High-Intensity Aphasia Intervention Is Minimally Fatiguing in Chronic Aphasia: An Analysis of Participant Self-Ratings From a Large Randomized Controlled Trial. Stroke 2024. [PMID: 38836352 DOI: 10.1161/strokeaha.123.046031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Accepted: 04/18/2024] [Indexed: 06/06/2024]
Abstract
BACKGROUND High-intensity therapy is recommended in current treatment guidelines for chronic poststroke aphasia. Yet, little is known about fatigue levels induced by treatment, which could interfere with rehabilitation outcomes. We analyzed fatigue experienced by people with chronic aphasia (>6 months) during high-dose interventions at 2 intensities. METHODS A retrospective observational analysis was conducted on self-rated fatigue levels of people with chronic aphasia (N=173) collected during a previously published large randomized controlled trial of 2 treatments: constraint-induced aphasia therapy plus and multi-modality aphasia therapy. Interventions were administered at a higher intensity (30 hours over 2 weeks) or lower intensity (30 hours over 5 weeks). Participants rated their fatigue on an 11-point scale before and after each day of therapy. Data were analyzed using Bayesian ordinal multilevel models. Specifically, we considered changes in self-rated participant fatigue across a therapy day and over the intervention period. RESULTS Data from 144 participants was analyzed. Participants were English speakers from Australia or New Zealand (mean age, 62 [range, 18-88] years) with 102 men and 42 women. Most had mild (n=115) or moderate (n=52) poststroke aphasia. Median ratings of the level of fatigue by people with aphasia were low (1 on a 0-10-point scale) at the beginning of the day. Ratings increased slightly (+1.0) each day after intervention, with marginally lower increases in the lower intensity schedule. There was no evidence of accumulating fatigue over the 2- or 5-week interventions. CONCLUSIONS Findings suggest that intensive intervention was not associated with large increases in fatigue for people with chronic aphasia enrolled in the COMPARE trial (Constraint-Induced or Multimodality Personalised Aphasia Rehabilitation). Fatigue did not change across the course of the intervention. This study provides evidence that intensive treatment was minimally fatiguing for stroke survivors with chronic aphasia, suggesting that fatigue is not a barrier to high-intensity treatment.

Abstract
BACKGROUND Vagus nerve stimulation (VNS) combined with rehabilitation is a Food and Drug Administration approved intervention for moderate to severe upper extremity deficits in chronic ischemic stroke patients. Previous studies demonstrated that VNS improves upper extremity motor impairments, using the Fugl Meyer Assessment of Upper Extremity (FMA-UE); however, delineating where these improvements occur, and the role of VNS dosage parameters were not reported. OBJECTIVE This study explored the relationship between dosing (time over which task repetitions were executed and number of VNS stimulations) and changes within proximal and distal components of the FMA-UE. METHODS Participants underwent VNS implantation, with 1 group receiving VNS paired with rehabilitation (Active VNS) and the other group receiving rehabilitation with sham stimulation (Controls). Both groups received 6 weeks of in-clinic therapy followed by a 90-day at-home, self-rehabilitation program. Participants who completed at least 12 of 18 in-clinic sessions were included in the analyses (n = l06). Pearson correlations and analysis of covariance were used to investigate the relationship between dosing and FMA-UE outcome change along with the effect of covariates including baseline severity, time since stroke, age, and paretic side. RESULTS Compared to Controls, active VNS favorably influenced distal function with sustained improvement after the home program. Significant improvements were observed in only distal components (FMdist) at both post day-1 (1.80 points, 95% Cl [0.85, 2.73], P < .001) and post-day 90 (1.62 points, 95% CI [0.45, 2.80], P < .007). CONCLUSIONS VNS paired with rehabilitation resulted in significant improvements in wrist and hand impairment compared to Controls, despite similar in-clinic dosing across both groups.NCT03131960.

