Filter by:This study is a cohort study that aims to assess the relationship between Vitamin D Levels in infant and the risk of anemia, atopic dermatitis, diarrhea and cardiovascular disorders in newborn. The subjects of this study are 100 women who met the inclusion criteria, which are in their third trimester of pregnancy and agree to be included in this study. These subjects then will be examined for their weight using standardized CEBA digital scale, height, upper arm circumference, and blood sampling will also be done to these women to measure their vitamin D levels, calcium, parathyroid hormone, ferritin, Fe serum, IL-16, IL-10. When subjects give birth, the babies will also be included in this study. Anthropometric examination will also be done on the babies, to measure their birth weight, birth length, and head circumference. Blood samples will also be taken from their umbilical cord to assess their complete blood count, ferritin, Fe serum, vitamin D levels, vitamin D receptors, IL-6 and IL-10. All subjects then will be monitored, and home visits will be done when the babies reach 3 months old and 6 months old. An assessment of the incidence of diarrhea, atopic dermatitis, and an assessment of cardiovascular disorders (checking pulse and blood pressure) will be carried out during the visit. At the end of the study, venous blood sampling will be taken to see levels of vitamin D, calcium, parathyroid hormone, routine complete blood count, serum Fe, and ferritin, then data analysis is performed.
Cystic fibrosis (CF) is an autosomal recessive disease caused by alterations in the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene, characterized by multisystemic alterations, mainly in the lung, intestine, sweat, and bile ducts. In addition to pulmonary involvement, the presence of exocrine pancreatic insufficiency also increases the risk of survival, as it is associated with malnutrition and deficiency of fat-soluble vitamins, such as vitamin D. Vitamin D, in addition to its role in bone health, in the case of CF patients with chronic inflammation, it has been suggested that many of the cytokines that regulate the inflammatory response contain elements that respond to vitamin D, so vitamin D could play an essential role in the regulation of the inflammatory response in CF, which could favor lung function. However, more than 50% of CF patients present vitamin D insufficiency or deficiency, despite the different schemes suggested for supplementation in different age groups, which suggests that new strategies are needed to normalize vitamin D levels, which will allow us to see its clinical effect on the inflammatory response, by decreasing the number of exacerbations and thus perpetuating or improving lung function, as well as on bone mineral health.
To study the effect of vitamin D supplementation on disease activity of SLE ( SLEDAI-2K ) and IL-6 level
The hypocalcemia after total thyroidectomy is one of common surgical complications. It may be asymptomatic, but patients can complain of dysfunction around the mouth or extremities, stiffness or convulsion in severe cases. The incidence of transient hypocalcemia was 6.9-46%, and permanent hypocalcemia was reported to be 0.4-33%. It has been reported that the incidence of hypocalcemia after thyroidectomy is high when the difference in blood levels of parathyroid hormone and vitamin D is large before and after surgery. Therefore, it is a very important task to study the effect of using vitamin D3 (cholecalciferol), which has a better effect on the human body, on the prevention of hypocalcemia after total thyroidectomy with a long follow-up period after surgery. The department of surgery in Seoul National University Hospital intends to analyze the preventive effect "D-mac 30,000 IU" on postoperative hypocalcemia and safety of 'D-mac 30,000 IU" through a prospective randomized clinical trial. The incidence of postoperative hypocalcemia of the group taking orally taking vitamin D3 (cholecalciferol) before surgery will be compared with that of the group not taking vitamin D3 before surgery. Patients who are enrolled in this RCT are allocated to the case group and the control group. Patients in the case group are taking 30,000 IU of vitamin D3 (cholecalciferol) orally, and patients in the control group are not taking any drugs. Primary endpoint of this study is to evaluate the incidence of hypocalcemia. And secondary endpoints are to evaluate the recovery duration from postoperative hypocalcemia and the risk factors for postoperative hypocalcemia.
This retrospective prospective study is aimed at studying the level of vitamin D supply and identifying markers of bone tissue remodeling in order to develop approaches to the prevention of osteopenia and osteoporosis in children with congenital epidermolysis bullosa.
