  1. Stroke risk perception among participants of a stroke awareness campaign


    Kraywinkel, Klaus; Heidrich, Jan; Heuschmann, Peter U; Wagner, Markus; Berger, Klaus


    Abstract Background Subjective risk factor perception is an important component of the motivation to change unhealthy life styles. While prior studies assessed cardiovascular risk factor knowledge, little is known about determinants of the individual perception of stroke risk. Methods Survey by mailed questionnaire among 1483 participants of a prior public stroke campaign in Germany. Participants had been informed about their individual stroke risk based on the Framingham stroke risk score. S...

    Full Text Available Objective. To compare participation in moderate to high intensity physical activities in persons before and after a mild stroke. Methods. We used data from the Cognitive Rehabilitation and Research Group to examine changes in moderate to high intensity physical activity participation in persons who had a mild stroke as defined by an NIH Stroke Scale score of less than 6 (N=127. Using the Activity Card Sort, we compared the participants' high-demand leisure activity (leisure activities that are moderate to high intensity physical activities participation at 6-months after stroke with their prestroke level. Results. We found a significant decrease in numbers of high-demand leisure activities in all participants and in each demographic group after mild stroke. Conclusion. These results suggest that persons after mild stroke are not retaining the high-demand leisure activities they were doing prior to their stroke. Health professionals must promote participation in high-demand leisure activities in patients with mild stroke as a tool to enhance health and fitness.

  3. Links between emotion perception and social participation restriction following stroke. (United States)

    Cooper, Clare L; Phillips, Louise H; Johnston, Marie; Radlak, Bogumila; Hamilton, Steven; McLeod, Mary Joan


    Stroke can cause impairment in emotion perception, but the social consequences of these problems have not been explored to date. In a group of patients with stroke, this study investigated whether difficulties in emotion perception related to social participation and quality-of-life. It also assessed whether these relationships remained significant when controlling for activity limitations. Individuals 1 year post-stroke (n = 28) and control participants (n = 40) were assessed on emotion perception across different modalities. Activity limitations, social participation, and multiple domains of quality-of-life were assessed in patients. Participants with stroke were impaired on emotion perception compared to controls. Emotion perception problems in stroke were significantly correlated with social participation and psychological aspects of QoL, but not with activity limitations. The strong relationships of emotion perception with social participation and psychological aspects of QoL following stroke may have implications for post-stroke outcomes.

    Full Text Available Loss to follow-up can introduce bias into research, making it difficult to develop inclusive evidence-based health policies and practice guidelines. We aimed to deepen understanding of reasons why participants leave or remain in longitudinal health studies. We interviewed 59 researchers and current and former research participants in six focus groups (n = 55 or interviews (n = 4 at three study centers in a large academic research institution. We used minimally structured interview guides and inductive thematic analysis to explore participant-level, study-level, and contextual participation barriers and facilitators. Four main themes emerged: transportation, incentives and motivation, caregiver concerns, and the social and physical environment. Themes shared crosscutting issues involving funding, flexibility, and relationships between researchers and research participants. Study-level and contextual factors appear to interact with participant characteristics, particularly socioeconomic status and disease severity to affect participant retention. Participants’ characteristics do not seem to be the main cause of study dropout. Researchers and funders might be able to address contextual and study factors in ways that reduce barriers to participation.

  5. The role of emotion regulation on social participation following stroke. (United States)

    Cooper, Clare L; Phillips, Louise H; Johnston, Marie; Whyte, Maggie; MacLeod, Mary J


    Following stroke, individuals often experience reduced social participation, regardless of physical limitations. Impairments may also occur in a range of cognitive and emotional functions. Successful emotion regulation, which has been identified as important in psychological adaptation to chronic illness, is associated with better perceived psychological well-being and social functioning. However, there is little evidence about the effect of stroke on emotion regulation difficulties, and associated impact on important outcomes in recovery from stroke. The objectives were (1) to determine whether people who have had a stroke reported greater difficulties in emotion regulation than controls and (2) to establish whether emotion regulation difficulties relate to social participation. 75 stroke and 40 healthy participants completed measures of emotion regulation (DERS), social participation (Modified Functional Limitation Profile [mFLP], WHOQoL-Bref) and activity limitations (mFLP). Stroke participants were seen at the acute stage (63 days post-stroke) for Study 1 and 18 months post-stroke for Study 2. In Study 1, acute-stage stroke patients had significant impairments on impulse control, awareness of emotions, and strategies for emotion regulation. There was also evidence that emotion regulation difficulties (impulse control, awareness and clarity about emotions) were associated with social participation in the stroke sample, even after controlling for potential confounders. In Study 2, there was evidence that, in the chronic-stage post-stroke, difficulties with strategy and acceptance of emotions were associated with social participation restrictions. Whilst emotion regulation as a whole in the acute phase predicted social participation in the chronic phase of stroke, no one domain of emotion regulation was a significant predictor of social participation >1 year later. These results indicate that multiple aspects of emotion regulation are impaired following stroke

  6. Participation in leisure activities after stroke: A survey of community-residing stroke survivors in Nigeria. (United States)

    Vincent-Onabajo, Grace; Blasu, Cephas


    Leisure provides pleasure and relaxation, and has health benefits even after a stressful and life-changing event such as a stroke. This study examined leisure participation among a sample of community-residing stroke survivors in Nigeria. Fifty-five stroke survivors undergoing rehabilitation were consecutively recruited from two government hospitals in Northern Nigeria. Data on pre- and post-stroke participation, and socio-demographic (age, sex, marital, employment, and educational status) and clinical (level of disability, post-stroke duration, stroke type and side of hemiplegia/hemiparesis) attributes of the stroke survivors were obtained. Leisure participation was assessed in four domains of recreational, social, cognitive, and productive/creative activities. Associations between leisure participation and the socio-demographic and clinical variables were examined using bivariate analysis. Mean (SD) age of the stroke survivors was 53.55 (14.39) years. Prevalence of leisure participation was 89.1%. Participation in specific leisure domains however varied thus: social (83.6%), cognitive (60%), recreational (41.8%), productive/creative activities (30.9%). Significant associations were observed between participation in cognitive, productive/creative, and recreational leisure activities, and specific socio-demographic and clinical attributes. Leisure participation was high in a general sense but marginal in recreational and productive/creative activities. The observed socio-demographic and clinical associations with post-stroke leisure participation may assist in providing effective leisure rehabilitation strategies.

The sample was obtained by convenience sampling and is obviously small because recruitment was done only once on the particular occasion of a stroke awareness event. All test measurements were carried out by a team of six doctors, two physiotherapists, four nurses.

  9. Participation Changes in Sexual Functioning after Mild Stroke (United States)

    Seymour, Lisa M.; Wolf, Timothy J.


    The purpose of this study was to explore the extent to which persons with mild stroke experience changes in participation in sexual activity post-stroke. A cross-sectional study was completed with adults 6-18 months post-mild stroke (n = 13); a brief case study was also completed with one of the participants. Participants completed an assessment battery over the phone that included the modified Quality of Sexual Function Scale (QSF), the Stroke Impact Scale (SIS), and the Patient Health Questionnaire-9 (PHQ-9). The sample reported mild problems with sexual dysfunction (M = 10.77, SD = 4.09). Sexual dysfunction post-stroke was highly correlated (r2 = −.372 to −.875) with all the domains on the SIS. Several of the participants in this study reported that they would have liked more information about sexual functioning following stroke. These findings suggest that individuals with mild stroke are experiencing decreased participation in sexual activities post-stroke and that they would like more information from the health care community on the potential sexual changes.

  10. Art participation for psychosocial wellbeing during stroke rehabilitation: a feasibility randomised controlled trial. (United States)

    Morris, Jacqui H; Kelly, Chris; Joice, Sara; Kroll, Thilo; Mead, Gillian; Donnan, Peter; Toma, Madalina; Williams, Brian


    To examine the feasibility of undertaking a pragmatic single-blind randomised controlled trial (RCT) of a visual arts participation programme to evaluate effects on survivor wellbeing within stroke rehabilitation. Stroke survivors receiving in-patient rehabilitation were randomised to receive eight art participation sessions (n = 41) or usual care (n = 40). Recruitment, retention, preference for art participation and change in selected outcomes were evaluated at end of intervention outcome assessment and three-month follow-up. Of 315 potentially eligible participants 81 (29%) were recruited. 88% (n = 71) completed outcome and 77% (n = 62) follow-up assessments. Of eight intervention group non-completers, six had no preference for art participation. Outcome completion varied between 97% and 77%. Running groups was difficult because of randomisation timing. Effectiveness cannot be determined from this feasibility study but effects sizes suggested art participation may benefit emotional wellbeing, measured on the positive and negative affect schedule, and self-efficacy for Art (d = 0.24-0.42). Undertaking a RCT of art participation within stroke rehabilitation was feasible. Art participation may enhance self-efficacy and positively influence emotional wellbeing. These should be outcomes in a future definitive trial. A cluster RCT would ensure art groups could be reliably convened. Fewer measures, and better retention strategies are required. Implications for Rehabilitation This feasibility randomised controlled trial (RCT) showed that recruiting and retaining stroke survivors in an RCT of a visual arts participation intervention within stroke rehabilitation was feasible. Preference to participate in art activities may influence recruitment and drop-out rates, and should be addressed and evaluated fully. Art participation as part of rehabilitation may improve some aspects of post-stroke wellbeing, including positive affect and self-efficacy for art

  11. Impact of social support on participation after stroke in Nigeria. (United States)

    Vincent-Onabajo, Grace Oluwatitofunmi; Ihaza, Louis Oselene; Usman Ali, Muhammad; Ali Masta, Mamman; Majidadi, Rebecca; Modu, Ali; Umeonwuka, Chuka


    Participation which entails involvement in life situations and represents a higher level of functioning can be severely restricted after a stroke. This study investigated the impact of social support on participation of stroke survivors in Nigeria. Ninety-six community-residing stroke survivors were recruited from physiotherapy outpatient departments of two tertiary care hospitals in Northern Nigeria. Socio-demographic, clinical, participation (London Handicap Scale), and social support (Multidimensional Scale of Perceived Social Support) data were obtained. The impact of social support on global and domain-specific participation was examined using bivariate analyses and multiple regression analyses. Mean (SD) age of the stroke survivors was 56.6 (12.0) years. Social support was a significant (β = 0.41, p participation (p Social support, however, had no independent effect on overall participation and the other participation domains namely mobility, physical independence, occupation, social integration, and orientation. The impact of social support was significant only in the economic self-sufficiency domain of participation with higher availability of social support related to better economic self-sufficiency. This finding provides additional information on the importance of social support post-stroke.

  12. Participants with schizophrenia retain the information necessary for informed consent during clinical trials (United States)

    Fischer, Bernard A.; McMahon, Robert P.; Meyer, Walter A.; Slack, Daniel J.; Appelbaum, Paul S.; Carpenter, William T.


    Objective Cognitive impairment is a characteristic of schizophrenia. This impairment may affect the retention of information required for ongoing knowledgeable participation in clinical trials. This study monitored retention of study-related knowledge--including assessment of therapeutic misconception--in people with stable, DSM-IV schizophrenia during participation in placebo-controlled clinical trials of adjunctive agents. Stability was defined as being on an antipsychotic with no change in medication or dose over the previous 4 weeks. Method Individuals enrolling in one of seven clinical trials were approached for participation. Participants came from research clinics and community mental health centers. At baseline, clinical trial consent forms were reviewed and study knowledge assessed. Participants were randomized to follow-up assessments at weeks 1, 4, and 8; weeks 4 and 8; or at week 8 only. Clinical trial consent forms were not re-reviewed at any follow-up visit. Results Fifty-nine participants were enrolled; analysis included 52 participants with at least one follow-up visit. Study knowledge did not decrease meaningfully in any group. Therapeutic misconception was not observed in participants during the study. The group assessed most frequently demonstrated significant improvement over baseline (t44= 3.43, p= 0.001). Retention of study knowledge was not related to symptoms, but had a weak correlation with cognitive capacity (R= 0.28, p= 0.07). Performance did not differ between participants from research clinics and those from community mental health centers. Conclusions Clinically-stable people with schizophrenia enrolling in a placebo-controlled adjunctive medication study, once determined to have capacity to consent to a clinical trial, retained appropriate study knowledge for at least 8 weeks. In the absence of a specific reason to suspect a loss of decisional capacity, there appears to be no need to routinely re-evaluate participants during this type

  13. Review Strategies to Recruit and Retain Rural Patient Participating Self-management Behavioral Trials. (United States)

    Young, Lufei; Barnason, Susan; DO, VAN


    Self-management plays a vital role in improving health outcomes and reducing costs in patients with cardiovascular disease (CVD) and associated risk factors. Based on existing studies, rural residents with CVD and/or risk factors show low engagement in self-management behaviors. Due to low participation in behavioral intervention trials, the most promising mechanism to promote self-management among rural populations is unknown. In turn, the purpose of this article is to review the evidence that supports strategies to recruit and retain rural patients to participate in behavioral intervention trials aimed to promote self-management of CVD and its risk factors. This review is expected to assist researchers in identifying effective solutions to overcome barriers in the recruitment and retention processes when conducting intervention research studies on the self-management of CVD in rural communities.

  14. Association between satisfaction and participation in everyday occupations after stroke. (United States)

    Bergström, Aileen; Guidetti, Susanne; Tham, Kerstin; Eriksson, Gunilla


    Within occupational therapy, it is assumed that individuals are satisfied when participating in everyday occupations that they want to do. However, there is little empirical evidence to show this. The aim of this study is to explore and describe the relation between satisfaction and participation in everyday occupations in a Swedish cohort, 5 years post stroke. Sixty-nine persons responded to the Occupational Gaps Questionnaire (OGQ). The questionnaire measures subjective restrictions in participation, i.e. the discrepancy between doing and wanting to do 30 different occupations in everyday life, and satisfaction per activity. Results were analysed with McNemar/chi-square. Seventy percent of the persons perceived participation restrictions. Individuals that did not perceive restrictions in their participation had a significantly higher level of satisfaction (p = .002) compared to those that had restrictions. Participants that performed activities that they wanted to do report between 79 and 100% satisfaction per activity. In this cohort, there was a significant association between satisfaction and participating in everyday occupations one wants to do, showing that satisfaction is an important aspect of participation and substantiates a basic assumption within occupational therapy. The complexity of measuring satisfaction and participation in everyday occupations is discussed.

  16. Choral singing therapy following stroke or Parkinson's disease: an exploration of participants' experiences. (United States)

    Fogg-Rogers, Laura; Buetow, Stephen; Talmage, Alison; McCann, Clare M; Leão, Sylvia H S; Tippett, Lynette; Leung, Joan; McPherson, Kathryn M; Purdy, Suzanne C


    People with stroke or Parkinson's disease (PD) live with reduced mood, social participation and quality of life (QOL). Communication difficulties affect 90% of people with PD (dysarthria) and over 33% of people with stroke (aphasia). These consequences are disabling in many ways. However, as singing is typically still possible, its therapeutic use is of increasing interest. This article explores the experiences of and factors influencing participation in choral singing therapy (CST) by people with stroke or PD and their significant others. Participants (eight people with stroke, six with PD) were recruited from a community music therapy choir running CST. Significant others (seven for stroke, two for PD) were also recruited. Supported communication methods were used as needed to undertake semi-structured interviews (total N = 23). Thematic analysis indicated participants had many unmet needs associated with their condition, which motivated them to explore self-management options. CST participation was described as an enjoyable social activity, and participation was perceived as improving mood, language, breathing and voice. Choral singing was perceived by people with stroke and PD to help them self-manage some of the consequences of their condition, including social isolation, low mood and communication difficulties. Choral singing therapy (CST) is sought out by people with stroke and PD to help self-manage symptoms of their condition. Participation is perceived as an enjoyable activity which improves mood, voice and language symptoms. CST may enable access to specialist music therapy and speech language therapy protocols within community frameworks.

  17. Characterizing Researchers by Strategies Used for Retaining Minority Participants: Results of a National Survey (United States)

    Butler, James; Quinn, Sandra C.; Fryer, Craig S.; Garza, Mary A.; Kim, Kevin H.; Thomas, Stephen B.


    Limited attention has been given to the optimal strategies for retaining racial and ethnic minorities within studies and during the follow-up period. High attrition limits the interpretation of results and reduces the ability to translate findings into successful interventions. This study examined the retention strategies used by researchers when retaining minorities in research studies. From May to August 2010, we conducted an online survey with researchers (principal investigators, research staff, and IRB members) and examined their use of seven commonly used retention strategies. The number and type of retention strategies used, how these strategies differ by researcher type, and other characteristics (e.g., funding) were explored. We identified three clusters of researchers: comprehensive retention strategy researchers - utilized the greatest number of retention strategies; moderate retention strategy researchers - utilized an average number of retention strategies; and limited retention strategy researchers - utilized the least number of retention strategies. The comprehensive and moderate retention strategy researchers were more likely than the limited retention strategy researchers to conduct health outcomes research, work with a community advisory board, hire minority staff, use steps at a higher rate to overcome retention barriers, develop new partnerships with the minority community, modify study materials for the minority population, and allow staff to work flexible schedules. This study is a novel effort to characterize researchers, without implying a value judgment, according to their use of specific retention strategies. It provides critical information for conducting future research to determine the effectiveness of using a combination of retention strategies. PMID:23764697

  18. Strategies for retaining study participants in behavioral intervention trials: retention experiences of the NIH Behavior Change Consortium. (United States)

    Coday, Mace; Boutin-Foster, Carla; Goldman Sher, Tamara; Tennant, Jennifer; Greaney, Mary L; Saunders, Sandra D; Somes, Grant W


    Failing to retain an adequate number of study participants in behavioral intervention trials poses a threat to interpretation of study results and its external validity. This qualitative investigation describes the retention strategies promoted by the recruitment and retention committee of the Behavior Change Consortium, a group of 15 university-based sites funded by the National Institutes of Health to implement studies targeted toward disease prevention through behavior change. During biannual meetings, focus groups were conducted with all sites to determine barriers encountered in retaining study participants and strategies employed to address these barriers. All of the retention strategies reported were combined into 8 thematic retention categories. Those categories perceived to be most effective for retaining study participants were summarized and consistencies noted among site populations across the life course (e.g., older adults, adults, children, and adolescents). Further, possible discrepancies between site populations of varying health statuses are discussed, and an ecological framework is proposed for use in future investigations on retention.

  19. Survivors of chronic stroke - participant evaluations of commercial gaming for rehabilitation. (United States)

    Paquin, Kate; Crawley, Jamie; Harris, Jocelyn E; Horton, Sean


    There has been an increase in research on the effect that virtual reality (VR) can have on physical rehabilitation following stroke. However, research exploring participant perceptions of VR for post-stroke rehabilitation has been limited. Semi-structured interviews were conducted with 10 chronic stroke participants (10 males, mean age = 72.1, mean time since injury = 38.6 mos.) who had recently completed an upper extremity VR stroke rehabilitation programme. Four main themes emerged: 'the VR experience,' 'functional outcomes,' 'instruction,' and the 'future of VR in stroke rehabilitation,' along with nine sub-themes. Participants illustrated the positive impact that VR training had on their functional abilities as well as their confidence towards completing activities of daily living (ADL). Participants also expressed the need for increased rehabilitation opportunities within the community. Overall, participants were optimistic about their experience with VR training and all reported that they had perceived functional gain. VR is an enjoyable rehabilitation tool that can increase a stroke survivor's confidence towards completing ADL. Implications for Rehabilitation Although there is an increase in rehabilitation programmes geared towards those with chronic stroke, we must also consider the participants' perception of those programmes. Incorporating participant feedback may increase enjoyment and adherence to the rehabilitation programmes. The VR experience, as well as provision of feedback and instruction, are important aspects to consider when developing a VR programme for stroke survivors. VR for rehabilitation may be a feasible tool for increasing the survivors' confidence in completing ADL post-stroke.

  20. Exploring stroke survivor experience of participation in an enriched environment: a qualitative study. (United States)

    White, Jennifer H; Bartley, Emma; Janssen, Heidi; Jordan, Louise-Anne; Spratt, Neil


    Data highlight the importance of undertaking intense and frequent repetition of activities within stroke rehabilitation to maximise recovery. An enriched environment (EE) provides a medium in which these activities can be performed and enhanced recovery achieved. An EE has been shown to promote neuroplasticity in animal models of stroke, facilitating enhanced recovery of motor and cognitive function. However, the benefit of enriching the environment of stroke survivors remains unknown. To qualitatively explore stroke survivors' experience of implementation of exposure to an EE within a typical stroke rehabilitation setting, in order to identify facilitators and barriers to participation. Semi-structured interviews with 10 stroke survivors (7 females and 3 males, mean age of 70.5 years) exposed to an EE for a 2-week period following exposure to routine rehabilitation within a stroke rehabilitation ward. An inductive thematic approach was utilised to collect and analyse data. Qualitative themes emerged concerning the environmental enrichment paradigm including: (1) "It got me moving" - perceived benefits of participation in an EE; (2) "You can be bored or you can be busy." - Attenuating factors influencing participation in an EE; (3) "I don't like to make the staff busier" - limitations to use of the EE. This study provides preliminary support for the implementation of an EE within a typical stroke rehabilitation setting from a patient perspective. Reported benefits included (1) increased motor, cognitive and sensory stimulation, (2) increased social interaction, (3) alleviation of degree of boredom and (4) increased feelings of personal control. However, participants also identified a number of barriers affecting implementation of the EE. We have previously published findings on perceptions of nursing staff working with stroke survivors in this enriched rehabilitation environment who identified that patients benefited from having better access to physical, cognitive

  1. The impact of stroke-related dysarthria on social participation and implications for rehabilitation. (United States)

    Brady, Marian C; Clark, Alexander M; Dickson, Sylvia; Paton, Gillian; Barbour, Rosaline S


    Each year an estimated 30,000-45,000 UK individuals experience stroke-related dysarthria (impairment of movements required to produce speech). Many will experience persistent dysarthria long after discharge from stroke services. Although we have some insight into the impact of other communication impairments, we have very limited information on the impact of dysarthria on social participation. To explore the impact of dysarthria on social participation following stroke. We report data from in-depth semi-structured interviews with 24 individuals with stroke-related dysarthria. Our findings suggest a complex association between the severity of an individual's dysarthria and the impact on their social participation. Participants' descriptions highlighted their experiences of social participation and isolation. We further suggest that, in some cases, the coping strategies adopted by the participants could be seen to further exacerbate this isolation. These results have important implications for the prioritisation, planning and delivery of therapeutic interventions for people with dysarthria. The impact of stroke-related dysarthria transcends the physiological impairment to impact upon individuals' social participation, which is key to the process of rehabilitation. The development and evaluation of the effectiveness of an intervention that addresses these impacts is the next challenge for therapists and researchers working in this area.

    Youth stroke education is promising for the spread of stroke awareness. The aim of this study was to examine whether our stroke awareness teaching materials without teacher's participation can increase student awareness to act fast on suspected stroke signs. We used the face, arm, speech, and time (FAST) mnemonic derived from the Cincinnati Prehospital Stroke Scale. Seventy-three students of the second grade and 72 students of the third grade (age range, 13-15 years) in a junior high school were enrolled in the study. The students were divided into 2 groups: students who received a teacher's lesson (group I) and those who did not receive a teacher's lesson (group II). Students in group II watched an animated cartoon and read a Manga comic in class. All students took the educational aids home, including the Manga comic and magnetic posters printed with the FAST message. Questionnaires on stroke knowledge were examined at baseline and immediately and 3 months after receiving the intervention. At 3 months after the intervention, a significant improvement in understanding the FAST message was confirmed in both the groups (group I, 85%; group II, 94%). Significant increases in the knowledge of risk factors were not observed in each group. Our education materials include a Manga comic, an animated cartoon, and a magnetic poster, without an accompanying teacher's lesson can increase stroke awareness, including the FAST message, in junior high school students.

  3. A robotic object hitting task to quantify sensorimotor impairments in participants with stroke. (United States)

    Tyryshkin, Kathrin; Coderre, Angela M; Glasgow, Janice I; Herter, Troy M; Bagg, Stephen D; Dukelow, Sean P; Scott, Stephen H


    Existing clinical scores of upper limb function often use observer-based ordinal scales that are subjective and commonly have floor and ceiling effects. The purpose of the present study was to develop an upper limb motor task to assess objectively the ability of participants to select and engage motor actions with both hands. A bilateral robotic system was used to quantify upper limb sensorimotor function of participants with stroke. Participants performed an object hit task that required them to hit virtual balls moving towards them in the workspace with virtual paddles attached to each hand. Task difficulty was initially low, but increased with time by increasing the speed and number of balls in the workspace. Data were collected from 262 control participants and 154 participants with recent stroke. Control participants hit ~60 to 90% of the 300 balls with relatively symmetric performance for the two arms. Participants with recent stroke performed the task with most participants hitting fewer balls than 95% of healthy controls (67% of right-affected and 87% of left-affected strokes). Additionally, nearly all participants (97%) identified with visuospatial neglect hit fewer balls than healthy controls. More detailed analyses demonstrated that most participants with stroke displayed asymmetric performance between their affected and non-affected limbs with regards to number of balls hit, workspace area covered by the limb and hand speed. Inter-rater reliability of task parameters was high with half of the correlations above 0.90. Significant correlations were observed between many of the task parameters and the Functional Independence Measure and/or the Behavioural Inattention Test. As this object hit task requires just over two minutes to complete, it provides an objective and easy approach to quantify upper limb motor function and visuospatial skills following stroke.

  4. Self-Perceived Participation and Autonomy at 1-Year Post Stroke: A Part of the Stroke Arm Longitudinal Study at the University of Gothenburg (SALGOT Study). (United States)

    Törnbom, Karin; Hadartz, Kristin; Sunnerhagen, Katharina S


    Identifying factors predicting the long-term outcome of participation and autonomy after stroke is essential for developing individualized rehabilitation interventions. The aim was to describe self-assessed participation and autonomy and to explore factors associated with the same at 1 year post stroke. Participants consisted of 79 persons (mean age = 67) with a first-time stroke at the 1-year follow-up. To investigate perceived participation and autonomy at 1 year, a self-assessment questionnaire, the Impact on Participation and Autonomy-English version (IPA-E) was used. Multivariate logistic regression models were performed using age, gender, stroke severity, and functional dependency at discharge as potential contributors to the perceived level of participation and autonomy. A high percentage (70%-88%) evaluated their functions as fair to very good within all domains of the IPA-E at 1 year post stroke. However, around a fifth experienced their Family role as poor to very poor. Participants' functional dependency at discharge significantly influenced the outcome for the domains of Family role (odds ratio [OR] = 5.66, P Autonomy indoors (OR = 3.44, P autonomy at 1 year post stroke. The results also indicate that supporting indoor autonomy and social relations of persons with stroke during the acute rehabilitation is important to enhance participation and autonomy at 1 year post stroke.

  5. Long-term recovery trajectory after stroke: an ongoing negotiation between body, participation and self. (United States)

    Arntzen, Cathrine; Borg, Tove; Hamran, Torunn


    Research has mainly focused on the first year of recovery trajectory after stroke, but there is limited knowledge about how stroke survivors manage their long-term everyday lives. This study seeks to fill this gap by exploring the long-term (1-13 years) negotiations of stroke survivors when they experience progress, wellbeing and faith in the future. Repeated in-depth interviews were conducted with nine people living with moderate impairment after stroke and their closest relatives. Concepts from phenomenology and critical psychology constituted the frame of reference of the study. The long-term stroke recovery trajectory can be understood as a process of struggling to overcome tensions between three phenomena under ongoing change: the lived body, participation in everyday life and sense of self. During the recovery process, stroke survivors experience progress, well-being and faith in the future when moving towards renewed relationships, characterised by (1) a modified habitual body, (2) repositioned participation in specific everyday life contexts and (3) a transformed sense of self. This study stresses the importance of developing new forms of professional support during the long-term recovery trajectory, to stimulate and increase interaction and coherence in the relationship between the stroke survivor's bodily perception, participation in everyday life and sense of self. The study deepening how the long-term recovery trajectory after stroke is about ongoing embodied, practical and socially situated negotiations. The study demonstrates that the recovery trajectory is a long term process of learning where the stroke survivor, as an embodied agent, gradually modifies new bodily habits, re-position participation and transforming of the self. Health personnel are usually available in the acute and early rehabilitation period. The three phenomenons under ongoing change; "body", "participation" and "self" are at this point just about being moved toward a renewed and

    Context: The currently applied reference ranges for thyroid function are under debate. Despite evidence that thyroid function within the reference range is related with several cardiovascular disorders, its association with the risk of stroke has not been evaluated previously. Design and Setting: We identified studies through a systematic literature search and the Thyroid Studies Collaboration, a collaboration of prospective cohort studies. Studies measuring baseline TSH, free T4, and stroke outcomes were included, and we collected individual participant data from each study, including thyroid function measurements and incident all stroke (combined fatal and nonfatal) and fatal stroke. The applied reference range for TSH levels was between 0.45 and 4.49 mIU/L. Results: We collected individual participant data on 43 598 adults with TSH within the reference range from 17 cohorts, with a median follow-up of 11.6 years (interquartile range 5.1–13.9), including 449 908 person-years. Age- and sex-adjusted pooled hazard ratio for TSH was 0.78 (95% confidence interval [CI] 0.65–0.95 across the reference range of TSH) for all stroke and 0.83 (95% CI 0.62–1.09) for fatal stroke. For the free T4 analyses, the hazard ratio was 1.08 (95% CI 0.99–1.15 per SD increase) for all stroke and 1.10 (95% CI 1.04–1.19) for fatal stroke. This was independent of cardiovascular risk factors including systolic blood pressure, total cholesterol, smoking, and prevalent diabetes. Conclusion: Higher levels of TSH within the reference range may decrease the risk of stroke, highlighting the need for further research focusing on the clinical consequences associated with differences within the reference range of thyroid function.

    Directory of Open Access Journals (Sweden)

    Chang Anne M


    Full Text Available Abstract Background Apart from promoting physical recovery and assisting in activities of daily living, a major challenge in stroke rehabilitation is to minimize psychosocial morbidity and to promote the reintegration of stroke survivors into their family and community. The identification of key factors influencing long-term outcome are essential in developing more effective rehabilitation measures for reducing stroke-related morbidity. The aim of this study was to test a theoretical model of predictors of participation restriction which included the direct and indirect effects between psychosocial outcomes, physical outcome, and socio-demographic variables at 12 months after stroke. Methods Data were collected from 188 stroke survivors at 12 months following their discharge from one of the two rehabilitation hospitals in Hong Kong. The settings included patients' homes and residential care facilities. Path analysis was used to test a hypothesized model of participation restriction at 12 months. Results The path coefficients show functional ability having the largest direct effect on participation restriction (β = 0.51. The results also show that more depressive symptoms (β = -0.27, low state self-esteem (β = 0.20, female gender (β = 0.13, older age (β = -0.11 and living in a residential care facility (β = -0.12 have a direct effect on participation restriction. The explanatory variables accounted for 71% of the variance in explaining participation restriction at 12 months. Conclusion Identification of stroke survivors at risk of high levels of participation restriction, depressive symptoms and low self-esteem will assist health professionals to devise appropriate rehabilitation interventions that target improving both physical and psychosocial functioning.

  9. Individuals' perception about upper limb influence on participation after stroke: an observational study. (United States)

    Banjai, Renata Morales; Freitas, Sandra Maria Sbeghen Ferreira de; Silva, Flavia Paiva da; Alouche, Sandra Regina


    Background Stroke can compromise upper limb performance and influence the individual's participation in real life situations. Objective To investigate how components of body function and activity affect the individuals' self-perception of their participation after stroke. Methods In this observational study, the International Classification of Functioning, Disability and Health was used as model. Body function was assessed by palmar grip and pinch strength; Ashworth modified scale; Fugl-Meyer scale; and Motor-Free Visual Perception Test. The Purdue Pegboard Test and the aiming movement performance measured the activity. Upper limb participation was analyzed by the Hand Function domain of the Stroke Impact Scale (SIS). Thirty-four individuals after chronic stroke were divided into two groups, according to their Hand function SIS scores (severe and non-severe). Differences between groups were analyzed. Relationships between individual variables and the SIS score were verified. A regression model was proposed. Results Strength and the Fugl-Meyer scale score were greater for the non-severe group. Muscle tone was greater for the severe group only in the wrist flexors. None of the activity variables differed between groups. The upper limb Fugl-Meyer score was able to predict 79% of the individuals in SIS Hand Function groups. Conclusion Sensory-motor impairment, as measured by the upper limb Fugl-Meyer scale, can explain the influence of the upper limbs on participation in the individuals' perception.

  10. Rehabilitation Interventions for Improving Social Participation After Stroke: A Systematic Review and Meta-analysis. (United States)

    Obembe, Adebimpe O; Eng, Janice J


    Despite the fact that social participation is considered a pivotal outcome of a successful recovery after stroke, there has been little attention on the impact of activities and services on this important domain. To present a systematic review and meta-analysis from randomized controlled trials (RCTs) on the effects of rehabilitation interventions on social participation after stroke. A total of 8 electronic databases were searched for relevant RCTs that evaluated the effects of an intervention on the outcome of social participation after stroke. Reference lists of selected articles were hand searched to identify further relevant studies. The methodological quality of the studies was assessed using the Physiotherapy Evidence Database Scale. Standardized mean differences (SMDs) and confidence intervals (CIs) were estimated using fixed- and random-effect models. In all, 24 RCTs involving 2042 stroke survivors were identified and reviewed, and 21 were included in the meta-analysis. There was a small beneficial effect of interventions that utilized exercise on social participation (10 studies; SMD = 0.43; 95% CI = 0.09, 0.78;P= .01) immediately after the program ended. Exercise in combination with other interventions (13 studies; SMD = 0.34; 95% CI = 0.10, 0.58;P= .006) also resulted in beneficial effects. No significant effect was observed for interventions that involved support services over 9 studies (SMD = 0.09 [95% CI = -0.04, 0.21];I(2)= 0%;P= .16). The included studies provide evidence that rehabilitation interventions may be effective in improving social participation after stroke, especially if exercise is one of the components. © The Author(s) 2015.

