Background: Few studies explore the patient heterogeneity, trajectory development, and factors influencing the functional recovery of the postacute care cerebrovascular disease (PAC-CVD) program. The objective of the study was to analyze the group-based trajectory and different functional improvement for patients with acute stroke participating in the PAC-CVD program. Materials and Methods: A total of 328 patients with acute stroke who had participated in PAC-CVD program in rehabilitation departments of three hospitals from 2014 to 2017 were enrolled in this retrospective cohort study. Latent profile analysis (LPA) was applied to analyze the clinical characteristics between high- and low-function groups (LFGs). The analysis of variance and Chi-square test were used to analyze the association between functional grouping and patients' characteristics. Results: In the study baseline, patients could be divided into high function group (HFG; 85/328 = 25.9%), medium function group (MFG; 128/328 = 39.02%), and (LFG; 115/328 = 35.06%) by LPA. age (P = 0.001), length of hospital stays (P = 0.001), male sex (P = 0.048), and lesion type (P = 0.023) were significantly associated with being grouped in the high-function group. After 6 weeks of rehabilitation training, 100% of HFG remained as HFG, 49.04% of MFG transitioned to HFG, and 50% of MFG continued to remain as MFG. 8.41% of LFG transitioned to HFG, 57% of LFG transitioned to MFG, but still, 34.58% of LFG continued to remain as LFG. Conclusion: Identifying initial functional groups can guide medical professionals to target patients for PAC service use. PAC-CVD high-intensity rehabilitation significantly enhances acute stroke patients' functional recovery, though effectiveness varies over time. These factors highlight the need for further development of rehabilitation programs to boost patient independence. [ABSTRACT FROM AUTHOR]

Ischemic stroke, caused by the interruption of the blood supply to the brain, requires prompt medical intervention to prevent irreversible damage. Anesthetic management is pivotal during surgical treatments like mechanical thrombectomy, where precise strategies ensure patient safety and procedural success. This narrative review highlights key aspects of anesthetic management in ischemic stroke, focusing on preoperative evaluation, anesthetic choices, and intraoperative care. A rapid yet thorough preoperative assessment is crucial, prioritizing essential diagnostic tests and cardiovascular evaluations to determine patient frailty and potential complications. The decision between general anesthesia (GA) and conscious sedation (CS) remains debated, with GA offering better procedural conditions and CS enabling continuous neurological assessment. The selection of anesthetic agents—such as propofol, sevoflurane, midazolam, fentanyl, remifentanil, and dexmedetomidine—depends on local protocols and expertise balancing neuroprotection, hemodynamic stability, and rapid postoperative recovery. Effective blood pressure management, tailored airway strategies, and vigilant postoperative monitoring are essential to optimize outcomes. This review underscores the importance of coordinated care, incorporating multimodal monitoring and maintaining neuroprotection throughout the perioperative period. [ABSTRACT FROM AUTHOR]

Background: We performed an analysis of a large intensive care unit electronic database to provide preliminary estimates of various blood pressure parameters in patients with acute stroke receiving intravenous (IV) antihypertensive medication and determine the relationship with in-hospital outcomes. Methods: We identified the relationship between pre-treatment and post-treatment systolic blood pressure (SBP) and heart rate (HR)–related variables and in-hospital mortality and acute kidney injury in patients with acute stroke receiving IV clevidipine, nicardipine, or nitroprusside using data provided in the Medical Information Mart for Intensive Care (MIMIC) IV database. Results: A total of 1830 patients were treated with IV clevidipine (n = 64), nicardipine (n = 1623), or nitroprusside (n = 143). The standard deviations [SDs] of pre-treatment SBP (16.3 vs. 13.7, p ≤ 0.001) and post-treatment SBP (15.4 vs. 14.4, p = 0.004) were higher in patients who died compared with those who survived, particularly in patients with intracerebral hemorrhage (ICH). The mean SBP was significantly lower post treatment compared with pre-treatment values for clevidipine (130.7 mm Hg vs. 142.5 mm Hg, p = 0.006), nicardipine (132.8 mm Hg vs. 141.6 mm Hg, p ≤ 0.001), and nitroprusside (126.2 mm Hg vs. 139.6 mm Hg, p ≤ 0.001). There were no differences in mean SDs post treatment compared with pre–treatment values for clevidipine (14.5 vs. 13.5, p = 0.407), nicardipine (14.2 vs. 14.6, p = 0.142), and nitroprusside (14.8 vs. 14.8, p = 0.997). The SDs of pre-treatment and post-treatment SBP were not significantly different in patients with ischemic stroke treated with IV clevidipine, nicardipine, or nitroprusside or for patients with ICH treated with IV clevidipine or nitroprusside. However, patients with ICH treated with IV nicardipine had a significantly higher SD of post-treatment SBP (13.1 vs. 14.2, p = 0.0032). Conclusions: We found that SBP fluctuations were associated with in-hospital mortality in patients with acute stroke. IV antihypertensive medication reduced SBP but did not reduce SBP fluctuations in this observational study. Our results highlight the need for optimizing therapeutic interventions to reduce SBP fluctuations in patients with acute stroke. [ABSTRACT FROM AUTHOR]

Introduction: Sleep Disordered Breathing (SDB) has been shown to increase the risk of stroke and despite recommendations, routine evaluation for SDB in acute stroke is not consistent across institutions. The necessary logistics and expertise required to conduct sleep studies in hospitalized patients remain a significant barrier. This study aims to evaluate the feasibility of high-resolution pulse-oximetry (HRPO) for the screening of SDB in acute stroke. Secondarily, considering impact of SDB on acute stroke, we investigated whether SDB at acute stroke predicts functional outcome at discharge and at 3 months post-stroke. Methods: Patients with acute mild to moderate ischemic stroke underwent an overnight HRPO within 48 h of admission. Patients were divided into SDB and no-SDB groups based on oxygen desaturations index(ODI > 10/h). Stepwise multivariate logistic regression analysis was applied to identify the relevant predictors of functional outcome (favorable [mRS 1–2 points] versus unfavorable [mrS > = 3 points]). Results: Of the 142 consecutively screened patients, 96 were included in the analysis. Of these, 33/96 (34%) were identified as having SDB and were more likely to have unfavorable mRS scores as compared to those without SDB (odds ratio = 2.70, p-value = 0.032). Conclusion: HRPO may be a low-cost and easily administered screening method to detect SDB among patients hospitalized for acute ischemic stroke. Patients with SDB (as defined by ODI) have a higher burden of neurological deficits as compared to those without SDB during hospitalization. [ABSTRACT FROM AUTHOR]

This study aimed to determine whether the distance of gait training using a hybrid assistive limb (HAL) is related to the improvement of walking independence in patients with acute brain injury. This was an exploratory, observational study. Thirty patients having hemiplegia (functional ambulation category, FAC score ≤2) with acute stroke or after brain tumor surgery were included. Patients performed 4 sessions of gait training using HAL (60 min/session), 1–3 sessions/week, combined with conventional physical therapy. The gait distance achieved in the four training sessions using HAL was measured. FAC score was measured before and after intervention. Patients were divided into groups A, B, and C, for FAC score improvements of 0, 1, and ≥2, respectively. Gait distance was compared among groups using one-way analysis of variance. Gait distance in group C was significantly longer than that ingroup A [mean (standard deviation): 2527 (1725) m vs. 608 (542) m]. This study suggested that the gait distance achieved during training using the HAL may be a clinical indicator of the effectiveness of the HAL on gait training in patients with acute brain injury. Clinical trial registration number: UMIN000012764 R000014756. [ABSTRACT FROM AUTHOR]

