ABSTRACT

ABSTRACT Background: There is a high demand for stroke patient data in the public health systems of middle and low-income countries. Objective: To develop a stroke databank for integrating clinical or functional data and benchmarks from stroke patients. Methods: This was an observational, cross-sectional, prospective study. A tool was developed to collect all clinical data during hospitalizations due to stroke, using an electronic editor of structured forms that was integrated with electronic medical records. Validation of fields in the electronic editor was programmed using a structured query language (SQL). To store the results from SQL, a virtual table was created and programmed to update daily. To develop an interface between the data and user, the Embarcadero Delphi software and the DevExpress component were used to generate the information displayed on the screen. The data were extracted from the fields of the form and also from cross-referencing of other information from the computerized system, including patients who were admitted to the stroke unit. Results: The database was created and integrated with the hospital electronic system, thus allowing daily data collection. Quality indicators (benchmarks) were created in the database for the system to track and perform decision-making in conjunction with healthcare service managers, which resulted in improved processes and patient care after a stroke. An intelligent portal was created, in which the information referring to the patients was accessible. Conclusions: Based on semi-automated data collection, it was possible to create a dynamic and optimized Brazilian stroke databank.


RESUMO Antecedentes: Há alta demanda de dados de pacientes com acidente vascular cerebral (AVC) nos sistemas de saúde de países de baixa e média renda. Objetivo: Desenvolver um banco de dados de AVC para integrar dados clínicos ou funcionais e indicadores de qualidade de pacientes com AVC. Métodos: Estudo observacional, transversal e prospectivo. Foi desenvolvida uma ferramenta para coletar dados clínicos durante as internações por AVC por meio de um editor eletrônico de formulários estruturados integrado ao prontuário eletrônico. A validação dos campos no editor eletrônico foi programada em linguagem de consulta estruturada (SQL). Para armazenar os resultados da SQL, uma tabela virtual foi criada e programada para atualização diária. Para desenvolver interface entre os dados e o usuário, foram utilizados o software Embarcadero Delphi e o componente DevExpress para gerar informações apresentadas na tela. Os dados foram extraídos dos campos do formulário e também do cruzamento de outras informações do sistema informatizado, incluindo pacientes internados na unidade de AVC. Resultados: O banco de dados foi criado e integrado ao sistema eletrônico do hospital, permitindo coleta diária de dados. Indicadores de qualidade foram criados no banco de dados para que o sistema acompanhasse e realizasse a tomada de decisão com os gestores dos serviços de saúde, resultando em melhoria no processo e no atendimento ao paciente após AVC. Foi criado um portal inteligente, no qual eram registradas as informações referentes aos pacientes. Conclusões: Com a coleta de dados semiautomática, foi possível criar um banco de dados de AVC dinâmico e otimizado em unidade de AVC no Brasil.

ABSTRACT

Abstract Background: Patent foramen ovale (PFO) has been considered a potential mechanism of embolic stroke of undetermined origin. Objective: The aim of the present study was to identify the features of the right-to-left shunt (RLS) in patients with undetermined embolic ischemic stroke and compare them with those of patients with non-cardioembolic ischemic stroke. Methods: A retrospective study was conducted with 168 patients with stroke and RLS separated into the following two groups: the undetermined embolic stroke group (UES group) and non-cardioembolic stroke group (NCES group). All patients were assessed by transcranial Doppler to evaluate the presence and quantification of microembolic signals (MES) at rest and under Valsalva maneuver. Results: Of all patients evaluated in the current study, 96 were included in the UES group and 72 in the NCES group. In the UES group, 65 patients had RLS with ≥10 MES (67.7%), which was higher than that observed in the NCES group (51.4%, p=0.038). According to the moment of the cardiac cycle, 75 patients (78.1%) in the UES group had a positive test at rest compared to 42 (58.3%) in the NCES group (p=0.007). Conclusions: The current study demonstrated that almost 70% of patients with undetermined embolic stroke and PFO presented a large RLS and more than 75% had RLS at rest. These findings suggest that the size of the shunt should be taken into account when evaluating whether PFO could be a possible mechanism underlying cryptogenic stroke.


RESUMO Antecedentes: Uma das potenciais fontes embólicas no acidente vascular cerebral (AVC) de origem indeterminada é o forame oval patente (FOP). Objetivo: O objetivo do presente estudo foi identificar as características do shunt direita-esquerda em paciente com AVC de etiologia indeterminada, presumidamente embólica, e comparar tais características com pacientes apresentando AVC por outras causas não embólicas. Métodos: Trata-se de um estudo retrospectivo com 168 pacientes com AVC e forame oval patente, separados em dois grupos: AVC embólico de etiologia indeterminada e AVC por outras causas não embólicas. Todos os pacientes foram submetidos a Doppler transcraniano, para avaliar a presença de shunt direita-esquerda por meio do teste de embolia paradoxal. Além da quantificação de microbolhas, também foi avaliada a presença de shunt em repouso e sob manobra de Valsalva. Resultado: Do total, 96 pacientes foram incluídos no primeiro grupo (AVC indeterminado) e 72, no segundo grupo (AVC não embólico). No primeiro grupo, 65 pacientes exibiram shunt com passagem de mais de 10 microbolhas (67,5%), enquanto no segundo grupo isso aconteceu em 51,4% (p=0,038) dos casos. Além disso, 75 pacientes (78,1%) do primeiro grupo tiveram teste positivo ao repouso, comparados com 42 pacientes (58,3%) no segundo grupo (p=0,007). Conclusão: O presente estudo demonstrou que até 70% dos pacientes com AVC de etiologia indeterminada e forame oval apresentaram shunts maiores; em mais de 75%, houve passagem de microbolhas ao repouso. Esses achados sugerem que as características do shunt, como quantidade de microbolhas e passagem ao repouso, devem ser levadas em consideração na avaliação do FOP como possível mecanismo subjacente ao AVC.

