INTRODUCTION: Depression is one of the most common psychiatric conditions in men. The aim of the study was to determine the depressive symptoms and associated factors among men on methadone maintenance therapy (MMT).
METHODS: A cross-sectional study was conducted involving 108 subjects who attended the Drug Clinic at Hospital Kuala Lumpur. The instruments used include the Structured Clinical Interview for Diagnostic and Statistical Manual, Fourth Edition Axis-I Disorder, Beck Depression Inventory and the 15-item International Index of Erectile Function.
RESULTS: The rate of depression was 44.4%. There were significant associations between Malay ethnicity, secondary education level and concurrent illicit cannabis use with depression (P
Decreased libido is recognized as one of the vegetative symptoms of depression. Increased libido has not been acknowledged as one of its symptoms, neither has it been reported, particularly in depressed bipolar patients.
The concept of a sexual response cycle (SRC) for women has gained interest lately with the reintroduction of terms with new definitions and a new model for the sexual response, especially the Basson's circular model.
Objective: To investigate the correlation between sexual desire and sexual arousal among Malaysian women in a primary care setting. Methods: The Malay Version of Female Sexual Function Index (MVFSI) was used to assess low sexual desire and lack of sexual arousal among the respondents. A total of 230 married women aged 18 – 70 years old participated in this study. Their sociodemographic, marital profiles and correlation between low sexual desire and lack of sexual arousal were examined. Results: More than 60% respondents with low sexual desire have co-exist low sexual arousal and 94.4% respondents with high sexual desire do have high sexual arousal ( χ²= 79.6, p
One of the potentials of carrier-free cross-linked enzyme aggregates (CLEA) immobilization is the ability to be separated and reuse. Yet, it might be impeded by the poor mechanical stability resulting low recyclability. CLEA of CGTase from Bacillus lehensis G1 (CGTase G1-CLEA) using chitosan (CS) as a cross-linker demonstrated high activity recovery however, displayed poor reusability. Therefore, the relationship between mechanical strength and reusability is studied by enhancing the CS mechanical properties and applying a new co-aggregation approach. Herein, CS was chemically cross-linked with glutaraldehyde (GA) and GA was introduced as a co-aggregant (coGA). CGTase G1-CLEA developed using an improved synthesized chitosan-glutaraldehyde (CSGA) cross-linker and a new coGA technique showed to increase its mechanical stability which retained 63.4% and 52.2%, respectively compared to using CS that remained 33.1% of their initial activity after stirred at 500 rpm. The addition of GA impacted the morphology and interaction consequently stabilizing the CLEAs durability in production of cyclodextrins. As a result, the reusability of CGTase G1-CLEA with CSGA and coGA increased by 56.6% and 42.8%, respectively compared to previous CLEA after 5 cycles for 2 h of reaction. This verifies that the mechanical strength of immobilized enzyme influences the improvement of its operational stability.
The objective of this study was to examine the risk of female sexual orgasmic disorder among a group of women with hypertension in Malaysia. The associated factors were also examined.
This cross-sectional study aimed to determine the construct of the phases of the female sexual response cycle (SRC) among women attending an infertility clinic in a Malaysian tertiary center.
SSRIs are known for their sexual side-effects with a variable rate of sexual dysfunction (SD). 5HT2A (rs6311) single nucleotide polymorphism (SNP) was found to have significant association with SD. The purpose of this study was to determine the prevalence of female SDD, its clinical correlates and association with 5HT2A (rs6311) SNP in patients with major depressive disorder (MDD) treated with SSRIs.
INTRODUCTION: To determine sociodemographic and psychological factors associated with bullying behavior among young adolescents in Malaysia.
METHODS: This is a cross-sectional study of four hundred ten 12-year-old adolescents from seven randomly sampled schools in the Federal Territory of Kuala Lumpur, Malaysia. Sociodemographic features of the adolescents and their parents, bullying behavior (Malaysian Bullying Questionnaire), ADHD symptoms (Conners Rating Scales), and internalizing and externalizing behavior (Child Behaviour Checklist) were obtained from adolescents, parents and teachers, respectively.
