Intracranial pressure waveform in patients with essential hypertension.

Background: There is a strong association between hypertension and cerebrovascular diseases, but most of the mechanistic bases to justify this correlation remains misunderstood. Objective: To evaluate intracranial pressure waveform in long-term essential hypertensive patients with a non-invasive device, brain4care (b4c). Methods: Cross-sectional study in patients with hypertension. Office blood pressure was measured with an automatic oscillometric device. Intracranial pressure evaluation was acquired through a strain sensor that could detect and monitor nanometric skull bone displacements for each cardiac cycle. Under normal physiological conditions, P1 is greater than P2, and the normal P2/P1 ratio is <1. Time to peak (TTP) is the measurement in seconds of the beginning of waveform inscription until P1 and normal values are <0.20 s. The cut-off points ≥1.2 and ≥0.25 s were used to define intracranial hypertension (ICHT). Results: 391 consecutive patients were evaluated (75% female, mean age 64.3 ± 12.0 years). Mean value of P2/P1 ratio was 1.18 ± 0.25 and TTP 0.18 ± 0.63 s The obtained P2/P1 ratios were divided in three categories according to results of previous studies of normalcy (<1.0), intracranial compliance disturbance (1.0-1.19) and ICHT (≥1.2). Normal intracranial pressure was observed in 21.7% of patients, intracranial compliance disturbance in 32.7% and intracranial hypertension in 45.6%. Females showed a higher prevalence of ICHT (50.3%). Conclusion: The prevalence of 45.6% intra-cranial hypertension in patients with long-term hypertension, particularly in women, and in those over 65 years old, emphasizes the importance of evaluate intracranial pressure behaviour in these patients and raise a question concerning the real ability of cerebral autoregulation and vascular barriers to protect the brain.

Moyamoya associated with Turner syndrome in a patient with type 2 spinocerebellar ataxia-Occam's razor or Hickam's dictum: a case report.

BACKGROUND: Turner syndrome (TS) is a rare condition associated with a completely or partially missing X chromosome that affects 1 in 2500 girls. TS increases the risk of autoimmune diseases, including Graves' disease (GD). Moyamoya disease is a rare cerebral arteriopathy of unknown etiology characterized by progressive bilateral stenosis of the internal carotid artery and its branches. Both TS and GD have been associated with Moyamoya. Type 2 spinocerebellar ataxia (SCA2) is an autosomal dominant cerebellar ataxia caused by a CAG repeat expansion in ATXN2. We present the first case of Moyamoya syndrome in a patient with a previous diagnosis of TS and GD who tested positive for SCA2 and had imaging findings compatible with an overlap of SCA2 and Moyamoya. CASE PRESENTATION: A 43-year-old woman presented with mild gait imbalance for 2 years. Her family history was positive for type 2 spinocerebellar ataxia (SCA2). She had been diagnosed with Turner Syndrome (45,X) and Graves disease three years before. Brain MRI revealed bilateral frontal and parietal cystic encephalomalacia in watershed zones, atrophy of pons, middle cerebellar peduncles and cerebellum. MR angiography showed progressive stenosis of both internal carotid arteries with lenticulostriate collaterals, suggestive of Moya-Moya disease. Molecular analysis confirmed the diagnosis of SCA2. CONCLUSIONS: With increased availability of tools for genetic diagnosis, physicians need to be aware of the possibility of a single patient presenting two or more rare diseases. This report underscores the modern dilemmas created by increasingly accurate imaging techniques and available and extensive genetic testing.

Social Isolation, Hospitalization, and Deaths from Cardiovascular Diseases during the COVID-19 Epidemic in São Paulo Metropolitan Area in 2020.

