Background: Vitamin D deficiency is common during pregnancy and childbirth. Recent findings suggest that vitamin D deficiency is associated with adverse pregnancy outcomes. This study was performed to determine the association between low levels of maternal serum vitamin D and some adverse pregnancy outcomes such as premature rupture of embryonic membranes. Materials and Methods: 73 pregnant w...
Background: The effects of vitamin D in skeletal system, biological metabolism and immune system function are well shown. Cholecalciferol (vitamin D3) and ergocalciferol (vitamin D2) are two major types of vitamin D. Vitamin D deficiency is widely in human population and vitamin D intoxication is very rare. Case Description: The patient is 37-years old bodybuilder man who referred to emergency...
Burden of Chronic Obstructive Pulmonary Disease (COPD) is substantial and increasing in the world. There are controversial reports regarding vitamin D supplementation in COPD. We investigated relationship between vitamin D3 (Cholecalciferol) supplementation with Health Related Quality of Life (HRQOL) and symptom recovery in AECOPD patients with concurrent Vitamin D Deficiency (VDD). A placebo-c...
The specificity of gentamicin for vitamin E deficiency-associated oxidative stresses in the renal proximal convoluted tubules is apparently related to its ability to increasingly facilitate generation of radical species in mitochondria. To determine the ways in which vitamin E manage the currently processes, we conducted a prospective study aimed to investigate the tubular preserving effect of ...
Background Vitamin D is a fat-soluble vitamin that has an important function in bone metabolism, muscle activity, nervous system, and immunity. In this study, we compared the vitamin D level of children with congenital heart disease (CHD) with healthy control. Materials and Methods This case-control study was conducted on 56 ...
Background: Thyroid cancer is the most common endocrine malignancy. Accounting for approximately 1-2% of all cancers. Thyroid cancers have been divided into four main types: papillary, follicular, medullary and anaplastic. The active form of vitamin D (1,25- (OH) 2-vitamin D3) by binding to its receptor, using genomic and non-genomic mechanisms inhibits the proliferative effect of TSH on thyroi...
Background: Animal models and observational studies have suggested a favorable role of vitamin D in male reproduction. However, randomized clinical trials investigating the effect of vitamin D supplementation on male fertility are limited. Therefore, this study aimed to examine the effect of vitamin D supplementation on semen quality, reproductive hormones, and anthropometric measurements in vi...
Background: The 25-hydroxyvitamin D3(25-OH D3)deficiency is a common problem worldwide, and it is aprevalent incidence in neonates. Different studies investigated the relationship of vitamin D deficiency with neonatal mortality and morbidity. This study aimed to evaluate the relationship between vitamin D deficiency and respiratory distress in preterm neonates.Methods: A prospective cohor...
Background: Animal and in vitro studies have shown that 25-OH vitamin D plays a significant role in different parts of body. Few data exist about the role of 25- OH vitamin D in reproduction. Insufficient levels during pregnancy are potentially associated with increased risk of preeclampsia, insulin resistance and gestational diabetes mellitus. Recently, few studies have assessed the prognostic...
Background: Vitamin D is an important factor for bone growth. Vitamin D deficiency reduces absorption of calcium and causes rickets and also increases bone fragility. In addition, Vitamin D deficiency has exoskeleton side effects, such as increased risk of cancer, cardiovascular disease, infections and autoimmune diseases. In most cases, vitamin D intake is not enough in dietary food supplies....
