Ng CG, Amer Siddiq AN, Aida SA, Zainal NZ, Koh OH

Asian J Psychiatr, 2010 Mar;3(1):3-6.
PMID: 23051129 DOI: 10.1016/j.ajp.2009.12.001

OBJECTIVE: The aim of this study was to validate the Malay version of the Multidimensional Scale of Perceived Social Support (MSPSS-M) among a group of medical students in Faculty of Medicine, University Malaya.
METHODS: 237 students participated in the study. They were given the Malay version of MSPSS, medical outcome study (MOS) social support survey, Malay version of General Health Questionnaire (GHQ), Malay version of Beck Depression Inventory (BDI) and English version of MSPSS. A week later, these students were again given the Malay version of MSPSS.
RESULTS: The instrument displayed good internal consistency (Cronbach's alpha=0.89), parallel form reliability (0.94) and test-retest reliability (0.77) (Spearman's rho, p<0.01). The negative correlation of the total and subscales of the instrument with the Malay version of GHQ and BDI confirmed its validity. Extraction method of the 12 items MSPSS using principle axis factoring with direct oblimin rotation converged into three factors of perceived social support (Family, Friends and Significant Others) with reliability coefficients of 0.88, 0.82 and 0.94, respectively.
CONCLUSION: The Malay version of the MSPSS demonstrated good psychometric properties in measuring social support among a group of medical students from Faculty of Medicine, University Malaya and it could be used as a simple instrument on young educated Malaysian adolescents.

Asia Pac Psychiatry, 2013 Apr;5 Suppl 1:118-22.
PMID: 23857847 DOI: 10.1111/appy.12056

INTRODUCTION: This study aims to examine the validity and reliability of the Malay version of Attitudes toward Lesbians and Gay Men (MVATL/MVATG) among a group of medical students in Malaysia.
METHODS: It is a cross-sectional study of 173 medical students in the Faculty of Medicine, University of Kuala Lumpur, Malaysia. The participants were given the MVATL/MVATG, Index of Attitudes toward Homosexuals (IATH), Homosexuality Attitude Scale (HAS) and the English version of Attitude toward Lesbians and Gay Men. Two weeks later, these students were given the MVATLG again.
RESULTS: Significant correlation was found between the individual scores of MVATL and MVATG with IATH and HAS in the results. The scale was able to differentiate Muslim and Non-Muslim subjects. The internal consistency (Cronbach's alpha) of both the MVATL and MVATG were good, at 0.76 and 0.82, respectively. The parallel form reliability (Pearson's correlation) of MVATL was 0.0.73 and 0.74 for MVATG. The test-retest reliability of MVATL/MVATG was good (Intraclass correlation coefficient, ICC = 0.67 for MVATL and 0.60 for MVATG).
DISCUSSION: The MVATLG demonstrated good psychometric properties in measuring attitudes toward homosexuality among a group of medical students in Malaysia and it could be used as a simple instrument on young educated Malaysian adults.

Zainal NZ, Nik-Jaafar NR, Baharudin A, Sabki ZA, Ng CG

Asian Pac J Cancer Prev, 2013;14(4):2649-56.
PMID: 23725190

BACKGROUND: Depression is common in breast cancer patients. The aim of this paper was to make a systematic review of its prevalence and associated factors oin breast cancer survivors.
MATERIALS AND METHODS: An extensive systematic electronic review (PUBMED, CINAHL, PsyINFO and Ovid) and handsearch were carried out to retrieve published articles up to November 2012, using Depression OR Dysthymia AND (Cancer OR Tumor OR Neoplasms as the keywords. Information about the design of the studies, measuring scale, characteristics of the participants, prevalence of depression and its associated factors from the included studies were extracted and summarized.
RESULTS: We identified 32 eligible studies that recruited 10,826 breast cancer survivors. Most were cross-sectional or prospective designed. The most frequent instrument used to screen depression was the Center for Epidemiological Studies for Depression (CES-D, n=11 studies) followed by the Beck Depression Inventory (BDI, n=6 studies) and the Hospital Anxiety and Depression Scale (HADS, n=6 studies). CES-D returned about similar prevalence of depression (median=22%, range=13-56%) with BDI (median=22%, range=17-48%) but higher than HADS (median=10%, range=1-22%). Depression was associated with several socio-demographic variables, cancer-related factors, treatment-related factors, subject psychological factors, lifestyle factors, social support and quality of life.
CONCLUSIONS: Breast cancer survivors are at risk for depression so that detection of associated factors is important in clinical practice.