Abstract
BACKGROUND Cardiovascular disease and stroke are common and costly, and their prevalence is rising. Forecasts on the prevalence of risk factors and clinical events are crucial. METHODS Using the 2015 to March 2020 National Health and Nutrition Examination Survey and 2015 to 2019 Medical Expenditure Panel Survey, we estimated trends in prevalence for cardiovascular risk factors based on adverse levels of Life's Essential 8 and clinical cardiovascular disease and stroke. We projected through 2050, overall and by age and race and ethnicity, accounting for changes in disease prevalence and demographics. RESULTS We estimate that among adults, prevalence of hypertension will increase from 51.2% in 2020 to 61.0% in 2050. Diabetes (16.3% to 26.8%) and obesity (43.1% to 60.6%) will increase, whereas hypercholesterolemia will decline (45.8% to 24.0%). The prevalences of poor diet, inadequate physical activity, and smoking are estimated to improve over time, whereas inadequate sleep will worsen. Prevalences of coronary disease (7.8% to 9.2%), heart failure (2.7% to 3.8%), stroke (3.9% to 6.4%), atrial fibrillation (1.7% to 2.4%), and total cardiovascular disease (11.3% to 15.0%) will rise. Clinical CVD will affect 45 million adults, and CVD including hypertension will affect more than 184 million adults by 2050 (>61%). Similar trends are projected in children. Most adverse trends are projected to be worse among people identifying as American Indian/Alaska Native or multiracial, Black, or Hispanic. CONCLUSIONS The prevalence of many cardiovascular risk factors and most established diseases will increase over the next 30 years. Clinical and public health interventions are needed to effectively manage, stem, and even reverse these adverse trends.

Abstract
BACKGROUND Quantifying the economic burden of cardiovascular disease and stroke over the coming decades may inform policy, health system, and community-level interventions for prevention and treatment. METHODS We used nationally representative health, economic, and demographic data to project health care costs attributable to key cardiovascular risk factors (hypertension, diabetes, hypercholesterolemia) and conditions (coronary heart disease, stroke, heart failure, atrial fibrillation) through 2050. The human capital approach was used to estimate productivity losses from morbidity and premature mortality due to cardiovascular conditions. RESULTS One in 3 US adults received care for a cardiovascular risk factor or condition in 2020. Annual inflation-adjusted (2022 US dollars) health care costs of cardiovascular risk factors are projected to triple between 2020 and 2050, from $400 billion to $1344 billion. For cardiovascular conditions, annual health care costs are projected to almost quadruple, from $393 billion to $1490 billion, and productivity losses are projected to increase by 54%, from $234 billion to $361 billion. Stroke is projected to account for the largest absolute increase in costs. Large relative increases among the Asian American population (497%) and Hispanic American population (489%) reflect the projected increases in the size of these populations. CONCLUSIONS The economic burden of cardiovascular risk factors and overt cardiovascular disease in the United States is projected to increase substantially in the coming decades. Development and deployment of cost-effective programs and policies to promote cardiovascular health are urgently needed to rein in costs and to equitably enhance population health.

Abstract
INTRODUCTION Propositional language and underlying executive functions can be impaired post-stroke and affect communication and quality of life. Current stroke screening tools are largely tailored to patients with aphasia, being either non-verbal or focussed on core language skills such as naming and repetition. The Brief Executive Language Screening Test (BELS) is a newly developed cognitive screening tool that assesses memory, oral apraxia, core language, as well as propositional language and associated executive functions that can be impacted and overlooked in stroke patients without aphasia. This study examines BELS sensitivity and specificity, and performance in acute to early sub-acute stroke relative to controls. METHOD Cross-sectional BELS data from 88 acute left and right hemisphere stroke patients (within 7 weeks of stroke) and 116 age-matched healthy controls were compared using independent samples t-tests. ROC Curve Analysis was performed to determine a cutoff score for the BELS. RESULTS Left and right stroke patients were reduced on all propositional language subtests, and executive function subtests of inhibition, strategy, and selection. Differences were also observed for Oral Apraxia, Naming, and Memory. By contrast, Word Comprehension and Repetition, and Sentence Completion Initiation (after corrections applied) did not differ between groups. A total BELS score of 79.25/100 was highly sensitive (.89) and specific (.89) when classifying stroke patients and healthy controls. CONCLUSION The BELS is brief, sensitive, suitable for bedside administration, and can aid in detection and rehabilitation of subtle executive language impairments. This in turn will help improve relationships and quality of life post-stroke.