BACKGROUND: The COVID-19 epidemic overloaded the São Paulo metropolitan area (SPMA) health system in 2020. The leading hospitals directed their attention to patients with COVID-19. At the same time, the SPMA Health Secretary decreed social isolation (SI), which compromised the care for cardiovascular diseases (CVD), even though higher cardiovascular events were expected. METHODS: This study analyzed mortality from CVD, ischemic heart disease (IHD), and stroke, along with hospital admissions for CVD, IHD, stroke, and SI in the SPMA in 2020. Data regarding hospitalization and mortality from CVD were obtained from the SPMA Health Department, and data regarding SI was obtained from the São Paulo Intelligent Monitoring System. Time-series trends were analyzed by linear regression, as well as comparisons between these trends. RESULTS: there was an inverse correlation between SI and hospitalizations for CVD (R2 = 0.70; p < 0.001), IHD (R2 = 0.70; p < 0.001), and stroke (R2 = 0.39; p < 0.001). The most significant hospitalization reduction was from March to May, when the SI increased from 43.07% to 50.71%. The increase in SI was also associated with a reduction in CVD deaths (R2 = 0.49; p < 0.001), IHD (R2 = 0.50; p < 0.001), and stroke (R2 = 0.26; p < 0.001). CONCLUSIONS: Increased social isolation was associated with reduced hospitalizations and deaths from CVD, IHD, and stroke.

Resumo Introdução A doença cerebrovascular (DCBV) é a segunda principal causa de morte no mundo e no Brasil. Objetivo Avaliar as tendências da mortalidade por DCBV em duas cidades brasileiras (Maceió e Florianópolis) com diferenças socioeconômicas extremas, entre 1981 e 2015, estimando os efeitos idade, período e coorte. Método Estudo de séries temporais da mortalidade por DCBV em indivíduos com ≥ 40 anos, empregando a ferramenta Web tool. Resultados A mortalidade por DCBV diminuiu com o tempo, aumentou com a idade e foi menor para gerações mais novas. O efeito foi igual para ambos os sexos. Houve diminuição da mortalidade nas duas cidades, mas a diferença foi grande e a mortalidade continua alta em Maceió. Com base na amplitude dos efeitos estimados, foi possível verificar que o efeito de coorte foi o termo mais significativo para explicar a variabilidade temporal das taxas de mortalidade por DCBV no período. Conclusão A comparação da tendência temporal nas duas cidades mostrou a importância da melhora das condições de vida, do acesso a serviços de saúde para prevenção e controle dos fatores de risco, assim como assistência hospitalar aos casos para diminuirmos a mortalidade por DCBV em todo o território nacional.

Abstract Background Cerebrovascular disease (CBVD) is the second leading cause of death in the world and Brazil. Objective To evaluate trends in mortality from CBVD in two Brazilian cities (Maceió and Florianópolis) with extreme socioeconomic differences, between 1981 and 2016, estimating the age, cohort effect. Method Study of CBVD mortality time series in individuals aged ≥40 years, using the Age, Period, Cohort (APC) analysis and the Web tool. Results CBVD mortality decreased with time, increased with age and was lower for younger generations. The effect was the same for both sexes. There was a decrease in mortality in both cities, but the difference was large, and mortality remains high in Maceió. Based on the amplitude of the estimated effects, it was possible to verify that the cohort effect was the most significant term to explain the temporal variability of mortality rates due to CVD in the period. Conclusion The comparison of the time trend in the two cities showed the importance of improving living conditions, access to health services for the prevention and control of risk factors, as well as hospital care for cases to reduce mortality from CVD nationwide.

Assessment of Neurological Status in Patients with Cerebrovascular Diseases through the Nursing Outcome Classification: A Methodological Study.

Nurses play an important role in healthcare, and the Nursing Outcomes Classification is a key tool for the standardization of care. This study aims to validate the nursing outcome "Neurological Status" for patients with cerebrovascular diseases. A methodological study was performed in four phases. In Phase 1, the relevance of the indicators was evaluated by seven specialists and the modified kappa coefficient and content validity index were calculated. In Phase 2, conceptual and operational definitions were formulated. In addition, their content was validated with a focus group in Phase 3. In Phase 4, the results were applied in clinical practice and convergence with the National Institute of Health Stroke Scale was verified. The reliability was measured by Cronbach's alpha. Of the 22 initial indicators, 6 were excluded. The focus group suggested changes in the definitions and the exclusion of two indicators. In Phase 4, only 13 indicators were validated due to the impossibility of measuring intracranial pressure. A strong correlation between the two scales and agreement among all the indicators were observed. Following the specialists' review, the nursing outcome was reliable and clinically validated with 13 indicators: consciousness, orientation, language, central motor control, cranial sensory and motor function, spinal sensory and motor function, body temperature, blood pressure, heart rate, eye movement pattern, pupil size, pupil reactivity, and breathing pattern.

