Summary: This study aimed to investigate the association between bisphenol A (BPA), 25-hydroxy vitamin D [25(OH)D], and 1 alpha,25 dihydroxy vitamin D [1,25( OH)(2)D] levels in cord blood of newborn babies. The results showed that both BPA exposure and insufficient vitamin D transfer via cord blood are common in newborns, but there is no correlation between BPA levels and vitamin D levels in cord blood.

Summary: The study assessed total and bioavailable 25(OH)D levels in postmenopausal women and found associations with bone density and muscle mass, indicating the potential superiority of bioavailable 25(OH)D in reflecting Vitamin D status.

Summary: Vitamin D deficiency is prevalent among young Korean women. This study aimed to determine the optimal vitamin D intake level for maintaining adequate serum 25-hydroxyvitamin D (25[OH]D) levels in young Korean women throughout different seasons. The study identified seasonal factors influencing 25(OH)D levels, calculated the necessary vitamin D intake for sufficient levels, and analyzed the relationship between 25(OH)D and intact parathyroid hormone (iPTH) levels. The results showed that 25(OH)D levels were higher in summertime compared to wintertime, and an increase in vitamin D intake led to a corresponding increase in 25(OH)D levels. The study suggests that increasing UV irradiation time in summertime and consuming vitamin D supplements and foods throughout the year is beneficial for maintaining sufficient levels of 25(OH)D in young Korean women.

Summary: This study established new routes for the chemical synthesis of vitamin D-3 and its hydroxy metabolites. The compounds showed similar properties in inhibiting cell proliferation and inducing cell differentiation, as well as effects on T-cell immune activity. They also interacted with nuclear receptors in a similar manner. The findings have important implications for studying the role of these compounds in the immune system and inflammatory diseases.

Summary: Vitamin D insufficiency or deficiency is common in patients with cardiovascular disease (CVD). Increasing levels of serum 25(OH)D are independently associated with a decreased risk of all-cause and cause-specific mortality among individuals with existing CVD, particularly beneficial for those with vitamin D deficiency.

Summary: Vitamin D is crucial for bone mineralization in children and deficiency is common. Certain medical conditions and genetic alterations can increase the risk of vitamin D deficiency rickets. Measurement of calcifediol levels is used to assess the status of the vitamin D endocrine system. Clinical trials have demonstrated the benefits of ensuring normal 25(OH)D levels and calcium intake in preventing or treating nutritional rickets in children.

Summary: The study found that higher genetically predicted lifelong circulating 25(OH)D levels are associated with higher calcium levels and KSD risk. The effects of 25(OH)D on KSD were partially attenuated but still significant in MVMR.

Summary: This study aimed to investigate the association between serum 25(OH)D levels and the risk of all-cause mortality in patients with prior cardiovascular disease. The results showed that higher serum 25(OH)D levels were associated with a lower risk of all-cause mortality, but the relationship followed an L-shaped pattern. The findings suggest that increasing serum 25(OH)D levels may not provide further reduction in the risk of all-cause mortality.

Summary: This study aimed to evaluate the association between dietary vitamin D intake and serum vitamin D concentrations with cognitive performance in older Americans. The results showed a positive association between dietary vitamin D intake, serum total 25-hydroxyvitamin D, and cognitive performance, with no significant gender differences in the associations. Further research is needed to clarify the effects of dietary vitamin D intake and specific serum D concentrations on cognitive performance.

Summary: Maintaining optimal vitamin D levels after breast cancer treatment is important for reducing recurrence risk and extending survival time. A study in Polish women after mastectomy found that vitamin D deficiency was more common in this group compared to the general population, highlighting the importance of vitamin D supplementation and monitoring. By providing recommendations and increasing awareness about vitamin D supplementation, there was a significant increase in the number of patients who started supplementing and the average dose of supplements.

Summary: This study investigated the association of pro-inflammatory diets with cardiovascular risk (CVR) among pregnant women and whether such association was modified by vitamin D status. The results showed that higher dietary inflammatory potential was associated with increased CVR during pregnancy, but adequate vitamin D could exert anti-inflammatory effects and modify this association.

Summary: This study investigated the impact of whey protein and vitamin D supplementation on muscle mass and quality in post-stroke convalescent rehabilitation patients. The results showed that supplementation with whey protein and vitamin D reduced fat infiltration into the muscles. However, there were no significant differences in muscle strength and daily life activity between the groups. Long-term follow-up studies are needed to confirm the substantial benefits of this nutritional intervention for stroke survivors.

Summary: The study investigated the combination relationship between age, serum 25-hydroxyvitamin D (25(OH) D), and 1,25-(OH)2D3 levels on muscle strength. Results showed that serum 25(OH)D and 1,25(OH)(2) D were not related to muscle strength, but age and the combination of age with these two types of vitamin D significantly improved muscle strength up to middle age.
