA or minor stroke not admitted direct to hospital. The study was nested within a rigorous population-based incidence study of all TIA and stroke (Oxford Vascular Study; OXVASC), such that case ascertainment, investigation, and follow-up were complete and identical in both periods. The primary outcome was the risk of stroke within 90 days of first seeking medical attention, with independent blinded (to study period) audit of all events. Of the 1278 patients in OXVASC who presented with TIA or stroke (634 in phase 1 and 644 in phase 2), 607 were referred or presented direct to hospital, 620 were referred for outpatient assessment, and 51 were not referred to secondary care. 95% (n=591) of all outpatient referrals were to the study clinic. Baseline characteristics and delays in seeking medical attention were similar in both periods, but median delay to assessment in the study clinic fell from 3 (IQR 2-5) days in phase 1 to less than 1 (0-3) day in phase 2 (prisk of recurrent stroke in the patients referred to the study clinic was 10.3% (32/310 patients) in phase 1 and 2.1% (6/281 patients) in phase 2 (adjusted hazard ratio 0.20, 95% CI 0.08-0.49; p=0.0001); there was no significant change in risk in patients treated elsewhere.

    Swipe out Stroke (SOS) examines the use of a smartphone-based mobile application to reduce obesity in high-risk minority stroke patients. At record-high levels in the United States, obesity disproportionately affects minorities and is highly correlated with cerebrovascular disease. Unfortunately, structured weight loss programs are expensive, and compliance significantly decreases upon program completion. Mobile health (mHealth) technology is an innovative, cost-effective way to bridge this gap. Minorities spend over 4.5 billion dollars annually on consumer electronics, making studies that utilize mHealth applications ideal for health promotion and disease prevention. SOS is a prospective, randomized-controlled trial with open blinded endpoint comparing an mHealth based dietary intervention to usual care to facilitate weight reduction. Ischemic and hemorrhagic stroke survivors and their carers are recruited from the acute care service of a Houston-based comprehensive stroke center. A neurorehabilitation physician or vascular neurologist meets with participants during the index hospitalization, a baseline clinic visit, followed by visits at 1, 3, and 6 month intervals. The SOS Team focuses on feasible modifications to the Southern dietary pattern (fried foods, fatty foods, added fats, eggs, processed meats, such as bacon and ham, organ meats (e.g., liver), and sweetened drinks) and caloric restriction to facilitate a 5% reduction in total body weight. Practical barriers to adherence are addressed, such as access to transportation, financial limitations, and depression. The primary dependent measure is a reduction of total body weight. Secondary outcomes include systolic blood pressure, hemoglobin A1c, low-density lipoprotein, triglycerides, and Factor VIII. SOS will determine whether a Phase III effectiveness trial of a smartphone-based mobile application to address obesity-related health disparities is warranted throughout the Southeastern United States (Stroke

    Cardioembolic (CE) strokes are more disabling and more fatal than non-CE strokes. Multiple prognostic factors have been recognized, but the magnitude of their relative contributions has not been well explored. Using a prospective stroke outcome database, we compared the 3-month outcomes of CE and non-CE strokes. We assessed the relative contribution of each prognostic factor of initial stroke severity, poststroke complications, and baseline characteristics with multivariable analyses and model fitness improvement using -2 log-likelihood and Nagelkerke R2. This study included 1233 patients with acute ischemic stroke: 193 CE strokes and 1040 non-CE strokes. Compared with the non-CE group, CE group had less modified Rankin Scale (mRS) 0-2 outcomes (47.2% versus 68.5%; odds ratio [95% confidence interval], .41 [.30-.56]), less mRS 0-1 outcomes (33.7% versus 53.5%; .44 [.32-.61]), more mRS 5-6 outcomes (32.1% versus 10.9%; 3.88 [2.71-5.56]), and higher mortality (19.2% versus 5.2%; 4.33 [2.76-6.80]) at 3 months. When adjusting either baseline characteristics or poststroke complications, the outcome differences between the 2 groups remained significant. However, adjusting initial National Institute of Health Stroke Scale (NIHSS) score alone abolished all outcome differences except for mortality. For mRS 0-2 outcomes, the decrement of -2 log-likelihood and the Nagelkerke R2 of the model adjusting initial NIHSS score alone approached 70.2% and 76.7% of the fully adjusting model. Greater stroke severity predominates over all other factors for the worse outcome of CE stroke. Primary prevention and more efficient acute therapy for stroke victims should be given top priorities to reduce the burden of CE strokes. Copyright © 2013 National Stroke Association.

