Introduction: Dental anxiety is a common problem faced by dental practitioners worldwide. Generally, the management of dental anxiety can be classified as pharmacological and non-pharmacological approaches, in multiple studies and reports available on this subject.Aims and objectives: This paper will provide a general overview of the pharmacological and nonpharmacological strategies in the management of dental anxiety, supported by dental literature. This would help dental practitioners understand the benefits and limitations of the different methods of treating their anxious patients.Methodology: This is a narrative review and a summary of the different approaches and methods available in the management of dental anxiety. Relevant articles were searched from the online databases of PubMed, ScienceDirect, and Google Scholar, and the keywords used to identify the papers were ‘Dental Anxiety’, ‘Pharmacological’, and ‘Non-pharmacological’.Conclusion: Appropriate management of dental anxiety is crucial to ensure a successful dental procedure. The choice of the anxiety management must be based on the complete understanding of the particular patient, identifying the source of anxiety, and working hand-in-hand with the patient for better oral health care.

The undergraduate dental degree in Malaysia is regulated by the Malaysian Dental Council (MDC) (Standard of Undergraduate Competencies), Code of Professional Conduct of the Malaysian Dental Council, the Malaysian Qualification Framework 2.0 and the Malaysian Quality Agency (MQA) quality assurance documents. These primary documents emphasize the importance of professional ethics and law in dentistry as will be further detailed and discussed later. This study reflects on the need to integrate ethics, professionalism and law with sufficient coverage in terms of content and emphasis in the dental undergraduate curriculum. Literature and benchmarking practices are reviewed for a deeper reflection of the current needs in a professional dental ethics and law education course. The present study is primarily focused on regulatory requirements, legal cases and comparative literature to serve as a reference on how professional ethics and law courses may be conducted. As an incidental measure, a reflection as to how the course of study of professional ethics is delivered in a local university is considered in a selected local university’s undergraduate dental curriculum. The findings indicate that ethics professionalism and dental law is not given sufficient emphasis as it is included as one of the minor components within another overcrowded subject and the coverage of what is taught is limited in context. This paper is an invitation to all dental schools to review and reflect whether, given the emphasis on professional ethics, legal and regulatory compliance in the regulatory documents, it is adequately reflected in their dental curriculum. In this regard, some benchmarking references are done to suggest what such a course should cover, for consideration of the dental schools.

The COVID-19 pandemic resulted in 5 consecutive Movement Control Orders (MCOs) in Malaysia in an attempt to flatten the epidemiological curve, with a reduction of cases. This study aims to use statistical analysis to assess whether the decisive public health interventions in the MCO were efficacious. Three statistical tests were employed: Mann-Kendall trend analysis; one way between groups ANOVA; and Pearson correlation test. Results demonstrated significant differences between the second block, MCO 3-5, compared to MCO 1-2. Johor and Selangor states experienced significant increase in early MCO, whereas Sarawak and Selangor states experienced significant decrease by MCO 3-5. The northern border states of Kedah, Perlis and Kelantan, had caseloads stabilised to zero by MCO 4/MCO 5. This study demonstrates that the MCO was effective within the target of twice the two-week incubation period of COVID-19, with cases from community transmission and importation through the air and southern land borders. Selangor and Sarawak had higher cases in early MCO due to situational factors. In conclusion, MCO has been efficacious, with different states attaining different levels of case reduction due to individualised reasons.

