Introducción: La enfermedad cerebrovascular es la tercera causa de muerte en el mundo y representa la causa más frecuente de discapacidad permanente en adultos. Objetivo: Determinar los factores de riesgo asociados a enfermedades cerebrovasculares en mujeres. Métodos: Se realizó un estudio analítico observacional, de tipo caso-control, a partir de 35 pacientes del sexo femenino con diagnóstico de enfermedad cerebrovascular (casos) y otro grupo de pacientes que no presentaban dicha enfermedad (controles). Se utilizó el porcentaje como medida resumen de las variables cualitativas. Se determinó la razón de productos cruzados, el intervalo de confianza y la prueba de ji al cuadrado, así como el riesgo atribuible en expuesto porcentual para identificar los factores que se asociaron a la presencia de la enfermedad. Resultados: La hipercolesterolemia, la obesidad, el sedentarismo, los hábitos nutricionales inadecuados y el uso de anticonceptivos orales fueron los factores de riesgo modificable más significativos, con valores de razón de productos cruzados de 10,15; 9,08 y 8,17 y un riesgo atribuible en expuesto de 90,1 %, 89 %; 87,8 % respectivamente. Por otra parte, la enfermedad cardíaca, la hipertensión arterial y la enfermedad cerebrovascular previa fueron los padecimientos asociados de mayor significación con razón de productos cruzados en expuesto de 3,55 y 2,97 y un riesgo atribuible en expuesto de 71,8 y 66,3 %, respectivamente. Conclusiones: Los factores de riesgos modificables como hipercolesterolemia, obesidad, sedentarismo, hábitos nutricionales inadecuados y el uso de métodos anticonceptivos aumentaron la probabilidad de sufrir enfermedad cerebrovascular en las mujeres estudiadas.

Introduction: Cerebrovascular disease is the third cause of death in the world, representing the most frequent cause of permanent disability in adults. Objective: To determine the risk factors associated with cerebrovascular diseases in women. Methods: A case-control observational analytical study was carried out in 35 female patients diagnosed with cerebrovascular disease (cases) and another group of patients who did not have said condition (controls). The percentage was used as a summary measure of the qualitative variables. The ratio of cross products, the confidence interval and the chi-square test were determined, as well as the attributable risk in percentage exposed to identify the factors that were associated with the presence of the disease. Results: Hypercholesterolemia, obesity, a sedentary lifestyle, inadequate nutritional habits, and the use of oral contraceptives were the most significant modifiable risk factors, with cross-product ratio values of 10.15, 9.08, and 8.17 and attributable risk in exposed of 90.1%, 89%, 87.8% respectively. On the other hand, heart disease, hypertension and previous cerebrovascular disease were the most significant associated conditions with a ratio of cross products in exposed of 3.55 and 2.97 and attributable risk in exposed of 71.8 and 66.3%, respectively. Conclusions: Modifiable risk factors such as hypercholesterolemia, obesity, sedentary lifestyle, inadequate nutritional habits and the use of contraceptive methods increased the probability of suffering cerebrovascular disease in the women studied.

The ontogenetic model for CVA rehabilitation with transcranial stimulation

Currently, transcranial stimulation for CVA treatment is based on the interhemispheric rivalry model. This model has proven to have many anomalies, necessitating a new paradigm. Spontaneous recovery from post-CVA hemiplegia has an ontogenetic pattern. We reanalyzed the 2008 longitudinal London study and found that cortical disinhibition is the mechanism for ontogenetic CVA recovery. We propose that transcranial stimulation with 10 Hz rTMS or anode electrical microstimulation can produce CVA recovery similar to spontaneous recovery. (Acta Med Colomb 2022; 47. DOI:https://doi.org/10.36104/amc.2022.2466).

Actualmente la aplicación de la estimulación transcraneal para el tratamiento del ACV se realiza con base en el modelo de rivalidad interhemisférica. Este modelo ha mostrado muchas anomalías que hacen necesario un nuevo paradigma. La recuperación espontánea de la hemiplejia post-ACV tiene patrón ontogénico. Reanalizamos el estudio longitudinal de Londres 2008 y encontramos que su propuesta corresponde al mecanismo de recuperación ontogénica del ACV. Planteamos que la estimulación transcraneal, utilizando EMTr a 10 Hz o microestimulación eléctrica anódica, podría recuperar el ACV de manera similar a la recuperación espontánea.

