Abstract
Background: Cancer registries worldwide are vital to determine cancer burden, plan cancer control measures, and facilitate research. Population-based cancer registries are a priority for LMICs by the UICC; the National Cancer Registry Program (NCRP) of India oversees 28 such registries. A primary function of registries is to combine data for the same individual from multiple sources. For other disease cohorts where cancer is an outcome of interest, registries can potentially connect information by linking datasets together. Barriers to successful registration and linkages include systems in which cancer is not a notifiable disease, no universal unique individual identifier exists, and lack of trained personnel. This study utilizes technology and infrastructure to develop better linkages, surveillance, and outcomes. Aim: To assess the feasibility of linking large cohorts designed for cardio-metabolic disease research with cancer registries in New Delhi and Chennai; determine additional steps required for linkage accuracy and completeness; and develop detailed protocols for future applications. Methods: A pilot protocol for linkage between a large diabetes cohort and cancer registries in Delhi and Chennai was developed using MatchPro, a probabilistic record linkage program developed for cancer registries. Probabilistic software links datasets together in the presence of uncertainty (eg misspelled or abbreviated names) to identify record pairs with high probability of representing the same individual. For this study, algorithms were developed to address unique aspects of names and demographics in India. The software and algorithms focused on: detecting duplicates in cancer registries; and linking registries with external files from diabetes cohorts. In Delhi, 3 1-year datasets covering 3 years (2010, 2011, 2012) were linked with the diabetes cohort; in Chennai, the linkage included 3 5-year datasets covering 15 years (2000-04, '05-'09, '10-'14). The unique ID (Aadhaar) is not collected or linked systematically between different systems at this point in time. Results: Linkage attempts yielded potential matches ranked according to probabilistic scores; highest scores were reviewed to determine true matches. In Chennai, this process yielded: (2010-2014) 21% self-reported (SR) cases matching perfectly, 36% requiring follow-up, 13 nonreported (NR) cases found; 2005-2009: 33% SR cases matched perfectly, 1 NR case found; 2000-2004: 1 NR case. Also, 2 training workshops on data linkages and software were held. Conclusion: Linkages between cancer registries and other data sources are feasible in LMICs using probabilistic record linkage software augmented by manual matching. Future efforts to use existing epidemiologic resources (cohorts) and cancer research infrastructure (registries and clinical centers) can enhance research including understanding shared risk factors and pathophysiologic mechanisms e.g., between cancer and other NCD.

Abstract
AIMS To enhance the antimicrobial and antibiofilm activity of norfloxacin against the planktonic and biofilm mode of growth in ESKAPE pathogens using chemically modified norfloxacin salts. METHODS AND RESULTS Antimicrobial testing, synergy testing and time-kill curve analysis were performed to evaluate antibacterial effect of norfloxacin carboxylic acid salts against ESKAPE pathogens. In vivo efficacy to reduce bacterial bioburden was evaluated in zebrafish infection model. Crystal violet assay and live-dead staining were performed to discern antibiofilm effect. Membrane permeability, integrity and molecular docking studies were carried out to ascertain the mechanism of action. The carboxylic acid salts, relative to parent molecule norfloxacin, displayed two- to fourfold reduction in minimum inhibitory concentration against Staphylococcus aureus and Pseudomonas aeruginosa, in addition to displaying potent bacteriostatic effect against certain members of ESKAPE pathogens. In vivo treatments revealed that norfloxacin tartrate (SRIN2) reduced MRSA bioburden by greater than 1 log fold relative to parent molecule in the muscle tissue. In silico docking with gyrA of S. aureus showed increased affinity of SRIN2 towards DNA gyrase. The enhanced antibacterial effect of norfloxacin salts could be partially accounted by altered membrane permeability in S. aureus and perturbed membrane integrity in P. aeruginosa. Antibiofilm studies revealed that SRIN2 (norfloxacin tartrate) and SRIN3 (norfloxacin benzoate) exerted potent antibiofilm effect particularly against Gram-negative ESKAPE pathogens. The impaired colonization of both S. aureus and P. aeruginosa due to improved norfloxacin salts was further supported by live-dead imaging. CONCLUSION Norfloxacin carboxylic acid salts can act as potential alternatives in terms of drug resensitization and reuse. SIGNIFICANCE AND IMPACT OF THE STUDY Our study shows that carboxylic acid salts of norfloxacin could be effectively employed to treat both planktonic- and biofilm-based infections caused by select members of ESKAPE pathogens.

Abstract
INTRODUCTION Depression and diabetes are highly prevalent worldwide and often co-exist, worsening outcomes for each condition. Barriers to diagnosis and treatment are exacerbated in low and middle-income countries with limited health infrastructure and access to mental health treatment. The INtegrating DEPrEssioN and Diabetes treatmENT (INDEPENDENT) study tests the sustained effectiveness and cost-effectiveness of a multi-component care model for individuals with poorly-controlled diabetes and depression in diabetes clinics in India. MATERIALS AND METHODS Adults with diabetes, depressive symptoms (Patient Health Questionnaire-9 score≥10), and ≥1 poorly-controlled cardiometabolic indicator (either HbA1c≥8.0%, SBP≥140mmHg, and/or LDL≥130mg/dl) were enrolled and randomized to the intervention or usual care. The intervention combined collaborative care, decision-support, and population health management. The primary outcome is the between-arm difference in the proportion of participants achieving combined depression response (≥50% reduction in Symptom Checklist score from baseline) AND one or more of: ≥0.5% reduction in HbA1c, ≥5mmHg reduction in SBP, or ≥10mg/dl reduction in LDL-c at 24months (12-month intervention; 12-month observational follow-up). Other outcomes include control of individual parameters, patient-centered measures (i.e. treatment satisfaction), and cost-effectiveness. RESULTS The study trained seven care coordinators. Participant recruitment is complete - 940 adults were screened, with 483 eligible, and 404 randomized (196 to intervention; 208 to usual care). Randomization was balanced across clinic sites. CONCLUSIONS The INDEPENDENT model aims to increase access to mental health care and improve depression and cardiometabolic disease outcomes among complex patients with diabetes by leveraging the care provided in diabetes clinics in India (clinicaltrials.gov number: NCT02022111).