RESULTS: Only male gender (OR=7.071, p=0.01*, CI=1.642-30.446) was a significant sociodemographic factor among bullies. Predominantly hyperactive (OR=2.285, p=0.00*, CI=1.507-3.467) and inattentive ADHD symptoms reported by teachers (OR=1.829, p=0.03*, CI=1.060-3.154) and parents (OR=1.709, p=0.03*, CI=1.046-2.793) were significant risk factors for bullying behavior while combined symptoms reported by young adolescents (OR=0.729, p=0.01*, CI=0.580-0.915) and teachers (OR=0.643, p=0.02*, CI=0.440-0.938) were protective against bullying behavior despite the influence of conduct behavior (OR=3.160, p=0.00*, CI=1.600-6.241). Internalizing behavior, that is, withdrawn (OR=0.653, p=0.04*, CI=0.436-0.977) and somatic complaints (OR=0.619, p=0.01*, CI=0.430-0.889) significantly protect against bullying behavior.
DISCUSSIONS: Recognizing factors associated with bullying behavior, in particular factors distinctive to the local population, facilitates in strategizing effective interventions for school bullying among young adolescents in Malaysian schools.
The present study evaluated the psychometric properties and factor structure of the Satisfaction With Life Scale (SWLS) in a sample of clinical outpatients in Malaysia. The SWLS is a measure designed to assess subjective life satisfaction. Four hundred eighty-three participants (283 with psychiatric illnesses and 200 with other medical illnesses) completed the SWLS and other self-report instruments. Results of the EFA and CFA supported the fit for the one-factor model as the best-fitting model. The internal consistency of the SWLS (α=0.86) was found to be high. Correlational analyses showed that SWLS had adequate concurrent validity. Scores on SWLS, which differentiated psychiatric patients and medical patients, supported criterion validity. The logistic regression analyses showed good discriminative validity of SWLS. The SWLS is a reliable and valid instrument to measure the satisfaction with life among psychiatry and clinical outpatients in Malaysia.

OBJECTIVE: This study aimed to examine the rate and predictive factors of successful employment at 3 months upon enrolment into an employment program among patients with severe mental illness (SMI).
METHODS: A cross-sectional study using universal sampling technique was conducted on patients with SMI who completed a 3-month period of being employed at Hospital Permai, Malaysia. A total of 147 patients were approached and 126 were finally included in the statistical analyses. Successful employment was defined as the ability to work 40 or more hours per month. Factors significantly associated with successful employment from bivariate analyses were entered into a multiple logistic regression analysis to identify predictors of successful employment.
RESULTS: The rate of successful employment at 3 months was 68.3% (n=81). Significant factors associated with successful employment from bivariate analyses were having past history of working, good family support, less number of psychiatric admissions, good compliance to medicine, good interest in work, living in hostel, being motivated to work, satisfied with the job or salary, getting a preferred job, being in competitive or supported employment and having higher than median scores of PANNS on the positive, negative and general psychopathology. Significant predictors of employment, from a logistic regression model were having good past history of working (p<0.021; OR 6.12; [95% CI 2.1-11.9]) and getting a preferred job (p<0.032; [OR 4.021; 95% CI 1.83-12.1]).
CONCLUSION: Results showed a high employment rate among patients with SMI. Good past history of working and getting a preferred job were significant predictors of successful employment.

The risk variants have been shown to vary substantially across populations and a genetic study in a heterogeneous population might shed a new light in the disease mechanism. This preliminary study aims to determine the frequency of the serotonin transporter gene polymorphism (5-HTTLPR) in the three main ethnic groups in Malaysia and its association with bipolar disorder.
INTRODUCTION: While methadone effectively treats opiate dependence, the side effect of erectile dysfunction (ED) may interfere with treatment adherence and benefits.
AIM:To determine the rate of ED and the associated factors which predict ED in male patients on methadone maintenance therapy (MMT) in a Malaysian population.
MAIN OUTCOME MEASURES: The main outcome measures were the International Index of Erectile Function-15 (IIEF-15) and the Beck Depression Inventory (BDI).
