Upplevelser av livskvalitet efter stroke och faktorer som associeras med livskvalitet : En litteraturstudieGrip, Victoria, Johansson, Madeleine January 2010 (has links)
<p>Syftet med studien var att beskriva hur personer som har drabbats av stroke upplever sin livskvalitet samt vilka faktorer som associeras med livskvalitet. Designen var en beskrivande litteraturstudie och litteratur söktes i databaserna Medline (via PubMed) och Cinahl. Efter urvalet återstod 15 artiklar som inkluderades i studien. Artiklarna granskades och fyra huvudkategorier kunde utrönas: livskvalitet efter stroke, fysiska, psykiska och sociala faktorer som associeras med livskvalitet. Resultatet visade att personer som har drabbats av stroke ofta uppvisar sänkt livskvalitet. Fysiska faktorer av betydelse var försämrade kroppsfunktioner och kognitiv nedsättning. Äldre personer och kvinnor skattade ofta sin livskvalitet lägre jämfört med yngre och män. Den viktigaste psykiska faktorn var depression. En social faktor av betydelse för sänkt livskvalitet var minskat socialt deltagande. Slutsatsen med studien var att kunskap kring hur personer som har drabbats av stroke upplever sin livskvalitet och vilka faktorer som associeras med livskvalitet kan ge vägledning för vilken typ av stöd och rehabilitering som behövs.</p> / <p>The purpose of the study was to describe how persons who have had a stroke experience their quality of life and which factors are associated with quality of life. The design was a descriptive literature study and literature was sought in the databases Medline (via PubMed) and Cinahl. After the selection a sample of 15 articles was included in the study. The articles were reviewed and four main categories were found: quality of life post stroke, physical, psychological or social factors associated with quality of life. The result showed that persons who had a stroke often show decreased quality of life. Physical factors of importance were impaired body functions and decreased cognitive function. Older persons and women often measured their quality of life as lower compared to younger persons and men. The most important psychological factor was depression. A social factor of importance related to reduced quality of life was decreased social participation. The conclusion of the study was that knowledge about how persons who had a stroke experience their quality of life and which factors are associated with quality of life could give guidance for what kind of support and rehabilitation is needed. </p>

Aspects on stroke outcome : survival, functional status, depression and sex differences in Riks-Stroke, the National Quality Register for Stroke CareEriksson, Marie January 2008 (has links)
Stroke is a major cause of death and disability worldwide. In Sweden, about 30 000 strokes occur each year. The aim of this thesis was to analyse survival, functional outcome and self-reported depression after stroke, and to explore possible differences between men and women in stroke care and outcome. These studies were based on Riks-Stroke, the Swedish national quality register for stroke care. Information on background variables and treatment were collected during the hospital stay. The patient’s situation and outcome after stroke were followed-up after 3 months. Long term survival was retrieved from the Swedish Population Register (Folkbokföringen). Possible sex-differences in stroke care and outcome 3 months after stroke were explored in 24 633 strokes, registered during 2006. In conscious patients, the proportions treated at stroke units were similar for men and women. Men and women had equal chance to receive thrombolytic therapy or secondary prevention with oral anticoagulants. Compared to men, women were less likely to develop pneumonia, but more likely to experience deep venous thromboses and fractures during hospital stay. Women had worse 3-month survival and functional outcome, differences that were explained by their higher age and impaired level of consciousness on admission. Women felt more depressed and perceived their health as worse than men did. Women were also less satisfied with the care they had received in the hospital. The agreement between self-reported functional outcome 3 months after stroke and the commonly used modified Rankin Scale (mRS) was explored in 555 stroke survivors from 4 hospitals during May-September 2005. Riks-Stroke’s self-reported questions classified 76% of the patients into correct mRS grade. The association between functional outcome 3 months after stroke and 3-year survival was assessed in 15 959 men and women who had had a stroke during 2001-2002. Patients with estimated mRS grades 3, 4 and 5 had hazard ratios for death of 1.7, 2.5 and 3.8, respectively, as compared with patients with lower grades, 0-2. Depressed mood, male sex, high age, diabetes, smoking, antihypertensive therapy at onset and atrial fibrillation were also identified as predictors of poor survival. Self-reported depression 3 months after stroke and use of antidepressants were analysed in 15 747 stroke survivors from 2002. Fourteen percent felt depressed 3 months after stroke. Female sex, age <65, previous stroke, living alone or in institution, or being dependent in activities of daily living (ADL) were factors associated with self-reported depression. At the follow-up, 22% of the men and 28% of the women were using antidepressant medication, which were approximately twice as many as in the general population. Still, 8% of all patients in Riks-Stroke reported depressive mood but no treatment with antidepressants. In conclusion, men and women with stroke in Sweden experience similar treatment and outcome in most aspects. Patient-reported functional outcome can be reliably transformed to a standard disability scale. Impaired functional outcome three months after stroke is an independent predictor of poor long-term survival. Depressive mood is common after stroke and is associated with poor survival and impaired functional outcome.

