Introduction: Drug abuse is a prevalent issue in Malaysia, and a constant struggle to eradicate even among substance abusers who have received prior rehabilitation. Drug abuse has also been known to affect the quality of life of an individual, due to the stigma it carries. This research emphasized on studying the life quality of relapsed and first-time substance abusers in rehabilitation centres including their tendency towards aggression. Methods: A cross-sectional study was conducted to evaluate the current inpatients in Cure & Care Rehabilitation Centres (CCRC) in Peninsular Malaysia. Primary data was acquired using a self-administered questionnaire consisting of socio-demographic (Part A), quality of life (Part B) and aggression related questions (Part C). 417 individuals were selected through purposive sampling from five different centres. A statistical analysis was conducted using independent t-test, single linear regression and Kruskal-Wallis using SPSS version 25.0. Results: An analysis of the data presented no significant association between quality of life and tendency of aggression among relapsed and first time substance abusers (p>0.05). Based on the analysis and the outcome, age influences the level of aggression (p=0.018) while quality of life is affected by education level (p=0.017). Marital status is a factor that affects both the level of aggression (p=0.015) and quality of life (p=0.043). Conclusion: The findings may contribute to law enforcements in reducing violent crimes committed by drug abusers and rehabilitation efforts by rehabilitation centres, by establishing demographic profiles in relation to quality of life and aggression.

Introduction: Identification of remains recovered at advanced stages of decomposition can be problematic due to the lack of physical evidence. Nonetheless, human dentition is least susceptible to decomposition and as such carry a significant value in personal identification of decomposed remains. Demirjian’s method of age estimation was developed specifically for children with developing dentition. In this article, a method on adapting the Demirjian’s method for Malay ethnic-specific age estimation using the third molar development is presented. Methods: Orthopantomograms of Malay subjects aged 18 to 25 were obtained from UiTM Sungai Buloh. Total of 318 samples were taken, comprising of 123 and 195 images from male and female subjects. Development of right and left mandibular third molar was classified according to the eight stages of development as illustrated in Demirjian’s method. Data obtained were subjected to statistical analysis such as descriptive statistics and analysis of variance. The intra- and inter-gender variation between left and right mandibular third molar was evaluated using independent student t-test and analysis of variance, respectively. Results: Intra-gender comparison analysis revealed a significant difference in the female and male with a p-value of 0.000 and 0.003, respectively. Regression equation to estimate age based on third molar development were formulated according to dental age and maturity score. Conclusion: The Demirjian’s method was successfully adapted for age estimation of individuals of Malay ethnicity. These findings can help with victim identification in cases of poor skeletal framework recovery and highly decomposed remains.

Introduction: A cross-sectional study was conducted to provide preliminary insight of Awareness, Knowledge and Attitude (AKA) assessment on urinary tract infection (UTI) among adolescents which includes the general level of AKA and correlation between the domains as well as the relationship between Total AKA and the sociodemographic factors. Methods: A modified and adapted questionnaire was developed, consisting of socio-demographic questions and AKA domains employing descriptive statistics, linear regression and multiple regression analysis via SPSS Version 23.0. Results: In general, AKA level was reported as moderate (0.5 ± 0.11). Among the three domains, Knowledge (0.70 ± 0.12) risen with the most astounding mean, took after Awareness (0.36 ± 0.22) and Attitude (0.65 ± 0.11). A positive but weak correlation was found between the domains; Awareness and Knowledge is significant at p = 0.034, r = 0.157; R2 = 0.02 and similarly, a weak correlation was also found between Knowledge and Attitude which is significant at p = 0.000, r = 0.411; R2 = 0.17. After covariates adjustment, female gender was found to have the strongest relationship with Total AKA. Conclusion: The general level of Total AKA on UTI is moderate. The AKA domains in this study was found to be positively correlated and female was found to be the best predictor for a better Total AKA on UTI. Thus, these findings provide important information to formulate an effective education intervention to improve the AKA on UTI among adolescents.

INTRODUCTION: We investigated the knowledge, attitudes and practice (KAP) towards coronavirus disease 2019 (COVID-19) and its related preventive measures in Singaporeans aged ≥60 years. METHODS: This was a population-based, cross-sectional, mixed-methods study (13 May 2020-9 June 2020) of participants aged ≥ 60 years. Self-reported KAP about ten symptoms and six government-endorsed preventive measures related to COVID-19 were evaluated. Multivariable regression models were used to identify sociodemographic and health-related factors associated with KAP in our sample. Associations between knowledge/attitude scores and practice categories were determined using logistic regression. Seventy-eight participants were interviewed qualitatively about the practice of additional preventive measures and data were analysed thematically. RESULTS: Mean awareness score of COVID-19 symptoms was 7.2/10. The most known symptom was fever (93.0%) and the least known was diarrhoea (33.5%). Most participants knew all six preventive measures (90.4%), perceived them as effective (78.7%) and practised 'wear a mask' (97.2%). Indians, Malays and participants living in smaller housing had poorer mean scores for knowledge of COVID-19 symptoms. Older participants had poorer attitudes towards preventive measures. Compared to Chinese, Indians had lower odds of practising three out of six recommendations. A one-point increase in score for knowledge and attitudes regarding preventive measures resulted in higher odds of always practising three of six and two of six measures, respectively. Qualitative interviews revealed use of other preventive measures, for example, maintaining a healthy lifestyle. CONCLUSIONS Elderly Singaporeans displayed high levels of KAP about COVID-19 and its related preventive measures, with a positive association between levels of knowledge/attitude and practice. However, important ethnic and socioeconomic disparities were evident, indicating that key vulnerabilities remain, which require immediate attention.
