Ab Manan N, Noor Aizuddin A, Hod R

Ann Glob Health, 2018 11 05;84(4):670-678.
PMID: 30779516 DOI: 10.29024/aogh.2376

IntroductionMany epidemiological studies have demonstrated associations between air pollution levels and human health in terms of hospital admissions. The aim of this paper is to gather evidence concerning air pollution effects on the risk of hospital admission. We hypothesised that increase in: particulate matter (PM), ozone (O3), carbon monoxide (CO), nitrogen dioxide (NO2), and sulphur dioxide (SO2) levels would be associated with the increasing trend of hospital admission.MethodsA systematic review of literature was carried out. Literature search was done in Sage, Ovid Medline, Science Direct, Wiley and ProQuest from 2010 to 2016 using keywords "hospital admission and air pollution". Studies of any relevant design were included if they presented original data, included at least one analysis where hospital admission was the specific outcome, and one or more of the following exposures were investigated: PM, O3, CO, NO2 and SO2.ResultsA total of 175 potential studies were identified by the search. Twenty two studies qualified for the review. Air pollution was noted to have an excessive risk of 3.46 (95%CI, 1.67, 5.27) of total hospital admissions. Cardiovascular admission was noted to have an increased risk of hospitalization for PM2.5 of 1.5 to 2.0; PM10 (1.007 to 2.7); NO2 (1.04 to 1.17) and SO2 (1.007). For respiratory admission, PM2.5 can caused an increased risk of hospitalization by 1.1 to 1.8; PM10 (1.007 to 1.13); NO2 (1.08 to 1.94) and SO2 (1.02). While O3 have minimal effect on COPD and stroke, CO does not influence in the effect of these hospitalization.ConclusionThe exposure to air pollutants confers an increased risk of admission of several disease. Our findings call for greater awareness of environmental protection and the implementation of effective measures to improve the quality of air, which may reduce the risks of adverse effects on the population's health.

BACKGROUND: Malaysia is projected to become an aged country by 2030, with the older age group comprising 10 percent of the total population. To address this demographic shift, comprehensive plans and initiatives are being implemented at various levels, ranging from the government to local communities. A crucial aspect of these efforts is community empowerment, which requires a reliable and validated tool for measurement.
OBJECTIVE: This study aimed to validate the Individual Community Related Empowerment (ICRE) scale in alignment with the national language of Malaysia.
METHODS: This cross-sectional study was conducted from May to December 2019. Back-to-back translation from the English to Malay version of the ICRE scale was done. A total of 328 older persons aged 60 years old and above who attended clinics and understood Malay had been randomly selected. Exploratory factor analysis (EFA), particularly Principal Component Analysis (PCA) with Varimax rotation and Kaiser Normalization, was performed in this study using IBM SPSS version 27 Amos graphic.
RESULTS: The findings revealed that the Malay version of the Individual Community Related Empowerment (ICRE-m) scale consists of five components: self-efficacy, intention, participation, motivation, and critical awareness, which collectively accounted for 92.3% of total variance. All five components demonstrated Cronbach's alpha values greater than 0.7, indicating the reliability of the selected items for field studies.
CONCLUSION: The ICRE-m scale is acceptable for field studies and valid for measuring individual-related community empowerment. Nurses and other healthcare professionals can employ this scale specifically within the Malay-speaking population, particularly in the Asian region. Future studies on community empowerment among older individuals can utilize this tool to assess community readiness for participating in community health interventions.
Homeostatic indices of insulin resistance among gestational diabetics in anticipating pregnancy complications

Ismail NA, Kasim MM, Noor Aizuddin A, Umar NA

Gynecol Endocrinol, 2013 Jul;29(7):691-4.
PMID: 23772780 DOI: 10.3109/09513590.2013.797398

