Introduction: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) induce clinically meaningful weight reduction in patients with type 2 diabetes mellitus (T2DM), but real-world data in Southeast Asian populations are limited. This study evaluated the effectiveness of GLP-1 RAs in achieving clinically significant weight loss in Malaysian patients with obesity and T2DM. Methodology: A retrospective cohort study was conducted among adults with T2DM and obesity attending the Endocrinology Clinic at Hospital Sultan Abdul Aziz Shah between January 2023 and December 2024. Patients receiving GLP-1 RAs (semaglutide or liraglutide) were compared with those on standard care. Anthropometric outcomes were assessed over 6–12 months, with weight loss thresholds of ≥3, ≥5, and ≥10%. Between-group comparisons used Fisher’s exact test, and odds ratios (OR) were calculated. Results: Eighty-five patients were included (GLP-1, n = 47; control, n = 38). The GLP-1 group achieved significantly higher rates of any weight loss (70.0% vs 41.2%; OR = 3.33, p = 0.019) and ≥3% weight loss (42.5% vs 14.7%; OR = 4.29, p = 0.011). Number needed to treat was 3–4 patients. Proportions achieving ≥5 and ≥10% weight loss were higher in the GLP-1 group but did not reach statistical significance. Conclusion GLP-1 RA therapy significantly improves the likelihood of clinically meaningful weight loss in Malaysian patients with obesity and T2DM. These findings support the integration of GLP-1 RAs into routine obesity management strategies in Southeast Asia.

Introduction: While Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are effective for weight reduction in type 2 diabetes mellitus (T2DM), interindividual variability exists. Lifestyle factors, particularly baseline physical activity, may modify weight loss outcomes. This study examined whether baseline activity influences GLP-1 RA efficacy in Malaysian patients. Methodology: A retrospective cohort of adults with obesity and T2DM receiving GLP-1 RAs (semaglutide or liraglutide) from January 2023 to December 2024 was analyzed. Baseline physical activity was classified as active or inactive. Primary outcomes were achievement of ≥3 and ≥5% weight loss over 6–12 months. Associations were assessed using Fisher’s exact test and logistic regression. Results: Among GLP-1-treated patients, those reporting baseline physical activity were more likely to achieve ≥3% weight loss and demonstrated trends toward higher, ≥5%, weight loss. Logistic regression suggested baseline activity increased the odds of clinically meaningful weight reduction, though statistical significance was limited by sample size. Conclusion Baseline physical activity may enhance GLP-1 receptor agonist-mediated weight loss in obese patients with T2DM. Integrating lifestyle interventions with pharmacotherapy may optimize treatment outcomes. Larger prospective studies are warranted to confirm these findings.

Feeding practices after hospital discharge are important for the growth and nutritional adequacy of preterm infants. However, local data on post-discharge milk feeding and complementary feeding practices remain limited. This study described post-discharge milk feeding practices and the timing and quality of complementary feeding among Malaysian preterm infants. An exploratory cross-sectional study was conducted among caregivers of preterm infants born before 37 weeks of gestation and aged 6–23 months corrected age. A structured online questionnaire collected information on clinical characteristics, milk feeding history, complementary feeding practices, and sociodemographic factors. Complementary feeding quality was assessed using the World Health Organization indicators: Minimum Dietary Diversity (MDD), Minimum Meal Frequency (MMF), and Minimum Acceptable Diet (MAD). Descriptive analyses were performed. Twenty-three caregivers participated. All infants received breastmilk during their NICU stay. Predominant or exclusive breastmilk feeding decreased from 60.9% at 3 months to 52.2% at 6 months, while formula feeding increased to 47.8% at 6 months. The mean (SD) corrected age at complementary feeding initiation was 5.1 (1.2) months, corresponding to 7.1 (1.4) months chronological age. More than half of the infants (52.2%) started complementary feeding before 5 months corrected age. Plain or mixed porridge was the most common first complementary food (82.6%). Overall, 65.2% achieved MDD, 70.0% achieved MMF, and 47.8% achieved MAD. Post-discharge milk feeding and complementary feeding practices varied among Malaysian preterm infants. Less than half achieved the minimum acceptable diet. Clearer pretermspecific feeding guidance and enhanced caregiver education are needed to support optimal feeding practices after hospital discharge.

