OBJECTIVE: Outcomes for weekend surgical interventions are associated with higher rates of mortality and complications compared to weekday interventions. While prior investigations have reported the \'weekend effect\' for carotid endarterectomy (CEA), this association remains unclear for Transcarotid Artery Revascularization (TCAR) and Transfemoral Carotid Artery Stenting (TFCAS). We investigated the weekend effect for all three carotid revascularization methods.
METHODS: We queried the Vascular Quality Initiative (VQI) for patients undergoing CEA, TCAR, and TFCAS between 2016-2022. Chi-square and logistic regression modeling analyzed outcomes including in-hospital stroke, death, MI, and 30-day mortality by weekend vs. weekday intervention. Backward stepwise regression was utilized to identify significant confounding variables and were ultimately included in each final logistic regression model. Logistic regression of outcomes was substratified by symptomatic status. Secondary multivariable analysis compared outcomes between the three revascularization methods by weekend vs. weekday interventions.
RESULTS: 155,962 procedures were analyzed including 103,790 CEA, 31,666 TCAR and 20,506 TFCAS. Of these, 1988 CEA, 246 TCAR and 820 TFCAS received weekend interventions. Logistic regression demonstrated no significant differences for TCAR, and increased odds of in-hospital stroke/death/MI for CEA [OR:1.31,(1.04-1.65)] and TFCAS [OR:1.46,(1.09-1.96)] weekend procedures. Asymptomatic TCAR patients had nearly triple the odds of 30-day mortality [OR:2.85,(1.06-7.68), P=0.038]. Similarly, odds of in-hospital death were nearly tripled for asymptomatic CEA [OR:2.89,(1.30-6.43), P=0.009] and asymptomatic TFCAS [OR:2.78,(1.34-5.76), P=0.006] patients. Secondary analysis demonstrated that CEA and TCAR had no significant differences for all outcomes. TFCAS was associated with increased odds of stroke and death compared to CEA and TCAR.
CONCLUSIONS: In this observational cohort study, we found that weekend carotid revascularization is associated with increased odds of complications and mortality. Furthermore, asymptomatic weekend patients perform worse in the CEA and TFCAS procedural groups. Among the three revascularization methods, TFCAS is associated with the highest odds of perioperative stroke and mortality. As such, our findings suggest that TFCAS procedures should be avoided over the weekend, in favor of CEA or TCAR. In patients who are poor candidates for CEA, TCAR offers the lowest morbidity and mortality for weekend procedures.

Ischemic stroke (IS) remains one of the most serious threats to human life. Early blood-brain barrier damage (BBB) is the cause of parenchymal cell damage. Repair of the structure and function of the BBB is beneficial for the treatment of IS. The traditional prescription ginseng aconitum decoction (GAD) has a long history in the treatment of cardiovascular and cerebrovascular diseases, however, the effect of GAD on the BBB disruption and underlying mechanisms remains largely unknown. To address these issues, in vitro models of BBB were established with brain endothelial cells (bEnd.3). We found that GAD reduced the leakage of the fluorescent probe FITC-dextran (P < 0.01) and increased the expression of tight junction proteins (Claudin-5, ZO-1) (P < 0.05) in the BBB model in vitro. Furthermore, to investigate the BBB protective effects of GAD in vivo. A total of 25 male C57/BL6 mice (20-22 g) were randomly divided into 5 groups (n = 5 per group): (1) Sham group (saline), (2) MCAO group (saline), (3) MCAO + CG group (Chinese ginseng 8 mg/kg/day), (4) MCAO + AC group (aconite 8 mg/kg/day), (5) MCAO + GAD group (GAD 8 mg/kg/day).We constructed IS model in mice and found that GAD treatment reduced IgG leakage (P < 0.05), up-regulated the expression of tight junction proteins Claudin-5, Occludin, and ZO-1 (P < 0.05). Further mechanism study showed that fatty acid oxidation (FAO) of vascular endothelial cells is involved in the protection of the BBB after cerebral IS, and GAD regulates FAO (P < 0.05) to protect BBB. In addition, we found the effect of GAD was stronger than that of Chinese ginseng (CG) (P < 0.05) and aconite (AC) (P < 0.01) alone. We concluded that GAD ameliorated the BBB dysfunction by regulating FAO involving vascular endothelial cells after IS. At the same time, the prescription is more effective than single traditional Chinese medicine.

