Custo Direto do Tratamento do Acidente Vascular Cerebral Isquêmico na Perspectiva de um Hospital Público Terciário (Direct Cost of Treating Ischemic Stroke From the Perspective of a Tertiary Public Hospital).

OBJECTIVES: To measure the direct cost of treating acute ischemic stroke (IS) from the perspective of a public hospital in Brazil (HCFMB) and compare it with the reimbursement by the Unified Health System (SUS), through the Procedure Table Management System, Medicines, Orthoses/Prostheses and Special Materials of the Unified Health System (SIGTAP). METHODS: We performed a micro-costing study; four scenarios were evaluated: standard (1); alteplase (2); alteplase and mechanical thrombectomy (3); mechanical thrombectomy (4). Based on the number of patients hospitalized for ischemic stroke in 2019, hospital cost, and SUS billing were calculated for each scenario. Hospital costs were adjusted for inflation using CCEMG-EPPI-Centre Cost Converter. RESULTS: In 2019, 258 patients were hospitalized due to IS, 89.5% in scenario 1, 8% in scenario 2, 1.5% in scenario 3, 1% in scenario 4. From the hospital's perspective, the cost per patient was estimated at R$7780.13, R$15 741.23, R$28 988.49, R$25 739.79, for scenarios 1, 2, 3 and 4, respectively. The reimbursement by SIGTAP was estimated at R$3079.87, R$5417.21, R$10 901.92, R$10 286.28, respectively. If thrombectomy had been included in the SIGTAP, the last two values would be R$25 393.34 and R$24 248.89. CONCLUSIONS: The hospital cost of treating acute IS in 2019 was estimated at R$2 295 209, the SUS reimbursement at R$889 391.54. With the inclusion of thrombectomy at SIGTAP, this reimbursement would be R$975 282.44, and the loss in the cost of HCFMB per patient in relation to reimbursement by the SUS is greater in scenarios without this procedure.

Are we missing an opportunity? Prehospital delay in patients with acute ischemic stroke and known atrial fibrillation.

INTRODUCTION AND OBJECTIVES: The follow-up of patients with atrial fibrillation (AF) presents an opportunity to alert patients and their families on how to recognize and act in the event of stroke. Our aim was to compare stroke recognition-to-door time and prehospital stroke code activation in patients with known AF (KAF) and AF detected after stroke (AFDAS). METHODS: We performed a retrospective cohort study of consecutive patients receiving acute recanalization treatment for acute ischemic stroke between January 2016 and August 2022, with AF as a potential stroke cause. Patients were divided into KAF and AFDAS, and stroke recognition-to-door time and prehospital stroke code activation were compared. In the KAF subgroup, we assessed whether the use of preadmission anticoagulation was associated with the studied prehospital parameters. RESULTS: We included 438 patients, 290 female (66.2%), mean age 79.3±9.4 years. In total, 238 patients had KAF (54.3%) and 200 (45.7%) had AFDAS. Of those with KAF, 114 (48.1%) were pretreated with anticoagulation. Patients with KAF and AFDAS had no differences in stroke recognition-to-door time (74.0 [55.0-101.0] vs. 78.0 [60.0-112.0] min; p=0.097) or prehospital stroke code activation [148 (64.6%) vs. 128 (65.3%); p=0.965]. In the KAF subgroup, preadmission anticoagulation did not influence stroke recognition-to-door time or mode of hospital admission. CONCLUSION: Stroke recognition-to-door time and prehospital stroke code activation were similar between patients with known or newly diagnosed AF. Preadmission anticoagulation treatment also did not affect the studied parameters. Our findings highlight a missed opportunity to promote stroke knowledge in patients followed due to AF.

Three-dimensional transesophageal echocardiographic evaluation of aortic plaque after cerebrovascular event.

INTRODUCTION AND OBJECTIVES: Transesophageal echocardiography (TEE) is crucial in order to assess aortic anatomy after stroke. Although routinely used to assess cardiovascular anatomy and function, three-dimensional echocardiography (3D TEE) is less used for aortic evaluation. We thus sought to assess prospectively whether additional information on aortic plaque morphology could be obtained with 3D TEE after an ischemic stroke. METHODS: Patients within one week of a stroke (confirmed by brain computed tomography/magnetic resonance) underwent TEE and 3D findings were compared with two-dimensional (2D) (aorta plaque number, dimensions, area and the presence of debris and ulcerations). Patients were followed for two years for death or a new stroke. RESULTS: We assessed 78 patients, 43 (55%) male, aged 62±14 years old, 92% in sinus rhythm. Aortic atheroma was found mainly in the descending aorta (50%); plaque thickness was similar for 2D TEE (0.29±0.03 cm) and 3D TEE (0.29±0.04 cm), whereas plaque area was slightly increased for 3D measurements (0.24±0.02 cm2 versus 0.37±0.03 cm2 respectively, p<0.05), with a strong correlation found both for aortic plaque thickness (r=0.91) and area (r=0.80) measurements. While aortic debris were equally seen with both techniques, 3D TEE defines the presence of ulcerations (six ulcerations unseen with 2D TEE better, p=0.03). There were 11 events (six deaths and five new strokes) during follow-up, unrelated to plaque characteristics. CONCLUSION: To evaluate aortic plaque morphology, 3D TEE is superior to 2D TEE due to improved detection of ulcerated aortic plaque; this might provide additional information in patients after ischemic stroke.

A new era in patent foramen ovale closure - a percutaneous suture-based 'deviceless' technique (NobleStitch®): Experience of a Portuguese center.