    2015-04-01

    Full Text Available Clostridium difficile infections are a global clinical concern and are one of the leading causes of nosocomial outbreaks. Preventing these infections has benefited from multidisciplinary infection control strategies and new antibiotics, but the problem persists. Probiotics are effective in preventing antibiotic-associated diarrhea and may also be a beneficial strategy for C. difficile infections, but randomized controlled trials are scarce. This meta-analysis pools 21 randomized, controlled trials for primary prevention of C. difficile infections (CDI and four trials for secondary prevention of C. difficile recurrences and assesses the efficacy of specific probiotic strains. Four probiotics significantly improved primary CDI prevention: (Saccharomyces boulardii, Lactobacillus casei DN114001, a mixture of L. acidophilus and Bifidobacterium bifidum, and a mixture of L. acidophilus, L. casei and L. rhamnosus. None of the tested probiotics significantly improved secondary prevention of CDI. More confirmatory randomized trials are needed to establish if probiotics are useful for preventing C. difficile infections. v

    Full Text Available Perindopril/indapamide combination has been shown to reduce cardiovascular risk in different groups of patients. A total of 18,529 patients (9,272 receiving perindopril/indapamide and 9,257 receiving placebo were included in this meta-analysis involving three large randomized clinical trials-ADVANCE, PROGRESS and HYVET. A non-significant reduction in fatal and non-fatal stroke was seen (Odds ratio 0.73; 95% Confidence Interval 0.49 to 1.09; z=1.52 and p= 0.13. The combination was associated with a significantly reduction of vascular death (Odds ratio 0.79; 95% Confidence Interval 0.69 to 0.90; z=3.48 and p=0.0005 and major cardio-vascular events (Odds ratio 0.72; 95% Confidence Interval 0.53 to 0.97; z=2.15 and p= 0.03. Fixed-combination of Perindopril and indapamide substantially reduced major cardiovascular event and vascular death. However, effect on stroke needs further evaluation.

    Full Text Available Abstract: Patients who have recovered from a prior stroke may experience a reemergence of their original stroke syndrome secondary to metabolic derangements, sedation, infection, and/or fatigue. Critically, the molecular/cellular mechanisms mediating symptom recurrence after exposure to analgesic agents remain unknown. Accordingly, herein we report a unique case of a patient with hydromorphone-induced recrudescence 30 years after her initial stroke event(s, and in so doing propose a putative mechanism related to post-infarction functional neuroplasticity.

    2003-08-01

    Full Text Available Abstract Background Atrial fibrillation (AF is an important independent risk factor for stroke. Randomised controlled trials have shown that this risk can be reduced substantially by treatment with warfarin or more modestly by treatment with aspirin. Existing trial data for the effectiveness of warfarin are drawn largely from studies in selected secondary care populations that under-represent the elderly. The Birmingham Atrial Fibrillation Treatment of the Aged (BAFTA study will provide evidence of the risks and benefits of warfarin versus aspirin for the prevention of stroke for older people with AF in a primary care setting. Study design A randomised controlled trial where older patients with AF are randomised to receive adjusted dose warfarin or aspirin. Patients will be followed up at three months post-randomisation, then at six monthly intervals there after for an average of three years by their general practitioner. Patients will also receive an annual health questionnaire. 1240 patients will be recruited from over 200 practices in England. Patients must be aged 75 years or over and have AF. Patients will be excluded if they have a history of any of the following conditions: rheumatic heart disease; major non-traumatic haemorrhage; intra-cranial haemorrhage; oesophageal varices; active endoscopically proven peptic ulcer disease; allergic hypersensitivity to warfarin or aspirin; or terminal illness. Patients will also be excluded if the GP considers that there are clinical reasons to treat a patient with warfarin in preference to aspirin (or vice versa. The primary end-point is fatal or non-fatal disabling stroke (ischaemic or haemorrhagic or significant arterial embolism. Secondary outcomes include major extra-cranial haemorrhage, death (all cause, vascular, hospital admissions (all cause, vascular, cognition, quality of life, disability and compliance with study medication.

