The impact of traditional smokers versus electronic cigarette smokers on periodontal parameters in iraqi males / O impacto do uso de cigarros tradicionais versus uso de cigarros eletrônicos nos parâmetros periodontais em homens iraquianos

Objective: To compare the effects of vaping and cigarette smoking and indicate their impact on periodontal health. Material and Methods: A total of 90 subjects divided into three groups. Group I: 30 Traditional cigarettes smoker who have smoked up to 10 cigarettes, Group II: 30 electronic cigarettes subjects who have been using vape at least one year and never smoke, and Group III: 30 subjects who have no smoking history. Using a mirror and a periodontal probe, periodontal parameters (plaque index, gingival index, probing depth and clinical attachment loss) were used to evaluate periodontal health. Results: The findings showed that the periodontal parameters had a highly significant differences at P ≤ 0.01 between traditional and electronic smoking groups. While clinical attachment loss demonstrated non-significant difference P ≥ 0.05 in comparison between electronic cigarettes and the group who never smoke. Conclusion: The results of this study suggested that traditional cigarettes and electronic cigarettes both had unfavorable impact on periodontal health status, never the less quit smoking showed positive impacts on periodontal parameters (AU)

Objetivo: O objetivo foi comparar os efeitos do uso do cigarro eletrônico e do cigarro convencional, indicando seus impactos na saúde bucal. Material e Método: 90 indivíduos foram divididos igualmente em três grupos: Grupo I, usuários de cigarro convencional que fumaram até 10 cigarros por dia; Grupo II: usuários de cigarro eletrônico que utilizam este por pelo menos há 1 ano e não fumavam antes disso; Grupo III: usuários sem qualquer história de hábitos tabagistas. Utilizando um espelho bucal e uma sonda periodontal, parâmetros periodontais (índice de placa, índice gengival, profundidade de sondagem e perda de inserção clínica) foram coletados para avaliar a saúde periodontal. Resultados: As evidências mostraram que os parâmetros periodontais apresentaram diferença significativa (P ≤ 0.01) entre os grupos I e II. Conclusão: Os resultados deste estudo sugerem que tanto o uso de cigarro convencional como o de cigarro eletrônico possuem impactos desfavoráveis na saúde periodontal, e que a cessação do uso destes mostraram impactos positivos nos parâmetros periodontais(AU)

O que a Pesquisa Nacional de Saúde tem a dizer sobre a influência do gasto com cigarro no rendimento domiciliar? / What does the Brazilian National Health Survey have to say about the influence of cigarette spending on household income? / ¿Qué dice la Encuesta Nacional de Salud brasileña sobre la influencia del gasto en cigarrillos en los ingresos del hogar?

Em um Brasil no qual os indicadores de empobrecimento da população seguem aumentando, preocupa o fato de que indivíduos gastem dinheiro para comprar cigarro em vez de usarem esse recurso em ações que fortaleçam aspectos do bem-estar de suas jornadas de vida e de suas famílias. Estimou-se, a partir da Pesquisa Nacional de Saúde de 2019, a influência que o gasto com cigarro industrializado teve no orçamento familiar nos domicílios com pelo menos um fumante, estratificada por características sociodemográficas. Os fumantes brasileiros destinaram cerca de 8% do rendimento médio mensal domiciliar per capita para a compra de cigarros industrializados. O percentual do gasto médio mensal chegou a quase 10% desse rendimento, entre os fumantes de 15 a 24 anos, e foi ainda maior para aqueles com Ensino Fundamental incompleto (aproximadamente 11%). Nas regiões Norte e Nordeste do país, esse gasto ultrapassou os 9%. O estado com o maior comprometimento da renda domiciliar foi o Acre (13,6%), seguido por Alagoas (11,9%), Ceará, Pará e Tocantins (todos com aproximadamente 11%). Nossos achados reforçam, portanto, a importância de fortalecer a implementação de medidas efetivas de redução da proporção de fumantes, tal como a política tributária. Dessa forma, o dinheiro que atualmente é destinado pelos indivíduos à compra de cigarros poderá ser revertido no atendimento de suas necessidades básicas, contribuindo para a promoção da saúde e melhoria da qualidade de vida.