INTRODUCTION: In patients with cryptogenic stroke, one of the most frequently found abnormalities is patent foramen ovale (PFO). Percutaneous 'deviceless' systems based on surgical suture-mediated PFO closure have recently been introduced and show a favorable efficacy and safety profile with clear advantages. OBJECTIVES: To present procedural details of the technique and baseline characteristics of patients who underwent the procedure in our center. METHODS: A single-center prospective observational registry was established between February 2020 and February 2021, to assess the safety, efficacy and possible advantages of a novel percutaneous PFO closure system (NobleStitch® EL). Patient and PFO characteristics as well as technical features were collected for analysis. RESULTS: Twenty-three patients were considered suitable for this technique after transesophageal echocardiography. Their mean age was 51 years and 69.5% were women. Most patients (91.3%) had a history of cryptogenic stroke. PFO closure with the NobleStitch® system was successfully performed in all patients. All procedures were performed under local anesthesia and fluoroscopic monitoring. The mean duration of the procedure was 52 min and median contrast dose used was 187 ml. Median radiation dose absorbed per patient was 61.5 Gy cm2. All patients were discharged asymptomatic 24 hours after the procedure with no peri- or postprocedural complications recorded. CONCLUSION: Suture-mediated PFO closure represents a valid and safe alternative to traditional umbrella-like devices, and is feasible in the majority of PFO anatomies. Follow-up information, results of larger series and clinical trials may possibly validate this technique as the first choice for PFO closure.

Optimizing prognosis in atrial fibrillation: A call to action in Portugal.

Atrial fibrillation (AF), the most common arrhythmia in the adult population worldwide, represents a significant burden in terms of cardiovascular mortality and morbidity and has repercussions on health economics. Oral anticoagulation (OAC) is key to stroke prevention in AF and, in recent years, results from landmark clinical trials of non-vitamin K oral anticoagulants (NOAC) have triggered a paradigm shift in thrombocardiology. Despite these advances, there is still a significant residual vascular risk associated with silent AF, bleeding, premature sudden death and heart failure. The authors review AF epidemiologic data, the importance of new tools for early AF detection, the current role of catheter ablation for rhythm control in AF, the state-of-the-art in periprocedural OAC, the optimal management of major bleeding, the causes of residual premature death and future strategies for improvements in AF prognosis.

Increased serum interleukin-6 level as a predictive biomarker for atrial fibrillation: A systematic review and meta-analysis.

BACKGROUND: Atrial fibrillation (AF) is related to a higher risk of thromboembolic events and mortality. Some studies have demonstrated that the inflammatory biomarker interleukin-6 (IL-6) is associated with a higher risk of higher thrombosis in AF patients, but the real effect of IL-6 remains a controversy. METHODS: We conducted a systematic review and meta-analysis to investigate the association between IL-6 and thromboembolic events, as well as bleeding events, acute coronary syndrome (ACS) events and all-cause mortality in AF. RESULTS: A total of five studies involving 22 928 patients met our inclusion criteria for the systematic review. The higher level of IL-6 in AF patients is related to long-term thromboembolic events including stroke (RR 1.44, CI 95% 1.09-1.90, p=0.01). IL-6 meant a higher risk of long-term bleeding risk (RR 1.36, CI 95% 1.06-1.74, p=0.02), ACS risk (RR 1.81, CI 95% 1.43-2.30, p<0.001) and all-cause mortality (RR 2.35, CI 95% 2.09-2.65, p<0.001). CONCLUSION: A higher level of IL-6 may predict a greater number of long-term thromboembolic events and bleeding events, ACS events and mortality in AF patients. Further studies such as the cut-off point of IL-6 need to be conducted in the future.

[Cerebellar infarct following orchidopexy under spinal anesthesia]. / Infarto cerebelar após orquidopexia sob raquianestesia.

The report describes a case of peri-operative stroke that presented as diplopia and gait difficulty on 2nd post-operative day after routine orchidopexy under spinal anesthesia in an otherwise healthy young boy. Magnetic resonance imaging of the brain revealed acute infarct in bilateral cerebellar hemispheres, left half of medulla and left thalamus. A diagnosis of acute stroke (infarct) was made and patient was started on oral aspirin 75mg.day-1, following which his vision started improving after 2 weeks. Possible mechanisms of development of stroke in the peri-operative period are discussed, but, even after extensive investigations, the etiology of infarct may be difficult to determine. Acute infarct after elective non-cardiac, non-neurological surgery is rare; it may not be possible to identify the etiology in all cases. Clinicians must have a high index of suspicion to diagnose such unexpected complications even after routine surgical procedures in order to decrease the morbidity and long term sequelae.

Homocysteine serum levels in patients with ruptured and unruptured intracranial aneurysms: a case-control study / Homocisteína sérica em pacientes com aneurismas rotos e não rotos: um estudo caso-controle

Abstract Background There is very few data regarding homocysteine's influence on the formation and rupture of intracranial aneurysms. Objective To compare homocysteine levels between patients with ruptured and unruptured intracranial aneurysms, and to evaluate possible influences of this molecule on vasospasm and functional outcomes. Methods This is a retrospective, case-control study. We evaluated homocysteinemia differences between patients with ruptured and unruptured aneurysms; and the association of homocysteine levels with vasospasm and functional outcomes. Logistic regressions were performed. Results A total of 348 participants were included: 114 (32.8%) with previous aneurysm rupture and 234 (67.2%) with unruptured aneurysms. Median homocysteine was 10.75μmol/L (IQR = 4.59) in patients with ruptured aneurysms and 11.5μmol/L (IQR = 5.84) in patients with unruptured aneurysms. No significant association was detected between homocysteine levels and rupture status (OR = 0.99, 95% CI = 0.96-1.04). Neither mild (>15μmol/L; OR = 1.25, 95% CI 0.32-4.12) nor moderate (>30μmol/L; OR = 1.0, 95% CI = 0.54-1.81) hyperhomocysteinemia demonstrated significant correlations with ruptured aneurysms. Neither univariate (OR = 0.86; 95% CI 0.71-1.0) nor multivariable age-adjusted (OR = 0.91; 95% CI = 0.75-1.05) models evidenced an association between homocysteine levels and vasospasm. Homocysteinemia did not influence excellent functional outcomes at 6 months (mRS≤1) (OR = 1.04; 95% CI = 0.94-1.16). Conclusion There were no differences regarding homocysteinemia between patients with ruptured and unruptured intracranial aneurysms. In patients with ruptured aneurysms, homocysteinemia was not associated with vasospasm or functional outcomes.

