RESUMO

In the present study, we explore the role of attachment for microstructural white matter (WM) changes in adolescents with anorexia nervosa (AN) before and after exposure to short-term and nutritional treatment. The case sample consisted of 22 female adolescent inpatients with AN (mean age: 15.2 ± 1.2 years) and the control sample were 18 gender-matched healthy adolescents (mean age: 16.8 ± 0.9 years). We performed a 3T MRI in the patient group during the acute state of AN and after weight restoration (duration: 2.6 ± 1 months) and compared the data to a healthy control group. To classify attachment patterns, we used the Adult Attachment Projective Picture System. In the patient sample, over 50% were classified with an attachment trauma/unresolved attachment status. Prior to treatment exposure, fractional anisotropy (FA) reductions and concordant mean diffusivity (MD) increases were evident in the fornix, the corpus callosum and WM regions of the thalamus, which normalized in the corpus callosum and the fornix post-therapy in the total patient sample (p < 0.002). In the acute state, patients with an attachment trauma demonstrated significant FA decreases compared to healthy controls, but no MD increases, in the corpus callosum and cingulum bilaterally, which remained decreased after therapy. Attachment patterns seem to be associated with region-specific changes of WM alterations in AN.

RESUMO

BACKGROUND: Mostly, visual food stimuli paradigms for functional Magnetic Resonance Imaging are used in studies of eating disorders. However, the optimal contrasts and presentation modes are still under discussion. Therefore, we aimed to create and analyse a visual stimulation paradigm with defined contrast. METHODS: In this prospective study, a block-design fMRI paradigm with conditions of randomly altering blocks of high- and low-calorie food images and images of fixation cross was established. Food pictures were rated in advance by a group of patients diagnosed with anorexia nervosa to address the dedicated perception of patients with eating disorders. To optimize the scanning procedure and fMRI contrasts we have analysed neural activity differences between high-calorie stimuli versus baseline (H vs. X), low-calorie stimuli versus baseline (L vs. X) and high- versus low-calorie stimuli (H vs. L). RESULTS: By employing the developed paradigm, we were able to obtain results comparable to other studies and analysed them with different contrasts. Implementation of the contrast H versus X led to increased blood-oxygen-level-dependent signal (BOLD) mainly in unspecific areas, such as the visual cortex, the Broca´s area, bilaterally in the premotor cortex and the supplementary motor area, but also in thalami, insulae, the right dorsolateral prefrontal cortex, the left amygdala, the left putamen (p < .05). When applying the contrast L versus X, an enhancement of the BOLD signal was detected similarly within the visual area, the right temporal pole, the right precentral gyrus, Broca´s area, left insula, left hippocampus, the left parahippocampal gyrus, bilaterally premotor cortex and thalami (p < .05). Comparison of brain reactions regarding visual stimuli (high- versus low-calorie food), assumed to be more relevant in eating disorders, resulted in bilateral enhancement of the BOLD signal in primary, secondary and associative visual cortex (including fusiform gyri), as well as angular gyri (p < .05). CONCLUSIONS: A carefully designed paradigm, based on the subject's characteristics, can increase the reliability of the fMRI study, and may reveal specific brain activations elicited by this custom-built stimuli. However, a putative disadvantage of implementing the contrast of high- versus low-calorie stimuli might be the omission of some interesting outcomes due to lower statistical power. Trial registration NCT02980120.


Although the relationship with food is crucial for living, its underlying mechanisms (e.g., neurological, cognitive, physiological) are still not fully discovered. The development of functional magnetic resonance imaging made it possible to explore brain's responses to images of food. However, a proper methodological analysis of the research paradigm is still lacking. Here, we present the optimization of visual food stimuli paradigms achieved by comparison of neural activations of 20 female healthy adolescents after applying particular contrasts (i.e., high- versus low-calorie food images, high-calorie food images versus baseline, low-calorie food images versus baseline). Application of the contrast high- versus low-calorie food images resulted in stronger neural activation in visual cortex (including fusiform gyri) and angular gyri. This study highlights the importance of choosing a proper contrast regarding the study hypothesis, as it may induce more specific results. However, it may lead to loss of some outcomes, due to lower statistical power. Additionally, we have performed an evaluation of visual food stimuli chosen by patients diagnosed with anorexia nervosa. They have selected images of the most and the least willingly eaten meals. Although they didn't know the exact calorie content, they chose intuitively photos later classified as extremely high- or low-caloric.