Abstract
AIM To assess the lipid profiles in childhood and youth onset type 2 diabetes (T2DM) and study their association with microvascular complications. METHODS Clinical details of individuals with childhood and youth onset T2DM, age at diagnosis between 10 and 25 yrs (n=1340) were retrieved from electronic medical records. Lipid abnormalities were classified based on the NCEP (ATP III) guidelines and management of dyslipidemia in children and adolescents with diabetes. Retinopathy was assessed by retinal photography; nephropathy, if albumin excretion was ≥300 mg/g of creatinine or if the 24 hour protein excretion was >500 mg and neuropathy by elevated vibration perception threshold (≥20 V) on biothesiometry. RESULTS Out of 1,340 individuals with childhood and youth with T2DM, 53.3% of them were male. The mean age and duration of diabetes were 28.4 ± 10.4 and 7.4 ± 9.5 years respectively. Overall, the prevalence of dyslipidemia was 82.1%. Prevalence of hypercholesterolemia, hypertriglyceridemia, low HDL-C and high LDL-C were 40.7%, 52.8%, 59.1 % and 64.5% respectively. In logistic regression, both in unadjusted and adjusted model, hypercholesterolemia, and hypertriglyceridemia were associated with diabetic retinopathy [OR:1.8, CI:1.4-2.4, p<0.001 and 1.7, 1.3-2.2, p<0.001] and nephropathy [OR:1.7, CI:1.1-2.5, p=0.015 and 1.8, 1.2-2.8, p=0.007]. Additionally, hypercholesterolemia was associated with neuropathy, even after adjusting for age at diagnosis of diabetes and glycated hemoglobin [OR1.6, 1.0-2.5, p=0.041]. CONCLUSIONS Lipid abnormalities are common and associated with microvascular complications among these T2DM individuals. This underscores the need for effective control of lipids among childhood and youth onset T2DM.

Abstract
AIMS To investigate the prevalence of Campylobacter spp. and C. jejuni in dog faecal material collected from dog walkways in the city of Palmerston North, New Zealand, and to characterise the C. jejuni isolates by multilocus sequence typing (MLST) and porA and flaA antigen gene typing. METHODS A total of 355 fresh samples of dogs faeces were collected from bins provided for the disposal of dog faeces in 10 walkways in Palmerston North, New Zealand, between August 2008-July 2009. Presumptive Campylobacter colonies, cultured on modified charcoal cefoperazone deoxycholate plates, were screened for genus Campylobacter and C. jejuni by PCR. The C. jejuni isolates were subsequently characterised by MLST and porA and flaA typing, and C. jejuni sequence types (ST) were assigned. RESULTS Of the 355 samples collected, 72 (20 (95% CI=16-25)%) were positive for Campylobacter spp. and 22 (6 (95% CI=4-9)%) were positive for C. jejuni. Of the 22 C. jejuni isolates, 19 were fully typed by MLST. Ten isolates were assigned to the clonal complex ST-45 and three to ST-52. The allelic combinations of ST-45/flaA 21/porA 44 (n=3), ST-45/flaA 22/porA 53 (n=3) and ST-52/ flaA 57/porA 905 (n=3) were most frequent. CONCLUSIONS The successful isolation of C. jejuni from canine faecal samples collected from faecal bins provides evidence that Campylobacter spp. may survive outside the host for at least several hours despite requiring fastidious growth conditions in culture. The results show that dogs carry C. jejuni genotypes (ST-45, ST-50, ST-52 and ST-696) that have been reported in human clinical cases. CLINICAL RELEVANCE Although these results do not provide any evidence either for the direction of infection or for dogs being a potential risk factor for human campylobacteriosis, dog owners are advised to practice good hygiene with respect to their pets to reduce potential exposure to infection.

Abstract
OBJECTIVES This study examines in a cross-sectional study 'the tobacco control environment' including tobacco policy implementation and its association with quit ratio. SETTING 545 communities from 17 high-income, upper-middle, low-middle and low-income countries (HIC, UMIC, LMIC, LIC) involved in the Environmental Profile of a Community's Health (EPOCH) study from 2009 to 2014. PARTICIPANTS Community audits and surveys of adults (35-70 years, n=12 953). PRIMARY AND SECONDARY OUTCOME MEASURES Summary scores of tobacco policy implementation (cost and availability of cigarettes, tobacco advertising, antismoking signage), social unacceptability and knowledge were associated with quit ratios (former vs ever smokers) using multilevel logistic regression models. RESULTS Average tobacco control policy score was greater in communities from HIC. Overall 56.1% (306/545) of communities had >2 outlets selling cigarettes and in 28.6% (154/539) there was access to cheap cigarettes (<5cents/cigarette) (3.2% (3/93) in HIC, 0% UMIC, 52.6% (90/171) LMIC and 40.4% (61/151) in LIC). Effective bans (no tobacco advertisements) were in 63.0% (341/541) of communities (81.7% HIC, 52.8% UMIC, 65.1% LMIC and 57.6% LIC). In 70.4% (379/538) of communities, >80% of participants disapproved youth smoking (95.7% HIC, 57.6% UMIC, 76.3% LMIC and 58.9% LIC). The average knowledge score was >80% in 48.4% of communities (94.6% HIC, 53.6% UMIC, 31.8% LMIC and 35.1% LIC). Summary scores of policy implementation, social unacceptability and knowledge were positively and significantly associated with quit ratio and the associations varied by gender, for example, communities in the highest quintile of the combined scores had 5.0 times the quit ratio in men (Odds ratio (OR) 5·0, 95% CI 3.4 to 7.4) and 4.1 times the quit ratio in women (OR 4.1, 95% CI 2.4 to 7.1). CONCLUSIONS This study suggests that more focus is needed on ensuring the tobacco control policy is actually implemented, particularly in LMICs. The gender-related differences in associations of policy, social unacceptability and knowledge suggest that different strategies to promoting quitting may need to be implemented in men compared to women.

