Use of psychoactive substances in students at a public university

Introduction: The use of psychoactive substances by the student population has been the object of various studies in Brazil. Objective: To determine the prevalence of substance use among students. Methods: Quantitative study with a closed questionnaire based on standardized assessment instruments was developed. It consists of questions related to types of psychoactive substance use, abuse, frequency and duration of use, self-criticism regarding the use, consequences of use in relation to health, and misdemeanors committed under the influence of psychoactive substances. The sample included the participation of 268 students. A total of 183 (68.3%) questionnaires were analyzed, and only those with positive result for substance abuse at some point in life, the remainder, 85 (31%) questionnaires, had negative responses to psychoactive substances. Results: Students’ responses to the two years surveyed indicated that the first psychoactive substance used was alcohol (77.9%), followed by tobacco use (10.9%), and marijuana (7.6%). Of the students surveyed, 145 (79.2%) answered that still make use of psychoactive substances, and the current frequency of use varies from one or more times per week. When asked about the possibility of being or becoming drug addicts, 169 (92.3%) responded that they are not or will not become dependent. Conclusion: The results indicate the high rate of substance use among college students surveyed, and point to their contradiction to consider such psychoactive substances harmful to their health.

Association between bruxism, alcohol and tobaco use among brazilian students

The etiology of bruxism is not well defined. Different factors affecting the central nervous system are considered as risk factors for bruxism. Dental students are not immune to the bruxism, alcohol consumption and tobacco use, despite their training, knowledge of its effects and social responsibility. The purpose of this study was to evaluate the association between bruxism, alcohol consumption and tobacco use among Brazilian dental students. Participants were chosen among 180, 17-29 year-old students at the UNESP’s Dentistry School – Araçatuba Campus. They were divided into those with and without bruxism on the basis at validated clinical criteria. The clinical examinations were carried out by four standardized examiners (Intraexaminer and Interexaminer Unweighted kappa= 0.82, Weighted kappa= 0.89, respectively), in the clinic, with daylight and a tongue depressor. Bruxism was registered with the following categories: no wear facets, wear facets in enamel, dentine wear facets, facets wear half of the crown and wear facets more than 2/3 of the tooth crown. A self report validated questionnaire for alcohol consumption and tobacco use with 29 questions was completed by both groups. Fischer exact test and T-test were used and Odds Ratio and Confidence Interval was estimated. Bruxism was more frequent among cigarette smokers both in men (68.4%) and in women (56.8%). Among all respondents in this group, 82.6% reported that they would like to quit smoking and those who have tried previously to quit (76.4%) found it made them more stressed. Drinker was more frequent in the group with bruxism also (66.5% of the female and 73.5% of the male). 88.4% reported drinking alcohol because it “allows dealing with stress in an adequate way”. Results suggest a positive association between bruxism and alcohol consumption and tobacco use.

Diretrizes para cessação do tabagismo - 2008

Estas diretrizes constituem uma ferramenta atualizada e abrangente para auxiliar o profissional de saúde na abordagem do tabagista, recomendando atitudes baseadas em evidências clínicas como a melhor forma de conduzir cada caso. de forma reduzida e mais objetiva possível, o texto final foi agrupado em dois grandes itens: Avaliação e Tratamento. Os dois itens apresentam comentários e níveis de recomendação das referências utilizadas, bem como algumas propostas de abordagem, como por exemplo, redução de danos, em situações específicas ainda pouco exploradas, como recaídas, tabagismo passivo, tabagismo na categoria médica e uso de tabaco em ambientes específicos.