After ischemic stroke (IS), secondary injury is intimately linked to endoplasmic reticulum (ER) stress and body-brain crosstalk. Nonetheless, the underlying mechanism systemic immune disorder mediated ER stress in human IS remains unknown. In this study, 32 candidate ER stress-related genes (ERSRGs) were identified by overlapping MSigDB ER stress pathway genes and DEGs. Three Key ERSRGs (ATF6, DDIT3 and ERP29) were identified using LASSO, random forest, and SVM-RFE. IS patients with different ERSRGs profile were clustered into two groups using consensus clustering and the difference between 2 group was further explored by GSVA. Through immune cell infiltration deconvolution analysis, and middle cerebral artery occlusion (MCAO) mouse scRNA analysis, we found that the expression of 3 key ERSRGs were closely related with peripheral macrophage cell ER stress in IS and this was further confirmed by RT-qPCR experiment. These ERS genes might be helpful to further accurately regulate the central nervous system and systemic immune response through ER stress and have potential application value in clinical practice in IS.

OBJECTIVE: The purpose of this study was to evaluate the effectiveness of Governor vessel acupuncture (GV Ac) in treating post-stroke cognitive impairment (PSCI).
METHODS: There was a total of seven databases examined. Four English databases (Cochrane Library, PubMed, Embase, and Medline) and three Chinese databases (Chinese National Knowledge Infrastructure (CNKI), Chinese Science and Technology Periodical Databases (VIP), and Wan Fang Database) contain all randomized controlled trials (RCTs) comparing Governor vessel acupuncture to other treatments or none acupuncture for PSCI. The exact dates for the search period are from January 1, 2000, to January 1, 2023.Two researchers independently reviewed the literature, gathered RCT data, and performed statistical analysis. All data were analyzed using Review Manager software (Rev Man) 5.3.
RESULTS: This meta-analysis includes a total of 39 trials with 2044 patients. There were 1022 participants in each of the test and control groups. Following 12-120 days of acupuncture treatment, a meta-analysis revealed that the treatment groups (GV Ac combined with conventional treatment groups) significantly increased their scores on the Curative ratio (OR=3.00, 95%CI=2.37-3.79, P=0.98, I²=0%), Montreal Cognitive Assessment (MoCA)(MD=1.82, 95%CI=1.60-2.03, P=0.11, I²=25%), Mini-Mental State Examination (MMSE)(MD=2.18, 95%CI=1.64-2.72, P<0.005, I²=92%), and Activity of Daily Living (ADL)(MD=5.99, 95%CI=5.33-6.64, P=0.19, I²=26%).
CONCLUSIONS: The results suggested that acupuncture on points of the Governor vessel enhanced cognitive function in stroke survivors.

OBJECTIVE: Recent work on ischemic cerebellar stroke has suggested that the resection of infarcted tissue may lead to improved functional outcomes compared with decompressive surgery alone. Nonetheless, no studies have assessed the extent to which necrotic tissue should be resected or if there are any volumetric thresholds capable of predicting functional outcomes in this patient population. In this study, the authors aimed to determine potential thresholds for volume reduction in ischemic cerebellar stroke in an effort to optimize the management of ischemic cerebellar stroke and, in so doing, improve functional outcomes.
METHODS: This study is a multicentric retrospective study of patients who underwent surgery for the management of ischemic cerebellar stroke. Volumetric analyses of infarcted tissue present on CT scans were performed before and after surgical intervention(s). The final infarct volume (FIV) was computed as a percentage of the initial infarct volume (postoperative infarct volume/preoperative infarct volume × 100). The primary endpoint was functional outcome at 3 months, as determined by the modified Rankin Scale (mRS) score; mRS scores 0-2 were considered as favorable and mRS scores 3-6 as unfavorable. Receiver operating characteristic curves were used to explore the relationship between postoperative infarct volumes and FIV versus mRS score, and Youden\'s index was used to estimate potential volumetric thresholds.
RESULTS: A total of 91 patients were included in the study. The mean pre- and postoperative infarct volumes were 45.25 (SD 18.32) cm3 and 29.56 (SD 26.61) cm3, respectively. Patients undergoing necrosectomy, regardless of whether via craniotomy or craniectomy, were more likely to have a favorable outcome at discharge (OR 16.62, 95% CI 2.12-130.33; p = 0.008) and at 3 months (OR 24.12, 95% CI 3.03-192.18; p = 0.003) postoperatively. Postoperative infarct volumes ≤ 17 cm3 yielded a sensitivity of 77% and a specificity of 68% with regard to the prediction of favorable outcome at 3 months. The resection ≥ 50% of infarcted tissue was also predictive of favorable outcomes at 3 months (OR 7.7, 95% CI 2.7-21.8; p < 0.001).
CONCLUSIONS: The reduction of necrotic tissue volumes by at least 50% and/or the reduction of the infarct volume by ≤ 17 cm3 appear to be associated with favorable outcomes in patients with surgically managed ischemic cerebellar strokes.

