    adjustment for potential confounders: sex, age, smoking, inhalation, body mass index, systolic blood pressure, triglycerides, physical activity in leisure time, education, diabetes mellitus, and antihypertensive treatment. RESULTS: We found an inverse association between FEV1 and risk of first-time stroke....... For each 10% decrease in FEV1 in percentage of expected, the relative risk (RR) increased 1.05 (95% CI : 1.00-1.09, P = 0.03). This represents an approximately 30% higher risk of stroke in the group of people with the lowest lung function as compared to the group with the highest lung function...... function groups. CONCLUSIONS: This study shows that reduced lung function measured in percentage of predicted FEV1 is a predictor of first-time stroke and fatal stroke independent of smoking and inhalation. The high risk of fatal first-ever stroke in the group of people with low lung function may...

    Full Text Available Abstract Background The influence of temperature on acute myocardial infarction (AMI has not been investigated as extensively as the effects of broader outcomes of morbidity and mortality. Sixteen studies reported inconsistent results and two considered confounding by air pollution. We addressed some of the methodological limitations of the previous studies in this study. Methods This is the first study of the association between the daily 3-hour maximum apparent temperature (Tappmax and AMI hospital admissions in Copenhagen. The study period covered 1 January 1999-31 December 2006, stratified in warm (April - September and cold (October - March periods. A case-crossover epidemiology study design was applied. Models were adjusted for public holidays and influenza, confounding by PM10, NO2 and CO was investigated, the lag and non-linear effects of Tappmax was examined, effect modification by age, sex and SES was explored, and the results of the case-crossover models were compared to those of the generalised additive Poisson time-series and generalised estimating equation models. Results 14 456 AMI hospital admissions (12 995 people occurred during the study period. For an inter-quartile range (6 or 7°C increase in the 5-day cumulative average of Tappmax, a 4% (95% CI:-2%; 10% and 9% (95% CI: 3%; 14% decrease in the AMI admission rate was observed in the warm and cold periods, respectively. The 19-65 year old group, men and highest SES group seemed to be more susceptible in the cold period. Conclusion An increase in Tappmax is associated with a decrease in AMI admissions during the colder months.

    Like most other places, European metropolitan areas will face a range of climate-related challenges over the next decades that may influence the nature of urban life across the continent. Under future urbanization and climate change scenarios the well-being and comfort of the urban population might become progressively compromised. In urban areas, the effects of the warming climate will be accelerated by combination of Urban Heat Island effect (UHI) and extreme heat waves. The land cover composition directly influences atmospheric variability, and can either escalate or downscale the projected changes. Vegetation, forest ecosystems in particular, are anticipated to play an important role in modulating local and regional climatic conditions, and to be vital factor in the process of adapting cities to warming climate. This study investigates the impact of forest and land-cover change on formation and development of temperature regimes in the Copenhagen Metropolitan Area (CPH-MA). Potential to modify the UHI effect in CPH-MA is estimated. Using 2009 meteorological data, and up-to-date 2012 high resolution land-cover data we employed the online integrated meteorology-chemistry/aerosols Enviro-HIRLAM (Environment - High Resolution Limited Area Model) modeling system to simulate air temperature (at 2 meter height) fields for a selected period in July 2009. Employing research tools (such as METGRAF meteorological software and Geographical Information Systems) we then estimated the influence of different afforestation and urbanization scenarios with new forests being located after the Danish national afforestation plan, after proximity to the city center, after dominating wind characteristics, and urbanization taking place as densification of the existing conurbation. This study showed the difference in temperature up to 3.25°C, and the decrease in the spatial extent of temperature fields up to 68%, depending on the selected scenario. Performed simulations demonstrated

    The aims of the present study were threefold: to examine the distribution of knee joint osteoarthritis in a large, standardized radiological study; to examine the relationships between self reported knee pain and radiological OA; and to examine the natural history of radio-morphological change over age in individuals without radiological features of OA. The Copenhagen Osteoarthritis Study - COS is a substudy of the Copenhagen City Heart Study, a longitudinal regional health survey. From the third inclusion of the CCHS (1992-1994) 4,151 subjects were selected for subsequent standardized radiography of the pelvis, the knees, the hands, the wrists, and the lumbar spine. Images were analyzed and knee joint osteoarthritis (OA) was classified according to the radiographic atlas of Kellgren and Lawrence. Joint space width (JSW) was measured at three sites within both the medial and the lateral compartment. For the entire cohort the prevalence of radiological knee joint OA of all grades was 38.7% for men and 44.2% for women. Age stratification documented increasing knee joint OA both in regard to prevalence and morphological severity. Knee pain was universally correlated to the Kellgren and Lawrence severity of OA. In a subgroup with no features of radiological OA, a significant and linear decline in JSW with increasing age was found. We found a clear relationship between self-reported knee pain and radiological osteoarthritis. Pain was proportionally related to the severity of change. We also demonstrated a significant diminishing of joint space width with increasing age in individuals without apparent radiological degeneration. (orig.)

    Psychosocial risks are now widely recognised as one of the biggest challenges for occupational safety and health (OSH) and a major public health concern. The aim of this paper is to investigate the Portuguese long version of the Copenhagen Psychosocial Questionnaire II (COPSOQ II), in order to analyse the psychometric properties of the instrument and to validate it. The Portuguese COPSOQ II was issued to a total of 745 Portuguese employees from both private and public organisations across several economic sectors at a baseline and then 2 weeks later. Methodological quality appraisal was based on COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) recommendations. An analysis of the psychometric properties of the long version of COPSOQ II (internal consistency, intraclass correlation coefficient, floor and ceiling effects, response rate, missing values, mean and standard deviation, exploratory factor analysis) was performed to determine the validity and reliability of the instrument. The COPSOQ II had a response rate of 60.6% (test) and a follow-up response rate of 59.5% (retest). In general, a Cronbach's alpha of the COPSOQ scales (test and retest) was above the conventional threshold of 0.70. The test-retest reliability estimated by the intraclass correlation coefficient (ICC) showed a higher reliability for most of the scales, above the conventional 0.7, except for eight scales. The proportion of the missing values was less than 1.3%, except for two scales. The average scores and standard deviations showed similar results to the original Danish study, except for eight scales. All of the scales had low floor and ceiling effects, with one exception. Overall, the exploratory factor analysis presented good results in 27 scales assuming a reflective measurement model. The hypothesized factor structure under a reflective model was not supported in 14 scales and for some but not all of these scales the explanation may be a formative

    Typhoid fever is a systemic illness which in high-income countries mainly affects travellers. The incidence is particularly high on the Indian subcontinent. Travellers who visit friends and relatives (VFR) have been shown to have a different risk profile than others. We wished to identify main characteristics for travellers infected with S. Typhi considering both clinical and laboratory findings in order to provide for faster and better diagnostics in the future. The outcome of treatment, especially concerning relapse, was evaluated as well. Retrospectively collected data from 19 adult cases of typhoid fever over a 5-year period at the Department of Infectious Diseases, Copenhagen University Hospital, Hvidovre Denmark. The patients were young adults, presenting with symptoms within a month after travelling. 84% were returned from travelling in the Indian subcontinent. 17 out of 19 patients were VFR-travellers. The main symptoms were fever (100%), gastrointestinal symptoms (84%), headache (58%) and dry cough (26%). Laboratory findings showed elevated C-reactive protein (CRP) and lactate dehydrogenase (LDH) in all cases and elevated alanine transaminase (ALAT) in 47% of cases. In primary cases 4 isolates were fully susceptible to ciprofloxacin, the remaining were intermediate susceptible. Relapse occurred in 37% of the cases and only in cases where the patient was infected by a strain with intermediate susceptibility. Better pre-travel counselling should be given to VFR-travellers. The main symptoms and laboratory findings confirm previous findings. The relapse rate was unexpected high and could be correlated to ciprofloxacin-resistance.

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

    Atrial fibrillation (AF) is the most frequently encountered cardiac arrhythmia. It is a risk factor for stroke and premature death. We studied the temporal changes in the prevalence of AF from 1976 to 1994 in a random population aged 50 to 89 years. The prevalence of AF, diagnosed from electrocardiograms (ECGs), was determined in 8,606 patients examined in 1976 to 1978, in 8,943 patients examined in 1981 to 1983, and in 6,733 subjects examined in 1991 to 1994. Changes in prevalence of AF were estimated by logistic regression analysis. In men, the age-standardized prevalence of AF increased from 1.4% in 1976 to 1978 (odds ratio [OR] 1.0, reference) to 1.9% in 1981 to 1983 (OR 1.6, 95% confidence interval [CI] 1.1 to 2.1), and to 3.3% in 1991 to 1994 (OR 2.3, 95% CI 1.6 to 3.4, p<0.001, adjusted for age). In women, the prevalence of AF decreased from 1.5% in 1976 to 1978 (OR 1.0, reference) to 1.0% in 1981 to 1983 (OR 0.7, 95% CI 0.5 to 1.0), and to 1.1% in 1991 to 1994 (OR 0.7, 95% CI 0.5 to 1.0), although the overall decrease was not significant (p=0.11, adjusted for age). After adjusting for changes in comorbidity, body weight, and height, the increase in the prevalence of AF in men from 1976 to 1978 and from 1991 to 1994 remained significant (OR 1.9, 95% CI 1.3 to 2.8, p=0.002). Although unchanged in women, the prevalence of AF in men more than doubled from the 1970s to the 1990s. The factors responsible for this gender-specific increase in the prevalence of this common arrhythmia have yet to be identified.

    Full Text Available Abstract Background The molecular basis for the genetic risk of ischemic stroke is likely to be multigenic and influenced by environmental factors. Several small case-control studies have suggested associations between ischemic stroke and polymorphisms of genes that code for coagulation cascade proteins and platelet receptors. Our aim is to investigate potential associations between hemostatic gene polymorphisms and ischemic stroke, with particular emphasis on detailed characterization of the phenotype. Methods/Design The Ischemic Stroke Genetic Study is a prospective, multicenter genetic association study in adults with recent first-ever ischemic stroke confirmed with computed tomography or magnetic resonance imaging. Patients are evaluated at academic medical centers in the United States and compared with sex- and age-matched controls. Stroke subtypes are determined by central blinded adjudication using standardized, validated mechanistic and syndromic classification systems. The panel of genes to be tested for polymorphisms includes β-fibrinogen and platelet glycoprotein Ia, Iba, and IIb/IIIa. Immortalized cell lines are created to allow for time- and cost-efficient testing of additional candidate genes in the future. Discussion The study is designed to minimize survival bias and to allow for exploring associations between specific polymorphisms and individual subtypes of ischemic stroke. The data set will also permit the study of genetic determinants of stroke outcome. Having cell lines will permit testing of future candidate risk factor genes.

    Conclusions : Adherence to Mediterranean diet or DASH diet and increasing the consumption of antioxidant, vitamins, potassium, calcium food sources, vegetables, fruits, and whole grains intake can lower the risk of stroke. Healthy diet is effective in reducing risk of stroke, however, more studies need to be carried out in this area.

    Full Text Available Background The genetic epidemiology of ischemic stroke remains relatively unstudied, and information about the genetic epidemiology of ischemic stroke in populations with significant minority representation is currently unavailable. Methods The Brain Attack Surveillance in Corpus Christi project (BASIC is a population-based stroke surveillance study conducted in the bi-ethnic community of Nueces County, Texas, USA. Completed ischemic strokes were identified among patients 45 years or older seen at hospitals in the county between January 1, 2000 – December 31, 2002. A random sample of ischemic stroke patients underwent an in-person interview and detailed medical record abstraction (n = 400. Outcomes, including initial stroke severity (NIH stroke scale, age at stroke onset, 90-day mortality and functional outcome (modified Rankin scale ≥2, were studied for their association with family history of stroke among a first degree relative using multivariable logistic and linear regression. A chi-square test was used to test the association between family history of stroke and ischemic stroke subtype. Results The study population was 53.0% Mexican American and 58.4% female. Median age was 73.2 years. Forty percent reported a family history of stroke among a first degree relative. Family history of stroke was borderline significantly associated with stroke subtype (p = 0.0563. Family history was associated with poor functional outcome in the multivariable model (OR = 1.87; 95% CI: 1.14–3.09. Family history was not significantly related to initial stroke severity, age at stroke onset, or 90-day mortality. Conclusion Family history of stroke was related to ischemic stroke subtype and to functional status at discharge. More research is needed to understand whether stroke subtype would be a useful selection criterion for genetic association studies and to hypothesize about a possible genetic link to recovery following ischemic stroke.

    One established risk factors for testicular cancer is cryptorchidism. However, it remains unclear whether cryptorchidism is a risk factor in itself or whether the two conditions share common causes in early life (estrogen hypothesis), such as birth weight and birth order. The objective of this study is to utilize data from the Copenhagen School Health Records Register (CSHRR) to evaluate cryptorchidism, birth weight and birth order as risk factors for testicular cancer. The study population consisted of 408 cases of testicular cancer identified by a government issued identification number linkage of the entire CSHRR with the Danish Cancer Registry and a random subsample of 4819 males from the CSHRR. The study design was case-cohort and the period of follow-up between 2 April 1968 and 31 December 2003. Cryptorchidism was significantly associated with testicular cancer in crude analyses [hazard ratio (HR) = 3.60, 95% CI 2.79-4.65]. Birth weight was inversely associated with testicular cancer and no clear association with birth order was observed. The positive association between cryptorchidism and testicular cancer was only slightly attenuated controlling for birth weight and birth order and stratified on birth cohort (HR = 3.46, 95% CI 2.67-4.48). This study confirmed the robustness of the association between cryptorchidism and testicular cancer even after adjustment for birth weight and birth order. Furthermore, the study showed an inverse association between birth weight and testicular cancer.

    2003-01-01

    The documentary "The Copenhagen Fallout" recounts the friendship and "falling out" of Niels Bohr and Werner Heisenberg, two of the greatest contemporary physicists - friends whom war turned into enemies. It will be shown at CERN on 1st December. During a lecture in Germany towards the end of 1922, a 20-year-old physicist dared to interrupt Physics Nobel-Prize winner Niels Bohr with the words "There is a mathematical error in what you have said." The young scientist in question was none other than Werner Heisenberg. From this audacious beginning a fruitful collaboration and great friendship grew. But World War II threw up a wall of incomprehension between the two scientists, as one worked for the Nazi regime and the other opened his Copenhagen institute to German Jewish scientists. Then came their famous meeting in September 1941, dramatised by the no less famous play "Copenhagen", currently being performed in association with CERN at th...

    Full Text Available An agreement on reducing emissions from avoided deforestation and degradation at the UNFCCC Conference of the Parties 15 (COP 15 in Copenhagen December 2010 was not forthcoming. For a number of reasons this is a welcome outcome as several important outstanding legal and technical issues remain unresolved. This article examines the results from COP 15 including the Copenhagen Accord. It focuses on the key issues of principles, finance models, and environmental and social safeguards. It concludes with an assessment of the potential effect that the COP 15 will have on REDD negotiations this coming year prior to the UNFCCC COP 16 in Mexico December 2010.

    Full Text Available The Copenhagen Psychosocial Questionnaire (COPSOQ II includes scales for measuring 'workplace social capital'. The overall aim of this article is to evaluate the content validity of the following scales: horizontal trust, vertical trust and justice based on data from cognitive interviews using a think-aloud procedure. Informants were selected to achieve variation in gender, age, region of residence, and occupation. A predetermined coding scheme was used to identify: 1 Perspective (reflection on behalf of oneself only or abstraction to a broader perspective, 2 Use of response options, 3 Contexts challenging the process of answering, and 4 Overall reflections included in the retrieval and judgement processes leading to an answer for each item. The results showed that 1 the intended shift from individual to a broader perspective worked for eight out of eleven items. 2 The response option balancing in the middle covered different meanings. Retrieval of information needed to answer constituted a problem in four out of eleven items. 3 Three contextually challenging situations were identified. 4 For most items the reflections corresponded well with the intention of the scales, though the items asking about withheld information caused more problems in answering and lower content validity compared to the other items of the scales. In general, the findings supported the content validity of the COPSOQ II measurement of workplace social capital as a group construct. The study opens for new insight into how concepts and questions are understood and answered among people coming from different occupations and organizational settings.

    We examined the impact of major earthquakes on acute stroke admissions by a retrospective review of stroke admissions in the 6 weeks following the 4 September 2010 and 22 February 2011 earthquakes. The control period was the corresponding 6 weeks in the previous year. In the 6 weeks following the September 2010 earthquake there were 97 acute stroke admissions, with 79 (81.4%) ischaemic infarctions. This was similar to the 2009 control period which had 104 acute stroke admissions, of whom 80 (76.9%) had ischaemic infarction. In the 6 weeks following the February 2011 earthquake, there were 71 stroke admissions, and 61 (79.2%) were ischaemic infarction. This was less than the 96 strokes (72 [75%] ischaemic infarction) in the corresponding control period. None of the comparisons were statistically significant. There was also no difference in the rate of cardioembolic infarction from atrial fibrillation between the study periods. Patients admitted during the February 2011 earthquake period were less likely to be discharged directly home when compared to the control period (31.2% versus 46.9%, p=0.036). There was no observable trend in the number of weekly stroke admissions between the 2 weeks leading to and 6 weeks following the earthquakes. Our results suggest that severe psychological stress from earthquakes did not influence the subsequent short term risk of acute stroke, but the severity of the earthquake in February 2011 and associated civil structural damages may have influenced the pattern of discharge for stroke patients.

    This study aimed to elucidate associations between stroke onset and severity as well as chronotype (phase of entrainment) and internal time of stroke. Fifty-six first-ever ischemic stroke patients participated in a cross-sectional study assessing chronotype (mid-sleep on work-free days corrected for sleep deficit on workdays; MSFsc) by applying the Munich ChronoType Questionnaire (MCTQ). The MCTQ was completed twice, on average 68 ± 24 (SD) days post stroke and retrospectively for the time before stroke. To assess the impact of stroke in relation to internal time, InTstroke was calculated as MSFsc minus local time of stroke. Stroke severity was assessed via the standard clinical National Institute Health Stroke Scale (NIHSS) and modified Ranking Scale (mRS), both at hospital admission and discharge. Overall, most strokes occurred between noon and midnight. There was no significant association between MSFsc and stroke onset. MSFsc changed significantly after stroke, especially in patients with more severe strokes. Changes in MSFsc varied with InTstroke - the earlier the internal time of a stroke relative to MSFsc-before-stroke, the more MSFsc advanced after stroke. In addition, we provide first evidence that MSFsc changes varied between stroke locations. Larger trials are needed to confirm these findings.

    Introduction Depression is highly prevalent after stroke, and may influence recovery. We aimed to determine whether depressed mood acutely after stroke predicts subsequent disability and mortality. Methods As part of the Northern Manhattan Stroke Study, a population-based incident stroke case follow-up study performed in a multiethnic urban population, participants were asked about depressed mood within 7–10 days after stroke. Participants were followed every 6 months the first 2 years, and yearly thereafter for 5 years, for death and disability measured by the Barthel Index (BI). We fitted polytomous logistic regression models using canonical link to examine the association between depressed mood after stroke and disability, comparing moderate (BI 60–95) and severe (BI stroke was asked in 340 of 655 ischemic stroke patients enrolled, and 139 reported that they felt depressed. In multivariate analyses controlling for socio-demographic factors, stroke severity, and medical conditions, depressed mood was associated with a greater odds of severe disability compared to no disability at one (OR 2.91, 95% CI 1.07–7.91) and two years (OR 3.72, 95% CI 1.29–10.71) after stroke. Depressed mood was not associated with all cause mortality or vascular death. Conclusion Depressed mood after stroke is associated with disability but not mortality after stroke. Early screening and intervention for mood disorders after stroke may improve outcomes and requires further research. PMID:20671256

    Work in dialysis facilities involves long term contact with chronically ill patients. International comparisons make it clear that dialysis work is being concentrated, staff is being reduced and more patients are being treated. It is more than 20 years since the last German publication on job strains and job satisfaction experienced by dialysis staff was published. The present study examines the stress and strain currently experienced by the staff of German dialysis facilities. The staff of 20 dialysis facilities were surveyed with the Copenhagen Psychosocial Questionnaire (COPSOQ). The questionnaire was extended by adding dialysis-specific questions. The data from the dialysis facilities were assessed by comparison with other professions in medical care - nurses and geriatric nurses - using data recorded in the German COPSOQ database. A total of 367 employees took part in the study, corresponding to a response rate of 55%. For almost all psychosocial aspects, the dialysis staff regarded the stress and strain as being more critical than did the geriatric nurses. There were some positive differences in comparison to hospital nursing, including less conflict between work and private life. However, there were also negative differences, such as fewer possibilities of influencing the work. The results of the study show that dialysis work exhibits both positive and negative aspects in comparison with other healthcare professions. The results in the different facilities were highly variable, indicating that the deficits found in the individual scales are not inevitable consequences of working in dialysis in general, but are influenced and might be favourably altered by the individual facilities.

    In our quantum mechanics courses, measurement is usually taught in passing, as an ad-hoc procedure involving the ugly collapse of the wave function. No wonder we search for more satisfying alternatives to the Copenhagen interpretation. But this overlooks the fact that the approach fits very well with modern measurement theory with its notions of the conditioned state and quantum trajectory. In addition, what we know of as the Copenhagen interpretation is a later 1950s development and some of the earlier pioneers like Bohr did not talk of wave function collapse. In fact, if one takes these earlier ideas and mixes them with later insights of decoherence, a much more satisfying version of Copenhagen quantum mechanics emerges, one for which the collapse of the wave function is seen to be a harmless book keeping device. Along the way, we explain why chaotic systems lead to wave functions that spread out quickly on macroscopic scales implying that Schrödinger cat states are the norm rather than curiosities generated in physicists' laboratories. We then describe how the conditioned state of a quantum system depends crucially on how the system is monitored illustrating this with the example of a decaying atom monitored with a time of arrival photon detector, leading to Bohr's quantum jumps. On the other hand, other kinds of detection lead to much smoother behaviour, providing yet another example of complementarity. Finally we explain how classical behaviour emerges, including classical mechanics but also thermodynamics.

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

    Transient elevated blood pressure (BP) is frequent in patients presenting with acute ischemic stroke. The pathophysiology of this response is not clear and its effect on clinical outcome has shown contradictory results. Some studies have suggested that BP elevation may represent a protective response to enhance perfusion in ischemic brain tissue. In this study, we aimed to explore the association between elevated admission BP and stroke severity in the acute phase of ischemic stroke. If it is true that elevated BP represents a protective response in acute ischemia, we expected an inverse association between elevated BP and admission stroke severity, and a positive association between elevated BP and complete neurological recovery within 24 h and/or favorable short-term outcome. Patients with ischemic stroke with hospital admission stroke registry (Bergen NORSTROKE Registry). BP was measured immediately after admission in all patients. Elevated BP was defined as systolic BP ≥140 mm Hg or diastolic BP ≥90 mm Hg. The National Institutes of Health Stroke Scale (NIHSS) was used to assess stroke severity upon admission. Mild stroke was defined as NIHSS score stroke as NIHSS score 8-14, and severe stroke as NIHSS score ≥15. Complete neurological recovery (CNR) was defined as no persistent ischemic stroke symptoms at 24 h after admission. Favorable short-term outcome was defined as a modified Rankin Scale score of 0 or 1 at day 7. A total of 749 patients with ischemic stroke were included, of which 621 patients (82.9%) presented with elevated BP. Elevated BP was independently associated with mild stroke (odds ratio, OR: 2.12; 95% CI: 1.39-3.24; p stroke (OR: 0.41; 95% CI: 0.25-0.68; p stroke severity on admission, where elevated BP was associated with mild stroke and lack of elevated BP was associated with severe stroke. This could be explained by a protective effect of elevated BP in the acute phase of ischemic stroke, although the absence of association between

    Why did Werner Heisenberg, a participant in the nuclear research programme of the Third Reich, visit his friend and mentor Niels Bohr in occupied Denmark in September 1941? Was it a deliberate attempt to mislead the allies through talking to Bohr? Or was he really pursuing the utopian goal of halting the race to build the atomic bomb? What the historians have never been able to fully explain is explored in the play "Copenhagen", in which the ghosts of the two great scientists try to fathom why they failed to understand each other all those years ago. "Copenhagen", which has filled theatres in London, New York and Paris, is one of the most successful plays of British author Michael Frayn, also famous for his crime thrillers and comedies.

    Objective Acute stroke is a serious concern in Emergency Department (ED) dizziness presentations. Prior studies, however, suggest that stroke is actually an unlikely cause of these presentations. Lacking are data on short- and long-term follow-up from population-based studies to establish stroke risk after presumed non-stroke ED dizziness presentations. Methods From 5/8/2011 to 5/7/2012, patients ≥ 45 years of age presenting to EDs in Nueces County, Texas, with dizziness, vertigo, or imbalance were identified, excluding those with stroke as the initial diagnosis. Stroke events after the ED presentation up to 10/2/2012 were determined using the Brain Attack Surveillance in Corpus Christi (BASIC) study, which uses rigorous surveillance and neurologist validation. Cumulative stroke risk was calculated using Kaplan-Meier estimates. Results 1,245 patients were followed for a median of 347 days (IQR 230- 436 days). Median age was 61.9 years (IQR, 53.8-74.0 years). After the ED visit, fifteen patients (1.2%) had a stroke. Stroke risk was 0.48% (95% CI, 0.22%-1.07%) at 2 days; 0.48% (95% CI, 0.22%-1.07%) at 7 days; 0.56% (95% CI, 0.27%-1.18%) at 30 days; 0.56% (95% CI, 0.27%-1.18%) at 90 days; and 1.42% (95% CI, 0.85%-2.36%) at 12 months. Interpretation Using rigorous case ascertainment and outcome assessment in a population-based design, we found that the risk of stroke after presumed non-stroke ED dizziness presentations is very low, supporting a non-stroke etiology to the overwhelming majority of original events. High-risk subgroups likely exist, however, because most of the 90-day stroke risk occurred within 2-days. Vascular risk stratification was insufficient to identify these cases. PMID:24788511

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

    Full Text Available Abstract Background Stroke has a considerable socio-economic impact worldwide and is the leading cause of disabilities in the Western world. Economic studies of stroke focus merely on physical aspects and clinical interventions. To our current knowledge there is no comprehensive economic study investigating the economic impact of stroke including psychological and social aspects. The €-Restore4Stroke project, part of a large comprehensive research programme Restore4Stroke, aims to investigate the total economic impact of stroke in the Netherlands. Methods Two trial-based economic evaluation studies will be conducted within the €-Restore4Stroke project: one focussing on a self-management intervention and one on an augmented cognitive behavioural therapy intervention. Both include cost-effectiveness analyses and cost-utility analyses as primary research methods. Furthermore, a cost-of-illness study investigating costs after stroke attached to a cohort study and a record linkage study in which four databases are linked to investigate patterns of health care consumption before and after stroke, are embedded in €-Restore4Stroke. All studies will be performed from a societal perspective. The primary outcome measure for the cost-effectiveness analysis is the increase in health status on the primary outcome scales. Within the cost-utility analysis, the primary outcome measure is quality-adjusted life years (QALYs for which an indirect preference-based technique will be used. In the self-management study we will also look at the estimation of health effects on informal caregivers. Cost outcomes in the cost-of-illness study will be computed with a cost questionnaire and linkage of several databases will be used to derive outcomes in the record linkage study, Discussion €-Restore4Stroke will provide new insights and evidence for the economic impact of psychosocial consequences after stroke. Besides being innovative in various ways (i.e. focussing

    Full Text Available Abstract : The theory of the effects of all human souls on external objects, from the viewpoint of Copenhagen School (in Quantum Physics, has made physicists deny the existence of two separate realms of the observer and the observed; they claim that causality is meaningless and profess that it is impossible to recognize the object. While, on the other hand, Mulla Ṣadra believes that the effect of soul on external objects is limited to the souls of prophets as well as saints and, barring evil eye or supplications, there is no such effect in others. In this article we argue that, based on Mulla Ṣadra’s teachings and philosophical doctrine, it is actually possible to generalize this effect to other human souls. Consequently, it is impossible to have an accurate recognition of the causes of events if causality is considered meaningless. In addition, it is feasible to have cognition about these causes of events through gnostic intuition.Keywords : human soul, external objects, Copenhagen School, Mulla Ṣadra, unity, causality Abstrak :  Teori tentang efek jiwa seluruh manusia terhadap objek-objek eksternal, dari sudut pandang Madzhab Copenhagen (dalam Fisika Kuantum, telah membuat para fisikawan mengingkari keterpisahan dua alam, yaitu subjek dan objek; berdasarkan keyakinan ini, mereka mengklaim bahwa [hukum] kausalitas menjadi gugur dan tidak berguna, dan mereka juga percaya bahwa mengetahui sepenuhnya objek adalah tidak mungkin. Sementara, di tempat lain, Mulla Ṣadra meyakini bahwa jiwa yang berefek terhadap objek-objek eksternal terbatas pada jiwa para nabi dan orang-orang suci. Ia juga meyakini bahwa tidak berefeknya jiwa-jiwa manusia biasa kecuali pada perbuatan-perbuatan seperti yang ia sebut sebagai ‘evil eye’ dan doa.

    A combined air/liquid solar collector system was retrofitted to a three-storey apartment building in Copenhagen, originally built in the 1950s. The building has been insulated outside with 100 mm mineral wool. Between the insulation and the original walls there is an air gap. In this air gap the hot air from the solar air collector is circulated to heat the building. Site-built combined air/liquid collectors cover the whole south- facing roof. The collectors were built on top of the existing roof, which serves as the back of the collectors. The solar air system is a dual system, including both a closed collector loop to an air to water heat exchanger and a double envelope. (author)

    Bakstim, a new biostimulating preparation obtained from the organs of the immune system of animals, was developed. The impact of Bakstim on the growth and toxigenic function of C. tetani production strain Copenhagen-471 was evaluated. The addition of the preparation to Gluzman commercial medium for obtaining tetanus toxoid led to an increase in the yield of bacterial biomass from 1.9 to 4-fold and an increase in the toxoid production from 2 to 2.8-fold. The optimum concentration of this biostimulant ensuring the maximum yield of tetanus toxin from the production culture was determined (1,000 mg/l). Bakstim will supposedly be used as additive to nutrient media for the production of tetanus toxoid.

    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.

