Abstract
Objective This study was performed to investigate the efficacy and tolerability of blonanserin in schizophrenic patients who were previously treated with other antipsychotics but, due to insufficient response, were switched to blonanserin. Methods A total of 52 patients with schizophrenia who were unresponsive to treatment with antipsychotic monotherapy or combination therapy were recruited into this 12-week, open-label, prospective, multicenter study. Patients were switched to blonanserin from their existing antipsychotics over a maximum 2-week tapering-off period. Efficacy was primarily evaluated using the 18-item Brief Psychiatric Rating Scale (BPRS). Assessments were performed at baseline, and at weeks 1, 2, 4, 8, and 12. Results Switching to blonanserin resulted in a significant decrease in the mean total score on the BPRS from baseline (56.8 ± 9.4) to week 12 (42.1 ± 13.8, p < 0.001). The most common adverse events were extrapyramidal symptoms (n = 12, 23.1%), insomnia (n = 10, 19.2%), and emotional arousal (n = 6, 11.5%). Overweight or obese patients (body mass index ≥ 23 kg/m2, n = 33) who switched to blonanserin exhibited significant weight loss from 75.2 ± 9.3 kg at baseline to 73.5 ± 9.2 kg at week 12 (p = 0.006). The total cholesterol (baseline, 236.1 ± 47.6 mg/dl; endpoint [week 12], 209.9 ± 28.0 mg/dl; p = 0.005) and prolactin levels (baseline, 80.0 ± 85.2 ng/ml; endpoint [week 12], 63.2 ± 88.9 ng/ml; p = 0.003) were also significantly improved in patients with hypercholesterolemia or hyperprolactinemia. Conclusion The results of the present study suggest that switching to blonanserin may be an effective strategy for schizophrenic patients unresponsive to other antipsychotic treatments.

Abstract
OBJECTIVE The aim of the present study was to investigate differences in discontinuation time among antidepressants and total antidepressant discontinuation rate of patients with depression over a 6 month period in a naturalistic treatment setting. METHODS We reviewed the medical records of 900 patients with major depressive disorder who were initially prescribed only one kind of antidepressant. The prescribed antidepressants and the reasons for discontinuation were surveyed at baseline and every 4 weeks during the 24 week study. We investigated the discontinuation rate and the mean time to discontinuation among six antidepressants groups. RESULTS Mean and median overall discontinuation times were 13.8 and 12 weeks, respectively. Sertraline and escitalopram had longer discontinuation times than that of fluoxetine, and patients who used sertraline discontinued use significantly later than those taking mirtazapine. No differences in discontinuation rate were observed after 24 weeks among these antidepressants. About 73% of patients discontinued antidepressant treatment after 24 weeks. CONCLUSION Sertraline and escitalopram tended to have longer mean times to discontinuation, although no difference in discontinuation rate was detected between antidepressants after 24 weeks. About three-quarters of patients discontinued antidepressant maintenance therapy after 24 weeks.

Abstract
OBJECTIVE This study aimed to evaluate the subjective well-being and attitudes toward antipsychotic medication of patients with schizophrenia who had switched to paliperidone extended release (ER). METHODS A total of 291 patients with schizophrenia treated with antipsychotics participated in this open-label, 24-week switching study. The primary outcome measures were the Subjective Well-Being under Neuroleptic Treatment Scale-short version (SWN-K) and the Drug Attitude Inventory (DAI). The Krawiecka scale, Clinical Global Impression-Schizophrenia (CGI-SCH), Personal and Social Performance scale (PSP) were used to evaluate psychopathology and psychosocial functioning, respectively. RESULTS Data from a total of 243 subjects who received the study medication and had at least one follow-up assessment without a major protocol violation were analyzed. Scores on the DAI and SWN-K showed significant improvement between baseline and end-point measurements beginning during the second week. Scores on the Krawiecka scale, all five subscales of the CGI-SCH scale, and the PSP scale were also significantly improved at the end point compared with the baseline. Significant predictors of improvements in the SWN-K and DAI after a switch to paliperidone ER were baseline scores, reductions in scores on the Krawiecka scale, and previous risperidone use. A clinically relevant increase in body weight (≥7% weight gain) occurred in one-fourth of the participants who completed the 24-week study. CONCLUSION Switching to paliperidone ER improved the subjective well-being and attitudes towards antipsychotic medication in patients with schizophrenia. Exploratory analyses revealed that these improvements were particularly pronounced in patients who had been treated with risperidone before treatment with paliperidone ER.

Abstract
OBJECTIVE This study analyzed the symptom frequencies of 17-item Hamilton Depression Rating Scale (HDRS-17) to understand the characteristics of each item and to propose the possible symptoms clusters. METHODS From psychiatric clinics of 18 Hospitals in Korea, 1,183 patients, diagnosed with major depressive disorder (psychotic or non-psychotic), dysthymia or depressive disorder not otherwise specified. according to DSM-IV criteria, participated in this study from January 2006 to August 2008. The frequencies of each item of HDRS-17 were analyzed according to sex and severity. In addition, we compared this study with a previous study performed in England by Hamilton and with two studies performed in Korea by Kim et al. RESULTS The frequencies of HDRS-17 items varied widely in this study, ranging from 95.8% in work and activities to 37.4% in loss of weight. But, depressed mood, psychic anxiety and work and activities items exhibited constant and higher frequency or rank regardless of study, the severity of depression or sex. Insomnia early, somatic gastrointestinal, genital symptoms and insight showed relatively constant but lower frequency or rank in disregard of studies or the clinical variables. Other symptoms had variable frequencies or ranks according to the variable clinical situations (culture, time, sex, severity of depression). CONCLUSION WE PROPOSE THREE CLUSTERS OF SYMPTOMS IN DEPRESSIVE DISORDERS: core symptoms cluster, an associated symptoms, and a situation-specific symptoms. We can use these possible symptom clusters of depression in simplifying diagnosis of depression, increasing diagnostic specificity in special situation and indexing disease severity.