Concurrent validity and reliability of an activity monitoring for rehabilitation (AMoR) platform for step counting and sitting/lying time in post-stroke individuals.

BACKGROUND: Objective and reliable measurements to investigate daily behavior patterns in people with stroke could help therapeutic interventions after a stroke. OBJECTIVE: To evaluate whether the Activity Monitoring for Rehabilitation (AMoR) platform has adequate concurrent validity and reliability for step counting and time spent sitting/lying in people post-stroke and to investigate its percentage accuracy for step counting at different walking speeds. METHODS: Cross-sectional observational study. Fifty chronic post-stroke subjects used the AMoR platform and SAM simultaneously while a Video camera recorded the same activities during clinical trials. Spearman's correlation coefficient, the mean absolute percentage error, the intraclass correlation coefficient and Bland-Altman plot analyses were used to estimate the validity and reliability of the AMoR platform and StepWatchTM Activity Monitor (SAM). The accuracy percentage was calculated for each device and plotted as a function of the walking speed during the 10-meter walk test (10MWT). RESULTS: There was a very high correlation for step counting in all tests and a high correlation for time spent sitting/lying. The mean absolute percentage error values remained below 4% for step counting and time sitting/lying. The AMoR platform also showed excellent reliability for step counting and sitting/lying time, with values within the limit of agreement in the Bland-Altman plots. A high percentage of accuracy for step counting in the AMoR platform was observed during the 10MWT. CONCLUSION: The AMoR platform is valid and reliable for step counting and time spent sitting/lying, with a high percentage of accuracy at different walking speeds in the post-stroke population.

Tendência da mortalidade das doenças cardiovasculares, nas capitais brasileiras, no período entre 1990 e 2018 / Trends in mortality from cardiovascular diseases in brazilian capitals between 1990 and 2018

As doenças cardiovasculares (DCV) são a principal causa de morte no Brasil e no mundo. As doenças isquêmicas do coração (DIC) e doenças cerebrovasculares (DCBV) estão entre as dez principais causas de mortes no Brasil. A análise de tendência da mortalidade por DCV permite definir populações prioritárias para intervenções, elaborar e avaliar ações em saúde pública. Nesse sentido, o objetivo do estudo foi analisar a tendência da mortalidade por DIC e DCBV nas 27 capitais brasileiras, no período de 1990 a 2018. Trata-se de um estudo ecológico de série temporal, os dados de óbitos foram obtidos através do Sistema de Informações sobre Mortalidade (SIM). Buscando corrigir problemas na qualidade da informação dos registros de óbito do SIM, realizou-se a correção dos óbitos referentes aos dados com sexo e/ou faixa etária ignorada e aos óbitos registrados com causas "mal definidas". As taxas de mortalidade por DIC e DBCV foram padronizadas pelo método direto, tomando-se como população padrão a população do Brasil no ano de 2010. A análise de tendência da mortalidade por DIC e DCBV para a população total, homens e mulheres foi realizada utilizando o modelo de regressão de Poisson. Os resultados mostraram tendência de redução da mortalidade por DCBV tanto para a população total como para homens e mulheres em todas as capitais brasileiras. Vitória, capital da região Sudeste, apresentou a maior redução da taxa de mortalidade total por DCBV dentre todas as capitais brasileiras, -5,6% ao ano (IC95%: -6,0; -5,1%). No entanto, Macapá, capital da região Norte, teve a menor dentre todas as capitais -1,7% ao ano (IC95%: -2,7; -0,7%). Paras as DIC foi observada tendência de redução da mortalidade tanto para a população total como para homens e mulheres nas capitais das regiões Sul, Sudeste e para a maioria das capitais da região Centro-Oeste. As capitais das regiões Norte e Nordeste apresentaram uma variabilidade na tendência da mortalidade por DIC. Conclui-se que as capitais das regiões Sul e Sudeste apresentaram as maiores reduções da tendência da mortalidade por DIC e DCBV. Os achados desse estudo são importantes para prover informações mais detalhadas buscando auxiliar a gestão local na promoção de políticas de saúde pública, planejamento de estratégias e elaboração de medidas e ações em saúde.

