Abstract
Remission and response were suggested as the most relevant outcome criteria for the treatment of depression. There is still marked uncertainty as to what cut-offs should be used on current depression rating scales. The goal of the present study was to compare the validity of different HAMD, MADRS and BDI cut-offs for response and remission. The naturalistic prospective study was performed in 12 psychiatric hospitals in Germany. All evaluable patients (n=846) were hospitalized and had to meet DSM-IV criteria for major depressive disorder. Biweekly ratings were assessed using HAMD-21, MADRS and BDI. A CGI-S score of 1 and a CGI-I score of at least 2 was used as the primary comparative measure of remission and response, respectively. A HAMD-21 cut-off ≤7 (AUC: 0.92), HAMD-17 cut-of ≤6 (AUC: 0.90), MADRS cut-off ≤7 (AUC: 0.94) and BDI cut-off ≤12 (AUC: 0.83) were associated with a maximum of specificity and sensitivity for defining remission. A minimum decrease of 47% of the HAMD-21 (AUC: 0.90), ≤57% for HAMD-17 (AUC: 0.89), ≤ 46% for MADRS (0.91) and a decrease of 47% for the BDI baseline score (AUC: 0.78) best corresponded CGI response criteria. Our data largely confirmed currently used remission and response criteria in naturalistically treated patients.

Abstract
BACKGROUND Because of strict inclusion and exclusion criteria, results drawn from placebo-controlled randomized antidepressant efficacy trials may not be transferable to real-world patients. METHOD This study was performed from March 2000 to September 2005 as a prospective, multicenter follow-up. Patients were recruited from February 2000 to June 2005. All patients were hospitalized (N = 1,014) and met DSM-IV criteria for major depressive episode. Assessments with the 21-item Hamilton Depression Rating Scale were conducted biweekly until discharge. According to the most commonly applied exclusion criteria in randomized controlled antidepressant efficacy trials, patients were retrospectively divided into 2 groups: (1) patients not fulfilling exclusion criteria and therefore eligible for a randomized placebo-controlled trial, referred to as "efficacy sample," and (2) patients fulfilling at least 1 exclusion criterion, not being eligible for inclusion in an efficacy trial ("nonefficacy sample"). The efficacy sample was compared with the nonefficacy sample in terms of sociodemographic and clinical baseline variables and outcome measures, such as remission and response rates, 17-item Hamilton Depression Rating Scale mean scores, time to remission, and time to response. RESULTS Significant differences were found, with the efficacy sample being older (P = .03) and being more often treated at a university hospital (P = .02). The efficacy sample demonstrated superior outcome only in significantly higher mean Global Assessment of Functioning scores at discharge (P = .03). There were no differences regarding remission (P = .68) and response (P = .06) rates, length of hospital stay (P = .49), 17-item Hamilton Depression Rating Scale total score at discharge (P = .13), or time to response (P = .39) or remission (P = .16). CONCLUSIONS Both groups differed significantly in several baseline measures and final Global Assessment of Functioning scores but not in any other outcome measure. Challenging current beliefs, our findings show that results from efficacy antidepressant trials might be more generalizable than previously thought.

Abstract
INTRODUCTION Assessment of depression severity is of key importance, since several clinical guidelines recommend choice of treatment dependent on the depression severity grade. Using different tools to assess baseline severity may result in different outcomes. METHODS This paper describes the results of a multicentre, naturalistic study investigating the relationship between depression symptom severity (using 4 different measures of symptom severity) and clinical outcome among patients hospitalised for depression (N=1 014). Moreover, the impact of differences between methods of measuring depression severity has been investigated. Statistical analyses (univariate measurements, logistic regression models) were conducted to detect coherences and differences between the various methods of severity categorisation. RESULTS Results revealed different associations between outcome and classification methods. Response or remission rates varied if baseline severity was assessed by different instruments. Moreover, the number of responders increased with higher baseline severity grades of depression, whereas the number of remitters decreased. Additional analyses dependent on outcome criteria using continuous instead of categorical data revealed similar results. DISCUSSION Baseline severity may be only one of many other important clinical variables that mediate clinical outcome, but it is surely an important one deserving further research and consideration.

