Background: Diet is a major exogenous source of vitamin D. The objective of this analysis was to determine whether the yes/no answer to a simple question exploring diet (Do you eat fatty fish at least once a week and/or eggs several times per week?) ...
Background: Previous studies have shown the relationship between in utero lung development and vitamin D [25(OH)D], but there have been no studies to investigate whether vitamin D deficiency is a risk factor for respiratory distress syndrome (RDS) in ...
Background/Objectives: Severe vitamin D deficiency can be treated with oral loading doses of cholecalciferol. Our objective was to develop an algorithm to accurately calculate the amount of cholecalciferol needed for a loading dose, and what factors ...
Objective: Obesity has been associated with vitamin D deficiency and increased oxidative stress, which can lead to the dysregulation of adipokines and inflammation. The aim of the present work was to examine the association of vitamin D status [25(OH)D] ...
Abstract. Introduction: There is sparse evidence of the effect of vitamin D on bone biomarkers in diabetic patients, and therefore, in a randomized clinical trial, we evaluated the effects of the daily intake of vitamin D, either with or without extra ...
Abstract. Vitamin D deficiency is associated with rickets in children, with osteoporosis in the elderly, is thought to increase the risk of certain cancers and of cardiovascular diseases, and may have an impact on many other health conditions. Asians are ...
There is currently insufficient evidence of a beneficial effect to recommend vitamin D supplementation for optimizing glycemic status in patients with type 2 diabetes mellitus (T2DM). Taking into consideration the ...
Abstract. Scientists and physicians have suggested that poor vitamin D intake can result in increased cardio-vascular mortality. Also total mortality appears to be increased with poor vitamin D status. A research team of the German Cancer Research Center ...
Abstract.The relationship between Hashimoto’s thyroiditis and vitamin D has been demonstrated in several studies. The aim of the present study was to evaluate vitamin D concentrations in patients with Hashimoto’s thyroiditis, the ...
Abstract. The incidence of metabolic syndrome (MetS) has been increasing globally and it is recognized as a major public health problem because MetS is associated with increased risk of diabetes, stroke, cancer, and other chronic diseases. Recently, MetS ...
Abstract. Upper respiratory tract infections are the most common infections reported by elite athletes. Low vitamin D status has been associated with an increased risk of upper respiratory tract infections. The aim ...
