It is the aim of all clinicians to accomplish biological tooth movement, which implies the use of low, continuous force. Constant unrelented search for a better wire, which can deliver optimal orthodontic force, has led to the invention of a lot of orthodontic wires such as Stainless steel, Beta Titanium, Nickel Titanium and multi stranded wires. In this study, the loading and unloading properties of 0.016 inch, 0.016x0.022 inch and 0.017x0.025 inch dimensions of stainless steel, conventional NiTi, Super elastic NiTi, and TMA arch wires were determined by means of a modified three point bending test for two inter bracket widths of 5 mm and 6.5 mm for deflection of 1 to 3 mm. The applied forces dependence on cross-sectional size differs from the linear-elastic prediction in super elastic NiTi wires. The stainless steel wires had the highest force values on all the three dimensions and cross section. On loading and unloading, TMA wires had force values in-between stainless steel, conventional NiTi and super elastic NiTi. The conventional NiTi had much lower force values compared to stainless steel and TMA and were linearly progressing compared to Super elastic NiTi. On loading and unloading the super elastic NiTi had force values in the range of conventional NiTi and had constant forces on higher deflection. The studies showed that the force value was comparatively higher in 5 mm inter bracket width than the 6.5 mm inter bracket width for all the cross section and dimension of wires.
While the prevalence of visually impaired children constitutes a small portion of the visually impaired population, it is important to determine whether the low vision services available are utilised by these children. This is important as previous studies have shown that children have a very high rate of successful low vision device use compared to adults. This was a cross sectional retrospective study. Fifty nine low vision clinic children records were evaluated. The results showed that 25.4% of the children were categorised as with moderate low vision, 30.5% with severe low vision and 40.7% were categorised as blind. The major causes of low vision were congenital cataract, congenital nystagmus, congenital glaucoma, macular degeneration and retinitis pigmentosa. Low vision rehabilitation for near work using magnifiers improved the vision of 30.5% of the low vision children. This finding suggests that 1/3 of low vision children could benefit from low vision rehabilitation. The low vision devices most commonly prescribed to the children in this study were stand magnifiers, hand-held magnifiers and spectacles. This study illustrates the key role of optometrists in the management of visual impairment in Malaysian children. It would appear that the establishment of low vision services in government hospitals using trained optometrists is a cost effective method of service delivery. Therefore more low vision children would have access to proper low vision rehabilitation and through that rehabilitation, their quality of life can be improved.

Malnutrition is common among pediatric oncology patients. Factors contributing to malnutrition include physiological abnormalities, response to the tumors and side effects of the treatment. A pilot study was carried out to determine the nutritional status of 17 pediatric oncology patients aged 4 to 12 years old in Hospital Universiti Kebangsaan Malaysia, Kuala Lumpur. The
nutritional status was assessed via anthropometric measurements and dietary intake through 3 days repeatitive 24 hours diet recall with subjects and their carers. Biochemical profiles (serum albumin and hemoglobin) were reviewed from the medical record. Through anthropometry measurements, weight and height were used to calculate Z-scores and further determine the percentile weight-for-age, height-for-age using NCHS percentile charts (WHO 1983). Frisancho’s standards (1981) were used to define malnutrition based on MUACfor- age. Underweight as determined using z scores below -2 for weight-for-age was observed in 70.6% of the subjects. Whilst, 76.5% of the subjects were classified as stunted (z score < –2) for height-for-age. Based on MUAC-for-age percentile, the sign of severe malnutrition category (<5 percentile) was observed in 35.3% of the subject and 23.6% of the subject were in the moderate malnutrition (>5 – <10 percentile). About 70.6% of the subject had low haemoglobin (< 11 g/dl) and 29.4% of the subject were hypoalbuminemia (< 35 g/dl) . Total macronutrient intake was assessed and compared with the individual requirement (Seashore 1984) for energy and protein intake were satisfactory, except for subjects in age group 10 – 12 years who achieved only 70% of the individuals requirements. As a conclusion, although food intake of the subjects was satisfactory but chronic malnutrition was prevalent. Early recognition of malnutrition is essential in order to plan for a nutritional intervention and further enhancing the quality of life.