  4. Study and Analysis of Six Stroke Engine

    B. Ramya

    2014-09-01

    Full Text Available Six Stroke engine, the name itself indicates a cycle of six strokes out of which two are useful power strokes. According to its mechanical design, the six-stroke engine with external and internal combustion and double flow is similar to the actual internal reciprocating combustion engine. However, it differentiates itself entirely, due to its thermodynamic cycle and a modified cylinder head with two supplementary chambers: combustion and an air heating chamber, both independent from the cylinder. In this the cylinder and the combustion chamber are separated which gives more freedom for design analysis. In addition to the two valves in the four stroke engine two more valves are incorporated which are operated by a piston arrangement. The Six Stroke is thermodynamically more efficient because the change in volume of the power stroke is greater than the intake stroke and the compression stroke. The main advantages of six stroke engine includes reduction in fuel consumption by 40%, two power strokes in the six stroke cycle, dramatic reduction in pollution, adaptability to multi fuel operation. Six stroke engine’s adoption by the automobile industry would have a tremendous impact on the environment and world economy .

    The aim of this article is to describe the need for assistive devices and environmental modifications among long-living stroke survivors and to investigate if the need is continued and growing over time. The study sample of 155 consecutive stroke patients with stroke-related impairment, discharged...... home from three hospitals in Copenhagen from 1996 through 1998, constituted 20% of the total population of stroke survivors in this area. The results showed that 75% of these patients were provided with assistive devices and/or environmental modifications at discharge. Six months after discharge...... be required in order to target stroke survivors' changing needs for assistive devices and environmental modifications....

    This study aimed to compare the prevalence of stroke risk factors among people with a parental history of stroke to those in a control group of individuals, of similar age, gender and social class, with no parental stroke history. Parental stroke increases an individual's risk of stroke, but little is known of the potential value of using this information in targeted screening for primary prevention in general practice. We sent questionnaires to 300 randomly selected individuals aged 40-65 years, in each of 11 different general practices in Northern Ireland. Among 1061 responses received within six weeks, 332 reported a parental history of stroke (31.3%). We matched respondents with (cases) and without (controls) a parental history of stroke on characteristics of age, gender and socioeconomic status. Matched pairs were invited to attend a consultation at which their diet and exercise habits were assessed using validated questionnaires and height, weight, blood pressure and serum lipids and glucose were measured. Matched data were available for 199 case-control pairs (398 individuals). Mean systolic and diastolic blood pressures were significantly higher in cases than in paired controls (systolic 146.3 versus 140.6 mmHg (P pressure has potential value in identifying people likely to benefit from primary prevention, but do not support the adoption of a targeted screening strategy for other commonly cited stroke risk factors.

    2006-01-01

    Rationale: Low body mass index (BMI) is a marker of poor prognosis in chronic obstructive pulmonary disease (COPD). In the general population the harmful effect of low BMI is due to the deleterious effects of a low fat free mass index (FFMI, fat free mass/weight(2)). Objectives: We explored...... distribution of low FFMI and its association with prognosis in a population based cohort of COPD patients. Methods: We used data on 1,898 COPD patients identified in a population-based epidemiological study in Copenhagen. Fat free mass was measured using bioelectrical impedance analysis. Patients were followed...... the lowest FFMI 10(th) percentile of the general population. BMI and FFMI were significant predictors of mortality, independent of relevant covariates. Being in the lowest FFMI 10(th) percentile of the general population was associated with a hazard ratio of 1.5 (95% confidence interval 1.2-1.8) for overall...

    Prolongation of the PR interval has been associated with an increased risk of incident atrial fibrillation (AF). To determine if there was a nonlinear relation between PR interval duration and the risk of AF. We included 288,181 individuals, corresponding to one third of the population in the greater region of Copenhagen. These individuals had a digital electrocardiogram (ECG) recorded in a general practitioner's core facility from 2001 to 2010. Data on drug use, comorbidity, and outcomes were collected from Danish registries. During a median follow-up period of 5.7 years, 11,087 developed AF. Having a PR interval ≥95th percentile (≥196 ms for women, ≥204 ms for men) was associated with an increased risk of AF as evidenced by a multivariable-adjusted hazard ratio (HR) of 1.18 (95% confidence interval [CI] 1.06-1.30, P = .001) for women and 1.30 (1.17-1.44, P PR interval between 40th and 60th percentile). Having a short PR interval PR intervals for both women and men. With respect to short PR intervals, we also observed an increased risk of AF for women. Copyright © 2013 Heart Rhythm Society.

    INTRODUCTION: Studies of dietary habits show a high iodine intake in children in Denmark. Iodine excretion in children has not previously been assessed. Iodine excretion in adults is below the recommended threshold, and it is therefore being discussed to increase the fortification level. The main...... objective of this study was to assess iodine excretion in children living in Copenhagen to establish whether a moderate increase in iodine fortification would lead to excess iodine intake in this group. METHODS: Children in first and fifth grade were recruited through schools in Copenhagen. In total, 244...... children de-ivered a urine sample. Urine samples were analysed for iodine and creatinine, and the results were expressed as urinary iodine concentration (UIC) and as estimated 24-h iodine excretion. Iodine excretion in children was also compared with that of adults living in the same area, investigated...

    Full Text Available Abstract Background Mood disorder is recognised as an important and common problem after stroke but little is known about the longer term effects of mood on functional outcomes. This protocol paper describes the Stroke Outcomes Study 2 (SOS2, a research study conducted in two large acute NHS Trusts in the North of England, which was designed to investigate the impact of early depressive symptoms on outcomes after an acute stroke. Methods and design SOS2 was a prospective cohort study that aimed to recruit patients in the first few weeks after a stroke, and to follow them up at regular intervals for one year thereafter in order to describe the trajectory of psychological symptoms and study their impact on physical functional recovery. Measures of mood and function were completed at baseline (approximately 3 weeks and at four follow-up time-points: approximately 9, 13, 26 and 52 weeks after the index stroke. Discussion Recruiting patients to research studies soon after an acute stroke is difficult. Mortality following stroke is approximately 30% and in the region of half the patients that survive the initial event are significantly disabled. Together these factors reduced the number of patients available to participate in SOS2 but once recruited to the study the drop-out rate was relatively low. During the recruitment period over 6000 admissions for stroke or query stroke were screened for eligibility. A cohort of 592 study participants was finally achieved.

    OBJECTIVE: We tested the hypothesis that low plasma concentrations of 25-hydroxyvitamin D are associated with increased risk of symptomatic ischemic stroke in the general population. METHODS: We measured plasma 25-hydroxyvitamin D in 10,170 individuals from the general population, the Copenhagen...... City Heart Study. During 21 years of follow-up, 1,256 and 164 persons developed ischemic and hemorrhagic stroke, respectively. In a meta-analysis of ischemic stroke, we included 10 studies, 58,384 participants, and 2,644 events. RESULTS: Stepwise decreasing plasma 25-hydroxyvitamin D concentrations...... were associated with stepwise increasing risk of ischemic stroke both as a function of seasonally adjusted percentile categories and as a function of clinical categories of 25-hydroxyvitamin D (p for trend ≤ 2 × 10(-3) ). In a Cox regression model comparing individuals with plasma 25-hydroxyvitamin D...

    Study registries offer the opportunity to evaluate the effects of new therapies or to observe the consequences of new treatments in clinical practice. The SITS-MOST registry confirmed the validity of findings from randomized trials on intravenous thrombolysis concerning safety and efficacy in the clinical routine. Current study registries concerning new interventional thrombectomy techniques suggest a high recanalization rate; however, the clinical benefit can only be evaluated in randomized, controlled trials. Similarly, the experiences of the BASICS registry on basilar artery occlusion have led to the initiation of a controlled trial. The benefit of hemicraniectomy in malignant middle cerebral artery infarction has been demonstrated by the pooled analysis of three randomized trials. Numerous relevant aspects are currently documented in the DESTINY-R registry. Finally, the recently started RASUNOA registry examines diagnostic and therapeutic aspects of ischemic and hemorrhagic stroke occurring during therapy with new oral anticoagulants.

In India Community Surveys have shown a crude prevalence rate for hemiplegia 200 per 1, 00, 000 population. It accounts for nearly 1.5% of all urban admissions, 4.5 % of all medical and about 20% of neurological cases. AIMS AND OBJECTIVE: Identification of risk factors and evaluation of clinical profile of acute stroke. MATERIAL AND METHOD: INCLUSION CRITERIA: Cases of acute stoke admitted in SGMH hospital were selected for the study. EXCLUSION CRITERIA: Brain injury cases, infective, neoplastic cases producing stroke were excluded. RESULTS: Stroke was more common in male, 58 % patients were male and 42% patients were female. It was more common in 5th and 6th decade. Most common etiology was infarction. Most common risk factor was hypertension followed by smoking. In addition to limb weakness, headache and vomiting were most common presenting symptoms followed by convulsion. These symptoms were more common in hemorrhagic stroke. Right sided hemiplegia was more common than left sided. Middle cerebral artery was involved in majority of cases in atherothrombotic stroke whereas basal ganglion was most common site of bleed in hemorrhagic stroke. Coma and mortality were more in hemorrhagic stroke. CONCLUSION: The risk factors and clinical profile of acute stroke in India are similar to that of Western countries. Common risk factors are hypertension, smoking, diabetes mellitus and hyperlipidemia

    Preclinical studies suggest that stem cell therapy (SCT) may improve poststroke recovery, and clinical trials investigating safety are ongoing. However, knowledge about patients' attitudes to SCT in stroke is limited. We evaluated the knowledge and attitudes to this therapeutic approach as well as possible factors influencing this among stroke patients potentially suitable for SCT. Consecutive first-ever acute ischemic stroke patients aged 20-75 years with NIH stroke scale scores 1-18 were included. Exclusion criteria were severe comorbidities or infratentorial stroke. Clinical follow-up after 3-5 years assessed severity of residual stroke symptoms, cognitive function, functional status, patient-reported outcome, and comorbidity, and after receiving standardized information, the participants also completed an eight-item questionnaire on knowledge and attitudes about SCT. The relationships between clinical variables and positive attitude to SCT were assessed with logistic regression analyses. Of 108 patients included at baseline, 84 participated at follow-up and completed the questionnaire. In total, 12% had prior knowledge of SCT. When informed, 63% were positive toward it and 36% reported willingness to participate in SCT trials. Only 5%-8% expressed ethical considerations regarding different stem cell sources. Positive attitudes to SCT were associated with male gender (OR: 3.74; 95% CI: 1.45-9.61; P stroke patients had limited prior knowledge of SCT, yet attitudes were positive among the majority after receiving standardized and neutral information. Gender and degree of stroke recovery may influence attitudes to SCT, indicating a need for targeted information to improve knowledge about SCT.

    Full Text Available Numerous etiologies are responsible for cases of stroke in young adults. This study reviews the causes of two types of stroke (ischemic and intracerebral hemorrhage in young adults aged 15 to 40years, admitted to our center (a tertiary care center from 1997 to 2002. The purpose of this study is to determine the relative frequency of causes of stroke in young adults and compare this with published data in the literature. Using the codes 46.0 to 46.8 of the International Classification of Diseases- 10th Edition (ICD-10, cases were identified from the records of the stroke patients admitted in Imam Khomeini Hospital and the data were collected from their files using a comprehensive questionnaire. Forty-two cases of ischemic stroke (62% and 26 cases of intracerebral hemorrhage (38% were identified. The leading cause of ischemic stroke was cardioembolism (38.1%, followed by atherosclerosis in 5 cases (11.9%. Among cardiac causes infarction was attributable to consequences of rheumatic heart disease in 8 cases. In 3 cases a cessation or decrease in dose of warfarin was followed directly by an ischemic stroke. The most leading cause of intracerebral hemorrhage was hypertension (30.8%. Other causes were anticoagulant therapy, intratumoral hemorrhage, aplastic anemia, leukemia, arteriovenous malformations, and chronic active hepatitis. In conclusion, cardioembolism and hypertension were the most leading causes of ischemic and hemorrhagic stroke in young adults admitted in our hospital.

    Eosinophilia may represent an early paraclinical sign of malignant disease and a host anti-tumor effect. The association between eosinophilia and the development of solid tumors has never before been examined in an epidemiological setting. The aim of the present study was to investigate eosinophilia in routine blood samples as a potential biomarker of solid tumor development in a prospective design. From the Copenhagen Primary Care Differential Count (CopDiff) Database, we identified 356 196 individuals with at least one differential cell count (DIFF) encompassing the eosinophil count during 2000-2007. From these, one DIFF was randomly chosen and categorized according to no (eosinophilia. From the Danish Civil Registration System and the Danish Cancer Registry we ascertained all-cause death and solid tumors within the first three years following the DIFF. Using multivariable logistic regression, odds ratios (OR) were calculated and adjusted for previous eosinophilia, sex, age, year, month, C-reactive protein, previous cancer and Charlson's Comorbidity Index. The risk of bladder cancer was increased with mild eosinophilia [OR 1.93 (CI 1.29-2.89), p = 0.0013]. No associations with eosinophilia were observed for the remaining solid cancers. We demonstrate that eosinophilia in routine blood samples associates with an increased risk of bladder cancer. Our data emphasize that additional preclinical studies are needed in order to shed further light on the role of eosinophils in carcinogenesis, where it is still unknown whether the cells contribute to tumor immune surveillance or neoplastic evolution.

    To examine choroidal thickness in a population-based child cohort in relation to birth parameters. The Copenhagen Child Cohort 2000 Eye Study examined 1406 children aged 11 to 12 years using enhanced depth imaging spectral-domain optical coherence tomography (EDI-OCT), ocular biometry and measurement of height, weight, refraction, and self-reported pubertal development status. Birth parameters were obtained from the Danish Medical Birth Registry. The subfoveal choroid in low birth weight children (choroid in high birth weight children (>4500 g, n = 48, mean 351 ± 63 μm) was comparable with normal birth weight children, P = 0.44. The subfoveal choroid was thinner in preterm children, however the difference was not significant (-18 [-37 to 2] μm, P = 0.08). Small for gestation children had thinner subfoveal choroid (-19 [-37 to -1] μm, P = 0.04) compared with appropriate for gestation children. Longer birth length was associated with a thicker subfoveal choroid (2 [1-4] μm/cm, P = 0.005). Macular choroidal thickness at 16 extrafoveal locations was measured in a subset of children and found to have the same associations with birth weight as the subfoveal choroidal thickness. In 11- to 12-year-old children, thinner choroids were associated with lower birth weight, lower birth length, and being small for the gestational age.

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

    Full Text Available Abstract Background Each year, approximately 12,000 Australians of working age survive a stroke. As a group, younger stroke survivors have less physical impairment and lower mortality after stroke compared with older survivors; however, the psychosocial and economic consequences are potentially substantial. Most of these younger stroke survivors have responsibility for generating an income or providing family care and indicate that their primary objective is to return to work. However, effective vocational rehabilitation strategies to increase the proportion of younger stroke survivors able to return to work, and information on the key target areas for those strategies, are currently lacking. Methods/Design This multi-centre, three year cohort study will recruit a representative sample of younger ( Discussion The study is designed to identify targets for rehabilitation-, social- and medical-intervention strategies that promote and maintain healthy ageing in people with cardiovascular and mental health conditions, two of the seven Australian national health priority areas. This will rectify the paucity of information internationally around optimal clinical practice and social policy in this area.

    Abstract Background although variation in stroke service provision and outcomes have been previously investigated, it is less well known what service characteristics are associated with reduced short- and medium-term mortality. Methods data from a prospective multicentre study (2009–12) in eight acute regional NHS trusts with a catchment population of about 2.6 million were used to examine the prognostic value of patient-related factors and service characteristics on stroke mortality outcome at 7, 30 and 365 days post stroke, and time to death within 1 year. Results a total of 2,388 acute stroke patients (mean (standard deviation) 76.9 (12.7) years; 47.3% men, 87% ischaemic stroke) were included in the study. Among patients characteristics examined increasing age, haemorrhagic stroke, total anterior circulation stroke type, higher prestroke frailty, history of hypertension and ischaemic heart disease and admission hyperglycaemia predicted 1-year mortality. Additional inclusion of stroke service characteristics controlling for patient and service level characteristics showed varying prognostic impact of service characteristics on stroke mortality over the disease course during first year after stroke at different time points. The most consistent finding was the benefit of higher nursing levels; an increase in one trained nurses per 10 beds was associated with reductions in 30-day mortality of 11–28% (P stroke of higher numbers of trained nursing staff over and above that of other recognised mortality risk factors.

    To evaluate in the setting of a stroke unit ward the usefulness of a prolonged (>6 h) video-EEG recording (PVEEG) in identifying non-convulsive status epilepticus (NCSE) in patients with an acute ischemic stroke. Predictors of NCSE were also evaluated. Patients with an acute ischemic stroke, referred to our unit, were included in this prospective observational study. A PVEEG recording was implemented after stroke in all patients during the first week: (a) promptly in those exhibiting a clear or suspected epileptic manifestation; (b) at any time during the routine activity in the remaining patients. After the first week, a standard EEG/PVEEG recording was hooked up only in presence of an evident or suspected epileptic manifestation or as control of a previous epileptic episode. NCSE was identified in 32 of the 889 patients (3.6 %) included in the study. It occurred early (within the first week) in 20/32 (62.5 %) patients and late in the remaining 12. Diagnosis was made on the basis of a specific clinical suspect (n = 19, 59.4 %) or without any suspect (n = 13, 40.6 %). In a multivariate analysis, a significant association of NCSE was observed with NIHSS score, infarct size and large atherothrombotic etiology. NCSE is not a rare event after an acute ischemic stroke and a delayed diagnosis could worsen patient prognosis. Since NCSE can be difficult to be diagnosed only on clinical grounds, implementation of a prompt PVEEG should be kept available in a stroke unit whenever a patient develop signs, although subtle, consistent with NCSE.

    The December 2009 summit on climate change in Copenhagen was remarkable not because it ended in an ambitious deal to curb greenhouse gas emissions but because of the unprecedented number of journalists, delegates, NGOs and scientists present. In this wide-ranging study, the author has produced a detailed analysis of the coverage of the summit across the globe through studying more than 400 articles published in two print media in 12 countries.The analysis reveals that articles written principally about the science of climate change represented less than 10 per cent of all those surveyed. The study makes extensive use of official UN figures to produce the first detailed assessment of who actually attended Copenhagen. It also includes a survey of over 50 environmental journalists and scientists across the 12 target countries post-Copenhagen to ascertain how they think climate change science might be best communicated.

    Full Text Available Post stroke rehabilitation has been consistently reported in physiotherapy as being difficult to manage and limiting to rehabilitation outcome. It is reported that the first few months post stroke are crucial for rehabilitation to reach a maximum potential. However, after this period further recovery is unlikely. Specific, measurable, achievable, realistic, and time-framed (SMART goals are used for goal setting for rehabilitation. They can provide coordination between a multidisciplinary team to develop a plan for the individual needs of patients. This case study explored the use of SMART goals, which are often not used in a rehabilitation setting due to being time-consuming and difficult to create. This case report provides the first evidence that SMART goals may serve as a powerful tool for rehabilitation following stroke. The case study illustrates the clinical role of physiotherapists in the management of a patient with stroke. [J Exp Integr Med 2014; 4(1.000: 71-73

    Full Text Available : Ischemic stroke is the 3rd leading cause of death after AMI and cancer. Stroke is also the leading cause of hospital admission causing disability. The study was based on 100 patients with ischemic stroke admitted to the JJM Medical College, Davangere. This study was done to estimate the role of C-reactive protein as a marker of acute inflammation following ischemic stroke and also to determine, its prognostic role, by assessing the functional outcome of patient using modified Barthel index scoring (ADL. Patients with CRP 6 mg/dl suffered severe disease with poor functional outcome. P value <0.05, significant, suggests CRP is a good tool for prognostic indicator

    Aims The aim of this study was to investigate the impact of persistence and non-persistence in leisure time physical activity on coronary heart disease and all-cause mortality. Methods and results In the Copenhagen City Heart Study, we prospectively followed 12,314 healthy subjects for 33 years of maximum follow-up with at least two repeated measures of physical activity. The association between persistence and non-persistence in leisure time physical activity, coronary heart disease and all-cause mortality were assessed by multivariable Cox regression analyses. Coronary heart disease mortality for persistent physical activity in leisure compared to persistent sedentary activity were: light hazard ratio (HR) 0.76; 95% confidence interval (CI) 0.63-0.92, moderate HR 0.52; 95% CI 0.41-0.67, and high physical activity HR 0.51; 95% CI, 0.30-0.88. The differences in longevity were 2.8 years for light, 4.5 years for moderate and 5.5 years for high physical activity. A substantial increase in physical activity was associated with lower coronary heart disease mortality (HR 0.75; 95% CI 0.52-1.08) corresponding to 2.4 years longer life, whereas a substantial decrease in physical activity was associated with higher coronary heart disease mortality (HR 1.61; 95% CI 1.11-2.33) corresponding to 4.2 years shorter life than the unchanged group. A similar pattern was observed for all-cause mortality. Conclusion We found inverse dose-response relationships between persistent leisure time physical activity and both coronary heart disease and all-cause mortality. A substantial increase in physical activity was associated with a significant gain in longevity, whereas a decrease in physical activity was associated with even greater loss of longevity.

    To study the pattern of stroke in Kuwait, prospective data were collected from all patients admitted with first-ever stroke to our hospital over 3 years: 1989, 1992 and 1993. The primary-care registry over the same period was examined to ascertain that all cases of stroke seen by the primary-care doctors were referred to a hospital. Death certificates issued for people who died outside the hospital were also examined. The study included: clinical evaluation, computed tomography, electrocardiography, blood laboratories, serum chemistry and other investigations as required. The overall annual crude incidence rate was 27.6/100,000 population. The age-adjusted annual crude incidence rate was 145.6/100,000 population. No seasonal variation in the stroke incidence was observed in our study. Carotid-territory large infarction represented 46.5% of all strokes followed by intracerebral haemorrhage in 19.9%, lacunar infarction in 17%, basilar infarction in 8.3% and subarachnoid haemorrhage in 1.7%. The overall case fatality rate was 10%. Mortality increased with age and when loss of consciousness was present. The study demonstrated that stroke incidence in Kuwait is very low due to the young average age of the Kuwaiti population.

    This study examined the effectiveness of a slide/audio community education program aimed at increasing knowledge of stroke risk factors, stroke warning signs, and action needed when stroke warning signs occur. The program targets audiences at higher risk for stroke, especially individuals who are black or >50 years of age. Subjects were 657 adults living in the community or in senior independent-living settings. The study examined the effectiveness of the program when presented alone and when accompanied by discussion (facilitation) led by a trained individual. Knowledge of stroke risk factors and warning signs was assessed using parallel pretests and posttests developed and validated specifically for the study. ANCOVA indicated that neither pretesting nor facilitation had a significant effect on posttest measures of knowledge. Paired t tests of groups receiving both the pretest and posttest demonstrated significant increase in knowledge (mean increase, 10.87%; Peducational level. No significant differences could be ascribed to facilitation. The data indicate that the slide/audio program is effective in increasing knowledge of stroke risk factors, warning signs, and necessary action in subjects of varying ages, races, and education. Pretesting and facilitation did not significantly affect the short-term acquisition of information. The slide/audio program appears to offer a short, easily used educational experience for diverse communities, whether as a stand-alone program or with facilitated discussion.

    Full Text Available The automotive frames that can be created consciously with three-dimensional freehand strokes are quite important and useful in the early stage of automotive styling. However, all the strokes are drawn on the screen in two-dimensional. This study focuses on the creation of three-dimensional freehand strokes by applying the interpolation algorithm in two orthogonal planes, the projection algorithm and the resultant matrix algorithm. The fitting algorithms of strokes have been developed as the bridges between the traditional two-dimensional sketching and three-dimensional digital modeling. The stylists could use the digital tablet and pen to sketch the frames or outlines of a vehicle in three-dimensional space and then those could be used for establishing the automotive surfaces in any engineering software.

  20. Morbidity and Mortality in 7,684 Women According to Personal Hair Dye Use: The Copenhagen City Heart Study followed for 37 Years

    Science.gov (United States)

    2016-01-01

    Background Permanent hair dye contains aromatic amines which are carcinogenic, and can cause allergic skin reactions. In the long term personal use of hair dye might therefore influence both morbidity and mortality. Objectives We tested the hypothesis that personal use of hair dye in women is associated with increased morbidity and mortality in the general population. Methods We included 7,684 women from the Copenhagen City Heart Study with information on the use of personal hair dye. We assessed the risk of cancer, skin diseases, other morbidities, and mortality during a median follow-up of 27 years (range 0–37). Results The multivariable adjusted hazard ratio for malignant melanoma in women with versus without personal use of hair dye was 2.07 (95% confidence interval 1.25–3.42). There was no increased risk of other cancer types. For other skin diseases and other major causes of morbidity we found no differences between the two groups, except for a minor excess of digestive diseases and increased risk of Parkinson’s disease among women using hair dye. Finally, we found no difference in all-cause mortality comparing women using personal hair dye or not. After correction for multiple comparisons, none of the results remained significant. However, in sensitivity analysis the excess risk of malignant melanoma remained increased with a hazard ratio of 2.58 (95%CI 1.33–5.03) among users of personal hair dye. Conclusions Personal use of hair dye does not have major influences on morbidity and mortality. Our finding of a 2-fold risk of malignant melanoma in women using hair dye is hypothesis generating.

    Objective Evolutionary stroke is one common and important subgroup of acute ischemic stroke with nerve damage symptoms evolutionarily heaving. There is not effective methods clinically to stop its development. This article aims to study the feasibility and effectiveness of Defibrase therapy on evolutionary stroke through observing curative effect of evolutionary stroke treated by defibrase therapy and analyze and compare with that of treated by routine medicine. Methods Select 52 evolutionary stroke cases 8 hours to 5 days after stroke and divide them into treatment group(28 cases):treated by 250ml saline intravenous transfusion with 10u Defibrase,once per day,after 3 successive days switch to routine treatmcnt, and control group(24 cases):receive routine treatment. Both groups have not found significant difference in age and severity through X2 inspection,and are comparable both in case history and complication accumulation.The curative effect is evaluated 10 days and 20 days after treatment respectively.Results 10 days after treatment, in treatment group total efficiency is 63%,in control group that is 36%;20 days after treatment,in treatment group total efficiency is 82% and that in control group is 53%.Both have significant difference(P<0.01).No untoward effect such as hemorrhage occurs to both groups.Discussion and Conclutions In general speaking.within 6 hours after ischmic stroke is the optimum time to conduct thrombus-dissolution,but for evolutionary stroke the situation is still developing within several hours and even several days after stroke,that is to say thrombus is still developing or ischemia half dark band is changing to irreversible .Therefore evolutionary stroke itself is the indication of needing thrombus dissolution.Volume urokinase thrombus-dissolving therapy is easy to superven serious complication such as intracrainial hemorrhage. Insertion treatment is not matured enough limited to equipment,infarct position and curative effect. Defibrase

    Introduction: Seven hundred ninety-five thousand Americans will have a stroke this year, and half will have a chronic hemiparesis. Substantial animal literature suggests that the mammalian brain has much potential to recover from acute injury using mechanisms of neuroplasticity, and that these mechanisms can be accessed using training paradigms and neurotransmitter manipulation. However, most of these findings have not been tested or confirmed in the rehabilitation setting, in large part because of the challenges in translating a conceptually straightforward laboratory experiment into a meaningful and rigorous clinical trial in humans. Through presentation of methods for a Phase II trial, we discuss these issues and describe our approach. Methods: In rodents there is compelling evidence for timing effects in rehabilitation; motor training delivered at certain times after stroke may be more effective than the same training delivered earlier or later, suggesting that there is a critical or sensitive period for strongest rehabilitation training effects. If analogous critical/sensitive periods can be identified after human stroke, then existing clinical resources can be better utilized to promote recovery. The Critical Periods after Stroke Study (CPASS) is a phase II randomized, controlled trial designed to explore whether such a sensitive period exists. We will randomize 64 persons to receive an additional 20 h of upper extremity therapy either immediately upon rehab admission, 2–3 months after stroke onset, 6 months after onset, or to an observation-only control group. The primary outcome measure will be the Action Research Arm Test (ARAT) at 1 year. Blood will be drawn at up to 3 time points for later biomarker studies. Conclusion: CPASS is an example of the translation of rodent motor recovery experiments into the clinical setting; data obtained from this single site randomized controlled trial will be used to finalize the design of a Phase III trial.

    Anders Prior

    Full Text Available BACKGROUND AND PURPOSE: It has been suggested that antipsychotic medication may be neuroprotective and may reduce post-stroke mortality, but studies are few and ambiguous. We aimed to investigate the post-stroke effects of preadmission antipsychotic use. METHODS: We conducted a nationwide, population-based cohort study of 81,143 persons admitted with stroke in Denmark from 2003-2010. Using Danish health care databases, we extracted data on preadmission use of antipsychotics and confounding factors. We examined the association between current, former, and never use of antipsychotics and stroke severity, length of hospital stay, and 30-day post-stroke mortality using logistic regression analysis, survival analysis, and propensity score matching. RESULTS: Current users of antipsychotics had a higher risk of severe or very severe stroke on The Scandinavian Stroke Scale than never users of antipsychotics (adjusted odds ratios, 1.43; 95% CI, 1.29-1.58. Current users were less likely to be discharged from hospital within 30 days of admission than never users (probability of non-discharge, 27.0% vs. 21.9%. Antipsychotics was associated with an increased 30-day post-stroke mortality among current users (adjusted mortality rate ratios, 1.42; 95% CI, 1.29-1.55, but not among former users (adjusted mortality rate ratios, 1.05; 95% CI, 0.98-1.14. CONCLUSIONS: Preadmission use of antipsychotics was associated with a higher risk of severe stroke, a longer duration of hospital stay, and a higher post-stroke mortality, even after adjustment for known confounders. Antipsychotics play an important role in the treatment of many psychiatric conditions, but our findings do not support the hypothesis that they reduce stroke severity or post-stroke mortality.

    Full Text Available Circadian variation of the onset time of acute ischemic stroke has been well studied. However, little is mentioned about the circadian variation of discharge-stroke severity and discharge-functional status. This study evaluated the impact of onset time on discharge-stroke severity and the functional status of acute ischemic stroke. Brain magnetic resonance imaging was performed on 274 acute ischemic stroke patients (66.42% male; mean age = 64.81 ± 12.80 years. All times of onset were assigned to 4-hourly periods (six groups starting from midnight. Stroke severity/functional status was evaluated on admission and discharge using the National Institute of Health Stroke Scale (NIHSS score/modified Rankin Scale (mRS and Barthel Index (BI, respectively. Using mRS, but not NIHSS score and BI, it was possible to differentiate the best and worst groups on discharge. Patients in group 2 (4 to <8 am and group 6 (8 to <12 pm had best and worst functional status, respectively. To control other stroke risk factors, multiple logistic regression analyses were conducted to examine the role of onset time in discharge mRS. Aside from age, onset time was a significant indicator in mRS, while gender, hypertension, diabetes mellitus, hyperlipidemia, atrial fibrillation, and current smoking were not. In conclusion, there is also circadian variation of discharge-functional status in patients with acute ischemic stroke when assessed by mRS.

