Summary: Primary hyperparathyroidism and malignancy account for 90% of cases of hypercalcemia, with uncommon conditions needing to be considered when these are not the etiology. Recent research has led to a better understanding of unusual causes of hypercalcemia, emphasizing the importance of focusing on mechanisms and reviewing prior case reports for successful determination of the etiology. Continued investigation into the complexities of human calcium metabolism is crucial due to an increasing number of reports on rare and unknown mechanisms of hypercalcemia.

Summary: Paraneoplastic hypercalcemia is a common but often undiagnosed complication in patients with neuroendocrine neoplasms (NEN). The overproduction and secretion of PTHrP is a major cause of this condition, and a multidisciplinary approach is required for effective management.

Summary: This study investigated the protective effect and potential mechanism of vitamin D on podocyte injury in diabetic kidney disease (DKD). The results showed that treatment with a vitamin D analogue significantly reduced albuminuria and improved renal pathology in diabetic mice. Furthermore, vitamin D enhanced podocyte autophagy activity, restored the expression of slit diaphragm proteins, and inhibited podocyte apoptosis under diabetic conditions.

Summary: The study found an inverse association between serum vitamin D levels and new-onset chronic kidney disease in participants with diabetes. However, this association was not observed in participants without diabetes.

Summary: The prognostic value of vitamin D receptor (VDR) in various digestive system tumors is still controversial. This meta-analysis found that high VDR expression is generally associated with better overall survival (OS) in digestive system tumors, but the association is not significant in colorectal cancer. VDR expression can serve as a prognostic indicator and a reference for vitamin D supplementation, helping to evaluate prognosis and formulate precise treatment plans for patients with digestive system tumors.

Summary: Maternal vitamin D insufficiency during pregnancy may increase the risk of preeclampsia, and lower vitamin D levels at 32 weeks are associated with a higher risk of placenta-mediated complications. Maintaining adequate levels of vitamin D in pregnant women can help prevent the onset of late PMC.

Summary: This study found an association between the CYP24A1 rs2762943 polymorphism and increased risk of multiple sclerosis (MS). Carriers of this risk allele had lower levels of active vitamin D and higher levels of inflammatory factors. However, this genetic variant had no significant impact on disease activity and disability outcomes of MS patients, only with a younger age at disease onset.

Summary: This study investigated the power and sample size requirements in vitamin D supplementation randomized controlled trials (RCTs) and found that the increase in 25OHD in the intervention arm and population heterogeneity substantially impact the power of the trials. Sample size determination through simulation was shown to be a powerful approach for non-standard trials and can be easily applied to other intervention-outcome pairs.

Summary: This study conducted a systematic review and meta-analysis to explore the influence of vitamin D on ankylosing spondylitis (AS). The results showed that patients with AS had lower levels of peripheral 25-hydroxyvitamin D (25OHD) and higher levels of peripheral C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR). This suggests that vitamin D may have a protective effect on AS, and CRP and ESR serve as important biomarkers for AS.

Summary: This study aimed to reveal that VDR gene polymorphisms may constitute a risk factor for necrotizing enterocolitis (NEC). The study found that the TT genotype of VDR Fok1 C/T increased the risk of NEC, and there was a significant relationship between this genotype and the risk of NEC.

Summary: This study aimed to investigate the ability of 1,25(OH)(2)D to predict PTH increase and WRF in CKD stage 3-4. The results showed that lower levels of 1,25(OH)(2)D independently predicted the absolute increase in PTH, while higher levels of 1,25(OH)(2)D were associated with a reduced risk of WRF. The 1,25(OH)(2)D/PTH (1-84) ratio may serve as a composite biomarker of tubular reserve/endocrine response in CKD-MBD.

Summary: The study found that hyperinsulinemia, higher total cholesterol, and LDL cholesterol were associated with increased CIMT among obese adolescent boys. In contrast, there was no association between vitamin D levels and CIMT, and none of the metabolic risk factors were associated with CIMT in girls.

Summary: This study assessed the effects of 1,25(OH)(2)D deficiency and supplementation on alveolar bone loss and gingival inflammation induced by ligature-induced periodontitis. The results showed that 1,25(OH)(2)D deficiency enhanced the severity of alveolar bone loss and gingival inflammation, while supplementation with 1,25(OH)(2)D-3 alleviated these symptoms, although not completely.