In a country whose indicators of population impoverishment continue to increase, it is concerning that individuals spend money to buy cigarettes instead of using this resource in actions that strengthen aspects of the well-being of their lives and that of their families. Based on the Brazilian National Health Survey conducted in 2019, the influence of spending on manufactured cigarettes on the family budget in households with at least one smoker was estimated, stratified by sociodemographic characteristics. Brazilian smokers allocated around 8% of their average per capita monthly household income to the purchase of manufactured cigarettes. The percentage of average monthly expenditure on cigarettes reached almost 10% of this income among smokers aged 15 to 24 and was even higher for those with incomplete elementary education (approximately 11%). In the North and Northeast regions of the country, this expenditure exceeded 9%. The state with the most significant impact on household income was Acre (13.6%), followed by Alagoas (11.9%), Ceará, Pará, and Tocantins (all with approximately 11%). Our findings, therefore, reinforce the importance of strengthening the implementation of effective measures, such as tax policy, to reduce the proportion of smokers. Thus, the money that individuals currently allocate to purchase cigarettes can be used to meet their basic needs, contributing to the promotion of health and improving the quality of life.

En un Brasil donde los indicadores de empobrecimiento de la población siguen aumentando, es preocupante el hecho de que las personas gasten dinero para comprar cigarrillo en lugar de usarlo en acciones para fortalecer los aspectos del bienestar de sus vidas y la de sus familias. A partir de la Encuesta Nacional de Salud brasileña realizada en 2019, se estimó la influencia del gasto en cigarrillo industrializado en el presupuesto familiar de los hogares donde vivía al menos un fumador, estratificado por características sociodemográficas. Los fumadores brasileños destinaron alrededor del 8% del ingreso per cápita mensual promedio del hogar para la compra de cigarrillos industrializados. El porcentaje del gasto mensual promedio en cigarrillos alcanzó casi el 10% de este ingreso entre los fumadores de 15 a 24 años y fue aún mayor para los que tenían educación primaria incompleta (aproximadamente el 11%). En el Norte y Nordeste del país, ese gasto superó el 9%. El estado con un mayor compromiso con los ingresos del hogar fue Acre (el 13,6%), seguido por Alagoas (el 11,9%), Ceará, Pará y Tocantins (todos con aproximadamente el 11%). Por lo tanto, nuestros resultados resaltan la importancia de fortalecer la implementación de medidas efectivas para reducir la proporción de fumadores, tal como la política tributaria. Así, el dinero que actualmente las personas destinan a la compra de cigarrillos podría utilizarse en la atención de sus necesidades básicas, contribuyendo a promover la salud y la mejora de la calidad de vida.

Effect of fumigation therapy of Flos Farfarae in cigarette smoke-induced lung injury mice based on metabolomics / 药学学报

This study aimed to investigate the effect of Flos Farfarae (FF) fumigation on cigarette smoke-induced lung injury mice, and analyze the metabolic profile of lung tissue by metabolomics. All animal experiments were conducted under the guidance and approval of the Animal Ethics Review Committee of Shanxi University (Approval number: SXULL2019014). By using HS-GC-MS to analyze volatile components of Flos Farfarae, 23 compounds were identified. The results showed that FF fumigation improved the lung tissue morphology of cigarette smoke-induced lung injury mice, lowered the levels of interleukin 6 (IL-6) and interleukin-1β (IL-1β). The lung tissue samples were applied for metabolomic analysis based on UHPLC-QTOF MS, the results showed that 70 metabolites were changed in the lung tissue of mice after cigarette exposure, and 35 of them could be regulated, including lysophosphatidylcholine (LPC), 12-HETE, adenosine, and xanthine. These metabolites, such as LPC, 12-HETE, adenosine, and xanthine were mainly associated with the body's inflammatory response. It was observed that these metabolites are primarily involved in purine metabolism, arachidonic acid metabolism, phospholipid metabolism, and pyruvate metabolism pathways. These findings suggest that the volatile terpenoids in the FF may regulate the metabolites associated with the inflammatory response in the lung tissue, such as lysophosphatidylcholine, 12-HETE, and adenosine, which could further alleviate lung inflammation induced by cigarette smoke through the metabolic pathways of purine metabolism and others. This study proved the scientific basis of the traditional application of FF fumigation, and provided a theoretical basis for the further product development.