Yee A, Loh HS, Hisham Hashim HM, Ng CG

J Sex Med, 2014 Jan;11(1):22-32.
PMID: 24344738 DOI: 10.1111/jsm.12352

INTRODUCTION: For many years, methadone has been recognized as an effective maintenance treatment for opioid dependence. However, of the many adverse events reported, sexual dysfunction is one of the most common side effects.
AIM: We conducted a meta-analysis to evaluate the prevalence of sexual dysfunction among male patients on methadone and buprenorphine treatments.
METHODS: Relevant studies published from inception until December 2012 were identified by searching PubMed, OVID, and Embase. Studies were selected using prior defined criteria. Heterogeneity, publication bias, and odds ratio were assessed thoroughly.
MAIN OUTCOME MEASURES: To examine the prevalence and odds ratio of sexual dysfunctions among the methadone and buprenorphine groups.
RESULTS: A total of 1,570 participants from 16 eligible studies were identified in this meta-analysis. The studies provided prevalence estimates for sexual dysfunction among methadone users with a meta-analytical pooled prevalence of 52% (95% confidence interval [CI], 0.39-0.65). Only four studies compared sexual dysfunction between the two groups, with a significantly higher combined odds ratio in the methadone group (OR = 4.01, 95% CI, 1.52-10.55, P = 0.0049).
CONCLUSIONS: Evidence showed that the prevalence of sexual dysfunction was higher among the users of methadone compared with buprenorphine. Patients with sexual difficulty while on methadone treatment were advised to switch to buprenorphine.

Ng CG, Boks MP, Roes KC, Zainal NZ, Sulaiman AH, Tan SB, et al.

Eur Neuropsychopharmacol, 2014 Apr;24(4):491-8.
PMID: 24503279 DOI: 10.1016/j.euroneuro.2014.01.016

This is a 4 week, randomized, double-blind, placebo-controlled study to examine the effects of methylphenidate as add-on therapy to mirtazapine compared to placebo for treatment of depression in terminally ill cancer patients. It involved 88 terminally ill cancer patients from University of Malaya Medical Centre, Kuala Lumpur, Malaysia. They were randomized and treated with either methylphenidate or placebo as add on to mirtazapine. The change in Montgomery-Åsberg Depression Rating Scale (MADRS) score from baseline to day 3 was analyzed by linear regression. Changes of MADRS and Clinical Global Impression-Severity Scale (CGI-S) over 28 days were analyzed using mixed model repeated measures (MMRM). Secondary analysis of MADRS response rates, defined as 50% or more reduction from baseline score. A significantly larger reduction of Montgomery-Åsberg Depression Rating Scale (MADRS) score in the methylphenidate group was observed from day 3 (B=4.14; 95% CI=1.83-6.45). Response rate (defined as 50% or more reduction from baseline MADRS score) in the methylphenidate treated group was superior from day 14. Improvement in Clinical Global Impression-Severity Scale (CGI-S) was greater in the methylphenidate treated group from day 3 until day 28. The drop-out rates were 52.3% in the methylphenidate group and 59.1% in the placebo group (relative risk=0.86, 95%CI=0.54-1.37) due to cancer progression. Nervous system adverse events were more common in methylphenidate treated subjects (20.5% vs 9.1%, p=0.13). In conclusions, methylphenidate as add on therapy to mirtazapine demonstrated an earlier antidepressant response in terminally ill cancer patients, although at an increased risk of the nervous system side effects.

Ng CG, Chin SC, Yee AH, Loh HS, Sulaiman AH, Sherianne Sook Kuan W, et al.

Malays J Med Sci, 2014 May;21(3):62-70.
PMID: 25246837

BACKGROUND: The Snaith-Hamilton Pleasure Scale (SHAPS) is a self-assessment scale designed to evaluate anhedonia in various psychiatric disorders. In order to facilitate its use in Malaysian settings, our current study aimed to examine the validity of a Malay-translated version of the SHAPS (SHAPS-M).
METHODS: In this cross-sectional study, a total of 44 depressed patients and 82 healthy subjects were recruited from a university out-patient clinic. All participants were given both the Malay and English versions of the SHAPS, Fawcett-Clark Pleasure Scale (FCPS), General Health Questionnaire 12 (GHQ-12), and the Beck Depression Inventory (BDI) to assess their hedonic state, general mental health condition and levels of depression.
RESULTS: The results showed that the SHAPS-M has impressive internal consistency (α = 0.96), concurrent validity and good parallel-form reliability (intraclass coefficient, ICC = 0.65).
CONCLUSION: In addition to demonstrating good psychometric properties, the SHAPS-M is easy to administer. Therefore, it is a valid, reliable, and suitable questionnaire for assessing anhedonia among depressed patients in Malaysia.

