Delirium is a common complication in acute stroke patients, occurring in 15–35% of all stroke unit admissions and is associated with prolonged hospital stay and a poor post-stroke prognosis. Managing delirium in acute stroke patients necessitates an intensive and multiprofessional therapeutic approach, placing a significant burden on healthcare staff. However, dedicated practical recommendations for delirium management developed for the population of acute stroke patients are lacking. For this purpose, the Austrian Stroke Society, in cooperation with the Austrian Society of Neurology, the Austrian Society of Neurorehabilitation, and the Austrian Society of Psychiatry, Psychotherapy, and Psychosomatics has formulated an evidence-based position paper addressing the management of delirium in acute stroke patients. The paper outlines practical recommendations on the three pillars of care in stroke patients with delirium: (a) Key aspects of delirium prevention including stroke-specific delirium risk factors and delirium prediction scores are described. Moreover, a non-pharmacological delirium prevention bundle is presented. (b) The paper provides recommendations on timing and frequency of delirium screening to ensure early diagnosis of delirium in acute stroke patients. Moreover, it reports on the use of different delirium screening tools in stroke populations. (c) An overview of non-pharmacological and pharmacological treatment strategies in patients with delirium and acute stroke is presented and summarized as key recommendation statements.

Introduction: Many guidelines now recommend early rehabilitation for acute stroke patients. However, evidence remains lacking regarding the specific timings for initiation of various rehabilitation steps and management when complications are encountered in acute stroke rehabilitation. This survey aimed to investigate actual clinical situations in acute stroke rehabilitation in Japan and to improve the medical systems for rehabilitation and plan further studies. Methods: This nationwide, cross-sectional, web-based questionnaire survey was administered between February 7, 2022, and April 21, 2022, targeting all primary stroke centers (PSCs) in Japan. Among several components of the survey, this paper focused on the timing of the initiation of three rehabilitation steps (passive bed exercise; head elevation; and out-of-bed mobilization), along with the management of rehabilitation (continued or suspended) in the event of complications during acute stroke rehabilitation. We also investigated the influence of facility features on these contents. Results: Responses were obtained from 639 of the 959 PSCs surveyed (response rate: 66.6%). In cases of ischemic stroke and intracerebral hemorrhage, most PSCs initiated passive bed exercise on day 1, head elevation on day 1, and out-of-bed mobilization on day 2 (with day of admission defined as day 1). In cases with subarachnoid hemorrhage, rehabilitation steps were delayed compared to other stroke subtypes or showed wide variation depending on the facility. Passive bed exercise was accelerated by the presence of protocols for rehabilitation and weekend rehabilitation. Out-of-bed mobilization was accelerated by the presence of a stroke care unit. Facilities with board-certified rehabilitation doctors were cautious regarding the initiation of head elevation. Most PSCs suspended rehabilitation training in the event of symptomatic systemic/neurological complications. Conclusion: Our survey revealed the actual situation of acute stroke rehabilitation in Japan and indicated that some facility features appear to influence early increases in physical activity levels and early mobilization. Our survey provides fundamental data to improve the medical systems for acute stroke rehabilitation in the future. [ABSTRACT FROM AUTHOR]