Electronic cigarettes: a new social practice and the challenge of tobacco control policies / Cigarros eletrônicos: uma nova prática social e o desafio das Políticas de controle do tabagismo

O tabagismo é uma doença crônica e é considerado um grave problema de saúde pública e tem sido alvo ao longo do tempo de muitas ações preventivas e de promoção à saúde. O produto do tabaco mais consumido entre adultos e jovens é o cigarro convencional, entretanto, o consumo de tabaco sem fumaça ou outros produtos do tabaco fumado, como os cigarros eletrônicos, tem sido observado de forma crescente no mundo. Os dispositivos eletrônicos para fumar (DEF), que têm despertado cada vez mais a atenção de consumidores jovens, envolvem diferentes equipamentos e tecnologias. Fundamentado no princípio da precaução, desde 2009, o Brasil proibiu a comercialização, importação e propaganda de todos os tipos de DEF que oferecessem a substituição de cigarro, cigarrilha, charuto, cachimbo e similares ou que objetivem alternativa ao tratamento do tabagismo, por meio da RDC n 46, de 28 de agosto de 2009. Mesmo proibido no Brasil, evidencia-se o uso dos cigarros eletrônicos como uma alternativa, revelando um novo desafio a ser enfrentado pelas políticas de controle do tabagismo. As lacunas de conhecimento inerentes a uma prática social nova, bem como da necessidade de construção de referenciais que contribuam para a melhor tomada de decisões, seja no âmbito da intervenção profissional ou da gestão das políticas públicas, com vistas a proteger a saúde da população, por si só já torna relevante a ampliação de conhecimentos acerca desta temática. Contudo, é necessário a compreensão de que as ações de prevenção, promoção e controle devem ser compreendidas de forma transversal e interdisciplinar, a fim de que se possa refletir sobre os processos que envolvem aspectos políticos, socioeconômicos e culturais que interagem diretamente com o processo saúde-doença. Deste modo, com base na problemática apresentada e considerando a relevância da temática em questão, como campo pouco enfrentado deste âmbito, destaca-se que a ampliação de investigações e o aprofundamento de discussões sobre ela, possibilitarão uma melhor compreensão e visibilidade do problema

Smoking is a chronic disease and is considered a serious public health problem and has been the target of many preventive and health promotion actions over time. The most consumed tobacco product among adults and young people is the conventional cigarette, however, the consumption of smokeless tobacco or other smoked tobacco products, such as electronic cigarettes, has been observed on an increasing basis in the world. Electronic smoking devices (EFD), which have increasingly attracted the attention of young consumers, involve different equipment and technologies. Based on the precautionary principle, since 2009, Brazil has prohibited the sale, importation and advertising of all types of DEF that offer the replacement of cigarettes, cigarillos, cigars, pipes and the like or that aim at an alternative to the treatment of smoking, through RDC n 46, of August 28, 2009. Even though it is prohibited in Brazil, the use of electronic cigarettes as an alternative is evident, revealing a new challenge to be faced by tobacco control policies. The knowledge gaps inherent to a new social practice, as well as the need to build references that contribute to better decision-making, whether in the scope of professional intervention or the management of public policies, with a view to protecting the health of the population, for itself already makes the expansion of knowledge about this theme relevant. However, it is necessary to understand that prevention, promotion and control actions must be understood in a transversal and interdisciplinary way, so that one can reflect on the processes that involve political, socioeconomic and cultural aspects that interact directly with the health process -illness. Thus, based on the problem presented and considering the relevance of the issue in question, as a field little faced in this area, it is emphasized that the expansion of investigations and the deepening of discussions about it, will allow a better understanding and visibility of the problem.