Abstract
Background Single nucleotide polymorphisms (SNPs) in lipoprotein lipase gene (LPL) have been shown to influence metabolism related to lipid phenotypes. Dietary factors have been shown to modify the association between LPL SNPs and lipids; however, to date, there are no studies in South Asians. Hence, we tested for the association of four common LPL SNPs with plasma lipids and examined the interactions between the SNPs and dietary factors on lipids in 1,845 Asian Indians. Methods The analysis was performed in 788 Type 2 diabetes cases and 1,057 controls randomly chosen from the cross-sectional Chennai Urban Rural Epidemiological Study. Serum triacylglycerol (TAG), serum total cholesterol, and high-density lipoprotein cholesterol (HDL-C) were measured using a Hitachi-912 autoanalyzer (Roche Diagnostics GmbH, Mannheim, Germany). Dietary intake was assessed using a semi-quantitative food frequency questionnaire. The SNPs (rs1121923, rs328, rs4922115 and rs285) were genotyped by polymerase chain reaction followed by restriction enzyme digestion and 20% of samples were sequenced to validate the genotypes obtained. Statistical Package for Social Sciences for Windows version 22.0 (SPSS, Chicago, IL) was used for statistical analysis. Results After correction for multiple testing and adjusting for potential confounders, SNPs rs328 and rs285 showed association with HDL-C (P = 0.0004) and serum TAG (P = 1×10−5), respectively. The interaction between SNP rs1121923 and fat intake (energy %) on HDL-C (P = 0.003) was also significant, where, among those who consumed a high fat diet (28.4 ± 2.5%), the T allele carriers (TT + XT) had significantly higher HDL-C concentrations (P = 0.0002) and 30% reduced risk of low HDL-C levels compared to the CC homozygotes. None of the interactions on other lipid traits were statistically significant. Conclusion Our findings suggest that individuals carrying T allele of the SNP rs1121923 have increased HDL-C levels when consuming a high fat diet compared to CC homozygotes. Our finding warrants confirmation in prospective studies and randomized controlled trials.

Abstract
BACKGROUND In the context of rising obesity in South Asia, it is unclear whether the "South Asian phenotype"(described as high glucose, low high-density lipoprotein cholesterol, and high triglycerides at normal ranges of body weight) continues to be disproportionately exhibited by contemporary South Asians relative to other race/ethnic groups. OBJECTIVES We assessed the distinctiveness of the South Asian cardiometabolic profile by comparing the prevalence of combined high glucose, high triglycerides, and low high-density lipoprotein cholesterol (combined dysglycemia and dyslipidemia) in resident South Asians with 4 race/ethnic groups in the United States (Asians, black persons, Hispanics, and white persons) overall and by body mass index (BMI) category. METHODS South Asian data were from the 2010 to 2011 Center for Cardiometabolic Risk Reduction in South Asia Study, representative of Chennai and New Delhi, India and Karachi, Pakistan. U.S. data were from the 2011 to 2012 National Health and Nutrition Examination Survey, representative of the U.S. POPULATION Combined dysglycemia and dyslipidemia was defined as fasting blood glucose ≥126 mg/dl and triglyceride/high-density lipoprotein cholesterol ratio >4. Logistic regression was used to estimate the relative odds and 95% confidence intervals of combined dysglycemia and dyslipidemia associated with each race/ethnic group (referent, U.S. white persons). Models were estimated among adults aged 20 to 79 years by sex and BMI category and accounted for age, education, and tobacco use. Data from 8,448 resident South Asians, 274 U.S. Asians, 404 U.S. black persons, 308 U.S. Hispanics, and 703 U.S. white persons without previously known diabetes were analyzed. RESULTS In the normal body weight range of BMI 18.5 to 24.9 kg/m(2), the prevalence of combined dysglycemia and dyslipidemia among men and women, respectively, was 33% and 11% in resident South Asians, 15% and 1% in U.S. Asians, 5% and 2% in U.S. black persons, 11% and 2% in U.S. Hispanics, and 8% and 2% in U.S. white persons. Compared with U.S. whites persons, South Asians were more likely to present with combined dysglycemia and dyslipidemia at all categories of BMI for men and at BMI 18.5 to 29.9 for women in adjusted models. The most pronounced difference between South Asians and U.S. white persons was observed at normal weight (adjusted odds ratio: 4.98; 95% confidence interval: 2.46 to 10.07 for men) (adjusted odds ratio: 9.09; 95% confidence interval: 2.48 to 33.29 for women). CONCLUSIONS Between 8% and 15% of U.S. men and 1% and 2% of U.S. women of diverse race/ethnic backgrounds exhibited dysglycemia and dyslipidemia at levels of body weight considered "healthy," consistent with the cardiometabolic profile described as the "South Asian Phenotype." Urban South Asians, however, were 5 to 9 times more likely to exhibit dysglycemia and dyslipidemia in the "healthy" BMI range compared with any other U.S. race/ethnic group.