Validity evidence for the Cognitive Screening test in stroke patients / Evidências de validade para o instrumento Triagem Cognitiva em pacientes com acidente vascular cerebral / Evidencias de validez del instrumento de Cribado de Deterioro Cognitivo en pacientes con accidente cerebrovascular

Cognitive deficits are common among post-stroke patients. Cognitive impairments of this sort are mediated by age and education. In Brazil, the only specific cognitive screening tool designed for post-stroke patients is the Cognitive Screening Test (Triagem Cognitiva - TRIACOG). The goal of this study was to investigate validity evidence related to external variables for the TRIACOG. Our sample included 153 adults and elderly people (M = 60.08, SD = 9.61) from Porto Alegre and metropolitan area, comprising 87 post-stroke patients and 66 healthy individuals. Three-way ANOVAs were used to assess main effects and interactions between the variables group (clinical/control), age and education. An influence of group and age on scores in the TRIACOG was found. We emphasize the relevance of these results to the selection of cut-off points for the tasks and cognitive functions assessed by the instrument, considering education and age, so as to allow more accurate identification of deficits in post-stroke patients.

Nonvalvular atrial fibrillation in anticoagulated patients

Objective: to analyze the epidemiological and clinical characteristics of a population with nonvalvular atrial fibrillation (NVAF) treated with oral anticoagulation at Instituto Cardiovascular del Tolima in Ibagué, Colombia. Reference framework: NVAF is a prevalent disease in Colombian patients over the age of 60, who are at greater risk of a cerebrovascular accident, which is preventable with anticoagulation treatment. However, complications inherent or secondary to the disease may occur despite treatment. Methods: a cross-sectional study which describes the baseline characteristics of a total of 146 participants with NVAF being treated with oral anticoagulants, using information from their clinical charts between 2018 and 2019. Results: of the participants, 53% were female, and 57% of the participants had permanent NVAF, this being the most frequent type in the study cohort. Ninety-nine percent were treated with non-vitamin K oral anticoagulants (NOACs) (76% with rivaroxaban), and 1% with a VKA (warfarin). Eighty-nine percent of the participants had a CHADS2 classification between 1-3 and 87% fell in the HASBLED 1-3 categories; of these, 95% did not have a CVA/TIA, 99% did not have a systemic embolism and 97% did not have major bleeds, respectively for each classification. There were no fatal outcomes in any of the patients. Conclusions: an association was confirmed between CHADS2, CHADS2VASC2 and HASBLED classifications and CVA/TIA and hemorrhages in the study population (p<0.05). (Acta Med Colomb 2022; 47. DOI:https://doi.org/10.36104/amc.2022.2202).

Simultaneous thromboses in patients with SARS-CoV-2 infection

COVID-19 infection has a high morbidity and mortality rate. Although there is mainly pulmonary involvement, SARS-CoV-2 infection is considered to be a true endothelial disease, given these patients' increased risk of developing both arterial and venous thrombotic phenomena. We present three cases of patients with active SARS-CoV-2 infection and simultaneous thromboses in different vascular territories: cerebrovascular disease and pulmonary embolism, cerebrovascular disease and peripheral arterial embolism, and cerebrovascular disease plus deep vein thrombosis. We emphasize the scant evidence on the topic in the current literature and the importance of being alert to the onset of these events during the clinical course of patients with acute infection with the new coronavirus. (Acta Med Colomb 2022; 47. DOI:https://doi.org/10.36104/amc.2022.2347).

La infección por COVID-19 tiene una alta tasa de morbimortalidad, si bien existe principalmente compromiso pulmonar, se considera que la infección por SARS-CoV-2 es una verdadera endoteliopatía, dado el riesgo aumentado que tienen estos pacientes de desarrollar fenómenos trombóticos como arteriales y venosos. Presentamos tres casos de pacientes con infección activa por SARS-CoV-2 y trombosis simultáneas en diferentes territorios vasculares: enfermedad cerebrovascular y embolismo pulmonar, enfermedad cerebrovascular y embolismo arterial periférico, enfermedad cerebrovascular más trombosis venosa profunda. Enfatizamos en la poca evidencia de la literatura actual al respecto y la importancia de estar atentos al desarrollo de estos eventos durante la evolución de los pacientes con infección aguda por nuevo coronavirus.

