Low-molecular-weight heparins (LMWHs) are antithrombotic agents utilised in the treatment of acute coronary syndromes. They have been shown to be more effective than unfractionated heparins (UFHs) in reducing ischeamic events, which include death, myocardial infarction (MI) and urgent revascularisation. Enoxaparin is one of the products of LMWHs. Its safety and efficacy has been proven in the ESSENCE and TIMI IIB studies. This study was carried out to identify risk factors that may affect bleeding complications associated with the use of enoxaparin for non-ST-elevation MI (NSTEMI) or unstable angina (UA) in Universiti Kebangsaan Malaysia Hospital (HUKM). This observational, longitudinal study was conducted on patients who were admitted to the Coronary Care Unit (CCU), Coronary Rehabilitation Ward (CRW), Medical 1 and Medical 2 wards at HUKM and initiated on enoxaparin for NSTEMI/UA from 22nd of March until 22nd of April 2004. A total of 40 patients were included in the study with median age of 65 years, male to female ratio of 3:1, diagnosed with NSTEMI (55%) and UA (45%). 45% of patients developed an episode of bleeding and among them 83.3% (15 patients) characterised by haematuria. Higher percentages of women (80%) and those with creatinine clearance of < 30ml/min (100%) had incidence of bleeding as compared to men (50%) and those with creatinine clearance = 30 ml/min, respectively (p < 0.05 for both parameters). Age, enoxaparin dose and duration of therapy, smoking and concomitant aspirin/ticlopidine therapy did not significantly affect the incidence of bleeding. In conclusion, renal impairment and gender were associated with bleeding in relation with the use of enoxaparin that may require dose adjustments.
Falls are the most common injury causing death or long term disability particularly among children. This study aimed to identify the risk factors of the unintentional injuries due to falls in children aged less than five years in Yemen. This cross sectional study enrolled a total of 439 children under five years old from the emergency department of 6 hospitals in Sana'a city. Multistage sampling was used to select six hospitals from public and private sectors in Sana'a city. Face to face interviews were conducted by using a structured questionnaire. Simple logistic regression and multiple logistic regression were used in the analysis. The prevalence of falls among children under five years old was 21.2%. In the multivariate analysis, factors associated with falls among children were young mother (aOR= 0.9, 95% CI 0.81-0.91), working of mother (aOR= 4.5 95% CI 2.40-7.65), frequent family social gatherings (aOR= 2.7, 95% CI 1.54-4.61), number of children at home (aOR= 2.6, 95% CI 1.43-4.64), chewing khat by father (aOR= 2.4, 95% CI 1.38-4.10), presence of staircase in the house (aOR= 2.1, 95% CI 1.24-3.70), number of rooms at home (aOR= 2.2, 95% CI 1.17-3.99) and disabled children (aOR= 3.3, 95% CI 1.20-9.27). In the study, socio-economic and cultural factors such as family gathering and chewing khat were associated with home fall injury among children under 5 years old in Yemen. Health promotion program should take place to reduce the occurrence of fall injury.
Night work and rotating shift work are found to be detrimental to the health of workers. A cross sectional analytical study was conducted among the employees of a public medical centre in Kuala Lumpur. A total of 380 employees participated in the health screening and questionnaire survey. The majority of the respondents were Malays, females, and with mean age of 49 years old. The shift workers persistently had higher but non-significant proportions of being overweight/obesity and unhealthy clinical indicators such as systolic and diastolic blood pressure, fasting blood glucose and lipid profile except waist circumferences and HDL-cholesterol. There were also slightly more shift workers diagnosed with diabetes mellitus, hypertension or coronary heart disease (p>0.05). Although the present study could not provide established evidence for a relationship between shift work and cardiovascular risks, this could serve as a pilot study for future studies in this area.
Background: Hypertension is estimated to cause4.5% of the global disease burden. The prevalence of hypertension in Malaysia is 32.2%.
Objective: To determine the prevalence of hypertension and its associated risk factors in two rural communities in Penang, Malaysia.
