Although dissociative phenomena belong to the diagnostic criteria of borderline personality disorder (BPD) and are of high clinical relevance, their predictive significance with regard to the treatment outcome has hardly been investigated. Because some therapeutic and experimental studies suggest that dissociation can impede emotional learning and thus adversely affect the response to psychotherapy, we examined this issue in patients with BPD. In this naturalistic psychotherapy study we assessed 342 patients with BPD at the beginning and end of inpatient dialectical behavioural therapy (DBT) with self-report measures for dissociation (Questionnaire on dissociative symptoms, FDS, as German version of the Dissociative Experiences Scale, DES) as well as general and borderline specific pathology (Brief Symptom Inventory, BSI; Borderline Symptom List, BSL) and quality of life (SF-12).

There is a growing consensus that emotion dysregulation is the defining feature of borderline personality disorder, but there are also persisting competing views on the pathology and dimensional structure of the disorder. The "Impulsivity and Emotion Dysregulation Scale" (IED-27) is already being used for assessing patients with borderline personality disorder. The particular aim of this study was to gain evidence of the dimensional structure of the disorder by confirmatory factorial analysis.

Background: A routinely collected big data set was analyzed to determine the effectiveness of naturalistic inpatient treatment and to identify predictors of treatment outcome and discontinuation.

Methods: The sample included 878 patients with borderline personality disorder who received non-manualized dialectic behavioral therapy in a psychosomatic clinic. Effect sizes (Hedge's g) were calculated to determine effectiveness.

Borderline personality disorder (BPD) is a severe mental disorder which is accompanied by impaired functioning, complex psychosocial problems and incurs large costs. However, it rarely has been examined whether BPD symptoms form a hierarchical (Mokken) scale, which would imply that symptoms are ordered along a latent dimension of borderline severity. In this study the data from 1,198 inpatients of a psychosomatic clinic were examined.

Background: Information regarding the clinical characteristics and outcomes of kidney transplant recipients (KTRs) with > 25 years of graft survival is limited.

Methods: In this single-center observational study, we characterized KTRs transplanted between 1973 and 1992 with active follow-up as of July 31, 2017.

Results: We identified 112 patients with > 25 years of allograft function.

The emotionally instable personality disorder, mostly called borderline disorder, shows central abnormalities in impulse control as well as instability of mood and identity. It is composed of behaviour problems in creating relationships and in self-management, first of all by high psychophysiological tension. The prevalence of this disorder is 10 % in outpatients and 20 % in inpatients and has therefore high relevance for the medical-psychotherapeutic care system.

To examine the effectiveness of dialectical behavior therapy for inpatients with borderline personality disorder (BPD), small sample sizes and, predominantly, tests of statistical significance have been used so far. We studied 1423 consecutively admitted individuals with BPD, who were seeking a 3-month inpatient treatment. They completed the Borderline Symptom List (BSL) as the main outcome measure, and other self-rating measures at pre- and post-treatment.

Background: Tolerance to noninherited maternal antigens has provided clinical advantage when kidney transplants are exchanged between siblings but not when mother herself is the donor. This paradox prompted us to revisit the "two-way" hypothesis of transplant tolerance--that the immune status of both the organ recipient and the organ donor critically influences allograft outcome.

Methods: We obtained peripheral blood monocyte cells from 29 living donor-recipient pairs before transplant and used the trans-vivo-delayed type hypersensitivity assay to measure immune regulation in both the recipient antidonor and donor antirecipient directions.
