Impact of the COVID-19 pandemic on the organisation of stroke care. Madrid Stroke Care Plan

La sobrecarga asistencial y los cambios organizativos frente a la pandemia de COVID-19 podrían estar repercutiendo en la atención al ictus agudo en la Comunidad de Madrid. Métodos: Encuesta estructurada en bloques: características del hospital, cambios en infraestructura y recursos, circuitos de código ictus, pruebas diagnósticas, rehabilitación y atención ambulatoria. Análisis descriptivo según el nivel de complejidad en la atención del ictus (disponibilidad o no de unidad de ictus y de trombectomía mecánica). Resultados: De los 26 hospitales del SERMAS que atienden urgencias en adultos, 22 cumplimentaron la encuesta entre el 16 y 27 de abril. El 95% han cedido neurólogos para atender a pacientes afectados por la COVID-19. Se han reducido camas de neurología en el 89,4%, modificado los circuitos en urgencias para ictus en el 81%, con circuitos específicos para sospecha de infección por SARS-CoV2 en el 50%, y en el 42% de los hospitales los pacientes con ictus agudo positivos para SARS-CoV2 no ingresan en camas de neurología. Ha mejorado el acceso altratamiento, con trombectomía mecánica las 24 h en el propio hospital en 10 hospitales, y sehan reducido los traslados interhospitalarios secundarios. Se ha evitado el ingreso de pacientescon ataque isquémico transitorio o ictus leve (45%) y se han incorporado consultas telefónicaspara seguimiento en el 100%.Conclusiones: Los cambios organizativos de los hospitales de la Comunidad de Madrid frente ala pandemia por SARS-Co2 han modificado la dedicación de recursos humanos e infraestructurasde las unidades de neurología y los circuitos de atención del ictus, realización de pruebasdiagnósticas, ingreso de los pacientes y seguimientoThe overload of the healthcare system and the organisational changes made inresponse to the COVID-19 pandemic may be having an impact on acute stroke care in the Regionof Madrid.Methods: We conducted a survey with sections addressing hospital characteristics, changes ininfrastructure and resources, code stroke clinical pathways, diagnostic testing, rehabilitation,and outpatient care. We performed a descriptive analysis of results according to the level ofcomplexity of stroke care (availability of stroke units and mechanical thrombectomy).Results: The survey was completed by 22 of the 26 hospitals in the Madrid Regional HealthSystem that attend adult emergencies, between 16 and 27 April 2020. Ninety-five percent ofhospitals had reallocated neurologists to care for patients with COVID-19. The numbers of neuro-logy ward beds were reduced in 89.4% of hospitals; emergency department stroke care pathwayswere modified in 81%, with specific pathways for suspected SARS-CoV2 infection established in50% of hospitals; and SARS-CoV2-positive patients with acute stroke were not admitted to neu-rology wards in 42%. Twenty-four hour on-site availability of mechanical thrombectomy wasimproved in 10 hospitals, which resulted in a reduction in the number of secondary hospitaltransfers. The admission of patients with transient ischaemic attack or minor stroke was avoi-ded in 45% of hospitals, and follow-up through telephone consultations was implemented in100%.Conclusions: The organisational changes made in response to the SARS-Co2 pandemic in hos-pitals in the Region of Madrid have modified the allocation of neurology department staff andinfrastructure, stroke units and stroke care pathways, diagnostic testing, hospital admissions,and outpatient follow-u

Identification of the Immunological Changes Appearing in the CSF During the Early Immunosenescence Process Occurring in Multiple Sclerosis

Patients with multiple sclerosis (MS) suffer with age an early immunosenescence process, which influence the treatment response and increase the risk of infections. We explored whether lipid-specific oligoclonal IgM bands (LS-OCMB) associated with highly inflammatory MS modify the immunological profile induced by age in MS. This cross-sectional study included 263 MS patients who were classified according to the presence (M+, n=72) and absence (M-, n=191) of LS-OCMB. CSF cellular subsets and molecules implicated in immunosenescence were explored. In M- patients, aging induced remarkable decreases in absolute CSF counts of CD4+ and CD8+ T lymphocytes, including Th1 and Th17 cells, and of B cells, including those secreting TNF-alpha. It also increased serum anti-CMV IgG antibody titers (indicative of immunosenescence) and CSF CHI3L1 levels (related to astrocyte activation). In contrast, M+ patients showed an age-associated increase of TIM-3 (a biomarker of T cell exhaustion) and increased values of CHI3L1, independently of age. Finally, in both groups, age induced an increase in CSF levels of PD-L1 (an inductor of T cell tolerance) and activin A (part of the senescence-associated secretome and related to inflammaging). These changes were independent of the disease duration. Finally, this resulted in augmented disability. In summary, all MS patients experience with age a modest induction of T-cell tolerance and an activation of the innate immunity, resulting in increased disability. Additionally, M- patients show clear decreases in CSF lymphocyte numbers, which could increase the risk of infections. Thus, age and immunological status are important for tailoring effective therapies in MS.This work was supported by grants FIS-PI15/00513, FIS-PI18/00572 and RD16/0015/0001 from the Instituto de Salud Carlos III.

