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: Metabolic syndrome is more prevalent in postmenopausal women, who also have a higher prevalence of hypovitaminosis D. Several cross-sectional studies have shown an inverse association between serum 25-hydroxyvitamin D concentrations and MetSyn. However, there is a lack of randomized controlled trials investigating the effect of vitamin D intake on biomarkers and prevalence of MetSyn.

Summary: This study reveals the association between serum 25-hydroxyvitamin D levels and the gut microbiota and metabolites in postmenopausal women. The low 25(OH)D group showed higher diversity in the gut microbiota, while the high 25(OH)D group exhibited specific enrichments of certain bacterial genera. Additionally, the metabolic profiles differed between the two groups.

Summary: The objective of this study was to evaluate vitamin D status and its predictors in Slovenian premenopausal and postmenopausal women. The study found that vitamin D insufficiency and deficiency were common among both premenopausal and postmenopausal women, with vitamin D supplementation and sun exposure being important predictors of vitamin D status. Interestingly, the vitamin D status in Slovenian postmenopausal women was better than in premenopausal women, which differs from similar studies.

Summary: The study found no significant association between 25(OH)D concentration and GDM risk, but individuals with vitamin D deficiency had a higher risk of developing GDM. Additionally, there was a nonlinear relationship between 25(OH)D and GDM risk.

Summary: Metformin reduces FSH levels and tends to decrease LH levels in postmenopausal women, but only in those with normal vitamin D status or receiving vitamin D supplementation. Vitamin D status determines the impact of metformin on gonadotropin secretion. The drug does not affect the levels of other anterior pituitary hormones or vitamin D.

Summary: This study successfully developed a robust and accurate method for simultaneous measurement of serum 25(OH)D, 1,25(OH)(2)D, and 24,25(OH)(2)D by LC-MS/MS with efficient separation of 3-epi analogs, 23R,25(OH)(2)D-3, and 4 beta,25(OH)(2)D-3.

Summary: This study indicates that the majority of pregnant women are deficient in vitamin D during pregnancy, despite the intake of pregnancy vitamins containing vitamin D. Therefore, individualized vitamin D assessment should be considered to ensure adequate supplementation and prevention of hypovitaminosis D.

Summary: Hypercalciuria is a common metabolic disorder that can lead to chronic kidney disease and bone complications. A study is being conducted to investigate the effectiveness of fluconazole, an antifungal drug, in reducing and normalizing calciuria levels in patients with hypercalciuria and increased 1,25(OH)(2)D levels.

Summary: Vitamin D deficiency is a global public health problem, particularly affecting the elderly and individuals with comorbidities. Deficiency weakens the immune system, increasing the risk of infections and complications. This can be remedied through food fortification, supplementation, and sun exposure. Vitamin D plays a crucial role in immune cells, providing protective immune functions. Maintaining adequate serum vitamin D levels is important for a robust immune system.

Summary: This study retrospectively assessed the association between 25(OH) vitamin D levels and long COVID in COVID-19 survivors 6 months after hospitalization. The results showed that COVID-19 survivors with long COVID had lower levels of 25(OH) vitamin D compared to matched patients without long COVID. The findings suggest that evaluating vitamin D levels in COVID-19 patients after hospital discharge is important.

Summary: PTH plays a crucial role in regulating calcium and phosphate balance in adults, with various clinical manifestations and cardiovascular risks associated with parathyroid disorders. While most PHPT patients are asymptomatic, they still face cardiovascular risks; Ps-HypoPT patients show resistance to PTH with unclear CV risks; HypoPT patients often develop hormonal deficiency syndrome post-surgery, leading to increased CV risk.

Summary: Preliminary findings suggest that bone marrow adipocyte secretions may contribute to bone loss by inducing transdifferentiation of osteoblasts into adipocytes. This phenomenon was confirmed in elderly subjects, indicating a potential mechanism for decreased bone mass with aging.

Summary: Patients with chronic hypoparathyroidism managed with conventional therapy, including oral calcium and active vitamin D, may have a higher risk of renal complications such as nephrolithiasis and nephrocalcinosis compared to the general population. Studies show an increased risk of chronic kidney disease in these patients, with rates varying depending on the duration of disease and treatment.

Summary: This clinical practice guideline provides evidence-based recommendations for the prevention, diagnosis, and management of hypoparathyroidism. Evaluating serum PTH within 12 to 24 hours post total thyroidectomy can predict the development of permanent postsurgical hypoparathyroidism. Genetic testing may be helpful for individuals with nonsurgical hypoparathyroidism.
