Objective: To characterise a collection of pili-carrying and none pili-carrying pneumococcal isolates of clinical origin for serotypes, antibiotic resistance and genotype. Methods: In total, 42 clinical isolates were collected between October 2017 and December 2019. Those isolates were analysed for antimicrobial susceptibility, serotype distribution, detection of pneumococcal virulence and pilus genes. Multilocus sequence typing was performed only for piliated isolates, followed by phylogenetic analysis. Results: The common isolation sites among the pneumococcal isolates were tracheal aspirate (28.6%), blood (26.2%), and sputum (23.8%). Fifty percent isolates were resistant to erythromycin, tetracycline (50.0%) and trimethoprim-sulfamethoxazole (43.0%). The most frequent were serotypes 19F (28.6%), 6A/B (23.8%) and 19A (14.3%). Piliated isolates were detected in a small proportion (33.3%); 64.3% were multidrug-resistant. ST320 was the prevalent sequence type among the piliated isolates and genetically related to the Pneumococcal Molecular Epidemiology Network clones Taiwan 19F -14 (CC271). In the phylogenetic analysis, some piliated isolates showed a close association having similar ST320, carrying serotype 19A and both pilus genes indicating their clonal spread. Conclusions: Pneumococcal lineages of piliated isolates have been globally disseminated and pili could have played a role in the spread of antibiotic resistant clones.

Background: The spread of COVID-19 was inevitable and has not spared small and isolated communities, including the community of Perhentian Island in Besut District, Terengganu. Managing clusters in small islands can be difficult, given the limited resources. This study explores the characteristics of COVID-19 cases and the experience of outbreak containment at Perhentian Island. Methodology: A retrospective study involving record review of COVID-19 cases and at-risk individuals registered under Perhentian Cluster were retrieved from the Besut District Health Office COVID-19 online registry from the 16thAugust2021 until 6thOctober 2021. All notified cases and close contacts who fulfilled the inclusion criteria were extracted and analysed using descriptive statistics. Results: A total of 1,093 community members of Perhentian Island were screened of which 170 (15.5%) tested positive for COVID-19, while 923 (84.5%) tested negative. Among individuals who tested positive, the majority were adults (52.4%), male (51.8%), Malays (98.8%), and villagers (96.5%). Clinical characteristics were categorized into: asymptomatic (55.9%), had no known medical comorbidities (90.6%), low-risk groups (87.1%), vaccinated (57.6%), and admitted to PKRC (97.1%) for treatment. Multiple agencies were involved in the outbreak containment of the Perhentian Cluster, working collectively and in good coordination. Conclusion The outbreak was attributed to community gatherings and close interactions among villagers. Prompt actions, targeted planning, and inter-agency collaboration were the key factors in successful containment of further spread of COVID-19 in Perhentian Island.

Introduction: Prevalence of malnourished children in Putrajaya was unexpectedly high in 2016. This paper describes the study protocol for a case-control study conducted to identify the associated factors of malnutrition among children under 5 years old in Putrajaya. Methods: This study involved two phases. Phase I was ‘screening’ where all children aged 6-59 months in 118 preschools and four government health clinics were measured for their weight and height. The World Health Organization Anthro software was used to determine the nutritional status of these children. Phase II was the ‘interview’ where children from screening were sampled into four pairs of case and control. The optimum sample size for the case of stunted, wasted, underweight, and overweight were 380, 335, 318, and 308, respectively. The same number of controls were recruited. Parents/caregivers of selected children were approached to obtain data on parental factors, children factors, food intake factors, and environmental factors that contributed to malnutrition. Data analysis was performed by multiple logistic regression in SPSS version 26. Results: Screening phase successfully measured 8,261 (50.1%) children from an estimated 16,500 children under 5 years old in Putrajaya. The number of children who were stunted, wasted, underweight, and overweight were 2,105 (25.5%), 512 (6.2%), 1,516 (18.4%), and 248 (3.0%), respectively. As overweight was undersampled, the number of controls for overweight was doubled to increase the power of the study. Parents/caregivers of selected cases and controls were interviewed in their household or any other venues at their convenience. Conclusion: This protocol promises beneficial outputs to stakeholders and policy makers that can be used for combating malnutrition in children.

Excessive salt intake has been linked to the development of hypertension and non-communicable diseases. This study aims to explore the different types of salt reduction intervention implemented among adults aged ≥18 years and to identify the suitable settings, duration and tools used for effective salt reduction interventions. This review adapted the established structured scoping review framework by Arksey and O’Malley. Related articles from the year 2008 to 2018 were retrieved based on the study objectives using keywords in electronic databases and through a bibliographic search of books, reports, conference proceedings, posters and summaries. Out of 130 potentially relevant full-text articles assessed, 14 articles were included in the review. Suitable salt reduction initiatives for the community who regularly consume home-cooked food are through cooking and usage of a tool such as a salt-restriction spoon, together with awareness on the benefits of salt reduction in their daily diet. Healthy catering initiative should be implemented in the workplace or institution-based settings. Policy development targeting the source of salts such as mandatory usage of salt-substitutes or Front-of-Pack labelling of salt content in all food products suitable for population-level intervention.