Introduction: Patient health can be influenced by indoor air quality (IAQ) level, where the risks of IAQ pollution are proportionate with the occupant number in the clinic. This research aims to determine the level of IAQ in Medical Clinic 1 and 2 of University Hospital in Klang Valley, Malaysia. Methods: The indoor exposure to physical (temperature, relative humidity and air movement), chemical (formaldehyde, CO2 , CO, TVOC and PM10) and biological (bacterial and fungal count) parameters following Industry Code of Practice (ICOP) IAQ (2010) were assessed in the morning and afternoon using relevant equipment. Data was analysed with One-Sample T Test and Independent T Test using SPSS Version 25. Results: No statistically significant mean difference (p>0.05) of IAQ parameters between both Medical Clinics (morning & afternoon) except for Rh and CO by Independent T Test analysis. In contrast, the One-Sample T Test showed there was statistically significant mean difference (p<0.01) of all parameters as compared to the ICOP (2010) standard in both Medical Clinics (morning and afternoon). There was a positive correlation of CO2 , CO and formaldehyde with bacterial counts (TBC) for both Medical Clinics. Meanwhile, CH2 O concentration was slightly higher in the morning due to the usage of cleaning products which may have released CH2 O gas killing the bacteria, thus lower the rate of bacterial growth in the afternoon. Fungal counts showed no significant impact. Conclusion: All measured parameters were complied with the ICOP (2010) standard except air movement and CO2 in both Medical Clinics.

Epigallocatechin-3-gallate (EGCG) is a naturally derived compound from green tea with high antioxidant activity and various anti-cancer properties. EGCG has been widely investigated worldwide. However, effects of EGCG on cell cycle of K562 have not been clearly stated elsewhere. This study was conducted with the aim to investigate the antiproliferative effect of EGCG on K562 human leukemic cells and its underlying mechanism of action on the cells. MTT assay was conducted to determine cytotoxicity effect of EGCG on the K562 cells. Meanwhile, cell cycle analysis and DNA damage on the cells were determined by Flow cytometry and Comet assay respectively. K562 cells were treated with EGCG at concentrations ranging from 0 to 100µg/ml for 48 hours. The results showed that EGCG effectively decreased the percentage of cell viability in a dose dependent manner. The IC10, IC25 and IC50 of EGCG on K562 cell lines were 5 ± 2.44 µg/mL, 10 ± 5.93 µg/mL and 50 ± 1.93 µg/mL, respectively. In cell cycle assay, EGCG has shown no significant effect (p>0.05) on the cell cycle of K562 cell line as compared to negative control, whereas Imatinib mesylate as the positive control showed cell cycle arrest at S phase in this cell line. Hence, EGCG can be verified as a non-cell cycle specific compound. In addition, EGCG was found to cause a significant increase (p<0.05) in tail moment value and percentage of DNA tail in K562 cell line, suggesting DNA damage as an early signal of EGCG induced cell cytotoxicity. In conclusion, by decreasing the cell viability and inducing DNA damage, EGCG showed promising potential as an alternative treatment for leukemia through non-cell cycle specific pathway and further investigation on other mechanisms of action of EGCG on the cells is recommended.

Loss of teeth can affect masticatory efficiency in older adults. This may result in avoidance or modifications in foodchoices and lead to lower intake of important nutrients among older individuals. The aim of this study was to determinethe association between tooth loss and body mass index, BMI, among older adults in Kuala Pilah, Negeri Sembilan. Across-sectional study was carried out on 428 older adults aged 50 years and above from selected villages in district ofKuala Pilah. Respondents were interviewed to collect information on their demographic characteristics. Number of toothloss was determined through oral assessment, followed by anthropometric assessment to calculate the BMI of respondents.Findings showed that majority of the respondents were overweight and obese, 40.4% and 19.9% respectively, while onlya small proportion was underweight, 3.9%. The proportion of edentulism (total tooth loss) was 18.3% and majority ofthe older adults had lost more than 12 teeth (77.1%) and less than 4 pairs of occluding posterior teeth (86.0%). Totaland partial tooth loss was found to be not significantly associated with BMI. In relation to the arrangement of teeth,older adults with reduced number of posterior occluding pairs of teeth were more likely to experience unsatisfactoryBMI (OR = 3.61, 95% CI: 1.48, 8.76). This may suggest that functional arrangement of the tooth in the oral cavity is moreimportant than the number of tooth loss alone. Thus, maintaining an optimum number of teeth for chewing is essentialfor maintenance of ideal BMI.

