Análisis de la seguridad y efectividad a corto y medio plazo del tratamiento endovascular de las estenosis carotideas en función de la edad.
Introducción: Existe debate en la selección de los pacientes para la prevención del ictus isquémico en pacientes con estenosis carotidea, siendo la edad de los pacientes uno de los factores a considerar. Analizamos los resultados y seguridad del tratamiento endovascular en función de la edad en nuestro centro.
Material y métodos: Se realizó un estudio observacional descriptivo y analítico de una cohorte prospectiva con análisis retrospectivo de los pacientes tratados mediante angioplastia carotidea. Diferenciamos dos grupos según la edad: Grupo A (mayores de 75 años) y Grupo B (menores de 75). Analizamos la seguridad y efectividad, diferenciando entre precoz (a los 90 días) y tardía (al año) en el seguimiento.
Resultados: La población de estudio fueron 70 pacientes, de los cuales el 46.5% eran mayores de 75 años (grupo A). No hubo diferencias en las características basales de ambos grupos. Así como tampoco encontramos diferencias en la seguridad de la realización del procedimiento, ni en la evolución a corto y largo plazo en estos pacientes.
Conclusiones: En nuestros pacientes no hemos encontrado diferencias significativas en la seguridad y efectividad en la realización de angioplastia carotidea para la prevención del ictus isquémico en función de la edad
The current situation of Telestroke in Spain
[Resumen] Introducción. En los últimos años se ha establecido el uso del Teleictus como una herramienta fundamental para extender la atención a los pacientes con ictus agudo hasta hospitales que no disponen de neurólogos de guardia. El objetivo principal de este trabajo es describir la existencia y funcionamiento de los distintos sistemas y redes de Teleictus (ST) en España.
Método. Estudio transversal de la situación actual del Teleictus en España mediante la realización de una encuesta estructurada dirigida a los miembros del Grupo de Estudio de Enfermedades Cerebrovasculares de la Sociedad Española de Neurología.
Resultados. Han respondido a la encuesta desde 12 de las 17 comunidades autónomas, de las cuales 10 tenían ST. Además, en la búsqueda bibliográfica se han encontrado otros 2 sistemas funcionando. Doce de las 17 comunidades autónomas de España disponen de ST, consiguiendo una cobertura de al menos el 20% de la población española. De estos 10 ST, 7 tienen una organización regional, 2 provincial y otro, hospitalaria. En la mayoría de los ST (9) se realizan al menos TC simple y angio-TC, y en 4 ST también imagen de perfusión. Nueve ST funcionan con equipos de videoconferencia profesionales. Sin embargo, la calidad subóptima de la exploración por videoconferencia es el principal problema identificado en el 50% de los ST. Otros problemas detectados son la dificultad en la obtención de datos de los registros y la transferencia de imágenes entre hospitales.
Conclusión. En los últimos años, se ha observado una expansión significativa de los ST en España, lo que ha permitido mejorar la accesibilidad de la atención especializada en casos de síntomas de ictus agudo. Este estudio permite describir los diferentes tipos de ST en España, detectar áreas de mejora y crecimiento, y podría contribuir a definir estrategias regionales para implementar el Teleictus con el fin de ofrecer una atención de calidad a toda la población.[Abstract] Introduction. In recent years, Telestroke programmes have been established as a fundamental tool for extending acute stroke care to hospitals that lack an on-call neurology service. The main objective of this study is to describe the existence and functioning of the different Telestroke systems and networks (TS) in Spain.
Method. We conducted a cross-sectional study to analyse the current situation of TS in Spain using a structured survey distributed among the members of the Stroke Study Group of the Spanish Society of Neurology.
Results. Responses were received from 12 of the 17 Spanish autonomous communities, of which 10 had implemented TS. In addition, a literature search revealed that 2 other systems were in operation. Twelve of the 17 regions in the country have TS, achieving coverage of at least 20% of the Spanish population. Of these 10 TS, organisation was regional in 7, provincial in 2, and hospital-based in one. Most TS (9) included at least simple CT and angio-CT studies; 4 also included perfusion imaging. Nine TS operated with professional videoconferencing equipment. However, the suboptimal quality of examination via videoconferencing scan was the main problem identified in 50% of TS. Other problems detected are difficulty obtaining data from registries and the transfer of images between hospitals.
