Effects of aerobic and resistance exercises on psychological and cognitive functions in patients with post-stroke migraine

ABSTRACT Objective To investigate the impact of a combination of aerobic and resistance exercises on the psychological and cognitive functions of post-stroke migraine patients. Methods This study recruited 100 patients suffering from post-stroke migraine pain who were admitted to the hospital, categorizing them into a control group (n = 50) and an intervention group (n = 50). The control group received conventional drug treatment, while the intervention group received the exercise-based intervention that combined aerobic exercise with resistance exercise. Results Before treatment, both groups displayed similar Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), Mini-mental State Examination (MMSE) and MoCA scores. However, after the intervention, the intervention group exhibited lower scores on these measures compared to the control group (all p < 0.05). Additionally, there were no discernible disparity in Migraine Disability Assessment (MIDAS) and Headache Impact Test (HIT-6) scores between the two cohorts of patients before treatment (p > 0.05), whereas the intervention group demonstrated significantly lower MIDAS and HIT-6 scores following the intervention (p < 0.05). Although there were no discernible distinctions in National Institute of Health stroke scale (NIHSS) and Stroke Specialized Quality of Life Scale (SS-QOL) measurements between the two patient groups before treatment (p > 0.05), the intervention group exhibited a significant decrease in NIHSS scores and a notable increase in SS-QOL scores after the intervention (p > 0.05). Moreover, the satisfaction rate and overall satisfaction rate were significantly higher in the intervention group (p < 0.05). Conclusion The combination of aerobic and resistance exercises demonstrated positive effects on the psychological well-being and overall quality of life for post-stroke migraine patients.

Postinterventional Petechial Hemorrhage Associated With Poor Functional Outcome After Successful Recanalization Following Endovascular Therapy.

Endovascular therapy (EVT) has emerged as the standard for treating patients with acute ischemic stroke due to large vessel occlusion. The aim of this study was to investigate the relationship between early petechial hemorrhage and patient outcomes after successful EVT of anterior circulation. We retrospectively analyzed multicenter data from 316 patients who underwent EVT for acute occlusion of anterior circulation. Patients were divided into petechial hemorrhage group and without hemorrhage group based on post-EVT head imaging. Logistical regression analysis was performed to determine independent predictors for petechial hemorrhage, and for petechial hemorrhage as a predictor of early neurological improvement, favorable outcome at 90 days (modified Rankin Scale 0-2), and 90-day mortality, with adjustment for all factors significantly associated with these endpoints in univariate regression to P < .10. Of 316 included patients with successful EVT, 49 (15.50%) had petechial hemorrhage. The petechial hemorrhage group showed less early neurological improvement (36.73% compared with 53.56%, P = .030), less favorable outcomes at 90 days (32.65% compared with 61.80%, P < .001, absolute risk difference 29.15%), and higher mortality at 90 days (28.57% compared with 10.49%, P = .001) then the group without hemorrhage. Petechial hemorrhage was inversely associated with favorable 90-day outcome (odds ratio = 0.415, 95% CI 0.206-0.835) and higher mortality rate at 90 days (odds ratio = 2.537, 95% CI 1.142-5.635) in multivariable regression but was not independently associated with early neurological improvement. In patients with anterior large vessel occlusion who underwent successful EVT, petechial hemorrhage was associated with poor functional outcome and 90-day mortality when adjusted for complete recanalization, pre-EVT National Institute of Health Stroke Scale/Score, and Alberta Stroke Program Early Computed Tomography Score. Despite the relatively lower rate of a favorable 90-day outcome with petechial hemorrhage compared with no petechial hemorrhage, the absolute rate of a favorable outcome exceeds the natural history of medical management for this condition.

A cross-sectional analysis of the relationship between ischemic stroke and uric acid in young people in highland areas.