Abstract
Non-communicable diseases (NCDs; including coronary heart disease and type 2 diabetes) are rapidly increasing in India causing nearly 5.8 million deaths per year. Primary reasons for rise in NCDs in India are nutrition and lifestyle transitions. Further, presence of higher body fat, abdominal fat, liver and pancreatic fat and lower lean mass than whites, contribute to heightened metabolic and cardiovascular risk in Asian Indians. Importantly, conversion from pre-diabetes to diabetes occurs more rapidly, and reversion to normal glucose regulation with appropriate lifestyle measures is more difficult in Asian Indians than white population. Huge number of patients with diabetes and with complications increase morbidity, mortality and pose substantial economic burden. It is difficult, though not impossible, to decrease pace of rapidly expanding juggernaut of NCDs in India. Only concerted efforts from multiple stakeholders, consistently sincere efforts and intensely focused attention from health officialdom and clear political will may help counter this increasingly difficult challenge. Finally, all prevention and management approaches should be cost-effective, pragmatic, and focused on children and underprivileged populations.

Abstract
In the context of high human consumption of fructose diets, there is an imperative need to understand how dietary fructose intake influence cellular and molecular mechanisms and thereby affect β-cell dysfunction and insulin resistance. While evidence exists for a relationship between high-fat-induced insulin resistance and metabolic disorders, there is lack of studies in relation to high-fructose diet. Therefore, we attempted to study the effect of different diets viz., high-fat diet (HFD), high-fructose diet (HFS), and a combination (HFS + HFD) diet on glucose homeostasis and insulin sensitivity in male Wistar rats compared to control animals fed with normal pellet diet. Investigations include oral glucose tolerance test, insulin tolerance test, histopathology by H&E and Masson's trichrome staining, mRNA expression by real-time PCR, protein expression by Western blot, and caspase-3 activity by colorimetry. Rats subjected to high-fat/fructose diets became glucose intolerant, insulin-resistant, and dyslipidemic. Compared to control animals, rats subjected to different combination of fat/fructose diets showed increased mRNA and protein expression of a battery of ER stress markers both in pancreas and liver. Transcription factors of β-cell function (INSIG1, SREBP1c and PDX1) as well as hepatic gluconeogenesis (FOXO1 and PEPCK) were adversely affected in diet-induced insulin-resistant rats. The convergence of chronic ER stress towards apoptosis in pancreas/liver was also indicated by increased levels of CHOP mRNA & increased activity of both JNK and Caspase-3 in rats subjected to high-fat/fructose diets. Our study exposes the experimental support in that high-fructose diet is equally detrimental in causing metabolic disorders.

Abstract
Gestational diabetes mellitus (GDM) is one of the most common metabolic complications of pregnancy. Ever since the first systematic evaluation of the oral glucose tolerance test by O'Sullivan and colleagues was carried out in 1964, there has been controversy with respect to the optimal screening and diagnostic criteria to detect GDM. The recently proposed International Association of Diabetes and Pregnancy Study Groups (IADPSG) criteria for GDM has found fairly widespread acceptance, but it is still debated by several societies. This review intends to provide an overview of the evolution of the screening and diagnostic criteria for GDM. Debatable issues regarding optimal screening strategies, especially in the low resource settings of low and middle income countries are highlighted. The recent Women in India with GDM Strategy (WINGS) project carried out in Chennai, India tried to develop a Model of Care for GDM suitable for resource constrained settings. The findings related to screening and diagnosis of GDM based on WINGS are also highlighted in this review. Based on the WINGS experience we believe that despite the constraints in low and middle income countries at the present time, the IADPSG criteria appears to be the best. This will also help to bring out a uniform criteria for screening and diagnosis of GDM worldwide.

Abstract
We compared the hyperglycemia prevalence in Asian Indians to other ethnic groups. The prevalence of diabetes was higher in Indians compared to other ethnic groups. The prevalence of prediabetes was lower in Indians compared to other ethnic groups. These differences may be driven by impaired β-cell function.
Aims It is unclear how the prevalence of diabetes in Asian Indians in urban India compares to that of race/ethnic groups in the US that may have different underlying susceptibilities. Therefore, we examined ethnic variations in the prevalence of type 2 diabetes, iIFG, iIGT, IFG + IGT, and the associated risk factors in Asian Indians in Chennai, India, and Whites, Blacks, and Hispanics in the United States. Methods Cross-sectional analyses, using representative samples of 4867 Asian Indians aged 20–74 years from Chennai, India, in the Centre for Cardiometabolic Risk Reduction in South-Asia study (CARRS) (2010–2011) and 6512 US Whites, Blacks, and Hispanics aged 20–74 years from the National Health and Nutrition Examination Survey (NHANES) (2007–2012). Results The age-adjusted prevalence of type 2 diabetes was highest in Asian Indians (men: 28.4, 95% CI: 25.9, 31.0; women: 30.6, 95% CI, 27.5, 33.9) and lowest in Caucasians (men: 12.2, 95% CI, 10.3, 14.4, women: 9.5, 95% CI, 7.9, 11.5). Asian Indians had the lowest prediabetes prevalence (men: 19.0, 95% CI, 17.2, 20.8; women: 27.2, 95% CI, 22.8, 32.1) and Caucasians had the highest (men; 46.5, 95% CI, 43.5, 49.6, women: 34.4, 95% CI, 31.7, 37.3). However, there were differences in prediabetes prevalence by gender and prediabetes state. The inclusion of HOMA-β in standardized polytomous logistic regression models resulted in a greater odds of diabetes in Blacks and Hispanics compared to Asian Indians. Conclusions The high prevalence of diabetes in Asian Indians may be due to innate susceptibilities for β-cell dysfunction in this high risk population.

