Avaliação da influência dos marcadores inflamatórios na mortalidade de pacientes com AVC isquêmico / Evaluation of the influence of inflammatory markers on the mortality of patients with ischemic stroke

INTRODUÇÃO: À medida que a população envelhece e a expectativa de vida aumenta, a incidência global e a prevalência de AVC isquêmico tendem a aumentar significativamente. Nesse contexto, surge a necessidade de avaliar novos marcadores preditores de mortalidade, como a contagem absoluta de monócitos, relação linfócitos sobre monócitos, relação neutrófilos sobre linfócitos e níveis de proteína C reativa ultrassensível, que além de serem de fácil acesso e baixo custo, sugerem indicar desfecho no paciente com AVC agudo. OBJETIVOS: o objetivo deste estudo foi avaliar a associação dos marcadores inflamatórios com a mortalidade de pacientes com AVC isquêmico. MÉTODOS: trata-se de um estudo retrospectivo observacional a partir de prontuários eletrônicos e exames laboratoriais de pacientes com AVC isquêmico em uma unidade hospitalar de Cascavel/PR. Uma análise estatística descritiva foi conduzida para determinar o perfil dos pacientes segundo o desfecho e aplicado um modelo de regressão logística para verificar as variáveis associadas a mortalidade. Foram considerados significativos apenas os dados com p-valor <0,05. RESULTADOS: Dos 65 pacientes que foram admitidos no estudo, 50 receberam alta hospitalar e 15 foram a óbito no hospital. Entre os marcadores inflamatórios, a relação de neutrófilos sobre linfócitos (OR 1,55; p-valor <0,01) mostrou-se significativamente associada a maior chance de óbito. Os pacientes que faleceram apresentaram níveis superiores de PCR ultrassensível, maior contagem absoluta de monócitos, relação linfócitos sobre monócitos diminuída, e relação neutrófilos sobre linfócitos elevada. CONCLUSÃO: a relação de neutrófilos sobre linfócitos elevada pode estar significativamente associada ao desfecho desfavorável após um AVC isquêmico

IINTRODUCTION: As the population ages and life expectancy increases, the global incidence and prevalence of ischemic stroke tends to rise significantly. In this context, the need arises to evaluate new predictive markers of mortality, such as absolute monocyte count, lymphocyte-to-monocyte ratio, neutrophil-to-lymphocyte ratio and C-reactive protein (CRP) levels which, besides being easily accessible and affordable, manage to predict the outcome in patients with acute stroke. OBJECTIVES: the aim of this study was to evaluate the association between inflammatory markers and the mortality in ischemic stroke patients. METHODS: this is a retrospective observational study based on the analysis of electronic medical records and laboratory tests of in-patients who suffered an ischemic stroke in Cascavel/PR. A descriptive statistical analysis was conducted to determine patients´ profile according to the outcome and a logistic regression model was applied in order to verify the variables associated with mortality. Only data with a p-value <0,05 was considered. RESULTS: Out of the 65 patients who suffered an ischemic stroke included in the study, 50 were discharged and 15 died in hospital. Among the inflammatory markers, the neutrophil-tolymphocyte ratio (OR 1.55; p-value <0,01) was associated with a greater chance of death. Patients who died presented with higher levels of ultra-sensitive CRP, higher absolute monocyte count, lower lymphocyte-to-monocyte ratio and higher neutrophil-to- lymphocyte ratio. CONCLUSION: the elevated neutrophil-to-lymphocyte ratio may be significantly associated with negative outcomes following an ischemic stroke

Factores de riesgo y causas de ACV isquémico en pacientes jóvenes (18-49 años) en Colombia: una revisión sistemática / Risk factors and causes of ischemic stroke in young patients (18-49 years) in Colombia: a systematic review

INTRODUCCIÓN: El ataque cerebrovascular (ACV) es la principal causa de discapacidad en el mundo. Su incidencia está en aumento, incluso en jóvenes. Por lo anterior, los factores de riesgo y etiologías diversas del ACV en jóvenes deben estudiarse para planear acciones preventivas. Por eso en Colombia es necesario conocer dichos factores y etiologías analizando los estudios sobre el tema. METODOLOGÍA: Se hizo búsqueda y análisis de artículos sobre causas y factores de riesgo de ACV isquémico en Colombia publicados en Pubmed, Lilacs, Scielo, Google Scholar. Luego de revisar títulos y resúmenes se excluyeron los que no se referían a jóvenes entre 18 y 49 años o ACV isquémico, revisiones de tema, duplicados. Finalmente se analizaron 20 artículos. RESULTADOS Y DISCUSIÓN: La mayor parte de los estudios eran reporte o series de casos, sumaron 60 personas. No hubo predominio de sexo, excepto en los casos de síndrome antifosfolípido (SAF) que fueron mujeres, a diferencia de la mayoría de las series mundiales. La mayor frecuencia fue 56% para otras causas determinadas como SAF y disección de vasos craneocervicales, superior a otros reportes. Hubo una frecuencia baja de enfermedad de gran vaso, similar a otros estudios. La enfermedad de pequeño vaso fue mayor a otros reportes en Latinoamérica. CONCLUSIONES: La mayor parte de la información provino de reportes y series de caso que podrían no reflejar la frecuencia real de causas y factores de riesgo. Merece atención la neurocisticercosis y sustancias psicoactivas como causas de ACV propias de la revisión en colombiana.

