    AIMS: The aim of this study was to evaluate the left ventricular (LV) diastolic dysfunction in rheumatoid arthritis (RA) patients without clinically evident cardiovascular manifestations and to estimate whether there is any correlation between RA disease severity and disability and LV diastolic dysfunction.
    METHODS: The study was a cross-sectional study involving 53 patients (47 female and 6 male) with RA without clinically evident heart disease and 53 healthy subjects (47 female and 6 male) who served as a control group. Both groups were matched for age and sex. Echocardiographic and Doppler studies were conducted in all patients with RA and control subjects.
    RESULTS: Of 17 cardiac parameters assessed, only two were abnormal. None of the specific cardiac diastolic dysfunction parameters were significantly different in RA patients compared to the control group. There was no significant correlation between diastolic function values in RA patients and value of Disease Activity Score 28 (DAS-28) and value of Health Assessment Questionnaires Disability Index (HAQDI). Atrial (A) wave velocity was greater in RA patients compared to the control group (0.71 [0.58-0.83] vs. 0.61 [0.51-0.71]; P < 0.04). However, interventricular relaxation time (IVRT) ([73.08 ± 9.92 vs. 70.74 ± 9.02], P = 0.207), lower E/A ratio (1.27 [1.02-1.56] vs. 1.42 [1.20-1.68], P = 0.102), diastolic dysfunction parameters according to Redfield Classification (25 [47.2%] vs. 27 [50.9%] P = 0.56), diastolic dysfunction using E/A (P = 0.321) and tissue doppler imaging (E/E') (P = 0.148) were not different.
    CONCLUSION: Prevalence of diastolic dysfunction in the rheumatoid arthritis group (47.2%) was not different from controls (50.9%). LV diastolic function had no significant correlation with RA disease severity and duration of disease.

    Introduction Anxiety and depression were known to bring detrimental outcome in patients
    with ischemic heart disease (IHD). Notwithstanding their high prevalence
    and catastrophic impact, anxiety and depression were unrecognized and
    untreated. The aim of this study was to determine the prevalence of anxiety
    and depression among IHD patients and the association of this condition with
    clinical and selected demographic factors.

    Methods This was a cross-sectional study on 100 IHD patients admitted to medical
    ward in UKMMC. Patients diagnosed to have IHD were randomly assessed
    using Hospital Anxiety and Depression Scale (HADS) and Perceived Social
    Support (PSS) Questionnaire. Socio-demographic data were obtained by
    direct interview. Fifteen percent of IHD patients in this sample were noted to
    have anxiety, fourteen percent noted to have depression while thirty two
    percent was noted to have both anxiety and depression. Patients’ age group
    and the duration of illness were found to have significant association with
    anxiety. Socio-demographic data were obtained by direct interview.

    Results Fifteen percent of IHD patients in this sample were noted to have anxiety,
    fourteen percent noted to have depression while thirty two percent was noted
    to have both anxiety and depression. Patients’ age group and the duration of
    illness were found to have significant association with anxiety. The other
    clinical and selected demographic factors such as gender, race, marital status,
    education level, occupation, co-existing medical illness and social support
    were not found to be significantly associated with anxiety or depression
    among the IHD patients.

    Conclusions In conclusion, proper assessment of anxiety and depression in IHD patients,
    with special attention to patients’ age and duration of illness should be
    carried out routinely to help avert detrimental consequences.

    The aim of this study was to determine the relationships between ApoE genotypes and ‘behavioural and psychological symptoms of dementia’ (BPSD). A cross-sectional study was conducted on 46 outpatients with dementia (aged 60 and above) and their caregivers attending the psychogeriatric clinics at Universiti Kebangsaan Malaysia Medical Centre (UKMMC) and Hospital Kuala Lumpur. Neuropsychiatric Inventory (NPI) was used for the assessment of BPSD. The patients’ blood samples were taken for Apolipoprotein genotyping after consented by the caregivers. There were more female (69.6%) and Chinese (50%) patients with a mean age of 73.7 years. ApoE ε3/ε3 was the most common ApoE allele (60.7%) and mostly found in Chinese patients. ApoE genotype was significantly associated with ethnicity (p=0.03) and marital status (p=0.01). Alzheimer disease was the most common subtype of dementia (41.3%) and the highest carrier of ApoE ε3/ε3 (30.4%). The ApoE ε4/ ε4 scored highest in BPSD median score 44 (17.5 to 90) but the relationships
    between ApoE genotypes and subtypes of dementia or BPSD scores were not significant (p=0.20; p=0.64). Agitation was the most common symptom, with delusions showing the highest scores on the NPI with no significant association to ApoE 4 allele. In conclusion, there was no significant relationship between ApoE genotypes and severity or types of BPSD in dementia patients.