METHODS: A total of 108 participants diagnosed with heroin dependence were assessed. We used the Structured Clinical Interview for DSM-IV Axis-I Disorders (SCID-I) on subjects who received MMT, and they were assessed using the IIEF-15, the BDI, and measures of other clinical and sociodemographic variables.
RESULTS: The rate of ED among men on MMT was 68.5% (mild ED, 36.1%; mild to moderate ED, 22.2%; severe ED, 3.7%). The mean age of the participants was 43.45 years. Older age (P = 0.002), concurrent illicit heroin use (P = 0.024), and having an older partner (P = 0.039) were significantly associated with ED. Following multivariate analysis, it was found that older age was the only significant predictor of ED, with an adjusted odds ratio of 1.07 (95% CI = 1.02-1.16). Methadone dose and duration of methadone treatment were not significantly associated with ED.
CONCLUSION: ED was highly prevalent among male patients on MMT. This suggests that there is a need for routine assessment of sexual function in patients on methadone. Among the risk factors, age was the only factor that was significantly associated with ED. The current use of MMT in Malaysia in terms of dosage and duration did not pose a significant risk for ED.

Enzyme immobilization has been known to be one of the methods to improve the stability and reusability of enzyme. In this study, a strategy to optimize laccase immobilization on polyethylene terephthalate grafted with maleic anhydride electrospun nanofiber mat (PET-g-MAH ENM) was developed. The development involves the screening and optimization processes of the crucial factors that influence the immobilization yield such as enzyme concentration, pH values, covalent bonding (CV) time, CV temperature, crosslinking (CL) time, CL temperature and glutaraldehyde concentration using two-level factorial design and Box-Behnken design (BBD), respectively. It was found that laccase concentration, pH values and glutaraldehyde concentration play important role in enhancing the immobilization yield of laccase on PET-g-MAH ENM in the screening process. Subsequently, the optimization result showed at 0.28 mg/ml laccase concentration, pH 3 and 0.45% (v/v) glutaraldehyde concentrations gave the highest immobilization yield at 87.64% which was 81.2% increment from the immobilization yield before optimization. Under the optimum condition, the immobilized laccase was able to oxidize 2, 2-azino-bis 3-ethylbenzothiazoline-6- sulfonic acid (ABTS) in a broad range of pH (pH 3-6) and temperature (20- 70 °C). Meanwhile, the kinetic parameters for Km and Vmax were 1.331 mM and 0.041 mM/min, respectively. It was concluded that the optimization of immobilized laccase on PET-g-MAH ENM enhance the performance of this biocatalyst.
In recent years, increased interest in Internet Gaming Disorder has led to the development of the Internet Gaming Disorder Scale-Short Form. Translation and subsequent validation of such a scale are important for cross-cultural use. The aim of the present study was to examine the psychometric properties (factor structure, reliability, and validity) of the Malay Version of the Internet Gaming Disorder Scale-Short Form using a sample of Malaysian undergraduates. The present sample included 137 Malaysian undergraduates. Participants completed a self-administered online survey containing demographic items, the Malay Version of the Internet Gaming Disorder Scale-Short Form, the Problematic Online Gaming Questionnaire-Short Form, and the Malay Version of the Internet Addiction Test. The present findings confirm the one-factor model of the Malay Version of the Internet Gaming Disorder Scale-Short Form. Good reliability, as measured by Cronbach alpha, was found for the Malay Version of the Internet Gaming Disorder Scale-Short Form. The Malay Version of the Internet Gaming Disorder Scale-Short Form has demonstrated concurrent validity by significantly correlating with the Problematic Online Gaming Questionnaire-Short Form as well as demonstrated convergent validity with respect to the Malay Version of the Internet Addiction Test. The Malay Version of the Internet Gaming Disorder Scale-Short Form is a reliable and valid tool for assessing Internet Gaming Disorder in Malaysian undergraduates. As more research is still needed to confirm the status of Internet Gaming Disorder as a formal disorder, it is hoped that the Malay Version of the Internet Gaming Disorder Scale-Short Form can facilitate future research examining antecedents and consequences of Internet Gaming Disorder in a Malaysian setting.
