Ischaemic Stroke in the Time of Coronavirus Disease 2019

Each year, between 1.1 and 1.5 million Europeans have a stroke1. Two to three out of 10 patients die as a consequence of it and about one third remains functionally dependent2. As we know, the likelihood of a favourable outcome in this disease relies heavily on patients presenting promptly after symptoms onset and on hospitals providing immediate access to optimized stroke care

A randomized study of nutritional supplementation in patients with unilateral wet age-related macular degeneration

The purpose of this study is evaluate the efficacy and safety of medicinal products con-taining the original Age-Related Eye Disease group (AREDS) formulation at doses approved in Europe (EU, control group; n = 59) with a product that adds DHA, lutein, zeaxanthin, resveratrol and hydroxytyrosol to the formula (intervention group; n = 50). This was a multicenter, random-ized, observer-blinded trial conducted in patients aged 50 years or older diagnosed with unilateral exudative Age related Macular Degeneration AMD. At month 12, the intervention did not have a significant differential effect on visual acuity compared with the control group, with an estimated treatment difference in Early Treatment Diabetic Retinopathy Study (ETDRS) of -1.63 (95% CI -0.83 to 4.09; p = 0.192). The intervention exhibited a significant and, in most cases, relevant effect in terms of a reduction in some inflammatory cytokines and a greater improvement in the fatty acid profile and serum lutein and zeaxantin concentration. In patients with unilateral wet AMD, the addition of lutein, zeaxanthin, resveratrol, hydroxytyrosol and DHA to the AREDS EU recommended doses in the short-term did not have a differential effect on visual acuity compared to a standard AREDS EU formula but, in addition to improving the fatty acid profile and increasing carotenoid serum levels, may provide a beneficial effect in improving the proinflammatory and proangiogenic profile of patients with AMD. © 2021 by the authors.

Distrofia miotónica tipo 1: 13 años de experiencia en un hospital terciario. Estudio clínico y epidemiológico. Correlación genotipo-fenotipo

Resumen: Introducción: Se desconoce la incidencia de la distrofia miotónica tipo 1 (DM1), enfermedad con gran variedad fenotípica, en nuestra región. El objetivo de nuestro trabajo es estimar la incidencia de DM1 en nuestro centro (referencia en Aragón) e identificar las características propias de nuestra población (correlación genotipo-fenotipo). Métodos: Estudio descriptivo retrospectivo de 459 pacientes clasificados según número de repeticiones CTG en: normal (5-35), premutado (36-50), protomutado (51-80), pequeñas expansiones (81-150), intermedias (151-1.000) y grandes (> 1.000). Además, según el fenotipo mostrado, se categorizaron como: no afectos (5-50 CTG), forma leve o asintomática (51-150 CTG), clásica (151-1.000 CTG) y severa (> 1.000 CTG). Resultados: La incidencia de DM1 fue de 20,61 (IC 95%: 19,59-21,63) casos por millón de individuos-año. Se evidenció una correlación inversa entre el número de CTG y la edad al diagnóstico genético (ρ = −0,547; IC 95%: −0,610 a −0,375; p  1000). Furthermore, according to clinical phenotype, patients were categorised as unaffected (5-50 CTG repeats), mild form or asymptomatic (51-150), classical form (151-1000), and severe form (> 1000). Results: The incidence of DM1 was 20.61 cases per million person-years (95% CI: 19.59-21.63). An inverse correlation was observed between the number of CTG repeats and the age at genetic diagnosis (ρ = −0.547; 95% CI: −0.610 to −0.375; P < .001). CTG5 was the most frequent polymorphic allele in healthy individuals. Of all patients with DM1, 28.3% presented the mild or asymptomatic form, 59.1% the classical form, and 12.6% the severe form. Inheritance was maternal in 35.1% of cases, paternal in 59.4%, and uncertain in 5.5%. In mild forms, frontal balding in men was the most prevalent phenotypic trait, as well as myotonia and cataracts, while in the classical form, ptosis, facial weakness, voice and pronunciation alterations, myotonia, and fatigue/sleepiness were most frequent. Conclusions: The incidence of DM1 in Aragon is significant. Multidisciplinary study of the phenotype of patients with DM1 is key to early diagnosis and personalised management