  11. Participation in Leisure Activity and Exercise of Chronic Stroke Survivors Using Community-Based Rehabilitation Services in Seongnam City (United States)

    Yi, Tae Im; Lee, Ko Eun; Ha, Seung A


    Objective To clarify how participation in leisure activities and exercise by chronic stroke survivors differs before and after a stroke. Methods Sixty chronic stroke survivors receiving community-based rehabilitation services from a health center in Seongnam City were recruited. They completed a questionnaire survey regarding their demographic characteristics and accompanying diseases, and on the status of their leisure activities and exercise. In addition, their level of function (Korean version of Modified Barthel Index score), risk of depression (Beck Depression Inventory), and quality of life (SF-8) were measured. Results After their stroke, most of the respondents had not returned to their pre-stroke levels of leisure activity participation. The reported number of leisure activities declined from a mean of 3.9 activities before stroke to 1.9 activities post-stroke. In addition, many participants became home-bound, sedentary, and non-social after their stroke. The most common barriers to participation in leisure activities were weakness and poor balance, lack of transportation, and cost. The respondents reported a mean daily time spent on exercise of 2.6±1.3 hours. Pain was the most common barrier to exercise participation. Conclusion Chronic stroke survivors need information on leisure activities and appropriate pain management. PMID:25932420

  12. Participation in everyday life and life satisfaction in persons with stroke and their caregivers 3-6 months after onset. (United States)

    Bergström, Aileen L; von Koch, Lena; Andersson, Magnus; Tham, Kerstin; Eriksson, Gunilla


    To explore and describe persons with stroke and their caregivers' restrictions in participation in everyday occupations, i.e. occupational gaps, 3-6 months post-stroke, in relation to life satisfaction, combined life satisfaction, care-giver burden, perceived impact of stroke, and activities of daily living. Cross-sectional study. Persons with stroke and their caregivers (105 dyads). The Occupational Gaps Questionnaire, Life Satisfaction Checklist, Caregiver Burden Scale, Stroke Impact Scale and Barthel Index were used. Correlations were analysed with Spearman's rank, and regression analyses used life satisfaction as the dependent variable. At least one person in 86% of the dyads perceived restrictions in participation, with the most common gap in travelling for pleasure. Correlations were low between the numbers of occupational gaps and life satisfaction (R = -0.33, R = -0.31); however, life satisfaction accounted for occupational gaps both for persons with stroke and for caregivers. A greater number of occupational gaps were perceived in the dyads with combined low levels of life satisfaction compared with those with combined high levels of life satisfaction. Participation in everyday occupations is related to life satisfaction even for caregivers of persons with stroke. The results of this study add to our knowledge about the stroke-caregiver dyad and will help to inform family-centred approaches within stroke rehabilitation.

  13. Can response-adaptive randomization increase participation in acute stroke trials? (United States)

    Tehranisa, Jason S; Meurer, William J


    A response-adaptive randomization (RAR) trial design actively adjusts the ratio of participants assigned to each trial arm, favoring the better performing treatment by using outcome data from participants already in the trial. Compared with a standard clinical trial, an RAR study design has the potential to improve patient participation in acute stroke trials. This cross-sectional randomized survey included adult emergency department patients, age≥18, without symptoms of stroke or other critical illness. A standardized protocol was used, and subjects were randomized to either an RAR or standard hypothetical acute stroke trial. After viewing the video describing the hypothetical trial (, reviewing the consent form, and having questions answered, subjects indicated whether they would consent to the trial. A multivariable logistic regression model was fitted to estimate the impact of RAR while controlling for demographic factors and patient understanding of the design. A total of 418 subjects (210 standard and 208 RAR) were enrolled. All baseline characteristics were balanced between groups. There was significantly higher participation in the RAR trial (67.3%) versus the standard trial (54.5%), absolute increase: 12.8% (95% confidence interval, 3.7-22.2). The RAR group had a higher odds ratio of agreeing to research (odds ratio, 1.89; 95% confidence interval, 1.2-2.9) while adjusting for patient level factors. Trial designs were generally well understood by the participants. The hypothetical RAR trial attracted more research participation than standard randomization. RAR has the potential to increase recruitment and offer benefit to future trial participants. © 2014 American Heart Association, Inc.

  14. Community-Based Rehabilitation to Improve Stroke Survivors' Rehabilitation Participation and Functional Recovery. (United States)

    Ru, Xiaojuan; Dai, Hong; Jiang, Bin; Li, Ninghua; Zhao, Xingquan; Hong, Zhen; He, Li; Wang, Wenzhi


    The aim of this study was to evaluate the effectiveness of a community-based rehabilitation appropriate technique (CRAT) intervention program in increasing rehabilitation participation and improving functional recovery of stroke survivors. This study followed a quasi-experimental design. In each of 5 centers servicing approximately 50,000 individuals, 2 communities were designated as either the intervention or control community. A CRAT intervention program, including 2-year rehabilitation education and 3-month CRAT treatment, was regularly implemented in the intervention communities, whereas there was no special intervention in the control community. Two sampling surveys, at baseline and after intervention, were administered to evaluate the rehabilitation activity undertaken. In intervention communities, stroke survivor's motor function, daily activity, and social activity were evaluated pretreatment and posttreatment, using the Fugl-Meyer Motor Function Assessment, Barthel index, and Social Functional Activities Questionnaire. The proportion of individuals participating in rehabilitation-related activity was increased significantly (P rehabilitation (P 0.05). Community-based rehabilitation appropriate technique increases rehabilitation participation rates and enhances motor function, daily activity, and social activity of stroke survivors.

  15. Barriers to activity and participation for stroke survivors in rural China. (United States)

    Zhang, Lifang; Yan, Tiebin; You, Liming; Li, Kun


    To investigate environmental barriers reported by stroke survivors in the rural areas of China and to determine the impact of environmental barriers on activity and participation relative to demographic characteristics and body functioning. Cross-sectional survey. Structured interviews in the participants' homes. Community-dwelling stroke survivors in the rural areas of China (N=639). Not applicable. Activity and participation (Chinese version of the World Health Organization Disability Assessment Schedule 2.0), environmental barriers (Craig Hospital Inventory of Environmental Factors), neurological function (Canadian Neurological Scale), cognitive function (Abbreviated Mental Test), and depression (6-item Hamilton Rating Scale for Depression). Physical/structural barriers are the major impediment to activity and participation for these participants (odds ratio, 1.86 and 1.99 for activity and participation, respectively; PChina. Attitudinal/support and policy barriers did not emerge as serious concerns. To generate an enabling environment, physical/structural and services/assistance barriers are the environmental barriers to be decreased and eliminated first.

  16. The Living with Dysarthria group for post-stroke dysarthria: the participant voice. (United States)

    Mackenzie, C; Kelly, S; Paton, G; Brady, M; Muir, M


    The Living with Dysarthria group programme, devised for people with post-stroke dysarthia and family members, was piloted twice. Feedback from those who experience an intervention contributes to the evaluation of speech and language therapy programmes, giving the participant view of the intervention's value and guiding further developments. What feedback do participants in the Living with Dysarthria programme provide, informing on its perceived usefulness and guiding its future development? Nine people with chronic dysarthria following stroke and four family members who completed the Living with Dysarthria programme all contributed to Focus Group (FG) discussion, transcribed and thematically analysed, and completed an Anonymous Questionnaire Evaluation (AQE), comprising closed statements and open questions. An anonymous descriptive adjective selection task (ADAST) was also used. The varied forms of feedback provided complementary information. Thematic analysis of FG data and AQE open question responses were configured around programme benefits, programme structure and content, and programme practicalities. Benefits associated with participation included learning and insight, being supported by peers and professionals, and improved speech and confidence. These are consistent with the main programme elements of education, support and speech practice. All activities were seen as relevant and positively received. Flexibility, recognition of and catering to individual needs were valued characteristics. The community location was approved by all. Most participants thought the format of eight weekly sessions of 2 h was appropriate. Responses to AQE closed statements provided almost unanimous confirmation of the very positive feedback conveyed in FG discussions. The main response to suggested improvements in AQEs was that the number of sessions should be increased. Feedback indicated that for a few individuals there was negative reaction to some facts about stroke, home

  18. Provision of inpatient rehabilitation and challenges experienced with participation post discharge: quantitative and qualitative inquiry of African stroke patients. (United States)

    Rhoda, Anthea; Cunningham, Natalie; Azaria, Simon; Urimubenshi, Gerard


    The provision of rehabilitation differs between developed and developing countries, this could impact on the outcomes of post stroke rehabilitation. The aim of this paper is to present provision of in-patient stroke rehabilitation. In addition the challenges experienced by the individuals with participation post discharge are also presented. Qualitative and quantitative research methods were used to collect data. The quantitative data was collected using a retrospective survey of stroke patients admitted to hospitals over a three- to five-year period. Quantitative data was captured on a validated data capture sheet and analysed descriptively. The qualitative data was collected using interviews from a purposively and conveniently selected sample, audio-taped and analysed thematically. The qualitative data was presented within the participation model. A total of 168 medical folders were reviewed for a South African sample, 139 for a Rwandan sample and 145 for a Tanzanian sample. The mean age ranged from 62.6 (13.78) years in the South African sample to 56.0 (17.4) in the Rwandan sample. While a total of 98 % of South African stroke patients received physiotherapy, only 39.4 % of Rwandan patients received physiotherapy. From the qualitative interviews, it became clear that the stroke patients had participation restrictions. When conceptualised within the Participation Model participation restrictions experienced by the stroke patients were a lack of accomplishment, inability to engage in previous roles and a perception of having health problems. With the exception of Rwanda, stroke patients in the countries studied are admitted to settings early post stroke allowing for implementation of effective acute interventions. The participants were experiencing challenges which included a lack of transport and the physical geographic surroundings in the rural settings not being conducive to wheelchair use. Stroke patients admitted to hospitals in certain African countries

  19. Experiences of participation in goal setting for people with stroke-induced aphasia in Norway. A qualitative study. (United States)

    Berg, Karianne; Askim, Torunn; Balandin, Susan; Armstrong, Elizabeth; Rise, Marit By


    The body of research into client participation in aphasia rehabilitation is increasing, but the evidence on how it is implemented into clinical practice is still scarce. Particularly, the importance of including the "insider's perspective" has been demanded. The aim of this study was to explore how people with aphasia experienced client participation during the process of goal setting and clinical decision making in language rehabilitation. Fifteen people with stroke-induced aphasia participated in semi-structured in-depth interviews. A qualitative analysis using Systematic Text Condensation was undertaken. Analysis revealed four main themes: (1) pleased with services, (2) vagueness in language rehabilitation, (3) personal goals exist, and (4) desired level of participation. Even though people with stroke-induced aphasia overall are pleased with the language rehabilitation, there is a need for greater emphasis on making the framework of language rehabilitation less vague. Therapists should also spend more time on collaboration with people with stroke-induced aphasia and use available methods to support communication and collaboration. The findings underscore the need for further exploration of the potential outcomes of implementing client participation in goal setting and clinical decision making for persons with stroke-induced aphasia. Implications for rehabilitation All persons with stroke induced aphasia should be asked about their goals for rehabilitation not only once, but during the whole continuum of their rehabilitation journey. Rehabilitation professionals should place greater emphasis on client participation by asking people with stroke induced aphasia how they prefer to participate at different stages of rehabilitation. To ensure active participation for those who wants it, existing tools and techniques which promoted collaborative goal setting should be better incorporated.

    Priyakorn Chaimongkol


    Full Text Available A clear retainer is a removable retainer that is popular in the present day. Compared with conventional fixed and removable orthodontic retainers, it is a more esthetic, comfortable, and inexpensive appliance. Although several studies have been published about clear retainers, it could be difficult to interpret the results because of the variety of study designs, sample sizes, and research methods. This article is intended to compile the content from previous studies and discuss advantages, disadvantages, fabrication, insertion, and adjustment. Moreover, the effectiveness in maintaining dental position, occlusion, retention protocols, thickness, and survival rate of clear retainers is discussed.

  1. Social participation following a stroke: an assessment in accordance with the international classification of functioning, disability and health. (United States)

    Silva, Soraia Micaela; Corrêa, João Carlos Ferrari; Pereira, Gabriela Santos; Corrêa, Fernanda Ishida


    Evaluate, code and qualify the participation of Brazilian stroke survivors based on the international classification of functioning, disability and health (ICF) and identify predictors of post-stroke participation. An exploratory, observational, cross-sectional study was conducted involving 78 individuals with hemiparesis stemming from a stroke. The stroke specific quality of life (SS-QOL) was used to evaluate the participation component of the ICF. The geriatric depression scale was used to screen depressive symptoms; the functional independence measure (FIM) was used to measure the degree of dependence; grip strength was determined using a dynamometer; and cognitive status was evaluated using the mini mental state examination. The one-way analysis of variance followed by the Bonferroni test was used for the comparison the participation scores of different groups (age and marital status). The independent t-test was used for the comparisons of the other groups (sex, time since the occurrence of stroke (12 months) and degree of functional independence). Multiple linear regression was employed to identify measures capable of predicting participation. Based on the classification and qualifiers of the ICF, the individuals analyzed exhibited a moderate level of participation. Participation was significantly associated with time since the occurrence of stroke (F = 2.46; 95% confidence interval (CI) = -23.67-0.34; p = 0.05), degree of functional independence (F = 2.40; 95% CI = -33.0 to -18.93; p participation (F = 99.2; r 2  = 0.57; p participation component of the ICF biopsychosocial model to be easily evaluated in clinical practice. Overall, the sample in the present study demonstrated a moderate decline in participation following a stroke and only the "social roles" domain was severely affected. The FIM was the main predictor of participation and the depression was a moderate predictor. Therefore, health professionals involved in the

These differences may be useful for identifying subjects with an ankle-brachial pressure index of blood pressure in both arms at the first visit. © 2018 American Heart Association, Inc.

  3. From physical and functional to continuity with pre-stroke self and participation in valued activities: a qualitative exploration of stroke survivors', carers' and physiotherapists' perceptions of physical activity after stroke. (United States)

    Morris, Jacqui H; Oliver, Tracey; Kroll, Thilo; Joice, Sara; Williams, Brian


    Physical activity (PA) improves fitness, functioning, health and wellbeing after stroke. However, many survivors are inactive. This study explored survivors', carers' and physiotherapists' beliefs about PA to identify how these support or hinder PA participation. Semi-structured in-depth interviews with community dwelling stroke survivors (n = 38); two focus groups involving six carers each; two focus groups, respectively, involving seven and eight stroke rehabilitation physiotherapists from clinical and community settings. Data were audio-recorded and transcribed. Analysis was structured using the Framework Approach to identify themes and a dynamic, conceptual model. Desired outcomes and control over outcome achievement were key concepts. For survivors and carers, PA supported participation in valued activities, providing continuity with pre-stroke sense of self. Carers adopted motivating strategies for PA to support recovery and participation in shared activities. In contrast, physiotherapists prioritised physical and functional outcomes and viewed survivors' control of outcomes as limited which was reflected by the support they provided. Individualised interventions that account for social and environmental influences on behaviour appear vital to enabling survivors to participate in meaningful physical activities. Such interventions should facilitate development of shared perspectives among physiotherapists, carers and survivors of PA and related outcomes and provide tailored strategies to facilitate PA participation. Implications for Rehabilitation Physical activity after stroke rehabilitation is important for fitness, health, functioning and well-being. Reasons for survivors participating or not in physical activity after stroke are complex and varied. Physiotherapists and carers influence survivors' participation in physical activity but their views about how to do this do not always match, or do they always complement the views of survivors.

    Full Text Available Background: Mobility impairments seen after Stroke impact walking speed, endurance and balance. Almost all the individuals with Stroke have fear of fall. The physical impairments in balance and gait along with individual’s perception about his/her own abilities to maintain balance might have an impact on level of activity and participation in the community. The association of these variables with recovery of Stroke has been well studied. However, it is currently unknown which of these variables are most associated with activity and participation in the community. This study aimed to identify the correlation of walking capacity and perception of fall with activity & participation. Methods: 30 Subjects were assessed for - walking capacity (6 minute walk test & Self-efficacy for falls (Modified Falls Efficacy scale. Level of Activity Limitation (AL & Participation Restriction (PR was graded on validated ICF Measure of Participation and Activities. (IMPACT-S Results: Data was analyzed using Pearson's correlation coefficient & regression model. Walking distance and Falls-efficacy is significantly correlated (r=-0.751 and -0.683, respectively with Participation restriction. Walking distance correlated with Activity Limitation (r=-0.714 significantly. Falls efficacy has a correlation coefficient of -0.642 with Activity Limitation. When put into Regression models, Walking Capacity & Gait Velocity was found to be independently associated with AL &PR. Conclusion: There is significant relationship between falls self-efficacy, walking capacity and Post-stroke activity & participation. Participation can be impacted by factors such as self-motivation and confidence about one's balance abilities. This is reflected by the correlation between falls efficacy and participation. Physical parameters such as the distance walked can contribute to participating in the community, and can predict variation in AL-PR

    Zhang, Lifang; Sui, Minghong; Yan, Tiebin; You, Liming; Li, Kun; Gao, Yan


    To explore the impacts of social participation and the environment on depression among people with stroke. Cross-sectional survey. Structured interviews in the participants' homes. Community-dwelling persons with stroke in the rural areas of China ( N = 639). Not applicable. Depression (Hamilton Rating Scale for Depression-6), activity and social participation (Chinese version of the World Health Organization's Disability Assessment Schedule 2.0), environmental barriers (Craig Hospital Inventory of Environmental Factors), neurological function (Canadian Neurological Scale). A total of 42% of the variance in depression was explained by the environmental barriers, neurological function, activity, and social participation factors studied. Social participation, services/assistance, and attitudes/support were directly related to depression; their standardized regression coefficients were 0.530, 0.162, and 0.092, respectively ( p ⩽ 0.01). The physical environment, policies, and neurological function indirectly impacted depression. Depression influences social participation in turn, with a standardized regression coefficient of 0.29 ( p ⩽ 0.01). Depression and social participation are inversely related. The physical environment, services/assistance, attitudes/support, and policies all impact post-stroke depression.

  8. The Right Supramarginal Gyrus Is Important for Proprioception in Healthy and Stroke-Affected Participants: A Functional MRI Study (United States)

    Ben-Shabat, Ettie; Matyas, Thomas A.; Pell, Gaby S.; Brodtmann, Amy; Carey, Leeanne M.


    Human proprioception is essential for motor control, yet its central processing is still debated. Previous studies of passive movements and illusory vibration have reported inconsistent activation patterns related to proprioception, particularly in high-order sensorimotor cortices. We investigated brain activation specific to proprioception, its laterality, and changes following stroke. Twelve healthy and three stroke-affected individuals with proprioceptive deficits participated. Proprioception was assessed clinically with the Wrist Position Sense Test, and participants underwent functional magnetic resonance imaging scanning. An event-related study design was used, where each proprioceptive stimulus of passive wrist movement was followed by a motor response of mirror ­copying with the other wrist. Left (LWP) and right (RWP) wrist proprioception were tested separately. Laterality indices (LIs) were calculated for the main cortical regions activated during proprioception. We found proprioception-related brain activation in high-order sensorimotor cortices in healthy participants especially in the supramarginal gyrus (SMG LWP z = 4.51, RWP z = 4.24) and the dorsal premotor cortex (PMd LWP z = 4.10, RWP z = 3.93). Right hemispheric dominance was observed in the SMG (LI LWP mean 0.41, SD 0.22; RWP 0.29, SD 0.20), and to a lesser degree in the PMd (LI LWP 0.34, SD 0.17; RWP 0.13, SD 0.25). In stroke-affected participants, the main difference in proprioception-related brain activation was reduced laterality in the right SMG. Our findings indicate that the SMG and PMd play a key role in proprioception probably due to their role in spatial processing and motor control, respectively. The findings from stroke-­affected individuals suggest that decreased right SMG function may be associated with decreased proprioception. We recommend that clinicians pay particular attention to the assessment and rehabilitation of proprioception following right hemispheric

    Full Text Available Aim. To investigate predictors of adherence to group-based exercise and physical activity participation among stroke survivors. Methods. 76 stroke survivors participated (mean age 66.7 years. Adherence was the percentage of classes attended over one year. Physical activity was the average pedometer steps/day measured over seven days at the end of the trial. Possible predictors included baseline measures of demographics, health, quality of life, falls, fear of falling, cognition, and physical functioning. Results. Mean class attendance was 60% (SD 29%. Only one variable (slow choice stepping reaction time was an independent predictor of higher class attendance, explaining 5% of the variance. Participants completed an average of 4,365 steps/day (SD 3350. Those with better physical functioning (choice stepping reaction time, postural sway, maximal balance range, 10-m walk, or 6-min walk or better quality of life (SF-12 score took more steps. A model including SF-12, maximal balance range, and 6-min walk accounted for 33% of the variance in average steps/day. Conclusions. The results suggest that better physical functioning and health status are predictors of average steps taken per day in stroke survivors and that predicting adherence to group exercise in this group is difficult.

  10. Reliability and validity of the L test in participants with chronic stroke. (United States)

    Kim, J S; Chu, D Y; Jeon, H S


    Many clinical mobility tests have been used for individuals who have suffered a stroke; however, the ceiling effect has been identified as a limitation for relatively high functioning individuals. The L test, a variation of the timed up and go test (TUG), was developed as a mobility test for patients after amputation. The objective of this study was to examine the reliability and validity of the L test among patients following a stroke. Cross-sectional. Rehabilitation hospital. Thirty-three chronic stroke survivors {20 males and 13 females, mean age 52.4 [standard deviation (SD) 11.2] years; mean time since stroke 29.1 (SD 13.3) months}. Not applicable. Validity was assessed by correlating the L test with other mobility tests (TUG, 10-m walk test and 2-minute walk test). Intra-class correlation coefficients (ICCs) were used to investigate reliability. The minimal detectable change (MDC) was used to determine true change. The L test was strongly correlated with the TUG test (r=0.887), and had excellent intra-rater (ICC3,1=0.99) and inter-rater reliability (ICC2,1=0.99). The MDC with a 95% confidence interval was 4seconds. The L test is a reliable, valid tool for evaluating gait in patients following a stroke. It is a more applicable method to assess individuals who are able to walk greater distances and have better gait in more functional situations. Copyright © 2014 Chartered Society of Physiotherapy.

  11. Development of a Questionnaire to Investigate Study Design Factors Influencing Participation in Gait Rehabilitation Research by People with Stroke: A Brief Report. (United States)

    Patterson, Kara K; Gallant, Nicole; Ormiston, Tracey; Patience, Chad; Whitechurch, Mandy; Mansfield, Avril; Brown, Janet


    The main objective of this study was to evaluate the feasibility of a newly developed questionnaire to assess the influence of study design on participation in gait rehabilitation research in a pilot test with individuals with stroke. A secondary objective was to investigate the relationship between participation in gait rehabilitation research and social and clinical factors of interest after stroke. A questionnaire was developed with expert opinion and guidance from related previous research. The questionnaire was pilot tested in a group of 21 people with stroke, and social and clinical factors (including gait function) were collected. Gait function was assessed using a pressure-sensitive mat; social and clinical characteristics were extracted from patient charts. Correlations were performed to investigate relationships between questionnaire responses and gait function, motor impairment, and chronicity; t-tests were used to examine response differences between people with a caregiver at home and those without. A total of 21 people with stroke completed the questionnaire without difficulty; mean completion time was 7.2 (SD 3.5) minutes, with a range of responses across participants. Borderline significant associations were found between gait function and the number of studies in which a person would participate and between stroke chronicity and the location of studies in which a person would participate. A questionnaire to investigate the influence of study design factors on participation in rehabilitation research is feasible for administration in the post-stroke population and has potential to inform the design of future studies.

  12. Virtual Reality to control active participation in a subacute stroke patient during robot-assisted gait training. (United States)

    Bergmann, J; Krewer, C; Müller, F; Koenig, A; Riener, R


    Virtual Reality (VR) provides a promising medium to enrich robot assisted rehabilitation. VR applications present the opportunity to engage patients in therapy and control participation. The aim of this study was to investigate two strategies to control active participation of a stroke patient focusing on the involvement of the paretic leg in task solution. A subacute stroke patient with a severe hemiparesis performed two experiments on the driven gait orthosis Lokomat. Patient activity was quantified by weighted interaction torques measured in both legs (experiment A) and the paretic leg only (experiment B). The patient was able to successfully implement both the bilateral and unilateral control modality. Both control modes increased the motor output of the paretic leg, however the paretic leg control mode resulted in a much more differentiated regulation of the activity in the leg. Both control modes are appropriate approaches to enhance active participation and increase motor output in the paretic leg. Further research should evaluate the therapeutic benefit of patients with hemiparesis using the unilateral control mode depending on the severity of their impairment. © 2011 IEEE

    Abzhandadze, Tamar; Forsberg-Wärleby, Gunilla; Holmegaard, Lukas; Redfors, Petra; Jern, Christina; Blomstrand, Christian; Jood, Katarina


    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. Cross-sectional, case-control study. Cohabitant spouses of survivors of ischaemic stroke aged 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. 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. 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.

    Concrete blocks retaining walls are commonly used for landscaping projects in which the retaining force strength of the structure is of paramount importance in preserving the integrity of the project and safety of humans and property. The effect of augmenting the retaining force strength of concrete block retaining walls was investigated using interlocking and interlocking with a horizontal steel re-bar and compared with regular concrete block walls. The average maximum retaining force for re...

  16. Trial participants' experiences of early enhanced speech and language therapy after stroke compared with employed visitor support: a qualitative study nested within a randomized controlled trial. (United States)

    Young, Alys; Gomersall, Timothy; Bowen, Audrey


    To explore trial participants' experiences of the process and outcomes of early, enhanced speech and language therapy after stroke with support from an employed visitor. Qualitative study nested within a randomized controlled trial. Twney-two people who, after stroke, had a diagnosis of aphasia (12), dysarthria (5) or both (5) and who participated in the ACT NoW study. Eight English NHS usual care settings. Individual interviews. Thematic content analysis assisted by a bespoke data transformation protocol for incorporating non-verbal and semantically ambiguous data. Participants highly regarded regular and sustained contact with someone outside of immediate family/friends who engaged them in deliberate activities/communication in the early months after stroke. Participants identified differences in the process of intervention between speech and language therapists and employed visitors. But no major discriminations were made between the impact or value of this contact according to whether provided by a speech and language therapist or employed visitor. Participant-defined criteria for effectiveness of contact included: impact on mood and confidence, self-recognition of progress and the meeting of individual needs. As in the randomized controlled trial, participants reported no evidence of added benefit of early communication therapy beyond that from attention control. The findings do not imply that regular contact with any non-professional can have beneficial effects for someone with aphasia or dysarthria in the early weeks following a stroke. The study points to specific conditions that would have to be met for contact to have a positive effect.

  18. From rehabilitation to recovery: protocol for a randomised controlled trial evaluating a goal-based intervention to reduce depression and facilitate participation post-stroke

    Directory of Open Access Journals (Sweden)

    Hill Keith


    Full Text Available Abstract Background There is much discourse in healthcare about the importance of client-centred rehabilitation, however in the realm of community-based therapy post-stroke there has been little investigation into the efficacy of goal-directed practice that reflects patients' valued activities. In addition, the effect of active involvement of carers in such a rehabilitation process and their subsequent contribution to functional and emotional recovery post-stroke is unclear. In community based rehabilitation, interventions based on patients' perceived needs may be more likely to alter such outcomes. In this paper, we describe the methodology of a randomised controlled trial of an integrated approach to facilitating patient goal achievement in the first year post-stroke. The effectiveness of this intervention in reducing the severity of post-stroke depression, improving participation status and health-related quality of life is examined. The impact on carers is also examined. Methods/Design Patients (and their primary carers, if available are randomly allocated to an intervention or control arm of the study. The intervention is multimodal and aims to screen for adverse stroke sequelae and address ways to enhance participation in patient-valued activities. Intervention methods include: telephone contacts, written information provision, home visitation, and contact with treating health professionals, with further relevant health service referrals as required. The control involves treatment as usual, as determined by inpatient and community rehabilitation treating teams. Formal blinded assessments are conducted at discharge from inpatient rehabilitation, and at six and twelve months post-stroke. The primary outcome is depression. Secondary outcome measures include participation and activity status, health-related quality of life, and self-efficacy.

  20. Older people's attitudes towards resuming driving in the first four months post-stroke. (United States)

    McNamara, Annabel; George, Stacey; Ratcliffe, Julie; Walker, Ruth


    Little is known about how older people recovering from stroke perceive their return to driving, particularly in the early stages of recovery when they may receive driving information. Semistructured interviews were conducted with 21 participants (52% female, mean age 74.5 years) within the first 16 weeks post-stroke, while inpatients in either acute or rehabilitation stroke wards. Interview data were analysed using content analysis. Three main themes emerged: 'driving as independence', 'emphasis on physical recovery', and 'limits on driving pre-stroke'. For the most part, driving was not a key consideration for participants during this phase of their recovery. Physical restrictions and confidence were seen as the main deterrent to driving post-stroke; however, this varied according to gender. Driving information is generally not retained in the first four weeks of recovery post-stroke. This has implications for the content and timing of driving information given post-stroke. © 2014 ACOTA.

  1. Reproducibility of the items on the Stroke Specific Quality of Life questionnaire that evaluate the participation component of the International Classification of Functioning, Disability and Health. (United States)

    Silva, Soraia Micaela; Corrêa, Fernanda Ishida; Faria, Christina Danielli Coelho de Morais; Pereira, Gabriela Santos; Attié, Edna Alves Dos Anjos; Corrêa, João Carlos Ferrari


    To evaluate the reproducibility of the Stroke Specific Quality of Life (SS-QOL) items that address the participation component of the International Classification of Functioning, Disability and Health (ICF) and analyse the correlation between the subscore of these 26 items and the total SS-QOL score. Seventy-five stroke survivors participated in this study. Reproducibility was evaluated using the intraclass correlation coefficient (ICC2,1), standard error of measurement (SEM), minimum detectable change (MDC) and the Bland-Altman plot. The correlation between the subscore of the 26 items and the total SS-QOL score was analysed using Spearman's correlation coefficients (rho) and simple linear regression. An alpha risk ≤ 0.05 was considered for all analyses. The SS-QOL items that address the participation component of the ICF demonstrated excellent reliability (intra-rater ICC2,1 = 0.96; inter-rater ICC2,1 = 0.95). The SEM and MDC were adequate. The Bland-Altman plot demonstrated satisfactory agreement. A significant and strong correlation (rho = 0.83) was found between the 26 SS-QOL items that address participation and the total SS-QOL score. Moreover, the evaluation of participation was found to explain 73% of the evaluation of health-related quality of life. The 26 SS-QOL items that address the participation component of the ICF demonstrated adequate reproducibility. Thus, participation, which represents the social aspects of functionality, can be adequately evaluated with these items. Implications for Rehabilitation The 26 Stroke Specific Quality of Life items that address participation proved to be reproducible for the analysis of social participation following a stroke. The findings can lead to a better understanding of the social participation of individuals with chronic hemiparesis and assist in the establishment of adequate treatment for such individuals. The rehabilitation process can be directed towards more specific goals focused on the

  2. Effects of Functional Limb Overloading on Symmetrical Weight Bearing, Walking Speed, Perceived Mobility, and Community Participation among Patients with Chronic Stroke

    Directory of Open Access Journals (Sweden)

    Sami S. Alabdulwahab


    Full Text Available Background. Stroke is a leading cause for long-term disability that often compromises the sensorimotor and gait function accompanied by spasticity. Gait abnormalities persist through the chronic stages of the condition and only a small percentage of these persons are able to walk functionally in the community. Material and Method. Patients with chronic stroke were recruited from outpatient rehabilitation unit at Department of Neurology & Neurosurgery, All India Institute of Medical Sciences, having a history of first stroke at least six months before recruitment, with unilateral motor deficits affecting gait. The patients were randomly assigned to either the functional limb overloading (FLO or Limb Overloading Resistance Training (LORT group and provided four weeks of training. Result. We found that there was an improvement in gait performance, weight bearing on affected limb, and perceived mobility and community participation. Conclusion. To the best of our knowledge, this is the first study that has evaluated the effects of functional limb overloading training on symmetric weight bearing, walking ability, and perceived mobility and participation in chronic hemiplegic population. The study demonstrated a beneficial effect of training on all the outcomes, suggesting that the functional limb overloading training can be a useful tool in the management of gait problems in chronic stroke patients.

  3. Effect of the provision of a cane on walking and social participation in individuals with stroke: protocol for a randomized trial. (United States)

    Avelino, Patrick Roberto; Nascimento, Lucas R; Menezes, Kênia K P; Scianni, Aline A; Ada, Louise; Teixeira-Salmela, Luci F

    Canes are usually prescribed for individuals with stroke with the purpose of improving walking and increasing safety. However, there is no consensus regarding the clinical effects of these aids on walking and participation. This study will examine the efficacy of the provision of a cane to improve walking and increase participation after stroke. This is a two-arm, prospectively registered, randomized trial with concealed allocation, blinded measurers, and intention-to-treat analysis. Fifty individuals with chronic stroke, categorized as slow or intermediate walkers (walking speeds ≤0.8m/s), will participate. The experimental group will receive a single-point cane and instructions to use the cane anytime they need to walk. The control group will receive a placebo intervention, consisting of self-stretching exercises of the lower limb muscles and instructions to not use assistive devices. The primary outcome will be comfortable walking speed. Secondary outcomes will include walking step length, walking cadence, walking capacity, walking confidence, and participation. Outcomes will be collected by a researcher blinded to group allocation at baseline (Week 0), after intervention (Week 4), and one month beyond intervention (Week 8). The provision of a single-point cane may help improving walking of slow and intermediate walkers after stroke. If walking is enhanced, the benefits may be carried over to participation, and individuals may experience greater free-living physical activity at home and in the community.