ABSTRACT

ABSTRACT Background: It has been shown that the autonomic nervous system can be modulated by physical exercise after stroke, but there is a lack of evidence showing rehabilitation can be effective in increasing heart rate variability (HRV). Objective: To investigate the effectiveness and safety of rehabilitation programs in modulating HRV after stroke. Methods: The search strategy was based in the PICOT (patients: stroke; interventions: rehabilitation; comparisons: any control group; outcomes: HRV; time: acute, subacute and chronic phases of stroke). We searched MEDLINE, CENTRAL, CINAHL, LILACS, and SCIELO databases without language restrictions, and included randomized controlled trials (RCTs), quasi-randomized controlled trials (quasi-RCTs), and non-randomized controlled trials (non-RCTs). Two authors independently assessed the risk of bias and we used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology to rate the certainty of the evidence for each included study. Results: Four studies (two RCTs with low certainty of the evidence and two non-RCTs with very low certainty of the evidence) were included. Three of them showed significant cardiac autonomic modulation during and after stroke rehabilitation: LF/HF ratio (low frequency/high frequency) is higher during early mobilization; better cardiac autonomic balance was observed after body-mind interaction in stroke patients; and resting SDNN (standard deviation of normal R-R intervals) was significantly lower among stroke patients indicating less adaptive cardiac autonomic control during different activities. Conclusions: There are no definitive conclusions about the main cardiac autonomic repercussions observed in post-stroke patients undergoing rehabilitation, although all interventions are safe for patients after stroke.


RESUMO Antecedentes: O sistema nervoso autônomo pode ser modulado pelo exercício físico após o acidente vascular cerebral (AVC), mas faltam evidências que demonstrem que a reabilitação pode ser eficaz no aumento da variabilidade da frequência cardíaca (VFC). Objetivo: Investigar a eficácia e segurança dos programas de reabilitação na modulação da VFC após o AVC. Métodos: A estratégia de busca foi baseada na estratégia PICOT (pacientes: AVC; intervenções: reabilitação; comparações: qualquer grupo de controle; desfechos: VFC; tempo: fase aguda, subaguda e crônica). Foi realizada busca nas bases MEDLINE, CENTRAL, CINAHL, LILACS e SCIELO sem restrições de idioma, sendo incluídos ensaios clínicos randomizados (ECRs), ensaios clínicos quasi-randomizados (quasi-ECRs) e ensaios clínicos não-randomizados (não-ECRs). Dois autores avaliaram independentemente o risco de viés e a metodologia GRADE para classificar a certeza das evidências para cada estudo incluído. Resultados: Quatro estudos (dois ECRs com baixa certeza de evidência e dois não-ECRs com muito baixa certeza de evidência) foram incluídos. Três deles apresentaram modulação autonômica cardíaca durante e após a reabilitação: a razão LF/HF (low frequency/high frequency) foi maior durante a mobilização precoce; maior equilíbrio autonômico foi observado após prática de interação corpo-mente após AVC; e SDNN (desvio padrão dos intervalos R-R normais) foi significativamente menor em pacientes com AVC indicando menor adaptação autonômica cardíaca durante diferentes atividades. Conclusões: Não há conclusão definitivas sobre as principais repercussões cardíaca autonômica nos pacientes com AVC na reabilitação, embora todas as intervenções foram seguras para os pacientes após AVC.

