Introduction:
Insulin therapy is essential in the management of type 2 diabetes mellitus (T2DM), but is often associated with treatment
burden, hypoglycemia, and potential overtreatment. Insulin deintensification is increasingly recommended for
appropriately selected patients; however, there is limited real-world evidence to guide patient selection and to identify
modifiable factors that influence successful insulin deintensification. This study aimed to identify clinical predictors,
including modifiable factors, associated with successful insulin deintensification in a primary care setting.
Methodology:
A multicentre retrospective observational study was conducted across seven government primary care clinics in the Petaling
District. Adult patients with T2DM undergoing insulin deintensification were included. Successful insulin deintensification
was defined as maintenance or improvement of hemoglobin A1c following insulin discontinuation, dose reduction, or
reduction in injection frequency. Paired outcomes were analyzed using the Wilcoxon signed-rank test. Between-group
comparisons were performed using the Mann–Whitney U test and Chi-square or Fisher’s exact test. Multivariable logistic
regression was used to identify independent predictors of successful insulin deintensification.
Results:
A total of 261 patients were included. Glycemic control remained stable following insulin deintensification (p = 0.334).
Significant reductions in body weight (−0.41 kg, p = 0.012) and total daily insulin dose (23.1% reduction, p <0.001) were
observed. Univariate analysis did not demonstrate significant differences between groups. However, multivariable logistic
regression identified SGLT-2 inhibitor use (aOR 3.23, 95% CI 1.28–8.18, p = 0.013) and regular SMBG (aOR 2.00, 95% CI
1.05–3.81, p = 0.035) as independent predictors of successful insulin deintensification.
Conclusion
Insulin deintensification can be successfully implemented without compromising glycemic control. Identified predictors,
including modifiable factors such as SGLT-2 inhibitor use and SMBG, provide clinically actionable insights to guide patient
selection and treatment optimization. These findings challenge the traditional reluctance toward insulin deintensification
and support a more evidence-based and individualized approach in routine clinical practice.

INTRODUCTION:
Multisystem inflammatory syndrome in children (MIS-C) is a rare inflammatory syndrome with multisystem involvement affecting children exposed to COVID-19. This condition is rarely reported in East Asia and was not detected in Singapore until 2021. We present 12 cases of MIS-C diagnosed in KK Women's and Children's Hospital (KKH) from October 2021 to December 2021.
METHOD:
We conducted an observational study on cases fulfilling the Singapore Ministry of Health criteria for MIS-C from January 2020 to December 2021 in KKH. Medical records were reviewed to obtain information on clinical presentation, disease course, treatment received and outcomes.
RESULTS:
In the 12 cases detected, the median age was 7.50 years (interquartile range 4.00-9.25); 8 were male. All patients had mucocutaneous symptoms similar to Kawasaki disease. Other commonly involved systems were: haematological (coagulopathy 100%, lymphopaenia 91.70% and thrombocytopaenia 75.00%), gastrointestinal (75.00%) and cardiovascular (83.30%). Six patients (50.00%) had shock and were admitted to the intensive care unit. The majority of patients received treatment within 2 days of hospitalisation with intravenous immunoglobulin (IVIg) and steroids. All survived; the majority had normal echocardiograms and no long-term organ sequelae at 6 months post-discharge.
CONCLUSION
MIS-C emerged in Singapore as the incidence of COVID-19 in the community increased in 2021. The clinical presentation of our patients is similar to earlier reports, with some significant differences from Kawasaki disease. Multidisciplinary management, timely diagnosis, and early initiation of treatment with IVIg and steroids likely contributed to comparatively good outcomes. Our cases highlight the need for continued awareness of MIS-C among physicians, and surveillance of its incidence, short- and long-term outcomes.

Introduction: The emergence of a novel Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted
in a pandemic. Rapid and accurate diagnosis method is crucial to reduce the disease burden and to improve early
diagnosis approaches to control of the disease. Real time Reverse transcriptase PCR (qRT-PCR) has been identified by
the World Health Organization as the most sensitive and specific method of detection. However, the success of this
assay relies on the quantity and quality of the extracted viral RNA. Methods: Various methods have been developed
for nucleic acid extraction however, the methods have not been assessed. RNA extraction was performed from 24
nasopharyngeal swab samples using a manual extraction kit (GF-1) and an automated extraction kit (Genolution).
The concentration and purity of the extracted RNA samples were measured, and its performance were tested using
qRT-PCR. Results: The average concentration and purity of the RNA samples extracted using GF-1 kit was higher
compared to Genolution. Similarly, the qRT-PCR assay using the RNA samples extracted using manual extraction
was better compared to automated kit. Conclusion: Both the manual and automated extraction kits have its advantages and disadvantages in terms of yield and purity. However, with proper optimization, both methods may be used
for routine molecular diagnostic of COVID-19 in laboratories.

Introduction: Limited studies have been documented on the presence of pathogenic Leptospira in public markets
serving the community in sub-districts of Selangor. The aim of this study was to detect the presence of pathogenic
Leptospira in rats using a gene encoding an outer membrane lipoprotein LipL32. Methods: Polymerase chain reaction (PCR) was performed using LipL32 primers on sixty kidney samples of rats trapped at two locations of study;
Pasar Borong Selangor in Seri Kembangan and Pasar Basah Bandar Baru Bangi in Bangi. Results: Out of 60 samples
analysed, 36.7% were positive for the presence of LipL32. All positive samples highly matched (>94%) nucleotide
sequence for LipL32 of pathogenic Leptospira and related to the pathogens through phylogenetic analysis. Conclusion: The detection of LipL32 indicates the potential presence of pathogenic Leptospira species at public markets.
Although only 60 rats were successfully trapped, the rats are mobile and might further transmit the pathogenic organisms to other areas.

