Research Progress on the Correlation Between Vitamin D and Neurological Disorders
Conclusion VD deficiency is very common in the population and is associated with a variety of neurological diseases. VD, a neuroactive steroid, plays an important role in the protection of the central nervous system. In contrast, stroke can cause epilepsy and varying degrees of changes in cognitive function. Furthermore, seizure and epilepsy can cause changes in cognitive function. The degree of alteration in cognitive function affects the occurrence and progression of stroke and epilepsy. Therefore, VD can be used for the comprehensive treatment of neurological diseases.PMID:34936071 | DOI:10.5137/1019-5149.JTN.34816-21.1

Weak UVB Irradiation Promotes Macrophage M2 Polarization and Stabilizes Atherosclerosis
AbstractAtherosclerosis (AS) is a chronic cardiovascular disease endangering human health and is one of the most common causes of myocardial infarction and stroke. Macrophage polarization plays a vital role in regulating plaque stability. As an important component of sunlight, ultraviolet B (UVB) has been proven to promote vitamin D and nitric oxide synthesis. This research used an AS model in ApoE−/− mice to study the effects of UVB on macrophage polarization and atherosclerotic plaque stability. In vitro, UVB irradiation increased arginase-I (Arg-I, M2 macrophage) and macrophage mannose receptor (CD206) expression, w...

The role of rehabilitation and vitamin D supplementation on motor and psychological outcomes in poststroke patients
Post-Stroke depression affects between 12% and 72% of patients who have suffered a stroke. The association between low serum levels of 25-hydroxyvitamin D (25(OH) D) and increased risk of depression is reported in both stroke and non-stroke patients. Similarly, high 25(OH) D levels might be associated with greater functional improvement during rehabilitation program. We wanted to investigate the effects of an intensive rehabilitation on poststroke outcomes. We wondered if the daily rehabilitation of motor and cognitive functions could also have an effect on mood and functional abilities in addition to or as an alternati...

Effect of Vitamin D Supplementation on the Prognosis of Post-stroke Fatigue: A Retrospective Cohort Study
Conclusions: Our results indicated that vitamin D supplementation could improve fatigue symptoms and neurological outcomes in PSF patients with vitamin D deficiency. Subject to replication in other settings, a randomized controlled trial (RCT) might be undertaken to validate the potential beneficial impact of vitamin D supplementation in post-stroke patients found to be vitamin D deficient.

Independent and Combined Effects of Calcium and Vitamin D Supplementation on Blood Lipids in Overweight or Obese Premenopausal Women: A Triple ‑Blind Randomized Controlled Clinical Trial
Conclusions: Although the results were not significantly different among the four treated groups at 8 weeks, within ‑group changes like the reduction in triglyceride and LDL levels, respectively in the Ca group and Ca + Vit D group, and HDL levels in both the Ca and Ca + Vit D groups were significant. These changes may have potentially significant public health implications.

Neurosteroids: a novel promise for the treatment of stroke and post ‐stroke complications
AbstractStroke is the primary reason for death and disability worldwide, with few treatment strategies to date. Neurosteroids, which are natural molecules in the brain, have aroused great interest in the field of stroke. Neurosteroids are a kind of steroid that acts on the nervous system, and are synthesized in the mitochondria of neurons or glial cells using cholesterol or other steroidal precursors. Neurosteroids mainly include estrogen, progesterone (PROG), allopregnanolone, dehydroepiandrosterone (DHEA), and vitamin D (VD). Most of the preclinical studies have confirmed that neurosteroids can decrease the risk of strok...

Low vitamin D levels and the long ‐term functional outcome of stroke up to 5 years
ConclusionVitamin D level less than 38.4  nmol/L at admission is a potential risk biomarker for poor functional outcome at 5-year prognosis in AIS patients, which might provide new ideas for the prognostic assessment of stroke.

Nutritional Supplementation of Naturally Occurring Vitamin D to Improve Hemorrhagic Stroke Outcomes
Vitamin D deficiency, if left untreated, is associated with bone disorders, cardiovascular damage, and an increased risk of ischemic stroke. While there are various nutritional options for the natural intake of vitamin D, we hope to elucidate the potential mechanisms dietary vitamin D may play in hemorrhagic stroke pathology. This scoping review outlines findings from studies relevant to the biochemical activity of vitamin D, the impact of vitamin D deficiency on hemorrhagic stroke outcomes, and the potential benefit of nutritional vitamin D on hemorrhagic stroke outcomes. Here, we analyze the relevant factors that can lea...

Association between Vitamin D and Risk of Stroke: A PRISMA-Compliant Systematic Review and Meta-Analysis
Conclusions: Our analysis indicated that lower circulating level of vitamin D was associated with an elevated risk of stroke, but extra supplement of vitamin D failed to show benefit in decreasing the risk of stroke. Further research and study are also needed to show the role of vitamin D in relation to stroke.Eur Neurol

Parathormone levels add prognostic ability to N ‐terminal pro‐brain natriuretic peptide in stable coronary patients
ConclusionsParathormone is an independent predictor of cardiovascular events in coronary patients, adding complimentary prognostic information to NT ‐proBNP plasma levels. This predictive value is restricted to patients with high FGF23 plasma levels. This should be considered in the design of future studies in this field.

Role of vitamin D in cerebrovascular disease
Conclusions: After reviewing current literature on the subject, we conclude that there are some data to suggest the role of vitamin D in patients with stroke but it cannot be concluded as a risk factor for stroke. Larger population-based studies are needed to confirm the causative role of vitamin D in stroke.
