    BACKGROUND:
    Smoking is a major public health problem, especially in Iraq. There is very little information had been documented regarding smoking risk factors and quit intention among Iraqi smokers.

    OBJECTIVES:
    The main objectives of this study are to determine smokers' knowledge and perception about smoking health risks; and to determine smoking behavior and quitting intentions among Iraqi smokers; as well as to predict the factors that may associate with quit intentions.

    METHODS:
    A cross-sectional study was conducted at the outpatient clinic in Tikrit Teaching Hospital, Tikrit City, Iraq. Adult smokers who are smoking cigarette everyday and able to communicate with the researcher were invited to participate in the study. A self-administered questionnaire was used to collect data from 386 participants.

    RESULTS:
    This study showed that smokers had low awareness about some risk effects of smoking such as lung cancer in nonsmokers (30.1%), impotence in male smokers (52.6%), premature ageing (64%), and stroke (66.3%). In addition, the high score of knowledge and perception was significantly associated with quitting intention.

    CONCLUSION:
    Smokers' knowledge and perception regarding smoking health effects were low, especially in terms of secondhand smokers. Many efforts needed from health policy-makers and health care professionals to disseminate information about the risks of smoking and health benefits of give up smoking.

    INTRODUCTION: This review describes standardized ergonomics assessment based on pen-and-paper observational methods for assessing ergonomics risk factors.

    OBJECTIVE: The three main objectives are to analyze published pen-and-paper observational methods, to extract and understand the risk levels of each method and to identify their associated health effects.

    METHODOLOGY: The authors searched scientific databases and the Internet for materials from 1970 to 2013 using the following keywords: ergo, posture, method, observational, postural angle, health effects, pain and diseases. Postural assessments of upper arms, lower arms, wrists, neck, back and legs in six pen-and-paper-based observational methods are highlighted, extracted in groups and linked with associated adverse health effects.

    RESULTS: The literature reviewed showed strengths and limitations of published pen-and-paper-based observational methods in determining the work activities, risk levels and related postural angles to adverse health effects. This provided a better understanding of unsafe work postures and how to improve these postures.

    CONCLUSION: Many pen-and-paper-based observational methods have been developed. However, there are still many limitations of these methods. There is, therefore, a need to develop a new pen-and-paper-based observational method for assessing postural problems.

    DNA methylation, a major regulator of epigenetic modifications has been shown to alter the expression of genes that are involved in aspects of glucose metabolism such as glucose intolerance, insulin resistance, β-cell dysfunction and other conditions, and it ultimately leads to the pathogenesis of type 2 diabetes mellitus (T2DM). Current evidences indicate an association of DNA methylation with T2DM. This review provides an overview of how various factors play crucial roles in T2DM pathogenesis and how DNA methylation interacts with these factors. Additionally, an update on current techniques of DNA methylation analysis with their pros and cons is provided as a basis for the adoption of suitable techniques in future DNA methylation research towards better management of T2DM. To elucidate the mechanistic relationship between vital environmental factors and the development of T2DM, a better understanding of the changes in gene expression associated with DNA methylation at the molecular level is still needed.

    INTRODUCTION: Workplace health promotion is important in the prevention of non-communicable diseases among employees. Previous workplace health programs have shown benefits such as lowered disease prevalence, reduced medical costs and improved productivity. This study aims to evaluate the impact of a 6-year workplace health promotion program on employees' blood pressure in a public university.

    METHODS: In this prospective cohort study, we included 1,365 employees enrolled in the university's workplace health promotion program, a program conducted since 2008 and using data from the 2008-2013 follow-up period. Participants were permanent employees aged 35 years and above, with at least one follow up measurements and no change in antihypertensive medication during the study period. Baseline socio-demographic information was collected using a questionnaire while anthropometry measurements and resting blood pressure were collected during annual health screening. Changes in blood pressure over time were analyzed using a linear mixed model.

    RESULTS: The systolic blood pressure in the hypertension subgroup decreased 2.36 mmHg per year (p<0.0001). There was also significant improvement in systolic blood pressure among the participants who were at risk of hypertension (-0.75 mmHg, p<0.001). The diastolic blood pressure among the hypertensive and at risk subgroups improved 1.76 mmHg/year (p<0.001) and 0.56 mmHg/year (p<0.001), respectively. However, there was no change in both systolic and diastolic blood pressure among participants in the healthy subgroup over the 6-year period.

    CONCLUSION: This study shows that continuing participation in workplace health promotion program has the potential to improve blood pressure levels among employees.

