Filter by:Periodontitis; is an inflammatory disease of tissues characterized by bone destruction around the teeth. Vitamin D plays an important role in several inflammatory diseases by promoting the expression of inflammatory cytokines such as interleukin IL-1, IL-6, and IL-1β, which are directly related to periodontal attachment loss and bone demineralization. These facts suggest that vitamin D may be associated with periodontal disease. Many studies have been conducted on the relationships between serum 25-hydroxyvitamin D (25(OH)D) levels, periodontal disease, and tooth loss. However, as far as we know, there is no study on the relationship between periodontitis and free and bioavailable 25 (OH) vitamin D. In our study, over the age of 35; two groups will be formed, consisting of 40 healthy and 40 periodontitis individuals. Serum total 25 (OH) D level and vitamin D binding protein level will be analyzed by ELISA method, and bioavailable 25 (OH) D level will be calculated using total 25 (OH) D and vitamin D binding protein levels. The aim of this study; To evaluate the total, free and bioavailable 25 (OH) vitamin D levels of patients with periodontitis by comparing them with healthy controls, and to investigate whether bioavailable 25 (OH) D plays a role in the pathogenesis of periodontitis or can be a simple marker of disease activity in the light of these findings.
High-Dose Vitamin D3 in the Treatment of Human Immune Deficiency Virus Patients, A Double-Blind Randomized Control Trial Human immunodeficiency virus is a key challenge for global health. Vitamin D deficiency is common in people living with HIV infection. Antiretroviral therapy may create unique risk factors for vitamin D insufficiency, including alterations of vitamin D metabolism by ART.
GraviD is a multi-ethnic population-based pregnancy cohort. Pregnant women were invited to participate in the GraviD study when registering for antenatal care in parts of the region of Västra Götaland in Sweden in 2013-2014. All women registering for antenatal care were eligible for inclusion, as long as the pregnancy had not exceeded 16 gestational weeks. In total, 2125 pregnant women were recruited in gestational week 12 during two time-periods; fall 2013 and spring 2014. Blood sampling was performed in gestational week <17 and again at gestational week >31 by midwifes. After delivery, the maternity records were obtained, to collect information on child's gender, birth weight and length and other possible birth outcomes.
The lack of a pharmacological treatment in the COVID-19 pandemic has pushed scientists to search for this issue. Maintaining optimal health is parallel to adequate and balanced nutrition. In this context, can the protective properties of vitamin D play an important role in this pandemic? brought with it the thought. In this study, it was aimed to examine the effect of vitamin D on mortality and hospital stay in COVID-19 disease.
A Disintegrin-like And Metalloprotease with Thrombospondin type 1 motif 13 (ADAMTS13) deficiency was incriminated in poor prognosis, high probability of serious complications and mortality in acute myeloid leukemia (AML) patients. Interleukin 6 (IL-6) produced from AML blasts decreases Cluster of differentiation 34 positive(CD34+) cells differentiation, and inhibits the ADAMTS13 actions. Vitamin D "as an Immune-modulator" inhibits the pro-inflammatory cytokines including IL-6. So, supplementation of vitamin D might help down regulation of interleukin-6 production. Aim of the study To evaluate the potential relation between Vitamin D status, ADAMTS13 and IL-6 in AML patients. Objectives 1. Assess Vitamin D level in AML patients 2. Assess ADAMTS13 and IL-6 in AML patients 3. Correlate between Vitamin D level and both of ADAMTS13 and IL-6
Type 1 diabetes mellitus (T1DM) is an immune-mediated disease characterized by diminished insulin secretion due to damage to islets of Langerhans in the pancreas, which eventually results in high levels of glucose in the blood. According to World Diabetes Foundation, in Palestine, 4.4% of diabetic patients are diagnosed with T1DM, while 95.3% are diagnosed with type 2 diabetes (T2DM) (World Diabetes Foundation, 2020). Observational studies have reliably provided evidence that T1DM patients with acceptable glycemic control have higher 25(OH)D levels than T1DM with lesser glycemic control. Additionally, it has been specified by some of the research-based studies that there is a strong connection between the deficiency of vitamin D and the incidence of T1DM. In interventional studies of T1DM children and adults, repletion of vitamin D in deficient individuals improved HbA1c in a period of 12 weeks. Participants were more likely to achieve HbA1c < 7.8% if they had higher 25(OH)D levels on week 12 than on baseline, especially if 25(OH)D levels were exceeded 51 nmol/l. According to the Food and Drug Administration (FDA), The Institute of Medicine's (IOM) recommended Upper Limit (UL) for chronic Vitamin D intake for infants (children less than 1 year of age) is 25 mcg/day (1,000 IU/d), and for children age 1 year and older the recommended UL is 50 mcg/day (2,000 IU/d) (Institute of Medicine Standing Committee on the Scientific Evaluation of Dietary Reference Intakes, 1997). Despite a large amount of evidence from observational and experimental studies supporting the effects of vitamin D on glucose metabolism and the immune system, results from clinical studies remain inconsistent, which makes it impossible to recommend vitamin D supplementation for the treatment of T1DM. Therefore, this study aimed to investigate the status of vitamin D among T1DM children for vitamin and to examine the effects of vitamin D supplementation on glycemic control in children with T1DM. This is the first randomized controlled trial that studied the effects of vitamin D supplementation on glycemic control among T1DM children in the Gaza Strip, Palestine.
The main medical and social purpose of the project "It's trendy to be healthy!" is the promotion of healthy lifestyles and healthy eating among student youth. The relevance of this project is beyond doubt, as the WHO called obesity a non-communicable epidemic, and according to research by the Jane Schiller University of Germany (Germany), as mentioned above, Ukraine topped the list of the countries with high mortality due to malnutrition
The aim of the current study was to investigate the effect of exercise-induced lipolysis on vitamin D status in obese children. Two types of exercises that have different effects on lipolysis were used. Lipolysis was assessed via monitoring the level of plasma level of the free fatty acids and glycerol. Vitamin D was assessed through 25 (OH)D plasma levels.
Children with Down's syndrome (DS) are more liable to vitamin D deficiency. Treating this deficiency with supplements is associated with the risk of intoxication due to increased intestinal absorption or decreased vitamin D metabolism. The aim of the study was to compare the effect of two exercise intensities on the modulation of vitamin D and Parathormone (PTH) levels in children with DS.
