Introduction: The prevalence of diabetes mellitus (DM) in Malaysia is drastically increasing. Subjects with DM are
more likely to have deranged liver function tests (LFT). This study aimed to determine the prevalence of abnormal liver enzymes [(alanine aminotransferase (ALT) and alkaline phosphatase (ALP)] and its associated factors among type
2 DM (T2DM) subjects visiting a referral diabetic clinic in a tertiary government hospital. Methods: This retrospective, cross-sectional study included electronic data of 300 T2DM subjects ≥18 years old in the outpatient specialist
clinic from January 2011 to December 2014. Statistical analysis was performed using SPSS version 22. Results: The
study population at large included Malays, of age >60 years with comparable gender percentage. Most subjects had
long-standing DM, poor glycaemic control and were on treatment. The prevalence of abnormal ALT and ALP was
27.3% and 13%; with 90.2% and 97.4% having mild ALT and ALP elevations, respectively. Significant associations
noted for age, body mass index (BMI) and duration of T2DM for ALT whereas for ALP, anti-diabetic medication was
significant between groups of normal and abnormal levels. Deranged liver enzymes were associated significantly
with dyslipidaemia. Conclusion: Our study on the crude prevalence of raised liver enzymes may help identify T2DM
patients at increased risk of non-alcoholic fatty liver disease (NAFLD). Modification of metabolic risk factors, such
as weight loss, control of dyslipidaemia rather than just tighter glycaemic control should be emphasised to reduce
morbidity and mortality. Liver enzymes remain a simple and non- invasive marker of liver pathology in daily medical
practice.

This analytical cross-sectional study examined the nutrient intakes, dietary compliance, dietary supplementation and traditional remedy usage in type 2 diabetes mellitus (T2DM) patients from selected tertiary hospitals in multi-racial Malaysia. We compared the different characteristics of T2DM patients with and without cardiovascular disease (CVD). Socio-demographic status, dietary intakes, dietary supplementation, traditional remedy use, medical history, anthropometric measurements and clinical characteristics were obtained from face-to-face interviews. A total of 313 patients who were treated for T2DM participated in this study, in which 36.1% of them had CVD. The mean age of study subjects was 55.7 ± 9.2 years; mean diabetes duration was 10.1 ± 8.1 years; 52.1% were females; and 47.0% were Malays. The mean total energy intake of the subjects was 1674 ± 694 kcal/day, and patients with CVD consumed higher total calories (p = 0.001). Likewise, the mean carbohydrate, protein and total fat intake of CVD patients were significantly higher than non-CVD patients (p < 0.05), while mean intakes of cholesterol, fibre, minerals and all vitamins were comparable between CVD and non-CVD patients. Regardless of CVD status, a notably high proportion of the subjects did not meet the recommendations of the Medical Nutrition Therapy Guidelines for Type 2 Diabetes for total energy, carbohydrate, protein, total fat, and fibre intakes. Meanwhile, 52.4% used at least one dietary supplement and 12.1% took single traditional remedy or in various combinations. Traditional remedies and supplement intake did not differ between CVD and non-CVD subjects. It is suggested that T2DM patients should be educated based on their personalized dietary intake, dietary supplementation and traditional remedy usage. The recommendations for T2DM patients shall be met to achieve the optimal metabolic goals and minimize the potential diabetic complications.

BACKGROUND: Type 2 diabetes mellitus is a major health threat worldwide. Cosmos caudatus is one of the medicinal plants used to treat type 2 diabetes. Therefore, this study aims to determine the effectiveness and safety of C. caudatus in patients with type 2 diabetes. Metabolomic approach will be carried out to compare the metabolite profiles between C. Caudatus treated diabetic patients and diabetic controls.
METHODS AND DESIGN: This is a single-center, randomized, controlled, two-arm parallel design clinical trial that will be carried out in a tertiary hospital in Malaysia. In this study, 100 patients diagnosed with type 2 diabetes will be enrolled. Diabetic patients who meet the eligibility criteria will be randomly allocated to two groups, which are diabetic C. caudatus treated(U) group and diabetic control (C) group. Primary and secondary outcomes will be measured at baseline, 4, 8, and 12 weeks. The serum and urine metabolome of both groups will be examined using proton NMR spectroscopy.
DISCUSSION: The study will be the first randomized controlled trial to assess whether C. caudatus can confer beneficial effect in patients with type 2 diabetes. The results of this trial will provide clinical evidence on the effectiveness and safety of C. caudatus in patients with type 2 diabetes.

