Autobiographical memory following weight gain in adult patients with Anorexia Nervosa: A longitudinal study.

BACKGROUND: Patients with anorexia nervosa (AN) show overgeneralization of memory (OGM) when generating autobiographical episodes related to food and body shape. These memories are central for the construction of a coherent self-concept, interpersonal relationships, and problem-solving abilities. The current study aims to investigate changes in autobiographical memory following weight gain. METHODS: OGM was assessed with an adapted version of the Autobiographical Memory Test including food-, body-, depression-related, and neutral cues. N = 41 female patients with AN (28 restricting-, 13 binge-eating/purging-subtype; mean disease duration: 4.5 years; mean BMI: 14.5 kg/m2) and N = 27 healthy controls (HC) were included at baseline. After inpatient treatment (mean duration: 11 weeks), 24 patients with AN and 24 age-matched HC were reassessed. Group differences were assessed using independent samples t-tests for cross-sectional comparisons and repeated measures ANOVAs for longitudinal data. RESULTS: At baseline, patients with AN generated significantly fewer specific memories than HC, independent of word category (F(1.66) = 27.167, p < 0.001). During inpatient stay, the average weight gain of patients with AN was 3.1 body mass index points. At follow-up, patients with AN showed a significant improvement in the number of specific memories for both depression-related and neutral cues, but not for food- and body-related cues. CONCLUSIONS: Generalised OGM (i.e., independent of word category) in patients with AN before weight restoration may be a general incapacity to recall autobiographical memory. After weight gain, the previously well-studied pattern of eating disorder-related OGM emerges. The clinical relevance of the continuing disorder-related OGM in patients with AN after weight gain is discussed.

Neurophysiological correlates of disorder-related autobiographical memory in anorexia nervosa.

BACKGROUND: Anorexia nervosa (AN) is characterized by an overgeneralization of food/body-related autobiographical memories (AM). This is regarded as an emotion regulation strategy with adverse long-term effects implicated in disorder maintenance and treatment resistance. Therefore, we aimed to examine neural correlates of food/body-related AM-recall in AN. METHODS: Twenty-nine female patients with AN and 30 medication-free age-sex-matched normal-weight healthy controls (HC) underwent functional magnetic resonance imaging while recalling AMs in response to food/body-related and neutral cue words. To control for general knowledge retrieval, participants engaged in a semantic generation and riser detection task. RESULTS: In comparison to HC, patients with AN generated fewer and less specific AMs in response to food/body-related words, but not for neutral cue words. Group comparisons revealed reduced activation in regions associated with self-referential processing and memory retrieval (precuneus and angular gyrus) during the retrieval of specific food/body-related AM in patients with AN. Brain connectivity in regions associated with memory functioning and executive control was reduced in patients with AN during the retrieval of specific food/body-related AM. Finally, resting-state functional connectivity analysis revealed no differences between groups, arguing against a general underlying disconnection of brain networks implicated in memory and emotional processing in AN. CONCLUSIONS: These results indicate impaired neural processing of food/body-related AM in AN, with a reduced involvement of regions involved in self-referential processing. Our findings are discussed as possible neuronal correlates of emotional avoidance in AN and provide new insights of AN-pathophysiology underscoring the importance of targeting dysfunctional emotion regulation strategies during treatment.

Verbal memory following weight gain in adult patients with anorexia nervosa: A longitudinal study.

BACKGROUND: Patients with Anorexia Nervosa (AN) show a moderate deficit in overall neuropsychological functioning. Since previous studies on memory performance mainly employed cross-sectional designs, the present study aims to investigate changes in verbal memory following weight-gain. METHODS: Verbal memory was assessed with the Wechsler Memory Scale-Revised (WMS-R; 'logical memory'-story-recall-subtest) and the California Verbal Learning Test-II (CVLT-II; 'verbal learning'). Included were 31 female patients with AN (18 restricting-, 13 purging-subtype; average disease duration: 5.1 years; average baseline BMI: 14.4 kg/m2 ) and 24 medication-free normal-weight healthy women adjusted for age at baseline (T0). In a post-treatment assessment of approx. 6 weeks with weight increase (T1), 18 patients with AN and 20 healthy women were assessed again. Group differences in verbal memory (i.e., WMS-R, CVLT-II) were assessed for the baseline comparisons with a multivariate ANOVA and longitudinal data were analysed with repeated measures (RM) ANOVAs. RESULTS: At baseline, patients with AN as compared to healthy women displayed deficits in logical memory. In the follow-up assessment, patients with AN improved their logical memory significantly compared to healthy controls (p < 0.006). Furthermore, groups did not differ in verbal learning neither before nor after inpatient treatment. CONCLUSIONS: Enhanced logical memory in patients with AN following weight-gain is probably due to the impaired memory as compared to healthy controls at T0. A survivorship bias could explain the improved memory performance in longitudinal data in contrast to cross-sectional studies. Patients with AN with poorer memory performance before inpatient treatment are at higher risk to drop out and need support.