Abstract
OBJECTIVE To analyze the effectiveness of acupoint stimulation combined with neurogenic bowel training on constipation in stroke patients. METHODS A retrospective analysis was conducted on the clinical data of 89 stroke patients with constipation admitted to our hospital from July 2022 to January 2024. All patients met the inclusion and exclusion criteria. The control group (n = 42) received neurogenic bowel training intervention, while the experimental group (n = 47) received finger acupoint stimulation combined with neurogenic bowel training intervention. Four outcome measures including intervention effects, bowel movements, Constipation Scoring System (CSS), and Scores on the Patient Assessment of Constipation Quality of Life (PAC-QOL) were compared between the two groups. RESULTS The total intervention effective rate in the experimental group (91.49%) was significantly higher than that in the control group (73.81%) (p < 0.05). Two weeks after intervention, the experimental group had significantly better first bowel movement time, average bowel movement time, and bowel movement interval time compared to the control group (p < 0.05). One and 2 weeks after intervention, the CSS and PAC-QOL scores in the experimental group were significantly better than those in the control group (p < 0.05). CONCLUSION Acupoint stimulation combined with neurogenic bowel training significantly improves constipation in stroke patients. Compared to neurogenic bowel training alone, the combined application of acupoint stimulation further improves bowel movements, reduces constipation severity, and enhances the quality of life in patients. Therefore, it is worthy of clinical promotion.

Abstract
BACKGROUND Atrial fibrillation (AF) often complicates ST elevation acute myocardial infarction (STEMI), with associated risks including stroke and mortality. Anticoagulation therapy for these patients and AF prognosis remains controversial. The aim was to evaluate long-term prognosis of STEMI patients complicated with AF in the acute phase. METHODS We performed a retrospective analysis on a prospective register involving 4,184 patients admitted for STEMI to the intensive cardiac care unit of 2 tertiary centres from 2007 to 2015. Patients with pre-existing permanent AF were excluded. Out of these, 269 (6.4%) patients developed AF within the first 48 hours after STEMI and were matched with a control group based on age and left ventricular ejection fraction (LVEF). RESULTS After matching, a total of 470 patients were included (n=235, AF-STEMI; n=235, control group). Mean age 69.0 years, and 31.7% women. No differences were found in gender, cardiovascular risk factors or ischemic heart disease. AF-STEMI patients experienced more sustained ventricular tachycardia, advanced atrioventricular block, heart failure, and cardiogenic shock. In-hospital mortality was also higher in AF-STEMI patients (11.9% vs 7.2%, p=0.008). After 10-years follow-up, the AF-STEMI group had remained with higher mortality (50.5% vs. 36.2%; p=0.003) and a greater recurrence of AF (44.2% vs. 14.7%; p<0.001), without differences in stroke incidence (10.1% vs. 9.3%). CONCLUSIONS As a conclusion, patients with AF complicating STEMI have higher rates of heart failure, cardiogenic shock, and in-hospital mortality. After a 10-year follow-up, they exhibit a high risk of AF recurrence and mortality, with no significant differences in stroke incidence.

Abstract
INTRODUCTION Distal medium vessel occlusion (DVO) thrombectomy has been shown to be efficacious with safety profiles comparable to large vessel occlusion (LVO) thrombectomy. A novel, highly-trackable, bevel-tipped Zoom 35 catheter can be used as an aspiration catheter for DVO thrombectomy. METHODS This is a retrospective, single-arm, multi-institutional observational study evaluating the efficacy and safety of aspiration thrombectomy for DVO using the Zoom 35 catheter. Patient demographics, presenting and discharge NIHSS, primary and rescue thrombectomy, site of occlusion, TICI score, and intracranial hemorrhage were chart abstracted. Descriptive statistics were used to evaluate the efficacy and safety of thrombectomy. RESULTS Fourteen patients (mean age 66.64 ± 13.75 years) were included. The mean NIHSS at presentation was 10.79 ± 5.48, and the mean ASPECTS was 9.00 ± 0.89. Nine patients (64.3%) received tPA. Primary occlusion location was M3 in nine cases (64.3%), M2/M3 junction in two cases (14.3%), A2 in one case (7.1%), A3 in one case (7.1%), and P1 in one case (7.1%). TICI scores were 3 in seven cases (50.0%), 2C in three cases (21.4%), and 2B in four cases (28.6%). There was one postoperative SAH (7.1%) and one asymptomatic ICH (7.1%). Mean discharge NIHSS was 3.38 ± 4.44, with a mean decrease of 7.31 from presentation (p < 0.0001, t-test). CONCLUSION Zoom 35 beveled-tip aspiration microcatheters are highly trackable and associated with improved radiographic and clinical outcomes for the treatment of DVO with a good safety profile.

