Summary: This study aimed to investigate the necessity of monitoring 1,25-dihydroxyvitamin D levels in hemodialysis patients. The results showed that there was a significant increase in 25-hydroxyvitamin D levels in patients treated with native vitamin D, but no significant change in 1,25-dihydroxyvitamin D levels. For patients treated with active vitamin D, there were no significant changes in both 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D levels. Therefore, monitoring 1,25-dihydroxyvitamin D levels in patients newly treated with active vitamin D does not seem useful.

Summary: This study found that serum hepcidin-25 levels were associated with ferritin and TSAT, and could serve as an independent predictor for all-cause mortality in MHD patients. Patients in the high-level hepcidin-25 group had lower survival rates, with a hazard ratio of 1.225 for all-cause mortality per 10ng/mL increase in hepcidin-25.

Summary: This study explored the relationship between serum 25(OH)D, cadmium, and CRP with all-cause mortality among people with and without diabetes. The results showed that serum 25(OH)D deficiency was associated with higher all-cause mortality and cardiovascular mortality in diabetic patients, while high cadmium and high CRP levels were associated with higher all-cause mortality and cancer mortality. Similar results were found in non-diabetic patients, but with varying levels of risk.

Summary: This study investigated the joint association of serum 25-hydroxyvitamin D [25(OH)D] and klotho with mortality risk in American community-dwelling adults. The results showed that vitamin D-associated mortality risk is observed only with concurrently decreasing klotho, indicating that vitamin D metabolism dysfunction increases the risk of mortality.

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: 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: 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 found a significant negative correlation between serum vitamin D levels and all-cause and cardiovascular disease mortality among adults with diabetes, suggesting that maintaining adequate vitamin D levels may help reduce mortality risk.

Summary: This longitudinal cohort study examined the relationship between serum levels of 25-hydroxyvitamin D [25(OH)D], parathyroid hormone (PTH), beta-C-terminal telopeptide of type 1 collagen (beta-CTX), and all-cause mortality in centenarians. Lower 25(OH)D levels, higher PTH levels, and higher beta-CTX levels were associated with increased mortality in Chinese community-dwelling centenarians. The association with 25(OH)D was linear, while the associations with PTH and beta-CTX were J-shaped.

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: 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: This study aimed to assess the association between vitamin D (VD) and mortality in patients with osteoarthritis (OA). The results showed an L-shaped association between serum 25(OH)D concentrations and all-cause mortality, and an inverse association with cardiovascular disease (CVD) mortality. Patients with sufficient 25(OH)D concentrations had a lower risk of all-cause and CVD mortality compared to those with insufficient or deficient levels.