(1) Background: Acute ischemic stroke treatment has been thoroughly studied to identify strategies to reduce treatment times. However, many centers still struggle to achieve fast treatment times. Additionally, studies primarily focus on larger, more advanced centers; yet, smaller centers often face longer treatment times. (2) Objectives: The aim of this study is to analyze the existing literature reviewing stroke treatment processes in primary and comprehensive stroke centers that investigated or reduced treatment times. The articles identified were categorized based on the focus areas and approaches used. (3) Results: Three main categories of improvements were identified in the literature: (1) standardization of processes, (2) resource management, and (3) data collection. Both primary and comprehensive stroke centers were able to reduce treatment times through standardization of the processes. However, challenges such as variations in hospital resources and difficulties incorporating data collection software into workflow were highlighted. Additionally, many strategies to optimize resources and data collection that can benefit primary stroke centers were only conducted in comprehensive stroke centers. (4) Conclusions: Many existing strategies to improve stroke treatment times, such as pre-notification and mass stroke team alerts, have been implemented in both primary and comprehensive stroke centers. However, tools such as simulation training are understudied in primary stroke centers and should be analyzed. Additionally, while data collection and feedback are recognized as crucial for process improvement, challenges persist in integrating consistent data collection methods into clinical workflow. Further development of easy-to-use software tailored to clinician needs can help improve stroke center capabilities to provide feedback and improve treatment processes. [ABSTRACT FROM AUTHOR]

Introduction: Hospital overcrowding where patient admissions exceed capacity is associated with worse outcomes in Emergency Department. Developments in emergency stroke care have been associated with improvements in stroke outcome but are dependent on effective, organised care. We examined if overcrowding in the hospital system was associated with negative changes in stroke outcome. Methods: Data on overcrowding were obtained from the Irish Nurses and Midwives Organisation (INMO) 'Trolley Count' database recording the number of patients cared for on trolleys/chairs in all acute hospitals each midnight. These were compared with quarterly data from the Irish National Audit of Stroke from 2013 to 2021 inclusive. Variables analysed were inpatient mortality rate, thrombolysis rate for ischaemic stroke, median door to needle time and median length of stay. Results: 579449 patient episodes were recorded by Trolley Watch over the period, (Quarterly Median 16719.5, range 3389–27015). Average Quarterly Thrombolysis rate was 11.3% (sd 1.3%) Median Quarterly Inpatient Mortality rate was 11.8% (Range 8.9-14.0%). Median Quarterly Length of stay was 9 days (8–11 days). Median quarterly door to needle was 65 min (45–80 min). Q1 was typically the worst for overcrowding with on average 19777 incidences (sd 4786). This was significantly higher than for Q2 (mean 13540 (sd 4785) p = 0.005 t-test) and for Q3 (mean 14542 (sd 4753) p = 0.03). No significant correlation was found between quarterly Trolley watch episodes and inpatient mortality (r = 0.084, p = 0.63), median length of stay r=-0.15, p = 0.37) or thrombolysis rate (r = 0.089 p = 0.61). There was an unexpected significant negative correlation between trolley watch data and median door to needle time (r=-0.36, p = 0.03). Conclusion: Despite increasing hospital overcrowding, stroke services still managed to preserve standard of care. We could find no association between levels of overcrowding and deterioration in selected indices of patient care. [ABSTRACT FROM AUTHOR]

Background: Stroke is a severe complication of infective endocarditis (IE), associated with high rates of mortality. Data on how IE patients with and without stroke differ may help to improve understanding contributing mechanisms. Methods: All patients treated for IE between 2019 and 2021 with and without associated stroke were identified from the medical records of three academic tertiary care hospitals in Germany, all part of Charité – Universitätsmedizin Berlin, Germany. Multivariable logistic regression analyses were performed to identify variables associated with the occurrence of stroke. Results: The study population consisted of 353 patients diagnosed with IE. Concomitant stroke occurred in 96/353 (27.2%) patients. Acute stroke was independently associated with co-occurring extracerebral arterial embolism [adjusted Odds ratio (aOR = 2.52; 95% confidence interval (CI) 1.35–4.71)], acute liver failure (aOR = 2.62; 95% CI 1.06–6.50), dental focus of infection (aOR = 3.14; 95% CI 1.21–8.12) and left-sided IE (aOR = 28.26; 95% CI 3.59-222.19). Stroke was found less often in IE patients with congenital heart disease (aOR = 0.20; 95% CI 0.04–0.99) and atypical pathogens isolated from blood culture (aOR = 0.31; 95% CI 0.14–0.72). Conclusions: Stroke is more likely to occur in individuals with systemic complications affecting other organs, too. Special attention should be addressed to dental status. The low incidence of stroke in patients with congenital heart disease may reflect awareness and prophylactic measures. [ABSTRACT FROM AUTHOR]

Background and Purpose: In acute ischemic stroke (AIS) due to large‐vessel occlusion (LVO), the relationship between cerebral oxygen extraction fraction (OEF) as the hallmark of the ischemic penumbra and leptomeningeal collateral supply is not well established. We aimed to investigate the relationship between pial collateralization and tissue oxygen extraction in patients with LVO using magnetic resonance imaging (MRI). Methods: Data from 14 patients with anterior circulation LVO who underwent MRI before acute stroke treatment were analyzed. In addition to diffusion‐weighted imaging and perfusion‐weighted imaging (PWI), the protocol comprised sequences for multiparametric quantitative blood‐oxygen‐level‐dependent imaging for the calculation of relative OEF (rOEF). Pial collateral supply was quantitatively assessed by analyzing the signal variance in T2*‐weighted PWI time series. Relationships between collateral supply, infarct volume, rOEF in peri‐infarct hypoperfused tissue, and clinical stroke severity were assessed. Results: The PWI‐based parameter quantifying collateral supply was negatively correlated with baseline ischemic core volume and rOEF in the hypoperfused peri‐infarct area (p <.01). Both reduced collateral supply and increased rOEF correlated significantly with higher scores on the National Institutes of Health Stroke Scale (p <.05). Increased rOEF within hypoperfused tissue was associated with higher baseline (p =.043) and follow‐up infarct volume (p =.009). Conclusions: Signal variance‐based mapping of collaterals with PWI depicts pial collateral supply, which is closely tied to tissue pathophysiology and clinical and imaging outcomes. Magnetic‐resonance‐derived mapping of cerebral rOEF reveals penumbral characteristics of hypoperfused tissue and might provide a promising imaging biomarker in AIS. [ABSTRACT FROM AUTHOR]

Given the frequency of stroke worldwide, tools for neuropsychological assessment of patients with acute stroke are needed to identify cognitive impairments, guide rehabilitation efforts and allow for a prognosis of outcome. However, requirements for assessment tools for acute cognitive deficits differ substantially from tests for chronic neuropsychological impairments and screening tools for suspected dementia. The Oxford Cognitive Screen (OCS) has been developed as a quick to administer neurocognitive screening for acute neurological patients providing information on various cognitive domains. It is available in different languages. The present study reports cut‐off scores, parallel‐test reliability and concurrent validity of the German version (D‐OCS). Following standardized language adaptation and translation, the D‐OCS was administered to 100 healthy individuals to generate cut‐off scores (5th percentile). Subsequently, 88 neurological patients were assessed with both versions of the D‐OCS as well as other tests to evaluate reliability and validity of the D‐OCS subscales. In a further study, the D‐OCS was compared to the MoCA test in 65 acute stroke patients revealing comparable sensitivity but also differences between both tools. The cut‐off scores were comparable to other international versions of the OCS. Intraclass correlations were highly significant and document reliability of the D‐OCS subtests. Scores on subtests correlated significantly with independent tests securing validity. Comparison with the MoCA revealed comparable sensitivity and specificity. The D‐OCS is a reliable and valid assessment tool well suited for patients with acute stroke. Differences to the MoCA test are discussed. [ABSTRACT FROM AUTHOR]

