Neuropathic pain is a chronic pain condition persisting past the presence of any noxious stimulus or inflammation. Zerumbone, of the Zingiber zerumbet ginger plant, has exhibited anti-allodynic and antihyperalgesic effects in a neuropathic pain animal model, amongst other pharmacological properties. This study was conducted to further elucidate the mechanisms underlying zerumbone's antineuropathic actions. Research on therapeutic agents involving cannabinoid (CB) and peroxisome proliferator-activated receptors (PPARs) is rising. These receptor systems have shown importance in causing a synergistic effect in suppressing nociceptive processing. Behavioural responses were assessed using the von Frey filament test (mechanical allodynia) and Hargreaves plantar test (thermal hyperalgesia), in chronic constriction injury (CCI) neuropathic pain mice. Antagonists SR141716 (CB1 receptor), SR144528 (CB2 receptor), GW6471 (PPARα receptor) and GW9662 (PPARγ receptor) were pre-administered before the zerumbone treatment. Our findings indicated the involvement of CB1, PPARα and PPARγ in zerumbone's action against mechanical allodynia, whereas only CB1 and PPARα were involved against thermal hyperalgesia. Molecular docking studies also suggest that zerumbone has a comparable and favourable binding affinity against the respective agonist on the CB and PPAR receptors studied. This finding will contribute to advance our knowledge on zerumbone and its significance in treating neuropathic pain.

INTRODUCTION: E-cigarette use is an emerging phenomenon with increasing recognition and acceptance globally. This study aims to create a profile of e-cigarette users among university students in Malaysia.

METHODS: The study was conducted using a cross-sectional research involving six universities in Malaysia. A semi-structured questionnaire was distributed to 1302 randomly selected students, who either smoked cigarettes and/or e-cigarettes. The 2011 version of Global Adult Tobacco Surveys (GATS) tool was used to record the respondents' sociodemographic data.

RESULTS: The study revealed that 74.9% of the respondents smoked e-cigarettes; 40.3% used both cigarettes and e-cigarettes (dual users), and 34.5% were exclusive e-cigarette users. The exclusive use of e-cigarettes was related to gender (OR=0.18, 95% CI: 0.09-0.39). Also, male respondents were the majority users (95%). Of the respondents, 75.2 % were Malays, 98.0% single and most believed they have no health problems (92.1%). Further findings revealed the occurrence of adverse effects, dizziness 14.4%, cough 14.1%, and headaches 12.4%. Overall, 57.8% of the respondents used e-cigarettes as a smoking cessation tool, while others consider e-cigarettes a self-image enhancing tool or as part of social activities.

CONCLUSIONS: Further research on the use of e-cigarettes should be conducted on a large number of respondents in other settings to augment the findings of this study, and also guide policy making on and prevention practice of e-cigarette use, among the general student population in Malaysia.
Fulltext The efficacy of molecular markers analysis with integration of sensory methods in detection of aroma in rice

Allele Specific Amplification with four primers (External Antisense Primer, External Sense Primer, Internal Nonfragrant Sense Primer, and Internal Fragrant Antisense Primer) and sensory evaluation with leaves and grains were executed to identify aromatic rice genotypes and their F1 individuals derived from different crosses of 2 Malaysian varieties with 4 popular land races and 3 advance lines. Homozygous aromatic (fgr/fgr) F1 individuals demonstrated better aroma scores compared to both heterozygous nonaromatic (FGR/fgr) and homozygous nonaromatic (FGR/FGR) individuals, while, some F1 individuals expressed aroma in both leaf and grain aromatic tests without possessing the fgr allele. Genotypic analysis of F1 individuals for the fgr gene represented homozygous aromatic, heterozygous nonaromatic and homozygous nonaromatic genotypes in the ratio 20:19:3. Genotypic and phenotypic analysis revealed that aroma in F1 individuals was successfully inherited from the parents, but either molecular analysis or sensory evaluation alone could not determine aromatic condition completely. The integration of molecular analysis with sensory methods was observed as rapid and reliable for the screening of aromatic genotypes because molecular analysis could distinguish aromatic homozygous, nonaromatic homozygous and nonaromatic heterozygous individuals, whilst the sensory method facilitated the evaluation of aroma emitted from leaf and grain during flowering to maturity stages.
The Role of Atypical Antipsychotics in Sexuality: Road to Recovery in Schizophrenia