Awareness towards stroke among high school students in Brazil: a cross-sectional study

ABSTRACT BACKGROUND: Stroke is one of the main causes of death worldwide. Educational interventions on stroke are potentially effective in reducing the period between the onset of symptoms and the initial emergency medical assistance. OBJECTIVES: To assess high school students' knowledge of stroke. DESIGN AND SETTING: Cross-sectional study conducted in high schools in northeastern Brazil. METHODS: A self-structured questionnaire survey regarding stroke awareness was applied among high school students in northeastern Brazil. Data were collected between 2018 and 2019. The chi-square test and other descriptive statistics were used. Univariate and multivariate analyses were performed using logistic regression. RESULTS: A total of 1,788 students were analyzed. Eighty percent (n = 1430) of them did not have the minimum knowledge on how to act in a stroke situation. Only 10% (n = 179) presented the ideal knowledge on how to act. Males presented lower levels of knowledge on risk factors (odds ratio, OR: 0.62%; 95% confidence interval, CI: 0.49-0.79) and signs and symptoms of stroke (OR: 0.63%; 95% CI: 0.52-0.77). Students with ≥ 10 years of schooling (OR: 1.64%; 95% CI: 1.30-2.07) demonstrated greater knowledge of signs and symptoms of stroke. Students aged 18 years (OR: 1.70%; 95% CI: 1.14-2.52) demonstrated greater knowledge than other ages regarding the telephone number of the emergency medical services. CONCLUSIONS: There was a knowledge deficit with regard to recognizing stroke and activating the emergency medical services. The findings apply to the sample investigated and suggest that there is a need for stroke educational interventions, starting in high school.

A study of clinical and etiological profile in elderly individuals presenting to a tertiary care center of South India with altered mental status

Background and Objectives: Altered mental status (AMS) is a challenging diagnosis in elderly patients and has a wide range of etiologies. The aim of this study was to know the clinical and etiological profile in the elderly, so that physicians will be better aware of AMS backgrounds and reducing morbidity and mortality rates among the patients. Materials and Methods: This was a prospective observational study conducted at the emergency department (ED) and medical intensive care unit (MICU) of a tertiary care hospital in South India from November 1, 2019, to October 31, 2020. Patients aged 65 years and older who presented to the ED and MICU with AMS were included in this study. They were evaluated clinically and necessary investigations were done to know the etiologies. Results: Among 100 elderly patients, 64% belonged to young old (age group of 65–74 years), 30% belonged to old (age group of 75–84 years), and 6% belonged to oldest old (>85 years). Sixty?one percent were male and 39% were female. The most common cause for AMS in elderly was primary neurological cause (40%, cerebrovascular accident was most common cause). The other causes were metabolic encephalopathy (29%, hyponatremia being most common) followed by multifactorial causes (24%). Infections and hypertensive encephalopathy were noted in 6% and 1% respectively. The common comorbidities found were hypertension (71%) and type 2 diabetes mellitus (50%), and 28% had diabetes mellitus and hypertension, whereas 25% had multiple comorbidities. Conclusion: The elderly patients who present with AMS must be screened for the above etiologies. This study helps the physicians to have an idea regarding common causes of AMS in elderly patients at presentation, hence appropriate management approach thus helps in reducing morbidity and mortality.

Efectos del Ejercicio Físico Aeróbico sobre los Factores de Riesgo Modificables que Predisponen a un Segundo Evento de Accidente Cerebrovascular. Revisión Sistemática / Effects of Aerobic Physical Exercise on Modifiable Risk Factors that Predispose to a Second Stroke Event. Systematic review