ABSTRACT

Resumo Fundamento: A incidência de reestenose da artéria coronária após o implante de um stent não farmacológico é mais baixa que na angioplastia com balão; no entanto, ainda apresenta altas taxas. Objetivo: O objetivo deste estudo foi identificar novos indicadores de risco para reestenose de stent usando ultrassonografia das carótidas que, em conjunto com indicadores já existentes, ajudariam na escolha do stent. Métodos: Realizamos um estudo prospectivo transversal incluindo 121 pacientes consecutivos com doença arterial coronariana que foram submetidos à intervenção coronária percutânea com angiografia nos 12 meses anteriores. Após os casos de reestenose de stent serem identificados, os pacientes foram submetidos à ultrassonografia de carótidas para avaliar a espessura da camada íntima média e placas ateroscleróticas. Os dados foram analisados por regressão múltipla de Cox. O nível de significância foi p<0,05. Resultados: A idade mediana dos pacientes foi de 60 anos (1º quartil = 55, 3º quartil = 68), e 64,5% dos pacientes eram do sexo masculino. A angiografia coronária mostrou que 57 pacientes (47,1%) apresentaram reestenose de stent. Cinquenta e cinco pacientes (45,5%) apresentaram placas ateroscleróticas ecolucentes nas artérias carótidas e 54,5% apresentaram placas ecogênicas ou nenhuma placa. Dos pacientes que apresentaram placas ecolucentes, 90,9% apresentaram reestenose do stent coronário, e daqueles com placas ecogênicas ou nenhuma placa, 10,6% apresentaram reestenose de stent. A presença de placas ecolucentes nas artérias carótidas aumentou o risco de reestenose de stent coronário em 8,21 vezes (RR=8,21;IC95%: 3,58-18,82; p<0,001). Conclusões: A presença de placas ateroscleróticas ecolucentes na artéria carótida constitui um preditor de risco de reestenose de stent coronário e deve ser considerada na escolha do tipo de stenta ser usado na angioplastia coronária.


Abstract Background: The incidence of restenosis of the coronary artery after a bare-metal stent implant has been lower than in simple balloon angioplasty; however, it still shows relatively high rates. Objective: The aim of this study was to find new risk indicators for in-stent restenosis using carotid ultrasonography, that, in addition to the already existing indicators, would help in decision-making for stent selection. Methods: We carried out a cross-sectional prospective study including 121 consecutive patients with chronic coronary artery disease who had undergone percutaneous coronary intervention with repeat angiography in the previous 12 months. After all cases of in-stent restenosis were identified, patients underwent carotid ultrasonography to evaluate carotid intima-media thickness and atherosclerosis plaques. The data were analyzed by Cox multiple regression. The significance level was set a p<0.05. Results: Median age of patients was 60 years (1st quartile = 55, 3rd quartile = 68), and 64.5% of patients were male. Coronary angiography showed that 57 patients (47.1%) presented in-stent restenosis. Fifty-five patients (45.5%) had echolucent atherosclerotic plaques in carotid arteries and 54.5% had echogenic plaques or no plaques. Of patients with who had echolucent plaques, 90.9% presented coronary in-stent restenosis. Of those who had echogenic plaques or no plaques, 10.6% presented in-stent restenosis. The presence of echolucent plaques in carotid arteries increased the risk of coronary in-stent restenosis by 8.21 times (RR=8.21; 95%CI: 3.58-18.82; p<0.001). Conclusions: The presence of echolucent atherosclerotic plaques in carotid artery constitutes a risk predictor of coronary instent restenosis and should be considered in the selection of the type of stent to be used in coronary angioplasty.

ABSTRACT

ABSTRACT Background: Use of internationally standardized instruments to assist healthcare professionals in accurately recognizing stroke early is recommended. The process of translation and cross-cultural adaptation is important for ensuring that scales are interpreted in the same way in different languages, thus ensuring applicability in several countries. Objective: To translate into Brazilian Portuguese, cross-culturally adapt and validate the Cincinnati Prehospital Stroke Scale, using a representative sample of the Brazilian population. Method: The present study included patients with suspected stroke who were treated at a Brazilian emergency medical service and referred to a stroke center. A systematic process of translation and cross-cultural adaptation of the original scale and application of the final instrument was performed. Statistical analysis was used to assess the sensitivity, specificity and accuracy of the scale. Cohen's kappa coefficient was used to assess inter-rater reliability. Results: After translation and cross-cultural adaptation, the scale was applied to 64 patients. It showed 93.0% accuracy and 92.4% sensitivity in relation to the final "gold standard" diagnosis. Cohen's kappa coefficient was calculated using data from 26 patients (40.6%) and showed excellent inter-rater reliability between items on the scale (0.8385 to 1.0000). Conclusion: The scale demonstrated excellent accuracy, sensitivity and inter-rater reliability. It was a useful tool for assisting healthcare professionals during initial assessments on patients with suspected stroke and significantly contributed to early recognition of stroke in a simple and quick manner.

ABSTRACT

ABSTRACT Cannabinoids comprehend endocannabinoids, phytocannabinoids, and synthetic cannabinoids, with actions both in the central and peripherical nervous systems. A considerable amount of publications have been made in recent years, although cannabis has been known for over a thousand years. Scientific Departments from the Brazilian Academy of Neurology described evidence for medical use in their areas. Literature is constantly changing, and possible new evidence can emerge in the next days or months. Prescription of these substances must be discussed with patients and their families, with knowledge about adverse events and their efficacy.