Introduction:
Multitude studies have shown perception is an integral factor associated with smoking, However, no such tool was available in Malay language. In this study, we established a Bahasa Malaysia version of PTSQ (BM-PTSQ) and tested the validity and reliability among secondary school adolescents.
Methods:
The English version of PTSQ originally consists of 12 items. It was translated into Bahasa Malaysia and back-translated again into English to check for consistency. After face validity (face-to-face query) was determined among 20 secondary school adolescents, only 10 items were included in the survey. Construct validity was established from 407 school adolescents through random selection in the same locality. More than 60% of the respondents were female, a majority (67.3%) were schooling in rural areas. Then, the reliability of the questionnaire was determined with Cronbach's alpha.
Results:
EFA has grouped PTSQ into two components, they are associated with either knowledge or attitude towards smoking. The variance and Cronbach's alpha for the first and second component were 38.24% and 0.861 (7 items) and 21.62% and 0.661 (3 items) respectively.
Conclusion
The PTSQ showed good validity and reliability for measurement of perception in smoking among school adolescents in Malaysia, thus this is a viable measurement tool. More importantly this study shows an urgent need to improve the smoking education among adolescents in Malaysia.

Introduction: Eating out has always been associated with increasing cases of food poisoning. These problems can
be minimized through mobile applications and technology development. A mobile application called MyWarung©
was developed to provide an alternative, improved tool for improving food poisoning knowledge and preventive
behaviour. Methods: This cross-sectional study aims to assess the feasibility and acceptance of the MyWarung©
application for consumers in Terengganu. The 50 consumers were selected based on the inclusion and exclusion
criteria using convenience non-probability sampling. The data were collected through a questionnaire that included
three components: socio-demographic, feasible (6 components) and acceptable (7 components). The scoring above
80.0% indicates an acceptable, while lower than 80.0% show unacceptable for both feasibility and acceptability
sections. SPSS 22.0 has analyzed the data. Results: The results showed excellent feasibility with a median score
of 27.5 (IQR 6.0) out of 30.0, and acceptance with 32.0 (IQR 7.0) out of 35.0. Majority of the respondents agreed
that the app is easy to use (94.0%), easy to understand (88.0%), attractive (84.0%), catchy (88.0%), provides more
information (96.0%), efficient (96.0%), knowledge improvement (96.0%), beneficial (100.0%), useful application
(88.0%), and recommend to the other people (84.0%). The overall result showed that most respondents agreed that
MyWarung© application was feasible and acceptable with 90.0% and 86.0% feasibility and acceptability rate. Conclusion: The MyWarung© application among consumers can be highly feasible and acceptable in preventing food
poisoning during dining out.

Acute gastroenteritis (AGE) causes significant health and economic burden on society. The aim of this study is to estimate households’ direct and indirect expenditures on AGE and its predicted factors. This cross-sectional study was conducted between December 2019 and March 2020 using a bilingual proforma distributed using Survey Monkey among individuals with self-reported AGE in all 14 states of Malaysia. The finding revealed the average expenditure for a single episode of AGE was RM395.58 (± SD 798.02). The mean indirect expenditure was higher at RM259.14 (± SD 379.92) vs. direct expenditure of RM136.44 (± SD 596.47). The highest expenditure was seen among those who obtained inpatient care. The multiple linear regression analysis showed that household income (RM0.13; 95% CI: 0.01, 0.27; p=0.043) and type of healthcare facility (private vs government) (RM1842.05; 95% CI: 395.13, 3288.98; p=0.014) had a significant association with households’ total health expenditure on AGE. Acute gastroenteritis incurred substantial costs on all affected households regardless of care-seeking modalities. Interestingly, the main economic burden of AGE was the indirect cost of productivity loss; interpreted in terms of days away from work. In conclusion, AGE instigated an economic burden on both households and employers. The household income and type of facility were found to be significant factors associated with the households’ health expenditures due to AGE. This study recommends food safety awareness among the public and enforcement of safe food handling practices among food vendors and industries.

Objective: To compare the efficiency of routine diagnostic PCR assays in detecting pathogenic Leptospira isolated from water and soils. Methods: Seven routine assays targeting six genes (lipL32, flaB, gyrB, lfb1, secY and ligB) were evaluated and compared on the cultures of two groups of pathogenic Leptospira from different sources. One group included 19 described reference strains recovered from infected human or animals, and another group included 22 environmental isolates from recreational and residential sites in Malaysia. The latter have been confirmed for presence of pathogenic Leptospira DNA. PCR positivity or detection sensitivity of each assay was determined and compared between the two groups. Results: Validation on reference strains showed 100.0% PCR sensitivity for all assays except ligB-PCR (95.0%) that failed to amplify Leptospira interrogans serovar Pomona. In marked contrast, there was a notable decline in sensitivity in the environmental isolates (lipL32-PCR, 95.5%;flaB-PCR, 90.9%; gyrB-PCR, 77.3%; lfb1-PCR, 59.1%; secY-PCRs, 40.9% G1/G2-PCR, 36.4%; ligB-PCR, 13.6%), implying a large genetic distance between the two groups, as well as nucleotide polymorphism among environmental isolates. Conclusions: High proportion of false-negative PCR results suggests a need of prudent selection of primers in detecting environmental pathogenic Leptospira. These findings offer valuable insights on the extensive biodiversity of genus Leptospira and its impact on the efficacy and development of molecular detection tool.