RESUMO

BACKGROUND AND RESEARCH QUESTION: The Austrian Society for Child and Adolescent Psychiatry, Psychosomatics and Psychotherapy (ÖGKJP) is publishing a series of articles in a special issue of Neuropsychiatrie dealing with the current provision of care in child and adolescent psychiatry. Aim of this article is to give an overview of provision of care for children and adolescents with mental health problems in Austria, Germany, and Switzerland and then draw conclusions for the Austrian child and adolescent psychiatric care landscape. METHOD: First, epidemiologic data as well as different traditions and treatment philosophies and their effect for provision of care in child and adolescent psychiatry in Austria, Germany and Switzerland are presented. Subsequently, data of provided child and adolescent psychiatric care in Austria and Germany are presented and related to each other. RESULTS AND CONCLUSIONS: On the basis of the data presented, the current deterioration of mental health in children and adolescents due to the pandemic as well as the deficit of available inpatient beds (0.03-0.09) there is an urgent need for action in Austrian provision of child and adolescent psychiatric care. An improvement of the structural deficits in the child and adolescent psychiatric research and care landscape, a significant increase of capacities for inpatient treatment, day-care as well as outpatient treatment with establishment of modern treatment options such as home treatment is necessary.

RESUMO

The aim of the present study was to investigate whether grey matter (GM) reductions in acute anorexia nervosa (AN) are (i) valid for adolescents (age 14-18 years), (ii) reversible following short-term psychotherapeutic and nutritional therapy and (iii) depend on psychological components like attachment trauma. 3T MRI including a high-resolution T1 MPRAGE was performed in 22 female adolescents in the acute state of AN (age: 15.2 ± 1.2 years) and after weight restoration (duration: 2.6 ± 1 months, n = 18) and compared with 18 gender-matched healthy controls. The Adult Attachment Projective Picture System was used to classify resolved and unresolved attachment patterns. GM decreases were localized in extensive cortical areas including the insula, prefrontal and cingulate cortices as well as subcortical regions during acute AN, which partially increased after therapy with a relative sparing of the hippocampus and parahippocampal gyrus. The resolved group showed more GM recovery in regions of the left hippocampus and parahippocampal gyrus, bilateral cerebellar regions, right precuneus and adjacent cingulate cortices relative to the unresolved pattern. Structural anomalies in adolescent AN that recovered after treatment may be primarily the consequence of malnutrition, whereas several regions did not display significant recovery. Attachment status seems to influence region-specific GM recovery.

RESUMO

OBJECTIVE: Knowledge on gut-brain interaction might help to develop new therapies for patients with anorexia nervosa (AN), as severe starvation-induced changes of the microbiome (MI) do not normalise with weight gain. We examine the effects of probiotics supplementation on the gut MI in patients with AN. METHOD: This is a study protocol for a two-centre double-blind randomized-controlled trial comparing the clinical efficacy of multistrain probiotic administration in addition to treatment-as-usual compared to placebo in 60 patients with AN (13-19 years). Moreover, 60 sex- and age-matched healthy controls are included in order to record development-related changes. Assessments are conducted at baseline, discharge, 6 and 12 months after baseline. Assessments include measures of body mass index, psychopathology (including eating-disorder-related psychopathology, depression and anxiety), neuropsychological measures, serum and stool analyses. We hypothesise that probiotic administration will have positive effects on the gut microbiota and the treatment of AN by improvement of weight gain, gastrointestinal complaints and psychopathology, and reduction of inflammatory processes compared to placebo. CONCLUSIONS: If probiotics could help to normalise the MI composition, reduce inflammation and gastrointestinal discomfort and increase body weight, its administration would be a readily applicable additional component of multi-modal AN treatment.

RESUMO

TransIdentity - Identity Development Among Adolescent Trans*people Identity development is one of the most important developmental tasks of adolescence. Adolescents whose gender identity does not correspond to the gender assigned at birth (trangender people) are also faced with this challenge, as are cis-gender adolescents of the same age. This study is the first to examine the personality function of identity in transgender adolescents. Based on the self report of a population of 69 adolescents from the outpatient unit for gender dysphoria the extent of identity diffusion measured by AIDA (Assessment of Identity Development in Adolescence) was compared with the values of the normative sample consisting of German-speaking pupils. Both the overall construct of identity diffusion and the areas of continuity and coherence showed average values in the examined young people, which speaks against pathological identity development. Nevertheless, identity diffusion was found in over a third (36 %). Most notably the aspect of stabilising relationships and roles was above average, which suggests that positive role identification from the areas of culture, family and body-self is present to a lesser extent than in the norm sample. The identity-stabilizing feeling of social anchoring appears to be impaired in the young transidents studied.