Conclusion. In recent years, a significant expansion of TS has taken place in Spain, which has improved the accessibility of specialised care in patients with symptoms of acute stroke. This study allows us to describe the different types of TS in Spain and to detect areas for improvement and expansion, and could contribute to defining regional telestroke implementation strategies to offer quality care to the whole population
A micellar formulation of quercetin prevents cisplatin nephrotoxicity
Producción CientíficaThe antioxidant flavonoid quercetin has been shown to prevent nephrotoxicity in animal models and in a clinical study and is thus a very promising prophylactic candidate under development. Quercetin solubility is very low, which handicaps clinical application. The aim of this work was to study, in rats, the bioavailability and nephroprotective efficacy of a micellar formulation of Pluronic F127-encapsulated quercetin (P-quercetin), with improved hydrosolubility. Intraperitoneal administration of P-quercetin leads to an increased plasma concentration and bioavailability of quercetin compared to the equimolar administration of natural quercetin. Moreover, P-quercetin retains overall nephroprotective properties, and even slightly improves some renal function parameters, when compared to natural quercetin. Specifically, P-quercetin reduced the increment in plasma creatinine (from 3.4 ± 0.5 to 1.2 ± 0.3 mg/dL) and urea (from 490.9 ± 43.8 to 184.1 ± 50.1 mg/dL) and the decrease in creatinine clearance (from 0.08 ± 0.02 to 0.58 ± 0.19 mL/min) induced by the nephrotoxic chemotherapeutic drug cisplatin, and it ameliorated histological evidence of tubular damage. This new formulation with enhanced kinetic and biopharmaceutical properties will allow for further exploration of quercetin as a candidate nephroprotector at lower dosages and by administration routes oriented towards its clinical use.Fundación de Universidades y Enseñanzas Superiores de Castilla y León (FUESCyL) y Banco de Santander - (grant: Ed. 2014– 2015 Desafío UNIV-EMP)Fundación General de la Universidad de Salamanca, Fondo Europeo de Desarrollo Regional (FEDER) y Junta de Castilla y León - (grant: Ed. 2015 Lanzadera TC)Junta de Castilla y León - (grant: VA225U14
High prevalence of obstructive sleep apnea syndrome in Spain’s Stroke Belt
[Objective] Spain’s so-called Stroke Belt is an area with high prevalence of vascular disease. We aimed to determine the prevalence of undetected obstructive sleep apnea–hypopnea syndrome (OSAHS) among patients with acute ischemic stroke (AIS) in southern Spain.[Methods] We conducted a cross-sectional study at the Virgen Macarena University Hospital Stroke Unit during 2018 to 2019. We included patients <72 hours after AIS with a neuroimaging lesion and performed sleep tests.[Results] Seventy-two patients were included. The median participant age was 72 years. Mean body mass index was 27.07 kg/m2, and 40.28% were daily alcohol drinkers. Hypertension, atrial fibrillation, ischemic cardiomyopathy, and previous stroke were detected in 63.9%, 11.1%, 15.3%, and 17.6% of patients, respectively. Polygraphy was feasible in 91.38% of patients. The prevalence of OSAHS was 84.72% (apnea–hypopnea index ≥5). Patients with moderate and severe OSAHS were more likely to be obese and to have a larger neck circumference and facial palsy. The diagnostic criteria of central sleep apnea syndrome were met in only 1.38% of patients.[Conclusions] The high prevalence of OSAHS found in the Spanish Stroke Belt justifies further investigation and development of a screening program as a strategy to identify patients with undetected OSAHS.The authors disclosed receipt of the following financial support for the research, authorship and/or publication of this article: This work was supported by the Neurovascular Research Group, part of the Cooperative Cerebrovascular Disease Research Network (INVICTUS+) (RD16/0019/0015).Peer reviewe
Manual municipal sobre control de vertidos
El agua, como motor de desarrollo y fuente de riqueza, ha constituido uno de los pilares fundamentales para el progreso del hombre. La ordenación y gestión de los recursos hídricos, que ha sido desde siempre un objetivo prioritario para cualquier sociedad, se ha realizado históricamente bajo directrices orientadas a satisfacer la demanda en cantidades suficientes, bajo una perspectiva de política de oferta.
El incremento de la oferta de agua como herramienta para el impulso económico, el mayor nivel de contaminación, irremisiblemente asociado a un mayor nivel de desarrollo, algunas características naturales (sequías prolongadas, inundaciones) y en definitiva una sobreexplotación de los recursos hídricos, han conducido a un deterioro importante de los mismos.