To investigate the relationship between serum uric acid (SUA) levels and ischemic stroke in young patients in the Ganzi Tibetan plateau area. A cross-sectional survey was undertaken from January 2020 to June 2023 involving young patients (age: 15-45 years) diagnosed with ischemic stroke. The survey was conducted at the Department of Internal Medicine of the People's Hospital of Derong County, Ganzi Prefecture. The participants underwent a comprehensive assessment, including questionnaire surveys, physical examinations, laboratory tests, and head computed tomography (CT) examinations. Based on the tertiles of serum uric acid (SUA) levels, the patients were stratified into three groups. Furthermore, stroke severity was classified into mild (1-4 points), moderate (5-15 points), and severe (>15 points) categories using the National Institute of Health Stroke Scale. The severe stroke group exhibited higher levels of age, glucose, systolic blood pressure, serum triglyceride, low-density lipoprotein cholesterol, and serum uric acid (SUA) compared to the mild stroke group (P < 0.05). Furthermore, the likelihood of male sex, advanced age, smoking, and a family history of stroke, diabetes mellitus, and heart disease were significantly elevated in the severe stroke group compared to the moderate stroke group (P < 0.05). Multivariate logistic regression analysis conducted on young adults residing in highland areas revealed a significant association between SUA levels and the risk of stroke. Elevated SUA levels serve as a distinct risk factor for the development of a major stroke in young patients in highland areas. At SUA levels of 320.56 mol/L, the risk of a moderate-to-severe stroke is noticeably elevated.

Novel inflammatory biomarkers associated with stroke severity: results from a cross-sectional stroke cohort study

BackgroundStroke is a leading cause of mortality and disability worldwide and its occurrence is expected to increase in the future. Blood biomarkers have proven their usefulness in identification and monitoring of the disease. Stroke severity is a major factor for estimation of prognosis and risk of recurrent events, but knowledge on respective blood biomarkers is still scarce. Stroke pathophysiology comprises a multitude of ischemia-induced inflammatory and immune mediated responses. Therefore, the assessment of an immune-related panel in correlation with stroke severity seems promising.MethodsIn the present cross-sectional evaluation, a set of 92 blood biomarkers of a standardized immune panel were gathered (median 4.6 days after admission) and related to stroke severity measures, assessed at hospital admission of acute stroke patients. Multivariable logistic regression models were used to determine associations between biomarkers and modified Rankin Scale (mRS), linear regression models were used for associations with National Institute of Health Stroke Scale.Results415 patients (mean age 69 years; 41% female) were included for biomarker analysis. C-type lectin domain family 4 member G (CLEC4G; OR = 2.89, 95% CI [1.49; 5.59], padj = 0.026, Cytoskeleton-associated protein 4 (CKAP4; OR = 2.38, 95% CI [1.43; 3.98], padj = 0.019), and Interleukin-6 (IL-6) (IL6; OR = 1.97, 95% CI [1.49; 2.62], padj < 0.001) were positively associated with stroke severity measured by mRS, while Lymphocyte antigen 75 (LY75; OR = 0.37, 95% CI [0.19; 0.73], padj = 0.049) and Integrin alpha-11 (ITGA11 OR = 0.24, 95% CI [0.14, 0.40] padj < 0.001) were inversely associated. When investigating the relationships with the NIHSS, IL-6 (β = 0.23, 95% CI [0.12, 0.33] padj = 0.001) and ITGA11 (β = − 0.60, 95% CI [− 0.83, − 0.37] padj < 0.001) were significantly associated.ConclusionsHigher relative concentrations of plasma CLEC4G, CKAP4, and IL-6 were associated with higher stroke severity, whereas LY75 and ITGA11 showed an inverse association. Future research might show a possible use as therapeutic targets and application in individual risk assessments.

Prognostic markers for ischemic stroke - are they truly reliable?

Stroke is one of the leading causes of mortality and morbidity worldwide. Despite extensive research, to this date there is no panel of biomarkers for the prevention and prognosis of ischemic stroke and there is still much incomplete and insufficiently researched information. We conducted a prospective, observational study between January and June 2020. The main objective of this study was to clarify the role of inflammation markers, i.e. neutrophil/ lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), high-sensitivity C - reactive protein (hsCRP) in ischemic stroke and whether there is or not a correlation between these markers and carotid stenosis. In the study we included 150 subjects divided in two groups: study group - 100 subjects and control group - 50 subjects. Data collected during the research (at the time of patient admission): 1) biological sample: 5 ml of peripheral blood were collected in a vial with clot activator and separating gel, from which the following laboratory tests were performed: hsCRP, neutrophils, lymphocytes, platelets. NLR and PLR were subsequently calculated as the ratio of neutrophils to lymphocytes, respectively platelets and lymphocytes), 2) paraclinical examinations: extracranial carotid Doppler ultrasound examination. The results were impressive: high-sensitivity C reactive protein (hsCRP), neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR) were strongly, respectively moderately correlated with the severity of stroke (the severity being established with the NIHS (National Institute of Health Stroke) score. None of the inflammation markers included in the present study was correlated with carotid stenosis. hsCRP, NLR and PLR may potentially be prognostic markers for ischemic stroke, being of major help in preventing its possible complications.