Patient waiting time was introduced to orthodontic clinics in 2009 as a Key Performance Indicator (KPI) in the Ministry of Health Malaysia (MOH) as a measure of client satisfaction. A cross-sectional pilot study was carried out in 2009 in all four main government orthodontic clinics in Selangor. The objectives were to measure patient actual waiting time and evaluate conformance to this KPI. The sample comprised of 5,286 patients; 9.2% from Tanjung Karang, 37.1% Kajang, 29.3% Klang and 24.4% Shah Alam. There were 33.8% punctual, 44.2% early and 21.9% late patients. The mean actual waiting time (AWT) in Selangor was 30 min (SD 24.7); shortest in Tanjung Karang (16.5min, SD 15.3) and longest in Shah Alam (47.9min, SD29.6). AWT was 21.9 min (SD 17.4) for patients punctual for appointments, 40.3 min (SD 40.3) for early patients and 21.9min (SD19.8) for late patients respectively. Although the mean AWT was long for early patients, 20% of them were seen earlier than their appointment time. All four clinics complied with the MOH KPI performance target (>50%) with a mean compliance of 87.5% for Selangor. There is statistically significant difference in punctuality of patients in different clinics (p
A cross-sectional study was conducted in two hospitals in Hargeisa city to determine the job and organizational stress among nurses and doctors in ICU and its influencing factors. A universal sampling method was carried out and one hundred and twenty questionnaires were distributed among nurses and doctors working in intensive care units of two hospitals on different shift duties; morning, afternoon, night and rotation shifts. The response rate was 83.3%. Regression analysis showed that approximately 88% (adjusted R square = 0.889) of the variation in stress mean score was explained by the background variables. Experience, role overload, physical environment and marital status were significant predictors.
The study aimed to explore the perceptions towards health promotion activities among population of Penang Island,
Malaysia. The study was designed as a questionnaire based cross sectional analysis. General public from the district of
Jelutong, located in the state of Penang, Malaysia was conveniently approached for the study. Descriptive statistics
were used to ascertain demographic characteristics where as inferential statistics were employed to measure the
extent of association among study variables. Out of 480 respondents, a response rate of 82.7% was achieved. The study
cohort was dominated by females (63.0%) and majority of the participants belonged to Malay ethnicity (88.1%). One
hundred and seventy two (43.3%) never attended a health promotional campaign and mentioned lack of time and
transport as potential barriers. Among those who attended such activities, one third was satisfied with the benefits of
health campaigns. Approximately 90% of the participants demanded accessible locations, common language as mode of
communication and complete medical checkups with professional advice at health promotional campaigns. General
public can encouraged to participate in the health promotion activities by considering their priorities before designing
a health promotion program. This will help in targeting and achieving the goal “health for all”.
The information on job strain among crane operators in Malaysia is lacking. The aim of this study was to determine the prevalence and contributing factors of job strain among crane operators working in port container terminals. A cross sectional study was carried out at a port container terminal in Malaysia. Data was collected using validated self-administered questionnaires, which consisted of the Job Content Questionnaire (JCQ), and the Depression, Anxiety, and Stress Scale (DASS-21). All crane operators in the selected terminal participated in the study. Data was analyzed using SSPS version 19. Two-hundred- and-forty crane operators participated in the study.. The prevalence of job strain determined from the JCQ was 43.8%. Job strain was significantly associated with psychological job demand, decision latitude, anxiety, physical isometric loads and muscle ache. The prevalence of job strain in this study was high. There is an urgent need to recognize the existence of this problem among crane operators by their respective management. Implementation of comprehensive stress management programs are recommended to reduce job strain among these workers.
Introduction: Undergraduate medical education should be broad-based, holistic, integrated and should promote a framework for the development of higher order cognitive skills like communication, professionalism and teamwork to prepare the student for a life-long challenging medical career. Recent calls for a competency-based medical education require, in addition, competency in clinical and procedural skills prior to graduation. This study investigates how often opportunities exist for medical students to perform four common ward procedures prior to graduation.
Method: A prospective cross-sectional study to assess the opportunities a medical student have in performing four common ward procedures, comprising intravenous cannulation, nasogastric tube insertion, urinary catheterisation and chest tube insertion, in a State General hospital in Malaysia was done.
Results: A medical student has sufficient opportunity to perform only intravenous cannulation prior to graduation. He has a remote chance to insert a urinary catheter and is unlikely to have the opportunity to insert a nasogastric tube or insert a chest tube prior to graduation.