    Meta-analyses of extant genome-wide data illustrate the need to focus on subtypes of ischemic stroke for gene discovery. The National Institute of Neurological Disorders and Stroke SiGN (Stroke Genetics Network) contributes substantially to meta-analyses that focus on specific subtypes of stroke. The National Institute of Neurological Disorders and Stroke SiGN includes ischemic stroke cases from 24 genetic research centers: 13 from the United States and 11 from Europe. Investigators harmonize ischemic stroke phenotyping using the Web-based causative classification of stroke system, with data entered by trained and certified adjudicators at participating genetic research centers. Through the Center for Inherited Diseases Research, the Network plans to genotype 10,296 carefully phenotyped stroke cases using genome-wide single nucleotide polymorphism arrays and adds to these another 4253 previously genotyped cases, for a total of 14,549 cases. To maximize power for subtype analyses, the study allocates genotyping resources almost exclusively to cases. Publicly available studies provide most of the control genotypes. Center for Inherited Diseases Research-generated genotypes and corresponding phenotypes will be shared with the scientific community through the US National Center for Biotechnology Information database of Genotypes and Phenotypes, and brain MRI studies will be centrally archived. The Stroke Genetics Network, with its emphasis on careful and standardized phenotyping of ischemic stroke and stroke subtypes, provides an unprecedented opportunity to uncover genetic determinants of ischemic stroke.

    The purpose of this study was to determine whether 74 single nucleotide polymorphisms (SNPs), which had been associated with coronary heart disease, are associated with incident ischemic stroke. Based on antecedent studies of coronary heart disease, we prespecified the risk allele for each of the 74 SNPs. We used Cox proportional hazards models that adjusted for traditional risk factors to estimate the associations of these SNPs with incident ischemic stroke during 14 years of follow-up in a population-based study of older adults: the Cardiovascular Health Study (CHS). In white CHS participants, the prespecified risk alleles of 7 of the 74 SNPs (in HPS1, ITGAE, ABCG2, MYH15, FSTL4, CALM1, and BAT2) were nominally associated with increased risk of stroke (one-sided PDMXL2, and ABCG2) were nominally associated with stroke (one-sided P<0.05, false discovery rate=0.55). The Val12Met SNP in ABCG2 was associated with stroke in both white (hazard ratio, 1.46; 90% CI, 1.05 to 2.03) and black (hazard ratio, 3.59; 90% CI, 1.11 to 11.6) participants of CHS. Kaplan-Meier estimates of the 10-year cumulative incidence of stroke were greater among Val allele homozygotes than among Met allele carriers in both white (10% versus 6%) and black (12% versus 3%) participants of CHS. The Val12Met SNP in ABCG2 (encoding a transporter of sterols and xenobiotics) was associated with incident ischemic stroke in white and black participants of CHS.

    To look for a relationship between physical fatigue and physical parameters in patients at least 3 months post stroke. We conducted a prospective cross-sectional study of 32 poststroke patients (average duration of stroke 40 months) who were recruited among in- and outpatients followed by the Department of Physical and Rehabilitation Medicine of a university hospital. Fatigue was defined as a Fatigue Severity Scale (FSS) score of 4 or more. The parameters studied were age, sex, time since stroke, Demeurisse Motor Index, Barthel Index score, new Functional Ambulation Category, Berg Balance Scale, 10-meter walk test, 6-minute walk test, Dijon Physical Activity Score, Montgomery and Asberg Depression Rating Scale, Epworth Sleepiness Scale, presence of pain, and length and area of the center of pressure displacement obtained posturographically. Two-thirds of patients (65.6%) were fatigued. The mean FSS score was 4.3 ± 1.8. Fatigue was not associated with the physical parameters studied; notably, there was no correlation with motor impairment, autonomy and walking capacity, or balance and physical activity. However, after multivariate analysis, we found an association between physical fatigue and time since the occurrence of stroke (P = .05). Our study revealed a relationship between pain and physical fatigue, as reported by 2 other studies. Poststroke fatigue management should include appropriate pain management. Further studies are necessary to determine the causes of physical fatigue after stroke.

    Full Text Available Abstract Background As low and middle-income countries such as Vietnam experience the health transition from infectious to chronic diseases, the morbidity and mortality from stroke will rise. In line with the recommendation of the Institute of Medicine’s report on “Promoting Cardiovascular Health in the Developing World” to “improve local data”, we sought to investigate patient characteristics and clinical predictors of mortality among stroke inpatients at Da Nang Hospital in Vietnam. Methods A stroke registry was developed and implemented at Da Nang Hospital utilizing the World Health Organization’s Stroke STEPS instrument for data collection. Results 754 patients were hospitalized for stroke from March 2010 through February 2011 and admitted to either the intensive care unit or cardiology ward. Mean age was 65 years, and 39% were female. Nearly 50% of strokes were hemorrhagic. At 28-day follow-up, 51.0% of patients with hemorrhagic stroke died whereas 20.3% of patients with ischemic stroke died. A number of factors were independently associated with 28-day mortality; the two strongest independent predictors were depressed level of consciousness on presentation and hemorrhagic stroke type. While virtually all patients completed a CT during the admission, evidence-based processes of care such as anti-thrombotic therapy and carotid ultrasound for ischemic stroke patients were underutilized. Conclusions This cohort study highlights the high mortality due in part to the large proportion of hemorrhagic strokes in Vietnam. Lack of hypertension awareness and standards of care exacerbated clinical outcomes. Numerous opportunities for simple, inexpensive interventions to improve outcomes or reduce recurrent stroke have been identified.

    Research on cerebral stroke symptoms using hospital records has reported that women experience more nontraditional symptoms of stroke (eg, mental status change, pain) than men do. This is an important issue because nontraditional symptoms may delay the decision to get medical assistance and increase the difficulty of correct diagnosis. In the present study, we investigate sex differences in the stroke experience as described in stories on weblogs. The goal of this study was to investigate the feasibility of using the Internet as a source of data for basic research on stroke experiences. Stroke experiences described in blogs were identified by using StoryUpgrade, a program that searches blog posts using a fictional prototype story. In this study, the prototype story was a description of a stroke experience. Retrieved stories coded by the researchers as relevant were used to update the search query and retrieve more stories using relevance feedback. Stories were coded for first- or third-person narrator, traditional and nontraditional patient symptoms, type of stroke, patient sex and age, delay before seeking medical assistance, and delay at hospital and in treatment. There were 191 relevant stroke stories of which 174 stories reported symptoms (52.3% female and 47.7% male patients). There were no sex differences for each traditional or nontraditional stroke symptom by chi-square analysis (all Ps>.05). Type of narrator, however, affected report of traditional and nontraditional symptoms. Female first-person narrators (ie, the patient) were more likely to report mental status change (56.3%, 27/48) than male first-person narrators (36.4%, 16/44), a marginally significant effect by logistic regression (P=.056), whereas reports of third-person narrators did not differ for women (27.9%, 12/43) and men (28.2%, 11/39) patients. There were more reports of at least 1 nontraditional symptom in the 92 first-person reports (44.6%, 41/92) than in the 82 third-person reports (25

  2. Rare variants in ischemic stroke: an exome pilot study.

    Directory of Open Access Journals (Sweden)

    John W Cole

    Full Text Available The genetic architecture of ischemic stroke is complex and is likely to include rare or low frequency variants with high penetrance and large effect sizes. Such variants are likely to provide important insights into disease pathogenesis compared to common variants with small effect sizes. Because a significant portion of human functional variation may derive from the protein-coding portion of genes we undertook a pilot study to identify variation across the human exome (i.e., the coding exons across the entire human genome in 10 ischemic stroke cases. Our efforts focused on evaluating the feasibility and identifying the difficulties in this type of research as it applies to ischemic stroke. The cases included 8 African-Americans and 2 Caucasians selected on the basis of similar stroke subtypes and by implementing a case selection algorithm that emphasized the genetic contribution of stroke risk. Following construction of paired-end sequencing libraries, all predicted human exons in each sample were captured and sequenced. Sequencing generated an average of 25.5 million read pairs (75 bp×2 and 3.8 Gbp per sample. After passing quality filters, screening the exomes against dbSNP demonstrated an average of 2839 novel SNPs among African-Americans and 1105 among Caucasians. In an aggregate analysis, 48 genes were identified to have at least one rare variant across all stroke cases. One gene, CSN3, identified by screening our prior GWAS results in conjunction with our exome results, was found to contain an interesting coding polymorphism as well as containing excess rare variation as compared with the other genes evaluated. In conclusion, while rare coding variants may predispose to the risk of ischemic stroke, this fact has yet to be definitively proven. Our study demonstrates the complexities of such research and highlights that while exome data can be obtained, the optimal analytical methods have yet to be determined.

    Full Text Available BACKGROUND : Acute ischemic stroke is very common cause of significant morbidity and mortality throughout the world. The causes of acute ischemic stroke could be intracranial or extra cranial. Prevention of the acute episode could be decreased by surgically treating ex tra - cranial vascular disease but the prevention of intracranial cause is only medical. Various risk factors are also associated with development of ischemic stroke. However, the association between these and the pattern of vascular involvement is not clear . AIM: The aim of the study was to 1. Identify the location of the vessel involved in different cases of ischemic stroke 2. To study the various risk factors associated with the development of ischemic stroke. MATERIALS AND METHOD S: This was a prospective study conducted between the years 2010 and 2012. All adult patients with acute ischemic stroke which was confirmed by MRI and less than two weeks duration were included in the study. Parameters recorded were presence of pre - existing comorbid conditions, n eurological examination findings, Cardiovascular system examination findings, Blood pressures, blood sugar levels and pattern of vascular involvement. This was assessed using MR angiography or four vessel Doppler. Statistical analysis was done using the SP SS software. RESULTS: Two hundred patients were enrolled in the study. Pure extracranial stenosis was present in 21.5%, extracranial with intracranial stenosis in 34%, and pure intracranial stenosis in 44.5%, which was predominant and resembled other Indi an studies. 15.5% of patients had significant carotid stenosis based on Doppler study and were suitable candidates for carotid endarterectomy. Middle cerebral artery was commonly involved (55%. Hypertension (63.5%, diabetes mellitus (48%, alcoholism (20 .5% and smoking (18.5% were the common risk factors. Prevalence of these risk factors was more in those with intracranial stenosis in our study, elevated total

    Gross-motor impairments are common after stroke, but efficacious and motivating therapies for these impairments are scarce. We present a novel musical sonification therapy especially designed to retrain gross-motor functions. Four stroke patients were included in a clinical pre-post feasibility study and were trained with our sonification training. Patients' upper-extremity functions and their psychological states were assessed before and after training. The four patients were subdivided into two groups, with both groups receiving 9 days of musical sonification therapy (music group, MG) or a sham sonification training (control group, CG). The only difference between these training protocols was that, in the CG, no sound was played back. During the training the patients initially explored the acoustic effects of their arm movements, and at the end of the training the patients played simple melodies by moving their arms. The two patients in the MG improved in nearly all motor function tests after the training. They also reported in the stroke impact scale, which assesses well-being, memory, thinking, and social participation, to be less impaired by the stroke. The two patients in the CG did benefit less from the movement training. Taken together, musical sonification may be a promising therapy for impairments after stroke.

    Full Text Available Cerebrovascular diseases are among the top three causes of death in Cuba and the world, about 80 % of these patients belong to Ischemic Stroke. The objective of this paper is to describe the clinical and developmental profile of patients who died of Ischemic Stroke. A descriptive, prospective research, cross- sectional study was made, the sample included all deaths from ischemic stroke at the University Hospital "Camilo Cienfuegos" Sancti Spiritus, between January 1st, 2001 and December 31, 2010, and persons over 60 years of age with necropsy performed. Atherothrombotic stroke was the most frequent category, the highest mortality rates were observed in persons over 80 years of age and in females, hypertension, ischemic heart disease and transient ischemic attack were the main significant medical history; most patients were admitted in the stroke unit and died in Middle Progressive Care, cerebral edema and intracranial hypertension and hypostatic bronchopne umonia were complications and specific main causes of most frequent death. Value of cerebral edema and hypostatic bronchopneumonia as clinical complications and causes of death in patients investigated is confirmed.

    Full Text Available AIM: Physical activity (PA confers some protection against development of heart failure (HF but little is known of the role of intensity and duration of exercise. METHODS AND RESULTS: In a prospective cohort study of men and women free of previous MI, stroke or HF with one or more examinations in 1976-2003, we studied the association between updated self-assessed leisure-time PA, speed and duration of walking and subsequent hospitalization or death from HF. Light and moderate/high level of leisure-time PA and brisk walking were associated with reduced risk of HF in both genders whereas no consistent association with duration of walking was seen. In 18,209 subjects age 20-80 with 1580 cases of HF, using the lowest activity level as reference, the confounder-adjusted hazard ratios (HR for light and moderate/high leisure-time physical activity were 0.75 (0.66-0.86 and 0.80 (0.69-0.93, respectively. In 9,937 subjects with information on walking available and 542 cases of HF, moderate and high walking speed were associated with adjusted HRs of 0.53 (0.43-0.66 and 0.30 (0.21-0.44, respectively, and daily walking of ½-1 hrs, 1-2 and >2 hrs with HR of 0.80 (0.61-1.06, 0.82 (0.62-1.06, and 0.96 (0.73-1.27, respectively. Results were similar for both genders and remained robust after exclusion of HF related to coronary heart disease and after a series of sensitivity analyses. CONCLUSIONS: Speed rather than duration of walking was associated with reduced risk of HF. Walking is the most wide-spread PA and public health measures to curb the increase in HF may benefit from this information.

    Full Text Available Abstract Background Stroke remains a leading cause of disability worldwide and results in muscle performance deficits and limitations in activity performance. Rehabilitation aims to address muscle dysfunction in an effort to improve activity and participation. While muscle strength has an impact on activity performance, muscle power has recently been acknowledged as contributing significantly to activity performance in this population. Therefore, rehabilitation efforts should include training of muscle power. However, little is known about what training parameters, or load, optimize muscle power performance in people with stroke. The purpose of this study was to investigate lower limb muscle power performance at differing loads in people with and without stroke. Methods A cross-sectional study design investigated muscle power performance in 58 hemiplegic and age matched control participants. Lower limb muscle power was measured using a modified leg press machine at 30, 50 and 70% of one repetition maximum (1-RM strength. Results There were significant differences in peak power between involved and uninvolved limbs of stroke participants and between uninvolved and control limbs. Peak power was greatest when pushing against a load of 30% of 1RM for involved, uninvolved and control limbs. Involved limb peak power irrespective of load (Mean:220 ± SD:134 W was significantly lower (p  Conclusions Significant power deficits were seen in both the involved and uninvolved limbs after stroke. Maximal muscle power was produced when pushing against lighter loads. Further intervention studies are needed to determine whether training of both limbs at lighter loads (and higher velocities are preferable to improve both power and activity performance after stroke.

    The neural mechanisms that support aphasia recovery are not yet fully understood. It has been argued that the functional reorganization of language networks after left-hemisphere stroke may engage perilesional left brain areas as well as homologous right-hemisphere regions. In this chapter, we...... that language recovery after stroke may integrate left- as well as right-hemisphere brain regions to a different degree over the time course of recovery. Although the results of these preliminary studies provide some evidence that noninvasive brain stimulation may promote aphasia recovery, the reported effect...... summarize how noninvasive brain stimulation can be used to elucidate mechanisms of plasticity in language networks and enhance language recovery after stroke. We first outline some basic principles of transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS). We then present...

    Patent foramen ovale is associated with ischemic stroke in patients without a clearly identifiable etiology for stroke (cryptogenic stroke). Paradoxical embolization is thought to be a potential mechanism. However, patent foramen ovale is also found in patients with known cause of stroke. Therefore, using contrast transesophageal echocardiography, we characterized the patent foramen ovale in cryptogenic stroke patients to assess morphological factors that may contribute to paradoxical embolization. Methods: Contrast transesophageal echocardiographic studies of 74 consecutive patients referred for ischemic stroke were reviewed. Twenty-three patients with patent foramen ovale were identified. These patients were classified as having strokes of determined origin or cryptogenic strokes according to criteria developed for the Stroke Data Bank of the National Institute of Neurological Disorders and Stroke. Separation of septum primum from secundum and the number of microbubbles appearing in left atrium were then quantitated. These parameters were compared between patients with cryptogenic stroke and those with known cause of stroke. Results: The patent foramen ovale dimension was significantly larger in patients with cryptogenic stroke compared with patients with an identifiable cause of stroke (2.1+/-1.7 mm versus 057+/-0.78 mm [mean+/-SD]; Ppatent foramen ovale with more extensive right-to-left inter-atrial shunting than patients with stroke of determined cause. Transesophageal echocardiographically identifiable characteristics of patent foramen ovale may be important in defining the clinical significance of individual patent foramina.

    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

    Full Text Available Background: Stroke is a leading cause of disability in adults. Following stroke, 60% of people report needing help with everyday activities, and 80% report having very few meaningful activities. These restrictions often continue for years. This study explored the efficacy of Occupational Performance Coaching for stroke survivors (OPC-Stroke on the participation level of adults in the later stage of stroke rehabilitation. Method: A descriptive case study design was used. One participant in the later stages of rehabilitation was recruited. Outcome measures for participation, goal performance and satisfaction, and emotional well-being were administered pre and postintervention to observe for direction of change. A semi-structured interview was carried out postintervention to explore the participant’s experiences of the intervention. Results: The participant who took part in the study reported improvement with his goal performance and satisfaction. However, the level of participation did not improve and emotional well-being decreased. Qualitative data revealed an appreciation of the intervention and a recommendation of the intervention for others. Conclusion: OPC-Stroke was valued by the participant and shows promise for improving goal performance and satisfaction. Further research is necessary to determine the potential efficacy of OPC-Stroke in later stages of rehabilitation.

    Stroke symptoms can be very stressful for family caregivers, but most knowledge about the prevalence and stressfulness of stroke-related patient problems is derived from convenience samples. In addition, little is known about perceived benefits of the stroke caregiving experience. The purpose of this study was to determine the prevalence and stressfulness of stroke-related problems, and perceived benefits of caregiving, as reported by an epidemiologically derived sample of caregivers of stroke survivors. Stroke survivors (N=75) from a prospective epidemiological study of stroke, the REasons for Geographic and Racial Differences in Stroke (REGARDS) study, and their family caregivers were followed. Caregivers were given a comprehensive telephone interview 8 to 12 months after the stroke, using measures of stroke patient problems, caregiver appraisals of the stressfulness of these problems, and perceived benefits of caregiving. Caregivers rated patient problems with mood (depression, loneliness and anxiety), memory, and physical care (bowel control), as the most stressful, but reported prevalence of these problems was lower than those reported previously in studies using clinical samples. Caregivers also reported many benefits from caregiving, with over 90% reporting that caregiving enabled them to appreciate life more. Epidemiologically based studies of stroke caregiving provide a unique picture of caregiver strains and benefits compared with clinical studies, which tend to over-represent more impaired patients. Support for caregivers should include interventions to aid their coping with highly stressful mood, physical care, and cognitive problems of stroke patients, but should also attend to perceived benefits of caregiving.

    Elderly stroke survivors are at risk of malnutrition and long-term cognitive impairment. Vitamin B-related metabolites, folate and methylmalonic acid, have been implicated in cognitive function. We conducted a study exploring the relationship between blood folate, methylmalonic acid and post-stroke cognitive impairment. This is a cross sectional study of elderly Swedish patients (n=149) 20 months post-stroke, assessed using the Mini Mental State Examination, serum blood levels of methylmalonic acid and red blood cell levels of folate. Linear modeling indicated that low levels of blood folate and elevated methylmalonic acid significantly contributed to cognitive impairment in stroke survivors. Half of the stroke survivors were shown to have folate deficiency at 20 months after stroke. Folate deficiency is common long term after stroke and both low folate and elevated methylmalonic acid appear to be associated with long term cognitive impairment, in elderly Swedish stroke survivors.

    Stroke is a life-threatening or life-changing disease that is expensive in health care costs and lost productivity. Stroke also is a leading cause of human suffering. While the risk of stroke may be reduced with advances in prevention, recent advances in acute care can limit the consequences of stroke. In particular, the success of reperfusion therapies including intra-arterial interventions and intravenous administration of thrombolytic agents means that some patients with stroke may be cured. Still, the time window for effective treatment of stroke is relatively short. As a result, modern stroke management requires the close collaboration of the public, health care providers, administrators, insurance companies, and the government. Potential strategies to extend modern stroke care to as many patients as possible include 1) educational programs to train community emergency medical service personnel and physicians, 2) development of stroke care plans at community hospitals, 3) an integrated community-comprehensive stroke center program based on consultation, and telemedicine. The goal is to have a highly integrated approach to provide emergency treatment of the stroke that provides key emergency treatment, including intravenous administration of thrombolytic medications, at a community hospital (primary stroke center) with evacuation to a comprehensive stroke center that has resources and expertise that are not available in the primary stroke center. Taiwan is an ideal location for the development of such regional stroke programs.

    Full Text Available Abstract Background Effective stroke intervention and risk reduction depend on the general public's awareness and knowledge of stroke. In Korea, where both traditional Oriental medicine and Western medicine are practiced, estimates of the general public's awareness and knowledge of stroke are poor. The present study sought to describe the inception cohort of the Ansan Geriatric Study (AGE study and to determine baseline stroke awareness and preferred medical treatment for stroke in this Korean sample. Methods A total of 2,767 subjects selected randomly from the Ansan Geriatric Study in South Korea were questioned about stroke. Their answers were compared with their sociodemographic data and other variables. Results Only 44.8% of participants correctly identified stroke as a vascular disease in the human brain. Sudden numbness or weakness was the most frequently identified stroke warning sign (60.2%. Hypertension (66.7% and mental stress (62.2% were most frequently identified as stroke risk factors. The contributions of diabetes mellitus and cardiovascular disease to stroke were underestimated; they were identified as risk factors by 28.3% and 18.6% of participants, respectively. The predictors for poor knowledge of stroke warning signs and risk factors were similar irrespective of preference for Western or Oriental medical treatment, and included those with lower levels of education and inaccurate definition of stroke. Television and radio (40.3% were the most frequent sources of stroke information for both groups. Conclusion This study shows that knowledge of stroke is similar among Koreans with preferences for either Western or Oriental medical treatment and that misunderstandings about stroke are common among the Korean elderly. In order to prevent and manage stroke effectively, public health education regarding basic concepts of stroke is necessary. This should target those with a lower level of education and a misunderstanding of the

    Full Text Available Background: Few studies have assessed the associations between sleep duration and stroke subtypes. We examined whether sleep duration is associated with mortality from total stroke, ischemic stroke, and hemorrhagic stroke in a population-based cohort of Japanese men and women. Methods: Subjects included 12 875 men and 15 021 women aged 35 years or older in 1992, who were followed until 2008. The outcome variable was stroke death (ischemic stroke, hemorrhagic stroke, and total stroke. Results: During follow-up, 611 stroke deaths (354 from ischemic stroke, 217 from hemorrhagic stroke, and 40 from undetermined stroke were identified. Compared with 7 h of sleep, ≥9 h of sleep was significantly associated with an increased risk of total stroke and ischemic stroke mortality after controlling for covariates. Hazard ratios (HRs and 95% confidence intervals (CIs were 1.51 (95% CI, 1.16–1.97 and 1.65 (95% CI, 1.16–2.35 for total stroke mortality and ischemic stroke mortality, respectively. Short sleep duration (≤6 h of sleep was associated with a decreased risk of mortality from total stroke (HR 0.77; 95% CI, 0.59–1.01, although this association was of borderline significance (P = 0.06. The trends for total stroke and ischemic stroke mortality were also significant (P < 0.0001 and P = 0.0002, respectively. There was a significant risk reduction of hemorrhagic stroke mortality for ≤6 h of sleep as compared with 7 h of sleep (HR 0.64; 95% CI, 0.42–0.98; P for trend = 0.08. The risk reduction was pronounced for men (HR 0.31; 95% CI, 0.16–0.64. Conclusions: Data suggest that longer sleep duration is associated with increased mortality from total and ischemic stroke. Short sleep duration may be associated with a decreased risk of mortality from hemorrhagic stroke in men.

    2009-10-01

    Full Text Available Abstract Background A growing body of evidence suggests that psychological stress contributes to coronary artery disease. However, associations between stress and stroke are less clear. In this study, we investigated the possible association between ischemic stroke and self-perceived psychological stress, as measured by a single-item questionnaire, previously reported to be associated with myocardial infarction. Methods In the Sahlgrenska Academy Study on Ischemic Stroke (SAHLSIS, 600 consecutive patients with acute ischemic stroke (aged 18 to 69 years and 600 age-matched and sex-matched population controls were recruited. Ischemic stroke subtype was determined according to Trial of Org 10172 in Acute Stroke Treatment (TOAST criteria. Self-perceived psychological stress preceding stroke was assessed retrospectively using a single-item questionnaire. Results Permanent self-perceived psychological stress during the last year or longer was independently associated with overall ischemic stroke (multivariate adjusted odds ratio (OR 3.49, 95% confidence interval (CI 2.06 to 5.93. Analyses by stroke subtype showed that this association was present for large vessel disease (OR 3.91, 95% CI 1.58 to 9.67, small vessel disease (OR 3.20, 95% CI 1.64 to 6.24, and cryptogenic stroke (OR 4.03, 95% CI 2.34 to 6.95, but not for cardioembolic stroke (OR 1.48, 95% CI 0.64 to 3.39. Conclusion In this case-control study, we found an independent association between self-perceived psychological stress and ischemic stroke. A novel finding was that this association differed by ischemic stroke subtype. Our results emphasize the need for further prospective studies addressing the potential role for psychological stress as a risk factor for ischemic stroke. In such studies ischemic stroke subtypes should be taken into consideration.

    Current guidelines on stroke prevention have recommendations on desirable cholesterol levels, but not on nonfasting triglycerides. We compared stepwise increasing levels of nonfasting triglycerides and cholesterol for their association with risk of ischemic stroke in the general population. A total of 7,579 women and 6,372 men from the Copenhagen City Heart Study with measurements of nonfasting triglycerides and cholesterol at baseline in 1976-1978 were followed for up to 33 years; of these, 837 women and 837 men developed ischemic stroke during follow-up, which was 100% complete. The fluctuation of nonfasting triglycerides and cholesterol over 15 years was similar. In both women and men, stepwise increasing levels of nonfasting triglycerides were associated with increased risk of ischemic stroke. Compared to women with triglycerides triglyceride levels of 1.00-1.99 mmol/liter to 3.9 (95%CI, 1.3-11.1) for triglyceride levels ≥ 5 mmol/liter (trend: p cholesterol levels were not associated with risk of ischemic stroke except in men with cholesterol levels ≥ 9.00 mmol/liter vs triglycerides were associated with increasing risk of ischemic stroke while increasing cholesterol levels were not. In men, these results were similar except that cholesterol ≥ 9.00 mmol/liter was associated with increased risk of ischemic stroke. Copyright © 2011 American Neurological Association.

  16. Rationale and design of INTERSTROKE: a global case-control study of risk factors for stroke

    2010-01-01

    Stroke is a major global health problem. It is the third leading cause of death and the leading cause of adult disability. INTERHEART, a global case-control study of acute myocardial infarction in 52 countries (29,972 participants), identified nine modifiable risk factors that accounted for >90......% of population-attributable risk. However, traditional risk factors (e.g. hypertension, cholesterol) appear to exert contrasting risks for stroke compared with coronary heart disease, and the etiology of stroke is far more heterogeneous. In addition, our knowledge of risk factors for stroke in low......-income countries is inadequate, where a very large burden of stroke occurs. Accordingly, a similar epidemiological study is required for stroke, to inform effective population-based strategies to reduce the risk of stroke. Methods: INTERSTROKE is an international, multicenter case-control study. Cases are patients...

    Based on prospective data from the Framingham study relating systolic pressure, diastolic pressure, age, and pulse-wave configuration to future stroke incidence, it would appear that isolated systolic hypertension predisposes to stroke independent of arterial rigidity. The prevalence of isolated systolic hypertension increased with age and with the degree of blunting of the dicrotic notch in the pulse wave. Subjects with isolated systolic hypertension experienced two to four times as many strokes as did normotensive persons. While diastolic pressure is related to stroke incidence, in the subject with systolic hypertension, the diastolic component adds little to risk assessment and in men, in this subgroup, appears unrelated to stroke incidence.

    To investigate the association among migraine, ischemic stroke, and stroke subtypes in the Atherosclerosis Risk in Communities (ARIC) study. In this ongoing, prospective, longitudinal community-based cohort study, participants were given an interview ascertaining migraine history in 1993-1995, and were followed for all vascular events, including stroke. All stroke events over the subsequent 20 years were adjudicated and classified into stroke subtypes by standard definitions. Cox proportional hazards models adjusted for stroke risk factors were used to study the relationship between migraine and ischemic stroke, overall, as well as stroke subtypes (cardioembolic, lacunar, or thrombotic). We identified 1,622 migraineurs among 12,758 participants. Mean age of the study population at the 3rd clinical visit was 59 years. When compared to nonheadache participants, there was a significant association between migraine with visual aura and ischemic stroke (hazard ratio [HR] 1.7, 95% confidence interval [CI] 1.2-2.6, p = 0.008). Migraine without visual aura was not significantly associated with ischemic stroke (HR 1.2, CI 1.0-1.8, p = 0.28) when compared to nonheadache participants. Among the 3 subtypes of ischemic stroke evaluated, migraine with visual aura was significantly associated only with cardioembolic stroke (HR 3.7, 95% CI 1.6-8.7, p = 0.003). In participants with migraine with visual aura in late middle age, increased risk of cardioembolic stroke was observed. Migraine with visual aura was linked to increased stroke risk, while migraine without visual aura was not, over the period of 20 years. These results are specific to older migraineurs. © 2016 American Academy of Neurology.