Methods: This cross sectional study was conducted among all consenting residents aged 18 years and above from two villages in Penang. Besides the baseline demographic information, blood pressure was measured using a manual sphygmomanometer according to the American Heart Association Guidelines.
Results: 50 out of 168 people were hypertensive, giving a prevalence rate of 29.8%. 50.0% of those found with hypertension were undiagnosed and 48.0% of those who were diagnosed with hypertension had uncontrolled blood pressure. Logistic regression analysis showed that age, history of alcohol consumption and BMI were found to be independently associated with hypertension.
Conclusions: Age, education level, alcohol consumption and BMI are important risk factors associated with the prevalence of hypertension among the villagers. These risk factors are comparable to those reported in National Health and Morbidity Survery 2006 in Malaysia.
Down Syndrome (DS), is a complex genetic disease resulting from the presence of 3 copies of chromosome 21. It is the most common autosomal abnormality among live births and the most commonly recognized genetic cause of mental retardation. The only well established risk factor for DS is advanced maternal age. The Human Genome Center , University Sains Malaysia, Kelantan has been carrying out cytogenetic studies in DS patients. Here we, report the karyotype pattern of Down Syndrome patients in correlation with maternal age, among referral cases to our Center.
Introduction: Medical school expected to be a time of personal development, achievement, and well-being. However, research shows that there are many negative effects on students’ mental health due to the current educational process. Objective: This research aimed to determine the prevalence and risk factors of depression, anxiety, and stress among medical students of a private medical university in Malaysia. Method: Cross sectional study was conducted using self-administered questionnaires including socio-demographic factors, DASS-21 and MSSQ-40 questionnaires. Result: Prevalence of stress, anxiety, and depression were 46.9%, 76.2% and 60.2% respectively. Multiple logistic regression analysis showed that academic related stressors were only associated with stress [adjusted OR 1.78, 95% CI (1.23, 2.58), p=0.002]. Group activities related stressors were significantly associated with stress [adjusted OR=1.45, 95%CI (1.20, 1.75), p
Children with epilepsy are at increased risk of behavioral problems and psychiatric disorders compared with the general population and those with other chronic illnesses. Depression and anxiety disorders are the most common and require further attention because they carry the risk of reduced quality of life and have far reaching consequences in later life. The wide range of prevalence quoted in the literature reflects methodologic differences. Risk factors are often multifactorial and include illness severity, coexisting morbidity, and psychosocial factors. Diagnosis remains a challenge, as the presentation is heterogenous and age related. This is complicated by epilepsy issues and associated comorbidity that hamper the use of standardized assessment tools. Multimodal treatment involving psychotherapy and antidepressant therapy currently represents the best approach. The mental health needs of these children are largely unmet; increased awareness and better research are required to determine best practices.
Introduction: Pre-pregnancy care is an important strategy in prevention of adverse maternal and fetal health as well as continuity of good child care. In multi-ethnicity country such as Malaysia there are many cultural, religion and beliefs related to certain life stages.
Methodology: A cross sectional study was conducted among the Indian ethnic group to assess the prevalence and factors associated with pre-pregnancy care. A study was conducted in Taman Manickavasangam Hulu Langat Selangor among the age group of 18-45 year old women.
Result: There were 90 respondents participated in self administered questionnaires. There were 65 respondents (72.2%) married, 24 (26.7%) single and one widow (1.1%). Using a scoring method of analysis (high and low) showed that 55 (61.1%) have high score in knowledge on pre-pregnancy care. The prevalence of pre-pregnancy care practice showed that 63 (70%) scored as high practice. Using correlation analysis showed that there was a significant association between the practice score and increasing age (P=0.03). However, only history of previous pregnancy showed a significant association with the pre-pregnancy care practice and no association found between the practice and knowledge score.
Conclusion: Prepregnancy care helps in screening risk factors of women before conception. This will help in prevention of adverse effect on maternal and foetal. Giving awareness on the importance of having prepregnancy care screening may help women to continue practicing good antenatal care.
