    OBJECTIVE: This randomized, double-blind study evaluates the efficacy and tolerability of agomelatine, using fluoxetine as an active comparator, in Asian patients suffering from moderate to severe major depressive disorder (MDD).
    METHOD: Patients were randomly assigned to receive either agomelatine (25-50mg/day, n=314) or fluoxetine (20-40mg/day, n=314) during an 8-week treatment period. The main outcome measure was the change in Hamilton Depression Rating Scale 17 items (HAM-D17) scores. Secondary efficacy criteria included scores on Clinical Global Impression Severity of illness (CGI-S) and Improvement of illness (CGI-I), patient sleeping improvement using the self-rating Leeds Sleep Evaluation Questionnaire (LSEQ) and anxiety using the Hamilton Anxiety Rating Scale (HAM-A) scores. Tolerability and safety evaluations were based on emergent adverse events.
    RESULTS: Agomelatine and fluoxetine exert a comparable antidepressant efficacy in the Asian population. Mean changes over 8 weeks were clinically relevant and similar in both groups (-14.8±7.3 and -15.0±8.1 on HAM-D17 scale in agomelatine and fluoxetine groups, respectively). The between-group difference reached statistical significance on non-inferiority test (p=0.015). Clinically relevant decreases in CGI-S and CGI-I scores were observed over the treatment period in both groups. The two treatments were equally effective on the symptoms of both anxiety and sleep. The good tolerability profile and safety of both doses of agomelatine was confirmed in the Asian population.
    CONCLUSIONS: Agomelatine and fluoxetine are equally effective in the treatment of MDD-associated symptoms in Asian depressed patients.

    Attention Deficit Hyperactivity Disorder (ADHD) is a clinical diagnosis relying on persistence of symptoms across different settings. Information are gathered from different informants including adolescents, parents and teachers. In this cross-sectional study involving 410 twelve-year old adolescents, 37 teachers and 367 parents from seven schools in the Federal Territory of Kuala Lumpur, reliability of ADHD symptoms among the various informants were reported. ADHD symptoms (i.e. predominantly hyperactive, predominantly inattentive and combined symptoms) were assessed by adolescents, teachers and parents, using Conners-Wells' Adolescent Self-report Scale (CASS), Conner's Teachers Rating Scale (CTRS) and Conner's Parents Rating Scale (CPRS) respectively. For predominantly hyperactive symptoms, there were statistically significant, weak positive correlations between parents and teachers reporting (r=0.241, p<0.01). Statistically significant, weak positive correlations were found between adolescents and parents for predominantly inattentive symptoms (r=0.283, p<0.01). Correlations between adolescents and parents reporting were statistically significant but weak (r=0.294, p<0.01). Weak correlations exist between the different informants reporting ADHD symptoms among Malaysian adolescents. While multiple informant ratings are required to facilitate the diagnosis of ADHD, effort should be taken to minimize the disagreement in reporting and better utilize the information.

    This study evaluated the convergent, discriminant, construct, concurrent and discriminative validity of the Medical Student Wellbeing Index (MSWBI) as well as to evaluate its internal consistency and optimal cut-off total scores to detect at least moderate levels of general psychological distress, stress, anxiety and depression symptoms. A cross sectional study was done on 171 medical students. The MSWBI and DASS-21 were administered and returned immediately upon completion. Confirmatory factor analysis, reliability analysis, ROC analysis and Pearson correlation test were applied to assess psychometric properties of the MSWBI. A total of 168 (98.2%) medical students responded. The goodness of fit indices showed the MSWBI had a good construct (χ(2)=6.14, p=0.803, RMSEA<0.001, RMR=0.004, GFI=0.99, AGFI=0.97, CFI=1.00, IFI=1.02, TLI=1.04). The Cronbach's alpha value was 0.69 indicating an acceptable level of internal consistency. Pearson correlation coefficients and ROC analysis suggested each MSWBI's item showed adequate convergent and discriminant validity. Its optimal cut-off scores to detect at least moderate levels of general psychological distress, stress, anxiety, and depression were 1.5, 2.5, 1.5 and 2.5 respectively with sensitivity and specificity ranged from 62 to 80% and the areas under ROC curve ranged from 0.71 to 0.83. This study showed that the MSWBI had good level of psychometric properties. The MSWBI score more than 2 can be considered as having significant psychological distress. The MSWBI is a valid and reliable screening instrument to assess psychological distress of medical students.