    This study evaluates the effects of a 3-year smoking prevention programme in secondary schools in Helsinki. The study is part of the European Smoking prevention Framework Approach (ESFA), in which Denmark, Finland, the Netherlands, Portugal, Spain and the UK participated. A total of 27 secondary schools in Finland participated in the programme (n = 1821). Schools were randomised into experimental (13) and control groups (14). The programme included 14 information lessons about smoking and refusal skills training. The 3-year smoking prevention programme was also integrated into the standard curriculum. The community-element of the programme included parents, parish confirmation camps and dentists. The schools in the experimental group received the prevention programme and the schools in the control group received the standard health education curriculum. Among baseline never smokers (60.8%), the programme had a significant effect on the onset of weekly smoking in the experimental group [OR = 0.63 (0.45-0.90) P = 0.009] when compared with the control group. Being female, doing poorly at school, having parents and best friends who smoke and more pocket money to spend compared with others were associated with an increased likelihood of daily and weekly smoking onset. These predictors did not have an interaction effect with the experimental condition. This study shows that a school- and community-based smoking prevention programme can prevent smoking onset among adolescents.

    Context: Poststroke care in developing countries is inundated with poor concordance and scarce specialist stroke care providers. A primary care-driven health service is an option to ensure optimal care to poststroke patients residing at home in the community. Aims: We assessed outcomes of a pilot long-term stroke care clinic which combined secondary prevention and rehabilitation at community level. Settings and Design: A prospective observational study of stroke patients treated between 2008 and 2010 at a primary care teaching facility. Subjects and Methods: Analysis of patients was done at initial contact and at 1-year post treatment. Clinical outcomes included stroke risk factor(s) control, depression according to Patient Health Questionnaire (PHQ9), and level of independence using Barthel Index (BI). Statistical Analysis Used: Differences in means between baseline and post treatment were compared using paired t-tests or Wilcoxon-signed rank test. Significance level was set at 0.05. Results: Ninety-one patients were analyzed. Their mean age was 62.9 [standard deviation (SD) 10.9] years, mean stroke episodes were 1.30 (SD 0.5). The median interval between acute stroke and first contact with the clinic 4.0 (interquartile range 9.0) months. Mean systolic blood pressure decreased by 9.7 mmHg (t = 2.79, P = 0.007), while mean diastolic blood pressure remained unchanged at 80mmHg (z = 1.87, P = 0.06). Neurorehabilitation treatment was given to 84.6% of the patients. Median BI increased from 81 (range: 2−100) to 90.5 (range: 27−100) (Z = 2.34, P = 0.01). Median PHQ9 scores decreased from 4.0 (range: 0−22) to 3.0 (range: 0−19) though the change was not significant (Z= −0.744, P = 0.457). Conclusions: Primary care-driven long-term stroke care services yield favorable outcomes for blood pressure control and functional level. PMID:24347948

