Atherosclerosis vascular damage in elderly athletes and sedentary people
No full textThe objective of this study was to determine the degree of vascular atherosclerotic damage at the carotid and femoral levels in a group of subjects over sixty years old practicing endurance sports. Using high-resolution Doppler-color flow ultrasonography the authors carried out a vascular screening, comparing two distinct groups of subjects, the first consisting of 20 elderly male subjects (age 65.6 +/-5.6 years) practicing endurance sports (runners) and the second of 20 subjects of the same gender and age (63.5 +/-4.5 years), clinically healthy, but leading a sedentary life. All subjects were nonsmokers, nondiabetics, with normal lipid values and normal blood pressure. The authors examined the internal, external, and common carotid arteries, bilaterally, as well as the common femoral, deep femoral, and superficial femoral arteries of both legs. For each vessel they documented: (1) presence of plaques, (2) position and quantity of the plaques, (3) stenosis percentage produced by the plaques, (4) echographic structure of the plaques. In the group of sportsmen they calculated a global score of atherosclerotic damage of 5.58 +/-2.21. This is statistically significant (P<0.001) as compared with the global score observed in the sedentary group (9.24 +/-3.9, range 6-14). The sportsmen exhibited small atherosclerotic plaques that were not hemodynamically significant; these plaques were present in 7 subjects (35%). In 4 of them (20%) the lesions were located in one carotid artery system. In the other 3 subjects (15%) the lesions were identified in one femoral artery system. In none of the sportsmen were they able to demonstrate simultaneous atherosclerosis of carotid and femoral arteries. In the sedentary subjects, atherosclerotic lesions were identified in 15 of them (75%). In 2 subjects hemodynamically significant plaques were located in one carotid artery system. In the other 13 subjects the plaques found were not hemodynamically significant; in 6 subjects this type of lesion was present in both femoral and carotid arteries; in 5 the lesions were located in one carotid artery system, and in 2 in one femoral artery system. In conclusion, endurance exercise appears to protect the elderly against atherosclerotic vascular damage

Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