  6. 'Hip-hop' stroke: a stroke educational program for elementary school children living in a high-risk community. (United States)

    Williams, Olajide; Noble, James M


    Public stroke recognition is poor and poses a barrier to acute stroke treatment. We describe a stroke literacy program that teaches elementary school children in high-risk communities to recognize stroke and form an urgent action plan; we then present results of an intervention study using the program. "Hip-Hop" Stroke uses culturally and age-appropriate music and dance to enhance an interactive didactic curriculum including the FAST mnemonic (Facial droop, Arm weakness, Speech disturbance, Time to call 911). The program occurred in central Harlem, New York City, a community with high stroke risk. During the 2006 to 2007 school year, 582 fourth, fifth, and sixth graders (9 to 11 years of age) participated in 1-hour sessions over 3 consecutive days. Stroke knowledge was tested before and after the program with a 94% group participant retention. Students learned and retained knowledge well for stroke localization (20% correct before intervention, 93% correct immediately afterward, and 86% correct after 3-month delay; Phip-hop music may improve retention of stroke knowledge among the youth.

  7. Quantifying the risk of heart disease following acute ischaemic stroke: a meta-analysis of over 50 000 participants (United States)

    Gunnoo, Trishna; Hasan, Nazeeha; Khan, Muhammad Saleem; Slark, Julia; Bentley, Paul; Sharma, Pankaj


    Objective Following an acute stroke, there is a high risk of recurrence. However, the leading cause of mortality following a stroke is due to coronary artery disease (CAD) and myocardial infarction (MI) but that risk has not been robustly quantified. We sought to reliably quantify the risk of ischaemic heart disease (IHD) in patients presenting with acute ischaemic stroke (AIS) in the absence of a known cardiac history. Setting A meta-analysis study. PubMed, MEDLINE, EMBASE and Google Scholar were searched for potential studies up to October 2015. Included studies reported an acute cerebral ischaemic event and followed for CAD or MI within 1 year in patients without known IHD. Using arcsine transformed proportions for meta-analysis, studies were combined using a generic inverse variance random-effects model to calculate the pooled standardised mean difference and 95% CIs. These were interpreted as the percentage prevalence of CAD or incidence of MI following AIS. Results 17 studies with 4869 patients with AIS demonstrated a mean average of asymptomatic CAD in 52%. Anatomical methods of CAD detection revealed a prevalence of asymptomatic ≥50% coronary stenosis in 32% (95% CI 19% to 47%; pischaemic stroke revealed an overall risk of MI in the year following stroke of 3% (95% CI 1% to 5%; pischaemic stroke with no cardiac history have more than 50% coronary stenosis and 3% are at risk of developing MI within a year. Our findings provide a reliable quantitative measure of the risk of IHD following AIS in patients with no cardiac history. PMID:26792217

  9. Training in client-centeredness enhances occupational therapist documentation on goal setting and client participation in goal setting in the medical records of people with stroke (United States)

    Flink, Maria; Bertilsson, Ann-Sofie; Johansson, Ulla; Guidetti, Susanne; Tham, Kerstin; von Koch, Lena


    Objective: The aim of the present study was to compare client-centeredness as it was documented by the occupational therapists in the units randomized to the intervention clusters with documentation by occupational therapists in the control clusters. Design: Comparison of medical records. Setting: The study is conducted in a context of a randomized controlled trial in Sweden, with 16 post-stroke rehabilitation units cluster randomized to intervention or control group. Subjects: Occupational therapist documentation in medical records of 279 clients with stroke. Main measures: The medical records were reviewed for their level of client-centeredness using a protocol developed from the Stewart et al model. The occupational therapists in the intervention groups participated in a workshop training to enhance their client-centeredness. Results: Occupational therapists with training in client-centeredness documented significantly more on goal setting (OR = 4.1; 95% CI, 1.87-8.81), on client participation in goal setting (OR=11.34; 95% CI, 5.97-21.57), on how the goals could be reached (OR=2.8; 95% CI, 1.7-4.62), on client participation in how goals could be reached (OR=4.56; 95% CI, 2.73-7.64), on the follow-up on goals (OR=5.77; 95% CI, 2.78-11-98) and on client participation in follow-up on goals (OR=7.44, 95% CI, 4.33-12.8). This association remained after adjustment for healthcare setting, client socio-demographic variables, and stroke severity. Conclusion: Documentation of goal setting and client participation in goal setting can be influenced by training. PMID:26647421

  11. Postural control of individuals with chronic stroke compared to healthy participants: Timed-Up-and-Go, Functional Reach Test and center of pressure movement. (United States)

    Portnoy, Sigal; Reif, Shlomit; Mendelboim, Tom; Rand, Debbie


    Balance impairments are common following stroke, and may lead to loss of independent functional mobility and falls. Previous studies strived to come up with precise measures of postural control, which will provide a better prognostic power for the health status and safety of the individual. To date, the degree of difference in postural control measures between individuals with chronic stroke and healthy participants is not reported. Also there are no reported correlations between these measures and the Timed-Up-and-Go (TUG) and the Functional Reach Test (FRT). The aims of this study were: 1) to compare balance measures between young and older healthy participants and individuals with chronic stroke; 2) to assess correlations between TUG and FRT to center of pressure (COP) movements performed during four conditions; and 3) to determine the COP measures that best explain the variance in TUG and Functional Independence Measure (FIM). Cross-sectional study. Community. Thirteen young (mean±SD age 25.4±1.1), 11 older (mean±SD age 64.5± 3.5) healthy adults and 21 individuals 6-18 months post-stroke (mean±SD age 61.4 ±10.1). Measurements of COP were recorded while the subjects stood barefoot on a pressure-measuring pad during four conditions: FRT, quiet standing for 10s with eyes open and eyes closed, and sit-to-stand. The TUG was also administered. Participants filled the Activity-specific balance confidence scale (ABC), and their independence in basic activities was rated using the FIM. They also reported the number of falls since stroke onset. Between-group differences were significant. Moderate correlations between pressure-related measurements to the FRT and TUG were found. The COP path during sit-to-stand (Beta=0.971, Psit-to-stand (Beta=-0.789, Ptest scores. These measurements might shed more light on the postural control mechanisms in balance-impaired populations, therefore potentially improve the treatment of postural control.

    Grosmaire, Anne-Gaëlle; Duret, Christophe


    Repetitive, active movement-based training promotes brain plasticity and motor recovery after stroke. Robotic therapy provides highly repetitive therapy that reduces motor impairment. However, the effect of assist-as-needed algorithms on patient participation and movement quality is not known. To analyze patient participation and motor performance during highly repetitive assist-as-needed upper limb robotic therapy in a retrospective study. Sixteen patients with sub-acute stroke carried out a 16-session upper limb robotic training program combined with usual care. The Fugl-Meyer Assessment (FMA) score was evaluated pre and post training. Robotic assistance parameters and Performance measures were compared within and across sessions. Robotic assistance did not change within-session and decreased between sessions during the training program. Motor performance did not decrease within-session and improved between sessions. Velocity-related assistance parameters improved more quickly than accuracy-related parameters. An assist-as-needed-based upper limb robotic training provided intense and repetitive rehabilitation and promoted patient participation and motor performance, facilitating motor recovery.

We sought prospective studies with older (mean age ≥65 years community-dwelling populations in which the GDS was employed and subsequent stroke and/or CVD were recorded to provide individual participant data. Apathy symptoms were defined as the three apathy-related subitems of the GDS, with depressive symptoms the remaining items. We used myocardial infarction (MI, stroke, and all-cause mortality as main outcomes. Analyses were adjusted for age, sex, and MI/stroke history. An adaptation of the Newcastle–Ottawa scale was used to evaluate bias. Hazard ratios were calculated using one-stage random-effect Cox regression models.Results: Of the 52 eligible studies, 21 (40.4% were included, comprising 47,625 older people (mean age [standard deviation] 74 [7.4] years, over a median follow-up of 8.8 years.

    This study aimed to investigate the psychometric characteristics of reliability, validity and ability to detect change of a newly developed balance assessment tool, the Mini-BESTest, in Greek patients with stroke. A prospective, observational design study with test-retest measures was conducted. A convenience sample of 21 Greek patients with chronic stroke (14 male, 7 female; age of 63 ± 16 years) was recruited. Two independent examiners administered the scale, for the inter-rater reliability, twice within 10 days for the test-retest reliability. Bland Altman Analysis for repeated measures assessed the absolute reliability and the Standard Error of Measurement (SEM) and the Minimum Detectable Change at 95% confidence interval (MDC 95% ) were established. The Greek Mini-BESTest (Mini-BESTest GR ) was correlated with the Greek Berg Balance Scale (BBS GR ) for assessing the concurrent validity and with the Timed Up and Go (TUG), the Functional Reach Test (FRT) and the Greek Falls Efficacy Scale-International (FES-I GR ) for the convergent validity. The Mini-BESTestGR demonstrated excellent inter-rater reliability (ICC (95%CI) = 0.997 (0.995-0.999, SEM = 0.46) with the scores of two raters within the limits of agreement (mean dif  = -0.143 ± 0.727, p > 0.05) and test-retest reliability (ICC (95%CI) = 0.966 (0.926-0.988), SEM = 1.53). Additionally, the Mini-BESTest GR yielded very strong to moderate correlations with BBS GR (r = 0.924, p reliability and the equally good validity of the Mini-BESTest GR , strongly support its utility in Greek people with chronic stroke. Its ability to identify clinically meaningful changes and falls risk need further investigation.

  16. BPRA retainer design report

    International Nuclear Information System (INIS)


    The hydraulic and mechanical analyses and tests performed to demonstrate the acceptability of the retainer design are described. Side and top views of the retainer are shown. The design criteria for the retainer have been established on the basis of functional requirements and structural integrity. The functional aspects of the design were satisfied by ensuring that the retainer provides positive captured holddown on the BPRA to prevent motion. The structural integrity was confirmed through extensive static and dynamic analyses in which results were compared to conservative design limits and shown to be acceptable. The analytical parameters used and the conservatism of the dynamic flow analysis were further confirmed by prototype testing in air and under maximum flow conditions. The results of tests and analytical studies demonstrated that the retainer design is adequate for all conditions

    A 20-year-old woman attended a genitourinary clinic with a retained vaginal Mooncup that she had inserted the night before. A Mooncup is one type of menstrual cup. On speculum examination the device was visualized high in the vagina and the cervix appeared firmly lodged within it. The physician experienced difficulty in retrieving the cup despite following product instructions. This case highlights a new adverse event with an increasingly used sanitation product. It is important that clinicians are familiar with the cup, its removal process and are able to counsel patients with retained devices on future correct placement.

  4. Domiciliary VR-Based Therapy for Functional Recovery and Cortical Reorganization: Randomized Controlled Trial in Participants at the Chronic Stage Post Stroke. (United States)

    Ballester, Belén Rubio; Nirme, Jens; Camacho, Irene; Duarte, Esther; Rodríguez, Susana; Cuxart, Ampar; Duff, Armin; Verschure, Paul F M J


    Most stroke survivors continue to experience motor impairments even after hospital discharge. Virtual reality-based techniques have shown potential for rehabilitative training of these motor impairments. Here we assess the impact of at-home VR-based motor training on functional motor recovery, corticospinal excitability and cortical reorganization. The aim of this study was to identify the effects of home-based VR-based motor rehabilitation on (1) cortical reorganization, (2) corticospinal tract, and (3) functional recovery after stroke in comparison to home-based occupational therapy. We conducted a parallel-group, controlled trial to compare the effectiveness of domiciliary VR-based therapy with occupational therapy in inducing motor recovery of the upper extremities. A total of 35 participants with chronic stroke underwent 3 weeks of home-based treatment. A group of subjects was trained using a VR-based system for motor rehabilitation, while the control group followed a conventional therapy. Motor function was evaluated at baseline, after the intervention, and at 12-weeks follow-up. In a subgroup of subjects, we used Navigated Brain Stimulation (NBS) procedures to measure the effect of the interventions on corticospinal excitability and cortical reorganization. Results from the system's recordings and clinical evaluation showed significantly greater functional recovery for the experimental group when compared with the control group (1.53, SD 2.4 in Chedoke Arm and Hand Activity Inventory). However, functional improvements did not reach clinical significance. After the therapy, physiological measures obtained from a subgroup of subjects revealed an increased corticospinal excitability for distal muscles driven by the pathological hemisphere, that is, abductor pollicis brevis. We also observed a displacement of the centroid of the cortical map for each tested muscle in the damaged hemisphere, which strongly correlated with improvements in clinical scales. These

  6. Why do people lose their friends after a stroke? (United States)

    Northcott, Sarah; Hilari, Katerina


    It is well-known that people lose friends after a stroke; what is less well understood is why this occurs. This study explored why people lose contact with their friends, and whether there are any protective factors. It also examined how friendship loss and change is perceived by the individual. Participants with a first stroke were recruited from one acute stroke unit in the UK. In-depth qualitative interviews took place between 8 and 15 months post stroke. 29 participants were recruited of whom 10 had aphasia. The main reasons given for losing friends were: loss of shared activities, reduced energy levels, physical disability, aphasia, unhelpful responses of others, environmental barriers, and changing social desires. The subset of participants who experienced the most extensive loss of friends were those who described a sense that they were 'closing in' on themselves leading to a withdrawal from social contact and a new preference for meeting only close friends and family. Those with aphasia experienced the most hurtful negative responses from others and found it more difficult to retain their friends unless they had strong supportive friendship patterns prior to the stroke. The factors which helped to protect friendships included: having a shared history, friends who showed concern, who lived locally, where the friendship was not activity-based, and where the participant had a 'friends-based' social network prior to the stroke. Given the link between depression and loss of friends post stroke, supporting an individual in maintaining a social network is likely to be beneficial. For intervention to be effective, however, it may need to take into account not only the impact of new physical and language disabilities, but also changing social desires. © 2011 Royal College of Speech & Language Therapists.

  7. Child-Mediated Stroke Communication: findings from Hip Hop Stroke. (United States)

    Williams, Olajide; DeSorbo, Alexandra; Noble, James; Gerin, William


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

  8. Retained gas inventory comparison

    International Nuclear Information System (INIS)

    BARTON, W.B.


    Gas volume data derived from four different analytical methods were collected and analyzed for comparison to volumes originally used in the technical basis for the Basis for Interim Operations (BIO). The original volumes came from Hodgson (1996) listed in the reference section of this document. Hodgson (1996) screened all 177 single and double-shell tanks for the presence of trapped gas in waste via two analytical methods: Surface Level Rise (SLR), and Barometric Pressure Effect (BPE). More recent gas volume projections have been calculated using different analytical techniques along with updates to the parameters used as input to the SLR and BPE models. Gas volumes derived from new analytical instruments include those as measured by the Void Fraction Instrument (VFI) and Retained Gas Sampler (RGS). The results of this comparison demonstrate that the original retained gas volumes of Hodgson (1996) used as a technical basis in developing the BIO were conservative, and were conservative from a safety analysis standpoint. These results represent only comparisons to the original reported volumes using the limited set of newly acquired data that is available

  12. Participation of MCP-induced protein 1 in lipopolysaccharide preconditioning-induced ischemic stroke tolerance by regulating the expression of proinflammatory cytokines

    Directory of Open Access Journals (Sweden)

    Liang Jian


    Full Text Available Abstract Background Lipopolysaccharide (LPS preconditioning-induced neuroprotection is known to be related to suppression of the inflammatory response in the ischemic area. This study seeks to determine if monocyte chemotactic protein-induced protein 1 (MCPIP1, a recently identified CCCH Zn finger-containing protein, plays a role in focal brain ischemia and to elucidate the mechanisms of LPS-induced ischemic brain tolerance. Methods Transcription and expression of MCPIP1 gene was monitored by qRT-PCR and Western blot. Mouse microglia was prepared from cortices of C57BL/6 mouse brain and primary human microglia was acquired from Clonexpress, Inc. Wild type and MCPIP1 knockout mice were treated with LPS (0.2 mg/kg 24 hours before brain ischemia induced by transient middle cerebral artery occlusion (MCAO. The infarct was measured by 2,3,5-triphenyltetrazolium chloride (TTC staining. Results MCPIP1 protein and mRNA levels significantly increased in both mouse and human microglia and mouse brain undergoing LPS preconditioning. MCPIP1 mRNA level significantly increased in mice ipsilateral brain than that of contralateral side after MCAO. The mortality of MCPIP1 knockout mice was significantly higher than that of wild-type after MCAO. MCPIP1 deficiency caused significant increase in the infarct volume compared with wild type mice undergoing LPS preconditioning. MCPIP1 deficiency caused significant upregulation of proinflammatory cytokines in mouse brain. Furthermore, MCPIP1 deficiency increased c-Jun N terminal kinase (JNK activation substantially. Inhibition of JNK signaling decreased the production of proinflammatory cytokines in MCPIP1 knock out mice after MCAO. Conclusions Our data indicate that absence of MCPIP1 exacerbates ischemic brain damage by upregulation of proinflammatory cytokines and that MCPIP1 participates in LPS-induced ischemic stroke tolerance.

  15. Bonded retainers--clinical reliability. (United States)

    Segner, D; Heinrici, B


    Bonded retainers have become a very important retention appliance in orthodontic treatment. They are popular because they are considered reliable, independent of patient cooperation, highly efficient, easy to fabricate, and almost invisible. Of these traits, reliability is the subject of this clinical study. A total of 549 patients with retainers were analyzed with regard to wearing time, extension of the retainer, mean time between failures, operator, and age of patient. The average frequency of breakage or loss was 0.55 per retainer per year. This frequency was dependent primarily on the operator who bonded the retainer and on the extent of the retainer. If the upper canines were involved, reliability was lower. The majority of failures occurred during the first 3 to 6 months. The study showed that bonded retainers represent a highly efficient and reliable retention appliance suited to long-term use.

  16. Long-Term Effect of Participation in an Early Exercise and Education Program on Clinical Outcomes and Cost Implications, in Patients with TIA and Minor, Non-Disabling Stroke. (United States)

    Faulkner, James; Stoner, Lee; Lanford, Jeremy; Jolliffe, Evan; Mitchelmore, Andrew; Lambrick, Danielle


    Participation in exercise and education programs following transient ischemic attack (TIA) or minor stroke may decrease cardiovascular disease risk. The purpose of this study was to assess the long-term effect (3.5 years) of an exercise and education program administered soon after TIA or minor stroke diagnosis on clinical outcome measures (stroke classification and number, patient deaths, hospital/emergency department admission) and cost implications obtained from standard hospital records. Hospital records were screened for 60 adults (male, n = 31; 71 ± 10 years), diagnosed with TIA or non-disabling stroke, who had previously been randomised and completed either an 8-week exercise and education program, or usual care control. Follow-up clinical outcomes and cost implications were obtained 3.5 ± 0.3 years post-exercise. Participants randomised to the exercise and education program had significantly fewer recurrent stroke/TIAs (n = 3 vs. n = 13, Cohen's d = 0.79) than the control group (P ≤ 0.003). Similar finding were reported for patient deaths (n = 0 vs. n = 4, d = 0.53), and hospital admissions (n = 48 vs. n = 102, d = 0.54), although these findings were only approaching statistical significance. The relative risk (mean; 95%CI) of death, stroke/TIAs and hospital admissions were 0.11 (0.01 to 1.98), 0.23 (0.07 to 0.72) and 0.79 (0.57 to 1.09), respectively. Hospital admission costs were significantly lower for the exercise group ($9041 ± 15,080 NZD [~$6000 ± 10,000 USD]) than the control group ($21,750 ± 22,973 NZD [~$14,000 ± 15,000 USD]) during the follow-up period (P exercise and education programs for patients with TIA and minor stroke.

    There are limited data on the potential association of adherence to Mediterranean diet (MeD) with incident stroke. We sought to assess the longitudinal association between greater adherence to MeD and risk of incident stroke. We prospectively evaluated a population-based cohort of 30 239 individuals enrolled in REasons for Geographic and Racial Differences in Stroke (REGARDS) study, after excluding participants with stroke history, missing demographic data or food frequency questionnaires, and unavailable follow-up information. Adherence to MeD was categorized using MeD score. Incident stroke was adjudicated by expert panel review of medical records during a mean follow-up period of 6.5 years. Incident stroke was identified in 565 participants (2.8%; 497 and 68 cases of ischemic stroke [IS] and hemorrhagic stroke, respectively) of 20 197 individuals fulfilling the inclusion criteria. High adherence to MeD (MeD score, 5-9) was associated with lower risk of incident IS in unadjusted analyses (hazard ratio, 0.83; 95% confidence interval, 0.70-1.00; P=0.046). The former association retained its significance (hazard ratio, 0.79; 95% confidence interval, 0.65-0.96; P=0.016) after adjustment for demographics, vascular risk factors, blood pressure levels, and antihypertensive medications. When MeD was evaluated as a continuous variable, a 1-point increase in MeD score was independently associated with a 5% reduction in the risk of incident IS (95% confidence interval, 0-11%). We documented no association of adherence to MeD with incident hemorrhagic stroke. There was no interaction of race (P=0.37) on the association of adherence to MeD with incident IS. High adherence to MeD seems to be associated with a lower risk of incident IS independent of potential confounders. Adherence to MeD is not related to the risk of incident hemorrhagic stroke. © 2015 American Heart Association, Inc.

  3. Cryptogenic Stroke

    Directory of Open Access Journals (Sweden)

    Mohammad Saadatnia


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

  4. How to improve walking, balance and social participation following stroke: a comparison of the long term effects of two walking aids--canes and an orthosis TheraTogs--on the recovery of gait following acute stroke. A study protocol for a multi-centre, single blind, randomised control trial

    Directory of Open Access Journals (Sweden)

    Maguire Clare


    Full Text Available Abstract Background Annually, some 9000 people in Switzerland suffer a first time stroke. Of these 60% are left with moderate to severe walking disability. Evidence shows that rehabilitation techniques which emphasise activity of the hemiplegic side increase ipsilesional cortical plasticity and improve functional outcomes. Canes are commonly used in gait rehabilitation although they significantly reduce hemiplegic muscle activity. We have shown that an orthosis "TheraTogs" (a corset with elasticated strapping significantly increases hemiplegic muscle activity during gait. The aim of the present study is to investigate the long term effects on the recovery of gait, balance and social participation of gait rehabilitation with TheraTogs compared to gait rehabilitation with a cane following first time acute stroke. Methods/Design Multi-centre, single blind, randomised trial with 120 patients after first stroke. When subjects have reached Functional Ambulation Category 3 they will be randomly allocated into TheraTogs or cane group. TheraTogs will be applied to support hip extensor and abductor musculature according to a standardised procedure. Cane walking held at the level of the radial styloid of the sound wrist. Subjects will walk throughout the day with only the assigned walking aid. Standard therapy treatments and usual care will remain unchanged and documented.

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

  6. Differences in the role of black race and stroke risk factors for first vs recurrent stroke (United States)

    Kissela, Brett M.; Kleindorfer, Dawn O.; McClure, Leslie A.; Soliman, Elsayed Z.; Judd, Suzanne E.; Rhodes, J. David; Cushman, Mary; Moy, Claudia S.; Sands, Kara A.; Howard, Virginia J.


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

  8. Guideline Implementation: Prevention of Retained Surgical Items. (United States)

    Fencl, Jennifer L


    A surgical item unintentionally retained in a patient after an operative or other invasive procedure is a serious, preventable medical error with the potential to cause the patient great harm. Perioperative RNs play a key role in preventing retained surgical items (RSIs). The updated AORN "Guideline for prevention of retained surgical items" provides guidance for implementing a consistent, multidisciplinary approach to RSI prevention; accounting for surgical items; preventing retention of device fragments; reconciling count discrepancies; and using adjunct technologies to supplement manual count procedures. This article focuses on key points of the guideline to help perioperative personnel provide optimal care during a procedure. Key points addressed include taking responsibility for RSI prevention as a team; minimizing distractions, noise, and interruptions during counts; using consistent counting methods; reconciling discrepancies; and participating in performance-improvement activities. Perioperative RNs should review the complete guideline for additional information and for guidance in writing and updating policies and procedures. Copyright © 2016 AORN, Inc.

  10. Effects of Concurrent Depressive Symptoms and Perceived Stress on Cardiovascular Risk in Low- and High-Income Participants: Findings From the Reasons for Geographical and Racial Differences in Stroke (REGARDS) Study. (United States)

    Sumner, Jennifer A; Khodneva, Yulia; Muntner, Paul; Redmond, Nicole; Lewis, Marquita W; Davidson, Karina W; Edmondson, Donald; Richman, Joshua; Safford, Monika M


    Psychosocial risk for cardiovascular disease (CVD) may be especially deleterious in persons with low socioeconomic status. Most work has focused on psychosocial factors individually, but emerging research suggests that the confluence of psychosocial risk may be particularly harmful. Using data from the Reasons for Geographical and Racial Differences in Stroke (REGARDS) study, we examined associations among depressive symptoms and stress, alone and in combination, and incident CVD and all-cause mortality as a function of socioeconomic status. At baseline, 22 658 participants without a history of CVD (58.8% female, 41.7% black, mean age 63.9±9.3 years) reported on depressive symptoms, stress, annual household income, and education. Participants were classified into 1 of 3 psychosocial risk groups at baseline: (1) neither depressive symptoms nor stress, (2) either depressive symptoms or stress, or (3) both depressive symptoms and stress. Cox proportional hazards models were used to predict physician-adjudicated incident total CVD events (nonfatal myocardial infarction, nonfatal stroke, and cardiovascular death) and all-cause mortality over a median of 7.0 years (interquartile range 5.4-8.3 years) of follow-up. In fully adjusted models, participants with both depressive symptoms and stress had the greatest elevation in risk of developing total CVD (hazard ratio 1.48, 95% CI 1.21-1.81) and all-cause mortality (hazard ratio 1.33, 95% CI 1.13-1.56) but only for those with low income (<$35 000) and not high (≥$35 000) income. This pattern of results was not observed in models stratified by education. Findings suggest that screening for a combination of elevated depressive symptoms and stress in low-income persons may help identify those at increased risk of incident CVD and mortality. © 2016 The Authors.

  11. Intravenous HOE-642 reduces brain edema and Na uptake in the rat permanent middle cerebral artery occlusion model of stroke: evidence for participation of the blood-brain barrier Na/H exchanger. (United States)

    O'Donnell, Martha E; Chen, Yi-Je; Lam, Tina I; Taylor, Kelleen C; Walton, Jeffrey H; Anderson, Steven E


    Cerebral edema forms in the early hours of ischemic stroke by processes involving increased transport of Na and Cl from blood into brain across an intact blood-brain barrier (BBB). Our previous studies provided evidence that the BBB Na-K-Cl cotransporter is stimulated by the ischemic factors hypoxia, aglycemia, and arginine vasopressin (AVP), and that inhibition of the cotransporter by intravenous bumetanide greatly reduces edema and infarct in rats subjected to permanent middle cerebral artery occlusion (pMCAO). More recently, we showed that BBB Na/H exchanger activity is also stimulated by hypoxia, aglycemia, and AVP. The present study was conducted to further investigate the possibility that a BBB Na/H exchanger also participates in edema formation during ischemic stroke. Sprague-Dawley rats were subjected to pMCAO and then brain edema and Na content assessed by magnetic resonance imaging diffusion-weighed imaging and magnetic resonance spectroscopy Na spectroscopy, respectively, for up to 210 minutes. We found that intravenous administration of the specific Na/H exchange inhibitor HOE-642 significantly decreased brain Na uptake and reduced cerebral edema, brain swelling, and infarct volume. These findings support the hypothesis that edema formation and brain Na uptake during the early hours of cerebral ischemia involve BBB Na/H exchanger activity as well as Na-K-Cl cotransporter activity.

    Gualniera, Patrizia; Scurria, Serena


    Retained surgical sponge events continue to occur despite the implementation of preventive surgical count policies, procedures, and adjunct technologies to manual counting. Such intraoperative mistakes can cause chronic nonspecific symptoms during the early postoperative period. When discovered years after surgery, they raise thorny medicolegal questions. We describe two cases from our practice that illustrate the need to identify the responsibility of the surgical team, as delineated in ministerial directives and the current legal framework, as well as the difficulty in evaluating clinical actions taken at different times and in different settings, with regard to the permanent health damage incurred by sponge retention. Finally, we discuss prevention actions operating room staff should take to reduce the risk of retained surgical sponges. Copyright © 2018 Elsevier B.V. All rights reserved.

  17. Evaluating a community-based stroke nursing education and rehabilitation programme for patients with mild stroke. (United States)

    Wang, Lee; Chen, Chiu-Mei; Liao, Wen-Chun; Hsiao, Chun-Yin


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

  20. The functional magnetic resonance imaging (fMRI) procedure as experienced by healthy participants and stroke patients – A pilot study

    International Nuclear Information System (INIS)

    Szameitat, André J; Shen, Shan; Sterr, Annette


    An important aspect in functional imaging research employing magnetic resonance imaging (MRI) is how participants perceive the MRI scanning itself. For instance, the knowledge of how (un)comfortable MRI scanning is perceived may help institutional review boards (IRBs) or ethics committees to decide on the approval of a study, or researchers to design their experiments. We provide empirical data from our lab gained from 70 neurologically healthy mainly student subjects and from 22 mainly elderly patients suffering from motor deficits after brain damage. All participants took part in various basic research fMRI studies using a 3T MRI scanner. Directly after the scanning, all participants completed a questionnaire assessing their experience with the fMRI procedure. 87.2% of the healthy subjects and 77.3% of the patients rated the MRI procedure as acceptable to comfortable. In healthy subjects, males found the procedure more comfortable, while the opposite was true for patients. 12.1% of healthy subjects considered scanning durations between 30 and 60 min as too long, while no patient considered their 30 min scanning interval as too long. 93.4% of the healthy subjects would like to participate in an fMRI study again, with a significantly lower rate for the subjects who considered the scanning as too long. Further factors, such as inclusion of a diffusion tensor imaging (DTI) scan, age, and study duration had no effect on the questionnaire responses. Of the few negative comments, the main issues were noise, the restriction to keep still for the whole time, and occasional feelings of dizziness. MRI scanning in the basic research setting is an acceptable procedure for elderly and patient participants as well as young healthy subjects

    This evidence-based review examined the evidence supporting the use of occupation-based interventions to improve areas of occupation and social participation poststroke. A total of 39 studies met the inclusion criteria and were critically evaluated. Most of the literature targeted activity of daily living (ADL)–based interventions and collectively provided strong evidence for the use of occupation-based interventions to improve ADL performance. The evidence related to instrumental ADLs was much more disparate, with limited evidence to support the use of virtual reality interventions and emerging evidence to support driver education programs to improve occupational performance poststroke. Only 6 studies addressed leisure, social participation, or rest and sleep, with sufficient evidence to support only leisure-based interventions. The implications of this review for research, education, and practice in occupational therapy are also discussed. PMID:25553745

    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.

  13. Self-Reported Stroke Risk Stratification: Reasons for Geographic and Racial Differences in Stroke Study. (United States)

    Howard, George; McClure, Leslie A; Moy, Claudia S; Howard, Virginia J; Judd, Suzanne E; Yuan, Ya; Long, D Leann; Muntner, Paul; Safford, Monika M; Kleindorfer, Dawn O


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

  17. Cognitive performance after ischaemic stroke

    Directory of Open Access Journals (Sweden)

    Maria Gabriela R. Ferreira

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

  18. Federal Aviation Administration retained savings program proposal

    International Nuclear Information System (INIS)

    Hostick, D.J.; Larson, L.L.; Hostick, C.J.


    Federal legislation allows federal agencies to retain up to 50% of the savings associated with implementing energy efficiency and water conservation measures and practices. Given budget pressures to reduce expenditures, the use of retained savings to fund additional projects represents a source of funds outside of the traditional budget cycle. The Southwest Region Federal Aviation Administration (FAA) has tasked Pacific Northwest National Laboratory (PNNL) to develop a model retained savings program for Southwest Region FAA use and as a prototype for consideration by the FAA. PNNL recommends the following steps be taken in developing a Southwest Region FAA retained savings program: Establish a retained savings mechanism. Determine the level at which the retained savings should be consolidated into a fund. The preliminary recommendation is to establish a revolving efficiency loan fund at the regional level. Such a mechanism allows some consolidation of savings to fund larger projects, while maintaining a sense of facility ownership in that the funds will remain within the region

  19. Reducing recurrent stroke: methodology of the motivational interviewing in stroke (MIST) randomized clinical trial. (United States)

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

  20. Prostaglandins for management of retained placenta. (United States)

    Grillo-Ardila, Carlos F; Ruiz-Parra, Ariel I; Gaitán, Hernando G; Rodriguez-Malagon, Nelcy


    Retained placenta affects 0.5% to 3% of women following delivery and it is a major cause of maternal death due to postpartum haemorrhage. Usually, retained placenta has been managed by manual removal or curettage under anaesthesia, which may be associated with haemorrhage, infection and uterine perforation. Medical management to facilitate the delivery of the retained placenta could be a safe alternative avoiding surgical intervention. To assess the effectiveness and safety of prostaglandins for the management of retained placenta. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (1 December 2013), LILACS (1982 to 1 December 2013), SciELO (1998 to 1 December 2013), Web of Science (2001 to 1 December 2013), openSIGLE (1997 to 1 December 2013), World Health Organization International Clinical Trials Registry Platform (ICTRP) (1 December 2013) and the metaRegister of Controlled Trials (mRCT) (1 December 2013). We also contacted authors of included studies and reviewed the reference lists of retrieved studies. Randomised controlled clinical trials comparing the use of prostaglandins (or prostaglandin analogues) with placebo, expectant management, tocolytic drugs, any other prostaglandins or surgical interventions for the management of retained placenta after vaginal delivery of singleton live infants of 20 or more weeks of gestation. Two review authors independently assessed trials for inclusion and assessed trial quality. Two review authors independently extracted data. Data were checked for accuracy. Any disagreements were resolved through consensus or consultation with a third review author when required. Authors of the included studies were contacted for additional information. We included three trials, involving 244 women. The studies were considered to be at high risk of bias.The prostaglandins used were PG E2 analogue (sulprostone) in 50 participants and PG E1 analogue (misoprostol) in 194 participants at a dose of 250 mcg and 800 mcg

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

  13. Motor Imagery Impairment in Postacute Stroke Patients

    Directory of Open Access Journals (Sweden)

    Niclas Braun


    Full Text Available Not much is known about how well stroke patients are able to perform motor imagery (MI and which MI abilities are preserved after stroke. We therefore applied three different MI tasks (one mental chronometry task, one mental rotation task, and one EEG-based neurofeedback task to a sample of postacute stroke patients (n=20 and age-matched healthy controls (n=20 for addressing the following questions: First, which of the MI tasks indicate impairment in stroke patients and are impairments restricted to the paretic side? Second, is there a relationship between MI impairment and sensory loss or paresis severity? And third, do the results of the different MI tasks converge? Significant differences between the stroke and control groups were found in all three MI tasks. However, only the mental chronometry task and EEG analysis revealed paresis side-specific effects. Moreover, sensitivity loss contributed to a performance drop in the mental rotation task. The findings indicate that although MI abilities may be impaired after stroke, most patients retain their ability for MI EEG-based neurofeedback. Interestingly, performance in the different MI measures did not strongly correlate, neither in stroke patients nor in healthy controls. We conclude that one MI measure is not sufficient to fully assess an individual’s MI abilities.

