Delayed onset of efficacy of antidepressants and a high proportion of depressed patients being poor or non-responders to antidepressants are well known clinical challenges. Therefore, it seems to be necessary to identify predictors for response and - even more important - for remission. It has been suggested that reduction of depressive symptoms at an early stage of antidepressant treatment may predict treatment outcome. Our objective was to test, if this hypothesis derived from randomized controlled studies (RCTs) in outpatients, would be confirmed in a large naturalistic study in a cohort of inpatients with major depression. Patients were treated with various antidepressants and co-medication according to the protocol based on evidence-based clinical guidelines. ⋯ The results support earlier findings that early improvement in the first two weeks may predict with high sensitivity later response and remission, even in hospitalized patients suffering from a more severe degree of depression. Since we used a naturalistic study design, the data may be considered as a replication of previous results drawn from RCTs in a naturalistic environment. We found a global antidepressant effect which was consistent across treatment subgroups regarding sensitivity values. However, we are aware of the inability of effectiveness studies to draw causal treatment relationships from the uncontrolled approach. Nevertheless, the replication of previous results might indicate that a drug switch during treatment in case of lack of early improvement could be accelerated.

Comparative Study
The relationship of bulimia and anorexia nervosa with bipolar disorder and its temperamental foundations.
Earlier studies have suggested a relationship between bipolar disorder (BP) and eating disorders (ED), more specifically, bulimia nervosa (BN) and bipolar II disorder (BP-II). In the present report we extend this relationship to broader definitions of bipolarity. ⋯ In line with previous reports we describe an association between bulimia nervosa and bipolar disorder. Furthermore we report a relationship between lifetime bulimia and anorexia and cyclothymic and related affective temperaments.

Comparative Study
Economic impact of non-persistence to antidepressant therapy in the Quebec community-dwelling elderly population.
In a real-life setting, differences across newer antidepressants in patterns of use remain poorly explored, particularly in the older patients despite the high prevalence of late-life depression. ⋯ As found in other populations, non-persistence with antidepressant treatment is very frequent in the Quebec elderly population. Products associated with poor persistence result in increased health care costs. Hence, intervention programs aimed at improving persistence would optimize the use of health care resources and result in economic advantages.

Schizoaffective disorder shares clinical characteristics with schizophrenia and affective disorders, with patients experiencing concurrent manic, mixed, or depressive episodes during psychosis. Because efficacy may be better in schizoaffective disorder than schizophrenia, this post-hoc analysis examines the efficacy, safety, and tolerability of aripiprazole in patients with schizoaffective disorder. ⋯ Aripiprazole was efficacious and well tolerated in patients with schizoaffective disorder.
