Background and Aims: There is little information about the epidemiology and risk factors of periodontal diseases in Latin America in general, and Brazil in particular. The principal aims of this study were to: 1) describe the prevalence and severity of periodontal attachment loss and gingival recession, and to assess the contribution of demographic, behavioral, and environmental exposures to the occurrence of periodontal disease outcomes in a sample representative of the urban population in the state of Rio Grande do Sul in south Brazil; and 2) report the epidemiology and risk indicators of aggressive periodontitis in this population. Methods: A representative sample consisting of 1,586 subjects 14-103 years of age (mean 38 y) and comprising 45.3% males and 54.7% females was selected using a multi-stage, probability, cluster sampling strategy. The subjects were interviewed using a structured questionnaire and underwent a full-mouth, six sites per tooth clinical examination in a mobile examination center. Results: Moderate and severe clinical attachment loss and gingival recession were widespread among adults in this population. The prevalence and extent of attachment loss ³5 and ³7 mm were 79% and 52% subjects, and 36% and 16% teeth; and for gingival recession ³3 mm and ³5 mm were 52% and 22% subjects, and 17% and 6% teeth, respectively. Aggressive periodontitis was diagnosed in 5.5% of subjects, which is significantly higher than the reported prevalence in most other populations. Among the main risk indicators for chronic as well as aggressive destructive periodontal diseases were: older age, low socioeconomic status, dental calculus, and smoking. Cigarette smoking accounted for an important part of periodontal disease burden, particularly in adults, and should be considered an important target in any prevention strategy aimed at reducing the burden of periodontal diseases. Partial recording methods consistently underestimated the prevalence of attachment loss in the population, and the extent of underestimation was dependent on the type of system used and the threshold of attachment loss. Conclusions: Destructive periodontal diseases are prevalent in this Brazilian population. Suitable disease prevention and health promotion programs should be established to improve the periodontal health in this population.

The thesis is focusing on the influence of organized physical activities on the smoking and alcohol drinking by the kids between 12 and 16 years of age. The basic characteristics of organized physical activities, smoking and alcohol drinking are described in the theoretical part of the thesis where emphasis is put on children and youth.The sociological, psychological and biological views are included in the basic characteristics. The research in the practical part of the thesis was done by a questionnaire. The total number of interviewee was 216. The amount of physical activities, smoking and alcohol drinking by kids between 12 and 16 years of age was charted, once the data collected was statistically evaluated and put into connection with membership in a sports club.The research clearly shows that children registered in a sports club are less likely to smoke or consume alcohol.

The thesis topic bears the name: "Aspect of smoking among students of high medical schools". Smoking is one the most often appearing drug addictions nowadays in Europe. With reference to the World Health Organization, there are 1.3 billion of smoking people in the world today whereas consequences of smoking kill approximately 4.8 million of people every year, which are 560 people each hour. If the current trend continues, then in the current pace 10 million of people will die of the consequences of cigarette smoking during the year of 2020. Smoking invokes an enormous addiction to nicotine which bears itself considerable economic, social and health problems. There were some students from 1st and 4th grade of the present form of studies of all high medical schools selected. Those were students particularly from the schools: SZŠ and VOŠZ České Budějovice, SOŠZ and SOU Český Krumlov, SZŠ Jindřichův Hradec, SZŠ Tábor and SZŠ Písek. In total, 591 of students were responded whereas most of them were girls (87%). The average age of the responded ones was 17 years. The thesis consists of theoretical and empirical parts. The theoretical part deals with history of cigarette smoking, a definition of drug addiction, chemical composition of cigarette smoke and malignity of individual toxic elements. Further, there is a chapter concerning problem issues of electronic cigarette smoking in the theoretical part. In the conclusion of this part of the thesis, there are some statistical data referring to cigarette smoking stated. There are some findings of quite a few of authors dealing with problem issues of cigarette smoking and addiction to nicotine summarized here. The empirical part consists of findings from my own research analysis which was done with the intention to map the prevalence of smoking among future health workers and their opinion to cigarette smoking among healthcare staff and people preparing for their healthcare career. There are also the respondents' opinions and attitudes included. The aim of the thesis was: 1.: To find the prevalence of smoking of 1st and 4th grade of high medical schools students. 2.: To find what influence the respondents' surroundings have on the fact of their smoking. 3.: To find what attitude high medical school students have to healthcare staff smoking cigarettes. To reach the above mentioned aims, there were three hypotheses determined: H1: There is a statistically significant difference existing in the prevalence of smoking at 1st and 4th grade of high medical school students. H2: There is a statistically significant difference existing in the prevalence of cigarette smoking among students coming from families where at least one member smokes. H3: There are statistically significant differences in the attitude of 1st and 4th grade students to cigarette smoking among healthcare workers. To prove or disprove the mentioned hypotheses there is a method of quantitative research selected. A questionnaire was used to collect the data. The questionnaires including 23 questions were distributed among 591 students of high medical schools of the South Bohemia Region. Their rate of return was 85%. The collected data were processed in the form of transparent graphs and the hypotheses were statistically tested. Pursuant to the evaluation of respondents' answers including the statistical data testing were proved by the hypothesis which presumed that there were statistically significant differences in the prevalence of cigarette smoking 1st and 4th grade students. The difference really exists that the 4th grade students smoke more often. It is interesting that the most considerable difference is between the schools of SZŠ and VOŠZ České Budějovice. On the contrary, the percentage of smoking students of SOŠZ Český Krumlov in the 1st grade is considerably high. Hypothesis no. 2 was statistically proved as well. There is a real significant difference exist