The acute-to-chronic glycemic ratio correlates with the severity of illness at admission in patients with diabetes experiencing acute ischemic stroke.

Acute hyperglycemia is a powerful indicator of the severity of acute ischemic stroke (AIS); however, the relationship between these two factors is not very clear in patients with diabetes. We aimed to retrospectively evaluate data from 335 consecutive patients who experienced AIS from November 2015 to November 2016 to investigate whether a comprehensive assessment of blood glucose levels is a more valuable indicator of the severity of AIS or the presence of acute hyperglycemia in patients with diabetes. We collected demographic data, clinical manifestation information, clinical scores, and laboratory data [including fasting blood glucose and glycated hemoglobin (HbA1c) levels]. We estimated prehospital mean blood glucose concentrations using the following formula [1.59 * HbA1c (%) - 2.59] to calculate the "Acute-to-Chronic Glycemic Ratio" (AC ratio). The AC ratio differed significantly among patients grouped according to the National Institutes of Health Stroke Scale/Score (NIHSS) at admission (admission NIHSS) (p = 0.006). Univariate regression analysis revealed a correlation between the AC ratio and admission NIHSS [standardized β-coefficient (Std. B) = 0.164, p = 0.004]. The adjusted linear regression analysis revealed a correlation between both HbA1c (Std. B = 0.368, p = 0.038) and the AC ratio (Std. B = 0.262, p = 0.022) and admission NIHSS. The AC ratio (Std. B = 0.161, p = 0.012) was related to admission NIHSS in the stepwise variable selection. For an admission NIHHS > 4, the AC ratio (Std. B = 0.186, p = 0.047) was related to admission NIHSS in the stepwise variable selection. The AC ratio (Std. B = 1.163, p = 0.006 and Std. B = 0.565, p = 0.021, respectively) were related to admission NIHSS in both large-artery atherosclerosis (LAA) and small-vessel occlusion (SVO) subgroups. Thus, the AC ratio is related to admission NIHSS in patients with diabetes who experienced AIS and may be a better indicator of severity than acute blood glucose levels.

ENDOVASCULAR INTERVENTION FOR ACUTE ISCHEMIC STROKE AT CAN THO UNIVERSITY OF MEDICINE AND PHARMACY HOSPITAL

Introduction: Acute cerebral ischemic stroke is a life-threatening emergency with high incidence of mortality and morbidity. Endovascular revascularization has been increasingly used as one of the treatment options. In this article, we report our outcomes of endovascular intervention for the treatment of ischemic stroke and highlight some technical experiences. Materials and methods: A cross-sectional descriptive study was conducted on all cerebral ischemic stroke patients who came to Can Tho University of Medicine and Pharmacy Hospital within 8 hours from the first symptom would be included. National Institute of health stroke (NIHSS) scale was used for stroke grading which should be 10 or above. The vascularization procedure would be performed with the thrombus aspiration systems or stent retrievers with or without angioplasty and stenting. Postprocedure care would be conducted for at least 2 weeks before discharge. Results: A total of 53 patients were recruited from 1st of January 2018 to 30th December 2020 (24 months). Male to female ratio was 1.54:1. Ages ranged from 38 to 90 (mean 64). NIHSS scores ranged from 12-25. Approximately 98% of patients had comorbidities with hypertension, diabetes, atrial fibrillation , mitral valve stenosis and valvular insufficiency, A-V block. Totally there were 44 patients experiencing thrombectomy with catheter-based distal aspiration (35), stent retrievers (03), aspiration and stent retriever combination (06). The total technical success rates for all procedures were 47/53 (88.6%)). The total death rate was 15/53 (28.3%) due to combining comorbiditiese. There were 31/53 patients (58.4%) who had significant recovered in muscle movement, language and cognition after 2 weeks. Conclusion: Endovascular intervention is a one of the good options for the management of acute ischemic stroke, which has a high revascularization rate (88.6%) and can save up to 58.4% of patients out of disability. Successful revascularization is the crucial first step to salvage the patients and obtain a better prognosis.