    Our study aimed to examine the interplay between clinical and social predictors of future suicide attempt and the transition from suicidal ideation to suicide attempt in depressive disorders. Sixty-six Malaysian inpatients with a depressive disorder were assessed at index admission and within 1 year for suicide attempt, suicidal ideation, depression severity, life event changes, treatment history and relevant clinical and socio-demographic factors. One-fifth of suicidal ideators transitioned to a future suicide attempt. All future attempters (12/66) had prior ideation and 83% of attempters had a prior attempt. The highest risk for transitioning from ideation to attempt was 5 months post-discharge. Single predictor models showed that previous psychiatric hospitalization and ideation severity were shared predictors of future attempt and ideation to attempt transition. Substance use disorders (especially alcohol) predicted future attempt and approached significance for the transition process. Low socio-economic status predicted the transition process while major personal injury/illness predicted future suicide attempt. Past suicide attempt, subjective depression severity and medication compliance predicted only future suicide attempt. The absence of prior suicide attempt did not eliminate the risk of future attempt. Given the limited sample, future larger studies on mechanisms underlying the interactions of such predictors are needed.

    There is a large volume of published studies describing the adverse relationship between treatment non-adherence with tuberculosis treatment outcome. Non-adherence could result in increased risks of prolonged infectiousness, drug resistance, relapse cases and poor survival among tuberculosis patients. Nevertheless, few studies are to be found providing detailed on the reason of defaulting treatment among tuberculosis patients in Malaysia. Hence the goal of this paper is to find out the barriers and motivations factors that affect patients’ treatment compliance among our local tuberculosis patients. This is a qualitative study which included 12 in-depth interviews with tuberculosis non-compliance patients who were treated at Institute of Respiratory Medicine, Kuala Lumpur. All the conversations were recorded, transcribed and analysed by using thematic analysis. It was found that low knowledge, self-negative attitudes, traditional believes, negative perceptions towards health caregiver, drug side effects, stigma, financial problems, less family support and work commitments are the barriers that prevent the patients from religiously taking their anti-tuberculosis treatment. Meanwhile, factors that encourage them to continue their treatment were the believes of bad effects of the disease onto their lives and health, good relationship between patient and health caregiver and social support from people around them. In conclusion, non-adherence involved a dynamic influence of individual, socio-economic and treatment-related factors on the patients. The results presented here may facilitate improvement in the activities in promoting compliance among tuberculosis patients in the future which tailored to the patients’ specific needs.

    Introduction The extensive and intensive use of pesticides in agricultural practices has exposed farmers to various hazards resulting in varying degrees of health
    outcomes.
    Methods We conducted a cross-sectional study among paddy farmers in Sabak Bernam district, Malaysia. The objective of this study was to gather baseline information on chlorpyrifos blood level and its relationship with pesticides exposure symptoms.
    Results We detected chlorpyrifos in farmers’ blood in 7 percent of the respondents, with mean 7.29 nanogram per millilitre blood (sd 5.84 nanogram per millilitre). The percentage of farmers who experienced at least one pesticide exposure symptoms was 75 percent. However, we found no significant association between chlorpyrifos blood level and its exposure symptoms. The farmers had low scores on safe practice of pesticide use even though they have high marks on knowledge and attitude. We found no significant association between the scores on knowledge, attitude and practice on pesticide use and the chlorpyrifos blood level.
    Conclusions The presence of pesticide exposure symptoms proved that most of the farmers were exposed to hazardous effects of pesticides. Specific trainings on safe use and handling of pesticides should be given on regular basis to these farmers to ensure they are protected from hazardous effects of pesticides exposure.

