Summary: A study was conducted to assess the effectiveness of monitored vitamin D supplementation in preterm infants. Results showed that a higher percentage of infants in the monitored group had safe vitamin D levels, while potential vitamin D toxicity was observed in the standard treatment group. Therefore, vitamin D intake should be between 800-1000 IU and monitored to avoid overdose.

Summary: This randomized controlled trial aimed to investigate the effects of a one-time dose of vitamin D3 prior to total knee arthroplasty. The results showed no significant improvements in functional scores, walking test times, or complications in the early postoperative period when compared to the placebo group.

Summary: In a study involving newly resected stage II melanoma patients, adjuvant vitamin D3 significantly increased serum 25OHD levels, particularly in patients with a baseline Breslow score under 3 mm. Patients with low 25OHD levels and Breslow score >= 3 mm had shorter disease-free survival, suggesting a potential impact of vitamin D on melanoma prognosis. Larger trials with vitamin D supplementation in melanoma subjects are needed to further investigate these findings.

Summary: This study aimed to assess the effect of vitamin D supplementation during pregnancy on glucose levels and identify factors influencing the response to vitamin D intake. The results showed that vitamin D supplementation significantly protected glucose homeostasis, and the response to vitamin D may be influenced by basal vitamin D levels, VDR gene polymorphism, and metabolic profiles.

Summary: COVID-19 symptoms range from asymptomatic cases to severe illness requiring hospitalization and intensive care. Low vitamin D levels have been associated with increased severity and mortality of COVID-19. However, this study found no significant benefit of vitamin D supplementation in patients with severe COVID-19 disease admitted to the ICU and in need of respiratory support.

Summary: This study found that monthly high-dose vitamin D supplementation did not reduce the risk of falls, and may potentially increase the risk of falling in individuals with normal BMI. Further investigation is needed to better understand the impact of vitamin D supplementation on falls risk in different populations.

Summary: This study aimed to assess the effect of vitamin D supplementation at different doses on serum 25(OH)D concentrations in preschool children. After three months, there was a significant increase in serum concentrations of 25(OH)D and a decrease in the prevalence of vitamin D deficiency. No adverse effects were observed.

Summary: This study aimed to assess whether vitamin D-3 supplementation could attenuate the decline in daily physical activity in low-functioning older adults. The results showed that supplementation with 1000 IU/day or higher of vitamin D-3 did not attenuate the decline in physical activity compared to 200 IU/day. Individuals with baseline serum 25(OH)D levels < 20 ng/mL experienced accelerated declines in physical activity.

Summary: Maternal supplementation of 20 μg vitamin D-3/d is more effective in achieving target 25(OH)D concentrations in pregnancy compared to 10 μg, especially for obese women. Low maternal 25(OH)D concentrations at baseline may lead to deficiencies in umbilical cord 25(OH)D, highlighting the importance of adequate vitamin D supplementation during pregnancy, especially for obese women.

Summary: This post hoc analysis investigated the effects of vitamin D on blood pressure and found that vitamin D supplementation did not have an antihypertensive effect in individuals with vitamin D deficiency. However, there was a significant association between achieved 25(OH)D concentrations and blood pressure.

Summary: This meta-analysis investigated the effects of vitamin D supplementation on in vitro fertilization (IVF) outcomes in infertile women with vitamin D deficiency. The results showed that vitamin D supplementation was associated with improved chemical pregnancy rate, but did not benefit clinical pregnancy rate and other secondary outcomes. Further studies are needed to confirm these findings.

Summary: This study is the first to assess the effect of vitamin D supplementation on microvascular reactivity in obese adolescents, finding that vitamin D supplementation can improve vascular function, attenuate microvascular dysfunction, without altering macrovascular function.

Summary: This study investigated the effect of daily vitamin D supplementation on leg power and physical performance in older adults with low 25(OH)D concentrations. The results showed that 2000 IU/d vitamin D3 did not improve leg power, physical performance, or muscle fiber composition.

Summary: The study found a significant increase in the incidence of myopericarditis in men after COVID-19 vaccination, while there was no significant change in women. However, the rate of myocardial injury was significantly higher in 2021, which may contribute to the increased diagnosis of myopericarditis after vaccination.