  14. Retaining volunteers in volunteer computing projects. (United States)

    Darch, Peter; Carusi, Annamaria


    Volunteer computing projects (VCPs) have been set up by groups of scientists to recruit members of the public who are asked to donate spare capacity on their personal computers to the processing of scientific data or computationally intensive models. VCPs serve two purposes: to acquire significant computing capacity and to educate the public about science. A particular challenge for these scientists is the retention of volunteers as there is a very high drop-out rate. This paper develops recommendations for scientists and software engineers setting up or running VCPs regarding which strategies to pursue in order to improve volunteer retention rates. These recommendations are based on a qualitative study of volunteers in a VCP ( A typology of volunteers has been developed, and three particularly important classes of volunteers are presented in this paper: for each type of volunteer, the particular benefits they offer to a project are described, and their motivations for continued participation in a VCP are identified and linked to particular strategies. In this way, those setting up a VCP can identify which types of volunteers they should be particularly keen to retain, and can then find recommendations to increase the retention rates of their target volunteers.

  17. Stroke rehabilitation. (United States)

    Langhorne, Peter; Bernhardt, Julie; Kwakkel, Gert


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

  19. Identification of stroke during the emergency call: a descriptive study of callers' presentation of stroke. (United States)

    Berglund, Annika; von Euler, Mia; Schenck-Gustafsson, Karin; Castrén, Maaret; Bohm, Katarina


    To evaluate symptoms presented by the caller during emergency calls regarding stroke, and to assess if symptoms in the Face-Arm-Speech-Time Test (FAST) are related to identification of stroke. Emergency calls to the Emergency Medical Communication Center (EMCC) concerning patients discharged with stroke diagnosis in a large teaching hospital in Stockholm, Sweden, in January-June 2011. The emergency calls of 179 patients who arrived at hospital by ambulance, and who were discharged with a stroke diagnosis and consented to participate were included in the study. Frequencies of stroke symptoms presented and a comparison of symptoms presented in calls with dispatch code stroke or other dispatch code. Of the 179 emergency calls analysed, 64% were dispatched as 'Stroke'. FAST symptoms, that is, facial or arm weakness or speech disturbances, were presented in 64% of the calls and were spontaneously revealed in 90%. Speech disturbance was the most common problem (54%) in all calls, followed by fall/lying position (38%) and altered mental status (27%). For patients with dispatch codes other than stroke, the dominating problem presented was a fall or being in a lying position (66%), followed by speech disturbance (31%) and altered mental status (25%). Stroke-specific symptoms were more common in patients dispatched as stroke. FAST symptoms were reported in 80% of patients dispatched as stroke compared with 35% in those dispatched as something else. This study implicates that fall/lying position and altered mental status could be considered as possible symptoms of stroke during an emergency call. Checking for FAST symptoms in these patients might uncover stroke symptoms. Future studies are needed to evaluate if actively asking for FAST symptoms in emergency calls presenting falls or a lying position can improve the identification of stroke. Stroke2010/703-31/2.

  20. Hypothermia for Stroke: call to action 2010. (United States)

    Macleod, Malcolm R; Petersson, Jesper; Norrving, Bo; Hacke, Werner; Dirnagl, Ulrich; Wagner, Markus; Schwab, Stefan


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

  8. Early rehabilitation after stroke. (United States)

    Bernhardt, Julie; Godecke, Erin; Johnson, Liam; Langhorne, Peter


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

    Full Text Available Retaining walls are large category of engineering structures of multiple uses, having an essential safety ensuring role. The structural systems are varied because the situations and requirements derived from both site conditions and other criteria are varied. The paper enlarges upon retaining walls systems that use an outstanding amount of precast units and multiple cylindrical vault type structural systems supported by abutments [1], [2]. The paper proposes extending the structural system to retaining walls and develops certain specific issues. Some considerations regarding structural design are made.

  10. Early depressed mood after stroke predicts long-term disability: the Northern Manhattan Stroke Study (NOMASS). (United States)

    Willey, Joshua Z; Disla, Norbelina; Moon, Yeseon Park; Paik, Myunghee C; Sacco, Ralph L; Boden-Albala, Bernadette; Elkind, Mitchell S V; Wright, Clinton B


    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. 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 to 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. We fitted polytomous logistic regression models using a canonical link to examine the association between depressed mood after stroke and disability comparing moderate (Barthel Index 60 to 95) and severe (Barthel Index or=95). Cox proportional hazards models were created to examine the association between depressed mood and mortality. A question about depressed mood within 7 to 10 days after stroke was asked in 340 of 655 patients with ischemic stroke enrolled, and 139 reported that they felt depressed. In multivariate analyses controlling for sociodemographic factors, stroke severity, and medical conditions, depressed mood was associated with a greater odds of severe disability compared with no disability at 1 (OR 2.91, 95% CI 1.07 to 7.91) and 2 years (OR 3.72, 95% CI 1.29 to 10.71) after stroke. Depressed mood was not associated with all-cause mortality or vascular death. 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.

  11. Prevention Of Stroke

    Directory of Open Access Journals (Sweden)

    Nagaraja D


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

  12. Incidence of constipation in stroke patients (United States)

    Li, Jianxiang; Yuan, Mengguo; Liu, Yunfang; Zhao, Yang; Wang, Jingqing; Guo, Weifeng


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

  13. Acupuncture for acute stroke. (United States)

    Xu, Mangmang; Li, Dan; Zhang, Shihong


    acupuncture with sham acupuncture (SMD 0.01, 95% CI -0.55 to 0.57; low-quality evidence; and SMD 0.10, 95% CI -0.38 to 0.17; low-quality evidence, respectively).Trials comparing acupuncture with any control have reported little or no difference in death or institutional care at the end of follow-up (OR 0.78, 95% CI 0.54 to 1.12; five trials with 1120 participants; low-quality evidence), death within the first two weeks (OR 0.91, 95% CI 0.33 to 2.55; 18 trials with 1612 participants; low-quality evidence), or death at the end of follow-up (OR 1.08, 95% CI 0.74 to 1.58; 22 trials with 2865 participants; low-quality evidence).The incidence of adverse events (eg, pain, dizziness, faint) in the acupuncture arms of open and sham control trials was 6.2% (64/1037 participants), and 1.4% of these (14/1037 participants) discontinued acupuncture. When acupuncture was compared with sham acupuncture, findings for adverse events were uncertain (OR 0.58, 95% CI 0.29 to 1.16; five trials with 576 participants; low-quality evidence). This updated review indicates that apparently improved outcomes with acupuncture in acute stroke are confounded by the risk of bias related to use of open controls. Adverse events related to acupuncture were reported to be minor and usually did not result in stopping treatment. Future studies are needed to confirm or refute any effects of acupuncture in acute stroke. Trials should clearly report the method of randomization, concealment of allocation, and whether blinding of participants, personnel, and outcome assessors was achieved, while paying close attention to the effects of acupuncture on long-term functional outcomes.

    The aim of the Synergium was to devise and prioritize new ways of accelerating progress in reducing the risks, effects, and consequences of stroke. Preliminary work was performed by seven working groups of stroke leaders followed by a synergium (a forum for working synergistically together) with approximately 100 additional participants. The resulting draft document had further input from contributors outside the synergium. Recommendations of the Synergium are: Basic Science, Drug Development and Technology: There is a need to develop: (1) New systems of working together to break down the prevalent 'silo' mentality; (2) New models of vertically integrated basic, clinical, and epidemiological disciplines; and (3) Efficient methods of identifying other relevant areas of science.

    Full Text Available Time sensitive acute stroke treatments and the growing shortage of vascular neurologists compound to create a gap in the delivery of care to meet the American Stroke Association guidelines in underserviced regions. Audio/video consultation (telemedicine, which has been evolving since the late 1990's, is a putative solution. While telemedicine can serve as a valuable facilitative tool, the telestroke consultation is only one piece of a complex collaboration between hub and spoke environments and clinical personnel. The growing use of telemedicine in stroke offers more opportunities for all nurses to participate in the continuum of cerebrovascular disease care. A review of this collaboration will include but will not be limited to: algorithms of the acute stroke evaluation, hub and spoke staff meetings, stroke education for spoke staff, and patient follow–up post acute treatment. Our team's telemedicine experience, utilizing research, education, and clinical practice, will be described.

  3. Stroke survivors' endorsement of a "stress belief model" of stroke prevention predicts control of risk factors for recurrent stroke. (United States)

    Phillips, L Alison; Tuhrim, Stanley; Kronish, Ian M; Horowitz, Carol R


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

  7. Migration of innumerable chronically retained acupuncture needles

    Directory of Open Access Journals (Sweden)

    Frances Lazarow, MD


    Full Text Available We present a case of a 50-year-old female with a 2-day history of back and abdominal pain who was discovered to have innumerable chronically retained acupuncture needles, which had migrated throughout her abdomen and pelvis. Although many of these needles were in precarious positions, including the epidural space, renal parenchyma, small bowel, and vasculature, there was no evidence for acute injury. We also briefly discuss evidence for the magnetic resonance imaging compatibility of acupuncture needles. Although a rare complication, given the high frequency of acupuncture therapy in the United States, physicians must be aware of the potential for retained and migrated needles.

    Anderson, A M


    This case report describes a situation in which lack of milk production led the mother to seek help from a lactation consultant in private practice. Despite extensive breast stimulation with the baby at breast and mechanical breast expression, no milk was produced. Retained placenta was suspected by the lactation consultant. The mother was later diagnosed with placenta increta. Only when this condition was diagnosed and resolved did milk onset occur. It is important to evaluate for retained placental fragments when lactation appears to be delayed.

    This safety assessment addresses the proposed action to install, operate, and remove a Retained Gas Sampler (RGS) in Tank 101-SY at Hanford. Purpose of the RGS is to help characterize the gas species retained in the tank waste; the information will be used to refine models that predict the gas-producing behavior of the waste tank. The RGS will take samples of the tank from top to bottom; these samples will be analyzed for gas constituents. The proposed action is required as part of an evaluation of mitigation concepts for eliminating episodic gas releases that result in high hydrogen concentrations in the tank dome space.

    with previous stroke, there is a need for vigilance concerning individual experiences of stroke on sexuality to avoid under- or overestimating the impact and to raise the subject, which currently might be seldom. Individuals with long-term diverse consequences of stroke and with different sociodemographic backgrounds were interviewed. Because most individuals in the present study had retained functioning, this could decrease transferability to populations with more severe sequelae after stroke. The individuals in the present study had different experiences of sexuality after stroke. The results point to the importance of acknowledging sexual rehabilitation as part of holistic person-centered stroke rehabilitation. Nilsson MI, Fugl-Meyer K, von Koch L, Ytterberg C.

    Humaidan, Hani; Yassi, Nawaf; Weir, Louise; Davis, Stephen M; Meretoja, Atte


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

  13. International Survey on the Management of Wake-Up Stroke

    Directory of Open Access Journals (Sweden)

    Luís Henrique de Castro-Afonso


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

  14. Engaging and retaining abused women in perinatal home visitation programs. (United States)

    Sharps, Phyllis; Alhusen, Jeanne L; Bullock, Linda; Bhandari, Shreya; Ghazarian, Sharon; Udo, Ifeyinwa E; Campbell, Jacquelyn


    Intimate partner violence (IPV) during pregnancy affects 0.9% to 17% of women and affects maternal health significantly. The impact of IPV extends to the health of children, including an increased risk of complications during pregnancy and the neonatal period, mental health problems, and cognitive delays. Despite substantial sequelae, there is limited research substantiating best practices for engaging and retaining high-risk families in perinatal home visiting (HV) programs, which have been shown to improve infant development and reduce maltreatment. The Domestic Violence Enhanced Home Visitation Program (DOVE) is a multistate longitudinal study testing the effectiveness of a structured IPV intervention integrated into health department perinatal HV programs. The DOVE intervention, based on an empowerment model, combined 2 evidence-based interventions: a 10-minute brochure-based IPV intervention and nurse home visitation. Across all sites, 689 referrals were received from participating health departments. A total of 339 abused pregnant women were eligible for randomization; 42 women refused, and 239 women were randomly assigned (124 DOVE; 115 usual care), resulting in a 71% recruitment rate. Retention rates from baseline included 93% at delivery, 80% at 3 months, 76% at 6 months, and 72% at 12 months. Challenges for HV programs include identifying and retaining abused pregnant women in their programs. DOVE strategies for engaging and retaining abused pregnant women should be integrated into HV programs' federal government mandates for the appropriate identification and intervention of women and children exposed to IPV.

  20. Walking through Apertures in Individuals with Stroke.

    Directory of Open Access Journals (Sweden)

    Daisuke Muroi

    Full Text Available Walking through a narrow aperture requires unique postural configurations, i.e., body rotation in the yaw dimension. Stroke individuals may have difficulty performing the body rotations due to motor paralysis on one side of their body. The present study was therefore designed to investigate how successfully such individuals walk through apertures and how they perform body rotation behavior.Stroke fallers (n = 10, stroke non-fallers (n = 13, and healthy controls (n = 23 participated. In the main task, participants walked for 4 m and passed through apertures of various widths (0.9-1.3 times the participant's shoulder width. Accidental contact with the frame of an aperture and kinematic characteristics at the moment of aperture crossing were measured. Participants also performed a perceptual judgment task to measure the accuracy of their perceived aperture passability.Stroke fallers made frequent contacts on their paretic side; however, the contacts were not frequent when they penetrated apertures from their paretic side. Stroke fallers and non-fallers rotated their body with multiple steps, rather than a single step, to deal with their motor paralysis. Although the minimum passable width was greater for stroke fallers, the body rotation angle was comparable among groups. This suggests that frequent contact in stroke fallers was due to insufficient body rotation. The fact that there was no significant group difference in the perceived aperture passability suggested that contact occurred mainly due to locomotor factors rather than perceptual factors. Two possible explanations (availability of vision and/or attention were provided as to why accidental contact on the paretic side did not occur frequently when stroke fallers penetrated the apertures from their paretic side.

  1. The Impact of Pre-Stroke Depressive Symptoms, Fatalism, and Social Support on Disability after Stroke. (United States)

    Sharrief, Anjail Z; Sánchez, Brisa N; Lisabeth, Lynda D; Skolarus, Lesli E; Zahuranec, Darin B; Baek, Jonggyu; Garcia, Nelda; Case, Erin; Morgenstern, Lewis B


    Psychological and social factors have been linked to stroke mortality; however, their impact on stroke disability is unclear. The purpose of this study was to evaluate the impact of pre-stroke fatalism, depressive symptoms, and social support on 90-day neurologic, functional, and cognitive outcomes. Ischemic strokes (2008-2011) were identified from the Brain Attack Surveillance in Corpus Christi Project. Validated scales were used to assess fatalism, depressive symptoms, and social support during baseline interviews. The National Institutes of Health Stroke Scale, activities of daily living/instrumental activities of daily living (ADL/IADL) scale, and Modified Mini-Mental State Exam (3MSE) were used to assess 90-day outcomes. The associations between the pre-stroke variables and 90-day outcomes were estimated from regression models adjusting for demographics, risk factors, tissue-type plasminogen activator treatment, and comorbidities. Among 364 stroke survivors, higher pre-stroke fatalism was associated with worse functional (.17 point higher ADL/IADL per interquartile range [IQR] higher fatalism; 95% confidence interval [CI]: .05, .30) and cognitive (2.81 point lower 3MSE per IQR higher fatalism; 95% CI: .95, 4.67) outcomes. Higher pre-stroke depressive symptoms were associated with worse functional (.16 point higher ADL/IADL per IQR higher Patient Health Questionnaire-9; 95% CI: .04, .28) and cognitive (2.28 point lower 3MSE per IQR higher Patient Health Questionnaire-9; 95% CI: .46, 4.10) outcomes. Participants in the middle tertile of social support had better cognitive outcomes (3.75 points higher 3MSE; 95% CI: .93, 6.56) compared with the highest tertile. The associations between pre-stroke fatalism, depressive symptoms, and social support and 90-day outcomes suggest that psychosocial factors play an important role in stroke recovery.

  2. Piracetam for acute ischaemic stroke. (United States)

    Ricci, Stefano; Celani, Maria Grazia; Cantisani, Teresa Anna; Righetti, Enrico


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

  3. Ethnic differences in ischemic stroke subtypes in young-onset stroke: the Stroke Prevention in Young Adults Study. (United States)

    Trivedi, Megh M; Ryan, Kathleen A; Cole, John W


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

  4. Development of a Chronic Disease Management Program for Stroke Survivors Using Intervention Mapping: The Stroke Coach. (United States)

    Sakakibara, Brodie M; Lear, Scott A; Barr, Susan I; Benavente, Oscar; Goldsmith, Charlie H; Silverberg, Noah D; Yao, Jennifer; Eng, Janice J


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

  11. Auckland Stroke Outcomes Study. Part 1: Gender, stroke types, ethnicity, and functional outcomes 5 years poststroke. (United States)

    Feigin, V L; Barker-Collo, S; Parag, V; Senior, H; Lawes, C M M; Ratnasabapathy, Y; Glen, E


    Studying long-term stroke outcomes including body functioning (neurologic and neuropsychological impairments) and activity limitations and participation is essential for long-term evidence-based rehabilitation and service planning, resource allocation, and improving health outcomes in stroke. However, reliable data to address these issues is lacking. This study (February 2007-December 2008) sourced its participants from the population-based incidence study conducted in Auckland in 2002-2003. Participants completed structured self-administered questionnaires, and a face-to-face interview including a battery of neuropsychological tests. Logistic regression analysis was used to analyze associations between and within functional outcomes and their potential predictors. Of 418 5-year stroke survivors, two-thirds had good functional outcome in terms of neurologic impairment and disability (defined as modified Rankin Score <3), 22.5% had cognitive impairment indicative of dementia, 20% had experienced a recurrent stroke, almost 15% were institutionalized, and 29.6% had symptoms suggesting depression. Highly significant correlations were found between and within various measurements of body functioning (especially neuropsychological impairments), activity, and participation. Age, dependency, and depression were independently associated with most outcomes analyzed. The strong associations between neuropsychological impairment and other functional outcomes and across various measurements of body functioning, activity, and participation justify utilizing a multidisciplinary approach to studying and managing long-term stroke outcomes. Observed gender and ethnic differences in some important stroke outcomes warrant further investigations.

  12. Nursing care for stroke patients: A survey of current practice in 11 European countries. (United States)

    Tulek, Zeliha; Poulsen, Ingrid; Gillis, Katrin; Jönsson, Ann-Cathrin


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

  13. [Genetics of ischemic stroke]. (United States)

    Gschwendtner, A; Dichgans, M


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

  14. Hemorrhagic Stroke in Children


    Jordan M.D., Lori C.; Hillis M.D., Argye E.


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

  15. Motivational interviewing for improving recovery after stroke. (United States)

    Cheng, Daobin; Qu, Zhanli; Huang, Jianyi; Xiao, Yousheng; Luo, Hongye; Wang, Jin


    Psychological problems are common complications following stroke that can cause stroke survivors to lack the motivation to take part in activities of daily living. Motivational interviewing provides a specific way for enhancing intrinsic motivation, which may help to improve activities of daily living for stroke survivors. To investigate the effect of motivational interviewing for improving activities of daily living after stroke. We searched the Cochrane Stroke Group's Trials Register (November 2014), the Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 1), MEDLINE (1948 to March 2015), EMBASE (1980 to March 2015), CINAHL (1982 to March 2015), AMED (1985 to March 2015), PsycINFO (1806 to March 2015), PsycBITE (March 2015) and four Chinese databases. In an effort to identify further published, unpublished and ongoing trials, we searched ongoing trials registers and conference proceedings, checked reference lists, and contacted authors of relevant studies. Randomised controlled trials (RCTs) comparing motivational interviewing with no intervention, sham motivational interviewing or other psychological therapy for people with stroke were eligible. Two review authors independently selected studies for inclusion, extracted eligible data and assessed risk of bias. Outcome measures included activities of daily living, mood and death. One study involving a total of 411 participants, which compared motivational interviewing with usual care, met our inclusion criteria. The results of this review did not show significant differences between groups receiving motivational interviewing or usual stroke care for participants who were not dependent on others for activities of daily living, nor on the death rate after three-month and 12-month follow-up, but participants receiving motivational interviewing were more likely to have a normal mood than those who received usual care at three-months and 12-months follow-up. There is insufficient evidence to support

    Full Text Available An in situ full-scale test is conducted to measure the dynamic response of a long cantilever wall that retains backfill soil. The recorded modal parameters of this retaining wall exhibited significant similarity to those of a clamped cantilever plate (rather than those of a cantilever beam or plane-strain analysis. Such a three-dimensional (3-D response pattern is not accounted for by current analysis procedures. A simple 3-D finite element model is employed to further analyze the observed resonant configurations. The results indicate that such configurations play an important role in the seismic response of wall backfill soil systems of variable height, such as wing walls supporting highway approach ramps.

  17. ABO Blood Type and Stroke Risk: The REasons for Geographic and Racial Differences in Stroke (REGARDS) Study (United States)

    Zakai, Neil A.; Judd, Suzanne E.; Alexander, Kristine; McClure, Leslie A.; Kissela, Brett M.; Howard, George; Cushman, Mary


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

    Wu, Simiao


    Background Post-stroke fatigue (PSF) is a common and distressing problem after stroke. It impedes patients’ participation in daily activities and is associated with higher risks of institutionalisation and death following stroke. Despite its high prevalence and detrimental consequences, little research has been conducted to develop effective treatments for PSF. Psychological interventions are effective in treating fatigue in other conditions such as cancer and chronic fatigu...

  19. Tooth Retained Implant: No More an Oxymoron

    Directory of Open Access Journals (Sweden)

    Divya Bhat


    Full Text Available Introduction: Periodontally af-fected teeth are treated in one of the two ways. (1 Tooth retention after periodontal surgery, in which the degree of regeneration achieved is unpredictable. (2 Tooth extrac-tion and implant placement. Implants have an osseointegrated surface which does not provide adequate shock absorption. Regeneration can be achieved by resecting the crown of the affected tooth and submerging the root. This technique has not had a clinical application so far as the tooth becomes difficult to restore. Placing an implant within the root can make the retained root restorable. At the same time, as the implant is placed within the root surface it achieves a periodontal integration which dampens occlusal forces better than osseointegration. Therefore, such a “tooth retained implant” may serve as an additional treatment option with significant benefits over tooth retention and implant placement alone. The hypothesis: Implants placed within retained roots have shown cementum deposition and attachment of periodontal ligament fibers over their surface. This periodontal attachment may be able to dam-pen forces better than in an osseointegrated implant. Moreover, since an implant is being placed, the crown of the tooth can be resected and submerged. This prevents epithelial migration, allows for the periodontal ligament cells to populate the wound and favors regeneration.Evaluation of the hypothesis: The technique of placing implants within cavities prepared in the root and then submerging them are simple for any practitioner placing implants routinely.

    Established risk factors do not fully identify patients at risk for recurrent stroke. The SPARCL trial (Stroke Prevention by Aggressive Reduction in Cholesterol Levels) evaluated the effect of atorvastatin on stroke risk in patients with a recent stroke or transient ischemic attack and no known coronary heart disease. This analysis explored the relationships between 13 plasma biomarkers assessed at trial enrollment and the occurrence of outcome strokes. We conducted a case-cohort study of 2176 participants; 562 had outcome strokes and 1614 were selected randomly from those without outcome strokes. Time to stroke was evaluated by Cox proportional hazards models. There was no association between time to stroke and lipoprotein-associated phospholipase A 2 , monocyte chemoattractant protein-1, resistin, matrix metalloproteinase-9, N-terminal fragment of pro-B-type natriuretic peptide, soluble vascular cell adhesion molecule-1, soluble intercellular adhesion molecule-1, or soluble CD40 ligand. In adjusted analyses, osteopontin (hazard ratio per SD change, 1.362; P strokes. After adjustment for the Stroke Prognostic Instrument-II and treatment, osteopontin, neopterin, and myeloperoxidase remained independently associated with outcome strokes. The addition of these 3 biomarkers to Stroke Prognostic Instrument-II increased the area under the receiver operating characteristic curve by 0.023 ( P =0.015) and yielded a continuous net reclassification improvement (29.1%; P stroke and improved risk classification when added to a clinical risk algorithm.

    Srivastava Abhishek


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

  3. Social work after stroke: identifying demand for support by recording stroke patients' and carers' needs in different phases after stroke. (United States)

    Padberg, Inken; Knispel, Petra; Zöllner, Susanne; Sieveking, Meike; Schneider, Alice; Steinbrink, Jens; Heuschmann, Peter U; Wellwood, Ian; Meisel, Andreas


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

    Janssen, Heidi; Dunstan, David W; Bernhardt, Julie; Walker, Frederick R; Patterson, Amanda; Callister, Robin; Dunn, Ashlee; Spratt, Neil J; English, Coralie


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

  6. Stroke management: Informal caregivers' burdens and strians of caring for stroke survivors. (United States)

    Gbiri, Caleb Ademola; Olawale, Olajide Ayinla; Isaac, Sarah Oghenekewe


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

  8. Clinical Epidemiology Of Stroke

    Directory of Open Access Journals (Sweden)

    Nagaraja D


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

    BACKGROUND: The validity of the registration of patients in stroke-specific registries has seldom been investigated, nor compared with administrative hospital discharge registries. The objective of this study was to examine the validity of the registration of patients in a stroke-specific registry...... (The Danish Stroke Registry [DSR]) and a hospital discharge registry (The Danish National Patient Registry [DNRP]). METHODS: Assuming that all patients with stroke were registered in either the DSR, DNRP or both, we first identified a sample of 75 patients registered with stroke in 2009; 25 patients...... in the DSR, 25 patients in the DNRP, and 25 patients registered in both data sources. Using the medical record as a gold standard, we then estimated the sensitivity and positive predictive value of a stroke diagnosis in the DSR and the DNRP. Secondly, we reviewed 160 medical records for all potential stroke...

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

    Leisure activity participation has been shown to lower risks of cognitive decline in non-stroke populations. However, effects of leisure activities participation upon cognitive functions and risk of dementia after stroke are unclear. The purpose of this study is to examine the effects of recent past leisure activities participation upon cognitive functions and risk of incident dementia after stroke. Hospital-based, retrospective cohort study. 88 of 1,013 patients with stroke or TIA having no prestroke dementia were diagnosed to have incident poststroke dementia (PSD) 3-6 months after stroke. Regular participation (≥3 times per week) in intellectual, recreational, social and physical activities over the year before the index stroke was retrospectively recorded at 3-6 months after stroke. Logistic regression analyses showed that regular participation in intellectual (RR 0.36, 95%CI 0.20-0.63) and stretching & toning physical exercise (0.37, 0.21-0.64) was significantly associated with a reduced risk of PSD after controlling for age, education, prestroke cognitive decline, stroke subtype, prior strokes and chronic brain changes including white matter changes, old infarcts and global atrophy. Results were similar in patients with past strokes in unadjusted models. Participation in increased number of activities in general (r = 0.41, pleisure activities was associated with better poststroke cognitive performance. Findings of this retrospective cohort study call for studies of activity intervention for prevention of cognitive decline in individuals at elevated risk of stroke.

  15. Self Retaining Anti-Rotation Key (United States)

    Dixon, Alan Benjamin Christopher (Inventor)


    Anti-rotation keys are typically used in applications where an end of a threaded stud is received in a housing, and where the opposite end of the stud projects from the housing to allow attachment of another component to the housing. Once partially received in the housing, further rotation of the stud is prevented by an anti-rotation key. The disclosed anti-rotation key is self-retaining, in that it prevents itself from "backing out" of the channel due to vibration or thermal expansion of the housing, etc., while also being removable from the channel if desired.

    Valon A. Zejnullahu


    Full Text Available The problem of retained surgical bodies (RSB after surgery is an issue for surgeons, hospitals and the entire medical team. They have potentially harmful consequences for the patient as they can be life threatening and usually, a further operation is necessary. The incidence of RSB is between 0.3 to 1.0 per 1,000 abdominal operations, and they occur due to a lack of organisation and communication between surgical staff during the process. Typically, the RSB are surgical sponges and instruments located in the abdomen, retroperitoneum and pelvis.

    Álvarez-Velasco, Rodrigo; Masjuan, Jaime; DeFelipe, Alicia; Corral, Iñigo; Estévez-Fraga, Carlos; Crespo, Leticia; Alonso-Cánovas, Araceli


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

    Directory of Open Access Journals (Sweden)

    A Chitsaz


    Full Text Available Introduction: stroke in recreational substance users can be an indirect complication, like endocarditis and cardio embolism in parenteral drug users. With some drug like cocaine, stroke appear to be the result of a direct effect. In young subjects without other risk factors provide persuasive evidence for causality . OPIATES: Heroine is the most abused opiate drug, which is administered by injection, by snorting or by smoking. Stroke affects heroin users by diverse mechanisms,. Injectors are at risk of infections endocarditis, which carries risk for both ischemic and hemorrhagic stroke. Cerebral or subarachnoid hemorrhage usually occurs after rupture of a septic (mycotic aneurysm. Heroine users can are also at risk for hemorrhagic stroke secondary to liver failure with deranged clotting and to heroin nephropathy with uremia or malignant hypertension. In some heroin users the drug it self is directly causal due to vasculitis, hypersensitivity and immunologic changes. Embolization of foreign material to brain due to mixed of heroine with quinine can cause cerebral embolism.

    Danika Belliveau


    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.

    Vasculitis is a rare, but treatable condition that can present to hyperacute stroke units. Thrombolysis does not treat the underlying pathology, and a rapidly evolving clinical picture drives clinical decision often before all the investigation results are available.

  4. [The impact of personality traits on adolescents' adaptation and compliance to clear retainers]. (United States)

    Xu, Fan; Tang, Guo-Hua


    The aim of this study was to evaluate the adolescents' adaptation and compliance to clear retainers, and to investigate their associations with personality traits. Fifty adolescents at the end of fixed orthodontic treatment were consecutively recruited. After debonding the fixed orthodontic appliances, clear retainers were used. Participants were asked to fill questionnaires 2 months after wearing the clear retainers. A questionnaire was designed to evaluate their adaptation and compliance for clear retianers. Eysenck personality questionnaire was used to assess the personality traits. Spearman rank correlation was used to analyze the associations between personality traits with the adaptation and compliance to clear retainers using SAS8.0 software package. Forty-two of 50 adolescents accomplished the questionnaires. 76% felt no mucous irritation, 95% felt no influence on socializing. However, 75% showed oral constraint, 71% felt impaired speech. Moreover, 40% adolescents wore the retainers less than 18 hours per day. 31% patients had their aligner lost. 83% patients did not brush their teeth after each meal. Neuroticism was positively associated with the effect of impaired chewing (r=0.32). Psychoticism was positively associated with the oral constraint (r=0.31) and facial muscular soreness (r=0.35), but negatively associated with the influence on emotion (r=-0.34). Extraversion was positively associated with the retainers' damage (r=0.31). Adolescents showed good adaptation for clear retainers, but unsatisfactory compliance. There are associations between adolescents' adaptation and compliance for clear retainers and personality traits. These results suggest that clinicians should pay more attention to the compliance of adolescents when using clear retainer. Personality traits could be a useful prediction to assess the compliance for clear aligners.

    Full Text Available Objectives: Relapse of anterior open bite after treatment poses a challenge to orthodontists and warrants finding new methods. We aimed to compare the effect of a skeletal retention (SR system to the conventional retention (CR commonly used. Materials and Methods: Twenty patients participated in this study. SR group ten patients (five females and five males with mean age of 16.2 years, CR group ten patients (five females and five males with mean age of 17.1 years in pretreatment stage. The SR system is comprised of four self-drilling miniscrews and vacuum retainers with interarch elastics where the CR group is comprised of removable or fixed retainers. Pretreatment (T1, posttreatment (T2, and 1-year follow up (T3 lateral cephalograms were taken and analyzed to compare the stability of both retention modalities. Results: The overbite in the CR group showed more relapse in the form of significant reduction when compared to the SR group (P < 0.001. The overbite was reduced only by 0.1 mm (±0.3 in the SR group compared to 1.4 mm (±0.9 in the CR group. In the CR group, the upper incisors and first molar showed a more significant relapse compared to the SR group (P < 0.05. Conclusion: Skeletal retention using miniscrews and vertical elastic is an effective method for retention of anterior open bite cases.

  6. Changes in memory before and after stroke differ by age and sex, but not by race. (United States)

    Wang, Qianyi; Mejía-Guevara, Iván; Rist, Pamela M; Walter, Stefan; Capistrant, Benjamin D; Glymour, M Maria


    Post-stroke memory impairment is more common among older adults, women and blacks. It is unclear whether post-stroke differences reflect differential effects of stroke per se or differences in prestroke functioning. We compare memory trajectories before and after stroke by age, sex and race. Health and Retirement Study participants aged ≥50 years (n = 17,341), with no stroke history at baseline, were interviewed biennially up to 10 years for first self- or proxy-reported stroke (n = 1,574). Segmented linear regression models were used to compare annual rates of memory change before and after stroke among 1,169 stroke survivors, 405 stroke decedents and 15,767 stroke-free participants. Effect modification was evaluated with analyses stratified by baseline age (≤70 vs. >70), sex and race (white vs. nonwhite), and using interaction terms between age/sex/race indicators and annual memory change. Older (>70 years) adults experienced a faster memory decline before stroke (-0.19 vs. -0.10 points/year for survivors, -0.24 vs. -0.13 points/year for decedents, p memory decrements (-0.64 vs. -0.26 points, p memory decline (-0.15 vs. -0.07 points/year, p = 0.003) after stroke onset, compared to younger adults. Female stroke survivors experienced a faster prestroke memory decline than male stroke survivors (-0.14 vs. -0.10 points/year, p memory scores than nonwhites, race was not associated with rate of memory decline during any period of time; i.e. race did not significantly modify the rate of decline before or after stroke or the immediate effect of stroke on memory. Older age predicted worse memory change before, at and after stroke onset. Sex and race differences in post-stroke memory outcomes might be attributable to prestroke disparities, which may be unrelated to cerebrovascular disease. © 2014 S. Karger AG, Basel.

