Abstract:

Since vitamin D deficiency is common at birth, the objective of this study was to test if postnatal vitamin D supplementation would normalize bone mineralization. Forty guinea pigs were randomized to receive a diet with or without vitamin D3 during pregnancy. Newborn pups were randomized to receive 10 IU of vitamin D3 or a placebo daily until d28. Measurements at birth and d28 included whole body and regional bone mass, osteocalcin and deoxypyridinoline, plus biomechanical testing of excised tibias and femurs. Offspring from deficient sows had lower body weight, whole body and tibia bone miner

Abstract:

Background: Previous research suggests that vitamin D deficiency during pregnancy may be associated with suboptimal fetal growth, but direct evidence is lacking. Our objectives were 1) to develop a method for measurement of the fetal sphenoidal fontanelle area (FA) and femur volume (FV) using 3D ultrasound; 2) to create normal charts for FA and FV; and 3) to correlate FA and FV with maternal vitamin D concentration. Methods: FA measurement in 3D was evaluated in vitro and in vivo. Different segmentation methods for FV measurement were explored. A novel FV method was described which consists of

Abstract:

BACKGROUND: Adequate vitamin D during pregnancy and lactation is important for optimal health of mother and infant. Due to low levels of vitamin D occurring in breast milk, exclusively breastfed infants are recommended by Health Canada to be supplemented with 400 IU/day of vitamin D. A potential solution to this is maternal vitamin D supplementation during pregnancy and lactation to raise maternal, infant serum 25-hydroxyvitamin D (25OHD) and breast milk vitamin D content. OBJECTIVE: To determine the effect of three dose regimens of supplemental vitamin D (400 IU/d, 1000 IU/d and 2000 IU/d) d

Abstract:

BACKGROUND: Attaining adequate vitamin D throughout pregnancy is important for maternal and infant health. Current Canadian guidelines for vitamin D intake vary; the Recommended Dietary Allowance (RDA) set by Health Canada is 600IU/d whereas the Canadian Pediatric Society recommends 2000IU/d. At present, there is a lack of evidence as to the most appropriate intake. OBJECTIVE: To determine the effect of each of three dosages of supplemental vitamin D (400, 1000 and 2000IU) throughout pregnancy on the percentage of women achieving sufficient serum 25-hydroxyvitamin D (25OHD) defined as > 50 nm

Abstract:

Indigenous Panamanian women are burdened by infection which may worsen vitamin A and D status, while deficiencies of these immunomodulating vitamins will further enhance infection burdens. Together, both vitamin deficiencies and infection may impact fetal and infant growth. The main objective of this cross-sectional study was to determine the impact of maternal Vitamins A and D status and infection burden on fetal and infant growth. The secondary objective was to assess the prevalence of vitamin A and D deficiencies in these women and identify maternal, environmental and infection-related fact

Abstract:

Low vitamin D status, defined by circulating 25-hydroxy vitamin D (25(OH)D) <50 or <75 nmol/L is prevalent among pregnant women and has been associated with neonatal rickets and gestational diabetes mellitus (GDM). Osteocalcin (OC), a bone formation biomarker, linking the bone to glucose metabolism is stimulated by 1,25-dihydroxyvitamin D (1,25(OH)2D), the active form of vitamin D. In the first study, maternal serum 25(OH)D and OC were explored at early and mid-gestation in GDM (case, n=48) vs healthy (control, n=48) Caucasian pregnant women. Maternal serum 25(OH)D was not different (p=0.80) w

Vitamin D deficiency is of particular concern among women in many south Asian countries due to low availability of vitamin D-rich foods, dark skin pigmentation, and cultural and religious practices that promote the wearing of concealing clothing. However, information regarding the vitamin D status of many subpopulations in south Asian countries is limited. The current study was conducted to assess the vitamin D status of 147 Bangladeshi women of reproductive age and determine whether vitamin D status influences susceptibility to arsenic-associated skin lesions (75 cases, 72 controls).

In general, increasing vitamin D₃ concentrations or adding 25(OH)D₃ to the maternal diet increases the vitamin D₃ status of the dam and often the progeny as well. Varying results have been reported on the practical and valuable impacts of this elevated status with some topics including improved sow performance, changes in muscle fiber morphometrics, and growth performance to market.

Dyslipidemia is increasing among U.S. children, and the prevalence is highest among children with diabetes and obesity. Recently, vitamin D deficiency has been suggested as a possible dietary risk factor for dyslipidemia. Despite the high prevalence of vitamin D deficiency amongst children, virtually no studies have evaluated the association between vitamin D and dyslipidemia among children. We evaluated the vitamin D and dyslipidemia relationship among 240 children and adolescents aged 2 through 21 years who were outpatients of a pediatric endocrinology unit at a large tertiary care facility