ABSTRACT

Abstract Background Neuroimaging is widely used for diagnosis and treatment of stroke. However, little is known about whether the radiation doses received by patients comply with international safety guidelines. Objectives The aim of this study was to evaluate the effective radiation dose received while in hospital for stroke and analyze its safety according to current guidelines. Methods This cross-sectional study included 109 patients who were hospitalized and diagnosed with ischemic stroke. The National Institutes of Health Stroke Scale was used to evaluate stroke severity, the Bamford clinical classification was used for topography, and the TOAST classification was used for etiology. The computed tomography dose index and size-specific dose estimates were used to calculate the effective radiation dose (ERD) received while in hospital. A Mann-Whitney test was used to compare the ERD received by thrombolysed and non-thrombolysed patients. Non-parametric statistics were used to analyze the data with a 95% confidence interval. Results During the study period, the median ERD received was 10.9 mSv. Length of stay was not associated with radiation exposure. No differences were demonstrated in ERD according to stroke etiology or Bamford clinical classification. Patients who had CT perfusion (only or in addition to CT or angiotomography) received the highest ERD (46.5 mSv) and the difference compared to those who did not (10.8 mSv) was statistically significant (p<0.001). No differences were found in the ERD between thrombolysed and non-thrombolysed patients. There was no correlation between ERD while in hospital and stroke severity. Conclusions According to the current national guidelines, the protocol for examining images at our stroke unit is safe in terms of the ERD received by the patient while in hospital. There was no difference in the ERD received by patients stratified by thrombolytic treatment or stroke severity.


Resumo Contexto A neuroimagem é amplamente utilizada para o diagnóstico e tratamento do acidente vascular cerebral (AVC). No entanto, pouco se sabe se a dose de radiação recebida nesses exames está de acordo com as diretrizes internacionais de segurança. Objetivos O objetivo deste estudo foi avaliar a dose de radiação efetiva (DRE) durante a hospitalização por AVC. Métodos Trata-se de estudo transversal com 109 pacientes hospitalizados com diagnóstico de AVC isquêmico. A gravidade do AVC foi avaliada pela National Institutes of Health Stroke Scale, a topografia pela classificação clínica de Bamford e a etiologia pelo Trial of ORG 10172 in Acute Stroke Treatment (TOAST). O índice de dose recebida no exame de tomografia computadorizada (TC) e as estimativas de dose específicas foram usados ​​para calcular a DRE recebida durante a hospitalização. O teste de Mann-Whitney foi utilizado para comparar a DRE recebida por pacientes trombolisados ​​e não trombolisados. Estatísticas não paramétricas foram utilizadas para analisar os dados. Resultados Durante o período do estudo, a DRE foi de 10,9 mSv. O tempo de internação não foi associado à exposição à radiação. Nenhuma diferença foi demonstrada na DRE de acordo com a etiologia e classificação clínica de Bamford. Os pacientes que fizeram perfusão (isolada, associada à TC ou angiotomografia) receberam a maior DRE (46,5 mSv) em comparação aos que não fizeram (10,8 mSv), sendo estatisticamente significativo (p <0,001). Não foram encontradas diferenças na DRE entre pacientes trombolisados e não trombolisados. Não houve correlação entre a DRE durante a hospitalização com a gravidade do AVC. Conclusões De acordo com as atuais diretrizes nacionais, o protocolo de exame de imagens na unidade de AVC é seguro em relação à DRE recebido pelo paciente durante a internação. Não houve diferença na DRE dos pacientes de acordo com o tratamento trombolítico e a gravidade do AVC.

ABSTRACT

OBJECTIVES: Coronary artery disease is the primary cause of death and is responsible for a high number of hospitalizations worldwide. Ventricular remodeling is associated with worse prognosis following ST-segment elevation myocardial infarction (STEMI) and is a risk factor for ventricular dysfunction and heart failure. This study aimed to identify the predictors of ventricular remodeling following STEMI. Additionally, we evaluated the clinical, laboratory, and echocardiographic characteristics of patients with anterior wall STEMI who underwent primary percutaneous intervention in the acute phase and at 6 months after the infarction. METHODS: This prospective, observational, and longitudinal study included 50 patients with anterior wall STEMI who were admitted to the coronary care unit (CCU) of a tertiary hospital in Brazil between July 2017 and August 2018. During the CCU stay, patients were evaluated daily and underwent echocardiogram within the first three days following STEMI. After six months, the patients underwent clinical evaluation and echocardiogram according to the local protocol. RESULTS: Differences were noted between those who developed ventricular remodeling and those who did not in the mean±standard deviation levels of creatine phosphokinase MB isoenzyme (CKMB) peak (no remodeling group: 323.7±228.2 U/L; remodeling group: 522.4±201.6 U/L; p=0.008) and the median and interquartile range of E/E' ratio (no remodeling group: 9.20 [8.50-11.25] and remodeling group: 12.60 [10.74-14.40]; p=0.004). This difference was also observed in multivariate logistic regression. CONCLUSIONS: Diastolic dysfunction and CKMB peak in the acute phase of STEMI can be predictors of ventricular remodeling following STEMI.