Sexuality is an important dimension in human beings as a form of expression of individuality. For many decades, sexual functioning has been a neglected area among patients suffering from schizophrenia. It was a presumption that patients with schizophrenia could be asexual and this could be secondary to overwhelming situations of delusion, hallucination, hostility and negative symptoms among others. The deficient in sexual functioning are due to innate factors, i.e. negative symptoms (apathy, avolition and amotivation) and also as a result of prefrontal dysfunction, i.e. inability to plan and execute meaningful relationship. Adverse effects of the psychopharmacological agents, especially the typical antipsychotics, e.g. dystonia, excessive sedation and hyperprolactinemia may interfere with patients' sexual activity. In this review, we highlight the neurobiology of schizophrenia in the context of understanding sexual functioning and to integrate the knowledge of dopamine-serotonin neurotransmitter's interaction and the receptors' target. Interventional approaches consist of psychopharmacological and psychosocial interventions. In the perspective of sexuality, we recommend atypical antipsychotic should be placed as the first line treatment for both drug naïve patients and also to patients who are already receiving psychopharmacological agents in consideration for a drug-switch from typical to atypical antipsychotics. Aripiprazole, clozapine, olanzapine and quetiapine exert benefits in terms of sexual functioning recovery due to their atypical mechanism of action. However, the potential adverse effect like metabolic syndrome should be adequately managed to prevent negative consequences. Psychosocial interventions, i.e. psychoeducation, destigmatization, supportive psychotherapy and psychiatric rehabilitation also play a crucial role in the management. In conclusion, restoration of sexual function is an achievable recovery target in patients with schizophrenia through these biopsycho- social interventions.
The Novelty of Bupropion As a Dopaminergic Antidepressant for the Treatment of Adult Attention Deficit Hyperactive Disorder

Deang KT, Sidi H, Zakaria H, Adam RL, Das S, Hatta NH, et al.

Curr Drug Targets, 2019;20(2):210-219.

Attention deficit hyperactive disorder (ADHD), a hyperactivity disorder prevalent among children may continue as an adulthood attention deficit. To date, treating an individual with an adult ADHD may be an arduous task as it involves numerous challenges, which include a need for high index of suspicion to diagnose this medical condition. Many psychiatric disorders masquerade as ADHD and delay the necessary assessment and proper treatment for this debilitating medical disorder. Adult ADHD is often misdiagnosed (or under diagnosed) due to the fact that this medical condition is being masked by the patients' high level of intellectual achievement. As the ADHD in adult persists, it may end-up with impairment in the personal-social-occupational function in which the management becomes a great challenge. The treatment of ADHD can be optimized by using various drugs targets agents like norepinephrine-dopamine reuptake inhibitor (NDRI), with or without psycho stimulants like methylphenidate, which is marketed as Ritalin. Bupropion, an NDRI has a novel effect on ADHD as the molecule exerts its effects by modulating the reward-pleasure mesolimbic dopaminergic system and at the same time regulates the elevating mood dimension of the noradrenergic neurotransmission. The role of Bupropion in the neural and psychopharmacological perspective treatment of ADHD was deliberated. The present review highlights the novel effects of Bupropion in ADHD treatment, together with the help of other successful bio-psycho-social measures. This may be of immense benefit to the psychiatrists for treating their patients.
Fulltext Reducing the stigma of mental health disorders with a focus on low- and middle-income countries