Perfil de fumantes atendidos em serviço público para tratamento do tabagismo

OBJETIVO: Avaliar o perfil dos fumantes que procuraram serviço público de cessação do tabagismo. MÉTODOS: Foram avaliados retrospectivamente os dados coletados durante a avaliação para a admissão no programa de cessação do tabagismo do Ambulatório de Tabagismo da Faculdade de Medicina de Botucatu/Universidade Estadual Paulista, na cidade de Botucatu (SP) entre abril de 2003 e abril de 2007. Variáveis demográficas, uso prévio de abordagem comportamental e/ou farmacológica e/ou tratamentos alternativos para o tabagismo, grau de dependência à nicotina e comorbidades foram avaliados em 387 fumantes. RESULTADOS: em nossa casuística, 63% dos tabagistas eram do sexo feminino. A idade média dos sujeitos foi de 50 ± 25 anos. Mais da metade dos fumantes (61%) não tinha cursado o ensino médio, e 66% tinham renda mensal menor que dois salários mínimos. O grau de dependência foi elevado/muito elevado em 59%, médio em 17% e baixo/muito baixo em 24%. Embora 95% dos pacientes apresentavam comorbidades, apenas 35% foram encaminhados ao programa por um médico. Mais da metade (68%) tinha feito pelo menos uma tentativa de cessação, 83% sem um programa de tratamento estruturado. CONCLUSÕES: Os tabagistas que procuraram assistência para cessar o tabagismo apresentaram desvantagem social, dependência à nicotina alta e tentativas anteriores de cessação sem tratamento estruturado. Portanto, a intervenção para o controle do tabagismo deve contemplar as características gerais dos fumantes nos serviços públicos para que seja eficaz.

Comparison of risk factors among blood donors, volunteers and replacement individuals, infected or not by hepatitis C virus

Hepatitis C is transmitted primarily parenterally by contaminated blood and is often associated with: intravenous drug abuse, invasive procedures, blood transfusions, acupuncture, tattooing, and alcohol and tobacco use. This study aimed to quantify and evaluate the risk factors among blood donors, volunteer blood donors and replacement individuals, infected or not by the C virus. The main transmission routes of C virus were identified in 55 men and 25 women (GI) monitored by the Ambulatory Unit of the Department of Tropical Diseases, Botucatu Medical School, and in 24 men and 26 women (GII), all active blood donors at the Bauru State Hospital Transfusional Agency. Both groups were similar in: tobacco and alcohol consumption, sexual behavior, tattooing and illicit drug use. The duration of alcohol and tobacco consumption and blood transfusions in GI were longer, whereas the option for steady partners, condom use, disposable materials and piercings were predominant in GII. In conclusion, the risk factors for hepatitis C demonstrate the necessity of health policies that act on the primary and secondary prevention levels (respectively, reduction of infection incidence and hepatopathy risk).

Caracterização epidemiológica e demográfica de homens com câncer de próstata

O estudo pretende identificar características demográficas e epidemiológicas em homens com câncer de próstata, atendidos no Hospital das Clínicas da Faculdade de Medicina de Botucatu/UNESP, entre 01/01/2000 e 31/01/2003. Foram colhidos dados em 78 de 94 prontuários, observando-se escolaridade, uso de tabaco, estado civil, idade, diagnóstico e sintomatologia. Utilizou-se metodologia quantitativa associada à estatística descritiva. Foram encontrados 50% com 1º grau incompleto, 27,39% não tabagistas, 87% casados, 43% entre 64 e 73 anos. Observou-se que 27,58% foram diagnosticados em 2000, sendo 63,20% aposentados e 20,70% com sintoma de jato urinário fraco. Apenas 20% tinham realizado exames preventivos e, desses, 77,90% possuíam 1º grau incompleto. O estudo foi feito nesse hospital por ser considerado de referência terciária da Direção Regional de Saúde de Botucatu -DIR XI¹. da amostra, 80% procuraram o serviço apresentando sintomas, o que leva a crer que ainda haja falta de orientação da população quanto ao câncer de próstata, principalmente quanto à incidência e prevalência relacionadas à idade, como fator de risco. O estudo evidencia subsídios para um melhor direcionamento da assistência a esses pacientes, permitindo um diagnóstico precoce e conseqüente possibilidade de cura, além da melhora na qualidade de vida.