Introduction: Adequate, nutritive and safe foods are crucial for growth and healthy living. Adolescents are vulnerable to food insecurity. This study was aimed at determining the demographic factors, food security status, health-related quality of life (HRQOL) and body weight status of adolescents in Mentakab, Pahang, Malaysia. Methods: This study involved 160 households that comprised pairs of mothers and children aged 13-17 years. Face-to-face interviews were conducted with the mothers to assess their demographic and food security status (Radimer/Cornell Hunger and Food Insecurity Instrument). Meanwhile, the children answered a self-administered HRQOL questionnaire (Pediatric Quality of Life Inventory, PedsQL). Body weight and height were measured to obtain the body mass index (BMI). Results: About 48.8% of the adolescents were from households with food insecurity. The number of school-going siblings, occupation status of mother, occupation status of father, household income and house ownership status were predictors of food security status (p<0.05). After controlling for covariates, the HRQOL score and BMI were higher in adolescents from food-secure households than adolescents from food- insecure households (p<0.01). Conclusion: The prevalence of food insecurity was high and multifactorial. Food insecurity was further associated with HRQOL and BMI. Food assistance programmes are recommended to directly alleviate food insecurity. Concurrently, monetary and educational aids are advocated to reduce the economic burden, especially in low-income households.

BACKGROUND: Urinary tract is subjected to a variety of disorders such as urethral stricture, which often develops as a result of scarring process. Urethral stricture can be treated by urethral dilation and urethrotomy; but in cases of long urethral strictures, substitution urethroplasty with genital skin and buccal mucosa grafts is the only option. However a number of complications such as infection as a result of hair growth in neo-urethra, and stone formation restrict the application of those grafts. Therefore, tissue engineering techniques recently emerged as an alternative approach, aiming to overcome those restrictions. The aim of this review is to provide a comprehensive coverage on the strategies employed and the translational status of urethral tissue engineering over the past years and to propose a combinatory strategy for the future of urethral tissue engineering. METHODS: Data collection was based on the key articles published in English language in years between 2006 and 2018 using the searching terms of urethral stricture and tissue engineering on PubMed database. RESULTS: Differentiation of mesenchymal stem cells into urothelial and smooth muscle cells to be used for urologic application does not offer any advantage over autologous urothelial and smooth muscle cells. Among studied scaffolds, synthetic scaffolds with proper porosity and mechanical strength is the best option to be used for urethral tissue engineering. CONCLUSION: Hypoxia-preconditioned mesenchymal stem cells in combination with autologous cells seeded on a prevascularized synthetic and biodegradable scaffold can be said to be the best combinatory strategy in engineering of human urethra.

Neurophobia, defined as ‘the fear of neural sciences and neurology’ is reported among medical students, which threatenedtheir performance in neurology course. This phenomenon has not been studied among rehabilitation sciences studentsdespite the significance of neurology as an area for rehabilitation. In this study we aim to assess the perceptions of neurologycourse and the possibility of neurophobia existence among rehabilitation sciences students of Universiti KebangsaanMalaysia (UKM). We also aimed to identify learning methods which are regarded as useful among the students. A surveyusing self-administered questionnaires was conducted among 73 students from School of Rehabilitation Sciences of theuniversity. Questions in the questionnaire were adapted from previous studies, in which neurophobia was indicated by poorknowledge and low confidence level in managing neurology course. Results showed that the percentage of participantswho perceived having good knowledge of neurology was significantly higher than the percentage who claimed of havingpoor knowledge level (90.4% versus 9.6%, p < 0.01). Similarly, the percentage of participants who claimed having highconfidence to handle neurology cases was higher than the percentage who expressed lack of confidence (79.2% versus20.8%, p = 0.03). However, neurology course was perceived as difficult by majority of the participants (78.1%) whencompared to other courses. Majority of the participants (97.3%) perceived clinical teaching as a useful method of learningrehabilitation science courses including neurology followed by problem-based learning (90.4%). While limited exposureto neurology cases was claimed as the main reason to why neurology is difficult. In conclusion, although neurology isperceived as a difficult course among rehabilitation sciences students, the students did not report lack of knowledge andconfidence in the course. This implies that neurophobia does not exist among UKM rehabilitation students. Enhancementof learning methods may assist in reducing the level of difficulty of neurology course among the students.