Conclusion: Although competency in clinical skills and procedural skills prior to graduation are desirable, this is increasingly difficult to achieve due to shortage of clinical material, teachers to supervise, the large numbers of medical students and house officers, the short time spent on the main disciplines and the failure of many universities to invest heavily in skills laboratories staffed by full time clinicians. The calls to introduce competency-based medical education in undergraduate medical education, particularly in procedural competence, should take into account the challenges in delivery and the realities in the hospitals today. This is necessary to avoid demoralising students who are unable to achieve their quota of procedures through no fault of theirs.

Objectives: The aim of this study is to validate the Malay version of the Aggression Questionnaire (AQ) for the purpose of the future study related to aggression. Furthermore, the study seeks to identify types of aggression hold by the female inmates.
Methods: A cross-sectional study was designed involving 90 Malaysian female prisoners. The analyses include descriptive analysis, confirmatory factor analysis, and reliability testing. After one-week interval, a test-retest was conducted.
Results: The preliminary analysis confirmed that factor analysis was appropriate for the Malay-translated version of the AQ. The four factors structure was assessed but the factor loadings are remarkable different from the original versions. The total Cronbach's alpha coefficients is very high (α= 0.91). The Pearson's correlation however is low (r = 0.48) but acceptable for the instrument. Reliability of the subscales and the factors were also found satisfactory. Consequently, anger and hostility were identified as the most common types of aggression among the participants, followed by verbal aggression. In contrast, physical aggression was the least scored type of aggression.
Conclusion: The Malay-translated version of the AQ was found to be valid and reliable to be used in future studies.
Introduction: Self-awareness and reflective-skill are important components of personal and professional development of medical students.
Objective: The objective of this study was to determine whether self awareness and reflective skill could be improved by direct teaching intervention.
Method: This was a cross sectional intervention study conducted among 75 third year medical students of UKM Medical Centre Malaysia in 2010. Malaysian Emotional Quotient Inventory (MEQI) was used to measure self-awareness and reflective writing scripts were used to measure the reflective skills of the respondents before and after teaching intervention. Experimental group comprised of 30 students while the control group constituted the rest 45 students selected randomly. The factors contributing to self awareness with gender and learning styles were determined.
Result: There was no significant improvement observed in self-awareness of the respondents but reflective skills was significantly improved (p=0.007) following intervention. A non-significant relationship between self-awareness and gender (p=0.588) as well as self-awareness and learning styles (p=0.435) was also noticed.
Conclusion: It is concluded that intervention programs improved students' reflective skills but not their self-awareness. Effectiveness of the intervention programme is an important factor. Continuous effort should be focused to train students in an effective way in order to be more self-reflective, self-regulative as well as self-corrective, to ensure a high level of personal and professional development in their daily practices.
Objective: To determine the perception of medical students towards mentor-mentee system in Faculty of Medicine and Health Sciences of UNIMAS. Method: It was a cross-sectional study involving all 104 second year and 80 fifth year medical students. A self-administered questionnaire consisting of socio-demographic details, general perceptions on mentor-mentee system, academic support, personal development, and emotional and psychological support was distributed. The data was analysed using the SPSS version 19. Result: Majority of the subjects had a positive outlook towards the mentor-mentee system with a range of 45.6% to 57%. Three of the top rated perceptions were ‘mentor analyses mentee’s examination results and provides constructive feedback’, ‘mentor advises how to improve academic performance’, and ‘mentor gives encouragement and support for the challenges faced’ (66.8%, 68.0% and 62.9% respectively). Pre-cinical medical students had significantly better perception on mentor-mentee system than clinical students (p≤0.002) while those with non-clinician mentors significantly had better perceptions than those with clinician mentors (p≤0.003) on the system. No significant difference was found between the perceptions of males and females for all components (p=0.234 to 0.722). Conclusion: The mentor-mentee system was found to be successful as more than half of the respondents had posititve perception on the system and its aspects. However, pre-clinical students benefited more compared to clinical students, which reflects the need to look at the support given to clinical students. It was recommended that future studies should incorporate the perceptions of mentors.