    Dengue fever is an illness by arthropod-borne viral disease that become known pandemic to the most tropical countries. In 2014, Malaysia reported 108 698 cases of dengue fever with 215 deaths which increased tremendously compared to 49 335 cases with 112 deaths in 2008 and 30 110 cases with 69 deaths in 2009. This study aimed to identify the best method in determining dengue outbreak threshold for Negeri Sembilan and hopefully these methods can be standardized as it can help to send uniform messages to inform the general public and make the outbreak analysis comparable within and between countries. Methodology : Using retrospective Negeri Sembilan country dataset from 1st epid week of 2011 till the 52nd epid week of 2016. The data were split into two periods: 1) a 3-year historic period (2011–2013), used to calibrate and parameterise the model, and a 1-year evaluation period (2014); 2) a 2-year historic period (2014–2016), used to calibrate and parameterise the model, and a 1-year evaluation period (2016), used to test the model. E-dengue is a registration system for confirm case dengue by Ministry of Health. Data include details of cases, district locality, records on the outbreak and epidemiological week (Sunday to Saturday). The variables were captured using the Excel spreadsheet. Analysis method included endemic channel method, moving average or deviation bar chart and recent mean. Result: Seremban as big district and facing with heavy dengue cases, all three methods (endemic curve, current mean and moving mean) showed promising results. Meanwhile comparing with small district of Port Dickson and Tampin with fewer dengue cases and outbreak recorded, the suitable method is by using endemic channel for epidemic threshold. Conclusion: Simpler methods such as the endemic channel, recent mean and moving mean may be more appropriate in urban district. Whereas in rural or district with minimal dengue cases, Endemic Channel would be the most suitable method for epidemic threshold. However, both methods require a consistent updated graph threshold as time progress.

    The accuracy of the (13)C-methacetin breath test ((13)C-MBT) in differentiating between various stages of liver disease is not clear. A cross-sectional study of Asian patients was conducted to examine the predictive value of the (13)C-MBT in various stages of chronic liver diseases. Diagnostic accuracy of the breath test was determined by sensitivity, specificity, positive predictive value, negative predictive value, and area under the curve analysis. Seventy-seven patients (47 men/30 women, mean age 50 ± 16 years) were recruited. Forty-seven patients had liver cirrhosis (Child Pugh A = 11, Child Pugh B = 15, and Child Pugh C = 21), 21 had fibrosis, and 9 had chronic inflammation. The sensitivity and positive predictive value for liver fibrosis, cirrhosis (all stages), Child-Pugh A, Child-Pugh B, and Child-Pugh C were 65% and 56%, 89% and 89%, 67% and 42%, 40% and 40%, and 50% and 77%, respectively. Area under curve values for fibrosis was 0.62 (0.39-0.86), whilst that for cirrhosis (all stages) was 0.95 (0.91-0.99). The (13)C-methacetin breath test has a poor predictive value for liver fibrosis but accurately determines advanced cirrhosis.

    Cardiovascular disease (CVD) is a major cause of morbidity and mortality in chronic kidney disease (CKD) patients. This study aimed to determine the roles of CVD biomarkers in CKD patients. This was a case-control study which recruited consecutive patients with stage 2-4 CKD patients with and without CVD. Serum levels of highly-sensitive C reactive protein (hs-CRP), cystatin C (CysC), asymmetrical dimetylarginine (ADMA) and symmetrical dimethylarginine (SDMA) were measured. Sixty two stage 2-4 CKD patients with a mean age of 60.3 ± 10.4 years were recruited. Twenty three (37.1%) of them had CVD. Those CKD patients with CVD were older (64.1±8.0 vs 58.1± 1.1, p<0.05) and had significantly higher systolic blood pressure (139.4 ± 16.2 vs 129.4 ± 14.8 mmHg, p<0.05). Diabetic patients had 8 times (95% CI 1.25-51.77, p< 0.05) higher risk to develop CVD. CKD patients with CVD had a higher serum creatinine (185.0 ± 54.1 vs 154.1 ± 54.4 μmol/L, p<0.05), a lower estimated glomerular filtration rate (33.7 ± 12.2 vs 42.2 ± 14.5 mL/min/1.73m2 p<0.05) and a lower triglyceride levels (1.3 (1.1-1.7) vs 1.8 (1.4-2.3) mmol/L, p<0.05), compared to those without CVD. Fasting blood sugar was 7.1 ± 2.7 mmol/L in CVD group and 6.3 ± 1.6 mmol/L in non CVD group (p>0.05). There were no differences in their mean serum levels of hs-CRP, CysC, ADMA and SDMA. Risk factors including age, diabetes mellitus, hypertension and renal functions were still the most important CVD risk factors in CKD patients.