Mental health disorders are a burgeoning global public health challenge, and disproportionately affect the poor. Low- and middle-income countries (LMICs) bear 80 % of the mental health disease burden. Stigma associated with mental health results in delayed help seeking, reduced access to health services, suboptimal treatment, poor outcomes and an increased risk of individuals' human rights violations. Moreover, widespread co-occurrence of physical comorbidities such as noncommunicable diseases with mental health disorders makes the treatment of both conditions challenging and worsens prognosis. This paper explores various aspects of stigma towards mental health with a focus on LMICs and assesses measures to increase help-seeking and access to and uptake of mental health services. Stigma impacts persons living with mental illness, their families and caregivers and healthcare professionals (mental health professionals, non-psychiatric specialists and general practitioners) imparting mental health care. Cultural, socio-economic and religious factors determine various aspects of mental health in LMICs, ranging from perceptions of health and illness, health seeking behavior, attitudes of the individuals and health practitioners and mental health systems. Addressing stigma requires comprehensive and inclusive mental health policies and legislations; sustainable and culturally-adapted awareness programs; capacity building of mental health workforce through task-shifting and interprofessional approaches; and improved access to mental health services by integration with primary healthcare and utilizing existing pathways of care. Future strategies targeting stigma reduction must consider the enormous physical comorbidity burden associated with mental health, prioritize workplace interventions and importantly, address the deterioration of population mental health from the COVID-19 pandemic.

Sariah M, Choo CW, Zakaria H, Norihan MS

Mycopathologia, 2005 Jan;159(1):113-7.
PMID: 15750742

Basal stem rot of oil palm caused by Ganoderma boninense is of major economic importance. Observations of the low incidence of disease due to Ganoderma species in natural stands, suggest that the disease is kept under control by some biological means. Trichoderma spp. are saprophytic fungi with high antagonistic activities against soil-borne pathogens. However, their abundance and distribution are soil and crop specific. Trichoderma species have been found to be concentrated in the A1 (0-30 cm) and Be soil horizons (30-60 cm), although the abundance of Trichoderma was not significantly different between the oil palm and non-oil palm ecosystems. Characterisation of Trichoderma isolates based on cultural, morphological and DNA polymorphism showed that T. harzianum, T. virens, T. koningii and T. longibrachiatum made up 72, 14, 10 and 4% of the total Trichoderma isolates isolated. As Trichoderma species are present in the oil palm ecosystem, but at lower numbers and in locations different from those desired, soil augmentation with antagonistic Trichoderma spp. can be developed as a strategy towards integrated management of basal stem rot of oil palm.

Problematic alcohol use and depression in secondary school students in Miri, Malaysia

Chhoa KH, Zakaria H, Abd Rahman FN

Pediatr Int, 2019 Mar;61(3):284-292.
PMID: 30636372 DOI: 10.1111/ped.13789

BACKGROUND: Alcohol consumption in the under-aged is one of the main concerns regarding Malaysian adolescents. There is no previous study on problematic alcohol use (PAU) in adolescents in Sarawak. The aim of this study was to determine the prevalence of PAU, its associated variables and its relationship with depression.
METHODS: This was a cross-sectional study. A total of 327 secondary school students completed the Alcohol Use Disorder Identification Test and Children's Depression Inventory, and a sociodemographic questionnaire. Binary and multivariable logistic regression were used to examine the relationship between the different variables.
RESULTS: A total of 42.2% of adolescents had PAU. Urban adolescents had a higher prevalence compared with rural adolescents (OR, 1.612; 95% CI: 1.036-2.508 P = 0.034). Female adolescents (56.8%) and Bumiputera Sarawak adolescents (76.8%) comprised a large proportion of the respondents with PAU. Cultural norm (78.3%) and curiosity (68.1%) were the two main reasons for PAU. Only family history of alcohol use (OR, 2.273; 95% CI: 1.013-5.107; P = 0.047), ever consumed alcohol (OR, 57.585; 95% CI: 21.885-151.525; P

Despite an enormous number of studies addressing the importance of posttraumatic growth (PTG) among cancer patients, the literature lacks data regarding how different coping strategies affect PTG among head and neck cancer (HNC) patients over time. This longitudinal study investigated the PTG trend and coping over 5-7months among a cohort of HNC patients within the first year after their diagnosis. It determined an association between coping strategies and PTG over time. The study's HNC respondents were administered a socio-demographic and clinical characteristics questionnaire during their baseline assessments. Additionally, the Malay versions of the "PTG Inventory-Short Form" (PTGI-SF) and the "Brief Coping Orientation to Problems Experienced Inventory" (Brief COPE) were administered during respondents' baseline assessments and follow-up assessments (5-7months after the baseline assessments). In total, 200 respondents reported an increasing PTG trend and approach coping (active coping, planning, positive reframing, acceptance, emotional support, and instrumental support) and a decreasing trend of avoidant coping (self-distraction and denial) over time. Two approach coping strategies (acceptance and planning) significantly increased PTG while denial was the only avoidant coping strategy that significantly lowered PTG, after controlling for socio-demographic and clinical characteristics, over time. Our study's findings identified the need to incorporate psychosocial interventions that enhance approach coping and reduce avoidant coping into HNC patients' treatment regimes.