Nem a hiperhomocisteinemia leve (>15μmol/L; OR = 1,25, 95% CI = 0,32-4,12) nem a moderada (>30μmol/L; OR = 1,0, 95% CI = 0,54-1,81) mostraram correlações significativas com aneurismas rotos. Modelos univariados (OR = 0,86; 95% CI = 0,71-1,0) e multivariados ajustados por idade (OR = 0,91; 95% CI = 0,75-1,05) não evidenciaram associação entre homocisteína e vasoespasmo. A homocisteinemia não influenciou resultados funcionais excelentes em seis meses (mRS ≤ 1) (OR = 1,04; 95% CI = 0,94-1,16). Conclusão Não houve diferenças em relação à homocisteinemia entre pacientes com aneurismas intracranianos rotos e não rotos. Em pacientes com aneurismas rotos, a homocisteinemia não foi associada ao vasoespasmo ou resultados funcionais.

Reliability and validity of remote Life Space Assessment: LSA in persons with chronic stroke / Confiabilidade e validade da escala Life Space Assessment aplicada remotamente: LSA em pacientes com AVC crônico

Abstract Background StepWatch Activity Monitor (SAM) is used to measure the mobility of chronic hemiparetic patients and the Life Space Assessment (LSA) scale was developed to assess the displacement of hemiparetic patients in different contexts through self-reporting. Studies that apply the LSA remotely and correlate it with the number of steps measured by the SAM were not found. Objective To evaluate the measurement properties of the LSA applied remotely and to evaluate the correlation between the LSA scale score and the number of steps measured by the SAM in post-stroke chronic hemiparetic patients. Methods Nineteen patients participated in the study. The LSA scale was applied remotely and later, face to face. The SAM measured the steps taken by the participants over a period of three consecutive days. The correlation between the LSA and the SAM was performed using Pearson's correlation. The measurement properties calculated of remote LSA were the intraclass correlation coefficient (ICC), Cronbrach's alpha, standard error of measurement (SEM), and smallest real difference (SRD). Results The reproducibility of the LSA scale between remote and face-to-face applications was considered excellent with ICC = 0.85 (IC 95% 0.62-0.94); SEM = 8.4; SRD = 23.2, and Cronbach's alpha = 0.85. The correlation between SAM and LSA was positive, considered moderate (r = 0.51) and significant (p = 0.025). Conclusion The LSA is a reproducible measure for post-stroke chronic hemiparetic patients even if applied remotely and can be used as a remote measurement for mobility in a real-world environment for people with chronic hemiparesis after stroke.

Resumo Antecedentes O StepWatch Activity Monitor (SAM) é utilizado para medir a mobilidade de pacientes hemiparéticos crônicos e a escala Life Space Assessment (LSA) avalia o deslocamento de pacientes hemiparéticos em diferentes contextos por meio de autorrelato. Não foram encontrados estudos que tenham aplicado a LSA remotamente nem que a correlacionam com o número de passos mensurados pelo SAM. Objetivo Avaliar as propriedades de medida da LSA aplicada remotamente e avaliar a correlação entre o escore da escala LSA e o número de passos mensurados pelo SAM em pacientes com hemiparesia crônica pós-AVC. Métodos Dezenove participantes responderam a LSA remotamente e, posteriormente, presencialmente. O SAM mediu os passos dados pelos participantes durante um período de três dias consecutivos. A correlação entre a LSA e o SAM foi realizada por meio da correlação de Pearson. As propriedades de medida calculadas da LSA aplicada remotamente foram o coeficiente de correlação intraclasse (ICC), alfa de Cronbrach, erro do padrão de medida (SEM) e menor diferença real (SRD). Resultados A reprodutibilidade da escala LSA entre as aplicações remotas e presenciais foi considerada excelente com ICC = 0,85 (IC 95% 0,62-0,94); SEM = 8,4; SRD = 23,2 e alfa de Cronbrach = 0,85. A correlação entre SAM e a LSA foi positiva, considerada moderada (r = 0,51) e significativa (p= 0,025). Conclusão A LSA é uma medida reprodutível para pacientes hemiparéticos crônicos pós-AVC mesmo se aplicada remotamente e pode ser usada como uma medida remota de mobilidade em ambiente real para pessoas com hemiparesia crônica após AVC.

Ischemic stroke in patients previously anticoagulated for non-valvular atrial fibrillation: Why does it happen? / Acidente vascular cerebral isquémico em doentes previamente anticoagulados por fibrilhação auricular não valvular: por que acontece?

INTRODUCTION: Oral anticoagulants have proved to be highly effective in preventing atrial fibrillation (AF)-related strokes. The occurrence of stroke despite oral anticoagulation is unexpected and little is known about the mechanisms responsible. The aim of this study was to assess possible mechanisms for stroke occurrence, such as poor treatment adherence and inappropriate dosage, in patients chronically anticoagulated for AF. METHODS: We performed a prospective observational study of 60 consecutive patients with non-valvular AF, chronically medicated with an oral anticoagulant and admitted due to ischemic stroke. Treatment adherence was assessed through the Brief Medication Questionnaire (BMQ) and the Medição da Adesão ao Tratamento (MAT) scales. Patient characteristics, stroke etiology, and appropriacy of anticoagulant dosage were also assessed. RESULTS: Patients' mean age was 78.6±8.0 years, and 51.7% were male. Overall, the proportion of patients with good adherence to anticoagulants was 63.3%. Adherent patients were more frequently illiterate (26.3% vs. 4.5%, p=0.012). The proportion of patients under vitamin K antagonists (VKAs) with good treatment adherence was significantly higher than that of patients under novel oral anticoagulants (NOACs) (83.3% vs. 54.8%, respectively, for BMQ, p=0.035). However, 91.7% of patients under VKAs presented an admission INR <2. Subtherapeutic prescriptions were found in 43% of patients under NOACs. CONCLUSION: In the majority of patients, stroke occurrence despite chronic anticoagulation appears to be explained by subtherapeutic dosage, poor treatment adherence or non-cardioembolic etiology, and not by inefficacy of the anticoagulants.

