Subtypes of narcissistic personality disorder based on psychotherapy process: A longitudinal nonparametric analysis.
The present study aims at empirically exploring subtypes of narcissistic personality disorder (NPD), based on patient descriptors of the psychotherapeutic process. Subtype identification and characterization of NPD is central, in particular, to increase diagnostic precision, linking categorical and dimensional conceptualizations of psychopathology, and to individualize treatments. A total of N = 161 patients diagnosed with NPD undergoing clarification-oriented psychotherapy were included in the present reanalysis of a naturalistic pre-post process-outcome study. At three crucial time-points of the therapy (Sessions 15, 20, and 25), the patient's in-session quality of content, process, and relationship are assessed using intensive video- and audio analyses. Levels of psychopathology were assessed using self-reported questionnaires. Data were analyzed using longitudinal nonparametric analysis. Based on in-session processes across three time-points, a two-subtype solution was retained (optimal vs. suboptimal process qualities). Optimal process quality of time was linked with the intensity of narcissistic symptoms; suboptimal process quality was linked with a variety of general symptom loads and problematic personality traits. The two empirical subtypes were predicted by the quality of real-life functioning with an accuracy of more than 92% and were partially associated with outcome. NPD may be empirically differentiated between patients engaging in optimal psychotherapy process versus those who engage in suboptimal psychotherapy process. This differentiation has reliable clinical predictors at the outset of treatment. The present study has implications in terms of personalizing psychotherapy for patients presenting NPD, or pathological narcissism. (PsycInfo Database Record (c) 2021 APA, all rights reserved)
Importance of early weight changes to predict long-term weight gain during psychotropic drug treatment.
BACKGROUND: Psychotropic drugs can induce substantial weight gain, particularly during the first 6 months of treatment. The authors aimed to determine the potential predictive power of an early weight gain after the introduction of weight gain-inducing psychotropic drugs on long-term weight gain.
METHOD: Data were obtained from a 1-year longitudinal study ongoing since 2007 including 351 psychiatric (ICD-10) patients, with metabolic parameters monitored (baseline and/or 1, 3, 6, 9, 12 months) and with compliance ascertained. International Diabetes Federation and World Health Organization definitions were used to define metabolic syndrome and obesity, respectively.
RESULTS: Prevalences of metabolic syndrome and obesity were 22% and 17%, respectively, at baseline and 32% and 24% after 1 year. Receiver operating characteristic analyses indicated that an early weight gain > 5% after a period of 1 month is the best predictor for important long-term weight gain (≥ 15% after 3 months: sensitivity, 67%; specificity, 88%; ≥ 20% after 12 months: sensitivity, 47%; specificity, 89%). This analysis identified most patients (97% for 3 months, 93% for 12 months) who had weight gain ≤ 5% after 1 month as continuing to have a moderate weight gain after 3 and 12 months. Its predictive power was confirmed by fitting a longitudinal multivariate model (difference between groups in 1 year of 6.4% weight increase as compared to baseline, P = .0001).
CONCLUSION: Following prescription of weight gain-inducing psychotropic drugs, a 5% threshold for weight gain after 1 month should raise clinician concerns about weight-controlling strategies
Change in Biased Thinking in a Treatment Based on the Motive-Oriented Therapeutic Relationship for Borderline Personality Disorder.
Biased thinking is a common feature of patients presenting with borderline personality disorder (BPD). For the treatment of BPD, it was shown that the individualizing of the treatment, by using the motive-oriented therapeutic relationship (MOTR), had a beneficial short-term effect on process and outcome. So far, it remains unclear what the role of early change in biased thinking is in these treatments. The present study aims to assess whether there is a link between the MOTR, change in biased thinking, and outcome. The sample (N = 60) is based on a randomized controlled trial with two conditions: (a) 30 patients in a 10-session version of psychiatric management, and (b) 30 patients in a 10-session version of psychiatric management augmented with the MOTR. For each patient, three sessions (intake, middle, late) were selected, transcribed, and rated using the Cognitive Errors Rating Scale (CERS). An overall decrease of negative cognitive errors during 10 sessions of treatment was observed, independently of the treatment condition. No specific effect related to change in biased thinking may be attributed to the individualizing of the treatment. These results are discussed with regard to mechanisms of change in treatments for BPD, in particular with regard to the central role that biased thinking, as well as the MOTR, might play early in treatment
Self-Assessed Competency at Working with a Medical Interpreter Is Not Associated with Knowledge of Good Practice
BACKGROUND: Specific knowledge and skills are needed to work effectively with an interpreter, but most doctors have received limited training. Self-assessed competency may not accurately identify training needs. PURPOSES: The purpose of this study is to explore the association between self-assessed competency at working with an interpreter and the ability to identify elements of good practice, using a written vignette. METHODS: A mailed questionnaire was sent to 619 doctors and medical students in Geneva, Switzerland. RESULTS: 58.6% of respondents considered themselves to be highly competent at working with a professional interpreter, but 22% failed to mention even one element of good practice in response to the vignette, and only 39% could name more than one. There was no association between self-rated competency and number of elements mentioned. CONCLUSIONS: Training efforts should challenge the assumption that working with an interpreter is intuitive. Evaluation of clinicians' ability to work with an interpreter should not be limited to self-ratings. In the context of large-scale surveys, written vignettes may provide a simple method for identifying knowledge of good practice and topics requiring further training
Modelling the human epidermis in vitro: tools for basic and applied research
Culture models of tissues and organs are valuable tools developed by basic research that help investigation of the body functions. Modelling is aimed at simplifying experimental procedures in order to better understand biological phenomena, and consequently, when sufficiently characterized, culture models can also be utilized with high potential in applied research. In skin biology and pathology, the development of cultures of keratinocytes as monolayers has allowed the elucidation of most functional and structural characteristics of the cell type. Beside the multiple great successes that have been obtained with this type of culture, this review draws attention on several neglected characteristics of monolayer cultures. The more sophisticated models created in order to reconstruct the fully differentiated epidermis have followed the monolayers. The epidermal reconstruction produces all typical layers found in vivo and thus makes the model much less simple, but only this kind of model allows the study of full differentiation in keratinocyte and production of the cornified barrier. In addition to its interest in basic research, the reconstructed epidermis is currently gaining a lot of interest for applied research, particularly as an alternative to laboratory animals in the chemical and cosmetic industry. Today several commercial providers propose reconstructed skin or epidermis, but in vitro assays on these materials are still under development. In order to be beneficial at long term, the validation of assays must be performed on a material whose availability will not be interrupted. We warn here providers and customers that the longevity of in vitro assays will be guaranteed only if these assays are done with well-described models, prepared according to published procedures, and must consider having a minimum of two independent simultaneous producers of similar material
Social interaction patterns, therapist responsiveness, and outcome in treatments for borderline personality disorder.