  8. Blood Pressure Control: Stroke and Stroke Prevention

    Directory of Open Access Journals (Sweden)

    Hans-Christoph Diener


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

  10. European Stroke Science Workshop (United States)

    Mattle, Heinrich P.; Brainin, Michael; Chamorro, Angel; Diener, Hans Christoph; Hacke, Werner; Leys, Didier; Norrving, Bo; Ward, Nick


    The European Stroke Organisation (ESO) held its first European Stroke Science Workshop in Garmisch-Partenkirchen, Germany (15-17 December 2011). Stroke experts based in Europe were invited to present and discuss their current research. The scope of the workshop was to review the most recent findings of selected topics in stroke, to exchange ideas, to stimulate new research and to enhance collaboration between European stroke research groups. Seven scientific sessions were held, each starting with a keynote lecture to review the state of the art of the given topic, followed by 4 or 5 short presentations by experts. They were asked to limit their presentations to 10 slides containing only recent information. The meeting was organized by the executive committee of the ESO (Heinrich Mattle, chairman, Michael Brainin, Angel Chamorro, Werner Hacke, Didier Leys) and supported by the European Stroke Conference (Michael Hennerici). In this article we summarize the main contents of this successful workshop. PMID:22836350

  11. Periodontal Disease, Regular Dental Care Use, and Incident Ischemic Stroke. (United States)

    Sen, Souvik; Giamberardino, Lauren D; Moss, Kevin; Morelli, Thiago; Rosamond, Wayne D; Gottesman, Rebecca F; Beck, James; Offenbacher, Steven


    Periodontal disease is independently associated with cardiovascular disease. Identification of periodontal disease as a risk factor for incident ischemic stroke raises the possibility that regular dental care utilization may reduce the stroke risk. In the ARIC (Atherosclerosis Risk in Communities) study, pattern of dental visits were classified as regular or episodic dental care users. In the ancillary dental ARIC study, selected subjects from ARIC underwent fullmouth periodontal measurements collected at 6 sites per tooth and classified into 7 periodontal profile classes (PPCs). In the ARIC study 10 362 stroke-free participants, 584 participants had incident ischemic strokes over a 15-year period. In the dental ARIC study, 6736 dentate subjects were assessed for periodontal disease status using PPC with a total of 299 incident ischemic strokes over the 15-year period. The 7 levels of PPC showed a trend toward an increased stroke risk (χ 2 trend P stroke/1000-person years was 1.29 for PPC-A (health), 2.82 for PPC-B, 4.80 for PPC-C, 3.81 for PPC-D, 3.50 for PPC-E, 4.78 for PPC-F, and 5.03 for PPC-G (severe periodontal disease). Periodontal disease was significantly associated with cardioembolic (hazard ratio, 2.6; 95% confidence interval, 1.2-5.6) and thrombotic (hazard ratio, 2.2; 95% confidence interval, 1.3-3.8) stroke subtypes. Regular dental care utilization was associated with lower adjusted stroke risk (hazard ratio, 0.77; 95% confidence interval, 0.63-0.94). We confirm an independent association between periodontal disease and incident stroke risk, particularly cardioembolic and thrombotic stroke subtype. Further, we report that regular dental care utilization may lower this risk for stroke. © 2018 American Heart Association, Inc.

  12. Challenges in building interpersonal care in organized hospital stroke units: The perspectives of stroke survivors, family caregivers and the multidisciplinary team. (United States)

    Ryan, Tony; Harrison, Madeleine; Gardiner, Clare; Jones, Amanda


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

  14. Design principles for engaging and retaining virtual citizen scientists. (United States)

    Wald, Dara M; Longo, Justin; Dobell, A R


    Citizen science initiatives encourage volunteer participants to collect and interpret data and contribute to formal scientific projects. The growth of virtual citizen science (VCS), facilitated through websites and mobile applications since the mid-2000s, has been driven by a combination of software innovations and mobile technologies, growing scientific data flows without commensurate increases in resources to handle them, and the desire of internet-connected participants to contribute to collective outputs. However, the increasing availability of internet-based activities requires individual VCS projects to compete for the attention of volunteers and promote their long-term retention. We examined program and platform design principles that might allow VCS initiatives to compete more effectively for volunteers, increase productivity of project participants, and retain contributors over time. We surveyed key personnel engaged in managing a sample of VCS projects to identify the principles and practices they pursued for these purposes and led a team in a heuristic evaluation of volunteer engagement, website or application usability, and participant retention. We received 40 completed survey responses (33% response rate) and completed a heuristic evaluation of 20 VCS program sites. The majority of the VCS programs focused on scientific outcomes, whereas the educational and social benefits of program participation, variables that are consistently ranked as important for volunteer engagement and retention, were incidental. Evaluators indicated usability, across most of the VCS program sites, was higher and less variable than the ratings for participant engagement and retention. In the context of growing competition for the attention of internet volunteers, increased attention to the motivations of virtual citizen scientists may help VCS programs sustain the necessary engagement and retention of their volunteers. © 2016 Society for Conservation Biology.

  15. Satisfaction with palliative care after stroke: a prospective cohort study. (United States)

    Blacquiere, Dylan; Bhimji, Khadija; Meggison, Hilary; Sinclair, John; Sharma, Michael


    The determinants of satisfaction for families of acute stroke patients receiving palliative care have not been extensively studied. We surveyed families to determine how they perceived palliative care after stroke. Families of patients palliated after ischemic stroke, intracerebral, or subarachnoid hemorrhage were approached. Four weeks after the patient's death, families were administered the After-Death Bereaved Family Member Interview to determine satisfaction with the care provided. Fifteen families participated. Families were most satisfied with participation in decision making and least satisfied with attention to emotional needs. In stroke-specific domains, families had less satisfaction with artificial feeding, hydration, and communication. Overall satisfaction was high (9.04 out of 10). Families of patients receiving palliative care at our institution showed generally high satisfaction with palliation after stroke; specific domains were identified for improvement. Further study in larger populations is required.

  16. Nuclear fuel element nut retainer cup

    International Nuclear Information System (INIS)

    Walton, L.A.


    A typical embodiment has an end fitting for a nuclear reactor fuel element that is joined to the control rod guide tubes by means of a nut plate assembly. The nut plate assembly has an array of nuts, each engaging the respective threaded end of the control rod guide tubes. The nuts, moreover, are retained on the plate during handling and before fuel element assembly by means of hollow cylindrical locking cups that are brazed to the plate and loosely circumscribe the individual enclosed nuts. After the nuts are threaded onto the respective guide tube ends, the locking cups are partially deformed to prevent one or more of the nuts from working loose during reactor operation. The locking cups also prevent loose or broken end fitting parts from becoming entrained in the reactor coolant

  17. Suicidal ideation and attempts in patients with stroke: a population-based study. (United States)

    Chung, Jae Ho; Kim, Jung Bin; Kim, Ji Hyun


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

  18. Does caregiver well-being predict stroke survivor depressive symptoms? A mediation analysis. (United States)

    Grant, Joan S; Clay, Olivio J; Keltner, Norman L; Haley, William E; Wadley, Virginia G; Perkins, Martinique M; Roth, David L


    Studies suggest that family caregiver well-being (ie, depressive symptoms and life satisfaction) may affect stroke survivor depressive symptoms. We used mediation analysis to assess whether caregiver well-being might be a factor explaining stroke survivor depressive symptoms, after controlling for demographic factors and stroke survivor impairments and problems. Caregiver/stroke participant dyads (N = 146) completed measures of stroke survivor impairments and problems and depressive symptoms and caregiver depressive symptoms and life satisfaction. Mediation analysis was used to examine whether caregiver well-being mediated the relationship between stroke survivor impairments and problems and stroke survivor depressive symptoms. As expected, more stroke survivor problems and impairments were associated with higher levels of stroke survivor depressive symptoms (P mediated by caregiver life satisfaction (29.29%) and caregiver depressive symptoms (32.95%). Although these measures combined to account for 40.50% of the relationship between survivor problems and impairments and depressive symptoms, the direct effect remained significant. Findings indicate that stroke survivor impairments and problems may affect family caregivers and stroke survivors and a high level of caregiver distress may result in poorer outcomes for stroke survivors. Results highlight the likely importance of intervening with both stroke survivors and family caregivers to optimize recovery after stroke.

  1. Translation and Validation of a Chinese Version of the Stroke Self-Efficacy Questionnaire in Community-Dwelling Stroke Survivors. (United States)

    Lo, Suzanne Hoi Shan; Chang, Anne Marie; Chau, Janita Pak Chun


    Self-efficacy is a significant factor influencing stroke survivors' participation in self-care and outcomes. The Stroke Self-Efficacy Questionnaire (SSEQ) is a stroke-specific measure of stroke survivors' self-efficacy in performing daily functional activities and self-management. However, there has been no Chinese version of the questionnaire. The current study aims to examine the reliability and validity of a translated Chinese version of SSEQ (SSEQ-C). The English version of SSEQ has been translated into Chinese. A descriptive study was conducted. A convenience sample of 135 Chinese stroke survivors (mean age 58.9, SD 9.75) was recruited from three community centers and a stroke support group. Eligible participants completed the SSEQ-C, and the Chinese versions of General Self-Efficacy Scale (GSES), Frenchay Activities Index (FAI), and Stroke-Specific Quality of Life Scale (SSQOL). Thirty of the participants completed the questionnaires at baseline and 4 weeks afterwards. SSEQ-C had a high internal consistency (Cronbach's α 0.92). Test-retest reliability was satisfactory with the intraclass correlation coefficient of the total scale 0.52. Positive correlations were found between the total scores of SSEQ-C, GSES, FAI, and SSQOL (Spearman's ρ: 0.48-0.68, p self-efficacy in managing post-stroke condition. More studies are warranted to confirm the two-factor model of the questionnaire.

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

    Limited data exist on the performance of the revised Framingham Stroke Risk Score (R-FSRS) and the R-FSRS in conjunction with nontraditional risk markers. We compared the R-FSRS, original FSRS, and the Pooled Cohort Equation for stroke prediction and assessed the improvement in discrimination by nontraditional risk markers. Six thousand seven hundred twelve of 6814 participants of the MESA (Multi-Ethnic Study of Atherosclerosis) were included. Cox proportional hazard, area under the curve, net reclassification improvement, and integrated discrimination increment analysis were used to assess and compare each stroke prediction risk score. Stroke was defined as fatal/nonfatal strokes (hemorrhagic or ischemic). After mean follow-up of 10.7 years, 231 of 6712 (3.4%) strokes were adjudicated (2.7% ischemic strokes). Mean stroke risks using the R-FSRS, original FSRS, and Pooled Cohort Equation were 4.7%, 5.9%, and 13.5%. The R-FSRS had the best calibration (Hosmer-Lemeshow goodness-of-fit, χ 2 =6.55; P =0.59). All risk scores were predictive of incident stroke. C statistics of R-FSRS (0.716) was similar to Pooled Cohort Equation (0.716), but significantly higher than the original FSRS (0.653; P =0.01 for comparison with R-FSRS). Adding nontraditional risk markers individually to the R-FSRS did not improve discrimination of the R-FSRS in the area under the curve analysis, but did improve category-less net reclassification improvement and integrated discrimination increment for incident stroke. The addition of coronary artery calcium to R-FSRS produced the highest category-less net reclassification improvement (0.36) and integrated discrimination increment (0.0027). Similar results were obtained when ischemic strokes were used as the outcome. The R-FSRS downgraded stroke risk but had better calibration and discriminative ability for incident stroke compared with the original FSRS. Nontraditional risk markers modestly improved the discriminative ability of the R-FSRS, with

    Objective To evaluate relative accuracy of a newly developed Stroke Assessment of Fall Risk (SAFR) for classifying fallers and non-fallers, compared with a health system fall risk screening tool, the Fall Harm Risk Screen. Design and setting Prospective quality improvement study conducted at an inpatient stroke rehabilitation unit at a large urban university hospital. Participants Patients admitted for inpatient stroke rehabilitation (N = 419) with imaging or clinical evidence of ischemic or hemorrhagic stroke, between 1 August 2009 and 31 July 2010. Interventions Not applicable. Main outcome measure(s) Sensitivity, specificity, and area under the curve for Receiver Operating Characteristic Curves of both scales’ classifications, based on fall risk score completed upon admission to inpatient stroke rehabilitation. Results A total of 68 (16%) participants fell at least once. The SAFR was significantly more accurate than the Fall Harm Risk Screen (p stroke rehabilitation patients. While the SAFR improves upon the accuracy of a general assessment tool, additional refinement may be warranted. PMID:24849795

Similar to the results of previous studies, the authors found that delayed intraocular foreign body (IOFB management can result in good visual outcome without an apparent increased risk of endophthalmitis or other deleterious side effects. However, the authors failed to explain the exact reason for the diminution of vision in patients left eye. It is unclear what the uncorrected visual acuity was and what kind of correction was used, more precisely type and amount of cylinder, given the presence of the corneal opacity. Since the size of the IOFB is approximately 4x4x1mm, significant irido-corneal angle changes resulting in intraocular pressure raise and optic nerve head damage can be expected. Traumatic glaucoma following open globe injury can occur in 2.7 to 19% of cases, with several risk factors associated with glaucoma development (advanced age, poor visual acuity at presentation,perforating rather than penetrating ocular injury,lens injury, presence of vitreous hemorrhage and presence of an IOFB. Earlier reportsof latetraumaticoptic neuropathy onset, even after several years, indicate that this possibility cannot be completely ruled out too. Therefore, repeated intraocular pressure measurements, gonioscopy, pupillary reaction assessment, together with through posterior segment examination including visual field and optical coherence tomography examinations can be useful in determining the possible optic nerve damage as one of the possible reasons for visual acuity reduction. The authors did not suggest any operative treatment at this time. However, it should bear in mind that the inert anterior chamber IOFB could be a risk factor for non-infectious endophthalmitis development even after many years. Also, long term retained anterior chamber foreign body leads to permanent endothelial cell loss and can even result in a corneal

    CONTEXT AND OBJECTIVE: Whether endogenous sex hormones are associated with ischemic stroke (IS) is unclear. We tested the hypothesis that extreme concentrations of endogenous sex hormones are associated with risk of IS in the general population. DESIGN, SETTING, AND PARTICIPANTS: Adult men (n...... = 4615) and women (n = 4724) with measurements of endogenous sex hormones during the 1981-1983 examination of the Copenhagen City Heart Study, Denmark, were followed for up to 29 years for incident IS, with no loss to follow-up. Mediation analyses assessed whether risk of IS was mediated through...

  11. Immune interventions in stroke (United States)

    Fu, Ying; Liu, Qiang; Anrather, Josef


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

  16. The High Prevalence of Anxiety Disorders After Stroke. (United States)

    Cumming, Toby B; Blomstrand, Christian; Skoog, Ingmar; Linden, Thomas


    Previous studies indicate that post-stroke anxiety is common and persistent. We aimed to determine whether point prevalence of anxiety after stroke is higher than in the population at large, and whether the profile of anxiety symptoms is different. This case-control study was conducted in Göteborg, Sweden, with stroke patients recruited from the Sahlgrenska University Hospital and a comparison group selected from local population health studies. We included 149 stroke survivors (assessed at 20 months post-stroke) and 745 participants from the general population matched for age and sex. A comprehensive psychiatric interview was conducted, with anxiety and depressive disorders diagnosed according to DSM-III-R criteria. Those in the stroke group were significantly more likely than those in the comparison group to have generalized anxiety disorder (GAD) (27% versus 8%), phobic disorder (24% versus 8%) and obsessive-compulsive disorder (9% versus 2%). Multivariate regression indicated that being in the stroke group, female sex, and having depression were all significant independent associates of having an anxiety disorder. In terms of symptom profile, stroke survivors with GAD were significantly more likely to report vegetative disturbance than those in the comparison group with GAD but less likely to have observable muscle tension or reduced sleep. Point prevalence of anxiety disorders is markedly higher after stroke than in the general population, and this cannot be attributed to higher rates of comorbid depression. Copyright © 2016.

  17. Improve employee engagement to retain your workforce. (United States)

    Tullar, Jessica M; Amick, Benjamin C; Brewer, Shelley; Diamond, Pamela M; Kelder, Steven H; Mikhail, Osama


    Turnover hurts patient care quality and is expensive to hospitals. Improved employee engagement could encourage employees to stay at their organization. The aim of the study was to test whether participants in an employee engagement program were less likely than nonparticipants to leave their job. Health care workers (primarily patient care technicians and assistants, n = 216) were recruited to participate in an engagement program that helps employees find meaning and connection in their work. Using human resources data, we created a longitudinal study to compare participating versus nonparticipating employees in the same job titles on retention time (i.e., termination risk). Participants were less likely to leave the hospital compared to nonparticipating employees (hazard ratio = 0.22, 95% CI [0.11, 0.84]). This finding remained significant after adjusting for covariates (hazard ratio = 0.37, 95% CI [0.17, 0.57]). Improving employee engagement resulted in employees staying longer at the hospital.

  18. Acute ischemic stroke update. (United States)

    Baldwin, Kathleen; Orr, Sean; Briand, Mary; Piazza, Carolyn; Veydt, Annita; McCoy, Stacey


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

    Little information is available about the course of quality of life (QoL) post stroke and how dependency on activities of daily living (ADL) influences this course. The aim of this study was therefore to describe the course of QoL from 2 months up to 2 years post stroke and to study the influence of ADL dependency in the first week post stroke. This is a multicenter prospective longitudinal cohort study in which 368 stroke patients were included and data were collected at 1 week, 2 months, 6 months, 12 months and 24 months post stroke. QoL assessment included measures of health-related quality of life (HRQoL) (short stroke-specific Quality of Life Scale), emotional functioning (Hospital Anxiety and Depression Scale), participation (Utrecht Scale for Evaluation of Rehabilitation-Participation), and life satisfaction (2LS). Dependency on ADL was defined as having a Barthel Index score ≤ 17 four days post stroke. Generalized Estimating Equations analyses were performed to examine the course of the 4 domains of QoL. Furthermore, the possible confounding effect of age, gender, marital status, level of education and discharge destination was examined. Results showed that HRQoL, participation and life satisfaction improved during the first year post stroke, with most changes occurring in the first 6 months. Furthermore, patients dependent in ADL scored consistently lower on all 4 QoL domains and test occasions compared to ADL-independent patients. In both patient groups separately, no changes over time were found in emotional functioning. ADL-independent patients improved in HRQoL (p = 0.002), participation (p post stroke and showed different patterns for specific domains of QoL and for patients with and without dependency in ADL in the first week post stroke. It is therefore important to differentiate between these different domains of QoL when the long-term perspective is considered. Furthermore, patients dependent in ADL consistently scored lower on all QoL domains

  1. Carotid IMT is more associated with stroke than risk calculators. (United States)

    Owolabi, M O; Akpa, O M; Agunloye, A M


    It is unclear whether a natural marker of atherosclerosis (carotid intima-media thickness: CIMT) or calculated risk score is more associated with stroke. We therefore comparatively examined the relationship between CIMT as well as two cardiovascular risk calculators (Omnibus Risk Score -ORS and Framingham Risk Score- FRS) and the occurrence of stroke among hypertensive African patients. CIMT was measured in 555 consecutive consenting hypertensive adults (377 stroke patients and 178 stroke-free subjects). The 10-year cardiovascular risk was calculated for each participant with the FRS and ORS. The strengths of association between FRS, ORS, CIMT, and stroke occurrence were examined using logistic regression. The discriminative capacity of FRS, ORS, and CIMT for stroke occurrence was assessed with c-statistics. Higher average CIMT (OR 11.71; 95% CI 1.65-83.07; P = 0.01) was strongly associated with stroke after adjusting for age, sex, blood pressure, serum cholesterol, and blood sugar. Neither the FRS (OR: 1.03; CI: 0.89-1.19, P = 0.68) nor the ORS (OR: 1.08; CI: 0.90-1.30; P = 0.41) was significantly associated with stroke. CIMT had a higher c-statistic for differentiating stroke patients from hypertensive controls (right: c = 0.63, P < 0.001; left: c = 0.67, P < 0.001; average: c = 0.66, P < 0.001) than some conventional risk factors. Neither FRS (P = 0.39) nor ORS (P = 0.55) was able to independently differentiate between stroke and hypertensive patients. CIMT, but neither FRS nor ORS, is independently associated with stroke among Nigerian African hypertensive patients. CIMT may be a better tool for estimating the overall risk of stroke than FRS or ORS in this population. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    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.

  3. Stroke mimic diagnoses presenting to a hyperacute stroke unit. (United States)

    Dawson, Ang; Cloud, Geoffrey C; Pereira, Anthony C; Moynihan, Barry J


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

  5. Cerebrorenal interaction and stroke. (United States)

    Toyoda, Kazunori


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

  8. The Importance of Patient Involvement in Stroke Rehabilitation (United States)


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

  9. Acute Predictors of Social Integration Following Mild Stroke. (United States)

    Wise, Frances M; Harris, Darren W; Olver, John H; Davis, Stephen M; Disler, Peter B


    Despite an acknowledged need to accurately predict stroke outcome, there is little empirical evidence regarding acute predictors of participation restriction post stroke. The current study examines prediction of social integration following mild stroke, using combinations of acute poststroke factors. In a prospective, longitudinal study, a cohort of 60 stroke survivors was followed up at 6 months post stroke. Hierarchical multiple regression analyses were employed to evaluate the value of acute poststroke variables in predicting social integration at 6 months post stroke. A combination of age, number of comorbidities, stroke severity, social support factors, and general self-efficacy in the acute poststroke period accounted for 42% of the variance in 6-month social integration. The largest amount of variance (20%) was explained by inclusion of social support factors, including number and types of support. Post hoc analysis was conducted to establish whether marital status was the mediating variable through which early poststroke social support factors exerted influence upon subsequent social integration. The new combination of acute variables accounted for 48% of the variance in 6-month social integration. Results suggested that subjects with partners perceived higher levels of functional social support and lower levels of participation restriction. Stroke survivors with partners may receive greater amounts of companionship and encouragement from their partners, which enhances self-esteem and confidence. Such individuals are possibly more able to participate in and maintain relationships, thus improving social integration. Social support factors, mediated via marital status, are the strongest predictors of subsequent social integration following mild stroke. Copyright © 2018 National Stroke Association.

  10. Perception of Recurrent Stroke Risk among Black, White and Hispanic Ischemic Stroke and Transient Ischemic Attack Survivors: The SWIFT Study (United States)

    Boden-Albala, Bernadette; Carman, Heather; Moran, Megan; Doyle, Margaret; Paik, Myunghee C.


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

  12. Dietary patterns are associated with incident stroke and contribute to excess risk of stroke in Black Americans (United States)

    Judd, Suzanne E; Gutiérrez, Orlando M.; Newby, PK; Howard, George; Howard, Virginia J; Locher, Julie L; Kissela, Brett M; Shikany, James M


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

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

    LENUS (Irish Health Repository)

    Hickey, Anne


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

  14. Screw retained vs. cement retained implant-supported fixed dental prosthesis. (United States)

    Wittneben, Julia-Gabriela; Joda, Tim; Weber, Hans-Peter; Brägger, Urs


    A fixed dental prosthesis can be secured to an endosseous implant via cementation (using a provisional or definitive cement) on an implant abutment that is screw retained to the implant or directly in the implant via screw retention. The clinical decision as to which retention system best suits the individual patient depends on several factors. The aim of this review is to present a detailed overview of the factors potentially influencing whether to choose screw retention or cement retention. These factors include the individual indication, advantages and disadvantages of the different retention mechanisms, the retention provided, retrievability, provisionalization, esthetics and clinical performance, including failures and complications. The results of recently published systematic reviews on this topic are discussed and an overview is provided. A decision tree is presented to facilitate the clinical selection of the retention type. This overview concludes that the choice of retention type (screw retained or cement retained) might not influence the overall survival of the implant-supported fixed dental prosthesis, but may be responsible for the development of certain complications. The decision may depend on technical feasibility and on weighing the pros and cons. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    The literature about the relationship between obstructive sleep apnea (OSA) and stroke location is conflicting with some studies finding an association and others demonstrating no relationship. Among acute ischemic stroke patients, we sought to examine the relationship between stroke location and the prevalence of OSA; OSA severity based on apnea-hypopnea index (AHI), arousal frequency, and measure of hypoxia; and number of central and obstructive respiratory events. Data were obtained from patients who participated in a randomized controlled trial (NCT01446913) that evaluated the effectiveness of a strategy of diagnosing and treating OSA among patients with acute ischemic stroke and transient ischemic attack. Stroke location was classified by brain imaging reports into subdivisions of lobes, subcortical areas, brainstem, cerebellum, and vascular territory. The association between acute stroke location and polysomnographic findings was evaluated using logistic regression for OSA presence and negative binomial regression for AHI. Among 73 patients with complete polysomnography and stroke location data, 58 (79%) had OSA. In unadjusted models, no stroke location variable was associated with the prevalence or severity of OSA. Similarly, in multivariable modeling, groupings of stroke location were also not associated with OSA presence. These results indicate that OSA is present in the majority of stroke patients and imply that stroke location cannot be used to identify a group with higher risk of OSA. The results also suggest that OSA likely predated the stroke. Given this high overall prevalence, strong consideration should be given to obtaining polysomnography for all ischemic stroke patients.

  16. STEM Education: Attracting and Retaining Female Students in Secondary STEM programs (United States)

    Ruff, Zachary A.

    This narrative case study examines a high achieving STEM based high school and its ability to attract, retains, and engage female students. Given the recent importance placed on STEM graduates and STEM careers it is important for schools to understand how they can engage traditionally underserved minorities in STEM fields. The research used a series of semi-structured interviews in an attempt to understand the point of view of the female student participants to try to comprehend the factors that allowed one school to not only attract female students to its program, but also to retain them and keep them engaged throughout their education.

    Cassoudesalle, H; Nozères, A; Petit, H; Cressot, V; Muller, F; Rouanet, F; Sibon, I; Joseph, P-A; Dehail, P


    The main objective of this study was to describe the distribution of referrals offered to patients assessed in the "Post-Acute Stroke program" of Bordeaux University Hospital (France). This program was developed in 2008 to organize the dispensation of care in rehabilitation units specialized in neurological diseases. This was a single-centre observational study. Between July 2008 and December 2012, data on the number of stroke patients hospitalized at the Bordeaux University Hospital and their post-acute referral were collected from the local hospital discharge database. Some of these patients were assessed by Physical Rehabilitation and Medicine physicians participating in the program. Proposed and actual referrals, time from admission to assessment and functional status were also collected. Among 4189 stroke patients, 1465 (35%) survivors were assessed, of whom 932 (22.2%) were discharged to inpatient rehabilitation facilities. There were no patients discharged to this type of unit without an assessment. Among the 1465 patients who were assessed, 57.2% were referred to specialized rehabilitation units, 6.3% were discharged to non-specialized rehabilitation units and 26% returned home directly. The median total length of stay in acute units varied from 10 to 15days depending on referral orientation. Patients that were assessed were more likely to be transferred to specialized rehabilitation units than to non-specialized rehabilitation units. The Post-Acute Stroke program has the particularity of combining private and public specialized rehabilitation units in a common collaborative referral system while retaining the control and flexibility of personalised referral for each patient in the light of local care availability.

  20. Developing the Stroke Exercise Preference Inventory (SEPI.

    Directory of Open Access Journals (Sweden)

    Nicholas S Bonner

    Full Text Available Physical inactivity is highly prevalent after stroke, increasing the risk of poor health outcomes including recurrent stroke. Tailoring of exercise programs to individual preferences can improve adherence, but no tools exist for this purpose in stroke.We identified potential questionnaire items for establishing exercise preferences via: (i our preliminary Exercise Preference Questionnaire in stroke, (ii similar tools used in other conditions, and (iii expert panel consultations. The resulting 35-item questionnaire (SEPI-35 was administered to stroke survivors, along with measures of disability, depression, anxiety, fatigue and self-reported physical activity. Exploratory factor analysis was used to identify a factor structure in exercise preferences, providing a framework for item reduction. Associations between exercise preferences and personal characteristics were analysed using multivariable regression.A group of 134 community-dwelling stroke survivors (mean age 64.0, SD 13.3 participated. Analysis of the SEPI-35 identified 7 exercise preference factors (Supervision-support, Confidence-challenge, Health-wellbeing, Exercise context, Home-alone, Similar others, Music-TV. Item reduction processes yielded a 13-item version (SEPI-13; in analysis of this version, the original factor structure was maintained. Lower scores on Confidence-challenge were significantly associated with disability (p = 0.002, depression (p = 0.001 and fatigue (p = 0.001. Self-reported barriers to exercise were particularly prevalent in those experiencing fatigue and anxiety.The SEPI-13 is a brief instrument that allows assessment of exercise preferences and barriers in the stroke population. This new tool can be employed by health professionals to inform the development of individually tailored exercise interventions.

  1. Redistribution of retained particles. Effect of hyperpnea

    International Nuclear Information System (INIS)

    Valberg, P.A.; Wolff, R.K.; Mauderly, J.L.


    The effect of postexposure hyperpnea on clearance of particles deposited in the lungs of adult male beagle dogs was examined. Sedated dogs inhaled an insoluble 67 Gg 2 O 3 (T 1/2 . 78 h) aerosol (0.12 micron AMD) for one half hour on three separate occasions. Following aerosol exposures 1 and 2, dogs were assigned to either an eupneic (EUP) or hyperpneic (HYP) group and clearance was followed noninvasively for 9 days by whole body counting and gamma camera analysis. After exposure 2, EUP and HYP assignments were interchanged so that each dog was studied under both conditions. Hyperpnea was induced by housing dogs in an atmosphere of 7% CO 2 in air, 6 h per day. Carbon dioxide inhalation increased VE a factor of 3.7 +/- 0.9 (SD). The authors found that pulmonary clearance was retarded by CO 2 -stimulated hyperpnea in 7 of 8 dogs. Following aerosol exposure 3, dogs were divided between EUP and HYP and subsequently were killed in pairs at 3 h, 1 day, 3 days, and 7 days. Distribution of activity in body organs was examined, and translocation to the hilar lymph nodes was followed. Both retention distribution and removal of activity by saline lavage were measured in postmortem lungs. The percentage of lavaged activity associated with pulmonary macrophages increased from 44% at 3 h after exposure to 91% at 4 and 7 days after exposure. Examination of dried lung slices by autoradiography showed clearance of particles from airways and formation of a more punctate distribution in the retained activity at increasing times after exposure. Distinctive differences between HYP and EUP dogs were not seen

  2. Attracting and retaining doctors in rural Nepal. (United States)

    Shankar, P R


    In Nepal, a number of private sector medical schools have opened recently; although sufficient numbers of doctors are graduating there continues to be a doctor shortage in rural areas. This article analysed the rural doctor shortage in Nepal and reviewed the international literature for strategies that may be suitable for use in Nepal. Original research articles, reviews, magazine articles and project reports dealing with Nepal and other developing countries during the period 1995 to 2010 were sourced via Google, Google Scholar and Pubmed. Full text access was obtained via WHO's HINARI database. The health workforce in Nepal is unevenly distributed resulting in doctor shortages in rural areas. The recent introduction of mandatory rural service for scholarship students was aimed to reduce the loss of medical graduates to developed nations. High tuition fees in private medical schools and low Government wages prevent recent graduates from taking up rural positions, and those who do face many challenges. Potential corrective strategies include community-based medical education, selecting rural-background medical students, and providing a partial or complete tuition fee waiver for medical students who commit to rural service. Traditional healers and paramedical staff can also be trained for and authorized to provide rural health care. A range of strategies developed elsewhere could be used in Nepal, especially community-oriented medical education that involves rural doctors in training medical students. The reimbursement of tuition fees, assistance with relocation, and provision of opportunities for academic and professional advancement for rural doctors should also be considered. Government investment in improving working conditions in rural Nepal would assist rural communities to attract and retain doctors.

  3. Dizziness in stroke

    Directory of Open Access Journals (Sweden)

    M. V. Zamergrad


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

  4. Relationship between visuospatial neglect and kinesthetic deficits after stroke. (United States)

    Semrau, Jennifer A; Wang, Jeffery C; Herter, Troy M; Scott, Stephen H; Dukelow, Sean P


    After stroke, visuospatial and kinesthetic (sense of limb motion) deficits are common, occurring in approximately 30% and 60% of individuals, respectively. Although both types of deficits affect aspects of spatial processing necessary for daily function, few studies have investigated the relationship between these 2 deficits after stroke. We aimed to characterize the relationship between visuospatial and kinesthetic deficits after stroke using the Behavioral Inattention Test (BIT) and a robotic measure of kinesthetic function. Visuospatial attention (using the BIT) and kinesthesia (using robotics) were measured in 158 individuals an average of 18 days after stroke. In the kinesthetic matching task, the robot moved the participant's stroke-affected arm at a preset direction, speed, and magnitude. Participants mirror-matched the robotic movement with the less/unaffected arm as soon as they felt movement in their stroke affected arm. We found that participants with visuospatial inattention (neglect) had impaired kinesthesia 100% of the time, whereas only 59% of participants without neglect were impaired. For those without neglect, we observed that a higher percentage of participants with lower but passing BIT scores displayed impaired kinesthetic behavior (78%) compared with those participants who scored perfect or nearly perfect on the BIT (49%). The presence of visuospatial neglect after stroke is highly predictive of the presence of kinesthetic deficits. However, the presence of kinesthetic deficits does not necessarily always indicate the presence of visuospatial neglect. Our findings highlight the importance of assessment and treatment of kinesthetic deficits after stroke, especially in patients with visuospatial neglect. © The Author(s) 2014.

