This study has contributed significantly in relation to the changing patterns of antidepressant use in all the participating Asian centers in the last 10 years. The findings are important in shaping optimal antidepressant prescription and future policy making.

<b><i>Introduction:</i></b> Depressive disorders are the 4th leading cause of health problems and the 2nd leading cause of burden among all diseases. Almost all depressive disorder patients have cognitive impairments to a certain extend. Studies about cognitive impairments in depression had been conducted, but whether cognitive dysfunctions are the cause or the effect is still not clear. <b><i>Objectives:</i></b> To analyze the process of working memory and cognitive flexibility impairments in a rat model of depression. <b><i>Methods:</i></b> In this experimental study, chronic unpredictable mild stress (CUMS) was used as a model of depression in 30 rats (<i>Rattus novergicus</i>). Cognitive function was assessed with the <i>Morris water maze</i> and <i>attentional set shifting test</i>. <b><i>Results:</i></b> This study found a significant difference on day 21 in working memory (<i>p</i> = 0.002) and cognitive flexibility (<i>p</i> = 0.036), which continued to day 41 in working memory (<i>p</i> = 0.001) and cognitive flexibility (<i>p</i> = 0.020). In the CUMS model of depression, parameters peak on day 41 and reveal parameter changes in weight gain (<i>p</i> = 0.018), food intake (<i>p</i> &#x3c; 0.001), changes in food intake (<i>p</i> = 0.001), and the sucrose preference (<i>p</i> = 0.005), elevated plus maze (<i>p</i> = 0.001), and light dark box tests (<i>p</i> = 0.020). <b><i>Conclusion:</i></b> In a rat model of depression, cognitive impairment preceded depression, but it might be caused by anxiety-like behavior that occurred in early stimulation of chronic unpredictable mild stress.

Introduction: Mental health problems, such as anxiety, depression, and ineffective family coping, in children with lupus nephritis (LN) can increase the severity and affect the management of the disease, thus affecting the quality of life (QoL) of patients. Objective: Analyzing the association between levels of depression, anxiety, coping, disease activity on the QoL of pediatric patients with LN. Patients and Methods: There were 62 pediatric LN participants (16 participants in the induction phase and 46 participants in the maintenance phase). Participants were measured for anxiety, depression, coping, disease activity (systemic lupus erythematosus disease activity index/SLEDAI), and QoL. The measurement results were compared between induction and maintenance groups. Analysis of the association between anxiety, depression, coping, and disease activity with the QoL of children with LN used a multiple logistic regression test with p <0.05. Results:: The measurement results obtained anxiety (induction = 69.06±3.92 and maintenance = 45.24±10.33; p <0.001), depression (induction = 69.88±3.34 and maintenance = 42.20±9.12; p <0.001), coping (induction = 99.88±12.93 and maintenance = 115.67±7.34; p <0.001), SLEDAI (induction = 15.81±12.58 and maintenance = 0.43±1.26; p <0.001), and QoL (induction = 49.92 ±12.44 and maintenance = 88.15±8.06; p <0.001).. Anxiety level in the induction group (p = 0.043) and maintenance group (p <0.001; p = 0.032; p = 0.008; p = 0.009). Depression level in the induction group (p = 0.031) and maintenance group (p = 0.024; p = 0.042; p = 0.003). SLEDAI score in the maintenance group (p = 0.003; p = 0.003). Coping in induction group (p = 0.016; p = 0.016) and maintenance group (p = 0.005). Conclusion: Mental health disorders reduce the QoL of LN children, and the level of QoL in induction phase is lower than maintenance phase.

This study demonstrates that in Asia, despite variations in the initial symptom reported by the patients, across different countries/territories, core depressive symptoms remain the same. Variations have been found in presentation of depressive symptoms with regards to the level of income of countries. Physical or vegetative symptoms were reported more by centers in higher income countries, while depressive cognition and suicidal thoughts/acts were more frequently reported from lower income countries.

Suicidal thoughts/acts can indicate greater severity of depression, and are associated with a poorer response to antidepressants and increased burden of illness. Hence, suicidal thoughts/acts can provide a clinical index reflecting the clinical status of depressive disorders in Asians.

Objective: Pharmacotherapy including mood stabilizers and antipsychotics are frequently used in bipolar disorder (BD); however, the lack of consensus regarding the definition of polypharmacy hinders conducting comparative studies across different settings and countries. Research on Asian Prescription Pattern (REAP) is the largest and the longest lasting international collaborative research in psychiatry in Asia. The objective of REAP BD was to investigate the prescription patterns of psychotropic medications across Asian countries. The rates of polypharmacy and psychotropic drug load were also analyzed. Methods: The data collection was web-based. Prescription patterns were categorized as (1) mood stabilizer monotherapy: one mood stabilizer; (2) antipsychotic monotherapy: one antipsychotic; (3) simple polypharmacy: one mood stabilizer and one antipsychotic; and (4) complex polypharmacy: ≥ 2 mood stabilizers or/and antipsychotics. The psychotropic drug load in each patient was calculated using the defined daily dose method. Results: Among 2003 patients with BD (52.1% female, 42.4 years) from 12 countries, 1,619 (80.8%) patients received mood stabilizers, 1,644 (82.14%) received antipsychotics, and 424 (21.2%) received antidepressants, with 14.7% mood stabilizer monotherapy, 13.4% antipsychotic monotherapy, 48.9% simple polypharmacy, 20.3% complex polypharmacy, and 2.6% other therapy. The average psychotropic drug load was 2.05 ± 1.40. Results varied widely between countries. 62 S.K. Lin, et al.Conclusion: Over 70% of psychotropic regimens involved polypharmacy, which accords with the high prevalence of polypharmacy in BD under a permissive criterion (2 or more core psychotropic drugs) worldwide. Notably, ≥ 80% of our sample received antipsychotics, which may indicate an increasing trend in antipsychotic use for BD treatment.