Abstract
BACKGROUND Cardiovascular trials often use a composite end point and a time-to-first event model. We sought to compare edoxaban versus warfarin using the win ratio, which offers data complementary to time-to-first event analysis, emphasizing the most severe clinical events. METHODS ENGAGE AF-TIMI 48 (Effective Anticoagulation With Factor Xa Next Generation in Atrial Fibrillation-Thrombolysis in Myocardial Infarction 48) was a double-blind, randomized trial in which patients with atrial fibrillation were assigned 1:1:1 to a higher dose edoxaban regimen (60/30 mg daily), a lower dose edoxaban regimen (30/15 mg daily), or warfarin. In an exploratory analysis, we analyzed the trial outcomes using an unmatched win ratio approach. The win ratio for each edoxaban regimen was the total number of edoxaban wins divided by the number of warfarin wins for the following ranked clinical outcomes: 1: death; 2: hemorrhagic stroke; 3: ischemic stroke/systemic embolic event/epidural or subdural bleeding; 4: noncerebral International Society on Thrombosis and Haemostasis major bleeding; and 5: cardiovascular hospitalization. RESULTS 21 105 patients were randomized to higher dose edoxaban regimen (N=7035), lower dose edoxaban regimen (N=7034), or warfarin (N=7046), yielding >49 million pairs for each treatment comparison. The median age was 72 years, 38% were women, and 59% had prior vitamin K antagonist use. The win ratio was 1.11 (95% CI, 1.05-1.18) for higher dose edoxaban regimen versus warfarin and 1.11 (95% CI, 1.05-1.18) for lower dose edoxaban regimen versus warfarin. The favorable impacts of edoxaban on death (34% of wins) and cardiovascular hospitalization (41% of wins) were the major contributors to the win ratio. Results consistently favored edoxaban in subgroups based on creatine clearance and dose reduction at baseline, with heightened benefit among those without prior vitamin K antagonist use. CONCLUSIONS In a win ratio analysis of the ENGAGE AF-TIMI 48 trial, both dose regimens of edoxaban were superior to warfarin for the net clinical outcome incorporating ischemic and bleeding events. As the win ratio emphasizes the most severe clinical events, this analysis supports the superiority of edoxaban over warfarin in patients with atrial fibrillation.

Abstract
BACKGROUND A growing body of research examining the effect of exercise on cognitive function in stroke patients, while findings of available studies were conflicting. OBJECTIVES We aimed to estimate the effect of exercise on cognitive function in stroke patients. METHODS For this systematic review and meta-analysis, we searched PubMed, Web of Science, Embase, Cochrane, and Scopus electronic databases, through 13 March 2023. The three-level restricted maximum likelihood random effects model was used to synthesize the data. RESULTS Twenty-five studies met the inclusion criteria. There was a significant effect of exercise on improving cognitive function in stroke patients (Cohen's d = 0.37, 95% CI, 0.16 to 0.58, p < 0.01, I2 = 22.12%). Subgroup analysis showed that exercise significantly improved memory. In addition, aerobic exercise, exercise conducted 12 weeks or more, 3 times or more per week, less than 60 minutes per session, less than 180 minutes per week, and up to 12 months post-stroke increased cognitive function significantly. CONCLUSIONS Exercise improved cognitive function in stroke patients. To improve cognitive function, this meta-analysis provides clinicians with evidence to recommend that stroke patients participate in aerobic exercise at least 3 times per week for 30-60 minutes, with a goal of 180 minutes per week being achieved by increasing the frequency of exercise. Exercise initiated within 12 months post-stroke and continued for 12 weeks or more is most beneficial for improving cognitive function.

Abstract
We present a case of a single left hemisphere temporal-parietal stroke with subacute global aphasia and severe verbal apraxia and moderate dysphagia. The patient underwent a combined transcranial direct current stimulation (tDCS) over the left dorsolateral prefrontal cortex (DLPFC) and language stimulation with Virtual Reality Rehabilitation System (VRRS). Patient was treated in a 1-h session, for 5 days a week, for 4 consecutive weeks. After treatment, evident improvements in the comprehension of oral and written language, swallowing abilities, and caregiver burden were detected. Power spectrum analysis of EEG data revealed significant enhancements of θ, α, and β waves from baseline to follow-up. These preliminary results seem to confirm the reliability of the tDCS translational application in conjunction with computer-based cognitive treatment for language disorders in a patient with stroke-induced aphasia.