    The role of insulin-like growth factors (IGF) in prostate cancer development is not fully understood. To investigate the association between circulating concentrations of IGFs (IGF-I, IGF-II, IGFBP-1, IGFBP-2, and IGFBP-3) and prostate cancer risk, we pooled individual participant data from 17 prospective and two cross-sectional studies, including up to 10,554 prostate cancer cases and 13,618 control participants. Conditional logistic regression was used to estimate the ORs for prostate cancer based on the study-specific fifth of each analyte. Overall, IGF-I, IGF-II, IGFBP-2, and IGFBP-3 concentrations were positively associated with prostate cancer risk (Ptrend all ≤ 0.005), and IGFBP-1 was inversely associated weakly with risk (Ptrend = 0.05). However, heterogeneity between the prospective and cross-sectional studies was evident (Pheterogeneity = 0.03), unless the analyses were restricted to prospective studies (with the exception of IGF-II, Pheterogeneity = 0.02). For prospective studies, the OR for men in the highest versus the lowest fifth of each analyte was 1.29 (95% confidence interval, 1.16-1.43) for IGF-I, 0.81 (0.68-0.96) for IGFBP-1, and 1.25 (1.12-1.40) for IGFBP-3. These associations did not differ significantly by time-to-diagnosis or tumor stage or grade. After mutual adjustment for each of the other analytes, only IGF-I remained associated with risk. Our collaborative study represents the largest pooled analysis of the relationship between prostate cancer risk and circulating concentrations of IGF-I, providing strong evidence that IGF-I is highly likely to be involved in prostate cancer development.

    Pulmonary embolism (PE) is the principal preventable cause of in-hospital deaths. Prevalence of PE in Asians is uncertain but undoubtedly underestimated. Asians and Caucasians have similar non-genetic risk factors for PE, and there is mounting evidence that PE affects Asians much more commonly than previously supposed; incidence, especially among high-risk patients, may approach that in Caucasians. Furthermore, PE incidence in Asia is increasing, due to both increased ascertainment, and also population ageing and growing numbers of patients with predisposing risk factors. Despite being warranted, thromboprophylaxis for high-risk patients is not routine in Pacific Asian countries/regions. There also appears to be scope to implement venous thromboembolism (VTE) management guidelines more assiduously. Anticoagulants, primarily heparins and warfarin, have been the mainstays of VTE management for years; however, these agents have limitations that complicate routine use. The complexity of current guidelines has been another barrier to applying evidence-based recommendations in everyday practice. Updated management approaches have considerable potential to improve outcomes. New oral anticoagulants that are easier to administer, require no, or much less, monitoring or dose-adjustment and have a favourable risk/benefit profile compared with conventional modalities, may offer an alternative with the potential to simplify VTE management. However, more information is required on practical management and the occurrence and treatment of bleeding complications. Increasing recognition of the burden of PE and new therapeutic modalities are altering the VTE management landscape in Pacific Asia. Consequently, there is a need to further raise awareness and bridge gaps between the latest evidence and clinical practice.

    OBJECTIVES: This study explored the demographic characteristics of hepatitis C patients in the Kota Setar (KS) district, Kedah, Malaysia, the prevalence of intravenous drug use (IVDU) as a risk factor among these patients, and the associations between IVDU and demographic characteristics.

    METHODS: Retrospective data pertaining to 713 patients from January 2009 to December 2013 were retrieved from hospital and disease notification records for analysis. The risk factors for hepatitis C virus (HCV) infection were grouped into IVDU and non-IVDU risk factors for analysis using multiple logistic regression.

    RESULTS: Of the hepatitis C patients included in this study, the most common age group was 31 to 40 years (30.2%), and male patients (91.2%) made up the overwhelming majority. Ethnic Malays constituted approximately 80.4% of the patients, and IVDU was the main risk factor (77.8%) for HCV infection. Multiple logistic regression showed that male patients were 59 times more likely to have IVDU as a risk factor for HCV infection. Single patients were 2.5 times more likely to have IVDU as a risk factor. Patients aged ≥71 years were much less likely than patients aged ≤30 years to have IVDU as a risk factor for HCV infection.

    CONCLUSIONS: IVDU was found to be an important risk factor for HCV infection among patients in the KS district. The factors associated with IVDU included age, sex, and marital status. Appropriate preventive measures should be developed to target the groups in which IVDU is most likely to be a risk factor for HCV infection.

    Diet is one of the major factors that can exert a majorly influence on colorectal cancer risk. This systematic review aimed to find correlations between various diet types, food or nutrients and colorectal cancer risk among Asian populations. Search limitations included Asian populations residing in Asia, being published from the year 2008 till present, and written in the English language. A total of 16 articles were included in this systematic review. We found that red meats, processed meats, preserved foods, saturated/animal fats, cholesterol, high sugar foods, spicy foods, tubers or refined carbohydrates have been found by most studies to have a positive association with colorectal cancer risk. Inversely, calcium/dairy foods, vitamin D, general vegetable/fruit/fiber consumption, cruciferous vegetables, soy bean/soy products, selenium, vitamins C,E and B12, lycophene, alpha-carotene, beta-carotene, folic acid and many other vitamins and minerals play a protective role against colorectal cancer risk. Associations of fish and seafood consumption with colorectal cancer risk are still inconclusive due to many varying findings, and require further more detailed studies to pinpoint the actual correlation. There is either a positive or no association for total meat consumption or white meats, however their influence is not as strong as with red and processed meats.

