    INTRODUCTION: The Three-Factor Eating Questionnaire was first constructed to measure eating behavior in an English population in the United States. It has been validated and translated for various populations in different languages. The aim of this article is to describe a systematic process for translating the questionnaire from English to Malay language.

    METHODOLOGY: The report of the International Society for Pharmacoeconomics and Outcome Research (ISPOR) Task Force was used as the basis for the systematic translation process. The process began with preparation; followed by forward translation (2 independent translators), reconciliation, back translation (2 independent translators), back translation review, harmonization, cognitive debriefing, review of cognitive debriefing results and finalization, proofreading; and ended with the final report. Four independent Malay translators who fluent in English and reside in Malaysia were involved in the process. A team of health care researchers had assisted the review of the new translated questionnaires.

    RESULTS: Majority of the TFEQ-R21 items were experiencing, conceptually and semantically equivalence between original English and translated English. However, certain phrase such as "feels like bottomless pit" was difficult to translate by forward translators. Cognitive debriefing was a very helpful process to ensure the TFEQ-R21 Malay version was appropriate in term of wording and culturally accepted. A total of four redundant comments in regards to response scale wording, word confusion and wording arrangement.

    CONCLUSION: The systematic translation process is a way to reduce the linguistic discrepancies between the English and Malay language in order to promote equivalence and culturally adapted TFEQ-R21 questionnaire.

    OBJECTIVE: Comparative trials of benzoyl peroxide (BPO) have yielded contradictory results on its effectiveness for acne vulgaris. The aim of the study was to synthesise the evidence for the effectiveness of BPO-containing topical products for facial acne vulgaris.
    DESIGN: Systematic review.
    METHODS: The Cochrane Central Register of Controlled trials, Cochrane Library, MEDLINE and other relevant databases were searched without publication date or language restriction.
    RESULTS: We identified 22 trials involving 2212 participants; 12 trials compared BPO as single agent while the other 10 trials compared BPO in combination products. All trials reported lesion count as the outcome measure but only five trials provided numerical data. However, pooling of data from these trials was inappropriate due to variations between trials in terms of acne severity, comparator used and trial duration. Overall the study quality was fair but most studies had some bias particularly in method of random generation and allocation concealment. Although the results provide some evidence that BPO reduces acne-lesion count, the available evidence is not robust enough for firm conclusions.
    CONCLUSIONS: There is no high quality evidence that topical BPO improves facial acne vulgaris, and further research is needed.

    A molecular docking tool of AutoDock3.05 was evaluated for its ability to reproduce experimentally determined affinities of various sialic acid analogues toward hemagglutinin of influenza A virus. With the exception of those with a C6-modified glycerol side chain, the experimental binding affinities of most sialic acid analogues (C2, C4 and C5-substituted) determined by viral hemadsorption inhibition assay, hemagglutination inhibition assay and nuclear magnetic resonance correlated well with the computationally estimated free energy of binding. Sialic acid analogues with modified glycerol side chains showed only poor correlation between the experimentally determined hemagglutinin inhibitor affinities and AutoDock3.05 scores, suggesting high mobility of the glutamic acid side chain at the glycerol binding pocket, which is difficult to simulate using a flexi-rigid molecular docking approach. In conclusion, except for some glycerol-substituted sialic acid analogues, the results showed the effectiveness of AutoDock3.05 searching and scoring functions in estimating affinities of sialic acid analogues toward influenza A hemagglutinin, making it a reliable tool for screening a database of virtually designed sialic acid analogues for hemagglutinin inhibitors.

