Prevalence and Factors Associated with Carotid Stenosis in Acute Ischemic Stroke Patients with Atrial Fibrillation.

INTRODUCTION: Among stroke patients with atrial fibrillation (AF), it is not uncommon to identify carotid atherosclerosis. This study aimed to estimate the prevalence of, and factors associated with, carotid atherosclerosis among patients with AF and acute ischemic stroke. PATIENTS AND METHODS: Prospectively collected data from consecutive patients with anterior ischemic stroke and AF who underwent carotid imaging from 10 stroke registries were categorized retrospectively according to the degree of stenosis in: no atherosclerosis, stenosis <50%, stenosis ≥50%, and occlusion. Logistic regression analysis was used to identify factors associated with ipsilateral carotid atherosclerosis. RESULTS: Among 2,955 patients with ischemic stroke and AF, carotid atherosclerosis was evident in 1,022 (34.6%) patients, while carotid stenosis ≥50% and occlusion were identified in 204 (6.9%) and 168 (5.7%) patients, respectively. Ipsilateral carotid stenosis ≥50% or occlusion was associated with higher age (OR: 1.15, 95% CI: 1.01-1.32, per decade), previous ischemic stroke or transient ischemic attack (OR: 1.70, 95% CI: 1.29-2.25), peripheral artery disease (OR: 1.85, 95% CI: 1.23-2.78), coronary artery disease (OR: 1.53, 95% CI: 1.16-2.04), and statin treatment on admission (OR: 1.30, 95% CI: 1.01-1.67). Patients with lacunar stroke had a lower likelihood of stenosis ≥50% or occlusion (OR: 0.29, 95% CI: 0.13-0.68). Compared to the absence of atherosclerotic disease, atherosclerosis in one and two arterial beds was associated with the identification of ipsilateral carotid stenosis (OR: 1.49, 95% CI: 1.22-2.98 and OR: 3.18, 95% CI: 1.85-5.49, respectively). CONCLUSION: Among acute ischemic stroke patients with AF, 1 out of 3 had ipsilateral carotid atherosclerosis, and 1 out of 8 had ipsilateral carotid stenosis ≥50% or occlusion. Atherosclerosis in two arterial beds was the most important predictor for the identification of ipsilateral carotid stenosis. Among ischemic stroke patients with AF, carotid atherosclerosis is common, while carotid imaging should not be overlooked, especially in those with coronary or/and peripheral artery disease.

Availability and barriers to access post-stroke rehabilitation in Latin America.

OBJECTIVES: To describe the availability and barriers to access post-stroke rehabilitation services in Latin America. MATERIALS AND METHODS: We conducted a multi-national survey in Latin American countries. The survey consisted of three sections: (1) the national state of post-stroke rehabilitation; (2) the local state of post-stroke rehabilitation; and (3) the coverage and financing of post-stroke services. Stroke leaders from the surveyed countries were involved in developing and disseminating the survey. RESULTS: 261 responses were collected from 17 countries. The mean age of respondents was 42.4 ± 10.1 years, and 139 (54.5 %) of the respondents were male. National clinical guidelines for post-stroke rehabilitation were reported by 67 (25.7 %) of the respondents. However, there were discrepancies between respondents within the same country. Stroke units, physiotherapy, occupational therapy, speech therapy, and neuropsychological therapy services were less common in public than private settings. The main barriers for inpatient and outpatient services included limited rehabilitation facilities, coverage, and rehabilitation personnel. The main source of financing for the inpatient and outpatient services was the national health insurance, followed by out-of-pocket payments. Private and out-of-pocket costs were more frequently reported in outpatient services. CONCLUSIONS: Post-stroke rehabilitation services in Latin American countries are restricted due to a lack of coverage by the public health system and private insurers, human resources, and financial aid. Public settings offer fewer post-stroke rehabilitation services compared to private settings. Developing consensus guidelines, increasing coverage, and using innovative approaches to deliver post-stroke rehabilitation is paramount to increase access without posing a financial burden.

Incidence and case-fatality rate of stroke in General Villegas, Buenos Aires, Argentina. The EstEPA population study.