Early neurological deterioration in acute ischemic stroke patients after intravenous thrombolysis with alteplase predicts poor 3-month functional prognosis - data from the Thrombolysis Implementation and Monitor of Acute Ischemic Stroke in China (TIMS-China)

BackgroundWe aimed to investigate the risk factors of early neurological deterioration (END) after intravenous thrombolysis with recombinant tissue-type plasminogen activator (rt-PA) and the relationship between END and poor 3-month functional outcomes.MethodsPatients who accepted intravenous recombinant rt-PA were enrolled continuously. END was defined as an increase in National Institute of Health Stroke (NIHSS) score ≥ 4 points or death within 24 hours after intravenous thrombolysis. The modified Rankin Scale (mRS) score was recorded to evaluate the functional outcome of stroke, and the poor 3-month prognosis was defined as an mRS score ≥ of 3. Univariate and multivariate analyses were used to analyze the risk factors of END. The relation between END and 3-month functional outcome was analyzed by multivariate logistic regression analysis.ResultsA total of 1107 patients (mean age, 63.42 ± 11.33 years; 673 males) were included in the final analysis, and 81(7.32%) patients had END. In multivariate analysis, the serum glucose level was significantly associated with END; the odds ratio was 1.10 (95% CI 1.03 to 1.18, p = 0.004). The multivariate logistic analysis showed END has a notable association with the poor 3-month functional recovery even after adjusting for confounding factors; the adjusted OR was 8.25 (95% CI 3.77 to 18.03, p < 0.0001).ConclusionsThe initial serum glucose level might be an independent risk factor of END, and END might predict a poor 3-month prognosis.

A.1 Changes in ischemic stroke presentations and associated workflow during the first wave of the COVID-19 pandemic: A population study

Background: Pandemics may promote hospital avoidance among patients with emergencies, and added precautions may exacerbate treatment delays. Methods: We used linked administrative data and data from the Quality Improvement and Clinical Research Alberta Stroke Program – a registry capturing stroke-related data on the entire Albertan population (4.3 million) – to identify all patients hospitalized with stroke in the pre-pandemic (01/01/2016-27/02/2020) and COVID-19 pandemic (28/02/2020-30/08/2020) periods. We examined changes in stroke presentation rates and use of thrombolysis and endovascular therapy (EVT), adjusted for age, sex, comorbidities, and pre-admission care needs; and in workflow, stroke severity (National Institutes of Health Stroke Scale/NIHSS), and in-hospital outcomes. Results: We analyzed 19,531 patients with ischemic stroke pre-pandemic versus 2,255 during the pandemic. Hospitalizations/presentations dropped (weekly adjusted-incidence-rate-ratio[aIRR]:0.48,95%CI:0.46-0.50), as did population-level incidence of thrombolysis (aIRR:0.49,0.44-0.56) or EVT (aIRR:0.59,0.49-0.69). However, proportions of presenting patients receiving thrombolysis/EVT did not decline (thrombolysis:11.7% pre-pandemic vs 13.1% during-pandemic, aOR:1.02,0.75-1.38). For out-of-hospital strokes, onset-to-door times were prolonged(adjusted-coefficient:37.0-minutes, 95%CI:16.5-57.5), and EVT recipients experienced greater door-to-reperfusion delays (adjusted-coefficient:18.7-minutes,1.45-36.0). NIHSS scores and in-hospital mortality did not differ. Conclusions: The first COVID-19 wave was associated with a halving of presentations and acute therapy utilization for ischemic stroke at a population level, and greater pre-/in-hospital treatment delays. Our data can inform public health messaging and stroke care in future pandemic waves.

Clinical Outcomes and Patient Safety of Nasogastric Tube in Acute Stroke Patients

Nasogastric tube (NGT) is often used in stroke patients who are dysphagic (deglutition disorders) or have decreased conscious state. This method of feeding is assumed to have minimal complications. The aim of this study is to analyze complications associated with NGT and variables associated with mortality. Retrospective analysis of 250 acute stroke patients requiring NGT feeding between 2003 and 2020. There were 250 patients (median age 76 (IQR 68–83), 56.4% males, median time to NGT 1 day (IQR 0–3). Discussion with family prior to insertion of NGT recorded in 46 (18.4%). There were 123 cases (49.2%) of aspiration pneumonia. There were 188 (75.2%) NGT associated complications: 67 patients (26.8%) had failed insertion, 31 required multiple attempts, 129 patients (51.6%) pulled out NGT, 107 patients (42.8%) had NGT placed in wrong positions and require reinsertion, 20 cases in the lung, 5 pneumothorax cases, 97 in the gastro oesophageal junction or hiatus hernias, 1 case of oesophageal ulceration, 37 coiled, kinked or resistance. 78 cases the tips were not seen on chest X-ray (CXR), gastrointestinal bleeding in 9 cases, epistaxis in 6 cases), 96 patients (38.4%) required restrain. There were 91 death (36.4%) with 73 patients occurring during hospital admission and a further 18 died within 6 months. Death was more frequent in those age > 60 (72 of 216 patients versus 1 of 33 patients, p < 0.01). The median National Institute of Health Stroke Score/NIHSS of those with aspiration pneumonia was higher than those without (19.5 versus 15, p < 0.01). Decision tree analysis first split at age (≤ 59 versus > 59, p = 0.03), NIHSS (≤ 16 or > 16, p = 0.02), post-stroke pneumonia (p = 0.04) and multiple NGT insertion (p = 0.01). The area under the ROC curve was for this model was 0.75 (95% CI 0.69–0.80). Complications were common among patients with NGT complications. These findings may be used to inform discussions with families regarding NGT.

