Summary: Elevated serum calcium, 25-hydroxyvitamin D, and parathyroid hormone levels were found to be associated with an increased risk of aneurysmal subarachnoid hemorrhage (SAH) in this Mendelian randomization study. The study used genetic variants to predict these hormone levels and found that higher genetically predicted S-Ca and S-PTH levels were associated with an increased risk of aneurysmal SAH. However, there was no association between genetically predicted S-25OHD concentration and aneurysmal SAH.

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: Vitamin D metabolism is altered in obese individuals, and surgery-induced weight loss can increase the threshold of vitamin D and suppress the secretion of parathyroid hormone.

Summary: This study investigated the relationship between 25(OH)D and 1,25(OH)2D with PTH. The results showed a negative correlation between all forms of PTH and 25(OH)D, while there was no significant correlation between 1,25(OH)2D and PTH. This finding suggests an inhibitory effect of 25(OH)D on the synthesis of all forms of PTH in the chief cells of the parathyroid gland.

Summary: This study examined the relationship between serum 25-hydroxyvitamin D and all-cause, cause-specific mortality in patients with RA. It found a nonlinear, L-shaped association, with lower serum 25-hydroxyvitamin D levels being associated with increased risk of all-cause mortality.

Summary: This study indicated an inverse causal relationship between serum PTH concentrations and development of OA, especially knee OA, but no evidence of the causal effect of serum 25(OH)D levels on OA was found. Further investigation is needed to explore potential mechanisms by which serum PTH affects OA.

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: The study found that free and bioavailable 25(OH)D correlated well with total 25(OH)D, but only had a threshold effect on P1NP. A total 25(OH)D of < 15.14 ng/mL was marginally associated with a higher risk of reduced HDL-C. Higher levels of free and bioavailable 25(OH)D were associated with a lower risk of reduced HDL-C. PTH and BTMs responded more sensitively to changes in total 25(OH)D than to free or bioavailable 25(OH)D after vitamin D supplementation in Chinese women of childbearing age.

Summary: Nonlinear associations between serum 25(OH)D levels and all-cause and cardiovascular disease (CVD) mortality were observed in American patients with osteoarthritis (OA). The thresholds of 27.70 and 54.40 nmol/L for CVD and all-cause mortality, respectively, may represent intervention targets for lowering the risk of premature death and cardiovascular disease.

Summary: This study confirms an inverse dose-dependent association between serum 25-hydroxyvitamin D levels and elevated intraocular pressure (EIOP) in a large sample of 15,338 individuals. Each unit increase in serum 25-hydroxyvitamin D is associated with a 3% decrease in the odds of having EIOP. Compared to individuals deficient in 25-hydroxyvitamin D, those with insufficiency and sufficiency have a 28% and 49% lower odds of EIOP, respectively. Therefore, clinical assessment of intraocular pressure may be helpful in the treatment and prevention of glaucoma in patients with insufficient 25-hydroxyvitamin D.

Summary: This study aims to explore the relationship between serum 25-Hydroxyvitamin D (25(OH)D) and all-cause and cause-specific mortality among postmenopausal women. The findings suggest that low serum 25(OH)D levels are associated with higher risk of all-cause and cardiovascular disease mortality in postmenopausal females.

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: Pregnancy leads to increased synthesis of vitamin D binding protein (DBP) and higher concentrations of total vitamin D and metabolites. The ratio of free 25-hydroxyvitamin D (25(OH)D) to parathyroid hormone (PTH) appears to be a better predictor of pregnancy complications, such as gestational diabetes, compared to total 25(OH)D/PTH. Further research is needed to validate and explore this association.

Summary: This study examined how the severity of radiographic knee osteoarthritis (KOA) affects recurrent falls in middle-aged and older individuals. The results showed that older adults with radiographic evidence of KOA had a higher likelihood of experiencing recurrent falls compared to those without KOA, regardless of established risk factors. On the other hand, middle-aged adults with KOA did not have an increased odds of recurrent falls, except for those with possible KOA.

Summary: This study evaluated the risks of clinical fracture, hip fracture, and mortality prior to fracture among men aged at least 80 years. The results showed that fall history, hip bone mineral density, and recent fracture were strong predictors of clinical fracture and hip fracture. Age and multimorbidity were strong predictors of mortality before fracture. The study results have important implications for guiding osteoporosis drug treatment decisions.

Summary: This study assessed the associations between serum concentrations of cytokines and systemic immune biomarkers with the risk of prostate cancer. The results showed that the anti-inflammatory cytokine IL-10 was associated with a lower risk of prostate cancer. Further research on the relationship between IL-10, inflammation, and prostate cancer development is warranted.

Summary: This study followed 135,743 postmenopausal women for 17.7 years and found that postmenopausal women with pelvic cancer, especially those who received pelvic radiation, have a higher risk of pelvic fracture and overall mortality. This suggests that prevention of pelvic fractures should be emphasized in pelvic cancer survivors, in addition to cancer treatment.

Summary: Osteogenesis imperfecta (OI) is a genetic disorder that causes increased bone fragility. Medications used for fracture reduction in adults with OI, such as bisphosphonates and teriparatide, have shown potential in improving bone mineral density (BMD) but lack conclusive data on fracture protection. Other drugs and treatments have not been systematically studied in adults with OI. Further research is needed to develop medications that can effectively reduce fracture rates in adults with OI.

Cox proportional hazards models were used with prospective data from the Osteoporotic Fractures in Men study. The results showed an interaction between D3Cr muscle mass and distal tibia total volumetric BMD (Tt.BMD) in the occurrence of fractures in older men. Importance rating: 7/10.

Summary: A study found that self-reported sleep disturbances were associated with an increased risk of fractures across the menopausal transition. However, after adjusting for confounding factors, this association was largely attenuated, suggesting that shared risk factors or other factors in the causal pathway may contribute to the observed relationship.

The results showed that higher VMR was associated with higher vBMD and bone strength, while 25(OH)D3 had no impact on these outcomes.