OBJECTIVES: Stroke epidemiology varies among different populations. The burden of stroke is high in low- and middle-income countries. Reliable population data is needed to assess the impact of stroke and to develop policies aimed to improve stroke care in our region. EstEPA is a population-based project assessing prevalence, incidence, mortality and burden of stroke in General Villegas Department, Buenos Aires, Argentina (pop=30,864 inhabitants). We determined incidence of stroke (first-ever and recurrent stroke) and stroke case-fatality rate from 2017 to 2020. METHODS: First-ever strokes, recurrent strokes and transient ischemic attacks were ascertained and case-fatality rate was obtained. Diagnoses were based on standard AHA/WHO definitions. Study population included all persons residing in General Villegas during the three-year period. Hospitals, households, nursing homes, death certificates and several overlapping sources were surveyed. RESULTS: We assessed 92,592 person-years. There were 155 cerebrovascular events aged 70 years (SD ± 13 years), of which 115 were first-ever strokes (74%), 21 recurrent strokes (13.5%) and 19 transient ischemic attacks (12.5%). The crude overall incidence rate of first-ever strokes was 124.2 per 100,000 population (86.9 per 100,000 [95% CI 58.5-115.2] when standardized by WHO World population and 109.7 per 100,000 [95% CI 89.7-129.8] when standardized by Argentine population) and 317.0 per 100,000 population in subjects older than 40 years. Case fatality rate at 30 days of first-ever strokes was 27%. CONCLUSION: In this population-based comprehensive stroke epidemiological study in Argentina, first-ever stroke incidence in an urban population was 124.2 per 100,000 population (86.9 per 100,000 adjusted by the WHO World population). This is lower than the incidence in other countries in the region and similar to a recent incidence study in Argentina. It is also comparable to reported incidence in most middle- and high-income countries. Stroke case-fatality rate was comparable to other population-based Latin-American studies.

Argentinian clinical genomics in a leukodystrophies and genetic leukoencephalopathies cohort: Diagnostic yield in our first 9 years.

INTRODUCTION AND OBJECTIVES: Leukodystrophies and genetic leukoencephalopathies constitute a vast group of pathologies of the cerebral white matter. The large number of etiopathogenic genes and the frequent unspecificity on the clinical-radiological presentation generate remarkable difficulties in the diagnosis approach. Despite recent and significant developments, molecular diagnostic yield is still less than 50%. Our objective was to develop and explore the usefulness of a new diagnostic procedure using standardized molecular diagnostic tools, and next-generation sequencing techniques. MATERIALS AND METHODS: A prospective, observational, analytical study was conducted in a cohort of 46 patients, evaluated between May 2008 and December 2016, with a suspected genetic leukoencephalopathy or leukodystrophy. A diagnostic procedure was set up using classical monogenic tools in patients with characteristic phenotypes, and next-generation techniques in nonspecific ones. RESULTS: Global diagnostic procedure yield was 57.9%, identifying the etiological pathogenesis in 22 of the 38 studied subjects. Analysis by subgroups, Sanger method, and next-generation sequencing showed a yield of 64%, and 46.1% respectively. The most common pathologies were adrenoleukodystrophy, cerebral autosomal-dominant arteriopathy with subcortical infarcts (CADASIL), and vanishing white matter disease. CONCLUSIONS: Our results confirm the usefulness of the proposed diagnostic procedure expressed in a high diagnostic yield and suggest a more optimal cost-effectiveness in an etiological analysis phase.

Control of Vascular Risk Factors and Response to Stroke Symptoms in Argentina During the COVID-19 Quarantine. The SIFHON-COVID Population Survey.

Background and Objectives: In preparation for the suspected influx of COVID-19 patients, many healthcare systems reduced or discontinued provision of "non-urgent" care. This decision had potential impact on stroke prevention and management. We conducted a large population survey to assess the effect of mandatory social isolation on routine health controls, emergency consultations and other stroke care-related behaviors of the population during the pandemic. Methods: We distributed multiple-choice anonymous questionnaires through the institutional email database and through the email database of clients of a beverage delivery company. Most respondents resided in the metropolitan area of Buenos Aires. This is the area where the infection rates were highest and restriction measures were hardest. The survey assessed demographic characteristics and actual and potential behaviors of people regarding medical checkups, risk factors control, medication provision and response to onset of symptoms consistent with stroke or TIA. Surveys were sent during May 2020, the strictest period of the quarantine in Argentina. Results: A total of 10,303 questionnaires were completed. Thirty-seven percent of the respondents were older than 60 years, 74% were women and 16% lived alone. Vascular risk factors were present in 39% of the individuals. Seventy-six percent did not continue with their regular medical checkups during the mandatory social and preventive isolation, 21% had difficulty obtaining medical prescriptions and only 38% considered that health institutions had implemented reliable safety measures to avoid exposure to COVID-19. When asked about response in case of onset of stroke symptoms, 9% would not consult given the context of the pandemic. Six percent reported having had symptoms consistent with stroke or TIA but only 35% went to a hospital. The vast majority of the respondents said they were awaiting for the end of the quarantine to resume their usual medical care. Conclusions: The implementation of a quarantine may have some serious adverse effects on the prevention, diagnosis and treatment of stroke. These undesirable aspects should be taken into consideration in the planning, communication and implementation of health policies.