Introducción. El accidente cerebrovascular (ACV) es una condición de salud que ha aumentado su prevalencia en los últimos años, la cual se encuentra intrínsecamente asociada a la presencia de enfermedades crónicas no transmisibles (ECNT), como lo son la diabetes mellitus, dislipidemia e hipertensión, las que, de no ser controladas tras la instauración del primer episodio, predisponen a la afección de un segundo evento de ACV. Es sabido que el ejercicio físico aeróbico juega un rol fundamental en el control de las ECNT, junto con otros factores, como lo son los cambios de hábitos y adherencia a los tratamientos farmacológicos. Objetivo. Analizar los efectos que tiene el ejercicio físico aeróbico en población secuelada de un ACV sobre las ECNT que predisponen a sufrir un segundo evento cerebrovascular. Método. Se realizó una exhaustiva búsqueda en las bases de datos EBSCO, Scielo, PubMed y PEdro, utilizando las palabras claves "stroke and modifiable risk factors and aerobic physical exercise"; obteniendo un total de 56438 artículos. Para la selección, se consideraron los siguientes criterios de inclusión: pacientes entre 45 y 65 años con secuelas de ACV de más de 6 meses, que analizaran el efecto del ejercicio físico sobre las ECNT tras un evento cerebrovascular. Resultados. Se seleccionaron tres artículos científicos tipo ensayo clínico aleatorizados controlados, los cuales analizan los efectos que produce el ejercicio físico aeróbico sobre las ECNT tras un ACV. Entre los resultados con mayor significancia estadística (P entre 0.01 y 0.05) se encuentra el aumento en el consumo peak de oxígeno y el aumento en el colesterol HDL. Conclusiones. Es indispensable sistematizar la información de los programas de rehabilitación neurológica, que permitan levantar datos de las intervenciones, y así poder potenciar el ejercicio físico aeróbico de forma segura para poder controlar las ECNT subyacentes y así prevenir futuros eventos cerebrovasculares.

Background. Cerebrovascular accident (CVA) is a health condition that has suspected its prevalence in recent years, which is intrinsically associated with the presence of chronic non-communicable diseases (CNCD), such as diabetes mellitus, dyslipidemia and hypertension, which, if not controlled after the establishment of the first episode, predispose to the condition of a second stroke event. It is known that aerobic physical exercise plays a fundamental role in the control of NCDs, along with other factors, such as changes in habits and adherence to pharmacological treatments. Objective. To analyze the effects of aerobic physical exercise in the population after a stroke on NCDs that predispose to a second cerebrovascular event. Method. An exhaustive search was carried out in the EBSCO, Scielo, PubMed and PEdro databases, using the keywords "stroke and modifiable risk factors and aerobic physical exercise"; obtaining a total of 56438 articles. For selection, consider the following inclusion criteria: patients between 45 and 65 years of age, stroke sequelae of more than 6 months, who will analyze the effect of physical exercise on NCDs after a cerebrovascular event. Results. Three controlled randomized clinical trial were selected, which analyze the effects produced by aerobic physical exercise on NCDs after a stroke. Among the results with the highest statistical significance (P between 0.01 and 0.05) is the increase in peak oxygen consumption and the increase in HDL cholesterol. Conclusion. It is essential to systematize the information on neurological rehabilitation programs, to collect data from the interventions, and thus be able to promote aerobic physical exercise safely to control the underlying NCDs and thus prevent future cerebrovascular events.

Corneal confocal microscopy and its application in ischemic cerebrovascular disease / 国际脑血管病杂志

Corneal confocal microscopy (CCM) is an in vivo corneal imaging technique, which can directly quantify corneal nerve fibers in real time. It has the characteristics of non-invasive, objective and high sensitivity. CCM can not only be used for the diagnosis and treatment evaluation of corneal diseases, but also plays an important role in the diagnosis and prognosis evaluation of some peripheral and central nervous system diseases, such as diabetes peripheral neuropathy and Parkinson's disease. In addition, the changes of corneal nerve fibers can indirectly reflect the severity of ischemic cerebrovascular disease, and it is expected to become a noninvasive bioimaging marker of ischemic cerebrovascular disease. This article reviews CCM and its application in ischemic cerebrovascular disease, in order to provide better means for early diagnosis and prognosis evaluation of ischemic cerebrovascular disease.

