The purpose of this study is to compare the road conditions (straight road, winding road and hill road) with the hand grip pressure force and muscle fatigue for male and female drivers. Ten subjects were participated in this study. The force measurement and electromyography (EMG) responses were taken and evaluated by using the tactile grip and pressure measurement (Grip System) and Electromyography (EMG) device. The result indicated that the winding road produced more muscle fatigue and high hand grip pressure force compared than downhill road, hill up road, and straight road for both male and female subjects. The result compared the muscle fatigue and hand grip pressure force between the first 15 minutes and last 15 minutes of driving activity. The muscle fatigue increasingly high for the last 15 minutes compared to first 15 minutes. However, the hand grip pressure forces become high during the winding road for first 15 minutes of driving session. The muscle fatigue become high as the hand grip pressure force value is high. Furthermore, the male drivers exert higher hand grip pressure force and higher muscle fatigue compared to female drivers. This study can be used as a guideline for the future studies, primarily in solving the driving fatigue problem among the Malaysian’s drivers. The method of this study could also be used for early detection of driver fatigue issues. Indirectly, the findings could reduce the number of car accidents in Malaysia.

Driving activity has become more important as this medium being practical, it is also cheaper and faster in connecting human from one to another place. However, in some occurrence, it can cause accidents as they become fatigued while driving. Driver fatigue is one of the top contributors to the road accidents and can be dangerous as other road safety issues such as drink driving. Worst is, there are no laws regulating driver fatigue. Therefore, the main purpose of this study is to develop the regression model of apsychophysical factor for drivers’ fatigue which can predict the relationship between the process input parameters and output responses. The study was participated by ten subjects. The heart rate was taken and recorded using heart rate monitor. Design Expert 8.0.6 software was used for the regression analysis. The modeling validation runs werewithin the 90% prediction intervals of the developed model and the residual errors were less than 10%. The R 2 value is 0.9400 whichmeans that the linear regression line passed exactly through all points. The significant parameters that influenced the heart rate were also identified.The parameters are time exposure, type of road, and gender.

Chromium is an essential mineral and cofactor for insulin that plays an important role as hormone that helps in the blood sugar regulation. Kelantanese were known as sugar-based food consumer. Farmers have high risk of health problem because of exposure to pesticide and sugar-based food intake can give an effect on the level of chromium. The objective of this research was to study the status of chromium among farmers exposed to pesticides and fertilizer in Kelantan. This was a cross-sectional study that was done at Bachok and Pasir Puteh, Kelantan. Respondent were 113 farmers who had been exposed to pesticides or fertilizer for not less than one year. Subjects were interviewed to obtain information on their demographic data by using validated knowledge, attitude and practice (KAP) questionnaire. Nails and hair chromium levels were analyzed by using acid digestion method and Inductively Coupled Plasma Mass Spectroscopy (ICP-MS). Results showed that 81.4% were male while 18.6% were female. Farmer’s chromium level in nails (125.82 ± 47.81 μg/L) and hair (39.63 ± 5.70 μg/L) were very much lower when compared with standard value in nails (6200 μg/L) and hair (100-2500 μg/L). No signifi cantly differences (p > 0.05) were found between chromium level according to gender, age, level of pesticide exposure, dietary chromium intake and blood glucose. Chromium levels in nails and hair of farmers who smoke was signifi cantly lower (p < 0.05) than non-smoking farmers. As a conclusion, the level of chromium among farmers in Bachok and Pasir Puteh, Kelantan are lower than normal reference and farmers should stop smoking because smoking can lower the chromium level

Introduction: We recently developed a scoring system for diagnosis of acute appendicitis. This study prospectively evaluates the Raja Isteri Pengiran Anak Saleha Appendicitis (RIPASA) score for the diagnosis of acute appendicitis in patients presenting to the Accident & Emergency department or the Surgical wards with right iliac fossa pain. Materials and Methods: From November 2008 to April 2009, consecutive patients presenting to the Accident & Emergency department or the surgical wards with right iliac fossa pain were recruited for the study. The RIPASA score was applied but the decision for radiological investigations or emergency appendicectomy was made based on clinical judgement. Receiver operating curve (ROC), sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the new scoring system were derived. Ethical approval for the study was obtained from the Medical & Health Review Ethics Committee. Results: Within six months, 144 consecutive patients with a mean age of 29.5 ± 13.3 yrs were recruited to the study. Ninety-eight patients underwent emergency appendicectomy of which 79 were confirmed histologically for acute appendicitis. The observed negative appendicectomy rate was 19.4%. The optimal cut-off threshold score from the ROC was 7.5, with a sensitivity of 97.5%, specificity of 81.8%, PPV of 86.5%, NPV of 96.4% and a diagnostic accuracy of 91.8%. The predicted negative appendicectomy rate was 13.5%, which is a 5.9% reduction from the observed rate of 19.4% (p=0.3). Conclusion: The RIPASA score is a more suitable appendicitis scoring system developed for our local settings with a population that is reflective of our region in South-east Asia and has high sensitivity, specificity and diagnostic accuracy.