Abstract
Maturity-onset diabetes of the young (MODY) is a genetically heterogeneous monogenic form of diabetes characterized by onset of diabetes below 25 years of age, autosomal dominant mode of inheritance and primary defect in insulin secretion. Mutations in the gene (HNF1A) encoding transcription factor hepatocyte nuclear factor 1A (HNF-1A) results in one of the most common forms of MODY (MODY3). HNF-1A is mainly enriched in pancreatic β-cells and hepatocytes and important for organ development and normal pancreatic function. We here report on the functional interrogation of eight missense HNF1A mutations associated with MODY3 in South Indian subjects, and the contributing effect of common variant (S487N) within HNF1A. Of the eight mutations, three mutations (p.R171G, p.G245R and p.R263H), in particular, affected HNF-1A function in transfected HeLa cells by reducing both transcriptional activity and nuclear localization, possibly due to disruption of the integrity of the three dimensional structure. The common variant p.S487N contributed further to the loss-of-function of p.R271Q (p.R271Q+p.S487N double mutant), in vitro, on both activity and localization. Our data on the first functional study of HNF1A mutations in South India subjects confers that the defect of the HNF-1A mutant proteins are responsible for MODY3 diabetes in these patients.

Abstract
PURPOSE OF THE STUDY To look at the association of central and peripheral skinfold thickness with parental history of diabetes in subjects without diabetes. METHODS Subjects with no parental history of diabetes (n=1132), subjects with one parent with diabetes (n=271) and subjects with both parents with diabetes (n=51) were recruited from the Chennai Urban Rural Epidemiological Study (CURES) conducted between 2001 and 2003. Biceps, triceps, medial calf, mid-thigh, chest, abdomen, mid-axillary, suprailiac and subscapsular sites were measured with Lange skinfold callipers. RESULTS Trunk fat measurements, such as chest (p=0.020), mid-axillary (p=0.005), suprailiac (p=0.014), subscapsular (p<0.001) and abdomen (p=0.010) skinfolds, were highest in subjects with both parents with diabetes followed by those with one parent with diabetes, and lowest in those with no parental history of diabetes. However, the peripheral fat measurements, ie, biceps, triceps, medial calf and mid-thigh, were not significantly different between the study groups. Total truncal and peripheral fat skinfold thicknesses showed a significant positive association with other indices of obesity such as body mass index (BMI) and waist circumference in relation to trunk fat (BMI: r=0.748, p<0.001; waist: r=0.776, p<0.001) and peripheral fat (BMI: r=0.681, p<0.001; waist: r=0.569, p<0.001). CONCLUSIONS A significant association was observed between truncal and peripheral fat, assessed by skinfold thickness, and parental history of diabetes among subjects without diabetes in this urban South Indian population.

Abstract
OBJECTIVE To examine and compare tobacco marketing in 16 countries while the Framework Convention on Tobacco Control requires parties to implement a comprehensive ban on such marketing. METHODS Between 2009 and 2012, a kilometre-long walk was completed by trained investigators in 462 communities across 16 countries to collect data on tobacco marketing. We interviewed community members about their exposure to traditional and non-traditional marketing in the previous six months. To examine differences in marketing between urban and rural communities and between high-, middle- and low-income countries, we used multilevel regression models controlling for potential confounders. FINDINGS Compared with high-income countries, the number of tobacco advertisements observed was 81 times higher in low-income countries (incidence rate ratio, IRR: 80.98; 95% confidence interval, CI: 4.15-1578.42) and the number of tobacco outlets was 2.5 times higher in both low- and lower-middle-income countries (IRR: 2.58; 95% CI: 1.17-5.67 and IRR: 2.52; CI: 1.23-5.17, respectively). Of the 11,842 interviewees, 1184 (10%) reported seeing at least five types of tobacco marketing. Self-reported exposure to at least one type of traditional marketing was 10 times higher in low-income countries than in high-income countries (odds ratio, OR: 9.77; 95% CI: 1.24-76.77). For almost all measures, marketing exposure was significantly lower in the rural communities than in the urban communities. CONCLUSION Despite global legislation to limit tobacco marketing, it appears ubiquitous. The frequency and type of tobacco marketing varies on the national level by income group and by community type, appearing to be greatest in low-income countries and urban communities.