Specific health-related quality of life in Cerebrovascular accident survivors: associated factors / Calidad de vida relacionada a la salud específica de supervivientes de accidente cerebrovascular: factores relacionados / Qualidade de vida relacionada à saúde específica de sobreviventes de acidente vascular encefálico: fatores associados

ABSTRACT Objectives: to identify factors associated with specific health-related quality of life in cerebrovascular accident, or stroke, survivors. Methods: cross-sectional study, carried out with 160 cerebrovascular accident survivors. Data were collected using the Barthel Index, Cerebrovascular Accident Specific Quality of Life Scale, and semi-structured instruments for sociodemographic and clinical data, analyzed by descriptive and inferential statistics. Results: health-related quality of life was associated with work activity (p=0.027), physical activity (p=0.007), functional capacity (p=0.001), presence of caregiver (<0.001), motor alteration (p = 0.001) and rehabilitation (p=0.003). The functionally dependent people were 14.61 times more likely to present low health-related quality of life, and those with motor impairment were 3.07 times more likely. Conclusions: it was evidenced that functional dependence and motor impairment increase the chance of low health-related quality of life in cerebrovascular accident survivors.

Prevalence of cerebrovascular accident and its associated risk factors among patients admitted into the neurological ward of university of Benin teaching hospital

Stroke is the second leading cause of death, accounting for 11.13 % of total deaths, and the main cause of disability worldwide. Objective: To determine the prevalence of stroke, its associated risk factors and survival rate among patients admitted to the neurological ward of University of Benin Teaching Hospital, Benin City, Edo State. Methods: A retrospective descriptive survey of patients admitted to the neurological ward of University of Benin Teaching Hospital, Benin City, Edo State from 2015 to 2020. A proforma was used to collect relevant data from medical records. Data was analyzed with IBM SPSS Statistics version 23, using descriptive and inferential statistics at 5% level of significance. Result: The average prevalence of cerebrovascular accident over the six years under review was 58.9%. Highest (69.3%) prevalence was recorded in 2018. Males (52.9%) were more affected than females and the age range 70-89 years was most affected (47.6%). The commonest comorbidities were hypertension and diabetes mellitus. Survival rate was high during the period under review, it was at the least in 2016 at 67.1% and highest in 2019 at 76%. Multiple logistic regression shows that patients who had CVA at below 30 years old were less likely to survive (OR;0.06: CI: 0.000-0.114; p = 0.001). Being married conferred a greater likelihood of surviving a CVA (OR;5.34: CI: 1.135 -25.135; p = 0.034) than being unmarried (OR;2.89: CI: 2.702-49.673; p = 0.004). Tertiary level of education conferred the greatest likelihood of surviving a CVA (OR;8.00: CI: 24.401-1168.674; p = 0.000). Conclusion: The prevalence of stroke from this study was high. Hypertension and diabetes mellitus were the most common risk factors associated with stroke. In-hospital stroke survival rate was high. The findings from this study can support advocacy for more efficient community-based programs geared towards awareness creation about stroke, its risk factors and prevention.

Factores de riesgo para enfermedad cerebrovascular en el adulto mayor / Risk Factors for Cerebrovascular Disease in the Older Adult

Introducción: La vejez está subvalorada, poco se piensa en el bienestar físico y psicosocial del anciano. La enfermedad cerebrovascular tiene como factores de riesgo comorbilidades como la hipertensión arterial, la diabetes mellitus, la dislipidemia, cardiopatías o malos estilos de vida como el consumo de cigarrillo, la obesidad y la poca actividad física, todos estos comunes en esta etapa de la vida. Objetivo: Identificar los factores de riesgo que presentan los adultos mayores para sufrir enfermedad cerebrovascular de un centro gerontológico de la ciudad de Medellín. Métodos: Fue una investigación descriptiva, de tipo transversal; se indagaron 37 adultos mayores con historias clínicas y exámenes de laboratorio. Se midieron los niveles de hemoglobina glicosilada, colesterol total, colesterol de baja densidad, colesterol de alta densidad y triglicéridos. Resultados: Se evidenció que la población era en su mayoría de sexo masculino con 51,4 por ciento y el sexo femenino con 48,6 por ciento; con rango de edad entre 60 y 70 años el 51,4 por ciento. Los factores de riesgo más relevantes fueron el índice de masa corporal mayor o igual a 25 con (75,7 por ciento), hipertensión arterial y no realizar actividad física. Conclusiones: Se logró determinar los principales factores de riesgo que tienen estos adultos mayores para sufrir enfermedad cerebrovascular; con resultados algunos similares y otros diferentes a estudios a nivel mundial. Con actividades de promoción y prevención se pueden intervenir estilos de vida de la población(AU)