This diploma thesis deals with aspects of breaking the habit of smoking. My thesis consists of theoretical and practical part. The theoretical part is divided into three main chapters: smoking, impact of smoking and breaking of the smoking habit. I also defined the history of smoking, type of tobacco consuming, addiction to tobacco, treatments of the addiction, negative aspects of smoking etc. Practical part consists of quantitative research through questionnaires. The aim of my thesis was to find out what is tobacco addiction, gather the information and experience from the smokers who had experience with breaking their habit, analyze the methods of breaking the smoking habit and explain their main motivations for quitting the smoking. I have also included statistic data of my research.

Os vieses atencional e avaliativo para imagens relacionadas ao cigarro foram mensurados após a exposição a imagens relacionadas ao álcool (IA) ou controle (IC) através de uma tarefa de atenção visual. Participaram 40 universitários de 19 a 30 anos (M=23 anos) bebedores fumantes designados aleatoriamente para a condição IA ou IC. Além dos vieses, foram avaliados: beber problemático (através do Alcohol Use Disorders Identification Test), e severidade da dependência de nicotina (Questionário de Tolerância e Fagerstron). Os fumantes apresentaram viés atencional e avaliativo para as imagens relacionadas ao fumar. A exposição prévia a pistas associadas ao beber elevou o viés avaliativo (mas não o atencional) para imagens relacionadas ao cigarro. Observou-se alta freqüência de bebedores problemáticos, porém, baixo grau de dependência em nicotina. As implicações destes resultados para a prevenção ao fumo e ao beber abusivo entre universitários foram discutidas. / This study applied a visual attentional task to evaluated the attentional and evaluative biases for smoking-related images after exposure to alcohol (IA) or control (IC) images. Subjects were 40 college drinker and smokers (19 to 30 years old, mean 23 yrs), randomly assigned for IA or IC conditions. Also problem drinking (Alcohol Use Disorders Identification Test) and severity of nicotine dependence (Questionário de Tolerância de Fagerströn) were assessed. Smokers showed attentional and evaluative biases for smoking-related images. Previous exposure to drinking cues increased the evaluative but not the attentional bias for smokingrelated images. There was a high frequency of problem drinkers, but a low degree of nicotine dependence in this sample. The implications of these findings for prevention of smoking and abusive drinking among college students were discussed.