Abstract
BACKGROUND Atrial fibrillation (AF) is a major risk factor for ischaemic stroke (IS) and transient ischaemic attack (TIA). The timely detection of first-diagnosed or "new" AF (nAF) would prompt a switch from antiplatelets to anticoagulation to reduce the risk of stroke recurrence; however, the optimal timing and duration of rhythm monitoring to detect nAF remains unclear. AIMS We searched MEDLINE, PubMed, Cochrane database, and Google Scholar to undertake a systematic review and meta-analysis of randomized controlled trials (RCT) between 2012 and 2023 investigating nAF detection after IS and TIA. Outcome measures were overall detection of nAF (control; (usual care) compared to intervention; (continuous cardiac monitoring >72 h)) and the time period in which nAF detection is highest (0-14 days, 15-90 days, 91-180 days, or 181-365 days). A random-effects model with generic inverse variance weights was used to pool the most adjusted effect measure from each trial. SUMMARY OF REVIEW A total of eight RCTs investigated rhythm monitoring after IS, totaling 5820 patients. The meta-analysis of the studies suggested that continuous cardiac monitoring was associated with a pooled odds ratio of 3.81 (95% CI 2.14 to 6.77), compared to usual care (control), for nAF detection. In the time period analysis, the odds ratio for nAF detection at 0-14 days, 15-90 days, 91-180 days, 181-365 days were 1.79 (1.24-2.58); 2.01 (0.63-6.37); 0.98 (0.16-5.90); and 2.92 (1.30-6.56), respectively. CONCLUSION There is an almost fourfold increase in nAF detection with continuous cardiac monitoring, compared to usual care. The results also demonstrate two statistically significant time periods in nAF detection; at 0-14 days and 6-12 months following monitoring commencement. These data support the utilization of different monitoring methods to cover both time periods and a minimum of 1 year of monitoring to maximize nAF detection in patients after IS and TIA.

Abstract
Traumatic brain injuries (TBI) and stroke are major causes of morbidity and mortality in both developing and developed countries. The complex and heterogeneous pathophysiology of TBI and cerebral ischemia-reperfusion injury (CIRI), in addition to the blood-brain barrier (BBB) resistance, is a major barrier to the advancement of diagnostics and therapeutics. Clinical data showed that the severity of TBI and stroke is positively correlated with the number of neutrophils in peripheral blood and brain injury sites. Furthermore, neutrophil extracellular traps (NETs) released by neutrophils correlate with worse TBI and stroke outcomes by impairing revascularization and vascular remodeling. Therefore, targeting neutrophils to deliver NETs inhibitors to brain injury sites and reduce the formation of NETs can be an optimal strategy for TBI and stroke therapy. Herein, the study designs and synthesizes a reactive oxygen species (ROS)-responsive neutrophil-targeting delivery system loaded with peptidyl arginine deiminase 4 (PAD4) inhibitor, GSK484, to prevent the formation of NETs in brain injury sites, which significantly inhibited neuroinflammation and improved neurological deficits, and improved the survival rate of TBI and CIRI. This strategy may provide a groundwork for the development of targeted theranostics of TBI and stroke.

Abstract
AIM To describe patients' experiences of the quality of counselling to develop new digital counselling solutions for patients with cerebrovascular disease. DESIGN A descriptive, qualitative approach. METHODS Semi-structured in-person interviews were conducted among 22 patients diagnosed with acute cerebrovascular disease and treated as inpatients at a single university hospital in Finland between September 2021 and February 2022. Data were analysed using deductive and inductive content analysis. RESULTS The identified facilitators, barriers and possible solutions for the development of new digital counselling solutions were deductively categorized into five main categories: (1) background factors, (2) resources, (3) implementation, (4) sufficiency, and (5) effects and 12 generic categories. Patients with cerebrovascular diseases worry about symptoms affecting their ability to receive information and valued a supportive atmosphere. Staff should have more time for counselling and use motivational digital counselling solutions in plain language, moderate length and with multimedia content. Patients desired reminders, easy search functions and possibilities for two-way communication. CONCLUSION New digital counselling solutions could be beneficial in supporting the patients' knowledge, emotions and adherence. For the success of such solutions, patients' special needs concerning different levels of cognitive impairment need to be considered. IMPACT The results of this study may benefit healthcare organizations in the development of digital counselling solutions that meet the patients' needs. REPORTING METHOD We have adhered to relevant EQUATOR guidelines with the COREQ reporting method. PATIENT OR PUBLIC CONTRIBUTION Patients were involved as the study population.