Introduction: Stroke is the second leading underlying cause of death globally and the leading cause of disability in adults. Stroke diagnosis should be performed quickly and efficiently to eliminate other potential causes of neurological deficits and to assess the time since the onset of clinical symptoms. Computed tomography (CT) and magnetic resonance imaging (MRI) are essential methods of detecting and evaluating stroke type and treatment options. Diffusion and perfusion MR imaging is recommended for early stroke diagnosis, as well as for the selection of patients for recanalization therapy, and is considered effective in assessing treatment outcomes. The objectives of this study were to demonstrate the diagnostic value of diffusion and perfusion imaging in the diagnosis of acute ischemic stroke, analyze the role of magnetic resonance imaging in the selection of patients with acute stroke for recanalization therapy, and assess the effect of acute stroke complicity. Material and methods: The research is designed as a systematic review of the primary scientific research literature, which was published in English in relevant scientific databases (PubMed, Google Scholar, Medline) from 2014 to 2021. Results: 14 scientific research papers were singled out and the general characteristics of the study were analyzed (country, authors, year of publication, title of the study, type of study, study objectives, research methods, results and conclusion). A quality assessment of the included studies with cohort design and randomized controlled studies was performed, and most belong to the category of high-quality studies with a smaller number of medium-quality studies. The overall percentage of detected AIS cases in isolated studies using the DWI and/or PWI sequence was 90.8%. At the same time, the outcome of recanalization therapy was assessed using MRI studies (the number of patients who developed adverse events with functional data outcome 30 or 90 days after the procedure was observed). Comparison of MRI and CT imaging protocols provided data on the total percentage of detected acute stroke cases using CT imaging protocols (68.9%) and MRI imaging protocols (88.5%), which is why MRI is considered a superior method. Conclusion: Although CT is a suitable method for visualizing bleeding and also for early differentiation of hemorrhagic from ischemic stroke, if MRI imaging is available, it is recommended to use DWI, PWI, MRA sequences for a more accurate diagnosis of stroke in the acute phase.

Imaging the bio-impedance distribution of the brain can provide initial diagnosis of acute stroke. This paper presents a compact and non-radiative tomographic modality, i.e. multi-frequency Electromagnetic Tomography (mfEMT), for the initial diagnosis of acute stroke. The mfEMT system consists of 12 channels of gradiometer coils with adjustable sensitivity and excitation frequency. To solve the image reconstruction problem of mfEMT, we propose an enhanced Frequency-Constrained Sparse Bayesian Learning (FC-SBL) to simultaneously reconstruct the conductivity distribution at all frequencies. Based on the Multiple Measurement Vector (MMV) model in the Sparse Bayesian Learning (SBL) framework, FC-SBL can recover the underlying distribution pattern of conductivity among multiple images by exploiting the frequency constraint information. A realistic 3D head model was established to simulate stroke detection scenarios, showing the capability of mfEMT to penetrate the highly resistive skull and improved image quality with FC-SBL. Both simulations and experiments showed that the proposed FC-SBL method is robust to noisy data for image reconstruction problems of mfEMT compared to the single measurement vector model, which is promising to detect acute strokes in the brain region with enhanced spatial resolution and in a baseline-free manner.

Objective: Acute stroke treatments reduce the likelihood of post-stroke disability, but are vastly underutilized. In this paper, we describe the development, adaptation, and scale-up of the Stroke Ready program - a health behavior theory-based stroke preparedness intervention that addresses underlying behavioral factors that contribute to acute stroke treatment underutilization. Methods: Through a community-based participatory research (CBPR) approach, we conducted needs and determinant assessments, which informed creation and pilot testing of Stroke Ready. Based on these results, we then scaled Stroke Ready to the entire community by greatly expanding the delivery system. Results: The scaled Stroke Ready program is a community-wide stroke preparedness education program consisting of peer-led workshops, print materials, and digital, social, and broadcast media campaigns. Whereas the Stroke Ready pilot workshop was delivered to 101 participants, 5945 participants have received the scaled Stroke Ready peer-led workshop to date. Additionally, we have sent mailers to over 44,000 households and reached approximately 35,000 people through our social media campaign. Conclusion: Strategies including an expanded community advisory board, adaptation of the intervention and communityengaged recruitment facilitated the scale-up of Stroke Ready, which may serve as a model to increase acute stroke treatment rates, particularly in majority African-American communities.