    In this study fragment-based drug design is combined with molecular docking simulation technique, to design databases of virtual sialic acid (SA) analogues with new substitutions at C2, C5 and C6 positions of SA scaffold. Using spaces occupied by C2, C5 and C6 natural moieties of SA when bound to hemagglutinin (HA) crystallographic structure, new fragments that are commercially available were docked independently in all the pockets. The oriented fragments were then connected to the SA scaffold with or without incorporation of linker molecules. The completed analogues were docked to the whole SA binding site to estimate their binding conformations and affinities, generating three databases of HA-bound SA analogues. Selected new analogues showed higher estimated affinities than the natural SA when tested against H3N2, H5N1 and H1N1 subtypes of influenza A. An improvement in the binding energies indicates that fragment-based drug design when combined with molecular docking simulation is capable to produce virtual analogues that can become lead compound candidates for anti-flu drug discovery program.

    AIM: To assess the knowledge, attitudes and practices of primary health care providers regarding the identification and management of domestic violence in a hospital based primary health care setting.

    METHOD: A survey of all clinicians and nursing staff of the outpatient, casualty and antenatal clinics in University Malaya Medical Centre using a self-administered questionnaire.

    RESULTS: Hundred and eight out of 188 available staff participated. Sixty-two percent of the clinicians and 66.9% of the nursing staff perceived the prevalence of domestic violence within their patients to be very rare or rare. Majority of the clinicians (68.9%) reported asking their patients regarding domestic violence 'at times' but 26.2% had never asked at all. Time factor, concern about offending the patient and unsure of how to ask were reported as barriers in asking for domestic violence by 66%, 52.5% and 32.8% of the clinicians respectively. Clinicians have different practices and levels of confidence within the management of domestic violence. Victim-blaming attitude exists in 28% of the clinicians and 51.1% of the nursing staff. Less than a third of the participants reported knowing of any written protocol for domestic violence management. Only 20% of the clinicians and 6.8% of the nursing staff had ever attended any educational program related to domestic violence.

    CONCLUSION: Lack of positive attitude and positive practices among the staff towards domestic violence identification and management might be related to inadequate knowledge and inappropriate personal values regarding domestic violence.

    Needlestick injury has been recognized as one of the occupational hazards which results in transmission of bloodborne pathogens. A cross-sectional study was carried out among 136 health care workers in the Accident and Emergency Department of two teaching hospitals from August to November 2003 to determine the prevalence of cases and episodes of needlestick injury. In addition, this study also assessed the level of knowledge of blood-borne diseases and Universal Precautions, risk perception on the practice of Universal Precautions and to find out factors contributing to needlestick injury. Prevalence of needlestick injury among the health care workers in the two hospitals were found to be 31.6% (N = 43) and 52.9% (N = 87) respectively. Among different job categories, medical assistants appeared to face the highest risk of needlestick injury. Factors associated with needlestick injury included shorter tenure in one's job (p < 0.05). Findings of this study support the hypothesis that health care workers are at risk of needlestick injury while performing procedures on patients. Therefore, comprehensive infection control strategies should be applied to effectively reduce the risk of needlestick injury.

    The acute toxicity of standardized extract of Orthosiphon stamineus was studied in Sprague Dawley rats. The rats were administered a single dose of 5000 mg/kg body weight (BW) orally on Day 0 and observed for 14 days. There were no deaths recorded and the animals did not show signs of toxicity during the experimental period. The effect of the extract on general behavior, BW, food and water intake, relative organ weight per 100 g BW, hematology and clinical biochemistry were measured. All the parameters measured were unaffected as compared to the control. The acute toxicity LD(50) was estimated to be > 5000 mg/kg BW.

    Some Malaysian scholars believe that the theoretical basis and models of intervention in Islamic counseling practices in Malaysia are deficient and not eminently identified. This study investigated and describes the nature of current Islamic counseling practices including the theories and modules of Islamic counseling that are been practiced in Malaysia. This qualitative research has employed data that mainly consist of texts gathered from literatures and semi-structured interviews of 18 informants. It employed grounded theory analysis, and the result shows that most of the practitioners had applied integrated conventional counseling theories with Islamic rituals, references, interventions and ethics. Some had also applied Islamic theories and modules formulated in Malaysia such as iCBT, al-Ghazali counseling theories, Cognitive ad-Deen, KBJ, Prophetic Counseling and Asma Allah al-Husna Counseling Therapy.