Applicability of classifier to discovery knowledge for future prediction modelling

The immense growth of new technological interventions has forced researchers and scientists around the globe to adopt the widely anticipated technology of Machine Learning (ML) and Artificial Intelligence (AI). ML and AI have generously prospected itself from the past decade in the discovery of knowledge from databases. Several ML and AI based adoptive technologies have emerged in varied application domains, and are thus widely opening a new era of knowledge in decision making. Moreover, ML and AI are techniques that can improve the treatment and diagnosis of diseases. In the current study, we have designed and deployed a “PROCLAVE”. The tool was designed in varied layers of structure, where each layer plays a significant role in determining the patterns. We have applied several libraries for the processing of a prototype to develop a visualization interface. The tool forecasts health vulnerability, makes a comparison among variable classifiers and visualize the results for end users. Moreover, the proposed architecture is based on the concepts of conceptualization and visualization to detect the overall dashboard. Furthermore, the current approach was synthesized and populated with a database that allows the end users to select the variable features and relatively determine the interactive patterns for the number of cases. The database was collected from the National Institute of Health Stroke (NIHS) in the United States. Data was gathered for stroke patients who were diagnosed with stroke from 1950 to 2015. The study was based on several attributes which included causes of death, sex, race, Hispanic origin and others to discover unknown patterns for future decision making.

Application effect for a care bundle in optimizing nursing of patients with severe craniocerebral injury.

BACKGROUNDSevere craniocerebral injury (STBI) is a critical physical trauma caused by a sudden external force acting on the head. The condition is complex and changeable, and disability and mortality rates are high. Although the life of STBI patients can be saved through treatment, the sequelae of consciousness, speech, cognitive impairment, stiffness, spasm, pain and abnormal behavior in the early rehabilitation stage can be a heavy burden to a family. In the past, routine nursing was often used to treat/manage STBI; however, problems, such as improper cooperation and untimely communication, reduced therapeutic effectiveness.AIMTo investigate the effect of a proposed care bundle to optimize the first aid process and assess its effectiveness on the early rehabilitation nursing of patients with STBI.METHODSFrom January 2019 to December 2020, 126 STBI patients were admitted to the emergency department of Chongqing Emergency Medical Center. These patients were retrospectively selected as the research participants in the current study. The study participants were then divided into a control group (61 cases) and a study group (65 cases). The control group was treated with routine nursing. The study group adopted the proposed care bundle. The National Institutes of Health Stroke Scale/Score and Glasgow Coma Scale (GCS) were used to evaluate neurological function before and after emergency treatment. After 3 mo of rehabilitation, experimental outcomes were assessed. These included the GCS, Barthel Index, complication rate, muscle strength grade and satisfaction.RESULTSThere was no significant difference in gender, age, cause of injury and GCS between the two groups. After emergency, the National Institutes of Health Stroke Scale/Score of the study group (10.23 ± 3.26) was lower than that of the control group (14.79 ± 3.14). The GCS score of the study group (12.48 ± 2.38) was higher than that of the control group (9.32 ± 2.01). The arrival time of consultation in the study group was 20.56 ± 19.12, and the retention time in the emergency room was 45.12 ± 10.21, which were significantly shorter than those in the control group. After 3 mo of rehabilitation management, the GCS and Barthel Index of the study group were 14.56 ± 3.75 and 58.14 ± 12.14, respectively, which were significantly higher than those of the control group. The incidence of complications in the study group (15.38%) was significantly lower than that in the control group (32.79%). The proportion of muscle strength ≥ grade III in the study group (89.23%) was significantly higher than that in the control group (50.82%). The satisfaction of patients in the study group was significantly higher than that in the control group.CONCLUSIONCare bundles are used to optimize the nursing process. During first-aid, care bundles can effectively improve the rescue effect and improve neurological function of STBI patients as well as shorten the treatment time. In early rehabilitation, they can effectively improve the consciousness of STBI patients, improve the activities of daily living, reduce the risk of complications, accelerate the recovery of muscle strength and improve their satisfaction.

