To determine the prevalence of metabolic syndrome (MetS) in Malaysian type 2 diabetic patients using WHO, NCEP ATP III, IDF and the new Harmonized definitions, and the concordance between these definitions. This study involved 313 patients diagnosed with type 2 diabetes mellitus (T2DM) at two Malaysian tertiary hospitals. Socio-demographic data were assessed using a pre-tested interviewer-administered structured questionnaire. Anthropometric measurements were carried out according to standard protocols. Clinical and laboratory characteristics were examined. Kappa () statistics were used for the agreement between the four MetS definitions. The overall prevalence rates of MetS (95% CI) were 95.8% (93.6 -98.1), 96.1% (94.0 -98.3), 84.8% (80.8 -88.9) and 97.7% (96.1-99.4) according to the WHO, NCEP ATP III, IDF and the Harmonized definitions, respectively. The Kappa statistics demonstrated a slight to substantial agreement between the definitions ( = 0.179 -0.875, p < 0.001), where the WHO criteria revealed the highest concordance with the NCEP ATP III definition ( = 0.875, p < 0.001). The WHO against NCEP ATP III criteria evinced the highest sensitivity (99.66%) whereas Harmonized criteria against all the other three definitions showed the highest specificity (100%) in identifying MetS. In conclusion, the new Harmonized criteria established the highest prevalence of MetS among the four definitions applied. There was a very good concordance between the WHO and NCEP ATP III criteria. The extremely high prevalence of MetS observed in type 2 diabetic patients indicates an impending pandemic of CVD risk in Malaysia. Aggressive treatment of MetS components is required to reduce cardiovascular risk in T2DM.

Summary The prevalence of pre‐diabetes and of type 2 diabetes mellitus is increasing. Preventing disease progression is important to improve outcomes. Natural products are becoming popular alternatives to pharmaceutical products for preventative health and treatment of disease; however, the evidence to support the use of natural alternatives for pre‐diabetes and type 2 diabetes is lacking. Two such natural medicines include alpha‐cyclodextrin (marketed as FBCx), a fibre derived from corn starch that has been found to bind triglycerides in the intestines to prevent its absorption, aiding weight maintenance and lipid control, and hydrolysed ginseng extract (marketed as GINST15), a formula containing high amounts of Compound K, a metabolite of ginsenosides thought to be an active ingredient contributing to the anti‐hyperglycaemic effects of ginseng. This paper describes the rationale and design of a 12‐month randomized controlled trial to investigate the metabolic effects of these two products in people with pre‐diabetes and overweight or obesity. A total of 400 participants will be randomized to one of four groups (FBCx + GINST15, FBCx + placebo, placebo + GINST15, placebo + placebo) for 6 months, followed by 6 months of follow‐up. Participants will also receive lifestyle advice for healthy eating and weight loss. Data collected during the trial will include weight, waist circumference, body composition and blood pressure. Blood samples will also be collected to measure lipid profile and glycaemia. If the products are found to improve lipid and glucose levels, it will provide evidence for their use in people with pre‐diabetes to help reduce the risk of progression to type 2 diabetes.

Background and Objectives: Cognitive performance is essential for children, given this is a critical stage of brain growth and development. This systematic review and meta-analysis aimed to ascertain if physical activity or micronutrients impact cognitive performance in children. Materials and Methods: Electronic databases (PubMed and Scopus®) were searched for relevant articles published between 2012 and 2021. We emphasized randomized controlled trials (RCTs) that examined the effect of physical activity and micronutrients on cognitive performance. Data from eligible studies were gathered and evaluated using random-, fixed- or pooled-effects models with 95% confidence intervals (95% CI). Results: Physical activity appeared to improve both Mathematics (d = 1.12, 95% CI: 0.56, 1.67) and attention (d = 0.65, 95% CI: 0.15, 1.14) performances. The micronutrient vitamin B12 had a positive effect on Mathematics (d = 2.39, 95% CI: 0.79, 3.98), English (d = 5.29, 95% CI: 2.76, 7.83), Geography (d = 5.29, 95% CI: 2.76, 7.83), Science (d = 3.39, 95% CI: 2.62, 4.16) and Arts (d = 3.32, 95% CI: 1.84, 4.79). Zinc was found to positively affect English (d = 3.78, 95% CI: 0.44, 7.13), Geography (d = 4.77, 95% CI: 0.56, 8.98) and Arts (d = 2.39, CI: 0.33, 4.45). Iron positively affected Mathematics (d = 1.29, 95% CI: 0.54, 2.06), English (d = 1.29, 95% CI: 0.44, 7.13), Geography (d = 4.77, 95% CI: 0.56, 8.98) and Arts (d = 2.39, 95% CI: 0.33, 4.45). Conclusions: A more comprehensive intervention with a specific dose/level of physical activity, an increased range of cognitive performance, and a well-designed study design that accounts for dietary intake and other health outcomes are required for future studies.