Background: This research aimed to examine the association between resilience and lifestyle in line with H.M. King Bhumibol Aduyadej’s sufficiency economy philosophy (SEP) among university students studying in restive insurgent areas of Southern Thailand. Methods: Data were collected on a single occasion between 8 August 2018 and 8 October 2018, at Prince of Songkla University, Pattani campus, located in the restive areas of Southern Thailand. A total of 443 university students were assessed using the 20-item Thai Resilience Quotient screening test, and 35-item questionnaire for lifestyle following H.M. King Bhumibol Aduyadej’s SEP. Data were analyzed by using R software package for descriptive analysis, Chi-square and logistic regression. Results: Of the 443 university students who participated in the survey, most participants were Thai, female and Muslim (94.1%, 80.3% and 75.5%, respectively). Most of them perceived that they lived sufficiently, following H.M. King Bhumibol Aduyadej’s SEP, together with normal or higher than normal level of resilience (67.9% and 64.8%, respectively). The association between resillience in total to perception of lifestyle, in line with H.M. King Bhumibol Aduyadej’s SEP , was statistically significant. Resilience was categorized by domains of emotional stability, willpower and coping skill (all p-values<0.001). Sufficient living according to the late king’s SEP was found to be 3.42 times higher than in students who lived non sufficiently (95%CI=2.24, 5.22). Conclusion: Resilience and self-perceived lifestyle according to H.M. King Bhumibol Aduyadej’s SEP were found to have a statistically significant association among university students who studied in restive insurgent areas of South Thailand.
背景:本研究旨在考察泰国南部动乱地区大学生的心理弹性与生活方式之间的关系，这些大学生符合普密蓬·阿杜德国王的充足经济哲学(SEP)。方法:数据于2018年8月8日至2018年10月8日在位于泰国南部动荡地区的宋卡王子大学Pattani校区一次性收集。采用20项泰式弹性商筛选测验和35项普密蓬国王SEP生活方式问卷对443名大学生进行评估，数据采用R软件包进行描述性分析、卡方分析和logistic回归。结果:443名参与调查的大学生中，泰国人、女性和穆斯林占比最高(分别为94.1%、80.3%和75.5%)。他们中的大多数人认为他们的生活足够，遵循国王普密蓬·阿杜德(H.M. King Bhumibol Aduyadej)的SEP，以及正常或高于正常水平的弹性(分别为67.9%和64.8%)。总体复原力与生活方式感知之间的关联，与普密蓬·阿杜德国王的SEP一致，具有统计学意义。弹性以情绪稳定性、意志力和应对技能为分类域(p值均<0.001)。根据已故国王的SEP，生活充足的学生比生活不充足的学生高3.42倍(95%CI=2.24, 5.22)。结论:在泰国南部动乱地区学习的大学生中，泰国国王普密蓬·阿杜德的心理弹性和自我感知的生活方式具有显著的统计学意义。

Studies have found the association between hypercholesterolemia with oxidative stress and atherogenesis. Atherosclerosis has become one of the leading causes of mortality among industrial countries due to abnormal cholesterol metabolism, inflammation of arterial wall and build-up of atherosclerotic plaque. This disease has been recently linked with alpha lipoic acid (ALA), a mitochondrial compound with antioxidative effects in water- and fat-soluble mediums, in both oxidized and reduced forms: lipoic acid (LA) and dihydrolipoic acid (DHLA), respectively. This article provides a comprehensive review of the development and progression of atherosclerosis and the roles and regulations of ALA as a potent antioxidant against atherosclerosis.

According to tradition, plants and herbs are potential cures for numerous illnesses. In recent decades, they have gained worldwide recognition as critical sources of new drugs, especially for cancer, and the focus on medicinal plant research has increased tremendously. Currently, research scientists attribute the occurrence of post-chemotherapy tumour exacerbation to the presence of cancer stem cells hidden in the bulk of the malignant tumour, forming a rare subpopulation that plays a major role in tumour re-initiation, progression and recurrence. There is increasing evidence of cancer stem cells in a wide array of tumours, and these cells could be the crucial target for future chemotherapy approaches. This review of the major plant-based phytochemicals with documented antagonistic activities against cancer stem cells, their molecular targets and the mechanisms involved, may serve as a guide for developing from the existing natural agents, more effective, and broader spectrum anti-cancer stem cell compounds with the potential for clinical application.