Abstract
BACKGROUND The aim of this paper is to apply the proposed consensus remission criteria to an acutely ill inpatient sample at admission and evaluate their adaptability in this patient population and pharmaceutical trials. METHODS The Remission in Schizophrenia Working Group's consensus criteria were applied to 272 acutely ill schizophrenia patients. Patients were examined using the PANSS, HAMD, UKU and SWN-K total scales at admission as well as the GAF, SOFAS and the Strauss-Carpenter Prognostic Scale. Sociodemographic and clinical baseline variables were assessed using a standardized documentation system. RESULTS 33 patients (12%) fulfilled the symptom severity component of the proposed remission criteria already at baseline. Almost no significant differences were found when comparing patients with achieved and failed symptom severity component that would explain the hospitalization of the patients with achieved criteria despite their apparently mild psychopathological symptoms. The only explainable difference was that patients with an achieved symptom severity component had received significantly more antipsychotics and had suffered from significantly more life events before admission. CONCLUSION The present results raise the question whether the symptom severity threshold is adequate to identify patients in remission when applied in clinical trials.

Abstract
In 2009 the WPA President established a Task Force that was to examine available evidence about the stigmatization of psychiatry and psychiatrists and to make recommendations about action that national psychiatric societies and psychiatrists as professionals could do to reduce or prevent the stigmatization of their discipline as well as to prevent its nefarious consequences. This paper presents a summary of the Task Force's findings and recommendations. The Task Force reviewed the literature concerning the image of psychiatry and psychiatrists in the media and the opinions about psychiatry and psychiatrists of the general public, of students of medicine, of health professionals other than psychiatrists and of persons with mental illness and their families. It also reviewed the evidence about the interventions that have been undertaken to combat stigma and consequent discrimination and made a series of recommendations to the national psychiatric societies and to individual psychiatrists. The Task Force laid emphasis on the formulation of best practices of psychiatry and their application in health services and on the revision of curricula for the training of health personnel. It also recommended that national psychiatric societies establish links with other professional associations, with organizations of patients and their relatives and with the media in order to approach the problems of stigma on a broad front. The Task Force also underlined the role that psychiatrists can play in the prevention of stigmatization of psychiatry, stressing the need to develop a respectful relationship with patients, to strictly observe ethical rules in the practice of psychiatry and to maintain professional competence.

Abstract
OBJECTIVES The present publication sets out to evaluate the position of psychopathology in the 21st century and should also serve as a basis for defining the framework for the future tasks of the WFSBP Task Force. METHODS Review of publications on the various approaches of psychopathology in general and of different tasks, theories and tools of psychopathology approaches in particular. RESULTS The main tasks of psychopathology are, to record and describe experiential and behavioral abnormalities in their intersubjective context, to explain their origin from an objective scientific perspective, and to attempt to understand them from the subjective perspective of the patient. In order to provide stable fundaments for the work in clinical and scientific psychiatry all three components are indispensable. CONCLUSIONS The future of psychiatry hence lies in the hands of a type of psychopathology that we will call Integrative Psychopathology. The main tasks of psychopathology can only be pursued in close cooperation with other branches of science interested in studying psychiatric issues. Whereas contemporary psychopathology must lay the foundations for that cooperation, Integrative Psychopathology must be complemented by further advancements in Theoretical Psychopathology, so as to enable conceptual new developments, which can then be fruitful for cooperative research and psychiatric clinical practice.