Tan MC, Ng OC, Yap RYP, Pan Y, Chieng JY

Malaysian Journal of Public Health Medicine, 2017;17(1):33-37.

Fecal occult blood test (FOBT) screening has been shown to decrease the incidence and mortality of colorectal cancer (CRC). The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the immunochemical fecal occult blood test (i-FOBT) in diagnosing CRC were assessed among the patients in a tertiary referral hospital in Malaysia. A total sample of 814 patients aged 16 to 85 years old who performed i-FOBT and endoscopic screenings was obtained. The patients were recruited for a retrospective investigation. Sensitivity, specificity, PPV, and NPV were derived for the CRC screenees. Out of the 814 patients screened using i-FOBT, half of them were above 59 years old (49.6%), and 36% had positive i-FOBT. Gender distribution was almost equal, where 53.4% of the patients were female, and 46.6% were male. Majority of the patients were Malays (56.6%), followed by Chinese (24.0%), Indians (16.5%), and others (2.9%). Among the 71 patients referred for colonoscopy, 57.7% and 42.3% corresponded to positive and negative i-FOBT cases, respectively. Polyps were found to be most common among the patients (25.6%), 7.0% were found positive for invasive CRC, and 35.2% had normal colonoscopic findings. There was a significant association between colonoscopic finding and positive i-FOBT (p=0.001). The sensitivity, specificity, PPV, and NPV for CRC detection were 66.7%, 43.0%, 9.8%, and 93.3%, respectively. The results indicate that i-FOBT is a useful tool in the detection of abnormalities in the lower gastrointestinal tract and therefore serves as a cornerstone for potential large-scale screening programmes.

PMID: 24763837

INTRODUCTION: The aim of this study was to evaluate the health-related quality of life (HRQoL) of Malaysian patients with type 2 diabetes mellitus (T2DM) who have cardiovascular disease (CVD), as well as identify the determinants of HRQoL among this cohort of patients.

METHODS: This study was an analytical cross-sectional study involving 313 patients aged 30-78 years (150 men, 163 women; mean age 55.7 ± 9.2 years) who were diagnosed with T2DM (mean duration of T2DM 10.1 ± 8.1 years) at two tertiary Malaysian government hospitals. The patients' sociodemographic, lifestyle, clinical and laboratory data were collected prospectively from medical records and via face-to-face interviews. HRQoL was assessed using the 15D instrument - a generic, 15-dimensional and standardised measure of HRQoL that can be used as both a profile and a single index score measure.

RESULTS: T2DM patients with CVD were found to have significantly lower 15D HRQoL scores than their nonCVD counterparts (p < 0.001). The HRQoL of T2DM patients with CVD was significantly lower than those without CVD (p < 0.05) in all of the 15 dimensions of the 15D instrument. Multinomial logistic regression analysis using backward stepwise method revealed a significant association between CVD and impaired HRQoL (odds ratio [OR] 11.746, 95% confidence interval [CI] 4.898-28.167). Age (OR 1.095, 95% CI 1.054-1.137), duration of T2DM (OR 1.085, 95% CI 1.032-1.140), ethnicity (OR 0.411, 95% CI 0.187-0.903), body mass index (OR 1.074, 95% CI 1.006-1.148), and physical activity level (OR 3.506, 95% CI 1.415-8.689) were also significant predictors of HRQoL.

CONCLUSION: In T2DM patients, the presence of CVD was significantly associated with a lower HRQoL. Therefore, the importance of tertiary prevention to minimise the potential deterioration of the HRQoL of T2DM patients with CVD should be highly emphasised.

INTRODUCTION: The incidence of type 2 diabetes mellitus is increasing worldwide. The literature suggests that acupuncture is a possible complementary therapy for type 2 diabetes mellitus. This study aims to determine the effectiveness of acupuncture as an adjunctive therapy on homeostasis model assessment-insulin resistance (HOMA-IR), and health-related quality of life (HRQoL) in patients with type 2 diabetes mellitus.
MATERIALS AND METHODS: This randomized, double-blind, placebo controlled, and parallel design trial will be carried out in a public university teaching hospitals in Malaysia. Eligible type 2 diabetes mellitus subjects will be randomly assigned to receive either acupuncture (n = 30) or a placebo (n = 30). The intervention is carried out using press needle or press placebo on abdomen area (10 sessions of treatment). Both groups will continue with their routine diabetes care. Primary outcome of HOMA-IR will be measured at the time of recruitment (-week 0), and after completion of 10 sessions (week 7) of the treatment. Additionally, secondary outcome of HRQoL will be measured at the time of recruitment (-week 0), after completion of 5 sessions (week 3/4), and 10 sessions (week 7) of the treatment. Any adverse event will be recorded at every visit.
DISCUSSION: The findings of this study will provide important clinical evidence for the effect of acupuncture as adjunctive therapy on HOMA-IR, adiposity and HRQoL of type 2 diabetes mellitus.

