Association between the number of chondrocytes of lumbar intervertebral discs and age, abdominal aorta atherosclerosis and lumbar artery arteriosclerosis , a descriptive cross sectional study
(OMICS International, 2015) Karunanayake, A.L.; Gupta, A.
Background: The effect of age, atherosclerotic changes of abdominal aorta and arteriosclerotic changes of lumbar arteries on number of chondrocytes of lumbar intervertebral discs has not been studied. Methods: A descriptive cross sectional post mortem study was carried out in Faculty of Medicine, University of Kelaniya, Sri Lanka to determine the association between the mean number of chondrocytes in the fifth lumbar intervertebral disc and age, the level of atherosclerotic changes of the lumbar abdominal aorta and arteriosclerotic changes of right and left, fourth lumbar arteries. The presence or absence of atherosclerotic plaques in the abdominal aorta lumbar region was studied. To assess arteriosclerotic changes, the Intima Media thickness (IMT) and the total thickness (TT) of lumbar arteries were measured and the ratio IMT/TT was calculated. Bivariant analysis and a multi variant analysis were done. Results: There were 51 samples in total. Their ages ranged from 18 to 96 years. The mean age (SD) was 43 (± 17.1) years. The samples were obtained from 38 males and 13 females. There was no significant association between atherosclerotic changes of abdominal aorta and arteriosclerotic changes of lumbar arteries and the mean number of chondrocytes. Conclusion: Only the age had a significant negative association with the mean number of chondrocytes of the intervertebral disc

Policy implementation and recommended actions to create healthy food environments using the healthy food environment policy index (Food-EPI): a comparative analysis in South Asia
(Elsevier Ltd, 2024) Pineda, E.; Atanasova, P.; Wellappuli, N.T.; Kusuma, D.; Herath, H.; Segal, A.B.; Vandevijvere, S.; Anjana, R.M.; Shamim, A.A.; Afzal, S.; Akter, F.; Aziz, F.; Gupta, A.; Hanif, A.A.; Hasan, M.; Jayatissa, R.; Jha, S.; Jha, V.; Katulanda, P.; Khawaja, K.I.; Kumarendran, B.; Loomba, M.; Mahmood, S.; Mridha, M.K.; Pradeepa, R.; Aarthi, G.R.; Tyagi, A.; Kasturiratne, A.; Sassi, F.; Miraldo, M.
BACKGROUND The increasing prevalence of diet-related non-communicable diseases (NCDs) in South Asia is concerning, with type 2 diabetes projected to rise to 68%, compared to the global increase of 44%. Encouraging healthy diets requires stronger policies for healthier food environments.METHODS This study reviewed and assessed food environment policies in Bangladesh, India, Pakistan, and Sri Lanka from 2020 to 2022 using the Healthy Food Environment Policy Index (Food-EPI) and compared them with global best practices. Seven policy domains and six infrastructure support domains were considered, employing 47 good practice indicators to prevent NCDs. Stakeholders from government and non-governmental sectors in South Asia (n = 148) were invited to assess policy and infrastructure support implementation using the Delphi method.FINDINGS Implementation of food environment policies and infrastructure support in these countries was predominantly weak. Labelling, monitoring, and leadership policies received a moderate rating, with a focus on food safety, hygiene, and quality rather than obesity prevention. Key policy gaps prioritized for attention included front-of-pack labelling, healthy food subsidies, unhealthy food taxation, restrictions on unhealthy food promotion, and improvements in school nutrition standards to combat NCDs.INTERPRETATION Urgent action is required to expand food policies beyond hygiene and food security measures. Comprehensive strategies targeting NCD prevention are crucial to combat the escalating burden of NCDs in the region.