    Tuberculosis (TB) is known as a disease that prone to spatial clustering. Recent development has seen a sharp rise in the number of epidemiologic studies employing Geographical Information System (GIS), particularly in identifying TB clusters and evidences of etiologic factors. The aim of this systematic review is to determine evidence of TB clustering, type of spatial analysis commonly used and the application of GIS in TB surveillance and control. A literature search of articles published in English language between 2000 and November 2015 was performed using MEDLINE and Science Direct using relevant search terms related to spatial analysis in studies of TB cluster. The search strategy was adapted and developed for each database using appropriate subject headings and keywords. The literature reviewed showed strong evidence of TB clustering occurred in high risk areas in both developed and developing countries. Spatial scan statistics were the most commonly used analysis and proved useful in TB surveillance through detection of outbreak, early warning and identifying area of increased TB transmission. Among others are targeted screening and assessment of TB program using GIS technology. However there were limitations on suitability of utilizing aggregated data such as national cencus that were pre-collected in explaining the present spatial distribution among population at risk. Spatial boundaries determined by zip code may be too large for metropolitan area or too small for country. Nevertheless, GIS is a powerful tool in aiding TB control and prevention in developing countries and should be used for real-time surveillance and decision making.

    Introduction Cervical cancer (CC) is the second most prevalent female cancer in Malaysia. Almost 70% of its’ causal factors are attributable to oncogenic human papillomavirus (HPV) types 16, 18 and other risk factors. HPV genotypes distributions are also noted to differ by geographical area.
    Methods This was cross sectional study conducted in 2007, to determine the influencing factors of HPV positivity and prevalence of HPV infections among patients with cervical cancer in Universiti Kebangsaan Malaysia Medical Centre (UKMMC). Patients’ paraffin-embedded cervical tissues kept in the Pathology Department from 1999 to 2007 were randomly selected. A total of 81 medical records with complete information were chosen as samples and patients were contacted for consent. Tissue samples were further derived for PCR DNA for HPV genotyping. Analyses included descriptive statistics; bivariate χ2 test and correlation were used to determine relationship between factors and HPV positivity. Significance level of less than 0.05 was taken as statistically significant.
    Results Mean age of cancer diagnosis was at 52 ± 12.2 years. Women of Chinese ethnicity was the highest ethnicity to be HPV positive at 65.4% and squamous cell carcinoma was more commonly found (59.3%) compared with other types of cancers. The prevalence of HPV positivity was 92.6% with type 16 being the most common (74.1%), followed by type 33 (30.9%) and 18 (22.2%). Multiple HPV infections were a common finding at 54.3%. Factors thought to influence positivity i.e. age of intercourse, number of sexual partners, number of parity, smoking status of patients and their partners, oral contraceptive usage, presence of chronic illnesses and cancer stage were not significantly associated with HPV positivity. Increased CC severity level was not associated with increased number of HPV infections (Pearson correlation 0.58; p =0.607).
    Conclusions High HPV positivity at 92.6% was found among ICC patients. Factors thought to influence HPV positivity were not significant. The top three HPV genotypes were type 16 followed by type 33 and 18. However, local women HPV serotypes findings need to be replicated in a larger population sample.

    The purpose of this study was to compare the serum interleukin (IL)-23 levels between rheumatoid arthritis (RA) patients and healthy controls and to determine the correlation of IL-23 levels with disease activity, joint damage and functional disability in RA. Serum samples were obtained from 45 patients with RA and 45 healthy controls. The enzyme-linked immunosorbent assay method was used for quantitative analysis of IL-23. All the RA patients were assessed for disease activity based on the 28-joint disease activity score, joint damage based on modified Sharp score, and functional ability using the Health Assessment Questionnaire-Disability Index. The mean serum IL-23 level was much higher among the RA patients (24.50 ± 13.98 pg/mL) compared to the controls (5.98 ± 3.40 pg/mL; p < 0.01). There was a significant positive relationship between IL-23 levels and disease activity and questionnaire scores (p = 0.003 and 0.020, respectively). On logistic regression analysis, IL-23 levels were significantly higher in patients with moderate to high disease activity (p = 0.008, odds ratio = 1.073, 95% confidence interval = 1.019-1.130) and patients with significant functional disability (p = 0.008, odds ratio = 1.085, 95% confidence interval = 1.021-1.153). RA patients have significantly higher levels of serum IL-23. The IL-23 levels correlate well with disease activity and functional disability but not with radiographic joint damage.