Sitting ability is an important prognostic factor for patients with acute stroke. However, the characteristics of trunk muscle activity and weight-bearing during sitting are unclear. Are trunk muscle activity and weight-bearing during static sitting associated with sitting ability in patients with acute stroke? Trunk electromyography and sitting posturography were performed during static sitting in 20 patients with acute stroke. The electromyography measured the bilateral external oblique and erector spinae muscles. The symmetry of muscle activity between the paralyzed and non-paralyzed side was calculated using the Symmetry Index (SI) raw value and absolute value. The activity of each muscle during static sitting was calculated as the percent reference voluntary contraction (%RVC) normalized by the maximum contraction in the sitting position. Sitting posturography was used to calculate the weight-bearing pressure (%) on the paralyzed and non-paralyzed side, and the raw and absolute values of weight-bearing SI were calculated as a representative value. The trunk impairment scale (TIS) for sitting ability and the Berg balance scale (BBS) for basic balance ability were used as primary outcomes. None of the SI of electromyography for each trunk muscle correlated significantly with clinical performance tests. The %RVC of paralyzed and non-paralyzed external oblique muscle negatively correlated with TIS. The absolute SI of weight-bearing was negatively correlated with BBS. This study showed that the amount, but not the symmetry, of external oblique muscle activity during sitting was associated with sitting ability. We also found that the symmetry of the weight-bearing was associated with sitting ability, not the direction, but the absolute amount of deviation. This suggests that it is important to focus on the amount of external oblique muscle activity and weight-bearing deviation during sitting as a measure of sitting ability in patients with acute stroke. • External oblique muscle activity during sitting was correlated with sitting balance. • Absolute asymmetry of sitting weight-bearing was correlated with balance ability. • Direction of sitting weight-bearing did not correlate with sitting balance.

Stroke is a devastating clinical condition characterized by an acute neurological impairment secondary to cerebrovascular disease. Globally, stroke is the second leading cause of mortality and disability, with prominent risk factors including age, hypertension, hyperlipidemia, atrial fibrillation, diabetes, smoking, preexisting vascular anomalies and obesity. Acute neurological deficits are commonly encountered in the inpatient wards. Heightened clinical suspicion and prompt evaluation involving neurological examination and imaging are crucial for effective management. At many hospitals, hospitalists are tasked with managing stroke patients with consultation from neurologists. The management of stroke is constantly evolving as new and advanced therapies emerge. This review of the literature seeks to summarize current practice in stroke management in hopes it is helpful to those hospitalists who care for this patient population frequently. A search of the literature was performed to summarize current research as well as management and therapeutic strategies. [ABSTRACT FROM AUTHOR]

Background: Using two case reports of adult women with moyamoya disease presenting with intracranial hemorrhage from ruptured aneurysms on moyamoya collateral vessels, we aim to demonstrate the potential for effective endovascular treatment navigated by CT angiography, digital subtraction angiography, and flat panel CT. Case 1 Presentation: A 45-year-old female patient with sudden onset of headache, followed by somnolency. CT scan showed a four-ventricle hematocephalus caused by a 27 × 31 × 17 mm hematoma located in the left basal ganglia. Angiography revealed a 3 mm aneurysm on hypertrophic lenticulostriate artery bridging the M1 occlusion. Selective catheterization and distal embolisation with acrylic glue was done. Case 2 Presentation: A 47-year-old woman was admitted for a sudden onset of severe headache, CT scan showed four-ventricle hematocephalus. A 4 mm aneurysm on the collateral vessel–anterior chorioidal artery bridging the closure of the terminal segment of the internal carotid artery was diagnosed as the source of bleeding. Selective catheterization and distal embolisation with acrylic glue was done. Conclusions: Selective embolisation of ruptured aneurysms on moya moya collaterals is a simple, effective, and safe procedure when relevant microcatheters are used with imaging software navigation such as 3D DSA, 3D road map and flat-panel CT.

Endovascular therapy (ET) significantly improves outcomes for acute ischemic stroke (AIS) patients, but complications such as stroke-associated pneumonia (SAP) increase mortality and healthcare costs. This study investigates the association between blood-brain barrier (BBB) disruption and the increased risk of SAP and explores the relationship between BBB disruption and medium-term functional outcomes.Methods: The retrospective cohort study was performed on AIS patients enrolled between January 2019 to February 2023 who underwent ET. Patients were divided into two groups: BBB disruption and without BBB disruption. Multiple logistic regression model was conducted to measure the association between BBB disruption and SAP. Mediation analysis was used to estimate the potential mediation effects on the associations of BBB disruption with SAP. A restricted cubic spline (RCS) regression model was used to further outline the connection between the highest CT value of hyperattenuated lesions areas and the risk of SAP.Results: The study included 254 patients who underwent endovascular therapy, with 155 patients in the BBB disruption group (exposure) and 99 patients in the without BBB disruption group (control). Multiple logistic regression analysis revealed a significantly increased risk of SAP in patients with BBB disruption (OR = 2.337, 95% CI: 1.118– 4.990, p = 0.025). Furthermore, mediation analysis suggested that this association may be partly due to malignant cerebral oedema and haemorrhagic transformation. The study found an inverse L-shaped dose-response relationship between the maximum CT values of BBB disruption areas and the incidence of SAP. SAP partially mediated the association between BBB disruption and 3-month poor functional outcome.Conclusion: BBB disruption are a potential risk factor for SAP. BBB disruption may affect short- and medium-term prognosis of patients after ET in part through SAP.Keywords: acute stroke, stroke-associated pneumonia, hyperattenuated lesions, endovascular therapy, blood-brain barrier disruption

Background and Purpose Tenecteplase is a thrombolytic agent with pharmacological advantages over alteplase and has been shown to be noninferior to alteplase for acute ischemic stroke in randomized trials. However, evidence pertaining to the safety and efficacy of tenecteplase in patients from different ethnic groups is lacking. The aim of this systematic review and metaanalysis was to investigate ethnicity-specific differences in the safety and efficacy of tenecteplase versus alteplase in patients with acute ischemic stroke. Methods Following an International Prospective Register of Systematic Reviews (PROSPERO)- registered protocol (CRD42023475038), three authors conducted a systematic review of the PubMed/MEDLINE, Embase, Cochrane Library, and CINAHL databases for articles comparing the use of tenecteplase with any thrombolytic agent in patients with acute ischemic stroke up to November 20, 2023. The certainty of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework. Two independent authors extracted data onto a standardized data collection sheet. A pairwise meta-analysis was conducted in risk ratios (RR). Results From 34 studies (59,601 participants), the rate of complete recanalization was significantly higher (P

Introduction. This study is relevant due to the high prevalence of organic brain pathology and the negative influence of urination disorders on the quality of life.Objective. To analyse the impaired function of lower urinary tracts in patients with organic brain pathology.Materials & methods. We analysed 607 patients with severe organic brain pathology (105 had traumatic spinal cord injury (TSCI) and 457 had consequences of acute stroke (AS)). We performed clinical urological examinations. During the survey, attention was paid to the presence of urinary tract pathology at the examining time and anamnesis. Structural changes in the urinary tract were objectively assessed. We objectively assessed structural changes in urinary tracts including prostate adenoma in men, insufficiency of pelvic floor muscles in women and strictures of the urethra or ureters. The degree of the spastic syndrome was assessed with the Ashworth Scale. The neurourological examination included cystometry with the measurement of bladder volume and post-void residual urine. The cognitive status of the patients was assessed with the MMSE (Mini-Mental State Examination) questionnaire. The correlation analysis between the degree of spastic syndrome measured with the Ashworth Scale and urination disorders was performed with Spearman rank correlation.Results. All patients had neurogenic dysfunction of the lower urinary tract. A combination of bladder retention and emptying disorders was found in 62 men older than 45yo with benign prostate hyperplasia (10,2% of all cases). An impaired accumulation function in history was found in 45 women older than 45yo (7,4% of all observations). The level of spasticity was 3 or 4 points on the Ashworth Scale in patients with TSCI and 2 to 4 points in those with AS. The analysis of correlations between the degree of spasticity and urination disorders showed a moderate relationship (r = 0,4) in patients with TSCI and a medium relationship (r = 0.65) in patients with AS.Conclusion. Neurogenic dysfunction of the lower urinary tract accompanies patients with severe organic brain pathology throughout their life and requires adequate correction.