    Clinical experience with extensively Drug Resistant tuberculosis (XDR-TB) has not been reported in Malaysia before. We describe the clinical characteristics, risk factors, progress and therapeutic regimen for a healthcare worker with XDR-TB, who had failed therapy for multidrug resistant TB (MDR TB) in our institution. This case illustrates the risk of TB among healthcare workers in high TB-burden settings, the importance of obtaining upfront culture and susceptibility results in all new TB cases, the problem of acquired drug resistance developing during MDR-TB treatment, the challenges associated with XDR-TB treatment regimens, the value of surgical resection in refractory cases, and the major quality of life impact this disease can have on young, economically productive individuals.

    This study was done to determine the clinical course, cause and outcome of Acute Flaccid Paralysis (AFP) in children. All AFP cases (< 15 years) in the children's ward of Khulna Medical College Hospital (Bangladesh) were recorded, investigated and followed up to sixty days as a part of passive surveillance. Main outcome variables were vulnerable age group, vaccine status, predominant limb involvement, clinical variants, virus isolation and residual paralysis. Thirty-four children with AFP were admitted in hospital in the last three years with the highest number (14) in 1998. The majority of children belonged to the age group 5-9 years with a male female ratio of 1.3:1. Nearly one third of the cases were either partially vaccinated or not vaccinated at all. The lower limbs bore the brunt of paralysis excepting a few (14.7%). Clinically, Guillain Barre Syndrome was the commonest (47.1%) followed by encephalomyelitis. No poliovirus was isolated from these cases. Residual paralysis was observed in four out of ten cases who returned for follow up. AFP will continue to occur even after eradication of poliomyelitis and Guillain Barre Syndrome is the most important clinical entity for this.

    The risk factors and modes of death following acute diarrhoeal illness in children admitted to University Hospital, Kuala Lumpur between 1982 and 1997 were studied retrospectively. Among 4,689 cases of acute gastroenteritis admitted, ten deaths were noted. The case mortality rate was 2.1/1000 admissions. All deaths were infants below one year, with eight females and two males. Acute renal failure and acute pulmonary oedema were common preceding events. Female sex, infants less than twelve months, the presence of hyper or hyponatraemia and moderate to severe dehydration on admission were risk factors for deaths.

    Venous thromboembolism (VTE) is thought to be a rare occurrence in Asian patients. The clinical features of VTE are elusive and the disease often unsuspected. Objective testing such as the duplex ultrasound scans and pulmonary imaging are necessary as clinical diagnosis alone is inaccurate. Fatality can occur in untreated patients not suspected of the disease as shown by our post-mortem studies. Indeed VTE is one of the leading causes of maternal mortality in Singapore. There is a rising trend in the incidence of VTE in Asia. Initial studies found an incidence of about 3 per 10,000 hospital admissions in Hong Kong and Malaysia in 1988 and 1990, respectively; rising to 8 and 15.8 per 10,000 hospital admissions in Singapore 1992 and 2000, respectively. The major risk factors for developing deep vein thrombosis (DVT) in our patients are immobilisation, surgery and malignancy. While Factor V Leiden mutation and mutation at position 20,210 in the prothrombin gene are found to be extremely rare in Chinese, the rest of the thrombophilia has not been formally studied. Studies in Singapore reported rates of 3% to 7% of DVT after general surgery, 9.7% after hip surgery and 14% after total knee replacement surgery. It is difficult to compare with studies from other centres because of differences in patient selection and diagnostic criteria. Studies in Singapore showed that the use of prophylactic low molecular weight heparin completely abolished the occurrence of DVT for patients undergoing total knee replacement and colorectal surgery without an increase in bleeding complications. In conclusion, VTE is not an uncommon problem here. Major acquired risk factors do not differ from the Caucasian populations. VTE is a preventable disease and a better understanding of its epidemiology, patient-risk factors and biological factors will allow better management of this condition.

    Otitis media with effusion (OME) is a very common condition seen in children, and is the commonest cause of hearing loss in an infant. It is also a fairly common condition encountered by the family practitioner, and often the family practitioner is the first doctor the parents bring the child to. Otitis media with effusion is a simple condition but, if left undiagnosed or untreated, can lead to preventable long-term consequences. Hence, a high index of suspicion is necessary, early and accurate diagnosis, prompt treatment, with close follow-up is of essence. The epidemiology, aetiological factors, clinical presentations, diagnosis, various medical and surgical options, cost-effectiveness of therapy and the impact of OME on the child's development are discussed.

