Follicular Fluid Bioavailable Vitamin D and Embryo Quality Markers

To study the possible correlation between bioavailable vitamin D values in follicular fluid and embryo quality markers. To correlate bioavailable Vitamin D values in follicular fluid from large size follicles with embryo euploid status as our main objective. Secondly, looking at morphokinetics and mitochondrial content of these embryos. Taking into ...

Phase N/A

Correlation Between Maternal Vitamin D Level And Preterm Birth

Assessment of correlation between vitamin D level and prevalence of preterm births remains limited. The exact role of vitamin D in preterm birth has not yet been clearly defined ,where some studies showed vitamin D deficiency increased the risk of preterm birth while other studies found no correlation. In this ...

A Long-term Study to Describe the Use of PASCORBIN 7.5 g in Patients With Vitamin C Deficiency

The observational study began on 01 November 2012 and is scheduled for a period of 10 years continued (until 01 November 2022). The duration of the observational study for each patient is not fixed corresponding to the character of a non-interventional study. According to the underlying disease, characterized either acute ...

Magnesium as a Mediator of Bone and Vitamin D Metabolism in Patients on Antiepileptic Drug Therapy

The objective of this study is to determine the role of magnesium on bone and vitamin D metabolism in patients receiving anti-epileptic medications.

Systemic Inflammatory Response: Thiamine and Magnesium Status (Sir TaM Study)

Thiamine and magnesium play a critical role in glucose metabolism and deficiency results in the accumulation of anaerobic metabolites including lactate (1-3). Thiamine requires magnesium to be converted to its active form, thiamine pyrophosphate (TPP) (4). TPP also requires magnesium to achieve activation of TPP dependent enzymes during metabolism of ...

The Effects of Discontinuation of Vitamin K Antagonists on the Rate of Elastin Degradation

Background: Elastin is a unique protein providing elasticity, resilience and deformability to dynamic tissues, such as lungs and vasculature. Elastin fibers are characterized by their high affinity for calcium. However, calcified elastin is more prone to the degrading effects of proteases and, in turn, partially degraded elastin has an even ...

Phase N/A

Evaluation of Metabolic Predictors of Influenza Vaccine Immune Response in the Singapore Elderly Population - the DYNAMIC Trial

Novel, effective influenza vaccination strategies are needed in the elderly who have the highest rate of influenza-related morbidity and mortality. Vaccine efficacy in the elderly is reduced due to immunosenescence and/or, inflamm-aging. This phase IV clinical trial in 240 participants aims to evaluate metabolic predictors of influenza-vaccine specific immune response ...

Phase N/A

Vitamin D Level and Risk of Infections in Cirrhotic Patients

It is widely known that vitamin D has an important role in calcium metabolism and bone mineralization. Its deficiency is related to rickets and osteomalacia in children and adults respectively. Vitamin D had a role in innate and acquired immunity. It increases innate defense and modulates lymphocytes activation, leading to ...

Is There Association Between Vitamin D Levels And Insulin Resistance In Polycystic Ovary Syndrome?

Polycystic ovary syndrome (PCOS) is the most common gynecological endocrinopathy among women of reproductive age. The prevalence of PCOS among such women is estimated to be 6.4% to 6.8% worldwide. PCOS is a heterogeneous androgen excess disorder with different degrees of reproductive and metabolic dysfunctions. There are many considerations to ...
