RESUMEN
We aimed to explore whether a migraine with aura (MA) is associated with structural changes in tracts of a white matter and to compare parameters of diffusivity between subgroups in migraineurs. Forty-three MA and 20 healthy subjects (HS), balanced by sex and age, were selected for this study. Analysis of diffusion tensor parameters was used to identify differences between MA patients and HS, and then between MA subgroups. A diffusion tensor probabilistic tractography analysis showed that there is no difference between MA patients and HS. However, using more-liberal uncorrected statistical threshold, we noted a trend in MA patients toward lower diffusivity indices of selected white matter tracts located in the forceps minor and right anterior thalamic radiation (ATR), superior longitudinal fasciculus (temporal part) (SLFT), cingulum-cingulate tract, and left uncinate fasciculus. Migraineurs who experienced somatosensory and dysphasic aura, besides visual symptoms, had tendency toward lower diffusivity indices, relative to migraineurs who experienced only visual symptoms, in the right inferior longitudinal fasciculus, forceps minor, and right superior longitudinal fasciculus (parietal part), SLFT, and cingulum-angular bundle. Aura frequency were negatively correlated with axial diffusivity and mean diffusivity of the right ATR (partial correlation = - 0.474; p = 0.002; partial correlation = - 0.460; p = 0.002), respectively. There were no significant differences between MA patients and HS, neither between MA subgroups. Migraineurs with abundant symptoms during the aura possibly have more myelinated fibers relative to those who experience only visual symptoms. Lower diffusivity indices of the right ATR are linked to more frequent migraine with aura attacks.

Serbia's interventional community has been facing the multifaceted challenge of an ageing population with cardiovascular diseases as the primary cause of death nationwide, coronary artery disease (CAD) being the most prevalent subset. The following two fields of activity have marked the trajectory of progress in the field of interventional cardiology in Serbia: first, the expansion of the infrastructure, mainly through the opening of new catheterisation laboratories across all of the country's administrative regions, which has resulted in better accessibility to coronary interventions for the general population; second, the creation of national platforms for continuous education, training and the promotion of clinical research in interventional cardiology, with close programmatic links to European Association of Percutaneous Cardiovascular Interventions (EAPCI)-based educational initiatives, including the curriculum for interventional cardiology. As growth seems to be inherent to the concept of progress, we report here on the expanding numbers of coronary interventions in the period between January 2010 and December 2015, and the early experiences with structural heart interventions in Serbia.