    The disparities in stroke mortality between blacks and whites, as well as the increased stroke mortality in the "stroke belt" have long been noted. The reasons for these disparities have yet to be fully explained. The association between trace element status and cardiovascular diseases, including stroke, has been suggested as a possible contributor to the disparities in stroke mortality but has not been fully explored. The purpose of this study is to investigate distributions of four trace elements (arsenic, mercury, magnesium, and selenium) in the environment in relation to stroke risk. The study population (N=27,770) is drawn from the Reasons for Geographic and Racial Disparities in Stroke (REGARDS) cohort. Environmental distribution of each trace element was determined using data from the United States Geological Survey (USGS) and was categorized in quartiles. A proportional hazards model, adjusted for demographic data and stroke risk factors, was used to examine the association of interest. The results showed that higher selenium levels in the environment were associated with increased stroke risk, and the hazard ratio for the 4th quartile compared to the 1st quartile was 1.33 (95% CI: 1.09, 1.62). However, there was no statistically significant relationship between environmental arsenic, mercury or magnesium and the risk of stroke. Because of dietary and non-dietary exposure as well as bioavailability, further research using biomarkers is warranted to examine the association between these trace elements and the risk of stroke.

    Between 1967 and 1977, 395 consecutive cases of glomerulonephritis (GN) were collected by a Copenhagen study group. The diagnosis was established by histological and biochemical criteria. Light microscopy investigations of thin silver-stained sections were applied. In a follow-up in 1980 all cases were categorized by one of the following end points: death without uremia, uremia, recovery, or censored cases. The course is presented in figures showing the cumulated distribution of outcomes in relation to observation time. Each histological subgroup of GN had its own characteristic course with respect to initial rates of changes in the renal state, as well as to frequency of recovery, uremia and death. The prognosis was good in minimal changes GN and proliferative GN, bad in unclassified GN and worst in extracapillary GN. When part of a connective tissue disease, GN carried a poor prognosis. We conclude that histological classification of GN based on light microscopy offers a reliable means of predicting the long-term prognosis.

    Objective: Despite epidemiologic data showing an increased stroke incidence in African ancestry populations, genetic studies in this group have so far been limited, and there has been little characterization of the genetic contribution to stroke liability in this population, particularly for stroke subtypes. Methods: We evaluated the evidence that genetic factors contribute to stroke and stroke subtypes in a population of 917 African and African Caribbean stroke cases and 868 matched controls from London, United Kingdom. We (1) estimated the heritability of stroke in this population using genomic-relatedness matrix-restricted maximum likelihood approaches, (2) assessed loci associated with stroke in Europeans in our population, and (3) evaluated the influence of genetic factors underlying cardiovascular risk factors on stroke using polygenic risk scoring. Results: Our results indicate a substantial genetic contribution to stroke risk in African ancestry populations (h2 = 0.35 [SE = 0.19], p = 0.043). Polygenic risk scores indicate that cardiovascular risk scores contribute to the genetic liability (odds ratio [OR] 1.09 [95% confidence interval (CI) 1.01–1.17], p = 0.029) and point to a strong influence of type 2 diabetes in large vessel stroke (OR 1.62 [95% CI 1.19–2.22], p = 0.0024). Single nucleotide polymorphisms associated with ischemic stroke in Europeans shared direction of effect in SLESS (p = 0.031), suggesting that disease mechanisms are shared across ancestries. Conclusions: Stroke in African ancestry populations is highly heritable and influenced by genetic determinants underlying cardiovascular risk factors. In addition, stroke loci identified in Europeans share direction of effect in African populations. Future genome-wide association studies must focus on incorporating African ancestry individuals.

    Swallowing dysfunction is common and disabling after acute stroke; however, the mechanism of dysphagia or recovery of swallowing from dysphagia remains uncertain. The purpose of this study was to explore cerebral activation of swallowing in dysphagia using functional MRI (fMRI) to compare the functional anatomy of swallowing in unilateral hemispheric stroke patients and healthy adults. In total, five left hemispheric stroke patients with dysphagia, five right hemispheric stroke patients with dysphagia and 10 healthy controls were examined with event related fMRI while laryngeal swallow related movements were recorded. Data were processed using the general linear model. A multifocal cerebral representation of swallowing was identified predominantly in the left hemisphere, in a bilateral and asymmetrical manner. Cerebral activation during swallowing tasks was localised to the precentral, postcentral and anterior cingulate gyri, insula and thalamus in all groups. Activation of volitional swallowing in dysphagic unilateral hemispheric stroke patients might require reorganisation of the dominant hemispheric motor cortex, or a compensatory shift in activation to unaffected areas of the hemisphere. The results indicate that unilateral stroke of either cerebral hemisphere can produce dysphagia. Effective recovery is associated with cerebral activation related to cortical swallowing representation in the compensating or recruited areas of the intact hemisphere. Functional MRI is a useful method for exploring the spatial localisation of changes in neuronal activity during tasks that may be related to recovery. Therefore, the subsequent information gleaned from changes in neural plasticity could be useful for assessing the prognosis of dysphagic stroke.

    Full Text Available BACKGROUND: Whereas brain-derived neurotrophic factor (BDNF levels are measured in the brain in animal models of stroke, neurotrophin levels in stroke patients are measured in plasma or serum samples. The present study was designed to investigate the meaning of circulating BDNF levels in stroke patients. METHODS AND RESULTS: Unilateral ischemic stroke was induced in rats by the injection of various numbers of microspheres into the carotid circulation in order to mimic the different degrees of stroke severity observed in stroke patients. Blood was serially collected from the jugular vein before and after (4 h, 24 h and 8 d embolization and the whole brains were collected at 4, 24 h and 8 d post-embolization. Rats were then selected from their degree of embolization, so that the distribution of stroke severity in the rats at the different time points was large but similar. Using ELISA tests, BDNF levels were measured in plasma, serum and brain of selected rats. Whereas plasma and serum BDNF levels were not changed by stroke, stroke induced an increase in brain BDNF levels at 4 h and 24 h post-embolization, which was not correlated with stroke severity. Individual plasma BDNF levels did not correlate with brain levels at any time point after stroke but a positive correlation (r = 0.67 was observed between individual plasma BDNF levels and stroke severity at 4 h post-embolization. CONCLUSION: Circulating BDNF levels do not mirror brain BDNF levels after stroke, and severe stroke is associated with high plasma BDNF in the very acute stage.

    2008-08-01

    Full Text Available Abstract Background Although cigarette smoking is a well-established risk factor for vascular disease, the genetic mechanisms that link cigarette smoking to an increased incidence of stroke are not well understood. Genetic variations within the genes of the inflammatory pathways are thought to partially mediate this risk. Here we evaluate the association of several inflammatory gene single nucleotide polymorphisms (SNPs with ischemic stroke risk among young women, further stratified by current cigarette smoking status. 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-comparable control subjects (43.1% African-American. Several inflammatory candidate gene SNPs chosen through literature review were genotyped in the study population and assessed for association with stroke and interaction with smoking status. Results Of the 8 SNPs (across 6 genes analyzed, only IL6 SNP rs2069832 (allele C, African-American frequency = 92%, Caucasian frequency = 55% was found to be significantly associated with stroke using an additive model, and this was only among African-Americans (age-adjusted: OR = 2.2, 95% CI = 1.0–5.0, p = 0.049; risk factor adjusted: OR = 2.5, 95% CI = 1.0–6.5, p = 0.05. When stratified by smoking status, two SNPs demonstrated statistically significant gene-environment interactions. First, the T allele (frequency = 5% of IL6 SNP rs2069830 was found to be protective among non-smokers (OR = 0.30, 95% CI = 0.11–.082, p = 0.02, but not among smokers (OR = 1.63, 95% CI = 0.48–5.58, p = 0.43; genotype by smoking interaction (p = 0.036. Second, the C allele (frequency = 39% of CD14 SNP rs2569190 was found to increase risk among smokers (OR = 2.05, 95% CI = 1.09–3.86, p = 0.03, but not among non-smokers (OR = 0.93, 95% CI = 0.62–1.39, p = 0.72; genotype by smoking interaction (p = 0.039.

    Popper conceived an experiment whose analysis led to a result that he deemed absurd. Popper wrote that his reasoning was based on the Copenhagen interpretation and therefore invalidated the latter. Actually, Popper's argument involves counterfactual reasoning and violates Bohr's complementarity principle. The absurdity of Popper's result only confirms Bohr's approach.

    Rationale The effectiveness of clinician-focused interventions to improve stroke care is uncertain. Aims To determine whether an organizational intervention can improve the quality of stroke care over usual care. Sample size estimates To detect an absolute 10% difference in overall performance (composite outcome), a minimum of 21 hospitals and 843 patients per group was determined. Methods and design Before and after controlled design in hospitals in Queensland, Australia. Intervention Externally facilitated program (StrokeLink) using outreach workshops incorporating clinical performance feedback, patient outcomes (survival, quality of life at 90-180 days), local barrier assessments to best practice care, action planning, and ongoing support. Descriptive and multivariable analyses adjusted for patient correlations by hospital (intention-to-treat method). Context Concurrent implementation of financial incentives to increase stroke unit access and use of the Australian Stroke Clinical Registry for performance monitoring. Study outcome(s) Primary outcome: net change in composite score (i.e. total number of process indicators achieved divided by the sum of eligible indicators for each cohort). change in individual indicators, change in composite score comparing hospitals that did or did not develop action plans (per-protocol analysis), impact on 90-180-day health outcomes. Sensitivity analyses: hospital self-rated status, alternate cross-sectional audit data (Stroke Foundation). To account for temporal effects, comparison of Queensland hospital performance relative to other Australian hospitals will also be undertaken. Discussion Twenty-one hospitals were recruited; however, one was unable to participate within the study time frame. Workshops were held between 11 March 2014 and 7 November 2014. Data are ready for analysis.

    Full Text Available Abstract Background The exact etiology of ischemic stroke remains unclear, because multiple genetic predispositions and environmental risk factors may be involved, and their interactions dictate the complexity. Family-based studies provide unique features in design, while they are currently underrepresented for studies of ischemic stroke in developing countries. The Fangshan/Family-based Ischemic Stroke Study In China (FISSIC program aims to conduct a genetic pedigree study of ischemic stroke in rural communities of China. Methods/Design The pedigrees of ischemic stroke with clear documentation are recruited by using the proband-initiated contact method, based on the stroke registry in hospital and communities. Blood samples and detailed information of pedigrees are collected through the health care network in the rural area, and prospective follow-up of the pedigrees cohort is scheduled. Complementary strategies of both family-based design and matched case-spousal control design are used, and comprehensive statistical methods will be implemented to ascertain potential complex genetic and environmental factors and their interactions as well. Discussion This study is complementary to other genetic pedigree studies of ischemic stroke, such as the Siblings With Ischemic Stroke Study (SWISS, which are established in developed countries. We describe the protocol of this family-based genetic epidemiological study that may be used as a new practical guideline and research paradigm in developing countries and facilitate initiatives of stroke study for international collaborations.

    No economic data from population-based studies exist on acute or late hospital, community, and indirect costs of stroke associated with atrial fibrillation (AF-stroke). Such data are essential for policy development, service planning, and cost-effectiveness analysis of new therapeutic agents. In a population-based prospective study of incident and recurrent stroke treated in hospital and community settings, we investigated direct (healthcare related) and indirect costs for a 2-year period. Survival, disability, poststroke residence, and healthcare use were determined at 90 days, 1 year, and 2 years. Acute hospital cost was determined using a case-mix approach, and other costs using a bottom-up approach (2007 prices). In 568 patients ascertained in 1 year (2006), the total estimated 2-year cost was $33.84 million. In the overall sample, AF-stroke accounted for 31% (177) of patients, but a higher proportion of costs (40.5% of total and 45% of nursing home costs). On a per-patient basis compared with non-AF-stroke, AF-stroke was associated with higher total (P<0.001) and acute hospital costs (P<0.001), and greater nursing home (P=0.001) and general practitioner (P<0.001) costs among 90-day survivors. After stratification by stroke severity in survivors, AF was associated with 2-fold increase in costs in patients with mild-moderate (National Institutes of Health Stroke Scale, 0-15) stroke (P<0.001) but not in severe stroke (National Institutes of Health Stroke Scale ≥16; P=0.7). In our population study, AF-stroke was associated with substantially higher total, acute hospital, nursing home, and general practitioner costs per patient. Targeted programs to identify AF and prevent AF-stroke may have significant economic benefits, in addition to health benefits. © 2014 American Heart Association, Inc.

    Full Text Available Objective: To investigate life satisfaction in spouses of middle-aged stroke survivors from the long-term perspective and to identify factors that explain their life satisfaction. Design: Cross-sectional, case-control study. Subjects: Cohabitant spouses of survivors of ischaemic stroke aged < 70 years at stroke onset (n = 248 and spouses of controls (n = 246. Methods: Assessments were made 7 years after inclusion to the study. Spouses’ life satisfaction was assessed with the Fugl-Meyer’s Life Satisfaction Check-List (LiSAT 11. Stroke-related factors were examined with the National Institutes of Health stroke scale, Mini-Mental State Examination, Barthel Index and modified Rankin Scale. Results: Spouses of stroke survivors had significantly lower satisfaction with general life, leisure, sexual life, partner relationship, family life, and poorer somatic and psychological health than spouses of controls. Caregiving spouses had significantly lower scores on all life domains except vocation and own activities of daily living than non-caregiving spouses. Spouses’ satisfaction on different life domains was explained mainly by their age, sex, support given to the partner, and the survivor’s level of global disability, to which both physical and cognitive impairments contributed. Conclusion: Seven years after stroke, spouses of stroke survivors reported lower life satisfaction compared with spouses of controls. Life satisfaction in stroke survivors’ spouses was associated with spouses’ age, sex, giving support, and the stroke survivors’ level of global disability.

    Full Text Available BACKGROUND: Stroke is a growing public health concern in low- and middle- income countries. Improved knowledge about the association between socioeconomic status and stroke in these countries would enable the development of effective stroke prevention and management strategies. This study presents the association between socioeconomic status and the prevalence of stroke in Morocco, a lower middle-income country. METHODS: Data on the prevalence of stroke and stroke-related risk factors were collected during a large population-based survey. The diagnosis of stroke in surviving patients was confirmed by neurologists while health, demographic, and socioeconomic characteristics of households were collected using structured questionnaires. We used Multiple Correspondence Analysis to develop a wealth index based on characteristics of the household dwelling as well as ownership of selected assets. We used logistic regressions controlling for multiple variables to assess the statistical association between socioeconomic status and stroke. FINDINGS: Our results showed a significant association between household socioeconomic status and the prevalence of stroke. This relationship was non-linear, with individuals from both the poorest (mainly rural and richest (mainly urban households having a lower prevalence of stroke as compared to individuals with medium wealth level. The latter belonged mainly to urban households with a lower socioeconomic status. When taking into account the urban population only, we observed that a third of poorest households experienced a significantly higher prevalence of stroke compared to the richest third (OR = 2.06; CI 95%: 1.09; 3.89. CONCLUSION: We conclude that individuals from the most deprived urban households bear a higher risk of stroke than the rest of the population in Morocco. This result can be explained to a certain extent by the higher presence of behavioral risk factors in this specific category of the population

    Full Text Available In France, the prevalence of stroke and the level of disability of stroke survivors are little known. The aim of this study was to evaluate functional limitations in adults at home and in institutions, with and without self-reported stroke. A survey named "the Disability Health survey" was carried out in people's homes (DHH and in institutions (DHI. Medical history and functional level (activities-of-daily-living, ADL and instrumented-activities-of-daily-living IADL were collected through interviews. The modified Rankin score (mRS and the level of dependence and disability were compared between participants with and without stroke. 33896 subjects responded. The overall prevalence of stroke was 1.6% (CI95% [1.4%-1.7%]. The mRS was over 2 for 34.4% of participants with stroke (28.7% of participants at home and 87.8% of participants in institutions versus respectively 3.9%, 3.1% and 71.6% without stroke. Difficulty washing was the most frequently reported ADL for those with stroke (30.6% versus 3% for those without stroke. Difficulty with ADL and IADL increased with age but the relative risk was higher below the age of 60 (17 to 25 than over 85 years (1.5 to 2.2, depending on the ADL. In the overall population, 22.6% of those confined to bed or chair reported a history of stroke. These results thus demonstrate a high national prevalence of stroke. Older people are highly dependent, irrespective of stroke history and the relative risk of dependence in young subjects with a history of stroke is high compared with those without.

    2015-08-01

    Informal caregivers are vital to the long-term care and rehabilitation of stroke survivors worldwide. However, caregiving has been associated with negative psychological outcomes such as anxiety and depression, which leads to concerns about caregiver as well as stroke survivor well-being. Furthermore, caregivers may not receive the support and service provision they require from the hospitals and community. This study examines caregiver psychological well-being and satisfaction with service provision in the context of stroke. Caregiver data were collected as part of the ASPIRE-S study, a prospective study of secondary prevention and rehabilitation which assessed stroke patients and their carers at six-months post stroke. Carer assessment included measurement of demographics, satisfaction with care (UK Healthcare Commission National Patient Survey of Stroke Care), psychological distress (Hospital Anxiety and Depression Scale), and vulnerability (Vulnerable Elders Scale). Logistic regression analyses and chi-squared tests were performed using stata version 12. Analyses from 162 carers showed substantial levels of dissatisfaction (37·9%) with community and hospital services, as well as notable levels of anxiety (31·3%) and depressive symptoms (18·8%) among caregivers. Caregiver anxiety was predicted by stroke survivor anxiety (OR = 3·47, 95% CI 1·35-8·93), depression (OR = 5·17, 95% CI 1·83-14·58), and stroke survivor cognitive impairment (OR 2·35, 95% CI 1·00-5·31). Caregiver depression was predicted by stroke survivor anxiety (OR = 4·41, 95% CI 1·53-12·72) and stroke survivor depression (OR = 6·91, 95% CI 2·26-21·17). Findings indicate that caregiver and stroke survivor well-being are interdependent. Thus, early interventions, including increased training and support programs that include caregivers, are likely to reduce the risk of negative emotional outcomes. © 2015 World Stroke Organization.

    Double-blind randomized studies on the effects of oral postmenopausal hormone therapies were stopped mainly because of increased risk of stroke. We aimed to assess the risk of all strokes and various subtypes associated with hormone therapy and explore the influence of regimens and routes of administration. A national historical cohort of women aged 51 to 70 years from 1995 to 2010 was established by linking 5 Danish registries. The National Registry of Medicinal Product Statistics provided information on hormone therapy exposure and the National Patient or Cause of Death Registries supplied data regarding stroke diagnoses (ischemic/hemorrhagic/subarachnoid hemorrhage). Multiply adjusted rate ratios with time-varying covariates were fitted in Poisson regression models. Of the 980 003 included women, 20 199 suffered a stroke (78% ischemic, 12% hemorrhagic, and 10% subarachnoid hemorrhage). In total, 36% of women used hormone therapy. Current use conferred a relative rate of 1.16 (95% confidence interval, 1.12-1.22). Compared with never users, the increased rate ratio of all stroke with continuous, cyclic combined estrogen/progestin, and estrogen only oral therapies were 1.29 (95% confidence interval, 1.21-1.37), 1.11 (95% confidence interval, 1.04-1.20), and 1.18 (95% confidence interval, 1.10-1.26), respectively. The increased risk was because of ischemic stroke, but not hemorrhagic stroke. Transdermal application of hormone therapy was not associated with risk of stroke. Vaginal estrogen was associated with a decreased risk of stroke. In a national setting, we found an increased risk of stroke, based on ischemic stroke, with oral hormone therapies that was comparable to findings from randomized studies. We found no risk of stroke with transdermal application and a reduced risk with vaginal estrogen. © 2017 American Heart Association, Inc.

    To implement a mendelian randomization (MR) approach to determine whether type 2 diabetes mellitus (T2D), fasting glucose, fasting insulin, and body mass index (BMI) are causally associated with specific ischemic stroke subtypes. MR estimates of the association between each possible risk factor and ischemic stroke subtypes were calculated with inverse-variance weighted (conventional) and weighted median approaches, and MR-Egger regression was used to explore pleiotropy. The number of single nucleotide polymorphisms (SNPs) used as instrumental variables was 49 for T2D, 36 for fasting glucose, 18 for fasting insulin, and 77 for BMI. Genome-wide association study data of SNP-stroke associations were derived from METASTROKE and the Stroke Genetics Network (n = 18,476 ischemic stroke cases and 37,296 controls). Conventional MR analysis showed associations between genetically predicted T2D and large artery stroke (odds ratio [OR] 1.28, 95% confidence interval [CI] 1.16-1.40, p = 3.3 × 10(-7)) and small vessel stroke (OR 1.21, 95% CI 1.10-1.33, p = 8.9 × 10(-5)) but not cardioembolic stroke (OR 1.06, 95% CI 0.97-1.15, p = 0.17). The association of T2D with large artery stroke but not small vessel stroke was consistent in a sensitivity analysis using the weighted median method, and there was no evidence of pleiotropy. Genetically predicted fasting glucose and fasting insulin levels and BMI were not statistically significantly associated with any ischemic stroke subtype. This study provides support that T2D may be causally associated with large artery stroke. © 2017 American Academy of Neurology.

Materials and Methods. During January 1, 2007, and December 31, 2013, a total of 327,268 T2DM and 307,984 stroke patients were registered on Diabetes and Stroke Surveillance System, respectively. Stroke subtypes were classified according to standard definitions of subarachnoid hemorrhage, intracerebral hemorrhage, and ischemic stroke. The incidence of stroke and stroke subtypes was calculated by standardized incidence ratio (SIRs with 95% confidence intervals (CIs compared with general population. Results. The incidence of stroke and stroke subtypes among patients with T2DM was significantly higher than in general population. Stroke risk was found significantly increased with an SIR of 3.87 (95% CI 3.76–3.99 and 3.38 (95% CI 3.27–3.48 in females and males, respectively. The excess risk of stroke was mainly attributable to the significantly higher risk of cerebral infarctions with the risk for T2DM being four times that for general population. Conclusions. The relationship between stroke and T2DM was strong, especially in female. The incidence of stroke and stroke subtypes among patients with T2DM was up to 3-fold higher than in general population in Zhejiang province, especially the subtype of cerebral infarctions.

    There is uncertainty surrounding the influence of prior antiplatelet agent use on outcomes after intravenous thrombolysis with recombinant tissue plasminogen activator in acute ischemic stroke. We performed a systematic review with a final meta-analysis to evaluate the efficacy and safety of prior antiplatelet use before intravenous recombinant tissue plasminogen activator for acute ischemic stroke. We searched PubMed and Embase databases from 1997 to 2014. Primary outcome was functional outcome at the end of follow-up; secondary outcomes were symptomatic intracranial hemorrhage and recanalization rate. The meta-analysis was performed with Review Manager 5.2 (Copenhagen: The Nordic Cochrane Centre, The Cochrane Collaboration, 2012). Eleven studies with a total of 19,453 patients were included. A total of 6517 (33.5%) patients who had received intravenous recombinant tissue plasminogen activator were taking antiplatelet agent before stroke onset. Pooled analysis demonstrated a clear trend that previous antiplatelet users had a reduced probability of good outcome, although it was not conventionally statistically significant (OR 0.86; 95% CI 0.73-1.01; P = 0.06). There was no difference in recanalization rate between two groups (OR 1.23; 95% CI 0.30-4.99; P = 0.77). The risk of symptomatic intracranial hemorrhage was significantly increased in the antiplatelet group (OR 1.65; 95% CI 1.44-1.90; P acute ischemic stroke patients receiving intravenous recombinant tissue plasminogen activator therapy, prior antiplatelet agent use did not lead to a significant difference in functional outcome, although it significantly increased the risk of symptomatic intracranial hemorrhage. Recanalization rate was not different between two groups. In the subgroup analysis, prior clopidogrel mono therapy may not increase the risk of symptomatic intracranial hemorrhage, which will need further studies to confirm. © 2014 World Stroke Organization.

    Chiropractic manipulation is a popular treatment for neck pain and headache, but may increase the risk of cervical artery dissection and stroke. Patients with carotid artery dissection can present with neck pain and/or headache before experiencing a stroke. These are common symptoms seen by both chiropractors and primary care physicians (PCPs). We aimed to assess the risk of carotid artery stroke after chiropractic care by comparing association between chiropractic and PCP visits and subsequent stroke. A population-based, case-crossover study was undertaken in Ontario, Canada. All incident cases of carotid artery stroke admitted to hospitals over a 9-year period were identified. Cases served as their own controls. Exposures to chiropractic and PCP services were determined from health billing records. We compared 15,523 cases to 62,092 control periods using exposure windows of 1, 3, 7, and 14 days prior to the stroke. Positive associations were found for both chiropractic and PCP visits and subsequent stroke in patients less than 45 years of age. These associations tended to increase when analyses were limited to visits for neck pain and headache-related diagnoses. There was no significant difference between chiropractic and PCP risk estimates. We found no association between chiropractic visits and stroke in those 45 years of age or older. We found no excess risk of carotid artery stroke after chiropractic care. Associations between chiropractic and PCP visits and stroke were similar and likely due to patients with early dissection-related symptoms seeking care prior to developing their strokes.

    Full Text Available Background. Recent studies report that acute stroke patients who present to the hospital on weekends have higher rates of 28-day mortality than similar patients who arrive during the week. However, how this association is related to clinical presentation and stroke type has not been systematically investigated. Methods and Results. We examined the association between day of arrival and 28-day mortality in 929 validated stroke events in the ARIC cohort from 1987–2004. Weekend arrival was defined as any arrival time from midnight Friday until midnight Sunday. Mortality was defined as all-cause fatal events from the day of arrival through the 28th day of followup. The presence or absence of thirteen stroke signs and symptoms were obtained through medical record review for each event. Binomial logistic regression was used to estimate odds ratios and 95% confidence intervals (OR; 95% CI for the association between weekend arrival and 28-day mortality for all stroke events and for stroke subtypes. The overall risk of 28-day mortality was 9.6% for weekday strokes and 10.1% for weekend strokes. In models controlling for patient demographics, clinical risk factors, and event year, weekend arrival was not associated with 28-day mortality (0.87; 0.51, 1.50. When stratified by stroke type, weekend arrival was not associated with increased odds of mortality for ischemic (1.17, 0.62, 2.23 or hemorrhagic (0.37; 0.11, 1.26 stroke patients. Conclusions. Presence or absence of thirteen signs and symptoms was similar for weekday patients and weekend patients when stratified by stroke type. Weekend arrival was not associated with 28-day all-cause mortality or differences in symptom presentation for strokes in this cohort.

    Falls are common after stroke, with potentially serious consequences. Few investigations have included age-matched control participants to directly compare fall characteristics between older adults with and without stroke. Further, fear of falling, a significant psychological consequence of falls, has only been examined to a limited degree as a risk factor for future falls in a stroke population. To compare the fall history between older adults with and without a previous stroke and to identify the determinants of falls and fear of falling in older stroke survivors. Case-control observational study. Primary teaching hospital. Seventy-five patients with stroke (mean age ± standard deviation, 66 ± 7 years) and 50 age-matched control participants with no previous stroke were tested. Fall history, fear of falling, and physical, cognitive, and psychological function were assessed. A χ(2) test was performed to compare characteristics between groups, and logistic regression was performed to determine the risk factors for falls and fear of falling. Fall events in the past 12 months, Fall Efficacy Scale-International, Berg Balance Scale, Functional Ambulation Category, Fatigue Severity Scale, Montreal Cognitive Assessment, and Patient Healthy Questionnaire-9 were measured for all participants. Fugl-Meyer Motor Assessment was used to quantify severity of stroke motor impairments. Twenty-three patients and 13 control participants reported at least one fall in the past 12 months (P = .58). Nine participants with stroke had recurrent falls (≥2 falls) compared with none of the control participants (P control participants (P < .01). Female gender was associated with falls in the nonstroke group, whereas falls in the stroke group were not significantly associated with any measured outcomes. Fear of falling in the stroke group was associated with functional ambulation level and balance. Functional ambulation level alone explained 22% of variance in fear of falling in the

    Full Text Available Fatigue is often reported in stroke patients. However, it is still unclear if fatigue in stroke patients is more prominent, more frequent or more typical than in patients with multiple sclerosis (MS and if the pathophysiology differs between these two populations. The purpose of this study was to compare motor fatigue and fatigue induced changes in kinematic gait parameters between stroke patients, MS patients and healthy persons. Gait parameters at the beginning and end of a treadmill walking test were assessed in 10 stroke patients, 40 MS patients and 20 healthy subjects. The recently developed Fatigue index Kliniken Schmieder (FKS based on change of the movement’s attractor and its variability was used to measure motor fatigue. Six stroke patients had a pathological FKS. The FKS (indicating the level of motor fatigue in stroke patients was similar compared to MS patients. Stroke patients had smaller step length, step height and greater step width, circumduction with the right and left leg as well as greater sway compared to the other groups at the beginning and at the end of test. A severe walking impairment in stroke patients does not necessarily cause a pathological FKS indicating motor fatigue. Moreover, the FKS can be used as a measure of motor fatigue in stroke and MS and may also be applicable to other diseases.

    Full Text Available BACKGROUND AND PURPOSE: Mild to moderate ischemic stroke is a common presentation in the outpatient setting. Among the various subtypes of stroke, lacunar infarction (LI is generally very common. Currently, little is known about the long-term prognosis and factors associated with the prognosis between LI and non-LI. This study aims to compare the risk of death and acute cardiovascular events between patients with LI and non-LI, and identify potential risk factors associated with these outcomes. METHODS: A total of 710 first-ever ischemic stroke patients (LI: 474, non-LI: 263 from 18 clinics were recruited consecutively from 2003 to 2004. They were prospectively followed-up until the end of 2008. Hazard ratios and 95% confidence intervals were calculated using multivariable Cox proportional hazards regression. RESULTS: After a 5-year follow up, 54 deaths and 96 acute cardiovascular events occurred. Recurrent stroke was the most common cause of death (19 cases, 35.18% and new acute cardiovascular events (75 cases, 78.13%. There were no significant differences between patients with LI and non-LI in their risks of death, new cardiovascular events, and recurrent stroke after adjusting for age, sex, hypertension, diabetes, cardiac diseases, body mass index, dyslipidemia, smoking, alcohol consumption, ADL dependence, and depressive symptoms. Among the modifiable risk factors, diabetes, hypertension, ADL dependency, and symptoms of depression were independent predictors of poor outcomes in patients with LI. In non-LI patients, however, no modifiable risk factors were detected for poor outcomes. CONCLUSION: Long-term outcomes did not differ significantly between LI and non-LI patients. Detecting and managing vascular risk factors and depression as well as functional rehabilitation may improve the prognoses of LI patients.

