Selenium and cognitive impairment: A brief‐review based on results from the EVA study
Authors: Berr Claudine , Arnaud Josiane , Akbaraly Tasnime N. 
Published: March 2012

AbstractPreventing cognitive impairment and dementia in the elderly is a major public health challenge for our century and all hypotheses should be explored. Selenium (Se) is one of the factors that may affect the risk of cognitive decline. Its importance in the health and aging process has been documented. Because of the potential of selenoproteins to protect against oxidative stress, Se raises significant expectations for the prevention of chronic diseases including cancer, cardiovascular disease, and type 2 diabetes conditions commonly associated with oxidative stress. Thus, the relationships between Se and cognitive impairment or dementia can be examined through vascular risk factors for dementia, with particular interest in diabetes and dyslipidemia. In addition, in cases of Se deficiency, the brain is the organ that remains Se replete the longest suggesting that Se plays an important role in brain functions. This article presents results obtained in the frame of a longitudinal study on Se and cognitive impairment. They are consistent with the hypothesis that low Se status is a risk factor for cognitive decline even after taking into account vascular risk factors. The concomitant evolution between plasma Se decrease over a 9‐year period and cognitive decline suggested that optimal Se status is potentially important to maintain neuropsychological functions in aging people. However, as our understanding of Se biology is incomplete, epidemiological studies are needed to define the groups of population that could benefit from Se supplementation.

AbstractObjectivesThis study was conducted to identify patient‐related variables that are associated with a higher rate of neurological adverse events during carotid artery stenting (CAS).BackgroundCAS is considered as an alternative treatment for patients with carotid artery stenosis. Despite technical advancements and increase of operator experience, periprocedural neurologic complications cannot completely be prevented. Case selection based on anatomical criteria and other patient characteristics could improve the outcome after CAS.MethodsBetween 2006 and 2009, 833 CAS procedures were performed in 751 consecutive patients under cerebral protection. The influence of patient characteristics, procedural details, and the anatomy of the supraaortic vessels on the incidence of major in‐hospital adverse events was assessed.ResultsSuccessful CAS was performed in 99.2% of the procedures. The in‐hospital death and stroke rate was 2.0% (1 major stroke, 10 minor strokes, and 7 deaths). Octogenarians had a fourfold higher death and stroke rate than patients younger than 80 years old. There was an increased risk of stroke and death in patients with critical aortic stenosis. Presence of a bovine arch, tortous common carotid artery (CCA) and angulated distal internal carotid artery were associated with a higher risk of stroke and transient ischemic attack. A recently developed scoring system for anatomic suitability correlates well with the periprocedural neurological outcome in this case series.ConclusionsAnatomical conditions and octogenarian age were associated with an increased rate of neurologic adverse events during CAS. Our findings support a newly proposed scoring system for anatomic suitability to identify patients at high risk for CAS. © 2012 Wiley Periodicals Inc.

Published: March 2012

ObjectivesThe aim of this study was to characterize coronary plaque in target lesions with vessel remodeling using iMap‐intravascular ultrasound (IVUS).BackgroundThe relationship between the plaque component and vessel remodeling remains to be elucidated. iMAP‐IVUS is an imaging system that can be used to assess the plaque composition by radiofrequency signals from 40 MHz IVUS.MethodsIVUS examinations were performed for the de novo target vessels of 146 stable angina pectoris patients (174 vessels). The patients were divided into two groups: including a nonpositive remodeling group (non‐PR, remodeling index ≤ 1.0, 125 vessels) and a positive remodeling group (PR, remodeling index > 1.0, 49 vessels).ResultsThe percent plaque burden in the PR group were lager than those in the non‐PR group (79.05% vs. 74.36%, P < 0.01). Attenuation plaques were more frequently observed in PR group (40.8% vs. 12.1%, P < 0.0001). The percentages of lipidic and necrotic relative areas at the minimum lumen sites were greater in the PR group than in the non‐PR group (7.22% vs. 6.03%, P <0.05 and 22.08% vs. 14.71%, P < 0.001, respectively), and the percentage of the fibrotic area was smaller (54.82% vs. 61.42%, P < 0.05). In addition, a positive linear correlation was observed between the remodeling index and either the lipidic or necrotic area (r = 0.37, P <0.0001 and r = 0.35, P < 0.0001, respectively).ConclusionsThe coronary plaque characteristics in PR patients showed increased lipidic and necrotic areas and the degree of coronary remodeling correlated with the lipidic and necrotic plaque area. © 2012 Wiley Periodicals, Inc.