El desarrollo de la Directiva Europea y Nacional respecto a control de vertido responsabiliza al Ayuntamiento directamente de los vertidos del municipio al exterior, y consecuentemente al Alcalde Presidente de cada Municipio. Por ello la Diputación de Sevilla, cumpliendo su labor de auxilio técnico al municipio ha encargado al Grupo TAR este manual municipal de control de vertidos para asesorar continuamente a todos los pueblos de la provincia de Sevilla, con la vocación de que sea una herramienta permanente de consulta que ayude a conseguir que la provincia lidere el cumplimiento de las normas y el desarrollo sostenible de todo su entorno.
Real Decreto Legislativo 1/2001, de 20 de julio, por el que se aprueba el texto refundido de la Ley de Aguas de 1.985, junto con la nueva Directiva Marco europea para la política de agua suponen un cambio importante en los conceptos y criterios utilizados en la planificación hidrológica e introducen la calidad de las aguas y la protección de los recursos hídricos como puntos fundamentales para estructurar dicha planificación.
El estado ecológico de un agua sería una expresión de la calidad de la estructura y del funcionamiento del ecosistema y cuyos criterios de clasificación (muy bueno, bueno y aceptable), en función del tipo de ecosistema acuático de que se trate, se recogen en los anexos de la directiva
Relevance of Carotid Reocclusion in Tandem Lesions
© 2023 Japan Atherosclerosis Society. This article is distributed under the terms of the latest version of CC BY-NC-SA defined by the Creative Commons Attribution License.Aims: Carotid reocclusion (CRO) after mechanical thrombectomy (MT) in acute ischemic stroke (AIS) due to tandem lesion (TL) or isolated internal carotid occlusion (ICO) is associated with worse clinical outcomes. Our aim was to analyze the predictors and clinical impact of CRO. Methods: A retrospective single-center analysis of all patients with anterior circulation strokes who underwent MT prospectively included in a registry between 2017 and 2020 was performed. ICO and TL as stroke causes were included. Stent deployment was left to the discretion of the interventionist. All patients received at least intravenous aspirin during MT. CRO was assessed using ultrasound within the first 24 h after MT. Efficacy and safety of stenting were assessed.
Results: Among 1304 AIS cases, 218 (16.7%) were related to TL or ICO. Of them, 5% (n=11) were associated with internal CRO 24 h after the endovascular procedure. After adjusting per confounders, multivariate analysis showed that the independent variables associated with CRO were the TICI recanalization grade [TICI 2b–3; OR 0.1, 95% confidence interval (CI) 0.01–0.89, p=0.040], pial collateral circulation presence (OR 0.09, 95% CI 0.02–0.45, p=0.03), stent deployment during MT (OR 0.17, 95% CI 0.03–0.84, p=0.030), and general anesthesia use (OR 2.92, 95% CI 1.13–7.90, p=0.034). CRO showed a trend toward worst outcomes (modified Rankin scale 3–6) at 3 months (OR 3.4, 95% CI 0.96–12, p=0.057). After multivariate analysis, variables independently associated with worse outcomes at 90 days were intrastent platelet aggregation phenomena during endovascular therapy, admission National Institute of Health Stroke Scale, and age. Conversely, intravenous thrombolysis and TICI 2b–3 recanalization grade were identified as independent predictors of good outcomes at 90 days. Conclusions: CRO has a relevant clinical impact in our study, associating lower rates of good functional outcomes at 3 months. Independent factors of CRO were the recanalization degree, presence of pial collateral circulation, use of a stent as a protective factor, and use of general anesthesia during thrombectomy.This project was funded by the Instituto de Salud Carlos III (ISCIII) through the project PI21/01322 and co-funded by the European Union.