The interplay between agency and therapeutic bond in predicting symptom severity in long-term psychotherapy.

This study investigated the interplay between agency and therapeutic bond in predicting patient symptoms in outpatient psychotherapy. A total of N = 731 patients provided measurements of agency (Therapeutic Agency Inventory; TAI), therapeutic bond (bond subscale of Working Alliance Inventory-Short Form Revised [WAI-SR]), and symptoms (Symptom Checklist Short Form [SCL-K11]) every fifth session of long-term treatment for up to 60 sessions. When investigated in separate models, both more agency and a stronger therapeutic bond predicted symptom improvement. However, within-person changes and between-person differences in agency predicted symptom improvement over and above the effects of therapeutic bond. Multilevel response surface analysis was used to further investigate the interplay between agency and therapeutic bond. When both agency and therapeutic bond levels were high, symptoms improved the most. When agency and therapeutic bond ratings differed, symptom ratings were significantly lower when agency exceeded therapeutic bond levels than when therapeutic bond ratings exceeded agency. Findings suggest that both agency and therapeutic bond are important treatment factors, but outcome could be improved when a strong therapeutic bond is combined with an equally strong sense of agency that empowers patients to pursue changes in their lives. When a strong therapeutic bond is present, but the patient feels less agentic, therapists may want to foster agency to improve outcomes. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Multiple Immunostainings with Different Epitope Retrievals-The FOLGAS Protocol.

We describe a sequential multistaining protocol for immunohistochemistry, immunofluorescence and CyTOF imaging for formalin-fixed, paraffin-embedded specimens (FFPE) in the formalin gas-phase (FOLGAS), enabling sequential multistaining, independent from the primary and secondary antibodies and retrieval. Histomorphologic details are preserved, and crossreactivity and loss of signal intensity are not detectable. Combined with a DAB-based hydrophobic masking of metal-labeled primary antibodies, FOLGAS allows the extended use of CyTOF imaging in FFPE sections.

Insight into conflictual relationship patterns: Development and validation of an observer rating scale.

Objective: This study aimed to develop an observer-rated measure of Insight into Conflictual Relationship Patterns (ICR) applicable to audio- or videotapes of psychotherapy sessions and conduct a first psychometric evaluation. Method: We investigated the item properties, principal components, reliability, and validity of the ICR in a naturalistic sample of N = 125 outpatients in psychodynamic psychotherapy. Results: The ICR consists of 12 items that showed adequate item discrimination and item difficulty indices. All items represent one principal component. Using item response theory, discrimination parameters and item characteristic curves revealed that the ability of all items to differentiate patients was adequate to very good. The scale demonstrated good interrater reliability (ICC(3,1) = .76-.93), adequate internal consistency (Cronbach's α = .84), and high retest reliability (r = .91). Regarding validity, the ICR was significantly associated with insight according to the Achievement of Therapeutic Objectives Scale and patient-perceived session depth. Insight at session five predicted a symptomatic increase from session five to session ten. Conclusion: The ICR is an observer-rated measure to assess insight from psychotherapy session recordings that has demonstrated several aspects of reliability and validity. Future studies are needed to clarify the impact of ICR-assessed insight for symptomatic outcome.

[Level of personality functioning and attachment style as predictors of the successful referral to outpatient psychotherapy]. / Persönlichkeitsstruktur und Bindungsstil als Prädiktoren für die erfolgreiche Aufnahme einer ambulanten psychotherapeutischen Behandlung.

