Comparison of First-Pass Effect in Aspiration vs. Stent-Retriever for Acute Intracranial ICA Occlusion.

The purpose of this study is to evaluate the best endovascular approach (aspiration or stent-retriever) and the impact of stent retriever size and length on clinical and angiographic outcomes in patients with acute intracranial ICA occlusion. We conducted a retrospective analysis of a prospective database of consecutive patients with acute intracranial ICA occlusion undergoing endovascular treatment in four Comprehensive Stroke Center between June-2019 and December-2020. We include 121 patients; Stent-retriever (SR) was used as first technical approach in 107 patients (88.4%) and aspiration was used in 14 patients (11.6%). SR group had higher rate of FPE compared to aspiration group (29 vs. 0%, p = 0.02). In SR subgroup, treatment highlighted higher FPE in the 6 × 50 SR (37.7%), than in the rest of the SR which are 21.2% (4-5 mm size and 20-50 mm length SR) and 19% (6 mm size and 25-40 mm length SR), but it was not found to be statistically significant. There were no other significant differences across the groups regarding primary angiographic or clinical outcomes. In our intracranial ICA occlusion series, stent retrievers were superior to direct aspiration in obtaining FPEs and mFPEs, and longer devices achieved better results with no statistically significant difference. Further studies evaluating the effects of different ICA clot removal approaches are warranted to confirm these results.

Distal Transradial Artery Access for Neuroangiography and Neurointerventions : Pitfalls and Exploring the Boundaries.

INTRODUCTION: The distal transradial approach (dTRA) is progressively gaining more clinical use in the fields of cardiology and other vascular interventions, as it offers a number of advantages compared to conventional radial approach (TRA). These include lower rates of vascular occlusion which permits preservation of the proximal radial artery for future procedures in the event of a distal occlusion. AIM: To share the experience in the use of dTRA for neurointerventions, showing its advantages, pitfalls as well as sharing our optimized puncture and hemostatic ultrarapid compression protocols to improve the use of this vascular access. METHODS: A retrospective analysis of our experience of diagnostic and interventional procedures performed via dTRA using an optimized protocol for puncture and postpuncture compression of the dTRA was performed. The rate of complications (hematoma and arterial dissection at puncture site) femoral crossover, and assessment of postprocedural stenosis/occlusion with the ultrarapid compression protocol were also assessed. RESULTS: From March 2019 to July 2020 a total of 100 distal radial procedures were carried out and 53 diagnostic angiograms (53%) and 47 interventional procedures (47%) were included in the analysis. We achieved a 96% technical success, with a femoral crossover requirement in 3 cases (3%), and one conventional TRA crossover due to puncture failure. Of the patients 3 presented puncture site hematomas (3%) with no intervention required, 61 patients (61%) underwent the ultrarapid hemostasis protocol in association with a hemostatic pad. Ultrasound follow-up was performed in 20 patients (20%) at 1-2 months with 1 case of occlusion (5%) and 2 of radial stenosis (10%). In all 3 cases proximal radial artery remained patent. CONCLUSION: The dTRA is a safe and feasible access route for angiography and neurointerventions. Using vasodilators prepuncture, we attained a variable increase in the vascular diameter facilitating puncture and reducing the risk of occlusion and vascular spasm. A rapid deflation protocol for postpuncture hemostasis does not significantly increase the hematoma rate.

Irena Sendler, La Enfermera Salvadora Del Gueto De Varsovia / Irena Sendler, the saving nurse of childrens of warsaw Ghetto

El objetivo del presente artículo es hacer un resumen de la vida de Irena Sendler, una enfermeraque salvó a más de 2500 niños durante la II Guerra Mundial y cuya hazaña es prácticamentedesconocida para la mayor parte de la población en general. La figura de Irena Sendler debe sermás conocida por parte de todo el mundo, ya que puede servir como motivación para queenfermeros y población en general valoren la protección de la vida sin esperar nada a cambio.Para llevar a cabo este artículo se ha realizado una revisión bibliográfica en diferentes bases dedatos, como CINAHL, CUIDEN o SCOPUS, así como algunos libros relacionados con el tema. A pesarde ser una figura importante para la vida de muchas personas, no se encontraron muchaspublicaciones sobre Irena Sendler. Con las obtenidas, se creó una biografía sobre ella. Irena Sendler representa uno de los ejemplos más claros de que la Enfermería no sólo protege la vidadentro de un hospital, sino que se extiende a cualquier ámbito y a cualquier lugar.

Tumores cerebrales infratentoriales y supratentoriales: comparación de perfil cognitivo y su impacto en la calidad de vida en niños en edad escolar / Infra- and supratentorial brain tumors: comparison of the cognitive profile and its impact on quality of life in school-age children

INTRODUCCION: Los avances científicos han logrado aumentar la cantidad de pacientes pediátricos que sobreviven a enfermedades oncológicas. En general, para los niños que padecen tumores del sistema nervioso central, esta sobrevida viene acompañada de efectos adversos secundarios, tales como déficits cognitivos.OBJETIVO: Evaluar las funciones cognitivas y la calidad de vida en niños con tumores cerebrales infratentoriales y supratentoriales.METODOS: Se realizó un estudio analítico observacional. La muestra total estuvo conformada por 51 sujetos. Se utilizaron los siguientes instrumentos de medición: Escala de Inteligencia de Wechsler para niños IV, Sistema de Evaluación Cognitiva; Test de Memoria y Aprendizaje; Escala Graffar y Peds Quality of Life 4.0.RESULTADOS: La comparación de los resultados no arrojó diferencias significativas entre localizaciones tumorales infratentoriales y supratentoriales. La totalidad de los pacientes evaluados en un período de post-tratamiento oncológico presentó un descenso similar y significativo en todas las áreas estudiadas, en relación con lo esperado para la población general. Las funciones cognitivas que evidenciaron mayor compromiso fueron la velocidad de procesamiento y la capacidad atencional (principalmente en tareas de planificación). Los resultados observados pusieron de manifiesto estos déficits, así como un alto compromiso de la calidad de vida escolar.CONCLUSIONES: El trabajo se presenta como un estudio preliminar. A partir de él se podría definir la tendencia general del estado neurocognitivo, analizar su impacto en la calidad de vida de la población estudiada y plantear interrogantes dirigidos a futuras investigaciones.

INTRODUCTION: Due to scientific advances, there is a growing number of pediatric patients surviving cancer. In general, for children who suffer from central nervous system tumors, this survival is associated with secondary adverse effects, such as cognitive deficits.OBJECTIVE: To assess cognitive functions and quality of life in children with infratentorial and supratentorial brain tumors.METHODS: An analytical observational study was conducted. The total sample consisted of 51 subjects. Following measurement instruments were used: Wechsler Intelligence Scale for Children, Fourth Edition (WISC IV), Cognitive Assessment System (CAS), Test of Memory and Learning (TOMAL), Graffar Scale and Peds Quality of Life 4.0.RESULTS: The comparisons of the results did not show significant differences between infratentorial and supratentorial tumor location. All patients that were evaluated in the post-cancer treatment period revealed a similar significant impairment in all the areas studied, when compared with the level expected in the general population. The most severely affected cognitive functions were processing speed and attention span, mainly on planning tasks. The findings also showed that quality of life at school is severely affected in these children.CONCLUSIONS: This is a preliminary study whose results may define a general trend of neurocognitive status, analyzing its impact on the quality of life of the study population and posing useful questions for the future research.
