Summary: This study aims to analyze the associations between serum 25(OH)D levels and the risk of metabolic syndrome (MetS) and its components in non-diabetic women of childbearing age in China, considering both genetic and non-genetic factors. The findings suggest significant associations between insufficient serum 25(OH)D and components of MetS, including elevated waist circumference, triglycerides, and reduced high-density lipoprotein cholesterol. However, no independent associations were found between 25(OH)D levels and MetS, hypertension, and hyperglycemia.

Summary: This study used a meta-meta-analysis method to examine the effects of Vitamin D intake and serum 25-hydroxyvitamin-D levels on cancer incidence and mortality. The findings showed that higher Vitamin D intake and serum levels were associated with lower cancer risk and mortality. However, careful evaluation according to cancer types is important and recommended.

Summary: The study investigated the serum vitamin D levels in vitiligo patients and compared the association of VDR gene polymorphisms in vitiligo patients and healthy controls. The results showed that there were no significant differences in serum vitamin D levels between vitiligo patients and the Korean population, as well as in the genotypic distributions of VDR gene between vitiligo patients and healthy controls.

Summary: The study found that patients with celiac disease have lower Vitamin D levels compared to controls, which improve after treatment, but there is no difference in Vitamin D Receptor genotypes between the two groups.

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: A meta-analysis was conducted to investigate the impact of oral vitamin D supplementation on serum 25-hydroxyvitamin D levels in healthy adults in Europe. The findings suggest that vitamin D supplementation can significantly increase serum 25(OH)D levels, with the effect influenced by dosage and baseline serum levels.

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: This study investigated the association between BPA, 25(OH)D, and 1,25(OH)(2)D levels in cord blood of newborn babies. The study found that both BPA exposure and insufficient vitamin D transfer via cord blood are common in newborns, but BPA levels were not correlated with vitamin D levels in cord blood.

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 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: Our meta-analysis indicates that VDR BsmI and TaqI polymorphisms are associated with OA susceptibility in the spine and the FokI polymorphism is associated with knee OA susceptibility. However, the ApaI polymorphism is not a significant genetic risk factor for OA. Ethnic stratification also showed no significant association between VDR gene polymorphisms and OA in Caucasians or Asians.

Summary: This study conducted a systematic review and meta-analysis to summarize the epidemiological evidence on the associations of vitamin D-binding protein (VDBP), albumin-bound, bioavailable, and free 25(OH)D with mortality. The study found that the highest levels of bioavailable and free 25(OH)D were associated with a decrease in all-cause mortality, similar to the associations observed for total 25(OH)D. Higher VDBP levels were associated with lower all-cause mortality in cancer patient cohorts, but no such association was observed in general population cohorts.

Summary: The meta-analysis suggests that pediatric cases with fractures have lower serum 25(OH)Vit-D levels, and levels less than 50 nmol/L are associated with increased fracture risk in children.