RESUMO

Therapeutic Models for Children and Adolescents with Gender Dysphoria: Overview with Focus on Austrian Treatment Reality Young people whose experienced gender differs from their aligned sex are increasingly visible in public life as well as in the medical care system. For those children and adolescents, who can experience a high degree of suffering because of the discrepancy between aligned sex and desired gender, treatment guidelines have been developed. In this short narrative review, classification options, epidemiological data, health-care data and treatment guidelines are presented with an emphasis on the Austrian health care system.

RESUMO

The aim of the present study was to compare acute effects of a climbing intervention (CI) on affective responses with a different exercise intervention (swimming, SI) and an occupational therapy intervention (OTI) in children and adolescents during in-patient treatment for mental health disorders. The following study was designed as a cross-over study. Participants completed three single 60 min interventions of CI, SI and OTI. Affective responses were assessed pre and post intervention and at 20 and 40 min during intervention. The sample consisted of 33 children and adolescents in mental-health inpatient care (ᴓage: 13.3 ± 2.2 years, ♀=39.4%). A significant time effect was seen in all interventions in increasing positive and reducing negative affect, p<.028, eta²>0.144. Repeated measures ANOVAs revealed a significant time by intervention effect for affective valence (p=.011, eta²=0.09), but not for perceived activation, favouring CI over SI and OCT between pre-test and the first 20 or 40 min, respectively. All interventions showed similar effects on affective responses pre to post interventions. CI seems to increase affective valence more strongly during intervention compared to SI and OTI. The present results may have implications for therapy adherence and acute emotion regulation in children and adolescent in-patients with mental health disorders.

RESUMO

Multiple Substance Abuse as a Form of High Risk Behavior in Adolescence We identify multiple substance abuse as a form of high risk behavior in adolescence based on a sample of in-patient adolescents. 43 adolescents were treated for substance abuse over the course of 20 months. 70 % reported the use of three or more different drugs, with an average of 5,35 consumed substances. The most commonly abused substance was cannabis, followed by synthetic drugs such as cocaine or ecstasy. We observed a high rate of non-suicidal self-injury as a comorbidity of multiple substance abuse in our sample. 73,3 % of adolescents with high risk, multiple substance abuse fulfilled diagnostic criteria for non-suicidal self-injury.

RESUMO

Peer victimisation (PV) in childhood and adolescence can come along with psychological stress through the life span. Even though there exist a large number of questionnaires that measure PV, evidence of the use is often missing. Particularly instruments for capturing cyberbullying lack psychometric calculations such as factor analysis for investigating scales and data on validity and reliability. An exception constitutes the Multidimensional Offline and Online Peer Victimization Scale (MOOPV) of Sumter et al., which is only available in Dutch. This questionnaire is not medium-specifically designed, has been psychometrically properly explored, and differentiates between direct and indirect as well as online and offline PV. The present study aims to investigate the psychometric properties of the German version of the Multidimensional Offline and Online Peer Victimization Scale (MOOPV). The factor structure, validity and reliability was examined in a sample of 777 pupils aged 10-20. Confirmatory factor analysis supported the original four-factor model. The scales direct offline, indirect offline, direct online, and indirect online demonstrated high internal reliability and construct validity. The MOOPV can be used as a validated instrument in research and practice to capture PV in childhood and adolescence.

RESUMO

Childhood Maltreatment and Non-Suicidal Self-Injury - the Impact of Emotion Regulation Non-suicidal self-injury (NSSI) is a common phenomenon in adolescence. Furthermore, it is often associated with maltreatment during childhood. One factor determining the relation between childhood maltreatment and NSSI is maladaptive emotion regulation strategies. The current study examines this relation in adolescent psychiatric inpatients (n = 97). Adolescents engaging in NSSI present maladaptive strategies in emotion regulation more frequently. In addition, they experienced maltreatment in childhood more often than inpatients not engaging in NSSI. Further, partial mediation was established among childhood emotional abuse and neglect, NSSI and maladaptive emotion regulation.

RESUMO

Assessment and Therapy of Adolescent Identity Diffusion Identity diffusion, one of the main diagnosis criteria for borderline personality disorder (BPD), is characterized by a lack of coherent sense of self and of significant others, paired with a painful sense of incoherence. The revision of the age limit for the diagnosis of personality disorders in DSM-5 has opened the doors to research on diagnosis and treatment of BPD in adolescence. This paper offers a summary of past and present work on the diagnosis and therapy of identity disturbance in adolescent patients.