    Fertility and gynaecological malignancies have an important relationship. A clear inverse relationship exists between family size and the incidence of ovarian and endometrial cancer. Current methods of fertility control have an influence on subsequent development of various gynaecological malignancies. A slightly increased risk of breast cancer has been reported in current users and those who had used hormonal contraceptives (OCs) within 10 years; this risk declined with time and disappeared after 10 years. Women who started OC before age 20 had a higher relative risk; the disease did not spread beyond the breast in the majority. Most studies found OC to reduce the risk of ovarian and endometrial cancer. The relative risks of squamous cell carcinoma and adenomatous carcinoma of the cervix have been reported to be 1.3 and 1.5, respectively in ever-users of OCs; however, the aetiology of cervical cancer is multifactoral. Several reports suggest the beneficial effect of tubal ligation and breast feeding in reducing the risk of ovarian cancer. Therapy of gynaecological malignancies may have an influence on subsequent fertility. Amenorrhoea developing after treatment of hydatidiform mole may be due to choriocarcinoma, recurrent mole or a normal pregnancy. Choriocarcinoma can also develop after a partial mole. The risk of fetal teratogenicity from chemotherapy is present only if conception occurs during or immediately following the treatment cycles. Fertility is not impaired following chemotherapy. Successful pregnancies have occurred in women who have had widespread GTD including cerebral metastases. In the young patient with gynaecological malignancy preservation of fertility is possible. Fertility-sparing surgery may be safe in early ovarian epithelial cancers and even in advanced germ cell tumours. Recently, the fertility-sparing surgery of radical trachelectomy and pelvic lymphadenectomy has been carried out for early invasive cervical cancer in young women. Gynaecological cancer occurring in pregnancy is uncommon; it presents the clinician with a difficult situation to manage. In most instances the cancer is treated as though the patient is not pregnant; the timing and mode of delivery needs individualization. The overall prognosis for breast cancer complicating pregnancy is poor. Survival in cervical cancers diagnosed antepartum is similar to the non-pregnant patient. Ovarian cancer in pregnancy has a good prognosis because of the early stage at diagnosis.

    This study was the first assessment of a nationwide risk approach system to antenatal management introduced to Malaysia in 1989. Three rapid, record-based surveys on three different study groups were conducted to determine risk factor prevalence, accuracy of risk assignment, action after risk assignment and the relationship of risk level and place of delivery. The most frequent risk factors were short birth interval, high parity and first pregnancy. Accuracy of risk assignment was highest at the lowest levels of risk and poorest at the highest levels. Women at the lowest levels of risk were more likely to be seen by a doctor than women at highest risk. These was a trend to deliver in hospital, rather than at home, as level of risk increased; but many women at high risk still delivered at home. Recommendations are made on modifications to the system prior to future evaluation.

    One hundred and two patients attending the systemic lupus erythematosus (SLE) clinic of the Department of Medicine, Universiti Kebangsaan Malaysia, were studied retrospectively to determine their survival rates and causes of death. There were 21 deaths. The 1, 5, and 10 year survival rates were 93%, 86% and 70% respectively. There was a bimodal pattern of mortality with more patients dying in the first 2 years or after 5 years of disease. Infection was the direct cause of death in 52% and contributed to a further 19% of deaths. Patients with lupus nephritis had a higher relative risk (RR) of death (RR = 4.34, p < 0.02) although there was no significant increase in risk with any particular histological type on biopsy. Cerebral lupus (RR = 3.08, p < 0.001) and methylprednisolone treatment (RR = 6.24, p < 0.001) were also associated with increased risk of death. Increased awareness of infection and earlier use of antibiotic therapy may improve survival of patients suffering from SLE.

    To examine the risk factors of HIV type-I infection among male drug addicts in Malaysia, a case-control study was conducted on inmates, aged 20-40 years, at a drug rehabilitation centre in January, 1994. Stratified random sampling was performed. A total of 87 cases and 261 controls, chosen by frequency matching for age and ethnicity, answered self-administered questionnaires. About 59.8% of the subjects administered drugs intravenously and of these, 71.2% shared needles. Practices significantly associated with HIV infection were needle-sharing (OR = 8.53; 95% CI = 3.36-5.52), sexual relationship with prostitutes (OR = 3.70; 95% CI = 2.10-6.56), homosexuality (OR = 4.05; 95% CI = 1.49-11.11) and non-condom use while having sex with prostitutes (OR = 2.27; 95% CI = 1.05-4.97).