Introdução: A psoríase é uma doença inflamatória crônica, que afeta a pele, couro cabeludo, unhas e ocasionalmente as articulações. A prevalência da psoríase varia de 0,6 a 4,8% na população mundial, afetando homens mulheres igualmente. A doença tem sido associada a um maior risco de desenvolvimento de várias comorbidades. O objetivo desse estudo é avaliar a associação entre psoríase e a presença de comorbidades como hipertensão, diabetes, dislipidemia, obesidade, depressão e os hábitos de fumar e ingerir bebidas alcoólicas. Métodos: Estudo caso-controle (psoríase x não psoriásicos) realizado no ambulatório de Dermatologia do Hospital de Clínicas de Porto Alegre. Foram avaliados os parâmetros de: peso, altura, pressão arterial, circunferência abdominal e diagnóstico de comorbidades. Nos pacientes com psoríase avaliou-se também a estimativa da área corporal acometida. Resultados: O estudo incluiu 350 casos (55,1% mulheres) e 346 controles (63,6% mulheres). A média de idade dos casos em anos foi 49,81 e nos controles 48,5. Os fatores de riscos que apresentaram diferença significativa entre casos e controles estudados foram: cintura abdominal aumentada com p<0,01 e OR=2,1 (IC 95%1,3-3,3); o Índice de Massa Corporal p=0,01 e OR= 1,8 (IC 95%1,1-2,9), tabagismo com p<0,01, OR=2,1 (IC 95%1,4-2,9) e depressão com p < 0,01 e OR=2,1 (IC 95%1,4-3,2). As variáveis triglicerídeos e o consumo habitual de álcool perderam a significância após ajuste para e idade, assim como a hipertensão. Colesterol HDL, diabetes, cardiopatia e comorbidades não listadas não mostraram diferença significativa na amostra. Ao compararmos os pacientes com estimativa de acometimento da área corporal menor e maior que 20%, as comorbidades hipertensão (p=0,03 e OR=1,69 (IC 95% 1,1 - 2,6) e diabetes (p<0,01 e OR= 2,9 (IC 95%1,6-5,4) mostraram diferença significativa. O tabagismo foi mais significativo entre os pacientes com estimativa de acometimento da área corporal menor que 20% (p<0,01 e OR 0,5 (IC 95% 0,3-0,8). As demais variáveis (cardiopatia, síndrome metabólica, depressão, comorbidades não listadas, uso de álcool, cintura abdominal alterada, Índice de Massa Corporal > 25kg/m2, triglicerídeos e colesterol HDL) não mostraram diferença entre os pacientes com maior e menor acometimento da área corporal. Conclusão: Nossos resultados confirmam a prevalência de significantes comorbidades em pacientes com psoríase quando comparado com os controles. Estes achados reforçam a necessidade da implementação de uma rotina de rastreamento para riscos metabólicos e cardiovasculares, assim como orientações sobre o estilo de vida e hábitos saudáveis. / Introduction: Psoriasis is a chronic inflammatory disease that affects the skin, scalp, nails and occasionally the joints. The prevalence of psoriasis varies from 0.6 to 4.8% of the world population and affects men and women alike. The disease has been associated with an increased risk of several comorbidities. The aim of this study is to evaluate the association between psoriasis and comorbidities such as hypertension, diabetes, metabolic syndrome, dyslipidemia, obesity, depression, smoking and alcohol use. Methods: A case-control study (psoriasis vs. no psoriasis) conducted in the Dermatology Outpatient Service of the Hospital de Clinicas de Porto Alegre. The evaluated parameters were: weight, height, blood pressure, waist circumference and diagnosis of comorbidity. In the patients with psoriasis the affected body surface area was also evaluated. Results: The study included 350 cases (55.1% women) and 346 controls (63.6% women). The average age was 49.81 years in the cases and 48.5 in the controls The risk factors that showed significant differences between the studied cases and controls were: increased waist circumference with p <0.01 and OR = 2.1 (95% CI 1.3 to 3.3), Body Mass Index p = 0.01 and OR = 1.8 (95% CI 1.1 to 2.9), smoking with p <0.01, OR = 2.1 (95% CI 1.4 to 2.9) and depression with p <0. 01, and OR = 2.1 (95% CI 1.4 to 3.2). The variables, triglycerides and habitual consumption of alcohol lost significance after adjustment for age and gender, as did hypertension. HDL cholesterol, diabetes, heart disease and non-listed comorbidities showed no significant difference in the sample. When comparing patients with an estimated involved body surface area smaller and larger than 20%, the comorbidities, hypertension (p = 0.03 and OR = 1.69 (95% CI 1.1 - 2.6) and diabetes (p <0.01 and OR = 2.9 (95% CI 1.6 to 5.4) showed a significant difference. Smoking was more significant among patients with an estimated involved body surface area of less than 20% (p <0.01 and OR 0.5 (95% CI 0.3-0.8). With the other variables (heart disease, metabolic syndrome, depression, non-listed comorbidities, alcohol use, altered waist circumference, Body Mass Index > 25kg/m2, triglycerides and HDL cholesterol) there was no apparent difference between patients with smaller or larger affected body surface areas. Conclusion: Our results confirm the significant prevalence of comorbidities in psoriasis patients compared with controls. The patients with more than 20% of the BSA affected are 1.69 times more likely to have hypertension and 2.9 times more likely to have diabetes. These findings reinforce the need to implement routine screening for metabolic and cardiovascular risks, as well as guidance on lifestyle and healthy habits.