Introduction: Old age is undervalued; little is thought about the physical and psychosocial well-being of the elderly. Among the risk factors of cerebrovascular disease, there are comorbidities, such as high blood pressure, diabetes mellitus, dyslipidemia and cardiopathies, or poor lifestyles like cigarette smoking, obesity and little physical activity, all of which are common at this stage of life. Objective: To identify, in a gerontological center in Medellín City, the risk factors that older adults present for being affected by cerebrovascular disease. Methods: This was a descriptive and cross-sectional research carried out with 37 older adults with medical antecedents and laboratory tests. The levels of glycated hemoglobin, total cholesterol, low-density and high-density cholesterol, as well as triglycerides were measured. Results: It was evidenced that the population was mostly male (51.4 por ciento), while females accounted for 48.6 por ciento. Their age range was mostly between 60 and 70 years (51.4 por ciento). The most relevant risk factors were body mass index greater than or equal to 25 (75.7 por ciento), arterial hypertension and not doing any physical activity. Conclusions: It was possible to determine the main risk factors for these older adults being affected by cerebrovascular disease; in this respect, some results were similar to and others were different from studies worldwide.

Introducción: El accidente cerebrovascular es una de las causas más comunes de mortalidad a nivel mundial. Objetivo: Determinar la asociación existente entre el desarrollo de afecciones neurológicas y la necesidad de ventilación mecánica con el aumento de la incidencia de mortalidad en la unidad de cuidados intensivos. Métodos: Estudio observacional, prospectivo de corte transversal, realizado en la unidad de cuidados intensivos de un hospital de atención secundaria. La población de estudio estuvo constituida por 52 pacientes con accidente cerebrovascular los cuales recibieron soporte respiratorio artificial entre los años 2018 y 2020. La variable de interés final fue la mortalidad. Los factores neurológicos estudiados fueron el tipo de accidente cerebrovascular, puntuación de la escala de coma de Glasgow, ausencia de reflejos de tallo encefálico, anisocoria y complicaciones neurológicas. El nivel de significación se halló según p valor ≤ 0,05 a través de Chi cuadrado de independencia. Resultados: La mortalidad proporcional predominó en el accidente cerebrovascular hemorrágico tipo hemorragia intracraneal no traumática (p= 0,118), ausencia de reflejos del tallo encefálico (p=0,000), anisocoria (p=0,000), escala de coma de Glasgow <8 puntos (p=0,000) y complicaciones neurológicas como la hipertensión endocraneana (p=0,010). Conclusiones: Los factores neurológicos asociados a la mortalidad fueron la ausencia de reflejos del tallo encefálico, anisocoria, escala de coma de Glasgow <8 puntos y complicaciones neurológicas como la hipertensión endocraneana(AU)

Introduction: Cerebrovascular accident is one of the commonest causes of mortality in the world. Objective: To determine the association between development of neurological disorders and the need for mechanical ventilation with an increased incidence of mortality in the intensive care unit. Methods: An observational, prospective and cross-sectional study was carried out in the intensive care unit of a secondary care hospital. The study population consisted of 52 patients with cerebrovascular accident who received artificial respiratory support between 2018 and 2020. The final variable of interest was mortality. The neurological factors studied were type of cerebrovascular accident, score according to the Glasgow coma scale, absence of brainstem reflexes, anisocoria, and neurological complications. The level of significance was determined according to P ≤ 0.05, through chi-square of independence. Results: Proportional mortality prevailed in hemorrhagic cerebrovascular accident of nontraumatic intracranial hemorrhage type (P=0.118), absence of brainstem reflexes (P=0.000), anisocoria (P=0.000), score of less than eight points according to the Glasgow coma scale (P=0.000), and neurological complications such as endocranial hypertension (P=0.010). Conclusions: The neurological factors associated with mortality were absence of brainstem reflexes, anisocoria, score of less than eight points according to the Glasgow coma scale, and neurological complications such as endocranial hypertension(AU)