Addiction to Tobacco Smoking and Vaping

ABSTRACT The tobacco epidemic has been one of the biggest public health threats, and smoking is one of the world's largest preventable causes of premature death. An estimated 15.4% of all deaths in the world are attributable to tobacco smoking. The present review aims to describe addiction to tobacco smoking and vaping. Tobacco and vaping devices contain nicotine, a highly addictive drug, which explains why smoking is so prevalent and persistent. Electronic cigarettes are a group of novel nicotine or tobacco products that have rapidly gained popularity in recent years. Electronic cigarette devices allow for the use of other drugs, including THC, while the lax regulation may allow for the introduction of toxic compounds that can lead to acute or subacute toxicity, such as the e-cigarette- or vaping-associated lung injury that has been linked to vitamin E acetate. In addition, regular vapers and heated tobacco devices emit toxins, although at lower concentrations than burned tobacco. However, more and more side effects have been identified. No new effective treatment for nicotine addiction has been developed recently, despite its huge adverse impact on overall health and other outcomes. As for the primary line of medications, the last one started in 2006, the varenicline, demonstrating a low interest in developing new medications against smoking, an unacceptable state of affairs, given the huge impact of smoking on morbidity and mortality.

Morphological Effects of Cigarette Smoking on Respiratory System and Related Functions Based on AQPs Expression

SUMMARY: A great deal of attention of air pollution on respiratory health is increasing, particularly in relation to haze days. It is that exposure to cigarette smoke augments the toxicity of common air contaminants, thereby increasing the complexity of respiratory diseases. Although there are various mechanisms involved to respiratory diseases caused or worsen by cigarette smoking, in which the role of AQPs in the lung with regard to fluid homeostasis still remains elusive. In this paper, we copied the rat models based on smoke generator, and investigated the morphological changes of mucosa and related functions depending on the balance of lining liquid of alveoli via AQPs expression. Compared with normal group, weak labelling of AQP1 and AQP5 protein abundance were clearly detected in the corresponding part of smoke exposure groups compared with normal group. Hence, it is suggested that the contribution of AQPs in the lung is diminished, thereby causing perturbed balancing between resorptive and secretory fluid homeostasis under cigarette smoking.

Cada vez se presta más atención a la contaminación del aire en la salud respiratoria, particularmente, en relación con los días de neblina. En consecuencia la exposición al humo del cigarrillo aumenta la toxicidad de los contaminantes comunes del aire, lo que además aumenta la complejidad de las enfermedades respiratorias. Aunque existen varios mecanismos involucrados en las enfermedades respiratorias causadas o empeoradas por el tabaquismo, en las que el papel de las AQP en el pulmón respecto a la homeostasis de líquidos sigue siendo difícil de alcanzar. En este artículo, copiamos los modelos de rata basados en el generador de humo e investigamos los cambios morfológicos de la mucosa y las funciones relacionadas según el equilibrio del líquido de revestimiento de los alvéolos a través de la expresión de AQP. En comparación con el grupo normal, se detectó claramente un etiquetado débil de la abundancia de proteínas AQP1 y AQP5 en la parte correspondiente de los grupos de exposición al humo en comparación con el grupo control. Por lo tanto, se sugiere que la contribución de las AQP en el pulmón está disminuida, provocando así un equilibrio perturbado entre la homeostasis del líquido secretor y de reabsorción bajo el hábito de fumar cigarrillos.

Effect-of-cigarette-smoking-in-development-of-dental-caries-a-cross-sectional-study

Background: Cigarette smoking is a major public health challenge globally. It not only affects the general health but also impacts the oral health. It causes an array of oral health lesions including dental caries which causes pain and infection and can result in the requirement of the tooth to be extracted. The aim of the study is to investigate theAim: relationship of cigarette smoking and dental caries in the adult population in the city of Hyderabad. Materials and Methods: This study was conducted by OroGlee Solutions Private Limited, Hyderabad. A total of 1019 subjects aged 18 to 60 years were examined. Oral examination was done using intraoral camera, mouth mirror and torch. Results: Percentage of smokers having dental caries was 89.4% and percentage of non smokers having dental caries was 81.8%. Chi square test was used to determine the significance of difference between the prevalence of caries in smokers and prevalence of caries in non smokers. It showed a statistically significant correlation between dental caries and smoking cigarette. Smoking leads to multiple oral health problems including high incidence of dental caries. TheConclusion: incidence of dental caries further increases in presence of coexisting factors such as poor oral hygiene, food habits, limited preventive dental visits and old age.