Level of personality functioning and attachment style as predictors of the successful referral to outpatient psychotherapy Objectives: Outpatient psychotherapy is a key element in the effective treatment of mental health problems. First results suggest that interpersonal problems lead to difficulties in receiving outpatient psychotherapeutic treatment. The relationship between these difficulties, attachment style, and the level of personality functioning is still unclear. Methods: We invited 1011 patients of a psychosomatic-psychotherapeutic university outpatient clinic to participate in the study. The clinical diagnoses according to ICD-10, as well as symptoms of depression (PHQ-D), and quality of life (SF-36) were recorded. Hypothesized predictors for the successful referral to outpatient therapy were patient age, availability of local outpatient treatment, number of ICD-10 diagnoses, the motivation for psychotherapy (FPTM), fear of stigmatization (Stig-9), level of personality functioning (OPD-SQ), and attachment style (ECR-RD). Results: We were able to catamnestically reassess n = 300 patients (67.3 % of patients initially referred to outpatient therapy). A smaller number of clinical diagnoses, greater availability of psychotherapeutic care and higher therapy motivation, as well as a lower level of personality functioning predicted the successful referral to outpatient psychotherapy, while the combination of impaired personality functioning and avoidant attachment style was a negative predictor. Conclusions: Contrary to expectations, patients with a lower level of personality functioning are more successful in receiving outpatient psychotherapy. However, patients with a combination of impaired personality functioning and a high degree of attachment avoidance run the risk of not asserting their need for treatment.

Therapeutic agency, in-session behavior, and patient-therapist interaction.

OBJECTIVE: The aim of this study was to investigate associations between patients' subjective agency, their observable in-session behavior, and the patient-therapist interaction during the early phase of psychotherapy. METHODS: The sample included 52 depressed patients in psychodynamic psychotherapy. After Session 5, the patients' agency and the quality of the therapeutic alliance were assessed. Based on session recordings, two independent observers rated the patients' involvement, their interpersonal behavior, and the therapists' directiveness. RESULTS: Higher agency was associated with stronger therapeutic alliances. Patients who indicated higher agency in their therapy participated more actively in the session and showed less hostile impact messages. Patients' agency was not related to therapists' directiveness. CONCLUSIONS: Patients' sense of agency in psychotherapy was associated with more active involvement and affiliative interaction. The findings support the idea that patients need to feel capable of acting within and having an influence on their therapy to benefit from it.

Therapeutic Agency Inventory: Development and psychometric validation of a patient self-report.

Objectives: Therapeutic agency is defined as a patient's intentional influence over the process of psychotherapeutic change. However, there is a lack of conceptually sound self-report measures with adequate psychometric properties. The aim of this study was to develop and psychometrically evaluate the patient-rated Therapeutic Agency Inventory (TAI).Method: Based on the literature, we developed items related to therapeutic agency and investigated their psychometric properties in a naturalistic study with a sample of 334 psychotherapy participants. We assessed changes in TAI scores in a subsample of 58 patients over the course of inpatient psychotherapy and related TAI scores to therapeutic improvement.Results: The TAI consists of 15 items. We performed exploratory factor analyses, and the following three factors were extracted: In-session activity, therapy-related processing, and therapist-oriented passivity. Internal consistency was .84 for the total score and ranged between .73 and .80 for each of the factors. The TAI was significantly associated with other psychotherapy process factors, self-efficacy expectations, control beliefs, lower overall psychological distress, and lower depression scores. Changes in agency during psychotherapy predicted therapy outcome, even after controlling for baseline distress.Conclusions: The TAI is a reliable, valid, and change-sensitive self-report instrument that can be used to assess agency in psychotherapy.

Ready to run the wards? - A descriptive follow-up study assessing future doctors' clinical skills.