Non-communicable diseases are raising much concern in Malaysia due to changing lifestyles which is parallel to the economic development. Intervention program like community health screening (CHS) allows early detection, prevention and reduction of chronic diseases and its risk factors. This study aimed to assess the obesity level, risk factors for chronic diseases and blood cholesterol level among the Malaysian public. A health screening program was conducted on April 2012 at Sungai Pinang township, in the state of Pulau Pinang, Malaysia. A convenient sample of the general public was recruited. Screening tests consisted of measurements of blood pressure, body mass index (BMI), body fat percentage, visceral fat accumulation (VFA) and blood cholesterol. Chi-square analysis was used to determine the difference between prevalence of obesity among subjects with different age groups and gender. Out of 76 recruited subjects, 23.7% had systolic blood pressure of 140 mmHg or greater and 7.9% had diastolic blood pressure of 90 mmHg or greater. Approximately 51% of the subjects were obese (BMI ≥ 27.5 kg/m2). Body fat percentage was high in 63.6% and 63.0% of male and female subjects, respectively. High VFA (≥15) was found in 19.8% of subjects. There were three newly discovered hypercholesterolemia cases (total cholesterol ≥ 5.2 mmol/L). Counselling was given during the health screening program to help the public to take necessary measures to reduce risk factors while preventing complication resulting from these chronic diseases. In conclusion, prevalence of obesity found to be high in the present screened population.
This study aimed to review the risk factors and clinical outcomes of patients undergoing pars planar vitrectomy (PPV) for breakthrough bleeding (BTB) from age related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV). We performed a retrospective review of medical records of 346 patients operated by the vitreoretinal unit at Universiti Kebangsaan Malaysia Medical Centre (UKMMC), Kuala Lumpur, Malaysia from January 2008 - June 2011. We found eight eyes of 8 patients with AMD/IPCV-related BTB who underwent PPV. Mean age of patients was 64.4 years (range 41-80 years) with 5 males. Five were Chinese. Duration of symptoms ranged from days to months. Four patients were on anti-coagulants. Two had history of prior photodynamic therapy. There were five cases of PCV, of which three were macular in location. All three cases of AMD were macular. Intraoperative intravitreal ranibizumab injection was given in three cases and two had combined vitrectomy and cataract extraction. All cases reported improvement in visual acuity with four cases achieving 6/60 or better post operatively including two cases of extramacular PCV achieving 6/9 vision. Mean follow-up was 60 weeks. Postoperative complications included retinal tear and detachment in one case, reattached on reoperation. Six patients had a history of hypertension including one individual with stroke. Our small series indicates a predominance of Chinese individuals with BTB. Usage of anticoagulants and hypertension may be a predisposing factor. Better visual prognosis occurs with extramacular lesions which tend to be of PCV type.
Background: Metabolic Syndrome is a major concern for the general population but more so for depressed patients. While it is well established that it is highly prevalent among patients who are depressed, none of the local studies identified the factors contributing to the syndrome.
Objective: This study aimed to determine the rate of metabolic syndrome and its associated factors (socio-demographic, clinical features and lifestyle risk factors) in depressed patients.
Methods: A cross sectional study was conducted on patients with major depressive disorders (MDD) attending psychiatric outpatient clinic in Universiti Kebangsaan Malaysia Medical Centre (UKMMC), a teaching hospital in Kuala Lumpur. A total of 72 outpatients who fulfilled the selection criteria were informed to fast prior to blood taking. The diagnosis of MDD was made based on Diagnostic Statistical Manual Version IV (DSM-IV) while the metabolic syndrome diagnosis was made using the International Diabetes Federation (IDF) criteria based on the patients’ waist circumference, blood pressure, serum glucose level and lipid profile.