Acute stroke care during the COVID-19 pandemic. Ictus Madrid Program recommendations

La pandemia por COVID-19 ha obligado a una reorganización de los sistemas sanitarios y ha comportado una saturación excepcional de sus recursos. En este contexto es vital asegurar la atención al ictus agudo y optimizar los procesos asistenciales del código ictus para reducir el riesgo de contagios y racionalizar el uso de recursos hospitalarios. Para ello, desde el Grupo Multidisciplinar Ictus Madrid proponemos una serie de recomendaciones. Métodos Revisión bibliográfica no sistemática de las publicaciones disponibles con los términos «stroke» y «COVID-19» o «coronavirus» o «SARS-CoV-2», así como otras conocidas por los autores. En base a esta se redacta un documento de recomendaciones que es sometido a consenso por el Grupo Multidisciplinar Ictus Madrid y su Comité de Neurología. Resultados Las recomendaciones se estructuran en cinco líneas fundamentales: 1) coordinar la actuación para garantizar el acceso a la asistencia hospitalaria de los pacientes con ictus; 2) reconocer a los pacientes con ictus potencialmente infectados por COVID-19, 3) organización adecuada para garantizar la protección de los profesionales sanitarios frente al riesgo de contagio por COVID-19, 4) en la realización de neuroimagen y otros procedimientos que conlleven contactos de riesgo de infección COVID-19 hay que procurar reducirlos y asegurar la protección, y 5) alta y seguimiento seguros procurando optimizar la ocupación hospitalaria. Resumimos el procedimiento de forma esquemática con el acrónimo CORONA (COordinar, Reconocer, Organizar, Neuroimagen, Alta). Conclusiones Estas recomendaciones pueden servir de apoyo para la organización del sistema sanitario en la atención al ictus agudo y la optimización de sus recursos, garantizando la protección de sus profesionalesThe COVID-19 pandemic has forced a reorganization of healthcare systems and an exceptional saturation of their resources. In this context, it is vital to ensure acute stroke care and optimize the care processes of the stroke code to reduce the risk of contagion and rationalize the use of hospital resources. To do this, the Ictus Madrid Multidisciplinary Group proposes a series of recommendations. Methods Non-systematic bibliographic review of the available publications with the terms «stroke» and «COVID-19» or «coronavirus» or «SARS-CoV-2», as well as other already known for the authors. We provide a document of recommendations as a result of the consensus of the Ictus Madrid Multidisciplinary Group and its Neurology Committee. Results Our recommendations are structured on five lines: (1) coordinate to guarantee the access to hospital care for stroke patients, (2) recognize potentially COVID-19 infected stroke patients, (3) organize to ensure the protection of healthcare professionals from COVID-19 infections, (4) neuroimaging and other procedures potentially associated to risks for COVID-19 infection should be reduced and secured to avoid contagion, and (5) at home as soon as possible and supported follow-up to optimize hospital occupancy. The procedure is shown summarized under the acronym CORONA (COordinate, Recognize, Organize, Neuroimaging, At home). Conclusions These recommendations can support the organization of healthcare services for acute stroke care and the optimization of their resources, guaranteeing the protection of healthcare professional

Clinical Course and Outcomes of Small Supratentorial Intracerebral Hematomas.

Intracerebral hemorrhage (ICH) volume, particularly if ≥30 mL, is a major determinant of poor outcome. We used a multinational ICH data registry to study the characteristics, course, and outcomes of supratentorial hematomas with volumes <30 mL.Basic characteristics, clinical and radiological course, and 30-day outcomes of these patients were recorded. Outcomes were categorized as early neurological deterioration (END), hematoma expansion, Glasgow Outcome Scale (GOS), and in-hospital death. Poor outcome was defined as composite of in-hospital death and severe disability (GOS ≤ 3). Comparison was conducted based on hemorrhage location. Logistic regression using dichotomized outcome scales was applied to determine predictors of poor outcome.Among 375 cases of supratentorial ICH with volumes <30 mL, expansion and END rates were 19.2% and 7.5%, respectively. Hemorrhage growth was independently associated with END (odds ratio: 28.7, 95% confidence interval [CI]: 8.51-96.5; P < .0001). Expansion rates did not differ according to ICH location. Overall, 13.9% (exact binomial 95% CI: 10.5-17.8) died in the hospital and 29.1% (CI: 24.5-34.0) had severe disability at 30 days; there was a cumulative poor outcome rate of 42.9% (CI: 37.9-48.1). Age, admission Glasgow Coma Scale, intraventricular extension, and END were independently associated with poor outcome. There was no difference in poor outcome rates between lobar and deep locations (40.2% versus 43.8%, P = .56).Patients with supratentorial ICH <30 mL have high rates of poor outcome at 30 days, regardless of location. Nearly 1 in 5 hematomas <30 mL expands, leading to END or death

Isolated Horner's syndrome caused by intraoral gunshot

A 45‐year‐old man developed Horner's syndrome after sustaining an intraoral gunshot in a suicide attempt. Examination did not show any major vascular injury or other neurological symptoms. Radiograph of the skull and helical computed tomography angiography of the brain and neck detected a bullet embedded in the interior of the left internal carotid artery (ICA) sheath. Surgical examination showed an intact left ICA. Horner's syndrome resulting from intraoral trauma rarely presents as an isolated sign and is generally associated with carotid injuries. It may herald a life‐threatening artery injury and needs urgent investigation

CholesteroNitrones for Stroke

This study describes CholesteroNitrone 2 as an antioxidant and neuroprotective agent against ischemic injury. Neuroprotection was assessed using in vitro and in vivo experimental ischemia models. The compound significantly increased cell viability, induced neuroprotection following ischemic reperfusion, and decreased neurological deficit scores in treated animals, supporting the next preclinical studies as a potential agent for the treatment of stroke.