ABSTRACT

ABSTRACT Purpose: this study aimed to verify the occurrence of abnormal vectoelectronystagmography findings in patients with temporomandibular disorders (TMDs). Methods: in this cross-sectional study, patients diagnosed with TMDs underwent an otorhinolaryngological examination, audiological evaluation, and balance and vestibular function examinations, using vectoelectronystagmography. The tests performed were 1) spontaneous nystagmus, 2) saccadic movements, 3) pendular tracking, 4) optokinetic nystagmus gain and velocity, 5) rotational chair testing, and 6) post-caloric vertigo and the direction and velocity of the slow component of nystagmus. Results: thirty patients were selected (22 females and 8 males) with mean age of 30.8(14.9 years. Sensorineural hearing loss was seen in four patients (13.3%); the other patients (86.7%) had results within the normal range at all frequencies. Five patients (16.7%) showed abnormalities on the Romberg test and seven (23.3%) on the Tandem test. Abnormalities on the caloric test were seen in 40.0% of patients. More prevalence of headache (p<0.0001) and tinnitus (p<0.0001) was observed in patients with unilateral hyperreflexia, and dizziness, depression, anxiety, gait imbalance and falls in patients with bilateral hyperreflexia. Conclusion: patients with TMDs may present vectoelectronystagmography abnormalities characterized by unilateral or bilateral hyperreflexia and unilateral hyporeflexia of post-caloric nystagmus.

ABSTRACT

Resumo A cardiomiopatia hipertrófica (CMH) é a doença cardíaca de origem genética mais comum, cuja principal característica consiste na hipertrofia ventricular esquerda que acontece na ausência de outras patologias que desencadeiam tal alteração. A CMH pode se apresentar desde formas assintomáticas até manifestações de morte cardíaca súbita e de insuficiência cardíaca refratária. Métodos de imagem contemporâneos de alta resolução e escores clínicos mais acurados vêm sendo utilizados e desenvolvidos no sentido de propiciar uma avaliação prognóstica e funcional mais adequada, bem como possibilitar a estratificação dos casos de maior gravidade. Nesta revisão, serão abordados esses aspectos, entre outros tópicos clássicos inerentes ao estudo dessa doença.


Abstract Hypertrophic cardiomyopathy (HCM) is the most common heart disease with a genetic origin, and its main characteristic is left ventricular hypertrophy that occurs in the absence of other conditions that trigger this change. HCM may present from asymptomatic forms to manifestations of sudden cardiac death and severe heart failure. Contemporary high-resolution imaging methods and more accurate clinical scores have been used and developed to provide a prognostic assessment and adequate functional assessments, as well as to allow for the stratification of clinical severity. These aspects will be addressed in this review, along with other classic topics inherent to the study of this disease.

ABSTRACT

ABSTRACT Introduction: Although the 2019 severe acute respiratory syndrome coronavirus 2 infection (SARS-CoV-2, COVID-19) pandemic poses new challenges to the healthcare system to provide support for thousands of patients, there is special concern about common medical emergencies, such as stroke, that will continue to occur and will require adequate treatment. The allocation of both material and human resources to fight the pandemic cannot overshadow the care for acute stroke, a time-sensitive emergency that with an inefficient treatment will further increase mortality and long-term disability. Objective: This paper summarizes the recommendations from the Scientific Department on Cerebrovascular Diseases of the Brazilian Academy of Neurology, the Brazilian Society of Cerebrovascular Diseases and the Brazilian Society of Neuroradiology for management of acute stroke and urgent neuro-interventional procedures during the COVID-19 pandemic, including proper use of screening tools, personal protective equipment (for patients and health professionals), and patient allocation.


RESUMO Introdução: A pandemia causada pelo novo coronavírus da síndrome respiratória aguda grave 2 (SARS-CoV-2, COVID-19) apresenta novos e importantes desafios à gestão de saúde no Brasil. Além da difícil missão de prestar atendimento aos milhares de pacientes infectados pelo COVID-19, os sistemas de saúde têm que manter a assistência às emergências médicas comuns em períodos sem pandemia, tais como o acidente vascular cerebral (AVC), que continuam ocorrendo e requerem tratamento com presteza e eficiência. A alocação de recursos materiais e humanos para o enfrentamento à pandemia não pode comprometer o atendimento ao AVC agudo, uma emergência cujo tratamento é tempo-dependente e se não realizado implica em importante impacto na mortalidade e incapacitação a longo prazo. Objetivo: Este trabalho resume as recomendações do Departamento Científico de Doenças Cerebrovasculares da Academia Brasileira de Neurologia, da Sociedade Brasileira de Doenças Cerebrovasculares e da Sociedade Brasileira de Neurorradiologia para o tratamento do AVC agudo e para a realização de procedimentos de neurointervenção urgentes durante a pandemia de COVID-19, incluindo o uso adequado de ferramentas de triagem e equipamentos de proteção pessoal (para pacientes e profissionais de saúde), além da alocação apropriada de pacientes.