    Medication-related osteonecrosis of the jaw (ONJ) is often preceded by dentoalveolar trauma. The aim of this study was to examine the frequency of dentoalveolar trauma precipitated ONJ and compare trauma-precipitated ONJ with spontaneously developing ONJ. This was a retrospective study. All patients were examined according to a standard ONJ chart. Among 149 consecutive ONJ patients from the Copenhagen Cohort, 95 (64%) had a dentoalveolar trauma before referral (trauma group): dental extractions (n = 80); denture-related sore mouth (n = 12); and others (n = 3). The remaining 54 patients had spontaneous ONJ (spontaneous group). The mean time from oral trauma to referral for ONJ was 8 months. This study documented that dentoalveolar trauma precipitated ONJ in the majority of cases. However, even minor trauma, such as intubation and impression tray lesions, precipitated ONJ in a few cases (1%). Besides the occurrence of fistula to the skin and a difference in the male-to-female ratio, we found no significant difference between the spontaneous and trauma groups.

    A thought experiment, proposed by Karl Popper, which has been experimentally realized recently, is critically examined. A basic flaw in Popper's argument which has also been prevailing in subsequent debates, is pointed out. It is shown that Popper's experiment can be understood easily within the Copenhagen interpretation of quantum mechanics. An alternate experiment, based on discrete variables, is proposed, which constitutes Popper's test in a clearer way. It refutes the argument of absence of nonlocality in quantum mechanics.

    2011-03-15

    A year after the grim UN climate change negotiations in Denmark that resulted in parties merely 'taking note' of a three-page 'Copenhagen Accord', 194 countries met in Cancun, Mexico. Unlike the furore surrounding the Copenhagen negotiations, expectations were comparatively low-key for Cancun. The Copenhagen conference had damaged faith in the UN climate convention as an effective and legitimate negotiating forum. Restoring confidence in this process was a priority for Cancun. Parties were seeking a modest but balanced outcome across all main elements of the 2007 Bali Action Plan (BAP) which includes adaptation, mitigation, finance, technology, and capacity building. By the end of the two week negotiations, countries had finalized the 'Cancun Agreements', which managed to encompass decisions on each part of the BAP. In addition, the conference was widely recognized as having rebuilt fractured negotiating relationships between parties. The conference proceedings focused on the ongoing efforts of the two ad-hoc working groups that were established to find ways to enhance implementation of the convention and to discuss future commitments under the Kyoto Protocol.

    Full Text Available Abstract Background Recovery patterns of upper extremity motor function have been described in several longitudinal studies, but most of these studies have had selected samples, short follow up times or insufficient outcomes on motor function. The general understanding is that improvements in upper extremity occur mainly during the first month after the stroke incident and little if any, significant recovery can be gained after 3-6 months. The purpose of this study is to describe the recovery of upper extremity function longitudinally in a non-selected sample initially admitted to a stroke unit with first ever stroke, living in Gothenburg urban area. Methods/Design A sample of 120 participants with a first-ever stroke and impaired upper extremity function will be consecutively included from an acute stroke unit and followed longitudinally for one year. Assessments are performed at eight occasions: at day 3 and 10, week 3, 4 and 6, month 3, 6 and 12 after onset of stroke. The primary clinical outcome measures are Action Research Arm Test and Fugl-Meyer Assessment for Upper Extremity. As additional measures, two new computer based objective methods with kinematic analysis of arm movements are used. The ABILHAND questionnaire of manual ability, Stroke Impact Scale, grip strength, spasticity, pain, passive range of motion and cognitive function will be assessed as well. At one year follow up, two patient reported outcomes, Impact on Participation and Autonomy and EuroQol Quality of Life Scale, will be added to cover the status of participation and aspects of health related quality of life. Discussion This study comprises a non-selected population with first ever stroke and impaired arm function. Measurements are performed both using traditional clinical assessments as well as computer based measurement systems providing objective kinematic data. The ICF classification of functioning, disability and health is used as framework for the selection of

    Stroke represents a global challenge and is a leading cause of permanent disability worldwide. Despite much effort, translation of research findings to clinical benefit has not yet been successful. Failure of neuroprotection trials is considered, in part, due to the low quality of preclinical studies, low level of reproducibility across different laboratories and that stroke co-morbidities have not been fully considered in experimental models. More rigorous testing of new drug candidates in different experimental models of stroke and initiation of preclinical cross-laboratory studies have been suggested as ways to improve translation. However, to our knowledge, no drugs currently in clinical stroke trials have been investigated in preclinical cross-laboratory studies. The cytokine interleukin 1 is a key mediator of neuronal injury, and the naturally occurring interleukin 1 receptor antagonist has been reported as beneficial in experimental studies of stroke. In the present paper, we report on a preclinical cross-laboratory stroke trial designed to investigate the efficacy of interleukin 1 receptor antagonist in different research laboratories across Europe. Our results strongly support the therapeutic potential of interleukin 1 receptor antagonist in experimental stroke and provide further evidence that interleukin 1 receptor antagonist should be evaluated in more extensive clinical stroke trials.

    Large cohort studies on relationship between family history of stroke (FHS) and stroke risk are lacking in Asians. We aimed to systematically evaluate the association of FHS with stroke risk in a cohort study of 0.5 million Chinese adults. Information about FHS was self-reported. The median follow-up time was 7.16 years and the end-point of follow-up was incident stroke, which was entered directly into the China Kadoorie Biobank system. Multivariate analyses were performed with Cox proportional hazards model, and interaction analyses were carried using likelihood-ratio tests. Compared with participants without FHS, the hazard ratio (HR) (95% confidence interval, CI) of stroke for participants with FHS was 1.50 (1.46-1.55). The HRs increased with the number of first degree relatives with stroke (HRs=1.41, 1.98 and 2.47 for 1, 2 and ≥3 relatives, respectively, Ptrend history and parental history, respectively. Similar associations with offspring stroke risk were observed between paternal history (HR=1.48, 95% CI: 1.43-1.54) and maternal history (HR=1.49, 95% CI: 1.43-1.55). Moreover, significant interactions were detected between FHS and health-risk behaviors (tobacco smoking and alcohol drinking). FHS is an independent risk factor for stroke in Chinese. The more first degree relatives are affected by stroke, the higher are individuals' risk of suffering from stroke. The management of the health-risk behaviors for reducing stroke should be highlighted, especially for the individuals with FHS.

    Haplotypes of the fibrinogen gamma and alpha (FGG and FGA) genes are associated with the structure of the fibrin network and may therefore influence the risk of stroke. We investigated the relationship between common variation in these genes with ischemic and haemorrhagic stroke. The study was based on 6,275 participants of the prospective population-based Rotterdam Study who at baseline (1990-1993) were aged 55 years or over, free from stroke, and had successful assessment of at least one FGG or FGA single nucleotide polymorphisms (SNP). Common haplotypes were estimated using seven tagging SNPs across a 30 kb region containing the FGG and FGA genes. Follow-up for incident stroke was complete until January 1, 2005. Associations between constructed haplotypes and risk of stroke were estimated with an age- and sex-adjusted logistic regression model. We observed 668 strokes, of which 393 were ischemic and 62 haemorrhagic, during a median follow-up time of 10.1 years. FGG + FGA haplotype 3 (H3) was associated with an increased risk of ischemic stroke (odds ratio [OR] 1.36, 95% confidence interval [CI] 1.09-1.69) and the risk estimate for hemorrhagic stroke was 0.71 (95% CI 0.46-1.09) compared to the most frequent H1. The FGG and FGA genes were not associated with stroke or its subtypes when analyzed separately. In conclusion, risk of ischemic stroke was higher in FGG + FGA H3 than in H1. The results suggested that an opposite association may exist for haemorrhagic stroke.

    2014-04-01

    In this paper the city of Copenhagen is used as a starting point to highlight some critical historical events, both concerning the exchange of ideas between the physicist Wolfgang Pauli and C.G. Jung and the history of psychotherapy in Scandinavia. Pauli's years in Copenhagen under the influence of Niels Bohr and his philosophy prepared him mentally to receiveC.G. Jung's ideas. The paper also recounts the one occasion that Jung was in Scandinavia, attending the 9th conference of the General Medical Society for Psychotherapy in Copenhagen, just before going to New York in 1937 to give his final seminars on Pauli's dreams. The reason for focusing on these particular events is that they also constitute part of the history of the reception of psychodynamic psychology in Sweden and Scandinavia. © 2014, The Society of Analytical Psychology.

    The objective of this pilot study was to explore whether organisational change and work-related stress, as measured by the Job Content Questionnaire, were associated with first-ever stroke among working people aged 30-65. In a case-control study a total of 65 consecutive cases, aged 30-65 years of age, with first-ever stroke were recruited from four hospitals in Sweden during 2000-2002. During the same period, 103 random population controls in the same age interval were recruited. Data on job-related stress and traditional medical risk factors were collected by a questionnaire. In the multivariate analyses, organisational change (OR 3.38) increased the likelihood of stroke, while experiencing an active job (OR 0.37) decreased the likelihood of stroke. Regarding risk factors outside work, age (OR 1.11), low physical activity (OR 5.21), low education (OR 2.48) and family history of stroke (OR 2.59) were associated with increased likelihood of stroke. This study suggests an association between organisational change, work-related stress and stroke. The likelihood of stroke was lower for people in active job situations.

    Qualitative data can add value and understanding to more traditional epidemiological studies. This study was designed to complement the quantitative data from the incidence study the Auckland Regional Community Stroke Study or ARCOS-IV by using qualitative methods to uncover the richer detail of life as a stroke survivor, thereby extending our understanding of the impact of stroke. The aims of the study were to identify how the experience of recovery and adaptation changes over time after stroke; and to elicit the strategies people with stroke and their whānau/family use and find helpful in living life after stroke. The aim of this paper is to describe the methodology and also the challenges and advantages of embedding qualitative research into a large epidemiological study. Longitudinal study utilizing a Qualitative Description design in a subset of those taking part in the incidence study. Participants will be interviewed at 6, 12, 24, and 36 months after stroke. Semistructured interviews will explore three key areas: (1) issues of importance to people following a stroke and their whānau/family; (2) the perceived impact on people's sense of recovery, adaptation, and hopes; and (3) key strategies that people with stroke and their whānau/family use and find most helpful in living life after stroke. Thematic analysis will be conducted using iterative constant comparative methods. This methodology paper demonstrates the application of mixed methods in epidemiology. It also considers some of the practical and methodological issues that have emerged and may provide a useful framework for other qualitative projects in population-based studies. © 2013 The Authors.

    Full Text Available Objective To investigate the relationship between serum cystatin C (Cys C and patients with acute ischemic stroke. Methods The clinical and laboratory data of 115 patients with acute ischemic stroke and 110 controls were recorded and analyzed. Results The serum Cys C levels of patients in ischemic stroke group [(1.15 ± 0.34 mg/L] were higher than that of the control group [(0.99 ± 0.25 mg/L]. The difference between two groups was significant after correction of age and cardiovascular risk factors (t = ? 3.889, P = 0.000. It was found that age, Cys C, homocysteine (Hcy, type 2 diabetes mellitus [hemoglobin A1c (HbA1c, fructosamine (FRU], smoking, alcohol consumption, hypertension and intima-media thickness (IMT were risk factors for ischemic stroke on univariate Logistic regression analysis. The difference of serum Cys C level between the patients and controls was significant (P = 0.000, but through covariance analysis, after adjusted other risk factors, it was not significant (P = 0.875. Conclusion The serum Cys C levels of patients in ischemic stroke group is higher than the control group. It can be used as an indicator in the acute phase of ischemic stroke. The elevation of serum Cys C is a risk factor for ischemic stroke, but not an independent risk factor.

    Little is known about the acute precipitants of ischemic stroke, although evidence suggests infections contribute to risk. We hypothesized that acute hospitalization for infection is associated with the short-term risk of stroke. The case-crossover design was used to compare hospitalization for infection during case periods (90, 30, or 14 days before an incident ischemic stroke) and control periods (equivalent time periods exactly 1 or 2 years before stroke) in the Cardiovascular Health Study, a population-based cohort of 5888 elderly participants from 4 US sites. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated by conditional logistic regression. Confirmatory analyses assessed hazard ratios of stroke from Cox regression models, with hospitalization for infection as a time-varying exposure. During a median follow-up of 12.2 years, 669 incident ischemic strokes were observed in participants without a baseline history of stroke. Hospitalization for infection was more likely during case than control time periods; for 90 days before stroke, OR=3.4 (95% CI, 1.8 to 6.5). The point estimates of risks were higher when we examined shorter intervals: for 30 days, OR=7.3 (95% CI, 1.9 to 40.9), and for 14 days, OR=8.0 (95% CI, 1.7 to 77.3). In survival analyses, risk of stroke was associated with hospitalization for infection in the preceding 90 days, adjusted hazard ratio=2.4 (95% CI, 1.6 to 3.4). Hospitalization for infection is associated with a short-term increased risk of stroke, with higher risks observed for shorter intervals preceding stroke.

    Objective:To determine the association between tea consumption and the risk of stroke.Methods:We searched the PubMed database from January 1966 to March 2012 and reviewed reference lists of retrieved articles to identify relevant studies.Studies were included if they reported relative risks (RRs) and corresponding 95% confidence intervals (CIs) of stroke with respect to three or more categories of tea consumption.A random-effects model was used to combine the study-specific risk estimates.Results:Fourteen studies,consisting of 513 804 participants with a median follow-up of 11.5 years,were included in this meta-analysis.We observed a modest but statistically significant inverse association between tea consumption and risk of stroke.An increase of three cups/d in tea consumption was associated with a 13% decreased risk of stroke (RR 0.87; 95% CI,0.81-0.94).The decreased risk of stroke with tea consumption was consistent among most subgroups.Based on the three studies that provided results for stroke subtypes,tea consumption was also inversely associated with the risk of ischemic stroke (RR 0.76; 95% CI,0.69-0.84),but not cerebral hemorrhage (RR 0.96; 95% CI,0.82-1.11 ) or subarachnoid hemorrhage (RR 0.81 ; 95% CI,0.57-1.16).Conclusions:Tea consumption is associated with a decreased risk of stroke,particularly ischemic stroke.More well-designed,rigorously conducted studies are needed in order to make confident conclusions about the association between tea consumption and stroke subtypes.

    2003-12-01

    Vital exhaustion, a psychological measure characterized by fatigue and depressive symptoms, has been suggested to be an independent risk factor for ischaemic heart disease (IHD) but the generality of the phenomenon remains in question. The aim of this study is to describe prevalence of these symptoms in a community sample and determine whether they prospectively predict increased risk of IHD and all-cause mortality in men and women. The study base was 4084 men and 5479 women aged 20-98 free of IHD examined in 1991-1993 in the Copenhagen City Heart Study. Events were ascertained through record linkage until 1998 for IHD and September 2000 for all-cause mortality. There were 483 first hospital admissions and deaths caused by IHD and 1559 deaths from all causes during follow-up. The 17 items on the vital exhaustion questionnaire were frequently endorsed with prevalence ranging from 6 to 47 per cent, higher in women. All but 4 of the 17 items were significantly associated with IHD with significant relative risks (RR) ranging between 1.36 (95% CI: 1.08, 1.72) and 2.10 (95% CI: 1.63, 2.71). Associations with all-cause mortality were also observed, but were weaker. RR of both IHD and all-cause mortality increased with increasing item sum score and were similar in men and women. For IHD, RR reached a maximum of 2.57 (95% CI: 1.65, 4.00) for subjects endorsing >9 items. The similar RR for all-cause mortality was 2.50 (95% CI: 2.09, 2.99). Multivariate adjustment for biological, behavioural, and socioeconomic risk factors did not substantially affect the association for IHD but attenuated the association with all-cause mortality. Measures of fatigue and depression were common symptoms in this population sample and convey increased risk of IHD and of all-cause mortality. We propose this knowledge begin to be implemented in risk assessment in clinical practice.

  6. The units of measurement of the ventricular stroke work: a review study.

    Science.gov (United States)

    Schramm, Wolfgang

    2010-06-01

    The ventricular stroke work refers to the work done by the left or right ventricle to eject the volume of blood during one cardiac cycle, called stroke volume. Sarnoff and Berglund were one of the first to calculate the stroke work from the pressure volume diagram in 1954. However, they published a wrong unit of measurement for the stroke work, namely gram meter. The present work reviewed 779 scientific publications between May 1954 and January 2010 which used the left or right ventricular stroke work as a variable. Interestingly, the majority (87.2%) of scientific papers since 1954 have either copied this (or a similar) wrong unit of measurement or have invented another one. Only 12.8% of the publications gave a correct unit. The present search in scientific literature demonstrates that the haemodynamic variable ventricular stroke work, which is used daily by thousands of medical doctors and scientists, was specified in an incorrect manner for 56 years in the majority of scientific papers. A correct unit of measurement, of course, is an imperative condition when comparing scientific papers. The aim of this publication is the elimination of incorrect units of measurement of the ventricular stroke work variable in all future scientific papers. Moreover, the present work facilitates the interpretation of at least some of the studies containing the ventricular stroke work variable published up to now.

    Patent foramen ovale (PFO) is a common congenital anatomical defect in the general population with a mean prevalence of 20 %. Transcranial Doppler sonography and echocardiography, both with infusion of agitated saline as an echo contrast, have been introduced for the diagnosis of PFO. Transesophageal echocardiography is considered the gold standard. Several studies have suggested an association between cryptogenetic stroke and PFO, but the role of this condition as a risk factor for stroke is still debated. The aims of this prospective multicentre study are the evaluation of PFO prevalence in the whole ischemic stroke population and the identification of a stroke recurrence profile risk in patients with PFO. All consecutive patients admitted for acute ischemic stroke and with a confirmed diagnosis at discharge are eligible cases for the study. Demographic and vascular risk factors are registered. Clinical severity is summarized by the National Institute of Health stroke scale. Echocardiographic and transcranial studies are performed in each patient to detect the presence of PFO. Prevalence of PFO will be calculated with 95 % CIs. Univariate analysis will be performed to detect the correlation of PFO with different registered factors and multivariable analysis with PFO as independent variable. The present study should contribute to better identify the role of PFO in ischemic stroke risk and recurrence-related events. Qualifying findings of the study are represented by the high number of enrolled patients, the prospective methodology of the study and the presence of secondary instrumental endpoints.

    Terttu Heikinheimo

    Full Text Available BACKGROUND: Stroke contributes significantly to disability and mortality in developing countries yet little is known about the determinants of stroke outcomes in such countries. 12% of Malawian adults have HIV/AIDS. It is not known whether having HIV-infection alters the outcome of stroke. The aim of this study was to document the functional outcome and mortality at 1 year of first-ever acute stroke in Malawi. Also to find out if the baseline variables, including HIV-infection, affect the outcome of stroke. METHODS AND FINDINGS: 147 adult patients with first-ever acute stroke were prospectively followed up for 12 months. Conventional risk factors and HIV-infection were assessed at baseline. Stroke severity was evaluated with modified National Institute of Health Stroke Scale (mNIHSS and functional outcome with modified Rankin scale (mRS. Fifty (34% of patients were HIV-seropositive. 53.4% of patients had a poor outcome (severe disability or death, mRS 4-6 at 1 year. Poor outcome was related to stroke severity and female gender but not to presence of HIV-infection. HIV-seropositive patients were younger and had less often common risk factors for stroke. They suffer more often ischemic stroke than HIV-seronegative patients. CONCLUSIONS: Mild stroke and male gender were associated with favourable outcome. HIV-infection is common in stroke patients in Malawi but does not worsen the outcome of stroke. However, it may be a risk factor for ischemic stroke for young people, who do not have the common stroke risk factors. Our results are significant, because stroke outcome in HIV-seropositive patients has not been studied before in a setting such as ours, with very limited resources and a high prevalence of HIV.

    This review aimed to determine the association between periodontal disease and stroke incidence by a meta-analysis of cohort studies. Cohort studies that evaluated the incidence of stroke (fatal or non-fatal, ischaemic or haemorrhagic) and baseline periodontal status and calculated relative risk values were included. The quality of the included studies was assessed using an evaluation grid. The analyses were conducted separately for three outcomes: periodontitis, gingivitis and loss of teeth. Adjusted values of relative risk or of hazard ratio were used to assess risk values in each study. Random effects meta-analyses were conducted when data could be pooled. From the 743 references retrieved, only nine cohort studies were suitable for inclusion in this review. Quality scores of the studies varied greatly. Three prospective studies, which used reliable indicators of periodontal disease, obtained the highest scores. Conversely, three studies that used a subjective evaluation of stroke incidence or diagnosed stroke without imaging obtained the lowest score. The results of the meta-analyses varied depending on the outcome considered and the type of stroke. The risk of stroke was significantly increased by the presence of periodontitis [relative risk 1.63 (1.25, 2.00)]. Tooth loss was also a risk factor for stroke [relative risk 1.39 (1.13, 1.65)]. The risk of stroke did not vary significantly with the presence of gingivitis. This review shows that periodontitis and tooth loss are associated with the occurrence of stroke. © 2014 The Author(s) European Journal of Neurology © 2014 EAN.

  2. Karl Popper and the Copenhagen interpretation

    Science.gov (United States)

    Peres, Asher

    Popper conceived an experiment whose analysis led to a result that he deemed absurd. Popper wrote that his reasoning was based on the Copenhagen interpretation and therefore invalidated it. Many authors who have examined Popper's analysis have found in it various technical flaws which are briefly summarized here. However, the aim of the present article is not technical. My concern is to redress logical flaws in Popper's argument: the terminology he uses is ambiguous, his analysis involves counterfactual hypotheses, and it violates Bohr's complementarity principle. Therefore, the absurdity of Popper's result only confirms Bohr's approach.

    Yanfang Liu

    Full Text Available Previous studies have suggested that C-reactive protein (CRP was associated with risk of stroke. There were few studies in Asian population, or on stroke subtypes other than ischemic stroke. We thus investigated the relationship between CRP and the risks of all stroke and its subtypes in a Chinese adult population.In the current study, we included 90,517 Chinese adults free of stroke and myocardial infarction at baseline (June 2006 to October 2007 in analyses. Strokes were classified as ischemic stroke (IS, intracranial heamorrhage (ICH and subarachnoid heamorrhage (SAH. High-sensitivity CRP (hs-CRP were categorized into three groups: 3 mg/L. Cox proportional hazards regression was used to calculate the association between hs-CRP concentrations and all stroke, as well as its subtypes.During a median follow-up time of 49 months, we documented 1,472 incident stroke cases. Of which 1,049 (71.3% were IS, 383 (26.0% were ICH, and 40 (2.7% were SAH. After multivariate adjustment, hs-CRP concentrations ≥1 mg/L were associated with increased risks of all stroke (hs-CRP 1-3 mg/L: hazard ratio (HR 1.17, 95% confidential interval (CI 1.03-1.33; hs-CRP>3 mg/L: HR 1.25, 95% CI 1.07-1.46 and IS (hs-CRP 1-3 mg/L: HR 1.17, 95% CI 1.01-1.36; hs-CRP>3 mg/L: HR 1.33, 95% CI 1.11-1.60, but not with ICH and SAH. Subgroup analyses showed that higher hs-CRP concentration was more prone to be a risk factor for all stroke and IS in non-fatal stroke, male and hypertensive participants.We found that higher hs-CRP concentrations were associated with a higher risk of IS, particularly for non-fatal stroke, male and hypertensive subjects. In contrast, we did not observe significant associations between hs-CRP and ICH/SAH.

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

    2015-01-01

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

    2006-01-01

    Studies on the interaction between physiotherapists and patients during treatment sessions have found low levels of communicative participation by patients and lack of direct influence by patients on the content of their treatment. This article reports the results of 7 counseling sessions in which physiotherapists and patients with stroke and their caregivers discussed the patients' postural control and balance, which had been tested and videotaped at different stages of the rehabilitation process. The physiotherapists' discourses relating to the videotaped test performances were either brief comments on the patient's performance or critical appraisals with references to difficulties encountered during performance. Performances of the easier tasks were treated by the physiotherapists with rhetorical questions. The second type of discourse consisted of the physiotherapists directing the patients' attention to their problems, and of the patients' and caregivers' initiatives leading to conversation about the patients' problems. The patients understood the significance of the test performance for their life at home in varying ways. The results of this study showed that successful counseling calls for physiotherapists to develop dialogic communication skills to help patients in coconstructing their home exercise together with their social network.

    BACKGROUND: Uncertainty remains about whether stroke affects men and women similarly. We studied differences between men and women with regard to stroke severity and survival. METHODS AND RESULTS: We used the Danish Stroke Registry, with information on all hospital admissions for stroke in Denmark...... between 2003 and 2012 (N=79 617), and the Danish Register of Causes of Death. Information was available on age, sex, marital status, stroke severity, stroke subtype, socioeconomic status, and cardiovascular risk profile. We studied only deaths due to the index stroke, with the assumption that death...... reported on death certificates as due to stroke was related to the index stroke if death occurred within the first week or month after stroke. Multivariate Cox regression analysis and multiple imputation were applied. Stroke was the cause of death for 4373 and 5512 of the 79 617 patients within 1 week (5...

    Full Text Available Abstract Background Successful return to work is regarded as one of the most important outcome factors for working-age post stroke patients. The present study will estimate the effect of various predictors on the odds of returning to work after stroke. Nearly twenty thousand 20-57 year-old stroke patients in Denmark who were gainfully occupied prior to the stroke will be included in the study. Methods/design Stroke patients will be followed prospectively through national registers. Multi-level logistic regression will be used to model the odds of being gainfully occupied ca. two years after the stroke as a function of the following predictors: Age (20-49 years, 50-57 years gender, occupational class, self-employment (yes; no, onset calendar year (1996, 1997, ..., 2006, diagnosis (subarachnoid haemorrhage; intracerebral haemorrhage; cerebral infarction; stroke, not specified as haemorrhage or infarction and 'type of municipality' (the variable is set to 1 if the person lived in a municipality which had a brain injury rehabilitation centre at the time of the stroke. Otherwise it is set to 0. Municipalities will be treated as the subjects while individual observations within municipalities are treated as correlated repeated measurements. Discussion Since our follow-up is done through registers and all people in the target population are included, the study is free from sampling bias, recall bias and non-response bias. The study is also strengthened by its size. The major weakness of the study is that it does not contain any stroke severity measures. Thus, it cannot accurately predict whether a particular stroke patient will in fact return to work. The study is, however, quite useful from a public health perspective. It can be used to estimate the proportion of patients in a certain group that is expected to return to work, and thereby provide a comparison material, which e.g. municipalities can use to evaluate their success in returning their

    The association between spontaneous pneumothorax (SP) and stroke has not been reported, and this study aimed to explore this association. We used the National Health Insurance Research Database for conducting a nationwide, population-based, retrospective cohort study of patients newly hospitalized for SP from 2000 to 2010. A total of 2541 patients with newly diagnosed SP were included and compared with patients without SP. We observed that patients with SP were at higher risk for developing stroke, with an adjusted hazard ratio (HR) of 1.56. In addition, these patients had a significantly higher risk of hemorrhagic stroke (adjusted HR = 2.22) than of ischemic stroke (adjusted HR = 1.48). The risk of stroke was the highest in the initial 4 months after hospitalization for SP (adjusted HR = 3.41, 95% confidence interval = 1.98-5.87). In conclusion, our study revealed a correlation between stroke and a history of SP, and the risk of stroke after SP was time sensitive.

    2016-12-01

    In recent years, there has been considerable research interest in the study of brain connectivity using the resting state functional magnetic resonance imaging (rsfMRI). Studies have explored the brain networks and connection between different brain regions. These studies have revealed interesting new findings about the brain mapping as well as important new insights in the overall organization of functional communication in the brain network. In this paper, after a general discussion of brain networks and connectivity imaging, the brain connectivity and resting state networks are described with a focus on rsfMRI imaging in stroke studies. Then, techniques for preprocessing of the rsfMRI for stroke patients are reviewed, followed by brain connectivity processing techniques. Recent research on brain connectivity using rsfMRI is reviewed with an emphasis on stroke studies. The authors hope this paper generates further interest in this emerging area of computational neuroscience with potential applications in rehabilitation of stroke patients.

    the number of nonagenarians increases dramatically worldwide. to examine the prevalence of stroke/transient ischaemic attack (TIA) and dementia, their inter-relationship and their relation to 2-year mortality and institutionalisation in 97 year olds. a population-based sample of 97 year olds (n=591) was examined. Information on stroke/TIA was obtained from self-reports, key informants and hospital discharge registers. Dementia was diagnosed according to DSM-III-R criteria. the response rate was 65%. The prevalence of dementia was 32.7% in men and 59.3% in women (P<0.001). The prevalence of stroke/TIA was 21.5% (17.8% in men, 22.3% in women). Stroke/TIA was related to dementia in women (odds ratio=1.9, 95% CI: 1.2-3.0), but not in men. Dementia, but not stroke/TIA, was related to 2-year mortality and institutionalisation in logistic regression models. dementia was very common in this age group, and related to mortality and institutionalisation. Stroke/TIA in 97 year olds showed less association with dementia, mortality and institutionalisation than reported in studies of younger elderly populations. The finding that stroke was not associated with dementia in men needs to be taken cautiously due to the small number of men. The findings also emphasise that more studies are needed to scrutinise the aetiology of dementia in nonagenarians.

    Few prospective studies have investigated the relationship between spousal cigarette smoking and the risk of incident stroke. Stroke-free participants in the U.S.-based Health and Retirement Study (HRS) aged >or=50 years and married at baseline (n=16,225) were followed, on average, 9.1 years between 1992 and 2006) for proxy or self-report of first stroke (1,130 events). Participants were stratified by gender and own smoking status (never-smokers, former smokers, or current smokers), and the relationship assessed between the spouse's smoking status and the risk of incident stroke. Analyses were conducted in 2007 with Cox proportional hazards models. All models were adjusted for age; race; Hispanic ethnicity; Southern birthstate; parental education; paternal occupation class; years of education; baseline income; baseline wealth; obesity; overweight; alcohol use; and diagnosed hypertension, diabetes, or heart disease. Having a spouse who currently smoked was associated with an increased risk of first stroke among never-smokers (hazard ratio=1.42, 95% CI=1.05, 1.93) and former smokers (hazard ratio=1.72, 95% CI=1.33, 2.22). Former smokers married to current smokers had a stroke risk similar to respondents who themselves smoked. Spousal smoking poses important stroke risks for never-smokers and former smokers. The health benefits of quitting smoking likely extend to both the individual smoker and his or her spouse.