Altered mental status (AMS) is a syndrome posing substantial burden to patients in the intensive care unit (ICU) in both prevalence and intensity. Unfortunately, ICU patients are often diagnosed merely with syndromic labels, particularly the duo of toxic–metabolic encephalopathy (TME) and delirium. Before applying a nonspecific diagnostic label, every patient with AMS should be evaluated for specific, treatable diseases affecting the central nervous system. This review offers a structured approach to increase the probability of identifying specific causal etiologies of AMS in the critically ill. We provide tips for bedside assessment in the challenging ICU environment and review the role and yield of common neurodiagnostic procedures, including specialized bedside modalities of diagnostic utility in unstable patients. We briefly review two common etiologies of TME (uremic and septic encephalopathies), and then review a selection of high-yield toxicologic, neurologic, and infectious causes of AMS in the ICU, with an emphasis on those that require deliberate consideration as they elude routine screening. The final section lays out an approach to the various etiologies of AMS in the critically ill. [ABSTRACT FROM AUTHOR]

The burden of simultaneous acute code stroke activation (ACSA) is not known. We aim to assess the effect of simultaneous ACSA on workflow metrics and home time at 90 days in patients undergoing reperfusion therapies in the emergency department. Simultaneous ACSA was defined as code activation within 60 min of the arrival of any patient receiving intravenous thrombolysis, within 150 min of the arrival of any patient receiving endovascular thrombectomy, within 45 min of the arrival of any patient receiving no reperfusion therapies (based on mean local door-to-needle and door-to-puncture times). Simultaneous ACSA was further graded as 1, 2 and 3. We assessed workflow metrics as door-to-CT (DTC) time, in minutes, and functional outcome as home time at 90 days. A total of 2605 patients were assessed as ACSA at a mean ± SD activations of 130.8 ± 17.1/month and 859 (33%) were simultaneous. Among all ACSA, 545 (20.9%) underwent acute reperfusion therapy with a mean age of 70.6 ± 14.2 years, 45.9% (n = 254) were female with a median (IQR) NIHSS of 13 (8–18). A total of 220 (40.4%) patients underwent simultaneous treatments. The median DTC time, in minutes, was prolonged in grade 3 simultaneous ACSA (18 (13, 28)) compared to non-simultaneous ACSA (15 (11, 21) β = 0.23, p < 0.0001). There was no difference in the median home time at 90 days between the simultaneous (58, 0–84.5 days) and non-simultaneous (54, 0–85 days) patients. Simultaneous ACSA is frequent in patients receiving acute reperfusion therapies. An optimal workflow in high-volume centers may help mitigate the clinical and system burden associated with simultaneity.

Abstract Functional electrical stimulation (FES) can support functional restoration of a paretic limb post-stroke. Hebbian plasticity depends on temporally coinciding pre- and post-synaptic activity. A tight temporal relationship between motor cortical (MC) activity associated with attempted movement and FES-generated visuo-proprioceptive feedback is hypothesized to enhance motor recovery. Using a brain–computer interface (BCI) to classify MC spectral power in electroencephalographic (EEG) signals to trigger FES-delivery with detection of movement attempts improved motor outcomes in chronic stroke patients. We hypothesized that heightened neural plasticity earlier post-stroke would further enhance corticomuscular functional connectivity and motor recovery. We compared subcortical non-dominant hemisphere stroke patients in BCI-FES and Random-FES (FES temporally independent of MC movement attempt detection) groups. The primary outcome measure was the Fugl-Meyer Assessment, Upper Extremity (FMA-UE). We recorded high-density EEG and transcranial magnetic stimulation-induced motor evoked potentials before and after treatment. The BCI group showed greater: FMA-UE improvement; motor evoked potential amplitude; beta oscillatory power and long-range temporal correlation reduction over contralateral MC; and corticomuscular coherence with contralateral MC. These changes are consistent with enhanced post-stroke motor improvement when movement is synchronized with MC activity reflecting attempted movement.

Abstract Objectives The purpose of this study was to investigate the preferred modes of transportation to the hospital among patients with acute stroke and acute myocardial infarction (AMI), as well as to identify the factors that influence the utilization of ambulances. Methods We conducted a cross-sectional study, including patients who were diagnosed with acute stroke and AMI, at the people’s hospital of Zhongjiang, from September 30th, 2022 to August 30th, 2023. All patients were divided into emergency medical service (EMS)-activation group and self-transportation group. Chi-square and t-tests were utilized to discern differences between groups at baseline. To screen relevant variables, we employed the Least Absolute Shrinkage and Selection Operator (LASSO) regression analysis using R package glmnet. Subsequently, we performed a logistic regression analysis to identify predictors of EMS activation according the results of LASSO regression. Results we collected 929 valid questionnaires. 26.16% of the patients required the services of EMS. 90.9% of individuals have not received any formal first aid education. 42.1% of them reported that they had no understanding of cardiovascular and cerebrovascular diseases. Diagnosed as AMI (OR 0.22, 95%CI 0.06 to 0.88) or acute cerebral infarction (OR 0.26, 0.10 to 0.68), the distance between the patient and the nearest 120 network hospital when the patient had these symptoms (OR 0.97, 0.94 to 0.99), the patient’s son or daughter was there when the patient was symptomatic (OR 0.58, 0.37 to 0.94), the patient (OR 0.19, 0.05 to 0.72) and the patient’s partner (wife or husband) (OR 0.36, 0.16 to 0.85) had decided that the patient needed further medical help, Among patients who did not seek immediate help after symptom onset, thinking that the symptoms will disappear spontaneously (OR 0.34, 0.13 to 0.92) or not wanting to disturb others (OR 0.06, 0.01 to 0.66) or believing that they are not important symptoms (OR 0.15, 0.05 to 0.42) were factors independently associated with less ambulance use. Age (OR 1.02, 1.00 to 1.04), Stroke patients have experienced symptoms of disturbance of consciousness or convulsions (OR 2.99, 1.72 to 5.2) were independent factors associated with increased ambulance use. Conclusion There is still ambulance underutilization among patients with acute stroke and AMI in county territory of China. Moreover, it is needed to raise the level of first aid education and awareness about EMS. Additionally, private clinic doctors and the public should gain adequate understanding of the severity of acute stroke and AMI, as well as their common symptoms, the crucial importance of prompt medical intervention. Finally, we propose that all township hospitals should be integrated into the 120 emergency networks and equipped with emergency first aid capabilities, pre-hospital care, and transportation abilities.