Results: The rates of metabolic syndrome was 37.5% (n = 27). The results showed significant associations between metabolic syndrome and race (p = 0.043), illness duration (p = 0.043) and pre-existing hyperlipidaemia (p = 0.032). Interestingly, lifestyle factors like physical activity (p = 0.762), dietary intake (p = 0.671), severity of depression (p = 0.161) and the different types of medications (p = 0.242 to 1.000) were not found to significantly associated with metabolic syndrome among the study sample.
Conclusions: Metabolic syndrome was found to be disproportionately high among depressed patients. Two significant factors associated with this syndrome were race and long duration of depression (ten years or more). This study suggests that early screening and identification can be beneficial to be incorporated in the management of depression in anticipation of future complications.

Objective: This study aimed to determine the prevalence of obesity among patients with schizophrenia and its association with the demographic profile. Methods: This is a cross sectional study. Subjects were selected using systematic sampling. Patients attending the out patient psychiatric clinic, Hospital Universiti Kebangsaan Malaysia, who fulfilled the criteria and able to give consent were included in this study. Diagnosis of schizophrenia was made using Structured Clinical Interview (SCID) for DSM-IV. Demographic profiles of the patients were obtained and anthropometric measurements were measured and classified according to Body Mass Index (BMI) and Waist Circumference (WC) of Asian population. Results: A total of 97 patients were included. The prevalence of overweight (BMI: 23.0- 27.4 kg/m2) was 39.2% (n=38), and the prevalence of obesity (BMI: >27.0 kg/m2) was 35.1% (n=34). BMI was higher among non-Chinese (Malay and Indian, p=.03) and those who had low total household income (p=.03). Sixty-two patients (63.9%) had high WC, which was associated with male (p=.003) and non-Chinese (p=.03). Conclusions: Obesity is highly prevalent among patients with schizophrenia. The risk factors for obesity include male, non-Chinese and those with low total income. The high WC among non-Chinese and male patients suggests that they are at a higher risk of developing obesity-related physical illnesses. These findings support that obesity is a common critical issue among schizophrenic patients, and it warrants serious clinical interventions.

We aimed to report the first case of anorexia nervosa in a young Malaysian Malay homosexual man with underlying borderline personality disorder and major depression. Patient and parents were interviewed. The Structured Clinical Interview for DSM IV was used to generate Axis-I diagnosis. The Hamilton Depressive Rating Scale was used to assess the severity of depression. His parents had marital discord. His father was overinvolved. Regarding anorexia nervosa, he had 163 cm height, 46kg weight and a body mass index (BMI) of 17 kg/m2. His four limbs had multiple scratch marks. Laboratory test results showed anemia, leukocytosis and hypoalbuminemia. Family pathology, borderline personality disorder and homosexuality could be the risk factors of anorexia nervosa in this patient.
Aims : The review was to determine the prevalence of needlestick injury especially among health care personnel and to determine the score of knowledge and compliance to the Standard Universal Precaution.
Method : Twelve theses were reviewed from year 1996 to 2007 of Master in Community Health Science, Master in Community Health and Postgraduate Diploma in Occupational Health of Community Health Department Universiti Kebangsaan Malaysia Medical Center involving of 1645 respondents of health care personnel, support staff and student of nursing and medical. Eleven studies were cross sectional design and only one study was retrospective.
Results : Respondents were dominated by female (74.6%) and Malay ethnicity (65%), as young as 19 years old to 56 years old of age. Majority had received Hepatitis B vaccination (79.4%) but only 37.1% had completed the 3 doses regime. The incidence of episodes of needle stick injury among health care personnel was double (53.7%) compared to final year medical students (20.9%). Needle stick injuries did not occur at random as there were a few health care personnel injured repeatedly. Those who had higher mean or median score for compliance to Standard Universal Precaution were non case of needlestick injury. Work practices had been highlighted in few studies of being risk factors for needlestick injury such as blood withdrawing related activities. Other risk factors were job category, predictive factor for compliance to Standard Universal Precaution, risk perception and training.