PMID: 25417950 MyJurnal

Depression is a debilitating illness and has become a leading cause of morbidity globally. We aim to summarise the evidence available in regard to the prevalence, type of assessment tools used and treatment options for depression in Malaysia. Two hundred and forty seven articles related to depression were found in a search through a database dedicated to indexing all original data relevant to medicine published in Malaysia between the years 2000-2013. Fifty seven articles were selected and reviewed on the basis of clinical relevance and future research implications. Findings were summarised, categorised and presented according to prevalence of depression, depression in women, depression in clinical condition, assessment tools, and treatment of depression. The prevalence of depression in Malaysia was estimated to be between 8 and 12%. The figures were higher among women of low socio-economic background or those with comorbid medical condition. The common assessment tools used in Malaysia include Beck Depression Inventory (BDI), Depression, Anxiety and Stress Scale (DASS), Patient Health Questionnaire 9 (PHQ-9) and Hospital Anxiety and Depression Scale (HADS). They were translated into the Malay language and their psychometric properties were established. Both pharmacological treatment and psychotherapy were commonly used in Malaysia, and were highly recommended in local clinical practice guidelines. There are discrepancies in the reported rates of depression in Malaysia and this needs to be addressed. There were lack of studies looking into the depression among subgroups in Malaysia especially in the male population. There were several instruments available for assessment of depression in Malaysia but their suitability for the local setting need further research. Both pharmacotherapy and psychotherapy were recommended in the local treatment guideline in Malaysia. With the emergence of generic medication, we need to compare their clinical efficacy and tolerability with original products.

Anhedonia among patients with Major Depressive Disorder: A comparison between patients on escitalopram and healthy controls

Ng CG, Wong SK, Loh HS, Yee A

Clin Ter, 2014;165(6):e384-90.
PMID: 25524191 DOI: 10.7417/CT.2014.1778

BACKGROUND AND AIMS: Escitalopram has widely been recognized as one of the most frequently used antidepressants, with superior tolerability and great efficacy in preventing major depressive disorder (MDD) relapse and recurrence. However, anhedonia, which is a core symptom of MDD, remains difficult to treat. This study investigates the hedonic levels of MDD patients treated with Escitalopram.

MATERIALS AND METHODS: A total of 108 participants, 26 of whom with MDD on Escitalopram, were recruited in this cross sectional study. They were evaluated using the Snaith-Hamilton Pleasure Scale (SHAPS) and Beck Depression Inventory (BDI) questionnaires to assess their hedonic state, general mental health condition and level of depression.

RESULTS: Our study shows that most items in the SHAPS scores are significantly different between MDD patients on Escitalopram and the controls.

CONCLUSIONS: The hedonic capacity remains different between the two groups despite patients with MDD are put on Escitalopram treatment. Escitalopram fails to alleviate the hedonic state of MDD patients. Antidepressants that improve both depressive symptoms and hedonic states should be considered when treating MDD patients in clinical settings.

Clin Ter, 2014;165(6):287-93.
PMID: 25524183 DOI: 10.7417/CT.2014.1770

OBJECTIVES: There is a lack of local instruments to assess behavioural and psychological symptoms of dementia (BPSD). This 2-stage cross-sectional study was aimed at validating a Malay translated version of the Neuropsychiaric Inventory (MvNPI).

MATERIALS AND METHODS: It was conducted on a selected group of 138 elderly outpatients with dementia and their caregivers in Hospital Pulau Pinang. Severity of dementia was assessed using the Malay-translated version of Mini Mental State Examination (MMSE). The original NPI was translated and then back-translated before it was pilot-tested. The MvNPI was administered twice, a week apart on the same caregiver by the same investigator.

RESULTS: The individual items and total scale score of MvNPI had high internal consistency, with Corrected Item-Total Correlation ranging from satisfactory to good (0.41 to 0.77). The Cronbach's alpha for all the NPI domains showed high internal consistency (0.83), and subtotal for severity and distress scores were perfect (0.998 to 1.00). There was no significant difference between test-retest mean scores (p>0.05) and their correlations were perfect (0.996 to 1.00). Content validity indicated mild and inverse relationship between MMSE scores and severity, and distress score (-0.281 and -0.268, respectively, with p<0.001). Discriminant validity calculated using Mann-Whitney U test was found to be significant (p<0.001) in differentiating severity of cognitive impairment. Factor analysis revealed four possible components existed in MvNPI.