Abstract 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.

Stroke is a leading cause of mortality worldwide and a major cause of disability having a high burden on patients, society, and caregiving systems. This study was conducted to investigate the presence of clusters of in-hospital patients with acute stroke based on demographic and clinical data. Cluster analysis reveals patterns in patient characteristics without requiring knowledge of a predefined patient category or assumptions about likely groupings within the data.

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.

Functional electrical stimulation (FES) can support functional restoration of a paretic limb post-stroke. Hebbian plasticity depends on temporally coinciding pre- and post-synaptic activity. A tight temporal relationship between motor cortical (MC) activity associated with attempted movement and FES-generated visuo-proprioceptive feedback is hypothesized to enhance motor recovery. Using a brain–computer interface (BCI) to classify MC spectral power in electroencephalographic (EEG) signals to trigger FES-delivery with detection of movement attempts improved motor outcomes in chronic stroke patients. We hypothesized that heightened neural plasticity earlier post-stroke would further enhance corticomuscular functional connectivity and motor recovery. We compared subcortical non-dominant hemisphere stroke patients in BCI-FES and Random-FES (FES temporally independent of MC movement attempt detection) groups. The primary outcome measure was the Fugl-Meyer Assessment, Upper Extremity (FMA-UE). We recorded high-density EEG and transcranial magnetic stimulation-induced motor evoked potentials before and after treatment. The BCI group showed greater: FMA-UE improvement; motor evoked potential amplitude; beta oscillatory power and long-range temporal correlation reduction over contralateral MC; and corticomuscular coherence with contralateral MC. These changes are consistent with enhanced post-stroke motor improvement when movement is synchronized with MC activity reflecting attempted movement. [ABSTRACT FROM AUTHOR]

Background: Mechanical thrombectomy (MT) is the gold standard treatment for large vessel occlusion (LVO). A vital factor that might influence MT outcomes is the use of intravenous thrombolysis (IVT). A few clinical trials in this domain thus far have not yielded consistent outcomes. We conducted this meta-analysis to synthesize collective evidence in this regard. Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement guidelines were followed, and we performed a comprehensive literature search of four databases (PubMed, Scopus, Web of Science, Cochrane CENTRAL). For outcomes constituting continuous data, the mean difference (MD) and its standard deviation (SD) were pooled. For outcomes constituting dichotomous data, the frequency of events and the total number of patients were pooled as the risk ratio (RR). Results: Seven clinical trials with a total of 2317 patients are included in this meta-analysis. Six trials are randomized, and one trial was nonrandomized. No significant differences were found between MT plus IVT and MT alone in successful recanalization (RR 1.04, 95% Confidence Interval (CI) [0.92 to 1.17], P = 0.53), 90-day functional independence (RR 1.03, 95% CI [0.90 to 1.19], P = 0.65), symptomatic intracranial hemorrhage (sICH) (RR 1.22, 95% CI [0.84 to 1.75], P = 0.30), or mortality (RR 0.94, 95% CI [0.76 to 1.18], P = 0.61). Conclusion: The current evidence does not favor either MT plus IVT or MT alone for LVO except for the procedural time. More trials are needed in this regard, and certain factors should be considered when comparing the two approaches. [ABSTRACT FROM AUTHOR]

Background: We aim to assess the association between procedural time and outcomes in patients in unsuccessful mechanical thrombectomy (MT) for anterior circulation acute stroke. Methods: We conducted a cohort study on prospectively collected data from patients with M1 and/or M2 segment of middle cerebral artery occlusion with a thrombolysis in cerebral infarction 0–1 at the end of procedure. Primary outcome was 90-day poor outcome. Secondary outcomes were early neurological deterioration (END), symptomatic intracranial hemorrhage (sICH) according to ECASS II and sICH according to SITS-MOST. Results: Among 852 patients, after comparing characteristics of favourable and poor outcome groups, logistic regression analysis showed age (OR: 1.04; 95%CI: 1.02–1.05; p < 0.001), previous TIA/stroke (OR: 0.23; 95%CI: 0.12–0.74; p = 0.009), M1 occlusion (OR: 1.69; 95%CI: 1.13–2.50; p = 0.01), baseline NIHSS (OR: 1.01; 95%CI: 1.06–1.13; p < 0.001) and procedural time (OR:1.00; 95% CI: 1.00–1.01; p = 0.003) as independent predictors poor outcome at 90 days. Concerning secondary outcomes, logistic regression analysis showed NIHSS (OR:0.96; 95%CI: 0.93–0.99; p = 0.008), general anaesthesia (OR:2.59; 95%CI: 1.52–4.40; p < 0.001), procedural time (OR: 1.00; 95% CI: 1.00–1.01; p = 0.002) and intraprocedural complications (OR: 1.89; 95%CI: 1.02–3.52; p = 0.04) as independent predictors of END. Bridging therapy (OR:2.93; 95%CI: 1.21–7.09; p = 0.017) was associated with sICH per SITS-MOST criteria whereas M1 occlusion (OR: 0.35; 95%CI: 0.18–0.69; p = 0.002), bridging therapy (OR: 2.02; 95%CI: 1.07–3.82; p = 0.03) and intraprocedural complications (OR: 5.55; 95%CI: 2.72–11.31; p < 0.001) were independently associated with sICH per ECASS II criteria. No significant association was found between the number of MT attempts and analyzed outcomes. Conclusions: Regardless of the number of MT attempts and intraprocedural complications, procedural time was associated with poor outcome and END. We suggest a deeper consideration of procedural time when treating anterior circulation occlusions refractory to MT. [ABSTRACT FROM AUTHOR]

Introduction: To better target stroke awareness efforts (pre and post first stroke) and thereby decrease the time window for help-seeking, this study aims to assess quantitatively whether stroke awareness is associated with appropriate help-seeking at symptom onset, and to investigate qualitatively why this may (not) be the case. Methods: This study conducted in a German regional stroke network comprises a convergent quantitative-dominant, hypothesis-driven mixed methods design including 462 quantitative patient questionnaires combined with qualitative interviews with 28 patients and seven relatives. Quantitative associations were identified using Pearson's correlation analysis. Open coding was performed on interview transcripts before the quantitative results were used to further focus qualitative analysis. Joint display analysis was conducted to mix data strands. Cooperation with the Patient Council of the Department of Neurology ensured patient involvement in the study. Results: Our hypothesis that stroke awareness would be associated with appropriate help-seeking behaviour at stroke symptom onset was partially supported by the quantitative data, i.e. showing associations between some dimensions of stroke awareness and appropriate help-seeking, but not others. For example, knowing stroke symptoms is correlated with recognising one's own symptoms as stroke (r = 0.101; p = 0.030*; N = 459) but not with no hesitation before calling help (r = 0.003; p = 0.941; N = 457). A previous stroke also makes it more likely to recognise one's own symptoms as stroke (r = 0.114; p = 0.015*; N = 459), but not to be transported by emergency ambulance (r = 0.08; p = 0.872; N = 462) or to arrive at the hospital on time (r = 0.02; p = 0.677; N = 459). Qualitative results showed concordance, discordance or provided potential explanations for quantitative findings. For example, qualitative data showed processes of denial on the part of patients and the important role of relatives in initiating appropriate help-seeking behaviour on patients' behalf. Conclusions: Our study provides insights into the complexities of the decision-making process at stroke symptom onset. As our findings suggest processes of denial and inabilities to translate abstract disease knowledge into correct actions, we recommend to address relatives as potential saviours of loved ones, increased use of specific situational examples (e.g. lying on the bathroom floor) and the involvement of patient representatives in the preparation of informational resources and campaigns. Future research should include mixed methods research from one sample and more attention to potential reporting inconsistencies. [ABSTRACT FROM AUTHOR]