Congenital heart disease (CHD) is the result of a complicated interplay between genetic and non-genetic, or “environmental,” factors acting on the foetus and one of those environmental factors is maternal hyperglycemia. Maternal diabetes has teratogenic effects on the evolution of the foetal cardiovascular system; as a consequence, cardiovascular malformations are the most common anomalies in infants of diabetic mothers with transposition of the great arteries, tricuspid atresia and truncus arteriosus being some of the common cardiac malformations encountered. Thus, it is important to perform a detailed heart examination at autopsy of perinatal deaths in order to ascertain related anomalies. We present a case of stillbirth in a woman with Type 1 Diabetes mellitus on insulin therapy who claims she was unaware about her pregnancy.

The Takotsubo syndrome is an acquired, non-ischemic stress-induced cardiomyopathy popularly known as the ‘broken heart syndrome’. It is an acute left ventricular dysfunction presenting mostly in older women after an intensely stressful event. The exact pathophysiology remains elusive. The term came into existence in the early 1990s in Japan, where the distinctive change in the shape of the left ventricle with apical ballooning during systole, resembled the Takotsubo, an octopus pot used bythe Japanese fisherman. From a rare underrecognized syndrome, it has been increasingly recognised as a form of acute cardiac failure. Clinical diagnosis of the syndrome may be unidentified due to its similarity with the acute coronary syndrome, but without the narrowing of coronary vessels in angiographic imaging. There is a substantial elevation of the cardiac biomarkers, troponin and the natriuretic peptides which helps in differentiating the Takotsubo syndrome from myocardial infarction. A case report of a 59-year old Malaysian lady with typical, recurrent episodes of the Takotsubo syndrome is presented.

Background: Strength of leg musculature is crucial to generate propulsive force during rowing. The purpose of this study was to determine the relationship of isokinetic dominant leg strength and 2 km time trial on stationary rowing ergometer among male national rowers. Methods: Seventeen male national rowers were recruited for the study. Their hip and knee isokinetic strength were determined in the sagittal plane at 60°/s angular velocity. The relationship between the hip and knee strength, and 2 km time trial performance were evaluated using Pearson correlation. Results: The national rowers completed the 2 km time trial duration in 7.20±0.39 minutes. The hamstring to quadriceps ratio (H:Q) was significantly correlated to 2 km time trial performance (r=-0.491, p=0.045). No other significant relationships between hip and knee isokinetic strength and 2 km time trial performance were observed. Conclusion: Increased isokinetic knee strength ratio (H:Q) may enhance 2 km time trial performance among male national rowers. Other isokinetic variables of hip and knee isokinetic strength were not significantly related to 2 km time trial.

Objective: This study aimed to assess self-perceived aesthetics and orthodontic need, information-seeking behaviours and knowledge on orthodontic treatment among young adults in Malaysia. Methods: A cross-sectional study was conducted among 933 polytechnic students in Malaysia using a selfadministered questionnaire. The Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN) was used to assess self-perceived orthodontic need. Respondents were also asked about their intention to seek orthodontic treatment. Those showing intention were further asked about their reason(s) for seeking treatment, their information-seeking behaviours, and knowledge on orthodontic treatment. Data was analysed using SPSS. Results: The overall response rate was 93.2% with the mean age of 20.43 (SD±1.07). Although most of the respondents rated themselves under the no treatment need category of the AC-IOTN scale, 61.9% reported intention to seek orthodontic treatment. The main reason for seeking treatment was to improve dental function (45.3%) and aesthetics (40.1%). Most claimed to look for information prior to orthodontic treatment, either using online or offline platforms. Many relied on friends (83.3%) as a source of information and more than half used online sources including social media and websites. A minority demonstrated lack of knowledge in terms of appropriate places to receive treatment (2.2%) and qualification of orthodontic practitioners (37.7%). Conclusions: The majority of young Malaysian adults have high intention to seek orthodontic treatment regardless of their perceived need. A minority had lack of knowledge about qualified orthodontic providers and places to receive treatment. Majority reported positive attitudes towards information-seeking behaviour prior to seeking orthodontic treatment.
