Dentistry is a noble profession where dentists often manage to bring smiles and create confidence in patients. Nonetheless, as with other medical professionals, dentists too often encounter legal suits brought against them by their patients. Legal actions against dentists are not new in Malaysia, where several actions have been litigated in court. The rise in legal actions against medical professionals including dentists is associated with the increased awareness of patient’s rights and autonomy. Legal actions can cause several repercussions on dentists such as loss of reputation, shame and anxiety. As such, it is imperative for dentists to have the basic legal knowledge on the potential legal liability that they may face should something go wrong during the course of dental treatment. This is the main crux of this paper where several dento-legal cases that have been reported in Malaysian law journals are identified and analysed. This is followed with a brief discussion on the legal issues surrounding those cases. Legal principles governing the issues identified are provided in brief so as to provide dentists with basic legal knowledge on the legal aspect of dentistry.

Autoimmune haemolytic anaemia (AIHA) is a group of disorders wherein autoantibody causes decompensated acquired haemolysis. There has been no epidemiological study of autoimmune haemolytic anaemia (AIHA) in Malaysia. This study retrospectively analysed the epidemiology of AIHA including Evan’s Syndrome in a Tertiary Haematology Centre in Malaysia. Patients diagnosed with AIHA and Evan’s Syndrome at 18 years old and above between 1 January 1994 to 1 October 2020 at the out-patient Haematology Clinic of Hospital Raja Permaisuri Bainun, Ipoh were selected. Patients’ information was retrieved from the outpatient clinic records. A total of 71 patients were included of which predominantly female. The mean age for both genders were comparable. Ethnic stratification revealed AIHA was higher in Malays followed by Chinese and Indian. Warm AIHA was most prevalent at 40.8%, compared to cold AIHA and Evan’s Syndrome (both 23.9%), and mixed AIHA (11.3%). Primary was more common than secondary AIHA followed by Evan’s Syndrome. Approximately half of the secondary AIHA and secondary Evan’s Syndrome were due to SLE. Overall, 67.6% of patients received corticosteroid only and 28.2% combined with immunosuppressant. Individuals at higher age and females have higher risk of developing AIHA and Evan’s Syndrome. The highest prevalence was seen among the Malay ethnic. Primary warm AIHA is the most common type and majority of Evan’s syndrome are secondary to autoimmune diseases.

The Malay people are the majority in Peninsular Malaysia, but their population structure and genetic profile remain poorly studied. The exposure to the origins of Malays and their sub-ethnic groups is vital prior to study about their genetic profiles as it can narrow down the haplogroups of their ancestral lineages. In this review, we have highlighted theories related to the origin of Malays from Yunnan, New Guinea, Taiwan, Sundaland, Nusantara and the theory of Bani Jawi. Nevertheless, these theories were established based on speculations without evidence. Despite the theories developed, the migration of Malay population is more prominent during the era of Malacca Sultanate. The trading activities and seafaring way of life had welcomed various ethnic groups in Peninsular Malaysia which formed a part of the Malay population today. Thus, the origin of major sub-ethnic groups of Malay population are discussed in this paper. The origin of Malay community has a key relationship with modern genomic field that was conducted through mitochondrial DNA analysis. Human identification in forensic application is tedious due to the need for sequencing whole DNA profile of Malay population. Therefore, identification of specific genetic markers for Malay population is vital to facilitate forensic investigation. We gathered data by systematically searched with Google Scholar, Pubmed, Science Direct with advanced search builder for papers titles with Malay population and genetic markers. This study shed some light on the mitochondrial DNA markers of indigenous people and Malay population in Peninsular Malaysia which can be used in future prospects.