Abstract
OBJECTIVE This study examines whether a new, scored and breakable once daily gliclazide tablet formulation, gliclazide XR 60 mg, that enables a simple 2-steps titration, can improve glycemic control rates in the community. METHODS In a prospective multicenter study of 4 months duration, organised in the primary care setting of urban India, type 2 diabetes patients, uncontrolled with diet alone or metformin monotherapy, received 1 (60 mg), 1½ (90 mg), or 2 (120 mg) tablets of gliclazide XR 60 mg to achieve a target fasting plasma glucose of 126 mg/dl, or HbA1c of 7%. The primary outcome was the frequency of patients achieving glycemic control. RESULTS Two hundred eleven investigators recruited 679 patients distributed throughout India. On intention to treat analysis, the number (%, 95% confidence interval, CI) of patients achieving glycemic control was, 526 (81.9, 78.8 to 84.6); with gliclazide XR 60 mg 1 tablet, 285 (42.0, 38.3 to 45.7); 1½ tablets, 143 (21.1, 18.2 to 24.3); and 2 tablets, 98 (14.4, 12.0 to 17.3). Hypoglycaemic episodes were reported by 27 (4.0, 2.8 to 5.7) patients. Mean (95% CI) FPG decreased by 78.3 (73.9 to 82.7, P < 0.01) mg/dl; with 1 tablet gliclazide XR 60 mg, by 66.0 (61.1 to 70.9, P < 0.01) mg/dl; 1-½ tablets, by 80.1 (71.2 to 88.5, P < 0.01) mg/dl; and 2 tablets, by 106.5 (93.4 to 119.5, P< 0.01) mg/dl. HbA1c decreased by 1.5 (1.3 to 1.5, P < 0.01). CONCLUSIONS In primary care, once daily, breakable extended release gliclazide XR 60 mg, with a simple two step titration to administer maximum recommended dosage is effective in achieving short term glycemic control with a low frequency of hypoglycaemia, in monotherapy or in combination with metformin.

Abstract
AIM To describe recruitment challenges in a randomized controlled translational trial (RCTT) of diabetes prevention in India. METHODS The Diabetes Community Lifestyle Improvement Program (D-CLIP) is a RCTT, comparing standard of care to a step-wise model of diabetes prevention. Overweight adults with prediabetes were identified through a two-step screening process (1) field-based screening: minimal testing with a random capillary glucose measurement and (2) clinic-based screening including an Oral Glucose Tolerance Test (OGTT). RESULTS Individuals from the community (n=19377) were screened at residential locations, offices, educational institutions, places of worship, parks and beaches. Of these, 3535 (18.2%) 'high-risk' participants based on capillary glucose values were eligible for step 2 screening with OGTT. However, only 21.5% participated. An additional 521 participants directly entered step 2 via direct referrals from our clinical/research databases, study participant referrals and targeted advertisements. Of the 1285 individuals who underwent an OGTT, 710 (55.3%) were eligible for randomization, and 602 (84.8%) were randomized into the trial. The ratio of participants entering from step 1 to step 2 was 25:1 (3.9%) and from step 2 to randomization 2:1 (47%). Average staff time for recruitment was 350 h per week for an 11-person team. CONCLUSIONS Nearly 55 people needed to be screened with a questionnaire plus capillary glucose test to randomize one participant with prediabetes. Using a 2-step strategy requires additional staff time, but considerably reduces the need for OGTT's, thereby minimizing participant burden and study costs.

Abstract
AIM To conduct a systematic review on the prevalence, risk factors, treatments and outcomes of Coronary Artery Disease (CAD) in Indians. METHODS AND RESULTS We conducted a systematic review of studies in Indians with CAD from Jan 1969 to Oct 2012. Initial search yielded 3885 studies and after review 288 observational studies were included. The prevalence of CAD in urban areas was 2.5%-12.6% and in rural areas, 1.4%-4.6%. The prevalence of risk factors was: smoking (8.9-40.5%), hypertension (13.1-36.9%) and diabetes mellitus (0.2-24.0%). The median time to reach hospital after an MI was 360 min. In hospital rates of drug use were: antiplatelets 68%-97.9%, beta blockers 47.3%-65.8% and ACEIs 27.8-56.8%. CONCLUSIONS In this first systematic review of CAD in India, prevalence of risk factors is high, treatments delayed and use of evidence based treatments variable.

In the US, the new subspecialty of Clinical Informatics focuses on systems-level improvements in care delivery through the use of health information technology (HIT), data analytics, clinical decision support, data visualization and related tools. Clinical informatics is one of the first subspecialties in medicine open to physicians trained in any primary specialty. Clinical Informatics benefits patients and payers such as Medicare and Medicaid through its potential to reduce errors, increase safety, reduce costs, and improve care coordination and efficiency. Even though Clinical Informatics benefits patients and payers, because GME funding from the Centers for Medicare and Medicaid Services (CMS) has not grown at the same rate as training programs, the majority of the cost of training new Clinical Informaticians is currently paid by academic health science centers, which is unsustainable. To maintain the value of HIT investments by the government and health care organizations, we must train sufficient leaders in Clinical Informatics. In the best interest of patients, payers, and the US society, it is therefore critical to find viable financial models for Clinical Informatics fellowship programs. To support the development of adequate training programs in Clinical Informatics, we request that the Centers for Medicare and Medicaid Services (CMS) issue clarifying guidance that would allow accredited ACGME institutions to bill for clinical services delivered by fellows at the fellowship program site within their primary specialty.

Abstract
AIMS To assess geographic differences in the association between BMI, blood pressure and lipid levels with impaired glucose regulation among young adults from various geographical regions. METHODS This was a cross-sectional study including data from 6987 participants aged ≤ 30 years from India, Singapore, Australia, Greenland, Kenya and Tanzania. Impaired glucose regulation was determined by the 75-g oral glucose tolerance test. For each geographical region, BMI, blood pressure and lipids were examined and compared between participants with normal glucose tolerance and those with impaired glucose regulation. Multiple logistic regression models were used to assess the association between risk factors and impaired glucose regulation. RESULTS Indian and East African people had a higher prevalence of impaired glucose regulation compared with participants from other regions, despite their lower BMI. Compared with the other regions, blood pressure was lower among Indian and Singaporean people but higher in those from Greenland. Greenlanders had the highest, while Indian and East-African people, had the lowest level of HDL cholesterol. BMI was positively associated with impaired glucose regulation in all regions, and there were no statistically significant geographic differences. In the Indian, Singaporean and Australian participants, there was a positive association between blood pressure and impaired glucose regulation. Triglycerides were positively associated with and HDL cholesterol had no association with impaired glucose regulation in all geographical regions. CONCLUSIONS Higher BMI and triglyceride levels were positively associated with prevalent impaired glucose regulation in all geographical regions. There were geographic differences in the association between impaired glucose regulation and blood pressure and lipids, probably reflecting environmental and genetic factors.

