Prevalence of type 2 diabetes mellitus and impaired fasting glucose, and their associated lifestyle factors among teachers in the CLUSTer cohort.

Background: Teachers are responsible for educating future generations and therefore play an important role in a country's education system. Teachers constitute about 2.6% of all employees in Malaysia, making it one of the largest workforces in the country. While health and well-being are crucial to ensuring teachers' work performance, reports on non-communicable diseases such as type 2 diabetes mellitus (T2DM) among Malaysian teachers are scarce. Hence, this study focused on the prevalence of T2DM, undiagnosed diabetes mellitus (DM), impaired fasting glucose (IFG), and underlying lifestyle factors associated with these outcomes among Malaysian teachers. Methods: This is a cross-sectional study from the CLUSTer cohort. There were 14144 teachers from the Peninsular Malaysia included in this study. The teachers' sociodemographic and lifestyle characteristics were described using a weighted complex analysis. A matched age group comparison was carried out between teachers and the Malaysian general population on T2DM, undiagnosed DM, and IFG status. Next, the researchers examined the association of lifestyle factors with T2DM and IFG using multivariable logistic regression. Results: The prevalence of T2DM, undiagnosed DM, and IFG among the Malaysian teachers were 4.1%, 5.1%, and 5.6%, respectively. The proportions of teachers with T2DM (both diagnosed and undiagnosed) and the IFG increased linearly with age. Teachers had a lower weighted prevalence of T2DM (known and undiagnosed) than the general population. However, teachers were more inclined to have IFG than the general population, particularly those aged 45 years and older. Among all lifestyle indicators, only waist circumference (aOR: 1.14, 95% CI: 1.08, 1.20) was found to be associated with T2DM, whereas waist circumference (aOR: 1.10, 95% CI: 1.05, 1.15) and physical activity [moderately active = (aOR: 0.71, 95% CI: 0.52, 0.98); highly active = (aOR: 0.56, 95% CI: 0.40, 0.80)] were associated with IFG. Conclusions: Modifiable lifestyle factors such as abdominal obesity and physical activity were associated with T2DM and IFG. Intervention programs targeting these factors could help reduce future treatment costs and increase productivity.

Association of Serum Beta-Carotene with Metabolic Risk Factors among a Work Cohort in Malaysia.

Metabolic syndrome (MetS) poses increased risks for non-communicable diseases, increasing all-cause mortality, disability, and healthcare costs. Beta-carotene as the major carotenoid is identified to play an important role in the pathophysiology of MetS. The present study aimed to investigate the association between serum beta-carotene levels with metabolic syndrome and metabolic risk factors among a cohort of teachers in Peninsular Malaysia. This cross-sectional study investigated a sub-sample of 645 serum samples which were randomly selected for beta-carotene determination. Socio-demographic, lifestyle and metabolic risk factors were measured following standard protocols. There were equal proportions of males and females, with majority Malays (69%) followed by the Chinese (24%) and Indians (6.5%). The prevalence of MetS was 24.8% with abnormal waist circumference and high blood pressure as the most commonly reported metabolic risk factors. The median serum beta-carotene was 5.15 (5.07) µmol/L. Serum beta-carotene in the lowest quartile (Q1) was found to be significantly associated with MetS (OR: 5.81; 95% CI: 2.96, 11.38) and metabolic risk factors, namely triglycerides (OR: 6.38; 95% CI: 3.04, 13.35), fasting blood sugar (OR: 3.32; 95% CI: 1.48, 7.43), HDL-cholesterol (OR: 2.88; 95% CI: 1.58, 5.26) and waist circumference (OR: 2.94; 95% CI: 1.73, 5.01), after adjusted for potential confounders. In summary, participants with lower serum beta-carotene had higher odds for MetS and the above-mentioned metabolic risk factors.

Perception towards E-learning and COVID-19 on the mental health status of university students in Malaysia.

The COVID-19 pandemic has disrupted the lives of all including university students. With the preventive measures to reduce the transmission of COVID-19, all face-to-face teaching and learning are converted to e-learning. The COVID-19 pandemic and the implementation of e-learning may influence these students' mental conditions. This study aimed to determine the association of factors with mental health status (depression, anxiety and stress) among university students in Malaysia. Study participants were tertiary education students from both the private and public universities in Malaysia. Participants were recruited via university emails and social media. The survey was administered via the online REDCap platform, from April to June 2020, during the movement control order period in the country. The questionnaire captured data on socio-demographic characteristics, academic information, implementation of e-learning, perception towards e-learning and COVID-19; as well as DASS 21 to screen for depression, anxiety and stress. The levels of stress, anxiety and depression were 56.5% (95% CI: 50.7%, 62.1%), 51.3% (95% CI: 45.6%, 57.0%) and 29.4% (95% CI: 24.3%, 34.8%) respectively. Most participants had good perception towards e-learning but negative perception on COVID-19. From the multivariate analysis, participants with positive perception on COVID-19 were protective towards stress (aOR: 0.96; 95% CI: 0.92, 0.99), anxiety (aOR: 0.94, 95% CI: 0.90, 0.98) and depression (aOR: 0.95; 95% CI: 0.91, 0.99). Older students were 14% (aOR: 0.86, 95% CI: 0.79, 0.94) and 11% (aOR: 0.89: 95% CI: 0.80, 0.99) less likely for anxiety and depression, respectively. Students originated from the Malay ethnicity had higher odds (aOR: 1.93; 95% CI: 1.05, 3.56) for depression. These findings demonstrated that the mental status of university students was greatly affected during the COVID-19 pandemic. Timely and credible information should be disseminated to alleviate their negative perception towards COVID-19.