Acute stroke (the first hours after its onset) is accompanied in over 70% of cases by rapid and significant increases in blood pressure, above normal values. The acute or reactive hypertensive response occurs both in patients with a history of hypertension and in normotensive patients. The greatly increased BP values, not controlled therapeutically, can befollowed by the increase in the volume of the cerebral infarct and hemorrhagic transformation or thee xpansion of the hematoma and the increase in intracerebral pressure, respectively in ischemic or hemorrhagic stroke. This paper especially refers to the therapeutic control of hypertension in various situations (conditions): 1. Laboratory emergencies; 2. Hospital treatment with out thrombolytics or thrombolysis; 3. Endovascular treatment in acute stroke; 4. BP control in hemorrhagic stroke; 5. Continuation or discontinuation of antihypertensive treatement. The updated recommendations for the treatment of HTN in acute stroke result from clinical studies and recommendations of the recent ESO and AHA/ASA Guidelines. [ABSTRACT FROM AUTHOR]

Decision-making among older patients with stroke, their families and professionals has been extensively studied in a Western context, but there has been little prior work in China. The study reported here explored how decision-making took place between older people with stroke, their family carers and professionals in an acute care context in mainland China using a constructivist grounded theory approach. Data were collected through semi-structured interviews, participant observation and documentary analysis. Constant comparative analysis of the data was carried out. This paper focuses on the key social process of ‘hiding’ and its dynamic relationship with the core category ‘keeping the peace’. In order to meet the traditional Chinese cultural value of ‘maintaining harmony’, both family carers and professionals hid essential information from older stroke survivors who, as a consequence, were effectively precluded from playing an active role in major decisions. In understanding ‘hiding’, the paper draws upon both Chinese cultural values and ‘awareness context theory’ and in so doing questions the relevance to the Chinese context of key Western notions such as involvement in health-care decision-making. A better understanding of the experiences of decision-making processes between older people with stroke, their family carers and professionals in China will help professionals to provide the best possible support and care whilst promoting informed decision-making amongst all concerned.

Background: Mechanical thrombectomy (MT) has become the mainstay of treatment for acute ischemic stroke (AIS) recently. This case-control study aimed to identify the pivotal role of inflammation in the prognosis of AIS patients after MT. Methods: Altogether, 70 AIS patients who underwent MT were retrospectively recruited for this study. Receiver operating characteristic analysis was performed to demonstrate the sensitivity and specificity of the inflammatory variables for predicting prognosis. A meta-analysis was performed to pool the published results together. Stata software was used for analysis. Results: There was no differences in pre-MT inflammatory biomarkers between patients who survived and those who died, as well as patients with modified Rankin Scale (mRS) 0–2 and mRS ≥ 3. In contrast, post-MT C-reactive protein (CRP) levels might be a potential parameter to predict death after thrombectomy [area under the curve (AUC), 95%confidence interval (CI), 0.737, 0.587–0.887; p = 0.005; optimal cutoff value = 4.565]. Moreover, post-MT monocyte count might be an appropriate parameter to predict poor long-term prognosis after thrombectomy (AUC, 95%CI, 0.704, 0.575–0.833; p = 0.017; optimal cutoff value = 0.345). A meta-analysis revealed that the pre-MT inflammatory indices, including white blood cell count (weighted mean difference, 95%CI, 1.32, 1.01—1.63), neutrophil count (1.23, 0.95—1.51), monocyte count (0.05, 0.02—0.09), neuthrophil-to-lymphocyte ratio (2.42, 1.98—2.87) and platelet-to-lymphocyte ratio (24.65, 7.99—41.32), were higher in patients with 3-month mRS ≥ 3, and the lymphocyte count (−0.31,−0.43 to −0.18) was lower in this cohort. Conclusions: Inflammatory indices were significantly associated with the prognosis of patients undergoing MT, especially post-MT CRP and monocyte count, which can predict long-term outcomes.

An estimated 15 million people worldwide suffer a stroke each year, and in developed countries, survival is increasing. Of those who survive 30 days or more after their first event, many experience stroke-related vision and visual problems. Although screening for such problems after diagnosis of stroke is recommended, no standard method for complying with this recommendation is available. As visual problems are not always recognised by the sufferer, or obvious to others, they can be overlooked. Undetected problems result in distress to the individual and the people important to them, and may result in longer stays in hospital or repeat admissions. Health professionals in the acute care setting need to be aware that there is a risk of visual problems after stroke and have access to best practice guidance for screening, assessment and management of stroke-related visual problems. This paper describes the process used by a multidisciplinary team to develop a best practice statement for screening, assessment and management of vision problems during the acute phase of stroke.

