A nutritional status survey of Orang Asli (Aboriginal) adults in Lembah Belum, Grik, has been conducted involving a total of 138 subjects. Jahai (58.7%) was the main ethnic group as compared to that of Temiar (41.3%). Based on the Body Mass Index (BMI) characteristics, the majority (63.2%) of the respondents were normal, 26.7% underweight and 10.1% were either overweight or obese. However, by using two different indices of waist circumference and waist-to-hip ratio, 1.6% and 10.8% of the total respondents revealed abdominal obesity, respectively. Measurement of mid upper arm muscle circumference (MUAMC) indicated that about 40% showed nutritional insufficiency whereas 0.8% showed over-nutrition. Body fat classification revealed that 53.4% of the respondents were thin, 45.8% at normal level and only 0.8% were obese. Student's t-test revealed a significant difference in anthropometric indices of body weight, height, MUAMC, triceps, sub-scapular, supra-iliac and body fat according to gender. Meanwhile, analysis of variance (ANOVA) showed significant differences in body weight, waist circumference, WHR and body fat according to different age categories. It was also found that those who smoked had lower BMI compared with non-smokers. Alcohol consumption was associated with higher BMI and WHR among the respondents. Pearson's correlation test between anthropometric measurements and socio-economic and demographic factors showed that ethnic group was the strongest variable.
Currently, type 2 diabetes mellitus (T2D) has emerged as global burden disease. Herbal drugs with antidiabetic activities are attracting the attention. Madecassoside and catalpol are herbal compounds having strong antioxidant and glucose lowering activity. Madecassoside and catalpol were investigated for their effect on insulin sensitivity using pancreatic INS-1E cells. Cytotoxicity of these compounds was evaluated by MTT assay. Glucose-stimulated insulin secretion (GSIS) and expression of insulin signalling proteins were studied in presence of madecassoside and catalpol. Results revealed that madecassoside and catalpol enhanced the GSIS without cytotoxic effect. Madecassoside (30 µM) and catalpol (40 µM) increased the insulin secretion in response to high glucose (16.7 mM) stimulation. Subsequently, madecassoside and catalpol showed elevated expression of p-IRS-1, Akt, and p-Akt proteins. Madecassoside and catalpol after 24 h of incubation in pancreatic INS-1E cells with high glucose concentration (30 mM) ameliorated the insulin secretion.
Cardiac arrest during scoliosis surgery is rare in idiopathic scoliosis. We present a case of cardiorespiratory collapse during corrective surgery in a young patient with idiopathic scoliosis. A diagnosis of venous air embolism was made by exclusion. A cardiorespiratory resuscitation was performed in supine position. Patient recovered without any sequelae and had operation completed 6 weeks later.