    Many studies have reported that the prevalence of psychological distress among medical students during medical training was high. However, there are very few studies exploring on the psychological health of prospective medical students. This study aimed to determine the prevalence and associated factors for stress, anxiety and depression symptoms among the prospective medical students. A cross-sectional study was done on two cohorts of applicants to a public medical school. A total of 839 applicants were invited to participate in the study. The 21-item Depression Anxiety Stress Scale was administered to the applicants after they completed interviews. A total of 743 (92.2%) applicants took part in the study. The prevalence of moderate to extremely severe level of stress, anxiety and depression were 3.6%, 54.5% and 1.9%, respectively. Stress was significantly associated with extra-curricular activity (p<0.001) and race (p<0.001). Anxiety was associated with extra-curricular activity (p<0.001), race (p<0.001), mother education level (p=0.002) and CGPA group (p=0.034). Depression was associated with academic performance in class (p<0.001) and race (p=0.004). Prevalence of stress and depression among entering medical students was low; however prevalence of anxiety was high which could be due to worry about the interviews to enter medical course. The associated factors of psychological distress among prospective medical students were related to academic, non-academic, parent education and cultural backgrounds.

    Depression and insomnia are common psychiatric disorders among elderly people and reported to be related to several social and health factors. However, their occurrences in relation to food intake have rarely been investigated. Therefore, this study was to identify determinants of depression and insomnia, with emphasised on food intake among 71 elderly people residing in a government funded institution in Malaysia. An interview based questionnaire was used to obtain information on socio-demography, health and functional status, depression, insomnia and food intake. A total of 71.8% subjects had depression and 53% had insomnia. Subjects who had insomnia [Adjusted Odds Ratio (AOR) 19.55, 95% CI=4.04-94.64], needed help/unable to perform >4 items of IADL (AOR=16.65, 95% CI=3.95-70.22), had hypertension (AOR=7.66, 95% CI=1.37-42.76), had >50% wastage of poultry or fish (AOR=3.66, 95% CI=1.06-12.60) and wastage of vegetables (AOR 3.31, 95% CI=1.03-10.60) were more likely to have depression. Subjects who had depression (AOR 19.55, 95% CI=4.04-94.64), needed help/unable to perform >4 items of IADL (AOR 2.97, 95% CI=1.12-7.84), needed help/unable to handle financial matters (AOR 5.01, 95% CI=1.37-18.27) and had >50% wastage of vegetables (AOR 3.91, 95% CI=1.42-10.82) were at a higher risk to develop insomnia. Depression and insomnia affected more than half of the subjects, interrelated, and associated with functional inability, socioeconomic factor and high food wastage of specific foods.

    The study compared knowledge and beliefs about depression among urban and rural Chinese in a Malaysian sample. A total of 409 participants were asked to identify cases of depression varying in intensity from two vignettes and rate their beliefs regarding a list of possible causes and treatments for depression. The urban Chinese were more likely to identify depression as the problem in the vignette. Beliefs about causes of depression were factored into five components, whereas beliefs about treatment for depression factored into four components. The results indicated that the causes most strongly endorsed were stress and pressure, and standard treatments rated the highest as treatments for depression. Overall, depression literacy was moderate for Chinese Malaysians. The results are discussed in relation to Chinese cultural beliefs about depression. Limitations of this preliminary study were acknowledged.

    HIV-associated neurocognitive disorder incurs a significant burden on HIV patients in Asia-Pacific countries; however, the incidence is difficult to estimate due to a lack of local epidemiological data. The impact of neurocognitive impairment in HIV patients is often underestimated due to a lack of education and awareness, and there are consequently gaps in the provision of screening and diagnosis to enable earlier intervention to limit neurocognitive impairment.

    Studies addressing the nature of relationship between psychological symptoms and quality of life among dialysis patients in Malaysia are scarce. Hence, this study is intended to investigate the association between psychological symptoms such as depression, anxiety and stress on the quality of life in dialysis patients. A cross sectional multicentre study was conducted from May to October 2012 at 15 centres that provide haemodialysis and/or peritoneal dialysis. Apart from socio-demographic profile data collection, WHOQOL-BREF and DASS21 questionnaires were administered to study subjects. All three psychological symptoms had significant impact on quality of life domains of physical health, psychological health, social impact, perceived environment and overall quality of life. These findings suggest that subjects with symptoms of depression, anxiety and stress had poorer quality of life than those without, highlighting the negative impact of psychological symptoms.

    Cambodia had suffered enormously due to war and internecine conflict during the latter half of the twentieth century, more so during the Vietnam War. Total collapse of education and health systems during the Pol Pot era continues to be a challenge for developing the necessary infrastructure and human resources to provide basic minimum mental health care which is compounded by the prevailing cultural belief and stigma over mental, neurological and substance abuse disorders (MNSDs). The mental health research and services in Cambodia had been predominantly 'trauma focused', a legacy of war, and there is a need to move toward epidemiologically sound public health oriented mental health policy and service development. Integrating mental health program with primary health care services with specifically stated minimum package of activities at primary level and complementary package of activities at secondary level is an opportunity to meet the needs and rights of persons with mental, neurological and substance abuse disorders (PWMNSDs) in Cambodia, provided there is mental health leadership, government commitment and political will.