Inflexible social interaction patterns are defining features of borderline personality disorder (BPD). Specific beliefs about the self and others may be activated across interaction situations, often leading to instable relationships. It may be pivotal to address these difficulties in early treatment phases, through appropriate therapist responsiveness, which means an adaptation of therapist's activity to their client's behaviours using emerging information in the process (Stiles, 2009, Clinical Psychology: Science and Practice, 16, 86).
In this process-outcome study, responsiveness is operationalized by the motive-oriented therapeutic relationship (Caspar, 2007, Handbook of psychotherapeutic case formulations, 2nd ed., 251-289, Guilford), based on the Plan analysis case formulation. The present study assesses the interplay between social interaction problems and therapist responsiveness, explaining symptoms at discharge and the therapeutic alliance.
In total, N = 50 clients with BPD entered the study, and standard and responsive treatments were compared. Social interaction patterns were assessed by the newly developed Borderline Interaction Patterns Scale (BIPS), applied to recorded material of three sessions per therapy. Outcome was measured by general symptoms (OQ-45), borderline symptoms (BSL-23), interpersonal problems (IIP), and the therapeutic alliance (WAI).
Results suggest that in standard treatment, social interaction patterns are neither related to outcome nor the therapeutic alliance. In responsive treatment, more activation of social interaction patterns predicted better outcome on IIP and lower therapist ratings of the alliance.
The conclusions seem promising for specific effectiveness of responsive treatments in particular in the interpersonal problem area of BPD. Identifying social interaction patterns early in treatment may be a crucial pathway to change for BPD.
Responsive therapy activating social interaction patterns may be crucial for better outcome. Future research should focus on mechanisms of change in early treatment phases for BPD. New scale for assessing social interaction patterns specific to borderline personality disorder

Rhythmic variability between speakers:articulatory, prosodic and linguistic factors
Between-speaker variability of acoustically measurable speech rhythm [%V, ΔV(ln), ΔC(ln), and Δpeak(ln)] was investigated when within-speaker variability of (a) articulation rate and (b) linguistic structural characteristics was introduced. To study (a), 12 speakers of Standard German read seven lexically identical sentences under five different intended tempo conditions (very slow, slow, normal, fast, very fast). To study (b), 16 speakers of Zurich Swiss German produced 16 spontaneous utterances each (256 in total) for which transcripts were made and then read by all speakers (4096 sentences; 16 speaker × 256 sentences). Between-speaker variability was tested using analysis of variance with repeated measures on within-speaker factors. Results revealed strong and consistent between-speaker variability while within-speaker variability as a function of articulation rate and linguistic characteristics was typically not significant. It was concluded that between-speaker variability of acoustically measurable speech rhythm is strong and robust against various sources of within-speaker variability. Idiosyncratic articulatory movements were found to be the most plausible factor explaining between-speaker differences
Generation of Trophoblast Stem Cells from Rabbit Embryonic Stem Cells with BMP4
Trophoblast stem (TS) cells are ideal models to investigate trophectoderm differentiation and placental development. Herein, we describe the derivation of rabbit trophoblast stem cells from embryonic stem (ES) cells. Rabbit ES cells generated in our laboratory were induced to differentiate in the presence of BMP4 and TS-like cell colonies were isolated and expanded. These cells expressed the molecular markers of mouse TS cells, were able to invade, give rise to derivatives of TS cells, and chimerize placental tissues when injected into blastocysts. The rabbit TS-like cells maintained self-renewal in culture medium with serum but without growth factors or feeder cells, whilst their proliferation and identity were compromised by inhibitors of FGFs and TGF-β receptors. Taken together, our study demonstrated the derivation of rabbit TS cells and suggested the essential roles of FGF and TGF-β signalings in maintenance of rabbit TS cell self-renewal