A Brazilian series utilizing the SMASH-U system for etiologic classification of intracerebral hemorrhage / Classificação etiológica de pacientes admitidos com hemorragia intracerebral utilizando a escala SMASH-U: uma série brasileira

Abstract Background Understanding the causes of intracerebral hemorrhage (ICH) is crucial for effective treatment and preventing recurrences. The SMASH-U scale is a suggested method for classifying and predicting the outcomes of ICH. Objective To describe the SMASH-U classification and outcomes by etiology in patients admitted to a comprehensive stroke center in São Paulo, Brazil. Methods A retrospective analysis was conducted on patients admitted to the hospital or outpatient clinic between April 2015 and January 2018. Two stroke neurologists evaluated the SMASH-U classification, and patients with incomplete medical records were excluded. Results Out of the 2000 patients with a stroke diagnosis evaluated, 140 were included in the final analysis. The mean age was 57.9 (± 15.5) years, and 54.3% were male. Hypertension was the most frequent etiology, accounting for 41.4% of cases, followed by amyloid angiopathy (18.5%) and structural lesions (14.1%). Structural lesions were more common among women and patients under 45 years old. Favorable outcomes were observed in 61% of patients with structural lesions, compared to 10% of patients with medication-related etiologies. Conclusion This study provides important evidence regarding the etiological classification of Brazilian patients with ICH. Hypertension and amyloid angiopathy were the most frequent causes, while structural lesions and systemic diseases were more common in younger patients.

Resultados favoráveis foram observados em 61% dos pacientes com lesões estruturais, em comparação com 10% dos pacientes com etiologias relacionadas a medicamentos. Conclusão Este estudo fornece evidências importantes sobre a classificação etiológica de pacientes brasileiros com HIC. A hipertensão e a angiopatia amiloide foram as causas mais frequentes, enquanto lesões estruturais e doenças sistêmicas foram mais comuns em pacientes mais jovens.

Comparación entre tenecteplase y alteplase en la trombolisis intravenosa del ataque cerebrovascular isquémico

Introducción: la trombolisis intravenosa es parte fundamental del tratamiento agudo de los pacientes que sufren un ataque cerebrovascular (ACV) isquémico. Existe un interés creciente en la utilización de tenecteplase como alternativa trombolítica a alteplase. El objetivo del presente trabajo es comparar la efectividad clínica de tenecteplase respecto a alteplase en la trombolisis intravenosa del ACV isquémico. Método: estudio de cohorte, bispectivo y unicéntrico, de todos los pacientes ingresados con ACV isquémico y que recibieron trombolíticos intravenosos, desde 2019 a 2022. Se compararon prospectivamente los pacientes tratados con tenecteplase con aquellos tratados con alteplase como control histórico. Se realizó test de chi cuadrado o exacto de Fisher para la asociación de variables categóricas y prueba de Wilcoxon para la comparación de medianas. Se consideró significativo un valor p menor de 0,05. Resultados: se incluyeron 69 pacientes (33 recibieron alteplase y 36 tenecteplase). La mediana de la escala de NIHSS fue de 11 (RIC 8-18) y del tiempo inicio de síntomas-aguja de 160 minutos (RIC 120-208). No se hallaron diferencias estadísticamente significatvas entre los puntajes de las escalas de coma de Glasgow y NIHSS al egreso hospitalario, así como en la escala de Rankin modificada (mRS) 0-2 y mortalidad a los seis meses, entre los dos grupos de pacientes. Tampoco hubo diferencias en las complicaciones hemorrágicas intracraneanas entre ambos grupos (13,9% para tenecteplase y 12,1% para alteplase). Conclusiones: se presenta el primer estudio acerca del tema en nuestro medio. En concordancia con los recientes ensayos internacionales, el presente trabajo no mostró diferencias significativas en los resultados clínicos de los pacientes tratados con tenecteplase o alteplase. El tenecteplase podría ser una alternativa razonable a alteplase como terapia trombolítica en el ACV isquémico, con una buena relación costo-beneficio y forma de implementación más sencilla. Se necesitan estudios aleatorizados y con un mayor número de pacientes.

Introduction: intravenous thrombolysis is a key part of the acute treatment of patients with ischemic stroke. There is a growing interest in the use of tenecteplase as a thrombolytic alternative to alteplase. The aim of this study is to compare the clinical effectiveness of tenecteplase versus alteplase in intravenous thrombolysis for ischemic stroke. Method: a single-center, bispective cohort study of all patients admitted with ischemic stroke who received intravenous thrombolytics from 2019 to 2022. Patients treated with tenecteplase were prospectively compared with those treated with alteplase as a historical control. Chi-square or Fisher's exact test was used for the association of categorical variables, and the Wilcoxon test was used for median comparison A p-value of less than 0.05 was considered significant. Results: a total of 69 patients were included in the study (33 received alteplase and 36 received tenecteplase). The median NIHSS scale score was 11 (IQR 8-18), and the median time from symptom onset to needle was 160 minutes (IQR 120-208). No statistically significant differences were found between Glasgow Coma Scale and NIHSS scores at hospital discharge, as well as in modified Rankin Scale (mRS) 0-2 and mortality at 6 months, between the two groups of patients. There were also no differences in intracranial hemorrhagic complications between both groups (13.9% for tenecteplase and 12.1% for alteplase). Conclusions: This is the first study on the topic in our setting. In line with recent international trials, our study did not show significant differences in clinical outcomes of patients treated with tenecteplase or alteplase. Tenecteplase could be a reasonable alternative to alteplase as thrombolytic therapy in ischemic stroke, with a good cost-benefit ratio and simpler implementation. Randomized studies with a larger number of patients are needed.

