Filter by:The goal of this randomized controlled trial is to explore the relationship between Vitamin D supplementation and depressive symptomatology in Saudi Arabian Population. The main questions it aims to answer are: - Is Vitamin D deficiency associated with an increased prevalence of depressive symptomatology among Saudi Arabian Population? - Is Vitamin D Supplementation for a period of 3-month at 50,000 International Units might be associated with an improved depressive status? All the participants were clients who attended the clinic to help with weight management - who were doing regular medical check-ups - at Al Themal Medical Center which is located in Abha, Saudi Arabia. Participants were requested to do a general blood test to check for any vitamins and minerals deficiencies as part of the routine clinical procedure. This procedure did not incur any additional costs on the behalf of the participants. The participants who were identified to have any deficiencies were recommended to take supplements, also as part of the routine clinical procedure. Therefore, participants identified to be deficient or insufficient Vitamin D levels were screened and recruited to participate in the current study. Participants were randomly assigned to either an interventional (vitamin D) or placebo group (control). The interventional group received vitamin D supplementation of 50.000International Units/week for 3 months and the placebo group received dietary advice and education on food sources of vitamin D for the same period. Both Groups received a weight gain or a weight loss diet as per their case. At the three-months follow-up, the participants were readministered the face-to-face questionnaire and their blood levels for vitamin D were also checked. Thus, this study would add value to the actions taken to treat vitamin D deficiency in Saudi Arabian adults. This might also assist in approaching new recommendations related to preventing or treating depression via vitamin D supplementation.
Randomized double blind placebo controlled trial of vitamin D supplements, with or without calcium supplementation, versus placebo in reduction of recurrences in BPPV.
This is a multicenter randomized, placebo-controlled trial of Vitamin D supplementation in patients on peritoneal dialysis to determine whether oral administration of vitamin D3 after curing an episode of peritonitis could reduce the risk of subsequent peritoneal dialysis-related peritonitis.
To evaluate the efficacy of vit D supplement in cancer patients which receive taxane drugs with vit D deficiency and complaining from Peripheral neuropathy
The goal of this prospective cohort study is to learn about the overall and seasonal prevalence of vitamin D insufficiency and its determinants in a population of women with infertility who will go through in vitro fertilization in Sweden. The main questions it aims to answer are: - What is the prevalence of vitamin D insufficiency? - What are the determinants of this insufficiency? Participants will be asked to complete a questionnaire validated for dietary assessment of vitamin D intake and sun exposure habits and they will leave a blood sample for measurement of 25(OH)D concentration. Researchers will compare the in vitro fertilization outcomes between women with vitamin D insufficiency and sufficiency to see if there is any difference.
The objective of this single-center prospective observational study is to clarify the trend of maternal serum 25(OH)D levels before pregnancy and during pregnancy, and to explore the correlation between serum 25(OH)D levels and subsequent pregnancy outcomes of patients with abortion, so as to provide certain scientific evidence for finding the optimal serum level of 25(OH)D and optimal vitamin D supplementation to maintain a healthy pregnancy.
The aim of the study was to assess the effect of high intensity statin therapy on testicular and adrenal steroids and vitamin D levels in type 2 diabetes males.It is a prospective study, conducted between march 2021 and July 2022, including 60 men with type 2 diabetes, aged 40 - 65 years, statin-free, and in whom a treatment with high intensity statin was indicated. The patients had two visits, before and six months after a daily intake of 40 mg of atorvastatin. During each visit, they underwent a clinical examination including the Androgen Deficiency in the Aging Male (ADAM) questionnaire and a fasting blood sample was collected for biological and hormonal measurements.
Vitamin D is essential for skeletal growth and bone health, deficiency causes rickets and osteomalacia. In the UK 29% of adults have vitamin D deficiency. It is recommended all adults take 10µg vitamin D supplement daily. Genetic variations could alter vitamin D status by affecting vitamin D metabolism. Systematic reviews found variations in VDR, GC and CYP2R1 genes are associated with vitamin D deficiency. This study aims to assess the effects between vitamin D supplementation and variations in VDR, GC and CYP2R1 genes on vitamin D status.
A comparison between resistive exercise and high intensity interval trainig on calcium and vitamin d in premenopausal women.
This study aims to understand how vitamin D (VD) affects human health. Typically, prisoners are low on vitamin D, as it is difficult to receive through diet, and is mostly obtained via exposure to the sun. The investigators predict that VD supplements could help improve overall mental well-being, as well as improve bone health. The investigators aim to recruit two groups of participants from a United Kingdom (UK) Prison, all of whom will participate via an informed consent process. The first group of prisoners will have chosen to take VD supplements, the second group will have chosen not to take VD supplements. At the start of the study, prisoners will have their bone density and blood VD levels tested. The investigators will also ask participants to complete a series of questionnaires to understand the state of mental well-being at the start of the study. Participants will be asked to complete a food diary to track dietary intake over the following week. Additionally, the investigators are interested in identifying what proportion of participants have a specific genetic makeup relating to their ability to metabolise VD, and participants will be asked to provide a saliva sample to test this. Every month following the start of the study, participants will be asked to complete the same questionnaires and food diary again. On the 3rd month, the investigators will again test the participants' bone density and blood levels of VD, to see whether supplementation has improved participant VD status. This study will run for a minimum of 3 months, up to a maximum of 6.