    Background After a transient ischemic attack (TIA) or minor stroke, the long-term risk of stroke and other vascular events is not well known. In this follow-up to a report on 1-year outcomes from a registry of TIA clinics in 21 countries that enrolled 4789 patients with a TIA or minor ischemic stroke from 2009 through 2011, we examined the 5-year risk of stroke and vascular events. Methods We evaluated patients who had had a TIA or minor stroke within 7 days before enrollment in the registry. Among 61 sites that participated in the 1-year outcome study, we selected 42 sites that had follow-up data on more than 50% of their enrolled patients at 5 years. The primary outcome was a composite of stroke, acute coronary syndrome, or death from cardiovascular causes (whichever occurred first), with an emphasis on events that occurred in the second through fifth years. In calculating the cumulative incidence of the primary outcome and secondary outcomes (except death from any cause), we treated death as a competing risk. Results A total of 3847 patients were included in the 5-year follow-up study; the median percentage of patients with 5-year follow-up data per center was 92.3% (interquartile range, 83.4 to 97.8). The composite primary outcome occurred in 469 patients (estimated cumulative rate, 12.9%; 95% confidence interval [CI], 11.8 to 14.1), with 235 events (50.1%) occurring in the second through fifth years. At 5 years, strokes had occurred in 345 patients (estimated cumulative rate, 9.5%; 95% CI, 8.5 to 10.5), with 149 of these patients (43.2%) having had a stroke during the second through fifth years. Rates of death from any cause, death from cardiovascular causes, intracranial hemorrhage, and major bleeding were 10.6%, 2.7%, 1.1%, and 1.5%, respectively, at 5 years. In multivariable analyses, ipsilateral large-artery atherosclerosis, cardioembolism, and a baseline ABCD 2 score for the risk of stroke (range, 0 to 7, with higher scores indicating greater risk) of 4

    Several Western and Arab countries, as well as over 30 States in the US are using the "All-Patient Refined Diagnosis-Related Groups" (APR-DRGs) with four severity-of-illness (SOI) subcategories as a model for hospital funding. The aim of this study is to verify whether this is an adequate model for funding stroke hospital admissions, and to explore which risk factors and complications may influence the amount of funding. A bottom-up analysis of 2496 ischaemic stroke admissions in Belgium compares detailed in-hospital resource use (including length of stay, imaging, lab tests, visits and drugs) per SOI category and calculates total hospitalisation costs. A second analysis examines the relationship between the type and location of the index stroke, medical risk factors, patient characteristics, comorbidities and in-hospital complications on the one hand, and the funding level received by the hospital on the other hand. This dataset included 2513 hospitalisations reporting on 35,195 secondary diagnosis codes, all medically coded with the International Classification of Disease (ICD-9). Total costs per admission increased by SOI (€3710-€16,735), with severe patients costing proportionally more in bed days (86%), and milder patients costing more in medical imaging (24%). In all resource categories (bed days, medications, visits and imaging and laboratory tests), the absolute utilisation rate was higher among severe patients, but also showed more variability. SOI 1-2 was associated with vague, non-specific stroke-related ICD-9 codes as primary diagnosis (71-81% of hospitalisations). 24% hospitalisations had, in addition to the primary diagnosis, other stroke-related codes as secondary diagnoses. Presence of lung infections, intracranial bleeding, severe kidney disease, and do-not-resuscitate status were each associated with extreme SOI (p DRG with SOI subclassification is a useful funding model as it clusters stroke patients in homogenous groups in terms of

    Full Text Available The aim of this study was to assess the level of availability of HIV prevention strategies in secondary schools in Kabarole district, Uganda in order to inform the design of interventions to strengthen HIV Prevention and psychosocial support. Quantitative and qualitative research methods were used in eight secondary schools in Kabarole district to establish available HIV prevention and psychosocial support services. Questionnaires were administered to 355 students 12-24 years old. In addition, 20 Key Informant interviews were held with education service providers. Quantitative data was analyzed using Epi-data and qualitative data were analyzed by thematic content analysis. Seven of the eight schools had at least one HIV prevention strategy. Two teachers in each of the five schools had been trained in HIV prevention. No school had a nurse trained in HIV prevention, care and support. Education service providers had limited knowledge of HIV prevention support and care of students living with HIV. We found out that students had knowledge on how one can acquire HIV. HIV prevention services reported by students in schools included: talks from teachers and guests (19%, drama with HIV prevention related messages (16%, peer education clubs (15%, workshops and seminars on HIV (8%, sensitization about HIV/AIDS (7%, guidance and counseling (6%, talking compounds- (5%, abstinence talks (6%, keeping students busy in sports (4%, straight talk (4%. Sixty three percent reported receiving HIV reading materials from various sources. Preventing HIV infection among students in schools is still demanding with limited interventions for students. Efforts to support school interventions should focus on including HIV Prevention in the school curriculum, working with peer educators as well as education service providers who spend much of the time with the students while at school.

