Viktoriya Vitkova

 

Viktoriya est doctorante en première année de thèse en cotutelle entre l’Université de Lorraine (laboratoire Interpsy, Prof. Ariane Bazan) et l’Université Libre de Bruxelles (laboratoire de Neurophysiologie et Biomécanique du mouvement, Prof. Ana Maria Cebolla Alvarez).

Elle est titulaire du Master en Social, Cognitive and Affective Neuroscience, obtenu à la Freie Universität Berlin et du Master en Sciences Psychologiques, à finalité psychologie clinique et psychopathologie, obtenu à l’Université Libre de Bruxelles.

Sa double formation reflète son goût pour l’interdisciplinarité et son souhait de tisser des liens entre la recherche et la pratique clinique, les neurosciences et la psychologie, le corps et l’esprit.

Le sujet de sa thèse vise à étudier la relation entre les oscillations alpha, l’inhibition linguistique et les processus primaires et secondaires décrits par Freud. A cette fin, elle utilise la technique d’électroencéphalographie (EEG), couplée à des outils linguistiques développés par l’équipe de Prof. Ariane Bazan dans le but de mesurer de manière objective les processus primaires et secondaires. Le titre provisoire de la thèse: “Le rôle des oscillations alpha dans l’inhibition/le refoulement de stimuli linguistiques : une étude à l’interface de la psychanalyse et des neurosciences motrices”.

Increased Serum Neurofilament Light and Thin Ganglion Cell–Inner Plexiform Layer Are Additive Risk Factors for Disease Activity in Early Multiple Sclerosis. Neurology – Neuroimmunology Neuroinflammation8(5), e1051. https://doi.org/10.1212/NXI.0000000000001051

Abstract
Objective  To investigate the association of combined serum neurofilament light chain (sNfL) and retinal optical coherence tomography (OCT) measurements with future disease activity in patients with early multiple sclerosis (MS).
Methods  We analyzed sNfL by single molecule array technology and performed OCT measurements in a prospective cohort of 78 patients with clinically isolated syndrome and early relapsing-remitting MS with a median (interquartile range) follow-up of 23.9 (23.3–24.7) months. Patients were grouped into those with abnormal or normal sNfL levels, defined as sNfL ≥/<80th percentile of age-corrected reference values. Likewise, patients were grouped by a median split into those with thin or thick ganglion cell and inner plexiform layer (GCIP), peripapillary retinal nerve fiber layer, and inner nuclear layer in nonoptic neuritis eyes. Outcome parameters were violation of no evidence of disease activity (NEDA-3) criteria or its components.
Results Patients with abnormal baseline sNfL had a higher risk of violating NEDA-3 (hazard ratio [HR] 2.28, 95% CI 1.27–4.09, p = 0.006) and developing a new brain lesion (HR 2.47, 95% CI 1.30–4.69, p = 0.006), but not for a new relapse (HR 2.21, 95% CI 0.97–5.03, p = 0.058). Patients with both abnormal sNfL and thin GCIP had an even higher risk for NEDA-3 violation (HR 3.61, 95% CI 1.77–7.36, p = 4.2e−4), new brain lesion (HR 3.19, 95% CI 1.51–6.76, p = 0.002), and new relapse (HR 5.38, 95% CI 1.61–17.98, p = 0.006) than patients with abnormal sNfL alone.
Conclusions In patients with early MS, the presence of both abnormal sNfL and thin GCIP is a stronger risk factor for future disease activity than the presence of each parameter alone.