Abstract
OBJECTIVES To examine quality of life and subjective well-being as predictors of symptomatic treatment outcome. METHODS Biweekly PANSS ratings were performed in 285 inpatients with schizophrenia spectrum disorders within a multicenter trial by the German Research Network on Schizophrenia. Quality of life and subjective well-being were assessed using the Medical Outcomes Study-Short Form 36-Item Health Survey (SF-36), the Subjective Well-being Under Neuroleptic Treatment Scale (SWN-K) and the Adjective Mood Scale (AMS). Response was defined as an initial 20% PANSS total score reduction and remission according to the consensus criteria. Correlation analysis, logistic regression and CART-analysis were performed. RESULTS In total, 81% of the sample achieved symptom response and 48% symptom remission. The statistical analyses revealed early improvement within the first two treatment weeks in the SWN-K scale to be a significant predictor for symptomatic response. Concerning symptomatic remission the SF-36 and SWN-K baseline scores as well as SWN-K early improvement showed significant predictive value. CONCLUSIONS These results highlight the importance of the patient's self-perception and especially of early improvement of quality of life and subjective well-being for symptomatic treatment outcome.

Abstract
We performed an Internet-based questionnaire survey of the opinions of German-speaking psychiatrists regarding the experiences with the 10th revision of the international classification of mental disorders (chapter F of ICD-10). We received 304 completed questionnaires including more than 500 free-text comments. The responding group was characterized by professionally experienced middle-aged psychiatrists. German-speaking psychiatrists were comparatively content with ICD-10. Most diagnostic categories received a "satisfied" or "very satisfied" rating by the majority of respondents. Negative "goodness of fit" ratings--a possible indicator of the need for revision--were not higher than 50% for any category. Based on free-text entries, neurasthenia was the single diagnostic category most often suggested for deletion in ICD-11. Changes were considered necessary mainly for dementias and personality disorders. Adult attention deficit disorder and narcissistic personality disorder were the two diagnostic categories most frequently suggested to be added as new categories. This study provides valuable information related to perceived clinical utility of the classification, though with a narrow sample. Information about clinicians' experiences should be combined with scientific evidence for the revision process of ICD-11.

Abstract
BACKGROUND Early improvement with treatment is thought to be important in patients with first-episode schizophrenia, yet a valid definition is still outstanding. AIMS To develop a valid definition of early improvement and test its predictive validity regarding response and remission. METHOD We examined 188 in-patients with first-episode schizophrenia. Early improvement was defined as improvement in Positive and Negative Syndrome Scale (PANSS) total score at week 2, response as a 40% PANSS total score improvement at end-point, and remission according to consensus criteria. RESULTS Reasonable predictive validity of early improvement was found for a 46% PANSS total score improvement at week 2 and a 50% improvement for remission (area under the curve: response 0.707, remission 0.692). Estimated confidence intervals ranged from 26 to 62% PANSS reduction for response and remission. CONCLUSIONS Patients with a first episode of schizophrenia should improve by at least 30% in PANSS total score at week 2 to achieve response and remission.

Abstract
Sustained attention as measured by the Continuous Performance Test (CPT) has proved a valuable endophenotype for schizophrenia. Recently pharmacological studies suggested a role of the serotonin (5-HT) 3 receptor in schizophrenia. The 5-HT3 receptors are the only ligand-gated ion channels within the 5-HT receptor family. Applying an endophenotype approach, we investigated a potential impact of the genes of the 5-HT3A and 5-HT3B subunits as well as the novel 5-HT3C, 5-HT3D, and 5-HT3E subunits on CPT performance in subjects with schizophrenia. The study included 196 patients with schizophrenia, 113 of their parents, and 205 healthy controls recruited from community registers. Sustained attention was assessed with the Continuous Performance Test-Identical Pairs (CPT-IP). Assessing functional and coding variants of the 5-HT3 receptor subunit genes, we found the GG genotype of the 5-HT3E subunit gene (rs7627615; Thr86Ala) to be associated with better attentional capacities in subjects with schizophrenia and healthy controls. This study provides additional evidence for a role of the serotonergic system and the 5-HT3 receptor in schizophrenia.

