Tendencies in cerebral aneurism treatment: Analysis of a hospital series

Introduction and objective: To discover if there have been changes in the treatment time for SAH in our hospital environment. Material and methods: Comparative analysis of 571 patients treated at Hospital Universitari la Fe during 2 different time periods. The SAH-OLD group consisted of 462 patients attended consecutively between April 1997 and March 2005, while SAH-NEW comprised 109 patients attended consecutively between March 2007 and April 2010. We analysed demographic factors, risk factors, severity at time of admission, time to arteriography, diagnosis of aneurysm, use of surgical or endovascular treatment and time to treatment, frequency of neurological complications, in-hospital deaths, and modified Rankin Scale (mRS) at discharge. Results: Mean time to arteriography was 2.18 ± 2.5 days for the SAH-OLD group and 2.37 ± 2.23 days, for the SAH-NEW group (P = .49). Mortality rates for SAH-OLD patients were calculated at 30%, compared to 18.3% in SAH-NEW patients (P = .01).Among patients surviving the hospital stay in the SAH-OLD group, 13.3% had an mRS > 3, compared to 21.3% of survivors in the SAH-NEW group (P = .06). Two hundred forty-five patients in the SAH-OLD group had cerebral aneurysms and 208 were treated (45% of the patient total). Sixty-five of the SAH-NEW patients received treatment (60% of the patient total, P = .007). In the SAH-OLD group, 62.9% of the patients underwent embolisation vs 74.6% in the SAH-NEW group (P = .08). Time to embolisation was 4.7 ± 8.2 days for SAH-OLD patients and 2.12 ± 2.2 days for SAH-NEW patients (P = .01). Twenty-two percent of SAH-OLD patients underwent surgery, compared to 25.4% in the SAH-NEW group (P = .62). Conclusions: Care for SAH patients has improved in this hospital: results include fewer mortalities, a higher number of treatments with a smaller proportion of endovascular treatments, and shorter times to treatment. Elapsed time to arteriography remains stable. Resumen: Introducción y objetivo: Conocer, en nuestro medio, si ha habido variaciones en el tiempo en la atención a la HSA. Material y métodos: Análisis de 571 pacientes con HSA tratados en el Hospital Universitario La Fe.Comparación de 2 periodos: HSA-VIEJA: 462 pacientes consecutivos atendidos entre abril del 1997 y marzo del 2005; HSA-NUEVA: 109 pacientes consecutivos atendidos entre marzo del 2007 y abril del 2010. Se analizaron las características demográficas, los factores de riesgo, la gravedad al ingreso, los tiempos hasta la arteriografía, el diagnóstico de aneurisma, el tratamiento quirúrgico o intravascular y sus tiempos, frecuencia de complicaciones neurológicas, la mortalidad durante el ingreso y escala de Rankin modificada (mRS) al alta. Resultados: Media hasta la realización de la arteriografía: HSA-VIEJA: 2,18 ± 2,5 días, HSA-NUEVA: 2,37 ± 2,23 días, p = 0,49. Mortalidad: HSA-VIEJA 30% frente al 18,3% en HSA-NUEVA, p = 0,01. Entre los supervivientes al alta hospitalaria, un 13,3% en HSA-VIEJA tenía mRS > 3 frente a un 21,3% en HSA-NUEVA, p = 0,06. HSA-VIEJA: 245 pacientes tenían aneurisma cerebral, se trataron 208 (45% del total de los pacientes); HSA-NUEVA: reciben tratamiento 65 (60% del total de los pacientes), p = 0,007. HSA-VIEJA: se embolizaron 62,9%, HSA-NUEVA: 74,6%, p = 0,08. HSA-VIEJA: cirugía 22%, HSA-NUEVA: 25,4%, p = 0,62. Conclusiones: En nuestro hospital ha mejorado la atención a la HSA: menor mortalidad, mayor número de tratamientos a expensas del tratamiento intravascular y menor tiempo hasta el tratamiento. El tiempo hasta la arteriografía ha permanecido estable.

The width of the third ventricle associates with cognition and behaviour in motor neuron disease

Objectives: An enlarged width of the third ventricle (WTV) has been described in amyotrophic lateral sclerosis (ALS) patients, although its clinical meaning is unknown. The aims of this study were to evaluate the contribution of demographical, clinical and genetic factors to the WTV in different motor neuron disease (MND) phenotypes and to assess its brain structural correlates. Materials and methods: The WTV was measured by transcranial ultrasound in 107 MND patients (82 diagnosed with classical ALS, 16 with progressive muscular atrophy and 9 with primary lateral sclerosis) and 25 controls. Genetic analysis, and neurological and neuropsychological examinations were performed in patients. Brain volumetric analysis of MR images was obtained in 85 patients. The association of WTV with demographical, clinical, genetic and neuropsychological variables as well as with brain volumes was assessed by multivariable models. Results: Eighteen patients were diagnosed with genetic MND and 42.3% of patients showed executive or behavioural impairment (EBI). MND patients showed larger WTV than controls. The WTV was significantly associated with age, spinal onset and the presence of EBI, but not with the genetic background, the phenotype or disability. Greater WTV was also associated with reduced subcortical grey matter volume, but not with the cortical or the white matter volume. Conclusions: The enlargement of the WTV found in the different MND phenotypes is attributable to the subcortical grey matter atrophy and is associated with cognitive and behavioural impairment. Larger longitudinal studies are needed to determine its role as biomarker in MND patients with frontotemporal dementia.JFVC is funded by the Instituto de Salud Carlos III (ISCIII).

Inhibidores de la proproteína convertasa subtilisina/kexina tipo 9 (iPCSK9) en la prevención secundaria de episodios vasculares en pacientes con ictus isquémico: Documento de consenso y aplicaciones prácticas

Introducción Los pacientes, tras un ictus o un ataque isquémico transitorio, presentan un riesgo muy elevado de sufrir nuevos episodios vasculares. La reducción del nivel de colesterol unido a lipoproteínas de baja densidad (cLDL) reduce la incidencia de nuevos episodios, si bien una proporción importante de pacientes no alcanza los objetivos terapéuticos recomendados con los tratamientos hipolipemiantes actuales. El objetivo de este documento de consenso es actualizar el papel de los inhibidores de la proproteína convertasa subtilisina/kexina tipo 9 (iPCSK9; alirocumab y evolocumab) en la prevención secundaria de episodios vasculares en pacientes con ictus isquémico previo. Métodos Se realizó una revisión bibliográfica para identificar las principales evidencias sobre el uso de iPCSK9 en estos pacientes y los objetivos terapéuticos recomendados de cLDL. Los resultados se discutieron en 2 reuniones de consenso, que constituyeron la base para la elaboración del documento. Conclusiones Los iPSCSK9 son eficaces en la reducción del riesgo vascular en prevención secundaria y, específicamente, evolocumab ha demostrado esta reducción en pacientes con ictus isquémico previo. Ambos fármacos han demostrado un buen perfil de seguridad, incluso en pacientes que alcanzaron un nivel de cLDL < 20 mg/dL. En este sentido, en el subestudio de episodios neurocognitivos con evolocumab no se observó ninguna señal de empeoramiento de la función cognitiva en pacientes con nivel muy bajo de cLDL. Con base en estas evidencias, en el documento se presentan recomendaciones prácticas sobre el uso de iPCSK9 para la prevención secundaria y seguimiento de episodios vasculares en pacientes con ictus isquémico previo
