Abstract
BACKGROUND Patients with minor stroke or transient ischemic attacks have an increased risk of future strokes. These patients are often discharged home with limited specialized follow-up, although close to half of them experience cognitive deficits. Simple encouragements to avoid smoking, be physically active, and to take preventive medication are often insufficient to ensure adherence and more comprehensive interventions are needed to support the patients in adapting healthy behaviour. The aim of this study was to test the feasibility and potential effect of an early initiated, patient-centred intervention to patients with minor stroke or transient ischemic attacks targeting smoking, physical activity, and medication adherence, in a randomized, controlled pilot trial. METHODS Hospitalized patients were randomized to usual care or an intervention consisting of health behavioural counselling based on the 5A's model, telephone follow-up (4 and 8 weeks), and monitoring of physical activity. Follow-up time was 12 weeks. Feasibility was on the following domains: eligibility, acceptance, demand and practicality, adherence, attrition, and implementation and integration. RESULTS Forty patients of 84 potentially eligible were randomized to the two treatment arms (20 intervention/20 usual care). Thirty-two completed the 12-week follow-up, while 8 were either excluded or lost to follow-up. With few changes, the intervention was feasible and possible to deliver according to the protocol. CONCLUSION It was possible to identify relevant patients who could potentially benefit from a behavioural intervention, recruit and randomize them early after admission and retain most participants in the study until follow-up and derive statistical estimates to guide the design of large-scale randomized controlled trials.

Abstract
Cerebral Stroke is an acute cerebrovascular disease, a disease of brain tissue damage caused by the sudden rupture or blockage of blood vessels in the brain that prevents blood flow to the brain. Acupuncture has become a popular treatment for stroke, with auricular acupuncture providing a new idea for stroke treatment. However, the neuromodulatory mechanism of auricular acupuncture in the brain is still unclear. The aim of this study was to investigate the effect of auricular acupuncture in the treatment of upper limb dysfunction and the activation of specific brain regions in stroke patients. Forty patients with stroke hemiplegia who met the nerf criteria were included in the experiment and randomly assigned into two groups (20 patients in each group): the auricular acupuncture group and the control group. Fugl-Meyer score (FMA) assessment of upper limb motor function, motor evoked potential (MEP) measurement, and functional near-infrared brain function imaging (fNIRS) data acquisition in the primary motor M1 area of the brain at rest were performed before and after treatment, respectively. It was found that: 1) after auricular acupuncture treatment, the patients in the auricular acupuncture group showed significantly greater peak MEP and significantly higher oxyhemoglobin content in the M1 region of the brain compared with the control group, with a significant activation effect (MEP: P-value = 0.032, t = -2.22; HbO2; f = 4.225, p = 0.046); 2) in the clinical efficacy assessment, the FMA score in the auricular acupuncture group after treatment (p = 0.0122, t = 2.769). The results suggest that auricular acupuncture has an ameliorative effect on upper limb motor deficits after stroke and that activation of the M1 region of the brain may be a key node in auricular acupuncture for treating upper limb dysfunction in stroke patients, a finding that emphasizes the potential for clinical application of auricular acupuncture therapy for stroke patients with potential mechanisms influencing the outcome.

Plasma growth differentiation factor - 8 / Myostatin level as prognostic biomarker of patients with ischemic stroke and acute revascularization therapy. PARADISE study. J Neurol Sci 2023; 448:120611.

Abstract
BACKGROUND Identifying biological markers of ischemic stroke (IS) is an important research approach to develop innovative therapeutic strategies. This study aimed to assess the association between plasma Growth Differentiation Factor-8 (GDF-8)/Myostatin levels and outcome of IS patients. METHODS Consecutive patients with acute IS treated with either intravenous thrombolysis and/or mechanical thrombectomy at Dijon University Hospital, France were prospectively included. Clinical variables were recorded, and plasma GDF-8 was collected just after the revascularization procedure. Primary endpoint was functional outcome at 3 months assessed by the modified Rankin Scale (mRS) score. Secondary endpoints included mRS scores at 6 and 12 months, and overall mortality over 1-year of follow-up. RESULTS Among the 173 included patients (median age: 76 years, Interquartile range (IQR): 66-85; 49% women), median plasma GDF-8 levels at admission were significantly lower in those with a poor outcome at 3 months defined as a mRS score > 2 (2073 (IQR: 1564-2757) pg/mL versus 1471 (1192-2241) pg/mL, p < 0.001). Lower GDF-8 levels at admission were associated with higher 3-months mRS score in multivariable ordinal logistic regression analysis (OR = 0.9995; 95% CI: 0.9991-0.9999, p = 0.011). The association was also observed with 6- and 12-month mRS scores. Although mortality was higher in patients with lower GDF-8 levels, the association was not significant in multivariable Cox analysis. CONCLUSION Lower plasma GDF-8 levels were associated with a poorer functional outcome in IS patients treated with acute revascularization therapy. Underlying pathophysiological mechanisms involving GDF-8 in post-stroke outcome remain to be elucidated.

