Citicoline in the treatment of acute ischaemic stroke: an international, random...
Dávalos, A; Alvarez-Sabin, J; Castillo, J; Diez-Tejedor, E; Ferro, J; Martinez-Vila, E; Serena, J; Segura, T; Cruz, V; Masjuan, J; Cobo, E; Secades, JBACKGROUND: Citicoline is approved in some countries for the treatment of acute ischaemic stroke. The drug has shown some evidence of efficacy in a pooled analysis. We sought to confirm the efficacy of citicoline in a larger trial. METHODS: We undertook a randomised, placebo-controlled, sequential trial in patients with moderate-to-severe acute ischaemic stroke admitted at university hospitals in Germany, Portu...
The role of ADH1B in alcohol consumption and stroke susceptibility
Paulos-Pinheiro, S.; Coelho, J.I.; Albergaria, I.; Gaspar, G.; Ferro, J.M.; Vicente, A.M.This work was part of a collaboration between Grupo de Neurogenética e Saúde Mental, Departamento de Promoção da Saúde e Prevenção de Doenças Não Transmissíveis, INSA, Lisboa, and Genetic Epidemiology Group, Department of Epidemiology and Public Health, University College of London, London. Samples collection was supported by fellowship PECS/T/SAU/179/95, from Fundação para a Ciência e a Tecnologia (FCT; Portug...
Genetic risk factors for ischaemic stroke and its subtypes (the METASTROKE coll...
Traylor, M.; Farrall, M.; Holliday, E.G.; Sudlow, C.; Hopewell, J.C.; Cheng, Y.C.; Fornage, M.; Ikram, M.A.; Malik, R.; Bevan, S.; Thorsteinsdottir, U.Various genome-wide association studies (GWAS) have been done in ischaemic stroke, identifying a few loci associated with the disease, but sample sizes have been 3500 cases or less. We established the METASTROKE collaboration with the aim of validating associations from previous GWAS and identifying novel genetic associations through meta-analysis of GWAS datasets for ischaemic stroke and its subtypes.
Self-perceived memory complaints predict progression to Alzheimer disease: The ...
Verdelho, A.; Madureira, S.; Moleiro, C.; Santos, A.C.; Ferro, J.; Erkinjuntti, T.; Poggesi, A.; Pantoni, L.; Fazekas, F.; Scheltens, P.; Waldemar, G.WOS:000280103900012 (Nº de Acesso Web of Science) ; “Prémio Científico ISCTE-IUL 2012” ; Memory complaints are frequent in the elderly but its implications in cognition over time remain a controversial issue. Our objective was to evaluate the risk of self perceived memory complaints in the evolution for future dementia. The LADIS (Leukoaraiosis and Disability) prospective multinational European study evaluate...
Variants in the inflammatory IL6 and MPO genes modulate stroke susceptibility t...
Vicente, A.M.; Manso, H.; Krug, T.; Sobral, J.; Gaspar, G.; Oliveira, S.; Ferro, J.M.A complex interplay between genetic background, clinical and life-style factors and the environment is expected to ultimately regulate the onset, acute phase and outcome of stroke. There is substantial evidence that inflammation within the Central Nervous System contributes to stroke risk, and known clinical risk factors for stroke, like atherosclerosis, diabetes, obesity, hypertension, and peripheral infection...
A genome-wide association study using a DNA pooling strategy identifies BBS9 an...
Manso, H.; Paulos-Pinheiro, S.; Krug, T.; Sobral, J.; Albergaria, I.; Gaspar, G.; Ferro, J.M.; Oliveira, S.A.; Vicente, A.M.Stroke is a major cause of morbidity in developed countries and therefore finding adequate treatments to promote patient’s recovery is a priority task, requiring the elucidation of the molecular pathways influencing brain recovery. Few studies, however, have assessed the role of genes in stroke outcome. This study describes a pilot genome-wide association study (GWAS) to identify genetic factors contributing to...
Kalirin: a novel genetic risk factor for ischemic stroke
Krug, T; Manso, H; Gouveia, L; Sobral, J; Xavier, J; Albergaria, I; Gaspar, G; Correia, M; Viana-Baptista, M; Simões, R; Pinto, A; Taipa, R; Ferreira, CCerebrovascular and cardiovascular diseases are the leading causes of death and disability worldwide. They are complex disorders resulting from the interplay of genetic and environmental factors, and may share several susceptibility genes. Several recent studies have implicated variants of the Kalirin (KALRN) gene with susceptibility to cardiovascular and metabolic phenotypes, but no studies have yet been perfo...
Mutations of the GLA gene in young patients with stroke: the PORTYSTROKE study-...
Baptista, V; Ferreira, S; Pinho-e-Melo, T; Carvalho, M; Cruz, V; Carmona, C; Silva, F; Tuna, A; Rodrigues, M; Ferreira, C; Pinto, A; Leitão, ABACKGROUND AND PURPOSE: Fabry disease is an X-linked monogenic disorder caused by mutations in the GLA gene. Recent data suggest that stroke in young adults may be associated with Fabry disease. We aimed to ascertain the prevalence of this disorder among young adult patients with stroke in Portugal by GLA genotyping. METHODS: During 1 year, all patients aged 18 to 55 years with first-ever stroke, who were admit...
Association of a genetic variant in the ALOX5AP with higher risk of ischemic st...
Domingues-Montanari, S.; Fernández-Cadenas, I.; Del Rio-Espinola, A.; Corbeto, N.; Krug, T.; Manso, H.; Gouveia, L.; Sobral, J.; Mendioroz, M.Variants in the 5-lipoxygenase-activating protein (ALOX5AP) and phosphodiesterase 4D (PDE4D) genes have first been associated with ischemic stroke (IS) through whole-genome linkage screens. However, association studies obtained conflicting results. We aimed to investigate the contribution of selected single nucleotide polymorphisms (SNPs) in these genes for the first time in a large Iberian population.
Variants of the Matrix Metalloproteinase-2 but not the Matrix Metalloproteinase...
Manso, H.; Krug, T.; Sobral, J.; Albergaria, I.; Gaspar, G.; Ferro, J.M.; Oliveira, S.A.; Vicente, AM.Multiple lines of evidence suggest that genetic factors contribute to stroke recovery. The matrix metalloproteinases -2 (MMP-2) and -9 (MMP-9) are modulators of extracellular matrix components, with important regulatory functions in the Central Nervous System (CNS). Shortly after stroke, MMP-2 and MMP-9 have mainly damaging effects for brain tissue. However, MMPs also have a beneficial activity in angiogenesis ...