    Advances in stroke care will have the greatest effect on stroke outcome if care is delivered within a regional stroke system designed to improve both efficiency and effectiveness. The ultimate goal of stroke care is to minimize ongoing injury, emergently recanalize acute vascular occlusions, and begin secondary measures to maximize functional recovery. These efforts will provide stroke patients with the greatest opportunity for a return to previous quality of life and decrease the overall societal burden of stroke.

    Full Text Available BACKGROUND: Epidemiologic studies suggest that LDL particle concentration (LDL-P may remain elevated at guideline recommended LDL cholesterol goals, representing a source of residual risk. We examined the following seven separate lipid parameters in achieving the LDL-P goal of <1000 nmol/L goal for very high risk secondary prevention: total cholesterol to HDL cholesterol ratio, TC/HDL, <3; a composite of ATP-III very high risk targets, LDL-C<70 mg/dL, non-HDL-C<100 mg/dL and TG<150 mg/dL; a composite of standard secondary risk targets, LDL-C<100, non-HDL-C<130, TG<150; LDL phenotype; HDL-C ≥ 40; TG<150; and TG/HDL-C<3. METHODS: We measured ApoB, ApoAI, ultracentrifugation lipoprotein cholesterol and NMR lipoprotein particle concentration in 148 unselected primary and secondary prevention patients. RESULTS: TC/HDL-C<3 effectively discriminated subjects by LDL-P goal (F = 84.1, p<10(-6. The ATP-III very high risk composite target (LDL-C<70, nonHDL-C<100, TG<150 was also effective (F = 42.8, p<10(-5. However, the standard secondary prevention composite (LDL-C<100, non-HDL-C<130, TG<150 was also effective but yielded higher LDL-P than the very high risk composite (F = 42.0, p<10(-5 with upper 95% confidence interval of LDL-P less than 1000 nmol/L. TG<150 and TG/HDL-C<3 cutpoints both significantly discriminated subjects but the LDL-P upper 95% confidence intervals fell above goal of 1000 nmol/L (F = 15.8, p = 0.0001 and F = 9.7, p = 0.002 respectively. LDL density phenotype neared significance (F = 2.85, p = 0.094 and the HDL-C cutpoint of 40 mg/dL did not discriminate (F = 0.53, p = 0.47 alone or add discriminatory power to ATP-III targets. CONCLUSIONS: A simple composite of ATP-III very high risk lipoprotein cholesterol based treatment targets or TC/HDL-C ratio <3 most effectively identified subjects meeting the secondary prevention target level of LDL-P<1000 nmol/L, providing a potential alternative to advanced lipid testing in many clinical

    Mobile health, or mHealth, has increasingly been signaled as an effective means to expedite communication and improve medical regimen adherence, especially for patients with chronic health conditions such as stroke. However, there is a lack of data on attitudes of stroke patients toward mHealth. Such information will aid in identifying key indicators for feasibility and optimal implementation of mHealth to prevent and/or decrease rates of secondary stroke. Our objective was to ascertain stroke patients' attitudes toward using mobile phone enabled blood pressure (BP) monitoring and medication adherence and identify factors that modulate these attitudes. Sixty stroke patients received a brief demonstration of mHealth devices to assist with BP control and medication adherence and a survey to evaluate willingness to use this technology. The 60 participants had a mean age of 57 years, were 43.3% male, and 53.3% were White. With respect to telecommunication prevalence, 93.3% owned a cellular device and 25% owned a smartphone. About 70% owned a working computer. Regarding attitudes, 85% felt comfortable with a doctor or nurse using mHealth technologies to monitor personal health information, 78.3% believed mHealth would help remind them to follow doctor's directions, and 83.3% were confident that technology could effectively be used to communicate with health care providers for medical needs. Mobile device use is high in stroke patients and they are amenable to mHealth for communication and assistance in adhering to their medical regimens. More research is needed to explore usefulness of this technology in larger stroke populations.