Background To assist small hospitals in providing advanced stroke treatment, the Norwegian Directorate of Health has recommended telemedicine services. Telestroke enables specialists to examine patients via videoconferencing supplemented by teleradiology and to provide decision support to local health care personnel. There is evidence that telestroke increases thrombolysis rates. In Norway, telemedicine has mainly been used in non-critical situations. The first telestroke trials took place in 2008. The aim of this paper is to present an overview of telestroke trials and today's status with telestroke in Norway. Based on the divergent experience from two health regions in Norway, the paper discusses crucial factors for the integration of telestroke in clinical practice. Methods This is a descriptive study based on multiple methods to obtain an overview of the practice and experience with telestroke in Norway. A Web and literature search for 'telestroke in Norway' was performed and compared with a survey of telemedicine services at the country's largest hospitals. These findings were supplemented by interviews with key personnel involved in telestroke in two of four health regions, as well as hospital field observations and log data of telestroke transmissions from five of the hospitals involved. Results In Norway, experience in telemedicine for acute stroke care is limited. At the beginning of 2014, three of four regional health authorities were working with telestroke projects and services. Integration of the service in practice is challenging, with varying experience. The problems are not attributed to the technology in itself, but to organization (availability of staff on duty 24/7 and surveillance of the systems), motivation of staff, logistics (patient delay), and characteristics of the buildings (lack of space). Conclusions Prerequisites for successful integration of telestroke in clinical practice include realization of the collaboration potential in the technology with consistent procedures for training and triage, availability of the equipment, and providing advice beyond questions concerning thrombolysis.

Background: The PRE-hospital Stroke Treatment Organization was formed in 2016 as an international consortium of medical practitioners involved in pre-hospital treatment of patients with acute stroke. Aims: PRE-hospital Stroke Treatment Organization's mission is to improve stroke outcomes by supporting research and advocacy for pre-hospital stroke treatment in Mobile Stroke Units. PRE-hospital Stroke Treatment Organization will provide a platform to enhance collaborative research across the spectrum of acute stroke management in the prehospital setting. PRE-hospital Stroke Treatment Organization will also facilitate the appropriate proliferation and distribution of Mobile Stroke Units by providing a forum for professional communication, resource for public education, and stimulus for government, industry, and philanthropic support. Summary of review: In this "white paper", we describe the evidence supporting pre-hospital stroke treatment, progress to date, practical issues such as application in various environments and staffing, planned research initiatives, and organizational structure. Conclusions: PRE-hospital Stroke Treatment Organization is not-for-profit, with membership open to anyone involved (or hoping to become involved) in pre-hospital stroke care. PRE-hospital Stroke Treatment Organization has a Steering Committee comprised of members from Europe, U.S., Canada, Australia, and other regions having a Mobile Stroke Unit in operation. PRE-hospital Stroke Treatment Organization convenes satellite meetings for membership at the International Stroke Conference and European Stroke Congress each year to address the PRE-hospital Stroke Treatment Organization mission. The first research collaborations agreed upon are to: (1) develop a list of common data elements to be collected by all Mobile Stroke Unit programs and entered into a common research database, and (2) develop a protocol for investigating the natural history of hyper-acute Intracerebral Hemorrhage.

