Blood pressure and LDL-cholesterol targets for prevention of recurrent strokes and cognitive decline in the hypertensive patient: design of the European Society of Hypertension-Chinese Hypertension League Stroke in Hypertension Optimal Treatment randomized trial.

BACKGROUND AND OBJECTIVES: The SBP values to be achieved by antihypertensive therapy in order to maximize reduction of cardiovascular outcomes are unknown; neither is it clear whether in patients with a previous cardiovascular event, the optimal values are lower than in the low-to-moderate risk hypertensive patients, or a more cautious blood pressure (BP) reduction should be obtained. Because of the uncertainty whether 'the lower the better' or the 'J-curve' hypothesis is correct, the European Society of Hypertension and the Chinese Hypertension League have promoted a randomized trial comparing antihypertensive treatment strategies aiming at three different SBP targets in hypertensive patients with a recent stroke or transient ischaemic attack. As the optimal level of low-density lipoprotein cholesterol (LDL-C) level is also unknown in these patients, LDL-C-lowering has been included in the design. PROTOCOL DESIGN: The European Society of Hypertension-Chinese Hypertension League Stroke in Hypertension Optimal Treatment trial is a prospective multinational, randomized trial with a 3 × 2 factorial design comparing: three different SBP targets (1, <145-135; 2, <135-125; 3, <125 mmHg); two different LDL-C targets (target A, 2.8-1.8; target B, <1.8 mmol/l). The trial is to be conducted on 7500 patients aged at least 65 years (2500 in Europe, 5000 in China) with hypertension and a stroke or transient ischaemic attack 1-6 months before randomization. Antihypertensive and statin treatments will be initiated or modified using suitable registered agents chosen by the investigators, in order to maintain patients within the randomized SBP and LDL-C windows. All patients will be followed up every 3 months for BP and every 6 months for LDL-C. Ambulatory BP will be measured yearly. OUTCOMES: Primary outcome is time to stroke (fatal and non-fatal). Important secondary outcomes are: time to first major cardiovascular event; cognitive decline (Montreal Cognitive Assessment) and dementia. All major outcomes will be adjudicated by committees blind to randomized allocation. A Data and Safety Monitoring Board has open access to data and can recommend trial interruption for safety. SAMPLE SIZE CALCULATION: It has been calculated that 925 patients would reach the primary outcome after a mean 4-year follow-up, and this should provide at least 80% power to detect a 25% stroke difference between SBP targets and a 20% difference between LDL-C targets.

International survey of acute stroke imaging used to make revascularization treatment decisions.

BACKGROUND: To assess the differences across continental regions in terms of stroke imaging obtained for making acute revascularization therapy decisions, and to identify obstacles to participating in randomized trials involving multimodal imaging. METHODS: STroke Imaging Repository (STIR) and Virtual International Stroke Trials Archive (VISTA)-Imaging circulated an online survey through its website, through the websites of national professional societies from multiple countries as well as through email distribution lists from STIR and the above mentioned societies. RESULTS: We received responses from 223 centers (2 from Africa, 38 from Asia, 10 from Australia, 101 from Europe, 4 from Middle East, 55 from North America, 13 from South America). In combination, the sites surveyed administered acute revascularization therapy to a total of 25,326 acute stroke patients in 2012. Seventy-three percent of these patients received intravenous (i.v.) tissue plasminogen activator (tPA), and 27%, endovascular therapy. Vascular imaging was routinely obtained in 79% (152/193) of sites for endovascular therapy decisions, and also as part of standard IV tPA treatment decisions at 46% (92/198) of sites. Modality, availability and use of acute vascular and perfusion imaging before revascularization varied substantially between geographical areas. The main obstacles to participate in randomized trials involving multimodal imaging included: mainly insufficient research support and staff (50%, 79/158) and infrequent use of multimodal imaging (27%, 43/158) . CONCLUSION: There were significant variations among sites and geographical areas in terms of stroke imaging work-up used tomake decisions both for intravenous and endovascular revascularization. Clinical trials using advanced imaging as a selection tool for acute revascularization therapy should address the need for additional resources and technical support, and take into consideration the lack of routine use of such techniques in trial planning.

