BACKGROUND Dietary vitamin D supplementation is associated with reduced risk of type 1 diabetes in animals. Our aim was to ascertain whether or not vitamin D supplementation or deficiency in infancy could affect development of type 1 diabetes. METHODS A birth-cohort study was done, in which all pregnant women (n=12055) in Oulu and Lapland, northern Finland, who were due to give birth in 1966 ...

Canadian First Nations (FN) population experiences a high burden of tuberculosis. Vitamin D is known to enhance the expression of innate immune effectors, including cathelicidin LL-37, for protection against infections. In this study we performed longitudinal analyses to investigate the impact of vitamin D supplementation on macrophage responses to Mycobacterium tuberculosis (Mtb) lipoprotein (...

BACKGROUND Ireland is at 53°N, and its population risk of vitamin D deficiency is high. Previous Irish studies suggested a significant seasonality of serum 25-hydroxyvitamin D [25(OH)D] and a beneficial effect of supplementation in raising 25(OH)D levels. However, in Irish older people, little is known about the magnitude of the supplementation effect and whether supplementation affects 25(OH)D...

abstract background: premenstrual syndrome (pms) can cause problems in daily work and relationships. materials and methods: eighty‑six women were randomly assigned to two intervention groups and one control group. patients were asked to fill out the pms daily symptoms record for 2 months, and then the participants were randomly assigned to one of the three study groups. medical intervention was...

background: pregnancy is associated with unfavorable metabolic profile, which might in turn result in adverse pregnancy outcomes. the current study was designed to evaluate the effects of calcium plus vitamin d administration on metabolic status and pregnancy outcomes in healthy pregnant women. methods: this randomized double‑blind placebo‑controlled clinical trial was performed among 42 pregna...

Infants fortunate enough to be exclusively breastfeeding are at risk for insufficient vitamin D intake, and if vitamin D deficient, are at risk for rickets. Despite an unequivocal recommendation by the American Academy of Pediatrics to provide 400 IU of oral vitamin D daily beginning in the first days postpartum, national studies conducted both before and after publication of these recommendati...

UNLABELLED Beta-alanine supplementation has been shown to improve exercise performance in short-term high-intensity efforts. However, whether supplementation with beta-alanine is ergogenic to actual sporting events remains unclear and should be investigated in field testing or race simulations. PURPOSE The aim of this study was to assess if beta-alanine supplementation could improve 2,000-m r...

The objectives of this research were to determine the influence of protein supplementation frequency on cow performance, grazing time, distance traveled, maximum distance from water, cow distribution, DMI, DM digestibility, harvest efficiency, percentage of supplementation events frequented, and CV for supplement intake for cows grazing low-quality forage. One hundred twenty pregnant (60 +/- 45...

The objective of this experiment was to determine if frequency of protein supplementation impacts physiological responses associated with reproduction in beef cows. Fourteen nonpregnant, nonlactating beef cows were ranked by age and BW and allocated to 3 groups. Groups were assigned to a 3 × 3 Latin square design, containing 3 periods of 21 d and the following treatments: 1) soybean meal supple...

There is increasing concern that vitamin D deficiency poses a major health problem for children. Deficiency can cause hypocalcemic seizures, growth disturbances, and rickets and may influence diabetes, cardiovascular dysfunction, autoimmune diseases, and attention deficit hyperactivity disorders. Reduced vitamin D levels in children presenting to pediatric orthopedic services are common.In the ...