Hemorrhagic stroke outcomes of KApSR patients with co-morbid diabetes and Alzheimer's disease.

BackgroundVascular risk factors, such as diabetes mellitus (DM), are associated with poorer outcomes following many neurodegenerative diseases, including hemorrhagic stroke and Alzheimer’s disease (AD). Combined AD and DM co-morbidities are associated with an increased risk of hemorrhagic stroke and increased Medicare costs. Therefore, we hypothesized that patients with DM in combination with AD, termed DM/AD, would have increased hemorrhagic stroke severity.MethodsKentucky Appalachian Stroke Registry (KApSR) is a database of demographic and clinical data from patients that live in Appalachia, a distinct region with increased health disparities and stroke severity. Inpatients with a primary indication of hemorrhagic stroke were selected from KApSR for retrospective analysis and were separated into four groups: DM only, AD only, neither, or both.ResultsHemorrhagic stroke patients (2,071 total) presented with either intracerebral hemorrhage (ICH), n=1,448, or subarachnoid hemorrhage (SAH), n=623. When examining all four groups, subjects with AD were significantly older (AD+, 80.9±6.6 yrs) (DM+/AD+, 77.4±10.0 yrs) than non AD subjects (DM-/AD-, 61.3±16.5 yrs) and (DM+, 66.0±12.5 yrs). A higher percentage of females were among the AD+ group and a higher percentage of males among the DM+/AD+ group. Interestingly, after adjusting for multiple comparison, DM+/AD+ subjects were ten times as likely to suffer a moderate to severe stroke based on a National Institute of Health Stroke (NIHSS) upon admission [odds ratio (95% CI)] compared to DM-/AD- [0.1 (0.02–0.55)], DM+ [0.11 (0.02–0.59)], and AD+ [0.09(0.01–0.63)]. The odds of DM+/AD+ subjects having an unfavorable discharge destination (death, hospice, long-term care) was significant (P<0.05) from DM-/AD- [0.26 (0.07–0.96)] when adjusting for sex, age, and comorbidities.ConclusionsIn our retrospective analysis utilizing KApSR, regardless of adjusting for age, sex, and comorbidities, DM+/AD+ patients were significantly more likely to have had a moderate or severe stroke leading to an unfavorable outcome following hemorrhagic stroke.

Middle Cerebral Artery Thrombectomy: Clinical Findings and Technical Pearls: 2-Dimensional Operative Video.

Mechanical thrombectomy as a treatment for large vessel occlusion to achieve rapid revascularization is supported in the literature.1-3 The presenting symptoms will localize to functions of the ischemic area. The middle cerebral artery (MCA) supplies areas of the frontal, temporal, and parietal cortices, as well as the basal ganglia. Occlusion of the MCA will present with contralateral hemiplegia, sensory loss, and, if the dominant hemisphere is involved, language deficits. We present a right-hand-dominant 79-yr-old female with right MCA syndrome-her last known well time was 1.5 h prior to presentation. Her NIH (National Institutes of Health) Stroke Scale was 16, most notable for left hemiplegia. Although the patient presented early in the clinical time course, as part of our institution protocol, a computed tomography (CT) head, CT perfusion, and CT angiogram (CTA) were performed. CT head did not demonstrate acute hemorrhage, so she received intravenous tissue plasminogen activator. CTA demonstrated a right MCA occlusion and CT perfusion suggested a large area of salvageable tissue, so she was taken to the angiography suite for mechanical thrombectomy. Angiography of the right internal carotid artery (ICA) showed MCA occlusion (insular segment). A thrombectomy device was deployed over the area of occlusion and allowed to engage for 5 min. An aspiration catheter was advanced over the stentriever up against the clot. The stentriever device was withdrawn under continuous aspiration and follow-up angiography showed complete reperfusion. The patient demonstrated improvement and was eventually discharged to an inpatient rehabilitation center. Patient provided consent for photography per university protocol. Institutional review board (IRB) approval was not needed for the single-patient data included in this report.

The use of hypnotherapy as treatment for functional stroke: A case series from a single center in the UK.

