Accuracy of 6 Routine 25-Hydroxyvitamin D Assays: Influence of Vitamin D Binding Protein Concentration
TL;DR: Twenty-hydroxyvitamin D measurements performed with most immunoassays suffer from inaccuracies that are DBP concentration dependent, so careful consideration of the measurement method is necessary when interpreting results of 25(OH)D measurements.
Journal ArticleDOI
The association between low vitamin D and depressive disorders
Yuri Milaneschi,Witte J.G. Hoogendijk,Paul Lips,Annemieke C. Heijboer,Robert A. Schoevers,A.M. van Hemert,Aartjan T.F. Beekman,Johannes H. Smit,Brenda W.J.H. Penninx,Brenda W.J.H. Penninx +9 more
TL;DR: Low levels of 25(OH)D were associated to the presence and severity of depressive disorder suggesting that hypovitaminosis D may represent an underlying biological vulnerability for depression.
Journal ArticleDOI
Vitamin D assays and the definition of hypovitaminosis D: results from the First International Conference on Controversies in Vitamin D
Christopher T. Sempos,Annemieke C. Heijboer,Daniel D. Bikle,Jens Bollerslev,Jens Bollerslev,Roger Bouillon,Patsy M. Brannon,Hector F. DeLuca,Glenville Jones,Craig F Munns,John P. Bilezikian,Andrea Giustina,Neil Binkley +12 more
TL;DR: In an effort to bridge knowledge gaps in defining hypovitaminosis D, an international study on rickets as a multifactorial disease is proposed and standardizing 25(OH)D measurement in research is recommended.
Journal ArticleDOI
Effects of Dietary Phosphate and Calcium Intake on Fibroblast Growth Factor-23
Marc G. Vervloet,Frans J. van Ittersum,Rahel M. Büttler,Annemieke C. Heijboer,Marinus A. Blankenstein,Piet M. ter Wee +5 more
TL;DR: Variation in dietary phosphate and calcium intake induces changes in FGF23 (on top of a circadian rhythm) and 1,25D blood levels as well as in urinary phosphate excretion, detectable the day after the change in the phosphate content of meals.
Journal ArticleDOI
Bone mass in young adulthood following gonadotropin-releasing hormone analog treatment and cross-sex hormone treatment in adolescents with gender dysphoria.
TL;DR: Between the start of GnRHa and age 22 years the lumbar areal BMD z score in transwomen decreased significantly and in transmen there was a trend for decrease, suggesting that the BMD was below their pretreatment potential and either attainment of peak bone mass has been delayed or Peak bone mass itself is attenuated.
