Correlation between vitamin D level and coronary artery calcification.

Background: Considering the role of Vitamin D in cardiovascular disease (CVD) and the relationship between coronary artery calcification (CAC) and CVD, we aimed to investigate the association between the serum level of Vitamin D and CAC.

Materials And Methods: This was a cross-sectional study on 67 consecutive patients who were referred for performing computed tomography angiography. We used Spearman correlation to evaluate the relationship between Vitamin D and CAC and then linear regressions to control for demographics and vascular risk factors.

Angiogenesis and Minimal Residual Disease in Patients with Acute Myeloid Leukemia.

Acute myeloid leukemia (AML) is the most prevalent acute leukemia in adults. Bone marrow angiogenesis is crucial for pathogenesis of leukemia, and increasing bone marrow Mean Vascular Density (MVD) and level of angiogenesis factors are seen in patients with AML. Higher level of bone marrow MVD is associated with poor prognosis of AML according to previous studies.