    Although perfusion CT (PCT) for the detection of supratentorial stroke is well established, there is a dearth of evidence of its effectiveness in the detection of infratentorial stroke. Hence, this study compared sensitivity, specificity, and accuracy of PCT maps between infratentorial and supratentorial stroke lesions. One hundred patients with acute stroke who had successfully undergone near whole-brain PCT with the toggling table technique and follow-up MRI were included. Wilcoxon Mann-Whitney test was performed at P < 0.01. There was no significant statistical difference in the accuracy (91.79% vs. 93.23% in regional cerebral blood volume; 92.26% vs. 95.31% in regional cerebral blood flow; 89.17% vs. 92.71% in mean transit time; 89.76% vs. 92.19% in time to peak; P > 0.01 in all PCT maps) between supratentorial and infratentorial stroke. Also, there was no remarkable difference in both sensitivity and specificity of PCT maps. This was the first study to investigate the accuracy of PCT with the toggling table technique in detection of infratentorial stroke lesions. Clinically, PCT is highly reliable and accurate in detecting infratentorial stroke lesions. (orig.)

    Objective End-stage coagulation and the structure/function of fibrin are implicated in the pathogenesis of ischemic stroke. We explored whether genetic variants associated with end-stage coagulation in healthy REFVIDunteers account for the genetic predisposition to ischemic stroke and examined their influence on stroke subtype. Methods Common genetic variants identified through genome-wide association studies of coagulation factors and fibrin structure/function in healthy twins (n = 2,100, Stage 1) were examined in ischemic stroke (n = 4,200 cases) using 2 independent samples of European ancestry (Stage 2). A third clinical collection having stroke subtyping (total 8,900 cases, 55,000 controls) was used for replication (Stage 3). Results Stage 1 identified 524 single nucleotide polymorphisms (SNPs) from 23 linkage disequilibrium blocks having significant association (p < 5 × 10–8) with 1 or more coagulation/fibrin phenotypes. The most striking associations included SNP rs5985 with factor XIII activity (p = 2.6 × 10–186), rs10665 with FVII (p = 2.4 × 10–47), and rs505922 in the ABO gene with both von Willebrand factor (p = 4.7 × 10–57) and factor VIII (p = 1.2 × 10–36). In Stage 2, the 23 independent SNPs were examined in stroke cases/noncases using MOnica Risk, Genetics, Archiving and Monograph (MORGAM) and Wellcome Trust Case Control Consortium 2 collections. SNP rs505922 was nominally associated with ischemic stroke (odds ratio = 0.94, 95% confidence interval = 0.88–0.99, p = 0.023). Independent replication in Meta-Stroke confirmed the rs505922 association with stroke, beta (standard error, SE) = 0.066 (0.02), p = 0.001, a finding specific to large-vessel and cardioembolic stroke (p = 0.001 and p = < 0.001, respectively) but not seen with small-vessel stroke (p = 0.811). Interpretation ABO gene variants are associated with large-vessel and cardioembolic stroke but not small-vessel disease. This work sheds light on the different pathogenic

    Full Text Available Clinical, neuropsychological, and neuroimaging examinations were made in 65 patients (52 men and 13 women aged 65.6±10.1 years who had experienced ischemic stroke. Cognitive impairments (CI were heterogeneous; regulatory functions, attention, and counting were most significantly affected in moderate CI. In mild dementia, mainly poor attention and regulatory dysfunctions were added by clearly-cut impairments of memory, orientation, and visual-spatial function. Brain atrophy, white matter changes, and small focal gray matter damages along with focal post-stroke changes were revealed by neuroimaging in most patients. It was found that besides the volume and location of a damage focus, the signs of impaired integrated mental activity of the brain, regulatory dysfunctions in particular, should be a necessary condition for the verification of post-stroke CI.

    Conclusions: LAA was observed frequently than SVO. Frequency of SVO was lower than Asian but higher than western, while cardio embolism was lower than Western and similar to Asian stroke studies. Dyslipidemia was the predominant risk factor than hypertension reported from Asian and Western stroke registry. This unique pattern can be attributed to differences in demographic and risk factor profiles. The study confirms the need for vigorous primary and secondary prevention measures targeting modifiable risk factors of stroke. [Int J Res Med Sci 2016; 4(11.000: 5012-5018

    Full Text Available The incidence of ischemic stroke has increased and that of hemorrhagic stroke has decreased in urban China; however, the trends in rural areas are unknown. We aimed to explore the secular trends in incidence and transition of stroke subtypes among rural Chinese.This was a population-based stroke surveillance through the Tianjin Brain Study. A total of 14,538 residents in a township of Ji County in Tianjin, China participated in the study since 1985. We investigated the age-standardized stroke incidence (sex-specific, type-specific, and age-specific, the annual proportion of change in the incidence of stroke, and the proportion of intracerebral hemorrhage in the periods 1992-1998, 1999-2005, and 2006-2012, because the neuroimaging technique was available since 1992 in this area.The age-standardized incidence per 100,000 person-years increased significantly for both intracerebral hemorrhage (37.8 in 1992-1998, 46.5 in 1999-2005, and 76.5 in 2006-2012 and ischemic stroke (83.9 in 1992-1998, 135.3 in 1999-2005, and 238.0 in 2006-2012. The age-standardized incidence of first-ever stroke increased annually by 4.9% for intracerebral hemorrhage and by 7.3% for ischemic stroke. The greatest increase was observed in men aged 45-64 years for both stroke types (P < 0.001. The proportion of intracerebral hemorrhage was stable overall, increased among men aged 45-64 years, and decreased among men aged ≥65 years. The average age of intracerebral hemorrhage in men reduced by 7.5 years from 1992 to 2012.The age-standardized incidence of main stroke subtypes increased significantly in rural China over the past 21 years; the overall proportion of intracerebral hemorrhage was stable, but the incidence increased significantly among middle-aged men. These findings imply that it is crucial to control stroke risk factors in middle-aged men for stroke prevention in future decades.

    The purpose of this study was to determine the proportion of emergency department (ED) patients with a diagnosis of peripheral vertigo who received computed tomography (CT) head imaging in the ED and to examine whether strokes were missed using CT imaging. This population-based retrospective cohort study assessed patients who were discharged from an ED in Ontario, Canada, with a diagnosis of peripheral vertigo, April 2006 to March 2011. Patients who received CT imaging (exposed) were matched by propensity score methods to patients who did not (unexposed). If performed, CT imaging was presumed to be negative for stroke because brain stem/cerebellar stroke would result in hospitalization. We compared the incidence of stroke within 30, 90, and 365 days subsequent to ED discharge between groups, to determine whether the exposed group had a higher frequency of early strokes than the matched unexposed group. Among 41 794 qualifying patients, 8596 (20.6%) received ED head CT imaging, and 99.8% of these patients were able to be matched to a control. Among exposed patients, 25 (0.29%) were hospitalized for stroke within 30 days when compared with 11 (0.13%) among matched nonexposed patients. The relative risk of a 30- and 90-day stroke among exposed versus unexposed patients was 2.27 (95% confidence interval, 1.12-4.62) and 1.94 (95% confidence interval, 1.10-3.43), respectively. There was no difference between groups at 1 year. Strokes occurred at a median of 32.0 days (interquartile range, 4.0-33.0 days) in exposed patients, compared with 105 days (interquartile range, 11.5-204.5) in unexposed patients. One fifth of patients diagnosed with peripheral vertigo in Ontario received imaging that is not recommended in guidelines, and that imaging was associated with missed strokes. © 2014 American Heart Association, Inc.

    Full Text Available Abstract Background The majority of stroke survivors have to cope with deficits in arm function, which is often measured with subjective clinical scales. The objective of this study is to examine whether circle drawing metrics are suitable objective outcome measures for measuring upper extremity function of stroke survivors. Methods Stroke survivors (n = 16 and healthy subjects (n = 20 drew circles, as big and as round as possible, above a table top. Joint angles and positions were measured. Circle area and roundness were calculated, and synergistic movement patterns were identified based on simultaneous changes of the elevation angle and elbow angle. Results Stroke survivors had statistically significant lower values for circle area, roundness and joint excursions, compared to healthy subjects. Stroke survivors moved significantly more within synergistic movement patterns, compared to healthy subjects. Strong correlations between the proximal upper extremity part of the Fugl-Meyer scale and circle area, roundness, joint excursions and the use of synergistic movement patterns were found. Conclusions The present study showed statistically significant differences in circle area, roundness and the use of synergistic movement patterns between healthy subjects and stroke survivors. These circle metrics are strongly correlated to stroke severity, as indicated by the proximal upper extremity part of the FM score. In clinical practice, circle area and roundness can give useful objective information regarding arm function of stroke survivors. In a research setting, outcome measures addressing the occurrence of synergistic movement patterns can help to increase understanding of mechanisms involved in restoration of post stroke upper extremity function.

    To determine post-stroke 30-d readmission rate, its predictors, its impact on mortality and to identify potentially preventable causes of post-stroke 30-d readmission in a population-based study. We identified all acute ischemic strokes (AIS) using the International Classification of Diseases 9th revision codes (433.x1, 434.xx and 436) via the Rochester Epidemiology Project (REP) between January 2007 and December 2011. Acute stroke care in Olmsted County is provided by two medical centers, Saint Marys Hospital and Olmsted Medical Center Hospital. All readmissions to these two hospitals were accounted for this study. Thirty-day readmission data was abstracted through manual chart review. The REP linkage database was used to identify the status (living/dead) of all patients at last follow up. Forty-one (7.6%, 95% CI 5.7%-10.2%) of total 537 AIS patients were readmitted 30-d post-stroke. In a multivariable logistic regression model, discharge to nursing home following index stroke (OR: 0.29, 95% CI 0.08-0.84) was an independent negative predictor of unplanned 30-d readmission. In a subgroup of patients with dementia, being married at time of index stroke was found to be a negative predictor of readmission (OR: 0.10, 95% CI 0.005-0.58). Only 2.8% of the patients had potentially preventable readmissions. Hospital readmission had no significant impact on patient's short-term (three months) or long-term (one or two years) mortality (p > 0.05). Post-stroke 30-d readmission rate is low in AIS patients from Olmsted County. Further research is needed in regarding discharge checklists, protocols and stroke transitional programs to reduce potentially preventable readmissions.

    Helicopters are widely used for interhospital transfers of stroke patients, but the benefit is sparsely documented. We hypothesised that helicopter transport would reduce system delay to thrombolytic treatment at the regional stroke centre. In this prospective controlled observational study, we included patients referred to a stroke centre if their ground transport time exceeded 30 min, or they were transported by a secondarily dispatched, physician-staffed helicopter. The primary endpoint was time from telephone contact to triaging neurologist to arrival in the stroke centre. Secondary endpoints included modified Rankin Scale at 3 months, 30-day and 1-year mortality. A total of 330 patients were included; 265 with ground transport and 65 with helicopter, of which 87 (33%) and 22 (34%), received thrombolysis, respectively (p=0.88). Time from contact to triaging neurologist to arrival in the regional stroke centre was significantly shorter in the ground group (55 (34-85) vs 68 (40-85) min, pground group (67 (42-136) km) than in the helicopter group (83 (46-143) km) (pground and helicopter transport. We found significantly shorter time from contact to triaging neurologist to arrival in the regional stroke centre if stroke patients were transported by primarily dispatched ground ambulance compared with a secondarily dispatched helicopter.

    Stroke is an important cause of severe disability and impaired motor function. Treatment modalities that improve motor function in patients with stroke are needed. The objective of this study was to investigate the effect of kinesthetic taping of the anterior thigh and knee on maximal walking speed and clinical indices of spasticity in patients with stroke. Thirty-two patients (9 women) receiving rehabilitation after stroke (average, 50 days since stroke) who had impaired walking ability were recruited. Primary outcome was maximal walking speed measured by the 10-meter walk test. Secondary outcomes were number of steps taken during the test and clinical signs of spasticity measured by the Tardieu Scale. Tests were conducted before and immediately after application of kinesthetic tape to the anterior thigh and knee of the paretic lower limb. After application of the tape, the maximal walking speed increased, on average, by 0.08 m/s (95% CI, 0.04 to 0.12; P stroke. Such a positive effect on motor function could be a valuable adjunct in physical therapy and rehabilitation of patients with stroke.

    Adaptive trial designs that allow enrichment of the study population through subgroup selection can increase the chance of a positive trial when there is a differential treatment effect among patient subgroups. The goal of this study is to illustrate the potential benefit of adaptive subgroup selection in endovascular stroke studies. We simulated the performance of a trial design with adaptive subgroup selection and compared it with that of a traditional design. Outcome data were based on 90-day modified Rankin Scale scores, observed in IMS III (Interventional Management of Stroke III), among patients with a vessel occlusion on baseline computed tomographic angiography (n=382). Patients were categorized based on 2 methods: (1) according to location of the arterial occlusive lesion and onset-to-randomization time and (2) according to onset-to-randomization time alone. The power to demonstrate a treatment benefit was based on 10 000 trial simulations for each design. The treatment effect was relatively homogeneous across categories when patients were categorized based on arterial occlusive lesion and time. Consequently, the adaptive design had similar power (47%) compared with the fixed trial design (45%). There was a differential treatment effect when patients were categorized based on time alone, resulting in greater power with the adaptive design (82%) than with the fixed design (57%). These simulations, based on real-world patient data, indicate that adaptive subgroup selection has merit in endovascular stroke trials as it substantially increases power when the treatment effect differs among subgroups in a predicted pattern. © 2016 American Heart Association, Inc.

    To explore and describe the caregiving experiences of Chinese stroke caregivers. Previous research has indicated that culture can have a significant impact on the stroke caregiving experience. Moreover, scant research exists on stroke caregivers' experience within the Chinese culture. A qualitative descriptive design was used. In-depth, semistructured interviews were conducted with 25 family caregivers of stroke survivors. The interviews were audiotaped, transcribed and analysed. Content analysis was also performed. Twenty-five family caregivers of stroke survivors were recruited for the study. On average, respondents were 66 years old (range 45-82 years). Of 25 interviewees, 76% were female, 64% were spouse-caregivers and 36% were children-caregivers. Three themes reflecting the influence of Chinese culture on stroke caregiving emerged from the interviews. (i) Caregiving role perception. Informants accepted caregiving for the sick family member as an expected part of life, a culturally prescribed obligation and an expression of reciprocal love. (ii) Coping strategies. Connecting with family resources and connecting with inner strength were frequently reported coping strategies. (iii) Self-sacrifice. Informants identified self-reliance and feeling of restraint in their utilisation or access of formal caregiving service. Chinese caregivers sacrifice themselves for the care recipients regardless of the hardships and the neglect of their own health. Our findings provide a comprehensive and culturally sensitive perspective in understanding the experience of stroke caregivers in Chinese communities. Cultural and religious backgrounds were found to influence Chinese stroke caregivers' experience, coping strategies and self-sacrifice behaviour in idiosyncratic ways. Research on the practice of culture can serve as a basis for the formulation of specific policies and effective interventions for supporting stroke caregivers of different cultural backgrounds. © 2017 The

    Taurine (2-aminoethanesulfonic acid), a conditionally essential sulfur-containing amino acid, is mainly obtained from diet in humans. Experimental studies have shown that taurine's main biological actions include bile salt conjugation, blood pressure regulation, anti-oxidation, and anti-inflammation. We conducted a prospective case-control study nested in the New York University Women's Health Study, a cohort study involving 14,274 women enrolled since 1985. Taurine was measured in pre-diagnostic serum samples of 241 stroke cases and 479 matched controls. There was no statistically significant association between serum taurine and stroke risk in the overall study population. The adjusted ORs for stroke were 1.0 (reference), 0.87 (95% CI, 0.59-1.28), and 1.03 (95% CI, 0.69-1.54) in increasing tertiles of taurine (64.3-126.6, 126.7-152.9, and 153.0-308.5 nmol/mL, respectively). A significant inverse association between serum taurine and stroke risk was observed among never smokers, with an adjusted OR of 0.66 (95% CI, 0.37-1.18) and 0.50 (95% CI, 0.26-0.94) for the second and third tertile, respectively (p for trend = 0.01), but not among past or current smokers (p for interaction taurine and stroke risk, although a protective effect was observed in never smokers, which requires further investigation.

    A decade ago, stroke was the first leading cause of morbidity and mortality in Croatia. Nowadays, we record reduction in stroke incidence, as well as stroke consequences-invalidity and mortality. These are due to long-term planned actions in the field of public health as well as actions performed by professional organizations. Today, we can be satisfied with improvement in that field, but there are still things we can improve, at the first place improvement of the emergency medicine network due to Croatian-specific topographical characteristics to reduce onset-to-door time. In this paper, we evaluated results from 11 Croatian hospitals in the period 11/2005-11/2012. To find out about the past and present state in applying thrombolytic therapy in Croatia and to plan further actions in light of new studies and efforts in Europe and in the world, all with the aim of improvement in stroke prevention and acute treatment resulting in reduction of stroke morbidity, mortality and symptomatic intracerebral hemorrhage as well as better functional outcome. Our results have shown that we improved stroke treatment in the last decade, but further actions should be performed to raise public stroke awareness and to improve emergency medicine network as well as in hospital protocols.

    2010-01-01

    Objective: We hypothesized that elevated plasma YKL-40 levels are associated with increased risk of ischemic cardiovascular disease in the general population. In contrast to C-reactive protein (CRP) produced in the liver in response to inflammation, YKL-40 is produced by lipid-laden macrophages...... inside the vessel wall. Methods: We measured plasma YKL-40 in 8,899 21- to 93-year-old participants of the Copenhagen City Heart Study 1991-1994 examination, and followed them for up to 18 years. Endpoints were ischemic stroke, ischemic cerebrovascular disease, myocardial infarction, and ischemic heart...

    During an outbreak of hepatitis A predominantly among men who have sex with men (MSM) in Copenhagen, Denmark, in 2004, we did a case-control study to determine risk factors for infection. A case was an MSM >17 years, living in Copenhagen, with IgM positive hepatitis A infection diagnosed between...... June and August 2004, and without a household contact with a hepatitis A case before onset of illness. Controls were selected at the Copenhagen Pride Festival. The study included 18 cases and 64 controls. Sixteen of 18 cases and 36/63 controls had sex with casual partners (ORMH 5.6, 95% CI 1.......2-26.9). Eleven of 18 cases and 14/62 controls had sex in gay saunas (ORMH 4.2, 95% CI 1.5-11.5). Sex at private homes appeared to be protective (ORMH 0.2, 95% CI 0.1-0.7). Casual sex including sex in gay saunas was an important risk factor for the spread of HAV among MSM in Copenhagen. The results...

    The objective of this study was to investigate associations between carbohydrate intake/glycemic index (GI)/glycemic load (GL) and stroke risk. A literature search of MEDLINE, Embase, Web of Science, and CBM databases was performed to retrieve eligible studies published up to March 2014. Pooled relative risks (RRs) with 95% confidence intervals (CIs) were used to evaluate the strength of this association. Publication bias was assessed by the Egger's regression asymmetry test and Begg's rank correlation test with Begg's funnel plot. All analyses were conducted using software STATA 12.0 (StataCorp LP, College Station, TX) and SAS version 9.1 (SAS Institute Inc, Cary, NC). We identified 7 prospective studies that met the inclusion criteria and processed data from cohort studies to update available evidence. There were 25 independent estimates and 225 000 participants free of diabetes from 6 different countries; 3046 stroke events were included; and the follow-up range was 5 to 18 years. High GI was not associated with risk of stroke events (pooled RR = 1.10; 95% CI: 0.99-1.21); GL was a risk factor for stroke (pooled RR = 1.19; 95% CI: 1.05-1.36). There was no significant association between high carbohydrate intake and stroke risk (RR = 1.12; 95% CI: 0.93-1.35). A daily high GL diet is the risk factor of stroke event, and further researches need to verify the meta-analyses results and study associated mechanisms.

    Though uncommon, ischaemic stroke due to temporal arteritis carries serious difficulties for diagnosis and subsequent management and requires a high level of suspicion. We analysed a series of 6 patients with biopsy-proven temporal arteritis presenting with ischaemic stroke. We discuss clinical characteristics, difficulties of assessment, short- and long-term progression, treatment, and the usefulness of new diagnostic techniques. Our sample of 6 patients had a mean age of 68.3 years; 50% were women. The majority of patients showed systemic symptoms. Anterior and posterior circulation were affected similarly. MRI angiography, Doppler sonography, and PET-CT proved to be very useful for diagnosis and treatment. Mean follow-up time was 26 months. Clinical outcomes were far from good: 33% scored≥3 on the modified Rankin scale, including one death. Two patients had recurrent stroke despite treatment with full doses of corticosteroids, and 2 underwent angioplasty. Stroke caused by giant cell arteritis is a serious and potentially severe condition which requires a high level of suspicion and early treatment with corticosteroids. New diagnostic techniques contribute to refining patient assessment and identifying the optimal treatment. Endovascular treatment may be a valid therapeutic option in selected patients.

    Stroke is a major cause of dysphagia. Few studies to date have reported on standardized multidisciplinary protocolized approaches to the management of post-stroke dysphagia. The aim of this retrospective cohort study was to evaluate the impact of a standardized multidisciplinary protocol on clinical outcomes in patients with post-stroke dysphagia. We performed retrospective chart reviews of patients with post-stroke dysphagia admitted to the neurological ward of Verona University Hospital from 2004 to 2008. Outcomes after usual treatment for dysphagia (T- group) were compared versus outcomes after treatment under a standardized diagnostic and rehabilitative multidisciplinary protocol (T+ group). Outcome measures were death, pneumonia on X-ray, need for respiratory support, and proportion of patients on tube feeding at discharge. Of the 378 patients admitted with stroke, 84 had dysphagia and were enrolled in the study. A significantly lower risk of in-hospital death (odds ratio [OR] 0.20 [0.53-0.78]), pneumonia (OR 0.33 [0.10-1.03]), need for respiratory support (OR 0.48 [0.14-1.66]), and tube feeding at discharge (OR 0.30 [0.09-0.91]) was recorded for the T+ group (N = 39) as compared to the T- group (N = 45). The adjusted OR showed no difference between the two groups for in-hospital death and tube feeding at discharge. Use of a standardized multidisciplinary protocolized approach to the management of post-stroke dysphagia may significantly reduce rates of aspiration pneumonia, in-hospital mortality, and tube feeding in dysphagic stroke survivors. Consistent with the study's exploratory purposes, our findings suggest that the multidisciplinary protocol applied in this study offers an effective model of management of post-stroke dysphagia.

    Background and Purpose Increased levels of plasma troponins and natriuretic peptides are associated with increased risk of cardiovascular disease, but only limited information exists on these biomarkers and stroke occurrence. In a prospective epidemiological study, we tested the hypothesis that high-sensitivity troponin T (TnT) and N-terminal pro B-type natriuretic peptide (NT-proBNP) are associated positively with incidence of stroke. Methods The Atherosclerosis Risk in Communities (ARIC) Study measured plasma TnT and NT-proBNP in 10,902 men or women initially free of stroke and followed them for a mean of 11.3 years for stroke occurrence (n=507). Results Both biomarkers were associated positively with total stroke, nonlacunar ischemic, and especially, cardioembolic stroke, but not with lacunar or hemorrhagic stroke. For example, after adjustment for prevalent risk factors and cardiac diseases, the hazard ratios (95% confidence intervals) for jointly high values of TnT and NT-proBNP (versus neither biomarker high) were 2.70 (1.92, 3.79) for total stroke and 6.26 (3.40, 11.5) for cardioembolic stroke. Associations with stroke appeared somewhat stronger for NT-proBNP than TnT. Strikingly, approximately 58% of cardioembolic strokes occurred in the highest quintile of pre-stroke NT-proBNP, and 32% of cardioembolic strokes occurred in participants who had both NT-proBNP in the highest quintile and were known by ARIC to have atrial fibrillation sometime before their cardioembolic stroke occurrence. Conclusions In the general population, elevated plasma TnT and NT-proBNP concentrations are associated with increased risk of cardioembolic and other nonlacunar ischemic strokes. PMID:23471272

    Industrialization including the effects of expanding energy consumption and metallurgy production as well as population growth and demographic pressure increased heavy-metal pollution loads progressively since the Industrial Revolution. Especially the burning of fossil fuels mobilizes heavy metals like lead and zinc on a large scale. By wet and dry deposition, these loads end up in the aquatic environment where sediments serve as sinks for these contaminations. In this study, we examine the pollution history of Copenhagen, Denmark. A sediment core was retrieved for the lake in the Botanical Gardens in central Copenhagen using a rod-operated piston corer. The water body used to be part of the old town's defence-wall system and was turned into a lake by terrain levelling in the mid 17th century. After initial X-ray fluorescence core scanning, element concentrations were determined using emission spectroscopy. The onset of gyttja accumulation in the lake is assumed to start immediately after the construction of the fortification in approximately AD 1645. An age model representing the last approximately 135 years for the uppermost 60cm was established by lead-210 and cesium-137 dating. The older part was dated via recognition of markedly increased levels of levoglucosan which are interpreted to be linked with recorded fires in Copenhagen. Similarly, two distinct layers interstratify the sediment column and mark pronounced increases of minerogenic material inflow which can be linked to known historical events. Significant pollution load increases are evident from the 1700s along with urban growth and extended combustion of carbon carriers fuels such as wood and coals. However, a more pronounced increase in lead and zinc deposition only begins by the mid-19th century. Maxima for the latter two pollutants are reached in the late 1970s followed by a reduction of emissions in accordance with stricter environmental regulations. Here, especially the phasing-out of tetraethyl

    Full Text Available BACKGROUND AND OBJECTIVES Stroke is a common cause of chronic debilitating disease as a result of the vascular related effect of certain part of the brain. Also the mortality due to the nature of stroke either Intracerebral Haemorrhage (ICH or Cerebral Infarction (Ischaemic stroke vary, the earlier causing more fatality. The risk factors of the ICH or the Ischaemic stroke vary to certain degree. Glycaemic state of stroke patients affects the outcome of them. It is of importance to establish clinical correlation of the glycaemic status of the stroke patients with the type and extent of the lesion documented by Computerised Tomography (CT scan of brain for development of preventive measures and clinical management of such patients for better outcome. Hence, this study was conducted among stroke patients who were admitted in Medicine wards, Jawaharlal Nehru Institute of Medical Sciences (JNIMS, Porompat, Manipur. DATA AND METHODS A study of stroke cases was undertaken in patients who were admitted to Medicine wards, Jawaharlal Nehru Institute of Medical Sciences (JNIMS, Porompat, Manipur from January 2011 till December 2014. All the patients were investigated with CT scan brain, Blood sugar along with Glycosylated Haemoglobin (HbA1C besides other routine tests and recorded. RESULT Out of the 200 stroke patients registered in 48 months, 120 patients were having hyperglycaemia. All the patients with stress hyperglycaemia were haemorrhagic. 85.71% of the cases among known diabetes were also haemorrhagic. CONCLUSION Glycaemic state of patients presented in stroke gives a picture of clinical difference. The size of the lesion measured by CT scan of brain also varies among different types of hyperglycaemia and the prognosis of the patients and showed that those patients with higher glucose level had haemorrhagic lesions with bigger size and had higher mortality rate. The deteriorating glucose tolerance with age also contributes to the increased incidence

    Left ventricular (LV) hypertrophy is associated with cardiovascular complications and the geometry is important for prognosis. In some cardiovascular diseases, myocardial hypertrophy or dilation occurs regionally without modifying the global size of the heart. It is therefore relevant to determine...... myocardial distribution (LVMD) as a measure of regional variation of the LVMT. Moreover, we wanted to determine whether these parameters varied between men and women. We studied 568 (181 men; 32%) adults, free of cardiovascular disease and risk factors, who underwent 320-detector CCTA. Mean age was 55 (range...... but different regional distribution for men and women. This study introduces LVMD and provides gender specific reference values for regional LVMT, LVMM, and LVMD....

    Full Text Available CONTEXT Stroke is the most common cause of death after cardiac disease and cancer. This study attempts to identify the significance of mean platelet volume as a risk factor as well as prognostic factor for ischemic stroke patients1 . This may help in early identification of high risk individuals who can be targeted for aggressive acute management and improved secondary prevention measures. AIM OF THE STUDY To assess whether mean platelet volume levels are elevated in ischemic stroke and to assess MPV as independent risk factor and to assess whether the severity and outcome of ischemic stroke correlates with elevated mean platelet volume. SETTINGS AND DESIGN Analytical Case Control Study. MATERIALS AND METHODS This study is conducted among 50 ischemic stroke patients who were admitted at Government Rajaji Hospital, Madurai from December 2014 to June 2015. After taking detailed history and physical examination and investigations, MPV was determined for Ischemic stroke patients and Modified Rankin scale (MRS at the time of admission was calculated. After 8 weeks of onset of stroke, all the patients were again followed up. Functional outcomes were determined by use of Modified Rankin Scale (MRS2,3. All patients were stratified using MRS2,3 Scale [0-2, 3-4 and 5-6] into three groups. MPV level was correlated with MRS score at the time of admission and again at 8 weeks. Patients with MRS score of 5 and 6 were declared as very poor outcome & MRS of 3 and 4 as poor outcome. Patients with MRS 0, and 1 were considered as good outcome. STATISTICAL ANALYSIS One way ANOVA, Pearson correlation and Chi square test. RESULTS There is no statistically significant difference among the case and control groups with regard to the age or sex composition or smoking or alcoholism. MPV did not vary with diabetes or hypertension. There was a linear relation with MPV and severity of ischemic stroke i.e. as the MPV increases the severity (MRS 2,3of stroke increases

    Deep-vein thrombosis (DVT) represents a serious complication in acute stroke patients with pulmonary embolus (PE) as a potential outcome. Prediction of DVT may help with formulating a proper prevention strategy. To assess of the risk of deep venous thrombosis (DVT) in acute stroke patients, we developed and validated a clinical score in a cohort study. Incidence of Deep Venous Thrombosis after Acute Stroke in China (INVENT-China) is a multicenter prospective cohort study. The potential predictive variables for DVT at baseline were collected, and the presence of DVT was evaluated using ultrasonography on the 14 ± 3 days. Data were randomly assigned to either a training data set or a test data set. Multivariate logistic regression analysis was used to develop risk scores to predict DVT in the training data set and the area under the receiver operating characteristic curve to validate the score in the test data set. From 2006-2007, 862 hospital-based acute stroke patients were enrolled in China. The overall incidence of DVT after acute stroke within two weeks was 12.4% (95%CI 10.3-14.7%). A seven-point score derived in the training data set (age [≥65 years = 1], sex [female gender = 1]), obesity [BMI ≥ 25 kg/m(2) = 1], active cancer [yes = 2], stroke subtype [cerebral hemorraghe = 1], muscle weakness [≥2 on Lower limb NIHSS score = 1] was highly predictive of 14-day risk of DVT(c statistic = 0.70, 95% CI, 0.64-0.76, P < 0.001), in the overall study population(c statistic = 0.65, 95% CI 0.59-0.70, P < 0.001). This clinical score may help identify acute stroke patients with high risk of DVT. In addition, it also serves as a platform to develop further models of DVT prediction in stroke patients based on clinical factors. © 2014 John Wiley & Sons Ltd.