ABSTRACT

ABSTRACT Patients with peripheral facial paralysis (PFP) have some degree of recovery. The aim of this study was to evaluate prognostic factors and physical therapy modalities associated with functional recovery in patients with PFP. This is a cohort study with 33 patients. We collected the following variables of patients who underwent treatment at the rehabilitation center: age, sex, risk factors, affected side, degree of facial paralysis (House-Brackmann scale), start of rehabilitation, and therapy modality (kinesiotherapy only; kinesiotherapy with excitomotor electrotherapy; and kinesiotherapy with excitomotor electrotherapy and photobiomodulation therapy). The outcomes were: degree of facial movement (House-Brackmann) and face scale applied 90 days after treatment. Degree of PFP was associated with functional recovery (RR=0.51, 95% CI: 0.51-0.98; p=0.036). The facial movement was associated with the time to start rehabilitation (r=−0.37; p=0.033). Lower facial comfort was observed among women, worse ocular comfort was associated with diabetes mellitus, worse tear control with prior PFP, and worse social function with the degree of PFP. Our results indicate that the all modalities present in this study showed the same result in PFP. Recovery of PFP was associated with degree of nerve dysfunction, the length of time to onset of rehabilitation, female sex, hypertension, diabetes mellitus, and previous PFP, all of which were associated with worse outcomes on the face scale.


RESUMO Os pacientes com paralisia facial periférica (PFP) apresentam diversos graus de recuperação. O objetivo deste estudo foi avaliar os fatores prognósticos e as modalidades fisioterapêuticas associados à recuperação funcional em pacientes com PFP. Trata-se de um estudo coorte prospectiva de 33 pacientes. Foram coletadas variáveis de pacientes submetidos ao tratamento no centro de reabilitação: idade, sexo, fatores de risco, lado afetado, grau de paralisia facial (escala de House-Brackmann), início da reabilitação e modalidade de terapia (cinesioterapia; cinesioterapia associada à eletroterapia; cinesioterapia associada à eletroterapia e terapia de fotobiomodulação). Os desfechos foram: grau de movimento facial (House-Brackmann) e face scale aplicados 90 dias após o tratamento. O grau de PFP foi associado à recuperação funcional (RR=0,51, 95% IC: 0,51-0,98; p=0,036). O movimento facial foi associado com o tempo para iniciar a reabilitação (r=−0,37; p=0,033). Menor conforto facial foi observado entre as mulheres, pior conforto ocular em indivíduos com diabetes mellitus, pior controle lacrimal em indivíduos com PFP prévia e pior função social com o grau de PFP. Todas as modalidades apresentadas neste estudo tiveram o mesmo resultado na PFP. A recuperação da PFP foi associada ao grau de disfunção nervosa, ao tempo de início da reabilitação, ao sexo feminino, à hipertensão arterial sistêmica, ao diabetes mellitus e à PFP prévia, todos associados a piores desfechos na face scale.

ABSTRACT

Abstract Ischemic stroke is a common cause of death. The role of statins in the secondary prevention of the chronic ischemic stroke phase has been established. However, evidence regarding their efficacy in this phase is limited and contradictory. Objective: To evaluate the association between statin use and mortality risk during the acute phase of ischemic stroke in patients admitted to an intensive care unit. Methods: This was an observational and prospective study of ischemic stroke patients aged ≥18, admitted to an intensive care unit. Medications used during the first 7 days after the ictus, as well as medications used previously, were recorded. The primary outcome was all-cause mortality during the first 7 days. Results: We screened 212 patients and included 97 patients with ischemic stroke in the study period. The mortality rate among patients who used statins during the acute IS phase [14% (9/63)] was significantly lower than that among patients who did not use statins [41% (14/34); p=0.007]. This was confirmed in logistical regression with an 0.19 Odds Ratio - OR [p=0.018; 95% confidence interval - 95%CI 0.05-0.75]. Patients who died were older, had a higher incidence of acute myocardial infarction, higher scores on the NIHSS and lower systolic blood pressure. Statins and angiotensin converting enzyme inhibitors were used more frequently among survivors. These associations persisted even after adjustment for confounding variables. Conclusion: Statins and angiotensin converting enzyme inhibitors use during hospitalization were independently associated to a lower rate of all-cause mortality in the first 7 days of intensive care unit admission.


Resumo O acidente vascular cerebral (AVC) isquêmico é uma causa comum de morte. O papel das estatinas na prevenção secundária da fase crônica do AVC isquêmico foi estabelecido. No entanto, as evidências sobre a sua eficácia na fase aguda do AVC isquêmico são limitadas e contraditórias. Objetivo: Avaliar a associação entre o uso de estatinas e o risco de mortalidade durante a fase aguda do AVC isquêmico em pacientes internados em uma unidade de terapia intensiva. Métodos: Estudo observacional e prospectivo de pacientes com AVC isquêmico com idade ≥18 anos, internados em uma unidade de terapia intensiva. Os medicamentos utilizados durante os primeiros 7 dias após o ictus, bem como os medicamentos utilizados anteriormente, foram registrados. O desfecho primário foi mortalidade por todas as causas durante os primeiros 7 dias. Resultados: Foram selecionados 212 pacientes e incluídos 97 pacientes com AVC isquêmico no período do estudo. A taxa de mortalidade entre os pacientes que usaram estatinas durante a fase aguda do AVC [14% (9/63)] foi significativamente menor do que a dos pacientes que não usaram estatinas [41% (14/34); p=0,007]. Isso foi confirmado na regressão logística com Odds Ratio - OR 0,19 [p=0,018; intervalo de confiança de 95% - IC95% 0,05-0,75]. Os pacientes que morreram eram mais velhos, apresentavam maior incidência de infarto agudo do miocárdio, escores mais altos na National Institute of Health Stroke Scale (NIHSS) e menor pressão arterial sistólica. Estatinas e inibidores da enzima conversora de angiotensina foram utilizados com maior frequência entre os sobreviventes. Essas associações persistiram mesmo após o ajuste para variáveis de confundimento. Conclusão: O uso de estatinas e inibidores da enzima conversora de angiotensina durante a hospitalização foram associados de forma independente à uma menor taxa de mortalidade por todas as causas nos primeiros 7 dias de internação na unidade de terapia intensiva.