Pesticide exposure can lead to low trace elements levels in human body. Trace element plays important role in body metabolism. The aim of this study was to study the levels of selenium, zinc and chromium among paddy farmers who expose to pesticide in Wilayah I, MADA, Perlis. This cross sectional study involved 70 males paddy farmers and 57subjects living in fisherman village as control group who were aged between 21 to 80 years old. Subjects were interviewed to obtain information on their demographic data by using validated questionnaire. Subjects also were examined for their blood pressure and glucose level. Selenium, zinc and chromium levels were analyzed by using acid digestion method and Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Results showed that selenium levels in hairs (5.11 ± 17.05 μg/L) and nails (4.92 ± 2.17 μg/L) were significantly (p < 0.05) lower compared to selenium levels in hairs (15.67 ± 10.59 μg/L) and nails (6.67 ± 2.81 μg/L) in control group. Chromium levels in hairs (31.83 ± 15.17 μg/L) and nails (87.64 ± 23.30 μg/L) were also significantly lower (p < 0.05) compared to chromium levels in hairs (85.19 ± 56.90 μg/L) and nails (99.36 ± 56.89 μg/L) of control group. However there were no significant different (p>0.05) between all trace element levels and duration of pesticide exposures. In conclusion, levels of trace elements were lower in nails and hairs of paddy farmers than fisherman community group

Higher education institutions face major challenges in managing the impact of the COVID-19 pandemic. The risk of exposure from the community poses a threat to campus staff and students. This study describes epidemiological characteristics of suspected COVID-19 cases among a public university’s students and staff. This is a retrospective review on data collected from the institute’s COVID-19 Preparedness and Respond Centre, located at the main campus in Kota Kinabalu, the capital city of Sabah from mid-January to April 2020. Incidence rate was calculated, and epidemiological information retrieved from interviews and relevant documents. The majority of suspected COVID-19 cases were staff (57.1%) with incidence rates higher among males (IR=40.2/1,000 population) and those working in the frontline (IR=39.6/1,000 population). Suspected COVID-19 cases were mostly related to occupation (37.3%) and social contacts (27.3%). Student cases were largely related to household (38.1%) and during travel (33.3%). One positive COVID-19 case was reported of out of the 161 suspected cases (0.6%) in the institution. An operational team must be set up to conduct situational analysis and integrate management with other departments. Suspected COVID-19 cases must be quarantined and monitored on a daily basis. A high index of suspicion and effective containment of suspected cases will prevent spread of the virus among students and staff.

Introduction: The objective of this study was to assess parental acceptance and factors that influenced their perceptions towards the use of dental therapists in providing treatment to children in private dental practice settings. Methods: A cross-sectional study was conducted on randomly selected parents of 11-year-old schoolchildren in Selangor using a self-administered structured questionnaire. The survey consisted of three sections: socio-demographic characteristics, dental service utilisation and parental acceptance towards dental therapists in providing seven types of preventive and operative dental procedures. Results: The response rate was 83.1%. Overall, most parents regarded dental therapists providing dental care to their children in private dental care settings as acceptable, particularly on preventive treatment, namely ‘seeking advice on oral hygiene care' (87.8%) and ‘applying topical fluoride' (83.2%). In the multivariate analysis, younger parents and those who had preferences over private sectors were most likely to accept at least four dental procedures to be rendered to their children by dental therapists. Overall, respondents who were younger (OR = 1.40, 95% CI = 1.62, 1.92), lived in urban locality (OR = 1.77, 95% CI = 1.28, 2.45) and had a recent dental visit (OR = 1.51; 95% CI = 1.10, 2.07) were more likely to have an overall positive perceptions towards dental therapists. Conclusion: Most parents regarded dental therapists providing care to their children in private dental settings as acceptable and this was associated with their age, place of residence and past dental experiences.
