Filter by:The goal of this observational study is to verify the role of adipose tissue in determining the vitamin D serum level after monthly oral administration in subjects with vitamin D deficiency. The main questions it aims to answer are: - Adipose tissue represents a storage environment for vitamin D or it's an environment where vitamin D is sequestered and no longer released - On the other hands, it's possible to verify whether the adipose tissue carries out a bi-modal activity towards vitamin D - If adipose tissue exerts a bi-modal effect, it is possible to identify a specific threshold between the two effects Participants will undergo anthropometric measurements (height, weight, waist/hip ratio waist circumference) at baseline and after 6 months of intake of cholecalciferol 50,000 IU/month
The purpose of this study is to evaluate the efficacy of supplementation with Omega 3, Vitamin D and Calcium, in a cohort of children with ALL undergoing treatment and compare changes in the concentrations of biomarkers of bone resorption (TRAP5b, CTX, and RANKL), the RANKL/OPG ratio, and biomarkers of bone formation (BALP, OC, PINP, PICP and OPG) after 6 and 12 weeks of supplementation.
There are no clear international guidelines for dosing vitamin D based on deficiency severity. Therefore, a new clinical trial is needed to evaluate the benefits of early vitamin D supplementation in maintaining sufficient levels for critically ill patients. The investigators conducted a multicenter clinical trial in Taiwan focusing on vitamin D and critically ill patients. 240 patients with low calcidiol levels will be enrolled and be provided varying supplementation doses to maintain their serum calcidiol levels ≥ 30 ng/mL within 30 days of ICU admission. The results will serve as a valuable reference for intensivists when formulating appropriate vitamin D treatment strategy to maximize clinical benefits for critically ill patients.
This is prospective single-blind randomized study, in Ain Shams University hospital) in Egypt, to assess the impact of Cholecalciferol on Anemia status in regular hemodialysis outpatients
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.