Psychological stress among undergraduate students is associated with poor academic results, physical ill-health and psychiatric disorders. The objectives of the study were to determine the prevalence of psychological stress and its associated factors among undergraduate students attending a health programme in a local university. This is a cross-sectional study among undergraduate students attending a health programme in a local university. The 12-item General Health Questionnaire (GHQ-12) was used to determine the presence of psychological stress at a cut-off point of 4 and above. Analysis was conducted to determine any association between gender, ethnicity, year of study in the university, recent health-seeking contact with a doctor, and psychological stress among the participants. The prevalence of psychological stress among undergraduate students attending a health program in a Malaysian University was 49.3%. There was no significant association with any of the socio-demographic factors studied (p>0.05). The prevalence of psychological stress in this study was significantly high, and irrespective of gender, ethnicity, year of study in the university, and recent health-seeking contact with a doctor. Hence, the findings of this study show that it may be a useful strategy to integrate such health programs regularly in activities of colleges and universities, with the aim of promoting mental health and wellness among the students.
Quality nursing care has a great impact on patient satisfaction. Quality nursing care is perceived by the post cardiac surgery patient, as the degree of physical, emotional and spiritual needs that have to be fulfilled while hospitalisation. The objective of this study was to identify factors in quality nursing care that determine post cardiac patient satisfaction. This single cross-sectional descriptive study using ‘NURSQUAL’ instrument consisted of four elements; technical competence, information giving, assurance and empathy to measure patient satisfaction with quality nursing care. It consisted of four research questions with 33 items to measure the four elements. Between January to March 2005, 52 post cardiac surgery patients from Institute Jantung Negara (IJN), who fulfilled the inclusion criteria were recruited for this study. There was a significant difference between technical competence, information giving, assurance and empathy with patient satisfaction with p value < 0.05. The element of assurance made the strongest statistically significant unique contribution to the prediction of patient satisfaction with a p value < 0.05.
The objective of this study is to determine the prevalence of dysmenorrhoea, its associated factors and its effects on school activities among adolescent girls in a secondary school in a rural district of Selangor, Malaysia. This is a cross-sectional study conducted in a public secondary school. A stratified random sampling of 300 female students (12 to 17 years old) from Form one to Form five classes were selected. A self-administered questionnaire consisting of 20-items was used to collect sociodemographic and menstrual data. Pain intensity for dysmenorrhoea was measured by numerical rating scale. The prevalence of dysmenorrhoea was 62.3%. It was significantly higher in the middle adolescence (15 to 17 years old) age group (p=0.003), girls with regular menstrual cycle (p=0.007) and a positive family history (p
This study was conducted to determine types of educational needs among stroke patients admitted to Hospital Universiti Sains Malaysia. Stroke patients (n = 41) were conveniently recruited from Medical and Surgical Ward between September to December 2012. Data were obtained using semi-guided administered questionnaires and from the medical reports. Patients were given adequate time to complete the lifestyle history and educational needs on stroke with researcher’s assistance. Instrument on the educational needs consisted of five themes including general information on stroke, management of risk factors, treatments of stroke, rehabilitation and post-stroke problems and post-stroke diet management. Findings indicated majority of the stroke patients were female (58.5%), between 56 to 65 years old (39.0%) and diagnosed with ischemic stroke (68.3%). Patients had history of hypertension (85.4%), diabetes (46.3%), hyperlipidemia (29.3%), ischemic heart disease (22.0%) and atrial fibrillation (2.4%). Eleven of them (26.9%) were ex-smokers and many practice unhealthy lifestyle such as lack of exercise (80.5%) and prefer fried foods (68.3%). Most patients were on multiple pharmacotherapies (92.7%) to treat their medical conditions. Educational needs rated highest need to know among stroke patients were on prevention (92.7%), fi rst aid management (85.4%), complications (85.4%) and recurrence (85.4%) of stroke in general. Other concerned were about possibility of cure with drug (92.7%), range of motion exercise (82.9%), fi sh intake (78.0%), fruit and vegetable consumption (78.0%) after stroke. Findings from this study provide a baseline information on types of educational needs among stroke patients. More patient educational intervention on primary and secondary stroke prevention should be structured in hospital and community settings in the future.

A cross sectional study was conducted to determine the perception of Hospital Directors in performing clinical duties. This was done through a postal survey which was conducted covering all public hospitals in Malaysia. The majority of Hospital Directors had read the circular at the time of the study and agreed to do clinical work besides managerial duties. Before the issuance of the directive, the majority of those directors were already doing some clinical work. However they disagreed that by doing clinical work they could help overcome the problem of shortage of doctors. They agreed that the duration of 10 hours per week is suitable to do clinical duties. In term of confidence in giving curative treatment, the Hospital Directors especially those from district hospitals without specialists were confident in giving curative care to individuals. As for the clinicians, the majority felt that the implementation of the directive for Hospital Directors to do clinical work will not disrupt the clinicians' routine duties.