Conclusion : Even though the review could not extrapolated to general population of healthcare personnel but it gave some illustrated pictures to what had happened in small clustered locations. Episodes of needle stick injury was 53.7% for past 12 years, it was double in comparison to final year medical students in year 2001. 13.2% were injured repeatedly. The score of knowledge was more the 50% of range but compliance to Standard Precaution made differences in being cases or non cases among respondents. The seroconversion status till date was unknown.
Students in tertiary level education are mostly young adults that are transiting from the teenage years to adulthood. Since there is less restriction as compared to their teenage years, university and college students might involve in risky behaviours that may affect their health, social and academic performance. Thus, the purpose of this study is to investigate and identify the differences of health risk factors and health promoting behaviour that have been practiced by students in Malaysia. A cross sectional study was conducted using closed-ended questionnaires distributed to university and college students via emails. The results showed that 77.0% students claimed they have no health problem. However 49.0% of the non-medical students did not know whether they have normal BMI. Among the medical students, 62.0% rarely do physical exercise even though most are seriously concern about their fat consumption (95.0%). Only 30.0% of the total students have awareness of wearing seat belt. For health promoting behaviour, 33.0% of female students have never perform breast self examination (BSE), while 65.0% of male students have never perform testicular self examination (TSE). These findings confirmed that there are differences in health risk factors and health promoting behaviour that have been practiced by the students.
Introduction: The purpose of this study was to determine the prevalence of defaulters of immunization, and their associated risk factors among children age 12 to 24 months. Materials and Methods: A cross-sectional study was conducted in all government's maternal child health clinics in District of Kota Kinabalu, Sabah. Data was collected using a standardised questionnaire from July to November 2006. Results: The prevalence rate for defaulting immunization was 16.8% from the 315 respondents. Bivariable analysis showed various significant factors associated with defaulters such as mother’s employment status, family mobility, transportation and cost. Nonetheless, multivariable analysis showed only mother’s age, mother employment status and family size were the significant predictors for defaulting immunization. Immunization that had the highest rate of defaulters was DPT–OPV booster dose (56.6%), followed by MMR immunization (43.4 %) and
DPT-Hib/OPV and Hep B third dose (37.7%).Conclusion: Employed mothers with bigger family size should be more closely monitored and advised to reduce the chance of defaulting on the immunization. Health promotion activities also should focus to these groups of mothers.
Introduction: The aim of this study is to determine the prevalence of otitis media with effusion (OME) in Malaysian children between three months to twelve years of age and to identify the risk factors associated with it.
Materials and methods: This is a cross-sectional study consists of 153 children selected by stratified random sampling method. Parents of these children were interviewed with a structured questionnaire. Clinical examination, including otoscopic examination and tympanometry was performed for each child.
Results: The prevalence of OME was 18.3%. There was no statistical significant relationship between OME and gender, race, household size, attendance to daycare center, breast feeding, and exposure to passive smoking, allergy, and asthma.
Conclusion: The prevalence of OME is 18.3% in Malaysian children between three months to twelve years of age. Frequency of AOM is a statistically significant factor to the development of OME later in life. The different risk factors associated with OME are still controversial.
Introduction: Our objectives are to identify the incidence of hypophosphatemia and the associated risk factors. We also want to establish intravenous replacement therapy that is effective for ICU patients. Methods: A prospective observational study assessing adults admitted to ICU in between March and May 2009. All patients without baseline phosphate level and renal failure were excluded. They were evaluated for the occurrence of common risk factors. Association with independent variables that includes age, gender and BMI were verified. Evaluation of IV replacement therapy was done in the treated patients. Results: From 50 patients that were reviewed, nine were excluded. There were 66% male and 34% female with mean age 46.88±17.89. The mean ICU stay was 8.00±6.41 days. The incidence of hypophosphatemia was 29% (n=12/41). Gender and
creatinine clearance was found to be significantly different between normophosphatemia and
hypophosphatemia patients. There was no significant association for each potential risk factor and the number of risk factors (≥3) with the incidence of hypophosphatemia. Multi-linear regression analysis showed that lactate, creatinine clearance and pH were significant predictors to the serum levels. A significant difference of mean serum phosphate was seen after repletion by total dose of 10, 20 and 40 mmols in the treatment subgroups. Conclusions: The incidence of hypophosphatemia in our ICU was high and comparable to previous studies. None of the commonly reported risk factors is associated with hypophosphatemia in this studied population. Among all significant correlated variables, only pH was found to be a significant predictor for serum phosphate. Baseline phosphate level may guide the initial replacement dose to prevent delay in normalization of serum levels.
