Introduction Le trouble dépressif majeur est le plus prévalent de tous les troubles psychiatriques et peut affecter la référence à soi. La plupart des stratégies thérapeutiques de la dépression visent à modifier le processus de référence à soi pour rectifier le biais cognitif négatif du patient. L'efficacité de ces traitements est souvent mesurée a...

Introduction Le cancer est un événement traumatique ayant de nombreuses répercussions négatives sur les patients. Parallèlement, il peut aussi résulter en des changements psychologiques positifs perçus chez les individus qui en sont atteints, tels que la modification de leur philosophie de la vie, de leur perception d'eux-mêmes ou encore de leurs r...

Introduction Expanded-criteria donors (ECDs) are used to reduce the shortage of kidneys for transplantation. However, kidneys from ECDs are associated with an increased risk of delayed graft function (DGF), a risk factor for allograft loss and mortality. HYPOREME will be a multicentre randomised controlled trial (RCT) comparing targeted hypothermia...
Article
Full-text available
PurposeKidney transplantation (KT) can impact patients’ evaluation of health-related quality of life (HRQoL) as they adapt to their new life with a graft and its changes. Patients may adapt to KT in a different way, depending on whether they were on dialysis prior to transplantation or not (i.e. preemptive group). This may result in lack of measure...

Article
The growing interest in patient perception and experience in healthcare has led to an increase in the use of patient-reported outcomes (PRO) data. However, chronically ill patients may regularly adapt to their disease and, as a consequence, might change their perception of the PRO being measured. This phenomenon named response shift (RS) may occur...
Article
Full-text available
PurposeMethods for response shift (RS) detection at the individual level could be of great interest when analyzing changes in patient-reported outcome data. Guttman errors (GEs), which measure discrepancies in respondents’ answers compared to the average sample responses, might be useful for detecting RS at the individual level between two time poi...

Addiction is correlated with the dysfunction of definite neural circuitry involving deep as well as superficial brain regions. Among the deep structures are the midbrain ventral tegmental area (VTA) and the nucleus accumbens of the ventral striatum, connected to each other by means of dopaminergic fibers. This pathway is the neural correlate of nor...
