Introduction: To curb the ever growing menace of tobacco and its ill effects, it is essential to prevent its usage. Dental professionals' contributions can be invaluable in this venture. Objectives: To assess Indian dental graduates' knowledge, attitude and practices towards tobacco cessation; perceived effectiveness in pursuing tobacco cessation activities; perception of factors that interfere in tobacco cessation as barriers; and willingness to participate in tobacco cessation. Further, to determine associations among the aforementioned variables. Methodology: All house surgeons in Manipal College of Dental Sciences, Manipal University, Mangalore were included in the study. A structured, pre-tested and self-administered questionnaire was employed to assess participants' knowledge, attitude, behavior, perceived effectiveness, perceived barriers and willingness to participate in tobacco cessation. Information regarding respondents' age, gender and residence was collected. Results: A total of 100 out of 103 respondents participated in the study. Mean knowledge, attitude, behavior, perceived effectiveness, perceived barrier scores were $17.6{\pm}2.53$ (73.2%), $72.1{\pm}6.59$ (90.2%), $28.3{\pm}5.12$ (67.4%), $13.3{\pm}5.36$ (53.16%) and $35.0{\pm}3.79$ (89.8%) respectively. Overall, 97% respondents were willing to participate in tobacco cessation activities. Correlation analysis revealed that knowledge was associated with attitude (r=0.36, p=0.00) and perceived barriers (r=0.34, p=0.00) and behavior was associated with perceived barriers (r=0.22, p=0.03). Conclusions: Respondents reported high knowledge and attitude scores, along with high perceived barriers scores and willingness to participate in tobacco cessation activities. Present study highlights the need for a more meaningful involvement of dental professionals in tobacco cessation and has policy implications for curriculum changes regarding the same.

Objectives: Medical students represent a primary target for tobacco cessation training. This study assessed the prevalence of medical students' tobacco use, attitudes, clinical skills, and tobacco-related curricula in two countries, the US and Italy, with known baseline disparities in hopes of identifying potential corrective interventions. Methods: From September to December 2013, medical students enrolled at the University of Bologna and at Brown University were recruited via email to answer survey questions assessing the prevalence of medical students' tobacco use, attitudes and clinical skills related to patients' smoking, and elements of medical school curricula related to tobacco use. Results: Of the 449 medical students enrolled at Brown and the 1426 enrolled at Bologna, 174 Brown students (38.7%) and 527 Bologna students (36.9%) participated in this study. Italian students were more likely to smoke (29.5% vs. 6.1%; p<0.001) and less likely to receive smoking cessation training (9.4% vs. 80.3%; p<0.001) than their American counterparts, even though the majority of students in both countries desired smoking cessation training (98.6% at Brown, 85.4% at Bologna; p<0.001). Additionally, negative beliefs regarding tobacco usage, the absence of formal training in smoking cessation counseling, and a negative interest in receiving specific training on smoking cessation were associated with a higher risk of not investigating a patient's smoking status during a routine history and not offering tobacco cessation treatment to patients. Conclusions: Medical curricula on tobacco-related health hazards and on smoking cessation should be mandatory in order to reduce smoking among medical students, physicians, and patients, thereby improving tobacco-related global health.
Investigation on the ability of nitrogen usage by N2-fixing Nostoc muscorum and cultured tobacco cells when they were associately cultured on nitrogen-free media was carried out. Also, effect of polyamines on the associated cultured condition was carried out. In addition, morphological changes of N. muscorum and cultured tobacco cells in associate culture were observed to detect the possibility of induction of nitrogen fixing ability on cultued plant cells. The activity of nitrogenase increased markedly when N. muscorum was grown exclusively on nitrogen-free media. When N. muscorum was cultured associately with cultured tobacco cells on nitrogen-free media containing polyamines, high activity was detected in 10-4 M spermine treated group. Investigation on the change of polyamine amounts showed two times increase in spermidine and eight times increase in spermine on a associate culture. These effects of associated culture were shown through morphological change such as dense loclization of N. muscorum around the cultured tobacco cells as well as inside the cells. These results indicate the viability of N. muscorum in cultured tobacco cells and possible induction of nitrogen fixation ability by symbiosis.
