Objective: The co-prescription of multiple antipsychotic drugs continues to increase despite a lack of evidence supporting this practice. The purpose of this study was to quantify and describe recent trends of antipsychotic polypharmacy in Korean schizophrenic inpatients by comparing prescribed medications between the years of 2005 and 2010.Methods: We reviewed comprehensive medication profiles of schizophrenic patients discharged from a university psy-chiatric hospital in 2005 (n=194) or 2010 (n=201). Antipsychotic polypharmacy was defined as the concurrent receipt of two or more chemically distinct antipsychotics for at least 14 days. High antipsychotic dose was defined as a prescribed daily dose to defined daily dose ratio of greater than 1.5.Results: Antipsychotic polypharmacy increased between 2005 (37.1%) and 2010 (48.3%, p=0.025). The most frequently used drug within combinations of antipsychotics was haloperidol in 2005 (51.4%) and quetiapine in 2010 (48.5%). Over-all, no changes were observed between 2005 and 2010 in the rate of prescribing high-dose antipsychotics. High-dose antipsychotic monotherapy decreased across years (from 30.4 to 18.4%), but high-dose antipsychotic polypharmacy increased (from 34.0 to 45.3%). Regression analysis revealed that antipsychotic polypharmacy was strongly associated with high doses of prescribed antipsychotics (odds ratio=18.60, p<0.001).Conclusions: The practice of prescribing multiple antipsychotics to patients with schizophrenia is increasing, and high-dose antipsychotic drugs are more likely to be prescribed in combination than in isolation. The reasons for this pattern of prescription and its impact warrants further study. [ABSTRACT FROM AUTHOR]

Background: Cranial Electrotherapy Stimulation (CES) is a promising non-invasive brain stimulation technique with the potential to alleviate anxiety. We examined the effectiveness of home-based CES with novel, headphone-like, in-ear electrodes on anxiety-related symptoms and resting-state brain activity.Methods: This study spanned 3-weeks, with randomized, double blind, and active-controlled design. Nonclinical volunteers experiencing daily anxiety were randomly assigned to either the active or the sham groups. CES provides an alternating current (10 Hz frequency, 500 μA intensity), connected to smartphone recording treatment logs. Participants treated themselves with 20 trials of CES at home. We evaluated the effectiveness using State-Trait Anxiety Inventory (STAI), Beck Depression Inventory (BDI), Wisconsin Card Sort Test (WCST), and resting-state electroencephalography (EEG).Results: The active group showed a significant improvement in state-anxiety compared to sham, while there was a statistical trend in the WCST-Category Completed (p = .061) and no change in depression. In EEG analysis, the active group showed significantly increased relative power for theta in the left frontal region compared with the sham, and this significantly correlated with the changes in state-anxiety. The active group exhibited significantly increased high-beta source activity in cuneus and middle occipital gyrus after intervention compared with the baseline.Limitations: This study had a relatively short treatment period and small sample size.Conclusions: Our findings provide the first electrophysiological evidence for CES for novel in-ear electrodes to improve anxiety. The modulatory effects of CES on resting-state oscillations of EEG imply that CES could beneficially affect functional brain activity. [ABSTRACT FROM AUTHOR]

The objective of this study was to examine the feasibility and sustained effect of a group aerobic exercise program in patients with schizophrenia. Twenty-four schizophrenic patients participated in a group-based individually tailored 90-minute outdoor cycling session per week for 3 months with intervention to enhance motivation. Physical health was evaluated by anthropometric measures, cardiorespiratory (CR) fitness, and blood tests. Mental health was assessed on self-esteem, interpersonal relationship, quality of life, and global function. Attrition rate for the exercise program was 8.3%. Exercise program significantly increased participant's self-esteem, positive relationship, global function, and quality of life. CR fitness significantly improved after 3 months. At the 9-month follow-up, 6 months after program completion, only in interpersonal relationship change the improved effects were maintained. These findings support the feasibility of group aerobic exercise program with high level of adherence and its long-term benefits in positive relationship change. [ABSTRACT FROM AUTHOR]
