Filter by:Objective: The aim of the present study was to determine the effect of nursing interventions and sunlight exposure to reach optimum vitamin D levels by individuals living in nursing homes on vitamin D levels. Material Method: In the first stage of this two-stage randomized-controlled experimental study with pretest-posttest design conducted in June - August 2018 period in the nursing home in Central Town of Tokat Province, the questionnaire prepared by the researcher, standardized mini mental test, Fitzpatrick skin typing questionnaire and Katz Index of activities of daily living were applied. Intervention (n=20) and control (n=20) groups were established with individuals using simple random method according to age, gender, skin type and vitamin D level. In the second stage, 30-35% of the body surface area of individuals in the intervention group was exposed to sunlight five days a week in July. For the participants in the control group, sunbathing was not offered. 25(OH)D, calcium, parathormone, phosphorus, alkaline phosphatase and albumin levels of all individuals were measured in blood samples taken at the beginning and end of the study. Two-way mixed ANOVA, Mann-Whitney U test, Wilcoxon signed rank test and Chi-square tests were used to evaluate the data.
Current study shows that vitamin D deficiency might affect human's immune function. Although breast milk is the best food of infants, however the vitamin D content in breast milk is low. Thus, breastfeeding infants are at high risk of vitamin D deficiency.Children's development and health are always the most important issues for parents. However, high prevalence of allergy in infants in Taiwan were not only with environmental factor which may also relate to their nutritional status. The aim of this study was to enroll breastfeeding infant at age of 4 month, and provide vitamin D supplement 10 μg daily until 6 month, to discuss the effects of vitamin D supplementation on immune function in infants.
To assess if vitamin D status in the elective foot and ankle fusion population affects fusion healing categorically (fused vs. un-fused).
Zinc d vitamin and b12 serum levels in covid-19 positive pregnants will be compared in terms of patients' responses to computed tomography and treatment.
This study will measure vitamin D levels in adults with COVID 19. Participants with low levels of vitamin D will be entered into an open label trial of supplementation with vitamin D.
The investigators aimed to evaluate the relationship between LUTS and vitamin D with uroflowmetry parameters in female patients. They found no relation between vitamin D levels and LUTS in respect to uroflowmetry. However, in low vitamin D patients, Ca is related with urologic problems. The investigators believe that there is a need for studies emphasizing serum Ca levels in addition to vitamin D levels in patients with LUTS.
In this prospective observational study we aim to study the association of vitamin D deficiency with adverse clinical outcomes in patients infected with Coronavirus disease 2019
The 2019 novel coronavirus disease (COVID-2019) pandemic is an enormous health issue of worldwide scale. Prevention and/or treatment with a widely-available and already-licensed product such as vitamin D (cholecalciferol) could have a large impact on healthcare worldwide. Given ethnic variation in vitamin D production, this could help to address the discrepancies in how people of different ethnicities are affected by COVID-19. There are currently no published studies analysing either individual-level evidence on the effect of vitamin D status on COVID-19 outcomes, or any prospective studies planning on following-up patients with reference to vitamin D and COVID-19 infection. The study will have 2 arms. Arm 1 will recruit patients hospitalised with COVID-19. Vitamin D levels will be measured in these patients and compared with outcome measures of COVID-19 severity. In Arm 2, patients will be recruited prospectively from local general practices (GPs) with measurement of vitamin D levels at enrolment. They will be followed up after 6 months to determine whether baseline vitamin D levels correspond with developing COVID-19. Data will be collected from a mixture of patient medical records, electronic patient records, laboratory data and from patients themselves. Data in Arm 1 will be analysed with a combination of linear and logistic regression, as appropriate, and with adjustment for covariates. Data in Arm 2 will be analysed as a case-control study, with adjustment for covariates. The primary objectives are to determine whether vitamin D levels affect outcomes in COVID-19 infection and whether vitamin D deficiency is associated with increased risk.
Aim. To assess the effect of different doses of vitamin D supplementation on peripheral neuropathy in patients with type 2 diabetes mellitus (T2DM). 68 patients with T2DM and peripheral neuropathy will be randomized into two treatment groups: cholecalciferol 5,000 IU once/week and cholecalciferol 40,000 IU once/week orally for 24 weeks. Severity of neuropathy (neuropathy symptom score (NSS), neuropathy disability score (NDS), visual analog scale (VAS)), body mass index (BMI), glycated hemoglobin (HbA1c), 25-hydroxycalciferol (25(OH)D), parathyroid hormone (PTH), serum interleukins (IL) 1β, 6 and 10, C-reactive protein, tumor necrosis factor α and microcirculation (MC) parameters assessed before and after treatment. The initial and final indicators of the skin blood flow (M, σ, Kv) and MC parameters after postural and occlusal tests by laser Doppler flowmetry (LDF). Sixteen subjects without diabetes will represent the control group.
This study assesses whether oral supplementation with vitamin D contributes to the reduction of body mass index and lipid profile in adolescents and young adults. The intervention group will receive 1000 IU of vitamin D (DV) and the control group 200 IU of DV.
