Filter by:University students are susceptible to psychological burdens such as depressive symptoms, anxiety, and stress which might have been linked to vitamin D deficiency. Low serum vitamin D level is well recognized around the world. Vitamin D has been reported to modulate several neurological pathways in the brain that control psychological function. As a result, the purpose of this study is to evaluate the effect of vitamin D supplementation on the presence of depressive symptoms, anxiety, and stress in university students. The study will include two phases. The first phase is a cross-sectional phase assessing the prevalence vitamin D deficiency in addition to psychological symptoms. The second phase is a randomized controlled clinical trial that aims to assess the effect of vitamin D supplementation on the prevalent psychological symptoms and its impact on the academic performance among university students. The study will look at the relationship between mental health and vitamin D deficiency, as well as how it will affect academic performance of university students.
Vitamin D is important for bone health, immune function, and inflammation, along with dental implant success. The study aimed to assess bone markers and cytokine levels in patients with and without vitamin D insufficiency to better understand the effects of vitamin D levels on dental implant integration. The study included 42 patients in 2 groups; with insufficient (Group IN-S; n=21) and sufficient (Group S; n=21) levels of vitamin D. Bone remodelling, proinflammatory and antiinflammatory markers were analyzed in bone and peri-implant crevicular fluid (PICF) using enzyme-linked immunosorbent assay (ELISA) and results were reported as concentration and total amount.
The aim of this observational retrospective study is to evaluate the effect of supplementation with cholecalciferol D3 in reducing the risk of: - occurence of Long COVID syndrome after acute COVID-19 illness - occurence of SARS-CoV-2 infection after anti-COVID-19 vaccination
The investigators hypothesize that single oral high dose supplementation with vitamin A will reduce the incidence of moderate-severe chronic graft-versus-host disease (GVHD) compared with placebo.
The aims of the study was to correlate the extent of the dimensional alveolar bone changes after tooth extraction and contextual guided bone regeneration with serum vit D levels in 14 patients. Moreover, at 4 months, a small bone sample was collected in order to correlate histological and immunohistochemical parameters of bone with vit D serum levels.
This is a three-arm unblinded prospective interventional study of vitamin D supplementation in participants with insufficient vitamin D at three different induction and maintenance dosing regimens (high dose, low frequency; medium dose, medium frequency, and low dose, high frequency). Measurements of serum vitamin D will take place at 4, 8, 12, 24, and 36 weeks, and will be compared to determine which regimen was most effective at achieving and maintaining ideal serum vitamin D levels.
- This is a single-site retrospective electronic chart review of Cooper Health System Inpatients and Outpatients from 2008 through 2023 aged eighteen years or older. This review is designed as an emulation of a randomized clinical trial with a nonrandomized database. - The primary objectives are to compare healthcare costs and healthcare utilization between subjects who have corrected low vitamin D levels and those without corrected low vitamin D levels.
Lipedema is a disease characterized by bilateral abnormal fat deposition in the upper and lower extremities. Pain is a common symptom in lipedema.Vitamin D plays an important role in chronic pain. Vitamin B have analgesic role in some neuropathic pain conditions.This study aimedto evaluate the relationship between vitamin D and vitamin B12 levels and neuropathic pain in lipedema.
Vitamin D plays an important role in phosphocalcic metabolism and bone homeostasis in newborns. Premature newborns are at risk of vitamin D deficiency and may require supplementation. In this context, the French Society of Pediatrics (Société Française de Pédiatrie) recommends systematic vitamin D testing at 1 month. The aim of this study was to determine the frequency of vitamin D deficiency in premature newborns.
The VitDTracking study focuses on the relevance of maternal vitamin D levels and their association with prematurity, aiming to improve maternal and child health outcomes, particularly by reducing avoidable preterm births. In Portugal, vitamin D levels during pregnancy have never been studied. Epidemiological data from other countries reveal a high prevalence of vitamin D deficiency/insufficiency, especially in pregnant women. The hypovitaminoses prevalence remains high even with a supplementation dosage of 400 to 600 IU/day during pregnancy (dosage used in Portugal), which is considered as a suboptimal dose. This phenomenon is associated with adverse maternal and child outcomes, such as intrauterine growth restriction, preeclampsia, cholestasis, hypertension, and gestational diabetes as major causes of prematurity. Additionally, the Portuguese population has a higher prevalence of genome alterations that confer a lower capacity to produce vitamin D from sunlight exposure. These genetic characteristics are present in about 19% of the population, representing a prevalence four times higher than the European average (19% versus 4.75%), leading to a higher predisposition to vitamin D deficiency.
