RESUMO
Objective: Transference is a psychological process where feelings and attitudes towards a familiar person are unconsciously redirected to another. This phenomenon can be activated by physical resemblance, including facial features. Despite its potential therapeutic significance, little research has investigated transference processes in individuals with psychiatric conditions. Here, we explored how patients with borderline personality disorder (BPD)-characterized, among other features, by unstable relationships, self-damaging impulsivity, and suicidal ideation-would exhibit transference of negative and positive attributes. Method: We performed an experiment where BPD participants and a control group with no prior psychiatric history completed a face-rating task. The task involved an evaluation of images of strangers who resembled significant others in terms of facial features. Results: Our results indicated that transference effects were elicited in both groups. Notably, there were significant differences in ratings assigned to significant others, whereby participants with BPD displayed transference of negative attributes more and positive attributes less intensely than healthy controls, which, in part, correlated with attachment anxiety. Conclusions: Our findings align with the tendency in BPD to perceive interpersonal relationships and emotions more negatively. They have potential implications for psychotherapeutic approaches in treating patients with BPD and our understanding of underlying pathophysiological mechanisms of BPD itself.
RESUMO
Limb-girdle muscular dystrophy (LGMD) type R1 (LGMDR1) is the most common subtype of LGMD in Europe. Prospective longitudinal data, including clinical assessments and new biomarkers such as quantitative magnetic resonance imaging (qMRI), are needed to evaluate the natural course of the disease and therapeutic options. We evaluated eight thigh and seven leg muscles of 13 LGMDR1 patients (seven females, mean age 36.7 years, body mass index 23.9 kg/m2) and 13 healthy age- and gender-matched controls in a prospective longitudinal design over 1 year. Clinical assessment included testing for muscle strength with quick motor function measure (QMFM), gait analysis and patient questionnaires (neuromuscular symptom score, activity limitation [ACTIVLIM]). MRI scans were performed on a 3-T MRI scanner, including a Dixon-based sequence, T2 mapping and diffusion tensor imaging. The qMRI values of fat fraction (FF), water T2 relaxation time (T2), fractional anisotropy, mean diffusivity, axial diffusivity and radial diffusivity were analysed. Within the clinical outcome measures, significant deterioration between baseline and follow-up was found for ACTIVLIM (p = 0.029), QMFM (p = 0.012). Analysis of qMRI parameters of the patient group revealed differences between time points for both FF and T2 when analysing all muscles (FF: p < 0.001; T2: p = 0.016). The highest increase of fat replacement was found in muscles with an FF of between 10% and 50% at baseline. T2 in muscles with low-fat replacement increased significantly. No significant differences were found for the diffusion metrics. Significant correlations between qMRI metrics and clinical assessments were found at baseline and follow-up, while only T2 changes in thigh muscles correlated with changes in ACTIVLIM over time (ρ = -0.621, p < 0.05). Clinical assessments can show deterioration of the general condition of LGMDR1 patients. qMRI measures can give additional information about underlying pathophysiology. Further research is needed to establish qMRI outcome measures for clinical trials.