Cardiovascular diseases (CVD) are the leading cause of death in Brazil and worldwide. Ischemic heart diseases (IHD) and cerebrovascular diseases (CBVD) are among Brazil's ten main causes of death. The trend analysis of mortality from CVD allows defining priority populations for interventions, designing and evaluating public health actions. In this sense, the study's objective was to analyze the mortality trend from IHD and CBVD in the 27 Brazilian capitals from 1990 to 2018. This is an ecological time-series study with the Mortality Information System (SIM) data. Seeking to correct the quality of the information in the SIM death records, the correction of deaths referring to data with anonymous sex and age group and deaths recorded with "ill-defined" causes was carried out. IHD and CBVD mortality rates were standardized by the direct method, using the population of Brazil in 2010 as the standard population. Trend analysis of IHD and CBVD mortality for the total population, men and women, was performed using the Poisson regression model. The results showed a reduction in the trend of mortality from CBVD for both the total population and for men and women in all Brazilian capitals. Vitória, the capital of the Southeast region, showed the greatest reduction in the total mortality rate from CVD among all Brazilian capitals, -5.6% per year (95%CI: -6.0; -5.1%). However, Macapá, the capital of the North region, had the lowest among all capitals -1.7% per year (95%CI: -2.7; -0.7%). For IHD, a decrease in the mortality trend was observed both for the total population and for men and women in the capitals of the South and Southeast regions and most capitals of the Center-West region. The capitals of the North and Northeast regions showed variability in the trend of IHD mortality. In conclusion, the capitals of the South and Southeast regions showed the greatest reductions in the mortality trend due to IHD and CBVD. The findings of this study are essential to provide more detailed information to assist local management in promoting public health policies, planning strategies, and designing health measures and actions.

Tendências Recentes de Mortalidade Cardiovascular nas Regiões de Saúde do Estado do Rio de Janeiro e Capital / Recent Trends in Cardiovascular Mortality in Rio de Janeiro State Health Regions and Capital

Resumo Fundamento: A mortalidade por doenças cardiovasculares (DCV) vem mostrando tendência à estabilização em alguns países, incluindo o Brasil e o estado do Rio de Janeiro, após décadas de queda. Não encontramos análises detalhadas dessa tendência para o estado do Rio de Janeiro. Objetivo: Analisar as tendências da mortalidade prematura e tardia por doenças do aparelho circulatório (DAC), doença isquêmica do coração (DIC) e doença cerebrovascular (DCBV) por sexo nas regiões de saúde do estado do Rio de Janeiro e capital (1996-2016). Métodos: Dados de óbitos e população foram obtidos no DATASUS/MS. Taxas foram compensadas por códigos mal definidos, corrigidos pelos códigos cardiovasculares mal definidos e ajustadas por sexo e idade pelo método direto. O Joinpoint Trend Analysis Software foi empregado para calcular a variação percentual anual (APC) e variação percentual anual média (AAPC). Foram consideradas para o estudo APC e AAPC significativamente diferentes de zero, calculadas por um teste de student com significância de 5%. Resultados: A mortalidade por DIC estabilizou ou até aumentou em pelo menos 50% das localidades analisadas (EAPC ≥0). Nas regiões Norte e Noroeste, nenhuma mudança foi observada. Para DCBV, apenas uma região apresentou estabilidade na mortalidade (EAPC próximo a 0). Para as outras regiões, a taxa continuou a diminuir (APC <0) até 2016. Conclusão: Esses resultados observados no Rio de Janeiro devem se repetir em várias regiões brasileiras e apontam para a necessidade de uma resposta na abordagem dos comportamentos no estilo de vida. Os médicos da atenção primária devem estar familiarizados com a tendência desfavorável da doença isquêmica do coração entre os adultos mais jovens e rastrear ativamente os fatores de risco para DCV, com atenção especial às mulheres.

