Vitamin D supplementation in the first 2 years and autism spectrum traits at 6–8 years – a randomized clinical trial

Journal of Child Psychology and Psychiatry, EarlyView.
Background Early life vitamin D levels may be associated with autism spectrum disorder (ASD) and related traits, but causality is unknown. We examine whether higher‐than‐standard vitamin D3 supplementation during the first 2 years, as well as higher pregnancy and childhood 25‐hydroxyvitamin D (25(OH)D) levels and their trajectories, are associated with

Effect of Two Therapeutic Renal Diets on Hormonal and Regulatory Pathways Affecting Calcium Homeostasis in Cats With Early‐Stage Chronic Kidney Disease

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Chronic kidney disease (CKD) is a known risk factor for hypercalcemia in cats. Phosphate‐restricted diets have also been implicated in causing hypercalcemia, in part because phosphate restriction increases the Ca:P ratio. The primary objective of this study was to evaluate the impact of two different therapeutic renal foods on ionized (iCa ...