Introduction: Childhood obesity becomes a global epidemic with the majority are living in developing countries. Obese children are at risk of becoming obese adults with non-communicable diseases, which may further lead to huge economic burden for the affected countries. The study objectives were to determine the biosocial background contributing overweight and obesity among preschoolers in Putrajaya (2017) - sociodemographic, pre-and perinatal factors, feeding and weaning practices. Methods: Cross-sectional study was performed using cluster random sampling among 897 preschoolers, whose anthropometric body weights and heights were measured. The calculated BMI was used to determine their obese status based on WHO Growth Standards 2006 and Reference 2007. Their mothers were distributed with self-administered, validated, and pre-tested questionnaires regarding their children’s first two-years-of-life experience. Chi Square test was used for bivariate categorical analysis, Independent T-test and Mann Whitney U test for continuous data analysis. Multivariate binary logistic regression was executed to determine predictors of child obesity. Results: The prevalence of obese children was 7.4%, which can be predicted by the increase in child’s age (Adjusted Odd Ratio: 2.619; 95%CI: 1.435 – 4.780), mothers with higher level of education (AOR: 3.896; 95%CI: 1.127 – 13.470), and higher maternal BMI (AOR: 1.132; 95%CI: 1.057 – 1.213). Conclusion: Three predictors of child obesity can be derived from sociodemographic and pre-and perinatal factors. Further application on these predictors in more targeted interventions and policies need to be considered to reduce the prevalence of obesity and related non-communicable diseases in the country.

Objective: The primary objective of this study was to describe the neuroimaging changes of tuberculous meningitis (TBM), and to determine the role of neuroimaging in the diagnosis of TBM. Methods: Between January 2009 and July 2015, we prospectively recruited TBM patients in two hospitals in Malaysia. Neuroimaging was performed and findings were recorded. The control consists of other types of meningo-encephalitis seen over the same period. Results: Fifty four TBM patients were recruited. Leptomeningeal enhancement was seen in 39 (72.2%) patients, commonly at prepontine cistern and interpeduncular fossa. Hydrocephalus was observed in 38 (70.4%) patients, 25 (46.3%) patients had moderate and severe hydrocephalus. Thirty four patients (63.0%) had cerebral infarction. Tuberculoma were seen in 29 (53.7%) patients; 27 (50.0%) patients had classical tuberculoma, 2 (3.7%) patients had “other” type of tuberculoma, 18 (33.3%) patients had ≥5 tuberculoma, and 11 (20.4%) patients had < 5 tuberculoma. Fifteen (37.2%) patients had vasculitis, 6 (11.1%) patients had vasospasm. Close to nine tenth (88.9%) of the patients had ≥1 classical neuroimaging features, 77.8% had ≥ 2 classical imaging features of TBM (basal enhancement, hydrocephalus, basal ganglia / thalamic infarct, classical tuberculoma, and vasculitis/vasospasm). Only 4% with other types of meningitis/encephalitis had ≥1 feature, and 1% had two or more classical TBM neuroimaging features. The sensitivity of the imaging features of the imaging features for diagnosis of TBM was 88.9% and the specificity was 95.6%. Conclusion: The classic imaging features of basal enhancement, hydrocephalus, basal ganglia/thalamic infarct, classic tuberculoma, and vasculitis are sensitive and specific to diagnosis of TBM.

Limited studies on prevalence and risk factors of Premature Coronary Artery Disease (PCAD) were done in Malaysia, primarily on lipid profile. This cross sectional study aims to identify any changing patterns in prevalence and risk factors of Premature CAD between 2000 and 2012. From 2000 to 2012 we included 21862 patients who underwent the first Percutaneous Coronary Intervention (PCI). Analysis of risk factors was done to 1660 and 2098 patients from year 2007 and 2012 respectively. Age of less than 45 years was taken as PCAD. Data was collected from PCI database of National Heart Institute (NHI), NHI TrakCare System, and patients’ medical records. PCAD significantly decreased from 18.8% (2000) to 11.6% (2012). Malay ethnicity showed increasing trend over the years from 55.1% to 66.9%. Multiple logistic regression analysis in 2007 showed that smoking had the higher risk (AOR=2.52), followed by male gender (AOR=2.06), family history of PCAD (AOR=1.96), Indian ethnicity, (AOR=1.65), triglycerides level (AOR=1.20) and BMI (AOR=1.06). In 2012, family history of PCAD had the highest risk (AOR=2.00) followed by smoking (AOR=1.91) and BMI (AOR=1.11). There are changes in risk factors patterns of premature CAD between 2007 and 2012. Most of them are preventable at earlier stage.
