To obtain up-to-date data on nutritional status of older adults, a national dietary survey will be conducted in 2022/2023, providing data on the consumption of foods and enabling the assessment intakes of energy and specific nutrients. Participating subjects will be also screened for micronutrient status using blood biomarkers (focusing into vitamin D, folic acid, vitamin B12, and iron).
This study will be an assessor-blind, randomized controlled trial in patients with CSU. The investigators will compared Vit D level in patients with Chronic spontaneous urticaria (CSU) and controls. Enrolled CSU patients with Vit D level <30ng/ml will be then randomized into three intervention arms in the ratio of 1:1:1. Patients belonging to intervention group A will be treated with low dose Vit D (2000 IU/day) for 12 weeks according to the Indian council of medical research (ICMR) guidelines. Intervention group B patients will be treated with high dose Vit D (60,000 IU/week) for 12 weeks and group C will not be given any Vit D supplements. All patients will be evaluated after 12 weeks. The urticaria activity score over 4 days (UAS4) will be used to assess the disease severity using the number of wheals and pruritus intensity based on the EAACI/GA2LEN/EDF guidelines. The patient's disease severity levels will be graded as mild (0-8), moderate (9-16), and severe (17-24).
Inflammatory bowel disease (IBD), comprising crohn's disease (CD) and ulcerative colitis (UC), is a a chronic, relapsing-remitting systemic disease. Vitamin D is a secosteroid hormone that possesses immunomodulatory properties and has been demonstrated to potentially influence inflammatory bowel disease (IBD) pathogenesis and activity.
To investigate the optimal initial and maintenance doses of vitamin D2 supplementation for the treatment of vitamin D insufficiency in Thai adults, and to determine the prevalence of and risk factors for hypovitaminosis D among Thai adults.
Thus, the aim of the current study is to assess the influence of vitamin D deficiency and, consequently, of serum calcium deficiency in the body composition, muscular activity, bone mineral density, fatigue, and exercise tolerance of CD patients. Secondly, it also aims to determine the impact of vitamin D supplementation on this population.
This study aims to compare the acute effect of consuming milk and butter fortified with either vitamin D3 or 25 (OH) D3 on serum/plasma vitamin D status in humans. In addition, the effect of vitamin D3 or 25 (OH) D3 in milk and butter on certain CVD risk markers and cognitive function will be examined.
Multi-center, prospective, randomized, controlled study to verify the clinical effectiveness of K / DOQI guidelines. The efficiency and safety of Vitamin D2 and low protein diet treatment for prevention and treatment of CKD-MBD and malnutrition in CKD3-5 (ND) patients.
