Journal ArticleDOI
Vitamin D and Delirium in Older Adults: A Case-Control Study in Geriatric Acute Care Unit.
Justine Chouet,Guillaume Sacco,Spyridon N. Karras,David J. Llewellyn,Dolores Sánchez-Rodríguez,Cédric Annweiler,Cédric Annweiler +6 more
TL;DR: Lower serum 25OHD concentrations were associated with delirium among acute geriatric inpatients and the threshold concentration to differentiate between cases and controls was around 30 nmol/L.
Journal ArticleDOI
Association between CUBN gene variants, type 2 diabetes and vitamin D concentrations in an elderly Greek population.

Karras,Marianthi Georgitsi,Marianthi Georgitsi,Nikolaos Papanas,Dimitrios Papazoglou,Athanasios Roumeliotis,Stylianos Panagoutsos,Elias Thodis,Marios Theodoridis,Ploumis Pasadakis,E. Maltezos,Peristera Paschou,Kalliopi Kotsa +15 more
TL;DR: The results indicate a potential role of CUBN gene in T2DM genetic susceptibility in the Greek population and may also denote an indirect effect of vitamin D metabolism dysregulation on the pathogenesis of T2 DM.
A rare case of a parathyroid adenoma inside a parathyroid cyst Um caso raro de adenoma de paratireoide em um cisto de paratireoide
Spyridon N. Karras,Ioannis Koutelidakis,Panagiotis Anagnostis,Gesthimani Mintziori,Nikolaos Pontikides,Dimitrios G. Goulis +5 more
TL;DR: In this article, the authors report a case of functional parathyroid cysts (PCs) and describe its diagnostic and therapeutic approach, which can be found in the neck and anterior mediastinal region.
Journal ArticleDOI
Vitamin D receptor Fokl polymorphism is a determinant of both maternal and neonatal vitamin D concentrations at birth.
Spyridon N. Karras,Theocharis Koufakis,Vasiliki Antonopoulou,Dimitrios G. Goulis,Merve Alaylıoğlu,Erdinç Dursun,Duygu Gezen-Ak,Cédric Annweiler,Stefan Pilz,Hana Fakhoury,Fatme Al Anouti,Vikentia Harizopoulou,Declan P. Naughton,Pantelis Zebekakis,Kalliopi Kotsa +14 more
TL;DR: Results suggest a protective role of maternal Fokl FF genotype against both maternal and neonatal vitamin D deficiency, and are needed to clarify the complex gene-gene and gene-environment interactions that determine vitamin D status at birth.
Journal ArticleDOI
Should the last be first? Questions and dilemmas regarding early short-term insulin treatment in Type 2 Diabetes Mellitus.
TL;DR: Early short-term insulin treatment (STIT), defined as insulin administration shortly after diabetes diagnosis for only a brief period of time, is an alternative concept, aiming to entirely revise the perspective of type 2 diabetes (T2DM) management.