BackgroundFunctional neurological disorder is defined by symptoms not explained by the current model of disease and its pathophysiology. It is found in 8.4% of patients presenting as acute stroke. Treatment is difficult and recurrence rates are high. We introduced hypnotherapy as a therapeutic option in addition to standard stroke unit care.MethodsThis is an observational study of successive patients with functional neurological disorder presenting as acute stroke treated with hypnotherapy between 1 April 2014 and 1 February 2018. The diagnosis of functional neurological disorder was confirmed by clinical examination and computed tomography/magnetic resonance imaging. Hypnosis was delivered by a hypnotherapy trained stroke physician using imagery for induction. A positive response was defined as a National Institutes of Health Stroke score reduction to 0 or by ≥4 points posthypnotherapy. Costs were calculated as therapist time and benefits as reduction in disability/bed days.ResultsSixty-eight patients (mean age 36.4 years, 52 (76%) females, mean baseline National Institutes of Health Stroke 5.0 (range 1–9)) were included. Two patients (3%) could not be hypnotized. Fifty-eight 58 (85%) responded, 47 (81%) required one treatment session, while 19% needed up to three sessions for symptomatic improvement. No adverse events were observed. Disability (modified Rankin Scale) reduced from a mean of 2.3 to 0.5 resulting in an average cost saving of £1,658 per patient. Most (n = 50, 86%) remained well without recurrence at six-month follow-up.ConclusionsIn this case series, hypnotherapy was associated with rapid and sustained recovery of symptoms. A prospective randomized controlled study is required to confirm the findings and establish generalizability of the results.

Neurocognitive improvement after angioplasty in patients with chronic middle cerebral artery stenosis and cerebral ischemia.

The use of middle cerebral artery (MCA) angioplasty compared with drug therapy has been controversial. Few studies have reported the correlations between cognitive function improvement and MCA angioplasty. This study aimed to explore neurocognitive function after angioplasty in patients with middle cerebral artery stenosis (MCAS) and objective cerebral ischemia. We identified 14 patients diagnosed with MCAS aged 45-65 years. Neurocognitive function evaluation was performed by 2 independent clinical psychologists using the Mini-Mental State Examination (MMSE), Montreal cognitive assessment scale (MoCA), and Multi-Dimensional Psychology. All patients received general anesthesia, underwent diagnostic cerebral angiography (DSA) via the femoral route and angioplasty, and then were sent to the neurologic intensive care unit (NICU) for overnight hemodynamic and neurologic monitoring. Aspirin and clopidogrel treatments were continued for 3 months after successful intervention. Complete neurologic examinations, including assessment with the National Institutes of Health Stroke (NIHSS), and modulate RANK score (MRS) were conducted by 2 independent neurologists. The patients received a family follow-up at 1 week, 1 month, and 3 months after the interventional procedure. Neurologic sequelae, intracranial hemorrhages, and deaths were recorded as an endpoint. Follow-up clinical and imageological examinations were scheduled at 6 months after the intervention. Follow-up brain computed tomography (CT) perfusion or magnetic resonance angiography (MRA) perfusion scans performed by 2 imageological scanners were scheduled 6 months after the procedure. Angioplasty technical success was achieved in 14 parents (100%). We found that 10 patients did not have recurrent MCAS in the angioplasty site and had significant improvements in the associated brain perfusion situation and cognitive founction as compared before and after angioplasty. Also, 4 patients had evident restenosis in the angioplasty site. In the nonstenosis group, we found significant improvements in the MMSE, 3-dimensional (3D) mental rotation, simple calculation, and spatial working memory. In the recurrent stenosis group, we found no statistically significant changes in cognitive function compared with the baseline and after a 6-month follow up. There were high correlations between the changes in perfusion and the changes in word and picture memory. There was a significant correlation between the change in perfusion with MMSE (-0.522), spatial working memory (0.655), and Raven's progressive matrices test (0.637); a moderate correlation with 3D rotation (0.413), and simple calculation (-0.359); and weak correlation with visual tracking (0.026) and MoCA (0.279). Angioplasty surgery significantly improves neurocognitive function in patients with middle cerebral artery stenosis (MCAS) and objective cerebral ischemia.

The Prognostic Value of Quantitative EEG in Patients Undergoing Mechanical Thrombectomy for Acute Ischemic Stroke.