Many studies have pointed out that patients with vitamin D deficiency have a longer stay in the intensive care unit and a poor prognosis. The investigators' previous multi-center prospective observational study in Taiwan reveals that the prevalence of vitamin D deficiency in critically ill patients in northern Taiwan is 59%, and the prevalence of severe vitamin D deficiency is 18%. The investigators used the data of that observational study to train a predictive model for predicting vitamin D deficiency. In addition, the association between vitamin D and the immune regulation of critically ill patients in Taiwan has not been investigated. This study aims primarily to validate the performance of the prediction model of vitamin D deficiency. Moreover, this study will investigate the association between vitamin D level and inflammatory cytokine levels. This multi-center prospective observational study will enroll critically ill patients admitted to intensive care units (ICUs) less than 28 days. After inform consent, blood will be drawn for examination of vitamin D, interleukin 6, and interleukin 10 levels. The main diagnosis of ICU admission, past medical history, vital signs within 24 hours of admission, disease severity, and laboratory data will be recorded. The predictive model will use the required parameters to predict the patient's risk of vitamin D deficiency and vitamin D severe deficiency.
This is a single site double blind randomized controlled trial of replacing Vitamin D for Vitamin D-deficient burn patients at a current recommended dose (400 IU daily) versus a higher dose (4000 IU daily). Capsules will be made in a compounding pharmacy and will look identical. Randomized controlled trial. People who meet the selection criteria will be randomized to either low or high dosage of Vitamin D. Treatment arm is high dose Vitamin D (4000 IU), and control is low dose Vitamin D (400 IU). Main outcome variables include PROMIS-29 measures of physical health, mental health and social health, the Veterans RAND 12 Item Health Survey (VR-12), and the 4-D Itch Scale. Secondary outcome variables include subject demographics, injury demographics and characteristics.
Connective tissue disease (CTD) covers all heterogeneous and broad immunological diseases. These immunological diseases are characterized by inflammation, tissue damage, and abnormal repair. Disorders such as fibrotic tissue or loss of function are seen in the degeneration of the target organ. There is a complex relationship between genetic and environmental factors on the basis of these disorders. Vitamin D deficiency has been frequently observed in autoimmune diseases such as systemic lupus erythematosus, diabetes mellitus, and rheumatoid arthritis. Vitamin D deficiency is primarily seen with musculoskeletal complaints and is an early warning of osteomalacia. Muscle weakness is most common in the trunk, shoulders and hips. It is characterized by difficulty in climbing stairs, getting up from sitting or lying position, feeling of heaviness in the legs, duck-like gait, difficulty getting up from a chair, fatigue easily, inability to lift objects with arms and hands. Patients experience decreased exercise capacity as a result of pain and muscle weakness. In addition, vitamin D deficiency causes smooth muscle contraction and an increase in airway inflammation. As a result, it was observed that the disease course and symptoms were more severe in CVD patients with vitamin D deficiency. In a study conducted with rheumatoid arthritis patients, the quality of life, physical activity and depression levels of patients with vitamin D deficiency were compared with the control group. The evaluation parameters of rheumatoid arthritis patients were worse than the control group. Vitamin D levels were compared with sleep, anxiety and depression levels in patients with systemic lupus erythematosus. A positive relationship was found between vitamin D deficiency and sleep disturbance level. It has been observed that the life expectancy of patients with connective tissue disease is significantly reduced compared to healthy ones. Exercise capacity and oxygen consumption decreased in these patients.
Coccygodynia is a painful clinical picture of the sacrococcygeal region.Pain in coccygodynia may be somatic, neuropathic or mixed. There are many studies that emphasize the relationship between vitamin D deficiency and pain.In this study, it is aimed to investigate the severity and type of pain, as well as the effect of vitamin D level on pain in patients with coccygodynia
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 over 12 weeks maintains vitamin D status. This area of research is lacking in the quality of prospective studies. While previous literature has focused on the prevalence of vitamin D status in adults, there is a paucity of data available for children. This study will add to the existing knowledge and provide more specific analysis for children. Hypothesis 1: Increase in vitamin D concentrations will be associated with an improvement in health outcomes including anthropometric measurements, musculoskeletal outcomes, markers of inflammation, nutritional status and bone turnover, lipid profiles, cognitive function, and handgrip strength.