Objective: Acute reperfusion therapy is a critical intervention for stroke patients with the aim of restoring blood flow. The presence of anatomical anomalies, such as fetal posterior cerebral artery (fPCA) and posterior communicating artery (PCOM) variations, can impact treatment outcomes and patient prognosis. This study aimed to assess the potential influence of these anomalies on patients undergoing acute reperfusion therapy. Materials and Methods: Demographic characteristics of patients who underwent acute reperfusion therapy for stroke were considered among three distinct groups: the PCOM group, fPCA group, and control group. The demographic attributes examined for each group included gender distribution, mean age, presence of comorbidities, thrombolysis in cerebral infarction, national institutes of health stroke scale (NIHSS), and European cooperative acute stroke study II (ECASS II) scores. The significance of differences in these attributes among the groups was assessed. Results: The study included a total of 106 patients: 42 patients in the PCOM group, 31 patients in the fPCA group, and 33 patients in the control group. No significant differences in demographic data were observed among the groups. The greatest decrease in NIHSS at the 24th hour was observed in the PCOM group, whereas the least decrease on day 7 was observed in the fPCA group. No differences were detected in the NIHSS values on the 24th hour and 7th day among the groups. When the 24th hour computed tomography scans of the groups were evaluated according to the ECASS II criteria, no significant differences were observed among the groups. Hemorrhage was not observed in 52.4% of patients in the PCOM group and 66.7% of patients in the control group. Conclusion: The impact of fPCA and PCOM anomalies on patients undergoing acute reperfusion therapy for stroke was evaluated. Although no significant demographic differences were found among the groups, the study highlights the importance of further research to better understand their potential impact on treatment outcomes.

Reperfusion therapy, employed in the treatment of acute stroke, frequently proves to be inadequate in addressing the primary brain tissue injury and may even give rise to secondary damage. The study introduces a satellite nanoparticle platform named MEps, which combine the neural repair properties of bone marrow mesenchymal stem cell exosomes (Exos) with the inflammatory site‐targeting abilities of macrophage membranes (MMs). MMs and Exos in MEps act like satellites, ensuring precise positioning and information transmission. MEps rapidly form a protective barrier on the damaged cerebral vascular endothelial cells through the interaction of adhesion molecules with their receptors, blocking the infiltration of neutrophils. Subsequently, repair factors in Exos repair the damaged cells and initiate neurogenesis. The results indicate that this innovative approach effectively mitigates ischemic‐reperfusion injury at multiple levels and demonstrates strong biocompatibility. This strategy holds promise for clinical applications in alleviating ischemic‐reperfusion injury. [ABSTRACT FROM AUTHOR]

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.

Objectives: The purpose of this study was to investigate the preferred modes of transportation to the hospital among patients with acute stroke and acute myocardial infarction (AMI), as well as to identify the factors that influence the utilization of ambulances. Methods: We conducted a cross-sectional study, including patients who were diagnosed with acute stroke and AMI, at the people's hospital of Zhongjiang, from September 30th, 2022 to August 30th, 2023. All patients were divided into emergency medical service (EMS)-activation group and self-transportation group. Chi-square and t-tests were utilized to discern differences between groups at baseline. To screen relevant variables, we employed the Least Absolute Shrinkage and Selection Operator (LASSO) regression analysis using R package glmnet. Subsequently, we performed a logistic regression analysis to identify predictors of EMS activation according the results of LASSO regression. Results: we collected 929 valid questionnaires. 26.16% of the patients required the services of EMS. 90.9% of individuals have not received any formal first aid education. 42.1% of them reported that they had no understanding of cardiovascular and cerebrovascular diseases. Diagnosed as AMI (OR 0.22, 95%CI 0.06 to 0.88) or acute cerebral infarction (OR 0.26, 0.10 to 0.68), the distance between the patient and the nearest 120 network hospital when the patient had these symptoms (OR 0.97, 0.94 to 0.99), the patient's son or daughter was there when the patient was symptomatic (OR 0.58, 0.37 to 0.94), the patient (OR 0.19, 0.05 to 0.72) and the patient's partner (wife or husband) (OR 0.36, 0.16 to 0.85) had decided that the patient needed further medical help, Among patients who did not seek immediate help after symptom onset, thinking that the symptoms will disappear spontaneously (OR 0.34, 0.13 to 0.92) or not wanting to disturb others (OR 0.06, 0.01 to 0.66) or believing that they are not important symptoms (OR 0.15, 0.05 to 0.42) were factors independently associated with less ambulance use. Age (OR 1.02, 1.00 to 1.04), Stroke patients have experienced symptoms of disturbance of consciousness or convulsions (OR 2.99, 1.72 to 5.2) were independent factors associated with increased ambulance use. Conclusion: There is still ambulance underutilization among patients with acute stroke and AMI in county territory of China. Moreover, it is needed to raise the level of first aid education and awareness about EMS. Additionally, private clinic doctors and the public should gain adequate understanding of the severity of acute stroke and AMI, as well as their common symptoms, the crucial importance of prompt medical intervention. Finally, we propose that all township hospitals should be integrated into the 120 emergency networks and equipped with emergency first aid capabilities, pre-hospital care, and transportation abilities.

Introduction: Acute stroke rehabilitation is crucial for achieving good functional recovery, even during the coronavirus disease 2019 (COVID-19) pandemic. This study aimed to clarify the impact of the COVID-19 pandemic on acute stroke rehabilitation and identify which components in the acute stroke rehabilitation provision system were susceptible to the pandemic. Methods: A web-based questionnaire survey was conducted in all primary stroke centers (PSCs) in Japan between February 7 and April 21, 2022. The survey included questions about the current status of acute stroke rehabilitation and the influence of the pandemic. We classified the influences and investigated the relationship between the influence of the pandemic and the provision of rehabilitation. Additionally, we investigated a group of prefectures divided according to the grade of the pandemic. Results: The survey response rate was 67% (639 of 959 PSCs). Among them, 387 PSCs (61%) reported that the COVID-19 pandemic affected acute stroke rehabilitation. In PSCs affected by the pandemic, more rehabilitation-related staff were working, and the proportion of weekend/holiday rehabilitation implementation was higher compared to those unaffected. In PSCs from highly infected prefectures, no significant relationship was observed between the influence of the pandemic and the rehabilitation provision system. Conclusions: PSCs that provide denser acute stroke rehabilitation may be affected to a greater extent by the pandemic. We conclude that stroke hospitals should formulate infection control procedures for acute stroke rehabilitation in advance, depending on the conditions of the region and facility.

Background and Objectives: Dysphagia is a common complication following stroke. It corresponds to the development of pneumonia, which is always associated with bad prognosis, longer hospital stays and increased mortality. The aim of the study was to assess the impact of physical therapy intervention of dysphagia on preventing pneumonia in acute stroke patients. Methods: A single‐blind randomized controlled trial was carried out on 70 ischemic stroke patients with oropharyngeal dysphagia, age ranged from 49 to 65 years. They were randomly assigned to two groups (control and study) of equal number. Patients in the control group received oral care and nasogastric tube feeding, while patients in the study group received the same program in addition to the designed physical therapy program (exercises and neuromuscular electrical stimulation). The intervention program was applied for 40 min/session, 1 session/day, and 5 days/week for 4 weeks. Gugging swallowing screen (GUSS), and stroke associated pneumonia (SAP) control and prevention criteria were used to assess dysphagia and incidence of pneumonia at baseline, after two and 4 weeks of intervention for both groups. Results: Before treatment, all patients were susceptible to pneumonia after two and 4 weeks of intervention; there were a significant increase in GUSS score in both groups with more improvement in favor of the study group (p < 0.05) and a statistically significant increase in incidence of SAP after 2 weeks of intervention only in the control group (p < 0.05). The results also showed a significant negative correlation between GUSS score and SAP (r = − 0.3662, p = 0.0018) Implications for Physiotherapy Practice: adding physical therapy (exercise therapy and neuromuscular electrical stimulation) to oral care and nasogastric tube feeding is effective in improving oropharyngeal dysphagia and decreasing the incidence of aspiration pneumonia in acute ischemic stroke patients.