PMID: 32765135 DOI: 10.2147/RMHP.S256165

Introduction: Noncommunicable diseases (NCDs) are the leading cause of morbidity and mortality in the Association of Southeast Asian Nations (ASEAN) member states. Progress has been slow despite the World Health Organization action plan for the prevention and control of NCDs in the region. This paper presents recommendations focused on practical strategies for optimizing NCD management in the ASEAN region.
Methods: A multidisciplinary group of experts from six ASEAN member states convened for two face-to-face meetings to discuss barriers and possible recommendations for optimizing NCD management, focused on cardiovascular diseases and mental disorders, in the region. Multiple approaches, ie, analysis of insights from the meetings and a review of existing literature on NCD programs in the ASEAN region were followed. The proposed recommendations were also based on selected successful interventions in ASEAN member states, thus providing actionable strategies.
Results: The gaps identified in NCD management for cardiovascular diseases and mental disorders in the ASEAN region were classified into gaps relating to policies and to clinical and public health practice. The proposed solutions addressing policy gaps include fostering multisectoral public-private partnerships, employing "whole-of-government" and "whole-of-society" approaches and promoting "health-in-all policies approach" to manage issues with financing, accessibility, efficiency and quality of health services. Whereas proposed solutions to bridge clinical and public health practice gaps entail strengthening primary care services, building the capacity of trained healthcare workers and employing collaborative care for holistic management of patients.
Conclusion: The scale of premature and preventable deaths from NCDs in the ASEAN region remains a serious public health concern and requires a "whole-of-system approach". The interventions proposed in this paper build on regional collaborations and knowledge sharing to help develop a concerted and targeted response to NCDs.
Loss of CXC-Chemokine Receptor 1 Expression in Chorioamnionitis Is Associated with Adverse Perinatal Outcomes

Wong YP, Wagiman N, Tan JW, Hanim BS, Rashidan MSH, Fong KM, et al.

Diagnostics (Basel), 2022 Apr 01;12(4).
PMID: 35453930 DOI: 10.3390/diagnostics12040882

Background: Chorioamnionitis complicates about 1−5% of deliveries at term and causes about one-third of stillbirths. CXC-chemokine receptor 1 (CXCR1) binds IL-8 with high affinity and regulates neutrophil recruitment. We aimed to determine the immunoexpression of CXCR1 in placentas with chorioamnionitis, and its association with adverse perinatal outcomes. Methods: A total of 101 cases of chorioamnionitis and 32 cases of non-chorioamnionitis were recruited over a period of 2 years. CXCR1 immunohistochemistry was performed, and its immunoexpression in placentas was evaluated. The adverse perinatal outcomes included intrauterine death, poor APGAR score, early neonatal death, and respiratory complications. Results: Seventeen cases (17/101, 16.8%) with chorioamnionitis presented as preterm deliveries. Lung complications were more common in mothers who were >35 years (p = 0.003) and with a higher stage in the foetal inflammatory response (p = 0.03). Notably, 24 cases (23.8%) of histological chorioamnionitis were not detected clinically. Interestingly, the loss of CXCR1 immunoexpression in the umbilical cord endothelial cells (UCECs) was significantly associated with foetal death (p = 0.009). Conclusion: The loss of CXCR1 expression in UCECs was significantly associated with an increased risk of adverse perinatal outcomes and could be used as a biomarker to predict adverse perinatal outcomes in chorioamnionitis. Further study is warranted to study the pathophysiology involved in the failure of CXCR1 expression in these cells.