Estudio cualitativo del uso de los cigarrillos electrónicos en los estudiantes universitarios / Qualitative Study of E-Cigarette Use in College Students

Objetivos: El propósito de esta investigación fue determinar el nivel de conocimiento, creencias, percepción y practicas asociadas al consumo de cigarrillos electrónicos en los estudiantes universitarios (UASD), recinto Santiago, República Dominicana. Cada estudiante firmó un consentimiento informado certificando que éste respondió cada pregunta realizada por el entrevistador de manera voluntaria. El método de recolección de los datos fue mediante entrevistas, las cuales fueron grabadas por los entrevistadores. La muestra fue de 53 entrevistas, 48 individuales y 5 grupos focales, la misma se tomó hasta alcanzar el punto de saturación de cada pregunta, es decir cuando todas las respuestas se tornaron repetitivas. Materiales y métodos: Se realizó un estudio cualitativo de tipo fenomenológico y de fuentes primarias en el período mayo-agosto del año 2019 en la universidad privada Pontificia Universidad Católica Madre y Maestra (PUCMM) y la universidad pública Universidad Autónoma de Santo Domingo. (UASD), campus Santiago, República Dominicana. El método de recolección de datos se realizó a través de entrevistas, las cuales fueron grabadas por los entrevistadores. Cada estudiante entrevistado firmó un consentimiento informado certificando que respondió voluntariamente a cada pregunta formulada por el entrevistador. La muestra estuvo compuesta por 53 entrevistas, 48 personas y cinco grupos focales. Las entrevistas se realizaron hasta llegar al punto de saturación de cada pregunta, que es cuando todas las respuestas se volvieron repetitivas. Resultados: El conocimiento que tiene los estudiantes universitarios sobre cigarrillo electrónico (CE), es pobre, desde su funcionamiento, partes, sustancias e incluso las posibles complicaciones que puede traer a la salud, tanto en la Pontificia Universidad Católica Madre y Maestra (PUCMM) como en la Universidad Autónoma de Santo Domingo (UASD), pero es más notable en la universidad pública. Por otro lado, muchos perciben el CE, como una alternativa del uso de tabaco, que posee diversidad de sabores, olor agradable, atractivo, práctico y capaz de ofrecer relajación. En cuanto a la actitud hacia el dispositivo, en PUCMM exhibe un mayor nivel de rechazo con respecto al uso. Es importante mencionar, que mayoría de los entrevistados son o alguna vez fueron usuarios de este, no obstante, no lo recomiendan en gran medida, ya que asumen que puede causar daño y ser adictivo, aunque en menor medida al cigarrillo convencional. La población más susceptible a su uso, son los jóvenes y el sexo masculino, aunque las féminas se han ido sumando de manera significativa. De igual modo, se logró apreciar las grandes influencias que mueven a los jóvenes a su consumo, incluyendo, las redes sociales, familia, amigos, en general el entorno en que se rodean. Conclusión: Concluimos que los estudiantes universitarios carecen de conocimiento con respecto al cigarrillo electrónico, tanto en el funcionamiento, sustancias y complicaciones para la salud. Muchos observan al cigarrillo electrónico como un dispositivo para fumar con un olor agradable, por lo cual puede ser muy atractivo para los usuarios. Se logró apreciar el importante papel que juegan las influencias sociales para el uso del dispositivo, promovido por las redes sociales y relaciones cercanas. Otro problema en la sociedad actual es el uso de CE en menores de edad. Según los resultados existe una gran necesidad de intervención y educación, principalmente en los jóvenes.