ABSTRACT

OBJECTIVE: Unilateral spatial neglect (USN) results in a consistent and exaggerated spatial asymmetry in the processing of information about the body or space due to an acquired brain injury. There are several USN tests for clinical diagnosis, but none of them are validated in Brazil. The aim was to obtain normative values from a healthy sample in Brazil and to evaluate the effects of demographic variables on USN tests. METHODS: This was a cross-sectional study performed with 150 neurologically healthy individuals. USN was evaluated using the line cancelation (LC), star cancelation (SC), and line bisection (LB) tests in the A3 (29.7 x 42.0 cm) sheet format. RESULTS: In LC, 143 participants had 0 omissions, and the occurrence of failure was significantly associated with aging (OR=1.1[1.02-1.2]; p=0.012). In SC, 145 participants had fewer than 1 omission, and the occurrence of failure was significantly associated with aging (OR=1.07[1.03-1.11]; p<0.001). In LB, deviations were the lowest for those with the highest level of education (r=0.20; p=0.015), and the deviation was 9.5 mm. CONCLUSION: The cutoff points presented in this study may be indicative of USN, but due to performance differences based on age, we suggest using different norm scores for different age groups. These norm scores can be used in the clinic immediately for USN diagnosis.

ABSTRACT

ABSTRACT The objective of this study is to evaluate the effects of physical therapy on the cognitive and functional capacity of patients with Alzheimer's Disease (AD). This is a systematic review of randomized or quasi-randomized clinical trials, using the descriptors: AD, dementia and physical therapy. Two studies were included with a total of 207 participants. In study 1, no statistically significant difference was found on the mini-mental state examination (MMSE) (MD 0.0, 95%CI −5.76 to 5.76), neuropsychiatric inventory (MD −4.50, 95%CI −21.24 to 12.24) and Pfeffer instrumental activities questionnaire (MD 0.0 95%CI −6.48 to 6.48). In study 2, there was no statistically significant difference on the MMSE (MD −1.60, 95% CI −3.57 to 0.37), clock-drawing test (MD −0.20, 95%CI −0.61 to 0.21) and Alzheimer's Disease Assessment Scale - cognitive subscale (MD 1.0, 95%CI −2.21 to 4.21) after 12 months. There was no consistent evidence on the effectiveness of physiotherapeutic intervention in improving cognitive function and functional capacity of patients with AD. More studies should be conducted for better evidence.


RESUMO O objetivo do estudo é avaliar os efeitos da fisioterapia na capacidade cognitiva e funcional de pacientes com doença de Alzheimer (DA). Trata-se de revisão sistemática de ensaios clínicos randomizados ou quasi-randomizados utilizando os descritores: DA, demência e fisioterapia. Dois estudos foram incluídos, com um total de 207 participantes. No Estudo 1, não houve diferença estatisticamente significativa no miniexame do estado mental (MEEM) (MD 0,0, IC 95% 5,76−5,76), inventário neuropsiquiátrico (MD −4,50, IC 95% 12,24−21,24) e questionário de atividades instrumentais Pfeffer (MD 0,0 IC 95% −6,48 a 6,48). No Estudo 2, não houve diferença estatisticamente significativa no MEEM (MD −1,60, IC 95% −3,57 a 0,37), teste do desenho do relógio (MD −0,20, IC95% −0,61 a 0,21) e escala de avaliação da doença de Alzheimer - subitem cognição (MD 1,0, IC95% −2,21 a 4,21) após 12 meses. Não houve evidência consistente da eficácia da intervenção fisioterapêutica na melhora da função cognitiva e capacidade funcional na DA. Recomenda-se a produção de mais estudos para encontrar possíveis evidências.

ABSTRACT

ABSTRACT Embolic stroke of undetermined source (ESUS) is an important group of cryptogenic strokes that are in evidence due recent ongoing trials. We reviewed medical records at discharge from the stroke unit of all patients who met ESUS criteria and attended our institution between February 2016 and July 2017. Among 550 stroke patients, 51 had ESUS. We found that hypertension (60%), diabetes mellitus (34%), and smoking (36%) were the most prevalent risk factors. The mean National Institutes of Health Stroke Scale (NIHSS) scores were 7 at admission and 4 at discharge, while median scores on the modified Rankin scale were 0 and 2 at admission and discharge, respectively. Our sample had similar ages, risk factors prevalence and NIHSS scores at admission and discharge when compared with European and North American cohorts. Although a small cohort, our study suggests that the ESUS population is similar in countries with different health financing.