Métodos: estudo de coorte, bispectivo, em um único centro, de todos os pacientes admitidos com AVC isquêmico que receberam trombolíticos intravenosos de 2019 a 2022. Os pacientes tratados com tenecteplase foram comparados prospectivamente com aqueles tratados com alteplase como um controle histórico. O teste de qui-quadrado ou exato de Fisher foi realizado para a associação de variáveis categóricas e o teste de Wilcoxon para a comparação de medianas. Um valor de p inferior a 0,05 foi considerado significativo. Resultados: Foram incluídos 69 pacientes (33 receberam alteplase e 36 tenecteplase). A mediana do escore da escala NHISS foi de 11 (RIC 8-18) e a mediana do tempo de início dos sintomas foi de 160 minutos (RIC 120-208). Não foram encontradas diferenças estatisticamente significativas entre os escores de coma de Glasgow e NIHSS na alta hospitalar, bem como na Escala de Rankin modificada (MRS) 0-2 e na mortalidade em 6 meses, entre os dois grupos de pacientes. Também não houve diferenças nas complicações hemorrágicas intracranianas entre os dois grupos (13,9% para tenecteplase e 12,1% para alteplase). Conclusões: Este é o primeiro estudo sobre o assunto em nosso meio. De acordo com estudos internacionais recentes, nosso estudo não mostrou diferenças significativas nos resultados clínicos em pacientes tratados com tenecteplase ou alteplase. A tenecteplase poderia ser uma alternativa razoável à alteplase como terapia trombolítica no AVC isquêmico, com uma boa relação custo-benefício e implementação mais fácil. São necessários estudos randomizados com um número maior de pacientes.

Improving walking via real-time visual feedback after stroke in treadmill training (RE-VISIT): a protocol for randomized controlled trial / Melhorando a caminhada por meio de feedback visual em tempo real após acidente vascular cerebral em treinamento em esteira (RE-VISIT): um protocolo para ensaio clínico randomizado

BACKGROUND: After a stroke, most patients often suffer reduced walking ability and balance. Restoring walking ability and improving balance are major goals of stroke rehabilitation. Treadmills are often used in clinical setups to achieve these goals. Adding dimensions to the visual feedback in addition to the mirror for real-time frontal view is proven to enhance the gait. It is, therefore, important to design additional real-time visual feedback in treadmill training, in particular for the sagittal view involved side. OBJECTIVE: The objective of this study is to test if the real-time sagittal visual feedback during treadmill training is superior to the conventional mirror feedback treadmill training program of equivalent intensity in improving walking speed and balance after stroke. METHODS/DESIGN: The RE-VISIT trial (Real-time Visual feedback after Stroke in Treadmill training) is registered in the Clinical Trial Registry of India (CTRI/2023/10/058299). In this two-arm randomized control trial, which will be a single-blinded study, 42 eligible stroke survivors undergoing rehabilitation will be randomly allocated (1:1 ratio) to either real-time visual sagittal feedback along with front mirror (experimental) group or only front mirror treadmill training (control) group, all the participants will receive 15 sessions of treadmill training for up to 15 min at a safe self-selected speed over 5-6 weeks. The RE-VISIT (experimental) group will receive real-time, visual sagittal view feedback of the involved lower limb trajectory along with the routine front mirror view during treadmill training and will be asked to modify their gait pattern. The control group will receive treadmill walking training only with the routine front mirror view feedback. Clinical and gait assessments will be conducted at the baseline, immediately following the final session of training, and at the 9th week during follow-up. The outcome measures of interest are walking speed (primary) and balance (secondary), which will be measured prior to baseline, post 15 sessions of training, and at the 9th week following training. DISCUSSION: This REVISIT trial will provide insight and contribute to the existing innovation and modifications of incorporating realtime visual feedback during treadmill training in post-stroke gait rehabilitation. The findings will help the better designing of a gait rehabilitation program with a treadmill for post-stroke subjects to improve walking speed, and balance for those who have greater difficulties in community ambulation. We anticipate that those in the REVISIT training will demonstrate improved walking ability.

CONTEXTO: Após o acidente vascular cerebral, a maioria dos pacientes frequentemente sofre redução da capacidade de caminhar e do equilíbrio. Restaurar a capacidade de caminhar e melhorar o equilíbrio são os principais objetivos da reabilitação do AVC. As esteiras são frequentemente usadas em ambientes clínicos para atingir esses objetivos. Está comprovado que adicionar dimensões ao feedback visual, além do espelho para visão frontal em tempo real, melhora a marcha. É, portanto, importante projetar feedbacks visuais adicionais em tempo real no treinamento em esteira, em particular para o lado envolvido na visão sagital. OBJETIVO: O objetivo deste estudo é testar se o feedback visual sagital em tempo real durante o treinamento em esteira é superior ao programa de treinamento em esteira com feedback de espelho convencional de intensidade equivalente na melhoria da velocidade de caminhada e equilíbrio após acidente vascular cerebral. MÉTODOS/ DESENHO: O ensaio RE-VISIT (feedback visual em tempo real após acidente vascular cerebral no treinamento em esteira) está registrado no Registro de Ensaios Clínicos da Índia (CTRI/2023/10/058299). Neste ensaio de controle randomizado de dois braços, que será um estudo cego, 42 sobreviventes de AVC elegíveis em reabilitação serão alocados aleatoriamente (proporção de 1:1) para feedback sagital visual em tempo real junto com grupo de espelho frontal (experimental) ou apenas Grupo de treinamento em esteira com espelho frontal (controle), todos os participantes receberão 15 sessões de treinamento em esteira por até 15 minutos em uma velocidade segura e autosselecionada durante 5-6 semanas. O grupo RE-VISIT (experimental) receberá feedback visual em tempo real da visão sagital da trajetória dos membros inferiores envolvidos, juntamente com a visão rotineira do espelho frontal durante o treinamento em esteira e será solicitado a modificar seu padrão de marcha. O grupo de controle receberá treinamento de caminhada em esteira apenas com o feedback rotineiro da visão do espelho frontal. Avaliações clínicas e de marcha serão realizadas no início do estudo, imediatamente após a sessão final de treinamento e na 9ª semana durante o acompanhamento. As medidas de resultados de interesse são a velocidade de caminhada (primária) e o equilíbrio (secundário), que serão medidos antes da linha de base, após a 15ª sessão de treinamento e na 9ª semana após o treinamento. DISCUSSÃO: este ensaio REVISIT fornecerá insights e contribuirá para a inovação e modificações existentes na incorporação de feedbacks visuais em tempo real durante o treinamento em esteira na reabilitação da marcha pós-AVC. As descobertas ajudarão no melhor desenho de um programa de reabilitação da marcha com esteira para indivíduos pós-AVC para melhorar a velocidade de caminhada e o equilíbrio para aqueles que têm maiores dificuldades na deambulação comunitária. Prevemos que aqueles no treinamento REVISIT demonstrarão melhor capacidade de caminhada.