Abstract
UNLABELLED We conducted a randomized, sham-controlled repetitive transcranial magnetic stimulation (rTMS) study in chronic schizophrenia in-patients (n=35) to evaluate the therapeutic efficacy of 10 Hz stimulation. Patients, who were on stable antipsychotic treatment, were randomly assigned to the active or sham condition. In the active rTMS group, ten sessions with a total of 10,000 stimuli were applied over the left dorsolateral prefrontal cortex at 110% of motor threshold. The sham group received corresponding sham stimulation. Clinical improvement was measured by the Clinical Global Impression scale (primary outcome measure), the Global Assessment of Functioning Scale (GAF) and the Positive and Negative Symptom Scale (PANSS; secondary outcome measures). Between-group comparisons revealed no significant differences in clinical outcome variables. Only a subgroup of patients with pronounced negative symptoms developed some clinical improvement as indicated by significant changes in the GAF-scale. Besides there is some evidence for a more favourable clinical outcome within this subgroup after rTMS in the CGI-S and PANSS negative scale, too. In line with earlier investigations, our results suggest a moderate - potentially clinically relevant - treatment effect of prefrontal 10 Hz rTMS stimulation in chronic patients. However, in our study this beneficial effect was restricted to subjects with pronounced negative symptoms.

Abstract
OBJECTIVE Purpose was to assess suicidality before and at the time of admission in patients with schizophrenia and compare outcome differences. METHOD Biweekly PANSS (Positive and Negative Syndrome Scale), HAMD (Hamilton Depression Rating Scale) and UKU (Udvalg for Klinske Undersogelser Side Effect Rating Scale) ratings were evaluated in 339 in-patients with schizophrenic spectrum disorders. Response was defined as an initial 20% PANSS total score reduction at discharge, remission was defined according to the proposed consensus criteria by the Remission in Schizophrenia Working Group. RESULTS Suicidal patients (22%) scored significantly higher on the PANSS negative subscore, PANSS insight item and HAMD total score at admission and at discharge. They developed significantly more side effects. No differences were found concerning response and remission between the two patient subgroups. CONCLUSION Despite receiving significantly more antidepressants the suicidal patients suffered from significantly more depressive symptoms up to discharge, yet without differing regarding response and remission.

Abstract
Due to strict exclusion criteria the generalizability of randomized controlled trials appears to be limited. Therefore, outcomes of naturalistically treated depressive inpatients with respect to depression mean scores, response and remission rates were evaluated. This was a multicenter trial, conducted in 12 psychiatric hospitals in Germany with a follow-up period of 4years. Patients were assessed biweekly from admission to discharge with diverse psychopathological rating scales. All patients (n=1014) met DSM-IV criteria for major depressive episode. Results are presented only for the acute inpatient treatment period. Mean inpatient treatment duration was 53.6+/-47.5days. Reduction on depression scales was evident as soon as week 2 and remained significant. Mean HAMD-17 total score decreased from 22.3 to 8.8. A total of 68.9% were classified as responders (> or =50% reduction of the initial HAMD-17 score), whereas 51.9% achieved remission (HAMD-17 total score < or =7). Of those who ultimately achieved response more than 40% did so within the first 2weeks. An individualized naturalistic inpatient treatment approach appears to be beneficial in terms of effectiveness.

Abstract
OBJECTIVE To describe the course of positive and negative symptoms during inpatient treatment and examine remission and response rates under routine clinical care conditions. METHODS Two hundred and eighty inpatients with schizophrenia (DSM-IV criteria) were assessed with the Positive and Negative Syndrome Scale (PANSS) at admission and at biweekly intervals until discharge from hospital. Remission was defined according to the symptom-severity component of the consensus criteria (Remission in Schizophrenia Working Group) as a rating of three or less in the relevant PANSS items at discharge, and response as a reduction of at least 20% in the PANSS total score from admission to discharge. RESULTS The mean duration of inpatient treatment was 54.8 days. Of the total sample, 78.5% achieved the criteria for response and 44.6% those for remission. Mean PANSS total scores decreased from 72.4 at admission to 52.5 at discharge (p<0.001). A reduction in PANSS total scores was found from visit to visit, up to week 8. The most pronounced decline was observed within the first two weeks of treatment. CONCLUSION Response rates were comparable to those found in efficacy studies, and remission rates were slightly higher. This may be explained by differences in the selection and the treatment of patients. Nevertheless, the findings might indicate that a complex naturalistic treatment approach is beneficial in terms of effectiveness.