Abstract Background: Cardiovascular disease (CVD) mortality, after several decades of decrease, has shown a tendency towards the stabilization in some countries, including Brazil and Rio de Janeiro state. This new tendency was not further analyzed by gender, age group and region of the Rio de Janeiro state. Objective: To analyze the trends of premature and late mortality from CVD, ischemic heart disease (IHD) and cerebrovascular disease (CBVD) by gender in the city of Rio de Janeiro (capital) and the health regions of Rio de Janeiro state (from 1996 to 2016. Methods: Data on deaths and the population were obtained from DATASUS/MS. The rates were compensated by ill-defined codes, corrected by Ill-Defined Cardiovascular codes and gender and age-adjusted by the direct method (reference population - population of the state of Rio de Janeiro - 2000 census). The Joinpoint Trend Analysis Software was employed. Results: IHD mortality stabilized or even increased for at least 50% of the analyzed areas (EAPC≥0). No change was observed. in the "North" and "Northwest" regions For CBVD, just one region showed stability regarding mortality (EAPC close to 0). For the other regions, the rate continued to decrease (APC<0) until 2016. Conclusion: These results observed in Rio de Janeiro are possibly appropriate to various Brazilian regions and demonstrate that a serious public health response is needed to address lifestyle behaviors. Primary care physicians should also be familiar with the unfavorable tendency in coronary heart disease among younger adults in recent years and actively screen for risk factors for cardiovascular disease, paying special attention to women.

Infección por COVID-19 y accidente cerebrovascular / COVID-19 Infection and Stroke

La actual pandemia de COVID-19 causada por el virus SARS-CoV-2, se caracteriza por una alta morbilidad y mortalidad. Algunos estudios han reportado que la frecuencia de ictus en pacientes infectados con el virus oscila entre un 5-20 por ciento. A pesar de estas cifras alarmantes, las vías por las cuales el virus llega al sistema nervioso central y los mecanismos fisiopatológicos por los que puede ocurrir un ictus en estos pacientes no han sido totalmente esclarecidos. Numerosos estudios han demostrado que la infección por SARS-CoV-2 está asociada a un estado protrombótico, capaz de causar un tromboembolismo arterial y venoso. Además, se ha reportado una respuesta inflamatoria exacerbada, con reclutamiento de células sanguíneas y una secreción desproporcionada de citoquinas proinflamatorias. También la hipoxia y fenómenos cardioembólicos han sido propuestos como posibles mecanismos. Es esencial definir con exactitud los mecanismos fisiopatológicos que vincula la infección por SARS-CoV-2 con la ocurrencia del ictus, con la finalidad de aplicar tratamientos más específicos y evitar futuras complicaciones(AU)

The actual Coronavirus Disease 2019 (COVID-19) infection is an ongoing pandemic, characterized by high morbidity and mortality produced by SARS-CoV-2 virus. Studies reported a stroke frequency around 5-20 percent in infected patients; however, SNC invasion and pathophysiological mechanisms related to stroke in COVID-19 patients are still unknown. Several studies have demonstrated that SARS-CoV-2 infection is linked to a prothrombotic state causing venous and arterial thromboembolism. Also, an overstated inflammatory response with recruitment of blood cells and disproportioned secretion of proinflammatory cytokines has been reported. Finally, cardioembolism and hypoxia have been proposed as surrogate mechanisms. It is essential to define the pathophysiological mechanisms of stroke during the infection in order to apply more specific treatments to avoid further stroke complications(AU)

Renin-Angiotensin System in Central Nervous System Diseases and its Interaction with COVID-19.

BACKGROUND: The Renin-Angiotensin System (RAS) comprises a complex molecular cascade with two counter-regulatory axes, the classical and the alternative. Angiotensin II and Angiotensin-(1-7), the main peptides of the RAS, exert opposite effects in multiple organs and systems, including the cardiovascular, renal, pulmonary, and immune systems. Strong evidence supports the hypothesis of a local RAS in the Central Nervous System (CNS) and its modulatory roles in neuroendocrinology and neurotransmission. OBJECTIVE: In this narrative review, we provide a comprehensive approach to experimental and clinical data regarding RAS molecule expression and their possible roles in the physiology and physiopathology of CNS diseases. METHODS: This non-systematic review summarizes evidence on RAS implications in CNS diseases and their possible relationships with COVID-19. RESULTS: We divided the possible RAS mechanisms in distinct conditions during the lifespan, approaching from congenital infections to neurodegenerative alterations, passing through mood disorders and cerebrovascular diseases. We also gathered current evidence about the possible effects of RAS in Covid-19, particularly in cases with neurological manifestations. CONCLUSION: Although there are limitations and controversies, the analysis of RAS mechanisms in the CNS certainly represents an interesting field of research. However, further investigation is necessary to support the noteworthy interactions and provide a better comprehension of the cross-talk between RAS and the CNS. Investigations in this research field may shed light on the novel therapeutic targets.

