Associations of Plasma 25-Hydroxy Vitamin D and Dietary Vitamin D Intake with Insulin Resistance in Healthy Japanese Women
J Nutr Sci Vitaminol (Tokyo). 2023;69(1):46-52. doi: 10.3177/jnsv.69.46.ABSTRACTWe investigated the associations of plasma 25-hydroxy vitamin D (25(OH)D) concentration and the dietary intake of vitamin D with insulin resistance in Japanese women. Study participants were 406 Japanese women attended a health examination. They were not taking hormones or medications for diabetes and had no history of cancer, ischemic heart disease, or stroke. Information regarding medical history and lifestyle factors was obtained by a self-administered questionnaire, while hours of sun exposure were determined through interviews. Dietary int...

Vitamin D intake and all-cause and cause-specific mortality in Japanese men and women: the Japan Public Health Center-based prospective study
Eur J Epidemiol. 2023 Jan 31. doi: 10.1007/s10654-023-00968-8. Online ahead of print.ABSTRACTWhile higher circulating 25-hydroxyvitamin D concentrations have been reported to be associated with decreased risk of all-cause mortality, evidence on dietary vitamin D intake is limited and inconsistent. We investigated whether vitamin D intake is associated with all-cause and cause-specific mortality among Japanese adults. Participants were 42,992 men and 50,693 women who responded to the second survey of the Japan Public Health Center-based Prospective Study (1995-1998) and who were followed up for mortality through 2018. Dieta...

Serum 25-hydroxyvitamin D is associated with stroke history in a reverse J-shape
ConclusionUsing data from a large, cross-sectional cohort program, we found that circulating 25(OH)D was related to stroke history in a reverse J-shaped manner. Given how the causal relationship between circulating 25(OH)D and history of stroke has not been established, more high-quality evidence based on the reverse J-shaped feature is needed to elucidate the link between vitamin D and stroke risk, and the effect of vitamin D supplements on stroke prevention.

An Evidence-Based Review of Vitamin D for Common and High-Mortality Conditions
Conclusion: Prospective studies of vitamin D supplementation demonstrate variable impact on disease specific and patient-oriented outcomes, suggesting a correlation but not a causal relationship between low vitamin D levels and disease pathogenicity. Future research should determine dosing standards and timing of vitamin D in treatment and prevention.

Correlation between Vitamin D, homocysteine and brain-derived neurotrophic factor levels in patients with ischemic stroke
CONCLUSIONS: Vitamin D supplementation was used as a therapeutic agent in patients with acute ischemic stroke that affects homocysteine and BDNF levels. In this study, it was demonstrated for the first time that there is a correlation between serum vitamin D levels and BDNF levels in patients who have experienced a stroke.PMID:36394751 | DOI:10.26355/eurrev_202211_30154
