TL;DR: The goal of this review is to provide an updated review of the literature on the basic science of how vitamin D may affect the cardiovascular system and in particular to analyze the role thatitamin D may have in the whole dynamic process from the initiation of endothelial dysfunction to the development of myocardial infarction and stroke.
Journal ArticleDOI
Vitamin D and walking speed in older adults: Systematic review and meta-analysis
Cédric Annweiler,Cédric Annweiler,Samir Henni,Stéphane Walrand,Manuel Montero-Odasso,Gustavo Duque,Guillaume T. Duval +6 more
TL;DR: A meta-analysis provides robust evidence that 25OHD concentrations are positively associated with walking speed among adults and risk of slow walking speed according to vitamin D status.
Journal ArticleDOI
Hypovitaminosis D and orthostatic hypotension: a systematic review and meta-analysis
Francesca Ometto,Brendon Stubbs,Cédric Annweiler,Guillaume T. Duval,Wooyoung Jang,Hee Tae Kim,Kevin McCarroll,Conal Cunningham,Pinar Soysal,Ahmet Turan Isik,Claudio Luchini,Marco Solmi,Giuseppe Sergi,Enzo Manzato,Nicola Veronese +14 more
TL;DR: It is highlighted that hypovitaminosis D is associated with orthostatic hypotension, independent of potential confounders, and further longitudinal studies and clinical trials are required to confirm these findings.
Journal ArticleDOI
Anatomic Correlation of the Mini-Mental State Examination: A Voxel-Based Morphometric Study in Older Adults
Mickael Dinomais,Sébastien Celle,Guillaume T. Duval,Frédéric Roche,Samir Henni,Robert Bartha,Olivier Beauchet,Cédric Annweiler,Cédric Annweiler +8 more
TL;DR: Worse MMSE and SMMSE scores were associated with gray matter atrophy mainly in the limbic system, highlighting that atrophy of specific brain regions are related to performance on the MMSE-SMMSE tests, and provides new insights into the cognitive function probed by these tests.
Journal ArticleDOI

TL;DR: Evidence is provided that high 25OHD concentrations may be protective against AMD, and that 25O HD concentrations below 50nmol/L are associated with late AMD.