INVESTIGATION OF GENETIC FACTORS DETERMINING ISCHEMIC STROKE OUTCOMECHU, PEI-LUN January 2013 (has links)
<p>Cerebrovascular disease (stroke), especially ischemic stroke, is a major cause of death and neurological disability in adults. Because of its clinical heterogeneity, stroke is considered as a multi-factorial and polygenic disorder. Most current genetic studies of ischemic stroke focus on genetic susceptibility rather than factors determining stroke outcome. The genetic components of ischemic stroke outcome are difficult to study in humans due to environmental factors and medical intervention. Thus, we proposed to use a surgically induced, permanent, focal cerebral ischemic stroke mouse model to investigate genetic factors of ischemic stroke outcome measured by infarct volume. This model is the middle cerebral artery occlusion (MCAO) model. First, we screened infarct volumes across 32 inbred mouse strains. The infarct volume varies between strains, and this strongly suggests that infarct volume is genetically determined. To identify these genetic factors, we used genome-wide association study [Efficient Mixed-Model Association (EMMA) analysis] on infarct volume from 32 inbred mouse strains. Using the EMMA analysis, we identified 11 infarct volume-associated loci; however, most loci were mapped with missing alleles. This suggests that these loci might be false positives. Thus, we used specifically designed scripts of EMMA analysis with updated mouse SNP database to correct for potential false positives. The loci identified by the updated EMMA analyses will led us to the identification of genes involved in ischemic stroke outcome. </p><p> There are two major mechanisms were proposed to be determinants of infarct volume, the extent of native collateral circulation and neuroprotection. Using the infarct volume screening panel from 32 inbred strains, we observed that infarct volume is inversely correlated with the native collateral vessel number. However, among these inbred strains, we also observed several strains differ significantly in infarct volumes but harbor similar collateral numbers. In order to identify genetic factors determining infarct volume in a collateral-independent manner (neuroprotection), we used quantitative trait locus (QTL) mapping on mouse strains that exhibit the most difference in infarct volumes but the least difference in collateral numbers (C57BL/6J and C3H/HeJ). From the F2 B6 x C3H cross, we mapped 4 loci determining infarct volume (cerebral infarct volume QTL 4 to 7, Civq4 to Civq7). The Civq4 locus is the strongest locus (LOD 9.8) that contributes 21% of phenotypic variance in infarct volume. We also used a parallel F2 B6 x C3H cross to perform a QTL mapping on collateral vessel traits to further verify these collateral-independent loci. Among these 4 loci, the Civq4 and Civq7 loci appear to be truly collateral-independent. Based on strain-specific sequence variants and mRNA expression differences, we proposed Msr1 and Mtmr7 are the potential candidate genes of the Civq4 locus. Identification of the collateral-independent genetic factors will help to understand the genetic architecture, disease pathophysiology and potential therapeutic targets for of ischemic stroke</p> / Dissertation

Crises epilépticas e epilepsia após acidente vascular cerebral isquêmico com uso de terapia de reperfusão (rt-PA) ou hemicraniectomia descompressivaBrondani, Rosane January 2015 (has links)
Base teórica: O Acidente Vascular Cerebral (AVC) é a causa mais comum de novos diagnósticos de epilepsia no idoso. Embora a epilepsia pós-AVC seja um fenômeno clínico reconhecido há muito tempo, seguem muitas questões não resolvidas. Além disso, nas últimas duas décadas, o tratamento do AVC isquêmico sofreu mudanças radicais com a introdução da trombólise e da hemicraniectomia descompressiva (HD) para o tratamento do infarto maligno de artéria cerebral média (ACM). As consequências destas duas novas abordagens terapêuticas nas características da epilepsia pós-AVC ainda são pouco exploradas. Objetivo: Estudar as características e estimar fatores de risco para as crises epilépticas ou a epilepsia pós-AVC em pacientes submetidos ao tratamento agudo (Estudo 1) ou HD para infarto maligno de ACM (Estudo 2). Métodos: O estudo 1 é uma coorte de 153 pacientes submetidos a trombólise. Variáveis estudadas incluiram fatores de risco para o AVC e variáveis associadas ao AVC isquêmico agudo e trombólise. Utilizamos a análise de regressão de Cox para o estudo das variáveis que se associaram de forma independente com crises epilépticas, epilepsia pós-AVC e o desfecho do AVC. O estudo 2 é também uma coorte que retrospectivamente avaliou 36 pacientes com infarto maligno de ACM tratados com HD. Tempo, incidência e fatores de risco para crises epilépticas e desenvolvimento de epilepsia foram analisados. Resultados: Estudo 1: 74 pacientes (48,4%) eram mulheres; média de idade foi 67,2 anos (DP=13,1). Média do NIHSS na chegada foi 10,95 (DP=6,25) e 2,09 (DP=3,55) após 3 meses. Transformação hemorrágica ocorreu em 22 (14,4%) dos