Previous work has shown that quantitative EEG measures correlate with the severity of ischemic stroke. This has not been systematically validated in patients with acute ischemic stroke who have undergone mechanical thrombectomy. Data were collected from 73 patients who underwent mechanical thrombectomy and had a standard head set EEG performed during their hospital admission. For each patient, the global delta-alpha ratio (DAR) and its difference between the two hemispheres were calculated. Associations between the global and interhemispheric DAR difference with the patients' National Institutes of Health Stroke and Modified Rankin Scale scores at discharge and 3 months after thrombectomy were assessed. The interhemispheric DAR difference correlated with the National Institutes of Health Stroke scores at discharge (Spearman R = 0.41, P = 0.0008), National Institutes of Health Stroke scores at 3 months (Spearman R = 0.60, P = 0.02) and Modified Rankin Scale scores at 3 months (Spearman R = 0.27, P = 0.01). In contrast, the global DAR did not correlate significantly with any of these clinical outcomes when evaluated as continuous variables. In a multivariate logistic regression model, both the interhemispheric DAR difference (β = 0.25, P = 0.03) and the infarct volume (β = 0.02, P = 0.03) were independently predictive of good versus poor functional outcome (Modified Rankin Scale score ≤2 vs. >2) at 3 months. The quantitative EEG measure of interhemispheric slow relative to fast frequencies power asymmetry correlated with the discharge and 3-month National Institutes of Health Stroke and Modified Rankin Scale scores and provided added value to infarct volume in predicting functional outcome at 3 months. These data support the prognostic value of quantitative EEG in ischemic stroke patients who have undergone mechanical thrombectomy.

Neuro vascular injury profile in CVA patients: A study on correlation between hematological indices and severity score in acute ischemic stroke

Acute ischemic stroke results from sudden loss of blood circulation to an area of cerebral hemispheres leading to irreversible brain injury and neurological deficits persisting for more than 24 hours or until death. It accounts for 80-87% of all strokes. In this study, we aim to find the association between various hematological indices such as Mean platelet Volume (MPV), Platelet distributionWidth (PDW), Neutrophil to Lymphocyte Ratio (NLR), Platelet to Lymphocyte ratio (PLR) and National Institute of Health Stroke Scale (NIHSS). Materials and Methods: It was a prospective study done at Department of Neurology at Meenakshi Medical College Hospital and Research Institute, Kancheepuram, Tamil Nadu in which 100 patients of Acute Ischemic stroke were divided into two groups basing on NIHSS score. Proper Exclusion criteria were carried out and the patients’ blood samples were taken. Various Hematological indices were measured and statistical analysis was done using SPSS Software. Results: There is positive correlation between NLR, PLR and NIHSS score. It is statistically significant association. But there is no statistical significance between Platelet indices and NIHSS score. Conclusion: Being Low cost and easy to measure nature of NLR and PLR, these indices can be used in the prediction of the prognosis in the Acute Ischemic Stroke patients. Keywords: Mean platelet Volume (MPV), Platelet distribution Width (PDW), Neutrophil to Lymphocyte Ratio (NLR), Platelet to Lymphocyte ratio (PLR), National Institute of Health Stroke, Scale (NIHSS).

Impact of Emergency Department Crowding on Delays in Acute Stroke Care.

IntroductionDelays in identification and treatment of acute stroke contribute to significant morbidity and mortality. Multiple clinical factors have been associated with delays in acute stroke care. We aimed to determine the relationship between emergency department (ED) crowding and the delivery of timely emergency stroke care.MethodsWe used prospectively collected data from our institutional Get with the Guidelines-Stroke registry to identify consecutive acute ischemic stroke patients presenting to our urban academic ED from July 2016–August 2018. We used capacity logs to determine the degree of ED crowding at the time of patients’ presentation and classified them as ordinal variables (normal, high, and severe capacity constraints). Outcomes of interest were door-to-imaging time (DIT) among patients potentially eligible for alteplase or endovascular therapy on presentation, door-to-needle time (DTN) for alteplase delivery, and door-to-groin puncture (DTP) times for endovascular therapy. Bivariate comparisons were made using t-tests, chi-square, and Wilcoxon rank-sum tests as appropriate. We used regression models to examine the relationship after accounting for patient demographics, transfer status, arrival mode, and initial stroke severity by the National Institutes of Health Stroke Scale.ResultsOf the 1379 patients with ischemic stroke presenting during the study period, 1081 (78%) presented at times of normal capacity, 203 (15%) during high ED crowding, and 94 (7%) during severe crowding. Median DIT was 26 minutes (interquartile range [IQR] 17–52); DTN time was 43 minutes (IQR 31–59); and median DTP was 58.5 minutes (IQR 56.5–100). Treatment times were not significantly different during periods of higher ED utilization in bivariate or in multivariable testing.ConclusionIn our single institution analysis, we found no significant delays in stroke care delivery associated with increased ED crowding. This finding suggests that robust processes of care may enable continued high-quality acute care delivery, even during times with an increased capacity burden.