    Intracranial stenosis accounts for 8-10% of all ischemic strokes in North America, a frequency slightly less than that of extracranial carotid stenosis. Among patients presenting with transient ischemic attack or stroke due to intracranial stenosis, the risk of recurrent stroke in the first year after initial symptoms is about 14%. Those with high-risk features (recent stroke and severe stenosis) have up to a 23% rate of recurrent stroke in the year after their initial event. Angioplasty with stenting has emerged as a potential treatment strategy, particularly in high-risk patients, although evidence is currently limited to uncontrolled prospective trials and retrospective case series. In this article, we critically review the clinical results supporting the use of stenting and highlight some key considerations in the application of this technology, including patient selection, procedural management, technical issues, and risk factors for complications and in-stent restenosis.

  7. Contemporary approach to stroke prevention in atrial fibrillation: Risks, benefits, and new options.

    Science.gov (United States)

    Stock, Jonathan; Malm, Brian J

    2018-04-04

    Atrial fibrillation is a common diagnosis affecting nearly 3 million adults in the United States. Morbidity and mortality in these patients is driven largely by the associated increased risk of thromboembolic complications, especially stroke. Atrial fibrillation is a stronger risk factor than hypertension, coronary disease, or heart failure and is associated with an approximately five-fold increased risk. Mitigating stroke risk can be challenging and requires accurate assessment of stroke risk factors and careful selection of appropriate therapy. Anticoagulation, including the more recently introduced direct oral anticoagulants, is the standard of care for most patients. In addition, emerging non-pharmacologic mechanical interventions are playing an expanding role in reducing stroke risk in select patients. In this review we highlight the current approach to stroke risk stratification in atrial fibrillation and discuss in detail the mechanism, risks, and benefits of current and evolving therapies.

    There is a relative lack of longitudinal studies investigating stroke-specific outcomes and quality of life (QOL). This study aimed to identify which factors (level of disability, cognitive functioning, depressive symptoms, physical activity, and work and social engagement) were independently associated with each stroke-specific domain of QOL, adjusting for age and gender, at 3 months and 12 months post-stroke in an Australian cohort. Survivors of ischemic stroke were recruited from 18 sites of the STroke imAging pRevention and Treatment (START) longitudinal cohort study. Survivors were assessed at 3 months (n = 185) and 12 months (n = 170) post-stroke using the Stroke Impact Scale (SIS), modified Rankin Scale (mRS), Montreal Cognitive Assessment (MoCA), Montgomery-Asberg Depression Rating Scale, Rapid Assessment of Physical Activity, and Work and Social Adjustment Scale (WSAS). WSAS was independently associated with the SIS domains of: Physical Composite function; Participation; and Perceived Recovery at 3 months and 12 months and SIS domain of Emotion at 12 months post-stroke. The presence of depressive symptoms was independently associated with the SIS domains of: Memory and Thinking; and Emotion at 3 months. At 12 months post-stroke, mRS was independently associated with SIS domain of Physical Composite function and MoCA with SIS domain of Communication. Engaging in work and social activities is an important factor associated with stroke-specific domains of QOL over time. It is recommended that services focus on improving work and social engagement given their importance related to QOL in the first year of recovery post-stroke. Identifying and treating those with depressive symptoms may enhance QOL in the early months post-stroke.

