Prevalence and correlates of DSM-5 bipolar and related disorders and hyperthymic personality in the community.

BACKGROUND: To 1) establish the lifetime and 12-month prevalence of DSM-5 bipolar and related disorders including the new algorithmically defined conditions grouped within Other Specified Bipolar and Related Disorders (OSBARD) as well as hyperthymic personality in a randomly selected community sample, and 2) determine the clinical relevance of the OSBARD category in terms of sociodemographic characteristics, course, comorbidity and treatment patterns by comparing the subjects of this category to those with bipolar-I (BP-I), bipolar-II (BP-II), major depressive disorder (MDD), and those with no history of mood disorders. METHODS: The semi-structured Diagnostic Interview for Genetic Studies was administered by masterslevel psychologists to a random sample of an urban area (n=3'719). RESULTS: The lifetime prevalence was 1.0% for BP-I, 0.8% for BP-II, 1.0% for OSBARD and 3% for hyperthymic personality. Subjects with OSBARD were more severely affected than subjects without a history of mood disorders regarding almost all clinical correlates. Compared to those with MDD, they also revealed an elevated risk of suicidal attempts, lower global functioning, more treatment seeking and more lifetime comorbidity including anxiety, substance use and impulse-control disorders. However, they did not differ from subjects with BP-II. LIMITATIONS: Small sample sizes for bipolar and related disorders and potential inaccurate recall of symptoms. CONCLUSIONS: The modifications of diagnostic criteria for manic/hypomanic episodes according to the DSM-5 only marginally affect the prevalence estimates for BP-I and BP-II. The new DSM-5 OSBARD category is associated with significant clinical burden, is hardly distinct from BP-II with respect to clinical correlates and deserves similar clinical attention.

Pathology and biology of peripheral T-cell lymphomas.

Peripheral T-cell lymphomas (PTCLs) represent a heterogeneous group of more than 20 neoplastic entities derived from mature T cells and natural killer (NK) cells involved in innate and adaptive immunity. With few exceptions these malignancies, which may present as disseminated, predominantly extranodal or cutaneous, or predominantly nodal diseases, are clinically aggressive and have a dismal prognosis. Their diagnosis and classification is hampered by several difficulties, including a significant morphological and immunophenotypic overlap across different entities, and the lack of characteristic genetic alterations for most of them. Although there is increasing evidence that the cell of origin is a major determinant for the delineation of several PTCL entities, however, the cellular derivation of most entities remains poorly characterized and/or may be heterogeneous. The complexity of the biology and pathophysiology of PTCLs has been only partly deciphered. In recent years, novel insights have been gained from genome-wide profiling analyses. In this review, we will summarize the current knowledge on the pathobiological features of peripheral NK/T-cell neoplasms, with a focus on selected disease entities manifesting as tissue infiltrates primarily in extranodal sites and lymph nodes.

Early clarification processes in clients presenting with borderline personality disorder: Relations with symptom level and change

Clarification-Oriented Psychotherapy (COP), an integrative treatment form with a basis in process-experiential psychotherapy, is particularly relevant for clients with Personality Disorders (PDs). We argue here that two related core therapeutic COP principles, "dual action regulation" and "interactional games" have consequences for symptom severity and therapeutic outcome for clients with PDs. A high quality COP clarification process requires that client's interactional games may be quickly assessed and treated in all (preferably early) therapy sessions. These processes can be observed and measured using the observer-rated Bochum Process and Relationship Rating Scales (BPRRS) which measure both clients' and therapists' contributions to the quality of the clarification processes engaged in therapy. This measure has been successfully applied to COP-therapies, but not, as yet, to therapies other than experiential, nor to specific client populations such as borderline personality disorder. The present study is a first attempt to evaluate the application of COP processes to other therapies and populations. We measured action regulation and interactional games using the BPRRS during intake sessions of a 10-session psychodynamic treatment of borderline personality disorder for a total of N = 30 clients and N = 8 therapists. Significant relationships were found between the client's degree of interactional games and both pretherapy symptom level and symptom change across therapy. These results are discussed in the context of Clarification-Oriented Psychotherapy, and more generally Person-Centered and Process-Experiential Psychotherapies. The potential relevance of the findings for psychodynamic psychotherapists are explored as well as the potential usefulness of taking into account a detailed analysis of interactional games for the training of psychotherapists working with any model of therapy working with clients presenting with BPD.