Background: COVID-19 has significantly increased morbidity and mortality in Indonesia, particularly at Gambiran General Hospital in Kediri, East Java, following the WHO's pandemic declaration. The global incidence of acute stroke with COVID-19 is 1.4%, presenting varying clinical features from mild to severe outcomes, and even death. The identification of specific biomarkers, such as elevated D-dimer serum levels, is crucial for predicting severe complications in acute stroke patients with COVID-19. Objective: This study aimed to explore the correlation between elevated levels of mild, moderate, and severe D-dimer serum and mortality in acute stroke patients with COVID-19. Methods: Conducted as an observational analytical study using a cross-sectional approach, this research utilized secondary data from medical records at Kediri Gambiran General Hospital (March 2020 to June 2023). Inclusion and exclusion criteria were applied to hospitalized patients, categorized based on D-dimer levels: normal, mild, moderate, and severe. Statistical analyses, including the Spearman correlation test and Chi-square correlation test, were employed to assess the relationship between D-dimer levels and total mortality. Results: Among the 101 enrolled patients, 53 were male (52.48%), with 90 exhibiting elevated D-dimer levels. Out of these, 44 patients died. The Spearman correlation test showed a non-significant value of 0.069 (p>0.005). The Chi-square correlation test for mild, moderate, and severe D-dimer levels on total mortality also yielded a non-significant value of 0.878. Conclusion: This study found no significant relationship between elevated levels of mild, moderate, and severe D-dimer serum and mortality in acute stroke patients with COVID-19 at Gambiran General Hospital.

Frailty in older individuals is an underappreciated condition that affects the incidence and/or prognosis of stroke. We evaluated the prevalence of pre-onset frailty in patients with acute first-onset and recurrent strokes and association between pre-onset frailty and functional disability at hospital discharge. This prospective cohort study included 210 acute stroke patients admitted to the Stroke Unit of Nippon Medical School Hospital during November 2021–June 2022. The mean participant age was 79.2 ± 7.4 years. Age, sex, pre-onset frailty, body mass index (BMI), stroke type, medical history, and National Institutes of Health Stroke Scale (NIHSS) score at admission were evaluated. Frailty was defined as a clinical frailty scale (CFS) score ≥ 5. Frailty prevalence was calculated for all patients, and scores of functional disabilities at discharge were evaluated using modified Rankin scale. Overall frailty prevalence was 31% in all stroke patients, with 24% and 47% of first-onset and recurrent strokes, respectively. Pre-onset frailty, NIHSS score at admission, age, stroke type, previous stroke, sex, BMI, dyslipidemia, and atrial fibrillation were significantly associated with functional disability at discharge. Logistic regression analysis revealed that CFS score, NIHSS score at admission, and previous stroke were independent predictors of functional disability at discharge. Approximately one-fourth of patients with first-onset stroke had pre-onset frailty; the rate doubled in recurrent stroke; these rates appear to be much larger than rate in healthy individuals. Pre-onset frailty, a negative independent factor affecting functional disability at discharge, is important for pre-onset frailty evaluation and rehabilitation intervention in acute stroke patients.

Background: Automated pupillometry (AP) is a handheld, non-invasive tool that is able to assess pupillary light reflex dynamics and is useful for the detection of intracranial hypertension. Limited evidence is available on acute ischemic stroke (AIS) patients. The primary objective was to evaluate the ability of AP to discriminate AIS patients from healthy subjects (HS). Secondly, we aimed to compute a predictive score for AIS diagnosis based on clinical, demographic, and AP variables. Methods: We included 200 consecutive patients admitted to a comprehensive stroke center who underwent AP assessment through NPi-200 (NeurOptics®) within 72 h of stroke onset and 200 HS. The mean values of AP parameters and the absolute differences between the AP parameters of the two eyes were considered in the analyses. Predictors of stroke diagnosis were identified through univariate and multivariate logistic regressions; we then computed a nomogram based on each variable's β coefficient. Finally, we developed a web app capable of displaying the probability of stroke diagnosis based on the predictive algorithm. Results: A high percentage of pupil constriction (CH, p < 0.001), a low constriction velocity (CV, p = 0.002), and high differences between these two parameters (p = 0.036 and p = 0.004, respectively) were independent predictors of AIS. The highest contribution in the predictive score was provided by CH, the Neurological Pupil Index, CV, and CV absolute difference, disclosing the important role of AP in the discrimination of stroke patients. Conclusions: The results of our study suggest that AP parameters, and in particular, those concerning pupillary constriction, may be useful for the early diagnosis of AIS. [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]

This study is aimed to evaluate the proficiency of emergency physicians in identifying ischemic strokes via diffusion-weighted magnetic resonance imaging (DW-MRI), and to determine the inter-rater agreement between emergency department (ED) residents and radiologists. The suspected ischemic stroke patients undergoing DW-MRI and not the candidates for thrombolytic therapy were eligible for the study. Diffusion MRI images were evaluated by the on-duty senior ED residents having two or more years in residency program, and a radiologist. Prior to the study, an instructor from radiology department delivered 2-hour theoretical and 2-hour practical lectures to ED physicians on the evaluation of diffusion MRI. A total of 604 patients were included in the study wherein 145 patients (24%) were detected with ischemic areas. The parietal lobe was the most prevalent ischemic area according to ED physicians’ and radiologist’s findings. ED residents and the radiologist had different interpretations for 54 patients. ED physicians ascribed 15 (3.4%) ischemic stroke patients as normal and 39 (23.1%) normal patients as stroke. ED physicians had 89.7% sensitivity (95% confidence interval (CI): 84% to 94%) and 91.5% specificity (95% CI: 89% to 94%) in diagnosing ischemic stroke. A good inter-rater agreement was found between ED physicians and the radiologist with kappa value of 0.77 (95% CI: 0.71 to 0.83). ED physicians have better success rate in interpreting DW-MRI to detect ischemic stroke in non-candidate cases of thrombolytic therapy (cases whose National Institutes of Health Stroke Skale (NIHSS) score is not appropriate, symptom onset exceeds 4.5 hours, and thrombolytic administration is contraindicated). There is a good inter-rater agreement between ED physicians and radiologist. [ABSTRACT FROM AUTHOR]

Objective: To estimate prevalence of dysphagia in first time hemorrhagic or ischemic (both thrombotic and embolic) acute stroke patients also to determine the impact of (age, sex and severity of illness) on post stroke dysphagia. Methods: Two hundred patients (152 ischemic, 48 hemorrhagic) with first ever acute stroke were recruited. Detailed history and neurological examination were done for each one of the patients. The National Institute of Health Stroke Scale (NIHSS) was used to determine the severity of stroke while swallowing was screened by Gugging swallowing screen (GUSS) which is the only screening tool for dysphagia which uses multiple consistencies for testing swallowing function. Results: Fifty-four (27%) of hemorrhagic and ischemic stroke patients had post stroke dysphagia, 35 (23.03%) from group with ischemia, 19 (39.6%) from group with hemorrhage. Age of dysphagic patients was higher than non-dysphagic patients while it was higher in ischemic patients than hemorrhagic patients. The mean total NIHSS score was higher in dysphagic patients and was higher in hemorrhagic ones. Severity of dysphagia was significantly correlated with stroke severity and age of the patient. Conclusion: The frequency of post-stroke dysphagia (27%) is near the results of the previous studies in literature. Severity of dysphagia is higher in ischemic stroke. Old age and severity of stroke were the main determinant of severity of dysphagia. [ABSTRACT FROM AUTHOR]