Objective: The purpose of this research was to determine the level of knowledge, beliefs, perception, and practices associated with consuming electronic cigarettes among university students. Materials and methods: A qualitative study of phenome-nological type and from primary sources was carried out in the period of May-August of the year 2019 at the private university Pontificia Universidad Católica Madre y Mae-stra (PUCMM) and the public university Universidad Autónoma de Santo Domingo (UASD), Santiago campus, Dominican Republic. The data collection method was done through interviews, which the interviewers recorded. Each student interviewed signed an informed consent cer-tifying that they answered voluntarily each question asked by the interviewer. The sample consisted of 53 interviews, 48 individuals, and five focus groups. Interviews were done until reaching the saturation point of each question, which is when all the answers became repetitive. Results: University students' knowledge regarding elec-tronic cigarettes (EC) is poor. Knowledge regarding its mechanism, parts, substances, and possible complications to one's health, is scarce both in PUCMM and the UASD, but this is more notable at the public university. Addition-ally, many perceive EC as an alternative to tobacco use, the former, as per our study population, having a variety of fla-vors, a pleasant smell, being attractive, practical, and capa-ble of offering relaxation. Regarding the attitude towards the device, PUCMM exhibits a higher level of rejection regarding its use. It is essential to mention that most inter-viewees were once users of EC. However, they do not rec-ommend it to a great extent since they assume that it can cause harm and be addictive, although to a lesser extent than conventional cigarettes. The population most suscep-tible to its use are young people, including minors and the male gender, although females have been significantly increasing its use. Similarly, it was possible to appreciate the influences that greatly evoke the younger population's consumption, including social networks, family, friends, and the surrounding environment. Conclusion: We concluded that university students have insufficient knowledge regarding electronic cigarettes, both in their mechanism, substances, and health compli-cations. Most see electronic cigarettes as smoking devices with a pleasant smell, which can be very attractive to users. It was possible to observe the critical role played by social influences on the use of the device, promoted by social networks and close relationships. Another problem in cur-rent society is the use of CE in minors. According to the results, there is a great need for intervention and educa-tion, mainly among the younger generation.

Does bullying due to oral conditions influence cigarette smoking in adolescents? A structural equation modeling

Abstract This study aimed to explore the pathways that can influence cigarette smoking among adolescents. This population-based cohort followed a random sample of 12-year-old adolescents from southern Brazil for 6 years. Regular cigarette smoking was assessed through a self-reported question, previously used in the Brazilian National Survey of Scholar Health. We also gathered data on bullying, dental caries at baseline, incidence of caries, sex, friend network, and Sense of Coherence (SOC). Socioeconomic and demographic characteristics were also collected. Structural equation modeling was used to evaluate the pathways. Of the 1,134 adolescents examined at baseline, 768 were re-evaluated (67.7% retention rate). The prevalence of smoking was 37.6%. This prevalence was directly affected by low SOC (SC: -0.14, p < 0.01), low household income (SC: -0.12, p < 0.01), and male sex (SC: 0.15, p < 0.01). Presence of dental caries at baseline indirectly influenced the occurrence of dental bullying at follow-up via the incidence of dental caries (SC: 0.01, p < 0.05). Dental bullying indirectly influenced cigarettes consumption via SOC (SC: 0.62, p < 0.05). Friend network also indirectly influenced the consumption of cigarettes via SOC (SC: 0.32, p < 0.05). Psychosocial factors influence adolescent cigarette consumption through its higher direct and indirect effects (via bullying). In addition, behavioral, sociodemographic, and clinical factors also influence the occurrence of smoking.

Barriers to the provision of smoking cessation intervention/services: A mixed-methods study among health care workers in Zambezi region, Namibia

Background. Healthcare workers (HCWs) can play a significant role in tobacco prevention by delivering smoking cessation (SC) interventions to patients who smoke. Objective: To identify and explore the perceived barriers which prevent healthcare workers from delivering SC counselling to patients in Zambezi region, Namibia. Methods: A regional-based, concurrent mixed-methods study was conducted between March and October 2020 among HCWs of the 8 constituencies of Zambezi region, Namibia. In the study, 129 respondents, who had been residents of the selected constituencies for over 5 years and aged between 17 to 60 years, participated. Results: 129 respondents participated in the study. Majority of respondents were females (62.9% and 68.1%) compared to (37.1% and 31.9%) males. The mean age of respondents was 35.91 (SD=9.3) and 36.61 (SD=8.7) respectively and their ages ranged between 18 and 59 years. Key barriers were identified: (i) HCWs based barriers included lack of time to provide SC, inadequate training and insufficient knowledge on SC interventions; (ii) system-based barriers identified lack of SC guidelines and educational materials for patients, and specialists to refer patients; and (iii) patient/client-based barriers included lack of patient interest in SC information, patients not adhering to advise given on SC. Conclusions: This study showed that SC delivery in Zambezi region is inadequate. Barriers were identified regarding the delivery of SC intervention for the first time. Targeted SC interventions are required to combat these identified specific barriers. There is a crucial need to improve HCWs skills and knowledge in providing SC intervention.