Religious Coping, Depression and Anxiety among Healthcare Workers during the COVID-19 Pandemic: A Malaysian Perspective.

Anxiety and depression have been prevalent among Healthcare Workers (HCWs) amidst the COVID-19 pandemic. This study aims to evaluate the prevalence of anxiety and depression among HCWs amid the pandemic and their association with religious coping. A cross-sectional study design was applied. The scales utilized were Malay versions of the Brief Religious Coping Scale (Brief RCOPE M) and Hospital Anxiety and Depression Scale (HADS M). In total, 200 HCWs were recruited. HCWs scored higher in positive religious coping (mean: 21.33) than negative religious coping (mean: 10.52). The prevalence of anxiety and depression was 36.5% and 29.5%. Both positive and negative religious coping were significantly associated with anxiety (p < 0.01) and depression (p < 0.05, p < 0.01). Positive coping predicted reduction in anxiety (adjusted b = -0.15, p = 0.001) and log-transformed depression score (adjusted b = -0.019, p = 0.025). Negative coping predicted increment of anxiety (adjusted b = 0.289, p < 0.001) and log-transformed depression score (adjusted b = 0.052, p < 0.001). Positive religious coping is vital in reducing anxiety and depression among HCWs amid the pandemic. Strategies which increase positive religious coping and reduce negative religious coping must be emphasized to boost mental health among HCWs.

Short communication: Genetic variants of Sarcocystis cruzi in infected Malaysian cattle based on 18S rDNA.

Sarcocystis species are pathogenic parasites that infect a wide range of animals, including cattle. A high prevalence of cattle sarcocystosis has been reported worldwide, but its status is unknown in Malaysia. This study focused on utilizing 18S rDNA to identify Sarcocystis species in Malaysian cattle and to determine their genetic variants. In this study, only Sarcocystis cruzi was detected in Malaysian cattle. The intra-species S. cruzi phylogenetic tree analysis and principal coordinate analysis (PCoA), respectively displayed two minor groups among the parasite isolates. This finding was supported by high Wright FST value (FST=0.647). The definitive hosts (dogs) may play a fundamental role in the development of S. cruzi genetic variants. Additionally, the existence of microheterogeneity within the S. cruzi merozoites and/or distinct genetic variants arisen from independent merozoites in mature sarcocysts, possibly contributed to the existence of intra-species variations within the population.

Modified use of methylene blue in the tissue compression technique to detect sarcocysts in meat-producing animals.

Sarcocystosis in meat-producing animals is a major cause of reduced productivity in many countries, especially those that rely on agriculture. Although several diagnostic methods are available to detect sarcocystosis, many are too time-consuming for routine use in abattoirs and meat inspection centers, where large numbers of samples need to be tested. This study aimed to compare the sensitivity of the methylene blue tissue preparation, unstained tissue preparation and nested PCR in the detection of sarcocysts in tissue samples. Approximately three-fold more sarcocysts were detected in methylene blue-stained tissue compared to unstained controls (McNemar's test: P<0.01). Test sensitivity was comparable to that of the gold standard for sarcocyst detection, nested polymerase chain reaction. These results suggest that methylene blue can be used in tissue compression as a rapid, safe, and inexpensive technique for the detection of ruminant sarcocystosis in abattoirs.

Genetic assemblage of Sarcocystis spp. in Malaysian snakes.

BACKGROUND: Sarcocystis species are protozoan parasites with a wide host range including snakes. Although there were several reports of Sarcocytis species in snakes, their distribution and prevalence are still not fully explored. METHODS: In this study, fecal specimens of several snake species in Malaysia were examined for the presence of Sarcocystis by PCR of 18S rDNA sequence. Microscopy examination of the fecal specimens for sporocysts was not carried as it was difficult to determine the species of the infecting Sarcocystis. RESULTS: Of the 28 snake fecal specimens, 7 were positive by PCR. BLASTn and phylogenetic analyses of the amplified 18S rDNA sequences revealed the snakes were infected with either S. nesbitti, S. singaporensis, S. zuoi or undefined Sarcocystis species. CONCLUSION: This study is the first to report Sarcocystis infection in a cobra, and S. nesbitti in a reticulated python.