INTRODUCTION: Stroke is the leading cause of disability in the world. Its incidence is increasing, even in young people. Therefore, the risk factors and various etiologies of stroke in young people should be studied to plan preventive actions. That is why in Colombia it is necessary to know these factors and etiologies analyzing the studies on the subject. METHODS: Search and analysis of articles on causes and risk factors of ischemic stroke in Colombia published in Pubmed, Lilacs, Scielo, Google Scholar. After reviewing titles and abstracts, those that did not refer to young people between 18 and 49 years, reviews, did not refer to ischemic strokes, duplicates, were excluded. Finally, 20 articles were analyzed. RESULTS AND DISCUSSION: Most of the studies were report or case series, they added 60 people. There was no predominance of sex, except in the cases of antiphospholipid síndrome (APS) that were women, unlike most of the world series. The highest frequency was 56% for other determined causes such as APS and craniocervical vessel dissection, higher than other reports. There was a low frequency of large vessel disease, similar to other studies. Small vessel disease was higher than other reports in Latin America. CONCLUSIONS: Most of the information came from reports and case series that may not reflect the real frequency of causes and risk factors. Neurocysticercosis and psychoactive substances as causes of stroke proper of the review in Colombia deserve attention.

Alterações cardiorrespiratórias em indivíduos hemiparéticos crônicos pós-acidente vascular cerebral / Cardiorespiratory changes in chronic post-stroke hemiparetic patients

Objetivo: Analisar a função cardiorrespiratória em pacientes he- miparéticos crônicos pós-acidente vascular cerebral. Métodos: Estudo retrospectivo, por meio da análise de dados de prontuários de pacientes submetidos ao teste de caminhada de 6 minutos e manovacuometria em uma clínica de fisioterapia de um centro universitário. Foram analisados os dados de sete prontuários. Re- sultados: A média de metros percorridos pelos participantes no teste de caminhada de 6 minutos foi de 199,5. Os valores percentuais da manovacuometria foram de -41,34 na pressão inspiratória máxima e de 57,85 na pressão expiratória máxima. Conclusão: Os dados desta pesquisa sugerem que indivíduos hemiparéticos crônicos apresentam fadiga respiratória e muscular, diminuição da capacidade funcional durante a marcha e fraqueza dos músculos respiratórios.

Objective: To analyze the cardiorespiratory function in chronic post-stroke hemiparetic patients. Methods: This is a retrospective study, through data analysis of medical records from patients who underwent the 6-minute walk test and manovacuometry, in a physical therapy clinic of a university center. Results: The mean number of meters walked by participants in the 6-minut walk test was 199.5 meters. The percentage values of manovacuometry were -41,34 in the maximun inspiratory pressure and 57.85 in the maximun expiratory pressure. Conclusion: The data from this survey suggest that chronic hemiparetic individuals have respiratory and muscle fatigue, decreased functional capacity during gait, and respiratory muscle weakness.

Caracterización de pacientes con accidente cerebrovascular en un servicio de emergencias de Santiago de Cuba / Characterization of patients with stroke in an emergency service from Santiago de Cuba

Introducción: El accidente cerebrovascular es el daño neurológico que ocurre cuando uno de los vasos sanguíneos del cerebro se obstruye por un coágulo (embolia o trombo) o se rompe (hemorragia), lo cual no permite el flujo sanguíneo cerebral. Objetivo: Caracterizar a los pacientes con accidente cerebrovascular atendidos en el Servicio de Emergencias del Hospital Clinicoquirúrgico Docente Dr. Joaquín Castillo Duany de Santiago de Cuba. Métodos: Se realizó un estudio descriptivo y transversal de 122 pacientes con accidente cerebrovascular atendidos en el mencionado Servicio desde octubre de 2016 hasta igual mes de 2017. Se tuvieron en cuenta variables de interés demográficas relacionadas con la enfermedad y se utilizó el porcentaje como medida resumen. Resultados: En la serie predominaron el sexo femenino (58,2 %) y el grupo etario de 61-70 años. Se comprobó que 26,2 % de los afectados permanecieron más de 6 horas en el Servicio de Emergencias y se encontró una asociación de esta enfermedad con la hipertensión arterial, la diabetes mellitus, la cardiopatía isquémica, el hábito de fumar, el alcoholismo y la hiperlipidemia; igualmente, el uso inadecuado del tratamiento farmacológico y de la ventilación mecánica artificial ocasionó una tasa de letalidad elevada. Conclusiones: A pesar de los estudios realizados en esta misma institución, se impone continuar profundizando en el adecuado control y seguimiento de dichos accidentes, así como también desarrollar estrategias que permitan la superación y preparación del personal médico y paramédico de ese centro hospitalario.

Introduction: The stroke is the neurological damage that happens when one of the brain blood vessels is obstructed by a clot (embolism or clot) or it breaks (hemorrhages), which doesn't allow the brain blood flow. Objective: To characterize the patients with stroke assisted in the Emergencies Service of Dr. Joaquín Castillo Duany Teaching Clinical Surgical Hospital in Santiago de Cuba. Methods: A descriptive and cross-sectional study of 122 patients with stroke assisted in the mentioned Service from October, 2016 to the same month in 2017 was carried out. Demographic variables of interest related to the disease were taken into account and the percentage as summary measure was used. Results: The female sex (58.2 %) and 61-70 age group prevailed in the series. It was demonstrated that 26.2 % of those affected stayed more than 6 hours in the Emergencies Service and it was found an association of this disease with hypertension, diabetes mellitus, ischemic heart disease, nicotine addiction, alcoholism and hyperlipemia; equally, the inadequate use of the pharmacological treatment and the mechanic artificial ventilation caused a high lethality rate. Conclusions: In spite of the studies carried out in this same institution, it is important to continue deepening in the appropriate control and follow up of these accidents, as well as to develop strategies that allow training and preparation of the medical and paramedic staff of that hospital.