    2018-01-01

    To determine the influence of time since injury on the efficacy and maintenance of gains of rehabilitation of balance after stroke. Forty-seven participants were assigned to a least (6-12 months), a moderate (12-24 months), or a most chronic (>24 months) group. Participants trained for 20 one-hour sessions, administered three to five times a week, combining conventional physical therapy and visual feedback-based exercises that trained the ankle and hip strategies. Participants were assessed before, after the intervention, and one month later with a posturography test (Sway Speed and Limits of Stability) and clinical scales. In contrast to other subjects, the most chronic participants failed to improve their sway and to maintain the benefits detected in the Limits of Stability after the intervention. Although all the participants improved in those clinical tests that better matched the trained skills, time since injury limited the improvement, and over all, the maintenance of gains. Time since injury limits but does not prevent improvement in chronic stages post-stroke, and this effect appears to be more pronounced with maintaining gains. These findings support that training duration and intensity as well as type of therapy may need to be adjusted based on time post-stroke.

    BACKGROUND AND PURPOSE: Psychosocial stress at work has been proposed to be a risk factor for cardiovascular disease. However, its role as a risk factor for stroke is uncertain. METHODS: We conducted an individual-participant-data meta-analysis of 196 380 males and females from 14 European cohort...... studies to investigate the association between job strain, a measure of work-related stress, and incident stroke. RESULTS: In 1.8 million person-years at risk (mean follow-up 9.2 years), 2023 first-time stroke events were recorded. The age- and sex-adjusted hazard ratio for job strain relative to no job....... CONCLUSION: Job strain may be associated with an increased risk of ischemic stroke, but further research is needed to determine whether interventions targeting job strain would reduce stroke risk beyond existing preventive strategies....

    To examine the efficiency of electrical stimulation in combination with Bobath techniques in the prevention of inferior and anterior shoulder subluxation in acute stroke patients. A prospective randomized controlled trial. Intensive care unit and inpatient clinics of neurology in a university hospital. Forty-eight patients with acute stroke, divided equally into control and study groups. Subjects in both groups were treated in accordance with the Bobath concept during the early hospitalization period. In addition to Bobath techniques, electrical stimulation was also applied to the supraspinatus muscle, mid and posterior portions of the deltoid muscle of patients in the study group. Two radiological methods were used to measure the horizontal, vertical and total asymmetry and vertical distance values of the shoulder joint. Motor functions of the arm were evaluated with the Motor Assessment Scale. The hospitalization period was 12.62 ± 2.24 days for the control group and 11.66 ± 1.88 days for the study group. Shoulder subluxation occurred in 9 (37.5%) subjects in the control group, whereas it was not observed in the study group. All shoulder joint displacement values were higher in the control group than in the study group (horizontal asymmetry P = 0.0001, vertical asymmetry P = 0.0001, total asymmetry P = 0.0001, vertical range P = 0.002). Application of electrical stimulation combined with the Bobath approach proved to be efficient in preventing inferior and anterior shoulder subluxation in the acute stages of stroke.

    Full Text Available Ischemic stroke is a common neurological disorder and the burden in the world is growing. This study aims to explore the effect of sex and age difference on ischemic stroke using integrated microarray datasets. The results showed a dramatic difference in whole gene expression profiles and influenced pathways between males and females, and also in the old and young individuals. Furthermore, compared with old males, old female patients showed more serious biological function damage. However, females showed less affected pathways than males in young subjects. Functional interaction networks showed these differential expression genes were mostly related to immune and inflammation-related functions. In addition, we found ARG1 and MMP9 were up-regulated in total and all subgroups. Importantly, IL1A, ILAB, IL6 and TNF and other anti-stroke target genes were up-regulated in males. However, these anti-stroke target genes showed low expression in females. This study found huge sex and age differences in ischemic stroke especially the opposite expression of anti-stroke target genes. Future studies are needed to uncover these pathological mechanisms, and to take appropriate pre-prevention, treatment and rehabilitation measures.

In limited reports, most ischemic strokes following trauma were detected after a considerable delay. Early recognition of stroke following trauma might reduce secondary neurologic complications. We report a case of posterior cerebral artery area infarct following multiple traumas in a child. A comprehensive etiologic survey was undertaken and discussed. Although the definite pathogenesis is still unclear, adequate, individualized, and uncomplicated management can significantly affect the outcome.