Reference equations for evaluation of spirometry function tests in South Asia, and amongst south asians living in other countries
(European Respiratory Society, 2022) Leong, W.Y.; Gupta, A.; Hasan, M.; Mahmood, S.; Siddiqui, S.; Ahmed, S.; Goon, I.Y.; Loh, M.; Mina, T.H.; Lam, B.; Yew, Y.W.; Ngeow, J.; Lee, J.; Lee, E.S.; Riboli, E.; Elliott, P.; Tan, G.P.; Chotirmall, S.H.; Wickremasinghe, A.R.; Kooner, J.S.; Khawaja, K.I.; Katulanda, P.; Mridha, M.K.; Jha, S.; Ranjit, M.A.; Pradeepa, G.; Kasturiratne, A.; Chambers, J.C.
Background: There is little data to accurate interpretation of spirometry data in South Asia, a major global region with high reported burden for chronic respiratory disease. Method: We measured lung function in 7,453 healthy men and women aged over 18 years, from Bangladesh, North India, South India, Pakistan and Sri Lanka, as part of the South Asia Biobank study. We first assessed the accuracy of existing equations for predicting normal forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), and FEV1/FVC ratio. We then used our data to derive (N=5589) and internally validate (N=1864) new prediction equations amongst South Asians, with further external validation amongst 339 healthy South Asians living in Singapore. Results: GLI2012 and NHANESIII consistently overestimated expiratory volumes (best fit GLI-African American, mean [sd] z-score (n=7453): FEV1 -0.94 [1.05]; FVC -0.91 [1.10]). Age, height and weight were strong predictors of lung function in our participants (p<0.001), and sex specific reference equations using these three variables were highly accurate in both internal validation (z-scores: FEV1 0.03 [0.99]; FVC 0.04 [0.97]; FEV1/FVC -0.03 [0.99]) and external validation (z-scores: FEV1 0.31 [0.99]; FVC 0.24 [0.97]; FEV1/FVC 0.16 [0.91]). Further adjustment for study regions improves the model fit, with highest accuracy for estimation of region specific lung function in South Asia. Conclusion: We present improved equations for predicting lung function in South Asians. These offer the opportunity to enhance diagnosis and management of acute and chronic lung diseases in this major global population.
Smokeless and combustible tobacco use among 148,944 South Asian adults: a cross-sectional study of South Asia Biobank
(Springer, 2023) Xie, W.; Mridha, M.K.; Gupta, A.; Kusuma, D.; Butt, A.M.; Hasan, M.; Brage, S.; Loh, M.; Khawaja, K.I.; Pradeepa, R.; Jha, V.; Kasturiratne, A.; Katulanda, P.; Anjana, R.M.; Chambers, J.C.
INTRODUCTION Tobacco use, in both smoking and smokeless forms, is highly prevalent among South Asian adults. The aims of the study were twofold: (1) describe patterns of SLT and combustible tobacco product use in four South Asian countries stratified by country and sex, and (2) assess the relationships between SLT and smoking intensity, smoking quit attempts, and smoking cessation among South Asian men. METHODS Data were obtained from South Asia Biobank Study, collected between 2018 and 2022 from 148,944 men and women aged 18 years and above, living in Bangladesh, India, Pakistan, or Sri Lanka. Mixed effects multivariable logistic and linear regression were used to quantify the associations of SLT use with quit attempt, cessation, and intensity. RESULTS Among the four South Asian countries, Bangladesh has the highest rates of current smoking (39.9% for male, 0.4% for female) and current SLT use (24.7% for male and 23.4% for female). Among male adults, ever SLT use was associated with a higher odds of smoking cessation in Bangladesh (OR, 2.88; 95% CI, 2.65, 3.13), India (OR, 2.02; 95% CI, 1.63, 2.50), and Sri Lanka (OR, 1.36; 95% CI, 1.14, 1.62). Ever SLT use and current SLT use was associated with lower smoking intensity in all countries. CONCLUSIONS In this large population-based study of South Asian adults, rates of smoking and SLT use vary widely by country and gender. Men who use SLT products are more likely to abstain from smoking compared with those who do not.