    The spread of human immunodeficiency virus (HIV) infection and the resulting acquired immune deficiency syndrome (AIDS) is a major health concern in many parts of the world, and mathematical models are commonly applied to understand the spread of the HIV epidemic. To understand the spread of HIV and AIDS cases and their parameters in a given population, it is necessary to develop a theoretical framework that takes into account realistic factors. The current study used this framework to assess the interaction between individuals who developed AIDS after HIV infection and individuals who did not develop AIDS after HIV infection (pre-AIDS). We first investigated how probabilistic parameters affect the model in terms of the HIV and AIDS population over a period of time. We observed that there is a critical threshold parameter, R0, which determines the behavior of the model. If R0 ≤ 1, there is a unique disease-free equilibrium; if R0 < 1, the disease dies out; and if R0 > 1, the disease-free equilibrium is unstable. We also show how a Markov chain Monte Carlo (MCMC) approach could be used as a supplement to forecast the numbers of reported HIV and AIDS cases. An approach using a Monte Carlo analysis is illustrated to understand the impact of model-based predictions in light of uncertain parameters on the spread of HIV. Finally, to examine this framework and demonstrate how it works, a case study was performed of reported HIV and AIDS cases from an annual data set in Malaysia, and then we compared how these approaches complement each other. We conclude that HIV disease in Malaysia shows epidemic behavior, especially in the context of understanding and predicting emerging cases of HIV and AIDS.

    Objectives: Periodontitis is a chronic disease which remain undiagnosed and untreated without proper examination and referral to specialist clinic for further management Therefore, this study was conducted to evaluate the pattern of referrals to Universiti Teknologi MARA (UiTM) Periodontal Specialist Clinic. Materials and methods: A total of 176 periodontal cases referred to UiTM Periodontal Specialist Clinic in year 2011 and 2016 were identified and patient’s referral forms were collected. The data obtained were the referred cases from undergraduate student clinics, other specialist clinics, UiTM primary dental care clinic and private dental clinics. Descriptive data analysis was conducted using frequency distribution by SPSS. Chi square analysis was used to evaluate the association of source of referral, diagnosis and reason for referrals to Periodontal Specialist Clinic. Results: There was increased referral cases to Periodontal Specialist Clinic in 2016 (86.9%) compared to 2011 (13.1%). Most referral to Periodontal Specialist Clinic were received from faculty’s undergraduate student clinic in both 2011 and 2016 (46%), followed by other specialists (27.3%), primary care clinic (25.6%) and private practice (1.1%). 96% of cases were referred for intervention by periodontist as more than half of the cases were referred for the non-surgical periodontal treatment. Chi square analysis showed the association between source of referral and reason for referral was statistically significant (p value=0.000). Conclusion: Proper periodontal screening in all patients and necessary referral to specialist clinic is crucial to prevent undiagnosed periodontal disease.

    Breast cancer is the most common cancer among Malaysian women. Nonetheless, in Malaysia there is a marked geographical difference in the incidence of breast cancer with advanced stage of presentation. The breast clinic in Kuala Lumpur Hospital diagnosed approximately 150 to 200 new cases of breast cancer a year. This number, however, represents only 12.0% to 15.0% of all breast disease seen annually in Kuala Lumpur Hospital. Between 1998 and 2001, of a total of 774 cases of newly diagnosed breast cancer in Kuala Lumpur Hospital, only 5.0% (40/774) were impalpable breast cancers. The peak age group for the three major ethnic distributions (Malay, Chinese, and Indian) ranged from 40 to 49 years. The mean tumor size at presentation was 5.4 cm (range: 1-20 cm), and the advanced stage of breast cancer is observed to be highest among the Malay ethnic group. Although it appears that the incidence of breast cancer in Malaysia is lower than in the developed countries, the difference may be attributable to the difficulty in getting accurate statistics and to underreporting of cases. Nonetheless, from the available data, it is clear that breast cancer continues to be the most common cancer among Malaysian women. The strongly negative social-cultural perception of the disease, made worse by the geographical isolation of many rural areas, accounts for the delayed diagnosis and the often advanced stage of disease at presentation. A prospective population-based study is called for to verify the demographic patterns of breast cancer, particular in Malaysia and other developing countries. The findings of such a study may have implications for future breast screening programs and for facilitating the understanding of differing risks of breast cancer among women around the world.