Association between independence in daily activities and social roles in older adults with stroke

La réadaptation des personnes âgées ayant subi un accident vasculaire cérébral vise à améliorer les capacités et l’indépendance dans les activités de la vie courante. Les personnes âgées reprennent leurs rôles sociaux lorsqu’elles retournent vivre dans la communauté. L’objectif de ce mémoire est de clarifier la relation entre l’indépendance dans les activités de la vie courante au congé de la réadaptation intensive et la reprise des rôles sociaux six mois plus tard. L’échantillon se compose de 111 participants recrutés au congé et réévalués 6 mois plus tard. L’indépendance dans les activités de la vie courante est mesurée avec les sections pertinentes du Système de Mesure de l’Autonomie Fonctionnelle (SMAF). Les rôles sociaux sont mesurés avec la Mesure des Habitudes de Vie (MHAVIE); un score total ainsi que 4 sous-scores pour les responsabilités civiles, la vie communautaire, les relations interpersonnelles et les loisirs sont générés. Des analyses de régression hiérarchique sont utilisées pour vérifier l’association entre les activités de la vie courantes (variable indépendante) et les rôles sociaux (variables dépendante) tout en contrôlant pour les capacités (variables de contrôle). Les résultats suggèrent des associations significatives (p < .001) entre les activités de la vie courante et les rôles sociaux (score total de la MHAVIE), les sous scores des responsabilités civiles et de la vie communautaire, mais aucune association avec les relations interpersonnelles et les loisirs. Les scores les plus faibles sont obtenus pour les loisirs. Une deuxième phase de réadaptation après le retour à domicile pourrait permettre le développement des loisirs.

Role of corticospinal influences in post-stroke spasticity

Chez les personnes post-AVC (Accident Vasculaire Cérébral), spasticité, faiblesse et toute autre coactivation anormale proviennent de limitations dans la régulation de la gamme des seuils des réflexes d'étirement. Nous avons voulu savoir si les déficits dans les influences corticospinales résiduelles contribuaient à la limitation de la gamme des seuils et au développement de la spasticité chez les patients post-AVC. La stimulation magnétique transcranienne (SMT) a été appliquée à un site du cortex moteur où se trouvent les motoneurones agissant sur les fléchisseurs et extenseurs du coude. Des potentiels évoqués moteurs (PEM) ont été enregistrés en position de flexion et d'extension du coude. Afin d'exclure l'influence provenant de l'excitabilité motoneuronale sur l'évaluation des influences corticospinales, les PEM ont été suscités lors de la période silencieuse des signaux électromyographiques (EMG) correspondant à un bref raccourcissement musculaire juste avant l'enclenchement de la SMT. Chez les sujets contrôles, il y avait un patron réciproque d'influences corticospinales (PEM supérieurs en position d'extension dans les extenseurs et vice-versa pour les fléchisseurs). Quant à la plupart des sujets post-AVC ayant un niveau clinique élevé de spasticité, la facilitation corticospinale dans les motoneurones des fléchisseurs et extenseurs était supérieure en position de flexion (patron de co-facilitation). Les résultats démontrent que la spasticité est associée à des changements substantiels des influences corticospinales sur les motoneurones des fléchisseurs et des extenseurs du coude.

Brief neuropsychological assessment of adults post-stroke in the left hemisphere

The neuropsychological assessment investigates cognitive deficits to improve the diagnosis, the prognosis and the rehabilitation of patients. In Brazil, stroke is a major cause of hospitalization and the leading cause of mortality and disability. The stroke in the left hemisphere (LH) is associated with different degrees of loss of language and other cognitive impairments, for example, in the memory. We compared the performance in brief neuropsychological tasks of the left hemisphere poststroke patients, without moderate or severe aphasia, with healthy controls. A list of 135 patients was selected based on inclusion criteria. The study included 15 patients with left stroke, paired by sex, age and education to 30 neurologically healthy adults. The data resulting from application of the Neupsilin Brief Neuropsychological Assessment Instrument were analyzed with the nonparametric Mann-Whitney U. Adults with LH stroke showed a significant reduction in performance when compared to healthy controls on language, working memory and ideomotor praxis, results also found in other studies of patients with left hemisphere stroke
