Abstract

RESUMEN Introducción: Las bradiarritmias persistentes que requieren el implante de un marcapasos definitivo son una complicación frecuente tras el implante valvular aórtico percutáneo (IVAP), pero un implante alto con técnica Cusp-Overlap podría evitar las alteraciones del sistema de conducción. Objetivo: El objetivo fue determinar la tasa de uso de marcapasos en pacientes que recibieron IVAP con la técnica convencional coplanar en comparación con Cusp-Overlap. Material y métodos: Entre 2017 y 2019 se analizaron 65 pacientes consecutivos de dos centros, que recibieron válvulas EvolutR o Evolut-Pro: 50 implante coplanar y 15 Cusp-Overlap. Resultados: La edad promedio era 80 años y no hubo diferencias en el riesgo por puntaje EuroSCORE. Los procedimientos con la técnica de Cusp-Overlap presentaron 0% de requerimiento de marcapasos en comparación con 24,9% en el implante convencional (p = 0,041). También hubo menos complicaciones mayores (6,67% vs 42%; OR = 0,09; IC 95% 0,01-0,8; p = 0,011). Conclusiones: En esta cohorte el IVAP con la técnica de Cusp-Overlap se asoció con una necesidad de marcapasos nula. Dado el potencial impacto a gran escala se necesita validar externamente los resultados obtenidos. ABSTRACT Background: Persistent bradyarrhythmias requiring permanent pacemaker implantation are a common complication after transcatheter aortic valve implantation (TAVI), but high implantation with cusp-overlap technique could prevent conduction system disturbances. Objective: The aim of this study was to assess the rate of pacemaker use in patients who received TAVI with conventional coplanar technique compared with cusp-overlap technique. Methods: A total of 65 consecutive patients from two centers receiving Evolut-R or Evolut-Pro valve implantation, 50 coplanar and 15 cusp-overlap, were analyzed between 2017 and 2019. Results: Mean age was 80 years, and there were no differences in risk according to the EuroSCORE. The rate of pacemaker requirement was 0% in cusp-overlap procedures compared with 24.9% in those with conventional implantation; p=0.041). In addition, cusp-overlap implants presented lower rate of major complications (6.67% vs. 42%; OR=0.09; 95% CI 0.01-0.8; p=0.011). Conclusions: In this cohort, TAVI procedure with cusp-overlap technique was associated with null pacemaker requirement. Given the potential large-scale impact, external validation of results is needed.

Abstract

RESUMEN Objetivos: La bibliometría es un tipo de estudio estadístico sobre datos científicos. Mediante esta herramienta queremos valernos para visualizar distintos aspectos que presentan los medicamentos biosimilares, su importancia y el impacto que generan en su entorno. Métodos: se ha utilizando como motor de búsqueda Science Direct, así como de publicaciones científicas referenciadas en la bibliografía y como de algunas webs sobre la materia. Resultados: Casi todos los indicadores señalan la gran importancia económica que concierne entorno a los medicamentos biosimilares, la actualidad que presenta y que gran parte de su estudio se concentra alrededor de los pacientes. Conclusiones: Con este trabajo se comprueba el gran interés que ofrecen los biosimilares y sobre todo el impacto que tendrán en un futuro, así como las repercusiones que traerán consigo, sobre todo en los campos económicos y de la salud. ABSTRACT Objectives: A bibliometrics study is a type of statistical study on scientific data. With this tool we want to visualize different aspects of biosimilar drugs, their importance and the impact they generate in their environment. Methods: Science Direct was utilized as a search engine, in addition to the scientific publications referenced in the bibliography as well as some websites concerning the subject. Results: Almost all the indicators point to the great economic importance of biosimilar drugs, their novelty and their patient-coentered focus. Conclusions: It is of great interest to know the future impact that these medicines will have and the repercussions they will bring, especially in the economic and health fields.

Abstract

Exogenous neuroprotective protein neuroglobin (Ngb) cannot cross the blood–brain barrier. To overcome this difficulty, we synthesized hyaluronate nanoparticles (NPs), able to deliver Ngb into the brain in an animal model of stroke (MCAO). These NPs effectively reached neurons, and were microscopically identified after 24 h of reperfusion. Compared to MCAO non-treated animals, those treated with Ngb-NPs showed survival rates up to 50% higher, and better neurological scores. Tissue damage improved with the treatment, but no changes in the infarct volume or in the oxidative/nitrosative values were detected. A proteomics approach (p-value < 0.02; fold change = 0.05) in the infarcted areas showed a total of 219 proteins that significantly changed their expression after stroke and treatment with Ngb-NPs. Of special interest, are proteins such as FBXO7 and NTRK2, which were downexpressed in stroke, but overexpressed after treatment with Ngb-NPs; and ATX2L, which was overexpressed only under the effect of Ngb. Interestingly, the proteins affected by the treatment with Ngb were involved in mitochondrial function and cell death, endocytosis, protein metabolism, cytoskeletal remodeling, or synaptic function, and in regenerative processes, such as dendritogenesis, neuritogenesis, or sinaptogenesis. Consequently, our pharmaceutical preparation may open new therapeutic scopes for stroke and possibly for other neurodegenerative pathologies. [ABSTRACT FROM AUTHOR]