[Use and results of intravenous fibrinolysis in a stroke unit]. / Uso y resultados de la fibrinolisis intravenosa en una unidad cerebrovascular.

Intravenous fibrinolysis with recombinant tissue plasminogen activator (rTPA) and use of stroke units improve morbidity and mortality in patients with acute ischemic stroke (AIS). However, data published in Argentina are scarce. We describe the experience in the use of fibrinolysis in patients with acute ischemic stroke (AIS) before and after the implementation of a stroke unit in a Comprehensive Stroke Center in Buenos Aires during the last 17 years. Retrospective analysis of consecutive patients treated with rTPA between January 2003 and December 2019. Treatment times, hospitalization time, post-treatment complications and disability at 3 months were evaluated. For the analysis, the pre and post opening periods of the stroke unit were evaluated, Period 1 (P1, from 2003 to 2011) and Period 2 (P2, from 2012 to 2019). Intravenous fibrinolysis was performed in 182 patients. Opening of the stroke unit resulted in an increase in the percentage of fibrinolysis over the total number of admitted strokes (4% in P1 vs. 10% in P2, p < 0.001), shortening of the door-to-needle time (75 minutes in P1 vs. 53 minutes in P2, p < 0.00001) and higher proportion of patients treated within 60 minutes of hospital admission (36% in P1 vs. 76% in P2, p < 0.00001). In addition, there was a reduction in the median hospital stay from 9 days in P1 to 5 days in P2 (p < 0.00001). In conclusion, stroke units seem to optimize the use of fibrinolysis in acute stroke, increasing the percentage of patients treated, reducing door-to-needle time, and reducing hospitalization time.

La fibrinólisis intravenosa con activador del plasminógeno tisular recombinante (rTPA) y la utilización de unidades cerradas, demostraron disminuir sustancialmente la morbimortalidad en pacientes con accidente cerebrovascular isquémico (ACVi). Sin embargo, los datos publicados en Argentina son escasos. Describimos la experiencia en la utilización de fibrinólisis en pacientes con ACVi agudo antes y después de la implementación de una unidad cerebrovascular (UCV) en un Centro Integral de Neurología Vascular de la Ciudad de Buenos Aires durante 17 años. Se realizó un análisis retrospectivo de pacientes consecutivos tratados con rTPA entre enero 2003 y diciembre 2019. Se evaluaron tiempos de tratamiento, de internación, complicaciones post tratamiento y discapacidad a 3 meses. Para su análisis se evaluaron los períodos pre y post apertura de la UCV, período 1 (P1 de 2003-2011) y P2 (2012 -2019). Se realizó fibrinolisis intravenosa en 182 pacientes. La apertura de UCV resultó en aumento del porcentaje de fibrinólisis sobre el total de los ACVi ingresados (4% en P1 vs. 10% en P2, p < 0.001), acortamiento del tiempo puerta-aguja (75 minutos en P1 vs. 53 minutos en P2, p < 0.00001) y mayor proporción de pacientes tratados dentro de los 60 minutos del ingreso hospitalario (36% en P1 vs. 76% en P2, p < 0.00001). Además, hubo reducción de la me diana de internación de 9 días en P1 a 5 días en P2 (p < 0.00001). En conclusión, la UCV parece optimizar la utilización de fibrinólisis en el ACVi agudo, aumentando el porcentaje de pacientes tratados, reduciendo el tiempo puerta-aguja y disminuyendo el de internación.

[Effect of the COVID-19 pandemic and preventive social isolation measures on the number of outpatient visits, hospitalizations and treatment of cerebrovascular accident in a neurological center in Argentina]. / Efecto de la pandemia COVID-19 y la cuarentena en el número de consultas, subtipos y tratamiento del accidente cerebrovascular en un centro neurológico de Argentina.

The COVID-19 pandemic and preventive and compulsory social isolation (PCSI) have generated changes in the organization and use of the health system around the world. We analyze the impact of the health situation on the number of outpatient visits, hospitalizations and access to revascularization therapy for cerebrovascular disease. The period from March 1 to July 31, 2020 was analyzed. It was compared with the same period in 2019. Total outpatient and hospital visits were evaluated, NIHSS scale (National Institute of Health Stroke Scale) upon admission, type of cerebrovascular disease and use of revascularization therapies; 197 patients with acute cerebrovascular events were admitted in 2019 and 150 patients in 2020. There was a significant decrease in the number of hospitalizations for total ischemic events and transient ischemic attacks in the comparison of 5 months. An increase in cerebral venous thrombosis and cerebral hemorrhages was also seen. Access to intravenous fibrinolysis and mechanical thrombectomy remained stable, but with prolonged door-to-needle time. Outpatient visits fell 67%, the decrease being greater in April and more marked in follow-up visits. The number of hospitalizations and outpatient visits during the PCSI dropped substantially. This seems to be due to strict compliance with quarantine and not to pathophysiological mechanisms related to COVID-19. The population should be educated about the need to control chronic diseases and acute events and safety measures should be guaranteed in health centers.