BACKGROUND: Recent studies have shown that clinical tasks only represent a small percentage in the scope of final-year medical students' activities and often lack sufficient supervision. It appears that final-year medical students are frequently deployed to perform "routine tasks" and show deficits in the performance of more complex activities. This study aimed to evaluate final-year students' clinical performance in multiple impromptu clinical scenarios using video-based assessment. METHODS: We assessed final-year medical students' clinical performance in a prospective, descriptive, clinical follow-up study with 24 final-year medical students during their Internal Medicine rotation. Participating students were videotaped while practicing history taking, physical examination, IV cannulation, and case presentation at the beginning and end of their rotation. Clinical performance was rated by two independent, blinded video assessors using binary checklists, activity specific rating scales and a five-point global rating scale for clinical competence. RESULTS: Students' performance, assessed by the global rating scale for clinical competence, improved significantly during their rotation. However, their task performance was not rated as sufficient for independent practice in most cases. Analysis of average scores revealed that overall performance levels differed significantly, whereby average performance was better for less complex and more frequently performed activities. CONCLUSIONS: We were able to show that students' performance levels differ significantly depending on the frequency and complexity of activities. Hence, to ensure adequate job preparedness for clinical practice, students need sufficiently supervised and comprehensive on-ward medical training.

The Effects of Mitral Valve Repair on Memory Performance, Executive Function, and Psychological Measures in Patients With Heart Failure.

OBJECTIVES: Heart failure (HF) is a prevalent disease that remains costly and associated with a high mortality rate. HF is also associated with poor neurocognitive functioning. For the treatment for HF patients with severe mitral regurgitation, the MitraClip device has emerged as a promising interventional tool that reduces the mitral valve leakage and thus increases cardiac output. Currently, there is only limited knowledge on changes in cognitive and psychosocial functioning before and after the MitraClip intervention. METHODS: Cognitive function (memory and executive function) and psychosocial measures (depression, anxiety, and quality of life) were assessed before and after the MitraClip intervention in 24 HF patients and 23 healthy participants (comparison group). RESULTS: MitraClip intervention in HF patients was followed by improvements in figural long-term memory (p = .003) and executive function (planning ability, p < .001) relative to the comparison group. In addition, the intervention resulted in a significant improvement in depression (p = .002), anxiety (p = .003) and quality of life scores (physical p = .017, mental p = .013) as well as improved 6-minute walk test results over time (p = .002). CONCLUSIONS: The presented data provide evidence of a significant improvement in memory and executive function as well as in depression, anxiety, and quality of life scores in patients with chronic HF after MitraClip intervention. Further research is needed to shed light on the long-term development of cognitive function, psychosocial well-being, and clinical parameters after MitraClip intervention and how these factors depend on one another.

International medical students' expectations and worries at the beginning of their medical education: a qualitative focus group study.

BACKGROUND: The number of international students has increased substantially within the last decade. Due to cultural barriers, this specific group faces diverse challenges. In comparison to German colleagues, international medical students perform significantly lower in clinical examinations and exceed the average duration of study; they suffer from personal distress as well as insufficient support. Within the present study, their individual perspectives, expectations, hopes and fears were examined. METHODS: Four focus groups with first-year international medical students (N = 16) were conducted in October 2013. Each 60- to 90-min discussion was audiotaped, transcribed and analysed using qualitative methods. RESULTS: International medical students go abroad in search of good study-conditions. For the choice of place of study, affordability, social ties as well as an educational system following the achievement principle are decisive factors. While contact with German-students and other international students is seen as beneficial, international medical students are most concerned to encounter problems and social exclusion due to language deficits and intercultural differences. CONCLUSIONS: Facilitating the access to university places, the provision of financial aid and, moreover, social support, nurturing cultural integration, would greatly benefit international medical students. Hereby, the establishment of specific medical language courses as well as programs fostering intercultural-relations could prove to be valuable.

[Stress in Medical Students: A Cross-Sectional Study on the Relevance of Attachment Style and Structural Integration]. / Stresserleben bei Medizinstudierenden: Welche Rolle spielen Bindungserleben und Persönlichkeitsaspekte?