pacientes. Foi considerado desfecho bom classificação na escala modificada de Rankin (mRS) 0-1, sendo encontrado em 87 (56,9%) dos pacientes. Vinte e um pacientes (13,7%) tiveram crises epilépticas e 15 (9,8%) desenvolveram epilepsia após a trombólise. Crises epilépticas foram associadas de forma independente com transformação hemorrágica e desfecho não favorável (mRS ≥ 2) em três meses após o AVC. Transformação hemorrágica e mRS ≥ 2 avaliados em 3 meses, associaram-se de forma independente com epilepsia pós-AVC. Crises epilépticas surgiram como um fator de risco independente para desfecho pobre. Estudo 2. A média de seguimento dos pacientes foi de 1.086 (DP= 1.172) dias. Nove pacientes morreram antes de receberem alta hospitalar e no período de um ano, 11 pacientes haviam morrido. Quase 60% alcançaram mRS ≤ 4. Treze pacientes desenvolveram crises dentro da primeira semana após o AVC. No total, crises epilépticas ocorreram em 22 (61%) dos 36 pacientes. Dezenove pacientes (56%) dos 34, sobreviveram ao período agudo e desenvolveram epilepsia após infarto da ACM e HD. Questionamos aos pacientes ou responsáveis se eles se arrependeram de terem autorizado a HD no momento do AVC. Também foi perguntado se eles autorizariam a HD novamente. Trinta e dois (89%) não se arrependeram de ter autorizado a HD no momento do infarto agudo da ACM, e autorizaria novamente em retrospecto. Conclusão: Confirmamos que as frequências de crises ou epilepsia pós-AVC e trombolítico são comparáveis com as frequências das décadas da era pré-trombólise e confirmamos a alta incidência de crises epilépticas e epilepsia após infartos malignos de ACM submetidos a HD. Em nosso estudo, as crises epilépticas associaram-se de forma independente com pior prognóstico após terapia trombolítica. / Background: The most common cause of newly diagnosed epilepsies in the elderly is stroke. Although post-stroke epilepsy is a well-studied stroke complication, many questions remain unsolved. In addition, during the past two decades, the treatment of stroke has changed dramatically with the introduction of thrombolysis for treatment of acute ischemic stroke (AIS) and decompressive hemicraniectomy (DHC) for malignant middle cerebral artery infarction (MCA). The consequences of these two new therapeutic approaches for characteristics of post-stroke epilepsy remains poorly explored. Objective: To study characteristics and estimate risk factors for acute seizures or post-stroke epilepsy in patients submitted to thrombolysis for treatment of acute stroke (Study 1) or DHC for malignant MCA infarction. Methods: Study 1 is a cohort study of 153 patients submitted to thrombolysis. Variables studied included risk factors for stroke, and variables related to acute stroke and thrombolysis. Variables independently associated with seizures, pos-stroke epilepsy or stroke outcome were defined using Cox regression analysis. Study 2 is also a cohort study that retrospectively assessed 36 patients with malignant stroke of the MCA submitted to DHC. Timing, incidence and plausible risk factors for seizure and epilepsy development were analyzed in these patients. Results: Study 1. Seventy-four patients (48.4%) were female; mean age of patients was 67.2 years-old (SD=13.1). Initial NIHSS mean score was 10.95 (SD=6.25) and 2.09 (SD=3.55) after three months. Hemorrhagic transformation occurred in 22 (14.4%) patients. A good outcome, as defined by a modified Rankin Scale (mRS) of 0-1, was observed in 87 (56.9%) patients. Twenty one (13.7%) patients had seizures and 15 (9.8%) patients developed epilepsy after thrombolysis. Seizures were independently associated with hemorrhagic transformation and with mRS ≥ 2 three months after stroke. Hemorrhagic transformation and unfavorable outcome, as measured by mRS ≥ 2 after three months, were variables independently associated with post-stroke epilepsy. Seizures emerged as an independent factor for poor outcome in stroke thrombolysis. Study 2. Mean patient follow-up time was of 1.086 (SD=1.172) days. Nine patients died before being discharged and after one year eleven patients died. Almost 60% had the modified Rankin score ≤ 4. Thirteen patients developed seizures within the first week after stroke. In total, seizures occurred in 22 (61%) of 36 patients. Nineteen patients (56%) out of 34 patients who survived the acute period developed epilepsy after MCA infarcts and DHC. Also, we asked patients or the person responsible for them whether they regretted, in retrospect, having authorized DHC at the time of the stroke. It was also asked whether they would authorize DHC again. Thirty- two (89%) did not regret having authorized DHC at the time of acute MCA infarct, and would authorize DHC again in retrospect. Conclusion: We confirm that seizures or post-stroke epilepsy rates after thrombolysis are comparable with rates from pre-thrombolysis decades and a high incidence of seizures and epilepsy after malignant MCA infarcts submitted to DHC. In our study, seizures were an independent risk factor associated with worst outcome after thrombolysis therapy.
