PURPOSE: Serum 25-hydroxy vitamin D [25(OH)D] varies greatly with season at northern latitudes. The purpose of this study was to determine if the seasonal variations in serum total 25(OH)D is followed by a concomitant variation in free 25(OH)D or if the variation is damped by alterations in the binding capacity of DBP. METHODS: Serum was collected from 540 healthy blood donors (60% men; mean age 41±13 years) during 12 months and analyzed for total 25(OH)D, directly measured free 25(OH)D, vitamin D binding protein (DBP) and albumin...

BACKGROUND: Excess levels of serum acylcarnitines, which are intermediate products in metabolism, have been observed in metabolic diseases such as type 2 diabetes mellitus. However, it is not known whether acylcarnitines may prospectively predict risk of cardiovascular death or acute myocardial infarction in patients with stable angina pectoris. METHODS AND RESULTS: This study included 4164 patients (median age, 62 years; 72% men). Baseline serum acetyl-, octanoyl-, palmitoyl-, propionyl-, and (iso)valerylcarnitine were measured using liquid chromatography/tandem mass spectrometry...

AIMS: Vitamin K antagonists (VKAs) are used for stroke prevention in patients with non-valvular atrial fibrillation (NVAF) but necessitate regular monitoring of prothrombin time via international normalized ratio (INR) testing. This study explores the economic burden of VKA therapy for Russian patients with NVAF. METHOD: Cardiologists provided clinical characteristics and healthcare resource use data relating to the patient's first year of treatment. Data were used to quantify direct medical costs (INR testing, consultations, drug costs)...

Vitamin D measurements in biological fluids by mass spectrometry are challenging at very low concentration levels. As a result, chemical derivatization is often employed to enhance the ionization properties of low abundant vitamin D compounds. Cookson-type reagents such as 4-phenyl-1,2,4-triazoline-3,5-dione (PTAD) or similar derivatives work well but require careful, water-free experimental conditions, as traces of water inactivate the reagent and inhibit or stop the derivatization reactions, thus making quantitative measurements in aqueous samples impossible...

The aim of this study was to determine the typical incidence of micronuclei (MNi) in the peripheral blood lymphocytes of healthy middle-aged Koreans using the cytokinesis-block micronucleus cytome (CBMN-Cyt) assay. Non-smoking, low-risk alcohol-drinking healthy Korean men and women aged 30 to 59 years were recruited. Participants were divided into three groups according to age, i.e., 30 to 39, 40 to 49, and 50 to 59 years. Fifty participants were included in each age group, for a total of 300 participants. DNA damage was measured based on the number of binucleated (BN) cells with MNi, nucleoplasmic bridges (NPBs), and nuclear buds (NBUDs) using the CBMN-Cyt assay...

Many children in low- and middle-income countries may have inadequate intake of vitamin B12 and folate; data confirming these inadequacies are limited. We used biochemical, demographic, behavioral and anthropometric data to describe the folate and vitamin B12 concentrations among six- to 23-month-old Nepalese children. Vitamin B12 (serum B12 < 150 pmol/L) and folate deficiencies (red blood cell (RBC) folate < 226.5 nmol/L) were assessed. We used logistic regression to identify predictors of vitamin B12 deficiency...

Fruit and yogurt have been identified individually as indicators of healthy dietary patterns. Fruits are relatively low in energy density and are an excellent source of antioxidants and prebiotic fibers and polyphenols, which can promote digestive health. Yogurt, on the other hand, is a nutrient-dense food that is a good source of dairy protein, calcium, magnesium, vitamin B-12, conjugated linoleic acid, and other key fatty acids. In addition, it contains beneficial bacterial cultures, making it a potential source of probiotics...

Hypovitaminosis D is increasingly reported in autoimmune diseases. We investigated the 25-OH-vitamin D (25-OH-vitD) levels in systemic sclerosis (SSc) patients, in correlation with disease's features. We measured the 25-OH-vitD serum levels in 140 consecutive patients (F/M 126/15; mean age 61 ± 15.1 years), 91 without (group A) and 49 with (group B) 25-OH-cholecalciferol supplementation. Patients of group A invariably showed low 25-OH-vitD levels (9.8 ± 4.1 ng/ml vs. 26 ± 8.1 ng/ml of group B); in particular, 88/91 (97%) patients showed vitamin D deficiency (<20 ng/ml), with very low vitamin D levels (<10 ng/ml) in 40 (44%) subjects...