Abstract
BACKGROUND AND PURPOSE Because stroke therapy has changed with the introduction of endovascular stroke treatment as a standard approach, studies on intrahospital causes of death from stroke are no longer up-to-date. The purpose of this observational study was to present the causes of death during hospitalization of patients with ischemic stroke who received endovascular stroke treatment, with the focus on a differentiation of curative and secondary palliative treatment. MATERIALS AND METHODS We studied a total cohort of 1342 patients who received endovascular stroke treatment in a tertiary stroke center (Aachen, Germany) between 2010 and 2020 and analyzed the causes of death in all 326 consecutive deceased patients. We distinguished between curative treatment and a secondary palliative approach and analyzed causes of death and treatment numbers across the years. RESULTS In the entire cohort of 326 deceased patients, the most common cause of death was of a cerebrovascular nature (51.5%), followed by pneumonia and sepsis (25.8%) and cardiovascular causes (8.3%). Neurovascular causes constituted 75.8% of reasons for palliation. In the group with a secondary palliative approach, causes of death were neurovascular in 54.0% of patients and pneumonia and sepsis in 26.0% of patients. CONCLUSIONS Cerebrovascular causes in patients with stroke play a major role in the intrahospital causes of death and reasons for palliation. Considering the large proportion of secondarily palliative-treated patients, reasons for palliation should be considered instead of causes of death to avoid concealment by, for example, life-terminating measures.

Lifestyle counselling as secondary prevention in patients with minor stroke and transient ischemic attack: study protocol for a randomized controlled pilot study. Pilot Feasibility Stud 2020; 6:40. [PMID: 32226634 PMCID: PMC7093950 DOI: 10.1186/s40814-020-00583-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2019] [Accepted: 03/11/2020] [Indexed: 01/10/2023] Open
Abstract
BACKGROUND Most patients with minor stroke or transient ischemic attack (TIA) are discharged with little or no specialised follow-up. Nonetheless, these patients have a high prevalence of cognitive impairments and a considerable risk of recurrent stroke. Smoking cessation, physical activity, and adherence to antihypertensive and antithrombotic medication are highly recommended in patients with minor stroke and TIA. Evidence suggests that simple encouragement to change lifestyle is ineffective. Behavioural interventions might therefore be needed to support patients in managing their own health post-discharge. OBJECTIVES We aim to test the (1) feasibility of randomisation acceptance and an early initiated, client-centred lifestyle and behavioural intervention in a clinical setting, and (2) potential effect of the intervention on arterial blood pressure in patients with minor stroke or TIA and (3) explore the participants experience of barriers and facilitators for health behaviour after a stroke, including perceived needs and social support. METHODS We will conduct a randomized controlled pilot trial: Eligible patients with acute minor stroke or TIA (n = 40) will be randomly allocated to either early initiated counselling with four weekly post-discharge follow-up sessions for 12 weeks or usual care. The primary outcome will be program feasibility and to discuss the relevance of arterial blood pressure as primary outcome after 12 weeks intervention. Selected participants will be invited to participate in semi-structured interviews, based on purposeful sampling, to evaluate the intervention and explore their experience of life after a stroke. The interviews will be analysed using a five-step thematic analysis approach. DISCUSSION The study will provide evidence of the feasibility and potential effect of early initiated counselling on cardiovascular risk factors in patients with minor stroke and TIA. Qualitative interviews will contribute with a more nuanced understanding of the barriers and facilitators of health enhancing behaviour. Optimizing health behaviour counselling and providing formal support to the patients' post-discharge may ease the transition and help more patients adhere to lifestyle and medication recommendations.

Abstract
OBJECTIVES Most studies show that marriage conveys a survival advantage. Whether this is valid also for stroke patients is unclear. Results of studies have been inconsistent and conflicting. MATERIAL & METHODS We studied 1-week and 1-month stroke case-fatality in relation to marital status (married, unmarried, divorced, and widowed) in all patients admitted to hospital for incident stroke in Denmark during 2003-2012. We used information from Danish registries on stroke merged to information on age, sex, marital status, stroke severity, stroke subtype, socioeconomic status, cardiovascular risk profile, and causes of death. We studied deaths due to the index stroke within the first week and month after stroke. Multivariate Cox regression models were applied to estimate cause-specific hazards and relative risks. RESULTS We included 60507 patients with an incident stroke of which 51.19% were married, 9.47% were unmarried, 13.29% were divorced, and 26.05% were widowers. Death within the first week and first month was caused by stroke in 2110 (3.5%) and 3423 (5.7%) patients, respectively. Compared to married stroke patients, 1-week/1-month case-fatality (by stroke) was lower for the unmarried (HR (hazard ratio):0.69/0.74), divorced (HR:0.69/0.72), and widowed (HR:0.80/0.74) men and the unmarried (HR:0.84/0.86), divorced (HR:0.82/0.80), and widowed (HR:0.87/0.88) women with stroke. CONCLUSIONS One-week and one-month case-fatality by stroke was lower among the unmarried, divorced, and widowed than among the married stroke patients. Selection by so-called mortality displacement linked to shorter life expectancy among divorced, widowed, and singles may explain our findings.

