- BACKGROUND: India is home to the largest population of patients with tuberculosis and tobacco users in the world. Smokeless tobacco use exceeds smoking and is increasing. There is no study to date that reports smokeless tobacco use before and after the diagnosis and treatment of tuberculosis. We assessed smokeless tobacco use among former patients of tuberculosis in Karnataka, India.METHODS: We conducted a community-based, cross sectional study among 202 men, who had been diagnosed and treated for tuberculosis (mean age 48 years), selected by multistage, random sampling. Using a semi-structured interview schedule, retrospective smoking and smokeless tobacco use were captured at eight time-points before and after the diagnosis and treatment of tuberculosis.RESULTS: Most patients suspended tobacco use during treatment. A high 44% prevalence of smokeless tobacco use 6 months before diagnosis was reduced to just 8% during the intensive phase of treatment and climbed to 27% 6 months after treatment. The tobacco use relapse rate 6 months after completion of treatment was higher for smokeless tobacco use (52%, 95% CI 41%-62%) than for smoking (36%, 95% CI 26%-45%). We also found that many patients who were advised to quit smoking continued using smokeless tobacco after completion of treatment. Additionally, new smokeless tobacco use was documented. Of the 11 new exclusive smokeless tobacco users, 10 shifted from smoking to smokeless tobacco use as a form of harm reduction.CONCLUSION: Patients with tuberculosis are advised by their doctors, at the time of diagnosis, to quit smoking. Several patients shift from smoking to smokeless tobacco use, which needs to be addressed while providing tobacco cessation services.

- Blood pressure (BP) is a heritable determinant of risk for cardiovascular disease (CVD). To investigate genetic associations with systolic BP (SBP), diastolic BP (DBP), mean arterial pressure (MAP) and pulse pressure (PP), we genotyped 50 000 single-nucleotide polymorphisms (SNPs) that capture variation in 2100 candidate genes for cardiovascular phenotypes in 61 619 individuals of European ancestry from cohort studies in the USA and Europe. We identified novel associations between rs347591 and SBP (chromosome 3p25.3, in an intron of HRH1) and between rs2169137 and DBP (chromosome1q32.1 in an intron of MDM4) and between rs2014408 and SBP (chromosome 11p15 in an intron of SOX6), previously reported to be associated with MAP. We also confirmed 10 previously known loci associated with SBP, DBP, MAP or PP (ADRB1, ATP2B1, SH2B3/ATXN2, CSK, CYP17A1, FURIN, HFE, LSP1, MTHFR, SOX6) at array-wide significance (P 2.4 10(6)). We then replicated these associations in an independent set of 65 886 individuals of European ancestry. The findings from expression QTL (eQTL) analysis showed associations of SNPs in the MDM4 region with MDM4 expression. We did not find any evidence of association of the two novel SNPs in MDM4 and HRH1 with sequelae of high BP including coronary artery disease (CAD), left ventricular hypertrophy (LVH) or stroke. In summary, we identified two novel loci associated with BP and confirmed multiple previously reported associations. Our findings extend our understanding of genes involved in BP regulation, some of which may eventually provide new targets for therapeutic intervention.

- Blood pressure (BP) is a heritable risk factor for cardiovascular disease. To investigate genetic associations with systolic BP (SBP), diastolic BP (DBP), mean arterial pressure (MAP), and pulse pressure (PP), we genotyped ∼50,000 SNPs in up to 87,736 individuals of European ancestry and combined these in a meta-analysis. We replicated findings in an independent set of 68,368 individuals of European ancestry. Our analyses identified 11 previously undescribed associations in independent loci containing 31 genes including PDE1A, HLA-DQB1, CDK6, PRKAG2, VCL, H19, NUCB2, RELA, HOXC@ complex, FBN1, and NFAT5 at the Bonferroni-corrected array-wide significance threshold (p < 6 × 10(-7)) and confirmed 27 previously reported associations. Bioinformatic analysis of the 11 loci provided support for a putative role in hypertension of several genes, such as CDK6 and NUCB2. Analysis of potential pharmacological targets in databases of small molecules showed that ten of the genes are predicted to be a target for small molecules. In summary, we identified previously unknown loci associated with BP. Our findings extend our understanding of genes involved in BP regulation, which may provide new targets for therapeutic intervention or drug response stratification.