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

  7. Clinical neurogenetics: stroke. (United States)

    Rost, Natalia S


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

    Migraine and stroke are common neurovascular disorders which share underlying physiological processes. Increased risks of ischemic stroke, hemorrhagic stroke, and subclinical ischemic lesions have been consistently found in migraineurs. Three possible associations are suggested. One is that underlying pathophysiology of migraine can lead to ischemic stroke. Second, common comorbidities between migraine and stroke can be present. Lastly, some syndromes can manifest with both migraine-like head...

  15. Intrinsic factors influencing help-seeking behaviour in an acute stroke situation. (United States)

    Zock, Elles; Kerkhoff, Henk; Kleyweg, Ruud Peter; van de Beek, Diederik


    The proportion of stroke patients eligible for intravenous or intra-arterial treatment is still limited because many patients do not seek medical help immediately after stroke onset. The aim of our study was to explore which intrinsic factors and considerations influence help-seeking behaviour of relatively healthy participants, confronted with stroke situations. Semi-structured interviews were conducted with 25 non-stroke participants aged 50 years or older. We presented 5 clinical stroke situations as if experienced by the participants themselves. Recognition and interpretation of symptoms were evaluated and various factors influencing help-seeking behaviour were explored in-depth. We used the thematic synthesis method for data analysis. Five themes influencing help-seeking behaviour in a stroke situation were identified: influence of knowledge, views about seriousness, ideas about illness and health, attitudes towards others and beliefs about the emergency medical system. A correct recognition of stroke symptoms or a correct interpretation of the stroke situations did not automatically result in seeking medical help. Interestingly, similar factors could lead to different types of actions between participants. Many intrinsic, as well as social and environmental factors are of influence on help-seeking behaviour in an acute stroke situation. All these factors seem to play a complex role in help-seeking behaviour with considerable inter-individual variations. Accomplishing more patients eligible for acute stroke treatment, future research should focus on better understanding of all factors at various levels grounded in a theory of help-seeking behaviour.

    Full Text Available The effects of stroke on stroke survivors are profound and affecttheir quality of life. The aim of this study was to establish the experience of peopleliving with stroke in low socioeconomic urban and rural areas of South Africa.A qualitative study using semi-structured interviews was used to collect data.Participants were identified from stroke registers and recruited from PHC clinicsin Soweto, Gauteng and Limpopo provinces. Participants had to have had a stroke,be above the age of 18 and had lived in the community six months to a year followingtheir stroke. The researcher or research assistant conducted the interviews ofparticipants who had had strokes as well as their caregivers in the home language of the participants. The interviewswere audio taped, transcribed and translated into English. A thematic content analysis was done.Thirty two participants were interviewed, 13 from Soweto, Gauteng, and 19 from rural Limpopo provinces. Theresults suggest that the sudden, overwhelming transformation as a result of a stroke forms a background for loss ofcommunity mobility, social isolation, role reversal within the family and community, loss of role within the family andcommunity, loss of meaningful activities of daily living, loss of hope and threat to livelihood amongst stroke survivorsliving in low socioeconomic areas of South Africa.An overwhelming picture of despondency was found, with few positive stories told in both settings. The themesidentified from the interviews reflected the experience and issues that a patient with stroke has to deal with in lowsocioeconomic areas of South Africa.

    To evaluate relative accuracy of a newly developed Stroke Assessment of Fall Risk (SAFR) for classifying fallers and non-fallers, compared with a health system fall risk screening tool, the Fall Harm Risk Screen. Prospective quality improvement study conducted at an inpatient stroke rehabilitation unit at a large urban university hospital. Patients admitted for inpatient stroke rehabilitation (N = 419) with imaging or clinical evidence of ischemic or hemorrhagic stroke, between 1 August 2009 and 31 July 2010. Not applicable. Sensitivity, specificity, and area under the curve for Receiver Operating Characteristic Curves of both scales' classifications, based on fall risk score completed upon admission to inpatient stroke rehabilitation. A total of 68 (16%) participants fell at least once. The SAFR was significantly more accurate than the Fall Harm Risk Screen (p Fall Harm Risk Screen, area under the curve was 0.56, positive predictive value was 0.19, and negative predictive value was 0.86. Sensitivity and specificity of the SAFR (0.78 and 0.63, respectively) was higher than the Fall Harm Risk Screen (0.57 and 0.48, respectively). An evidence-derived, population-specific fall risk assessment may more accurately predict fallers than a general fall risk screen for stroke rehabilitation patients. While the SAFR improves upon the accuracy of a general assessment tool, additional refinement may be warranted. © The Author(s) 2014.

    Kanaga Lakshmi


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

    To gain better understanding of (i) beliefs and knowledge about stroke; (ii) attitudes about walking for stroke prevention; and (iii) barriers and facilitators to walking among Korean seniors for the cultural tailoring of a stroke prevention walking programme. Physical inactivity is a major risk factor for stroke. Korean immigrant seniors are one of the most sedentary ethnic groups in the United States. An explorative study using focus group data. Twenty-nine Korean immigrant seniors (64-90 years of age) who had been told by a doctor at least once that their blood pressure was elevated participated in 3 focus groups. Each focus group consisted of 8-11 participants. Focus group audiotapes were transcribed and analysed using standard content analysis methods. Participants identified physical and psychological imbalances (e.g. too much work and stress) as the primary causes of stroke. Restoring 'balance' was identified as a powerful means of stroke prevention. A subset of participants expressed that prevention may be beyond human control. Overall, participants acknowledged the importance of walking for stroke prevention, but described barriers such as lack of personal motivation and unsafe environment. Many participants believed that providing opportunities for socialisation while walking and combining walking with health information sessions would facilitate participation in and maintenance of a walking programme. Korean immigrant seniors believe strongly that imbalance is a primary cause of stroke. Restoring balance as a way to prevent stroke is culturally special among Koreans and provides a conceptual base in culturally tailoring our stroke prevention walking intervention for Korean immigrant seniors. A stroke prevention walking programme for Korean immigrant seniors may have greater impact by addressing beliefs about stroke causes and prevention such as physical and psychological imbalances and the importance of maintaining emotional well-being. © 2016 John

  3. Does Stroke Contribute to Racial Differences in Cognitive Decline? (United States)

    Levine, Deborah A.; Kabeto, Mohammed; Langa, Kenneth M.; Lisabeth, Lynda D.; Rogers, Mary A.M.; Galecki, Andrzej T.


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

  5. Neighborhood cohesion is associated with reduced risk of stroke mortality. (United States)

    Clark, Cari Jo; Guo, Hongfei; Lunos, Scott; Aggarwal, Neelum T; Beck, Todd; Evans, Denis A; Mendes de Leon, Carlos; Everson-Rose, Susan A


    Greater social cohesion is related to lower rates of coronary heart disease, but its relation to stroke risk is unstudied. This study examined whether neighborhood social cohesion was protective against stroke mortality and incidence. Data come from 5789 participants (60% female; 62% black; mean age, 74.7 years) in a longitudinal study of chronic diseases in the elderly. Stroke mortality, ascertained through December 31, 2007, was verified through the National Death Index; 186 stroke deaths were identified in 11 years of follow-up. Stroke incidence was determined in a subset (N=3816) with linkage to Medicare claims files; 701 first-ever strokes were identified. Cohesion was measured by 6 items assessing frequency of contact and social interactions with neighbors; items were z-scored and averaged. Individual scores were averaged across 82 census block groups, forming a neighborhood-level measure of social cohesion. Marginal Cox proportional hazard models tested the association of neighborhood-level cohesion with stroke mortality and incidence. Each 1-point increase in cohesion related to a 53% reduced risk of stroke mortality (hazard ratio, 0.47; 95% CI, 0.24 to 0.90), adjusting for relevant covariates, including sociodemographics, known stroke risk factors, and neighborhood-level socioeconomic status. A race×cohesion interaction (P=0.04) revealed cohesion was protective in whites (hazard ratio, 0.34; 95% CI, 0.17 to 0.67) but not blacks (hazard ratio, 1.17; 95% CI, 0.35 to 3.86). Cohesion was unrelated to stroke incidence (P>0.5). Neighborhood-level social cohesion was independently protective against stroke mortality. Research is needed to further examine observed race differences and pathways by which cohesion is health-protective.

  6. Clinical experience with direct-bonded orthodontic retainers. (United States)

    Zachrisson, B U


    The experience obtained in clinical evaluation of forty-three direct-bonded mandibular canine-to-canine retainers after a minimum observation period of 1 year (range, 1 to 2.5 years) is summarized. Results indicate that the bonded retainer has all the advantages of a fixed soldered retainer, in addition to being invisible. Patient acceptance was excellent, and the failure rate in terms of loose retainers was low. Also, for a number of other retention problems, direct bonding with different types of lingual wire seems to open up a range of promising new possibilities.

  12. Developing a falls prevention program for community-dwelling stroke survivors in Singapore: client and caregiver perspectives. (United States)

    Xu, Tianma; O'Loughlin, Kate; Clemson, Lindy; Lannin, Natasha A; Dean, Catherine; Koh, Gerald


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

  13. Plasma Magnesium and the Risk of Ischemic Stroke among Women (United States)

    Akarolo-Anthony, Sally N.; Jiménez, Monik C.; Chiuve, Stephanie E.; Spiegelman, Donna; Willett, Walter C.; Rexrode, Kathryn M.


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

    Stroke rehabilitation is a complex intervention. Many factors influence the interaction between the patient and the elements of the intervention. Rehabilitation interventions are aimed at altering different domains of patient outcome including body functions, activity and participation. As a consequence, randomised clinical trials in this area are difficult to design. We developed an archive of stroke rehabilitation trials (VISTA-Rehab) to act as a resource to help trialists model and design future rehabilitation studies. We developed specific eligibility criteria for the entry of stroke rehabilitation trials into the archive. We established a Steering Committee to oversee projects and publications and commenced the recruitment of rehabilitation trials into this resource. As of August 2009, VISTA-Rehab contains data from 23 stroke rehabilitation trials (>3400 patients). Demographic data, including age [median=73, interquartile range (63,79)], gender (male=53%) and initial dependency [median baseline Barthel index score=6, interquartile range (9,19)], are available for all patients. Outcome measures include the modified Rankin Scale, Barthel Index, Rivermead Motor Assessment, Fugl-Meyer Assessment, General Health Questionnaire and Nottingham Extended Activities of Daily Living Scale. VISTA-Rehab expands the Virtual International Stroke Trials Archive to include rehabilitation trials. Anonymised data can be used to examine questions specific to stroke rehabilitation and to generate novel hypotheses. © 2010 The Authors.

  15. Implementation of a Stroke Competency Program to Improve Nurses' Knowledge of and Adherence to Stroke Guidelines. (United States)

    Reynolds, Staci Sue; Murray, Laura L; McLennon, Susan M; Bakas, Tamilyn


    Nurses play an integral part in providing evidence-based care to patients with stroke, yet some patients receive unnecessary or even harmful care. The literature supports the use of multifaceted strategies to promote implementation of evidence-based practice; however, there is a gap in knowing which combinations of strategies are most successful. The purpose of this study was to determine if a tailored, multifaceted Stroke Competency Program would improve nurses' knowledge of and adherence to evidence-based practices in the care of patients with stroke. This program bundled implementation strategies of local opinion leaders, printed educational materials, and educational outreach. This study used a pretest/posttest program design. Nursing adherence was measured via documentation audits with knowledge measured by an author-developed assessment. Most participating nurses had approximately 10 years of nursing experience and were baccalaureate prepared; participation ranged from 32% to 58% (n = 88). Overall, an improvement in nursing adherence was noted after the program as well as significant improvements in nursing knowledge. Although the Stroke Competency Program improved nursing knowledge of and adherence to stroke guidelines, future research should seek to extend these findings to identify which bundle of strategies are most effective for implementing evidence into nursing practice using psychometrically sound outcome measures.

  17. Telestroke in stroke survivors. (United States)

    Joubert, Jacques; Joubert, Lynette B; de Bustos, Elizabeth Medeiros; Ware, Dallas; Jackson, David; Harrison, Terrence; Cadilhac, Dominique


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

  18. Autopsy approach to stroke. (United States)

    Love, Seth


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

  19. Post-stroke dyskinesias

    Directory of Open Access Journals (Sweden)

    Nakawah MO


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

  20. No difference in stroke knowledge between Korean adherents to traditional and western medicine – the AGE study: an epidemiological study

    Directory of Open Access Journals (Sweden)

    Eun Su-Yong


    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

  1. Virtual reality for stroke rehabilitation. (United States)

    Laver, Kate E; Lange, Belinda; George, Stacey; Deutsch, Judith E; Saposnik, Gustavo; Crotty, Maria


    Virtual reality and interactive video gaming have emerged as recent treatment approaches in stroke rehabilitation with commercial gaming consoles in particular, being rapidly adopted in clinical settings. This is an update of a Cochrane Review published first in 2011 and then again in 2015. Primary objective: to determine the efficacy of virtual reality compared with an alternative intervention or no intervention on upper limb function and activity.Secondary objectives: to determine the efficacy of virtual reality compared with an alternative intervention or no intervention on: gait and balance, global motor function, cognitive function, activity limitation, participation restriction, quality of life, and adverse events. We searched the Cochrane Stroke Group Trials Register (April 2017), CENTRAL, MEDLINE, Embase, and seven additional databases. We also searched trials registries and reference lists. Randomised and quasi-randomised trials of virtual reality ("an advanced form of human-computer interface that allows the user to 'interact' with and become 'immersed' in a computer-generated environment in a naturalistic fashion") in adults after stroke. The primary outcome of interest was upper limb function and activity. Secondary outcomes included gait and balance and global motor function. Two review authors independently selected trials based on pre-defined inclusion criteria, extracted data, and assessed risk of bias. A third review author moderated disagreements when required. The review authors contacted investigators to obtain missing information. We included 72 trials that involved 2470 participants. This review includes 35 new studies in addition to the studies included in the previous version of this review. Study sample sizes were generally small and interventions varied in terms of both the goals of treatment and the virtual reality devices used. The risk of bias present in many studies was unclear due to poor reporting. Thus, while there are a large

  2. Communication in conversation in stroke patients. (United States)

    Rousseaux, Marc; Daveluy, Walter; Kozlowski, Odile


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

  3. Prevalence of physical activity and sedentary behavior among stroke survivors in the United States. (United States)

    Butler, Eboneé N; Evenson, Kelly R


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

  4. Improving public education about stroke. (United States)

    Alberts, Mark J


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

  5. Primary prevention of stroke by a healthy lifestyle in a high-risk group. (United States)

    Larsson, Susanna C; Åkesson, Agneta; Wolk, Alicja


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

    Full Text Available ABSTRACT Aiming to contribute to studies that use detailed clinical and genomic information of biobanks, we present the initial results of the first Latin American Stroke Biobank. Methods: Blood samples were collected from patients included in the Joinville Stroke Registry and four Brazilian cities. Demographic socio-economic data, cardiovascular risk factors, Causative Classification System for Ischemic Stroke, Trial of Org 10172 in Acute Stroke Treatment and National Institutes of Health scores, functional stroke status (modified Rankin and brain images were recorded. Additionally, controls from both geographic regions were recruited. High-molecular-weight genomic DNA was obtained from all participants. Results: A total of 2,688 patients and 3,282 controls were included. Among the patients, 76% had ischemic stroke, 12% transient ischemic attacks, 9% hemorrhagic stroke and 3% subarachnoid hemorrhage. Patients with undetermined ischemic stroke were most common according the Trial of Org 10172 in Acute Stroke Treatment (40% and Causative Classification System for Ischemic Stroke (47% criteria. A quarter of the patients were under 55 years of age at the first-ever episode. Conclusions: We established the Joinville Stroke Biobank and discuss its potential for contributing to the understanding of the risk factors leading to stroke.

    Asghar Dalvandi


    Full Text Available Objectives: Stroke survivors develop their own strategies to combat disabilities, developing strategies to maintain or reestablish a sense of continuity after the disruptive life event that stroke represents, using strategies to foster hope during the process of adjusting to life after stroke and drawing on spiritual practices. The aim of this study is to identify the used and recommended strategies of life after stroke among Iranian people. Methods: A grounded theory approach was recruited using semi-structured interviews with 10 stroke survivors, 12 family caregivers and 6 formal care givers. Results: Five main concepts emerged describing as the used and recommended strategies of the participants including, improving functional performance, re-learning life skills and educational support, accessing to rehabilitative services, socio-economical support and well-suited coping strategies. Discussion: Participants valued better knowledge and skills regarding the adaptive strategies for stroke survivors and their family care givers are essential in accomplishing with activities of daily living and doing social roles for improving life after stroke. Also developing the socio- economic supports is crucial for assuring a more supportive approach to achieve rehabilitation services and design better educational program for them.

  8. Understanding nursing practice in stroke units: a Q-methodological study. (United States)

    Clarke, David J; Holt, Janet


    Nurses represent the largest professional group working with stroke-survivors, but there is limited evidence regarding nurses' involvement in post-stroke rehabilitation. The purpose of this study was to identify and explore the perspectives of nurses and other multidisciplinary stroke team members on nurses' practice in stroke rehabilitation. Q-methodological study with 63 multidisciplinary stroke unit team members and semi-structured interviews with 27 stroke unit team members. Irrespective of their professional backgrounds, participants shared the view that nurses can make an active contribution to stroke rehabilitation and integrate rehabilitation principles in routine practice. Training in stroke rehabilitation skills was viewed as fundamental to effective stroke care, but nurses do not routinely receive such training. The view that integrating rehabilitation techniques can only occur when nursing staffing levels were high was rejected. There was also little support for the view that nurses are uniquely placed to co-ordinate care, or that nurses have an independent rehabilitation role. The contribution that nurses with stroke rehabilitation skills can make to effective stroke care was understood. However, realising the potential of nurses as full partners in stroke rehabilitation is unlikely to occur without introduction of structured competency-based multidisciplinary training in rehabilitation skills. Implications for Rehabilitation Multidisciplinary rehabilitation in stroke units is a cornerstone of effective stroke care. Views of stroke unit team members on nurses' involvement in rehabilitation have not been reported previously. Nurses can routinely incorporate rehabilitation principles in their care. Specialist competency-based stroke rehabilitation training needs to be provided for nurses as well as for allied health professionals.

  9. Dietary fibre intake and risk of ischaemic and haemorrhagic stroke in the UK Women's Cohort Study. (United States)

    Threapleton, D E; Burley, V J; Greenwood, D C; Cade, J E


    Stroke risk is modifiable through many risk factors, one being healthy dietary habits. Fibre intake was associated with a reduced stroke risk in recent meta-analyses; however, data were contributed by relatively few studies, and few examined different stroke types. A total of 27,373 disease-free women were followed up for 14.4 years. Diet was assessed with a 217-item food frequency questionnaire and stroke cases were identified using English Hospital Episode Statistics and mortality records. Survival analysis was applied to assess the risk of total, ischaemic or haemorrhagic stroke in relation to fibre intake. A total of 135 haemorrhagic and 184 ischaemic stroke cases were identified in addition to 138 cases where the stroke type was unknown or not recorded. Greater intake of total fibre, higher fibre density and greater soluble fibre, insoluble fibre and fibre from cereals were associated with a significantly lower risk for total stroke. For total stroke, the hazard ratio per 6 g/day total fibre intake was 0.89 (95% confidence intervals: 0.81-0.99). Different findings were observed for haemorrhagic and ischaemic stroke in healthy-weight or overweight women. Total fibre, insoluble fibre and cereal fibre were inversely associated with haemorrhagic stroke risk in overweight/obese participants, and in healthy-weight women greater cereal fibre was associated with a lower ischaemic stroke risk. In non-hypertensive women, higher fibre density was associated with lower ischaemic stroke risk. Greater total fibre and fibre from cereals are associated with a lower stroke risk, and associations were more consistent with ischaemic stroke. The different observations by stroke type, body mass index group or hypertensive status indicates potentially different mechanisms.

  10. The role of the speech language pathologist in acute stroke

    Dilworth Cindy


    Full Text Available Dysphagia and communication impairment are common consequences of stroke. Stroke survivors with either or both of these impairments are likely to have poorer long-term outcomes than those who do not have them. Speech-language pathologists (SLP play a significant role in the screening, formal assessment, management, and rehabilitation of stroke survivors who present with dysphagia and/or communication impairment. Early diagnosis and referral is critical, as is intensive intervention as soon as the patient is able to participate. The SLP is also responsible for educating carers and staff in strategies that can support the patient and for making appropriate environmental modifications (e.g. altering diet consistencies or providing information in an aphasia-friendly format to optimize the stroke survivor′s participation, initially, in the rehabilitation program and, subsequently, within the community.

  11. Hearing Characteristics of Stroke Patients: Prevalence and Characteristics of Hearing Impairment and Auditory Processing Disorders in Stroke Patients. (United States)

    Koohi, Nehzat; Vickers, Deborah A; Lakshmanan, Rahul; Chandrashekar, Hoskote; Werring, David J; Warren, Jason D; Bamiou, Doris-Eva


    Stroke survivors may suffer from a range of hearing impairments that may restrict their participation in postacute rehabilitation programs. Hearing impairment may have a significant impact on listening, linguistic skills, and overall communication of the affected stroke patient. However, no studies sought to systematically characterize auditory function of stroke patients in detail, to establish the different types of hearing impairments in this cohort of patients. Such information would be clinically useful in understanding and addressing the hearing needs of stroke survivors. The present study aimed to characterize and classify the hearing impairments, using a detailed audiological assessment test battery, in order to determine the level of clinical need and inform appropriate rehabilitation for this patient population. A case-control study. Forty-two recruited stroke patients who were discharged from a stroke unit and 40 control participants matched for age. All participants underwent pure-tone audiometry and immittance measurements including acoustic reflex threshold, transient-evoked otoacoustic emissions, auditory-evoked brainstem response, and a central auditory processing assessment battery, performed in a single session. Hearing impairments were classified as peripheral hearing loss (cochlear and neural type), central auditory processing disorder (CAPD), and as a combination of CAPD and peripheral hearing loss. Overall mean hearing thresholds were not significantly different between the control and stroke groups. The most common type of hearing impairment in stroke patients was the combination type, "peripheral and CAPD," in the 61- to 80-yr-old subgroup (in 55%), and auditory processing deficits in 18- to 60-yr-olds (in 40%), which were both significantly higher than in controls. This is the first study to examine hearing function in detail in stroke patients. Given the importance of hearing for the efficiency of communication, it is essential to identify

    Full Text Available Purpose. People with stroke living in the community have an increased prevalence of depression and lower quality of life than healthy older adults. This cross-sectional observational study investigated whether participation in regular exercise was associated with improved mood and quality of life.Methods. We recruited three groups of community dwelling participants: 13 healthy older adults, 17 adults post-stroke who regularly participated in group exercise at a community fitness facility and 10 adults post-stroke who did not regularly exercise. We measured mood using the Depression, Anxiety, Stress Scale (DASS and quality of life using the Assessment of Quality of Life (AQoL scale.Results. Levels of stress and depression were significantly greater in the people with stroke who did not undertake regular exercise (p = 0.004 and p = 0.004 respectively, although this group had more recent strokes (p < 0.001. Both stroke groups had lower quality of life scores (p = 0.04 than the healthy adults.Conclusions. This small, community-based study confirms that people following stroke report poorer quality of life than stroke-free individuals. However, those who exercise regularly have significantly lower stress and depression compared to stroke survivors who do not. Future research should focus on the precise type and amount of exercise capable of improving mood following stroke.

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

    Quality improvement collaboratives are a popular model used to address gaps between evidence-based practice and patient care. Little is known about use of such collaboratives in emergency medical services, particularly for improving prehospital stroke care. To determine the feasibility of using this approach to improve prehospital stroke care, we conducted a pilot study of the Emergency Medical Services Stroke Quality Improvement Collaborative. Seventeen Massachusetts emergency medical service agencies participated in the quality improvement collaborative pilot project. We identified 5 prehospital stroke performance measures to assess the quality of prehospital care, guide collaborative activities, and monitor change in performance over time. During learning sessions, participants were trained in quality improvement and performance measurement, analyzed performance measure results, and shared successes and challenges. Focus groups were conducted to understand participants' experiences with the collaborative. Participating emergency medical service agencies collected stroke performance measures on 3,009 stroke patients during the pilot study. Adherence to 4 of 5 performance measures increased significantly over time. Participants acknowledged that the collaborative provided them with an efficient and effective framework for stroke quality improvement and peer-learning opportunities. As evidenced in Massachusetts, quality improvement collaboratives can be an effective tool to improve prehospital stroke care. The data collected, improvements made, participation of emergency medical service agencies, and positive experiences within the collaborative support the continued use of this approach.

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

    Simmons, Cailey; Noble, James M; Leighton-Herrmann, Ellyn; Hecht, Mindy F; Williams, Olajide


    Community-level determinants of stroke knowledge among children are unknown but could meaningfully impact public stroke education campaigns. We explored for associations between community- and school-level quality measures relative to baseline stroke knowledge among children participating in the Hip Hop Stroke program. Baseline stroke knowledge assessments were performed in 2839 fourth-, fifth-, and sixth-grade students (ages 9-11 years) from November 2005 to April 2014. Knowledge was assessed relative to school performance grade (SPG, graded A-F; a school-level measure determined by the New York City [NYC] Department of Education) and economic need index (ENI, range: 0-2; a community-level, within-school measure of subsidized housing and meals with higher scores indicating more socioeconomic distress). Schools studied included those with SPG = B (n = 196), SPG = C (n = 1590), and SPG = D (n = 1053) and mean ENI = .85 (standard deviation: .23). A composite assessment of knowledge, including 4 stroke symptoms (blurred vision, facial droop, sudden headache, and slurred speech), was conducted consistently since 2006. Overall, students correctly identified a mean of 1.74 stroke symptoms (95% confidence interval: 1.70-1.79; possible range: 0-4, expected value of chance response alone or no knowledge = 2). For quartiles of ENI, mean knowledge scores are as follows: ENI Q1  = 2.00, ENI Q2  = 2.09, ENI Q3  = 1.46, and ENI Q4  = 1.56 (ENI Q3 and ENI Q4 versus ENI Q1 , P < .001). For SPG, SPG = B schools: 2.09, SPG = C: 1.83, and SPG = D: 1.56 (SPG = C and SPG = D versus SPG = B schools, P ≤ .05). Children's stroke knowledge was lowest in NYC communities with greater economic need and lower school performance. These findings could guide stroke education campaign implementation strategies.

    Stroke patients with unknown onset (UKO) are excluded from thrombolytic therapy. We aim to study the safety and efficacy of intravenous alteplase in ischemic stroke patients with UKO of symptoms compared with those treated within 4.5 hours in a large cohort. Data were analyzed from 47 237 patients with acute ischemic stroke receiving intravenous tissue-type plasminogen activator in hospitals participating in the Safe Implementation of Treatment in Stroke-International Stroke Thrombolysis Registry between 2010 and 2014. Two groups were defined: (1) patients with UKO (n=502) and (2) patients treated within 4.5 hours of stroke onset (n=44 875). Outcome measures were symptomatic intracerebral hemorrhage per Safe Implementation of Treatment in Stroke on the 22 to 36 hours post-treatment neuroimaging and mortality and functional outcome assessed by the modified Rankin Scale at 3 months. Patients in UKO group were significantly older, had more severe stroke at baseline, and longer door-to-needle times than patients in the ≤4.5 hours group. Logistic regression showed similar risk of symptomatic intracerebral hemorrhage (adjusted odds ratio, 1.09; 95% confidence interval, 0.44-2.67) and no significant differences in functional independency (modified Rankin Scale score of 0-2; adjusted odds ratio, 0.79; 95% confidence interval, 0.56-1.10), but higher mortality (adjusted odds ratio, 1.58; 95% confidence interval, 1.04-2.41) in the UKO group compared with the ≤4.5 hours group. Patients treated within 4.5 hours showed reduced disability over the entire range of modified Rankin Scale compared with the UKO group (common adjusted odds ratio, 1.29; 95% confidence interval, 1.01-1.65). Our data suggest no excess risk of symptomatic intracerebral hemorrhage but increased mortality and reduced favorable outcome in patients with UKO stroke compared with patients treated within the approved time window. © 2017 American Heart Association, Inc.

  9. Anxiety After Stroke: The Importance of Subtyping. (United States)

    Chun, Ho-Yan Yvonne; Whiteley, William N; Dennis, Martin S; Mead, Gillian E; Carson, Alan J


    Anxiety after stroke is common and disabling. Stroke trialists have treated anxiety as a homogenous condition, and intervention studies have followed suit, neglecting the different treatment approaches for phobic and generalized anxiety. Using diagnostic psychiatric interviews, we aimed to report the frequency of phobic and generalized anxiety, phobic avoidance, predictors of anxiety, and patient outcomes at 3 months poststroke/transient ischemic attack. We followed prospectively a cohort of new diagnosis of stroke/transient ischemic attack at 3 months with a telephone semistructured psychiatric interview, Fear Questionnaire, modified Rankin Scale, EuroQol-5D5L, and Work and Social Adjustment Scale. Anxiety disorder was common (any anxiety disorder, 38 of 175 [22%]). Phobic disorder was the predominant anxiety subtype: phobic disorder only, 18 of 175 (10%); phobic and generalized anxiety disorder, 13 of 175 (7%); and generalized anxiety disorder only, 7 of 175 (4%). Participants with anxiety disorder reported higher level of phobic avoidance across all situations on the Fear Questionnaire. Younger age (per decade increase in odds ratio, 0.64; 95% confidence interval, 0.45-0.91) and having previous anxiety/depression (odds ratio, 4.38; 95% confidence interval, 1.94-9.89) were predictors for anxiety poststroke/transient ischemic attack. Participants with anxiety disorder were more dependent (modified Rankin Scale score 3-5, [anxiety] 55% versus [no anxiety] 29%; P anxiety] 19.5, 10-27 versus [no anxiety] 0, 0-5; P Anxiety after stroke/transient ischemic attack is predominantly phobic and is associated with poorer patient outcomes. Trials of anxiety intervention in stroke should consider the different treatment approaches needed for phobic and generalized anxiety. © 2018 The Authors.

  10. Interventions for motor apraxia following stroke. (United States)

    West, C; Bowen, A; Hesketh, A; Vail, A


    Apraxia is a cognitive disorder that can occur after stroke. It prevents a person from carrying out a learned movement. Various interventions are used to treat apraxia but evidence of their benefit has been lacking. To determine which therapeutic interventions targeted at motor apraxia reduce disability. We searched the Cochrane Stroke Group Trials Register (last searched November 2006). In addition, we searched the following databases: the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 3, 2006), MEDLINE (1966 to November 2007), EMBASE (1980 to November 2006), CINAHL (1982 to November 2006), PsycINFO (1974 to November 2006), the Research Index of the Occupational Therapy Journal (searched November 2006), REHABDATA (1956 to November 2006), the National Research Register (searched November 2006) and Current Controlled Trials Register (searched November 2006). We reviewed the reference lists of all articles that we identified as relevant. We made efforts to find both published and unpublished trials by writing to key authors and journals. Randomised controlled trials of therapeutic intervention for motor apraxia in stroke. One review author searched the titles, abstracts and keywords. Four review authors extracted data and analysed trial quality. We contacted investigators for further details of trials if necessary. Three trials including a total of 132 participants were included in the review. There was evidence of a small and short-lived therapeutic effect in the two studies that reported change in activities of daily living (102 participants) but this was not considered clinically significant and did not persist at the longer-term follow up. There is insufficient evidence to support or refute the effectiveness of specific therapeutic interventions for motor apraxia after stroke. Further research of higher quality is required. As we did not review whether patients with apraxia benefit from rehabilitation input in general, they

  16. Comparison of Medicare claims versus physician adjudication for identifying stroke outcomes in the Women's Health Initiative. (United States)

    Lakshminarayan, Kamakshi; Larson, Joseph C; Virnig, Beth; Fuller, Candace; Allen, Norrina Bai; Limacher, Marian; Winkelmayer, Wolfgang C; Safford, Monika M; Burwen, Dale R


    Many studies use medical record review for ascertaining outcomes. One large, longitudinal study, the Women's Health Initiative (WHI), ascertains strokes using participant self-report and subsequent physician review of medical records. This is resource-intensive. Herein, we assess whether Medicare data can reliably assess stroke events in the WHI. Subjects were WHI participants with fee-for-service Medicare. Four stroke definitions were created for Medicare data using discharge diagnoses in hospitalization claims: definition 1, stroke codes in any position; definition 2, primary position stroke codes; and definitions 3 and 4, hemorrhagic and ischemic stroke codes, respectively. WHI data were randomly split into training (50%) and test sets. A concordance matrix was used to examine the agreement between WHI and Medicare stroke diagnosis. A WHI stroke and a Medicare stroke were considered a match if they occurred within ±7 days of each other. Refined analyses excluded Medicare events when medical records were unavailable for comparison. Training data consisted of 24 428 randomly selected participants. There were 577 WHI strokes and 557 Medicare strokes using definition 1. Of these, 478 were a match. With regard to algorithm performance, specificity was 99.7%, negative predictive value was 99.7%, sensitivity was 82.8%, positive predictive value was 85.8%, and κ=0.84. Performance was similar for test data. Whereas specificity and negative predictive value exceeded 99%, sensitivity ranged from 75% to 88% and positive predictive value ranged from 80% to 90% across stroke definitions. Medicare data seem useful for population-based stroke research; however, performance characteristics depend on the definition selected.

  18. SPP retains interest in geothermal project

    International Nuclear Information System (INIS)

    Sobinkovic, B.