Background: Zerumbone (ZER) is a major bioactive compound of Zingiber zerumbet,a wild ginger plant that has been documented to have anti-proliferative, anti-inflammatory andanti-oxidant properties. To investigate its hepatoprotective potential, this study was designed todetermine the treatment effects of ZER on acute hepatotoxicity induced by paracetamol (PCM) inrats.Methods: The control group was administered with phosphate buffer solution (PBS) whilethe other two groups received PCM alone (1000 mg/kg) and PCM + 25 mg/kg ZER, respectively,at 0 h and 4 h after PCM injection. After 24 h, the blood and liver were collected for differentialwhite blood cell count, liver histological observation and biochemical analysis including alanineaminotransferase (ALT), aspartate aminotransferase (AST), and total protein concentration inserum and liver.Results: Treatment with ZER was found to significantly reduce ALT (P = 0.041), AST (P =0.044) and total hepatic protein (P = 0.045) in comparison to PCM-induced rats. Rats treated withZER exhibited the normal structure of hepatocytes with no vacuolisation or necrosis and showedsignificantly reduced neutrophil count (P = 0.037). This finding suggests its ability to suppress theinflammatory processes caused by PCM overdosage and decrease the hepatocytes tendency to gothrough necrotic processes.Conclusion: ZER possessed protective activity against PCM-induced acute hepatotoxicityin a rat model.

In this study, the asymmetry of the main effects of action, background and tonal frequency during a pitch memory processingwere investigated by means of brain activation. Eighteen participants (mean age 27.6 years) were presented with low andhigh frequency tones in quiet and in noise. They listen, discriminate and recognize the target tone against the final tonein a series of four distracting tones. The main effects were studied using the analysis of variance (ANOVA) with action (towring (rubber bulb) vs. not to wring), background (in quiet vs. in noise) and frequency (low vs. high) as the factors (andlevels respectively). The main effect of action is in the right pre-central gyrus (PCG), in conformation with its contralateralbehavior. The main effect of background indicated the bilateral primary auditory cortices (PAC) and is right lateralized,attributable to white noise. The main effect of frequency is also observed in PAC but bilaterally equal and attributable tolow frequency tones. Despite the argument that the temporo-spectral lateralization dichotomy is not especially rigid asrevealed by the main effect of frequency, right lateralization of PAC for the respective main effect of background clearlydemonstrates its functional asymmetry suggesting different perceptual functionality of the right and left PAC.

A study on the isolation and identification of bacterial flora from hot spring was carried out from Bentong hot springwater, Pahang. In general, many of the bacteria identified from the hot spring were from Bacillus sp. due to its abilityto adapt to high temperature mainly by forming endospore. The objective of this study was to identify bacteria otherthan Bacillus sp. that were able to survive this hot spring. Three hot spring pools were identified as A, B and C. Thetemperatures were ranging from 36°C to 52°C and their pH values were between 7.88-8.65. The result shows thattwo species of Gram positive cocci and three species of Gram negatives were isolated. The two Gram positives wereStreptococcus sp. and Staphylococcus sp. The three species of Gram negative rods were identified as Pseudomonas sp.,Klebsiella sp. and Proteus sp. In conclusion, non-sporulating species of bacteria other than Bacillus sp. have adaptedto survive in hot spring

Pesticides and chemical fertilizers are widely used in agriculture to increase crop productivity among farmers.However, exposure to pesticides will give potential risk to human health. The aim of this study was to analyze thefrequency of micronucleus (MN) and binucleus (BNu) formation in buccal cells from farmers who were exposedto pesticides using the MN assay. Buccal swabs were collected from the farmers in Tanjung Karang (n = 32) andKelantan (n = 43) using wooden tongue depressor. A structured questionnaire was used to obtain demographic dataof the farmers. Cytogenetic analysis was carried out by Acridin Orange (AO) staining 0.0025% (w/v). The frequencyof MN and BNu as the biomarkers for cytogenetic damage was observed by using a fluorescence microscope.Comparison of frequency of MN and BNu is conducted in two areas namely Tanjung Karang, Selangor and Kelantanbecause of the agricultural activity and the type of pesticides used are different. Results showed that the frequencies of bothMN and BNu among farmers in Tanjung Karang were significantly higher (p < 0.05) compared to farmers in Kelantan.Meanwhile, for the socio-demographic factors (age, smoking status, working period), MN and BNu frequencies amongfarmers in Tanjung Karang were also significantly higher (p < 0.05) as compared to farmers in Kelantan. While in theaspect of pesticide exposure, the frequencies of MN and BNu showed no significant difference between the frequency ofpesticide spraying (p > 0.05) and the practices of PPE (Personal Protective Equipment) (p > 0.05). This may suggeststhat cytogenetic changes were not influenced by these factors. In addition, correlation study shows positive correlationbetween the frequency of MN with the pesticide exposure of farmers in Tanjung Karang (p > 0.05, r = 0.015) and Kelantan(p > 0.05, r = 0.0158). Besides, the frequency of BNu also has a positive correlation with the pesticide exposure amongfarmers in Tanjung Karang (p > 0.05, r = 0.036) and farmers in Kelantan (p > 0.05, r = 0.013). Hence, this present study demonstrated that exposure to pesticides increasedthe formation of MN and BNu among farmers and theprolonged use of pesticides may induce genotoxicity andDNA damage to human.
