Summary: There is a strong positive linear correlation between free 25(OH)D (f25(OH)D) and total 25(OH)D, making them useful for assessing vitamin D levels. The recommended threshold level for f25(OH)D is 8.499 pg/mL, corresponding to a target concentration of at least 30 ng/mL for t25(OH)D. The upper limit for vitamin D is still unclear, with most experts favoring a upper limit of 100 ng/mL for t25(OH)D.

Summary: This study found a quasi J-shaped relationship between serum circulating 25-hydroxyvitamin D (25(OH)D) level and risk of recurrent stroke in patients with a stroke history. The lowest risk of recurrent stroke was observed at a 25(OH)D level of approximately 60 nmol/L, which was associated with a 48% reduction in risk compared to a level of 10 nmol/L.

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: In this study, a sensor based on a silver-silver oxide nanoparticles-decorated carbon nanotube-modified glassy carbon electrode was developed for antibody-free, nanomolar detection of 25-hydroxyvitamin D. The sensor showed high sensitivity and a low detection limit, making it suitable for detecting vitamin D deficiency.

Summary: The purpose of this study was to investigate the intake and sources of vitamin D, as well as the determinants of serum 25-hydroxyvitamin D (S-25(OH)D) in Finnish adolescents. The results showed that most adolescents had vitamin D intake at the recommended level, although a quarter did not meet the recommended intake and almost a third had low levels of S-25(OH)D. The main determinants of S-25(OH)D were vitamin D intake from supplements, consumption of milk products, consumption of meat products, travels to sunny countries, and average daylight time.

Summary: The study found that the low vitamin D status in recent lactating mothers may have decreased the concentrations of vitamin D and 25OHD in breast milk, compared to the 1980s. This has important implications for improving the vitamin D status of lactating mothers and infants.

Summary: This study using Mendelian randomization found that genetically increased serum 25-hydroxyvitamin D levels were associated with a higher risk of Behcet's disease, with data from Chinese and Turkish cohorts supporting this conclusion. The contribution to Behcet's disease risk may increase with higher levels of vitamin D.

Summary: This study compared the effects of two combined oral contraceptive formulations on 25(OH)D levels and VDBP levels, revealing different impacts. LNG may have a suppressive effect on VDBP. Further research is needed to understand the influence of hormonal contraceptive formulations on vitamin D status and women's health.

Summary: There is an association between specific single nucleotide polymorphisms (SNPs) in genes related to vitamin D metabolism pathway and cord blood 25(OH)D in both mothers and offspring, indicating a potential role of genetic factors in this relationship.

Summary: Shift nurses in Taiwan often experience 25(OH)D deficiency, sleep disturbances, depression, and fatigue. However, no significant correlation was found between 25(OH)D levels and mental health.

Summary: This study found a correlation between 25-hydroxyvitamin D deficiency and tic disorders (TD) in Chinese children, but no correlation between 25-hydroxyvitamin D deficiency and the severity of TD. Additionally, the deficiency of 25-hydroxyvitamin D was most pronounced in children over the age of 9.

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 examined the impact of maternal socioeconomic status (SES) on newborn vitamin D levels. The results showed that newborns born in the summer had significantly higher vitamin D levels compared to those born in the winter. The study also found that living environment had a significant influence on newborn vitamin D levels.

Summary: This study assessed the relationship between assumed risk factors for maternal vitamin D deficiency and levels of cord blood 25(OH)D-3 and C-3-epimer. The results showed that vitamin D deficiency was common in newborns, especially those born to mothers who did not receive vitamin D supplementation and had poor sun exposure.

Summary: Using data from the National Health and Nutrition Examination Survey (NHANES), the study found a reverse J-shaped association between circulating 25(OH)D and stroke history, with the lowest stroke prevalence observed at 60 nmol/L. The prevalence of stroke increased below and above the middle quintile of 25(OH)D (53.2-65.4 nmol/L). More high-quality evidence is needed to establish the causal relationship between vitamin D and stroke risk and the impact of vitamin D supplements on stroke prevention.

Summary: The study evaluated the efficacy of dietary strategies to slow growth in late finishing pigs and their effects on carcass composition and pork quality. The results showed that several dietary strategies can slow finishing pig growth without behavioral vices, but changes to carcass composition and quality were also observed. Quality should be considered when choosing diets to slow growth.

Summary: The tenderness of fresh pork is closely related to postmortem proteolysis. This study used liquid chromatography and mass spectrometry to evaluate the differences in myofibrillar sub-proteome between pork chops with different tenderness values. The results showed that different tenderness values were associated with distinct myofibrillar sub-proteomes.

Summary: The fractionation and proteomic analysis of the aged sarcoplasmic proteome provide insights into the biochemical and proteolytic events related to pork water-holding capacity. The variation in pork quality, including water-holding capacity, poses challenges for pork processors and customers. Identifying the factors influencing water-holding capacity is crucial for improving pork quality prediction methods.