CONCLUSIONS: The MvNPI is a valid and reliable tool for assessing BPSD among Malay speaking populations of Malaysia and its neighbouring South East Asian countries.

Asian Pac J Cancer Prev, 2014;15(10):4261-4.
PMID: 24935381

OBJECTIVE: To examine the prescription rates in cancer patients of three common psychotropic drugs: anxiolytic/ hypnotic, antidepressant and antipsychotic.
MATERIALS AND METHODS: In this retrospective cohort study, data were extracted from the pharmacy database of University Malaya Medical Center (UMMC) responsible for dispensing records of patients stored in the pharmacy's Medication Management and Use System (Ascribe). We analyzed the use of psychotropics in patients from the oncology ward and cardiology from 2008 to 2012. Odds ratios (ORs) were adjusted for age, gender and ethnicity.
RESULTS: A total of 3,345 oncology patients and 8,980 cardiology patients were included. Oncology patients were significantly more often prescribed psychotropic drugs (adjusted OR: anxiolytic/hypnotic=5.55 (CI: 4.64-6.63); antidepressants=6.08 (CI: 4.83-7.64) and antipsychotics=5.41 (CI: 4.17-7.02). Non-Malay female cancer patients were at significantly higher risk of anxiolytic/hypnotic use.
CONCLUSIONS: Psychotropic drugs prescription is common in cancer patients. Anxiolytic/hypnotic prescription rates are significantly higher in non-Malay female patients in Malaysia.
Fulltext Culturable bacterial microbiota of the stomach of Helicobacter pylori positive and negative gastric disease patients

PMID: 25105162 DOI: 10.1155/2014/610421

Human stomach is the only known natural habitat of Helicobacter pylori (Hp), a major bacterial pathogen that causes different gastroduodenal diseases. Despite this, the impact of Hp on the diversity and the composition of the gastric microbiota has been poorly studied. In this study, we have analyzed the culturable gastric microbiota of 215 Malaysian patients, including 131 Hp positive and 84 Hp negative individuals that were affected by different gastric diseases. Non-Hp bacteria isolated from biopsy samples were identified by matrix assisted laser desorption ionization-time of flight mass spectrometry based biotyping and 16SrRNA sequencing. The presence of Hp did not significantly modify the diversity of the gastric microbiota. However, correlation was observed between the isolation of Streptococci and peptic ulcer disease. In addition, as a first report, Burkholderia pseudomallei was also isolated from the gastric samples of the local population. This study suggested that there may be geographical variations in the diversity of the human gastric microbiome. Geographically linked diversity in the gastric microbiome and possible interactions between Hp and other bacterial species from stomach microbiota in pathogenesis are proposed for further investigations.

Int J Impot Res, 2014 Sep-Oct;26(5):161-6.
PMID: 24990199 DOI: 10.1038/ijir.2014.18

Methadone maintenance treatment is proven to be effective treatment for opioid dependence. Of the many adverse events reported, sexual dysfunction is one of the most common side effects. However, there may be other clinical factors that are associated with sexual dysfunction among methadone users. We conducted a meta-analysis to examine the clinical factors associated with sexual dysfunction among male patients on methadone and buprenorphine treatments, of which eligible studies were selected using prior defined criteria. A total of 2619 participants from 16 eligible studies, published from inception till December 2012, were identified from the PubMed, OVID and EMBASE databases. The included studies provided prevalence estimates for sexual dysfunction among methadone users with a meta-analytical pooled prevalence of 52% (95% confidence interval (CI), 0.39-0.65). Only four studies compared sexual dysfunction between the two groups, with a significantly higher combined odds ratio in the methadone group (odds ratio=4.01, 95% CI, 1.52-10.55, P=0.0049). Our study shows that eight clinical factors are associated with sexual dysfunction among men receiving opioid substitution treatment, namely age, hormone assays, duration of treatment, methadone dose, medical status, psychiatric illness, other current substance use and familial status, and methadone versus buprenorphine treatment. Despite the methodological limitations, the findings of this meta-analysis study may offer better insights to clinicians in dealing with both sexual dysfunction and its related problems.