Objectives. Optimizing glycemic control is crucial to prevent type 2 diabetes related complications. Cosmos caudatus is reported to have promising effect in improving plasma blood glucose in an animal model. However, its impact on human remains ambiguous. This study was carried out to evaluate the effectiveness of C. caudatus on glycemic status in patients with type 2 diabetes. Materials and Methods. In this randomized controlled trial with two-arm parallel-group design, a total of 101 subjects with type 2 diabetes were randomly allocated to diabetic-ulam or diabetic controls for eight weeks. Subjects in diabetic-ulam group consumed 15 g of C. caudatus daily for eight weeks while diabetic controls abstained from taking C. caudatus. Both groups received the standard lifestyle advice. Results. After 8 weeks of supplementation, C. caudatus significantly reduced serum insulin (-1.16 versus +3.91), reduced HOMA-IR (-1.09 versus +1.34), and increased QUICKI (+0.05 versus -0.03) in diabetic-ulam group compared with the diabetic controls. HbA1C level was improved although it is not statistically significant (-0.76% versus -0.37%). C. caudatus was safe to consume. Conclusions. C. caudatus supplementation significantly improves insulin resistance and insulin sensitivity in patients with type 2 diabetes.

Metabolic syndrome (MetS) is common among patients with type 2 diabetes mellitus (T2DM) and increases the risk of cardiovascular disease (CVD) and all-cause mortality. The objective of this study was to investigate the association between the components of MetS and the prevalence of CVD among patients with T2DM. We studied 313 patients aged > or = 30 years diagnosed with T2DM at two tertiary care hospitals. Patients were recruited by systematic random sampling. Clinical data was obtained using an interviewer-administered structured questionnaire and from a review of their medical records. MetS was diagnosed using NCEP ATP III, WHO, IDF and the new Harmonized definitions. Specific MetS components such as BMI, waist circumference, waist-to-hip ratio, hypertension, HDL-C and triglyceride levels were evaluated to determine if they had an association with CVD. Thirty-six point one percent of the subjects had CVD. The mean age of the subjects was 55.7 +/- 9.2 years and the mean duration of having diabetes was 10.1 +/- 8.1 years. The overall prevalences of MetS (> or = 3 of 5 components) (95% CI) were 96.1% (94.0-98.3), 95.8% (93.6-98.1), 84.8% (80.8-88.9) and 97.7% (96.1-99.4) using NCEP ATP III, WHO, IDF and Harmonized definitions, respectively. Patients with MetS had a higher prevalence of CVD using NCEP ATP III (98.2% vs 93.5%), WHO (98.2% vs 93.0%), IDF (87.6% vs 82.0%) and Harmonized criteria (98.2% vs 96.0%). The greater the number of MetS components, the greater the chance of having CVD using three definitions for diagnosing MetS: WHO, IDF and Harmonized (p < 0.05). MetS and the combination of the individual components of MetS were significantly associated with CVD among type 2 diabetic patients in Malaysia. Aggressive treatment of MetS components is required to reduce cardiovascular risk in T2DM.

Research has proven that aerobic exercise improves glucose homeostasis among patients with type 2 diabetes mellitus (T2DM). Elastic resistance (tube or band) is suggested as a good alternative for home-based strength training among older adults including those with T2DM due to its low cost, simplicity, portability, and versatility. This study aimed to measure the effects of 16-week home-based progressive resistance training (PRT), using a resistance tube on glucose homeostasis and cardiovascular risk factors among older adults with T2DM. A total of 70 participants aged 61.68 (5.50) years with T2DM were assigned to the intervention (n = 35) and control (n = 35) groups in this quasi-experimental trial. The intervention group underwent 16 weeks of home-based PRT using a resistance tube. Significant improvements in HbA1c (-1.34% point, p < 0.001), fasting blood glucose (-1.30 mmol/L, p < 0.001), and systolic blood pressure (-1.42 mmHg, p < 0.05) were observed after 16 weeks of intervention. However, no significant changes were observed in lipid profile, diastolic blood pressure, resting heart rate, and ankle-brachial index. The finding suggests that 16 weeks of home-based PRT using a resistance tube has the potential to improve glycemic control and reduce systolic blood pressure among older adults with T2DM and caused no adverse events.