OBJECTIVE: Anticoagulation can prevent stroke and prolong lives in patients with atrial fibrillation (AF); However, anticoagulated patients with AF remain at risk of death. The aim of this study was to investigate the causes of death and factors associated with all-cause and cardiovascular death in the XANTUS population.
RESULTS: Causes of death occurring within a year after rivaroxaban initiation in patients in the XANTUS program studies were adjudicated by a central adjudication committee and classified following international guidance.Baseline characteristics associated with all-cause or cardiovascular death were identified. Of 11,040 patients, 187 (1.7%) died. Almost half of these deaths were due to cardiovascular causes other than bleeding (n = 82, 43.9%), particularly heart failure (n = 38, 20.3%) and sudden or unwitnessed death (n = 24, 12.8%). Fatal stroke (n = 8, 4.3%), which was classified as a type of cardiovascular death, and fatal bleeding (n = 17, 9.1%) were less common causes of death. Independent factors associated with all-cause or cardiovascular death included age, AF type, body mass index, left ventricular ejection fraction, hospitalization at baseline, rivaroxaban dose, and anaemia.
CONCLUSIONS: The overall risk of death due to stroke or bleeding was low in XANTUS. Anticoagulated patients with AF remain at risk of death due to heart failure and sudden death. Potential interventions to reduce cardiovascular deaths in anticoagulated patients with AF, require further investigation, e.g. early rhythm control therapy and AF ablation.

Background Young stroke survivors are likely to be discharged home from acute hospital care without rehabilitation more quickly than older survivors, but it is not clear why. File-audit studies capturing real-world clinical practice are lacking for this cohort. We aimed to compare characteristics and care pathways of young and older survivors and describe stroke presentations and predictors of pathways of care in young survivors (≤45years), including a focus on care received for \'invisible\' (cognitive, psychological) difficulties. Methods A retrospective audit of 847 medical records (67 young stroke survivors, mean age=36years; 780 older patients, mean age=70years) was completed for stroke survivors admitted to an Australian tertiary hospital. Stroke characteristics and presence of cognitive difficulties (identified through clinician opinion or cognitive screening) were used to predict length of stay and discharge destination in young stroke survivors. Results There were no differences in length of stay between young and older survivors, however, young stroke survivors were more likely to be discharged home without rehabilitation (though this may be due to milder strokes observed in young stroke survivors). For young stroke survivors, stroke severity and age predicted discharge destination, while cognitive difficulties predicted longer length of stay. While almost all young survivors were offered occupational therapy and physiotherapy, none received psychological input (clinical, health or neuropsychology). Conclusions Cognitive and psychological needs of young stroke survivors may remain largely unmet by a service model designed for older people. Findings can inform service development or models of care, such as the new Australian Young Stroke Service designed to better meet the needs of young survivors.