Background: Smokeless tobacco (SLT) has long been realized as an important component of the fight for global tobacco control. It still remains a major problem in countries like India, Bangladesh and Nepal. The objective of this study was to estimate the trends of SLT use in three countries of the SEARO WHO office. Materials and Methods: We used data from national surveys in three countries (Bangladesh, India and Nepal) to estimate trends in prevalence of current SLT use. All available nationally representative data sources were used. Estimates were weighted, age standardized and given along with 95% confidence intervals. Significance of linear trend in prevalence over time was tested using the Cochrane-Armitage test for trend. A p value of less than 0.05 was considered statistically significant. Results: We identified three surveys for Bangladesh, three for India and four for Nepal that met the selection criteria (such as Demographic and Health Surveys, WHO-STEPwise approach to Surveillance and Global Adult Tobacco Surveys). A significantly increasing trend was noticed in the prevalence of current SLT use among Bangladeshi men (20.2% to 23%, p=0.03). In India, a similar significantly increasing trend was seen among men (27.1% to 33.4%, p<0.001) and women (10.1% to 15.7%, p<0.001). In Nepal, there was a no significant trend among both men (39.1% to 31.6%, p=0.11) and women (5.6% to 4.7%, p=0.49). Conclusions: In the study countries SLT use has remained at alarmingly high levels. Usage trends do not show any signs of decline in spite of control efforts. Tobacco control measures should focus more on controlling SLT use.

Evidence shows that tobacco advertising and promotion activities may increase tobacco consumption and usage, especially in youth. Despite the regulation on prohibiting advertisement of any tobacco product, tobacco advertisement and promotion activities are still common in Vietnam. This article presents current exposure to tobacco advertising and promotion (TAP) among school children aged 13 to 15 years in Vietnam in 2014 and potential influencing factors. Data from the Global Youth Tobacco Survey 2014 in Vietnam covering 3,430 school aged children were used. Both descriptive and analytical statistics were carried out with Stata 13 statistical software. Binary logistic regression was applied to explain the exposure to TAP among youth and examine relationships with individual factors. A significance level of p<0.05 and sampling weights were used in all of the computations. In the past 30 days, 48.6% of the students experienced exposure to at least 1 type of tobacco advertising or promotion. Wearing or otherwise using products related to tobacco was the most exposure TAP type reported by students (22.3%). The internet (22.1), points of sales (19.2) and social events (11.5) were three places that students aged 13-15 frequently were exposed to TAP. Binary logistic results showed that gender (female vs male) (OR = 0.61, 95%CI: 0.52 - 0.71), susceptibility to smoking (OR = 2.12, 95%CI: 1.53 - 2.92), closest friends' smoked (OR = 1.43, 95%CI: 1.2 - 1.7) and parents smoking status (OR = 2.83, 95%CI: 1.6 - 5.01) were significantly associated with TAP exposure among school-aged children. The research findings should contribute to effective implementation of measures for preventing and controlling tobacco use among students aged 13-15 in Viet Nam.
Background: Use of smoke-less tobacco (SLT) is very common in South and South-East Asian countries. It is significantly associated with various types of cancers. The objectives of this study were to assess the proportion of hospital staff that use SLT, and to identify the factors associated with its use and their practices. Methods: In a cross-sectional study, 560 staff of two tertiary care hospitals were interviewed in the year 2009. Nurses, ward boys and technicians were counted as a paramedic staff while drivers, peons, security guards and housekeeping staff were labeled as non-paramedic staff. SLT use was considered as usage of any of the following: betel quid (paan) with or without tobacco, betel nuts with or without tobacco (gutkha) and snuff (naswar). Results: About half (48.6%) of the hospital staff were using at least one type of SLT. Factors found to be statistically significant with SLT were being a male (OR=2.5; 95% CI=1.8-3.7); having no/fewer years of education (OR=1.7; 95% CI=1.2-2.4) and working as non-paramedic staff (OR=2.6; 95% CI=1.8-3.8). Majority of SLT users were using it on regular basis, for > 5 years and keeping the tobacco products in the oral cavity for >30 minutes. About half of the users started due to peer pressure and had tried to quit this habit but failed. Conclusion: In this study, about half of the study participants were using SLT in different forms. We suggest educational and behavioral interventions for control of SLT usage.