Metabolic syndrome and its associated risk factors in Brazilian postmenopausal women

Objective To evaluate the prevalence of metabolic syndrome (MetS) and its associated risk factors in Brazilian postmenopausal women.Methods In this cross-sectional study, a total of 368 postmenopausal women, aged 40-75 years, seeking health care at a public outpatient center in Southeastern Brazil, were included. According to the US National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) guidelines, MetS was diagnosed in subjects with three or more of the following: waist circumference >= 88 cm, blood pressure >= 130/85 mHg, triglycerides >= 150 mg/dl, high density lipoprotein cholesterol <50 mg/dl and glucose >= 110 mg/dl. Data on past medical history, tobacco use, anthropometric indicators, and values of C-reactive protein (CRP) were collected. Multivariate analysis, using a logistic regression model (odds ratio, OR) was used to evaluate the influence of various simultaneous MetS risk factors.Results The prevalence of having at least three, four and five MetS diagnostic criteria were met in 39.6%, 16.8% and 3.8% of the cases, respectively. The most prevalent risk factor was abdominal obesity, affecting 62.5% of women. The risk of MetS increased with a personal history of diabetes (OR 5.95, 95% confidence interval (CI) 2.82-12.54), hypertension (OR 4.52, 95% CI 2.89-7.08), cardiovascular disease (OR 2.16, 95% CI 1.18-3.94) and high CRP (>1 mg/dl) (OR 3.35, 95% CI 1.65-6.79). Plasma CRP levels increased with the number of MetS components present. Age, time since menopause and smoking had no influence, while hormone therapy reduced MetS risk (OR 0.64, 95% CI 0.42-0.97).Conclusion Metabolic syndrome was highly prevalent among Brazilian postmenopausal women seeking gynecologic health care. Abdominal obesity, diabetes, hypertension and high CRP were strong MetS predictors and hormone therapy appeared to play a protective role for this condition.

Tabagismo, abandono do fumo e os otorrinolaringologistas do estado de São Paulo

Os otorrinolaringologistas estão diretamente envolvidos no diagnóstico e tratamento de doenças provocadas pelo cigarro, incluindo o câncer das vias aéreas superiores. É importante que os especialistas estejam capacitados a tratar o tabagismo e a dependência da nicotina. Também se sabe que há fumantes entre os próprios médicos. OBJETIVO: Pesquisar as opiniões e condutas de otorrinolaringologistas do Estado de São Paulo frente ao tabagismo e à dependência química da nicotina, e avaliar o hábito tabagístico dos especialistas. FORMA DE ESTUDO: Corte transversal. MATERIAL E MÉTODOS: Foram selecionados aleatoriamente 600 otorrinolaringologistas do Estado de São Paulo. A esses especialistas foi enviado, em março de 2005, por correio, um questionário padrão. Foram analisadas as respostas recebidas no período de março a maio de 2005. RESULTADOS: Foram recebidas 209 respostas. Nestas, 97 profissionais (46,4%) avaliaram sua familiaridade com os meios de tratamento da dependência de nicotina como regular e 60 (28,7%) como insatisfatória. Dos participantes do estudo, 144 (68,9%) nunca fumaram, 50 (23,9%) são ex-fumantes, nove (4,3%) são fumantes ocasionais e seis (2,9%) são fumantes. CONCLUSÃO: A prevalência de tabagistas na amostra de 209 otorrinolaringologistas do Estado de São Paulo foi de 7,1%.