    Aesthetic or cosmetic dentistry is one of the main areas of dental practice. Increasing demands of patients for
    aesthetics has resulted in the development of several techniques for restoring the anterior teeth. Composite
    resin restorations have become an integral part of contemporary restorative dentistry and can be called “star
    of minimal invasion” due to its conservative concepts. The direct composite veneering allows restoring the
    tooth in a natural way and preservation of sound tooth structure when compared to indirect restorations.
    Before placement of direct composite veneers, a proper diagnosis, available treatment options, cost of
    treatment, patient’s expectations and duration of treatment should be taken into consideration. This article
    presents three case reports of aesthetic rehabilitation of anterior teeth using direct composite with
    satisfactory outcome that mimic the natural dentition.

    OBJECTIVES: Currently, Malaysia faces great challenges in allocating adequate resources for healthcare services using a tax-based system. Therefore, Malaysia has no choice but to reform its healthcare financing system. The objective of this study is to assess Malaysian household willingness to pay and acceptance levels to the proposed National Health Financing Scheme.

    STUDY DESIGN: This is a cross-sectional study.

    METHODS: In total, 774 households from four states in Malaysia completed face-to-face interviews. A validated structured questionnaire was used, which was composed of a combination of open-ended questions, bidding games and contingent valuation methods regarding the participants' willingness to pay.

    RESULTS: The study found that the majority of households supported the establishment of the National Health Financing Scheme, and half proposed that a government body should manage the scheme. Most (87.5%) of the households were willing to contribute 0.5-1% of their salaries to the scheme through monthly deductions. Over three-quarters (76.6%) were willing to contribute to a higher level scheme (1-2%) to gain access to both public and private healthcare basic services. Willingness to pay for the National Health Financing Scheme was significantly higher among younger persons, females, those located in rural areas, those with a higher income and those with an illness.

    CONCLUSION: There is a high level of acceptance for the National Health Financing Scheme in the Malaysian community, and they are willing to pay for a scheme organised by a government body. However, acceptance and willingness to pay are strongly linked to household socio-economic status. Policymakers should initiate plans to establish the National Health Financing Scheme to provide the necessary financing for a sustainable health system.

    Background: Medication therapy management (MTM) service provides set of clinical activities to optimize therapeutic outcomes for patients. It requires the collaboration between patient, pharmacist and other healthcare providers to ensure safe and effective use of medicines. The objective of the current study was to assess Hospital Pulau Pinang pharmacists' knowledge, attitude and practice on MTM service.

    Methods: A self-administrated validated survey was carried out among all pharmacists working at Hospital Pulau Pinang.

    Results: A total of 93 pharmacists out of 130 (71.5%) were included in the study (61.3% between the age of 20-30 years old, 74.2% female, 68.8% Chinese, 88.2% holding bachelor's degree and 48.4% working in medication therapy adherence clinic and outpatient pharmacy). Majority of pharmacists had a high level of knowledge and positive attitudes regarding MTM service. All pharmacists agreed that MTM service could improve the quality of health services and most pharmacists were interested in providing MTM service (92.5%). Moreover, 95.7% were interested in acquiring more information about MTM service. About the barriers that might affect MTM service implementation, the most common barriers identified by pharmacists were lack of training (88.2%), need of high budget to implement MTM service (51.6%) and lack of time (46.2%).