Abstract
BACKGROUND Corticospinal tract (CST) is the principal motor pathway; we aim to explore the structural plasticity mechanism in CST during stroke rehabilitation. METHODS A total of 25 patients underwent diffusion tensor imaging before rehabilitation (T1), 1-month post-rehabilitation (T2), 2 months post-rehabilitation (T3), and 1-year post-discharge (T4). The CST was segmented, and fractional anisotropy (FA), axial diffusion (AD), mean diffusivity (MD), and radial diffusivity (RD) were determined using automated fiber quantification tractography. Baseline level of laterality index (LI) and motor function for correlation analysis. RESULTS The FA values of all segments in the ipsilesional CST (IL-CST) were lower compared with normal CST. Repeated measures analysis of variance showed time-related effects on FA, AD, and MD of the IL-CST, and there were similar dynamic trends in these 3 parameters. At T1, FA, AD, and MD values of the mid-upper segments of IL-CST (around the core lesions) were the lowest; at T2 and T3, values for the mid-lower segments were lower than those at T1, while the values for the mid-upper segments gradually increased; at T4, the values for almost entire IL-CST were higher than before. The highest LI was observed at T2, with a predominance in contralesional CST. The LIs for the FA and AD at T1 were positively correlated with the change rate of motor function. CONCLUSIONS IL-CST showed aggravation followed by improvement from around the lesion to the distal end. Balance of interhemispheric CST may be closely related to motor function, and LIs for FA and AD may have predictive value for mild-to-moderate stroke rehabilitation. Clinical Trial Registration.

Abstract
Aphasia is a communication disorder that affects processing of language at different levels (e.g., acoustic, phonological, semantic). Recording brain activity via Electroencephalography while people listen to a continuous story allows to analyze brain responses to acoustic and linguistic properties of speech. When the neural activity aligns with these speech properties, it is referred to as neural tracking. Even though measuring neural tracking of speech may present an interesting approach to studying aphasia in an ecologically valid way, it has not yet been investigated in individuals with stroke-induced aphasia. Here, we explored processing of acoustic and linguistic speech representations in individuals with aphasia in the chronic phase after stroke and age-matched healthy controls. We found decreased neural tracking of acoustic speech representations (envelope and envelope onsets) in individuals with aphasia. In addition, word surprisal displayed decreased amplitudes in individuals with aphasia around 195 ms over frontal electrodes, although this effect was not corrected for multiple comparisons. These results show that there is potential to capture language processing impairments in individuals with aphasia by measuring neural tracking of continuous speech. However, more research is needed to validate these results. Nonetheless, this exploratory study shows that neural tracking of naturalistic, continuous speech presents a powerful approach to studying aphasia.

Abstract
PURPOSE To explore quantitative and qualitative features of anomia in participants with left-hemisphere stroke, Parkinson's disease, or multiple sclerosis. MATERIALS AND METHODS This descriptive cross-sectional study compares signs of anomia within and across participants (n = 87), divided into four groups; moderate to severe anomia after stroke (MSAS, n = 19), mild anomia after stroke (MAS, n = 22), PD (n = 19) and MS (n = 27). Aspects analysed include naming accuracy and speed, the nature of incorrect responses, semantic and phonemic verbal fluency, information content in re-telling, and the relationship between test results and self-reports on word-finding difficulties and communicative participation. RESULTS All groups had impaired verbal fluency, prolonged response times and reduced information content in re-telling. The MSAS group had significantly more signs of anomia than the other groups. Results from the other groups overlapped on a MAS-PD-MS continuum. Both semantically and phonologically incorrect responses were common in the stroke groups, while semantically incorrect ones predominated in the PD and MS groups. All four groups reported a similar negative impact on self-perceived communicative participation. Correlations between self-reports and test results were inconsistent. CONCLUSIONS Anomia features have quantitative and qualitative similarities and differences across neurological conditions.