Background: Smoking tobacco is considered as a leading cause of preventable death, mostly in developing countries like India. One of the primary goals of international tobacco control is to educate smokers about the risks associated with tobacco consumption. Tobacco warning labels (TWLs) on cigarette packages are one of the most common statutory means to communicate health risks of smoking to smokers, with the hope that once educated, they will be more likely to quit the habit. Materials and Methods: The present survey was conducted to assess the effectiveness of TWLs in communicating health risks of tobacco usage among 263 adult smokers working as bus drivers in Karnataka State Road Transport Corporation (KSRTC), Mangalore, India. Information was collected on demographic details, exposure and response to health warnings on tobacco products, intention to quit and nicotine dependency. Results: The majority (79.5%) of the respondents revealed negative intentions towards quitting smoking. Nearly half of the participants had a 'low' nicotine dependency (47.5%) and 98.1% of the respondents had often noticed warning labels on tobacco packages. These health warnings made 71.5% of the respondents think about quitting smoking. Respondents who noticed advertisement or pictures about dangers of smoking had better knowledge, with respect to lung cancer and impotence as a consequence of tobacco. A higher exposure to warning labels was significantly associated with lower nicotine dependency levels of smokers among the present study population. A significantly higher number of respondents who noticed advertisement or pictures about the dangers of smoking thought about the risks of smoking and were more inclined to think about quitting smoking. As exposure increased, an increase in the knowledge and response of participants was also observed. Conclusions: Exposure to tobacco warning labels helps to educate smokers about health risks of tobacco smoking. It may be possible to promote oral health among bus drivers by developing strategies to educate them about these risk factors.
Effects of proton beam irradiation on seed germination and growth pattern of tobacco (Nicotiana tabacum L. cv. BY-4; N. plumbaginifolia) and rice (Oryasativa L.) plants were estimated to develop the efficient conditions of irradiation. Seed germination rate was decreased by increasing the proton beam the current and the beam irradiation time in both tobacco and rice seeds. The beam irradiation conditions showing $50\%$ germination were over 60 sec at 10 nA, approximately 5 sec at 100 nA and at 500 nA beam current in tobacco seeds. And the conditions of $50\%$ germination were 60 sec at 10 nA, and 100 nA and 30 sec at 500nA in rice (cv. Dongjin 1) seeds. The growth of irradiated plants was decreased, but significant difference in morphological changes was not observed by the proton beam treatment. The proton beam is able to use as a mutagen, but some of the factors including beam size and beam detector-system must be established for efficient usage of the beam.
Background: The objective of the study was to determine the knowledge, attitude and behaviors of the practicing dentists regarding tobacco cessation counseling (TCC) in Chhattisgarh state and also the barriers that prevent them from doing so. Materials and Methods: The study was conducted among dental practitioners of Raipur district, Chhattisgarh state (India). The sampling frame was registration with the State Dental Council and practicing in Raipur district. A questionnaire was personally administered and the practitioners were given explanations regarding how to complete it. Only descriptive statistics were calculated (SPSS version 16 for Windows). Results: Based on the responding dentists' self reports, 76% were not confident in TCC, 48% did not assume TCC to be their responsibility, 17% considered that it might have a negative impact on their clinical practice, whereas 24% considered it might take away precious time from their practice, 25% considered TCC by dentists to be effective to a considerable extent and 80% considered TCC activities are not effective due to lack of formal training, 69% considered dental clinics as an appropriate place for TCC but 82% thought there must be separate TCC centre and 100% of the dentists wanted TCC training to be a part of practice and that it should be included in dental curriculum. Some 95% of them were of the view that tobacco products should be banned in India and 86% responded that health professionals must refrain from tobacco habits so to act as role models for society. Conclusions: Dental professionals must expand their armamentarium to include TCC strategies in their clinical practice. The dental institutions should include TCC in the curriculum and the dental professionals at the primary and the community health care level should also be trained in TCC to treat tobacco dependence.
Background: Association of angiotensin converting enzyme (ACE) gene polymorphisms with lung cancer susceptibility remains uncertain and varies with ethnicity. Northeast India represents a geographically, culturally, and ethnically isolated population. The area reports an especially high rate of tobacco usage in a variety of ways of consumption, compared with the rest of the Indian population. Materials and Methods: We conducted a population based case control study in two major high risk region for lung cancer from Northeast India. A total of 151 consecutive lung cancer cases diagnosed histopathologically and equal numbers of controls were recruited with record of relevant sociodemographic information. Blood samples were collected and processed to identify ACE gene polymorphism. Results: Significantly higher (40.4 % vs 29.1%, OR=1.97, CI=1.04-3.72; p=0.037) prevalence of the ACE II genotype was observed among lung cancer cases. Smoking was significantly associated with increased risk of lung cancer (OR=1.70, CI=1.02-2.81; p=0.041). An enhanced risk was also observed for interaction of ACE II genotype with tobacco smoking (OR=4.09, CI=1.51-11.05; p=0.005) and chewing (OR=3.68, CI=1.22-11.13; p=0.021). Conclusions: The present study indicates significant association s of the ACE II genotype with lung cancer in high risk Northeast India.