Abstract
BACKGROUND In 2007, we initiated a health information management (HIM) track of our biomedical informatics graduate program, and subsequent ongoing program assessment revealed a confluence of topics and courses within HIM and clinical informatics (CI) tracks. We completed a thorough comparative analysis of competencies derived from AMIA, AHIMA, and CAHIIM. Coupled with the need to streamline course offerings, the process, described in this paper allowed new opportunities for faculty collaboration, resulted in the creation of a model assessment for best practice in courses, and led to new avenues of growth within the program. OBJECTIVE The objective of the case study is to provide others in the informatics educational community with a model for analysis of curriculum in order to improve quality of student learning. METHODS We describe a case study where an academic informatics program realigned its course offerings to better reflect the HIM of today, and prepare for challenges of the future. Visionary leadership, intra-departmental self-analysis and alignment of the curriculum through defined mapping process reduced overlap within the CI and HIM tracks. Teaching within courses was optimized through the work of core faculty collaboration. RESULTS The analysis of curriculum resulted in reduction of overlap within course curriculum. This allowed for additional and new course content to be added to existing courses. CONCLUSIONS Leadership fostered an environment where top-down as well as bottom-up collaborative assessment activities resulted in a model to consolidate learning and reduce unnecessary duplication within courses. A focus on curriculum integration, emphasis on course alignment and strategic consolidation of course content raised the quality of informatics education provided to students. Faculty synergy was an essential component of this redesign process. Continuous quality improvement strategy included an ongoing alignment of curriculum and competencies through a comparative analysis approach. Through these efforts, new innovation was possible.

Abstract
AIMS This paper attempts to describe the patterns of exercise and the perceived benefits and barriers to exercise in an urban south Indian population. METHODS Study participants were recruited from the baseline survey of the D-CLIP (Diabetes Community Lifestyle Improvement Program). Frequency, duration, type and location of exercise were assessed using a questionnaire, while a Likert type scale was used to assess perceived benefits of and barriers to exercise. Quality of life was measured using the EQ-5D. RESULTS Out of 1281 participants (63.7% males), 24.1% reported doing ≥150min of exercise/week ("exercisers") compared to 75.9% "non-exercisers". Exercisers were significantly older (47 vs. 43 years), better educated (68.8% vs. 60%), had a higher monthly income (41% vs. 29.2%), consumed more fruits (38.2% vs. 25.6%) and vegetables (84.1% vs. 77.7%) and had better perceived state of health (81.1% vs. 76.8%), compared to non-exercisers. Exercisers had significantly lower HOMA-IR, higher Matsuda index and lower prevalence of low HDL cholesterol compared to non-exercisers. However, there were no significant differences in cardio-metabolic risk factors like diabetes, hypertension and obesity between the two groups. Walking was the most common type of exercise. Both exercisers and non-exercisers perceived the benefits of exercising, but barriers weighed more heavily on exercise behaviour. CONCLUSIONS Urgent steps are needed to improve overall exercise levels in India by addressing barriers and improving the quality of exercise performed so as to enhance overall metabolic health.

Abstract
The objective of this research was to test an in vitro motility model by investigating whether a probiotic that reduces diarrhea in humans would reduce motility in the rat colon in vitro. The probiotic Escherichia coli Nissle 1917 (EcN) the active ingredient in Mutaflor® was used as an example probiotic because it is effective for treating infectious diarrheal diseases. The effect of EcN on motility was compared in two colonic preparations. In distal colon segments EcN extract decreased the tension of spontaneous contractions by 74% and frequency by 46% compared with pre-treatment controls. In the whole large intestine the number of synchronized spontaneous propagating contractions decreased by 86% when EcN extract was applied externally and 69% when applied via the lumen compared with pre-treatment. From the inhibition produced by EcN extract in the distal colon segment a myogenic action was inferred and in the whole large intestine neural involvement was implicated. Both are consistent with its anti-diarrheal effect in humans.

Abstract
OBJECTIVES To assess the association of serum adiponectin and microvascular complications of diabetes in an urban south Indian type 2 diabetic population. DESIGN AND METHODS Diabetic subjects [n=487] were included from Chennai Urban Rural Epidemiology Study (CURES). Four-field stereo retinal color photography was done and diabetic retinopathy (DR) was classified as non-proliferative DR (NPDR) or proliferative DR (PDR) according to the Early Treatment Diabetic Retinopathy Study grading system. Sight threatening DR (STDR) was defined as the presence of NPDR with diabetic macular edema, and/or PDR. Neuropathy was diagnosed if vibratory perception threshold of the great toe using biothesiometry exceeded ≥20V. Nephropathy was diagnosed if urinary albumin excretion (UAE) was ≥30μg/mg creatinine. Serum total adiponectin levels were measured by radioimmunoassay. RESULTS Subjects with any microvascular complications had significantly higher levels of adiponectin levels compared to those without the complications (geometric mean: 6.1 vs. 5.3μg/mL, p=0.004). The adiponectin level was significantly higher in subjects with DR (6.8 vs. 5.5μg/mL, p=0.004) and neuropathy (5.6 vs. 6.5μg/mL, p=0.024) compared to those without. Adiponectin levels were not significantly different in subjects with and without nephropathy. Serum adiponectin levels increased with the severity of DR [No DR - 5.5μg/mL; NPDR without DME - 6.5μg/mL; STDR - 8.3μg/mL, p=0.001]. Regression analysis revealed adiponectin to be associated with microvascular disease (presence of neuropathy and/or retinopathy and/or nephropathy) (OR: 1.44, 95% CI: 1.01-2.06, p=0.049) even after adjusting for age, gender, BMI, HbA1c, diabetes of duration, serum cholesterol and triglycerides, hypertension and medication status. CONCLUSION In Asian Indians with type 2 diabetes, serum adiponectin levels are associated with microvascular complications and also with the severity of retinopathy.