Prevalence rates for both depression and insomnia the first year after stroke are around 30%, significantly impacting the prospects of recovery, rehabilitation, and quality of life. Furthermore, the risk of insomnia and depression becoming chronic is high in the subacute phase post-stroke. This cross-sectional observational study investigated whether insomnia and depression are related in the subacute phase post-stroke, using validated instruments. Sixty-six outpatient stroke survivors participated. Depression was measured using the depression subscale of the Hospital Anxiety and Depression Scale (HADS-D) and insomnia severity with the Insomnia Severity Index (ISI). A multiple linear regression analysis was used to examine the association between the dependent variable post-stroke depression and the independent variables insomnia and pre-stroke depression treatment. Results showed that insomnia (β = 0.48, t = 4.40, p < 0.001) and pre-stroke depression treatment (β = 0.24, t = 2.28, p = 0.026) were both significant predictors of depression. Participants with more insomnia complaints and participants with pre-stroke depression treatment had more depression symptoms post-stroke. Therefore, it is important to be alert in the subacute phase post-stroke of both, insomnia and depression complaints.

BACKGROUND: Trunk control is the basic component of postural control, and achieving trunk control is a complex process that can be achieved by dynamically building and maintaining neuromuscular function. Lateropulsion, which is also defined as the body falling to one side, is considered an important condition that is frequently encountered after stroke and affects trunk control. It is known that there are differences in the regulation of postural control and trunk control according to hemispheric localization. We had a very specific group of patients and tried to find out the outcomes prospectively in this study.
METHODS: The patients were divided into 2 groups those with right hemisphere lesions (Group 1) and those with left hemisphere lesions (Group 2). Comorbidity and cognitive function were evaluated using the Charlson Comorbidity Index (CMI) and Standardized Mini-Mental State Test (SMMSE). Activities of daily living were evaluated using the Turkish version of the Modified Barthel Index (MBI). The Stroke Rehabilitation Assessment of Movement Instrument (STREAM) test was used to assess trunk control and the Brunnstrom (BS) test was used to assess motor functions.
RESULTS: There was a significant difference between Groups 1 and 2 in terms of STREAM in lower extremity scores were higher in Group 2 (P < .05). The number of patients in BS lower extremity Stages IV-VI was higher in Group 1 and Group 2 (P < .05). It was determined that upper extremity, lower extremity and Total STREAM scores and BS Hand stage in Group 2 were significantly higher than Group 1 in patients with total middle cerebral artery (MCA) affected(P < .05).
CONCLUSIONS: It was determined that trunk control was more affected in patients with right hemispheric lesions. Additionally, trunk control is significantly affected in patients with total MCA lesions.

BACKGROUND: Dyskinesia is one of the most common complications of stroke. Acupuncture therapy (AT) and mirror therapy (MT) are promising rehabilitation measures for the treatment of post-stroke dyskinesia. Although some studies suggested that AT and MT are effective and safe for dyskinesia, the effects, and safety remain uncertain due to lacking strong evidence. The purpose of this study is to investigate the efficacy and safety of AT combined with MT in the treatment of post-stroke dyskinesia.
METHODS: We searched the following databases: PubMed, Web of Science, Cochrane Library, EMBASE, Medline, China Knowledge Network, WANFANG, and China Biomedical Literature Database, from inception to 1 January 2023 to identify eligible studies. Total effective rate, the Fugl-Meyer assessment scale (FMA) upper and lower limb scores, modified Barthel index scores, Berg balance scale, modified Ashworth scale, and adverse reactions were adopted as outcome indicators. The Grading of Recommendations Assessment Development and Evaluation system was used by 2 independent reviewers to assess the quality of evidence for the outcome indicators included in the study. The statistical analysis was conducted by RevMan V.5.4 software.
RESULTS: A total of 24 randomized controlled studies included 2133 patients with post-stroke dyskinesia were included. The total effective rate of AT combined with MT was more advantageous in the treatment of post-stroke dyskinesia (relative risk = 1.31, 95% confidence interval [CI] [1.22-1.42], Z = 6.96, P < .0001). AT combined with MT was more advantageous for FMA upper limb score (mean difference [MD] = 6.67, 95% CI [5.21-8.13], Z = 8.97, P < .00001) and FMA lower limb score (MD = 3.72, 95% CI [2.81-4.63], Z = 7.98, P < .00001). Meta-analysis showed that AT combined with MT for post-stroke dyskinesia had a more advantageous modified Barthel index score (MD = 9.51, 95% CI [7.44-11.58], Z = 9.01, P < .00001).
CONCLUSIONS: AT combined with MT is effective in improving motor function and daily living ability of patients, especially in improving muscle spasms. However, these results should be regarded with caution given the low quality of evidence for the evaluation results.
