Background: The metabolic and cardiac impact of a cycling effort on blood biology is not very well described in the literature. We aimed to measure the concentration of different biomarkers (cardiac and metabolic) released during an international cycling race. Methods: Venous blood samples of 15 young men (25.1 ± 6.4 y.o.) were collected just before (T1), just after (T2), 3 hours (T3) after an international cycling race of 179.6 kilometers in Belgium for the determination of cardiac and metabolic biomarkers: red blood cell (RBC), haemoglobin (HgB), creatinin (Cr), highly sensitive troponin T (hsTnT), myoglobin (MYO) and NT-proBNP. All automated assays were performed according to the manufacter’s specifications. For the statistical analysis, an Anova calculated with the Statistica Software version 9.1 was used. Results: RBC and HgB levels varied significantly between T0 and T3 (respectively p=0.0026, and p=0.002). Cr concentration also varied significantly between all times (T0-T1:p<0.0001, T1-T3:p=0.0326 and T0-T3 p=0.0001). These changes might be related to renal flow depletion during exercice. MYO increased significantly between T0 and T1 (p<0.0001), but quickly decreased between T1 and T3, however the T3 level stay higher than T0 (p=0.014). The stress delivered from the physical activity performed during the race induced a significant variation of hsTnT which increased significantly between T0 and T1 (p<0.0001) and stayed higher 3 hours after the end of the exercise (T0-T3: p<0.0001) .The intense exercise delivery by the race induced a significant variation of NT-proBNP, that followed the same kinetic of hsTnT but in smaller proportion. We noticed variations statistically significant between T0 and T1 and between T0 and T3 for NT-proBNP. These increases of cardiac biomarkers were significant but reasonable and could not allow us to talk about cellular necrosis or irreversible injury. Conclusion: Our results show that stress generated by a cycling race could be the cause for the different metabolic variations observed. Troponin T stays without a doubt the most specific marker for stress related to myocardial tissue. Its increase can then be considered as being of interest. [less ▲]

L'article explore les fondements idéologiques qui ont présidé à la construction de la coalition libérale-socialiste-écologiste qui a dirigé la Belgique de 1999 à 2003. Si les écologistes se sont imposés in extremis à la faveur de la crise de la dioxine en 1999, cela faisait un certain temps qu'un accord entre socialistes et libéraux pour mettre les partis chrétiens dans l'opposition était "dans l'air" : il s'agissait d'en finir avec un certain nombre de "verrous moraux" venus du monde catholique (notamment autour des valeurs familiales), qui apparaissaient de moins en moins en phase avec l'opinion publique. Cette mise à l'arrière-plan du clivage gauche/droite au profit du clivage laïque/clérical a sans doute bousculé plus durablement que prévu le paysage idéologique. [less ▲]