    Slovensky plynarensky priemysel (SPP) officially indicated that it intended to drop its project of using geothermal energy in the Kosicka kotlina. This spring it published an advert that it was looking for a company that wished to acquire a majority stake in the company, Geoterm Kosice. The company was established to commercially develop this geothermal source. But it seems SPP does not want to drop the project completely. It has kept some important cards, such as control over the land where the boreholes are located. Any company that wants to use geothermal energy needs a ruling issued by the Ministry of Environment defining the exploration area. Geothermal sources were found in the villages of Durkov, Svinica, Bidovce and Olsovany. Not so long ago the area was assigned to Geoterm but from May 9 2008 the area can be explored by Slovgeoterm. Both companies have the same majority shareholder - SPP. It controls 96% of Geoterm shares and 50% of Slovgeoterm. So far it has only officially announced its intention to sell the Geoterm shares. But as far as the use of the geothermal resource is concerned since May Slovgeoterm has played a key role.The company focuses on the utilization of geothermal energy. In addition to the project in the Kosice region, it has also participated in a project to heat more than a thousand flats using geothermal water in Galanta and a project to heat greenhouses in Podhajske. There are also other geothermal projects running in Presov and Michalovce. Icelandic company, Enex, with the same specialisation controls 28% of the company and a further 20% is owned by the investment group, NEFCO based in Helsinki. Two percent of the company is owned by its general director and the general proxy of Geoterm, Otto Halas. And so without the agreement of this company no-one can start any activities related to the utilization of geothermal energy. (authors)

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

  2. Recruiting and Retaining Patient-Caregiver-Nurse Triads for Qualitative Hospice Cancer Pain Research. (United States)

    Ehrlich, Olga; Walker, Rachel K


    Qualitative pain research for hospice patients with cancer and their caregivers involves recruiting and retaining participants with multiple vulnerabilities and ethical and logistical challenges. These have been reported for studies of individuals or dyads. However, there are no reports of the related challenges and outcomes where the sampled population was a hospice triad. Qualitative research about pain management for home hospice patients with cancer contributes rich descriptive data and such studies are critical to improving cancer pain outcomes. We describe the ethical and pragmatic challenges we faced in a study of the hospice caring triad, operationalized as the patient, family caregiver, and nurse; how our study design anticipated them; and related outcomes. We found that having an established relationship with the hospice agency at which we recruited participants, clearly identifying potential participants at the onset of hospice care, practice using a recruitment script, patient recruitment of caregivers, establishing rapport, and participants determining when interviews should end helped us recruit and retain our sample. We were unable to accrue our anticipated triad sample, partially because of nurse gatekeeping and the condition at admission of patient participants who enrolled but had physical decline or died prior to written consent. Although researchers will always face challenges to enrolling individuals and groups in cancer pain studies, with careful study design, recruitment, and retention planning and research team-participant engagement, it is possible to gather a robust corpus of qualitative data.

  6. Stroke prevention: an update. (United States)

    Bousser, Marie-Germaine


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

  7. Self-Reported Fatigue and Associated Factors Six Years after Stroke.

    Marie Elf

    Full Text Available Several studies have found that fatigue is one of the most commonly reported symptoms after stroke and the most difficult to cope with. The present study aimed to investigate the presence and severity of self-reported fatigue six years after stroke onset and associated factors. The cohort "Life After Stroke Phase I" (n = 349 persons was invited at six years to report fatigue (Fatigue Severity Scale 7-item version, perceived impact of stroke and global recovery after stroke (Stroke Impact Scale, anxiety and depression (Hospital Anxiety and Depression Scale, life satisfaction (Life Satisfaction Checklist and participation in everyday social activities (Frenchay Activities Index. At six years 37% of the 102 participants in this cross-sectional study reported fatigue. The results showed that in nearly all SIS domains the odds for post-stroke fatigue were higher in persons with a higher perceived impact. Furthermore, the odds for post-stroke fatigue were higher in those who had experienced a moderate/severe stroke and had signs of depression and anxiety. Fatigue is still present in one-third of persons as long as six years after stroke onset and is perceived to hinder many aspects of functioning in everyday life. There is an urgent need to develop and evaluate interventions to reduce fatigue.

    We describe a case of an unrecognized foreign body retained in the calcaneus. The patient denied any history of trauma. The skin overlying the calcaneus was intact with no local signs of inflammation. The retained foreign body was not observed on the radiograph of the calcaneus. Magnetic Resonance Imaging showed a tubular low signal intensity lesion in the calcaneal body, surrounded by strongly enhanced soft tissue and bone marrow edema caused by a foreign body reaction. A foreign body retained in the calcaneus was suspected on the basis of these findings. Surgical exploration and curettage was performed, and a rod shaped wooden fragment was found.

  9. Life after stroke in Appalachia

    Results: Five main themes emerged: 1 Frustration with new physical and functional impairment, 2 Negative emotions including anger, guilt, loneliness, and depression 3 Need for accessible support, 4 Longing for home during recovery and, 5 Stepping forward after stroke which included sub-themes of perseverance, acceptance, and retraining. Anger was described as contributing to delayed recover and emotional lability was described as a source of anger. The familiarity of home was viewed as key to reestablishing control over one's life. Survivors described how they developed perseverance to move forward and emphasized that willingness to participate in retraining led to adapting to impairments. Acceptance was described as letting go of prior expectations of self and others so one could live in the present.

    Low insulin-like growth factor 1 (IGF-1) has been associated with increased risk of atherosclerosis and atrial fibrillation in cross-sectional studies. Yet, prospective data linking IGF-1 levels to the development of ischemic stroke remain inconclusive. We examined prospectively the association between serum IGF-1 levels and incident ischemic stroke. We measured serum IGF-1 levels in 757 elderly individuals (mean age 79±5, 62% women), free of prevalent stroke, from the Framingham original cohort participants at the 22nd examination cycle (1990-1994) and were followed up for the development of ischemic stroke. Cox models were used to relate IGF-1 levels to the risk for incident ischemic stroke, adjusted for potential confounders. During a mean follow-up of 10.2 years, 99 individuals developed ischemic stroke. After adjustment for age, sex, and potential confounders, higher IGF-1 levels were associated with a lower risk of incident ischemic stroke, with subjects in the lowest quintile of IGF-1 levels having a 2.3-fold higher risk of incident ischemic stroke (95% confidence interval, 1.09-5.06; P =0.03) as compared with those in the top quintile. We observed an effect modification by diabetes mellitus and waist-hip ratio for the association between IGF-1 and ischemic stroke ( P risk of incident ischemic stroke, respectively. IGF-1 levels were inversely associated with ischemic stroke, especially among persons with insulin resistance. © 2017 American Heart Association, Inc.

  15. Time to rethink long-term rehabilitation management of stroke patients. (United States)

    Teasell, Robert; Mehta, Swati; Pereira, Shelialah; McIntyre, Amanda; Janzen, Shannon; Allen, Laura; Lobo, Liane; Viana, Ricardo


    It has long been assumed that stroke patients plateau in their recovery within 3 to 6 months of their stroke, and evidence for rehabilitation during the chronic stage is limited. As a consequence, rehabilitation resources for the management of chronic stroke are minimal. The primary objective was to identify randomized controlled trials (RCTs) across the continuum of stroke rehabilitation for interventions initiated 6 months or more following the onset of stroke. The secondary objective was to determine whether treatments provided post 6 moths are effective in improving outcomes among stroke survivors. Multiple databases were used to identify all RCTs published from 1970 to June 2012 in English language where the stroke interventions were initiated more than 6 months after the onset of the stroke. Data abstraction was performed using standardized data abstraction form that included general citation information, study participant characteristics, methodology, outcomes accessed, and overall findings. The results of our analysis revealed 339 RCTs. The mean number of subjects per study was 73. Two hundred fifty-six RCTs were related to motor recovery, 39 to cognitive function, and only 19 to psychosocial issues and community reintegration. The majority of the RCT s demonstrated a significant positive benefit. There is a robust evidence-base for stroke rehabilitation interventions in chronic stroke. This research synthesis reveals a paradox, whereby an impressive evidence-base contrasts with the limited optimism and resources available for rehabilitation in chronic stroke.

    Chaker, Layal; Baumgartner, Christine; den Elzen, Wendy P J


    OBJECTIVE: The objective was to determine the risk of stroke associated with subclinical hypothyroidism. DATA SOURCES AND STUDY SELECTION: Published prospective cohort studies were identified through a systematic search through November 2013 without restrictions in several databases. Unpublished...... studies were identified through the Thyroid Studies Collaboration. We collected individual participant data on thyroid function and stroke outcome. Euthyroidism was defined as TSH levels of 0.45-4.49 mIU/L, and subclinical hypothyroidism was defined as TSH levels of 4.5-19.9 mIU/L with normal T4 levels....... DATA EXTRACTION AND SYNTHESIS: We collected individual participant data on 47 573 adults (3451 subclinical hypothyroidism) from 17 cohorts and followed up from 1972-2014 (489 192 person-years). Age- and sex-adjusted pooled hazard ratios (HRs) for participants with subclinical hypothyroidism compared...

  17. Fractal gait patterns are retained after entrainment to a fractal stimulus. (United States)

    Rhea, Christopher K; Kiefer, Adam W; Wittstein, Matthew W; Leonard, Kelsey B; MacPherson, Ryan P; Wright, W Geoffrey; Haran, F Jay


    Previous work has shown that fractal patterns in gait can be altered by entraining to a fractal stimulus. However, little is understood about how long those patterns are retained or which factors may influence stronger entrainment or retention. In experiment one, participants walked on a treadmill for 45 continuous minutes, which was separated into three phases. The first 15 minutes (pre-synchronization phase) consisted of walking without a fractal stimulus, the second 15 minutes consisted of walking while entraining to a fractal visual stimulus (synchronization phase), and the last 15 minutes (post-synchronization phase) consisted of walking without the stimulus to determine if the patterns adopted from the stimulus were retained. Fractal gait patterns were strengthened during the synchronization phase and were retained in the post-synchronization phase. In experiment two, similar methods were used to compare a continuous fractal stimulus to a discrete fractal stimulus to determine which stimulus type led to more persistent fractal gait patterns in the synchronization and post-synchronization (i.e., retention) phases. Both stimulus types led to equally persistent patterns in the synchronization phase, but only the discrete fractal stimulus led to retention of the patterns. The results add to the growing body of literature showing that fractal gait patterns can be manipulated in a predictable manner. Further, our results add to the literature by showing that the newly adopted gait patterns are retained for up to 15 minutes after entrainment and showed that a discrete visual stimulus is a better method to influence retention.

  19. Factors Associated With Ischemic Stroke Survival and Recovery in Older Adults. (United States)

    Winovich, Divya Thekkethala; Longstreth, William T; Arnold, Alice M; Varadhan, Ravi; Zeki Al Hazzouri, Adina; Cushman, Mary; Newman, Anne B; Odden, Michelle C


    Little is known about factors that predispose older adults to poor recovery after a stroke. In this study, we sought to evaluate prestroke measures of frailty and related factors as markers of vulnerability to poor outcomes after ischemic stroke. In participants aged 65 to 99 years with incident ischemic strokes from the Cardiovascular Health Study, we evaluated the association of several risk factors (frailty, frailty components, C-reactive protein, interleukin-6, and cystatin C) assessed before stroke with stroke outcomes of survival, cognitive decline (≥5 points on Modified Mini-Mental State Examination), and activities of daily living decline (increase in limitations). Among 717 participants with incident ischemic stroke with survival data, slow walking speed, low grip strength, and cystatin C were independently associated with shorter survival. Among participants stroke. Inflammation, kidney function, and frailty also seemed to be determinants of survival and recovery after an ischemic stroke. These markers of vulnerability may identify targets for differing pre and poststroke medical management and rehabilitation among older adults at risk of poor stroke outcomes. © 2017 American Heart Association, Inc.

  20. Sex Differences in Neuromuscular Fatigability of the Knee Extensors Post-Stroke

    Directory of Open Access Journals (Sweden)

    Meghan Kirking


    Full Text Available Background and Purpose: Despite the implications of optimizing strength training post-stroke, little is known about the differences in fatigability between men and women with chronic stroke. The purpose of this study was to determine the sex differences in knee extensor muscle fatigability and potential mechanisms in individuals with stroke. Methods: Eighteen participants (10 men, eight women with chronic stroke (≥6 months and 23 (12 men, 11 women nonstroke controls participated in the study. Participants performed an intermittent isometric contraction task (6 s contraction, 3 s rest at 30% of maximal voluntary contraction (MVC torque until failure to maintain the target torque. Electromyography was used to determine muscle activation and contractile properties were assessed with electrical stimulation of the quadriceps muscles. Results: Individuals with stroke had a briefer task duration (greater fatigability than nonstroke individuals (24.1 ± 17 min vs. 34.9 ± 16 min. Men were more fatigable than women for both nonstroke controls and individuals with stroke (17.9 ± 9 min vs. 41.6 ± 15 min. Individuals with stroke had less fatigue-related changes in muscle contractile properties and women with stroke differed in their muscle activation strategy during the fatiguing contractions. Conclusions: Men and women fatigue differently post-stroke and this may be due to the way they neurally activate muscle groups.

  1. Study protocol: ICONS: identifying continence options after stroke: a randomised trial. (United States)

    Thomas, Lois H; Watkins, Caroline L; French, Beverley; Sutton, Christopher; Forshaw, Denise; Cheater, Francine; Roe, Brenda; Leathley, Michael J; Burton, Christopher; McColl, Elaine; Booth, Jo


    Urinary incontinence following acute stroke is common, affecting between 40%-60% of people in hospital after a stroke. Despite the availability of clinical guidelines for urinary incontinence and urinary incontinence after stroke, national audit data suggest incontinence is often poorly managed. Conservative interventions (e.g. bladder training, pelvic floor muscle training and prompted voiding) have been shown to have some effect with participants in Cochrane systematic reviews, but have not had their effectiveness demonstrated with stroke patients. A cluster randomised controlled pilot trial designed to assess the feasibility of a full-scale cluster randomised trial and to provide preliminary evidence of the effectiveness and cost-effectiveness of a systematic voiding programme for the management of continence after stroke. Stroke services will be randomised to receive the systematic voiding programme, the systematic voiding programme plus supported implementation, or usual care. The trial aims to recruit at least 780 participants in 12 stroke services (4 per arm). The primary outcome is presence/absence of incontinence at six weeks post-stroke. Secondary outcomes include frequency and severity of incontinence, quality of life and cost-utility. Outcomes will be measured at six weeks, three months and (for participants recruited in the first three months) twelve months after stroke. Process data will include rates of recruitment and retention and fidelity of intervention delivery. An integrated qualitative evaluation will be conducted in order to describe implementation and assist in explaining the potential mediators and modifiers of the process. ISRCTN: ISRCTN08609907

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

    Disability-adjusted life-years lost after stroke in Low & Middle-Income Countries (LMICs) is almost seven times those lost in High-income countries. Although individuals living with chronic neurological and mental disorders are prone to stigma, there is a striking paucity of literature on stroke-related stigma particularly from LMICs. To assess the prevalence, severity, determinants and psycho-social consequences of stigma among LMIC stroke survivors. Between November 2015 and February 2016, we conducted a cross-sectional survey of 200 consecutive stroke survivors attending a neurology clinic in a tertiary medical center in Ghana. The validated 8-Item Stigma Scale for Chronic Illness (SSCI-8) questionnaire was administered to study participants to assess internalized and enacted domains of stigma at the personal dimension with further adaptation to capture family and community stigma experienced by stroke participants. Responses on the SSCI-8 were scored from 1 to 5 for each item, where 1=never, 2=rarely, 3=sometimes, 4=often and 5=always with a score range of 8-40. Demographic and clinical data on stroke type and severity as well as depression and Health-Related Quality of Life indicators were also collected. Predictors of stroke-related stigma were assessed using Linear Models (GLM) via Proc GENMOD in SAS 9.4. 105 (52.5%) subjects recruited were males and the mean±SD age of stroke survivors in this survey was 62.0±14.4years. Mean SSCI-8 score was highest for personal stigma (13.7±5.7), which was significantly higher than family stigma (11.9±4.6; p=0.0005) and social/community stigma (11.4±4.4; pstigma. A graded increase in scores on the Geriatric Depression Scale and Centre for Epidemiological Studies-Depression scale was observed across the three categories. Living in an urban setting was associated with higher SSCI-8 scores. Moreover, stroke subjects with more severe post-stroke residual symptom deficits reported a significantly higher frequency of stigma

    Aim To examine how Australia, Singapore and the United States of America (USA) match to the World Stroke Organization Global Stroke Services health system monitoring indicators (HSI). Design Descriptive comparative study Participants The health systems of Australia, Singapore, the USA. Outcome measures Published data available from each country were mapped to the 10 health system monitoring indicators proposed by the World Stroke Organization. Results Most health system monitoring indicators were at least partially met in each country. Thrombolytic agents were available for use in acute stroke. Stroke guidelines and stroke registry data were available in all three countries. Stroke incidence, prevalence, and mortality rates were available but at non-uniform times post-stroke. The International Classification of Disease 9 or 10 coding systems are used in all three countries. Standardized clinical audits are routine in Australia and the USA, but not in Singapore. The use of the modified Rankin Scale is collected sub-acutely but not at one year post-stroke in all three countries. Conclusions The three developed countries are performing well against the World Stroke Organization health system monitoring indicators for acute and sub-acute stroke care. However, improvements in stroke risk assessment and at one-year post-stroke outcome measurement are needed.

  8. How are household economic circumstances affected after a stroke? The Psychosocial Outcomes In StrokE (POISE) Study. (United States)

    Essue, Beverley M; Hackett, Maree L; Li, Qiang; Glozier, Nick; Lindley, Richard; Jan, Stephen


    Stroke is associated with severe economic consequences. This is the first study to investigate in younger survivors the household economic burden of stroke. A multicenter, 3-year prospective cohort study was conducted of younger (18-65 years) survivors in Australia. Pre- and poststroke patterns of income and hardship were evaluated and multivariable logistic regression identified the predictors of economic hardship after stroke. Four hundred fourteen participants were followed up over 12 months after stroke. The variables that independently predicted economic hardship after stroke were: female (OR, 2.94; 95% CI, 1.52-5.70), hazardous alcohol consumption (OR, 2.28; 95% CI, 1.00-5.20), manual occupation (OR, 1.88; 95% CI, 1.07-3.30), lack of health insurance (OR, 2.01; 95% CI, 1.12-3.60), and prior hardship (OR, 3.93; 95% CI, 2.12-7.29), whereas concessional status (OR, 0.50; 95% CI, 0.26-0.95) and more social contacts per week (OR, 0.99; 95% CI, 0.98-1.00) reduced hardship likelihood. Higher prestroke income did not buffer hardship after stroke nor did clinical, health service, or disability factors. Policies to reduce inequalities after stroke would be best aimed at socioeconomic targets.

    measures. Two review authors independently selected trials, assessed trial quality, and extracted data. Disagreements were resolved by a third review author. Only one trial of 66 participants was included. In the acupuncture group, 12 out of 34 participants recovered to normal feeding (35.3%). In the control group, seven out of 32 participants recovered to normal feeding (21.9%). The relative risk of recovery was 1.61 with a 95% confidence interval of 0.73 to 3.58. No statistical significance was detected. There is not enough evidence to make any conclusion about the therapeutic effect of acupuncture for dysphagia after acute stroke. High quality and large scale randomised controlled trials are needed.

    Jean, Sherrie M; Preuss, Todd M; Sharma, Prachi; Anderson, Daniel C; Provenzale, James M; Strobert, Elizabeth; Ross, Stephen R; Stroud, Fawn C


    Over a 5-y period, 3 chimpanzees at our institution experienced cerebrovascular accidents (strokes). In light of the increasing population of aged captive chimpanzees and lack of literature documenting the prevalence and effectiveness of various treatments for stroke in chimpanzees, we performed a retrospective review of the medical records and necropsy reports from our institution. A survey was sent to other facilities housing chimpanzees that participate in the Chimpanzee Species Survival Plan to inquire about their experience with diagnosing and treating stroke. This case report describes the presentation, clinical signs, and diagnosis of stroke in 3 recent cases and in historical cases at our institution. Predisposing factors, diagnosis, and treatment options of cerebral vascular accident in the captive chimpanzee population are discussed also.

However, current evidence reveals that hemiparetic weakness impairs the capacity to perform, and practice, movements appropriately. Here we investigated how power training (i.e., high-intensity, dynamic resistance training affects recovery of upper-extremity motor function post-stroke. We hypothesized that power training, as a component of upper-extremity rehabilitation, would promote greater functional gains than functional task practice without deleterious consequences. Method Nineteen chronic hemiparetic individuals were studied using a crossover design. All participants received both functional task practice (FTP and HYBRID (combined FTP and power training in random order. Blinded evaluations performed at baseline, following each intervention block and 6-months post-intervention included: Wolf Motor Function Test (WMFT-FAS, Primary Outcome, upper-extremity Fugl-Meyer Motor Assessment, Ashworth Scale, and Functional Independence Measure. Neuromechanical function was evaluated using isometric and dynamic joint torques and concurrent agonist EMG. Biceps stretch reflex responses were evaluated using passive elbow stretches ranging from 60 to 180º/s and determining: EMG onset position threshold, burst duration, burst intensity and passive torque at each speed. Results Primary outcome: Improvements in WMFT-FAS were significantly greater following HYBRID vs. FTP (p = .049, regardless of treatment order. These functional improvements were retained 6-months post-intervention (p = .03. Secondary outcomes: A greater proportion of participants achieved minimally important differences (MID following HYBRID vs. FTP (p = .03. MIDs were retained 6-months post-intervention. Ashworth scores were unchanged (p > .05. Increased maximal isometric joint torque, agonist EMG and peak power were significantly greater following HYBRID vs. FTP (p p

  13. Ageism in stroke rehabilitation studies. (United States)

    Gaynor, Eva Joan; Geoghegan, Sheena Elizabeth; O'Neill, Desmond


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

  19. Knowledge, perceptions and thoughts of stroke among Arab-Muslim Israelis. (United States)

    Itzhaki, Michal; Koton, Silvia


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

  20. Facilities available in European hospitals treating stroke patients. (United States)

    Leys, Didier; Ringelstein, E Bernd; Kaste, Markku; Hacke, Werner


    Stroke units decrease mortality and need for institutional care, but they are not widely available. The objective of the study was to determine, among European hospitals admitting acute stroke patients, how many are able to provide an appropriate level of care. Method- We randomly selected 886 hospitals in 25 countries. We used definitions derived from a European expert survey for comprehensive stroke centers (CSC), primary stroke centers (PSC), and minimum level required for any hospital ward (AHW) admitting stroke patients. We determined the proportion of hospitals meeting criteria for each category, and which facilities were not available. Participating hospitals treated approximately one-third of all strokes supposed to have occurred in these countries in 2005. Forty-three (4.9%) met criteria for CSC, 32 (3.6%) for PSC, 356 (40.2%) for AHW, and 455 (51.4%) provided a lower level of care. In 2005, hospitals meeting criteria for CSC, PSC, AHW, and none of them admitted 27 644 (8.3%), 17 365 (5.2%), 146 175 (44.1%), and 140 306 (42.3%) patients. There was no 24-hour availability for brain CT scan in 25% of hospitals not meeting criteria for AHW. Of 448 hospitals admitting at least 1 stroke per day, 51 (11.4%) met criteria for PSC or CSC, and 227 (50.7%) for AHW. Less than 10% of European hospitals admitting acute stroke patients have optimal facilities, and in 40% even the minimum level is not available. Because the availability of facilities does not grant their use, our study suggests that only few acute stroke patients are treated in appropriate centers in Europe.

  1. Thrombolysis in Postoperative Stroke. (United States)

    Voelkel, Nicolas; Hubert, Nikolai Dominik; Backhaus, Roland; Haberl, Roman Ludwig; Hubert, Gordian Jan


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

  2. Imaging of Hemorrhagic Stroke. (United States)

    Hakimi, Ryan; Garg, Ankur


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

  3. MIDAS (Modafinil in Debilitating Fatigue After Stroke) (United States)

    Lillicrap, Thomas; Krishnamurthy, Venkatesh; Holliday, Elizabeth; Attia, John; Pagram, Heather; Nilsson, Michael; Parsons, Mark; Levi, Christopher R.


    Background and Purpose— This study aimed to assess the efficacy of modafinil, a wakefulness-promoting agent in alleviating post-stroke fatigue ≥3 months after stroke. We hypothesized that 200 mg of modafinil daily for 6 weeks would result in reduced symptoms of fatigue compared with placebo. Methods— This single-center phase 2 trial used a randomized, double-blind, placebo-controlled, crossover design. The key inclusion criterion was a multidimensional fatigue inventory score of ≥60. Patients were randomized to either modafinil or placebo for 6 weeks of therapy, then after a 1 week washout period swapped treatment arms for a second 6 weeks of therapy. The primary outcome was the multidimensional fatigue inventory; secondary outcomes included the Montreal cognitive assessment, the Depression, Anxiety, and Stress Scale (DASS), and the Stroke-Specific Quality of Life (SSQoL) scale. The multidimensional fatigue inventory is a self-administered questionnaire with a range of 0 to 100. Treatment efficacy was assessed using linear regression by estimating within-person, baseline-adjusted differences in mean outcomes after therapy. This trial was registered with the Australian New Zealand Clinical Trials Registry (ACTRN12615000350527). Results— A total of 232 stroke survivors were screened and 36 were randomized. Participants receiving modafinil reported a significant decrease in fatigue (multidimensional fatigue inventory, −7.38; 95% CI, −21.76 to −2.99; Pmodafinil therapy during the study period (P>0.05). Conclusions— Stroke survivors with nonresolving fatigue reported reduced fatigue and improved quality of life after taking 200 mg daily treatment with modafinil.

  5. Secular trends in ischemic stroke subtypes and stroke risk factors. (United States)

    Bogiatzi, Chrysi; Hackam, Daniel G; McLeod, A Ian; Spence, J David


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

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

    Stroke patients with mild-moderate upper extremity motor impairments and minimal sensory and cognitive deficits provide a useful model to study recovery and improve rehabilitation. Laboratory-based investigators use lesioning techniques for similar goals. To determine whether stroke lesions in an upper extremity rehabilitation trial cohort match lesions from the preclinical stroke recovery models used to drive translational research. Clinical neuroimages from 297 participants enrolled in the Interdisciplinary Comprehensive Arm Rehabilitation Evaluation (ICARE) study were reviewed. Images were characterized based on lesion type (ischemic or hemorrhagic), volume, vascular territory, depth (cortical gray matter, cortical white matter, subcortical), old strokes, and leukoaraiosis. Lesions were compared with those of preclinical stroke models commonly used to study upper limb recovery. Among the ischemic stroke participants, median infarct volume was 1.8 mL, with most lesions confined to subcortical structures (61%) including the anterior choroidal artery territory (30%) and the pons (23%). Of ICARE participants, stroke patients, but they represent a clinically and scientifically important subgroup. Compared with lesions in general stroke populations and widely studied animal models of recovery, ICARE participants had smaller, more subcortically based strokes. Improved preclinical-clinical translational efforts may require better alignment of lesions between preclinical and human stroke recovery models.

    Full Text Available Background. The aim of this study was to evaluate root displacement of the lower incisors fixed with FRC in different positions versus FSW retainers using the finite element method. Materials and Methods. 3D finite element models were designed for a mandibular anterior segment: Model 1: flexible spiral wire bonded to the lingual teeth surfaces, Model 2: FRC bonded to the upper third of lingual teeth surfaces, and Model 3: FRC bonded to the middle third. FE analysis was performed for three models and then tooth displacements were evaluated. Results. In contrast to lateral incisors and canines, the FSW retainer caused the central teeth to move more than the teeth bonded with FRC in both loadings. Comparison between Models 2 and 3 (in vertical loading showed that FRC retainers that bonded at the upper third of lingual teeth surfaces made central and canine teeth move less than FRC retainers bonded at the middle third; however, for lateral teeth it was the opposite. Conclusion. FRC retainers bonded at the upper third of lingual teeth surfaces make central and canine teeth move less than FRC retainers bonded at the middle third in vertical loading; however, for lateral teeth it was the opposite.

  18. Peripartal leukogram in cows with and without retained placenta

    Directory of Open Access Journals (Sweden)

    Lužajić Tijana


    Full Text Available The aim of this study was to investigate whether prepartal leukogram in cows with retained placenta could indicate the presence of subclinical systemic inflammatory response before the onset of disease. After calving, sixteen highly pregnant Holstein cows, aged 3 to 9 years, without clinical signs of the disease prior to calving were divided into two groups: the first group (n=9 were animals without retained placenta, or any visible inflammation after birth; the second group (n=7 were cows with retained placenta. Blood was sampled three times before parturition, at intervals of one week, and once 24 hours after birth. The number of total leukocytes, segmented and non segmented neutrophilic granulocytes (NG, lymphocytes and monocytes were determined by standard laboratory techniques. The results have shown that in the group of cows with retained placenta the number of mature neutrophils was slightly elevated in the third, second and last week before calving, and equal number of non segmented neutrophils in regard to the group with no retention. The results have also shown that, in both groups of cows, 24 hours after calving, the number of total leukocytes and the number of segmented neutrophils decreased, but the number of the non segmented neutrophils increased. Based on this, we can conclude that cows with retained placenta had no systemic inflammatory response during three weeks prepartal period, but 24 hours after calving, systemic inflammatory response was documented in all the cows. Moreover, the intensity of inflammatory response in cows with retained placenta was not more pronounced in comparison to cows without retained placenta.

  19. Stroke and renal dysfunction: are we always conscious of this relationship? (United States)

    Fabbian, Fabio; Casetta, Ilaria; De Giorgi, Alfredo; Pala, Marco; Tiseo, Ruana; Portaluppi, Francesco; Manfredini, Roberto


    Cerebrovascular disease may represent an important clinical presentation of atherosclerosis in chronic kidney disease (CKD), and atherosclerosis is frequently encountered in CKD. In fact, kidney disease is now considered a risk factor for development of cardiovascular disease. Although guidelines for primary prevention of stroke have been recently published, CKD is hardly mentioned. Based on a series of available studies, we analyzed the relationship between reduced renal function, end-stage renal disease (ESRD), and stroke. Reduced renal function and risk of stroke appear to be related to the highest risk of patients on dialysis treatment. Primary and secondary prevention of stroke should be encouraged in participants with renal dysfunction.

  20. Strength Training for Skeletal Muscle Endurance after Stroke. (United States)

    Ivey, Frederick M; Prior, Steven J; Hafer-Macko, Charlene E; Katzel, Leslie I; Macko, Richard F; Ryan, Alice S


    Initial studies support the use of strength training (ST) as a safe and effective intervention after stroke. Our previous work shows that relatively aggressive, higher intensity ST translates into large effect sizes for paretic and non-paretic leg muscle volume, myostatin expression, and maximum strength post-stroke. An unanswered question pertains to how our unique ST model for stroke impacts skeletal muscle endurance (SME). Thus, we now report on ST-induced adaptation in the ability to sustain isotonic muscle contraction. Following screening and baseline testing, hemiparetic stroke participants were randomized to either ST or an attention-matched stretch control group (SC). Those in the ST group trained each leg individually to muscle failure (20 repetition sets, 3× per week for 3 months) on each of three pneumatic resistance machines (leg press, leg extension, and leg curl). Our primary outcome measure was SME, quantified as the number of submaximal weight leg press repetitions possible at a specified cadence. The secondary measures included one-repetition maximum strength, 6-minute walk distance (6MWD), 10-meter walk speeds, and peak aerobic capacity (VO 2 peak). ST participants (N = 14) had significantly greater SME gains compared with SC participants (N = 16) in both the paretic (178% versus 12%, P muscle contraction, a metric that may carry more practical significance for stroke than the often reported measures of maximum strength.

  1. Long-term functional outcome of pediatric stroke survivors. (United States)

    Hurvitz, Edward; Warschausky, Seth; Berg, Michelle; Tsai, Shane


    To examine the long-term functional, psychosocial, and medical outcome of pediatric stroke survivors. This was a descriptive survey performed on patients with childhood stroke who participated in an earlier study. Measures included the Vineland Adaptive Behavior Scales (VABS) and the Diener Satisfaction with Life Scale. Current information on living situation, school placement, employment, and medical outcome were obtained. Twenty-nine (58%) patients participated. The mean age was 19.3 years (SD = 6.6), mean age of onset of stroke was 7.0 years (SD = 5.4), and mean follow-up time was 11.9 years (SD = 3.9). Diagnoses included hemorrhagic (31%) and ischemic (69%) stroke. All but one adult had finished high school, and the majority of participants had gone to college. 60% of patients over age 16 were employed. The average VABS levels for communication, daily living skills, socialization, and adaptive behavior fell into the moderately low range. Use of seizure medications and ADL dependence were the predictors for lower VABS levels (p life satisfaction. Patients who scored below adequate on VABS tended toward lower life satisfaction. Pediatric stroke survivors had good educational and mobility outcomes, but communication, ADL, and socialization fell into the low-moderate range. The different predictors of functional and subjective quality of life outcomes suggest that functional outcomes may mediate the relations between medical factors and satisfaction with life.

  2. Challenging comparison of stroke scales

    Directory of Open Access Journals (Sweden)

    Kavian Ghandehari


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

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

    Knapp, Peter; Campbell Burton, C Alexia; Holmes, John; Murray, Jenni; Gillespie, David; Lightbody, C Elizabeth; Watkins, Caroline L; Chun, Ho-Yan Y; Lewis, Sharon R


    Approximately 20% of stroke patients experience clinically significant levels of anxiety at some point after stroke. Physicians can treat these patients with antidepressants or other anxiety-reducing drugs, or both, or they can provide psychological therapy. This review looks at available evidence for these interventions. This is an update of the review first published in October 2011. The primary objective was to assess the effectiveness of pharmaceutical, psychological, complementary, or alternative therapeutic interventions in treating stroke patients with anxiety disorders or symptoms. The secondary objective was to identify whether any of these interventions for anxiety had an effect on quality of life, disability, depression, social participation, caregiver burden, or risk of death. We searched the trials register of the Cochrane Stroke Group (January 2017). We also searched the Cochrane Central Register of Controlled Trials (CENTRAL; the Cochrane Library; 2017, Issue 1: searched January 2017); MEDLINE (1966 to January 2017) in Ovid; Embase (1980 to January 2017) in Ovid; the Cumulative Index to Nursing and Allied Health Literature (CINAHL; 1937 to January 2017) in EBSCO; and PsycINFO (1800 to January 2017) in Ovid. We conducted backward citation searches of reviews identified through database searches and forward citation searches of included studies. We contacted researchers known to be involved in related trials, and we searched clinical trials registers for ongoing studies. We included randomised trials including participants with a diagnosis of both stroke and anxiety for which treatment was intended to reduce anxiety. Two review authors independently screened and selected titles and abstracts for inclusion. Two review authors independently extracted data and assessed risk of bias. We performed a narrative review. We planned to do a meta-analysis but were unable to do so as included studies were not sufficiently comparable. We included three trials (four

    Having a small social network and lack of social support have been associated with incident coronary heart disease; however, epidemiological evidence for incident stroke is limited. We assessed the longitudinal association of a small social network and lack of social support with risk of incident stroke and evaluated whether the association was partly mediated by vital exhaustion and inflammation. The Atherosclerosis Risk in Communities study measured social network and social support in 13 686 men and women (mean, 57 years; 56% women; 24% black; 76% white) without a history of stroke. Social network was assessed by the 10-item Lubben Social Network Scale and social support by a 16-item Interpersonal Support Evaluation List-Short Form. During a median follow-up of 18.6 years, 905 incident strokes occurred. Relative to participants with a large social network, those with a small social network had a higher risk of stroke (hazard ratio [95% confidence interval], 1.44 [1.02-2.04]) after adjustment for demographics, socioeconomic variables, marital status, behavioral risk factors, and major stroke risk factors. Vital exhaustion, but not inflammation, partly mediated the association between a small social network and incident stroke. Social support was unrelated to incident stroke. In this sample of US community-dwelling men and women, having a small social network was associated with excess risk of incident stroke. As with other cardiovascular conditions, having a small social network may be associated with a modestly increased risk of incident stroke. © 2014 American Heart Association, Inc.