Handwriting difficulty is one of the main issues among school children, especially for those with motor coordination issues. The aim of this systematic review is to evaluate the effectiveness of occupational therapy interventions in handwriting components for children with motor coordination issues. Current research articles were systematically searched according to the PRISMA guidelines. Two hundred and sixty-eight (n=268) research articles were identified; however, only ten (n=10) were eligible to be evaluated for this study. Studies were appraised by using McMaster Critical Review Form-Quantitative Studies. Descriptive synthesis was executed due to the heterogeneity of included studies. The review found various types of intervention conducted by occupational therapists to have a positive effect on handwriting performance components among children with motor coordination issues. Types of intervention used were visual, motor, perceptual, sensory, activity of daily living skills, training device and assistive technology and specific handwriting programs. Most handwriting intervention showed effectiveness to improve handwriting performance in motor function, visual and perceptual components. Future research should focus on homogeneity of Occupational Therapy (OT) intervention to improve handwriting performance by using specific handwriting programmes and similar standardised evaluation instruments. Practitioners of OT intervention should consider collaboration with teachers, parents and other health professionals to expedite effectiveness of intervention in handwriting performance components.

Hypertension is highly prevalent in Malaysia and even the rest of the world. Primary aldosteronism (PA) is one of the most common treatable cause of secondary hypertension. PA occurs due to excessive secretion of aldosterone in the adrenal glands. Up to one in five resistant hypertension cases are due to PA. Therefore, there are a high number of individuals who have the potential to be cured of their hypertension. However, this is difficult to achieve due to limitations in the procedure of diagnosing the PA disease. The challenge now is to know the best usage of available diagnostic methods to detect those who would most likely be cured of hypertension which may be associated with the genotype of the disease. In the past decade, five genes have been found to cause excess aldosterone production in aldosteroneproducing adenomas (APAs), namely KCNJ5, ATP1A1, ATP2B3, CACNA1D and CTNNB1. These somatic mutations have been found to activate the intracellular signaling pathway that regulates aldosterone production. Studies on bilateral adrenal hyperplasia (BAH) samples also have identified the genetic causes for the many hereditary hyperaldosteronism, namely familial hyperaldosteronism types I, II, III, and IV/V. Herein we review the genetic factors of PA as a result of either aldosterone-stimulating somatic mutations or germline variants, and the associated clinical phenotype.

The question of whether dyslexic children have visual cognitive differences in terms of brain activity as compared to normal children remains unsolved. Here, we aimed to study the neuronal source activity during visual attentional processing reflected in the P300 Event-Related Potential (ERP) component, when being exposed to the different congruency of visual images on dyslexic children by utilizing an ERP. Twelve dyslexic and twelve non-dyslexic children in the range of age 8 to 11 years old took part in this study. They pressed button ‘1’ when they saw a congruence image of the animal in its natural habitat and button ‘2’ for incongruence animal images in non-natural habitat. The source localization of P300 was executed on the grand average waveform by utilising Standardised Low-Resolution Brain Electromagnetic Tomography (sLORETA) algorithm provided by Net Station software. The BA 19 of the left occipital lobe was the most activated during congruence and incongruence images in the dyslexic children. As for the control children, BA 18 and BA 17 of the occipital lobe were activated during congruence and incongruence images, respectively. In sum, there were no differences in source activity areas during both visual images in dyslexic children as compared to the control children, which brings us to a conclusion that the visual attentional activity in dyslexic children used the brain areas that are associated with visual characteristics rather than context differences.

A post-mortem decomposition is defined by the evaluation of the physical and chemical changes of a cadaver or a carcass in order to estimate the cause of death and the time of death. The purpose of this study is not to replicate a real crime scene but to enhance knowledge of the effects of clothing in a decomposition process, mainly, the effects of layered cotton clothing on the post-mortem decomposition of adult female rat carcasses. Fifteen rats were divided into three groups: control, one-layered and two-layered clothed. The control subjects were unclothed and used to compare the post-mortem changes with the clothed subjects, one-layered and two-layered rat carcasses. All subjects were placed outdoor, 2.5 meters away from each other on grass bushes and dead leaves. Ambient temperature and humidity were recorded to observe if it associates with the post-mortem changes of the rats. Insect activity on each subject was observed. Post-mortem changes were measured using the Total Body Score system. The results showed that the control group underwent a faster decomposition compared to the clothed groups. The different layers of clothing did not show a vast difference in post-mortem changes. The ambient temperature of 28°C influences the post-mortem decomposition. The decomposition was rapid under the dominance of maggots compared to ants as ant colonies delayed the decomposition process. The study gave the knowledge of the effect of clothing in decomposition of female rats in forensic science.