Métodos para abandono do tabagismo e tratamento da dependência da nicotina

O tabagismo está relacionado a 30% das mortes por câncer. É fator de risco para desenvolver carcinomas do aparelho respiratório, esôfago, estômago, pâncreas, cérvix uterina, rim e bexiga. A nicotina induz tolerância e dependência pela ação nas vias dopaminérgicas centrais, levando às sensações de prazer e recompensa mediadas pelo sistema límbico. É estimulante do sistema nervoso central (SNC), aumenta o estado de alerta e reduz o apetite. A diminuição de 50% no consumo da nicotina pode desencadear sintomas de abstinência nos indivíduos dependentes: ansiedade, irritabilidade, distúrbios do sono, aumento do apetite, alterações cognitivas e fissura pelo cigarro. O aconselhamento médico é fundamental para o sucesso no abandono do fumo. A farmacoterapia da dependência de nicotina divide-se em: primeira linha (bupropiona e terapia de reposição da nicotina), e segunda linha (clonidina e nortriptilina). A bupropiona é um antidepressivo não-tricíclico que age inibindo a recaptação de dopamina, cujas contra-indicações são: epilepsia, distúrbios alimentares, hipertensão arterial não-controlada, abstinência recente do álcool e uso de inibidores da monoaminoxidase (MAO). A terapia de reposição de nicotina pode ser feita com adesivos e gomas de mascar. Os efeitos da acupuntura no abandono do fumo ainda não estão completamente esclarecidos. As estratégias de interrupção abrupta ou redução gradual do fumo têm a mesma probabilidade de sucesso.

Alcohol dehydrogenase 3 genotype as a risk factor for upper aerodigestive tract cancers

Objective: To assess alcohol dehydrogenase 3 (ADH3) polymorphism at position Ile349Val as indicator of risk factor for upper aerodigestive tract (UADT) cancer to verify its association with UADT cancer in nonalcoholic or nonsmoking individuals.Design: Cross-sectional study.Setting: Primary care or referral center.Patients: the study group consisted of 141 consecutive patients with newly diagnosed squamous cell carcinoma of the oral cavity, oropharynx, hypopharynx, or larynx admitted for surgical treatment. The comparison group consisted of 94 inpatients without cancer from the A. C. Camargo or other São Paulo (Brazil) hospital and 40 healthy individuals.Intervention: All participants were interviewed and data were collected using a structured questionnaire. After written informed consent was obtained, 20 mL of blood was collected in heparinized tubes.Main Outcome Measures: Odds ratio for ADH3 genotypes using logistic regression models.Results: After adjustment for sex, age, tobacco use, and history of cancer in first-degree family relatives, a significantly higher odds ratio for UADT cancer was observed among individuals with AA genotype and low cumulative alcohol consumption (:5 100 kg of ethanol) (odds ratio=3.8 [95% confidence interval, 1.5-9.7]). A 4-fold increase in odds ratio for UADT cancer among individuals with AA genotype and low tobacco consumption (:525 pack-years) was also found in the adjusted model.Conclusions: These results suggest that genotype AA may be a risk factor for UADT cancer, especially in individuals with low alcohol or tobacco consumption. However, further epidemiological case-control or cohort studies, preferably prospective, are needed to establish the exact role of ADH3 polymorphism and its association with the development of UADT cancers.

Effect of total abdominal hysterectomy on ovarian blood supply in women of reproductive age

Objective. The purpose of this study was to evaluate the effect of total abdominal hysterectomy on ovarian blood supply using transvaginal color Doppler ultrasonography in women of reproductive age. Methods. This prospective study included 61 women aged 40 years or younger who were divided into 2 groups: group 1, comprising 31 patients who underwent total abdominal hysterectomy (TAH), and group 2, comprising 30 women with no abnormalities. Inclusion criteria included normal ovarian function at baseline, with basal follicle-stimulating hormone levels of less than 15 mUI/mL, normal body weight, no tobacco use, and no history of laparotomy or ovarian disease. Ovarian arterial blood supply by determination of the pulsatility index (PI) on Doppler analysis and ovarian volume on transvaginal ultrasonography were assessed at baseline and at 6 and 12 postoperative months. The Student t test, profile analysis, and Friedman and Mann-Whitney tests were used in the statistical analysis of data. Results. Statistical analysis of baseline data revealed that both groups were homogeneous. At months 6 and 12, greater ovarian volumes and lower PI values were observed in patients who underwent TAH (P < .05). By the end of the study, in 8 of the 31 patients who underwent TAH (25.5%), benign ovarian cysts were observed. in the control group, all the parameters studied remained unchanged. Conclusions. The reduced PI values observed on Doppler ultrasonography suggested a decrease in the resistance flow in the ovarian arteries in women of reproductive age who underwent TAH.