Psychodyn Psychiatry, 2017;45(1):45-57.
PMID: 28248565 DOI: 10.1521/pdps.2017.45.1.45

The subjective nature of psychodynamic psychotherapy (PP) makes training and supervision more abstract compared to other forms of psychotherapy. The issues encountered in the learning and supervision process of PP of Malaysian psychiatry trainees are discussed in this article. Issues of preparation before starting PP, case selection, assessment of patients, dynamic formulations, supervision, anxieties in the therapy, countertransference, termination of therapy, the treatment alliance, transfer of care, the therapeutic setting, and bioethical considerations are explored. Everyone's experience of learning PP is unique and there is no algorithmic approach to its practice. With creative thinking, effort, and "good enough" supervision, a trainee can improve PP skills, even in underserved areas of the world.
Knowledge and attitude on sex among medical students of a Malaysian university: a comparison study

Sidi H, Loh SF, Mahadevan R, Puteh SE, Musa R, Wong CY, et al.

Asia Pac Psychiatry, 2013 Apr;5 Suppl 1:103-9.
PMID: 23857845 DOI: 10.1111/appy.12053

INTRODUCTION: The objective of this study was to determine the relationship between clinical/socio-demographic factors with knowledge and attitude on sex among medical students of the National University of Malaysia (UKM).
METHODS: A cross-sectional study assessing 452 students using a self-administered questionnaire of knowledge and attitude was performed and had a response rate of 80%.
RESULTS: The majority of respondents were Malays (56%), females (57.5%), lived in urban areas (66.4%), had a median family income of RM3000 and perceived themselves as moderately religious (60%). The overall score on knowledge about sex was 21.7 of 35 (a higher score indicates better knowledge about sex). It was noted that 73.2% of students felt that they did not receive adequate training in medical school to deal with patients' sexuality and sexual problems, while 51.5% felt uncomfortable talking to patients about these issues. Students in the clinical year were more knowledgeable than those in pre-clinical years (22.67 versus 20.71, P 22 marks [median score]).
DISCUSSION: The students' attitude on sex was considered conservative as the majority of them disagreed on premarital sex, masturbation, abortion, homosexuality and oral sex. Gender and religiosity have a large influence on attitudes on controversial sexual issues, whereas clinical status plays a small role. Knowledge on sex among UKM medical students is inadequate and their attitudes on sex are considered conservative. Integration of sexual medicine and health modules in the medical curriculum is crucial for students to more effectively address patients' sexual problems and promote non-judgmental attitudes towards patients.

Kernel elongation in rice

Golam F, Prodhan ZH

J Sci Food Agric, 2013 Feb;93(3):449-56.
PMID: 23238771 DOI: 10.1002/jsfa.5983

Kernel elongation after cooking is an important character of fine rice and most rice consumers prefer length-wise elongation. Although improvement of aromatic rice began early in the 1970s, until now the mechanisms and genetics of kernel elongation has remained unrevealed. Kernel elongation is considered as a physical phenomenon and is influenced by several physicochemical and genetic factors, including genotypes, aging temperature, aging time, water uptake, amylose content and gelatinization temperature. Recently the complete genetic map of fine rice has been created and the gene responsible for kernel length identified; moreover, this gene is tightly linked with the cooked kernel elongation trait. Several molecular markers linked with cooked kernel elongation have been developed. These tools will be helpful for the improvement of this important trait. For the proper study of cooked kernel elongation of rice, this review paper will provide the basis and directional materials for further studies.
Fulltext Internet addiction and its relationship with attention deficit hyperactivity disorder (ADHD) symptoms, anxiety and stress among university students in Malaysia

Zakaria H, Hussain I, Zulkifli NS, Ibrahim N, Noriza NJ, Wong M, et al.