    Sowtali, Siti Noorkhairina; Yusoff, Dariah Mohd; Harith, Sakinah; Mohamed, Monniaty


    To date, there is a lack of published studies on assessment tools to evaluate the effectiveness of stroke education programs. This study developed and validated the Malay language version of the Stroke Knowledge Test research instrument. This study involved translation, validity, and reliability phases. The instrument underwent backward and forward translation of the English version into the Malay language. Nine experts reviewed the content for consistency, clarity, difficulty, and suitability for inclusion. Perceived usefulness and utilization were obtained from experts' opinions. Later, face validity assessment was conducted with 10 stroke patients to determine appropriateness of sentences and grammar used. A pilot study was conducted with 41 stroke patients to determine the item analysis and reliability of the translated instrument using the Kuder Richardson 20 or Cronbach's alpha. The final Malay version Stroke Knowledge Test included 20 items with good content coverage, acceptable item properties, and positive expert review ratings. Psychometric investigations suggest that Malay version Stroke Knowledge Test had moderate reliability with Kuder Richardson 20 or Cronbach's alpha of 0.58. Improvement is required for Stroke Knowledge Test items with unacceptable difficulty indices. Overall, the average rating of perceived usefulness and perceived utility of the instruments were both 72.7%, suggesting that reviewers were likely to use the instruments in their facilities. Malay version Stroke Knowledge Test was a valid and reliable tool to assess educational needs and to evaluate stroke knowledge among participants of group-based stroke education programs in Malaysia.

  8. Investigation of Stability Alarming for Retaining Wall Structures with Damage

    Directory of Open Access Journals (Sweden)

    Qian Xu


    Full Text Available To warn of the stability of retaining wall structures with damage, a simplified mechanical model and a finite element model of this retaining wall-soil coupling system are established. Via finite element model updating, a baseline finite element model of the wall-soil system is acquired. A damage alarming index ERSD (Energy Ratio Standard Deviation is proposed via the wavelet packet analysis of a virtual impulse response function of dynamic responses to this baseline finite element model. The internal relationships among the alarming index, earth pressure, and damage stability of the wall are analyzed. Then, a damage stability alarming method for the retaining walls is advanced. To verify the feasibility and validity of this alarming method, vibration tests on the baseline finite element model of a pile plate retaining wall are performed. The ERSD is used as an alarm for the damage stability of the wall. Analysis results show that, with an increase in the ERSD, the stability of the wall changes from a stable state to an unstable one. The wall reaches a critical stable state when the alarming index reaches its threshold value. Thus, the damage stability of this pile plate retaining wall can be alarmed via ERSD.

  9. Seismic analysis for translational failure of landfills with retaining walls. (United States)

    Feng, Shi-Jin; Gao, Li-Ya


    In the seismic impact zone, seismic force can be a major triggering mechanism for translational failures of landfills. The scope of this paper is to develop a three-part wedge method for seismic analysis of translational failures of landfills with retaining walls. The approximate solution of the factor of safety can be calculated. Unlike previous conventional limit equilibrium methods, the new method is capable of revealing the effects of both the solid waste shear strength and the retaining wall on the translational failures of landfills during earthquake. Parameter studies of the developed method show that the factor of safety decreases with the increase of the seismic coefficient, while it increases quickly with the increase of the minimum friction angle beneath waste mass for various horizontal seismic coefficients. Increasing the minimum friction angle beneath the waste mass appears to be more effective than any other parameters for increasing the factor of safety under the considered condition. Thus, selecting liner materials with higher friction angle will considerably reduce the potential for translational failures of landfills during earthquake. The factor of safety gradually increases with the increase of the height of retaining wall for various horizontal seismic coefficients. A higher retaining wall is beneficial to the seismic stability of the landfill. Simply ignoring the retaining wall will lead to serious underestimation of the factor of safety. Besides, the approximate solution of the yield acceleration coefficient of the landfill is also presented based on the calculated method. Copyright © 2010 Elsevier Ltd. All rights reserved.

  12. British Association of Stroke Physicians: benchmarking survey of stroke services. (United States)

    Rodgers, Helen; Dennis, Martin; Cohen, David; Rudd, Anthony


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

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

  14. [Smoking and stroke]. (United States)

    Hashimoto, Yoichiro


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

  17. The stability of gabion walls for earth retaining structures

    Directory of Open Access Journals (Sweden)

    Mahyuddin Ramli


    Full Text Available The stability of earth retaining structures in flood prone areas has become a serious problem in many countries. The two most basic causes of failure arising from flooding are scouring and erosion of the foundation of the superstructure. Hence, a number of structures like bridges employ scour-arresting devices, e.g., gabions to acting on the piers and abutments during flooding. Research was therefore undertaken to improve gabion resistance against lateral movement by means of an interlocking configuration instead of the conventional stack-and-pair system. This involved simulating lateral thrusts against two dimensionally identical retaining wall systems configured according to the rectangular and hexagonal gabion type. The evolution of deformation observed suggested that the interlocking design exhibits better structural integrity than the conventional box gabion-based wall in resisting lateral movement and therefore warrants consideration for use as an appropriate scour-arresting device for earth retaining structures.

  18. Sleep Parameters, Functional Status, and Time Post-Stroke are Associated with Offline Motor Skill Learning in People with Chronic Stroke. (United States)

    Siengsukon, Catherine; Al-Dughmi, Mayis; Al-Sharman, Alham; Stevens, Suzanne


    Mounting evidence demonstrates that individuals with stroke benefit from sleep to enhance learning of a motor task. While stage NREM2 sleep and REM sleep have been associated with offline motor skill learning in neurologically intact individuals, it remains unknown which sleep parameters or specific sleep stages are associated with offline motor skill learning in individuals with stroke. Twenty individuals with chronic stroke (>6 months following stroke) and 10 control participants slept for three consecutive nights in a sleep laboratory with polysomnography. Participants practiced a tracking task the morning before the third night and underwent a retention test the morning following the third night. Offline learning on the tracking task was assessed. Pearson's correlations assessed for associations between the magnitude of offline learning and sleep variables, age, upper-extremity motor function, stroke severity, depression, and time since stroke occurrence. Individuals with stroke performed with significantly less error on the tracking task following a night of sleep (p = 0.006) while the control participants did not (p = 0.816). Increased sleep efficiency (r = -0.285), less time spent in stage NREM3 sleep (r = 0.260), and more time spent in stage REM sleep (r = -0.266) were weakly-to-moderately associated with increased magnitude of offline motor learning. Furthermore, higher upper-extremity motor function (r = -0.400), lower stroke severity (r = 0.360), and less time since stroke occurrence (r = 0.311) were moderately associated with increased magnitude of offline motor learning. This study is the first study to provide insight into which sleep stages and individual characteristics may be associated with offline learning in people with stroke. Further research is needed to delineate which factors or combination of factors promote offline motor learning in people with neurologic injury to best promote motor recovery in these

  19. Homocysteine lowering for stroke prevention: Unravelling the complexity of the evidence. (United States)

    Spence, J David


    Elevated levels of total homocysteine impair endothelial dysfunction and increase thrombosis. Homocysteine is causal in animal models, and in human studies, elevated total homocysteine is significantly associated with carotid atherosclerosis, lacunar infarction, and markedly increased risk of stroke in atrial fibrillation. Because two of the early large trials of B vitamin therapy (Vitamin Intervention for Stroke Prevention and the Norwegian Vitamin Study) did not show any reduction of stroke, and the Heart Outcomes Prevention Evaluation 2 trial was mistakenly interpreted as not showing a reduction of stroke (because the authors could not think of a biological difference between stroke and myocardial infarction), there has been widespread pessimism regarding treatment to lower total homocysteine for stroke prevention. However, the Heart Outcomes Prevention Evaluation 2 trial, the French trial of folic acid and omega three oils, the Vitamins to Prevent Stroke subgroup excluding antiplatelet therapy all showed a significant reduction of stroke. Reasons why the Vitamin Intervention for Stroke Prevention trial were negative included folate fortification in North America, provision of injections of B12 to patients with low baseline serum B12, and as it turns out, harm from cyanide in cyanocobalamin among participants with impaired renal function. In the Diabetic Intervention with Vitamins in Nephropathy trial, B vitamins including cyanocobalamin were harmful, and in a Vitamin Intervention for Stroke Prevention subgroup excluding participants who received B12 injections and those with impaired renal function, there was a statistically significant reduction of stroke/myocardial infarction/vascular death. In 2015, the China Stroke Primary Prevention Trial (CSPPT), in over 20,000 participants followed for 5 years, showed a significant reduction of stroke with folic acid in a setting where folate fortification has not been implemented.

  20. Life after Stroke in an Urban Minority Population: A Photovoice Project

    Directory of Open Access Journals (Sweden)

    Revathi Balakrishnan


    Full Text Available Stroke is a leading cause of disability in the United States and disproportionately affects minority populations. We sought to explore the quality of life in urban, minority stroke survivors through their own photos and narratives. Using the Photovoice method, seventeen stroke survivors were instructed to take pictures reflecting their experience living with and recovering from stroke. Key photographs were discussed in detail; participants brainstormed ways to improve their lives and presented their work in clinical and community sites. Group discussions were recorded, transcribed, and coded transcripts were reviewed with written narratives to identify themes. Participants conveyed recovery from stroke in three stages: learning to navigate the initial physical and emotional impact of the stroke; coping with newfound physical and emotional barriers; and long-term adaptation to physical impairment and/or chronic disease. Participants navigated this stage-based model to varying degrees of success and identified barriers and facilitators to this process. Barriers included limited access for disabled and limited healthy food choices unique to the urban setting; facilitators included presence of social support and community engagement. Using Photovoice, diverse stroke survivors were able to identify common challenges in adapting to life after stroke and important factors for recovery of quality of life.

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

  3. Problematising risk in stroke rehabilitation. (United States)

    Egan, Mary Y; Kessler, Dorothy; Ceci, Christine; Laliberté-Rudman, Debbie; McGrath, Colleen; Sikora, Lindsey; Gardner, Paula


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

  4. Validation of a stroke symptom questionnaire for epidemiological surveys. (United States)

    Abe, Ivana Makita; Goulart, Alessandra Carvalho; Santos Júnior, Waldyr Rodrigues; Lotufo, Paulo Andrade; Benseñor, Isabela Martins


    Stroke is a relevant issue within public health and requires epidemiological surveillance tools. The aim here was to validate a questionnaire for evaluating individuals with stroke symptoms in the Stroke Morbidity and Mortality Study (Estudo de Mortalidade e Morbidade do Acidente Vascular Cerebral, EMMA), São Paulo, Brazil. This was a cross-sectional study performed among a sample of the inhabitants of Butantã, an area in the western zone of the city of São Paulo. For all households in the coverage area of a primary healthcare unit, household members over the age of 35 years answered a stroke symptom questionnaire addressing limb weakness, facial weakness, speech problems, sensory disorders and impaired vision. Thirty-six participants were randomly selected for a complete neurological examination (gold standard). Considering all the questions in the questionnaire, the sensitivity was 72.2%, specificity was 94.4%, positive predictive value was 92.9% and negative predictive value was 77.3%. The positive likelihood ratio was 12.9, the negative likelihood ratio was 0.29 and the kappa coefficient was 0.67. Limb weakness was the most sensitive symptom, and speech problems were the most specific. The stroke symptom questionnaire is a useful tool and can be applied by trained interviewers with the aim of identifying community-dwelling stroke patients, through the structure of the Family Health Program.

  5. Important factors influencing the return to work after stroke. (United States)

    Wang, Ying-Chih; Kapellusch, Jay; Garg, Arun


    As the field of rehabilitation shifts its focus towards improving functional capacity instead of managing disability, return to work (RTW) and return to the community emerge as key goals in a person's recovery from major disabling illness such as stroke. To compile important factors believed to influence RTW after a stroke. Based on a comprehensive literature review, we clustered similar factors and organized these factors based on the International Classification of Function, Disability and Health (ICF) framework: body functions or structure, activity participation, environmental factors and personal and psychosocial factors. Overall, stroke severity, as assessed by the degree of residual disability such as weakness, neurological deficit or impairments (speech, cognition, apraxia, agnosia), has been shown to be the most consistent negative predictor of RTW. Many factors such as the number of working years remaining until retirement, depression, medical history, and occupation need to be taken into consideration for stroke survivors, as they can influence RTW decision making. Stroke survivors who are flexible and realistic in their vocational goal and emotionally accept their disability appear more likely to return to work. There are many barriers to employment for stroke survivors ranging from physical and cognitive impairments to psychosocial and environmental factors.

  6. Thrombolysis in acute ischemic stroke: where and when?

    Directory of Open Access Journals (Sweden)

    Giuseppe Micieli


    Full Text Available The therapy of acute ischemic stroke remains an open challenge for the clinicians and is closely connected to the ready acknowledgment of symptoms, to the promptness of the instrumental diagnosis and consequently to the rapidity of the pharmacological intervention. Although several studies have validated the effectiveness and the safety profileof the intravenous fibrinolytic treatment, the number of patients who benefit of such therapeutic opportunity is still too little. This data is partially due to the delay within patients arrive to the hospital and to the doubts of the physicians on the possible collateral effects, but it is also related to logistic and organizational-managerial problematic of the patient with acute stroke.These last ones mainly derive from the deficiency on the national territory of dedicated structures (Stroke Unit, from the absence of operative connections between the 118-service and the Stroke Unit, from the delay of the neurologist calling in the emergency room that does not allow an adapted diagnostic evaluation of the ischemic event. The spread of the intravenous fibrinolysis must therefore necessarily pass through the creation of participation protocols between hospitals with stroke unit and primary aid, and between department of emergency/ urgency and staff of the stroke unit also previewing the creation of professional figures like those of the urgency neurologist that could have the full right of the management and the treatment of cerebral ischemic pathology.

  7. Spatial cognitive rehabilitation and motor recovery after stroke (United States)

    Barrett, A.M.; Muzaffar, Tufail


    Purpose of review Stroke rehabilitation needs to take major steps forward to reduce functional disability for survivors. In this article, we suggest that spatial retraining might greatly increase the efficiency and efficacy of motor rehabilitation, directly addressing the burden and cost of paralysis after stroke. Recent findings Combining motor and cognitive treatment may be practical, as well as addressing needs after moderate–to-severe stroke. Spatial neglect could suppress motor recovery and reduce motor learning, even when patients receive appropriate rehabilitation to build strength, dexterity, and endurance. Spatial neglect rehabilitation acts to promote motor as well as visual-perceptual recovery. These findings, and previous underemphasized studies, make a strong case for combining spatial neglect treatment with traditional exercise training. Spatial neglect therapies might also help people who cannot participate in intensive movement therapies because of limited strength and endurance after stroke. Summary Spatial retraining, currently used selectively after right brain stroke, may be broadly useful after stroke to promote rapid motor recovery. PMID:25364954

  8. Abnormal P-Wave Axis and Ischemic Stroke: The ARIC Study (Atherosclerosis Risk In Communities). (United States)

    Maheshwari, Ankit; Norby, Faye L; Soliman, Elsayed Z; Koene, Ryan J; Rooney, Mary R; O'Neal, Wesley T; Alonso, Alvaro; Chen, Lin Y


    Abnormal P-wave axis (aPWA) has been linked to incident atrial fibrillation and mortality; however, the relationship between aPWA and stroke has not been reported. We hypothesized that aPWA is associated with ischemic stroke independent of atrial fibrillation and other stroke risk factors and tested our hypothesis in the ARIC study (Atherosclerosis Risk In Communities), a community-based prospective cohort study. We included 15 102 participants (aged 54.2±5.7 years; 55.2% women; 26.5% blacks) who attended the baseline examination (1987-1989) and without prevalent stroke. We defined aPWA as any value outside 0 to 75° using 12-lead ECGs obtained during study visits. Each case of incident ischemic stroke was classified in accordance with criteria from the National Survey of Stroke by a computer algorithm and adjudicated by physician review. Multivariable Cox regression was used to estimate hazard ratios and 95% confidence intervals for the association of aPWA with stroke. During a mean follow-up of 20.2 years, there were 657 incident ischemic stroke cases. aPWA was independently associated with a 1.50-fold (95% confidence interval, 1.22-1.85) increased risk of ischemic stroke in the multivariable model that included atrial fibrillation. When subtyped, aPWA was associated with a 2.04-fold (95% confidence interval, 1.42-2.95) increased risk of cardioembolic stroke and a 1.32-fold (95% confidence interval, 1.03-1.71) increased risk of thrombotic stroke. aPWA is independently associated with ischemic stroke. This association seems to be stronger for cardioembolic strokes. Collectively, our findings suggest that alterations in atrial electric activation may predispose to cardiac thromboembolism independent of atrial fibrillation. © 2017 American Heart Association, Inc.

Eight stroke network facilitators (SNFs were appointed in selected hospitals to enable the establishment of stroke units, develop thrombolysis services, and implement protocols. We aimed to explain the main issues being faced by clinicians in providing evidence-based stroke care, and to determine if the appointment of an SNF was perceived as an acceptable strategy to improve stroke care. Face-to-face semistructured interviews were used in a qualitative research design. Interview transcripts were verified by respondents prior to coding. Two researchers conducted thematic analysis of major themes and subthemes. Overall, 84 hospital staff participated in 33 interviews during 2008. The common factors found to impact on stroke care included staff and equipment availability, location of care, inconsistent use of clinical pathways, and professional beliefs. Other barriers included limited access to specialist clinicians and workload demands. The establishment of dedicated stroke units was considered essential to improve the quality of care. The SNF role was valued for identifying gaps in care and providing capacity to change clinical processes. This is the first large, qualitative multicenter study to

    Morgenstern, Lewis B; Sánchez, Brisa N; Skolarus, Lesli E; Garcia, Nelda; Risser, Jan M H; Wing, Jeffrey J; Smith, Melinda A; Zahuranec, Darin B; Lisabeth, Lynda D


    We sought to describe the association of spirituality, optimism, fatalism, and depressive symptoms with initial stroke severity, stroke recurrence, and poststroke mortality. Stroke cases from June 2004 to December 2008 were ascertained in Nueces County, TX. Patients without aphasia were queried on their recall of depressive symptoms, fatalism, optimism, and nonorganizational spirituality before stroke using validated scales. The association between scales and stroke outcomes was studied using multiple linear regression with log-transformed National Institutes of Health Stroke Scale and Cox proportional hazards regression for recurrence and mortality. Six hundred sixty-nine patients participated; 48.7% were women. In fully adjusted models, an increase in fatalism from the first to third quartile was associated with all-cause mortality (hazard ratio, 1.41; 95% CI, 1.06-1.88) and marginally associated with risk of recurrence (hazard ratio, 1.35; 95% CI, 0.97-1.88), but not stroke severity. Similarly, an increase in depressive symptoms was associated with increased mortality (hazard ratio, 1.32; 95% CI, 1.02-1.72), marginally associated with stroke recurrence (HR, 1.22; 95% CI, 0.93-1.62), and with a 9.0% increase in stroke severity (95% CI, 0.01-18.0). Depressive symptoms altered the fatalism-mortality association such that the association of fatalism and mortality was more pronounced for patients reporting no depressive symptoms. Neither spirituality nor optimism conferred a significant effect on stroke severity, recurrence, or mortality. Among patients who have already had a stroke, self-described prestroke depressive symptoms and fatalism, but not optimism or spirituality, are associated with increased risk of stroke recurrence and mortality. Unconventional risk factors may explain some of the variability in stroke outcomes observed in populations and may be novel targets for intervention.

  11. Mendelian Genes and Risk of Intracerebral Hemorrhage and Small-Vessel Ischemic Stroke in Sporadic Cases. (United States)

    Chong, Michael; O'Donnell, Martin; Thijs, Vincent; Dans, Antonio; López-Jaramillo, Patricio; Gómez-Arbeláez, Diego; Mondo, Charles; Czlonkowska, Anna; Skowronska, Marta; Oveisgharan, Shahram; Yusuf, Salim; Paré, Guillaume


    Mendelian strokes are rare genetic disorders characterized by early-onset small-vessel stroke. Although extensively studied among families with syndromic features, whether these genes affect risk among sporadic cases is unknown. We sequenced 8 genes responsible for Mendelian stroke in a case-control study of sporadic stroke cases (≤70 years). Participants included 1251 primary stroke cases of small-vessel pathology (637 intracerebral hemorrhage and 614 small-vessel ischemic stroke cases) and 1716 controls from the INTERSTROKE study (Study of the Importance of Conventional and Emerging Risk Factors of Stroke in Different Regions and Ethnic Groups of the World). Overall, the prevalence of canonical disease-causing mutations was 0.56% in cases and 0.23% in controls (odds ratio=1.89; 95% confidence interval, 0.54-7.57; P =0.33). CADASIL (Cerebral Autosomal Dominant Arteriopathies with Subcortical Infarcts and Leukoencephalopathies) mutations were more frequent among cases (0.48%) than controls (0.23%) but were not significantly associated with stroke risk (odds ratio=2.03; 95% confidence interval, 0.58-8.02; P =0.27). Next, we included all rare nonsynonymous mutations to investigate whether other types of mutations may contribute to stroke risk. Overall, 13.5% of cases and 14.2% of controls were carriers of at least one rare nonsynonymous mutation among the 8 Mendelian stroke genes. Mutation carriers were not at elevated risk of stroke (odds ratio=0.93; 95% confidence interval, 0.75-1.16; P =0.55). In the absence of syndromic features and family history of stroke, screening for Mendelian mutations among small-vessel stroke patients is unlikely to have high diagnostic utility. © 2017 American Heart Association, Inc.

    Despite increased staff engagement and improved new hire on-boarding, organizations struggle to retain millennial nurses. One dominant trait is shared by organizations that have successfully reduced turnover for this group: investment in select strategies that cement loyalty to the organization. In this article, the authors describe 2 strategies for retaining early-tenure millennial nurses. In the 1st article of this series, the authors described why nursing leaders must supplement their organization's current investments in engagement with strategies targeted at millennials in their 1st 3 years. This 2nd part of the series will outline these strategies.

  14. Uncertainty in retained austenite measurements applied to individual crystallographic orientations (United States)

    Creuziger, A.; Gnäupel-Herold, T.


    A technique to measure the phase volume fraction of an individual orientation and the uncertainty in the measurement is demonstrated in this paper. The technique of complete pole figure averaging using neutron diffraction was used to assess the phase fraction of retained austenite in transformation induced plasticity (TRIP) steels and quantify the uncertainty in the phase fraction. In parallel, an ensemble of orientation distribution functions was calculated to assess crystallographic volume fractions of particular orientations and the uncertainty of these volume fractions using Monte Carlo techniques. These methods were combined to measure the retained austenite phase volume fraction of an individual orientation.

  20. Burden of stroke in Cambodia. (United States)

    Loo, Keat Wei; Gan, Siew Hua


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

  2. Stroke scale score and early prediction of outcome after stroke

    International Nuclear Information System (INIS)

    Ahmed, R.; Zuberi, F.Z.; Afsar, S.


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

  3. Identification of stroke mimics among clinically diagnosed acute strokes. (United States)

    Tuntiyatorn, Lojana; Saksornchai, Pichaya; Tunlayadechanont, Supoch


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

  4. Acute single channel EEG predictors of cognitive function after stroke.

    Directory of Open Access Journals (Sweden)

    Anna Aminov

    Full Text Available Early and accurate identification of factors that predict post-stroke cognitive outcome is important to set realistic targets for rehabilitation and to guide patients and their families accordingly. However, behavioral measures of cognition are difficult to obtain in the acute phase of recovery due to clinical factors (e.g. fatigue and functional barriers (e.g. language deficits. The aim of the current study was to test whether single channel wireless EEG data obtained acutely following stroke could predict longer-term cognitive function.Resting state Relative Power (RP of delta, theta, alpha, beta, delta/alpha ratio (DAR, and delta/theta ratio (DTR were obtained from a single electrode over FP1 in 24 participants within 72 hours of a first-ever stroke. The Montreal Cognitive Assessment (MoCA was administered at 90-days post-stroke. Correlation and regression analyses were completed to identify relationships between 90-day cognitive function and electrophysiological data, neurological status, and demographic characteristics at admission.Four acute qEEG indices demonstrated moderate to high correlations with 90-day MoCA scores: DTR (r = -0.57, p = 0.01, RP theta (r = 0.50, p = 0.01, RP delta (r = -0.47, p = 0.02, and DAR (r = -0.45, p = 0.03. Acute DTR (b = -0.36, p < 0.05 and stroke severity on admission (b = -0.63, p < 0.01 were the best linear combination of predictors of MoCA scores 90-days post-stroke, accounting for 75% of variance.Data generated by a single pre-frontal electrode support the prognostic value of acute DAR, and identify DTR as a potential marker of post-stroke cognitive outcome. Use of single channel recording in an acute clinical setting may provide an efficient and valid predictor of cognitive function after stroke.

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

  6. Influence of Sociodemographic and Stroke-related Factors on Availability of Social Support among Nigerian Stroke Survivors. (United States)

    Vincent-Onabajo, G O; Muhammad, M M; Ali, M Usman; Masta, M Ali


    Availability of social support has been identified as an important prerequisite for positive outcomes after stroke. There is however, little information on variables that influence the availability of social support after stroke. This study explored the influence of selected sociodemographic and clinical variables on social support of stroke survivors in Nigeria. One hundred stroke survivors undergoing rehabilitation at two tertiary-care hospitals in Northern Nigeria participated in the study. Data on age, gender, living arrangement, marital, education and prestroke employment status, and time after stroke were obtained through interview, while poststroke disability was evaluated with the modified Rankin Scale. Social support was assessed with the multidimensional scale of perceived social support (MSPSS). Univariate and multiple linear regression analyses were conducted. A P value of less than 0.05 is considered as significant. Univariate analysis showed that gender, education, and prestroke employment status were significantly associated with the availability of social support. In a regression model that accounted for 11 % of the variance in social support, prestroke employment was the only variable that independently influenced availability of social support (β = -0.33, P social network and was also found to influence significantly, the availability of poststroke social support in this study. Further studies are required to identify factors that more substantially influence the availability of social support after stroke.

  7. Functional Exercise and Physical Fitness Post Stroke: The Importance of Exercise Maintenance for Motor Control and Physical Fitness after Stroke

    Directory of Open Access Journals (Sweden)

    Birgitta Langhammer


    Full Text Available It is argued that all stroke patients, indifferent of disability, have the same possibility to improve with training. The aim of the study was to follow and register functional improvements in two groups with different functional capacities at baseline for a period of 36 months. Stroke patients were recruited and divided into groups related to their functional status at baseline. During the acute rehabilitation, both groups received functional task-oriented training, followed by regular self- or therapeutic driven training the first year after stroke and varied exercise patterns the following 24 months. The participants were tested on admission, and at three, six, twelve, and thirty-six months after the onset of stroke. Both groups improved functional activity up to six months which then stabilized up to twelve months to decline somewhat at thirty-six months after stroke. Change scores indicate a greater potential for rehabilitation in the MAS ≤35 in relation to group MAS >35 although the functional capacity was higher in the latter. This indicates the importance of maintaining exercise and training for all persons after stroke.

  9. Right hemispatial ipsilesional neglect with chronic right hemisphere strokes. (United States)

    Williamson, John B; Lamb, Damon G; Burtis, D Brandon; Haque, Salsabil; M Zilli, Eduardo; Kesayan, Tigran; Harciarek, Michal; Heilman, Kenneth M


    Patients who present with spatial neglect after stroke often perform normally on tests for neglect after a few weeks. Whereas tests for neglect are often performed directly in front of a patient, in their actual environments many important stimuli may be present within their left or right hemispace. The presence and severity of neglect often depends on the hemisphere injured. It is possible, in chronic stroke, for spatial judgments to be influenced by an interaction of stroke laterality and the spatial location of stimuli. The objective of this study was to learn if unilateral hemispheric chronic strokes contribute to a spatial bias with laterally presented stimuli. There were 70 participants, 62 with unilateral chronic strokes (>6 months post onset) including 35 with left hemisphere damage (LHD), 27 with right hemisphere damage (RHD), and 8 demographically similar people without history of stroke. Participants were asked to bisect 300 lines presented with distractors on the left, right, or both sides of the line, or no distractor, on a touch-screen monitor in right, center or left hemispace. There was a significant interaction between the side of the hemispheric lesion and the side of the body where these lines were presented. Specifically, in right space, patients with RHD deviated leftward in comparison to the other groups. Furthermore, there was an interaction between group and distractor induced bias. All three groups approached the left distractor, and the patients with LHD also approached the right distractor. Although spatial neglect is more severe in contralesional than ipsilesional hemispace in the period immediately following a stroke, over time patients with RHD may develop ipsilesional neglect that is more severe in ipsilesional than contralesional space. The mechanism underlying this bias is not known and may be related to attempted compensation or the development of a contralateral attentional/intentional grasp.

    Background and Purpose Visit-to-visit variability in BP is associated with ischemic stroke. We sought to determine whether such variability has a genetic aetiology and whether genetic variants associated with BP variability are also associated with ischemic stroke. Methods A GWAS for loci influencing BP variability was undertaken in 3,802 individuals from the Anglo-Scandinavian Cardiac Outcome Trial (ASCOT) study where long-term visit-to-visit and within visit BP measures were available. Since BP variability is strongly associated with ischemic stroke, we genotyped the sentinel SNP in an independent ischemic stroke population comprising of 8,624 cases and 12,722 controls and in 3,900 additional (Scandinavian) participants from the ASCOT study in order to replicate our findings. Results The ASCOT discovery GWAS identified a cluster of 17 correlated SNPs within the NLGN1 gene (3q26.31) associated with BP variability. The strongest association was with rs976683 (p=1.4×10−8). Conditional analysis on rs976683 provided no evidence of additional independent associations at the locus. Analysis of rs976683 in ischemic stroke patients found no association for overall stroke (OR 1.02; 95% CI 0.97-1.07; p=0.52) or its sub-types: CE (OR 1.07; 95% CI 0.97-1.16; p=0.17), LVD (OR 0.98; 95% 0.89-1.07; p=0.60) and SVD (OR 1.07; 95% CI 0.97-1.17; p=0.19). No evidence for association was found between rs976683 and BP variability in the additional (Scandinavian) ASCOT participants (p=0.18). Conclusions We identified a cluster of SNPs at the NLGN1 locus showing significant association with BP variability. Follow up analyses did not support an association with risk of ischemic stroke and its subtypes. PMID:23929743

  12. Barriers and facilitators to adherence to secondary stroke prevention medications after stroke: analysis of survivors and caregivers views from an online stroke forum. (United States)

    Jamison, James; Sutton, Stephen; Mant, Jonathan; De Simoni, Anna


    To identify barriers and facilitators of medication adherence in patients with stroke along with their caregivers. Qualitative thematic analysis of posts about secondary prevention medications, informed by Perceptions and Practicalities Approach. Posts written by the UK stroke survivors and their family members taking part in the online forum of the Stroke Association, between 2004 and 2011. 84 participants: 49 stroke survivors, 33 caregivers, 2 not stated, identified using the keywords 'taking medication', 'pills', 'size', 'side-effects', 'routine', 'blister' as well as secondary prevention medication terms. Perceptions reducing the motivation to adhere included dealing with medication side effects, questioning doctors' prescribing practices and negative publicity about medications, especially in regard to statins. Caregivers faced difficulties with ensuring medications were taken while respecting the patient's decisions not to take tablets. They struggled in their role as advocates of patient's needs with healthcare professionals. Not experiencing side effects, attributing importance to medications, positive personal experiences of taking tablets and obtaining modification of treatment to manage side effects were facilitators of adherence. Key practical barriers included difficulties with swallowing tablets, dealing with the burden of treatment and drug cost. Using medication storage devices, following routines and getting help with medications from caregivers were important facilitators of adherence. An online stroke forum is a novel and valuable resource to investigate use of secondary prevention medications. Analysis of this forum highlighted significant barriers and facilitators of medication adherence faced by stroke survivors and their caregivers. Addressing perceptual and practical barriers highlighted here can inform the development of future interventions aimed at improving adherence to secondary prevention medication after stroke. © Article author

  19. Management of Retained Genital Piercings: A Case Report and Review

    Directory of Open Access Journals (Sweden)

    Laura J. Moulton


    Full Text Available The prevalence of genital piercing among women is increasing. As the popularity increases, the number of complications from infection, injury, and retained jewelry is likely to rise. Techniques to remove embedded jewelry are not well described in the literature. The purpose of this report was to describe a case of a patient with a retained clitoral glans piercing, discuss a simple technique for outpatient removal, and review current evidence regarding associated risks of clitoral piercings. A 24-year-old female presented to the emergency department with an embedded clitoral glans piercing. Local anesthetic was injected into the periclitoral skin and a small superficial vertical incision was made to remove the ball of the retained barbell safely. In conclusion, among patients with retained genital piercing, outpatient removal of embedded jewelry is feasible. While the practice of female genital piercing is not regulated, piercing of the glans of the clitoris is associated with increased injury to the nerves and blood supply of the clitoris structures leading to future fibrosis and diminished function compared to piercing of the clitoral hood.
