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...

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...

No effect of calcium and vitamin D intake on maternal blood pressure in a healthy pregnant population
Pregnancy causes physiological changes in blood pressure (BP). In patients without pre-existing hypertension, BP falls during the first half of pregnancy and rises from 34 weeks onwards [1]. Hypertensive disorders in pregnancy (HDP) complicate approximately 10% of pregnancies and are associated with adverse outcomes for both mother and foetus [2]. Women with a history of HDP are also at increased risk of developing hypertension in later life as well as ischaemic heart disease, stroke and renal disease [3].

Investigation of the Relationship Between Breath Retention Time and Blood Parameters in Stroke Patients
Conclusion: Partial oxygen and carbon dioxide pressures and blood elements in the blood affect the breath holding time. People with high blood storage capacity and carbon dioxide and oxygen capacity can hold their breath longer. As a result, we think that the higher the hemoglobin and hematocrit levels in the blood, the longer the breath holding time can increase.

In situ metabolite and lipid analysis of GluN2D-/- and wild-type mice after ischemic stroke using MALDI MSI.
Abstract The N-methyl-D-aspartate (NMDA) receptor is a crucial mediator of pathological glutamate-driven excitotoxicity and subsequent neuronal death in acute ischemic stroke. Although the roles of the NMDAR's composite GluN2A-C subunits have been investigated in this phenomenon, the relative importance of the GluN2D subunit has yet to be evaluated. Herein, GluN2D-/- mice were studied in a model of ischemic stroke using MALDI FT-ICR mass spectrometry imaging to investigate the role of the GluN2D subunit of the NMDA receptor in brain ischemia. GluN2D-/- mice underwent middle cerebral artery occlusion (MCAO) and bra...

A New Study Suggests Vegetarians and Vegans Are at Higher Risk of Stroke. But Don ’t Reach for That Steak Just Yet
Vegetarians and vegans are likely to be concerned by the results of a new study with a surprising finding: those following meat-free diets, which are typically associated with better cardiovascular health, may actually have a higher risk of stroke than those who eat meat. But it’s too soon to run out and order a steak. The paper, published in the BMJ, found only a small increase in the risk of stroke, while confirming findings in other studies that vegetarians and vegans may have a lower risk of heart disease than meat-eaters. “It’s important to emphasize that we’ve looked at two outcomes here,R...

What is the current role for vitamin D and the risk of stroke ?
Abstract Increasing evidence support the relationship between vitamin D and stroke. Vitamin D have now been proposed as a prognostic biomarker for also functional outcome in stroke patients. A revision of the data suggests that low vitamin D is associated more with ischemic than with haemorrhagic stroke, even if the role of optimal vitamin D levels for vascular wall is still unclear. Vitamin D deficiency induces with different mechanisms an alteration of vascular wall. However, to date, the research supporting the effectiveness of vitamin D supplementation in stroke and in post-stroke recovery is still inadequate ...

Vitamin D deficiency increases blood-brain barrier dysfunction after ischemic stroke in male rats.
Abstract Because vitamin D hormone deficiency (VDHdef) can worsen severity and outcome for ischemic stroke, we examined the role of VDH in maintaining blood-brain-barrier (BBB integrity) in a rat model of stroke. In most types of stroke, the BBB is markedly compromised, potentially leading to a cascade of injury processes and functional deficits, so we examined a number of biomarkers associated with BBB disruption to determine whether VDH deficiency would further compromise the BBB following a stroke. Male Wistar rats were randomly assigned to one of two diet cohorts, VDH-sufficient (VDHsuf) and VDHdef. The VDHsuf...

Vitamin D 3 Supplementation Reduces Subsequent Brain Injury and Inflammation Associated with Ischemic Stroke
AbstractAcute inflammation can exacerbate brain injury after ischemic stroke. Beyond its well-characterized role in calcium metabolism, it is becoming increasingly appreciated that the active form of vitamin D, 1,25-dihydroxyvitamin D3 (1,25-VitD3), has potent immunomodulatory properties.