RESUMO Acidentes vasculares cerebrais (AVC) embólicos de fonte indeterminada (ESUS) é um grupo importante de pacientes com AVC criptogênico que estão em evidência devido a recentes ensaios clínicos. Foram revisados os prontuários médicos na alta da unidade de AVC de todos os pacientes que preencheram os critérios para ESUS atendidos em nossa instituição entre fevereiro de 2016 e julho de 2017. Entre 550 AVCs, 51 eram pacientes com ESUS. Hipertensão (60%), diabetes mellitus (34%) e tabagismo (36%) foram os fatores de risco mais prevalentes. Os escores médios do National Institutes of Health Stroke Scale (NIHSS) foram 7 na admissão e 4 na alta, enquanto os escores médios na escala de Rankin modificada (mRs) foram 0 e 2 na admissão e alta, respectivamente. Nossa amostra teve idade, prevalência de fatores de risco, escores NIHSS na admissão e alta, quando comparados com coortes europeias e norte-americanas semelhantes. Apesar de ser uma pequena coorte, nosso estudo sugere que a população ESUS é semelhante em países com diferentes níveis de financiamento em saúde.

ABSTRACT

ABSTRACT: The Catherine Bergego Scale (CBS) is a scale to evaluates the impact of unilateral spatial neglect (USN) on everyday life of patients after stroke. Objective: The aim of this study was to evaluate the reliability and comprehension of the Portuguese version of the CBS for patients with USN after stroke. Methods: This was a cross-sectional study in patients with stroke and USN. The CBS was translated, culturally adapted and applied by two independent investigators. The patients were also evaluated by the Behavioural Inattention Test (BIT), NIHSS, mRS and Barthel scale to assess USN severity, neurological function, disability and autonomy consecutively. Consistency and coherence were analysed using Cronbach's α, inter-observer reliability by Kappa, and the correlation between the CBS, BIT, NIHSS, mRS, and Barthel was determined using Pearson correlation. Results: Twenty-two patients were evaluated and the observed Cronbach's α=0.913. For intra-observer reproducibility, the 10 items showed a reasonable and high reliability between evaluators. The CBS showed a negative correlation with the BIT. There was a low correlation between the BIT and NIHSS, mRS and Barthel index. Conclusion: The CBS is an adequate and validated scale for assessing patients with USN after stroke in a Brazilian population.


RESUMO: A Escala de Catherine Bergego (CBS) é uma escala para avaliar o impacto da negligência espacial unilateral (USN) no cotidiano de pacientes após AVC. Objetivo: Não há validação da CBS para população brasileira e o objetivo deste estudo foi avaliar a confiabilidade e compreensão da versão em português da CBS para pacientes com USN após AVC. Métodos: Trata-se de um estudo transversal em pacientes com AVC e USN. A CBS foi traduzida, adaptada culturalmente e aplicada por dois investigadores independentes. Os pacientes também foram avaliados pelo Behaviour Innatention Test (BIT), NIHSS, mRS e Barthel para avaliar a gravidade da USN, função neurológica, incapacidade e autonomia consecutivamente. A consistência e a coerência foram analisadas pelo coeficiente α de Cronbach, a confiabilidade interobservador foi avaliada pelo coeficiente kappa e a correlação entre o CBS, BIT, NIHSS, mRS e Barthel foi avaliada pela correlação de Pearson. Resultados: Vinte e dois pacientes foram avaliados e observaram-se consistência e coerência pelo coeficiente α de Cronbach=0,913. Na análise da reprodutibilidade intraobservador, os 10 itens da escala apresentaram confiabilidade razoável e alta entre os avaliadores. O CBS mostrou correlação negativa com o BIT. Houve baixa correlação entre BIT e NIHSS, mRS e índice de Barthel. Conclusão: A CBS é uma escala adequada e validada para avaliar pacientes com USN após AVC em uma população brasileira e de língua portuguesa.

ABSTRACT

Hydrocephalus is a major concern in neurocysticercosis (NCC), and its management is more challenging than that of hydrocephalus caused by other etiologies. Even though albendazole is a well-established drug for the treatment of NCC, the death of the parasites may worsen the clinical symptoms and eventually, deteriorate the course of hydrocephalus. The aim of this study was to analyze the effects of treatment with albendazole on the course of hydrocephalus as well as on animal behavior in a ratmodel of NCC-induced hydrocephalus in order to verify whether the course of hydrocephalus and the animal behavior were changed. Ventricle volumes before and after treatment showed a slight but non-statistically significant difference (168.11 mm3 versus 184.98 mm3, p » 0.45). The distribution and location of the cysts were unaffected. In addition, the behavioral patterns before and after the treatment were not significantly different, as assessed by the open field test. On histologic assessment, mononuclear leukocyte infiltration was present in diverse sites, such as the perivascular and peri-ependymal regions, choroid plexus, and meningeal membranes. A positive correlation was found between the degree of ventricle enlargement and tissue damage. Further studies with long-term comparisons are required.
