| Abstract |
The role of decreased active vitamin D levels on vascular calcification has not been elucidated in hemodialysis (HD) patients. The aim of the present study was to evaluate the relationship between progression of aortic arch calcification (AoAC) and prescribed dose of 1alpha-hydroxy vitamin D. The enrolled study subjects were 65 (40 men and 25 women) HD patients. Calcification of the aortic arch was semiquantitatively estimated with a score (AoACS) on plain chest radiology. Change in AoACS (DeltaAoACS) was obtained by subtracting the baseline AoACS value from the follow-up AoACS value. The second assessment was performed from 2 years after the first determination. The nonprogressors (63.2 +/- 14.5 years) were significantly younger than the progressors (68.2 +/- 10.8 years) (P = 0.0419). In addition, prescribed dose of 1alpha-hydroxy vitamin D3 was significantly higher in the nonprogressors (125.5 +/- 109.1 microg) than progressors (84.8 +/- 81.1 microg) (P = 0.0371). Multiple regression analysis revealed prescribed dose of 1alpha-hydroxy vitamin D(3) (beta value = -0.324, P = 0.0051) as well as DBP (beta value = -0.418, P = 0.007), serum levels of P (beta value = 0.333, P = 0.006) and C-reactive protein (beta value = 0.237, P = 0.0048) to be significant independent determinants of DeltaAoACS. In conclusion, the evaluation of AoACS on chest radiography is a very simple tool in HD patients. Active vitamin D therapy seems to protect patients from developing vascular calcification. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 26 March 2010.
All research outputs
#7,855,444
of 23,815,455 outputs
Outputs from Heart and Vessels
#115
of 693 outputs
Outputs of similar age
#50,067
of 168,451 outputs
Outputs of similar age from Heart and Vessels
#1
of 2 outputs
Altmetric has tracked 23,815,455 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 693 research outputs from this source. They receive a mean Attention Score of 3.1. This one has gotten more attention than average, scoring higher than 64% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 168,451 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 21st percentile – i.e., 21% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 2 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