La pandemia por COVID-19 y el aislamiento social preventivo y obligatorio (ASPO) han generado cambios en la organización y utilización del sistema de salud en todo el mundo. Analizamos el impacto de la situación sanitaria en el número de consultas ambulatorias, internaciones y acceso a terapias de revascularización por enfermedad cerebrovascular. Se analizó el período desde el 1 marzo al 31 de julio de 2020. Se comparó con el mismo período de 2019. Se evaluaron total de consultas ambulatorias e internaciones, escala NIHSS (National Institute of Health Stroke Scale) al ingreso, tipo de enfermedad cerebrovascular y uso de terapias de revascularización. Ingresaron 197 pacientes con eventos cerebrovasculares agudos en 2019 y 150 pacientes en 2020. Hubo un descenso significativo en el número de internaciones por eventos isquémicos totales y accidentes isquémico transitorios en el comparativo de los 5 meses. Se vio además un aumento en trombosis venosas cerebrales y hemorragias cerebrales. El acceso a fibrinolisis intravenosa y trombectomía mecánica se mantuvo estable, pero con prolongación del tiempo puerta-aguja. Las consultas ambulatorias descendieron 67%, siendo mayor el descenso en abril y más marcado en consultas de seguimiento. El número de internaciones y de consultas ambulatorias durante el ASPO descendió sustancialmente. Esto pareciera obedecer al cumplimiento estricto de la cuarentena y no a mecanismos fisiopatológicos rel acionados con el COVID-19. Debe educarse a la población sobre la necesidad del control de enfermedades crónicas y de eventos agudos y se deben garantizar medidas de seguridad en los centros de salud.

Everything you always wanted to know about sex and Neurology: neurological disability and sexuality.

OBJECTIVE: Chronic neurological disorders generate disabilities affecting multiple aspects of life, including sexuality. OBJECTIVE: To describe the presence of sexual dysfunction and comorbidities in a population with chronic neurological disorders. To analyze the relationship between disability and sexual dysfunction. METHODS: A cross-sectional case-control study was carried out. Patients with amyotrophic lateral sclerosis (ALS), multiple sclerosis (MS), Parkinson's disease (PD), and stroke of at least one year since the onset of symptoms were included, and compared with controls with no neurological disease, matched by age and sex. RESULTS: We included 71 participants: 29 controls, with a mean age of 49.4 years, and 42 patients with a mean age of 53.8 years. Sexual dysfunction was present in 22.5% of the controls and 77.5% of the patients. A statistically significant relationship between sexual dysfunction and disability was found in the logistic regression analysis (OR = 20.38, 95%CI: 2.5 -165.86). CONCLUSIONS: Disability proved to be the main variable related to the presence of sexual dysfunction. Patients with ALS had the worst rates of sexual dysfunction. Patients with MS were similar to the control group. As for the PD group, no patient had normal sexuality. Finally, in stroke patients, the presence of comorbidities and their treatment may have negatively influenced sexuality. These findings showed that patients with chronic neurological diseases have sexual dysfunction and underscore the need for neurologists to know and address this problem.

Molecular Diagnosis in an Argentinean Mitochondrial Disorders Cohort

Abstract Mitochondrial diseases are multisystemic disorders characterized by an impairment of the mitochondrial respiratory chain. Diagnosis requires an approach that involves a high index of suspicion, molecular techniques and a careful selection of the tissue to be studied. Our goal was to develop and implement local strategies for diagnosing mitochondrial disorders, by standardizing procedures of molecular biology and nucleic acid sequencing. A prospective, analytical, observational study was conducted in a cohort of, a total of 82 patients with suspected mitochondrial disorder who were treated at our hospital between May 2008 and June 2019. We developed molecular diagnostic tools that included classical monogenic techniques and Next Generation Sequencing. We characterized the neurological and extra neurological manifestations noted in our cohort. Following the proposed algorithm, we obtained a molecular diagnostic performance of 54%, identifying mutations in 44 patients. mtDNA mutations were identified in 34 patients. Structural rearrangements in mitochondrial genome were found in 3 and 7 in nuclear genes, respectively. Our results confirm the utility of the proposed algorithm and the molecular tools used, as evidenced by a high diagnostic performance. This is of great value to a more efficient and comprehensive medical care of patients and families affected by mitochondrial disorders.