    The aim of this paper is to underline the importance of the role of general practitioners (GPs) in distributing vital information about prevention to citizens, to highlight the importance of the so-called voluntary prevention programmes, both for conditions for which no organised screening programmes exist and for those for which they do exist but may well be obsolete or inefficient. Nowadays, voluntary prevention is made more effective thanks to the new sophisticated diagnostic technologies applied worldwide by diagnostic imaging. Epidemiological data about the incidence and causes of death among the Italian population have shown that screening programmes should be aimed first at fighting the following diseases: prostatic carcinoma, lung cancer, colorectal carcinoma, breast cancer, cardiovascular disease, cerebrovascular disease, aortic and peripheral vascular disease. GPs do not generally give good or adequate instructions concerning voluntary prevention programmes; GPs may not even be aware of this type of prevention which could represent a valuable option together with the existing mass screening programmes. Therefore, in the following analysis, we aim to outline the correct diagnostic pathway for the prevention of diseases having the highest incidence in our country and which represent the most frequent causes of death. If used correctly, these screening programmes may contribute to the success of secondary prevention, limiting the use of tertiary prevention and thus producing savings for the Italian National Health System.

    Elevated concentrations of homocysteine are associated with cerebral small vessel disease (CSVD). B-vitamin supplementation with folate and vitamins B12 and B6 reduces homocysteine concentrations. In a substudy of the VITAmins TO Prevent Stroke (VITATOPS) trial, we assessed the hypothesis that the addition of once-daily supplements of B vitamins would reduce the progression of CSVD-related brain lesions. A total of 359 patients with recent stroke or transient ischemic attack, who were randomly allocated to double-blind treatment with placebo or b vitamins, underwent brain MRI at randomization and after 2 years of B-vitamin supplementation. MR images were analyzed blinded to treatment allocation. Outcomes related to the prespecified hypothesis were progression of white matter hyperintensities and incident lacunes. We also explored the effect of B-vitamin supplementation on the incidence of other ischemic abnormalities. After 2 years of treatment with b vitamins or placebo, there was no significant difference in white matter hyperintensities volume change (0.08 vs 0.13 cm3; P=0.419) and incidence of lacunes (8.0% vs 5.9%, P=0.434; odds ratio=1.38). In a subanalysis of patients with MRI evidence of severe CSVD at baseline, b-vitamin supplementation was associated with a significant reduction in white matter hyperintensities volume change (0.3 vs 1.7 cm3; P=0.039). Daily B-vitamin supplementation for 2 years did not significantly reduce the progression of brain lesions resulting from presumed CSVD in all patients with recent stroke or transient ischemic attack but may do so in the subgroup of patients with recent stroke or transient ischemic attack and severe CSVD. http://vitatops.highway1.com.au/.

    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.

  19. What is the evidence for using family based interventions to prevent stroke recurrence?

    Stroke has a devastating impact on individuals and families. Risk factors for recurrence include lifestyle behaviours such as smoking, excessive alcohol consumption, an unhealthy diet and physical inactivity. This article describes a programme of research that aims to gather and synthesise the evidence required to inform the development and evaluation of a family centred, behavioural intervention designed to address lifestyle risk factors for recurrent stroke. We present an overview of the research undertaken to develop the evidence base. This included a survey of stroke nurse practice, a focus group study with people who had had a stroke as well as their family members, and a systematic review of the efficacy of lifestyle interventions.

    on the International Classification of Diseases and the pathology behind each code by checking multiple causes of death and literature review. RESULTS: Unspecified stroke and primary and secondary hypertension are leading contributing 'GCs' to stroke mortality estimates for hemorrhagic stroke (HS) and ischemic stroke...... (IS). There were marked differences in the fraction of death assigned to IS and HS for unspecified stroke and hypertension between GBD regions and between age groups. CONCLUSIONS: A large proportion of stroke fatalities are derived from the redistribution of 'unspecified stroke' and 'hypertension...