Tarteso. Nuevas Fronteras (II)
El presente volumen recoge las contribuciones presentadas al II Congreso Internacional sobre Tarteso, Nuevas Fronteras, que tuvo lugar en Mérida entre los días 17 y 19 de noviembre de 2021. Su lectura permite un viaje desde el extremo oriental del Mediterráneo hasta el suroeste de la península ibérica, mostrando las diversas realidades históricas acontecidas en este territorio durante la I Edad del Hierro. El objetivo de esta publicación es mostrar la situación que atravesaba el Mediterráneo durante los años de surgimiento y desarrollo de la cultura tartésica para así comprender mejor la formación y evolución de dicha cultura. El conocimiento de Tarteso ha evolucionado sensiblemente en la última década, desde la celebración y publicación de las actas del I Congreso Internacional, Tarteso. El emporio del metal (Almuzara, 2013). La incorporación de nuevas voces y visiones enfocadas al conocimiento de la protohistoria peninsular, así como de algunos temas nunca antes abordados en el conocimiento de Tarteso, permiten presentar en este volumen una visión renovada, donde destaca la incorporación de unos nuevos límites territoriales para esta cultura.Esta publicación se ha beneficiado de las siguientes ayudas para su financiación:

Efficacy of clozapine versus standard treatment in adult individuals with intellectual disability and treatment-resistant psychosis (CLOZAID): study protocol of a multicenter randomized clinical trial
BackgroundIntellectual disability (ID) affects approximately 1% of the worldwide population and individuals with ID have a higher comorbidity with mental illness, and specifically psychotic disorders. Unfortunately, among individuals with ID, limited research has been conducted since ID individuals are usually excluded from mental illness epidemiological studies and clinical trials. Here we perform a clinical trial to investigate the effectiveness of clozapine in the treatment of resistant psychosis in individuals with ID. The article highlights the complexity of diagnosing and treating psychopathological alterations associated with ID and advocates for more rigorous research in this field.MethodsA Phase IIB, open-label, randomized, multicenter clinical trial (NCT04529226) is currently ongoing to assess the efficacy of oral clozapine in individuals diagnosed with ID and suffering from treatment-resistant psychosis. We aim to recruit one-hundred and fourteen individuals (N=114) with ID and resistant psychosis, who will be randomized to TAU (treatment as usual) and treatment-with-clozapine conditions. As secondary outcomes, changes in other clinical scales (PANSS and SANS) and the improvement in functionality, assessed through changes in the Euro-QoL-5D-5L were assessed. The main outcome variables will be analyzed using generalized linear mixed models (GLMM), assessing the effects of status variable (TAU vs. Clozapine), time, and the interaction between them.DiscussionThe treatment of resistant psychosis among ID individuals must be directed by empirically supported research. CLOZAID clinical trial may provide relevant information about clinical guidelines to optimally treat adults with ID and treatment-resistant psychosis and the benefits and risks of an early use of clozapine in this underrepresented population in clinical trials.Trial registrationClinicaltrials.gov: NCT04529226.

Dietary α‐Linolenic Acid, Marine ω‐3 Fatty Acids, and Mortality in a Population With High Fish Consumption: Findings From the PREvención con DIeta MEDiterránea (PREDIMED) Study
Background: Epidemiological evidence suggests a cardioprotective role of α‐linolenic acid (ALA), a plant‐derived ω‐3 fatty acid. It is unclear whether ALA is beneficial in a background of high marine ω‐3 fatty acids (long‐chain n‐3 polyunsaturated fatty acids) intake. In persons at high cardiovascular risk from Spain, a country in which fish consumption is customarily high, we investigated whether meeting the International Society for the Study of Fatty Acids and Lipids recommendation for dietary ALA (0.7% of total energy) at baseline was related to all‐cause and cardiovascular disease mortality. We also examined the effect of meeting the society's recommendation for long‐chain n‐3 polyunsaturated fatty acids (≥500 mg/day). Methods and Results: We longitudinally evaluated 7202 participants in the PREvención con DIeta MEDiterránea (PREDIMED) trial. Multivariable‐adjusted Cox regression models were fitted to estimate hazard ratios. ALA intake correlated to walnut consumption (r=0.94). During a 5.9‐y follow‐up, 431 deaths occurred (104 cardiovascular disease, 55 coronary heart disease, 32 sudden cardiac death, 25 stroke). The hazard ratios for meeting ALA recommendation (n=1615, 22.4%) were 0.72 (95% CI 0.56–0.92) for all‐cause mortality and 0.95 (95% CI 0.58–1.57) for fatal cardiovascular disease. The hazard ratios for meeting the recommendation for long‐chain n‐3 polyunsaturated fatty acids (n=5452, 75.7%) were 0.84 (95% CI 0.67–1.05) for all‐cause mortality, 0.61 (95% CI 0.39–0.96) for fatal cardiovascular disease, 0.54 (95% CI 0.29–0.99) for fatal coronary heart disease, and 0.49 (95% CI 0.22–1.01) for sudden cardiac death. The highest reduction in all‐cause mortality occurred in participants meeting both recommendations (hazard ratio 0.63 [95% CI 0.45–0.87]). Conclusions: In participants without prior cardiovascular disease and high fish consumption, dietary ALA, supplied mainly by walnuts and olive oil, relates inversely to all‐cause mortality, whereas protection from cardiac mortality is limited to fish‐derived long‐chain n‐3 polyunsaturated fatty acids.