Consenso sobre accidente cerebrovascular isquémico agudo / Consensus on acute ischemic stroke

El accidente cerebrovascular es la tercera causa de muerte y la primera de discapacidad en la Argentina. Los eventos isquémicos constituyen el 80% de los casos. Los accidentes vasculares cerebrales requieren la implementación de protocolos sistematizados que permitan reducir los tiempos en la atención, la morbilidad y mortalidad. En el consenso participaron especialistas de nueve sociedades médicas relacionadas con la atención de pacientes con enfermedad cerebrovascular. Se consensuó un temario separado en capítulos y para la redacción de los mismos se conformaron grupos de trabajo con miembros de diferentes especialidades médicas. Se discutió y acordó para cada tema el nivel de recomendación en base a la mejor evidencia clínica disponible para cada tópico. Se realizó una adaptación al ámbito local de las recomendaciones cuando se consideró necesario. El sistema de la American Heart Association se utilizó para redactar las recomendaciones y su grado de evidencia. La corrección y edición fue realizada por cinco revisores externos, que no participaron en la redacción y con amplia experiencia en enfermedad vascular. Finalizado el documento preliminar, se organizó una reunión general con todos los integrantes de los grupos de trabajo y los revisores para redactar las recomendaciones definitivas. El consenso abarca la atención del paciente con accidente cerebrovascular isquémico en la fase pre-hospitalaria, evaluación inicial en la central de emergencias, terapias de recanalización (trombolisis y/o trombectomía mecánica), craniectomía descompresiva, neuroimágenes y cuidados clínicos en la internación.

Stroke is the third cause of death and the first cause of disability in Argentina. Ischemic events constitute 80% of cases. It requires the implementation of systematized protocols that allow reducing the time of care, morbidity and mortality. Specialists from nine medical societies related to the care of patients with cerebrovascular disease participated in the consensus. A separate agenda was agreed upon in chapters and for the writing of them, work groups were formed with members of different medical specialties. The level of recommendation was discussed and agreed upon for each topic based on the best clinical evidence available for each of them. An adaptation to the local scope of the recommendations was made when it was considered necessary.The American Heart Association system was used to draft the recommendations and their level of evidence. The correction and editing were done by five external reviewers, who did not participate in the writing and with extensive experience in vascular pathology. Once the preliminary document was finalized, a general meeting was held with all the members of the working groups and the reviewers to reach final recommendations. The consensus covers the management of ischemic stroke in the pre-hospital phase, initial evaluation in the emergency center, recanalization therapies (thrombolysis and/ or mechanical thrombectomy), decompressive craniectomy, neuroimaging and clinical care in the hospital.

RESUMO Las enfermedades neurológicas crónicas generan discapacidad afectando múltiples aspectos de la vida, incluida la sexual. Objetivo Describir en una población con enfermedades neurológicas crónicas la presencia de disfunción sexual y posibles comorbilidades acompañantes. Analizar la relación entre discapacidad y disfunción sexual. Métodos Se realizó un estudio transversal de tipo casos y controles. Se incluyeron pacientes con Esclerosis Lateral Amiotrófica (ELA), Esclerosis Múltiple (EM), enfermedad de Parkinson (EP) y secuelados por enfermedad cerebrovascular (sACV) de al menos un año de evolución, controlando con sujetos sin enfermedad neurológica pareados por edad y sexo. Resultados Se incluyeron 71 sujetos: 29 controles, con una edad media 49,4 años y 42 casos con una edad media de 53,8 años. Presentaron disfunción sexual el 22,5% de los controles y el 77,5% de los casos. En el análisis por regresión logística se encontró una relación estadísticamente significativamente entre disfunción sexual y discapacidad. (OR = 20.38, IC95%: 2.5-165.86). Conclusiones La discapacidad demostró ser la principal variable relacionada con la presencia de disfunción sexual. Los enfermos con ELA fueron los que peores índices de disfunción sexual presentaron. Los pacientes con EM se comportaron de forma similar al grupo control. En cuanto al grupo de EP todos los pacientes tuvieron algún trastorno en su sexualidad. Por último, en sACV la presencia de comorbilidades y su tratamiento podrían influir negativamente en la sexualidad. Estos hallazgos evidencian que la disfunción sexual está presente en los pacientes con enfermedades neurológicas crónicas y confirma la necesidad de conocer este problema por parte de los neurólogos.
