Hypovitaminosis C Prevalence and Risk Factors in an Acute Geriatric Unit
Vitamin C is essential for numerous biological processes as it acts as a cofactor in various hydroxylation reactions, but also as a powerful antioxidant. As humans have lost the ability to synthetize Vitamin C, this micronutrient is found exclusively in the food, and more particularly in fresh fruits and vegetables. …
Vitamin D3 Supplementation in Critically Ill Patients Undergoing CRRT
Patients hospitalized in intensive care units (ICU) are particularly susceptible to vitamin D3 deficiencies. This can be due to the severity of their underlying disease, the type of treatment they are on, malnutrition before and inadequate nutrition during the hospitalisation preceding ICU admission, as well as advanced age. It has …
Rapid Normalization of Vitamin D Deficiency in PICU
Vitamin D plays an important role in calcium balance, heart and lung health, inflammation, infection prevention, and muscle strength. Due to these roles, it has been suggested that critically ill patients with low vitamin D levels might have higher rates of death and worse long-term health. We believe that identifying …
Effect of Vitamin D Status and Repletion on Postoperative Total Joint Arthroplasty Complications
Vitamin D status has been shown to have an effect on post-operative outcomes in total joint arthroplasty. The goal of this study is to determine if pre-operative supplementation and correction of Vitamin D deficiency can reduce postoperative complications.
Early Infant Micronutrition and Development
Globally, vitamin B12 deficiency is one of the most common micronutrient deficiencies. Poor status is also seen in affluent countries such as in Norway. Vitamin B12 is crucial for normal cell division and differentiation and necessary for the development and myelination of the central nervous system. Deficiency is also associated …
The VITDALIZE Study: Effect of High-dose Vitamin D3 on 28-day Mortality in Adult Critically Ill Patients
In the VITdAL-ICU trial using a large oral dose of vitamin D3 in 480 adult critically ill patients, there was no benefit regarding the primary endpoint hospital length of stay. However, the predefined subgroup with severe vitamin D deficiency (25(OH)D ≤ 12ng/ml) had significantly lower 28-day mortality (36.3% placebo vs. …
Egg Intervention During Pregnancy in Indonesia
The study consists of two arms: 1) intervention group using eggs as supplementary food given from 2nd trimester of pregnancy to birth, and 2) observational group of pregnant mothers. it aims to assess the effectiveness of improving dietary quality during pregnancy on the epigenetic and stunting related outcomes (growth and …
Vitamin D in School Children
The primary purpose of this study it to investigate total circulating 25-hydroxyvitamin D (25(OH)D) in school children (aged 4-11years) in Northern Ireland; thereby establishing the prevalence of vitamin D status (deficiency, insufficiency, and sufficiency (SACN 2016)) in this cohort. Additionally, the study aims to determine if 10µg/day vitamin D3 supplementation …
Effects of Vitamin D Supplementation on Depression and Inflammatory Markers
The current study is designed as a prospective partially randomized patient preference (PRPP) trial and recruit psychiatric outpatients or inpatients. Participants who agree to receive randomization will be randomly assigned into a supplementation or placebo group, after stratification for pre-intervention vitamin D status (12-20 ng/mL or <12 ng/mL) and depression …
Effects of Vitamin D Supplementation in Adolescents With Asthma, Obesity and Vitamin D Deficiency.
Obesity has been associated with a specific non-allergic asthma phenotype and to a deficiency of vitamin D in at least 90% of the pediatric population. Adolescents with non-allergic asthma and vitamin D deficiency have up to six times the risk [OR: 6.2 (IC95% 2.0-21.6), p=0.002] of having a severe asthmatic …