Accidente cerebrovascular isquémico en un adulto joven

RESUMEN Presentamos caso de un varón de 39 años con antecedentes de varios accidentes isquémicos transitorios que siempre resolvieron rápida y espontáneamente. Fue sometido a varios estudios cardiovasculares, neurovasculares y de neuro y angioimagen que resultaron normales. El paciente se presentó a consulta con una paresia facio-braquial derecha y disartria. Sin embargo, el cuadro cedió en el transcurso de horas a pesar de manifestarse una isquemia en los estudios neurovasculares. Por todo lo anterior se decidió estudiar trombofilias presentándose el resultado de una mutación del gen G20210A de la protrombina. Al alta, en tratamiento con anticoagulantes orales, el paciente se presenta asintomático con monitoreo mensual continuo.

ABSTRACT We present the case of a 39-year-old man with a history of several transient ischemic attacks that always resolved quickly and spontaneously. He underwent several cardiovascular, neurovascular, and neuro and angioimaging studies that were normal. The patient presented for consultation with a right faciobrachial paresis and dysarthria. However, the condition subsided within hours despite ischemia manifested in neurovascular studies. For all the above, it was decided to study thrombophilias, finding the prothrombin G20210A mutation. Upon discharge, on treatment with oral anticoagulants, the patient is asymptomatic with continuous monthly monitoring.

Stroke in COVID-19 and Pregnancy: A Case Report

Abstract Neurological manifestations add prognostic severity to the coronavirus disease (COVID-19). Here, we report a case of a pregnant patient with COVID-19 that progressed with neurological complications. Magnetic resonance imaging revealed cerebral ischemic insults associated with cortical laminar necrosis, in addition to an intraparenchymal brain hematoma. The mechanisms of vascular injury may have multifactorial origins and result in complex radiological presentations. Since stroke associated with pregnancy is one of the main causes of long-term disability in women, accurate identification of cerebrovascular events may potentially reduce sequelae.

Prognostic power of conventional echocardiography in individuals without history of cardiovascular diseases: A systematic review and meta-analysis

Echocardiographic abnormalities are associated with a higher incidence of adverse cardiovascular outcomes. This systematic review and meta-analysis aimed to evaluate whether echocardiographic abnormalities are predictors of cardiovascular events in individuals without previous cardiovascular diseases. The PubMed, Scopus, and SciELO databases were searched for longitudinal studies investigating the association between echocardiographic abnormalities and cardiovascular events among individuals without known cardiovascular diseases. Two independent reviewers analyzed data on the number of participants, age and sex, echocardiographic alterations, follow-up time, and cardiovascular outcomes. The meta-analysis estimated the risk ratio (RR) and 95% confidence interval (CI). Heterogeneity was assessed using I2 test. Twenty-two longitudinal studies met the eligibility criteria, comprising a total of 55,603 patients. Left ventricular hypertrophy (LVH) was associated with non-fatal cardiovascular events (RR 2.16; 95% CI 1.22-3.84), death from cardiovascular disease (RR 2.58; 95% CI 1.83- 3.64), and all-cause mortality (RR 2.02; 95% CI 1.34-3.04). Left ventricular diastolic dysfunction (LVDD) and left atrial dilation (LA) were associated with fatal and non-fatal cardiovascular events (RR 2.01; 95% CI 1.32-3.07) and (RR 1.78; 95% CI 1.16-2.73), respectively. Aortic root dilation was associated with non-fatal cardiovascular events (RR 1.25; 95% CI 1.09-1.43). In conclusion, LVH, LVDD, dilations of the LA, and of the aortic root were associated with an increased risk of adverse events in individuals without previous cardiovascular diseases. This study suggests that simple data obtained on conventional echocardiography can be an important predictor of cardiovascular outcomes in a low-risk population.