OBJECTIVE: This was to determine HOMA-IR score as well as to assess its association in fetal and maternal outcomes among pregnant women with diabetes risks.
METHODS: A prospective cohort study of pregnant women with diabetes risks was done. GDM was diagnosed using modified glucose tolerance test. Serum insulin was taken and measured by an electrochemiluminescence immunoassay method. Plasma glucose was measured by enzymatic reference method with hexokinase. HOMA-IR score was calculated for each patient. Maternal and fetal outcomes were analyzed.
RESULTS: From 279 women recruited, 22.6% had GDM with higher HOMA-IR score (4.07 ± 2.44 versus 2.08 ± 1.12; p = 0.001) and fasting insulin (16.76 ± 8.63 µIU/L versus 10.15 ± 5.07 µIU/L; p = 0.001). Area under ROC curve for HOMA-IR score was 0.79 (95% confidence interval, 0.74-0.84) with optimum cut-off value of 2.92 (sensitivity = 63.5%; specificity = 89.8%), higher than recommended by IDF (2.38). This point showed significant association with neonatal hypoglycemia (p = 0.02) and Cesarean section (p = 0.04) in GDM mothers.
CONCLUSIONS: HOMA-IR score and insulin resistance levels were higher in GDM women in our population. With the cut-off HOMA-IR value of 2.92, neonatal hypoglycemia and Cesarean section were significant complications in GDM mothers. This can be used in anticipation of maternal and fetal morbidities.
Fulltext A systematic review on the level of risk perception of diabetes mellitus: The role of environmental factor

Jane Ling MY, Ahmad N, Noor Aizuddin A, Ja'afar MH

PLoS One, 2024;19(7):e0308152.
PMID: 39078862 DOI: 10.1371/journal.pone.0308152

BACKGROUND: Risk perception plays important role in motivating preventive health behaviours. The objective of this systematic review was to explore the level of diabetes risk perception among individuals with and without apparent risk for diabetes, and to consider the effect of environmental factors on the level of diabetes risk perception.
METHODS: This systematic review was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The literature search was carried out through PubMed, Web of Science, and Scopus. Original articles written in English and published between 2013 and 2023 were considered. Study quality was appraised using the Mixed Methods Appraisal Tool. Narrative synthesis was undertaken due to methodological heterogeneity in the included studies.
RESULTS: A total of 13 cross-sectional studies, two randomized controlled trials, two cohort studies, two mixed methods studies and one quasi-experiment with a control group were included. An overall low level of diabetes risk perception was reported particularly in those without apparent risk for diabetes. The 20 included studies reported widely varied measures for calculating diabetes risk perception. The influence of environmental factors on the risk perception of diabetes was highlighted.
LIMITATIONS: The use of study-specific and non-validated measures in the included studies weakens the authors' ability to compare across studies. The role of language and publication bias within this systematic review should be acknowledged as we included only English-language studies published in peer-reviewed journals. Another limitation is the exclusion of dimensions of risk perception such as optimistic bias as search terms.
CONCLUSION: The overall low risk perception of diabetes calls for urgent need of public health interventions to increase the risk perception of diabetes. In the future, researchers should ensure the validity and reliability of the measures being used. The influence of environmental factors on the diabetes risk perception indicates that diabetes preventive interventions targeting environmental factors may be effective in increasing the risk perception of diabetes.

Accumulating data indicates that enhancer of zeste homology 2 (EZH2) and isocitrate dehydrogenase 1 (IDH1) are implicated in promoting tumourigenesis in a myriad of malignancies including gliomas. We aimed to determine the immunoexpression of EZH2 in gliomas and its correlation with clinicopathological variables. The prognostic value of the combined immunoexpression of EZH2 and IDH1 was further explored in a retrospective analysis involving 56 patients with histologically confirmed gliomas in Universiti Kebangsaan Malaysia Medical Centre from 2010 to 2016. The patients were then followed up for a period of five years. EZH2 and IDH1 R132H immunoexpressions were performed and analysed on respective tissue blocks. Five-year progression-free survival (PFS) and overall survival (OS) were estimated by Kaplan−Meier analysis. Univariate and multivariate Cox proportional hazard regression models were performed to evaluate the value of EZH2 as an independent factor for the prediction of PFS and OS. High EZH2 immunoexpression was demonstrated in 27 (48.2%) gliomas. High EZH2 expression was significantly correlated with older age (p = 0.003), higher tumour grade (p < 0.001), negative IDH1 R132H immunoexpression (p = 0.039), a poor 5-year PFS (mean = 9.7 months, p < 0.001) and 5-year OS (mean = 28.2 months, p = 0.007). In IDH1 R132H-negative gliomas, there was a trend toward shorter 5-year PFS (mean = 8.0 months, p = 0.001) and 5-year OS (mean = 28.7 months, p = 0.06) in gliomas demonstrating high EZH2 expression compared with those with low EZH2 expression. High EZH2 immunoexpression is an unfavourable independent prognostic predictor of poor survival in gliomas. EZH2 analysis might therefore be of clinical value for risk stratification, especially in patients with IDH1 R132H-negative gliomas.