PLoS One, 2023;18(7):e0283862.
PMID: 37506072 DOI: 10.1371/journal.pone.0283862

BACKGROUND AND AIMS: There is growing evidence on the contribution of psychological factors to internet addiction; yet it remains inconsistent and deserves further exploration. The aim of this study was to determine the relationship between the psychological symptoms (Attention Deficit Hyperactivity Disorder (ADHD) symptoms, stress, depression, anxiety and loneliness) and internet addiction (IA) among the university students in Malaysia.
MATERIALS AND METHODS: A total of 480 students from different faculties in a Malaysian public university participated in this study. They were selected by simple random sampling method. They completed self-administered questionnaires including the Malay Version of Internet Addiction Test (MVIAT)) to measure internet addiction and Adult Self-Report Scale (ASRS) Symptom Checklist, Depression Anxiety Stress Scales (DASS) and UCLA Loneliness Scale (Version 3) to assess for ADHD symptoms, depression, anxiety, stress, and loneliness respectively.
RESULTS: The prevalence of IA among university students was 33.33% (n = 160). The respondents' mean age was 21.01 ± 1.29 years old and they were predominantly females (73.1%) and Malays (59.4%). Binary logistic regression showed that gender (p = 0.002; OR = 0.463, CI = 0.284-0.754), ADHD inattention (p = 0.003; OR = 2.063, CI = 1.273-3.345), ADHD hyperactivity (p<0.0001; OR = 2.427, CI = 1.495-3.939), stress (p = 0.048; OR = 1.795, CI = 1.004-3.210) and loneliness (p = 0.022; OR = 1.741, CI = 1.084-2.794) were significantly associated with IA.
CONCLUSION: A third of university students had IA. In addition, we found that those who were at risk of IA were males, with ADHD symptoms of inattention and hyperactivity, who reported stress and loneliness. Preventive strategy to curb internet addiction and its negative sequelae may consider these factors in its development and implementation.
Innovative Educational Initiatives to Train Psychodynamic Psychiatrists in Underserved Areas of the World

Alfonso CA, Michael MC, Elvira SD, Zakaria H, Kalayasiri R, Adlan ASA, et al.

Psychiatr. Clin. North Am., 2018 06;41(2):305-318.
PMID: 29739528 DOI: 10.1016/j.psc.2018.01.010

Psychodynamic psychiatry remains a challenging subject to teach in underserved areas, where enthusiasm to learn is substantial. Besides logistical and psychiatric workforce shortcomings, sensible cultural adaptations to make psychodynamic psychiatry relevant outside of high-income countries require creative effort. Innovative pedagogical methods that include carefully crafted mentoring and incorporate videoconferencing in combination with site visits can be implemented through international collaborations. Emphasis on mentoring is essential to adequately train future psychodynamic psychotherapy supervisors. Examples of World Psychiatric Association initiatives in countries such as Indonesia, Iran, Malaysia, and Thailand are presented as possible models to emulate elsewhere.
High-performance thin-layer chromatographic methods in the evaluation of the antioxidant and anti-hyperglycemic activity of Myrmecodia platytyrea as a promising opportunity in diabetes treatment

Agatonovic-Kustrin S, Morton DW, Adam A, Mizaton HH, Zakaria H

J Chromatogr A, 2017 Dec 29;1530:192-196.
PMID: 29132827 DOI: 10.1016/j.chroma.2017.11.012

The steady increase of diabetes is becoming a major burden on health care systems. As diabetic complications arise from oxidative stress, an antioxidant therapy along with anti-diabetic drugs is recommended. Myrmecodia or ant plant is highly valued as a traditional medicine in West Papua. It is used as an alternative treatment for diabetes, as the substances produced by ants can reduce blood sugar levels. The aim of this study was to develop and establish high-performance thin-layer chromatographic (HPTLC)-bioautographic methods to measure the antioxidant and hypoglycemic effects in different extracts from Myrmecodia platytyrea and to compare them with sterol content. Antioxidant activity in methanol, ethanol, dichloromethane (DCM) and ethyl acetate (EA) extracts were measured with a direct HPTLC-2,2-diphenyl-1-picrylhydrazyl free radical (DPPH) assay, while hypoglycemic effects were assessed using a newly developed α-amylase inhibitory activity assay. Stigmasterol is observed, after derivatization with anisaldehyde, as purple colored zones under visible light at hRF values of 0.66. The highest antioxidant activity was observed in the ethanol extract which is rich in polyphenols and flavonoids, while the DCM extract did not show antioxidant activity, but had significant α-amylase inhibitory activity. The highest α-amylase inhibitory activity was observed in the EA and DCM extracts and was related to their stigmasterol content.