Purpose: In the treatment of intracranial arterial stenosis (ICAS), controversies remain regarding the optimal treatment strategy. Our study aims to conduct an individual patient-level data meta-analysis of existing RCTs comparing PTAS versus best medical therapy and to identify differences in outcomes such as incidence of ischemic stroke or death. Methods: Randomised controlled trials comparing the outcomes of stenting versus best medical therapy for patients who had symptomatic ICAS of >50%. Excluded studies included case reports, case series, reviews, observational studies, letters or studies evaluating isolated angioplasty techniques without stenting. Data was extracted in accordance with PRISMA guidelines. Results: 7 studies involving 1425 participants were included. There was an increased risk in the incidence of stroke and death within the first 30 days post-procedure for patients treated with PTAS over best medical therapy (RR = 2.22 [1.28–3.86], I² = 0%). Patients who underwent stenting also had a significantly higher risk of intracranial haemorrhage (RR = 12.66 [2.41–66.45], I² = 0%) and death (RR = 5.41 [1.20–24.28], I² = 0%). Under the shared frailty model, stenting when compared to medical therapy has a HR of 1.81 (95% CI:1.25–2.6) of stroke or death across 1 year. Under the parametric Royston-Parmar model, stenting has a significant decrease in the RMST(–0.83 months; 95% CI: –1.30–0.37). Stenting continued to show worse outcomes up to the 3 year mark with a HR of 1.60 (95% CI: 1.11–2.32). Conclusions and Relevance: There is an increased risk of peri- and post-procedural stroke and death over best medical therapy in patients with symptomatic ICAS who undergo PTAS. Further work is required to refine patient selection and mitigate peri-procedural risks. [ABSTRACT FROM AUTHOR]

Objective: This study aims to develop and validate the Futile Recanalization Prediction Score (FRPS), a novel tool designed to predict the severity risk of FR and aid in pre- and post-EVT risk assessments. Methods: The FRPS was developed using a rigorous process involving the selection of predictor variables based on clinical relevance and potential impact. Initial equations were derived from previous meta-analyses and refined using various statistical techniques. We employed machine learning algorithms, specifically random forest regression, to capture nonlinear relationships and enhance model performance. Cross-validation with five folds was used to assess generalizability and model fit. Results: The final FRPS model included variables such as age, sex, atrial fibrillation (AF), hypertension (HTN), diabetes mellitus (DM), hyperlipidemia, cognitive impairment, pre-stroke modified Rankin Scale (mRS), systolic blood pressure (SBP), onset-to-puncture time, sICH, and NIHSS score. The random forest model achieved a mean R-squared value of approximately 0.992. Severity ranges for FRPS scores were defined as mild (FRPS < 66), moderate (FRPS 66–80), and severe (FRPS > 80). Conclusions: The FRPS provides valuable insights for treatment planning and patient management by predicting the severity risk of FR. This tool may improve the identification of candidates most likely to benefit from EVT and enhance prognostic accuracy post-EVT. Further clinical validation in diverse settings is warranted to assess its effectiveness and reliability. [ABSTRACT FROM AUTHOR]

Stroke management employs a variety of diagnostic imaging modalities, image processing and analysis methods, and treatment procedures. This work categorizes methods for stroke imaging, image processing and analysis, and treatment, and provides their taxonomies illustrated by a state-of-the-art review. Imaging plays a critical role in stroke management, and the most frequently employed modalities are computed tomography (CT) and magnetic resonance (MR). CT includes unenhanced non-contrast CT as the first-line diagnosis, CT angiography, and CT perfusion. MR is the most complete method to examine stroke patients. MR angiography is useful to evaluate the severity of artery stenosis, vascular occlusion, and collateral flow. Diffusion-weighted imaging is the gold standard for evaluating ischemia. MR perfusion-weighted imaging assesses the penumbra. The stroke image processing methods are divided into non-atlas/template-based and atlas/template-based. The non-atlas/template-based methods are subdivided into intensity and contrast transformations, local segmentation-related, anatomy-guided, global density-guided, and artificial intelligence/deep learning-based. The atlas/template-based methods are subdivided into intensity templates and atlases with three atlas types: anatomy atlases, vascular atlases, and lesion-derived atlases. The treatment procedures for arterial and venous strokes include intravenous and intraarterial thrombolysis and mechanical thrombectomy. This work captures the state-of-the-art in stroke management summarized in the form of comprehensive and straightforward taxonomy diagrams. All three introduced taxonomies in diagnostic imaging, image processing and analysis, and treatment are widely illustrated and compared against other state-of-the-art classifications.