INTRODUCTION: From year one of studying medicine an increase of psychological stress is found. The relationship between the occurrence of this stress and attachment patterns or structural personality functions remains unclear. The present study aimed at investigating whether a relationship between the enduring personality variables, attachment style and level of structural integration of the personality, and acute stress experience at the beginning of medical students' studies exists. MATERIAL & METHODS: In this study, all students in the first semester of medicine were invited to participate in a study to identify stress factors via questionnaire (MBI-SS, PSQ, PHQ-9, GAD-7) in the WS 2013/2014. Simultaneously, the predominant attachment style (RQ-2) and structural abilities (OPD-SFK) were evaluated. RESULTS: The study included 293 students (return: 91.3%). Securely attached students experienced significantly less stress than insecurely attached students (p=0.019). Students with a high level of structural integration showed significantly less stress burden (p<0.001) and lower exhaustion- (p<0.001) and cynicism values (p<0.001), while showing a higher experience of self-efficacy (p<0.001). The influence of attachment behavior on stress experience is mediated by the level of the structural integration of the personality. DISCUSSION: Significant correlations exist between attachment style and the level of structural integration of the personality, and burnout risk as well as stress burden. The level of structural integration of the personality mediates the relationship between the attachment-related "model of self" and stress experience, i. e. a positive "model of self" can have a stress-protective effect when good structural abilities are present. Practical implication: An insecure attachment style and a low level of structural integration may be associated with higher stress experience when transitioning to study. The results suggest that the enduring personality variable attachment style, mediated by the level of structural integration of the personality, leads to higher stress and burnout experience. Affected students could be supported by early preventive measures enabling the sustainable preparation for this transitional period. Longitudinal prospective studies are needed to explore if the assumption is applicable that pre-existing vulnerabilities in school are exacerbated at this transitional stage.

Functionalization of biomineral reinforcement in crustacean cuticle: Calcite orientation in the partes incisivae of the mandibles of Porcellio scaber and the supralittoral species Tylos europaeus (Oniscidea, Isopoda).

In arthropods the cuticle forms an exoskeleton with its physical and chemical properties adapted to functions of distinct skeletal elements. The cuticle of the partes incisivae (PI) in mandibles of terrestrial isopods is a composite of chitin-protein fibrils/fibres and minerals. It consists of an unmineralized tip, a middle region with organic fibrils reinforced mainly with amorphous calcium phosphate and a base region mineralized with amorphous calcium carbonate and calcite. In this study we extend our work on the structure and material properties of the incisive cuticle employing electron backscatter diffraction (EBSD), and investigate calcite orientation patterns in the PI of two terrestrial isopod species from different habitats. We trace small-scale differences in texture sharpness and calcite microstructure, and compare calcite organization and orientation patterns in the PI with those in the tergites of the same isopod species. We observe that in the PI calcite orientation, the degree of crystal alignment, and mode of crystalline domain assemblage is highly varied within short length scales. This contrasts to calcite organization in the tergite cuticle, where calcite has only one specific texture pattern. Such a large range in the variation of calcite organization has not been observed in other carbonate biological hard tissues, such as shells and teeth, where one specific texture and microstructure prevails. Thus, the investigated isopod species are able to control crystallization of the amorphous carbonate precursor in a differential way, most probably related to the function of the individual skeletal element and the animals' behavior.

Digital rectal examination skills: first training experiences, the motives and attitudes of standardized patients.

BACKGROUND: Physical clinical examination is a core clinical competence of medical doctors. In this regard, digital rectal examination (DRE) plays a central role in the detection of abnormalities of the anus and rectum. However, studies in undergraduate medical students as well as newly graduated doctors show that they are insufficiently prepared for performing DRE. Training units with Standardized Patients (SP) represent one method to deliver DRE skills. As yet, however, it is little known about SPs' attitudes. METHODS: This is a qualitative study using a grounded theory approach. Interviews were conducted with 4 standardized patients about their experiences before, during and after structured SP training to deliver DRE competencies to medical students. The resulting data were subjected to thematic content analysis. RESULTS: Results show that SPs do not have any predominant motives for DRE program participation. They participate in the SP training sessions with relatively little prejudice and do not anticipate feeling highly vulnerable within teaching sessions with undergraduate medical students. CONCLUSIONS: The current study examined SPs' motives, views, expectations and experiences regarding a DRE program during their first SP training experiences. The results enabled us to derive distinct action guidelines for the recruitment, informing and briefing of SPs who are willing to participate in a DRE program.

Characteristics of Disorder-Related Autobiographical Memory in Acute Anorexia Nervosa Patients.