Abstract
The genetic factors determining the progression of prodromal syndromes to first episode schizophrenia have remained enigmatic to date. In a unique prospective multicentre trial, we assessed whether variants at the D-amino acid oxidase activator (DAOA)/G72 locus influence progression to psychosis. Young subjects with a prodromal syndrome were observed prospectively for up to 2 years to assess the incidence of progression to schizophrenia or first episode psychosis. Of the 82 probands with a prodromal syndrome, 21 probands experienced progression to psychosis within the observation period. Assessment of nine common variants in the DAOA/G72 locus yielded two variants with the predictive value for symptom progression: all four probands with the rs1341402 CC genotype developed psychosis compared with 17 out of 78 probands with the TT or CT genotypes (chi(2) = 12.348; df = 2; p = 0.002). The relative risk for progression to psychosis was significantly increased in the CC genotype: RR = 4.588 (95% CI = 2.175-4.588). Similarly, for rs778294, 50% of probands with the AA genotype, but only 22% of probands with a GG or GA genotype progressed to psychosis (chi(2) = 7.027; df = 2; p = 0.030). Moreover, haplotype analysis revealed a susceptibility haplotype for progression to psychosis. This is one of the first studies to identify a specific genetic factor for the progression of prodromal syndromes to schizophrenia, and further underscores the importance of the DAOA/G72 gene for schizophrenia.

Abstract
OBJECTIVE Standardized consensus criteria for remission in schizophrenia were recently proposed. The present study applied the symptom-severity component of these criteria to a sample of inpatients in order to determine the rates of remission during inpatient treatment and to explore predictors of remission. METHOD A total of 288 inpatients from a multi-centre follow-up programme who fulfilled ICD-10 criteria for schizophrenia were included in the present analyses. PANSS ratings at admission and at discharge from hospitalization were used to examine remission status. Clinical and sociodemographic variables at admission were tested for their ability to predict remission at discharge. RESULTS In total, 55% of the sample achieved symptom remission during inpatient treatment; 84% percent showed remission with respect to 'reality distortion', 85% with respect to 'disorganization' and only 65% with respect to 'negative symptoms'. Logistic regression analysis revealed that the global functioning (GAF) in the year before admission, the total score of the Strauss-Carpenter Prognostic Scale and the PANSS negative subscore at admission were predictive for symptom remission. The regression model showed a predictive value of about 70% and explained 36% of the observed variance. CONCLUSION The results highlight the impact of negative symptoms for the course and treatment response of schizophrenic illness.

Abstract
INTRODUCTION The purpose of this study was to assess tolerability and safety of high-frequency rTMS with regard to cognitive performance when conducted as "add-on" treatment in chronic schizophrenia in-patients (n=32). METHODS Patients, who were on stable antipsychotic treatment, were randomly assigned to verum or sham condition (double-blind). In the verum group, ten sessions of 10 Hz rTMS with a total of 10 000 stimuli were applied over the left dorsolateral prefrontal cortex (PFC) at 110% of motor threshold over a period of two weeks. The sham group received corresponding sham stimulation. RTMS effects on cognitive performance were assessed with a neuropsychological test battery consisting of the following tests: trail making test A and B (TMT), Wisconsin card sorting test (WCST), D2 attention task and the "short test of general intelligence" (KAI). RESULTS No statistically significant deterioration of cognitive performance was observed as a result of rTMS treatment. Moreover it was shown that in the verum group patients with a less favourable performance on the WCST at baseline tend to improve after rTMS treatment with regard to psychopathology as opposed to patients in the control group. DISCUSSION The stability of cognitive function suggests good tolerability of rTMS treatment in schizophrenia. The absence of evidence for cognitive deterioration could be due to low and short stimulation parameters.

