Present study showed that VSD was the most common CHD subtype followed by family history, familial marriage, extra cardiac anomalies (ECAs), birth weight, and maternal concomitant disease. But there was a controversial relationship between birth order and drug history in CHD.

Vitamin D or cholecalciferol, as a steroidal hormone, regulates the calcium homeostasis, and bone formation with reabsorption through kidneys, parathyroid glands and bowel. There are at least 800 human genes connected with vitamin D. Previous research has confirmed the relationship between vitamin D and colorectal cancers, infections, heart diseases, multiple sclerosis (MS), bone disorders, inflammatory and autoimmune diseases, inflammatory bowel diseases, diabetes mellitus type-I and II and also progression of kidney disease. However, the relationship of vitamin D deficiency and developing of breast cancer, rheumatoid arthritis and osteoporosis is unknown. In fact, the effect of vitamin D deficiency on pathogenesis of different diseases is controversial. To cope with vitamin D deficiency, there are different recommendations such as daily intake of vitamin D supplements and more exposure to sunlight.

In a study on 100 end-stage renal disease, we found ETS arteriovenous fistulas had less complications compared to the STS technique in this patients. Please cite this paper as: Introduction:Chronic Kidney Disease (CKD) is a global health problem which is growing in prevalence. Hemodialysis is the most common treatment for end-stage renal disease (ESRD) which requires a permanent vascular access. Vascular accesses should have a good patency and low complication. Objectives: The present study aimed to compare side-to-side (STS) versus end-to-side (ETS) methods in antecubital arteriovenous fistulas in dialysis patients. Patients and Methods: In this randomized, single-blind clinical trial, 100 ESRD patients who scheduled for hemodialysis were divided into two groups. STS arteriovenous anastomosis was employed in one group and in the other, the ETS approach was conducted. Follow ups were done after 1, 8, and 24 weeks to detect fistula maturation and immediate or delayed complications. Results:The STS anastomosis group demonstrated higher rates of delayed maturation, vascular aneurism, and venous hypertension syndrome than ETS anastomosis group. The ETS group, however, showed higher rates of venous thrombosis and vascular stenosis. Overall, the rate of complications was 24% and 8% for STS and ETS anastomosis group respectively (P = 0.03). Conclusion:In comparison, ETS arteriovenous fistulas involve less complications than STS method in ESRD patients. However, more thrombosis and stenosis detected by ETS method. ETS arteriovenous fistulas had less delayed maturation, aneurism, venous hypertension and overall complications than STS approach. ETS arteriovenous fistulas contributes to establishing a more stable connection to hemodialysis machine to conduct a more effective hemodialysis.