OBJECTIVE: First studies revealed overgeneral autobiographical memories in anorexia nervosa (AN) patients. The aim of the present study was to investigate frequency, generalization and valence of autobiographical memories in AN patients in response to eating disorder-related cue words. METHOD: Autobiographical memory was examined in 21 AN patients and 21 healthy controls (HC) using a modified version of the Autobiographical Memory Test, incorporating body-related, food-related, perfectionism-related, depression-related and neutral cues. RESULTS: Anorexia nervosa patients recalled fewer and more general autobiographical memories compared with HC. For eating disorder-related cues as against neutral ones, AN patients compared with HC showed fewer memories for food-related and body-related cues, an elevated overgeneralization for food-related cues, while the valence of the retrieved memories was more negative in response to body-related cues. DISCUSSION: This study detects disorder-related autobiographical memory alterations in AN, which are intensified in response to symptom-related cues. The findings are discussed with regard to their maladaptive function in emotion regulation.

Function-related adaptations of ultrastructure, mineral phase distribution and mechanical properties in the incisive cuticle of mandibles of Porcellio scaber Latreille, 1804.

In terrestrial isopods the mandibles consist of a corpus carrying strong muscle tissue, and a pars incisiva (PI) that cuts dry leaves into smaller ingestible pieces. We studied the cuticle of the PI of Porcellio scaber in order to understand region-dependent differences in its ultrastructure, composition, and the resulting mechanical properties, employing several microscopic and analytical techniques as well as nanoindentation experiments. The cuticle of the incisive tip is not mineralized and consists of an unusually thick epicuticle containing thin fibrils, two subjacent cuticular layers, and a central core containing fibrils of different orientation, either longitudinal or circumferential. A thick epicuticle of the middle region just behind the tip projects long epicuticular extensions into the subjacent endocuticle, likely to prevent delamination. A distinct exocuticular layer is lacking in the middle region. Most chitin-protein fibrils within the endocuticle are oriented in parallel pointing towards the tip. Surprisingly, the middle region is mineralized by amorphous calcium phosphate (ACP) only. Near the base, ACP is successively replaced by amorphous calcium carbonate and calcite is restricted to a distal layer in the base. At the transition between middle and base, the epicuticle forms a hybrid material containing fibrils of the exocuticle. Nanoindentation experiments reveal an increase of the stiffness and hardness from the tip towards the base and significantly higher values on transversal in comparison to longitudinal planes. The results suggest that ultrastructure and composition are adapted for conveying high forces from a rather thin cutting edge to the stable base of the PI.

Voluntary undergraduate technical skills training course to prepare students for clerkship assignment: tutees' and tutors' perspectives.

BACKGROUND: Skills lab training has become a widespread tool in medical education, and nowadays, skills labs are ubiquitous among medical faculties across the world. An increasingly prevalent didactic approach in skills lab teaching is peer-assisted learning (PAL), which has been shown to be not only effective, but can be considered to be on a par with faculty staff-led training. The aim of the study is to determine whether voluntary preclinical skills teaching by peer tutors is a feasible method for preparing medical students for effective workplace learning in clerkships and to investigate both tutees' and tutors' attitudes towards such an intervention. METHODS: A voluntary clerkship preparation skills course was designed and delivered. N = 135 pre-clinical medical students visited the training sessions. N = 10 tutors were trained as skills-lab peer tutors. Voluntary clerkship preparation skills courses as well as tutor training were evaluated by acceptance ratings and pre-post self-assessment ratings. Furthermore, qualitative analyses of skills lab tutors' attitudes towards the course were conducted following principles of grounded theory. RESULTS: Results show that a voluntary clerkship preparation skills course is in high demand, is highly accepted and leads to significant changes in self-assessment ratings. Regarding qualitative analysis of tutor statements, clerkship preparation skills courses were considered to be a helpful and necessary asset to preclinical medical education, which benefits from the tutors' own clerkship experiences and a high standardization of training. Tutor training is also highly accepted and regarded as an indispensable tool for peer tutors. CONCLUSIONS: Our study shows that the demand for voluntary competence-oriented clerkship preparation is high, and a peer tutor-led skills course as well as tutor training is well accepted. The focused didactic approach for tutor training is perceived to be effective in preparing tutors for their teaching activity in this context. A prospective study design would be needed to substantiate the results objectively and confirm the effectiveness.