Abstract
OBJECTIVES Although schizophrenia affects both human genders, there are gender-dependent differences with respect to age of onset, clinical characteristics, course and prognosis of the disease. METHODS To investigate sex-dependent differences in motor coordination and activity as well as in cognitive and social behavior, we repeatedly tested female (n = 14) and male (n = 12) Fisher rats (postnatal days, PD 56-174) that had received intracerebroventricular injections of kainic acid as well as female (n = 15) and male (n = 16) control animals. The hippocampus was examined histologically. RESULTS Compared to male controls, in the alcove test both female controls and female animals with prenatal intervention spent less time in a dark box before entering an unknown illuminated area. Again, animals that received prenatal injection (particularly females) made more perseveration errors in the T-maze alternation task compared to controls. Female rats exhibited a higher degree of activity than males, suggesting these effects to be sex-dependent. Finally, animals that received prenatal intervention maintained longer lasting social contacts. Histological analyses showed pyramidal cells in the hippocampal area CA3 (in both hemispheres) of control animals to be longer than those found in treated animals. Sex-dependent differences were found in the left hippocampi of control animals and animals after prenatal intervention. CONCLUSION These results demonstrate important differences between males and females in terms of weight gain, response to fear, working memory and social behavior. We also found sex-dependent differences in the lengths of hippocampal neurons. Further studies on larger sample sets with more detailed analyses of morphological changes are required to confirm our data.

Abstract
Schizophrenia clinical practice guidelines are developed to provide expert- and evidence-based advice to practicing psychiatrists in order to improve the management of this disorder. However, the application of these guidelines in everyday health care can still be described as nonsatisfying. Within the project "Guideline-supported quality management in outpatient treatment", we investigated whether guideline adherence and quality of outcome can be improved by implementing a computer-based, guideline-oriented decision-support system. Therefore, a disease-specific decision-support system was developed interactively presenting guidelines to support the physicians decision-making process during the treatment of schizophrenia patients. We evaluated the system in a control group design: An experimental group consisting of 15 psychiatrists in private practice used the decision-support system, thus documenting the treatment of schizophrenic patients. Guideline-based algorithms were interactively and case specifically displayed on the PC-screen as soon as predefined triggers were met. A first control group in Munich provided treatment-as-usual, documenting the treatment via paper-pencil. Two further physician groups served as additional comparison groups: one also documented electronically using the decision-support system, however without receiving electronic guideline support, the second group carried out traditional quality circles while also using the paper-pencil approach. As a result of the intervention, we observed a strong initial but time-limited improvement with respect to the core aspects of outpatient treatment in schizophrenia in the experimental group. The findings suggest that decision-support systems, despite their limitations, can be used to enhance treatment outcome in schizophrenia outpatient care.

Abstract
OBJECTIVES The aim of our study was to investigate the impact of typical and atypical antipsychotic drugs on leptin concentration in blood and changes in the receptor expression in the hypothalamus of male Wistar rats. METHODS From the age of 13 to 18 weeks, three groups of 20 animals were fed an average dose of 3.5 + 0.03 mg/ kg body weight (BW) haloperidol; 30.6 + 0.22 mg/kg BW clozapine; or 14.9 + 0.13 mg/kg BW ziprasidone in ground food pellets containing 15% fat. Twenty control animals received no drugs. Blood samples were taken at week 14, 16, and 19. Locomotor activity and exploratory behavior were measured using the alcove test at weeks 15 and 17. The expression of the hypothalamic leptin receptor in rat brains was determined by using a Western blot. RESULTS Rats medicated with haloperidol and ziprasidone showed a significantly decreased percentage weight gain and food consumption. We observed no differences in the alcove test, but locomotor activity was significantly reduced in the haloperidol group. Except for rats in the clozapine and ziprasidone groups, after 2 weeks of drug application, we found no changes in the leptin blood concentrations among the four groups or animals within each group. Moreover, we did not find specific differences in hypothalamic leptin receptor expression among the groups. CONCLUSION We concluded that in male Wistar rats during this treatment period, the tested drugs did not act directly on the leptin regulatory system. We recommend further studies using long-term treatment of different rat strains.