A cross·sectional study was done to determine the capacity of Public Health Inspectors in Selangor using a seh administered questionnaire and universal sampling, to determine the enforcement of public health legislation and its influencing factors. A total of 99 respondents from the District Health Offices and 100 respondents from the Local Health Departments participated. The level of enforcement is generally low in all the units except for the Food Unit and Sanitary and Hygiene Units. Factors influencing enforcement of Public Health Legislations are the unit where the respondents worlc and the length of service with the unit. Further analysis using multiple logistic regression, found that respondents from the Food Unit (OR ZZ; 95% C1: 7 .9-58.9 ) , being in the
U8 category (OR 5; 95% C1: l.4» 17.6), service offour years and above in the same unit (OR 6; 95% C1: 2.2»13.8) , received service rewards (OR 3; 95% C1 : 1.2· 6.9); low exposure to bribery (OR 46; 95% C1: 2.3·100.0) and offered bribes while on the field (OR 3; 95% C1: 1.02» 4.8) have higher kvel enforcement performance. Attention must be given to the enforcement organization with respect to duration of service, service awards and monitoring of bribes exposure to help develop the enforcement of public health legislations.
This survey was done to determine the knowledge, attitude and practice of preventive measures concerning Severe Acute Respiratory Syndrome (SARS) among Alor Gajah town community. The purpose of this study was to determine the knowledge level of SARS, to know their attitude towards SARS and health information provided, to know which sources that provide the best infomation about SARS and to identify the expectations and preferences of population on gaining health infomation. A cross-sectional study involving respondents age 18 and above staying in Alor Gajah town was done. The respondents were assessed using questionnaires comprising of 25 questions. A total 180 respondents had answered the questionnaire. All of them were aware of SARS with 93 .3% with high scores in the knowledge level. Furthermore, 9l .7% of respondents had high scores in their attitude towards SARS. About 98.9% of respondent got their information regarding SARS from television, and 83.9% of them believed the information given. Firty four percent choose television as the best method to convey information concerning SARS or other new emerging diseases. The knowledge and attitude of the respondents concerning SARS were good.
Purpose of the present study was to assess effect of work-family conflict (along with its four dimensions) on physical health status. In particular, we examined the mediating role of health related behaviors on the linkage between all dimensions of work-family conflict and physical health status. The current cross-sectional research was conducted among 567 women who were working in the public departments of Malaysia. Self-administrated questionnaire was used for data collection. Our findings showed that work-family conflict (along with its four dimensions) significantly and negatively correlated with physical health status. The findings from mediational analysis showed that all dimensions of work-family conflict indirectly deteriorate physical health status via increasing the chance of not using food strategies. However, our results did not support the mediating function of physical activity on the proposed relationship. Results of the current study indicated that women with greater level of work-family conflict are more likely to suffer from poor physical health status. Having multiple strategies for managing food and eating reduce the adverse effect of work-family conflict on physical health. Organizations may benefit from Family Friendly Policies (FFP) that can alleviate level of conflict and eventually avoid or decrease rate of engagement in unhealthy behavior that have detrimental effect on health status.
Caring practice is one of the three core values of Corporate Culture of Ministry of Health Malaysia, initiated in 1991. A cross sectional study was conducted to determine the extent of hospital healthcare personnel practicing the element of caring. Self-administered questionnaires were mailed to all staff working in public hospitals followed by reminder letters and telephone calls. A total of 37,267 responded out of 69,385 personnel working in the hospitals with a response rate of 53.7%. Results showed that about half of the respondents perceived that they practice caring value of the corporate culture (49.5%) and only 33.3% perceived that their colleagues practiced it. The practice of caring value was highest among clinical specialists (65.4%) and lowest among the clerks (22.1%). Nurses perceived that 40.4% of their colleagues practiced caring values while the clerks perceived only 17.0% of their colleagues practice it. In conclusion, caring value is not being well practiced by healthcare staff especially among the support staff. There is a need for further research to study the reasons for poor caring practice by healthcare personnel and develop strategies to improve the situation.