    BACKGROUND: Mental health problems are affecting more children and adolescents worldwide. Individual, family and school factors are often linked with mental health problems among adolescents.

    AIM: To determine the neighbourhood factors influencing the prevalence of abnormal mental health status among adolescents in an urban population.

    METHOD: A cross-sectional study was conducted among adolescents aged 13, 14 and 16 years old from thirteen secondary schools in Kuala Lumpur using validated questionnaires. A total of 567 adolescents participated in this study.

    RESULTS: The prevalence of abnormal mental health status in this study was 4.4%. In multivariable analysis, female (OR = 1.79, 95%CI: 1.11-2.89), having divorced parents (OR = 3.53, 95%CI: 1.96-6.36), high educational stress (OR = 8.18, 95%CI: 4.25-15.75), medium educational stress (OR = 2.99, 95%CI: 1.53-5.83), whose house has been broken in before (OR = 2.02, 95%CI: 1.11-3.68) and living in a neighbourhood with low socioeconomic status (OR = 2.09, 95%CI: 1.23-3.56) were more likely to have abnormal mental health status.

    CONCLUSIONS: Neighbourhood factors were found to be significant in determining adolescents' mental health status. The findings emphasize the importance of those in the public health sector to highlight these significant neighbourhood factors to the Ministry of Housing and Local Government. Swift action needs to be taken by the Ministry to provide solutions related to the neighbourhood factors and this can contribute to improvement in the adolescents' mental health.

    Chronic non-communicable diseases are the new emerging epidemic, and they are thought to challenge only rich countries; cardiovascular disease, cancer, diabetes, and other non-communicable diseases (NCDs) are now the leading cause of death and disability in low-income and middle-income countries, where they killed almost 8 million people younger than 60 years in 2013. Therefore, there is a need to develop a valid and reliable tool to measure the beliefs that influence people’s general behaviour, and a used to measure beliefs about chronic disease perceived susceptibility. The purpose of this study was to develop and validate the use of perception questionnaire among the young Iraqi adults. A total of 200 young adults participated who are free from any chronic diseases under study, and are living in Baghdad. The questionnaire, validated by an expert’s panel, translated to Arabic language, and pretested. Analyses included descriptive statistics of all the study variables, reliability estimates, and construct validity using confirmatory factor analysis (CFA). Results showed that mean age of respondents was 30 years old, majority were males 71.5%, and EFA showed that factor loading was more than 0.4. CFA results show that Chi-square (df) = 1.213(2); p value (>0.05) = 0.297. Internal consistency reliability analysis on health-related behaviour; special practice, information seeking and perceived probability of diseases have good Cronbach’s α value of between 0.8 - 0.9. These findings revealed that validation is favourable and can be utilized on larger scale of sample to proceed with main study on chronic disease perceived susceptibility among healthy people.

    Limited studies on prevalence and risk factors of Premature Coronary Artery Disease (PCAD) were done in Malaysia, primarily on lipid profile. This cross sectional study aims to identify any changing patterns in prevalence and risk factors of Premature CAD between 2000 and 2012. From 2000 to 2012 we included 21862 patients who underwent the first Percutaneous Coronary Intervention (PCI). Analysis of risk factors was done to 1660 and 2098 patients from year 2007 and 2012 respectively. Age of less than 45 years was taken as PCAD. Data was collected from PCI database of National Heart Institute (NHI), NHI TrakCare System, and patients’ medical records. PCAD significantly decreased from 18.8% (2000) to 11.6% (2012). Malay ethnicity showed increasing trend over the years from 55.1% to 66.9%. Multiple logistic regression analysis in 2007 showed that smoking had the higher risk (AOR=2.52), followed by male gender (AOR=2.06), family history of PCAD (AOR=1.96), Indian ethnicity, (AOR=1.65), triglycerides level (AOR=1.20) and BMI (AOR=1.06). In 2012, family history of PCAD had the highest risk (AOR=2.00) followed by smoking (AOR=1.91) and BMI (AOR=1.11). There are changes in risk factors patterns of premature CAD between 2007 and 2012. Most of them are preventable at earlier stage.