The management of blood pressure variability (BPV) in acute stroke presents a complex challenge with profound implications for patient outcomes. This narrative review examines the role of BPV across various stages of acute stroke care, highlighting its impact on treatment strategies and prognostic considerations. In the prehospital setting, while guidelines lack specific recommendations for BP management, emerging evidence suggests a potential link between BPV and outcomes. Among ischaemic stroke patients who are ineligible for reperfusion therapies, BPV independently influences functional outcomes, emphasising the need for individualised approaches to BP control. During intravenous thrombolysis and endovascular therapy, the intricate interplay between BP levels, recanalisation status, and BPV is evident. Striking a balance between aggressive BP lowering and avoiding hypoperfusion-related complications is essential. Intracerebral haemorrhage management is further complicated by BPV, which emerges as a predictor of mortality and disability, necessitating nuanced BP management strategies. Finally, among patients with acute subarachnoid haemorrhage, increased BPV may be correlated with a rebleeding risk and worse outcomes, emphasizing the need for BPV monitoring in this population. Integration of BPV assessment into clinical practice and research protocols is crucial for refining treatment strategies that are tailored to individual patient needs. Future studies should explore novel interventions targeting BPV modulation to optimise stroke care outcomes. [ABSTRACT FROM AUTHOR]

Gaps exist in the knowledge of return-to-driving guidelines, and education is needed for Australian health professionals working in the field of stroke. In this paper, authors evaluate the implementation of an e-learning module. A pre- and post-module knowledge test and survey were used to assess the e-module's success in achieving its learning objectives. Initially, 204 learners completed the module, with 68% of learners scoring 100% in the post-module knowledge test. Only 12 learners completed the survey. The authors recommend that health professionals other than occupational therapists access this e-module, and a review on e-module structure is required to improve results of knowledge tests.

Introduction. The Registry of Stroke Care Quality (RES-Q) is used in Poland for quality monitoring by numerous hospitals participating in the Angels Initiative. Our aim was to assess the degree of improvement in highly stroke-oriented centres that report cases to the RES-Q each year. Material and methods. This retrospective analysis included Polish stroke units that from January 2017 to December 2020 contributed to the RES-Q at least 25 patients annually. Results. Seventeen out of 180 Polish stroke units reported patients each year (2017, n = 1,691; 2018, n = 2,986; 2019, n = 3,750; 2020, n = 3,975). The percentage of ischaemic stroke patients treated with alteplase remained stable (26%, 29%, 30% and 28%, respectively). The door-to-needle time progressively decreased, from a median 49 minutes to 32 minutes. The percentage of patients treated = 60 minutes and = 45 minutes significantly increased (from 68% to 86% and from 43% to 70%, respectively), with no change observed between 2019 and 2020. Despite a general improvement in dysphagia screening (81%, 91%, 98% and 99%), screening performed within the first 24h from admission became less frequent (78%, 76%, 69% and 65%). In-hospital mortality significantly increased (11%, 11%, 13% and 15%), while the proportion of patients discharged home remained stable. Conclusions. Quality-oriented projects facilitate the improvement of stroke care, even in centres demonstrating good baseline performance. Polish stroke units that consistently reported cases to the RES-Q demonstrated improvement in terms of door-to--needle time and dysphagia screening. However, there is still a need to shorten the time to dysphagia screening, and carefully monitor stroke unit mortality following the COVID-19 pandemic. [ABSTRACT FROM AUTHOR]