Dashboard and a Model of Predictive Analysis for Cerebrovascular Diseases in Primary Health Care.

Cerebrovascular and hypertensive diseases are among the leading causes of death in the world. This study was developed in two stages: the development of a dashboard with specific reports of cerebrovascular diseases and applied a preliminary predictive analysis model for cerebrovascular diseases. The results demonstrate the abitity to predict a citizen's chance acquiring a cerebrovascular disease.

Infográficos para decisão compartilhada no uso de estatinas em paciente de alto risco cardiovascular / Infographic for shared-decision for statins use in patients with high cardiovascular risk / Infográficos para decisión compartida en pacientes con alto riesgo cardiovascular

Objetivos: Elaborar infográficos para decisão compartilhada sobre o benefício e risco do uso de estatinas como prevenção primária em pacientes com alto risco cardiovascular. Métodos: A partir do "the NNT", que analisou o uso de estatinas para prevenção primária em pessoas de baixo risco cardiovascular a partir de meta-análises do US Preventive Services Task Force (USPSTF) e da Cochrane, buscou-se definir o balanço de risco e benefício dessa terapia na prevenção primária de pessoas com alto risco. Como o USPSTF e a Cochrane tinham 10 estudos primários diferentes incluídos em suas análises e populações com risco cardiovascular variável, foi realizada uma busca adicional por revisões sistemáticas e meta-análises publicadas desde a data da revisão Cochrane (dezembro de 2012) até outubro de 2017. Buscou-se no Medline via PubMed, na Biblioteca Virtual em Saúde, na Cochrane e no NHS Evidence por estudos de pessoas com risco cardiovascular estimado em 10 anos de mais de 10% com mais um fator de risco ou com mais de 20%, sem história de doença cardiovascular prévia, que comparassem o uso de estatina com placebo ou nenhum tratamento. Os desfechos deveriam ser a redução de doenças cardio e cerebrovasculares, da mortalidade cardiovascular ou geral e a ocorrência de eventos adversos. Resultados: Foram encontrados 225 estudos entre meta-análises e revisões sistemáticas elaboradas desde dezembro de 2012 até outubro de 2017. Foram excluídos 224 estudos por motivos diversos. Selecionou-se para elaboração do infográfico de benefícios o Statins for primary prevention, 2012, com população de 100% de diabéticos sem eventos cardiovasculares prévios com redução de risco absoluto (RRA) quanto a AVC fatal de 0,78 pontos percentuais/NNT 128 e Doenças Cardio/Cerebrovasculares RRA 2,6 pontos percentuais/NNT 39, cardiovascular. Quanto à redução de mortalidade geral (RR 0,79; IC95% 0,58-1,08) e revascularização (RR 0,74; IC 95% 0,55-1,00) não foi encontrada diferença estatística significante. Devido às limitações encontradas nas revisões sistemáticas avaliadas, não foi possível compilar dados, no formato de infográfico, sobre a incidência de diabetes e abandono de terapia. Assim, para elaboração da parte referente a danos, foi selecionado o ECR Aspen, com população de diabéticos de alto risco para desenvolvimento de eventos cardiovasculares, sem eventos prévios, quanto à mialgia com aumento do risco absoluto (ARA) de 1,43 pontos percentuais/NND 70 (RR 1,91; IC95% 1,03-3,53). Conclusão: Foi elaborado infográfico, com e sem uso de estatina, para desfechos cardiocerebrovasculares não fatais, AVC fatal, necessidade de revascularização, mortalidade geral e para ocorrência adversa de sintomas musculares. Esse instrumento pode ser utilizado na Atenção Primária durante o encontro clínico visando à tomada de decisão compartilhada, facilitando a compreensão dos riscos e benefícios do uso de estatina em pacientes de alto risco cardiovascular (RCV 10% com pelo menos um fator de risco adicional ou > 20 % em 10 anos), diabéticos, nos quais a prescrição de estatina seja cogitada