Efficiency of pulsed electromagnetic field and neuromuscular electrical stimulation on painful shoulder following stroke / Eficiência do campo eletromagnético pulsado e da estimulação elétrica neuromuscular em ombro doloroso após acidente vascular cerebral

INTRODUCTION: Shoulder pain after stroke, a complication with a prevalence of up to 16­84% usually occurs after 2­3 months and leads to patients withdrawing from rehabilitation programs, staying in the hospital longer, having less limb function and having a great negative impact on their quality of life. The aim of the present study was to determine the effect of PEMF and NMES in reducing shoulder pain in patients with stroke. MATERIAL AND METHODS: A prospective, randomized controlled trial included 51 patients with shoulder pain following stroke. The patients were randomly assigned to three groups (17 people in each group): Pulsed Electromagnetic Field (PEMF), Neuromuscular Electrical Stimulation (NMES) and Control group. The outcome measures were Visual Analogue Scale (VAS), Modified Ashworth Scale (MAS) and Fugl Meyer Assessment­Upper Extremity (FMA-UE), Active and Passive Range of Motion (AROM/PROM) assessed at the baseline, six weeks into the intervention, and one week into the follow-up. RESULTS: VAS score for pain showed a mean change of 1.60, 1.60 and 4.94 in PEMF, NMES, and control respectively after 20 sessions. It showed pain was significantly improved in all the groups (p<0.001), but the effectiveness of the PEMF and NMES groups was superior to the control group. CONCLUSION: The current literature showed that PEMF & NMES are effective in improving post-stroke shoulder pain, spasticity, range of motion and motor function and a novel method for stroke patients undergoing rehabilitation.

INTRODUÇÃO: Dor no ombro após acidente vascular cerebral com prevalência de 16­84% geralmente ocorre após 2­3 meses e pode resultar na suspensão de programas de reabilitação, internações hospitalares mais longas e redução da função dos membros, prejudicando qualidade de vida dos pacientes com AVC. O objetivo do presente estudo foi determinar o efeito da PEMF e da EENM na redução da dor no ombro em pacientes com acidente vascular cerebral. MATERIAL E MÉTODOS: Um estudo prospectivo, randomizado e controlado incluiu 51 pacientes com dor no ombro pós-AVC. Os pacientes foram divididos aleatoriamente em três grupos (17 pessoas em cada grupo): grupo Campo Eletromagnético Pulsado (PEMF), grupo Estimulação Elétrica Neuromuscular (EENM) e grupo Controle. As medidas de resultados foram na Escala Visual Analógica (VAS), Escala de Ashworth Modificada (MAS) e Avaliação de Fugl Meyer ­ Extremidade Superior (FMA-UE), Amplitude de Movimento (AROM/PROM) foram avaliadas no início do estudo, após seis semanas de tratamento, e após um acompanhamento semanal. RESULTADOS: A pontuação VAS para dor mostrada uma alteração média de 1,60, 1,60 e 4,94 na PEMF, EENM e Controle, respectivamente, após 20 sessões. Mostrou melhora significativa entre os três grupos (p<0,001), mas a eficácia do grupo PEMF e EENM foi superior ao grupo Controle. CONCLUSÃO: O presente estudo mostrou que PEMF e EENM são eficazes na melhora da dor no ombro pós-AVC, espasticidade, amplitude de movimento e função motora e um novo método para pacientes com AVC em reabilitação. Nossas descobertas indicam que a eficácia da EENM é claramente superior à do PEMF na manutenção da analgesia a longo prazo.

Abstract Objective To assess the functional disability level and identify associated factors in people after Ischemic Cerebral Vascular Accident. Methods A prospective cohort, carried out in a reference hospital in neurology with 224 people with ischemic stroke. Data collection took place between March and October 2019. Participants were followed up during hospitalization, when sociodemographic and clinical variables were collected using specific instruments and contacted after 90 days, by telephone call, to apply the Modified Barthel Index. In the analysis, descriptive statistics and Pearson's chi-square test were applied. Statistical significance of 5% was adopted. Results Most had some degree of functional disability (58.5%), with 29.5% having moderate dependence and 29.0% having severe dependence. The variables being female (p=0.011), time of arrival at the reference hospital greater than or equal to 4.5 hours (p=0.017), previous stroke (p=0.031), not having undergone thrombolysis (p=0.023), having high blood pressure (p=0.032) and greater severity estimated by the National Institute of Health Stroke Scale (p=0.000) were associated with a higher disability level. Conclusion Moderate to severe dependence predominated. The severity of the event, previous event, hypertension, non-submission to thrombolysis, delay in arriving at the hospital and female gender were associated with a higher functional disability level.

Evaluation of the relationship between computed tomography angiography collateral scores and clinical outcome / Avaliação da relação entre escores colaterais da angiotomografia computadorizada e evolução clínica

Abstract Background The relationship between collateral circulation and prognosis after endovascular treatment in anterior circulation strokes has been reported in many studies. Objective In this study, we aimed to compare the predictive power of clinical outcome by comparing five different collateral scores that are frequently used. Methods Among the patients who underwent endovascular treatment in our clinic between November 2019 and December 2021, patients with premorbid mRS < 3, intracranial ICA and/or MCA M1 occlusion, and a pre-procedural multiphase CTA examination were included in the study. Demographic, technical, and duration information about the procedure, major events after the procedure, and clinical outcomes at 3 months were recorded. The mCTA, Tan, Maas, Miteff, and rLMC collateral scores of the patients were evaluated. Results Clinical outcome at 3 months were good in 37 of the 68 patients included in the study (mRS ≤ 2). Only the mCTA and rLMC collateral scores were statistically significantly higher in those with a good clinical outcome. Significant correlation with 3-month mRS was detected only in mCTA and rLMC scores. Although rLMC and mCTA collateral scores showed a statistically significant association with prognosis, they were not sufficient to be an independent predictor of prognosis. Conclusion mCTA and rLMC were found to have the highest predictive power of clinical outcome and the highest correlation with the 3-month clinical outcome. Our study suggests that it would be beneficial to develop a new scoring system over multiphase CTA, which combines regional and temporal evaluation, which are the strengths of both collateral scoring.