Abstract
BACKGROUND AND PURPOSE Most stroke rehabilitation studies have been performed in high-income countries. The aim of this study was to identify the main barriers for patient inclusion in a research protocol performed in Brazil. METHODS We evaluated reasons for exclusion of patients in a pilot, randomized, double-blinded clinical trial of stroke rehabilitation. Descriptive statistical analysis was performed. RESULTS Only 5.6% of 571 screened patients were included. Recurrent stroke was responsible for exclusion of 45.4% of potentially eligible patients. CONCLUSIONS Recurrent stroke represented a big barrier to enroll patients in the protocol. External validity of rehabilitation trials will benefit from definition of study criteria according to regional characteristics of patients, including rates of recurrent stroke.

Abstract
Background and Purpose The aims of this study were to determine the 28-day and 1-year survival rates after first-ever ischemic stroke and to identify their baseline predictors. Methods We prospectively and consecutively collected data on 300 patients with first-ever acute ischemic stroke admitted to 2 major neurological institutions for cerebrovascular diseases in Belgrade during March 2008. The Kaplan-Meier method was used to estimate the cumulative 28-day and 1-year survival rates, and the predictive values of different variables were assessed by Cox proportional-hazards regression model. Results The cumulative 28-day and 1-year survival rates of ischemic stroke patients in the cohort were 81.0% and 78.3%, respectively. The multivariate predictive model revealed that hypertension (p=0.017), National Institutes of Health Stroke Scale score (p=0.001), and in-hospital medical complications (p=0.029) were significant unfavorable independent outcome predictors, while early physical therapy (p=0.001) was a significant favorable prognostic factor for the 28-day mortality in our patients. Multivariate Cox regression analysis showed that age (p=0.001), National Institutes of Health Stroke Scale score (p=0.001), and in-hospital complications (p=0.008) remained significant predictors of 1-year mortality. Conclusions The findings support the need for optimal control of vascular risk factors and treatment of atherosclerotic disease as well as appropriate prevention and management of in-hospital complications of stroke.

Abstract
We investigated cause-specific mortality in relation to age, sex, stroke severity, and cardiovascular risk factor profile in the Copenhagen Stroke Study cohort with 10 years of follow-up. In a Copenhagen community, all patients admitted to the hospital with stroke during 1992-1993 (n = 988) were registered on admission. Evaluation included stroke severity, computed tomography scan, and a cardiovascular risk profile. Cause of death within 10 years according to death certificate information was classified as stroke, heart/arterial disease, or nonvascular disease. Competing-risks analyses were performed by cause-specific Cox regression after multiple imputation of missing data, assuming that values were missing at random. Death was due to stroke in 310 patients (31%), to heart/arterial disease in 209 patients (21%), and to nonvascular diseases in 289 patients (29%); 180 patients were still alive after 10 years (18%). Stroke was the dominant cause of death during first year, with an absolute risk of 20.2% versus 5.2% for heart/arterial disease and 6.5% for nonvascular disease. The subsequent absolute risk of death per year was 2.8% for stroke, 4.5% for heart/arterial disease, and 5.2% for nonvascular disease. Death after stroke was associated with older age, male sex, greater stroke severity, and diabetes regardless of the cause of death. Previous stroke and hemorrhagic stroke were associated with death by stroke, ischemic heart disease was associated with death by heart/arterial disease and atrial fibrillation was associated with death by cardiovascular disease (stroke or heart/arterial disease). Hypertension, smoking, and alcohol consumption were not associated with cause-specific death.

Abstract
BACKGROUND AND PURPOSE Predictors of early case-fatality (3-day, 7-day, and 30-day) in first-ever ischemic stroke were identified and compared with predictors of late case-fatality (90-day and 1-year). METHODS A registry designed to register hospitalized patients with stroke in Denmark 2000 to 2007 holds 26,818 patients with first-ever ischemic stroke with information on stroke severity (Scandinavian Stroke Scale), CT scan, cardiovascular risk factors, marital status, and fatality within 1 year. Multiple logistic regression was used in identifying predictors. RESULTS Mean age was 71.2 years; 48.5% were women; mean Scandinavian Stroke Scale score was 43.9. Early case-fatality showed stroke severity and age were significant predictors of 3-day, 7-day, and 30-day case-fatality (nonlinear effect). In addition, atrial fibrillation (OR, 1.56) predicted 30-day case-fatality. For late case-fatality, significant predictors of 90-day and 1-year case-fatality were age, stroke severity (nonlinear effect), atrial fibrillation (OR, 1.37 and 1.57), and diabetes (OR, 1.35 and 1.33), respectively. Male gender (OR, 1.28), previous myocardial infarction (OR, 1.40), and smoking (OR, 1.21) were also associated with 1-year case-fatality. Alcohol consumption, hypertension, intermittent arterial claudication, and marital state had no influence. All case-fatality rates accelerated with increasing age, but 3-day and 7-day case-fatality rates tended to level off or decline at the highest ages. CONCLUSIONS Age and stroke severity were the only significant predictors of fatality within the first poststroke week; they were associated with late case-fatality as well. Cardiovascular risk factors were associated with late case-fatality; with the exception of atrial fibrillation, they were not significantly associated with early case-fatality rates.