A tendência de fumantes a direcionar sua atenção para estímulos associados ao cigarro é chamada viés atencional (VA). Uma revisão da literatura (2000-2008) indicou que o VA em fumantes pode operar durante todo o processo da atenção, sem um consenso sobre o papel da severidade da dependência. Uma tarefa experimental de atenção visual foi desenvolvida para investigar o VA em fumantes. Os participantes (47 fumantes, 50 não fumantes) responderam ao teste de Fagerström para dependência de nicotina, ao Teste de Triagem do Envolvimento com Álcool, Tabaco e outras Substâncias (ASSIST) e a uma tarefa de atenção visual. Os fumantes apresentaram maior VA para estímulos relacionados ao fumar, independente do estágio do processo de atenção (inicial ou mantida). Portanto, jovens fumantes já apresentam VA, indicando que fumar por poucos anos e com baixo nível de dependência altera a orientação inicial e a manutenção da atenção para esta classe de estímulos. / In smokers, attentional bias (AB) is the tendency to focus attention on tobaccorelated stimuli. A literature review (2000-2008) showed that smokers might show AB during all stages of the attentional process, and pointed to a lack of agreement about the role of the severity of dependence on AB. A visual probe task was developed to study AB in young smokers. The participants (47 smokers and 50 non smokers) answer the Fagerstrom Test for Nicotine Dependence; Alcohol, Smoking and Substance Involvement Screening Test (ASSIST), and a visual probe task. Smokers showed a greater AB for smoking-related cues than non smokers in all stages of attentional process. Therefore, young smokers already show AB to smoking cues, meaning that smoking even for few years and with low dependence can changes the orientation and the maintenance of attention to this kind of stimuli.

Tabagistas atendem seletivamente a estímulos ambientais relacionados ao cigarro, um processo cognitivo implícito denominado viés na atenção (VA). Contudo, não está claro se o VA persiste em ex-fumantes. Por isso, avaliou-se a influência do tempo de abstinência no VA em 62 ex-fumantes (de 50±11 anos) através de uma tarefa de atenção visual em computador. Independente do tempo de abstinência, os participantes evitaram as pistas associadas ao tabaco. Esta esquiva foi mais pronunciada em tempos de exposição maiores. Os ex-fumantes também atribuíram pouca valência emocional às imagens associadas ao cigarro e reportaram índices baixos de fissura antes e após a tarefa. O VA negativo e a menor valência emocional destas pistas podem constituir um processo de modulação da atenção típico da abstinência prolongada, no qual estratégias cognitivas são empregadas para manter este estado. Os resultados obtidos contribuem para a compreensão da cognição implícita na adição e sua importância no tratamento e prevenção do tabagismo. / Smokers selectively attend to smoking-related cues, an implicit cognitive process called attentional bias (AB). However, it is unclear whether former smokers present AB. Therefore, we evaluated the influence of abstinence time in VA in 62 exsmokers (50 ± 11 years-old) through a visual probe task. Participants avoided smoking cues despite of abstinence time. This avoidance was more pronounced in longer stimuli exposition. Former smokers also attributed little emotional valence to smoking cues and reported low craving rates both before and after the task. The negative AB and low emotional valence of smoking cues might constitute a process of attentional modulation typical of longer abstinence, in which cognitive strategies are employed to maintain this state. The results contribute to the understanding of implicit cognition in addiction and its importance to smoking treatment and prevention.