Background and purpose: The diagnosis and management of acute fetal posterior cerebral artery occlusion are challenging. While endovascular treatment is established for anterior circulation large vessel occlusion stroke, little is known about the course of acute fetal posterior cerebral artery occlusions. We report the clinical course, radiological findings and management considerations of acute fetal posterior cerebral artery occlusion stroke. Methods: We performed a retrospective review of consecutive patients presenting with acute large vessel occlusion who underwent cerebral angiogram and/or mechanical thrombectomy between January 2015 and January 2021. Patients diagnosed with fetal posterior cerebral artery occlusion were included. Demographic data, clinical presentation, imaging findings and management strategies were reviewed. Results: Between January 2015 and January 2021, three patients with fetal posterior cerebral artery occlusion were identified from 400 patients who underwent angiogram and/or mechanical thrombectomy for acute stroke (0.75%). The first patient presented with concomitant fetal posterior cerebral artery and middle cerebral artery occlusions. Thrombectomy was performed with recanalisation of the fetal posterior cerebral artery but the patient died from malignant oedema. The second patient presented with isolated fetal posterior cerebral artery occlusion. No endovascular intervention was performed and the patient was disabled from malignant posterior cerebral artery infarct. The third patient presented with carotid occlusion and was found to have fetal posterior cerebral artery occlusion after internal carotid artery recanalisation. No further intervention was performed. The patient was left with residual contralateral homonymous hemianopia and mild left sided weakness. Conclusion: Fetal posterior cerebral artery occlusion is a rare, but potentially disabling, cause of ischaemic stroke. Endovascular treatment is feasible. Further investigation is needed to compare the efficacy of medical versus endovascular management strategies. [ABSTRACT FROM AUTHOR]

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]

Introduction: Stroke is the second leading cause of death and the third leading cause of disability worldwide. Nurses play a crucial role in providing care for stroke patients. Accurate and precise nursing diagnoses serves as the foundation for providing appropriate nursing care. This study aims to identify nursing diagnoses in acute stroke patients based on the Indonesian Nursing Diagnosis Standards. Method. This study utilized a descriptive research design. The research sample consisted of 471 patients (205 hemorrhagic strokes; 266 ischemic strokes) selected through random sampling techniques. The data were collected from the medical records of stroke patients treated at the Emergency Department of Muhammadiyah Lamongan Hospital from January to December 2023. The research instrument employed was a summary sheet, and data were analyzed descriptively. Result. The results of this study indicate that common signs and symptoms in hemorrhagic stroke patients included headache, decreased level of consciousness, and increased blood pressure with widened pulse pressure. The most frequent nursing diagnoses observed were decreased intracranial adaptive capacity (87.3%), impaired physical mobility (70.7%), and verbal communication impairment (74.1%). Similarly, common signs and symptoms in ischemic stroke patients include difficulty moving extremities, decreased range of motion (ROM), and decreased muscle strength. The most frequent nursing diagnoses observed were impaired physical mobility (81.5%), risk for falls (57.5%), and decreased intracranial adaptive capacity (49.6%). Conclusion: There are differences in signs and symptoms between hemorrhagic stroke and ischemic stroke during the acute phase, as well as differences in primary nursing diagnoses. However, these distinctions may vary in subsequent phases depending on the severity of the disease and underlying comorbidities. Future researchers are encouraged to conduct real-time studies to promptly identify any missing data.

Background Among patients with stroke eligible for endovascular treatment, preprocedure identification of those with low chances of successful recanalization with conventional devices (stent‐retrievers and/or direct aspiration) may allow anticipating procedural rescue strategies. We aimed to develop a preprocedural algorithm able to predict recanalization failure with conventional devices (RFCD). Methods Observational study. Data from consecutive patients with stroke who received endovascular treatment between 2019 and 2022 in 10 centers were collected from the Catalan Stroke Registry (Codi Ictus Catalunya Registry, CICAT). RFCD was defined as final thrombolysis in cerebral infarction ≤2a or the use of rescue therapy defined as balloon angioplasty±stent deployment. Univariate and multivariate analysis to identify variables associated with RFCD were performed. A gradient boosted decision tree machine learning model to predict RFCD was developed utilizing preprocedure variables previously selected. Clinical improvement at 24 hours was defined as a drop of ≥4 points from baseline National Institutes of Health Stroke Scale score or 0–1 at 24 hours. Results In total, 984 patients were included; RFCD was observed in 14.3% (n:141) of the cases. Of these, 47.5% (n = 67) received balloon angioplasty±stent deployment as rescue therapy. Among patients receiving balloon angioplasty±stent deployment, clinical improvement was associated with lower number of attempts with conventional devices (median number of passes 2 versus 3; P = 0.045). In logistic regression, the absence of atrial fibrillation (odds ratio [OR]: 2.730, 95%CI: 1.541–4.836; P = 0.007) and no‐thrombolytic treatment (OR: 1.826, 95%CI: 1.230–2.711; P = 0.003) emerged as independent predictors of RFCD. A predictive model for RFCD, based on age, sex, hypertension, wake‐up stroke, baseline National Institutes of Health Stroke Scale score, Alberta Stroke Program Early CT [Computed Tomography] Score, occlusion site, thrombolysis, and atrial fibrillation showed an acceptable discrimination (area under the curve: 0.72±0.024 SD) and accuracy (0.75±0.015 SD). Overall performance was moderate (weighted F1‐score: 0.77±0.041 SD). Conclusion In RFCD patients, early balloon angioplasty±stent deployment rescue was associated with improved outcomes. A predictive model using affordable preprocedure clinical variables could be useful to identify these patients before intervention.

Background Left atrial (LA) fibrosis is a marker of atrial cardiomyopathy and has been reported to be associated with both atrial fibrillation and ischemic stroke. Elucidating this relationship is clinically important as LA fibrosis could serve as a surrogate biomarker of LA cardiomyopathy. The objective of this study is to investigate the association of LA fibrosis and embolic stroke of undetermined source (ESUS) using cardiac magnetic resonance imaging. Methods and Results Following an International Prospective Register of Systematic Reviews‐registered protocol, 3 blinded reviewers performed a systematic review for studies that quantified the degree of LA fibrosis in patients with ESUS as compared with healthy patients from inception to February 2024. A meta‐analysis was conducted in the mean difference. From 7 studies (705 patients), there was a significantly higher degree of LA fibrosis in patients with ESUS compared with healthy controls (MD, 5.71% [95% CI, 3.55%–7.87%], P

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy (CADASIL) is caused by mutations in the NOTCH3 gene. Clinical manifestations of CADASIL include lacunar infarcts, transient ischemic attacks, dementia, migraine, and psychiatric disorders.Cerebral MRI can show signal abnormalities in the basal ganglia and white matter, especially characteristic when located in the anterior part of the temporal lobe and external capsules. We report CADASIL patient treated with intravenous tenectelase for acute ischemic stroke, and we present a review of literature aimed to report effectiveness and safety of intravenous thrombolysis in CADASIL patients.