  2. Fatal stroke after the death of a sibling: a nationwide follow-up study from Sweden.

    Full Text Available BACKGROUND: Although less studied than other types of familial losses, the loss of a sibling could be a potential trigger of stroke as it represents a stressful life event. We studied the association between loss of a sibling and fatal stroke up to 18 years since bereavement. METHODOLOGY/PRINCIPAL FINDINGS: We conducted a follow-up study between 1981 and 2002, based on register data covering the total population of Swedes aged 40-69 years (n = 1,617,010. An increased risk of fatal stroke (1.31 CI: 1.05, 1.62 was found among women who had experienced the loss of a sibling. No increase in the overall mortality risk was found in men (1.11 CI: 0.92, 1.33. An elevated risk in the short term (during the second and third half-year after the death was found among both men and women, whereas longer-term elevation in risk was found primarily for women. Both external (1.47 CI: 1.00, 2.17 and not external (1.26 CI: 1.00, 1.60 causes of sibling death showed associations among women. In men, an association was found only if the sibling also died from stroke (1.78 CI: 1.00, 3.17. However, among women, we found an increased risk of stroke mortality if the sibling died from causes other than stroke (1.30 CI: 1.04, 1.62. CONCLUSIONS/SIGNIFICANCE: The findings suggest an increased risk of dying from stroke mortality after the death of a sibling, and that bereavement affects particularly women. It is important for health care workers to follow bereaved siblings and recognize potential changes of stress-levels and health related behaviours that could lead to risk of stroke.

    The multicenter prospective study of cerebrolysin safety and efficacy included 277 patients with ischemic stroke aged 55-85 years, who received therapy within 12 h from the disease development. Cerebrolysin was used in dosage 10 ml daily along with concomitant standard basic treatment during 10 days after stroke onset in 138 patients. A control group comprised 139 patients who received basic treatment only. A quantitative analysis of the dynamics of neurological deficit revealed the accelerated improvement by NIHSS score, modified Rankin score and Barthel index in the cerebrolysin group on days 10 and 28 (pcerebrolysin within the first 3h after stroke onset comparing to those treated within 6-12h. The trial demonstrated cerebrolysin safety and good tolerability in treatment of ischemic stroke in the carotid artery territory as well as its favorable clinical effect.

    In order to explore the ways to prevent from the disease, 4,793 subjects aged over 40 at high risk of stroke from a total population of 250,000 in communities with high incidence of it were studied with multiple factor intervention, by oral administration of "Nao An" capsules as a major measure in 10 areas of north and northeast China, as well as Shanghai, during 1990 to 1993. Three years after intervention, incidence of stroke decreased by 49.17% in the population, with reduction of systolic and diastolic blood pressure, levels of blood sugar, cholesterol and triglyceride. Lowering of stroke incidence correlated positively with that of blood pressure in the population. It suggests stroke can be prevented effectively by concentrated efforts in comprehensive intervention in individuals at high risk.

    Left ventricular (LV) hypertrophy is associated with cardiovascular complications and the geometry is important for prognosis. In some cardiovascular diseases, myocardial hypertrophy or dilation occurs regionally without modifying the global size of the heart. It is therefore relevant to determine regional normal reference values of the left ventricle. The aim of this study was to derive reference values of regional LV myocardial thickness (LVMT) and mass (LVMM) from a healthy study group of the general population using cardiac computed tomography angiography (CCTA). We wanted to introduce LV myocardial distribution (LVMD) as a measure of regional variation of the LVMT. Moreover, we wanted to determine whether these parameters varied between men and women. We studied 568 (181 men; 32%) adults, free of cardiovascular disease and risk factors, who underwent 320-detector CCTA. Mean age was 55 (range 40-84) years. Regional LVMT and LVMM were measured, according to the American Heart Association's 17 segment model, using semi-automatic software. Mean LVMT were 6.6 mm for men and 5.4 mm for women (p normal LV was thickest in the basal septum (segment 3; men = 8.3 mm; women = 7.2 mm) and thinnest in the mid-ventricular anterior wall (segment 7; men = 5.6 mm; women = 4.5 mm) for both men and women. However, the regional LVMD differed between men and women, with the LV being most heterogenic in women. The normal human LV is morphologically heterogenic, and showed same overall pattern but different regional distribution for men and women. This study introduces LVMD and provides gender specific reference values for regional LVMT, LVMM, and LVMD.

    Full Text Available Objectives: This study aimed to investigate the long-term risk of stroke in adult patients with spinal deformity. Specifically, the study addressed the possible protective effect of surgery for spinal deformity against stroke. Methods: Using the National Health Insurance Research Database (NHIRD, a monopolistic national database in Taiwan, this retrospective cohort study analyzed the incidence of stroke in patients with adult spinal deformity (ASD in a 11-year period. A total of 13,503 patients, between 55 and 75 years old, were identified for the diagnosis of ASD. The patients were grouped into two: the surgical group (n = 10,439 who received spinal fusion surgery, and the control group (n = 2124 who received other medical treatment. The incidence rates of all subsequent cerebrovascular accidents, including ischemic and hemorrhagic strokes, were calculated. Hazard ratios for stroke were calculated use a full cohort and a propensity score matched cohort. Adjustments for co-morbidities that may predispose to stroke, including hypertension, diabetes mellitus, arrhythmia and coronary heart disease were conducted. Kaplan-Meier and Cox regression analyses were performed to compare the risk of stroke between the two groups. Results: During the total observation period of 50,450 person-years, the incidence rate of stroke in the surgical group (15.55 per 1000 person-years was significantly lower than that of the control group (20.89 per 1000 person-years, p < 0.001. Stroke was more likely to occur in the control group than in the surgical group (crude hazard ratio 1.34, p < 0.001; adjusted HR 1.28, p < 0.001, by a propensity score matched model. Conclusions: In this national cohort of more than 13,000 ASD patients covering 10 years, stroke was approximately 25% less likely to happen in patients who underwent spinal fusion surgery than those who received medical management. Therefore, spinal fusion surgery may provide a protective effect against stroke

  12. The Emergent Copenhagen Interpretation of Quantum Mechanics

    CERN Document Server

    Hollowood, Timothy J

    2013-01-01

    We introduce a new and conceptually simple interpretation of quantum mechanics based on reduced density matrices of sub-systems from which the standard Copenhagen interpretation emerges as an effective description of macroscopically large systems. Wave function collapse is seen to be a useful but fundamentally unnecessary piece of prudent book keeping which is only valid for macro-systems. The new interpretation lies in a class of modal interpretations in that it applies to quantum systems that interact with a much larger environment. However, we show that it does not suffer from the problems that have plagued similar modal interpretations like macroscopic superpositions and rapid flipping between macroscopically distinct states. We describe how the interpretation fits neatly together with fully quantum formulations of statistical mechanics and that a measurement process can be viewed as a process of ergodicity breaking analogous to a phase transition. The key feature of the new interpretation is that joint p...

  14. Geriatric rehabilitation of stroke patients in nursing homes: a study protocol

    Directory of Open Access Journals (Sweden)

    Geurts Alexander CH

    2010-03-01

    Full Text Available Abstract Background Geriatric patients are typically underrepresented in studies on the functional outcome of rehabilitation after stroke. Moreover, most geriatric stroke patients do probably not participate in intensive rehabilitation programs as offered by rehabilitation centers. As a result, very few studies have described the successfulness of geriatric stroke rehabilitation in nursing home patients, although it appears that the majority of these patients are being discharged back to the community, rather than being transferred to residential care. Nevertheless, factors associated with the successfulness of stroke rehabilitation in nursing homes or skilled nursing facilities are largely unknown. The primary goal of this study is, therefore, to assess the factors that uniquely contribute to the successfulness of rehabilitation in geriatric stroke patients that undergo rehabilitation in nursing homes. A secondary goal is to investigate whether these factors are similar to those associated with the outcome of stroke rehabilitation in the literature. Methods/Design This study is part of the Geriatric Rehabilitation in AMPutation and Stroke (GRAMPS study in the Netherlands. It is a longitudinal, observational, multicenter study in 15 nursing homes in the Southern part of the Netherlands that aims to include at least 200 patients. All participating nursing homes are selected based on the existence of a specialized rehabilitation unit and the provision of dedicated multidisciplinary care. Patient characteristics, disease characteristics, functional status, cognition, behavior, and caregiver information, are collected within two weeks after admission to the nursing home. The first follow-up is at discharge from the nursing home or one year after inclusion, and focuses on functional status and behavior. Successful rehabilitation is defined as discharge from the nursing home to an independent living situation within one year after admission. The

    Thiazolidinediones (TZDs) - rosiglitazone and pioglitazone - a class of insulin sensitizer for treating type 2 diabetes, have been reported to exhibit neuroprotective effects in preclinical studies and have good effects in the control of blood sugar for diabetic patients with insulin resistance. However, clinical trials and observational studies have raised the possibility of higher stroke risk in patients treated with rosiglitazone. Whether pioglitazone poses similar stroke risk remains uncertain. Most of the studies on cardiovascular effects of TZDs were based on studies in the USA and Europe. The present study aimed to compare the stroke risk among diabetic patients on TZD to those on non-TZD medications in an Asian population. The study cohort included 15,981 patients with a diagnosis of diabetes without prior stroke, acute myocardial infarction (AMI) or heart failure who were followed from 2001 to 2010. Patients were classified by their prescriptions into rosiglitazone, pioglitazone and non-TZD groups. The study end points included ischemic and hemorrhagic stroke. In view of the reported association of heart failure and AMI with rosiglitazone, these 2 end points were also included in the present study. Cox hazard proportional models were used to estimate the risk of developing the end points. Likelihood ratio test was used to examine the age-drug interactions. Dose-response effects were evaluated by comparing the incidence rates among patients with different cumulative exposures to TZD. During the 10-year follow-up, the rosiglitazone group showed significantly higher risk of ischemic stroke (multivariate adjusted hazard ratio, HR = 1.39; 95% confidence interval, CI = 1.16-1.66) and heart failure (HR = 1.59; 95% CI = 1.18-2.14) than the non-TZD group. The pioglitazone group did not show significant difference from the non-TZD group in ischemic stroke (HR = 0.97; 95% CI = 0.75-1.26) and heart failure (HR = 0.94; 95% CI = 0.59-1.50). The results also showed a

    Caregivers of stroke survivors experience high rates of mental and physical morbidity. Stroke has sudden onset, and the outcome is not immediately known. Uncertainties surrounding the new caregiving role may not only necessitate major changes in the lives of family caregivers but also contribute to negative health outcomes for the caregiver. The purposes of this study were to describe caregiver uncertainty across the early weeks after a family member's stroke and to explore characteristics of caregivers and stroke survivors associated with that uncertainty. A prospective, longitudinal exploratory observational study was conducted with a convenience sample of 40 caregivers and older adult (≥65 years) stroke survivors recruited from urban acute care settings in the mid-Atlantic region. Caregivers were enrolled by 2 weeks poststroke (T1) and revisited 4 weeks later (T2). Uncertainty was measured usingthe Mishel Uncertainty in Illness Scale for Family Members. An unadjusted linear mixed model was computed to examine significant associations between each caregiver or stroke survivor characteristic and repeated measures of uncertainty. Uncertainty at T1 (83.73 ± 23.47) was higher than reported in other caregiver populations and remained high 6 weeks poststroke (T2: 85.23 ± 23.94). Each of the following characteristics was independently associated with greater caregiver uncertainty: caregivers' older age (p = .019), being a spouse (p = .01), higher stress (p stroke survivors' recurrent stroke (p = .034), poorer functional status (p = .009), and insurance type (p = .008). Caregivers experienced persistently high uncertainty during the first 6 weeks poststroke. Better understanding of uncertainty, its associated characteristics, and its outcomes may help clinicians identify caregivers at highest risk who may benefit from targeted interventions.

    Full Text Available The associations between phosphate, calcium, and intact parathyroid hormone (PTH levels and composite cardiovascular end points have been studied. This study examined the associations of these markers with myocardial infarction (MI and stroke separately.This is a longitudinal study on 65,849 hemodialysis patients from the Japan Renal Data Registry. Patients with prior events at baseline were excluded. Predictors were phosphate, albumin-corrected calcium, intact PTH, and calcium times phosphate product levels. Outcome was the first episode of MI or stroke during a 1-year observation period. Data were analyzed using multiple logistic regression analyses, adjusted for potential confounders.There were 1,048, 651, and 2,089 events of incident MI, hemorrhagic, and ischemic stroke, respectively. Incident MI was associated with phosphate levels ≥6.5 mg/dL (odds ratio 1.49; confidence interval 1.23-1.80 compared with phosphate levels of 4.7-5.4 mg/dL and intact PTH levels>500 pg/mL (1.35; 1.03-1.79 compared with intact PTH levels of 151-300 pg/mL. Higher albumin-corrected calcium level was positively associated with MI (p = 0.04 by trend analysis. Hemorrhagic stroke was associated only with intact PTH levels>500 pg/mL (1.54; 1.10-2.17. Incident ischemic stroke had no association with phosphate, calcium, or intact PTH levels. The association of calcium times phosphate product with outcomes was essentially the same pattern as that of phosphate and outcomes.MI was associated with phosphate, calcium, and intact PTH levels, whereas hemorrhagic stroke was associated only with intact PTH. Ischemic stroke was not associated with any of them. The potential distinct beneficial effect on MI and stroke by managing bone and mineral disease should be investigated in future studies.

  3. Secret letters cast light on Copenhagen

    Letters by Niels Bohr that have been kept secret since his death could explain the mystery of why Werner Heisenberg visited him in Copenhagen in 1941. When the author Michael Frayn spent two years writing Copenhagen, he had no idea how successful the play would become. He doubted that audiences would sit through a historical drama about a war-time meeting between Werner Heisenberg - head of Germany's nuclear programme - and his old mentor Niels Bohr in the Nazi-occupied Danish capital in 1941. But Frayn's efforts paid off. Audiences and critics alike have thrilled at the way the award-winning play probes the historical uncertainty that surrounds the encounter. Was Heisenberg fishing for information about the Allies' atomic plans - or was he trying to recruit Bohr for Germany's bomb programme? Did Heisenberg want to suggest that the Germans were close to finishing a bomb so that the Allies would make peace with Hitler? Maybe he was simply seeking approval from Bohr for his own atomic work. There is also a moral debate: did Heisenberg know how to build a bomb, but decided not to - or did he want to build one, but got his calculations wrong? Unfortunately, no-one was there to record or observe the encounter and we cannot know for sure what was said or implied between the two men. All we do know is that the pair dined together and took a short walk - and that the incident damaged Bohr and Heisenberg's friendship forever. To piece together what happened, historians of science have had to rely on Heisenberg's post-war recollections - which have been ambiguous and contradictory - along with scraps of evidence from secondary sources.

    Rationale Prehospital stroke care in specialized ambulances increases thrombolysis rates, reduces alarm-to-treatment times, and improves the prehospital triage. Preliminary analyses suggest cost-effectiveness. However, scientific proof of better functional outcome compared to usual care is still lacking. Aim To prove better functional outcomes after deployment of the Stroke Emergency Mobile compared to regular ambulances. Sample size estimates A sample size of 686 patients will be required in each arm (Stroke Emergency Mobile group vs. regular care) to detect a difference regarding the primary outcome with 80% power at a two-sided significance level of 0.05. Methods and design This is a pragmatic, prospective study with blinded outcome assessment. Primary outcome will be functional status as defined by modified Rankin Scale score three months after the incident event. We will include cerebral ischemia patients within a predefined catchment area in Berlin, Germany. The study population consists of patients who might be candidates for acute recanalizing treatments, with onset-to-alarm time ≤4 h, symptoms not resolved at time of ambulance arrival, and able to walk without assistance prior to the qualifying incident. About 45% of Stroke Emergency Mobile dispatches are expected to be handled by regular ambulances, since Stroke Emergency Mobile will be already in operation creating the control group. Primary outcome Functional outcome after three months measured by the modified Rankin Scale over the entire range. Discussion The results will inform decision makers on the effectiveness of Stroke Emergency Mobile.

    Full Text Available Abstract Background Strokes are a common cause of adult disability and mortality worldwide. Transient ischaemic attacks (TIA are associated with a high risk of subsequent stroke, and rapid intervention has the potential to reduce stroke burden. This study will assess a novel electronic decision support (EDS tool to allow general practitioners (GPs to implement evidence-based care rapidly without full reliance on specialists. Methods/design This is a cluster randomized controlled trial comparing TIA/stroke management of GPs with access to the EDS tool versus usual care. The intervention period is 12 months with a 3-month follow-up period for individual patients. Primary outcomes consist of stroke within 90 days of presenting event and adherence to the New Zealand national TIA guideline. Discussion A positive study will provide strong evidence for widespread implementation of this tool in practice and has the potential to improve key outcomes for patients and reduce the burden of stroke.

    Background Incontinence is a common problem faced by family caregivers that is recognized as a major burden and predictor of institutionalization. However, few studies have evaluated the experiences of family caregivers caring for stroke survivors with incontinence. Purpose To describe experiences of caregivers managing incontinence in stroke survivors. Design This qualitative descriptive study employed a grounded-theory approach. Methods Semi-structured in-depth interviews with ten family caregivers of stroke survivors with incontinence were conducted during 2011. Audiotaped interviews were transcribed and analyzed using content analysis. Findings Data analysis identified four themes: chaos, hypervigilance, exhaustion, and creating a new life. There were nine related subcategories: fluster, dirtiness, urgency, fear of potential health-hazard, physically demanding and time-consuming, mentally draining, financial burden, learning by doing, and attitude adjustment. Together, these described a process of struggling to cope with the care of stroke survivors with urinary/fecal incontinence. Of the four categories, “creating a new life” developed gradually over time to orient caregivers to their new life, while the other three categories occurred in a chronological order. Conclusion The research highlighted unique caring experiences of family caregivers of stroke patients, which focused solely on the ‘incontinence issue’. Understanding these experiences may help nurses provide better support and resources for family caregivers when caring for stroke survivors with incontinence. PMID:26066345

    In a new approach the odour emissions from aircraft engines at Copenhagen Airport are calculated using actual fuel flow and emission measurements (one main engine and one APU: Auxiliary Power Unit), odour panel results, engine specific data and aircraft operational data for seven busy days. The calculation principle assumes a linear relation between odour and HC emissions. Using a digitalisation of the aircraft movements in the airport area, the results are depicted on grid maps, clearly reflecting aircraft operational statistics as single flights or total activity during a whole day. The results clearly reflect the short-term temporal fluctuations of the emissions of odour (and exhaust gases). Aircraft operating at low engine thrust (taxiing, queuing and landing) have a total odour emission share of almost 98%, whereas the shares for the take off/climb out phases (2%) and APU usage (0.5%) are only marginal. In most hours of the day, the largest odour emissions occur, when the total amount of fuel burned during idle is high. However, significantly higher HC emissions for one specific engine cause considerable amounts of odour emissions during limited time periods. The experimentally derived odour emission factor of 57 OU/mg HC is within the range of 23 and 110 OU/mg HC used in other airport odour studies. The distribution of odour emission results between aircraft operational phases also correspond very well with the results for these other studies. The present study uses measurement data for a representative engine. However, the uncertainties become large when the experimental data is used to estimate the odour emissions for all aircraft engines. More experimental data is needed to increase inventory accuracy, and in terms of completeness it is recommended to make odour emission estimates also for engine start and the fuelling of aircraft at Copenhagen Airport in the future.

    2005-04-01

    The associations between physical activity in leisure time with special focus on jogging and the level of mental stress and life dissatisfaction were studied in 12 028 randomly selected men and women aged 20-79 years. The associations were similar in men and women; thus, results are given for pooled data. The odds ratios (ORs) are presented as adjusted for sex, age, body mass index, smoking, alcohol consumption, education and income. With increasing physical activity in leisure time, there was a decrease in high level of stress, between sedentary persons and joggers, OR=0.30 (95% confidence interval (CI) from 0.16 to 0.56). With increasing physical activity there was also a decrease in life dissatisfaction, between sedentary persons and joggers, OR=0.30 (95% CI from 0.18 to 0.52). Although there was a dose-response effect between physical activity and psychosocial well-being the most pronounced difference with regard to the level of stress and dissatisfaction was seen between the group with low and the group with moderate physical activity, e.g., 2-4 h of walking per week. In conclusion, we recommend that increased well-being should be a key argument in future campaigns for increased leisure-time physical activity.

    OBJECTIVE: Long-term exposure to occupational noise may be associated with an increased risk of ischemic heart disease (IHD) and all-cause mortality. However, the issue remains unsettled. Only a small number of longitudinal studies have been carried out, and control for potential confounders...... including a strong correlate of noise exposure namely social class may have been insufficient. METHODS: We carried out a 16-year follow-up of 2998 men aged 53-75 years without overt cardiovascular disease. RESULT: Overall, 197 men (6.6%) died due to IHD and 1192 (39.8%) from all-causes. Of the 2998 men......, 1008 (33.6%) reported exposure to occupational noise for ≥5 years [mean 25.4, standard deviation (SD) 12.5 years]; among these men, 47.3% reported hearing impairment versus only 24.8% among unexposed men (63.0%). Referencing unexposed men, the hazard ratio (HR) for IHD mortality was 0.97 [95...

    Full Text Available The large eddy simulations employing the SUBMESO model with the urban soil layer model SM2-U were performed for the model domain covering the Danish Island of Sealand and including the Copenhagen metropolitan area. Monthly and diurnal cycle variability were studied for the net radiation, sensible and storage heat fluxes, surface's temperatures, and others. These were evaluated for selected urban vs. non urban related types of covers/surfaces and urban districts such as city center, high buildings, industrial, and residential. Results showed strong effects of urban features on temporal and spatial variability. They are useful and applicable for verification of numerical weather prediction models and development of urban canopy parameterizations.

    The Copenhagen Accord has been followed up by national pledges of greenhouse gas emissions reductions in the year 2020 without specifying measures to enforce actions. As a consequence, the capacity of parties to fulfil their obligations is of basic interest. This article outlines the effects of full compliance with pledges on greenhouse gas emissions, economic growth, and trade. The study is based on the global computable general equilibrium model GRACE distinguishing between fossil and non-fossil energy use. Global emissions from fossil fuels in 2020 turn out to be 15% lower than in a business as usual (BAU) scenario and 3% below the global emissions from fossil fuels in 2005. China and India increase their emissions in 2020 to 1 and 5 per cent above BAU levels in 2020, respectively. We find some carbon leakage towards India, China and Russia within the energy intensive industries steel and cement.(auth)

    Chronic inflammation plays an important role in schizophrenia and atopic diseases, and studies have suggested that chronic inflammation is associated with an increased risk of stroke. The role of atopic diseases in the development of stroke among patients with schizophrenia is still unknown. A total of 63,913 patients with schizophrenia without a stroke history between 2002 and 2008 and 63,913 age- and sex-matched controls were included and followed up to the end of 2011. Patients with schizophrenia and the reference group were divided into subgroups based on the presence or absence of atopic diseases. Individuals who developed stroke during follow-up were identified. Patients with schizophrenia had an increased risk of developing ischemic stroke (no atopic disease: hazard ratio [HR] = 2.18, 95% confidence interval [CI] = 1.88-2.53; with atopic disease: HR = 3.11, 95% CI = 2.63-3.69) compared with the reference group without atopic diseases. Among patients with schizophrenia, the presence of atopic diseases increased the risk of developing ischemic stroke (HR = 1.44, 95% CI = 1.24-1.66), with a cumulative relationship between greater numbers of atopic comorbidities and a greater risk of ischemic stroke (one atopic disease: HR = 1.39, 95% CI = 1.19-1.63; two atopic comorbidities: HR = 1.48, 95% CI = 1.10-2.00; at least 3 atopic comorbidities: HR = 2.81, 95% CI = 1.55-5.12). The combined presence of schizophrenia and atopic diseases is associated with an increased risk of ischemic stroke in later life compared with individuals without these conditions.

    Coffee consumption has been inconsistently associated with risk of stroke. The authors conducted a meta-analysis of prospective studies to quantitatively assess the association between coffee consumption and stroke risk. Pertinent studies were identified by searching PubMed and Embase from January 1966 through May 2011 and by reviewing the reference lists of retrieved articles. Prospective studies in which investigators reported relative risks of stroke for 3 or more categories of coffee consumption were eligible. Results from individual studies were pooled using a random-effects model. Eleven prospective studies, with 10,003 cases of stroke and 479,689 participants, met the inclusion criteria. There was some evidence of a nonlinear association between coffee consumption and risk of stroke (P for nonlinearity = 0.005). Compared with no coffee consumption, the relative risks of stroke were 0.86 (95% confidence interval (95% CI): 0.78, 0.94) for 2 cups of coffee per day, 0.83 (95% CI: 0.74, 0.92) for 3-4 cups/day, 0.87 (95% CI: 0.77, 0.97) for 6 cups/day, and 0.93 (95% CI: 0.79, 1.08) for 8 cups/day. There was marginal between-study heterogeneity among study-specific trends (I₂ = 12% and I₂ = 20% for the first and second spline transformations, respectively). Findings from this meta-analysis indicate that moderate coffee consumption may be weakly inversely associated with risk of stroke.

    Characters, which are man-made symbols composed of strokes arranged in a certain structure, could provide semantic information and play an indispensable role in our daily life. In this paper, we try to make use of the intrinsic characteristics of characters and explore the stroke and structure-based methods for character recognition. First, we introduce two existing part-based models to recognize characters by detecting the elastic strokelike parts. In order to utilize strokes of various scales, we propose to learn the discriminative multi-scale stroke detector-based representation (DMSDR) for characters. However, the part-based models and DMSDR need to manually label the parts or key points for training. In order to learn the discriminative stroke detectors automatically, we further propose the discriminative spatiality embedded dictionary learning-based representation (DSEDR) for character recognition. We make a comparative study of the performance of the tree-structured model (TSM), mixtures-of-parts TSM, DMSDR, and DSEDR for character recognition on three challenging scene character recognition (SCR) data sets as well as two handwritten digits recognition data sets. A series of experiments is done on these data sets with various experimental setup. The experimental results demonstrate the suitability of stroke detector-based models for recognizing characters with deformations and distortions, especially in the case of limited training samples.

    There is considerable controversy about the causes of cognitive decline after stroke, with evidence for both the absence and coexistence of Alzheimer pathology. A reduction in cortical thickness has been shown to be an important biomarker for the progression of many neurodegenerative diseases, including Alzheimer's disease (AD). However, brain volume changes following stroke are not well described. Cortical thickness estimation presents an ideal way to detect regional and global post-stroke brain atrophy. In this study, we imaged a group of patients in the first month after stroke and at 3 months. We compared three methods of estimating cortical thickness on unmasked images: one surface-based (FreeSurfer) and two voxel-based methods (a Laplacian method and a registration method, DiRecT). We used three benchmarks for our analyses: accuracy of segmentation (especially peri-lesional performance), reproducibility, and biological validity. We found important differences between these methods in cortical thickness values and performance in high curvature areas and peri-lesional regions, but similar reproducibility metrics. FreeSurfer had less reliance on manual boundary correction than the other two methods, while reproducibility was highest in the Laplacian method. A discussion of the caveats for each method and recommendations for use in a stroke population is included. We conclude that both surface- and voxel-based methods are valid for estimating cortical thickness in stroke populations.

    Full Text Available Although motor imagery could improve motor rehabilitation, the detailed neural mechanisms of motor imagery cognitive process of stroke patients, particularly from functional network perspective, remain unclear. This study investigated functional brain network properties in each cognitive sub-stage of motor imagery of stroke patients with ischemic lesion in left hemisphere to reveal the impact of stroke on the cognition of motor imagery. Both stroke patients and control subjects participated in mental rotation task, which includes three cognitive sub-stages: visual stimulus perception, mental rotation and response cognitive process. Event-related electroencephalograph was recorded and interdependence between two different cortical areas was assessed by phase synchronization. Both global and nodal properties of functional networks in three sub-stages were statistically analyzed. Phase synchronization of stroke patients significantly reduced in mental rotation sub-stage. Longer characteristic path length and smaller global clustering coefficient of functional network were observed in patients in mental rotation sub-stage which implied the impaired segregation and integration. Larger nodal clustering coefficient and betweenness in contralesional occipitoparietal and frontal area respectively were observed in patients in all sub-stages. In addition, patients also showed smaller betweenness in ipsilesional central-parietal area in response sub-stage. The compensatory effects on local connectedness and centrality indicated the neuroplasticity in contralesional hemisphere. The functional brain networks of stroke patients demonstrated significant alterations and compensatory effects during motor imagery.

    To follow up an original research project of persons 11-13 years after stroke, in order to describe and understand the impact of stroke on everyday life experienced during these years. Eleven persons who had had a stroke were interviewed 11-13 years after the original research project. Data were collected and analysed using the empirical phenomenological psychological method. Three main characteristics were identified from analysis of participants' experiences during the years after stroke: () going through the loss of the previous life; () struggling to reclaim the former existence; () finding meaning in a "new" and different world. This study provides an understanding of the complexity of the lost connection between body and world occurring for a long time after stroke. This understanding provides support for the need for long-term and intermittent support and guidance to enable the re-creation of meaning and participation in everyday life in order to find a "new" self-identity after stroke, especially among persons with residual cognitive impairment.

    The Copenhagen interpretation is critically considered. A number of ambiguities, inconsistencies and confusions are discussed. It is argued that it is possible to purge the interpretation so as to obtain a consistent and reasonable way to interpret the mathematical formalism of quantum mechanics, which is in agreement with the way this theory is dealt with in experimental practice. In particular, the essential role attributed by the Copenhagen interpretation to measurement is acknowledged. For this reason it is proposed to refer to it as a neo-Copenhagen interpretation.