Abstract
BACKGROUND Purpose of the present study was to assess the attitude towards adherence at discharge and to verify its predictability using anamnestic and sociodemographic variables, factors influencing clinical treatment as well as the medical treatment applied. METHODS Attitude towards adherence was evaluated in 369 inpatients with schizophrenic spectrum disorders within a naturalistic multicenter trial using the Compliance Rating Scale (CRS) by Kemp. Biweekly ratings of the PANSS, UKU and the Subjective Well-being under Neuroleptic Treatment Scale (SWN-K) were applied. Logistic regression and CART analyses were used to determine significant predictor variables for the attitude towards adherence at discharge. RESULTS Sixty-seven percent of the patients were rated to have an attitude of active participation and moderate participation (=positive attitude towards adherence) and 33% of the patients to have an attitude of passive acceptance, occasional or permanent reluctance towards treatment as well as refusing treatment (=negative attitude towards adherence). A significant correlation was found between patients with a positive attitude towards adherence and course of all PANSS subscales. Statistical analyses revealed a reduction in PANSS general psychopathology subscore, employment status, greater illness insight and treatment with atypical antipsychotics to be significantly predictive for a positive attitude towards adherence at discharge. CONCLUSIONS The importance of an adequate antipsychotic treatment as a precondition for a favourable adherence attitude and the need to incorporate adherence-focused psychotherapy and psychoeducation into daily clinical practice are highlighted.

Abstract
BACKGROUND Blunting of prolactin response after serotonergic stimulation during a major depressive episode has been described by several investigators. In this study, the neuroendocrine responses to clomipramine were assessed in remitted patients suffering from hereditary depression. METHODS Twenty remitted patients from 11 large families with multigenerational, multiple cases of major affective disorder (bipolar disorder n=15, recurrent depression n=5, according DSM-IV) and 12 healthy relatives were investigated. After intravenous application of 12.5 mg of the serotonin re-uptake inhibitor clomipramine, serum prolactin and cortisol levels were analysed. RESULTS Patients and comparison group did not differ significantly with respect to age, baseline prolactin and cortisol concentrations. A gender effect was found in an exploratory analysis for prolactin but not for cortisol and therefore the data for prolactin were analysed separately. After clomipramine infusion, the increase of cortisol was significantly lower in patients than in the comparison group (P=.046). For prolactin, this effect could be found in the male (P=.012) as well as in the female (P=.007) subsample. CONCLUSIONS These results suggest that blunted prolactin and cortisol responses to serotonergic stimulation are characteristic for remitted depressive patients with previous episodes of major affective disorders.

Abstract
In many occasions, routine mental health care does not correspond to the standards that the medical profession itself puts forward. Hope exists to improve the outcome of severe mental illness by improving the quality of mental health care and by implementing evidence-based consensus guidelines. Adherence to guideline recommendations should reduce costly complications and unnecessary procedures. To measure the quality of mental health care and disease outcome reliably and validly, quality indicators have to be available. These indicators of process and outcome quality should be easily measurable with routine data, should have a strong evidence base, and should be able to describe quality aspects across all sectors over the whole disease course. Measurement-based quality improvement will not be successful when it results in overwhelming documentation reducing the time for clinicians for active treatment interventions. To overcome difficulties in the implementation guidelines and to reduce guideline non-adherence, guideline implementation and quality assurance should be embedded in a complex programme consisting of multifaceted interventions using specific psychological methods for implementation, consultation by experts, and reimbursement of documentation efforts. There are a number of challenges to select appropriate quality indicators in order to allow a fair comparison across different approaches of care. Carefully used, the use of quality indicators and improved guideline adherence can address suboptimal clinical outcomes, reduce practice variations, and narrow the gap between optimal and routine care.
