Nutrition is considered to be a possible factor in the pathogenesis of the neurological disease multiple sclerosis (MS). Nutrition intervention studies suggest that diet may be considered as a complementary treatment to control the progression of the disease; a systematic review of the literature on the influence of diet on MS was therefore conducted. The literature search was conducted by using Medlars Online International Literature (MEDLINE) via PubMed and Scopus. Forty-seven articles met the inclusion criteria...

BACKGROUND: Evidence of a role for vitamin D (VitD) in cognitive aging is mixed and based primarily on extreme VitD deficiency. We evaluated the association of VitD insufficiency with cognitive function in older, community-dwelling adults living in a temperate climate with year-round sunshine. METHODS: A population-based longitudinal study of 1,058 adults (median age 75; 62% women) who had cognitive function assessed and serum levels of 25-hydroxyvitaminD (25OHD) measured in 1997-99 and were followed for up to three additional cognitive function assessments over a 12-year period...

CONTEXT: Lower urinary tract symptoms (LUTSs) in elderly males are usually related to benign prostatic hyperplasia (BPH) in the majority of cases. It is estimated that BPH affects half of men above the age of 50 years. Recently, a relationship between Vitamin D deficiency and LUTS in elderly males has been reported. AIMS: The aim of this study was to analyze Vitamin D levels in males aged above 50 years presenting with LUTS. SETTINGS AND DESIGN: This is a prospective case-control study...

BACKGROUND/INTRODUCTION: Recent studies have indicated a much broader role to Vitamin D than simply the regulation of calcium metabolism alone. Vitamin D likely confers physiologically relevant pleiotropic functions that include cardioprotective and immunomodulatory effect, and its deficiency could lead to increased risk of cardiovascular disease and heart failure. AIM: The aim of our work was to evaluate the presence of hypovitaminosis D in patients with dilated cardiomyopathy (DCMP) and to study any correlation of echocardiographic parameters with Vitamin D deficiency...

BACKGROUND: The role of vitamin D deficiency and inflammation levels in renal anemia has been documented. However, no study is available in India where the role of vitamin D supplementation in patients with hyporesponsiveness to increased doses of erythropoietin is available. Hence this study. MATERIAL AND METHODS: This study was conducted on 50 adult patients of CKD, on regular, twice weekly hemodialysis. It included 38 cases in group A with deficient serum vitamin D levels (<30 ng/ml) and 12 cases in group B with sufficient vitamin D levels (>30 ng/ml)...

Humans obtain vitamin D from conversion of 7-dehydrocholesterol in the skin by ultraviolet B (UVB) radiation or from dietary sources. As the radiation level is insufficient in winter, vitamin D deficiency is common at higher latitudes. We assessed whether vernal solar UVB radiation at latitudes 61°N and 67°N in Finland has an impact on serum 25-hydroxyvitamin D [S-25(OH)D] concentrations. Twenty-seven healthy volunteers participated in outdoor activities in snow-covered terrain for 4-10 days in March or April, with their face and hands sun-exposed...

Vitamin B12 (B12) adequacy during pregnancy is crucial for maternal health and optimal fetal development; however, suboptimal B12 status has been reported in pregnant Canadian women. Methylmalonic acid (MMA) is a sensitive indicator of B12 status. Since few studies have measured MMA during pregnancy in Canadian women, the objective of this study was to evaluate B12 status in pregnant women living in Metro Vancouver, using both plasma total B12 and MMA. We recruited a convenience sample of 320 pregnant women between 20 and 35 gestational weeks from local healthcare facilities...

The follow-up of celiac disease (CD) is challenging due to the scarcity of published data and the lack of standardized evidence-based protocols. The worldwide frequency and methods of CD follow-up appear to be heavily influenced by expert opinions of the individual physicians who assess children with CD. The aim of this review was to summarize the available studies on CD follow-up in children. We conducted a literature search with the use of PubMed, Medline, and Embase (from 1900 to 15 December 2016) for terms relevant to this review, including CD, follow-up, dietary adherence or dietary compliance, nutrition, comorbidities, complications, and quality of life...

BACKGROUND: Iodine is an essential nutrient required for the biosynthesis of thyroid hormones, which are responsible for regulating growth, development and metabolism. Iodine requirements increase substantially during pregnancy and breastfeeding. If requirements are not met during these periods, the production of thyroid hormones may decrease and be inadequate for maternal, fetal and infant needs. The provision of iodine supplements may help meet the increased iodine needs during pregnancy and the postpartum period and prevent or correct iodine deficiency and its consequences...

Increased carotid intima media thickness indicates subclinical atherosclerosis. We evaluated the relation between vitamin D level and intima media thickness in patients with type 1 DM. 93 patients (female/male: 48/45, aged 31.5 ± 11.9 years, A1c 9.48 ± 2.43, vitamin D [15.9 (12.1-19.2)]) with type 1 DM were included into the study. Common carotid artery IMT was measured by real time B mode ultrasonography (MyLab 70 XVG, Esaote SpA, Genoa, Italy). Vitamin D was measured using radioimmunassay. Male and female patients (n = 14, 15%) had similar rates of plaque presence (p = 0...