    Full Text Available Background: Insomnia symptoms are common in the population and have negative psychosocial and functional sequelae. There are no prospective studies of the course of such symptoms and their impact, if any, in stroke survivors. This prospective cohort study investigated insomnia after stroke in working-age adults and evaluated its impact on psychological and functional outcomes over the subsequent year. Methods: We prospectively recruited 441 young (<65 years consecutive stroke survivors from 20 public hospitals in the New South Wales Stroke Service network. Participants were assessed by self-report and interview at 28 days, 6 months, and 12 months after stroke. Insomnia was defined using a common epidemiological measure of sleep disturbance and daytime consequences. Depression, anxiety, disability, and return to work were assessed through standardized measures. Results: The point prevalence of insomnia at each time point in the year after stroke was stable at 30–37% and more common in females. Fifty-eight (16% of all participants reported “chronic” insomnia, with symptoms at both baseline and 6 months later. At 12 months, this group was more likely to be depressed (OR 6.75, 95% CI 2.78–16.4, anxious (OR 3.31, 95% CI 1.54–7.09, disabled (OR 3.60, 95% CI 2.07–6.25, and not have returned to work, compared to those without insomnia over the same period. Conclusions: Chronic insomnia has a negative effect on disability and return to work 1 year after stroke even after adjusting for demographic, psychiatric, and disability factors. Identifying and appropriately targeting insomnia through known effective treatments may improve functional outcomes after stroke.

    Background and Purpose Although the prothrombin G20210A mutation has been implicated as a risk factor for venous thrombosis, its role in arterial ischemic stroke is unclear, particularly among young-adults. To address this issue, we examined the association between prothrombin G20210A and ischemic stroke in a Caucasian case-control population and additionally performed a meta-analysis Methods From the population-based Genetics of Early Onset Stroke (GEOS) study we identified 397 individuals of European ancestry aged 15-49 years with first-ever ischemic stroke and 426 matched-controls. Logistic regression was used to calculate odds ratios in the entire population and for subgroups stratified by gender, age, oral contraceptive use, migraine and smoking status. A meta-analysis of 17 case-control studies (n=2305 cases stroke did not achieve statistical significance (OR=2.5,95%CI=0.9-6.5,p=0.07). However, among adults aged 15-42 (younger than median age), cases were significantly more likely than controls to have the mutation (OR=5.9,95%CI=1.2-28.1,p=0.03), whereas adults ages 42-49 were not (OR=1.4,95%CI=0.4-5.1,p=0.94). In our meta-analysis, the mutation was associated with significantly increased stroke risk in adults stroke in young-adults and may have an even stronger association among those with earlier onset strokes. Our finding of a stronger association in the younger-young adult population requires replication. PMID:24619398

    Stroke significantly affects thousands of individuals annually, leading to considerable physical impairment and functional disability. Gait is one of the most important activities of daily living affected in stroke survivors. Recent technological developments in powered robotics exoskeletons can create powerful adjunctive tools for rehabilitation and potentially accelerate functional recovery. Here, we present the development and evaluation of a novel lower limb robotic exoskeleton, namely H2 (Technaid S.L., Spain), for gait rehabilitation in stroke survivors. H2 has six actuated joints and is designed to allow intensive overground gait training. An assistive gait control algorithm was developed to create a force field along a desired trajectory, only applying torque when patients deviate from the prescribed movement pattern. The device was evaluated in 3 hemiparetic stroke patients across 4 weeks of training per individual (approximately 12 sessions). The study was approved by the Institutional Review Board at the University of Houston. The main objective of this initial pre-clinical study was to evaluate the safety and usability of the exoskeleton. A Likert scale was used to measure patient's perception about the easy of use of the device. Three stroke patients completed the study. The training was well tolerated and no adverse events occurred. Early findings demonstrate that H2 appears to be safe and easy to use in the participants of this study. The overground training environment employed as a means to enhance active patient engagement proved to be challenging and exciting for patients. These results are promising and encourage future rehabilitation training with a larger cohort of patients. The developed exoskeleton enables longitudinal overground training of walking in hemiparetic patients after stroke. The system is robust and safe when applied to assist a stroke patient performing an overground walking task. Such device opens the opportunity to study means

    To report and synthesize the perspectives, experiences, and preferences of stroke survivors undertaking inpatient physical rehabilitation through a systematic review of qualitative studies. MEDLINE, CINAHL, Embase, and PsycINFO were searched from database inception to February 2014. Reference lists of relevant publications were searched. All languages were included. Qualitative studies reporting stroke survivors' experiences of inpatient stroke rehabilitation were selected independently by 2 reviewers. The search yielded 3039 records; 95 full-text publications were assessed for eligibility, and 32 documents (31 studies) were finally included. Comprehensiveness and explicit reporting were assessed independently by 2 reviewers using the consolidated criteria for reporting qualitative research framework. Discrepancies were resolved by consensus. Data regarding characteristics of the included studies were extracted by 1 reviewer, tabled, and checked for accuracy by another reviewer. All text reported in studies' results sections were entered into qualitative data management software for analysis. Extracted texts were inductively coded and analyzed in 3 phases using thematic synthesis. Nine interrelated analytical themes, with descriptive subthemes, were identified that related to issues of importance to stroke survivors: (1) physical activity is valued; (2) bored and alone; (3) patient-centered therapy; (4) recreation is also rehabilitation; (5) dependency and lack of control; (6) fostering autonomy; (7) power of communication and information; (8) motivation needs nurturing; and (9) fatigue can overwhelm. The thematic synthesis provides new insights into stroke survivors' experiences of inpatient rehabilitation. Negative experiences were reported in all studies and include disempowerment, boredom, and frustration. Rehabilitation could be improved by increasing activity within formal therapy and in free time, fostering patients' autonomy through genuinely patient

    Full Text Available Introduction: Stroke is the leading cause of disability in the elderly and significant source of disability. In the stroke patients the occurrence of fall is one of the essential factors hindering the rehabilitation process. Asymmetrical weight bearing is the major cause for frequent falls in stroke patients. Materials & Methods: In this study 15 patients subjected to Symmetrical weight bearing along with conventional stroke training in Experimental group. Other 15 patients subjected to conventional stroke training alone in control group. After 3 months of training period the pre and post test values of frequency of falls were compared. Results: As per the study results the mean difference of reduced number of falls in experimental group was 5.8 and the mean difference of reduced number of falls in control group was 2.86. The calculated value of experimental group was 31.8 whereas in control group 14.3. Discussion: Stroke patients can be trained easily with conventional weight training exercise which is highly beneficial. Further study can be done with huge number of stroke patients. Conclusion: The study concluded that the number of falls in stroke cases were reduced significantly by using symmetrical weight training exercise and conventional stroke training compared to conventional stroke training alone

    Full Text Available Abstract Among patients with ischemic stroke, little attention has been paid to differentiation between stroke progression and recurrence. We assessed the role of MR imaging in predicting stroke progression, recurrent stroke, and death within 2 years of symptom onset. Methods Ischemic stroke or TIA patients were prospectively enrolled. They were examined within 12 hours and had a stroke MR completed within 24 hours of symptom onset. Patients were closely followed neurologically and examined if there was any deterioration in neurological status. Relationships between baseline clinical and imaging factors and outcomes were assessed. We also examined whether baseline stroke/TIA severity (NIHSS 0-5 versus NIHSS > 5 modified these relationships. Results A total of 334 patients were enrolled. The overall rates of progression, 2-year recurrence, and 2-year death were 8.7%, 8.0%, and 6.6%, respectively. Event rates were similar among patients with mild compared to more severe strokes: 8.3% versus 9.5% (p = 0.73 for progression, and 7.3% versus 9.9% (p = 0.59 for recurrence. The effect of baseline glucose > 8 mmol/l was consistent in predicting stroke progression, recurrent stroke and death, regardless of baseline stroke severity. In multivariable analyses, DWI lesion and intracranial occlusion predicted stroke progression only in the minor stroke/TIA group; symptomatic Internal Carotid Artery (ICA stenosis predicted stroke recurrence only in the minor stroke/TIA group. Conclusions In a prospective study with early assessment and imaging we have found that stroke progression is different than stroke recurrence. Different imaging factors predict stroke progression versus stroke recurrence. Baseline hyperglycemia, a potentially modifiable factor, consistently predicted all three outcomes (stroke progression, recurrent stroke or death regardless of baseline stroke severity.

    Telemedicine has potential to increase the use of tissue plasminogen activator (t-PA) for ischemic stroke and is increasingly offered to provide stroke expertise to remote and underserved areas. The accuracy of stroke neurologists' use of telemedicine to read head computed tomography scans (CT) has not been demonstrated. We sought to determine the validity and reliability of neurologists' reading of acute stroke head CTs via teleradiology. The pilot study compared stroke neurologists' reading of CTs via teleradiology to gold standard readings of hard copies on a view box. Head CTs obtained during consecutive acute evaluations for thrombolytic therapy between February and July 2001 were used. For this study, each stroke neurologist was masked to all prior readings, clinical decisions regarding thrombolysis eligibility, and the reading of the other study neurologist. Each neurologist read one-half of the CT scans using teleradiology and the other one-half using a view box. We used the official reading by a neuroradiologist for comparison. The kappa statistic measured reliability. Validity was measured by sensitivity and specificity. Sixty scans were used for the analysis. The neurologists identified the same four hemorrhages using teleradiology that they and the neuroradiologist identified using the light board. Compared to the readings on a view box, the kappa statistic for eligibility for thrombolysis via teleradiology was 1.0. Sensitivity was 100%, 95% CI = (0.93, 1.0); specificity was 100%, 95% CI = (0.40, 0.98) in both comparisons. This pilot study provides encouraging preliminary evidence that neurologists with stroke expertise can determine radiological intravenous t-PA eligibility via teleradiology. Further analysis in a larger sample is necessary to validate these results.

    Full Text Available BACKGROUND: Very little is known about the relationship between non-sickle cell anemia and stroke. The purpose of this study is to evaluate the association of iron-deficiency anemia (IDA with stroke based on a nationwide coverage database in Taiwan. METHODS: The case-control study subjects were obtained from the Taiwanese Longitudinal Health Insurance Database 2000. We included 51,093 subjects with stroke as cases and randomly selected 153,279 controls (3 controls per case in this study.Separate conditional logistic regression analyses were used to calculate the odds ratio (OR for having been previously diagnosed with IDA between cases and controls.We further analyzed the association between stroke and IDA by stroke subtype. RESULTS: Results showed that 3,685 study subjects (1.81% had been diagnosed with IDA prior to the index date; of those subjects, 1,268 (2.48% were cases and 2,417 (1.58% were controls (p<0.001. Conditional logistic regression shows that the OR of having previously received an IDA diagnosis among cases was 1.49 (95% CI: 1.39~1.60; p < 0.01 that of controls after adjusting for monthly income, geographic region, hypertension, diabetes, coronary heart disease, atrial fibrillation, heart failure, hyperlipidemia, tobacco use disorder, and alcohol abuse/alcohol dependency syndrome. Furthermore, the adjusted OR of prior IDA for cases with ischemic stroke was found to be 1.45 (95% CI: 1.34~1.58 compared to controls. However, we did not find any significant relationship between IDA and subarachnoid/intracerebral hemorrhage even adjusting for other confounding factors (OR=1.17, 95% CI=0.97~1.40. CONCLUSION: There is a significant association between prior IDA and ischemic stroke.

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

    Psoriasis is a common, chronic, relapsing, inflammatory skin disorder. Observational studies suggest an association between psoriasis and the incidence of stroke or myocardial infarction (MI). However, whether psoriasis is an independent risk factor for these two vascular events remains controversial. To evaluate the association of psoriasis with stroke and MI by conducting a meta-analysis of cohort studies. Cohort studies were searched in MEDLINE (Pubmed), EMBASE and Cochrane Library from their inception to March 2012. Stroke and MI were considered as a composite endpoint. Two authors independently extracted information on the characteristics of the study participants, follow-up range and control for potential confounding factors. A random-effects model was used to calculate the overall combined risk estimates. Seven cohort studies were included in the meta-analysis. On the basis of cohort characteristics, five of them were considered good quality and two were fair. The overall combined relative risk for psoriasis and composite vascular endpoint was 1·2 (95% confidence interval 1·1-1·31). Subgroup analysis maintained this significance with respect to stroke and MI individually. Sensitivity analysis and 'trim and fill' method yielded similar results. No evidence of publication bias was observed. This meta-analysis of cohort studies suggests that psoriasis significantly increases the risk of stroke and MI. The increase is probably independent of conventional cardiovascular risk factors. © 2012 The Authors. BJD © 2012 British Association of Dermatologists.

    Full Text Available Introduction: Stroke is the leading cause of death and the most common cause of disability. This study determined the effects of Treadmill Aerobic Exercise on spatial and temporal gait parameters among stroke patients. Materials & Methods: In this study, Thirty -nine subjects with hemiparetic stroke underwent Treadmill Aerobic Exercise four times weekly for six months from December 2006 to June 2007. This study has taken place in Department of Physical therapy and Rehabilitation, GSN multi Specialty hospital and research Centre, Hyderabad, India. We measured the spatial and temporal gait parameters of the subjects before and after Treadmill Aerobic Exercise training by the means of 30-foot timed walks, 6 minute distance walks with usual assistive devices and 8metre instrumented walkway without assistive devices. Pre and post training results were compared and contrast. Results: This study results that the Treadmill Aerobic Exercise improved 30-foot walks by 17% and 6 minute walk by 23%. Unassisted walking velocity increased 22%, stride length increased 13% and cadence increased 7%. Paretic and non-paretic step lengths increased significantly, and respective step times increased significantly. Discussion: Large study should be done with treadmill exercise training along with other skills for the better results to improve the gait parameters in chronic stroke cases. Conclusion: This study shows the evidence for positive changes in spatial and temporal gait parameters of subjects with stroke after Treadmill Aerobic Exercise.

    Acute ischemic stroke diagnosis and treatment are among the most challenging in Emergency Medicine. Perfusion computed tomography (CTP) can increase the sensitivity for detecting ischemic stroke and, especially with the addition of CT angiography (CTA), improve decision-making regarding thrombolytic therapy compared to non-contrast computed tomography (NCCT) alone. However, because acute stroke protocols do not generally include procedures for multimodal imaging, they are not commonly performed. In addition, there is concern that additional studies could delay or preclude therapy in patients otherwise eligible for thrombolytic therapy. To demonstrate the feasibility of perfusion CTP and CTA in addition to NCCT of the brain in the emergency assessment of patients with acute ischemic stroke. Starting January 2008, multimodal (CTP and CTA) imaging was added to NCCT in the Emergency Department (ED) initial assessment of patients with stroke of ≤ 5 h duration. Over the subsequent 9 months, we measured the time from ED arrival to imaging and to recombinant tissue plasminogen activator (rt-PA) treatment and compared these times to patients evaluated with CT alone. From January to October 2008, 95 patients had CTP and CTA studies in addition to NCCT for acute ischemic stroke. There were no differences between the average time to CT study or to rt-PA treatment between patients evaluated with multimodal CT imaging and patients assessed with NCCT alone. Combining CTP and CTA with NCCT is feasible and does not adversely increase the time to CT imaging or rt-PA treatment in patients with acute ischemic stroke. Copyright © 2012 Elsevier Inc.

    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.

    Health care improvements have led to increased survival among stroke patients; however, the disability level remains high. These patients require assistance from caregivers, particularly in the first year after stroke. Longitudinal studies of quality of life (QoL) and the factors associated with QoL for both patients and caregivers are limited. To describe the changes in QoL and determine the factors associated with QoL for both stroke patients and their informal caregivers in the first year after stroke. This multicenter prospective study was conducted in public hospitals in Mongolia. In this study, 155 first-time stroke patients and their 88 informal caregivers were followed up for 1 year. The WHOQOL-BREF questionnaire was used to assess QoL. The Barthel Index was administered to the patients at the baseline and after 1 year. A generalized estimating equation analysis was used to determine the factors associated with QoL. The QoL of stroke patients in the domains of physical and environmental aspects improved significantly (p caregivers, psychological health and social relationship domains improved significantly. Factors associated with low QoL among stroke patients were advancing age, male patients, being single and less improvements on BI score, and among caregivers were poor physical health and financial difficulties. Efficient rehabilitation therapy for poststroke patients can improve their QoL. Disability training and financial support for caregivers of poststroke patients might be helpful; however, further research is required. Copyright © 2016 Elsevier Inc. All rights reserved.

    Chronic kidney disease is associated with an increased risk of cardiovascular events. However, the impact of chronic kidney disease on cerebrovascular disease is less well understood. We hypothesized that renal function severity would be predictive of stroke risk, independent of other vascular risk factors. The study population included 3939 subjects enrolled in the Chronic Renal Insufficiency Cohort (CRIC) study, a prospective observational cohort. Stroke events were reported by participants and adjudicated by 2 vascular neurologists. Cox proportional hazard models were used to compare measures of baseline renal function with stroke events. Multivariable analysis was performed to adjust for key covariates. In 3939 subjects, 143 new stroke events (0.62 events per 100 person-years) occurred over a mean follow-up of 6.4 years. Stroke risk was increased in subjects who had worse baseline measurements of renal function (estimated glomerular filtration rate and total proteinuria or albuminuria). When adjusted for variables known to influence stroke risk, total proteinuria or albuminuria, but not estimated glomerular filtration rate, were associated with an increased risk of stroke. Treatment with blockers of the renin-angiotensin system did not decrease stroke risk in individuals with albuminuria. Proteinuria and albuminuria are better predictors of stroke risk in patients with chronic kidney disease than estimated glomerular filtration rate. The impact of therapies targeting proteinuria/albuminuria in individuals with chronic kidney disease on stroke prevention warrants further investigation. © 2015 American Heart Association, Inc.

    This pilot study aimed to evaluate the effectiveness of multiple sessions of transcranial Direct Current Stimulation (tDCS) during 4 weeks on balance and gait parameters after stroke. Thirty-one stroke patients were included in this randomised, double-blind, sham-controlled crossover study. The Tinetti test was used to assess functional balance and gait after stroke. Secondary measures, Rivermead Motor Assessment (RMA) and Trunk Impairment Scale (TIS), were registered to asses both motricity and trunk performance. All tests were administered at baseline, after 4 and 8 weeks. Patients were randomly divided into two groups. Both groups received both sixteen 20-min sessions of tDCS and sixteen 20-min sessions of Sham stimulation. Application method between groups was changed after 4 weeks. A general linear repeated measures model was used to analyse the results of our study. Results revealed an effect on the total score of the Tinetti test (p = 0.049). No significant results were obtained for the RMA (p = 0.166) and the TIS (p = 0.479). This pilot study indicates that 16 tDCS-sessions could have a beneficial effect on balance and gait in stroke patients measured with the Tinetti test. However, further research is needed to elucidate these findings. Implications for Rehabilitation Sixteen sessions of tDCS is beneficial in the recovery of postural control in stroke patients. tDCS has to be applied as soon as possible to enhance beneficial effects.

    Little is known about the impact of premorbid undernutrition on stroke outcome in developing countries. To study the impact of premorbid undernutrition status, measured by the Subjective Global Assessment (SGA) tool, on short term stroke outcome. First ever stroke patients admitted to six major hospitals in North and South India participated in this study from 1 March 2008 to 30 September 2009. The SGA tool was administered within 48 h of stroke onset, and 6 months premorbid nutritional status was rated as well nourished (A rating) and undernourished (B and C ratings) using this tool. Stroke outcome was assessed after 30 days using the modified Rankin scale (mRs), and a mRs score >3 was defined as a poor outcome. Statistical analyses were performed using SPSS Statistics V.17.0. Of 477 patients enrolled, 448 patients were included in the analyses. Mean age was 58.1±13.7 years (range 16-96) and 281 (62.7%) patients were men. At admission, premorbid undernutrition was found in 121 (27.2%) patients. Older age (OR 4.99, CI 1.26 to 19.64, p=0.021), hypertension (OR 1.99, CI 1.04 to 3.79, p=0.037) and patients from Andhra Pradesh State (OR 1.87, CI 1.05 to 3.32, p=0.032) were predictors of undernutrition in multiple logistic regression analysis. Premorbid undernutrition (OR 1.99, CI 1.20 to 3.31, p=0.007) and length of hospital stay (OR 3.41, CI 1.91 to 6.06, pstroke patients were found. Age, hypertension and patients from Andhra Pradesh State were predictors of premorbid undernutrition. Premorbid undernutrition was associated with poor stroke outcome. The results provide opportunities for primary prevention and improving stroke outcome.

    Full Text Available Diet appears to have some role in stroke development. The objective of our study was to describe the dietary habits in patients admitted with acute ischemic stroke and compare selected dietary components with healthy controls. Adherence to healthy diet behaviors was also assessed.A case-control study of consecutive patients with acute ischemic stroke admitted to the Neurology Department of Hospital del Mar from 2007 to 2010. Patients were matched by age and sex with control subjects. A previously validated nutritional survey was administered to patients and controls. Demographic data, vascular risk factors, caloric intake and dietary nutrients were evaluated. Intention to follow a healthy diet was also assessed in both groups.A total of 300 acute ischemic stroke patients and 300 controls with evaluation of dietary habits. No differences were observed in vascular risk factors, except smoking habit, diabetes and ischemic heart disease. Stroke patients reported a higher caloric intake: 2444.8(1736.8-3244.5 vs 2208.7(1753.1-2860.7 Kcal, p = 0.001. After adjusting for energy intake, patients had higher intake of proteins (p<0.001; OR 1.02, total cholesterol (p = 0.001; OR 1.04, and breaded foods (p = 0.001; OR 1.94 and lower consumption of probiotic yogurt (p = 0.002; OR 0.88.

    Objective Previous studies have speculated that the higher stroke incidence rate in blacks compared with whites may be due, in part, to stroke risk factors exerting a more adverse effect among blacks than whites. To determine whether such racial differences exist we compared the prospective associations between novel, traditional and emerging stroke risk factors in blacks and whites. Design Baseline characteristics on risk factor levels were obtained on 15,407 participants from the Atherosclerosis Risk in Communities Study. Stroke incidence was ascertained from 1987–2008. Adjusted Cox proportional hazard models were used to compute hazard ratios (HRs) and their 95% confidence intervals (CIs) for stroke in relation to stroke risk factor levels stratified by race. Results During follow-up 988 stroke events occurred: Blacks had higher stroke incident rates compared with whites with the greatest difference in those aged <60 years: 4.34, 3.24, 1.20 and 0.84 per 1,000 person-years, in black men, black women, white men and white women, respectively. Associations between risk factors with incident stroke were similar in blacks and whites excluding diabetes which was more strongly associated with risk of stroke in blacks than in whites: HR 2.54 (95% CI: 2.03–3.18) vs. 1.74 (1.37–2.21), respectively; p for race interaction=0.02. Conclusions At all ages, blacks are at considerably higher risk of incident stroke compared with whites, although the effect is most marked in younger age groups. This is most likely due to blacks having a greater burden of stroke risk factors rather than there being any substantial race differences in the associations between risk factors and stroke outcomes.

    Background and Purpose Dizziness, vertigo, and imbalance are common presenting symptoms in the emergency department. Stroke is a leading concern even when these symptoms occur in isolation. The objective of the present study was to determine the “real-world” proportion of stroke among patients presenting to the emergency department with these dizziness symptoms (DS). Methods From a population-based study, patients >44 years of age presenting with DS to the emergency department, or directly admitted to the hospital, were identified. Demographics, the frequency of new cerebrovascular events, and the frequency of isolated DS (ie DS with no other stroke screening term or accompanying neurologic signs or symptoms) were assessed. Multivariable logistic regression was used to evaluate the association of age, gender, ethnicity, and isolated DS with stroke/transient ischemic attack (TIA). The association of the presenting symptoms with stroke/TIA was also assessed. Results Stroke/TIA was diagnosed in 3.2% (53 of 1666) of all patients with DS. Only 0.7% (9 of 1297) of those with isolated DS had a stroke/TIA. Patients with stroke/TIA were slightly older than those without stroke/TIA (69.3±11.7 vs 65.3±12.9, P=0.02). Male gender was associated with stroke/TIA, whereas isolated DS was negatively associated with stroke/TIA. Patients with imbalance (dizziness as referent) were more likely to have stroke/TIA. Conclusions The proportion of cerebrovascular events in patients presenting with dizziness, vertigo, or imbalance is very low. Isolated dizziness, vertigo, or imbalance strongly predicts a noncerebrovascular cause. The symptom of imbalance is a predictor of stroke/TIA. PMID:16946161

    A frequently used clinical test to assess mobility after stroke is the Timed Up & Go. Knowledge regarding whether or not the Timed Up & Go is able to detect change over time in patients with stroke, whether improvements in mobility exist after the first three months and whether or not longitudinal change in mobility after stroke depend on the patients' age, is limited or unclear. The objectives were to investigate the distribution-based responsiveness of the Timed Up & Go (TUG) during the first three months after a first event of stroke, to measure the longitudinal change in TUG time during the first year after stroke and to establish whether recovery in TUG time differs between different age groups. Ninety-one patients with first-ever stroke were assessed using the Timed Up & Go at the 1st week and at 3, 6 and 12 months after stroke. The non-parametric sign-test, the parametric t-test and a mixed model approach to linear regression for repeated measurements (Proc mixed) were used for the statistical analyses. The median TUG time was reduced from 17 to 12 seconds (p time between 3 and 12 months after stroke, while patients time). The Timed Up & Go demonstrates ability to detect change in mobility over time in patients with stroke. A significant improvement in TUG time from the 1st week to 3 months after stroke was found, as expected, but thereafter no statistically significant change was detected. After 3 months, patients ≥80 years tended to deteriorate in terms of TUG time, while the younger patients did not.

    Near surface geophysics are gaining widespread use in major infrastructure projects with respect to geotechnical and engineering applications. The development of data acquisition, processing tools and interpretation methods have optimized survey production, reduced logistics costs and increase results reliability of seismic surveys during the last decades. However, the use of geophysical methods under urban environments continues to face challenges due to multiple noise sources and obstacles inherent to cities. A seismic investigation was conducted in Copenhagen aiming to produce information needed for hydrological, geotechnical and groundwater modeling assessments related to the planned Cityringen underground metro project. The particular objectives were a) map variations in subsurface Quaternary and limestone properties b) to map for near surface structural features. The geological setting in the Copenhagen region is characterized by several interlaced layers of glacial till and meltwater sand deposits. These layers, which are found unevenly distributed throughout the city and present in varying thicknesses, overlie limestone of different generations. There are common occurrences of incised valley structures containing localized instances of weathered or fractured limestone. The surveys consisted of combined seismic reflection and refraction profiles accounting for approximately 13 km along sections of the projected metro line. The data acquisition was carried out using standard 192 channels arrays, receiver groups with 5 m spacing and a Vibroseis as a source at 5 m spacing. In order to improve the resolution of the data, 29 Walkaway-Vertical Seismic Profiles were performed at selected wells along the surface seismic lines. The refraction data was processed with travel-time tomography and the reflection data underwent standard interpretation. The refraction data inversion was performed twofold; a surface refraction alone and combined with the VSP data. Three

Together with a variety of biochemical variables, these analyses describe important physiological and pathophysiological relations. There is a need for research databases to explore associations between these parameters, concurrent comorbidities, and future disease outcomes.Methods and results: The Copenhagen General Practitioners’ Laboratory is the only laboratory serving general practitioners in the Copenhagen area, covering approximately 1.2 million inhabitants. The Copenhagen General Practitioners’ Laboratory has registered all analytical results since July 1, 2000. The Copenhagen Primary Care Differential Count database contains all differential blood cell count results (n=1,308,022 from July 1, 2000 to January 25, 2010 requested by general practitioners, along with results from analysis of various other blood components. This data set is merged with detailed data at a person level from The Danish Cancer Registry, The Danish National Patient Register, The Danish Civil Registration System, and The Danish Register of Causes of Death.Conclusion: This paper reviews methodological issues behind the construction of the Copenhagen Primary Care Differential Count database as well as the distribution of characteristics of the population it covers and the variables that are recorded. Finally, it gives examples of its use as an inspiration to peers for collaboration

    Full Text Available Restoring mobility and rehabilitation of gait are high priorities for post-stroke rehabilitation. Cueing using metronomic rhythmic sensory stimulation has been shown to improve gait, but most versions of this approach have used auditory and visual cues. In contrast, we developed a prototype wearable system for rhythmic cueing based on haptics, which was shown to be highly effective in an early pilot study. In this paper we describe a follow-up study with four stroke survivors to inform design, and to identify issues and requirements for such devices to be used in home-based or out-door settings. To this end, we present a blended user-centred design study of a wearable haptic gait rehabilitation system. This study draws on the combined views of physiotherapists, nurses, interaction designers and stroke survivors. Many of the findings were unanticipated, identifying issues outside the scope of initial designs, with important implications for future design and appropriate use.

    Full Text Available BACKGROUND Stroke is usually end result of predisposing conditions that originated years before the ictus. Creating awareness and treatment of its modifiable risk factors will reduce the incidence of stroke. OBJECTIVE To study the risk factors and lipid profile pattern in stroke patients. METHODS Patients with diagnosis of stroke comprising 50 consecutive patients each of ischaemic and haemorrhagic strokes who were admitted in Jorhat Medical College & Hospital, Assam over a period of 1 year (May 2015 - April 2016 included in the study, while patients on lipid lowering therapy were excluded from the study. History of risk factors like hypertension, diabetes mellitus, smoking and alcoholism were taken. To determine the subtype of stroke, clinical examination followed by CT scan/MRI of brain were done. A serum sample after 8 hours of overnight fasting was taken on the next day of admission for both groups of patients. Total serum cholesterol, triglycerides, LDL-cholesterol, VLDL-cholesterol and HDL-cholesterol was determined, using enzymatic colorimetric method. RESULTS A total of 100 patients were studied, of whom 66 were males and 34 were females. The mean age for the ischaemic group was 62±12 years and for the haemorrhagic group were 55±14 years. In this study, dyslipidaemia was present in 58 (58% patients. Patients with high total cholesterol - 33 (18 ischaemic, 15 haemorrhagic, high LDL-cholesterol was found in 38 (22 ischaemic, 16 haemorrhagic, high triglycerides in 31 (14 ischaemic, 17 haemorrhagic and low HDL-cholesterol in 47 (29 ischaemic, 18 haemorrhagic. Among 100 patients, 66 had hypertension, 20 had diabetes mellitus, 18 had both diabetes and hypertension, 43 were smokers, 36 consumed alcohol and >2 risk factor were found in 44. CONCLUSION Dyslipidaemia was found in 58% of patients and most striating features were low HDL-cholesterol and elevated triglycerides level, indicating they are independent risk factors for stroke. No