A case control study was conducted to identify the risk factors for acute lower respiratory tract infections (ALRI) in hospitalised children in Kelantan. One hun-dred and twenty children aged one month to five years hospitalised for ALRI were matched by age with 120 children as controls. Data on demography and expo-sure to putative risk factors were collected by interview-ing parents or caretakers. Anthropometric measure-ments were also carried out to assess the nutritional sta-tus of the children. For each risk factor studied, the odds ratios for exposure and disease were calculated by using univariate analysis followed by multiple logistic regression analysis to determine those factors which remained significant.
The presence of sibling(s) who coughed at home (OR 12.1, 95% CI 5.2-28.1), crowding in bedroom (OR 4.4, 95% CI 2.1-9.0), weight-for-age < 3rd percentile (OR 9.0, 95% CI 3.1-25.8), lack of breast feeding (OR 9.4, 95% CI 2.3-38.4) and incomplete immunisation (OR 4.5, 95% CI 1.7-12.1) were significant indepen-dent risk factors for ALRI. Other factors like poverty, maternal education level, male sex, low birth weight, history of atopy, family history of asthma and indoor air pollution were not associated with an increased risk of ALRI.
This study showed that poor nutritional status, inap-propriate child care practices and poor living conditions, particularly those related to crowding, predispose to ALRI in Kelantanese children necessitating hospital admission. A change in these factors may reduce the morbidity and mortality of childhood ALRI in Kelantan.
Meconium aspiration syndrome (MAS) frequently occurs in neonates born in thick meconium-stained liquor (TMSL). It continues to be a significant cause of neonatal morbidity and mortality despite aggressive approaches to intervention. This study aims to identify the perinatal characteristics of deliveries with TMSL associated with the development of MAS and to describe the outcome of those babies who developed MAS.
All newborns with TMSL born in Hospital Alor Setar, Kedah from 1 October 1998 to 30 April 1999 were prospectively studied. In the hospital, all newborns with TMSL were routinely admitted to the Special Care Nursery for observation. Relevant data regarding pregnancy, delivery, resuscitation and outcome of newborns with and without MAS were collected and analysed. The incidence of TMSL among hospital deliveries was 2.2% (95% C.I. 1.8-2.5%). Thirty-six percent (95% C.I. 28.4-44.7%) of newborns with TMSL developed MAS. Significant risk factors associated with the development of MAS were non-Malay mothers (p=0.04, OR=3.32), resuscitation by paediatric medical officers (p=0.02, OR=2.84) and direct tracheal suction during resuscitation (p=0.02, OR=2.61). The presence of non-Malay mothers or resuscitation by paediatric medical officers or direct tracheal suction during resuscitation gave a sensitivity of 88.2%, specificity of 36.7%, a positive predictive value of 44.1% and a negative predictive value of 84.6% for the development of MAS. Asphyxia, pneumothorax and persistent pulmonary hyper-tension occurred in 25.5%, 7.8% and 5.9% of the babies with MAS respectively. Mechanical ventilation was required in 51% and the mortality rate was 3.9%. In conclusion, the incidence of TMSL and MAS and the mortality rate of neonates with MAS were comparable with that in developed countries. The presence of any one of the significant risk factors had high sensitivity but low specificity for the development of MAS. Newborns were unlikely to develop MAS if all these risk factors were absent.