Resumo Antecedentes A relação entre circulação colateral e prognóstico após tratamento endovascular em acidentes vasculares cerebrais de circulação anterior tem sido relatada em muitos estudos. Objetivo Neste estudo, nosso objetivo foi comparar o poder preditivo do desfecho clínico comparando cinco escores colaterais diferentes que são frequentemente utilizados. Métodos Entre os pacientes submetidos a tratamento endovascular em nossa clínica entre novembro de 2019 e dezembro de 2021, foram incluídos no estudo pacientes com mRS pré-mórbido < 3, oclusão intracraniana de ICA e/ou MCA M1 e exame de CTA multifásico pré-procedimento. Foram registradas informações demográficas, técnicas e de duração sobre o procedimento, eventos importantes após o procedimento e resultados clínicos em três meses. Foram avaliados os escores colaterais mCTA, Tan, Maas, Miteff e rLMC dos pacientes. Resultados Os resultados clínicos aos três meses foram bons em 37 dos 68 pacientes incluídos no estudo (mRS ≤ 2). Apenas os escores colaterais mCTA e rLMC foram estatisticamente significativamente maiores naqueles com boa evolução clínica. Correlação significativa com mRS de três meses foi detectada apenas nos escores mCTA e rLMC. Embora os escores colaterais de rLMC e mCTA tenham mostrado uma associação estatisticamente significativa com o prognóstico, eles não foram suficientes para serem um preditor independente de prognóstico. Conclusão Verificou-se que mCTA e rLMC têm o maior poder preditivo do resultado clínico e a maior correlação com o resultado clínico de três meses. Nosso estudo sugere que seria benéfico desenvolver um novo sistema de pontuação em vez de CTA multifásico, que combinasse avaliação regional e temporal, que são os pontos fortes de ambas as pontuações colaterais.

Utilização da bandagem elástica funcional no tratamento fonoaudiológico da paralisia facial pós-AVC na fase aguda / Use of athletic tape in the speech-language-hearing treatment of post-stroke facial paralysis in the acute phase

RESUMO Objetivo Verificar a eficácia do uso da bandagem elástica funcional associada à terapia miofuncional no tratamento fonoaudiológico da paralisia facial pós-acidente vascular cerebral na fase aguda. Método Estudo clínico controlado randomizado com 88 pacientes com paralisia facial na fase aguda do acidente vascular cerebral. A amostra foi alocada em: Grupo 1: reabilitação com terapia miofuncional orofacial e utilização da bandagem elástica funcional nos músculos zigomáticos maior e menor paralisados; Grupo 2: reabilitação apenas com terapia miofuncional orofacial na face paralisada; Grupo 3: sem qualquer intervenção fonoaudiológica para paralisia facial. Na avaliação foram solicitados os movimentos de mímica facial e o grau do comprometimento foi determinado de acordo com a escala de House e Brackmann. A incompetência do movimento foi obtida a partir de medições da face com paquímetro digital. Após a avaliação, a intervenção foi realizada de acordo como determinado para os grupos 1 e 2. Os participantes dos três grupos foram reavaliados após 15 dias. A análise estatística utilizada foi das equações generalizadas. Resultados Os grupos foram homogêneos quanto à idade, medida de incapacidade e funcionalidade, gravidade do comprometimento neurológico e da paralisia facial pré-intervenção. O grupo 1 teve melhora significativa na medida canto externo do olho à comissura labial, com melhores resultados quando comparado aos grupos 2 e 3. Conclusão A bandagem elástica funcional associada a terapia miofuncional orofacial apresentou melhor resultado no tratamento da paralisia facial após acidente vascular cerebral no local onde foi aplicado.

ABSTRACT Purpose To verify the efficacy of using athletic tape associated with myofunctional therapy in the speech-language-hearing treatment of facial palsy after stroke in the acute phase. Method Randomized controlled clinical study with 88 patients with facial palsy in the acute phase of stroke. The sample was allocated in: Group 1: rehabilitation with orofacial myofunctional therapy and use of athletic tape on the paralyzed zygomaticus major and minor muscles; Group 2: rehabilitation alone with orofacial myofunctional therapy on the paralyzed face; Group 3: no speech-language-hearing intervention for facial paralysis. In the evaluation, facial expression movements were requested, and the degree of impairment was determined according to the House and Brackmann scale. Movement incompetence was obtained from measurements of the face with a digital caliper. After the evaluation, the intervention was carried out as determined for groups 1 and 2. The participants of the three groups were reassessed after 15 days. The statistical analysis used was the generalized equations. Results The groups were homogeneous in terms of age, measure of disability and functioning, severity of neurological impairment and pre-intervention facial paralysis. Group 1 had a significant improvement in the measure from the lateral canthus to the corner of the mouth, with better results than groups 2 and 3. Conclusion The athletic tape associated with orofacial myofunctional therapy had better results in the treatment of facial paralysis after stroke in the place where it was applied.

Physical therapy care to community-dwelling individuals with stroke in primary care setting in Brazil: a cross-sectional study / Asistencia de fisioterapia a personas con accidente cerebrovascular que viven en la comunidad en atención primaria en Brasil: un estudio transversal / Assistência fisioterapêutica a indivíduos com Acidente Vascular Encefálico residentes na comunidade na atenção básica no Brasil: um estudo transversal

ABSTRACT After hospital discharge, it is recommended that post-stroke individuals receive follow-up by a physical therapist throughout all the stages of recovery. Despite clinical recommendations, few studies have investigated physical therapy care to community-dwelling individuals with stroke. This study aimed to describe physical therapy care to community-dwelling individuals with stroke in primary care setting and identify clinical-functional and sociodemographic characteristics that determined physical therapy assistance. This is an exploratory cross-sectional study. Community-dwelling individuals with stroke who were assisted by the primary healthcare team from an important Brazilian metropolis were included. Their medical records were analyzed to identify the care provided by physical therapists. Individuals who received and did not receive physical therapy care were compared (α=0.05). Out of the 100 included individuals, 55% received assistance from the multidisciplinary primary healthcare team and 44% from physical therapists. Physical therapy approaches consisted mainly of general orientations (89%) and assessments (75%). Only 45% of the individuals who received physical therapy care were followed-up, and those who received this type of care had significantly more stroke events and higher levels of disability (p<0.001). It was observed that many individuals with various levels of disabilities have not received physical therapist assistance. Moreover, follow-up care and referrals were not frequent physical therapy approaches. Therefore, physical therapy care in primary care needs to be expanded to ensure that all individuals with some level of disability receive treatment. Moreover, it is necessary to increase the number of individuals receiving follow-up and encourage multidisciplinary work between physical therapists and other primary healthcare professionals.