Abstract
AIMS Clinical inertia, the tendency to maintain current treatment strategies despite results demanding escalation, is thought to substantially contribute to the disconnect between clinical aspirations for patients with diabetes and targets achieved. We wished to explore potential causes of clinical inertia among physicians and people with diabetes. METHODS A 20-min online survey of 652 adults with diabetes and 337 treating physicians in six countries explored opinions relating to clinical inertia from both perspectives, in order to correlate perceptions and expectations relating to diagnosis, treatment, diabetes complications and therapeutic escalation. RESULTS Physicians had low expectations for their patients, despite the belief that the importance of good glycaemic control through lifestyle and pharmacological interventions had been adequately conveyed. Conversely, people with diabetes had, at best, a rudimentary understanding of the risks of complications and the importance of good control; indeed, only a small proportion believed lifestyle changes were important and the majority did not intend to comply. CONCLUSIONS The principal findings of this survey suggest that impairments in communication are at the heart of clinical inertia. This manuscript lays out four key principles that we believe are achievable in all environments and can improve the lives of people with diabetes.

Abstract
BACKGROUND AND AIM COPD is a progressive and irreversible disease, thus assessing the impact of the disease on health-related quality of life (HRQOL) is important in the management of COPD. The aim of this study was to examine the relationship between HRQOL, lung function and dyspnea rating in patients with stable COPD. METHODS One hundred COPD patients (mean age = 64.76 +/- 11.43 years) were recruited for this cross-sectional study. Lung function test was measured using a FlowScreen portable spirometry. Dyspnea rating was measured using the baseline dyspnea index (BDI). HRQOL was assessed using the SF-36v2 which summarized two components; physical health component summary (PHCS) and mental health component summary (MHCS). THE RESULTS The mean value of lung function (Forced expiratory volume in 1 second, FEV1% predicted) was 58.19 +/- 30.24 and dyspnea rating was 6.85 +/- 2.68. The lung function was significantly correlated with MHCS (r=.294, p < 0.05) but not with the PHCS (p > 0.05). The dyspnea rating was significantly correlated with both PHCS (r=.730, p < 0.05) and MHCS (r = .324, p < 0.05). Regression analysis indicated that dyspnea rating emerged as the most significant predictor for PHCS and MHCS accounting for 54% and 12% of the variances respectively. CONCLUSIONS The findings show that dyspnea rating is an important factor in predicting HRQOL of patients with COPD. This indicates that dyspnea rating influences HRQOL to a greater extent than the physiological measurement of lung function. Therefore, focusing on such predictors at an early stage may provide meaningful benefits in the management of COPD.

Abstract
BACKGROUND Representative data on knowledge and awareness about diabetes is scarce in India and is extremely important to plan public health policies aimed at preventing and controlling diabetes. AIM The aim of the following study is to assess awareness and knowledge about diabetes in the general population, as well as in individuals with diabetes in four selected regions of India. MATERIALS AND METHODS The study subjects were drawn from a representative sample of four geographical regions of India, Chandigarh, Tamil Nadu, Jharkhand and Maharashtra representing North, South, East and West and covering a population of 213 million. A total of 16,607 individuals (5112 urban and 11,495 rural) aged ≥20 years were selected from 188 urban and 175 rural areas. Awareness of diabetes and knowledge of causative factors and complications of diabetes were assessed using an interviewer administered structured questionnaire in 14,274 individuals (response rate, 86.0%), which included 480 self-reported diabetic subjects. RESULTS Only 43.2% (6160/14,274) of the overall study population had heard about a condition called diabetes. Overall urban residents had higher awareness rates (58.4%) compared to rural residents (36.8%) (P < 0.001). About 46.7% of males and 39.6% of females reported that they knew about a condition called diabetes (P < 0.001). Of the general population, 41.5% (5726/13,794) knew about a condition called diabetes. Among them, 80.7% (4620/5726) knew that the prevalence of diabetes was increasing, whereas among diabetic subjects, it was 93.0% (448/480). Among the general and diabetic population, 56.3% and 63.4% respectively, were aware that diabetes could be prevented. Regarding complications, 51.5% of the general population and 72.7% diabetic population knew that diabetes could affect other organs. Based on a composite knowledge score to assess knowledge among the general population, Tamil Nadu had the highest (31.7) and Jharkhand the lowest score (16.3). However among self-reported diabetic subjects, Maharashtra had the highest (70.1) and Tamil Nadu, the lowest score (56.5). CONCLUSION Knowledge and awareness about diabetes in India, particularly in rural areas, is poor. This underscores the need for conducting large scale diabetes awareness and education programs.