Abstract
BACKGROUND Comprehensive stroke centers (CSC) offer state-of-the-art stroke care in metropolitan centers. However, in rural areas, sufficient stroke expertise is much scarcer. Recently, telemedical stroke networks have offered instant consultation by stroke experts, enabling immediate administration of intravenous thrombolysis (IVT) on-site and decision on thrombectomy. While these immediate decisions are made during the consult, the impact of the network structures on stroke care in spoke hospitals is still not well described. AIMS This study was performed to determine if on-site performance in rural hospitals and patient outcome improve over time through participation and regular medical staff training within a telemedical stroke network. METHODS In this retrospective study, we analyzed data from stroke patients treated in four regional hospitals within the telemedical Neurovascular Network of Southwest Bavaria (NEVAS) between 2014 and 2019. We only included those patients that were treated in the regional hospitals until discharge at home or to neurorehabilitation. Functional outcome (modified Rankin scale) at discharge, mortality rate and periprocedural intracranial hemorrhage served as primary outcome parameters. Door-to-imaging and door-to-needle times were secondary outcome parameters. RESULTS In 2014-2019, 5,379 patients were treated for acute stroke with 477 receiving IVT. Most baseline characteristics were comparable over time. For all stroke patients, door-to-imaging times increased over the years, but significantly improved for potential IVT candidates and those finally treated with IVT. The percentage of patients with door-to-needle time <30 min increased from 10% to 25%. Clinical outcome at discharge improved for all stroke patients treated in the regional hospitals. Particularly for patients treated with IVT, good clinical outcome (modified Rankin scale 0-2) at discharge increased from 2014 to 2019 by 19% and mortality rates dropped from 13% to 5%. CONCLUSIONS 24-h/7-day telemedical support and regular on-site medical staff training within a structured telemedicine stroke network such as NEVAS significantly improve on-site stroke care in rural areas, leading to a considerable benefit in clinical outcome. DATA ACCESS STATEMENT The data that support the findings of this study are available upon reasonable request and in compliance with the local and international ethical guidelines.

Abstract
Objective: Stroke is the leading cause of disability worldwide. Traditionally, doctors assess stroke rehabilitation assessment, which can be subjective. Therefore, an objective assessment method is required. Methods: In this context, we investigated the changes in brain functional connectivity patterns and corticomuscular coupling in stroke patients during rehabilitation. In this study, electroencephalogram (EEG) and electromyogram (EMG) of stroke patients were collected synchronously at baseline(BL), two weeks after BL, and four weeks after BL. A brain functional network was established, and the corticomuscular coupling relationship was calculated using phase transfer entropy (PTE). Results: We found that during the rehabilitation of stroke patients, the overall connection of the brain functional network was strengthened, and the network characteristic value increased. The average corticomuscular PTE appeared to first decrease and subsequently increase, and the PTE increase in the frontal lobe was significant. Value: In this study, PTE was used for the first time to analyze the relationship between EEG signals in patients with hemiplegia. We believe that our findings contribute to evaluating the rehabilitation of stroke patients with hemiplegia.

Abstract
OBJECTIVE To evaluate the efficacy and safety of transcranial direct current stimulation in poststroke patients with upper extremity motor dysfunction using a systematic review and meta-analysis. DATA SOURCES We searched the Web of Science, Cochrane Library, EMBASE, and PubMed for randomized controlled trials investigating the effects of both active and sham stimulation up until January 27, 2024. REVIEW METHODS Efficacy, including the upper extremity Fugl-Meyer Assessment, Action Research Arm Test, Barthel Index, and safety, were assessed. The risk of bias was assessed using the Cochrane Risk of Bias 2 tool and the Physiotherapy Evidence Database Scale. Meta-analysis was performed using the RevMan 5.4 software. RESULTS Forty-four studies with 1555 participants were included. Transcranial direct current stimulation proved effective in improving upper extremity motor function (standardized mean difference = 0.22, 95% confidence interval: 0.12-0.32, P < 0.001) and Barthel Index (mean difference = 4.65, 95% confidence interval: 2.82-6.49, P < 0.001). Subgroup analysis revealed the highest transcranial direct current stimulation efficacy in patients with subacute stroke. Both anodal and cathodal stimulation were effective against upper extremity motor dysfunction. C3/C4 was the most effective stimulus target. Optimal stimulation parameters included stimulus current densities <0.057 mA/cm2 for 20-30 min and <30 sessions. Adverse effects and dropouts during follow-up showed that transcranial direct current stimulation is safe and feasible. CONCLUSIONS Our findings suggest that both anodal and cathodal stimulation were significantly effective in subacute stroke patients, particularly when preceding other treatments and when C3/C4 is targeted.