RESUMO Após a alta hospitalar, recomenda-se que pacientes pós-AVC sejam acompanhados por um fisioterapeuta durante toda a recuperação. Apesar das recomendações clínicas, poucos estudos investigaram os cuidados fisioterapêuticos a indivíduos pós-AVC residindo na comunidade. O estudo objetivou descrever os cuidados fisioterapêuticos prestados a indivíduos que sofreram AVC residentes na comunidade em contexto de atenção primária e identificar as características clínico-funcionais e sociodemográficas que determinam a assistência de fisioterapia. Este é um estudo transversal exploratório. Foram incluídos pacientes pós-AVC, residentes na comunidade e que foram atendidos pela equipe multidisciplinar de quatro unidades de atenção primária à saúde de uma importante metrópole brasileira. Os prontuários foram analisados para identificar os cuidados prestados pelos fisioterapeutas. Os indivíduos que receberam e não receberam cuidados fisioterapêuticos foram comparados (α=0,05). Dos 100 indivíduos incluídos, 55% receberam assistência de profissionais da equipe multidisciplinar e 44% foram atendidos por fisioterapeutas. As abordagens de fisioterapia consistiram principalmente em instruções (89%) e avaliações (75%). Apenas 45% dos indivíduos que receberam cuidados fisioterapêuticos foram acompanhados, e aqueles que receberam esses cuidados apresentaram um número significativamente maior de eventos de AVC e níveis mais altos de incapacidade (p<0,001). Observou-se que muitas pessoas com diferentes níveis de incapacidade não receberam assistência fisioterapêutica. Além disso, o acompanhamento e os encaminhamentos não foram frequentes nas práticas fisioterapêuticas. Portanto, os cuidados fisioterapêuticos na atenção primária precisam ser ampliados para garantir que todos os indivíduos com algum nível de incapacidade recebam tratamento. Ademais, é preciso aumentar o número de indivíduos que recebem acompanhamento e incentivar o trabalho multidisciplinar entre fisioterapeutas e outros profissionais da área de saúde.

Accuracy of duplex ultrasonography versus angiotomography for the diagnosis of extracranial internal carotid stenosis / Acurácia da ultrassonografia duplex comparada à angiotomografia para o diagnóstico de estenose de carótida interna extracraniana

ABSTRACT Introduction: Internal carotid artery (ICA) stenosis causes about 15% of ischemic strokes. Duplex ultrasonography (DUS) is the first line of investigation of ICA stenosis, but its accuracy varies in the literature and it is usual to complement the study with another more accurate exam when faced with significant stenosis. There is a lack of studies that compare DUS with angiotomography (CTA) in the present literature. Methods: we performed an accuracy study, which compared DUS to CTA of patients in a tertiary hospital with a maximum interval of three months between tests. Patients were selected retrospectively, and two independent and certified vascular surgeons evaluated each image in a masked manner. When there was discordance, a third evaluator was summoned. We evaluated the diagnostic accuracy of ICA stenosis of 50-94% and 70-94%. Results: we included 45 patients and 84 arteries after inclusion and exclusion criteria applied. For the 50-94% stenosis range, DUS accuracy was 69%, sensitivity 89%, and specificity 63%. For the 70-94% stenosis range, DUS accuracy was 84%, sensitivity 61%, and specificity 93%. There was discordance between CTA evaluators with a change from clinical to surgical management in at least 37.5% of the conflicting reports. Conclusion: DUS had an accuracy of 69% for stenoses of 50-94% and 84% for stenoses of 70-94% of the ICA. The CTA analysis depended directly on the evaluator with a change in clinical conduct in more than 37% of cases.

RESUMO Introdução: a estenose da artéria carótida interna (ACI) causa cerca de 15% dos acidentes vasculares cerebrais isquêmicos. A ultrassonografia duplex (USD) é a primeira linha de investigação da estenose de ACI, mas sua acurácia varia na literatura e é comum complementar o estudo com outro exame de maior acurácia diante de estenose significativa. Há uma escassez de estudos que comparem a USD com a angiotomografia computadorizada (ATC) na literatura atual. Métodos: realizamos um estudo de acurácia, que comparou a USD à ATC de pacientes de um hospital terciário com um intervalo máximo de três meses entre os exames. Os pacientes foram selecionados retrospectivamente e dois cirurgiões vasculares independentes e certificados avaliaram cada imagem de maneira mascarada. Quando houve discordância, um terceiro avaliador foi convocado. Avaliou-se a precisão diagnóstica da estenose da ACI de 50-94% e 70-94%. Resultados: foram incluídos 45 pacientes e 84 artérias após a aplicação dos critérios de inclusão e exclusão. Para a faixa de estenose de 50-94%, a acurácia da USD foi 69%, sensibilidade 89% e especificidade 63%. Para a faixa de estenose de 70-94%, a acurácia da USD foi 84%, sensibilidade 61% e especificidade 93%. Ocorreu discordância entre avaliadores da ATC com mudança de conduta clínica para cirúrgica em pelo menos 37,5% dos laudos conflitantes. Conclusão: a USD teve uma acurácia de 69% para estenoses de 50-94% e de 84% para estenoses de 70-94% da ACI. A análise das ATC dependeu diretamente do avaliador com mudança de conduta clínica em mais de 37% dos casos.