Foodborne disease is among the primary illness that causes morbidity and mortality in the world. Several studies show that most students do not have adequate food safety knowledge to protect themselves against foodborne diseases. This study aimed to determine the food safety knowledge, behaviour, and beliefs among undergraduate students at a local university in Malaysia. This cross-sectional study involves 121 respondents from three health science-related faculties at the studied institution. The questionnaire was distributed via an online platform. This study used multiple-choiceformat questions for Food Safety Knowledge and a Likert type scale for Food Safety Behaviour and Belief question statements. Most of the respondents were female (78%). About 16% of the respondents have experience working / volunteering in food services, and half of them are involved in food handling during their services. This study recorded a moderate score in all sections (knowledge, behaviour, beliefs) with a total percentage score of 60.3%, 60.3%, and 66.1%, respectively. A strong but not significant correlation between food safety knowledge and beliefs (r = 0.69 p > 0.05) and between food safety knowledge and behaviour (r = 0.83 p > 0.05) were observed. This study is useful as a basis to develop a targeted food safety education program among undergraduate students. Students with high knowledge of food safety will increase food safety beliefs and behaviour, thus preventing them from getting any foodborne illness.

Several studies show that most students do not have adequate food safety knowledge to protect themselves against foodborne diseases. This study aimed to determine the food safety knowledge, behaviour, and beliefs among undergraduate students at a local university in Malaysia. This cross-sectional study involves 121 respondents from three health science-related faculties at the studied institution. The questionnaire was distributed via an online platform. This study used multiple-choiceformat questions for Food Safety Knowledge and a Likert type scale for Food Safety Behaviour and Belief question statements. Most of the respondents were female (78%). About 16% of the respondents have experience working / volunteering in food services, and half of them are involved in food handling during their services. This study recorded a moderate score in all sections (knowledge, behaviour, beliefs) with a total percentage score of 60.3%, 60.3%, and 66.1%, respectively. A strong but not significant correlation between food safety knowledge and beliefs (r = 0.69 p > 0.05) and between food safety knowledge and behaviour (r = 0.83 p > 0.05) were observed. This study is useful as a basis to develop a targeted food safety education program among undergraduate students. Students with high knowledge of food safety will increase food safety beliefs and behaviour, thus preventing them from getting any foodborne illness.","PeriodicalId":17686,"journal":{"name":"Jurnal Sains Kesihatan Malaysia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46982301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Projecting future infant mortality rate (IMR) is an important subject in ensuring the stability of health in one nation or a specific region in general. Secondary data of IMR from December 1950 until December 2020 from United NationsWorld Population Prospects were used to project the trend of IMR in Malaysia up to 2023. In this study, five different forecasting models were adopted including Mean model, Naïve model, Autoregressive Integrated Moving Average (ARIMA) model, Exponential State Space model and Neural Network model. The results were analyzed using R programing and RStudio. The out-sample forecasts of mortality rates were evaluated using six error measures namely, Mean Error (ME), Root Mean Square Error (RMSE), Mean Absolute Error (MAE), Mean Percentage Error (MPE), Mean Absolute Percentage Error (MAPE) and Mean Absolute Scaled Error (MASE). Consequently, the keen analysis was focused on the trend and projection of infant mortality rate in the future using the most accurate model. The results showed that the “win” model for this study is ARIMA (0,2,0) model. The model provided a consistent estimate of IMR in relation to a similar decreasing pattern as shown by the original data and hence a reliable projection of IMR. The three ahead forecast values showed that IMR is likely to keep on continuously decreasing in the future. This study could become a guideline for human resource management and health care allocation planning. A forecast of IMR can help the implementation of interventions to reduce the burden of infant mortality within the target range.