    Conclusions: Overall, the research findings provide some insights about the Hospital Pulau Pinang pharmacists' knowledge, attitude and practice regarding MTM service. Majority of pharmacists agreed and showed their interest towards the implementation of MTM service.

    Study site: pharmacists working at Hospital Pulau Pinang.

    Introduction: It is mandatory that every blood donor must have their haemoglobin (Hb) values measured before blood donation. High Hb may indicate an underlying hidden pathological condition. The aim of this study is to investigate the occurrence of the JAK2 V617F gene mutation in blood donors with erythrocytosis. Methods: A cross-sectional study was conducted over a nine-month period involving blood donors with high pre-donation Hb. A total of 45 blood donors with total white cell (TWC) > 12.0x 109/l, platelet > 450x109/ l and Hb > 18g/dL were subjected to JAK2 V617F gene mutation analysis. Samples were collected and analysed for haematological tests and detection of JAK2 V617F mutation. Results: From a total of 2238 blood donors, 175 blood donors had high haemoglobin value. Samples from forty-five of these donors were then analysed for JAK2 V617F using allele-specific polymerase chain reaction (PCR). The prevalence of blood donors with erythrocytosis was 7.8%. All samples were negative for the JAK2 V617F mutation. Conclusions: Erythrocytosis can be relative or absolute and the different causes can be distinguished on the basis of clinical signs and symptoms. An absence of the JAK2 V617F mutation cannot by itself excludes the diagnosis of polycyhaemia vera (PV) since erythrocytosis is the single clinical feature that sets PV apart from other types of myeloproliferative neoplasm (MPN). Further study is required for the detection of other gene mutations that activates the JAK-STAT signalling pathway that could be identified in JAK2 V617F-negative MPN patients.

    BACKGROUND: Primary care doctors are responsible to provide smoking cessation intervention (SCI) to smokers in a community. This study aimed to assess the SCI practice among primary care doctors themselves and its associated factors.

    METHODS: This cross-sectional study was conducted from July to October 2016. All the 140 doctors in 12 public primary care clinics in Kuala Lumpur were invited to participate in this study. However, only 122 doctors (females, 82.8%) completed the self-administered questionnaire that assessed their demography, clinical experience, SCI practice and its barriers, self-efficacy in delivering and knowledge on smoking and SCI.

    RESULTS: Only 42.6% of the doctors had good SCI practice. Almost all doctors assessed the smoking status of their patients (98.4%) and advised them to quit (98.4%). However, lesser proportions of the doctors followed up the practice of patients (50.0%), taught smokers on various methods of quit smoking (46.70%) and discussed about the barriers and resources to quit prior to the quit date (27.9%). Less than one-fourth of the doctors were confident in providing SCI. Although 69.7% had previous training in SCI, many felt they had inadequate knowledge (56.6%) and skills (47.5%). Only 11.5% of doctors thought their previous training was enough. Having higher level of knowledge on smoking and SCI was significantly associated with good SCI practice [adjusted Odds Ratio (95% Confidence Intervals): 1.21 (1.02, 1.43), p=0.026].

    CONCLUSION: The SCI practiced by the primary care doctors in this study was sub-standard, particularly in assisting smokers to quit and arranging follow up. Low self-efficacy in providing SCI was also common. These inadequacies may be due to poor knowledge and skills, which needs to be improved through effective clinical training.

    The ways in which airline performance depends on the economic situation and internal operation are well established in the literature. One of the contextual factors that may change the nature of these relationships is firm age. As such, the aim of this study is to investigate the moderating influence of firm age on airline performance outcomes. Thirty airline companies from the Asia Pacific region were selected, and relevant data from 2006 to 2011 were collected. It can be deduced that company experience or firm age can help in taking control of the relationship between the constructs; thus, this measurement acts as a moderator in the research model.