OBJECTIVE: Endovascular treatment (EVT) has been demonstrated superior to pharmacological thrombolysis in acute ischemic stroke (AIS) induced by extracranial internal carotid artery occlusion. This paper aims to summarize clinical evidence about EVT and assess its efficacy and safety on acute extracranial carotid occlusion. MATERIALS AND METHODS: We systematically reviewed all studies that reported endovascular therapy as carotid stenting, stent retriever, aspiration, and angioplasty for acute extracranial carotid occlusion. Literature retrieval was performed in PubMed, Embase, and Cochrane library, dated from January 1st, 2005 to December 31st, 2020. The primary endpoint was a favorable outcome rate. Major secondary endpoints were SICH incidence, 90-day mortality rate, and complications. Meta-analysis and subgroup analysis were conducted to identify predictors for prognosis. This systematic review has been registered in PROSPERO (CRD42020181154) on July 18, 2020. RESULTS: 10 studies with 620 patients were included in total. Endovascular approach presented a favorable outcome rate of 0.47 (0.37, 0.56), an acceptable 90-day mortality rate of 0.16 (0.13, 0.19), and a mild SICH rate of 0.07 (0.05, 0.10). Age and NIHSS at admission were negatively associated with favorable outcome, with odds ratio of 0.95 (0.92, 0.98) and 0.74 (0.62, 0.88) respectively. Lower age (p=0.049) and aspiration thrombectomy (p=0.041) predicted less SICH events. In subgroup in which time window > 6 hours, endovascular therapy presented similar encouraging results, with favorable outcome rate of 0.59 (0.51, 0.66), 90-day mortality rate of 0.11 (0.07, 0.17), and SICH rate of 0.04 (0.02, 0.09). CONCLUSIONS: EVT can effectively improve neurological function and reduce 90-day mortality for acute extracranial carotid occlusion patients without increasing the risk of symptomatic intracranial hemorrhage. Endovascular therapy is safe to perform from 6 to 24 hours after symptom onset. [ABSTRACT FROM AUTHOR]

Purpose: Red blood cell distribution width (RDW) evaluates the variation (size heterogeneity) in red blood cells. Elevated RDW has been identified as a predictor of poor functional outcomes for acute ischemic stroke. The association between elevated RDW level and poor functional outcome in stroke patients undergoing mechanical thrombectomy has not been reported before. This study aims to investigate this relationship. Materials and Methods: This was a multicenter retrospective study involving the prospectively and consecutively collected data of 205 adult stroke patients who underwent mechanical thrombectomy for anterior circulation large vessel occlusion (middle cerebral artery M1, anterior cerebral artery A1, tandem ICA-MCA, carotid T) between July 2017 and December 2019. RDW cut off levels were accepted as >16%. The effect of elevated RDW on poor functional outcome (modified Rankin scale 3-6) was investigated using bivariate and multivariate regression analysis. Results: Elevated RDW was significantly associated with poor functional outcome in bivariate and multivariate analysis (odds ratio [OR] for RDW >16%, 2.078; 95% confidence interval [95% CI], 1.083-3.966; P=0.027 and OR for RDW >16%, 2.873; 95% CI, 1.342-6.151; P=0.007; respectively). Conclusion: These findings suggest that elevated RDW may be an independent predictor of poor functional outcomes in ischemic stroke patients undergoing mechanical thrombectomy.

Background: There is increasing evidence for music-based interventions in neurorehabilitation, improving mood and functional outcomes. In response, there is growing interest from health-care providers in setting up Neurologic Music Therapy (NMT) services. This paper presents some preliminary data on the feasibility and acceptability of NMT in the acute stroke, multidisciplinary team setting, about which little is known. Objectives: To assess the feasibility and acceptability of a two-day per-week NMT service over 24 months. Methods: Data were collected on the number of referrals received, sessions attended, sessions declined and reasons why. Staff completed questionnaires, and collected them from patients and their relatives, rating interventions: 1. Not helpful, 2. Quite helpful, 3. Helpful, 4. Very helpful. Patients completed the Visual Analogue Mood Scale (VAMS) pre-/post- a single session. Results: Of 201 patients referred, 177 received treatment and 675 sessions were delivered. Twenty-four patients were discharged before sessions were scheduled and 28 sessions were declined, predominantly due to fatigue. Mean scores (SD) from questionnaire data were: patients (n = 99) 3.34 (0.825), relatives (n = 13) 3.83 (0.372), staff (n = 27) 3.85 (0.388). Mean, post-session VAMS data (n = 52) showed a non-significant reduction in 'Sad' (7.5, p =.007, CI = 2.1, 12.9) and an increase in 'Happy' (+ 6.2, p =.013, CI = −11.0, −1.4). Conclusions: Data suggest the service was feasible and helpful, particularly for patient mood, possibly improving engagement in rehabilitation. Research to determine generalizability in different stroke environments and treatment effects within them is warranted. [ABSTRACT FROM AUTHOR]