Blood glucose variability, NIHSS score, APACHE II score, and prognosis in patients with acute and severe cerebrovascular disease / 中国基层医药

Objective:To investigate blood glucose variability, National Institutes of Health Stroke Scale (NIHSS) score, Acute Physiology and Chronic Health Evaluation II (APACHE II) score and prognosis in patients with acute and severe cerebrovascular disease, providing a reference for clinical treatment of this disease.Methods:The clinical data of 76 patients with acute and severe cerebrovascular disease who received treatment in Xixi Hospital of Hangzhou between January 2014 and December 2019 were retrospectively analyzed. These patients were divided into a survival group ( n = 51) and a death group ( n = 25) according to the prognosis 28 days after admission. Baseline data, baseline NIHSS score, APACHE II score, standard deviation of blood glucose, mean blood glucose, mean amplitude of glycemic excursions, and blood glucose variability rate were compared between the survival and death groups. The effects of these parameters on the prognosis of acute and severe cerebrovascular disease were analyzed. Results:There were no significant differences in gender, age, history of diabetes, type of disease, and length of hospital stay between the two groups ( χ2 = 1.674, t = 1.048, χ2 = 3.833, 0.263, t = 0.832, all P > 0.05). The proportion of patients with a history of hypertension in the death group was significantly higher than that in the survival group [15.69% (8/51) vs. 52.00% (13/25), χ2 = 11.063, P < 0.05]. There was no significant difference in mean blood glucose between the two groups ( t = 0.118, P > 0.05). The baseline NIHSS score, APACHE II score, standard deviation of blood glucose, mean amplitude of glycemic excursions and blood glucose variability rate in the death group were (24.41 ± 4.14) points, (25.00 ± 6.97) points, (2.72 ± 0.91) mmol/L, (6.27 ± 2.01) mmol/L, (34.83 ± 5.61) %,which were significantly higher than those in the survival group [(17.22 ± 3.63) points, (19.21 ± 5.36) points, (1.69 ± 0.70) mmol/L, (3.72 ± 1.68) mmol/L, (19.54 ± 3.22) %, t = 7.744, 3.999, 5.448, 5.823, 15.095, all P < 0.05]. The proportion of patients with blood glucose variability rate < 20% in the death group was significantly lower than that in the survival group [16.00% (4/25) vs. 74.51% (38/51), χ2= 23.230, P < 0.05]. The proportion of patients with blood glucose variability rate > 30% in the death group was significantly higher than that in the survival group [60.00% (15/25) vs. 13.73% (7/51), χ2 = 17.466, P < 0.05). Logistic regression analysis revealed that baseline NIHSS score, APACHE II score, standard deviation of blood glucose, mean amplitude of glycemic excursions, and blood glucose variability rate were the independent risk factors of death of cerebrovascular disease patients (all P < 0.05). Conclusion:In patients with acute and severe cerebrovascular disease, an obvious blood glucose fluctuation, high baseline NIHSS score, and high APACHE II score help to assess the prognosis of acute and severe cerebrovascular disease and determine the risk of death.

Infarto renal y disección carotídea espontánea: complicaciones de la displasia fibromuscular / Spontaneous renal infarction and carotid dissection: complications of fibromuscular dysplasia

Resumen La displasia fibromuscular es una enfermedad no inflamatoria y no aterosclerótica, que puede afectar cualquier lecho arterial; sin embargo, las arterias renales y la carótida interna son las más comprometidas. Se presenta el caso de un paciente que cursó con dolor abdominal y cefalea hemicraneana posterior, con síndrome de Horner incompleto. En arteriografía renal y panangiografía cerebral realizada por Cardiología intervencionista se observó infarto renal derecho y disección de la carótida interna derecha con formación de pseudoaneurisma. Se hizo terapia endovascular con angioplastia y se dio de alta con antiagregación dual. Es importante conocer este tipo de presentación clínica ya que el diagnóstico podría confundirse con otras enfermedades que generan signos y síntomas similares; por consiguiente, es ideal tener sospecha clínica alta para evitar retrasos en el manejo.

Abstract Fibromuscular dysplasia is a non-inflammatory and non-atherosclerotic disease that can affect any arterial bed, with the renal and the internal carotid arteries being the most compromised. A case is presented on a patient that had abdominal pain and pain in the back of the head, and an incomplete Horner syndrome. In the renal arteriography and cerebral pan-angiography carried out by interventionist Cardiology, a right renal infarction and dissection of the right internal carotid was observed with a pseudo-aneurysm formation. Intravenous treatment was performed with angioplasty, and the patient was discharged with dual antiplatelet therapy. It is important to be aware of this type of clinical presentation, since the diagnosis can be confused with other diseases that produce similar signs and symptoms. It would be ideal to have a high clinical suspicion in order to avoid delays in the management.