Effect of zinc and probiotics supplementation on IL-6 and tissue neutrophil levels in rats exposed to cigarette smoke

@#Introduction: Cigarette smoke exposure can cause inflammation, inducing the release of acute phase cytokines, such as IL-6, that will then trigger the recruitment of neutrophils, which are mostly phagocytic cells. Zinc and probiotics are known to have beneficial effects against inflammation. This study was conducted to investigate the effect of zinc and probiotics supplementation on IL-6 and tissue neutrophil levels in rats exposed to cigarette smoke. Methods: In a randomised, experimental study with post-test control group design, thirty 2 to 3-month-old male Wistar rats, each weighing 180-220 g, were divided into five groups: control group without treatment (C); exposed to cigarette smoke [C (-)]; exposed to cigarette smoke and received zinc (Z); exposed to cigarette smoke and received probiotics (P); and exposed to cigarette smoke and received a combination of zinc and probiotics (ZP). Results: Mean tissue neutrophil levels in Z, P, and ZP groups were 43.43±2.01, 34.67±1.32,and 29.77±5.05 cells, respectively. There were significant differences between supplementation intake and tissue neutrophil levels in each group compared to C (-) group (p<0.05). Meanwhile, only IL-6 level in the ZP group (6.02 pg/mL) decreased significantly compared to C (-) group (10.61 pg/mL). Conclusion: These results suggest that a combination of zinc and probiotics have an anti-inflammatory effect as measured by IL-6 and neutrophil levels.

High and low frequency repetitive transcranial magnetic stimulation in smoking cessation: A systematic review

Abstract@#Repetitive Transcranial Magnetic Stimulation is a non-invasive brain stimulation process popularly used to treat psychiatric disorders. Multiple evidence shows effectiveness of rTMS in treating addiction, particularly in tobacco or cigarette users. This study consisted of review of current published literatures on repetitive transcranial magnetic stimulation following predefined eligibility criteria. The studies included evaluated at least one of the epidemiological parameters: (i) the meaning of repetitive transcranial magnetic stimulation (ii) Effectiveness of the Repetitive Transcranial Magnetic Simulation Over Behavioral therapy (iii) rTMS-associated adverse events among tobacco users@*Methodology@#We included published studies discussing rTMS in smoking cessation which examined if these interventions were effective and identified whether it has a severe negative effect on the patients. A total of 104 related studies were identified through database searches (Pubmed, Elsevier, Cochrane). Of which, 53 duplicate studies were removed. Five studies were then excluded with more than 10 years in publication. A total of 28 papers were then included in the study.@*Conclusion@#We conclude that rTMS is more effective in treating addiction in terms of smoking compared to behavioral therapy and rTMS affects triggered desired circuit which may be crucial among tobacco users. Individual neuronal excitability in the specific region’s subsequent induction may impact the therapeutic outcomes. With this, the high-frequency rTMS sequentially applied to the left superior medial frontal cortex and dorsolateral prefrontal cortex may be an effective tool for improving the cessation rate.

Vaping and e-cigarettes: a new public health concern / Монголын Анагаах Ухаан

@#Electronic cigarettes are handheld electronic vaping devices which produce an aerosol by heating an e-liquid. The e-liquid typically contains humectants and flavorings, with or without nicotine; once vaporized by the atomizer, the aerosol (vapor) provides a sensation like tobacco also smoking the heating process can lead to the generation of new decomposition compounds that may be hazardous. Heavy metals, organic compounds, and particles smaller than PM2.5 were found on the puff of the electronic cigarette, also in 2012 International agency research cancer, introduced PM2.5 human carcinogen substance. Therefore, e-cigarette liquid products should be subjected to regulatory control to ensure consistent nicotine delivery. Global youth tobacco survey Mongolia 2019 asked about e-cigarette use status and 3.5% (95% CI: 2.6-4.6) of students currently used electronic cigarettes while one in ten students (10.1%, 95% CI: 8.3-12.2) had ever used electronic cigarettes. E-cigarette advertising is on television and radio in many countries that have long banned similar advertising for cigarettes and other tobacco products and may be indirectly promoting smoking conventional cigarettes. Smoke-free policies protect nonsmokers from exposure to toxins and encourage smoking cessation. Introducing e-cigarettes into clean air environments may result in population harm if use of the product reinforces the act of smoking as socially acceptable or if use undermines the benefits of smoke-free policies.
